A thin film adsorption positioning device for thin film production and processing

Abstract

This utility model discloses a film adsorption and positioning device for film production and processing, including a funnel-shaped cover and an adsorption structure installed at the bottom. The adsorption structure includes a partition. The bottom of the funnel-shaped cover is open and equipped with a partition. The partition has a number of circular cavities arranged in a matrix. A funnel sleeve is fixedly connected to the inner side wall of the circular cavity. A circular plate is located at the center of the funnel sleeve. A pad is fixedly connected to the center of the top of the circular plate. A number of L-shaped connecting rods are fixedly connected to the outer side wall of the top of the pad. The vertical ends of the L-shaped connecting rods are fixedly connected to the top of the partition. The film adsorption process does not use the traditional direct adsorption through circular holes, which makes it less likely for local areas of the film to be adsorbed into the holes. This improves the conformability of the film after adsorption and reduces the likelihood of wrinkles. At the same time, this unique adsorption structure avoids damage to the film caused by excessive local stress, thus improving the quality and yield of film processing.

Description

Technical Field

[0001] This utility model relates to the field of thin film production and processing technology, specifically to a thin film adsorption and positioning device for thin film production and processing. Background Technology

[0002] In the thin film production process, adsorption positioning is a crucial step. Its main functions include: creating a vacuum environment through adsorption to ensure that the thin film can remain stably on the substrate surface, thus laying the foundation for subsequent processing steps such as thin film cutting.

[0003] If multiple holes are made on the traditional thin film adsorption substrate for direct adsorption, it is easy to cause local bulges in the film, or even wrinkles in local areas, which will affect the overall quality of the product. Utility Model Content

[0004] The purpose of this invention is to provide a film adsorption positioning device for film production and processing that avoids damage to the film caused by excessive local stress, and improves the quality and yield of film processing, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a film adsorption and positioning device for film production and processing, comprising a funnel-shaped cover and an adsorption structure installed at the bottom of the inner part. The adsorption structure includes a partition. The bottom of the funnel-shaped cover is open and is equipped with a partition. The partition has a plurality of circular cavities arranged in a matrix. A funnel sleeve is fixedly connected to the inner side wall of the circular cavity. A circular plate is provided at the center of the funnel sleeve. A pad is fixedly connected to the center of the top of the circular plate. A plurality of L-shaped connecting rods are fixedly connected to the outer side wall of the top of the pad. The vertical ends of the L-shaped connecting rods are fixedly connected to the top of the partition. A material pushing structure is provided on the funnel-shaped cover.

[0006] Preferably, the top of the funnel-shaped cover is connected to an outer pipe, and a solenoid valve is installed on the outer pipe. Several L-shaped mounting plates are fixedly connected to the two outer sides of the funnel-shaped cover, and mounting holes are opened on the horizontal surface of the L-shaped mounting plates.

[0007] Preferably, several reserved parts are fixedly connected to both sides of the inside of the bucket-shaped cover. The reserved parts have threaded holes inside, and the partition plate has matching countersunk holes.

[0008] Preferably, the outer diameter of the circular plate is smaller than the outer diameter of the bottom of the funnel sleeve, and the outer diameter of the pad is smaller than the outer diameter of the top of the funnel sleeve.

[0009] Preferably, the pushing structure includes a cylinder, and the bottom of the funnel sleeve is provided with two push plates arranged side by side. Two diagonally distributed cylinders are installed on the rear end face of the funnel-shaped cover. The output end of one cylinder is fixedly connected to a push plate through an L-shaped connecting plate, while the output end of the other cylinder is fixedly connected to another push plate through a long strip connecting plate.

[0010] Preferably, the front end face of the funnel-shaped cover is fixedly connected to a slide rail, and two sliders are slidably connected at the center of the slide rail. The bottom of the sliders is connected to the adjacent push plate through a fixed rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the film adsorption process does not use the traditional direct adsorption through round holes, which makes it less likely for local areas of the film to be adsorbed into the pores, thus improving the conformability of the film after adsorption and reducing the likelihood of wrinkles. At the same time, this unique adsorption structure avoids damage to the film caused by excessive local stress, improving the quality and yield of film processing. In actual operation, the pressure inside the funnel-shaped cover can be flexibly controlled by adjusting the pumping rate of the external vacuum equipment, thereby precisely adjusting the magnitude of the adsorption force to meet the processing needs of films of different thicknesses and materials. In addition, the design of this device also takes into account the characteristics of easy cleaning and maintenance. Both the funnel-shaped cover 1 and the adsorption structure 2 can be easily disassembled, facilitating regular cleaning and replacement of parts, ensuring the long-term stable operation of the device.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 4The figure shows a film adsorption and positioning device for film production and processing, including a funnel-shaped cover 1 and an adsorption structure 2 installed at the bottom. The adsorption structure 2 includes a partition 21. The bottom of the funnel-shaped cover 1 is open and the partition 21 is installed. The partition 21 has a number of circular cavities 28 distributed in a matrix. The inner side wall of the circular cavity 28 is fixedly connected to a funnel sleeve 22. A circular plate 23 is provided at the center of the funnel sleeve 22. A pad 25 is fixedly connected at the top center of the circular plate 23. A number of L-shaped connecting rods 24 are fixedly connected to the top of the pad 25. The vertical ends of the L-shaped connecting rods 24 are fixedly connected to the top of the partition 21. A pushing structure 3 is provided on the funnel-shaped cover 1.

