Description

Technical Field

[0001] This invention relates to the field of electronic cigarettes, specifically to electronic cigarette production and assembly equipment. Background Technology

[0002] Electronic cigarettes are electronic products that mimic traditional cigarettes. Although they do not contain tar, they have the same appearance, smoke, taste, and feel as traditional cigarettes. There are many types and styles of electronic cigarettes. Some are reusable, while others are disposable. Reusable electronic cigarettes can be recharged and discharged repeatedly. For hygiene and safety, they are designed with replaceable mouthpieces, meaning that the mouthpiece can be removed from the electronic cigarette and replaced with a new one.

[0003] There are several ways to connect the mouthpiece to the e-cigarette body. Some are connected by a bayonet, some by a threaded connection, and some by a magnetic connection. In an e-cigarette connected by a magnetic connection, there are symmetrical strong magnets, usually neodymium magnets, at the end of the e-cigarette body. Two symmetrical iron blocks are placed on the mouthpiece, and the iron blocks are attracted to the strong magnets. The mouthpiece is then snapped onto the end of the e-cigarette body, completing the mouthpiece assembly.

[0004] The small size of the cigarette holder itself makes the assembly of the iron block even smaller, resulting in greater assembly difficulties, especially for manual operation. The iron blocks are placed one by one into the groove on the cigarette holder, requiring both the cigarette holder and the iron block to be stabilized. Furthermore, with assembly line production and a large number of assembly tasks every day, the assembly line workers are in a highly concentrated state for long periods of time, which not only leads to low efficiency but also increases the defect rate due to improper assembly of the iron blocks.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Reference Figures 1-8 An electronic cigarette manufacturing and assembly device includes a transfer unit for transferring a mouthpiece 1 of an electronic cigarette. A positioning component, a feeding component, and a discharging component are sequentially arranged clockwise on the outer side of the transfer unit. Above the transfer unit, a glue spraying component and a pressing component are sequentially arranged clockwise. The glue spraying component is close to the positioning component. The positioning component pushes the mouthpiece 1 onto the transfer unit, and the glue spraying component sprays glue onto the mouthpiece 1. The feeding component installs an iron block 3 that mates with the mouthpiece 1 onto the mouthpiece 1. The pressing component firmly presses the iron block 3 onto the mouthpiece 1. The discharging component works synchronously with the positioning component and discharges the mouthpiece 1 that has been installed on the transfer unit.

[0033] In this embodiment, a high-efficiency electronic cigarette production and assembly equipment is provided. The mouthpieces 1 of the electronic cigarette are placed one by one on the transfer unit. Then, the transfer unit rotates clockwise to the side of the positioning component, which is also below the glue spraying component. At this time, the positioning component pushes the mouthpiece 1 to accurately install the mouthpiece 1 on the transfer unit. Then, the glue spraying component sprays liquid glue into the groove on the mouthpiece 1. Then, the transfer unit rotates clockwise again to push the mouthpiece 1 to the feeding component. Then, the feeding component accurately transfers the iron block 3 into the groove. Then, the transfer unit rotates clockwise again to transfer the mouthpiece 1 to the bottom of the pressing component. The pressing component further presses the iron block 3 into the groove to improve the firmness of the iron block 3. Then, the transfer unit rotates clockwise again to transfer the mouthpiece 1 to the unloading component. The unloading component, in conjunction with the action of the positioning component, not only accurately installs the new mouthpiece 1 on the transfer unit, but also unloads the assembled mouthpiece 1.

[0034] In the process of this electronic cigarette production and assembly equipment, the components are sequentially passed through the transfer unit to achieve positioning of mouthpiece 1, glue spraying, assembly of iron block 3, pressing of iron block 3 and unloading of mouthpiece 1. Each environment does not affect the others. Compared with manual assembly, it is more efficient and has a lower defect rate.

[0035] Reference Figures 1-4 The transfer unit includes a turntable 2, and a motor is fixed to the lower surface of the turntable 2. The motor drives the turntable 2 to rotate clockwise intermittently. Multiple mounting slots 4 are opened on the outer ring of the turntable 2. An inverted cigarette holder 1 is embedded in the mounting slot 4. The upper end of the cigarette holder 1 protrudes from the upper surface of the turntable 2, and the lower end of the cigarette holder 1 protrudes from the lower surface of the turntable 2.

