Description

Technical Field

[0001] This invention relates to the field of atomizer technology, and in particular to an atomizer core assembly device and processing method. Background Technology

[0002] The atomizer coil is a key component of an atomizer, producing an atomization effect by converting liquid into fine particles. The atomizer coil mainly consists of a heating wire, wicking material, a rod, and a shell. Existing atomizer coil assembly equipment suffers from the following two shortcomings:

[0003] (1) Existing atomizer core assembly equipment still relies on some manual operation. When large-scale production is required, the labor cost is high, and manual operation may have errors, resulting in poor production results.

[0004] (2) Existing atomizer core assembly equipment is only suitable for assembling atomizer cores with openings in the atomizer core shell. Usually, after the atomizer core is assembled, the excess oil-guiding cotton at the opening is trimmed, and the material is unloaded after trimming. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides an assembly device and processing method for atomizing cores. The processing method uses the assembly device, which divides the production of atomizing cores into multiple workstations for separate processing, thereby achieving fully automated production of atomizing cores and saving labor costs. The position of the cotton-cutting mechanism in the assembly device can be adjusted according to actual conditions, making it suitable for assembly scenarios where the atomizing core shell has an opening or not.

[0006] The technical solution adopted by this invention to solve its technical problem is:

The oil-wicking cotton picking assembly is located on one side of the oil-wicking cotton conveying platform and is used to pick up the oil-wicking cotton peeled off from the upper end of the oil-wicking cotton conveying platform and place it into the initial placement position of the fixture.

[0009] Furthermore, the heating wire feeding mechanism includes a heating wire conveying track, a displacement component, a cutting component, and a heating wire picking component. The heating wire conveying track includes a first track that is inclined downward and a second track that is horizontally arranged. The first end of the second track is connected to the end of the first track. The heating wire picking component is located at the end of the second track and is used to pick up the heating wire and place it into the initial placement position of the fixture.

[0010] Furthermore, the round bar feeding mechanism includes a first hopper and a feeding platform disposed below the first hopper. One end of the feeding platform is provided with a second groove, the outline of which is adapted to the outer circumferential outline of the round bar. The other end of the feeding platform is provided with a feeding platform pushing device. One end of the second groove is provided with a second rotating clamping assembly, and the other end of the second groove is provided with a round bar driving device. Above the second rotating clamping assembly is a round bar picking assembly, which is used to pick up the round bar and place it into the initial placement position of the fixture.

[0011] Furthermore, the round bar assembly includes a horizontally arranged first moving module, on which a winding robot is provided. The winding robot is used to clamp the oil-guiding cotton and push it to the product installation position to realize the cotton winding operation.

[0012] Furthermore, the outer shell feeding mechanism includes an outer shell conveying line, a film tearing mechanism, and an outer shell picking assembly. The outer shell conveying line is used to convey the film with the outer shell attached. The film tearing mechanism is located at the end of the outer shell conveying line and is used to tear off the film attached to the surface of the outer shell. The outer shell picking assembly is used to clamp the outer shell after the film has been torn off and assemble it to the outer periphery of the oil-guiding cotton in the product mounting position.

[0013] Furthermore, the film-tearing mechanism includes a film-tearing unit and a film-tearing driving device. The end of the film-tearing unit has a U-shaped opening, and both ends of the U-shaped opening are provided with protruding structures facing the product conveyor line. The middle of the protruding structure has an opening for the film to pass through. The film-tearing driving device is used to drive the film-tearing unit to swing to tear the film.

[0014] Furthermore, the gear plug feeding mechanism includes a feeding device, a gear plug picking assembly, and a gear plug positioning assembly. The feeding device includes a second hopper and a gear plug conveying track.

The gear plug feeding assembly is located below the second hopper. The gear plug picking assembly is used to pick up the gear plug and assemble it into the product mounting position of the fixture.

[0015] The present invention also provides a method for processing an atomizing core, which is performed using the atomizing core assembly equipment described above, and includes the following steps:

[0016] Step 1: Feeding the oil-guiding cotton. The oil-guiding cotton is fed through the unwinding component, the winding component, and the oil-guiding cotton conveying platform in the oil-guiding cotton feeding mechanism. The oil-guiding cotton picking component picks up the oil-guiding cotton and places it into the initial placement position of the fixture.

[0017] Step 2: Heating wire feeding. The oil-guiding cotton is fed through the heating wire conveying track, displacement component, and cutting component in the heating wire feeding mechanism. The heating wire picking component picks up the heating wire and places it into the initial placement position of the fixture.

