Description

Technical Field

[0001] The invention relates to the technical field of PC board defect recognition devices, and in particular to an intelligent PC board surface defect recognition device. Background Art

[0002] Polycarbonate (PC) boards include solid boards, hollow boards, corrugated boards and particle boards, and are widely used in many fields such as greenhouses, skylights, carports, awnings, and building curtain walls. However, during the production and use of PC boards, defects often appear on their surfaces, which brings many disadvantages to the performance of PC boards.

[0003] In terms of performance, defects will reduce light transmittance, affecting the growth of plants in greenhouses and the indoor lighting effects of places such as skylights; defects will become stress concentration points, reducing mechanical strength, making PC boards prone to cracking and breaking at the defects when subjected to external forces, shortening their service life. For example, PC boards in outdoor carports and awnings will be damaged because the defects cannot withstand the load; the surface protective layer or structure of the PC board will be damaged, reducing its weather resistance, making it more susceptible to environmental factors and accelerating aging, yellowing, and brittleness;

[0004] In terms of processing and installation, defects on the surface of PC boards will increase the difficulty of processing. When cutting, drilling, bending and other operations, problems such as cracking and edge collapse are likely to occur, which will increase the scrap rate and increase production costs. Defective PC boards cannot fit tightly with the frame or other components during installation, resulting in uneven installation, affecting the installation quality and use effect. For example, when installing a PC board curtain wall, the sealing and stability of the curtain wall will be reduced.

[0005] At present, the machine vision system in the optical inspection equipment can be used to detect the surface defects of PC boards. Its working principle is to collect the surface image of the PC board through a high-definition camera, and use the image processing algorithm to compare the color, brightness, texture and other characteristics of the normal and suspected defective areas to judge the defects; but in actual inspection, if the special type of PC board such as the corrugated board is placed at an angle, the PC board is not parallel to the inspection equipment, and the high-definition camera can only shoot the surface position, which will cause the inclined PC board to be partially blocked by the wave part, and then it will cause the local irradiation to be unable to cause many problems. For the test results, it will reduce the accuracy of the detection, increase the risk of misjudgment and missed judgment, and cause incomplete data, affecting the reliability of quality assessment and analysis. For subsequent use, if the PC board without defects is misjudged as qualified and put into use, it will bring quality risks, such as affecting the light transmission and insulation of the greenhouse, the sealing stability of the building curtain wall, etc.; it will also increase the maintenance cost and frequently replace the board; there are even safety risks. In places with high safety requirements, it will also cause dangerous situations such as rupture and falling off due to undetected serious defects, threatening the safety of personnel and property.

[0006] Therefore, we proposed a PC board surface intelligent defect recognition device to solve the above problems. Summary of the invention

[0022] 1. The present application can effectively ensure that the wave PC board is in a parallel state with the defect recognition visual device before defect recognition through the design of a stable recognition auxiliary component, thereby avoiding the situation in actual detection where the placement of the wave PC board is not parallel to the defect recognition visual device, resulting in insufficient local illumination of the wave PC board to be tested, affecting the accuracy of defect detection, improving detection accuracy, reducing the risk of misjudgment and missed judgment, effectively ensuring the integrity of image data, and improving the reliability of wave PC board quality assessment and analysis.

[0041] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0042] Example

[0043] Please refer to Figures 1 to 5 , Figure 8 , Fig. 9 As shown:

[0044] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a PC board surface intelligent defect recognition device, including: a base plate seat 1, a cover plate 2, an auxiliary cavity 3, a defect recognition visual device 4, and a wavy PC board 5, the cover plate 2 is fixedly connected to the base plate seat 1, the auxiliary cavity 3 and the defect recognition visual device 4 are both fixedly connected to the cover plate 2, and the wavy PC board 5 is located on the conveyor belt on the base plate seat 1, and also includes: a multi-application drive component 6, a stable recognition auxiliary component 7, and an effective recognition processing component 8, and the stable recognition auxiliary component 7 is located on one side of the multi-application drive component 6 and the effective recognition processing component 8;

[0045] The multi-application drive assembly 6 is used for the operation of the equipment;

[0046] The stable identification auxiliary component 7 is used to detect the surface height of the wave PC board 5 to determine whether the wave PC board 5 meets the process requirements for defect detection;

