[0002] PCB, also known as printed circuit board, is a provider of electrical connections for electronic components. The design of PCB mainly involves layout design. The main advantages of using PCB are that it greatly reduces wiring and assembly errors, improves automation and production efficiency.

[0003] Currently, high-end PCBs and packaging substrates have increasingly finer circuit lines (up to 8µm). Visual inspection (AOI) of the etched circuit lines typically uses single-sided black-and-white AOI (primarily by companies like KLA, Condyle, and Giagavis). The workflow is: AOI scanning inspection – defect points are transmitted to the VRS inspection station for image capture and manual judgment. Three problems plague users: 1. High manpower requirements; 2. Quality risks associated with purely manual judgment; 3. Quality risks associated with manual product handling. Utility Model Content

[0047] In one embodiment of this utility model, such as Figures 1-9As shown, an AI vision inspection machine is provided, including a frame 1, a lower vision mechanism 2, a glass inspection platform 3, a glass top cover 4, a glass top cover moving mechanism 5, an upper vision mechanism 6, a material inlet mechanism 7, a board picking mechanism 8, and a material outlet mechanism 9. The lower vision mechanism 2 is connected to the frame 1, and the glass inspection platform 3 is connected to the frame 1 and positioned above the lower vision mechanism 2. The glass top cover 4 is connected to the glass top cover moving mechanism 5 and positioned above the glass inspection platform 3. The glass top cover 4 and the glass inspection platform 3 form an inspection channel, through which PCBs are inspected. Furthermore, the glass inspection platform 3 and the glass top cover 4 can flatten protruding PCBs, resulting in better imaging and improved inspection accuracy. The glass top cover moving mechanism 5 is connected to the frame 1, and the upper vision mechanism 6 is connected to the top of the frame 1 and positioned above the glass top cover 4. The material inlet mechanism 7 is located on one side of the frame 1, the material outlet mechanism is located on the other side of the frame 1, and the board picking mechanism 8 is connected to the top of the frame 1 and positioned on one side of the upper vision mechanism 6.

[0048] like Figure 1 and 3 As shown, the lower vision mechanism 2 includes a lower vision moving component 21 and a lower vision detection component 22. The lower vision moving component 21 is connected to the frame 1, and the lower vision detection component 22 is connected to the lower vision moving component 21 and is located below the glass inspection platform 3.

[0049] like Figures 4-5 As shown, the upper vision mechanism 6 includes an upper vision moving component 61 and an upper vision detection component 62. The upper vision moving component 61 is connected to the frame 1, and the upper vision detection component 62 is connected to the upper vision moving component 61.

[0050] The AI ​​visual inspection machine provided in this application enables collaboration between various institutions to automatically complete inspection work, reducing manpower, avoiding the risks of human error and product contact, and improving inspection accuracy and efficiency.

[0051] In another embodiment of this utility model, such as Figure 3As shown, the lower vision moving component 21 includes a lower fixed base 211, a lower moving slide rail 212, a lower moving slider 213, a lower moving X-axis module 214, a lower moving slide block 215, a lower moving Y-axis base 216, and a lower moving Y-axis module 217. The lower fixed base 211 is fixedly connected to the frame 1, the lower moving slide rail 212 is fixedly connected to the lower fixed base 211, the lower moving slider 213 is slidably connected to the lower moving slide rail 212, the lower moving X-axis module 214 is fixedly connected to the lower fixed base 211 and is disposed on one side of the lower moving slide rail 212, the lower moving slide block 215 is fixedly connected to the lower moving X-axis module 214, the lower moving Y-axis base 216, and the lower moving slider 213 respectively, the bottom end of the lower moving Y-axis base 216 is fixedly connected to the lower moving slider 213, the lower moving Y-axis module 217 is fixedly connected to the lower moving Y-axis base 216, and the lower vision detection component 22 is fixedly connected to the lower moving Y-axis module 217. The lower fixed base 211 is fixedly connected to the frame 1 as a basic component, providing a stable mounting base for the entire lower vision moving assembly 21. The lower moving slide rail 212 is fixed to this lower fixed base 211, and the lower moving slider 213 can slide along the lower moving slide rail 212, which provides a directional motion basis for the movement of subsequent components.

