[0002] The dispensing process for computer keyboard panels is a crucial step in keyboard manufacturing, primarily used to secure components such as the keyboard frame, keycaps, and membrane circuit boards.

[0003] The dispensing curing device described in announcement number CN221847668U includes a base, a U-shaped frame, and a push rod. A rotating block is fixedly connected to the bottom of the push rod, and a rotating support column is fixedly connected to one side of the rotating block. A support plate is sleeved on the outside of the rotating support column, and a needle is rotatably connected to one side of the support plate. A needle tip is fixedly connected to the bottom of the needle. This dispensing curing device allows the adhesive residue at the bottom of the needle tip after dispensing to be scraped off by a cleaning brush on top of the ultraviolet lamp, so that the next dispensing will not be affected by the adhesive residue at the bottom of the needle tip.

[0004] Based on the above technical features, the problem is that after the existing dispensing and curing device dispenses the glue, the residual glue at the bottom of the dispensing needle is scraped off by a cleaning brush. During this process, residual glue will stick to the outer wall at the bottom of the needle along the scraping direction, resulting in poor scraping effect.

[0005] Therefore, it is necessary to solve the above problems by using dispensing and curing equipment suitable for computer keyboard panels. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figures 1 to 3 The dispensing and curing equipment shown is suitable for computer keyboard panels and includes a dispensing station 1. A support frame 3 is fixedly mounted on the dispensing station 1. The support frame 3 is a U-shaped frame and is upside down onto the dispensing station 1. A movable frame 6 is slidably mounted on the support frame 3. The movable frame 6 is a U-shaped frame and its top is slidably connected to the top of the support frame 3.

[0020] A motor 4 is fixedly mounted on the side of the support frame 3, and a horizontal lead screw 5 is placed inside the support frame 3. The lead screw 5 is rotatably connected to the two sides of the support frame 3, and the output shaft of the motor 4 is coaxially and fixedly connected to the lead screw 5. The lead screw 5 passes through the movable frame 6 and is threadedly connected to the movable frame 6. The top of the movable frame 6 is in a limiting sliding fit with the top of the support frame 3.

[0021] A glue storage tank 9 is fixedly installed inside the movable frame 6, and an air pump 8 is fixedly installed on the glue storage tank 9. The glue outlet of the air pump 8 is fixedly connected to a glue delivery tube 10, and the glue delivery tube 10 is fixedly connected to a needle tube 11. A vertically oriented first cylinder 7 is fixedly installed inside the movable frame 6, and a vertically oriented needle tube 11 is fixedly mounted on the telescopic shaft of the first cylinder 7. A vertically downward glue scraping hole is opened at the bottom of the movable frame 6, and the needle tip of the needle tube 11 faces the glue scraping hole and slides in cooperation with the glue scraping hole.

[0022] A collection box 15 is installed at the bottom of the mobile frame 6. The top of the collection box 15 is open and slidably connected to the mobile frame 6. A horizontal second cylinder 12 is fixedly installed at the bottom of the mobile frame 6, and the telescopic shaft of the second cylinder 12 is fixedly connected to the collection box 15.

[0023] An inclined scraper 17 is fixedly installed inside the collection box 15, with the top of the scraper 17 tilted towards the wiping roller 18. The top of the scraper 17 slides in contact with the bottom of the movable frame 6.

[0024] The scraper 17 divides the inside of the collection box 15 into an adhesive storage chamber 20 and a liquid storage chamber 19, with the liquid storage chamber 19 filled with alcohol. A horizontal wiping roller 18 is placed inside the liquid storage chamber 19 and is rotatably connected to the collection box 15. The wiping roller 18 rolls in contact with the bottom of the moving frame 6, while the bottom of the wiping roller 18 is immersed in the alcohol.

[0025] The wiping roller 18 and the collection box 15 are driven by a linkage mechanism, which includes a first gear 14, a second gear 21, and a rack 13. Both the first gear 14 and the second gear 21 are rotatably mounted on the outer wall of the collection box 15, and are meshed together. The rack 13 is fixed to the bottom of the movable frame 6, and the second gear 21 meshes with the rack 13.

[0026] The bottom of the movable frame 6 is fixed with an ultraviolet lamp 16 for adhesive curing.

[0027] A conveyor belt 2 for transporting a computer keyboard panel is installed on the side of the dispensing station 1.

[0028] Working principle: When dispensing glue onto the computer keyboard panel on the dispensing station 1, the first cylinder 7 is activated. The telescopic shaft of the first cylinder 7 extends downward and drives the needle tube 11 downward. The needle at the bottom of the needle tube 11 passes through the glue scraping hole and gradually moves towards the glue dispensing position on the computer keyboard panel.

[0029] Once the needle reaches the dispensing position, the air pump 8 is activated. The air pump 8 draws glue from the glue reservoir 9 and delivers it into the syringe 11 through the glue delivery tube 10. In this example, the glue delivery tube 10 is a flexible tube. The glue in the syringe 11 is then applied to the dispensing position via the bottom needle.

[0030] After the dispensing is completed, the telescopic shaft of the first cylinder 7 retracts, and the needle tube 11 moves upward. When the bottom of the needle tube 11 is flush with the bottom plane of the moving frame 6, the first cylinder 7 is turned off and the second cylinder 12 is started. The telescopic shaft of the second cylinder 12 extends and pushes the collection box 15 to move. In this embodiment, the top of the collection box 15 is provided with a clearance hole to allow space for the glue scraping hole, so as to prevent the collection box 15 from scraping off the glue.

[0031] As the collection box 15 moves, it moves the scraper 17. When the scraper 17 passes through the scraping hole, it scrapes off the adhesive residue on the needle tip at the bottom of the syringe 11. The scraped-off adhesive flows into the adhesive storage chamber 20 through the scraper 17. During the scraping process, some stubborn adhesive will adhere to the moving frame 6 and the bottom of the needle tip.

[0032] As the collection box 15 moves, the wiping roller 18 follows behind the scraper 17. When the wiping roller 18 rolls over the area scraped by the scraper 17, it applies alcohol to the bottom of the moving frame 6, dissolving the stubborn adhesive. Because the movement of the collection box 15 drives the second gear 21, the rack 13 pushes the second gear 21 to rotate. The second gear 21 then drives the first gear 14 to rotate, which in turn drives the wiping roller 18 to rotate. At this point, the rotation direction of the wiping roller 18 is not aligned with its travel direction, resulting in relative sliding between the wiping roller 18 and the bottom of the moving frame 6. The wiping roller 18 then removes the dissolved stubborn adhesive, improving the scraping effect.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
