DETAILED DESCRIPTION
[0021] like Figure 1-3 As shown, the utility model provides a substrate glass cutting device, including a workbench 10 and a double-axis truss 20 set on the workbench 10, the double-axis truss 20 is driven and connected to a lifting mechanism 30, the execution end of the lifting mechanism 30 is connected to a mounting frame 40, the mounting frame 40 is connected to a glass cutter 41 and a pressure sensor 42, and the pressure sensor 42 can adjust the height up and down; the substrate glass cutting device also includes a controller 35, and the controller 35 is communicatively connected with the lifting mechanism 30 and the pressure sensor 42.
[0022] Compared with the prior art, the substrate glass cutting device provided by the utility model has the glass to be cut placed on the workbench 10, and the dual-axis truss 20 drives the lifting mechanism 30 to move above the glass in a plane rectangular coordinate system, and the lifting mechanism 30 extends downward from the mounting frame 40, so that the glass cutter 41 on the mounting frame 40 contacts the glass to be cut and has a certain force, which is detected by the pressure sensor 42, and the pressure information of the glass cutter 41 on the glass is transmitted to the controller 35, and the controller 35 controls the lifting mechanism 30 to make the force of the glass cutter 41 on the glass to be cut within a set range, so that when cutting, it is possible to avoid the situation where the glass cutter 41 descends too much to cause damage to the substrate glass, or the glass cutter 41 does not descend enough to effectively cut the glass, thereby improving the accuracy of cutting glass and reducing damage to the glass.
[0023] It should be noted that the biaxial truss 20 can move forward and backward along two guide rails 21 arranged on both sides of the workbench 10 , and the transverse moving member 23 in the biaxial truss 20 can move left and right along the cross frame 22 .
[0024] In one embodiment, see Figure 3The lifting mechanism 30 includes a guide member 31, a motor 32, a screw rod 33 and a lifting plate 34. The guide member 31 and the motor 32 are fixedly arranged on the double-axis truss 20. The screw rod 33 is connected to the guide member 31 for fixed-axis rotation. The screw rod 33 is connected to the lifting plate 34 for transmission. The lifting plate 34 is connected to the guide member 31 for embedded sliding. The motor 32 is connected to the screw rod 33 for transmission. The mounting frame 40 is detachably fixedly arranged on the lifting plate 34. Specifically, two linear slide rails 311 are fixedly provided on one side of the guide member 31, and two sliders 341 are fixedly provided on one side of the lifting plate 34. The two sliders 341 are respectively slidably connected to the two linear slide rails 311, and the screw rod 33 is located between the two linear slide rails 311.

By rotating the external thread barrel 44 and moving it up and down along the screw hole of the internal thread block 43, it is convenient to calibrate and adjust the pressure sensor 42. It should be noted that the contact end of the pressure sensor 42 is connected to the main body through an elastic body.
