Abstract
The utility model belongs to product detection devices, especially relating to an automatic detection device for installing position of a valve rocker. The detection device is composed of image acquisition equipment, a motion control unit and an industrial control computer (image processing unit). The image acquisition equipment is composed of an industrial camera, an image acquisition card, an optic lens and a light source, wherein the industrial camera is connected with the industrial computer via a POE interface. An execution mechanism is composed of a motion control card, an I/O card, a Siemens programmable logic controller (PLC) and the like, the motion control card receives control commands emitted by the computer, and the PLC controls a stepping motor, a light source controller and an air pressure valve to push a camera obscura to carry out shooting in a specific position. The industrial control computer is responsible for acquisition processing and motion control of camera images. Lasers are respectively emitted to the head portion and tail portion of the valve rocker to find out area of light spots to detect whether the installing position of the valve rocker. According to the utility model, the installing position of the valve rocker can be detected rapidly, accurately and automatically.
Description
Technical field
The utility model relates to a kind of automatic detection device of the valve rocker installation site based on machine vision, belongs to the product detection range.
Background technology
Valve rocker is indispensable part in the motor car engine valve actuating mechanism, it is actually a double-arm lever, be used for the power that valve actuating push rod transmits is changed direction, according to the working cycle of carrying out in each cylinder of engine and the requirement of ignition order, time opening and close the inlet and outlet door, make fresh charge (gasoline engine is that combustion mixture, diesel oil device are air) in time enter cylinder, and waste gas is in time discharged from cylinder.In the industrial processes process, unavoidable because odjective cause causes the skew of rocking arm installation site, the method for traditional contact manual detection not only loaded down with trivial details, labour intensity is big, and detection speed is slower, can not eliminate artificial measuring error.Also may cause certain damage to object surfaces in testing process, the requirement of this and the desired on-line quick detection of modern industry is not inconsistent.
The utility model content
People's fatigue, carelessness, slower deficiency of detection speed easily when overcoming manual detection, the utility model provides a kind of valve rocker installation site automatic checkout system based on machine vision, the accuracy rate of detection and speed, reduction manual detection cost can be improved in the installation site of can real-time online stability and high efficiency ground detecting valve rocker.
The technical scheme that the utility model adopts is:
The pick-up unit of valve rocker installation site is made of image capture device, motion control unit, industrial computer (graphics processing unit).
Image capture device is made up of industrial camera, image pick-up card, optical lens and light source, and industrial camera is connected with the ADVANTEK610 industrial computer by the POE interface, gives Computer Processing with the image data transmission of gathering.
Motion control unit is made up of motion control card, 7250I/O card, Siemens S7315-2DP/PN programmable logic controller (PLC), RFID communication module/west door ASM456, stepper motor etc.Motion control card is accepted the control command that computing machine sends, and sends a signal to PLC by the terminal row on the control card, and PLC control step motor, light source controller and air pressure valve events promotion camera bellows are taken pictures at assigned address and got mutually.7250 cards are used for controlling unlatching and the closure of light source.
Industrial computer is the core control section, mainly bears acquisition process and the motion control of camera image.
Light source adopts 1 bar shaped red LED lamp and eight infrared laser light sources, and it is evenly distributed on the top of lamp box.
High speed camera adopts linear array CCD camera, is fixed on the cross bar of frame, and by POE interface and industrial computer communication, adopts the Gige Data Transport Protocol.
Detecting valve rocker, characteristic such as whether put in place, whether whether virtual connection of rocking arm, rocking arm lack is installed is by beating head and the tail position at rocking arm with two laser respectively, realizing by the area of searching Blob (hot spot).
The beneficial effect of the utility model device: utilize machine vision technique to gather the image information that is contained in valve rocker on the cylinder block fast, real-time online is stablized the installation site detection that precise and high efficiency carries out valve rocker, this system also establishes automatic warning, show testing result in real time, realize the robotization that the identification of valve rocker installation site is handled.
Description of drawings
Fig. 1 is valve rocker surveyed area position view.
Fig. 2 is valve rocker installation site pick-up unit structural drawing.
Fig. 3 is the image detection process flow diagram.
In the accompanying drawing 1, A, B, C and D are four surveyed areas on the valve rocker edge.
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing to the utility model pick-up unit.

Whole testing process is shown on the man-machine interface of host computer (2) in real time, will detect data simultaneously and preserve, and traces to the source in order to carry out data.
The utility model device can be realized the robotization that the identification of valve rocker installation site is handled.
It more than is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all belongs in the scope of utility model technical scheme any simple modification, equivalent variations and modification that above embodiment does.
