Description

Technical Field

[0001] The present application relates to the technical field of product quality inspection and data archiving, and in particular to a product appearance inspection and archiving component. Background Art

[0002] In modern manufacturing, product appearance quality control is crucial. Whether it's electronic equipment, mechanical components, or everyday consumer goods, the integrity, consistency, and aesthetics of their appearance directly impact the product's market competitiveness and customer satisfaction. For most meteorological products, such as blades, wind cups, and other external weather-sensing components, appearance inspections can be used to determine the dimensional accuracy and assembly precision.

[0003] Appearance accuracy testing of meteorological products requires taking photos of multiple views of the product at fixed positions and angles, and comparing them with target samples for direct computer recognition and judgment. However, existing appearance inspection lines only install 2 to 3 cameras next to the assembly line and use trigger modules to take fixed-point photos. The images cannot meet the requirements of appearance accuracy such as size, and the appearance inspection results are unsatisfactory. Utility Model Content

[0023] In modern manufacturing, product appearance quality control is crucial. Whether it's electronic equipment, mechanical components, or everyday consumer goods, the integrity, consistency, and aesthetics of their appearance directly impact the product's market competitiveness and customer satisfaction. For most meteorological products, such as blades, wind cups, and other external weather-sensing components, appearance inspections can be used to determine the dimensional accuracy and assembly precision.

[0024] Appearance accuracy testing of meteorological products requires taking photos of multiple views of the product at fixed positions and angles, and comparing them with target samples for direct computer recognition and judgment. However, existing appearance inspection lines only install 2 to 3 cameras next to the assembly line and use trigger modules to take fixed-point photos. The images cannot meet the requirements of appearance accuracy such as size, and the appearance inspection results are unsatisfactory.

The two side panels 3 can be completely identical or partially identical, and a gap can be provided between the side panels 3 and the conveyor belt 1 to avoid unnecessary friction between the conveyor belt 1 and the side panels 3 during transportation.

[0029] Please refer to Figure 1 The top plate 4 is disposed above the conveyor belt 1 and is fixedly connected to the two side plates 3. The top plate 4 extends along the first direction 11, and the surface of the top plate 4 is arranged parallel to the conveyor belt 1. The top plate 4 can be a flat plate and can be installed on top of the side plates 3 or at any position above the side plates 3. The top plate 4 can be a flat plate or an inclined plate. The bottom surface of the top plate 4 can be designed to be parallel to the belt surface of the conveyor belt 1, or it can be set at a certain angle, such as within a tolerance range of 15°, which can also achieve the desired purpose.

The two extension plates 5 are spaced apart along the first direction 11, and the spacing between the two extension plates 5 is greater than the length of the product 2 along the first direction 11. The extension plates 5 extend in the height direction. The extension plates 5, the top plate 4, and the side plates 3 can all have the same shape and material. The extension plates 5 can extend in the vertical direction or in the direction toward the conveyor belt 1. The extension plates 5, the top plate 4, and the side plates 3 can be arranged perpendicularly to each other.

Information can be stored using appropriate storage devices, such as hard disks or cloud drives. Image comparison can be achieved using an image comparison algorithm, using a simple absolute difference method (calculating the sum of the absolute values ​​of the differences at each pixel) or a mean square error method (calculating the mean of the sum of the squares of the differences) to measure the differences between images.

[0037] Please refer to Figure 1 Alternatively, we can extract image features, such as edges, corners, and texture features, and then compare the feature vectors of the two images to determine the similarity of the images by calculating the distance between the features (such as the Euclidean distance).

[0041] The controller 63 is a device used to manage, regulate, and control the operation of other devices or systems. It receives input signals (such as sensor data, user operating instructions, etc.), processes them according to predetermined rules and algorithms, and then outputs signals to adjust the behavior of the controlled object, thereby controlling the start and stop of the fill light 62 and the camera. It can adopt a microcontroller 63, FPGA, etc., or a PLC or other logic controller 63.

[0042] The fill light 62 is a device for supplementing light, which can supplement the light for the product 2 and reduce the color difference of the collected image, so that the comparison result is accurate. The fill light 62 in this solution can be a fluorescent lamp, a tungsten lamp or an LED lamp; the fill light 62 can be a flash lamp, which flashes according to the startup of the collection camera 61, and can also be controlled by the controller 63, turned on before the collection camera 61 collects the image, and turned off after the image collection is completed.
