Description

Technical Field

[0001] The utility model relates to the technical field of aircraft component detection, in particular to an aircraft component aperture detection mechanism. Background Art

[0002] In the aircraft manufacturing process, the aperture detection of parts is a key link to ensure the safety performance of the aircraft. At present, there are many aperture detection solutions on the market. The most common solution is to directly measure the aperture through mechanical measuring equipment. However, this traditional method has obvious disadvantages: first, the measurement accuracy is limited by the accuracy and stability of the mechanical equipment; second, the measurement process is cumbersome, inefficient, and easily affected by human factors; third, for apertures with complex shapes, traditional mechanical measurement methods are difficult to apply.

[0003] Therefore, it is necessary to develop a new type of aircraft parts aperture detection mechanism to improve the detection accuracy and efficiency, reduce the influence of human factors, and adapt to the detection needs of complex-shaped apertures. Utility Model Content

[0004] The utility model aims to provide an aperture detection mechanism for aircraft parts to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aircraft parts aperture detection mechanism, comprising a chassis, a conveyor belt and a visual sensor, a controller is installed on the front side of the chassis, a conveyor belt is arranged on the top of the chassis, a bracket is fixedly installed at the top rear end of the chassis, a visual sensor is installed above the front of the bracket, a display screen is installed on the top side of the chassis through a mounting frame, and a base plate is arranged at the bottom of the display screen through the mounting frame.

[0006] When the device is running, the staff places the aircraft parts on the conveyor belt, which transports the aircraft parts to the bottom of the visual sensor. The visual sensor takes pictures of the aircraft parts to obtain image information of the aperture of the aircraft parts. The visual sensor has high resolution and high sensitivity, and can capture the subtle features of the aperture, providing an accurate data basis for subsequent algorithm analysis. After obtaining the image information, the visual sensor transmits the data to the controller. The controller receives the image information and runs a pre-set algorithm to analyze the aperture. It can calculate the actual size, shape deviation and other parameters of the aperture based on the extracted feature information, and compare them with the preset standard values ​​to determine whether the aperture is qualified. Finally, the controller outputs the analysis results to the display screen in a visual way for display, and provides corresponding feedback signals. If the aperture is unqualified, the display screen can display the data to remind the operator to process it.

[0007] Preferably, a positioning frame is installed below the front surface of the bracket, and a through hole is opened inside the positioning frame.

[0008] By using positioning frames and through holes, visual sensors can pass through the positioning frames to take pictures of aircraft parts, while the positioning frames can block images other than the aircraft parts, making the image purer and easier for the machine to perform algorithm recognition.

[0009] Preferably, a servo motor is provided on the front side of the conveyor belt, and the servo motor is electrically connected to the controller.

[0010] The servo motor can control the speed and position with high accuracy. It can convert the voltage signal into torque and speed to drive the control object. The controller can control the servo motor to start and stop precisely. The conveyor belt uses the servo motor as the power source to control the aircraft parts on the conveyor belt to move to the specified position.

[0011] Preferably, a digital display screen is provided on the top of the controller, and a button is installed on one side of the top of the controller.

[0012] The digital display screen can show the operating parameters of the controller, and the staff can set the operating parameters of the controller through buttons. The coordinated use makes it convenient for the staff to use the chassis through the controller.

[0013] Preferably, two sets of casters are installed on both sides of the bottom of the chassis.

[0014] The chassis can be moved by casters, making it convenient for staff to move the device to a designated location for use.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] The present application can achieve high-precision measurement of aperture through visual sensors and algorithm analysis, avoiding the accuracy limitations and stability problems that may exist in mechanical measuring equipment. It is suitable for apertures of various shapes and sizes and has strong versatility and adaptability. It adopts automated detection methods without the need for human intervention, greatly improving detection efficiency and reducing production costs. At the same time, it can realize automatic judgment and feedback of aperture, improving the level of intelligence of detection. BRIEF DESCRIPTION OF THE DRAWINGS

However, after understanding the disclosure of the present application, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent. For example, the order of operations described herein is merely an example, and is not limited to the order set forth herein, but in addition to the operations that must occur in a particular order, changes that will be apparent after understanding the disclosure of the present application may be made. In addition, in order to improve clarity and brevity, descriptions of features known in the art may be omitted.

[0023] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0024] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0025] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0026] Although terms such as "first", "second", and "third" may be used herein to describe various components, assemblies, regions, layers, or portions, these components, assemblies, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one component, component, region, layer, or portion from another component, component, region, layer, or portion. Therefore, without departing from the teachings of the examples described herein, the first component, component, region, layer, or portion referred to may also be referred to as the second component, component, region, layer, or portion.

[0027] For ease of description, spatial relative terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another element as shown in the drawings. Such spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, an element described as being "above" or "upper" relative to another element would then be located "below" or "lower" relative to the other element.

[0028] Therefore, the term "above" includes both "above" and "below" orientations depending on the spatial orientation of the device. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative terms used herein will be interpreted accordingly.

[0029] The terms used herein are only used to describe various examples and are not used to limit the present disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms "include", "comprise" and "have" list the stated features, quantities, operations, components, elements and / or their combinations that exist, but do not exclude the existence or addition of one or more other features, quantities, operations, components, elements and / or their combinations.

[0030] Variations in the shapes shown in the drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include variations in shapes that occur during manufacturing.
