Description

Technical Field

[0001] This application relates to the field of rotary suction nozzle mechanism technology, and more specifically, to a rotary suction nozzle mechanism. Background Technology

[0002] In the manufacturing process of mobile phones and other electronic products, adhesive components need to be adsorbed, transferred, and assembled. Traditional adsorption and transfer equipment mostly lacks stable heating functions, and the adhesive layer is prone to insufficient adhesion due to unsuitable temperature, resulting in problems such as detachment and loosening, which affects product quality.

[0003] Meanwhile, these components are mostly irregularly shaped, making it difficult for traditional equipment to achieve precise angle adjustment, resulting in difficult assembly alignment and reduced assembly efficiency. Traditional equipment generally lacks a reliable pressure sensing mechanism, making it impossible to accurately control the adsorption pressure, which can easily cause damage to components or poor adsorption. In addition, some equipment has problems such as poor sealing performance and poor rotation smoothness, making it difficult to meet the high precision and high stability requirements of precision manufacturing for the transfer and pasting process, thus restricting the improvement of production efficiency and product qualification rate.

[0004] Therefore, this application proposes a rotary suction nozzle mechanism to solve the aforementioned problems.

[0005] Application content

[0006] To address the aforementioned problems, this application provides a rotary suction nozzle mechanism.

[0007] The rotary suction nozzle mechanism provided in this application adopts the following technical solution:

[0008] A rotary suction nozzle mechanism, comprising:

[0009] The housing includes an upper housing and a lower housing;

[0010] A servo motor is provided at the top of the upper housing. A first connecting component connected to the output shaft of the servo motor is provided inside the upper housing. A second connecting component is slidably connected below the connecting component. A through pipe is fixedly connected to the bottom of the second connecting component. The through pipe is connected to a through rod and a suction nozzle from top to bottom.

[0011] The cavity inside the lower housing is a sealed structure. A valve communicating with the cavity is provided on the side of the lower housing. A first air hole communicating with the air passage of the cavity is provided on the side of the pipe.

[0012] A rotating cylinder is rotatably disposed inside the lower housing, and a second air hole communicating with the cavity air passage is opened transversely through the rotating cylinder;

[0013] The rotating cylinder extends downward from the lower housing, and the top of the rotating cylinder is fixedly connected to the first connecting component;

[0014] The upper half of the through pipe and the through rod are both located in the rotating drum, and the lower half of the rotating rod is fitted with a T-shaped central positioning sealing sleeve, which is inserted into the bottom of the rotating drum.

[0015] Furthermore, the inner rings of the upper and lower openings of the lower housing are each provided with a first bearing, and the inner rings of the first bearings are sleeved on the outside of the rotating cylinder.

[0016] By employing the aforementioned technical solution, a first bearing is installed on the inner ring of the upper and lower openings of the lower housing and fitted onto the outside of the rotating cylinder. This effectively reduces the coefficient of friction between the rotating cylinder and the lower housing during rotation, decreases wear between components, and significantly extends the overall service life of the mechanism. The bearing ensures smoother rotation of the rotating cylinder, avoids rotation angle deviations caused by uneven friction, guarantees the positional accuracy of adhesive-coated components during transport, lays the foundation for precise alignment in subsequent bonding processes, reduces power consumption, improves the energy efficiency and stability of the mechanism, and ensures the reliable execution of precision transport tasks.

[0017] Furthermore, the inner wall of the lower housing is provided with symmetrical annular grooves, and at least two coarse sealing rings are fitted on the rotating cylinder, with the second air hole located within the distance between the two coarse sealing rings.

