Description

Technical Field

[0001] This utility model relates to the field of soft-pack lithium battery production technology, specifically a clamping device for soft-pack lithium battery production. Background Technology

[0002] The production of pouch lithium batteries requires clamping devices. The outer shell of pouch lithium batteries is usually made of aluminum-plastic film with a thickness of only 0.1-0.2mm. The internal electrode materials are delicate and fragile, and are easily damaged during handling and assembly. Clamping devices can accurately clamp, handle, and assemble pouch lithium batteries during production, avoiding battery damage and ensuring product quality and production efficiency. For example, WOMMER's electric gripper uses flexible force control technology, which can improve the clamping force control accuracy to ±0.05N, avoiding cell damage caused by excessive pressure. It can also automatically adjust the gripping posture and movement trajectory according to the shape and weight of the cell. Combined with a vision recognition system, it can achieve micron-level placement accuracy. In addition, Huangshan Huaruiyuan Technology Co., Ltd. has obtained a patent for "a clamping device for pouch lithium battery production". Through the combination of electric telescopic rod and clamping plate, it can accurately control the clamping force and range. The movable arc-shaped worm gear ring can support and limit the pouch lithium battery, improving clamping stability.

[0003] Patent publication number "CN222138028U" discloses "A clamping device for producing soft-pack lithium batteries, comprising: a fixed plate, with a connector fixedly connected to the top surface of the fixed plate; a clamping structure mounted on the bottom surface of the fixed plate, the clamping structure including a movable plate, the movable plate being movably mounted on the right end of the bottom surface of the fixed plate via a rotating shaft, a threaded rod being movably mounted on the inner side of the movable plate via a bearing, a motor being mounted on the left side wall of the movable plate, a short clamping plate and a long clamping plate being slidably mounted on the inner side of the bottom surface of the movable plate, and an electric telescopic rod being mounted on the left end of the top surface of the fixed plate."

[0031] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1 to 4This application provides a clamping device for producing soft-pack lithium batteries, including a cylinder 1. A lifting frame 2 is fixedly connected to the output end of the cylinder 1. A clamping assembly 3 is connected to the inner side wall of the lifting frame 2 via bearings. A power assembly 5 is fixedly installed on the inner top wall of the lifting frame 2. The power assembly 5 includes a motor 51 and a second gear 52. The motor 51 is fixedly installed on the inner top wall of the lifting frame 2. The second gear 52 is fixedly connected to the output end of the motor 51, and the second gear 52 meshes with a first gear 32. A limit assembly 4 is fixedly installed on the top of the clamping assembly 3. The clamping assembly 3 includes a bidirectional threaded rod 31 and a first gear 32. The bidirectional threaded rod 31 is connected to the inner bottom wall of the lifting frame 2 via bearings, and the first gear 32 is fixedly connected to the bidirectional threaded rod 31. On the side wall of the cylinder 1, a movable plate 33 is threadedly connected to the side wall of the bidirectional threaded rod 31. A slide rod 34 is fixedly installed on the inner side wall of the lifting frame 2. The movable plate 33 and the slide rod 34 are slidably connected. An adjusting plate 35 is fixedly installed at the bottom of the movable plate 33. A sliding plate 36 is slidably connected to the bottom of the adjusting plate 35. A base plate 37 is fixedly installed at the bottom of the sliding plate 36. A fixing frame 38 is fixedly installed on one side of the sliding plate 36. A threaded rod 39 is threadedly connected to one side of the fixing frame 38. The threaded rod 39 is engaged with the adjusting plate 35. The clamping assembly 3 also includes a knob 310. The knob 310 is fixedly connected to one end of the threaded rod 39. A mounting bracket is fixedly installed on the side wall of the cylinder 1. A bolt is threadedly connected to the top of the mounting bracket.

[0033] In this embodiment, pulling the slide plate 36 allows it to slide on the side wall of the adjusting plate 35. Turning the knob 310 allows the threaded rod 39 to move on one side of the fixed frame 38, so that the threaded rod 39 can engage with the adjusting plate 35 to adjust the clamping capacity of the clamping assembly 3. Then, turning on the cylinder 1 allows the lifting frame 2 to move downwards. Turning on the motor 51 allows the gear 52 to rotate. The gear 52 then drives the gear 32 to rotate, so that the gear 32 can drive the moving plate 33 to slide on the side wall of the slide bar 34 via the bidirectional threaded rod 31. The moving plate 33 then grips the lithium battery via the base plate 37, which is simple and convenient, ensuring the effectiveness of use.

[0034] Reference Figures 1 to 4 In one aspect of this embodiment, the limiting component 4 includes a rectangular plate 41 and a threaded rod 42. The rectangular plate 41 is fixedly installed on the top of the base plate 37. The threaded rod 42 is threadedly connected to one side of the rectangular plate 41. One end of the threaded rod 42 is connected to the limiting plate 43 via a bearing. The limiting component 4 also includes a stabilizing rod 44, which is fixedly installed on one side of the limiting plate 43. The stabilizing rod 44 is slidably connected to the rectangular plate 41. The limiting component 4 also includes a knob 45, which is fixedly connected to one end of the threaded rod 42.

[0035] In this embodiment, firstly, rotating the knob 45 can drive the threaded rod 42 to move on one side of the limiting plate 43, so that the limiting plate 43 can drive the stabilizing rod 44 to slide on one side of the rectangular plate 41. Then, the limiting plate 43 can perform limiting work when clamping the lithium battery, making it easier to clamp.

[0036] Working principle: First, rotating knob 45 can drive threaded rod 42 to move on one side of limiting plate 43, so that limiting plate 43 can drive stabilizing rod 44 to slide on one side of rectangular plate 41. Then, limiting plate 43 can perform limiting work when clamping lithium battery, making it easier to clamp.

[0037] Then, pulling the slide plate 36 allows it to slide on the side wall of the adjustment plate 35. Turning the knob 310 allows the threaded rod 39 to move on one side of the fixed frame 38, so that the threaded rod 39 can engage with the adjustment plate 35 to adjust the clamping capacity of the clamping assembly 3. Then, turning on the cylinder 1 allows the lifting frame 2 to move downward. Turning on the motor 51 allows the gear 52 to rotate. Then, the gear 52 will drive the gear 32 to rotate, so that the gear 32 can drive the moving plate 33 to slide on the side wall of the slide bar 34 through the bidirectional threaded rod 31. Then, the moving plate 33 will grip the lithium battery through the base plate 37. The gripping is simple and convenient, ensuring the effectiveness of use.
