[0001] The present invention relates to the technical field of mirror roller detection, and particularly relates to a surface defect detection device and a detection method for a mirror roller. Background Art

[0002] A mirror roller is a roller whose surface has been precisely processed to achieve a mirror effect, and is mainly used in processes such as calendering, coating, and compounding of materials such as plastics, rubbers, papers, and metals. Its high surface finish ensures that the product surface is flat and smooth, and its quality and performance directly determine the quality of the processed product.

[0003] Traditional mirror roller detection usually adopts the methods of manual sampling inspection and mechanical detection. Manual sampling inspection is simple and low-cost, while the mechanical detection method can improve the detection speed and accuracy. However, manual detection is not only time-consuming and laborious, but also has a limited sampling frequency, making it difficult to comprehensively cover all products. Moreover, during the manual detection process, factors such as the experience, skill level, and fatigue degree of the detection personnel may affect the accuracy and consistency of the detection results. Most of the existing detection devices can only complete a single detection task and lack integrated processing functions such as automatic acquisition, automatic rotation, automatic detection, and automatic classification.

As the mirror roller is conveyed, the rotating frame deflects by a certain angle, and in cooperation with the arc - shaped guide bar, the movable guide plate rotates clockwise. Finally, the mirror roller in the shifting ring is introduced between the fixed guide rail and the rotating frame. The friction part on the inner wall of the fixed guide rail enables the mirror roller to rotate self - sufficiently during movement. In cooperation with the laser detection equipment, it can automatically detect defects, automatically grab the mirror roller to be detected, and send it to the detection station, with high automation and simple operation.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] Refer to the attached Figure 1-8 A mirror roller surface defect detection device includes a conveying platform 1 for conveying workpieces, a support frame 11 and a control box 12 are provided on the conveying platform 1, a control module is provided in the support frame 11, and the control module is used to set the frequency of random inspection, and also includes: Detection component 2, the detection component 2 includes a fixed guide rail 21 and a rotating frame 22. The diameter of the fixed guide rail 21 is larger than that of the rotating frame 22. The fixed guide rail 21 is fixedly arranged on the support frame 11. An opening is provided on one side of the fixed guide rail 21 close to the conveying table 1, and both ends of the fixed guide rail 21 are higher than the workpieces transported on the conveying table 1 to prevent affecting the normal conveyance of the workpieces during normal conveyance and when detection is not required. The rotating frame 22 is rotatably arranged on the support frame 11 and is located inside the fixed guide rail 21. There is a gap between the rotating frame 22 and the fixed guide rail 21, so that the mirror roller can move between the fixed guide rail 21 and the rotating frame 22. An active guide plate 211 for guiding the workpiece into the fixed guide rail 21 is provided on the fixed guide rail 21. In the initial state, the end of the active guide plate 211 away from the fixed guide rail 21 is higher than the workpiece. The active guide plate 211 is located on the side of the fixed guide rail 21 close to the support frame 11, and an adjusting gear 212 is coaxially installed on the active guide plate 211. A first rack 213 meshing with the adjusting gear 212 is movably installed on the fixed guide rail 21. A guiding frame 214 is provided on the fixed guide rail 21, and the first rack 213 is slidably connected to the guiding frame 214 and extends towards the arc-shaped guide bar 221. A limiting block 2131 is provided on the first rack 213, and the limiting block 2131 is used to limit the excessive flipping of the active guide plate 211. When detection is required, the active guide plate 211 flips clockwise and rotates the end away from the fixed guide rail 21 to a position lower than the workpiece, and then follows the movement of the workpiece and is guided into the space between the fixed guide rail 21 and the rotating frame 22. An arc-shaped guide bar 221 for guiding the flipping of the active guide plate 211 is provided on the rotating frame 22. When the arc-shaped guide bar 221 rotates following the rotating frame 22, it will push the first rack 213 to move on the guiding frame 214, and then drive the adjusting gear 212 to drive the active guide plate 211 to rotate clockwise to achieve the guiding of the workpiece. A slip ring 222 is provided on the rotating frame 22. A ring-shaped groove is provided on the slip ring 222, and a conductive needle extending into the ring-shaped groove and communicatively connected to the control box 12 is provided on the support frame 11. Through the cooperation of the control box 12 and the slip ring 222, the slip ring 222 is powered on when the mirror roller needs to be detected; The dial ring 23 is provided with an open groove for receiving the workpiece, and a yield groove 2301 is provided at the bottom of the dial ring 23. A movable arc ring 231 is rotatably installed on the dial ring 23, and a counterweight block 232 located in the yield groove 2301 is provided at the bottom of the movable arc ring 231. When the dial ring 23 is not deflected, the workpiece enters the dial ring 23 from the open groove, and then the dial ring 23 is squeezed by the workpiece to deflect at a moving angle, thereby driving the arc guide bar 221 to drive the movable guide plate 211 to rotate clockwise to guide the workpiece into the fixed guide rail 21. After that, the rotating frame 22 is actively driven and rotated. At this time, the dial ring 23 is tilted, and the counterweight block 232 is always facing the ground due to gravity, thereby driving the movable arc ring 231 to rotate on the dial ring 23 and closing the dial ring. The open groove on the ring 23 prevents the mirror roller from falling during the detection process. An iron ring 24 is provided on the side of the dial ring 23 close to the rotating frame 22. An elastic member 26 electrically connected to the conductive ring 222 is provided on the rotating frame 22, and an electromagnetic ring 25 is provided between the iron ring 24 and the elastic member 26. A laser detection device 27 is provided on the side of the rotating frame 22 close to the dial ring 23. The inner ring arm of the fixed guide rail 21 is provided with a friction-increasing material for increasing friction, such as silicone, rubber, etc., and the inner ring arm of the dial ring 23 is provided with a ball. Since the electromagnetic ring 25 is energized to generate magnetism, it always attracts the iron ring 24 to make the dial ring 23 press the mirror roller against the fixed guide rail 21. The mirror roller cooperates with the friction member on the inner wall of the fixed guide rail 21 to make the mirror roller rotate during movement. The ball is used to reduce the friction between the mirror roller and the dial ring 23, and then cooperates with the laser detection device 27 to detect defects on the surface of the mirror roller.

