Description

Technical Field

[0001] The invention relates to the technical field of electronic cigarette production, and in particular to an automatic welding device for heating wires used in electronic cigarette production. Background Art

[0002] The main functions of electronic cigarettes include refreshing, satisfying smoking addiction, relieving stress and excitement. Electronic cigarettes use atomization to turn tobacco liquid into smoke for users to inhale, thereby producing a sense of euphoria and relaxation similar to cigarettes. The main function of the electronic cigarette heating wire is to heat and effectively atomize the tobacco oil to produce a smoke effect. The heating wire is one of the core components of electronic cigarettes. Powered by a battery, the heating wire heats up the surrounding tobacco oil and its dissolved substances to volatilize, forming smoke, allowing smokers to achieve the effect of puffing and exhaling smoke.

[0003] In order to make the heating wire work stably in the electronic cigarette shell during the production process, the two pins of the heating wire need to be clamped on the sealing end cover, and then the sealing end cover is clamped in the electronic cigarette shell. In order to improve the firmness of the heating wire and ensure that the heating wire is normally powered on during operation, a welding process is required to weld the pins of the heating wire to the metal connecting piece clamped on the sealing end cover, so that the metal connecting piece can be electrically connected to the battery to provide electrical energy to the heating wire. At present, tin soldering is mainly used in the process of heating wire welding. In order to improve the quality of welding, workers use flux to apply it on the welding surface before welding. In the prior art, the staff mainly apply it manually, generally directly using a brush to brush the flux onto the welding surface. In the process of brushing the flux, the amount of flux applied cannot be controlled, and it is easy to cause waste due to excessive flux application, and it is easy to reduce the welding effect due to too little flux application.‌ Summary of the invention

[0015] The present invention has the following beneficial effects:

[0016] 1. In the automatic welding device for heating wires used in the production of electronic cigarettes, the purpose of clamping the end cap can be achieved through the workpiece placement seat to avoid deviation during the welding process. The end cap and the heating wire body can be transported synchronously by the conveyor belt installed on the conveyor frame to improve the conveying efficiency. The metal connecting piece can be clamped and fixed by the unilateral movable mechanical claw. With the cooperation of the first servo electric cylinder, the metal connecting piece can be driven to achieve the purpose of inserting the metal connecting piece onto the pin and clamping it in the card slot for positioning. When the card seat moves downward, the purpose of locating the pin on the inner side of the card seat can be achieved. The working height of the soldering gun can be adjusted by the provided lifting component, which can promote soldering during the welding process. The gun moves downward to contact the pin and the metal connecting piece for soldering. The first contact frame fixed on the welding mounting plate can be moved downward synchronously with the soldering gun during welding. In the process of the first contact frame moving downward, the purpose of contacting the contact rotating frame can be achieved. Through the cooperation of the T-shaped contact rod and the first torsion spring, the purpose of pushing the flux circulation seat against the surface of the pin during the movement of the contact rotating frame can be achieved. Through the cooperation of the injection tube, the flux circulation seat and several nozzles, the purpose of the flux conveying device conveying the flux from the injection tube to the flux circulation seat and spraying it quantitatively by the nozzle can be achieved, thereby controlling the amount of flux applied and avoiding excessive or insufficient use of flux.

[0017] 2. In the automatic welding device for heating wires used in the production of electronic cigarettes, the telescopic component fixed on the arc-shaped tooth piece can realize the purpose of the semicircular brush piece being against the welding surface of the pin and the metal connecting piece. When the flux flows to the welding surface, it can contact the semicircular brush piece. The first sliding rod connected to the holder can drive the first interfering wedge to interfere with the forming nozzle on the end cover when the holder moves downward, so that the first sliding rod drives the rack to move horizontally in the holder. Since the rack is meshed with the upper end of the double-linked gear, the arc-shaped tooth piece meshed at the lower end of the double-linked gear is deflected on the rotating shaft, which can cause the semicircular brush piece to rotate. The tamping rod fixed on the welding mounting plate can move synchronously during the downward movement of the tin soldering gun. , which can achieve the purpose of breaking and removing the formed nozzle during the welding process, improve the appearance of the end cover, and also achieve the purpose of releasing the interference between the formed nozzle and the first interference wedge, so that the arc-shaped tooth piece can drive the semicircular brush piece to rotate during the resetting process so that the flux can be evenly applied to the welding surface, thereby improving the soldering quality during the welding process. The second interference wedge block arranged on the holder can interfere with the first interference frame as the soldering gun moves downward, prompting the second interference wedge block to move downward and interfere with the interference strip fixed on one side of the semicircular brush piece, so that the semicircular brush piece can be kept away from the pin during the soldering process of the soldering gun, thereby avoiding obstruction to the welding of the pin and the metal connecting piece, and affecting the welding quality.

