Description

Technical Field

[0001] The utility model relates to the technical field of thickness measurement of lithium battery electrodes, and particularly relates to a ray-laser combined thickness gauge. Background Art

[0002] Thickness gauges are widely used in the on-line detection of the thickness of materials such as paper, wood boards, steel plates, conveyor belts, rubber sheets, battery electrodes, etc. due to their advantages of high safety, excellent measurement accuracy, and wide measurement range. In the production process of lithium batteries, it is necessary to control the consistency of the batteries, and the consistency of the surface density of the coated electrodes is a key factor affecting this process. Therefore, it is necessary to detect the surface density of the electrodes in real time during the coating process. The methods for detecting the surface density of the electrodes are divided into contact manual measurement and non-contact instrument measurement. Among them, the manual contact measurement method has poor accuracy and is not convenient for real-time detection. The non-contact instrument measurement method uses a thickness gauge to measure the coating and rolling thickness of the electrodes on-line. In the on-line measurement process of the coating thickness of the electrodes, after the coating drying process and the rolling process of the electrodes are completed, the ray component is used to measure the thickness of the rolled electrodes. Ray thickness measurement mainly uses rays to penetrate the coating to measure the surface density value. The transmitter emits rays towards the electrode. When the rays pass through the material, attenuation occurs. As the surface density increases, the attenuation of the rays increases. Then, the attenuation degree of the rays after passing through the electrode is measured, and thus the surface density value of the electrode is measured.

[0003] Affected by the coating process, after the coating drying of the electrode is completed, the thickness at the boundaries on both sides of the coating of the electrode shows a gradually decreasing trend, which leads to the formation of the so-called thinning area of the electrode coating. However, since the ray component feeds back the average thickness of a certain specific area during the process of obtaining the coating thickness information, it means that when the ray component measures the thinning area of the coated electrode, the ray component cannot provide the accurate thickness data of a specific point. When the ray component measures the thinning area of the electrode coating, it cannot accurately feedback the specific value of a specific point in the thinning area or the decreasing trend of the thickness of the thinning area deduced from the specific values fed back by several specific points, nor can it obtain the thickness data of multiple specific points to calculate the thickness change of the thinning area. Therefore, the data feedback of the ray thickness measurement component when measuring the thinning area of the coated electrode is not sufficient to meet the accuracy requirements. In order to measure the thinning area of the coated electrode on-line, the thickness gauge needs to be equipped with a laser component, so that the laser component can be used to measure the thinning area of the coated electrode, and the measurement data of the laser component and the measurement data of the ray component are mutually corrected to improve the reliability of the finally obtained thickness feedback data.

[0004] In order to use a thickness measuring device that combines laser and ray, it is necessary to assemble multiple rollers on the thickness measuring device to flatten and turn the conveyed battery electrode sheet. During the process of assembling the rollers, it is necessary to first assemble bearing seats on both sides of the rollers, and then use screws to assemble and fix the bearing seats to the thickness measuring device. However, during the process of installing the bearing seats to the thickness measuring device with screws, the bearing seats may move on the screws, resulting in the rollers being assembled obliquely on the thickness measuring device, thereby affecting the accuracy of measuring the thickness of the electrode sheet by laser and ray. Therefore, there are improvements in the solution of assembling the rollers on the thickness measuring device to improve the assembly accuracy of the rollers, thereby reducing the error of measuring the thickness of the electrode sheet by laser and ray.

Then, the two second bolts 27 are respectively placed in the U-shaped grooves 30 of the two first brackets 26, and the position of the bubble of the bubble level 29 is observed to judge whether the two second roller shafts 15 are kept at the same height.

[0026] Please refer to again Figure 6 , a cross groove 32 and a perforation are respectively formed in the middle part of the fixing rod 28.

[0031] Before using this product, the first roller 7 and the second roller 15 need to be assembled. The specific assembly method is as follows: As Figures 1 to 6 shown, first, a plurality of setscrew seats 10 are respectively installed on the idler bracket 6, and first setscrews 11 are screwed on the plurality of setscrew seats 10. The adapter block 9 is placed between the adjacent upper and lower first setscrews 11.

