Description

Technical Field

[0001] This invention relates to the field of linear displacement sensor detection equipment, specifically a linear displacement sensor detection equipment with automatic calibration function. Background Technology

[0002] Linear displacement sensors belong to the field of industrial automation measurement technology and are widely used in precision manufacturing, aerospace, automotive, and medical equipment. Their technology involves multiple disciplines, including mechanical design, electronic circuits, signal processing, and materials science. As a type of linear displacement sensor, laser displacement sensors often experience displacement due to vibration during use, leading to measurement errors and hindering accurate measurements. Therefore, we need a detection device to monitor for vibration during laser displacement sensor use. Upon detecting vibration, the device can automatically calibrate the laser displacement sensor to ensure its accuracy. Summary of the Invention

[0003] The purpose of this invention is to provide a linear displacement sensor detection device with automatic calibration function to solve the problems raised in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The testing equipment includes a base, a calibration module, a vibration detection module, a clamping module, a displacement cylinder, and a laser receiving plate. The vibration detection module is located at one end of the base and is fixedly connected to the base. The clamping module abuts against the upper surface of the vibration detection module and is slidably connected to the base. The displacement cylinder is located at the other end of the base and is fixedly connected to the base. The output direction of the displacement cylinder faces the clamping module. The laser receiving plate is fixedly connected to the output shaft of the displacement cylinder. The calibration module is located between the clamping module and the laser receiving plate and is fixedly connected to the base. The calibration module is signal-connected to the clamping module and to the vibration detection module.

[0006] The base serves as the mounting foundation. The calibration module, vibration detection module, clamping module, displacement cylinder, and laser receiving plate are mounted on the base. The clamping module is responsible for clamping the laser displacement sensor. The laser from the laser displacement sensor shines on the laser receiving plate. When the detection device vibrates due to impact or other external factors, the vibration detection module detects the vibration and sends a signal to the calibration module to calibrate the laser displacement sensor. At the same time, the laser displacement sensor turns off its laser. When the calibration module moves to a preset position, the laser displacement sensor turns on its laser for calibration. When the laser shines on the calibration module, the calibration module sends a signal to the clamping module. The clamping module rotates to adjust the angle of the laser displacement sensor, which has changed due to vibration, so that the laser from the laser displacement sensor passes through the calibration module and shines on the laser receiving plate, thus achieving automatic calibration of the laser displacement sensor angle.

[0007] Furthermore, the base is equipped with scale strips.

[0008] The scale bar can more intuitively display the distance between the laser receiver plate and the laser emission point of the laser displacement sensor.

[0009] Furthermore, the calibration module includes an electric cylinder, a calibration plate, an upper laser detection unit, and a lower laser detection unit. The electric cylinder is positioned between the laser receiving plate and the clamping module and is fixedly connected to the base. The electric cylinder is signal-connected to the vibration detection module. The calibration plate is fixedly connected to the output shaft of the electric cylinder. The calibration plate has a through hole. The upper laser detection unit is positioned directly above the through hole and is fixedly connected to the calibration plate. The lower laser detection unit is positioned directly below the through hole and is fixedly connected to the calibration plate. Both the upper and lower laser detection units are signal-connected to the clamping module.

[0010] When the vibration detection module detects vibration, it transmits a signal to the electric cylinder. The electric cylinder receives the signal and begins to operate, raising the calibration plate to a predetermined height and keeping the through hole in the path of the standard laser displacement sensor. When the laser shines on the upper laser detection unit, the upper laser detection unit transmits a signal to the clamping module, which rotates towards the calibration plate until the laser passes through the through hole. At this point, the upper laser detection unit stops transmitting signals to the clamping module, and the clamping module stops rotating. When the laser shines on the lower laser detection unit, the lower laser detection unit transmits a signal to the clamping module, which rotates away from the calibration plate until the laser passes through the through hole. At this point, the lower laser detection unit stops transmitting signals to the clamping module, and the clamping module stops rotating, thus achieving automatic calibration of the laser displacement sensor angle.

[0011] Furthermore, the upper laser detection unit includes a first photoresistor and a first circuit board. The first circuit board and the calibration plate are fixedly connected. The first photoresistor is fixedly connected to the calibration plate and electrically connected to the first circuit board. The first photoresistor is located on the side of the calibration plate facing the clamping module. The first photoresistor is located directly above the through hole. The first circuit board and the clamping module are signal connected.