[0047] The multi-application drive assembly 6 includes a half gear A601 fixedly connected to the auxiliary cavity 3 through an auxiliary rod, a driving member 602 is arranged on one side of the half gear A601, a plug-in column 603 is horizontally plugged into the auxiliary cavity 3, and a half gear B604 and a half gear C605 are fixedly connected to the plug-in column 603;

[0048] The stable identification auxiliary component 7 includes a long cavity A701 fixedly connected to the outer end of the plug-in column 603, a guide groove 702 is provided on the long cavity A701, a sliding plate 703 is slidably connected in the long cavity A701, through holes 704 are equidistantly provided on the sliding plate 703, a connecting rod 705 is fixedly connected to the bottom surface of the sliding plate 703, a detection rod 706 is fixedly connected to the bottom end of the connecting rod 705, a guide rod 707 is slidably connected in the guide groove 702, and the bottom end of the guide rod 707 is fixedly connected to the detection rod 706.

[0049] A magnet 708 is fixedly connected to the upper end surface of the sliding plate 703, and a Hall switch A709 and a Hall switch B710 are fixedly connected to the outer wall of the long cavity A701 at different heights, and the Hall switch A709 is arranged below the Hall switch B710.

[0050] in:

[0051] The shape of the inner surface of the base plate 1 is set to be concave.

[0052] In actual testing, if a special type of PC board such as a wavy PC board 5 is not placed parallel to the testing device, i.e., the defect recognition visual device 4, it will result in partial inability to be illuminated, which will reduce the accuracy of the test results.

[0053] The multi-application drive assembly 6 is mainly used for the operation of the equipment.

[0054] The wheel diameter of the half gear A601 is larger than the wheel diameters of the half gear B604 and the half gear C605.

[0055] The driving member 602 is composed of a support frame and an electric driving wheel, and the friction coefficient between the driving wheel and the side wall of the half gear A601 is relatively large.

[0056] The wheel diameters of the half gear B604 and the half gear C605 are the same.

[0057] The stable identification auxiliary component 7 is mainly used to detect the surface height of the corrugated PC board 5 and determine whether the corrugated PC board 5 meets the process requirements of defect detection.

[0058] The inner cavity of the long cavity A701 is provided with water, and the plug-in column 603 that drives the long cavity A701 to rotate rotates slowly. When the long cavity A701 is swung downward, the water on the upper surface of the sliding plate 703 will first run to the bottom of the sliding plate 703 through the through hole 704. At this time, the sliding plate 703 has the aqueous solution as a buffer when the detection rod 706 moves downward, that is, the water is mainly used to cooperate with the movement stability of the sliding plate 703 in the long cavity A701, reduce the vibration of equipment components caused by the movement of the sliding plate 703 in the long cavity A701, and improve the overall service life of the equipment.

[0059] The guide rod 707 is slidably adapted to the guide groove 702 .

[0060] There are two groups of stable identification auxiliary components 7, which are respectively arranged on both sides of the wavy PC board 5; one group is composed of two Hall switches A709, Hall switch B710 and two magnets 708. When the two magnets 708 in the same group move to the same height, that is, the two magnets 708 act on the two Hall switches A709 / Hall switches B710, it means that the height of the wavy PC board 5 on this side is consistent; if the magnets 708 in the same group move to different heights, one is the same height as the Hall switch A709 and the other is the same height as the Hall switch B710, it means that the height of the wavy PC board 5 on this side is inconsistent; further, through the combination of the two groups, it can be known whether the two sides of this wavy PC board 5 are at the same height, that is, whether they are parallel to the detection equipment, that is, parallel to the defect recognition visual device 4 at this time.

[0061] It should be noted that the connection between equidistance and parallelism is: if the distance from a straight line and each point on it to the straight line is equal, that is to say, the height / distance between them is the same.

[0062] First, the auxiliary cavity 3 is parallel to the defect recognition visual device 4 when installed and fixed. Then, if the two sets of detection rods 706 move the magnets 708 on the sliding plate 703 to the same height, it means that the distance from the surface of the wave PC board 5 in contact with the multiple detection rods 706 to the auxiliary cavity 3 is the same. At this time, it can be explained that the wave PC board 5 is not tilted, or the conveyor belt on the base plate seat 1 is in a normal horizontal conveying state and has not been deformed.

