Description

Technical Field

[0001] This invention relates to the field of electronic cigarette manufacturing and assembly technology, and in particular to a multi-degree-of-freedom adjustable pressing device for assembling irregularly shaped electronic cigarette components. Background Technology

[0002] In the industrial mass production of e-cigarette products, the pressing and assembly device, as a core process equipment for assembling irregularly shaped components, plays an indispensable role in the precise control of product assembly accuracy, structural sealing, and appearance yield. Its working principle is based on precision displacement and pressure control. By changing the vertical stroke and output pressure of the pressing end, and in conjunction with precise station alignment, it completes the tight-fitting assembly of various irregularly shaped e-cigarette components. This type of device is widely used in many production stages such as e-cigarette component processing and final assembly, and is an important piece of equipment to ensure the stable and efficient operation of e-cigarette production lines.

[0003] Currently, although some electronic cigarette component pressing and assembly equipment exists on the market, there are still significant technical bottlenecks in the application of adapting irregularly shaped components. Some products use a fixed-station, single-degree-of-freedom pressing structure, which makes it difficult to adjust the alignment of the asymmetric pressing surfaces of irregularly shaped components. Manual adjustment is inefficient and lacks precision, making it difficult to achieve high-precision point alignment. Others use rigid clamping limiting structures, which result in uneven clamping force on irregularly shaped components with irregular outer contours. This can easily scratch the appearance of the components and cannot effectively prevent workpiece displacement during the pressing process. Still other devices have independent pressing and position detection processes, lacking closed-loop feedback control capabilities. This leads to large fluctuations in pressing quality during mass production, making it impossible to guarantee the consistency and stability of irregularly shaped component assembly and affecting the continuous and efficient operation of the production line.

[0015] Compared with related technologies, the multi-degree-of-freedom adjustable pressing device for assembling irregularly shaped electronic cigarette components provided by the present invention has the following beneficial effects: 1. This invention provides a multi-degree-of-freedom adjustable pressing device for assembling irregularly shaped electronic cigarette components. The vertical displacement mechanism uses a cylinder-slide rail transmission structure to drive the pressing end to rise and fall vertically, outputting pressing force. The horizontal displacement mechanism uses a reciprocating screw transmission structure to precisely shift the pressing end in the horizontal plane. A laser positioner projects a light spot to calibrate the pressing point, and sensors collect pressing stroke and pressure data in real time, feeding this data back to the drive end to form a closed-loop control system. This solves the problems of traditional pressing devices having only one degree of freedom, relying on manual operation for positioning adjustment, insufficient precision, lack of real-time control over pressing pressure and stroke, difficulty in meeting the high-precision assembly requirements of asymmetrical pressing surfaces of irregularly shaped electronic cigarette components, and poor batch assembly quality consistency.

[0016] 2. This invention provides a multi-degree-of-freedom adjustable pressing device for assembling irregularly shaped electronic cigarette components. The connecting rod is driven to rise and fall vertically by a second cylinder. The linkage, movable ring, connecting arm, and three sets of clamping arms that are circumferentially hinged form a linkage transmission clamping structure, which forms a three-point radial limit for the irregularly shaped component. The elastic pad on the inner side of the clamping arm and the flexible buffer layer on the inner wall of the placement port achieve flexible protection of the entire contact surface. This solves the problems of unstable clamping and positioning caused by the irregular outer contour of the irregularly shaped electronic cigarette component, easy displacement and movement during the pressing process, and easy scratching of the component's appearance by rigid clamping and support, and easy damage to the bottom of the component caused by the pressing impact.

[0017] 3. This invention provides a multi-degree-of-freedom adjustable pressing device for assembling irregularly shaped electronic cigarette components. By setting a first buffer at the top of the vertical movement stroke and setting an elastic spring in the clamping transmission structure, a multi-level buffer protection system is constructed to reduce the rigid impact of the movement. At the same time, it is combined with a side-mounted lifting cylinder and a rotary drive motor to work with the clamping device to realize automatic loading and unloading and workpiece repositioning at the pressing station. This solves the problems of large rigid collision loss at the moving end of the pressing device, poor equipment smoothness and short service life, as well as low efficiency of manual loading and unloading, large deviation of workpiece placement position and insufficient adaptability to continuous production.

