[0018] Compared with the prior art, the automatic online detection device for electrochemical aluminum stamping foil has the advantages that when the electrochemical aluminum stamping foil is detected in motion, the balance of the electrochemical aluminum stamping foil in motion can be automatically adjusted at high speed, the imaging blur caused by foil fluctuation is avoided, the accuracy of foil surface flaw recognition is maintained, the flaw missed detection is avoided, and the accuracy of the detection result is improved.

[0019] The moving mechanism is arranged on the support frame and is used for adjusting the position of the balance roller shaft. The position of the balance roller shaft on the equipment support frame is adjusted according to the change in the width of the electrochemical aluminum stamping foil and the fluctuation in the transmission motion process. The running cylinder can control the movement of the positioning seat, and the transmission support rod can control the transverse movement of the moving seat, so as to adjust the transverse direction of the balance roller shaft and adjust the distance between the balance roller shaft and the industrial camera. The closer the balance roller shaft is moved to the industrial camera, the shorter the length of the electrochemical aluminum stamping foil suspended below the industrial camera, and the smaller the fluctuation range of the foil caused by the airflow and the insufficient rigidity of the foil itself. Therefore, the balance of the electrochemical aluminum stamping foil in motion can be maintained, the tension fluctuation of the foil in motion is small, and the accuracy of the surface flaw recognition of the foil can be maintained.

[0020] When the balance roller shaft is controlled to move close to the industrial camera, the lifting base moves transversely synchronously with the driving roller.

When the balance roller shaft is controlled to move and adjust, the balance roller shaft can drive the thickened flexible rope to stretch and move. The thickened flexible rope is locally limited on the surface of the electrochemical aluminum stamping foil under the pressing action of the pressing rod. The ball at the bottom of the thickened flexible rope is pressed on the surface of the electrochemical aluminum stamping foil. When the electrochemical aluminum stamping foil is detected in motion, the ball rolls in cooperation. The vibration amplitude of the foil can be limited by the multi-point limiting of the ball, the instantaneous tension deviation caused by vibration can be reduced, the limiting direction of the thickened flexible rope is perpendicular to the limiting direction of the balance roller shaft, the limiting direction of the thickened flexible rope is parallel to the edge of the electrochemical aluminum stamping foil, the problems of edge relaxation and middle wrinkles during the motion of the foil can be effectively avoided, the balance roller shaft effectively maintains the stability of the transmission motion of the electrochemical aluminum stamping foil, and the accuracy of the online detection data is improved.

[0022] According to the width size of the electrochemical aluminum stamping foil, the limiting position of the thickening flexible rope can be adjusted, the rotation of the bidirectional threaded rod is controlled, the two groups of main moving frames and vice moving frames on the balance roller shaft and the secondary upper guide roller are synchronously controlled to move, the range of the thickening flexible rope and the balance roller shaft limiting the electrochemical aluminum stamping foil is adjusted, and the interference of the transmission fluctuation of the electrochemical aluminum stamping foil on online detection is reduced.

[0038] Please refer to Figures 2-4 The guide mechanism comprises a first-stage lower guide roller 6 fixedly installed on the equipment support 1, and a first-stage upper guide roller 7 fixedly installed directly above the first-stage lower guide roller 6 on the equipment support 1; a second-stage lower guide roller 8 is fixedly installed on the equipment support 1, and a second-stage upper guide roller 9 is fixedly installed directly above the second-stage lower guide roller 8 on the equipment support 1; the electrochemical aluminum stamping foil passes between the first-stage lower guide roller 6, the first-stage upper guide roller 7, the second-stage lower guide roller 8, and the second-stage upper guide roller 9; the height of the second-stage lower guide roller 8 and the second-stage upper guide roller 9 is higher than the height of the first-stage lower guide roller 6 and the first-stage upper guide roller 7.

[0039] Please refer toFigures 4-8 The moving mechanism comprises a moving seat 11 horizontally slidingly installed on the equipment support 1, a supporting seat 12 fixedly installed on the moving seat 11, and a lifting base 13 longitudinally slidingly installed on the supporting seat 12. The balancing roller shaft 10 is fixedly connected between the two lifting bases 13. The equipment support 1 is fixedly installed with a cylinder 111, the output end of the cylinder 111 is fixedly connected with a positioning seat 112, the positioning seat 112 is rotationally connected with a transmission support 113, and the other end of the transmission support 113 is rotationally connected with the moving seat 11. The supporting seat 12 is longitudinally slidingly connected with a guide support 131, the guide support 131 is fixedly connected with the lifting base 13, and the guide support 131 is elastically connected with the supporting seat 12 through a positioning spring 132. The lifting base 13 is fixedly connected with a driving roller 133 below the balancing roller shaft 10. The equipment support 1 is fixedly connected with a supporting frame 134 between the two balancing roller shafts 10, and the supporting frame 134 is obliquely connected with a guide frame 135 on both sides. The driving roller 133 is slidingly connected in the guide frame 135.

