Stream electricity.Additionally, it will be appreciated by persons skilled in the art that along with wireless power such as electromagnetism is humorous
The development of formula of shaking wireless power technology and application, it is also possible to dispense energising track 158 and change
For providing wireless power to jig platform 157, such as, wireless power is set in jig platform 157
Receiving coil receives wireless power.
Secondary positioner 159 is such as arranged on the outside of transmission track 151, and is specially setting
Between transmission track 151 and energising track 158.Herein, include can for secondary positioner 159
Elevating movement (namely the direction being perpendicular to paper along Fig. 2 moves up and down, it is such as driven by cylinder
Dynamic) the push rod of stopping means such as liftable motion；And preferably, detecting position and pan feeding/discharging
Position is provided with secondary positioner 159.When LED display module to be measured being detected by sensor
Arrive detecting position (the such as position of jig platform 157 shown in Fig. 2) or pan feeding/discharging position is (such as
The position at rightmost side slide 153 place in Fig. 2) time, cylinder (not shown in Fig. 2) promotes liftable
The stopping means of motion does ascending motion, thus stops that slide 153 temporarily moves on, and passes simultaneously
Send the motor stalls of power set 155；Such then the location of slide 153 can be realized, protect
Demonstrate,prove its accuracy every time arriving detecting position.
Hold above-mentioned, it is to be understood that the LED display module detection of the present embodiment and calibration equipment
10 also can be configured with the such as PC (not shown) of the host computer for installing correction software, its
The LED display module arriving detecting position is entered by middle correction software for controlling image collecting device 13
Row image acquisition, picks out faulty and does not meets the LED display module that bright chroma requires, and
Complete LED point calibration coefficient to be uploaded to control card and write the operation of LED display module.This
Outward, LED display module detection and calibration equipment 10 also can configure independent PLC (in figure
Not shown), with control whole equipment run the relevant operating of board 15, stop, the work such as location.
Furthermore, in the inner space 100 shown in Fig. 1, it is preferably also provided with thermostat (figure does not shows
Go out) keep equipment 10 internal temperature constant, such as equipment 10 internal temperature is between positive and negative 2 degree
Constant.
Further it will be understood that scalable shade 17 can also be fixed on jig platform 157
On, realize scalable shade 17 by arranging corresponding power set in jig platform 157
Stretching motion the most repeatedly.
Below in conjunction with Fig. 1 to Fig. 4 the LED display module of this utility model embodiment detected and
The running of calibration equipment 10 is described in detail:
A () LED display module is put into: LED display module put into from pan feeding/discharging opening, LED
Display module can be placed in above the jig platform 157 being positioned at pan feeding/discharging position, is now placed in pan feeding
The secondary positioner 159 of/discharging position stops the slide 153 arriving pan feeding/discharging position and it needs to behaviour
Make personnel to be just released from by an ACK button slide 153 stopping and can moving on；
B () LED display module detects: LED display module is transported to along transmission track 151
During detecting position, each slide 153 that transmission track 151 is installed stops walking, and (namely streamline is temporary
Stop work and make) and the slide 153 of secondary positioner 159 stop arrival detecting position, above detecting position
Scalable shade 17 stretches downwards and covers one local dark room conditions of LED display module formation,
Ensure that whole LED display module is not disturbed by ambient light when image detects；Correction software is to figure
As harvester 13 (including camera and spectrogrph) sends image capture instruction to being in detecting position
The image light that LED display module sends carries out reflecting institute's shape via reflecting mirror 111,113 and 115
Become exit image light be acquired, and collection result is supplied to correction software carry out process point
Analysis draws the correction coefficient of each LED point in LED display module and judges that LED shows
Module whether fault and do not meet bright chroma requirement；Afterwards, correction software sends to PLC
Image detects completed instruction, and scalable shade 17 upwards shrinks, and is positioned at the secondary of detecting position
Positioner 159 releases the stop of the slide 153 being pointed to detecting position, and LED display module flows
To next station, and above a LED display module next arrives at detecting position, so circulates；
C LED display module is uploaded and write to () data: LED display module from detecting position continue to
After be sent to pan feeding/discharging position during complete correction coefficient upload and write LED show mould
The operation of block, in other words, transmission track 151 also has between position at detecting position and pan feeding/discharging
Correction coefficient is uploaded and writes position；
D () LED display module is taken out: the LED display module finishing all operations finally can flow
To pan feeding/discharging position, be now placed in pan feeding/discharging position secondary positioner 159 stop arrive into
The slide 153 of material/discharging position.If LED display module is no problem, then can by operator from
Pan feeding/discharging position directly by LED lamp panel module take out, if LED display module is faulty or
Not meeting the requirement of bright chroma disparity range, equipment can send the alarm operation of light and sound
Personnel.
In sum, the LED display module of this utility model embodiment detects and calibration equipment: i)
Detection and the correction data that can complete LED display module upload preservation function, such as at 10 seconds
Inside completing detection and the collection of correction required image of LED display module, wherein LED shows mould
Block detection includes common fault, the such as problem such as bad point, bright spot, can also detect that not simultaneously
Meet the LED display module of bright chroma area requirement and reject；Ii) multiple batches of LED can be completed
Display module such as LED lamp panel calibration function, due to the adopting of spectrogrph in image collecting device 13
With, it is highly suitable for multiple batches of LED display module needs to be corrected to a bright chroma set
The situation of desired value, completed the flow process of all corrections, bag before LED display module flows out simultaneously
Include the uploading of correction coefficient, write LED display module and be saved in data base.As can be seen here,
This utility model can meet client for LED display module fully-automated synthesis and the demand of correction,
It is greatly improved production efficiency；In the long run, the automatic of LED display production can be greatly improved