[0036] The positioning component includes a first cylinder 5, with a pressing plate 6 fixedly connected to the output end of the first cylinder 5. The pressing plate 6 is arc-shaped, and its concave surface shape matches the outer surface shape of the cigarette holder 1. The turntable 2 is driven by a motor. Assuming that the turntable 2 has n mounting slots 4, the turntable 2 rotates intermittently by 360 / n° each time. The area between the feeding component and the glue spraying component is designated as station 7. The position on the turntable 2 opposite to the glue spraying component is designated as station 8. The position on the turntable 2 opposite to the feeding component is designated as station 9. The position on the turntable 2 opposite to the pressing component is designated as station 10. The position on the turntable 2 opposite to the feeding component is designated as station 11. The turntable 2 rotates, transferring the cigarette holder 1, and the cigarette holder 1 passes through the... The process proceeds through stations 7, 8, 9, 10, and 11. At station 7, the cigarette holder 1 is fed into the mounting slot 4. Then, the turntable 2 rotates, transferring the cigarette holder 1 to station 8 for clamping. This ensures that the cigarette holder 1 is fully assembled into the mounting slot 4 during feeding at station 7, which would affect the accuracy of glue spraying and the placement of the iron block 3. When the cigarette holder 1 is transferred to station 8, the positioning component is first activated. Cylinder 5 pushes the extrusion plate 6, which presses the cigarette holder 1 into place. Once the position of the cigarette holder 1 is confirmed, cylinder 5 moves the extrusion plate 6 back to its original position, and then the glue spraying component is activated.

[0037] Reference Figures 1-6 A glue spraying assembly is installed above the mouthpiece 1 corresponding to the extrusion plate 6. The glue spraying assembly includes a second cylinder 12, the output end of which points vertically to the upper end of the mouthpiece 1. A horizontal plate 13 is fixedly connected to the output end of the second cylinder 12. Hollow tubes are fixedly connected to both sides of the lower surface of the horizontal plate 13. The hollow tubes are connected to an external pump body through a flexible hose 15. A nozzle 16 is fixedly connected to the lower end of the hollow tube. The diameter of the nozzle 16 is smaller than the diameter of the groove on the mouthpiece 1 where the iron block 3 is installed. The iron block 3 needs to be glued to the groove on the mouthpiece 1 to ensure the adhesion between the iron block 3 and the mouthpiece 1. The adhesive is applied to ensure the stability between the mouthpiece 1 and the electronic cigarette body. The adhesive spraying process is as follows: first, the second cylinder 12 is driven, and the hollow tube is lowered by the second cylinder 12. The nozzle 16 moves into the groove. Then, the external pump head injects the adhesive into the hollow tube and sprays it out from the nozzle 16 onto the surface of the groove. In this embodiment, to ensure the uniformity of the amount of adhesive sprayed, it is recommended to use a peristaltic pump. The diameter of the nozzle 16 is designed to ensure that the nozzle 16 can extend into the groove before spraying the adhesive, so as to prevent the adhesive from being sprayed outside the groove and contaminating the mouthpiece 1.

[0038] Reference Figures 1-5The feeding assembly includes a third cylinder 17, the output end of the third cylinder 17 is vertically downward, the outer ring of the output end of the third cylinder 17 is rotatably connected to a hollow ring 18, one side of the ring 18 is connected to an external negative pressure pump through an air pipe 19, the output end of the third cylinder 17 is rotatably connected to a rotating plate 20, and suction cups 21 are symmetrically provided on the lower surfaces of both ends of the rotating plate 20. The suction cups 21 are connected to the ring 18 through a branch pipe 22. The suction cups 21 are used to adsorb the iron block 3 to be installed. The branch pipe 22 is laid on the upper surface of the rotating plate 20.

