[0037] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0038] Such as Figures 1 to 3As shown in the figure, an aluminum single - panel surface lamination and film - covering device includes a conveying rack 1 and a film - covering rack 2 fixed on the conveying rack 1. A cutting part 4 is provided on the conveying rack 1. The cutting part 4 includes a support frame horizontally arranged on the conveying rack 1. A lead screw is rotatably arranged inside the support frame. A nut seat is threadedly installed on the lead screw. A cutting knife is fixedly arranged at the bottom of the nut seat. A driving motor is fixedly arranged on the support frame. The output end of the driving motor is fixedly connected to one end of the lead screw, so as to timely cut off the protective film after the film - covering of an aluminum single - panel is completed. The aluminum single - panel surface lamination and film - covering device further includes:

[0039] A film - covering part 3 arranged on the film - covering rack 2.

[0040] The film - covering part 3 and the cutting part 4 are sequentially distributed on the conveying rack 1 along the conveying direction of the aluminum single - panel.

[0041] The film - covering part 3 includes:

[0042] A support frame 31 fixed on the film - covering rack 2. A film - covering groove 35 is provided on the support frame 31.

[0043] A film - covering member 32 arranged in the film - covering groove 35 for film - covering the surface of the aluminum single - panel.

[0044] A dust - blowing member 33 arranged on the support frame 31 for dust - removing the surface of the aluminum single - panel.

[0045] A three - way valve pipe 34 arranged between the dust - blowing member 33 and the film - covering member 32.

[0046] The dust - blowing member 33 and the film - covering member 32 are sequentially distributed on the support frame 31 along the conveying direction of the aluminum single - panel.

[0047] During the conveying process of the aluminum single - panel, it will sequentially pass through the bottom of the dust - blowing member 33 and the film - covering member 32, realizing synchronous dust - removing and film - covering. There is no need to complete each step before proceeding to the next step, enabling the dust - removing, film - covering, and protective - film cutting steps of the aluminum single - panel to form a pipeline - type operation, greatly improving the film - covering effect of the aluminum single - panel.

[0048] In this embodiment, the aluminum single - panel surface lamination and film - covering device further includes two trapezoidal auxiliary conveyors 6 oppositely arranged on the conveying rack 1, and the conveying surfaces of the two auxiliary conveyors 6 are perpendicular to the film - covering surface of the aluminum single - panel. The auxiliary conveyors 6 and the film - covering part 3 are sequentially distributed on the conveying rack 1 along the conveying direction of the aluminum single - panel.

[0049] By relatively arranging the inclined conveying surfaces of the two trapezoidal auxiliary conveyors 6, when the aluminum single board passes between the two auxiliary conveyors 6, the friction force between the conveying surface of the auxiliary conveyor 6 and the aluminum single board is utilized to correct the position of the aluminum single board so that it is on the center line between the two, and when a part of the aluminum single board disengages from between the two auxiliary conveyors 6, dust removal and film covering can be carried out on its surface, achieving the effect of synchronously performing three operation steps, greatly improving the film covering accuracy of the aluminum single board and the efficiency of the film covering process.

[0050] In this embodiment, the film covering member 32 includes:

[0051] A hollow roller 321 slidably sleeved with a vertical groove provided on the inner wall of the support frame 31. The end of the hollow roller 321 can also rotate in the vertical groove, and a plurality of through holes 322 are provided on the hollow roller 321.

[0052] Connecting arms 323 oppositely arranged at both ends of the hollow roller 321.

[0053] A feeding roller 325 slidably connected with a guiding groove provided on the support frame 31. The end of the feeding roller 325 passes through the guiding groove, and the end of the feeding roller 325 is rotatably connected with a shaft groove 324 provided at one end of the connecting arm 323.

[0054] A limiting block 326 inserted into the shaft groove 324 for limiting the end of the feeding roller 325.

[0055] When film covering the surface of the aluminum single board, after a part of the aluminum single board disengages from between the two auxiliary conveyors 6, it will directly enter below the dust blowing member 33. After the dust removal operation of the dust blowing member 33, it immediately contacts the protective film attached to the surface of the hollow roller. Since the surface of the protective film in contact with the aluminum single board has a certain adhesiveness, after the two come into contact, the protective film will adhere to the dust-removed surface of the aluminum single board, and with the continuous movement of the aluminum single board, the overall film covering operation of the surface of the aluminum single board is completed. During this process, under the pulling force of the movement of the aluminum single board, the feeding roller 325 rotates and the feeding speed of the protective film is synchronized with the movement speed of the aluminum single board, making the film covering operation of the aluminum single board efficient and accurate, and avoiding the problem of position deviation in the film covering on the surface of the aluminum single board.

