Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing devices, in particular to a lithium ion battery processing fixing fixture. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. They are deeply loved by major companies because of their advantages such as high energy density, light weight and long life. Lithium batteries include three forms: cylindrical, soft-pack and square. In the production and processing of square lithium-ion batteries, the paired battery cells need to be placed in an aluminum shell, and the shell and cover need to be welded.

[0003] The existing clamps clamp the lithium battery in the left-right direction or the up-down direction by setting two clamping plates. Since the lithium battery is clamped in only one direction, the clamping force needs to be increased to effectively clamp the lithium battery during welding. If the clamping force is too large, the surface of the lithium battery will be damaged. If the clamping force is too small, the lithium battery will easily be displaced during the processing. In addition, general clamps cannot adjust the processing angle of the lithium battery, which makes the processing process extremely inconvenient. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] Embodiment: A lithium-ion battery processing fixture, such as Figure 1-Figure 4 As shown, it includes a base plate 1 and a bracket 2, the bracket 2 is symmetrically welded and fixed on the top of the base plate 1, and also includes a rotating component, a clamping component, a lateral pushing component and a battery body 001. A rotating component is arranged between the two brackets 2, and the clamping components are symmetrically arranged on the rotating component. The battery body 001 is arranged between the two clamping components. The clamping component is used to fix and clamp the battery body 001, and the rotating component is used to drive the clamping component to rotate so as to adjust the processing angle of the battery body 001. The rotating component is provided with a lateral pushing component for lateral pushing the two clamping components to move closer to or away from each other.

[0022] like Figure 1 As shown, the rotating assembly includes a rotating shaft 21, a locking screw 22 and an I-shaped mounting plate 23. The upper parts of the two brackets 2 are rotatably connected to the rotating shaft 21, the top of the bracket 2 on the right side is threadedly connected to the locking screw 22, and an I-shaped mounting plate 23 is welded and fixed between the two rotating shafts 21.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the clamping assembly includes a sliding plate 31, a fixed plate 32, a fixed splint 33, a sliding splint 34 and an electric push rod 35. The sliding plates 31 are symmetrically slidably connected to the I-shaped mounting plate 23. The fixed plates 32 are welded and fixed on the sides of the two sliding plates 31 that are close to each other. The fixed splints 33 are welded and fixed on the lower parts of the two fixed plates 32. The sliding splints 34 are slidably connected to the upper parts of the two fixed plates 32. The electric push rods 35 are installed on the sides of the two fixed plates 32 that are away from each other. The two electric push rods are fixedly connected to the bottoms of the adjacent sliding splints 34.

[0024] like Figure 2 As shown, the lateral pushing assembly includes a bidirectional screw rod 41, a motor 42, a large gear 43 and a small gear 44. The lower part of the I-shaped mounting plate 23 is rotatably connected to the bidirectional screw rod 41, and the motor 42 is installed at the bottom of the I-shaped mounting plate 23. The large gear 43 is fixedly connected to the output shaft of the motor 42. The middle part of the bidirectional screw rod 41 is fixedly connected to the small gear 44. The large gear 43 and the small gear 44 are meshed with each other. The bidirectional screw rod 41 passes through the lower part of the two sliding plates 31 respectively, and cooperates with the two sliding plates 31 through threads respectively.

[0025] First, take a battery body 001 to be processed, start the electric push rod 35, and the telescopic rod of the electric push rod 35 extends, thereby pushing the sliding clamp 34 away from the adjacent fixed clamp 33, and then start the motor 42, the motor 42 drives the bidirectional screw rod 41 to rotate, thereby pushing the two sliding plates 31 to approach each other. When the distance between the two fixed plates 32 is close to the width of the battery body 001, the battery body 001 is placed on the top of the two fixed clamps 33, and the two fixed plates 32 continue to move in the direction of approaching each other, thereby moving the battery body 001 in the left and right directions. The battery body 001 is clamped and then the electric push rod 35 is started. The telescopic rod of the electric push rod 35 retracts to drive the two sliding clamps 34 to move downward, so that the sliding clamps 34 and the fixed clamps 33 clamp and fix the battery body 001 in the upper and lower directions. In this way, the battery body 001 can be effectively fixed so that the battery body 001 will not be displaced during the welding process. After loosening the locking screw 22, the I-shaped mounting plate 23 can be rotated to adjust the angle of the clamping assembly and the battery body 001 mounted thereon, thereby making the welding process more convenient.

[0026] like Figure 2 and Figure 4 As shown, a placement plate 5 is also included, and the placement plate 5 is welded and fixed to the middle part of the I-shaped mounting plate 23.

[0027] By setting up the placement plate 5, since the upper surface of the placement plate 5 and the upper surface of the fixing clamp 33 are at the same horizontal height, when installing the battery body 001, it only needs to be placed on the placement plate 5, and there is no need to first adjust the two fixing clamps 33 to a distance between them that is close to the width of the battery body 001. This makes the use of the device more convenient and quick.

[0028] like Figure 3 As shown, a buffer pad 6 is also included. The buffer pad 6 is provided on the side where the adjacent fixed clamping plates 33 and the sliding clamping plates 34 are close to each other.

[0029] The provision of the buffer pad 6 can effectively prevent the sliding clamping plate 34 and the fixed clamping plate 33 from damaging the surface of the battery body 001 .

[0030] like Figure 1 and Figure 2 As shown, a rubber plate 7 is also included. The rubber plate 7 is arranged at the bottom of the base plate 1.

[0031] The provision of the rubber plate 7 enables the device to be placed on the table more stably.

[0032] like Figure 2 As shown, it also includes a limit seat 8. Two limit seats 8 are fixedly connected to the I-shaped mounting plate 23 near the middle of the bidirectional screw rod 41, and the bidirectional screw rod 41 passes through the two limit seats 8 respectively.

[0033] By setting the limit seats 8, the two limit seats 8 support and fix the middle part of the bidirectional screw rod 41 to avoid the bidirectional screw rod 41 being too long and causing the middle part to bend, which ultimately makes the large gear 43 and the small gear 44 unable to mesh.

[0034] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
