Description

Technical Field

[0001] The utility model relates to the technical field of display modules, and in particular to a bonding device for display modules. Background Art

[0002] In the manufacturing process of display modules, the bonding of the cover plate (usually glass or plastic) and the display unit (such as LCD or OLED panel) is a key process. In traditional large-scale production environments, this process often relies on large-scale equipment with a high degree of automation, such as vacuum bonding machines, hot press bonding machines, etc., which can ensure high-precision and high-speed bonding while reducing the generation of bubbles and impurities, ensuring the consistency and stability of product quality.

[0003] However, in small-batch or customized production scenarios, it is not economical to use large-scale automated equipment, because the high equipment costs and maintenance expenses may not be amortized by the smaller output. Therefore, manual lamination has become a common alternative. Although this method is highly flexible, it also has significant limitations, especially the difficulty in controlling the lamination accuracy. In manual operation, due to differences in operator skills, it is easy to cause position deviation between the cover and the display unit and easily generate bubbles after lamination, which affects the visual effect and service life of the final product. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a bonding device for a display module that can play a positioning function so that the cover plate and the display unit are not easily displaced and bubbles are not easily generated when they are bonded.

[0005] The utility model provides the following technical solutions: a bonding device for display modules, comprising a material placement seat, two protrusions respectively arranged on both sides of the material placement seat, a placement cavity for accommodating a display unit formed between the two protrusions, a positioning mechanism arranged on the material placement seat for positioning the OCA optical glue or the cover plate, and a squeezing mechanism arranged on the material placement seat for removing bubbles;

[0006] The positioning mechanism comprises two positioning units respectively arranged on both sides of the material placement seat, and a driving component for synchronously driving the two positioning units to operate;

[0007] The positioning unit includes a mounting seat arranged on the material placing seat, a sliding block slidably connected to the mounting seat, and a positioning member fixedly connected to the sliding block, and the driving assembly is used to drive the sliding block to move.

[0008] Furthermore, a first sliding groove is provided on the mounting seat, and the sliding block is slidably connected to the mounting seat via the first sliding groove.

[0009] Furthermore, the driving assembly includes a rotating shaft rotatably connected to the mounting seat and the material placing seat in the two positioning units, two threads are respectively arranged on both sides of the rotating shaft, and the rotating shaft is threadedly connected to the sliders in the two positioning units through the two threads.

[0010] Furthermore, one end of the rotating shaft passes through the outer wall of one of the mounting seats, and a knob is fixedly connected to the end of the rotating shaft passing through the outer wall of the mounting seat.

[0011] Furthermore, the extrusion mechanism includes two slide rails respectively arranged on both sides of the material placement seat, a sliding member slidably connected between the two slide rails, two connecting rods arranged at the lower part of the sliding member, and a roller rotatably connected between the two connecting rods.

[0012] Furthermore, two second sliding grooves are provided at the lower part of the sliding member, and the sliding member is slidingly connected to the two connecting rods via the two second sliding grooves, and a spring is connected between the sliding member and the two connecting rods.

[0013] Furthermore, a straight-shaped pulling block is fixedly connected to a side of the sliding member away from the roller.

[0014] The beneficial effects of the utility model are as follows: the cover plate and the OCA optical glue are positioned by the positioning piece, so as to prevent the cover plate from being offset by being attached to the display unit through the OCA optical glue; at the same time, the positioning piece can be driven by the driving assembly to move, so as to prevent the positioning piece from blocking the movement of the roller in the extrusion mechanism; in addition, by pulling the sliding piece to move in the direction close to the placement cavity, the sliding piece drives the connecting rod to move in the direction close to the placement cavity, and the connecting rod drives the roller to move, and the roller presses the OCA optical glue or the cover plate on the placement cavity, thereby squeezing out the bubbles between the cover plate and the OCA optical glue to prevent the generation of bubbles.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] A bonding device for display modules, such as Figure 1-Figure 6 As shown, it comprises a material placement seat 1, two protrusions 2 are respectively arranged on both sides of the material placement seat 1, a placement cavity 3 for accommodating a display unit 4 is formed between the two protrusions 2, a positioning mechanism 7 for positioning the OCA optical glue 5 or the cover plate 6 is arranged on the material placement seat 1, and a squeezing mechanism 8 for removing bubbles is arranged on the material placement seat 1;

