[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figure 1 and Figure 2 As shown, the suction execution component of this embodiment of the invention includes a fixing component 1 and a suction component 2.

[0035] The fixing component 1 includes a first connector 11, which has a first channel suitable for vacuuming. The magnetic strength of the first connector 11 is adjustable. Figure 2 As shown, the first connector 11 can be cylindrical and generally extends in the vertical direction. The first channel is located inside the first connector 11. The first channel can be an L-shaped channel with two ports. One port can be located on the outer peripheral wall of the first connector 11, and the other port can be located on the bottom end face of the first connector 11.

[0036] An electromagnet can be installed inside the first connector 11, and the electromagnet is electrically connected to a power source via a wire. During use, the magnetic strength of the first connector 11 can be adjusted by regulating the strength of the electromagnet's magnetism.

[0037] The suction component 2 is magnetic or has magnetic properties so that it can be magnetically connected to the first connector 11. The suction component 2 is provided with a second channel, which is adapted to communicate with the first channel so that the suction component 2 can pick up materials or devices when the first channel is evacuated.

[0038] like Figure 1 As shown, the suction component 2 can be installed below the first connector 11. A part of the suction component 2 is magnetic or has a certain magnetism. The suction component 2 can be connected to the first connector 11 through magnetic attraction, which facilitates the installation and removal of the suction component 2.

[0039] The second channel is located inside the suction component 2. When the suction component 2 is installed on the first connector 11, the second channel can be connected to the first channel inside the first connector 11. Thus, the suction component 2 can be vacuumed through the first channel and the second channel. The negative pressure formed by the suction component 2 can be used to suction materials or devices, thereby facilitating the movement of materials or devices.

[0040] It should be noted that, since the magnetic strength of the first connector 11 is adjustable, the magnetic attraction between the first connector 11 and the suction assembly 2 can be adjusted by changing the magnetic strength of the first connector 11, thus facilitating the disassembly and fixing of the suction assembly 2. Furthermore, because the first connector 11 always possesses magnetism, the suction assembly 2 and the first connector 11 can still be magnetically connected and fixed in the event of equipment malfunction or sudden power failure, ensuring the stability of equipment operation.

[0041] In this embodiment of the invention, the suction component 2 and the fixing component 1 are connected and fixed by magnetic attraction, which facilitates the quick replacement of the suction nozzle 22, reduces the time for troubleshooting, avoids production delays, and helps to improve production efficiency and automation.

[0042] In some embodiments, the suction assembly 2 includes a second connector 21 and a suction nozzle 22, a second channel is formed in the second connector 21, the suction nozzle 22 is connected to the second connector 21 and communicates with the second channel, and the second connector 21 is adapted to be magnetically connected to the first connector 11.

[0043] Specifically, such as Figure 2 As shown, the second connector 21 can be cylindrical and generally extends in the vertical direction, and the suction nozzle 22 can be fixed to the bottom of the second connector 21. The second channel is provided inside the second connector 21 and extends along the axial direction (vertical direction) of the second connector 21. The second connector 21 can be made of a magnetically conductive material. The top of the second connector 21 can be magnetically connected to the bottom of the first connector 11, thereby realizing the connection and fixation of the suction component 2 and the fixing component 1.

[0044] like Figure 2 As shown, the suction nozzle 22 can be a suction cup, and the inner cavity of the suction nozzle 22 can be connected to the second channel. When in use, a vacuum can be drawn at the suction nozzle 22 through the first channel and the second channel. The negative pressure formed at the suction nozzle 22 can suck up materials or devices.

[0045] In some embodiments, one of the first connector 11 and the second connector 21 is provided with a tapered portion 111 and the other is provided with a tapered groove 211. The tapered portion 111 is adapted to fit into the tapered groove 211 so that the first connector 11 and the second connector 21 can be aligned and connected.

[0046] Specifically, such as Figure 2 As shown, the tapered portion 111 can be located at the bottom end of the first connector 11. The tapered portion 111 is a frustum section, and its radial dimension gradually decreases from top to bottom. The tapered groove 211 can be located at the top of the second connector 21. The shape of the tapered groove 211 matches the shape of the tapered portion 111, and its radial dimension gradually decreases from top to bottom.