[0018] Step 3: Round bar feeding and cotton winding. The round bars are conveyed through the first hopper and the feeding platform in the round bar feeding mechanism. The round bar picking assembly picks up the round bars and puts them into the initial placement position of the fixture. Then, the cotton winding assembly pushes the oil-guiding cotton from the initial placement position to the product installation position. During the pushing process, the oil-guiding cotton can wind the heating wire and the round bar into it to realize the cotton winding work.

[0019] Step 4: Shell loading. The shell is conveyed through the shell conveyor line and film tearing mechanism in the shell loading mechanism. The shell is picked up by the shell picking assembly and placed into the product mounting position of the fixture. The notch on the shell is aligned with the part of the oil-guiding cotton that extends out of the product mounting position and inserted. It is then fitted onto the outer periphery of the oil-guiding cotton, heating wire and round rod that have undergone the cotton rolling process.

[0020] Step 5: Gear plug feeding. The gear plug is fed by the feeding device in the gear plug feeding mechanism. The gear plug picking assembly and the gear plug positioning assembly work together to assemble the gear plug into the housing along the fifth through hole in the positioning block.

[0021] Step Six: Unloading. The sixth robotic arm is driven by the sixth robotic arm drive device to clamp the assembled product and move it to the unloading trough for unloading.

[0022] Furthermore, before performing step three or four, a cotton-cutting process is also included, in which excess oil-guiding cotton is trimmed by a cotton-cutting mechanism.

[0023] The beneficial effects of this invention are:

[0024] This invention provides an assembly device and processing method for atomizing cores. The processing method uses the assembly device, which divides the production of atomizing cores into multiple workstations for separate processing, enabling fully automated production of atomizing cores and saving labor costs. The position of the cotton-cutting mechanism in the assembly device can be adjusted according to actual conditions, making it suitable for assembly scenarios where the atomizing core shell has an opening or not.

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0045] Example 1:

[0046] Reference Figures 1 to 14 as well as Figure 18 The present invention provides an assembly device for atomizing cores, including a frame 1. The frame 1 includes an upper sealing plate and several sealing plates surrounding the upper sealing plate. The upper sealing plate is provided with a turntable 10 and a turntable drive device for controlling the rotation of the turntable 10. Several jigs 11 are fixedly provided on the turntable 10 and rotate with the turntable 10. The jigs 11 are provided with product mounting positions 110 and initial placement slots. The initial placement slots are used to place the oil-guiding cotton, heating wire and round rod to be assembled. The product mounting positions 110 are used for rolling cotton, installing the outer shell and gear plug.

[0047] The outer periphery of the turntable 10 is sequentially equipped with an oil-guiding cotton feeding mechanism 2, a heating wire feeding mechanism 3, a round bar feeding mechanism 4, a housing feeding mechanism 6, a gear plug feeding mechanism 7, and a discharging mechanism. The round bar feeding mechanism 4 includes a cotton-winding assembly, which pushes the oil-guiding cotton from the initial placement slot to the product mounting position 110. During the pushing process, the oil-guiding cotton wraps around the heating wire and the round bar and moves together. The housing feeding mechanism 6 includes a housing assembly assembly, which assembles the housing onto the outer periphery of the oil-guiding cotton in the product mounting position 110. The gear plug feeding assembly includes a gear plug assembly assembly, which assembles the gear plug into the interior of the housing in the product mounting position 110.

[0048] The oil-guiding cotton feeding mechanism 2 includes a support 20, an unwinding assembly, a winding assembly, an oil-guiding cotton conveying platform 22, and an oil-guiding cotton picking assembly 29. The film with oil-guiding cotton adhering to it passes through the unwinding assembly, the oil-guiding cotton conveying platform 22, and the winding assembly in sequence to complete the conveyor belt operation.