[0021] Please see Figures 1-10This invention provides a technical solution: a multi-degree-of-freedom adjustable pressing device for assembling irregularly shaped electronic cigarette components, comprising a worktable 1, an adjusting device 2, and a limiting device 3. The adjusting device 2 is mounted above the worktable 1 and is used to achieve multi-degree-of-freedom precise adjustment of the pressing station and perform pressing assembly actions. The adjusting device 2 includes a vertical displacement mechanism, a horizontal displacement mechanism, a pressing actuator, and a positioning detection component.

The positioning detection component is used to identify the position of the component to be assembled and provide feedback adjustment signals. The limiting device 3 is fixed on the worktable 1 and corresponds to the pressing end of the adjusting device 2 below, and is used to support and clamp the irregularly shaped electronic cigarette component to prevent the component from shifting during the pressing process. The vertical displacement mechanism includes a mounting frame 201, a slide rail 202, a movable seat 205, a sliding block 206, and a first cylinder 216; Mounting bracket 201 is vertically fixedly mounted on one side of the workbench 1. Slide rail 202 is laid vertically on the inner side wall of mounting bracket 201. Sliding block 206 is fixedly provided on the outer side wall of movable seat 205. Sliding block 206 slides with slide rail 202. First cylinder 216 is fixedly provided at the bottom end of mounting bracket 201. The piston rod of first cylinder 216 extends upward and is fixedly connected to the bottom of movable seat 205, which is used to drive movable seat 205 to move vertically up and down along slide rail 202. The horizontal displacement mechanism includes a support base 207, a first drive motor 208, a slide 209, a reciprocating lead screw 210, and a movable seat 211; The support base 207 is horizontally fixedly installed on the side wall of the movable base 205 and moves vertically up and down synchronously with the movable base 205. The slide groove 209 is opened horizontally inside the support base 207. The reciprocating screw 210 is rotatably mounted in the slide groove 209 and arranged along the extension direction of the slide groove 209. The first drive motor 208 is fixed to one end of the outer wall of the support base 207. Its output shaft extends into the slide groove 209 and is coaxially fixedly connected to the end of the reciprocating screw 210. The movable base 211 is slidably embedded in the slide groove 209 and threadedly connected to the reciprocating screw 210. A presser 212 is fixedly installed on the outer wall of the movable base 211 away from the movable base 205. It moves horizontally synchronously with the movable base 211 and is vertically pressed synchronously with the movable base 205. A first L-shaped support plate 203 is fixedly installed at the upper end of the mounting bracket 201. A first buffer 204 is fixedly installed on the side of the first L-shaped support plate 203 facing the movable seat 205. The first buffer 204 is used to limit the vertical lifting stroke of the movable seat 205 and buffer the end impact. Both ends of the support base 207 are fixedly provided with a second L-shaped support plate 217. A second buffer 218 is fixedly installed on the side of the second L-shaped support plate 217 facing the movable base 211. The second buffer 218 is used to limit the horizontal movement of the movable base 211 and buffer the end impact. The positioning and detection assembly includes a fixed base 213, a laser positioner 214, and a sensor 215; The fixed base 213 is fixedly installed on the side outer wall of the movable base 211. The laser positioner 214 and the sensor 215 are both fixedly installed on the fixed base 213. The emitting end of the laser positioner 214 is vertically facing the downward limiting device 3, which is used to project a positioning spot to calibrate the pressing point. The sensor 215 is used to detect the pressing stroke and pressing pressure in real time and output a detection feedback signal. The signal output terminal of sensor 215 is connected to the control terminal signals of the first cylinder 216 and the first drive motor 208 respectively, and is used to adjust the pressing stroke and horizontal position according to the detected pressing pressure and position signal feedback to realize closed-loop precise control of the pressing process. In this implementation scheme, before the pressing operation, a positioning spot is first projected downward by the laser positioner 214. The control system starts the first drive motor 208 to drive the reciprocating screw 210 to rotate according to the deviation between the spot and the position to be pressed of the electronic cigarette component 306 below. The screw drives the movable seat 211 to move horizontally along the slide groove 209 through the threaded transmission, which drives the presser 212 and the positioning detection component to adjust the horizontal position synchronously until the positioning spot and the point to be pressed are completely coincident, thus completing the horizontal alignment calibration. During the pressing process, the first cylinder 216 pushes the movable seat 205 to move downward along the slide rail 202, which drives the presser 212 to descend synchronously through the support seat 207, applying a pressing force to the irregular electronic cigarette component on the lower limiting device 3. Sensor 215 collects pressing stroke data and pressing pressure values ​​in real time and feeds the detection signals back to the control terminals of the first cylinder 216 and the first drive motor 208: when the pressing pressure reaches a preset threshold, the first cylinder 216 is controlled to stop pressing and enter a pressure holding state; when a horizontal position deviation is detected during the pressing process, the first drive motor 208 is synchronously controlled to perform horizontal position micro-compensation, realizing closed-loop precise control of the entire pressing process. When the moving seat 205 rises to the top of its stroke, its top contacts the first buffer 204, which absorbs the impact kinetic energy, limits the maximum vertical stroke, and avoids rigid collisions.

