[0031] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0032] Embodiment 1:

[0033] like Figure 1 It is a structural schematic diagram of the utility model, a flower basket induction assembly, characterized in that it includes a fixing part 1, a movable rod 2, a sensor 3 and a contact block 4. The fixing part 1 is a PPN pressure basket induction fixing part. The fixing part 1 is used to connect with a mechanical claw hand. The fixing part 1 has a through hole 11 for the movable rod 2 to move up and down. The movable rod 2 is slidably arranged in the through hole 11 of the fixing part 1. The sensor 3 is installed on the fixing part 1. The movable rod 2 is in a falling state in the through hole 11 by its own weight, that is, the bottom surface of the top screw 7 is in contact with the top surface of the fixing part 1.

[0034] like Figure 3 As shown, the contact block 4 is used to contact with the flower basket and drive the movable rod 2 to move. The contact block 4 is a PTFE contact block. The contact block 4 and the movable rod 2 are threadedly connected. The contact block 4 is installed at the lower end of the movable rod 2. The contact block 4 is used to contact with the flower basket. The bottom surface of the contact block 4 is a contact surface 41. The contact surface 41 is a plane. By setting the contact surface 41 of the contact block 4 as a plane, it can achieve surface contact with the flower basket, and there is more contact area. On the one hand, it can avoid the misalignment of the contact block 4 and the flower basket. On the other hand, it can avoid the jamming of the movable rod 2 with the induction member 21, thereby greatly improving the accuracy of the induction assembly detection.

[0035] The movable rod 2 has a sensing element 21 for the sensor 3 to sense, and the sensor 3 is used to sense the sensing element 21 and provide feedback signals to the gripper;

[0036] In the initial state, the sensing element 21 is located below the sensor 3 .

[0037] The sensor 3 is a metal induction sensor, which is used to detect whether the induction member 21 of the movable rod 2 moves to the height of the metal induction sensor, and its detection result is more accurate;

[0038] The movable rod 2 includes a first non-metallic section 22 and a second non-metallic section 23. The first non-metallic section 21 is a glass solder rod, and the second non-metallic section 23 is a PPN connector. The induction member 21 is a columnar metal structure, and the induction member 21 is located between the first non-metallic section 22 and the second non-metallic section 23.

The shell 24 covers the outside of the first non-metallic section 22, the sensor 21 and the second non-metallic section 23, so that the first non-metallic section 22, the sensor 21 and the second non-metallic section 23 form a whole.

[0041] The movable rod 2 also includes a limit joint 5, the diameter of the limit joint 5 is larger than the diameter of the through hole 11, the limit joint 5 is installed at the upper end of the first non-metallic section 22, and the limit joint 5 is located above the fixing member 1. The limit joint 5 can prevent the movable rod 2 from slipping off the through hole 11 of the fixing member 1, and can also play a limiting role.

The anti-corrosion joint 6 is made of PVC. The anti-corrosion joint 6 can cover the sensor 3 and provide protection for the sensor 3 to reduce its corrosion by the external environment.

[0043] A top screw 7 for resisting the sensor 3 is installed on the anti-corrosion joint 6. The top screw 7 is made of PEEK. The top screw 7 can help fix the sensor 3 to prevent the sensor 3 from falling off from the anti-corrosion joint 6. The anti-corrosion joint 6 and the sensor 3 are threadedly connected.

[0044] When in use, the flower basket sensing assembly is installed on the manipulator and descends with the manipulator until the contact surface 41 of the contact block 4 of the flower basket sensing assembly touches the flower basket, so that the movable rod 2 as a whole moves upward relative to the fixing part 1 until the upper end of the sensing part 21 reaches the sensor 3 and is detected by the sensor 3. At this time, the sensor 3 sends a signal to drive the manipulator to grab the flower basket, and monitors in real time whether the flower basket falls during the transportation process.

[0054] like Figure 5 As shown, the first non-metallic section 22 and the sensing member 21 are connected by threads, a threaded column is protruded on the bottom surface of the first non-metallic section 22, and a threaded groove matching the threaded column is formed on the top surface of the sensing member 21, and the threaded column is installed in the threaded groove;

[0055] The induction member 21 and the second non-metallic section 23 are connected via threads, and the bottom surface of the induction member 21 may have a thread groove or a thread column.
