How To Improve The Welding Accuracy Of Ultrasonic Plastic Welding Machine？

Ultrasonic plastic welding machine has the advantages of high welding efficiency, high welding strength and good welding quality, so it is used by factories to weld large-scale plastic products. In the process of welding plastic workpieces, the factory often has the problem of inaccurate welding accuracy, which leads to the increase of bad product rate and certain economic losses to the factory. Therefore, when using ultrasonic plastic welding equipment, the factory should master the welding skills and improve the welding accuracy.

According to the experience of using ultrasonic plastic welder, several methods to improve the welding accuracy are summarized. First, we should have an in-depth understanding of the welding mechanical system and the actual situation of various mechanical movements of the welding head. If necessary, we can transform the mechanical system of the welding head according to the welding requirements of plastic workpieces to ensure the accuracy of the movement of reversing and lifting of the welding head. For example, we can change the compression amount of the reset spring of the welding head or the amplitude of lifting after welding by changing the air pressure, so as to change the longitudinal accuracy of the welding head. Second, do a good job in the maintenance of the ultrasonic plastic welder to ensure that all parts are in good working condition. For example, do a good job in the daily lubrication of the rolling spline pair to reduce its wear during operation. Once it is found that the wear is too serious, replace it in time to avoid affecting the accuracy of the movement of the welding head.

Due to the fast welding speed of ultrasound plastic welding machine, once there is a problem in welding accuracy and the factory can not find it in time, it will produce a large number of bad products and bring serious economic losses to the factory. In order to further improve the welding accuracy of the equipment, the ultrasonic welder machine manufacturer has designed an alarm system for the equipment. When the system detects that the movement of parts such as welding head has deviated from a certain range of the set value, it will send an alarm. The factory can troubleshoot the ultra sonic plastic welding machine according to the alarm information and stop the loss in time.
