[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, 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 of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses. Example

[0016] refer to Figure 1-Figure 2 In this embodiment, a plate edge banding detection device is proposed, which is used to detect the plate after edge banding, or detect the edge defects of the plate. The plate edge banding detection device includes: The conveyor belt 1 is used to convey the plate. The conveyor belt 1 needs to convey smoothly and reduce the up and down shaking of the plate during the conveying process, so as to ensure the accuracy of the detection. Generally, the conveyor belt 1 is set horizontally, which can not only be very beneficial to the detection of the plate, but also better control the transmission of the plate. Of course, some small-angle tilt settings cannot be ruled out, and the details are not repeated here. In order to better improve the detection accuracy, the conveyor belt 1 can include a plurality of conveying units, and each conveying unit is sequentially docked on the same plane end to end in the conveying direction, so as to form a segmented transmission. Through the segmented setting, the transmission length of each conveying unit can be shortened, and this method can increase the stability of the transmission. Each conveying unit can be installed on a bracket, and the bracket forms a supporting base to ensure the installation stability and transmission height of the conveyor belt 1. The specific structure of the conveyor belt 1 is the existing technology and is not repeated here.

[0017] The rear array module 4 is installed above the conveyor belt 1, and the shooting direction of the rear array module 4 can be tilted downward or horizontally toward the conveying direction of the conveyor belt 1, and it is used to shoot the rear side of the plate on the conveyor belt 1 to obtain the image of the rear side of the plate. The rear array module 4 can be installed above the conveyor belt 1, and its shooting angle can be consistent with the conveying direction of the conveyor belt 1 and tilted downward, and the shooting range can be set horizontally. When the plate is transported to the shooting position under the action of the conveyor belt 1, the rear array module 4 shoots from the back of the plate, so that the image of the rear side of the plate can be obtained.

[0018] The front array module 7 is installed above the conveyor belt 1, and the shooting direction is tilted downward or horizontally facing away from the conveying direction of the conveyor belt 1. It is used to shoot the front side of the plate conveyed on the conveyor belt 1 to obtain the image of the front side of the plate. The front array module 7 can be installed above the conveyor belt 1, and its shooting angle can be tilted downward or horizontally facing the direction of the conveyor belt 1. When the plate is conveyed to the shooting position under the action of the conveyor belt 1, the front array module 7 shoots from the front of the plate, so that the image of the front side of the plate can be obtained. The front array module 7 and the rear array module 4 shoot from two more sides, the front side and the rear side, respectively, so that the images of the front and rear sides can be obtained. The shooting nodes of the front array module 7 and the rear array module 4 can be installed with sensors at the corresponding positions of the conveyor belt 1, and the sensors can sense the position of the plate conveyed on the conveyor belt 1, so that the sensing signals can be sent, and the sensing signals are sent to the control system, and then the control system controls the rear array module 4 and the front array module 7 to shoot the plate on the conveyor belt 1. The sensor can be a photoelectric transmitting and receiving element, and the specific details are not repeated here. The rear array module 4 and the front array module 7 can be high-definition cameras. Of course, in order to improve the accuracy of shooting and meet the detection requirements, the rear array module 4 and the front array module 7 can both include a high-definition camera and a fill light component, which can be installed on the bracket through a frame; the high-definition camera is used to shoot the front or back side of the plate, and the fill light component is directed toward the shooting position of the high-definition camera for fill light irradiation, thereby improving the brightness of the shooting position, thereby meeting the defect analysis requirements.