[0018] Through the above technical solution, the cooperation between the annular groove on the inner wall of the lower housing and the coarse sealing ring on the rotating drum forms a double-sealing protection structure, which greatly enhances the airtightness of the cavity inside the lower housing, effectively prevents gas leakage from the air passage, ensures the stability of the negative pressure required for adsorption, and prevents adhesive-coated components from falling off during transport due to insufficient adsorption force. Limiting the second air hole to the distance between the two coarse sealing rings further optimizes the sealing effect. Furthermore, the annular groove structure facilitates the installation, disassembly, and replacement of the sealing ring, reducing equipment maintenance costs, while not affecting the normal rotation of the rotating drum, thus achieving a balance between sealing performance and mechanical flexibility.

[0019] Furthermore, at least two Y-shaped sealing rings are fitted on the tube, and the first air hole is located within the distance between the two Y-shaped sealing rings. The tube rod, the nozzle, the first air hole, the second air hole, the coarse sealing ring, the Y-shaped sealing ring, and the nozzle together form a complete air passage.

[0020] Through the above technical solution, the Y-shaped sealing ring fitted on the through pipe and the coarse sealing ring on the lower shell form a multi-seal system, comprehensively improving the overall sealing reliability of the air passage, ensuring a continuous and stable negative pressure for adsorption, providing strong and durable adsorption force for adhesive-coated components, and effectively avoiding workpiece detachment or positional displacement caused by seal failure during transportation. The complete air passage design makes the gas flow path simple and smooth, reducing airflow resistance and improving the adsorption response speed. The Y-shaped sealing ring has excellent sealing performance and wear resistance, extending the service life of sealing components, reducing equipment maintenance frequency, and ensuring the continuous and stable operation of the mechanism.

[0021] Furthermore, the first connecting component is a U-shaped structure comprising a base and a vertical cylinder, wherein the base is larger than the diameter of the rotating cylinder and is detachably connected to the top of the rotating cylinder.

[0022] Through the above technical solution, the first connecting component adopts a U-shaped structure. The integrated design of the base and the vertical cylinder ensures the stability of the connection with the rotating cylinder and provides a stable mounting and sliding carrier for the second connecting component. The design of the base being larger than the diameter of the rotating cylinder enhances the load-bearing capacity and stability of the connection part. The detachable connection method facilitates subsequent inspection and replacement of components, reducing maintenance difficulty and cost. The structural design of the vertical cylinder and the base improves the overall rigidity of the first connecting component, avoids deformation under stress, and ensures that the power of the servo motor can be accurately transmitted to the rotating cylinder and the second connecting component, guaranteeing the accuracy and stability of the rotational motion.

[0023] Furthermore, a sliding groove is provided in the first connecting component. The sliding groove extends downward from the upper middle part of the vertical cylinder and passes through the base. The sliding groove also extends laterally through the vertical cylinder.

[0024] The upper half of the second connecting component is a stepped spline structure, and the lower half is a tubular structure that is fixedly connected to the through pipe and blocks the opening at the top of the tubular structure. The width of the lower half is greater than the width of the groove.

[0025] The stepped spline is slidably disposed in the groove, and the outer surface of the first step spline at the top of the stepped spline is threaded. The outside of the first connecting component is fitted with a nut that is threadedly connected to the first section spline.

[0026] Through the above technical solution, the sliding groove of the first connecting component and the stepped spline structure of the second connecting component precisely match, achieving stable sliding of the second connecting component. Its lower tubular structure is fixedly connected to the through-tube and seals the top opening, further ensuring the air passage's sealing. The threaded connection design of the stepped spline and nut allows for flexible adjustment of the second connecting component's position, thereby precisely adjusting the nozzle height to accommodate the adsorption needs of different sized adhesive components. The horizontally penetrating design of the sliding groove through the vertical cylinder facilitates component installation and adjustment. The structural characteristics of the stepped spline ensure smooth sliding and provide reliable positioning, preventing offset during sliding and improving the mechanism's adjustment accuracy and adaptability.

[0027] Furthermore, the upper housing is also provided with a pressure assembly, which includes a pressure sensor with the sensing surface facing downward and a follower component;

[0028] The follower component includes an annular portion and an extension portion. A second bearing is installed inside the annular portion. The second bearing is sleeved on the second step spline of the stepped spline. In the initial state, the bottom of the follower component is attached to the upper surface of the base.

