The invention belongs to the technical field of diodes, in particular to a processing system of acid pickling of a diode. The processing system comprises a cylinder body, an air cooling module, a water cooling module, an exhaust gas processing box and an air pressure elevating module. The water cooling module comprises a first motor, a gear shaft, an annular plate, a gear and a spiral pipe. The air cooling module comprises a first hollow rotation shaft, a first rotation disc, a rotation unit, a second hollow rotation shaft, a first pipe and a nozzle. According to the invention, by reducing temperature generated in the acid pickling process, and the vaporized acid pickling solution is liquidated; on one hand, through the rotary spiral pipe, the outer wall of a cylinder body is cooled; on the other hand, through mutual cooperation between a first rotation plate, a torque spring and a cam, gas is uniformly gathered and the volatile acid pickling solution is cooled; and the acid pickling efficiency and effects of the diode are improved.
Description
technical field [0001] The invention belongs to the technical field of diodes, in particular to a diode pickling treatment system. Background technique [0002] A diode is an electronic component, a device with two electrodes that only allows current to flow in one direction. The most common function of a diode is to only allow current to pass in a single direction (called forward bias), and to block it when it is reversed (called reverse bias). So a diode can be thought of as the electronic version of a check valve. After the existing diodes are welded, the surface of the diodes needs to be treated, and a pickling device needs to be used in the process. [0003] There are also technical solutions for diode pickling in the prior art, such as a diode pickling machine disclosed in a Chinese patent with application number 201510919053.8, which includes a pickling box, a base, an acid tank, a bracket, a liquid supply pipe, and a current collector. Hood, exhaust fan, exhaust p...
