Description
Technical Field
[0001] The present invention relates to the technical field of curved glass detection, and in particular to a 3D curved glass AOI detection light source device and a detection method. Background Art
[0002] The full name of AOI is Automatic Optical Inspection, which is a device for detecting common defects encountered in welding production based on optical principles. AOI is a newly emerging new testing technology, but it has developed rapidly. Many manufacturers have launched AOI testing equipment. When automatically detecting, the machine automatically scans the PCB through a camera, collects images, compares the tested solder joints with the qualified parameters in the database, and through image processing, checks for defects on the PCB and displays / marks the defects through a display or an automatic marker for maintenance personnel to repair. The convenience of this device can be directly applied to the detection of curved screens in mobile phone production, and it can quickly detect the morphological standards of mobile phone curved glass and find the positions where there are breaks or unqualified curvatures.
[0003] However, in the prior art, mobile phone curved glass is not as convenient to clamp as a PCB board. The glass material is often easily damaged by hard clamping, and the curvatures of the curved glass are all on the outer edge of the glass. The clamping device is extremely likely to block the outer edge, resulting in incomplete detection. The manual clamping work also greatly reduces the detection efficiency and is not conducive to the large-scale production of curved screens.
[0004] To solve the above problems, we propose a 3D curved glass AOI detection light source device and a detection method. Summary of the Invention

First telescopic cylinders are fixedly installed at both left and right ends of the detection box and above the box openings. The telescopic ends of the two first telescopic cylinders are arranged downward and are fixedly connected with a lifting plate. Two cylindrical electromagnets are fixedly installed at the lower end of the lifting plate. The two cylindrical electromagnets are arranged corresponding to the distribution of the two adsorption pressing blocks;
[0007] A conveyor belt is arranged at the rear end of the detection box. A receiving block hopper is arranged below the left first telescopic cylinder. A third telescopic cylinder is fixedly installed at the left front position of the front end of the detection box. The telescopic end of the third telescopic cylinder is fixedly connected with the front end of the receiving block hopper. A frame driving mechanism and a camera driving mechanism are arranged in the detection cavity.
[0008] In the above 3D curved glass AOI detection light source device, end plates are fixedly connected to the same sides of the two guide rail plates. A first motor is fixedly installed on the end plate on the right side. The output end of the first motor is coaxially and fixedly connected with a threaded rod. The two threaded rods are connected by belt drive.
[0009] In the above 3D curved glass AOI detection light source device, a glass plate is fixedly connected to the lower ends of the inner walls around the clamping frame. A communication port is opened at the connection position between the device cavity and the detection cavity. A second telescopic cylinder is fixedly installed on the bottom wall of the device cavity. The telescopic end of the second telescopic cylinder is fixedly connected with a top plate. The top plate is located in the communication port and a lamp plate is embedded above it.
[0010] In the above 3D curved glass AOI detection light source device, an auxiliary placement frame is placed on the upper end of the clamping frame. The internal opening size of the auxiliary placement frame is the same as the size of the curved glass. Rubber gaskets are fixedly sleeved on the upper ends of the columnar electromagnets and the lower ends of the adsorption pressing blocks.
[0011] In the above-mentioned 3D curved glass AOI detection light source device, the frame driving mechanism includes two electric telescopic rods arranged oppositely left and right. The electric telescopic rod on the right is fixedly connected to the right inner wall of the detection cavity. A second motor is fixedly installed on the left inner wall of the detection cavity. The output end of the second motor is fixedly connected to the electric telescopic rod on the left. Plug blocks are provided at the telescopic ends of the two electric telescopic rods. The plug block on the left is rectangular and fixedly connected to the electric telescopic rod. The plug block on the right is circular and rotatably connected to the electric telescopic rod. Slots are provided at both left and right ends of the clamping frame. The two slots are rectangular and circular respectively.
[0012] A detection method for a 3D curved glass AOI detection light source device, using the above-mentioned 3D curved glass AOI detection light source device for detection, includes the following steps:
[0013] S1. Move the clamping frame to the right side of the detection box through the first motor. Place the auxiliary placement frame on the upper end of the clamping frame, so that the protrusion at its lower end is stuck into the corresponding notch, and then directly place the curved glass to be detected, so that the position of the curved glass is in the accurate placement position and is supported by two columnar electromagnets below.
[0014] S2. Place the two adsorption pressing blocks into the two cylindrical electromagnets on the right. The cylindrical electromagnets remain magnetized. Drive the adsorption pressing blocks to move down through the first telescopic cylinder. After the rubber gaskets at their lower ends contact the surface of the curved glass, the cylindrical electromagnets are powered off and the columnar electromagnets are powered on to adsorb the two corresponding adsorption pressing blocks above, so as to stably clamp the curved glass state, and then remove the auxiliary placement frame.