[0049] The unwinding assembly includes an unwinding reel 27 and an unwinding roller 211, and the winding assembly includes a winding reel 28 and a winding roller 212. The unwinding reel 27 and the winding reel 28 are mounted on the same optical axis, which is fixedly connected to the support 20 via a crossbeam 26. The unwinding roller 211 and the winding roller 212 are connected to the support 20 via a roller frame 21. A rotating roller 210 is mounted on the roller frame 21. One end of the rotating roller 210 extends to the outside of the support 20 and is connected to a rotating roller drive device 24 via a synchronous belt drive assembly. The rotating roller drive device 24 is fixed to the support 20 and can drive the rotating roller 210 to rotate. The take-up roller 212 and the unwind roller 211 are located on opposite sides of the rotating roller 210 and are in contact with the rotating roller 210. The ends of the take-up roller 212 and the unwind roller 211 are connected to the roller frame 21 through bushings. When the rotating roller 210 rotates under the control of the rotating roller drive device 24, the take-up roller 212 and the unwind roller 211 can be driven to rotate by friction. Only one rotating roller drive device 24 is needed to achieve synchronous drive of unwinding and take-up.

[0050] The unwinding assembly and the rewinding assembly are located on the same side of the oil-guiding cotton conveying platform 22. Several guide rollers 25 are arranged below the oil-guiding cotton conveying platform 22 to guide the conveyor belt. The film released from the unwinding reel 27 passes through the unwinding roller 211 along the upper surface of the oil-guiding cotton conveying platform 22, then through the guide rollers 25 and the rewinding roller 212, and is wound onto the rewinding reel 28. The end of the oil-guiding cotton conveying platform 22 furthest from the unwinding assembly and the rewinding assembly is the oil-guiding cotton peeling point. When the film passes this end, it will change direction under the pull of the unwinding roller 211 and the rewinding roller 212, and the oil-guiding cotton adhering to the film surface will be peeled off from the film surface under the pulling action.

[0051] An oil-absorbing cotton receiving assembly 29 is disposed on one side of the oil-absorbing cotton conveying platform 22 and is used to clamp the oil-absorbing cotton peeled off from the upper end of the oil-absorbing cotton conveying platform 22. Specifically, an oil-absorbing cotton detection unit 23 is disposed on the side of the oil-absorbing cotton conveying platform 22 near the oil-absorbing cotton receiving assembly 29. The oil-absorbing cotton detection unit 23 is fixedly connected to the bracket 20 and is used to detect whether there is oil-absorbing cotton at the end of the oil-absorbing cotton conveying platform 22. The oil-absorbing cotton receiving assembly 29 includes a first rotating clamping assembly 292, which is used to receive the oil-absorbing cotton peeled off from the end of the oil-absorbing cotton conveying platform 22. The first rotating clamping assembly 292 includes a receiving fixture 2920, which is provided with a plurality of oil-absorbing cotton placement grooves. In this embodiment, the oil-absorbing cotton placement grooves are arranged in two rows to receive oil-absorbing cotton peeled off twice. The oil-guiding cotton assembly 29 also includes a first robotic arm 291 and a first robotic arm drive device 290 disposed above the first rotary clamping assembly 292. The first robotic arm drive device 290 is used to control the position of the first robotic arm 291, and the first robotic arm 291 is used to grip the oil-guiding cotton.

[0052] The heating wire feeding mechanism 3 includes a heating wire conveying track, a displacement component, a cutting component, and a heating wire picking component 36. The heating wire conveying track includes a downwardly inclined first track 30 and a horizontally arranged second track 31, with the first end of the second track 31 connected to the end of the first track 30. The heating wire picking component 36 includes a second robotic arm 361 and a second robotic arm drive device 360. The second robotic arm drive device 360 ​​is used to control the position of the second robotic arm 361, and the second robotic arm 361 is used to pick up the heating wire.

[0053] The displacement assembly includes a first displacement assembly disposed at the beginning of the second track 31 and a second displacement assembly disposed at the end of the second track 31. The first displacement assembly includes a first moving block 320 and a first displacement driving device 32 for driving the first moving block 320. The first moving block 320, connected to its output shaft, has a triangular structure. A first through hole 312 is provided on the side of the second track 31, and the triangular end of the first moving block 320 is positioned facing the first through hole 312. The first displacement driving device 32 can drive the triangular end of the first moving block 320 to move into the first through hole 312, thereby moving the heating wire on the beginning of the second track 31.

[0054] The second displacement component includes a second moving block 381 and a second displacement driving device 38 for driving the displacement of the second moving block 381. The second moving block 381 is also a triangular structure. A second through hole is provided on the side of the second track 31. The second displacement driving device 38 can drive the triangular end of the second moving block 381 to move into the second through hole, thereby pushing the heating wire on the end of the second track 31 to move.

