Discuss.
Fig. 1 shows structural representation of the present utility model.The propagation trajectories of where the dotted line signifies that laser.
This utility model is the device for the depth information and width information measuring weld seam, during use
Can be connected with the host computer of such as computer, this device can be transmitted by data after measuring
Interface sends measurement data to host computer, in order to host computer according to measure data result to machinery
Send control signal and move directly over welding material to control welding gun.
As it is shown in figure 1, weld measurement device includes generating laser the 11, first lens 12, second
Lens 13, imageing sensor 14, image processor 15 and data transmission interface 16.
First lens 12 are arranged on the axis direction at generating laser 11 place.The mesh so arranged
Be so that the laser that generating laser 11 launches can be thrown by the convergence effect of the first lens 12
It is mapped on object under test 20.First lens 12 can be convex lens, it is therefore an objective to enables laser to converge,
Reduce loss of light source, so that measurement result is more accurate.Wherein generating laser 11 can be infrared
Generating laser, it is also possible to for visible laser emitter.
Second lens 13 are arranged on the axis direction at imageing sensor place.The purpose so arranged
It is so that laser that generating laser 11 launches is after the reflection of object under test 20, it is possible to
Convergence effect through the second lens 13 projects on imageing sensor 14.Second lens 13 can be
Convex lens, it is therefore an objective to enable laser to converge, reduces loss of light source, so that measurement result is more accurate
Really.Wherein imageing sensor can be array image sensor, it is also possible to for line scan image sensor.
The sampled output mouth of imageing sensor 14 is connected with the sampling input port of image processor 15.
Imageing sensor 14 receives reflection light, and converts optical signals to the signal of telecommunication, then defeated by sampling
Go out port and the signal of telecommunication is transferred to the sampling input port of image processor 15, in order to image processor
15 are further processed according to the signal of telecommunication.
The signal of telecommunication that sampling is obtained by image processor 15 processes, according to the every ginseng in waveform
Number judges width and the depth information of weld seam.Judge that width and depth information belong to according to waveform
Any technique commonly known, is not described in detail herein.

Fig. 2 shows the structural representation that the novel device of this use is observed from another angle.
As in figure 2 it is shown, weld measurement device can also include plane mirror 31 and motor 32.Wherein
Motor drives plane to do dead axle motion.Plane mirror 31 is arranged on the axis of generating laser.
The purpose so arranged is so that the light that laser beam emitting device sends can pass through plane mirror 31
Reflection be irradiated to position as much as possible in weld seam, so can be bigger with sample range, obtain
Measurement result the most accurate.
The frequency that motor 32 drives plane mirror 31 to rotate can control between 5hz to 20hz.
In one embodiment, it is possible to use the mode of point-to-point measurement, can be by when measuring a surface
According to certain distributed enough sampled points are set, measure the depth data of each sampled point successively,
Then interpolation method is utilized to draw the fitting data on whole surface.This metering system substantially butt welded seam
Cross section be scanned measure.The cross section information of weld seam includes width and depth information, as long as measuring
Width that each moment is corresponding and depth information, it becomes possible to obtain the information in whole cross section.Image sensing
On device in as reflecting the change of weld penetration information, when the depth information of weld seam does not changes
Time, the position the most just representing light imaging on the image sensor does not changes.In butt welding
When seam measures, light presents cyclically-varying, light Electrical change in the cycle on the image sensor
Time be exactly the time that light beam scans whole weld seam, then record motor speed, just can calculate whole
The width of weld seam and depth information.
Although specific embodiments more of the present utility model being described in detail by example,
But it should be appreciated by those skilled in the art, example above is merely to illustrate rather than be
Restriction scope of the present utility model.It should be appreciated by those skilled in the art, can be without departing from this reality
