Problems solved by technology

[0005] However, if the same method is used for liquid crystal display (hereinafter referred to as LCD) panels before ultraviolet light (hereinafter referred to as UV) curing substrate trimming, it will be because too much stress is applied to the liquid crystal substrate before polymer alignment treatment. , but can not be trimmed, resulting in substandard products
That is, it is not possible to trim the edge of the substrate for the LCD panel before the UV curing step

Embodiment 1

[0031] Please refer to the first embodiment Figure 1 to Figure 10 As shown, A is the loading channel of the substrate X before the UV curing step of the LCD panel, and B is a plurality of workbenches, which are arranged in parallel in front of the loading channel A along the loading direction and have multiple ejection channels. The air hole 1 can eject air to float the substrate X and generate suction to keep the substrate X and the workbench B at a certain distance. C is the substrate X that can be transported on the workbench B and completed the edge processing (the edge has been processed). Of moving out of the channel.

[0032] In this embodiment, the carrying-in channel A and the carrying-out channel C are a roller conveyor belt as shown in the figure, however, they are not limited to this.

[0033] The plural workbenches B in this embodiment are provided with a hollow horizontally wide box 2 as shown in the figure, and the top wall of the box 2 is provided with a plurality ...

Embodiment 2

[0070] Secondly, please refer to figure 2 , Figure 7 , Picture 11 To illustrate the second embodiment.

[0071] The side line of the substrate X is covered (inserted) on the rear side of the scribing line formed by the cutter 39 of the cutter carriage 36, and on the lower surface of the CF board 12, a suction port 81 is arranged. Box 82.

[0072] A suction hose (not shown) is connected to the exhaust port 83 of the suction box 82.

[0073] In this way, the scraps when scribing with the cutter 39 can be sucked to the suction box 82.

Abstract

The invention relates to a processing apparatus for cutting edges of substrate of liquid crystal display panels, capable of performing processing without imposing too much stress on the liquid crystal substrates prior to alignment treatment on polymers while processing the cutting edges for the substrates before the liquid crystal display panel is performed with an ultraviolet curing step. The invention uses following equipment to implement cutting process: an in-line moving-in channel; working platforms aligned side by side and having small pore groups implementing the air spray to float and suck the substrates; taking-in paws arranged at the moving-out channel to move the substrates to the working platforms from the moving-in channel; taking-out paws for moving the substrates on the working platform to the moving-out channel; and a twist cutting device utilizing a cutting knife below CF panel edge of forming the substrate on the working platform to scribe lines and twisting and cutting the line scribing portion.

Description

Technical field [0001] The invention relates to a processing device for a liquid crystal display panel used for cutting the edges of an ultraviolet (UV) hardened front substrate. Background technique [0002] The technique used to cut the edge of the glass substrate is a well-known technique (refer to Patent Document 1). [0003] Patent Document 1 is Japanese Patent Application Laid-Open No. 2010-26267. [0004] The processing method of Patent Document 1 is to produce a cutting line on the glass substrate with a cutting knife, and then divide the cutting line by a dividing device that applies stress. [0005] However, if the same method is used for liquid crystal display (hereinafter referred to as LCD) panels, when the substrate is trimmed before ultraviolet light (hereinafter referred to as UV) curing, excessive stress will be applied to the liquid crystal substrate before the polymer alignment treatment. , And can not be processed for trimming, and then produce defective products....
