Description

Technical Field

[0001] This utility model relates to the field of aluminum foil production technology, and in particular to an aluminum foil pattern detection device. Background Technology

[0002] The flatness of aluminum foil is an indicator of the overall flatness of the foil surface. Specifically, the flatness of the aluminum foil surface is tested using a flatness tester to generate a test report, thereby analyzing whether the aluminum foil surface meets the requirements.

[0003] In aluminum foil pattern inspection, the centering of the sample aluminum foil on the pattern instrument is one of the key factors affecting the test results. Current technology for detecting whether the sample aluminum foil is centered on the pattern instrument involves manually measuring the distance between the edge of the aluminum foil and the instrument's baseline multiple times using a measuring tape, comparing the data from both sides of the sample aluminum foil to determine if it is centered.

[0004] While the above method can determine whether the sample aluminum foil is centered on the pattern setter, it requires manual measurement with a tape measure. This is not only time-consuming and inefficient, but also cannot meet the real-time inspection requirements of continuous production. In addition, tape measure measurement is easily affected by human reading errors, and it is difficult to accurately position the aluminum foil when it is running at high speed. Furthermore, if the offset is not detected in time, it may cause the aluminum foil to be too tight on one side, resulting in breakage, or too loose on the other side, resulting in wrinkles, thus making the aluminum foil unqualified. Utility Model Content

[0013] A spacing adjustment assembly includes multiple sets of adjustment rollers arranged along a first direction with different spacings; each set of adjustment rollers includes a first adjustment roller and a second adjustment roller whose two ends are respectively supported by two support plates and formed a rotatable connection.

[0014] The pattern detection component includes a slider located between a first adjusting roller and a second adjusting roller, and a distance sensor that is slidably connected to the slider. The two ends of the slider are respectively supported by the two support plates and are fixedly connected.

[0015] The second air expansion roller has its two ends supported by the support plate and forming a rotatable connection.

[0016] A drive motor is fixed to one side of the second bracket, and the output shaft of the drive motor is connected to one end of the second air expansion roller to drive the second air expansion roller to rotate.

[0017] The first air-expanding roller, the scale, the first guide roller, the second guide roller, the first adjusting roller, the sliding member, the second adjusting roller, and the second air-expanding roller are parallel to each other and arranged sequentially along the first direction with intervals between them; the first air-expanding roller is used to wind up and unwind the aluminum foil to be tested, and the second air-expanding roller is used to wind up and rewind the tested aluminum foil; during testing, the aluminum foil to be tested sequentially abuts against the first guide roller, the second guide roller, the first adjusting roller, the second adjusting roller, and the second air-expanding roller, the scale is located on the side of the aluminum foil to be tested away from the base plate and is arranged with intervals between them, and the distance sensor is located on the side of the aluminum foil to be tested away from the second support and is arranged with intervals between them.

[0018] Preferably, the aluminum foil pattern detection device further includes a third guide roller arranged parallel to the first guide roller. The two ends of the third guide roller are respectively supported by the two side plates and form a rotatable connection. The third guide roller is located between the first air expansion roller and the first guide roller and is closer to the base plate relative to the first guide roller.

[0019] Preferably, the aluminum foil pattern detection device further includes a plurality of fourth guide rollers, which are respectively spaced between the first guide roller and the first adjusting roller and are all parallel to the first guide roller. The two ends of each fourth guide roller are respectively supported by two support plates and form a rotatable connection.

[0020] Preferably, the aluminum foil pattern detection device further includes a plurality of fifth guide rollers, which are respectively spaced between the second adjusting roller and the second air expansion roller and are all parallel to the second adjusting roller. The two ends of each fifth guide roller are respectively supported by two support plates and form a rotatable connection.

[0021] Preferably, the first guide roller, the second guide roller, the third guide roller, the fourth guide roller, the fifth guide roller, the first adjusting roller, and the second adjusting roller are all aluminum alloy rollers.

