Technical Field

[0001] This application relates to the field of camera module assembly technology, and in particular to a magnetic quick-release nozzle and a method for assembling and disassembling the nozzle head. Background Technology

[0002] During the assembly of the camera module, the suction nozzles of the related equipment are mostly fixed to the motor output shaft by threads or snap-fit ​​structures. When changing different models of suction nozzles, tools are required for disassembly and assembly, which is cumbersome and time-consuming.

[0003] This disassembly and assembly method not only leads to low nozzle replacement efficiency and prolonged equipment downtime, affecting overall production efficiency, but also makes it difficult to guarantee the positioning accuracy of the nozzle relative to the motor shaft after replacement. Positioning deviations are prone to occur, causing poor air circuit connection between the nozzle head and the air extraction equipment. Therefore, each replacement requires tedious re-alignment and coordinate calibration, further increasing downtime. At the same time, it places high demands on the technical level of operators, severely restricting the production line's ability to quickly change over. Summary of the Invention

[0028] In the fully automated film application and tray arrangement process of camera modules, multiple gripping, handling and positioning operations are required for related components. The magnetic quick-release nozzle provided in this embodiment is applied to the fully automated film application and tray arrangement production line of camera modules, specifically involving an adsorption device in the production line for gripping, handling and positioning of components.

[0029] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0030] Firstly, such as Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a magnetic quick-release suction nozzle, including: a suction nozzle seat 10, in which a first channel 101 is provided for communicating with an air extraction device; a suction nozzle head 20, which has a second channel 201; and a magnetic suction assembly 30, which includes a first magnetic suction part 301 and a second magnetic suction part 302. The first magnetic suction part 301 is disposed on one of the suction nozzle seat 10 and the suction nozzle head 20, and the second magnetic suction part 302 is disposed on the other of the suction nozzle seat 10 and the suction nozzle head 20. The first magnetic suction part 301 and the second magnetic suction part 302 can be magnetically connected so that the suction nozzle seat 10 and the suction nozzle head 20 are magnetically connected, and the second channel 201 is connected to the first channel 101.

[0031] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the magnetic quick-release nozzle includes a nozzle base 10, which connects the suction device and the nozzle head 20. The nozzle base 10 has a first channel 101 connected to the suction device. It should be noted that the nozzle base 10 and the suction device are always connected, and the first channel 101 remains connected to the suction device. Subsequent nozzle replacement operations only require disassembling and assembling the nozzle head 20 and the nozzle base 10; it is not necessary to disassemble the connection structure between the nozzle base 10 and the suction device.

[0032] One of the nozzle holder 10 and the nozzle head 20 is provided with a first magnetic attraction part 301, and the other is provided with a second magnetic attraction part 302. When the nozzle holder 10 and the nozzle head 20 are close together, the first magnetic attraction part 301 and the second magnetic attraction part 302 are magnetically connected, thus magnetically connecting the nozzle holder 10 and the nozzle head 20. After the nozzle holder 10 and the nozzle head 20 are connected, the first channel 101 on the nozzle holder 10 and the second channel 201 on the nozzle head 20 are also connected. At this time, the suction device, the first channel 101 and the second channel 201 are all connected, so that when the suction device starts the suction operation, the gas on the surface of the object to be adsorbed can pass through the second channel 201 and the first channel 101 in sequence and finally be extracted by the suction device, thereby forming a negative pressure at the contact position between the object to be adsorbed and the nozzle head 20, realizing the adsorption of the object to be adsorbed.

[0033] Understandably, the above solution utilizes magnetic attraction to achieve a quick connection between the nozzle holder 10 and the nozzle head 20. The disassembly and assembly of the nozzle head 20 can be completed without the need for other auxiliary tools, solving the problems of cumbersome and time-consuming disassembly and assembly of threaded or snap-fit ​​nozzles in related technologies. This shortens nozzle replacement time, reduces equipment downtime, and improves the overall operating efficiency of the production line. Simultaneously, the magnetic connection process enables automatic alignment of the nozzle holder 10 and the nozzle head 20, ensuring that the first channel 101 and the second channel 201 are connected after connection. This avoids the positioning deviations and poor airflow issues that easily occur after replacing the nozzle head 20 using threaded or snap-fit ​​disassembly methods in related technologies. It eliminates the need for tedious realignment after nozzle head 20 replacement, reducing the technical skill requirements for operators and simplifying the operation process. In addition, the nozzle holder 10 and the air extraction device are stably connected through the first channel 101. Subsequent replacements only require the nozzle head 20 and the nozzle holder 10 to be replaced without disassembling the connection structure between the nozzle holder 10 and the air extraction device. This further simplifies the disassembly and assembly process and improves the convenience and efficiency of nozzle replacement.

[0034] It should be noted that the air extraction equipment can be a negative pressure fan or a vacuum pump; no specific type of air extraction equipment is restricted here.

