Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The negative pressure manipulator for transferring articulated cylinders involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides a negative pressure manipulator for transferring articulated cylindrical parts, including a body 1, a head 11 mounted on the body 1, a suction cup 2 mounted on the bottom of the head 11, a cylinder 3 fixedly mounted on the surface of the head 11, a guide shell 4 fixedly mounted on the output end of the cylinder 3, a rotating ring 5 rotatably mounted on the outer surface of the guide shell 4, a motor 7 fixedly mounted on the top of the guide shell 4, and an air extraction component 6 also mounted on the guide shell 4. The cylinder 3 is used to pull the guide shell 4 and the rotating ring 5 to move vertically as a whole, the rotating ring 5 is used to control the extension and retraction of the air extraction component 6, the motor 7 is used to provide power for the rotation of the rotating ring 5, and the air extraction component 6 is used to cooperate with the guide shell 4 to remove dust from the bottom of the suction cup 2. The body 1, the head 11, and the suction cup 2 are existing technologies in the field of negative pressure manipulators, and will not be described in detail here.

[0021] Furthermore, a gear 71 is fixedly connected to the output end of the motor 7, and a rack 51 is fixedly connected to the top inner side of the rotating ring 5. The gear 71 and the rack 51 are meshed together. A trigger block 52 is fixedly connected to the bottom inner side of the rotating ring 5. Multiple trigger blocks 52 are provided and are arranged in an array around the circumference of the rotating ring 5. A guide slope 521 is provided on the trigger block 52. The motor 7 can drive the gear 71 to rotate around its own axis. At the same time, the gear 71 can drive the rotating ring 5 to rotate synchronously around its own axis through the rack 51.

[0022] Furthermore, the suction assembly 6 is provided with multiple corresponding trigger blocks 52. The suction assembly 6 includes a telescopic tube 61, a connecting rod 62, and a sliding rod 64. The telescopic tube 61 is a tubular structure with one end open and the other end closed. One end of the telescopic tube 61 extends into the interior of the guide shell 4. One end of the connecting rod 62 is fixedly connected to the telescopic tube 61, and the other end of the connecting rod 62 is fixedly connected to a guide block 621. The guide block 621 matches the guide slope 521. Multiple connecting holes 611 are opened at the top of the telescopic tube 61. The sliding rod 64 is fixedly installed at the bottom of the guide shell 4, and the top of the connecting rod 62 is fixedly... A moving block 63 is fixedly connected to the sliding rod 64. The moving block 63 is sleeved on the surface of the sliding rod 64. The moving block 63 and the sliding rod 64 form a sliding guide fit along the axis of the sliding rod 64. A compression spring is sleeved on the surface of the sliding rod 64. The elastic force of the compression spring drives the telescopic tube 61 to retract into the guide shell 4. During the rotation of the rotating ring 5 and the trigger block 52, the guide inclined surface 521 can squeeze the guide block 621 and push the connecting rod 62 to move synchronously. The moving block 63 slides synchronously along the sliding rod 64. The connecting rod 62 moves and drives the telescopic tube 61 to extend outward from the inside of the guide shell 4.

[0023] Furthermore, an exhaust nozzle 41 is fixedly connected to the top of the flow guide shell 4. The exhaust nozzle 41 is fixedly connected to the vacuum cleaner via a hose 42. Under the action of the vacuum cleaner, the dust on the suction cup 2 can pass through the connecting hole 611, the telescopic tube 61, the flow guide shell 4, the exhaust nozzle 41, and the hose 42 in sequence and be output outward.

[0024] The working principle of this utility model is as follows: When the suction cup 2 needs to be cleaned, the output end of the cylinder 3 extends downward, causing the guide shell 4 and the rotating ring 5 to move downward as a whole. Then, the motor 7 drives the gear 71 to rotate around its own axis. The rotation of the gear 71 drives the rotating ring 5 to rotate synchronously around its own axis through the rack 51. The trigger block 52 also rotates synchronously with the rotating ring 5. During the rotation of the trigger block 52, the guide inclined surface 521 squeezes the guide block 621 and pushes the connecting rod 62 to move synchronously. The moving block 63 at the top of the connecting rod 62 slides synchronously along the sliding rod 64. The compression spring is stretched and its elasticity increases under the pull of the moving block 63. The connecting rod 62 moves and drives the telescopic tube 61 to extend outward from inside the guide shell 4. The telescopic tube 61 comes to the bottom of the suction cup 2. At this time, under the action of the vacuum cleaner, the dust on the suction cup 2 passes through the connecting hole 611, the telescopic tube 61, the guide shell 4, the exhaust nozzle 41 and the hose 42 in sequence and is output outward.

[0025] After the dust is cleaned, the motor 7 rotates in the opposite direction. Similarly, the rotating ring 5 and the trigger block 52 rotate in the opposite direction. The guide slope 521 gradually loosens its pressure on the guide block 621. The elastic force of the compression spring is released and drives the telescopic tube 61 to retract into the guide shell 4. The output end of the cylinder 3 then shortens upward. The guide shell 4 and the rotating ring 5 return to their initial positions. The suction cup 2 can continue to transfer the joint cylinder.