[0055] Heating wire detection units 310 are provided at both the beginning and end of the second track 31. When the heating wire detection unit 310 at the beginning of the second track 31 detects the heating wire, it controls the first displacement driving device 32 to drive the first moving block 320 to move and drive the heating wire to move. When the heating wire detection unit 310 at the end of the second track 31 detects the heating wire, it controls the second displacement driving device 38 to drive the second moving block 381 to move and drive the heating wire to move.

[0056] The cutting assembly includes a first fixing seat disposed on a first mounting plate, a first groove communicating with a second track 31 on the first fixing seat, and a first pushing assembly and a second pushing assembly disposed on both sides of the first groove. The coiled heating wire is cut into individual heating wires by the pushing force between the first pushing assembly and the second pushing assembly.

[0057] The first pushing assembly includes a first cylinder 34 and a first pushing block 342 connected to the output shaft of the first cylinder 34. The second pushing assembly includes a second cylinder 33 and a second pushing block 331 connected to the output shaft of the second cylinder 33. The driving force of the first cylinder 34 is greater than the driving force of the second cylinder 33. In this embodiment, the cylinder diameter of the first cylinder 34 is larger than the cylinder diameter of the second cylinder 33. When the same air pressure is supplied to both, the thrust achieved by the first cylinder 34 is greater than the thrust achieved by the second cylinder 33. In another specific embodiment, by selecting a first cylinder 34 and a second cylinder 33 with the same cylinder diameter, and ensuring that the air pressure supplied to the first cylinder 34 is greater than the air pressure supplied to the second cylinder 33, the condition that the thrust achieved by the first cylinder 34 is greater than the thrust achieved by the second cylinder 33 can also be satisfied.

[0058] The first cylinder 34 and the second cylinder 33 are disposed on the same side of the first fixed base. The output shaft of the first cylinder 34 is connected to the first push block 342 via a bent first connecting block 341, thus enabling the first push block 342 and the second push block 331 to be arranged opposite each other. In another specific embodiment, the first push assembly and the second push assembly can also be disposed on opposite sides of the first fixed base, which also enables the first push block 342 and the second push block 331 to be arranged opposite each other.

[0059] The round bar feeding mechanism 4 includes a first hopper 40 and a feeding platform 41 disposed below the first hopper 40. One end of the feeding platform 41 has a second groove 412, the contour of which matches the outer circumferential contour of the round bar. The other end of the feeding platform 41 has a feeding platform pushing device 410. In this embodiment, the feeding platform pushing device 410 is a cylinder, and its output shaft is connected to the feeding platform 41. The feeding platform pushing device 410 can drive the feeding platform 41 to slide horizontally along the second guide rail.

[0060] A cover plate is provided above the second groove 412, and a third detection unit is provided on the cover plate. The third detection unit is used to detect whether there is a round bar in the second groove 412, and to determine whether the round bar is ready for the next feeding operation. The round bar feeding mechanism 4 has two vertical first fixing plates 414, and the two ends of the cover plate are respectively connected to the top of the two first fixing plates 414. The vertical height of the feeding platform 41 is equal to the vertical height of the top of the first fixing plate 414, and the top of the first fixing plate 414 is provided with a sliding groove that matches the outer contour of the round bar.

[0061] When the feeding platform pushing device 410 is in the initial position, the round bar is put in through the opening at the top of the first hopper 40. The bottom of the first hopper 40 is inclined and connected to the second groove 412, so that the round bar can slide into the second groove 412. Then, the feeding platform pushing device 410 is controlled to move the feeding platform 41 to the bottom of the cover plate. When the heating wire detection unit 310 detects the round bar, the next round bar feeding operation is carried out.

[0062] A second rotary clamping assembly 42 is provided at one end of the second groove 412, and a round bar driving device 413 is provided at the other end of the second groove 412. The round bar driving device 413 includes a three-way air pipe connector. One of the three-way air pipe connectors is sealed with a plug. One of the remaining two air pipe connectors is fixedly connected to the end of the first groove away from the second rotary clamping assembly 42, and the other air pipe connector is connected to an external positive pressure air source. The round bar is pushed along the first groove and the slide to the second rotary clamping assembly 42 by the air.

[0063] The second rotary clamping assembly 42 includes a clamping plate 422 with a third through hole 4220 and a second clamping cylinder 420. The clamping plate 422 is connected to the second clamping cylinder 420 via a second rotating shaft 421. The contour of the third through hole 4220 is adapted to the contour of the round bar. When the clamping plate 422 is in the initial position, the third through hole 4220 and the second groove 412 are at the same level, so that the round bar driving device 413 can push the round bar along the second groove 412 into the third through hole 4220. A fourth detection unit is provided at the end of the third through hole 4220 away from the second groove 412. The fourth detection unit is used to detect whether there is a round bar in the third through hole 4220.

