Description

Technical Field

[0001] This invention relates to testing equipment technology, specifically to a device and method for testing the flatness of aluminum foil. Background Technology

[0002] During the production and processing of flexible metal parts, the flatness of their surfaces needs to be inspected. The measuring instrument is suitable for measuring the flatness of any planar object. Its principle is based on three evenly distributed measuring points on a plane centered on the measuring instrument. During measurement, sensors measure the height displacement difference from these three points. This data is collected and processed by a microcomputer and displayed on a screen, thus determining the flatness of the positions of these three points.

[0003] Flatness inspection is often used for the chassis of large equipment and the worktable of machine tools. Usually, a supporting surface is required to be in the same plane, which places certain requirements on the flatness of the object. Especially for high-precision machine tools, the equipment needs to be inspected for flatness before assembly. If the surface of the part exceeds the tolerance range, it will affect the working quality and efficiency of the equipment after installation.

[0004] Chinese patent CN216348527U discloses a flatness testing device for flexible metal parts. This device includes a cleaning component slidably mounted above a base. The cleaning component comprises a support plate, a spring seat, a slider, a cleaning plate, and cleaning swabs. Before flatness testing, the support plate of the cleaning component is pushed laterally along the base. The cleaning swabs on the lower surface of the cleaning plate wipe the upper surface of the flexible metal part, effectively removing debris and adsorbed dust, thus improving surface cleanliness. One end of a guide groove extends to the end face of the base, and a detachable baffle is connected above the guide groove near the opening. The baffle limits the movement of the cleaning component, facilitating assembly and disassembly and improving usability.

[0005] When existing equipment is in use, the surface of the aluminum foil may have dust, oil, fingerprints, oxide layer or other contaminants. In addition, wrinkles are easily generated on the surface of the aluminum foil during the inspection. This makes it easy for the inspection results to deviate from the predetermined data when the inspection is carried out in conjunction with electronic equipment. Therefore, a flatness inspection device and inspection method for aluminum foil has been developed. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0040] Please see Figures 1-8 A metal aluminum foil flatness detection device includes a base 1, with support columns 11 on both sides of the base 1. A cleaning component 12 is rotatably installed on the upper end of the support column 11, and the outer surface of the metal aluminum foil is cleaned by the cleaning component 12.

[0041] In this design, the inner wall of the support column 11 is equipped with a power output device such as a motor, which is connected to an external control device. When the motor starts, it synchronously drives the cleaning component 12 located at its output end to rotate, thereby cleaning the outer surface of the aluminum foil. The cleaning component 12 is a device with cleaning parts such as a roller.

[0042] Furthermore, a flipping component 2 is provided at the upper end of the base 1 to flip the metal aluminum foil. At the same time, a telescopic component 14 is provided on the inner wall of the base 1. A moving block 15 is provided at the output end of the telescopic component 14. A telescopic plate 13 is symmetrically provided at the upper end of the moving block 15. A stretching component 3 is provided at the end of the telescopic plate 13 to stretch the wrinkled part of the metal aluminum foil.

[0043] Specifically, the telescopic component 14 is an electric telescopic rod or other device with telescopic function, and is connected to an external control device. When the telescopic component 14 is started, it synchronously drives the moving block 15 set at its output end to move, which in turn cooperates with the telescopic plate 13 to drive the tensioning component 3 to adjust, so that the tensioning component 3 is in a suitable state.

[0044] The telescopic plate 13 is a device with telescopic function, such as an electric telescopic rod, and is connected to an external control device. At the same time, the height of the stretching component 3 can be adjusted by the telescopic plate 13 to ensure the overall neatness of the metal aluminum foil.

[0045] Furthermore, the tensioning assembly 3 includes a connecting block 31 connected to the telescopic plate 13. A screw 33 is provided at the end of the connecting block 31. A limit block 32 is slidably installed on the outer surface of the screw 33. At the same time, a sleeve 34 is provided at the end of the limit block 32. The end of the screw 33 passes through and extends into the inner cavity of the sleeve 34.

[0046] In this embodiment, the inner wall of the connecting block 31 is provided with a device with power output such as a motor, and is connected to an external control device. At the same time, when the motor starts, it synchronously drives the screw 33 provided at its output end to rotate.

[0047] The screw 33 is limited by the limiting block 32, thereby ensuring the overall stability of the screw 33 when it rotates.

[0048] Furthermore, a groove 341 is provided on the outer surface of the sleeve 34, and a movable plate 35 is provided at the end of the screw 33. A slider 351 is provided on the outer surface of the movable plate 35, and the outer surface of the slider 351 is slidably connected to the inner wall of the groove 341.

[0049] Specifically, when the screw 33 moves, it synchronously drives the movable plate 35 at its end to move. At the same time, the slider 351 and the groove 341 on the movable plate 35 limit the movement, thereby preventing the movable plate 35 from shifting.

