Description

Technical Field

[0001] This application relates to the field of glass processing technology, and in particular to a glass positioning stage, a glass inspection system, and a glass inspection method. Background Technology

[0002] In automobile manufacturing, after the vehicle glass is manufactured, it needs to undergo quality inspection, such as measuring its outline and dimensions, to determine whether the vehicle glass is up to standard.

[0003] When inspecting the quality of glass, it is first necessary to fix the glass using a positioning platform, and then obtain various parameter information of the glass through various testing equipment. Existing positioning platforms are usually horizontal platforms, and the glass needs to be placed horizontally on the positioning platform when fixing it. Due to the irregular shape of glass, especially windshields, there is a significant risk of deformation when the glass is placed horizontally, which affects the accuracy of the test results. Summary of the Invention

[0004] The purpose of this application is to provide a glass positioning stage, a glass inspection system, and a glass inspection method, which can solve the technical problem of glass being easily deformed during inspection.

[0005] To address the aforementioned technical problems, in a first aspect, this application provides a glass positioning stage, comprising:

[0006] Support frame, used to support the glass;

[0007] The clamping assembly includes a plurality of first fixing clamps disposed on the support frame and spaced apart in the horizontal direction, and a plurality of second fixing clamps disposed on the support frame and spaced apart in the horizontal direction. The first fixing clamps and the second fixing clamps are spaced apart in the vertical direction. The first fixing clamps are movable on the support frame in the vertical direction. A first pressure sensor is provided on the clamping surface of each of the first fixing clamps and the second fixing clamps.

[0008] In one embodiment, the glass positioning stage further includes a centering component, which includes two centering brackets disposed on the support frame. The two centering brackets are spaced apart in the horizontal direction and can move along the horizontal direction on the support frame. Each centering bracket is provided with a second pressure sensor.

[0009] In one embodiment, the support frame includes a first bracket and a second bracket, the first bracket extending along the vertical direction, and the second bracket disposed on the first bracket and extending along the horizontal direction;

[0010] The first fixing clip is slidably disposed on the first bracket, the second fixing clip is fixedly disposed on the first bracket, and the central bracket is slidably disposed on the second bracket.

[0011] In one embodiment, the second bracket is provided with a timing belt and a timing belt handwheel, the timing belt extends along the horizontal direction, and the timing belt handwheel is connected to the timing belt and is used to drive the timing belt to rotate;

[0012] The synchronous belt is provided with two abutment blocks, which are distributed at intervals along the extension direction of the synchronous belt and are located on both sides of the two central supports. The two abutment blocks are used to abut the two central supports respectively. The rotation of the synchronous belt can drive the two abutment blocks to move along the horizontal direction, so that one of the abutment blocks pushes the corresponding central support to move.

[0013] In one embodiment, the support frame further includes a fixing block and a lead screw handle. The fixing block is fixedly disposed on the first bracket and located at the bottom of the second bracket. The lead screw handle is movably mounted on the fixing block and one end abuts against the second bracket. The lead screw handle is used to adjust the installation height of the second bracket in the vertical direction.

[0014] In one embodiment, at least one side of the glass is an arc-shaped edge, and the two ends of the arc-shaped edge form symmetrical support points;

[0015] The glass positioning stage also includes a horizontal positioning component, which includes two horizontal reference plates. The horizontal reference plates are mounted on the second bracket, and each horizontal reference plate is provided with a third pressure sensor. The two support points of the glass can respectively abut against the two horizontal reference plates.

[0016] In one embodiment, the centering bracket is vertically mounted on the horizontal reference plate.

[0017] This application provides a glass positioning stage for clamping and fixing glass, including a support frame and a clamping assembly. On one hand, the clamping assembly includes multiple first fixing clips and multiple second fixing clips disposed on the support frame. The first and second fixing clips are spaced apart vertically, allowing the glass to be placed vertically on the support frame and clamped and fixed by the first and second fixing clips. This arrangement prevents the glass from deforming due to gravity. On the other hand, each of the first and second fixing clips has a first pressure sensor on its clamping surface. When clamping the glass with the first and second fixing clips, the clamping degree can be adjusted according to the pressure value detected by the first pressure sensor. This prevents insufficient clamping force from affecting the fixing effect of the glass, and also prevents excessive clamping force from causing glass deformation or damage, thereby further reducing the risk of glass deformation during clamping. Furthermore, the first fixing clips can move vertically on the support frame, allowing the glass positioning stage to be used to fix different types of glass.

