Problems solved by technology

Even under this kind of planning and design of multiple matching machines, the complexity of the grinding process will often cause poor grinding such as burns, and it is necessary to stop the machine regularly to adjust the process parameters such as the grinding amount, resulting in a low equipment utilization rate and failing to meet the design requirements.
[0003] Due to the particularity of substrate glass production, inconsistent production will have a great impact on the stability of product quality and product consistency, which will affect the production efficiency of the entire production line, reduce production capacity, and greatly increase the PAC Increase and decrease the comprehensive yield of finished products

Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0030] like figure 1 , figure 2 and image 3 As shown, according to the sequence of processing, a plane grinding wheel 1, a spherical grinding wheel 2 and two polishing wheels are arranged side by side along the grinding direction. The plane grinding wheel 1 is located at the front of the grinding direction. Polishing and grinding, two polishing wheels can achieve secondary polishing, further reducing the surface roughness of the glass, the distance between the bottom surface of the spherical grinding wheel 2 and the surface of the glass 4 after being ground by the flat grinding wheel 1 is greater than 0, reducing the single time of each grinding wheel Grinding amount, increase the overall grinding feed rate.

[0031] like Figure 4 and Figure 5 As shown, assume that the grinding surface size of the plane grinding wheel 1 is D, the grinding surface size of the ...

Abstract

The invention provides a TFT glass edge grinding device and method. The device comprises a face grinding wheel and a spherical grinding wheel which are arranged in the grinding direction side by side,the face grinding wheel is arranged in front of the advancing direction of the spherical grinding wheel, and the distance between the bottom face of the spherical grinding wheel and the glass surfaceground by the face grinding wheel is larger than or equal to 0. The grinding wheel carries out grinding at the first is set as the face grinding wheel, the single grinding face is effectively reduced, therefore, the grinding amount of one single grinding wheel is reduced, the overall grinding feed speed is improved on the condition of not affecting product quality and grinding precision, and theoperation ratio and the yield are improved.

Description

technical field [0001] The invention belongs to the field of glass substrate production, and relates to a TFT glass edge grinding device and method. Background technique [0002] At present, in the cold-end production process of glass substrates, the impact of takt on cost has become a key factor. In order to improve the comprehensive supporting capacity of the entire production line, it is necessary to match multiple grinding equipment for the bottleneck key process that affects the production takt during the design and planning of the production line. Design, improve the overall production beat. Even under this kind of planning and design of multiple matching machines, the complexity of the grinding process often causes poor grinding such as burns, and it is necessary to stop the machine regularly to adjust the process parameters such as the grinding amount, resulting in low equipment utilization rate and failing to meet the design requirements. [0003] Due to the partic...
