Description

Technical Field

[0001] This invention relates to the field of filter assembly, and more particularly to a filter assembly machine and its assembly method. Background Technology

[0002] Currently, there is a filter, reference Figure 6 , Figure 7 , Figure 8 As shown, it includes a cup body 91, a lower sealing ring 92, a filter screen sleeve 93, an upper gasket 94, an upper sealing ring 95, and an upper cover 96. A connecting screw 911 protrudes upward from the center of the cup body 91. The lower sealing ring 92 is fitted around the lower end of the connecting screw 911. The filter screen sleeve 93 is fitted onto the connecting screw 911 and abuts against the upper end of the lower sealing ring 92. The upper gasket 94 is disposed on the upper surface of the filter screen sleeve 93. The lower end of the upper cover 96 is provided with a connection point to the connecting screw. The upper cover 96 has a connecting screw sleeve 961 that engages with the rod 911. The upper cover 96 has a locking groove 962 around its periphery for locking the upper sealing ring 95. The upper cover 96 is connected to the cup body 91 by the connecting screw sleeve 961 engaging with the connecting screw rod 911. The upper cover 96 is sealed to the cup body 91 by the upper sealing ring 95. The filter screen sleeve 93 is sealed to the upper cover 96 by the upper gasket 94. The upper cover 96 has an inlet 963 and an outlet 964.

[0003] Assembly is a crucial and complex step in the manufacturing process of this type of filter. Traditional filter assembly methods mainly rely on manual operation, which has many drawbacks. In terms of production efficiency, manual assembly has limited speed; each worker needs a considerable amount of time to assemble one filter, and it is difficult to maintain a stable work rhythm for extended periods, resulting in low overall production efficiency and failing to meet the demands of large-scale production. Regarding assembly quality, manual operation is easily affected by factors such as the operator's skill level and fatigue level.

[0004] To address the aforementioned issues, there is an urgent need for a filter assembly machine to improve filter production efficiency and quality while reducing production costs. Summary of the Invention

[0005] Therefore, to address the aforementioned problems, this invention proposes a filter assembly machine, which solves the technical problems of low production efficiency, unstable quality, and high production costs in existing filter assembly processes. A filter assembly method is also proposed accordingly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A filter assembly machine is used to assemble a filter, the filter including a cup body, a lower sealing ring, a filter screen sleeve, an upper gasket, an upper sealing ring and an upper cover, a connecting screw is provided with an upward protrusion in the middle of the cup body, and the filter assembly machine includes a frame and a conveying mechanism provided on the frame;

[0008] The frame is provided with a first input mechanism for cup body input, a second input mechanism for lower sealing ring input, a third input mechanism for filter screen sleeve input, a fourth input mechanism for upper gasket input, a fifth input mechanism for upper sealing ring input, and a sixth input mechanism for upper cover input on both sides of the conveying mechanism.

[0009] 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 fitting the lower sealing ring onto the connecting screw, a third transfer mechanism for fitting the filter screen onto the connecting screw, and a fourth transfer mechanism for transferring the upper gasket to the upper end of the filter screen.

[0010] The frame is provided with a top cover transfer and installation mechanism, which includes a transverse moving rod, a transverse seat that slides along the transverse moving rod, a transverse driving mechanism that drives the transverse seat to move, a lifting seat that can be raised and lowered on the transverse seat, a lifting driving mechanism that drives the lifting seat on the transverse seat, a clamping mechanism at the lower end of the lifting driving mechanism, and a transmission driving mechanism that drives the clamping mechanism to rotate.

[0011] The frame is provided with an upper sealing ring assembly mechanism, which includes a tapered sleeve for positioning the upper sealing ring, a lifting ring body provided on the outer circumference of the tapered sleeve, and a lifting drive mechanism for driving the lifting ring body to rise. The frame is also provided with a fifth transfer mechanism for fitting the upper sealing ring body onto the tapered sleeve.

[0012] 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 realize the gripping 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.

[0013] Furthermore, the conveying mechanism is an annular conveyor belt with positioning grooves for positioning cups on its surface.

[0014] 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 Cartesian coordinate system mechanisms.

