Description

Technical Field

[0001] The invention relates to the technical field of laser thickness measurement, in particular to a composite aluminum foil current collector coating thickness detection device. Background Art

[0002] The composite aluminum foil current collector is a new type of lithium battery material. A polymer material support layer is used between the two metal conductive layers to improve the safety, energy density and other performance of the battery. In the preparation process of the composite aluminum foil current collector, the thickness of the composite aluminum foil current collector is extremely critical, which is directly related to the performance of the aluminum foil. The current composite aluminum foil current collector coating thickness detection device usually requires manual sampling and weighing to test the thickness, which is not convenient for non-destructive testing on the production line. At the same time, it will cause the production line to stagnate when the sample is taken, which is not convenient for automatic detection without stopping the machine. The traditional single-piece aluminum foil testing method has a single sampling position, and the multi-piece thickness measurement method has a great influence on the thickness of the aluminum foil by the flatness of the aluminum foil, which reduces the detection accuracy and the data is not accurate enough. At the same time, it is not convenient to control the measurement position. If the aluminum foil welding point or the position with defects is measured, it will also affect the measurement accuracy.

[0018] The use of a compact bulge test piece in conjunction with a pressing piece can prevent the problem of poor thickness accuracy due to poor surface flatness of the aluminum foil and poor tightness of the aluminum foil when winding, which causes the aluminum foil detection position after winding to still have a gap between the aluminum foils after the pressing frame moves down to fit the aluminum foil. This ensures the flatness of the multi-layer aluminum foil during measurement and the accuracy of the sampling position. At the same time, it can reduce the interference caused by wear on the bottom of the bulge test shell. The bulge test shell can be used to perform inspections before each thickness measurement to ensure the accuracy of the recorded data. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Example 1: Please refer to Figures 1 to 11 As shown:

The real bulge test piece 5 is used to test the winding effect of the composite aluminum foil; a negative pressure piece 6 is installed on the detection conveyor 1; two stuck test pieces 7 are installed at the bottom of the negative pressure piece 6; the stuck test piece 7 is used to test the surface smoothness of the composite aluminum foil; the detection conveyor 1 includes: a conveyor mounting plate 101 and a lifting slider 102, and two lifting sliders 102 are slidably installed on the conveyor mounting plate 101; two rows of through holes are opened on the conveyor mounting plate 101, and the two rows of through holes at the bottom of the conveyor mounting plate 101 are used to pass bolts to be installed on the composite aluminum foil production line.

[0034] The detection conveying member 1 further includes: a floating roller 103 and a fixed roller 104, and the two lifting sliders 102 are respectively rotatably mounted with the floating rollers 103; the conveying mounting plate 101 is rotatably mounted with two fixed rollers 104; the driving winding member 2 includes: a driving motor 201, a rotating disk 202, a winding roller 203, a supporting disk 204 and an indicator light 205, and the driving motor 201 is fixedly mounted on the conveying mounting plate 101; the output shaft of the driving motor 201 passes through the conveying mounting plate 101; the output shaft of the driving motor 201 is fixedly mounted with a rotating disk 202; four winding rollers 203 are rotatably mounted on the rotating disk 202; the rotating disk 20 2 is fixedly mounted with a support plate 204; the top surface of the support plate 204 is tangent to the two winding rollers 203 on the same side; an indicator light 205 is fixedly mounted on the support plate 204; the laser thickness measuring part 3 includes: a support frame 301, a thickness laser distance meter 302 and a deviation warning light 303, the support frame 301 is fixedly mounted on the side of the conveying mounting plate 101 by two bolts; a thickness laser distance meter 302 is fixedly mounted on the support frame 301; the thickness laser distance meter 302 is used to laser measure the thickness of the composite aluminum foil; a deviation warning light 303 is fixedly mounted on the front side of the support frame 301; the thickness laser distance meter 302 is located above the support plate 204, and uses laser The thickness measuring part 3 can realize online detection, and cooperate with the driving winding part 2 to realize one-time winding of aluminum foil for multi-layer detection, reduce the error caused by local sampling, and make the result more accurate. It also helps to eliminate the error of laser thickness measurement of thinner aluminum foil. Cooperating with the detection conveying part 1, there is no need to stop sampling, and sampling and winding detection can be carried out during the aluminum foil conveying process without affecting the normal winding and conveying of the aluminum foil. The floating roller 103 can realize lifting and floating adaptation, and the structure is more reasonable, avoiding breaking of the aluminum foil, and is more practical. It can ensure multi-layer thickness measurement while ensuring online detection, and can realize non-destructive thickness measurement, reduce the scrap rate, and convey the bottom of the installation plate 101. The two rows of through holes are used to pass bolts to be installed on the composite aluminum foil production line. When the aluminum foil is rolled up and its length is shortened, the floating roller 103 can be pulled to drive the lifting slider 102 to rise for adaptation. Similarly, if one end has an aluminum foil rolling structure, the floating roller 103 will also adapt and rise. The aluminum foil will not be directly torn off, and subsequent inspections can be carried out quickly. The weight of the floating roller 103 can be used to reserve a buffer length for the aluminum foil, thereby improving the safety of aluminum foil transportation and measurement. The length of the distance to the bulge test shell 501 is measured by the thickness laser rangefinder 302. Because the bottom of the bulge test shell 501 will fit the aluminum foil, the thickness of the aluminum foil can be reflected more stably.

