Abstract
The utility model discloses an automatic error detector for a laser instrument, which is used for construction. Scanning beams are emitted by a measured laser instrument which is arranged on a rotary work platform (9) and are converged on a CCD image sensor (5) through a long focus optical lens instrument (1), the images of the scanning laser beams enter into a computer (7) for processing through an image collecting card (6), and then, a tilt error and a cone angle error can be computed. Different accessories are additionally arranged on the rotary work platform (9), and the compensating error, the plumbed error or the plumbing error of other laser instruments can be detected. The utility model has the advantages of small size, strong vibration resistance and high detection efficiency, which is suitable for the automatic error detection of various laser instruments for construction.
Description
The utility model relates to a kind of error automatic detection device of laser device, is mainly used in the dress school of laser device production for building such as Geoplane, laser plummet apparatus, laser plummet, laser level and laser level chi and the legal system measurement verification of factory inspection and measurement verification department.
Along with the development of semiconductor laser with ripe, be that the laser device various for building of representative is used widely with the Geoplane.At present droop error, cone angle error and compensating errors that adopt " two bar methods ", " surveying the chi method for three " or " four bar methods " detection laser instrument more.These detection methods are similar to the laser device use-pattern, carry out on long checkout area, generally need 2～3 people to cooperate, even use intercom work, and the length that takes up room is subjected to interference big, and detection time is long, and efficient is low.
The purpose of this utility model provides a kind of photoelectricity automatic detection device based on droop error, cone angle error and the compensating error (for the Geoplane of self leveling) that detect laser device for building, be equipped with different annexes, but the correlated error of other laser devices for building such as detection laser plumb aligner, laser plummet, laser level and laser level chi also.
For solving above-mentioned task, the solution that the utility model adopts is: with a high-precision automatic compensated level.Horizontal line of sight is as the horizontal reference that detects, and its sighting telescope adds neutral weakener and an industrial pick-up lens combination, forms an equivalent long-focus optical camera lens device.Introduce ccd image sensor spare, image pick-up card and microcomputer, constitute a high-precision low-angle photoelectric image measuring system.Detected laser device is placed in one by on computer control, the stepper motor driven rotary working platform, and rotary working platform can lifting, to satisfy the detection needs of the different Geoplane of outgoing laser beam height.Behind detected laser device Anping, look the accuracy requirement of detected laser device, detect the beam level error in four orientation of laser device (every 90 °), eight orientation (every 45 °) or 12 orientation (every 30 °) respectively, calculate the droop error and the cone angle error of laser device by computing machine automatically.
For the detection of self leveling Geoplane compensating error, then need on rotary working platform, to add two dimension little platform that inclines automatically, by computer control, step motor drive.After the droop error and cone angle error when detecting self leveling, in its compensation range with the little angle of inclining in self leveling Geoplane front, rear, left and right successively ground, detect self leveling Geoplane droop error and the cone angle error of this moment successively, droop error during with Anping and cone angle error relatively promptly draw the compensating error of self leveling Geoplane.
Detection for the vertical error of laser plummet apparatus and laser plummet or the accurate error of hanging down, then need on rotary working platform, to add a two reference field pentagonal prism, it is made of a high-precision pentagonal prism and two-sided parallel pedestal thereof, the horizontal reference that automatic compensated level is provided converts plumb datum to, can detection laser plumb aligner and the vertical error of laser plummet or the accurate error of hanging down.
The employed automatic compensated level of the utility model is calibrated through accurate i angle, therefore, and horizontal reference precision height of the present utility model.After computing machine obtains the digital picture of scanning laser beam by CCD and image pick-up card, adopt multiple averaging, elimination of rough difference method and sub-pix close classification to extract the center of scanning laser beam, eliminate environmental factor, the thermonoise of CCD and the influence of accidental error effectively, reduced scanning laser beam and beam level error.This device guarantees that through after demarcating accuracy of detection is better than 1 ", resolution is better than 0.5 ".The sighting telescope of automatic compensated level and an industrial pick-up lens combination, form an equivalent long-focus optical camera lens device, when guaranteeing accuracy of detection, shortened the volume of this device effectively, the physical dimension of this device (not containing computing machine and output device thereof) is about: 700mm (L) * 700mm (H) * 300mm (W).This device can be placed on the stable workbench because volume is little, and therefore, this device has vibration resistance well, is not subjected to external interference.The control and calculating automatically owing to use a computer, operating personnel only need detected laser device Anping on rotary working platform can be detected automatically, and the time of detecting a laser device is about 2 minutes, so this Device Testing efficient is very high.This device only needs operating personnel's operation, can finish detection.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural drawing of the present utility model.
The utility model is made up of a long-focus optical camera lens device (1), ccd image sensor (5), image pick-up card (6), computing machine (7), stepper motor (8) and rotary working platform (9), and wherein long-focus optical camera lens device (1) adds that by automatic compensated level (2) neutral weakener (3) and an industrial pick-up lens (4) form.The scanning collimated laser beam that detected laser device sends is focused on the ccd image sensor (5) through long-focus optical camera lens device (1), and the image of scanning laser beam enters computing machine (7) through image pick-up card (6) and handles.The testing process of Geoplane is: start the control detection software on the computing machine (7), on request relevant initial parameters of input and controlled variable (input when using for the first time uses visual detection to require to do suitably to revise later on).Detected Geoplane is placed on rotary working platform (9) goes up and Anping, open the power switch of Geoplane, Geoplane sends a branch of collimated light and begins scanning.With the selected test button of mouse, computing machine (7) is by the controlled variable of setting in advance, every 90 ° of four orientation, 45 ° of eight orientation or 30 ° 12 orientation rotary working platforms (9), and measure the beam level error in each orientation of Geoplane, calculate the droop error and the cone angle error of Geoplane then automatically.
