Description

Technical Field

[0001] This invention relates to the field of semiconductor processing, and in particular to a strip feeding device for MiniLED processing. Background Technology

[0002] The automotive MiniLED backlight module is a key component for in-vehicle displays. Using MiniLED LEDs as its backlight, it significantly enhances display quality. While essentially still based on LCD technology, its backlight layer consists of thousands of tiny LEDs ranging from 50-200μm in size. These LEDs are divided into hundreds or even thousands of independent dimming zones. Through precise zone control, the brightness of each zone can be adjusted in real-time according to the content displayed, achieving high dynamic contrast and presenting a more realistic picture.

[0003] Double-sided adhesive strips are widely used in the assembly of automotive MiniLED backlight modules. For example, they are required to securely bond components such as iron frames to FPC components and light guide plates to reflectors. Both sides of the double-sided adhesive strip have release paper. The lower release paper is continuous and wound, while the upper release paper is longer than the adhesive strip itself and no less wide. This facilitates the robotic arm's ability to pick up and transport the double-sided adhesive strip to the designated workstation and complete the release operation, enabling automated assembly.

[0004] During the feeding process of the adhesive strip, a stripping knife is usually used in conjunction with a robotic arm to unload the adhesive strip. For the release paper roll continuously wound around the bottom of the adhesive strip, a winding shaft is used to wind it up. During the winding process, the winding end needs to be fixed to the winding paper tube manually. After the winding is finished, it also needs to be removed manually and the winding end fixed. The whole process involves a high degree of manual intervention and low winding efficiency. Summary of the Invention

[0016] Beneficial effects

[0017] 1. This invention uses a peeling mechanism to peel the adhesive strips from the adhesive strip roll. After peeling, the adhesive strips are fed and assembled by a robotic arm. The adhesive strip paper is laid horizontally on the second feeding plate and the peeling knife. During peeling, the robotic arm is needed to grasp the adhesive strips on the adhesive strip paper. When the robotic arm moves to the adhesive strip and adsorbs it, the peeling knife retracts and separates from the second feeding plate, creating a gap. At this time, the peeling knife will drive the bottom film to retract synchronously, while the adhesive strip will be left in the adsorption area of ​​the robotic arm. As the bottom film retracts, the adhesive strip separates from the bottom film, thus realizing the peeling function.

[0018] 2. This invention also includes a winding assembly for winding waste film. The winding assembly has two clamping plates that move outward synchronously with the rectangular sliding plate, bringing the clamping plates closer to the feed chute. The film is inserted into the feed chute and between the two clamping plates, where it is clamped by a spring. The two clamping plates then retract into the winding shaft, and the film is wound up as the shaft rotates. After winding, the arc-shaped push plate moves laterally, pushing the waste film winding cylinder outward a certain distance for easy removal. The invention also includes a tape roll and clamping rods. In use, the clamping rods hold the tape strip and move it to the pasting point for rotation and pressing. The rotation of the waste film winding cylinder wraps the waste film roll, and the clamping rods are heated to melt it, thus fixing the wound film and facilitating its removal from the roll.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1As shown in the figure, an embodiment of the present invention provides a MiniLED processing adhesive strip feeding device, including a base 100, a first feeding shaft 200, a first feeding mechanism 300, a stripping mechanism 400, a feeding mechanism 500, and a waste collection mechanism 600. The base 100 is provided with a roll feeding shaft, on which an adhesive strip roll is placed. The adhesive strip roll has several adhesive strips. In use, the adhesive strip roll is placed on the roll feeding shaft, and then the pull-out end of the adhesive strip roll is pulled to move it. After passing through the first feeding shaft 200, the first feeding mechanism 300, the stripping mechanism 400, and the feeding mechanism 500, the material finally enters the waste collection mechanism 600 for the collection of the bottom film on the rubber strip roll. The stripping mechanism 400 is used to remove the rubber strip from the rubber strip roll, and the waste material after removing the rubber strip is fed into the waste collection mechanism 600 through the feeding mechanism 500 for winding and collection, so as to be recycled for resource reuse. The feeding path 700 is the feeding path of the bottom film on the rubber strip roll.

