One clamping tooth is placed in the through slot at each end along the first direction, and two clamping teeth are placed in the remaining through slots. The two clamping teeth are respectively fixed to the bases of two grippers. When the clamping assembly clamps the electrode tab, the two clamping teeth in the through slot with two clamping teeth separate from each other and fit against the inner wall of the through slot along the first direction. When the clamping assembly is released, the two clamping teeth in the through slot with two clamping teeth fit against each other and are centered in the through slot.

[0036] Please refer to Figures 1 to 6 This application provides a battery tab shaping and detection device 100 for shaping and detecting the positive and negative tabs 201 of a battery 200. The battery tab shaping and detection device 100 includes a positioning mechanism 10 and a shaping mechanism. The positioning mechanism 10 carries the battery 200 and positions the positive and negative tabs 201 of the battery 200 respectively. The shaping mechanism includes a pressure head 21, a probe 22, and a driving assembly 23. The pressure head 21 corresponds to the positive and negative tabs 201 of the battery 200 respectively. The probe 22 is connected to the pressure head 21. The driving assembly 23 drives the pressure head 21 to press the tabs 201 of the battery 200 against the positioning mechanism 10 to shape the tabs 201, while simultaneously driving the probe 22 to conform to the tabs 201 for detection.

[0037] The battery tab shaping and testing device 100 provided in this application positions the positive and negative tabs 201 of the battery 200 respectively through the positioning mechanism 10; the shaping mechanism shapes the positive and negative tabs 201 and tests the positive and negative electrodes, reducing manual operation and improving the production efficiency of the battery 200.

[0038] In one feasible implementation, the positioning mechanism 10 includes a base plate and a first limiting member 12. The base plate is used to support the battery 200. The first limiting member 12 is disposed on the base plate and is used to space the positive electrode tab 201 and the negative electrode tab 201 of the battery 200 apart. In this way, the positive electrode tab 201 and the negative electrode tab 201 of the battery 200 are separated, avoiding a short circuit between the positive and negative terminals of the battery 200 during the positioning process, which could burn out the battery 200.

[0039] In one feasible implementation, the positive and negative electrode tabs 201 of the battery 200 are distributed along a first direction X. The base plate has a through-slot 111 extending vertically, and the through-slots 111 and the first limiting member 12 are spaced apart along the first direction X. The number of through-slots 111 is one more than the number of batteries 200, and the diameter of the through-slots 111 at both ends along the first direction X is smaller than the diameter of the through-slot 111 between them. The base plate also has a clamping assembly 13. The output end of the clamping assembly 13 abuts against the electrode tabs 201 of the battery 200 through the through-slots 111, fixing the electrode tabs 201 of the battery 200 between the first limiting member 12 and the output end of the clamping assembly 13. This fixation of the electrode tabs 201 of the battery 200 facilitates stability during shaping and improves the shaping effect of the electrode tabs 201. Simultaneously, this arrangement optimizes the overall structural volume of the device and facilitates observation and maintenance.

[0040] In one feasible implementation, the driving end of the clamping assembly 13 is a clamping drive member 131, and the output end is a gripper 132 assembly. The gripper 132 assembly has two grippers 132. Under the drive of the clamping drive member 131, the two grippers 132 move along the first direction X, approaching or moving away from the first limiting member 12, to respectively fix the positive electrode tab 201 and the negative electrode tab 201 of the battery 200. In this way, only one drive member is needed to drive the two grippers 132 to achieve separate positioning and fixing of the positive electrode tab 201 and the negative electrode tab 201 of the battery 200, saving costs and simplifying the structure and equipment.

[0041] In one feasible implementation, each gripper 132 includes a base 1321 and six gripping teeth 1322. One end of each gripping tooth 1322 extends through the through slot 111 in the vertical direction to grip the tab 201, and the other end is fixedly connected to the base 1321. The gripping teeth 1322 are sequentially fixed to the base 1321 along the first direction X, with adjacent gripping teeth 1322 being equidistant along the first direction X, and the gripping teeth 1322 on two grippers 132 being staggered.

[0042] In one feasible implementation, the battery tab shaping and detection device 100 provided in this application embodiment can support 6 batteries 200. The base plate has 7 through slots 111. One of the through slots 111 at both ends along the first direction X is provided with a clamping tooth 1322, and the other through slots 111 are provided with two clamping teeth 1322. The two clamping teeth 1322 are respectively fixed on the base 1321 of the two grippers 132.

[0043] When the clamping assembly 13 clamps the tab 201, the two clamping teeth 1322 in the through groove 111 with two clamping teeth 1322 separate from each other and fit against the inner wall of the through groove 111 along the first direction X; when the clamping assembly 13 is released, the two clamping teeth 1322 in the through groove 111 fit against each other and are centered in the through groove 111. In this way, the battery 200 can be easily placed and removed in the released state.

[0044] In one feasible implementation, the clamping drive 131 is a pneumatic finger cylinder. Pneumatic finger cylinders are characterized by high efficiency, reliability, economy, and strong adaptability, which is conducive to their widespread application.

[0045] In one feasible implementation, the positioning mechanism 10 includes six positioning components 14, each having a receiving groove 141 for accommodating the battery 200. Each positioning component 14 includes a second limiting member 142, disposed on the side of the battery 200 away from the tab 201 along the second direction Y. The second limiting member 142 is slidably connected to the base plate along the second direction Y, for limiting the battery 200 along the second direction Y. This allows for better positioning of the battery 200 and improves the throughput of the device. Furthermore, the second limiting member 142 can be driven by a limiting drive member, so that after the battery 200 is placed, it abuts against the battery 200 under the drive of the limiting drive member, thus fixing the battery 200.

[0046] In one feasible implementation, the clamping teeth 1322 are made of PEEK, and metal blocks are embedded in the portions of the clamping teeth 1322 that fit against the inner wall of the through hole and the tabs 201. This improves the wear resistance of the clamping teeth 1322 and extends the service life of the device.

[0047] In one feasible implementation, the shaping mechanism includes a base frame 101. The fixed end of the drive assembly 23 is fixedly connected to the base frame 101. The output end of the drive assembly 23 is provided with a movable connector 231. The movable connector 231 is slidably connected to the base frame 101 via a connector 232; the pressure head 21 includes two sub-pressure heads 21, each connected to the connector 232, and each sub-pressure head 21 has a through hole for accommodating the probe 22. This simplifies the structure of the device and improves the reliability of the detection.

[0048] In one feasible implementation, the battery tab shaping and testing device 100 further includes a transfer mechanism. The positioning mechanism 10 is located at the output end of the transfer mechanism. The transfer mechanism is used to move the positioning mechanism 10 below or out of the shaping mechanism. When the positioning mechanism 10 is located below the shaping mechanism, the pressure head 21 is opposite to the positive and negative tabs 201 of the battery 200. Further, the transfer mechanism 30 can be a linear module or a transfer mechanism 30 such as a conveyor belt.

[0049] In one feasible implementation, the battery tab shaping and detection device 100 of this application can also be equipped with an unloaded detection sensor, which can detect whether there is an unloaded state to prevent adverse effects on the positive and negative electrode detection results.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
