Description

Technical Field

[0002] Tempered glass for mobile phones is widely used in the field of smart electronic displays, and product quality is receiving increasing attention in manufacturing. Detection of defects in the appearance of tempered glass for mobile phones is a necessary step in its manufacturing process.

[0003] Currently, the inspection of transparent glass, a highly repetitive and intelligent task, is still predominantly performed by the human eye. However, in actual inspection processes, workers cannot consistently and reliably perform this task with the naked eye. This results in poor reliability, low efficiency, and a high degree of subjectivity, leading to frequent false positives and missed positives. Furthermore, workers are prone to occupational diseases (eye diseases), posing significant health risks. More importantly, due to the transparent and highly reflective nature of transparent glass, even conventional visual inspection methods cannot achieve comprehensive, accurate, and detailed detection of all types of defects. Incomplete detection and low efficiency are technical problems inherent in existing glass defect inspection equipment. Therefore, there is an urgent need to develop a high-efficiency inspection device for tempered glass to meet the rapid development needs of the glass and 3C electronics industries.

Detailed Implementation

[0035] 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.

[0036] See Figure 1-Figure 4As shown, it includes an AOI inspection machine 2, with a loading machine 1 and a unloading machine 3 connected to its two sides respectively. The AOI inspection machine 2 includes an inspection frame 2-6, on which a precision positioning platform 2-2 for secondary positioning of the glass is installed. An inspection carrier 2-5 is installed on the side of the precision positioning platform 2-2, and a vision inspection device 2-3 is mounted on top of the inspection carrier 2-5. An unloading module 2-4 is installed in front of the inspection carrier 2-5, and the unloading module 2-4 is mounted between the AOI inspection machine 2 and the unloading machine 3. A loading module 2-1 is installed behind the precision positioning platform 2-2, and the loading module 2-1 is mounted between the AOI inspection machine 2 and the loading machine 1.

[0037] See Figures 1-9 As shown, the precision positioning platform 2-2 includes a connected base and a platform plate. Two sets of positioning components are installed on the base, with an included angle of 90° between the two sets of positioning components. Each set of positioning components includes two synchronous pulleys 2-2-5 located on the base. A flat belt 2-2-6 is installed on the two synchronous pulleys 2-2-5. Two linear guides 2-2-2 are installed on the base between the flat belts 2-2-6. Each linear guide 2-2-2 has a slider slidably installed on it. One slider is connected to the upper half of the flat belt 2-2-6, and the other slider is connected to the lower half of the flat belt 2-2-6. Multiple positioning posts 2-2-1 are vertically arranged on the slider of each linear guide 2-2-2. Multiple movable slots are opened on the platform plate, and the positioning posts 2-2-1 are all located in the movable slots. A servo motor 2-2-4 is installed on the base. The shaft of the servo motor 2-2-4 is connected to one of its synchronous pulleys 2-2-5 through a coupling 2-2-3.

[0038] As an optimized solution of this utility model, the servo motor 2-2-4 drives the synchronous wheel 2-2-5 and the flat belt 2-2-6 to rotate. When the flat belt 2-2-6 rotates, the upper and lower halves move in opposite directions, thereby driving the two sliders to move in opposite directions. This, in turn, drives the two sets of positioning columns 2-2-1 to move towards each other or move relative to each other, thereby clamping the glass plate to be tested on the platform plate towards the center for positioning. The two sets of positioning components work simultaneously to perform secondary positioning of the glass plate, thereby ensuring that the glass plate is located in the center.

[0039] See Figures 1-6As shown, the feeding module 2-1 includes several fixed profiles 2-1-3 vertically mounted on the inspection frame 2-6. An X-axis module 2-1-6 is mounted on the fixed profiles 2-1-3. A servo motor 2-1-2 for driving is mounted on one end of the X-axis module 2-1-6. A tank chain 2-1-1 is connected to the sliding block on the X-axis module 2-1-6, and a Z-axis cylinder 2-1-5 is mounted below the sliding block. A non-marking suction cup 2-1-4 for gripping materials is connected below the Z-axis cylinder 2-1-5.

[0040] As an optimized solution of this utility model, the X-axis module 2-1-6 drives the Z-axis cylinder 2-1-5 and the non-marking suction cup 2-1-4 to move laterally. At the same time, the extension and retraction of the Z-axis cylinder 2-1-5 can drive the non-marking suction cup 2-1-4 to rise and fall, pick up and place the glass plate, thereby realizing the acquisition of the glass plate from the loading machine 1 and placing it on the precision positioning platform 2-2.

