Description

Technical Field

[0001] This invention relates to the technical field of electronic cigarette production, specifically to an electronic cigarette cartridge testing device. Background Technology

[0002] E-cigarette cartridges are consumables used with e-cigarettes, generally consisting of e-liquid, an atomizer core, and a casing. E-liquid is the core ingredient, mainly containing propylene glycol, glycerin, nicotine, and various flavorings. The atomizer core heats and atomizes the e-liquid, forming an inhalable aerosol. The casing protects and contains the e-liquid and the atomizer core. Since the cartridge contains e-liquid, leakage can affect the user experience and even damage the e-cigarette device. Therefore, cartridges need to be inspected using laser detection devices. Laser detection can quickly and accurately scan the surface of the cartridge, detecting not only leakage but also surface defects such as cracks, deformation, and scratches. These defects can affect the performance and safety of the cartridge. Laser detection allows for the timely detection and rejection of substandard products, ensuring product quality. The principle is that surface defects in the e-liquid and cartridge alter the laser's propagation path, thus determining whether the laser path changes and identifying leakage, thereby ensuring the cartridge's seal and appearance integrity.

[0003] In existing laser inspection of e-cigarette cartridges, most methods involve clamping and inspecting the cartridges individually. This inspection method is inefficient and may lead to problems with timely inspection in large-scale e-cigarette production processes, potentially affecting the overall production efficiency of cartridges. Existing technologies can also perform batch inspection of cartridges using a dual-galvanometer scanning system, which mainly consists of two galvanometers and their corresponding drive motors. A galvanometer is an optical element that can quickly and accurately change the reflection angle. The two galvanometers are generally placed perpendicular to each other, with one responsible for scanning in the horizontal direction (X-axis) and the other for scanning in the vertical direction (Y-axis). This allows for laser inspection of cartridges on the entire plane. However, laser inspection of cartridges is greatly affected by the environment. Air temperature, humidity, and impurities in the environment can all affect the accuracy of the inspection. Impurities, in particular, can easily misjudge tiny impurities as serious defects during laser inspection, ultimately causing good cartridges to be treated as defective products. These effects are further amplified in batch inspections that prioritize efficiency.

[0004] Laser inspection of e-cigarette cartridges is a test of the quality of finished e-cigarette cartridges. This process not only screens out defective products to ensure the yield rate, but also investigates the causes of defects. By precisely determining the location of defects with lasers, the source can be traced to find the cause of defects in the production process. However, such precise inspection is difficult to guarantee efficiency, which affects the entire production process. Therefore, the inventor believes that a laser inspection device is needed to conduct batch inspection of e-cigarette cartridges and perform precise inspection of e-cigarette cartridges with quality problems. At the same time, it can also eliminate the influence of impurities as much as possible to prevent intact e-cigarette cartridges from being misjudged due to impurities.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an electronic cigarette cartridge testing device. This invention, through its re-inspection and sorting mechanism, solves the problems in the above-mentioned solutions where the laser aperture is too large during centralized testing, resulting in insufficient detection quality and significant environmental influence, making it impossible to accurately determine the location and size of defects.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An electronic cigarette cartridge testing device includes a testing mechanism, which includes a belt conveyor and a concave arc section belt conveyor. Several placement platforms are provided on the belt of the belt conveyor. A testing lifting platform is provided between the belt conveyor and the concave arc section belt conveyor. A loading platform is fixed to the telescopic end of the testing lifting platform. A deflection motor is fixed above the loading platform. A connecting plate frame is also rotatably connected to the loading platform. The power shaft of the deflection motor is fixedly connected to the connecting plate frame. A clamping mechanism is provided at the end of the connecting plate frame away from the loading platform. The testing mechanism also includes a main support frame, on which a laser generator is fixed. The laser generator has a dual-mirror scanning system at its probe end. A laser receiver is also fixed on the main support frame, and the laser receiver is positioned opposite to the laser generator.

[0008] Preferably, the clamping mechanism includes an end cap fixed to the end of the connecting plate frame away from the loading platform. Main beams are fixed on both sides of the lower surface of the end cap. A central shaft is fixed on the opposite face of the two main beams. Several support arm groups are movably connected to the outer periphery of the central shaft. Each support arm group is provided with two support arms. The two support arms in the same support arm group are threaded to the same threaded rod at the same end. The threaded rod is a double-ended stud. The two support arms in the same support arm group are mirror images of the two opposite threads on the threaded rod. A housing is provided on the outer periphery of the threaded rod. An adjusting motor is fixed inside the protective housing. The threaded rod is fixedly connected to the power shaft of the adjusting motor. Several clamping parts are provided on the opposite face of the two support arms in the same support arm group. The end of the support arm group away from the threaded rod is rotatably connected to the same connecting shaft. The support arm assembly is also vertically equipped with several support rod assemblies. Each support rod assembly has two support rods. The same end of the support rods in the same support rod assembly is threaded to a threaded rod II. The threaded rod II is a double-ended stud. The two support rods in the same support rod assembly are mirror images of the two opposite threads of the threaded rod II. The outer periphery of the threaded rod II is also equipped with a housing II. An adjusting motor II is fixed inside the housing II. One end of the threaded rod II is fixed to the power shaft of the adjusting motor II. Several clamping parts II are mirror images of the outer periphery of the two support rods in the same support rod assembly.

[0009] Preferably, a lead screw motor is fixed on one of the main beams, one end of the lead screw of the lead screw motor is rotatably connected to one end of a connecting shaft, and the end of the connecting shaft away from the lead screw motor lead screw is rotatably connected to a limit rod, which is movably connected to another main beam.

[0010] Preferably, a re-inspection and sorting mechanism is also provided on one side of the main support frame. The re-inspection and sorting mechanism includes a re-inspection lifting platform. A re-inspection chamber is fixed at the lifting end of the re-inspection lifting platform. A cleaning hopper is connected through the top of the re-inspection chamber. A cleaning roller is installed inside the cleaning hopper. An electric control gate is also provided at the connection end between the cleaning hopper and the re-inspection chamber. The two side walls opposite to the re-inspection chamber are respectively connected and fixed with a light-shielding pipe one and a light-shielding pipe two. There are also two material drop troughs at the bottom of the re-inspection chamber, and each of the two material drop troughs is equipped with an electric control gate.

[0011] Preferably, the re-inspection chamber is equipped with a temperature and humidity control device on its side wall. The re-inspection chamber is connected to the cleaning hopper at a conical port. A negative pressure suction cup is located directly below the conical port. A drive shaft is rotatably connected inside the re-inspection chamber. A rotating motor is fixed on the outer wall of the re-inspection chamber. The power shaft of the rotating motor passes through the side wall of the re-inspection chamber and is fixedly connected to the drive shaft. A hydraulic telescopic rod is fixed at the end of the drive shaft away from the rotating motor. The negative pressure suction cup is fixed to the telescopic end of the hydraulic telescopic rod. A vacuum pump is also fixed on the outer wall of the re-inspection chamber. The re-inspection sorting mechanism also includes a connecting pipe. The negative pressure suction cup is connected to the vacuum pump through the connecting pipe. A fan is also provided on one side of the re-inspection lifting platform. A dust suction pipe is fixed through the fan port. The end of the dust suction pipe away from the fan is connected to the re-inspection chamber.

[0012] Preferably, a waste conveyor and a return conveyor are also installed below the two material discharge troughs.

[0013] Preferably, there are several cleaning rollers, and the cleaning rollers are connected by a transmission wheel set. A cleaning motor is also provided on the side wall of the cleaning hopper. The power shaft of the cleaning motor passes through the side wall of the cleaning hopper and is fixedly connected to one of the cleaning rollers.

[0014] Preferably, the laser generating equipment and the dual-galvanometer scanning system are provided in two sets, one set is horizontal and the other set is tilted. When performing laser detection, the tilted set is parallel to the clamping mechanism holding the part.

[0015] Compared with the prior art, the present invention provides an electronic cigarette cartridge detection device, which has the following beneficial effects: This invention, through its specially designed detection mechanism, involves activating a re-inspection lifting platform to raise the clamping mechanism. Simultaneously, the lead screw motor is adjusted to horizontally position the support arm assembly. Then, the deflection motor is activated, driving the clamping mechanism to rotate. By controlling the adjustment motors one and two on the support arm and support rod assemblies, the support arm and support rod assemblies are opened and closed. The clamping is then performed by clamping components one and two. After clamping, the adjustment motors rotate to move the cartridge to be tested to the side of the laser generator for testing. This solves the problem of low detection efficiency in related solutions, which can only test cartridges individually at a time.

[0016] This invention utilizes a clamping mechanism and a detection mechanism. During detection, the screw motor rotates, pushing the connecting shaft downwards. At this time, the originally horizontally positioned support arm assembly tilts, and the fixedly clamped tobacco cartridges are arranged in a staggered manner. Neither the horizontal nor the tilted surfaces opposite the laser generator obstruct it. Furthermore, there is no overlap of tobacco cartridges in the laser generator's field of view. The second clamping component is made of a light-transmitting material, which does not affect normal laser penetration detection. This solves the problem of limited laser detection angles in related solutions, which prevents multi-angle detection of tobacco cartridges. The staggered detection layout further improves the accuracy of the detection.

[0017] This invention utilizes a re-inspection and sorting mechanism. During batch testing, defective e-cigarette cartridges are first cleaned of impurities by a cleaning roller, then fixed by a negative pressure suction cup. The entire re-inspection chamber is raised, aligning the first and second light-shielding pipes with the laser generator and laser receiver. The electrical control gates on the material chute and cleaning hopper are closed. The temperature and humidity control device is then adjusted to optimize the internal temperature and humidity for laser detection. After more detailed testing, the specific location and details of the cartridge damage are determined, thus identifying the cause of the problem. After testing, a rotating motor drives a hydraulic telescopic rod, allowing good cartridges to flow out from one of the material chutes and be transported back to the concave arc belt conveyor for normal production via a return conveyor. Defective products with quality issues flow out from the other material chute and are transported by a waste conveyor for further processing. This solves the problems of insufficient precision in centralized testing due to the large laser aperture, significant environmental influences, and inability to accurately determine the location and size of defects in the aforementioned solutions.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an electronic cigarette cartridge detection device.

[0028] Example 1 like Figure 1 and Figure 2 As shown, an electronic cigarette cartridge testing device includes a testing mechanism 1, which includes a belt conveyor 11 and a concave arc section belt conveyor 17. Several placement platforms 111 are provided on the conveyor belt of the belt conveyor 11. A testing lifting platform 12 is provided between the belt conveyor 11 and the concave arc section belt conveyor 17. A loading platform 121 is fixed to the telescopic end of the testing lifting platform 12. A deflection motor 122 is fixed above the loading platform 121. A connecting plate frame 123 is also rotatably connected to the loading platform 121. The power shaft of the deflection motor 122 is fixedly connected to the connecting plate frame 123. A clamping mechanism 2 is provided at the end of the connecting plate frame 123 away from the loading platform 121. The belt conveyor 11 is used to transport the completed e-cigarette cartridges that need to be tested in the production process. The placement platform 111 can arrange the e-cigarette cartridges evenly. The specifications of the placement platform 111 are compatible with the parts clamped by the subsequent clamping mechanism 2, which facilitates the clamping and fixing of the parts by the subsequent clamping mechanism 2. The testing lifting platform 12 is mainly used to drive the clamping mechanism 2 to perform clamping and testing. The testing lifting platform 12 rises, driving the clamping mechanism 2 to rise. The deflection motor 122 rotates, driving the clamping mechanism 2 to rotate. Finally, the clamping mechanism 2 is placed above the placement platform 111 to clamp the e-cigarette cartridges. The cartridges are then tested on the laser testing component. Finally, the concave arc section belt conveyor 17 transports the tested e-cigarette cartridges in batches, controlling their movement, lifting, and placement.

[0029] The testing mechanism 1 also includes a main support frame 13, on which a laser generator 14 is fixed. The laser generator 14 has a dual-mirror scanning system 15 at its probe end. A laser receiver 16 is also fixed on the main support frame 13. The laser receiver 16 is arranged opposite to the laser generator 14.

[0030] The laser detection setup primarily uses a laser generator 14 to generate a laser for scanning, followed by a dual-mirror scanning system 15, and then a laser receiver 16 in conjunction with computer image processing technology to detect quality issues in the cartridge itself. This is an existing device and will not be described in detail here.

[0031] Example 2 like Figure 1 , Figure 6 and Figure 7As shown, the present invention provides another technical solution based on Embodiment 1. The clamping mechanism 2 includes an end cap 21 fixed to the end of the connecting plate frame 123 away from the loading platform 121. Main beams 22 are fixed on both sides of the lower surface of the end cap 21. A central shaft 23 is fixed on the opposite face of the two main beams 22. Several support arm groups 24 are movably connected to the outer periphery of the central shaft 23. Each support arm group 24 is provided with two support arms. The two support arms in the same support arm group 24 are threaded to the same threaded rod 241 at the same end. The threaded rod 241 is a double-ended stud. The two support arms in the same support arm group 24 are mirror images of the two opposite threads on the threaded rod 241. A housing 242 is provided on the outer periphery of the threaded rod 241. An adjusting motor 243 is also fixed inside the protective housing. The threaded rod 241 is fixed to the power shaft of the adjusting motor 243. The two support arms in the same support arm group 24 are connected, and each of the two support arms has several clamping parts 244 on its opposite face. The end of the support arm group 24 away from the threaded rod 241 is rotatably connected to the same connecting shaft 25. Several support rod groups 28 are also vertically arranged on the support arm group 24. Each support rod group 28 has two support rods. The same end of the support rods in the same support rod group 28 is threaded to a threaded rod 281. The threaded rod 281 is a double-ended stud. The two support rods on the same support rod group 28 are mirror images of the two opposite threads of the threaded rod 281. The outer periphery of the threaded rod 281 is also provided with a housing 282. An adjusting motor 283 is fixed inside the housing 282. One end of the threaded rod 281 is fixed to the power shaft of the adjusting motor 283. Several clamping parts 284 are mirror images of the outer periphery of the two support rods on the same support rod group 28.

[0032] like Figure 6 and Figure 7 As shown, a lead screw motor 26 is fixed on one of the main beams 22. One end of the lead screw of the lead screw motor 26 is rotatably connected to one end of the connecting shaft 25. The end of the connecting shaft 25 away from the lead screw motor 26 is rotatably connected to a limit rod 27. The limit rod 27 is movably connected to the other main beam 22.

[0033] The mechanism is mainly divided into side wall clamping and end clamping. End clamping is mainly achieved through the support arm assembly 24 and the clamping element 244 set on it. When clamping is required, the adjusting motor 243 will rotate, driving the threaded rod 241 to rotate, thereby causing the two support arms of the support arm assembly 24 to move towards each other to clamp the tobacco cartridge. The clamping of the side wall of the tobacco cartridge is roughly the same, with the clamping element 284 clamping it through the support rod assembly 28. The device is equipped with multiple sets of support arm assemblies 24 and multiple sets of support rod assemblies 28, and multiple clamping elements 244 and clamping elements 284 are set on the support arm assemblies 24 and support rod assemblies 28. A tilted laser generator 14 can be placed parallel to the laser. At this point, all the fixedly clamped tobacco cartridges will be staggered, with no obstruction from the horizontal or tilted surfaces opposite the laser generator 14. Simultaneously, there is no overlap of tobacco cartridges within the viewing angle of the laser generator 14. After adjustment, the tobacco cartridges are laser-detected using the laser generator 14. The laser generator 14 scans the entire tobacco cartridge using a dual-galvanometer scanning system 15. The dual-galvanometer scanning system 15 is a laser scanning device mainly composed of two galvanometers and corresponding drive motors. A galvanometer is a device capable of quickly and accurately changing the reflection angle. The optical elements consist of two galvanometers, typically placed perpendicularly to each other. One galvanometer is responsible for scanning in the horizontal direction (X-axis), and the other for scanning in the vertical direction (Y-axis). During laser scanning detection, the motor 243 rotates, driving the threaded rod 241 to rotate, which in turn causes the clamping arm mounted on the threaded rod 241 to move backward, thus disengaging the clamping member 244. At this point, the clamping is only held in place by the second clamping member 284. The laser generator 14 then performs a more comprehensive scan of the cartridge, preventing the clamping member 244 from obstructing the end of the cartridge and affecting the detection accuracy. 4. After scanning is complete, the laser receiving device 16 receives the emitted laser signal. The principle is that defects on the surface of the e-liquid and the cartridge alter the laser's propagation path. This allows the device to determine if the laser path has changed, thus identifying whether the cartridge is leaking and verifying its seal and overall integrity. (Details omitted here.) After receiving feedback, the laser receiving device 16 transmits the signal to the regulating motors 243 and 283 via a signal transmission device. This causes the support arm assembly 24 to re-clamp the cartridge, and similarly, the clamping rod assembly moves the clamping member 284 away from the cartridge. The device then scans again using the laser generating device 14. Similarly, as mentioned above, to prevent the clamping part 284 from obstructing the accuracy of laser detection, the results of the two scans are summarized and integrated using imaging technology to ultimately detect the original appearance of the cartridge. The cartridge is then analyzed and judged. When a problem is detected in the cartridge, the signal is transmitted back to the adjusting motor 1 243 and adjusting motor 283 via the signal transmission device. Then, the support rod group 28 and support arm group 24 at the position of the cartridge are adjusted synchronously, so that the clamping part 1 244 at the end and the clamping part 284 on the periphery are completely detached from the cartridge, and finally the cartridge falls into the re-inspection and sorting mechanism 3 for detailed inspection.

[0034] Example 3 like Figure 2 , Figure 3 and Figure 4As shown, the present invention provides another technical solution based on Embodiment 1 and Embodiment 2. A re-inspection and sorting mechanism 3 is also provided on one side of the main support frame 13. The re-inspection and sorting mechanism 3 includes a re-inspection lifting platform 31. A re-inspection cavity 32 is fixed at the lifting end of the re-inspection lifting platform 31. A cleaning hopper 33 is connected through the top of the re-inspection cavity 32. A cleaning roller 331 is provided inside the cleaning hopper 33. An electric control gate 332 is also provided at the connection end between the cleaning hopper 33 and the re-inspection cavity 32. The two side walls opposite to the re-inspection chamber 32 are respectively connected and fixed with a light-shielding pipe 38 and a light-shielding pipe 381. The bottom of the re-inspection chamber 32 is also provided with two material drop troughs 39, and each of the two material drop troughs 39 is equipped with an electric control gate 332.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, a temperature and humidity control device 34 is provided on the side wall of the re-inspection chamber 32. The port connecting the re-inspection chamber 32 to the cleaning hopper 33 is a conical port 35. A negative pressure suction cup 36 is provided directly below the conical port 35. A drive shaft 361 is also rotatably connected inside the re-inspection chamber 32. A rotating motor 362 is fixed on the outer wall of the re-inspection chamber 32. The power shaft of the rotating motor 362 passes through the side wall of the re-inspection chamber 32 and is fixedly connected to the drive shaft 361. A liquid is fixed at the end of the drive shaft 361 away from the rotating motor 362. The hydraulic telescopic rod 363 is fixed to the telescopic end of the hydraulic telescopic rod 363. A vacuum pump 364 is also fixed on the outer wall of the re-inspection chamber 32. The re-inspection and sorting mechanism 3 also includes a connecting pipe 365. The negative pressure suction cup 36 is connected to the vacuum pump 364 through the connecting pipe 365. A fan 37 is also provided on one side of the re-inspection lifting platform 31. A dust suction pipe 371 is fixed through the port of the fan 37. The end of the dust suction pipe 371 away from the fan 37 is connected to the re-inspection chamber 32.