[0021] In the above technical scheme, a detection signal is sent through the control box 12, and the electromagnetic ring 25 is energized through the conductive ring 222 to adsorb the iron ring 24, drive the dial ring 23 to descend and obtain the mirror roller, and with the transportation of the mirror roller, the rotating frame 22 is deflected at a certain angle, and the movable guide plate 211 is rotated clockwise in cooperation with the arc guide bar 221, and finally the mirror roller in the dial ring 23 is introduced between the fixed guide rail 21 and the rotating frame 22, and the friction parts on the inner wall of the fixed guide rail 21 are used to make the mirror roller rotate during the movement, and the laser detection equipment 27 is used to automatically perform defect detection, and it can automatically grab the mirror roller to be detected and send it to the detection station, with a high degree of automation and simple operation.

[0022] Furthermore, a movable guide rail 1 215 and a movable guide rail 2 216 located below the movable guide rail 1 215 are rotatably installed on the lead-out end of the fixed guide rail 21 away from the support frame 11. The movable guide rail 2 216 is rotatably set on the conveying platform 1 through a bracket, and a toggle gear 1 2151 is provided on the rotating shaft of the movable guide rail 1 215, and a toggle gear 2 2161 is provided on the rotating shaft of the movable guide rail 2 216, and the toggle gear 1 2151 and the toggle gear 2 2161 are connected by a transmission member.

[0023] In addition, the transmission member includes a driving plate 217 slidably set on the support frame 11, and a driving device for driving the driving plate 217 to rise and fall is set in the support frame 11, and two sets of racks are provided on the driving plate 217, and the two sets of racks are respectively located on the opposite sides of the toggle gear 1 2151 and the toggle gear 2 2161, that is, when the driving plate 217 moves up and down, the movable guide rail 1 215 and the movable guide rail 2 216 are driven to rotate in opposite directions, and the control box 12 judges the result signal after the detection and drives the driving plate 217 to rise and fall, and guides the qualified mirror rollers and the unqualified mirror rollers to different areas for collection.

[0024] In the above technical solution, after detection by the laser detection device 27, the detection result is transmitted to the control box 12, and the control box 12 determines and drives the lifting and lowering of the driving plate 217, and guides the qualified and unqualified mirror rollers to different places for collection, without manual intervention.

[0025] A method for detecting surface defects of a mirror roller is applied to the above-mentioned device for detecting surface defects of a mirror roller. The steps of the detection method are as follows: S1, the mirror roller is transported through the conveyor 1. When inspection is required, the control box 12 generates a signal to energize the conductive ring 222, and then the electromagnetic ring 25 is energized to generate magnetic attraction to the iron ring 24 to drive the dial ring 23 to descend; S2, the shifting ring 23 descends and as the workpiece is transported, the mirror roller enters the shifting ring 23 and shifts the rotating frame 22 to rotate. At this time, the arc-shaped guide bar 221 guides the movable guide plate 211 to rotate clockwise and guide the mirror roller into the fixed guide rail 21; S3, the rotating frame 22 actively rotates and drives the mirror roller to move along the axis of the rotating frame 22, and at the same time, the ring 23 pushes the mirror roller against the fixed guide rail 21, and the friction material on the inner wall of the fixed guide rail 21 makes the mirror roller rotate, and then cooperates with the laser detection equipment 27 to detect surface defects; S4, the laser detection device 27 sends the detection result to the control box 12, and the control box 12 controls the driving plate 217 to move up and down, adjusts the docking relationship between the movable guide rail 1 215 and the movable guide rail 216 and the fixed guide rail 21, and then transports the qualified and unqualified products separately.
