[0002] With the rapid development of electronic products (such as smartphones, tablets, and laptops), electric vehicles, and energy storage devices, the demand for lithium-ion batteries has exploded. As a key piece of equipment in lithium-ion battery production, the performance and reliability of lithium-ion battery winding machines directly impact the quality and production efficiency of these batteries. For example, the expanding electric vehicle market demands higher energy density, longer cycle life, and improved safety for lithium-ion batteries, placing even higher demands on the winding machine's precision and stability.

[0003] The winding process for lithium-ion batteries involves the process of winding the positive and negative electrodes and separators in a specific manner to form a cell. During this process, the stability and consistency of the clamping mechanism are crucial. Clamping issues, such as excessive clamping force leading to electrode deformation and separator damage, or insufficient clamping force resulting in loose material and uneven winding, can seriously impact the performance and quality of the battery cell.

[0004] However, the existing clamping alarm device can only detect the clamping force of the lithium battery cell at a single position and in a single direction during use, resulting in incomplete clamping detection of the lithium battery cell, which affects subsequent lithium battery cell detection work.

During use, the clamping force of the lithium battery can be detected more comprehensively.

[0020] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0021] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1 to 3 As shown, an embodiment of the present invention provides a clamping alarm device for a lithium battery cell winding machine, comprising a clamping mechanism 1 disposed on the winding machine, characterized in that the clamping mechanism 1 is provided with a mounting seat 11, a strain gauge sensor 2 is disposed within the mounting seat 11, and the strain gauge sensor 2 is provided with an alarm electrically connected thereto (not shown in the figure), a horizontal moving member 3 is disposed within the mounting seat 11, the horizontal moving member 3 is rotatably connected to the mounting seat 11, an angular rotation member 4 is disposed on the horizontal moving member 3, and the strain gauge sensor 2 is mounted on the angular rotation member 4. The strain gauge sensor 2 is of model HBM PW15AHC3 / 150KG;

[0023] During use, the clamping force generated by the clamping mechanism 1 is detected by the strain gauge sensor 2, and an alarm is given through the alarm when the clamping force becomes larger or smaller. The horizontal moving component 3 can drive the position of the strain gauge sensor 2 to move horizontally, and the clamping force is detected at different positions. The angle position of the strain gauge sensor 2 is driven to rotate and change by the angle rotating component 4, and the clamping force of different types of lithium batteries can be clamped.

[0024] Specifically, the horizontal moving member 3 includes a moving block 31, a horizontal screw rod 32, a drive motor 33 and a horizontal rod 34. The horizontal screw rod 32 is rotatably connected to the mounting seat 11. The drive motor 33 is located on the outer wall of the mounting seat 11 and is transmission-connected to the horizontal screw rod 32. The horizontal rod 34 is arranged in the mounting seat 11. The moving block 31 is threadedly connected to the horizontal screw rod 32, and the moving block 31 is slidingly matched with the horizontal block.

[0025] There are multiple key positions in the clamping mechanism 1 of the winding machine where clamping force detection is required, or due to product specifications, process changes, etc., the clamping force at different positions needs to be dynamically monitored. At this time, the position of the strain gauge sensor 2 needs to be moved; in large winding machines, the clamping mechanism 1 is large in size, and the clamping force in different areas may be different. By moving the strain gauge sensor 2, the distribution of the clamping force can be more comprehensively understood.

[0026] The driving motor 33 drives the horizontal screw rod 32 to rotate on the mounting base 11, thereby driving the moving block 31 to move horizontally on the horizontal rod 34. The movement of the position of the moving block 31 can drive the position of the strain gauge sensor 2 to move. In the process of clamping the lithium battery cell, the clamping force at different positions on the lithium battery cell is detected.

[0027] Specifically, the angle rotation component 4 includes a rotating motor 41, a rotating frame 42 and two mounting ears 43. The two mounting ears 43 are symmetrically arranged at the bottom of the moving block 31. The rotating frame 42 is rotatably connected to the two mounting ears 43. The rotating motor 41 is connected to the mounting ears 43 and the rotating motor 41 is transmission-connected to the rotating frame 42.

[0028] When measuring the clamping force of a winding machine, different positions and angles may correspond to different clamping conditions and force scenarios. Some winding machines have complex clamping structures, or the product experiences varying postures and angles during the clamping process. Strain gauge sensors with angle adjustment can better meet these requirements.

[0029] For example, during the winding process of some special-shaped battery cells, the distribution of the clamping force may vary with the shape of the battery cell and the winding angle. By adjusting the angle of the strain gauge sensor 2, the clamping force at the key position can be measured more accurately.

[0030] The rotating motor 41 can drive the rotating frame 42 to rotate on the two mounting ears 43. The rotation of the rotating frame 42 can drive the angular position of the strain gauge sensor 2 to rotate and change, thereby detecting different types of lithium batteries.

[0031] Specifically, the mounting seat 11 and the clamping mechanism 1 are detachably connected. The clamping mechanism 1 is provided with four connecting ears 12 , and the clamping mechanism 1 is connected to the mounting seat 11 via the four connecting ears 12 .

[0032] After use, the strain gauge sensor 2 can be removed from the clamping mechanism 1 for inspection and maintenance. The connecting ear 12 is provided with screws for connection, and disassembly and installation are convenient and fast.

[0033] Specifically, the strain gauge sensor 2 is installed at the bottom of the rotating frame 42; during use, the strain gauge sensor 2 moves downward to clamp and contacts the lithium battery cell to detect the clamping force, and an alarm is issued through the alarm when the clamping force becomes larger or smaller.

[0034] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
