Below to Device Testing process prescription of the present utility model:
1, warping roller 3 is placed on the roller mounting groove 5, the operation trace routine according to operator's role, is selected different user name logins, and program is provided with the role of three kinds of different operation authorities, and authority is respectively from low to high: operator, slip-stick artist, keeper.
" operator " identity is used for the general operation personnel, only can carry out basic operation to software, comprises the selection product type, and the operation trace routine is checked I/O state etc.After the automatic measuring ability operation of software, the operator only need mark to the groove of " damage " and get final product.
" slip-stick artist " identity is used for the technician, and authority has comprised all functions of " operator ", can also carry out functions such as parameter is provided with in addition, comprises adding new product model etc.Correlation parameter (standard value) according to measured object carries out the relevant parameters setting, and parameter is arranged to the product type of different measured objects, and the operator can be selected.By the detection of actual " size " and the standard value of setting are compared to draw testing result.
" keeper " identity can also be safeguarded systemic-functions such as user ciphers except that the authority that comprises " slip-stick artist ".
2, we are with " operator " identity logging program.After selecting product type, click: " detection " button, program begins automatic measuring ability.
3, detect picture as shown in Figure 5.
Because the restriction of CCD camera 2 resolution, once can only detect 3 grooves, when camera 2 is moved to detecting position by servomotor 23 drivings, the signal that puts in place that camera 2 receives from the PLC control system carries out picture-taking automatically, and three grooves is wherein measured, the data of measuring comprise groove width, gash depth, ditch groove radius, and separation.First three measurement data respectively has 3 groups, and separation is 2 groups, because have only two separation between 3 grooves.After having detected real data, these data and " standard value " that " slip-stick artist " sets are compared, when the actual detected data fit is set tolerance, show, represent this size conforms request for utilization of this groove with green background; When the actual detected data exceed the setting tolerance, all show with red background, represent that this size does not meet request for utilization.
If all measurement data all meet the requirements, promptly be green entirely, computing machine 7 can send " qualified " signal to the PLC control system, 23 operations of PLC control system control servomotor, CCD camera 2 is navigated to next detection position, after putting in place, start the detection that CCD camera 2 carries out again.If one and more than one red parameter appearance are arranged, promptly there is one or more actual measurement data undesirable, then CCD camera 2 can stop at this position, at this moment, the operator need mark to this undesirable groove, press reset button afterwards, make CCD camera 2 move to next detection position and proceed to detect.
Above process constantly repeats, and all grooves of a certain angle are all measured to detect and finished on a cylinder, and the manual swing roller of operating personnel is measured testing once more to another angle.A cylinder will have the position of four angles measured at least.
From above testing process as can be seen, software section of the present utility model comprises two parts, the control program of control servomotor 23 location among trace routine on the computing machine 7 and the PLC.The program flow diagram of two parts program cooperation operation as shown in Figure 6.
