Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, specifically to a fixture for lithium battery processing. Background Technology

[0002] A battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. The lithium metal battery was first proposed and studied in 1912, and the lithium-ion battery was proposed and researched in the 1970s. Due to the highly reactive chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have now become the mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. In the process of lithium battery processing, clamps are needed to hold the battery. Chinese patent CN212096086U discloses a fixture for lithium battery processing, comprising two fixed plates symmetrically fixedly connected to the top of a worktable. One of the fixed plates has a through groove starting from the middle, and a first pushing column is slidably inserted into the inner cavity of the through groove. A first screw is rotatably connected to one side of the first pushing column, and a first fixing block is fixedly connected to the other side of the first pushing column. This utility model utilizes the arrangement of arc blocks, the first fixing block, and the second fixing block. When clamping a square lithium battery, the two arc blocks clamp the outer wall of the round lithium battery, which is beneficial for clamping two different shapes of lithium batteries. When producing two shapes of lithium batteries at the same time, there is no need to change the fixture, which saves production time. Current clamps typically use manual rotation of threads for clamping, but thread transmission is inefficient, resulting in time and labor costs, reduced efficiency in clamping and removing batteries, and hindering production. To address this, we propose a clamp for lithium battery processing. Utility Model Content

[0003] The purpose of this utility model is to provide a clamp for lithium battery processing, so as to solve the problem mentioned in the background art that when clamping, the screw is usually turned manually, which has low screw transmission efficiency, resulting in time and effort, reducing the efficiency of clamping and removing the battery, and is not conducive to production.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fixture for processing lithium batteries, including a base, a placement plate fixed on the top of the base, a clamping mechanism on the outer side of the placement plate, and a switching mechanism on the outer side of the clamping mechanism; The clamping mechanism includes symmetrically through grooves extending through the top of the placement plate, with slide rods symmetrically fixed between the two sides of the grooves, a slider sliding on the outer side of the slide rods, a clamping plate connected to the top of the slider via the switching mechanism, and a clamping block fixed to the middle of one side of the clamping plate. The clamping mechanism also includes connecting shafts fixed to the bottom of both sides of the slider, an electric telescopic rod fixed to the bottom center of the placement plate, a movable frame fixed to the output shaft end of the electric telescopic rod, and inclined slots symmetrically opened on both sides of the movable frame. The switching mechanism includes a rotating shaft fixed to the center of the top of the slider, and the clamping plate rotating outside the rotating shaft. The top of the slider has symmetrically opened contraction cavities. A connecting spring is fixed to the center of the bottom of the contraction cavity. A connecting plate is fixed to the top of the connecting spring. A clamping head is fixed to the center of the top of the connecting plate. The bottom of the clamping plate has symmetrically opened positioning grooves. A fastening bolt is connected through the top of the clamping plate. The top of the slider has symmetrically opened screw holes.

[0005] As a further description of the above technical solution: The slider is located inside the groove, and one side of the clamping block is provided with an arc surface.

[0006] As a further description of the above technical solution: The connecting shaft slides inside the inclined groove.

[0007] As a further description of the above technical solution: The connecting plate slides inside the contraction cavity, the end of the clamp head is hemispherical, the positioning groove is a hemispherical groove, and the fastening bolt is screwed into the inside of the screw hole.

[0008] Compared with the prior art, the beneficial effects of this utility model are: 1. This lithium battery processing fixture, by activating the electric telescopic rod, drives the moving frame to rise, causing the connecting shaft to move inside the inclined groove, thereby bringing the connecting shaft closer together, driving the sliders closer together, and causing the clamping plates to come closer together, thus clamping the lithium battery. This avoids manually turning the screw, saving time and effort, improving clamping and unloading efficiency, and improving overall processing efficiency.

[0009] 2. This lithium battery processing fixture, by removing the fastening bolt from the screw hole, rotates the clamping plate, causing the positioning groove to press against the clamping head, causing the clamping head to retract into the shrinking cavity and press against the connecting spring. When the clamping plate deflects 180 degrees, the connecting spring resets, causing the clamping head to be embedded in the positioning groove, thus positioning the clamping plate. Then, the fastening bolt is screwed into the screw hole, so that the clamping blocks are aligned, which facilitates clamping according to the shape of the battery, making it suitable for the production of batteries of different shapes and improving the applicability of the device.

