Description

Technical Field

[0001] The present invention relates to the technical field of backlight modules, in particular to a jig for attaching double-sided adhesive tape of a backlight module. Background Art

[0002] The casing is a common panel in daily life and is often used on some display devices such as display screens.

[0003] A common backlight panel now includes a light guide plate, a light strip, a double-sided adhesive layer, and a shell. The light strip is arranged on the shell. The double-sided adhesive layer is in the shape of a square frame. One side of the double-sided adhesive layer is attached to the light guide plate, and the other side is attached to the shell, so that the light guide plate is installed on the shell. The common way of attaching the double-sided adhesive is to manually tear off the anti-sticking film on one side of the double-sided adhesive, let the adhesive layer be attached to the shell, and then when the light guide plate is installed, tear off the other layer of anti-sticking film of the double-sided adhesive, and finally attach the light guide plate to the double-sided adhesive layer.

[0004] Regarding the above technical conditions, there is also a defect that since the double-sided tape is made of a relatively soft material, both sides are more likely to shake during the manual attachment process, making it inconvenient to attach the double-sided tape.

[0005] Based on this, the present invention designs a jig for attaching double-sided adhesive tape to a backlight module to solve the above problems. Summary of the Invention

[0009] Preferably, a limit frame is fixedly provided on the placement seat, and the limit frame is sleeved on the outer side of the double-sided adhesive frame.

[0012] By adopting the above technical solution, when the double-sided rubber frame is placed in the limit frame, the four corners of the lower isolation layer are peeled off from the contact with the rubber layer. When the rubber frame is placed on the mounting seat, the resistance block is pressed on the upper surface of the lower isolation layer. When the adsorption plate rises, the resistance block presses against the lower isolation layer.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] The following is combined with Figure 1-8 This application is described in further detail.

[0037] A jig for attaching double-sided tape to a backlight module comprises a mounting base 1 for placing a double-sided tape frame, a placement base 2 for placing a housing, and a mounting frame. A guide rod 3 is fixedly connected to the mounting base 1. The double-sided tape frame comprises an upper isolation layer 4, an adhesive layer 5, and a lower isolation layer 6. The guide rod 3 is fixedly connected to the placement base 2. The mounting frame comprises a vertical plate 7 and a horizontal plate 8. The vertical plate 7 is fixedly connected to the horizontal plate 8. The lower end of the vertical plate 7 is fixedly connected to the mounting base 1. The horizontal plate 8 is fixedly connected to a fixing plate 9. The fixing plate 9 has a movable opening 10 in the form of a square groove. The guide rod 3 is a direction rod and is sleeved on the guide rod 3.

[0038] A first cylinder 11 is vertically fixedly connected to the horizontal plate 8. An adsorption plate 12 is fixedly provided on the telescopic shaft of the first cylinder 11. An air suction hole 13 is provided on the adsorption plate 12. A ventilation cavity 14 is provided on the adsorption plate 12. The ventilation cavity 14 is communicated with the air suction hole 13. No air suction hole 13 is provided on the four corners of the adsorption plate 12. An air suction pipe 15 is connected to the adsorption plate 12. One end of the air suction pipe 15 is fixedly connected to the air pump. The air suction pipe 15 is communicated with the ventilation cavity 14. A plurality of air suction holes 13 are provided on the adsorption plate 12. A connecting plate 16 is fixedly provided on the placement seat 2. A motor 17 is fixedly provided on the connecting plate 16. A rotating rod 18 is coaxially fixedly provided on the rotating shaft of the motor 17. A movable plate 19 is fixedly provided on the vertical plate 7. A movable hole 20 is provided on the movable plate 19. The movable hole 20 is threadedly connected to the rotating rod 18.

[0039] A limit frame 21 is fixedly provided on the placement seat 2, and the double-sided adhesive frame is placed in the limit frame 21. The limit frame 21 can reduce the movement of the double-sided adhesive frame. The four corners of the limit frame 21 are provided with mounting openings 22. The placement seat 2 is provided with a movable groove 23. A sliding block 24 is movably provided on the movable groove 23, and a resistance block 38 is provided on the sliding block 24. An anti-slip groove 26 is provided on the groove wall of the movable groove 23. An anti-slip block 25 is fixedly provided on the sliding block 24. The anti-slip block 25 is located in the anti-slip groove 26. The anti-slip block 25 is located in the anti-slip groove 26 and can prevent the resistance block 38 from escaping from the movable groove 23. A clearance groove 27 is provided on the resistance block 38, and a resistance rod 28 is inserted into the clearance groove 27. A plug hole 29 is provided on the mounting seat 1.