[0018] Secondly, this application provides a glass inspection system, including inspection components and the glass positioning stage described in the first aspect;

[0019] The detection component includes a slide rail, a robotic arm, and a 3D camera. The slide rail is spaced apart from the glass positioning stage and parallel to the support frame. The robotic arm is slidably mounted on the slide rail. The 3D camera is located at the end of the robotic arm away from the slide rail and facing the glass positioning stage.

[0020] In one embodiment, the support frame of the glass positioning stage is provided with reflective points, which are used to receive and reflect the laser emitted by the 3D camera.

[0021] The glass inspection system provided in this application is used for quality inspection of glass. The glass inspection system includes inspection components and a glass positioning stage. On the one hand, by improving the structure of the glass positioning stage, specifically by improving the structure of the support frame and clamping components, the fixing effect of the glass positioning stage on the glass can be effectively improved and the risk of glass deformation and damage can be reduced, thereby effectively improving the accuracy of glass quality inspection. On the other hand, by improving the structure of the inspection components and adopting a non-contact inspection method, the accuracy of data acquisition can be improved, thereby further improving the accuracy of glass quality inspection.

[0022] Thirdly, this application provides a glass testing method, which uses the glass testing system described in the second aspect to test the glass, the testing method comprising:

[0023] The glass inspection system is set up in a dark room;

[0024] The glass is installed on the glass positioning platform and the glass is fixed using a clamping assembly;

[0025] The distance information of each detection point on the glass is obtained using a 3D camera.

[0026] The glass testing method provided in this application is used for quality inspection of glass. On the one hand, by improving the structure of the glass testing system, specifically by optimizing the structure of the glass positioning device and the testing components, the risk of glass deformation and damage can be reduced, and the accuracy of data acquisition can be improved, thereby improving the accuracy of glass quality inspection. On the other hand, by setting the glass testing system in a darkroom, the effectiveness of the glass testing system can be improved and the accuracy of data acquisition can be further improved, thereby further improving the accuracy of glass quality inspection.

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0052] Firstly, this application provides a glass positioning stage, please refer to... Figure 1 The glass positioning stage 100 includes a support frame 1 and a clamping assembly.

[0053] like Figure 1 As shown, the support frame 1 is used to support the glass 200.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, the clamping assembly includes components disposed on the support frame 1 and along the horizontal direction (e.g., Figure 1 A plurality of first fixing clips 21 are spaced apart in the direction shown in the Y-shape, and a plurality of second fixing clips 22 are spaced apart on the support frame 1 in the horizontal direction. The first fixing clips 21 and the second fixing clips 22 are spaced apart in the vertical direction (as shown in the Y-shape). Figure 1 Distributed at intervals (as shown in the Z direction), the first fixing clamp 21 can move vertically on the support frame 1, and the clamping surfaces of both the first fixing clamp 21 and the second fixing clamp 22 are provided with first pressure sensors 211 (e.g., ...). Figure 11 (As shown).

[0055] Multiple first fixing clips 21 and multiple second fixing clips 22 are clamped onto different sides or corners of the glass 200 to fix the glass 200 to the support frame 1. First pressure sensors 211 are provided on the clamping surfaces of the first fixing clips 21 and second fixing clips 22. When the first fixing clips 21 and second fixing clips 22 are clamped onto the glass 200, the clamping pressure between the first fixing clips 21 and second fixing clips 22 and the glass 200 can be obtained through the first pressure sensors 211, thereby adjusting the clamping degree of the first fixing clips 21 and second fixing clips 22. The sensing signal of the first pressure sensor 211 can be fed back to the controller or directly to the user; the specific design can be tailored to the actual situation and is not limited here.

