[0004] The low-friction vacuum suction rod strong magnet rebound device provided in this application adopts the following technical solution:

[0006] The vacuum suction rod is sleeved on the external threaded outer sleeve, and the vacuum suction rod and the external threaded outer sleeve are threadedly matched; an active cavity is formed between the vacuum suction rod located in the external threaded outer sleeve and the low-friction active vacuum suction tube located in the external threaded outer sleeve; the rebound mechanism is installed in the active cavity, and is used to reduce the friction and noise between the vacuum suction rod and the low-friction active vacuum suction tube.

[0007] By adopting the above technical solution, when clamping the workpiece, the robot arm clamps the outer threaded jacket around, and the robot arm moves downward to drive the low-friction movable vacuum straw to move upward along the movable cavity in the external threaded jacket. The rebound mechanism arranged in the movable cavity enables the low-friction movable vacuum straw to reduce the noise of reciprocating motion when moving. When the low-friction movable vacuum straw resets and moves downward, it helps to move along the inner wall of the movable cavity to reduce friction.

[0008] Optionally, the rebound mechanism includes a strong magnet ring A and a strong magnet ring B, the strong magnet ring A / strong magnet ring B are movably mounted on a vacuum suction rod located in the movable cavity, the strong magnet ring A and the vacuum suction pipe are against each other, and the strong magnet ring B and the low-friction movable vacuum suction pipe are against each other.

[0009] By adopting the above technical solution, strong magnet ring A and strong magnet ring B are placed at both ends of the movable cavity. The interaction force makes the low-friction movable vacuum straw slide more flexibly in the external threaded jacket, reducing the noise between them.

[0010] Optionally, the low-friction movable vacuum suction tube is also provided with a nylon positioning sleeve, and the nylon positioning sleeve abuts against the inner wall of the external threaded outer sleeve.

[0011] By adopting the above technical solution, the nylon positioning sleeve arranged between the low-friction movable vacuum pipe and the external threaded jacket facilitates the low-friction movable vacuum pipe to move along its own axial direction and maintain a good guiding effect.

[0012] Optionally, an internal thread is formed at one end of the low-friction movable vacuum straw away from the movable cavity.

[0013] By adopting the above technical solution, the low-friction movable vacuum pipe and the external equipment are connected by threads, which is convenient for disassembly and installation and simpler to operate.

[0014] Optionally, a sealing rubber ring is sleeved on the vacuum suction rod, and the sealing rubber ring is in contact with the inner wall of the low-friction movable vacuum suction tube.

[0015] By adopting the above technical solution, the vacuum suction rod can be easily moved back and forth along the axial direction on the low-friction movable vacuum suction pipe, thereby reducing friction and noise.

[0016] Optionally, an end of the vacuum suction rod away from the active cavity is provided with an internal thread.

[0017] By adopting the above technical solution, the vacuum suction rod is connected to the vacuum joint on the external equipment by means of threads, which facilitates the installation, maintenance, use and replacement of the vacuum suction rod.

[0018] Optionally, one end of the low-friction movable vacuum pipe away from the movable chamber is also threadedly connected to a suction cup joint, and one end of the suction cup joint away from the low-friction movable vacuum pipe is also detachably connected to a suction cup.

[0019] By adopting the above technical solution, the suction cup adsorbs the workpiece through vacuum air pressure suction, and the low-friction movable vacuum suction tube moves in the movable cavity to effectively reduce friction during use and reduce noise.

[0020] Optionally, the strong magnet ring A located in the active cavity and the strong magnet ring B located in the active cavity have the same magnetic properties on opposite surfaces.

[0021] By adopting the above technical solution, the relative surfaces have the same magnetic properties, and the strong magnet ring A and the strong magnet ring B generate repulsive force in the movable cavity, which helps the low-friction movable vacuum straw and the external threaded jacket to slide in the movable cavity, reduce friction, and facilitate the resetting and ejection of the low-friction movable vacuum straw.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When the low-friction active vacuum pipette and the external threaded jacket slide relative to each other, the rebound mechanism arranged in the active cavity effectively reduces the friction and noise between components;

[0024] 2. When the low-friction active vacuum straw is reset, the same-sex strong magnetic poles of the rebound mechanism repel each other, which speeds up the reset speed and improves the working efficiency;

[0025] 3. Use the strong magnetic repulsion to reduce friction during back and forth movement and increase the service life of components. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] Embodiment 1

[0034] See also Figure 3As shown, an embodiment of the present application discloses a low-friction vacuum suction rod strong magnet rebound device, comprising: a vacuum suction rod 1, a low-friction movable vacuum suction pipe 2, an external threaded jacket 3 and a rebound mechanism 4; the low-friction movable vacuum suction pipe 2 is movably sleeved on the vacuum suction rod 1, and the external threaded jacket 3 is movably sleeved on the low-friction movable vacuum suction pipe 2; the vacuum suction rod 1 is sleeved on the external threaded jacket 3, and the vacuum suction rod 1 and the external threaded jacket 3 are threadedly matched; an active cavity 5 is formed between the vacuum suction rod 1 located in the external threaded jacket 3 and the low-friction movable vacuum suction pipe 2 located in the external threaded jacket 3; the rebound mechanism 4 is installed in the active cavity 5, for reducing the friction and noise between the vacuum suction rod 1 and the low-friction movable vacuum suction pipe 2.

