[0046] Referring to Figure 1 And Figure 2 The rotary suction head structure provided by the embodiment includes a rotary driving mechanism 1, an air inlet seat 2, a rotary rod 3, an adapter seat assembly 4 and a vacuum suction head 5.

[0047] The air inlet seat 2 is located below the rotary driving mechanism 1, and the air inlet seat 2 is internally provided with an air inlet cavity 201. The upper end of the rotary rod 3 is in transmission connection with the driving end of the rotary driving mechanism 1, and the middle part rotates and seals through the air inlet cavity 201. The rotary rod 3 is internally provided with a rod internal air passage 301 which is communicated to the air inlet cavity 201. The adapter seat assembly 4 is installed at the lower part of the rotary rod 3 and is provided with an air outlet cavity 4013 which is communicated to the rod internal air passage 301. The vacuum suction head 5 is installed at the bottom of the adapter seat assembly 4 and is communicated with the air outlet cavity 4013.

[0048] Optionally, the air inlet seat 2 is connected with an air inlet connector 202 which is communicated to the air inlet cavity 201, and the rotary rod 3 is provided with a first air hole 302 which is communicated from the rod internal air passage 301 to the air inlet cavity 201.

[0049] The rotary rod 3 is provided with a second air hole 303 which is communicated from the rod internal air passage 301 to the external space of the air inlet seat 2, and the adapter seat assembly 4 is provided with a third air hole 4014 which is communicated from the air outlet cavity 4013 to the external space of the adapter seat assembly 4. The second air hole 303 and the third air hole 4014 are communicated through a hose.

[0050] Specifically, the air inlet connector 202 is used to be connected to a vacuumizing device.

[0051] When the workpiece needs to be adsorbed, the vacuum device performs vacuumizing operation through the air inlet joint 202, the air pressure of the air inlet cavity 201 is lowered, and the low pressure is sequentially transmitted to the vacuum suction head 5 through the first air hole 302, the rod air channel 301, the second air hole 303, the hose, the third air hole 4014 and the air outlet cavity 4013, so that the vacuum suction head 5 can adsorb the workpiece;

[0052] After the vacuum suction head 5 adsorbs the workpiece, the rotary driving mechanism 1 drives the rotary rod 3 to rotate, so as to drive the vacuum suction disc and the workpiece to rotate, thereby realizing the rotary displacement operation of the workpiece.

[0053] The rotary suction head structure provided by the utility model reduces the length size of the hose needed by utilizing the internal space of the rotary rod 3 to manufacture the rod air channel 301, so that the problem that the length of the hose needed by the existing suction head structure is long and the hose is difficult to fix and easy to be wound on the surrounding equipment can be solved.

[0054] In the embodiment, the adapter assembly 4 includes an L-shaped adapter plate 401 and a pressure sensor 402. The L-shaped adapter plate 401 includes a longitudinal portion slidingly connected to the rotary rod 3 in an up-down direction, and a transverse portion 4012 provided with the air outlet cavity 4013 and the third air hole 4014. The pressure sensor 402 is fixedly arranged at the bottom of the rotary rod 3 and located above the transverse portion 4012.

[0055] When the workpiece needs to be installed downward to the preset position with appropriate pressure, the process is as follows:

[0056] At the beginning, the L-shaped adapter plate 401 naturally slides downward under the action of gravity, and the pressure detected by the pressure sensor 402 is zero;

[0057] The driving mechanism such as the manipulator drives the rotary suction head structure to move downward, so that the vacuum suction head 5 drives the workpiece to move downward, so that the bottom surface of the workpiece is attached to the top surface of the preset position;

[0058] The driving mechanism continues to drive the rotary suction head structure to gradually move downward, and in the process, the L-shaped adapter plate 401 slides upward relative to the rotary rod 3 and finally abuts against the pressure sensor 402. When the pressure value detected by the pressure sensor 402 reaches the preset value, it indicates that the appropriate installation pressure has been reached, and after a certain pressure maintaining time, the workpiece can be released.

[0059] Optionally, the rotary rod 3 and the air inlet seat 2 are rotationally connected through a bearing 6. Further, a sealing ring or a sealing coating is arranged between the rotary rod 3 and the inner ring of the bearing 6 and between the outer ring of the bearing 6 and the air inlet seat 2, so as to ensure the air tightness of the air inlet cavity 201.

[0060] In summary, the rotating suction head structure provided by the embodiment has the following advantages:

[0061] ① Reduce the length of the hose: by utilizing the internal space of the rotating rod 3 to make the rod air channel 301, the required length of the hose is effectively reduced, solving the problem of excessive length of the hose in the existing suction head structure; due to the shortening of the hose length, the hose is easier to fix, and the risk of the hose winding around the surrounding equipment is reduced;

[0062] ② Through the rotating drive mechanism 1, the rotation and position switching operation of the vacuum suction head 5 and the workpiece can be conveniently realized, and the efficiency of the transfer operation is improved;

[0063] ③ Through the L-shaped adapter plate 401 and the pressure sensor 402, the pressure when the workpiece is installed downward to the preset position can be accurately controlled, and the installation quality is ensured;

[0064] ④ The rotating rod 3 and the air inlet seat 2 are connected by bearings 6, and sealing rings or sealing coatings are arranged, so as to ensure the air tightness of the air inlet cavity 201 and improve the adsorption performance of the vacuum suction head 5.
