[0032] See also Figure 1 The present invention provides a technical solution, comprising a low-profile copper foil 1, a transparent adhesive layer 2, an optical glass 3, and a high-temperature resistant protective film 4 arranged in sequence.

After dispersion is completed, a 5-10 micron filter is used to filter.

[0035] The beneficial effect of the above technical solution is that the adhesion between the low-profile copper foil 1 and the optical glass 3 can be increased by improving the raw material ratio of the transparent adhesive layer 2, making the connection between the low-profile copper foil 1 and the optical glass 3 more secure.

[0045] Preferably, the bonding component 6 includes: a second fixing plate 33, the second fixing plate 33 is fixedly connected to the table top of the workbench 5, one end of the guide slide 34 is fixedly connected to the second fixing plate 33, the other end of the guide slide 34 is fixedly provided with a stop block 2 40, a drive motor 37 is fixedly connected to the second fixing plate 33, and the output shaft of the drive motor 37 is fixedly sleeved with a bevel gear 2 36, the two ends of the threaded rod 2 39 are respectively movably connected to the second fixing plate 33 and the stop block 2 40, the bevel gear 1 35 is fixedly sleeved on the outer wall of the threaded rod 2 39, and the bevel gear 1 35 is meshed with the bevel gear 2 36, the support plate 38 is movably sleeved on the guide slide 34 and the outer wall of the threaded rod 2 39, and the support plate 38 is threadedly connected to the threaded rod 2 39, the rotating bracket body 41 is fixedly connected to the support plate 38, and the rotating bracket body 41 is movably connected to the pressure roller 42 through the connecting bent rod 401, and a torsion spring is sleeved on the connecting shaft of the rotating bracket body 41 and the connecting bent rod 401.

[0046] The working principle and beneficial effects of the above technical solution are as follows: when laminating the display screen, after the low-profile copper foil 1 is moved to the booster assembly 7 by any manipulator, the drive motor 13 is started to drive the drive gear 14 to rotate back and forth, so that the rack 16 drives the fixed plate 15 to drive the U-shaped mounting frame 17 to move back and forth in the front and rear directions. The mutual use of the limiting slide 11 and the limiting slider 12 can prevent the U-shaped mounting frame 17 from shaking and move more smoothly.

[0047] At the same time, the driving motor 21 drives the threaded rod 20 to rotate, so that the threaded sleeve 21 drives the mounting block 22 to move up and down, and after adjusting to a preset height (the height is mainly set based on the thickness of the display screen), the electric telescopic rod 25 lowers the rubber roller 29 to abut against the low-profile copper foil 1, and the linear motor 1 23 drives the electric telescopic rod 25 to move back and forth along the driving cavity 2 24. At this time, the transparent glue in the hose 26 is sprayed onto the low-profile copper foil 1 through the nozzle 28. In summary, the U-shaped mounting frame 17 is driven to move back and forth in the front and back directions by the fixing plate 15, and the rubber roller 29 is driven to move back and forth in the left and right directions by the linear motor 1 23, so that the rubber roller 29 moves on the low-profile copper foil 1 and applies the transparent glue to form a transparent glue layer 2. While the rubber roller 29 moves, the heat pump 18 blows hot air from the hot air outlet 32 ​​through the bellows 30 and the connecting pipe 31 to the transparent glue layer 2 to prevent it from solidifying.

[0048] After the transparent adhesive layer 2 is formed, the optical glass 3 is moved onto the low-profile copper foil 1 by any manipulator, and the bevel gear 2 36 is driven to rotate by starting the drive motor 37. At this time, the bevel gear 1 35 drives the threaded rod 2 39 to rotate, so that the support plate 38 moves downward along the guide slide 34. In this process, the two sets of pressure rollers 42 will first abut against the center of the upper surface of the optical glass 3, and as the support plate 38 continues to move downward, the two sets of pressure rollers 42 move away from each other along the upper surface of the optical glass 3, and after moving to the edge of the optical glass 3, the drive motor 37 is reversed, so that the two sets of pressure rollers 42 are moved away from each other. The two sets of pressing rollers 42 move along the upper surface of the optical glass 3 in a direction approaching each other. In this way, the two sets of pressing rollers 42 repeatedly roll on the upper surface of the optical glass 3, expelling bubbles while making the low-profile copper foil 1 and the optical glass 3 adhere more tightly. Subsequently, the low-profile copper foil 1 and the optical glass 3 that have been connected after solidification are moved out of the booster assembly 7 by any robot and the high-temperature resistant protective film 4 is applied. The torsion spring sleeved on the connecting shaft of the rotating bracket body 41 and the connecting bent rod 401 can further provide a part of the pressure, which not only assists the application, but also enables the pressing roller 42 to be reset.

[0049] The above method can not only realize mass production but also ensure stable bonding force, which not only improves production efficiency but also greatly increases service life.

