Description

Technical Field

[0001] This utility model relates to the field of soft-pack lithium-ion battery manufacturing equipment, specifically to a dual-station aluminum-plastic film stamping mold. Background Technology

[0002] Pouch batteries, with their thinness, high energy density, and good flexibility, have become the preferred choice for new energy vehicles and portable electronic devices. However, the stamping (forming) process of the aluminum-plastic film in their manufacturing has a significant impact on the performance of the final product, mainly in the following aspects: 1. Molding precision is directly related to sealing quality. The aluminum-plastic film of the soft-pack battery needs to be stamped with grooves that conform to the size of the electrode assembly. The flatness and dimensional deviation of the groove wall and bottom directly affect the sealing surface quality of subsequent electrolyte injection and heat sealing processes. If there are wrinkles, scratches or inconsistent dimensions on the end face of the groove, it will lead to electrolyte leakage, film blistering or local edge lifting, and in severe cases, even safety accidents.

[0003] 2. The contradiction between shell-making speed and production capacity As the production cycle of power battery production lines continues to shorten, traditional single-station stamping dies require mold separation, loading and unloading, and unloading after completing one molding process, which takes a long time. Furthermore, loading and unloading often rely on manual labor or independent robotic arms, making it difficult to meet the production demand of tens of millions of pieces per day.

[0004] 3. High requirements for mold alignment and wear resistance The complex structure of aluminum-plastic composite film materials places stringent requirements on the die closing clearance, guiding accuracy, and wear resistance of the cutting edge. Under continuous high-frequency use, single-station dies are prone to guide post wear, die misalignment, and cutting edge dulling, leading to increased stamping burrs and dimensional drift.

[0005] 4. High difficulty in automation integration Currently, most equipment on the market uses a single-station, buffered punching die connected to processes such as liquid injection and heat sealing via a conveyor chain. However, the buffer zone for each station switching process occupies a large area, resulting in high overall equipment investment and occupying factory space.

[0006] Based on the shortcomings of the existing technology, there is an urgent need for a dual-station stamping die that can achieve continuous stamping switching on a single die frame and can be seamlessly integrated with loading, unloading, and conveying systems to meet the production requirements of high capacity, high precision, and high reliability. Utility Model Content

[0007] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a dual-station aluminum-plastic film stamping mold. By setting two adjacent stamping workstations on the same mold frame, the loading and unloading and stamping actions are completed alternately, realizing parallel "processing-material changing" operations, thereby significantly improving mold utilization and production line cycle time.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a dual-station aluminum-plastic film stamping mold, including a lower template, which is set on a lower template connecting plate. The lower template connecting plate is connected to a first guide post and guide sleeve structure around its perimeter. The upper and lower ends of the first guide post and guide sleeve structure are respectively connected to a middle fixed plate and a lower fixed plate. The bottom of the lower template connecting plate is connected to a lower motor. The upper part of the middle fixed plate is connected to an upper fixed plate through a second guide post and guide sleeve structure passing through a movable plate. A pressure plate is set below the middle fixed plate, and a punch is set above the pressure plate. A punch connecting plate is connected to the punch, and the punch connecting plate is connected to an upper motor.

[0009] Preferably, the upper motor is mounted on the motor mounting plate, and the motor mounting plate is mounted on the upper fixing plate.

[0010] The beneficial effects of this utility model are: 1. Dual-station collaborative efficiency: Through the independent driving of the lower template and the punch (the lower motor controls the lifting of the lower template and the upper motor controls the lifting of the punch), the coordinated action of positioning and clamping and stamping is realized, thereby improving the efficiency of stamping.

[0011] 2. High guiding accuracy: The first guide post and guide sleeve structure (connecting the lower template connecting plate, the middle fixed plate, and the lower fixed plate) and the second guide post and guide sleeve structure (connecting the middle fixed plate, the movable plate, and the upper fixed plate) are adopted to ensure the coaxiality and stability of the lower template and the punch during the movement process, thereby improving the stamping accuracy.

[0012] 3. Compact and stable structure: Through the rigid connection of multiple layers of plates (lower template connecting plate, middle fixed plate, movable plate, upper fixed plate, etc.) with guide pillars and guide sleeves, a stable frame structure is formed, which reduces vibration during the stamping process and ensures the forming quality.

[0013] 4. Easy to operate: Automated drive (motor drive) reduces manual intervention. After the aluminum-plastic film passes through the mold cavity, it can continuously complete the positioning, stamping and release process, which is suitable for continuous production needs.

[0015] 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.

[0016] Reference Figure 1The specific embodiment adopts the following technical solution: a dual-station aluminum-plastic film stamping mold, including a lower template 1, the lower template 1 is set on the lower template connecting plate 2, the lower template connecting plate 2 is connected to the first guide post and guide sleeve structure 3 around its perimeter, the upper and lower ends of the first guide post and guide sleeve structure 3 are respectively connected to the middle fixing plate 4 and the lower fixing plate 5, the bottom of the lower template connecting plate 2 is connected to the lower motor 6, the upper part of the middle fixing plate 4 is connected to the upper fixing plate 9 through the second guide post and guide sleeve structure 7 passing through the movable plate 8, a pressure plate 10 is set below the middle fixing plate 4, a punch 11 is set above the pressure plate 10, a punch connecting plate 12 is connected to the punch 11, and the punch connecting plate 12 is connected to the upper motor 13.

[0017] It is worth noting that the upper motor 13 is mounted on the motor mounting plate 14, and the motor mounting plate 14 is mounted on the upper fixing plate 9.

[0018] The working principle of this specific implementation is as follows: After the aluminum-plastic film is conveyed to the mold cavity, the lower motor drives the lower template connecting plate and the lower template as a whole to move upward, so that the lower template fits against the pressure plate, realizing the positioning and clamping of the aluminum-plastic film; at the same time, the upper motor drives the punch downward through the punch connecting plate, and the punch and the lower template cooperate to complete the stamping and forming of the aluminum-plastic film. After stamping is completed, the punch is reset under the drive of the upper motor, and the lower template is moved downward under the drive of the lower motor, releasing the formed aluminum-plastic film and completing one stamping cycle.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
