Description

Technical Field

[0001] This utility model relates to the field of aluminum foil testing technology, specifically an aluminum foil testing device with a correction mechanism. Background Technology

[0002] Aluminum foil is an extremely thin metallic material made from high-purity aluminum through rolling, typically ranging from 0.006 to 0.2 millimeters in thickness. It possesses excellent ductility, electrical conductivity, thermal conductivity, and barrier properties. Its smooth surface and high reflectivity effectively block light, oxygen, moisture, and microorganisms. Newly produced aluminum foil requires surface inspection for defects.

[0003] In the prior art, the authorized announcement number CN211179561U discloses an online appearance image inspection device for carbon-coated foil printing, including a light source, a first CCD camera for acquiring images of a first surface of the carbon-coated foil and located above the first surface, and a second CCD camera for acquiring images of a second surface of the carbon-coated foil and located below the second surface, wherein the light emitted by the light source is directed toward the carbon-coated foil.

[0004] The aforementioned device inspects both sides of the aluminum foil using a CCD camera. To achieve accurate inspection of both sides, two sets of CCD cameras are required. While this approach provides comprehensive inspection coverage, it also incurs higher costs. Furthermore, during actual inspection, the aluminum foil may not align precisely with the CCD camera for various reasons, resulting in tilted images. Image tilt negatively impacts subsequent inspection accuracy, thus affecting the accuracy and reliability of the entire inspection process. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum foil inspection device with a correction mechanism to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum foil inspection device with a correction mechanism, comprising a device base and an aluminum foil strip, a positioning sleeve fixedly installed on the device base, a movable sliding groove formed on the inner wall of the positioning sleeve, a correction mechanism installed on the positioning sleeve, the correction mechanism comprising a telescopic column slidably installed in the positioning sleeve and an adjusting screw rotatably installed in the positioning sleeve, a screw nut threaded onto the adjusting screw and fixedly installed on the telescopic column, a rotating base rotatably installed on the upper end of the telescopic column, and an inspection mechanism fixedly installed on the rotating base.

[0007] Preferably, the correction mechanism further includes a servo motor fixedly mounted on the equipment base, a small gear fixedly mounted at the output end of the servo motor, and a large gear fixedly mounted at the lower end of the adjusting screw.

[0008] Preferably, a bearing is installed at the bottom of the positioning sleeve, and the adjusting screw is rotatably mounted inside the positioning sleeve via the bearing.

[0009] Preferably, the small gear is rotatably mounted inside the equipment base via a servo motor, the large gear is rotatably mounted inside the equipment base via an adjusting screw, and the large gear meshes with the small gear. The detection mechanism is rotatably mounted on the upper end of the telescopic column via a rotating base.

[0010] Preferably, the detection mechanism includes a detection box fixedly installed on a rotating base. The detection box has inlet and outlet openings on both sides, and the aluminum foil strip passes through the inlet and outlet openings into the detection box. An upper plane mirror and a lower plane mirror are fixedly installed inside the detection box. A supplementary light is fixedly installed on the inner wall of the detection box. An installation port is opened on the detection box, and a CCD camera is fixedly installed in the installation port.

[0011] Preferably, the upper plane mirror faces the upper surface of the aluminum foil strip, the lower plane mirror faces the lower surface of the aluminum foil strip, and the angle between the two plane mirrors and the aluminum foil strip is 45°.

[0012] Preferably, the CCD camera is mounted on the detection chamber through the mounting port, and the detection chamber has a slot, through which the upper plane mirror and the lower plane mirror are fixed in the detection chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, after the servo motor starts, it drives the pinion to rotate. Subsequently, the rotation of the pinion drives the rotation of the large gear, which in turn causes the adjusting screw to rotate. The rotation of the adjusting screw causes the screw nut to move vertically, thereby realizing the lifting and lowering movement of the telescopic column. This movement adjusts the height of the detection chamber, allowing the aluminum foil strip to pass smoothly through the inlet and outlet openings of the detection chamber. After the aluminum foil strip passes through the detection chamber, the rotation of the rotating base can adjust the shooting angle of the CCD camera, ensuring that the CCD camera and the aluminum foil strip remain vertically aligned, thereby ensuring the quality of the captured image.

[0015] 2. In this application, the configuration of the upper and lower plane mirrors enables the reflection of images from the upper and lower surfaces of the aluminum foil strip, allowing a set of CCD cameras to accurately inspect both sides of the aluminum foil strip. During this inspection process, the illumination provided by the supplementary lighting ensures clear imaging of both sides of the aluminum foil strip, thereby guaranteeing high-quality imaging results.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an aluminum foil inspection device with a correction mechanism, including a device base 1 and an aluminum foil strip 4. A positioning sleeve 2 is fixedly installed on the device base 1. A movable sliding groove 3 is opened on the inner wall of the positioning sleeve 2. A correction mechanism 5 is installed on the positioning sleeve 2, and an inspection mechanism 6 is fixedly installed on the rotating base 501. The correction mechanism 5 can adjust the inspection box 601 to ensure the quality of the captured images. The inspection mechanism 6 only needs one set of CCD cameras 604 to inspect both sides of the aluminum foil strip 4.

