Description

Technical Field

[0001] This invention relates to the field of high-precision weighing equipment technology, specifically to a sensor-based horizontal compensation weighing device and a horizontal compensation weighing method. Background Technology

[0002] Many factors influence weighing results in high-precision weighing systems, among which the level of the measuring equipment has a significant impact. This is especially true in heavy-duty, high-precision testing systems, where the supporting structure of the equipment, such as the tabletop or the ground, may experience slight deformations under heavy loads. Even these minute deformations can have a considerable effect on the weighing results.

[0003] There is a lot of research on weighing equipment in the existing technology. When weighing objects, the common method to adjust the level of the weighing equipment is to have threaded adjusting feet at the four corners of the electronic scale to adjust the level position. By observing the bubble level on the weighing equipment, if the weighing equipment is not in a level position, it is necessary to adjust the threaded adjusting feet at the four corners to make the weighing equipment level, thereby achieving the accuracy of weighing. At present, the height of the threaded adjusting feet can be adjusted manually or automatically by motor drive.

[0004] However, the above methods still have the following shortcomings: when adjusting the level of the weighing equipment, it is often impossible to quickly locate the uneven position, and the platform of the weighing equipment cannot be adjusted to a level state in one go. It is necessary to adjust the lifting and lowering of the motor multiple times to adjust the platform to a level state, thus reducing work efficiency. Furthermore, small deformations cannot be accurately adjusted, resulting in low level accuracy and thus inaccurate measurement accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a sensor-based horizontal compensation weighing device and a horizontal compensation weighing method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A sensor-based horizontal compensation weighing device includes a weighing body placed on a table. A platform is fixedly connected to the top of the weighing body, and a bottom shell is fixedly connected to the bottom of the weighing body. The bottom of the bottom shell has a downward-opening cavity. Distance sensors are evenly arranged at the corners of the bottom surface of the platform. A first electric telescopic rod is respectively arranged on one side of several distance sensors. Several first electric telescopic rods are respectively fixedly connected to support columns. Sliding blocks are movably connected between adjacent support columns via first and second connecting rods. A limiting post disposed on the bottom surface of the platform is slidably connected to the center of each sliding block. Both sides are provided with fixing mechanisms for limiting the first connecting rod and the second connecting rod. The fixing mechanism includes a first sliding groove, a first insert rod, and a second insert rod. The first sliding groove is opened on the side of the sliding block. The first sliding groove is slidably connected to the first connecting rod and the second connecting rod. The sides of the first connecting rod and the second connecting rod are provided with grooves. The sliding block is also provided with a second sliding groove.

The end of the first insert rod and the second insert rod away from the groove is fixedly connected to the side of the first limiting rod. The other side of the first limiting rod is fixedly connected to the push rod.

[0008] The push rod is connected to an adjustment mechanism for adjusting the movement of the push rod. The adjustment mechanism includes a slot, a transition rod, and a second electric telescopic rod. The slot is formed inside the push rod. The transition rod is slidably connected to the slot. The top of the transition rod is fixedly connected to the second electric telescopic rod. The bottom of the second electric telescopic rod is fixedly connected to the top of the moving block. The moving block is slidably connected to a third sliding groove formed in the platform. One side of the moving block is fixedly connected to the third electric telescopic rod. The top of the transition rod is provided with a limiting mechanism for limiting the position of the transition rod inserted into the slot.

[0009] Preferably, the limiting mechanism includes a second limiting rod, a fourth sliding groove, and a fourth electric telescopic rod. The second limiting rod and the fourth sliding groove, which is opened in the transition rod, are slidably connected. A T-shaped rod is fixedly connected to one side of the second limiting rod. The end of the T-shaped rod away from the second limiting rod passes through the column. A telescopic rod is fixedly connected to the top of the T-shaped rod. The side wall of the telescopic rod is fixedly connected to a fifth electric telescopic rod fixedly connected to the moving block.

[0010] Preferably, the platform is square, and the number of distance sensors is [number missing].

[0011] Preferably, the distance sensor is an infrared distance sensor.

[0012] Preferably, the distance sensor and the controller are electrically connected, and the distance sensor is used to measure the distance information from the bottom shell to the desktop and transmit the distance information to the controller.