[0052] The lower moving X-axis module 214 is fixed on the lower fixed base 211, which is also fixed to the frame 1, and is located on one side of the lower moving slide rail 212. The lower moving slide block 215 is fixedly connected to the lower moving X-axis module 214, the lower moving Y-axis base 216, and the lower moving slider 213. When the lower moving X-axis module 214 is working, it can drive the lower moving slide block 215 to move in the X-axis direction. Since the lower moving slide block 215 is connected to the lower moving slider 213, and the lower moving slider 213 cooperates with the lower moving slide rail 212, the lower moving slider 213 will slide on the slide rail when moving in the X-axis direction to ensure the stability and accuracy of the movement.

[0053] The bottom end of the lower moving Y-axis base 216 is fixedly connected to the lower moving slider 213, and the lower moving Y-axis module 217 is fixedly connected to the lower moving Y-axis base 216. After the lower moving X-axis module 214 moves the lower moving slide 215 to the designated position, the lower moving Y-axis module 217 can drive the lower moving Y-axis base 216 and the lower vision detection component 22 connected thereto to move in the Y-axis direction.

[0054] In this way, through the coordinated operation of the lower moving X-axis module 214 and the lower moving Y-axis module 217, the lower vision inspection component 22 can move to different positions within a plane (XY plane) to perform vision inspection tasks at different positions. The cooperation between the lower moving slider 213 and the lower moving slide rail 212 ensures the smoothness and accuracy of the entire movement process, enabling the lower vision inspection component 22 to accurately reach the designated inspection position and complete the corresponding inspection work.

[0055] In another embodiment of this utility model, such as Figure 3 As shown, the lower vision inspection assembly 22 includes a lower vision inspection fixture 221 and a lower vision inspection camera 222. The lower vision inspection fixture 221 is fixedly connected to the lower moving Y-axis module 217, and the lower vision inspection camera 222 is fixedly connected to the lower vision inspection fixture 221. The lower vision inspection fixture 221 serves as a connecting component and is fixedly connected to the lower moving Y-axis module 217. When different positions need to be inspected, the lower moving Y-axis module 217 can move in the Y-axis direction, causing the lower vision inspection fixture 221 to move in the Y-axis direction. At the same time, the lower moving X-axis module 214 can move in the X-axis direction. Since the lower moving Y-axis module 217 is fixed on the lower moving slide 215 connected to the lower moving X-axis module 214, the lower moving X-axis module 214 can also cause the lower vision inspection fixture 221 to move in the X-axis direction.

[0056] The lower vision inspection camera 222 is fixedly connected to the lower vision inspection fixture 221. As the lower vision inspection fixture 221 moves, the lower vision inspection camera 222 also moves. Once the lower vision inspection fixture 221 is moved to the designated position, the lower vision inspection camera 222 can perform visual inspection of the object at that position.

[0057] The lower vision inspection camera 222 passes through the glass inspection platform 3 and acquires image information of the bottom of the PCB on the glass inspection platform 3. Using its own image recognition and processing technology, it analyzes and judges the shape, size, position, surface features, etc. of the object, thereby realizing the inspection of the PCB surface.

[0058] In another embodiment of this utility model, such as Figures 4-5As shown, the upper vision moving component 61 includes an upper fixed base 611, an upper moving slide rail 612, an upper moving slider 613, an upper moving X-axis module 614, an upper moving slide block 615, an upper moving Y-axis base 616, and an upper moving Y-axis module 617. The upper fixed base 611 is fixedly connected to the frame 1. The upper moving slide rail 612 is fixedly connected to the upper fixed base 611. The upper moving slider 613 is slidably connected to the upper moving slide rail 612. The upper moving X-axis module 614 is fixedly connected to the upper fixed base 611 and is disposed on one side of the upper moving slide rail 612. The upper moving slide block 615 is fixedly connected to the upper moving X-axis module 614, the upper moving Y-axis base 616, and the upper moving slider 613 respectively. The top of the upper moving Y-axis base 616 is fixedly connected to the upper moving slider 613. The upper moving Y-axis module 617 is fixedly connected to the upper moving Y-axis base 616. The upper vision detection component 62 is fixedly connected to the upper moving Y-axis module 617. The upper fixed base 611 serves as a basic component, firmly fixedly connected to the frame 1, providing stable support and mounting reference for the entire upper vision moving assembly 61. The upper moving slide rail 612 is fixedly mounted on the upper fixed base 611, and the upper moving slider 613 forms a sliding connection with the upper moving slide rail 612, allowing the upper moving slider 613 to slide smoothly along the upper moving slide rail 612, which provides basic motion guidance for the movement of subsequent components.

