Description

Technical Field

[0001] The utility model relates to the field of laser thickness gauges, and particularly relates to an adjusting slide table of a laser thickness gauge. Background Technique

[0002] The coating thickness of the lithium-ion battery electrode plate is an important parameter for evaluating the working efficiency and stability of the lithium battery. The real-time high-precision measurement of the coating thickness of the lithium-ion battery electrode plate is the premise for realizing its control. The on-line measurement of the thickness is mainly based on non-contact measurement methods, including ultrasonic measurement method, ray measurement method, optical measurement method, capacitive measurement method, etc. The method of using non-contact laser to measure the thickness is one of the principles adopted in the design of the thickness gauge. The instrument for using non-contact laser to measure the thickness is a laser thickness gauge. The laser displacement sensor is one of the most important components of the thickness measuring device, and its performance directly determines the index of the thickness measuring device. The main indexes for measuring the laser displacement sensor are measurement accuracy, measurement range, resolution, and system stability.

[0003] Before measuring the sample with a non-contact laser thickness gauge, it is necessary to first adjust the distance between the laser displacement sensors, and then adjust the coaxiality of the two laser displacement sensors until the optical axes released by the two laser displacement sensors are aligned. The sample to be measured is placed in the effective measurement areas of the two displacement sensors. The thickness of the sample is calculated based on the distance between the zero positions measured by the two displacement sensors and the values fed back by the two displacement sensors.

[0004] In the prior art, after adjusting the spacing of the laser displacement sensor on the Z-axis, during the process of adjusting the coaxiality of the two laser displacement sensors, the X-axis displacement adjusting device and the Y-axis displacement adjusting device are used to position the X-axis position and the Y-axis position of the corresponding laser displacement sensor respectively. The X-axis displacement adjusting device and the Y-axis displacement adjusting device are both adjusted by the cooperation of the limit chute and the limit slider. There is an installation gap between the limit slider and the limit slide rail. After adjusting the displacement of the corresponding laser displacement sensor by using the X-axis displacement adjusting device or the Y-axis displacement adjusting device, it is still necessary to fix the relative positions of the corresponding limit slider and the limit slide rail so that the corresponding laser displacement sensor can work stably at the adjusted position. Due to the installation gap between the limit slider and the limit slide rail, during the process of fixing the limit slider and the limit slide rail, the relative position of the limit slider on the limit slide rail will change slightly due to the installation gap between the limit slider and the limit slide rail, resulting in a difference in the coaxiality of the two laser displacement sensors. For a laser thickness gauge that requires a high numerical feedback accuracy, it is necessary to repeatedly adjust the X-axis displacement adjusting device or the Y-axis displacement adjusting device many times to reach the preset position, and the operation is not convenient. Therefore, there is room for improvement in the prior art. In the actual situation where there is an installation gap between the limit slider and the limit slide rail, during the process of fixing the limit slider and the limit slide rail, the offset of the relative position of the limit slider is reduced, thereby reducing the adjustment times of the X-axis displacement adjusting device or the Y-axis displacement adjusting device, and further improving the convenience of operation and the promotion degree of the product.

[0022] As Figures 1 to 6 shown, an adjustment slide table of a laser thickness gauge includes a bottom plate 1. One side of the bottom plate 1 is provided with a top plate 2. A first adjustment plate 3 is arranged between the top plate 2 and the bottom plate 1. A second adjustment plate 4 is arranged between the first adjustment plate 3 and the bottom plate 1. One end of the top plate 2 facing the first adjustment plate 3 is provided with a first sliding groove 5. A first sliding block 6 is arranged in the first sliding groove 5. The first sliding block 6 is a block structure capable of sliding along the extending direction of the first sliding groove 5. The first sliding block 6 is connected to the first adjustment plate 3. One end of the first adjustment plate 3 facing the second adjustment plate 4 is provided with a second sliding groove 7. A second sliding block 8 is arranged in the second sliding groove 7. The second sliding block 8 is a block structure capable of sliding along the extending direction of the second sliding groove 7. The second sliding block 8 is connected to the second adjustment plate 4. The second sliding groove 7 is perpendicular to the first sliding groove 5. The bottom plate 1, the top plate 2 and the first adjustment plate 3 are provided with a distance measuring instrument passing groove 9. A laser distance measuring instrument 10 is arranged on the second adjustment plate 4 in the distance measuring instrument passing groove 9. One end of the second adjustment plate 4 facing the bottom plate 1 is provided with a pressing mechanism. The pressing mechanism includes a first limiting groove 11 opened at one end of the second adjustment plate 4 close to the bottom plate 1 along the direction from close to the bottom plate 1 to away from the bottom plate 1 and a spring 12 arranged in the first limiting groove 11. One end of the top plate 2 facing the top plate 2 is provided with a connecting column 28. A third fixing bolt 29 is arranged on the connecting column 28 and the bottom plate 1. A clamping sleeve 16 is arranged on the second adjustment plate 4. The laser distance measuring instrument 10 is installed on the clamping sleeve 16.

