Description

Technical Field

[0001] The present invention relates to the technical field related to laminating machines, and in particular to a fine-tuning device for a laminating machine. Background Art

[0002] In the processing of touch screens, the touch screen film is generally bonded to the substrate through a bonding machine. The bonding machine can drive the film material to move down and cover the substrate to complete the bonding action, and the lifting and lowering adjustment of the bonding machine is generally completed by a cylinder.

[0003] For example, the Chinese patent publication number "CN214606440U" proposes a touch screen production laminating machine with a fine-tuning slide. By adjusting the rotating motor, telescopic rod and vacuum pump, the substrate and touch screen film can be successively adsorbed and moved to the base through the suction cup, and then the adjusting cylinder is used to drive the pressing plate to move down to directly press the touch screen film down and fit it on the substrate. This device still has certain defects in actual use: because the area of ​​the telescopic part of the adjusting cylinder is much smaller than the area of ​​the pressing plate, the pressure applied by the adjusting cylinder to the pressing plate is concentrated in the central area of ​​the pressing plate, which inevitably leads to uneven pressure on the substrate by the pressing plate. Especially for substrates with larger areas, the peripheral areas around the substrate are less pressurized, which easily causes gaps between the touch screen film and the substrate and generates bubbles, greatly reducing the quality of lamination. Accordingly, this application proposes a laminating machine fine-tuning device. Summary of the invention

The lower end of the square nut is fixedly connected to a transverse plate, and the lower end of the transverse plate is fixedly installed with a first telescopic cylinder, and the telescopic end of the first telescopic cylinder is fixedly connected to the material picking tray.

[0010] Preferably, the lower end of the transverse plate is also fixedly connected to a second telescopic cylinder, and the telescopic end of the second telescopic cylinder is fixedly connected to the upper end of the pressing table.

[0013] Preferably, two guide grooves are provided at the upper end of the pressing table, guide rods are slidably connected in the guide grooves, and the lower ends of the guide rods are fixedly connected to the upper end of the shovel plate.

[0019] 2. By setting the transmission assembly and the shovel plate, the rotation of the hollow pressing cylinder can be converted into the forward and backward reciprocating movement of the shovel plate during the rolling and laminating process of the hollow pressing cylinder. In this way, during the rolling process of the hollow pressing cylinder, the shovel plate can be continuously moved to push and scrape the substrate in advance, and the bubbles between the touch screen film and the substrate can be scraped off, so that the touch screen film can be better laminated with the substrate during the subsequent rolling process;

[0020] 3. By setting up the annular air groove, the adjusting air cylinder, the sliding plug, the adjusting screw and the air guide tube and other components, the sliding plug can be driven to move by turning the adjusting screw, so that the air in the adjusting air cylinder can be blown into the annular air groove, and the air pressure in the annular air groove can be adjusted in real time. In this way, the pressure of the hollow pressing cylinder on the substrate can be fine-tuned in real time according to the actual situation to ensure that the touch screen film is perfectly attached to the substrate without damaging the substrate;

[0021] 4. By setting up a bearing platform, the lower side of the conveyor belt can be supported. When the hollow pressing cylinder rolls and bonds the touch screen film, the bearing platform provides a stable supporting effect to ensure that the substrate is in a stable horizontal state, thereby ensuring the bonding quality;

[0022] 5. By setting the guide groove and the guide rod, the shovel plate can be limited so that the shovel plate can only move back and forth in a straight line in the horizontal direction. This ensures that the substrate and the touch screen film will not be damaged, and the gaps and bubbles between the substrate and the touch screen film can be effectively removed.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-Figure 7 A laminating machine fine-tuning device comprises a machine platform 1, a servo motor 2 is fixedly mounted on the upper end of the machine platform 1, a material taking arm 3 is fixedly connected to the output shaft of the servo motor 2, two brackets 5 are fixedly connected to the upper end of the machine platform 1, and a feeding component for conveying substrate materials is arranged between the two brackets;

[0033] The feeding assembly includes two conveying rollers 13 and a conveying belt 14. The conveying rollers 13 are rotatably connected between the two brackets 5, and the two conveying rollers 13 are connected together through the conveying belt 14. The conveying rollers 13 can drive the conveying belt 14 to run and transport the substrate material.

