Description

Technical Field

[0001] This utility model relates to a suction cup for feeding a diffusion plate. Background Technology

[0002] A diffusion plate is a key functional material in the production of optoelectronic display devices such as LCD screens. Its main function is to transform point or line light sources in the backlight module into uniform surface light sources, ensuring the brightness consistency and color reproduction of the display panel. With the rapid development of display technology towards larger sizes, higher resolutions, and greater flexibility, the size specifications of diffusion plates are becoming increasingly diverse, and the requirements for their handling efficiency during production have also significantly increased.

[0003] In existing production processes, diffuser plates are typically loaded and transferred to different workstations using a vacuum suction cup system. Vacuum suction cups utilize the principle of negative pressure adsorption, forming a sealed cavity between the suction cup and the diffuser plate surface using a pneumatic or electric vacuum generator, and then using atmospheric pressure to grip and transport the plate. However, traditional vacuum suction cups suffer from the following technical bottlenecks:

[0004] Existing suction cup structures typically employ a fixed array layout, with pre-set suction cup spacing and distribution patterns, making them suitable only for diffuser plates of specific sizes. When product specifications change (e.g., from 32 inches to 65 inches), the suction cups cannot dynamically adjust their adsorption positions, resulting in insufficient adsorption force at the edges or redundant adsorption in the center, which can easily lead to problems such as plate misalignment, warping, or even detachment. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a suction cup for loading onto a diffusion plate.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a diffusion plate loading suction cup, including a suction cup frame, wherein the front, rear, left and right sides of the suction cup frame are provided with mounting straight grooves for mounting suction cup assemblies, the number of suction cup assemblies is several, and each includes a strip-shaped mounting plate, each mounting plate is provided with a long through groove, each long through groove is provided with a fastener that locks onto the mounting straight groove, and each end of the mounting plate is provided with a vacuum suction cup.

[0007] Preferably, the suction cup frame is composed of a lower square frame and an upper square frame, and the upper and lower square frames are fixed together as one unit by vertical connecting rods located at the four corners.

[0008] Preferably, the mounting slots are all located on the top surface of the lower square frame.

[0009] Preferably, the vertical cross-section of the mounting groove is convex.

[0010] Preferably, both ends of the mounting plate are provided with rounded corners.

[0011] Preferably, all the fasteners include wing screws, the threaded shank of each wing screw passes through the corresponding through slot and extends into the corresponding mounting slot. Each mounting slot is provided with a locking block, and each locking block is provided with an internal threaded hole and screwed to the threaded shank of the wing screw, so that when locked, the locking block is located on the stepped surface between the wide and narrow parts of the "U"-shaped mounting slot.

[0012] Preferably, each of the vacuum suction cups has a vertical rigid suction pipe fixed to its top, and the top of each rigid suction pipe is connected to a flexible suction pipe, which is connected to a vacuum pump.

[0013] Preferably, each end of the mounting plate is fixed with a bushing for vertically inserting a rigid suction pipe.

[0014] Preferably, the rigid suction pipe is coaxially fixed with an upper limit flange above the bushing, and the rigid suction pipe is coaxially fixed with a lower limit flange below the bushing.

[0015] Preferably, a buffer spring is fitted on the outer periphery of the rigid suction pipe between the lower limiting flange and the bottom end of the bushing.

[0016] Compared with the prior art, the present invention has the following advantages: the front, rear, left, and right sides of the suction cup on the diffusion plate are provided with mounting grooves for mounting suction cup assemblies, and the number of suction cup assemblies is several, which can achieve:

[0017] 1. The front and rear suction cup assemblies can be used to adjust the adsorption area along the width of the diffuser plate, while the left and right suction cup assemblies can be used to adjust the adsorption area along the length of the diffuser plate.

[0018] 2. In addition to the adjustable mounting position on the suction cup frame, the suction cup assembly itself can also be adjusted by horizontal rotation to change the suction position.

[0019] When the diffuser plate is switched within a certain specification range, the suction cup can adjust the adsorption position to ensure that the adsorption force in the edge area and the center area of ​​the diffuser plate is sufficient, thus avoiding problems such as plate displacement, warping, or even detachment.

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] like Figures 1-4 As shown, this embodiment provides a diffusion plate loading suction cup, including a suction cup frame 1. The front, rear, left, and right sides of the suction cup frame are provided with mounting grooves 3 for mounting suction cup assemblies 2. The number of suction cup assemblies is several, and each includes a strip-shaped mounting plate 4. Each mounting plate has a long through groove 5. Each long through groove is provided with a fastener 6 that locks onto the mounting groove. Each end of the mounting plate is provided with a vacuum suction cup 7.

[0029] In this embodiment of the utility model, the suction cup frame is composed of a lower square frame 8 and an upper square frame 9, and the upper and lower square frames are fixedly connected as one unit by vertical connecting rods 10 located at the four corners.

[0030] The upper square frame serves to connect to an external drive mechanism, which controls the movement and lifting of the suction cups on the diffuser plate. The external drive mechanism is existing technology and not an improvement in this case; therefore, it will not be elaborated upon here.

[0031] In this embodiment of the utility model, the mounting straight grooves are all provided on the top surface of the lower square frame.

[0032] In this embodiment of the utility model, the vertical cross-section of the mounting groove is convex.

[0033] In this embodiment of the invention, both ends of the mounting plate are provided with rounded corners.

[0034] In this embodiment of the utility model, the fasteners all include wing screws 11. The threaded rods of the wing screws all pass through the corresponding long through slots and extend downwards into the corresponding mounting straight slots. Each mounting straight slot is provided with a locking block 12. Each locking block is provided with an internal threaded hole and is screwed to the threaded rod of the wing screw, so that when locked, the locking block is pressed tightly against the stepped surface 13 between the wide and narrow parts of the "U"-shaped mounting straight slot.

[0035] In this embodiment of the invention, the top of each vacuum suction cup is fixedly provided with and connected to a vertical rigid suction pipe 14, the top end of each rigid suction pipe is connected to a flexible suction pipe 15, and the flexible suction pipe is connected to an external vacuum pump.

[0036] In this embodiment of the utility model, a bushing 16 for vertically inserting a rigid suction pipe is fixed on the end of each mounting plate.

[0037] In this embodiment of the utility model, an upper limit flange 17 is coaxially fixed on the rigid suction pipe above the bushing, and a lower limit flange 18 is coaxially fixed on the rigid suction pipe below the bushing.

[0038] In this embodiment of the utility model, a buffer spring 19 is fitted on the outer periphery of the hard suction pipe between the lower limiting flange and the bottom end of the bushing.

[0039] In this embodiment of the invention, the working principle of the feed suction cup on the diffusion plate is as follows:

[0040] The front and rear suction cup assemblies are used to adjust the adsorption area along the width of the diffuser plate 20, while the left and right suction cup assemblies are used to adjust the adsorption area along the length of the diffuser plate. The suction cup assemblies themselves can also be horizontally rotated to change the adsorption position. When vacuum suction cups are present in both the edge and center areas of the diffuser plate, the positions of the suction cup assemblies are fixed. This prevents problems such as plate displacement, warping, or even detachment during vacuum adsorption of the diffuser plate.

[0041] When the external drive mechanism drives the vacuum suction cup of the diffuser plate to descend to the top diffuser plate of the diffuser plate stack 21, at the moment the vacuum suction cup contacts the top surface of the top diffuser plate, as the vacuum suction cup descends a short distance further, the buffer spring will be compressed, which will play a buffering role when the vacuum suction cup contacts the top surface of the diffuser plate.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
