The soft or hard knot that product in the utility model can combine for PCB (printed circuit board) and FPC (flexible circuit board)
Circuit board is closed, in above-described embodiment is double-station equipment to laser-measured height mechanism is penetrated, if product amounts to 12 steel disc points, also
It is to amount to 24 test points.Such as detecting beat is 6s, that is to say, that needs to drive linear speed of the gauge head to be exceedingly fast by servo motor
Spend inswept all measuring points, it is necessary to all acquire altitude information in moving process.Speed in the industry has been selected to meet requirements above
Most fast Medium PLC is spent, Keyence LK series laser distance measuring sensor of arranging in pairs or groups, the scan period, fully meeting made up to 50K/s
Use demand.
It is the X/Y plane servo motion system that a set of lead screw and synchronous belt form to the core component for penetrating laser-measured height mechanism
System, laser sensor is integrated on this system, is quickly scanned to the product measuring point on fixture, and product and fixture are solid when measurement
It is fixed motionless.
In the utility model to penetrating laser-measured height mechanism there are two core point, first is that in order to guarantee upper lower sensor simultaneously
Get to the same test point of product, it is necessary to assure the center position degree of upper lower sensor；Second is that improving detection efficiency, production section is improved
It claps.
The purpose of sensor centering is to guarantee that laser point can test same position up and down, and the data only acquired exist
Spatially Z-direction is conllinear, this data is only authentic data.Even if product itself is tilted on fixture, as long as laser point pair
In it is good, generated deviation be it is extremely small, this deviation is much larger than the thickness of weight missing detection.
Guarantee the centering of Z axis, practical exactly the direction laser sensor X/Y position degree will be got well up and down.Wherein Y direction
Centering can carry out by adjusting the part of mounting surface, and difficulty is the centering adjustment of X-axis, because X-axis is quick movement side
To how to guarantee during fast moving that its measuring point does not generate deviation is the key that the utility model.
In view of the above-mentioned problems, the utility model has selected synchronous belt train as X-axis transmission mechanism, it is synchronous with transmission effect
The features such as rate is high, precision is good, flexible high, the demand suitable for the utility model.By the way that the power of upper and lower laser sensor is divided
It is not connected to the homodromous both sides of synchronous belt, realization moves synchronously.
Since synchronous belt has certain ductility, the extension of belt is not to laser sensor when in order to guarantee to read movement fastly
The influence that centering generates, the form that the utility model uses electrical compensation eliminate error.Synchronous drive force motor we select
The servo motor of external feedback control, encoder that the position feedback of servo motor does not use its original-pack, but pass through outside
The grating scale (scale grating and grating reading head) of installation carrys out feedback position signal, and laser sensor respectively corresponds one up and down
Grating scale, accordingly even when probe location generates deviation up and down, taking position a little is in some absolute position of grating scale forever.
By way of not stopping in servo operation and taking number of test points evidence, production efficiency can be improved.In order to save production
Bat faster, in above-described embodiment has added one group of high component of survey, and the additional high component of survey is worked at the same time with the fixed high component of survey.
Since two adjacent steel sheet spacing of each product Y direction are different, in order to make the compatible more products of measuring head, add
The gauge head up and down for surveying high component can drive the movement for doing Y direction by a spindle motor respectively.
Two sets are surveyed high component power simultaneously from the servo motor of side, on the one hand each Laser Measuring can be guaranteed by doing so
Moving synchronously for examination head, on the other hand can save manufacturing cost.
As can be seen from the above technical solutions, the utility model has the following beneficial effects:
It is fast to detect speed, is got ready relative to the pause of conventional measurement height, the utility model can be fast moved and be taken a little；
Detection accuracy is high, can reach 0.013mm to the precision for penetrating laser sensor in the utility model；
Electrical external feedback control eliminates error for the form for the electrical compensation that sensor takes a position to take；
Multiaxial motion drives two groups of high components of survey by a servo motor, being capable of energy saving and cost lowering；
Versatility, mechanism are all applicable under the test condition that product is excessively thin, measuring point benchmark can not be fixed.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new
