This device boasts high efficiency in film peeling and automated film supply, significantly improving application efficiency and production capacity. It is highly practical. However, after applying the film to the dashboard, air bubbles are prone to appear. These bubbles, after being cleaned by the roller, tend to form smaller bubbles, resulting in residual bubbles on the dashboard surface after film application, which affects the aesthetics. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electric bicycle instrument panel coating device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an electric bicycle instrument panel coating device, including a frame, a conveyor on the top of the frame, a mold box fixed to the outer circumference of the conveyor by bolts, an instrument panel placed inside the mold box, a mounting bracket fixed to the top of the frame by bolts, a first dispensing pipe fixed to the inner wall of the top of the mounting bracket by bolts, an upper spray head fixed to the bottom of the first dispensing pipe by threads, a second dispensing pipe fixed to the top of the frame by bolts, a lower spray head fixed to the top of the second dispensing pipe by threads, and both the first and second dispensing pipes connected to an external water pump via flexible hoses, multiple vertically distributed protective films on the top of the frame, a feeding assembly that moves the protective films to the instrument panel on the top of the frame, and a defoaming assembly that squeezes the coated instrument panel on the top of the frame.

[0006] As a further embodiment of this utility model, the feeding assembly includes a linear motor fixed to the top of the frame, a connecting frame fixed to the top of the linear motor by bolts, a first electric push rod fixed to the top of the connecting frame by bolts, a movable plate fixed to the movable end of the first electric push rod by bolts, and a suction cup fixedly installed at the bottom of the movable plate.

[0007] As a further embodiment of this utility model, the defoaming component includes a fixed frame fixed to the top of the frame body. A second electric push rod is fixed to the top outer wall of the fixed frame by bolts. A limit frame is fixed to the movable end of the second electric push rod by bolts. A guide groove is provided at the bottom of the limit frame. Two scrapers are slidably connected in the guide groove. A power component is provided on one side of the limit frame to drive the two scrapers to move in opposite directions.

[0008] As a further embodiment of this utility model, the power assembly includes a servo motor fixed to one side of the limit frame. The output shaft of the servo motor passes through the limit frame and is fixed to a bidirectional lead screw via a coupling. The bidirectional lead screw is threadedly connected to two scrapers respectively.

[0009] As a further embodiment of this invention, the contact surfaces of the two scrapers with the instrument panel have arc-shaped edges.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-4 This utility model provides an electric bicycle instrument panel coating device, including a frame 1, a conveyor 2 on the top of the frame 1, the conveyor 2 being a chain conveyor, a mold box 3 fixed to the outer circumference of the conveyor 2 by bolts, an instrument panel placed inside the mold box 3, an mounting frame 5 fixed to the top of the frame 1 by bolts, a first liquid distribution pipe fixed to the inner wall of the top of the mounting frame 5 by bolts, an upper spray head 4 fixed to the bottom of the first liquid distribution pipe by threads, a second liquid distribution pipe fixed to the top of the frame 1 by bolts, a lower spray head 8 fixed to the top of the second liquid distribution pipe by threads, and both the first and second liquid distribution pipes being connected to an external water pump through hoses, a plurality of vertically distributed protective films 9 on the top of the frame 1, a feeding component that moves the protective films 9 to the instrument panel on the top of the frame 1, and a defoaming component that squeezes the instrument panel after coating on the film on the top of the frame 1;

[0023] In use, the instrument panel is placed inside the mold box 3. The conveyor 2 is started intermittently, and the protective membrane 9 is moved and loaded via the feeding component. The external water pump is started, which delivers the mixture of cleaning fluid and water to the first and second distribution pipes, and sprays it out from the upper nozzle 4 and the lower nozzle 8. The liquid sprayed from the lower nozzle 8 falls onto the protective membrane 9, and the liquid sprayed from the upper nozzle 4 falls onto the instrument panel, so that both are mixed with the liquid. Then, the protective membrane 9 is attached to the instrument panel, and the feeding component is disengaged from the protective membrane 9 and reset. During the contact between the protective membrane 9 and the instrument panel, the conveyor 2 stops running. During the stop of the conveyor 2, the defoaming component squeezes the protective membrane 9 to remove air bubbles between the protective membrane 9 and the instrument panel. Because there is liquid between the protective membrane 9 and the instrument panel, the air bubbles are easier to move and remove, making the removal of air bubbles between the protective membrane 9 and the instrument panel more thorough and improving the coating quality of the device.

[0024] The feeding assembly includes a linear motor 6 fixed to the top of the frame 1. A connecting frame 11 is fixed to the top of the linear motor 6 by bolts. A first electric push rod 12 is fixed to the top of the connecting frame 11 by bolts. A movable plate 13 is fixed to the movable end of the first electric push rod 12 by bolts. A suction cup 14 is fixedly installed at the bottom of the movable plate 13.