[0056] In this embodiment, the dust blowing member 33 includes:

[0057] An air pump 331 fixed to the support frame 31.

[0058] A blowing nozzle 332 obliquely fixed to the support frame 31.

[0059] A blowing pipe 333 provided between the air outlet of the air pump 331 and the air inlet of the blowing nozzle 332.

[0060] The air outlet of the air blowing nozzle 332 is inclined downward and faces the opposite direction of the aluminum single board transportation, which not only does not affect the subsequent film covering operation, but also can complete the dust removal operation on the surface of the aluminum single board, and can also realize the two steps simultaneously, improving the efficiency of the aluminum single board film covering process.

[0061] In this embodiment, two ends of the three-way valve pipe 34 are respectively communicated with the air inlet of the air pump 331 and one end of the hollow roller 321, and the remaining end is directly communicated with the processing environment, so as to switch the air inlet path of the air pump 331 before and after the protective film is cut. For example, when the protective film is covered, the path of the three-way valve pipe 34 is switched to directly communicate the air pump 331 with the working environment, and high-speed air flow is delivered to the air blowing nozzle 332 to realize the dust removal operation on the surface of the aluminum single board. When the covering and cutting of one aluminum single board are completed, the path of the three-way valve pipe 34 is switched to extract air from the hollow roller 321, so as to form negative pressure suction at the through hole 322. The negative pressure suction between the cut opening of the protective film and the through hole 322 adsorbs and fixes the protective film on the hollow roller 321, avoiding the problems of folding or fluttering during the alternation of covering two aluminum single boards, which affects the covering effect of the latter aluminum single board and improves the accuracy of continuous covering of aluminum single boards.

[0062] In this embodiment, the hollow roller 321 is located obliquely below the loading roller 325, and the loading roller 325 is located between the hollow roller 321 and the air blowing nozzle 332. With such a design, the hollow roller 321 can have a certain vertical displacement margin in the vertical direction to cover aluminum single boards with different thicknesses. Through the combined use of the connecting arm, the guiding groove, and the vertical groove, the loading roller 325 can synchronously move up and down when the thickness of the aluminum single board changes, reducing the influence of the change in the thickness of the aluminum single board on the covering effect.

[0063] In this embodiment, the aluminum single board surface lamination device further includes:

[0064] The main conveyor 5 provided in the conveying frame 1, the cutting part 4 straddles both sides of the main conveyor 5, and the hollow roller 321 is located between the loading roller 325 and the cutting part 4, so as to be able to cut the protective film in time after the covering is completed, improving the efficiency of the aluminum single board film covering process.

[0065] The PLC controller 7 provided on the conveying frame 1 for electronically controlling and switching the air flow channel of the three-way valve pipe 34, and the PLC controller 7 is electrically connected to the main conveyor 5, the cutting part 4, and the air pump 331 respectively.

[0066] When the PLC controller 7 laminates the protective film, it switches the air intake path of the three-way valve pipe 34 to directly connect the air pump 331 with the working environment, and conveys high-speed air flow to the blowing nozzle 332 to achieve the surface dust removal operation of the aluminum single board. When the lamination and cutting of one aluminum single board are completed, it switches the air intake path of the three-way valve pipe 34 to connect the air pump 331 with the inside of the hollow roller 321, so as to form a negative pressure suction at the through hole 322. The negative pressure suction between the cut edge of the protective film and the through hole 322 adsorbs and fixes the protective film on the hollow roller 321, avoiding the problems of folding or fluttering during the alternation of the lamination of two aluminum single boards, which may affect the lamination effect of the latter aluminum single board, improving the accuracy of continuous lamination of aluminum single boards. And after the lamination of the aluminum single board is completed, the PLC controller 7 can control the main conveyor 5 to stop, so as to facilitate the cutting department 4 to cut the protective film.

[0067] The above are only the preferred embodiments of the present invention, and the parts not described in the present invention can be implemented by adopting or referring to the existing technologies. Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. The changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the present invention should also belong to the protection scope of the present invention.