[0040] The electrochemical aluminum stamping foil is wound on the outside of the feeding roller shaft 4, guided by the first lower guide roller 6, the first upper guide roller 7, the second lower guide roller 8 and the second upper guide roller 9, and wound on the outside of the winding roller shaft 5. A motor is arranged beside the equipment support 1 and connected with the feeding roller shaft 4 and the winding roller shaft 5 to control the rotation of the two to drive the electrochemical aluminum stamping foil to move in the equipment support 1. The multispectral light source group 3 emits light to the surface of the electrochemical aluminum stamping foil, and the industrial camera 2 collects high-definition images of the foil surface to detect defects on the surface of the electrochemical aluminum stamping foil in real time.

[0041] The balance roller shaft 10 is pressed on the surface of the anodized aluminum stamping foil. Before detection, the position of the balance roller shaft 10 is adjusted according to the fluctuation of the image collected by the anodized aluminum stamping foil, so as to keep the anodized aluminum stamping foil balanced. The running cylinder 111 controls the movement of the positioning seat 112. The transmission support rod 113 connected between the positioning seat 112 and the moving seat 11 rotates correspondingly. The rotating transmission support rod 113 can push the moving seat 11 to move laterally on the equipment support 1. The moving seat 11 drives the lifting base 13 and the balance roller shaft 10 to move laterally, so as to adjust the distance between the balance roller shaft 10 and the industrial camera 2, thereby adjusting the length of the anodized aluminum stamping foil hanging below the industrial camera 2, keeping the transmission of the anodized aluminum stamping foil balanced. While controlling the lateral movement of the balance roller shaft 10, the driving roller 133 on the lifting base 13 moves synchronously. The driving roller 133 moves directionally in the guide frame 135. Since the guide frame 135 is inclinedly connected beside the support frame 134, the driving roller 133 moves obliquely in the guide frame 135, which generates longitudinal displacement. The driving roller 133 drives the lifting base 13 and the balance roller shaft 10 to move downward synchronously. The guide support 131 at the bottom of the lifting base 13 moves downward in the supporting seat 12 and compresses the adjusting positioning spring 132. When the balance roller shaft 10 moves downward, it is pressed on the surface of the anodized aluminum stamping foil, which can further adjust the tension of the anodized aluminum stamping foil transmission, reduce the tension fluctuation of the anodized aluminum stamping foil transmission, and enable the industrial camera 2 to collect clear foil surface images and accurately identify the defects on the foil surface during online detection, thereby improving the detection data accuracy.

[0042] If the foil surface at the discharge roller shaft 4 and the winding roller shaft 5 is inclined, it is easy to wrinkle when stretched to the first-level upper guide roller 7, the first-level lower guide roller 6, the second-level upper guide roller 9 and the second-level lower guide roller 8. During online detection, the balance roller shaft 10 can be moved to press and limit the both sides of the foil detection area, adjust the foil wrinkle part in the middle part, keep the flatness of the foil in the detection area, and prevent the detection from being disturbed by the transmission inclination of the foil.

[0043] Embodiment two: please refer to Figures 8-12 On the basis of embodiment one, a stabilizing mechanism is further disclosed, and the specific structure is as follows: a stabilizing mechanism for further keeping the workpiece transmission balanced is arranged between the balance roller shaft 10 and the second-level upper guide roller 9. The stabilizing mechanism comprises a main moving frame 14 clamped and slidably installed on the balance roller shaft 10, and a secondary moving frame 15 clamped and slidably installed on the second-level upper guide roller 9. A thickened flexible rope 16 is fixedly connected to the main moving frame 14 along the axis direction, and the thickened flexible rope 16 is slidably connected to the secondary moving frame 15. A plurality of balls 17 are rotatably embedded at equal intervals at the bottom of the thickened flexible rope 16, and the balls 17 press the surface of the workpiece.

