Description

Technical Field

[0001] This utility model relates to the field of lithium battery accessory processing, specifically a fixing device for the production and processing of lithium battery accessories. Background Technology

[0002] Lithium-ion batteries use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. The production of lithium-ion batteries requires many components, which need to be fixed during manufacturing. However, existing fixing devices often allow these components to move freely during processing, resulting in low stability and reduced processing efficiency. One proposed fixing device for lithium-ion battery component manufacturing, patent number "CN202222356695.X", uses a drive motor to bring a friction pad at the bottom of a fixing plate into contact with the top of the lithium-ion battery component. The cooperation between the fixing plate, support plate, and friction pad ensures a more secure and reliable manufacturing process, effectively preventing movement. However, this device still has room for improvement: because the drive motor clamps the component, the fixing plate lacks a buffer structure upon contact, resulting in excessive clamping force that can damage the component and negatively impact battery lifespan.

[0017] In practical use: Guide posts 51 are installed at both ends of the surface of the fixed clamping plate 45. The guide posts 51 slide through the limiting sleeves 52 installed at both ends of the mounting strip 44. A buffer spring 53 is sleeved on the surface of the guide post 51. When the fixed clamping plate 45 contacts the lithium battery accessory, the fixed clamping plate 45 applies a clamping force to the accessory. The fixed clamping plate 45 drives the guide post 51 to slide inside the limiting sleeve 52, so that the fixed clamping plate 45 compresses the buffer spring 53. Through the deformation and compression of the buffer spring 53, the fixed clamping plate 45 gradually clamps the accessory, avoiding the fixed clamping plate 45 directly applying a large clamping force to the accessory under the push of the cylinder 42, effectively avoiding damage to the accessory, thereby ensuring the service life of the lithium battery.

[0018] Please see Figure 3 The mounting cavity 2 is equipped with a support 6. A support plate 7 is fixedly installed in the middle of the support 6. A transmission rod 8 is rotatably installed in the middle of the support plate 7. A swing arm 9 is hinged to both ends of the transmission rod 8. A slide rail 10 is fixedly installed at both ends of the support 6. A slider 11 is fixedly installed at the bottom of the movable seat 3. The slider 11 is slidably installed on the surface of the slide rail 10. One end of the swing arm 9 is hinged to the surface of the movable seat 3.

[0019] In practical use: A support plate 7 is installed in the middle of the support 6. A transmission rod 8 is rotatably installed in the middle of the support plate 7. A swing arm 9 is hinged to both ends of the transmission rod 8. One end of the swing arm 9 is hinged to the surface of the movable seat 3. When the transmission rod 8 rotates, it drives the movable seat 3 through the swing arm 9, so that the movable seat 3 slides on the slide rail 10 at both ends of the support 6 through the bottom slider 11. This allows the two movable seats 3 to move closer or further apart, satisfying the placement and fixing of accessories of different sizes. The damping blocks 18 installed at both ends of the slide rail 10 limit the sliding range of the movable seat 3.

[0020] Please see Figure 4 A rotating shaft 12 is rotatably mounted on the bottom end of the support plate 7. The top of the rotating shaft 12 is fixedly connected to the transmission rod 8. A gear ring 13 is fixedly mounted on the bottom of the rotating shaft 12. A servo motor 14 is fixedly mounted on one side of the bottom end of the support plate 7. A gear 15 is fixedly mounted on the output end of the servo motor 14. The gear 15 meshes with the gear ring 13.

The rubber dust cover 17 is set on both sides of the sliding direction of the movable seat 3, so that when the movable seat 3 slides back and forth, the rubber dust cover 17 can seal the travel groove 16 and at the same time prevent parts from falling into the base 1 and affecting the use of the device.

[0024] Guide posts 51 are installed at both ends of the surface of the fixed clamping plate 45. The guide posts 51 slide through the limiting sleeves 52 installed at both ends of the mounting strip 44. A buffer spring 53 is sleeved on the surface of the guide post 51. When the fixed clamping plate 45 contacts the lithium battery accessory, the fixed clamping plate 45 applies a clamping force to the accessory. The fixed clamping plate 45 drives the guide post 51 to slide inside the limiting sleeve 52, so that the fixed clamping plate 45 compresses the buffer spring 53. Through the deformation and compression of the buffer spring 53, the fixed clamping plate 45 gradually clamps the accessory, avoiding the fixed clamping plate 45 directly applying a large clamping force to the accessory under the push of the cylinder 42, effectively avoiding damage to the accessory, thereby ensuring the service life of the lithium battery.
