[0031] Specifically, before inspecting the aluminum foil, the ends of the foil are first secured by the transfer mechanism 5. The transfer mechanism 5 then carries the foil through the interior of the inspection box 10, facilitating subsequent defect inspection on both sides of the foil. Once the foil reaches one end of the recovery drum 4, the ends are secured to the drum. The recovery motor 40 on the drum 4 continuously pulls the foil from the release drum 2 through the inspection box 10 for inspection and marking.

[0032] Further, such as Figure 8 、 Figure 9 As shown, the detection marking mechanism 7 includes a folding frame 71 arranged on the upper and lower sides of the detection box 10, and a lifting cylinder 70 is provided on the folding frame 71. The folding frames 71 located on the upper and lower sides of the detection box 10 are centrally symmetrical with the positioning mechanism 6 as the center. Guide rollers 73 are provided at both ends of the folding frame 71. A detection window 72 is provided on the folding frame 71, and a camera frame 74 is provided at the edge of the detection window 72. A detection camera 75 is provided on the camera frame 74, and a detection window 72 is installed in the detection window 72. A three-axis movable platform 76 is provided with a marking assembly 77, and the marking assembly 77 includes a fixed plate 774 connected to the three-axis movable platform 76, and a rotation motor 775 is provided on the fixed plate 774, and a connecting plate 770 is provided on the output shaft of the rotation motor 775, and an electric telescopic rod 771 is provided on the connecting plate 770, and a fixed flange 772 is provided on the output shaft of the electric telescopic rod 771, and a marking pen 773 is provided on the fixed flange 772.

[0033] Specifically, the aluminum foil is bent by folding frames 71 on either side of the positioning mechanism 6. Inspection cameras 75 on each folding frame 71 then perform visual inspection of the foil's surface. If defects are detected, a marking assembly 77 carrying a three-axis mobile stage 76 is used to mark the foil's surface. A marking pen 773 on a fixed flange 772 is controlled by an electric telescopic rod 771 to extend and retract, facilitating marking of the foil in the corners of the inspection window 72 and extending the marking range.

[0034] Further, such as Figure 2As shown, the clamping mechanism 3 includes a side frame 30 symmetrically arranged on the side of the detection box 10, and a clamping roller 31 and a clamping roller 32 are movably installed between the side frames 30, and a vertical groove is provided on the side frame 30, and the ends of the clamping roller 31 and the clamping roller 32 are provided with a mounting slider 33, which is slidably installed between the mounting slider 33 and the vertical groove, and the ends of the clamping roller 31 and the clamping roller 32 are provided with a pulley 34, and the edge of the side frame 30 is provided with a horizontal guide rail 36, and a tensioning pulley 37 is slidably installed in the horizontal guide rail 36, and a driving belt 35 is provided between the tensioning pulley 37 and the pulley 34, and a telescopic cylinder 38 is provided at the end of the horizontal guide rail 36, and the telescopic cylinder 38 is connected to the tensioning pulley 37, and a support spring 39 is provided between the pulley 34 of the clamping roller 31 and the clamping roller 32.

[0035] Specifically, after the aluminum foil is installed between the release drum 2 and the recovery drum 4, a clamping mechanism 3 is installed on the edge of the inspection box 10 to ensure the tension of the aluminum foil. During clamping, the movement of the telescopic cylinder 1 38 is controlled to move the tension pulley 37 within the horizontal guide rail 36, thereby pulling the drive belt 35, which in turn brings the pulleys 34 at the ends of the clamping roller 1 31 and the clamping roller 2 32 closer together, thus closing the clamping roller 1 31 and the clamping roller 2 together, thus clamping the aluminum foil.

[0036] 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 a clamping guide rail 51 is provided on both sides of the rack 50. A clamping frame 52 is provided on the clamping guide rail 51, and a matching gear 53 is rotatably installed in the clamping frame 52. The matching gear 53 and the rack 50 are engaged with each other, and the matching gear 53 is connected to a walking motor 54. A rotating motor 56 is provided on the clamping frame 52, and the rotating motor 56 is connected to a rotating frame 55. 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 provided 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.

[0037] Specifically, the travel motor 54 drives the right-angle frame 57 to move to the end of the inspection box 10 near the release cylinder 2. The rotating motor 56 drives the rotating frame 55 and the right-angle frame 57 to rotate to a vertical position, and the edge of the aluminum foil is fixed to a right-angled side of the right-angle frame 57. Then, the travel motor 54 drives the aluminum foil across the inspection box 10 to the end near the recovery cylinder 4, and the aluminum foil is fixed to the recovery cylinder 4. The recovery motor 40 continuously pulls the aluminum foil on the release cylinder 2 into the inspection box 10 for inspection. After the aluminum foil reaches the recovery cylinder 4, the rotating motor 56 controls the rotating frame 55 and the right-angle frame 57 to rotate to a horizontal position to avoid interfering with the movement of the aluminum foil and the subsequent detection and marking mechanism 7.

[0038] Further, such as Figure 3 As shown, positioning columns 511 are symmetrically arranged on the right-angle frame 57, and a pressure plate 510 is provided on the right-angle frame 57. The two 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. A telescopic cylinder 2 513 is provided between the right-angle frame 57 and the pressure plate 510.