[0039] A rotating shaft 23 is fixedly connected to the middle of the lower surface of the rotating plate 20. A driven tooth 24 is fixedly connected to the outer ring of the rotating shaft 23. The driven tooth 24 meshes with a driving tooth 25, which is driven by a servo motor. A guide rail 26 is also provided on one side of the feeding assembly. Two guide grooves are provided in the guide rail 26, and the iron blocks 3 to be assembled are placed in the guide grooves. The servo motor rotates alternately in forward and reverse directions, thereby driving the rotating plate 20 to rotate alternately in forward and reverse directions. When the feeding assembly is in operation, the turntable 2 rotates the glue-sprayed mouthpiece 1 to the position of station 9. The output end of cylinder 17 presses down on the rotating plate 20. The iron block 3 is adsorbed on the suction cup 21 on the rotating plate 20 near the turntable 2. The iron block 3 gradually approaches the groove on the mouthpiece 1 below it. Finally, the iron block 3 is lowered and pushed into the groove, and the iron block 3 is adhered to the groove by the glue. At the same time, the suction cup on the end of the rotating plate 20 away from the turntable 2... 21 moves down and approaches the iron block 3 on the guide rail 26, and attracts the iron block 3. Then, the third cylinder 17 drives the rotating plate 20 to move up and reset. The adhesive force of the glue is greater than the suction force of the suction cup 21 to attract the iron block 3. Therefore, during the upward movement of the rotating plate 20, the suction cup 21 will not carry the iron block 3 away from the groove. Then the turntable 2 rotates, rotating the mouthpiece 1 equipped with the iron block 3 from the third station 9 to the fourth station 10. At the same time, the servo motor drives the rotating plate 20 to rotate 180 degrees forward / reverse through the engagement of the active tooth 25 and the driven tooth 24. At this time, the suction cup 21 with the iron block 3 moves to the mouthpiece 1 that just entered the third station 9. Then the above actions are repeated. The structural design of this feeding component can realize the accurate assembly of the iron block 3, and also reduce the preparation time of the iron block 3. During the feeding time of the iron block 3, a new iron block 3 is picked up and prepared, and the interval time is reused.

[0040] Reference Figures 1-5The pressing assembly includes an extension plate 27. One end of the extension plate 27 is on the output end of the third cylinder 17, and the extension plate 27 and the third cylinder 17 are fixedly connected above the ring body 18. The other end of the extension plate 27 is provided with a pressure rod 28, which is connected to the lower surface of the extension plate 27 by a spring. The lower end of the pressure rod 28 presses against the iron block 3. As mentioned above, the suction cup 21 pushes the iron block 3 into the groove, and then the suction cup 21 moves upward. At this time, the inside of the suction cup 21 is always in a negative pressure state, even if the suction cup 21 is insufficient to pick up the iron block 3 in the groove. The lifting strap is removed from the groove, but this will also affect the position between the iron block 3 and the groove. The iron block 3 may be dragged and suspended in the groove, and the iron block 3 may not be accurately assembled in the groove. For this reason, a pressing component is set up. The turntable 2 transfers the cigarette holder 1 from station 9 to station 10. During the process of the cylinder 17 driving the rotating plate 20 to move down, it also drives the extension plate 27 to move down. The extension plate 27 drives the lower end of the pressure rod 28 to approach the iron block 3 at station 10. The lower end of the pressure rod 28 presses down on the iron block 3, pressing the iron block 3 to the bottom of the groove to ensure that the iron block 3 is installed in place.

[0041] Reference Figures 1-7 The feeding assembly includes a U-shaped rod 29 with its opening facing downwards towards the turntable 2. The upper and lower sections of the U-shaped rod 29 are located above and below the turntable 2, respectively. A first feeding plate 30 is fixedly connected to the upper end of the U-shaped rod 29, and a second feeding plate 31 is fixedly connected to the lower end of the U-shaped rod 29. A racetrack-shaped connecting rod 32 is also fixedly connected to the lower end of the U-shaped rod 29, and the connecting rod 32 is fixedly attached to the lower end of the extrusion plate 6. The turntable 2 transfers the cigarette holder 1 from station 4 10 to station 5 11 for feeding the cigarette holder 1. The component works in conjunction with the positioning component. When the first cylinder 5 pushes the extrusion plate 6 to press the mouthpiece 1 into the mounting groove 4, the extrusion plate 6 drives the connecting rod 32 to move towards the fifth station 11. The connecting rod 32 drives the U-shaped rod 29 to move. The upper and lower rods of the U-shaped rod 29 respectively drive the first feeding plate 30 and the second feeding plate 31 to approach and press on the mouthpiece 1, pushing the mouthpiece 1 at the fifth station 11 away from the turntable 2, thus realizing the feeding of the mouthpiece 1. The cooperation between the feeding component and the positioning component realizes the linkage between the components and can reduce the investment of additional power sources.

