Abstract
The invention relates to a plain butt weld detection system based on a dual-path converged adjustable light path. The plain butt weld detection system comprises an imaging device and an image controller, wherein the image controller is connected with the imaging device; two light source generation devices are symmetrically arranged on both sides of the imaging device, can rotate at a certain angle with a vertical direction; light rays emitted from the light source generation devices pass through a detected plate to enter the imaging device, the imaging device transmits an image to the image controller, and the image controller processes the received image to obtain a high-definition weld detection image. The detection system disclosed by the invention realizes the detection illumination of a plain butt weld by utilizing the dual-path converged light path, thereby enhancing the illumination intensity and eliminating the influence of a shadow generated through a single-path light irradiation weld on the detection of a weld position; the light path is changed by adjusting the angles of the light sources and the adjustment of the optimal incident angle of the light path before convergence can be realized, so that the weld illumination of different positions can be realized and an clearly imaged weld image is obtained.
Description
Technical field
The present invention relates to weld seam detection field, be specially a kind of plain butt weld seam detection system of assembling adjustable light path based on two-way.
Background technology
In Automation of Welding field, usually need the thin plate class weld seams such as aluminium sheet, corrosion resistant plate to carry out automatic welding, the common square groove of such weld seam, weld gap is Huo little gap, zero stand-off (within 0 ~ 1mm), and all higher (detection time, accuracy of detection was within the 0.05mm within 0.05s) of requirement of real-time, precision and reliability that butt welded seam detects.Adopt conventional line-structured light weld seam detection because of the feature of weld seam own little, the impact being easily interfered, be difficult to realize in real time, effectively, high precision detects reliably, has affected the development of such weld joint automatized solder technology.
Summary of the invention
For the shortcoming of above-mentioned prior art, the invention provides a kind of weld image that can effectively obtain high-contrast, realize square groove weld seam detection based on two-way, assemble the plain butt weld seam detection system of adjustable light path.
The present invention solves the problems of the technologies described above by the following technical solutions: a kind of plain butt weld seam detection system of assembling adjustable light path based on two-way, comprise imaging device and connected image controller, in described imaging device symmetria bilateralis, two light source generators are set, described light source generator can rotate into certain Angle with vertical direction, the light that described light source generator penetrates through tested drafting board laggard enter described imaging device, imaging device sends the picture becoming out to described image controller, image controller obtains high definition weld seam detection image after the picture of receiving is processed.
As preferably, described imaging device is CCD camera or CMOS camera.
As preferably, the angle ranging from 20 degree～45 degree.
As preferably, the camera lens face of the center of described two light source generators and described CCD camera or CMOS camera is in same level.
The present invention compared with prior art tool has the following advantages: utilize two-way Path of Convergent Rays to realize the detection illumination of square groove weld seam, not only can increase intensity of illumination, can also eliminate the impact of the shade butt welded seam position probing of single channel irradiation weld seam generation; By adjusting the Angulation changes light path of light source, realize the adjustment of the incident angle before light path is assembled, obtain the incident angle of imaging definition the best; By adjusting the Angulation changes light path of light source, realize the change of convergent point, can realize the weld seam illumination of diverse location; When the convergent point of two light paths is near position while welding, and its angle is that 20 degree～45 can obtain higher weld image while spending.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram and embodiment, further set forth the present invention.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
With reference to figure 1, the embodiment of the present invention provides a kind of plain butt weld seam detection system of assembling adjustable light path based on two-way, comprise imaging device 1 and connected image controller 3, described imaging device is CCD camera or CMOS camera, in described imaging device 1 symmetria bilateralis, light source generator 21 and light source generator 22 are set, the camera lens face of the center of described two light source generators and described CCD camera or CMOS camera is in same level, described light source generator 21 can with the vertical direction α that rotates into certain Angle, described light source generator 22 can with the vertical direction β that rotates into certain Angle, α and β be 20 degree～45 degree preferably, light source generator 21 penetrates light 210, light source generator 22 penetrates light 220, light 210 and light 220 are focused at weld seam 00 place of tested drafting board 0, reflection ray 10 is injected imaging device 1 imaging again, imaging device 1 sends the picture becoming out to described image controller 3, image controller 3 obtains high definition weld seam detection image after the picture of receiving is processed.
In the present invention, first need to detect the aluminium sheet of weld seam, corrosion resistant plate or other thin plates lie in a horizontal plane under this detection system, the camera lens of the weld seam that needs are detected to good CCD camera or CMOS camera, open the light source generator that is symmetricly set on CCD camera or CMOS camera both sides, light source generator penetrates light, then the angle of two light source generators and vertical direction is adjusted in rotation, two-beam is assembled in the commissure of thin plate, its reflected light is through optical lens imaging on CCD camera or CMOS camera of CCD camera or CMOS camera, CCD camera or CMOS camera send the picture becoming out to described image controller, image controller obtains the weld image of high-contrast after the picture of receiving is processed.Again by adjusting angle [alpha] and the angle of β capable of regulating incident light and the position of convergent point of two light sources, thereby to the weld seam of diverse location, can obtain the image of high-contrast, in order to reach good detection effect, article two, the convergent point of light path should be near position while welding, and its angle should be between 20 degree～45 degree.This detection system utilizes two-way Path of Convergent Rays to realize the detection illumination of square groove weld seam, not only can increase intensity of illumination, can also eliminate the impact of the shade butt welded seam position probing of single channel irradiation weld seam generation; By adjusting the Angulation changes light path of light source, realize the adjustment of the incident angle before light path is assembled, obtain the incident angle of imaging definition the best; By adjusting the Angulation changes light path of light source, realize the change of convergent point, can realize the weld seam illumination of diverse location.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention; the technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