[0056] This application provides a glass positioning stage 100 for clamping and fixing glass 200, including a support frame 1 and a clamping assembly. On one hand, the clamping assembly includes a plurality of first fixing clips 21 and a plurality of second fixing clips 22 disposed on the support frame 1. The first fixing clips 21 and second fixing clips 22 are spaced apart vertically, so that the glass 200 can be placed vertically on the support frame 1 and clamped and fixed by the first fixing clips 21 and second fixing clips 22. This arrangement can prevent the glass 200 from deforming due to gravity. On the other hand, a first pressure sensor 211 is provided on the clamping surface of each of the first fixing clips 21 and second fixing clips 22. When the first and second fixing clamps 21 and 22 clamp the glass 200, the clamping degree of the first fixing clamp 21 and the second fixing clamp 22 can be adjusted according to the pressure value detected by the first pressure sensor 211, so as to avoid insufficient clamping force of the fixing clamps affecting the fixing effect of the glass 200, and to avoid excessive clamping force of the fixing clamps causing deformation or damage to the glass 200, thereby further reducing the risk of deformation of the glass 200 during clamping; on the other hand, the first fixing clamp 21 can move vertically on the support frame 1, so that the glass positioning table 100 can be used to fix different types of glass 200.

[0057] It should be noted that the glass positioning stage 100 can be used as a fixing device to display the glass 200, or it can be used in conjunction with testing equipment to perform quality testing on the glass 200. It has a variety of application scenarios, which will not be elaborated here.

[0058] In the embodiments provided in this application, such as Figure 2 and Figure 3 As shown, the structures of the first fixing clip 21 and the second fixing clip 22 can be the same or different. The first fixing clip 21 and the second fixing clip 22 only need to be able to fix the glass 200 to the support frame 1, and their specific structures are not limited.

[0059] In the embodiments provided in this application, such as Figure 1 and Figure 3As shown, the glass positioning stage 100 also includes a centering component, which includes two centering supports 3 mounted on the support frame 1. The two centering supports 3 are spaced apart in the horizontal direction and can move horizontally on the support frame 1. Each centering support 3 is equipped with a second pressure sensor 221 (e.g., Figure 11 (As shown).

[0060] Two centering brackets 3 are used to clamp the glass 200 horizontally and push it to move, so that the glass 200 can be centered horizontally. The centering brackets 3 are equipped with a second pressure sensor 221 that can detect the holding pressure between the centering brackets 3 and the glass 200 when the centering brackets 3 abut against the side of the glass 200, thereby adjusting the relative position of the centering brackets 3 and the glass 200. The sensing signal from the second pressure sensor 221 can be fed back to the controller or directly to the user; the specific design can be tailored to the actual situation and is not limited here.

[0061] With the above design, on the one hand, the centering bracket 3 can be used to adjust the position of the glass 200 in the horizontal direction so that the glass 200 is horizontally centered, thereby reducing the risk of positioning deformation caused by the deviation of the center of gravity of the glass 200; on the other hand, the positional relationship between the centering bracket 3 and the glass 200 can be adjusted according to the first pressure sensor 211 to avoid deformation of the glass 200 due to compression; furthermore, the centered setting of the glass 200 is conducive to unifying the coordinate reference, thereby facilitating its quality inspection.

[0062] In one embodiment, the glass positioning stage 100 includes a clamping assembly, a centering assembly, and a controller. The controller is connected to a sensing unit (including a first pressure sensor 211 and a second pressure sensor 221). When fixing the glass 200, the centering position of the glass 200 needs to be adjusted first, and then clamped and fixed. Specifically, after the glass 200 is centered and positioned, the controller controls the first fixing clamp 21 and the second fixing clamp 22 to clamp it. During the clamping process, the first pressure sensor 211 determines the clamping status and provides feedback to adjust the clamping force of the first fixing clamp 21 and the second fixing clamp 22 so that the glass 200 can be centered and fixed on the glass positioning stage 100 without bending or deforming.

[0063] In the embodiments provided in this application, such as Figure 4 and Figure 5 As shown, the support frame 1 includes a first bracket 11 and a second bracket 12. The first bracket 11 extends vertically, and the second bracket 12 is disposed on the first bracket 11 and extends horizontally. A first fixing clip 21 is slidably disposed on the first bracket 11, a second fixing clip 22 is fixedly disposed on the first bracket 11, and a central bracket 3 is slidably disposed on the second bracket 12.

[0064] The number of first supports 11 is not unique. Optionally, in one embodiment, such as Figure 4 and Figure 6 As shown, the support frame 1 includes two first supports 11, which are distributed horizontally and arranged in parallel. The clamping assembly includes two first fixing clips 21 and two second fixing clips 22. Each first support 11 is provided with one first fixing clip 21 and one second fixing clip 22.