[0023] Specifically, such as Figure 2 The base 100 shown includes a vertical plate 101 and a base plate 107. A slide rail 108 is fixedly mounted on the base plate 107, and a movable plate 109 is fixedly mounted on the slide rail 108. The movable plate 109 is fixedly connected to the vertical plate 101. A second mounting plate 102 is fixedly mounted at the top of the vertical plate 101. A roll feeding shaft is rotatably mounted on the second mounting plate 102. The roll feeding shaft includes a mounting disc 103, which is circular. A circular shaft 105 is coaxially mounted and fixed on the mounting disc 103. A fixed disc 104 is detachably connected to the end of the circular shaft 105. In use, the roll of adhesive strip is placed on the roll feeding shaft, and the roll feeding shaft can rotate automatically to feed the adhesive strip. The rotation method of the roll feeding shaft includes, but is not limited to, direct drive by a motor.

[0024] like Figure 2 As shown, the first feeding shaft 200 is rotatably mounted on the vertical plate 101. The first feeding mechanism 300 includes a first feeding plate 303 fixedly mounted on the vertical plate 101. First limiting strips 304 are fixedly mounted on both sides of the first feeding plate 303. A first telescopic cylinder 301 is also fixedly mounted on the vertical plate 101 above the first feeding plate 303. A pressure plate 302 is fixedly mounted at the output end of the first telescopic cylinder 301. The first telescopic cylinder 301 controls the pressure plate 302 to move up and down.

[0025] The stripping mechanism 400 includes a first support 401, with a receiving platform 402 fixedly mounted on the top of the first support 401. The stripping mechanism 400 also includes a mounting base 403 fixedly mounted on the moving plate 109. A lead screw 405 is rotatably mounted on the mounting base 403, and a second support 404 is slidably fitted on the lead screw 405. The second support 404 is slidably fitted with the moving plate 109. The other end of the lead screw 405 is connected to a first motor 406. The first motor 406 drives the lead screw 405 to rotate, thereby moving the second support 404. A second feeding plate 407 is fixedly mounted on the top of the second support 404. Second limiting strips 408 are fixedly mounted on both sides of the second feeding plate 407, and a stripping blade 409 is also fixedly mounted on the second feeding plate 407. The second support 404 will drive the stripping blade 409 to move horizontally. The stripping blade 409 is horizontally inserted into the receiving platform 402. A third feeding shaft 411 is rotatably mounted on the second support 404, and a fourth feeding shaft 410 is rotatably mounted on the second support 404. A display screen 106 is also fixedly mounted on the upright plate 101.

[0026] In use, the adhesive strip is laid horizontally on the second feed plate 407 and the peeling knife 409. When peeling, it needs to be done in conjunction with the robotic arm to grab the adhesive strip on the adhesive strip. When the robotic arm moves to the adhesive strip and adsorbs it, the peeling knife 409 retracts and separates from the second feed plate 407, creating a gap. At this time, the peeling knife 409 will drive the bottom film to retract synchronously, while the adhesive strip will be left in the adsorption area of ​​the robotic arm. As the bottom film retracts, the adhesive strip separates from the bottom film, realizing the peeling function.

[0027] like Figure 2 As shown, the feeding mechanism 500 includes a mounting shell 501 fixed on the movable plate 109. Several sets of feeding rollers 502 are rotatably arranged inside the mounting shell 501. One set of feeding rollers 502 is driven by a second motor 503, and the other sets of feeding rollers 502 are rotatably arranged with the mounting shell 501. The feeding mechanism 500 also includes a second feeding shaft 504, which is rotatably connected to the vertical plate 101.

[0028] During use, the adhesive strip enters the first feeding mechanism 300 along the first feeding shaft 200 and is limited by the first limiting strip 304. The pressure plate 302 presses down on the adhesive strip to further limit its position. Then, the adhesive strip enters the peeling mechanism 400 for peeling. The label enters the next process with the robotic arm. The peeled bottom film then enters the feeding mechanism 500 along the fourth feeding shaft 410 and the third feeding shaft 411 in sequence, and contacts the feeding roller 502 in the feeding mechanism 500 in sequence. Finally, it enters the waste collection mechanism 600 through the second feeding shaft 504 for waste winding.

[0029] like Figure 3The waste collection mechanism 600 shown is fixedly installed on the upright plate 101. The waste collection mechanism 600 includes a housing 601, a discharge trough 603 on the top of the housing 601, and a feed trough 602 on the side of the housing 601. Figure 4 The diagram shows a winding assembly rotatably disposed inside the housing 601. The winding assembly is used to wind up the bottom film. Since the bottom film at the winding end needs to be fixed to the winding assembly during winding, conventional winding devices usually involve manually pasting and fixing the bottom film directly to the winding assembly, which is inefficient. In this embodiment, the winding end of the bottom film is fixed by a clamping plate 624.