[0019] A line scanning shooting component may be provided above the side of the conveyor belt 1, and the line scanning shooting component is used to line scan the side surface of the plate conveyed on the conveyor belt 1 to obtain a side surface image. Through the cooperation of the rear array module 4, the front array module 7 and the line scanning shooting component, multiple side surface images of the plate can be obtained, and they can be detected and analyzed. Of course, it is not excluded that only one side or other multiple sides of the plate are set, and the present application can meet the detection requirements. In order to meet the detection requirements, the line scanning shooting component may include a line scanning camera and a fill light component. The line scanning camera is installed on the side of the plate flow position of the conveyor belt 1, and can be tilted downward in the vertical conveying direction of the conveyor belt 1 and scan and shoot the transmitted plate to obtain the side surface image of the plate. The fill light component performs fill light irradiation toward the shooting position of the high-definition camera, thereby meeting the detection requirements. The fill light component can be a horizontally arranged light strip, and of course it can also include: a mounting frame and a fill light unit. The fill light unit is arranged in multiples and linearly fixedly installed on the mounting frame. The mounting frame can be rotatably installed, and the light emitted by the fill light unit is limited by the protruding edge to form a fill light plane. The mounting frame may include a placement frame and a connecting plate, the placement frame and the connecting plate form a gantry structure, the connecting plate can be rotatably connected to the mounting plate, specifically, an arc-shaped through groove can be opened on the connecting plate, and a screw hole can be opened at the corresponding position of the mounting plate, and the screw can pass through the arc-shaped through groove and be fixed in the screw hole, so as to complete the angle fixation of the fill light plane of the fill light component. The placement frame is linearly provided with a plurality of through mounting grooves, the fill light unit can be placed in the mounting groove and fixed, the light of the fill light unit passes through the mounting groove to complete the irradiation, and the edge of the mounting groove limits the light of the fill light unit to prevent excess light from leaking out. The line scanning shooting component may include: a fixed line scanning module group 5 and a free line scanning module group 6, the fixed line scanning module group 5 and the free line scanning module group 6 are arranged oppositely, and are located on both sides of the plate on the conveyor belt 1, and the shooting directions are opposite, so that the side surfaces of the plate on both sides can be shot. The fixed line scanning module group 5 is fixedly installed above the conveyor belt 1, and the free line scanning module group 6 can slide in the conveying direction of the vertical conveyor belt 1 to adjust the shooting position horizontally. Thus, the distance between the fixed line scanning module group 5 and the free line scanning module group 6 can be adjusted to meet the width requirements of the detection plate. The free line scanning module group 6 can be driven to slide laterally by the transverse linear module 3, so that it can be suitable for plates of different widths. Specifically, the width of the plate can be obtained in advance, and then the transverse linear module 3 can be controlled by the control system to move laterally, so as to adjust the shooting position of the free line scanning module group 6, so that the shooting position of the free line scanning module group 6 is always on the side surface of the plate. Under this detection structure of the present application, it is necessary to perform edge correction before the plate is detected so that the edge of the plate coincides with the shooting position of the fixed line scanning module group 5.The transverse linear module 3 can be a synchronous belt drive module, including a linear track, a drive assembly and a synchronous belt; the linear track is fixedly mounted on the frame and forms a transverse linear path, and rotating rollers for the synchronous belt steering are arranged at both ends thereof, and the driving assembly can be a servo motor mounted on the linear track or the frame, and connected to a driving roller, and the synchronous belt is wound around the rotating roller and the driving roller. Under the action of the servo motor, the driving roller drives the synchronous belt to rotate, thereby completing the linear drive of the synchronous belt on the linear track. The synchronous belt drive module is specifically a prior art, and the details are not repeated here. Of course, the line scanning module can also be other forms such as a motor and a screw rod combination structure, and the details are not repeated here. The conveyor belt 1 can be installed with a detection box 2, and a gap for the plate to flow is set between the detection box 2 and the conveyor belt 1. By setting the detection box 2, the rear array module 4, the front array module 7 and the line scanning shooting component can be surrounded, and the installation support can be formed while avoiding the interference of external light sources on the shooting, and also avoiding the leakage of light from the fill light component to cause light pollution, thereby ensuring the safety of the equipment. The detection box 2 may be composed of a frame and an outer structure. The frame may be a support frame formed by welding a metal rod-shaped structure, and then the outer structure covers the periphery of the frame to form the detection box 2. This structure can improve the aesthetics and safety of the equipment. The detection box 2 is provided with an observation window for observing the internal conditions of the detection box 2. The operation and fault conditions of the equipment inside the detection box 2 can be observed through the observation window. When the conveyor belt 1 is multi-stage, the coverage range of the detection box 2 is the middle position of a section of the conveying unit. The observation window detection box 2 may be a glass plate, a plexiglass plate, etc., or may be a combination of a glass plate and an outer frame edge. The outer frame edge is coated on the periphery of the glass plate, thereby increasing the safety of the observation window and facilitating assembly and operation. The top of the observation window can be connected to the detection box 2 by a hinge, so that it is easy to open and close. The components inside the detection box 2 can be maintained and repaired by opening the observation window, and the inside of the detection box 2 can be directly observed by closing the observation window. Since the rear array module 4 and the front array module 7 are both tilted downward, the light is irradiated on the conveyor belt 1 and does not pass through the observation window. The details are not repeated here. Image analysis is not the subject of protection of this application, and the details are not repeated here.
