[0009] As a further description of the above technical solution: a strip-shaped opening is provided on the top surface of the support frame through the support shell, and a clearance opening is provided at the bottom of the support shell corresponding to the positioning sleeve.

[0010] As a further description of the above technical solution: U-shaped guide grooves are provided on both sides of the movable seat, the cross section of the guide plate is arranged in a T-shaped structure with respect to the guide groove, and the guide plate is slidably connected to the guide groove of the movable seat.

By arranging two groups of moving clamps and fixed clamps on the carrier plate, the cylinder in the extended state is started to contract, so that the cylinder drives the moving clamps to approach the fixed clamps under the action of the mounting block, so that the moving clamps and the fixed clamps are connected with the edge of the tempered glass by rubber pads. The two surfaces at the edge are abutted against each other to achieve the purpose of clamping the tempered glass. Since a comb-tooth type movable clamping plate is adopted and the fixed clamping plates are arranged in groups of two, the contact area with the tempered glass can be reduced to the greatest extent, which is beneficial to the cleaning of the tempered glass. At the same time, since two distance sensors are arranged at both ends of the support frame corresponding to the moving track of the moving seat, when the distance sensor distance between the moving seat and the left or right end of the support frame reaches the preset value range, the PLC controller cuts off the power supply of the servo motor, which provides a basis for the automatic taking, placing and position transfer of the tempered glass, and facilitates the transfer of the tempered glass between the two processes.
