[0178] Step 2: Rotate the first turntable 200, and move the workpiece to the electrical testing mechanism 500 through the first material taking mechanism 220. If the test result is not qualified, go to Step 3.1; if the test result is qualified, go to Step 3.2;

As the third turntable 460 pivots, the workpiece successively reaches the third workstations 403 at different positions, and undergoes inkjet coding, top surface influence detection, and second bottom surface image detection respectively.

[0189] Different from Embodiment 1 of the present invention, in Embodiment 2 and Embodiment 3 of the present invention, the entire process is to first perform electrical detection, then perform initial bottom surface detection, then perform coding, and then perform subsequent six-sided detection, and finally perform packaging and collection. The entire process automatically performs electrical detection, surface and dimension detection, and inkjet coding process on the workpiece. While improving efficiency, since electrical detection is performed first and then surface detection, secondary damage to the workpiece during electrical detection can be avoided, and the yield is improved.

[0190] In Embodiment 1, Embodiment 2, and Embodiment 3 of the present invention, the feeding mechanism is a vibrating disk.

[0191] As a further optimization of the above Embodiment 1, Embodiment 2, and Embodiment 3, referring to Figures 6 to 7 , the positioning mechanism 700 includes a lifting seat 710, a base 720, a rotating seat 730, a clamping member 740, a driving member 750, a rotating wheel 743, and a reset member 760;

[0192] The lifting seat 710 is correspondingly arranged with the first workstation 210 and is fixed on the machine table 100. The top end of the lifting seat 710 is connected with a lifting rod 711, and the lifting seat 710 is used to push the lifting rod 711 to rise or fall;

[0193] The base 720 is located above the lifting seat 710, and a rotating hole 721 is penetrated through the middle of the base 720;

[0194] The rotating seat 730 is pivotally inserted into the rotating hole 721. A bearing platform 731 is arranged at the top of the rotating seat 730, a slot hole 732 is arranged at the bottom of the carrier, the bearing platform 731 overlaps on the base 720, four sliding grooves 733 are arranged at the edge of the bearing platform 731, the four sliding grooves 733 are equidistantly spaced around the center of the bearing platform 731, the sliding grooves 733 penetrate from the edge of the bearing platform 731 to the slot hole 732 along the radial direction, and the lifting rod 711 penetrates through the rotating seat 730 from bottom to top and extends into the hollow area of the rotating seat 730;

[0195] The clamping member 740 includes a sliding portion 741 and an abutting portion 742. The sliding portion 741 is built into the sliding groove 733 and is slidably connected to the sliding groove 733. The abutting portion 742 protrudes from the surface of the rotating seat 730. The sliding portion 741 slides to make the four abutting portions 742 approach or move away from the center of the slot hole 732.

[0196] The driving member 750 is conical. The driving member 750 is fixedly connected to the top end of the lifting rod 711 and is built into the slot hole 732.

[0197] The rotating wheel 743 is pivotally arranged on one side of the sliding portion 741 close to the center of the rotating seat 730.

[0198] The reset member 760 is arranged on the bearing table 731. The reset member 760 abuts against the outer side of the sliding portion 741 to drive the clamping member 740 to approach the middle part of the rotating seat 730.

[0199] Wherein, the lifting rod 711 can rise so that the driving member 750 abuts against the rotating wheel 743 and drives the clamping member 740 to move away from the middle part of the rotating seat 730.

[0200] Specifically, the positioning mechanism 700 of this embodiment has the following two functions:

[0201] 1. Through the cooperation of the four clamping members 740, the workpiece is clamped at the center of the surface of the bearing table 731.

[0202] 2. Through the rotation of the rotating seat 730 in the base 720, the workpiece is repositioned to adapt to the visual inspection mechanism 620 for side appearance defects at different installation positions.

[0203] Specifically, in function 1, the lifting seat 710 drives the lifting rod 711 to rise, so that the conical driving member 750 abuts against the four sliding portions 741 at the same time, causing the sliding portions 741 to slide outward and expanding the space between the abutting portions 742. After the workpiece is placed between the four clamping members 740, the lifting rod 711 is retracted, so that the sliding portions 741 can slide inward under the action of the reset member 760. Specifically, the reset member 760 is an elastic ring. The elastic ring wraps the four sliding portions 741. A groove for the elastic ring to be embedded is arranged on the outer side of the sliding portion 741, so that the entire clamping member 740 can move towards the central position and the workpiece is clamped by the clamping member 740.

[0204] Preferably, in order to further improve the clamping effect on the workpiece in Function 1, an air hole 7311 is provided through the center of the surface of the bearing table 731. An air guide groove 7111 is provided on the lifting rod 711 from top to bottom. An air port 7112 is provided on the side wall at the lower end of the lifting rod 711. One end of the air guide groove 7111 penetrates through the driving member 750, and the other end communicates with the air port 7112. Among them, the lifting rod 711 can rise so that the top surface of the driving member 750 abuts against the top surface of the slot hole 732, and the air guide groove 7111 communicates with the air hole 7311. The air port 7112 is connected with a flexible air pipe, and the flexible air pipe is connected with a vacuum pump. After the four clamping members 740 are expanded and the end of the driving member 750 abuts against the bearing table 731, the workpiece will not fall outside the positioning mechanism 700 through vacuum adsorption. When the driving member 750 leaves the bearing table 731 instantaneously, under the action of the resetting member 760, the clamping members 740 will contract instantaneously so that the workpiece is fixed on the bearing table 731 from beginning to end. In addition, due to the pre-positioning of vacuum adsorption, the workpiece can be clamped without the need for a greater instantaneous clamping force, avoiding damage to the surface of the workpiece caused by excessive instantaneous clamping force and further improving the yield rate.