[0035] The pressing member 4 includes: a pressing frame 401, a pressing electromagnet 402, a test block 403, an elastic rubber strip 4031 and an electric wire 4032. The pressing frame 401 is slidably mounted on the support frame 301; a pressing electromagnet 402 is fixedly mounted on the pressing frame 401; the pressing electromagnet 402 is used to magnetically attract the support frame 301; a spring is provided between the pressing frame 401 and the support frame 301, and the spring between the pressing frame 401 and the support frame 301 is located on the outside of the pressing electromagnet 402; a test block 403 is fixedly mounted on the pressing frame 401; an elastic rubber strip 4031 is fixedly mounted on the inner side of the test block 403, and the elastic A power connection wire 4032 is fixedly installed on the side of the rubber strip 4031; the compact bulge test piece 5 includes: a bulge test shell 501, a closed bellows 502 and a tension spring 503, and the bulge test shell 501 is fixedly installed with a closed bellows 502; the bulge test shell 501 is slidably installed on the support frame 301; the top of the closed bellows 502 is fixedly installed at the bottom of the thickness laser rangefinder 302; the outer side of the bulge test shell 501 is sleeved with a tension spring 503; the two ends of the tension spring 503 are connected between the bulge test shell 501 and the pressing frame 401; the bulge test shell 501 is used to fit the aluminum foil; the compact bulge test piece 5 also includes: a power connection ring 50 4. The outer side of the bulge test shell 501 is sleeved with a connecting ring 504, and the connecting ring 504 fits the connecting wire 4032; the connecting ring 504, the connecting wire 4032 and the deviation warning light 303 are connected in series with the power supply, and the compact bulge test piece 5 is used in conjunction with the pressing piece 4, which can prevent the problem of poor surface flatness of the aluminum foil and poor tightness of the aluminum foil when winding, resulting in the aluminum foil detection position after the pressing frame 401 moves down to fit the aluminum foil. There is still a gap between the aluminum foils, resulting in the thickness accuracy not meeting the standard. Ensure the flatness of the multi-layer aluminum foil during measurement and ensure the accuracy of the sampling position. At the same time, it can reduce the problem of poor surface flatness of the aluminum foil and poor tightness of the aluminum foil when winding. The interference caused by wear takes advantage of the problem of height difference in the detection area when the winding tightness is poor or the aluminum foil is uneven. The bulge test shell 501 can be used for detection before each thickness measurement to ensure the accuracy of the recorded data. The bulge test shell 501 will fit the aluminum foil. Once the aluminum foil below the bulge test shell 501 and the pressing frame 401 are no longer in the same plane, with the pulling of the tension spring 503, the bulge test shell 501 is no longer flush with the pressing frame 401, and the corresponding power connection ring 504 is misaligned with the power connection wire 4032 and no longer fits. The deviation warning light 303 will also go out to warn, and the thickness data at this time is not used as a reference.

[0036] Among them, the negative pressure part 6 includes: a negative pressure box 601, a fitting rubber ring 6011, and a negative pressure fan 602. The negative pressure box 601 is fixedly installed on the side of the conveying mounting plate 101; a fitting rubber ring 6011 is fixedly installed on the inner side of the negative pressure box 601; the fitting rubber ring 6011 is grooved in the middle; the two fitting rubber rings 6011 are used to fit the two sides of the aluminum foil; the negative pressure box 601 is a hollow structure; a negative pressure fan 602 is fixedly installed on the side of the negative pressure box 601; the negative pressure fan 602 is used to suck wind; the negative pressure part 6 can be used to perform cleaning work by negative pressure, reducing the impact of the attachments on the surface of the aluminum foil on subsequent tests. The structure is simple and reasonable, and the negative pressure cleaning method can reduce wear.

