The filter mesh sleeve 93 is sleeved on the connecting screw 911 and abuts against the upper end of the lower sealing ring 92. The upper gasket 94 is provided on the upper end surface of the filter mesh sleeve 93. The lower end of the upper cover 96 is provided with a screw thread 911 for connecting the connecting screw 911. The connecting sleeve 961 cooperates with the rod 911, and a clamping groove 962 for clamping the upper sealing ring 95 is provided at the periphery of the upper cover 96.

The upper cover 96 is sealed with the cup body 91 through the upper sealing ring 95. The filter mesh sleeve 93 is sealed with the upper cover 96 through the upper gasket 94. The upper cover 96 is provided with an inlet 963 and an outlet 964.

[0003] Assembly is a critical and complex step in the manufacturing process of these filters. Traditional filter assembly methods rely primarily on manual labor, which presents numerous drawbacks. From a production efficiency perspective, manual assembly is limited in speed, requiring each worker to complete a single filter assembly over a considerable period of time, and it is difficult to maintain a steady work pace over a long period of time. This results in low overall production efficiency and an inability to meet the demands of large-scale production. Furthermore, manual labor is susceptible to factors such as the operator's skill level and fatigue level, affecting assembly quality.

[0004] In order to solve the above problems, a filter assembly machine is urgently needed to improve the production efficiency and quality of the filter and reduce the production cost. Summary of the Invention

[0005] Therefore, in order to solve the above problems, the present invention proposes a filter assembly machine, which solves the technical problems of low production efficiency, unstable quality and high production cost in the existing filter assembly. A filter assembly method is also proposed.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A filter assembly machine is used to assemble a filter, the filter comprising a cup body, a lower sealing ring, a filter mesh sleeve, an upper gasket, an upper sealing ring, and an upper cover. A connecting screw is provided on an upwardly protruding middle portion of the cup body. The filter assembly machine comprises a frame and a conveying mechanism provided on the frame. The frame is provided with a first input mechanism for inputting the cup body, a second input mechanism for inputting the lower sealing ring, a third input mechanism for inputting the filter sleeve, a fourth input mechanism for inputting the upper gasket, a fifth input mechanism for inputting the upper sealing ring, and a sixth input mechanism for inputting the upper cover on both sides of the conveying mechanism; The frame is respectively provided with a first transfer mechanism for transferring the cup body on the first input mechanism to the conveying mechanism, a second transfer mechanism for sleeve the lower sealing ring on the connecting screw, a third transfer mechanism for sleeve the filter sleeve on the connecting screw, and a fourth transfer mechanism for transferring the upper gasket to the upper end of the filter sleeve; The frame is provided with an upper cover transfer and installation mechanism, which includes a transverse moving rod, a transverse seat sliding along the transverse moving rod, a transverse driving mechanism driving the transverse seat to move, a lifting seat provided on the transverse seat so as to be able to be raised and lowered, a lifting driving mechanism provided on the transverse seat to drive the lifting seat, a clamping mechanism provided at the lower end of the lifting driving mechanism, and a transmission driving mechanism driving the clamping mechanism to rotate; The frame is provided with an upper sealing ring assembly mechanism, which includes a tapered sleeve rod for positioning the upper sealing ring, a lifting ring body provided on the outer circumference of the tapered sleeve rod, and a lifting drive mechanism for driving the lifting ring body to rise. The frame is provided with a fifth transfer mechanism for sleeve-mounting the upper sealing ring body on the tapered sleeve rod; The upper cover transfer and installation mechanism can move back and forth between the upper sealing ring assembly mechanism, the sixth input mechanism and the conveying mechanism to achieve the grabbing of the upper cover, the assembly of the upper cover and the upper sealing ring, and the assembly of the upper cover and the cup body.

[0007] Furthermore, the conveying mechanism is an annular conveyor belt, the surface of which is provided with positioning grooves for positioning the cup body.

[0008] Furthermore, the first transfer mechanism, the second transfer mechanism, the third transfer mechanism, the fourth transfer mechanism and the fifth transfer mechanism are multi-axis robots or rectangular coordinate systems.