[0042] Reference Figure 6 The lower surface of the horizontal plate 13 is fixed with conical rubber tubes 33 on both sides. The flared end of the rubber tube 33 faces downward and is sleeved on the outer ring of the hollow tube. During the process of spraying glue into the groove by inserting the nozzle 16, the lower end of the rubber tube 33 covers the groove and covers the glue to prevent the glue from splashing out and contaminating the mouthpiece 1.

[0043] Reference Figure 1A drying component is also provided between the glue spraying component and the feeding component. The drying component includes a fan blade driven by a motor, and an air guide shroud 34 is provided on the outside of the fan blade. The air guide shroud 34 is used to guide the air into the groove. The glue is applied to the groove by spraying, and the glue used has good fluidity, which also makes it solidify slowly. In order to accelerate the adhesion speed between the glue and the iron block 3, the drying component is set up. The fan blade pushes the air into the groove to dry part of the glue in the groove. After the iron block 3 is embedded in the groove later, the glue can quickly solidify and adhere to the iron block 3, so as to achieve rapid adhesion of the iron block 3.

[0044] Reference Figure 8 The rotating plate 20 is equipped with a pressure relief assembly. The pressure relief assembly includes a base block 35, a branch pipe 22 that is disconnected at the middle position, the disconnected end of the branch pipe 22 extending into the interior of the base block 35, and a sliding hole 36 at the middle position of the base block 35, which extends to the lower surface of the rotating plate 20. A pressure relief rod 37 is provided in the sliding hole 36. A channel 371 is opened on the outer ring of the upper end of the pressure relief rod 37, and a pressure relief hole 38 with an "I"-shaped cross-section is opened on the lower half of the pressure relief rod 37. The lower end of the pressure relief rod 37 is connected to the lower surface of the rotating plate 20 by a compression spring. A support plate 39 is provided below the rotating plate 20, and the support plate 39 is set close to the turntable 2. In order to ensure that the iron block 3 can be placed stably in the groove, a pressure relief assembly is provided on the branch pipe 22. When the rotating plate 20 moves downward, the disconnected branch pipe 22 is first connected through the channel 371, and then the rotating plate 20 continues to move downward. The lower end of the pressure relief rod 37 presses against the support plate 39. At this time, the pressure relief rod 37 gradually moves upward relative to the base block 35, and the channel 371 gradually shifts away from the break in the branch pipe 22. At this time, the suction cup 21 has placed the iron block 3 at the groove opening. The rotating plate 20 continues to move downward, and the suction cup 21 pushes the iron block 3 to the bottom of the groove. The break in the branch pipe 22 connects with the pressure relief hole 38. At this time, the suction cup 21 loses the negative pressure environment and no longer adsorbs the iron block 3. Then the rotating plate 20 moves upward to reset. During the reset process, the suction cup 21 has moved away from the iron block 3. At the same time, the pressure relief rod 37 moves downward relative to the base block 35, and the channel 371 connects with the branch pipe 22 again. The suction cup 21 restores the negative pressure environment again. The setting of this pressure relief component allows the suction cup 21 to intermittently achieve a negative pressure environment, thereby controlling the adsorption of the iron block 3 and enabling the iron block 3 to be stably embedded in the groove.

[0045] Reference Figure 3 Each of the mounting slots 4 has a flared edge facing outwards; the shape of the mounting slot 4 increases the entrance, making it easier to embed the mouthpiece 1 into it.

[0046] Working principle: In this embodiment, a high-efficiency electronic cigarette production and assembly equipment is provided. The mouthpieces 1 of the electronic cigarette are placed one by one on the transfer unit. Then, the transfer unit is rotated clockwise to the side of the positioning component, which is also below the glue spraying component. At this time, the positioning component pushes the mouthpiece 1 to accurately install the mouthpiece 1 on the transfer unit. Then, the glue spraying component sprays liquid glue into the groove on the mouthpiece 1. Then, the transfer unit rotates clockwise again to push the mouthpiece 1 to the feeding component. Then, the feeding component accurately transfers the iron block 3 into the groove. Then, the transfer unit rotates clockwise again to transfer the mouthpiece 1 to the bottom of the pressing component. The pressing component further presses the iron block 3 into the groove to improve the firmness of the iron block 3. Then, the transfer unit rotates clockwise again to transfer the mouthpiece 1 to the unloading component. The unloading component, in conjunction with the action of the positioning component, not only realizes the accurate installation of the new mouthpiece 1 on the transfer unit, but also realizes the unloading action of the assembled mouthpiece 1.

[0047] In the process of the transfer unit, the electronic cigarette production and assembly equipment passes through each component in sequence to realize the positioning of mouthpiece 1, glue spraying, iron block 3 assembly, iron block 3 fixing and pressing, and mouthpiece 1 unloading. Each environment does not affect each other. Compared with manual assembly, it is more efficient and has a lower defect rate.

[0048] Turntable 2 is driven by a motor. Assume turntable 2 has n mounting slots 4. Turntable 2 rotates intermittently by 360 / n° each time. The area between the feeding assembly and the glue spraying assembly is designated as station 1 (station 7). The position on turntable 2 opposite the glue spraying assembly is designated as station 2 (station 8). The position on turntable 2 opposite the feeding assembly is designated as station 3 (station 9). The position on turntable 2 opposite the pressing assembly is designated as station 4 (station 10). The position on turntable 2 opposite the feeding assembly is designated as station 5 (station 11). Turntable 2 rotates, transferring cigarette nozzles 1. Cigarette nozzles 1 pass sequentially through stations 1 (station 7), 2 (station 8), 3 (station 9), 4 (station 10), and 5 (station 11). At station 7, the cigarette nozzle 1 is fed into the mounting slot 4. Then, the turntable 2 rotates and transfers the cigarette nozzle 1 to station 8 for pressing. This is to prevent the cigarette nozzle 1 from not being fully assembled into the mounting slot 4 when it was fed at station 7, which would affect the accuracy of the glue spraying and the placement of the iron block 3. When the cigarette nozzle 1 is transferred to station 8, the positioning component is driven first. The cylinder 5 pushes the extrusion plate 6, which extrudes the cigarette nozzle 1 and presses it into place. After the position of the cigarette nozzle 1 is determined, the cylinder 5 drives the extrusion plate 6 to retract and reset, and then the glue spraying component is executed.

[0049] The iron block 3 needs to be glued to the groove on the mouthpiece 1 to ensure the firmness between the iron block 3 and the mouthpiece 1, thereby ensuring the stability between the mouthpiece 1 and the electronic cigarette body. The glue spraying process is as follows: first, the second cylinder 12 is driven to lower the hollow tube, and the nozzle 16 moves into the groove. Then, the external pump head injects glue into the hollow tube and sprays it out from the nozzle 16 onto the surface of the groove. In this embodiment, to ensure the uniformity of the amount of glue sprayed, it is recommended to use a peristaltic pump. The size design of the nozzle 16 is also to ensure that the nozzle 16 can extend into the groove before spraying glue, so as to prevent glue from being sprayed outside the groove and contaminating the mouthpiece 1.

[0050] The servo motor rotates alternately in both forward and reverse directions, thereby driving the rotating plate 20 to rotate alternately in both directions. When the feeding component is in operation, the turntable 2 rotates the glue-sprayed mouthpiece 1 to position 9 of station number 3. The output end of cylinder number 3 presses down on the rotating plate 20. The suction cup 21 on the rotating plate 20, which is close to the turntable 2, adsorbs the iron block 3. The iron block 3 gradually approaches the groove on the mouthpiece 1 below it. Finally, the iron block 3 is lowered and pushed into the groove, and the glue adheres the iron block 3 to the groove. At the same time, the suction cup 21 at the end of the rotating plate 20 away from the turntable 2 moves down and approaches the iron block 3 on the guide rail 26, adsorbing the iron block 3. Then, cylinder number 3 drives the rotating plate 20 to move up and reset. The adhesive force of the glue is greater than that of the suction cup 21. The suction cup 21 adsorbs the iron block 3, so during the upward movement of the rotating plate 20, the suction cup 21 will not carry the iron block 3 away from the groove. Then the rotating plate 2 rotates, moving the mouthpiece 1 equipped with the iron block 3 from station 9 to station 10. At the same time, the servo motor drives the rotating plate 20 to rotate 180 degrees forward / reverse through the engagement of the active tooth 25 and the driven tooth 24. At this time, the suction cup 21 with the iron block 3 moves to the top of the mouthpiece 1 that has just entered station 9. Then the above actions are repeated. The structural design of this feeding component can achieve accurate assembly of the iron block 3 while reducing the preparation time of the iron block 3. During the feeding time of the iron block 3, a new iron block 3 is picked up and prepared, and the interval time is reused.

[0051] As mentioned above, the suction cup 21 pushes the iron block 3 into the groove, and then the suction cup 21 moves upward. At this time, the inside of the suction cup 21 is always in a negative pressure state. Even if the suction cup 21 is not enough to pick up the iron block 3 in the groove and lift it away from the groove, it will still affect the position between the iron block 3 and the groove. The iron block 3 may be dragged and suspended in the groove. The iron block 3 is not accurately assembled in the groove. For this reason, a pressing component is set up. The turntable 2 transfers the cigarette holder 1 from station 9 to station 10. During the process of the cylinder 17 driving the turntable 20 to move downward, it also drives the extension plate 27 to move downward. The extension plate 27 drives the lower end of the pressure rod 28 to approach the iron block 3 at station 10. The lower end of the pressure rod 28 presses down on the iron block 3 and presses the iron block 3 to the bottom of the groove to ensure that the iron block 3 is installed in place.

[0052] Turntable 2 transfers the cigarette holder 1 from station 4 10 to station 5 11 for unloading the cigarette holder 1. The unloading component works in conjunction with the positioning component. When cylinder 1 5 pushes the extrusion plate 6 to press the cigarette holder 1 into the mounting groove 4, the extrusion plate 6 drives the connecting rod 32 to move towards station 5 11. The connecting rod 32 drives the U-shaped rod 29 to move. The upper and lower parts of the U-shaped rod 29 respectively drive the first unloading plate 30 and the second unloading plate 31 to approach and press on the cigarette holder 1, pushing the cigarette holder 1 at station 5 11 away from the turntable 2, thus unloading the cigarette holder 1. The cooperation between the unloading component and the positioning component realizes the linkage between the components and can reduce the investment of additional power sources.

[0053] During the process of spraying glue into the groove through the rubber tube 33, the lower end of the rubber tube 33 covers the groove to cover the glue and prevent the glue from splashing out and contaminating the mouthpiece 1. The glue is applied to the groove by spraying, and the glue used has good fluidity, which also makes it solidify slowly. In order to speed up the adhesion speed between the glue and the iron block 3, a drying component is set up. The fan blade pushes the air into the groove to dry part of the glue in the groove. After the iron block 3 is embedded in the groove later, the glue can quickly solidify and adhere to the iron block 3, so that the iron block 3 can be quickly adhered.

[0054] To ensure that the iron block 3 can be placed stably in the groove, a pressure relief assembly is installed on the branch pipe 22. As the rotating plate 20 moves downwards, the disconnected branch pipe 22 is first reconnected through the channel 371. Then, as the rotating plate 20 continues to move downwards, the lower end of the pressure relief rod 37 presses against the support plate 39. At this time, the pressure relief rod 37 gradually moves upwards relative to the base block 35, and the channel 371 gradually shifts away from the disconnection point of the branch pipe 22. At this point, the suction cup 21 has already placed the iron block 3 at the opening of the groove. As the rotating plate 20 continues to move downwards, the suction cup 21 pushes the iron block 3 into the groove. At the bottom, the branch pipe 22 disconnects and connects to the pressure relief hole 38. At this time, the suction cup 21 loses its negative pressure environment and no longer adsorbs the iron block 3. Then the rotating plate 20 moves up to reset. During the reset process, the suction cup 21 has moved away from the iron block 3. At the same time, the pressure relief rod 37 moves down relative to the base block 35, and the channel 371 connects to the branch pipe 22 again. The suction cup 21 restores its negative pressure environment. The setting of this pressure relief component allows the suction cup 21 to intermittently achieve a negative pressure environment, thereby controlling the adsorption of the iron block 3 and enabling the iron block 3 to be stably embedded in the groove.
