Description

Technical Field

[0001] The present application relates to the technical field of light guide plate assembly, and specifically to a guiding structure for light guide plate assembly. Background Art

[0002] A light guide plate is a component used in optical devices to change the propagation direction of light and increase the light transmission efficiency. During the production process of the light guide plate, it is necessary to assemble the produced light guide plate with the corresponding device and housing, and the light guide plate is often transported by a conveying device.

[0003] For example, a light guide plate oblique insertion assembly device with the publication number CN109573608A includes a positioning platform for positioning the light guide plate and an assembly manipulator for assembling the light guide plate, which are installed on the equipment frame. The equipment frame is connected to a carrier for placing the lamp frame to be assembled. The assembly manipulator can reciprocate between the positioning platform and the carrier. The assembly manipulator includes an assembly three-axis slide rail and an assembly suction cup assembly. The assembly suction cup assembly is hinged to the Z-axis assembly of the three-axis slide rail. A deflection cylinder for driving the assembly suction cup assembly to rotate is provided between the assembly suction cup assembly and the Z-axis assembly. The light guide plate can be inserted into the lamp frame in an inclined manner through the hinged assembly suction cup assembly and the deflection cylinder for driving its deflection, with relatively high assembly accuracy, and can avoid the situation where the light guide plate cannot be smoothly inserted into the lamp frame.

[0004] However, in the existing technology for light guide plate assembly, during the process of the light guide plate entering the assembly equipment through the conveying device, since the produced light guide plate needs to be manually inspected, the light guide plate with good inspection results will be put back on the conveying device again. This will result in different positions of the light guide plate on the conveying device when it is transported to the assembly equipment, which makes it inconvenient for the assembly equipment to pick up the light guide plate, or causes the position of the light guide plate to change when the assembly equipment picks up the light guide plate, and thus it is easy to have faults during assembly. Moreover, the existing conveying device for the light guide plate also has the situation that it is not convenient to adjust the spacing according to the widths of different light guide plates.

[0005] Therefore, it is necessary to provide a guiding structure for light guide plate assembly to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application, and therefore, it may include information that does not constitute the prior art. Utility Model Content

[0012] Preferably, a stepping motor is fixedly installed on the outer side wall of the support plate. The output shaft of the stepping motor is fixedly installed with one end of the first lead screw away from the connecting disk through a coupling.

[0034] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0035] Please refer to Figures 1-3 , the embodiment provided by the present utility model:

[0036] A guiding structure for assembling a light guide plate, including an upper conveying device 2 for transporting the light guide plate. The conveying device 2 is installed on a support frame 1, and the processed light guide plate is transported from one side to the other side through the conveyor belt on the conveying device 2. During this process, due to the different placement positions of the light guide plate each time, the position where the light guide plate is transported out from the conveying device 2 will also change. Therefore, a guiding structure is needed to guide the light guide plate on the conveyor belt.

[0037] On both sides of the top surface of the support frame 1, support plates 3 are respectively and fixedly installed. Inside the support plates 3, a synchronous bidirectional drive mechanism 5 is installed. Below the synchronous bidirectional drive mechanism 5, an adjusting component 6 is installed. On the side wall of the adjusting component 6, a guiding component 7 is installed through a threaded fastener.

[0038] Specifically, the synchronous bidirectional drive mechanism 5 includes a guide rail 51, a first lead screw 52, a connection disk 53, and a second lead screw 54. Both ends of the guide rail 51 are fixedly installed on the inner side wall of the support plate 3. The center of one side wall of the connection disk 53 is fixedly connected to the first lead screw 52, and the center of the other side wall of the connection disk 53 is fixedly connected to the second lead screw 54. A stepping motor 4 is fixedly installed on the outer side wall of the support plate 3. The output shaft of the stepping motor 4 is fixedly installed with one end of the first lead screw 52 away from the connection disk 53 through a coupling. The end of the second lead screw 54 away from the connection disk 53 is rotationally connected to the inner side wall of the support plate 3 through a bearing seat. Slide seats 55 are threadedly connected to the side walls of both the first lead screw 52 and the second lead screw 54. The slide seat 55 includes a threaded hole 551, a limiting block 552, and a mounting plate 553. A threaded hole 551 is formed inside the slide seat 55. The slide seat 55 is threadedly connected to the side walls of the first lead screw 52 and the second lead screw 54 respectively through the threaded hole 551 inside. The limiting block 552 is arranged on the top surface of the slide seat 55. The limiting block 552 is slidably connected in a chute formed inside the guide rail 51. The bottom of the slide seat 55 is integrally formed with a mounting plate 553.

[0039] When it is necessary to adjust the position of the guiding assembly 7 on the conveyor belt according to guiding plates of different widths, the forward and reverse rotations of the first lead screw 52 and the second lead screw 54 are driven by the stepping motor 4. Since the thread direction on the side wall of the first lead screw 52 is opposite to the thread direction on the side wall of the second lead screw 54, the two slide seats 55 can reciprocate and synchronously displace on the side walls of the first lead screw 52 and the second lead screw 54 respectively. Furthermore, the distance between the guiding assemblies 7 can be driven to be adjusted, so as to guide guiding plates of different widths.

[0040] Furthermore, the adjusting assembly 6 includes an adapter plate 61 and an oblong slot 62. The top surface of the adapter plate 61 is fixedly installed on the mounting plate 553 through screws. Oblong slots 62 are respectively formed on the side walls of the adapter plate 61. The threaded fasteners include a threaded rod 75 and a nut 76. The threaded rods 75 are respectively welded on the side walls of the mounting part 71. The threaded rods 75 respectively pass through the oblong slots 62 and are threadedly connected to the inside of the nuts 76. The side walls of the nuts 76 are in contact with the side walls of the adapter plate 61.

[0041] In order to be able to adjust the distance between the guiding assembly 7 and the conveyor belt, the nut 76 is loosened to enable the threaded rod 75 to slide in the oblong slot 62, and then the overall height of the guiding assembly 7 is driven to move, so as to prevent friction between the guiding assembly 7 and the conveyor belt due to the guiding assembly 7 being too low.

[0042] Specifically, position correction and guiding processing are performed on the light guide plate. The guiding assembly 7 includes a mounting portion 71, a first guiding plate 72, a second guiding plate 73, and a sliding roller 74. The bottom surface of the mounting portion 71 is integrally formed with the top surface of the second guiding plate 73. Rotating grooves are respectively formed in the side walls of the second guiding plate 73, and the sliding rollers 74 are respectively rotatably connected in the rotating grooves. The tail of the first guiding plate 72 is fixedly connected to the head of the second guiding plate 73, and the first guiding plate 72 is inclined outward at the head position of the second guiding plate 73. The second guiding plate 73 is arranged parallel to the conveying device 2.

[0043] Under the transmission of the conveying device 2, the light guide plate can move to the positions of the two first guiding plates 72. Since the first guiding plate 72 is inclined outward at the head position of the second guiding plate 73, the light guide plate with a position offset slides on the side wall of the first guiding plate 72 and corrects its position along the inclined first guiding plate 72. Then, the second guiding plate 73 arranged horizontally guides and processes the position of the light guide plate again. When the light guide plate enters between the second guiding plates 73, under the lubrication of the plurality of sliding rollers 74, it slides out from between the two second guiding plates 73. The light guide plate that slides out has its position changed on the conveyor belt under the guidance of the first guiding plate 72 and the second guiding plate 73, so as to facilitate the use of the assembly equipment for the light guide plate in the later stage.

[0044] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