[0013] Preferably, a weight sensor is disposed at the center of the bottom surface of the bottom shell. The weight sensor is electrically connected to the controller. The weight sensor is used to acquire weighing data and transmit the weighing information to the controller.

[0014] Preferably, the first electric telescopic pole is equipped with an acceleration sensor, which is electrically connected to the controller.

[0015] To achieve the above technical solution, a sensor-based horizontal compensation weighing method is adopted, comprising the following steps:

[0016] S1. Place the weighing body on the table, with the bottom shell at the top of the table. The controller activates the distance sensor located at the corner of the bottom surface of the bottom shell to measure the distance h1 from the bottom shell to the top of the table before the table deforms, and sends the value of h1 to the controller.

[0017] S2. Place a heavy object on the table. Under the pressure of the heavy object, the top of the table will undergo a slight deformation. Measure the distance h2 from the bottom shell to the top of the table after the table is deformed, and send the value of h2 to the controller.

[0018] S3. Based on the data of h1 and h2, determine the location where the desktop has been deformed;

[0019] S4. If the tabletop located at the corner of the bottom surface A of the bottom shell is deformed, calculate the tabletop deformation h3, where h3 is the difference between the distance h1 from the bottom shell to the top of the tabletop before deformation and the distance h2 from the bottom shell to the top of the tabletop after deformation.

[0020] S5. If the tabletop located at the corner of the bottom surface B of the bottom shell is deformed, calculate the tabletop deformation h4, where h4 is the difference between the distance h1 from the bottom shell to the top of the tabletop before deformation and the distance h2 from the bottom shell to the top of the tabletop after deformation.

[0021] S6. If the tabletops located at the corners A and B on the bottom surface of the bottom shell are deformed, calculate the tabletop deformation h5, where h5 is the difference between the distance h1 from the bottom shell to the top of the tabletop before deformation and the distance h2 from the bottom shell to the top of the tabletop after deformation.

[0022] S7. The controller controls the first electric telescopic pole and the acceleration sensor to start, and uses the acceleration sensor to detect the acceleration a of the first electric telescopic pole;

[0023] S8. Using the desktop deformation h3 and acceleration a, or the desktop deformation h4 and acceleration a, or the desktop deformation h5 and acceleration a, calculate the action time t of the first electric telescopic pole according to the formula √(2h / a), so that the first electric telescopic pole starts for t seconds;

[0024] S9. After the table surface is leveled, the weight of the object is weighed using a weight sensor, and the result is sent to the weight sensor.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] This invention determines the location of tabletop deformation by evenly distributing distance sensors at the corners of the bottom surface of the base shell to detect the distance from the base shell to the top of the tabletop before and after placing a heavy object. The invention utilizes first electric telescopic rods, each fixedly connected to a support column on one side of the distance sensor. Adjacent support columns are movably connected via a first connecting rod, a second connecting rod, and a sliding block. The sliding block is slidably connected to a limiting post, and the first and second connecting rods are slidably connected to a first sliding groove. The first and second insert rods pass through the second sliding groove and are engaged with the groove. The ends of the first and second insert rods furthest from the groove are fixedly connected to the side of the first limiting rod. The other side of the first limiting rod is fixedly connected to the push rod, and the transition rod and the slot are slidably connected. The top of the transition rod is fixedly connected to the second electric telescopic rod, the bottom of the second electric telescopic rod is fixedly connected to the top of the moving block, the moving block is slidably connected to the third slide, and one side of the moving block is fixedly connected to the third electric telescopic rod. Therefore, after determining the area of ​​tabletop deformation corresponding to the table surface, the movement of the support columns located at the four corners A, B, C, and D can be controlled respectively, so that the uneven position can be quickly located. There is no need to adjust the lifting and lowering of the motor multiple times. The table surface of the weighing equipment can be adjusted to a horizontal state in one go, thereby improving work efficiency. Small deformations can also be accurately adjusted, thus increasing the horizontal accuracy. Attached Figure Description

[0038] Please see Figures 1 to 8 The present invention provides a technical solution:

Sliding blocks 9 are movably connected between adjacent support columns 6 via a first connecting rod 7 and a second connecting rod 8. The four corners A, B, C, and D are connected in pairs via the first connecting rod 7 and the second connecting rod 8. Figure 3 and Figure 4As shown, a limiting post 10 is slidably connected to the center of the sliding block 9 and disposed on the bottom surface of the platform 2. Fixing mechanisms for limiting the first connecting rod 7 and the second connecting rod 8 are provided on both sides of the sliding block 9. The fixing mechanisms include a first sliding groove 11, a first insert rod 12, and a second insert rod 13. The first sliding groove 11 is opened on the side of the sliding block 9 and is slidably connected to the first connecting rod 7 and the second connecting rod 8. Grooves 14 are provided on the sides of both the first connecting rod 7 and the second connecting rod 8. Figure 5 and Figure 6 As shown, a second sliding groove 15 is also provided on the sliding block 9. The first insert rod 12 and the second insert rod 13 pass through the second sliding groove 15 and are engaged with the groove 14. The ends of the first insert rod 12 and the second insert rod 13 away from the groove 14 are fixedly connected to one side of the first limiting rod 16, and the other side of the first limiting rod 16 is fixedly connected to the push rod 17.

[0040] like Figure 5 and Figure 6 as well as Figure 7 As shown, push rod 17 is connected to an adjustment mechanism for adjusting the movement of push rod 17. The adjustment mechanism includes a slot 18, a transition rod 19, and a second electric telescopic rod 20. The slot 18 is opened inside push rod 17. The transition rod 19 and slot 18 are slidably connected. The top of transition rod 19 is fixedly connected to the second electric telescopic rod 20. The bottom of the second electric telescopic rod 20 is fixedly connected to the top of moving block 21. Moving block 21 is slidably connected to a third sliding groove 22 opened in table 2. One side of moving block 21 is fixedly connected to the third electric telescopic rod 23. The top of transition rod 19 is provided with a limiting mechanism for limiting the position of transition rod 19 inserted into slot 18.

[0041] Based on the above embodiments, such as Figure 7 and Figure 8 As shown, the limiting mechanism includes a second limiting rod 24, a fourth sliding groove 25, and a fourth electric telescopic rod 26. The second limiting rod 24 and the fourth sliding groove 25, which is opened in the transition rod 19, are slidably connected. A T-shaped rod 27 is fixedly connected to one side of the second limiting rod 24. The end of the T-shaped rod 27 away from the second limiting rod 24 passes through the column 28. A telescopic rod 29 is fixedly connected to the top of the T-shaped rod 27. The side wall of the telescopic rod 29 is fixedly connected to the fourth electric telescopic rod 26, which is fixedly connected to the moving block 21.

[0042] Based on the above embodiments, the distance sensor 4 is an infrared distance sensor, specifically the GP2D12 manufactured by Sharp Corporation. The distance sensor 4 is electrically connected to the controller in the device. The distance sensor 4 receives signals from the controller to measure the distance information from the bottom shell 3 to the tabletop and transmits the distance information to the controller.

[0043] Based on the above embodiments, such as Figure 2As shown, a weight sensor 30 is set at the center of the bottom surface of the bottom shell 3. The weight sensor 30 is a 9330 type weight sensor produced by Xuzhou Weiteke Measurement and Control Technology Co., Ltd. The weight sensor 30 is electrically connected to the controller. The weight sensor 30 receives signals from the controller to acquire weighing data and transmits the weighing information to the controller.

[0044] Based on the above embodiments, an acceleration sensor is provided on the first electric telescopic pole 5. The acceleration sensor adopts the YMC series miniature acceleration sensor produced by Yangzhou Yingmaike Measurement and Control Technology Co., Ltd. The acceleration sensor and the controller are electrically connected. The acceleration sensor receives the signal from the controller to detect the acceleration information of the first electric telescopic pole 5 and transmits the acceleration information to the controller.