[0025] Compared with the prior art, the aluminum foil pattern detection device of this utility model adds a scale that is supported at both ends by two side plates and forms a rotatable connection. During detection, the scale is positioned on the side of the aluminum foil to be detected away from the base plate and the two are spaced apart. When the aluminum foil to be detected needs to be detected, the aluminum foil to be detected is first brought into contact with the first guide roller, the second guide roller, the first adjusting roller, the second adjusting roller and the second air expansion roller in sequence. The aluminum foil to be detected is brought into a low pretension state by adjusting the drive electrode. Even if the aluminum foil to be detected is slightly taut, the operator can determine whether the aluminum foil to be detected is centered by observing the distance between the edge of the aluminum foil to be detected and the scale. The operator can also manually adjust the aluminum foil to be centered. After the aluminum foil to be detected is centered, the drive motor is adjusted to a normal detection tension state, thereby performing pattern detection on the aluminum foil to be detected. This method of directly adding a ruler to determine whether the aluminum foil to be tested is centered does not rely on a measuring tape. It not only reduces the operation time but also quickly confirms the centering status, making it more efficient and meeting the real-time inspection needs of continuous production. At the same time, it is less affected by human reading errors and can quickly and accurately locate the foil. In addition, this method of confirming centering is done when the aluminum foil to be tested is under low pretension, which will not result in one side of the aluminum foil being too tight and the other side being too loose, thus ensuring the pass rate of the aluminum foil.

[0034] 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.

[0035] This utility model embodiment provides an aluminum foil pattern detection device 100, combined with... Figures 1 to 3As shown, it includes a first support 1, a first air roller 2, a scale 3, a first guide roller 4, a second support 5, a pressure detection component, a spacing adjustment component, a pattern detection component, a second air roller 9, and a drive motor (not shown).

[0036] The aluminum foil pattern detection device 100 is used to detect the pattern of aluminum foil.

[0037] like Figure 2 As shown, the first bracket 1 includes a base plate 101, side plates 102 that are bent and extended from opposite sides of the base plate 101 and perpendicular to the base plate 101, and a fixing plate 103 that is bent and extended from the other side of the base plate 101 and perpendicular to the base plate 101. The opposite sides of the fixing plate 103 are respectively fixed to the same side of the two side plates 102.

[0038] The two ends of the first air-expanding roller 2 are respectively supported on the two side plates 102 and form a rotatable connection; the two ends of the scale 3 are respectively supported on the two side plates 102 and form a fixed connection; the two ends of the first guide roller 4 are respectively supported on the two side plates 102 and form a rotatable connection; the first air-expanding roller 2, the scale 3 and the first guide roller 4 are spaced apart from each other and arranged sequentially along the first direction.

[0039] The second bracket 5 is fixed to the side of the fixing plate 103 away from the base plate 101 and extends along the first direction. The second bracket 5 has support plates 51 parallel to the side plates 102 on opposite sides along the first direction, with each support plate 51 lying on the same plane as its corresponding side plate 102. The first direction is... Figure 1 The X-axis in the equation.

[0040] The pressure detection assembly includes a second guide roller 6 with its two ends rotatably connected to two support plates 51, and a pressure sensor (not shown) fixed to one or both ends of the second guide roller 6.

[0041] The spacing adjustment assembly includes multiple sets of adjustment rollers arranged along a first direction with different spacings; each set of adjustment rollers includes a first adjustment roller 7 and a second adjustment roller 8 whose two ends are respectively supported by two support plates 51 and formed a rotatable connection.

[0042] The pattern detection component (not shown) includes a slider located between the first adjusting roller 7 and the second adjusting roller 8, and a distance sensor that is slidably connected to the slider. The two ends of the slider are respectively supported on two support plates 51 and are fixedly connected.

[0043] The two ends of the second air-expanding roller 9 are respectively supported by two support plates 51 and formed a rotatable connection; the drive motor is fixed to one side of the second bracket 5 parallel to any one of the support plates 51, and the output shaft of the drive motor is connected to one end of the second air-expanding roller 9 to drive the second air-expanding roller 9 to rotate. When winding aluminum foil, the second air-expanding roller 9 can be expanded by inflation to achieve rapid winding or unwinding.

[0044] The first air expansion roller 2, scale 3, first guide roller 4, second guide roller 6, first adjusting roller 7, sliding member, second adjusting roller 8, and second air expansion roller 9 are parallel to each other and arranged sequentially along the first direction with intervals between each other; the first air expansion roller 2 is used to wind up the aluminum foil to be tested and unwind it, and the second air expansion roller 9 is used to wind up the tested aluminum foil and rewind it. In addition, after the test, the second air expansion roller 9 is also used to unwind it.

[0045] The first air-expanding roller 2 and the second air-expanding roller 9 can also be called air-expanding shafts; the first guide roller 4 to the fifth guide roller 12, the first adjusting roller 7 and the second adjusting roller 8 are cylindrical rods or shafts, etc.

[0046] During testing, the aluminum foil to be tested is sequentially pressed against the first guide roller 4, the second guide roller 6, the first adjusting roller 7, the second adjusting roller 8, and the second air expansion roller 9. The scale 3 is located on the side of the aluminum foil to be tested away from the base plate 101 and the two are spaced apart from each other. The distance sensor is located on the side of the aluminum foil to be tested away from the second support 5 and the two are spaced apart from each other.