[0035] It should be noted that the first magnetic attraction part 301 and the second magnetic attraction part 302 can both be set as permanent magnets, or one of them can be set as a permanent magnet and the other as a magnetically conductive metal part, as long as the nozzle seat 10 and the nozzle head 20 can be magnetically connected. There are no restrictions on this.

[0036] In some embodiments, such as Figure 1 As shown, the magnetic quick-release nozzle also includes a limiting structure 40, which is disposed between the nozzle seat 10 and the nozzle head 20. The limiting structure 40 is used to restrict the relative movement of the nozzle head 20 and the nozzle seat 10 along the magnetic attraction direction perpendicular to the first magnetic attraction part 301 and the second magnetic attraction part 302 after the first magnetic attraction part 301 and the second magnetic attraction part 302 are magnetically connected.

[0037] Specifically, such as Figure 1 As shown, since the nozzle head 20 and the nozzle seat 10 are only connected by magnetic attraction, after the first magnetic attraction part 301 and the second magnetic attraction part 302 are magnetically engaged, the nozzle head 20 and the nozzle seat 10 only have adsorption constraint force in the magnetic attraction direction. Therefore, the nozzle head 20 and the nozzle seat 10 are prone to relative displacement under the action of external force along the magnetic attraction direction perpendicular to the first magnetic attraction part 301 and the second magnetic attraction part 302, which leads to misalignment of the first channel 101 and the second channel 201, affecting the normal conduction of the overall air path of the magnetic quick-release nozzle. Therefore, the magnetic quick-release nozzle also includes a limiting structure 40, which is disposed between the nozzle seat 10 and the nozzle head 20. After the first magnetic attraction part 301 and the second magnetic attraction part 302 are connected, the limiting structure 40 can restrict the relative movement of the nozzle head 20 and the nozzle seat 10 along the magnetic attraction direction perpendicular to the first magnetic attraction part 301 and the second magnetic attraction part 302.

[0038] Understandably, by adding a limiting structure 40 between the nozzle seat 10 and the nozzle head 20, the relative movement of the nozzle head 20 and the nozzle seat 10 along the direction perpendicular to the magnetic attraction can be restricted after the first magnetic attraction part 301 and the second magnetic attraction part 302 have completed the magnetic attraction connection. This prevents the nozzle head 20 and the nozzle seat 10 from being misaligned due to external forces, ensuring that the first channel 101 and the second channel 201 always remain in an aligned and connected state. This ensures the stability and reliability of the air passage of the magnetic quick-release nozzle, while maintaining the accuracy of the suction position of the nozzle head 20 on the object to be attracted, and avoiding problems such as adsorption failure and positioning deviation caused by structural misalignment.

[0039] In some embodiments, the limiting structure 40 may include a positioning pin and a positioning hole. One of the nozzle seat 10 and the nozzle head 20 is provided with a positioning hole, and the other is provided with a positioning pin. The axial direction of the positioning pin and the axial direction of the positioning hole may be the same as the magnetic attraction direction of the first magnetic attraction part 301 and the second magnetic attraction part 302. The limiting structure 40 is provided with at least two positioning pins and at least two positioning holes. The at least two positioning holes are spaced apart on the corresponding mounting surfaces. The at least two positioning pins are inserted into the corresponding positioning holes as the nozzle seat 10 and the nozzle head 20 are magnetically connected, so that the nozzle head 20 and the nozzle seat 10 form a multi-point limiting constraint in a plane perpendicular to the magnetic attraction direction, thereby restricting the relative movement of the nozzle head 20 and the nozzle seat 10 along the direction perpendicular to the magnetic attraction direction.

[0040] In some embodiments, such as Figure 2 and Figure 3 As shown, the limiting structure 40 includes a limiting step 401 and a limiting groove 402. The limiting step 401 is disposed on one of the nozzle seat 10 and the nozzle head 20, and the limiting groove 402 is disposed on the other of the nozzle seat 10 and the nozzle head 20. The limiting step 401 can extend into the limiting groove 402 along the magnetic attraction direction of the first magnetic attraction part 301 and the second magnetic attraction part 302.

[0041] Specifically, such as Figure 2 and Figure 3 As shown, the limiting structure 40 includes a limiting step 401 and a limiting groove 402. The limiting step 401 protrudes from the nozzle seat 10 or the nozzle head 20 along the magnetic attraction direction of the first magnetic attraction part 301 and the second magnetic attraction part 302. The limiting groove 402 is recessed along the magnetic attraction direction of the first magnetic attraction part 301 and the second magnetic attraction part 302, so that the limiting step 401 can extend into the limiting groove 402 along the magnetic attraction direction of the first magnetic attraction part 301 and the second magnetic attraction part 302. The limiting groove 402 moves the limiting step 401 in a direction perpendicular to the magnetic attraction direction of the first magnetic attraction part 301 and the second magnetic attraction part 302, thereby restricting the relative movement of the nozzle seat 10 and the nozzle head 20 in a direction perpendicular to the magnetic attraction direction of the first magnetic attraction part 301 and the second magnetic attraction part 302.

