[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-4This utility model provides a technical solution for a foreign object identification and detection device for Pu'er tea.
[0031] A foreign object identification and detection device for Pu'er tea includes:
[0032] Inspect chassis 1;
[0033] A flexible vibrating plate is installed on the detection base 1, and a material tray 3 is installed on the flexible vibrating plate. Tea leaves are installed inside the material tray 3.
[0034] The identification bracket 4 is fixed on the detection chassis 1. The identification camera 5 is fixed on the identification bracket 4. The identification camera 5 is located above the flexible vibrating plate and identifies foreign objects in the tea leaves.
[0035] When identification is required, the tray 3 containing tea leaves is placed on the flexible vibrating plate. The flexible vibrating plate vibrates once (which may be a few seconds) and then stops. An industrial camera (model ACA2500-14GC) is used to photograph and detect whether there are foreign objects in the Pu'er tea in the tray 3 on the flexible vibrating plate. If no foreign objects are detected, the flexible vibrating plate vibrates a second time, and the industrial camera performs foreign object detection again. The vibration method disperses the tea leaves in the tray, which can increase the probability of foreign object detection.
[0036] In large-scale foreign object detection processes, the presence rate of foreign objects is relatively low. However, if foreign objects are mixed into the final packaged Pu'er tea product, it will have a significant impact on the company's reputation. Therefore, it is preferable to perform three vibrations and three tests to detect Pu'er tea containing foreign objects as accurately as possible.
[0037] The Y-axis recognition module 6 is fixed on the recognition bracket 4, and the recognition camera 5 is fixed on the Y-axis recognition module 6. The Y-axis recognition module 6 can drive the recognition camera 5 to move in the Y direction. There are two flexible vibrating disks, which are arranged in sequence along the Y-axis direction.
[0038] In this way, while the tea leaves in the tray 3 on one of the flexible vibrating plates are being tested, the tray 3 to be tested can be placed on another flexible vibrating plate in advance. After the previous tray 3 has been tested, the Y-axis recognition module 6 drives the recognition camera 5 to move above the tray 3 to be tested for testing, which can increase recognition efficiency and reduce the waiting time for feeding.
[0039] The foreign object detection equipment for Pu'er tea also includes:
[0040] The first pickup device 7 includes a first Y-axis module 8, a first Z-axis module 9, and a first suction device 10.

[0044] The material storage device holds the tray 3 to be tested, which is placed on the material storage device. The material storage device is used by the first picking device 7 and the second picking device 11 to pick up the tray 3 to be tested.
[0045] The first pickup device 7 can pick up the material tray 3 of the storage device and place it onto the first flexible vibrating plate 17, while the second pickup device 11 can pick up the material tray 3 of the storage device and place it onto the second flexible vibrating plate 18, thus enabling the loading of the material tray 3 to be inspected. When the material tray 3 placed on the first flexible vibrating plate 17 needs to be placed onto the second flexible vibrating plate 18 during inspection, the second X-axis module 16 drives the second flexible vibrating plate 18 to move to the right, and then the second pickup device 11 places the material tray 3 to be inspected onto the second flexible vibrating plate 18. Next, the second X-axis module 16 drives the second flexible vibrating plate 18 to move to the left to the inspection position. After the inspection of the material tray 3 placed on the first flexible vibrating plate 17 is completed, the recognition Y-axis module 6 moves the recognition camera 5 above the second flexible vibrating plate 18 for inspection, increasing inspection efficiency. One recognition camera 5 can achieve sequential inspection of the material trays 3 loaded onto the first flexible vibrating plate 17 and the second flexible vibrating plate 18.

[0049] The tray 3 to be tested is placed in the first position 21 of the first storage channel 20. Then, the storage push cylinder 23 drives the first push rod 26 to move. The first push rod 26 drives the tray 3 located in the first position 21 to move to the second position 22. This cycle is repeated so that multiple trays 3 to be tested can be stored in the first storage channel 20. The second picking device 11 can pick up the tray 3 located in the second position 22.
[0050] The upper side of the storage plate 19 is provided with a second storage channel 27, which extends along the X-axis.