[0015] This utility model provides a clamp for lithium battery processing, which avoids manual screw rotation, saving time and effort, improving clamping and unloading efficiency, and enhancing overall processing efficiency. Please refer to [link / reference]. Figure 1 It includes a base 1, and a placement plate 2 is fixed on the top of the base 1; Please refer to it again. Figure 1 A clamping mechanism 3 is provided on the outside of the placement plate 2, and a switching mechanism 4 is provided on the outside of the clamping mechanism 3. Please refer to it again. Figure 2 The clamping mechanism 3 includes a symmetrical groove 301 that runs through the top of the placement plate 2. A slide rod 302 is symmetrically fixed between the two sides of the groove 301, and a slider 303 slides on the outside of the slide rod 302. Please refer to it again. Figure 2 The top of the slider 303 is connected to a clamping plate 304 via a switching mechanism 4, and a clamping block 305 is fixed to the middle of one side of the clamping plate 304.

[0016] Please refer to it again. Figure 2 The clamping mechanism 3 also includes a connecting shaft 306 fixed to the bottom of both sides of the slider 303, and an electric telescopic rod 307 fixed to the bottom center of the placement plate 2. Please refer to it again. Figure 2 The output shaft end of the electric telescopic rod 307 is fixed with a movable frame 308, and inclined slots 309 are symmetrically opened on both sides of the movable frame 308.

[0017] In summary, by activating the electric telescopic rod 307, the moving frame 308 is raised, causing the connecting shaft 306 to move inside the inclined groove 309. This brings the connecting shafts 306 closer together, causing the sliders 303 to move closer together, and the clamping plates 304 to move closer together, thereby clamping the lithium battery. This avoids manually turning the screw, saving time and effort, improving clamping and removal efficiency, and enhancing overall processing efficiency.

[0018] Please refer to it again. Figure 2 The slider 303 is located inside the slide groove 301, and the clamping block 305 has an arc surface on one side.

[0019] Please refer to it again. Figure 2 The connecting shaft 306 slides inside the inclined groove 309.

[0020] Please refer to it again. Figure 3 and Figure 4 The switching mechanism 4 includes a rotating shaft 401 fixed to the top center of the slider 303, and a clamping plate 304 rotating outside the rotating shaft 401. A contraction cavity 402 is symmetrically opened on the top of the slider 303. A connecting spring 403 is fixed to the bottom center of the contraction cavity 402. A connecting plate 404 is fixed to the top of the connecting spring 403. A clamping head 405 is fixed to the top center of the connecting plate 404. A positioning groove 406 is symmetrically opened on the bottom of the clamping plate 304. A fastening bolt 407 is connected through the top of the clamping plate 304. A screw hole 408 is symmetrically opened on the top of the slider 303.

[0021] Please refer to it again. Figure 3 and Figure 4 The connecting plate 404 slides inside the contraction cavity 402, the end of the clamp 405 is hemispherical, the positioning groove 406 is a hemispherical groove, and the fastening bolt 407 is screwed into the inside of the screw hole 408.

[0022] In summary, by removing the fastening bolt 407 from the screw hole 408 and rotating the clamping plate 304, the positioning groove 406 presses against the clamping head 405, causing the clamping head 405 to retract into the shrinkage cavity 402 and press against the connecting spring 403. When the clamping plate 304 deflects 180 degrees, the connecting spring 403 resets, causing the clamping head 405 to be embedded in the positioning groove 406, thus positioning the clamping plate 304. Then, the fastening bolt 407 is screwed into the screw hole 408, so that the clamping blocks 305 are aligned, which facilitates clamping according to the shape of the battery, making it suitable for the production of batteries of different shapes and improving the applicability of the device.

[0023] In practical use, those skilled in the art connect the electrical components to an external power source and control switch. When it is necessary to clamp the lithium battery, the lithium battery is placed at the top center of the placement plate 2. By activating the electric telescopic rod 307, the moving frame 308 is raised, causing the connecting shaft 306 to move inside the inclined groove 309. This brings the connecting shafts 306 closer together, causing the sliders 303 to move closer together, and thus the clamping plates 304 to move closer together, thereby clamping the lithium battery. This process can be repeated when clamping lithium batteries of different shapes. Remove the fastening bolt 407 from the screw hole 408, rotate the clamping plate 304 so that the positioning groove 406 presses against the clamping head 405, causing the clamping head 405 to retract into the shrinking cavity 402 and press against the connecting spring 403. When the clamping plate 304 deflects 180 degrees, the clamping head 405 is embedded in the positioning groove 406 by the reset of the connecting spring 403, positioning the clamping plate 304. Then screw the fastening bolt 407 into the screw hole 408 so that the clamping blocks 305 are aligned, completing the adjustment and facilitating the clamping of lithium batteries of different shapes.
