Description

Technical Field

[0001] The present invention relates to the technical field of laser measurement devices, and in particular, to a laser measurement device for measuring the rounded corners of tempered glass. Background Art

[0002] During laser measurement, ambient light or reflected light of the laser at other parts may enter the measurement optical path, generating stray light. This stray light will interfere with the laser signal, making the measured light intensity distribution inaccurate, and further affecting the accurate measurement of the glass rounded corner parameters. For example, the stray light may cause the measurement system to misjudge the boundary of the laser spot, resulting in the measured rounded corner radius being too large or too small. Moreover, there may be impurities such as dust, oil stains, and water stains on the glass surface. These impurities will change the optical properties of the glass surface and affect the reflection and refraction of the laser. For example, dust particles will cause the laser to scatter, and oil stains and water stains will absorb or scatter the laser, resulting in a weakening or distortion of the laser signal during measurement.

[0003] In the Chinese patent with the application number 202411481961.9, the invention discloses a laser measurement device and method for indoor decoration construction, including a transmission seat, a laser level measurement instrument body, and a glass protection plate. The output end of the transmission seat is fixedly connected to the bottom of the laser level measurement instrument body. By setting a transmission member, when the user starts the transmission seat to drive the laser level measurement instrument body to rotate clockwise for adjustment, the right side of the transmission member rotates towards the top, and then the transmission member will continuously drive the cleaning cotton to clean the front surface of the glass protection plate, solving the problem that a large amount of construction dust will be generated during decoration, and these construction dusts will fall on the glass protection plate at the laser emission part of the laser level measurement instrument. At this time, part of the laser emitted by the laser level measurement instrument will be blocked by the dust, resulting in the laser line being intermittent, thereby affecting the laser measurement effect of the laser level measurement instrument, and achieving the effect of cleaning the glass protection plate during adjustment.

[0004] When the existing laser measurement device measures the glass, it only cleans the front surface of the glass and does not clean the side edges of the rounded corners. The impurities adhered to the side edges of the rounded corners will make the side edges no longer flat and smooth. When the laser irradiates the part with impurities, irregular reflection and scattering will occur, resulting in the direction of the reflected light deviating from the normal path. The change in the direction of the reflected light will make the signal received by the measurement device inaccurate, thereby affecting the accuracy of the measurement result of the rounded corner edge of the tempered glass.

[0020] It is easily understood that according to the technical solution of the present invention, without changing the essential spirit of the present invention, those of ordinary skill in the art can propose various interchangeable structural forms and implementation manners. Therefore, the following specific embodiments and drawings are only exemplary illustrations of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0021] According to an embodiment of the present invention in combination with Figures 1 to 10 As shown, a laser measuring device for measuring the rounded corners of tempered glass includes a measuring device bottom plate 1. A glass support assembly 2 is installed on the top of the measuring device bottom plate 1. The glass support assembly 2 includes a hydraulic lifting rod 201, and the hydraulic lifting rod 201 is fixedly connected to the top of the measuring device bottom plate 1. The output end of the hydraulic lifting rod 201 is fixedly connected to a glass support platform 202. Two groups of adaptive grooves 203 are symmetrically arranged inside the glass support platform 202, and the adaptive grooves 203 and the glass support platform 202 are integrally provided. A glass conveyor belt 204 is arranged inside the adaptive grooves 203, and the adaptive grooves 203 and the glass conveyor belt 204 are in clearance fit. A fixed suction cup 205 is installed at the middle position of the glass support platform 202, and the fixed suction cup 205 is used for adsorbing and fixing the glass.

[0022] The glass conveyor belt 204 is used for conveying the glass that needs to be laser-measured at the rounded corner edge. During the conveying process, the glass support platform 202 descends. Under the action of the glass conveyor belt 204, the glass can move above it. When the glass is transported directly above the glass support platform 202, the hydraulic lifting rod 201 drives the glass support platform 202 to rise, so that the top surface of the glass support platform 202 is flush with the top surface of the glass conveyor belt 204, jointly playing a role in supporting the glass. At this time, the bottom of the glass conveyor belt 204 is embedded inside the adaptive grooves 203. At the same time, the fixed suction cup 205 extracts the internal air through a supporting air pump and uses negative pressure to adsorb and fix the glass on its top.

[0023] Pushing structures 3 are installed at the four corners of the top of the glass support platform 202. The output ends of the pushing structures 3 are fixedly connected to a light-shielding cover 6. A laser measuring instrument 8 is installed inside the light-shielding cover 6. A fitting groove 5 is opened at the bottom of the light-shielding cover 6.