[0015] S3. The first motor transports the clamped curved glass through the clamping frame into the detection box. It is lifted by the top plate at the position of the communication port. The clamping frame moves up to the position of the frame driving mechanism, and then is clamped and limited by the plug blocks on the two electric telescopic rods, and is driven by the second motor to rotate at a certain angle, so as to cooperate with the AOI detection camera to effectively perform a comprehensive AOI detection work on the outer curved surface of the curved glass.
[0016] S4. After the detection is completed, the top plate drives the clamping frame to move down, and it is re-clamped between the two moving blocks and is continuously transported to the left by the first motor to the left end of the detection box. The first telescopic cylinder at the left end drives the two cylindrical electromagnets to move down. After contacting the two adsorption pressing blocks, the columnar electromagnets are powered off. The two cylindrical electromagnets at this position are electrified to adsorb the two adsorption pressing blocks and move up. At this time, the detected curved glass can be removed from the clamping frame. The third telescopic cylinder drives the connecting block bucket to move to the lower part of the two adsorption pressing blocks. The cylindrical electromagnets are powered off, so that the two adsorption pressing blocks roll into the conveyor belt through the connecting block bucket and are transported to the right side of the detection box.
[0017] S5. The first motor moves the clamping frame to the right to reset it. Then, the staff can take out the adsorbed pressing block conveyed on the conveyor belt and continue with the steps of S1 to S4 to continuously perform the inspection work on the curved glass.
[0018] Compared with the existing technology, the advantages of the 3D curved glass AOI inspection light source device and inspection method of the present invention are as follows:
[0019] By setting the guide rail plate, clamping frame, columnar electromagnet, adsorbed pressing block, cylindrical electromagnet and conveyor belt, when clamping the curved glass, only need to place the curved glass on the two columnar electromagnets of the clamping frame, and then put the adsorbed pressing block into the cylindrical electromagnet, then the automatic clamping work can be carried out. Clamping with the suction force of the magnet will not block the curved surface at the edge of the curved glass, ensuring effective AOI inspection. Compared with the previous negative pressure adsorption, it is more stable and has lower energy consumption; when disassembling the curved glass, the adsorbed pressing block can be automatically sucked out from the curved glass and sent onto the conveyor belt, and then automatically transported from the disassembly station to the clamping station, so that the adsorbed pressing block can be recycled and there is no need for manual transfer, improving the inspection efficiency of the curved glass.
[0020] By setting the frame driving mechanism, during the inspection process, the curved glass can rotate forward and backward at a certain angle, so as to cooperate with the AOI inspection camera, and can effectively perform the comprehensive AOI inspection work on the outer curved surface of the curved glass. The inspection is more flexible and there is no need for manual adjustment of the position, greatly improving the inspection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode
[0026] The following embodiments are only for illustrative purposes and are not intended to limit the scope of the present invention. Embodiment
[0027] Referring to Figures 1-4 , a 3D curved glass AOI detection light source device and detection method, including a detection box 1. A detection cavity and a device cavity are respectively arranged in the detection box 1 from top to bottom. Box openings communicating with the detection cavity are respectively opened at the left and right ends of the detection box 1. Two guide rail plates 2 are horizontally and fixedly penetrated through the two box openings. The two guide rail plates 2 are arranged at intervals before and after and are both horizontally provided with moving grooves 4 on the opposite sides. Threaded rods 5 are rotatably connected in the two moving grooves 4. Rectangular moving blocks 7 are slidably connected in the two moving grooves 4. The threaded rods 5 penetrate through the corresponding moving blocks 7 and are threadedly connected thereto. End plates 3 are fixedly connected to the same sides of the two guide rail plates 2. A first motor 6 is fixedly installed on the end plate 3 on the right side. The output end of the first motor 6 is coaxially and fixedly connected to one threaded rod 5. The two threaded rods 5 are belt-driven. When the first motor 6 drives one threaded rod 5 to rotate, the other threaded rod 5 also rotates synchronously. The positions where the two guide rail plates 2 extend out of the box opening are respectively the clamping station and the disassembly station during work.
[0028] A clamping frame 8 is arranged between the two moving blocks 7. T-shaped clamping blocks 9 are fixedly connected to the front and rear ends of the clamping frame 8. T-shaped card slots are respectively opened on the opposite sides of the two moving blocks 7. The two T-shaped clamping blocks 9 are clamped in the corresponding T-shaped card slots. The clamping frame 8 can be connected to the two moving blocks 7 through the T-shaped clamping blocks 9 and the T-shaped card slots. Thus, when the threaded rod 5 rotates, the clamping frame 8 can be driven to move horizontally between the two guide rail plates 2. Then, the clamping frame 8 can automatically move back and forth between the clamping station and the disassembly station.
