Description

Technical Field

[0001] The utility model relates to the technical field of curved surface multi-screen lamination, in particular to a curved surface multi-screen lamination jig. Background Art

[0002] As a special computer peripheral, the touch screen is currently the simplest, most convenient and natural way of human-computer interaction. It gives multimedia a brand new look and is an extremely attractive new multimedia interactive device. Currently, touch screens are widely used in mobile phones, computers, car central control and industrial control displays, and full bonding technology is becoming more and more prominent. Among them, the full bonding of curved multi-screens has become a difficult point.

[0003] At present, there are two ways to bond multiple screens. The first way is to bond multiple LCD panels or LCD modules at a time. The equipment needs multi-axis linkage, the equipment cost is very high, and it has high dependence on equipment and engineering technicians. The second way is to bond one LCD panel or LCD module at a time. This method is less efficient because the glue is applied once and cured once, and the cumulative production time is longer. In the face of the bonding of curved multi-screen cover plates, the above two methods have certain difficulties. For this reason, we propose a curved multi-screen bonding fixture.

[0004] An existing patent (publication number: CN218383543U) discloses a curved multi-screen laminating jig, including a laminating jig transfer plate and a laminating jig upper mold, wherein a middle laminating jig lower mold is bolted to the top outer wall of the laminating jig transfer plate near the middle position, a stainless steel mini cylinder 1 is installed near one side of the top outer wall of the laminating jig transfer plate, a stainless steel mini cylinder 2 is installed near the other side of the top outer wall of the laminating jig transfer plate, a left laminating jig lower mold is installed at one end of the stainless steel mini cylinder 1 away from the laminating jig transfer plate, and a right laminating mold is installed at one end of the stainless steel mini cylinder 2 away from the laminating jig transfer plate. By laminating multiple liquid crystal panels or liquid crystal modules at one time, production efficiency is improved, equipment research and development difficulty and equipment cost investment are reduced, and requirements for engineering and technical personnel are reduced.

[0005] However, the above technical solution still has certain defects. In the above technical solution, when the liquid crystal surface is fixed, the fixed position is a fixed setting and cannot be adjusted. As a result, when fixing LCD panels of different sizes, if the position of the limit module needs to be changed, the limit block needs to be removed by removing the bolts, and then the limit module is fixed to another place by bolts. As a result, a lot of time needs to be spent on debugging the jig during the production process, affecting production efficiency. For this reason, a curved multi-screen bonding jig is proposed.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0028] The following describes an embodiment of the utility model based on its overall structure.

[0029] Curved multi-screen lamination fixture, such as Figures 1 to 4 As shown, it comprises a base 1, and two sets of lower templates 2 are hinged on the top of the base 1;

[0030] The base 1 comprises a bottom plate 101, a plurality of pads 102 are fixedly connected to the top of the bottom plate 101, and two groups of hydraulic rods 103 are hinged to the top of the base 1;

[0031] The lower template 2 includes two groups of flaps 201, which are hinged at the top of the bottom plate 101, and the top of the hydraulic rod 103 is hinged at the bottom of the flap 201. The inner wall of the flap 201 is rotatably connected to multiple groups of bidirectional threaded rods 202 extending to the outside of the flap 201. The outer wall of each group of bidirectional threaded rods 202 is threadedly connected to two groups of sliders 203, and the side walls of the sliders 203 are fixedly connected to protective pads 204. The threads of the bidirectional threaded rods 202 at the contact positions with the two groups of sliders 203 are arranged in opposite directions.

[0032] By placing multiple groups of LCD panels on the top of two groups of flip plates 201 and the bottom plate 101 respectively, and then rotating multiple groups of bidirectional threaded rods 202 to make the slider 203 approach the LCD panel, the LCD panel will not be displaced during the production process, and then the hydraulic rod 103 is used to push the flip plate 201 to flip to the specified angle, thereby completing the fixed placement of the LCD panel.

[0033] Please refer to the figure in particular. The top of the base 1 is provided with an upper template 3 located above the lower template 2. The upper template 3 includes two groups of guide columns 301. The outer walls of the two groups of guide columns 301 are respectively slidably sleeved with a group of collars 302. The side walls of the two groups of collars 302 are fixedly connected with an upper pressing plate 303. The side walls of the upper pressing plate 303 are hinged with two groups of side pressing plates 304, and the two groups of side pressing plates 304 are respectively located on both sides of the upper pressing plate 303. The top of the upper pressing plate 303 is slidably connected with two groups of connecting plates 305. The top of each group of connecting plates 305 is respectively hinged with a group of ejector rods 306. The ends of each group of ejector rods 306 are respectively hinged. The two connecting plates 305 are respectively hinged at the top end of a group of side pressure plates 304, a support spring 307 is fixedly connected between the two groups of connecting plates 305, the side wall of the base 1 is fixedly connected with a guide rail 308, the outer wall of the guide rail 308 is slidably connected with two groups of sliding frames 309, the inner wall of each group of sliding frames 309 is respectively slidably sleeved with a group of first sliding rods 310, the end of each group of first sliding rods 310 is respectively fixedly connected to the side wall of a group of side pressure plates 304, the inner wall of each group of sliding frames 309 is respectively slidably connected with a group of second sliding rods 311, and the end of each group of second sliding rods 311 is respectively fixedly connected to the side wall of a group of flaps 201.

[0034] When the flap 201 is pushed by the hydraulic rod 103 to flip, the flap 201 drives the second sliding bar 311 to flip, so that the second sliding bar 311 pushes the sliding frame 309 to move. The sliding frame 309 pushes the first sliding bar 310 during the movement, thereby driving the side pressure plate 304 to flip through the first sliding bar 310, so that the overall angle of the side pressure plate 304 and the flap 201 is always consistent. During the production process, the upper pressure plate 303 is replaced according to the curvature of different liquid crystal panels to meet the use requirements of panels with different curvatures. During the flipping of the side pressure plate 304, the side pressure plate 304 pushes the connecting plate 305 to slide through the push rod 306, so that the two groups of connecting plates 305 are close to each other to compress the support spring 307, thereby utilizing the resilience of the support spring 307 to be transmitted to the side pressure plate 304 through the push rod 306, and then transmitted from the side pressure plate 304 to The first slide bar 310 is transferred to the sliding frame 309, and then transferred to the second slide bar 311 through the sliding frame 309, so that the first slide bar 310 and the second slide bar 311 are tightly fitted to the inner wall of the sliding frame 309, thereby reducing the influence of the gap between the first slide bar 310 and the second slide bar 311 and the sliding frame 309 on the angle of the flap 201 and the side pressure plate 304. When the screen is bonded, the upper pressure plate 303 is pushed downward so that the upper pressure plate 303 drives the side pressure plate 304 to slide downward, so that the panel is bonded. Since the angle of the flap 201 is controlled by the hydraulic rod 103, when the angle of the flap 201 remains unchanged, the sliding frame 309 cannot slide, so the side pressure plate 304 drives the first slide bar 310 to support parallel downward sliding, and the angle of the side pressure plate 304 does not change during the sliding process.

[0035] When in use, multiple groups of bidirectional threaded rods 202 are arranged inside the flap 201, and the bidirectional threaded rods 202 are rotated during use to change the interval between the sliders 203, so that when processing screens of different sizes, adjustments can be made more conveniently and efficiently, thereby improving the efficiency of fixture debugging and installation and accelerating production speed. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
