When the aluminum foil is pulled to one end of the recovery cylinder 4, the end of the aluminum foil is fixed on the recovery cylinder 4, and the recovery motor 40 on the recovery cylinder 4 is used to continuously pull the aluminum foil on the release cylinder 2 through the detection box 10 for detection and marking.

[0033] Specifically, after the aluminum foil is installed between the release cylinder 2 and the recovery cylinder 4, in order to ensure the tension of the aluminum foil, a clamping mechanism 3 is set at the edge of the detection box 10 to clamp the two ends of the aluminum foil. During clamping, the telescopic cylinder 1 38 is controlled to move, so that the tension pulley 37 moves in the horizontal guide rail 36, thereby pulling the driving belt 35, and then the pulleys 34 at the ends of the clamping roller 1 31 and the clamping roller 2 32 are close to each other, and then the clamping roller 1 31 and the clamping roller 2 32 are close to each other, so as to achieve the clamping operation of the aluminum foil.

[0034] Further, such as Figure 3 As shown, the transmission mechanism 5 includes a rack 50 arranged on the bottom edge of the detection box 10, and clamping guide rails 51 are arranged on both sides of the rack 50. A clamping frame 52 is arranged on the clamping guide rails 51, and a matching gear 53 is rotatably installed in the clamping frame 52. The matching gear 53 and the rack 50 are meshed with each other. The matching gear 53 is connected to a travel motor 54, and a rotating motor 56 is arranged on the clamping frame 52. The rotating motor 56 is connected to a rotating frame 55, and the rotating frame 55 is connected to a right-angle frame 57. The rotating frame 55 and the right-angle frame 57 are movably installed through a plug-in column 58. A telescopic motor 59 is arranged between the rotating frame 55 and the right-angle frame 57, and the right-angle frame 57 is fixedly installed to the end of the aluminum foil.

[0035] Specifically, the travel motor 54 drives the right angle frame 57 to move to one end of the detection box 10 close to the release cylinder 2, and the rotating motor 56 drives the rotating frame 55 and the right angle frame 57 to rotate to a vertical state, and the edge of the aluminum foil is fixed on a right angle side of the right angle frame 57, and then the travel motor 54 drives the aluminum foil to cross the detection box 10 until it is close to the end of the recycling cylinder 4, and the aluminum foil is fixed on the recycling cylinder 4. The aluminum foil on the release cylinder 2 is continuously pulled into the detection box 10 for detection by the recycling motor 40. After the aluminum foil reaches the recycling cylinder 4, the rotating motor 56 controls the rotating frame 55 and the right angle frame 57 to rotate to a horizontal state to avoid interference with the movement of the aluminum foil and the subsequent detection marking mechanism 7.

[0036] Further, such as Figure 3 As shown, positioning columns 511 are symmetrically arranged on the right-angle frame 57, a pressure plate 510 is arranged on the right-angle frame 57, both ends of the pressure plate 510 are plugged into the positioning columns 511, penetrating columns 512 are evenly arranged on the pressure plate 510, the penetrating columns 512 and the right-angle frame 57 are plugged into each other, and a telescopic cylinder 513 is arranged between the right-angle frame 57 and the pressure plate 510.

[0037] Specifically, the movement of the pressing plate 510 is controlled by the telescopic cylinder 513. When the aluminum foil moves between the pressing plate 510 and the right-angle frame 57, the telescopic cylinder 513 is used to control the pressing plate 510 and the right-angle frame 57 to approach each other, so that the penetrating column 512 pierces the aluminum foil, thereby fixing the end of the aluminum foil and ensuring that the aluminum foil is reliably carried to one end of the paper recovery tube 4.

[0038] Further, such as Figure 4 As shown, the positioning mechanism 6 includes a storage tube 60 arranged on the outside of the detection box 10, a center column 61 is arranged in the storage tube 60, an outer circle of the center column 61 is evenly provided with opening plates 62, an opening control component 63 is arranged between the opening plate 62 and the center column 61, and a push-pull component 64 is arranged between the detection box 10 and the center column 61.

