Description

Technical Field

[0001] The present invention relates to the technical field of reflectivity measuring instruments, and particularly to a device for measuring high reflectivity. Background Art

[0002] In the field of detecting the optical properties of materials, accurately measuring the surface reflectivity of materials is of crucial significance for evaluating material quality, studying material characteristics, etc. At present, due to its convenience and flexibility, handheld reflectivity testers have been widely used in many industries such as material research and development, building material detection, printing industry, etc.

[0003] Before measuring the surface reflectivity of materials, existing handheld reflectivity testers need to perform calibration operations to ensure the accuracy of measurement results. Usually, accessories such as standard whiteboards or standard blackboards are used to complete this calibration process. The standard whiteboard is used to calibrate the instrument for measuring high reflectivity, while the standard blackboard is used to calibrate the measurement of low reflectivity.

[0004] However, this calibration method has many drawbacks. On the one hand, the calibration operation process is relatively cumbersome. The operator needs to first calibrate the instrument for high reflectivity using a standard whiteboard, and then use a standard blackboard for low reflectivity calibration. These steps need to be repeated before each measurement, consuming a lot of time and energy. On the other hand, the standard whiteboard, standard blackboard and handheld reflectivity tester adopt a split design, which means that in the actual use process, the operator needs to carry the tester, standard whiteboard and blackboard at the same time, not only increasing the carrying burden, but also easily causing the loss or damage of accessories. Once the accessories are missing or damaged, the tester cannot be accurately calibrated, and thus reliable measurement results cannot be obtained, seriously affecting work efficiency and the accuracy of detection. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a device for measuring high reflectivity to solve the technical problems in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A device for measuring high reflectivity, including a control mechanism. The control mechanism includes a control cylinder. Inside the control cylinder, a light source generating module, a lamp head, a control board, a control module and a battery module are installed at the bottom thereof. A touch operation screen electrically connected to the control board is installed on one side of the control cylinder;

[0007] A connecting block extending into the first calibration cylinder is fixed at the bottom of the control cylinder.

A light source through hole is provided between the first hemispherical shell and the second hemispherical shell. Inside the first hemispherical shell and the second hemispherical shell, a standard white board and a standard black board are rotatably connected;

[0010] Connectors are fixed at both ends between the standard white board and the standard black board. On one side of each group of connectors, a connecting frame is detachably connected. On one side of the connecting frame, a rotating shaft is fixed. On one side inside the first calibration cylinder, a motor fixed to one of the rotating shafts is installed. On one side between the first hemispherical shell and the second hemispherical shell, a sleeve movably connected to the other rotating shaft is provided;

[0011] On one side of the first calibration cylinder, a heat dissipation plate corresponding to the motor is provided, and the heat dissipation plate plays a role in dissipating heat and ventilating the motor;

[0012] The adjustment mechanism includes a fixed cylinder and an adjustment cylinder. The inner wall of the adjustment cylinder and the fixed cylinder are in threaded connection. At the bottom end of the inner wall of the adjustment cylinder, an inclined surface is provided. At the four corners of the bottom of the fixed cylinder, adjustment plates are rotatably connected. On the outside of each group of adjustment plates, a limiting rod in contact with the inclined surface is fixed;

[0013] The fixed cylinder and the adjustment plate are rotatably connected through a hinge seat. A torsion spring is provided inside the hinge seat, and the torsion spring plays an elastic connection role between the fixed cylinder and the adjustment plate. Rubber sheets are fixed between the four groups of adjustment plates, and a silica gel head is fixed at the bottom of the adjustment plate;

[0014] The four corners between the first calibration cylinder and the second calibration cylinder are tightly connected by second bolts, and the second calibration cylinder and the fixed cylinder are tightly connected by third bolts.

[0015] By adopting the above technical solutions, by installing a standard white board and a standard black board inside the device, automatic calibration is achieved through the motor and the touch operation screen. Compared with traditional split calibration accessories, it avoids the trouble of operators carrying and frequently replacing the standard white board and black board, saves time and energy, reduces the problem of inability to calibrate due to loss or damage of accessories, ensures that calibration can be quickly and accurately completed before each measurement, greatly improves work efficiency. At the same time, the adjustment mechanism can be adjusted according to the size of the material to be measured, adapting to the measurement of materials of different sizes. The design of the adjustment plate closely fitting the material surface enhances the stability of the measurement, reduces external light interference, and ensures the accuracy of the measurement even when measuring small-area materials, broadening the application range of the device and improving its use value.

