Description

Technical Field

[0001] The invention relates to the technical field of atomizer production equipment, and in particular to a multi-station atomizer tube rotary assembly device. Background Art

[0002] An e-cigarette is a device powered by a rechargeable lithium polymer battery. It heats the e-liquid in a tank to produce vapor for the user to inhale, creating a vapor that resembles a cigarette in appearance, smoke, taste, and feel. The e-cigarette atomizer is a separate component of the e-cigarette, housing and heating the e-liquid. When powered, the heating wire inside the atomizer generates heat, heating the e-liquid in the atomizer chamber and atomizing it.

[0003] An electronic cigarette generally consists of a tubular main body, a microphone, oil-absorbing cotton cloth, a heating wire, a fixing sleeve and a battery. The oil-absorbing cotton cloth needs to be rolled into a tubular structure, and the heating wire is wrapped in the oil-absorbing cotton cloth and then inserted into the fixing sleeve to fix the oil-absorbing cotton cloth and the heating wire.

[0004] The traditional production method is to roll the oil-absorbing cotton cloth into a tube, then wrap the electric heating wire mesh inside the oil-absorbing cloth and install it into a fixed sleeve. This is mainly done manually and is labor-intensive. Currently, the industry uses automated equipment for assembly. After the electric heating wire mesh and cotton cloth are rolled into a tube cone, the electric heating wire mesh is wrapped in cotton cloth and then clamped into a fixed sleeve.

[0005] For example, the Chinese patent document with the announcement number CN216906868U discloses an automated device for feeding cotton into the tube of an electronic cigarette heating sheet, which discloses a schematic diagram of the processing flow of a component contained in the electronic cigarette: taking a cotton strip, then taking a heating sheet, and stacking the heating sheet on the cotton strip according to a predetermined position; then pressing the auxiliary rod, the heating sheet, and the cotton strip into an assembly, pushing the assembly into the open tube, and cutting off the excess cotton strip extending out of the open tube. At this point, these parts are assembled into a finished product. It includes: a sliver feeding assembly, a heating plate feeding assembly, an auxiliary rod feeding and pressing assembly, a clamping mechanism, an open tube feeding assembly, a pushing tube assembly, and a shearing assembly; the sliver feeding assembly is used to convey the slivers to the clamping mechanism; the heating plate feeding component is used to convey the heating plate to the upper end surface of the sliver clamped and fixed by the clamping mechanism; the auxiliary rod feeding and pressing assembly is used to convey the auxiliary rod to the pressing station, and press the auxiliary rod and the heating plate and sliver clamped and fixed by the clamping mechanism into an assembly; the open tube feeding assembly is used to convey the open tube to the clamping mechanism; the cotton feeding assembly is used to push the assembly into the open tube; the shearing assembly is used to cut off the excess slivers extending out of the open tube.

[0006] Since the above-mentioned tampon is inserted into the open tube, and then the excess section of the tampon that does not cover the auxiliary rod is cut off, the above-mentioned open tube must be open so that the tampon can be inserted into the open tube and the excess section can leak out from the opening. However, in actual improvements, the so-called open tube is not necessarily open, but the excess section of the tampon is cut off before being inserted into the tube, so the original open tube is defined here as a metal tube. For the assembly of tampon, heating plate, auxiliary rod and metal tube, the existing assembly carrier structure is complex, which restricts production efficiency and is costly. Summary of the Invention

[0007] In view of the above technical problems in the prior art, the present invention provides a multi-station atomizing tube rotating assembly device.

[0014] As a further optional solution, the sliding direction of the two tube clamping sliders is horizontal, and a loosening inclined surface is provided on the top of the tube clamping slider. The external force exerting downward pressure on the loosening inclined surface can overcome the force of the tube clamping spring and drive the two tube clamping sliders to move in opposite directions.

[0015] As a further optional solution, a shaping slope is provided on the top of the side wall where the two cotton-supporting protrusions are adjacent to each other.

[0016] As a further optional solution, a magnet is provided on the top of the core stacking seat, which is used to magnetically attract and position the guide wire of the heating plate.

[0017] As a further optional solution, the core push rod is in a non-integral ring shape, with an inner diameter larger than the diameter of the auxiliary rod and an outer diameter smaller than the inner diameters of the transfer hole and the metal tube.

[0018] As a further optional solution, the transfer hole includes an introduction cone section and a cotton hoop straight section in sequence toward the pipe clamp seat, and the opening of the introduction cone section faces the core push rod.

[0025] As a further optional solution, the core pushing slide is fixed with a connecting slide, the connecting slide is connected with a connecting slide rail, and the core pushing rod is fixedly connected to the connecting slide rail.

