Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, specifically to a core rod feeding mechanism. Background Technology

[0002] Electronic cigarettes are electronic products that mimic traditional cigarettes. They mainly consist of e-liquid, an atomizer coil, a power source, and a filter. They produce an aerosol with a specific aroma through heating and vaporization for smokers to use. The atomizer coil is the crucial component in an electronic cigarette that generates vapor by heating the e-liquid. The basic structure of the atomizer coil includes a coil rod, a heating element, an inner wick, an outer wick, hardware, and a shell. During assembly, the heating element, inner wick, and outer wick are placed sequentially on a fixture. The coil rod is then placed to one side of the heating element. By pushing the coil rod, the heating element, inner wick, and outer wick are wrapped around the outer circumference of the coil rod. The wrapped coil rod, heating element, inner wick, and outer wick are then assembled into the hardware to form a semi-finished atomizer coil. One end of the outer wick is then pulled out to a certain length and wrapped around the outer circumference of the hardware. Finally, the shell is fitted over the outer wick to form the atomizer coil. The main function of the coil rod is to support the heating element and maintain its shape.

[0003] The atomizing principle of the atomizing core is that when the user activates the atomizing core by inhaling or triggering it through a mechanical structure, a potential difference is formed at both ends of the heating core, and a current is generated inside, producing Joule heat. Because the heating core is in contact with the cotton tube that has absorbed e-liquid, the heating effect of the heating core atomizes the e-liquid into smoke.

[0004] However, existing coil loading is done from above the fixture. Since the heating element pins on the fixture extend upwards, the coil can easily touch the heating element pins when loaded from above, causing the heating element pins to deform or be damaged, thus affecting the quality of the atomizing core.

Detailed Implementation

[0034] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. 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 utility model can be combined interactively without contradicting each other.

[0035] Reference Figures 1 to 6 An example of this utility model provides a mandrel feeding mechanism, which includes a hopper 100, a pushing component 200, an air blowing component 300, a flipping component 400, and a transplanting component 500.

[0036] The hopper 100 has a discharge port at its bottom. The pushing assembly 200 includes a base plate 210, a receiving block 220, and a first driving member 230. The first driving member 230 is mounted on the base plate 210 and is used to drive the receiving block 220 to move horizontally. The receiving block 220 is located directly below the hopper 100. The top of the receiving block 220 is provided with a receiving groove 221 for receiving the mandrel.

[0037] Positionally, the air blowing assembly 300 and the flipping assembly 400 are located on both sides of the receiving block 220. The air blowing assembly 300 is used to blow the mandrel along the length direction to move it into the flipping assembly 400.

[0038] Furthermore, the flipping assembly 400 is used to flip the mandrel, including a flipping seat 410 and a second drive member 420 for driving the flipping seat 410 to flip. The flipping seat 410 is provided with a receiving hole 411 for receiving the mandrel.

[0039] Furthermore, the transplanting assembly 500 is used to transplant the flipped mandrel onto the fixture, and includes a transplanting robot 510, a first gripper 520, a translation module 530, and a lifting module 540. The transplanting robot 510 is used to grip the flipped mandrel onto the first gripper 520, the first gripper 520 is used to hold the mandrel, the translation module 530 is used to drive the first gripper 520 to translate, and the lifting module 540 is used to drive the first gripper 520 to lift.

[0040] During operation, multiple mandrels are placed horizontally in the hopper 100. The mandrels fall from the discharge port into the receiving groove 221 on the receiving block 220. The first driving member 230 drives the receiving block 220 to move horizontally, causing the mandrels on the receiving groove 221 to move to the corresponding position on the air blowing assembly 300. At this time, the top of the receiving block 220 blocks the discharge port, preventing other mandrels in the hopper 100 from being blocked by the receiving block 220. Then, the second driving member 420 drives the tilting seat 410 to tilt, so that the receiving hole 411 on the tilting seat 410 aligns with one end of the receiving groove 221. Then, the air blowing assembly 300 blows air, causing the mandrels in the receiving groove 221 to move. The atomizing core is blown into the receiving hole 411. Then, the second driving member 420 drives the flipping seat 410 to flip, which in turn drives the core rod to flip from the horizontal to the vertical position. Next, the transfer robot 510 grabs the top of the core rod and transfers it into the first gripper 520. The first gripper 520 clamps the bottom of the core rod. Then, the translation module 530 drives the first gripper 520 and the core rod to translate together to the bottom of the fixture. Finally, the lifting module 540 drives the first gripper 520 and the core rod to rise together, so that the core rod moves into the fixture. Thus, the core rod can be fed from the bottom of the fixture, avoiding collision between the core rod and the pin of the heating core, and improving the quality of the atomizing core.

[0041] Specifically, the first driving component 230 is a telescopic cylinder, and the second driving component 420 is a rotary cylinder.

