OCV Sorting and Testing Machine For Prismatic Battery Production

1、 Equipment introduction

1. Equipment application

This equipment is designed to test the internal resistance and voltage of prismatic battery and conduct manual sorting after PLC automatically judges the sorting grade, and scan the code to read the capacity; Test the side voltage; Test the thickness of the electric core; And connect all data to MES system. The fixture is manually placed on the mobile fixture, and after the battery is placed, click the duplex control button with both hands, and the fixture will automatically move to the preloading position to complete the inspection process. Finally, it will be manually taken and manually operated in a reciprocating cycle, Continuous production can be realized (the test function includes code scanning and reading capacity; test voltage and internal resistance and record them in the QR code; test edge voltage to distinguish ng; secondary test OCV and software to distinguish; cell thickness measurement and upload to the corresponding bar code; all data are uploaded to the MES system).

2. Equipment structure

It is composed of manual operation platform / voltage testing mechanism / internal resistance testing mechanism / code scanning testing mechanism / side voltage testing mechanism / main control mechanism and other devices.

3. Equipment action process

Manually put the battery on the feeding test bench, and automatically enter the test station through the platform to test the voltage, internal resistance and code scanning; The thickness measuring mechanism presses down to measure the thickness; After the detection, the PLC sorts according to the preset sorting conditions and the indicator light is turned on. The edge voltage test needle interlocks to puncture the aluminum film and test the positive and negative electrode ears; Finally, manually classify the batteries according to the test data.

4. Software functions

1) Language: Simplified Chinese;

2) Scanning QR code reading capacity; Accurately read the voltage / internal resistance stored by the battery in the database.

Process editing and management functions:

3) Process editing and management functions:

a. Three parameter gear detection can be set, and different values can be selected according to the set gear;

b. The tested data files can be saved in the computer, and RS232C interface can be equipped for remote control and data acquisition and analysis.