[0065] When using the glass positioning stage 100 to clamp and fix the glass 200, the installation height of the first fixing clamp 21 and the distance between the two centering brackets 3 can be adjusted according to the size of the glass 200 to be fixed, so that the clamping component and the centering component can clamp different types of glass 200 together.

[0066] With the above design, the support frame 1 has a simple structure, occupies little space, and the positions of the clamping components and the centering components are easy to adjust, making it easy to disassemble and fix the glass 200.

[0067] In the embodiments provided in this application, such as Figure 6 As shown, the support frame 1 also includes a third bracket 13, which extends horizontally and is connected between the two first fixing clips 21. The third bracket 13 is used to balance the installation height of the two first fixing clips 21 to ensure that the installation height of the two first fixing clips 21 can be kept consistent.

[0068] In the embodiments provided in this application, such as Figure 1 , Figure 3 and Figure 4 As shown, the support frame 1 also includes a fourth bracket 14, which is disposed on the first bracket 11 and extends horizontally. The fourth bracket 14 is provided with a support column 15 for supporting the glass 200. The support column 15 is horizontally disposed and perpendicular to the extension direction of the fourth bracket 14. Depending on the shape of the glass 200 to be fixed, the height of the support column 15 can be higher than, lower than or equal to the installation height of the second fixing clip 22.

[0069] The above design can further improve the reliability of the glass 200 positioning device.

[0070] It is understood that in some embodiments, the glass 200 can also be supported by the second fixing clip 22.

[0071] In the embodiments provided in this application, such as Figure 1 As shown, the support frame 1 also includes a base 16 and casters 17 mounted on the base 16. Specifically, the base 16 includes an I-shaped bracket, which is horizontally arranged, with multiple casters 17 mounted below the I-shaped bracket, and a first bracket 11 and a second bracket 12 mounted above the I-shaped bracket.

[0072] The above design improves the practicality and ease of use of the glass positioning platform 100.

[0073] In the embodiments provided in this application, such as Figure 1 , Figure 3 and Figure 4 As shown, the second bracket 12 is equipped with a synchronous belt and a synchronous belt handwheel 4. The synchronous belt extends horizontally, and the synchronous belt handwheel 4 is connected to the synchronous belt and used to drive the synchronous belt to rotate. The synchronous belt is equipped with two abutment blocks, which are distributed at intervals along the extension direction of the synchronous belt and are located on both sides of the two central brackets 3. The two abutment blocks are used to abut the two central brackets 3 respectively. The rotation of the synchronous belt can drive the two abutment blocks to move horizontally, so that one of the abutment blocks pushes the corresponding central bracket 3 to move.

[0074] by Figure 1 and Figure 3 The embodiment shown is illustrated below. The second bracket 12 is provided with a sliding structure, and the centering bracket 3 is slidably mounted on the second bracket 12 via a slider. The centering bracket 3 includes a left centering bracket and a right centering bracket, and the abutting blocks include a left abutting block and a right abutting block. By driving the timing belt handwheel 4 to rotate the timing belt clockwise, the left abutting block abuts against the left centering bracket 3, thereby causing the glass 200 to move to the right; by driving the timing belt handwheel 4 to rotate the timing belt counterclockwise, the right abutting block abuts against the right centering bracket 3, thereby causing the glass 200 to move to the left.

[0075] It is understandable that the two abutment blocks are located on the outside of the two central brackets 3, so they will not interfere with each other during use.

[0076] With the above design, the position of the centering bracket 3 is easy to adjust, and the centering bracket 3 is not easy to fall off the second bracket 12 during the movement, thus ensuring high reliability.

[0077] It is understood that in some embodiments, the centering bracket 3 can also be directly connected to the timing belt through a connecting plate or other structure. The rotation of the timing belt can directly drive the centering bracket 3 to move in the horizontal direction. The specific design can be made according to the actual situation and is not limited here.

[0078] In the embodiments provided in this application, a timing belt handwheel 4 is connected to the timing belt, and the number of timing belt handwheels 4 is not unique.

