[0117] The base 720 is located above the lifting seat 710, and a rotating hole is provided through the middle of the base 720;

[0118] The rotating seat 730 is pivotally inserted into the rotating hole. The top of the rotating seat 730 is provided with a support platform 731, and the bottom of the support platform 731 is provided with a slot 732. The support platform 731 overlaps the base 720. The edge of the support platform 731 is provided with four sliding grooves 733. The four sliding grooves 733 are equidistantly spaced around the center of the support platform 731. The sliding grooves 733 extend from the edge of the support platform 731 along the radial direction to the slot 732. The lifting rod 711 passes through the rotating seat 730 from bottom to top and extends into the hollow area of ​​the rotating seat 730.

[0119] The clamping member 740 includes a sliding part 741 and an abutting part 742. The sliding part 741 is built into the slide groove 733 and is slidably connected to the slide groove 733. The abutting part 742 protrudes from the surface of the rotating seat 730. The sliding part 741 slides so that the four abutting parts 742 are close to or away from the center of the slot 732.

[0120] The drive component 750 is conical and is fixedly connected to the top of the lifting rod 711 and is built into the slot 732.

[0121] The rotating wheel 743 is pivotally disposed on the side of the sliding part 741 near the center of the rotating seat 730;

[0122] The reset member 760 is disposed on the support platform 731, and the reset member 760 abuts against the outer side of the sliding part 741 to drive the clamping member 740 closer to the center of the rotating seat 730.

[0123] The lifting rod 711 can rise so that the driving member 750 and the rotating wheel 743 come into contact, and drive the clamping member 740 away from the center of the rotating seat 730.

[0124] Specifically, the positioning mechanism 700 in this embodiment has the following two functions:

[0125] 1. The workpiece is clamped to the center of the surface of the support table 731 by the cooperation of four clamping parts 740;

[0126] 2. The workpiece is repositioned by rotating the rotating seat 730 in the center of the base 720 to adapt to the side appearance defect visual inspection mechanism 620 in different installation positions;

[0127] Specifically, in function 1, the lifting seat 710 drives the lifting rod 711 to rise, causing the conical driving member 750 to simultaneously abut against the four sliding parts 741, causing the sliding parts 741 to slide outward and expanding the space between the abutting parts 742. After the workpiece is placed between the four clamping members 740, the lifting rod 711 retracts, allowing the sliding parts 741 to slide inward under the action of the reset member 760. Specifically, the reset member 760 is an elastic ring that wraps around the four sliding parts 741. The outer side of the sliding parts 741 is provided with a groove for the elastic ring to be inserted, so that the entire clamping member 740 can move towards the center position and clamp the workpiece using the clamping member 740.

[0128] In order to achieve function 2, the positioning mechanism 700 also includes a drive motor 770. The output shaft of the drive motor 770 is fixedly connected to a first pulley 771, and the lower end of the rotating seat 730 is fixedly connected to a second pulley 772. The second pulley 772 and the rotating seat 730 are coaxial, and a transmission belt 773 is wound between the first pulley 771 and the second pulley 772.

[0129] In some embodiments, both the first material handling mechanism 220 and the second material handling mechanism 320 are vacuum nozzles. This avoids damage to the workpiece surface.
