Description

Technical Field

[0001] This application relates to the field of automatic film replacement technology, and specifically discloses an automatic film replacement device for automobile front bumpers. Background Technology

[0002] Car film is a type of film that is attached to the exterior surface of a car. It can be used to change the original color of the car and protect the paint from minor scratches. It is a product that can both showcase the owner's personality and protect the paint.

[0003] Regarding car window tinting, the current process involves thoroughly washing the entire car, manually measuring the film size, and then applying the film. This method is simple, but it cannot guarantee the quality of the tinting in certain details.

[0004] First, we know that apart from the front and rear bumpers being made of plastic, the rest of the car body is made of metal. Therefore, in most vehicles on the market, the front and rear bumpers are connected to the car body by snap-fit ​​and thread. So, there must be a seam between the front and rear bumpers and the car body. This seam is very small. When applying the film, after the whole film is applied, a knife is used to cut the film at this seam before resealing it. This operation is not inherently problematic.

[0005] However, as the car is used, the sealing points are located very far out and there is a risk of them falling off. Furthermore, after cutting the car film at this joint with a knife, the front and rear bumpers have a wall thickness, meaning that the wall thickness is not covered by the car film, resulting in a flaw in the film application. Although the flaw is not obvious, owners of high-end and luxury cars often cannot accept flaws in the film application. Therefore, in order to ensure the quality of the film application, we suggest removing the front and rear bumpers before applying the film.

[0006] Finally, for some vehicles that have had their film reapplied, manually removing the film is also quite troublesome. Therefore, the inventor proposes an automatic film replacement device for the front bumper of a car. Summary of the Invention

[0007] The purpose of this invention is to solve the problems of incomplete application of film to the front bumper and the inconvenience of film replacement in traditional car window tinting methods.

[0008] To achieve the above objectives, the present invention provides the following basic solution:

[0009] An automatic film changing device for a car front bumper includes a worktable, a fixing frame disposed on the worktable for fixing the front bumper, and a film changing assembly movable relative to the front bumper.

[0010] The film changing assembly includes a self-rotating conversion cylinder, a hot mold removal assembly, a heat treatment cleaning assembly, an extrusion drying assembly, and an extrusion film application assembly arranged around the conversion cylinder. The hot mold removal assembly, heat treatment cleaning assembly, extrusion drying assembly, and extrusion film application assembly can be switched as the conversion cylinder rotates.

[0011] The workbench is also equipped with an alignment component for aligning the hot molding assembly and the heat treatment scratch removal assembly with the front bumper.

[0012] The principle and effect of this basic scheme are as follows:

[0013] 1. Compared with existing technologies, this device has a simple structure and ingenious design. It is equipped with a hot mold removal component, a heat treatment cleaning component, an extrusion drying component, and an extrusion film application component to realize the entire process of mold removal, cleaning, and film application. Furthermore, the hot mold removal component, the heat treatment cleaning component, the extrusion drying component, and the extrusion film application component can be switched with the rotation of the conversion cylinder, thereby solving the problems of incomplete film application and troublesome film replacement in traditional automotive film application methods.

[0014] 2. Compared with existing technologies, the heat extraction component and the heat treatment cleaning component achieve continuous heat utilization. The heat from the heat extraction is fed back to the heat treatment cleaning component, resulting in a better heat treatment cleaning effect and effectively removing dirt from the front bumper.

[0015] 3. Compared with existing technologies, the whole device has a stronger overall integrity and is mainly effective on the film of the front bumper. It can apply the film more comprehensively. The method of removing the front and rear bumpers and then applying the film has more steps, but the overall quality is higher. Moreover, the film can cover the upper and lower wall thickness of the front bumper very well. Compared with the whole film application, it is of higher quality and reduces film defects.

[0016] Furthermore, a through groove is provided on one side of the worktable of the fixed frame, and sliding grooves are provided on the inner walls of both sides of the through groove. Sliding blocks are rotatably connected to both ends of the conversion cylinder, and the sliding blocks are slidably connected to the sliding grooves.

[0017] Furthermore, a first cylinder is symmetrically arranged on the workbench away from the fixed frame. The extended end of the first cylinder is connected to a connecting column, and the free end of the connecting column is connected to a sliding block to push the rotating cylinder to move horizontally.

[0018] Furthermore, the heat extraction mold assembly includes a first frame connected to the rotating cylinder, an electric heating wire disposed on the surface of the first frame, and a blower disposed inside the electric heating wire. The electric heating wire has hollowed-out sections on both sides, and a negative pressure fan and a negative pressure air duct are provided in the hollowed-out sections. The free end of the negative pressure air duct passes through the conversion cylinder and is placed in the water inside the rotating cylinder.

