Description

Technical Field

[0001] This invention relates to the field of filter element manufacturing technology, and in particular to an automated assembly system for filter element cores. Background Technology

[0002] Existing filter elements generally consist of an outer shell and an inner core housed inside the outer shell. Some PCB filter elements have a more complex inner core structure, such as... Figure 1 This refers to the inner core structure of a PCB composite filter element in the prior art, which includes a rear upper end cover 11, a first filter cartridge 12, a rear lower end cover 13, an outer cylinder 14, a cover plate 15, a second filter cartridge 16, an end cover 17, a separator tube 18, a central tube 19, and multiple sealing rings.

[0056] The present invention is provided below with reference to the accompanying drawings to aid in a full understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0057] In the description of this invention, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0058] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0059] Embodiments of the present invention provide an automated assembly system for filter cartridge cores, such as... Figure 1 , Figure 2 and Figure 3As shown, the device includes a product conveying device 100 and, arranged sequentially along the conveying direction of the product conveying device 100, a rear upper end cap assembly device 200, a rear lower end cap assembly device 300, an outer cylinder assembly device 400, a cover plate assembly device 500, a first airtightness testing device 601, a second filter cartridge assembly device 700, an end cap assembly device 800, a separator tube assembly device 900, a central tube assembly device 1000, and a second airtightness testing device 602. The product conveying device 200 includes a product placement seat 110, which receives products processed by each device and sequentially conveys the products to the next device along the conveying direction, so that the inner core is gradually assembled and formed along the conveying direction. The rear upper end cap assembly device 200 is used to assemble and fix the rear upper end cap 11 to one end of the first filter cartridge 12. The rear lower end cap assembly device 300 is used to assemble and fix the rear lower end cap 13 to the other end of the first filter cartridge 12. The outer cylinder assembly device 400 is used to assemble the first filter cartridge 12, which has the rear upper end cap 11 and the rear lower end cap 13 assembled, into the outer cylinder 14. The cover plate assembly device 500 is used to seal and fix the cover plate 15 at the opening of the outer cylinder 14. At this time, the product including the rear upper end cap 11, the first filter cartridge 12, the rear lower end cap 13, the outer cylinder 14, and the cover plate 15 is the inner core semi-finished product 10. The first airtightness testing device 6 01 is used to perform airtightness testing on the inner core semi-finished product 10 to determine whether the airtightness of the inner core semi-finished product 10 is qualified; the second filter cartridge assembly device 700 is used to assemble and fix the second filter cartridge 16 on the inner core semi-finished product 10; the end cap assembly device 800 is used to assemble and fix the end cap 17 at the end of the second filter cartridge 16; the separator tube assembly device 900 is used to assemble the separator tube 18 into the second filter cartridge 16; the center tube assembly device 1000 is used to assemble the center tube 19 into the separator tube 18 to make the inner core finished product; and the second airtightness testing device 602 is used to perform airtightness testing on the inner core finished product to determine whether the airtightness of the inner core finished product is qualified.

[0060] In this embodiment, the coordinated operation of the product conveying equipment 100, the rear upper end cap assembly device 200, the rear lower end cap assembly device 300, the outer cylinder assembly device 400, the cover plate assembly device 500, the second filter cartridge assembly device 700, the end cap assembly device 800, the separator tube assembly device 900, and the center tube assembly device 1000 enables automated assembly of the inner core, significantly reducing labor costs and effectively improving production efficiency. Simultaneously, the first airtightness testing device 601 and the second airtightness testing device 602 respectively perform airtightness testing on the inner core semi-finished product 10 and the inner core finished product to determine product quality, thereby improving the product yield.

[0061] It should be noted that the product conveying equipment 100, the rear upper end cover assembly device 200, the rear lower end cover assembly device 300, the outer cylinder assembly device 400, the cover plate assembly device 500, the first airtightness testing device 601, the second filter cartridge assembly device 700, the end cover assembly device 800, the partition tube assembly device 900, the central tube assembly device 1000, and the second airtightness testing device 602 can all be connected to the control module. The control module issues control commands to each device according to the preset control program to control the above-mentioned devices to coordinate with each other, thereby realizing the automated assembly of the inner core.

[0062] The automated assembly system for the filter element core of this invention involves the handling and assembly of various materials, and accordingly utilizes the feeding assembly, feeding device, handling assembly, handling device, assembly assembly, and assembly device described below. These components or devices may include a lateral movement assembly, a longitudinal movement assembly, and a vertical movement assembly. The lateral movement assembly can move the target object laterally, the longitudinal movement assembly can move the target object longitudinally, and the vertical movement assembly can move the object vertically. The lateral movement assembly, longitudinal movement assembly, and vertical movement assembly can be used individually to move the target object in one direction, or any two or three can be combined to move the target object in multiple directions. The lateral movement assembly may include a lateral fixed base, a lateral guide rail disposed on the lateral fixed base, a lateral slider slidably engaged with the lateral guide rail, and a lateral driver connected to the lateral slider. The target object can be fixed on the lateral slider, and the lateral driver drives the lateral slider to slide along the lateral guide rail, thereby moving the target object laterally. Similarly, the longitudinal movement component may include a longitudinal fixed base, a longitudinal guide rail mounted on the longitudinal fixed base, a longitudinal slider slidably engaged with the longitudinal guide rail, and a longitudinal driver connected to the longitudinal slider. The target object can be fixed on the longitudinal slider, and the longitudinal driver drives the longitudinal slider to slide along the longitudinal guide rail, thereby moving the target object longitudinally. The vertical movement component may include a vertical fixed base, a vertical guide rail mounted on the vertical fixed base, a vertical slider slidably engaged with the vertical guide rail, and a vertical driver connected to the vertical slider. The target object can be fixed on the vertical slider, and the vertical driver drives the vertical slider to slide along the vertical guide rail, thereby moving the target object vertically. The transverse driver, longitudinal driver, and vertical driver include, but are not limited to, motors and cylinders.

[0063] To facilitate the movement of items using the aforementioned moving component, a clamp is also provided on the component. When the moving component moves the clamp near the target object, the clamp briefly secures the object to itself, allowing the moving component to move the clamp and consequently move the target object. When the moving component moves the clamp near the target location, the clamp releases the object, allowing it to fall into the target position. The clamp can be a fixed gripper, securing the target object through external or internal clamping; alternatively, it can be a magnetic adsorption device, using magnetic attraction to attract the target object; or it can be a vacuum adsorption device, using negative pressure to attract the target object. Of course, other forms of clamps can be used depending on the specific needs.

[0064] Simultaneously, this invention also relates to the supply of materials to ensure continuous production on the production line. Accordingly, the supply components, supply devices, or supply mechanisms described below are used. These supply components, devices, or mechanisms store large quantities of materials and can be regularly output to transport or assembly components for further processing and assembly. For example... Figure 8 As shown, the supply component, supply device, or supply mechanism may include a vibratory feeder and a conveyor track connected to the vibratory feeder. The vibratory feeder stores materials and conveys them to the conveyor track by vibration. The conveyor track can transport the materials one by one to the target workstation for the handling component or assembly component to remove the materials. For example... Figure 4 As shown, the supply component, supply device, or supply mechanism may include a tray, a tray longitudinal moving mechanism, and a tray lifting mechanism. Materials can be neatly arranged in the tray. The tray longitudinal moving mechanism can drive the tray to move longitudinally, specifically from a loading position to a unloading position. The tray lifting mechanism can lift or lower the tray. During operation, the tray lifting mechanism lifts the tray loaded with materials from below the loading position to the loading position. Once all the materials on the tray have been removed, the tray longitudinal moving mechanism moves the empty tray to the unloading position. The tray lifting mechanism receives the empty tray at the unloading position and then removes it.

