Description

Technical Field

[0001] This utility model relates to the field of filters, and in particular to an automatic assembly mechanism for filter sealing rings. Background Technology

[0002] A filter is an accessory that uses filter paper to filter impurities or gases. Generally, it refers to automotive filters, which are engine components. Based on different filtration functions, they are categorized as: oil filters, fuel filters (gasoline filters, diesel filters, oil-water separators, hydraulic filters), air filters, and cabin air filters. Engines typically have three types of filters: air, oil, and fuel, commonly referred to as the "three filters." Adding the cabin air filter, it's commonly called the "four filters." These filters are responsible for filtering the media in the lubrication system, combustion system, engine intake system, and passenger air circulation system, respectively.

[0003] The applicant discloses a continuous assembly mechanism for an automatic assembly machine of filter sealing rings, with publication number "CN215035121U". It includes a worktable, a pressing assembly, and a feeding device. The feeding device includes a feeding frame, a pressing seat, a pusher plate, a discharge plate, and a pusher cylinder. The pusher plate has a pusher notch, and the discharge plate has a discharge notch. The pressing seat has an axially penetrating pressing cavity and a feeding groove. The conveying end of the pusher cylinder is equipped with a carrying cylinder, which is fixedly connected to the pusher plate. The output end of the carrying cylinder has a carrying rod that can extend or retract into the discharge plate. The pusher cylinder drives the pusher plate to reciprocate towards the pressing seat via the carrying cylinder, feeding the sealing ring in the pusher notch into the pressing seat. The carrying cylinder feeds the sealing ring on the discharge plate into the pusher notch via the carrying rod. This continuous assembly mechanism, with continuous feeding and intermittent pressing, greatly improves product assembly efficiency, ensures a stable assembly process, and significantly reduces labor costs.

[0004] However, the continuous assembly mechanism for the aforementioned automatic sealing ring assembly machine still has the following drawbacks:

[0005] First, the aforementioned continuous assembly mechanism can only press the sealing rings onto ordinary filters, and cannot meet the assembly needs of irregularly shaped sealing rings for filters, resulting in poor applicability of the mechanism.

[0006] Secondly, the sealing ring is directly pushed into the push groove of the pressing seat by the push cylinder. The push distance of the push cylinder needs to be manually adjusted, which is cumbersome and cannot meet the needs of automatic reciprocating push.

[0007] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0008] The purpose of this invention is to provide an automatic assembly mechanism for filter sealing rings to solve the above-mentioned problems in the prior art.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic assembly mechanism for filter sealing rings, including a worktable, a pressing assembly for assembling the sealing ring and the filter together on the worktable, and a feeding device for intermittently feeding the sealing ring into the pressing assembly. The pressing assembly includes a pressing seat on the worktable, a fixing device for fixing the filter to the pressing seat, and a pressing device fixed to the pressing seat. A pressing cavity with an axis through the center of the pressing seat is opened, and a snap-fit ​​sleeve is provided at the top of the pressing device. Several abutment openings are opened on the periphery of the pressing seat, and abutment devices are inserted into the abutment openings. A feeding groove communicating with the pressing cavity is opened at one end of the pressing seat corresponding to the pushing device. The feeding device feeds the sealing ring into the pressing device through the feeding groove. The abutment device is used to abut the sealing ring and make the sealing ring fit onto the snap-fit ​​sleeve at the top of the pressing device when the pressing device moves upward.

