Detailed implementation mode

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following describes the implementation modes of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] As Figures 1-6 shown, this embodiment provides a screen film laminating device, including a positioning part 10 and a film laminating part 20. The positioning part 10 is used to position the screen 1, and the film laminating part 20 is used to laminate a protective film on the top surface of the positioned screen 1.

[0027] Specifically, as Figure 1 shown, the positioning part 10 includes an operating table 11, a boss 12, pressing parts 13 respectively arranged on both sides of the operating table 11, and a lifting part 14. The boss 12 is arranged at the front end of the operating table 11 and is used to limit one end of the screen 1. The pressing parts 13 are respectively arranged on both sides of the operating table 11, and the lifting part 14 is installed below the bottom surface of the operating table 11.

[0028] The film laminating part 20 includes a film laminating assembly 21 and a film roll 22. The film laminating assembly 21 is mounted on the top of the operating table 11 and is movably arranged along the length direction of the operating table 11. The film roll 22 is arranged at one end of the operating table 11 away from the boss 12.

[0029] During use, place the screen 1 to be laminated on the top surface of the operating table 11, and make one end of the screen 1 abut against the boss 12. Start the lifting part 14 to move the lifting part 14 downward and pull the lower end of the pressing part 13 downward, so that the other end of the pressing part 13 moves toward both sides of the screen 1, thereby limiting both sides of the screen 1. Start the film laminating assembly 21 to pull out the end of the film roll 22 and move along the length direction of the operating table 11, thereby realizing automatic film lamination of the screen 1.

[0030] Specifically, as Figures 2-3As shown in the figure, the pressing member 13 includes an L-shaped plate 131, a pressing block 132, a support 133, a screw 134, and a rubber pad 135. The support 133 is vertically installed on the ground. The connection between the horizontal part and the vertical part of the L-shaped plate 131 is rotatably connected to the upper end of the support 133. The horizontal part of the L-shaped plate 131 is located below the operating table 11 and extends towards the center of the operating table 11, so as to ensure that the horizontal part of the L-shaped plate 131 is located at the upper end of the lifting member 14.

[0031] The screw 134 is vertically connected to the upper end of the vertical part of the L-shaped plate 131 and extends towards the operating table 11. The pressing block 132 is arranged at one end of the screw 134 facing the operating table 11. When limiting screens 1 with different widths, it can be satisfied by adjusting the length of the screw 134 extending out of the vertical part of the L-shaped plate 131, so as to increase the usage range. The rubber pad 135 is arranged on the side of the pressing block 132 facing the operating table 11, so as to prevent the side wall of the screen 1 from being damaged or scratched during clamping.

[0032] Shrinkage rods 111 are respectively vertically arranged on the bottom surface of the operating table 11. A first spring 112 is sleeved outside the shrinkage rods 111. The lower ends of the shrinkage rods 111 are correspondingly arranged opposite to the top surface of the horizontal part of the L-shaped plate 131.

[0033] The lifting member 14 includes a cylinder 141 and a top plate 142. The cylinder 141 is vertically installed on the ground, and its output end is vertically upward. The top plate 142 is horizontally installed at the output end of the cylinder 141, and both ends of the top plate 142 are respectively arranged opposite to the lower part of the corresponding horizontal part of the L-shaped plate 131.

[0034] During use, start the cylinder 141 to make the cylinder 141 push the top plate 142 to move vertically upward, so that both ends of the top plate 142 respectively push the corresponding horizontal parts of the L-shaped plate 131 upward. At this time, the shrinkage rods 111 shrink, and the first spring 112 is compressed. The L-shaped plate 131 rotates outward along its connection with the support 133, so that the vertical part of the L-shaped plate 131 drives the pressing block 132 to turn away from the operating table 11 to the side far from the operating table 11. Then, place the screen 1 to be laminated on the operating table 11. The cylinder 141 retracts downward, so as to drive the top plate 142 to move vertically downward to release the upward thrust on the horizontal part of the L-shaped plate 131. At this time, under the action of the restoring force of the first spring 112, the shrinkage rods 111 extend downward, so as to push the horizontal part of the L-shaped plate 131 to rotate downward to the horizontal state, so that the vertical part of the L-shaped plate 131 drives the pressing block 132 to move towards the direction where the operating table 11 is located, so as to realize the limitation of both sides of the screen 1, and the operation is simple.

[0035] Specifically, as Figure 1 、 Figure 6 shown, a set of conveying rollers 113 is arranged at the other end of the operating table 11 for conveying the protective film towards the direction where the operating table 11 is located.

[0036] Specifically, as Figure 1 , Figures 4-5 shown, the film laminating assembly 21 includes a telescopic rod movably arranged along the length direction of the operating table 11, and the telescopic rod is arranged vertically. The upper end of the telescopic rod is connected to the frame. A pulling member 211 is arranged at the lower end of the telescopic rod. The pulling member 211 can be in the form of a suction cup to conveniently suck the end of the protective film extending out of a set of conveying rollers 113. A cross bar 216 is arranged on the side of the pulling member 211 facing the film roll 22. The upper end of the cross bar 216 is connected to the telescopic rod, and vertical rods 214 are respectively arranged vertically downward at both ends of the cross bar 216. A second spring 215 is sleeved on the vertical rod 214. The lower end of the vertical rod 214 is sleeved with a connecting seat 213. The upper end of the second spring 215 abuts against the cross bar 216, and the lower end abuts against the upper end of the connecting seat 213. Both ends of the roller 212 are rotatably connected to the connecting seat 213, and a sponge pad is covered on the outer wall of the roller 212 to buffer the contact stress between the roller 212 and the screen 1, thereby effectively protecting the screen 1; and it is ensured that the vertical distance from the lowest point of the roller 212 to the top surface of the operating table 11 is less than the vertical distance from the lower end of the pulling member 211 to the top surface of the operating table 11. A hot melt knife 217 is arranged on the side of the roller 212 facing the film roll 22, and the projection of the hot melt knife 217 on the operating table 11 falls between a set of conveying rollers 113 and the roller 212. The upper end of the hot melt knife 217 is connected to the frame.

[0037] During use, the pulling member 211 sucks one end of the protective film, and then moves along the frame to one end of the convex platform 12 of the operating table 11, so that the screen 1 is covered by the protective film. At this time, the telescopic rod moves downward, so that the roller 212 presses the protective film against the screen 1. Then, the telescopic rod enters the return stroke, so that the roller 212 pastes the protective film on the top surface of the screen 1 along the top surface of the screen 1. Finally, the hot melt knife 217 is started to move downward to cut off the protective film. After cutting off, the hot melt knife 217 is retracted upward. When using next time, a set of conveying rollers 113 is started. After the protective film extends out of a set of conveying rollers 113 by a predetermined length, the telescopic rod is started to move downward, and the extending end of the protective film is sucked up again. Then, the screen 1 to be laminated is placed on the operating table 11, and the clamping process is repeated, and the next screen 1 can be laminated.

[0038] The above are only the preferred embodiments of the present invention, and do not represent that they are the only ones or limit the present invention. Those skilled in the art should understand that without departing from the scope of the present invention, various changes or equivalent replacements made to the present invention all fall within the scope of protection of the present invention.