[0035] In this embodiment, the rebound mechanism 4 in the active chamber 5 adopts a spring 10, and the spring 10 is located between the vacuum suction rod 1 and the low-friction active vacuum pipette 2, and the spring 10 is sleeved on the vacuum suction rod 1. The low-friction active vacuum pipette 2 moves smoothly along the axial direction of the vacuum suction rod 1, reducing the noise generated during movement. The low-friction active vacuum pipette 2 moves upward to squeeze the spring 10, which plays an effective buffering protection and reduces the occurrence of collision between the end of the low-friction active vacuum pipette 2 and the end of the vacuum suction rod 1.

[0036] Embodiment 2

[0038] See also Figure 1 and Figure 2As shown, the rebound mechanism 4 includes a strong magnet ring A41 and a strong magnet ring B42. The strong magnet ring A41 / strong magnet ring B42 are movably sleeved on the vacuum suction rod 1 located in the movable chamber 5. The strong magnet ring A41 and the vacuum suction pipe are against each other, and the strong magnet ring B42 and the low-friction movable vacuum suction pipe 2 are against each other. The relative surfaces of the strong magnet ring A41 and the strong magnet ring B42 located in the movable chamber 5 have the same magnetic properties. The relative surfaces of the strong magnet ring A41 and the strong magnet ring B42 have the same magnetic properties, and they repel each other, so that a certain gap is generated between the low-friction vacuum suction pipe and the vacuum suction rod 1, thereby reducing the collision between the end of the low-friction movable vacuum suction pipe 2 and the vacuum suction rod 1 during resetting, thereby accelerating the resetting speed of the low-friction movable vacuum suction pipe 2 and improving work efficiency.

[0039] See also Figure 1 As shown, the low-friction movable vacuum pipe 2 is also provided with a nylon positioning sleeve 6, which abuts against the inner wall of the external threaded jacket 3. The nylon positioning sleeve 6 helps to guide the low-friction movable vacuum pipe 2 when it moves along its own axis, thereby reducing the friction between the low-friction movable vacuum pipe 2 and the external threaded jacket 3.

[0040] See also Figure 1 As shown, the end of the low-friction movable vacuum pipette 2 away from the movable chamber 5 is provided with an internal thread, and the end of the vacuum suction rod 1 away from the movable chamber 5 is provided with an internal thread. The adopted threaded method facilitates the installation and disassembly of the connecting end of the low-friction movable vacuum pipette 2 and the vacuum suction rod 1, is convenient for workers to operate easily, and saves working time.

[0041] See also Figure 1 As shown, a sealing rubber ring 7 is sleeved on the vacuum suction rod 1, and the sealing rubber ring 7 is in contact with the inner wall of the low-friction movable vacuum suction tube 2, thereby reducing the noise caused by the friction between the vacuum suction rod 1 and the low-friction movable vacuum suction tube 2.

[0042] See also Figure 4 As shown, the end of the low-friction movable vacuum suction tube 2 away from the movable chamber 5 is also threadedly connected to a suction cup joint 8, and the end of the suction cup joint 8 away from the low-friction movable vacuum suction tube 2 is also detachably connected to a suction cup 9, which relies on the suction cup 9 to adsorb and contact the workpiece. The suction cup 9 has various styles and models and is detachable for easy replacement and maintenance.

[0043] The implementation principle of a strong magnet rebound device for a low-friction vacuum suction rod 1 in an embodiment of the present application is as follows: the vacuum organ joint on the equipment is connected to the threaded part on the vacuum suction rod 1, the suction cup joint 8 and the threaded part of the low-friction movable vacuum suction tube 2 are connected and tightened, and the movable part of the manipulator clamps the external threaded sleeve 3. The robot moves to the end face of the workpiece to be sucked, and the robot arm presses down to contact the workpiece to make the suction cup 9 and the workpiece to be sucked firmly. Due to the downward pressure of the robot arm, the low-friction movable vacuum pipette 2 moves upward in the movable cavity 5 of the external threaded sleeve 3. At this time, the strong magnet ring A41 and the strong magnet ring B42 are opposite to each other and have the same magnetic properties. The low-friction movable vacuum pipette 2 applies force downward to firmly suck the suction cup 9 and the workpiece to be sucked, and then moves to the position where the workpiece is placed. The vacuum hose transmits the vacuum air pressure to the suction cup 9 and releases it. At the same time, the low-friction movable vacuum pipette 2 is repelled by the mutual repulsion of the like magnetic poles of the strong magnet A and the strong magnet B, so that the low-friction movable vacuum pipette 2 is pushed downward along the external threaded sleeve 3. During the pushing process, the strong magnetic repulsion force replaces the spring 10, which helps to speed up the resetting of the low-friction movable vacuum pipette 2. At the same time, the friction and the noise generated during the resetting process are reduced, effectively extending the service life.
