Description

Technical Field

[0001] This invention relates to the field of drum inspection technology, specifically to a drum forming inspection device for dry cleaning machines. Background Technology

[0002] As an essential piece of modern garment care equipment, the performance and lifespan of the drum—the core working component of a dry cleaning machine—directly determine the overall washing effect, operating noise, vibration level, and long-term reliability of the machine. The drum is typically made from high-strength, corrosion-resistant stainless steel sheets through multiple processes including rolling, welding, shaping, and polishing, ultimately forming a precise cylindrical or conical structure. The quality of its forming during the drum's manufacturing process is of paramount importance.

[0003] However, existing dry cleaning machine drum forming detection devices still have the following problems:

[0004] 1. When existing detection devices detect eccentricity of the roller, it is difficult to identify it with the naked eye or ordinary sensors, and it is not easy to clearly see whether the roller is eccentric or slightly deformed.

[0005] 2. Existing detection devices rely on the subjectivity of manual visual inspection, which can easily lead to misjudgment of the specifications of holes on the roller surface;

[0006] 3. When the existing detection device moves the roller, it relies on mechanical grippers or fixing fixtures, which may cause the roller to be deformed by pressure, affecting the detection results. Summary of the Invention

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] Please see Figures 1-12 As shown, a dry cleaning machine drum forming detection device includes a worktable 1. A deformity detection component 2 is installed on the top surface of the worktable 1 to check the eccentricity or deformation of the drum. The deformity detection component 2 includes a developing mechanism that makes the eccentricity or deformation of the drum more obvious. A drum conveying component 3 is installed on one side of the worktable 1 to transport the drum. The drum conveying component 3 includes a station shifting mechanism for precisely switching the drum to different work positions. A fixed-axis rotation component 4 is installed on the top surface of the worktable 1 to rotate the drum on a fixed axis. A contact profilometer 5 is installed on the top surface of the worktable 1. A discharge component 6 for classifying the drum is installed on the side of the worktable 1 away from the drum conveying component 3. A hole measuring component 7 for detecting holes on the surface of the drum is installed on the top surface of the worktable 1. The drum conveying component 3, deformity detection component 2, hole measuring component 7, contact profilometer 5, and discharge component 6 are arranged sequentially. The developing mechanism and the fixed-axis rotation component 4 are located on opposite sides of the deformity detection component 2, and the station shifting mechanism is located above the worktable 1.

[0045] To address the technical problem of roller deformity detection, this invention employs a deformity detection component 2 that includes a roller positioning mechanism. This mechanism includes a first positioning turntable 21 installed inside a worktable 1. A placement plate 22 is fixedly connected to the output end of the first positioning turntable 21. A positioning cone 24 is fixedly connected to the top surface of the placement plate 22. An annular groove is formed on the top surface of the placement plate 22, and a magnetic ring 23 is embedded inside the groove. The outer diameter of the positioning cone 24 is the same as the inner diameter of the magnetic ring 23. A first motor 26 is installed inside the worktable 1, and the output shaft of the first motor 26... A positioning rod 25 is fixedly connected and rotatably connected to the worktable 1 via a bearing. A vision sensor 27 is installed at the top of the positioning rod 25 via a connecting column. The position of the vision sensor 27 is on the same axis as the axis of the placement plate 22. When positioning is required before the roller is inspected, the roller and the placement plate 22 are aligned on the same axis, and then the roller is placed on the surface of the positioning cone 24. The bottom end of the roller will contact the second positioning turntable 28, and the roller will be positioned by the magnetic force of the second positioning turntable 28, thus achieving the positioning of the roller before inspection.

[0046] When the roller needs to be inspected after positioning, the geared motor inside the first positioning turntable 21 is started, and the placement plate 22 will drive the roller to rotate. Then, the first motor 26 is connected to an external power source and started. The first motor 26 will indirectly drive the vision sensor 27 to rotate around the positioning rod 25 as the axis until the vision sensor 27 rotates directly above the roller and is on the same axis as the roller. This completes the adjustment of the position of the vision sensor 27. Then, the vision sensor 27 can be used to observe whether the roller is eccentric or deformed during rotation.