[0040] When the double-sided rubber frame is placed in the limit frame 21, the four corners of the lower isolation layer 6 are manually peeled off from the contact with the rubber layer 5. When the rubber frame is placed on the mounting seat 1, the resistance block 38 is pressed against the upper surface of the lower isolation layer 6, and the resistance rod 28 is inserted into the clearance groove 27 and the insertion hole 29. When attaching the double-sided rubber frame, the first cylinder 11 is driven to make the adsorption plate 12 rise. The four corners of the lower isolation layer 6 are pressed tightly by the resistance block 38. At the same time, the resistance rod 28 is in contact with the inner side wall of the lower isolation layer 6, which can further prevent the lower isolation layer 6 from separating from the resistance block 38, making the lower isolation layer 6 unable to move. As the adsorption plate 12 continues to rise, the four corners of the rubber layer 5 gradually separate from the lower isolation layer 6 until the lower isolation layer 6 is completely separated from the rubber layer 5, achieving the effect of peeling the lower isolation layer 6.

[0041] After the lower isolation layer 6 is separated from the adhesive layer 5, the motor 17 is driven to rotate the rotating rod 18, thereby driving the mounting frame to move toward the side of the placement seat 2 until the adsorption plate 12 is located above the protective shell. The first cylinder 11 is driven to press the adsorption plate 12 downward, allowing the adhesive layer 5 to be adsorbed on the protective shell, thereby achieving the effect of convenient attachment of double-sided tape.

[0042] A pad 30 is fixedly provided on the mounting base 1, and the lower isolation layer 6 is placed on the pad 30. The pad 30 and the abutment block 38 are at the same height. When the double-sided adhesive frame is placed, the pad 30 can support the double-sided adhesive frame, thereby ensuring that the suction hole 13 can be fully adsorbed on the upper surface of the upper isolation layer 4 and the four corners of the lower isolation layer 6 do not contact the pad 30. Adsorption holes 31 are provided on the pad 30, and an adsorption cavity 32 is provided in the pad 30. A vent pipe 33 is fixedly connected to the pad 30, one end of which is also connected to the vacuum pump. The vent pipe 33 is in communication with the adsorption cavity 32, and the adsorption holes 31 are in communication with the adsorption cavity 32. When the double-sided adhesive frame is placed on the pad 30, the vent holes adsorb the lower isolation layer 6 tightly. When the four corners of the lower isolation layer 6 are peeled off, the vent holes adsorb on the lower isolation layer 6, which can prevent the double-sided adhesive frame from moving, thereby facilitating the peeling of the four corners of the lower isolation layer 6.

[0043] It should be noted that when the adsorption plate 12 adsorbs the upper isolation layer 4 and rises, the adsorption holes 31 no longer adsorb the lower isolation layer 6. A release layer 36 is fixedly disposed on the upper surface of the abutment block 38. The release layer 36 is made of the same material as the lower isolation layer 6. When the abutment block 38 abuts the lower isolation layer 6, the release layer 36 can reduce the adhesion of the adhesive layer 5 to the abutment block 38.

[0044] An air extraction tube 34 is fixedly mounted on the adsorption plate 12. Suction holes 35 are formed on the adsorption plate 12. Suction tubes are located at the four corners of the adsorption plate 12 and communicate with the suction holes 35. When the upper insulating layer 4 is positioned on the mounting base 1, the suction holes 35 and the air intake holes 13 jointly absorb the upper insulating layer 4. After the adhesive layer 5 is attached to the protective shell, the air intake holes 13 cease absorbing the upper insulating layer 4, while the suction holes 35 continue to absorb the upper insulating layer 4. When the adsorption plate 12 rises, the suction holes 35 absorb the upper insulating layer 4 and detach it from the adhesive layer 5. As the adsorption plate 12 continues to rise, the upper insulating layer 4 gradually detaches from the adhesive layer 5, facilitating the peeling of the upper insulating layer 4.

[0045] The mounting base 1 is provided with a placement groove 37, in which the protective shell is placed. The placement groove 37 can reduce the movement of the protective shell and stabilize the placement of the protective shell.

[0046] The implementation principle of this embodiment is: when attaching the double-sided adhesive frame, the first cylinder 11 is driven to make the adsorption plate 12 rise, and the four corners of the lower isolation layer 6 are pressed tightly by the resistance block 38. At the same time, the resistance rod 28 is in resistance against the inner side wall of the lower isolation layer 6, which can further prevent the lower isolation layer 6 from separating from the resistance block 38, making the lower isolation layer 6 unable to move. During the continuous rise of the adsorption plate 12, the adhesive layer 5 at the four corners gradually separates from the lower isolation layer 6 until the lower isolation layer 6 is completely separated from the adhesive layer 5, thereby achieving the effect of peeling off the lower isolation layer 6.

[0047] After the lower isolation layer 6 is separated from the adhesive layer 5, the motor 17 is driven to rotate the rotating rod 18, thereby driving the mounting frame to move toward the side of the placement seat 2 until the adsorption plate 12 is located above the protective shell. The first cylinder 11 is driven to press the adsorption plate 12 downward, allowing the adhesive layer 5 to be adsorbed on the protective shell, thereby achieving the effect of convenient attachment of double-sided tape.
