Mechanism Module Functions——OCV test sorting
Module function introduction:
This module mainly uses high-precision testing instruments to complete the classification and data recording of the voltage internal resistance test of the square shell cell Through manual picking and loading, the belt transports the batteries to the area to be tested. First, a high-definition identification code reader reads the identity code of the battery, and then completes the OCV test and matches the data with the battery code to save or transmit. The test value is within the range The batteries are picked up by the manipulator and transported to different gears to flow out. If the test exceeds the set value, they will be moved to the NG channel. When the OK channel is full of 8 batteries, they will be loaded into the buffer box by the manipulator, and the belt conveyor will be sent to the adhesive. Stacking position to complete the next process
Functional advantages:
1. The condition value of test parameters can be set on the man-machine interface.
2. The probe adopts nickel-plated probe assembly, and the four-wire method is used for testing. The probe is cylindrical and the bottom of the probe is sharp, which can be well adapted to ensure Contact, nickel-plated probe process, greatly reduces impedance, improves test accuracy.
3. The battery performance data of the system test implements the database management mode, long-term storage, strong traceability, with the data analysis function of the software, the product Conduct long-term monitoring and analysis of performance and quality to guide the improvement of R&D formulas and improve the production process.
4. The mechanical gripper is designed to prevent slipping and pinching. Effectively protect the battery cells,
5. Prevent mistaking and matching groups due to personnel mistakes, increase the frame buffer design to prevent fooling,
6. The equipment is easy to operate, convenient to debug, and stable in performance.

Module Functions——Polarity visual detection
Main functions of the equipment:
The battery module CCD polarity detection is mainly applicable to-the fatigue and negligence of the battery module during the manual stacking process leads to the wrong arrangement of the positive and negative electrodes, which causes a short circuit of the module, which brings unnecessary safety hazards and economic losses; the equipment in this section The Mark feature points of the cell poles are identified by taking photos with the camera a, and the visual software calculates and compares whether the stacking arrangement is wrong. When the detection triggers an arrangement err ror alarm, the release is confirmed manually on site and discharged to a bad grade.
Equipment advantage:
Visual inspection of repetitive work can effectively avoid the occurrence and outflow of defects caused by personnel fatigue and negligence, and discharge them in time before wo elding to reduce the cost of rework after welding
