Description

Technical Field

[0001] The utility model relates to the technical field of electronic device processing tooling, in particular to a diode chip oxide skin removal device. Background Art

[0002] The diode patch is an important electronic component, widely used in electronic circuits. Its main function is to guide the current in the direction of unidirectional conduction. It only allows the current from the anode to the cathode to pass, but not the current flowing in the opposite direction. The diode patch is electrically connected to each electrode sheet through solder. In order to ensure the good welding performance of the surface of the diode patch and ensure that the conduction is not affected, the oxide skin on the surface of the diode patch needs to be removed before assembly. Most of the existing oxide skin removal methods directly use mixed solutions to dissolve the oxide skin components, but they cannot quickly and effectively completely remove the oxide skin of the diode patch, and there will be a certain amount of oxide residue. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a device for removing oxide skin from diode patches. Before using a mixed solution to dissolve the oxide skin, a rotating device is first used to drive the diode patches to rub against each other, which has high working efficiency and can effectively remove the oxide skin on the surface of the diode patches.

[0006] Furthermore, a hook for locking the net cover is arranged around the body of the net tank, a cover plate is connected above the net cover, two holes are arranged on the cover plate, and the hole spacing and hole diameter of the holes match the two levers of the rotating drive device.

[0007] Furthermore, the cover plate is fixedly connected to the mesh cover via a connecting rod.

[0009] Furthermore, a groove is provided on the top surface of the rotating tray, and the groove is matched and connected with the protrusion at the bottom of the net tank.

[0010] Furthermore, the slide rod passes through the four corners of the lifting platform, and a limit head is provided at the lower end of the slide rod.

[0011] Furthermore, the rotation driving device is a motor, and the shifting rod is arranged at the output end of the motor.

[0012] Furthermore, the lifting drive device is a hydraulic rod.

[0013] Furthermore, the fan is arranged on the box body opposite to the sealed door, and the vacuum cleaner is arranged on the box body beside the sealed door.

[0014] Furthermore, the sealing door is made of a transparent material, and one side of the sealing door is connected to the box body via a hinge.

[0015] Compared with the prior art, the utility model has the following obvious advantages:

[0016] 1. The utility model contains a plurality of diode patches in a net can, and the motor and the lever connected to the lower end thereof drive the net can to rotate at high speed.