[0010] By adopting the above technical solution: the feeding device feeds the sealing ring from the feed chute into the pressing seat and places it above the snap-fit ​​sleeve at the top of the pressing device. At this time, the baffle plate is located in the pressing cavity from the baffle opening. Then the pressing device moves upward, and the sealing ring is abutted by the baffle device and expands under force until it is fitted onto the outer periphery of the snap-fit ​​sleeve. After the fitting is completed, the pressing device pauses its upward movement. Then the baffle device moves the part located in the pressing cavity into the baffle opening. The pressing device moves upward again until the sealing ring is pressed into the filter. The sealing ring is then separated from the snap-fit ​​sleeve, realizing the rapid assembly of the sealing ring of the irregularly shaped filter. Compared with the method of directly pressing the sealing ring into the filter, the pressing device adopts segmented pressing, which allows the sealing ring to be better installed into the filter in the irregularly shaped installation position. In addition, snap-fit ​​sleeves of different sizes can be replaced according to the size of the sealing ring and the installation needs of the filter, improving the adaptability of the automatic assembly mechanism of the sealing ring.

[0011] The aforementioned automatic assembly mechanism for filter sealing rings can be further configured as follows: the pressing device includes a first pressing sleeve disposed in the pressing cavity, a second pressing sleeve connected to the bottom of the first pressing sleeve, a fixing device for fixing the filter to the pressing seat, and an electric cylinder slidably connected to the second pressing sleeve for realizing segmented lifting and lowering of the pressing device. A pressing groove is provided at the end of the first pressing sleeve away from the second pressing sleeve. The outer wall of the snap-fit ​​sleeve is in contact with the inner wall of the pressing groove. One end of the snap-fit ​​sleeve is disposed in the pressing groove, and the other end extends out of the pressing groove into the pressing cavity. A first connecting hole is provided at the bottom of the pressing groove. A second connecting hole is provided on the second pressing sleeve corresponding to the first connecting hole. Fixing bolts are inserted in the first connecting hole and the second connecting hole. The snap-fit ​​sleeve can move up and down along the central axis of the pressing groove through the fixing bolts. A spring is abutting between the snap-fit ​​sleeve and the pressing groove. The spring is used to realize the reset of the snap-fit ​​sleeve.

[0012] By adopting the above technical solution: the electric cylinder can effectively control the lifting process of the pressing device, so that the pressing device can accurately realize the sealing ring being snapped into the snap-fit ​​sleeve during the pressing process. At the same time, the first pressing sleeve and the second pressing sleeve are connected by fixing bolts, and the snap-fit ​​sleeve is set at the end of the pressing groove by fixing bolts. The snap-fit ​​sleeve can slide in the pressing groove. When the sealing ring is pressed into the filter, the snap-fit ​​sleeve is forced to move towards the bottom of the pressing groove. At this time, the sealing ring abuts against the outer peripheral end face of the pressing groove. When the snap-fit ​​sleeve is completely placed in the pressing groove, the sealing ring releases its elasticity and is installed on the filter. Then the electric cylinder drives the first pressing sleeve and the second pressing sleeve to move down, and the snap-fit ​​sleeve is reset to the end position of the pressing groove by the spring to perform the next sealing ring snap-fit.

[0013] The above-mentioned automatic assembly mechanism for filter sealing rings can be further configured as follows: a sliding groove is provided at the bottom of the second pressing sleeve, and a pressing rod is provided at the output end of the electric cylinder, the pressing rod being slidably connected in the sliding groove; the fixing bolt is a hollow bolt, and a connecting bolt is passed through the middle of the hollow bolt, one end of the connecting bolt being connected to the middle of the snap-fit ​​sleeve, and the other end passing through the inside of the hollow bolt.

[0014] By adopting the above technical solution, the hollow bolt makes the connection between the first pressing sleeve and the second pressing sleeve more stable, and the connecting bolt through the middle makes the snap-fit ​​sleeve move more quickly in the pressing groove.

[0015] The aforementioned automatic assembly mechanism for filter sealing rings can be further configured as follows: the blocking device includes a blocking plate and a pushing cylinder for moving the blocking plate. The blocking plate includes a first blocking piece, a second blocking piece, and a bending piece. The first blocking piece and the second blocking piece are provided with transverse sliding slots in the middle. The first blocking piece and the second blocking piece are able to pass through different blocking openings and move laterally left and right through the transverse sliding slots. The pushing cylinder is detachably connected to a moving plate. The moving plate is provided with a mounting slot for connecting the blocking plate. The bending piece is provided with several mounting holes. The blocking plate is detachably connected to the moving plate through the mounting holes.