[0039] Specifically, after the aluminum foil passes through the detection box 10 under the carrying of the transmission mechanism 5, the central column 61 and the opening plate 62 in the storage tube 60 are driven by the push-pull component 64 to enter the interior of the detection box 10. At this time, the aluminum foil is located above the central column 61 and the opening plate 62. The opening control component 63 controls the opening plate 62 to open outward, thereby lifting the aluminum foil and making the aluminum foil bulge upward. Subsequently, the aluminum foil is bent in combination with the detection marking mechanism 7 installed on both sides to realize double-sided detection, thereby improving the detection efficiency and detection integrity.

[0040] Further, such as Figure 5 , Figure 6As shown, the opening control component 63 includes a motor 630 arranged inside the central column 61, the output shaft of the motor 630 is coaxially installed with the central column 61, the output shaft of the motor 630 is connected with a rotating ring 631, the outer ring of the rotating ring 631 is evenly provided with mounting flanges 632, and a push-pull column 633 is rotatably installed on the mounting flange 632, the end of the central column 61 is circumferentially provided with a mounting groove 634 corresponding to the opening plate 62, the opening plate 62 is provided with a plug-in plate 635, the opening plate 62 is plugged between the plug-in plate 635 and the mounting groove 634, and the push-pull column 633 is rotatably installed between the end of the plug-in plate 635.

[0041] Specifically, the motor 630 controls the rotating circle 631 to rotate, and the mounting flange 632 on the edge of the rotating circle 631 drives the push-pull column 633 to move, thereby driving the plug-in board 635 to move back and forth in the mounting groove 634, thereby realizing rapid and synchronous control of the opening or retraction of the opening plate 62.

[0042] Further, such as Figure 7 As shown, the push-pull assembly 64 includes a mounting plate 640 arranged on the inner side of the detection box 10, and a fixed frame 642 is arranged on the mounting plate 640. A matching gear 643 is rotatably installed in the fixed frame 642, and the matching gear 643 is connected to a motor 644. A rack 641 is arranged on the side of the center column 61, and the matching gear 643 and the rack 641 are meshed with each other. A connecting rod 646 is also arranged on the mounting plate 640, and the connecting rod 646 is connected to a lifting ring 645, and the lifting ring 645 is sleeved on the outer side of the center column 61.

[0043] Specifically, motor 2 644 is utilized to drive matching gear 2 643 and rack 2 641 to mesh with each other, thereby driving the center column 61 to move into the detection box 10, and then carrying the opening plate 62 into the interior of the detection box 10. In order to ensure the stability of the center column 61 after entering the detection box 10, a lifting ring 645 is fixedly installed on the mounting plate 640, and the center column 61 is positioned and lifted in combination with the lifting ring 645, thereby ensuring the stability of the center column 61 before and after movement.

[0044] A detection method for a defect detection device for aluminum foil processing and production as described above, comprising the following steps: S1, installing an aluminum foil roll on a release cylinder 2, pulling out the edge of the aluminum foil, controlling the transmission mechanism 5 to approach the release cylinder 2, so that the edge of the aluminum foil is fixed between the right-angle frame 57 and the pressure plate 510, and driving the end of the aluminum foil to move to the recovery cylinder 4 in combination with the travel motor 54, and fixing it on the recovery cylinder 4; S2, controlling the push-pull component 64 in the positioning mechanism 6 to move, driving the central column 61 and the opening plate 62 to move into the detection box 10, and driving the opening plate 62 to open in combination with the opening control component 63, so that the aluminum foil is arched upward; S3, controlling the folding frame 71 to approach the aluminum foil from both sides of the positioning mechanism 6 through the lifting cylinder 70, so that the detection windows 72 of the two groups of folding frames 71 are respectively close to the two sides of the aluminum foil, and detecting and marking the defective parts on both sides of the aluminum foil in combination with the detection camera 75 and the marking pen 773.

