Description

Technical Field

[0001] This invention relates to the field of PCB board visual re-judgment technology, and in particular to a visual re-judgment machine. Background Technology

[0002] With the rapid development of surface mount technology, the integration and component density of PCBs are constantly increasing, placing higher demands on quality inspection during the PCB manufacturing process. Automated Optical Inspection (AOI) equipment has been widely used in the online inspection stage of PCB production lines, capable of quickly identifying NG boards that may have defects such as poor soldering, component misalignment, or missing components. However, AOI equipment is limited by its imaging principles and algorithm threshold settings, resulting in a certain percentage of false positives and false negatives. Therefore, in actual production, NG boards detected by AOI usually require manual secondary inspection for confirmation.

[0003] Currently, traditional re-inspection methods mainly rely on operators using magnifying glasses or simple microscopes to observe suspicious components on NG boards one by one. This manual re-inspection method has many shortcomings: First, operators are prone to visual fatigue from prolonged close-range observation of components, leading to a significant increase in missed and false positive rates. Moreover, manual re-inspection is inefficient and cannot match the production rhythm of automated production lines, becoming a bottleneck for production line efficiency. Second, the micro-components on PCB boards are extremely small, and traditional magnifying glasses cannot provide sufficiently clear images. Furthermore, they cannot observe the sides and bottom solder joints of components from multiple angles, easily overlooking critical defects. Third, if NG boards need to be removed from the production line for separate processing during the re-inspection process, it will affect the normal flow of OK boards and reduce the overall production line efficiency. Fourth, different PCB boards have board warping and component height differences, and traditional fixed-focus optical systems cannot maintain clear imaging across the entire board, affecting the accuracy of re-inspection. Therefore, we propose a visual re-inspection machine. Summary of the Invention

[0004] In order to overcome the technical problems existing in the prior art, the present invention provides a visual re-judgment machine.

[0005] To solve the above technical problems, the present invention provides the following technical solution: including a cabinet, a detection component and a conveying component are arranged on the upper side of the cabinet, the detection component covers the upper side of the conveying component, an auxiliary component is arranged on the side of the conveying component, and a material plate is arranged on the upper side of the conveying component; The detection component includes a three-axis transfer device, which is fixedly installed on the upper side of the cabinet. A rotating visual inspection component is provided on the side of the three-axis transfer device, which performs 360-degree visual inspection of the material board.

The first conveyor line is slidably disposed on the upper side of the cabinet, and the second conveyor line is fixedly disposed on the upper side of the cabinet. Lifting components are provided on the sides of the first and second conveyor lines. The lifting components lift the unqualified material plate to make it detach from the sides of the first and second conveyor lines. A rotating visual inspection component performs a visual re-inspection of the unqualified material plate. The auxiliary component includes a driving component, which includes an electric slide table and an electric push rod. A conveying component is provided on the side of the electric push rod.

After the material plate is lifted, the conveying component can convey it. The conveying component is provided with a support component, which can support the material plate to produce an inclined state, and cooperate with the rotating visual inspection component for visual re-inspection.

[0006] Furthermore, the rotating inspection component includes a mounting bracket fixedly installed on the side of the triaxial transfer device.

An adjustment frame is slidably installed on the side of the turntable. A vision camera is fixedly installed on the side of the adjustment frame. The vision camera is tilted at a 45-degree angle on the side of the adjustment frame.

[0007] Furthermore, the first and second conveyor lines are mirror images of each other. An adjustment module is provided between the sides of the first and second conveyor lines. The adjustment module consists of a motor, two sets of threaded rods, and a synchronous belt. The motor is fixed to the side of the second conveyor line, and the threaded rods are fixed to the output end of the motor. The first conveyor line is threaded onto the side of the threaded rods. The motor drives the threaded rods to rotate, and the synchronous belt cooperates with the two sets of threaded rods to rotate synchronously, so that the first conveyor line is driven to slide on the upper side of the cabinet to adjust the distance between the first and second conveyor lines. Limiters are fixedly installed on the sides of the first and second conveyor lines that are close to each other.

[0008] Furthermore, the lifting component includes a lifting module fixedly installed on the lower side of the cabinet, and the lifting module extends through the cabinet to the lower side of the first conveyor line and the second conveyor line. A lifting frame is mirror-installed on the upper side of the lifting module, and the lifting frame is slidably installed on the side of the first conveyor line and the second conveyor line that are far apart from each other. The lifting frame corresponding to the first conveyor line is slidably installed on the side of the lifting module, and the lifting frame corresponding to the second conveyor line is fixedly installed on the side of the lifting module.

