Problems solved by technology

In this way, when the life of the grinding belt expires, it is necessary to replace two grinding belts at one time, resulting in a waste of grinding belts
In addition, the plurality of rotating wheels 131 fixed on the upper grinding mechanism 111 and the plurality of rotating wheels 132 fixed on the lower grinding structure 112 rotate separately, causing their rotations to be asynchronous, so that the grinding belt used by the upper grinding mechanism 111 is opposite to the display panel 120. There is a difference between the force applied by the upper surface 121 of the upper surface 121 and the force applied by the grinding belt used by the lower grinding mechanism 112 to the lower surface 122 of the display panel 120, so that the flatness of the two surfaces of the display panel 120 is relatively poor.

Embodiment 1

[0020] Such as figure 2 As shown, the grinding device 200 according to the embodiment of the present invention includes: a grinding belt 210 , a belt transmission mechanism 220 and a belt pressing mechanism. Wherein, the number of grinding belt 210 is one, and the belt pressing mechanism includes an upper belt pressing mechanism 231 and a lower belt pressing mechanism 232 .

[0021] Specifically, the grinding belt 210 is passed through the grinding gap formed between the upper belt pressing mechanism 231 and the upper surface 310 of the panel 300 and the grinding gap formed between the lower belt pressing mechanism 232 and the lower surface 320 of the panel 300, so that The grinding belt 210 clamps the upper surface 310 and the lower surface 320 of the panel 300; the belt transmission mechanism 220 operates to drive the grinding belt 210 to rotate between the grinding gaps; The servo guide rail 240 is used to move up and down, so as to control whether the grinding belt 210 i...

Embodiment 2

[0027] As another optional embodiment, such as image 3 shown, with figure 2 The difference shown is that the above-mentioned first driven wheel set may only include one driven wheel 229a, and the diameter of the driven wheel 229a is larger than the thickness of the panel 300, so as to achieve the effect produced by the above-mentioned first driven wheel set. Similarly, the above-mentioned second driven wheel set may also include only one driven wheel 229b, and the diameter of the driven wheel 229b is also larger than the thickness of the panel 300, so as to achieve the effect produced by the above-mentioned second driven wheel set.

[0028] In summary, according to the grinding device of the embodiment of the present invention, only one grinding belt is used to grind the upper surface and the lower surface of the panel at the same time, reducing the number of grinding belts consumed in one grinding cycle, saving production costs, and A grinding belt rotates at the same time...

Abstract

The invention discloses a grinding device. The grinding device is used for grinding a panel (300) and comprises a grinding belt (210), belt transmission mechanisms (220) and belt pressing mechanisms, wherein the grinding belt (210) is used for clamping an upper surface (310) and a lower surface (320) of the panel (300), so that the two surfaces of the panel (300) can be ground simultaneously; the belt transmission mechanisms (220) are used for driving the grinding belt (210); the belt pressing mechanisms are used for pressing the grinding belt (210) on the upper surface (310) and the lower surface (320) of the panel (300). According to the grinding device, only one grinding belt is used for grinding the upper surface and the lower surface of the panel simultaneously, so that the quantity of the grinding belts consumed in one grinding cycle is reduced, and the production cost is reduced; the grinding belt rotates wholly, so that uniform forces are applied to the upper surface and the lower surface of the panel by the grinding belt, and the flatness of the two surfaces of the panel is improved.

Description

technical field [0001] The invention relates to a grinding device for panel grinding. More specifically, it relates to a grinding device for grinding a panel using a grinding belt. Background technique [0002] At present, in order to meet consumers' requirements for thinner and lighter display devices, liquid crystal displays (Liquid Crystal Display, LCD) with superior characteristics such as high image quality, good space utilization efficiency, low power consumption, and no radiation have become consumers' preferred displays. . [0003] As the main device of liquid crystal display, the display panel is a very precise electronic device. Taking an ordinary 19-inch display panel as an example, there are millions of pixels distributed on its surface. Therefore, if any unevenness occurs on the surface of the display panel, it will have a great impact on the overall display effect of the display panel. In order to ensure that the surface of the display panel has a certain fl...
