Description

Technical Field

[0001] The utility model belongs to the technical field of solar screen coating, and in particular relates to a screen photosensitive adhesive coating device. Background Art

[0002] When making a screen, multiple processes such as stretching the screen, gluing, printing, exposing, and cleaning are usually required. Gluing involves applying photosensitive glue on the screen, and the thickness of the photosensitive glue at every location on the screen should be uniform and consistent to avoid quality problems. A coating device for processing solar printing screens is disclosed in the prior art, with document number CN217856975U. This solution prevents glue from condensing into lumps by cooperating with a coating mounting frame structure, a coating shifting structure, a coating structure, and a linkage extrusion structure. The first and second grinding rollers rotate inwardly to squeeze and rub the dripping glue, preventing the formation of small lumps and thus eliminating quality problems in solar screen coating.

[0003] The above solution can prevent the glue from condensing and forming lumps, which may cause the device to stop or be damaged. However, in order to ensure that every position on the screen is evenly covered with glue, the amount of glue dripping on the screen is more than the actual required amount. This excess glue will reduce the efficiency of subsequent processes. During the exposure process, the excess glue will extend the exposure time required, and it will also increase the difficulty of cleaning the screen, reducing the overall efficiency of screen production.

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents selected embodiments of the present application.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0024] See Figures 1 to 2 As shown, a device for applying photosensitive glue to a screen comprises a horizontally arranged screen fixing table 1, a positioning device 2 is provided on the screen fixing table 1, the screen can be placed in the positioning device 2, and the positioning device 2 will fix the screen; the screen fixing table 1 is also connected to a movable device 3 that can be raised and lowered, and the movable device 3 is cooperated with a glue coating device 4, which can move along the length direction of the movable device 3 to evenly apply photosensitive glue to the screen in the positioning device 2, and at the same time, a residual glue cleaning component 5 is also provided on the movable device 3. After the glue coating device 4 completes the application of photosensitive glue to the screen, the glue coating device 4 will contact the residual glue cleaning component 5, and the residual glue cleaning component 5 will cooperate with the glue coating device 4 to remove excess photosensitive glue from the screen, so as to avoid increasing the drying and cleaning time and reducing the plate making efficiency in the subsequent plate exposure and cleaning processes.

[0025] See Figure 3 As shown, the positioning device 2 includes a horizontal fastener, which can stably clamp the screen, and the horizontal fastener is slidably connected to the screen fixing platform 1. Specifically, the horizontal fastener includes two vertical ear plates 6, which are symmetrically arranged on the screen fixing platform 1. The upper surface of the screen fixing platform 1 is symmetrically provided with fastening slide grooves 7. The lower ends of the vertical ear plates 6 are slidably connected to the corresponding fastening slide grooves 7. Displacement screws 8 are provided on the outer sides of the vertical ear plates 6. One end of the displacement screw 8 is movably connected to the vertical ear plates 6, and the other end is a free end. A threaded collar 9 is provided on the screen fixing platform 1, and the threaded collar 9 is fixed to the screen fixing platform 1. The free end of the displacement screw 8 passes through the threaded collar 9 and is threadedly connected to the threaded collar 9. The distance between the two vertical ear plates 6 can be adjusted by screwing the displacement screw 8.

[0026] At this time, a flat washer 10 is provided on the inner side wall of the vertical ear plate 6. When placing the screen, the screen is placed between the two vertical ear plates 6, with the flat washer 10 located below the screen and in contact with the screen. Then, the displacement screw 8 is screwed to move the two vertical ear plates 6 closer to each other until both ends of the screen contact the inner side wall of the vertical ear plates 6 on the corresponding side, thereby forming a stable clamping for the screen. At the same time, as the two vertical ear plates 6 approach each other, the contact area between the flat washer 10 and the screen increases, and the supporting force on the screen is also correspondingly enhanced, thereby achieving stable clamping of the screen and preventing the screen from shaking significantly during the gluing process.

[0027] See Figures 4 to 6 As shown, the gluing device 4 is matched with the moving device 3, and the length direction of the moving device 3 is parallel to the length direction of the screen. When the gluing device 4 moves along the moving device 3, the screen can be glued. The gluing device 4 specifically includes a glue box 11 and a scraper 12. The upper surface of the glue box 11 is provided with a glue inlet 13, and photosensitive glue can be added to the glue box 11 through the glue inlet 13. A glue pressing plate 14 is placed in the glue box 11, and a hand grip 15 is connected to the glue pressing plate 14. The upper end of the hand grip 15 passes through the glue inlet 13, and a cover 16 is screwed on the glue inlet 13. A circular hole is provided at the center of the cover 16, and the upper end of the hand grip 15 passes through the circular hole. Covering the cover 16 can maintain the humidity and viscosity of the photosensitive glue. If photosensitive glue needs to be added, unscrew the cover 16. ; The scraper 12 is connected to the lower surface of the glue box 11, and the lower surface of the glue box 11 is fitted on the mobile device 3. A strip nozzle 17 is connected to the lower surface of the glue box 11. The strip nozzle 17 is located on one side of the scraper 12 and is parallel to the scraper 12. The strip nozzle 17 is connected to the glue box 11. An electric push rod 18 is connected to one side of the glue box 11. The direction of extension and retraction of the electric push rod 18 is consistent with the length direction of the mobile device 3. The electric push rod 18 is fixed on the mobile device 3. The electric push rod 18 can be used to control the glue box 11 to move along the mobile device 3. During the movement, the hand-held rod 15 drives the glue pressing plate 14 to squeeze the photosensitive glue, and the photosensitive glue can flow out of the strip nozzle 17 and fall on the screen below. The scraper 12 synchronously applies the photosensitive glue evenly.