[0019] Furthermore, the heat treatment cleaning assembly includes a second frame, a plurality of nozzles disposed within the second frame, water pipes connected to the nozzles, and a water pump. The water pipes are inserted into the water inside the conversion cylinder, and a water pump switch is provided on the surface of the second frame.

[0020] Furthermore, the squeeze drying assembly includes a third frame and a plurality of folded absorbent cotton disposed within the third frame, wherein the folded absorbent cotton intersects and the intersection point is located at the center point of the third frame.

[0021] Furthermore, the folded absorbent cotton is made of elastic material. When the folded absorbent cotton is folded up and down, it generates elasticity after being subjected to force, thereby expanding the absorbent area of ​​the folded absorbent cotton.

[0022] Furthermore, the extrusion film assembly includes a fourth frame and a second cylinder disposed within the fourth frame. The extended end of the second cylinder is connected to an upper film frame, which is a concave upper film frame. Both the upper and lower ends of the upper film frame can cover the wall thickness of the front bumper.

[0023] Furthermore, the alignment assembly includes a mounting block fixed to one side near the front bumper and a horizontal block rotatably connected to the mounting block. The horizontal block can contact the bottom of the heat-molding assembly and the heat treatment cleaning assembly to ensure that the heat-molding assembly and the heat treatment cleaning assembly remain in the same straight line with the front bumper.

[0032] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0033] The reference numerals in the accompanying drawings include: platform 1, support column 2, fixing frame 3, front bumper 4, first cylinder 5, conversion cylinder 6, push block 7, mounting block 8, horizontal block 9, hot molding assembly 10, first frame 1001, blower 1002, electric heating wire 1003, negative pressure air duct 1004, negative pressure fan 1005, heat treatment cleaning assembly 11, extrusion drying assembly 12, second frame 1201, center point 1202, folded absorbent cotton 1203, extrusion film assembly 13, fourth frame 1301, second cylinder 1302, film frame 1303, water pump switch 14, nozzle 15, sliding block 16, connecting column 17, thermoplastic 18.

[0034] Implementation, for example Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown:

[0035] An automatic film changing device for a car front bumper includes a worktable, a fixing frame 3 disposed on the worktable for fixing the front bumper 4, and a film changing assembly movable relative to the front bumper 4.

[0036] Regarding the workbench, such as Figure 1 As shown, the workbench includes a table plate 1 and support columns 2 fixed to the bottom of the table plate 1. The support columns 2 are made of stainless steel and are evenly distributed around the bottom of the table plate 1.

[0037] like Figure 3 As shown, a fixing frame 3 is symmetrically fixed on the right side of the workbench. A thermoplastic 18 is placed on the fixing frame 3. The front bumper 4 is manually removed. After the thermoplastic 18 is heated, the bottom of the front bumper 4 is glued to the thermoplastic 18 to fix the position of the front bumper 4.

[0038] The membrane changing assembly includes a self-rotating and horizontally movable conversion cylinder 6, a hot mold removal assembly 10 for membrane treatment, a heat treatment cleaning assembly 11, an extrusion drying assembly 12, and an extrusion film loading assembly 13 arranged around the conversion cylinder 6. The hot mold removal assembly 10, the heat treatment cleaning assembly 11, the extrusion drying assembly 12, and the extrusion film loading assembly 13 can be switched as the conversion cylinder 6 rotates.

[0039] Regarding the rotation of the rotating cylinder: A through groove is provided on the worktable on the left side of the fixed frame 3, and sliding grooves are provided on the inner walls of both sides of the through groove. Sliding blocks 16 are rotatably connected to both ends of the conversion cylinder 6, and the sliding blocks 16 are slidably connected to the sliding grooves. The rotation of the rotating cylinder is achieved through the sliding blocks 16; for example... Figure 1 As shown, a pusher block 7 is provided on the outer periphery of the rotating cylinder. The pusher block 7 is used to realize the rotation of the rotating cylinder and change the positional relationship of the subsequent functional components.

[0040] Regarding the horizontal movement of the rotating cylinder: A first cylinder 5 is symmetrically arranged on the upper left side of the workbench away from the fixed frame 3. The extended end of the first cylinder 5 is connected to a connecting column 17. The free end of the connecting column 17 is connected to the sliding block 16 to push the rotating cylinder to move horizontally. The rotating cylinder moves closer to the front bumper 4 through the first cylinder 5.

[0041] The worktable is also equipped with an alignment component for aligning the hot molding assembly 10 and the heat treatment scratch removal assembly 11 with the front bumper 4.

