The suction device is any suitable device capable of realizing vacuum pumping to enable the plate 3 to be adsorbed on the adsorption hole. The arrangement of the closed chamber can make each adsorption force more uniform.

Considering that the plate 3 adsorbed on the movable table 220 is relatively stressed during the rotation or movement of the movable table 220, in order to prevent the plate 3 from being displaced during the breaking process, in an example of the present invention, a second reinforced adsorption groove 221 is provided on a side of the movable table 220 facing the linear cutting groove 31, and the second reinforced adsorption groove 221 is adjacent to the linear cutting groove 31 and extends in a direction in which the linear cutting groove 31 extends.

Considering that when the LCD panel or the OLED substrate is cut, a narrow blank frame exists at the edge of the panel or the substrate, and such a narrow frame is not easily absorbed by the table top, in an example of the present invention, the plate material cutting groove extending and cutting apparatus further includes a chopping knife portion 600 disposed above the linear cutting groove 31; the chopping knife part 600 comprises a chopping knife lifting device 620 and a chopping knife 610, wherein the lifting end of the chopping knife lifting device 620 vertically extends downwards; the chopping knife 610 is installed at the lifting end, and the lower blade 611 of the chopping knife 610 is obliquely arranged along the extending direction of the linear cutting groove 31. When the frame is cut, cracks of the linear cutting grooves 31 can be sequentially transferred from one end to the other end of the linear cutting grooves 31 by the chopper 610, so that the frame is separated from the substrate.

If the width of the chopping block 610 corresponds to the width of the sheet material 3, the chopping and separating of the sheet material 3 can be realized by the up-and-down linear movement of the chopping block 610, but as shown in fig. 10, in an embodiment of the present invention, the width of the chopping block 610 is relatively narrow, the sheet material cutting groove extending and cutting apparatus further includes a transverse driving device (not shown) of the chopping block 610, and the chopping block lifting device 620 is installed above the cutting table and can move along the extending direction of the linear cutting groove 31, so as to drive the cutting edge 611 of the chopping block 610 to cut the sheet material 3 along the straight line. The lateral driving mechanism of the chopper 610 can be any suitable linear driving mechanism that can drive the knife rest of the chopper 610 to move along the second beam 601.

In summary, according to the present invention, when a plate is cut, a linear cutting groove is formed on the plate by the cutting groove processing portion, and then a combined pressure of bending force, shearing force, tension force, etc. is applied to the linear cutting groove of the plate by the synchronous action of the rotation driving device and the lifting device, so that the plate is more easily broken along the linear cutting groove. In addition, the descending displacement of the first linear driving device and the second linear driving device is different, so that the movable table top is inclined along the extending direction of the linear cutting groove, cracks are transmitted along the cutting groove line in sequence, and the cutting can be performed more easily. The device can reduce the labor load of operators, and the device realizes the cutting and separation of the plates by adopting a breaking mode, reduces the damage to the plates in the cutting process and can reduce the dust diffusion. In addition, the movable table top and the fixed table top of the plate cutting groove extending and cutting device are both provided with reinforced adsorption grooves, and the reinforced adsorption grooves provide stronger adsorption force for the breakage of the plates, so that the plate cutting groove extending and cutting device has high utilization value and use significance.