[0045] In this embodiment, by uniformly arranging distance sensors 4 at the corners of the bottom surface of the bottom shell 3, the distance from the bottom shell 3 to the top of the tabletop before and after placing the heavy object can be detected, thus determining the location where the tabletop deforms. A first electric telescopic rod 5 is provided on one side of each distance sensor 4, and is fixedly connected to the support column 6. Adjacent support columns 6 are movably connected via a first connecting rod 7, a second connecting rod 8, and a sliding block 9. The sliding block 9 is slidably connected to the limiting post 10, and the first connecting rod 7, the second connecting rod 8, and the first sliding groove 11 are slidably connected. The first insert rod 12 and the second insert rod 13 are inserted through the second sliding groove 15 and the groove 14 and engaged. The end of the first insert rod 12 and the second insert rod 13 away from the groove 14 is fixed to one side of the first limiting rod 16. The first limiting rod 16 is fixedly connected to the other side of the push rod 17, the transition rod 19 is slidably connected to the slot 18, the top of the transition rod 19 is fixedly connected to the second electric telescopic rod 20, the bottom of the second electric telescopic rod 20 is fixedly connected to the top of the moving block 21, the moving block 21 is slidably connected to the third slide groove 22, and one side of the moving block 21 is fixedly connected to the third electric telescopic rod 23. Therefore, after determining the area of ​​the tabletop corresponding to the deformation of the table surface 2, the support columns 6 located at the four corners A, B, C, and D can be controlled to move respectively, so that the uneven position can be quickly located. Without the need to adjust the lifting and lowering of the motor multiple times, the table surface of the weighing equipment can be adjusted to a horizontal state in one go, thereby improving work efficiency. Small deformations can also be accurately adjusted, thus increasing the horizontal accuracy.

[0046] To achieve the above technical solution, a sensor-based horizontal compensation weighing method is adopted, comprising the following steps:

[0047] S1. Place the weighing body 1 on the table, with the bottom shell 3 at the top of the table. The controller activates the distance sensor 4 located at the corner of the bottom surface of the bottom shell 3 to measure the distance h1 from the bottom shell 3 to the top of the table before the table deforms, and sends the value of h1 to the controller.

[0048] S2. Place a heavy object on the table 2. Under the pressure of the heavy object, the top of the table will undergo a slight deformation. Measure the distance h2 from the bottom shell 3 to the top of the table after the table is deformed, and send the value of h2 to the controller.

[0049] S3. Based on the data of h1 and h2, determine the location where the desktop has been deformed;

[0050] S4. If the tabletop located at the corner A of the bottom surface of the bottom shell 3 deforms, calculate the tabletop deformation h3. h3 is the difference between the distance h1 from the bottom shell 3 to the top of the tabletop before deformation and the distance h2 from the bottom shell 3 to the top of the tabletop after deformation. (Taking the fixing mechanism located on the upper side of the bottom surface of the bottom shell 3 as an example) Figure 5 As shown, at this time, the controller controls the fourth electric telescopic rod 26 to retract. The retraction of the fourth electric telescopic rod 26 pushes the telescopic rod 29 and the T-shaped rod 27 to move to the right until the second limit rod 24 slides to the rightmost edge. Then, the controller controls the third electric telescopic rod 23 to push the moving block 21 to slide to the left in the third slide groove 22, so that one end of the transition rod 19 extends out of the push rod 17 on the left side. The other side of the transition rod 19 separates from the push rod 17 on the right side. At this time, the controller drives the second electric telescopic rod 20 to extend downward, so that the first insert rod 12 is inserted into the groove 14, thereby fixing the connection between the first connecting rod 7 and the sliding block 9. Since the second connecting rod 8 connected to the B corner support column 6 is slidably connected to the first slide groove 11, at the same time, the second connecting rod 8 connected to the A corner support column 6 is fixedly connected to the sliding block 9, and the first connecting rod 7 connected to the D corner support column 6 is slidably connected to the first slide groove 11, so that the A corner support column 6 can extend downward independently.

