[0002] After coating the front of the unit board of the display screen, it can play a good role in waterproofing and moisture-proofing. If the installation environment is in a coastal city or an area in the south with more rain, the coating can play a good protective role, reduce the possibility of short circuits, and increase the service life of the screen.
[0003] Currently, relevant laminating equipment is generally used, but the laminating efficiency of the relevant laminating equipment is low, and the position of the protective film needs to be adjusted many times. The protective film is not attached accurately enough. After the protective film is attached, individual bubbles will remain on the display screen. The quality of the attachment is not good enough, and manual quality inspection is required one by one to find and remove the bubbles. Summary of the invention

The placement rack is equipped with a rolling mechanism, and the rolling mechanism is used to stick the protective film tightly to the display screen. The placement rack is equipped with a lifting mechanism, and the lifting mechanism is used to support the protective film.
[0006] As a further preferred scheme, the feeding mechanism includes an electric winding roller, a guide roller, a release paper roll and a protective film. An electric winding roller is provided on the side of the box body away from the placement rack. The electric winding roller is located at the cover. A guide roller is rotatably installed on the side of the box body close to the placement rack. Several protective films are evenly spaced on the release paper roll.

[0007] As a further preferred scheme, the rolling mechanism includes a secondary guide rail, a secondary electric slider, a connecting frame and a rolling roller. Two secondary guide rails are installed on one side of the placement frame, and secondary electric sliders are installed on both secondary guide rails. A connecting frame is installed on both secondary electric sliders. A rolling roller is rotatably installed between the two connecting frames, and the rolling roller is hollow.
[0008] As a further preferred embodiment, the rolling roller is located above the placement frame.
[0009] As a further preferred scheme, the material pushing mechanism includes a transverse axis, a material receiving plate, a transverse spring and a trapezoidal plate. Two transverse axes are slidably installed on the side of the placement frame close to the rolling roller. The two transverse axes are symmetrically arranged. A material receiving plate is installed at the end of the two transverse axes close to each other. The upper parts of the two material receiving plates are inwardly convex. A transverse spring is connected between the material receiving plate and the placement frame. The transverse spring is wound on the transverse axis.

[0010] As a further preferred embodiment, a driving mechanism is also included, and the driving mechanism is arranged on the box body, the connecting frame and the rolling roller. The driving mechanism is used to drive the rolling roller to rotate. The driving mechanism includes column gear 1, column gear 2 and a rack. A column gear 1 is installed at both ends of the rolling roller, and a column gear 2 is installed on each of the two connecting frames. The column gear 1 on the same side is meshed with the column gear 2 on the same side. A rack is installed between the two sides of the placement frame and the inner two sides of the box body, and the racks on both sides are meshed with the column gear 2 on both sides.
[0011] As a further preferred solution, the diameter of the second column gear is greater than the diameter of the first column gear.
[0012] As a further preferred embodiment, a pressing mechanism is also included, which is arranged on the rolling roller and the box body.

Two concave-convex plates are installed on both sides of the box body, and the outer ends of the two piston rods are in contact with the two concave-convex plates.
[0013] The present invention has the following advantages: 1. Through the intermittent winding of the electric winding roller, a part of the protective film can be intermittently separated from the release paper, and the inner convex parts on the upper parts of the two receiving plates and the rolling roller contact one side of the protective film, so as to fix the protective film, and then control the main electric slider to drive the placement frame to drive the display screen to continue to move, and the display screen drives the protective film to continue to move, and the other part of the protective film will be completely separated from the release paper, and then the two auxiliary electric sliders drive the rolling roller to push the protective film to the display screen, which can make the protective film fit to the display screen more accurately, and also improve the coating efficiency of the display screen.
[0014] 2. Through the meshing of the rack and the column gear 2, the column gear 2 can be driven to rotate, and the column gear 2 drives the column gear 1 and the rolling roller to rotate. When the protective film is attached to the display screen, the rolling roller can squeeze out the bubbles between the protective film and the display screen, thereby reducing the bubbles on the display screen after the protective film is attached, thereby improving the quality of the display screen coating.
[0015] 3. Through the guiding effect of the concave-convex plate, the piston rods on both sides will continuously move back and forth under the action of the return spring. The reciprocating movement of the piston rods on both sides can compress the gas in the middle of the rolling roller. The gas compression in the middle of the rolling roller can expand several rubber skins. When the protective film is attached to the display screen, the expansion of the rubber skin can continuously press the protective film, thereby further reducing the bubbles on the display screen after the protective film is attached, and further improving the quality of the display screen coating.

