[0002] In the current liquid crystal glass substrate production line, the edges and corners of the semi-finished liquid crystal glass substrates are usually uneven and cracked, which will cause damage to the liquid crystal glass substrates during subsequent processing.

After each replacement of the carrier plate, the carrier plate needs to be re-leveled, resulting in a waste of a lot of time. Frequent switching greatly affects the utilization rate.

[0017] like Figure 1 As shown, the utility model provides a device for chamfering and grinding a liquid crystal glass substrate, comprising a base 1 and a carrying plate 2 installed on the base 1, wherein the carrying plate 2 is provided with a plurality of mutually independent negative pressure adsorption slots 3, and the plurality of negative pressure adsorption slots 3 are respectively connected to a plurality of independently working negative pressure adsorption devices, so that when liquid crystal glass substrates of different specifications are placed on the carrying plate 2, the negative pressure adsorption devices corresponding to the negative pressure adsorption slots 3 covered by the liquid crystal glass substrates are turned on to adsorb and fix the liquid crystal glass substrates on the carrying plate 2, so that the same carrying plate 2 can be used to adapt to liquid crystal glass substrates of different specifications. When encountering a switch of liquid crystal glass substrate products of different specifications, there is no need to replace the carrying plate 2, and only the negative pressure adsorption slots 3 on the carrying plate 2 need to be changed to work, thereby reducing the time for installing the carrying plate 2, greatly improving the efficiency of chamfering and grinding of the liquid crystal glass substrates, improving personnel safety, and saving production costs.

[0018] A notch 4 is provided at one corner of the carrier plate 2 so that the corresponding top corner of the liquid crystal glass substrate adsorbed and fixed on the carrier plate 2 can be extended out of the carrier plate 2 for chamfering and grinding. Through the large taper cutting angle design on the carrier plate 2, the extension amount of liquid crystal glass substrates of various specifications during chamfering and grinding is taken into account, which greatly reduces the probability of the grinding wheel colliding with the carrier plate 2 during chamfering and grinding.

[0019] The negative pressure adsorption tank body 3 includes a plurality of first adsorption tanks 31 arranged transversely, a plurality of second adsorption tanks 32 arranged longitudinally to connect the plurality of first adsorption tanks 31, and a negative pressure adsorption hole 33 penetrating the supporting plate 2.

[0020] Two adjacent negative pressure adsorption tank bodies 3 are connected through a connecting groove 34. A dynamic partition mechanism 35 is provided in the connecting groove 34 to control the opening and closing of the connecting groove 34. When the liquid crystal glass substrate covers multiple negative pressure adsorption tank bodies 3, the corresponding connecting grooves 34 are connected through the dynamic partition mechanism 35 to connect the multiple negative pressure adsorption tank bodies 3, so as to ensure that the adsorption force at each position of the glass substrate is the same, and to avoid damage caused by excessive local stress on the liquid crystal glass substrate. The dynamic partition mechanism 35 adopts a solenoid valve or a sealing baffle. When the dynamic partition mechanism 35 adopts a solenoid valve, the solenoid valve is fixedly installed in the connecting groove 34, and the opening and closing of the connecting groove 34 is controlled by controlling the solenoid valve.

One end of the support plate 2 is fixedly connected to the base 1 through a support rod 13, and the other end is connected to the base 1 through a horizontal adjustment mechanism to adjust the level of the support plate 2 to ensure the effect of chamfering and grinding. The horizontal adjustment mechanism includes a support screw 14 and an adjustment nut 15.

When liquid crystal glass substrate products of different specifications are switched, there is no need to replace the carrying plate, but only the negative pressure adsorption grooves on the carrying plate need to be changed to work. The applicability of the carrying plate when switching between liquid crystal glass substrates of various specifications is realized, the time for installing the carrying plate is reduced, the efficiency of chamfering and grinding the liquid crystal glass substrate is greatly improved, the safety of personnel is improved, and the production cost is saved. Through the large taper cutting angle design on the carrying plate, the corresponding top angle of the liquid crystal glass substrate adsorbed and fixed on the carrying plate is extended out of the carrying plate for chamfering and grinding, and the extension amount of liquid crystal glass substrates of various specifications during chamfering and grinding can be taken into account, which greatly reduces the probability of the grinding wheel colliding with the carrying plate during chamfering and grinding.
