Description

Technical Field

[0001] This utility model relates to the field of glass adhesive sheet inspection technology, specifically a visual inspection device for glass adhesive sheets. Background Technology

[0002] Glass bonding is widely used in industries such as concentrated solar power (CSP), and the installation accuracy of the surface adhesive sheets directly affects structural stability and performance. A glass adhesive sheet visual inspection device is an automated device integrating optical imaging, image processing, motion control, and artificial intelligence technologies. It is specifically designed for high-speed, high-precision automatic inspection and evaluation of the quality, position, and appearance of the bond after glass and other materials are bonded together using adhesive sheets.

[0003] In the visual inspection of glass bonding sheets, manual inspection is inefficient, difficult to match the pace of large-scale production, and the measurement accuracy is greatly affected by human operation, resulting in insufficient consistency and failing to meet the requirements of high-precision inspection. In addition, long-term repetitive manual work is labor-intensive and prone to fatigue errors, which further affects the reliability of inspection. Utility Model Content

[0004] The purpose of this invention is to provide a visual inspection device for glass adhesive sheets to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a visual inspection device for glass bonding sheets, comprising an inspection table, a feeding conveyor, and a discharging conveyor. A feeding conveyor is provided on one side of the outer wall of the inspection table, and a discharging conveyor is provided on the other side. A display is connected to the top of the inspection table via a bracket. A track is installed in the middle of the top of the inspection table, and a worktable is slidably connected to the outer wall of the track. A frame is fixedly connected to the top of the inspection table near the display, and a first guide rail is installed at the top of the frame. A first servo motor is installed in the middle of the outer wall of the first guide rail. A second guide rail is slidably connected inside the first guide rail, and a second servo motor is installed in the middle of the outer wall of the second guide rail. A column is slidably connected inside the second guide rail, and a base is installed on one side of the bottom of the column. A wired laser 3D camera is connected to both sides of the bottom of the base.

[0006] The first guide rail is used to guide the second guide rail to move longitudinally, and the second guide rail is used to guide the column to move laterally. The two work together to realize the X-axis and Y-axis movement of the line laser 3D camera.

[0007] A base plate is provided above the workbench, and a threaded pin is threaded inside the base plate. A threaded hole corresponding to the threaded pin is opened inside the base plate, and a vertical rod is slidably connected to the corner of the base plate.

[0008] The base plate is used to drive the threaded pin to move vertically, and the downward movement of the threaded pin restricts the products on the top of the worktable; the position of the threaded pin is adjusted through the threaded hole to limit products of different shapes on the top of the worktable.

[0009] By adjusting the distance between the rubber pad and the base by turning the threaded pin downwards, products of different thicknesses can be limited.

[0010] Preferably, a loading platform is fixedly connected to one side of the outer wall of the workbench, and a unloading platform is fixedly connected to the other side of the outer wall of the workbench. Both the loading platform and the unloading platform are slidably connected to the track.

[0011] After the glass bonding sheets are bonded, the products are transported to the inspection station via the feeding conveyor. At this time, the feeding station is located below the conveying end of the feeding conveyor. The installed robot moves the products to the feeding station. The robot moves the products from the top of the unloading station to the unloading conveyor. Finally, the unloading conveyor moves the inspected products to the subsequent processes.

[0012] Preferably, a pusher plate is slidably connected inside the top of the loading platform, and an electric telescopic column is installed in the middle of the outer wall of the loading platform. The output end of the electric telescopic column is fixedly connected to the pusher plate. A sliding groove corresponding to the pusher plate is opened in the middle of the top of the loading platform and the workbench.

[0013] By activating the electric telescopic column to extend and drive the pusher plate, the pusher plate moves the product from the loading platform to the worktable; the worktable continues to move along the track closer to the unloading conveyor, and then the electric telescopic column is activated to extend and drive the pusher plate to continue moving, so that the inspected product is moved from the top of the worktable to the unloading platform.

[0014] Preferably, the workbench has support plates on both sides of its outer wall, and the bottom of the support plates is fixedly connected to the top of the testing table. The base plate has transmission rods fixedly connected to both sides of the middle part of its outer wall. The upright has a "T" shaped structure, and the bottom of the threaded pin is connected to a rubber pad.

[0015] The substrate moves down together with the threaded pin. At this time, the substrate is guided to move down smoothly by the upright rod until the rubber pad at the bottom of the threaded pin moves down and fits against the top corner of the product, thus limiting and bonding the glass adhesive sheet.

[0016] Preferably, the support plate has a first straight groove, a first inclined groove, a second straight groove, a second inclined groove, and a third straight groove sequentially formed from right to left inside. The first straight groove, the first inclined groove, the second straight groove, the second inclined groove, and the third straight groove are connected to form a guide groove, and the transmission rod extends into the guide groove.

