Description

Technical Field

[0001] This invention relates to the field of lighter manufacturing equipment technology, and in particular to a vision-based lighter material feeding device and its usage method. Background Technology

[0002] As a small fire-starting device, the production and assembly of lighters involves multiple processes. After assembly, the lighters need to be arranged in a specific pattern and placed into packaging boxes or trays for storage and transport. This process is usually called the stacking process.

[0003] In the existing lighter stacking operation, the lighters conveyed on the conveyor belt are picked up one by one and placed into the storage box manually. This manual stacking method is inefficient and is prone to uneven arrangement or omission of lighters due to human factors. Some material stacking equipment uses a rigid pushing mechanism to push lighters into the placement box. However, since the lighter shells are mostly thin-walled plastic parts with low mechanical strength, if jamming occurs during the rigid pushing process, the push plate can easily crush the lighter shell, causing internal flammable gas to leak, which poses a safety hazard. In addition, during the conveying and pushing process, lighters are prone to generating static charge due to friction with components such as conveyor belts and push plates. When the static charge accumulates to a certain level and is released instantaneously, it may generate an electric spark. Since there are usually trace amounts of flammable gas escaping at the lighter stacking station, the electric spark may cause a combustion or explosion accident. Before lighters enter the material processing stage, it is usually necessary to inspect and reject any defects in their appearance. Some existing inspection equipment uses industrial cameras in conjunction with image recognition technology to inspect the appearance of lighters. However, the protective glass of industrial cameras is prone to dust accumulation during long-term use, which affects the clarity of the images and leads to the failure to detect defective products.

[0004] Therefore, it is necessary to provide a material feeding device that can automatically perform visual inspection of lighters, defect removal, and material feeding, and has explosion-proof protection and static electricity elimination during the feeding process. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing lighter material feeding processes, such as the inability to remove defective products online, the easy crushing of thin-walled shells during material feeding, and the easy ignition of flammable gases by frictional static electricity. The invention proposes a vision-based lighter material feeding device and its usage method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A vision-based lighter material feeding device includes a workbench.

A placement box is slidably connected to the top of the workbench, and the placement box is used to place the lighter body. One end of the placement box passes through the conveyor belt and extends into the placement platform. An electric push rod IV is fixed inside the placement platform. One end of the piston rod of the electric push rod IV abuts against one side of the placement box, and is used to push the placement box away from the placement platform. The C-shaped frame II is provided with a flipping mechanism, which is used to flip the lighter body pushed by the push plate II and insert the lighter body vertically into the placement box. The flipping mechanism includes a rotating shaft that passes through the C-shaped frame II and a flipping plate fixed to the outer wall of the rotating shaft. The top of the flipping plate is flush with the top of the conveyor belt. The flipping plate corresponds to the position of the push plate II. The placement box is located below the flipping plate.

[0007] In one possible design, the screening mechanism further includes an industrial camera fixed to the inner top wall of the C-frame I. One end of the piston rod of the electric push rod I extends into the C-frame I. The push plate I is disposed within the C-frame I for discharging the lighter body conveyed on the conveyor belt. A discharge port is provided on the side of the C-frame I away from the electric push rod I. Inclined surfaces are provided on both sides of the discharge port to guide the lighter body into the discharge port. A receiving plate is fixed to the inner wall of the side of the C-frame I away from the electric push rod I, and the top of the receiving plate is flush with the top of the conveyor belt. A guide ramp is fixed to the side of the C-frame I away from the electric push rod I, and the guide ramp is located below the discharge port. A protective box is fixed to the inner top wall of the C-frame I, and the industrial camera is disposed within the protective box. A protective glass is fixedly embedded in the bottom of the protective box, and a cleaning mechanism is provided at the bottom of the protective box for cleaning the protective glass.

[0008] In one possible design, the cleaning mechanism includes a rotating shaft rotating at the bottom of the protective box. A rotating arm is fixedly sleeved on the outer wall of the rotating shaft. A rubber wiper is fixed to the top of the rotating arm for cleaning the bottom of the protective glass. A torsion spring is fixed between the top of the rotating arm and the bottom of the protective box via a spring seat, and the torsion spring is sleeved on the outer wall of the rotating shaft for driving the rotating arm to rotate and then return to its original position. A rotating disk is fixed to the bottom end of the rotating shaft. A cable is wound around the outer wall of the rotating disk. A guide wheel is rotatably connected to the inner wall of the C-shaped frame I near the electric push rod I via a base plate, and the guide wheel is used for... The cable is guided by two bases fixed on the inner wall of the C-frame I near the electric push rod I. The bases are located below the guide wheel and above the push plate I. A rotating plate is rotatably connected between the two bases. The bottom end of the cable is fixedly connected to the top of the rotating plate near the electric push rod I. An arc-shaped block is fixed to the bottom of the rotating plate away from the electric push rod I. The arc-shaped block cooperates with the push plate I to drive the rotating plate to rotate clockwise when the push plate I moves. A limiting plate is fixed between the two bases at the top of the rotating plate. The limiting plate is located on the top of the rotating plate away from the arc-shaped block.

[0009] In one possible design, the clearance protection mechanism further includes multiple fixing rods, which are fixed to the side of the push plate II near the electric push rod II. The other end of each fixing rod is fixedly connected to a magnetic ring I, which is located on the side of the magnetic ring II near the electric push rod II. Magnetic attraction is generated between the magnetic ring I and the magnetic ring II.

[0010] In one possible design, the top of the workbench is fixed with multiple L-shaped support rods, which are divided into horizontal and vertical sections. One end of the horizontal end of the multiple L-shaped support rods extends above the conveyor belt and is fixed with a baffle I. One end of the push plate II slides in cooperation with the side of the baffle I near the conveyor belt.

[0011] In one possible design, the flipping mechanism further includes a drive motor fixed to one side of the C-frame II. The output shaft of the drive motor is fixedly connected to one end of a rotating shaft via a coupling. Multiple electric push rods III are fixed to the top of the C-frame II. The cylinders of the multiple electric push rods III are all fixed to the top of the C-frame II. The bottom ends of the piston rods of the multiple electric push rods III extend into the C-frame II and are fixed with a push plate. A baffle II is fixed to the bottom of the push plate on the side away from the flipping plate, which is used to limit the lighter body when the flipping plate is flipped 90° to make the lighter body vertical. A rubber strip is fixed to the bottom of the push plate, which is used to push the vertically placed lighter body down and lock it into the placement box.

[0012] In one possible design, the top of the flip plate has two baffles fixed to limit the movement of multiple lighter bodies, and the push plate has two clearance openings on the side near the flip plate to allow the baffles to move when the flip plate is rotated to a vertical position.

[0013] In one possible design, a control center is fixed on the top of the worktable, and the control center is electrically connected to electric actuators IV, III, and II, a drive motor, electric actuator I, and an industrial camera.

[0014] In one possible design, a conductive copper plate is fixedly embedded in the top of the flip plate, and carbon fiber brush filaments are fixed in the top of the conductive copper plate. A conductive grounding wire is connected inside the rotating shaft through a conductive slip ring. One end of the conductive grounding wire extends into the flip plate and is fixedly connected to the conductive copper plate, and the other end of the conductive grounding wire extends to one side of the rotating shaft and is grounded.

[0015] A method for using a vision-based lighter material feeding device includes the following steps: S1. The conveyor belt transports the lighter body to the stacking station. When it passes through the screening station in C-frame I, the industrial camera takes an image and transmits it to the control center. The control center judges the appearance defects. When it is determined to be a defective product, it controls the electric push rod I to drive the push plate I to push the defective product away from the conveyor belt and fall into the waste collection box through the discharge port and the guide inclined plate. S2. When the electric push rod I drives the push plate I to remove defective products, the push plate I abuts against the arc block to make the rotating plate rotate. The rotating plate drives the rotating shaft and rotating arm to rotate via the cable and rotating disk. The rubber wiper wipes the protective glass. After the push plate I is reset, the torsion spring makes the rubber wiper reset. S3. The qualified lighter bodies are arranged in a row by the limit of the baffle I. When they reach the predetermined position, the electric push rod II extends and the magnetic attraction of the magnet ring II and the magnet ring I drives the push plate II to push the lighter body horizontally onto the flip plate. S4. When the lighter body is stuck, the pushing resistance exceeds the magnetic attraction between magnet ring I and magnet ring II, magnet ring I separates from magnet ring II, the piston rod of electric push rod II moves during its free stroke, and push plate II stops moving forward. S5. After the lighter body reaches the flip plate, the drive motor drives the flip plate to rotate via the rotating shaft, flipping the lighter body into a vertical state. The stop bar limits the deviation. After flipping, the electric push rod III pushes the lower push plate down, and the rubber strip pushes the vertical lighter body into the placement slot of the placement box. S6. The static charge generated by the friction between the lighter body and the flip plate is conducted to the grounding wire through the carbon fiber brush and the conductive copper plate. After the push plate is pushed in, the electric push rod IV pushes the placement box to move one placement slot spacing so that the next empty slot is aligned with the flip plate.

[0016] Beneficial effects: In this invention, by setting a screening mechanism consisting of an industrial camera and an electric push rod I inside the C-frame I, online visual inspection of the lighter bodies on the conveyor belt and automatic rejection of defective products can be performed. After the images captured by the industrial camera are analyzed and processed by the control center, the surface defects of the lighter bodies can be accurately identified. The electric push rod I drives the push plate I to push the defective products out of the conveyor belt, thereby realizing the automatic rejection of defective products and improving the consistency of product quality. In this invention, a cleaning mechanism is set at the bottom of the protective box. The power of the push plate I when moving to remove defective products drives the rotating arm and rubber wiper to wipe and clean the protective glass. No additional drive source is required. The device itself is used, which simplifies the structure and reduces maintenance costs. At the same time, regular cleaning of the protective glass can maintain the clarity of the industrial camera and avoid misjudgment and missed detection caused by dust. In this invention, a clearance protection mechanism consisting of a magnetic ring I, a magnetic ring II, and a fixed rod is set between the push plate II and the electric push rod II. Magnetic attraction is used as the power transmission medium to achieve real-time response to pushing resistance. When the lighter body gets stuck during the pushing process, the magnetic ring I and magnetic ring II automatically disengage, and the push plate II stops moving, thus preventing the lighter body from being crushed. In this invention, by setting a flipping mechanism consisting of a drive motor, a rotating shaft and a flipping plate, the lighter body pushed by the pusher plate II can be flipped from a horizontal state to a vertical state and inserted into the placement box in a vertical posture. The flipping and stacking method can make the lighter body fit into the placement box in a compact arrangement, which improves the stacking density and packaging efficiency. In this invention, by setting a conductive copper plate, carbon fiber brush filaments, and a conductive grounding wire on the flip plate, and setting a conductive grounding wire inside the rotating shaft, a static discharge path is formed from the lighter body to the ground. The static charge generated by the friction between the lighter body and the flip plate and the carbon fiber brush filaments can be continuously and steadily introduced to the ground through this path, avoiding the accumulation of static charge and instantaneous discharge. This static elimination method can prevent electric sparks from being generated at the material stacking station where flammable gases are present, thus improving the safety performance of the device.

[0017] In this invention, an industrial camera and an electric push rod I are used to visually inspect and remove defects from the lighter body. The cleaning mechanism uses the power of removing defective products to clean the protective glass. The protective mechanism transmits power through the magnetic attraction of magnetic rings I and II, automatically making way when the lighter is jammed to prevent it from being crushed. The flipping mechanism flips the lighter body and inserts it vertically into the placement box. The carbon fiber brush, together with the conductive grounding wire, conducts the static charge generated by friction to the ground, eliminating static sparks. This device integrates visual inspection, defect removal, explosion-proof pushing, flipping and stacking, and static elimination, enabling automation and safety in the lighter stacking operation.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In one embodiment: Refer to Figure 1 and Figure 2 A vision-based lighter material feeding device, relating to the field of lighter production equipment technology, includes a workbench 1. A conveyor belt 2 is mounted on the top of the workbench 1 via a mounting frame. The conveyor belt 2 is used to transport lighter bodies 46. The conveyor belt 2 can be a belt conveyor, consisting of a drive roller, a driven roller, and a conveyor belt wrapped around the roller. The drive roller is driven to rotate by a motor, thereby driving the conveyor belt. The conveying direction of the conveyor belt 2 can be set according to the production line layout. In this embodiment, the conveyor belt 2 transports the lighter bodies 46 in a horizontal direction.

[0022] Reference Figure 1 and Figure 2 A C-shaped frame I3 is fixed to the top of the workbench 1. The opening of the C-shaped frame I3 faces downward. A screening mechanism is installed inside the C-shaped frame I3. The screening mechanism is used to discharge defective lighter bodies 46 from the conveyor belt 2. The screening mechanism includes an electric push rod I4 fixed to one side of the C-shaped frame I3 and a push plate I5 fixed to one end of the piston rod of the electric push rod I4. The C-shaped frame I3 provides a guiding space for the movement of the push plate I5. The cylinder of the electric push rod I4 is fixed to the outer wall of the C-shaped frame I3. The piston rod of the electric push rod I4 extends horizontally into the interior of the C-shaped frame I3. The push plate I5 is fixed to the end of the piston rod. The pushing direction of the push plate I5 is perpendicular to the conveying direction of the conveyor belt 2.

[0023] Reference Figures 1-3 The screening mechanism also includes an industrial camera 6 fixed to the inner top wall of the C-frame I3. The industrial camera 6 is used to capture images of the lighter body 46 conveyed on the conveyor belt 2. The industrial camera 6 can be a CCD industrial camera or a CMOS industrial camera. A mounting hole is provided on the inner top wall of the C-frame I3. The lens of the industrial camera 6 passes through the mounting hole and faces the conveyor belt 2. A protective box 10 is fixed to the inner top wall of the C-frame I3. The industrial camera 6 is placed inside the protective box 10. The protective box 10 is used to protect the industrial camera 6 and prevent dust, debris, etc. from entering the interior of the industrial camera 6. A protective glass 11 is fixedly embedded at the bottom of the protective box 10. The protective glass 11 is located directly below the lens of the industrial camera 6. The transparent area of ​​the protective glass 11 matches the field of view of the industrial camera 6, so that the industrial camera 6 can capture images of the lighter body 46 on the conveyor belt 2 through the protective glass 11.

[0024] Reference Figure 2 , Figure 3 and Figure 6 One end of the piston rod of the electric push rod I4 extends into the C-frame I3. A push plate I5 is located within the C-frame I3. The push plate I5, driven by the electric push rod I4, pushes out the defective lighter body 46 conveyed on the conveyor belt 2. A discharge port 7 is located on the side of the C-frame I3 away from the electric push rod I4. The discharge port 7 penetrates the side wall of the C-frame I3. Both sides of the discharge port 7, away from each other, have inclined surfaces. These inclined surfaces guide the lighter body 46 into the discharge port 7. The width and height of the discharge port 7 are both larger than the external dimensions of the lighter body 46 to ensure that the lighter body 46 can pass through smoothly. The C-frame I3 is located away from the electric push rod I4. A receiving plate 8 is fixed to one inner wall. The top of the receiving plate 8 is flush with the top of the conveyor belt 2. The receiving plate 8 is used to receive the lighter body 46 pushed by the pusher plate I5. One end of the receiving plate 8 is connected to the side of the conveyor belt 2, and the other end extends to the edge of the discharge port 7. A guide plate 9 is fixed to the side of the C-shaped frame I3 away from the electric push rod I4. The guide plate 9 is located below the discharge port 7. The guide plate 9 is inclined. Its higher end is fixedly connected to the outer wall of the C-shaped frame I3, and its lower end is inclined downward and extends to the top of the waste collection box. The guide plate 9 is used to guide the lighter body 46 discharged through the discharge port 7 into the waste collection box.

[0025] Specifically, as the conveyor belt 2 transports the lighter body 46 to one side, the industrial camera 6 captures an image of the lighter body 46. The image captured by the industrial camera 6 is transmitted to the control center 47. The control center 47 has a built-in image processing module that analyzes the captured image to determine whether the lighter body 46 has any cosmetic defects. When the control center 47 determines that the lighter body 46 has defects, the control center 47 controls the electric push rod I4 to move. The piston rod of the electric push rod I4 extends and pushes the push plate I5 towards the discharge port 7. The push plate I5 pushes the lighter body 46 on the conveyor belt 2 towards the discharge port 7. The lighter body 46 is first pushed onto the receiving plate 8, then passes through the receiving plate 8 through the discharge port 7, and falls onto the guide inclined plate 9. The guide inclined plate 9 guides the lighter body 46 into the waste collection box, completing the automatic rejection of defective products.

[0026] Reference Figures 2-5The bottom of the protective box 10 is equipped with a cleaning mechanism for cleaning the protective glass 11 to prevent dust from affecting the clarity of the industrial camera 6. The cleaning mechanism includes a rotating shaft 12 rotatably connected to the bottom of the protective box 10. The rotating shaft 12 is vertically arranged, and a rotating arm 13 is fixedly sleeved on the outer wall of the rotating shaft 12. One end of the rotating arm 13 is fixedly connected to the rotating shaft 12, and the other end extends away from the rotating shaft 12. A rubber wiper 14 is fixed to the top of the rotating arm 13. The top of the rubber wiper 14 abuts against the bottom of the protective glass 11. The rubber wiper 14 is used for cleaning the protective glass 11. Dust at the bottom of the protective glass 11 is scraped off as the rotating arm 13 rotates. A torsion spring 15 is fixed between the top of the rotating arm 13 and the bottom of the protective box 10 via a spring seat. The torsion spring 15 is sleeved on the outer wall of the rotating shaft 12. One end of the torsion spring 15 is fixedly connected to the bottom of the protective box 10, and the other end is fixedly connected to the top of the rotating arm 13. The torsion spring 15 is used to provide a reset driving force after the rotating arm 13 rotates. A rotating disk 16 is fixed to the bottom end of the rotating shaft 12. A cable 17 is wound around the outer wall of the rotating disk 16. One end of the cable 17 is fixedly connected to the outer wall of the rotating disk 16, and the other end extends downward. The C-shaped frame I3 leans against... A guide wheel 18 is rotatably connected to the inner wall of the side near the electric push rod I4 via a base plate. The guide wheel 18 guides the cable 17. The guide wheel 18 is located below the rotating disk 16. The cable 17 extends downward after passing over the guide wheel 18. Two bases 19 are fixed to the inner wall of the C-shaped frame I3 near the electric push rod I4. The bases 19 are located below the guide wheel 18 and are spaced apart horizontally. A rotating plate 20 is rotatably connected between the two bases 19. The middle part of the rotating plate 20 is rotatably connected to the two bases 19 via a pin. The bottom end of the cable 17 is flush with the top of the rotating plate 20 near the electric push rod I4. The rotating plate 20 is fixedly connected to the electric push rod I4. An arc-shaped block 21 is fixed to the bottom of the rotating plate 20 on the side away from the electric push rod I4. The arc-shaped block 21 protrudes in the direction away from the electric push rod I4 and cooperates with the push plate I5. The arc-shaped block 21 is used to abut against the push plate I5 when the push plate I5 moves in the direction away from the electric push rod I4, thereby driving the rotating plate 20 to rotate clockwise. A limit plate 22 is fixed between the two bases 19. The limit plate 22 is set on the top of the rotating plate 20. The limit plate 22 is located on the top of the rotating plate 20 on the side away from the arc-shaped block 21. The limit plate 22 is used to limit the counterclockwise rotation angle of the rotating plate 20.

[0027] Specifically, during the defective product rejection process, when the electric push rod I4 pushes the push plate I5 towards the discharge port 7, the push plate I5 abuts against the arc-shaped block 21. Since the arc-shaped block 21 is fixed to the bottom of the rotating plate 20 on the side away from the electric push rod I4, the push plate I5 generates an upward thrust on the arc-shaped block 21. This thrust drives the rotating plate 20 to rotate clockwise around its rotational connection point with the base 19. When the rotating plate 20 rotates clockwise, the end of the rotating plate 20 near the arc-shaped block 21 rotates upward, and the end of the rotating plate 20 near the cable 17 rotates downward. When the end of the rotating plate 20 near the cable 17 rotates downward, it generates a downward pulling force on the cable 17. After being guided by the guide wheel 18, the portion of the cable 17 located between the rotating disk 16 and the guide wheel 18 is subjected to a downward pulling force. This pulling force drives the rotating disk 16 to rotate clockwise, and the rotating disk 16 drives the rotating plate to rotate clockwise. The rotating shaft 12 rotates synchronously, driving the rotating arm 13 to rotate. When the rotating arm 13 rotates, the rubber wiper 14 on its top scrapes across the bottom of the protective glass 11, removing dust from the bottom of the protective glass 11. When the push plate I5 is reset under the drive of the electric push rod I4, the push plate I5 disengages from the arc block 21. Under the elastic reset force of the torsion spring 15, the rotating arm 13 rotates in the opposite direction around the rotating shaft 12, returning to the initial position. The rotating arm 13 drives the rotating disk 16 to rotate in the opposite direction through the rotating shaft 12. The rotating disk 16 coils the cable 17, restoring the cable 17 to a slack state. After the cable 17 is slack, the rotating plate 20 rotates in the opposite direction to reset under its own weight and the indirect action of the torsion spring 15. The limiting plate 22 limits the reverse rotation angle of the rotating plate 20, keeping the rotating plate 20 in the initial position, waiting for the next action.

[0028] Reference Figure 1 and Figure 7 A placement platform 23 is fixed to the top of the workbench 1. The top of the placement platform 23 is flush with the top of the conveyor belt 2. The placement platform 23 is located on one side of the conveyor belt 2, and its top plane is at the same level as the conveying surface of the conveyor belt 2. An electric push rod II 24 is fixed to the top of the placement platform 23. The cylinder of the electric push rod II 24 is fixed to the top of the placement platform 23. The piston rod of the electric push rod II 24 is horizontally set, and its extension and retraction direction is perpendicular to the conveying direction of the conveyor belt 2. A push plate II 25 is provided at one end of the piston rod of the electric push rod II 24. The push plate II 25 is equipped with... The push plate II 25 is placed on top of the conveyor belt 2. A gap is left between the lower surface of the push plate II 25 and the upper surface of the conveyor belt 2. This gap is smaller than the height of the lighter body 46 so that the push plate II 25 can push the lighter body 46 to move. The push plate II 25 is used to push the lighter body 46 conveyed on the conveyor belt 2 to one side so that the lighter body 46 enters the subsequent flipping station. A flexible pad, such as a silicone pad or a rubber pad, is provided on the side of the push plate II 25 near the lighter body 46 to reduce the impact force when the push plate II 25 contacts the lighter body 46.

[0029] Reference Figure 1 and Figure 7 Multiple L-shaped support rods 29 are fixed to the top of the workbench 1. The L-shaped support rods 29 are divided into horizontal and vertical sections. The bottom end of the vertical section of the L-shaped support rod 29 is fixedly connected to the top of the workbench 1. The horizontal section extends upward to the conveyor belt 2. One end of the horizontal end of the multiple L-shaped support rods 29 extends to the top of the conveyor belt 2 and is fixed with a baffle I 30. There is a gap between the lower surface of the baffle I 30 and the upper surface of the conveyor belt 2. This gap is smaller than the height of the lighter body 46. One end of the push plate II 25 slides and engages with the side of the baffle I 30 near the conveyor belt 2. The baffle I 30 is used to limit the lighter body 46 on the conveyor belt 2 so that the lighter body 46 is arranged side by side along the conveying direction on the conveyor belt 2. A photoelectric sensor (not shown in the figure) is fixed to the end of the baffle I 30 near the flip plate 33. The detection end of the photoelectric sensor faces the conveyor belt 2 and is used to detect whether the lighter body 46 has reached the predetermined push position. The photoelectric sensor is electrically connected to the control center 47.

[0030] Reference Figure 7 and Figure 8A clearance protection mechanism is provided between the push plate II 25 and the electric push rod II 24. This mechanism prevents the push plate II 25 from crushing the lighter body 46 due to jamming when pushing it. The protection mechanism includes a magnetic ring II 27 fixed to the outer wall of the piston rod of the electric push rod II 24 and a magnetic ring I 26 slidably sleeved on the outer wall of the piston rod of the electric push rod II 24. The inner wall of the magnetic ring I 26 has multiple guide ridges or keyways along the axial direction. The electric push rod II 25... The piston rod of 24 has a guide groove on its outer wall that mates with a guide protrusion or keyway to guide the magnetic ring I 26 to slide smoothly along the piston rod axial direction. Both magnetic ring I 26 and magnetic ring II 27 are annular and are fitted onto the outside of the piston rod of the electric push rod II 24. Magnetic ring I 26 is positioned on the side of magnetic ring II 27 closest to the cylinder body of the electric push rod II 24. The inner diameter of magnetic ring I 26 is larger than the outer diameter of the piston rod of the electric push rod II 24, allowing magnetic ring I 26 to slide freely along the piston rod axial direction. (Protective mechanism) It also includes multiple fixing rods 28, which are fixed to the side of the push plate II 25 near the electric push rod II 24. The fixing rods 28 are distributed circumferentially around the push plate II 25. The other end of each fixing rod 28 is fixedly connected to a magnetic ring I 26. A magnetic attraction force is generated between the magnetic ring I 26 and the magnetic ring II 27. The magnetic poles of the opposite end faces of the magnetic ring I 26 and the magnetic ring II 27 are opposite, that is, the end of the magnetic ring I 26 facing the magnetic ring II 27 is the N pole, and the end of the magnetic ring II 27 facing the magnetic ring I 26 is the N pole. One end of 26 is the S pole, or vice versa. The magnetic attraction between magnet ring I 26 and magnet ring II 27 is set according to the rated thrust of electric push rod II 24 and the compressive strength of lighter body 46. When the resistance encountered by push plate II 25 when pushing lighter body 46 is less than the magnetic attraction, magnet ring I 26 and magnet ring II 27 remain attracted to each other; when the resistance encountered by push plate II 25 when pushing lighter body 46 is greater than the magnetic attraction, magnet ring I 26 and magnet ring II 27 disengage from each other.

[0031] Specifically, under normal operating conditions, when the piston rod of the electric push rod II 24 extends, the magnetic ring II 27 moves with the piston rod towards the push plate II 25. Due to the magnetic attraction between the magnetic ring I 26 and the magnetic ring II 27, the magnetic ring II 27 drives the magnetic ring I 26 to move synchronously through the magnetic attraction. The magnetic ring I 26 drives the push plate II 25 to move synchronously through the fixed rod 28. The push plate II 25 pushes the lighter bodies 46 arranged in a row on the conveyor belt 2 towards the flip plate 33. When the lighter body 46 is stuck, causing the resistance on the push plate II 25 to be greater than the magnetic attraction between the magnetic ring I 26 and the magnetic ring II 27, the magnetic ring I 26 and the magnetic ring II 27 move towards the push plate II 25. 7. Separation: Magnetic ring II 27 continues to move forward with the piston rod of electric push rod II 24, while magnetic ring I 26, fixed rod 28, and push plate II 25 stop moving. At this time, the idle stroke of the piston rod of electric push rod II 24 will not generate thrust on push plate II 25, and push plate II 25 will not further squeeze the stuck lighter body 46, thus preventing the lighter body 46 from being crushed. Afterwards, the staff can go forward to inspect and eliminate the jamming fault. After the jamming fault is eliminated, the piston rod of electric push rod II 24 retracts, and magnetic ring II 27 retracts with the piston rod to a position close to magnetic ring I 26. Magnetic ring I 26 and magnetic ring II 27 re-engage, and the device returns to normal operation.

[0032] Reference Figure 1 and Figure 7 A C-shaped frame II 35 is fixed on the top of the workbench 1. The opening of the C-shaped frame II 35 faces downward. The C-shaped frame II 35 is located at the end of the conveyor belt 2. The C-shaped frame II 35 is used to install a flipping mechanism. The flipping mechanism is used to flip the lighter body 46 pushed by the push plate II 25, so that the lighter body 46 changes from a horizontal state to a vertical state and is vertically inserted into the placement box 41.

[0033] Reference Figure 7 and Figure 9The flipping mechanism includes a rotating shaft 31 that rotatably passes through a C-shaped frame II 35. The rotating shaft 31 is horizontally positioned, and its two ends are rotatably supported on the two side walls of the C-shaped frame II 35 by bearings. One end of the rotating shaft 31 extends to the outside of the C-shaped frame II 35. A drive motor 32 is fixed to one side of the C-shaped frame II 35. The output shaft of the drive motor 32 is fixedly connected to one end of the rotating shaft 31 by a coupling. The drive motor 32 can be a servo motor or a stepper motor, and its rotation angle is precisely controlled by the control center 47. The flipping mechanism also includes a flipping plate 33 fixed to the outer wall of the rotating shaft 31. The top of the flipping plate 33... In its initial state, the part is flush with the top of the conveyor belt 2. The flip plate 33 corresponds to the position of the push plate II 25, that is, the flip plate 33 is set in the pushing direction of the push plate II 25 and is used to receive the lighter body 46 pushed by the push plate II 25. Two baffles 34 are fixed on the top of the flip plate 33. The two baffles 34 are spaced apart along the width direction of the flip plate 33. The distance between the two baffles 34 is greater than the width of multiple lighter bodies 46 arranged side by side. The two baffles 34 are used to limit the multiple lighter bodies 46 and prevent the lighter bodies 46 from shifting or falling off the flip plate 33.

[0034] Reference Figure 7 and Figure 9 Multiple electric push rods III36 are fixed to the top of the C-shaped frame II35. The cylinders of the multiple electric push rods III36 are all fixed to the top of the C-shaped frame II35. The piston rods of the multiple electric push rods III36 extend vertically downward into the interior of the C-shaped frame II35. A lower push plate 37 is fixed to the bottom end of the piston rods of the multiple electric push rods III36. The lower push plate 37 is horizontally set. When the flip plate 33 rotates to the vertical position, the lower push plate 37 abuts against one side of the flip plate 33. A baffle II39 is fixed to the bottom of the lower push plate 37 away from the flip plate 33. The baffle II39 is vertically set and is used to make the lighter rotate 90° when the flip plate 33 is rotated. When the body 46 is placed vertically, it limits the movement of the lighter body 46. A rubber strip 40 is fixed to the bottom of the push plate 37. The rubber strip 40 is set along the length of the push plate 37 and is used to abut against the top of the vertically placed lighter body 46, pushing the lighter body 46 down and into the placement box 41. The push plate 37 has two clearance openings 38 on the side near the flip plate 33. The positions of the two clearance openings 38 correspond to the positions of the two baffles 34. The clearance openings 38 are used to provide clearance space for the baffles 34 when the flip plate 33 is rotated to the vertical position, so as to avoid interference between the push plate 37 and the baffles 34.