[0063] For further examples, please refer to Figure 3 , Figures 5 to 9 As shown:

[0064] The effective identification processing component 8 is used to remove dust on the defect identification visual device 4 and the wave PC board 5 and manufacturing debris of the wave PC board 5, so as to ensure the accuracy of the defect identification visual device 4 in identifying the defect of the wave PC board 5;

[0065] The effective identification processing component 8 includes an 8-shaped groove 801 opened on the rear end face of the half gear A601, a sliding rod 802 is slidably connected in the 8-shaped groove 801, and an air push rod 803 is rotatably connected to the sliding rod 802. The inner cavity of the auxiliary cavity 3 is fixedly connected to a fixing frame 804, and a long cavity B805 is equidistantly fixedly connected to the fixing frame 804. The upper end of the long cavity B805 is fixedly connected to a trumpet-shaped air expander 806. Two long cavities B805 are provided, and the bottom end of the other long cavity B805 is fixedly connected to a perforated column cavity 807.

[0066] in:

[0067] The effective identification processing component 8 is mainly used to remove dust on the defect identification visual device 4 and the wavy PC board 5 as well as manufacturing debris of the wavy PC board 5, so as to ensure the accuracy of the defect identification visual device 4 in identifying defects of the wavy PC board 5.

[0068] The sliding rod 802 is slidably adapted to the half gear A601.

[0069] The air push rod 803 is composed of a column rod and an air push sheet.

[0070] The sliding rod 802, the air push rod 803, and the long cavity B805 form a group. There are two groups in total, one group serves the trumpet-shaped air expander 806, and the other group serves the holed column cavity 807. Since the working process is the same, only one group is described.

[0071] The effective identification processing component 8 opens an 8-shaped groove 801 based on the half gear A601, and can provide precision maintenance assistance for the auxiliary intelligent defect recognition device in the future. Specifically, it cleans up interference sources such as debris that interfere with recognition. In addition, the stable identification auxiliary component 7 and the effective identification processing component 8 are driven by the multi-application drive component 6 to work. One drive can realize the activation of multiple functions, and the component structure is compactly designed. The structures are interconnected, which effectively reduces equipment components and reduces maintenance costs.

[0072] Everything in the above example works like this:

[0073] It should be noted that:

[0074] This solution is based on the recognition device and carries out auxiliary design to ensure the accuracy of recognition; that is, the position of the existing defect recognition visual device 4 cannot be adjusted during shooting and recognition, but if the wavy PC board 5 is in an inclined state during transportation, the accuracy of the defect recognition visual device 4 shooting and recognition will be greatly reduced. That is, the defect recognition device is improved in this application and becomes an electronic shooting and recognition plus physical / mechanical judgment method, so as to improve the recognition reliability and achieve accurate recognition effect.

[0075] The following is the working process of the multi-application drive component 6 and the stable identification auxiliary component 7:

[0076] When in use, the driving member 602 is started, and the driving wheel in the driving member 602 causes the half gear A601 to rotate. Figure 3 During the counterclockwise rotation of the half gear A601, the half gear A601 will first mesh with the half gear C605, and under the action of the teeth, the half gear C605 will rotate counterclockwise with the fixed plug-in column 603, at which time the plug-in column 603 will lift the long cavity A701 upward; further, as the half gear A601 continues to rotate, the half gear A601 will no longer mesh with the half gear C605, but will mesh with the half gear B604 during the rotation, and during the meshing, the half gear B604 will press the long cavity A701 downward, and further, as the half gear A601 continues to rotate, the long cavity A701 will repeatedly lift up and then swing down;

[0077] Furthermore, when the long cavity A701 swings downward, the sliding plate 703 slidably connected in the long cavity A701 will slide downward in the long cavity A701 under the action of the gravity of the detection rod 706 on the connecting rod 705, and the detection rod 706 at this time will fall on the wave PC board 5 being transported by the base plate seat 1. Furthermore, since it is known that the stable identification auxiliary component 7 is provided with two groups, which are respectively arranged on both sides of the wave PC board 5; one group is composed of two Hall switches A709, Hall switch B710 and two magnets 708. When the two magnets 708 of the same group move to the same height, that is, the two magnets 708 act on the two Hall switches A709 or Hall switch B710 synchronously, it means that The height of the wave PC board 5 on this side is consistent; if the magnets 708 of the same group move to different heights, one is at the same height as the Hall switch A709, and the other is at the same height as the Hall switch B710, it means that the height of the wave PC board 5 on this side is inconsistent; further, through the integration of the two groups, it can be known whether the two sides of this wave PC board 5 are at the same height, that is, whether it is parallel to the detection device, that is, parallel to the defect recognition visual device 4 at this time. Therefore, when the wave PC board 5 is not parallel to the defect recognition visual device 4 due to its placement position, the stable recognition auxiliary component 7 will send a signal to the device through the feedback of the Hall switch group that the wave PC board 5 needs to be adjusted at this time, so as to ensure the complete collection of the surface image information of the wave PC board 5 and improve the accuracy of defect recognition;