[0029] The extension is located directly below the pressure sensor, and a pressure spring is provided at the upper end of the extension.

[0030] Through the above technical solution, the coordinated action of the pressure sensor and the follower component in the pressure assembly can sense the pressure changes in real time when the nozzle adsorbs adhesive-coated components. The pressure spring plays an effective buffering role, preventing damage to components due to excessive adsorption pressure or weak adsorption due to insufficient pressure. The annular part of the follower component is sleeved on the stepped spline through a second bearing, ensuring that the follower component can move synchronously with the stepped spline. This makes the pressure sensing data accurate and reliable, providing real-time pressure feedback for the adsorption process. This allows the control system to adjust parameters in a timely manner based on the feedback, ensuring the precision and safety of the adsorption process and meeting the stringent requirements of precision machining of adhesive-coated components.

[0031] Furthermore, a pressure head is connected to the bottom of the through rod, and the bottom of the pressure head is connected to the suction nozzle. The pressure head is composed of an upper sealing plate, a fixing plate, a heating plate, and a lower sealing plate connected from top to bottom.

[0032] Through the above technical solution, the pressure head connected to the bottom of the through rod adopts a combination structure of an upper sealing plate, a fixing plate, a heating plate, and a lower sealing plate. The heating plate can continuously generate stable heat and transfer it to the adhesive components, keeping the adhesive layer on the surface of the components at the optimal working temperature, greatly improving the bonding strength and effectively avoiding quality problems such as weak bonding and detachment caused by unsuitable adhesive layer temperature. The setting of each sealing plate ensures the sealing of the pressure head, reduces heat loss, and improves heating efficiency. The fixing plate enhances the structural stability of the pressure head, prevents deformation of the pressure head during heating or adsorption, and ensures the bonding accuracy between the nozzle and the components, providing a strong guarantee for the smooth progress of subsequent bonding processes.

[0033] Furthermore, an electric slip ring is fitted around the lower middle part of the rotating drum, and the electric slip ring is electrically connected to the heating unit of the heating plate.

[0034] The above technical solution achieves a continuous and stable power supply to the heating plate during rotation, completely solving problems such as wire tangling and breakage caused by rotation, and ensuring the continuity and reliability of the heating function. The design of the electric slip ring does not affect the normal rotation of the drum, ensuring that the heating plate can continuously provide a suitable temperature for the adhesive components while the mechanism is adjusting the angle, maintaining the optimal working state of the adhesive layer. Furthermore, the electric slip ring has a stable connection and excellent conductivity, reducing energy loss and improving the safety and stability of the mechanism's operation.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] (1) The rotary suction nozzle mechanism integrates multiple core functions such as adsorption, rotation, constant temperature heating, and pressure sensing, and specifically solves the key technical problems in the transfer and pasting process of adhesive components. The heating function ensures that the adhesive layer is in the best working state, which significantly improves the adhesion. The synchronous rotation structure driven by the servo motor realizes precise angle adjustment, which perfectly adapts to the installation requirements of irregularly shaped components. The pressure sensing function monitors the adsorption pressure in real time, ensuring the precision and controllability of the adsorption process and avoiding damage to components or adsorption failure. The overall structure is compact and reasonable, and the components work together well. The operation is stable and reliable, which greatly improves the efficiency and quality of processing and assembling adhesive components and effectively reduces the defect rate in the production process.

[0037] (2) The stability of the adsorption negative pressure is ensured by the multi-seal design, the application of the first bearing improves the smoothness of the rotation, the electric slip ring ensures the continuity of heating power supply, and the detachable connection and modular structure design facilitate the maintenance and repair of the equipment. This mechanism can not only meet the processing needs of specific workpieces such as mobile phone adhesive components, but also adapt to different sizes and types of adhesive workpieces by adjusting parameters such as nozzle height and heating temperature, making it highly versatile.

