Description

Technical Field

[0001] This invention relates to the field of electronic cigarette processing technology, specifically to a welding device for processing electronic cigarette heating wires. Background Technology

[0002] The heating wire in an electronic cigarette is one of the components that makes up the atomizer core. After being heated by electrodes, the heating wire heats up the e-liquid impregnated on its surface, bringing it to its boiling point and producing vapor. The heating wire acts like a resistor, and its resistance is determined by four factors: wire length, cross-sectional area, material, and temperature. Commonly used heating wire materials include ceramic and stainless steel.

[0003] In existing technologies, the installation of the heating wire requires multiple steps. First, a section of heating wire is cut and wound around the wire manually or mechanically; the number of turns determines the resistance value. Then, the two ends of the heating wire are connected to the two electrodes on the e-cigarette by welding or bolting. This processing method requires an additional step on the production line, and if the winding is done manually, it consumes additional manpower, both of which reduce the production efficiency of e-cigarettes.

[0004] Therefore, in order to solve the above-mentioned technical problems in the existing technology, a welding device for processing electronic cigarette heating wires is proposed. Summary of the Invention

[0026] 1. This welding equipment for electronic cigarette heating wire processing integrates the welding and winding processes of the heating wire into one step.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1, please refer to Figures 1-8 A welding device for processing heating wires for electronic cigarettes includes a base 100, a turntable 180 rotatably mounted on the base 100, a plurality of material grooves 130 circumferentially opened on the turntable 180, an electronic cigarette body 200 is disposed in each of the plurality of material grooves 130, and two electrodes 210 are symmetrically arranged on the electronic cigarette body 200.

[0043] Two first cylinders 250 and two conveying components 270 are symmetrically arranged on the base 100. The conveying components 270 are used to convey the heating wire 230. The piston rod of the first cylinder 250 is equipped with a welding torch 260. The base 100 is also equipped with a winding mechanism 300 and a spiral propulsion mechanism 400.

[0044] After several electronic cigarette bodies 200 are sequentially transported to the transport assembly 270 via the turntable 180, the heating wire 230 is transported through one of the transport assemblies 270 and passes through one of the electrodes 210. Then, the heating wire 230 is held by the winding mechanism 300.

[0045] The spiral propulsion mechanism 400 drives the winding mechanism 300 to make spiral movement to wind the heating wire 230 several times. Then, the heating wire 230 is conveyed through another electrode 210 by another conveying component 270, and then the heating wire 230 is welded to the two electrodes 210 by two welding guns 260.

[0046] It also includes a first motor 150 and a second motor 240. The output shaft of the first motor 150 is connected to the turntable 180. The second motor 240 is mounted on the base 100. A winding drum 220 is mounted on the output shaft of the second motor 240, and the heating wire 230 is wound on the winding drum 220.

[0047] The winding mechanism 300 includes two support seats 310 symmetrically arranged on the base 100. A cylinder 320 is slidably arranged on each of the two support seats 310. One cylinder 320 is provided with a plurality of inner support plates 330 in the circumferential direction, and the other cylinder 320 is provided with a plurality of outer support plates 340 in the circumferential direction.

[0048] The heating wire 230 is clamped by conveying the conveying assembly 270 between several inner support plates 330 and several outer support plates 340.

[0049] The conveying assembly 270 includes two fourth cylinders 272 symmetrically arranged on the base 100. Each of the piston rods of the two fourth cylinders 272 is provided with a movable frame 271. Each of the two movable frames 271 is rotatably provided with a conveying wheel 273. Each of the two movable frames 271 is provided with a third motor 274. The output shafts of the two third motors 274 are respectively connected to the two conveying wheels 273.

[0050] A fifth cylinder 280 is installed on the base 100. A cutting machine 290 is installed on the piston rod of the fifth cylinder 280. After the heating wire 230 is welded to the two electrodes 210, the heating wire 230 is cut by the cutting machine 290.

[0051] It also includes a first belt conveyor 110, a second belt conveyor 120 and a fourth motor 160. The first belt conveyor 110 is used to convey the electronic cigarette body 200 without the heating wire 230 to the turntable 180. The output shaft of the fourth motor 160 is provided with a tooth 140.

[0052] The second belt conveyor 120 is used to transport the electronic cigarette body 200 with the heating wire 230 welded out from the turntable 180. The base 100 is provided with a guide plate 170, which is located between the turntable 180 and the second belt conveyor 120.

