Description

Technical Field

[0001] This invention relates to the field of backlight module processing technology, and in particular to a backlight adhesive strip applicator for display module processing. Background Technology

[0002] In the production of backlight back panels, adhesive strips need to be attached to the U-shaped folds of the product. Currently, this is typically done manually, which is slow, reduces production efficiency, and is costly. Chinese utility model patent CN217916844 U discloses a backlight back panel adhesive strip attachment device. This device addresses the problems of slow manual application, reduced production efficiency, high labor costs, inconvenience, and susceptibility to errors leading to quality issues. The device includes a workbench with a material-picking component for adsorbing adhesive strips from a placement table. This component includes an adsorption plate and a rotating disk that drives the adsorption plate. A feeding component is located on one side of the workbench along its width and includes a first sliding rail vertically mounted on the workbench and a second sliding rail slidably connected perpendicularly to the first sliding rail. The rotating disk is slidably mounted on the first sliding rail and positioned opposite to the second sliding rail.

[0003] However, its structure is complex and it is not convenient or quick to operate. Therefore, the inventor has made improvements based on the above reasons and hereby submits this application. Summary of the Invention

[0004] To address the technical problems mentioned in the background art, the present invention provides a backlight adhesive strip application device for display module processing.

[0005] This invention is achieved using the following technical solution: a backlight adhesive strip application device for display module processing, comprising a substrate and an application assembly. The substrate is provided with a positioning mechanism for fixing the product, and two guide rails are symmetrically arranged along its width on the top surface of the substrate; the application assembly includes a support frame and a manual application mechanism, wherein the bottom of the support frame is slidably connected to the two guide rails, and the manual application mechanism is mounted on the support frame and used for applying the adhesive strip.

[0006] As a further improvement to the above solution, the positioning mechanism includes two side baffles II and one side baffle I. The two side baffles II are symmetrical and parallel to the guide rail, while the side baffle I is perpendicular to the side baffles II. Correspondingly, three rows of positioning holes I are respectively provided on the base plate, and the arrangement direction of each row of positioning holes I is consistent with the sliding direction of the corresponding side baffles II and side baffles I.

[0007] As a further improvement to the above scheme, both side baffle one and side baffle two are provided with strip grooves, and positioning bolts are inserted in the strip grooves to fix the position of side baffle one or side baffle two.

[0008] As a further improvement to the above scheme, the length of the strip groove is greater than the diameter of the positioning bolt.

[0009] As a further improvement to the above solution, the manual attachment mechanism includes a pressure plate, a mounting plate, and an adhesive strip adsorption plate. The pressure plate and the mounting plate are arranged in parallel and located on the upper and lower sides of the support frame, respectively. The pressure plate and the mounting plate are connected by at least two connecting rods, which slide through the support frame. The adhesive strip adsorption plate is connected below the mounting plate to adsorb the adhesive strip.

[0010] As a further improvement to the above solution, at least one set of adjusting members is installed on the support frame. The top of the adjusting member is used to abut against the bottom surface of the pressure plate, thereby controlling the stroke of the pressure plate.

[0011] As a further improvement to the above solution, the adjusting component is an adjusting bolt that is screwed onto the support frame.

[0012] As a further improvement to the above solution, two sliding seats are provided on the bottom of both sides of the support frame, which are slidably connected to the two guide rails respectively. The sliding seats and the guide rails are slidably connected by a groove opened on the side of the guide rail and a slider fixed inside the sliding seat.

[0013] As a further improvement to the above solution, the sliding seat is provided with a through hole, and several positioning holes are distributed along the length of the guide rail. The position of the sliding seat is fixed by installing a positioning component at the through hole and the positioning hole.

[0014] As a further improvement to the above solution, positioning bolts or positioning pins can be used as positioning components.

[0015] The sliding seat has a cavity, in which a movable partition is slidably installed and sealed to the inner wall. The top surface of the guide rail has a movable groove along its length, and the opposite side walls of the movable groove have grooves. A positioning plate is slidably installed in the groove. The bottom surface of the movable partition has a positioning part that can extend into the movable groove. The opposite sides of the positioning part have positioning slots. When the positioning part extends into the movable groove, the positioning plate can be inserted into the positioning slot.

[0016] A connecting frame is fixed at the bottom of the connecting rod connecting the pressure plate and the mounting plate. A piston cylinder is fixed on the sliding seat. A piston is installed inside the piston cylinder. The piston is connected to the bottom of the connecting frame, and the piston cylinder at the bottom of the piston communicates with the cavity. Thus, the piston moves to squeeze the movable partition in the cavity.

[0017] The bottom of the movable groove is also provided with an installation base groove, and the top of the installation base groove is provided with an elastic isolation pad. The space below the isolation pad is connected by a connecting hole and a groove in the guide slide rail, so that the positioning part presses down and drives the squeezing part at its bottom to squeeze the isolation pad, thereby increasing the air pressure in the groove and pushing the positioning plate into the positioning slot of the positioning part.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] This invention discloses a backlight adhesive strip application device for display module processing, comprising a substrate and an application assembly. The substrate has a positioning mechanism for fixing the product, and two guide rails symmetrically arranged along its width are disposed on the top surface of the substrate. The application assembly includes a support frame and a manual application mechanism, wherein the bottom of the support frame is slidably connected to the two guide rails, and the manual application mechanism is mounted on the support frame and used for applying the adhesive strip.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example 1:

[0029] Reference Figure 1 This solution proposes a backlight adhesive strip application device for display module processing, comprising a substrate 1 and an application assembly. The substrate 1 is provided with a positioning mechanism for fixing the product, and two guide rails 10 are symmetrically arranged on the top surface of the substrate 1 along its width direction; the application assembly includes a support frame 2 and a manual application mechanism, wherein the bottom of the support frame 2 is slidably connected to the two guide rails 10, and the manual application mechanism is mounted on the support frame 2 and is used to apply the adhesive strip.

