[0002] At present, the production of diodes will go through the pickling process. The pickling uses various acids and water to chemically corrode the edge surface around the chip PN junction to improve mechanical damage, remove impurities adsorbed on the surface, reduce the surface electric field, and make the PN junction breakdown occur first from the body to obtain a reverse breakdown voltage close to the theoretical value.

[0003] The application number is 202221988639.1. In a diode production equipment, it is proposed that: "The existing pickling box has a simple structure. When the diode chips are immersed in the pickling solution in batches, there is stacking between the diode chips, which makes the pickling effect of some chips poor. The staff's operation of spreading the chips is cumbersome, which makes the pickling of the diode chips labor-intensive." The problem is designed, and "a flipping device is designed. When the diode chips are pickled, the stepper motor drives the flipping box to flip the angle regularly in the pickling chamber of the chip pickling box, which can prevent the diode chips from stacking during the pickling process. The pickling effect is affected. Through the provided lifting device, after the pickling is completed, the assembly frame and the water filter net are lifted upward by lifting the pull ring. This can filter out the pickling liquid and lift the diode chips in a concentrated manner, which is beneficial to improving the efficiency of diode chip removal."

[0004] However, when the above device is in use, since the diode chip is located in the pickling liquid during the material taking process, the pickling liquid may leak during the material taking process, polluting the environment while reducing the safety of the staff.
