Description

Technical Field

[0001] The present invention relates to the field of curved screen bonding, and more specifically, to a curved surface vacuum bonding machine. Background Art

[0002] During the processing of liquid crystal displays, it is necessary to bond the glass outer screen to the substrate. This bonding process usually involves coating an adhesive layer (such as OCA optical adhesive) between the two, and then pressing and bonding through the pressing head of the bonding machine.

[0003] However, with the development of the industry, more and more liquid crystal displays adopt a curved screen design, that is, the upper end surface of the glass outer screen has a curved surface. Therefore, the pressing head of the conventional bonding machine cannot effectively bond the curved surface of the curved screen, which results in the generation of a bubble band at the junction of the upper end surface and the curved edge of the curved screen during the pressing process, and the bonding of the curved edge of the curved screen is not firm, prone to gaps, and there is no effective limiting structure for curved screens of different sizes, resulting in displacement during the bonding process.

[0004] To solve the above problems, some solutions have also been proposed in the prior art. For example, the Chinese patent application with the publication number CN109116595A discloses an efficient curved surface bonding machine. This device presses and bonds the curved surface screen through a pressing plate. However, since the pressing plate and the curved surface screen are in full contact under force, if there are bubbles between the curved surface screen and the substrate, the bubbles cannot be excluded between the curved surface screen and the substrate through the extrusion force, and the bubbles still remain between the curved surface screen and the substrate.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1 to 9 , a curved surface vacuum laminating machine, including a base 1, side plates 2 fixedly connected to both sides of the base 1, a top plate 3 fixedly connected to the top of the side plates 2, a hydraulic push rod 4 fixedly connected to the lower surface of the top plate 3, and a push-pressing and exhaust assembly 5 fixedly connected to the output end of the hydraulic push rod 4 for removing air bubbles.

[0042] As Figure 2 - Figure 4 shown, the push-pressing and exhaust assembly 5 includes a mounting frame 51 fixed to the output end of the hydraulic push rod 4, a servo motor 52 fixedly connected to one side of the mounting frame 51, a first bidirectional threaded rod 53 fixedly connected to the output end of the servo motor 52, two second springs 58 fixed in the middle of the inner top of the mounting frame 51, a pressure plate 59 fixedly connected to the bottom of the two second springs 58, a sleeve plate 55 threadedly connected to the outer surface of the first bidirectional threaded rod 53, a moving plate 54 sleeved on the outer surface of the sleeve plate 55, two third springs 511 fixedly connected to the inner bottom of the moving plate 54, and a scraper 510 fixedly connected to the bottom of the moving plate 54.

[0043] The front and rear sides of the inner surface of the mounting frame 51 are provided with limiting grooves. The pressing plate 59 is located inside the limiting grooves and slides. One side of the first bidirectional threaded rod 53 is connected to one side of the inner surface of the mounting frame 51 through a bearing. The mutually remote sides of the two sleeve plates 55 are fixedly connected with a radiation heating assembly 56. Both sides of the mounting frame 51 are connected with an adjusting assembly 57. An arc-shaped pressing plate 512 is connected to the adjusting assembly 57. A roller is rotatably connected to the lower surface of the scraping plate 510. The upper surface of the base 1 is connected with a fixing assembly 6 for fixing the substrate.

[0044] When the curved screen and the substrate are squeezed and bonded, the curved screen and the substrate are placed on the fixing assembly 6. The hydraulic push rod 4 is opened to drive the whole mounting frame 51 to move downward. During the movement, the bottoms of the pressing plate 59 and the scraping plate 510 come into contact with the surface of the curved screen in advance. The mounting frame 51 continues to move, so that the second spring 58 and the third spring 511 are compressed to generate elastic forces. The second spring 58 applies the elastic force to the curved screen through the pressing plate 59, and the third spring 511 applies the force to the curved screen through the moving plate 54 and the scraping plate 510. The pressing plate 59 presses the middle part of the curved screen. Then the servo motor 52 is turned on to drive the first bidirectional threaded rod 53 to rotate. The first bidirectional threaded rod 53 drives the two sleeve plates 55 to move away from each other through the action of the threads. The sleeve plates 55 drive the scraping plate 510 to slide on the surface of the curved screen through the moving plate 54. The scraping plate 510 moves towards both sides. The scraping plate 510 moves from the middle to both sides, driving the air bubbles existing between the curved screen and the substrate to both sides, so as to discharge the air bubbles before pressing and solve the drawback that the air bubbles cannot be discharged in the overall pressing of the prior art. The mounting frame 51 continues to move downward a certain distance, driving the arc-shaped pressing plate 512 to contact and press the arc edge of the curved screen. At the same time, the curved screen receives a greater pressing force. The servo motor 52 drives the first bidirectional threaded rod 53 to rotate forward and backward, thereby driving the moving plate 54 and the scraping plate 510 to move back and forth on the curved screen for pressing, improving the bonding quality.