[0047] It should be noted that the vision sensor 27 is a CCD camera, which is a digital camera that uses a charge-coupled device (CCD) as an image sensor. Therefore, the CCD camera converts the optical scene into a digital image signal and outputs a raw pixel matrix. Then, in conjunction with subsequent software algorithms, image recognition is achieved. In addition, the surface of the vision sensor 27 is equipped with an ultraviolet lamp to supplement the fluorescence. Electrons in the fluorescence molecules absorb light of a specific wavelength (usually ultraviolet or short-wave visible light) and transition from the ground state to the excited state.

[0048] To address the technical problem of inconspicuous detection of roller deformities, this invention employs a developing mechanism comprising a second positioning turntable 28 installed inside a worktable 1. A second support 213 is fixedly connected to the output end of the second positioning turntable 28. A connecting pipe 215 is slidably connected to the top of the second support 213 via a positioning cylinder. A sponge 216 is sleeved on the liquid outlet end of the connecting pipe 215 away from the second support 213. A second electric push rod 214 is mounted on the top of the second support 213. The output end of the second electric push rod 214 is fixedly connected to the connecting pipe 215 via a connector. A protective shell 217 is fixedly connected to the side of the second support 213 facing the sponge 216. The developing mechanism also includes a cleaning mechanism disposed on the top surface of the output end of the second positioning turntable 28. The cleaning mechanism includes a first support 29 fixedly connected to the top surface of the output end of the second positioning turntable 28. A sliding frame is slidably connected to the top surface of the first support 29, and a mold cleaner is placed inside the sliding frame. The detergent tank 210 has a first electric push rod 212 mounted on the top surface of the first bracket 29. The output shaft of the first electric push rod 212 is fixedly connected to the sliding frame. An air gun 211 is fixedly connected to one side of the first bracket 29 by bolts. Before testing after the roller is installed, in order to make the edge of the roller more obvious when it rotates, the reduction motor inside the second positioning turntable 28 is started, so that the first bracket 29 faces the roller. Then, the first electric push rod 212 is connected to an external power source and started. The first electric push rod 212 will push the sliding frame, which will drive the mold cleaning agent tank 210 inside to move towards the roller until one end of the first bracket 29 limits the mold cleaning agent tank 210. At this time, the nozzle of the mold cleaning agent tank 210 is directly above the edge of the roller. As the mold cleaning agent tank 210 is squeezed, the liquid inside the mold cleaning agent tank 210 is sprayed towards the edge of the roller to wash away the dirt on the edge of the roller.

[0049] While rinsing away dirt, the air gun 211 is connected to an external air pump. The air is sprayed through the exhaust port of the air gun 211 towards the edge of the roller, blowing off the cleaning agent remaining on the surface of the roller and drying the edge of the roller.

[0050] After cleaning is completed, the reduction motor inside the second positioning turntable 28 is started, causing the output end to rotate 180 degrees, so that the second bracket 213 faces the drum. Then, the second electric push rod 214 is connected to an external power source and started. The output shaft of the second electric push rod 214 will drive the connecting pipe 215 to move towards the drum through the connector. The sponge 216 will slide out from the inside of the protective shell 217 until the sponge 216 is located at the edge of the drum. Then, through an external centrifugal pump, the fluorescent agent is sprayed into the inside of the sponge 216 through the connecting pipe 215. The fluorescent agent will seep out through the sponge 216 and be applied to the edge of the drum by the rotation of the drum. The fluorescent agent makes the edge of the drum more obvious when the drum is inspected.