[0065] In some embodiments, such as Figure 2 and Figure 3As shown, the product conveying equipment 100 may include one or more product conveying mechanisms 120. A product placement seat 110 is connected to the product conveying mechanism 120, and the product conveying mechanism 120 drives the product placement seat 110 to move along the conveying direction. A product placement slot 111 may be provided on the product placement seat 110, where both the product to be processed and the processed product are placed to ensure product stability during conveying. Two product placement slots 111 may be provided, one for placing the product to be processed and the other for placing the processed product, facilitating product transfer. The product conveying mechanism 120 may include a conveyor belt, a linear track, or other mechanisms capable of transporting products.

[0066] Considering that some processed products need to be flipped during subsequent assembly and processing, the product conveying equipment 100 may include a flipping component. When the product conveying mechanism 120 conveys the product to the flipping component, the flipping component flips the product over for subsequent assembly and processing.

[0067] In some embodiments, such as Figure 4 and Figure 5 As shown, the rear top cover assembly device includes a first turntable 201 and a rear top cover feeding assembly 210, a first glue application assembly 220, a first filter cartridge feeding assembly 230, a first pressing assembly 240, and a first unloading assembly 250 arranged sequentially along the rotation direction of the first turntable 201. Multiple first placement seats 202 are arranged circumferentially on the first turntable 201, and products are placed on the first placement seats 202. The first turntable 201 is connected to a corresponding turntable drive mechanism, which drives the first turntable 201 to rotate, thereby moving the products on the first placement seats 202 sequentially to the rear top cover feeding assembly 210, the first glue application assembly 220, the first filter cartridge feeding assembly 230, the first pressing assembly 240, and the first unloading assembly 250 for processing and assembly of the products. The rear upper cover feeding assembly 210 is used to place the rear upper cover 11 on the first placement seat 202. The first adhesive application assembly 220 is used to apply adhesive to the inner side of the rear upper cover 11 (the side closest to the first filter cartridge 12). The first filter cartridge feeding assembly 230 is used to place the first filter cartridge 12 onto the inner side of the adhesive-coated rear upper cover 11, thus bonding the rear upper cover 11 and the first filter cartridge 12 together. The first pressing assembly 240 is used to press the first filter cartridge 12 downwards, ensuring full contact between the first filter cartridge 12 and the adhesive, allowing the first filter cartridge 12 to adhere tightly to the rear upper cover 11, improving the bonding strength. The first unloading assembly 250 is used to move the bonded first filter cartridge 12 and rear upper cover 11 to the product placement seat. Thus, the rear upper cover assembly device completes the processing of the product. The product conveying equipment then conveys the product processed by the upper cover assembly device to the next device.

[0068] Furthermore, the rear upper cover assembly device also includes a rear upper cover supply assembly 260, which docks with the rear upper cover feeding assembly 210 to deliver the rear upper cover 11 to the rear upper cover feeding assembly 210. The rear upper cover feeding assembly 210 picks up the upper cover 11 delivered by the rear upper cover supply assembly 260 and places it on the first placement seat 202. The rear upper cover supply assembly 260 may include a rear upper cover vibratory feeder and a linear vibration guide rail connected to the rear upper cover vibratory feeder.

[0069] The rear upper cover assembly device also includes a first filter cartridge supply assembly 270, which outputs a first filter cartridge 12. A first filter cartridge feeding assembly 230 picks up the first filter cartridge 12 output by the first filter cartridge supply assembly 270 and then places the first filter cartridge 12 onto the rear upper cover 11. The first filter cartridge supply assembly 270 may include a tray containing a plurality of neatly arranged first filter cartridges 12 to facilitate accurate picking up of the first filter cartridge 12 by the first filter cartridge feeding assembly 230.

[0070] Furthermore, the rear upper cover assembly device also includes a placement seat rotation assembly 280, which can be located below the first adhesive application assembly 220. The first placement seat 202 is rotatably connected to the first turntable 202. When the first placement seat 202 moves with the rear upper cover 11 to below the first adhesive application assembly 220, the placement seat rotation assembly 280 can drive the first placement seat 202 to rotate, which in turn drives the rear upper cover 11 to rotate. The first adhesive application assembly 220 can then apply adhesive in a ring shape on the rear upper cover 11, increasing the contact area of ​​the adhesive and improving the adhesion.

[0071] Furthermore, a rotating seat 203 is fixed to the bottom of the first placement seat 202, penetrating the first turntable 202. The rotating seat 203 is rotatably connected to the first turntable 202, and a rotating seat slot 204 is provided at the bottom of the rotating seat 203. The placement seat rotation assembly 280 includes a rotation lifting mechanism 281, a rotation drive mechanism 282 connected to the rotation lifting mechanism 281, and a rotation drive rod 283 connected to the rotation drive mechanism 282. The rotation lifting mechanism 281 can drive the rotation drive mechanism 282 to move vertically, and the rotation drive mechanism 282 can drive the rotation drive rod 283 to rotate. When the rotating seat 203 rotates to directly above the placement seat rotation assembly 280, the rotation lifting mechanism 281 drives the rotation drive rod 283 to move upward to insert into the rotating seat slot 204, and the rotation drive mechanism 282 drives the rotation drive rod 283 to rotate, thereby driving the first placement seat 202 to rotate. After the adhesive application is completed, the rotating lifting mechanism 281 drives the rotating drive rod 283 downward, and the rotating drive rod 283 moves out of the rotating seat slot 204 so as not to affect the movement of the first placement seat 202 to the next component. In the various devices mentioned below that involve the adhesive application component, the placement seat in the device can be rotatably connected to the turntable, and the corresponding device can include a placement seat rotating assembly similar to that in this embodiment, which is arranged below the adhesive application component.

[0072] In some embodiments, such as Figure 1 , Figure 6 and Figure 7As shown, the rear lower end cap assembly device includes a second turntable 301 and a first loading / unloading assembly 310, a rear lower end cap loading assembly 320, a first sealing ring assembly 330, a second adhesive application assembly 340, a first flipping assembly 340, and a second pressing assembly 360 arranged sequentially along the rotation direction of the second turntable 301. Multiple sets of placement seats are arranged circumferentially on the second turntable 301. Each set of placement seats includes two second placement seats 302, with the two second placement seats 302 in the same set close to each other. The first loading / unloading assembly 310 is used to place the first filter cartridge and the rear upper end cap, which are processed and glued together by the rear upper end cap assembly device, into one of the second placement seats 302. The rear lower end cap loading assembly 320 is used to place the rear lower end cap 13 into the other second placement seat 302 in the same set. This ensures that the loading of the first loading / unloading assembly 310 and the rear lower end cap loading assembly 320 will not interfere with each other, guaranteeing efficient and stable operation of the turntable. The first sealing ring assembly 330 is used to assemble the first sealing ring 21 onto the rear lower end cover to improve sealing and prevent leakage. The second adhesive application assembly 340 is used to apply adhesive to the inner side of the rear lower end cover 13 (i.e., the side closest to the first filter cartridge). Since the rear upper end cover is located below the first filter cartridge when assembling the rear upper end cover and the first filter cartridge, the first filter cartridge needs to be flipped over. The first flipping assembly 350 is used to flip the first filter cartridge over and place it on the inner side of the rear lower end cover 13, so that the first filter cartridge is stuck together with the rear lower end cover 13. The second pressing assembly 360 is used to press the rear upper end cover 13 downward to make the first filter cartridge and the rear lower end cover 13 stick tightly together. The first loading and unloading assembly 310 is used to move the first filter cartridge, with the rear upper end cover and the rear lower end cover 13 assembled, onto the product placement seat. The product conveying equipment then transports the first filter cartridge, which has been assembled with the rear upper end cover and the rear lower end cover 13, to the next device.