[0009] Furthermore, the second input mechanism and the fourth input mechanism include a material selection ring rotatably arranged on the frame, a material selection driving mechanism for driving the material selection ring to rotate, a material receiving inclined plate arranged at the center of the material selection ring, a material conveying plate connected to the material receiving inclined plate, and a vibration mechanism arranged at the lower end of the material conveying plate. A plurality of material selection plates are arranged on the inner side wall of the material selection ring in a radial direction. The material receiving inclined plate is inclined toward one side of the material selection plate to form an inclined surface for facilitating material receiving. A blocking surface is arranged on the material receiving inclined plate perpendicular to the inclined surface. The material receiving inclined plate and the material conveying plate are inclined from the input end to the output end, and the inclination angle is 5°-20°.

[0010] Furthermore, a feeding trough is provided on the feeding plate.

[0011] Furthermore, the inclination angle of the inclined surface is 20°-60°.

[0012] Furthermore, the material selection drive mechanism includes a material selection bracket, two or more transmission rollers rotatably arranged on the material selection bracket and a transmission drive mechanism, the material selection ring is clamped between the transmission rollers to realize rotational drive, at least one transmission roller is connected to the transmission drive mechanism, and the vibration mechanism is connected to the material selection bracket to realize vibration transmission.

[0013] Furthermore, the clamping mechanism and the transmission drive mechanism are connected via a pneumatic slip ring, and the pneumatic slip ring is provided on the lifting seat to realize air supply in a rotating state.

[0014] Based on the same inventive concept, a filter assembly method is also proposed, which is applied to the above-mentioned filter assembly machine and includes the following steps: Cup body input step: inputting the cup body through the first input mechanism, and then transferring the cup body to the positioning groove on the conveying mechanism by the first transfer mechanism; Lower sealing ring installation steps: the second input mechanism inputs the lower sealing ring, and the second transfer mechanism sleeves the lower sealing ring onto the connecting screw of the cup body; Filter sleeve installation steps: the third input mechanism inputs the filter sleeve, and the third transfer mechanism sleeves the filter sleeve onto the connecting screw of the cup body; Upper gasket installation steps: the fourth input mechanism inputs the upper gasket, and the fourth transfer mechanism transfers the upper gasket to the upper end of the filter sleeve; Upper sealing ring assembly steps: the fifth input mechanism inputs the upper sealing ring, and the fifth transfer mechanism sleeves the upper sealing ring onto the tapered sleeve rod; Upper cover installation steps: The sixth input mechanism inputs the upper cover, the upper cover transfer and installation mechanism transfers the upper cover to the top of the conical sleeve rod, the lifting drive mechanism presses downward so that the upper cover is pressed against the upper end of the conical sleeve rod, the jacking drive mechanism drives the jacking ring to rise, so that the upper sealing ring is clamped on the upper cover, and the upper cover is transferred to the top of the cup body on the conveying mechanism, the lifting drive mechanism presses downward so that the upper cover is pressed against the connecting screw of the cup body, and the transmission drive mechanism drives the clamping mechanism to rotate the upper cover to connect with the connecting screw, thereby realizing assembly.

[0015] Furthermore, when the second input mechanism or the fourth input mechanism transports the lower sealing ring or the upper gasket, intermittent vibration is added, and when the lower sealing ring or the upper gasket is located at the picking position, the vibration stops.

[0016] By adopting the above technical solution, the beneficial effects of the present invention are: 1. This filter assembly machine integrates multiple input and transfer mechanisms, capable of simultaneously handling the input and assembly of multiple components, including the cup body, lower sealing ring, filter screen, upper gasket, upper sealing ring, and upper cover. Each process can be performed in parallel or in an orderly fashion. Compared with traditional manual assembly or single-process assembly equipment, this greatly shortens the assembly cycle and significantly improves the overall assembly efficiency of the filter. Each transfer and assembly mechanism can operate precisely according to preset procedures and parameters, reducing the errors and instabilities that may be caused by manual operation, thereby ensuring the quality and consistency of filter assembly and improving the product's pass rate. The entire assembly process is completed automatically by the machine, eliminating the need for extensive human intervention, reducing reliance on manual skills and production fluctuations caused by human factors, and facilitating large-scale, standardized automated production, thereby reducing production costs.

[0017] 2. The positioning grooves on the surface of the endless conveyor belt provide precise positioning for the cup body, ensuring that the cup body maintains a stable position and posture during transportation. This facilitates the subsequent transfer mechanisms to accurately install other components on the cup body, improving the accuracy and reliability of assembly. The positioning grooves can limit the movement of the cup body during transportation, preventing the cup body from shifting due to vibration or collision during transportation, thereby ensuring the smooth progress of the assembly process and reducing the defective products caused by cup body displacement.

