Electrostatic blowing foreign matter removing device

Abstract

The invention discloses an electrostatic blowing foreign matter removing device which comprises a first support, a second support, an electrostatic generator, a blowing nozzle, a material channel, a first actuator, a slider, a probe and a conveying device. The second support is fixed on the first support, the blowing nozzle is fixed on the second support, wind passes the electrostatic generator and is introduced into the blowing nozzle and blown out, the slider is slidably connected with the first support, the probe is fixed on the slider, the material channel is arranged between the slider and the second support and provided with a hollow bottom, and the first actuator drives the slider to vertically move, so that the probe contacts with products on the material channel. According to thedevice, a high-voltage negative charge and compressed air are combined, blowing is implemented under motion of a relay, foreign matters in the relay can be effectively separated in a blowing manner, motion reliability of the relay is ensured, and yield is greatly increased. Besides, the device is additionally provided with the conveying device, the products are automatically fed, a lot of manpowerand material resources are saved, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of relay production, in particular to a device for removing foreign objects by electrostatic blowing. Background technique [0002] The prevention of foreign matter in the relay production industry has always been an important control item. The presence of foreign matter will lead to the occurrence of fatal defects such as non-conduction of relay contacts, internal short circuit, and poor withstand voltage. There are many types of foreign objects, generally there are foreign objects on the relay body, such as: resin material foreign objects, metal foreign objects; foreign objects such as: human sebum flakes, hair, dust, etc. [0003] The traditional method of removing foreign matter is to fix the blowing pipe on the jig or equipment, and when the product moves, blow air at the designated part to achieve the purpose of removing foreign matter. However, due to the existence of static electricity, the removal effect of ...

AI Technical Summary

Problems solved by technology

However, due to the existence of static electricity, the removal effect of foreign matter is often not good, because static electricity will make tiny foreign matter adsorb on the surface or groove of the relay, and the normally closed contacts of the relay are always closed, so foreign matter mixed between the contacts is also difficult to blow. remove