[0073] In this embodiment, the rear lower end cap assembly device further includes a rear lower end cap supply component 370, which conveys the rear lower end cap 13 outward. A rear lower end cap feeding component 320 picks up the rear lower end cap 13 conveyed by the rear lower end cap supply component 370 and then feeds it. The rear lower end cap assembly device also includes a first sealing ring supply component 380, which outputs a first sealing ring. A first sealing ring assembly component 330 picks up the first sealing ring output by the first sealing ring supply component 380 and then assembles it.

[0074] The first flip assembly 350 includes a flip lifting mechanism, a flip rotation mechanism connected to the flip lifting mechanism, and a flip clamp connected to the flip lifting mechanism. The flip clamp is used to hold or release the first filter cartridge. When the first filter cartridge moves to the flip clamp, the flip clamp holds the first filter cartridge. The flip lifting mechanism drives the flip clamp to move upward, and the first filter cartridge leaves the second placement seat 302. The flip lifting mechanism drives the flip clamp to rotate, which in turn drives the first filter cartridge to rotate, thereby flipping the first filter cartridge over. The flip lifting mechanism then drives the flip clamp to move downward, so that the first filter cartridge is placed on the inner side of the rear lower end cover 13.

[0075] The first sealing ring assembly 330 includes a first sealing ring transport mechanism 331, a transport fixing seat 332, a first sealing ring clamping assembly, a first sealing ring unloading assembly, and an oil tank 335. The oil tank 335 is filled with oil. After the sealing ring is dipped in the oil, it can fit tightly against the surface of the installation position, thereby improving the sealing performance. The first sealing ring clamping assembly and the first sealing ring unloading assembly are both fixed on the transport fixing seat 332 for linkage with the transport fixing seat 332. The transport fixing seat 332 is connected to the first sealing ring transport mechanism 331, which can drive the transport fixing seat 332 to move laterally and vertically. The first sealing ring transport mechanism 331 first moves the first sealing ring clamping assembly closer to the sealing ring, then the first sealing ring clamping assembly clamps the first sealing ring. The first sealing ring transport mechanism 331 moves the first sealing ring to absorb oil from the oil tank 335, and then moves the first sealing ring closer to the rear lower end cover where the first sealing ring is to be installed, so that the first sealing ring aligns with the rear lower end cover. Afterwards, the first sealing ring unloading assembly can move vertically relative to the first sealing ring clamping assembly to detach the first sealing ring from the first sealing ring unloading assembly, and then assemble it onto the rear lower end cover. Since the first sealing ring needs to be fitted onto the rear lower end cover, the first sealing ring clamping assembly needs to deform the first sealing ring radially. The first sealing ring has resilience, so it is not easy to fall off the first sealing ring clamping assembly. In this embodiment, by moving the sealing ring axially through the first sealing ring unloading assembly, the sealing ring can be detached from the first sealing ring clamping assembly, thereby completing the assembly.

[0076] The first sealing ring clamping assembly may include multiple first sealing ring inner support clamping blocks 333 and an inner support clamping block driving mechanism that drives the first sealing ring inner support clamping blocks 333 to expand or contract. When the first sealing ring inner support clamping blocks 333 expand, they can clamp the sealing ring inward; when the first sealing ring inner support clamping blocks 333 contract, they can release the clamped sealing ring. The first sealing ring unloading assembly includes a first sealing ring unloading plate 334 and a sealing ring unloading plate driving mechanism that drives the first sealing ring unloading plate 334 to move axially along the sealing ring. The first sealing ring unloading plate 334 is sleeved on the outside of the first sealing ring inner support clamping blocks 333. When the sealing ring is sleeved on the outside of the first sealing ring inner support clamping blocks 333, the sealing ring unloading plate driving mechanism drives the first sealing ring unloading plate 334 to move axially along the sealing ring, thereby detaching the sealing ring from the first sealing ring inner support clamping blocks 333.

[0077] It should be noted that the other sealing ring assembly components described below can all be assembled using similar structures and principles.

[0078] In some embodiments, such as Figure 1 and Figure 8 As shown, the outer cylinder assembly device includes a third turntable 401 and an outer cylinder feeding assembly 410, a second sealing ring assembly 420, and a second loading / unloading assembly 430 arranged sequentially along the rotation direction of the third turntable 401. Multiple third placement seats 402 are arranged circumferentially on the third turntable 401. When the third turntable 401 rotates, it can drive the third placement seats 402 to move sequentially to the outer cylinder feeding assembly 410, the second sealing ring assembly 420, and the second loading / unloading assembly 430 for assembly processing. The outer cylinder feeding assembly 410 is used to place the outer cylinder 14 on the third placement seat 402. The second sealing ring assembly assembly 420 is used to assemble the second sealing ring 22 onto the outer cylinder 14. The second loading and unloading assembly 430 is used to assemble the first filter cartridge with the rear upper end cover and the rear lower end cover assembled on the product placement seat into the outer cylinder 14, and then move the assembled outer cylinder back onto the product placement seat. The product conveying equipment then conveys the processed product to the next device.

[0079] The outer cylinder assembly device also includes an outer cylinder supply component 440 and a second sealing ring supply component 450. The outer cylinder supply component 440 supplies the outer cylinder to the outer cylinder feeding component 410, and the second sealing ring supply component 450 supplies the second sealing ring to the second sealing ring assembly component 420.

[0080] In some embodiments, such as Figure 9As shown, the cover plate assembly device includes an intermediate conveying assembly 510, a first transfer assembly 520 located at the starting end of the intermediate conveying assembly 510, a second transfer assembly 530 located at the tail end of the intermediate conveying assembly 510, and cover plate loading assembly 540, cover plate spin-melting assembly 550, and marking assembly 560 arranged sequentially along the conveying direction of the intermediate conveying assembly 510. The intermediate conveying assembly 510 includes a plurality of intermediate placement seats 511, which can move from the starting end to the tail end of the intermediate conveying assembly 510 to sequentially move products to the first transfer assembly 520, cover plate loading assembly 540, cover plate spin-melting assembly 550, marking assembly 560, and second transfer assembly 530 for assembly processing. The first transfer assembly 520 is used to move the outer cylinder with the first filter cartridge assembled on it from the product placement seat to the intermediate placement seat 511, so that the intermediate conveying assembly 510 can move the outer cylinder along the conveying direction. The cover plate loading assembly 540 is used to assemble the cover plate to the opening of the outer cylinder, so as to wrap the first filter cartridge with the rear upper end cover and the rear lower end cover in the outer cylinder. The cover plate spin welding assembly 550 is used to spin weld and fix the cover plate to the outer cylinder, so that the cover plate is fixedly connected to the outer cylinder, thereby producing the inner core semi-finished product. The marking assembly 560 is used to perform laser marking on the surface of the inner core semi-finished product to print out the relevant information of the inner core.

