[0002] Formed foil is the core raw material for aluminum electrolytic capacitors. Its production is achieved through etching and formation processes: the etching process forms dense micropores on the surface of the aluminum foil to increase the specific surface area, while the formation process generates a uniform dielectric oxide film on the surface of the micropores through electrochemical oxidation, giving it insulation and energy storage properties. Finished product testing aims to verify the performance compliance of the formed foil: the testing covers indicators such as thickness uniformity, surface roughness, and mechanical strength to ensure processing suitability, etc., and each step relies on professional instruments to achieve standardized quality control.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: an adjustable chemically deposited foil defect detection device, including an unwinding mechanism 1, which is located on the top side of a base plate 2. A first detection mechanism 3 is located on the top side of the base plate 2 near the unwinding mechanism 1. A support frame A4 is located on the top side of the base plate 2 near the first detection mechanism 3. A second detection mechanism 5 is vertically inserted through the top two sides of the support frame A4. A support frame B6 is located on the top side of the base plate 2 near the second detection mechanism 5. A groove 7 is opened on the top of the support frame B6. An adjustment mechanism 8 is rotatably connected to the inner walls of the left and right sides of the groove 7. A third detection mechanism 9 is located at the bottom of the adjustment mechanism 8. A winding mechanism 10 is located on the other side of the top of the base plate 2.

[0023] In this embodiment, as Figure 1 and Figure 2 As shown, the unwinding mechanism 1 includes two fixed frame plates A101, and the unwinding rollers 102 are rotatably connected to the opposite sides of the two fixed frame plates A101.

[0024] In this embodiment, as Figure 1 and Figure 3As shown, the first detection mechanism 3 includes a fixed frame 301. The bottom of the fixed frame 301 is located on the top of the base plate 2 near the unwinding mechanism 1. Two laser emitters 302 are provided on both sides of the top wall of the fixed frame 301, and two laser receivers 303 are provided on both sides of the bottom wall of the fixed frame 301. The two laser emitters 302 and the two laser receivers 303 are vertically corresponding to each other.

[0025] In this embodiment, as Figure 1 and Figure 4 As shown, the second detection mechanism 5 includes two electric telescopic rods 501. The drive ends of the two electric telescopic rods 501 are respectively perpendicularly inserted through the top two sides of the support frame A4. The drive ends of the electric telescopic rods 501 are provided with mounting brackets 502. A CCD camera 503 is installed inside the mounting bracket 502. The mounting bracket 502 and the CCD camera 503 are set at an inclined angle.

[0026] In this embodiment, as Figure 1 and Figure 5 As shown, the adjustment mechanism 8 includes a segmented multi-directional screw 801. The two ends of the segmented multi-directional screw 801 are rotatably connected to the inner walls of the left and right sides of the slide groove 7, respectively. Several sliders 802 are screwed onto the outer wall of the segmented multi-directional screw 801, and a stepper motor 803 is inserted into one end of the segmented multi-directional screw 801.

[0027] In this embodiment, as Figure 1 and Figure 5 As shown, the third detection mechanism 9 includes several mounting brackets 901, the top of which is located at the bottom of several sliders 802, and the bottom inner wall of the mounting bracket 901 is fitted with an eddy current probe 902.

[0028] In this embodiment, as Figure 2 As shown, the winding mechanism 10 includes a winding roller 1001. The two ends of the winding roller 1001 are rotatably connected to the opposite sides of two fixed frame plates B1002. A drive motor 1003 is inserted into one end of the winding roller 1001. Tension sensors 1004 are installed on the outer walls of both ends of the winding roller 1001.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the adjustable electrolytic foil defect detection device operates as follows during use:

[0030] First, the operator can install the chemically formed foil roll to be tested on the unwinding roller 102 of the unwinding mechanism 1, and then fix one end of the chemically formed foil roll to the outer wall of the take-up roller 1001. At the same time, the drive motor 1003 can be started to drive the take-up roller 1001 connected to it to start rotating, so that the chemically formed foil on the outer wall of the take-up roller 1001 starts to be wound up for testing. During this period, the tension sensor 1004 (U9B) will monitor the tension of the foil in real time and feed the data back to the drive motor 1003, thereby automatically adjusting the winding speed to ensure that the foil is wound flat and avoids damage due to excessive tension or loosening due to insufficient tension.

[0031] During the winding process of the electroforming foil, it first passes through the first detection mechanism 3. During this process, two laser emitters 302 (LD) located on the top wall of the fixed frame 301 will synchronously emit lasers downwards, while two laser receivers 303 (PD) located on the bottom wall of the fixed frame 301 will receive the lasers vertically. When the electroforming foil passes between the laser emitters 302 (LD) and the laser receivers 303 (PD), if the foil has problems such as uneven thickness, holes or edge defects, it will block or change the laser transmission path. During this process, the laser receivers 303 will detect the signal changes in real time and determine whether there are surface or contour defects.

[0032] After being inspected by the first inspection agency 3, the foil will continue to move under the support frame A4. Before this, the operator can adjust the height of the mounting bracket 502 located at the drive end of the electric telescopic rod 501 by activating it according to the thickness of the foil. This allows the CCD camera 503 inside the mounting bracket 502 to maintain a suitable distance from the foil. When the foil enters the shooting range of the CCD camera 503, the CCD camera 503 can capture a comprehensive image of the foil surface due to the appropriate tilt angle, thereby detecting surface defects such as scratches, spots, and wrinkles. During this process, the CCD camera 503 will collect images in real time and transmit them to the control system for analysis.

[0033] After the second inspection mechanism 5 completes the inspection, the foil will continue to be conveyed forward to the underside of the support frame B6. At this time, the operator can start the stepper motor 803 according to the width of the formed foil or the inspection requirements, so that it drives the segmented multi-directional screw 801 that is plugged into it to start rotating. This allows the several sliders 802 screwed to its outer wall to set their respective thread directions to spread out or concentrate, thereby adjusting the spacing of the multiple third inspection mechanisms 9 at the bottom of the sliders 802 to adapt to different widths of the formed foil. After the adjustment is completed, the multiple eddy current probes 902 (NORTEC-600) will be evenly distributed above the foil, so as to detect internal defects of the foil. During this period, the eddy current probes 902 (NORTEC-600) will scan the foil in real time through the principle of electromagnetic induction. When abnormalities such as uneven conductive layer or internal cracks are detected, a signal will be fed back to the control system in a timely manner.

[0034] After the first inspection mechanism 3, the second inspection mechanism 5 and the third inspection mechanism 9 are completed in sequence, the foil that has been inspected will be wound up on the outer wall of the winding roller 1001. At this time, the operator can remove the whole roll of foil and continue to carry out the next inspection operation.
