Description

Technical Field

[0001] The present application relates to the field of lithium battery technology, and specifically to a clamp for lithium battery production. Background Art

[0002] Lithium batteries, as a power source with high energy density and long cycle life, are widely used in portable electronic devices, electric vehicles, and energy storage systems. In the lithium battery production process, the top and side sealing and gluing process is crucial to the battery packaging quality.

[0003] During the packaging process, the clamp is an important tool for fixing and positioning lithium batteries. Chinese Patent Publication No.: CN218137564U discloses a lithium battery top sealing clamp, including a bottom plate, a placement plate fixedly connected at the center of the top of the bottom plate, vertical plates fixedly connected to the left and right sides of the top of the bottom plate, first threaded rods threadedly connected on the opposite sides of the two vertical plates, and first turning handles fixedly connected on the opposite sides of the two first threaded rods. The position of the clamp can be fixed and limited to avoid displacement between the box body and the top cover during the sealing of the top cover, resulting in misalignment. By setting the above structure, it has the advantage of being easy to align the corners of the lithium battery top cover and the box body when fixing the lithium battery box cover. However, the above scheme also has the following defects: by manually rotating the threaded rod to adjust the clamping plate, the accuracy of the adjustment position cannot be ensured, and position deviation is likely to occur when clamping lithium batteries of different sizes, affecting the packaging effect.

The clamping plates 3 are used to clamp the lithium batteries to be packaged. The second moving mechanism is used to drive the clamping plates 3 to move back and forth in two degrees of freedom along the center of the clamp seat 1 to accommodate lithium batteries of different lengths.

[0026] The first moving mechanism and the second moving mechanism respectively include a first bidirectional screw 4 and a second bidirectional screw 10. The first bidirectional screw 4 and the second bidirectional screw 10 have opposite threads at both ends for driving the sliding plate 5 and the clamping plate 3 to move and clamp the lithium battery to be packaged.

[0027] During use, the lithium battery to be packaged is placed on the clamp seat 1, and the sliding plate 5 and the clamping plate 3 are respectively driven by the first moving mechanism and the second moving mechanism to move outward through the center point of the clamp seat, so that the lithium battery to be packaged can be self-positioned and clamped, avoiding deviation during the clamping process of lithium batteries of different sizes and ensuring the packaging accuracy.

[0028] In some embodiments, the first bidirectional screw 4 and the second bidirectional screw 10 are powered by the first motor 7 and the second motor 2 respectively, so as to drive the first bidirectional screw 4 and the second bidirectional screw 10 to rotate, thereby driving the sliding plate 5 and the clamping plate 3 to move; by driving the bidirectional screws to move by the motor, a synchronous clamping effect can be achieved, and at the same time, by driving by the motor, automatic clamping can be achieved, thereby avoiding the inefficiency of manual screw rotation and improving packaging efficiency.

[0029] In some embodiments, the first moving mechanism further includes two first sliders 8 , which are threadedly connected to both ends of the first bidirectional screw 4 , and the upper ends of the first sliders 8 are fixedly connected to the sliding plate 5 .

[0030] Specifically, the first bidirectional screw 4 is rotatably connected inside the first slide groove 6, and the first slider 8 is slidably connected inside the first slide groove 6; when in use, the first motor 7 is started to drive the first bidirectional screw 4 to rotate inside the first slide groove 6, and then drive the two first sliders on the first bidirectional screw 4 to slide inside the first slide groove 6, and then drive the two sliding plates 5 to move back and forth along the center of the clamp seat 1 to the left and right with two degrees of freedom, which can adapt to the clamping of lithium batteries of different widths.

[0031] In some embodiments, the second moving mechanism further includes two second sliders 12 , which are threadedly connected to both ends of the second bidirectional screw 10 , and the upper ends of the second sliders 12 are fixedly connected to the clamping plate 3 .

[0032] Specifically, the second bidirectional screw 10 is rotatably connected inside the second slide groove 11, and the second slider 12 is slidably connected inside the second slide groove 11; when in use, the second motor 2 is started to drive the second bidirectional screw 10 to rotate inside the second slide groove 11, and then drive the two second 12 sliders on the second bidirectional screw 10 to slide inside the second slide groove 11, and then drive the two clamping plates 3 to move back and forth in two degrees of freedom along the center of the clamp seat 1, which can adapt to clamping lithium batteries of different lengths.

[0033] In some embodiments, the clamping plate 3 is arranged in an "L" shape, and a pressure sensor 9 is provided on the inner side of the clamping plate 3 for sensing the pressure of clamping the lithium battery to ensure that the lithium battery is properly clamped and not damaged.

[0034] Working principle: During use, a fixture for lithium battery production first drives the sliding plate 5 and the clamping plate 3 to move outward along the center of the fixture seat 1 through the first motor 7 and the second motor 2 respectively, and then adjusts according to the lithium battery to be inspected. Then, the lithium battery to be inspected is placed between the sliding plate 5 and the clamping plate 3, and then the first motor 7 and the second motor 2 are reversed to make the sliding plate 5 and the clamping plate 3 move closer to the center to clamp the lithium battery. The pressure applied to the lithium battery during the clamping process is monitored by the pressure sensor 9 to ensure that the lithium battery is properly clamped, but will not be damaged due to excessive pressure. When the lithium battery is properly clamped, the fixture stops working, and subsequent processing operations on the lithium battery can be carried out at this time.