A connecting frame 93 is installed on the two secondary electric sliders 92. A rolling roller 94 is rotatably installed between the two connecting frames 93, and the rolling roller 94 is hollow.
[0032] The laminating roller 94 is located above the placement rack 7.
[0033] The material pushing mechanism includes a transverse axis 1011, a material receiving plate 101, a transverse spring 102 and a trapezoidal plate 103. Two transverse axes 1011 are slidably installed on the side of the placement frame 7 close to the rolling roller 94. The two transverse axes 1011 can rotate along the placement frame 7 and slide along the placement frame 7. The two transverse axes 1011 are symmetrically arranged. A material receiving plate 101 is installed at one end of the two transverse axes 1011 close to each other. The upper parts of the two material receiving plates 101 are convex.

Two placement grooves 104 are opened on the side of the placement frame 7 close to the rolling roller 94, and the two transverse axes 1011 and the material receiving plate 101 are located in the two placement grooves 104.
[0034] When laminating the display screen, the operator first starts the electric winding roller 81 to wind up the release paper roll 83. After the release paper roll 83 drives the protective film 84 thereon to move to the guide roller 82, a part of the protective film 84 on the release paper roll 83 will be separated from the release paper roll 83, and another part of the protective film 84 on the release paper roll 83 will also be in contact with the release paper roll 83, and the protective film 84 can be vertically suspended in the box body 2. Then the operator turns off the electric winding roller 81, and the operator places a display screen in the placement groove 104 on the placement rack 7 through the discharge port 4. Then the operator controls the main electric slider 6 to move to one side on the main guide rail 5, and the main electric slider 6 drives the display screen placed obliquely on the placement rack 7 to move. After one side of the display screen moves to contact with one side of the protective film 84, the inner convex parts on the upper parts of the two receiving plates 101 are After the two auxiliary electric sliders 92 are in contact with one side of the protective film 84, the operator controls the main electric slider 6 to stop, and then the operator starts the two auxiliary electric sliders 92 to move to one side along the two auxiliary guide rails 91, and the two auxiliary electric sliders 92 drive the two connecting frames 93 and the rolling rollers 94 to move to one side. After the rolling rollers 94 contact one side of the protective film 84, the operator controls the auxiliary electric slider 92 to stop, and contacts one side of the protective film 84 through the inner convex parts of the upper parts of the two receiving plates 101 and the rolling rollers 94, so as to fix the protective film 84, and then controls the main electric slider 6 to drive the placement frame 7 to drive the display screen to continue to move, and the display screen drives the protective film 84 to continue to move, and the other part of the protective film 84 will be completely separated from the release roll 83. After the placement frame 7 drives the display screen to move to a suitable position, the operator controls the main electric slider 6 to stop;The operator controls the auxiliary electric slider 92 to continue to drive the rolling roller 94 to move, and the rolling roller 94 drives the protective film 84 to slowly move toward the direction of the display screen for bonding. The protective film 84 pushes the horizontal axis 1011 and the receiving plate 101 to move toward the display screen, and the horizontal spring 102 twists accordingly. The two connecting frames 93 drive the trapezoidal plate 103 to move to one side, and the two receiving plates 101 are just located in the placement groove 104. At this time, the protective film 84 and the display screen are bonded to a half state. Initially, the horizontal spring 102 is in a stretched state, and the receiving plates 101 on both sides are in a vertical state. In the vertical state, the two trapezoidal plates 103 move to be separated from the two horizontal shafts 1011, and under the action of the horizontal spring 102, the horizontal shafts 1011 on both sides and the material receiving plate 101 move away from each other, and the material receiving plates 101 on both sides are separated from the protective film 84. Under the action of the horizontal spring 102, the material receiving plates 101 on both sides will swing back to the vertical state, and the two auxiliary electric sliders 92 continue to drive the rolling rollers 94 to push the protective film 84 to stick to the display screen. After the protective film 84 on the display screen is attached, the operator controls the auxiliary electric slider 92, the connecting frame 93 and the rolling rollers 94 moves and resets, the connecting frame 93 drives the two trapezoidal plates 103 to move and reset, and after the two trapezoidal plates 103 contact the two transverse shafts 1011, the two transverse shafts 1011 drive the two receiving plates 101 to move in a direction close to each other, and the two transverse springs 102 are stretched accordingly.

