[0033] The motor is fixedly mounted on the centering platform base directly or through a mounting frame, a driving pulley is arranged on the output shaft of the motor, a passive pulley is arranged on one end of the first lead screw and one end of the second lead screw, the driving pulley and the passive pulley are connected by a belt, so that the motor drives the two lead screws to rotate through the pulley and the belt.

[0034] The first screw nut seat is movably arranged on the first screw, and the motor drives the first screw to rotate, so that the first screw nut seat moves back and forth on the first screw.

[0035] The second screw nut seat is movably arranged on the second screw, and the motor drives the second screw nut to rotate, so that the second screw nut seat moves back and forth on the second screw nut.

[0036] The linear guide is arranged between the first lead screw and the second lead screw, and the first nut seat and the second nut seat are movably connected to the linear guide via a slider, so that the first nut seat and the second nut seat can perform relative reciprocating motion along the linear guide.

[0037] An anti-collision block for limiting position is arranged on the nut seat and / or the sliding block to prevent the first nut seat and the second nut seat from colliding when they move toward the middle.

[0038] A first beating rod is arranged on the first nut seat. The first beating rod can be fixedly arranged on the nut seat or movably arranged on the nut seat. However, the top of the first beating rod must be located above the panel so that the first beating rod is always in a working state to limit the lateral outer side of the product plate.

[0039] A beating rod copper sleeve and a beating rod cylinder are provided on the second nut seat. The lower end of the second beating rod passes through the beating rod copper sleeve and is connected to the output end of the beating rod cylinder. The beating rod cylinder drives the second beating rod to move up and down along the guide copper sleeve, so that the top of the second beating rod passes through the panel or retracts to under the panel.

[0043] The beating rod cylinder shrinks, the second beating rod on the inside is retracted under the panel, the detection switch cylinder shrinks, and the material detection does not work;

[0044] One of the motors in the two bidirectional centering units works to drive the first lead screws in the two units to rotate, so that the two first screw nuts drive the first beating rods to move horizontally toward the middle. At this time, the two beating rods can realize horizontal centering of a single large sheet on the panel;

[0045] According to the horizontal length of the plate, a corresponding number of driving motors are turned on to drive the third screw to rotate, so that the third nut drives the third beating rod to move longitudinally to the middle.