[0022] The limiting device 3 includes a fixed base plate 301, a supporting column 302, a supporting member 303, a fixed top plate 304, and a support 307; The fixed base plate 301 is fixedly installed inside the workbench 1, the support column 302 is vertically fixed to the top of the fixed base plate 301, the fixed top plate 304 is horizontally fixed to the top of the support column 302, the support member 303 is supported between the fixed base plate 301 and the fixed top plate 304 to strengthen the support strength, and the support 307 is fixedly installed between the fixed top plate 304 and the fixed base plate 301. The fixed top plate 304 has a through plate opening 305 in the center, and the support 307 has several seat grooves 308 in the circumferential direction inside. The seat grooves 308 are used to provide movement space for the clamping mechanism. The top of the support 307 has a through seat hole 309. The limiting device 3 also includes a clamping mechanism, which includes a connecting rod 310, a movable ring 312, a first connecting piece 313, an elastic spring 318, and a second cylinder 319. The connecting rod 310 is slidably disposed inside the support 307. The outer wall of the connecting rod 310 is slidably inserted into the inner wall of the seat hole 309. The top of the connecting rod 310 is provided with a placement opening 311 for placing the electronic cigarette component 306. The movable ring 312 is fixedly sleeved on the outer wall of the connecting rod 310. Three first connecting members 313 are provided. Each first connecting member 313 is fixedly connected to the outer wall of the movable ring 312. A connecting arm 314 is rotatably provided on the inner wall of each first connecting member 313. One end of each connecting arm 314 is hinged to the movable ring 312 through the corresponding first connecting member 313. The other end of each connecting arm 314 is hinged to the lower part of the clamping arm 315 through the corresponding fixed rod 316. Three second connecting members 317 are fixedly provided on the outer wall of the support 307. The second connecting members 317 correspond one-to-one with the clamping arms 315. The middle part of the clamping arm 315 is hinged to the corresponding second connecting member 317, forming a connecting rod clamping transmission structure. The second cylinder 319 is fixedly installed at the top center of the fixed base plate 301. The piston rod of the second cylinder 319 extends upward and is fixedly connected to the bottom end of the connecting rod 310, which is used to drive the connecting rod 310 to make vertical lifting and lowering movements along the seat hole 309. The elastic spring 318 is connected between the bottom of the inner wall of the support 307 and the outer wall of the bottom of the movable ring 312, and is used to provide elastic buffering and reset assistance for the lifting and lowering movement of the movable ring 312. Each clamping arm 315 has an elastic pad 320 fixedly installed on the inner wall of its clamping end. The elastic pad 320 is in flexible contact with the outer wall of the electronic cigarette component 306 to avoid scratching the surface of the component during clamping. The inner wall of the placement port 311 is provided with a flexible buffer layer to buffer the impact force of pressing when supporting the component. In this embodiment, when the electronic cigarette component 306 is placed, the piston rod of the second cylinder 319 is in the extended state, pushing the connecting rod 310 to slide upward along the seat hole 309, causing the movable ring 312 to rise synchronously; at this time, the connecting arm 314 moves upward with the movable ring 312, pulling the lower end of the clamping arm 315 outward, and the clamping arm 315 rotates around the hinge point between the middle part and the second connecting member 317 as the fulcrum, so that the upper clamping end opens outward, completely exposing the placement opening 311 at the top of the connecting rod 310; After the irregularly shaped electronic cigarette component is placed in the placement port 311, the piston rod of the second cylinder 319 retracts, pulling the connecting rod 310 and the movable ring 312 downward. The connecting arm 314 pushes the lower end of the clamping arm 315 inward, causing the clamping end of the upper end of the clamping arm 315 to move closer to the outer wall of the component. Finally, the three clamping arms 315, which are evenly arranged in the circumference, form a three-point clamping limit for the electronic cigarette component 306. This can adapt to irregularly shaped components with different outer contours and ensure that the component does not shift or move horizontally during the pressing process. The elastic spring 318 is compressed during the descent of the movable ring 312, providing a reverse elastic support force to buffer the driving impact of the second cylinder 319, while providing a reset assist when the piston rod extends, thus improving the smoothness of the clamping action. The elastic pad 320 on the inner side of the clamping arm 315 is flexibly attached to the outer wall of the component, which can increase the clamping friction and improve the reliability of the limit, and also prevent rigid clamping from scratching the appearance of the irregularly shaped component. The flexible buffer layer on the inner wall of the placement port 311 can absorb the vertical impact force during the pressing process, form protection for the bottom of the component, and avoid stress concentration during pressing that could cause damage to the bottom of the component.