[0034] The lower end of the material taking arm 3 is equipped with an adsorption component and a flattening component, wherein the adsorption component is used to take and place the film material to be bonded, and the flattening component is used to flatten the film and bond it on the substrate.

[0035] Reference Figure 4The flattening assembly includes a press table 12, a baffle 21, a hollow press cylinder 18, and a shovel plate 19. The baffle 21 is fixedly connected to the lower end of the press table 12, and the hollow press cylinder 18 is rotatably arranged on the side wall of the baffle 21. The hollow press cylinder 18 is connected to the shovel plate 19 through a transmission assembly. It should be noted that the hollow press cylinder 18 can rotate freely. When the press table 12 moves downward, the cylinder surface of the hollow press cylinder 18 can contact the substrate. When the press table 12 moves horizontally, the hollow press cylinder 18 in contact with the substrate will roll accordingly, thereby rolling and pressing the touch screen film onto the substrate to ensure uniform pressure on all parts of the substrate and avoid the generation of gap bubbles. It is worth mentioning that since the hollow press cylinder 18 rolls on the substrate in the horizontal direction, the bubbles between the touch screen film and the substrate can also be rolled out.

[0036] Reference Figure 1 and Figure 7 A bearing platform 7 is provided between the two brackets 5, and the left and right side walls of the bearing platform 7 are respectively fixedly connected to the two brackets 5. By providing the bearing platform 7, the lower side of the conveyor belt 14 can be supported, and the bearing platform 7 can provide a stable supporting effect during the process of the hollow pressing cylinder 18 rolling and laminating the touch screen film, ensuring that the substrate is in a stable horizontal state, thereby ensuring the lamination quality;

[0037] The transmission assembly includes a driving arm 27, a pushing arm 30 and a connecting rod 23. A hollow shaft 26 is rotatably connected to the side plate of the baffle 21. The hollow shaft 26 is fixedly connected to the axial center of the hollow pressing barrel 18. The driving arm 27 is fixedly connected to the side wall of the hollow shaft 26. One end of the pushing arm 30 is rotatably connected to the connecting rod 23, and the other end of the pushing arm 30 is rotatably connected to the driving arm 27. The end of the connecting rod 23 away from the pushing arm 30 is fixedly connected to the side wall of the shovel plate 19. It should be noted that by setting up the transmission assembly, the rotation of the hollow pressing barrel 18 can be converted into a horizontal linear motion of the shovel plate 19. In this way, before the hollow pressing barrel 18 rolls the touch screen film, the shovel plate 19 can be continuously moved to push and scrape the substrate in advance, which can scrape off the bubbles between the touch screen film and the substrate, so that in the subsequent rolling process, the touch screen film can be better bonded to the substrate.

[0038] Reference Figure 4The upper end of the press table 12 is provided with two guide grooves 22, in which a guide rod 24 is slidably connected, and the lower end of the guide rod 24 is fixedly connected to the upper end of the shovel plate 19. A limit plate 25 is fixedly connected to the side wall of the guide rod 24, and the limit plate 25 is slidably arranged on the upper end surface of the press table 12. Specifically, by setting the guide grooves 22 and the guide rods 24, the shovel plate 19 can be limited so that the shovel plate 19 can only move in the horizontal direction. In addition, by setting the limit plate 25, the guide rod 24 can be prevented from being separated from the guide grooves 22. Furthermore, a limit plate 25 can also be arranged on the lower end surface of the press table 12, so that the shovel plate 19 can be further limited in the vertical direction to avoid vertical jumping due to vibration, and ensure that the shovel plate 19 is always in contact with the upper end surface of the substrate to ensure the effect of removing bubbles in the gaps.

[0039] The adsorption component includes a material picking tray 4 and a plurality of suction cups 15, and the plurality of suction cups 15 are fixedly mounted at the lower end of the material picking tray 4. It should be noted that a vacuum pump can be installed on the material picking tray 4, and the vacuum pump is used to extract or supply air into the suction cups 15 so that the suction cups 15 can adsorb the touch screen film or separate the suction cups 15 from the touch screen film. The installation of the vacuum pump and the connection method of the suction cups 15 can refer to the touch screen production laminating machine with a fine-tuning slide table proposed in the patent publication number "CN214606440U" mentioned in the background technology of this article. Since this is an existing mature technology and has nothing to do with the design purpose of this scheme, it will not be elaborated here.