[0017] The horizontal movement of the worktable will cause the substrate to move horizontally as well. At this time, the transmission rods on both sides of the outer wall of the substrate move along the guide groove inside the support plate. After the transmission rods pass through the first straight groove, the first inclined groove and the second straight groove in sequence, their height changes, causing the substrate to move down along with the threaded pin.

[0018] As can be seen from the above, the visual inspection device for glass bonding sheets provided by this utility model has the following beneficial effects.

[0019] 1. Through fully automated loading, transmission, positioning, inspection, and unloading processes, the time bottleneck of manual operation is completely eliminated. The inspection cycle is far superior to that of humans, perfectly matching the high-speed cycle of large-scale production lines and significantly improving overall production capacity. Non-contact measurement using a line laser 3D camera can acquire sub-millimeter-level high-precision three-dimensional data, accurately quantifying key dimensions such as the contour, height difference, and spacing of the adhesive sheet. The influence of human subjective factors and emotional fluctuations is eliminated, ensuring that the inspection standards for each product are absolutely consistent, and the output results are objective and reliable, greatly improving the consistency of product quality.

[0020] 2. With adjustable threaded pins and rubber pads, product fixtures can be quickly changed, enabling rapid production line changes for products of different shapes and thicknesses, reducing the time and cost of changing tooling; thus solving problems such as fatigue and lack of concentration caused by long-term repetitive manual work, eliminating missed inspections and misjudgments, and ensuring the continuous stability of inspection quality.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-10 The present invention provides a technical solution: a visual inspection device for glass bonding sheets, including an inspection table 1, a feeding conveyor 2 and a discharging conveyor 3. The feeding conveyor 2 is provided on one side of the outer wall of the inspection table 1, and the discharging conveyor 3 is provided on the other side of the outer wall of the inspection table 1. A display 4 is connected to the top of the inspection table 1 through a bracket. A track 5 is installed in the middle of the top of the inspection table 1, and a worktable 6 is slidably connected to the outer wall of the track 5. A frame 7 is fixedly connected to the top of the inspection table 1 near the display 4, and a first guide rail 8 is installed at the top of the frame 7. A first servo motor 9 is installed in the middle of the outer wall of the first guide rail 8. A second guide rail 10 is slidably connected inside the first guide rail 8, and a second servo motor 11 is installed in the middle of the outer wall of the second guide rail 10. A column 12 is slidably connected inside the second guide rail 10, and a base 13 is installed on one side of the bottom end of the column 12. A wired laser 3D camera 14 is connected to both sides of the bottom end of the base 13.

[0034] The first guide rail 8 is used to guide the second guide rail 10 to move longitudinally, and the second guide rail 10 is used to guide the column 12 to move laterally. The two work together to realize the X-axis and Y-axis movement of the line laser 3D camera 14.

[0035] A base plate 18 is provided above the workbench 6, and a threaded pin 19 is threadedly connected inside the base plate 18. A threaded hole 21 corresponding to the threaded pin 19 is opened inside the base plate 18, and a vertical rod 22 is slidably connected to the corner of the base plate 18.

[0036] The base plate 18 is used to drive the threaded pin 19 to move vertically, and the downward movement of the threaded pin 19 restricts the product on the top of the worktable 6; the position of the threaded pin 19 is adjusted through the threaded hole 21 to limit products of different shapes on the top of the worktable 6.

[0037] A loading platform 30 is fixedly connected to one side of the outer wall of the workbench 6, and a unloading platform 15 is fixedly connected to the other side of the outer wall of the workbench 6. Both the loading platform 30 and the unloading platform 15 are slidably connected to the track 5. A pusher plate 16 is slidably connected inside the top of the loading platform 30, and an electric telescopic column 17 is installed in the middle of the outer wall of the loading platform 30. The output end of the electric telescopic column 17 is fixedly connected to the pusher plate 16. A sliding groove corresponding to the pusher plate 16 is opened in the middle of the top of the loading platform 30 and the workbench 6. Support plates 24 are provided on both sides of the outer wall of the workbench 6. The bottom end of the support plate 24 is fixedly connected to the top of the testing table 1. The transmission rods 23 are fixedly connected to both sides of the middle of the outer wall of the base plate 18. The upright rod 22 has a "T" shaped structure. The bottom end of the threaded pin 19 is connected to a rubber pad 20. The support plate 24 has a first straight groove 25, a first inclined groove 26, a second straight groove 27, a second inclined groove 28 and a third straight groove 29 arranged sequentially from right to left. The first straight groove 25, the first inclined groove 26, the second straight groove 27, the second inclined groove 28 and the third straight groove 29 are connected to form a guide groove. The transmission rods 23 extend into the guide groove.

