Grinding tool bit and grinding device

Abstract

The invention provides a grinding tool bit and a grinding device, belongs to the technical field of cleaning of display panels, and can solve the problems of grinding cloth waste and low production efficiency of a traditional grinding tool bit. The grinding tool bit comprises a slide rail, a first grinding component and a second grinding component respectively positioned at two ends of the slide rail and capable of sliding on the guide rail, and multiple filling components with different sizes; and the filling components with different sizes are arranged between the first grinding component and the second grinding component according to a width between the first grinding component and the second grinding component, and can be matched with the first grinding component and the second grinding component to form a complete bottom surface. When the grinding tool bit grinds the display panels with different sizes, the width of the bottom surface of the grinding tool bit can be adjusted to prevent the waste of grinding cloth caused by grinding of the surfaces of the display panels through a grinding tool bit with a wider bottom surface and to improve the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of display panel cleaning, and in particular relates to a grinding cutter head and a grinding device. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, and no radiation. It has developed rapidly in recent years and occupies a dominant position in the current flat panel display market. [0003] The current TFT-LCD production process needs to clean the LCD panel (Panel) before attaching the polarizer. The cleaning method used in the prior art is to grind the cutter head (such as figure 1 shown) for grinding to remove glass debris on the surface of the Panel. But there is following deficiency in this fixed-size grinding cutter head: [0004] 1. Due to the differences in the size of the Panel, if the size of the Panel is changed, in order to ensure that each position of the Panel is ground in place, the grinding tra...

Problems solved by technology

[0004] 1. Due to the difference in the size of the Panel, if the size of the Panel is changed, in order to ensure that the grinding of each position of the Panel is in place, the grinding track needs to be adjusted and verified, which increases the time for module replacement

[0005] 2. If the size of the grinding head is too large relative to the Panel, it is easy to cause the grinding cloth to run outside the Panel, resulting in waste of grinding cloth and affecting the utilization rate of materials; if the size of the grinding head is too small relative to the Panel, it is necessary to lengthen the grinding to ensure the grinding effect trajectory, resulting in reduced productivity
