After contacting the rear limiting post 45, the glass substrate stops moving back and forth. Simultaneously, rotating wheel 472 continues to revolve. The rotating wheel 472, in contact with the glass substrate, experiences a reaction force from the glass substrate, causing it to rotate in the opposite direction to the rotation of shaft 46. Rotating wheel 472 exerts forward and leftward forces on the glass substrate.

[0024] It also includes a controller 5, which is located on the front side of bracket 1, and the input terminal of the controller 5 is electrically connected to an external power source.
[0025] The working principle of the gripping mechanism for glass substrate processing provided by this utility model is as follows: During installation, rotating wheels 472 are installed through corresponding left and right limit seats 474. Positioning seats 473 fix the distance between the right mounting plate 471 and the left mounting plate 475. Fixing bolts 477 fix the mounting plates 471 and 475. The rotating shaft 46 passes through the fixing sleeve 476 and is fixed by bolts. The glass substrate is conveyed to the upper end of the second bracket 2 by a conveyor belt. The output shaft of the motor 42 drives the pulley 41 to rotate. Through the belt transmission, the pulley 48 and the rotating shaft 46 in the middle rotate. The synchronous pulley 44 at the left end of the rotating shaft 46 in the middle rotates. Through the synchronous belt transmission, all the rotating shafts 46 rotate in the same direction. The whole assembly consisting of the right mounting plate 471, rotating wheels 472 and left mounting plate 475 rotates. The glass substrate is gripped by the right mounting plate. The entire assembly consisting of 471, rotating wheel 472, and left mounting plate 475 moves towards the rear of bracket 2. After contacting the rear limiting post 45, the glass substrate stops moving back and forth. At the same time, rotating wheel 472 continues to revolve. The rotating wheel 472 in contact with the glass substrate is subjected to the reaction force of the glass substrate and rotates in the opposite direction to the rotation of the rotating shaft 46. The rotating wheel 472 gives the glass substrate forward and leftward forces. The forward force cancels out the reaction force of the glass substrate, and the leftward force drives the glass substrate to move to the left until it contacts the left limiting seat 474, achieving automatic alignment. Then, the telescopic end of the electric push rod 34 extends, the vacuum suction cup 36 descends to grab the glass substrate, and the linear guide rail 33 drives the electric push rod 34 and the glass substrate to move at the lower end of the linear guide rail 33. The rotating table 31 drives the support frame 32 to rotate, realizing the repositioning of the glass substrate.
