step one
And (3) selecting a quartz stone or granite large plate with the length being more than 1m, the width being more than 1m and the thickness being more than 5mm, and flatly paving the quartz stone or granite large plate on the cutting table.
The preferred scheme is as follows: the length of the quartz stone or granite big plate is 1.5-2 m, the width is more than 1.5-2 m, and the thickness is 1.8-2.2 cm.
Step two
And cutting the two side edges of the large plate in the length direction to a depth of 30-40 cm along the length direction by adopting a double-knife bisecting machine. As shown in fig. 3.
Specifically, if a quartz stone or granite large plate with the length of 2m is selected, the quartz stone or granite large plate can be cut to the depth of 40cm, namely, both sides are cut to the depth of 80cm, and the remaining 120cm is used for further cutting.
In the invention, the cutters of the double-cutter bisecting machine are transversely arranged and positioned on the same horizontal line, so that the double-cutter bisecting machine can cut two side edges of the same quartz stone/granite.
Step three
And D, cutting the uncut part in the middle of the large plate prepared in the step two by adopting a stone bisecting machine or a stone rope saw, so that the large plate is divided into two vertically separated blocks.
According to the traditional stone bisection machine, a dovetail groove cutter is adopted, and a cutter head is embedded on a cutter belt.
Step four
And selecting a transparent acrylic plate with the thickness of more than 0.5mm, and compounding the transparent acrylic plate on the large plate positioned on the upper layer. The transparent acrylic plate is compounded on the large plate through epoxy resin glue.
Wherein, the preferred scheme is as follows: the thickness of the transparent acrylic plate is 0.5-1.5 mm.
The epoxy resin glue has low toxicity, small volatility, wide preparation ratio, simple and convenient operation, normal-temperature curing, strong bonding force, high light transmittance and good toughness, and is obviously superior to the common monomer amine curing agent.
Because the surface of the large plate has different flatness and curvature, different epoxy resin glues can be selected according to different large plates in order to improve the adhesion degree of the large plate.
Step five
And a sucker lifting tool is adopted to attract the transparent acrylic plate, lift the large plate and convey the large plate to other cutting tables and wait for cutting.
Suction cup spreaders are suitable for handling light, smooth surfaced objects and are generally composed of a vacuum cup, a spreader body, a vacuum generator and other control elements.

And repeatedly cutting the two divided large plates according to the second to fifth steps until the thickness of the large plate is 1 to 3mm, and compounding a transparent acrylic plate or other ultrathin plates with the thickness of more than 0.5mm on each large plate.
Preferably, the plate can be cut to the thickness of 2mm and the thickness of 1mm.
Step seven
And (5) performing fixed-thickness polishing on the large plate prepared in the step six.
Because the thickness of the large plate is very small, if the pressure is too large during grinding, the stone is easy to crack, and therefore, the grinding machine with the automatically adjustable pressure can be adopted to grind the large plate.
Step eight
And (4) compounding the two large plates prepared in the seventh step, wherein the transparent acrylic plates on the large plates are opposite, and an ultrathin sensor is compounded between the two transparent acrylic plates. The ultra-thin sensor is one of a capacitive touch sensor, an electromagnetic sensor or a radio frequency sensor.
According to the invention, through the matching of the double-knife bisecting machine and the stone bisecting machine, the cutting of quartz stone and granite is carried out in two steps, so that the situation of stone fragmentation during cutting is effectively avoided; the composite transparent acrylic plate has the functions of increasing the strength of the stone panel and transmitting light; by arranging the ultrathin sensor, the application range of the light-transmitting veneered stone composite board can be greatly improved, so that the light-transmitting veneered stone composite board can be manufactured into a natural stone touch switch panel, a projection screen of a laser projector, a natural stone induction cooker heating panel and the like.
The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
