Description
Technical field
The invention belongs to LED production technical fields, more particularly to a kind of side for LED light splitting machines correction and repetition measurement
Method.
Background technology
The later stage is encapsulated in LED, testing classification is carried out to the semi-finished product of batch production using light splitting machine, mainly pass through light splitting
Machine tests luminosity, coloration and electrical parameter, then by the material Screening Treatment union of identical luminosity, coloration and electrical parameter section
In to together.Per a batch LED semi-finished product before needing to be divided, the necessary advanced rower of light splitting machine is fixed, just can guarantee spectrophotometric test
Accuracy.Light splitting machine will first get out a LED standard lamp bead before carrying out proving operation, and LED standard lamp bead has phase
It should be divided the standard value of parameter and specified spectrophotometric test operating current, standard lamp should utilize the standard mechanism for meeting professional standard
It generates.LED standard lamp bead type must be consistent with tested light splitting LED type, and rated operational current is tested with tested LED
Electric current is identical, and parameters are consistent with professional standard when to ensure test, and error is smaller.
However, to pass through multiple working procedure since LED is processed as LED semi-finished product to be divided from raw material, the production cycle is longer,
It cannot be remained exactly the same in the state of different time sections equipment, environment, employee, be influenced may result in by these external factors
The semi-finished product to be sorted that final production comes out have different, so if the standard lamp chosen does not have representativeness, it is every
The parameters of the parameter value not instead of batch of material are in marginal position with respect to median, then each when can cause to produce in batches
The test error of item parameter is larger；Since light splitting board itself has smaller error when testing parameters, if when long
Between if operation, since the board long period is in the state that runs at high speed, the error for testing the function module of parameters can be slow
Slowly become larger, the material that the later stage produces when long working is caused to have certain difference with the material produced early period.