[0036] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0037] Embodiment 1

[0038] A device for measuring high reflectivity, as Figures 1-13 shown, the device mainly consists of a control mechanism 1, a calibration mechanism 2 and an adjusting mechanism 3;

[0039] Inside the control cylinder 101 of the control mechanism 1, a variety of key components are integrated. The light source generating module 103 selects a high-brightness and stable-output LED light source, and with a high-quality optical lens, the light emitted by the lamp head 104 is uniform and the intensity is stable;

[0040] The control board 105 is a customized printed circuit board, equipped with a high-performance microcontroller and signal processing circuit, which is used to control devices such as the light source generating module 103 and the motor 210, and process measurement data. The control module 107 is responsible for coordinating the work of each component. It adopts an advanced embedded system, with high-efficient data processing capabilities and stable control performance. The battery module 108 selects a high-capacity lithium battery pack to provide continuous and stable power support for the entire device, and has overcharge and over-discharge protection functions to ensure safe use. The touch operation screen 106 uses a capacitive touch screen, with sensitive touch response and clear display effect, which is convenient for the operator to perform various operations and view measurement data. The connection block 109 at the bottom of the control cylinder 101 is tightly connected to the first calibration cylinder 201 of the calibration mechanism 2 through the first bolt 5 to ensure the stability of the connection;

[0041] The top of the control cylinder 101 is threadedly connected with a top cover 4, and the top cover 4 plays a role in closing the whole device. After opening the top cover 4, it is convenient for maintaining the internal devices;

[0042] Both the first calibration cylinder 201 and the second calibration cylinder 202 of the calibration mechanism 2 are made of high-strength engineering plastics. Through the injection molding process, the dimensional accuracy and structural strength are ensured. The first hemispherical shell 203 and the second hemispherical shell 204 are respectively fixed inside the first calibration cylinder 201 and the second calibration cylinder 202. They are made of optical-grade plastic materials, with good light transmittance and reflection performance;

[0043] The surfaces of the standard whiteboard 206 and the standard blackboard 207 are specially treated. The whiteboard has a high reflectivity, the blackboard has a low reflectivity, and the flatness is high to ensure the accuracy of calibration. The standard whiteboard 206 and the standard blackboard 207 are connected by a connecting plate 208, a connecting frame 209 and a rotating shaft 211, and are driven to rotate by the motor 210. The motor 210 selects a high-precision and low-noise micro motor, which is installed on one side inside the first calibration cylinder 201 and is movably connected to another group of rotating shafts 211 through a sleeve 212 to ensure the smoothness of rotation;

[0044] The heat dissipation plate 213 on one side of the first calibration cylinder 201 is made of aluminum alloy. Through the design of heat dissipation holes, it effectively dissipates the heat generated when the motor 210 works to ensure the stable operation of the motor. The positioning rod 214 at the bottom of the second hemispherical shell 204 is accurately inserted into the positioning cylinder 310 at the top of the fixed cylinder 301 of the adjusting mechanism 3 to ensure the accuracy and stability of the connection between the calibration mechanism 2 and the adjusting mechanism 3. The first calibration cylinder 201 and the second calibration cylinder 202 are tightly connected by a second bolt 6, and the second calibration cylinder 202 and the fixed cylinder 301 are tightly connected by a third bolt 7 to ensure the firm structure of the entire calibration mechanism 2;

[0045] The fixed cylinder 301 of the adjusting mechanism 3 is rotatably connected to the adjusting plate 303 through hinge seats 302 at the four corners of the bottom of the fixed cylinder 301. The torsion spring 304 inside the hinge seat 302 provides elastic support for the adjusting plate 303, so that the adjusting plate 303 maintains a certain angle when not subjected to external forces;

[0046] The limiting rod 305 on the outer side of the adjusting plate 303 cooperates with the inclined surface 307 at the bottom end of the inner wall of the adjusting cylinder 306. The adjusting cylinder 306 is threadedly connected to the fixed cylinder 301. Rotating the adjusting cylinder 306 can adjust the angle of the adjusting plate 303, thereby adjusting the contact area and stability between the measuring device and the surface of the material to be measured. The silica gel head at the bottom of the adjusting plate 303 increases the friction with the surface of the material to be measured to prevent the device from sliding during measurement. The rubber sheet 309 between the four groups of adjusting plates 303 plays a role in sealing and buffering, avoiding interference of external light on the measurement and reducing the collision noise between the adjusting plates 303;

[0047] Equipment Preparation and Charging

[0048] Before using the measuring device, connect it to a suitable power source for charging. Under the management of the control module 107, the two battery modules 108 convert external power into chemical energy and store it. During the charging process, the battery power status can be viewed through the touch operation screen 106. After the battery is fully charged, disconnect the power source and prepare for the measurement work;

[0049] Calibration Operation

[0050] When the reflectivity measurement is required, calibration is first performed. The operator starts the calibration program through the touch operation screen 106. The motor 210 starts to rotate under the control of the control board 105. The motor 210 drives the standard white board 206 to rotate under the lamp head 104. At this time, the lamp head 104 emits light and irradiates on the standard white board 206. The receiver built in the light source generating module 103 receives the reflected light. The control module 107 analyzes and calibrates according to the received optical signal, and stores the calibration data in the memory of the control board 105. After the white board calibration is completed, the motor 210 rotates again to rotate the standard black board 207 under the lamp head 104, and repeats the above calibration process to complete the black board calibration. The operator can repeat the calibration operation multiple times through the touch operation screen 106 to ensure the accuracy of the calibration;