[0035] Embodiment 2: Based on embodiment 1, Figure 8-Figure 10 As shown, a driving mechanism is also included, and the driving mechanism is arranged on the box body 2, the connecting frame 93 and the rolling roller 94. The driving mechanism is used to drive the rolling roller 94 to rotate. The driving mechanism includes a column gear 111, a column gear 112 and a rack 113. A column gear 111 is installed at both ends of the rolling roller 94, and a column gear 112 is installed on each of the two connecting frames 93. The column gear 111 on the same side is meshed with the column gear 2 112 on the same side. A rack 113 is installed between the two sides of the placement frame 7 and the inner two sides of the box body 2, respectively, and the racks 113 on both sides are meshed with the column gear 2 112 on both sides.
[0036] The diameter of the second column gear 112 is greater than the diameter of the first column gear 111 .
[0037] When the connecting frame 93 and the rolling roller 94 move, they drive the column gear 111 and the column gear 2 112 to move. The movement of the column gear 2 112 will mesh with the rack 113. Under the action of the rack 113, the column gear 2 112 will rotate. The rotation of the column gear 2 112 will drive the column gear 111 to rotate. The rotation of the column gear 111 can drive the rolling roller 94 to rotate. Since the diameter of the column gear 2 112 is larger than the diameter of the column gear 111, the column gear 111 will not mesh with the rack 113. The meshing of the rack 113 and the column gear 2 112 can drive the column gear 2 112 to rotate. The column gear 2 112 drives the column gear 111 and the rolling roller 94 to rotate. When the protective film 84 is attached to the display screen, the rolling roller 94 can squeeze out the bubbles between the protective film 84 and the display screen, thereby reducing the bubbles on the display screen after the protective film 84 is attached, thereby improving the quality of the display screen coating.
[0038] Embodiment 3: Based on embodiment 2, Figure 5-Figure 11 As shown, a pressing mechanism is also included, which is arranged on the laminating roller 94 and the box body 2. The pressing mechanism is used to press the protective film 84 when the display screen is attached to the protective film 84. Piston rods 121 are slidably installed on both sides of the laminating roller 94. Reset springs 122 are connected between the two piston rods 121 and the two sides of the laminating roller 94. Four rubber skins 123 are evenly spaced and embedded on the laminating roller 94. Two concave-convex plates 124 are installed on both sides of the box body 2, and the outer ends of the two piston rods 121 are in contact with the two concave-convex plates 124.
[0039] During the movement of the rolling roller 94, the piston rod 121, the return spring 122 and the rubber skin 123 will be driven to move. The piston rod 121 will move along the concave-convex plate 124. Under the guidance of the concave-convex plate 124, the piston rods 121 on both sides will continuously reciprocate under the action of the return spring 122. The reciprocating movement of the piston rods 121 on both sides can compress the gas in the middle of the rolling roller 94. The gas compression in the middle of the rolling roller 94 can expand the four rubber skins 123. When the protective film 84 is attached to the display screen, the expanded rubber skin 123 can continuously press the protective film 84, thereby further reducing the bubbles on the display screen after the protective film 84 is attached, and further improving the quality of the display screen coating.
