Specifically... Figure 6 In the example, A is an irregularly shaped glass. By having the positioning ball head 4364 of the positioning component 436 contact the edge of the irregularly shaped glass A, the size of the irregularly shaped glass A that can contact and be polished by the grinding head 435 can be limited, thereby achieving the effect of controlling the size of its chamfer.

[0036] Preferably, a positioning plate 421 is fixedly provided on the top edge of the slider 420, an internally threaded sleeve 423 is provided through the middle position of the positioning plate 421, and a connector 422 is fixedly provided on one side of the positioning plate 421.

[0038] Preferably, the pressure regulating component 450 includes a spring 451, an adjusting sleeve 452, and a positioning shaft 453. The positioning shaft 453 is horizontally fixed at the end of the housing 431 away from the grinding head 435, and the end of the positioning shaft 453 is movably inserted into the internal threaded sleeve 423.

Specifically, the pressure regulating component 450 can push the drive component 430 equipped with the grinding head 435 to move towards the glass, which can adapt to glass of different thicknesses, cope with differences in glass hardness, and cope with changes in the shape of the glass edge.

[0039] Working principle: First, the irregularly shaped glass is placed on the rotary drive unit 20 in the middle of the worktable 10, and the positioning plate 310 of the robotic arm 30 is used to position the center. Then, the rotary drive unit 20 drives the irregularly shaped glass to rotate, and the two sets of edge grinding mechanisms 40 are used to chamfer the edges of the irregularly shaped glass. When the edge grinding mechanism 40 is running, the linear driver 440 drives the slider 420 to move axially along the slide rail 410, so that the distance between the drive component 430 and the edge of the irregularly shaped glass is always within the set range. Then, the spring 451 of the pressure adjustment component 450 applies a pushing force to the drive component 430, so that the grinding head 435 contacts the edge of the irregularly shaped glass and ensures that its pressure is within a certain range. The motor a433, together with the transmission box 432, drives the two chucks 4 The 34 synchronous high-speed rotation, in conjunction with the grinding head 435 on the chuck 434, performs chamfering on the edge of the irregular glass. When the chamfering is completed, the middle position of the edge of the irregular glass will contact the positioning ball head 4364. At this time, the grinding head 435 cannot continue to grind along the axial direction of the irregular glass, thus achieving automatic stopping when the chamfering reaches the set value. When it is necessary to adjust the chamfering size, an external tool is used to rotate the hexagonal bushing 4363 and drive the screw 4362 to rotate, thereby adjusting the horizontal position of the positioning ball head 4364 at the end of the screw 4362, thereby achieving the function of controlling the chamfering depth. The pressure applied by the pressure adjustment component 450 can be adjusted according to the thickness and hardness of the glass. During adjustment, rotating the adjustment sleeve 452 can control the compression stroke of the spring 451.