[0036] like Figure 3 As shown, a waste conveyor 391 and a return conveyor 392 are respectively installed below the two material discharge chute 39.

[0037] The re-inspection lifting platform 31 is mainly used to lift the re-inspection chamber 32, so that the first light-shielding pipe 38 and the second light-shielding pipe 381 are aligned with the laser generator 14 and the laser receiver 16, thereby shielding the interference of external ambient light and improving the detection quality. The cleaning hopper 33 and the cleaning roller 331 are used to receive the cigarette cartridges dropped from the clamping mechanism 2 and perform surface cleaning to remove the influence of impurities. Then, they fall through the conical port 35 to the negative pressure suction cup 36 for adsorption and fixation. The cleaning hopper 33 is also equipped with an electric control gate 332. After the cigarette cartridge enters the re-inspection chamber 32, the electric control gate 332 is closed to make the entire re-inspection chamber 32 as airtight as possible. Then, the internal ambient temperature and humidity can be adjusted to the most suitable laser detection temperature by the temperature and humidity control device 34 to further improve the detection quality and accuracy. The re-inspection chamber 32 is also equipped with a fan 37, which can adsorb and remove dust and impurities floating in the workshop during daily inspection. This device uses negative pressure suction. The disc 36 is controlled by a vacuum pump 364 outside the re-inspection chamber 32 and is connected to a connecting pipe 365. At the same time, the adsorption and suspension detection of the e-cigarette cartridges are controlled by a hydraulic telescopic rod 363. After laser re-inspection, damage or impurities are identified, the specific location of the damaged part is measured, and the source is traced to find out whether it is a problem with the yield rate, a defect caused by mold production, or simply a misjudgment caused by impurities in the first inspection. After the inspection is completed, the hydraulic telescopic rod 363 is rotated by rotating the motor 362. Good e-cigarette cartridges that were misjudged in the first inspection flow out from one of the drop troughs 39 and are transported back to the concave arc section belt conveyor 17 by the return conveyor 392 for normal production. Defective products with quality problems flow out from the other drop trough 39 and are transported to the waste conveyor 391 for further processing. The drop trough 39 is also equipped with an electric control gate 332, which is also in a closed state during the laser inspection process.

[0038] like Figure 3 As shown, there are several cleaning rollers 331, and the cleaning rollers 331 are connected by a transmission wheel set. A cleaning motor is also provided on the side wall of the cleaning hopper 33. The power shaft of the cleaning motor passes through the side wall of the cleaning hopper 33 and is fixedly connected to one of the cleaning rollers 331.

[0039] The drive roller assembly mainly consists of drive rollers and a drive belt set on the outer periphery of the drive rollers. Except for the cleaning rollers 331 at the beginning and end, which are equipped with one drive roller, the other cleaning rollers 331 are equipped with two drive rollers. The drive rollers are connected in pairs through the drive rollers and the drive belt, and the cleaning motor generates power to drive them to rotate, thereby cleaning the surface of the e-cigarette cartridge.

[0040] like Figure 1 and Figure 2As shown, the laser generating device and the dual galvanometer scanning system 15 are provided in two sets, one set is horizontal and the other set is tilted. When performing laser detection, the tilted set is parallel to the clamping mechanism 2 that clamps the part.

[0041] The system is equipped with two laser detection components to enable multi-angle detection, which greatly improves the accuracy of the detection. By tilting the clamping parts on the clamping mechanism 2, a set of tilted parts is made parallel to the clamping parts of the clamping mechanism 2, thus enabling better detection. At the same time, this solution does not affect the detection effect in the horizontal direction.