[0018] 3. Multi-axis robots or rectangular coordinate systems have multiple degrees of freedom, enabling flexible and precise movement within three-dimensional space. They can quickly and accurately complete transfer tasks based on the shape, size, and installation location requirements of different components, adapting to the assembly needs of various filter specifications. Both mechanisms have high positioning accuracy, ensuring that each component is accurately transferred to the target position, improving assembly accuracy and quality, and reducing quality issues caused by component installation position deviations.

[0019] 4. The selection ring and plate enable orderly screening and arrangement of incoming components (such as lower sealing rings or upper gaskets), ensuring they enter the subsequent conveying process in a defined order and direction. This prevents component clutter and accumulation, and improves selection efficiency. The inclined and blocking surfaces of the receiving inclined plate ensure smooth and stable delivery of components into the receiving area, preventing them from falling or rebounding during the receiving process, ensuring accurate and stable material handling. The combined use of the feed plate and vibration mechanism ensures that components are evenly and orderly conveyed forward on the feed plate through vibration, preventing blockage and jamming during the feeding process and improving feeding efficiency and reliability.

[0020] 5. The conveyor trough can limit the lateral movement of the parts during the conveying process, so that the parts are conveyed forward along a fixed track, preventing the parts from deviating from the conveying direction due to vibration or other reasons, ensuring that the parts can accurately reach the picking position, facilitating the subsequent transfer mechanism to grab.

[0021] 6. Setting the inclination angle of the inclined surface to 20°-60° can provide a suitable splicing angle according to the shape and size of different parts, so that the parts can slide smoothly into the splicing area. At the same time, it can avoid the parts from sliding down too fast and popping out due to a large inclination angle, or the parts from not sliding down smoothly due to a small inclination angle, thereby optimizing the splicing effect.

[0022] 7. The material selection drive mechanism, through the cooperation of the transmission roller and the transmission drive mechanism, can stably and reliably drive the material selection ring to rotate, ensuring that the material selection plate can select materials at the predetermined speed and rhythm, improving the accuracy and stability of material selection. The vibration mechanism is connected to the material selection bracket and can effectively transmit vibration to the material feeding plate and material selection ring, so that the components are evenly vibrated during the conveying and material selection process, ensuring uniform feeding and smooth material selection.

[0023] 8. The pneumatic slip ring ensures a continuous and stable air supply to the clamping mechanism during rotation, ensuring the proper functioning of its pneumatic components (such as cylinders). This enables reliable clamping and release operations while the clamping mechanism is rotating, improving the performance and reliability of the cover transfer and installation mechanism. The pneumatic slip ring effectively isolates and connects the air supply pipeline with the rotating components, avoiding structural complexity and failures caused by pipeline entanglement and other issues. It simplifies the equipment's structural layout and facilitates installation, maintenance, and commissioning.

[0024] 9. This assembly method describes each step of filter assembly in detail, from cup body input to lid installation, forming a complete and systematic assembly process. The close connection and clear logic between each step facilitate automated production and quality control, ensuring that each assembly link is operated in accordance with standard requirements. Through clear steps and operational requirements, uncertainty and human error in the assembly process are reduced, making the assembly process more standardized and efficient, enabling the filter assembly task to be completed quickly and accurately, improving assembly efficiency and product quality.

[0025] 10. Intermittent vibration keeps the lower sealing ring or upper gasket loose during transport, preventing components from sticking to each other due to prolonged static conditions. This ensures that each component reaches the pickup position individually and smoothly, facilitating accurate grasping by the transfer mechanism. Stopping vibration when the lower sealing ring or upper gasket is at the pickup position stabilizes the component at the moment of pickup, reducing component position shifting caused by vibration. This improves the accuracy and reliability of the transfer mechanism's grasping of components and ensures smooth assembly. BRIEF DESCRIPTION OF THE DRAWINGS