[0012] When the laser shines on the first photoresistor, the resistance of the first photoresistor changes. After being amplified by the amplifier circuit on the first circuit board, the change is detected by the chip on the first circuit board. Then, the signal transmitter on the first circuit board transmits the signal to the clamping module. The clamping module receives the signal and rotates in the direction toward the calibration plate until the laser passes through the through hole. At this point, the upper laser detection unit stops transmitting signals to the clamping module, and the clamping module stops rotating.

[0013] Furthermore, the lower laser detection unit includes a second photoresistor and a second circuit board. The second circuit board and the calibration plate are fixedly connected. The second photoresistor and the calibration plate are also fixedly connected and electrically connected. The second photoresistor is located on the side of the calibration plate facing the clamping module. The second photoresistor is located directly below the through hole. The second circuit board and the clamping module are signal connected.

[0014] When the laser shines on the second photoresistor, the resistance of the second photoresistor changes. After being amplified by the amplifier circuit on the second circuit board, the change is detected by the chip on the second circuit board. The signal transmitter on the second circuit board then transmits the signal to the clamping module. The clamping module receives the signal and rotates in the direction away from the calibration plate until the laser passes through the through hole. At this point, the lower laser detection unit stops transmitting signals to the clamping module, and the clamping module stops rotating, thus achieving automatic calibration of the laser displacement sensor angle.

[0015] Furthermore, the vibration detection module includes a rubber damping seat, a magnet, a coil, and a third circuit board. The rubber damping seat is located at one end of the base and is fixedly connected to the base. The upper end of the rubber damping seat abuts against the bottom end of the clamping module. The third circuit board is fixedly connected to the base and is connected to the electric cylinder signal. The coil is electrically connected to the third circuit board. The magnet is fixedly connected to the bottom end of the clamping module and inserted into the coil.

[0016] The rubber shock absorber is responsible for reducing the vibration of the detection device caused by vibration or other factors, and maintaining the stable operation of the laser displacement sensor. When the vibration is too large, the clamping module presses down, causing the magnet to move inside the coil and cut the magnetic field lines of the coil. The chip on the third circuit board detects the change in current, and the signal transmitter on the third circuit board transmits the signal to the electric cylinder, causing the electric cylinder 21 to start operating, so that the calibration module calibrates the laser displacement sensor.

[0017] Furthermore, the clamping module includes a sliding base, a clamping seat, a clamping cylinder, a rotating seat, and a drive motor. The sliding base and the base are slidably connected. The bottom surface of the sliding base abuts against the upper surface of the rubber shock absorber. The upper surface of the sliding base is provided with a groove. The rotating seat is disposed at both ends of the groove and is fixedly connected to the sliding base. The clamping seat is located between the rotating seats at both ends. The output shaft of the drive motor passes through one end of the rotating seat and is fixedly connected to one end of the clamping seat. The other end of the clamping seat is rotatably connected to the other end of the rotating seat. The drive motor is signal-connected to the first circuit board and the second circuit board, respectively. The clamping cylinder and the clamping seat are fixedly connected. The output shaft of the clamping cylinder passes through both ends of the clamping seat. The clamping cylinders are symmetrically arranged on the clamping seat. The symmetrical axis plane of the clamping cylinder coincides with the vertical symmetrical axis plane of the through hole.

[0018] Symmetrically arranged clamping cylinders hold the laser displacement sensor, ensuring its stability. When the laser shines on the first photoresistor, the first circuit board transmits a signal to the drive motor, which rotates towards the calibration plate until the laser passes through the through hole. At this point, the first photoresistor stops transmitting signals to the drive motor, and the drive motor stops rotating. When the laser shines on the second photoresistor, the second circuit board transmits a signal to the drive motor, which rotates away from the calibration plate until the laser passes through the through hole. At this point, the second circuit board stops transmitting signals to the drive motor, and the drive motor stops rotating, thus achieving automatic calibration of the laser displacement sensor's angle.

[0019] Furthermore, a pointer is provided on the laser receiving plate, the pointer points to the scale bar, the pointer is fixedly connected to the laser receiving plate, and a laser receiving point is provided on the laser receiving plate, the line where the laser receiving point and the through hole are located is parallel to the horizontal plane.