[0038] In practice, the product to be tested is transported to the testing station 1 area via the feeding conveyor 2. At this time, the feeding station 30 is located at the end of the conveyor, and the product is transferred to the feeding station 30 by a robotic arm. Subsequently, the electric telescopic column 17 is activated, driving the pusher plate 16 to precisely push the product from the feeding station 30 onto the worktable 6. The worktable 6 then moves along the track 5 to the testing station below the frame 7;

[0039] See Figure 5 and Figure 7As the worktable 6 moves horizontally, the substrate 18, which is linked to it, moves accordingly. The transmission rods 23 on both sides of the substrate 18 move within specific channels in the support plate 24: first, they maintain their height via the first straight groove 25, then are guided downwards via the first inclined groove 26, and finally enter the second straight groove 27 to maintain a low position. This series of movements allows the substrate 18 to move smoothly downwards under the guidance of the upright rod 22, causing the rubber pad 20 at the bottom of the threaded pin 19 to press against the top corner of the product, completing a flexible and precise fixation of the product. This positioning system has good adaptability. By lifting the threaded pin 19 and re-inserting it into different threaded holes 21 on the substrate 18, the layout of the limiting points can be quickly adjusted to adapt to products of different shapes such as rectangles and triangles. By rotating the threaded pin 19 to adjust the distance between the rubber pad 20 and the base 13, products of different thicknesses can be accommodated.

[0040] See Figure 3 and Figure 4 When the positioned worktable 6 moves below the line laser 3D camera 14, the vision system is activated. By activating the second servo motor 11, the column 12 is driven to move laterally along the second guide rail 10; at the same time, the first servo motor 9 is activated, driving the second guide rail 10 to move longitudinally along the first guide rail 8, thereby realizing the precise movement of the line laser 3D camera 14 in the X / Y plane, which is controlled by the PLC.

[0041] The line laser 3D camera 14 accurately captures the 3D point cloud data of the glass bonding sheet, and its anti-reflective properties ensure the stability and reliability of complex surface inspection. After the inspection data is uploaded to the system, it is visualized and analyzed by the control software on the display 4. This software integrates functions such as user permission management, camera control, multi-point calibration, data analysis, formula management, and alarm log recording, ensuring standardized operation and data traceability.

[0042] The specific operation process includes: system hardware self-test and software initialization; performing camera height calibration and nine-point calibration to establish a precise measurement benchmark; performing scanning path planning and testing formula configuration to support rapid switching of multiple product types; the system automatically completes the measurement of key dimensions such as coordinates, height difference, spacing and diagonal distance of the adhesive sheet, and automatically judges the qualification according to the standard, records the results, and triggers an alarm in case of abnormality.

[0043] After the inspection is completed, the workbench 6 continues to move along the track 5 to the unloading station. At this time, the transmission rod 23 passes through the second inclined groove 28 and the third straight groove 29 in sequence. Under the guidance of the second inclined groove 28, it rises, driving the base plate 18 and the threaded pin 19 to be lifted as a whole. The rubber pad 20 separates from the product and releases the positioning.

[0044] Subsequently, the electric telescopic column 17 extends again, pushing the pusher plate 16 to transfer the product from the worktable 6 to the unloading table 15. The robot then moves the product from the unloading table 15 to the unloading conveyor 3 for transport to the next process.

[0045] Finally, the electric telescopic column 17 retracts, driving the pusher plate 16 back to the loading platform 30 to wait; at the same time, the worktable 6 returns along the track 5 to the loading station, ready to receive the next product, thus forming a continuous automated inspection cycle.

[0046] The fully automated feeding, conveying, positioning, inspection, and unloading process completely eliminates the time bottleneck of manual operation. The inspection cycle is far superior to that of humans, perfectly matching the high-speed cycle of large-scale production lines and significantly improving overall production capacity. The use of a line laser 3D camera 14 for non-contact measurement can acquire sub-millimeter-level high-precision three-dimensional data, accurately quantifying key dimensions such as the contour, height difference, and spacing of the adhesive sheets. It eliminates the influence of subjective factors and emotional fluctuations, ensuring that the inspection standards for each product are absolutely consistent, and the output results are objective and reliable, greatly improving the consistency of product quality.

[0047] With the adjustable threaded pin 19 and rubber pad 20, the product fixture can be quickly changed, enabling rapid production line changeover for products of different shapes and thicknesses, reducing the time and cost of changing tooling; thus solving the problems of fatigue and lack of concentration caused by long-term repetitive manual work, eliminating the resulting missed inspections and misjudgments, and ensuring the continuous stability of inspection quality.

[0048] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
