[0051] The transfer mechanism 81 is provided with an upper feeding structure 82 and a lower feeding structure 83 opposite to the upper and lower feeding assembly 92.

[0052] The transfer mechanism 81 is provided with an upper feeding structure 82 and a lower feeding structure 83 opposite to the scanning mechanism 9, so that the material is delivered to the scanning mechanism 9 under the action of the upper feeding structure 82, and after the scanning and detection are completed, the material can be delivered back to other test processing mechanisms by the lower feeding structure 83. The docking mechanism 8 can be used for quickly receiving other mechanisms and serving as a transfer for other mechanisms, which can ensure the processing rate of the whole machine. The scanning mechanism 9 is provided with the positioning guide rail 91 and the upper and lower feeding assembly 92 in order to cooperate with the upper feeding structure 82 and the lower feeding structure 83.

[0053] In a possible embodiment, the upper feeding structure 82 and the lower feeding structure 83 are arranged side by side, and the two structures are provided with guide rails and clamps. The terminals of the clamps correspond to different positions of the docking guide rail. The scanning mechanism 9 can feed the material placed on one side of the docking guide rail to the scanning and detection position of the scanning mechanism 9 through the upper and lower feeding assembly 92. After the detection is completed, the material can be delivered to the docking position of the lower feeding structure 83 through the upper and lower feeding assembly 92, so that the material can be quickly detected.

[0054] For reference Figures 7 to 8 The upper feeding structure 82 and the lower feeding structure 83 are arranged in a vertical direction. The transfer mechanism 81 is provided with an adjusting mechanism 84 opposite to the upper feeding structure 82 and the lower feeding structure 83.

[0055] The adjusting mechanism 84 comprises a moving structure 85, a lifting structure 86 and a clamping structure 87. The moving structure 85 is arranged along the extension direction of the feeding structure 82. The bottom of the lifting structure 86 is connected to the moving structure 85. The lifting structure 86 is drivingly connected to the clamping structure 87. The clamping structure 87 is connected to the alignment guide rail 91.

[0056] In another possible embodiment, the feeding structure 82 and the discharging structure 83 are arranged in a vertical manner. The end of the feeding structure 82 and the discharging structure 83 is provided with the adjusting mechanism 84. The adjusting mechanism 84 can be moved along the driving direction of the feeding structure 82 and the discharging structure 83 through the moving structure 85. The clamping structure 87 in the adjusting mechanism 84 can be moved up and down under the action of the lifting structure 86. The alignment guide rail 91 can be below the feeding structure 82 and the discharging structure 83. Under the cooperation of the adjusting mechanism 84, the material can be efficiently and stably sent to the alignment guide rail 91. After the code scanning detection is completed, the material can be quickly recovered. The rate of the entire test process can be effectively improved.

In order to enable the adjusting mechanism 84 to stably supply and take the material, the structure of the feeding and discharging assembly 92 can comprise a feeding structure and a discharging structure. The clamping structure 87 is between the alignment guide rail and the feeding structure. The feeding structure is generally arranged on the machine table and faces the alignment guide rail 91. The feeding push rod of the feeding structure can push the material into the alignment guide rail 91 through the clamping cavity of the clamping structure 87. After the test is completed, the discharging push rod of the discharging structure can push the material back into the clamping cavity of the clamping structure 87, so that the material can be conveniently transferred to the discharging structure 83 for discharging.

[0060] In order to improve the test efficiency, the moving object in the feeding and discharging structure 83 is generally a receiving frame. A plurality of separation layers are arranged in the frame. Each separation layer is provided with a material / tray. The clamping structure 87 can clamp the outer periphery of the frame and move up and down along the alignment guide rail 91 under the action of the lifting structure 86. When the separation layer in the frame faces the alignment guide rail 91, the feeding push rod drives the material / tray to enter the code scanning mechanism 9 for code scanning detection. After the detection is completed, the material / tray is pushed back into the separation layer by the discharging push rod. The lifting structure 86 is raised / lowered to make another separation layer face the alignment guide rail 91. Through this structure, the test efficiency can be effectively improved and the stability of the material conveying can be ensured.

The moving mechanism 16 itself can be a swing arm structure and is provided with two clamping jaws relative to the three stations of the first collecting assembly, the second collecting assembly, and the visual detection assembly 14. Through the swing arm structure, the materials can be first transferred from the visual detection assembly 14 to the first collecting assembly. If the materials need to be transferred to the second collecting assembly, the other clamping jaw will synchronously transfer the materials when taking the materials next time. Through the above structure, the height integration of the whole machine can be effectively guaranteed.

[0066] The moving mechanism 16 can also be two clamping jaws with lifting function running synchronously on the guide rail, which can have the same function as the swing arm structure and effectively improve the space utilization of the machine and guarantee the recycling efficiency of defective products.

[0075] The transfer mechanism 5 can be provided with a driving motor on each side, and the two driving motors can drive a suction cup or a clamping jaw for transferring material or a disc, respectively. The two suction cups or clamping jaws can be independently controlled, which can effectively guarantee the feeding rate of the empty disc, and the suction cups or clamping jaws on both sides can share a moving track, which can realize the reduction of the volume of the whole machine and effectively improve the user experience.

[0076] In combination with the drawings, Figures 3 to 6 The conveying mechanism 4 comprises a recovery support 41, a docking assembly 42 arranged on one side of the recovery support 41 and used for driving the recovery support 41 to ascend and descend, a conveying track 43 arranged on the other side of the recovery support 41 and along the conveying direction of the second guide rail 31, and a recovery frame 44 arranged in the recovery support 41 and connected to the conveying track 43. At least two disc feeding tracks are arranged in the vertical direction at the end of the recovery support 41 away from the second guide rail 31.

[0077] The conveying mechanism 4 is used for recovering the disc after the material is taken out. The conveying mechanism 4 itself comprises the recovery support 41, which can be adjusted in height by the docking assembly 42. The conveying track 43 is arranged in the recovery support 41, and the recovery frame 44 with a plurality of partition layers arranged in the vertical direction can be connected in the conveying track 43. Under the action of the docking assembly 42, different partitions can be connected to the second guide rail 31 in turn. When the recovery frame 44 is stacked and filled with empty discs, the conveying track 43 will convey the recovery frame 44 to the disc feeding track connected to the other side of the conveying mechanism 4.

[0078] The disc feeding tracks can be arranged in the vertical direction. Different disc feeding tracks can be aligned with the recovery frame 44 and the corresponding disc feeding track under the action of the docking assembly 42. Different disc feeding tracks can be connected to different mechanisms, which can help to improve the linkage of the whole machine and the degree of automation of the whole machine. In addition, a conveying mechanism 4 with the same structure as the present application can also be connected to the end of the feeding mechanism 1 for efficient feeding. Through the above structure, the integration of the whole machine can be improved, the detection efficiency of the machine body can be effectively improved, the quality of the discharged material can be guaranteed, and the user experience can be effectively improved.
