[0030] As shown in Figures 1 to 3 The positioning device for tab includes a first base, a second base 10, a positioning clamp 20, a driving mechanism 30 and a detection mechanism 40, wherein the positioning clamp 20 is rotatably arranged on the first base, the positioning clamp 20 has a positioning groove 21, the positioning groove 21 is used for accommodating the core to be positioned; the driving mechanism 30 is movably arranged on the second base 10, the driving mechanism 30 has a driving end, the driving end is drivingly connected with the positioning clamp 20, so as to drive the positioning clamp 20 to rotate and drive the core to be positioned to rotate; the detection mechanism 40 is arranged on the second base 10, the detection mechanism 40 has a detection end, the detection end is used for detecting whether the tab of the core to be positioned is adjusted in place.

[0031] The positioning clamp 20 is driven to rotate by the driving end of the driving mechanism 30, so as to drive the to-be-positioned winding core to rotate. In the process of rotating, the tab on the to-be-positioned winding core is driven to rotate to the adjusted position. The detection end of the detection mechanism 40 detects whether the tab of the to-be-positioned winding core is adjusted to the position, so as to realize automatic alignment of the tab, without manual alignment. The alignment of the detection mechanism 40 is more accurate than manual alignment, so as to ensure the connection reliability of the tab and the upper cover, ensure the qualified rate of the winding core, and realize mass production of the button cell.

[0032] It should be noted that, in the present application, the profile line of the groove wall surface of the positioning groove 21 is matched with the profile line of the outer circumferential surface of the to-be-positioned winding core. In this way, after the to-be-positioned winding core is positioned in the positioning groove 21, the to-be-positioned winding core will not shake when the positioning clamp 20 rotates with the driving end of the driving mechanism 30, so as to ensure the adjustment reliability and accuracy of the tab.

[0033] As shown in Figures 1 to 3 , the driving mechanism 30 includes a first support plate 31, a first driving part 32, and a disc structure 33. The first support plate 31 is arranged on the second base 10. The first driving part 32 is arranged on the first support plate 31 and has a first driving shaft. The first driving shaft is drivingly connected with the disc structure 33. The positioning clamp 20 is in a columnar structure, and the axial end surface of the positioning clamp 20 has a positioning groove 21. The outer circumferential surface of the disc structure 33 serves as a driving end and drivingly cooperates with the outer circumferential surface of the positioning clamp 20. The disc structure 33 rotates to drive the positioning clamp 20 to rotate. In this way, by arranging the driving mechanism 30 in the form of the first support plate 31, the first driving part 32, and the disc structure 33, the fixing reliability of the driving mechanism 30 is ensured, and the driving reliability of the driving mechanism 30 to the positioning clamp 20 is ensured.

[0034] As shown in Figure 1 , the disc structure 33 includes a disc body 331 and an elastic ring 332. The first driving shaft is drivingly connected with the disc body 331. The elastic ring 332 is sleeved on the outer circumferential side of the disc body 331 to form a driving end, so as to increase the friction force between the outer circumferential surface of the disc structure 33 and the outer circumferential surface of the positioning clamp 20. In this way, by arranging the disc structure 33 in the form of the disc body 331 and the elastic ring 332, the disc body 331 is connected with the first driving shaft, the driving reliability of the first driving shaft to the disc body 331 is ensured, the elastic ring 332 is sleeved on the outer circumferential side of the disc body 331, which is conducive to increasing the friction force between the outer circumferential surface of the disc structure 33 and the outer circumferential surface of the positioning clamp 20, and the positioning clamp 20 is driven to rotate by the friction force between the two.

[0035] As shown in Figure 1 and Figure 3As shown, the first support plate 31 is slidably arranged on the second base 10, and the driving mechanism 30 further comprises a second driving part 34 arranged on the second base 10, and a second driving shaft of the second driving part 34 is drivingly connected with the first support plate 31. The first support plate 31 has a working position at which the first support plate 31 moves towards the first base so that the outer circumferential surface of the disc body structure 33 cooperates with the outer circumferential surface of the positioning clamp 20, and the first support plate 31 has a avoiding position at which the first support plate 31 moves away from the first base so that the outer circumferential surface of the disc body structure 33 is disengaged from the outer circumferential surface of the positioning clamp 20. In this way, it is ensured that the disc body structure 33 does not interfere with the subsequent welding operation of the tab and the upper cover plate after the tab alignment operation is completed, thereby ensuring the normal progress of the subsequent welding operation.