[0064] Above the second rotary clamping assembly 42 is a round bar picking assembly, which includes a horizontally arranged first moving module 43. A third robotic arm 452 is mounted on the first moving module 43. The third robotic arm 452 is connected to the first moving module 43 via a robotic arm mounting plate 45. A first moving plate 450 is slidably mounted on the robotic arm mounting plate 45. The first moving plate 450 is connected to a moving plate driving device 44, which drives the first moving plate 450 to slide vertically along a third guide rail. The third robotic arm 452 is fixedly mounted on the first moving plate 450 and moves up and down with the first moving plate 450.

[0065] The first moving plate 450 is also equipped with a winding robot 451. After the third robot 452 clamps the round bar on the second rotating clamping assembly 42, the first moving module 43 drives the fourth mounting plate to move horizontally and place the round bar into the initial placement slot on the fixture 11. At this time, the initial placement slot of the fixture 11 already contains the heating wire, oil-guiding cotton, and round bar. The winding robot 451 clamps the oil-guiding cotton and pushes it into the product mounting position 110. The product mounting position 110 is set with a cylindrical structure, so that the oil-guiding cotton can wind the heating wire and round bar into it during the pushing process, realizing the cotton winding work.

[0066] The outer casing feeding mechanism 6 includes an outer casing conveyor line, a film-tearing mechanism, and an outer casing picking assembly 65. The outer casing conveyor line is used to convey the film with the outer casing attached. The film-tearing mechanism is located at the end of the outer casing conveyor line and is used to tear off the film attached to the surface of the outer casing. The outer casing picking assembly 65 is used to clamp the outer casing after the film has been torn off and assemble it onto the outer periphery of the oil-wicking cotton in the product mounting position 110. In this embodiment, the bottom of the outer casing is provided with an opening, so even if there is excess oil-wicking cotton extending into the product mounting position 110, it will not affect the assembly work.

[0067] The housing loading mechanism 6 also includes a housing picking assembly 65, which can move back and forth between the third rotary clamping assembly 62 and the fixture 11 to assemble the housing held by the third rotary clamping assembly 62 to the product mounting position 110 on the fixture 11.

[0068] The housing conveying line includes a housing conveying platform 60 and a film driving device 66. A fourth through hole 602 is provided on the conveying platform. The output shaft of the film driving device 66 is connected to a third moving block 660. The third moving block 660 has a triangular structure, and its top is restricted in the fourth through hole 602. The film driving device 66 can act on the third moving block 660 to push the film placed on the conveying platform to move.

[0069] Two fourth through holes 602 are provided. The bottom of the third moving block 660, which is confined within the two fourth through holes 602, is connected to the first connecting plate. The film driving device 66 is connected to the first connecting plate and is used to drive the first connecting plate to move. Pressure blocks 601 are provided on both sides of the surface of the conveying platform. There is a gap between the pressure blocks 601 and the conveying platform for the film to pass through. By providing pressure blocks 601, the two sides of the film can be pressed to prevent it from curling.

[0070] A cutter assembly 631 is provided at the end of the outer casing conveyor line. The cutter assembly 631 includes cutters 631 disposed on both sides of the film and a cutter drive device 63. The cutter drive device 63 is used to drive the cutters 631 to move up and down to cut the film. The output shaft of the cutter drive device 63 is connected to the bottom of the cutter 631 through a connecting rod 630.

[0071] This creates a lever relationship between the output shaft of the cutter drive device 63 and the cutter 631. When the cutter drive device 63 extends, the cutter 631 is driven upward by the connecting rod 630. When the cutter drive device 63 retracts, the cutter 631 is driven downward by the connecting rod 630. The time interval between the extension and retraction of the cutter drive device 63 is equal to the working interval of the film drive device 66. That is, while the film drive device 66 is conveying the film with the outer shell attached forward one station, the cutter drive device 63 extends and retracts, driving the cutter 631 to cut both sides of the conveyed film. Then, the third rotary clamping assembly 62 clamps the outer shell and rotates it to peel the outer shell off the film.

