[0002] During battery production, it is necessary to test the battery's edge voltage. When testing the battery's edge voltage, it is necessary to first puncture both sides of the battery's top seal to test whether it is energized. If the circuit is conductive, the battery's edge voltage is then tested with the help of a test fixture. This testing method is inefficient and wastes labor. Moreover, the current battery production trend is multi-station processing and fully automated production, and this semi-automatic testing method cannot be applied thereto. Summary of the Invention

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] like Figure 1 As shown, the front end of the battery 100 has a top sealing edge 102 and two tabs 101 .

[0017] like Figure 2-4As shown, a side voltage detection mechanism includes a third stand 71, a second tab support assembly 72, a pressing assembly 73 and a top edge sealing assembly 74; the second tab support assembly 72 is installed at the lower part of the third stand 71 to support a tab of the battery; the second tab support assembly 72 includes a second base body 721, a second support block 722 and a second support block driving cylinder 723; the second support block driving cylinder 723 is fixed to the third stand 71 through the second base body 721; the second support block 722 is installed at the power output end of the second support block driving cylinder 723; the pressing assembly 73 includes a third pressing block 731 correspondingly arranged above the second tab support assembly 72 and an installation The third pressing block driving device 732 drives the third pressing block 731 to move up and down on the third stand 71; the top cutting and edge sealing assembly 74 includes a Y-axis pushing assembly 741, a Z-axis pushing assembly 742 and two groups of cutter assemblies 743 with the same structure; the two groups of cutter assemblies 743 are arranged between the second tab support assembly 72 and the pressing assembly 73 and are symmetrically arranged on the left and right; the Y-axis pushing assembly 741 is installed on the third stand 71 to drive the Z-axis driving assembly to move forward and backward; the Z-axis driving assembly drives the two groups of cutter assemblies 743 to move up and down; the edge voltage detection mechanism is used as a processing station on the multi-station turntable to perform edge voltage detection on the battery, and the two groups of cutter assemblies 743 have cutters 743 3. The two cutters 7433 and the third pressure block 731 control the conduction and disconnection of the circuit through a relay. The two cutters 7433 are connected to the current detection element through wires to detect whether the battery circuit is connected. The cutter 7433 and the third pressure block 731 on the side away from the positive ear are connected to the voltage detection element through wires to detect the edge voltage. During processing, the positive ear of the battery is first supported by the second ear support assembly 72, and the third pressure block driving cylinder 7321 then drives the pressure block down to press on the positive ear. The Y-axis pushing assembly 741 drives the Z-axis driving assembly to move forward, so that the cutter 7433 on the cutter assembly 743 contacts the front end of the top sealing edge, and then the cutter assembly is driven by the Z-axis pushing assembly 742. Component 743 moves downward to cut the top edge seal. The relay controls the two cutters 7433 to be energized and detects whether the circuit is conductive. If so, the relay controls the cutter 7433 near the positive ear to be powered off and controls the third pressing block 731 to be energized to detect the edge voltage of the battery. If the edge voltage is within the set range, it is OK. If it is not within the range, it is NG. Batteries with NG edge voltage will not be processed subsequently. If the detected circuit is not conductive, the top edge seal component 74 is reset and the cutting is repeated. After it is conductive, the edge voltage is detected again. If there is no conduction for three consecutive cuts, it is also judged that the edge voltage is NG. The battery will not be processed subsequently and will be unloaded and classified through the unloading and classification mechanism.

In the original state, the slider 7323 is in contact with the limiting boss 7322-1, and the third pressure block drives the cylinder 7321 to drive the mounting block 7322 to move downward. When the third pressure block 731 is in contact with the positive ear of the battery, the second mounting seat 7326 moves upward, the slider 7323 slides upward, and the fourth spring 7325 is compressed, thereby playing a buffering role to prevent the ear from being crushed.