[0042] Understandably, by setting the limiting structure 40 to a mating form of limiting step 401 and limiting groove 402, and with the limiting step 401 extending into the limiting groove 402 along the magnetic attraction direction, the interlocking structure of the two forms a limiting constraint. This restricts the relative movement of the nozzle seat 10 and the nozzle head 20 along the direction perpendicular to the magnetic attraction after they are magnetically connected, preventing structural misalignment caused by external forces. Simultaneously, the interlocking method of the limiting step 401 along the magnetic attraction direction matches the trajectory of the magnetic connection, without affecting the magnetic docking of the nozzle head 20 and the nozzle seat 10. After interlocking, it also provides auxiliary guidance for the alignment of the first channel 101 and the second channel 201, further ensuring the accuracy and stability of the air passage connection.

[0043] It should be noted that the limiting step 401 can be cylindrical, and the corresponding limiting groove 402 is a matching cylindrical groove. The limiting step 401 can also be cubic, and the corresponding limiting groove 402 is a matching cubic groove. The specific shapes of the two are not restricted here.

[0044] In some embodiments, the limiting structure 40 and the magnetic component 30 are respectively disposed at different positions so that they can function independently, and the magnetic attraction of the magnetic component 30 and the fitting and limiting of the limiting structure 40 do not interfere with each other.

[0045] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the limiting step 401 is provided with a receiving groove 4011, the first magnetic part 301 is provided in the receiving groove 4011, the second magnetic part 302 is provided at the bottom of the limiting groove 402, and the limiting step 401 extends into the limiting groove 402 so that the first magnetic part 301 and the second magnetic part 302 are magnetically connected.

[0046] Specifically, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the limiting step 401 is provided with a receiving groove 4011, and the first magnetic part 301 is disposed in the receiving groove 4011. The opening of the receiving groove 4011 faces the bottom of the limiting groove 402. At the same time, the second magnetic part 302 is disposed at the bottom of the limiting groove 402. When the limiting step 401 extends into the limiting groove 402, the first magnetic part 301 and the second magnetic part 302 are magnetically connected.

[0047] In some embodiments, the first magnetic attraction part 301 can be a permanent magnet. Along the magnetic attraction direction of the first magnetic attraction part 301 and the second magnetic attraction part 302, the side of the first magnetic attraction part 301 away from the bottom of the limiting groove 402 can be fixedly connected to the bottom of the receiving groove 4011. At the same time, the bottom of the limiting groove 402 is directly made of a magnetically conductive metal material so that when the limiting step 401 extends into the limiting groove 402, the first magnetic attraction part 301 and the second magnetic attraction part 302 are magnetically connected to each other to magnetically connect the nozzle seat 10 and the nozzle head 20.

[0048] Understandably, the first magnetic suction part 301 is disposed within the receiving groove 4011 of the limiting step 401, and the second magnetic suction part 302 is correspondingly disposed at the bottom of the limiting groove 402, so that the magnetic suction assembly 30 and the limiting structure 40 are integrated. The process of the limiting step 401 extending into the limiting groove 402 simultaneously completes the magnetic attraction docking of the first magnetic suction part 301 and the second magnetic suction part 302, allowing the magnetic connection and limiting action of the nozzle seat 10 and the nozzle head 20 to be completed in one go, simplifying the docking operation process and improving the assembly efficiency of the nozzle head 20 and the nozzle seat 10. At the same time, this solution makes the area of ​​action of the magnetic attraction force and the limiting constraint coincide. While the magnetic attraction is in contact, the limiting structure 40 completes the fitting, effectively ensuring the coaxiality of the magnetic connection and the effectiveness of the limiting action. It can also reduce the structural space occupied by the connection area between the nozzle seat 10 and the nozzle head 20, making the overall structure more compact.

[0049] In some embodiments, the first channel 101 is located in the region of the nozzle seat 10 away from the limiting step 401, and the second channel 201 is located in the region of the nozzle head 20 away from the limiting groove 402. The limiting step 401 and the limiting groove 402 only serve to limit the nozzle seat 10 and the nozzle head 20, and the air passage is arranged separately from the limiting structure 40. The limiting structure 40 does not participate in air passage conduction, and the arrangement of the channels does not coincide with the limiting structure 40. Both independently perform the functions of limiting and air passage communication.

[0050] In some embodiments, such as Figures 6 to 9 As shown, the first channel 101 passes through one of the limiting step 401 and the limiting groove 402, and the second channel 201 passes through the other of the limiting step 401 and the limiting groove 402. The limiting step 401 extends into the limiting groove 402, and the first channel 101 and the second channel 201 are connected.

[0051] Specifically, such as Figures 6 to 9 As shown, the first channel 101 penetrates one of the limiting step 401 and the limiting groove 402, and the second channel 201 penetrates the other of the limiting step 401 and the limiting groove 402, so that after the limiting step 401 extends into the limiting groove 402, the first channel 101 and the second channel 201 can be connected and connected.