[0048] Example:

[0049] The following is in conjunction with the appendix Figure 1 -6 provides further detailed information about this application.

[0050] This application discloses a rotating suction nozzle mechanism, including:

[0051] The housing includes an upper housing 1 and a lower housing 2;

[0052] A servo motor 3 is provided on the top of the upper housing 1. A first connecting part is provided inside the upper housing 1 and connected to the output shaft of the servo motor 3. A second connecting part is slidably connected below the connecting part. A through pipe 4 is fixedly connected to the bottom of the second connecting part. A through rod 5 and a suction nozzle 6 are connected sequentially from top to bottom.

[0053] The cavity inside the lower housing 2 is a sealed structure. A valve 7 communicating with the cavity is provided on the side of the lower housing 2. A first air hole 8 communicating with the air passage of the cavity is provided on the side of the pipe 4.

[0054] A rotating cylinder 9 is rotatably installed inside the lower housing 2, and a second air hole 10 is transversely opened on the rotating cylinder 9 to communicate with the air passage of the cavity.

[0055] The rotating cylinder 9 extends downward from the lower housing 2, and the top of the rotating cylinder 9 is fixedly connected to the first connecting component;

[0056] The upper parts of the through pipe 4 and the through rod 5 are both located in the rotating drum 9. The lower part of the rotating rod is fitted with a T-shaped central positioning sealing sleeve 11, which is inserted into the bottom of the rotating drum 9.

[0057] See Figures 2-6The lower housing 2 has a first bearing 25 installed on the inner ring of both the upper and lower openings, with the inner ring of the first bearing 25 fitted onto the outside of the rotating cylinder 9. This arrangement of the first bearing 25 on the inner ring of the upper and lower openings of the lower housing 2 and fitted onto the outside of the rotating cylinder 9 effectively reduces the coefficient of friction between the rotating cylinder 9 and the lower housing 2 during rotation, reducing wear between components and significantly extending the overall service life of the mechanism. The bearings also make the rotation of the rotating cylinder 9 smoother, avoiding rotation angle deviations caused by uneven friction, ensuring the positional accuracy of the adhesive-coated components during transport, laying the foundation for precise alignment in subsequent bonding processes, reducing power loss, improving the energy efficiency and stability of the mechanism, and ensuring the reliable execution of precision transport tasks.

[0058] See Figures 2-5 The lower housing 2 has symmetrical annular grooves on its inner wall. At least two coarse sealing rings 12 are fitted onto the rotating cylinder 9. The second vent 10 is located within the distance between the two coarse sealing rings 12. The cooperation between the annular grooves on the inner wall of the lower housing 2 and the coarse sealing rings 12 on the rotating cylinder 9 forms a double-sealing protection structure, greatly enhancing the airtightness of the cavity inside the lower housing 2, effectively preventing gas leakage from the air passage, ensuring the stability of the negative pressure required for adsorption, and preventing adhesive components from falling off during transport due to insufficient adsorption force. Limiting the second vent 10 to the distance between the two coarse sealing rings 12 further optimizes the sealing effect. Furthermore, the annular groove structure facilitates the installation, disassembly, and replacement of the sealing rings, reducing equipment maintenance costs, while not affecting the normal rotation of the rotating cylinder 9, achieving a balance between sealing performance and mechanical flexibility.

[0059] See Figures 2-6 At least two Y-shaped sealing rings 13 are fitted onto the through pipe 4. The first air hole 8 is located within the distance between the two Y-shaped sealing rings 13. The through rod 5, suction nozzle 6, first air hole 8, second air hole 10, coarse sealing ring 12, Y-shaped sealing ring 13, and suction nozzle 6 together form a complete air passage. The Y-shaped sealing ring 13 fitted onto the through pipe 4 and the coarse sealing ring 12 of the lower housing 2 form a multi-seal system, which comprehensively improves the overall sealing reliability of the air passage, ensures a continuous and stable negative pressure for adsorption, provides strong and long-lasting adsorption force for adhesive components, and effectively avoids the problem of workpiece falling off or shifting position due to seal failure during transportation. The complete air passage design makes the gas flow path simple and smooth, reduces airflow resistance, and improves the adsorption response speed. The Y-shaped sealing ring 13 has excellent sealing performance and wear resistance, extends the service life of the sealing components, reduces the frequency of equipment maintenance, and ensures the continuous and stable operation of the mechanism.

