[0020] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0021] As described in the background art, existing measuring devices are unable to determine whether the thickness of the ceramic plate is uniform, resulting in errors in the measurement results.

[0022] In order to solve this technical problem, the present invention provides a ceramic substrate thickness detection device, which is used for thickness detection.

[0023] Specifically, please refer to Figure 1-Figure 7 As shown, the ceramic substrate thickness detection device specifically includes: a base 1, a support frame 101 slidably arranged on the base 1, a laser rangefinder 102 arranged on the support frame 101, and an adjustment mechanism 2 arranged on the support frame 101. In the prior art, the laser rangefinder 102 is used to measure the thickness of the ceramic substrate and determine whether it is qualified; The adjustment mechanism 2 includes a U-shaped frame 201 slidably set on the support frame 101, a guide groove 202 set on the base 1, a scale 1 203 set on the U-shaped frame 201, a rectangular block 204 slidably set on the support frame 101, an adjustment groove 205 set on the support frame 101, a pushing column 206 rotatably set on the rectangular block 204, a spring 1 207 set on the rectangular block 204, and a scale 208 set on the base 1.

[0024] The ceramic substrate thickness detection device provided by the present invention solves the problem that the measuring device in the prior art cannot determine whether the thickness of the ceramic plate is uniform, resulting in errors in the measurement results. The present application adopts the adjustment mechanism 2, which rolls the roller 215 along the surface of the ceramic substrate and cooperates with the laser rangefinder 102 to quickly determine whether the thickness of the ceramic substrate is uniform, thereby realizing rapid detection of the thickness of the ceramic substrate. By setting the adjustment mechanism 2, when the roller 215 slides and resets, the support frame 101 squeezes the ceramic substrate, realizing automatic discharge of the ceramic substrate, solving the problem of low efficiency of manual discharge in the prior art; By setting the adjustment mechanism 2 and driving the rotation of the roller 215, the cleaning hole 222 is always in the exhaust state, thereby realizing automatic cleaning of the surface of the ceramic substrate and solving the problem of dust affecting detection accuracy in the prior art.