[0052] Understandably, by having the first channel 101 and the second channel 201 pass through the limiting step 401 and the limiting groove 402 respectively, the fitting action of the limiting step 401 into the limiting groove 402 and the docking and connection action of the first channel 101 and the second channel 201 are completed simultaneously. This allows for airflow connection without additional adjustments, improving the assembly and docking efficiency of the nozzle seat 10 and the nozzle head 20. Simultaneously, the integration of the channel with the limiting structure 40 allows the limiting structure 40 to guide and position the docking of the airflow channels while simultaneously limiting them, preventing misalignment and ensuring the stability and sealing of the airflow connection. Furthermore, it eliminates the need for additional space reserved for channel arrangement in the nozzle seat 10 and the nozzle head 20, making the overall nozzle structure more compact.

[0053] In some embodiments, the limiting step 401 is provided with a receiving groove 4011, the first magnetic attraction part 301 is disposed in the receiving groove 4011, and the second magnetic attraction part 302 is disposed at the bottom of the limiting groove 402. Simultaneously, the first channel 101 penetrates one of the limiting step 401 and the limiting groove 402, and the second channel 201 penetrates the other of the limiting step 401 and the limiting groove 402. Furthermore, the first channel 101 also penetrates the first magnetic attraction part 301, and the second channel 201 penetrates... The second magnetic suction part 302 is used to integrate the limiting structure 40, the magnetic suction component 30, the first channel 101, and the second channel 201 into one place. After the limiting step 401 extends into the limiting groove 402, the fitting and limiting of the limiting structure 40, the magnetic connection of the magnetic suction component 30, and the docking and connection of the first channel 101 and the second channel 201 can be completed simultaneously. This further optimizes the arrangement of each structure on the nozzle seat 10 and the nozzle head 20, making the overall structure of the magnetic quick-release nozzle more compact.

[0054] In some embodiments, a sealing member is provided between the outer sidewall of the limiting step 401 and the inner sidewall of the limiting groove 402, and / or, a sealing member is provided between the end face of the limiting step 401 facing the limiting groove 402 and the bottom of the limiting groove 402, so as to seal the connection between the first channel 101 and the second channel 201.

[0055] In some embodiments, such as Figure 2 and Figure 3 As shown, the outer wall of the limiting step 401 and the inner wall of the limiting groove 402 cooperate to form a surface seal, and / or, the end face of the limiting step 401 facing the limiting groove 402 cooperates with the bottom of the limiting groove 402 to form a surface seal.

[0056] Specifically, such as Figure 2 and Figure 3As shown, when the first channel 101 and the second channel 201 respectively penetrate the limiting groove 402 and the limiting step 401, the outer wall of the limiting step 401 and the inner wall of the limiting groove 402 cooperate to form a surface seal, or the end face of the limiting step 401 facing the limiting groove 402 cooperates with the bottom of the limiting groove 402 to form a surface seal. Preferably, the outer wall of the limiting step 401 and the inner wall of the limiting groove 402 cooperate to form a surface seal, and at the same time, the end face of the limiting step 401 facing the limiting groove 402 and the bottom of the limiting groove 402 also cooperate to form a surface seal, so as to further increase the reliability of the seal and prevent gas from leaking from the fitting gap between the limiting step 401 and the limiting groove 402.

[0057] Understandably, by forming a surface seal by fitting the outer wall of the limiting step 401 with the inner wall of the limiting groove 402, and / or by fitting the end face of the limiting step 401 facing the limiting groove 402 with the bottom of the limiting groove 402, the air passage is sealed by utilizing the mating surface of the limiting structure 40. This allows the limiting structure 40 to have both limiting and air passage sealing functions, eliminating the need for an additional sealing element 60 to achieve a seal at the connection between the first channel 101 and the second channel 201. This prevents gas leakage from the mating gap between the limiting step 401 and the limiting groove 402, ensuring that the suction head 20 can form a stable negative pressure vacuum when the suction equipment is pumping air, and preventing problems such as insufficient adsorption force and adsorption failure caused by poor sealing.

[0058] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the suction head 20 includes at least one suction rod 202 and a suction head body 203, with the suction rod 202 being eccentrically designed relative to the geometric center of the suction head body 203; the magnetic quick-release suction nozzle also includes a foolproof component 50, which is disposed between the suction nozzle seat 10 and the suction head body 203. The foolproof component 50 is used to guide the suction nozzle seat 10 and the suction head 20 to a first preset position for magnetic connection, so that the suction rod 202 is positioned at a second preset position.

[0059] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the suction head 20 consists of a suction head body 203 and at least one suction rod 202. The suction rod 202 is eccentrically positioned away from the geometric center of the suction head body 203. The magnetic quick-release suction head is also equipped with a foolproof component 50, which is correspondingly positioned between the suction head seat 10 and the suction head body 203. The foolproof component 50 can form a guiding constraint during the magnetic connection process of the suction head 20 approaching the suction head seat 10, allowing the suction head 20 to complete the magnetic engagement with the suction head seat 10 only at a first preset position. If the relative position of the suction head 20 and the suction head seat 10 deviates from the first preset position, the foolproof component 50 will form an interference block, preventing the magnetic connection between the two. This ensures that the suction head seat 10 and the suction head 20 are always magnetically connected at the first preset position, thereby keeping the suction rod 202 on the suction head body 203 synchronously in a preset second position.