[0041] See Figures 1-11 As shown, the unloading module 2-4 includes several fixed profiles 2-4-4 vertically mounted on the inspection frame 2-6. An X-axis module 2-4-2 is mounted on the fixed profiles 2-4-4. One end of the X-axis module 2-4-2 is equipped with a servo motor 2-4-3 for driving its operation. A tank track 2-4-1 is connected to the slider on the X-axis module 2-4-2. A bracket is mounted on the slider, and the slider is connected to the middle of the bracket. Linear rails 2-4-5 are mounted at both ends of the rear side of the bracket. Sliding blocks are slidably mounted on the linear rails 2-4-5. A segmented cylinder 2-4-8 for driving the movement of the sliding block is mounted on the bracket on the side of each sliding block. A Z-axis cylinder 2-4-7 is mounted on the sliding block. A support plate is connected to the drive end of the Z-axis cylinder 2-4-7. Several non-marking suction cups 2-4-6 are connected to the head of the support plate.

[0042] As an optimized solution of this utility model, an X-axis module 2-4-2 is set to drive the support to move, and a Z-axis cylinder 2-4-7 can drive the non-marking suction cup 2-4-6 to rise and fall, thereby gripping and placing materials. With the setting of two sets of non-marking suction cups 2-4-6, during operation, one set can grip the glass plate on the precision positioning platform 2-2, and the other set can grip the glass plate that has been inspected on the inspection carrier 2-5. With the drive of the X-axis module 2-4-2, the glass plate that has been inspected on the inspection carrier 2-5 can be moved to the unloading machine 3, and at the same time, the glass plate on the precision positioning platform 2-2 can be moved to the inspection carrier 2-5. The loading and unloading of the inspection carrier 2-5 can be completed in one operation. Moreover, the two sets of non-marking suction cups 2-4-6 installed on the support can be independently fine-tuned under the action of the segmented cylinder 2-4-8, which has good flexibility.

[0043] See Figures 1-12 As shown, the visual inspection device 2-3 includes a mounting bracket 2-3-1 mounted on the inspection frame 2-6, and a visual inspection module 2-3-2 is mounted on the top of the mounting bracket 2-3-1 facing downwards;

[0044] The detection carrier 2-5 includes an X-axis module 3 2-5-3, on which an upward-mounted suction cup carrier 2-5-2 is driven and mounted. The suction cup carrier 2-5-2 is equipped with two sets of separately controlled suction cups, and a tank chain 3 2-5-1 is connected to the slider of the X-axis module 3 2-5-3.

[0045] As an optimized solution of this utility model, a suction cup carrier 2-5-2 is used to adsorb the glass plate to ensure that the glass plate does not slip during movement and inspection. The X-axis module 2-5-3 can drive the suction cup carrier 2-5-2 and the glass plate to move. The vision inspection module 2-3-2 can acquire images of the glass plate surface to detect the quality of the glass plate. The two sets of suction cups of the suction cup carrier 2-5-2 work alternately. During visual recognition, only one set of suction cups is adsorbed in a single image, which can reduce the shadows generated while ensuring stable adsorption of the glass plate.

[0046] See Figure 1-Figure 2 As shown, the feeding machine 1 includes a feeding frame 1-8, on which a conveyor line 1-5 for conveying trays is installed. At both ends of the conveyor line 1-5, a set of discharge baffles for limiting the trays are vertically installed. The blocking height of the discharge baffles is higher than the height of a single-layer tray. On the lower sides of one set of discharge baffles, opposing first pallet insertion cylinders left 1-1 and right 1-3 are installed. On the lower sides of the other set of discharge baffles, opposing second pallet insertion cylinders right 1-4 and left 1-7 are installed. The telescopic heads of the left 1-1 pallet insertion cylinder, the right 1-3 first pallet insertion cylinder, the right 1-4 second pallet insertion cylinder, and the left 1-7 second pallet insertion cylinder are all connected with "L"-shaped support heads. The center positions of the two sets of discharge baffles are respectively provided with empty top lifting plate 1-2 and full top lifting plate 1-9. Empty top lifting plate 1-2 and full top lifting plate 1-9 are located below the conveying flow line 1-5. Lifting heads 1-10 are installed on both sides of empty top lifting plate 1-2 and full top lifting plate 1-9 respectively. Lifting cylinders 1-6 are installed at the bottom of full top lifting plate 1-9 and empty top lifting plate 1-2.