[0050] Example 3

[0051] Based on any one of Examples 1-2, please refer to Figure 4 and Figure 5 The booster assembly 7 includes: a material placement plate 43 and a hollow platform 44. The hollow platform 44 is installed on the surface of the workbench 5, and the top of the hollow platform 44 is an open structure. The material placement plate 43 is movably arranged in the opening of the hollow platform 44. The inner wall of the hollow platform 44 is provided with a limited chute 2 45. A pressure column 1 49 is fixed with a limited slider 2 48 on one side close to the limited chute 2 45, and the limited slider 2 48 is movably arranged in the limited chute 2 45. A pressure column 1 49 is provided with a plurality of groups of tooth blocks 1 50 on the side away from the limited chute 2 45. The two ends of the connecting spring 1 47 are respectively connected to the pressure plate One 46 is fixedly connected to the pressure column one 49, the top of the pressure column two 55 is fixedly connected to a pressure plate two 53, the two ends of the connecting spring two 56 are respectively fixedly connected to the bottom of the pressure column two 55 and the bottom of the inner wall of the hollow platform 44, a plurality of gear blocks two 54 are provided on the side of the pressure column two 55 close to the pressure column one 49, the fixed column two 51 is fixedly connected to the bottom of the inner wall of the hollow platform 44, and the fixed column two 51 is provided between the pressure column one 49 and the pressure column two 55, the driving gear two 52 is rotatably connected to the fixed column two 51, and the driving gear two 52 is respectively engaged with the gear block one 50 and the gear block two 54.

[0052] Preferably, a limiting slide groove three 57 is provided at the bottom of the inner wall of the hollow platform 44, one end of the first connecting rod 58 is movably extended into the limiting slide groove three 57, the other end of the first connecting rod 58 is hinged to the connecting plate 64, a guide groove 59 is provided on the first connecting rod 58, one end of the second connecting rod 61 is movably connected to the guide groove 59 through a limiting column 60, the other end of the second connecting rod 61 is fixedly connected to the sliding sleeve 62, and the sliding sleeve 62 is movably sleeved on the outer wall of the third connecting rod 63, the two ends of the connecting spring three 65 are respectively fixedly connected to the third connecting rod 63 and the connecting plate 64, the fixed end of the telescopic rod 66 is fixedly connected to the sliding sleeve 62, the movable end of the telescopic rod 66 extends into the fixed sleeve 68, and is fixedly connected to the top of the inner wall of the fixed sleeve 68, the movable end of the telescopic rod 66 is sleeved with a connecting spring four 67, and the top of the fixed sleeve 68 abuts against the bottom of the material placement plate 43.

[0053] The working principle and beneficial effects of the above technical solution are as follows: when the upper surface of the optical glass 3 is repeatedly rolled by the two sets of pressure rollers 42, the material placement plate 43 is pressurized and the telescopic rod 66 is compressed through the fixed sleeve 68, and the third connecting rod 63 and the second connecting rod 61 are given downward pressure through the sliding sleeve 62. At this time, the second connecting rod 61 slides in the guide groove 59 through the limiting column 60, so that the two groups of first connecting rods 58 have a force to slide along the limiting sliding groove 3 57 in the direction of approaching each other, and the third connecting rod 63 gives a pressure to the connecting plate 64 through the connecting spring 3 65, so that the two groups of first connecting rods 58 have a force to slide along the limiting sliding groove 3 57 in the direction of moving away from each other. The two forces cause the two sets of sliding sleeves 62 to slide within a small range on the third connecting rod 63, thereby forming a dynamic balance between the entirety of the sliding sleeve 62 and the material placement plate 43. That is, the two sets of pressing rollers 42 move away from each other along the upper surface of the optical glass 3, and the material placement plate 43 exerts an upward reaction force on the low-profile copper foil 1, so that the optical glass 3 is always in contact with the two sets of pressing rollers 42. After the two sets of pressing rollers 42 move to the edge of the optical glass 3, the driving motor 3 37 is reversed, so that the two sets of pressing rollers 42 move toward each other along the upper surface of the optical glass 3. The material placement plate 43 is pressed downward and cushioned by the connecting spring 3 65 and the connecting spring 4 67 to prevent the optical glass 3 from being crushed.

[0054] When the two sets of pressure rollers 42 apply too much pressure to the material placement plate 43 by rolling the optical glass 3, the material placement plate 43 drops to abut against the pressure plate 2 53, thereby compressing the connecting spring 2 56 through the pressure column 2 55. At this time, the tooth block 2 54 set on the outer wall of the pressure column 2 55 will drive the driving gear 2 52 to rotate, and the driving gear 2 52 will drive the pressure column 1 49 through the tooth block 1 50 to move upward along the limiting slide block 2 48 and the limiting slide groove 2 45, so that the pressure plate 1 46 abuts against the material placement plate 43 to play a supporting role, and the greater the downward pressure on the material placement plate 43, the greater the supporting force applied by the pressure plate 1 46 to the material placement plate 43, preventing the material placement plate 43 from sinking into the hollow table 44 and being unable to reset.

[0055] The pressurizing assembly 7 can play a role of reverse support when the laminating assembly 6 applies pressure, which not only allows the optical glass 3 to be constantly laminated with the two sets of rollers 42 but also prevents the optical glass 3 from being crushed.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