[0051] To solve the technical problems of roller conveying, the present invention employs a roller conveying assembly 3, which includes a conveying mechanism 31 installed on one side of the workbench 1. A first photoelectric sensor transmitter 32 is installed on one side of the support of the conveying mechanism 31, and a first photoelectric sensor receiver 33 is installed on the other side of the support of the conveying mechanism 31. The first photoelectric sensor transmitter 32 and the first photoelectric sensor receiver 33 are on the same axis. When it is necessary to convey the roller, the roller is placed on the track surface of the conveying mechanism 31, and then the motor inside the conveying mechanism 31 is started, so that the roller can move towards the workbench 1. After moving to a certain distance, the roller will block the light emitted by the first photoelectric sensor transmitter 32, so that the first photoelectric sensor receiver 33 cannot receive it. Then the motor inside the conveying mechanism 31 will stop running, thus determining the initial position of the roller before detection.

[0052] To address the technical issues related to the roller transfer station, this invention employs a station transfer mechanism comprising a support frame 34. A second motor 37 is mounted on the top surface of the support frame 34. The output shaft of the second motor 37 is fixedly connected to a lead screw 38 via a coupling. The lead screw 38 is rotatably connected to the support frame 34 via a vertical bearing seat. A positioning block 36 is threaded onto the surface of the lead screw 38. Two first guide rails 35 are symmetrically mounted on the top surface of the support frame 34. The positioning block 36 is slidably connected to the first guide rails 35 via a slider. A third electric push rod 39 is mounted on the top surface of the positioning block 36. The output shaft passes through the surface of the positioning block 36 and is fixedly connected to a connecting frame 310. A fourth electric push rod 311 is installed inside the connecting frame 310. A limiting cylinder 316 is fixedly connected to the bottom surface of the connecting frame 310. A connecting plate 312 is installed inside the limiting cylinder 316. The output shaft of the fourth electric push rod 311 passes through the bottom surface of the connecting frame 310 and is fixedly connected to the connecting plate 312. Several limiting grooves 313 are evenly distributed on the surface of the limiting cylinder 316. A connecting rod is slidably connected inside each limiting groove 313, and one end of the connecting rod is connected to the connecting plate 312 via a bearing seat. The connecting rod is rotatably connected to an extrusion block 314 via a bearing seat. Each extrusion block 314 has a positioning friction ring 315 fitted on its surface. When the roller needs to be moved to a different position, the second motor 37 is connected to an external power source and started. The positioning block 36 slides on its surface due to the rotation of the lead screw 38 until the limiting cylinder 316 and the roller are on the same axis. Then, the third electric push rod 39 is connected to an external power source and started. The connecting frame 310 drives the limiting cylinder 316 to move towards the roller until the extrusion block 314 is inserted into the roller. The fourth electric push rod 311 is connected to an external power source and then started. The connecting plate 312 moves downward inside the limiting cylinder 316. When the connecting plate 312 moves, several connecting rods will rotate on the surface of the connecting plate 312 due to the limiting groove 313. This causes the extrusion block 314 to move closer to each other towards the inner wall of the roller until it is in contact with the roller. The roller is limited by friction. Then, by retracting the third electric push rod 39, the roller is lifted. Then, by rotating the lead screw 38, the positioning block 36 drives the roller to move, thus realizing the transfer of the roller's working position.

[0053] To prevent the roller from deforming when the inner wall of the roller is squeezed, a positioning friction ring 315 is fitted on the surface of the extrusion block 314, so that the pressure when in contact with the roller is annular, thereby increasing the contact area.

[0054] The positioning friction ring 315 can be made of silicone, leather or soft PVC, preferably rubber.

