Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust removal, in particular to a protection structure in the production process of a film for an etched plate. Background Technique
[0002] In the process of producing metal products, many products need to etch the metal surface. Before etching such products, the surface of the workpiece needs to be exposed to make a printing plate, developed, and then the protective film in the area to be etched is removed. When etching, it contacts chemical solutions to achieve the effect of dissolution and corrosion, forming concave-convex or hollow-shaped effects. In the above plate-making and developing process, a film negative is required. In the production process of the film negative, the presence of extremely small dust is very likely to scratch the film negative, resulting in the film negative being unable to be used in the subsequent exposure process. For this reason, a sticky dust roller is used to remove dust from both sides of the film negative, and then a PE protective film is covered on the film negative to prevent the surface of the film negative from being scratched. However, the film negative is relatively fragile, and the extrusion force when the sticky dust roller removes dust needs to be accurately controlled, otherwise the film negative will be damaged.

Specific Embodiments
[0013] In order to deepen the understanding and recognition of the present utility model below, the technical solutions in the embodiments of the present utility model will be clearly and completely described and introduced in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments, and no any form of limitation is imposed on this embodiment. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0014] Please refer to Figure 1-2, the present utility model provides a technical solution: a protection structure during the production of a film for an etched plate, including a conveying table 1, a fixed frame 2 fixedly connected to the middle of the conveying table 1. The fixed frame 2 is of a U-shaped structure. A sliding plate 3 is slidably connected to the middle of the fixed frame 2. A dust-removing roller 4 is rotatably connected to the middle of the sliding plate 3. A traction plate 12 is fixedly connected to the upper end of the sliding plate 3. An installation plate 6 is fixedly connected to the right inner wall of the fixed frame 2. The installation plate 6 is of a U-shaped structure. A control board 7 is provided in the middle of the installation plate 6. A magnetic attraction member 11 is fixedly connected to the lower end of the control board 7. An adjusting screw 5 is fixedly connected to the upper inner wall of the fixed frame 2. An upper limiting plate 15 and a lower limiting plate 14 are threadedly connected to the middle of the adjusting screw 5. Conductive rings 17 are rotatably connected to the side ends of the upper limiting plate 15 and the lower limiting plate 14.
[0015] An isolation cylinder 9 is fixedly connected to the lower inner wall of the installation plate 6. An electromagnet 10 is fixedly connected to the inside of the isolation cylinder 9. The lower end of the magnetic attraction member 11 is inserted into the isolation cylinder 9. A reset spring 8 is fixedly connected between the upper end of the control board 7 and the inner wall of the installation plate 6. The adsorption force of the electromagnet 10 on the magnetic attraction member 11 is greater than the spring force. When the electromagnet 10 is energized, the electromagnet 10 attracts the magnetic attraction member 11, causing the control board 7 to be located at the lower limiting plate 14. The control board 7 is sleeved on the adjusting screw. The left side of the control board 7 is fixedly connected to the traction plate 12. The control board 7 is located between the upper limiting plate 15 and the lower limiting plate 14. Conductive contacts 16 are fixedly connected to both the upper end face and the lower end face of the control board 7. A warning lamp 13 is fixedly connected to the right side of the control board 7. The warning lamp 13 is electrically connected to the conductive contacts 16. According to the thickness of the film negative and the PE protective film, the distance between the upper limiting plate 15 and the lower limiting plate 14 is changed. First, the control board 7 is located at the lower limiting plate 14, and the dust-removing roller removes dust from one side of the film negative. Then, the PE protective film is covered on the film negative, and then the film negative is turned over. At this time, the electromagnet 10 is powered off, and under the action of the reset spring 8, the control board 7 moves upward, so that the conductive contact 16 at the upper end of the control board 7 abuts against the conductive ring 17 on the upper limiting plate 15. At this time, the alarm lamp 13 lights up, so as to remove dust from the other side of the film negative. When the PE protective film is added to the film negative, the extrusion force of the dust-removing roller 4 can be accurately controlled to avoid damaging the film negative.
[0016] The dust removal protection steps are as follows:
[0017] 1) By using an ion air gun to blow the surface of the negative film, dust particles with a larger diameter are removed;
[0018] 2) Then use a clean dust-removing roller to clean the fine dust particles on one side of the film negative;
[0019] 3) After the above steps (1) and (2), a PE protective film with a thickness of 0.05 mm and a width that can cover the entire film negative is covered on the film negative to prevent the surface of the negative from being scratched;
[0020] 4) After completing the above step (3), turn over the film negative and repeat steps (1) and (2);
[0021] 5) After completing the above step (4), since the PE protective film has no adhesiveness with the PET substrate, a PP protective film with a thickness of 0.05 mm and a width that can cover the entire film negative is used to cover the substrate surface of the negative to prevent the substrate surface of the negative from being scratched.
[0022] Although the embodiments of the present invention have been shown and described, it should be emphasized that the above description is only an introduction and description of the usage mode of the embodiments of the present invention, and does not impose any formal limitation on the present invention. For those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