[0020] The pointer, in conjunction with the scale bar, can more intuitively display the distance between the laser receiving plate and the laser emission point of the laser displacement sensor, making it easier for operators to observe.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The present invention is equipped with a vibration detection module. When the detection device experiences vibration that the rubber damping seat cannot offset, the magnet moves inside the coil, cutting the magnetic field lines of the coil. The chip on the third circuit board detects the change in current, and the signal transmitter on the third circuit board transmits the signal to the electric cylinder, causing the electric cylinder to start operating and enabling the calibration module to calibrate the laser displacement sensor.

[0023] 2. The present invention is provided with an upper laser detection unit. When the laser shines on the first photoresistor, the resistance of the first photoresistor changes. After being amplified by the amplifier circuit on the first circuit board, the change is detected by the chip on the first circuit board. Then, the signal transmitter on the first circuit board transmits the signal to the clamping module. The clamping module receives the signal and rotates in the direction toward the calibration plate until the laser passes through the through hole. At this point, the upper laser detection unit stops transmitting the signal to the clamping module, and the clamping module stops rotating.

[0024] 3. The present invention sets up a lower laser detection unit. When the laser shines on the second photoresistor, the resistance of the second photoresistor changes. After being amplified by the amplifier circuit on the second circuit board, the change is detected by the chip on the second circuit board. Then, the signal transmitter on the second circuit board transmits the signal to the clamping module. The clamping module receives the signal and rotates in the direction away from the calibration plate until the laser passes through the through hole. At this point, the lower laser detection unit stops transmitting the signal to the clamping module, and the clamping module stops rotating, thus realizing automatic calibration of the laser displacement sensor angle.

[0034] Example: Figure 1 - Figure 7 As shown, the present invention provides a technical solution for a linear displacement sensor detection device with automatic calibration function:

[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the testing equipment includes a base 1, a calibration module 2, a vibration detection module 3, a clamping module 4, a displacement cylinder 5, and a laser receiving plate 6. The vibration detection module 3 is located at one end of the base 1 and is fixedly connected to the base 1. The clamping module 4 abuts against the upper end face of the vibration detection module 3 and is slidably connected to the base 1. The displacement cylinder 5 is located at the other end of the base 1 and is fixedly connected to the base 1. The output direction of the displacement cylinder 5 faces the clamping module 4. The laser receiving plate 6 is fixedly connected to the output shaft of the displacement cylinder 5. The calibration module 2 is located between the clamping module 4 and the laser receiving plate 6 and is fixedly connected to the base 1. The calibration module 2 is signal-connected to the clamping module 4 and to the vibration detection module 3.

[0036] The base 1 serves as the mounting foundation. The calibration module 2, vibration detection module 3, clamping module 4, displacement cylinder 5, and laser receiving plate 6 are mounted on the base 1. The clamping module 4 is responsible for clamping the laser displacement sensor. The laser from the laser displacement sensor shines on the laser receiving plate 6. When the detection device vibrates due to impact or other external factors, the vibration detection module 3 detects the vibration and sends a signal to the calibration module 2 to calibrate the laser displacement sensor. At the same time, the laser displacement sensor turns off its laser. When the calibration module 2 moves to a preset position, the laser displacement sensor turns on its laser for calibration. When the laser shines on the calibration module 2, the calibration module 2 sends a signal to the clamping module 4. The clamping module 4 rotates to adjust the angle of the laser displacement sensor, which has changed due to vibration, so that the laser from the laser displacement sensor passes through the calibration module 2 and shines on the laser receiving plate 6, thus realizing the automatic calibration of the laser displacement sensor angle.

[0037] like Figure 1 As shown, a scale bar 11 is provided on the base 1.

[0038] The scale bar 11 can more intuitively display the distance between the laser receiving plate 6 and the laser emission point of the laser displacement sensor.

