[0026] The impurity removal component 2 includes a fixed block 21 arranged on the inner wall of the housing 1, a connecting plate 22 is fixedly arranged on the front of the fixed block 21, a flapping plate 23 is rotatably arranged on the bottom of the left side of the connecting plate 22, and an electric telescopic rod 24 is vertically arranged on the top of the inner wall of the housing 1, the output end of the bottom of the electric telescopic rod 24 passes through the top of the fixed block 21 and extends to the bottom thereof, and the telescopic end of the bottom of the electric telescopic rod 24 is rotatably connected to the back of the flapping plate 23;

[0027] The extension of the output end of the electric telescopic rod 24 drives the beating plate 23 to rotate along the rotation point between it and the connecting plate 22, thereby beating the aluminum-plated film passing therethrough, so that the dust and impurities on the side of the aluminum-plated film that needs to be coated fall below.

[0028] The adhesion component 3 includes a film roll 31 rotatably arranged on the left side of the shell 1, a group of guide rollers 32 are longitudinally rotatably arranged on the inner side of the shell 1, a group of transmission rods 33 are longitudinally rotatably arranged at the bottom of the inner wall of the shell 1, and a conveyor belt 34 is arranged on the peripheral side of the transmission rod 33.

[0029] A winding device for the bonded aluminized film and substrate can be provided on the right side of the shell 1, that is, at the exit where bonding is completed. By setting the guide roller 32, the aluminized film can be guided from the film roll 31 to the bottom of the beating plate 23, and the substrate can be conveyed by the conveyor belt 34.

[0030] The impurity removal component 2 also includes a cleaning brush 25 which is longitudinally rotatable and arranged inside the shell 1. The cleaning brush 25 is located above the conveyor belt 34. The rear end of the cleaning brush 25 passes through the inner wall of the shell 1 and extends to the back thereof. The rear end of the cleaning brush 25 is connected to the rear end belt of the left transmission rod 33.

[0031] When the transmission rod 33 rotates, the cleaning brush 25 is driven to rotate, so that the cleaning brush 25 cleans the bonding surface of the substrate while cleaning the dropped objects from above to prevent affecting the subsequent bonding, and the dust removal effect is good.

[0032] A rubber cylinder 35 is longitudinally rotatably disposed inside the housing 1 and to the right of the cleaning brush 25 . A rubber box 36 is disposed on the front of the housing 1 , and the bottom end of the rubber box 36 is communicated with the front of the rubber cylinder 35 .

[0033] The bottom of the glue box 36 is also provided with an electric control valve. After a period of time, the electric control valve opens, and the glue inside the glue box 36 falls into the glue cylinder 35 at the bottom. The glue cylinder 35 is connected to the glue box 36, and the glue box 36 will not rotate when the glue cylinder 35 rotates.

[0034] A glue coating roller 37 is longitudinally rotatably arranged inside the housing 1 and tightly fitted to the right side of the rubber cylinder 35 .

The rear end of the glue coating roller 37 is connected to the rear end belt of the cleaning brush 25 .

[0035] The cleaning brush 25 is driven to rotate by the rotation of the transmission rod 33, and then the glue coating roller 37 is driven to rotate. When the glue coating roller 37 rotates, the bottom of its peripheral side surface will fit against the surface of the rubber cylinder 35 and drive the rubber cylinder 35 to rotate accordingly, and then the glue on the surface of the rubber cylinder 35 is evenly coated on the glue coating roller 37, and then the glue coating roller 37 coats the glue on the lower surface of the aluminum-plated film lifted by it.

[0036] A sliding box 38 is provided on the right side inside the outer shell 1 so as to slide up and down, and a pressure roller 39 is provided on the inner side of the sliding box 38 so as to rotate longitudinally. A driving motor 4 for driving the transmission rod 33 to rotate is provided at the bottom of the front side of the outer shell 1, and the output end on the back side of the driving motor 4 is fixedly connected to the front end of the left transmission rod 33.

[0037] By setting the sliding box 38, the pressure roller 39 can be moved downward to the maximum extent, thereby pressing down the aluminized film passing under the pressure roller 39, so that the glue-coated surface of the aluminized film is closely fitted with the transmission substrate to complete the adhesion of the aluminized film.

[0038] A fixing plate 5 is arranged on the right side inside the shell 1 and above the sliding box 38, a sliding rod 6 is arranged at the bottom of the fixing plate 5, the peripheral side surface of the sliding rod 6 is slidably connected to the inner side of the sliding box 38, and a pressing spring 7 is arranged on the peripheral side surface of the sliding rod 6 and at the top of the sliding box 38.

[0039] By arranging the sliding rod 6 and the pressing spring 7, the aluminum-plated film can be pressed downward without generating a large force to damage the aluminum-plated film.

[0040] The working principle of a bonding device for producing PET aluminized film provided by the utility model is as follows:

[0041] Step 1: When in use, the aluminized film is pulled out from the film roll 31 and passes through two guide rollers 32, then pulled over the glue coating roller 37, and finally passes under the pressure roller 39, and the substrate to be bonded is placed on the conveyor belt 34;

[0042] Step 2: The output end of the driving motor 4 drives the cleaning brush 25 and the glue roller 37 to rotate, thereby driving the aluminum-plated film to move to the right side of the housing 1. At the same time, the output end of the electric telescopic rod 24 extends to drive the slapping plate 23 to rotate along the rotation point between it and the connecting plate 22, thereby slapping the aluminum-plated film passing therethrough, so that the dust and impurities on the side of the aluminum-plated film to be coated fall below. While the cleaning brush 25 cleans the bonding surface of the substrate, it also cleans the fallen objects slapped from the top to prevent affecting the subsequent bonding, and the dust removal effect is good;

[0043] Step 3: When the aluminum-plated film passes over the glue coating roller 37, the bottom of the peripheral side of the glue coating roller 37 will fit against the surface of the rubber cylinder 35 when the glue coating roller 37 rotates, and the rubber cylinder 35 is driven to rotate accordingly, so that the glue on the surface of the rubber cylinder 35 is evenly coated on the glue coating roller 37, and then the glue coating roller 37 coats the glue on the lower surface of the aluminum-plated film lifted by it. When the aluminum-plated film passes under the pressure roller 39, the sliding rod 6 and the pressing spring 7 are set to make the pressure roller 39 slide downward, so that the glue-coated surface of the aluminum-plated film is closely fitted with the transmission substrate to complete the adhesion of the aluminum-plated film.

[0044] Compared with the related art, the bonding device for producing PET aluminized film provided by the utility model has the following advantages:

[0045] Beneficial effects:

[0046] The rotation of the output end of the driving motor 4 drives the cleaning brush 25 and the glue coating roller 37 to rotate, thereby driving the aluminum-plated film to move to the right side of the shell 1. At the same time, the output end of the electric telescopic rod 24 extends to drive the flapping plate 23 to rotate along the rotation point between it and the connecting plate 22, thereby flapping the aluminum-plated film passing therethrough, so that dust and impurities on the side of the aluminum-plated film that needs to be coated fall below. While the cleaning brush 25 cleans the bonding surface of the substrate, it also cleans the dropped objects flapped from the top. The structure is simple and practical, and to a large extent avoids the problem of bubbles or impurities appearing on the aluminum-plated film during adhesion.

[0047] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
