Description

Technical Field

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

[0002] The limit clamp for lithium battery production is a kind of fixture tooling used in the production process of lithium batteries. Its function is to limit and clamp lithium battery parts to ensure the accuracy and stability in the production process. The limit clamp is usually custom-designed to adapt to specific models and sizes of lithium batteries to ensure accurate positioning and firm clamping. They can be used in multiple production links such as cell assembly, cell welding, and cell testing, helping workers complete the work efficiently and ensuring product quality.

[0003] However, the limit clamp for lithium battery production mainly limits and clamps the lithium battery during the assembly of the lithium battery. The limit clamp only simply limits and clamps the lithium battery. However, when the lithium battery is being assembled, if the lithium battery has a short circuit, a fire will occur, and once a fire occurs in the lithium battery, the fire will spread rapidly. If the fire source is not extinguished in time, the fire will spread rapidly and cause an explosion. When a fire occurs, the operator still needs to find a fire extinguisher to extinguish the fire, and the time for finding the fire extinguisher will cause the fire to spread.

Internal thread locking sleeves 12 are threadedly sleeved outside the limiting adjustment screw A8, the limiting adjustment screw B9, the limiting adjustment screw C10, and the limiting adjustment screw D11. The four internal thread locking sleeves 12 are respectively located outside the front end of the limiting fixture plate A3, outside the right end of the limiting fixture plate B4, outside the rear end of the limiting fixture plate C6, and outside the left end of the limiting fixture plate D7.

[0023] As Figure 1 and Figure 2As shown, when using this lithium battery production limit fixture, first, the limit fixture plates A3, B4, C6, and D7 need to be placed on the fixture table 1. Then, the limit adjustment screws on the limit fixture plates A3, B4, C6, and D7 are respectively passed through the corresponding limit adjustment chutes 2, and internal thread locking sleeves 12 are threadedly sleeved on the outermost ends of the four limit adjustment screws. Then, it is necessary to adjust the limit size of the limit fixture according to the cost of lithium battery production and assembly. Specifically, it is necessary to push the limit fixture plate D7 to the right so that the limit adjustment screw at the front end of the limit fixture plate D7 slides in the limit adjustment chute 2 inside the limit fixture plate A3, push the limit fixture plate C6 forward so that the limit adjustment screw at the left end of the limit fixture plate C6 slides forward in the limit adjustment chute 2 inside the limit fixture plate D7, push the limit fixture plate B4 to the left so that the limit adjustment screw at the rear end of the limit fixture plate B4 slides to the left in the limit chute inside the limit fixture plate C6, and push the limit fixture plate A3 backward so that the limit adjustment screw at the right end of the limit fixture plate A3 slides backward in the limit adjustment chute 2 inside the limit fixture plate B4 until the area between the limit fixture plates A3, B4, C6, and D7 reaches the shape and size of the final lithium battery assembly. Then, maintain this state and tighten the four internal thread locking sleeves 12, so that the limit fixture plates A3, B4, C6, and D7 are fixed in the currently adjusted positions. Then, the lithium battery can be assembled in the area between the limit fixture plates A3, B4, C6, and D7.

[0024] As Figure 1 and Figure 3As shown in the figure, a fire-fighting device 5 is provided at the top of the rear end of the fixture table 1. The fire-fighting device 5 includes a fire-fighting adjustment slide rail 13, a T-shaped anti-slip chute 14, a dry powder storage box 17, a powder outlet fire-fighting port 18, and a T-shaped anti-slip seat 20. The fire-fighting adjustment slide rail 13 is fixed to the top of the rear end of the fixture table 1. A T-shaped anti-slip chute 14 is provided inside the fire-fighting adjustment slide rail 13. A T-shaped anti-slip seat 20 is provided in the T-shaped anti-slip chute 14. The top end of the T-shaped anti-slip seat 20 is exposed above the top end of the fire-fighting adjustment slide rail 13. A dry powder storage box 17 is provided at the front end of the top of the T-shaped anti-slip seat 20. A plurality of powder outlet fire-fighting ports 18 are equidistantly provided at the bottom of the dry powder storage box 17, and the powder outlet fire-fighting ports 18 are communicated with the inside of the dry powder storage box 17. The fire-fighting device 5 further includes a feeding port 19 and a sealing cover. The feeding port 19 is provided at the center of the top end of the dry powder storage box 17. Fire-extinguishing dry powder can be filled into the dry powder storage box 17 through the feeding port 19. An external thread of the top end of the feeding port 19 is sleeved with a sealing cover, and the sealing cover can seal the feeding port 19. The fire-fighting device 5 further includes a pull-out sealing plate 15 and a sealing plate slot 16. The sealing plate slot 16 is provided inside the front end of the dry powder storage box 17. The pull-out sealing plate 15 is inserted into the sealing plate slot 16. The pull-out sealing plate 15 can completely seal the outside of the top ends of the plurality of powder outlet fire-fighting ports 18. The dry powder storage box 17 is fixedly connected to the T-shaped anti-slip seat 20 by welding. The bottom end of the T-shaped anti-slip seat 20 can slide left and right in the T-shaped anti-slip chute 14.

[0025] As Figure 1 and Figure 3 shown in the figure, the fire-fighting adjustment slide rail 13 is fixedly connected to the fixture table 1 through a plurality of embedded screws. The dry powder storage box 17 is located above the fixture table 1, and the dry powder storage box 17 is parallel to the fixture table 1. When the fire-fighting device 5 is not in use, the T-shaped anti-slip seat 20 is located inside the left end of the T-shaped anti-slip chute 14 inside the fire-fighting adjustment slide rail 13, so that the dry powder storage box 17 is located above the left end of the fixture plate, and thus it will not hinder the operator from assembling the lithium battery. When a fire occurs in the lithium battery during the assembly process, the fire-fighting device 5 can be directly used at this time to quickly extinguish the fire source and prevent the fire source from spreading. During specific operation, it is necessary to grasp the front end of the dry powder storage box 17 and then slide it to the right. In this way, the T-shaped anti-slip seat 20 at the rear end of the dry powder storage box 17 will slide to the right through the T-shaped anti-slip chute 14 until the dry powder storage box 17 is located directly above the fire source. Then, it is necessary to grasp the pull-out sealing plate 15 and pull it forward, so that the pull-out sealing plate 15 is completely pulled out from the sealing plate slot 16. In this way, the openings at the top ends of the plurality of powder outlet fire-fighting ports 18 will be opened. At this time, the fire-extinguishing dry powder stored in the dry powder storage box 17 will fall upward through the plurality of powder outlet fire-fighting ports 18, and the downward-falling fire-extinguishing dry powder will directly spread on the fire source, so that the fire source of the lithium battery fire can be quickly extinguished, preventing the fire from further spreading, and at the same time protecting the operator.