[0025] Start the first electric push rod 12 to make the moving plate 13 move up and down reciprocally. Use the suction cup 14 to adsorb the uppermost protective film 9. At the same time, the suction cup 14 shakes up and down and uses inertia to separate the film surface to prevent the multiple layers of protective film 9 from overlapping and being wasted. Start the linear motor 6, which drives the connecting frame 11 to move, thereby realizing the feeding of the protective film 9 and improving the convenience of feeding the device.

[0026] The defoaming component includes a fixed frame 7 fixed to the top of the frame 1. The top outer wall of the fixed frame 7 is fixed with a second electric push rod 15 by bolts. The movable end of the second electric push rod 15 is fixed with a limit frame 16 by bolts. The bottom of the limit frame 16 is provided with a guide groove 18. Two scrapers 19 are slidably connected in the guide groove 18. The contact surfaces of the two scrapers 19 and the protective film 9 have arc-shaped edges, which can reduce the stress when the scrapers 19 come into contact with the protective film 9 and prevent the protective film 9 from being torn. A power component is provided on one side of the limit frame 16 to drive the two scrapers 19 to move in opposite directions.

[0027] The second electric push rod 15 is activated, which drives the limit frame 16 to move, so that the two scrapers 19 come into contact with the protective film 9 (which can be monitored by a visual sensor). The power component drives the two scrapers 19 to move outward at the same time, thereby scraping and pressing the protective film 9, thereby squeezing out the mixture between the protective film 9 and the instrument panel. During the extrusion process, air bubbles will be carried out, thereby making the adhesion between the protective film 9 and the instrument panel tighter.

[0028] The power assembly includes a servo motor 20 fixed on one side of the limit frame 16. The output shaft of the servo motor 20 passes through the limit frame 16 and is fixed to a bidirectional lead screw 17 via a coupling. The bidirectional lead screw 17 is threadedly connected to two scrapers 19 respectively.

[0029] Start the servo motor 20, which drives the bidirectional lead screw 17 to rotate. Under the action of the screw, the two scrapers 19 slide in the guide groove 18, causing the two scrapers 19 to move in opposite directions. This can quickly extrude the mixture and improve the film coating efficiency of the device.

[0030] Multiple drainage channels 21 are provided on both sides of the multiple mold boxes 3, and the drainage channels 21 are connected to the holding slots of the mold boxes 3 for holding the instrument panel. The drainage channels 21 will drain the mixture from the holding slots to prevent the mixture from accumulating and damaging the instrument panel.

[0031] The top of the frame 1 is fixed with multiple detachable placement boxes 10 by bolts, and the protective film 9 is placed in the placement box 10, which allows for quick replacement of the placement box 10 and prevents the stacked protective film 9 from tipping over.

[0032] It should be noted that the conveyor 2, mold box 3, upper nozzle 4, linear motor 6, lower nozzle 8, protective film 9, first electric push rod 12, suction cup 14, second electric push rod 15, bidirectional lead screw 17, and servo motor 20 in this utility model are all general standard parts or electrical parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods, and will not be elaborated on here.

[0033] The working principle of this utility model:

[0034] Place the instrument panel inside mold box 3 and start conveyor 2 intermittently;

[0035] Start the first electric push rod 12 to make the moving plate 13 move up and down reciprocally. Use the suction cup 14 to adsorb the uppermost protective film 9. At the same time, the suction cup 14 shakes up and down and uses inertia to separate the film surface. Start the linear motor 6. The linear motor 6 drives the connecting frame 11 to move and attach the protective film 9 to the instrument panel, thereby realizing the feeding of the protective film 9.

[0036] Start the external water pump to deliver the mixture of cleaning solution and water to the first and second distribution pipes, and spray it out from the upper nozzle 4 and the lower nozzle 8.

[0037] During the feeding process of the protective membrane 9, the liquid sprayed from the lower nozzle 8 will fall onto the protective membrane 9; during the movement of the instrument panel, the liquid sprayed from the upper nozzle 4 will fall onto the instrument panel, thus making both have a mixture of liquids.

[0038] During the process of the protective membrane 9 coming into contact with the instrument panel, the conveyor 2 stops running;

[0039] When the conveyor 2 stops running, the second electric push rod 15 drives the limit frame 16 to move, so that the two scrapers 19 come into contact with the protective film 9. The servo motor 20 is started, and the servo motor 20 drives the bidirectional lead screw 17 to rotate. Under the action of the screw, the two scrapers 19 slide in the guide groove 18 and move outward at the same time, thereby scraping and pressing the protective film 9, thereby extruding the mixture between the protective film 9 and the instrument panel. During the extrusion process, air bubbles will be carried out together, thereby making the adhesion between the protective film 9 and the instrument panel tighter.

[0040] Because there is liquid between the protective film 9 and the instrument panel, the air bubbles are easier to move and thus easier to remove, making the removal of air bubbles between the protective film 9 and the instrument panel more thorough and improving the film coating quality of the device.

[0041] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