[0047] In this embodiment, the scale values ​​of ruler 3 gradually increase from 0 at both ends towards the middle. That is, the left and right sides of ruler 3 are both 0, and the scale values ​​extending to the middle on both sides are 500mm. This means the scale values ​​of ruler 3 are symmetrically arranged along a center line perpendicular to the extension direction of ruler 3. Each graduation on ruler 3 is 1mm, with a short graduation 32 every 5mm and a long graduation 31 every 10mm, each marked with a number. This design allows for more precise determination of the distance from the edge of the aluminum foil to be tested to the edge of the graduation. Of course, the graduation distance and parameters on ruler 3 can be adjusted adaptively according to actual needs.

[0048] The surface of ruler 3 is uniformly coated with epoxy resin, which improves the wear resistance of ruler 3.

[0049] The distance between the scale 3 and the roller surface of the first air-expanding roller 2 is approximately 80mm. This design ensures that the scale 3 does not directly contact the aluminum foil being tested, nor is it too far away from the aluminum foil.

[0050] In this embodiment, there are two pressure sensors, which are fixed at both ends of the second guide roller 6. This design can better obtain the pressure value of the aluminum foil to be tested, so that the tension of the aluminum foil to be tested can be adjusted in real time by adjusting the speed of the drive motor, so that it will not be tight on one side and loose on the other.

[0051] In this embodiment, the first adjusting roller 7 in the spacing adjustment assembly includes three rollers: 7a, 7b, and 7c. The second adjusting roller 8 in the spacing adjustment assembly includes three rollers: 8a, 8b, and 8c. The first adjusting roller 7a and the second adjusting roller 8a form a first group of adjusting rollers for a first spacing, the first adjusting roller 7b and the second adjusting roller 8b form a second group of adjusting rollers for a second spacing, and the first adjusting roller 7c and the second adjusting roller 8c form a third group of adjusting rollers for a third spacing. The first spacing is smaller than the second spacing, and the second spacing is smaller than the third spacing.

[0052] In this embodiment, the sliding element can be a lead screw or a motor in conjunction with a telescopic rod, so that the distance sensor can slide from one edge of the aluminum foil to be detected to the other edge; the distance sensor can be an infrared sensor for distance detection.

[0053] like Figure 2 As shown, the aluminum foil pattern detection device 100 also includes a third guide roller 10 arranged parallel to the first guide roller 4. The two ends of the third guide roller 10 are respectively supported by two side plates 102 and form a rotatable connection. The third guide roller 10 is located between the first air expansion roller 2 and the first guide roller 4 and is closer to the base plate 101 than the first guide roller 4.

[0054] like Figure 1 As shown, the aluminum foil pattern detection device 100 also includes a plurality of fourth guide rollers 11. The plurality of fourth guide rollers 11 are respectively spaced between the first guide roller 4 and the first adjusting roller 7 and are all parallel to the first guide roller 4. The two ends of each fourth guide roller 11 are respectively supported by two support plates 51 and form a rotatable connection. This design can better support the aluminum foil to be detected. In this embodiment, there are two fourth guide rollers 11.

[0055] like Figure 1 As shown, the aluminum foil pattern detection device 100 also includes a plurality of fifth guide rollers 12. The plurality of fifth guide rollers 12 are respectively spaced between the second adjusting roller 8 and the second air expansion roller 9 and are all parallel to the second adjusting roller 8. The two ends of each fifth guide roller 12 are respectively supported by two support plates 51 and form a rotatable connection. This design can better support the aluminum foil to be detected. In this embodiment, there are two fifth guide rollers 12.

[0056] The first guide roller 4, the second guide roller 6, the third guide roller 10, the fourth guide roller 11, the fifth guide roller 12, the first adjusting roller 7, and the second adjusting roller 8 are all made of 6061 aluminum alloy. This design can improve the structural strength of the guide rollers. The diameter of the first guide roller 4, the second guide roller 6, the third guide roller 10, the fourth guide roller 11, the fifth guide roller 12, the first adjusting roller 7, and the second adjusting roller 8 is 30mm, and the length is 1800mm. At this time, the width of the aluminum foil pattern detection device 100 is 1800mm. Of course, the diameter and length can be adjusted accordingly according to actual needs.