[0016] It is worth noting that when the entire funnel-shaped cover 1 is installed on the film conveyor belt production line, and the entire outer pipe 6 is connected to the external vacuum equipment, the process of opening the solenoid valve 5 can extract the gas inside the funnel-shaped cover 1. Due to the pressure difference between the inside and outside, an adsorption force will be generated in the annular gap between the funnel sleeve 22 and the circular plate 23, so that the film is adsorbed and fixed, completing the subsequent production process such as cutting. The adsorption does not use the traditional direct adsorption through a circular hole, resulting in high conformity and no wrinkles. At the same time, this unique adsorption structure avoids damage to the film caused by excessive local stress, improving the quality and yield of film processing. In actual operation, by adjusting the pumping rate of the external vacuum equipment, the pressure inside the funnel-shaped cover 1 can be flexibly controlled, thereby precisely adjusting the magnitude of the adsorption force to adapt to the processing needs of films of different thicknesses and materials. In addition, the design of this device also takes into account the characteristics of easy cleaning and maintenance. Both the funnel-shaped cover 1 and the adsorption structure 2 can be easily disassembled, facilitating regular cleaning and replacement of parts, ensuring the long-term stable operation of the device.

[0017] Please see Figure 1 and Figure 2 The top of the funnel-shaped cover 1 is connected to an outer pipe 6, on which a solenoid valve 5 is installed. Several L-shaped mounting plates 4 are fixedly connected to the two outer sides of the funnel-shaped cover 1. The horizontal plane of the L-shaped mounting plates 4 has mounting holes 41, which allow the funnel-shaped cover 1 to be securely installed on the film conveyor belt production line, ensuring the stability of the entire device during operation. The inside of the funnel-shaped cover 1 is designed with a funnel sleeve 22 and a circular plate 23, forming an annular gap between them. When the external vacuum equipment extracts the gas inside the funnel-shaped cover 1 through the outer pipe 6 and the solenoid valve 5, an adsorption force is generated at the annular gap, achieving effective adsorption and fixation of the film.

[0018] Please refer to Figure 4Several pre-reserved parts 26 are fixedly connected to both sides of the inner side of the bucket-shaped cover 1. The pre-reserved parts 26 have threaded holes 27 inside. The partition plate 21 has matching countersunk holes 29. By installing bolts that are compatible with the threaded holes 27 in the countersunk holes 29, the partition plate 21 can be firmly installed inside the bucket-shaped cover 1. This installation method is not only simple in structure, but also facilitates the disassembly and replacement of the partition plate 21 and regular cleaning.

[0019] See Figure 1 and Figure 4 The outer diameter of the circular plate 23 is smaller than the outer diameter of the bottom of the funnel sleeve 22, and the outer diameter of the pad 25 is smaller than the outer diameter of the top of the funnel sleeve 22. This dimensional design ensures appropriate gaps between the circular plate 23 and the bottom of the funnel sleeve 22, and between the pad 25 and the top of the funnel sleeve 22, allowing gas to flow smoothly through the annular gaps, thus guaranteeing a uniform and stable adsorption force during vacuuming. Simultaneously, the pad 25 also supports the circular plate 23, preventing deformation or displacement during long-term use, further improving the reliability and service life of the entire device.

[0020] See 2 and Figure 3 The pushing structure 3 includes a cylinder 31. Two push plates 34 are arranged side-by-side at the bottom of the funnel sleeve 22. Two diagonally distributed cylinders 31 are installed on the rear end face of the funnel-shaped cover 1. The output end of one cylinder 31 is fixedly connected to one push plate 34 via an L-shaped connecting plate 32, while the output end of the other cylinder 31 is fixedly connected to the other push plate 34 via a long strip connecting plate 33. When the adsorption process stops, the film remains adhered to the bottom of the partition 21. When the two cylinders 31 operate synchronously, they can drive the two push plates 34 to move towards or away from each other at the bottom of the funnel sleeve 22. This design allows the pusher structure 3 to move the push plates 34 horizontally according to actual production needs, thereby separating the adhered film. After separation, the cylinders 31 drive the push plates 34 back to their original positions, waiting for the next pushing operation. In addition, the surface of the push plates 34 is covered with a rubber sleeve, which has smooth and wear-resistant properties, reducing friction with the film and preventing damage to the film during pushing. It eliminates the need for manual separation of the adsorbed film, improving work efficiency.

[0021] Please see Figure 2 and Figure 3The front end of the funnel-shaped cover 1 is fixedly connected to a slide rail 37. Two sliders 35 are slidably connected at the center of the slide rail 37. The bottom of the sliders 35 is connected to the adjacent push plate 34 through a fixed rod 36. In actual operation, when the cylinder 31 drives the push plate 34 to move in opposite directions, the sliders 35 will slide synchronously on the slide rail 37 as the push plate 34 moves. This sliding connection design not only provides a stable guide for the movement of the push plate 34, ensuring that the push plate 34 can move accurately according to the predetermined trajectory, but also avoids deviation or jamming, thereby ensuring the accuracy and stability of the separation film operation.