[0045] The working principle of the embodiment of the present invention is: like Figure 1-Figure 9As shown, before the aluminum foil is inspected, the end of the aluminum foil is first fixed by the transmission mechanism 5, and the transmission mechanism 5 carries the aluminum foil through the interior of the inspection box 10, which is convenient for the subsequent defect detection on both sides of the aluminum foil. When the aluminum foil is pulled to one end of the recovery tube 4, the end of the aluminum foil is fixed on the recovery tube 4, and the recovery motor 40 on the recovery tube 4 is used to continuously pull the aluminum foil on the release tube 2 through the inspection box 10 for inspection and marking. Under the limiting action of the positioning mechanism 6, the aluminum foil is bent by the folding wire racks 71 on both sides, and the surface of the aluminum foil is visually inspected by the inspection cameras 75 on the folding wire racks 71 on both sides. When defects are found on the surface of the aluminum foil, the surface of the aluminum foil is marked by the marking assembly 77 carried by the three-axis moving table 76. The marking pen 773 on the fixed flange 772 is controlled by the electric telescopic rod 771 to perform telescopic movement, so as to facilitate the marking of the aluminum foil in the corner of the inspection window 72 and improve the marking range. After the aluminum foil is installed between the release cylinder 2 and the recovery cylinder 4, in order to ensure the tension of the aluminum foil, a clamping mechanism 3 is set at the edge of the detection box 10 to clamp the two ends of the aluminum foil. During clamping, the telescopic cylinder 1 38 is controlled to move, so that the tension pulley 37 moves in the horizontal guide rail 36, thereby pulling the driving belt 35, and then the pulleys 34 at the ends of the clamping roller 1 31 and the clamping roller 2 32 are close to each other, and then the clamping roller 1 31 and the clamping roller 2 32 are close to each other, so as to achieve the clamping operation of the aluminum foil. The right angle frame 57 is driven by the travel motor 54 to move to the end of the detection box 10 close to the release cylinder 2, and the rotating frame 55 and the right angle frame 57 are driven to rotate to a vertical state by the rotating motor 56, and the edge of the aluminum foil is fixed on a right angle side of the right angle frame 57. Then, the aluminum foil is driven to cross the detection box 10 close to the end of the recovery cylinder 4 by the travel motor 54, and the aluminum foil is fixed on the recovery cylinder 4. The aluminum foil on the release cylinder 2 is continuously pulled into the detection box 10 for detection by the recovery motor 40. After the aluminum foil reaches the recovery cylinder 4, the rotating frame 55 and the right angle frame 57 are controlled by the rotating motor 56 to rotate to a horizontal state to avoid interference with the movement of the aluminum foil and the subsequent detection marking mechanism 7. The movement of the pressing plate 510 is controlled by the telescopic cylinder 513. When the aluminum foil moves between the pressing plate 510 and the right-angle frame 57, the pressing plate 510 and the right-angle frame 57 are controlled by the telescopic cylinder 513 to approach each other, so that the penetrating column 512 pierces the aluminum foil, thereby fixing the end of the aluminum foil and ensuring that the aluminum foil is reliably carried to one end of the paper recovery tube 4.After the aluminum foil passes through the detection box 10 under the carrying of the transmission mechanism 5, the central column 61 and the opening plate 62 in the storage tube 60 are driven by the push-pull component 64 to enter the interior of the detection box 10. At this time, the aluminum foil is located above the central column 61 and the opening plate 62. The opening control component 63 controls the opening plate 62 to open outward, thereby lifting the aluminum foil and making the aluminum foil bulge upward. Then, the aluminum foil is bent in combination with the detection marking mechanism 7 installed on both sides to realize double-sided detection, thereby improving the detection efficiency and detection integrity.
