[0043] In this embodiment, there are two workpiece baffles 121, which are fixedly mounted on the workpiece carrier 120 and are perpendicular to each other. At the same time, the ends of the two workpiece baffles 121 that are away from each other are relatively close to the side of the top plate 110. When the workpiece is placed on the workpiece carrier 120, it can automatically slide down due to gravity and fit against the two workpiece baffles 121, thereby completing self-positioning.

[0044] In this embodiment, a thickness detection mechanism is also provided on the top plate 110; before the robot places the workpiece on the workpiece carrier 120, the thickness of the workpiece can be detected by the thickness detection mechanism to ensure that the thickness meets the requirements before placing it on the workpiece carrier 120.

[0045] In a preferred embodiment, the workpiece baffle 121 is fitted and installed on the workpiece carrier plate 120 and fixedly connected to the workpiece carrier plate 120; the thickness of the workpiece baffle 121 is relatively smaller than the thickness of the workpiece, and is used for the manipulator to pick up.

[0046] In this embodiment, the thickness of the workpiece baffle 121 is relatively smaller than the thickness of the workpiece, and it is in close contact and fixedly connected to the workpiece baffle 121; when the workpiece is positioned in close contact with the workpiece baffle 121 and the workpiece carrier plate 120, the thickness difference can also be used for the manipulator to pick up.

[0047] In a preferred embodiment, a proximity sensor 122 is further provided on the workpiece carrier plate 120; the proximity sensor 122 is installed on the side of the workpiece carrier plate 120 away from the workpiece baffle 121 and at one end where the two workpiece baffles 121 are relatively close to each other, and is used to detect the position of the workpiece.

[0048] In this embodiment, the proximity sensor 122 is installed at the included angle of the two workpiece baffles 121. When the workpiece is in the positioning position with the workpiece carrier plate 120 and the workpiece baffle 121, the proximity sensor 122 will be triggered, so that the manipulator can continue to complete the subsequent actions.

[0049] In a preferred embodiment, an air channel is provided inside the workpiece baffle 121 along the length direction; air holes communicating with the air channel are provided on one side of the two workpiece baffles 121 close to each other, and are used to clean the bottom surface of the workpiece; one end of the two workpiece baffles 121 close to each other is installed at intervals to form a chip discharge groove.
