Description

Technical Field

[0001] This utility model belongs to the field of testing tooling technology, specifically relating to a quality inspection system for the spray coating process of laptop computer casings. Background Technology

[0002] As the laptop market continues to develop, consumers are increasingly demanding higher quality products in terms of appearance. The coating quality of the casing not only affects the overall aesthetics of the product but also directly influences the user's first impression and purchasing decision.

[0003] The inspection of spray coating quality typically includes multiple aspects such as surface smoothness, color uniformity, coating thickness, and the presence of defects (such as bubbles, particles, scratches, etc.). Traditional spray coating quality inspection methods rely on visual inspection by workers, which has many limitations: low efficiency, high cost, and susceptibility to the subjective judgment of inspectors, leading to inaccurate or unstable test results.

[0004] With the development of machine vision and artificial intelligence, automated quality inspection systems based on these technologies have gradually become a hot topic in the industry. High-quality data acquisition is crucial to ensuring the accuracy of subsequent image analysis and defect identification. Current methods primarily involve acquiring images using an industrial camera. This approach is susceptible to lighting conditions and has poor versatility across different colored and material casings, thus affecting the accuracy of subsequent inspection and analysis. Utility Model Content

[0005] The present invention aims to provide a quality inspection system for the spray coating process of laptop casings, which is unaffected by ambient light and has strong versatility.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quality inspection system for the spray coating process of laptop casings includes a support frame with a working surface. A placement plate is rotatably connected to the working surface. The support frame also has several lights of different colors, with the light rays facing the placement plate. The system further includes a camera, a controller, a communication module, and a display. The controller is electrically connected to the lights, camera, communication module, and display. The controller controls the on / off state of each light, controls the camera to take pictures and sends the captured images to a host computer via the communication module, and controls the display to show quality inspection information.

[0008] Furthermore, it also includes a mask, which is cuboid in shape and has opaque fabric on its top and sidewalls.

[0009] Furthermore, the working surface is equipped with a background display screen, and the workpiece to be tested is placed on the background display screen.

[0010] Furthermore, the background display screen is a color e-ink screen.

[0011] Furthermore, it also includes a warning light, which is electrically connected to a controller, and the controller is used to control the opening and closing of the warning light; the warning light includes a green pass indicator and a red fail indicator.

[0012] Furthermore, it also includes an operation panel, and the controller is electrically connected to the operation panel.

[0013] Furthermore, it also includes a motor, the output shaft of which is poweredly connected to the rotating shaft of the placement plate, and the motor is electrically connected to a controller, which is used to control the motor to drive the placement plate to rotate.

[0014] Furthermore, the placement plate is equipped with suction cups, which are connected to the placement plate via metal flexible tubing.

[0015] Furthermore, a color card tray is provided on the working surface, and color cards are placed in the color card tray.

[0016] Furthermore, the communication module includes a wireless communication module, which is a WIFI module.

[0017] Technical principles and beneficial effects of this technical solution:

[0018] 1. Different lighting conditions and viewing angles can affect color perception and the visibility of surface defects. The technical solution of this application can capture images of workpieces from multiple angles under various lighting conditions to obtain the most realistic spraying effect and improve detection accuracy.

[0019] 2. Using a color e-ink screen as a background allows you to set a corresponding background color based on the different colors of the casing, thus making the casing being photographed stand out more. The e-ink screen itself does not emit light and does not affect the shooting effect. Setting different colored lights can also simulate different lighting conditions in different environments, making it suitable for quality inspection of casings of different colors and materials.