[0018] 3. In the automatic welding device for heating wires used in the production of electronic cigarettes, the second sliding rods fixed on both sides of the card seat are conveniently elastically connected to the sliding plates fixed on the cutter. The rotating rods that are rotatably connected between the strip plate and the cutter can drive the cutter to move horizontally when the strip plate moves upward. The contact head elastically connected to the first contact frame can be deflected by the strip plate during the downward movement, so that the contact head can be moved down to the bottom of the strip plate. When the tin soldering gun completes the upward movement, the contact head can automatically drag the strip plate to move upward synchronously, prompting the cutter to approach the pin, so as to facilitate the automatic cutting of the excess length of the pin and avoid the pin being too long to affect the use.

[0031] The lifting assembly includes a second servo electric cylinder 131 , which is fixed on the base plate 1 , and a welding mounting plate 132 is fixed to the end of the second servo electric cylinder 131 , the soldering gun 13 is fixed on the welding mounting plate 132 , and a first abutment frame 133 is fixed on the welding mounting plate 132 .

[0032] A resistance rotating frame 19 is slidably connected inside the holder 11, and a second spring 191 is mounted on the resistance rotating frame 19. Both ends of the second spring 191 are respectively connected to the resistance rotating frame 19 and the holder 11. A T-shaped resistance rod 20 is rotatably connected inside the holder 11, and a first torsion spring 21 is connected between the T-shaped resistance rod 20 and the holder 11. One end of the resistance rotating frame 19 is in resistance to the T-shaped resistance rod 20, and one end of the flux circulation seat 14 is in resistance to the T-shaped resistance rod 20.

[0033] During welding, refer to Figure 1-Figure 6 , place the end cover 5 together with the heating wire body 6 in the workpiece placement seat 4, and transport them through the conveyor belt 3 installed on the conveyor frame 2, and clamp and fix the metal connecting piece 12 through the unilateral movable mechanical claw 9. When the end cover 5 is located below the tin soldering gun 13, the first servo electric cylinder 8 adjusts the height of the unilateral movable mechanical claw 9, driving the metal connecting piece 12 and the holder 11 fixed on the movable end of the unilateral movable mechanical claw 9 to move downward, so that the metal connecting piece 12 is stuck in the slot 10 opened on the end cover 5, and is sleeved on the pin 7 on the heating wire body 6. At the same time, the pin 7 is located inside the holder 11, and the height of the welding mounting plate 132 is adjusted by the second servo electric cylinder 131 in the lifting assembly, so that the welding mounting plate 132 drives the tin soldering gun 13 and the first contact frame 133 to move downward synchronously, so that the first contact frame 1 33 comes into conflict with the conflict rotating frame 19 inside the card seat 11, and the conflict rotating frame 19 moves horizontally. At the same time, the second spring 191 accumulates force. The horizontal movement of the conflict rotating frame 19 can conflict with one end of the T-shaped conflict rod 20, so that the T-shaped conflict rod 20 can be deflected inside the card seat 11. At the same time, the first torsion spring 21 accumulates force. When the T-shaped conflict rod 20 is deflected, it can push the flux circulation seat 14 to slide horizontally on the strip block 17, so that the multiple nozzles 15 arranged on the flux circulation seat 14 are close to the surface of the pin 7. At the same time, the first spring 18 accumulates force and is connected with the injection pipe 16 through the conveying equipment, so as to realize the purpose of conveying the flux into the flux circulation seat 14 and spraying it quantitatively by the nozzle 15, so as to control the amount of flux applied and avoid the phenomenon of excessive or insufficient use of flux.

[0034] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figures 1 to 9A rotating shaft 22 is rotatably connected to both sides of the card seat 11, and an arc-shaped tooth piece 23 is slidably connected to the rotating shaft 22. A telescopic component is fixed to one side of the arc-shaped tooth piece 23, and a semicircular brush piece 24 is fixed to one end of the telescopic component. A double gear 25 is rotatably connected to the card seat 11, and the lower end of the double gear 25 is meshed with the arc-shaped tooth piece 23.

[0035] A forming nozzle 26 is integrally formed on the end cover 5, and first slide bars 27 are slidably connected to both sides of the holder 11. A third spring 28 is fixed between the first slide bar 27 and the holder 11. A first abutting wedge 29 is fixed to one end of the first slide bar 27, and a rack 30 is fixed to the other end of the first slide bar 27. The rack 30 is meshed with the upper end of the double gear 25, and a tamping rod 31 is fixed to the welding mounting plate 132.

[0036] The telescopic assembly includes a hollow column 231 , which is fixed on the arc-shaped tooth piece 23 . A connecting rod 232 is slidably connected inside the hollow column 231 . One end of the connecting rod 232 is fixed on the semicircular brush piece 24 . A fourth spring 233 is fixed between the hollow column 231 and the connecting rod 232 .

[0037] A second abutting wedge 32 is slidably connected to the holder 11 , a fifth spring 33 is fixed between the second abutting wedge 32 and the holder 11 , an abutting strip 34 is fixed to one side of the semicircular brush piece 24 , and the second abutting wedge 32 abuts against the abutting strip 34 .

