Description

Technical Field

[0001] This utility model relates to a lithium battery sticker device, belonging to the technical field of lithium battery production equipment. Background Technology

[0002] A lithium battery is an electrochemical energy storage device that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It features high energy density, long cycle life, and low self-discharge rate. Its working principle is to achieve charge transfer through the insertion and extraction of lithium ions between the positive and negative electrodes. Common positive electrode materials include lithium cobalt oxide, lithium iron phosphate, and ternary materials, while the negative electrode is mostly graphite-based materials.

[0003] In traditional lithium battery sticker manufacturing processes, problems such as uneven sticker application leading to wrinkles and air bubbles, causing stickers to fall off and resulting in poor appearance are common. Furthermore, manual sticker application is inefficient, with each station taking 15-20 seconds to apply the sticker, making it difficult to meet the needs of large-scale production.

[0004] Therefore, it is urgent to improve the lithium battery sticker equipment to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a lithium battery sticker applicator. The applicator uses a positioning clamp to precisely hold the lithium battery, a feeding roller and traction mechanism to stably transport the sticker, a cutting mechanism to precisely cut the sticker to size or preset length, and a smoothing mechanism that uses a cylinder to press down the smoothing frame. A drive motor, via bevel gear transmission, drives a threaded rod, causing a threaded sleeve to rotate and smooth the sticker using a smoothing roller. This achieves automatic feeding, positioning, unwinding, traction, cutting, and smoothing of the lithium battery sticker. The coordinated operation of these mechanisms ensures accurate lithium battery positioning, stable sticker feeding tension, and accurate cutting length during the sticker application process. Furthermore, the smoothing process effectively eliminates wrinkles, resulting in a flat and firmly adhered sticker, improving sticker quality and consistency. Simultaneously, the automated process reduces manual intervention, increases production efficiency, and lowers production costs.

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] like Figures 1-4 As shown, the lithium battery sticker equipment provided in this embodiment includes a frame 1, a conveyor 2 is installed on the frame 1, a plurality of evenly distributed positioning fixtures 3 are installed on the conveyor belt of the conveyor 2, and a feeding roller 4 is installed at one end of the frame 1. A traction mechanism 5 is provided on one side of the feeding roller 4, a cutting mechanism 6 is provided on the other side of the traction mechanism 5, and a smoothing mechanism 7 is provided on the side of the cutting mechanism 6 away from the traction mechanism 5. The feeding roller 4, the traction mechanism 5, the cutting mechanism 6 and the smoothing mechanism 7 are all arranged above the plurality of positioning fixtures 3.

[0026] The smoothing mechanism 7 includes two smoothing cylinders 71. A smoothing frame 72 is fixedly connected to the output end of each of the two smoothing cylinders 71. A drive motor 73 is mounted on one side of the smoothing frame 72. A drive shaft 74 is fixedly connected to the output end of the drive motor 73. The end of the drive shaft 74 away from the drive motor 73 passes through the smoothing frame 72 and is rotatably connected to the inner wall of the smoothing frame 72. Two symmetrically distributed driving bevel gears 75 are fixedly mounted on the drive shaft 74. A driven bevel gear is meshed with the same side of each of the two driving bevel gears 75. 76, and a threaded rod 77 is fixedly connected to the end of the driven bevel gear 76 away from the driving bevel gear 75. The end of the threaded rod 77 away from the driven bevel gear 76 is rotatably connected to the inner wall of the smoothing frame 72. A threaded sleeve 78 is threadedly connected to the threaded rod 77. A smoothing roller 79 is arranged between the two threaded sleeves 78. The two ends of the smoothing roller 79 are respectively connected to the two threaded sleeves 78 through rotating shafts. The lithium battery is placed on the positioning clamp 3 of the conveyor belt of the conveyor 2 and is firmly clamped and conveyed. The feeding roller 4 at one end of the frame 1 is used for The sticker roll is placed, and then the traction mechanism 5 smoothly pulls the sticker out from the feed roll roller 4. At the same time, the conveying speed and tension of the sticker are controlled. When the sticker is pulled to the cutting mechanism 6, the lithium battery is conveyed to the bottom of the cutting mechanism 6. The cutting mechanism 6 cuts the sticker according to the size of the lithium battery or the preset length. The cut sticker falls vertically onto the lithium battery. After the sticker is attached to the battery, it moves forward with the lithium battery to the bottom of the smoothing mechanism 7. At this time, the two smoothing cylinders 71 immediately extend, pushing the smoothing frame 72 to move downward, so that the smoothing roller 7... 9. The sticker is brought close to the lithium battery. Then, the drive motor 73 is started, which drives the drive shaft 74 to rotate. This causes the two active bevel gears 75 on the drive shaft 74 to rotate. Through meshing, they drive the driven bevel gear 76 to rotate. The driven bevel gear 76 drives the threaded rod 77 to rotate. The threaded sleeves 78 on the two threaded rods 77 drive the smoothing roller 79 to roll on the sticker surface under the action of thread transmission. This smooths out the wrinkles on the sticker surface, ensuring that the sticker is flat and firmly attached to the lithium battery, thereby improving the sticker quality and production efficiency.