[0072] The film-tearing mechanism is located on the outside of the cutter 631 assembly. The film-tearing mechanism includes a film-tearing unit 64 and a film-tearing drive device 642. The film-tearing unit 64 has a U-shaped opening at one end, with protruding structures 641 at both ends of the U-shaped opening facing the outer casing conveyor line. The protruding structures 641 have an opening in the middle for the film to pass through. The film-tearing drive device 642 drives the film-tearing unit 64 to swing, thus tearing the film. The film-tearing unit 64 has a waist-shaped through-hole 640 in the middle. The output shaft of the film-tearing drive device 642 is confined within the waist-shaped through-hole 640. When the film-tearing drive device 642 operates, the film-tearing unit 64 swings eccentrically relative to the output shaft of the film-tearing drive device 642. Simultaneously, since the film passes through the opening in the middle of the protruding structure 641, and the film has already been cut by the cutter 631 assembly, when the film-tearing unit 64 swings, the protruding structure 641 can cause the cut edge of the film to shake, thus tearing the film.

[0080] The present invention also provides a method for processing an atomizing core, using the atomizing core assembly equipment described above, comprising the following steps:

[0081] Step 1: Feeding the oil-guiding cotton. The oil-guiding cotton is fed through the unwinding assembly, the winding assembly and the oil-guiding cotton conveying platform 22 in the oil-guiding cotton feeding mechanism 2. The oil-guiding cotton picking assembly 29 picks up the oil-guiding cotton and puts it into the initial placement position 112 of the fixture 11.

[0082] Step 2: Heating wire feeding. The oil-guiding cotton is fed through the heating wire conveying track, displacement component and cutting component in the heating wire feeding mechanism 3. The heating wire picking component 36 picks up the heating wire and puts it into the initial placement position 112 of the fixture 11.

[0083] Step 3: Round bar feeding and cotton winding. The round bars are conveyed by the first hopper 40 and the feeding platform 41 in the round bar feeding mechanism 4. The round bar picking assembly picks up the round bars and puts them into the initial placement position 112 of the fixture 11. Then, the cotton winding assembly pushes the oil-guiding cotton from the initial placement position 112 to the product installation position 110. During the pushing process, the oil-guiding cotton can wind the heating wire and the round bar into it to realize the cotton winding work.

[0084] Step 4: Shell loading. The shell is conveyed through the shell conveyor line and film tearing mechanism in the shell loading mechanism 6. The shell is picked up by the shell picking assembly 65 and placed into the product mounting position 110 of the fixture 11. The notch on the shell is aligned with the part of the oil-guiding cotton that extends out of the product mounting position 110 and inserted. It is then fitted onto the outer periphery of the oil-guiding cotton, heating wire and round rod that have undergone the cotton rolling process.

[0085] Step 5: Gear plug feeding. The gear plug is conveyed by the feeding device in the gear plug feeding mechanism 7. The gear plug picking assembly 73 cooperates with the gear plug positioning assembly 76 to assemble the gear plug into the housing along the fifth through hole 7631 in the positioning block 7630.

[0086] Step Six: Unloading. The sixth robotic arm is driven by the sixth robotic arm drive device to clamp the assembled product and move it to the unloading trough for unloading.

[0087] Example 2:

[0088] Reference Figure 15 The difference between this embodiment and embodiment 1 is that there is no notch at the bottom of the outer shell. Therefore, a cotton-cutting mechanism 5 is required to trim the part of the oil-guiding cotton that extends out of the product mounting position 110, so that the outer shell can be fitted onto the outer periphery of the oil-guiding cotton. The cotton-cutting mechanism 5 is located between the round bar feeding mechanism 4 and the outer shell feeding mechanism 6.

[0089] The cotton-cutting mechanism 5 is located between the heating wire feeding mechanism 3 and the round bar feeding mechanism 4, and is used to trim the two ends of the oil-guiding cotton. The cotton-cutting mechanism 5 includes a first cotton-cutting bracket 50 and a first lifting cylinder 54 located on the top of the first cotton-cutting bracket 50. The output shaft of the first lifting cylinder 54 is connected to two first cotton-cutting cylinders 51 through a lifting plate 540. The output shafts of the two first cotton-cutting cylinders 51 are connected to a scissor control plate. The scissor control plate is provided with two rows of cams 52. The bottom of the lifting plate 540 is connected to a first scissor 53. The operating handle of the first scissor 53 is located between the two rows of positioning cams 52. The first lifting cylinder 54 controls the vertical height of the first scissor 53, and the first cotton-cutting cylinders 51 control the vertical height of the cams 52, further controlling the opening and closing of the first scissor 53 to realize the cutting work.

