Specific implementation mode
Presently filed embodiment is described in detail below in conjunction with accompanying drawings and embodiments, thereby how the application is applied
Technological means solves technical problem and reaches the realization process of technical effect to fully understand and implement.
The first embodiment of scan-type strip stocking thickness profile measuring instrument：
As shown in Figure 1, scan-type strip stocking thickness profile measuring instrument includes：It is arranged and is pricked above and below material in strip
First gauge head 1 and the second gauge head 2, the first gauge head 1 and the second gauge head 2 are just corresponding, i.e. the central axis plane of the two and the thickness for pricking material
Perpendicular intersection be same point, can ensure the accuracy of measurement result in this way.Strip pricks material and is generally sheet, though there is thickness,
But thickness is very little relative to length and width, it is said herein prick material up and down both sides refer to pricking material it is horizontal positioned when it is upper,
Lower both sides only indicate the relative position relation of three.
When measurement, the first gauge head 1 and the second gauge head 2 are moved reciprocatingly with identical speed to the same direction, are always ensured that
The perpendicular intersection for the central axis plane that two gauge heads prick material thickness with strip is same point.The preferred straight line of movement locus, from bundle material
The scanning of this side coordinates the automatic running pricked in material producing line and prick material to the other side of bundle material, to complete to prick the thickness of each point of material
The measurement of degree.First gauge head 1 and the second gauge head 2 are arranged on gauge head track, and in the respective track of the driving lower edge of driving mechanism
It is mobile.It will be apparent that projection of two gauge head tracks 4 on the central axis plane for pricking material thickness is completely superposed, just can guarantee in this way
The sensing point of two gauge heads is corresponding when measurement, and measurement data just can be accurate.Driving mechanism 3 is connect with gauge head, for giving
The movement of gauge head provides power.
The measuring principle of the application is as shown in figure 3, the first gauge head 1 and the second gauge head 2 are measured respectively respectively apart from measured object 5
Surface distance L1 and L2, subtract L1 and L2 with the distance between the first gauge head 1 and the second gauge head 2 L, you can obtain measured object
The thickness x of 5 (namely strip bundle materials).It can measure several or even many times when scanning measurement, can therefrom select thickness
Maximum value, minimum value；Also all summations for measuring thickness divided by pendulous frequency can be used to acquire average value；It can also be according to these measurements
Value simulates the profile for pricking material surface using emulation tool.
First gauge head 1 and the second gauge head 2 select linear array laser displacement sensor gauge head.Gauge head is electric with control unit respectively
Connection, control unit are used to receive the metrical information for calculating L1 and L2, and according to consolidating between these information and each pair of gauge head
The bundle material thickness that set a distance calculates L1, L2 and each puts；Further according to the maximum value, most of the bundle material THICKNESS CALCULATION thickness of each point
Small value and average value.The technology of laser ranging there has been in every profession and trade to be widely applied, and the prior art is belonged to, no longer superfluous here
