[0021] S1, upper crystal ring: the crystal ring loaded with lamp beads is placed in the feeding mechanism by an external feeding device or an operator, and the crystal ring without lamp beads is placed in the material collecting mechanism; after the feeding mechanism and the material collecting mechanism sense the material, they move to the material taking position; after the feeding mechanism is in place, the first crystal ring transverse moving mechanism takes the material and moves the crystal ring loaded with lamp beads to the corresponding crystal ring workbench on the same side; meanwhile, after the material collecting mechanism is in place, the second crystal ring transverse moving mechanism takes the material and moves the empty crystal ring to the corresponding crystal ring workbench on the same side;

[0022] S2, upper lamp bead: the crystal ring loaded with lamp beads is adjusted in rotation and correctly enters the clamping position under the action of the crystal ring workbench corresponding to the first crystal ring transverse moving mechanism; meanwhile, the crystal ring workbench fixes the crystal ring loaded with lamp beads; after being fixed, the crystal ring loaded with lamp beads is moved to the corresponding lamp bead positioning mechanism for positioning; after positioning is completed, the lamp bead taking and placing mechanism moves the lamp bead on the crystal ring to the lamp bead taking and placing station of the white card test mechanism;

[0069] In this step, the actions of the feeding mechanism 500 and the collecting mechanism 800 are as follows: after the host computer receives the feeding information, the PLC controller corresponding to the feeding mechanism 500 and the collecting mechanism 800 is instructed, the feeding driving device 502 and the collecting driving device are controlled to act, thereby driving the liftable feeding box 501 and the liftable collecting box to move upward to the position for taking the material, and then the PLC controller controls the feeding driving device 502 and the collecting driving device to stop acting;

[0070] When the liftable feeding box 501 and the liftable collecting box reach the position for taking the material, the crystal ring inductor 603 on the first crystal ring transverse moving mechanism 600 and the second crystal ring transverse moving mechanism 900 senses the feeding and feeds the feeding information back to the host computer, the host computer instructs the corresponding PLC controller to control the transverse moving motor 602 to act, under the driving of the transverse moving motor 602, the clamping jaw cylinder 601 moves to the direction of the box until above the box, the clamping jaw cylinder 601 acts to drive the clamping jaw to clamp the crystal ring in the corresponding box, and finally the corresponding crystal ring is placed in the crystal ring workbench 700 on the same side;

After the feeding mechanism and the collecting mechanism are sensed, they are moved to the material taking position. After the feeding mechanism is in place, the first crystal ring transverse moving mechanism takes the material, and moves the crystal ring loaded with lamp beads to the corresponding crystal ring workbench on the same side. At the same time, after the collecting mechanism is in place, the second crystal ring transverse moving mechanism takes the material, and moves the empty crystal ring to the corresponding crystal ring workbench on the same side; S2, loading lamp beads: the crystal ring loaded with lamp beads is adjusted in rotation under the action of the crystal ring workbench corresponding to the first crystal ring transverse moving mechanism, and correctly enters the clamping position. At the same time, the crystal ring workbench fixes the crystal ring loaded with lamp beads. After being fixed, the crystal ring loaded with lamp beads is moved to the corresponding lamp bead positioning mechanism for positioning. After positioning is completed, the lamp bead taking and placing mechanism moves the lamp bead on the crystal ring to the lamp bead taking and placing station of the white card testing mechanism; S3, white card testing: after the lamp bead is in place, the disc turntable drives the lamp bead to rotate to the lower side of the code scanning head, the code scanning head reads the two-dimensional code information on the lamp bead and uploads it to the test computer. After the code scanning is completed, the disc turntable continues to rotate, so that the lamp bead rotates to the lamp bead testing device. The lamp bead testing device fixes and lights the lamp bead. At this time, the electric conductivity parameter at the bottom of the lamp bead is uploaded to the test computer through the lamp bead testing device. At this time, the funnel located above the lamp bead collects the light emitted by the lamp bead and makes it irradiate on the test card. The test card transmits the light parameter exhibited by the lamp bead to the test computer. The test computer compares the electric conductivity parameter and the light parameter with the preset standard to determine whether the lamp bead is NG or OK material. At this time, the disc turntable continues to rotate. If the lamp bead is NG material, the NG material box is blown into the NG material box by the NG material box when the lamp bead reaches the NG material box. If the lamp bead is OK material, the NG material box does not act, so that the lamp bead continues to rotate with the disc turntable until the separation device, the separation device lifts the lamp bead to make it separate from the disc turntable, and enters the straight vibration track mechanism; S4, straight vibration conveying: the lamp bead enters the straight vibration track and moves from the white card testing mechanism to the gray card testing mechanism under the action of the straight vibration head; S5, gray card testing: the overall test action is similar to step S3 white card testing, and the difference is that the movement direction of the lamp bead is from the separation device of the gray card testing mechanism to the lamp bead taking and placing station of the gray card testing mechanism, which is opposite to the movement direction of the lamp bead in the white card testing mechanism; S6, lamp bead collection: the OK lamp bead after the gray card testing mechanism moves to the lamp bead taking and placing station of the gray card testing mechanism. At this time, the lamp bead taking and placing mechanism on the same side moves the tested lamp bead to the empty crystal ring of the crystal ring workbench on the same side which is previously in place. S7, crystal ring recycling: the crystal ring with the tested lamp bead on the side corresponding to the gray card testing mechanism moves to the material collecting mechanism under the action of the second crystal ring transverse movement mechanism, and the empty crystal ring on the side corresponding to the white card testing mechanism returns to the material feeding mechanism under the action of the first crystal ring transverse movement mechanism, to complete a cycle. After the external material collecting device or the operator collects the material, the next cycle is performed.
