[0002] Electronic cigarettes convert electrical energy into heat energy, without open flames, to heat the e-liquid into atomized form for users to inhale.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] Please refer to Fig. 9The present embodiment provides a novel electronic cigarette heating element, including a first lead 110, a second lead 120, a third lead 130, a first heating sheet 140, and a second heating sheet 150; one side of the first heating sheet 140 and the second heating sheet 150 are both electrically connected to the first lead 110, and an isolation gap 145 is provided between the first heating sheet 140 and the second heating sheet 150; the side of the first heating sheet 140 away from the first lead 110 is electrically connected to the second lead 120; the side of the second heating sheet 150 away from the first lead 110 is electrically connected to the third lead 130.

[0032] Please refer to Fig. 9 The outer walls of the first lead 110, the second lead 120 and the third lead 130 are all provided with an insulating layer 160; the first heating sheet 140 and the second heating sheet 150 are metal sheets or metal mesh sheets; when the first heating sheet 140 and the second heating sheet 150 are unfolded, the third lead 130 is located between the first lead 110 and the second lead 120.

[0033] The first lead 110, the second lead 120, the third lead 130 and the first heating plate 140, the second heating plate 150 may be connected as one by welding. The first lead 110 and the second lead 120 are of equal length, and the third lead 130 is shorter than the first lead 110 and the second lead 120, but the end of the third lead 130 away from the heating plate is flush with the first lead 110 and the second lead 120.

[0034] The area of ​​the second heat generating sheet 150 is smaller than that of the first heat generating sheet 140 .

[0035] The first lead 110, the second lead 120, and the third lead 130 are provided with an insulating layer 160 and an isolation spacer 145 to prevent the heating element from short-circuiting or making it impossible for the first heating plate 140 or the second heating plate 150 to work alone.

[0036] When the first lead 110 and the second lead 120 of the heating element are respectively connected to the positive and negative electrodes of the DC battery, the first heating sheet 140 works alone to generate heat; when the first lead 110 and the third lead 130 are respectively connected to the positive and negative electrodes of the DC battery, the second heating sheet 150 works alone to generate heat.

[0037] When the first lead 110 is connected to one pole of the DC battery, and the second lead 120 and the third lead 130 are connected to the other pole of the DC battery, the first heating sheet 140 and the second heating sheet 150 work and generate heat at the same time. Therefore, the heat generation is large and rapid, which solves the problem that the user has to wait for a long time for the electronic cigarette to preheat and the required smoke output is insufficient.

[0038] Please refer to Figure 1 - Fig. 9 , a new type of electronic cigarette heating element manufacturing device, comprising:

[0039] A lead wire feeding assembly, the lead wire feeding assembly is used to transport the lead wire to be welded from the material receiving position to the welding area;

[0040] A welding limit assembly, the welding limit assembly includes a welding table 210, a wire pushing mechanism 220, and a pressing mechanism 230; the side wall of the welding table 210 is provided with a wiring guide hole 211, and the welding table 210 is provided with an alignment guide groove 213 connecting the wiring guide hole 211 and a welding table 212 for placing a heating plate; the wire pushing mechanism 220 is used to transport the lead wire to be welded from the lead wire feeding assembly into the wiring guide hole 211, and to hold the heating plate positioned against the welding table 212 through the alignment guide groove 213; the pressing mechanism 230 is used to press and position the heating plate and the lead wire.

[0041] The welding area is the area where the welding table 210 is located. The lead wires to be welded are transported by the lead wire feeding assembly. The structure of the lead wires is roughly the same thickness and length as the needle body in the handmade needlework at home, but lacks some rigidity of the needle body. As they are relatively small, it is not convenient to hold and position them manually. Therefore, the lead wire feeding assembly of the automated mechanical device clamps and moves the lead wires to be welded.

[0042] The entrance of the wiring guide hole 211 is rounded, so that the lead wire feeding assembly can more easily feed the lead wire to be welded when clamping and moving it to the wiring guide hole 211. The wiring guide hole 211 corresponds to the arrangement spacing of the power lead wires of the cost heating element, and the number is 3.

[0043] The first heating plate 140 and the second heating plate 150 are placed on the welding table 212 manually or by automated equipment, and the pressing mechanism 230 is used to press and position the upper end surfaces of the first heating plate 140 and the second heating plate 150.