[0026] Beneficial effects of the present invention:

[0027] The present invention provides a multi-station atomizing tube rotary assembly device. When in use, under the step rotation of the rotating table, each assembly carrier on the rotating table passes through different stations in sequence, and at different stations respectively realizes: clamping multiple metal tubes on the tube clamping seat, placing the flat cotton strips on the core stacking groove of the core stacking seat, relying on the cotton supporting part to support the two ends of the cotton strips and the cotton supporting protrusion to support the middle of the cotton strips to prevent the cotton strips from sinking; then placing the heating plate in the middle of the cotton strips, corresponding to the gap between the two cotton supporting protrusions; then horizontally inserting the auxiliary rod into the shaping groove. During this process, the auxiliary rod presses the cotton strips and the heating plate to deform and insert into the shaping groove. At this time, the cotton strips and the heating plate are deformed to wrap around the auxiliary rod, and the excess section of the cotton strip that does not wrap around the auxiliary rod extends into the core stacking groove, that is, between the two cotton supporting protrusions. The root of the excess section of the cotton strip clamped by external force is transferred to the transfer hole of the transfer seat, and the external force cuts off the excess section of the cotton strip.

[0048] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0049] A multi-station atomizing tube rotating assembly device of this embodiment, such as Figure 1As shown, the system comprises a turntable 3, a station switching drive module 31 for driving the turntable 3 to rotate stepwise to different stations, and a plurality of assembly carriers 4 arranged around the top surface of the turntable 3. Each assembly carrier 4 is arranged along the radial direction of the turntable 3 and is arranged near the periphery of the top surface of the turntable 3. The station switching drive module 31 includes a station switching drive motor 311 and a reducer 312 mounted on the output shaft of the station switching drive motor 311. The output shaft of the reducer 312 is fixedly connected to the rotation center of the turntable 3.

[0050] like Figure 2 As shown, each assembly carrier 4 includes a carrier base 41, and a tube clamping module 42, an inner core assembly module 43, a transfer module 44 and a core pushing module 45 installed on the carrier base 41. The following describes each module and their mutual cooperation relationship.

[0051] Combine Figure 3 and Figure 4 As shown, the pipe clamping module 42 includes a plurality of pipe clamping seats 421 for clamping metal pipes a, and the figure shows the state of six metal pipes a being clamped. The carrier base 41 is provided with a pipe insertion slide 411, and the pipe insertion slide 411 is adapted to be equipped with a pipe clamping slide 422. The pipe clamping slide 422 is provided with a pipe clamping base 423. A plurality of pipe clamping seats 421 are fixed on the pipe clamping base 423 in parallel along a straight line. The pipe clamping seats 421 can be driven by external force to move toward the transfer module 44. The pipe clamping base 423 is connected to a first return spring 424 to keep the pipe clamping base 423 away from the transfer module 44, that is, after the external force is released, the first return spring 424 can automatically reset the pipe clamping module 42 to a position away from the transfer module 44.

[0052] In this embodiment, each pipe clamping seat 421 includes a pipe clamping fixing block 4211, a pipe clamping positioning block 4212, and two pipe clamping sliders 4214. The pipe clamping fixing block 4211 is locked to the pipe clamping base 423. The pipe clamping positioning block 4212 is fixed to the pipe clamping fixing block 4211 and is provided with a pipe clamping groove adapted to the outer diameter of the clamped metal pipe a. The two pipe clamping sliders 4214 are slidably mounted on the pipe clamping fixing block 4211, capable of sliding toward or away from each other. The pipe clamping fixing block 4211 is provided with a pipe clamping spring 4213 that applies force to the pipe clamping sliders 4214, so that the two pipe clamping sliders 4214 elastically clamp the metal pipe a together. Specifically, the two pipe clamping sliders 4214 slide in a horizontal direction, and the tops of the pipe clamping sliders 4214 are provided with a loosening inclined surface 4215. External force exerting downward pressure on the loosening inclined surface 4215 can overcome the force of the pipe clamping spring 4213 and drive the two pipe clamping sliders 4214 to move away from each other. The clamping surface of the tube clamping slider 4214 is an arc surface adapted to the outer wall of the metal tube a, which makes the clamping more stable.

[0053] Combine Figure 5 、 Figure 6 and Figure 7 As shown, the inner core assembly module 43 is fixed to the carrier base 41 and includes a core stacking seat 431. The core stacking seat 431 is arranged side by side with the clamping tube base 423, but staggered in height. The core stacking seat 431 is provided with multiple core stacking slots 432. Cotton support portions 433 are provided at both ends of the core stacking slots 432 for supporting the horizontally placed tampon b and the heating plate c placed on the tampon b. The core stacking slots 432 are provided with two cotton support protrusions 434 for supporting the middle portion of the horizontally placed tampon b. The two cotton support protrusions 434 are spaced apart along the length of the tampon b. At the bottom of the core stacking slots 432, corresponding to the position between the two cotton support protrusions 434, a shaping slot 436 with an upward-facing arc-shaped opening is provided. The shaping slot 436 extends horizontally through the core stacking seat 431 to allow the auxiliary rod d to be inserted downward. When in use, place the flat tampon b on the core stacking groove 432 of the core stacking seat 431, rely on the cotton supporting portion 433 to support both ends of the tampon b and the cotton supporting protrusion 434 to support the middle of the tampon b to prevent the tampon b from sinking; then place the heating plate c in the middle of the tampon b, corresponding to the gap between the two cotton supporting protrusions 434, as shown in FIG. Figure 7 The state is shown in the enlarged figure on the left. Then the auxiliary rod d is inserted horizontally into the shaping groove 436. During this process, the auxiliary rod d presses the cotton strip b and the heating plate c to deform and insert into the shaping groove 436. At this time, the part of the cotton strip b and the heating plate c are deformed to wrap around the auxiliary rod d, and the redundant section of the cotton strip b that does not wrap around the auxiliary rod d extends into the core stacking groove 432, that is, between the two cotton supporting protrusions 434, as shown in FIG. Figure 7 The enlarged image on the middle right shows the pre-assembly of the sliver b, heating element c, and auxiliary rod d at the core stacking base 431. This pre-assembled assembly is defined as a prefabricated core. The cotton-supporting projection 434 is flat, with a clearance between its two side walls and the inner wall of the core stacking groove 432. This clearance allows external clamping arms to fit in and grip the base of the excess section of the sliver b, transferring the prefabricated core to the transfer module 44. This prevents the sliver b from becoming fluffy while enveloping the auxiliary rod d during the transfer process.