[0009] Furthermore, the lifting component also includes slots formed on the upper side of the first and second conveyor lines, and support blocks are fixedly installed at equal intervals on the side of the lifting frame corresponding to the slot positions.

[0010] Furthermore, the driving component includes an electric slide table equidistantly arranged on the side of the lifting frame, a fixing frame fixedly arranged between the electric slide table and the side of the lifting frame, a mating groove opened on the side of the lifting frame corresponding to the position of the electric slide table, a power supply module fixedly installed on the side of the slider of the electric slide table and the power supply module corresponding to the position of the mating groove, and an electric push rod fixedly arranged on the side of the power supply module with the output end of the electric push rod facing the mating groove.

[0011] Furthermore, the conveying component is fixedly installed on the micro motor at the output end of the electric push rod. The micro motor is a DC motor that can rotate freely when not powered. A roller is fixedly installed at the output end of the micro motor, and the roller corresponds to the position inside the mating groove.

[0012] Furthermore, the support component includes a connecting frame fixedly installed on the side of the micro motor and the connecting frame covering the roller. A shaft is rotatably installed through the side of the connecting frame. A torsion spring is fixedly connected between the side of the shaft and the inner side of the connecting frame and the torsion spring is movably sleeved on the side of the shaft. A mating block is fixedly installed on the side of the shaft away from the roller.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention achieves automatic lifting and re-judgment of NG boards by setting up a conveying assembly consisting of a first conveyor line and a second conveyor line, in conjunction with a lifting module-driven lifting frame and support block. When the detection assembly determines that the material board is unqualified, the lifting module drives the lifting frame to rise, and the support block extends from the slot to lift the NG board. At this time, the OK board can still flow forward normally through the first and second conveyor lines, realizing the parallel operation of NG re-judgment and OK transmission, solving the drawback of the traditional solution that requires production to stop or divert for re-judgment. On this basis, through the coordinated cooperation of a three-axis transfer device, displacement sensor, rotary motor and auxiliary components, the entire re-judgment process of NG board from lifting, dynamic focusing, multi-angle visual re-judgment to friction-driven discharge is fully automated without manual intervention. While ensuring that the production line rhythm is not interrupted, it greatly reduces the labor intensity of operators, avoids the visual fatigue and subjective misjudgment problems that are easy to cause by manual re-judgment, and improves the automation level of the production line.

[0014] 2. This invention integrates a triaxial transfer device and a displacement sensor into the detection component. The displacement sensor is used to detect the height data of the material board and its surface components in real time. The triaxial transfer device drives the mounting frame and vision camera to perform dynamic Z-axis focusing compensation based on the detection data. This overcomes the imaging blurring problem caused by PCB board warping and component height differences, and ensures that the vision camera always maintains the best focal plane within the entire board scanning range, obtaining high-precision and high-definition re-judgment images.

[0015] 3. This invention uses a rotating motor to drive a turntable frame to rotate a vision camera 360 degrees. Combined with the structure in which the vision camera is installed at a 45-degree angle on the adjustment frame, the vision camera can observe suspicious components on the NG board from any spatial angle. It is especially suitable for component types such as BGA and QFN, where the bottom pins are not visible or the side wall defects are difficult to detect, effectively eliminating the detection blind zone under a single vertical view.

[0016] 4. By setting up an electric slide, electric push rod and mating block in the auxiliary components, the present invention can drive one side of the material board to rise and the other side to fall during the re-judgment process, so that the material board as a whole presents an inclined posture. With the elastic adaptive structure of the shaft and torsion spring, the mating block is always in contact with the lower side of the material board to achieve stable support. This further compensates for the observation angle of the vision camera, enabling the vision camera to capture key defect features such as component sidewalls and solder joint tin climbing status from the inclined incident direction, thus broadening the detection coverage of the re-judgment system.

[0017] 5. This invention utilizes the linkage structure of the electric slide, electric push rod, micro motor, and roller in the auxiliary components. During normal testing, the roller is in contact with the upper side of the material plate for rolling and limiting, effectively suppressing plate warping and ensuring the material plate is flat during testing. When the re-judgment is completed and material needs to be discharged, the micro motor drives the roller to rotate, and the friction between the roller and the material plate drives the NG plate out from the upper side of the support block in the lifting state. There is no need to set up an additional push rod or robotic arm material handling mechanism. The structure is simple and compact, and the operation is reliable and efficient.