[0079] Optionally, in one embodiment, such as Figure 1 and Figure 4 As shown, each end of the synchronous belt is connected to a synchronous belt handwheel 4, and both synchronous belt handwheels 4 can be used to control the rotation of the synchronous belt. When adjusting the centering bracket 3, the synchronous belt can be rotated using the synchronous belt handwheel 4 that is close to it, so as to easily observe the position of the abutment block and the centering bracket 3.

[0080] The above design reduces the difficulty of adjusting the position of the centering bracket 3, thereby further improving the ease of use of the glass positioning platform 100.

[0081] In the embodiments provided in this application, the first fixing clip 21 is fixed to the first bracket 11 by an adjustable bolt 23.

[0082] The adjustable bolt 23 has the advantages of firm fixation and precise thread rotation. The first fixing clamp 21 is fixed by the adjustable bolt 23, which has a reliable structure and convenient position adjustment.

[0083] It is understood that in some embodiments, multiple mounting positions may be provided on the first bracket 11, and the first fixing clip 21 may be fixed on the first bracket 11 by a buckle or a fixing collar. The specific design may be made according to the actual situation and is not limited here.

[0084] Glass 200 includes irregularly shaped glass with curved sides. When this irregularly shaped glass contacts the centering bracket 3, it is typically in point-to-point contact. The positional relationship between glass 200 and the centering bracket 3 affects the usability of the centering bracket 3. To improve the practicality and reliability of the centering bracket 3, in the embodiments provided in this application, such as... Figure 1 , Figure 3 and Figure 4 As shown, the support frame 1 also includes a fixing block 51 and a lead screw handle 52. The fixing block 51 is fixedly mounted on the first bracket 11 and located at the bottom of the second bracket 12. The lead screw handle 52 is movably mounted on the fixing block 51 and one end abuts against the second bracket 12. The lead screw handle 52 is used to adjust the installation height of the second bracket 12 in the vertical direction.

[0085] Specifically, the first bracket 11 is provided with a vertically extending groove structure, and the second bracket 12 is slidably mounted on the first bracket 11. The lead screw handle 52 includes a lead screw and a handle connected to the lead screw. The fixing block 51 is provided with a mounting hole, the lead screw passes through the mounting hole and one end extends out of the mounting hole and abuts against the bottom of the second bracket 12. Rotating the lead screw handle 52 can control the extension height of the end of the lead screw abutting against the second bracket 12, thereby adjusting the installation height of the second bracket 12.

[0086] With the above design, on the one hand, the centering bracket 3 is set on the second bracket 12. By adjusting the installation height of the second bracket 12, the centering bracket 3 can be positioned at a suitable height, so that the centering bracket 3 can be well supported on the glass 200, thereby ensuring the effectiveness of the centering bracket 3. On the other hand, the screw handle 52 and the fixing block 51 have a simple structure and are easy to adjust.

[0087] It is understood that in some embodiments, multiple mounting positions may be provided on the first bracket 11, and the second bracket 12 may be connected to the first bracket 11 by means of bolts or sliders or other structures. The specific design can be made according to the actual situation and is not limited here.

[0088] In the embodiments provided in this application, such as Figure 1 , Figure 3 and Figure 4 As shown, at least one side of the glass 200 is arc-shaped, and the two ends of the arc-shaped side form symmetrical support points. The glass positioning stage 100 also includes a horizontal positioning assembly, which includes two horizontal reference plates 6. The horizontal reference plates 6 are mounted on the second bracket 12, and each horizontal reference plate 6 is equipped with a third pressure sensor 61 (e.g., ...). Figure 11 As shown), the two support points of the glass 200 can be supported by the horizontal reference plate 6 respectively.

[0089] On the one hand, the horizontal reference plate 6 and the third pressure sensor 61 are set on the second bracket 12. The horizontal reference plate 6 and the third pressure sensor 61 can be used to determine whether the second bracket 12 is in contact with the glass 200, so as to facilitate the adjustment of the height of the second bracket 12 to ensure the contact effect between the central bracket 3 and the glass 200.

[0090] On the other hand, the two support points of the glass 200 are respectively supported on two horizontal reference plates 6. The pressure value of the two horizontal reference plates 6 can be obtained by the third pressure sensor 61. Based on the obtained pressure value information, it can be determined whether the glass 200 is misaligned. Specifically, when the pressure on one side of the horizontal reference plate 6 is greater, that is, when the glass 200 is offset and tilted relative to this side, it is necessary to use the centering bracket 3 to push the glass 200 to the opposite side so that the glass 200 can be centered.