[0023] The number of the pressing mechanisms is several. The several pressing mechanisms are evenly distributed in a star shape outside the central axis of the distance measuring instrument passing groove 9; thus, it is convenient to use the several constant pressure mechanisms to generate uniform stress towards the top plate 2, so that the second sliding groove 7 and the second sliding block 8 are in fit and the first sliding groove 5 and the first sliding block 6 are in fit.

[0024] A first displacement adjusting device is provided on the bottom plate 1, and a second displacement adjusting device is provided on the top plate 2. Both the second displacement adjusting device and the first displacement adjusting device include a U-shaped fixing plate 13, an adjusting bolt 14, and a circular second limiting groove 15 formed on the adjusting bolt 14 inside the fixing plate 13. The fixing plate 13 is movably connected to the second limiting groove 15. The adjusting bolt 14 of the first displacement adjusting device is threadedly connected to the second adjusting plate 4, and the adjusting bolt 14 of the first displacement adjusting device is parallel to the second sliding groove 7. The adjusting bolt 14 of the second displacement adjusting device is threadedly connected to the first adjusting plate 3, and the adjusting bolt 14 of the second displacement adjusting device is parallel to the first sliding groove 5. The fixing plate 13 of the first displacement adjusting device is connected to the bottom plate 1, and the fixing plate 13 of the second displacement adjusting device is connected to the top plate 2. Thus, it is convenient to use the first displacement adjusting device to adjust the relative position of the second adjusting plate 4 and use the second displacement adjusting device to adjust the relative position of the first adjusting plate 3.

[0025] The pressing mechanism further includes a sleeve 17 inside the spring 12, a telescopic rod 18 provided inside the sleeve 17, a first mounting sleeve 19 provided at one end of the telescopic rod 18 away from the sleeve 17, a second mounting sleeve 20 provided at one end of the first mounting sleeve 19 away from the telescopic rod 18, and balls 21 provided on the second mounting sleeve 20 and the first mounting sleeve 19. The inner cavity of the first limiting groove 11 adopts a cylindrical groove structure. The shape of the second mounting sleeve 20 or the shape of the first mounting sleeve 19 matches the inner cavity of the first limiting groove 11. The balls 21 adopt a spherical structure capable of rotating around the center of the balls 21. The sleeve 17 is connected to the first limiting groove 11. Third limiting grooves 22 are formed on the second mounting sleeve 20 and the first mounting sleeve 19, and the balls 21 are movably connected to the third limiting grooves 22. The second mounting sleeve 20 and the first mounting sleeve 19 are threadedly connected. Installing the sleeve 17 and the telescopic rod 18 facilitates limiting the movement direction of the second mounting sleeve 20 and the first mounting sleeve 19, thereby indirectly limiting the deformation direction of the spring 12. And further, the balls 21 are installed on the second mounting sleeve 20 and the first mounting sleeve 19, so that the contact between the pressing mechanism and the bottom plate 1 is changed from sliding friction to rolling friction, reducing the friction force between the pressing mechanism and the bottom plate 1 and reducing the resistance received by the second adjusting plate 4 during the moving process.

