Over the years of repairing ultrasonic equipment, we have identified the following common faults:

The cleaning water surface does not vibrate, and there is debonding between the vibrator and the load.
The mold head is misaligned.
There is no display when turned on, and there is an overload or overcurrent during the welding process.
The current is too high during testing.
Insufficient welding capacity during the welding process, or the welding heat is too intense.
The vibrator has leakage waves.
The button does not work when pressed.
There is an issue with the travel protection.
There is sound, but the power cannot be adjusted.
The ultrasonic intensity is insufficient.
The transducer ceramic is cracked.
The power tube is burned out.
The voltage stabilization part is not functioning properly.
There are problems with the inductor and isolation transformer.
The vibrator wire is disconnected.
These faults can occur due to various reasons such as wear and tear, improper use, or component failures. It is important to regularly inspect and maintain ultrasonic equipment to identify and address these issues promptly. Our team of experienced engineers at Rongji Electromechanical is well-versed in diagnosing and repairing these common faults, ensuring that your ultrasonic equipment is restored to its optimal performance.

Principles for Ultrasonic Equipment Repair:

  1. Observe first, understand next, and then act, from the outside in.

When encountering problems with ultrasonic equipment, one should not blindly continue operating or rush to take action. It is essential to first inquire with the frontline production staff on duty that day to understand clearly when the problem occurred and the actual fault situation. Check if there were any voltage fluctuations, thunderstorms, or unauthorized disassembly at the scene.

If there is no response from the equipment, it is likely that a fuse or short circuit has occurred. In this case, focus on checking the electrical situation and measuring impedance with a multimeter. For unfamiliar ultrasonic equipment, do not dismantle it immediately. It is necessary to research its structure and related manuals online. When disassembling, pay attention to the coordination process of each part, keep the parts organized, and label anything that needs to be remembered. If necessary, draw simple diagrams. Acting rashly may escalate the problem or even make it impossible to reassemble the equipment.

  1. Simple before complex

Start by ruling out peripheral issues. Factors such as the surrounding environment, electricity, load, raw materials, and molds can all affect the normal operation of the equipment. First, confirm whether these aspects are functioning properly. Clean the equipment and its environment, as this sometimes resolves the issue. For example, oil and dust on some buttons can cause poor contact. If possible, swap two ultrasonic devices or other components for comparison to confirm the problem’s general direction. Only after confirming that the ultrasonic device itself is the issue should you disassemble it or send it out for repair.

For equipment that has had problems in the past, there is a high likelihood of similar failures recurring, so pay close attention to these areas.

  1. Address mechanical issues first

Mechanical problems can be seen with the naked eye, such as issues with the mold. Even if the transducer is working, the equipment may not function properly, which can be determined through touch and comparison. If mechanical problems are not addressed and one blindly searches for electrical causes, it will be like looking for a needle in a haystack and will never be resolved. Admittedly, dealing with mechanical issues can be somewhat challenging, but they must be resolved.

Global Touch Screen Repair Centers,Professional maintenance touch screen

Touch screen is a special human-machine dialogue device that has been widely used in daily life, production, and commercial occasions. Touch screens are mainly divided into several forms: resistive screens, capacitive screens, infrared screens, and ultrasonic screens. Because it has too close contact with people and a large part of it is a vitreous structure, the probability of touch screen damage is relatively high. The most common area of damage to touch screens is often the surface touch outer screen, commonly known as the “touchpad,” which can be used normally after replacement.
Rongji Electromechanical Maintenance has been using touch screens in the industrial, commercial, medical, and military fields for over 20 years. Currently, in these areas, resistance screens are mostly used due to reliability and safety considerations. The automotive industry uses both resistive and capacitive screens, and touch screens in this field, whether they are capacitive or resistive, can be repaired by us.

Step 1: Remove the back cover and remove the motherboard screws

Touch screen manufacturers, considering profit, often design touch panels and even LCD components as non-standard products, and do not disclose the drivers and circuits to the public. If standard touch panels and controllers are installed, they are often not compatible.

Step 2: Remove the outer shell and use a hair dryer to heat up the film

Longi Electromechanical Company has a team of engineers who have been researching the reverse engineering of various touch screens for a long time. They have explored a solution and replacement process for touch screen accessories from the bottom layer or touch panel technology. They can perfectly use the touch panel and other accessories produced by Longi Company to replace the original ones, and solve problems for customers while significantly reducing maintenance costs.

Step 3: Peel off the film and remove the touchpad

Most resistive screens and a small portion of capacitive screens can be purchased from touch pads produced by Longi Company. Following the replacement method we provide, they can be installed and used normally.

Step 4: Apply double-sided tape to the touch screen border and place a new touch pad on it

A small number of resistive screens and some capacitive screens, due to their special design, customers can send the entire touch screen to Rongji Company by mail. We use professional software analysis and judgment, and through hardware processing and software patching methods, we can achieve cracking and replacement.

Step 5: Install the motherboard LCD and flip it over to test if the touchpad is functioning properly

Similarly, for accessories such as LCD, high-voltage bars, and light tubes, similar methods can be used to achieve functional repair of touch screens without affecting their use.

Step 6: After successful testing, apply the film and replace the touchpad

During the use of touch screens, in addition to the mentioned accessory issues, there may also be circuit failures such as power boards or motherboards. For example, it is not displayed, or the display is abnormal. This situation belongs to a hardware malfunction of the circuit. The entire machine can be sent to the headquarters of Longi Company by mail, and we will use circuit maintenance methods for repair.

A special situation is when there is a problem with the touch screen software, such as the battery running out or data being lost. This situation is quite troublesome. If the customer has backed up data, we can help them re-enter it and it can be used normally. If the customer does not have backup data and cannot contact the equipment manufacturer to find the data, the only solution is to rewrite the appropriate touch screen program according to the process and equipment flow. As touch screens are secondary development applications, the programming difficulty is not too high. However, it will take time to pair with other devices in the system, such as PLCs.