[0060] Understandably, by designing the suction rod 202 off-center relative to the geometric center of the suction head body 203, the suction requirements of the workpiece can be accommodated. Simultaneously, the foolproof component 50, placed between the suction nozzle base 10 and the suction head body 203, guides the suction nozzle base 10 and the suction head 20 to complete the magnetic connection at a first preset position. This ensures that the off-center suction rod 202 is positioned at the second preset position required for the operation, preventing the suction rod 202 from shifting its suction position and guaranteeing the accuracy of the suction position, preventing misalignment, workpiece positioning deviation, or even suction failure. Furthermore, the guiding function of the foolproof component 50 simplifies the docking operation between the suction head 20 and the suction nozzle base 10, eliminating the need for repeated manual adjustments and improving the convenience and efficiency of suction nozzle assembly and disassembly.

[0061] In some embodiments, such as Figure 11 As shown, the suction head 20 also includes a suction cup 204. Along the axial direction of the suction rod 202, the suction cup 204 is disposed at one end of the suction rod 202 away from the suction head body 203. The suction cup 204 is used to adhere to the surface of the object to be adsorbed and to adsorb the object.

[0062] Specifically, such as Figure 11 As shown, the suction head 20 is also equipped with a suction cup 204. Along the axial direction of the suction rod 202, the suction cup 204 is connected to the end of the suction rod 202 away from the suction head body 203. The contact surface of the suction cup 204 is adapted to the surface of the object to be adsorbed. When the air pump is started to form a negative pressure in the air passage, the suction cup 204 can be attached to the surface of the object to be adsorbed, so that a sealed negative pressure chamber is formed between the suction cup 204 and the object to be adsorbed, and then the adsorption of the object to be adsorbed is achieved through the negative pressure adsorption force.

[0063] Understandably, by setting a suction cup 204 at the end of the suction rod 202 away from the suction head body 203, the suction cup 204 is in close contact with the surface of the object to be adsorbed, which effectively increases the adsorption contact area between the suction nozzle and the object to be adsorbed, improves the sealing and stability of the negative pressure adsorption, avoids the problem of air leakage caused by direct contact of the suction rod 202, and prevents the object to be adsorbed from becoming loose or falling off.

[0064] It should be noted that the suction cup 204 can be selected as either a wide-mouth suction cup 204 or a narrow-mouth suction cup 204 depending on the size of the suction surface of the object to be suctioned, and there is no restriction on it here.

[0065] In some embodiments, the suction cup 204 is made of an elastic material to avoid damaging the surface of the object to be suctioned. Specifically, the suction cup 204 is made of elastic material. When the suction cup 204 is attached to the surface of the object to be adsorbed along with the suction nozzle rod 202, the elastic material of the suction cup 204 can achieve soft contact with the surface of the object to be adsorbed through its own flexible deformation, rather than a hard rigid collision. During the attachment process, it can buffer the contact force between the suction nozzle and the object to be adsorbed, thereby avoiding damage to the surface of the object to be adsorbed. Moreover, the elastic deformation can make the suction cup 204 and the surface of the object to be adsorbed form a tight seal, without affecting the stability of the negative pressure adsorption.

[0066] Understandably, the suction cup 204 is made of an elastic material to avoid damage to the surface of the object to be adsorbed. This not only buffers the contact impact force during the adsorption operation through soft contact, preventing surface damage such as scratches, indentations, and cracks on the object to be adsorbed, but also achieves a sealed fit with the surface of the object to be adsorbed by utilizing the deformation characteristics of the elastic material, ensuring the sealing performance and adsorption force stability of the negative pressure adsorption, thus protecting the object to be adsorbed without reducing the reliability of the adsorption operation.

[0067] In some embodiments, such as Figure 12 , Figure 13 and Figure 14 As shown, the suction rod 202 includes a connecting portion 2021 and a stepped portion 2022. Along the axial direction of the suction rod 202, the stepped portion 2022 is located on the side of the connecting portion 2021 away from the suction head body 203. The outer contour dimension of the connecting portion 2021 is smaller than the outer contour dimension of the stepped portion 2022. The suction cup 204 includes a mounting through hole 2041. The mounting through hole 2041 includes a first hole segment 2041a and a second hole segment 2041b. The first hole segment 2041a is connected to the connecting portion 2021, and the second hole segment 2041b is connected to the stepped portion 2022. The diameter of the first hole segment 2041a is smaller than the diameter of the second hole segment 2041b.

