[0021] As shown in the figure, a square cylindrical battery OCV test device includes a code scanning component, a transmission component and a test component. The transmission component includes a feed pull position 1, a qualified pull position 2 and an unqualified pull position, and the feed pull position 1, the qualified pull position 2 and the unqualified pull position are all provided with a clamp 13, and the unqualified pull position includes a voltage test unqualified pull position 3, an internal resistance test unqualified pull position 4 and a weight unqualified pull position 5.

[0022] The transmission assembly also includes a manipulator corresponding to the fixture 13, and the manipulator is electrically connected to the tester body.

There are two clamps 7, and the linear module 6 is a T-shaped structure, which enables the simultaneous detection of two batteries, further improving work efficiency.

[0023] The code scanning component is arranged at the starting end of the feeding pull position 1, and the code scanning component includes a code scanning gun 10, and the code scanning gun 10 is electrically connected to the tester body.

[0024] The test assembly includes a balance 11, a tester body (not marked in the figure) and a probe 12.

The upper and lower sides of the feed pull station 1 are both provided with a fixedly connected driving cylinder 14, and the piston end of the driving cylinder 14 is fixedly connected to the probe 12.

[0025] In actual use, the specific steps are as follows:

[0026] The batteries to be tested are manually placed on the clamp 13 at the starting end of the feed pull position 1, and the barcode scanner 10 scans the barcode on the surface of each battery to be tested in turn and uploads its identity information to the control display; when the batteries to be tested are transmitted to the terminal of the feed pull position 1, the clamp 7 grabs two batteries at the same time, and then the rotating table 9 drives the clamp 7 to rotate 90° and move downward to the balance 11, the clamp 7 releases the battery, determines whether the battery weight is qualified, and transmits the result information to the control display.

[0027] If both batteries are qualified in weight, the clamp 7 grabs the battery again, moves two unit lengths along the Y-axis direction to the probe 12 area, and drives the cylinder 14 to drive the probe 12 to fit the upper and lower ends of the battery to determine whether the battery voltage and internal resistance are qualified, and transmit the result information to the control display; then the probe 12 is reset and the clamp 7 moves one unit length in the opposite direction along the Y-axis; then according to the control display, if it is determined that the battery voltage and internal resistance are qualified, the clamp 7 moves four unit lengths along the X-axis direction to the starting end of the qualified pull position 2, and the rotating table 9 drives the clamp 7 to rotate 90° in the opposite direction, move downward to the fixture 13 of the qualified pull position 2 and flow out, thus completing the test.

[0028] If the control display determines that the battery is of unqualified weight, the clamp 7 grabs the battery again, moves a unit length along the Y-axis direction and a unit length along the X-axis direction to the starting end of the unqualified weight pulling position 5, and the rotating table 9 drives the clamp 7 to rotate 90° in the opposite direction, move downward to the clamp 13 and flow out.

[0029] If the control display determines that the battery is of unqualified voltage / unqualified internal resistance, the probe 12 is reset, the clamp 7 moves one unit length in the opposite direction along the Y-axis direction, and moves two / three unit lengths in the X-axis direction to the starting end of the voltage test unqualified pull position 3 / internal resistance test unqualified pull position 4, and the rotating table 9 drives the clamp 7 to rotate 90° in the opposite direction, move downward to the fixture 13 and flow out.