[0051] S5. If the tabletop located at corner B on the bottom surface of the bottom shell 3 deforms, calculate the tabletop deformation h4, where h4 is the difference between the distance h1 from the bottom shell 3 to the top of the tabletop before deformation and the distance h2 from the bottom shell 3 to the top of the tabletop after deformation (taking corners A and B on the upper side of the bottom surface of the bottom shell 3 as an example). Figure 6As shown, at this time, the controller controls the second electric telescopic rod 20 to shorten upwards, and the movement of the second electric telescopic rod 20 drives the transition rod 19 to move upwards until it returns to the initial position, causing the first insertion rod 12 to be pulled out of the groove 14. Then, the controller controls the retraction of the fourth electric telescopic rod 26 to push the telescopic rod 29 and the T-shaped rod 27 to move to the left until the second limit rod 24 slides to the leftmost edge. Then, the controller controls the third electric telescopic rod 23 to push the moving block 21 to slide to the right in the third slide groove 22, causing one end of the transition rod 19 to extend out of the right push rod 17. When the push rod 17 on the other side and the left side separates, the controller drives the second electric telescopic rod 20 to extend downward, so that the second insert rod 13 is inserted into the groove 14, thereby fixing the connection between the second connecting rod 8 and the sliding block 9. Since the first connecting rod 7 and the first sliding groove 11 connected to the support column 6 at corner A are slidably connected, at the same time, the first connecting rod 7 and the sliding block 9 connected to the support column 6 at corner B are fixedly connected, and the second connecting rod 8 and the first sliding groove 11 connected to the support column 6 at corner C are slidably connected, so the support column 6 at corner B can extend downward independently.

[0052] S6. If the tabletop located at the corners of bottom surfaces A and B of tabletop 2 undergoes deformation, calculate the tabletop deformation h5, where h5 is the difference between the distance h1 from the bottom shell 3 to the top of the tabletop before deformation and the distance h2 from the bottom shell 3 to the top of the tabletop after deformation. Figure 7 As shown, at this time, the controller controls the second electric telescopic rod 20 to shorten upwards, and the movement of the second electric telescopic rod 20 drives the transition rod 19 to move upwards until it returns to the initial position, causing the second insertion rod 13 to be pulled out of the groove 14. Then, the controller controls the third electric telescopic rod 23 to push the moving block 21 to slide to the left in the third slide groove 22, so that one end of the transition rod 19 is located in the push rod 17 on the left, and the other end of the transition rod 19 is located in the push rod 17 on the right. Then, the controller controls the fourth electric telescopic rod 26 to extend, pushing the right telescopic rod 29 and the T-shaped rod 27 to move to the right. When the second limiting rod 24 slides to the rightmost edge, the controller drives the second electric telescopic rod 20 to extend downwards, so that the first insert rod 12 and the second insert rod 13 are inserted into the groove 14, thereby fixing the connection of the first connecting rod 7, the second connecting rod 8 and the sliding block 9, so that the A corner support column 6 and the B corner support column 6 are fixedly connected. At the same time, the second connecting rod 8 and the sliding block 9 connected to the A corner support column 6 are slidably connected, and the first connecting rod 7 and the sliding block 9 connected to the B corner support column 6 are slidably connected, so that the A corner and the B corner support columns 6 can move together.

[0053] S7. The controller controls the first electric telescopic pole 5 and the acceleration sensor to start, and uses the acceleration sensor to detect the acceleration a of the first electric telescopic pole 5;

[0054] S8. Using the desktop deformation h3 and acceleration a, or the desktop deformation h4 and acceleration a, or the desktop deformation h5 and acceleration a, according to the formula √(2h / a), h can be any one of h3, h4 or h5, calculate the action time t of the first electric telescopic rod 5. Make the first electric telescopic rod 5 start for t seconds, which can horizontally compensate for the problem of inaccurate weighing accuracy of the weighing body 1 caused by the slight deformation of the desktop.

[0055] S9. After the table 2 is leveled, the weight of the object is weighed using the weight sensor 30, and the result is sent to the controller.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

If the tabletops located at the corners A and B on the bottom surface of the bottom shell are deformed, calculate the tabletop deformation h5, where h5 is the difference between the distance h1 from the bottom shell to the top of the tabletop before deformation and the distance h2 from the bottom shell to the top of the tabletop after deformation. S7. The controller controls the first electric telescopic pole and the acceleration sensor to start, and uses the acceleration sensor to detect the acceleration a of the first electric telescopic pole; S8. Using the desktop deformation h3 and acceleration a, or the desktop deformation h4 and acceleration a, or the desktop deformation h5 and acceleration a, according to the formula √(2h / a), where h is chosen as any one of h3, h4 or h5, calculate the action time t of the first electric telescopic pole, so that the first electric telescopic pole starts for t seconds; S9. After the table surface is leveled, the weight of the object is weighed using a weight sensor, and the result is sent to the weight sensor.