The frame 1 is provided with a first transfer mechanism 41 for transferring the cup body (91) on the first input mechanism 31 to the conveying mechanism 2, a second transfer mechanism 42 for sleeve-mounting the lower sealing ring 92 on the connecting screw 911, a third transfer mechanism 43 for sleeve-mounting the filter mesh sleeve 93 on the connecting screw 911, and a fourth transfer mechanism 44 for transferring the upper gasket 94 to the upper end of the filter mesh sleeve 93; The frame 1 is provided with an upper cover transfer and installation mechanism 5, which includes a transverse moving rod 51, a transverse seat 52 sliding along the transverse moving rod 51, a transverse driving mechanism 53 driving the transverse seat 52 to move, a lifting seat 54 provided on the transverse seat 52 so as to be able to rise and fall, a lifting driving mechanism 55 provided on the transverse seat 52 and driving the lifting seat 54, a clamping mechanism 56 provided at the lower end of the lifting driving mechanism 55, and a transmission driving mechanism 57 driving the clamping mechanism 56 to rotate; The frame 1 is provided with an upper sealing ring assembly mechanism 6, which includes a tapered sleeve rod 61 for positioning the upper sealing ring 95, a lifting ring body 62 provided on the outer circumference of the tapered sleeve rod 61, and a lifting drive mechanism 63 for driving the lifting ring body 62 to rise. The frame 1 is provided with a fifth transfer mechanism 45 for sleeve-mounting the upper sealing ring 95 on the tapered sleeve rod 61; The upper cover transfer and installation mechanism 5 can move back and forth between the upper sealing ring assembly mechanism 6 , the sixth input mechanism 36 and the conveying mechanism 2 to achieve the grabbing of the upper cover 96 , the assembly of the upper cover 96 with the upper sealing ring 95 , and the assembly of the upper cover 96 with the cup body 91 .

[0037] The first transfer mechanism 41 , the second transfer mechanism 42 , the third transfer mechanism 43 , the fourth transfer mechanism 44 and the fifth transfer mechanism 45 are multi-axis robots or rectangular coordinate systems.

[0038] The second and fourth input mechanisms 32 and 34 include a material selection ring 71 rotatably mounted on the frame 1, a material selection drive mechanism 72 for rotating the material selection ring 71, a material receiving inclined plate 73 located at the center of the material selection ring 71, a material conveying plate 74 connected to the material receiving inclined plate 73, and a vibration mechanism 75 located at the lower end of the material conveying plate 74. The material selection ring 71 is provided with a plurality of material selection plates 711 radially disposed on the inner sidewall. The material receiving inclined plate 73 is tilted toward one side of the material selection plate 711 to form an inclined surface 731 for facilitating material receiving. The material receiving inclined plate 73 is provided with a blocking surface 732 perpendicular to the inclined surface 731. The material receiving inclined plate 73 and the material conveying plate 74 are inclined from the input end to the output end at an angle of 5°-20°. The material conveying plate 74 is provided with a material conveying trough 741. The inclined surface 731 has an inclination angle of 20°-60°. The material selection drive mechanism 72 includes a material selection bracket 721, two or more transmission rollers 722 rotatably arranged on the material selection bracket 721, and a transmission drive mechanism 57. The material selection ring 71 is clamped between the transmission rollers 722 to realize rotational drive. At least one transmission roller 722 is connected to the transmission drive mechanism 57 for transmission. The vibration mechanism 75 is connected to the material selection bracket 721 to realize vibration transmission.

[0039] The transmission rollers 722 can rotate in either forward or reverse direction, and multiple transmission rollers 722 can rotate in the same direction.

[0040] The remaining first input mechanism 31 , third input mechanism 33 , fifth input mechanism 35 , and sixth input mechanism 36 can all be transported using conventional conveyor belts.

[0041] The clamping mechanism 56 and the transmission driving mechanism 57 are connected via a pneumatic slip ring 58 . The pneumatic slip ring 58 is provided on the lifting seat 54 to realize air supply in a rotating state.

[0042] The conveying mechanism 2 is an annular conveyor belt, the purpose of which is to realize the circular conveying of the cup body. It can be set according to actual needs. A positioning groove 21 for positioning the cup body 91 is provided on its surface. The positioning groove 21 can also be used to limit the rotation of the cup body 91, thereby cooperating with the transmission drive mechanism 57 for the rotation of the upper cover 96, thereby realizing effective locking between the upper cover 96 and the cup body 91.

[0043] The transmission roller 722 of the material selection drive mechanism 72 can be a rubber-coated steel roller to increase the friction between the material selection ring 71. The transmission drive mechanism 57 can be a reduction motor or other conventional motor. The vibration mechanism 75 can be an electromagnetic vibrator or other vibration equipment to generate uniform vibration.

