Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, specifically to a high-speed casing punching machine pressure roller mechanism. Background Technology

[0002] In encapsulation processes such as top-side sealing of lithium batteries, traditional pressure roller mechanisms have the following key problems:

[0003] 1. Conflict between speed and precision: When feeding at high speed (≥60m / min), the edge of the film is prone to deviation (≥±0.5mm) due to vibration of the pressure roller or uneven pressure, which cannot meet the requirements of the encapsulation process for the edge precision (±0.1mm); the traditional cylinder pressing response is delayed (≥0.3 seconds), and high-speed start and stop can easily cause the film material to slip or be stretched and deformed.

[0004] 2. Insufficient structural rigidity: The clearance between the guide post and guide sleeve is large (≥0.05mm), and the pressure roller swings significantly during high-speed operation, affecting the straightness of material conveying; the motor and pressure roller are driven by belt / chain, which is subject to elastic deformation and wear, and the cumulative error leads to a deviation in the material conveying length (±0.3%).

[0005] 3. Poor maintenance and adaptability: Replacing the membrane material requires manual disassembly of the pressure roller assembly, with downtime exceeding 5 minutes; traditional pressure rollers are not compatible with membrane materials of different thicknesses (such as 8-20μm), requiring frequent adjustment of air pressure parameters.

[0006] In summary, this utility model designs a pressure roller mechanism for a high-speed shell punching machine. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-speed punching machine pressure roller mechanism with reasonable structural design, which can simultaneously meet the requirements of high-speed material feeding and high-precision material feeding, and has strong practicality.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-speed shell-punching machine pressure roller mechanism, comprising a pressure roller component mounted on the high-speed shell-punching machine. The pressure roller component includes a motor, a reducer, a coupling, a reducer mounting base, a feed roller, an adjusting plate, an adjusting screw mounting block, a base plate, a vertical plate, a top plate, a cylinder, guide pillars and guide sleeves, a connector, a pressure block, a movable plate, a shaft mounting block, an upper pressure roller, a rubber roller mounting shaft, and a limiting ring. The motor is connected to the reducer, and the reducer's rotating shaft is connected to the feed roller's shaft via a coupling. The feed roller is positioned in the middle of the vertical plate. The reducer reduces speed... The machine mounting base is installed on the outside of the upright plate. A base plate is fixed between the bottom ends of the upright plate. A slide rail is provided at the bottom of the base plate. The slide rail cooperates with the slider fixed on the high-speed punching machine. The adjusting plate is fixed on the base plate. The top plate is connected to the adjusting plate through the upright plate. A cylinder is provided on the top plate. Guide posts and guide sleeves are provided on both sides of the cylinder. The cylinder rod passes through the movable plate and is connected to the upper pressure roller through the connector. A pressure block is provided between the connectors. The guide posts on the outside of the pressure block are connected to both ends of the movable plate. Shaft mounting blocks are provided on both sides of the bottom of the movable plate. The upper pressure roller is installed between the shaft mounting blocks through the rubber roller mounting shaft. Limit rings are provided on both sides of the upper pressure roller.

[0009] Preferably, the bottom plate is also provided with a locking block on its side that can be locked to the high-speed punching machine.

[0010] The beneficial effects of this utility model are as follows: By integrating a servo drive system, a high-precision linear guide, and a rapid pressure adjustment mechanism, this utility model solves the three major technical problems of insufficient precision, poor rigidity, and low adaptability of traditional pressure roller mechanisms under high-speed operation. It achieves a film edge positioning accuracy of ±0.08mm when feeding material at a high speed of 60m / min, and the changeover adjustment time is shortened to within 1 minute.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Reference Figure 1-2The specific embodiment adopts the following technical solution: a high-speed shell punching machine pressure roller mechanism, including a pressure roller component B installed on the high-speed shell punching machine A. The pressure roller component B includes a motor 1, a reducer 2, a coupling 3, a reducer mounting base 4, a feed roller 5, an adjusting plate 6, an adjusting screw mounting block 8, a base plate 9, a vertical plate 10, a top plate 11, a cylinder 12, a guide column and guide sleeve 13, a connector 14, a pressure block 15, a movable plate 16, a shaft mounting block 17, an upper pressure roller 18, a rubber roller mounting shaft 19, and a limiting ring 20. The motor 1 is connected to the reducer 2. The rotating shaft of the reducer 2 is connected to the roller shaft of the feed roller 5 through a coupling. The feed roller 5 is located in the middle of the vertical plate 10. The reducer 2 is installed on the vertical plate 10 through the reducer mounting base 4. On the outside, a base plate 9 is fixed between the bottom ends of the upright plate 10. A slide rail 21 is provided at the bottom of the base plate 9. The slide rail 21 cooperates with the slider fixed on the high-speed punching machine A. An adjusting plate 6 is fixed on the base plate 9. The top plate 11 is connected to the adjusting plate 6 through the upright plate. A cylinder 12 is provided on the top plate 11. Guide posts and guide sleeves 13 are provided on both sides of the cylinder 12. The cylinder rod of the cylinder 12 passes through the connecting head 14 and is connected to the upper pressure roller 18 through the movable plate 16. A pressure block 15 is provided between the connecting heads 14. The guide posts on the outside of the pressure block 15 are connected to both ends of the movable plate 16. Shaft mounting blocks 17 are provided on both sides of the bottom of the movable plate 16. The upper pressure roller 18 is installed between the shaft mounting blocks 17 through the rubber roller mounting shaft 19. Limit rings 20 are provided on both sides of the upper pressure roller 18.

[0016] It is worth noting that the bottom plate 9 is also provided with a locking block 7 that is locked to the high-speed punching machine A.

[0017] The working principle of this specific embodiment is as follows: The upper pressure roller is driven by a cylinder and guided by a high-precision guide post and guide sleeve. The feed roller is fixed between two vertical plates. The motor and reducer are connected and fixed on the mounting base. The mounting base is fixed on the vertical plate. The reducer is directly connected to the feed roller through a coupling. In the working state, the cylinder extends and drives the upper pressure roller to press the feed roller tightly. The motor runs continuously and drives the feed roller to rotate and transport the film forward. When the film needs to be replaced, the motor stops and the cylinder retracts.

[0018] This specific implementation employs a cylinder-driven pressing system with high-precision guide pillars and sleeves, achieving a repeatability of ±0.05mm and resolving vibration and misalignment issues during high-speed operation. The direct-drive transmission structure, where the motor is connected to the feed roller via a reducer, eliminates the elastic deformation of traditional belt drives, keeping the length deviation within ±0.1% during high-speed feeding at 60m / min. A unique quick-release slide rail design, combined with a locking block mechanism, reduces membrane replacement time from the traditional 5 minutes to 30 seconds, significantly improving overall equipment efficiency. This integrated design is the first to simultaneously achieve a fusion of high precision, high speed, and high adaptability within a single pressure roller mechanism.