[0040] Reference Figure 3 The lower end of the material taking arm 3 is provided with a strip groove 16, and a transverse screw 17 is rotatably connected to the inner wall of the strip groove 16, and a square nut 20 is threadedly connected to the transverse screw 17, and the square nut 20 is slidably arranged in the strip groove 16, and a transverse plate 9 is fixedly connected to the lower end of the square nut 20, and a first telescopic cylinder 10 is fixedly installed at the lower end of the transverse plate 9, and the telescopic end of the first telescopic cylinder 10 is fixedly connected to the material taking tray 4. A first drive motor 6 is fixedly installed on the side wall of the bracket 5, and the output shaft of the first drive motor 6 is fixedly connected to the conveying roller 13, and a second drive motor 8 is fixedly connected to the side wall of the material taking arm 3, and the output shaft of the second drive motor 8 is fixedly connected to the transverse screw 17.

[0041] It should be noted that the square nut 20 has a square structure in appearance, and the side walls of the square nut are fitted together with the inner walls of the strip groove 16, so that the inner walls of the strip groove 16 can be used to limit the square nut 20. When the second drive motor 8 drives the transverse screw 17 to rotate, the square nut 20 can only move along the direction of the strip groove 16 under the action of the threaded transmission. Furthermore, the second drive motor 8 is also a servo drive motor, which can control its rotation direction, so that it can drive the transverse screw 17 to rotate forward or reverse, thereby causing the square nut 20 to move to the left or right, and then drive the adsorption assembly and flattening assembly below to move to the specified position through the transverse plate 9.

[0042] The lower end of the transverse moving plate 9 is also fixedly connected to a second telescopic cylinder 11 , and the telescopic end of the second telescopic cylinder 11 is fixedly connected to the upper end of the pressing table 12 .

[0043] Reference Figure 6 The side wall of the hollow press cylinder 18 is provided with an annular air groove 29, an adjusting air cylinder 31 is fixedly connected to the inner wall of the hollow press cylinder 18, and an air guide tube 33 connected to the inner box of the adjusting air cylinder 31 is fixedly connected to the side wall of the adjusting air cylinder 31, and the end of the air guide tube 33 away from the adjusting air cylinder 31 is connected to the annular air groove 29, and a sliding plug 32 is sealingly and slidingly connected in the adjusting air cylinder 31, and an adjusting screw 28 is rotatably connected to the side wall of the sliding plug 32, and the adjusting screw 28 is threadedly connected to the adjusting air cylinder 31, and the end of the adjusting screw 28 away from the sliding plug 32 extends to the outside of the hollow press cylinder 18. Specifically, as Figure 6 As shown, the adjusting screw 28 is threadedly connected to the right end of the adjusting cylinder 31. By twisting the adjusting screw 28, the adjusting screw 28 can be screwed in or out of the adjusting cylinder 31 to drive the sliding plug 32 to move left or right. In this way, the air in the adjusting cylinder 31 can be blown into the annular air groove 29, and the air pressure in the annular air groove 29 can be adjusted in real time. In this way, the pressure of the hollow pressing cylinder 18 on the substrate can be fine-tuned in real time according to the actual situation to ensure that the touch screen film fits perfectly on the substrate without damaging the substrate;

[0044] In the present invention, the servo motor 2 drives the picking arm 3 to rotate, so that the picking arm 3 can conveniently drive the picking tray 4 to rotate to the storage place of the touch screen film material, and the touch screen film can be adsorbed by the suction cup 15. Then the servo motor 2 drives the picking arm 3 to rotate again, and makes the picking arm 3 rotate to the side of the conveyor belt 14. Then the first drive motor 6 starts and drives the conveyor roller 13 fixedly connected to it to rotate, so that the conveyor belt 14 runs, and a substrate to be bonded can be transported to the top of the supporting platform 7.