[0015] Furthermore, the second and fourth input mechanisms include a material selection ring rotatably mounted on the frame, a material selection drive mechanism for driving the material selection ring to rotate, a receiving inclined plate located at the center of the material selection ring, a conveying plate connected to the receiving inclined plate, and a vibration mechanism located at the lower end of the conveying plate. Multiple material selection plates are arranged radially on the inner sidewall of the material selection ring. The receiving inclined plate is inclined to one side facing the material selection plate to form an inclined surface that facilitates material reception. A blocking surface is provided on the receiving inclined plate perpendicular to the inclined surface. The receiving inclined plate and the conveying plate are inclined from the input end to the output end, with an inclination angle of 5°-20°.

[0016] Furthermore, a feeding trough is provided on the feeding plate.

[0017] Furthermore, the tilt angle of the inclined surface is 20°-60°.

[0018] Furthermore, the material selection drive mechanism includes a material selection bracket, two or more transmission rollers rotatably mounted on the material selection bracket, and a transmission drive mechanism. The material selection ring is clamped between each transmission roller to achieve rotational drive. At least one transmission roller is connected to the transmission drive mechanism. The vibration mechanism is connected to the material selection bracket to achieve vibration transmission.

[0019] Furthermore, the clamping mechanism is connected to the transmission drive mechanism via a pneumatic slip ring, which is mounted on the lifting seat to provide air supply during rotation.

[0020] Based on the same inventive concept, a filter assembly method is also proposed, applied to the aforementioned filter assembly machine, comprising the following steps:

[0021] Cup input steps: The cup is input through the first input mechanism, and then the cup is transferred to the positioning groove on the conveying mechanism by the first transfer mechanism;

[0022] Lower sealing ring installation steps: The second input mechanism inputs the lower sealing ring, and the second transfer mechanism places the lower sealing ring onto the connecting screw of the cup body;

[0023] Filter sleeve installation steps: The third input mechanism inputs the filter sleeve, and the third transfer mechanism places the filter sleeve onto the connecting screw of the cup body;

[0024] 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 screen sleeve;

[0025] Upper sealing ring assembly steps: The fifth input mechanism inputs the upper sealing ring, and the fifth transfer mechanism places the upper sealing ring onto the tapered sleeve rod;

[0026] Top cover installation steps: The sixth input mechanism inputs the top cover, the top cover transfer and installation mechanism transfers the top cover to above the conical sleeve rod, the lifting drive mechanism presses downward so that the top cover presses against the upper end of the conical sleeve rod, the lifting drive mechanism drives the lifting ring to rise so that the upper sealing ring is placed on the top cover, the top cover is transferred to above the cup body on the conveying mechanism, the lifting drive mechanism presses downward so that the top cover presses against the connecting screw of the cup body, the transmission drive mechanism drives the clamping mechanism to rotate the top cover to achieve connection with the connecting screw, thereby realizing assembly.

[0027] Furthermore, when the second or fourth input mechanism delivers the lower sealing ring or the upper gasket, intermittent vibration is added, and the vibration stops when the lower sealing ring or the upper gasket is in the pickup position.

[0028] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:

[0029] 1. This filter assembly machine integrates multiple input and transfer mechanisms, enabling simultaneous input and assembly of various components such as the cup body, lower sealing ring, filter screen sleeve, upper gasket, upper sealing ring, and upper cover. Each process can be performed in parallel or sequentially. Compared to traditional manual assembly or single-process assembly equipment, this significantly shortens the assembly cycle and dramatically improves the overall assembly efficiency of the filter. Each transfer and assembly mechanism operates precisely according to preset programs and parameters, reducing errors and instability that may arise from manual operation. This ensures the quality and consistency of filter assembly and improves product qualification rates. The entire assembly process is completed automatically by the machine, requiring minimal human intervention. This reduces reliance on manual skills and minimizes production fluctuations caused by human factors, facilitating large-scale, standardized automated production and reducing production costs.