[0050] Furthermore, the lower end of the movable plate 35 has multiple sets of slots 36, which are evenly distributed at the end of the movable plate 35. An adjusting rod 38 is slidably installed on the inner wall of the slot 36. The end of the adjusting rod 38 has a movable groove 381, and a clamping plate 39 is provided at the end of the adjusting rod 38. The upper end of the outer surface of the adjusting rod 38 is tapered, and a locking rod 382 is provided on the inner wall of the movable groove 381. The end of the locking rod 382 is connected to the inner wall of the slot 36.

[0051] Specifically, when the movable plate 35 moves, it drives the adjusting rod 38 to move in conjunction with the slot 36, while the clamping plate 39 at the end of the adjusting rod 38 limits the outer surface of the aluminum foil. The adjusting rod 38 is further limited by the snap-fit ​​rod 382 set on the inner wall of the slot 36, thereby keeping the adjusting rod 38 stable.

[0052] Furthermore, a positioning rod 37 is provided at the middle position of the lower end of the movable plate 35, and a pressing block 342 is provided on the inner wall of the sleeve 34. A stop block 343 is provided on the inner wall of the sleeve 34 below the pressing block 342. The outer surfaces of the pressing block 342 and the stop block 343 are slidably connected to the outer surface of the adjusting rod 38. The cross-section of the pressing block 342 and the stop block 343 is triangular, and the end of the positioning rod 37 is inclined.

[0053] Specifically, when the adjusting rod 38 moves, it is constrained by the pressing block 342 and the stop block 343 set on the inner wall of the sleeve 34. When the adjusting rod 38 moves, the stop block 343 drives the end of the adjusting rod 38 to move towards the middle, thereby clamping the aluminum foil and making it easier to stretch the aluminum foil, so that the surface of the aluminum foil is in a stable state.

[0054] Furthermore, the flipping assembly 2 includes a base plate 21 connected to the base 1. A driving member 22 is provided at one end of the base plate 21, and the output end of the driving member 22 extends through and to the other end of the base plate 21. A first support plate 23 is provided at the output end of the driving member 22, and a second support plate 24 is rotatably mounted at the end of the first support plate 23 away from the driving member 22.

[0055] In this embodiment, the driving component 22 is a device with power output such as a motor, and is connected to an external control device. When the driving component 22 is started, it synchronously drives the first support plate 23 set at its output end to rotate. Since the end of the first support plate 23 is rotatably connected to the end of the second support plate 24, it drives the second support plate 24 to move.

[0056] Furthermore, a fixing block 25 is rotatably mounted on the end of the second support plate 24, and a round rod 26 is symmetrically arranged on the end of the fixing block 25. A positioning block 27 is symmetrically arranged on the upper end of the base plate 21. The upper end of the positioning block 27 is arc-shaped, and the upper end of the positioning block 27 is in contact with the outer surface of the round rod 26.

[0057] Specifically, the first support plate 23 and the second support plate 24 drive the fixed block 25 to move, and simultaneously drive the round rod 26 set on the fixed block 25 to move, wherein the positioning block 27 supports the round rod 26.

[0058] Furthermore, a support plate 251 is provided at the end of the fixed block 25 away from the second support plate 24, and an adjustment plate 252 is provided at the upper end of the support plate 251.

[0059] Specifically, the aluminum foil is supported by the support plate 251 and the adjustment plate 252, thereby preventing the middle part of the aluminum foil from sinking during the test, which would affect the overall test results.

[0060] Furthermore, a snap-fit ​​plate 16 is provided at the upper end of the movable block 15. The snap-fit ​​plate 16 has an L-shaped cross-section, and the inner wall of the snap-fit ​​plate 16 is slidably connected to the outer surface of the round rod 26.

[0061] Specifically, when the moving block 15 moves, it synchronously drives the snap-fit ​​plate 16 to move, thereby causing the snap-fit ​​plate 16 to separate from the outer surface of the round rod 26. When the first support plate 23 and the second support plate 24 move, they drive the fixing block 25 to rotate around the round rod 26 at the other end, thereby inspecting the other side of the aluminum foil.

[0062] The control device can choose a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption. Example

[0063] A method for detecting the flatness of aluminum foil, using an aluminum foil flatness detection device as described in any of the embodiments in Example 1, includes the following steps:

[0064] S1. First, place the object to be tested on the testing platform, and use the stretching component 3 to clamp the four corners of the aluminum foil and slowly stretch it outward to reduce wrinkles on the outer surface of the aluminum foil.

[0065] S2. The support columns 11 and cleaning components 12 on both sides of the base 1 are used to clean the outer surface of the stretched aluminum foil to reduce the impact of particulate matter on the test results.

[0066] S3. After the inspection on one side is completed, the aluminum foil is transferred to another inspection platform by the flipping component 2, and the aluminum foil is flipped to inspect the aluminum foil on the other side.

[0067] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