[0081] The cover plate assembly device may further include a cover plate supply assembly 570, which is used to feed the cover plate to the cover plate loading assembly 540. Both the first transfer assembly 520 and the cover plate loading assembly 540 can be fixed on the same bracket to reduce the space occupied during installation.

[0082] In some embodiments, such as Figure 10-13 As shown, both the first airtightness testing device 601 and the second airtightness testing device 602 include a testing platform 610 and a product handling device 620. The testing platform 610 is equipped with several airtightness testing components 630. The first airtightness testing device 601 is used to perform airtightness testing on the semi-finished inner core, and the second airtightness testing device 602 is used to perform airtightness testing on the finished inner core. During airtightness testing, the product handling device 620 first places the product to be tested 30 on the airtightness testing component 630 and aligns the product to be tested 30 with the airtightness testing component 630. The airtightness testing component 630 performs airtightness testing on the aligned product to be tested 30. After the product to be tested 30 completes the test, the product handling device 620 removes the product that has completed the airtightness test from the airtightness testing component 630.

[0083] In some embodiments, the airtightness testing component 630 includes a testing plate 631 and a testing air path integration 632. The product to be tested 30 has several fluid inlets and fluid outlets, such as a water inlet, a pure water outlet, a clean water outlet, and a wastewater outlet. Fluid enters the product to be tested 30 through the fluid inlets and flows out of the product to be tested 30 through the fluid outlets. The top surface of the testing plate 631 is provided with a plurality of air holes 633 respectively adapted to the fluid inlets and fluid outlets of the product to be tested 30. Specifically, the number, position, and size of the air holes 633 are adapted to the number, position, and size of the corresponding fluid inlets and fluid outlets. The testing air path integration 632 is connected to the testing plate 631 and communicates with the air holes 633. During airtightness testing, the product handling device 620 connects the fluid inlet and fluid outlet of the product under test 30 to the corresponding air vents 633. The detection gas path integration 632 introduces gas into the product under test 30 through the air vents 633, and then determines the airtightness of the product under test 30 by detecting the gas pressure or gas flow rate. Since the detection gas path integration 632 is existing technology, its specific structure and principle will not be described in this embodiment. In this embodiment, the detection gas path integration 632 can be fixed below the detection plate 631 to avoid exposure and occupying space on the detection stage 610, and to facilitate communication between the detection gas path integration 632 and the air vents 633.

[0084] Furthermore, the top surface of the testing plate 631 is provided with a positioning groove 634, and air holes 633 are provided on the bottom wall of the positioning groove 634. During the airtightness test, the product handling device 620 inserts the product to be tested 30 into the positioning groove 634. On the one hand, this positions the product to be tested 30, so that the fluid inlet and fluid outlet of the product to be tested 30 can accurately align with the corresponding air holes 633. On the other hand, the side wall of the positioning groove 634 can limit the product to be tested 30, making it less prone to shaking and able to be stably placed on the testing plate 631.

[0085] In some embodiments, the product handling device 620 includes a multi-axis robotic arm 621 and a product gripper 622 connected to the multi-axis robotic arm 621. The product gripper 622 can grip or release the product 30 to be inspected. The multi-axis robotic arm 621 can drive the product gripper 622 to move in multiple dimensions, thereby driving the product 30 to be inspected held by the product gripper 622 to move in multiple dimensions, and thus transporting the product 30 to be inspected. Because the multi-axis robotic arm 621 has more flexible and versatile movements, it can adapt to different working environments.

[0086] Furthermore, the product clamp 622 includes two grippers 623 that can move closer to or further away from each other. The two grippers 623 are connected to corresponding drive mechanisms. The drive mechanisms can drive the two grippers 623 closer together to clamp the product 30 to be inspected, and can also drive the two grippers 623 further apart to release the product 30 to be inspected. The opposing surfaces (the sides that move closer together) of the two grippers 623 are each provided with an inner groove 624 that is adapted to the product 30 to be inspected. When clamping the product 30 to be inspected, a portion of the product 30 is embedded in the inner groove 624, thus making the clamping of the product 30 to be inspected more stable.

[0087] In this embodiment, multiple airtightness testing components 630 can be neatly arranged on the testing table 610, and multiple product fixtures 622 can also be neatly arranged accordingly. In this way, multiple products 30 to be inspected can be transported at one time, and airtightness testing can be performed on multiple products 30 to be inspected at the same time, so as to increase the number of tests and further improve production efficiency.

[0088] In some embodiments, the testing station 610 is further provided with a clamping component 640 located above the airtightness testing component 630. After the product handling device 620 places the product to be tested 30 on the airtightness testing component 630, the clamping component 640 can press the product to be tested 30 downwards, so that the product to be tested 30 is tightly pressed on the airtightness testing component 630, to prevent air leakage at the docking positions of the fluid inlet and fluid outlet of the product to be tested and the corresponding air holes 633. After the airtightness test of the product to be tested 30 is completed, the clamping component 640 no longer presses the product, so that the product handling device 620 can remove the product from the airtightness testing component 630. Therefore, this embodiment can avoid false detections caused by air leakage and effectively improve the accuracy of the test results.

[0089] Furthermore, the clamping assembly 640 includes a clamping bracket 641, a clamping actuator 642, and a clamping plate 643. The clamping bracket 641 is fixed on the testing table 610, and the clamping actuator 642 is fixed on the clamping bracket 641 to raise the clamping actuator 642 to a certain height, positioning it above the airtightness testing assembly 630. The clamping plate 643 is connected to the clamping actuator 642, which drives the clamping plate 643 to move vertically towards or away from the product 30 to be inspected on the airtightness testing assembly 630, thereby clamping or releasing the product 30 to be inspected. The clamping actuator 642 can be a cylinder.

[0090] Furthermore, a clamping guide rod 644 is provided on the clamping plate 643, and a clamping guide cylinder 645 arranged vertically is provided on the clamping bracket 641. The clamping guide rod 644 passes through the clamping guide cylinder 645 and can move vertically within the clamping guide cylinder 645. The clamping guide cylinder 645 guides the clamping guide rod 644, so that the clamping plate 643 moves stably vertically, ensuring that the clamping plate 643 can be stably pressed onto the product 30 to be inspected.

[0091] In some embodiments, the automatic filter element airtightness testing equipment further includes a qualified product unloading assembly 651 and a non-qualified product unloading assembly 652. The product handling device 620 places products with qualified test results into the qualified product unloading assembly 651. The qualified product unloading assembly 651 can dock with a product conveying device so that products with qualified test results can continue to undergo subsequent assembly and processing. For products with non-qualified test results, the product handling device 620 places them into the non-qualified product unloading assembly 652, thus classifying qualified and non-qualified products and avoiding confusion. The non-qualified product unloading assembly 652 may include an inclined unloading plate and a receiving box docked with the unloading plate.