[0044] The conveying trough 741 can limit the lateral movement of the components during the conveying process, so that the components are conveyed forward along a fixed track.

[0045] In actual applications, various sensors, such as photoelectric sensors, can be set up for position detection. In this solution, the first transfer mechanism 41 to the fifth transfer mechanism 45 all adopt rectangular coordinate system mechanisms, and of course they can also be multi-axis robots. The lateral drive mechanism 53 and the lifting drive mechanism 55 of the upper cover transfer and installation mechanism 5 can adopt stepper motors, which have the characteristics of high control accuracy and stable operation. The clamping mechanism 56 can adopt pneumatic clamps to achieve clamping and releasing actions through the pneumatic system. The lifting drive mechanism 63 of the upper sealing ring assembly mechanism 6 can adopt an electric push rod, which can provide a stable lifting force. Of course, the above-mentioned driving methods can all be replaced by well-known similar mechanisms.

[0046] A filter assembly method comprises the following steps: Cup body input step: the cup body 91 is input through the first input mechanism 31, and then the first transfer mechanism 41 transfers the cup body 91 to the positioning groove 21 on the conveying mechanism 2; Lower sealing ring installation step: the second input mechanism 32 inputs the lower sealing ring 92, and the second transfer mechanism 42 sleeves the lower sealing ring 92 onto the connecting screw 911 of the cup body 91; Filter cover installation step: The third input mechanism 33 inputs the filter cover 93, and the third transfer mechanism 43 sleeves the filter cover 93 onto the connecting screw 911 of the cup body 91; Upper gasket installation step: the fourth input mechanism 34 inputs the upper gasket 94, and the fourth transfer mechanism 44 transfers the upper gasket 94 to the upper end of the filter sleeve 93; Upper sealing ring assembly steps: The fifth input mechanism 35 inputs the upper sealing ring 95, and the fifth transfer mechanism 45 sleeves the upper sealing ring 95 onto the tapered sleeve rod 61; Upper cover installation steps: the sixth input mechanism 36 inputs the upper cover 96, the upper cover transfer and installation mechanism 5 transfers the upper cover 96 to above the conical sleeve rod 61, the lifting drive mechanism 55 presses downward so that the upper cover 96 is pressed against the upper end of the conical sleeve rod 61, the lifting drive mechanism 63 drives the lifting ring body 62 to rise, so that the upper sealing ring 95 is clamped on the upper cover 96, and the upper cover 96 is transferred to above the cup body 91 on the conveying mechanism 2, the lifting drive mechanism 55 presses downward so that the upper cover 96 is pressed against the connecting screw 911 of the cup body, and the transmission drive mechanism 57 drives the clamping mechanism 56 to rotate the upper cover 96 to achieve connection with the connecting screw 911, thereby realizing assembly.

[0047] When the second input mechanism 32 or the fourth input mechanism 34 transports the lower sealing ring 92 or the upper gasket 94 , intermittent vibration is added, and when the lower sealing ring 92 or the upper gasket 94 is located at the picking position, the vibration stops.

[0048] This filter assembly method describes each step in detail, forming a complete and systematic assembly process. By clearly defining the steps and operational requirements, it reduces uncertainty and human error during the assembly process, making it more standardized and efficient. The steps are tightly linked and logically coherent, enabling automated production and quality control. Following this method, filter assembly can be completed quickly and accurately, improving assembly efficiency and product quality while reducing production costs.

[0049] Intermittent vibration can keep the lower sealing ring 92 or the upper gasket 94 in a loose state during transportation, avoiding the adhesion between components due to long-term static conditions. By reasonably setting the vibration frequency, duration, and stop time, the vibration of the lower sealing ring 92 or the upper gasket 94 stops when it is in the picking position, which can keep the component in a stable state at the moment of picking up and reduce the position deviation of the component caused by vibration. In this way, the accuracy and reliability of the first transfer mechanism 41, the second transfer mechanism 42, the third transfer mechanism 43, the fourth transfer mechanism 44, and the fifth transfer mechanism 45 in grasping the component can be improved, ensuring the smooth progress of the assembly process, reducing production failures and defective rates caused by component grasping problems, and improving production efficiency and product quality.

[0050] Although the present invention has been particularly shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the present invention.