[0018] 6. This invention uses an adjustment module to drive the first conveyor line to slide and adjust the distance relative to the second conveyor line, enabling the conveying components to quickly adapt to PCB boards of different widths without replacing any parts, thus improving the equipment's versatility and line change efficiency.

Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0022] Example: Figure 1 As shown, the visual inspection machine includes a cabinet 1, which integrates control and power supply components. A detection component 2 and a conveying component 3 are located on the upper side of the cabinet 1, with the detection component 2 covering the upper side of the conveying component 3. An auxiliary component 4 is located on the side of the conveying component 3, and a material board 5 (a PCB board) is located on the upper side of the conveying component 3. Specifically, the conveying component 3 transports the material board 5 normally, the detection component 2 performs multi-directional visual inspection of the material board 5, the conveying component 3 can lift and re-inspect unqualified material boards 5, the auxiliary component 4 can constrain the material board 5 and adjust its overall angle to facilitate visual inspection, and the auxiliary component 4 can discharge unqualified material boards 5.

[0023] like Figures 2 to 4As shown, the detection component 2 includes a three-axis transfer device 21, which is fixedly installed on the upper side of the cabinet 1. A mounting frame 22, which is rectangular, is fixedly installed on the side of the three-axis transfer device 21 and moves in three directions under the drive of the three-axis transfer device 21. A rotary motor 23 is fixedly installed on the side of the mounting frame 22, and a turntable frame 24, which is U-shaped, is fixedly installed at the output end of the rotary motor 23. A lighting lamp 25 is mirrored on the lower side of the turntable frame 24, and a displacement sensor 26 is vertically fixed at the center of the lower side of the turntable frame 24. An adjustment frame 27 is slidably installed on the side of the turntable frame 24 and is secured by screws. A vision camera 28 is fixedly mounted on the side of the adjustment frame 27, and the vision camera 28 is set at a 45-degree angle to the side of the adjustment frame 27. Specifically, the components on the side of the mounting frame 22 are driven to move in three directions by the three-axis transfer device 21, and the turntable frame 24 can be rotated 360 degrees by the rotary motor 23. The lighting lamp 25 provides supplementary lighting. In this way, the vision camera 28 can perform full-coverage visual inspection of the material plate 5. The displacement sensor 26 simultaneously detects the height of the components on the side of the material plate 5. The three-axis transfer device 21 adjusts the height of the mounting frame 22 according to the detection data of the displacement sensor 26 to ensure that the visual imaging of the vision camera 28 achieves high precision and high definition.