[0042] In some preferred embodiments, the air blowing assembly 300 includes a first support 310, a second support 320, and an air blowing nozzle 330 disposed on the first support 310. The first support 310 and the second support 320 are respectively located on both sides of the receiving block 220. The flipping seat 410 is located on one side of the second support 320. The second support 320 is provided with a first sliding groove 321. The air blowing nozzle 330 corresponds to the first sliding groove 321. The bottom wall of the receiving groove 221 is flush with the bottom wall of the first sliding groove 321.

[0043] Understandably, when the receiving block 220 moves the mandrel on the receiving groove 221 to the position corresponding to the air nozzle 330, the air nozzle 330 blows air, blowing the mandrel on the receiving groove 221 along the first sliding groove 321 into the receiving hole 411 of the flipping block. The first sliding groove 321 can guide the mandrel, thereby achieving accurate delivery of the mandrel and improving the stability of the mandrel feeding process.

[0044] In some preferred embodiments, the top of the first bracket 310 and the second bracket 320 is connected to a limiting plate 340. When the receiving block 220 moves the mandrel on the receiving groove 221 to the position corresponding to the blowing nozzle 330, the receiving block 220 is located directly below the limiting plate 340. The limiting plate 340 limits the mandrel in the receiving groove 221, thereby preventing the mandrel from flying out when the blowing nozzle 330 blows it.

[0045] Furthermore, a photoelectric sensor 350 is provided on the limiting plate 340. The photoelectric sensor 350 is used to sense whether the core rod is present in the receiving groove 221. If the core rod is detected in the receiving groove 221, the next process stops working, the photoelectric sensor 350 transmits a signal to the equipment, and the equipment issues an alarm signal, so that the operator can check the abnormality in time. If the core rod is not detected in the receiving groove 221, the next process works normally.

[0046] In some preferred embodiments, a first linear guide rail 240 is provided between the receiving block 220 and the base plate 210. The first linear guide rail 240 can provide guidance for the receiving block 220, thereby improving the stability of the receiving block 220 when it moves and ensuring that the mandrel after translation corresponds to the air nozzle 330.

[0047] In some preferred embodiments, the translation module 530 includes a first mounting plate 531, a servo motor 532 mounted on the first mounting plate 531, a first bearing seat 533, a second bearing seat 534, a lead screw 535, a nut 536, and a moving block 537. The two ends of the lead screw 535 are rotatably connected to the first bearing seat 533 and the second bearing seat 534, respectively. The servo motor 532 is used to drive the lead screw 535 to rotate. The nut 536 is threadedly connected to the lead screw 535 and fixedly connected to the moving block 537. The lifting module 540 is mounted on the moving block 537, and the first gripper 520 is mounted on the lifting module 540.

[0048] It is understandable that by driving the lead screw 535 to rotate through the servo motor 532, the lead screw 535 drives the nut 536 and the moving block 537 to move, and the moving block 537 drives the lifting module 540 and the first gripper 520 to move together, thereby accurately controlling the translation distance of the mandrel and ensuring that the mandrel is aligned with the fixture.

[0049] Furthermore, a second linear guide rail 538 is provided between the movable block 537 and the first mounting plate 531. The length direction of the second linear guide rail 538 extends along the length direction of the lead screw 535. The second linear guide rail 538 can provide guidance for the movable block 537, so that the movable block 537 can translate along the length direction of the second linear guide rail 538, thereby improving the stability during mandrel transplantation.

[0050] In some preferred embodiments, the lifting module 540 includes a second mounting plate 541, a reduction motor 542 disposed on the second mounting plate 541, a cam 543 disposed at the output end of the reduction motor 542, a follower wheel 544 connected to the cam 543, a lifting plate 545 connected to the follower wheel 544, and a first gripper 520 disposed on the lifting plate 545.

[0051] Furthermore, the lifting plate 545 is provided with a second slide groove 546, which is arranged horizontally. The follower wheel 544 is movably connected in the second slide groove 546. A third linear guide rail 547 is provided between the lifting plate 545 and the second mounting plate 541, and the third linear guide rail 547 is arranged vertically.

[0052] Understandably, the geared motor 542 drives the cam 543 to rotate, the cam 543 drives the follower wheel 544 to roll along the second slide groove 546, and the follower wheel 544 drives the lifting plate 545 to slide along the length direction of the third linear guide rail 547, thereby enabling the precise lifting and lowering of the mandrel.

[0053] In some preferred embodiments, the first gripper 520 includes a finger cylinder 521 and two gripping fingers 522. The finger cylinder 521 is mounted on the lifting plate 545, and the two gripping fingers 522 are respectively located at the two output ends of the finger cylinder 521. The finger cylinder 521 drives the two gripping fingers 522 to move closer or further away from each other to clamp or release the mandrel. The finger cylinder 521 has a simple structure and is easy to assemble. Moreover, the finger cylinder 521 moves quickly and has a stable clamping force, which can improve the stability of the mandrel feeding process.

[0054] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