[0024] The pushing structure 3 includes a support column. A ball screw slide rail structure is installed at the top of the support column. After the servo motor at the end of the ball screw starts, the nut on the screw can drive the light-shielding cover 6 through the slider, which is the output end of the pushing structure 3, to push the light-shielding cover 6 gradually towards the four rounded corners of the glass. The light-shielding cover 6 can be made of black plastic material, which can effectively block stray light in the surrounding environment, such as natural light, indoor light, etc. If this stray light enters the measurement optical path, it will be superimposed on the laser signal, interfering with the accurate capture of information such as the intensity and direction of the laser reflected light by the laser measuring instrument 8, thereby affecting the accuracy of the measurement result. The light-shielding cover 6 can effectively avoid this interference, enabling the light signal received by the measuring instrument to be mainly the laser reflected light from the rounded corners of the glass, improving the purity and stability of the signal. Transparent glass may produce refraction phenomena under different light conditions, affecting the accuracy of laser measurement. The black light-shielding cover 6 creates a relatively stable dark environment, reducing the refractive changes on the glass surface caused by external light, making the reflection and refraction of the laser at the rounded corners of the glass more stable, easier to measure and analyze, and helping to improve the measurement accuracy.

[0025] At the same time, the part of the bottom edge of the light-shielding cover 6 without the fitting groove 5 extends downward. During the pushing process, its bottom surface slides on the glass support table 202. The wiping component 4 can contract upward after encountering the side of the glass, while the extended part of the bottom edge of the light-shielding cover 6 cannot be retracted upward when encountering the side of the glass. Therefore, when the side of the extended part of the bottom of the light-shielding cover 6 contacts the side of the glass, the light-shielding cover 6 cannot be pushed further. When performing laser measurement on the rounded corners of different pieces of glass, the area where the light-shielding cover 6 is stuck outside the glass corner is the same, playing a positioning role. Thus, the position where the laser measuring instrument 8 installed inside the light-shielding cover 6 aligns with the glass corner each time is also limited, and it can be directly limited and aligned each time, making the measurement operation have high consistency and repeatability. The operator does not need to spend a lot of time and energy looking for and adjusting the measurement position, reducing the operation difficulty and improving the measurement efficiency. Due to the accuracy and consistency of the measurement positions of different glasses in the same batch, more comparable measurement results can be obtained, which is very important for quality control and data analysis, helping to timely detect changes in the size or shape of the glass corners, discover defective products, and ensure the stability of product quality.

[0026] The laser measuring instrument 8 includes a laser emitter and a sensor. The emitter forms a laser line through the optical elements inside and projects it onto the rounded corner of the glass. The surface of the glass rounded corner diffusely reflects the laser line, and the optical system projects the diffusely reflected light onto the photosensitive matrix of the highly sensitive sensor. The sensor calculates the position information of each point along the laser line direction and the distance information from the sensor to the object to be measured according to the received light conditions.

[0027] The laser measuring instrument 8 is installed inside the light-shielding cover 6 through its special mounting base. The mounting base is mainly composed of a linear guide rail, a slider, a mounting plate, and a driving device. The linear guide rail is fixed inside the light-shielding cover 6, the slider can slide freely on the guide rail, the mounting plate is connected below the slider for mounting the laser measuring instrument 8, and the driving device is set as a conventional motor and transmission mechanism for driving the slider to move along the guide rail. The laser measuring instrument 8 is driven by the mounting base to move along the guide rail to obtain the profile data of multiple scan lines from the top of the glass corner. These data are combined to form three-dimensional point cloud data, thereby realizing three-dimensional scanning imaging and presenting the three-dimensional shape and size of the glass rounded corner completely.

[0028] The wiping components 4 are arranged at equal intervals inside the fitting groove 5. The wiping component 4 includes a circular slot hole 401. A first spring 402 is nested inside the circular slot hole 401, and the bottom end of the first spring 402 is fixedly connected with a cylindrical rotating block 403. The bottom of the cylindrical rotating block 403 is fixedly connected with a square pressing block 404. A first inclined surface 405 is arranged at the bottom of the square pressing block 404, and a wiping cotton block 406 is fixedly connected to the bottom of the first inclined surface 405. The circular slot hole 401 is opened at the bottom of the light-shielding cover 6 and is communicated with the fitting groove 5. The top end of the first spring 402 is fixedly connected to the light-shielding cover 6. A first scraping block 407 is fixedly connected to the bottom end of the square pressing block 404. The cross-sectional shape of the first scraping block 407 is set as a right triangle, and the inclination angle of the hypotenuse of the first scraping block 407 is consistent with the inclination angle of the first inclined surface 405.

[0029] A scraping component 7 is installed on the inner wall of the square pressing block 404. The scraping component 7 is used for scraping and collecting impurities on the glass. The scraping component 7 includes a mounting notch 701, and the mounting notch 701 is opened on the inner wall of the square pressing block 404. A lifting slider 702 is slidably connected inside the mounting notch 701. The cross-sectional shape of the lifting slider 702 is set as a T shape. A second spring 703 is arranged inside the mounting notch 701. The top end of the second spring 703 is fixedly connected to the square pressing block 404, and the bottom end of the second spring 703 is fixedly connected to the lifting slider 702. The lifting slider 702 and the square pressing block 404 form an elastic structure through the second spring 703. When the second inclined surface 705 slides at the corner of the glass, the second spring 703 can be compressed, so that the second scraping block 704 can slide upward through the lifting slider 702. After moving to the top surface of the glass, the elastic force of the second spring 703 provides a downward pressure for the second scraping block 704, so that the lower side of the second inclined surface 705 presses on the top surface of the glass for sliding, improving the cleaning effect.