[0060] See Figures 2-5The first connecting component has a U-shaped structure, comprising a base 14 and a vertical cylinder 15. The base 14 is larger than the diameter of the rotating cylinder 9 and is detachably connected to the top of the rotating cylinder 9. The integrated design of the base 14 and the vertical cylinder 15 ensures the stability of the connection with the rotating cylinder 9 and provides a stable mounting and sliding platform for the second connecting component. The design of the base 14 being larger than the diameter of the rotating cylinder 9 enhances the load-bearing capacity and stability of the connection. The detachable connection facilitates subsequent inspection and replacement of the components, reducing maintenance difficulty and cost. The structural design of the vertical cylinder 15 and the base 14 improves the overall rigidity of the first connecting component, avoids deformation under stress, and ensures that the power of the servo motor 3 can be accurately transmitted to the rotating cylinder 9 and the second connecting component, guaranteeing the accuracy and stability of the rotational motion.

[0061] See Figure 5 and Figure 6 The first connecting component has a sliding groove 19, which is set downward from the middle and upper part of the vertical cylinder 15 and passes through the base 14. The sliding groove 19 also passes through the vertical cylinder 15 laterally.

[0062] The upper part of the second connecting component is a stepped spline 20 structure, and the lower part is a tubular structure that is fixedly connected to the through pipe 4 and blocks the opening at the top of the tubular structure. The width of the lower part is greater than the width of the slide groove 19.

[0063] The stepped spline 20 is slidably disposed within the slide groove 19, and the outer surface of the first step spline at the top of the stepped spline 20 is threaded. A nut, threaded with the first spline, is fitted onto the outside of the first connecting component. The slide groove 19 of the first connecting component and the stepped spline 20 of the second connecting component are precisely matched, achieving stable sliding of the second connecting component. Its lower tubular structure is fixedly connected to the through pipe 4 and seals the top opening, further ensuring the air passage's sealing. The threaded connection design between the stepped spline 20 and the nut allows for flexible adjustment of the position of the second connecting component, thereby precisely adjusting the height of the suction nozzle 6 to accommodate the adsorption needs of different sized adhesive components. The design of the slide groove 19 horizontally penetrating the vertical cylinder 15 facilitates component installation and adjustment. The structural characteristics of the stepped spline 20 ensure smooth sliding and provide reliable positioning, preventing offset during sliding and improving the adjustment accuracy and adaptability of the mechanism.

[0064] See Figures 2-5 The upper housing 1 is also provided with a pressure assembly, which includes a pressure sensor 16 with the sensing surface facing downward and a follower component 17;

[0065] The follower component 17 includes an annular portion and an extension portion. A second bearing 26 is installed inside the annular portion. The second bearing 26 is sleeved on the second step spline of the stepped spline 20. In the initial state, the bottom of the follower component 17 is in contact with the upper surface of the base 14.

[0066] The extension is located directly below the pressure sensor 16, and a pressure spring is installed at the upper end of the extension. The coordinated action of the pressure sensor 16 and the follower component 17 in the pressure assembly allows for real-time sensing of pressure changes when the nozzle 6 adsorbs adhesive components. The pressure spring provides effective buffering, preventing damage to components due to excessive adsorption pressure or weak adsorption due to insufficient pressure. The annular portion of the follower component 17 is mounted on the stepped spline 20 via a second bearing 26, ensuring synchronized movement between the follower component 17 and the stepped spline 20. This ensures accurate and reliable pressure sensing data, providing real-time pressure feedback for the adsorption process. This allows the control system to adjust parameters promptly based on the feedback, guaranteeing the precision and safety of the adsorption process and meeting the stringent requirements of precision machining of adhesive components.