[0092] In some embodiments, such as Figure 14 and 15 As shown, the second filter cartridge assembly device 700 includes a fourth turntable 701 and a second feeding assembly 710, a third gluing assembly 720, a second filter cartridge feeding assembly 730, a third pressing assembly 740, and a second unloading assembly 750 arranged sequentially along the rotation direction of the fourth turntable 701. Multiple fourth placement seats 702 are arranged circumferentially on the fourth turntable 701. When the fourth turntable 701 rotates, the products on the fourth placement seats 702 are moved sequentially to the second feeding assembly 710, the third gluing assembly 720, the second filter cartridge feeding assembly 730, the third pressing assembly 740, and the second unloading assembly 750. The second feeding assembly 710 moves the inner core semi-finished product on the product placement seat to the fourth placement seat 702. The third adhesive application assembly 720 applies adhesive to the top surface of the inner core semi-finished product. The second filter cartridge feeding assembly 730 places the second filter cartridge on the top surface of the adhesive-coated inner core semi-finished product to bond them together. The third pressing assembly 740 presses the second filter cartridge downwards to increase the contact area between the second filter cartridge and the adhesive, ensuring a tight bond between the second filter cartridge and the inner core semi-finished product and improving the adhesion strength. The second unloading assembly 750 moves the bonded second filter cartridge and inner core semi-finished product to the product placement seat. The product conveying equipment then conveys the bonded second filter cartridge and inner core semi-finished product to the next device.

[0093] The second filter cartridge assembly device also includes a second filter cartridge supply assembly 760, which supplies the second filter cartridge to the second filter cartridge feeding assembly 730 for clamping and assembly. The second filter cartridge assembly device also includes a positioning clamp 770, which can be located on one side of the second filter cartridge assembly station. When the inner core semi-finished product on the product placement seat moves to the second filter cartridge assembly station, the positioning clamp 770 holds the inner core semi-finished product, keeping it stable to ensure that the second filter cartridge feeding assembly 730 accurately places the second filter cartridge on the top surface of the inner core semi-finished product.

[0094] In some embodiments, such as Figure 1 , Figure 16 and 17As shown, the end cap assembly device includes an end cap conveying assembly 810, a third sealing ring assembly 820, a fifth turntable 801, and a third loading / unloading assembly 830, an end cap loading assembly 840, a fourth gluing assembly 850, a second flipping assembly 860, and a fourth pressing assembly 870 arranged sequentially along the rotation direction of the fifth turntable 801. Multiple sets of placement seats are arranged circumferentially on the fifth turntable 801, each set including two fifth placement seats 802, with the two fifth placement seats 802 in the same set close to each other. The third sealing ring assembly 820 and the end cap loading assembly 840 are arranged sequentially along the conveying direction of the end cap conveying assembly 810, allowing the end cap conveying assembly 810 to sequentially convey the end caps to the third sealing ring assembly 820 and the end cap loading assembly 840. The third sealing ring assembly 820 is used to assemble the third sealing ring 23 onto the end cap 17. The third loading and unloading assembly 830 is used to place the glued-together second filter cartridge 16 and inner core semi-finished product 10 into one of the fifth placement seats 802. The end cap loading assembly 840 is used to place the end cap with the third sealing ring assembled into another fifth placement seat 802 in the same group. In this way, the loading of the third loading and unloading assembly 830 and the loading of the end cap loading assembly 840 will not interfere with each other, ensuring efficient and stable operation of the turntable. The fourth adhesive application assembly 850 is used to apply adhesive to the inner side of the end cap (the side closest to the second filter cartridge). Because the second filter cartridge 16 is positioned above the inner core semi-finished product 10 during the assembly of the second filter cartridge assembly device, and the assembly of the end cap requires connecting the top of the second filter cartridge 16 to the end cap, the assembled second filter cartridge 16 and inner core semi-finished product 10 need to be flipped over during end cap assembly, with the second filter cartridge 16 facing downwards. The second flip assembly component 860 is used to flip the second filter cartridge over and place it on the inner side of the end cap, where the second filter cartridge is adhered to the end cap. The end cap and inner core semi-finished product are located at opposite ends of the second filter cartridge. The fourth pressing component 870 is used to press the inner core semi-finished product downwards to ensure the second filter cartridge and end cap are firmly bonded together, improving the adhesion. The third loading and unloading component 830 is used to move the second filter cartridge with the assembled inner core semi-finished product and end cap to the product placement seat. The product conveying equipment then conveys the processed product to the next device.

[0095] like Figure 1 As shown, the third sealing ring 23 is assembled on the top surface of the end cap 17, while the second filter cartridge 16 is glued to the bottom surface of the end cap 17. Therefore, the end cap 17 needs to be flipped over. Figure 16 and 17As shown, the end cap conveying assembly 810 includes an end cap conveying mechanism, an end cap rotating mechanism 812 connected to the end cap conveying mechanism, and an end cap clamp 811 connected to the end cap rotating mechanism 812. The end cap rotating mechanism 812 drives the end cap clamp 811 to rotate, and the end cap conveying mechanism drives the end cap rotating mechanism to move along the conveying direction of the end cap. When the end cap is moved to the third sealing ring assembly 820, the top surface of the end cap faces upward for assembly of the third sealing ring. After the assembly of the third sealing ring is completed, the end cap rotating mechanism 812 drives the end cap clamp 811 to rotate, correspondingly causing the end cap to flip up to the bottom surface facing upward for subsequent assembly onto the second filter cartridge.

[0096] The third sealing ring assembly 820 includes a third sealing ring clamp 821, which can clamp the third sealing ring by means of internal support clamping. For a detailed description of the third sealing ring assembly 820, please refer to the first sealing ring assembly assembly in the above embodiment.

[0097] The end cap assembly device also includes an end cap supply assembly 880 and a third sealing ring supply assembly 890, which supply the end cap and the third sealing ring, respectively.

[0098] In some embodiments, such as Figure 18-24 As shown, the central tube assembly device includes a central tube supply device 3100, a central tube conveying device 3200, two fifth sealing ring assembly devices 3300, and a central tube assembly device 3400. The central tube supply device 3100 supplies the central tube 19 and conveys it to the central tube conveying device 3200, which in turn conveys it to the central tube assembly device 3400. The two fifth sealing ring assembly devices 3300 are located on opposite sides of the conveying path of the central tube 19 on the central tube conveying device 3200, and are used to assemble the fifth sealing rings onto both ends of the central tube 19. This allows the assembly of the fifth sealing rings to be completed during the conveying of the central tube 19. The central tube assembly device 3400 receives the central tube 19 with the fifth sealing rings assembled from the central tube conveying device 3200 and then inserts the central tube 19 with the fifth sealing rings assembled into the second filter cartridge, thereby completing the assembly of the central tube 19.

[0099] In some embodiments, the central tube supply device includes a central tube tray 3110, a central tube tray moving assembly 3120, and a central tube conveying assembly 3130. The central tube tray 3110 is used to vertically place multiple central tubes 19. Specifically, the central tube tray 3110 is provided with multiple insertion holes, and the central tubes 19 are vertically inserted into the insertion holes to await clamping by the central tube conveying assembly 3130. The insertion holes can be evenly and regularly distributed, for example, in a dot matrix pattern, to facilitate smooth and orderly clamping of each central tube 19 by the central tube conveying assembly 3130. The central tube tray moving assembly 3120 is used to move the central tube tray 3110 to change its position, allowing the central tube conveying assembly 3130 to clamp central tubes 19 at different positions on the central tube tray 3110. The central tube conveying assembly 3130 is used to clamp the central tubes 19 on the central tube tray 3110 and place the central tubes 19 horizontally on the central tube conveying device 3200.