[0036] It should be noted that in the present application, the positioning device further comprises a control module, the control module is signal connected with the detection mechanism 40, the control module is control connected with the first driving part 32, and the control module is control connected with the second driving part 34; the control module controls the first driving part 32 and / or the second driving part 34 to act according to the detection signal obtained by the detection mechanism 40; wherein when the detection signal is that the tab is not adjusted in place, the control module controls the first driving part 32 to drive the disc body structure 33 to rotate along the preset direction and drive the to-be-positioned roll core to rotate, so as to adjust the position of the tab until the tab is adjusted in place; when the detection signal is that the tab is adjusted in place, the control module controls the second driving part 34 to drive the first support plate 31 to move away from the side of the first base, so that the disc body structure 33 is in the avoiding position. In this way, the automation degree of the positioning device is greatly improved.

[0037] It should be noted that in the present application, as Figure 1 shown, the first driving shaft of the first driving part 32 extends in the vertical direction, and the second driving shaft of the second driving part 34 extends in the horizontal direction to drive the first support plate 31 to be slidably arranged in the horizontal direction. In this way, the rotation and horizontal sliding reliability of the disc body structure 33 is ensured.

[0038] It should be noted that in an embodiment of the present application which is not shown in the figure, the first driving shaft of the first driving part 32 extends in the vertical direction, and the second driving shaft of the second driving part 34 extends in the vertical direction and drives the first support plate 31 to be vertically arranged. In this way, the rotation reliability and lifting reliability of the disc body structure 33 is ensured.

[0039] As Figure 1 and Figure 2As shown, the positioning device further comprises a stop clamp 50, which is arranged on the first base and has a stop end with a stop surface matched with the partial outer circumferential surface of the positioning clamp 20; the positioning clamp 20 is located between the stop clamp 50 and the disc structure 33 of the driving mechanism 30, and the outer circumferential surface of the positioning clamp 20 is in external tangential contact with the outer circumferential surface of the disc structure 33, and the outer circumferential surface of the positioning clamp 20 is in internal tangential contact with the stop surface of the stop clamp 50. In this way, the stop surface of the stop clamp 50 is equivalent to a brake, which can stop the positioning clamp 20 after the positioning clamp 20 is rotated to the correct position of the lug, and the second driving part 34 can further drive the first support plate 31 to move towards one side of the first base, and make the partial outer circumferential surface of the disc structure 33 abut against the outer circumferential surface of the positioning clamp 20, so that the stop surface of the stop clamp 50 plays a braking role on the positioning clamp 20.

[0040] Optionally, the central angle of the circle where the stop surface is located ranges from 90° to 180°. In this way, by reasonably optimizing the value range of the central angle of the circle where the stop surface is located, the stop surface can have sufficient braking contact area with the outer circumferential surface of the positioning clamp 20.

[0041] As shown in Figure 1 and Figure 2 , the stop clamp 50 comprises a stop body 51 and an elastic support 52, the elastic support 52 is connected with the stop body 51, and the elastic support 52 has a stop surface. In this way, the arrangement of the elastic support 52 is beneficial to increase the friction between the stop surface and the outer circumferential surface of the positioning clamp 20, thereby ensuring the stop braking reliability of the stop clamp 50.

[0042] As shown in Figure 1 and Figure 3 , the detection mechanism 40 comprises a third driving part 41, a second support plate 42 and detection probes 43, wherein the third driving part 41 has a third driving shaft arranged in the vertical direction; the third driving shaft is drivingly connected with the second support plate 42 to drive the second support plate 42 to be arranged in a lifting manner; the detection probes 43 are two and are arranged on the second support plate 42 in a spaced manner, and the extension directions of the two detection probes 43 are arranged to be the extension direction of the lug after adjustment to the position, so that the two detection probes 43 are determined to be adjusted to the position when they are detected at the same time. In this way, the two detection probes 43 are arranged in a lifting manner, and after the positioning work of the lug is completed, the two detection probes 43 can be moved upward by the third driving part 41, so as to provide a space for avoiding the subsequent welding work of the lug and the upper cover plate.