[0016] By adopting the above technical solution: the transverse slot on the stop block allows the first stop plate and the second stop plate to move easily within the stop opening, and the stop block is connected to the moving plate by a bending plate. The push cylinder pushes the moving plate so that the stop block can repeatedly extend and retract within the pressing cavity. The overall structure is relatively simple, and the replacement and maintenance of the stop block are more convenient.

[0017] The aforementioned automatic assembly mechanism for filter sealing rings can be further configured as follows: the fixing device includes a mounting plate disposed above the working plate and a fixing cylinder disposed at one end of the mounting plate corresponding to the pressing seat. A fixing end cover is disposed at the output end of the fixing cylinder. The fixing cylinder drives the fixing end cover to reciprocate towards the pressing seat, thereby fixing the filter on the pressing seat. An adjusting rod is provided between the mounting plate and the fixing cylinder. The fixing cylinder is mounted on the adjusting rod, and the distance between the fixing cylinder and the pressing seat is controlled by adjusting the adjusting rod.

[0018] By adopting the above technical solution: a mounting plate is set above the workbench, and a fixed cylinder is set on the mounting plate to drive the fixed end cover to move axially and fix the filter on the pressing seat. In this way, when the sealing ring is installed through the pressing device, the upper end of the filter can be fixed by the fixed end cover, so that the filter is subjected to relative force at both ends of the axis during the assembly process, thereby improving the stability of the assembly process.

[0019] The aforementioned automatic assembly mechanism for filter sealing rings can be further configured as follows: the feeding device includes a feeding frame, a pusher plate disposed at the end of the feeding frame away from the pressing seat, a discharge plate disposed above the pusher plate and fixedly connected to the feeding frame, and a pusher cylinder disposed on the feeding frame. The pusher plate has a pusher notch at the end facing the pressing seat, and the discharge plate has a discharge notch at the end facing the pressing seat. A conveying cylinder is installed at the conveying end of the pusher cylinder, and the conveying cylinder is fixedly connected to the pusher plate. The output end of the conveying cylinder is provided with a conveying rod, which can extend or retract into the discharge plate. The pusher cylinder drives the pusher plate to reciprocate toward the pressing seat through the conveying cylinder, sending the sealing ring in the pusher notch into the pressing seat. The conveying cylinder sends the sealing ring on the discharge plate to the pusher notch through the conveying rod.

[0020] By adopting the above technical solution: the sealing ring can be placed above the unloading plate manually, by mechanical claws, or by a conveyor belt. The material-carrying cylinder extends into the sealing ring on the unloading plate via the material-carrying rod, and then the pushing cylinder drives the pushing plate to move towards the pressing seat. Subsequently, the sealing ring, which was originally in the pushing slot, is sent from the feeding slot into the pressing cavity of the pressing seat. At the same time as the pushing plate moves, the sealing ring, which was originally on the unloading plate, falls from above the unloading plate through the unloading slot via the material-carrying rod and onto the pushing plate. Then, the material-carrying cylinder retracts the material-carrying rod into the unloading plate or the pushing plate, away from the sealing ring. Then, the pushing cylinder drives the pushing plate to reset. At this time, the sealing ring on the pushing plate is driven back to its original position by the pushing plate and is blocked by the unloading slot until the sealing ring falls into the pushing slot. This achieves continuous material replenishment. This continuous assembly mechanism with continuous material replenishment and intermittent pressing greatly improves the assembly efficiency of the product, and the assembly process is stable, which greatly reduces labor costs.

