Vision detection device and system

Abstract

The embodiment of the invention discloses a vision detection device and system. The vision detection device disclosed by the embodiment of the invention comprises a rotating platform and a photographic device; the rotating platform is used for locking and rotating a detected part, so that the detected surface of the detected part is aligned to a lens of a camera in the photographic device; a preset distance is reserved between the photographic device and the rotating platform, and the photographic device is used for carrying out image acquisition on the detected surface of the detected part; the rotating platform comprises a base, a horizontal plane X-axis moving module, a horizontal plane Y-axis moving module and a detected surface adjusting module which are connected in sequence in the vertical direction; the detected surface adjusting module is used for locking the detected part and enabling the detected part to rotate by taking a vertical direction as a rotating shaft or enabling the detected part to overturn by taking an X-axis as an overturning shaft, wherein the X-axis is vertical to an optical axis of the lens on the horizontal plane; the horizontal plane X-axis moving module is used for controlling the detected part to move along the X-axis; and the horizontal plane Y-axis moving module is used for controlling the detected part to move along a Y-axis, wherein the Y-axis is vertical to the optical axis of the lens. According to the invention, the performance of the vision detection system can be effectively improved.

Description

technical field [0001] The invention relates to the field of visual inspection, in particular to a visual inspection device and system. Background technique [0002] The detection of product processing quality has developed from the initial manual detection to the modern machine vision detection based on computer graphics. The principle of visual detection is: use a high-precision camera to shoot a certain plane of the tested part, and the computer obtains the captured image Finally, the visual software is compared with the sample picture taken at the same position in advance, and the designated monitoring point is calculated. If the data difference obtained by comparison is within the preset acceptable range, the monitoring point is qualified. If the data difference obtained by comparison is not within the preset acceptable range, the monitoring point is unqualified. [0003] For the inspection of products such as circuit boards, component shapes, and surface quality, it i...

Problems solved by technology

[0006] The manipulator manipulates a product with a large weight (for example, 30 kg) to generate a large inertia during the process of moving, rotating or flipping, which limits the manipulation speed of the manipulator and reduces the test efficiency; manipulators that can manipulate products with a large weight need High cost, and the manipulator needs to occupy a huge space, which does not meet the requirements of online testing on the factory floor
