First scale is usually in non-homogeneous arrangement.
The scale image further includes identifying scale correspondingly with the meter body, so that subsequent assembling process
In will not obscure.Preferably, also label is formed with first identifier, the first identifier and mark scale one in the meter body
One is corresponding.In practical operation, it can be marked the product exclusive number of the pointer instrument as the mark scale and first
Know, is printed upon on the meter body and dial 101 respectively.Certainly, other any to can be used for the meter body and scale
Both disks 101 accurately identify, and the technological means avoided confusion can be practiced.
Particularly, the pointer instrument can be mechanical sphygomanometers, and the meter body further includes inflatable ball, bellows
And gauge outfit etc., details are not described herein with the progress of work for specific structure.The dial 101 is installed in the gauge outfit;It is described
Dial 101 is arranged rounded and its center and offers mounting hole 101c to install the pointer, i.e., the described pointer
It is connected on the machine core by the mounting hole 101c.Certainly, the dial 101 also samples such as settable fan-shaped, rectangle
Formula;The hub switch side of pointer one end that i.e. pointer is connected with the machine core may also be arranged on the side of the dial 101
Side.
Join shown in Fig. 2, the present invention goes back while providing a kind of manufacturing device to prepare aforementioned pointer instrument, including mark
Quasi- source 201, job platform 202, camera system 203, print system 204 and control system 205.
Wherein, the standard source 201 is to export set detection signal to the meter body of the pointer instrument;Institute
Image of the camera system 203 to acquire the meter body is stated, and corresponding image transmitting to control system 205 is subjected to intelligence
It can identify, determine the shift position of pointer, according to the shift position of the pointer, design obtains described the control system 205
Scale image.The camera system 203 includes industrial camera and corresponding light source;The print system 204 mainly includes industry
Flat-panel printer, preferably high-resolution color ink-jet printer, to realize the precise Printing of the scale image.The printing
System 204 is also equipped with printing jig, and the printing jig can be used to realize the fixation of at least two dials to be printed, this reality
It applies in example, the printing jig can be used for realizing the installation positioning of 100 dials to be printed.
The manufacturing device further includes marking machine 206, and the marking machine 206 is formed to mark in the meter body
First identifier, the first identifier are identical as the mark scale on the dial 101 or in being arranged in a one-to-one correspondence.The operation
Platform 202 includes shooting station and mark station, and the shooting station corresponds to the camera lens of industrial camera, and the mark station is corresponding
The head of marking machine 206.The control system 205 is also used to control the meter body and carries out station on job platform 202
Switching.
Join shown in Fig. 3, the present invention also provides a kind of manufacturing methods of aforementioned pointer instrument, specifically include that
Standard source 201 is provided, the standard source 201 is controlled and exports set detection signal to meter body, record the instrument
The shift position of the pointer of table main body;
According to the shift position of the pointer, scale image is designed;
Printing obtains the dial 101 corresponding to the meter body;
The dial 101 is assembled in corresponding meter body, pointer instrument is obtained.
The standard source 201 preferably successively exports at least two different detection signals to meter body, records respectively
The pointer corresponds to the shift position of different detection signals.It also, is so that the design of subsequent scale image is more accurate, at least
Two detection signal one correspond to the maximum range of the meter body;There are also the dead-center positions for corresponding to the pointer
Detection signal, that is, determine the pointer standard source 201 output signal be " 0 " when shift position.The movement
The determination of position specifically includes the image by meter body described in 203 shooting, collecting of camera system, and by described image
It is transmitted to control system 205 and carries out intelligent recognition, and then determine the shift position of the pointer.
The detection signal that the standard source 201 exports can be set according to range of the pointer instrument etc. point, and according to
Sequence from low to high successively determines that the pointer corresponds to the shift position of each detection signal.Change what standard source 201 exported
, need to be after the pointer complete stability of the meter body when detecting signal, then acquire image;Suppression gently tunks described in shaking
Meter body after its pointer is stablized, then acquires image.
For mechanical sphygomanometers, the standard source 201 is set as Standard Gases potential source, such as: the control system 205 is controlled
It makes the Standard Gases potential source and successively exports 6 detection signals (0,60,120,180,240 to the meter body of mechanical sphygomanometers
And 300mmHg);The pointer generates corresponding deflection, and the shooting under automatic light source effect of aforementioned industrial camera obtains the finger
The image that needle deflects every time, then shooting image is transmitted to control system 205, the control system 205 is according to image series intelligence
It can identify the shift position for determining pointer, design generates corresponding scale image.Ground can be infered, pass through increase in practical operation
The number of the detection signal carries out the design accuracy that duplicate measurements is conducive to improve the scale image, and scene needs
Production efficiency is balanced with the progress of product quality precision aspect to be considered.
In the design process of the scale image, the first scale is determined by the way that the shift position of the pointer is corresponding, then press
The region between adjacent first scale is divided along the direction of rotation of the pointer according to established rule, obtains the second scale.
Specifically, the region adjacent first scale can be divided equally, presses down or by interpolation method i.e. according to set function call
To the second scale of corresponding region position.To be assembled convenient for the later period, the scale image further include with the meter body one by one
Corresponding mark scale;Similarly, the manufacturing method further include in the meter body label form first identifier, described the
One mark is corresponded with mark scale.Specifically, the manufacturing method further includes controlling the meter body from shooting platform
It is transferred to mark platform, then controls marking machine 206 and is printed in the meter body and obtain first identifier;The meter body is also
It can be transferred to shooting platform from mark platform, the printing of the first identifier can be carried out in advance.Certainly, according to actual product need
It asks, the scale image also may include other patterns such as product information, company logo etc..
To improve production efficiency, the printing jig that the print system 204 is arranged can fix several quarters to be printed simultaneously
Scale 101.The manufacturing method further includes being fixed on several blank discs on the printing jig, then pass through the print system
204 are printed upon the corresponding scale image of several meter bodies on different blank discs respectively.
In conclusion scale image of the pointer instrument of the present invention by Photographing On-line and printing dial 101, so that institute
It is corresponding with pointer actual deflection position to state dial 101.Manufacturing device of the present invention and manufacturing method can be according to meter bodies
The shift position design of pointer prints corresponding dial 101, and it is unavoidable in manufacture process to eliminate the components such as machine core
Generated all kinds of deviations, the pointer instrument no longer needs to capable calibration after the assembly is completed, and measurement accuracy is high, effectively reduces mistake
Difference.Also, produced on-site efficiency can also be improved, manufacturing cost is reduced, is easy to implement the Reduced Design and product optimization of structure.