[0026] Furthermore, since the second adjusting plate 4 is connected to the second slider 8, and the second slider 8 is a block structure capable of sliding along the extending direction of the second chute 7, the displacement direction of the second adjusting plate 4 is the same as that of the second slider 8. Therefore, the number of the pressing mechanisms of this product is four, and the four pressing mechanisms are respectively located on both sides of the laser rangefinder 10. The number of the pressing mechanisms on each side of the laser rangefinder 10 is two. Third chutes 23 are respectively formed at one ends of the bottom plates 1 on both sides of the laser rangefinder 10 facing the second adjusting plate 4. The number of the third chutes 23 is two. The balls 21 in the two pressing mechanisms on one side of the laser rangefinder 10 are all movably connected to the third chute 23 on the corresponding side of the laser rangefinder 10, and the third chute 23 is parallel to the second chute 7. The movement direction of the pressing mechanism is further defined by the third chute 23.

[0027] Fourth chutes 24 are respectively arranged on the second adjusting plates 4 on both sides of the laser rangefinder 10. A plurality of the fourth chutes 24 are all parallel to the second chute 7. A first fixing bolt 25 is respectively arranged on each of the fourth chutes 24 and the first adjusting plate 3; thus, it is convenient to fix the second adjusting plate 4 and the first adjusting plate 3 by using the first fixing bolt 25; Fifth chutes 26 are respectively arranged on the first adjusting plates 3 on both sides of the fourth chutes 24. A plurality of the fifth chutes 26 are all parallel to the first chute 5. A second fixing bolt 27 is respectively arranged on each of the fifth chutes 26 and the top plate 2, so as to facilitate fixing the relative positions of the top plate 2 and the first adjusting plate 3 by using the second fixing bolt 27.

[0028] The usage method of this product is as follows. As Figures 1 to 6 shown, after installing two of this product into the preset installation positions in the laser thickness gauge respectively, then adjust the coaxiality of the two laser rangefinders 10, which specifically includes the following steps:

[0029] First, loosen the first fixing bolt 25 and the second fixing bolt 27 corresponding to the laser rangefinder 10 in one of this product to fix the relative position of the laser rangefinder 10. Then, adjust the adjusting bolt 14 of the first displacement adjusting device of the other product under the limitation of the second chute 7 and the second slider 8, so as to adjust the relative position of the second adjusting plate 4 and further adjust the position of the laser rangefinder 10 in this product in the X-axis direction until the light rays emitted by the two laser rangefinders 10 are in the same plane in the X-axis direction; Then, adjust the adjusting bolt 14 in the second displacement adjusting device of this product to adjust the relative position of the first adjusting plate 3. The first adjusting plate 3 drives the second adjusting plate 4 to move synchronously under the limitation of the first chute 5 and the first slider 6 and the limitation of the second slider 8 and the second chute 7, so as to drive the laser rangefinder to move in the Y-axis direction until the light rays released by the two laser rangefinders 10 are on the same axis.

[0030] During the process of adjusting the positions of the corresponding laser rangefinders 10 by using the first displacement adjusting device and the second displacement adjusting device, the springs 12 in several of the pressing mechanisms in this product are always compressed, so that the first sliding groove 5 and the first sliding block 6 are in contact with each other, and the second sliding block 8 and the second sliding groove 7 are in contact with each other. Furthermore, the gaps between the top plate 2 and the first adjusting plate 3 and between the first adjusting plate 3 and the second adjusting plate 4 are reduced. When the first fixing bolt 25 is tightened, the displacement amount between the first adjusting plate 3 and the second adjusting plate 4 is reduced, thereby reducing the displacement deviation caused by the position offset during the fixing of the first adjusting plate 3 and the second adjusting plate 4. Similarly, during the process of the second fixing bolt 27, the displacement amount between the top plate 2 and the first adjusting plate 3 is also reduced, thereby reducing the displacement deviation caused by the position offset during the fixing of the top plate 2 and the first adjusting plate 3.

[0031] Through this embodiment, the stress is continuously provided by the compression of the spring 12 in the pressing mechanism, so that the gap between the first sliding groove 5 and the first sliding block 6 and the gap between the first adjusting plate 3 and the second adjusting plate 4 are reduced. Furthermore, the displacement deviation between the first adjusting plate 3 and the second adjusting plate 4 caused by tightening the first fixing bolt 25 when fixing the laser rangefinder 10 and the displacement deviation between the top plate 2 and the first adjusting plate 3 caused by tightening the second fixing bolt 27 are reduced.

[0032] The above-described embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present invention patent should be included in the scope of the patent application of the present invention.