[0030] 2. The positioning grooves on the surface of the circular conveyor belt provide precise positioning for the cup, ensuring that the cup maintains a stable position and posture during conveying. This facilitates the accurate installation of other components onto the cup by subsequent transfer mechanisms, improving the accuracy and reliability of assembly. The positioning grooves restrict the movement of the cup during conveying, preventing positional shifts caused by vibrations or collisions, thus ensuring smooth assembly and reducing defects caused by cup displacement.

[0031] 3. Multi-axis robots or Cartesian coordinate systems possess multiple degrees of freedom, enabling flexible and precise movement in three-dimensional space. They can quickly and accurately complete transfer tasks based on the shape, size, and installation position requirements of different components, adapting to the assembly needs of various filter specifications. Both types of mechanisms have high positioning accuracy, ensuring that each component is accurately transferred to the target position, improving assembly precision and quality, and reducing quality problems caused by component installation position deviations.

[0032] 4. The selection ring and selection plate enable the orderly screening and arrangement of input components (such as lower sealing rings or upper gaskets), allowing components to enter the subsequent conveying process in a specific order and direction. This avoids component confusion and accumulation, improving selection efficiency. The inclined surface and blocking surface design of the receiving tilting plate ensure that components fall smoothly and stably into the receiving area, preventing components from falling or bouncing during the receiving process, thus guaranteeing the accuracy and stability of receiving. The combined use of the conveying plate and vibration mechanism uses vibration to transport components forward evenly and orderly on the conveying plate, avoiding blockages and jams during the conveying process, and improving conveying efficiency and reliability.

[0033] 5. The feeding trough can limit the lateral movement of the parts during the feeding 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, which is convenient for the subsequent transfer mechanism to grab.

[0034] 6. Setting the tilt angle of the inclined surface to 20°-60° can provide a suitable receiving angle according to the shape and size of different parts, so that the parts can slide smoothly into the receiving area. At the same time, it avoids the parts from popping out due to excessively large tilt angle or the parts not sliding smoothly due to insufficient tilt angle, thus optimizing the receiving effect.

[0035] 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 perform material selection operations at a predetermined speed and rhythm, thus improving the accuracy and stability of material selection. The vibration mechanism is connected to the material selection bracket, which can effectively transmit vibration to the conveying plate and the material selection ring, so that the components are subjected to uniform vibration during the conveying and material selection process, ensuring the uniformity of material conveying and the smoothness of material selection.

[0036] 8. The pneumatic slip ring ensures a continuous and stable air supply to the clamping mechanism during rotation, guaranteeing the normal operation of its pneumatic components (such as cylinders). This enables reliable clamping and releasing operations during rotation, improving the performance and reliability of the top cover transfer and installation mechanism. The pneumatic slip ring effectively isolates and connects the air supply pipeline to the rotating parts, avoiding structural complexity and malfunctions caused by pipeline entanglement, simplifying the equipment's structural layout, and facilitating installation, maintenance, and debugging.

[0037] 9. This assembly method details each step of the filter assembly process, from cup input to top cover installation, forming a complete and systematic assembly flow. The steps are closely linked and logically clear, facilitating automated production and quality control, ensuring that each assembly stage is performed according to standard requirements. Clear steps and operational requirements reduce uncertainties and human error during assembly, making the process more standardized and efficient. This allows for quick and accurate completion of the filter assembly task, improving assembly efficiency and product quality.

[0038] 10. Intermittent vibration keeps the lower sealing ring or upper gasket loose during transport, preventing components from sticking together due to prolonged stillness. This ensures each component reaches the pickup position independently and smoothly, facilitating accurate gripping by the transfer mechanism. Vibration stops when the lower sealing ring or upper gasket is in the pickup position, maintaining stability at the moment of pickup and reducing component positional shifts caused by vibration. This improves the accuracy and reliability of the transfer mechanism's gripping of components, ensuring smooth assembly. Attached Figure Description

[0049] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0050] refer to Figures 1 to 8 As shown, this embodiment provides a filter assembly machine for assembling filters. The structure of the filter is described in detail in the background art and will not be repeated here. The filter assembly machine includes a frame 1 and a conveying mechanism 2 disposed on the frame 1;

[0051] The frame 1 is provided with a first input mechanism 31 for inputting the cup body 91, a second input mechanism 32 for inputting the lower sealing ring 92, a third input mechanism 33 for inputting the filter screen sleeve 93, a fourth input mechanism 34 for inputting the upper gasket 94, a fifth input mechanism 35 for inputting the upper sealing ring 95, and a sixth input mechanism 36 for inputting the upper cover 96 on both sides of the conveying mechanism 2.

