Generally, a Liquid Crystal display panel includes a Color Filter (CF) substrate, a Thin Film Transistor (TFT) array substrate, a Liquid Crystal (LC) sandwiched between the Color Filter substrate and the TFT substrate, and a Sealant frame (Sealant). In the manufacturing process of the liquid crystal panel, after the TFT substrate and the CF substrate are bonded, the edges of two sides or four sides of the liquid crystal panel generally need to be cut off by a cutter wheel.
In the prior art, the edge of the liquid crystal panel is generally cut off by a cutter. Among these, the cutting machine generally comprises: the bearing platform is used for bearing the glass substrate to be cut; the cutting mechanism is used for cutting and scribing the substrate, so that the subsequent splitting process is facilitated; the splinter mechanism comprises an upper splint and a lower splint and is used for splintering to separate the residual materials of the CF substrate; and the residual material collecting mechanism is used for collecting and mincing residual materials.
As shown in fig. 1 and 2, the existing cutting mechanism mainly includes a base 1, an upper tool rest 2 disposed on the base 1, an upper tool bit 3 mounted on the upper tool rest 2, and a lower tool bit 5 mounted in the base 1, wherein the base 1 has an open-ended receiving groove 4, the lower tool bit 5 is mounted in the receiving groove 4, the upper tool rest 2 includes a vertical portion connected to the base 1 and located above one side of the receiving groove 4, and a horizontal portion connected to the vertical portion and located above the receiving groove 4, the upper tool bit 3 is mounted on the upper tool rest 2 and can slide above the receiving groove 4, a horizontal lower slide rail 6 is disposed on an inner wall of the receiving groove 4 opposite to the upper tool rest 2, and the lower tool bit 5 is mounted on the lower slide rail 6 and can slide in the receiving groove 4 along the lower slide rail 6.
When the edge of the liquid crystal panel is cut off by using the cutting machine, the cutting process specifically comprises the steps of enabling the TFT substrate to face upwards and the CF substrate to face downwards, then enabling a cutter wheel of an upper cutter head 3 of the cutting mechanism to cut into the TFT substrate to a certain depth from top to bottom and keep a certain cutter pressure, enabling a cutter wheel of a lower cutter head 5 to cut into the CF substrate to a certain depth from bottom to top and keep a certain cutter pressure, and then enabling the upper cutter head 3 and the lower cutter head 5 to move along a cutting line under the driving of a horizontal motor, so that cutting marks and seepage force are generated on the TFT substrate and the CF substrate. After the cutting mark is generated, the edges of the TFT substrate and the CF substrate are clamped by clamping plates (the position of the clamping plates is based on the position of the cutting line), and the TFT substrate and the CF substrate are bent upwards in a servo mode and twisted by a certain angle to simulate manual splitting action, so that residual materials on the TFT substrate and the CF substrate penetrate and split along the direction of the cutting line.
Therefore, in the cutting machine, the lower cutter head 5 belongs to one of the most important parts in the whole machine, the abnormal frequency is high, the line damage, the pipeline abrasion and other abnormalities often occur, but because the design space of the cutting mechanism base 1 and the accommodating groove 4 is narrow, the dismounting and the checking are very difficult, and each abnormality can cause the downtime for a long time, thereby affecting the equipment production.