[0024] like Figures 5 to 8 As shown, the conveying assembly 3 includes a first conveyor line 31 and a second conveyor line 32. The first and second conveyor lines 31 and 32 are belt conveyors, arranged mirror images of each other. The first conveyor line 31 is slidably positioned on the upper side of the cabinet 1, and the second conveyor line 32 is fixedly positioned on the upper side of the cabinet 1. An adjustment module 33 is provided between the sides of the first and second conveyor lines 31 and 32. The adjustment module 33 consists of a motor, two sets of threaded rods, and a synchronous belt. The motor is fixed to the side of the second conveyor line 32, and the threaded rods are fixed to the motor output end. The first conveyor line 31 is threaded onto the side of the threaded rods. The motor drives the threaded rods to rotate, and the belt moves through the belt. The step belt, in conjunction with two sets of threaded rods, rotates synchronously, causing the first conveyor line 31 to slide on the upper side of the cabinet 1. The distance between the first conveyor line 31 and the second conveyor line 32 is adjusted, and a limiter 34 is fixedly installed on the side of the first conveyor line 31 and the second conveyor line 32 that are close to each other. Specifically, the first conveyor line 31 is moved and adjusted by the adjustment module 33, so that the first conveyor line 31 and the second conveyor line 32 can be adapted to convey material plates 5 of different sizes. When the material plate 5 is placed on the upper side of the first conveyor line 31 and the second conveyor line 32, the first conveyor line 31 and the second conveyor line 32 can convey the material plate 5, and the limiter 34 extends to limit the material plate 5. A lifting module 35 is fixedly installed on the lower side of the cabinet 1, extending through the cabinet 1 to the lower side of the first conveyor line 31 and the second conveyor line 32. A lifting frame 36 is mirror-imagely arranged on the upper side of the lifting module 35, and the lifting frames 36 are slidably installed on the sides of the first conveyor line 31 and the second conveyor line 32 that are far apart from each other. The lifting frame 36 corresponding to the first conveyor line 31 is slidably arranged on the side of the lifting module 35, and the lifting frame 36 corresponding to the second conveyor line 32 is fixedly arranged on the side of the lifting module 35. A slot 37 is formed on the upper side of the first conveyor line 31 and the second conveyor line 32. The slot 37 is a rectangular slot. The conveyor belts on the sides of the first conveyor line 31 and the second conveyor line 32 are supported by supporting wheels to avoid the position of the slot 37. Support blocks 38 are fixedly installed at equal intervals on the side of the lifting frame 36 corresponding to the position of the slot 37. 38 is an "L"-shaped block; specifically, the material plate 5 is conveyed to the limiter 34 by the first conveyor line 31 and the second conveyor line 32 and is restricted. At this time, the support block 38 is inside the slot 37, and the material plate 5 is above the support block 38. At this time, the vision camera 28 performs visual inspection on the material plate 5. When the material plate 5 is normal and qualified, the first conveyor line 31 and the second conveyor line 32 can continue to convey it to the subsequent qualified process. If the material plate 5 fails the inspection, the lifting module 35 lifts it up by the lifting frame 36, and the support block 38 can move out of the slot 37 to support the material plate 5 to move upward. At this time, the vision camera 28 performs a re-inspection on the material plate 5. The auxiliary component 4 can constrain the tilt of the material plate 5 for auxiliary inspection, and can also convey the unqualified material plate 5 to the subsequent process.

[0025] like Figures 6 to 10As shown, the auxiliary component 4 includes an electric slide table 41, which is equidistantly positioned on the side of the lifting frame 36. A fixing frame 411 is fixedly installed between the electric slide table 41 and the side of the lifting frame 36, vertically positioning the electric slide table 41 on the side of the lifting frame 36 via the fixing frame 411. A mating groove 42 is provided on the side of the lifting frame 36 corresponding to the position of the electric slide table 41. The mating groove 42 is a rectangular groove. A power supply module 43 is fixedly installed on the side of the slider of the electric slide table 41, with the power supply module 43 corresponding to the position of the mating groove 42. The power supply module 43 is a rechargeable and dischargeable battery module. An electric push rod 44 is fixedly installed on the side of the power supply module 43, with the output end of the electric push rod 44 facing the mating groove 42. The groove 42 is configured such that the electric actuator 44 and the power supply module 43 are connected by wires. A micro motor 45 is fixedly installed at the output end of the electric actuator 44 and is also connected to the power supply module 43 by wires. The micro motor 45 is a DC motor and is selected to be a model that can rotate freely when not powered. A roller 46 is fixedly installed at the output end of the micro motor 45, and the roller 46 corresponds to the position inside the groove 42. A connecting frame 47 is fixedly installed on the side of the micro motor 45 and covers the roller 46. The connecting frame 47 is a "C"-shaped frame. A shaft 48 is rotatably installed through the side of the connecting frame 47. The shaft 48 has a "T"-shaped cross-section. A cylindrical rod is fixedly connected to a torsion spring 481 between the side of the shaft 48 and the inner side of the connecting frame 47, and the torsion spring 481 is movably sleeved on the side of the shaft 48. A mating block 49 is fixedly installed on the side of the shaft 48 away from the roller 46. The mating block 49 is a rectangular block with a rubber layer on the side. Specifically, the electric slide table 41 drives the power supply module 43 to lift and lower as a whole, and cooperates with the electric push rod 44 to drive the micro motor 45 to push and pull, thereby realizing the bidirectional movement of the micro motor 45 and its side components. When the material plate 5 is normally conveyed to the limiter 34 position by the first conveyor line 31 and the second conveyor line 32, the electric slide table 41 and the electric push rod 44 cooperate to move the roller 46 to the upper side of the material plate 5. The position can constrain the material plate 5 to keep it flat. With the help of vision camera 28, vision inspection is performed. When the material plate 5 is qualified, micro motor 45 directly drives roller 46 to rotate. With the help of the first conveyor line 31 and the second conveyor line 32, the material plate 5 is transported to the qualified subsequent process. When the material plate 5 fails the inspection, the support block 38 lifts the material plate 5. The electric slide table 41 moves up with the roller 46. At this time, the vision camera 28 performs a re-inspection. After the re-inspection, the micro motor 45 drives the roller 46 to rotate. At this time, the roller 46 drives the material plate 5 out from the upper side of the support block 38. Then, the external robotic arm clamps the material plate 5 to the corresponding process.When the vision camera 28 re-inspects the material plate 5, the micro motor 45 is energized by the sliding table 41 and the electric push rod 44, causing the mating block 49 to insert into the lower position of the material plate 5. The mating block 49 supports the material plate 5, causing the sliding table 41 on one side of the material plate 5 to rise and the sliding table 41 on the other side of the material plate 5 to fall. At this time, the mating block 49 supports the material plate 5 in an inclined position. The mating block 49, supported on the lower side of the material plate 5, is constrained by the shaft 48, resulting in a rotational engagement with the inclined state of the material plate 5. When the mating block 49 does not support the material plate 5, the shaft 48 is elastically reset by the torsion spring 481, keeping the mating block 49 in a horizontal state.

