Description

Technical Field

[0001] The utility model relates to the technical field of machine vision, in particular to a measuring device for machine vision. Background Art

[0002] Machine vision is the process of giving machines visual perception, enabling them to have scene perception capabilities similar to biological visual systems. It obtains a lot of information about the surrounding environment through visual perception, and uses machines instead of human eyes to make measurements and judgments. It has become a development trend in many related fields.

[0003] When optimizing existing measuring devices for machine vision, most of them are reflected in enabling the equipment to detect multiple items and complex objects at the same time. For example, the Chinese utility model patent with application number CN201920270616.9 discloses "A multi-axis robotic arm based on a multi-functional inspection module". In this device, a robotic arm, a mobile trolley and a communication module are arranged on the robotic arm. A multi-functional inspection module is threadedly installed on the end of the robotic arm, which solves the problem that the existing inspection cannot detect multiple items and complex objects at the same time, resulting in poor inspection flexibility and low efficiency. It achieves the effect of automatic and flexible diversified collection and collection of complex objects, and is highly practical.

[0004] Although the aforementioned machine vision measuring devices have certain advantages in simultaneously inspecting multiple items and complex objects, they still have certain disadvantages: the devices are usually equipped with indicator lights to assist in measurement and inspection operations. When the devices are not in use, the indicator lights are usually exposed to the outside. Without protection, they can easily be accidentally hit and shattered, or exposed to the outside and attract dust from the air, forming a cumulative layer covering the outside of the light, affecting its lighting brightness range and clarity.
