Description

Technical Field

[0001] This utility model relates to the field of chemically formed foil detection technology, and more specifically to a high-precision instrument for detecting the thickness of chemically formed foil. Background Technology

[0002] Formed foil is a core material for aluminum electrolytic capacitors. It is formed by electrochemical etching and oxidation of high-purity aluminum foil under specific conditions to create a dielectric oxide layer with a huge specific surface area. The thickness, uniformity, and consistency of this microstructure directly determine the capacitor's core performance parameters such as rated voltage, capacitance, and leakage current, as well as the reliability of the final product. Therefore, accurate and reliable detection and control of the formed foil thickness during the production process is a crucial step in ensuring the quality of capacitor products.

[0003] Currently, industrial methods for measuring foil thickness are mainly divided into two categories: contact and non-contact. Contact measurement methods rely on micrometers or other means to contact the formed foil material to measure its thickness. Non-contact measurement methods use thickness gauges based on eddy current and ultrasonic principles to measure the thickness of foil material.

[0004] Currently, contact testing methods can damage the foil, while non-contact testing methods are affected by the foil's own movement, leading to errors in the test results. Furthermore, if the foil surface is covered with dust or has wrinkles, the test results will also have significant errors. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an instrument for high-precision detection of the thickness of chemically formed foil, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a high-precision instrument for detecting the thickness of electrolytic foil, including a feeding roller, a receiving roller on the side of the feeding roller, a detection mechanism between the feeding roller and the receiving roller, and a cleaning mechanism on the side of the detection mechanism near the feeding roller; the cleaning mechanism includes a first cleaning component for cleaning, the first cleaning component includes a support rod for support, an upper fixing plate is fixedly connected to the top of the support rod, an upper support plate is fixedly connected to the side of the upper fixing plate, an upper cleaning plate is fixedly connected to the bottom of the upper support plate, a lower fixing plate is fixedly connected to the side of the support rod, a lower support plate is fixedly connected to the side of the lower fixing plate, and a lower cleaning plate is fixedly connected to the top of the lower support plate.

[0007] Furthermore, the feeding roller is provided with a first support frame on the side near the detection mechanism, and the receiving roller is provided with a second support frame on the side near the detection mechanism. The first support frame and the second support frame have the same structure, and the foil passes through the first support frame and the second support frame.

[0008] Furthermore, a second cleaning component is provided on the side of the first cleaning component near the detection mechanism. The first cleaning component and the second cleaning component have the same structure. The upper cleaning plate and the lower cleaning plate have the same structure, and the upper cleaning plate and the lower cleaning plate are located at the top and bottom of the foil.

[0009] Furthermore, the detection mechanism includes a fixed base for support, a support column is fixedly connected to the top of the fixed base, a connecting plate is fixedly connected to the top of the support column, a detection plate is fixedly connected to the side of the connecting plate, and a laser detector and a fan assembly are fixedly connected to the top of the fixed base.

[0010] Furthermore, there are two fan assemblies and three laser detectors. The two fan assemblies are distributed among the three laser detectors, and the laser detectors and fan assemblies are located below the detection plate.

[0011] Furthermore, the fan assembly includes a fixed frame for fixed support, a servo motor is fixedly connected to the bottom of the fixed frame, an output shaft is fixedly connected to the top of the servo motor, and a blade assembly is fixedly connected to the top of the output shaft.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model includes a first cleaning component, a second cleaning component, an upper cleaning plate, and a lower cleaning plate. When the foil material is tested, it passes through the first cleaning component and the second cleaning component. The first cleaning component and the second cleaning component can clean both sides of the surface, thereby ensuring the cleaning effect. During cleaning, the upper cleaning plate and the lower cleaning plate contact the top and bottom of the foil material respectively, thereby cleaning both sides of the foil material and ensuring the accuracy of subsequent thickness testing.

[0014] 2. This utility model uses a detection plate and a laser detector. When the cleaned foil passes under the detection plate, the fan assembly starts and blows air upward, so that the foil completely adheres to the bottom of the detection plate. At this time, the foil is flat and in contact with the detection plate. When in contact, the laser detector detects the distance between itself and the foil and the bottom of the detection plate. The difference in distance is the thickness of the foil. This allows for accurate detection without damaging the foil. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1 This utility model provides a high-precision instrument for detecting the thickness of chemically formed foil, including a feeding roller 1, a receiving roller 2 on the side of the feeding roller 1, a detection mechanism 6 between the feeding roller 1 and the receiving roller 2, a cleaning mechanism 5 on the side of the detection mechanism 6 near the feeding roller 1, a first support frame 3 on the side of the feeding roller 1 near the detection mechanism 6, and a second support frame 4 on the side of the receiving roller 2 near the detection mechanism 6. The first support frame 3 and the second support frame 4 have the same structure, and the foil passes through the first support frame 3 and the second support frame 4.