[0054] Specifically, a shaping slope 435 is provided on the top of the side wall adjacent to the two cotton-supporting protrusions 434 to facilitate the insertion of the auxiliary rod d from top to bottom and to support the excess segment of the cotton strip b. Specifically, a magnet 437 is provided on the top of the core stacking seat 431, which is used to magnetically position the guide wire of the heating plate c to prevent deformation of the guide wire of the heating plate c.

[0055] Combine Figure 8 and Figure 9As shown, the transfer module 44 includes a transfer base 441 fixed to the carrier base 41 and a plurality of transfer seats 442 installed in parallel on the transfer base 441. The plurality of transfer seats 442 are aligned one by one with the plurality of clamping tube seats 421. Each transfer seat 442 is provided with a transfer hole 443 with a transverse axis. When in use, the prefabricated core in the inner core assembly module is inserted into the transfer hole 443. A cotton cutting auxiliary plane 444 is provided on the top of the transfer seat 442, so that the top of the transfer hole 443 is open, and the excess segments of the cotton strip b pass through this opening for subsequent cutting. Figure 8 The redundant segments of the slivers b of the prefabricated cores of the three transfer seats 442 on the left have not been cut off, while the redundant segments of the slivers b of the prefabricated cores of the three transfer seats 442 on the right have been cut off. It can be seen that the cut surface of the slivers b is basically flush with the cotton cutting auxiliary plane 444, and the slivers b left at this time are roughly cylindrical. It can be seen that the radial cross-section of the inner wall of the transfer hole 443 is not a full circle. It is preferred that its circumferential span is greater than 180° to facilitate guiding the slivers b to retract 360° to wrap around the auxiliary rod d, and the redundant segments are roughly V-shaped for subsequent cutting. The transfer base 441 and the clamping tube base 423 are arranged side by side. The clamping tube seat 421 and the transfer seat 442 can be close to or away from each other so that the metal tube a on the clamping tube seat 421 can be connected to the transfer hole 443.

[0056] Combine Figure 10 As shown, the core push module 45 includes a plurality of core push rods 451 aligned one-to-one with the transfer holes 443 and a core push slide 452 adapted to the tube insertion slide 411. The core push slide 452 and the tube clamping slide 422 are respectively located on either side of the transfer base 441. The core push slide 452 is fixed with a connecting slide 453, which is connected to a connecting slide 454. The core push rods 451 are fixedly connected to the connecting slide 454, so that the core push rods 451 can be slidably mounted on the core push slide 452. The core push slide 452 is connected to a second return spring 455 to keep the core push slide 452 away from the transfer base 441. Similarly, the core push rod 451 is connected to a third return spring 456 to keep the core push rod 451 away from the transfer base 442.

[0057] During use, an external force first drives the core push slide 452 and the core push rod 451 thereon toward the transfer seat 442. The core push rod 451 then slides relative to the core push slide 452, causing multiple core push rods 451 to move toward the transfer seat 442 and be inserted into multiple transfer holes 443. The core push rod 451 pushes the auxiliary rod d and the heating plate c and cotton strip b wrapped thereon against the end of the cotton strip b into the metal tube a, thus completing the assembly. After the external force pushing the core push slide 452 toward the transfer is released, the second return spring 455 drives the core push slide 452 to return to its initial position; after the external force pushing the core push rod 451 to insert into the transfer hole 443 is released, the third return spring 456 drives the core push rod 451 to return to its initial position. In this embodiment, the core pusher 451 is in the form of a non-integer ring, with the figure showing a 180° ring. Its inner diameter is larger than the diameter of the auxiliary rod d, and its outer diameter is smaller than the inner diameters of the transfer hole 443 and the metal tube a, facilitating insertion into the transfer hole 443 and the metal tube a, where the preformed core is placed. In this embodiment, the transfer hole 443 comprises a tapered guide section 4431 and a straight cotton hooping section 4432, which extend in sequence toward the clamping tube seat 421. The opening of the tapered guide section 4431 faces the core pusher 451, serving as a guide for inserting the preformed core. The straight cotton hooping section 4432 securely holds the cylindrical cotton sliver b, preventing it from becoming fluffy and deforming.