[0052] The frame 1 is respectively provided with a first transfer mechanism 41 for transferring the cup (91) on the first input mechanism 31 to the conveying mechanism 2, a second transfer mechanism 42 for fitting the lower sealing ring 92 onto the connecting screw 911, a third transfer mechanism 43 for fitting the filter screen sleeve 93 onto the connecting screw 911, and a fourth transfer mechanism 44 for transferring the upper gasket 94 to the upper end of the filter screen sleeve 93;

[0053] The frame 1 is provided with a top cover transfer and installation mechanism 5. The top cover transfer and installation mechanism 5 includes a transverse moving rod 51, a transverse seat 52 that slides along the transverse moving rod 51, a transverse driving mechanism 53 that drives the transverse seat 52 to move, a lifting seat 54 that can be raised and lowered on the transverse seat 52, a lifting driving mechanism 55 that drives the lifting seat 54 on the transverse seat 52, a clamping mechanism 56 that is located at the lower end of the lifting driving mechanism 55, and a transmission driving mechanism 57 that drives the clamping mechanism 56 to rotate.

[0054] The frame 1 is provided with an upper sealing ring assembly mechanism 6. The upper sealing ring assembly mechanism 6 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 fitting the upper sealing ring 95 onto the tapered sleeve rod 61.

[0055] 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 realize the gripping of the upper cover 96, the assembly of the upper cover 96 and the upper sealing ring 95 and the assembly of the upper cover 96 and the cup body 91.

[0056] 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 Cartesian coordinate system mechanisms.

[0057] The second input mechanism 32 and the fourth input mechanism 34 include a material selection ring 71 rotatably mounted on the frame 1, a material selection drive mechanism 72 for driving the material selection ring 71 to rotate, a receiving inclined plate 73 located at the center of the material selection ring 71, a conveying plate 74 connected to the receiving inclined plate 73, and a vibration mechanism 75 located at the lower end of the conveying plate 74. Multiple material selection plates 711 are arranged radially on the inner wall of the material selection ring 71. The receiving inclined plate 73 is inclined towards one side of the material selection plate 711 to form an inclined surface 731 for easy material reception. A blocking surface 732 is provided on the receiving inclined plate 73 perpendicular to the inclined surface 731. The receiving inclined plate 73 and the conveying plate 74 are inclined from the input end to the output end at an angle of 5°-20°. A conveying trough 741 is provided on the conveying plate 74. The inclination angle of the inclined surface 731 is 20°-60°. The material selection drive mechanism 72 includes a material selection bracket 721, two or more transmission rollers 722 rotatably mounted on the material selection bracket 721, and a transmission drive mechanism 57. The material selection ring 71 is clamped between each transmission roller 722 to achieve rotation 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 achieve vibration transmission.

[0058] The aforementioned drive roller 722 can rotate in either forward or reverse direction, and multiple drive rollers 722 can rotate in the same direction.

[0059] 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.

[0060] The clamping mechanism 56 is connected to the transmission drive mechanism 57 via a pneumatic slip ring 58, which is mounted on the lifting seat 54 to supply air during rotation.

[0061] The conveying mechanism 2 is a ring conveyor belt, which is used to realize the cyclic conveying of the cup. It can be set according to actual needs. Its surface is provided with a positioning groove 21 for positioning the cup 91. The positioning groove 21 can also be used to limit the rotation of the cup 91, so as to cooperate with the transmission drive mechanism 57 to rotate the upper cover 96, thereby realizing the effective locking between the upper cover 96 and the cup 91.

[0062] The transmission roller 722 of the material selection drive mechanism 72 can be a rubber-coated steel roller to increase the friction between it and the material selection ring 71. The transmission drive mechanism 57 can be a geared motor or other conventional motor. The vibration mechanism 75 can be an electromagnetic vibrator or other vibration equipment capable of generating uniform vibration.