[0026] The positioning mechanism 7 includes two positioning units respectively arranged on both sides of the material placement seat 1, and a driving component 74 for synchronously driving the two positioning units to operate;

[0027] The positioning unit includes a mounting seat 71 disposed on the material placement seat 1 , a slider 72 slidably connected to the mounting seat 71 , and a positioning member 73 fixedly connected to the slider 72 . The driving assembly 74 is used to drive the slider 72 to move.

[0028] It can be understood that first, the operator places the display unit 4 into the placement cavity 3. The size of the placement cavity 3 is adapted to the size of the display unit 4, and the depth of the placement cavity 3 is less than the height of the display unit 4. Therefore, after the display unit 4 is placed in the placement cavity 3, it is also convenient for the operator to take the display unit 4 out of the placement cavity 3. Then the operator can operate the driving component 74. The operation of the driving component 74 will drive the two sliders 72 to move toward each other. The two sliders 72 move toward each other and drive the positioning member 73 to move. When the positioning member 73 moves to align with the adjacent protrusion 2, the operator can stop the driving component 74, and the positioning member 73 will also stop operating. At this time, the distance between the two positioning members 73 is equal to the distance between the two sliders 72. The lengths of the placement cavities 3 formed between the protrusions 2 are equal. At this time, the operator can take out the OCA optical glue 5. The OCA optical glue 5 is in a solid form. It is a double-sided tape without a substrate and has high transparency. The protective film on one side of the OCA optical glue 5 is torn off, and then the surface is attached to the display unit 4. The side of the OCA optical glue 5 with the protective film torn off will be tightly attached to the display unit 4. At the same time, the positioning member 73 can prevent the OCA optical glue 5 from being offset during the bonding process with the display unit 4. After the OCA optical glue 5 is attached to the display unit 4, the operator can drive the driving component 74 to drive the two sliders 72 to move in opposite directions, and the movement of the slider 72 drives the positioning member 73 to also The positioning member 73 will move away from the display unit 4. At this time, the operator can operate the squeezing mechanism 8 to press the OCA optical adhesive 5, thereby preventing bubbles from being generated at the position where the OCA optical adhesive 5 and the display unit 4 are fitted. After the squeezing mechanism 8 has pressed the OCA optical adhesive 5, the operator can again drive the driving assembly 74 to drive the positioning member 73 to move toward each other, so that it moves to align with the protrusion 2. After aligning with the protrusion 2, the operator can tear off the protective film on the other side of the OCA optical adhesive 5. The other side is the side away from the display unit 4. At this time, the operator can place the cover plate 6 thereon, and the cover plate 6 can be positioned by the positioning member 73 to prevent the cover plate 6 from passing through the OCA optical adhesive 5. The display unit 4 is fitted to cause an offset. After the cover plate 6 is fitted to the OCA optical glue 5, the operator can operate the driving component 74, and the driving component 74 will drive the positioning member 73 away from the cover plate 6. Then the operator operates the squeezing mechanism 8 to press the cover plate 6, thereby squeezing out the bubbles between the cover plate 6 and the OCA optical glue 5 to prevent the generation of bubbles. After the bubbles are squeezed out, the operator can take out the fitted display module. The display module consists of the display unit 4, the OCA optical glue 5 and the cover plate 6. The OCA optical glue 5 consists of three layers, of which the upper and lower layers are conventional optical glues, and the middle layer is added with optical melanin, thereby making the visual color of the display area and the outside of the CTP window close.

[0029] The mounting seat 71 is provided with a first sliding groove 75 , and the sliding block 72 is slidably connected to the mounting seat 71 via the first sliding groove 75 .

