Description

Technical Field

[0001] The invention relates to the field of glass detection, and in particular to a device and method for testing the flatness of architectural glass. Background Art

[0002] Architectural glass is a glass material used for building facades, windows, skylights and other building components. It has good lighting, transparency and sound insulation performance. With the increasing richness and high-end of architectural design, architectural glass is increasingly used in the construction field and has become an important material for modern building design, construction and decoration. In the process of producing architectural glass, it is necessary to ensure the flatness of the surface of the architectural glass to achieve good transparency, and then separate it into various styles according to needs. Therefore, it is particularly important to test the flatness of the surface of the architectural glass.

[0003] Existing testing equipment can only test one side of the glass at a time. When the other side needs to be tested, the glass needs to be turned over again, which is troublesome to operate. It not only increases the operation time and labor costs, but may also cause potential damage to the glass during the turning process. When trying to test the bottom of the glass, it is easily blocked by the supporting components, resulting in incomplete testing and affecting the accuracy of the test results.

[0024] Preferably, the driving mechanism further comprises an elliptical groove and a balancing pin, wherein the elliptical groove is provided on the side wall of the elliptical plate, the balancing pin is rotatably connected to the side wall of the mounting frame, and the end of the balancing pin extends into the elliptical groove.

[0025] In a second aspect, a testing method for a building glass flatness testing device is provided, the testing method comprising the following steps:

[0026] Step 1: Limiting the glass: After the sensing unit detects that the glass is located at the test station, it generates detection information and sends it to the control unit. The control unit controls the operation of two dual-function limiting mechanisms to clamp the side wall of the glass to be tested and support the bottom;

[0027] Step 2: Cancel the support of the lifting platform: Move the lifting platform away from under the glass through the control unit to cancel the support of the lifting platform under the glass;

[0029] Preferably, the control process of the control unit includes the following steps:

[0030] After receiving the detection information generated by the sensing unit, the control unit generates first control information, second control information and third control information;

[0031] The control unit first sends the first control information to the two dual-function limit mechanisms, starts the two second electric cylinders, and the piston rods of the two second electric cylinders push the two clamping plates to clamp and limit the two sides of the glass and support the bottom;

[0032] The control unit then sends the second control information to the lifting platform to cancel the support of the lifting platform under the glass;

[0033] The control unit sends the third control information to the two driving mechanisms, driving the mounting frame to move along the elliptical track of the elliptical plate, thereby realizing flatness detection on both the upper and lower surfaces of the glass.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. This design has significant advantages over traditional methods. First, the elliptical trajectory design enables simultaneous inspection of both sides of the glass, avoiding flipping operations and greatly improving efficiency. Second, the dynamic adjustment of the dual-function limit mechanism ensures that the glass can get proper bottom support during the entire inspection process, avoiding the problem of material fatigue and reduced clamping force due to long-term suspended clamping of the glass, and significantly improving operational safety.

[0036] 2. The control unit controls the second electric cylinder to start, and the piston rod of the second electric cylinder will push the clamping plate to move to one side of the glass, and use the clamping plate to clamp the side wall of the glass, so as to achieve suspended clamping of the glass, and then there is no need to turn the glass over during inspection, and the flatness of the bottom of the glass can be inspected. However, if the suspended glass side walls are clamped by the clamping plates on both sides for a long time, the material fatigue of the clamping plates may be caused, thereby reducing the clamping force and friction, and the glass may gradually move down or lose balance. Therefore, when the clamping plate moves to one side of the glass for clamping, several support plates will move synchronously to the bottom of the glass to achieve synchronous support for the bottom of the glass. When the mounting frame drives the optical detector to move along the elliptical trajectory to the bottom of the glass, it is necessary to scan and inspect the lower surface of the glass. In the process of horizontal movement below the glass, the toggle mechanism will push the passing spheres in turn. The pushed spheres are forced to move into the sliding groove with the help of the mounting plate to drive the support plate, and at the same time compress the spring, thereby canceling the support of the support plate around the detection for the bottom of the glass, avoiding the phenomenon of blocking the light beam emitted by the optical detector. As the mobile detection continues, the previously pushed sphere is no longer pushed by the toggle mechanism. At this time, the compressed spring will recover and generate a recovery impact force, thereby pushing the corresponding support plate end to the outside of the sliding groove and supporting the bottom of the glass again. This dynamic adjustment can not only stably clamp and support the glass, but also dynamically adjust the support position during the test, effectively reducing the occurrence of clamping force damage caused by the weight of the glass, and ensuring the detection accuracy.

