Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary equipment for glass processing, in particular to a fixing fixture for assisting glass substrate detection. Background Art
[0002] With the continuous development of electronic technology, more and more TFT-LCD (Thin Film Transistor-Liquid Crystal Display) are widely used in various electronic products. TFT-LCD display screens are usually made of TFT-LCD glass substrates. As a defect-free glass, TFT-LCD glass substrates have meticulous and strict quality control requirements in their production process, which directly determine the product quality of glass substrates. Glass substrates are a basic component of liquid crystal display devices and one of the key basic materials in the flat panel display industry. It directly affects the performance of display products. For example, key indicators such as the resolution, imaging quality, transmittance, and strength of display screens are closely related to the performance of glass substrates. Therefore, high efficiency and high yield rate in the production and manufacturing of glass substrates are increasingly becoming the key to the manufacturing process. In order to meet market demand, semi-finished glass substrates need to go through precision cutting, grinding, cleaning, inspection and packaging processes before they can become qualified finished products. Among them, the grinding process is a very important process. It requires grinding of sharp edges and corners to eliminate the tiny chipping and tiny cracks on the edges caused by cutting the glass substrate, so as to remove internal stress and prevent broken screens. Therefore, display panel companies not only have strict requirements on edge cleanliness, but also have strict technical index requirements on the edge grinding quality of glass substrates. It is also one of the key factors in measuring whether the glass substrate can enter the subsequent process.
[0003] At present, the key indicators for evaluating the edge grinding quality of glass substrates are contact probe measurement of roughness and non-contact microscopic morphology measurement. Both measurement methods require the glass plate to be cut and placed upright to measure the edge grinding quality. Non-contact microscopic morphology measurement requires the glass plate to be fixed. However, the liquid crystal glass substrate is ultra-thin glass and cannot be placed upright after cutting. The sample is prone to shaking when manually grasped and photographed, and the photo is blurred, affecting the measurement accuracy. Therefore, a fixing tool is required to assist in the detection of the edge grinding state of the glass substrate to assist in the test and evaluation of the edge grinding quality of the glass plate.

[0025] The side of the baffle 3 is provided with one or more screws 5; specifically, the screws 5 are provided with two, the screws 5 are threadedly connected to the placing base 1, and the screws 5 are connected to the pushing assembly 6; the pushing assembly 6 is used to drive the screws 5 to rotate to push the baffle 3 to move to clamp the glass 4 to be tested. The pushing assembly 6 includes an outer box 61, a rotating pedal 62, a limit rope 63, a driving gear 64 and a driven gear 65, as shown in FIG. Figure 1 and Figure 2 As shown, the outer box 61 is fixed to the side of the placement base 1, and the inner part of the outer box 61 is rotatably connected with a driving gear 64; the driving gear 64 is connected to a rotating pedal 62, and a limiting rope 63 is fixed to the side of the rotating pedal 62; the driving gear 64 meshes with two driven gears 65, and the two driven gears 65 are respectively connected to the two screw rods 5; the rotating pedal 62 adopts a "Z"-shaped structure, and a limiting rope 63 is fixed to the side of the rotating pedal 62; the rotating pedal 62 is rotatably connected to the outside of the outer box 61.
[0026] When fixing and clamping the glass 4 to be tested, the glass 4 to be tested is placed in the placement groove 11, and then the operator places his foot on the rotating pedal 62, and uses the rotating pedal 62 and the limiting rope 63 to fix the foot. The operator steps on the rotating pedal 62 to rotate the rotating pedal 62. When the rotating pedal 62 rotates, it drives the driving gear 64 to rotate, and then drives the two driven gears 65 to rotate. When the two driven gears 65 rotate, they drive the two screws 5 to rotate, and then the two screws 5 are extended and retracted in the placement groove 11, driving the baffle 3 to move in the placement groove 11, so as to clamp or loosen the glass 4 to be tested.