[0042] Working principle: When using this device, production line workers place the cartridges to be tested onto the placement platform 111 on the belt conveyor 11 for conveying and testing. Then, the re-inspection lifting platform 31 is activated to raise the clamping mechanism 2. At the same time, the screw motor 26 is adjusted so that the support arm assembly 24 is set horizontally. Then, the deflection motor 122 is activated to drive the clamping mechanism 2 to rotate, so that it is directly above the placement platform 111. Then, it is controlled to fall back. By controlling the adjusting motors 243 and 283 on the support arm assembly 24 and support rod assembly 28, the support arm assembly 24 and support rod assembly 28 are opened and closed. Then, the clamping parts 244 and 284 clamp the cartridges. After clamping, the cartridges are discharged. The adjustment motor rotates to move the cartridges to be tested to one side of the laser generator 14. Then, the lead screw motor 26 is rotated to push the connecting shaft 25 downward. At this time, the originally horizontally set support arm group 24 will be tilted, and the fixedly clamped cartridges will be arranged in a staggered manner. The sides of the cartridges in the horizontal and tilted directions do not obstruct the laser generator 14. At the same time, there is no overlap of all cartridges in the field of view of the laser generator 14. With the cooperation of the dual galvanometer scanning system 15, laser detection is performed on all cartridges in the group. The dual galvanometer scanning system 15 is a device for laser scanning, which mainly consists of two galvanometer mirrors and corresponding drive motors. A galvanometer mirror is an optical element that can quickly and accurately change the reflection angle. It is usually thin and coated with a metal film with high reflectivity. The two galvanometers are generally placed perpendicular to each other. One is responsible for scanning in the horizontal direction (X-axis) and the other is responsible for scanning in the vertical direction (Y-axis). When a defective cartridge is detected, the support arm group 24 and the support rod group 28 at the position of the cartridge are adjusted at the same time, so that the end clamping part 244 and the peripheral clamping part 284 are completely detached from the cartridge. Finally, the defective cartridge falls into the re-inspection and sorting mechanism 3 for detailed inspection.

[0043] The tobacco cartridge first passes through the cleaning hopper 33, where it is cleaned of impurities by the cleaning roller 331. Then, it falls from the conical port 35 into the re-inspection chamber 32, where it is adsorbed and fixed by the negative pressure suction cup 36. This negative pressure suction cup 36 is controlled by a vacuum pump 364 outside the re-inspection chamber 32 and is connected via a connecting pipe 365. The negative pressure suction cup 36 is adjustable via a hydraulic telescopic rod 363, allowing it to extend upwards to align with the conical port 35, catching the adsorbed tobacco cartridge. The cartridge is then suspended, and the re-inspection lifting platform 31 is activated, raising the entire re-inspection chamber 32. This aligns the first and second light-shielding pipes 38 and 381 with the laser generator 14 and laser receiver 16, thus shielding against ambient light interference and improving inspection quality. The electrical control gates 332 on the material drop chute 39 and the cleaning hopper 33 are then closed, sealing the entire re-inspection chamber 32. Then, the internal temperature and humidity are adjusted to the optimal temperature for laser detection by the temperature and humidity control device 34, further improving the detection quality and accuracy. The temperature and humidity control device 34 can be the Miaoxin TH11O intelligent temperature and humidity controller. At this time, the cartridges are re-inspected. After more detailed inspection, the specific location and details of the cartridge damage are finally determined, so as to determine the cause of the problem and whether it does not affect normal use or needs to be recycled. After the inspection is completed, the hydraulic telescopic rod 363 is rotated by rotating the motor 362. Good cartridges will flow out from one of the discharge chute 39 and be transported back to the concave arc section belt conveyor 17 by the return conveyor 392 for normal production. Defective products with quality problems will flow out from the other discharge chute 39 and be transported by the waste conveyor 391 for further processing.
