[0014] Furthermore, the step S3 is specifically as follows:

[0015] The industrial computer automatically compares the polarity arrangement order and arrangement position of the battery cell transmission diagram and the battery cell arrangement diagram through an artificial intelligence algorithm to see whether they are consistent. If so, a judgment result of passing the battery cell polarity judgment is generated; if not, a judgment result of failing the battery cell polarity judgment is generated, and the row and column position of the incorrect battery cell is carried.

[0037] The embodiments of the present application provide a method, system, device and medium for automatically determining the polarity of a battery cell, thereby improving the efficiency and reliability of determining the polarity of a battery cell and reducing the cost of determining the polarity of a battery cell.

[0038] The technical solution in the embodiments of the present application has the following overall idea: a cell transmission diagram is captured by a line scan camera, and the cell transmission diagram is compared with a standard cell arrangement diagram through an artificial intelligence algorithm, and the cell polarity is automatically determined through image detection to improve the efficiency and reliability of cell polarity determination and reduce the cost of cell polarity determination.

[0039] Example 1

[0040] This embodiment provides a method for automatically determining the polarity of a battery cell. Figure 1 、 5 As shown, the following steps are included:

[0041] Step S1: The industrial computer stores a cell layout diagram in advance. The PLC (programmable logic controller) drives a conveyor belt to transport the tray loaded with cells via a motor based on a transmission instruction sent by the industrial computer. The PLC controls the operation of the motor based on the TCP / IP protocol.

[0042] Step S2: After the industrial computer senses that the battery cell has been transferred to the right position through the encoder, the industrial computer uses a line scan camera to capture a battery cell transmission diagram of the battery cell on the conveyor belt; the line scan camera sends the battery cell transmission diagram to the industrial computer based on the TCP / IP protocol;

[0043] Step S3: The industrial computer automatically determines the polarity of the battery cells based on the battery cell transmission diagram using the battery cell arrangement diagram, generates a determination result, and displays it on a human-machine interface;

[0044] Step S4: The industrial computer sends a sorting instruction to the PLC based on the judgment result. The PLC controls the robotic arm to sort the battery cells transmitted on the conveyor belt based on the received sorting instruction.

[0045] When the polarity arrangement of the battery cells changes, it is only necessary to update the battery cell arrangement diagram, which greatly improves the flexibility of battery cell polarity judgment.

[0046] In step S1, the battery cell arrangement diagram is a top view of the battery cells correctly arranged in the tray; the positive electrode pole and the negative electrode pole of the battery cells are respectively at the top and bottom ends.

[0047] The step S2 is specifically as follows:

[0048] After the industrial computer detects the battery cell's arrival via an encoder, it activates a light source to illuminate the cell. A line scan camera then captures the cell's movement from top to bottom on the conveyor belt. This light source significantly enhances the clarity of the line scan camera's image, thereby ensuring accurate polarity determination. The encoder provides feedback on the conveyor belt's speed and distance.

[0049] The step S3 is specifically as follows:

[0050] The industrial computer automatically compares the polarity arrangement order and arrangement position of the battery cell transmission diagram and the battery cell arrangement diagram through an artificial intelligence algorithm to see whether they are consistent. If so, a judgment result of passing the battery cell polarity judgment is generated; if not, a judgment result of failing the battery cell polarity judgment is generated, and the row and column position of the incorrect battery cell is carried.

The PLC (programmable logic controller) drives the conveyor belt driven by the motor to transport the pallets loaded with battery cells based on the transmission instructions sent by the industrial computer. The PLC controls the operation of the motor based on the TCP / IP protocol.

[0054] The cell capture module is used to capture a cell transmission diagram of the cells on the conveyor belt using a line scan camera after the industrial computer senses that the cells have been transferred to their proper locations using an encoder. The line scan camera then sends the cell transmission diagram to the industrial computer based on the TCP / IP protocol.

[0055] A polarity judgment module is used for the industrial computer to automatically judge the polarity of the battery cell based on the battery cell arrangement diagram and the battery cell transmission diagram, generate a judgment result and display it on the human-machine interface;

[0056] The battery cell sorting module is used for the industrial computer to send a sorting instruction to the PLC based on the judgment result, and the PLC controls the robotic arm to sort the battery cells transmitted on the conveyor belt based on the received sorting instruction.

[0057] When the polarity arrangement of the battery cells changes, it is only necessary to update the battery cell arrangement diagram, which greatly improves the flexibility of battery cell polarity judgment.

[0058] In the battery cell transmission module, the battery cell arrangement diagram is a top view of the battery cells correctly arranged in the tray; the positive pole and negative pole of the battery cells are at the top and bottom respectively.

[0059] The battery cell shooting module is specifically used for:

[0060] After the industrial computer detects the battery cell's arrival via an encoder, it activates a light source to illuminate the cell. A line scan camera then captures the cell's movement from top to bottom on the conveyor belt. This light source significantly enhances the clarity of the line scan camera's image, thereby ensuring accurate polarity determination. The encoder provides feedback on the conveyor belt's speed and distance.

[0061] The polarity judgment module is specifically used for:
