Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic cigarette packaging, and particularly relates to an electronic cigarette automatic packaging line. BACKGROUND

[0002] With the increasing variety of electronic cigarette products, different types of packaging boxes differ in height. The existing electronic cigarette automatic packaging production line is usually a special device, which is usually only suitable for packaging operations of a fixed specification product. When the product of a different height is replaced, the conveying, positioning, boxing and packaging mechanisms of the packaging line need to be manually adjusted or the components need to be replaced to adapt to the size requirements of the new height. This process is complex and has a long changeover period, which reduces production efficiency, increases downtime and thus increases production costs. SUMMARY

[0003] The main purpose of the present application is to provide an electronic cigarette automatic packaging line, which aims to improve the compatibility of the electronic cigarette automatic packaging line, shorten the equipment changeover time, reduce downtime adjustment, and thus reduce production costs.

[0004] To achieve the above-mentioned purpose, the electronic cigarette automatic packaging line provided by the present application comprises:

[0005] a first conveying module;

[0006] a first carrier movably arranged in the first conveying module, the first carrier being provided with a first material placing position for placing electronic cigarettes, a second material placing position for placing inner boxes, a third material placing position for placing packaging boxes, and a buffer position; the first carrier is further formed with a first accommodating groove, the groove bottom of the first accommodating groove is formed with a second accommodating groove, and the first accommodating groove and the second accommodating groove are both used for accommodating labels;

[0007] a printing module for printing labels, the printed labels being used for conveying into the first accommodating groove or the second accommodating groove of the first carrier;

[0008] a pad block detachably connected with the first carrier and selectively installed on the third material placing position or the buffer position, the pad block being used for compensating the height of the packaging box when the pad block is arranged on the third material placing position.

[0009] In an embodiment, one of the first carrier and the pad block is provided with a positioning pin, and the other is provided with a positioning hole for inserting the positioning pin.

[0010] In an embodiment, the pad block is magnetically connected with the first carrier.

[0011] In an embodiment, the first conveying module has a first label placing position, and the electronic cigarette automatic packaging line further comprises a feeding module, which is movable between an end of the printing module and the first label placing position to transfer the printed label to the first carrier located at the first label placing position. The feeding module comprises an air supply module and a first label suction head, and the first label suction head is detachably connected to the air supply module. The first label suction head is configured to pick up the label by negative pressure adsorption.

[0012] In an embodiment, the air supply module comprises a mounting seat, an elastic member, a buckle and an air pipe. The mounting seat has an air source channel and a movable cavity formed therein and communicating with each other. The air pipe is arranged in the air source channel. The elastic member is movably arranged in the movable cavity and abuts against an inner wall of the movable cavity at one end and against the buckle at the other end. The first label suction head comprises a connecting portion and a label suction portion. The connecting portion is sleeved on the outer periphery of the air pipe and is provided with a first air passage communicating with the air pipe. The label suction portion is provided with a plurality of second air passages communicating with the first air passage. The outlet end of the second air passage faces the adsorption surface of the label suction portion and communicates with the outside. The connecting portion is provided with a clamping groove adapted to be clamped with the buckle.

[0013] In an embodiment, the first conveying module further has a first feeding position located upstream of the first label placing position, a second feeding position and a third feeding position located downstream of the first label placing position in sequence. The first carrier loads the electronic cigarette, the packaging box and the inner box at the first feeding position, loads the charging device and the inner box into the packaging box at the second feeding position, and the inner box covers the charging device.

[0014] The feeding module is further movable to the third feeding position. The feeding module further comprises a first clamping jaw configured to pick up the electronic cigarette from the first placing position of the first carrier at the third feeding position and load the electronic cigarette into the inner box located in the packaging box. After the electronic cigarette is loaded into the inner box, the feeding module transfers the label on the first carrier to the inner box by the first label suction head.

[0015] In an embodiment, the first carrier is provided with a avoiding opening located at the buffer position or between the third placing position and the buffer position. The packaging box comprises a box body and a reversible cover. When the first carrier is located at an upstream work station of the third feeding position, the cover is at least partially located at the buffer position.

[0016] The automatic packaging line for electronic cigarettes also includes a lid-closing module corresponding to the third feeding position. The lid-closing module includes a top cover assembly, a lifting assembly, and a stop assembly. When the first carrier is located at the third feeding position, the lifting assembly is located below the first carrier and is vertically detachable, used to lift the first carrier and detach it from the first conveying module.

[0017] The stop assembly is located at the front end of the first carrier along the conveying direction and is used to stop the first carrier; the top cover assembly is located on the side of the first carrier opposite to the stop assembly, and the top cover assembly includes a liftable top block that can pass through the clearance opening and push the cover upward, so that the cover flips over and closes onto the box body.

[0018] In one embodiment, the first conveying module includes two parallel extending conveyor lines and two transfer modules. The loading end of one of the conveyor lines and the unloading end of the other conveyor line are located on the same side of the electronic cigarette automatic packaging line. The two transfer modules are respectively disposed in the loading and unloading areas of the two conveyor lines and can move in a direction perpendicular to the extension direction of the conveyor lines to transfer the first carrier between the two conveyor lines. The first loading position, the first label placement position, and the second loading position are sequentially arranged from the loading end to the unloading end of one of the conveyor lines, and the third loading position is disposed on the other conveyor line.

[0019] In one embodiment, the automatic electronic cigarette packaging line further includes a second conveying module, a first detection module, a lid opening module, and a label picking module. The second conveying module is located downstream of the first conveying module. The first detection module is used to detect the appearance of the packaging box. The lid opening module is located downstream of the first detection module. The lid opening module includes a second gripper, a first rotating assembly, and a mounting plate connected to the first rotating assembly. The mounting plate is provided with multiple vacuum suction cups. The second gripper is used to clamp the packaging box. The first rotating assembly can move up and down and can drive the mounting plate to rotate to open or close the lid of the packaging box.

[0020] The automatic packaging line for electronic cigarettes also includes a second carrier, which has a fourth feeding position for placing the packaging box and a fifth feeding position for placing the label. When the opening module opens the lid of the packaging box, the label picking module is used to take out the label from the inner box and transfer it to the fifth feeding position.

[0021] In one embodiment, the automatic packaging line for electronic cigarettes further includes a buffer station, a labeling module, and a second detection module. The buffer station is located downstream of the second conveying module and is used to buffer the second carrier. The labeling module is used to pick up the label located on the second carrier, transfer the label, and affix it to the outer surface of the packaging box located on the second carrier. The second detection module is located downstream of the labeling module and is used to detect the appearance of the packaged box after labeling.

[0022] In one embodiment, the automatic packaging line for electronic cigarettes further includes a label peeling module and a waste container. The label peeling module includes a label peeling platform and label peeling grippers. The label peeling platform is used to hold the label to be peeled off. The label includes an overlapping body layer and a release liner layer. The release liner layer protrudes from the edge of the label peeling platform. The label peeling grippers are used to hold the protruding portion of the release liner layer. The labeling module includes a second label suction head for adsorbing the body layer. When the release liner layer is held and fixed by the label peeling grippers, the second label suction head peels the body layer from the release liner layer by relative movement. The waste container is provided with a receiving port, through which the peeled release liner layer is collected.

[0023] The technical solution of this invention utilizes a detachable pad block installed at the third feeding position of the first carrier, which can flexibly compensate for the dimensional differences of packaging boxes of different heights. When changing the packaging box model, only the pad block needs to be replaced or added / removed, flexibly matching different products and improving the equipment's versatility. It eliminates the need for complex mechanical adjustments to downstream mechanisms such as conveying, positioning, and boxing, effectively solving the limitation of traditional dedicated equipment being limited to one model per machine. This significantly improves the adaptability of the automatic e-cigarette packaging line to e-cigarette packaging boxes of different heights. The pad block structure of this invention is simple, easy to install and remove, and the model change operation is simple and quick, achieving minute-level switching. This avoids the cumbersome parameter calibration and component replacement processes of traditional methods, greatly shortening changeover time and reducing equipment downtime, thereby improving production line utilization and production efficiency, and ultimately reducing production costs caused by changeover downtime.

[0050] This invention proposes an automated packaging line for electronic cigarettes.

[0051] Please see Figures 1 to 6 , Figure 10 In one embodiment of the present invention, the automatic packaging line for electronic cigarettes includes a first conveying module 10, a first carrier 11, a printing module 13, and a pad 12. The first carrier 11 is movably disposed on the first conveying module 10. The first carrier 11 has a first feeding position 111 for placing electronic cigarettes, a second feeding position 112 for placing inner boxes, a third feeding position 113 for placing packaging boxes 24, and a buffer position 114. The first carrier 11 also forms a first receiving groove 115. The bottom has a second receiving groove 116, and both the first receiving groove 115 and the second receiving groove 116 are used to receive the label 25; the printing module 13 is used to print the label 25, and the printed label 25 is used to be conveyed to the first receiving groove 115 or the second receiving groove 116 of the first carrier 11; the pad block 12 is detachably connected to the first carrier 11 and can be selectively installed in the third feeding position 113 or the buffer position 114. When the pad block 12 is set in the third feeding position 113, the pad block 12 is used to compensate for the height of the packaging box 24.

[0052] Specifically, the first conveying module 10 includes a conveyor line and a conveyor belt mounted on the conveyor line, the conveyor belt being rotatable relative to the conveyor line. A first carrier 11 is mounted on the first conveying module 10. Under the action of the conveyor belt, the first carrier 11 can move relative to the conveyor line, thus sequentially passing through each workstation along the conveying direction of the first conveying module 10. The first carrier 11, as a multi-functional carrying platform, integrates multiple functional areas for integrating and synchronously conveying various materials such as e-cigarettes, inner boxes, packaging boxes 24, and labels 25. Specifically, the first placement position 111 is used to place the e-cigarette product to be packaged, the second placement position 112 is used to place the inner box (i.e., the small box containing the e-cigarette), the third placement position 113 is used to place the packaging box 24, and the buffer position 114 serves as a spare position for storing auxiliary components (such as pads 12). When the cover 242 of the packaging box 24 is opened, the buffer position 114 can also be used to temporarily place the cover 242.

[0053] Furthermore, the first carrier 11 is also provided with a first receiving slot 115, and a second receiving slot 116 is further provided at the bottom of the first receiving slot 115. In use, the first receiving slot 115 of the first carrier 11 is located above the second receiving slot 116, and the length and / or width of the first receiving slot 115 is greater than that of the second receiving slot 116. That is, the first receiving slot 115 is used to accommodate labels 25 with greater length and / or width, and the second receiving slot 116 is used to accommodate labels 25 with smaller length and / or width, ensuring the orderly positioning and accurate retrieval of the labels 25 during transport. This double-layer slot design of the first receiving slot 115 and the second receiving slot 116 not only supports the storage of labels 25 of different types or sizes to enhance the compatibility of the first carrier 11, but the recessed design of the second receiving slot 116 also saves space occupied by the second receiving slot 116, thereby facilitating the miniaturization of the first carrier 11.

[0054] The printing module 13 is used to print labels 25 on-site, such as personalized information like QR codes, batch numbers, and barcodes. The printed labels 25, depending on their specifications, are temporarily stored in either the first receiving slot 115 or the second receiving slot 116 of the first carrier 11, awaiting subsequent labeling operations. The printing module 13 enables online customized printing and precise delivery of labels 25, avoiding inventory pressure and misuse risks associated with pre-printed labels 25.

[0055] The pad block 12, as a height compensation structural component, is detachably connected to the first carrier 11. The pad block 12 can be selectively installed at the third discharge position 113 or the buffer position 114. (See also...) Figure 5 and Figure 6When the height of the packaging box 24 is relatively small, the pad 12 is installed at the third feeding position 113. In this case, the pad 12 acts as a height compensation structure to raise the overall height of the packaging box 24, ensuring that the overall height of the packaging box 24 matches the standard specifications. This adapts to the working parameters of downstream automated equipment (such as gripping robots, sealing mechanisms, etc.), thereby ensuring that subsequent processes such as boxing, pushing, and sealing can operate normally without adjusting equipment parameters. Please refer to [link to relevant documentation]. Figure 3 and Figure 4 When the height of the packaging box 24 is large, the packaging box 24 does not need to be height compensated, and the pad block 12 is installed in the buffer position 114 and is in an idle state.

[0056] By detachably installing the pad 12 at the third feeding position 113 of the first carrier 11, the size difference of packaging boxes 24 of different heights can be flexibly compensated. When changing the model of packaging box 24, only the corresponding pad 12 needs to be replaced or added to quickly adapt to different specifications of products, significantly improving the versatility of the equipment. Compared with traditional automatic packaging equipment for electronic cigarettes, which requires complex mechanical adjustments or component replacements for multiple downstream mechanisms such as conveying, positioning, boxing, and sealing, this invention only needs to switch the installation state of the pad 12 to make packaging boxes 24 of different heights at the same height benchmark, effectively solving the limitation of traditional dedicated equipment being one machine per type, and greatly enhancing the adaptability of the packaging line to electronic cigarette packaging boxes 24 of different heights.

[0057] The pad 12 of this invention has a simple structure and is easy to assemble and disassemble, making changeover operations simple and quick, achieving minute-level switching. This avoids the cumbersome parameter calibration, tool replacement, and manual debugging processes of traditional methods, significantly shortening changeover time, reducing equipment downtime and losses, and improving production line utilization and efficiency, thereby reducing production costs caused by frequent changeovers. Simultaneously, the pad 12 has good versatility, eliminating the need for customized special parts, reducing reliance on highly skilled technicians, and lowering maintenance difficulty and operating costs.

[0058] Furthermore, packaging boxes 24 of different heights typically correspond to different label sizes 25 in practical applications. Larger packaging boxes 24 require larger labels 25, while shorter packaging boxes 24 require smaller labels 25. This invention achieves compatibility and adaptation for label sizes corresponding to packaging boxes 24 of different heights by providing a first receiving slot 115 and a second receiving slot 116 of different sizes on the first carrier 11. Specifically, the first receiving slot 115 is used to store larger labels 25 suitable for taller packaging boxes 24, while the second receiving slot 116 is used to store smaller labels 25 suitable for shorter packaging boxes 24.

[0059] Specifically, when the packaging line switches to a taller packaging box 24, the printing module 13 prints a large label 25 according to instructions and temporarily stores it in the first receiving slot 115 of the first carrier 11; when switching to a shorter packaging box 24, the printing module 13 prints a small label 25 according to instructions and temporarily stores it in the second receiving slot 116 of the first carrier 11. This layered, sized label 25 storage and supply design ensures that labels 25 of different sizes are matched with packaging boxes 24 of different sizes.

[0060] Furthermore, the label 25 adaptation mechanism works in conjunction with the height compensation function of the pad 12. The pad 12 is used to unify the external physical reference height of packaging boxes 24 of different heights during the conveying process, ensuring stable operation of downstream automated mechanisms under unified workstation conditions. At the same time, the first receiving slot 115 and the second receiving slot 116 of different sizes adapt to the label 25 specifications required by packaging boxes 24 of different heights, which not only improves the flexibility and accuracy of label 25 supply, but also enhances the intelligence level of the electronic cigarette automated packaging line when combined with the height compensation mechanism.

[0061] The technical solution of the present invention integrates a first conveying module 10, a first carrier 11, a printing module 13, and a detachable pad 12, which enables rapid adaptation to packaging boxes 24 of different heights. This avoids the cumbersome operations of frequent machine downtime, component replacement, or manual adjustment in traditional equipment. It effectively solves the problems of poor compatibility and complex changeover adjustments of existing packaging equipment when dealing with packaging boxes 24 of different heights, thereby shortening equipment changeover time, reducing downtime for adjustments, and lowering production costs.

[0062] In one embodiment, one of the first carrier 11 and the pad 12 is provided with a positioning pin, and the other is provided with a positioning hole for the positioning pin to be inserted.

[0063] A mutually cooperating positioning structure is provided between the first carrier 11 and the pad 12. One structure has a positioning pin, and the other has a corresponding positioning hole. This allows the pad 12 to be quickly and accurately assembled when installed at the third feeding position 113 or buffer position 114 of the first carrier 11, by inserting the positioning pin into the positioning hole, ensuring the consistency and repeatability of its installation position. This positioning structure not only simplifies the installation process for operators and avoids inaccurate packaging height compensation due to misalignment of the pad 12, thus affecting the reliability of subsequent automatic boxing, but also helps improve the stability of equipment operation and the yield rate of packaged products. Furthermore, the pin-hole positioning structure is compact and easy to assemble and disassemble, facilitating rapid changeovers during the switching of different product specifications on the packaging line.

[0064] In other embodiments, one of the first carrier 11 and the pad 12 may be provided with a positioning groove, and the other may be provided with a positioning protrusion.

[0065] In one embodiment, the pad 12 is magnetically connected to the first carrier 11.

[0066] Magnetic elements that attract each other can be provided at the mating points of the pad 12 and the first carrier 11. For example, magnets can be embedded in the third feeding position 113 and the buffer position 114 of the first carrier 11, while ferromagnetic materials or magnets of opposite polarity can be provided at corresponding positions on the pad 12, thereby achieving magnetic attraction and fixation between the two. This magnetic connection structure ensures that the pad 12 is securely installed, while allowing operators to quickly disassemble and reinstall the pad 12 when changing product specifications without the need for tools or complex locking operations, significantly improving the efficiency of equipment changeover.

[0067] Furthermore, combined with the aforementioned positioning pin and positioning hole structure, the magnetic connection not only provides reliable fixing force to prevent the pad 12 from shifting due to vibration or impact during transportation, but also works in synergy with the positioning structure to achieve the dual effects of rapid alignment and firm fixation. It combines mechanical stability and operational flexibility, effectively ensuring the continuous and stable operation of the packaging line when frequently switching between different packaging box heights 24, and further shortening downtime for adjustment.

[0068] In other embodiments, the pad 12 and the first carrier 11 are detachably connected by snap-fit ​​or bolt fastening.

[0069] In one implementation, please refer to Figure 7 and Figure 10 The first conveying module 10 has a first label placement position. The electronic cigarette automatic packaging line also includes a feeding module 14. The feeding module 14 can move between the label outlet end of the printing module 13 and the first label placement position to transfer the printed label 25 to the first carrier 11 located at the first label placement position. The feeding module 14 includes an air source module 141 and a first label suction head 142. The first label suction head 142 is detachably connected to the air source module 141 and is used to pick up the label 25 by negative pressure adsorption.

[0070] The first conveying module 10 is equipped with a first label placement position for positioning the first carrier 11, ensuring precise alignment with the label 25 feeding process and guaranteeing that the label 25 can be accurately placed in the first receiving slot 115 or the second receiving slot 116 of the first carrier 11. To achieve automated transfer of the label 25, the packaging line is also equipped with a feeding module 14. The feeding module 14 has the ability to reciprocate between the label output end of the printing module 13 and the first label placement position, thereby efficiently and accurately conveying the printed label 25 to the target location. Specifically, the feeding module 14 includes an air source module 141 and a first label suction head 142, wherein the first label suction head 142 is detachably connected to the air source module 141 for easy maintenance, replacement, or adaptation to labels 25 of different sizes. During operation, the air source module 141 provides negative pressure, enabling the first label suction head 142 to stably pick up the labels 25 output by the printing module 13 via vacuum adsorption. After moving to the first label placement position, the negative pressure is released to precisely place the label 25 into the corresponding receiving slot of the first carrier 11. This negative pressure adsorption method has the advantages of reliable pickup, minimal damage to the label 25, and adaptability to labels 25 of various materials, improving the stability and positioning accuracy of label 25 transmission. Simultaneously, the feeding module 14, using the negative pressure adsorption method of the first label suction head 142, can accommodate labels 25 of both sizes.

[0071] In other embodiments, the feeding module 14 may also pick up the label 25 in other ways, such as by using a gripper.

[0072] In one implementation, please refer to Figure 8 and Figure 9 The air source module 141 includes a mounting base 1411, an elastic element 1412, a buckle 1413, and an air pipe 1414. The mounting base 1411 has an intersecting air source channel 14111 and a movable cavity 14112. The air pipe 1414 is located within the air source channel 14111. The elastic element 1412 is movably located within the movable cavity 14112, with one end abutting against the inner wall of the movable cavity 14112 and the other end abutting against the buckle 1413. The first label suction head 142 includes... The connecting part 1421 and the label-absorbing part 1422 are provided. The connecting part 1421 is sleeved on the outer periphery of the air tube 1414 and has a first airway 14211 communicating with the air tube 1414. The label-absorbing part 1422 has a plurality of second airways 14221 communicating with the first airway 14211. The outlet end of the second airway 14221 faces the adsorption surface of the label-absorbing part 1422 and communicates with the outside. The outer periphery of the connecting part 1421 is provided with a slot 14212 that is adapted to engage with the buckle 1413.

[0073] The mounting base 1411 is an integral support structure, internally equipped with an air source channel 14111 and a movable chamber 14112. The air source channel 14111 accommodates and fixes the air pipe 1414, which connects to an external vacuum generator (such as a vacuum pump) to provide negative pressure airflow. The movable chamber 14112 intersects and communicates with the air source channel 14111, and contains an elastic element 1412 and a latch 1413, forming a retractable locking mechanism. One end of the elastic element 1412 abuts against the inner wall of the movable chamber 14112, and the other end abuts against the latch 1413, causing it to pop outward in the normal state, forming a locking ready state. The latch 1413 can slide within the movable chamber 14112 and tends to extend outward under the action of the elastic element 1412, for quick locking with the slot 14212 on the first label suction head 142. The first label suction head 142 includes a connecting part 1421 and a label suction part 1422. The connecting part 1421 is sleeved on the outer periphery of the air tube 1414 and has a first airway 14211 inside. The first airway 14211 is connected to the air tube 1414 and is used to conduct negative pressure. The label suction part 1422 is located below the connecting part 1421 and has multiple branch airways, namely second airways 14221. The second airways 14221 are connected to the first airways 14211 and transmit their negative pressure to the adsorption surface. The outlet end of the second airway 14221 is distributed on the adsorption surface of the label suction part 1422 and is connected to the outside, forming a uniformly distributed negative pressure area to ensure stable adsorption and flat pickup of the label 25 at multiple points, and to avoid the label 25 from being skewed, wrinkled or falling off due to single-point adsorption.

[0074] During assembly, as the first suction head 142 is pushed in, the latch 1413 is compressed by the elastic element 1412. When the slot 14212 is aligned, the latch 1413 automatically springs into the slot 14212 under the restoring force of the elastic element 1412, achieving a quick and reliable locking. This structure not only ensures the airtightness of the air circuit connection, preventing air leakage from causing a decrease in adsorption force, but also enables the plug-and-play installation of the first suction head 142, facilitating quick switching between different suction heads or cleaning and maintenance.

[0075] In one implementation, please refer to Figure 7 and Figure 10The first conveying module 10 also has a first loading position located upstream of the first label placement position, a second loading position located downstream of the first label placement position, and a third loading position. The first carrier 11 loads the electronic cigarette, the packaging box 24, and the inner box at the first loading position. At the second loading position, the charging device and the inner box are placed into the packaging box 24, and the inner box is placed above the charging device. The loading module 14 can also move to the third loading position. The loading module 14 also includes a first gripper 143, which is used to pick up the electronic cigarette from the first loading position 111 of the first carrier 11 and put it into the inner box located in the packaging box 24. After the electronic cigarette is put into the inner box, the loading module 14 transfers the label 25 on the first carrier 11 to the inner box through the first label suction head 142.

[0076] The first conveying module 10 is sequentially equipped with a first loading position, a first label placement position, a second loading position, and a third loading position along the conveying direction. At the first loading position, the operator or the automatic loading mechanism places the electronic cigarette, inner box, and packaging box 24 into the first loading position 111, the second loading position 112, and the third loading position 113 of the first carrier 11, respectively, completing the initial material loading. Subsequently, the first carrier 11 is conveyed to the first label placement position. At this position, the loading module 14 picks up the printed label 25 from the label output end of the printing module 13 and accurately transfers the label 25 into the first receiving slot 115 or the second receiving slot 116 of the first carrier 11 using a negative pressure adsorption method through the first label suction head 142, realizing the online preparation of the label 25. Then, the first carrier 11 enters the second loading position for preliminary assembly operations. At this workstation, the charging device (such as a charging head and data cable, or other types of charging equipment) is first placed into the packaging box 24, and then the inner box is placed on top of the charging device, so that the inner box is placed in a way that covers the charging device, forming a pre-assembled structure inside the packaging box 24. Subsequently, the first carrier 11 continues to transport to the third loading station, where the loading module 14 performs the core assembly action. The loading module 14 is not only equipped with a first label suction head 142, but also integrates a first gripper 143, which has multi-degree-of-freedom operation capability. The first gripper 143 can accurately pick up the e-cigarette from the first unloading position 111 of the first carrier 11 and put it into the inner box already placed in the packaging box 24, completing the loading of the e-cigarette body. After the e-cigarette is put into the inner box, the loading module 14 immediately switches functions, using the first label suction head 142 to pick up the pre-placed label 25 from the corresponding receiving slot of the first carrier 11 and transfer it to the inside of the inner box or the designated position of the e-cigarette.

[0077] In one implementation, please refer to Figure 1 and Figure 2 , Figure 11 and Figure 12The first carrier 11 has a clearance opening 117, which is located at the buffer position 114, or between the third feeding position 113 and the buffer position 114. The packaging box 24 includes a box body 241 and a flip-out lid 242. When the first carrier 11 is located upstream of the third feeding position, the lid 242 is at least partially located at the buffer position 114. The automatic electronic cigarette packaging line also includes a lid closing module 15 corresponding to the third feeding position. The lid closing module 15 includes a top cover assembly 151, a lifting assembly 152, and a stop assembly 153. When the first carrier 11 is located upstream of the third feeding position, the lid 242 is at least partially located at the buffer position 114. When the material is loaded at the third position, the lifting component 152 is located below the first carrier 11 and is vertically adjustable to lift the first carrier 11 and detach it from the first conveying module 10; the stop component 153 is located at the front end of the first carrier 11 along the conveying direction to stop the first carrier 11; the top cover component 151 is located on the side of the first carrier 11 opposite to the stop component 153, and the top cover component 151 includes a vertically adjustable top block 1511, which can pass through the clearance opening 117 and push the cover 242 upward, so that the cover 242 flips over and covers the box body 241.

[0078] The first vehicle 11 has an obstacle clearance 117, please refer to Figure 1 The clearance port 117 can be set in buffer bit 114; please refer to Figure 2 The clearance opening 117 can also be located between the third feeding position 113 and the buffer position 114, its function being to provide the necessary space channel for the closing action. The packaging box 24 includes a box body 241 and a flip-up lid 242. During the journey of the first carrier 11 from the first feeding position to the third feeding position, the packaging box 24 is always in the open state, so that the charging device, inner box, electronic cigarette, and label 25 can be sequentially loaded into the box body 241 at the corresponding workstation. The open lid 242 is placed in the area where the buffer position 114 is located, which not only utilizes the empty space of the buffer position 114, but also puts it within the range of action of the closing module 15, preparing for subsequent automatic closing.

[0079] Please see Figures 10 to 12The automated e-cigarette packaging line is further equipped with a cap-closing module 15 corresponding to the third loading position. The cap-closing module 15 includes a top cap assembly 151, a lifting assembly 152, and a stop assembly 153, which work together to complete a stable and precise cap-closing action. When the first carrier 11 moves to the third loading position, the stop assembly 153 activates the front end of the first carrier 11 along the conveying direction and stops the first carrier 11. At the same time, the lifting assembly 152 located directly below the first carrier 11 lifts the entire first carrier 11 along with the packaging box 24 on it through a lifting and lowering motion, causing it to detach from the support surface of the first conveying module 10. This prevents the first carrier 11 from continuing to move under the action of the first conveying module 10, allowing the first carrier 11 to stop at the third loading position, facilitating the loading operation of e-cigarettes and labels 25 and the cap-closing operation of packaging boxes 24 at the third loading position. Of course, the first loading position, the first label placement position and the second loading position are also equipped with corresponding lifting components 152 and stop components 153, so that the first carrier 11 can detach from the first module at the corresponding work station and perform corresponding operations, which will not be described in detail here.

[0080] The top cover assembly 151 is located on the side opposite to the first carrier 11 and the stop assembly 153. The top cover assembly 151 includes a liftable top block 1511. When the first carrier 11 is lifted, the top block 1511 rises under the action of the drive mechanism, precisely passes through the clearance opening 117 on the first carrier 11, and pushes upward on the lid 242 of the packaging box 24. Since part of the lid 242 is located in the buffer position 114 at this time, the top block 1511 applies an upward pushing force through the clearance opening 117, causing the lid 242 to flip around its hinge point and finally smoothly close onto the box body 241, completing the automatic closure.

[0081] Furthermore, the top block 1511 includes a first lifting part and a second lifting part. The first lifting part is disposed on the upper surface of the second lifting part, and a stepped surface is formed between them on the side where the front end of the second lifting part is located in the conveying direction. During the lifting process, the first lifting part first contacts the outer side of the cover 242 and pushes the cover 242 to perform a flipping action. As the cover 242 flips, after the cover 242 has flipped 90°, one edge of the cover 242 near the box body 241 falls onto the stepped surface. The top block 1511 continues to rise, and the second lifting part begins to push the cover 242 to continue flipping, so that the cover 242 finally closes onto the box body 241, completing the automatic closing.

[0082] In other embodiments, the lid-closing module 15 may also be located at a station downstream of the third loading station, thereby shortening the time the first carrier 11 stays at the third loading station and thus increasing the production cycle of the packaging line.

[0083] In one implementation, please refer to Figure 10The first conveying module 10 includes two parallel extending conveyor lines 101 and two transfer modules 102. The loading end of one conveyor line 101 and the unloading end of the other conveyor line 101 are located on the same side of the electronic cigarette automatic packaging line. The two transfer modules 102 are respectively arranged in the loading end and unloading end areas of the two conveyor lines 101, and can move in a direction perpendicular to the extension direction of the conveyor line 101 to transfer the first carrier 11 between the two conveyor lines 101. The first loading position, the first label placement position, and the second loading position are arranged sequentially from the loading end to the unloading end of one of the conveyor lines 101, and the third loading position is located on the other conveyor line 101.

[0084] in, Figure 10 The arrows in the diagram indicate the direction of movement of the first carrier 11. The first conveying module 10 includes two parallel conveying lines 101, namely the first conveying line 101a and the second conveying line 101b. The loading end of the first conveying line 101a and the unloading end of the second conveying line 101b are located on the same side of the packaging line. Two transfer modules 102 are respectively arranged in the loading and unloading areas of the two conveying lines 101 and have the ability to move laterally along the direction perpendicular to the extension of the conveying lines 101, so that the first conveying module 10 forms a "U"-shaped layout. The first loading position, the first label placement position, and the second loading position are arranged sequentially along the conveying direction of the first conveying line 101a, and are used to complete the initial loading of electronic cigarettes, inner boxes, and packaging boxes 24, temporary storage of labels 25, and pre-installation of charging devices and inner boxes. The third loading position is arranged on the second conveying line 101b and is used to perform the process of inserting electronic cigarettes and labels 25 into the inner box and the closing operation.

[0085] During operation, the first carrier 11 enters from the loading end of the first conveyor line 101a, sequentially completing the operations at the first loading position, the first label placement position, and the second loading position. Upon reaching the unloading end, it is transferred by the transfer module 102 to the loading end of the second conveyor line 101b. The second conveyor line 101b operates in reverse, transporting the first carrier 11 to its unloading end, during which the assembly and capping tasks at the third loading position are completed. When the first carrier 11 reaches the unloading end of the second conveyor line 101b, another transfer module 102 transfers it back to the loading end of the first conveyor line 101a, achieving a closed-loop recycling of the first carrier 11. This eliminates the need for manual transfer of the first carrier 11, improving the automation level and operational continuity of the production line. Simultaneously, the automatic transfer process is precisely synchronized with the conveying rhythm, achieving seamless connection and ensuring consistent cycle times at each workstation, thus improving overall production efficiency. Combined with the carrier's closed-loop recycling mechanism, the system can operate stably for extended periods without human intervention, enhancing the intelligence and unmanned production level of the e-cigarette packaging line.

[0086] In other embodiments, the first conveying module 10 may also have only one conveying line 101, with the first loading position, the first label placement position, the second loading position and the third loading position arranged sequentially along the conveying direction of the single conveying line 101.

[0087] In one implementation, please refer to Figures 13 to 15 The automated packaging line for electronic cigarettes also includes a second conveying module 16, a first detection module 17, a lid-opening module 18, and a label-taking module 19. The second conveying module 16 is located downstream of the first conveying module 10. The first detection module 17 is used to detect the appearance of the packaging box 24. The lid-opening module 18 is located downstream of the first detection module 17. The lid-opening module 18 includes a second gripper 182, a first rotating assembly 181, and a mounting plate 183 connecting the first rotating assembly 181. The mounting plate 183 is provided with multiple vacuum suction cups 184. 2 is used to clamp the packaging box 24. The first rotating component 181 can move up and down and can drive the mounting plate 183 to rotate to open or close the cover 242 of the packaging box 24. The automatic packaging line for electronic cigarettes also includes a second carrier 20. The second carrier 20 is provided with a fourth feeding position 201 for placing the packaging box 24 and a fifth feeding position 202 for placing the label 25. When the opening module 18 opens the cover 242 of the packaging box 24, the label taking module 19 is used to take out the label 25 in the inner box and transfer it to the fifth feeding position 202.

[0088] The second conveying module 16 is located downstream of the first conveying module 10 and is used to receive the assembled and closed packaging box 24 and stably convey it to the subsequent inspection and opening station. The first inspection module 17 is used to automatically visually inspect the appearance of the packaging box 24, including but not limited to defects such as box printing quality, lid integrity, surface scratches or foreign objects, to realize online product quality judgment, ensure that unqualified products are identified and rejected in a timely manner, and effectively improve the consistency and pass rate of outgoing products.

[0089] Downstream of the first detection module 17, a lid-opening module 18 is provided for opening the sealed packaging box 24 to remove the label 25 inside the packaging box 24 and place it onto the fifth feeding position 202 of the second carrier 20 for subsequent labeling operations. The lid-opening module 18 includes a second gripper 182, a first rotating assembly 181, and a mounting plate 183 connected thereto. The mounting plate 183 integrates multiple vacuum suction cups 184. During operation, the second gripper 182 first clamps the box body 241 of the packaging box 24 to ensure it remains fixed during operation. Then, the first rotating assembly 181 drives the mounting plate 183 to move downward and precisely align it with the lid 242 of the packaging box 24, where the vacuum suction cups 184 adsorb the surface of the lid 242. Next, the first rotating assembly 181 rotates the mounting plate 183 by a certain angle, thereby smoothly opening the flip-top lid 242 of the packaging box 24, exposing the inner box and the internal label 25. The opening module 18 ensures a smooth and reliable opening action by interlocking the clamping of the box body 241, the adsorption of the lid 242, and the rotation of the lid 242, thus preventing damage to the packaging due to excessive force. After the label 25 is removed, the opening module 18 rotates in the opposite direction via the first rotating component 181 to re-close the lid 242 onto the box body 241.

[0090] The automated packaging line for electronic cigarettes is also equipped with a second carrier 20, which has a fourth feeding position 201 and a fifth feeding position 202. The fourth feeding position 201 is used to place the packaging box 24 transferred from the second conveying module 16, and the fifth feeding position 202 is used to place the label 25 removed from the packaging box 24. After the opening module 18 completes the opening of the packaging box 24, the label picking module 19 is immediately activated. It can be equipped with a special gripper or suction head structure to accurately reach into the opened packaging box 24, pick up the label 25 placed in the inner box, and transfer it to the fifth feeding position 202 of the second carrier 20.

[0091] In other embodiments, the electronic cigarette automatic packaging line also includes a first weighing module and a first sampling module arranged sequentially between the downstream of the first conveying module 10 and the upstream of the first detection module 17.

[0092] In one implementation, please refer to Figure 16 The electronic cigarette automatic packaging line also includes a buffer station 21, a labeling module 26, and a second detection module 22. The buffer station 21 is located downstream of the second conveying module 16 and is used to buffer the second carrier 20. The labeling module 26 is used to pick up the label 25 located on the second carrier 20 and transfer and attach the label 25 to the outer surface of the packaging box 24 located on the second carrier 20. The second detection module 22 is located downstream of the labeling module 26 and is used to detect the appearance of the package 24 after labeling.

[0093] A buffer platform 21 is located downstream of the second conveying module 16 and is used to buffer the second carrier 20. The second carrier 20 is used to receive the packaging box 24 that has undergone opening, label 25 extraction, and closing operations on the second conveying module 16. A labeling module 26 is located near the buffer platform 21 and is used to perform label picking, peeling, and labeling operations. The labeling module 26 is equipped with a picking mechanism (second label suction head) that can accurately pick up the label 25 from the fifth feeding position 202 of the second carrier 20, transfer it according to a preset position, and affix it to a designated area (such as the side or top) on the outer surface of the packaging box 24 in the fourth feeding position 201.

[0094] After labeling is completed, the second carrier 20 is transported to the station of the second inspection module 22 via the third conveyor module. The second inspection module 22, located downstream of the labeling module 26, is equipped with a high-resolution industrial camera and image processing system for comprehensive appearance inspection of the labeled packaging box 24. Inspection includes, but is not limited to: whether the label 25 is accurately positioned, whether the label 25 is flat, whether there is any damage or omission, whether the printed content is clear and complete, and whether the packaging box 24 has any scratches, deformation, dirt, gaps, or other appearance defects. Inspection results can be uploaded to the production management system in real time. Qualified products proceed to the next packaging or palletizing process, while unqualified products are automatically marked and rejected, thus achieving closed-loop control of product quality.

[0095] In other embodiments, the electronic cigarette automatic packaging line also includes a second weighing module and a second sampling inspection module downstream of the second detection module 22.

[0096] In one implementation, please refer to Figures 16 to 19 The automatic packaging line for electronic cigarettes also includes a label peeling module 23 and a waste box 27. The label peeling module 23 includes a label peeling platform 231 and label peeling claws 232. The label peeling platform 231 is used to carry the label 25 to be peeled off. The label 25 includes a body layer 251 and a release film layer 252 stacked on top of each other. The release film layer 252 protrudes from the edge of the label peeling platform 231. The label peeling claws 232 are used to hold the protruding part of the release film layer 252. The labeling module 26 includes a second label suction head for adsorbing the body layer 251. When the release film layer 252 is held and fixed by the label peeling claws 232, the second label suction head peels the body layer 251 off the release film layer 252 through relative movement. The waste box 27 is provided with a receiving port 271. The waste box 27 collects the peeled release film layer 252 through the receiving port 271.

[0097] The label peeling platform 231 is used to hold the labels 25 to be peeled. Its surface is flat, ensuring that the labels 25 are in a stable and flat standby state before peeling. The labels 25 being processed are common release structures, including a body layer 251 (i.e., a functional label 25, such as a QR code, barcode, or text label) stacked on top of each other and a release film layer 252 (i.e., silicone paper or release film) located below it. The labels 25 on the fifth feeding position 202 are fed to the label peeling platform 231 by the second label suction head (not shown in the figure), and the edge portion of the release film layer 252 protrudes from the edge of the label peeling platform 231, forming a pre-peeled end that is easy to clamp.

[0098] During operation, the label-peeling gripper 232 actuates, precisely gripping and fixing the portion of the release liner 252 protruding from the platform edge. Simultaneously, the second label-adsorbing head adsorbs the body layer 251 of the label 25 using negative pressure. Subsequently, the second label-adsorbing head moves along a predetermined direction under the drive of a robotic arm or linear module, while the label-peeling gripper 232 remains fixed, creating relative motion between the two. During this process, the body layer 251 is gradually peeled off from the release liner 252, completing the label peeling action. This peeling method is stable and reliable, adaptable to labels 25 of different materials, thicknesses, and adhesive strengths, effectively avoiding problems such as label tearing, residual adhesive, or incomplete peeling.

[0099] After peeling, the second label suction head carries the separated body layer 251 to the outer surface of the packaging box 24 on the fourth feeding position 201 of the second carrier 20, and accurately attaches it to the designated position. At the same time, the peeled release film layer 252 is still held by the label peeling claw 232 or sent into the waste area by the traction mechanism. The waste box 27 is provided with a receiving port 271, located downstream of the label peeling platform 231 or on the waste output path, for receiving and collecting the peeled release film layer 252. The waste box 27 can be removed and cleaned periodically to avoid waste accumulation affecting equipment operation or polluting the production environment, and improves the cleanliness and maintenance convenience of the whole machine. Through the coordinated cooperation of the label peeling platform 231, the label peeling claw 232, and the second label suction head, the automatic and accurate peeling of the label 25 is realized; the introduction of the waste box 27 improves the waste handling process and realizes efficient, clean, and reliable automatic labeling.