[0039] Specifically, the movement of the pressing plate 510 is controlled by the telescopic cylinder 2 513. When the aluminum foil moves between the pressing plate 510 and the right-angle frame 57, the telescopic cylinder 2 513 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.

[0040] 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.

[0041] Specifically, after the aluminum foil passes through the detection box 10 under the carrying of the transmission mechanism 5, the center 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 center 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.

[0042] Further, such as Figure 5 、 Figure 6As shown, the opening control component 63 includes a motor 630 arranged inside the central column 61, and the output shaft of the motor 630 is coaxially installed with the central column 61. The output shaft of the motor 630 is connected to a rotating ring 631, and the outer ring of the rotating ring 631 is evenly provided with mounting flanges 632. 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, and a plug-in plate 635 is provided on the opening plate 62. The opening plate 62 is plugged in 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.

[0043] Specifically, the motor 630 controls the rotating ring 631 to rotate, and the mounting flange 632 on the edge of the rotating ring 631 drives the push-pull column 633 to move, thereby driving the plug-in plate 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.

[0044] 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 provided on the mounting plate 640. A matching gear 2 643 is rotatably installed in the fixed frame 642, and the matching gear 2 643 is connected to a motor 2 644. A rack 2 641 is provided on the side of the center column 61, and the matching gear 2 643 and the rack 2 641 are engaged with each other. A connecting rod 646 is also provided 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.

[0045] Specifically, motor 2 644 is used to drive the matching gear 2 643 and rack 2 641 to engage with each other, 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 to ensure the stability of the center column 61 before and after movement.

[0046] A detection method for a defect detection device for aluminum foil processing and production as described above includes the following steps: S1, installing an aluminum foil roll on a release drum 2, pulling out the edge of the aluminum foil, controlling the transmission mechanism 5 to approach the release drum 2, so that the edge of the aluminum foil is fixed between the right-angle frame 57 and the pressure plate 510, and combining with the travel motor 54 to drive the end of the aluminum foil to move to the recovery drum 4 and fix it on the recovery drum 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 combining with the opening control component 63 to drive the opening plate 62 to open, so that the aluminum foil arches upward; S3, controlling the folding frame 71 through the lifting cylinder 70 to approach the aluminum foil from both sides of the positioning mechanism 6, 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 combining with the detection camera 75 and the marking pen 773 to detect and mark the defective parts on both sides of the aluminum foil.

[0047] The working principle of the embodiment of the present invention is:

[0048] like Figures 1-9As shown, before inspecting the aluminum foil, the ends of the foil are first secured by a transfer mechanism 5. The transfer mechanism 5 then carries the foil through the interior of the inspection box 10, facilitating subsequent defect detection on both sides of the foil. When the foil is pulled to one end of the recovery drum 4, the ends are secured to the recovery drum 4. The recovery motor 40 on the recovery drum 4 continuously pulls the foil on the release drum 2 through the inspection box 10 for inspection and marking. Under the limiting action of the positioning mechanism 6, the foil is bent by the folding wire frames 71 on both sides. The inspection cameras 75 on the folding wire frames 71 on both sides perform visual inspection of the surface of the foil. If defects are found on the surface of the foil, the marking assembly 77 is combined with the three-axis movable platform 76 to mark the surface of the foil. The marking pen 773 on the fixed flange 772 is controlled by an electric telescopic rod 771 to telescope, making it easier to mark the foil in the corners of the inspection window 72 and increasing the marking range. After the aluminum foil is installed between the release drum 2 and the recovery drum 4, a clamping mechanism 3 is installed on the edge of the inspection box 10 to ensure the foil's tension. During clamping, the movement of telescopic cylinder 1 38 is controlled, causing tension pulley 37 to move within horizontal guide rail 36, thereby pulling drive belt 35. This in turn forces the pulleys 34 at the ends of clamping roller 1 31 and clamping roller 2 32 toward each other, bringing clamping roller 1 31 and clamping roller 2 32 closer together, thus clamping the aluminum foil. The travel motor 54 drives the right-angle frame 57 to move to the end of the inspection box 10 near the release cylinder 2. The rotating motor 56 drives the rotating frame 55 and the right-angle frame 57 to rotate to a vertical position, and the edge of the aluminum foil is fixed to a right-angled side of the right-angle frame 57. Then, the travel motor 54 drives the aluminum foil across the inspection box 10 to the end near the recovery cylinder 4, and the aluminum foil is fixed to the recovery cylinder 4. The recovery motor 40 continuously pulls the aluminum foil on the release cylinder 2 into the inspection box 10 for inspection. After the aluminum foil reaches the recovery cylinder 4, the rotating motor 56 controls the rotating frame 55 and the right-angle frame 57 to rotate to a horizontal position to avoid interfering with the movement of the aluminum foil and the subsequent detection and marking mechanism 7. The movement of the pressing plate 510 is controlled by the telescopic cylinder 2 513. When the aluminum foil moves between the pressing plate 510 and the right-angle frame 57, the telescopic cylinder 2 513 is used to control the pressing plate 510 and the right-angle frame 57 to move closer to 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 center 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 center 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 achieve double-sided detection, thereby improving the detection efficiency and detection integrity.
