[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 , the present utility model provides a technical solution: A tube feeding assembly for tube-piston distribution and assembly includes a stocking component 1 and a feeding assembly 2. The feeding assembly 2 transports the tube 100 in the stocking component 1 to the assembly mechanism, and the assembly mechanism assembles the tube and the plug.

[0019] In an embodiment of the present utility model, the material placing assembly 1 includes a hopper 11, a hopper support 12, a hopper support seat 13, a runner 14 and a runner drive assembly 15. The hopper 11 is arranged on the hopper support 12. The hopper support seat 13 is arranged at the bottom of the hopper support 12. The runner 14 is arranged inside the hopper support 12. The hopper support 12 is provided with a pipe taking port 16. The circumferential surface of the runner 14 is provided with grooves 17 for placing pipe bodies. The grooves 17 are arranged horizontally. The runner drive assembly 15 drives the runner 14 to rotate. The hopper 11 is located above the runner 14. An inclined channel connecting the hopper 11 and the runner 14 is arranged inside the hopper support 12. When the pipe bodies are placed into the hopper 11, they will automatically enter the grooves 17 along the channel. Since multiple pipe bodies can be placed at one time, the pipe bodies that do not enter the grooves 17 will accumulate in the channel. The hopper support 12 is provided with an upper cover 19. The upper cover 19 is provided with an observation hole 191 along the inclined direction of the hopper support. A photoelectric sensor 192 is arranged at the upper end of the observation hole 191. As the runner 14 rotates, the pipe bodies in the channel will enter different grooves 17, and thus automatic material placing can be completed.

[0020] In this embodiment, please refer to Figure 2 , the runner drive assembly 15 includes a servo cylinder 151. A ratchet mechanism 152 is pushed by the servo cylinder, and the runner 14 is driven to rotate through the ratchet mechanism 152. Of course, other drives can also be used to realize the rotation of the runner 14, such as the way of using a stepping motor plus a gear set.

[0021] In this embodiment, a first CCD camera 18 is arranged at the pipe taking port 16. The first CCD camera 18 takes pictures of the grooves 17 through the pipe taking port 16 for image acquisition, and judges whether the pipe bodies in the grooves 17 are empty and whether the directions are correct. The way to judge the correct direction is through the annular groove 102 of the pipe body. If the first CCD camera 18 acquires the image of the annular groove 102, the groove 17 is not empty and the pipe body is placed correctly.

[0022] In an embodiment of the present utility model, please refer to Figure 2 , the feeding assembly 2 includes a feeding gripper 21, a turntable 22, a sliding table 23, a sliding table seat 24, a curve guide rail 25 and a driving oil cylinder 26. The feeding gripper 21 is arranged on the turntable 22. The turntable 22 is arranged on the sliding table 23. The turntable 22 can rotate on the sliding table 23. The sliding table 23 is slidably arranged on the sliding table seat 24. The curve guide rail 25 is arranged on one side of the sliding table seat 24. The driving oil cylinder 26 is connected with the sliding table 23 through a first connecting arm 27. The turntable 22 is slidably connected with the curve guide rail 25 through a second connecting arm 28.

[0023] In this embodiment, the loading gripper 21 is a jaw cylinder, and its jaws extend outwards from the turntable 22. The second connecting arm 28 is in a shape of "7", the upper end of the second connecting arm 28 is connected to the turntable 22, and there is a certain angle between the upper end of the second connecting arm 28 and the loading gripper 21. The lower end of the second connecting arm 28 is arranged in the track of the curve guide rail 25 through a rotating shaft, and the first connecting arm is fixedly connected to the sliding table 23.

[0024] After the loading gripper 21 grabs the pipe body, the shaft of the driving oil cylinder 26 extends out, driving the sliding table 23 to slide, and the sliding table 23 drives the turntable 22 to move. Since the turntable 22 is slidably connected to the curve guide rail 25 through the second connecting arm 28, the turntable 22 will rotate automatically while moving, driving the loading gripper 21 to move from the first position A to the second position B.

[0025] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
