[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1-2 As shown, the utility model provides a liquid crystal glass substrate edge grinding device, comprising two sets of edge support mechanisms 2 arranged relatively to each other, respectively supporting and fixing two edges of a liquid crystal glass substrate 1, so as to facilitate grinding of the two edges of the liquid crystal glass substrate 1 at the same time, an auxiliary support mechanism 3 is arranged between the two sets of edge support mechanisms 2, so as to support the middle part between the two edges of the liquid crystal glass substrate 1, so as to prevent the local settlement of the liquid crystal glass substrate 1 due to gravity, two movable guide rails 4 are arranged relatively to each other on the outer sides of the two sets of edge support mechanisms 2, two sets of grinding mechanisms 5 are slidably connected to the movable guide rails 4, and the two sets of grinding mechanisms 5 are driven by a driving mechanism to move toward / reversely along the direction of the movable guide rails 4, so as to grind the two edges of the liquid crystal glass substrate 1 supported and fixed on the two sets of edge support mechanisms 2 from both ends of the two edges of the liquid crystal glass substrate 1 at the same time, and compared with the traditional grinding method, the method of grinding the two edges from both ends of the two edges to the middle at the same time shortens the processing time by half, significantly reduces the production cycle of the grinding process, and improves the production efficiency of the liquid crystal glass substrate 1.

[0017] The edge support mechanism 2 includes a workbench 21 for supporting the edge of the liquid crystal glass substrate 1. The workbench 21 is evenly distributed with a plurality of adsorption holes 22. The plurality of adsorption holes 22 are respectively connected to a negative pressure vacuum pump through a negative pressure pipeline to adsorb and fix the edge of the liquid crystal glass substrate 1 supported on the workbench 21, so as to ensure that the liquid crystal glass substrate 1 remains in a stable state during the edge grinding process. A layer of table cloth is posted on the workbench 1 to prevent the table surface of the workbench 1 from scratching the surface of the liquid crystal glass substrate. The table cloth is evenly distributed with a plurality of air holes corresponding to the adsorption holes 22 to expose the adsorption holes 22, so as to facilitate the adsorption and fixation of the edge of the liquid crystal glass substrate.

[0018] Among them, the auxiliary support mechanism 3 includes a plurality of support columns 31 evenly distributed between the two groups of edge support mechanisms 2. A brush support block 32 is arranged on the top of the support column 31 to support the remaining parts of the liquid crystal glass substrate 1 except the edge. Since the auxiliary support mechanism 3 is used to support the non-processing parts of the liquid crystal glass substrate 1 and does not involve processing operations, there is no need to increase adsorption and fixation. The support requirements can be met by relying on the brush support block 32 on the support column 31, thereby reducing the production and processing costs.

[0019] The grinding mechanism 5 includes a slide 51 slidably mounted on the movable guide rail 4, and a plurality of grinding wheels 52 are mounted on one side of the slide 51 close to the edge support mechanism 2, so that when the slide 51 moves along the movable guide rail 4 under the drive of the driving mechanism, the edge of the liquid crystal glass substrate 1 supported and fixed on the edge support mechanism 2 is inserted into the wheel groove of the grinding wheel 52, and the edge of the liquid crystal glass substrate 1 is ground. The grinding mechanism 5 also includes an anti-collision beam 53, which is mounted on one side of the slide 51. The anti-collision beams 53 of the two groups of grinding mechanisms 5 slidably connected to the same movable guide rail 4 are mounted face to face, so as to prevent the two groups of grinding mechanisms 5 from colliding when the two groups of grinding mechanisms 5 move toward the center of the liquid crystal glass substrate at the same time. The driving mechanism is driven by a linear motor module or a hydraulic cylinder, and the grinding wheel 52 is driven by a grinding wheel motor.

[0020] When the utility model is working, the liquid crystal glass substrate 1 is transported from the upstream process to the grinding process, the edge of the liquid crystal glass substrate 1 is carried by the work tables 21 on both sides, the negative pressure vacuum pump is turned on, and the edge of the liquid crystal glass substrate 1 is adsorbed and fixed through the adsorption holes 22 to ensure a smooth edge grinding process, the auxiliary support mechanism 3 supports the rest of the liquid crystal glass substrate 1 except the edge, and the brush support block 32 is arranged on the support column 31 to prevent the liquid crystal glass substrate 1 from local settlement due to gravity; when the vacuum of the work tables 21 on both sides is completely established and the edge of the liquid crystal glass substrate 1 is firmly adsorbed, the driving mechanism and the grinding wheel motor are started. The driving mechanism drives the grinding mechanism 5 on the moving guide rails 4 outside the two edges of the liquid crystal glass substrate 1 to move simultaneously from the two ends of the liquid crystal glass substrate 1 to the center of the liquid crystal glass substrate 1 along the direction of the moving guide rails 4. At this time, the two edges of the liquid crystal glass substrate 1 are respectively inserted into the wheel grooves of the grinding wheels 52 on both sides, and the grinding wheel motor drives the grinding wheel 220 to grind the edges of the liquid crystal glass substrate 1; when the two grinding mechanisms 3 on the same moving guide rail 4 move synchronously to the center of the liquid crystal glass substrate 1, the anti-collision beams 53 installed face to face on one side of the two grinding mechanisms 3 buffer each other to avoid collision between the two grinding mechanisms 3.

[0021] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