[0030] It can be understood that when the driving assembly 74 drives the slider 72 to move to a position close to the placement chamber 3, the slider 72 moves to the end of the first slide groove 75, that is, one end close to the material placement seat 1. At this time, the positioning member 73 is just aligned with the protrusion 2, which makes it easy for the operator to quickly align the positioning member 73 with the protrusion 2.

[0031] like Figure 4 As shown, the driving assembly 74 includes a rotating shaft 741 rotatably connected to the mounting seat 71 and the material placing seat 1 in the two positioning units, and two threads 742 are respectively arranged on both sides of the rotating shaft 741. The rotating shaft 741 is threadedly connected to the sliders 72 in the two positioning units through the two threads 742.

[0032] It can be understood that the operator can drive the rotating shaft 741 to rotate forward, and the forward rotation of the rotating shaft 741 drives the thread 742 thereon to rotate, and the rotation of the thread 742 drives the slider 72 to move toward a position close to the placement cavity 3. When the operator drives the rotating shaft 741 to rotate reversely, the rotating shaft 741 will drive the thread 742 to rotate reversely, and the reverse rotation of the thread 742 will drive the slider 72 to move away from the placement cavity 3.

[0033] One end of the rotating shaft 741 passes through the outer wall of one of the mounting seats 71 , and a knob 743 is fixedly connected to the end of the rotating shaft 741 passing through the outer wall of the mounting seat 71 .

[0034] It can be understood that the operator can drive the rotating shaft 741 to rotate through the knob 743, thereby making it convenient for the operator to rotate the rotating shaft 741.

[0035] like Figure 5 As shown, the extrusion mechanism 8 includes two slide rails 81 respectively arranged on both sides of the material placement seat 1, a sliding member 82 slidably connected between the two slide rails 81, two connecting rods 84 arranged at the lower part of the sliding member 82, and a roller 85 rotatably connected between the two connecting rods 84.

[0036] It can be understood that the operator can pull the sliding member 82 to move toward the placement cavity 3, the sliding member 82 drives the connecting rod 84 to move toward the placement cavity 3, the connecting rod 84 drives the roller 85 to move, and the roller 85 presses the OCA optical glue 5 or the cover plate 6 on the placement cavity 3. The roller 85 is flexible to prevent damage to the cover plate 6 when pressed.

[0037] like Figure 6As shown, two second sliding grooves 86 are provided at the lower part of the sliding member 82 , and the sliding member 82 is slidingly connected to the two connecting rods 84 via the two second sliding grooves 86 , and a spring 87 is connected between the sliding member 82 and the two connecting rods 84 .

[0038] Among them, when the operator pulls the sliding member 82 to drive the roller 85 to press the OCA optical glue 5 or the cover plate 6, the setting of the spring 87 can make the roller 85 play a buffering role when pressing, and the spring 87 can also apply a downward force to the roller 85, and the roller 85 will achieve the pressing effect more effectively to prevent the generation of bubbles.

[0039] A straight-shaped pulling block 83 is fixedly connected to a side of the sliding member 82 away from the roller 85 .

[0040] By pulling faster, the operator can drive the sliding member 82 to move through the pulling block 83, so that the operator can drive the sliding member 82 to move more conveniently.

[0041] To summarize, the cover plate 6 and the OCA optical glue 5 are positioned by the positioning member 73 to prevent the cover plate 6 from being offset by being attached to the display unit 4 through the OCA optical glue 5. At the same time, the positioning member 73 can be driven by the driving assembly 74 to move, which can prevent the positioning member 73 from blocking the movement of the roller 85 in the extrusion mechanism 8. In addition, by pulling the sliding member 82 to move toward the placement cavity 3, the sliding member 82 drives the connecting rod 84 to move toward the placement cavity 3, and the connecting rod 84 drives the roller 85 to move. The roller 85 presses the OCA optical glue 5 or the cover plate 6 on the placement cavity 3, thereby squeezing out the bubbles between the cover plate 6 and the OCA optical glue 5 to prevent the generation of bubbles.
