Through the computer related software to the image processing and automatic analysis and judgment. Identify good and bad products, and pick out the bad products, the front and rear end of the equipment can be connected with the production line.
1.3 equipment operation flow:
1.3.1 the main logistics line of the customer is divided into two pull-in materials, which are transported to the test area through the conveyor belt; Accurately locate the test location through the positioning mechanism of the test point in the test area;
1.3.2 carry out automatic inspection and judgment through computer related software. The discharging end is automatically sorted out defective products by a mechanical hand and placed in the designated position. The OK battery flows away through the assembly line.
1.3.3 the incoming material of the product is fed with A/B, and the feeding manipulator grabs two pallets (one A and one B) at A time to pull the belt of the equipment. After the detection is completed, the feeding manipulator grabs two pallets at A time and drops the material at the same time. Each pallet is a single cell, and the overall size is one.
1.3.4 the X-ray layout is u-shaped, and the connection between the upper and lower materials with the main pull belt is the manipulator, while the upper and lower materials manipulator is designed and produced by the professional technology.
1.3.5 with qr code reading function, scanning gun sr-751; Bind with all measurements and pictures, save in Excel format.
1.3.6 NG product unified collection (pallet and battery) shall be manually taken out and placed in the designated position, and at least 6 pieces shall be stored.
1.3.7 the feeding direction of the production line is from right to left, and the battery pole ear is perpendicular to the customer's main logistics line.

1.5.4 PC for control and image processing software, measurement and judgment software.
1.5.5 radiation-proof sheet metal, detection system, conveyor belt, sorting manipulator, NG cache device, loading and unloading manipulator.
Ii. Incoming materials and product specifications suitable for the equipment:
2.1 testable cell specifications:
| Height of the battery | 148mm |
| The width of the battery | 100-200mm |
| The thickness of the battery | 15mm |
2.2 inspection method: automatically check and determine the GAP between the cathode and anode on the upper and lower part of the bare cell (negative electrode package positive electrode).
2.2.1 test the four corners of the cell, at the four corners of A, B, C and D of the bare cell.
2.2.2 the displacement distance between the angular cathode and the anode of the bare cell can be detected, and the data between each layer can be output on the display and the maximum, minimum and average values can be statistically analyzed. The number of inspection object layers (ROI) can be set according to the requirements, the maximum is 40 layers (iron lithium material ≤ 40 layers, three material ≤ 30 layers; Take the sample provided by the buyer as the reference standard.
2.3 operation mode: automatic measurement, automatic judgment of good and bad products according to the prescribed standards, and automatic sorting of bad products.
Iii. Equipment inspection capability
3.1 determination accuracy: repetition accuracy S=±60 m or less (measured in standard tablets).
3.2 check mode
3.2.1 full automatic: the battery shall be automatically supplied and transported for automatic inspection, and the OK and defective products shall be automatically separated and discharged according to the result determined by the procedure according to different undesirable categories.
3.2.2 semi-automatic: automatic inspection shall be conducted for the automatic supply and delivery of batteries. However, the inspection shall determine the following treatment methods:
< semi-automatic 1> OK/NG by manual determination, no manual intervention (determination), the equipment in standby state;
< semi-automatic 2> OK/NG machine automatic recognition. When determining OK or NG, the machine can set standby for manual intervention, standby time optional (minimum 1 second, maximum unlimited). In standby mode, if there is no manual intervention, the machine will automatically process according to the judgment result.
