Description
Technical field
The utility model relates to core image acquisition instrument field, specifically a kind of core image acquisition instrument of energy auto-focusing.
Background technology
In geological prospecting process, for understanding subterranean strata character, core-drilling is needed to carry out detailed research as sample.In recent years, along with the development of computer sample of high-resolution image, treatment technology is ripe, core is scanned into image and goes forward side by side row relax, form digitized core scan image, just comparatively intactly can preserve the raw information of core, and be convenient to retrieve very much, check, share.Core image image capture instrument technology all comparative maturity at home and abroad, defines ripe product.But existing product mostly makes to focus by hand, focusing precision is inadequate, inefficient operation.
Utility model content
The purpose of this utility model is for prior art Problems existing, provides a kind of core image acquisition instrument of energy auto-focusing merit.
Above-mentioned purpose is realized by following proposal:
A core image acquisition instrument for energy auto-focusing, it is characterized in that, described core image acquisition instrument comprises pedestal, XYZ tri-axle workbench, ultrasonic range finder sensor and camera; Described XYZ tri-axle workbench is arranged on pedestal; Described camera is fixed on the Z axis moving component of XYZ tri-axle workbench by connector, and vertically downward, described ultrasonic range finder sensor is arranged on connector and ultrasound emission direction vertically downward to the camera lens of camera; The bottom casing of described pedestal is placed with sample stage, motion controller and stepper motor driver is provided with in the bottom casing of described pedestal, described motion controller is connected to stepper motor driver by cable, described stepper motor driver be connected to by cable be installed on XYZ tri-axle workbench stepping motor on; The signal output part of described ultrasonic range finder sensor is connected to the signal input part of motion controller.
The beneficial effects of the utility model: the utility model, while scanning, is constantly measured the distance of sample to camera lens, and regulated at any time, make to remain in scanning process and focus accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, the core image acquisition instrument of energy auto-focusing of the present utility model comprises pedestal 10, XYZ tri-axle workbench 1, ultrasonic range finder sensor 5 and camera 6.XYZ tri-axle workbench 1 is arranged on pedestal 10; Camera 6 is fixed on the Z axis moving component 3 of XYZ tri-axle workbench 2 by connector 4, and vertically downward, ultrasonic range finder sensor 5 is arranged on connector 4 and ultrasound emission direction vertically downward to the camera lens of camera 6; The bottom casing of pedestal 10 is placed with sample 7, in the bottom casing of pedestal 10, is provided with motion controller 9 and stepper motor driver 8.Motion controller 9 is connected to stepper motor driver 8 by cable, stepper motor driver 8 be connected to by cable be installed on XYZ tri-axle workbench 1 stepping motor 2 on; The signal output part of ultrasonic range finder sensor 5 is connected to the signal input part of motion controller 9.
During use, ultrasonic range finder sensor 5 launches ultrasonic wave, and ultrasonic wave is reflected to form echo on sample 6 surface, is again received by ultrasonic range finder sensor 5.By calculating the time difference launching and receive echo, being multiplied by the velocity of sound again divided by 2, just obtaining the distance l` of samples to sensor termination.These distance l` data pass to motion controller 9 by voltage, electric current or RS485 mode, and motion controller 9 reads l`, deduct the difference in height of ultrasonic range finder sensor 5 termination to camera end, as the actual range l of camera end to sample.And and the focusing of systemic presupposition from l
0contrast, if l>l
0, then motion controller 9 sends pwm signal to stepper motor driver 8, and stepper motor driver 8 drives the motor 2 on XYZ tri-axle workbench 1, drives Z axis moving component 3 to move downward, otherwise then moves upward.Until l and l
0difference be less than certain little constant Δ l, then think that system completes auto-focusing, can scanning work be carried out.
