The measuring method of a kind of PCB cutter of the present invention and device thereof are compared with the middle control machine of prior art, have following advantage:
First, on load mode, because its feeding clip mechanism is made up of first mechanical arm 37, second mechanical arm 35 and mechanical arm 31, and this first mechanical arm 37, second mechanical arm 35 and mechanical arm 31 work that can cooperatively interact, make this measuring instrument can utilize mechanical arm 31 clamping test bars, realize not having the artificial feeding process that gets involved, thereby improved automation degree of equipment greatly;
The second, on measuring accuracy,, make that its operating platform 2 thermal expansivity are little owing to adopt marble material to make operating platform 2, can effectively reduce the influence of external environment to equipment precision; Owing to adopt gene scholar measuring head 41, DRB rectilinear motion controller 44, control panel 6 cooperatings, make this measuring instrument measuring error can be controlled at ± 0.0005mm in, and can show the various states of current bar in real time, and then the guiding operation personnel judge and operate;
The 3rd, on the charge mode,, make this measuring instrument to sort out processing to different measuring result's bar owing to adopt a plurality of charging trays 5 to hold bar, can also prevent effectively that bar from being polluted, and can avoid collision mutually between the bar;
The 4th, on measuring speed,, make that the operation of each several part can be relatively independent because feeding clip mechanism 3 and testing agency 4 are separated fully, this just provides assurance for accelerating detection speed; This measuring instrument can according to how many automatic translational speeds of adjusting mechanical arm of measurement point, this can not only measure (after tested with preferable speed with regard to guaranteeing this measuring instrument, the Measuring Time that this measuring instrument has shortened 0.5-3.05 second than the middle inspection machine of prior art), can also guarantee that first screw mandrel 38, second screw mandrel 34 do not need always to move under limiting velocity, thereby prolong the serviceable life of first screw mandrel 38, second screw mandrel 34.
In addition, because control desk of the present invention also utilizes PC industrial computer and motion control board card control system to carry out data analysis and demonstration, this had both simplified the setup and operational operation, and was simple and clear again, and the handled easily personnel grasp the Data Dynamic of measuring bar in real time.
The foregoing description only is used for further specifying the measuring method and the device thereof of a kind of PCB cutter of the present invention; but the present invention is not limited to embodiment; every foundation technical spirit of the present invention all falls in the protection domain of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