[0068] Specifically, such as Figure 12 , Figure 13 and Figure 14As shown, the suction rod 202 is provided with a connecting part 2021 and a step part 2022. Along the axial direction of the suction rod 202, the step part 2022 is located on the side of the connecting part 2021 away from the suction head body 203. The outer contour dimension of the connecting part 2021 is smaller than the outer contour dimension of the step part 2022, and the two are connected to form a step structure. The suction cup 204 has a through mounting hole 2041. The mounting hole 2041 is configured with a first hole section 2041a and a second hole section 2041b with different diameters. The diameter of the first hole section 2041a is smaller than that of the second hole section 2041b. During assembly, the suction cup 204 is fitted onto the suction nozzle rod 202 through the mounting hole 2041. The first hole section 2041a is connected to the connecting part 2021, and the second hole section 2041b is connected to the step part 2022. The step part 2022 helps to limit the suction cup 204 from sliding axially along the suction nozzle rod 202, thus achieving a stable assembly of the suction cup 204 on the suction nozzle rod 202.

[0069] Understandably, by setting the suction rod 202 as a stepped structure of connecting part 2021 and step part 2022, and setting the mounting through hole 2041 of suction cup 204 as the first hole section 2041a and the second hole section 2041b respectively, the assembly of suction cup 204 on suction rod 202 is achieved by using the matching of mounting through holes 2041 with different diameters and the stepped structure. The installation and positioning of suction cup 204 can be completed without additional fasteners, preventing suction cup 204 from sliding axially along suction rod 202 and ensuring the structural stability of suction cup 204 after assembly.

[0070] It should be noted that the connecting part 2021 and the step part 2022 can be integrated with the main body of the suction rod 202, or they can be fixedly connected by welding or bonding. No restrictions are imposed here.

[0071] In some embodiments, such as Figure 9 , Figure 10 As shown, the foolproof component 50 includes a protrusion 501 and a groove 502. The protrusion 501 is disposed on one of the nozzle seat 10 and the nozzle head body 203 and is eccentrically disposed relative to the geometric center of the nozzle seat 10 or the nozzle head body 203. The groove 502 is disposed on the other of the nozzle seat 10 and the nozzle head body 203 and is disposed opposite to the protrusion 501. When the nozzle head 20 and the nozzle seat 10 are magnetically connected, the protrusion 501 and the groove 502 engage.

[0072] Specifically, such as Figure 9 , Figure 10As shown, the foolproof component 50 consists of a matching protrusion 501 and a groove 502. The protrusion 501 is disposed on one of the nozzle seat 10 and the nozzle head body 203, and the protrusion 501 is eccentrically arranged away from the geometric center of the nozzle seat 10 or the nozzle head body 203. The groove 502 is disposed on the other of the nozzle seat 10 and the nozzle head body 203, and the opening position of the groove 502 corresponds to the eccentric position of the protrusion 501. When the nozzle head 20 and the nozzle seat 10 are magnetically connected, the protrusion 501 can only engage with the groove 502 when the two are in the first preset position. If the relative position of the two deviates from the first preset position, the protrusion 501 will interfere with the contact surface of the nozzle seat 10 or the nozzle head body 203, and the engagement and subsequent magnetic connection cannot be achieved. Thus, the foolproof constraint is formed by the engagement of the eccentric protrusion 501 and the groove 502.

[0073] Understandably, the foolproof component 50 is designed with an eccentrically arranged protrusion 501 and a matching groove 502. The engaging fit between the protrusion 501 and the groove 502 creates a foolproof constraint, allowing the nozzle head 20 and nozzle seat 10 to magnetically connect only at the first preset position. This structurally avoids the problem of the nozzle head 20 being misaligned, ensuring that the eccentrically designed nozzle rod 202 is in the second preset position required for operation, thus guaranteeing the accuracy of the nozzle rod 202's adsorption position on the object to be adsorbed. Simultaneously, the protrusion 501 and groove 502 have a simple structural design, eliminating the need for complex positioning structures. While achieving foolproof positioning, it does not increase the overall structural complexity. Furthermore, the engaging action of the protrusion 501 and groove 502 is completed simultaneously with the magnetic connection action, without affecting the ease of assembly and disassembly of the nozzle head 20 and nozzle seat 10. The engaging fit further enhances the structural stability after connection, preventing circumferential rotation during operation.

[0074] In some embodiments, such as Figure 5 As shown, a sealing element 60 is provided at the end of the first channel 101 that connects with the air extraction device.

[0075] Specifically, such as Figure 5 As shown, the sealing element 60 is an annular structure that matches the contour of the mating end of the first channel 101. When the first channel 101 is mated and assembled with the connecting end of the air extraction device, the sealing element 60 is squeezed between the mating surfaces of the mating end of the first channel 101 and the connecting end of the air extraction device, forming a reliable sealing fit.

[0076] It should be noted that the seal 60 can be made of elastic sealing materials such as rubber or silicone, and there are no restrictions on it here.

