Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping machine technology, and in particular to a stamping machine for punching and cutting packaging films. Background Technology
[0002] Encapsulation films are widely used in power batteries, energy storage batteries, solid-state batteries, photovoltaic cells, and electronic products. Encapsulation films prevent external impurities, moisture, and oxygen from penetrating the product, thus avoiding corrosion or damage and effectively extending the product's lifespan and improving its stability. The existing process for producing encapsulation films using a stamping machine is as follows:
[0003] The punching tool used to punch out the outline of the encapsulation film is fixed on the worktable of the stamping machine. Then, the encapsulation film material is placed on the punching tool. The worktable is driven to move the punching tool and the encapsulation film material on it to the pressure plate of the stamping machine. Then, the hydraulic cylinder is controlled to drive the pressure plate to move down and press on the encapsulation film material. The encapsulation film product is formed under the punching of the punching tool.
[0004] The existing stamping machine has only one station, resulting in poor production continuity, long intervals between two stamping operations, and low production efficiency.
[0005] During the punching process, the punching blade creates cuts on the pressure plate. When these cuts are deep, the blade may fail to cut through the encapsulation film. Therefore, after a period of punching, the position of the pressure plate needs to be adjusted to prevent the blade from acting on the same spot for an extended period. However, in existing punching machines, the pressure plate position adjustment requires manual intervention, which is cumbersome to install and remove, inconvenient to adjust, and inefficient. Utility Model Content
[0006] In view of this, the purpose of this utility model is to provide a front and rear dual-station stamping machine to solve the technical problems of low production efficiency and poor ease of pressure plate position adjustment in existing encapsulation film stamping machines.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] like Figures 1-4 As shown, the front and rear dual-station stamping machine in this embodiment includes a frame 1, a pressure-bearing platform 2 fixed on the frame, guide columns 3 arranged on the left and right sides of the frame, a top seat 4 arranged on the upper end of the guide columns, a lifting seat 5 that slides vertically with the guide columns, and a hydraulic cylinder 6 vertically arranged on the top seat for driving the lifting seat to move up and down. It also includes a front support 7 arranged on the front side of the frame, a front worktable 8 arranged on the front support, a first linear actuator 9 that drives the front worktable to move back and forth, a rear support 10 arranged on the rear side of the frame, a rear worktable 11 arranged on the rear support, and a second linear actuator 12 that drives the rear worktable to move back and forth. The bottom surfaces of the front worktable and the rear worktable slide with the top surface of the pressure-bearing platform, respectively.
[0022] In this embodiment, the first linear actuator 9 and the second linear actuator 12 are hydraulic cylinders arranged horizontally on the frame. The bottom surfaces of the front worktable 8 and the rear worktable 11 are provided with transmission seats 13. The piston rod ends of the first linear actuator 9 and the second linear actuator 12 are respectively provided with transmission pins 14 connected to the corresponding transmission seats.
[0023] This embodiment features a dual-station stamping machine with two stations, allowing two workers to use the machine simultaneously. During the production of the encapsulation film, the workers at both stations can alternately move the front and rear worktables under the pressure plate for stamping operations, thereby significantly reducing the interval between two stamping operations and improving the production efficiency of the stamping machine.
[0024] As an improvement to the above embodiment, the front and rear dual-station stamping machine further includes a pressure plate 15, a support pin 16, and a crossbar 17; the pressure plate is located on the bottom surface of the lifting seat, and the support pin is vertically fixed on the front and rear sides of the lifting seat; the crossbar is provided with a plurality of strip holes 18, the length direction of the strip holes is parallel to the pressure plate, the strip holes are sleeved on the support pin, and the support pin is slidably engaged with the strip holes; the edge of the pressure plate is fixedly connected to the crossbar.
[0025] The front and rear dual-station stamping machine also includes a left shaft seat 19 and a right shaft seat 20 disposed on the front side of the lifting seat (in different embodiments, the left shaft seat 19 and the right shaft seat 20 may also be disposed on the rear side of the lifting seat), a left vertical shaft 21 rotatably connected to the left shaft seat, a right vertical shaft 22 rotatably connected to the right shaft seat, and a reducer 23 disposed on the top surface of the lifting seat. The power output shafts of the left vertical shaft, the right vertical shaft and the reducer are connected by a transmission mechanism. The transmission mechanism consists of a synchronous pulley 24 and a synchronous belt 25. In different embodiments, the transmission mechanism may also be a transmission mechanism composed of a sprocket and a chain. The lower ends of the left vertical shaft and the right vertical shaft are respectively provided with cranks 26, and the ends of the cranks are provided with vertical pins 27 that rotate with the crossbar.
[0026] After the encapsulation film punching machine has been working for a period of time, deep cuts will appear on the part of the pressure plate 15 that is directly opposite the die-cutting blade. At this time, it is necessary to change the position of the pressure plate by controlling the reducer 23, so as to offset the cuts on the pressure plate from the die-cutting blade. When the reducer is working, the power output shaft of the reducer 23 rotates. The power output shaft drives the left vertical shaft 21 and the right vertical shaft 22 to rotate synchronously through the transmission mechanism. The left vertical shaft 21 and the right vertical shaft 22 drive the lower crank 26 to rotate, and the crank 26 then drives the horizontal bar 17 to move through the vertical pin 27. The pressure plate 15 connected to the horizontal bar 17 will move synchronously, thereby realizing the adjustment of the pressure plate position. The adjustment is time-saving, labor-saving and highly efficient.
[0027] As an improvement to the above embodiment, a retaining block 29 is connected to the crossbar by screws 28, and the edge of the pressure plate is engaged with the crossbar by the retaining block. This improvement connects the pressure plate 15 via the retaining block 29, making the pressure plate easy to assemble and disassemble.
[0028] As an improvement to the above embodiment, a protective cover 30 for shielding the transmission mechanism is also connected to the top surface of the lifting seat. The protective cover can prevent foreign objects from entering the transmission mechanism and improve the safety of the transmission mechanism during operation.