[0030] In an optional embodiment of the present invention, the positioning mechanism includes two side baffles 9 and one side baffle 3. The two side baffles 9 are symmetrical and parallel to the guide rail 10, while the side baffle 3 is perpendicular to the side baffles 9. Correspondingly, three rows of positioning holes 6 are respectively provided on the base plate 1, and the arrangement direction of each row of positioning holes 6 is consistent with the sliding direction of the corresponding side baffles 9 and 3. The adjustable side baffles 9 and 3 can easily adapt to products of different specifications, making operation convenient, quick, and widely applicable.

[0031] To further facilitate position adjustment, a strip groove (not shown) is provided on both side baffle 3 and side baffle 9. A positioning bolt 8 is inserted through the strip groove, and the position of side baffle 3 or side baffle 9 is fixed by the positioning bolt 8.

[0032] Furthermore, the length of the strip groove is greater than the diameter of the positioning bolt 8, which facilitates fine-tuning of the positions of the side baffle 1 3 and the side baffle 2 9.

[0033] In an optional embodiment of the present invention, the manual attachment mechanism includes a pressure plate 5, a mounting plate 7, and an adhesive strip adsorption plate. The pressure plate 5 and the mounting plate 7 are arranged in parallel and located on the upper and lower sides of the support frame 2, respectively. The pressure plate 5 and the mounting plate 7 are connected by at least two connecting rods (not shown). The connecting rods slide through pre-drilled holes in the support frame 2, and the adhesive strip adsorption plate is connected below the mounting plate 7 to adsorb the adhesive strip. This allows for convenient manual pressing of the pressure plate 5, which drives the mounting plate and the adhesive strip on it to be pressed down and adhered to the designated position of the product, making the operation convenient.

[0034] As an optional embodiment of the present invention, at least one set of adjusting members 4 are installed on the support frame, and the top of the adjusting member 4 is used to abut against the bottom surface of the pressure plate 5, thereby controlling the stroke of the pressure plate 5.

[0035] It is worth mentioning that the adjusting component 4 is an adjusting bolt that is screwed onto the support frame 2.

[0036] In an optional embodiment of the present invention, the bottom of both sides of the support frame 2 is provided with two sliding seats 14, which are slidably connected to the two guide rails 10 respectively. The sliding seats 14 and the guide rails 10 are slidably connected by a groove 25 formed on the side of the guide rail 10 and a slider 21 fixed inside the sliding seat 14. This facilitates position adjustment and is beneficial for accurate application of the adhesive strip.

[0037] Specifically, the sliding seat 14 is provided with a through hole, and the guide rail 10 has a plurality of positioning holes 15 distributed along its length. By installing positioning elements at the through holes and positioning holes 15, the position of the sliding seat 14 is fixed. As an optional embodiment of the present invention, the positioning elements may be positioning bolts or positioning pins.

[0038] Example 2:

[0039] Reference Figure 2 -4. Unlike embodiment 1, this application does not require the use of positioning holes 15 and positioning components for fixing. In this solution, a cavity 16 is provided in the sliding seat 14. A movable partition 17 is slidably installed in the cavity 16 and sealed to its inner wall. A movable groove is provided on the top surface of the guide rail 10 along its length. Grooves 20 are provided on the opposite side walls of the movable groove. A positioning plate 20 is slidably arranged in the groove 20. A positioning part 19 is fixed on the bottom surface of the movable partition 17. The positioning part 19 can extend into the movable groove. A positioning slot 18 is provided on the opposite sides of the positioning part 19. When the positioning part 19 extends into the movable groove, the positioning plate 20 can be inserted into the positioning slot 18.

[0040] A connecting frame 11 is fixed at the bottom of the connecting rod connecting the pressure plate 5 and the mounting plate 7. A piston cylinder 12 is fixed on the sliding seat 24. A piston 13 is installed inside the piston cylinder 12. The piston 13 is connected to the bottom of the connecting frame 11, and the piston cylinder 12 at the bottom of the piston 13 communicates with the cavity 16. Thus, the piston 13 moves to squeeze the movable partition 17 in the cavity 16.

[0041] The bottom of the movable groove is also provided with a mounting base groove 23, and the top of the mounting base groove 23 is provided with an elastic isolation pad 24. The space below the isolation pad 24 is connected to the groove 20 through the connecting hole 22 opened in the guide slide rail 10, so that the positioning part 19 presses down and drives the squeezing part 26 at its bottom to squeeze the isolation pad 24, thereby increasing the air pressure in the groove 20, thereby pushing the positioning plate 27 to be inserted into the positioning slot 18 of the positioning part 19.

[0042] With the above solution, once the sliding seat 14 slides to the designated position on the guide rail 10, no positioning is required. At this time, pressing the pressure plate 5 can drive the connecting rod to press down, causing the connecting frame 11 to drive the piston 13 to move, thereby causing the movable partition to move downwards. Figure 4 At this point, the gas in the groove 20 pushes the positioning plate 27 into the positioning slot 18, thereby fixing the position of the sliding seat 14 and the guide rail 10 under the action of friction, making the operation more convenient and faster, and further improving work efficiency.

[0043] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
