Description

Technical Field

[0001] The invention relates to the technical field of edge grinding of liquid crystal substrates, and in particular to an edge grinding mechanism of a liquid crystal substrate. Background Art

[0002] With the continuous development of electronic technology, TFT-LCD (liquid crystal display) is widely used in various electronic products, and the liquid crystal substrate is an important component of the display. In the production process of liquid crystal substrate, the grinding process is mainly to perform deep processing on the edges and corners of the substrate. The grinding quality of the edges and corners is directly related to the quality of the substrate.

[0003] When grinding a conventional liquid crystal substrate, first, the glass substrate to be ground is conveyed between two groups of grinding equipment, and then, by starting the forward extension component in the grinding equipment, the grinding wheel in the grinding equipment is brought into contact with one side of the liquid crystal display screen. After the contact, the grinding motor is started, and the grinding wheel is driven by the grinding motor to rotate, and the edge of the liquid crystal display screen is started to be ground. During the grinding, the cooling device needs to be started, and the cooling liquid is injected into the gap between the grinding wheel and the glass substrate through the device to start cooling the grinding part. During the grinding process, the grinding wheel and the grinding motor are driven by the grinding device to translate, so that the grinding of liquid crystal displays of different lengths can be realized. When the grinding of both sides of the liquid crystal substrate is completed, it is conveyed to another group of grinding equipment through the conveying device, and the other two sides are ground.

[0004] Because when grinding the liquid crystal substrate, two groups of grinding equipment are needed to grind it, and the two groups of equipment are placed separately, which leads to an increase in the grinding cost and a large floor space. At the same time, during grinding, it is necessary to inject coolant into the grinding area, and the traditional coolant is sprayed by a nozzle. Therefore, when the coolant contacts the grinding wheel and the glass substrate, part of the coolant will be thrown out by the grinding wheel, and another small part of the coolant will remain on the glass substrate, resulting in a waste of coolant and the problem that it cannot be recovered.

[0061] The conveying motor 32 in the first conveying assembly 3 and the second conveying assembly 4 drives the transmission shaft 33 to rotate, thereby driving the multiple conveying shafts 34 to rotate. When the conveying shafts 34 rotate, the conveying wheels 35 will be driven to rotate. When the conveying wheels 35 rotate, the glass substrate can be conveyed.

[0062] In order to limit the position of the glass during transportation and avoid the glass from being deflected during transportation, the present embodiment provides the following technical solutions:

[0065] The working principle and use process of the present invention:

[0066] In use:

[0067] The first step is to start the side block pneumatic rod 761. When the side block pneumatic rod 761 works, it will drive the side block rod 762 to move upward.

[0068] The second step is to place the glass to be processed on the first conveyor assembly 3 and the second conveyor assembly 4, and drive the glass substrate forward through the first conveyor assembly 3 and the second conveyor assembly 4;

[0069] In the third step, the two sets of positioning telescopic rods 52 in the first auxiliary positioning assembly 5 and the second auxiliary positioning assembly 6 drive the two sets of positioning wheels 54 to move forward, thereby achieving limited clamping of both sides of the glass;

[0071] Step 5: Lift the hydraulic rod 71 to drive the support component 75 to move upward, so that the glass is lifted by the support component 75. When lifting, the glass can be adsorbed by the first suction cup 754 and the second suction cup 756 to avoid the glass from moving during grinding.

[0072] Step 6: At this time, the protruding assembly 84 in the first polishing mechanism 8 and the second polishing mechanism 9 drives the polishing wheel 863 to fit the edge of the glass substrate, and starts to polish both sides of the glass substrate;

[0073] Step 7: After polishing, the first polishing mechanism 8 and the second polishing mechanism 9 will be away from the glass substrate. At the same time, the side blocking pneumatic rod 761 drives the side blocking rod 762 to move downward to be stored. After storage, the rotating motor 73 is started, and the rotating motor 73 drives the rotating support component 75 to rotate. When the support component 75 rotates 90 degrees, it will also drive the glass substrate to rotate 90 degrees.

[0074] Step 8: Start the first grinding mechanism 8 and the second grinding mechanism 9 again, so that the grinding wheels 856 in the first grinding mechanism 8 and the second grinding mechanism 9 are reset. After the reset, it is convenient to grind the other two sides of the glass substrate later.

[0075] In the ninth step, after the grinding is completed, the lifting and rotating assembly 7 is reset as a whole, and the glass substrate is also reset when reset, so that the glass substrate is located on the first conveying assembly 3 and the second conveying assembly 4, and then it is output through the first conveying assembly 3 and the second conveying assembly 4.
