A high-frequency and high-speed pcb grinding device with automatic cleaning function

Abstract

The invention belongs to the technical field of grinding devices, in particular to a high-frequency and high-speed PCB grinding device with automatic cleaning function, comprising a support plate; a baffle plate is connected to the support plate, and the support plate is close to the top surface of the baffle plate A sliding cavity is symmetrically arranged on the top, a sliding plate is slidably connected to the top of the sliding cavity, a support cavity is connected to the side wall of the baffle, and a limit plate is slidably connected to the inside of the support cavity. The inner end is communicated with the trachea, the No. 1 motor is arranged at the bottom end of the support cavity, the end of the No. 1 motor is connected with a ball screw, and the No. 2 motor is connected to the connecting plate through the sliding table. The top of the No. 1 motor is connected with a grinding head, and the device is also provided with an automatic air extraction component; the invention can reduce the scattering of the polished impurities on the side wall of the circuit board, reduce the pollution of the on-site environment, and at the same time make the polished circuit board It can be easily taken out, which improves the grinding efficiency of the circuit board.

Description

technical field [0001] The invention belongs to the technical field of grinding devices, in particular to a high-frequency and high-speed PCB grinding device with automatic cleaning function. Background technique [0002] PCB, also known as printed circuit board, is an important electronic component, a support body for electronic components, and a carrier for electrical interconnection of electronic components. The traditional deburring on the side surface of the PCB board is usually hand-held, which is inefficient and has a low degree of automation. Some structures can grind the fixed PCB board, but the grinding effect is not ideal, and the collection and processing of debris generated by grinding is relatively difficult. Trouble, need manual secondary cleaning. [0003] A Chinese patent with publication number CN210790327U discloses a deburring device for the side surface of waste PCB boards, including a workbench, a through hole, a first rotating shaft, a locking buckle,...

Problems solved by technology

[0004] However, when the grinding device in the above technology is grinding the side surface of the PCB circuit board, since the grinding structure and the side surface of the circuit board are directly exposed to the external environment, the impurities polished on the circuit board will fly around in a large area. It is difficult to be effectively recovered and cleaned by the pumping structure, which is easy to cause pollution to the processing site