[0055] To solve the technical problem of rotating the roller structure, this invention employs a fixed-axis rotating assembly 4, including a first cylinder 41 mounted on the top surface of the worktable 1. A rotary cylinder 42 is fixedly connected to the piston end of the first cylinder 41. A clamping cylinder 44 is fixedly connected to the output shaft of the rotary cylinder 42. A fixed shell 43 is rotatably connected to the surface of the clamping cylinder 44 via bearings. The fixed shell 43 is slidably connected to the worktable 1 via a guide rod. Both clamping rods of the clamping cylinder 44 are fixedly connected to clamping plates 45, and the two clamping plates 45 are located on both sides of the positioning cone 24. When one end of the roller has been inspected and the other end needs to be inspected, The clamping cylinder 44 is connected to an external air pump and started. The two clamping plates 45 move closer to each other until they clamp the roller. Then, the first cylinder 41 is connected to an external air pump and started. The first cylinder 41 indirectly drives the clamping cylinder 44 to move upward through the fixed shell 43, thus pulling the roller out from the surface of the positioning cone 24. Then, the rotating cylinder 42 is connected to an external air pump and started. The rotating cylinder 42 drives the roller to rotate 180 degrees through the clamping cylinder 44, thus achieving the rotation of the roller. Then, the piston of the first cylinder 41 is retracted, so that the roller is put back onto the surface of the positioning cone 24, thus achieving the repositioning of the roller.

[0056] When one end of the roller is slightly deformed, and it is still fitted onto the surface of the positioning cone 24, the positioning cone 24 will squeeze the deformed part into a qualified shape. However, after flipping, when the deformed end is not limited at the upper end, the deformed part will spring back due to the material of the roller itself, so that the deformed roller can still be detected during inspection.

[0057] To address the technical problem of detecting holes on the surface of a roller, this invention employs a hole-measuring assembly 7. This assembly includes a third positioning turntable 711 located inside a workbench 1, with the third positioning turntable 711 situated on one side of the first roller positioning mechanism. The two positioning mechanisms are on the same axis. A fixed-axis rotating assembly 4 is located on one side of the third positioning turntable 711. Two fifth electric push rods 71 ​​are symmetrically mounted on both sides of the third positioning turntable 71 via brackets. The output shaft of each fifth electric push rod 71 is fixedly connected to a limit frame 72. A second guide rail 73 is mounted on the top surface of the workbench 1 at the position of the limit frame 72. The limit frame 72 is slidably connected to the second guide rail 73 via a slider. Two guide rods 74 are symmetrically slidably connected to the surface of the limit frame 72 via a positioning cylinder. A connecting plate 76 is fixedly connected to the end of each guide rod 74 away from the limit frame 72. A spring 75 is wound around the surface of each guide rod 74, with both ends of the spring 75 connected to the limit frame 72. The frame 72 and the connecting plate 76 are fixedly connected. Several plug gauges 77 are installed along the axis on the side of the connecting plate 76 facing the third positioning turntable 711. Each plug gauge 77 is in the same position as the hole opened on the roller surface. A pressure sensor 78 is installed on the side of the limiting frame 72 facing the connecting plate 76 by bolts. A second photoelectric sensor transmitter 79 is installed on the top surface of the worktable 1. The second photoelectric sensor transmitter 79 is located on one side of the third positioning turntable 711. A second photoelectric sensor receiver 710 is set on the other side of the third positioning turntable 711 away from the second photoelectric sensor transmitter 79. The holes in each row on the roller surface correspond to each other. When it is necessary to detect the surface roughness of the roller, the roller is placed on the surface of the third positioning turntable 711. Then, the probe of the contact profilometer 5 is brought into contact with the outer wall of the roller. The roughness of the roller is detected by the lifting and lowering of the probe of the contact profilometer 5 and the rotation of the roller.

[0058] When it is necessary to check whether the opening of the hole on the roller surface is not up to standard, the roller starts to rotate after being placed on the top surface of the third positioning turntable 711 until the light emitted by the second photoelectric sensor transmitter 79 passes through the hole opened on the roller and is received by the second photoelectric sensor receiver 710. At this time, the third positioning turntable 711 stops rotating. Then the fifth electric push rod 71 is connected to the external power supply and starts. The limit frame 72 will push the connecting plate 76 towards the roller through the spring 75 until the plug gauge 77 is inserted into the corresponding hole. When it can be inserted, it proves that the opening of the hole on the roller surface is qualified. When it cannot be inserted, the connecting plate 76 will squeeze the spring 75, the guide rod 74 will slide inside the limit frame 72, and the pressure sensor 78 will be stopped by the force. At this time, it proves that the opening of the hole is not up to standard.