DETAILED DESCRIPTION

[0047] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0048] Application scenarios: In the process of flatness inspection of architectural glass, the existing technology has some obvious limitations. First, the inspection equipment can usually only inspect one side of the glass and cannot comprehensively evaluate both sides at the same time. This requires additional flipping operations during the inspection process, which not only increases the operation time and labor costs, but may also cause potential damage to the glass during the flipping process. Secondly, when trying to inspect the bottom of the glass, the supporting components often block the line of sight of the inspection equipment, affecting the accuracy of the inspection results. Finally, in order to achieve inspection of both sides of the glass, the method of clamping the glass in mid-air is further optimized. However, this method may cause material fatigue of the clamping mechanism or the glass itself due to gravity under long-term operation, thereby reducing the clamping force and friction, and increasing the risk of glass falling or damage during the inspection process. These problems seriously affect the efficiency, accuracy and safety of architectural glass flatness inspection.

[0049] For example, on a large-scale architectural glass production line, hundreds of large-size architectural glasses need to be inspected for flatness every day. The existing inspection system adopts a single-sided inspection method. The operator needs to manually place each piece of glass on the inspection table. After inspecting one side, the glass needs to be flipped over to inspect the other side. This process is not only time-consuming, but also due to the heavy weight of the glass, there are safety hazards in the flipping operation. In order to improve efficiency, some factories try to use a clamping device to suspend the glass in the air, but after working for several hours in a row, due to the effect of gravity and material fatigue, the glass may gradually move down or lose balance, increasing the risk of the glass falling. If these technical problems are not effectively solved, it will have a serious negative impact on the quality control and production efficiency of architectural glass. Therefore, the development of an intelligent inspection device that can simultaneously perform comprehensive inspections on both sides of the glass, avoid interference from supporting components, and solve the problem of long-term clamping is of great practical significance for improving the quality, efficiency and safety of architectural glass. In order to meet these challenges, the present application proposes an innovative solution.

[0050] like Figures 1 to 8 The flatness testing device for building glass shown in the figure comprises a support frame 1, a lifting platform is arranged on the inner bottom surface of the support frame 1, and the lifting platform is used to support the glass to be tested on the testing station, and also comprises:

[0051] Two elliptical plates 2 are symmetrically fixedly connected to the two ends of the support frame 1;

[0052] Two dual-function limit mechanisms are respectively arranged on opposite sides of the two elliptical plates 2, and are used together to clamp the two sides of the glass to be tested and support the bottom;

[0053] A mounting frame 3 is arranged on the surfaces of the two elliptical plates 2, and an optical detector 4 is installed at the bottom of the mounting frame 3;

[0054] Two driving mechanisms are respectively arranged on the side walls of the two elliptical plates 2, and are used together to drive the mounting frame 3 to move along the elliptical track of the elliptical plate 2;

[0055] The sensing unit is used to detect the position of the glass on the test station;