[0023] In this embodiment, the foil passes through the first support frame 3 and the second support frame 4. The first support frame 3 and the second support frame 4 keep the foil in a stable horizontal state, and the position of the foil is closer to the bottom of the detection plate 604 in the detection mechanism 6, so that the foil is blown to the bottom of the detection plate 604 by the fan assembly 606 more stably.

[0024] Reference Figure 2 and Figure 3 The cleaning mechanism 5 includes a first cleaning component 501 for cleaning. The first cleaning component 501 includes a support rod 5011 for support. An upper fixing plate 5012 is fixedly connected to the top of the support rod 5011. An upper support plate 5013 is fixedly connected to the side of the upper fixing plate 5012. An upper cleaning plate 5014 is fixedly connected to the bottom of the upper support plate 5013. A lower fixing plate 5015 is fixedly connected to the side of the support rod 5011. A lower support plate 5016 is fixedly connected to the side of the lower fixing plate 5015. A lower cleaning plate 5017 is fixedly connected to the top of the lower support plate 5016. A second cleaning component 502 is provided on the side of the first cleaning component 501 near the detection mechanism 6. The first cleaning component 501 and the second cleaning component 502 have the same structure. The upper cleaning plate 5014 and the lower cleaning plate 5017 have the same structure, and the upper cleaning plate 5014 and the lower cleaning plate 5017 are located at the top and bottom of the foil.

[0025] In this embodiment, the bottom end of the upper cleaning plate 5014 contacts the top end of the foil, and the top end of the 6017 contacts the bottom end of the foil, thereby cleaning both sides of the foil. The foil will not contain impurities that would affect the cleaning and detection of the foil and the detection plate 604. Furthermore, the foil will be cleaned twice by the first cleaning component 501 and the second cleaning component 502, resulting in a better cleaning effect.

[0026] Reference Figure 4 and Figure 5 The detection mechanism 6 includes a fixed base 601 for support. A support column 602 is fixedly connected to the top of the fixed base 601. A connecting plate 603 is fixedly connected to the top of the support column 602. A detection plate 604 is fixedly connected to the side of the connecting plate 603. A laser detector 605 and a fan assembly 606 are fixedly connected to the top of the fixed base 601. There are two fan assemblies 606 and three laser detectors 605. The two fan assemblies 606 are distributed among the three laser detectors 605. The laser detectors 605 and the fan assemblies 606 are located below the detection plate 604. The fan assembly 606 includes a fixed frame 6061 for fixed support. A servo motor 6062 is fixedly connected to the bottom of the fixed frame 6061. An output shaft 6063 is fixedly connected to the top of the servo motor 6062. A blade assembly 6064 is fixedly connected to the top of the output shaft 6063.

[0027] In this embodiment, when the servo motor 6062 drives the blade assembly 6064 to rotate via the output shaft 6063, it blows air upwards, causing the foil to move upwards under the action of the airflow and adhere to the bottom of the detection plate 604. The laser detector 605 detects the distance between itself and the detection plate 604 and the distance between itself and the foil. The difference between the two is the thickness of the foil, thereby accurately detecting the thickness of the foil without directly contacting it and avoiding damage to the foil. Two fan assemblies 606 are provided to achieve a better blowing effect, while three fan assemblies 606 can avoid this.

[0028] The working principle of this utility model is as follows: the feeding roller 1 releases the foil, the taking-up roller 2 winds up the foil, and when the foil is wrapped around the side of the feeding roller 1 and the taking-up roller 2, the foil will pass through the first support frame 3 and the second support frame 4. The first support frame 3 and the second support frame 4 make the foil stable in a horizontal state, so that the foil is blown by the fan assembly 606 to the bottom of the detection plate 604 more stably.

[0029] When the foil moves, it will be cleaned twice by the first cleaning component 501 and the second cleaning component 502 to ensure its cleaning effect. During cleaning, the bottom end of the upper cleaning plate 5014 contacts the top end of the foil, and the top end of 6017 contacts the bottom end of the foil, thereby cleaning both sides of the foil respectively. There will be no impurities on the foil that will affect the cleaning of the foil and the detection plate 604 and the detection.

[0030] When the foil passes under the detection plate 604, the servo motor 6062 starts and drives the output shaft 6063 to rotate. When the output shaft 6063 rotates, it drives the blade assembly 6064 to rotate. When the blade assembly 6064 rotates, it blows air upward, causing the foil to move upward under the action of the air force and stick to the bottom of the detection plate 604. The laser detector 605 detects the distance between itself and the detection plate 604 and the distance between itself and the foil. The difference between the two is the thickness of the foil, thus accurately detecting the thickness of the foil without directly contacting the foil and avoiding damage to the foil.

[0031] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