[0044] Please refer to Figures 8-12The slide bar 18 is symmetrically and slidably connected to the auxiliary moving frame 15 relative to the thickened flexible rope 16, and a fixed sheet 19 is fixedly installed on the slide bar 18 away from the main moving frame 14, and the fixed sheet 19 is fixedly connected to the other end of the thickened flexible rope 16. The reset spring 20 is elastically connected between the fixed sheet 19 and the auxiliary moving frame 15, and the reset spring 20 is externally sleeved on the slide bar 18. The rotating frame 21 is rotatably installed on the main moving frame 14 and the auxiliary moving frame 15, the pressing rod 22 for pressing and limiting the thickened flexible rope 16 is installed on the rotating frame 21, and the clamping groove 23 for clamping and connecting the thickened flexible rope 16 is formed in the pressing rod 22. The bidirectional threaded rod 24 is rotatably connected inside the secondary upper guide roller 9 and the balance roller shaft 10 along the axial direction, and the two groups of auxiliary moving frames 15 and main moving frames 14 on the secondary upper guide roller 9 and the balance roller shaft 10 are threadedly sleeved on the two sides of the threaded outer portion of the bidirectional threaded rod 24.

[0045] When the distance between the balance roller shaft 10 and the industrial camera 2 is adjusted, the balance roller shaft 10 drives the main moving frame 14 to move synchronously, the main moving frame 14 stretches the thickened flexible rope 16 when moving horizontally, so that the thickened flexible rope 16 moves through the auxiliary moving frame 15, and the fixed sheet 19 is driven to move synchronously by the thickened flexible rope 16, the slide bar 18 is driven to slide through the auxiliary moving frame 15 by the fixed sheet 19, and the reset spring 20 is compressed. This part of the structure cooperates with the movement adjustment of the thickened flexible rope 16, then the micro motor on the main moving frame 14 and the auxiliary moving frame 15 is operated to control the rotating frame 21 to rotate, the rotating frame 21 drives the pressing rod 22 to rotate downward, so that the clamping groove 23 on the pressing rod 22 is clamped on the surface of the thickened flexible rope 16, the thickened flexible rope 16 is locally limited on the upper end surface of the anodized aluminum stamping foil, and according to the change of the balance roller shaft 10 in the horizontal and vertical positions, the thickened flexible rope 16 can be adjusted in cooperation with the balance roller shaft 10, for example, when the balance roller shaft 10 presses the anodized aluminum stamping foil, so that the anodized aluminum stamping foil has a downward inclined state locally, the thickened flexible rope 16 can be inclined and limited on the upper end surface of the anodized aluminum stamping foil, and always maintains the state of being limited on the foil surface, the ball 17 below the thickened flexible rope 16 is pressed and combined on the surface of the anodized aluminum stamping foil, when the anodized aluminum stamping foil is transmitted and moved, the ball 17 is driven to roll in a certain direction, under the limitation of multiple points of the ball 17, the long-distance suspension and unlimited state between the secondary upper guide roller 9 and the balance roller shaft 10 is avoided, the vibration amplitude of the foil surface is limited, the instantaneous tension deviation caused by vibration is reduced, the limiting direction of the thickened flexible rope 16 is perpendicular to the limiting direction of the balance roller shaft 10, the limiting direction is parallel to the edge of the anodized aluminum stamping foil, which can effectively avoid the problems of edge relaxation and middle wrinkle of the foil surface when the foil surface moves, further maintains the balance state of the anodized aluminum stamping foil during movement detection, and reduces the interference of tension fluctuation.

[0046] According to the width of the electrochemical aluminum stamping foil, the distance between the two groups of thickened flexible ropes 16 can be adjusted. The micro motor outside the balance roller shaft 10 and the secondary upper guide roller 9 controls the rotation of the bidirectional threaded rod 24. The bidirectional threaded rod 24 is screw-connected with the main moving frame 14 and the auxiliary moving frame 15. Under the screw transmission, the relative movement of the two groups of main moving frames 14 on the balance roller shaft 10 can be controlled, and the relative movement of the two groups of auxiliary moving frames 15 on the secondary upper guide roller 9 can also be controlled. The consistency of the moving adjustment positions of the main moving frame 14 and the auxiliary moving frame 15 is maintained, so that the thickened flexible rope 16 is located near the edge of the electrochemical aluminum stamping foil, effectively limiting the situation of the foil edge relaxation.