[0029] Fixed blocks 10 are fixedly connected to the inner walls on the left and right sides of the clamping frame 8. Columnar electromagnets 11 are fixedly installed at the upper ends of the two fixed blocks 10. A curved glass is placed on the upper ends of the two columnar electromagnets 11. The curved glass is a curved screen or a curved tempered film used in mobile phone production. Adsorption pressing blocks 12 in columnar shape are adsorbed at the corresponding positions of the two columnar electromagnets 11 above the curved glass. By using the adsorption between the adsorption pressing blocks 12 and the electromagnets, the function of stably clamping the curved glass is achieved. This method will not block the curved surface at the edge of the curved glass, ensuring effective AOI detection. The electromagnetic clamping method is more stable and has lower energy consumption compared with the previous negative pressure adsorption method.
[0030] An auxiliary placement frame 14 is placed on the upper end of the clamping frame 8. The internal opening size of the auxiliary placement frame 14 is the same as the size of the curved glass. The setting of the auxiliary placement frame 14 can facilitate the rapid placement of the curved glass at the accurate clamping position in the clamping station. Rubber gaskets are fixedly sleeved at the upper ends of the columnar electromagnets 11 and the lower ends of the adsorption pressing blocks 12, avoiding direct contact between the columnar electromagnets 11 and the adsorption pressing blocks 12 with the curved glass and protecting the curved glass from being scratched and damaged.
[0031] First telescopic cylinders 15 are fixedly installed at the left and right ends of the detection box 1 and above the box openings. The telescopic ends of the two first telescopic cylinders 15 are arranged downward and fixedly connected with a lifting plate 16. Two cylindrical electromagnets 17 are fixedly installed at the lower end of the lifting plate 16. The distribution of the two cylindrical electromagnets 17 corresponds to the distribution of the two adsorption pressing blocks 12. The cylindrical electromagnets 17 can be used to suck the adsorption pressing blocks 12 into the interior. At the clamping station, after the staff places the curved glass on the two columnar electromagnets 11 and accurately positions it, they only need to put the two adsorption pressing blocks 12 into the two cylindrical electromagnets 17. The cylindrical electromagnets 17 are energized to adsorb, and then the first telescopic cylinder 15 on the right moves it downward to above the clamping frame 8, making the lower ends of the two adsorption pressing blocks 12 close to the surface of the curved glass. At this time, the positions of the adsorption pressing blocks 12 also correspond to the positions of the columnar electromagnets 11. Then the cylindrical electromagnets 17 are powered off and lose the adsorption ability, and the columnar electromagnets 11 are energized to directly adsorb the adsorption pressing blocks 12 in the cylindrical electromagnets 17. The first telescopic cylinder 15 on the right moves upward, completing the clamping work of the curved glass. When the curved glass is detected in the detection box 1 and moved to the disassembly station, the first telescopic cylinder 15 on the left moves downward, making the cylindrical electromagnets 17 close to the two adsorption pressing blocks 12. Then the cylindrical electromagnets 17 are energized and the columnar electromagnets 11 are powered off. The two adsorption pressing blocks 12 are sucked into the cylindrical electromagnets 17 and move upward, and the curved glass can be taken out at the disassembly station.
[0032] A conveyor belt 24 is provided at the rear end of the detection box 1. A receiving block hopper 26 is provided below the first telescopic cylinder 15 on the left side. A third telescopic cylinder 25 is fixedly installed at the left front position of the front end of the detection box 1. The telescopic end of the third telescopic cylinder 25 is fixedly connected to the front end of the receiving block hopper 26. After the cylindrical electromagnet 17 on the left side moves the adsorption pressing block 12 upward, the third telescopic cylinder 25 pushes the receiving block hopper 26 backward until it moves below the cylindrical electromagnet 17. Then, the two cylindrical electromagnets 17 on the left side are powered off, and the adsorption pressing block 12 falls onto the receiving block hopper 26 and rolls backward into the conveyor belt 24, and then is sent to the clamping station by the conveyor belt 24 again, so that the adsorption pressing block 12 can be recycled and there is no need for manual transfer, improving the detection efficiency of the curved glass.