[0090] After the cotton shearing mechanism 5 trims the oil-guiding cotton, it rotates with the fixture 11 to the round bar feeding mechanism 4 for cotton winding. After that, it can be directly fitted inside the outer shell.

[0091] This embodiment also provides a method for processing an atomizing core, using the atomizing core assembly equipment as described in this embodiment, including the following steps:

[0092] Step 1: Feeding the oil-guiding cotton. The oil-guiding cotton is fed through the unwinding assembly, the winding assembly and the oil-guiding cotton conveying platform 22 in the oil-guiding cotton feeding mechanism 2. The oil-guiding cotton picking assembly 29 picks up the oil-guiding cotton and puts it into the initial placement position 112 of the fixture 11.

[0093] Step 2: Heating wire feeding. The oil-guiding cotton is fed through the heating wire conveying track, displacement component and cutting component in the heating wire feeding mechanism 3. The heating wire picking component 36 picks up the heating wire and puts it into the initial placement position 112 of the fixture 11.

[0094] Before performing step three, cotton cutting is required. The excess oil-guiding cotton that has been rolled will extend to the outside of the product mounting position 110 and be cut by the cotton cutting mechanism 5.

[0095] Step 3: Round bar feeding and cotton winding. The round bars are conveyed by the first hopper 40 and the feeding platform 41 in the round bar feeding mechanism 4. The round bar picking assembly picks up the round bars and puts them into the initial placement position 112 of the fixture 11. Then, the cotton winding assembly pushes the oil-guiding cotton from the initial placement position 112 to the product installation position 110. During the pushing process, the oil-guiding cotton can wind the heating wire and the round bar into it to realize the cotton winding work.

[0096] Step 4: Shell loading. The shell is conveyed through the shell conveyor line and film tearing mechanism in the shell loading mechanism 6. The shell is picked up by the shell picking assembly 65 and placed into the product mounting position 110 of the fixture 11. The notch on the shell is aligned with the part of the oil-guiding cotton that extends out of the product mounting position 110 and inserted. It is then fitted onto the outer periphery of the oil-guiding cotton, heating wire and round rod that have undergone the cotton rolling process.

[0097] Step 5: Gear plug feeding. The gear plug is conveyed by the feeding device in the gear plug feeding mechanism 7. The gear plug picking assembly 73 cooperates with the gear plug positioning assembly 76 to assemble the gear plug into the housing along the fifth through hole 7631 in the positioning block 7630.

[0098] Step Six: Unloading. The sixth robotic arm is driven by the sixth robotic arm drive device to clamp the assembled product and move it to the unloading trough for unloading.

[0099] Example 3:

[0100] Reference Figures 16 to 17 The difference between this embodiment and the second embodiment is that the cotton-cutting mechanism 5 is located between the round bar feeding mechanism 4 and the outer shell feeding mechanism 6, and is used to trim the oil-guiding cotton after the cotton rolling process. In another specific embodiment, two layers of oil-guiding cotton need to be set in the outer shell. Therefore, two rows of initial placement positions 112 need to be set on the fixture 11. One row of initial placement positions 112 is used to place the first oil-guiding cotton, and the other row of initial placement positions 112 is used to place the second oil-guiding cotton. Both oil-guiding cotton can be cut by the cotton-cutting mechanism 5 provided in this embodiment after the cotton rolling process.

[0101] The cotton shearing mechanism 5 includes a second moving module 501. Before the fixture 11 rotates with the turntable 10 to the cotton shearing mechanism 5 in this embodiment, the oil-guiding cotton has already been rolled. The product mounting position 110 of the fixture 11 is provided with a shearing groove 111. The excess part of the oil-guiding cotton extends to the outside of the product mounting position 110 through the shearing groove 111. The shearing component is set relative to the shearing groove 111. A shearing unit is provided on the second moving module 501. The shearing unit can reciprocate along the second moving module 501. The second moving module 501 drives the shearing unit to approach the shearing groove 111 of the fixture 11 and perform shearing work. The shearing unit includes a second scissors 5021, a second cotton shearing cylinder 5020, and a scissors drive block 5023. The output shaft of the second cotton shearing cylinder 5020 is connected to the scissors drive block 5023 through an eccentric wheel 5022. The scissors drive block 5023 is set at one end of the operating handle of the second scissors 5021. The scissor drive block 5023 is configured with a W-shaped structure, and its two inwardly extending parts are positioned relative to the two operating handles of the second scissors 5021.