Longi Electromechanical Company has repaired the following brands of touch screens:

Siemens touch screens, Proface touch screens, Mitsubishi touch screens, Fuji touch screens, Panasonic touch screens, OMRON touch screens, WEINVIEW touch screens, Koyo touch screens, Delta touch screens, Toyota JAT touch screens for air-jet looms, Staubli touch screens, Beijer touch screens, AB (Allen-Bradley) Rockwell touch screens, Hitech touch screens, Schneider touch screens, Toyo touch screens, DMC touch screens, MCGS (Kunlun Tongtai) touch screens, Touchwin touch screens, General touch screens, Red Lion touch screens, B&R (Beckhoff & Rautert) touch screens, LG touch screens, M21 touch screens, Fatek (Yonghong) touch screens, IDEC (Waizu) touch screens, Wecon touch screens, Pingtong touch screens, Fanuc touch screens, Lenze touch screens, Advantech touch screens, Hakko touch screens, Yushin touch screens, UNIOP touch screens, Shihlin (See) touch screens, Parker touch screens, Eura touch screens, and Hakko White Light touch screens, among others.

Please note that some of the brand names mentioned may be trademarks or registered trademarks of their respective companies. The listing here is for informational purposes only and does not imply any affiliation or endorsement by Longi Electromechanical Company or any of the mentioned brands.

Common Touch Screen Issues:

Display is visible but cannot be touched or clicked, or the touch response is poor. In most cases, this is due to a faulty touch panel. Sometimes recalibrating can solve the problem, but mostly the touch panel needs to be replaced.

The touch screen does not display anything, and even the indicator lights are not on. This situation usually indicates a problem with the power supply unit of the touch screen.

The touch screen functions but displays a black screen, while the indicator lights are normal. This is typically caused by a burned-out backlight tube inside the screen.

The touch screen displays a distorted image or abnormal colors. This is often a problem with the liquid crystal display (LCD) or could be caused by issues with the connecting cables.

The touch screen displays a communication error, and the response to touch is very slow. This issue is not with the touch screen itself but rather with the connection between the Programmable Logic Controller (PLC) or other devices and the touch screen. In many cases, the problem lies with the connecting cables or plugs.

Global Servo CNC maintenance center

Global Servo CNC maintenance center,Professional maintenance of servo CNC systems

Remember to contact Longi Electromechanical for any issues with servo and CNC systems!

Servo systems differ from VFDs in that they offer higher precision and typically come with delicate encoders. Servo motors are synchronous motors with magnets inside, and if not handled carefully during disassembly and assembly, their original performance may not be restored. Additionally, different servo drivers cannot be used interchangeably with other servo motors. This means that during the repair of a servo driver, a corresponding servo motor and cable plug are required for proper testing. Similarly, repairing a servo motor also requires a matching servo driver for testing, which can pose challenges for many maintenance personnel.

As for CNC (Computer Numerical Control) systems, most are embedded industrial computer types with closed control systems. Each manufacturer has its own design ideas, programming methods, wiring, and communication architectures, making them incompatible with one another.

Longi Electromechanical Company has designed various styles of servo and CNC maintenance test benches to test the working conditions of different CNC systems, servo drivers, or servo motors. When servo systems encounter issues such as no display, phase loss, overvoltage, undervoltage, overcurrent, grounding, overload, module explosion, magnet loss, parameter errors, encoder failures, communication alarms, etc., the corresponding platform can be used to test and diagnose the problem.

Repair Hotline: +8618028667265 Mr. Guo

After resolving these issues, the servo system also needs to undergo a simulated load test to avoid problems such as overcurrent under load conditions, even if it performs well under no-load conditions. This ensures that the servo system is fully functional and ready for use in actual applications.

For the CNC system, it is also necessary to conduct simulated operation before normal delivery to avoid any discrepancy with the on-site parameters. Currently, Rongji Electromechanical possesses hundreds of servo and CNC test benches, which can quickly identify problem areas and promptly resolve issues. With these advanced testing facilities, Longi Electromechanical ensures the smooth operation and reliability of the repaired equipment.

The Servo and CNC Repair Center established by Longi Company currently has over 20 skilled and experienced maintenance engineers who specialize in providing repair services for different brands and specifications of servo and CNC systems. They implement tailored repair solutions for different maintenance projects, ensuring efficient and high-quality service for customers. By helping customers save valuable production time and reducing their maintenance costs, Rongji truly cares about the urgent needs of its customers and strives for common development and progress together.

Longi Electromechanical Company specializes in the maintenance of VFDs and strictly requires its engineers to followlow standard operating procedures. Upon receiving a unit, the engineers carefully inspect its exterior and clarify any fault conditions with the customer before beginning work. Any removed circuit boards are cleaned using ultrasonic cleaning equipment. Repaired circuit boards are coated with high-temperature and high-pressure-resistant insulating paint, dried in a drying machine, and then reinstalled in the VFD, with measures taken to prevent corrosion and interference.

The repaired VFD will undergo a simulated operation with load using a heavy-load test bench to avoid any potential issues that may arise under actual load conditions on site.

When it comes to VFD maintenance, most cases are related to the equipment on site. Sometimes a standalone unit may have been repaired, but it doesn’t work properly when installed on site. In some cases, the problem lies with the system rather than the VFD itself. For such issues, if the customer requests on-site service, we will do our utmost to resolve the problem for them. If the location is far away, such as in another province, we can use tools like video conferencing and phone calls to allow our engineers to remotely diagnose and resolve the on-site issues for the customer.