[0047] The unloading machine 3 includes an unloading frame 3-6, on which a second conveyor line 3-8 for conveying trays is installed. At both ends of the second conveyor line 3-8, a set of unloading baffles for limiting the trays are vertically installed. The blocking height of the unloading baffles is higher than the height of a single-layer tray. On the lower sides of one set of unloading baffles, opposing third pallet insertion cylinders 3-1 (left) and 3-7 (right) are installed. On the lower sides of the other set of unloading baffles, opposing fourth pallet insertion cylinders 3-5 (right) and 3-5 (left) are installed. -4, the telescopic heads of the third pallet insertion cylinder left 3-1, the third pallet insertion cylinder right 3-7, the fourth pallet insertion cylinder right 3-5, and the fourth pallet insertion cylinder left 3-4 are all connected with "L"-shaped support heads. The center positions of the two sets of discharge baffles are respectively provided with empty top lifting plate 2 3-3 and full top lifting plate 2 3-2. Both empty top lifting plate 2 3-3 and full top lifting plate 2 3-2 are located below the conveying flow line 2 3-8. Top plates are installed on both sides of empty top lifting plate 2 3-3 and full top lifting plate 2 3-2. Cylinders are installed at the bottom of full top lifting plate 2 3-2 and empty top lifting plate 2 3-3.

[0048] As an optimized solution of this utility model, a conveyor flow line 1-5 is set up to convey the first-layer tray above it backwards, while the upper tray is blocked by the discharge baffle. Once the tray reaches the middle of the conveyor flow line 1-5, feeding can begin. Empty trays can then reach the rear end via the conveyor flow line 1-5. The lifting cylinder 1-6 is activated, raising the full lifting plate 1-9, thereby using the lifting head 1-10 to lift the empty tray upwards to the discharge end. In the material baffle, the second pallet insertion cylinder 1-7 is activated again, and the support head of the cylinder supports the empty tray above. The lifting cylinder 1-6 can then be retracted until the next empty tray arrives. Repeat the above operation to stack the empty trays. The structure of the unloading machine 3 is the same as that of the loading machine 1. The difference is that when the unloading machine 3 is used, it puts in an empty tray. The conveyor line 3-8 sends the empty tray to the middle for loading, and then conveys it to the tail end to stack the full trays.

[0049] The usage process of this utility model is as follows: Figure 2As shown, the loading machine 1 and unloading machine 3 are respectively divided into station A (empty tray buffer loading station), station B (full tray buffer unloading station), station C (full tray buffer loading station), and station D (empty tray buffer unloading station). First, the tray filled with glass plates to be tested is placed into station C, and the empty tray is placed into station A. Conveyor flow line 2 3-8 sends the empty tray to the middle, while conveyor flow line 1-5 sends the bottom full tray to the middle. The loading module 2-1 starts working, and the non-marking suction cup 2-1-4 moves above the glass plate, adsorbs the glass plate, and sends it to the precision positioning platform 2-2. The precision positioning platform 2-2 starts working, pushing the glass plate towards the center from the X and Y axes respectively, so that its position reaches the center. Then the unloading module... 2-4 begins operation, adsorbing the glass plate on the precision positioning platform 2-2 and placing it on the suction cup carrier 2-5-2. The glass plate then begins to move, and the vision inspection module 2-3-2 starts working. During the movement of the glass plate, the vision inspection module 2-3-2 acquires multiple sets of image data and comprehensively analyzes them to determine if there are any defects in the glass plate. During the inspection process, the loading module 2-1 also sends the glass plate back to the precision positioning platform 2-2 for positioning. Then, the unloading module 2-4 starts again, adsorbing the glass plate on the precision positioning platform 2-2 and simultaneously adsorbing the glass plate that has been inspected in the inspection carrier 2-5. The glass plate on the precision positioning platform 2-2 is then sent to the inspection carrier 2-5, while the inspected glass plate is sent to the unloading machine 3 and loaded into the tray. The equipment operates sequentially until the inspection is completed.
