It is widely used in the bonding welding of thyristors, LEDs, diodes, triodes, IC chip light circuits. The structure of ceramic splitter is very precise and complex. It is a typical precision and fine difficult-to-process product. The material has high hardness and small size.

[0031] The right-angle motor 12 is turned on by operating the control panel 16. Under the support of the conveyor frame 2 and the support of the chain 15 by the rear sprocket 14, the right-angle motor 12 drives the front sprocket 13 to rotate, and the front sprocket 13 drives the chain 15 to move.
