Description

Technical Field

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

[0002] During the processing of LCD screens, the glass outer screen needs to be bonded to the substrate. The bonding process usually involves applying a layer of glue (such as OCA optical glue) between the two, and then pressing them together with the pressing head of the bonding machine.

[0003] However, with the development of the industry, more and more LCD screens adopt a curved screen design, that is, there is a curved surface on the upper end surface of the glass outer screen. Therefore, the pressure head of a conventional laminating machine cannot effectively bond the curved surface of the curved screen. This results in a bubble zone at the junction of the upper end surface of the curved screen and the curved edge during the laminating process, and the curved edge of the curved screen is not firmly bonded, which easily leads to gaps. There is no effective limiting structure for curved screens of different sizes, and displacement will occur during the bonding process.

[0004] In order to solve the above problems, some solutions have been proposed in the prior art. For example, Chinese patent application with publication number CN109116595A discloses an efficient curved surface bonding machine. The device presses and bonds the curved screen by means of a pressing plate. However, since the pressing plate and the curved screen are in full force contact, if there are bubbles between the curved screen and the substrate, the bubbles cannot be removed between the curved screen and the substrate by the squeezing force, so that the bubbles still remain between the curved screen and the substrate.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 9 A curved surface vacuum laminating machine includes a base 1, two sides of the base 1 are fixedly connected to side panels 2, the top of the side panels 2 is fixedly connected to a top panel 3, the lower surface of the top panel 3 is fixedly connected to a hydraulic push rod 4, and the output end of the hydraulic push rod 4 is fixedly connected to a pushing and exhausting component 5 for removing bubbles.

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

[0043] Limiting grooves are provided on the front and rear sides of the inner surface of the mounting frame 51, and the pressure plate 59 slides inside the limiting grooves. 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 two sleeve plates 55 are fixedly connected to the radiation heating component 56 on the sides away from each other. Adjusting components 57 are connected to the two sides of the mounting frame 51, and the adjusting components 57 are connected to the arc-shaped pressure plate 512. The lower surface of the scraper 510 is rotatably connected to a roller, and the upper surface of the base 1 is connected to a fixing component 6 for fixing the base.

[0044] When the curved screen and the substrate are pressed and fitted, the curved screen and the substrate are placed on the fixing assembly 6, and the hydraulic push rod 4 is turned on to drive the installation frame 51 to move downward as a whole. During the movement, the bottoms of the pressing plate 59 and the scraper 510 are in contact with the surface of the curved screen in advance, and the installation frame 51 continues to move, so that the second spring 58 and the third spring 511 are compressed to generate elastic force, and the second spring 58 applies elastic force to the curved screen through the pressing plate 59, and the third spring 511 applies force to the curved screen through the moving plate 54 and the scraper 510. The pressing plate 59 presses the middle of the curved screen, and then the servo motor 52 is turned on to drive the first bidirectional threaded rod 53 to rotate, and the first bidirectional threaded rod 53 is driven by the action of the thread The two sleeve plates 55 are moved away from each other, and the sleeve plates 55 drive the scraper plate 510 to slide on the surface of the curved screen through the moving plate 54. The scraper plate 510 moves to both sides, and the scraper plate 510 moves from the middle to both sides, so as to drive the bubbles between the curved screen and the substrate to both sides, so as to discharge the bubbles before pressing, and solve the problem that the bubbles cannot be discharged in the overall pressing of the prior art. The mounting frame 51 continues to move downward for 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 is subjected to a greater extrusion force, and the servo motor 52 drives the first bidirectional threaded rod 53 to rotate forward and reverse, thereby driving the moving plate 54 and the scraper plate 510 to move back and forth on the curved screen for pressing, so as to improve the quality of the bonding.

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

[0046] One side of the internal threaded sleeve 562 is located inside the slide rail 561 and slides, one side of the second bidirectional threaded rod 565 passes through the first through slot 569 and slides with each other, the gear 566 is located inside the rectangular frame 567, the rectangular frame 567 is located in front of the first through slot 569, the upper and lower first racks 568 are arranged in sequence at intervals, 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 on the lamp holder 563 in sequence.

[0047] During the bonding process, temperature is also an important factor affecting the bonding quality between the curved screen and the substrate. When the moving plate 54 drives the scraper 510 to slide the curved screen on the surface, 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 567. When the gear 566 contacts the first rack 568 above, the gear 566 reverses and drives the second bidirectional threaded rod 565 to reverse, thereby driving the two internal threaded sleeves 562 on the surface of the second bidirectional threaded rod 565 away from each other, driving the two groups of radiation lamp groups 564 away from each other, and when the gear 566 leaves the first rack 568 above, the second bidirectional threaded rod 565 is rotated. When the gear 566 contacts the first rack 568 below, the gear 566 rotates forward, driving the two internal threaded sleeves 562 to slide close to each other inside the slide rail 561, so that the second bidirectional threaded rod 565 continuously rotates forward, and when the gear 566 moves to the end of the rectangular frame 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 567, and the gear 566 drives the second bidirectional threaded rod 565 to continuously rotate forward and reverse, and finally the radiation lamp group 564 continuously moves away from and approaches each other, 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 heated evenly, and further improve the adhesion between the curved screen and the substrate.