[0023] It also includes a base 4, a third cylinder 5, and a second drive motor 6. The third cylinder 5 is fixedly installed on the top of the base 4, and the second drive motor 6 is fixedly connected to the top of the piston rod of the third cylinder 5. The output end of the second drive motor 6 is provided with a clamping device 7 for replacing the electronic cigarette component 306. In this embodiment, the base 4 is arranged to the side of the workbench 1. The third cylinder 5 can drive the second drive motor 6 and the clamping device 7 to move vertically up and down as a whole. The second drive motor 6 can drive the clamping device 7 to rotate back and forth in the horizontal plane. After a single pressing operation is completed and the clamping arm 315 releases the part, the third cylinder 5 raises the clamping device 7 to the same height as the limiting device 3. The second drive motor 6 drives the clamping device 7 to rotate directly above the pressing station. After the clamping device 7 grabs the assembled part, the second drive motor 6 rotates to the unloading position to release the part. Then the clamping device rotates to the loading position to grab the electronic cigarette part to be assembled. After rotating back to the pressing station, it accurately places the part in the placement port 311, completing the automatic loading and unloading replacement. There is no need for manual picking and placing of parts, which improves the automation level and production efficiency of the assembly operation, while avoiding the positional deviation caused by manual placement, ensuring the consistency and accuracy of pressing alignment.

