Abstract
The utility model discloses a kind of CCD leak-checking apparatus, including CCD camera, shadow-free light source, mounting bracket, all-in-one, guide rod, bracket.Mounting bracket is placed on the table, and CCD camera and shadow-free light source can be adjusted axially position on guide rod, and guide rod is fixed in mounting bracket, and detected industrial goods are positioned over light source away from CCD camera side.The device is used to detect vane pump internal leakage.After finished product vane pump is completed, by motor driving blade pump work, under physical condition, the CCD leak-checking apparatus will be detected to the internal leakage of vane pump drain tap, and the product of design requirement is not met according to monitoring result rejecting internal leakage.The device can be fast and accurately judged whether qualified make of project monitored for being detected industrial goods rapidly in seconds, eliminated manually timing Detection task, improved efficiency, reduce intensity of workers.
Description
Technical field
Components field and Hydraulic Field are the utility model is related to, more particularly to a kind of CCD detection means.
Background technology
CCD, English full name：Charge-coupled Device, Chinese full name：Charge coupled cell.It is properly termed as CCD
Imaging sensor, also it is image controller.CCD is a kind of semiconductor devices, optical image can be converted into electric signal. CCD
The small photoactive substance of upper implantation is referred to as pixel（Pixel）.The pixel count included on one piece of CCD is more, its picture provided point
Resolution is also higher.CCD to act like film the same, but it is that optical signal is converted into charge signal.There are many rows on CCD
Neat photodiode is arranged, light can be sensed, and converts optical signals into electric signal, through external sampling amplification and analog-to-digital conversion
Circuit conversion is into data image signal.In hydraulic pump internal leakage detection, the liquid of leakage is collected by manual time-keeping mostly, it is right
For batch production detection, work is repeated and workload is very big, and very big pressure is brought to operating personnel, and inefficient.
Therefore, how to mitigate intensity of workers, improve detection efficiency and correctness, be that those skilled in the art are urgently to be resolved hurrily
Problem.
Utility model content
Primary and foremost purpose of the present utility model is to provide a kind of CCD leak-checking apparatus, to reduce intensity of workers, simultaneously
Improve detection efficiency.
To achieve the above object, the utility model provides a kind of CCD leak-checking apparatus, including CCD camera 1, bracket 2, peace
Fill support 3, shadow-free light source 4, all-in-one 5 and guide rod 6.The camera is fixed on camera and is fixed on the bracket 2, described
Bracket 2 is connected on the guide rod 6, and the guide rod 6 is fixed in the mounting bracket 3, and the shadow-free light source 4 passes through screw thread
It is connected on the guide rod 6, and between the CCD camera 1 and detected fluid column 10；The detected fluid column 10, one
Body machine 5 is respectively positioned on the 7 of workbench, the shadow-free light source is away from the side of CCD camera 1.The shadow-free light source 4 is with being detected
The distance between fluid column 10 is adjustable.
Fluid column 10 is detected always in vertical plane, the camera lens cross section of CCD camera 1 also is located in perpendicular.
The side of workbench 7 sets hydraulic power unit 8.
The front in the shadow-free light source 4 is provided with retracting device 9, receiving port, shadow-free light source 4, the CCD of the retracting device 9
The center of the camera lens three of camera 1 is point-blank.
The shadow-free light source 4 and spacing 10cm~25cm of CCD camera 1.
The all-in-one 5 leaks hunting software needed for program comprising CCD camera, to analyze in the photographic image of CCD camera 1
The width L of fluid column 10 is detected, and judges to be detected the leakage rate size of fluid column 12 with database information contrast, with voice mode
Testing result is reported to operating personnel.
To reduce installation cost, detected fluid column using being manually put in place by this detection means, due to using soft
Part automatic capturing is detected fluid column position, it is not necessary to ensures to be detected the accuracy of product riding position.
In summary, compared with hand inspection is detected project, the utility model holds the work largely to consume one's energy
Carry on a shoulder pole, there is advantages below：
1st, it is detected post internal leakage size due to being absorbed by CCD camera, it is not necessary to which manual measurement internal leakage is big
It is small, greatly reduce the labor intensity of staff.
2nd, the leak-checking apparatus can realize comparative analysis by software, it is not necessary to by manually testing, several seconds
Interior can draws measurement range, improves detection efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model CCD leak-checking apparatus；
Fig. 2 test mode schematic diagrames；
Fig. 3 is detected the test schematic diagram of fluid column 10.
Embodiment
It is below in conjunction with the accompanying drawings and specific real to make those skilled in the art more fully understand the technical solution of the utility model
Applying mode, the utility model is described in further detail, but following embodiments are not intended to limit the utility model.
As shown in figure 1, the utility model detection means includes CCD camera 1, shadow-free light source 4, mounting bracket 3, all-in-one
5th, guide rod 6, bracket 2, the bracket 2 are arranged on the guide rod 6, and the guide rod 6 is fixed in the mounting bracket 3, institute
State shadow-free light source 4 to be threadedly attached on the guide rod 6, rotatable threaded adjusting, the shadow-free light source 4 is located at the CCD
Between camera 1 and detected fluid column 10, the detected fluid column 10, all-in-one 5 are respectively positioned on workbench 7, shadow-free light source 4
With spacing 10cm~25cm of CCD camera 1.
After hydraulic power unit 8 places, operating personnel start hydraulic power unit 8, and hydraulic power unit 8 sprays fluid column, fluid column operation rail
Mark is that parabola flows into retracting device 9, as shown in Figure 2；
It is detected fluid column and image as shown in Figure 3 is presented under CCD camera, L is the width for being detected fluid column 12, and CCD shines
The photographic image of camera 1 is transferred among software, and software is by after detecting electric signal and being analyzed, with database information pair
Than electric signal will be obtained a result by algorithm, be reported automatically " OK " or " NG " by the audio system of all-in-one after comparison.
Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