[0030] Specifically, the winding assembly includes a first mounting plate 619, such as Figure 6 and Figure 9 As shown, the first mounting plate 619 is circular, and a connecting post 639 is coaxially and fixedly mounted on it. A take-up shaft 620 is coaxially and fixedly mounted on the connecting post 639. A continuous hollow groove 622 is formed on the take-up shaft 620 and the connecting post 639 from the center outwards. The end of the hollow groove 622 is located on the first mounting plate 619. The hollow groove 622 makes the take-up shaft 620 open. Limiting grooves 621 are respectively provided on both sides of the hollow groove 622. Figure 7 and 9 As shown, a rectangular sliding plate 623 is slidably mounted on the first mounting plate 619. The rectangular sliding plate 623 is located within the hollow groove 622. This invention provides a sliding method for the first mounting plate 619 and the rectangular sliding plate 623. Specifically, a first gear is rotatably mounted on the bottom of the rectangular sliding plate 623, and a first rack is mounted at a corresponding position on the first mounting plate 619. The first gear meshes with the first rack to achieve sliding of the rectangular sliding plate 623 on the first mounting plate 619, that is, the rectangular sliding plate 623 can move laterally within the hollow groove 622. Figure 7 As shown, the rectangular slide plate 623 is also provided with a limiting groove 626, and a slide rod 628 is fixedly provided in the limiting groove 626. Springs 627 are respectively sleeved at both ends of the slide rod 628, and clamping plates 624 are slidably provided at both ends of the slide rod 628. The two clamping plates 624 are respectively fixedly connected to the springs 627. When the distance between the two clamping plates 624 increases, the clamping plates 624 will squeeze the springs 627. A circular ring 625 is fixedly provided on both clamping plates 624.

[0031] In use, the rectangular slide plate 623 is controlled to move toward the opening end of the hollow groove 622. The two clamping plates 624 will move outward synchronously with the rectangular slide plate 623, so that the clamping plates 624 are close to the feed groove 602. The bottom film is inserted through the feed groove 602 and inserted between the two clamping plates 624. It is clamped by the action of the spring 627. Then the two clamping plates 624 retract into the inside of the take-up shaft 620 and are wound up with the rotation of the take-up shaft 620.

[0032] Under normal conditions, the two clamping plates 624 are always clamped under the action of the spring 627. However, when the two clamping plates 624 move to the vicinity of the feed chute 602, it is necessary to ensure that the two clamping plates 624 are in the open state in order to allow the bottom film to enter between the two clamping plates 624. Specifically, as follows: Figure 4 As shown, two baffles 604 are fixedly installed inside the housing 601 at the feed chute 602. A slot 607 is opened on one side of each baffle 604. Bent circular tubes 605 are fixedly installed above and below the slots 607 inside the housing 601. Figure 11 As shown, the bent circular tube 605 has two bent sections at both ends. The bending angle of the two bent sections is greater than 100 degrees. One set of corresponding bent sections of the two bent circular tubes 605 are kept parallel, while the other set of corresponding bent sections are kept symmetrically open.

[0033] like Figure 11 As shown, when the rectangular slide plate 623 moves toward the baffle 604, the two clamping plates 624 gradually move to the horizontal bending section, and the circular rings 625 on the two clamping plates 624 gradually fit onto the horizontal section of the bent circular tube 605. As the two clamping plates 624 continue to move, the circular rings 625 begin to move along the symmetrical opening section. At this time, the distance between the two clamping plates 624 will increase, and the spring 627 will be compressed. The two clamping plates 624 gradually approach the baffle 604 and are located between the two baffles 604. At this time, the bottom film is continuously inserted between the two baffles 604 and can enter between the two clamping plates 624. As the two clamping plates 624 retract to the winding shaft 620, the spring 627 restores its deformation when the two clamping plates 624 retract. The two clamping plates 624 clamp the bottom film and bring it back to the inside of the winding shaft 620 for fixation. The winding is achieved by rotating the winding shaft 620.