[0039] like Figure 3 and Figure 7 As shown, the calibration module 2 includes an electric cylinder 21, a calibration plate 22, an upper laser detection unit 23, and a lower laser detection unit 24. The electric cylinder 21 is disposed between the laser receiving plate 6 and the clamping module 4, and is fixedly connected to the base 1. The electric cylinder 21 is signal-connected to the vibration detection module 3. The calibration plate 22 is fixedly connected to the output shaft of the electric cylinder 21. The calibration plate 22 is provided with a through hole 29. The upper laser detection unit 23 is disposed directly above the through hole 29 and is fixedly connected to the calibration plate 22. The lower laser detection unit 24 is disposed directly below the through hole 29 and is fixedly connected to the calibration plate 22. Both the upper laser detection unit 23 and the lower laser detection unit 24 are signal-connected to the clamping module 4.

[0040] When the vibration detection module 3 detects vibration, it transmits a signal to the electric cylinder 21. The electric cylinder 21 receives the signal and starts working, raising the calibration plate 22 to a predetermined height and keeping the through hole 29 on the path of the standard laser displacement sensor. When the laser shines on the upper laser detection unit 23, the upper laser detection unit 23 transmits a signal to the clamping module 4. The clamping module 4 rotates in the direction toward the calibration plate 22 until the laser passes through the through hole 29. Then, the upper laser detection unit 23 stops transmitting a signal to the clamping module 4, and the clamping module 4 stops rotating. When the laser shines on the lower laser detection unit 24, the lower laser detection unit 24 transmits a signal to the clamping module 4. The clamping module 4 rotates in the direction away from the calibration plate 22 until the laser passes through the through hole 29. Then, the lower laser detection unit 24 stops transmitting a signal to the clamping module 4, and the clamping module 4 stops rotating, thus achieving automatic calibration of the laser displacement sensor angle.

[0041] like Figure 3 and Figure 7 As shown, the upper laser detection unit 23 includes a first photoresistor 25 and a first circuit board 26. The first circuit board 26 is fixedly connected to the calibration plate 22, and the first photoresistor 25 is fixedly connected to the calibration plate 22 and electrically connected to the first circuit board 26. The first photoresistor 25 is located on the side of the calibration plate 22 facing the clamping module 4. The first photoresistor 25 is located directly above the through hole 29. The first circuit board 26 is signal connected to the clamping module 4.

[0042] When the laser shines on the first photoresistor 25, the resistance of the first photoresistor 25 changes. After being amplified by the amplifier circuit on the first circuit board 26, the change is detected by the chip on the first circuit board 26. The signal transmitter on the first circuit board 26 then transmits the signal to the clamping module 4. The clamping module 4 receives the signal and rotates in the direction toward the calibration plate 22 until the laser passes through the through hole 29. At this point, the upper laser detection unit 23 stops transmitting the signal to the clamping module 4, and the clamping module 4 stops rotating.

[0043] like Figure 3 and Figure 7 As shown, the lower laser detection unit 24 includes a second photoresistor 27 and a second circuit board 28. The second circuit board 28 is fixedly connected to the calibration plate 22, the second photoresistor 27 is fixedly connected to the calibration plate 22, and electrically connected to the second circuit board 28. The second photoresistor 27 is located on the side of the calibration plate 22 facing the clamping module 4. The second photoresistor 27 is located directly below the through hole 29. The second circuit board 28 is signal connected to the clamping module 4.

[0044] When the laser shines on the second photoresistor 27, the resistance of the second photoresistor 27 changes. After being amplified by the amplifier circuit on the second circuit board 28, the change is detected by the chip on the second circuit board 28. The signal transmitter on the second circuit board 28 then transmits the signal to the clamping module 4. The clamping module 4 receives the signal and rotates in the direction away from the calibration plate 22 until the laser passes through the through hole 29. At this point, the lower laser detection unit 24 stops transmitting signals to the clamping module 4, and the clamping module 4 stops rotating, thus achieving automatic calibration of the laser displacement sensor angle.

[0045] like Figure 4 and Figure 5 As shown, the vibration detection module 3 includes a rubber damping seat 31, a magnet 32, a coil 33, and a third circuit board 34. The rubber damping seat 31 is disposed at one end of the base 1 and is fixedly connected to the base 1. The upper end surface of the rubber damping seat 31 abuts against the bottom end of the clamping module 4. The third circuit board 34 is fixedly connected to the base 1 and is signal-connected to the electric cylinder 21. The coil 33 is electrically connected to the third circuit board 34. The magnet 32 ​​is fixedly connected to the bottom end of the clamping module 4 and is inserted into the coil 33.