[0030] The part of the lifting slider 702 extending out of the mounting notch 701 is fixedly connected with a second scraping block 704. An indentation 706 is arranged on the inner wall of the second scraping block 704, and a second inclined surface 705 is arranged at the bottom end of the second scraping block 704. The inclination angle of the second inclined surface 705 is the same as that of the first inclined surface 405 and is also the same as that of the lower inclined surface of the first scraping block 407. After the first scraping block 407 completely moves above the glass corner, the first scraping block 407 returns to its initial shape after the external force is withdrawn, and its bottom edge is connected to the upper side edge of the second inclined surface 705, and the two maintain the same inclination angle, which can make the second inclined surface 705 continue to slide along the glass corner.

[0031] The side vertical surface of the first inclined surface 405 faces the glass. When the light-shielding cover 6 gradually advances towards the glass, the wiping cotton block 406 first contacts the side vertical surface of the glass, and it completely adheres to the side vertical surface of the glass. When the square pressing block 404 gradually approaches the glass, it gradually squeezes the wiping cotton block 406. At the same time, the first inclined surface 405 gradually slides along the corner of the side surface and the top surface of the glass, so that the square pressing block 404 compresses the first spring 402 and moves upward, and at the same time drives the wiping cotton block 406 to move upward together, which has a wiping effect from bottom to top on the side vertical surface of the glass. If there are impurities on the side of the glass, they will be gradually driven upward under the action of the wiping cotton block 406. The first scraping block 407 can be made of silica gel material. When the first scraping block 407 continues to move upward and contacts the corner of the glass, due to the certain toughness of the first scraping block 407, it bends backward under force, and the impurities collected on the bottom surface of the wiping cotton block 406 can be smoothly pushed into the interior of the indentation 706 for storage. At the same time, the upper side edge of the second inclined surface 705 continues to scrape upward the impurities near the corner on the side of the glass and collects them into the interior of the indentation 706. After the second inclined surface 705 completely rises above the glass, when the light-shielding cover 6 continues to push towards the glass, the wiping cotton block 406 slides over the top surface of the glass to wipe the top surface of the glass. At the same time, the elastic force of the first spring 402 maintains the continuous contact pressure between the wiping cotton block 406 and the glass surface to ensure uniform cleaning strength. Then the first scraping block 407 follows the wiping cotton block 406 to scrape the remaining traces of the wiping cotton block 406, and the silica gel material of the first scraping block 407 will not cause damage to the glass. At the same time, the lower side edge of the second inclined surface 705 also slides over the top surface of the glass to perform a third scraping and cleaning of the top surface of the glass.

[0032] The wiping cotton block 406 first contacts the side vertical surface of the glass and fits completely. Under the action of the first inclined surface 405, the square pressing block 404 moves upward, realizing wiping the side from bottom to top, efficiently removing impurities on the side. If there are impurities on the side of the glass rounded corner, when the laser irradiates on the impurities, irregular reflection, scattering or absorption may occur, resulting in inaccurate signals returned by the laser. After cleaning the impurities on the side, the laser can be reflected more accurately from the glass surface, making the signals received by the measurement system more stable and accurate, thereby improving the measurement accuracy. The first scraping block 407 is made of silica gel material. When contacting the glass corner, it bends using its own toughness and smoothly pushes the impurities collected on the bottom surface of the wiping cotton block 406 into the notch 706 for storage. At the same time, the upper side of the second inclined surface 705 continues to scrape and collect the impurities near the corner of the glass side, forming a comprehensive cleaning process for the glass side, greatly improving the cleaning efficiency and thoroughness, preventing impurities from remaining at the corners of the glass side and top during the wiping process, and effectively improving the accuracy of laser measurement.

[0033] A splicing sliding groove 408 is provided on one side of the square pressing block 404, and a splicing sliding block 409 is provided on the other side of the square pressing block 404. The splicing sliding block 409 is flexibly connected to the square pressing block 404 and is adapted to the splicing sliding groove 408.

[0034] Each adjacent two groups of square pressing blocks 404 are slidably connected together through the splicing sliding blocks 409 and splicing sliding grooves 408 on their sides. The splicing sliding blocks 409 are embedded inside the splicing sliding grooves 408, which can seal the gaps between adjacent two groups of square pressing blocks 404, thereby improving the sealing performance of the entire light-shielding cover 6 during the laser detection process. After being squeezed, each wiping cotton block 406 will undergo a certain deformation, which can fill the gaps between each wiping cotton block 406 to avoid wiping residues. Moreover, the width of the first scraping block 407 is the same as the width of the notch 706 and is slightly larger than the width of the square pressing block 404. When spliced together, the gaps between them can also be minimized as much as possible to improve the wiping effect and ensure the complete removal of impurities.

[0035] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