[0047] When the first connector 11 and the second connector 21 are magnetically connected, the tapered part 111 can be inserted into the tapered groove 211. The guiding effect of the outer peripheral surface of the tapered part 111 and the groove wall of the tapered groove 211 can facilitate the alignment and connection of the first connector 11 and the second connector 21, thereby improving the assembly accuracy of the first connector 11 and the second connector 21.

[0048] In some embodiments, the suction assembly 2 includes a magnet 23 disposed within the second connector 21 to make the second connector 21 magnetic. Figure 2 As shown, magnet 23 can be a magnet and can be fixed inside the second connector 21. Magnet 23 can magnetize the second connector 21, thereby giving the second connector 21 a certain magnetism and ensuring the firmness of the connection between the first connector 11 and the second connector 21.

[0049] Optionally, the magnet 23 can be ring-shaped and can be installed in the second channel. The inner hole of the magnet 23 can allow airflow to pass through, thereby facilitating vacuuming.

[0050] In some embodiments, there are multiple magnets 23, each magnet 23 including multiple N-pole magnets and multiple S-pole magnets. The multiple N-pole magnets and multiple S-pole magnets are arranged alternately along the circumference of the suction assembly 2. The first connector 11 is provided with multiple N-pole magnets and multiple S-pole magnets, which are arranged alternately along the circumference of the first connector 11. The N-pole magnets and S-pole magnets are magnetically connected, and the S-pole magnets and N-pole magnets are magnetically connected.

[0051] Specifically, multiple N-pole magnets and multiple S-pole magnets can be fixed on the second connector 21. The multiple N-pole magnets and multiple S-pole magnets are arranged at intervals and distributed in a circle along the circumferential direction of the second connector 21, and the multiple N-pole magnets and multiple S-pole magnets are arranged alternately along the circumferential direction of the second connector 21.

[0052] Similarly, multiple N magnetic poles and multiple S magnetic poles are provided on the first connector 11. The multiple N magnetic poles and multiple S magnetic poles are arranged at intervals and distributed in a circle along the circumferential direction of the first connector 11, and the multiple N magnetic poles and multiple S magnetic poles are arranged alternately along the circumferential direction of the first connector 11.

[0053] In use, multiple N-pole magnets are magnetically connected to multiple S-pole magnets in a one-to-one correspondence, and multiple S-pole magnets are magnetically connected to multiple N-pole magnets in a one-to-one correspondence. Thus, each N-pole magnet is held in a position attracted to its corresponding S-pole by the repulsive force between adjacent N-pole magnets, thereby preventing the first connector 11 and the second connector 21 from easily rotating relative to each other and improving assembly stability.

[0054] In some embodiments, the suction assembly 2 includes a sealing ring 24 adapted to be clamped between a first connector 11 and a second connector 21 to sealably connect the first connector 11 and the second connector 21. Figure 2 As shown, the sealing ring 24 can be an O-ring rubber ring. The sealing ring 24 can be installed in the second channel. When the conical part 111 of the first connector 11 is inserted into the conical groove 211 of the second connector 21, the sealing ring 24 can be clamped and fixed between the first connector 11 and the second connector 21, thereby achieving a sealing effect, thus ensuring the vacuuming effect and avoiding the situation where air leakage causes poor suction force of the nozzle 22.

[0055] In some embodiments, the fixing component 1 includes a guide sleeve 12 and a guide rod 13, the first connector 11 is connected to the guide rod 13, the guide sleeve 12 is adapted to be fixed in a set position, and the guide rod 13 guides and slides within the guide sleeve 12 so that the first connector 11 is telescopically adjustable.

[0056] like Figure 2 As shown, the guide sleeve 12 can be a cylindrical tube, and the guide rod 13 can be a cylindrical rod. Both the guide sleeve 12 and the guide rod 13 extend generally in the vertical direction, with the guide rod 13 sliding and engaging within the guide sleeve 12. In use, the guide sleeve 12 can be connected and fixed to components such as a robotic arm (set position). The first connector 11 can be directly connected to the bottom end of the guide rod 13. The vertical extension and retraction adjustment of the first connector 11 can be achieved by the upward and downward sliding of the guide rod 13, thereby facilitating the picking up and movement of materials or devices.