[0027] Furthermore, such as Figures 1-4 As shown, the positioning fixture 3 includes a positioning plate 31, which is installed on the conveyor belt of the conveyor 2. A positioning slide rail 32 is installed on the positioning plate 31. Two symmetrically distributed electric positioning sliders 33 are slidably connected on the positioning slide rail 32. Clamping plates 34 are installed on the electric positioning sliders 33. When the lithium battery is placed on the clamping plate 34, the two electric positioning sliders 33 slide towards each other along the positioning slide rail 32, causing the clamping plate 34 to clamp the two sides of the lithium battery simultaneously, thereby ensuring that the battery does not shift during the sticker application and smoothing process, thus improving the bonding accuracy and consistency.

[0028] Furthermore, such as Figures 1-4As shown, a feeding shaft 41 is rotatably connected to the feeding roller 4. Both ends of the feeding shaft 41 are mounted on the frame 1 via positioning nuts 42. A guide roller 8 is provided between the traction mechanism 5 and the feeding roller 4. Both ends of the guide roller 8 are mounted on the frame 1 via shafts. The traction mechanism 5 includes a traction motor 51, which is fixedly mounted on the frame 1. The output end of the traction motor 51 is fixedly connected to a drive traction roller 52 via a shaft. The end of the drive traction roller 52 away from the traction motor 51 is fixedly connected to a drive gear 53 via a shaft. A driven traction roller 54 is provided above the drive traction roller 52. Both ends of the driven traction roller 54 are mounted on the frame 1 via shafts. The end of the driven traction roller 54 near the drive gear 53 is fixedly connected to a driven gear 55 via a shaft. The driven gear 55 meshes with the drive gear 53. The cutting mechanism 6 includes a support plate 61, which is mounted on the frame 1. A linear guide rail 62 is mounted on the support plate 61. An electric slider 63 is slidably connected to the linear guide rail 62. A lifting cylinder 64 is mounted on the electric slider 63. A laser cutting blade 65 is mounted on the output end of the lifting cylinder 64. The feeding roll 4 is fixed to the frame 1 by the feeding shaft 41 and the positioning nut 42. The sticker roll is wrapped in the feeding roll 4. After the sticker direction is changed by the guide roller 8, it enters the traction mechanism 5. The traction motor 51 drives the active traction roller 52 to rotate. Through the meshing of the active gear 53 and the driven gear 55, the driven traction roller 54 is driven to rotate synchronously in the opposite direction. The two rollers clamp the sticker and pull it at a uniform speed. When the sticker is transported to the set length, the electric slider 63 moves along the linear guide rail 62 to the designated position. The lifting cylinder 64 drives the laser cutting blade 65 to descend and accurately cut the sticker. This enables the stable unwinding, guiding, traction and precise cutting of the sticker, providing sticker material of consistent length for subsequent sticker bonding to lithium batteries.

[0029] Furthermore, such as Figures 1-4 As shown, two symmetrically distributed L-shaped fixing plates 9 are installed on the frame 1. The smoothing cylinder 71 is installed on the L-shaped fixing plate 9. The two symmetrical L-shaped fixing plates 9 are fixed on the frame 1 to install the smoothing cylinder 71, provide stable support for the smoothing mechanism 7, and ensure that the smoothing roller 79 can accurately press down and adhere the sticker.

[0030] Furthermore, such as Figures 1-4 As shown, several evenly distributed mounting plates 10 are installed at the lower end of the frame 1. Two symmetrically distributed mounting holes 11 are opened on the mounting plates 10. The mounting plates 10 at the lower end of the frame 1 have symmetrical mounting holes 11, which are used to fix the whole equipment on the ground, thereby ensuring the stability of the whole equipment during operation.

[0031] like Figures 1-4 As shown, the principle of the lithium battery sticker device provided in this embodiment is as follows:

[0032] The lithium battery is placed on the clamping plate 34 of the conveyor belt of conveyor 2. Two electric positioning sliders 33 slide towards each other along the positioning guide rail 32, driving the clamping plate 34 to clamp the two sides of the lithium battery synchronously. Then, it is conveyed by conveyor 2. The sticker roll on the unloading roller 4 enters the traction mechanism 5 after the guide roller 8 changes the sticker's direction. The traction motor 51 drives the active traction roller 52 to rotate. Through the meshing of the active gear 53 and the driven gear 55, the driven traction roller 54 rotates synchronously in the opposite direction. The two rollers clamp the sticker and pull it at a uniform speed. When the sticker is conveyed to the set length, the electric slider 63 moves to the designated position along the linear guide rail 62. The lifting cylinder 64 drives the laser cutting blade 65 to descend, cutting the sticker according to the size of the lithium battery or the preset length. The sticker falls vertically onto the lithium battery. After the sticker adheres to the battery, it moves forward with the lithium battery to the smoothing mechanism 7. At this point, two smoothing cylinders 71 extend and push the smoothing frame 72 downward, bringing the smoothing roller 79 closer to the sticker and the lithium battery. Then, the drive motor 73 is started, driving the drive shaft 74 to rotate. This causes the two active bevel gears 75 on the drive shaft 74 to rotate, which in turn drives the driven bevel gear 76 to rotate. The driven bevel gear 76 drives the threaded rod 77 to rotate. The threaded sleeves 78 on the two threaded rods 77, under the action of threaded transmission, drive the smoothing roller 79 to roll against the sticker surface, smoothing out the wrinkles on the sticker surface and ensuring that the sticker is flat and firmly adhered to the lithium battery, thereby improving the sticker quality and production efficiency.