[0021] The above-mentioned automatic assembly mechanism for filter sealing rings can be further configured as follows: a conveying device is connected to the end of the feeding device away from the workbench, the conveying device includes a conveying frame, conveying rollers are provided at both ends of the conveying frame, a conveyor belt is provided on the conveying rollers, a drive motor is connected to the conveying rollers, the drive motor is fixed to the side wall of the conveying frame, a fixed plate is provided at the bottom of the conveying frame, a pushing cylinder is detachably connected to the fixed plate, an installation block is provided at the top of the fixed plate, a limiting rod is provided between the installation blocks, a limiting block perpendicular to the conveyor belt is connected to the limiting rod, a pressing block is provided in the middle of the limiting block, and a pressing plate is slidably connected to the pressing block.

[0022] By adopting the above technical solution: the sealing ring can quickly enter the feeding device through the conveying device. The sealing ring is placed on the conveyor belt on the conveyor roller, and the limiting blocks on both sides of the conveyor belt keep the sealing ring on the same axis. The drive motor rotates to move the sealing ring on the conveyor belt toward the feeding device. In addition, when the feeding efficiency of the feeding device is lower than the conveying efficiency of the conveyor, the pressure block is moved down to a specified height to reduce the transmission speed of the sealing ring on the conveyor belt, thereby preventing the sealing ring from accumulating at the feeding device and improving the stability of the feeding device.

[0023] The above-mentioned automatic assembly mechanism for filter sealing rings can be further configured as follows: limiting blocks are provided on both sides of the unloading plate, and several adjustment slots are provided on the limiting blocks. Adjustment knobs are provided in the adjustment slots, and knob blocks are provided on the top of the adjustment knobs. One end of the adjustment knob is threadedly connected to the unloading plate, and the other end is connected to the limiting block through the knob block. A laser sensor is provided on the side of the unloading plate near the worktable of the limiting block. The laser sensor is detachably connected to the unloading plate through a fixing block.

[0024] By adopting the above technical solution, the limiting block can effectively restrict the position of the sealing ring entering the unloading plate through the transmission belt, preventing the sealing ring from being outside the conveyor bar. By loosening the adjustment knob, the width of the limiting block can be adjusted through the adjustment groove, which can be adjusted according to different production needs and adapt to the assembly of various filter sealing rings. At the same time, after the laser sensor detects that the sealing ring has moved to the designated position, it transmits the signal to the pushing cylinder and the conveying cylinder, and the stacking cylinder and the conveyor begin to operate, realizing a high degree of automation in feeding, reducing the possibility of human error, and improving the accuracy and reliability of assembly.

[0025] The above-mentioned automatic assembly mechanism for filter sealing rings can be further configured as follows: a slide rail is provided at the bottom of the feeding rack on the side of the feeding cylinder, a slider is slidably connected on the slide rail, a connecting block is connected to the conveying end of the pushing cylinder, the slider is linked with the pushing cylinder through the connecting block, a first extrusion sensor is provided on the fixed plate, a second extrusion sensor is provided on the feeding rack at a horizontal position relative to the first extrusion sensor, an extrusion plate is provided on the connecting block, the extrusion plate is provided with an extrusion part for extrusion, and the first extrusion sensor and the second extrusion sensor are signal connected to the feeding device.

[0026] By adopting the above technical solution: while the pushing cylinder pushes the material-carrying cylinder towards the pressing seat, the slider moves synchronously with the material-carrying cylinder through the connecting block. When the extrusion plate on the connecting block comes into contact with the second extrusion sensor, the second extrusion sensor transmits a signal to the control panel. The control panel stops the movement of the pushing cylinder and controls the pushing cylinder to reset. When the extrusion plate comes into contact with the first extrusion sensor, the first extrusion sensor transmits a signal to the control panel again. The control panel controls the pushing cylinder to push the material, ensuring accurate feeding and synchronous movement of the sealing ring.

[0027] The above-mentioned automatic assembly mechanism for filter sealing rings can be further configured as follows: the unloading plate is provided with guide grooves on both sides of the unloading slot, the guide grooves are provided with guide blocks, and the guide grooves are provided with baffles that are linked to the unloading plate. The baffles can move relative to the unloading plate along the unloading plate.