[0057] Optionally, such as Figure 2 As shown, a flange 121 may be provided on the outer periphery of the guide sleeve 12. The flange 121 is a flange plate. The flange 121 is arranged around the circumference of the guide sleeve 12. Multiple fixing holes may be provided on the flange 121. The multiple fixing holes are arranged at intervals along the circumference of the flange 121. The fixing holes can be used for fasteners to pass through, thereby facilitating the installation and fixing of the guide sleeve 12.

[0058] In some embodiments, the fixing component 1 includes an elastic element 14, which is sleeved on the outer periphery of the guide rod 13. One end of the elastic element 14 is connected to or abuts against the guide sleeve 12, and the other end of the elastic element 14 is connected to or abuts against the first connector 11. The elastic element 14 is adapted to elastically buffer the first connector 11. Figure 2 As shown, the elastic element 14 can be a spring. The elastic element 14 is sleeved on the outer periphery of the guide rod 13 and connected to the bottom end of the guide sleeve 12. When the first joint 11 moves upward, the first joint 11 can press against the elastic element 14, thereby buffering the first joint 11 and avoiding rigid contact between the first joint 11 and the guide sleeve 12, which helps to improve the stability of operation.

[0059] It is understood that in some other embodiments, the top end of the elastic element 14 can be connected to the guide sleeve 12, and the bottom end of the elastic element 14 can be connected to the first connector 11. During the up-and-down movement of the first connector 11, the elastic element 14 will be compressed or stretched, which can play a buffering role.

[0060] In some embodiments, the fixing component 1 includes an anti-rotation member 15, a guide rod 13 passes through a guide sleeve 12 and is connected to the anti-rotation member 15, one of the anti-rotation member 15 and the guide sleeve 12 is provided with an anti-rotation portion 151 and the other is provided with an anti-rotation groove, the anti-rotation groove extends along the sliding direction of the guide rod 13, the anti-rotation portion 151 is fitted in the anti-rotation groove and can slide along the extension direction of the anti-rotation groove, the anti-rotation portion 151 is adapted to stop against the groove wall of the anti-rotation groove to limit the relative rotation of the guide rod 13 and the guide sleeve 12.

[0061] Specifically, such as Figure 2 As shown, the anti-rotation member 15 can be generally L-shaped. The top end of the guide rod 13 can pass through the top of the guide sleeve 12 and be connected and fixed to the anti-rotation member 15. The anti-rotation part 151 can be provided at the bottom end of the anti-rotation member 15 and integrally formed with the anti-rotation member 15. The anti-rotation groove can be provided on the outer peripheral wall of the guide sleeve 12 and extend along the vertical direction. The anti-rotation part 151 guides and slides in the anti-rotation groove.

[0062] In use, the anti-rotation member 15 can move up and down synchronously with the guide rod 13. During the movement, the anti-rotation part 151 can slide up and down along the anti-rotation groove. Due to the blocking and limiting effect of the anti-rotation member 15 and the groove wall of the anti-rotation groove, the anti-rotation member 15 and the guide sleeve 12 cannot rotate relative to each other, thereby avoiding the relative rotation of the guide rod 13 and the guide sleeve 12 and ensuring the stability of the suction assembly 2 in use.

[0063] In some embodiments, the fixing component 1 includes a bearing 16, which is fitted inside the guide sleeve 12 and sleeved on the outer periphery of the guide rod 13. The bearing 16 is adapted to reduce the friction of the guide rod 13 when it slides. Figure 2 As shown, the bearing 16 can be a linear bearing 16, which can be assembled inside the inner hole of the guide sleeve 12. The assembly method can be an interference fit, and the guide rod 13 can be fitted inside the bearing 16. Therefore, during the sliding process of the guide rod 13, the bearing 16 can reduce the friction between the guide rod 13 and the guide sleeve 12, thereby improving the smoothness of sliding.