[0051] Measurement Operation

[0052] After calibration is completed, the motor 210 rotates to make the standard white board 206 and the standard black board 207 in a vertical state. The light emitted by the lamp holder 104 passes through the light source through holes 205 of the first hemispherical shell 203 and the second hemispherical shell 204 and the round hole inside the fixed cylinder 301 in sequence, and irradiates the material to be detected outside. The light reflected from the material surface passes through the fixed cylinder 301, the second hemispherical shell 204 and the first hemispherical shell 203 again, and is received by the receiver of the light source generating module 103. The control module 107 compares and analyzes the received reflected light intensity with the calibration data, calculates the reflectivity of the material, and displays the measurement result on the touch operation screen 106:

[0053] The adjustment operation is for small-area operations

[0054] When the reflectivity needs to be measured on a material with a relatively small area, it is adjusted by rotating the adjustment cylinder 306. The adjustment cylinder 306 spirally descends relative to the fixed cylinder 301, and the inclined surface 307 on its inner side gradually squeezes multiple groups of limiting rods 305. The limiting rods 305 drive the adjustment plate 303 to rotate along the hinge seat 302, making the opening formed by multiple groups of adjustment plates 303 smaller, so as to closely fit the surface of the small-area material, improving the stability and accuracy of the measurement. After the adjustment is completed, the measurement is carried out according to the above measurement operation steps;

[0055] Equipment maintenance

[0056] After use, turn off the measuring device, clean the stains on the silicone head at the bottom of the adjustment plate 303 and the rubber sheet 309 to avoid affecting the accuracy of the next measurement. Regularly check whether the bolts at each connection part are loose, and tighten them in time if they are loose. Perform charge and discharge maintenance on the battery module 108 every once in a while to extend the battery life.

[0057] The working principle of the present invention is as follows: When in use, the device can be charged through the power supply. Under the action of the control module 107, the external power is transmitted to the two battery modules 108 and stored therein. When it is necessary to use the device to measure the reflectivity, the battery module 108 supplies power to the light source generating module 103, the motor 210 and the touch operation screen 106 through wires;

[0058] Before measurement, when calibration is required, the staff operates through the touch operation screen 106 to make the motor 210 rotate. At this time, the standard white board 206 is located below the lamp holder 104. At this time, the lamp holder 104 generates light for the white board calibration operation. Then the motor 210 flips 180 degrees, making the standard black board 207 located below the lamp holder 104 for the black board calibration operation. The staff only needs to operate through the touch operation screen 106 to perform multiple repetitive calibration operations on the standard white board 206 and the standard black board 207;

[0059] After the calibration is completed, the motor 210 rotates 90 degrees at this time, so that the standard white board 206 and the standard black board 207 are in a vertical state. Since there is a certain space between the standard white board 206 and the standard black board 207, when the standard white board 206 and the standard black board 207 are in a vertical state, the light source emitted by the lamp holder 104 enters the adjustment mechanism 3 through the light source through holes 205 of the first hemispherical shell 203 and the second hemispherical shell 204;

[0060] Since a round hole matching the light source through hole 205 is opened inside the fixed cylinder 301 of the adjustment mechanism 3, the light source generated by the lamp holder 104 can pass through the fixed cylinder 301 and irradiate on the material to be detected outside. When the light irradiates on the material surface, after the reflection of the light, the reflected light can be received by the receiver built in the light source generation module 103, so that the reflectivity of the material can be calculated;

[0061] As can be seen from the above, the device is internally provided with a standard white board 206 and a standard black board 207. When calibrating the device, the calibration operation can be automatically performed, effectively avoiding the problems in the prior art that it is necessary to carry a standard white board and a black board, increasing the carrying burden, and easily causing the loss or damage of accessories. At the same time, it avoids the problem that the tester cannot be accurately calibrated due to the lack or damage of accessories. Furthermore, reliable measurement results can be obtained more efficiently, improving the overall working efficiency and the accuracy of detection;

[0062] Furthermore, by adjusting the adjusting cylinder 306, the adjusting cylinder 306 is spirally lifted and lowered relative to the fixed cylinder 301 through the bolt 308. When the adjusting cylinder 306 rotates and descends, the inclined surface 307 inside it can gradually squeeze a plurality of limiting rods 305. Then the limiting rods 305 drive the adjusting plate 303 to rotate along the hinge seat 302, so that the size of the opening formed by a plurality of adjusting plates 303 can be adjusted, facilitating the measurement of the stability reflectivity on materials with a small area.

The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
