Description

Technical Field

[0001] The utility model belongs to the technical field of CCD inspection machine equipment, and particularly relates to a CCD vision inspection machine. Background Art

[0002] With the continuous improvement of the scientific and technological level, the industrial production level is also constantly improving, and users' requirements for products in industrial production are getting higher and higher; in the existing industrial production, the detection method of products mostly adopts the manual method to detect products. However, manual detection will lead to poor detection effect of products, resulting in uneven product quality, low detection efficiency, and high cost of the manual detection method.

[0003] In order to solve the deficiencies of the existing technology, people have carried out long-term exploration and put forward various solutions. For example, a Chinese patent document discloses a flexible detection and analysis system for key surfaces and internal defects of castings [201920324364.3], which includes a hardware system and a control system. The hardware system includes a conveyor belt with a frame. An X-ray detection chamber is arranged on the conveyor belt frame. A robotic arm is arranged on one side of the X-ray detection chamber, and a detection bracket is arranged on the other side. A CCD camera and an annular light source are arranged on the detection bracket. Both the CCD camera and the robotic arm are connected to a computer terminal through network cables. A position sensor is arranged on the conveyor belt frame below the annular light source; the other side of the robotic arm is set as a qualified product outlet; a defective product box is arranged directly in front of the robotic arm. The defective product box is arranged on one side of the conveyor belt and has a gap with the conveyor belt; the robotic arm is fixedly connected to the conveyor belt frame; the detection bracket is fixedly connected to the conveyor belt frame; the CCD camera is arranged above the center of the annular light source.

[0004] The above solution solves the problem of poor existing detection effect to a certain extent, but there are still many deficiencies in this solution. For example, when the product is photographed by the CCD camera, it will stop moving to ensure the shooting effect, reducing the detection efficiency. Summary of the Invention
