TECHNICAL FIELD
[0001] The utility model relates to a dust removal equipment, especially a dust removal equipment for photosensitive film base film. BACKGROUND
[0002] In the production process of photosensitive film base film, the cleanliness of the substrate surface directly affects the quality and performance of the final product. Photosensitive film manufacturers usually need to coat a photosensitive layer on the substrate surface, and any small dust particles can cause uneven coating or defects, thereby affecting the optical performance and reliability of the photosensitive film. Therefore, dust removal on the substrate surface is a key step in the production process.
[0003] Currently, many photosensitive film manufacturers have obvious shortcomings in dust removal on the substrate surface. There is even no special dust removal device on the production line, and only manual wiping or simple blowing operation is relied on. This approach not only has low efficiency, but also is difficult to completely remove small dust particles on the substrate surface. In addition, manual operation can easily introduce new sources of pollution, increasing the product failure rate. Simple dust removal devices are often designed roughly, lacking effective filtration and collection systems, causing dust particles to spread in the workshop, further polluting the production environment, affecting product quality and production efficiency.

[0023] The mounting seat 6 is fixedly arranged on both sides of the front and rear of the cover 5, the dust blowing part 61 is fixedly arranged between the mounting seats 6, the dust blowing part 61 is arranged in an "L" shape, the air blowing part 63 extends into the dust removal cavity of the dust removal box 4, the front and rear parts of the air blowing part 63 are provided with air outlets at intervals, the air blowing port of the front part of the air blowing part 63 is opposite to the dust suction hole of the rear part of the dust removal box 4, and the dust and impurities on the surface of the film material are blown off by high-speed airflow;

[0026] Example 2
[0027] Based on example 1, as shown in Figure 1 and Figure 5 The mounting plate 2 is provided with a fixed block 82 on both sides of the right part, and an adsorption plate 821 is installed between the fixed blocks 82. Shock-absorbing springs 83 are provided on the upper part of the fixed blocks 82, which can absorb the vibration generated by the base film during the material conveying process, reduce the shaking of the base film, and ensure that the base film is more stable during the material conveying process. An electrostatic adsorption accessory 8 is installed between the upper parts of the shock-absorbing springs 83, which is composed of an electrode module and an adsorption platform. Both the adsorption platform and the adsorption plate 821 are provided with a conductive layer, which can generate an electrostatic field to adsorb small particles on the surface of the base film, effectively removing dust and impurities on the base film. There is a material conveying interval between the adsorption platform and the adsorption plate 821. After passing through the dust removal cylinder 3, the base film is introduced into the material conveying interval between the adsorption platform and the adsorption plate 821 through the material conveying cylinder 84. The setting of the material conveying cylinder 84 allows the base film to smoothly enter the material conveying interval, while reducing the friction between the base film and the material conveying cylinder 84, protecting the surface of the base film from damage.
[0028] The upper part of the mounting plate 2 is vertically provided with an electric cylinder 81, and the driving rods of the two electric cylinders 81 on the front and back sides are connected to the upper part of the electrostatic chuck 8 on the front and back sides, respectively. The electrostatic chuck 8 is driven to move up and down by the electric cylinder 81, so as to realize the electrostatic adsorption and release of the base film. When the base film enters the material conveying interval, the electric cylinder 81 drives the electrostatic chuck 8 to move downward, the electrostatic chuck 8 contacts the base film, and the electrostatic adsorption principle is used to efficiently capture the tiny particles on the surface of the base film, so as to pre-treat most of the dust and impurities easily falling off from the base film, and effectively reduce the load in the subsequent dust removal process. When the base film leaves the material conveying interval, the electric cylinder 81 drives the electrostatic chuck 8 to move upward, and the base film is released, so as to ensure that the base film remains stable during the material conveying process, avoid deviation and wrinkles, improve the processing precision and product quality, which not only improves the dust removal efficiency, but also reduces the working strength of the dust blowing device, and prolongs the service life of the equipment.
[0029] In addition, as shown in Figure 3 , the side of the limiting plate 62 is provided with a blowing device 63, the blowing device 63 is provided with a gas connector, and the lower part of the blowing device 63 is provided with a plurality of blowing ports, which are all directed to the side of the dust blowing device 61. The airflow blown by the blowing ports can blow the film material to vibrate slightly, which helps to loosen the fine dust and impurities attached to the surface of the film material, so that they are more easily blown by the high-speed airflow of the dust blowing device 61 to the dust suction hole of the dust removal box 4, further improving the dust removal effect.
[0030] In a more preferred embodiment, as shown in Figure 1 and Figure 4 , the device further comprises a fixing seat 7, a material guiding roller 71, an adjusting rod 72, an adjusting plate 73, and a deviation correction sensor 74. The left part of the dust removal box 4 is provided with the fixing seat 7, and the upper part of the fixing seat 7 is rotatably provided with the material guiding roller 71. After the base film passes between the two roller bodies of the material conveying roller group 21 and enters the left side of the dust removal box 5, the material guiding roller 71 guides the base film to smoothly enter the subsequent processing link, reduces the deviation and wrinkles that may occur during the material conveying process, and ensures the stability of the base film during the material conveying process. The fixing seat 7 is slidably provided with the adjusting rod 72 on the front and back sides, and the adjusting plate 73 is arranged between the adjusting rods. The adjusting rods are arranged to facilitate workers to adjust the relative height of the adjusting plate according to the operation requirements. The adjusting plate 73 is provided with the deviation correction sensor 74 on the front and back sides. The detection head of the deviation correction sensor 74 is directed to the side of the material guiding roller 71, which is used to monitor the position deviation of the base film in real time. Once the base film deviates from the predetermined path, the deviation correction sensor 74 will immediately send a signal to remind the operator to correct the path of the base film, so as to ensure that the base film always advances along the correct route.
[0031] Among them, the adjusting plate 73 is provided with a mounting groove 741, and the deviation correction sensor 74 is slidingly mounted in the mounting groove 741 of the adjusting plate 73, so that the deviation correction sensor 74 can be adjusted according to actual needs, better adapt to base films of different widths, and improve the flexibility and applicability of the equipment.
[0032] The technical principles of the embodiments of the utility model are described above in combination with specific examples. These descriptions are only for explaining the principles of the embodiments of the utility model, and cannot be interpreted as limiting the protection scope of the embodiments of the utility model in any way. Based on the explanations herein, other specific embodiments of the embodiments of the utility model can be conceived by those skilled in the art without creative labor, and these embodiments will all fall within the protection scope of the embodiments of the utility model.
