Existing high dynamic shooting, improves sweep speed and precision, and CMOS cameras are used using industrial camera 4, and the advantage of CMOS is unusual
Power saving is because cmos circuit only just has the consumption of electricity almost without static state electric quantity consumption when circuit is connected.This is allowed for
It is exactly to process fast-changing image that the power consumption of CMOS only has the subject matter that 1/3 of common CCD or so, CMOS is faced
When, because curent change is excessively frequently overheated.Dark current suppress great question just less, if suppressing bad with regard to ten partial volumes
Easily there is miscellaneous point.It is the amplifier of electronic signal by charge conversion that each pixel of cmos sensor has one, therefore, CMOS
Sensor can carry out signal amplification in each pixel basis.Any invalid transmission operation can be saved in this way,
So only need a small amount of energy ezpenditure to can be carried out rapid data scan, while noise also decreases.Preferably, can use
The industrial vision system of the series of Cognex IN-SIGHE 5000.The serial vision systems of In-Sight 5000 are current world markets
Upper unique a industrial intelligent camera that technical grade profile can be provided.Illustrated referring to Fig. 1, in order to improve running precision and
The reliability of motion, it is preferable that the electronic slide unit 1 is ball bearing screw type straight line slide unit.The motor of electronic slide unit 1 uses servo
Motor or stepper motor, such motor ensure that electronic slide unit running precision is high, stroke ± 10mm, stepping accuracy：12-15μ
m；Reseting precision：18-20μm.Running precision is greatly improved, and improves detection efficiency.Electronic slide unit can select the production of SMC companies
Model be MXW25-300B electronic slide unit.Secret room 3 is made up of no-reflection material, meanwhile, spraying possesses extinction in secret room 3
Functional paint layer, light-absorption layer is black material, and using acoustical cotton or glass fibre cotton, the light that favourable light emitting diode sends is close
Room 3 absorbs, and improves the scan image quality of industrial camera 4.
Accurate in place in order to ensure electronic slide unit operation, automobile instrument printed board assembly automatic checkout equipment also includes stroke
Travel switch 5 is provided with switch 5, secret room 3, travel switch 5 is electrically connected with the motor of electronic slide unit 1.So, when electronic slide unit
1 in secret room 3 to running to up to specified location, and the front end crash travel switch 5 of support frame 2, the contact action of travel switch 5 disconnects control
Circuit processed, controls the motor automatic stop operating of electronic slide unit 1, while locked support frame 2, the motor of electronic slide unit 1 is brushless
Direct current generator, it is ensured that electronic slide unit 1 can accurately and reliably run in place, the need for meeting the shooting of industrial camera 4.
Illustrated referring to Fig. 1, influence the definition of IMAQ when details in a play not acted out on stage, but told through dialogues is imaged due to industrial camera, therefore, industrial phase
A certain distance is controlled between machine and printed board assembly, it is preferable that the camera lens face center of industrial camera 4 to printing to be detected
The vertical range of the upper surface of board component 6 is 28cm-32cm.So ensure that all light emitting diode groups places in printed board
The need for scope is gathered, IMAQ definition is in turn ensure that.
Illustrated referring to Fig. 1, in order to ensure printed board assembly accurate positioning, support frame 2 includes crossbearer 2-1 and two sets of vertical frame 2-
2, crossbearer 2-1 are arranged on the sliding block upper surface of electronic slide unit 1, and the two ends of crossbearer 2-1 are respectively provided with a set of vertical frame 2-2, and two sets are erected
The upper end of frame 2-2 is separately installed with the locating dowel 2-3 that can position printed board assembly 6.So, printed board assembly 6 can be fixed on fixed
On the post 2-3 of position, wherein, single locating dowel 2-3 is fixed on the vertical beam 2-2 of rear end, arrange that arranged side by side two are fixed on the vertical beam of front end
Position post 2-3, industrial camera 4 is with the benchmark of locating dowel 2-3 acquisition ranges, as long as the scanned collections of so locating dowel 2-3, then quilt
Whether the bright defect of light emitting diode group on the printed board assembly that locating dowel 2-3 is surrounded also is scanned.
The course of work
When printed board assembly 6 to be detected is reached needs the operation of ostensibly detection, printed board assembly 6 to be detected is consolidated
It is scheduled on the support column 2-3 of support frame 2, then, according to the stroke of electronic slide unit 1 set in advance, controls electronic slide unit 1 to drive
Printed board assembly 6 is moved along a straight line in secret room 3, and board component to be printed 6 is reached in secret room 3, and the sliding block of electronic slide unit 1 reaches default
Distance, or the impact stroke of support frame 2 switch 5, control the motor automatic stop of electronic slide unit 1, and the motor of electronic slide unit 1 is nothing
Brushless motor, meanwhile, opening will detect the light emitting diode of the packet on printed board assembly 6, every group of number of light emitting diode
Amount can be 5 or 7.Start the lighted region on the camera collection printed board assembly 6 of industrial camera 4, the inner side of secret room 3
Face scribbles light-absorption layer, collects high quality graphic, carries out light images collection according to default technological requirement one by one, by what is gathered
Image is compared with the standard picture in industrial camera or control system, judges whether every group of light emitting diode has the defect not worked,
And then determine a need for processing or carrying out next step operation.Automobile instrument field is applied to, is that follow-up automobile instrument operation is carried
For reliable guarantee, the production process quality and improve product quality of automobile instrument are improve.