[0028] By adopting the above-mentioned technical solution, when the pusher plate moves towards the feed chute, the baffle plate moves relative to the unloading plate, which can effectively prevent the sealing ring from detaching from the pusher plate when the material rod is carrying material, thus improving the stability of the sealing ring on the pusher plate.

[0029] The beneficial effects of this utility model are as follows:

[0030] First, when the filter moves to the pressing seat, the pressing device and the baffle device cooperate with each other. When the feeding device sends the sealing ring to the pressing cavity of the pressing seat, the pressing device first moves upward a certain distance so that the sealing ring comes into contact with the baffle device and undergoes elastic deformation until it is snapped into the snap sleeve above the pressing device. Then the baffle device moves the part inside the pressing cavity into the baffle opening. Subsequently, the pressing device moves towards the filter again until the sealing ring is installed in the filter. This can be used to assemble traditional filter seals and can also quickly and automatically install the sealing ring in the designated position of irregularly shaped filters, improving the adaptability of the automatic assembly mechanism.

[0031] Secondly, the feeding device, combined with laser sensors and compression sensors, can automatically control the feeding and resetting of the seals, improving the automation level of the automatic assembly mechanism. The baffle plate can effectively prevent the seals above the pusher plate from detaching from the conveyor belt rod when pushing the material. At the same time, the pressure block is set on the conveyor belt umbrella, which can effectively reduce the risk of the seals falling off.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0045] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] An automatic assembly mechanism for filter sealing rings includes a worktable 1, a pressing assembly mounted on the worktable 1 for assembling the sealing ring and the filter together, and a feeding device 3 for intermittently feeding the sealing ring into the pressing assembly. The pressing assembly includes a pressing seat 11 mounted on the worktable 1, a fixing device 4 for fixing the filter to the pressing seat 11, and a pressing device 2 fixed to the pressing seat 11. The pressing seat 11 has a pressing cavity 111 with an axis through it in the middle. The pressing device 2 has a snap-fit ​​sleeve 24 at the top. The pressing seat 11 has several abutment openings 112 on its periphery. Abutment devices 5 pass through the abutment openings 112. The pressing seat 11 has a feed groove 113 at one end corresponding to the feeding device, which communicates with the pressing cavity 111. The feeding device 3 feeds the sealing ring into the pressing device 2 through the feed groove 113. The abutment devices 5 are used to abut the sealing ring and make the sealing ring fit onto the snap-fit ​​sleeve 24 at the top of the pressing device 2. After the feeding device 3 feeds the sealing ring from the feed trough 113 into the pressing seat 11 and places it on the snap sleeve 24 at the top of the pressing device 2, the baffle plate 51 is located from the abutment opening 112 to the pressing cavity 111. The pressing device 2 moves upward, and the sealing ring is abutted by the baffle device 5 and expanded by force until it is fitted onto the outer periphery of the snap sleeve 24. Then the baffle device 5 moves the part located in the pressing cavity 111 to the abutment opening 112. The pressing device 2 moves upward again until the sealing ring is pressed into the filter. The sealing ring is separated from the snap sleeve 24, realizing the rapid assembly of the sealing ring of the irregular filter. Compared with the method of directly pressing the sealing ring into the filter, the pressing device 2 adopts segmented pressing, which makes the sealing ring better installed in the filter. In addition, the snap sleeve 24 of different sizes can be replaced according to the installation needs of the sealing ring and the filter, which improves the adaptability of the automatic assembly mechanism of the sealing ring.

