At this time, the sample falls to the top of the sponge cushion pad for collection. The setting of the buffer structure in the sample box can reduce damage to the sample and improve the reliability of the result. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Among them, by setting up the sampling component 8, an automatic sampling device is formed, which can perform uniform time sampling and detection on the items on the conveyor belt 2, avoiding the subjective selection error caused by manual sampling, thereby ensuring the randomness of sample extraction, thereby ensuring the representativeness and reliability of the quality inspection sampling data. When sampling, the first motor 801 and the second motor 808 are turned on, and the first motor 801 drives the bevel gear rod 802 to rotate. When the bevel gear rod 802 rotates, the rotating rod 803 is driven to rotate through the bevel gear part 804. When the rotating rod 803 rotates The strip 805 is driven to rotate. When in the sampling area, the second motor 808 at the top of the strip 805 drives the lead screw 809 to rotate, so that the moving part 810 moves along the lead screw 809, which can increase the sampling range, so that each component on the top of the conveyor belt 2 has the possibility of being randomly selected, and then the hydraulic rod 811 is controlled to extend.

The automatic sampling can be performed without supervision, which greatly improves the sampling efficiency and reduces the labor cost. Before sampling, the parts are conveyed by the conveyor belt 2 and conveyed to the paving assembly 4 so that the paving assembly 4 performs a paving operation on the parts to prevent the parts from being stacked and causing the reliability of the sampling results to be reduced, so that each sample has the same probability of being drawn.

Then, when passing through the sample box 7, the hydraulic rod 811 is controlled to extend, and at the same time, the circuit element 813 is controlled to make the electromagnet 814 de-energized and lose its magnetism. At this time, the sample falls to the top of the sponge cushion pad 702 for collection. The setting of the buffer structure in the sample box 7 can reduce damage to the sample and improve the reliability of the result. When sampling, the first motor 801 and the second motor 808 are turned on, and the first motor 801 drives the bevel gear rod 802 to rotate. When the bevel gear rod 802 rotates, it drives the rotating rod 803 to rotate through the bevel gear part 804. When the rotating rod 803 rotates, it drives the long strip 805 to rotate. When in the sampling area, the second motor 808 at the top of the long strip 805 drives the screw rod 809 to rotate, so that the moving part 810 moves along the screw rod 809, which can increase the sampling range, so that each component at the top of the conveyor belt 2 has the possibility of being randomly selected, and then the hydraulic rod 811 is controlled to extend. At this time, under the action of the circuit element 813, the electromagnet 814 is energized and has adsorption properties, so as to adsorb the components, thereby realizing the random sampling process.
