Description

Technical Field

[0001] The invention relates to the technical field of instrument panel film application, in particular to an instrument panel film application device with an anti-bubble function. Background Art

[0002] The electric vehicle instrument panel is a device that reflects the working status of various vehicle systems. Common indicators on the instrument panel include turn indicators, battery indicator lights, light indicators, speed display lights, and warning lights. During the production of electric vehicle instrument panels, it is usually necessary to apply a protective film on the instrument panel to protect the surface of the instrument panel and prevent it from being scratched and damaged. Existing instrument panel protective films are usually applied manually. The manual application mode requires the operator to master certain skills and experience. In addition, the manual application operation is relatively cumbersome, which makes the application time longer and seriously affects the efficiency of instrument panel film application. At the same time, during the application process, it is difficult to ensure that the position of the manual film is consistent, which affects the quality of the instrument panel film application. Summary of the Invention

[0003] The object of the present invention is to provide an instrument panel film-sticking device with an anti-bubble function to solve the problems raised in the prior art.

[0004] To achieve the above object, the present invention provides the following technical solutions: A device for applying film to an instrument panel with an anti-bubble function comprises a body, a fixing plate symmetrically provided on the top of the body, a sliding groove provided on opposite sides of two fixing plates, a rotating screw provided in the sliding groove, a film applying assembly provided on the rotating screw, the film applying assembly being slidably connected to the rotating screw, a fixing platform provided in the body, the fixing platform being used to place the instrument panel, and output slots provided around the fixing platform; The staff placed the instrument panel on a fixed table and placed the film on the film assembly. By rotating the screw, the screw drives the film assembly to move back and forth along the sliding groove. During the reciprocating movement, the film assembly not only cleans the surface of the instrument panel, but also transports and transfers the film so that the film is transported to the surface of the instrument panel. Atomized water is also sprayed on the instrument panel and the side of the film close to the instrument panel, thereby improving the fit between the film and the instrument panel, and thus improving the film quality of the instrument panel. After the film covers the surface of the instrument panel, the film and the instrument panel are squeezed to discharge excess water and air between the film and the instrument panel, thereby achieving the effect of eliminating bubbles.

[0005] Preferably, a driving motor is provided inside the sliding groove, a driving shaft of the driving motor is connected to a rotating screw, and thread grooves are symmetrically provided on the rotating screw; The controller controls the drive motor to start, and the drive shaft of the drive motor drives the rotating screw to rotate. During the rotation process, the rotating screw drives the nut to move, and the nut then moves along the sliding groove. Since the rotating screw is symmetrically provided with thread grooves, the rotating screw does not need to change the rotation direction to drive the nut to reciprocate, and then drives the rotating shaft to reciprocate along the surface of the instrument panel.

[0006] Preferably, the film sticking assembly includes two nuts, which are connected to the rotating screw, and support frames are provided on opposite sides of the two nuts. The two support frames are directly provided with rotating shafts, and the rotating shafts are rotatably connected to the support frames.

[0007] When the staff places the instrument panel on the fixed table and fixes it, and then places the membrane on the placement rack, the controller controls the micro motor to start, and the drive shaft of the micro motor drives the membrane to move. The membrane moves from the placement rack to the extension rack, and then moves to the top of the rotating shaft through the extension rack and contacts the surface of the rotating shaft. At this time, the rotating shaft rotates under the action of the rotating motor; At the same time, the rotating screw drives the nut to move, and the movement of the nut drives the support frame to move, and the support frame drives the rotating shaft to move. When the support frame moves toward the placement frame, the rotating shaft rotates toward the side close to the protrusion, and the rotating shaft contacts the lower surface of the membrane during the rotation, so that the rotating shaft drives the membrane to move, and the membrane then moves toward the side close to the protrusion.

[0008] Preferably, an extension frame is provided on the side of the support frame away from the rotating axis, a placement frame is provided on the side of the extension frame away from the support frame, a roller is provided on the placement frame, a micro motor is provided on the placement frame, a driving shaft of the micro motor is connected to the roller, and the roller is rotatably connected to the placement frame.

[0009] When the support frame drives the rotating shaft to reset, the rotating shaft contacts the surface of the instrument panel during movement, and the expanded airbag plate squeezes the surface of the instrument panel to drain and exhaust water. The rotating shaft is affected by the movement of the support frame, so that the rotating shaft rotates and squeezes against the surface of the instrument panel, and the excess atomized water and air between the instrument panel and the membrane are discharged. The discharged atomized water flows to the output slot and is finally discharged through the output slot.

[0010] Preferably, a rotating motor is provided on one side of one of the support frames away from the rotating shaft, and a driving shaft of the rotating motor is connected to the rotating shaft; a sliding sleeve is provided on the other side of the support frames away from the rotating shaft, and the sliding sleeve is rotatably connected to the rotating shaft.

