Description

Technical Field

[0001] The utility model relates to the technical field of glass detection, in particular to a glass magnetic grating edge measuring device. Background Art

[0002] After cutting and before being made into corresponding products, the glass needs to be edged. Before edge grinding, the length, width and other data of the glass need to be detected. Although the glass detection mechanism used in traditional glass edge grinding machines can measure thickness during use, it can only detect thickness during use. It cannot measure the length and width of glass plates of different sizes during use, resulting in the need to use a tape measure to measure the tempered glass plate again during processing. In addition, it lacks the function of detecting the tempered glass plate during use, and the tempered glass plate needs to be measured again during use, resulting in poor overall functionality.

[0003] Although the existing improved glass edge measuring mechanism can also measure data such as length and width, its accuracy is not high. The reliability of the synchronous belt combined with the servo motor solution is not high, which reduces the edge grinding quality and accuracy. It also has many wires and cables, which interfere with the robot's grasping of the glass. Therefore, a high-reliability and high-precision glass edge measuring device is needed.

[0022] A parallel connecting rod 4 is provided below the ball slide rail 9, one end of the connecting rod 4 is connected to the ball slider 3, and the other end of the connecting rod 4 is connected to the end of the magnetic grid rod 2 through a connecting piece 6; one end of the connecting rod 4 is fixed to the bottom of the ball slider 3 by bolts, and the connecting piece 6 is arranged perpendicular to the connecting rod 4.

[0023] A connecting plate is vertically connected to one end of the connecting rod 4 , and a photoelectric switch 5 is arranged on the connecting plate. The photoelectric switch 5 is arranged below the connecting piece 6 .

The connecting rod 4 moves linearly along the slide rail 9 through the ball slider 3, and the connecting rod 4 drives the photoelectric switch 5 to follow the movement; when the photoelectric switch 5 is triggered (generally when the edge of the glass is detected), the feedback signal is given to the PLC to trigger an interrupt.