[0100] In this embodiment, the central tube 19 is inserted vertically into the central tube tray 3110. Compared to horizontal placement, this prevents the central tube 19 from rolling and allows it to maintain its position on the tray 3110, ensuring that the central tube transport assembly 3130 can smoothly pick up the central tube 19. Simultaneously, the size of the central tube tray 3110 can be reduced, increasing the number of central tubes 19 that can be loaded onto it. The central tube transport assembly 3130 places the central tube 19 horizontally on the central tube conveying device 3200. Under the transport of the central tube conveying device 3200, the central tube 19 moves horizontally, allowing the fifth sealing ring assembly devices 3300 on both sides to contact both ends of the central tube 19, thereby assembling the fifth sealing rings onto both ends of the central tube 19. This facilitates the arrangement of the fifth sealing ring assembly devices 3300.

[0101] Furthermore, the central tube tray moving assembly 3120 may include a tray longitudinal moving mechanism 3121, a tray clamping mechanism 3122, and a tray lifting mechanism 3123. The tray clamping mechanism 3122 is connected to the tray longitudinal moving mechanism 3121 and is used to clamp the central tube tray 3110 from both ends. The tray longitudinal moving mechanism 3121 can drive the tray clamping mechanism 3122 to move longitudinally, specifically from the loading position to the unloading position. The tray lifting mechanism 3123 is used to lift or lower the central tube tray 3110. During operation, the tray lifting mechanism 3123 lifts the tray 3110 containing the central tubes 19 from below the loading position to the loading position. The tray clamping mechanism 3122 then clamps the tray 3110. The tray longitudinal moving mechanism 3121 moves the tray clamping mechanism 3122. After all the central tubes 19 on the tray 3110 have been removed, the tray longitudinal moving mechanism 3121 moves the empty tray 3110 to the unloading position. The tray lifting mechanism 3123 receives the empty tray 3110 at the unloading position and then removes it. This ensures a continuous supply of central tubes 19. Alternatively, a tray trolley 3140 can be configured, carrying the trays 3110. The operator can push the tray trolley 3140 closer to the loading position and stack the trays 3110 below the loading position for the tray lifting mechanism 3123 to remove.

[0102] Furthermore, the central tube transport assembly 3130 includes a central tube lateral movement mechanism 3131, a central tube vertical movement mechanism 3132 connected to the central tube lateral movement mechanism 3131, a central tube rotation mechanism 3133 connected to the central tube vertical movement mechanism 3132, and a first central tube clamp 3134 connected to the central tube rotation mechanism 3133. The central tube lateral movement mechanism 3131 is used to drive the central tube vertical movement mechanism 3132 to move laterally, the central tube vertical movement mechanism 3132 is used to drive the central tube rotation mechanism 3133 to move vertically, and the first central tube clamp 3134 is used to clamp or release the central tube 19. Since the central tube lateral moving mechanism 3131, the central tube vertical moving mechanism 3132, the central tube rotating mechanism 3133, and the first central tube clamp 3134 are sequentially connected, when the central tube lateral moving mechanism 3131 and the central tube vertical moving mechanism 3132 are activated, they can correspondingly drive the central tube 19 held by the first central tube clamp 3134 to move laterally and vertically. The central tube rotating mechanism 3133 is used to drive the first central tube clamp 3134 to rotate so that the central tube 19 held by the first central tube clamp 3134 rotates from a vertical state to a horizontal state, so that the central tube 19 can be placed horizontally on the central tube conveying device 3200. In this embodiment, the central tube lateral moving mechanism 3131, the central tube vertical moving mechanism 3132, the central tube rotating mechanism 3133 and the first central tube clamp 3134 cooperate with each other so that the first central tube clamp 3134 can clamp the central tube 19 on the central tube tray 3110 and finally place the central tube 19 horizontally on the central tube conveying device 3200 to continuously convey the central tube 19 to the central tube conveying device 3200.

[0103] In some embodiments, the fifth sealing ring assembly device 3300 includes a fifth sealing ring supply assembly 3310, a sealing ring oil tank 3320, a fifth sealing ring transport assembly 3330, and a fifth sealing ring assembly 3340. The fifth sealing ring supply assembly 3310 supplies fifth sealing rings for continuous assembly. The fifth sealing ring transport assembly 3330 first places the fifth sealing ring supplied by the fifth sealing ring supply assembly 3310 into the sealing ring oil tank 3320 to absorb oil. After absorbing oil, the fifth sealing ring can fit more tightly against the central tube 19, thus ensuring a tight seal. The sealing ring transport assembly 3330 then transports the oil-soaked fifth sealing ring to the fifth sealing ring assembly assembly 3340, which then assembles the fifth sealing ring onto the central tube 19.

[0104] Furthermore, the fifth sealing ring transport assembly 3330 includes a fifth sealing ring moving mechanism 3331 and a fifth sealing ring fitting mechanism, a first sealing ring unloading mechanism 3333, a fifth sealing ring inner support mechanism, and a second sealing ring unloading mechanism 3335 connected to the fifth sealing ring moving mechanism 3331. The fifth sealing ring fitting mechanism includes a fifth sealing ring sleeve rod 3332, and the first sealing ring unloading mechanism 3333 includes a first pusher sleeve 33331 sleeved on the outside of the fifth sealing ring sleeve rod 3332. The fifth sealing ring sleeve rod 3332 is used to insert the fifth sealing ring so that the fifth sealing ring is fitted onto the fifth sealing ring sleeve rod 3332, thereby obtaining the fifth sealing ring. The first pusher sleeve 33331 can move axially along the fifth sealing ring sleeve rod 3332, which can remove the fifth sealing ring fitted onto the fifth sealing ring sleeve rod 3332 to achieve unloading. The fifth sealing ring inner support mechanism includes multiple fifth sealing ring inner support blocks 3334, and the second sealing ring unloading mechanism 3335 includes a second pusher sleeve 33351 sleeved on the outside of the fifth sealing ring inner support blocks 3334. The fifth sealing ring inner support blocks 3334 clamp the fifth sealing ring by inner support, thereby moving the fifth sealing ring. The second pusher sleeve 33351 can move along the axial direction of the fifth sealing ring, which can remove the fifth sealing ring clamped by the fifth sealing ring inner support blocks 3334 from the fifth sealing ring inner support blocks 3334, thus realizing unloading.

[0105] During operation, the fifth sealing ring moving mechanism 3331 moves the fifth sealing ring sleeve 3332 above the output end of the fifth sealing ring supply assembly 3310, and then drives the fifth sealing ring sleeve 3332 downward, inserting the fifth sealing ring into it. The fifth sealing ring then fits onto the fifth sealing ring sleeve 3332 and moves with it. The fifth sealing ring moving mechanism 3331 then moves the fifth sealing ring sleeve 3332 above the sealing ring oil tank 3320, and then drives it downward to approach the sealing ring oil tank 3320. The first sealing ring feeding mechanism 3333 then moves the first pushing sleeve 33331 downward along the axial direction of the fifth sealing ring sleeve 3332, removing the fifth sealing ring from the sleeve 3332. The fifth sealing ring falls into the sealing ring oil tank 3320 to absorb oil. After that, the fifth sealing ring... The sealing ring moving mechanism 3331 moves the inner support block 3334 of the fifth sealing ring to above the sealing ring oil tank 3320, and then drives the inner support block 3334 of the fifth sealing ring to move downward, inserting the inner support block 3334 of the fifth sealing ring into the inner side of the fifth sealing ring. The inner support mechanism of the fifth sealing ring then opens the inner support block 3334 of the fifth sealing ring to clamp the fifth sealing ring with the inner support. The fifth sealing ring moving mechanism 3331 moves the inner support block 3334 of the fifth sealing ring to above the fifth sealing ring assembly 3340, and then drives the inner support block 3334 of the fifth sealing ring to move downward so that the inner support block 3334 of the fifth sealing ring aligns with the fifth sealing ring assembly 3340. The second pusher sleeve 33351 then moves the second pusher sleeve 33351 downward along the axial direction of the fifth sealing ring, removing the fifth sealing ring from the inner support block 3334 of the fifth sealing ring, and the fifth sealing ring can then be transferred to the fifth sealing ring assembly 3340.

