Abstract

The invention discloses an electrostatic protection method and equipment, computer equipment and a readable storage medium. The electrostatic protection method is applied to the preparation of a motor, and comprises the following steps: setting an electrostatic protection device on a preset pin of a power module of a motor; and performing plasma surface treatment on the motor, wherein the electrostatic protection device comprises a short circuit assembly, a shielding assembly and an electrostatic protection circuit. According to the method, the specific pin of the transistor in the power module is short-circuited, shielded or connected with the protection circuit by using the specific electrostatic protection device, so that effective electrostatic protection of the electrode with relatively low withstand voltage is realized, the operation is convenient and fast, the stability is good, and the power module is prevented from being damaged by static electricity generated in the electrodepreparation process.

Description

Technical field[0001]The embodiments of the present invention relate to motor manufacturing technology, and in particular to a static electricity protection method, equipment, computer equipment and storage medium.Background technique[0002]In the preparation process of motors such as Belt-Driven Starter Generator (BSG), in order to improve the safety of the motor, the power module needs to be filled with flame retardant glue and covered with a certain seal on the flame retardant glue. Adhesive, plasma surface treatment (Plasma) to the motor, the surface tension and activity of the two adhesives are strengthened, the flame-retardant adhesive can avoid cracks, and the sealant and the PCB shell are more closely bonded.[0003]During the plasma surface treatment of the motor, the nozzle will automatically complete a circle around each power module. When the nozzle is close to the pins of the power module, static electricity will be generated. The transistor contained in the power module w...