[0033] At the lower ends of the inner walls around the clamping frame 8, a glass plate 13 is fixedly connected in common. A communication port is opened at the connection position between the device cavity and the detection cavity. A second telescopic cylinder 21 is fixedly installed on the bottom wall of the device cavity. The telescopic end of the second telescopic cylinder 21 is fixedly connected to a top plate 22. The top plate 22 is located in the communication port and a lamp panel 23 is embedded above it. When the clamping frame 8 moves to the position of the communication port, the second telescopic cylinder 21 can push the clamping frame 8 upward through the top plate 22. A magnetic strip is embedded on the top plate 22, which can make the contact between the top plate 22 and the clamping frame 8 more stable. The lamp panel 23 serves to provide a bottom light source, making the AOI detection clearer. Supplementary light lamps are installed on the inner walls around the detection cavity to provide supplementary light.
[0034] A frame driving mechanism and an AOI detection camera are provided in the detection cavity. The frame driving mechanism includes two electric telescopic rods 19 arranged opposite to each other left and right. The electric telescopic rod 19 on the right side is fixedly connected to the right inner wall of the detection cavity. A second motor 18 is fixedly installed on the left inner wall of the detection cavity. The output end of the second motor 18 is fixedly connected to the electric telescopic rod 19 on the left side. Plug blocks are provided at the telescopic ends of the two electric telescopic rods 19. The plug block on the left side is rectangular and fixedly connected to the electric telescopic rod 19. The plug block on the right side is circular and rotatably connected to the electric telescopic rod 19. Slots 20 are opened at both the left and right ends of the clamping frame 8. The two slots 20 are rectangular and circular respectively. When the clamping frame 8 is pushed to the position of the frame driving mechanism, the two electric telescopic rods 19 can extend simultaneously, so that the two plug blocks are inserted into the corresponding slots 20 respectively. Then, the second motor 18 can drive the clamping frame 8 and the curved glass above it to rotate at a certain angle through the rectangular plug block.
[0035] Through the forward and backward rotation of the curved glass, the AOI detection camera can effectively perform a comprehensive AOI detection on the outer curved surface of the curved glass. The detection is more flexible and there is no need for manual adjustment of the position, greatly improving the detection efficiency.
[0036] A detection method for a detection light source device of 3D curved glass AOI. Using the above-mentioned detection light source device of 3D curved glass AOI for detection, it includes the following steps:
[0037] S1. Move the clamping frame 8 to the right side of the detection box 1 through the first motor 6, place the auxiliary placement frame 14 on the upper end of the clamping frame 8, and make the protrusion at its lower end snap into the corresponding notch, so as to directly place the curved glass to be detected, make the position of the curved glass in the accurate placement position, and be supported by two columnar electromagnets 11 below;
[0038] S2. Put two adsorption pressing blocks 12 into the two cylindrical electromagnets 17 on the right side. The cylindrical electromagnets 17 remain magnetized. Drive the adsorption pressing blocks 12 to move down through the first telescopic cylinder 15. After the rubber gaskets at their lower ends contact the surface of the curved glass, the cylindrical electromagnets 17 are powered off and the columnar electromagnets 11 are powered on to adsorb the two corresponding adsorption pressing blocks 12 above, so as to stably clamp the curved glass state, and then remove the auxiliary placement frame 14;
[0039] S3. The first motor 6 transports the clamped curved glass through the clamping frame 8 into the detection box 1, and is lifted by the top plate 22 at the position of the communication port. The clamping frame 8 moves up to the position of the frame driving mechanism, and is then clamped and limited by the inserts on the two electric telescopic rods 19, and is driven by the second motor 18 to rotate at a certain angle, so as to cooperate with the AOI detection camera to effectively perform a comprehensive AOI detection work on the outer curved surface of the curved glass;
[0040] S4. After the detection is completed, the top plate 22 drives the clamping frame 8 to move down, and is re-clamped between the two moving blocks 7, and is continuously transported to the left by the first motor 6 to the left end of the detection box 1. The first telescopic cylinder 15 at the left end drives the two cylindrical electromagnets 17 to move down. After contacting the two adsorption pressing blocks 12, the columnar electromagnets 11 are powered off, and the two cylindrical electromagnets 17 at this position are energized to magnetically attract the two adsorption pressing blocks 12 and move up. At this time, the detected curved glass can be removed from the clamping frame 8. The third telescopic cylinder 25 drives the connecting block bucket 26 to move under the two adsorption pressing blocks 12, and the cylindrical electromagnets 17 are powered off, so that the two adsorption pressing blocks 12 roll into the conveyor belt 24 through the connecting block bucket 26 and are transported to the right side of the detection box 1;
[0041] S5. The first motor 6 moves the clamping frame 8 to the right to reset, and the staff can then take out the transported adsorption pressing blocks 12 from the conveyor belt 24 and continue to perform the steps from S1 to S4 to continuously perform the detection work of the curved glass.
[0042] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