[0025] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein may be combined with each other.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0028] Example 1, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, a ceramic substrate thickness detection device, wherein the U-shaped frame 201 is slidably set on the guide groove 202, the push column 206 is slidably set on the adjustment groove 205, and the two ends of the spring 207 are respectively connected to the corresponding surfaces of the support frame 101 and the rectangular block 204; When using, such as Figure 1 As shown, a ceramic substrate is placed on the base 1, and the elasticity of the spring 1 207 causes the two rectangular blocks 204 to slide toward each other along the support frame 101. The push columns 206 on the two rectangular blocks 204 clamp and fix the ceramic substrate. The length and width of the ceramic substrate can be quickly read through the scale 1 203 and the scale 2 208, and then the U-shaped frame 201 is driven to slide along the guide groove 202. At this time, the U-shaped frame 201 and the support frame 101 are displaced synchronously, and the support frame 101 is tightly attached to the ceramic substrate by its own weight. When the thickness of the ceramic substrate is uneven, the support frame 101 will slide up or down along the U-shaped frame 201. When the support frame 101 moves up or down, the laser rangefinder 102 can quickly determine that the thickness of the ceramic substrate is uneven. On the contrary, the support frame 101 does not slide along the U-shaped rod, and the thickness of the ceramic substrate is uniform. Furthermore, an adapting groove 209 is provided on the U-shaped frame 201, an adapting cylinder 210 is slidably provided on the adapting groove 209, a driving column 206 is rotatably provided on the adapting cylinder 210, a rotating ring 211 is slidably provided on the driving column 206, and a second spring 212 is provided on the outer side of the driving column 206, and the two ends of the second spring 212 are respectively connected to the corresponding surfaces of the rotating ring 211 and the adapting cylinder 210. The second spring 212 drives the support frame 101 to be close to the ceramic substrate, thereby reducing the error of the laser rangefinder 102 in measuring the thickness of the ceramic substrate; Furthermore, a cavity 213 is provided on the rectangular block 204, and a rotating shaft 214 is rotatably provided in the cavity 213. A roller 215 is provided on the rotating shaft 214. When the U-shaped frame 201 slides along the guide groove 202, the U-shaped frame 201 and the support frame 101 are displaced synchronously, and the roller 215 on the support frame 101 rolls along the surface of the ceramic substrate. In this way, when detecting whether the ceramic substrate is uniform, the roller 215 rolls along the surface of the ceramic substrate, which can reduce friction of the device and prevent scratches on the surface of the ceramic substrate. Furthermore, a deflection slot 216 is provided on the base 1, a driving shaft 217 is rotatably provided on the deflection slot 216, and a limit block 218 is provided on the driving shaft 217; The ceramic substrate is limited by the limiting block 218, such as Figure 4 As shown, the elasticity of spring 1 207 makes the two rectangular blocks 204 slide toward each other along the support frame 101, and the push-up columns 206 on the two rectangular blocks 204 clamp and fix the ceramic substrate, and center the ceramic substrate. The length and width of the ceramic substrate are quickly measured by scale 1 203 and scale 2 208 to reduce measurement errors. Furthermore, the limit block 218 is adapted to the deflection slot 216 , and the drive shaft 217 and the deflection slot 216 are connected via a torsion spring; When the U-shaped frame 201 slides to the bottom of the guide groove 202, the support frame 101 is synchronously displaced and passes through the surface of the ceramic substrate. At this time, the roller 215 and the ceramic substrate are separated, and the two push columns 206 are separated from the squeezing of the two sides of the ceramic substrate. The elasticity of the spring 212 drives the support frame 101 downward, so that the roller 215 is close to the base 1, and then drives the U-shaped frame 201 to slide and reset. The support frame 101 slides and resets and squeezes the limit block 218, so that the limit block 218 rotates and closes. Figure 4 As shown, at this time, the support frame 101 resets and slides and pushes the ceramic substrate to enable the ceramic substrate to be discharged; Furthermore, a screw rod 219 is rotatably provided on the base 1, and the U-shaped frame 201 is threadedly connected to the screw rod 219. A motor 220 is provided on the base 1, and the screw rod 219 is connected to the output end of the motor 220. The U-shaped frame 201 is driven to slide along the guide groove 202 by the rotation of the screw rod 219, and the screw rod 219 is driven to rotate by the motor 220. The center positioning of the ceramic substrate is achieved through the adjustment mechanism 2, and the roller 215 rolls along the surface of the ceramic substrate. When the roller 215 slides up and down, with the help of the laser rangefinder 102, the uneven thickness of the ceramic substrate can be quickly detected. When the roller 215 slides back to its original position, the center limit of the ceramic substrate is released, and the ceramic substrate is automatically discharged.