[0047] The pressing device 2 includes a first pressing sleeve 21 disposed in the pressing cavity 111, a second pressing sleeve 22 connected to the bottom of the first pressing sleeve 21, a fixing device 4 for fixing the filter to the pressing seat 11, and an electric cylinder 23 slidably connected to the second pressing sleeve 22 for realizing the segmented lifting and lowering of the pressing device 2. The first pressing sleeve 21 has a pressing groove 211 at the end away from the second pressing sleeve 22. The snap-fit ​​sleeve 24 is located at the end of the pressing groove 211. The bottom of the pressing groove 211 has a first connecting hole 212. The second pressing sleeve 22 has a second connecting hole 221 corresponding to the first connecting hole 212. Fixing bolts 222 pass through the first connecting hole 212 and the second connecting hole 221. The snap-fit ​​sleeve 24 can move up and down along the central axis of the pressing groove 211 through the fixing bolts 222. A spring 213 is abutting between the snap-fit ​​sleeve 24 and the pressing groove 211. The spring 213 is used to realize the reset of the snap-fit ​​sleeve 24. The electric cylinder 23 can effectively control the lifting process of the pressing device 2, so that the pressing device 2 can accurately realize the sealing ring being inserted into the snap-fit ​​sleeve 24 during the pressing process. At the same time, the first pressing sleeve 21 and the second pressing sleeve 22 are connected by the fixing bolt 222. The snap-fit ​​sleeve 24 is set at the end of the pressing groove 211 by the fixing bolt 222. The snap-fit ​​sleeve 24 can slide in the pressing groove 211. When the sealing ring is pressed into the filter, the snap-fit ​​sleeve 24 is forced to move towards the bottom of the pressing groove 211. At this time, the sealing ring abuts against the outer peripheral end face of the pressing groove 211. When the snap-fit ​​sleeve 24 is completely placed in the pressing groove 211, the sealing ring releases its elasticity and is installed on the filter. Then the electric cylinder 23 drives the first pressing sleeve 21 and the second pressing sleeve 22 to move down. The snap-fit ​​sleeve 24 is reset to the end position of the pressing groove 211 by the spring 213 to perform the next sealing ring snap-fit.

[0048] The bottom of the second pressing sleeve 22 has a sliding groove 224, and the output end of the electric cylinder 23 has a pressing rod 231, which is slidably connected in the sliding groove 224. The fixing bolt 222 is a hollow bolt, and a connecting bolt 223 is inserted through the middle of the hollow bolt. One end of the connecting bolt 223 is connected to the middle of the snap-fit ​​sleeve 24, and the other end is inserted inside the hollow bolt. The hollow bolt makes the connection between the first pressing sleeve 21 and the second pressing sleeve 22 more stable, and the connecting bolt 223 inserted in the middle allows the snap-fit ​​sleeve 24 to move more quickly in the pressing groove 211.

[0049] The blocking device 5 includes a blocking plate 51 and a pushing cylinder 52 for moving the blocking plate 51. The blocking plate 51 includes a first blocking piece 511, a second blocking piece 512, and a bent piece 513. The first blocking piece 511 and the second blocking piece 512 are provided with a transverse sliding slot 515 in the middle. The first blocking piece 511 and the second blocking piece 512 can pass through different blocking openings 112 and can move left and right through the transverse sliding slot 515. The pushing cylinder 52 is detachably connected to a moving plate 521. The moving plate 521 has a mounting slot 522 for connecting the blocking plate 51. The bent piece 513 has a plurality of mounting holes 514. The blocking plate 51 is detachably connected to the moving plate 521 through the mounting holes 514. The transverse slot 515 on the stop block allows the first stop plate 511 and the second stop plate 512 to move easily within the stop opening 112. The stop block is connected to the moving plate 521 by the bending plate 513. The push cylinder 52 pushes the moving plate 521 so that the stop block can repeatedly extend and retract within the pressing cavity 111. The overall structure is relatively simple, and the replacement and maintenance of the stop block are more convenient.

