[0051] Optionally, the upper surface of the support wheels 122 is higher than the upper surface of the support plate 121 to prevent the support plate 121 from contacting the surface of the workpiece.

[0052] Optionally, the outer surface of the support wheels 122 is made of rubber.

[0053] Optionally, there are three support components 12 to stably support the workpiece.

[0057] Optionally, the first positioning post 131 is provided on the front side of the tray 111, and the second positioning post 132 is correspondingly provided on the rear side of the tray 111. When the first positioning post 131 and the second positioning post 132 are in the initial position, they cannot contact the workpiece. When the first positioning post 131 and the second positioning post 132 abut against the workpiece, they can only contact the side surface of the workpiece. Therefore, no scratches or damages will be caused to the surface of the workpiece.

[0067] Optionally, when the workpiece is transported to the pallet assembly 11 by the transport assembly 14, the transport assembly 14 stops transporting. Then, the support assembly 12 rises until the support wheel 122 abuts against the workpiece. The support assembly 12 drives the workpiece to continue rising until the support wheel 122 reaches the first preset position. The support assembly 12 stops rising. Next, the first positioning post 131 and the second positioning post 132 move towards the workpiece until both the first positioning post 131 and the second positioning post 132 abut against the workpiece. At this time, the center positioning of the workpiece is completed. Then, the first positioning post 131 and the second positioning post 132 move away from the workpiece to the initial position. The pallet assembly 11 rises until the support post 112 reaches the fourth preset position. The support assembly 12 descends until the workpiece invalid area thereon abuts against the support post 112. At this time, the workpiece can enter the next process. When the workpiece is taken away, the pallet assembly 11 descends to the original pallet position to prevent the support post 112 from accidentally contacting the surface of the workpiece. At the same time, the support assembly 12 also descends to the original support position for the next center positioning.

[0068] Optionally, when the thickness of the workpiece is relatively thin, in order to more stably support the workpiece and prevent the workpiece from deforming, after the center positioning of the workpiece is completed, the first lifting mechanism 113 drives the pallet 111 and the support post 112 to rise until the support post 112 abuts against the workpiece invalid area. Then, after the first positioning post 131 and the second positioning post 132 move away from the workpiece to the initial position, the support assembly 12 descends to the original support position. Next, the first lifting mechanism 113 drives the workpiece to descend until the support post 112 reaches the fourth preset position. At this time, the workpiece can enter the next process. When the workpiece is taken away, the pallet assembly 11 descends to the original pallet position to prevent the support post 112 from accidentally contacting the surface of the workpiece.

[0069] Optionally, in order to more accurately perform center positioning on the workpiece, after the first positioning post 131 reaches the second preset position at the first moving speed, the moving speed changes to the third moving speed until the first positioning post 131 abuts against the workpiece, where the third moving speed is less than the first moving speed. With such a setting, when the distance between the first positioning post 131 and the workpiece is relatively far, the movement can be completed with higher efficiency. When the distance between the first positioning post 131 and the workpiece is relatively close, the workpiece can be centered and positioned with higher precision.

[0070] Optionally, after the second positioning post 132 reaches the third preset position at the second moving speed, the moving speed changes to the fourth moving speed until the second positioning post 132 abuts against the workpiece, where the fourth moving speed is less than the second moving speed. With such a setting, when the distance between the second positioning post 132 and the workpiece is relatively far, the movement can be completed with higher efficiency. When the distance between the second positioning post 132 and the workpiece is relatively close, the workpiece can be centered and positioned with higher precision.

[0071] Optionally, the first moving speed is equal to the second moving speed, and the third moving speed is equal to the fourth moving speed.
