Description

Technical Field

[0001] This utility model relates to the field of film application technology, specifically to a vacuum adsorption type correction device for bottom film application. Background Technology

[0002] In the bottom lamination process of industries such as electronics, packaging, and batteries, the film substrate often needs to be precisely bonded to other components or rolled up and unrolled. For example, in battery production, the bonding of the bottom film to the film to be laminated, and the application of bottom protective film on the surface of electronic components. These scenarios have extremely high requirements for the edge neatness and positional accuracy of the film. Once the bottom lamination process is offset, it will not only cause material waste and increase the defect rate, but may also affect the normal progress of subsequent cutting, lamination and other processes, and even lead to performance defects in the end product.

[0003] In existing technologies, mechanical alignment often uses a cylinder to drive the alignment roller to swing or move laterally, relying on physical contact to adjust the film position. This method makes it difficult to precisely control the pressure of the bottom film, and when the tension is unstable, it is easy to cause scratches on the film surface and local stretching deformation. At the same time, due to the influence of manufacturing and installation precision, the parts wear out after the equipment is used for a long time, and the alignment error will further increase, making it difficult to meet the requirements of high-precision film application.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figures 1-5 As shown, the vacuum adsorption type correction device with bottom film of this utility model includes a vacuum adsorption roller 1, and a correction mechanism 2 is provided at the bottom of the vacuum adsorption roller 1.

[0026] The correction mechanism 2 includes a support plate 6, which supports the connecting pipes 4 on both sides, thereby supporting the vacuum adsorption roller 1 and enabling it to rotate normally. The upper middle part of both sides of the support plate 6 is rotatably connected to the connecting pipes 4, which are respectively rotatably connected to the middle of the left and right side walls of the vacuum adsorption roller 1. The outer wall of the vacuum adsorption roller 1 is provided with multiple sets of evenly distributed adsorption holes 3, which can adsorb the surface of the bottom film and prevent wrinkles from forming on the bottom film. A threaded plate 7 is fixedly connected to the middle of the bottom wall of the support plate 6. The threaded plate 7 is threadedly connected to the outside of the adjusting screw 8. The adjusting screw 8 is rotatably connected between two sets of fixed plates 10. During the rotation of the adjusting screw 8, the threaded plate 7 can move left and right on its outside to correct the bottom film. The fixed plates 10 are respectively fixedly connected to the left and right ends of the middle of the top wall of the bottom plate 11.

[0027] The left end of the left connecting pipe 4 is rotatably connected to the negative pressure pipe 19, and the right end of the right connecting pipe 4 is fixedly connected to the sealing block 5. The sealing block 5 seals the right connecting pipe 4, so that the vacuum adsorption roller 1 can function normally. The end of the negative pressure pipe 19 away from the vacuum adsorption roller 1 is fixedly connected to the output end of the vacuum pump 22. A pressure regulating valve 20 is provided on the outer side of the negative pressure pipe 19 near the vacuum adsorption roller 1. The pressure regulating valve 20 can adjust the adsorption intensity of the vacuum adsorption roller 1.

[0028] A vacuum filter 21 is installed in the middle of the outer side of the negative pressure pipe 19. The vacuum filter 21 is located between the vacuum pump 22 and the pressure regulating valve 20. A drive motor 9 is fixedly connected to the middle of the right side wall of the right fixed plate 10. The output end of the drive motor 9 is fixedly connected to the adjusting screw 8. During the operation of the drive motor 9, it can drive the adjusting screw 8 to rotate, which is the power component of the correction device.

[0029] A base 12 is fixedly connected to each of the four corners of the bottom wall of the base plate 11. A connecting plate 13 is fixedly connected to the left and right ends of the front top of the base plate 11. A limit rod 14 is fixedly connected between the middle and lower parts of the two sets of connecting plates 13. A slider 15 is slidably connected through the outside of the limit rod 14. The slider 15 can move left and right outside the limit rod 14 to adjust the position of the photoelectric edge sensor 18 to adapt to the bottom film correction operation of different specifications.

[0030] A fixing block 17 is fixedly connected to the top of the slider 15. A photoelectric edge sensor 18 is fixedly connected to the right side of the fixing block 17. A servo cylinder 16 is fixedly connected to the upper left side of the left connecting plate 13. The output end of the servo cylinder 16 is fixedly connected to the slider 15. During the operation of the servo cylinder 16, the extension and retraction of the output end can make the slider 15 and the top photoelectric edge sensor 18 move left and right.

[0031] Working principle: During operation, the vacuum pump 22 is started first. Its output end delivers negative pressure to the internal cavity of the vacuum adsorption roller 1 through the negative pressure pipe 19. The vacuum filter 21 on the negative pressure pipe 19 intercepts impurities such as film debris and environmental dust to prevent clogging of the adsorption holes 3 of the vacuum adsorption roller 1 and damage to the vacuum pump 22. The pressure regulating valve 20 can precisely adjust the negative pressure value according to the characteristics of the film material. The vacuum adsorption roller 1 is rotatably connected to the support plate 6 through the connecting pipes 4 on the left and right sides. The left connecting pipe 4 is rotatably connected to the negative pressure pipe 19, and the right connecting pipe 4 is sealed by the sealing block 5 to ensure the internal seal of the roller. When the bottom film passes through the vacuum adsorption roller 1, the adsorption holes 3 evenly distributed on the outer wall of the roller generate a stable negative pressure, tightly adsorbing the film material onto the roller surface, preventing slippage, displacement, or wrinkling during transport. Simultaneously, the photoelectric edge sensor 18 is installed on the top of the slider 15 through the fixing block 17. The slider 15 is sleeved on the limiting rod 14 between the two sets of connecting plates 13. The cylinder 16 can push the slider 15 to slide along the limit rod 14 to adjust the position of the photoelectric edge sensor 18, so that it is accurately aligned with the edge of the membrane material and collects position signals in real time. After the signal is transmitted to the control system, the system compares the actual position with the preset standard position to determine the offset. If an offset is determined, a command is sent to the drive motor 9 fixed on the right fixed plate 10. The drive motor 9 drives the adjusting screw 8, which is rotatably connected between the two sets of fixed plates 10, to rotate. The threaded plate 7, which is threadedly connected to the adjusting screw 8, is fixed in the middle of the bottom wall of the support plate 6 to convert the rotational motion into linear motion, which drives the support plate 6 and the vacuum adsorption roller 1 connected to it to move smoothly laterally, thereby accurately compensating for the offset of the membrane material. After the photoelectric edge sensor 18 detects that the membrane material has returned to the standard position, the control system issues a stop command to complete one correction cycle. Throughout the process, the base plate 11 and the bottom base 12 provide stable support for the device to ensure that all components operate in coordination.