[0059] The upper moving X-axis module 614 is fixedly connected to the upper fixed base 611 and located on one side of the upper moving slide rail 612. The upper moving slide block 615 is fixedly connected to the upper moving X-axis module 614, the upper moving Y-axis base 616, and the upper moving slider 613. When the upper moving X-axis module 614 starts working, it drives the upper moving slide block 615 to move in the X-axis direction. Since the upper moving slide block 615 and the upper moving slider 613 are fixedly connected, and the upper moving slider 613 cooperates with the upper moving slide rail 612, the upper moving slider 613 will slide synchronously on the slide rail during the movement in the X-axis direction to ensure the stability and accuracy of the movement.

[0060] The top of the upper moving Y-axis base 616 is fixedly connected to the upper moving slider 613, and the upper moving Y-axis module 617 is fixedly mounted on the upper moving Y-axis base 616. When the upper moving X-axis module 614 moves the upper moving slide 615 to the specified X-axis position, the upper moving Y-axis module 617 starts to work, and it can drive the upper moving Y-axis base 616 and the upper vision detection component 62 connected thereto to move in the Y-axis direction.

[0061] Through the coordinated operation of the upper moving X-axis module 614 and the upper moving Y-axis module 617, the upper vision detection component 62 can freely move to different positions within a plane (XY plane). The cooperation between the upper moving slider 613 and the upper moving slide rail 612 ensures the smoothness and high precision of the entire movement process, enabling the upper vision detection component 62 to accurately reach the designated detection position. Once the target position is reached, the upper vision detection component 62 can perform visual detection on the object at the corresponding position and acquire the required visual information.

[0062] In another embodiment of this utility model, such as Figures 4-5 As shown, the upper vision inspection component 62 includes an upper vision inspection bracket 621 and an upper vision inspection camera 622. The upper vision inspection bracket 621 is fixedly connected to the upper moving Y-axis module 617, and the upper vision inspection camera 622 is fixedly connected to the upper vision inspection bracket 621. The upper vision inspection bracket 621 serves as a connection and support, and it is securely fixed to the upper moving Y-axis module 617. After receiving a control command, the upper moving Y-axis module 617 can move in the Y-axis direction, thereby causing the upper vision inspection bracket 621 to move in the Y-axis direction. At the same time, the upper moving X-axis module 614 can also be controlled to move the connected upper moving Y-axis module 617 and the upper vision inspection bracket 621 in the X-axis direction. Because the upper moving Y-axis module 617 is fixed to the upper moving slide 615 connected to the upper moving X-axis module 614, the movement of the upper moving slide 615 in the X-axis direction is transmitted to the upper vision inspection bracket 621.

[0063] The upper vision inspection camera 622 is fixedly mounted on the upper vision inspection bracket 621. When the upper vision inspection bracket 621 moves in the XY plane along with the upper moving X-axis module 614 and the upper moving Y-axis module 617, the upper vision inspection camera 622 will also move to the corresponding position. Once it reaches the designated inspection position, the upper vision inspection camera 622 will begin to work.

[0064] The upper vision inspection camera 622 passes through the glass cover plate 4 and acquires image information of the top of the PCB on the glass cover plate 4. Using its own image recognition and processing technology, it analyzes and judges the shape, size, position, surface features, etc. of the object, thereby realizing the inspection of the PCB surface.

[0066] Horizontal movement of the glass cover plate 4: The glass fixing base 50 is fixed on the frame 1 as a basic component, providing stable support for the entire mechanism. The glass moving slide rail 51 is fixed on the glass fixing base 50, and the glass moving slider 52 can slide on the glass moving slide rail 51. At the same time, the glass moving guide post 53 is also fixed on the glass fixing base 50, and the glass moving guide block 54 can slide on the glass moving guide post 53. The glass moving frame 55 is fixedly connected to the glass moving guide block 54 and the glass moving slider 52 respectively. When the glass cover needs to move horizontally, the external driving force will act on the glass moving frame 55. Since the glass moving frame 55 is connected to the glass moving slider 52 and the glass moving guide block 54, the glass moving slider 52 will slide on the glass moving slide rail 51, and the glass moving guide block 54 will slide on the glass moving guide post 53. The two work together to ensure that the glass moving frame 55 and other components connected to it can move smoothly in the horizontal direction, realizing the horizontal position adjustment of the glass cover.

