[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 4 The present invention provides a technical solution for Pu'er tea foreign body identification and detection equipment.

[0033] A Pu'er tea foreign body identification and detection device, comprising:

[0034] Detect chassis 1;

[0035] Flexible vibration plate, the flexible vibration plate is installed on the detection chassis 1, the material tray 3 is installed on the flexible vibration plate, and tea leaves are installed in the material tray 3;

[0036] The identification bracket 4 is fixed on the detection chassis 1. The identification bracket 4 is fixed with an identification camera 5. The identification camera 5 is located above the flexible vibration plate. The identification camera 5 identifies foreign matter in the tea leaves.

[0037] When identification is required, the tray 3 containing tea leaves is placed on the flexible vibrating tray. The flexible vibrating tray vibrates once (can be a few seconds) and then stops. The identification camera (model aca2500-14gc) is used to shoot and detect whether there are foreign objects in the Pu'er tea in the tray 3 on the flexible vibrating tray. If no foreign objects are identified, the flexible vibrating tray vibrates a second time, and the identification camera performs foreign object detection again. The vibration method is used to disperse the tea leaves in the tray, which can increase the probability of identifying foreign objects.

[0038] It is preferred to perform three vibrations and three tests so that Pu'er tea with foreign matter can be detected as much as possible.

[0039] An identification Y-axis module 6 is fixed on the identification bracket 4, and the identification camera 5 is fixed on the identification Y-axis module 6. The identification Y-axis module 6 can drive the identification camera 5 to move in the Y direction. Two flexible vibration disks are provided, and the two flexible vibration disks are arranged in sequence along the Y-axis direction.

[0040] In this way, when the tea leaves in the material tray 3 on one of the flexible vibration plates are being inspected, the material tray 3 to be inspected can be placed on another flexible vibration plate in advance. After the inspection of the previous material tray 3 is completed, the identification Y-axis module 6 drives the identification camera 5 to move to the top of the material tray 3 to be inspected for inspection, which can increase the recognition efficiency and reduce the waiting time for loading.

[0041] Pu'er tea foreign body identification and detection equipment also includes:

[0042] A first pickup device 7, which includes a first Y-axis module 8, a first Z-axis module 9, and a first suction device 10.

[0047] The first pickup device 7 can absorb the material tray 3 of the material storage device onto the first flexible vibration disk 17, and the second pickup device 11 can absorb the material tray 3 of the material storage device onto the second flexible vibration disk 18, thereby realizing the loading of the material tray 3 to be inspected. When the material tray 3 placed on the first flexible vibration disk 17 is in the inspection process, it is necessary to place the material tray 3 to be inspected on the second flexible vibration disk 18. At this time, the second X-axis module 16 drives the second flexible vibration disk 18 to move to the right, and then the second pickup device 11 places the material tray 3 to be inspected on the second flexible vibration disk 18. Then, the second X-axis module 16 drives the second flexible vibration disk 18 to move to the left to the inspection position. After the inspection of the material tray 3 placed on the first flexible vibration disk 17 is completed, the identification Y-axis module 6 drives the identification camera 5 to move to the top of the second flexible vibration disk 18 for inspection, which can increase the inspection efficiency. One identification camera 5 can realize the sequential inspection of the material tray 3 on the first flexible vibration disk 17 and the second flexible vibration disk 18.
