Longitudinal moving type PCB board grinding device

Abstract

The invention discloses a longitudinal moving type PCB board grinding device which comprises a base, an X-axis feeding mechanism, a carrying die, a door frame, an air cylinder, a guide rod, a supporting plate, a square pipe, a first support, a rack, a rotating shaft, a servo motor, a gear, a second support, a speed adjusting motor and a board grinding mechanism. A PCB is placed in the carrying die. The air cylinder moves downwards to push a template mechanism to make contact with the PCB. The speed adjusting motor works to drive the board grinding mechanism to conduct board grinding treatment on the PCB. The servo motor works to drive the rotating shaft to rotate, and therefore the gear is driven to rotate. Due to the fact that the gear is engaged with the rack, the servo motor can drive the board grinding mechanism to move longitudinally. Meanwhile, the X-axis feeding mechanism can drive the PCB placed in the carrying die to move transversely, and therefore automatic board grinding can be conducted on the PCB. The longitudinal moving type PCB board grinding device is simple in structure and capable of automatically conducting board grinding treatment on the PCB, meanwhile, abrasive materials make even contact with the PCB, board grinding is even and continuous, and the automation degree is high. Meanwhile, integrated design is adopted, and the cost is effectively reduced.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a vertically traveling PCB board grinding device. Background technique [0002] Printed circuit board, also known as PCB board, is the support body of electronic components and the carrier of electrical connection of electronic components. The manufacturing process of PCB board is complicated. Before covering with green oil, surface treatment must be carried out, and surface treatment is usually There are two kinds, one is physical grinding plate and the other is chemical grinding plate. [0003] A. Physical grinding plate: Physical grinding plate is generally polished and roughened by grinding wheel and volcanic ash. The basic principle is to use volcanic ash as an abrasive to grind the PCB board with the aid of high-speed rotation of the grinding wheel, to remove impurities and oxides on the copper surface, and to increase the bonding force between the copper board and the green oil. ...

AI Technical Summary

Problems solved by technology

[0005] Because the solution after the chemical grinding plate reaction is easy to cause environmental pollution, many manufacturers use physical grinding plates, but the length of the grinding wheel of the existing physical grinding plate equipment is long, and it is difficult to evenly contact the abrasive with the PCB board. As a result, the effect of grinding the board is poor. At the same time, due to the presence of some coarse abrasives, the copper layer of the PCB board is prone to damage.