[0063] The feed trough 741 can restrict the lateral movement of the component during the feeding process, so that the component is conveyed forward along a fixed track.

[0064] In practical applications, various sensors, such as photoelectric sensors, can be used for position detection. In this scheme, the first transfer mechanism 41 to the fifth transfer mechanism 45 all adopt a Cartesian coordinate system mechanism, but a multi-axis robot could also be used. The lateral drive mechanism 53 and the lifting drive mechanism 55 of the upper cover transfer and installation mechanism 5 can use stepper motors, which have the characteristics of high control precision and stable operation. The clamping mechanism 56 can use a pneumatic gripper, which realizes clamping and releasing actions through a pneumatic system. The lifting drive mechanism 63 of the upper sealing ring assembly mechanism 6 can use an electric push rod, which can provide a stable lifting force. Of course, the above-mentioned drive methods can all be replaced by known similar mechanisms.

[0065] A filter assembly method includes the following steps:

[0066] Cup body input steps: The cup body 91 is input through the first input mechanism 31, and then the cup body 91 is transferred to the positioning groove 21 on the conveying mechanism 2 by the first transfer mechanism 41;

[0067] Lower sealing ring installation steps: The second input mechanism 32 inputs the lower sealing ring 92, and the second transfer mechanism 42 puts the lower sealing ring 92 onto the connecting screw 911 of the cup body 91;

[0068] Filter screen sleeve installation steps: The third input mechanism 33 inputs the filter screen sleeve 93, and the third transfer mechanism 43 puts the filter screen sleeve 93 onto the connecting screw 911 of the cup body 91;

[0069] Upper gasket installation steps: 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 screen sleeve 93;

[0070] Upper sealing ring assembly steps: The fifth input mechanism 35 inputs the upper sealing ring 95, and the fifth transfer mechanism 45 puts the upper sealing ring 95 onto the tapered sleeve 61;

[0071] Top cover installation steps: The sixth input mechanism 36 inputs the top cover 96. The top cover transfer and installation mechanism 5 transfers the top cover 96 to above the conical sleeve rod 61. The lifting drive mechanism 55 presses down so that the top cover 96 presses against the upper end of the conical sleeve rod 61. The lifting drive mechanism 63 drives the lifting ring 62 to rise, so that the upper sealing ring 95 is locked on the top cover 96. The top cover 96 is transferred to above the cup body 91 on the conveying mechanism 2. The lifting drive mechanism 55 presses down so that the top cover 96 presses against the connecting screw 911 of the cup body. The transmission drive mechanism 57 drives the clamping mechanism 56 to rotate the top cover 96 to connect with the connecting screw 911, thereby realizing the assembly.

[0072] When the second input mechanism 32 or the fourth input mechanism 34 delivers the lower sealing ring 92 or the upper gasket 94, intermittent vibration is added. When the lower sealing ring 92 or the upper gasket 94 is in the pickup position, the vibration stops.

[0073] This filter assembly method details each step of the filter assembly process, forming a complete and systematic assembly flow. By clearly defining the steps and operational requirements, it reduces uncertainties and human error during assembly, making the process more standardized and efficient. The steps are closely linked and logically clear, enabling automated production and quality control. Following this method allows for the rapid and accurate completion of filter assembly tasks, improving assembly efficiency and product quality while reducing production costs.

[0074] Intermittent vibration keeps the lower sealing ring 92 or the upper gasket 94 loose during transport, preventing components from sticking together due to prolonged stillness. By appropriately setting the vibration frequency, duration, and stop time, vibration can be stopped when the lower sealing ring 92 or the upper gasket 94 is in the pickup position, ensuring the component remains stable at the moment of pickup and reducing component positional shifts caused by vibration. This improves the accuracy and reliability of the first transfer mechanism 41, second transfer mechanism 42, third transfer mechanism 43, fourth transfer mechanism 44, and fifth transfer mechanism 45 in picking up components, ensuring smooth assembly processes, reducing production failures and defect rates caused by component picking problems, and improving production efficiency and product quality.

[0075] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
