A charging pile main controller assembly device

Abstract

The invention discloses an assembly device for a main controller of a charging pile, comprising: a process-assembly unit used for assembling the main controller unit and a sensor unit, and a process-one assembly unit arranged on the process-1 assembly unit for assembling an arc sensor and an arc protection main unit The assembly unit in process two is elastically supported on the assembly unit in process two, and is used to simultaneously insert the arc protector and the microcontroller into the PCB circuit board and the connection terminal correspondingly, and the pressing unit in process three. The present invention can realize the completion of multiple processes at one station, and does not need to switch stations back and forth to use different tooling. When assembling the main controller of charging piles in batches, the assembly device of the present invention can greatly improve work efficiency.

Description

Technical field: [0001] The invention relates to an assembling device for a main controller of a charging pile. Background technique: [0002] Controller structure description: [0003] The structure of a common controller in the new energy vehicle charging pile is as follows: figure 1 and 2 As shown, it includes two parts, namely, a main controller unit 400 and a sensor unit 500 , and the main controller unit 400 includes a connection terminal 401 and a microcontroller 402 . [0004] The sensor unit 500 is composed of a PCB circuit board 501 and various circuits or sensor control units integrated or plugged on the PCB circuit board 501. The sensor control units include leakage protection, voltage detection, emergency stop detection, and relay control. , temperature detection, current detection, arc protector, etc., wherein the arc protector is composed of an arc sensor 600 and an arc protection main unit 601, such as image 3 . [0005] The connection terminal 401 is c...

AI Technical Summary

Problems solved by technology

When assembling, the existing practice is to set up a variety of tooling, the assembly of the arc protector uses a set of tooling, the assembly of the main controller unit 400 and the sensor unit 500 uses a set of tooling, and the assembly of the sensor unit 500 uses a set of tooling, so the assembly At least three separate toolings are required, resulting in low assembly efficiency

[0008] In addition, when the arc sensor 600, the arc protection main unit 601, and the pin 700 on the microcontroller 402 are plugged into the corresponding ports, in order to ensure the fastening effect of the connection, conductive glue is applied at the corresponding joint position. After the plug-in assembly, a holding tool is needed to press the whole structure tightly to ensure the bonding stability of the glued part, so a fixture tool is also needed, which will increase the cost

In addition, the pins 700 on the corresponding components are relatively fragile, and moving back and forth can easily cause the pins to bend and break, which will affect the plugging effect of the product
