Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery production and processing, and particularly relates to a fixing device for lithium battery production. Background Technique

[0002] A lithium battery is a type of battery with a lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Mobile phones and laptop computers use lithium-ion batteries, which are commonly known as lithium batteries. Batteries generally use materials containing lithium elements as electrodes and are representatives of modern high-performance batteries. With the progress of the times, the usage rate of lithium batteries has greatly increased. When processing lithium batteries, it is necessary to fix the lithium batteries to achieve the processing effect.

[0003] For example, in a fixing device for lithium battery production and processing with the patent application number 202222042335.2, it includes a base. A placement plate is fixedly installed on the top of the base through bolts. A left baffle is fixedly installed at the left end of the top of the placement plate through bolts. A left fixing plate is arranged on the right side of the left baffle. The left baffle is connected to the left fixing plate through an electric telescopic rod A. A right baffle is fixedly installed at the right end of the top of the placement plate through bolts. A right fixing plate is arranged on the left side of the right baffle. The right baffle is connected to the right fixing plate through an electric telescopic rod B. By operating the electric telescopic rod A and the electric telescopic rod B provided in this device, the left fixing plate and the right fixing plate move towards each other, thereby fixing the lithium battery. This fixing device is reasonably designed, has a simple structure, and firm clamping, making the lithium battery not easy to fall off during the processing process, and eliminating the need for manual adjustment of clamping, thereby improving work efficiency.

[0004] Although the above mechanism can realize the clamping and fixing of the lithium battery through two relatively moving fixing plates, the two simple fixing plates have a single structure. And the existing lithium batteries have various shapes with many concave and convex surfaces. When clamping other-shaped lithium batteries with only two fixing plates, the contact area is often small while the clamping pressure will be concentrated on the convex surface, resulting in poor stability of the lithium battery after clamping and being prone to damage. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a fixing device for lithium battery production. The utility model realizes the clamping and fixing of the lithium battery through the relative movement of two clamping components, and self-adapts to different-shaped lithium batteries during the clamping process, making the stability of the lithium battery good after clamping. And the clamping head on the clamping rod can be detachably replaced with different-shaped clamping heads, further improving the stability of the lithium battery after clamping. The clamping head is made of rubber material to avoid damage to the lithium battery during the clamping process.

[0006] To achieve the above object, the present utility model provides the following technical solution: A fixing device for lithium battery production, including a support base, on which two clamping components are symmetrically arranged. The clamping component includes a sliding plate slidably arranged on the upper end surface of the support base. One side of the sliding plate is provided with a limiting plate, and a plurality of outer ring seats are arranged on the end surface of the limiting plate. A limiting ring is arranged in each outer ring seat, and an elastic ring is connected between the limiting ring and the outer ring seat. A clamping rod is slidably arranged in the limiting ring, and a plurality of the clamping rods can generate sliding offset and angular swing according to the shape of the lithium battery.

[0007] Preferably, four two-by-two grouped support plates are symmetrically arranged on the outer end surface of the sliding plate. In both groups of support plates, a U-shaped rotating frame is rotatably arranged, and the two rotating frames are distributed crosswise. Rotating rods are rotatably arranged at both ends of the rotating frame, and a square plate is abutted against the outside of the rotating rod. The square plate is connected to one end of the clamping rod.

[0008] Preferably, a spring is connected between the limiting plate and the square plate on the outside of each clamping rod.

[0009] Preferably, support frames are fixedly arranged on both sides of the upper end surface of the support base. A bidirectional screw rod is rotatably connected between the two support frames, and the bidirectional screw rod drives the two sliding plates to move respectively.

[0010] Preferably, a base is arranged on the sliding plate, and a motor for driving the screw rod to rotate is arranged on the base.

[0011] Preferably, two square guide rods are symmetrically arranged on one side end surface of the support frame, and the square guide rods are used to limit the movement of the sliding plate.

[0012] Preferably, a detachable clamping head is arranged on the end surface of the end of a plurality of the clamping rods extending out of the limiting plate.

[0013] In summary, compared with the prior art, the beneficial effects of this solution are as follows:

[0014] (1) The present utility model realizes the clamping and fixing of the lithium battery by the relative movement of two clamping components. During the clamping process, a plurality of clamping rods can generate sliding offset and angular swing according to the shape of the lithium battery, realizing the function of self-adapting to different shaped lithium batteries during the clamping process, thereby increasing the contact area with the lithium battery and making the stability of the lithium battery good after clamping;

Specific embodiments

[0022] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] Refer to Figures 1-5 As shown, a fixing device for lithium - battery production includes a support base 1. Two clamping assemblies are symmetrically arranged on the support base 1. The clamping assembly includes a sliding plate 2 slidably arranged on the upper end surface of the support base 1. A limit plate 3 is arranged on one side of the sliding plate 2. A plurality of outer ring bases 4 are arranged on the end surface of the limit plate 3. A limit ring 5 is arranged in each outer ring base 4. An elastic ring 6 is connected between the limit ring 5 and the outer ring base 4. A clamping rod 7 is slidably arranged in the limit ring 5. The plurality of clamping rods 7 can slide and shift and swing at an angle according to the shape of the lithium battery.