[0077] Understandably, by providing a seal 60 at the end of the first channel 101 that connects to the extraction device, the seal 60 fills the gap between the first channel 101 and the connection end of the extraction device, preventing gas leakage from the connection point and ensuring the stability of the air path during the operation of the extraction device. This, in turn, ensures that the suction force of the nozzle on the object to be adsorbed remains stable, avoiding problems such as loosening or detachment of the adsorbent due to air leakage at the connection point. At the same time, the seal 60 can buffer the hard contact when the first channel 101 connects to the extraction device, reducing wear on the mating surface and extending the service life of the connection part 2021 between the nozzle and the extraction device.

[0078] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the nozzle holder 10 also includes a clamping groove 102 and a fastener 103. The side wall of the clamping groove 102 has a notch 1021, and both sides of the notch 1021 have locking through holes 1022. The fastener 103 passes through the locking through holes 1022. The first channel 101 is opened at the bottom of the clamping groove 102. The gas connection pipe of the air extraction device is inserted into the clamping groove 102 and communicates with the first channel 101. The clamping groove 102 is used to clamp the gas connection pipe of the air extraction device so that the gas connection pipe of the air extraction device is fixedly connected to the nozzle holder 10.

[0079] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the nozzle seat 10 includes a clamping groove 102. The side wall of the clamping groove 102 has an axially extending notch 1021. Correspondingly, coaxial locking through holes 1022 are provided on the groove walls on both sides of the notch 1021. The fastener 103 is movably inserted into the locking through hole 1022. The first channel 101 is opened along the axial direction of the clamping groove 102 at its bottom and communicates with the air passage inside the nozzle seat 10. The gas connection pipe of the suction device is inserted into the groove along the axial direction of the clamping groove 102, so that the end of the gas connection pipe is connected to the first channel 101 at the bottom of the clamping groove 102 to achieve gas path connection. Tightening the fastener 103 that passes through the locking through hole 1022 can tighten the gap of the notch 1021, so that the inner side wall of the clamping groove 102 contracts towards the center and clamps the outer side wall of the gas connection pipe, thereby achieving a fixed connection between the gas connection pipe and the nozzle seat 10, while ensuring a stable gas path connection after the gas connection pipe is connected to the first channel 101.

[0080] Understandably, by using fastener 103 to tighten notch 1021, the clamping groove 102 clamps and fixes the gas connecting pipe, completing the connection between the gas connecting pipe and the nozzle seat 10 without the need for an additional adapter structure. At the same time, the first channel 101 is opened at the bottom of the clamping groove 102, so that the gas connecting pipe can be directly connected to the first channel 101 after insertion. The clamping groove 102 can also further improve the sealing performance at the connection between the gas connecting pipe and the first channel 101, preventing gas leakage. Moreover, the structure is simple in design, and the clamping connection method will not damage the gas connecting pipe, avoiding problems such as pipe damage and gas leakage caused by rigid connection, ensuring the integrity of the gas connecting pipe and the stability of the gas connection. On the other hand, such as Figure 15 and Figure 16 As shown, this application also provides a method for assembling and disassembling a suction head 20, applicable to any of the magnetic quick-release suction heads described above. The method includes the following steps: during assembly, the suction head 20 is brought close to the suction head seat 10, and under the magnetic attraction of the first magnetic attraction part 301 and the second magnetic attraction part 302, the suction head 20 is magnetically connected to the suction head seat 10, and the first channel 101 is connected to the second channel 201 to form an air passage connected to the air extraction device; during disassembly, an external force is applied to the suction head 20 in the opposite direction of the magnetic attraction of the first magnetic attraction part 301 and the second magnetic attraction part 302 to overcome the magnetic attraction between the first magnetic attraction part 301 and the second magnetic attraction part 302, and the suction head 20 is removed.

[0081] Specifically, such as Figure 15 and Figure 16 As shown, the disassembly and assembly method of the suction head 20 is applied to the aforementioned magnetic quick-release suction head. When assembling the suction head 20, the suction head 20 is directly brought closer to the suction head seat 10. Under the magnetic attraction force between the first magnetic part 301 on the suction head seat 10 and the second magnetic part 302 on the suction head 20, the suction head 20 and the suction head seat 10 automatically complete the magnetic connection. At the same time as the two are connected, the first channel 101 of the suction head seat 10 and the second channel 201 of the suction head 20 are connected and thus form a complete air passage from the air extraction equipment to the suction head 20, which meets the requirements of negative pressure adsorption operation. When disassembling the nozzle head 20, an external force opposite to the magnetic attraction direction is applied to the nozzle head 20. When the magnitude of the external force is greater than the magnetic attraction force between the first magnetic attraction part 301 and the second magnetic attraction part 302, the magnetic attraction connection between the two can be released, and the nozzle head 20 can be removed from the nozzle seat 10. At the same time, the connection between the first channel 101 and the second channel 201 is simultaneously released.