[0034] To facilitate the removal of the bottom film after winding, this embodiment also includes a waste film winding drum 630. The waste film winding drum 630 is hollow inside, and its side wall has a slot 632 corresponding to the hollow groove 622. Limiting blocks 633 are fixedly provided on both sides of the side wall of the waste film winding drum 630 located in the slot 632. The two limiting blocks 633 are slidably disposed in the limiting groove 621. Arc-shaped baffles 631 are provided at both ends of the waste film winding drum 630. When the wound bottom film reaches its limit, the waste film winding drum 630 can be removed and replaced with a new waste film winding drum 630 to achieve continuous winding.

[0035] like Figure 4As shown, in order to realize the rotation of the winding assembly, this embodiment also provides a driving method for the winding assembly. Specifically, two first pulleys 614 are rotatably provided on the housing 601. The two first pulleys 614 are connected by a first synchronous belt 615. One end of one of the first pulleys 614 is coaxially and fixedly connected to the first mounting plate 619 of the winding assembly, and the other end is fixedly connected to the protective block 616. A third motor (not shown in the figure) is connected to the other first pulley 614. The third motor drives the winding assembly to rotate, and finally realizes the winding function.

[0036] like Figure 4 As shown, since the waste winding drum 630 is located inside the housing 601, when the waste winding drum 630 reaches the winding limit, it needs to be taken out and replaced. During the removal process, the operator needs to reach into the housing 601 to pull it out. Since the internal space of the housing 601 is small and there are problems such as the waste winding drum 630 being far from the outlet, it is inconvenient to remove. Therefore, this embodiment also proposes an ejection mechanism to eject the waste winding drum 630 after winding is completed.

[0037] like Figure 4 and Figure 5 As shown, the specific ejection mechanism includes an arc-shaped push plate 613, which is located between the first mounting plate 619 and the rectangular slide plate 623 (ensuring that the arc-shaped push plate 613 will not obstruct the rectangular slide plate 623 when it rotates with the winding assembly). An extension plate 612 is fixedly provided at the bottom of the arc-shaped push plate 613. A side plate 609 is fixedly provided on the back of the housing 601. A first threaded rod 618 is rotatably provided on the side plate 609, and a first limiting rod 617 is fixedly provided. The extension plate 612 is threadedly engaged with the first threaded rod 618 and slidably engaged with the first limiting rod 617. Two second pulleys 610 are also rotatably provided on the side plate 609. The second pulleys 610 are connected by a second synchronous belt 611. One of the second pulleys 610 is coaxial with the first threaded rod 618 and rotates fixedly. One end of the other second pulley 610 is coaxial and fixedly connected to a second gear 608. Figure 8 and Figure 11 As shown, the bottom of the rectangular slide plate 623 is also provided with a second rack 629, which can mesh with the second gear 608 when it moves laterally.

[0038] In use, when the winding reaches its limit, the rectangular slide plate 623 is first driven to move laterally outward a certain distance. During the movement, the second rack 629 will mesh with the second gear 608, and the second gear 608 will rotate. The rotation of the second gear 608 will realize the rotation of the first threaded rod 618 through the second pulley 610 and the second synchronous belt 611. The first threaded rod 618 realizes the lateral movement of the arc-shaped push plate 613 through the extension plate 612. The arc-shaped push plate 613 pushes the waste winding drum 630 outward a certain distance for easy removal (the bottom film between the two clamping plates 624 will also be pulled out during the removal of the waste winding drum 630). After removal, the rectangular slide plate 623 continues to move laterally and open to realize the next material removal.

[0039] Since the end needs to be adhered to the wound base film when it reaches its maximum winding limit to prevent it from loosening, this embodiment also includes an adhesive coating mechanism for securing the wound base film with adhesive, as detailed below. Figure 11 As shown, a tape placement area 634 is provided on the housing 601 at the material feeding groove 603. A tape roll 606 is rotatably clamped in the tape placement area 634, and a tape strip 635 is wound on the tape roll 606. A second telescopic cylinder 638 is also rotatably provided on the housing 601. A clamping mechanism 636 is fixedly provided at the output end of the second telescopic cylinder 638. Two clamping rods 637 are rotatably provided on the clamping mechanism 636. The two clamping rods 637 have a heating function. In use, the tape strip 635 is clamped by the clamping rods 637 and moved to the pasting point for rotation and pressing pasting. In conjunction with the rotation of the waste material take-up drum 630, the waste roll is wrapped, and then melted by heating the clamping rods 637.