[0067] The lifting and moving of the glass cover plate 4: The glass lifting cylinder 56 is fixed on the glass moving frame 55, and the glass lifting slide rail 58 is also fixed on the glass moving frame 55. The glass lifting slider 59 is slidably connected to the glass lifting slide rail 58, and the glass carrier plate 57 is fixedly connected to the glass lifting cylinder 56 and the glass lifting slider 59 respectively. When the glass lifting cylinder 56 is working, the piston rod of the glass lifting cylinder 56 extends or retracts, driving the glass carrier plate 57 to rise or fall. During this process, the glass lifting slider 59 slides on the glass lifting slide rail 58, playing a guiding and stabilizing role, ensuring that the glass carrier plate 57 can rise and fall smoothly. Since the glass cover plate 4 is fixed on the glass carrier plate 57, the glass cover plate 4 will also rise and fall with the glass carrier plate 57, realizing the vertical position adjustment of the glass cover.

[0068] By combining horizontal and vertical movement, the glass cover moving mechanism 5 can accurately move the glass cover plate 4 to a designated position to meet the inspection requirements of different PCB boards.

[0069] In another embodiment of this utility model, such as Figure 7 As shown, the feeding box mechanism 7 includes a feeding box body 71, a feeding tray 72, and a lifting feeding assembly 73. The feeding box body 71 is disposed on one side of the frame 1, the lifting feeding assembly 73 is connected to the feeding box body 71, and the feeding tray 72 is fixedly connected to the lifting feeding assembly 73. The lifting feeding assembly 73 includes a feeding motor 730, a feeding drive wheel 731, a feeding belt 732, a feeding driven wheel 733, a feeding screw 734, a feeding nut 735, a feeding lifting frame 736, a feeding lifting slider 737, and a feeding lifting slide rail 738. The feeding motor 730 is fixedly connected to the frame 1, and the feeding drive wheel 731 is fixedly connected to the frame 1. 31 is fixedly connected to the feeding motor 730. The feeding belt 732 is fixedly wound around the feeding drive wheel 731 and the feeding driven wheel 733 respectively. The feeding driven wheel 733 is fixedly connected to the feeding screw 734. The feeding screw 734 is rotatably connected to the feeding box body 71. The feeding nut 735 is threadedly connected to the feeding screw 734. The feeding lifting frame 736 is fixedly connected to the feeding nut 735 and the feeding lifting slider 737 respectively, and is movably set on the feeding box body 71. The feeding lifting slider 737 is slidably connected to the feeding lifting slide rail 738. The feeding lifting slide rail 738 is fixedly connected to the feeding box body 71.

[0070] The working process of the feeding box mechanism 7 is as follows:

[0071] Power transmission stage:

[0072] The feed motor 730 is fixed to the frame 1. When the feed motor 730 starts, it drives the feed drive wheel 731, which is fixedly connected to it, to rotate. The feed belt 732 is wound around both the feed drive wheel 731 and the feed driven wheel 733. The rotation of the feed drive wheel 731 is transmitted to the feed driven wheel 733 through the feed belt 732, causing the feed driven wheel 733 to rotate as well. This belt drive method can smoothly transmit power and can buffer vibration and impact to a certain extent.

[0073] Lead screw and nut transmission stage:

[0074] The driven feed wheel 733 is fixedly connected to the feed screw 734, so the rotation of the driven feed wheel 733 will drive the feed screw 734 to rotate on the feed box 71. The feed nut 735 and the feed screw 734 are engaged by threads. When the feed screw 734 rotates, the feed nut 735 will move linearly along the feed screw 734 due to the action of the threads. The screw and nut drive has the characteristics of high precision and high load-bearing capacity, and can accurately control the moving distance and speed of the feed nut 735.

[0075] Feed tray 72 lifting stage:

[0076] The feeding lifting frame 736 is fixedly connected to the feeding nut 735 and the feeding lifting slider 737, and is movably disposed within the feeding box 71. The feeding lifting slider 737 is slidably connected to the feeding lifting slide rail 738 fixed on the feeding box 71. When the feeding nut 735 moves linearly along the feeding screw 734, it will drive the feeding lifting frame 736 to move together. The feeding lifting slider 737 slides on the feeding lifting slide rail 738, providing guidance and support for the movement of the feeding lifting frame 736, ensuring its stability and accuracy.

[0077] Since the feeding tray 72 is fixedly connected to the feeding lifting frame 736, the lifting and lowering movement of the feeding lifting frame 736 will drive the feeding tray 72 to rise and fall. By controlling the forward and reverse rotation and the number of revolutions of the feeding motor 730, the feeding tray 72 can be precisely controlled to rise or fall to a specified position to meet different feeding needs, such as lifting the material to a suitable height for subsequent processing or conveying operations.