[0038] In the prior art, the flux is mostly applied by brush, which easily leads to uneven flux application on the welding surface, which affects the quality of welding. The molding nozzle 26 on the end cap 5 is the inlet part where the plastic melt flows into the mold cavity during the injection molding of the end cap 5. It needs to be removed after welding. Figure 3-Figure 6When the first servo electric cylinder 8 drives the holder 11 to move downward, the first abutting wedges 29 fixed on the first slide bars 27 on both sides of the holder 11 come into contact with the forming nozzle 26, causing the end of the first slide bar 27 to move horizontally toward the inside of the holder 11. At the same time, the third spring 28 accumulates force. The first slide bar 27 can drive the rack 30 to move horizontally during the movement, causing the double gear 25 meshing with the rack 30 to rotate, so that the arc-shaped tooth piece 23 meshing with the lower end of the double gear 25 deflects on the rotating shaft 22, which can cause the semicircular brush piece 24 to rotate around the welding surface of the pin 7. The tamping rod 31 fixed on the mounting plate 132 can move synchronously during the downward movement of the soldering gun 13. When the tamping rod 31 abuts against one side of the forming nozzle 26, the applied force can cause the forming nozzle 26 to break. When the tamping rod 31 continues to move downward and abuts against the end cover 5, one side of the forming nozzle 26 is squeezed by the tamping rod 31, and the purpose of flipping to one side can be achieved, so that the forming nozzle 26 and the first abutting wedge 29 are released from the abutment, so that the semicircular brush piece 24 can be driven to rotate during the resetting process of the arc-shaped tooth piece 23, so that the flux can be evenly applied to the welding surface, which can greatly improve the quality of welding. refer to Figure 3-Figure 7 In order to prevent the semicircular brush piece 24 close to the pin 7 from hindering welding, it is necessary to adjust the position of the semicircular brush piece 24 during welding. When the tin soldering gun 13 moves down and approaches the welding surface, the first interference frame 133 continues to move downward and interferes with the second interference wedge block 32 provided in the holder 11, prompting the second interference wedge block 32 to move downward. The fifth spring 33 accumulates force so that the second interference wedge block 32 can interfere with the interference strip 34 fixed on one side of the semicircular brush piece 24. The connecting rod 232 contracts in the hollow column 231, and the fourth spring 233 accumulates force, which can achieve the purpose of keeping the semicircular brush piece 24 away from the pin 7, and can leave enough welding space during welding. The soldering gun 13 is an automatic soldering machine with an automatic wire feeding function, which can automatically feed the solder wire into the soldering gun to facilitate continuous welding operations.

[0039] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figures 1 to 9 Two second slide bars 35 are fixed on both sides of the card holder 11, and a sliding sheet 36 is slidably connected to the second slide bars 35. A cutter 37 is fixed on the sliding sheet 36, and the sliding sheet 36 is elastically connected to the card holder 11 through a sixth spring 38.

[0040] A strip plate 39 is provided in the holder 11 . Both ends of the strip plate 39 are rotatably connected to a rotating rod 40 . One end of the rotating rod 40 is rotatably connected to one end of the cutter 37 .

[0041] The first abutment frame 133 is provided with a mounting groove 41 , and a abutment head 42 is disposed in the mounting groove 41 . The abutment head 42 is elastically connected to the first abutment frame 133 via a second torsion spring 43 .

[0042] Some pins 7 currently used are relatively long, which can provide a more stable welding environment during the welding process, reduce welding defects, improve deposition efficiency and reduce welding deformation, thereby improving welding quality and efficiency. However, after welding, the excessive length of pin 7 will affect the assembly effect in the subsequent process of electronic cigarette production, and it is necessary to use shearing equipment for shearing. When shearing is performed by shearing equipment, it will increase the production time of electronic cigarettes and reduce production efficiency. Figure 3-Figure 5 When the first contact frame 133 moves downward with the tin soldering gun 13, it can drive the contact head 42 to move downward synchronously. During the movement, the contact head 42 can come into contact with the strip plate 39. The contact head 42 will deflect under the influence of the contact force. The second torsion spring 43 performs preliminary force accumulation, so that the first contact frame 133 can drive the contact head 42 to move to the bottom of the strip plate 39. The second torsion spring 43 releases the elastic force, and the contact head 42 returns to its initial state. When the tin soldering gun 13 is moved upward after welding, the contact head 42 comes into contact with the strip plate 39, which can achieve the purpose of driving the strip plate 39 to move up to a certain height. The strip plate 39 moves upward During the process, the rotating rod 40 can be dragged to deflect, and the sliding piece 36 fixed on the cutter 37 can be pulled to move horizontally on the second sliding rod 35. The sixth spring 38 accumulates force to achieve the purpose of cutting off the pin 7 with excess length, so as to prevent the pin 7 from being too long to affect the use. When the strip plate 39 rises to a certain height and cannot continue to move, the contact head 42 overcomes the resistance of the second torsion spring 43 and deflects. As the contact head 42 deflects, the contact head 42 is staggered with the strip plate 39. At this time, the existence of the contact head 42 will not hinder the movement of the strip plate 39, and the strip plate 39 and the cutter 37 return to their original positions driven by the sixth spring 38.

[0043] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