[0045] As Figure 2 - Figure 5 As shown in the figure, the radiation heating assembly 56 includes a slide rail 561 fixed to one side of the sleeve plate 55, two rectangular frames 567 fixed to the front side of the mounting frame 51, and two first through grooves 569 opened on the front side of the inner surface of the mounting frame 51. Both the inner top and the inner bottom of the rectangular frame 567 are fixedly connected with two first racks 568. One side of the slide rail 561 is rotatably connected with a second bidirectional threaded rod 565. The outer surface of the second bidirectional threaded rod 565 is threadedly connected with an internally threaded sleeve block 562. One side of the internally threaded sleeve block 562 is fixedly connected with a lamp holder 563. A radiation lamp group 564 is fixedly connected to the lower surface of the lamp holder 563. One side of the second bidirectional threaded rod 565 is fixedly connected with a gear 566. The gear 566 is located inside the rectangular frame 567 and meshes with the first rack 568.

[0046] One side of the internal-thread sleeve block 562 slides inside the slide rail 561, one side of the second bidirectional threaded rod 565 penetrates through the first through groove 569 and slides mutually, the gear 566 is located inside the rectangular frame body 567, the rectangular frame body 567 is in front of the first through groove 569, the upper and lower first rack bars 568 are arranged at intervals in sequence, the radiation lamp group 564 is composed of an ultraviolet radiation lamp and an infrared radiation lamp, and the ultraviolet radiation lamp and the infrared radiation lamp are arranged alternately in sequence on the lamp base 563.

[0047] During the fitting process, the temperature is also an important influencing factor for the fitting quality of the curved screen and the base body. When the moving plate 54 drives the squeegee 510 to slide on the surface of the curved screen, the radiation lamp group 564 is turned on to work, and the sleeve plate 55 drives the slide rail 561 and the second bidirectional threaded rod 565 to move. The second bidirectional threaded rod 565 drives the gear 566 to move inside the rectangular frame body 567. When the gear 566 contacts the upper first rack bar 568, the gear 566 reverses to drive the second bidirectional threaded rod 565 to reverse, thereby driving the two internal-thread sleeve blocks 562 to move away from each other on the surface of the second bidirectional threaded rod 565, driving the two groups of radiation lamp groups 564 to move away from each other. When the gear 566 leaves the upper first rack bar 568 and contacts the lower first rack bar 568, the gear 566 rotates forward, driving the two internal-thread sleeve blocks 562 to slide close to each other inside the slide rail 561. In this way, the second bidirectional threaded rod 565 rotates forward and backward continuously. When the gear 566 moves to the end of the rectangular frame body 567, the sleeve plate 55 will move in the opposite direction, so that the gear 566 moves in the opposite direction inside the rectangular frame body 567, and the gear 566 drives the second bidirectional threaded rod 565 to rotate forward and backward continuously. Finally, the radiation lamp group 564 moves away from and close to each other continuously, so that the radiation lamp group 564 can irradiate the curved screen in all directions, quickly increase the temperature of the curved screen, make it evenly heated, and further improve the adhesion between the curved screen and the base body.

[0048] As Figure 2 、 Figure 6 and Figure 7 shown, the adjusting assembly 57 includes support sliding grooves 576 opened on the front and rear sides inside the installation frame 51, second rack bars 571 sliding on both sides inside the installation frame 51, and fixing plates 577 fixed on both sides of the installation frame 51. A telescopic rod 574 is slidably connected inside the fixing plate 577. A third rack bar 572 is fixedly connected to the bottom of the telescopic rod 574. A first spring 575 is sleeved on the outer surface of the telescopic rod 574. A support sliding rod 573 is slidably connected inside the support sliding groove 576.

[0049] The bottom of the support slide bar 573 is fixedly connected to both sides of the outer surface of the arc-shaped pressing plate 512. One side of the lower surface of the second rack 571 is fixedly connected to the middle of the outer surface of the arc-shaped pressing plate 512. The third rack 572 meshes with the second rack 571. The top and bottom of the first spring 575 are respectively fixedly connected to the fixed plate 577 and the third rack 572.

[0050] However, when pressing curved screens of different specifications, the arc-shaped pressing plate 512 also needs to be adjusted in position. At this time, the telescopic rod 574 can be pulled upward to drive the third rack 572 and the second rack 571 to move away from each other, releasing the fixing effect on the second rack 571. Then, the second rack 571 is pulled to drive the arc-shaped pressing plate 512 to move, so that the distance between the two arc-shaped pressing plates 512 is the same as the width of the curved screen to be pressed. Thus, the arc edges of the curved screen can be effectively pressed, effectively improving the practicability of the laminator.

