[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose. Example
[0021] refer to Figures 1-2 This embodiment proposes a sheet metal edge banding inspection device for inspecting sheet metal after edge banding or for detecting edge defects. The sheet metal edge banding inspection device includes:
[0022] Conveyor belt 1 is used to transport the sheet material. Conveyor belt 1 needs to ensure smooth transport to reduce vertical vibration of the sheet material during transport, thereby ensuring inspection accuracy. Generally, conveyor belt 1 is horizontally positioned, which not only facilitates sheet material inspection but also allows for better control of the transport. However, slight inclination at some angles cannot be ruled out, which will not be elaborated here. To further improve inspection accuracy, conveyor belt 1 can include multiple transport units. These units are sequentially connected end-to-end on the same plane in the transport direction, forming a segmented transport. This segmented arrangement shortens the transport length of each unit, increasing transport smoothness. Each transport unit can be mounted on a bracket, which forms a supporting foundation, ensuring the installation stability and transport height of conveyor belt 1. The specific structure of conveyor belt 1 is existing technology and will not be described in detail here.
[0023] The rear array module 4 is installed above the conveyor belt 1. The camera angle of the rear array module 4 can be tilted downwards or horizontally towards the conveyor belt 1's conveying direction. It is used to capture images of the rear surface of the sheet material on the conveyor belt 1, obtaining an image of the rear surface of the sheet material. The rear array module 4 can be installed above the conveyor belt 1, with its camera angle aligned with the conveyor belt 1's conveying direction and tilted downwards. For a larger camera area, it can be set horizontally. When the sheet material is conveyed to the camera position by the conveyor belt 1, the rear array module 4 captures an image from behind the sheet material, thus obtaining an image of the rear surface of the sheet material.
[0024] The front array module 7 is installed above the conveyor belt 1, with its shooting direction tilted downwards or horizontally away from the conveyor belt 1. It is used to capture the front surface of the conveyed material on the conveyor belt 1, obtaining an image of the front surface. The front array module 7 can be installed above the conveyor belt 1, with its shooting angle tilted downwards or horizontally towards the direction from which the material is conveyed. When the material is conveyed to the shooting position by the conveyor belt 1, the front array module 7 captures an image from the front of the material, thus obtaining an image of the front surface. The front array module 7 and the rear array module 4 capture images from the front and rear surfaces respectively, thus obtaining images of both surfaces. The shooting nodes of the front array module 7 and the rear array module 4 can be achieved by installing sensors at corresponding positions on the conveyor belt 1. These sensors detect the position of the conveyed material on the conveyor belt 1 and send a sensing signal to the control system. The control system then controls the rear array module 4 and the front array module 7 to capture images of the material on the conveyor belt 1. The sensors can be photoelectric emitting and receiving elements, which will not be elaborated here. The rear array module 4 and the front array module 7 can be high-definition cameras, in order to improve the accuracy of the images and meet the inspection requirements. Both the rear array module 4 and the front array module 7 can include a high-definition camera and a supplementary lighting component, which can be mounted on a bracket via a frame. The high-definition camera is used to photograph the front or rear surface of the material, and the supplementary lighting component illuminates the area where the high-definition camera is shooting, thereby increasing the brightness of the shooting location and meeting the needs of defect analysis.
