preheating chamber 1011, a wetting chamber 1012, a drying chamber 1013, a cooling chamber 1014 and a winding chamber 1015 are sequentially arranged in the shell 101 from left to right, wherein the preheating chamber 1011, The temperatures in the wetting chamber 1012 and the drying chamber 1013 rise in order, and the cooling chamber 1014 is provided with a cooling assembly for cooling the photosensitive dry film 100, five chambers in the housing 101 are provided with guide rollers 102 for guiding the photosensitive dry film 100, so that the photosensitive dry film 100 moves gradually from the preheating chamber 1011 in a predetermined direction, and is wound up by a winding device installed in the winding chamber 1015, which is a prior art, so that not described in detail, the guide rollers 102 in the housing 101 are distributed in a "table" shape, the guide rollers 102 in the preheating chamber 1011 and the drying chamber 1013 are all provided with four, and the four guide rollers 102 are located on the same vertical line, the guide rollers 102 in the wetting chamber 1012 and the cooling chamber 1014 are both provided with two, and the two guide rollers 102 are located

wetting chamber 1012 and the cooling chamber 1014 are in a straight trend, so that the photosensitive dry film 100 can undergo longer heating and drying paths in the preheating chamber 1011 and the drying chamber 1013, so that heat can uniformly permeate into each part of the film, and the film is rapidly processed in the wetting chamber 1012 and the cooling chamber 1014, so that long-time stay is avoided, when the existing photosensitive dry film 100 is dried, the solvent on the surface volatilizes faster, the solvent inside the film layer volatilizes slower, so that the internal stress of the film layer accumulates, and further the photosensitive dry film 100 can be warped or deformed, in order to solve the problem, the photosensitive dry film 100 is wound on the guide roller 102 in the shell 101 according to the shape of a straight line, and the photosensitive dry film 100 is driven by the winding device in the winding chamber 1015, so that the photosensitive dry film 100

chamber 1013, so that some moisture on the surface of the photosensitive dry film 100 is removed, the moisture in the photosensitive dry film 100 is driven by the driving force of evaporation and diffusion to migrate from the interior of the film to the surface, the process is relatively mild, the accumulation and the warpage of the surface stress caused by the excessively fast drying of the

performance of the photosensitive dry film 100, but also help to control the internal and external humidity of the photosensitive dry film 100 layer, so that the surface humidity of the film can be greater than the humidity in the film, in the wetting process, moisture gradually permeates into the film from the outside of the film, but the moisture migration speed into the film is slower due to the relatively larger internal structure and density of the film, so that the surface humidity of the film is larger than the humidity of the film inside in the initial stage of the wetting process, and the photosensitive dry film 100 quickly enters the drying chamber 1013 to be dried at high temperature due to the short path of the wetting chamber 1012, so that the film is kept in the initial stage of wetting, thereby avoiding damage in the subsequent heating and drying processes, the photosensitive dry film 100 moves to the drying chamber 1013 to be subjected to high temperature treatment

treatment in the drying chamber 1013, the photosensitive dry film 100 moves to the cooling chamber 1014 to be subjected to the cooling treatment in the cooling chamber 1014, the cooling treatment can rapidly cool the photosensitive dry film 100 to room temperature or a temperature suitable for subsequent operation, can prevent thermal stress from generating, and reduce deformation or damage of film materials, so that the drying effect can be effectively improved through a plurality of stage treatment modes, and the photosensitive dry film 100 is prevented from being warped or deformed due to the fact that the moisture on the surface volatilizes faster and the moisture inside the film volatilizes slower in the high-temperature drying process of the photosensitive dry film 100, so that

Further, the cooling assembly comprises a frame body 501 fixedly connected to the outer wall of the cooling chamber 1014, a shutter 502, a dust-proof plate 503, a drying plate 504, a condensing tube 505 and a second induced draft fan 506 are sequentially installed in the frame body 501 from the outer side of the housing 101 to the inner side, a condenser 509 is installed on the outer side wall of the housing 101, the condenser 509 is connected with the condensing tube 505 through a pipeline, the cooling assembly further comprises inclined blocks 507 symmetrically fixedly connected to the inner wall of the cooling chamber 1014, the inclined blocks 507 are arranged at the film outlet of the cooling chamber 1014 up and down, in the direction from the film inlet to the film outlet, the distance between the sides of the two inclined blocks 507 close to each other is gradually reduced, namely, the distance between the sides of the two inclined blocks 507 close to each other is gradually reduced from left to right, a third induced draft fan 508 is installed in the rolling chamber 1015, and the air of the cooling chamber 1014 and the rolling chamber 1015 flows mutually, thus the second induced draft fan 506, the condensing tube 505 and the third induced draft fan 508 are started, the second induced draft fan 506 introduces external air into the cooling chamber 1014, removes dust through the dust-proof plate 503, removes water from the drying plate 504, then exchanges heat with the condensing tube 505, the condensing tube 505 absorbs heat, the air releases heat to form cold air, and then the cold air can be blown into the cooling chamber 1014, meanwhile, the cold air flows from the cooling chamber 1014 to the winding chamber 1015 through the third induced draft fan 508, and the flow path and speed of the cold air in the cooling chamber 1014 are changed due to the turbulence of the inclined block 507 in the flowing process, thereby causing non-uniformity of temperature distribution in the cooling chamber 1014, namely forming a cooled temperature gradient, when the photosensitive dry film 100 just enters the film inlet of the cooling chamber 1014, the temperature is highest, when the photosensitive dry film 100 gradually moves towards the film outlet, the temperature gradually decreases, and when the photosensitive dry film 100 is at the film outlet of the cooling chamber 1014 is lowest, this helps to avoid thermal stress due to too rapid cooling, and ensures the quality of the photosensitive dry film 100.
Still further, because the photosensitive dry film 100 in the preheating chamber 1011 and the drying chamber 1013 needs to move for a long distance, the photosensitive dry film 100 may deviate during the moving process, in order to solve the problem, the device further comprises a limiting component, the limiting component comprises a mounting plate 401 mounted on the sealing plate 306, a second mounting frame 402 is mounted on the mounting plate 401, the second mounting frame 402 is rotationally connected with a detecting roller 403, a rotation detector 404 is mounted on a rotation shaft of the detecting roller 403, when the sealing plate 306 moves, the second mounting frame 402 is driven to move, so that the detecting roller 403 is close to the photosensitive dry film 100, if the photosensitive dry film 100 deviates, the photosensitive dry film 100 drives the detecting roller 403 to rotate, and then is detected by the rotation detector 404, and then a worker can be notified to process.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
