[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 3 As shown, the present invention includes a housing 1, a limiting groove 2, a fixing groove 3, a control device 4, and a bearing 5. The limiting groove 2 is opened on the left side of the housing 1, the fixing groove 3 is opened on the right side of the inner wall of the limiting groove 2, the control device 4 is installed on the right side of the inner wall of the fixing groove 3, the bearing 5 is installed on the top and bottom of the left side of the inner wall of the fixing groove 3, and a clamping mechanism 6 is installed on the inner wall of the bearing 5.

[0024] refer to Figure 2 The clamping mechanism 6 includes a bidirectional screw 61, which is fixedly connected to the inner ring of the bearing 5. The surface of the bidirectional screw 61 is threaded with a clamping arm 62, and a motor 63 is installed at the bottom of the right side of the inner wall of the fixing groove 3.

[0025] As a technical optimization of this utility model, by setting up a clamping mechanism 6, the bidirectional screw 61 can drive the clamping arm 62 to move and clamp the lithium battery, and the motor 63 can drive the transmission wheel 7 to rotate.

[0026] refer to Figure 3 The output end of motor 63 is fixedly connected to a transmission wheel 7, and the bottom of the surface of bidirectional screw 61 is fixedly connected to a transmission wheel 8.

[0027] As a technical optimization of this utility model, by setting up a first transmission wheel 7 and a second transmission wheel 8, the first transmission wheel 7 can drive the transmission belt 9 to rotate when it rotates, the transmission belt 9 can drive the second transmission wheel 8 to rotate, and the second transmission wheel 8 can drive the bidirectional screw 61 to rotate.

[0028] refer to Figure 3 The output end of motor 63 is fixedly connected to a transmission wheel 7, and the bottom of the surface of bidirectional screw 61 is fixedly connected to a transmission wheel 8.

[0029] As a technical optimization of this utility model, by setting a transmission belt 9 and a gear 10, after the lithium battery is fixed by the clamping arm 62, the rubber block 12 abuts against the gear 10 to increase the friction with the gear 10, so that the bidirectional screw 61 stops rotating and is fixed, thus preventing loosening during clamping.

[0030] refer to Figure 2 An electric push rod 11 is fixedly connected to the right side of the top of the inner wall of the fixed groove 3, and a rubber block 12 is fixedly connected to the piston end of the electric push rod 11.

[0031] As a technical optimization of this utility model, by setting an electric push rod 11 and a rubber block 12, after the lithium battery is clamped, the electric push rod 11 pushes the rubber block 12, which can stop the bidirectional screw 61 from rotating, thus avoiding loosening during clamping and causing the lithium battery to fall off.

[0032] refer to Figure 2 A reference plate 13 is installed on the inner wall of the fixing groove 3. The reference plate 13 is located on the left side of the control device 4. A capacitive miniature displacement sensor 14 is fixedly connected to the right side of the clamping arm 62.

[0033] As a technical optimization of this utility model, by setting a reference plate 13 and a capacitive micro displacement sensor 14, the moving speed and moving distance of the clamping arm 62 are detected by the capacitive micro displacement sensor 14 when the clamping arm 62 moves. The reference plate 13 can block the capacitive micro displacement sensor 14, making it convenient for the capacitive micro displacement sensor 14 to perform detection.

[0034] refer to Figure 2 A pressure sensor 15 is fixedly connected to one side of the clamping arms 62 that are close to each other, and a rubber pad 16 is fixedly connected to one side of the pressure sensor 15.

[0035] As a technical optimization of this utility model, by setting a pressure sensor 15 and a rubber pad 16, the pressure sensor 15 can detect the clamping pressure, and then when the pressure reaches a certain value, the motor 63 is turned off, and then the electric push rod 11 is started to lock the bidirectional screw 61.

[0036] refer to Figure 2 A mounting bracket 17 is installed on the right side of the outer casing 1. A slide rail 18 is provided on the right side of the mounting bracket 17. A moving device 19 is fixedly connected to the right side of the mounting bracket 17.

[0037] As a technical optimization of this utility model, by setting a fixed frame 17, a slide rail 18 and a moving device 19, the moving device 19 can rotate and move along the slide rail 18, and the fixed frame 17 can drive the outer shell 1 to move when it moves, which can transport the lithium battery and make the processing more convenient.

[0038] The working principle and usage process of this utility model are as follows: During use, the fixing slot 3 provides installation space for the control device 4. The bidirectional screw 61 can drive the clamping arm 62 to move, clamping the lithium battery. The motor 63 can drive the transmission wheel 7 to rotate. When the transmission wheel 7 rotates, it drives the transmission belt 9 to rotate. The transmission belt 9 drives the transmission wheel 8 to rotate, which in turn drives the bidirectional screw 61 to rotate. After the clamping arm 62 fixes the lithium battery, the rubber block 12 abuts against the gear 10, increasing the friction with the gear 10, causing the bidirectional screw 61 to stop rotating and be fixed, preventing loosening during clamping. After clamping the lithium battery, the rubber block 12 is pushed by the electric push rod 11. To stop the rotation of the bidirectional screw 61 and prevent loosening during clamping, which could cause the lithium battery to fall out, a capacitive micro displacement sensor 14 detects the moving speed and distance of the clamping arm 62 as it moves. The reference plate 13 can block the capacitive micro displacement sensor 14, facilitating its detection. The pressure sensor 15 can detect the clamping pressure. When the pressure reaches a certain value, the motor 63 is turned off, and the electric push rod 11 is activated to lock the bidirectional screw 61. The moving device 19 can rotate and move along the slide rail 18. When the fixed frame 17 moves, it can drive the outer shell 1 to move, which can transport the lithium battery and make processing more convenient.

[0039] In summary, this clamping device for lithium battery processing provides installation space for the control device 4 by setting a fixing groove 3, and the limiting groove 2 can limit and guide the clamping mechanism 6. The clamping mechanism 6 can clamp the lithium battery, which solves the problem that the existing clamping device cannot adjust the position of the clamping arm and requires manual adjustment of the clamping arm spacing, which is very inconvenient during operation.