[0078] In another embodiment of this utility model, such as Figure 8As shown, the discharge box mechanism 9 includes a discharge box body 91, a discharge tray 92, and a lifting discharge assembly 93. The discharge box body 91 is located on one side of the frame 1, the lifting discharge assembly 93 is connected to the discharge box body 91, and the discharge tray 92 is fixedly connected to the lifting discharge assembly 93. The lifting discharge assembly 93 includes a discharge motor 930, a discharge drive wheel 931, a discharge belt 932, a discharge driven wheel 933, a discharge screw 934, a discharge nut 935, a discharge lifting frame 936, a discharge lifting slider 937, and a discharge lifting slide rail 938. The discharge motor 930 is fixedly connected to the frame 1, and the discharge drive wheel 931 is fixedly connected to the frame 1. 31 is fixedly connected to the discharge motor 930. The discharge belt 932 is fixedly wound around the discharge drive wheel 931 and the discharge driven wheel 933 respectively. The discharge driven wheel 933 is fixedly connected to the discharge screw 934. The discharge screw 934 is rotatably connected to the discharge box body 91. The discharge nut 935 is threadedly connected to the discharge screw 934. The discharge lifting frame 936 is fixedly connected to the discharge nut 935 and the discharge lifting slider 937 respectively, and is movably disposed on the discharge box body 91. The discharge lifting slider 937 is slidably connected to the discharge lifting slide rail 938. The discharge lifting slide rail 938 is fixedly connected to the discharge box body 91. The working process of the discharge box mechanism 9 is the same as that of the feeding box mechanism 7.

[0079] In another embodiment of this utility model, such as Figure 9 As shown, the plate-picking mechanism 8 includes a picking base 81, a picking slider 82, a picking base plate 83, a picking rack 84, a picking suction head 85, and a picking X-axis moving module 86. The picking base 81 is fixedly connected to the picking X-axis moving module 86, the picking slider 82 is slidably connected to the picking base 81, the picking base plate 83 is fixedly connected to the picking slider 82, the picking rack 84 is fixedly connected to the picking base plate 83, the picking suction head 85 is fixedly connected to the picking rack 84, and the picking X-axis moving module 86 is fixedly connected to the frame 1.

[0080] The working principle and process of the plate-picking mechanism 8 mainly involve the cooperation between various components to achieve the movement of the picking head 85 in the X-axis direction and the picking and placing of the plate, as detailed below:

[0081] Overall moving base: The material picking X-axis moving module 86 is fixedly connected to the frame 1, providing the entire material picking mechanism 8 with the ability to move in the X-axis direction. When the material picking X-axis moving module 86 receives a control command and starts working, it can drive the material picking base 81 fixedly connected to it to move in the X-axis direction.

[0082] The slider and substrate move in coordination: The picking slider 82 and the picking base 81 are slidably connected, and the picking substrate 83 is fixedly connected to the picking slider 82. When the picking base 81 moves in the X-axis direction with the picking X-axis moving module 86, the picking slider 82 slides on the picking base 81, thereby driving the picking substrate 83 to move together. This slider-base coordination method ensures the stability and smoothness of the picking substrate 83 during movement.

[0083] Connection between the pick-up rack 84 and the pick-up head: The pick-up rack 84 is fixedly connected to the pick-up substrate 83, and the pick-up head 85 is fixedly connected to the pick-up rack 84. Therefore, when the pick-up substrate 83 moves, it will sequentially drive the pick-up rack 84 and the pick-up head 85 to move in the X-axis direction, so that the pick-up head 85 can reach the position where the board needs to be picked up.

[0084] Board picking and placing operation: When the picking head 85 moves above the target board, it generates suction through its internal vacuum system to pick up the PCB board. Then, the picking X-axis moving module 86 operates again, driving the picking base 81, picking slider 82, picking substrate 83, picking rack 84, and picking head 85 to move together, moving the picking head 85 with the board attached to it to the designated placement position. Finally, the picking head 85 stops generating suction, releasing the board, completing the board picking and placing operation.

[0085] In another embodiment of this utility model, multiple material-picking suction heads 85 are provided and are evenly and fixedly connected to the material-picking frame 84. By providing multiple material-picking suction heads 85, the adsorption force can be improved, making it easier to stably adsorb the PCB board.

The lower visual inspection camera 222 and the upper visual inspection camera 622 automatically determine and complete the inspection work through AI, reducing manpower, avoiding the risk of human error and product contact, and improving inspection accuracy and efficiency.

[0087] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
