Example 2

Referring to Figures 1 to 8, based on Example 1, in this embodiment, two support frames 33 are provided on the work surface 32, each independently carrying the battery cells; at the loading station 100, two groups of adjustment mechanisms 7 are also provided, and the adjustment mechanisms 7 are correspondingly arranged under the support frames 33, respectively used to adjust the position of the battery cells.

Mechanism 74 is used to drive the support table 77 to move horizontally along the Y-axis direction; the X-axis adjustment structure 73 is connected to the support table 77, and the X-axis adjustment mechanism 73 is used to drive the support table 77 to move horizontally along the X-axis direction. A visual inspection camera is also provided, which takes photos of the two battery cells for inspection.

Example 3

See Figures 1 to 8. On the basis of Example 1 or Example 2, the utility model also includes: a patch transfer mechanism 6, the patch transfer mechanism 6 includes two transmission guide rails 65 arranged side by side, and a transverse movement component located above the transmission guide rails 65, and the transmission direction of the transmission guide rails 65 intersects with the moving direction of the transverse movement component; the transmission guide rails 65 are arranged corresponding to the first transmission line 11, and are used to transfer the battery cells from the patch transfer mechanism 6 to the first transmission mechanism 1.

The lateral movement assembly includes a transfer patch suction cup 64 and a transfer motor 61. The transfer motor 61 drives the transfer patch suction cup 64 to move so as to pick up and place the battery sheet on the transmission rail 65. The transfer motor 61 is connected to the transfer module 62, the transfer module 62 is connected to the rotating motor 63, the rotating motor 63 is connected to the transfer patch suction cup 64, and the transmission rail 65 is also equipped with a sensor 66. One end of the transmission rail 65 is arranged corresponding to the first transmission line 11, and the other end is arranged corresponding to the loading rail (not shown in the figure). The loading rail (also includes two transmission lines, each of which transmits a battery cell) transmits the battery cell to the transmission rail 65, and the transmission rail 65 then transmits the battery cell to the first transmission line 11. When the loading rail transmits two battery cells to the transmission rail 65 at the same time, when the sensor 66 on the transmission rail 65 senses the battery cell, the transverse movement module maintains the current position state and does not move. When the loading rail transmits a battery cell (at this time, there is no battery cell on the other transmission line of the loading rail), the battery cell is transferred to the transmission rail 65. When the battery is transferred to the transmission rail 65, the sensor 66 on one of the transmission rails 65 cannot sense the battery cell, and the transverse movement module will move to the top of the battery cell to absorb the battery cell. The loading rail continues to transfer the battery cell to the transmission rail 65. Under normal circumstances, two battery cells are transferred. When only one battery cell is transferred to the transmission rail 65 again, the transverse movement module drives the battery cell adsorbed on the suction cup 64 to move to the transmission rail 65 where no battery cell is placed. At this time, both transmission rails 65 are placed with battery cells, and the two transmission rails 65 simultaneously transfer the two battery cells to the first transmission line 11. The transfer module 62 can be displaced horizontally and vertically, and the rotary motor 63 can be used to rotate the battery cell so that it is correctly placed on the transmission rail 65 where no battery cell is placed. That is, the battery cell needs to be transferred by the transfer module 62 and the rotary motor 63 needs to be rotated to ensure that the chamfer position of the battery cell remains consistent. By setting a transfer and patch mechanism, the battery cells on the first transmission line 11 can be replenished in time to achieve simultaneous testing of two battery cells.

This embodiment also includes: a detection mechanism 8, located at the test station 200, the detection mechanism 8 includes an upper probe row 81 and a lower probe row 82 arranged in parallel, the work table 32 is located between the upper probe row 81 and the lower probe row 82, and two groups of probes 83 arranged discontinuously are respectively provided on the upper probe row 81 and the lower probe row 82, and two groups of probes 83 are respectively provided on the probe row 81 and the lower probe row 82, with a gap between the two groups of probes, and the size of the gap is consistent with the size of the gap between the two battery cells, and are respectively used to detect the two battery cells.

Specifically, as shown in FIG. 7 , the detection mechanism 8 includes two support seats 84 disposed opposite to each other. The vertical lifting device 85, the upper probe row support frame 86 and the lower probe row support frame 87 are arranged in parallel and located between the two support seats 84, and are connected to the vertical lifting device 85. The upper probe row support frame 86 is used to place the upper probe row 81, and the lower probe row support frame 87 is used to install the lower probe row 82. The vertical lifting device 85 is used to drive the upper probe row support frame 86 and the lower probe row support frame 87 to move relative to or away from each other, so as to drive the upper probe row 81 and the lower probe row 82 to approach each other or move away from each other. The work table 32 is located between the upper probe row support frame 86 and the lower probe row support frame 87, that is, between the upper probe row 81 and the lower probe row 82. Two battery cells are placed on the work table 32 to realize simultaneous detection of the two battery cells.
