Description

Technical Field

[0001] The utility model relates to the technical field of touch screen installation, in particular to a fixture for aligning and gluing a liquid crystal screen and a touch screen. Background Art

[0002] There are two main methods for aligning and gluing the touch screen and the LCD screen: frame gluing and full gluing. Frame gluing is to use double-sided tape to glue the touch screen and the LCD screen together. It is simple to operate and low in cost, but it is easy for dust, moisture and other impurities to enter, affecting the display effect. Full gluing uses OCA optical glue or water glue to seamlessly glue the two together. Although the process is complicated and the cost is high, it can significantly improve the visual effect and user experience.

[0003] In the prior art, a fixture for aligning and gluing a liquid crystal screen and a touch screen is proposed in the publication number CN220641698U, which includes a workbench, two side panels are fixedly installed on the top of the workbench, a top panel is fixedly installed on the top of the two side panels, a motor is fixedly installed on the left side of the left side panel, a screw rod is fixedly installed on the output end of the motor and is rotatably connected to the left side of the right side panel, a moving block is threadedly installed on the surface of the screw rod, a slider extending to the inside of the top panel is fixedly installed on the top of the moving block, a hydraulic rod is fixedly installed on the bottom of the moving block, a mounting plate is fixedly installed on the output end of the hydraulic rod, a first loading mold is fixedly installed on the bottom of the mounting plate, and a vacuum pump is fixedly installed on the top of the mounting plate. The fixture for aligning and gluing a liquid crystal screen and a touch screen will facilitate the alignment of the first loading mold and the second loading mold, save time and labor, and does not require manual operation by the staff, thereby greatly improving the practicality of the device.

[0004] When this application is used, the LCD screen is placed in the second loading mold and the touch screen is placed in the first loading mold, and then installed. However, when placing the LCD screen, the LCD screen will be manually placed in the second loading mold. At this time, it is easy for the LCD screen to get stuck in the second loading mold due to tilt. When the touch screen is adsorbed by the vacuum pump, its adsorbed position is not in the center. At this time, the non-adsorbed position is prone to tilt, thereby affecting the gluing work between the LCD screen and the touch screen. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a fixture for aligning and gluing a liquid crystal screen and a touch screen, so as to solve the technical problems mentioned in the above background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A jig for aligning and gluing a liquid crystal screen and a touch screen comprises a jig base and a bracket, wherein a groove is provided on the top side of the jig base, a number of sliding rollers are rotatably connected in the groove, a rotating hole is provided on both sides of the top of the jig base, a first positioning piece is provided in the rotating hole, a second positioning piece is provided on the end side of the groove, an electric telescopic joint is fixedly installed on the top side of the bracket, the bottom end of the electric telescopic joint passes through the top side of the bracket and is connected to an upper loading mold, a loading piece is provided in the upper loading mold.

[0010] In a preferred example, the utility model can be further configured as follows: the second positioning member includes two supporting shafts, the top ends of the two supporting shafts are rotatably connected to positioning plates, the outer peripheral walls of the positioning plates are tangent to the sides of the grooves, and the sides of the supporting shafts are fixedly connected to contact plates.

[0011] In a preferred example, the utility model can be further configured as follows: the loading part includes a vacuum pump, the vacuum pump is fixedly installed on the top side of the upper loading mold, a ventilation pipe is fixedly connected to the top side wall of the upper loading mold, both ends of the ventilation pipe are connected to suction pipes, the bottom end of the suction pipe extends into the upper loading mold, and the suction pipe close to the vacuum pump is connected to the output end of the vacuum pump.

[0012] In a preferred example, the utility model can be further configured as follows: two ends of the top side wall of the upper loading mold are rotatably connected to two pulleys, and one end of the upper loading mold is opened.

[0013] In summary, the utility model includes at least one of the following beneficial technical effects:

[0014] 1. The fixture for aligning and gluing the LCD screen and the touch screen can quickly place the touch screen and the LCD screen on the groove and in the upper loading mold when placing the touch screen and the LCD screen. By using the first positioning member, the second positioning member and the loading member, the LCD screen and the touch screen can be prevented from tilting and shifting sideways when placed, and the LCD screen can be prevented from being stuck due to tilting, thereby improving the stability, gluing quality and work efficiency of the LCD screen and the touch screen when aligning and gluing.