[0057] The side of the scale 3 and each guide roller closest to the base plate 101 is defined as the bottom, and the side of the scale 3 and each guide roller away from the base plate 101 is defined as the top. In this embodiment, when the aluminum foil pattern detection device 100 is used for detection, the aluminum foil on the first air-expansion roller 2 is manually passed sequentially through the following: below the third guide roller 10, above the first guide roller 4, above the second guide roller 6, below the fourth guide roller 11 near the second guide roller 6, above the fourth guide roller 11 away from the second guide roller 6, below one of the first adjusting rollers 7, above the second adjusting roller 8 corresponding to the first adjusting roller 7, and above the fifth guide roller 12 near the second adjusting roller 8. Below the second air expansion roller 9, above the fifth guide roller 12 away from the second adjustment cabinet, and below the second air expansion roller 9, ensuring that the aluminum foil to be tested is not loose or damaged at the edges, and that the aluminum foil to be tested is smooth and not twisted; at the same time, ensure that during the threading process, the aluminum foil pattern detection device 100 is in a low tension state or a loose operation state, to avoid the aluminum foil to be tested from deforming or breaking due to excessive tension. The low tension state is 10-30% of the normal detection tension state, which can be achieved by controlling the drive motor; at this time, it is necessary to ensure that the aluminum foil to be tested is transmitted along the center line of the aluminum foil pattern detection device 100 to avoid affecting the detection accuracy due to offset.

[0058] Once preparation is complete, the operator can directly observe the scale on ruler 3 and record the distance between the edge of the aluminum foil to be tested and the left and right scales of ruler 3. If the distance between the left and right scales of ruler 3 is the same or the deviation is less than or equal to 10mm, the aluminum foil to be tested can be determined to be centered. If the distance between the left and right scales of ruler 3 is greater than 10mm, manual adjustment is required until the aluminum foil to be tested is centered. If the aluminum foil to be tested on the other guide rollers appears to have a large deviation from the naked eye, it is necessary to check whether the corresponding guide roller is parallel to the other guide rollers until all the aluminum foils to be tested are centered.

[0059] Once the aluminum foil to be inspected is determined to be centered, the aluminum foil pattern inspection device 100 is put into normal inspection mode, such as 0.6 KGF / mm. 2This allows for pattern detection of the aluminum foil to be inspected. During pattern detection, an infrared sensor slides along the lead screw and detects the distance of the aluminum foil to be inspected to determine whether the distances at various points on the aluminum foil to be inspected are the same. If they are the same, it can be determined that the pattern of the aluminum foil to be inspected meets the requirements; if they are different, it can be determined that the pattern of the aluminum foil to be inspected does not meet the requirements.

[0060] Compared with the prior art, the aluminum foil pattern detection device 100 of this utility model adds a scale 3 that is supported at both ends by two side plates 102 and forms a rotatable connection. During detection, the scale 3 is positioned on the side of the aluminum foil to be detected away from the base plate 101 and the two are spaced apart. In this way, when the aluminum foil to be detected needs to be detected, the aluminum foil to be detected is first brought into contact with the first guide roller 4, the second guide roller 6, the first adjusting roller 7, the second adjusting roller 8 and the second air expansion roller 9 in sequence. The aluminum foil to be detected is brought into a low pretension state by adjusting the drive electrode. Even if the aluminum foil to be detected is slightly taut, the operator can determine whether the aluminum foil to be detected is centered by observing the distance between the edge of the aluminum foil to be detected and the scale on the scale 3, or manually adjust the aluminum foil to be centered. After the aluminum foil to be detected is centered, the drive motor is adjusted to be in a normal detection tension state, thereby performing pattern detection on the aluminum foil to be detected. This method of directly adding a ruler 3 to determine whether the aluminum foil to be inspected is centered does not rely on a measuring tape. It not only reduces the operation time but also quickly confirms the centering state, making it more efficient and meeting the real-time inspection needs of continuous production. At the same time, it is less affected by human reading errors and can quickly and accurately locate the foil. In addition, this method of confirming centering is done when the aluminum foil to be inspected is in a low pretension state, which will not result in one side of the aluminum foil being too tight and the other side being too loose, thus ensuring the pass rate of the aluminum foil.

[0061] It should be noted that the various embodiments described above with reference to the accompanying drawings are only illustrative of the present invention and not intended to limit its scope. Those skilled in the art should understand that any modifications or equivalent substitutions made to the present invention without departing from its spirit and scope should be covered within the scope of the present invention. Furthermore, unless the context otherwise requires, singular terms include plural forms, and vice versa. Additionally, unless specifically stated otherwise, all or part of any embodiment may be used in conjunction with all or part of any other embodiment.