[0091] The sensing signal of the third pressure sensor 61 can be fed back to the controller or directly to the user. The specific design can be made according to the actual situation and is not limited here.

[0092] The above design helps to reduce the difficulty of adjusting the height of the second bracket 12 and the centering bracket 3, and improves the use effect and centering positioning accuracy of the centering bracket 3, thereby improving the reliability and ease of use of the glass 200 positioning device.

[0093] Furthermore, the centering bracket 3 is vertically installed on the horizontal reference plate 6.

[0094] Specifically, the horizontal reference plate 6 is horizontally set on the second bracket 12 and slidably connected to the second bracket 12. The central bracket 3 is installed on the side of the horizontal reference plate 6 away from the second bracket 12 and perpendicular to the second bracket 12. The central bracket 3 and the horizontal reference plate 6 respectively contact the adjacent two sides of the glass 200.

[0095] With the above design, the centering bracket 3 and the horizontal reference plate 6 work well together. When adjusting the centering bracket 3, the pressure value information on the horizontal reference plate 6 can be obtained in real time, so that the glass 200 positioning can be completed quickly and accurately.

[0096] It is understood that in some embodiments, positioning marks are provided on the middle part of the glass 200 and the glass positioning platform 100. When adjusting the position of the glass 200 using the centering bracket 3, it can be directly determined whether the glass 200 is centered based on the positioning marks.

[0097] In summary, the glass positioning stage 100 provided in this application can be used to clamp and fix the glass 200. By improving the structure of the support frame 1 and the clamping component, the fixing effect of the glass 200 can be improved and the risk of deformation and damage of the glass 200 can be reduced. Furthermore, by setting the centering component, the centering effect of the glass 200 can be improved, thereby reducing the risk of positioning deformation of the glass 200 due to the deviation of the center of gravity. Moreover, by setting the horizontal positioning component, the positioning accuracy and positioning speed of the centering component can be further improved.

[0098] Secondly, this application provides a glass inspection system, including an inspection component 300 and the glass positioning stage 100 mentioned in the first aspect.

[0099] like Figure 7 , Figure 8 and Figure 9 As shown, the detection component 300 includes a slide rail 71, a robotic arm 72, and a 3D camera 73. The slide rail 71 is spaced apart from the glass positioning stage 100 and parallel to the support frame 1. The robotic arm 72 is slidably mounted on the slide rail 71. The 3D camera 73 is mounted at the end of the robotic arm 72 away from the slide rail 71 and facing the glass positioning stage 100.

[0100] The glass positioning stage 100 includes a support frame 1 and a clamping assembly, the specific structure of which is as described in the first aspect and will not be repeated here.

[0101] The glass inspection system described above can be used to inspect the quality of glass 200. The glass positioning stage 100 is used to fix the glass 200, and the inspection component 300 is used to acquire distance information of multiple points on the glass 200. Based on the distance information acquired by the inspection component 300, it can be determined whether the shape and structure of the glass 200 meet the design requirements.

[0102] The detection component 300 uses triangulation to measure distance. Specifically, the 3D camera 73 includes a laser generator and an image sensor. The laser generator emits a detection laser towards the glass 200. After the laser shines on the surface of the glass 200 at a certain incident angle, it can be reflected and scattered. This part of the reflected and scattered laser converges to form an image and is imaged on the image sensor in the form of a light spot. When the 3D camera 73 and the glass 200 move relative to each other, the light spot on the image sensor moves, and the magnitude of the light spot displacement corresponds to the relative movement distance between the 3D camera 73 and the glass 200. Thus, the position information of each detection point of the glass 200 in the coordinate system established with the 3D camera can be obtained from the light spot position information, and the shape and structure of the glass 200 can be calculated.

[0103] It should be noted that the 3D camera 73 employs non-contact detection. In a dark environment, the 3D camera 73 can better capture the surface contour data points of the glass 200. Therefore, to ensure the detection accuracy and performance of the detection component 300, such as... Figure 10 As shown, the glass inspection system described above can be used in a darkroom. Additionally, the glass inspection system includes a control module into which programmed data is input, enabling automatic control of the movement trajectory of the 3D camera 73.