[0067] See Figures 1-4 The bottom of the through rod 5 is connected to a pressure head, which is connected to a suction nozzle 6. The pressure head is composed of an upper sealing plate 21, a fixing plate 22, a heating plate 23, and a lower sealing plate 24 connected from top to bottom. The pressure head connected to the bottom of the through rod 5 adopts a combination structure of upper sealing plate 21, fixing plate 22, heating plate 23, and lower sealing plate 24. The heating plate 23 can continuously generate stable heat and transfer it to the adhesive components, keeping the adhesive layer on the surface of the components at the optimal working temperature, greatly improving the adhesion and effectively avoiding quality problems such as poor adhesion and detachment caused by unsuitable adhesive layer temperature. The setting of each sealing plate ensures the sealing of the pressure head, reduces heat loss, and improves heating efficiency. The fixing plate 22 enhances the structural stability of the pressure head, prevents deformation of the pressure head during heating or adsorption, and ensures the bonding accuracy between the suction nozzle 6 and the components, providing a strong guarantee for the smooth progress of subsequent bonding processes.

[0068] See Figures 1-4 An electric slip ring 18 is fitted around the lower middle part of the rotating drum 9, and the slip ring 18 is electrically connected to the heating unit of the heating plate 23. This ensures a continuous and stable power supply to the heating plate 23 during rotation, completely solving problems such as wire tangling and breakage caused by rotation, and guaranteeing the continuity and reliability of the heating function. The design of the electric slip ring 18 does not affect the normal rotation of the rotating drum 9, ensuring that the heating plate 23 can continuously provide a suitable temperature for the adhesive components while the mechanism is adjusting the angle, maintaining the optimal working state of the adhesive layer. Furthermore, the electric slip ring 18 has a stable connection and excellent conductivity, reducing power loss and improving the safety and stability of the mechanism's operation.

[0069] The implementation principle of the rotary suction nozzle 6 mechanism in this application embodiment is as follows:

[0070] Before use, the entire device is installed on a drive device such as a robotic arm or linear guide module that can move the device up, down, left, and right in multiple directions. Such devices are existing mature solutions, which can be conceived by those skilled in the art, so they will not be described in detail here.

[0071] After the servo motor 3 is started, it drives the first connecting component to rotate. Since the first connecting component is fixedly connected to the rotating drum 9, and the second connecting component is slidably set in the groove 19 of the first connecting component through the stepped spline 20, the first connecting component will synchronously drive the second connecting component and the rotating drum 9 to rotate together, thereby achieving angle adjustment.

[0072] During the downward pressing process of the device driven by the drive equipment, the stepped spline 20 slides stably along the limited range of the slide groove 19. The slide groove 19 limits the downward pressing stroke, ensuring that the contact distance between the nozzle 6 and the adhesive component is controllable.

[0073] At the same time, the air valve 7 opens to create a negative pressure in the cavity inside the lower housing 2. The negative pressure is transmitted to the through pipe 4 and through rod 5 through the second air hole 10 and the first air hole 8, and finally completes the adsorption of the components through the suction nozzle 6.

[0074] The heating plate 23 generates heat under the continuous power supply of the electric slip ring 18 and transfers it to the components, so that the adhesive layer maintains the optimal working temperature.

[0075] The pressure sensor 16 senses the adsorption pressure in real time through the follower component 17 and feeds it back to the control system to adjust the adsorption force, so as to avoid damage to the components due to improper pressure.

[0076] Once the mechanism rotates to the preset angle and completes precise positioning, the air valve 7 closes, the negative pressure disappears, the suction nozzle 6 releases its components, and the pasting process is successfully completed. Throughout the process, all components work together to ensure precise and efficient operation.

[0077] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