[0053] In this embodiment: the first belt conveyor 110 can be installed on the ground and is connected to the upstream of the electronic cigarette production line. The first belt conveyor 110 can be composed of pulleys, belts, motors, etc. A large number of electronic cigarette bodies 200 are arranged from right to left on the belt of the first belt conveyor 110 and conveyed to the left. When passing through the toothed teeth 140, the toothed teeth 140 can be driven to rotate by the fourth motor 160 installed on the ground. The toothed teeth 140 have multiple semi-circular grooves that fit with the electronic cigarette bodies 200. Each time it rotates through a semi-circular groove, a large number of electronic cigarette bodies 200 can be conveyed to the left at equal intervals.

[0054] Once an electronic cigarette body 200 reaches the base 100 and falls into one of the feed troughs 130, the first motor 150 mounted on the ground drives the turntable 180 to rotate, thus conveying the electronic cigarette bodies 200 one by one counterclockwise. The turntable 180 is a hollow disc, and the base 100 consists of a centrally fixed shaft and an outer ring. The devices for winding and welding are mounted on the central shaft and the outer ring.

[0055] When the electronic cigarette body 200 rotates counterclockwise half a turn to the left-side winding and welding device, the first belt conveyor 110 and turntable 180 stop operating. A set of conveyor components 270 located at the front can be installed at an angle from the upper front to the lower rear, allowing the electrode 210 on the electronic cigarette body 200 to pass under the conveyor components 270. Within the set of conveyor components 270 at the front, two fourth cylinders 272 can drive two movable frames 271 to adjust their position left and right to align with the front electrode 210.

[0056] First, in a set of conveying components 270 on the front side, two third motors 274 drive the left conveying wheel 273 to rotate counterclockwise and the right conveying wheel 273 to rotate clockwise. This conveys one end of the heating wire 230 sandwiched in the middle through the front electrode 210 and then squeezes it between several inner support plates 330 and several outer support plates 340 for a certain degree of fixation.

[0057] Then, the spiral propulsion mechanism 400 drives the two cylinders 320 to move counterclockwise spirally to the left in sync, so that the heating wire 230 is wound around the inner support plates 330 on the right side to form a counterclockwise spiral shape.

[0058] After winding is completed, the process stops. Then, controlled by two fourth cylinders 272 of a set of conveying components 270 located at the rear, the two moving frames 271 are moved closer together, causing the two conveying wheels 273 to clamp the extended head of the heating wire 230. Then, the heating wire 230 is conveyed to the rear through the electrode 210 located at the rear by two third motors 274. During this process, the second motor 240 can drive the winding drum 220 to rotate clockwise to actively convey the heating wire 230.

[0059] Then, the two first cylinders 250 can be controlled to drive the two welding guns 260 to approach the two electrodes 210 respectively for welding, fixing the heating wire 230 on the two electrodes 210. Then, the fifth cylinder 280 drives the cutting machine 290 to cut the part between the heating wire 230 located on the front electrode 210 and the front conveying assembly 270. The welding work is thus completed.

[0060] Then, the turntable 180 continues to run and transport the welded electronic cigarette body 200 counterclockwise until it reaches the guide plate 170. After being guided by the guide plate 170, it falls onto the second belt conveyor 120. The second belt conveyor 120 then transports the welded electronic cigarette body 200 from right to left to the downstream of the electronic cigarette production line.

[0061] It should be noted that the first belt conveyor 110, the second belt conveyor 120, the welding torch 260, and the cutting machine 290 are conventional technical means, and their specific structures and working principles will not be described in detail.

[0062] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-11 An inner clamping plate 350 is provided on one of the inner support plates 330, and an outer clamping plate 360 ​​is provided on one of the outer support plates 340. A first spiral groove 390 is provided on the outer wall of several inner support plates 330 and the inner wall of several outer support plates 340.

[0063] When the heating wire 230 is conveyed between the inner clamping plate 350 and the outer clamping plate 360 ​​to clamp the heating wire 230, and then the two cylinders 320 are driven to move in a spiral motion by the spiral propulsion mechanism 400, the inner clamping plate 350 and the outer clamping plate 360 ​​drive the heating wire 230 to spirally wind around the first spiral groove 390.

[0064] The screw propulsion mechanism 400 includes two second cylinders 410 symmetrically arranged on the base 100. Each of the piston rods of the two second cylinders 410 is provided with a connecting rod 420, and the two cylinders 320 are rotatably connected to the two connecting rods 420 respectively.

[0065] The support base 310 has a second spiral groove 430. The pitch and number of turns of the second spiral groove 430 are the same as those of the first spiral groove 390. The cylinder 320 is provided with a slider 440, which is slidably connected to the second spiral groove 430.