[0044] The lead wire feeding assembly and the wire pushing mechanism 220 jointly drive the first lead wire 110, the second lead wire 120, and the third lead wire 130 of the wiring guide hole 211 to move synchronously, and are guided and calibrated to be placed in an orientation through the alignment guide groove 213 until they are supported against the lower end surfaces of the first heating plate 140 and the second heating plate 150 positioned on the welding table 212. Finally, the parts are welded together by an automatic welding machine or manual electric welding.

[0045] Therefore, through the electronic cigarette heating element manufacturing device, the lead and the heating plate can be automatically and accurately connected and assembled and connected, with a high yield rate and high processing efficiency. During the processing, humans are mainly responsible for debugging and observing whether the operation is correct, and the labor intensity is low.

[0046] Please refer to Figure 1 and Figure 5 , including an insulation stripping mechanism 3. When the lead wire feeding assembly transports the lead wire to be welded to the welding area and passes through the insulation stripping mechanism 3, it cooperates with the insulation stripping mechanism 3 to strip a predetermined amount of insulation from the lead wire to be welded.

[0047] When the lead wire material to be welded is a wire with an insulating layer 160 throughout, the lead wire needs to be processed before welding with the heating plate, and the insulating layer 160 at both ends of the lead wire needs to be peeled off a certain amount, that is, it does not affect the electrical connection between one end of the lead wire and the heating plate for welding, and does not affect the connection between the other end of the lead wire and the power supply of the electronic cigarette, that is, a predetermined amount of insulation needs to be peeled off.

[0048] In some embodiments, the insulation stripping mechanism 3 includes a mounting frame 310, a fifth pair of clamp driving devices 320 mounted on the mounting frame 310, a first stripping knife 330 and a second stripping knife 340 are provided on the power output end of the fifth pair of clamp driving devices 320, and the fifth pair of clamp driving devices 320 drives the first stripping knife 330 and the second stripping knife 340 to align or move away from each other.

[0049] Please refer to Figure 1 and Figure 5 , including a lead cutting mechanism 4, wherein the lead cutting mechanism 4 is used to cut the lead to be welded delivered by the lead feeding assembly into a predetermined length.

[0050] The lead cutting mechanism 4 is arranged before the process of the insulation stripping mechanism 3. The initial raw material of the lead to be welded is a continuous lead, and its length does not match the lead length required on the finished heating element. Therefore, the lead to be welded needs to be cut into a predetermined length first, corresponding to the length of the lead on the required specification heating element.

[0051] In some embodiments, the lead cutting mechanism 4 includes a sixth pair of clamping driving devices 410, and a first cutting knife 420 and a second cutting knife 430 are provided on the power output end of the sixth pair of clamping driving devices 410. The sixth pair of clamping driving devices 410 drive the first cutting knife 420 and the second cutting knife 430 to align or move away from each other. Preferably, the lead cutting mechanism 4 and the insulation stripping mechanism 3 share the mounting frame 310, and the sixth pair of clamping driving devices 410 are also mounted on the mounting frame 310.

[0052] Please refer to Figure 1 - Figure 5The lead wire feeding assembly includes a front wire feeding mechanism 510 and a transfer wire feeding mechanism 520. The front wire feeding mechanism 510 is used to transport the lead wire to be welded from the material connection position through the insulation stripping mechanism 3 to strip a predetermined amount of insulation from the lead wire to be welded; the transfer wire feeding mechanism 520 is used to receive the stripped lead wire to be welded from the front wire feeding mechanism 510 and transport it to the welding area.

[0053] In some embodiments, the lead wire feeding assembly does not include the transfer wire feeding mechanism 520, and only the front wire feeding mechanism 510 is provided, and the front wire feeding mechanism 510 finally delivers the processed lead wire to be welded to the welding area, but this setting will cause the front wire feeding mechanism 510 to move a long distance, and the corresponding front wire feeding mechanism 510 requires very high precision, and the cost is also very high, and the debugging difficulty is high, otherwise it is easy to cause very small lead feeding deviation. Or the front wire feeding mechanism 510 interferes with other components in the path.

[0054] The above disadvantages can be avoided by providing a transfer wire feeding mechanism 520 to receive the stripped leads to be welded from the front wire feeding mechanism 510 and transport them to the welding area.

[0055] Please refer to Figure 1 - Figure 4 The front wire feeding mechanism 510 includes a first linear module 511, a second linear module 512, and a third linear module 513, and a first pair of clamping driving devices 514, a second pair of clamping driving devices 515, and a third pair of clamping driving devices 516 respectively arranged at the power output ends of the first linear module 511, the second linear module 512, and the third linear module 513; the power output ends of the first pair of clamping driving devices 514, the second pair of clamping driving devices 515, and the third pair of clamping driving devices 516 are all provided with a first clamping arm 517 and a second clamping arm 518; the second clamping arm 518 is provided with a clamping groove 5181 for accommodating the lead to be welded.