[0024] Working principle: In the initial state, the piston rod of the second cylinder 319 is in the extended state, pushing the connecting rod 310 to slide upward along the seat hole 309 of the support 307, and simultaneously driving the movable ring 312 to rise; the movable ring 312 pulls the upper end of the connecting arm 314 upward through the three circumferentially arranged first connecting parts 313, causing the connecting arm 314 to open outward, thereby driving the lower end of the clamping arm 315 to extend outward; the clamping arm 315 rotates around the hinge point between the middle part and the second connecting part 317 as the fulcrum, and the upper clamping end opens outward simultaneously, completely exposing the placement opening 311 at the top of the connecting rod 310; After the irregularly shaped electronic cigarette component to be assembled is placed into the placement port 311, the piston rod of the second cylinder 319 retracts, pulling the connecting rod 310 and the movable ring 312 downwards in sync; the connecting arm 314 moves downwards with the movable ring 312, pushing the lower end of the clamping arm 315 to retract inwards, and causing the upper end of the clamping arm 315 to move closer to the outer wall of the component. Finally, the electronic cigarette component 306 is clamped in a three-point ring-like manner by the three clamping arms 315 evenly distributed in the circumference, completing the radial limit of the workpiece and preventing the component from horizontally shifting or rotating during the pressing process; During clamping, the elastic spring 318 is compressed as the movable ring 312 moves downward, providing a reverse elastic buffer force to counteract the rigid impact of the second cylinder 319, making the clamping action transition smoothly; the elastic pad 320 on the inner side of the clamping arm 315 flexibly fits against the outer wall of the component, which increases the clamping friction and improves the reliability of the limit, while avoiding rigid clamping damage to the surface of the component; the flexible buffer layer on the inner wall of the placement port 311 supports the bottom of the component and can absorb the vertical impact force during the subsequent pressing process, avoiding stress concentration that could cause component damage; After the workpiece is clamped, the positioning and detection component is activated. The laser positioner 214 projects a positioning spot downwards, aligning it with the pressing point of the electronic cigarette component 306. The control system outputs an adjustment signal to the first drive motor 208 based on the horizontal deviation between the spot and the target point. The first drive motor 208 drives the reciprocating screw 210 to rotate, which drives the movable seat 211 to move horizontally along the slide groove 209 through the threaded transmission. Simultaneously, it drives the presser 212 and the positioning and detection component to move horizontally as a whole until the positioning spot and the pressing point are completely coincident, thus completing the precise horizontal alignment. After horizontal alignment is completed, the first cylinder 216 is activated, and the piston rod drives the moving seat 205 to move vertically up and down along the slide rail 202. Through the support seat 207, the presser 212 is driven to adjust the vertical height synchronously, control the vertical distance between the pressing end and the workpiece, complete the adjustment of the vertical station, and realize the multi-degree-of-freedom precise adjustment of the pressing station. When the movable seat 205 moves vertically to the upper end of its stroke, its top contacts the first buffer 204. The first buffer 204 absorbs the inertia of the motion, limits the maximum vertical stroke, and avoids a rigid collision between the movable seat 205 and the mounting bracket 201. After the workstation adjustment is completed, the first cylinder 216 drives the moving seat 205 to descend smoothly, and the presser 212 presses down and contacts the workpiece to be assembled, continuously outputting pressing force to complete the pressing assembly of the parts. During the pressing process, sensor 215 collects pressing stroke data and pressing pressure values ​​in real time, and feeds back the detection signals to the control terminals of the first cylinder 216 and the first drive motor 208 in real time: when the pressing pressure reaches the preset assembly threshold, the first cylinder 216 is controlled to stop pressing and enter the pressure holding state to ensure the consistency of pressing depth and assembly tightness; when the horizontal position offset is detected to exceed the allowable range during the pressing process, the first drive motor 208 is controlled to start and stop to perform horizontal position micro-compensation, and the pressing point is corrected in real time to achieve closed-loop precise control of the entire pressing process, which can adapt to the assembly requirements of asymmetric pressing surfaces of irregular parts; After the pressing and holding time reaches the set value, the first cylinder 216 drives the moving seat 205 and the presser 212 to move upward and reset; the piston rod of the second cylinder 319 extends, pushing the connecting rod 310 upward, and the clamping arm 315 opens simultaneously to release the clamping of the workpiece. At this time, the side auxiliary loading and unloading mechanism is activated: the third cylinder 5 lifts the second drive motor 6 and the clamping device 7 to the same height as the workpiece. The second drive motor 6 drives the clamping device 7 to rotate to the top of the pressing station. After the clamping device 7 grabs the assembled workpiece, the second drive motor 6 rotates to the unloading position to release the workpiece. Then the clamping device 7 rotates to the loading position to grab the workpiece to be assembled, and rotates back to the pressing station to put the workpiece into the placement port 311, completing a single operation cycle. By repeating this process, continuous pressing and assembly of irregularly shaped electronic cigarette parts can be achieved.
