Description
Technical field
The present invention relates to a kind of straight line laser technology, especially a kind of laser automatic graticule technology, the equipment of a kind of laser level light Self-regulation track.
Background technology
It is known that, laser level is a kind of novel optical, mechanical and electronic integration instrument, it uses 635nm laser diode mostly, visible red horizontal straight line and vertical straight line can be projected on metope, utilize the automatic compensator of instrument internal or the manual horizontalization of plate level can keep level (or vertical) position of laser projection line.It is mainly used in interior decoration, erection of doors and windows, pipe installation, tunnel piercing, hangs in vertical line and the construction such as quality inspection and project supervision.New pattern laser level is different from conventional calibration instrument in principle, and its required precision is also higher than tradition level, so its actual production and the light precision regulating method during using and device cause the concern of more and more Chinese scholars.
Laser level mainly needs the index of calibration to include one or the horizontal horizontal accuracy of 1-2 bar, 1-4 bar vertical line orthogonal precision horizontal with 1-2 bar, the orthogonal precision of 1-4 bar vertical line, the linearity of laser rays, lower to a precision with the automatic compensation precision etc. of instrument.
Existing laser level light adjustment is mainly manually adjustment, measure the Parallel errors between horizontal laser light horizontal line, vertical line and datum line respectively, according to the data measured, manually carry out tightening and unscrew the bolt on light regulating block, thus light regulating position, until it reaches required precision.Calibration equipment in this kind of adjusting process can solve the light adjustment problem of laser level very well, but also some drawback: 1) with spirit level, plumb bob messenger wire horizontal and vertical benchmark the most, precision is relatively low；2) process of light regulation is relatively complicated, takes long enough.
The light adjustment of laser level is broadly divided into two pieces: light adjustment detects with light, existing laser level light calibration apparatus the most still utilizes artificial adjustment, the light of laser level is detected, the existing detection mode at digital camera, such as a kind of laser demarcation device calibration system of Application No. 201310491282.5, it includes base, support, 8 sampling light pipes；Support is fixed on base, and sampling light pipe is fixed on support；Each sampling light pipe all includes parallel light tube, digital camera, camera lens abutment sleeve, light pipe box, parallel light tube is fixed on support by light pipe box, camera lens abutment sleeve is fixed on parallel light tube, and digital camera passes sequentially through interface conversion part, lens sleeve is connected with camera lens abutment sleeve；Digital camera front end is provided with USB interface；The present invention is combined with technology such as light pipe tiny angle measurement, machine vision metrology technology, data fusion and laser level carries out accuracy detection and calibration, and testing result can quantify, stores and build library management.This detection device achieves real-time ray position detection, and precision is the highest, but the function of only detection, and the adjustment of light needs for manually having gone.The regulation of existing light calibration apparatus is relatively complicated, the method being automatically adjusted such as the Chinese patent laser level light of Application No. 201310708136.3, comprises the following steps: laser instrument is loaded on the laser socket of adjustable ray position by (1)；(2) two balls are put into the ball recess on movement；(3) laser socket is arranged on movement, installs two position adjustments bolts and two angle adjustable bolt simultaneously；(4) turning on the power, light launched by laser instrument, the physical location of three linear CCD sensor monitoring light by being placed on one meter of outer same straight line；(5) by linear CCD sensor, the current location of light being fed back to industrial control computer, industrial control computer sends pulse to servomotor；(6) driven by servomotor hexagonal floating spanner, regulates entering and moving back of two position adjustments bolts and two angle adjustable bolt, thus adjustment laser beam position.Its a fly in the ointment is, light calibration apparatus uses industrial computer and four motors to be adjusted, and each motor individually regulates bolt, controls loaded down with trivial details, and motor controls poor synchronization, is unfavorable for accurately controlling, and production cost is higher.
Apparatus of the present invention are on the basis of existing laser level light adjustment mechanism; servomotor is utilized to carry out Self-regulation track ray position and gradient; and utilize digital camera to carry out the position detection of light, it is achieved the Self-regulation track of laser level light, and adjusting accuracy is higher.
Servomotor can accurately control turned position and the speed of main shaft.Servo motor rotor rotating speed is by input signal control, and energy fast reaction, in automatic control system, as executive component, and has the characteristics such as electromechanical time constant is little, the linearity is high, pickup voltage.Can be used as in the method regulating the executing agency regulating bolt on laser socket.
Digital camera is a kind of to utilize electronic sensor that optical image is converted into the camera of electronic data.The principle that digital camera and ordinary camera chemical change by silver bromide on film records image is different, and the sensor of digital camera is charge-coupled device (CCD) or the complementary metal oxide semiconductors (CMOS) (CMOS) of a kind of photoinduction formula.Digital camera can be placed in this device the particular location of detection laser beam.
By the retrieval to domestic and international patent document, do not find laser level light self-checking device based on digital camera at present, present invention firstly provides this adjusting means.

3, regulation handle 309, mobile station 307 is advanced, and makes each regulation spanner coordinate with corresponding regulation bolt.
Starting regulation, regulating step is as follows:
1) PC is according to the feedback of digital camera, first determines whether the ray position feedback on the digital camera 2 of centre, and compares the target location of current feedback position with setting；
2) if the ray position of sandwich digit camera 2 detection is on target location, then single-chip microcomputer sends positive pulse to corresponding servo-driver, and lower position adjustments bolt is tightened, and upper position adjustments bolt is unscrewed, and light moves down；
3) if the ray position of sandwich digit camera 2 detection is under target location, then single-chip microcomputer sends negative pulse to corresponding servo-driver, and lower position adjustments bolt is unscrewed, and upper position adjustments bolt is tightened, and light moves up.
After the ray position of detection arrives the target location set on middle digital camera 2, then carrying out the angular adjustment of light, regulating step is as follows:
1) PC is according to the feedback on Contemporary Digital camera, it is judged that the ray position feedback of two, left and right digital camera 1 and digital camera 3；
2) if during the ray position Right deviation of digital camera feedback, then single-chip microcomputer sends negative pulse to corresponding servo-driver, and lower angle regulation bolt is unscrewed, and upper angle regulation bolt is tightened, and light is gradually adjusted to horizontal level；
3) if during the ray position "Left"-deviationist of digital camera feedback, then single-chip microcomputer sends positive pulse to corresponding servo-driver, and lower angle regulation bolt is tightened, and upper angle regulation bolt is unscrewed, and light is gradually adjusted to horizontal level.So repeatedly regulate, finally make light reach target location.Ray position regulation schematic diagram is as it is shown in figure 5, light angle regulates schematic diagram as shown in Figure 6.