[0024] When clamping and fixing a lithium battery, two sets of clamping components move relative to each other to achieve the clamping and fixing of the lithium battery. During the clamping and fixing process, the clamping rod 7 can slide within the limiting ring 5, and through the cooperative setting of the elastic ring 6, both the limiting ring 5 and the outer ring seat 4 are made of hard materials, enabling the clamping rod 7 to slide smoothly. Among them, the elastic ring 6 is made of flexible material. When multiple clamping rods 7 clamp and fix the lithium battery, when there are grooves on the outer surface of the lithium battery, multiple clamping rods 7 can generate a certain sliding offset and angular swing according to the shape of the lithium battery. During this process, the end of the clamping rod 7 will swing due to the uneven contact surface, and the elastic ring 6 will be deformed under pressure, enabling the clamping rod 7 to self-fit the shape of the lithium battery, with high adaptability and a large clamping area, thereby improving the overall clamping stability of the lithium battery.

[0025] Specifically, referring to Figure 2 、 Figure 4 、 Figure 5 As shown, four pairwise groups of support plates 8 are symmetrically arranged at the outer end face of the sliding plate 2. Two U-shaped rotating frames 9 are rotatably arranged within both groups of support plates 8. The two rotating frames 9 are distributed in an intersecting manner. Rotating rods 10 are rotatably arranged at both ends of the rotating frame 9. A square plate 11 is abutted and arranged outside the rotating rod 10. One end of the square plate 11 is connected to the clamping rod 7.

[0026] When the sliding plate 2 moves, it drives the two U-shaped rotating frames 9 to rotate, and at the same time drives the two rotating rods 10 to rotate, and then pushes multiple square plates 11 and multiple clamping rods 7 to have sliding offset and angular swing, enabling the device to better self-fit the shape of the lithium battery during the clamping process and improving the practicality of the device.

[0027] Specifically, referring to Figure 4 、 Figure 5 As shown, a spring 12 is connected and arranged outside each clamping rod 7 between the limiting plate 3 and the square plate 11.

[0028] When clamping and fixing the lithium battery, the spring 12 enables multiple clamping rods 7 to slide different distances on the limiting plate 3 through its own elastic force, so as to be able to clamp and fix lithium batteries with different shapes, with high adaptability and good clamping and fixing effects; and when the clamping and fixing work is not carried out, the spring 12 can assist the clamping rod 7 to reset, facilitating the next clamping and fixing work.

[0029] Specifically, referring to Figure 1 、 Figure 5 As shown, support frames 13 are fixedly arranged on both sides of the upper end face of the support base 1. A bidirectional screw rod 14 is rotatably connected between the two support frames 13, and the bidirectional screw rod 14 drives the two sliding plates 2 to move respectively.

[0030] Both ends of the bidirectional screw 14 are provided with bidirectional threads. When the bidirectional screw 14 rotates, it drives the two-sided sliding plates 2 to move relatively, clamping and fixing the lithium battery.

[0031] Specifically, referring to Figure 5 As shown, a base 15 is provided on the sliding plate 2, and a motor 16 for driving the bidirectional screw 14 to rotate is provided on the base 15.

[0032] Start the motor 16. The output end of the motor 16 drives the bidirectional screw 14 to rotate, and then drives the two clamping assemblies to move relatively, realizing the clamping and fixing of the lithium battery; the motor 16 is a prior art, and this solution will not be elaborated too much.

[0033] Specifically, referring to Figure 5 As shown, two square guide rods 17 are symmetrically arranged on one end face of the support frame 13. The square guide rods 17 are used to limit the movement of the sliding plate 2.

[0034] The two square guide rods 17 have a limiting effect on the sliding plate 2, assisting the sliding plate 2 to slide stably on the support base 1.

[0035] Specifically, referring to Figure 4 As shown, detachable clamping heads 18 are provided on the end faces of the multiple clamping rods 7 extending from one end of the limiting plate 3.

[0036] The clamping heads 18 on the clamping rods 7 can be detached, facilitating the replacement of different-shaped clamping heads 18, further improving the stability of the lithium battery after clamping. And the clamping heads 18 are made of rubber material, which has a protective effect on the lithium battery, avoiding damage to the lithium battery during the clamping process. The specific detachable structure in the above solution is a prior art, and this solution will not be elaborated too much.

[0037] Working principle: When in use, start the motor 16. When the motor 16 works, it will drive the bidirectional screw 14 to rotate, thereby driving the two clamping components to move relatively, realizing the clamping and fixing of the lithium battery. When the lithium battery with uneven outer surface is clamped by the present utility model, the head ends of the plurality of clamping rods 7 abut against the uneven surface of the lithium battery, and then continuous pressure is applied. At this time, under the action of the pressure, while the plurality of clamping rods 7 slide in the limiting ring 5, due to the uneven outer surface of the lithium battery, the plurality of clamping rods 7 will automatically swing at a certain angle through the arrangement of the elastic ring 6. At the same time, the plurality of springs 12 will also expand and contract. At this time, the clamping rod 7 will then drive the plurality of rotating rods 10 to rotate at a certain angle in the rotating frame 9, prompting the clamping rod 7 to complete the angle swing. When the angle of the clamping rod 7 swings to a certain extent, the plurality of rotating frames 9 will also rotate in the support plate 8 to increase the amplitude of the angle swing. The plurality of clamping rods 7 can slide and offset and swing at an angle according to the shape of the lithium battery by themselves, so as to adapt to lithium batteries of different shapes, with high adaptability. At the same time, when clamping, the contact area with the outer surface of the lithium battery is large, and the stability of the lithium battery after clamping is good. And the clamping head 18 on the clamping rod 7 can be disassembled, which is convenient to replace with clamping heads of different shapes, further improving the stability of the lithium battery after clamping. And the clamping head 18 is made of rubber material, which has a protective effect on the lithium battery and avoids damage to the lithium battery during the clamping process.