[0035] Reference Figure 1 , Figure 7 and Figure 10A placement box 41 is slidably connected to the top of the workbench 1. The placement box 41 is used to place the lighter body 46. The placement box 41 is set in a groove opened on the top of the workbench 1 and can slide horizontally. The top of the placement box 41 has multiple placement slots. The arrangement of the placement slots matches the stacking requirements of the lighter body 46. The size of the placement slots is adapted to the outer dimensions of the lighter body 46 so that the lighter body 46 can be inserted into the placement slot in a vertical position. One end of the placement box 41 passes through the conveyor belt 2 and extends to the placement box. Inside the placement platform 23, one end of the placement box 41 extends into the internal space of the placement platform 23. An electric push rod IV 42 is fixed inside the placement platform 23. The cylinder of the electric push rod IV 42 is fixed inside the placement platform 23. The piston rod of the electric push rod IV 42 is horizontally set, and one end of it abuts against one side of the placement box 41. The electric push rod IV 42 is used to push the placement box 41 away from the placement platform 23, so that the placement slot above the placement box 41 moves to directly below the flip plate 33, making it easier for the lighter body 46 to be inserted into the placement slot inside the placement box 41.

[0036] Reference Figures 1-10 A control center 47 is fixed on the top of the workbench 1. The control center 47 is electrically connected to the electric actuators IV 42, III 36, II 24, drive motor 32, I 4 and industrial camera 6. The control center 47 is used to receive image signals captured by the industrial camera 6, process and analyze the images, and determine whether there are defects in the lighter body 46. The control center 47 is also used to send control commands to the electric actuators I 4, II 24, III 36, IV 42 and drive motor 32 according to the preset control logic, and control each actuator to act in a predetermined sequence. The control center 47 can be a programmable logic controller or an industrial computer.

[0037] In another embodiment: Refer to Figure 7 and Figure 9 A conductive copper plate 43 is fixedly embedded in the top of the flip plate 33. A carbon fiber brush 44 is fixed in the top of the conductive copper plate 43. Multiple carbon fiber brush 44s are spaced apart along the length of the conductive copper plate 43. The top of the carbon fiber brush 44 protrudes from the upper surface of the flip plate 33. The carbon fiber brush 44 is used to contact the bottom of the lighter body 46 when it is placed on the flip plate 33. A dust collection groove is provided on the side of the carbon fiber brush 44 on the flip plate 33. The dust collection groove is used to collect conductive debris generated by the wear of the carbon fiber brush 44. A conductive grounding wire 45 is connected to the inside of the rotating shaft 31 through a conductive slip ring. One end of the conductive grounding wire 45 extends into the flip plate 33 and is fixedly connected to the conductive copper plate 43. The other end of the conductive grounding wire 45 extends along the axial direction of the rotating shaft 31 and passes through one end of the rotating shaft 31 to ground. The conductive grounding wire 45 can be made of copper wire or tin-plated copper braided wire.

[0038] Specifically, when the lighter body 46 is pushed onto the flip plate 33 by the push plate II 25, and when the rubber strip 40 pushes the lighter body 46 downward, friction is generated between the lighter body 46, the flip plate 33, and the carbon fiber brush 44. The static charge generated by the friction is conducted to the conductive copper plate 43 through the carbon fiber brush 44, and then conducted to the ground through the conductive grounding wire 45. The static charge is released slowly and without sparks, avoiding the generation of instantaneous contact discharge sparks.

