Embodiment Construction

[0037] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] A welding stud position detection device based on silhouette technology, such as figure 1 As shown, it includes: a camera 1, multiple point light sources and line lasers 4, the optical axis of the camera 1 is perpendicular to the plane where the object to be measured is located; multiple point light sources and line lasers 4 are arranged above the side of the object to be measured; multiple When the point light source is irradiated, the shadows formed by at least two point light sources irradiating the object to be measured are not on the same straight line. The light emitted by multiple point lights is projected at the working distance directly in front of the camera.

[0039] Preferably, the heights of the multiple point light sources are the same, and the angles between the light rays formed by them and t...

Abstract

The invention discloses a welding stud position detection device based on silhouette technology, which comprises a camera, a plurality of point light sources and a line laser, wherein the optical axisof the camera is perpendicular to the plane on which the object to be measured is arranged; the plurality of point light sources and the line laser are arranged above the side of the object to be measured; shadows formed by at least two point light sources irradiating the object to be measured are not on the same straight line when the plurality of point light sources irradiate; a welding stud detection method is also disclosed, the detection method of the welding stud can calculate the position coordinate information of the welded stud, and has the advantages of high efficiency, convenienceand intelligence.

Description

technical field [0001] The invention relates to the field of visual measurement, in particular to a welding stud position detection device and method based on silhouette technology. Background technique [0002] Stud welding is a widely used connection method, which is widely known in the field of workpiece manufacturing. For example, there are hundreds of welding studs on a car body, which are used to connect various components such as instruments and interiors. It is a very important processing technology in automobile manufacturing. Whether the position of the welding stud is accurate will directly affect the subsequent assembly. Traditional welding stud position detection is realized by manual scale measurement, such as: dial indicator, iron ruler, wedge-shaped feeler gauge, etc., with low measurement efficiency and poor measurement accuracy, which cannot meet the needs of high-efficiency and high-precision automobile production lines. [0003] With the development of ...