Repeat the above steps to install multiple setscrew seats 10 between the adjacent upper and lower first setscrews 11 in turn; then, check whether the adapter blocks 9 on both sides of the idler bracket 6 are at the same height. If the adapter blocks 9 on both sides of the idler bracket 6 are not at the same height, adjust the first setscrews 11 again to make the adapter blocks 9 on both sides of the idler bracket 6 at the same height. After adjusting the adapter blocks 9 on both sides of the idler bracket 6 to be at the same height, use screws to fix the adapter blocks 9 to the idler bracket 6, and then install first setscrew plates 12 on both sides of the adapter blocks 9, and screw second setscrews 13 on the first setscrew plates 12.

[0032] Then, place the first bearing block 8 between the two limiting bars 14. By turning the second setscrew 13, press the first bearing block 8 tightly between the adjacent second setscrews 13 on the left and right. Repeat the process to sequentially install multiple first bearing blocks 8 on the setscrew seat 10. Then, check whether the central axes of the first bearing blocks 8 on both sides of the idler support 6 are on the same straight line. If the central axes of the first bearing blocks 8 on both sides of the idler support 6 are not on the same straight line, adjust the second setscrew 13 again to make the central axes of the first bearing blocks 8 on both sides of the idler support 6 on the same straight line. After adjusting the central axes of the first bearing blocks 8 on both sides of the idler support 6 to be on the same straight line, use screws to fix the first bearing block 8 to the adapter block 9, and then rotatably install the first roller shaft 7 on the first bearing block 8 to complete the assembly of the first roller shaft 7.

[0033] Then, first install the second bearing block 16 onto the adapter plate 17, and respectively sleeved the protective plate 19, the adapter plate 17, and the fixing plate 18 onto the first bolt 23.

By screwing the third setscrew 25 into the second setscrew plate 24, make the third setscrew 25 abut against the bottom surface of the adapter plate 17. Then, install the two first brackets 26 onto the second bearing blocks 16 provided at one ends of the two second roller shafts 15 respectively. Then, place the two bolts 27 into the U-shaped grooves 30 of the second bearing blocks 16 respectively, and observe the position of the bubble of the bubble level 29 to determine whether the two second roller shafts 15 are at the same height. If the two second roller shafts 15 are not at the same height, adjust them to be at the same height. By screwing in the first bolt 23, press and fix the protective plate 19, the adapter plate 17, and the fixing plate 18 onto the idler support 6, and then rotatably install the second roller shaft 15 onto the second bearing block 8 to complete the assembly of the second roller shaft 15.

[0034] It should be noted that in order to control the vertical passing of the pole piece between the first laser rangefinder and the second laser rangefinder of the laser assembly 5, it is necessary to adjust the roller shaft assemblies respectively arranged above and below the laser assembly 5 with the aid of a straightening device. First, install the support plate 37 on the first bearing block 8 of the roller shaft assembly above the laser assembly 5. Sleeve one of the fourth bolts 38 into the socket 40, and then respectively screw the two fourth bolts 38 onto the support rod 39, and adjust the position of the one fourth bolt 38 sleeved in the socket 40 with reference to the third scale layer 41. Then, adjust the first bearing block 8 of the roller shaft assembly below the laser assembly 5 to contact with the other fourth bolt 38 by the above method, so as to control the vertical passing of the pole piece between the first laser rangefinder and the second laser rangefinder of the laser assembly 5.

[0035] Through the embodiments, by means of the set setscrew seat 10 and the first setscrew 11, the adapter block 9 is clamped on the idler bracket 6. By adjusting the protruding amount of the first setscrew 11 in the setscrew seat 10, the vertical position of the adapter block 9 can be conveniently adjusted; similarly, by adjusting the protruding amount of the second setscrew 13 in the first setscrew plate 12, the horizontal position of the first bearing block 8 can be conveniently adjusted, and then the positions of both ends of the first roller shaft 7 are adjusted.