[0051] As Figure 8 and Figure 9 As shown, the fixing assembly 6 includes the spring telescopic rods 61 and the damping rods 62 fixed on both sides of the upper surface of the base 1, and the support plates 65 fixed on the front and rear sides of the base 1. The upper surface of the support plate 65 is hinged with the hinge rod 610. The upper surfaces of the spring telescopic rods 61 and the damping rods 62 are fixedly connected with the placement plate 63. Second through grooves 66 are formed in the front and rear sides of the upper surface of the placement plate 63. Slide plates 68 are slidably connected to the front and rear sides of the lower surface of the placement plate 63. Two clamping plates 67 are fixedly connected to the upper surface of the slide plate 68. The clamping plates 67 are inside the second through grooves 66. A fixing member is fixedly connected to the middle of the upper surface of the base 1. Limiting assemblies 69 are slidably connected to both sides of the upper surface of the placement plate 63. The other end of the hinge rod 610 is hinged with one side of the slide plate 68.

[0052] The fixing member includes a fixing frame 64 fixed in the middle of the upper surface of the base 1 and two second barbed racks 613 fixed in the middle of the lower surface of the placement plate 63. First barbed racks 611 are slidably connected to both sides of the fixing frame 64. Two fourth springs 612 are fixedly connected to the mutually approaching sides of the two first barbed racks 611. The second barbed rack 613 meshes with the first barbed rack 611.

[0053] When laminating a curved screen, the traditional way to clamp the curved screen is to rotate the threaded rod to clamp both sides of the curved screen. This clamping method is time-consuming, and excessive force may cause the side of the curved screen to crack.

[0054] Place the curved screen in the processing area on the placement plate 63, press the entire placement plate 63 downward, drive the two second thorn racks 613 to move downward on the surface of the first thorn rack 611. At the same time, the placement plate 63 drives the sliding plate 68 to move downward, and the sliding plate 68 drives one end of the hinge rod 610 to move downward. Thus, one end of the hinge rod 610 pushes the sliding plate 68 to move below the placement plate 63. The two sliding plates 68 approach each other, respectively driving the two clamping plates 67 to move inside the second through groove 66, approaching and clamping the curved screen. At this time, the placement plate 63 cannot continue to move. Since the second thorn rack 613 is engaged by the first thorn rack 611, the second thorn rack 613 cannot move upward, so that the placement plate 63 is fixed, and the curved screen is also fixed. The curved screen is quickly clamped, thus saving a large amount of clamping time and improving work efficiency.

[0055] As Figure 6 and Figure 8 As shown, the limit component 69 includes limit sliding grooves 691 opened on both sides of the upper surface of the placement plate 63. A limit plate 692 is slidably connected inside the limit sliding groove 691. A connecting rod 694 is fixedly connected to the outer sides of the two limit plates 692 away from each other. A connecting slide rail 693 is slidably connected to the outer side of the connecting rod 694. The top of the connecting slide rail 693 is fixedly connected to the lower surface of the other side of the second rack 571.

[0056] The groove of the connecting slide rail 693 is a T-shaped groove, and the connecting rod 694 is slidably connected to the connecting slide rail 693.

[0057] When effectively and quickly clamping the curved screen, it is necessary to restrict all around it to prevent some areas of the curved screen from not being well pressed, resulting in a decrease in the fitting quality or even a separation situation.

[0058] When adjusting the distance between the arc-shaped pressing plates 512, the second rack 571 will slide inside the installation frame 51. During the sliding, it will drive the connecting slide rail 693 to move synchronously. The connecting slide rail 693 drives the limit plate 692 to slide inside the limit sliding groove 691 through the connecting rod 694, so that the distance between the two limit plates 692 is consistent with the length of the curved screen to be fitted. When the second rack 571 is fixed after adjustment, the connecting slide rail 693 is fixed at the same time, so that the limit plate 692 cannot move. Thus, when placing the curved screen, both sides are limited by the limit plates 692, making it more accurately placed in the processing area, so that the curved screen and the base are more effectively fitted;

[0059] Usage method: First, by pushing the squeegee 510 on the exhaust assembly 5 to move from the middle to both sides on the curved screen, the air bubbles between the curved screen and the substrate can be effectively expelled. At the same time, the squeegee 510 will continuously move back and forth on the curved screen, which can effectively bond the curved screen. Under the action of the irradiation of the radiation lamp group 564, the curved screen can be quickly and comprehensively heated, further improving the bonding degree between the curved screen and the substrate. By adjusting the assembly 57, the distance between the two arc-shaped pressing plates 512 can be effectively adjusted, so that the arc-shaped pressing plates 512 can press the arc edges of curved screens with different widths, thereby ensuring the bonding degree of the curved screen and the practicability of the laminator.

[0060] Through the fixing assembly 6, the placing plate 63 can be pressed downward to quickly press the front and back sides of the curved screen, reducing the time for fixing the curved screen. Through the mutual meshing between the first barbed rack 611 and the second barbed rack 613, the placing plate 63 is effectively fixed. At the same time, it is limited by the two limiting plates 692 of the limiting assembly 69, making the curved screen more stable during bonding, with higher processing accuracy and further improved processing quality.

[0061] The above is only a preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