[0102] Because an eccentric wheel 5022 is provided between the second cotton-cutting cylinder 5020 and the scissor drive block 5023, each rotation of the second cotton-cutting cylinder 5020 can drive the scissor drive block 5023 to move back and forth once in the horizontal direction under the action of the eccentric wheel 5022. The two inwardly extending parts of the scissor drive block 5023 are positioned relative to the two operating handles of the second scissors 5021. When the scissor drive block 5023 moves forward, it can open the two operating handles of the second scissors 5021, and the two blades of the second scissors 5021 will open accordingly. When the scissor drive block 5023 moves backward, the two operating handles of the second scissors 5021 return to their original positions, and the two blades of the second scissors 5021 close. The opening and closing of the blades can be driven by the second cotton-cutting cylinder 5020 to realize the cutting work.

[0103] The cotton shearing mechanism 5 in this embodiment further includes a cotton shearing positioning component. This component includes a first positioning structure 503 disposed on the upper side of the fixture 11 and a second positioning structure 504 disposed on the lower side of the fixture 11. The second positioning structure 504 is connected to the lower surface of the upper sealing plate. The first positioning structure 503 includes a first positioning drive device 5030 and a pressure plate 5031 connected to the output shaft of the first positioning drive device 5030. The bottom of the pressure plate 5031 has a fourth groove, which is an inverted funnel-shaped structure. The round bar may sway during its rotation with the fixture 11. The inverted funnel-shaped structure guides the round bar, ensuring that the first positioning drive device 5030 can smoothly press the pressure plate 5031 downwards.

[0104] The second positioning structure 504 includes a mounting block 5040 fixed to the lower surface of the upper sealing plate. The mounting block 5040 is provided with a positioning gripper cylinder 5041, a second positioning drive device 5042 disposed below the positioning gripper cylinder 5041, and a support rod 5043 connected to the output shaft of the second positioning drive device 5042. The support rod 5043 is disposed relative to the product mounting position 110 of the fixture 11.

[0105] The working process of the positioning component is as follows: First, the first positioning drive device 5030 drives the pressure plate 5031 to press the round bar in the product downward. When it is pressed to the gripper cylinder, the gripper cylinder is controlled to open and hold the round bar and then pull it down. The height of the top of the support rod 5043 is adjusted by the second positioning drive device 5042. When the gripper cylinder pulls the round bar to abut against the support rod 5043, the positioning work is completed.

[0106] This embodiment also provides a method for processing an atomizing core, using the atomizing core assembly equipment as described in this embodiment, including the following steps:

[0107] Step 1: Feeding the oil-guiding cotton.

[0108] Step 2: Heating wire feeding. The oil-guiding cotton is fed through the heating wire conveying track, displacement component and cutting component in the heating wire feeding mechanism 3. The heating wire picking component 36 picks up the heating wire and puts it into the initial placement position 112 of the fixture 11.

[0109] Step 3: Round bar feeding and cotton winding. The round bars are conveyed by the first hopper 40 and the feeding platform 41 in the round bar feeding mechanism 4. The round bar picking assembly picks up the round bars and puts them into the initial placement position 112 of the fixture 11. Then, the cotton winding assembly pushes the oil-guiding cotton from the initial placement position 112 to the product installation position 110. During the pushing process, the oil-guiding cotton can wind the heating wire and the round bar into it to realize the cotton winding work.

[0110] Before performing step four, cotton cutting is required. The excess oil-guiding cotton that has been rolled will extend to the outside of the product mounting position 110 and be cut by the cotton cutting mechanism 5.

[0111] Step 4: Shell loading. The shell is conveyed through the shell conveyor line and film tearing mechanism in the shell loading mechanism 6. The shell is picked up by the shell picking assembly 65 and placed into the product mounting position 110 of the fixture 11. The notch on the shell is aligned with the part of the oil-guiding cotton that extends out of the product mounting position 110 and inserted. It is then fitted onto the outer periphery of the oil-guiding cotton, heating wire and round rod that have undergone the cotton rolling process.

[0112] Step 5: Gear plug feeding. The gear plug is conveyed by the feeding device in the gear plug feeding mechanism 7. The gear plug picking assembly 73 cooperates with the gear plug positioning assembly 76 to assemble the gear plug into the housing along the fifth through hole 7631 in the positioning block 7630.
