Description

Technical Field

[0001] The utility model provides an edge grinding machine, belonging to the technical field of edge grinding machines for glass covers of display devices, and particularly relates to an edge grinding machine for glass covers of display devices. Background Technique

[0002] A glass cover of a display device refers to a layer of transparent glass or plastic material covering the display screen of the display device. Its main function is to protect the display screen from physical damage such as scratches and impacts, and at the same time provide certain anti-fingerprint and anti-reflection characteristics to improve the user experience. Edge grinding treatment is carried out to remove the sharp parts at the edges of the glass cover, make it smoother, prevent it from cutting users during use or carrying, and also improve the appearance texture and overall aesthetics of the product. The edge grinding process usually includes steps such as rough grinding, fine grinding and polishing to ensure the smoothness and gloss of the edges.

[0003] During the edge treatment process of the glass cover, traditional edge grinding operations usually rely on manual adjustment by operators to ensure uniform grinding of the peripheral area of the glass cover. This manual adjustment method not only increases the complexity and labor intensity of the operation, thereby reducing production efficiency, but also due to the need for frequent position adjustment, operators may face potential safety risks when performing these adjustments. These risks include but are not limited to mechanical injuries, repetitive strain injuries, and equipment damage caused by improper operation. Therefore, in order to improve production efficiency and reduce operation risks, it is necessary to explore automated or semi-automated edge grinding technologies to reduce the dependence on manual operations. Summary of the Utility Model

[0004] In the embodiments of the present application, through an automated control system, the edge grinding angle and speed are precisely adjusted to ensure uniform edge grinding, improve efficiency, and reduce safety risks.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: An edge grinding machine for a glass cover of a display device includes a placement table, and a limiting structure is arranged above the placement table. The limiting structure includes a pair of concentric limiting rings corresponding to each other and distributed above the placement table. A fixing rod is movably connected between the concentric limiting rings through a limiting member, and an adjustment groove is arranged between the fixing rod and the limiting member.

[0006] Preferably: A bottom plate fixedly connected to the concentric limiting rings is arranged above the placement table. Fixing bolts penetrating through the bottom plate itself and inserted into the interior of the placement table are arranged on the inner side of the bottom plate. A conveying device arranged inside the placement table is arranged on one side of the limiting structure.

[0007] Preferably: A driving motor corresponding to the conveying device and fixedly connected to the fixing rod is arranged above the conveying device. A grinding roller is connected to the driving motor below through a rotating shaft penetrating through the fixing rod, and the grinding roller is in close contact with the conveying device.

[0008] Preferably, a T-shaped sliding block corresponding to the adjustment groove is fixedly connected below one end of the fixed rod away from the drive motor. A T-shaped rotating column fixedly connected to the limiting member is provided inside the sliding block, and the diameter of the limiting member is greater than the width of the sliding block.

[0009] Preferably, a drive shaft passing through itself is provided at one end of the adjustment groove inside the concentric limiting ring, and a drive device placed inside the placement table is correspondingly connected below the drive shaft.

[0010] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0011] In the present utility model, by providing a limiting structure above the placement table, the limiting structure limits the movement track of the limiting member by means of the concentric limiting ring. However, when the limiting member moves, the fixed rod movably connected to the limiting member can always keep its own orientation fixed under the action of the adjustment groove, so as to ensure that the movement track of the distal end of the fixed rod is consistent with the concentric limiting ring. Therefore, only a concentric limiting ring with the same shape and size needs to be replaced to automatically grind the edge of the cover glass of the corresponding shape, without the need for manual position adjustment.

[0012] Other advantages, objectives, and features of the present utility model will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present utility model.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] It should be noted that the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs; the terms used in the description of the present invention in this specification are only for the purpose of describing specific implementation manners and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0024] As Figure 1 and Figure 2 shown, a glass cover plate edge grinding machine for a display device includes a placement table 1, and is characterized in that: a limiting structure 2 is arranged above the placement table 1, and the limiting structure 2 includes a pair of correspondingly distributed concentric limiting rings 21 arranged above the placement table 1. A fixed rod 23 is movably connected between the concentric limiting rings 21 through a limiting member 22, and an adjustment groove 24 is arranged between the fixed rod 23 and the limiting member 22. After the conveying device 13 transports the fixed cover plate glass to the corresponding position, the driving motor 14 and the driving device are started. The driving device drives the limiting groove 24 to rotate around the fixed shaft 16, and the sliding block 25 slides in the limiting groove 24, so as to adapt to the position change of the limiting member 22. The fixed rod 23 drives the grinding roller 15 to move along a preset track, ensuring that the grinding track conforms to the shape of the cover plate glass; when grinding cover plate glasses of different batches are replaced, only the fixing bolts 12 need to be checked, and the bottom plate 11 and the corresponding concentric limiting rings 21 are replaced. The present invention has low cost, simple operation and convenient use.

