DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the application.

[0039] Embodiment one: please refer to Figures 1-10The existing battery cell overturning device can clamp and overturn the battery cell by the relative movement of two plate-shaped components. Although the plate-shaped components can clamp the battery cell, they cannot effectively limit the rectangular or cylindrical battery cell. When the plate-shaped components clamp the cylindrical battery cell, the small contact area between the arc surface of the cylindrical battery cell and the plane of the plate-shaped component can easily cause the battery cell to fall during overturning. To solve this technical problem, the present embodiment discloses the following technical content. A battery cell polarity overturning device includes an overturning module 11 mounted on a support base 1. The overturning module 11 is used to overturn a vertically placed battery cell and place the overturned battery cell on a second conveying line 12 for transmission. The overturning module 11 includes a lifting guide rail 111, and a rotary air cylinder 112 is mounted on the lifting guide rail 111. The output end of the rotary air cylinder 112 is provided with a clamping seat 113, and the middle part of the clamping seat 113 is fixed with a power air cylinder 114. The telescopic end of the power air cylinder 114 is provided with a pressing block 115, and the side of the pressing block 115 is provided with a movable block 116. The movable block 116 is connected with each other through an auxiliary spring 117 and a containing block 118. The side of the movable block 116 is fixed with a control clamping arm 119. The control clamping arm 119 is provided with a positioning unit 13 and a movable unit 14. The spacing between the movable unit 14 and the positioning unit 13 is adjusted to adapt to the limiting of battery cells with different cross-sectional shapes. The mutual contact surfaces of the pressing block 115 and the movable block 116 are both provided with inclined surfaces, and the movable block 116 is symmetrically arranged about the transverse central axis of the pressing block 115. The movable block 116 forms an elastic telescopic structure through the auxiliary spring 117 and the containing block 118. A supporting plate 1110 is arranged between the control clamping arms 119 on both sides of the containing block 118. The supporting plate 1110 is used to support the bottom of the battery cell. The positioning unit 13 and the movable unit 14 on the control clamping arm 119 are both provided with a cylindrical structure. A moving plate 15 is fixed on the movable unit 14. The moving plate 15 is connected with the control clamping arm 119 through a first spring 16. A first electromagnet 18 is fixed on the side of the moving plate 15. A first magnetic block 17 is embedded on the side of the moving plate 15 which is in contact with the first electromagnet 18. A limiting control plate 19 is arranged between the movable unit 14 and the positioning unit 13. The end of the limiting control plate 19 away from the movable unit 14 is connected with the control clamping arm 119 through a second spring 20. A second magnetic block 21 is embedded on the end of the limiting control plate 19 which extends into the control clamping arm 119. A second electromagnet 22 is fixed on the side of the second magnetic block 21. The moving plate 15 on the movable unit 14 can slide on the control clamping arm 119, and the positioning unit 13 is fixed on the control clamping arm 119. The first electromagnet 18 can generate a magnetic attraction force on the first magnetic block 17 on the moving plate 15 after being electrified. The second electromagnet 22 can generate a magnetic attraction force on the second magnetic block 21 on the limiting control plate 19 after being electrified.The limiting control plate 19 and the control clamp arm 119 are in sliding connection, and the end side of the limiting control plate 19 located outside the control clamp arm 119 is provided in an arc shape. The end side of the limiting control plate 19 located outside the control clamp arm 119 is close to one side of the movable unit 14, and when moving towards the control clamp arm 119, the movable unit 14 can be extruded. The end side of the limiting control plate 19 located outside the control clamp arm 119 is close to one side of the positioning unit 13, and when moving towards the control clamp arm 119, the limiting control plate 19 does not contact the positioning unit 13. The positioning unit 13 and the movable unit 14 are located on the same horizontal line, and the surface of the end of the limiting control plate 19 extending outside the control clamp arm 119 is flush with the positioning unit 13 and the movable unit 14 in the initial state.

[0040] When it is necessary to turn over the rectangular battery cell, the opening of the power cylinder 114 can make the extrusion block 115 move. After the extrusion block 115 moves, the movable block 116 can be extruded by the inclined edge. At this time, the movable block 116 and the control clamp arm 119 move towards the outside of the containing block 118. After the movable block 116 moves, the auxiliary spring 117 is compressed. Then, the battery cell is placed on the supporting plate 1110 on the containing block 118. The power cylinder 114 controls the extrusion block 115 to retreat. At this time, the movable block 116 and the control clamp arm 119 are reset and rebound under the action of the auxiliary spring 117. After resetting, the control clamp arm 119 clamps and fixes the side of the rectangular battery cell through the movable unit 14, the positioning unit 13 and the limiting control plate 19 thereon. Because the limiting control plate 19 is flush with the movable unit 14 and the positioning unit 13 in the initial state, the contact area with the side of the rectangular battery cell can be increased by using the limiting control plate 19. After the battery cell is limited, the rotating cylinder 112 controls the clamping seat 113 to rotate, so as to turn over the limited battery cell and place it on the second conveying line 12 on the side for conveying. When it is necessary to turn over the cylindrical battery cell, first open the second electromagnet 22. After the second electromagnet 22 is opened, the second magnetic block 21 at the end of the limiting control plate 19 can generate a magnetic attraction force. At this time, the limiting control plate 19 moves towards the outside of the control clamp arm 119. After the limiting control plate 19 moves, the movable unit 14 can be extruded by the arc surface, so that the movable unit 14 moves away from the positioning unit 13, and the distance between the positioning unit 13 and the movable unit 14 is increased. After adjusting the movable unit 14, the first electromagnet 18 is opened. After the first electromagnet 18 is electrified, the first magnetic block 17 on the moving plate 15 is adsorbed, so as to fix the position of the moving movable unit 14. By increasing the distance between the movable unit 14 and the positioning unit 13, the stability of the cylindrical battery during limiting can be improved. The specific limiting state is shown in Figure 9 and Figure 10 .

The clamping and conveying component 4 includes a moving seat 401, the moving seat 401 can move on the horizontal movement module 3, a limiting cylinder 402 is installed on the moving seat 401, and the extension end of the positioning clamping jaw 403 is fixed with the positioning clamping jaw 403.

[0042] When the battery cell is processed, the battery cell is transmitted through the battery cell transmission line 2, the moving seat 401 can be moved through the horizontal movement module 3, the opening of the limiting cylinder 402 can clamp the battery cell through the positioning clamping jaw 403, then the movement of the moving seat 401 is controlled by the horizontal movement module 3, so that the clamped battery cell is placed in the code scanning module 5, the height detection module 6 and the thickness detection module 7 in turn for parameter detection, after the parameter detection of the battery cell, the mechanical gripper 9 is moved through the gantry bracket 8, and the mechanical gripper 9 is used to clamp and convey the battery cell after detection, and the unqualified battery cell is clamped and conveyed to the first conveying line 10 for transmission.