[0011] Preferably, a delivery pipe is provided in the rotating shaft, a connecting pipe is provided in the sliding sleeve, one end of the connecting pipe is connected to the delivery pipe, and the other end of the connecting pipe is connected to the water pump through a pipeline, a plurality of airbag plates are provided on the surface of the rotating shaft, and the plurality of airbag plates are staggered along the axis of the rotating shaft, an air delivery groove is provided on the side of the rotating shaft away from the delivery pipe, and the air delivery groove is connected to the airbag plate, an air delivery pipe is also provided on the sliding sleeve, one end of the air delivery pipe is connected to the air delivery groove, and the other end of the air delivery pipe is connected to the air pump; a plurality of atomization ports are provided between two adjacent airbag plates, and the atomization ports are connected to the delivery pipe.

[0012] Preferably, the rotation direction of the rotation shaft is opposite to the movement direction of the support frame.

[0013] When the rotating shaft rotates, the airbag plate is in a contracted state, and several atomization ports are exposed on the surface of the rotating shaft. Then the water pump delivers the external water source to the connecting pipe in the sliding sleeve through the pipeline. The external water source is then delivered to the delivery pipe through the connecting pipe, and then delivered to the atomization port by the delivery pipe, and finally sprayed to the lower surface of the instrument panel and the membrane through the atomization port. After the atomized water is sprayed out from the atomization port on the side of the rotating shaft away from the bump, it will act as a cleaning agent and cooperate with the airbag plate under the rotation of the rotating shaft to complete the cleaning and wiping operation of the instrument panel surface, thereby making the instrument panel surface smooth and improving the adhesion of the membrane to the instrument panel surface; and the atomized water sprayed from the atomization port on the side of the rotating shaft close to the bump will act between the instrument panel and the membrane, thereby using water to expel the air between the instrument panel and the membrane, and avoid air remaining between the running-in instrument panel and generating bubbles; When the nut moves to the side of the sliding groove away from the body, the membrane is completely separated from the protrusion and attached to the surface of the instrument panel. Then the nut continues to reset under the action of the rotating screw. At this time, the rotating shaft is separated from the surface of the instrument panel, and the rotating motor stops rotating. Then, in the process of resetting the nut, the nut drives the support frame to reset, and the support frame drives the rotating shaft to reset. In the process of resetting the rotating shaft, the vacuum pump transports the external gas through the pipeline to the air pipe in the sliding sleeve, and transports the external gas to the air groove through the air pipe, and finally transports it to the airbag plate, so that the airbag plate is affected by the air pressure and expands, and then several airbag plates cover and wrap several atomization ports during the expansion process.

[0014] Preferably, a protrusion is provided on the side of the support frame away from the placement frame, and the protrusion is located on the side of the support frame away from the fixing plate, and the protrusion is used to limit the contact state between the membrane and the surface of the instrument panel.

[0015] Under the action of the rotating shaft, the membrane moves from the rotating shaft to the side close to the bump. When the membrane moves to the surface of the bump, the two sides of the membrane are restricted by the bump, and the center position of the membrane is sprayed with atomized water. Under the action of gravity, the membrane will present a concave state with a low middle and high sides, so that the central area of ​​the membrane first contacts the surface of the instrument panel, and then as the membrane detaches from the bump, the membrane gradually covers the surface of the instrument panel from the center to the two side edges. During the covering process, the air between the membrane and the instrument panel will also be transported from the center to the two side edges under the action of atomized water, further achieving the effect of eliminating bubbles.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The rotating screw drives the film sticking assembly to move back and forth along the sliding groove, so that in the process of reciprocating movement, the film sticking assembly not only cleans the surface of the instrument panel, but also transports and transfers the film so that the film is transported to the surface of the instrument panel, and sprays atomized water on the instrument panel and the side of the film close to the instrument panel, thereby improving the fitting quality of the film and the instrument panel, and further improving the film sticking quality of the instrument panel; and after the film covers the surface of the instrument panel, the film and the instrument panel are squeezed to discharge excess water and air between the film and the instrument panel, thereby achieving the effect of eliminating bubbles.

[0017] 2. The membrane moves from the rotating shaft to the side close to the bump under the action of the rotating shaft. When the membrane moves to the surface of the bump, the two sides of the membrane are restricted by the bump, and the center position of the membrane is sprayed by the atomized water. Under the action of gravity, the membrane will present a concave state with the middle lower and the two sides higher, so that the central area of ​​the membrane first contacts the surface of the instrument panel, and then as the membrane detaches from the bump, the membrane gradually covers the surface of the instrument panel from the center to the two side edges. During the covering process, the air between the membrane and the instrument panel will also be transported from the center to the two side edges under the action of the atomized water, further achieving the effect of eliminating bubbles.