[0082] Understandably, using the above-described method for assembling and disassembling the nozzle head 20, the magnetic attraction force during assembly enables automatic alignment and rapid connection between the nozzle head 20 and the nozzle seat 10, simultaneously completing the air circuit connection. This eliminates the need for repeated manual adjustments, significantly improving the assembly efficiency of the nozzle head 20 and ensuring the stability of the connection and the air circuit's sealing after assembly. Disassembly only requires applying a reverse external force to overcome the magnetic attraction force, allowing for quick removal of the nozzle head 20. No additional tools such as wrenches or screwdrivers are needed throughout the process, making operation simple and quick. This effectively reduces the difficulty of assembling and disassembling the nozzle head 20, meeting the operational needs of rapid model changeovers and routine maintenance on production lines. Furthermore, the entire assembly and disassembly process avoids any forced twisting or snapping of easily damaged structures, effectively protecting the structural integrity of the nozzle seat 10, nozzle head 20, and magnetic assembly 30, reducing component wear during assembly and disassembly, and extending the overall service life of the magnetic quick-release nozzle.

[0083] In some embodiments, the suction head 20 includes at least one suction rod 202 and a suction head body 203. The suction rod 202 is eccentrically designed relative to the geometric center of the suction head body 203. The magnetic quick-release suction head also includes a foolproof component 50, which is disposed between the suction head seat 10 and the suction head body 203. The foolproof component 50 is used to guide the suction head seat 10 to a first preset position for magnetic connection with the suction head 20, so that the suction rod 202 is positioned at a second preset position. During assembly, after the suction head 20 is brought close to the suction head seat 10, the foolproof component 50 is used to guide the suction head 20 to the first preset position for magnetic connection with the suction head seat 10.

[0084] The nozzle head 20 consists of a nozzle head body 203 and at least one nozzle rod 202. The nozzle rod 202 is offset from the geometric center of the nozzle head body 203 and is designed to be eccentric. The foolproof component 50 of the magnetic quick-release nozzle is correspondingly disposed between the nozzle seat 10 and the nozzle head body 203. The disassembly and assembly method of the nozzle head 20 is applied to the above-mentioned magnetic quick-release nozzle. During assembly, the nozzle head 20 is first moved closer to the nozzle seat 10. During the approach process, the directional guidance and alignment are achieved by means of the foolproof component 50. The constraint effect guides the suction head 20 and the suction seat 10 to match to the first preset position. Then, under the magnetic attraction of the first magnetic attraction part 301 and the second magnetic attraction part 302, the suction head 20 and the suction seat 10 complete the magnetic connection at the first preset position. At the same time, the eccentrically designed suction rod 202 is simultaneously placed in the second preset position required for operation. The first channel 101 of the suction seat 10 and the second channel 201 of the suction head 20 are correspondingly connected to form a complete air path connected to the air extraction device.

[0085] Understandably, by combining the magnetic connection with the directional guidance of the foolproof component 50, the nozzle head 20 is guided to the first preset position to complete the magnetic connection after approaching the nozzle seat 10. From an operational perspective, this ensures that the eccentrically designed nozzle rod 202 is stably positioned in the second preset position, avoiding the problem of nozzle rod 202's adsorption position shift due to circumferential alignment deviation of the nozzle head 20, and ensuring the accuracy of the adsorption position of the nozzle rod 202 on the workpiece. At the same time, the guiding action of the foolproof component 50 and the magnetic connection action are smoothly connected, requiring no additional manual adjustment of alignment, simplifying the assembly operation steps, improving the assembly efficiency and alignment accuracy of the nozzle head 20, and adapting to the precise adsorption operation requirements of the eccentric nozzle rod 202 in automated production lines. Moreover, this guiding method relies on the structural constraints of the foolproof component 50, without increasing the complexity of disassembly and assembly operations. While ensuring the accuracy of the adsorption position, it also takes into account the convenience of magnetic quick-release nozzle disassembly and assembly operations and the reliability of the operation.

[0086] In some embodiments, during assembly, the limiting groove 402 of the suction head 20 is aligned with the limiting step 401 of the suction head 10, causing the suction head 20 to move closer to the suction head 10. Under the magnetic attraction of the first magnetic attraction part 301 on the suction head 10 and the second magnetic attraction part 302 on the suction head 20, the suction head 20 and the suction head 10 automatically complete the magnetic attraction and bonding connection. At the same time, the limiting step 401 is embedded in the limiting groove 402 to achieve fitting and limiting. The first channel 101 of the suction head 10 and the second channel 201 of the suction head 20 are connected and connected, thereby forming a complete air path extending from the air extraction device to the suction cup 204 of the suction head 20, which meets the requirements of negative pressure adsorption operation. During disassembly, an axial external force opposite to the magnetic attraction direction is applied to the nozzle head 20. This external force is greater than the magnetic attraction force between the first magnetic attraction part 301 and the second magnetic attraction part 302, thereby overcoming the magnetic attraction constraint and allowing the nozzle head 20 to quickly separate from the nozzle seat 10. At the same time, the connection between the first channel 101 and the second channel 201 is simultaneously released, completing the disassembly of the nozzle head 20. The entire disassembly and assembly process does not require any additional tools and can be achieved simply by applying force manually.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