[0050] The fixing device 4 includes a mounting plate 41 positioned above the worktable, and a fixing cylinder 42 positioned at one end of the mounting plate 41 corresponding to the pressing seat 11. A fixing end cap 43 is provided at the output end of the fixing cylinder 42. The fixing cylinder 42 drives the fixing end cap 43 to reciprocate towards the pressing seat 11, thereby fixing the filter onto the pressing seat 11. An adjusting rod 44 is provided between the mounting plate 41 and the fixing cylinder 42. The fixing cylinder 42 is mounted on the adjusting rod 44, and the distance between the fixing cylinder 42 and the pressing seat 11 is controlled by adjusting the adjusting rod 44. The mounting plate 41 is positioned above the worktable 1, and the fixing cylinder 42 on the mounting plate 41 drives the fixing end cap 43 to move axially, fixing the filter onto the pressing seat 11. This ensures that when the sealing ring is installed via the pressing device 2, the upper end of the filter can be fixed by the fixing end cap 43, allowing the filter to be subjected to relative axial force at both ends during assembly, thus improving the stability of the assembly process.

[0051] The feeding device 3 includes a feeding frame 31, a pusher plate 32 disposed at the end of the feeding frame 31 away from the pressing seat 11, a discharge plate 33 disposed above the pusher plate 32 and fixedly connected to the feeding frame 31, and a pusher cylinder 321 disposed on the feeding frame 31. The pusher plate 32 has a pusher notch 322 at the end facing the pressing seat 11, and the discharge plate 33 has a discharge notch at the end facing the pressing seat 11. A feeding cylinder 3 is installed at the conveying end of the pusher cylinder 321. 23. The material-carrying cylinder 323 is fixedly connected to the pusher plate 32. The output end of the material-carrying cylinder 323 is provided with a material-carrying rod 324. The material-carrying rod 324 can extend or retract into the unloading plate 33. The pusher cylinder 321 drives the pusher plate 32 to reciprocate towards the pressing seat 11 through the material-carrying cylinder 323, sending the sealing ring in the pusher notch 322 into the pressing seat 11. The material-carrying cylinder 323 sends the sealing ring on the unloading plate 33 into the pusher notch 322 through the material-carrying rod 324. The sealing ring can be placed above the unloading plate 33 manually, by a mechanical claw, or by a conveyor belt 63. The feeding cylinder 323 extends into the sealing ring on the unloading plate 33 via the feeding rod 324. Then, the pushing cylinder 321 moves the pushing plate 32 towards the pressing seat 11. The sealing ring, originally in the pushing notch 322, is then fed from the feeding groove 113 into the pressing cavity 111 of the pressing seat 11. Simultaneously with the movement of the pushing plate 32, the sealing ring, originally on the unloading plate 33, is fed from above the unloading plate 33 via the feeding rod 324 through the unloading notch. The groove falls onto the pusher plate 32 at this time, and then the material-carrying cylinder 323 retracts the material-carrying rod 324 into the unloading plate 33 or the pusher plate 32 to leave the sealing ring. Then the pusher cylinder 321 drives the pusher plate 32 to reset. At this time, the sealing ring on the pusher plate 32 is driven back to its original position by the pusher plate 32 and is blocked by the unloading groove until the sealing ring falls into the pusher groove 322, realizing continuous material replenishment. This continuous material replenishment and intermittent pressing continuous assembly mechanism greatly improves the assembly efficiency of the product, and the assembly process is stable, greatly reducing labor costs.

[0052] The feeding device 3 is connected to a conveying device 6 at the end away from the workbench 1. The conveying device 6 includes a conveying frame 61, with conveying rollers 62 at both ends of the conveying frame 61. A conveyor belt 63 is provided on the conveying rollers 62. The conveying rollers 62 are connected to a drive motor 64, which is fixed to the side wall of the conveying frame 61. A fixing plate 65 is provided at the bottom of the conveying frame 61. A pushing cylinder 321 is detachably connected to the fixing plate 65. A mounting block 66 is provided at the top of the fixing plate 65. A limiting rod 661 is provided between the mounting blocks 66. The limiting rod 661 is connected to a limiting block 662 perpendicular to the conveyor belt 63. A pressing block 663 is provided in the middle of the limiting block 662. A pressing plate 664 is slidably connected to the pressing block 663. The sealing ring can be quickly fed into the feeding device 3 via the conveyor device 6. The sealing ring is placed on the conveyor belt 63 on the conveyor roller 62. Limiting blocks 662 on both sides of the conveyor belt 63 keep the sealing ring on the same axis. The drive motor 64 rotates, causing the sealing ring on the conveyor belt 63 to move towards the feeding device 3. Furthermore, when the feeding efficiency of the feeding device 3 is lower than the conveying efficiency of the conveyor device 6, the pressing block 663 is moved down to a specified height to reduce the transmission speed of the sealing ring on the conveyor belt, preventing the sealing ring from accumulating at the feeding device 3 and improving the stability of the feeding device 3.