[0056] In some embodiments, in order to maximize the use of space and prevent the front wire feeding mechanism 510 from occupying too much space, the first linear module 511 and the second linear module 512 are arranged in parallel side by side, and the third linear module 513 is arranged above the side of the second linear module 512. The third pair of clamping drive devices 516 are connected to the power output end of the third linear module 513 through the adjustment frame 519, so that the first clamping arm 517 and the second clamping arm 518 at the power output end of the third pair of clamping drive devices 516 extend into the first clamping arm 517 and the second clamping arm 518 at the power output end of the first pair of clamping drive devices 514 and the first clamping arm 517 and the second clamping arm 518 at the power output end of the second pair of clamping drive devices 515.

[0057] The clamping head of the first clamping arm 517 is a flat head. When the first clamping arm 517 and the second clamping arm 518 are aligned, the lead wire portion is located in the clamping groove 5181, thus preventing the lead wire from being clamped.

[0058] Please refer to Figure 5 and Figure 6 , including a positioning guide 6 and a retaining clamp mechanism 7, wherein the positioning guide 6 is provided with a wire feeding guide hole 610 corresponding to the lead to be welded. The retaining clamp mechanism 7 includes a connecting frame 710, a seventh pair of clamping driving devices 720 installed on the connecting frame 710, a fifth clamping arm 730 and a sixth clamping arm 740 provided at the power output end of the seventh pair of clamping driving devices 720; the positioning guide 6 is installed on the connecting frame 710.

[0059] The entrance of the wire feeding guide hole 610 is rounded.

[0060] Please refer to Figure 1 and Figure 5 The transfer wire feeding mechanism 520 includes a linear conveying mechanism 521, a transplanting device 522 arranged at the power output end of the linear conveying mechanism 521, a fourth pair of clamping driving devices 523 arranged at the power output end of the transplanting device 522, and a third clamping arm 524 and a fourth clamping arm 525 arranged at the power output end of the fourth pair of clamping driving devices 523; the moving direction of the fourth pair of clamping driving devices 523 driven by the transplanting device 522 is consistent with the direction of the lead wire from the wiring guide hole 211 through the alignment guide groove 213 to the welding table 212.

[0061] In some embodiments, the linear conveying mechanism 521 includes a pushing cylinder and a guide rail slide assembly. The end of the piston rod in the pushing cylinder is connected to the slide in the guide rail slide assembly, and the transplanting device 522 is installed on the slide.

[0062] The transfer device 522 may be a driving cylinder. If the direction of the alignment guide groove 213 is a vertical direction, the transfer device 522 drives the fourth clamping driving device 523 to move in a lifting direction.

[0063] Please refer to Figure 1 and Figure 7 , Figure 8 The welding limiting assembly includes a support frame 240, the support frame 240 is provided with a positioning drive device 250, and the welding table 210 is installed at the power output end of the positioning drive device 250; the wire pushing mechanism 220 includes a pushing device 221 arranged on the support frame 240 and a pushing plate 222 arranged at the power output end of the pushing device 221; the pressing mechanism 230 includes a pressing device 231 and a pressing block 232 arranged at the power output end of the pressing device 231, and the pressing block 232 is provided with a welding avoidance groove 2321; the welding table surface 212 is provided with a plurality of transverse grooves 2121.

[0064] The positioning drive device 250 can adjust the height of the welding table 210. In some embodiments, the positioning drive device 250 is a mechanism having a driving cylinder as a power source and a guide rail and guide seat assembly as a guide.

[0065] The main body of the push plate 222 is arranged against the side wall of the welding table 210, that is, the side wall where the wire guide hole 211 is located, and the push plate 222 is also provided with a sheet structure extending into the alignment guide groove 213, so that the lead wire is lifted more stably. The push device 221 is a mechanism with a driving cylinder as a power source and a guide rail and guide seat group as a guide.

[0066] The holding device 231 is a mechanism with a driving cylinder as a power source and a guide rail and guide seat assembly as a guide; the welding avoidance groove 2321 provided in the pressing block 232 is convenient for the working end of the welding gun to pass through to weld the heating plate and the lead wire, and the pressing block 232 holds the heating plate and the lead wire to prevent the relative displacement of the two and cause defective products. The transverse groove 2121 plays a role of avoiding air for the welding table 212 to prevent the heating plate and the lead wire from being welded to the welding table 210.