[0029] Example 2 further optimizes the ceramic substrate thickness detection device provided in Example 1. Specifically, Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, a transfer chamber 221 is provided in the support frame 101, and a cleaning hole 222 is provided on the support frame 101. The transfer chamber 221 and the cleaning hole 222 are connected. A connecting pipe 223 is fixedly passed through the transfer chamber 221 and the cavity 213, and a piston plate 224 is slidably provided on the cavity 213; When the piston plate 224 slides, the piston plate 224 squeezes the air in the cavity 213 into the connecting pipe 223, and transfers the air to the transfer cavity 221 through the connecting pipe 223, and finally discharges the air from the cleaning hole 222 on the transfer cavity 221, wherein the cleaning hole 222 is inclined and arranged at the bottom of the support frame 101, as shown in FIG. Figure 5 As shown, the air discharged from the cleaning hole 222 can clean the dust or impurities on the surface of the ceramic substrate. Compared with the vertical setting, the inclined setting of the cleaning hole 222 is 45 degrees inclined. The airflow blown out of the cleaning hole 222 is tangential to the substrate surface. The dust or impurities are subjected to an oblique thrust, making it easier for the dust or impurities to break away from the surface of the ceramic substrate. The vertical airflow is only a positive pressure impact, and the impurities are easily pressed back to the surface. Furthermore, an elliptical groove 225 is provided on the roller 215, a connecting column 226 is provided on the piston plate 224, a ball 227 is rotatably provided on the connecting column 226, and a spring 228 is provided on the corresponding surfaces of the cavity 213 and the piston plate 224; Furthermore, the rectangular block 204 is provided with an external groove 229, a one-way valve 230 is provided on the external groove 229, the external groove 229 is connected to the cavity 213, and a one-way valve 231 is provided on the connecting pipe 223; The external groove 229 and the one-way valve 1 230 enable one-way communication between the outside and the cavity 213, and the one-way valve 231 realizes one-way communication between the connecting pipe 223 and the transfer cavity 221. When the roller 215 rolls along the surface of the ceramic substrate, the elliptical groove 225 on the roller 215 squeezes the ball 227, and the ball 227, the connecting column 226 and the piston plate 224 slide upward synchronously. The air in the cavity 213 is discharged into the transfer cavity 221 through the connecting pipe 223 and the one-way valve 231, and then the elasticity of the spring 3 228 drives the ball 227, the connecting column 226 and the piston plate 224 to slide downward synchronously, and the outside air enters the cavity 213 through the external groove 229 and the one-way valve 1 230. Then, when the roller 215 rotates, the exhaust hole is always in the exhaust state, thereby realizing automatic cleaning of the ceramic substrate. This prevents dust or impurities from causing the roller 215 to move up and down, thereby improving the measurement accuracy of the device. The adjustment mechanism 2 realizes automatic cleaning of the surface of the ceramic substrate, prevents dust or impurities from causing the roller 215 to move up and down, prevents dust or impurities from affecting the measurement, and improves the measurement accuracy of the device.

[0030] The use process of the ceramic substrate thickness detection device provided by the present invention is as follows: When in use, the ceramic substrate is placed on the base 1, and the elasticity of the spring 1 207 causes the two rectangular blocks 204 to slide toward each other along the support frame 101. The push columns 206 on the two rectangular blocks 204 clamp and fix the ceramic substrate, and the ceramic substrate is limited by the limit block 218 to center the ceramic substrate. The length and width of the ceramic substrate can be quickly read through the scale 1 203 and the scale 2 208. The motor 220 is started, and the motor 220 drives the screw 219 to rotate, and the screw 219 drives the U-shaped frame 201 Sliding along the guide groove 202, the U-shaped frame 201 and the support frame 101 move synchronously. When the support frame 101 moves upward or downward, the laser rangefinder 102 can quickly determine that the thickness of the ceramic substrate is uneven. On the contrary, the support frame 101 does not slide along the U-shaped rod, and the thickness of the ceramic substrate is uniform. The roller 215 on the support frame 101 is driven by the spring 212 to cling to the ceramic substrate. At this time, the roller 215 rolls along the surface of the ceramic substrate, and the elliptical groove 225 on the roller 215 squeezes the ball 227. The ball 227, The connecting column 226 and the piston plate 224 slide upward synchronously, and the air in the cavity 213 is discharged into the transfer cavity 221 through the connecting pipe 223 and the one-way valve 231. Then, the elasticity of the spring 3 228 drives the ball 227, the connecting column 226 and the piston plate 224 to slide downward synchronously, and the outside air enters the cavity 213 from the external groove 229 and the one-way valve 1 230. Then, when the roller 215 rotates, the exhaust hole is always in the exhaust state, realizing the automatic cleaning of the ceramic substrate. The surface of the substrate, at this time, the roller 215 and the ceramic substrate are separated, and the two pushing columns 206 are separated from the extrusion on both sides of the ceramic substrate. The elasticity of the spring 212 drives the support frame 101 to move down, so that the roller 215 is close to the base 1, and the output end of the motor 220 rotates in the opposite direction. The screw 219 drives the U-shaped frame 201 to slide and reset, and the support frame 101 slides and resets and squeezes the limit block 218, so that the limit block 218 rotates and closes. At this time, the support frame 101 resets, slides and pushes the ceramic substrate, so that the ceramic substrate is automatically discharged.