[0025] A line scanning imaging component can be installed above the side of the conveyor belt 1. This component scans and captures images of the side surfaces of the sheet material being conveyed on the conveyor belt 1. By cooperating with the rear array module 4, the front array module 7, and the line scanning imaging component, multiple side surface images of the sheet material can be obtained for detection and analysis. Of course, it is not excluded that only one side or multiple sides of the sheet material can be scanned; this application can meet the detection requirements in all cases. To meet the detection requirements, the line scanning imaging component can include a line scanning camera and a supplementary lighting component. The line scanning camera is installed on the side of the sheet material flow position on the conveyor belt 1, tilted downwards perpendicular to the conveying direction of the conveyor belt 1, and scans and captures images of the conveyed sheet material to obtain side surface images. The supplementary lighting component illuminates the high-definition camera's shooting position to meet the detection requirements. The supplementary lighting component can be a horizontally arranged light strip, or it can include a mounting frame and supplementary lighting units. Multiple supplementary lighting units are linearly fixed on the mounting frame. The mounting frame is rotatable and its protruding edges limit the light emitted by the supplementary lighting units to form a supplementary lighting plane. The mounting frame may include a placement frame and a connecting plate, which together form a gantry structure. The connecting plate is rotatably connected to the mounting plate. Specifically, an arc-shaped through slot may be provided on the connecting plate, and a screw hole may be provided on the mounting plate at the corresponding position. Screws can pass through the arc-shaped through slot and be fixed in the screw hole, thereby fixing the angle of the supplementary lighting component's supplementary lighting plane. Multiple through mounting slots are linearly provided on the placement frame, and the supplementary lighting unit can be placed in the mounting slot and fixed. The light from the supplementary lighting unit passes through the mounting slot to illuminate the light source. The edges of the mounting slots restrict the light from the supplementary lighting unit, preventing excess light from escaping. The line scan imaging component may include a fixed line scan module 5 and a free line scan module 6. The fixed line scan module 5 and the free line scan module 6 are arranged opposite each other on both sides of the material on the conveyor belt 1, with opposite shooting directions, thus enabling imaging of both sides of the material. The fixed line scan module 5 is fixedly installed above the conveyor belt 1, and the free line scan module 6 can slide in the direction perpendicular to the conveyor belt 1 to adjust the shooting position laterally. This allows for adjustment of the distance between the fixed line scanning module 5 and the free line scanning module 6, adapting to the width requirements of the inspected material. The free line scanning module 6 can be laterally driven and slid through the transverse linear module 3, thus accommodating materials of different widths. Specifically, the width of the material can be obtained in advance, and then the control system can control the transverse linear module 3 to move laterally, thereby adjusting the shooting position of the free line scanning module 6 so that its shooting position is always on the side surface of the material. In this inspection structure, edge correction is required before material inspection to ensure that the edge of the material coincides with the shooting position of the fixed line scanning module 5.The transverse linear module 3 can be a synchronous belt drive module, including a linear track, a drive component, and a synchronous belt. The linear track is fixedly installed on the frame to form a transverse linear path, and its two ends are provided with rotating rollers for steering the synchronous belt. The drive component can be a servo motor installed on the linear track or the frame and connected to the drive rollers. The synchronous belt is wound around the rotating rollers and the drive rollers. Under the action of the servo motor, the drive rollers drive the synchronous belt to rotate, thereby completing the linear drive of the synchronous belt on the linear track. The synchronous belt drive module is a prior art and will not be described in detail here. Of course, the line scanning module can also be other forms such as a combination of a motor and a lead screw, which will not be described in detail here. A detection box 2 can be installed on the conveyor belt 1. A gap is provided between the detection box 2 and the conveyor belt 1 for the material to flow through. By setting the detection box 2, the rear array module 4, the front array module 7, and the line scanning imaging component can be surrounded, forming a mounting support while avoiding interference from external light sources to the imaging, and also avoiding light leakage from the supplementary lighting component to cause light pollution, thus ensuring the safety of the equipment. The inspection box 2 can be composed of a frame and an outer casing. The frame can be a support frame formed by welding metal rod-like structures, and the outer casing covers the frame to form the inspection box 2. This structure can improve the aesthetics and safety of the equipment. The inspection box 2 is equipped with an observation window for observing the internal condition of the equipment. Through the observation window, the operation and fault status of the equipment inside the inspection box 2 can be observed. When the conveyor belt 1 is multi-segmented, the inspection box 2 covers the middle position of one segment of the conveyor unit. The observation window of the inspection box 2 can be made of glass, plexiglass, etc., or it can be a combination of a glass plate and an outer frame. The outer frame covers the outside of the glass plate, thereby increasing the safety of the observation window and facilitating assembly and operation. The top of the observation window is hinged to the inspection box 2, facilitating its opening and closing. Opening the window allows for maintenance and repair of the internal components of the inspection box 2, while closing it allows direct observation of the interior. Since both the rear array module 4 and the front array module 7 are angled downwards, light shines onto the conveyor belt 1 and does not pass through the observation window; details will not be elaborated here. Image analysis is not the subject of this application and will not be discussed further.