[0053] Material limiting blocks 331 are provided on both sides of the unloading plate 33. Several adjustment slots 332 are provided on the material limiting blocks 331. Adjustment knobs 333 are provided in the adjustment slots 332. A knob block is provided on the top of the adjustment knobs 333. One end of the adjustment knob 333 is threadedly connected to the unloading plate 33, and the other end is connected to the material limiting blocks 331 through the knob block. A laser sensor 334 is provided on the side of the unloading plate 33 near the workbench 1 of the material limiting block 331. The laser sensor 334 is detachably connected to the unloading plate 33 through the fixing block 335. The limiting block 331 effectively restricts the sealing ring from entering the unloading plate 33 via the transmission belt, preventing the sealing ring from being outside the conveyor bar 324. By loosening the adjustment knob 333, the limiting block 331 can be adjusted in width via the adjustment groove 332, which can be adjusted according to different production needs to adapt to the assembly of various filter sealing rings. At the same time, after the laser sensor 334 detects that the sealing ring has moved to the designated position, it transmits the signal to the pushing cylinder 321 and the conveying cylinder 323, and the stacking cylinder and conveyor begin to operate, realizing a high degree of automation in feeding, reducing the possibility of human error, and improving the accuracy and reliability of assembly.

[0054] The bottom of the feeding rack 31 is provided with a slide rail 34 located on the side of the feeding cylinder 323. A slider 341 is slidably connected to the slide rail 34. A connecting block 342 is connected to the conveying end of the pushing cylinder 321. The slider 341 is linked with the pushing cylinder 321 through the connecting block 342. A first extrusion sensor 343 is provided on the fixed plate 65. A second extrusion sensor 344 is provided on the feeding rack 31 at a horizontal position relative to the first extrusion sensor 343. An extrusion plate 345 is provided on the connecting block 342. The extrusion plate 345 is provided with an extrusion part for extrusion. The first extrusion sensor 343 and the second extrusion sensor 344 are signal connected to the feeding device 3. While the pushing cylinder 321 pushes the conveying cylinder 323 toward the pressing seat 11, the slider 341 moves synchronously with the conveying cylinder 323 through the connecting block 342. When the extrusion plate 345 on the connecting block 342 comes into contact with the second extrusion sensor 344, the second extrusion sensor 344 transmits a signal to the control panel. The control panel stops the movement of the pushing cylinder 321 and controls the pushing cylinder 321 to reset. When the extrusion plate 345 comes into contact with the first extrusion sensor 343, the first extrusion sensor 343 transmits a signal to the control panel again. The control panel controls the pushing cylinder 321 to push the material, ensuring accurate feeding and synchronous movement of the sealing ring.

[0055] The unloading plate 33 has guide grooves 35 on both sides of the unloading slot, and guide blocks 351 are provided on the guide grooves 35. A baffle plate 352 that is linked with the unloading plate 33 is provided in the guide grooves 35. The baffle plate 352 can move relative to the unloading plate 33 along the unloading plate 33. When the pusher plate 32 moves toward the feed chute 113, the baffle plate 352 moves relative to the unloading plate 33, which can effectively prevent the sealing ring from detaching from the pusher plate 32 when the material rod 324 is carrying material, thus improving the stability of the sealing ring on the pusher plate 32.
