Description

Technical Field

[0001] The utility model mainly relates to the technical field of inspection tables, in particular to an adjustable and scratch-resistant large plate inspection table. Background Art

[0002] The current market demand is for mass production of LCD panels. During the thinning production process, the substrate sizes of different customers are inconsistent, and the inspection of each process is complicated. Generally, a small-sized substrate is produced as a whole panel. This whole panel is composed of a combination of small-sized substrates connected to each other. The joints of the small-sized substrates are called invalid areas. The invalid areas mainly play a supporting and separating role, separating the small-sized substrates. In the subsequent processing process, the small-sized substrates will be separated by the invalid areas to form separate small-sized substrates.

[0003] After the large substrate is produced, its surface needs to be inspected manually with the naked eye. It is placed on an inspection table that can be tilted at a certain angle. With the help of the top light, the inspection table is tilted for careful observation and inspection.

[0004] Because the inspection is carried out on a large plate inspection table in a fixed position, products of different sizes all use the same large plate inspection table. It is impossible to have a large plate inspection table for each model size, and the same large plate table is difficult to accommodate different product sizes. Therefore, the development of this movable and adjustable large plate table can realize the inspection of different product sizes, reduce the risk of scratches caused by full-surface contact during the process, and provide effective measures for improving the quality of each process.

[0005] During the operation of the specific embodiment, the inventors found the following defects:

[0006] Currently, large glass substrates are placed directly on the inspection table, and their backs are in direct contact with the inspection table. During the tilt inspection of the inspection table, the glass substrate will move slightly, causing scratches on the side in contact with the inspection table. If the scratches are in the invalid area, it will not affect the quality of the glass substrate. However, the current scratch location cannot be controlled. If the scratches are in the valid area of ​​the glass substrate, it will affect the quality of the final product.

[0007] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0030] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0031] Refer to the attached Figure 1-3 , an adjustable and scratch-proof large plate inspection table, comprising symmetrically arranged supporting legs 1, the top of the supporting legs 1 is matched and connected to the inspection plate 3 through a rotating component 2, the top of the inspection plate 3 is symmetrically provided with horizontal slide rails 4, and the top of the horizontal slide rails 4 is slidably connected to the vertical supporting columns 5. This device can support and inspect large glass substrates of different sizes. When working, first adjust the vertical supporting columns 5 according to the invalid area distance between the large glass substrates, and align the vertical supporting columns 5 with the invalid area of ​​the large glass substrate. Then, place the large glass substrate of corresponding specifications on the top of the vertical supporting columns 5, so that the vertical supporting columns 5 at the bottom are aligned with the invalid area for supporting operation. In this way, even if the large glass substrate slides up and down, scratches will only occur in the invalid area, preventing the large glass substrate from being damaged during the inspection process. Since the vertical supporting columns 5 of the device can be slidably adjusted, it can adapt to the inspection operation of large glass substrates of different specifications.

[0032] The rotating assembly 2 includes an annular support block 21, the bottom of which is connected to the supporting leg 1, the internal rotation of the annular support block 21 is connected to the rotating column 22, the rear end of the rotating column 22 is connected to the L-shaped connecting column 23, the top of the L-shaped connecting column 23 is connected to the detection plate 3, and a tension adjustment mechanism 24 is provided on the side of the annular support block 21. The two ends of the bottom of the detection plate 3 are rotatably connected to the annular support block 21 through the L-shaped connecting column 23. When the horizontal angle of the detection plate 3 needs to be adjusted, the detection plate 3 can be directly rotated to rotate in the annular support block 21 through the rotating column 22. The tension adjustment mechanism 24 is used to adjust the friction force of the detection plate 3 when it rotates.

[0033] The tension adjustment mechanism 24 includes an adjustment block 241, and a threaded opening 242 is opened on the adjustment block 241. The threaded opening 242 is rotatably connected to the adjustment column 243. The bottom of the adjustment column 243 is rotatably connected to the arc-shaped friction block 244. The top of the adjustment column 243 is connected to the rotating cover 245. When it is necessary to adjust the rotation tightness of the detection plate 3, the adjustment column 243 can be rotated inward or outward as needed to drive the arc-shaped friction block 244 closer to or away from the rotating column 22. The rotating cover 245 facilitates the rotation of the adjustment column 243.

[0034] The bottom transverse slide rail 4 is higher than the vertical support column 5. When the large glass substrate is placed on the vertical support column 5, the bottom transverse slide rail 4 can play a supporting role to prevent the large glass substrate from falling to the bottom during rotation detection.

[0035] A support adjustment plate 31 is also provided in the middle of the detection plate 3, and a sliding groove 32 is opened in the middle of the top surface of the support adjustment plate 31. The sliding groove 32 matches and connects to the vertical support column 5. The support adjustment plate 31 can support the vertical support column 5 and improve the stability during support. At the same time, a slider is provided at the bottom of the vertical support column 5 to match the sliding groove 32, so that the vertical support column 5 can slide in the horizontal track.

[0036] The top of the vertical support column 5 is slidably connected to a positioning plate 51, one end of the positioning plate 51 is slidably connected to a guide column 52, and the other end of the positioning plate 51 is matched with a rotating screw 53. One end of the rotating screw 53 is rotatably connected to a first support block 54, and the other end passes through a second support block 55 and is connected to a rotation adjustment block 57. Both ends of the guide column 52 are connected to a third support block 56. In order to match large glass substrates of different specifications and improve the stability during the inspection of large glass substrates, a positioning plate 51 is provided. The positioning plate 51 can slide up and down along the vertical support column 5 to perform a preliminary limiting operation on the placed large glass substrate. When working, rotating the rotation adjustment block 57 can drive the rotating screw 53 to rotate, thereby driving the positioning plate 51 to slide on the guide column 52.

[0037] The vertical support column 5 is provided with a wrapping cloth made of anti-static material on the outside to further reduce the chance of scratching the large glass substrate.