[0066] In this embodiment: Furthermore, in order to make the middle part of the heating wire 230 wound into a spiral shape more precise in terms of the number of turns and the size of each turn, an inner clamping plate 350 and an outer clamping plate 360 ​​are used to replace the inner support plate 330 and the outer support plate 340 in clamping the heating wire 230. Figure 6 The middle position is the state of the inner clamping plate 350 and the outer clamping plate 360 ​​when the heating wire 230 just reaches the winding mechanism 300. At this time, after the heating wire 230 passes between the inner clamping plate 350 and the outer clamping plate 360, the head of the heating wire 230 can be clamped by controlling the inner support plate 330 connected to the inner clamping plate 350 to move outward based on the radius direction of the cylinder 320, and controlling the outer support plate 340 connected to the outer clamping plate 360 ​​to move inward based on the same radius direction.

[0067] The second cylinder 410 on the right and the connecting rod 420 push the right cylinder 320 to the left, causing the slider 440 on the right cylinder 320 to move counterclockwise to the left along the second spiral groove 430. Meanwhile, the second cylinder 410 on the left and the connecting rod 420 pull the left cylinder 320 to the left, causing the left cylinder 320 to also move counterclockwise to the left.

[0068] This causes the heating wire 230 to begin to move counterclockwise to the left in a spiral motion, and with the presence of the first spiral groove 390, the heating wire 230 will precisely fall on each turn of the first spiral groove 390, which plays a reinforcing role and can prevent the wound heating wire 230 from deforming.

[0069] Furthermore, the specific number of turns of the heating wire 230 is also controllable. The number of turns in both the first spiral groove 390 and the second spiral groove 430 is set to be relatively large. When the number of turns is different, it can be adapted by adjusting the mating position of the two conveying wheels 273 located on the rear conveying assembly 270. Additionally, the rear conveying assembly 270 can be mounted on a motor-driven rotating device and adjusted to align with the rear electrode 210.

[0070] Example 3 is an improvement upon Example 2. For details, please refer to [link / reference]. Figures 2-11 One of the cylinders 320 has several first grooves 370 circumferentially open, and several inner support plates 330 are slidably connected to the several first grooves 370 respectively. The other cylinder 320 has several second grooves 380 circumferentially open, and several outer support plates 340 are slidably connected to the several second grooves 380 respectively.

[0071] Both cylinders 320 are equipped with telescopic mechanisms 500, which are used to drive several inner support plates 330 and several outer support plates 340 to perform radial telescopic movements.

[0072] The telescopic mechanism 500 includes a slide block 510 slidably disposed inside a cylinder 320. A third cylinder 520 is disposed on the cylinder 320. The piston rod of the third cylinder 520 is connected to the slide block 510. Several first connecting seats 530 are disposed circumferentially on the slide block 510. Several second connecting seats 540 are disposed on several inner support plates 330.

[0073] The telescopic mechanism 500 also includes several transmission rods 550. One end of each transmission rod 550 is movably hinged to several first connecting seats 530 via hinge pins, and the other end of each transmission rod 550 is movably hinged to several second connecting seats 540 via hinge pins.

[0074] In this embodiment: in addition to the adjustable number of turns of the heating wire 230, the diameter of its spiral portion can also be adjusted. Several inner support plates 330 and several outer support plates 340 can move radially based on several radial directions of the two cylinders 320.

[0075] When the inner clamping plate 350 and the outer clamping plate 360 ​​initially clamp the heating wire 230, the third cylinder 520 located on the right pushes the slide 510 to move to the left. Through the transmission of several second connecting seats 540, several inner support plates 330 connected to several second connecting seats 540 move radially outward based on the radius direction of the cylinder 320.

[0076] The third cylinder 520 on the left pushes the slide 510 to move to the left, causing the outer support plates 340 connected to the second connecting seats 540 to move radially inward based on the radius of the cylinder 320.

[0077] After the heating wire 230 is inserted into the rear electrode 210 and welded, the right-side slide 510 is moved to the right, causing several inner support plates 330 to move radially towards each other based on the radius of the cylinder 320, separating them from the spiral portion of the heating wire 230. The left-side slide 510 is moved to the right, causing several outer support plates 340 to move radially away from each other based on the radius of the cylinder 320, disengaging them from the spiral portion of the heating wire 230. Simultaneously, the inner clamping plate 350 and the outer clamping plate 360 ​​also move away from each other and disengage from the heating wire 230. Then, by moving the right-side connecting rod 420 spirally to the right and the left-side connecting rod 420 spirally to the left, several inner support plates 330 and several outer support plates 340 are pulled out from the spiral portion of the heating wire 230.

[0078] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0079] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