[0067] In the above content, each pair of clamping drive devices can be a finger cylinder, and each pair of clamping arms or cutting knives or peeling knives are respectively arranged on two power output fingers. Each pair of clamping drive devices can be two independent, oppositely arranged drive cylinders, and each pair of clamping arms or cutting knives or peeling knives are respectively arranged on the power output ends of the two drive cylinders.

[0068] The working principle of the novel electronic cigarette heating element manufacturing device is as follows: in the initial state, the three groups of long lead wire raw material ends corresponding to the first lead wire 110, the second lead wire 120, and the third lead wire 130 are passed through the three wire feeding guide holes 610 of the positioning guide 6 by manual or automated equipment, and are pulled to between the fifth clamping arm 730 and the sixth clamping arm 740, and the seventh clamping drive device 720 drives the fifth clamping arm 730 and the sixth clamping arm 740 to align, so as to clamp and position the three groups of long lead wire raw material ends.

[0069] The transplanting device 522 drives the fourth pair of clamping driving devices 523 to descend to a low position, away from the welding table 210. The linear conveying mechanism 521 drives the transplanting device 522 to retreat, close to the insulation stripping mechanism 3, and further away from the welding table 210. The first pair of clamping driving devices 514, the second pair of clamping driving devices 515, and the third pair of clamping driving devices 516 all drive the connected first clamping arms 517 and second clamping arms 518 to open;

[0070] The fifth pair of clamp driving devices 320 drives the first peeling knife and the second peeling knife to move away from each other; the sixth pair of clamp driving devices 410 drives the first cutting knife and the second cutting knife to move away from each other; the fourth pair of clamp driving devices 523 drives the third clamping arm 524 and the fourth clamping arm 525 to move away from each other and open.

[0071] After the raw materials of the first heating plate 140 and the second heating plate 150 are placed on the welding table 212, the pressing device 231 drives the pressing block 232 to approach the welding table 212 to limit the first heating plate 140 and the second heating plate 150; the pushing device 221 drives the pushing plate 222 along the outer wall of the welding table 210 away from the wiring guide hole 211.

[0072] Then, the formal processing flow is entered, the first linear module 511, the second linear module 512, and the third linear module 513 respectively drive the first pair of clamping driving devices 514, the second pair of clamping driving devices 515, and the third pair of clamping driving devices 516 to move and adjust the position of the lead to be clamped, and then the first pair of clamping driving devices 514, the second pair of clamping driving devices 515, and the third pair of clamping driving devices 516 synchronously drive the first clamping arms 517 and the second clamping arms 518 connected to them to match and clamp three groups of long lead materials; then the seventh pair of clamping driving devices 720 drives the fifth clamping arms 730, the third pair of clamping driving devices 731, and the fifth pair of clamping driving devices 732 to move and adjust the position of the lead to be clamped. The six clamping arms 740 are relatively far apart and open; the first linear module 511, the second linear module 512, and the third linear module 513 drive the first pair of clamping drives 514, the second pair of clamping drives 515, and the third pair of clamping drives 516 to move a certain distance toward the welding area, passing through the lead cutting mechanism 4, and the sixth pair of clamping drives 410 drives the first cutting knife and the second cutting knife to align and cut the three groups of long lead materials at the same time. At this time, the three groups of long lead materials are cut into lengths corresponding to the lengths of the first lead 110, the second lead 120, and the third lead 130 of the finished heating element.

[0073] Then, the first linear module 511, the second linear module 512, and the third linear module 513 continue to drive the first pair of clamping drives 514, the second pair of clamping drives 515, and the third pair of clamping drives 516 to move a certain distance toward the welding area. Before reaching the position of the first stripping knife and the second stripping knife of the insulation stripping mechanism 3, the first linear module 511, the second linear module 512, and the third linear module 513 drive the first pair of clamping drives 514, the second pair of clamping drives 515, and the third pair of clamping drives 516 to move for fine adjustment to adapt to the positions of the incisions where the insulation needs to be stripped at the front ends of the first lead 110, the second lead 120, and the third lead 130 to be in the same plane, because the third lead 130 is shorter than the first lead 110 and the second lead 120.

