The failure of ultrasonic spot welding machine is related to many factors, so we should not take it lightly when making repairs. What are the specific matters that need to be paid attention to in the maintenance and failure of ultrasonic spot welding machines? Let's take a look.

1. For the failure of the ultrasonic plastic welding machine, do not rush to start, first ask the failure process and phenomenon.

2. First check whether the repaired ultrasonic equipment has obvious maintenance history, ultrasonic welding, ultrasonic mold temperature and service life, and then check the inside of the machine.

3. Before disassembling the device, troubleshoot the surrounding and determine the internal fault. Then remove the fault factor. Otherwise, the ultrasonic spot welding machine may be dismantled blindly, resulting in the equipment getting worse and worse.

4. Power test, listen to its sound, touch, measure parameters, determine the cause of failure, and then carry out maintenance.

5. Clean and repair the ultrasonic welder. For electrical equipment with serious pollution, first clean its buttons, connection points and contacts, and check whether the external control point keys are invalid;

6. Many failures are caused by dust and conductive dust, which can usually be eliminated after cleaning. Provide skilled and experienced technical support for professional production of ultrasonic machines and plastic welding machines based on maintenance knowledge.

In the process of using ultrasonic spot welding machine, there are three principles that need to be followed, so what are these principles? let me see.

1. The entire welding surface should be in even and close contact and be kept on the same plane as much as possible. This shape allows for even energy transfer, which facilitates consistent and controllable welding results and reduces the possibility of glue spillage.

2. To provide a method for uniformizing the two welding surfaces of an ultrasonic spot welding machine. The design of the supporting plastic parts can use pins and jacks, ladders or grooves instead of being fastened to the welding head or the die to ensure accurate and stable alignment and avoid marks;

3. The initial contact area of ​​the two welding surfaces needs to be reduced to reduce the total energy required for initial and subsequent complete melting, reducing the contact time between the welded joint and the workpiece, thereby reducing marks and glue spillage.