[0028] The mobile device 3 is connected to the screen fixing platform 1 via an electric telescopic rod 19. The electric telescopic rod 19 is vertically fixed to the screen fixing platform 1 and is located on the outside of the two vertical ear plates 6. The mobile device 3 is arranged above the vertical ear plates 6. Both ends of the mobile device 3 are connected to the telescopic ends of the electric telescopic rod 19. According to the different thicknesses of the screens, the horizontal height of the mobile device 3 can be adjusted by the electric telescopic rod 19 to ensure that the scraper 12 is in contact with the screen, thereby avoiding the situation in which the scraper 12 cannot contact the screen or the scraper 12 is too close to the screen during the gluing process, thereby avoiding the screen being scratched;

[0029] The moving device 3 includes two end plates 20 and a right-angle rail 21. The two end plates 20 are respectively connected to the electric telescopic rods 19 on both sides. The two right-angle rails 21 are connected in parallel between the two end plates 20 and are in the same horizontal plane. The end of each right-angle rail 21 is docked with the end of the corresponding end plate 20, and the right-angle rail 21 is perpendicular to the end plate 20. There is a gap between the two right-angle rails 21. The glue box 11 is slidably connected to the right-angle rail 21. The scraper 12 is located in the gap between the two right-angle rails 21. When the glue box 11 slides back and forth along the right-angle rail 21, the scraper 12 moves accordingly to coat the screen. When the scraper 12 moves to both ends of the screen, the scraper 12 will come into contact with the residual glue cleaning member 5, which is connected to the right-angle track 21 and is located above the end of the screen. When the electric telescopic rod 19 controls the moving device 3 to rise and fall vertically, the residual glue cleaning member 5 moves accordingly until the scraper 12 contacts the screen surface for glue coating. At this time, the residual glue cleaning member 5 also moves to contact the screen surface; when the screen finishes gluing, the electric push rod 18 controls the scraper 12 to push the excess photosensitive glue to the end of the screen. At this time, the residual glue cleaning member 5 and the scraper 12 cooperate to remove the residual glue from the screen. Specifically:

[0030] The residual glue cleaning member 5 is provided with two, and the two residual glue cleaning members 5 are symmetrically arranged on the right-angle track 21. The residual glue cleaning member 5 includes a hanging arm 22 and a scraping glue piece 23. The bottom surfaces of the two right-angle tracks 21 are connected with the hanging arm 22. The upper end of the hanging arm 22 is fixedly connected to the right-angle track 21, and the lower end of the hanging arm 22 is connected with the scraping glue piece 23. One side of the scraping glue piece 23 is an inclined surface, which is convenient for scraping glue. The scraping glue piece 23 is located between the two hanging arms 22. A residual glue storage shell 24 is detachably connected to one side of the scraping glue piece 23. When the bottom surface of the scraping glue piece 23 contacts the screen, the bottom surface of the residual glue storage shell 24 also contacts the screen. The scraper 12 can directly push the residual glue into the residual glue storage shell 24; the residual glue storage shell 24 includes a flat plate 25. When the residual glue storage shell 24 moves down with the moving device 3 to contact the screen, the bottom surface of the flat plate 25 will contact the screen. Side sealing plates 26 are vertically connected to both ends of the flat plate 25. The side sealing plates 26 are right-angled triangles. A vertical baffle 27 is connected between the two side sealing plates 26. The vertical baffle 27 is also connected to the flat plate 25. The flat plate 25, the side sealing plates 26 and the vertical baffle 27 together constitute the residual glue storage shell 24, in which the flat plate 25 is detachably connected to the scraping blade 23;

[0031] When making the plate, the screen is stably clamped by the positioning device 2, and then the moving device 3 is controlled by the electric telescopic rod 19 to move vertically downward until the scraper 12 contacts the screen and the screen is coated with glue. In this process, the residual glue cleaning component 5 also moves downward. When the scraper 12 contacts the screen, the scraping film 23 and the residual glue storage shell 24 also contact the screen. After the scraper 12 finishes coating the glue, the scraper 12 is controlled to push the residual glue on the surface of the screen to the two ends of the screen. When the scraper 12 contacts the scraping film 23, the scraper 12 can move along the inclined surface of the scraping film 23. The residual glue is pushed onto the flat plate 25, and then the scraper 12 is controlled by the electric push rod 18 to move to separate from the residual glue cleaning component 5. At this time, the moving device 3 is controlled to move upward by the electric telescopic rod 19 to separate the scraper 12 and the scraper film 23 from the screen. When the scraper film 23 is separated from the screen, the residual glue storage shell 24 axially connected to the scraper film 23 will be overturned by gravity, and the residual glue will flow between the vertical baffle 27 and the flat plate 25. Then the residual glue storage shell 24 can be disassembled and the residual glue can be reused to avoid waste of photosensitive glue.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based primarily on the scope of protection of the claims.