[0046] The rubber shock absorber 31 is responsible for reducing the vibration of the detection device caused by vibration or other factors, and maintaining the stable operation of the laser displacement sensor. When the vibration is too large, the clamping module 4 presses down, driving the magnet 32 ​​to move inside the coil 33, cutting the magnetic field lines of the coil 33. The chip on the third circuit board 34 detects the change in current, and the signal transmitter on the third circuit board 34 transmits the signal to the electric cylinder 21, causing the electric cylinder to start operating, so that the calibration module 2 calibrates the laser displacement sensor.

[0047] like Figures 4-6 As shown, the clamping module 4 includes a sliding base 41, a clamping seat 42, a clamping cylinder 43, a rotating seat 44, and a drive motor 45. The sliding base 41 is slidably connected to the base 1. The bottom end face of the sliding base 41 abuts against the upper end face of the rubber shock absorber 31. The upper end face of the sliding base 41 is provided with a groove 46. The rotating seat 44 is disposed at both axial ends of the groove 46 and is fixedly connected to the sliding base 41. The clamping seat 42 is located between the two rotating seats 44. The output shaft of the drive motor 45... One end of the rotating seat 44 and the clamping seat 42 are fixedly connected. The other end of the clamping seat 42 is rotatably connected to the rotating seat 44 at the other end. The drive motor 45 is signal connected to the first circuit board 26 and the second circuit board 28 respectively. The clamping cylinder 43 is fixedly connected to the clamping seat 42. The output shaft of the clamping cylinder 43 passes through both ends of the clamping seat 42. The clamping cylinder 43 is symmetrically arranged on the clamping seat 42. The symmetrical axis plane of the clamping cylinder 43 coincides with the vertical symmetrical axis plane of the through hole 29.

[0048] Symmetrically arranged clamping cylinders 43 clamp the laser displacement sensor to ensure its stability. When the laser shines on the first photoresistor 25, the first circuit board 26 transmits a signal to the drive motor 45, which rotates towards the calibration plate 22 until the laser passes through the through hole 29. At this point, the first photoresistor 25 stops transmitting signals to the drive motor 45, and the drive motor 45 stops rotating. When the laser shines on the second photoresistor 27, the second circuit board 28 transmits a signal to the drive motor 45, which rotates away from the calibration plate 22 until the laser passes through the through hole 29. At this point, the second circuit board 28 stops transmitting signals to the drive motor 45, and the drive motor 45 stops rotating, thus achieving automatic calibration of the laser displacement sensor's angle.

[0049] like Figure 3 As shown, a pointer 61 is provided on the laser receiving plate 6, the pointer 61 points to the scale bar 11, the pointer 61 is fixedly connected to the laser receiving plate 6, and a laser receiving point 62 is provided on the laser receiving plate 6. The line where the laser receiving point 62 and the through hole 29 are located is parallel to the horizontal plane.

[0050] The pointer 61, together with the scale bar 11, can more intuitively display the distance between the laser receiving plate 6 and the laser emission point of the laser displacement sensor, making it easier for operators to observe.

[0051] The working principle of this invention is as follows: When the vibration detection module 3 detects vibration, it transmits a signal to the electric cylinder 21. The electric cylinder 21 receives the signal and starts working, raising the calibration plate 22 to a predetermined height and keeping the through hole 29 on the path of the standard laser displacement sensor. The symmetrically arranged clamping cylinders 43 clamp the laser displacement sensor to ensure its stability. When the laser shines on the first photoresistor 25, the first circuit board 26 transmits a signal to the drive motor 45. The drive motor 45 rotates in the direction towards the calibration plate 22 until the laser passes through the through hole 29. At this point, the first photoresistor 25 stops transmitting a signal to the drive motor 45, and the drive motor 45 stops rotating. When the laser shines on the second photoresistor 27, the second circuit board 28 transmits a signal to the drive motor 45. The drive motor 45 rotates in the direction away from the calibration plate 22 until the laser passes through the through hole 29. At this point, the second circuit board 28 stops transmitting a signal to the drive motor 45, and the drive motor 45 stops rotating, thus achieving automatic calibration of the laser displacement sensor angle.