[0106] The fifth sealing ring moving mechanism 3331 may include a fifth sealing ring lateral moving mechanism and a fifth sealing ring vertical moving mechanism connected to the fifth sealing ring lateral moving mechanism. The fifth sealing ring fitting mechanism, the first sealing ring feeding mechanism 3333, the fifth sealing ring inner support mechanism, and the second sealing ring feeding mechanism 3335 are all connected to the fifth sealing ring vertical moving mechanism. The fifth sealing ring lateral moving mechanism is used to drive the fifth sealing ring vertical moving mechanism to move laterally, and the fifth sealing ring vertical moving mechanism is used to drive the fifth sealing ring fitting mechanism, the first sealing ring feeding mechanism 3333, the fifth sealing ring inner support mechanism, and the second sealing ring feeding mechanism 3335 to move vertically.

[0107] The fifth sealing ring sleeve rod 3332 can be designed with a diameter slightly larger than the inner diameter of the fifth sealing ring, so that it can be sleeved on the fifth sealing ring sleeve rod 3332 by utilizing the elastic deformation characteristics of the fifth sealing ring. The fifth sealing ring inner support mechanism includes an inner support driver connected to the fifth sealing ring inner support block 3334, so as to drive the fifth sealing ring inner support block 3334 to move closer to each other or further away from each other. When the fifth sealing ring inner support block 3334 is driven to move closer to each other, the distance between them is reduced, so that it can be inserted into the fifth sealing ring. When the fifth sealing ring inner support block 3334 is moved further away from each other, it can internally support and clamp the fifth sealing ring.

[0108] The fifth sealing ring moving mechanism 3331 can drive the fifth sealing ring sleeve mechanism and the fifth sealing ring inner support mechanism to operate simultaneously. While the fifth sealing ring sleeve rod 3332 obtains the fifth sealing ring and moves it towards the sealing ring oil tank 3320, the fifth sealing ring inner support block 3334 can clamp the fifth sealing ring in the sealing ring oil tank 3320 and move it towards the fifth sealing ring assembly 3340. When the fifth sealing ring moving mechanism 3331 drives the fifth sealing ring sleeve mechanism to reset, it also drives the fifth sealing ring inner support mechanism to reset at the same time. This allows the steps of placing the fifth sealing ring into the sealing ring oil tank 3320 to absorb oil and transferring the oil-absorbed fifth sealing ring to the fifth sealing ring assembly 3340 to be performed simultaneously, thereby further improving production efficiency.

[0109] In some embodiments, a boss may be provided inside the sealing ring oil tank 3320. The fifth sealing ring transport assembly 3330 places the fifth sealing ring on the boss, and the oil in the sealing ring oil tank 3320 just covers the boss, so as to ensure that the fifth sealing ring placed on the boss can be dipped in the oil. At the same time, it can prevent the fifth sealing ring from being immersed in the oil too deeply, which would prevent the fifth sealing ring inner support block 3334 from docking with the fifth sealing ring. The fifth sealing ring inner support block 3334 can be accurately inserted into the inside of the fifth sealing ring, and then the inner support clamps the fifth sealing ring, so as to remove the fifth sealing ring dipped in the oil.

[0110] In some embodiments, the fifth sealing ring assembly 3340 includes a fifth sealing ring rotating mechanism 3341, a fifth sealing ring lateral moving mechanism 3342 connected to the fifth sealing ring rotating mechanism 3341, a sleeve fixing seat 3343 connected to the fifth sealing ring lateral moving mechanism 3342, and a third sealing ring unloading mechanism 3344 connected to the sleeve fixing seat 3343. The fifth sealing ring rotating mechanism 3341 is used to drive the fifth sealing ring lateral moving mechanism 3342 to rotate, and the fifth sealing ring lateral moving mechanism 3342 is used to drive the sleeve fixing seat 3343 to move laterally. A fifth sealing ring sleeve 3345 extending laterally is fixed on the sleeve fixing seat 3343. The third sealing ring unloading mechanism 3344 includes an unloading push plate 3346 sleeved on the outside of the fifth sealing ring sleeve 3345. The unloading push plate 3346 can move axially along the fifth sealing ring sleeve 3345 to remove the fifth sealing ring from the fifth sealing ring sleeve 3345.

[0111] During operation, the fifth sealing ring rotating mechanism 3341 drives the fifth sealing ring transverse moving mechanism 3342 to rotate, which in turn drives the fifth sealing ring sleeve 3345 to rotate and rotate the fifth sealing ring sleeve 3345 to a vertical position. The fifth sealing ring transverse moving mechanism 3342 then drives the fifth sealing ring sleeve 3345 to move vertically upward to dock with the fifth sealing ring conveying assembly 3330, specifically with the inner support block 3334 of the fifth sealing ring. The second pusher sleeve 33351 can then push the fifth sealing ring onto the fifth sealing ring sleeve 3345, so that the fifth sealing ring is fitted onto the fifth sealing ring sleeve 3345. The fifth sealing ring rotation mechanism 3341 then drives the fifth sealing ring sleeve 3345 to rotate to a horizontal state, so that the axial direction of the fifth sealing ring can be parallel to the axial direction of the central tube 19 on the central tube conveying device 3200. The fifth sealing ring transverse movement mechanism 3342 then drives the fifth sealing ring sleeve 3345 to move horizontally toward the central tube 19, so that the fifth sealing ring sleeve 3345 is connected with the central tube 19. The unloading push plate 3346 can move along the axial direction of the fifth sealing ring sleeve 3345 to push the fifth sealing ring from the fifth sealing ring sleeve 3345 onto the central tube 19, thus completing the assembly of the fifth sealing ring.

[0112] Since the movement range of the second pusher sleeve 33351 is limited, and the installation position of the fifth sealing ring on the central tube 19 is still a certain distance from the end face of the central tube 19, this embodiment can set the inner diameter of the fifth sealing ring sleeve 3345 to be larger than the outer diameter of the central tube 19. When the fifth sealing ring transverse movement mechanism 3342 drives the fifth sealing ring sleeve 3345 to align with the central tube 19, the central tube 19 is inserted into the fifth sealing ring sleeve 3345. This allows the installation position of the fifth sealing ring on the central tube 19 to be close to the end of the fifth sealing ring sleeve 3345. The second pusher sleeve 33351 only needs to move a small distance to push the fifth sealing ring to its installation position on the central tube 19. At the same time, the insertion of the central tube 19 into the fifth sealing ring sleeve 3345 can position the central tube 19, making it less likely to shift during the process of fitting the fifth sealing ring, thus ensuring that the fifth sealing ring can be accurately fitted onto the central tube 19. The surface of the central tube 19 may be provided with an annular groove, and the fifth sealing ring is specifically nested in the annular groove to position the fifth sealing ring, restrict the movement of the fifth sealing ring on the surface of the central tube 19, and also make it easier for the fifth sealing ring assembly assembly 3340 to accurately fit the fifth sealing ring onto the central tube 19.