[0048] like Figure 2 , Figure 6 and Figure 7 As shown, the adjustment component 57 includes a support slide groove 576 opened on the front and rear sides of the installation frame 51, a second rack 571 sliding on both sides of the installation frame 51, and a fixed plate 577 fixed on both sides of the installation frame 51. The fixed plate 577 is internally slidably connected to a telescopic rod 574, the bottom of the telescopic rod 574 is fixedly connected to a third rack 572, the outer surface of the telescopic rod 574 is sleeved with a first spring 575, and the support slide groove 576 is internally slidably connected to a support slide rod 573.

[0049] The bottom of the supporting slide rod 573 is fixedly connected to both sides of the outer surface of the arc pressure 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 pressure plate 512, the third rack 572 is meshed with the second rack 571, and the top and bottom of the first spring 575 are fixedly connected to the fixed plate 577 and the third rack 572 respectively.

[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, thereby releasing the fixing effect of the second rack 571, thereby pulling the second rack 571 to drive the arc-shaped pressing plate 512 to move, so that the distance between the two arc-shaped pressing plates 512 is consistent with the width of the curved screen to be pressed, so that the arc edge of the curved screen can be effectively pressed, thereby effectively improving the practicability of the laminating machine.

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

[0052] The fixing component includes a fixing frame 64 fixed at the middle of the upper surface of the base 1 and two second thorn racks 613 fixed at the middle of the lower surface of the placing plate 63, the first thorn racks 611 are slidably connected to both sides of the fixing frame 64, two fourth springs 612 are fixedly connected to one side of the two first thorn racks 611 close to each other, and the second thorn racks 613 are meshed with the first thorn racks 611.

[0053] When the curved screen is bonded, the traditional method of clamping the curved screen is to rotate the threaded rod to clamp the two sides of the curved screen. This clamping method is time-consuming and excessive force may cause cracks on the sides of the curved screen.

[0054] The curved screen is placed on the processed area of ​​the placement plate 63, and the placement plate 63 is pressed downward as a whole, driving 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 slide plate 68 to move downward, and the slide plate 68 drives one end of the hinged rod 610 to move downward, so that one end of the hinged rod 610 pushes the slide plate 68 to move under the placement plate 63, and the two slide plates 68 approach each other, respectively driving the two clamping plates 67 to move inside the second through groove 66, and approaching and clamping the curved screen. At this time, the placement plate 63 cannot continue to move, and the second thorn rack 613 is engaged with the first thorn rack 611, so that the second thorn rack 613 cannot move upward, so that the placement plate 63 is fixed, and the curved screen is also fixed, and the curved screen is clamped quickly, thereby saving a lot of clamping time and improving work efficiency.

[0055] like Figure 6 and Figure 8 As shown, the limiting assembly 69 includes limiting grooves 691 opened on both sides of the upper surface of the placing plate 63, the limiting grooves 691 are internally slidably connected to the limiting plates 692, the two limiting plates 692 are fixedly connected to the side away from each other with a connecting rod 694, the outer side of the connecting rod 694 is slidably connected to a connecting rail 693, and the top of the connecting rail 693 is fixedly connected to the other side of the lower surface of the second rack 571.

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

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

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

[0059] Instructions for use: First, by pushing the scraper 510 on the exhaust assembly 5 to move from the middle to both sides on the curved screen, the bubbles between the curved screen and the substrate can be effectively driven out. At the same time, the scraper 510 will continuously move back and forth on the curved screen, which can effectively fit the curved screen. Under the irradiation of the radiation lamp group 564, the curved screen can be quickly and comprehensively heated to further improve the fit between the curved screen and the substrate. The distance between the two arc-shaped pressing plates 512 can be effectively adjusted by adjusting the assembly 57, so that the arc-shaped pressing plates 512 can press the arc edges of curved screens of different widths, thereby ensuring the fit of the curved screen and the practicality of the laminating machine.

[0060] The placement plate 63 can be pressed downward by the fixing component 6, and the front and rear sides of the curved screen can be quickly pressed, thereby reducing the time for fixing the curved screen. The placement plate 63 is effectively fixed by the mutual engagement between the first thorn rack 611 and the second thorn rack 613, and is limited by the two limiting plates 692 of the limiting component 69, so that the curved screen is more stable when fitted, and the processing accuracy is higher, and the processing quality is further improved.

[0061] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
