PCB assembling device

Abstract

The invention discloses a PCB assembling device which comprises a PLC control system, an RFID system, a pneumatic clamping jaw for clamping a PCB, double shafts, a clamping jaw air cylinder, an up-and-down air cylinder (4) for locating the PCB, a horizontal air cylinder and a pressing fit mechanism matched with the up-and-down air cylinder (4) to be in press fit with the PCB. One end of the clamping jaw air cylinder is fixedly connected to the double shafts, the other end of the clamping jaw air cylinder is fixedly connected with the pneumatic clamping jaw, and the RFID system, the pneumatic clamping jaw, the double shafts, the up-and-down air cylinder (4), the horizontal air cylinder, the clamping jaw air cylinder and the pressing fit mechanism are connected with the PLC control system through circuits. By means of the PCB assembling device, automatic assembling of the PCB can be achieved, the assembly position accuracy is high, and the assembling speed is high; the quality of the PCB and an outer shell can be automatically judged, and an operator can be informed of problems in any link and can be informed of specific conditions; force of PCB pressing fit can be adjustable. By means of the control mode, the production efficiency is greatly improved, the production cost is saved, the manual error operation is reduced, and the PCB assembling device is quite convenient to use.

Description

technical field [0001] The invention relates to the field of industrial control automation, in particular to an automatic assembly device for assembling a PCB circuit board on an equipment casing. Background technique [0002] With the development of industry and the advancement of technology, PCB (Printed Circuit Board) has become the most active industry in the contemporary electronic component industry, and its application in modern industry is becoming more and more extensive. PCB, which is called printed circuit board in Chinese, is an important electronic component that is printed and spatially configured for the purpose of installing electronic components. Surface Mount Technology (SMT) is a circuit assembly technology that mounts non-lead or short-lead surface mount components on the surface of a PCB, and solders and assembles them by reflow soldering or dip soldering. The prerequisite for the implementation of circuit assembly and connection technology is to positi...

AI Technical Summary

Problems solved by technology

However, this kind of PCB fixture still needs manual force to assist in installing the PCB, which is a waste of time and manpower, and the pressure cannot be adjusted

Using the second method is very difficult for manual operations, and long-term operations can easily lead to personnel fatigue. At the same time, direct contact with PCBs is likely to generate static electricity and increase the probability of product scrapping

Moreover, there is no detection device in the installation process, and it is often found in the inspection after the installation that it cannot be used after the installation is completed due to poor PCB or poor casing, resulting in waste.