[0039] A method for using a vision-based lighter material feeding device includes the following steps: S1, conveyor belt 2 transports lighter body 46 from upstream process to stacking station. During the transport process, lighter body 46 first passes through the screening station in C-frame I3. Industrial camera 6 located at the top of C-frame I3 takes pictures of lighter body 46 on conveyor belt 2. The captured image is transmitted to control center 47. Control center 47 analyzes the image through image processing algorithm to determine whether lighter body 46 has appearance defects. When it is determined to be a defective product, control center 47 controls electric push rod I4 to move. The piston rod of electric push rod I4 pushes push plate I5 to push the defective lighter body 46 away from conveyor belt 2, so that it falls into waste collection box through discharge port 7 and guide inclined plate 9. S2. While the electric push rod I4 drives the push plate I5 to move to remove defective products, the push plate I5 abuts against the arc block 21 on the rotating plate 20. The movement of the push plate I5 causes the rotating plate 20 to rotate around its rotation center. The rotating plate 20 pulls the cable 17, and the cable 17 drives the rotating shaft 12 to rotate through the rotating disk 16. The rotating shaft 12 drives the rotating arm 13 to rotate. The rubber wiper 14 on the rotating arm 13 wipes and cleans the protective glass 11. When the push plate I5 is reset, the rubber wiper 14 is reset under the elastic reset force of the torsion spring 15, waiting for the next cleaning action. This cleaning process utilizes the power when removing defective products, without the need for an additional drive source, and realizes the regular cleaning of the protective glass 11 of the industrial camera 6. S3. The qualified lighter bodies 46 after screening continue to be conveyed forward on the conveyor belt 2. Under the limiting action of the baffle I 30, the qualified lighter bodies 46 are arranged in a row. When the photoelectric sensor detects that the lighter body 46 is in place, it transmits the signal to the control center 47. The control center 47 controls the electric push rod II 24 to extend and wait for pushing. When the qualified lighter body 46 reaches the predetermined position, the piston rod of the electric push rod II 24 extends. Through the magnetic attraction between the magnetic ring II 27 and the magnetic ring I 26, the push plate II 25 is moved, pushing the lighter body 46 laterally from the conveyor belt 2 to the flip plate 33. S4. During the pushing process, if the lighter body 46 becomes stuck with the flip plate 33 or other components, causing increased resistance, when the resistance exceeds the magnetic attraction between the magnetic ring I 26 and the magnetic ring II 27, the magnetic ring I 26 will disengage from the magnetic ring II 27. At this time, the piston rod of the electric push rod II 24 will move during its idle stroke and will no longer push the push plate II 25 forward, thereby preventing the push plate II 25 from continuing to apply pressure to the stuck lighter body 46 and preventing the lighter body 46 from being crushed. S5. After the lighter body 46 is pushed onto the flip plate 33, the drive motor 32 drives the flip plate 33 to rotate 90° through the rotating shaft 31. The flip plate 33 drives the lighter body 46 to flip from a horizontal state to a vertical state. During the flipping process, the stop bar 34 on the flip plate 33 limits the lighter body 46 to prevent it from deviating. After the flipping is completed, the electric push rod Ⅲ 36 pushes the push plate 37 to move downward. The rubber strip 40 at the bottom of the push plate 37 pushes the vertical lighter body 46 downward into the placement slot of the placement box 41. S6. During the process of the lighter body 46 being pushed onto the flip plate 33 and being pushed downwards by the push plate 37, friction is generated between the lighter body 46 and the flip plate 33. The static charge generated by the friction is conducted to the conductive grounding wire 45 through the carbon fiber brush 44 and conductive copper plate 43 embedded on the flip plate 33, and then conducted to the ground through the conductive grounding wire 45. The carbon fiber brush 44 keeps in contact with the lighter body 46, which can release the static charge generated by friction in a timely and continuous manner, avoiding the instantaneous discharge of electric sparks after the static charge accumulates to a certain level. Since there is a possibility of flammable gas escaping at the lighter stacking station, eliminating static sparks is of great significance for ensuring production safety. After the push plate 37 pushes the lighter body 46 into the placement box 41, the electric push rod IV 42 pushes the placement box 41 to move one placement slot spacing, so that the next empty placement slot is aligned with the flip plate 33, waiting for the next stacking.

[0040] Those skilled in the art should understand that the rubber wiper 14, carbon fiber brush filaments 44, magnetic ring I 26, and magnetic ring II 27 in this device are all consumable parts, and their performance will degrade after long-term use. It is recommended that equipment operators regularly inspect and replace these components to ensure the long-term effectiveness of the screening, anti-jamming, and static electricity elimination functions.

[0041] However, as is well known to those skilled in the art, the working principles and wiring methods of electric linear actuators IV 42, III 36, II 24, drive motor 32, I 4, control center 47 and industrial camera 6 are all conventional methods or common knowledge, and will not be described in detail here.

When it is determined to be a defective product, it controls the electric push rod I (4) to drive the push plate I (5) to push the defective product away from the conveyor belt (2) and fall into the waste collection box through the discharge port (7) and the guide inclined plate (9). S2. When the electric push rod I (4) drives the push plate I (5) to remove defective products, the push plate I (5) abuts against the arc block (21) to make the rotating plate (20) rotate. The rotating plate (20) drives the rotating shaft (12) and rotating arm (13) to rotate via the cable (17) and rotating disk (16). The rubber wiper (14) wipes the protective glass (11). After the push plate I (5) is reset, the torsion spring (15) makes the rubber wiper (14) reset. S3. The qualified lighter body (46) is arranged in a row by the baffle I (30). When it reaches the predetermined position, the electric push rod II (24) extends and the magnetic attraction of the magnetic ring II (27) and the magnetic ring I (26) drives the push plate II (25) to push the lighter body (46) laterally onto the flip plate (33). S4. When the lighter body (46) is stuck, when the pushing resistance exceeds the magnetic attraction between the magnet ring I (26) and the magnet ring II (27), the magnet ring I (26) and the magnet ring II (27) disengage, the piston rod of the electric push rod II (24) moves during its idle stroke, and the push plate II (25) stops moving forward. S5. After the lighter body (46) reaches the flip plate (33), the drive motor (32) drives the flip plate (33) to rotate via the rotating shaft (31), flipping the lighter body (46) into a vertical state. The stop bar (34) limits and prevents deviation. After flipping, the electric push rod III (36) pushes the lower push plate (37) down, and the rubber strip (40) pushes the vertical lighter body (46) into the placement slot of the placement box (41). S6. The static charge generated by the friction between the lighter body (46) and the flip plate (33) is conducted to the grounding wire (45) through the carbon fiber brush (44) and the conductive copper plate (43). After the push plate (37) is pushed in, the electric push rod IV (42) pushes the placement box (41) to move one placement slot spacing so that the next empty slot is aligned with the flip plate (33).
