The embodiments of this utility model will be described below based on its overall structure.

[0028] Reference Figures 1 to 3In this embodiment of the present invention, an easy-to-tear, residue-free electronic device cleaning film applicator includes: a support frame 1, a conveyor belt 2 disposed on the inner side of the support frame 1, a first drive motor 3 fixedly connected to the inner side of the support frame 1 below the conveyor belt 2, a rotating disk 4 fixedly connected to the rotating shaft of the first drive motor 3, two sets of L-shaped connecting arms 5 rotatably connected below the rotating disk 4, a T-shaped clamping plate 6 rotatably connected above the L-shaped connecting arms 5, multiple sets of guide rollers 7 rotatably connected to the inner side of the T-shaped clamping plate 6, and clamping devices symmetrically fixedly connected to both sides of the support frame 1. The plate limiting frame 8 and the clamping plate limiting frame 8 are adapted to the T-shaped clamping plate 6, so that the T-shaped clamping plate 6 can only move perpendicular to the moving direction of the conveyor belt 2. The support frame 1 is symmetrically rotatably connected to the first electric telescopic rod 9 and the second electric telescopic rod 10 on both sides. The other end of the first electric telescopic rod 9 is rotatably connected to the cleaning film applying mechanism 11. There are two sets of the first electric telescopic rod 9 and the second electric telescopic rod 10, which are symmetrically arranged on both sides of the support frame 1. The cleaning film applying mechanism 11 is rotatably connected to the other end of the two sets of second electric telescopic rods 10 on both sides.

[0029] Using the above solution: Before applying the film, the position of the electronic device on the conveyor belt 2 must be corrected. When the electronic device on the conveyor belt 2 moves to the middle of the two sets of T-shaped clamping plates 6, the first drive motor 3 can be driven. At this time, the L-shaped connecting arm 5 rotates and pulls the T-shaped clamping plate 6 to move along the direction of the clamping plate limit frame 8, clamping and aligning the electronic device for subsequent cleaning and film application steps.

[0030] Reference Figure 1 and Figures 4 to 6The cleaning and film-applying mechanism 11 includes a first support plate 1101, a second support plate 1102 disposed on the side of the first support plate 1101, a plurality of intermediate support columns 1103 fixedly connected between the first support plate 1101 and the second support plate 1102, a fixing block 1104 fixedly connected to the inner side of the first support plate 1101 and the second support plate 1102, rotating arms 1105 rotatably connected to the inner side of the first support plate 1101 and the second support plate 1102 respectively, a support spring 1106 fixedly connected between the rotating arm 1105 and the fixing block 1104, and a downward pressing and applying roller rotatably connected between the two sets of rotating arms 1105. 1107, to maintain the downward pressure and rotatability of the pressing and bonding roller 1107, a horizontal fixing plate 1109 is fixedly connected between the first support plate 1101 and the second support plate 1102. Two sets of third electric telescopic rods 1110 are rotatably connected to the side of the horizontal fixing plate 1109. A film-applying cutter 1111 is rotatably connected to the movable end of the third electric telescopic rod 1110. A first rotating shaft 1112 is fixedly connected to both sides of the film-applying cutter 1111. The two sets of first rotating shafts 1112 are rotatably connected to the inner side of the first support plate 1101 and the second support plate 1102, respectively. The first rotating shaft 1112 is closer to the first support plate 1101. A first gear 1113 is fixedly connected to the side. Two sets of roller fixing plates 1114 are arranged inside the first support plate 1101 and the second support plate 1102. A second rotating shaft 1115 is fixedly connected to the outside of the roller fixing plate 1114. The two sets of second rotating shafts 1115 are rotatably connected to the inside of the first support plate 1101 and the second support plate 1102, respectively. A film-applying tension roller 1116, a clamping roller 1117, and a power roller 1118 are rotatably connected to the inside of the two sets of roller fixing plates 1114. A second gear 1119 is fixedly connected to the inside of one set of roller fixing plates 1114 near the second support plate 1102. The second gear 1119 and... The first gear 1113 meshes with the second drive motor 1120, which is fixedly connected to the outer side of the other set of roller fixing plates 1114. The rotating shaft of the second drive motor 1120 passes through the roller fixing plate 1114 and is fixedly connected to the power roller 1118. The inner side of the first support plate 1101 is fixedly connected to the support screw 1121. The outer side of the support screw 1121 is provided with a matching limit nut 1122. The outer side of the support screw 1121 is fitted with a film-applying roller 1123. A sponge cleaning roller 1124 is fixedly connected between the first support plate 1101 and the second support plate 1102 for necessary cleaning of electronic equipment before applying the film.