[0045] Then the first telescopic cylinder 10 pushes the material picking tray 4 downward, and the suction cups 15 under the material picking tray 4 can drive the touch screen film downward together, and finally the touch screen film can be preliminarily attached to the top of the substrate. Then the negative pressure state of the suction cup 15 can be released by a vacuum pump or other equipment, so that the suction cup 15 is separated from the touch screen film. After the separation is completed, the first telescopic cylinder 10 drives the material picking tray 4 upward, so that the suction cup 15 is away from the touch screen film and the substrate. Then the second telescopic cylinder 11 drives the pressing table 12 downward, and until the hollow pressing cylinder 18 under the pressing table 12 moves to the upper end surface of the substrate, the second telescopic cylinder 11 stops moving, and then the second drive motor 8 drives the transverse screw 17 to rotate, so that the square nut 20 can move along the direction of the strip groove 16, and the square nut 20 can drive the transverse plate 9 to move along the direction of the strip groove 16, refer to Figure 1 In the direction shown, the transverse plate 9 drives the pressing table 12 to move to the right through the second telescopic cylinder 11 (because the material picking tray 4 is connected to the transverse plate 9 by the first telescopic cylinder 10, the material picking tray 4 also moves synchronously, so the pressing table 12 will not interfere with the material picking tray 4).

[0046] When the pressing table 12 moves to the right above the substrate, the hollow pressing cylinder 18 contacts the upper end surface of the substrate, so that the hollow pressing cylinder 18 can rotate while the pressing table 12 is moving. During the rotation of the hollow pressing cylinder 18, the touch screen film on the substrate can be rolled and pressed onto the substrate. Compared with the method of pushing the pressure plate downward by the cylinder, the rolling and pressing method of the hollow pressing cylinder 18 can apply pressure to the substrate more evenly, thereby avoiding gaps and bubbles caused by uneven pressure. In addition, it is worth mentioning that when the hollow pressing cylinder 18 rotates, it will also drive the hollow shaft 26 coaxially connected to it to rotate. Figure 5 As shown, when the hollow shaft 26 rotates, it will drive the driving arm 27 to rotate together. While the driving arm 27 rotates around the axis of the hollow shaft 26, it will also drive the pushing arm 30 to move back and forth in all directions, and finally push the connecting rod 23 to move back and forth horizontally (the connecting rod 23 is affected by the limiting effect of the guide groove 22 and the guide rod 24 and can only move in the horizontal direction). Specifically, the driving arm 27 and the pushing arm 30 can form a structure similar to a "crank connecting rod", which can convert the rotation of the rotating axis of the hollow shaft 26 into the reciprocating movement of the connecting rod 23.

[0047] When the connecting rod 23 moves back and forth in the horizontal direction, it can push the scraper plate 19 to move back and forth synchronously. In this way, while the hollow pressing cylinder 18 rolls the touch screen film on the substrate, the scraper plate 19 moves back and forth on the upper side of the substrate, and can scrape and remove the gaps and bubbles between the touch screen film and the substrate in advance, so that in the subsequent rolling process, the touch screen film can be better bonded to the substrate.

[0048] Further, such as Figure 6As shown, the hollow pressing cylinder 18 is provided with an annular air groove 29 in the circumference, and the slide plug 32 can be pushed to move in the adjusting air cylinder 31 by turning the adjusting screw 28. Specifically, since the adjusting screw 28 is threadedly connected to the right end of the adjusting air cylinder 31, when the adjusting screw 28 is turned, the adjusting screw 28 can move horizontally under the action of the thread transmission, and the adjusting screw 28 can drive the slide plug 32 to move left and right. When the slide plug 32 is driven to move left, the air on the right side of the slide plug 32 can be blown into the annular air groove 29 through the air guide pipe 33 to increase the air pressure in the annular air groove 29; and when the slide plug 32 moves right, the air in the annular air groove 29 can be pumped into the adjusting air cylinder 31 to reduce the air pressure in the annular air groove 29. In this way, the annular air groove 29 can be adjusted by turning the adjusting screw 28. The air pressure in the air groove 29 can adjust the pressure of the hollow pressing cylinder 18 on the substrate according to the actual fitting situation, so as to achieve slight adjustment of the pressure on the substrate to ensure that the touch screen film is perfectly fitted on the substrate without damaging the substrate. In addition, by setting the annular air groove 29, the pressure on the substrate can be adjusted by adjusting the air pressure in the annular air groove 29, which has the following benefits: since the air is always evenly distributed in the annular air groove 29, although the air pressure in the annular air groove 29 is adjusted and changed, the pressure applied by the air to the inner wall of the annular air groove 29 is always constant, so that the pressure applied by the hollow pressing cylinder 18 on the substrate at various locations can be uniform, which can not only make the touch screen film fit perfectly on the substrate, but also prevent gaps caused by uneven pressure.

[0049] The above description is only a preferred specific implementation manner of the present invention, but 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 scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