[0064] In some embodiments, the fixing component 1 includes a limiting member 17, and a limiting groove is provided in the guide sleeve 12. The limiting member 17 is fitted into the limiting groove and is adapted to stop the bearing 16. Figure 2As shown, the limiting member 17 can be a snap ring, and the limiting groove can be an annular groove and provided in the guide sleeve 12. The limiting groove can be embedded in the limiting groove. The inner hole of the guide sleeve 12 can be provided with an annular protrusion. The bottom end of the bearing 16 can be stopped by the annular protrusion, and the top end of the bearing 16 can be stopped by the limiting member 17, thereby preventing the bearing 16 from moving up and down and facilitating the assembly and replacement of the bearing 16.

[0065] In some embodiments, the suction execution component includes an endotracheal connector 3, which is connected to a first connector 11 and communicates with a first channel. For example... Figure 1 and Figure 2 As shown, the duct connector 3 can be connected to the side wall of the first connector 11. The duct connector 3 can be connected to a vacuum pump, thus facilitating vacuuming.

[0066] The following describes the method for replacing the suction nozzle according to an embodiment of the present invention.

[0067] The method for replacing the suction nozzle according to an embodiment of the present invention includes the following steps:

[0068] S1: Adjust the magnetic strength of the first connector 11 to reduce the magnetic attraction between the first connector 11 and the suction assembly 2. Specifically, the host computer can monitor or predict abnormalities or wear of the suction nozzle 22. When the suction nozzle 22 needs to be replaced, the magnetic strength of the first connector 11 can be reduced by adjusting the current flowing into the first connector 11. As a result, the magnetic attraction between the first connector 11 and the suction assembly 2 will be weakened, making it easier to remove the suction assembly 2 from the first connector 11.

[0069] S2: Remove and replace the suction component 2 manually or by machine. During use, the suction component 2 can be replaced manually or by machine.

[0070] S3: Adjust the magnetic strength of the first connector 11 to enhance the magnetic attraction between the first connector 11 and the suction component 2. Specifically, after the suction component 2 is replaced, the magnetic strength of the first connector 11 can be enhanced by adjusting the current flowing into the first connector 11. As a result, the magnetic attraction between the first connector 11 and the suction component 2 will be enhanced, thereby improving the stability of the suction component 2 and preventing the suction component 2 from easily becoming loose.

[0071] In some embodiments, step S4 may be included: visually identifying and positioning the first connector 11 and the suction component 2, determining the alignment of the first connector 11 and the suction component 2, and if the first connector 11 and the suction component 2 are significantly offset, then re-magnetically aligning them.

[0072] Specifically, the first connector 11 and the suction component 2 can be visually identified and positioned using a visual recognition and positioning system such as a camera monitoring system. The images captured by the camera can be transmitted to the corresponding processor for analysis and processing, thereby determining the alignment of the first connector 11 and the suction component 2. When the offset between the first connector 11 and the suction component 2 is large, the suction component 2 can be reinstalled or its position corrected, thus ensuring the structural stability for subsequent use.

[0073] In some embodiments, the nozzle replacement method further includes step S5: detecting the magnetic attraction force of the first connector 11 and the suction component 2, comparing the magnetic attraction force with the load of the object to be attracted, and if the load is greater than the magnetic attraction force, adjusting the current of the first connector 11 to enhance the magnetic attraction force.

[0074] Specifically, the magnetic attraction between the first connector 11 and the suction component 2 can be detected by measuring the current flowing through the first connector 11. In a production line, the specifications of the objects to be adsorbed are generally consistent across the same production line. The load of the object can be obtained by measuring the weight of a single object. By comparing the magnetic attraction with the load, if the weight of the object is greater than the magnetic attraction between the first connector 11 and the suction component 2, the magnetic attraction can be increased by increasing the current flowing through the first connector 11, thereby ensuring the structural strength of the adsorption.

[0075] In some embodiments, the method for replacing the suction nozzle includes step S7: monitoring the adsorption pressure of the suction component 2; if the adsorption pressure is abnormal, re-adsorbing or increasing the adsorption pressure to re-adsorb.

[0076] Specifically, during the adsorption process, the adsorption pressure inside the adsorption component 2 can be monitored in real time using devices such as pressure gauges. If a sudden change in adsorption pressure occurs, it can be determined that the adsorbent has failed to adsorb well with the adsorption component 2, and then it can be re-adsorbed. Alternatively, the adsorption pressure can be increased first, and then adsorption can be performed again, thereby avoiding the situation of moving without load during operation and ensuring operational efficiency.
