Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 9 shown, a battery cell bending device provided by the present invention includes a battery cell bending mechanism 100. The battery cell bending mechanism 100 includes a processing table 101. The front side of the left side of the top of the processing table 101 is fixedly connected with a frame 102. The right side of the inner bottom of the frame 102 is fixedly connected with a first cylinder 103. The piston end of the first cylinder 103 is fixedly connected with a lower pressing plate 104. The right side of the top of the frame 102 is fixedly connected with a second cylinder 105. The piston end of the second cylinder 105 penetrates into the inside of the frame 102 and is fixedly connected with an upper pressing plate 106. The top of the right side of the frame 102 is fixedly connected with a detection component 200. The top of the processing table 101 is fixedly connected with a turntable component 300.

[0023] Referring to Figure 2 , the detection component 200 includes an electric cylinder 201. The left side of the electric cylinder 201 is fixedly connected with the top of the right side of the frame 102. The output end of the electric cylinder 201 is fixedly connected with a sensor 202.

[0024] As a technical optimization scheme of the present invention, by setting the detection component 200, when the position of the battery cell moves between the upper pressing plate 106 and the lower pressing plate 104, the electric cylinder 201 is started to drive the sensor 202 to move downward to detect whether there is a deviation in the height of the corresponding battery cell at present. If it is confirmed to be correct, the first cylinder 103 and the second cylinder 105 can be started, which can avoid the deviation of the bending position of the battery cell.

[0025] Referring to Figure 8 , the turntable component 300 includes an electric turntable 301. The bottom of the electric turntable 301 is fixedly connected with the top of the processing table 101. The top of the electric turntable 301 is fixedly connected with a supporting plate 302. There are twelve supporting plates 302 and they are distributed at equal intervals in a ring shape.

[0026] As a technical optimization solution of the present utility model, by setting the turntable assembly 300, the battery cells to be bent are placed above the pallet 302. Then, starting the electric turntable 301 will drive the twelve pallets 302 to rotate for feeding. The bent battery cells can also be sent out through the pallet 302, ensuring the smoothness and processing efficiency during the processing of the battery cells.

[0027] The working principle and usage process of the present utility model: When performing the bending work on the battery cells, the battery cells to be bent are placed above the pallet 302. Then, starting the electric turntable 301 will drive the twelve pallets 302 to rotate. When the position of one of the pallets 302 moves between the upper pressing plate 106 and the lower pressing plate 104, start the electric cylinder 201 to drive the sensor 202 to move downward to detect whether there is a deviation in the height of the corresponding battery cell at present. If it is confirmed to be correct, the first cylinder 103 and the second cylinder 105 can be started, thereby driving the upper pressing plate 106 and the lower pressing plate 104 to move inward simultaneously towards the inside of the battery cell, so as to bend the battery cell. Then, start the electric turntable 301 to drive the pallet 302 to rotate, transfer the bent battery cells out, and transfer the unbent battery cells to the bending position.

[0028] To sum up: For this battery cell bending device, by setting the upper pressing plate 106 and the lower pressing plate 104, it can apply upward and downward forces to the battery cells simultaneously, ensuring the bending quality, and solving the problem that in the traditional pressing method, one side of the pressing plate is often fixed, and the pressure is applied on the other side to press and form. However, this method cannot guarantee the accuracy, and when the pressing plate on the side applying the pressure retracts, it often catches the pressed part of the battery cell, resulting in insufficient bending of the battery cell and difficulty in ensuring the quality.