[0078] Furthermore, the present application can provide effective assistance for defect identification of the corrugated PC board 5 by setting the inner surface shape of the base plate seat 1 to be concave, and can effectively ensure the stable transportation of the corrugated PC board 5 on the base plate seat 1; that is, in the actual transportation process, this design can effectively avoid the position deviation of the corrugated PC board 5 due to transportation problems, and avoid the indirect influence of the position deviation of the corrugated PC board 5 due to transportation on the accuracy of detection, laying a solid foundation for ensuring the accuracy of detection, and making the entire detection process more reliable and efficient.

[0079] Furthermore, the present application arranges an aqueous solution in the inner cavity of the long cavity A701. When the sliding plate 703 moves in the inner cavity of the long cavity A701, the aqueous solution can flow through the through hole 704 opened on the sliding plate 703, so as to avoid the vibration caused by the rapid movement of the sliding plate 703 in the long cavity A701, thereby improving the movement stability of the sliding plate 703 in the long cavity A701, and can effectively reduce the vibration of equipment components caused by the movement of the sliding plate 703 in the long cavity A701, avoid damage to the equipment or loosening of parts caused by vibration, and effectively improve the overall service life of the equipment.

[0080] Please refer to the above working process Figures 1 to 5 , Figure 8 , Fig. 9 .

[0081] Furthermore, the present application can effectively ensure that the wavy PC board 5 is in a parallel state with the defect recognition visual device 4 before defect recognition through the design of the stable identification auxiliary component 7, so as to avoid the situation in actual detection where the placement position of the wavy PC board 5 is not parallel to the defect recognition visual device 4, resulting in insufficient local illumination of the wavy PC board 5 to be tested, which affects the accuracy of defect detection, improves the detection accuracy, reduces the risk of misjudgment and missed judgment, effectively ensures the integrity of the image data, and improves the reliability of quality assessment and analysis of the wavy PC board 5.

[0082] The following is the working process of the effective identification processing component 8:

[0083] Furthermore, when the half gear A601 rotates, the sliding rod 802 sliding in the 8-shaped groove 801 opened on the half gear A601 will carry the push rod 803 fixedly connected thereto to move in the long cavity B805 fixed on the fixing frame 804. Furthermore, when the push rod 803 moves in the long cavity B805, the gas in the long cavity B805 will be pushed out, and the discharge area of ​​the air flow will be increased through the trumpet-shaped air expander 806, so as to remove the air flow. Clean the dust and debris on the lens of the defect recognition visual device 4; further, since the sliding rod 802, the air push rod 803, and the long cavity B805 are a group, there are two groups in total, one group serves the trumpet-shaped air expansion member 806, and the other group serves the perforated column cavity member 807. Therefore, when the airflow released from the trumpet-shaped air expansion member 806 cleans the defect recognition visual device 4, there will also be airflow through the perforated column cavity member 807 to the wave PC board 5 transported on the bottom plate seat 1 for cleaning;

[0084] Furthermore, the present application can effectively remove debris on the wave PC board 5 and clean the lens of the defect recognition visual device 4 during the defect detection of the wave PC board 5 through the design of the effective identification processing component 8. This operation has many benefits. On the one hand, it can reduce interference sources, avoid scattering and blocking of light by debris, and avoid image blurring and distortion caused by impurities on the lens of the defect recognition visual device 4. It can effectively highlight the defect characteristics on the wave PC board 5, improve detection accuracy, and reduce repeated detection due to misjudgment. On the other hand, it can protect the defect recognition visual device 4, avoid lens wear due to dust and stains and collision and scratching by debris, extend its service life, reduce equipment maintenance costs, ensure the stability of the detection system, improve the consistency of detection results, reduce the number of equipment adjustments and calibrations, and provide strong guarantees for high-quality defect detection. That is, when detecting defects on the wave PC board 5, removing debris on the wave PC board 5 and cleaning the lens of the defect recognition visual device 4 can reduce interference sources, highlight defect characteristics, improve detection efficiency, enhance equipment stability and life, and provide strong guarantees for high-quality defect detection.