[0074] The first linear module 511, the second linear module 512, and the third linear module 513 drive the first pair of clamping drives 514, the second pair of clamping drives 515, and the third pair of clamping drives 516 toward the welding area. After moving to the front end stripping position, the fifth pair of clamping drives 320 drives the first stripping knife and the second stripping knife to mate. The first linear module 511, the second linear module 512, and the third linear module 513 drive the first pair of clamping drives 514, the second pair of clamping drives 515, and the third pair of clamping drives 516 toward away from the welding area until the insulation at the front end of the first lead 110, the second lead 120, and the third lead 130 falls off.

[0075] Next, the fifth pair of clamping driving devices 320 drive the first stripping knife and the second stripping knife to move away from each other, and the first linear module 511, the second linear module 512, and the third linear module 513 drive the first pair of clamping driving devices 514, the second pair of clamping driving devices 515, and the third pair of clamping driving devices 516 to move toward the welding area, and adjust the positions of the incisions where the insulation skins of the tail ends of the first lead 110, the second lead 120, and the third lead 130 need to be stripped to be in the same plane, and the first linear module 511, the second linear module 512, and the third linear module 513 drive the first pair of clamping driving devices 514, the second pair of clamping driving devices 515, and the third pair of clamping driving devices 516 to move toward the welding area. After the pair of clamping drives 514, the second pair of clamping drives 515, and the third pair of clamping drives 516 move to the tail end stripping position toward the welding area, the fifth pair of clamping drives 320 drives the first stripping knife and the second stripping knife to mate, and the first linear module 511, the second linear module 512, and the third linear module 513 drive the first pair of clamping drives 514, the second pair of clamping drives 515, and the third pair of clamping drives 516 to move toward the welding area until the insulation at the tail ends of the first lead 110, the second lead 120, and the third lead 130 fall off.

[0076] Then the first linear module 511, the second linear module 512, and the third linear module 513 drive the first pair of clamping drives 514, the second pair of clamping drives 515, and the third pair of clamping drives 516 to move, adjust the front ends of the first lead 110, the second lead 120, and the third lead 130 to be flush, and connect the first lead 110, the second lead 120, and the third lead 130 with the transfer wire feeding mechanism 520.

[0077] The fourth clamping driving device 523 drives the third clamping arm 524 and the fourth clamping arm 525 to align with each other to clamp the first lead 110, the second lead 120, and the third lead 130; the first clamping driving device 514, the second clamping driving device 515, and the third clamping driving device 516 synchronously drive the first clamping arm 517 and the second clamping arm 518 connected to them to move away from each other and open. The front wire feeding mechanism 510 is completely retracted and reset to the initial state.

[0078] The linear conveying mechanism 521 drives the transplanting device 522 to move toward the welding area, and sends the first lead 110, the second lead 120, and the third lead 130 from their front ends into the wiring guide hole 211 of the welding table 210. The pushing device 221 drives the push plate 222 to push the outer walls of the first lead 110, the second lead 120, and the third lead 130. The first lead 110, the second lead 120, and the third lead 130 are guided and calibrated to be placed in the wiring guide hole 211 through the alignment guide groove 213, and the lower end surfaces of the first heating plate 140 and the second heating plate 150 positioned against the welding table 212 are supported; at the same time, the third clamping arm 524 and the fourth clamping arm 525 clamp the first lead 110, the second lead 120, and the third lead 130 all the time, and the transplanting device 522 drives the fourth clamping driving device 523 to move synchronously with the movement of the pushing device 221 driving the push plate 222. Preventing the lead from bending can also ensure accurate alignment with the heating sheet and ensure the quality of welding connection. Moreover, the pressing block 232 is pre-pressed to the surface of the heating sheet by the pressing device 231 to prevent the heating sheet from being lifted and moved. Accurate positioning of each lead and close contact with the metal heating sheet can be achieved.

[0079] Finally, the leads and the heating element are welded together by an automatic welding machine or manual electric welding. After the welding is completed, the operation of each mechanism is restored to the initial state, and the welded heating element is taken out and waits for the next cycle.

[0080] The linear module, clamping drive device, and paired clamping arms in the front wire feeding mechanism 510 are three independent groups. Each group can be driven and moved individually to move the corresponding lead material. The relative position of each lead can also be adjusted within a certain range to accommodate leads of different lengths and specifications. The equipment has strong versatility.

[0081] By utilizing the cooperation between the front wire feeding mechanism 510 and the insulation stripping mechanism 3, the front wire feeding mechanism 510 not only plays the role of conveying the lead wire, but also plays the role of assisting in stripping the insulation skin at both ends of the lead wire.
