Problems solved by technology

Although this technical solution has realized the assembly line of pickling, there is no need to wait in batches, and the efficiency of pickling has been improved, but this technical solution cannot fully stir the pickling solution to pickle the semiconductor diodes and does not do any damage to the suspension mechanism. Protective measures, the pickling solution has strong corrosiveness, and the suspension mechanism is soaked in it for a long time, which will cause corrosion to the suspension mechanism, thereby affecting the pickling effect of the pickling solution on the semiconductor diode; the use of this invention is limited

Abstract

The invention belongs to the technical field of semiconductor diodes, and specifically discloses a semiconductor diode acid pickling system. The semiconductor diode acid pickling system comprises a barrel, a first guide rod, a telescopic rod and an acid pickling box; the first guide rod is mainly used for colliding with a first plate during rotating so that the acid pickling box shakes up and down, simultaneously, a first sliding telescopic rod shakes up and down inside the acid pickling box to carry out telescoping and reciprocating cooperatively, stirring is carried out inside the acid pickling box constantly, and semiconductor diodes inside the acid pickling box are in sufficient contact with an acid pickling solution, so that the acid pickling efficiency and effect of the semiconductordiodes are improved; simultaneously, a first seal ring on the outer layer of the first sliding telescopic rod and a sealing unit are used for sealing the first sliding telescopic rod, and the corrosion of the acid pickling solution on the first sliding telescopic rod is slowed down, so that the service life of the first sliding telescopic rod is prolonged, and then the service life of the semiconductor diode acid pickling system is prolonged.

Description

technical field [0001] The invention belongs to the technical field of semiconductor diodes, in particular to a semiconductor diode pickling system. Background technique [0002] A semiconductor diode refers to a two-terminal electronic device that utilizes the characteristics of a semiconductor. The most common semiconductor diodes are PN junction diodes and metal semiconductor contact diodes. Their common feature is the asymmetry of the volt-ampere characteristics, that is, the current exhibits good conductivity in one direction, but high resistance in the opposite direction. It can be used as rectification, wave detection, voltage stabilization, constant current, variable capacity, switch, light emitting and photoelectric conversion, etc. Tunnel diodes for ultra-high frequency amplification or ultra-high-speed switching can be made by using the tunnel effect of carriers in highly doped PN junctions. With the rapid development of society, the application of semiconducto...