[0025] In this embodiment, in the design of the automatic edging machine, the limiting structure 2 is arranged above the placing table 1. This structure precisely controls the movement path of the limiting member 2 through the concentric limiting ring 21. When the limiting member 2 makes dynamic adjustments, the fixed rod 23 movably connected thereto can maintain its direction unchanged with the assistance of the adjustment groove 24, ensuring that the movement trajectory of the distal end of the fixed rod 23 matches the trajectory of the concentric limiting ring 21. This design allows for automatically adapting to cover glass of different shapes for edging by simply replacing the concentric limiting ring 21 with the same geometric shape and size, without the need for manual position adjustment.

[0026] As Figure 2 and Figure 3 shown, a bottom plate 11 fixedly connected to the concentric limiting ring 21 is provided above the placing table 1. A fixing bolt 12 that penetrates itself and inserts into the interior of the placing table 1 is provided on the inner side of the bottom plate 11. A conveying device 13 placed inside the placing table 1 is provided on one side of the limiting structure 2. Above the conveying device 13, a driving motor 14 corresponding to itself and fixedly connected to the fixed rod 23 is provided. A grinding roller 15 is connected below the driving motor 14 through a rotating shaft that penetrates the fixed rod 23, and the grinding roller 15 is in close contact with the conveying device 13. A T-shaped sliding block 25 corresponding to the adjustment groove 24 is fixedly connected below the end of the fixed rod 23 far from the driving motor 14. A T-shaped rotating column 26 fixedly connected to the limiting member 2 is provided inside the sliding block 25, and the diameter of the limiting member 2 is greater than the width of the sliding block 25. A driving shaft 16 that penetrates itself is provided at one end of the adjustment groove 24 inside the concentric limiting ring 21, and a driving device placed inside the placing table 1 is correspondingly connected below the driving shaft 16.

[0027] In this embodiment, when the conveying device 13 transports the fixed cover glass to a predetermined position, the driving motor 14 and the driving device are activated. The driving device causes the limiting groove 24 to rotate around the fixed shaft 16, and the sliding block 25 moves within the limiting groove 24 to adapt to the position change of the limiting member 2. The fixed rod 23 then drives the grinding roller 15 to operate according to a predetermined movement trajectory, ensuring that the grinding trajectory precisely corresponds to the shape of the cover glass. When processing cover glass of different batches, simply adjusting the fixing bolt 12 and replacing the bottom plate 11 and the corresponding concentric limiting ring 21 can achieve rapid adaptation. With its low cost, simple operability, and high usability, the present utility model provides an economical and practical solution for users.

[0028] During use:

[0029] 1. Preparation stage:

[0030] First, ensure that all components are correctly installed on the placement table 1, including the concentric limit ring 21, the limiting member 22, the fixing rod 23, the adjustment groove 24, the bottom plate 11, the fixing bolt 12, the conveying device 13, the driving motor 14, the grinding roller 15, the sliding block 25, and the rotating column 26.

[0031] Check that all connections are secure and ensure that there are no loose components.

[0032] 2. Install the concentric limit ring:

[0033] Select a suitable concentric limit ring 21 according to the shape and size of the cover glass to be edge-ground, and install it in the limit structure 2 above the placement table 1.

[0034] 3. Fix the bottom plate and bolts:

[0035] Fix the bottom plate 11 above the placement table 1, and ensure that the fixing bolt 12 passes through the bottom plate and inserts into the interior of the placement table 1 to ensure the stability of the bottom plate 11.

[0036] 4. Place the cover glass:

[0037] Place the cover glass to be edge-ground on the placement table 1, ensuring that the position of the glass is correct so that the conveying device 13 can accurately transport the glass to the predetermined position.

[0038] 5. Start the conveying device:

[0039] Start the conveying device 13 to transport the cover glass to the predetermined position. The design of the conveying device 13 should ensure that the glass moves smoothly and accurately under the limit structure 2.

[0040] 6. Activate the driving motor and the driving device:

[0041] Start the driving motor 14 and the driving device. The driving device will drive the limit groove 24 to rotate around the fixed shaft 16, causing the sliding block 25 to move within the limit groove 24 to adapt to the position change of the limiting member 22.

[0042] 7. Perform the edge-grinding operation:

[0043] The fixing rod 23 drives the grinding roller 15 to operate according to a preset movement trajectory, ensuring that the grinding trajectory precisely corresponds to the shape of the cover glass. The grinding roller 15 is in close contact with the conveying device 13 to precisely grind the edge of the glass.

[0044] 8. Replace the batch of cover glass:

[0045] When it is necessary to replace different batches of cover glass for grinding, simply adjust the fixing bolt 12, replace the bottom plate 11 and the corresponding concentric limit ring 21 to achieve quick adaptation.

[0046] 9. Complete edge grinding:

[0047] Once the edge grinding operation is completed, the conveying device 13 transports the cover glass to the unloading position, and the operator can remove the edge-ground glass.

[0048] 10. Cleaning and maintenance:

[0049] After each use, clean and perform necessary maintenance on the device to ensure the long-term stable operation of the equipment.