[0104] The glass inspection system provided in this application is used for quality inspection of glass 200. The glass inspection system includes an inspection component 300 and a glass positioning stage 100. On the one hand, by improving the structure of the glass positioning stage 100, specifically by improving the structure of the support frame 1 and the clamping component, the fixing effect of the glass positioning stage 100 on the glass 200 can be effectively improved and the risk of deformation and damage to the glass 200 can be reduced, thereby effectively improving the accuracy of glass 200 quality inspection. On the other hand, by improving the structure of the inspection component 300 and adopting a non-contact inspection method, the accuracy of data acquisition can be improved, thereby further improving the accuracy of glass 200 quality inspection.

[0105] In the embodiments provided in this application, the slide rail 71 is a magnetic levitation guide rail, and the robotic arm 72 is a six-axis robotic arm. The magnetic levitation guide rail extends horizontally and can drive the six-axis robotic arm and the 3D camera 73 to move rapidly horizontally. The six-axis robotic arm can drive the 3D camera 73 to move freely in all directions within space.

[0106] By adopting the above design, when the 3D camera 73 is driven by the magnetic levitation guide rail and the six-axis manipulator, it can be ensured that the 3D camera 73 is always perpendicular to the glass 200 curved surface for detection. During the measurement process, there is no need to repeatedly fit the detection coordinates, which can further improve the accuracy of detection data, reduce the time spent on data processing, and effectively improve the reliability and efficiency of detection.

[0107] In the embodiments provided in this application, the support frame 1 of the glass positioning stage 100 is provided with reflective points, which are used to receive and reflect the laser emitted by the 3D camera 73.

[0108] Optionally, in one embodiment, the portion of the support frame 1 not obscured by the glass 200 is provided with a plurality of irregular reflective points, with an interval of 50mm-200mm between adjacent reflective points.

[0109] The reflective points can help the 3D camera 73 establish a unified spatial coordinate system, so that the glass positioning stage 100 and the detection component 300 are aligned, thereby further improving the detection speed and detection accuracy.

[0110] It should be noted that the detection component 300, driven by the glass design data stored in the computer and the programmable motion trajectory, can first judge the reflective points, and after establishing the coordinate system, automatically adjust and optimize the detection coordinates and motion path.

[0111] Thirdly, this application provides a glass testing method, which uses the glass testing system described in the second aspect to test the glass 200, such as... Figure 8 , Figure 9 and Figure 12 As shown, the detection method includes:

[0112] S1. Set up the glass inspection system in a dark room.

[0113] Depending on the testing requirements, a light source or a light shield can be installed in the darkroom.

[0114] S2. Install the glass 200 on the glass positioning platform 100 and fix the glass 200 using the clamping assembly.

[0115] After installing the glass 200 on the glass positioning platform 100, it is necessary to adjust the horizontal position of the glass 200. After the glass 200 is centered, the clamping assembly is used to clamp and fix the glass 200.

[0116] S3. Use 3D camera 73 to obtain distance information of each detection point on glass 200.

[0117] Specifically, the distance information of each point on the glass 200 is obtained by using the triangulation method, and the shape and structure of the glass 200 are analyzed.

[0118] The glass testing method provided in this application is used to perform quality inspection on glass 200. On the one hand, by improving the structure of the glass testing system, specifically by optimizing the structure of the glass 200 positioning device and the testing component 300, the risk of glass 200 deformation and damage can be reduced, and the accuracy of data acquisition can be improved, thereby improving the accuracy of glass 200 quality inspection. On the other hand, by setting the glass testing system in a darkroom, the effectiveness of the glass testing system can be improved and the accuracy of data acquisition can be further improved, thereby further improving the accuracy of glass 200 quality inspection.

[0119] In the embodiments provided in this application, a light source is provided in the darkroom, and the brightness of the light source can be adjusted according to the different colors of the glass 200. Specifically, when the glass 200 is darker in color and has lower light transmittance, the brightness of the light source can be relatively increased; when the glass 200 is lighter in color and has higher light transmittance, the brightness of the light source can be relatively decreased, so as to further improve the detection accuracy of the 3D camera 73.

[0120] In some embodiments, when the shading level of the darkroom is low, a curtain can be set up in the darkroom to illuminate the glass inspection system in order to further optimize the darkroom environment and thereby further improve the inspection accuracy of the glass inspection system.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