[0056] The control unit first controls the operation of the two dual-function limit mechanisms according to the detection result of the sensing unit, and then controls the lifting platform to cancel the support and controls the two driving mechanisms to drive the mounting frame 3 to move along the elliptical trajectory. When the mounting frame 3 moves under the glass, the dual-function limit mechanism is triggered to dynamically adjust the support for the bottom of the glass. When working, the glass to be tested is moved to the lifting platform with the help of an external manipulator. After the sensing unit detects that the glass is completely in the test position, the control unit first controls the operation of the two dual-function limit mechanisms, and clamps both sides of the glass on the test position and supports the bottom with the help of the two dual-function limit mechanisms. Then, the lifting platform is controlled to cancel the support for the bottom of the glass to avoid the lifting platform blocking the bottom of the glass during subsequent flatness detection. When a phenomenon that affects the optical detector 4 from scanning the bottom of the glass occurs, the mounting frame 3 connected to the optical detector 4 is driven to move along an elliptical trajectory by two driving mechanisms. During the movement of the mounting frame 3, the optical detector 4 emits a light beam to scan the upper and lower surfaces of the glass in turn. When the mounting frame 3 equipped with the optical detector 4 is converted to move under the glass along the elliptical trajectory, the dual-function limit mechanism is triggered during the movement to dynamically adjust and support the bottom of the glass, so that the dual-function limit mechanism cancels the support for the bottom of the glass around the mounting frame 3 to avoid obstruction of the light beam of the optical detector 4. Support is still maintained at other positions to avoid the glass being clamped in the air, so that the glass is in a stable state during the entire detection process.

[0057] This design has significant advantages over traditional methods. First, the elliptical trajectory design enables simultaneous inspection of both sides of the glass, avoiding flipping operations and greatly improving efficiency. Second, the dynamic adjustment of the dual-function limit mechanism ensures that the glass can get proper bottom support during the entire inspection process, avoiding the problem of material fatigue and reduced clamping force due to long-term suspended clamping of the glass, and significantly improving operational safety.

[0058] As an embodiment of the present invention, the lifting platform includes a first electric cylinder 5, which is fixedly mounted on the inner bottom surface of the support frame 1, and the piston rod end of the first electric cylinder 5 is fixedly connected to a support box 6, and a plurality of conveying rollers 7 are rotatably connected to the inner wall of the support box 6; when working, one end of the glass to be tested is placed on the conveying roller 7 with the help of an external manipulator, and the glass is continuously pushed so that the glass moves along the conveying roller 7 to the test station. The provided conveying roller 7 is conducive to reducing the friction of the glass during movement. When the sensing unit detects that the glass has completely reached the test station, it means that the glass has been placed, and then two dual-function limit mechanisms are used to clamp the two sides of the glass and support the bottom. After the dual-function limit mechanism completes the operation, the control unit starts the first electric cylinder 5, and the piston rod of the first electric cylinder 5 will drive the support box 6 with the conveying roller 7 installed to move downward, thereby canceling the support of the lower surface of the glass by the plurality of conveying rollers 7, thereby facilitating the optical detector 4 to perform flatness detection on the lower surface of the glass, and avoiding the occurrence of obstructions affecting the scanning effect during the scanning of the lower surface of the glass by the optical detector 4.

[0059] As an embodiment of the present invention, the sensing unit includes a blocking plate 8, which is fixedly mounted on the top of the support box 6. A pressure sensor 9 is mounted on the side wall of the blocking plate 8. The pressure sensor 9 senses pressure and is used to identify the position of the glass on the test station. During operation, when the glass moves along the conveying roller 7 to the test station, when the end of the glass touches one side of the blocking plate 8 and presses the pressure sensor 9, the pressure sensor 9 senses the pressure and generates detection information, thereby accurately identifying that the glass has arrived at the test station, and sending the detection information to the control unit to intelligently control the flatness testing device. This not only improves the degree of automation of the testing process, but also reduces the possibility of inaccurate detection due to human operational errors, thereby improving the overall work efficiency. Compared with traditional detection methods, this technical solution has obvious advantages in terms of operational convenience and reliability.

[0060] As an embodiment of the present invention, the dual-function limit mechanism includes:

[0061] A placement groove 10 is provided on the side wall of the elliptical plate 2, a clamping plate 11 is slidably connected to the inner wall of the placement groove 10, and a non-slip pad is provided on the side of the clamping plate 11 facing the glass;

[0062] The two second electric cylinders 12 are fixedly mounted on the side walls of the elliptical plate 2. The ends of the piston rods of the two second electric cylinders 12 penetrate the elliptical plate 2 and extend into the placement groove 10 and are fixedly connected to the clamping plate 11.

[0063] A plurality of sliding grooves 13 are provided in a linear array on the side wall of the clamping plate 11. A rectangular opening 14 is provided through the inner bottom surface of each sliding groove 13. A support plate 15 is slidably connected to the groove wall of each sliding groove 13. A spring 16 is fixedly connected between each support plate 15 and the inner wall of the corresponding sliding groove 13. A mounting plate 17 is fixedly connected to the bottom of each support plate 15. The lower end of each mounting plate 17 passes through the adjacent rectangular opening 14 and extends out. A second mounting seat 18 is fixedly installed on the lower end side wall of each mounting plate 17. A ball 19 is rotatably connected to each mounting seat.

[0064] The toggle mechanism is arranged on the inner wall of the mounting frame 3, and pushes the spheres 19 at different positions as the mounting frame 3 moves; when working, the control unit controls the second electric cylinder 12 to start, and the piston rod of the second electric cylinder 12 will push the clamping plate 11 to move to one side of the glass, and use the clamping plate 11 to clamp the side wall of the glass, so as to achieve suspended clamping of the glass, and then the bottom of the glass can be tested for flatness without turning the glass over during detection. However, if the suspended glass side walls are clamped by the clamping plates 11 on both sides for a long time, the material fatigue of the clamping plates 11 may be caused, thereby reducing the clamping force and friction, and the glass may gradually move down or lose balance. Therefore, when the clamping plate 11 moves to one side of the glass for clamping, the several support plates 15 set will move synchronously to the bottom of the glass to achieve synchronous support for the bottom of the glass. When the mounting frame 3 drives the optical detector 4 to move along the elliptical trajectory to the glass At the bottom, when it is necessary to scan and detect the lower surface of the glass, during the horizontal movement of the bottom of the glass, the toggle mechanism will push the passing spheres 19 in turn. The pushed spheres 19 are forced to drive the support plates 15 to move into the sliding groove 13 with the help of the mounting plate 17, and at the same time compress the springs 16, thereby canceling the support of the support plates 15 around the detection for the bottom of the glass, avoiding the phenomenon of blocking the light beam emitted by the optical detector 4. As the mobile detection continues, the previously pushed spheres 19 are no longer pushed by the toggle mechanism. At this time, the compressed springs 16 will recover and generate a recovery impact force, thereby pushing the corresponding end of the support plate 15 to the outside of the sliding groove 13, and supporting the bottom of the glass again. This dynamic adjustment can not only stably clamp and support the glass, but also dynamically adjust the support position during the test, effectively reducing the occurrence of clamping force damage caused by the weight of the glass, and ensuring the detection accuracy.

[0065] As an embodiment of the present invention, the toggle mechanism includes:

[0066] A connecting plate 20, fixedly connected to the inner wall of the mounting frame 3;

[0067] The toggle plate 21 is fixedly connected to the end of the connecting plate 20. A horizontal surface 2101 and a symmetrically opened inclined surface 2102 are provided on the side wall of the toggle plate 21. The inclined surface 2102 is adapted to the surface of the ball 19. When working, the toggle plate 21 is synchronously driven to move with the help of the connecting plate 20 as the mounting frame 3 moves. When the mounting frame 3 moves to the bottom of the glass and moves horizontally, the inclined surface 2102 of the toggle plate 21 will contact and push the ball 19 at different positions in turn. When the inclined surface 2102 on the toggle plate 21 pushes the surface of the ball 19, the ball 19 The surface of the sphere 19 is subjected to force, thereby pushing the support plate 15 to move into the sliding groove 13 through the corresponding mounting plate 17, thereby canceling the support of the support plate 15 on the bottom of the clamped suspended glass, and in the process that the horizontal plane 2101 of the toggle plate 21 contacts the surface of the sphere 19, the pushing force on the surface of the sphere 19 is always maintained, maintaining the state in which the support plate 15 cancels the support for the bottom of the glass, avoiding the support plate 15 from blocking the bottom of the glass during the detection process, thereby ensuring that there is no obstruction to the bottom of the glass around the detection of the optical detector 4.

[0068] The contact area between the inclined surface 2102 on the toggle plate 21 and the surface of the sphere 19 can be optimized by adjusting the curvature of the inclined surface 2102 to make the driving force more uniform. The inclined surface 2102 can be designed to be slightly arc-shaped to better fit the surface of the sphere 19 and improve the driving efficiency.