[0018] 3. Since the thread grooves are symmetrically arranged on the rotating screw, the rotating screw does not need to change the rotation direction to drive the nut to reciprocate, and then drive the rotating shaft to reciprocate along the surface of the instrument panel.

[0028] As a specific embodiment of the present invention, a protrusion 30 is provided on the side of the support frame 22 away from the placement frame 25. The protrusion 30 is located on the side of the support frame 22 away from the fixing plate 11. The protrusion 30 is used to limit the contact state between the membrane and the instrument panel surface.

[0029] Working principle of the present invention: When the staff places the instrument panel on the fixed table 14 and fixes it, and then places the film on the placement rack 25, the controller controls the micro motor to start, and the drive shaft of the micro motor drives the film to move. The film moves from the placement rack 25 to the extension rack 24, and then moves to the top of the rotating shaft 23 through the extension rack 24 and contacts the surface of the rotating shaft 23. At this time, the rotating shaft 23 rotates under the action of the rotating motor; At the same time, the screw rod 13 is rotated to move the nut 21, and the movement of the nut 21 drives the support frame 22 to move, and the support frame 22 drives the rotating shaft 23 to move. When the support frame 22 moves toward the placement frame 25, the rotating shaft 23 rotates toward the side close to the protrusion 30. During the rotation, the rotating shaft 23 contacts the lower surface of the film, so that the rotating shaft 23 drives the film to move, and the film then moves toward the side close to the protrusion 30. When the rotating shaft 23 rotates, the airbag plate 28 is in a contracted state, and a plurality of atomizing ports 29 are exposed on the surface of the rotating shaft 23. Then, the water pump delivers the external water source through the pipeline to the connecting pipe in the sliding sleeve 26. The external water source is then delivered to the delivery pipe 27 through the connecting pipe, and then delivered to the atomizing port 29 by the delivery pipe 27, and finally sprayed toward the lower surface of the instrument panel and the membrane through the atomizing port 29. After the atomized water is sprayed out from the atomizing port 29 on the side of the rotating shaft 23 away from the protrusion 30, it will act as a cleaning agent. Under the action of the rotation of the rotating shaft 23, it cooperates with the airbag plate 28 to complete the cleaning and wiping operation of the instrument panel surface, thereby making the instrument panel surface smooth and improving the adhesion of the membrane to the instrument panel surface; and the atomized water sprayed out from the atomizing port 29 on the side of the rotating shaft 23 close to the protrusion 30 will act between the instrument panel and the membrane, thereby using water to expel the air between the instrument panel and the membrane, and avoid air remaining between the instrument panel and the membrane and generating bubbles. Under the action of the rotating shaft 23, the membrane moves from the rotating shaft 23 to the side close to the protrusion 30. When the membrane moves to the surface of the protrusion 30, the two sides of the membrane are restricted by the protrusion 30. The center of the membrane is sprayed with atomized water, and under the action of gravity, the membrane will present a concave state with a lower center and higher sides. As a result, the center area of ​​the membrane first contacts the surface of the instrument panel, and then as the membrane detaches from the protrusion 30, the membrane gradually covers the surface of the instrument panel from the center to the two side edges. In the process of covering, the air between the membrane and the instrument panel is also transported from the center to the two side edges under the action of the atomized water, further achieving the effect of eliminating bubbles. When the nut 21 moves to the side of the sliding groove 12 away from the body 1, the membrane is completely separated from the protrusion 30 and attached to the surface of the instrument panel. Then the nut 21 continues to reset under the action of the rotating screw 13. At this time, the rotating shaft 23 is separated from the surface of the instrument panel, and the rotating motor stops rotating. Then, during the process of resetting the nut 21, the nut 21 drives the support frame 22 to reset, and the support frame 22 drives the rotating shaft 23 to reset. During the process of resetting the rotating shaft 23, the vacuum pump transports the external gas through the pipeline to the air pipe in the sliding sleeve 26, and transports the external gas to the air tank through the air pipe, and finally transports it to the airbag plate 28, so that the airbag plate 28 is affected by the air pressure and expands, and then several airbag plates 28 cover and wrap several atomization ports 29 during the expansion process; When the support frame 22 drives the rotating shaft 23 to return to its original position, the rotating shaft 23 contacts the surface of the instrument panel during the movement, and the inflated airbag plate 28 squeezes the surface of the instrument panel to drain and exhaust air. The rotating shaft 23 is affected by the movement of the support frame 22, so that the rotating shaft 23 rotates and squeezes against the surface of the instrument panel, and the excess atomized water and air between the instrument panel and the membrane are discharged. The discharged atomized water flows toward the output slot 15 and is finally discharged through the output slot 15. When the nut 21 moves to the initial position, that is, the rotating shaft 23 is disengaged from the instrument panel surface again, the staff removes the instrument panel with the film applied from the fixing table 14 and places the next instrument panel to be applied with the film on the surface of the fixing table 14.