[0023] like Figure 2 and Figure 3As shown, the correction mechanism 5 includes a telescopic column 502 slidably installed in the positioning sleeve 2 and an adjusting screw 503 rotatably installed in the positioning sleeve 2. A screw nut 504 is threaded onto the adjusting screw 503, and the screw nut 504 is fixedly installed on the telescopic column 502. A rotating base 501 is rotatably installed on the upper end of the telescopic column 502. The correction mechanism 5 also includes a servo motor 507 fixedly installed on the equipment base 1. A pinion 506 is fixedly installed at the output end of the servo motor 507. A large gear 505 is fixedly installed at the lower end of the adjusting screw 503. A bearing is installed at the bottom of the positioning sleeve 2, and the adjusting screw 503 is rotatably installed in the positioning sleeve 2 through the bearing.

[0024] Specifically, when the servo motor 507 is started, it drives the pinion 506 to rotate. As the pinion 506 rotates, it further drives the large gear 505 to rotate. The rotation of the large gear 505 causes the adjusting screw 503 to rotate. The rotation of the adjusting screw 503 causes the screw nut 504 to move up and down. The up and down movement of the screw nut 504 causes the telescopic column 502 to rise or fall. The rising or falling movement of the telescopic column 502 ultimately adjusts the height of the detection chamber 601. By adjusting the height of the detection chamber 601, the aluminum foil strip 4 can smoothly pass through the inlet / outlet notch 602 and through the detection chamber 601. After the aluminum foil strip 4 passes through the detection chamber 601, the rotating base 501 can be further operated to adjust the shooting angle of the CCD camera 604. By adjusting the shooting angle of the CCD camera 604, it can be ensured that the CCD camera 604 and the aluminum foil strip 4 remain vertically aligned. This alignment method is crucial for ensuring the quality of the photographs, as it guarantees sharpness and accuracy.

[0025] like Figure 2 and Figure 4 As shown, the detection mechanism 6 includes a detection box 601 fixedly installed on a rotating base 501. The detection box 601 has inlet and outlet openings 602 on both sides, and the aluminum foil strip 4 passes through the inlet and outlet openings 602 to pass through the detection box 601. An upper plane mirror 607 and a lower plane mirror 606 are fixedly installed inside the detection box 601. A supplementary light 605 is fixedly installed on the inner wall of the detection box 601. An installation port 603 is opened on the detection box 601, and a CCD camera 604 is fixedly installed inside the installation port 603. The upper plane mirror 607 faces the upper surface of the aluminum foil strip 4, and the lower plane mirror 606 faces the lower surface of the aluminum foil strip 4. The angle between the two plane mirrors and the aluminum foil strip 4 is 45°.

[0026] Specifically, by setting up the upper plane mirror 607 and the lower plane mirror 606, the images of the upper and lower surfaces of the aluminum foil strip 4 can be effectively reflected to the CCD camera 604. Using this CCD camera 604 configuration, both sides of the aluminum foil strip 4 can be comprehensively inspected. During the inspection process, the supplementary light 605 emits light that evenly illuminates both sides of the aluminum foil strip 4, ensuring that the captured images have good clarity and contrast, making the inspection results more accurate and reliable.

[0027] Working principle: First, start the servo motor 507. Starting the servo motor 507 will drive the pinion 506 to rotate. The pinion 506 will then drive the large gear 505 to rotate. The large gear 505 will then drive the adjusting screw 503 to rotate. The adjusting screw 503 will then drive the screw nut 504 to move up and down. This movement of the screw nut 504 will then drive the telescopic column 502 to rise or fall, thereby adjusting the height of the detection chamber 601. This allows the aluminum foil strip 4 to pass through the inlet / outlet 602 into the detection chamber 601. After passing through the detection chamber 601, the rotating base 501 can be rotated, thereby adjusting the shooting angle of the CCD camera 604. This ensures that the CCD camera 604 is perpendicularly aligned with the aluminum foil strip 4, guaranteeing the quality of the captured image. Furthermore, the upper plane mirror 607 and the lower plane mirror 606 can reflect the images of the upper and lower surfaces of the aluminum foil strip 4 to the CCD camera 604. Using a set of CCD cameras 604, both sides of the aluminum foil strip 4 can be inspected. During the inspection process, the light generated by the supplementary light 605 will illuminate both sides of the aluminum foil strip 4 to ensure the shooting effect.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