[0015] 2. In the fixture for aligning and gluing the LCD screen and the touch screen, after the end of the LCD screen is attached to the second positioning piece, the bottom end of the tension spring is pulled downward, thereby increasing the friction between the bottom side of the turntable and the top side of the fixture base, thereby preventing the LCD screen from moving back. In addition, the outer peripheral wall of the turntable needs to be provided with anti-slip grooves, thereby preventing the LCD screen from moving back after the turntable is positioned, thereby improving the stability of the LCD screen when positioning;

[0016] 3. The fixture for aligning and gluing the LCD screen and the touch screen starts the vacuum pump to make it suck air, and then cooperates with the suction pipe and the ventilation pipe to make the bottom ends of the two suction pipes suck air. When the bottom ends of the two suction pipes are sucking air, the two ends of the top side of the touch screen will be adsorbed, and the two suction pipes are located in the middle of the end side of the upper loading mold. Therefore, when adsorbing the touch screen, the middle parts of the two end sides of the touch screen will be adsorbed, which can be more stable and avoid the phenomenon of offset, thereby achieving the positioning of the touch screen to improve stability and improve the gluing quality during alignment and gluing.

DETAILED DESCRIPTION

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings. Example

[0025] Reference Figure 1-Figure 5 The utility model discloses a fixture for aligning and gluing a liquid crystal screen and a touch screen, comprising a fixture base 1 and a bracket 2. A groove 3 is provided on the top side of the fixture base 1, and a number of sliding rollers 4 are rotatably connected in the groove 3. The top of the fixture base 1 is provided with rotating holes 5 on both sides of the groove 3, and a first positioning member 6 is arranged in the rotating hole 5. A second positioning member 7 is arranged on the end side of the groove 3. An electric telescopic joint 8 is fixedly installed on the top side of the bracket 2, and the bottom end of the electric telescopic joint 8 passes through the top side of the bracket 2 and is connected to an upper loading mold 9, and a loading member 10 is arranged in the upper loading mold 9.

[0026] In this embodiment, when in use, the LCD screen is placed on the end of the groove 3 away from the second positioning member 7, and the bottom side of the LCD screen is in contact with the sliding roller 4, and then pushed in the direction of the second positioning member 7. When pushing the second positioning member 7, the first positioning member 6 provided at this time will assist the movement of the LCD screen to prevent the LCD screen from lateral deviation during the movement process, thereby improving the stability of the LCD screen when placed, until the end of the LCD screen is in contact with the second positioning member 7 and then stopped, and fixed by the first positioning member 6 to prevent the LCD screen from moving back. Then, the touch screen is placed in the upper loading mold 9, wherein the touch screen is adsorbed by the provided loading member 10, and the top sides of both ends of the touch screen are adsorbed during adsorption to prevent tilting and affect the gluing work;

[0027] At this time, apply the glue specially used for gluing to the appropriate position on the bottom side of the touch screen or the top side of the LCD screen, and then start the electric telescopic joint 8, so that the electric telescopic joint 8 drives the upper loading mold 9 to move downward, and then the upper loading mold 9 will move downward, and at the same time, it will drive the loaded touch screen to move downward, so that the touch screen and the LCD screen can be aligned and glued. After the gluing is completed, the adsorption of the touch screen is released by the loading part 10, and then the upper loading mold 9 is driven upward by the electric telescopic joint 8 to restore the upper loading mold 9 to its original position, and then the fixation of the first positioning part 6 is released, and then the screen with glue is directly slid and pulled out in the direction away from the second positioning part 7, so as to achieve the effect of avoiding tilting when positioning the touch screen and avoiding the LCD screen from being stuck due to tilted placement and being inconvenient to take out, thereby improving the stability of the touch screen and the LCD screen when gluing, and ensuring the gluing quality of the alignment and gluing.

[0028] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the first positioning member 6 includes a rotating disk 11 , which is rotatably mounted on the top side of the rotating hole 5 , and a tension spring 12 is fixedly connected to the middle part of the bottom side of the rotating disk 11 .

[0029] In this embodiment, the set turntable 11 can rotate on the top side of the rotating hole 5. When the LCD screen slides on the sliding roller 4, the sliding roller 4 is used to prevent the bottom side of the LCD screen from being damaged by friction. The set turntable 11 is used to position the LCD screen and adjust the moving direction when it moves, so as to prevent the moving direction of the LCD screen from shifting and causing deviation in the gluing work, thereby affecting the quality of the gluing. The set tension spring 12, after the end of the LCD screen is attached to the second positioning member 7, the bottom end of the tension spring 12 is pulled downward, thereby increasing the friction between the bottom side of the turntable 11 and the top side of the fixture base 1, thereby preventing the LCD screen from moving back. In addition, the outer peripheral wall of the set turntable 11 needs to be provided with anti-slip grooves, so as to prevent the LCD screen from moving back after the turntable 11 is positioned, thereby improving the stability of the LCD screen when positioning.

