Description

Technical Field

[0001] The utility model relates to the technical field of diode processing, in particular to a diode pin welding device with high precision. Background Art

[0002] A diode is an electronic device made of semiconductor materials. A diode has two electrodes, the positive electrode is also called the anode, and the negative electrode is also called the cathode. When a forward voltage is applied between the two electrodes of the diode, the diode is turned on. When a reverse voltage is applied, the diode is cut off. The conduction and cutoff of the diode are equivalent to the on and off of a switch. The diode has unidirectional conductivity. When processing the diode, a welding device is required to weld its pins.

[0003] For example, the utility model with publication number CN202221930691.1 discloses a fast recovery diode wire bonding device. This device, by providing a base, a fixing platform, a fixing tube, an elastic member, a connecting rod, and a pressure rod, can effectively fix a circuit board and a fast recovery diode. This provides a more stable fixation, ensuring that the pins remain stable and do not shake during welding, thereby improving welding quality and efficiency. However, the positioning slots on the fixing platform can only fix a single type of diode, resulting in certain limitations in use.

[0015] 1. The utility model adopts the setting of the positioning component. When positioning the circuit board, the first step is to rotate the dial block to align it with the limit groove on the pressure plate.

Then, the diode pins are inserted into the connection holes on the circuit board one by one. After that, the pressure plate is covered and the dial block is rotated to limit the top of the pressure plate. At this time, the spring will push the clamping plate under the limit of the pressure plate and the slide rod to clamp the circuit board in position, and the sponge pad will press the diode in the middle.

The two ends of the guide groove are horizontal. Therefore, after flipping, when the slide column moves to the two ends of the guide groove, the rotation angle of the bracket can be locked, so that the bracket can remain horizontal, thereby enhancing stability during welding and avoiding affecting the welding accuracy of the diode pins.
