The bottom of the fixing block 256 is fixedly connected to the upper surface of the movable plate 26, and the rear end of the threaded rod 251 rotates to extend the corresponding fixing plate 252 and is connected to a hand wheel 250. A positioning head is provided on the front end fixing plate 252. The positioning head includes a connecting plate 255, a positioning cylinder is provided at the bottom of the connecting plate 255, a mounting plate 257 is connected to the end of the positioning cylinder, and a positioning block 258 in contact with the side wall of the tempered glass 2 is fixed to the bottom of the mounting plate 257; the threaded rod 251 can be rotated by the handwheel 250, so that the two sliding rods 254 slide in the fixing sleeve 253, thereby driving the fixing plate 252 and the sliding rod 254 to move forward and backward at the same time, and then the connecting plate 255, the positioning cylinder, the mounting plate 257, and the positioning block 258 can be moved forward and backward at the same time, so that the optimal fixing position of the tempered glass 2 can be adjusted.

[0031] The connecting plate 255 on one side of the tempered glass 2 is L-shaped, and the positioning cylinder is located at the horizontal part of the L-shaped connecting plate 255 to facilitate positioning and fixing one side of the tempered glass 2.

[0032] An edging mechanism is provided on the right side of the loading workbench 1; the edging mechanism includes, from top to bottom, a turntable 19 connected in sequence, an edging workbench 18 fixed to the turntable 19, and a suction cup assembly; a frame 2 10 perpendicular to the frame 1 9 is provided above the suction cup assembly and at the rear side of the frame 1 9; a grinding disc assembly is slidably provided at the bottom of the frame 2 10; the grinding disc assembly includes an edging cylinder 12 hoisted on the frame 2 10, a sliding block 11 connected to the telescopic end of the edging cylinder 12, and a grinding block 13 connected to the bottom of the sliding block 11; the top of the sliding block 11 is slidably connected to the frame 2 10; a grinding port 14 for accommodating the tempered glass 2 is opened on the front side of the grinding block 13; the turntable 19 drives the tempered glass 2 on the edging workbench 18 to rotate in the grinding port 14, thereby realizing the edging of the tempered glass 2. Driven by the edge grinding cylinder 12 , the sliding block 11 moves forward and backward along the frame 2 10 , and drives the grinding block 13 to move forward and backward together. The grinding block 13 is located at the rear side of the tempered glass 2 .

[0033] A rotating column 20 is fixed to the bottom of the turntable 19, and a fixed plate 21 is rotatably connected to the bottom of the rotating column 20. A mounting slot is defined on one side of the fixed plate 21, and a drive motor 22 is disposed within the mounting slot. A slave gear 24 is connected to the rotating column 20, and a master gear 23, which meshes with the slave gear 24, is fixedly connected to the output shaft of the drive motor 22. When the drive motor 22 is activated, the master gear 23 and the slave gear 24 engage, driving the rotating column 20 to rotate. This, in turn, rotates the turntable 19 and the edging table 18, allowing the tempered glass 2 on the positioning suction cup 15 to rotate 360° without blind spots, thereby achieving all-around edging of the tempered glass.

[0034] The sucker assembly comprises a plurality of support columns 16 and a positioning sucker 15 fixed on the top of the support columns 16 on the upper surface of the edging workbench 18.

A threaded hole is defined in the center of the mounting plate 17, which mates with the stud. The mounting plate 17 is threadedly mounted within the threaded hole. The combination of the threaded hole and the stud facilitates the installation and removal of the positioning suction cups 15. The number of positioning suction cups 15 that can be installed depends on the size of the tempered glass 2.

[0036] In the above embodiment, the movement of the movable plate 26 on the guide rail, the movement of the grabbing mechanism on the frame 1 9 , and the movement of the grinding disc assembly on the frame 2 10 are achieved by a linear motor.

[0037] The present invention's rapid edge grinding tool for automotive tempered glass 2 achieves efficient glass handling and processing through a meticulously designed mechanical structure. First, the tempered glass 2 to be edged is loaded and placed on the loading workbench 1, with its rear side wall contacting the positioning block 258 of the rear positioning device 25, and one side wall contacting the side positioning block 258. This allows the tempered glass 2 to be positioned optimally for grasping and prevents deviation. The threaded rod 251 adjustment mechanism on the movable plate 26 allows the user to precisely position the fixed plate 252 by rotating the handwheel 250, thereby determining the optimal position of the positioning block 258 and ensuring that the tempered glass 2 is firmly fixed in the ideal position, avoiding displacement and damage during processing. The ingenious design of the L-shaped connecting plate 255 and the positioning cylinder further enhances the stable positioning of the side edges of the tempered glass 2. Integration with the unique guide rail system provides a solid foundation for the entire operation. The gripping mechanism is mounted on frame 19, using a gripping cylinder 6 to drive the disc 5 up and down. The gripping rod 3 on the disc works in conjunction with the suction cup, precisely controlling the suction and release of the suction cup to flexibly grasp tempered glass 2 of varying sizes and adjust it to the optimal gripping position. This process is accomplished by manually or automatically adjusting the gripping mechanism's left and right sliding motion on frame 19. Entering the edging stage, the edging mechanism achieves rotational motion of the tempered glass 2 through the combination of the turntable 19 and the edging table 18. The grinding disc assembly retracts and retracts with the edging cylinder 12, and the grinding block 13 on it precisely grinds the edge of the rotating tempered glass 2 within the grinding opening 14. Power transmission from the drive motor 22 and the gear system ensures smooth, continuous 360° rotation of the turntable 19, making the edging operation comprehensive and efficient. The layout of the suction cup assembly through the support column 16 and the positioning suction cup 15 not only provides a stable processing platform for the tempered glass 2, but also realizes the possibility of flexibly adjusting the suction cup layout according to the size of the glass, thereby improving the versatility and adaptability of the equipment. A gripping mechanism similar to that above the positioning device 25 can be set on the right side of the edging device, thereby transferring the tempered glass 2 with the edge ground to the next process.