[0031] Using the above scheme: When the electronic device is being clamped and aligned, the first electric telescopic rod 9 can be retracted and the second electric telescopic rod 10 can be extended, so that the electronic device in the alignment is lightly pressed by the sponge cleaning roller 1124. After alignment is completed, driven by the conveyor belt 2, the sponge cleaning roller 1124 cleans the dust off the surface of the electronic device. At this time, the electronic device moves under the power roller 1118, and the power roller 1118 presses the film onto the surface of the electronic device. At this time, the second drive motor 1120 assists in applying the film from the clamping roller 1117 and the power roller 1118. When the electronic device is finished applying the film to its surface, the first electric telescopic rod 9 is slightly extended and the second electric telescopic rod 10 is retracted, so that the electronic device passes under the pressure roller 1107 for secondary pressure, further ensuring the adhesion. At the same time, the third electric telescopic rod 1110 extends, driving the film cutter 1111 to rotate and cut the film. At this time, the first gear 1113 drives the second gear 1119 to rotate, thereby driving the roller fixing plate 1114 to rotate and slightly lift the power roller 1118 upward to avoid collision with the film cutter 1111.

[0032] The working principle of this utility model is as follows: First, insert the film-applying roller 1123 into the support screw 1121 and limit it with the limiting nut 1122. At this time, pull out the film applied by the film-applying roller 1123, pass under the film-applying tension roller 1116, pass between the clamping roller 1117 and the power roller 1118, and cut off the contaminated part at the front end.

[0033] When the electronic device is placed on the conveyor belt 2, as the conveyor belt 2 moves, the electronic device gradually moves between the two sets of T-shaped clamping plates 6. At this time, the first drive motor 3 is started, and its rotating shaft drives the rotating disk 4 to rotate. Then, through the L-shaped connecting arm 5, the T-shaped clamping plate 6 is pulled to move along the direction of the clamping plate limiting frame 8, clamping the electronic device and correcting its position to ensure that the electronic device is perpendicular to the moving direction of the conveyor belt 2.

[0034] While the electronic device is clamped and aligned, the first electric telescopic rod 9 is retracted and the second electric telescopic rod 10 is extended, so that the sponge cleaning roller 1124 is gently pressed on the surface of the electronic device. As the conveyor belt 2 continues to move, the sponge cleaning roller 1124 cleans the surface of the electronic device and removes dust and impurities.

[0035] When the electronic device moves under the power roller 1118, the power roller 1118 starts to work, feeding the film out from between the clamping roller 1117 and the power roller 1118 and pressing it onto the surface of the electronic device. The second drive motor 1120 assists in feeding the film out from between the rollers, ensuring that the film is flatly applied to the electronic device.

[0036] After the film is applied, the first electric telescopic rod 9 is slightly extended and the second electric telescopic rod 10 is retracted, allowing the electronic device to pass under the pressure bonding roller 1107. The pressure bonding roller 1107 maintains downward pressure under the action of the support spring 1106, applying secondary pressure to the film to ensure that the film adheres tightly to the surface of the electronic device.

[0037] At the same time, the third electric telescopic rod 1110 extends, driving the film cutting blade 1111 to rotate and cut off the excess film. At this time, the first gear 1113 drives the second gear 1119 to rotate, which in turn drives the roller fixing plate 1114 to rotate, slightly lifting the power roller 1118 to avoid colliding with the film cutting blade 1111.

[0038] After the film is cut, the conveyor belt 2 continues to move, delivering the electronic device with the film applied out of the device, thus completing the entire film application process.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