[0030] In a further preferred embodiment of the present invention, Figure 1-4 As shown, an electromagnet 13 is fixedly connected to the bottom end of the rotating hole 5, and a gap is left between the top end of the electromagnet 13 and the bottom end of the tension spring 12.

[0031] In this embodiment, after the LCD screen moves to the second positioning member 7, the electromagnet 13 is energized and the electromagnet 13 will absorb the stretch spring 12, which will then stretch. The closer the stretch spring 12 is to the electromagnet 13, the stronger the magnetism it receives, so the stretch spring 12 can be stretched. After the stretch spring 12 is stretched, the downward force of the turntable 11 is increased, thereby increasing the friction between the bottom side of the turntable 11 and the top side of the fixture base 1, thereby preventing the turntable 11 from rotating and causing the LCD screen to move back. In addition, a gap is left between the bottom of the stretch spring 12 and the top of the electromagnet 13 to provide sufficient space for the stretching of the stretch spring 12.

[0032] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the second positioning member 7 includes two support shafts 14 , the top ends of the two support shafts 14 are rotatably connected to positioning plates 15 , the outer peripheral walls of the positioning plates 15 are tangent to the sides of the groove 3 , and the sides of the support shafts 14 are fixedly connected to a contact plate 20 .

[0033] In this embodiment, the two support shafts 14 are provided to cooperate with the positioning plate 15. When the LCD screen continues to move toward the contact plate 20, the portion of the LCD screen close to the contact plate 20 gradually increases with the axis of the turntable 11 as a reference. At this time, the portion that is not positioned will increase, which may easily lead to the risk of lateral deviation. Therefore, the LCD screen is pushed between the two positioning plates 15, so that both ends of the LCD screen are positioned to avoid deviation. The contact plate 20 is L-shaped. The LCD screen is continuously pushed until the end contacts the contact plate 20 to complete the placement and positioning. The outer peripheral wall of the positioning plate 15 is tangent to the side of the groove 3, which is convenient for fitting and positioning the side of the LCD screen.

[0034] In this embodiment, it should be noted that the thickness of the turntable 11 is smaller than the thickness of the liquid crystal screen, and the thickness of the positioning plate 15 is smaller than the thickness of the liquid crystal screen.

[0035] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the loading part 10 includes a vacuum pump 16, and the vacuum pump 16 is fixedly installed on the top side of the upper loading mold 9. A ventilation pipe 17 is fixedly connected to the top side wall of the upper loading mold 9. Both ends of the ventilation pipe 17 are connected to an air suction pipe 18. The bottom end of the air suction pipe 18 extends into the upper loading mold 9. The air suction pipe 18 close to the vacuum pump 16 is connected to the output end of the vacuum pump 16.

[0036] In this embodiment, the touch screen is pushed inward from the end of the upper loading mold 9 until the end of the touch screen is in contact with the inner end side wall of the upper loading mold 9, and then the vacuum pump 16 is started to allow the vacuum pump 16 to suction air, and then the suction pipe 18 and the ventilation pipe 17 are used to allow the bottom ends of the two suction pipes 18 to suction air. When the bottom ends of the two suction pipes 18 are suctioning air, the two ends of the top side of the touch screen will be adsorbed, and the two suction pipes 18 are located in the middle of the end side of the upper loading mold 9. Therefore, when the touch screen is adsorbed, the middle of the two end sides of the touch screen will be adsorbed, which can be more stable and avoid the phenomenon of offset, thereby achieving the positioning of the touch screen to improve stability and improve the quality of glue bonding during alignment.

[0037] In a further preferred embodiment of the present invention, Figure 1-4 As shown, two pulleys 19 are rotatably connected to both ends of the top side wall of the upper loading mold 9, and one end of the upper loading mold 9 is opened.

[0038] In this embodiment, the touch screen can slide in from one end of the loading mold opening, and the pulley 19 is arranged to reduce the friction on the top side of the touch screen to avoid damage due to friction. The depth of the mold groove on the bottom side of the upper loading mold 9 is smaller than the thickness of the touch screen, which is convenient for aligning and gluing with the LCD screen, thereby protecting the touch screen while avoiding offset.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