[0059] To solve the technical problem of classifying rollers, the present invention employs a discharge assembly 6 including a fixed frame 61 fixedly connected to the side of the worktable 1 away from the roller conveying assembly 3. The fixed frame 61 has a Y-shaped structure, and a servo motor 62 is installed on the bottom surface of the fixed frame 61. The output shaft of the servo motor 62 passes through the surface of the fixed frame 61 and is fixedly connected to a guide plate 63. The guide plate 63 is located at the intersection of the Y-shape of the fixed frame 61. After the rollers are inspected, they are placed on the surface of the fixed frame 61 by the station transfer mechanism. Because the fixed frame 61 is inclined, the rollers will slide away from the worktable 1. The swing of the guide plate 63 driven by the servo motor 62 can classify the qualified and unqualified rollers.

[0060] In a further embodiment, the discharge component 6 can be configured as two partially staggered conveyor belts, with the stagger dimension of the two conveyor belts being larger than the outer diameter of the roller. By starting the two conveyor belts separately and cooperating with the station transfer mechanism, qualified and unqualified products can be transported separately.

[0061] It should be noted that the motor used in this application is a servo motor with an encoder. The number of rotations and the rotation angle of the motor output shaft are controllable and highly accurate. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0062] It should be noted that in this application, the magnetic ring 23 is a neodymium iron boron permanent magnet, and the rollers that cooperate with the magnetic ring 23 to magnetically attract are all ferritic stainless steel, so as to achieve magnetic attraction.

[0063] The present invention is used in the following steps:

[0064] S1: When it is necessary to transport the roller, place the roller on the surface of the conveyor belt of the conveyor mechanism 31, and then start the motor inside the conveyor mechanism 31 so that the roller can move towards the worktable 1. After moving to a certain distance, the roller will block the light emitted by the first photoelectric sensor transmitter 32, so that the first photoelectric sensor receiver 33 cannot receive it. Then the motor inside the conveyor mechanism 31 will stop running, and the initial position of the roller before detection is determined.

[0065] S2: When the roller needs to be moved, the second motor 37 is connected to an external power source and started. The positioning block 36 will slide on the surface of the positioning block 36 due to the rotation of the lead screw 38 until the limiting cylinder 316 and the roller are on the same axis. Then, the third electric push rod 39 is connected to an external power source and started. The connecting frame 310 will drive the limiting cylinder 316 to move towards the roller until the extrusion block 314 is inserted into the inside of the roller. Then, the fourth electric push rod 311 is connected to an external power source and started. The connecting plate 312 will move downward inside the limiting cylinder 316. When the connecting plate 312 moves, several connecting rods will rotate on the surface of the connecting plate 312 due to the limiting groove 313. This will cause the extrusion block 314 to move closer to each other towards the inner wall of the roller until it is in contact with the roller. The roller is limited by friction. Then, by retracting the third electric push rod 39, the roller is lifted. Then, by rotating the lead screw 38, the positioning block 36 drives the roller to move, thus realizing the transfer of the roller's working position.

[0066] S3: When it is necessary to position the roller before inspection, align the roller with the placement plate 22 on the same axis, and then place the roller on the surface of the positioning cone 24. The bottom end of the roller will contact the second positioning turntable 28, and the roller will be positioned by the magnetic force of the second positioning turntable 28, thus achieving the positioning of the roller before inspection.