[0026] Working principle: In use: First, normal testing is performed. The motor driving the threaded rod of the adjustment module 33 rotates, causing the first conveyor line 31 to engage with the threaded rod, thus sliding on the upper side of the cabinet 1. The lifting frame 36 on the side of the first conveyor line 31 slides on the side of the lifting module 35, thereby adjusting the distance between the second conveyor line 32 and the first conveyor line 31. The material plate 5 is placed on the first conveyor line 31 and the second conveyor line 32, and is conveyed by the first conveyor line 31 and the second conveyor line 32 to the extension position of the limiter 34, where it is limited. At this time, the electric slide table 41 and the electric push rod 44 cooperate to drive the micro motor 45 to move bidirectionally, so that the roller 46 is in contact with the upper side of the material plate 5. At this time, the micro motor 45 is not powered and the roller 46 can rotate freely. The roller 46 is in contact with the upper side of the material plate 5 for rolling limit, so that the material plate 5 is kept flat. At this time, the three-axis transfer device 21 drives the mounting frame 22 and its side components to move in three directions. The vision camera 28 performs visual inspection on the material plate 5. The synchronous rotary motor 23 drives the turntable frame 24 to rotate, so that the vision camera 28 can rotate 360 ​​degrees to inspect and cover the entire area of ​​the material plate 5. After the inspection is qualified, the limiter 34 retracts and releases the limit. The first conveyor line 31 and the second conveyor line 32 continue to transport the material plate 5 to the discharge port. The external robotic arm clamps the material plate 5 to the corresponding process. The second step is a re-inspection. If material plate 5 fails the normal inspection, the lifting module 35 pushes the lifting frame 36 upwards. The support block 38 on the side of the lifting frame 36 slides out from the slot 37 to support the material plate 5 during the lifting operation. The electric slide table 41 and electric push rod 44 keep the roller 46 on the upper side of the material plate 5 to ensure the stability of the material plate 5 during lifting. Subsequently, the three-axis transfer device 21 drives the adjusting frame 27 to perform a visual re-inspection of the material plate 5. During the re-inspection, the electric slide table 41 and electric push rod 44 work together to drive the material plate 5... The mating block 49 is supported on the lower side of the material plate 5. The electric slide 41 on one side of the material plate 5 rises and the electric slide 41 on the other side falls, causing the mating block 49 to tilt the material plate 5. At this time, the mating block 49 is constrained by the shaft 48 and rotates, so that the mating block 49 always fits against the lower side of the material plate 5 for effective support. The torsion spring 481 produces an elastic reset effect on the shaft 48. In this way, by compensating for the tilt of the material plate 5, the vision camera 28 can perform visual inspection of the material plate 5 without blind spots. The third step is to re-inspect the material. After the visual re-inspection is completed, the electric slide table 41 and the electric push rod 44 drive the roller 46 to fit against the upper side of the material plate 5. The micro motor 45 drives the roller 46 to rotate. The roller 46 makes frictional contact with the upper side of the material plate 5, and the material plate 5 can slide out on the upper side of the support block 38. The material plate 5 is then clamped to the corresponding process by the external robotic arm. At this time, when the unqualified material plate 5 is re-inspected, the subsequent material plate 5 is simultaneously conveyed to the position of the limiter 34 through the first conveyor line 31 and the second conveyor line 32.
