Description
Technical Field
The utility model belongs to the calibrating installation field relates to auxiliary device for graduated flask examination, especially a camera fixing device for graduated flask examination.
Background
With the popularization of machine vision technology, the technology of replacing manual identification and collection of devices to be inspected by the machine vision technology is developed.
Taking the calibration technology of the measuring cylinder as an example, it is a general technology to collect the liquid level and the scale of the liquid in the measuring cylinder by using a camera. In the existing calibration process for a measuring cylinder, a guide rail is generally installed at a position beside a scale of the measuring cylinder along a longitudinal direction, a camera is installed in the guide rail through a sliding block, and an extending direction of a lens of the camera is perpendicular to the measuring cylinder. The position of the sliding block is required to be adjusted according to the corresponding height when the scales or the liquid level of the measuring cylinder are collected, and the height of a lens of the camera and the liquid level are ensured to be at the same horizontal height.
However, the above-mentioned device has a certain disadvantage in use, and because the length of the camera mounted with the lens is long and the extending direction of the camera is perpendicular to the moving direction of the guide rail, the shake generated in the moving process is aggravated to be transmitted to the lens side, and the imaging quality is further reduced. In addition, in order to ensure the working focal length and the imaging visual field of the camera, a certain working distance needs to be reserved for the camera, and the miniaturization of the instrument is not facilitated.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's is not enough, provides a rational in infrastructure, reduces the shake, shortens the camera fixing device for graduated flask examination of the interval between guide rail and the graduated flask.
The utility model adopts the technical proposal that:
the utility model provides a camera fixing device is used in graduated flask examination, includes a graduated flask that awaits measuring, and the side position relative with the scale that should wait to examine the graduated flask and make installs a guide rail along vertical, and slidable mounting has a slider, its characterized in that in this guide rail: one end of the sliding block is movably provided with a camera, one end of the sliding block, which is far away from a camera lens, is provided with a reflector, and the reflector can reflect the scales of the measuring cylinder into the lens.
Furthermore, the extending direction of the central axis of the lens of the camera is parallel to the extending direction of the measuring cylinder.
And the angle formed by the reflector and the central axis of the lens is 45 degrees.
The utility model has the advantages that:
the utility model discloses in, adjust the collection position of camera lens to the direction that parallels with guide rail extending direction, later gather the center pin position that the scale reflection of graduated flask to the camera lens through the speculum. On one hand, the extending direction of the lens is parallel to the moving direction of the guide rail, so that the shaking direction generated by starting and stopping the sliding block is coincident with the moving direction of the guide rail, and the influence of shaking on image acquisition is reduced; on the other hand, increased the interval between camera lens and the speculum, and then prolonged the camera lens and wait to gather the distance between the object, under the prerequisite of the work focus of guaranteeing the camera and the field of vision, can shorten the interval between graduated flask and the guide rail, effectively practice thrift the space, the device of being convenient for is miniaturized.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention is further illustrated by the following examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the invention.
The utility model provides a camera fixing device is used in graduated flask examination, includes a graduated flask 6 that awaits measuring, vertically installs a guide rail 2 along the side position relative with the scale that should wait to examine the graduated flask and make, and slidable mounting has a slider 3 in this guide rail, the utility model discloses an innovation lies in, the one end movable mounting of slider has a camera 5, and the one end that camera lens was kept away from to this slider is installed a reflector 7, and the reflector can be with the scale reflection of graduated flask to the camera lens in.
In this embodiment, a plug 1 is respectively installed at two ends of the guide rail, so as to prevent the sliding block from dropping out.
In this embodiment, the extending direction of the central axis of the lens of the camera is parallel to the extending direction of the measuring cylinder.
In this embodiment, an angle formed between the reflective mirror and a central axis of the lens is 45 °.
In this embodiment, a mounting seat 4 is integrally fixed to one side end of the slider, and the mounting seat can be fixed to the bottom of the camera.
The utility model discloses a working process is:
the utility model discloses during the use, the camera that will install the camera lens passes through the mount pad to be fixed at the tip of slider, and later the clear scale of can gathering in the camera eyepiece is guaranteed to the adjustment focus, later can use. When collecting, the picture can be recorded by the camera only by ensuring that the reflector and the liquid level of the measuring cylinder to be detected are at the same height.
The utility model discloses in, adjust the collection position of camera lens to the direction that parallels with guide rail extending direction, later gather the center pin position that the scale reflection of graduated flask to the camera lens through the speculum. On one hand, the extending direction of the lens is parallel to the moving direction of the guide rail, so that the shaking direction generated by starting and stopping the sliding block is coincident with the moving direction of the guide rail, and the influence of shaking on image acquisition is reduced; on the other hand, increased the interval between camera lens and the speculum, and then prolonged the camera lens and wait to gather the distance between the object, under the prerequisite of the work focus of guaranteeing the camera and the field of vision, can shorten the interval between graduated flask and the guide rail, effectively practice thrift the space, the device of being convenient for is miniaturized.