[0067] S:4: Before testing after roller installation, to make the edge of the roller more obvious when it rotates, the internal reduction motor of the second positioning turntable 28 is activated, so that the first bracket 29 faces the roller. Then, the first electric push rod 212 is connected to the external power supply and started. The first electric push rod 212 will push the sliding frame, which will drive the internal mold cleaning agent tank 210 to move towards the roller until one end of the first bracket 29 limits the mold cleaning agent tank 210. At this time, the nozzle of the mold cleaning agent tank 210 is directly above the edge of the roller. As the mold cleaning agent tank 210 is squeezed, the liquid inside the mold cleaning agent tank 210 is sprayed towards the edge of the roller to wash away the dirt on the edge of the roller.

[0068] S5: After cleaning is completed, start the reduction motor inside the second positioning turntable 28, so that the output end rotates 180 degrees, so that the second bracket 213 faces the drum. Then, connect the second electric push rod 214 to the external power supply and start it. The output shaft of the second electric push rod 214 will drive the connecting pipe 215 to move towards the drum through the connector. The sponge 216 will slide out from the inside of the protective shell 217 until the sponge 216 is located at the edge of the drum. Then, through the external centrifugal pump, the fluorescent agent is sprayed into the inside of the sponge 216 through the connecting pipe 215. The fluorescent agent will seep out through the sponge 216 and be applied to the edge of the drum by the rotation of the drum. The fluorescent agent makes the edge of the drum more obvious when the drum is inspected.

[0069] S6: When the roller needs to be inspected after positioning, start the reduction motor inside the first positioning turntable 21. The placement plate 22 will drive the roller to rotate. Then, connect the first motor 26 to the external power supply and start it. The first motor 26 will indirectly drive the vision sensor 27 to rotate around the positioning rod 25 as the axis until the vision sensor 27 rotates to the top of the roller and is on the same axis as the roller. This completes the adjustment of the position of the vision sensor 27. Then, the vision sensor 27 can be used to observe whether the roller is eccentric or deformed when it rotates.

[0070] S7: When the other end of the roller needs to be inspected after one end of the roller has been inspected, the clamping cylinder 44 is connected to the external air pump and started. The two clamping plates 45 will move closer to each other until they clamp the roller. Then the first cylinder 41 is connected to the external air pump and started. The first cylinder 41 will indirectly drive the clamping cylinder 44 to move upward through the fixed shell 43, thus pulling the roller out from the surface of the positioning cone 24. Then the rotating cylinder 42 is connected to the external air pump and started. The rotating cylinder 42 drives the roller to rotate 180 degrees through the clamping cylinder 44, thus realizing the rotation of the roller. Then the piston of the first cylinder 41 is retracted, so that the roller is put back on the surface of the positioning cone 24, thus realizing the repositioning of the roller.

[0071] S8: When it is necessary to detect the surface roughness of the roller, place the roller on the surface of the third positioning turntable 711, and then make the probe of the contact profilometer 5 contact the outer wall of the roller. The roughness of the roller can be detected by the lifting and lowering of the probe of the contact profilometer 5 and the rotation of the roller.

[0072] S9: When it is necessary to detect whether the opening of the hole on the surface of the roller is not up to standard, the roller starts to rotate after being placed on the top surface of the third positioning turntable 711 until the light emitted by the second photoelectric sensor transmitter 79 passes through the hole opened in the roller and is received by the second photoelectric sensor receiver 710. At this time, the third positioning turntable 711 stops rotating. Then the fifth electric push rod 71 is connected to the external power supply and starts. The limit frame 72 will push the connecting plate 76 towards the roller through the spring 75 until the plug gauge 77 is inserted into the corresponding hole. When it can be inserted, it proves that the opening of the hole on the surface of the roller is qualified. When it cannot be inserted, the connecting plate 76 will squeeze the spring 75, the guide rod 74 will slide inside the limit frame 72, and the pressure sensor 78 will be stopped by the force. At this time, it proves that the opening of the hole is not up to standard.

[0073] S10: After the roller inspection is completed, it will be placed on the surface of the fixed frame 61 by the station transfer mechanism. Because the fixed frame 61 is set at an angle, the roller will slide away from the worktable 1. The guide plate 63 can be swung by the servo motor 62 to classify the qualified and unqualified rollers.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