[0042] The alignment assembly includes a mounting block 8 fixed to the left side of the front bumper 4 and a horizontal block 9 rotatably connected to the mounting block 8. The horizontal block 9 can contact the bottom of the heat extraction assembly 10 and the heat treatment cleaning assembly 11 to ensure that the heat extraction assembly 10 and the heat treatment cleaning assembly 11 are kept in the same straight line as the front bumper 4.

[0043] Specifically: Since the hot molding assembly 10 and the heat treatment cleaning assembly 11 do not need to be very close to the front bumper 4, a horizontal block 9 is used to better realize the functions of the hot molding assembly 10 and the heat treatment cleaning assembly 11. When the hot molding assembly 10 is rotated above the horizontal block 9 and blocked by the horizontal block 9, it means that the hot molding assembly 10 is aligned with the front bumper 4. Similarly, when it is necessary to switch to the heat treatment cleaning assembly 11, the horizontal block 9 is rotated to rotate the heat treatment cleaning assembly 11 above the horizontal block 9. When it is blocked by the horizontal block 9, it means that the heat treatment cleaning assembly 11 is aligned with the front bumper 4.

[0044] like Figure 2As shown, the hot mold assembly 10 includes a first frame 1001 connected to the rotating cylinder, an electric heating wire 1003 disposed on the surface of the first frame 1001, and a blower 1002 disposed inside the electric heating wire 1003. The electric heating wire 1003 has hollowed-out sections on both sides, and a negative pressure fan 1005 and a negative pressure air duct 1004 are provided in the hollowed-out sections. The free end of the negative pressure air duct 1004 passes through the conversion cylinder 6 and is placed in the water inside the rotating cylinder.

[0045] This step is for removing the film. The old film is removed, and hot air is generated using the electric heating wire 1003 and the blower 1002 to soften the film. Usually, the edges of the film will curl up after softening. At this time, the negative pressure fan 1005 is started, and the negative pressure air duct 1004 is used to accelerate the curling of the film. After a certain period of time, it can be quickly peeled off manually. The negative pressure air duct 1004 will draw the hot air around the film into the conversion cylinder 6.

[0046] like Figure 3 As shown, the heat treatment cleaning assembly 11 includes a second frame 1201, a plurality of nozzles 15 disposed within the second frame 1201, and water pipes and a water pump connected to the nozzles 15. The water pipes are inserted into the water inside the converter cylinder 6. A water pump switch 14 is provided on the surface of the second frame 1201, which controls the opening of the water pump. This step removes the residual adhesive on the bumper and can effectively clean the dirt on the front bumper 4 because the water in the converter cylinder 6 is heated and the water from the nozzles 15 is hot water, which can accelerate the removal of adhesive.

[0047] like Figure 5 As shown, the squeeze-drying assembly 12 includes a third frame and several folded absorbent cotton 1203 disposed within the third frame. The folded absorbent cotton 1203 intersect, and the intersection point is located at the center point 1202 of the third frame. This is a pre-treatment for membrane replacement, i.e., drying of moisture. The movement of the squeeze-drying assembly 12 is achieved by the first cylinder 5. The alignment assembly is no longer working. The front bumper 4 is fully placed and squeezed against the third frame. The front bumper 4 will go all the way to the center point 1202 of the third frame, causing the folds of the folded absorbent cotton 1203 to unfold, exposing a larger and more absorbent area. Under the action of squeezing, the front bumper 4 is squeezed and dried, making the surface of the front bumper 4 smooth.

[0048] like Figure 7As shown, the extrusion film assembly 13 includes a fourth frame 1301 and a second cylinder 1302 disposed within the fourth frame 1301. The extended end of the second cylinder 1302 is connected to an upper film holder 1303. The upper film holder 1303 is concave. Both the upper and lower ends of the upper film holder 1303 can cover the wall thickness of the front bumper 4. The second cylinder 1302 completes the extrusion action, manually covering the upper film holder 1303 with a new film. The new film needs to cover the upper and lower concave points of the upper film holder 1303. The second cylinder 1302 pushes the upper film holder 1303 toward the front bumper 4. Under extrusion, the new film covers the front bumper 4. Since the upper film holder 1303 is concave, the new film will cover the wall thickness of the front bumper 4, achieving flawless film application.

[0049] Finally, remove the front bumper 4, manually level the new mold located on the front bumper 4, and then use scissors to trim off the excess film edges to complete the film replacement for the front bumper 4.

[0050] This device solves the problems of incomplete film application and troublesome film replacement associated with traditional car window tinting methods.