[0069] As an embodiment of the present invention, the optical detector 4 is provided with a detection laser beam 401 and a photoresistor plate 402, and the photoresistor plate 402 is composed of a plurality of groups of small photoresistors. When working, the detection laser beam 401 is used to emit a laser beam, and the laser beam irradiated on the glass is reflected to the photoresistor plate 402 through the refraction of the glass. The photoresistor plate 402 is composed of a plurality of groups of small photoresistors, and can accurately detect the position change of the laser after passing through the glass. The photoresistor plate 402 where the laser beam is arranged receives light at different positions and converts the optical signal into an electrical signal to analyze the flatness of the glass plate, which greatly improves the convenience and accuracy of the flatness detection of the glass. Therefore, by the cooperation of the detection laser beam 401 and the photoresistor plate 402, when the laser passes through the glass surface, if the glass surface is uneven, the laser will be deflected, thereby changing the position where the laser reaches the photoresistor plate 402, thereby detecting the uneven position of the glass surface, and the detection process is fast, efficient and accurate.

[0070] As an embodiment of the present invention, the driving mechanism includes a mounting groove 22, the mounting groove 22 is opened on the side wall of the elliptical plate 2, and two sprockets 23 are rotatably connected to the inner wall of the mounting groove 22. The surfaces of the two sprockets 23 are commonly meshed with a chain 24. Two connecting columns are fixedly connected to one of the chain plates of the chain 24. The two connecting columns are fixedly connected to the inner wall of the mounting frame 3. A first mounting seat 26 is fixedly installed on the inner wall of the mounting groove 22, and a motor 25 is fixedly installed on the first mounting seat 26. The output shaft end of the motor 25 is adjacent to The sprocket 23 is fixedly connected; when working, the control unit starts the motor 25, and the output shaft of the motor 25 will drive the sprocket 23 fixedly connected thereto to rotate. Since the sprocket 23 and the chain 24 are meshed, the rotation of the sprocket 23 causes the chain 24 to rotate. As the chain 24 rotates, the two connecting columns connected to the chain plate will pull the mounting frame 3 to move synchronously, thereby driving the mounting frame 3 to move along the elliptical trajectory of the elliptical plate 2. During the movement, the optical detector 4 can conveniently scan and detect the upper and lower surfaces of the glass.

[0071] As an embodiment of the present invention, the driving mechanism also includes an elliptical groove 27 and a balancing pin 28. The elliptical groove 27 is opened on the side wall of the elliptical plate 2, and the balancing pin 28 is rotatably connected to the side wall of the mounting frame 3, and the end of the balancing pin 28 extends into the elliptical groove 27; when working, by connecting the balancing pin 28 with the mounting frame 3, when the mounting frame 3 moves with the rotation of the chain 24, one end of the balancing pin 28 will slide along the inner wall of the elliptical groove 27. Through the cooperation between the balancing pin 28 and the elliptical groove 27, a stable guiding support is provided, which is conducive to maintaining the mounting frame 3 to move smoothly along a predetermined elliptical trajectory to avoid the shaking of the mounting frame 3 causing inaccurate detection results. At the same time, the movement of the balancing pin 28 in the elliptical groove 27 can share part of the weight of the mounting frame 3, reduce the burden of the driving mechanism, and extend the service life of the device. The design scheme has a simple structure, is easy to implement, and can effectively improve the accuracy and stability of glass flatness detection.

[0073] Step 1: Limiting the glass: After the sensing unit detects that the glass is located at the test station, it generates detection information and sends it to the control unit. The control unit controls the operation of two dual-function limiting mechanisms to clamp the side wall of the glass to be tested and support the bottom;

[0074] Step 2: Cancel the support of the lifting platform: Move the lifting platform away from under the glass through the control unit to cancel the support of the lifting platform under the glass;

[0075] Step 3: Flatness detection: The control unit controls the two driving mechanisms to operate, driving the mounting frame 3 to move along the elliptical track of the elliptical plate 2, and the optical detector 4 is used to detect the flatness of the upper and lower surfaces of the glass.