[0113] In some embodiments, the fifth sealing ring supply assembly 3310 includes a fifth sealing ring vibratory plate 3311 and a fifth sealing ring placement seat 3312. The fifth sealing ring placement seat 3312 is provided with a fifth sealing ring placement groove 3313. The fifth sealing ring vibratory plate 3311 is used to transport the fifth sealing rings one by one to the fifth sealing ring placement groove 3313. The fifth sealing ring transport assembly 3330 is used to put the fifth sealing rings in the fifth sealing ring placement groove 3313 into the sealing ring oil tank 3320 to absorb oil.

[0114] The fifth sealing ring vibratory feeder 3311 continuously supplies the fifth sealing rings, and the sequential delivery of the fifth sealing rings avoids interference. The fifth sealing ring placement groove 3313 positions the fifth sealing rings, ensuring they fall accurately into the designated position. This guarantees that the fifth sealing ring transport assembly 3330 can accurately pick up the fifth sealing rings output from the fifth sealing ring vibratory feeder 3311. The sealing ring oil tank 3320 can be mounted on the fifth sealing ring placement seat 3312 to simplify the structure and save costs.

[0115] In some embodiments, the central tube conveying device 3200 includes two central tube conveying plates 3210 extending along the conveying direction of the central tube 19 and a central tube actuating assembly 3220 located between the two central tube conveying plates 3210. Both central tube conveying plates 3210 can be vertically arranged and can be arranged side-by-side along the conveying direction of the central tube 19. The top surface of the central tube conveying plate 3210 is provided with a plurality of central tube placement slots 3211 distributed along the conveying direction. The central tube actuating assembly 3220 is used to actuate the central tubes 19 placed in the central tube placement slots 3211, so that the central tubes 19 sequentially move along the conveying direction to the next central tube placement slot 3211, thereby conveying the central tubes 19.

[0116] The center tube actuation assembly 3220 may include an actuation plate, an actuation plate lifting mechanism connected to the actuation plate, and an actuation plate lateral movement mechanism connected to the actuation plate lifting mechanism. The actuation plate lateral movement mechanism drives the actuation plate lifting mechanism to move back and forth along the conveying direction of the center tube 19, and the actuation plate lifting mechanism drives the actuation plate to move vertically. During operation, the actuation plate lifting mechanism drives the actuation plate to rise, lifting the center tube 19 in the center tube placement slot 3211. The actuation plate lateral movement mechanism then drives the actuation plate lifting mechanism to move along the conveying direction of the center tube 19 to above the next center tube placement slot 3211. The actuation plate lifting mechanism then drives the actuation plate to descend, allowing the center tube 19 on the actuation plate to fall into the next center tube placement slot 3211. Afterwards, the actuation plate lifting mechanism and the actuation plate lateral movement mechanism reset to await the next actuation of the center tube 19.

[0117] In the conveying direction of the central tube 19, the spacing between two adjacent central tube placement slots 3211 is the same, and the actuating plate lifts all the central tubes 19 on the central tube conveying plate 3210 each time. Thus, each time the central tube actuating component 3220 operates, it moves all the central tubes 19 on the central tube conveying plate 3210 to the next central tube placement slot 3211, thereby increasing conveying efficiency. It should be noted that the central tube 19 in the central tube placement slot 3211 closest to the central tube assembly device 3400 will be removed by the central tube assembly device 3400, therefore there will be no conflict when the central tube actuating component 3220 transports the central tube 19.

[0118] In some embodiments, the central tube assembly device 3400 includes a central tube rotation assembly 3410, a second central tube clamp 3420 connected to the central tube rotation assembly 3410, an assembly lateral movement assembly 3430, an assembly vertical movement assembly 3440 connected to the assembly lateral movement assembly 3430, and a third central tube clamp 3450 connected to the assembly vertical movement assembly 3440. The second central tube clamp 3420 and the third central tube clamp 3450 are both used to clamp or release the central tube 19. The central tube rotation assembly 3410 is used to rotate the second central tube clamp 3420 so that the central tube 19 clamped by the second central tube clamp 3420 rotates from a horizontal state to a vertical state. The assembly lateral movement assembly 3430 is used to drive the assembly vertical movement assembly 3440 to move laterally, and the assembly vertical movement assembly 3440 is used to drive the third central tube clamp 3450 to move vertically.

[0119] During operation, the central tube rotating assembly 3410 drives the second central tube clamp 3420 to rotate to a horizontal position. The second central tube clamp 3420 then clamps the central tube 19 conveyed by the central tube conveying device 3200. The central tube rotating assembly 3410 then drives the second central tube clamp 3420 to rotate to a vertical position, making the central tube 19 clamped by the second central tube clamp 3420 vertical, which is convenient for the third central tube clamp 3450 to clamp. The assembly of the lateral movement assembly 3430 can drive the third central tube clamp 3450 to move above the central tube 19 clamped by the second central tube clamp 3420, and the assembly of the vertical movement assembly... The moving component 3440 then drives the third center tube clamp 3450 to move vertically towards the center tube 19 held by the second center tube clamp 3420. The third center tube clamp 3450 clamps the center tube 19 held by the second center tube clamp 3420, and the second center tube clamp 3420 releases its grip on the center tube 19. The assembly lateral movement component 3430 then drives the third center tube clamp 3450 to move above the inner core of the center tube 19 to be assembled. The assembly vertical movement component 3440 then drives the third center tube clamp 3450 to move vertically towards the inner core, so that the center tube 19 is inserted into the inner core, completing the assembly of the center tube 19. Afterwards, the center tube rotation component 3410, the second center tube clamp 3420, the assembly lateral movement component 3430, the assembly vertical movement component 3440, and the third center tube clamp 3450 can all be reset to await the assembly of the next center tube 19.

[0120] It should be noted that the inner core can be transported to the lower part of the third center tube clamp 3450 by other inner core transport mechanisms, and after the center tube 19 is assembled onto the inner core, the inner core transport mechanism can remove the inner core with the center tube 19 already assembled, and at the same time move the inner core of the center tube 19 to be assembled to the lower part of the third center tube clamp 3450.

[0121] In some embodiments, such as Figure 25 As shown, the separator tube assembly device includes a separator tube supply device 910, a separator tube conveying device 920, two fourth sealing ring assembly devices 930, and a separator tube assembly device 940. The separator tube supply device 910 supplies separator tubes 18 to the separator tube conveying device 920, which in turn supplies separator tubes to the separator tube assembly device 940. The two fourth sealing ring assembly devices 930 are located on opposite sides of the conveying path of the separator tubes on the separator tube conveying device, and are used to assemble the fourth sealing rings onto both ends of the separator tubes. This allows the assembly of the fourth sealing rings to be completed during the conveying of the separator tubes. The separator tube assembly device receives the separator tubes with the fourth sealing rings assembled from the separator tube conveying device 920 and then inserts the assembled separator tubes into the second filter cartridge, thereby completing the assembly of the separator tubes. Since both the central tube and the partition tube are tubular structures, they both need to be fitted with sealing rings at their ends before being assembled onto the inner core product. Their structures and assembly processes are similar. The partition tube supply device 910, partition tube conveying device 920, fourth sealing ring assembly device 930 and partition tube assembly device 940 mentioned above can refer to the central tube supply device, central tube conveying device, fifth sealing ring assembly device and central tube assembly device of the above embodiments, and will not be described again here.

Therefore, those skilled in the art will understand that the foregoing description of various embodiments of the invention is illustrative only and not intended to limit the invention as defined by the appended claims and their equivalents.