[0037] Embodiment 2, on the basis of embodiment 1, the stuck test piece 7 comprises: a stuck installation slot block 701, a pressing slider 702 and a delay switch 703, two stuck installation slot blocks 701 are fixedly installed at the bottom of the negative pressure box 601; the structures on the two stuck installation slot blocks 701 are the same; a pressing slider 702 is slidably installed on the stuck installation slot block 701; a delay switch 703 is fixedly installed on the pressing slider 702, and the end of the delay switch 703 is attached to the inner side of the stuck installation slot block 701; the stuck installation slot block 701 is electrically connected to the indicator light 205; the stuck test piece 7 also comprises: a V-shaped spring piece 704, a bonding spring piece 705 and a bonding fiber cloth 706, two V-shaped spring pieces 704 are fixedly installed on the pressing slider 702; the ends of the two V-shaped spring pieces 704 are respectively connected to the inner side of the stuck installation slot block 701; a bonding spring piece 705 is fixedly installed on the bottom of the pressing slider 702; the bonding spring piece 705 is attached to the inner side of the stuck installation slot block 701 ... A bonding fiber cloth 706 is fixedly installed at the bottom of the spring piece 705, and the bonding fiber cloth 706 is used to bond to the surface of the aluminum foil. The card test piece 7 is used to control the measurement position and directly prompt the staff. It can be used to prompt to avoid the aluminum foil welding points or defective positions to ensure the test accuracy. At the same time, it can avoid the welding points or defective positions from damaging the adjacent aluminum foil during winding or thickness measurement, and the defective positions from being broken, which can reduce the defective rate and ensure the accuracy of the thickness measurement position. During the aluminum foil transportation process, as the negative pressure piece 6 is cleaned, if there are still adhered impurities, burrs or laser welding points on the surface of the aluminum foil, the aluminum foil will rub against the bonding fiber cloth 706, and then pull the bonding fiber cloth 706 downward, so that the indicator light 205 can be controlled to light up to prompt that thickness measurement cannot be performed during this time period, and it also plays a role in assisting the staff to perform quality inspection on this section of the aluminum foil.

[0038] The working principle of this embodiment is: first, place the aluminum foil as shown in the attached Figure 1The positions are respectively attached to the floating roller 103, the fixed roller 104 and the winding roller 203. At this time, as the aluminum foil is transported, if the thickness of the aluminum foil needs to be detected, the driving motor 201 can be directly controlled to drive the four winding rollers 203 to rotate, so that the aluminum foil is sleeved on the outside of the four winding rollers 203. The number of turns can be adjusted according to the needs. In this process, because the aluminum foil is rolled up and the length is shortened, the floating roller 103 can be pulled to drive the lifting slider 102 to rise for adaptation. Similarly, if one end has an aluminum foil winding structure, the floating roller 103 will also adapt and rise, and the aluminum foil will not be directly torn off, and subsequent detection can be carried out quickly. The floating roller 103 can be used to roll the aluminum foil around the outside of the four winding rollers 203. In order to leave a buffer length for the aluminum foil, when the four winding rollers 203 have finished winding the aluminum foil, the support plate 204 is limited at the bottom. At this time, the length of the distance to the bulge test shell 501 can be measured by the thickness laser rangefinder 302, because the bottom of the bulge test shell 501 will fit the aluminum foil, so that the thickness of the aluminum foil can be more stably reflected. Before the thickness measurement work is performed by the thickness laser rangefinder 302, the support frame 301 is magnetically attracted by the pressing electromagnet 402, and the aluminum foil can be pressed by the pressing frame 401. At this time, if the compactness of the aluminum foil does not meet the standard, when the aluminum foil is pressed down, the aluminum foil is a composite material, and the aluminum foil below the bulge test shell 501 lacks When the pressing frame 401 is pressed, the bulge test shell 501 will fit the aluminum foil. Once the bottom of the bulge test shell 501 and the aluminum foil under the pressing frame 401 are no longer in the same plane, with the pulling of the tension spring 503, the bulge test shell 501 is no longer flush with the pressing frame 401, and the corresponding power connection ring 504 and the power connection wire 4032 are misaligned and no longer fit. The deviation warning light 303 will also go out to warn. The thickness data at this time is not used as a reference. Similarly, if the bottom of the bulge test shell 501 is greatly worn due to long-term use, the power connection ring 504 and the power connection wire 4032 will also be misaligned, which can also avoid errors caused by wear and tear. To ensure the multi-layer aluminum foil is fitted together during the test and to ensure accuracy, the negative pressure fan 602 can be used for real-time suction, and the negative pressure box 601 can be used to cover and buckle the two sides of the aluminum foil for cleaning. As the negative pressure part 6 completes the cleaning, if there are still adhered impurities, burrs or laser welding points on the surface of the aluminum foil, the aluminum foil will rub against the fitted fiber cloth 706, and then pull the fitted fiber cloth 706 downward, driving the downward pressure slider 702 to move downward and lengthen the V-shaped spring piece 704. At this time, the delay switch 703 is also driven downward, and no longer squeezes and blocks the inner side of the mounting slot block 701, so that the indicator light 205 can be controlled to light up to indicate that thickness measurement cannot be performed during this time period.
