[0006] Therefore, in the prior art, the waste material must be removed by setting the Chuck flag. If the waste material is not removed, the remaining waste material may detach from the substrate and affect the subsequent process.
Therefore, the cutting machine needs to stop and wait for the veneer waste material to lead away after performing the third cut (3), the fifth cut (5), the ninth cut (9) and the eleventh cut (11) respectively. To make the production tact time (Tact time) longer, that is, the entire production process takes more time, which is not conducive to improving production efficiency

Embodiment Construction
[0027] The present invention will be described in detail below in conjunction with specific drawings and embodiments.
[0028] Refer to Figure 4 And combine Figure 5 In an embodiment of the method for cutting a liquid crystal display panel of the present invention, a plurality of effective panel units 501 are provided on the liquid crystal display panel 50, and two adjacent effective panel units 501 are connected by a cutting waste area 502. The cutting method Including the following steps:
[0029] Step S401: Cut between each effective board unit and the cutting waste material area in turn to separate multiple effective board units, and after at least part of the effective board units and the respective connected cutting waste material areas are cut, they are not matched with each other. The waste material in the cutting waste material area connected with part of the effective board unit is clamped, and the waste material is kept connected with the corresponding effective board ...

The invention discloses a cutting method and cutting device for liquid crystal display panels. According to the cutting method, waste materials in cutting waste material areas respectively connected with a part of effective panel units don't be clamped, after the part of effective panel units and the respectively connected cutting waste material areas are cut, that means waste materials don't be clamped during cutting, a residual part of waste materials are removed in a later waster material detecting and fracturing mechanism. By adopting the above method, time of a whole production flow can be shortened, the production efficiency can be raised.
Description
Technical field [0001] The invention relates to the technical field of liquid crystal manufacturing, in particular to a cutting method and a cutting device for a liquid crystal display panel. Background technique [0002] Liquid crystal displays have the characteristics of lightness and thinness, high brightness, low power consumption, and soft pictures. They are popular among users and are the mainstream displays in the current display market. [0003] The main unit of the liquid crystal display is a liquid crystal panel. The liquid crystal panel is usually composed of two upper and lower glass substrates with thin film layers formed on the surfaces and a liquid crystal layer between the two glass substrates. In the manufacturing process of the liquid crystal panel, a whole large panel is usually processed first, and then the large panel is cut into the required small-sized panel units. [0004] Refer to figure 1 Taking a 28" liquid crystal panel as an example, six small panel unit...
