A servo motor and an encoder are fixed by the bracket. The servo motor is in 1:1 connection with the encoder by a flexible coupling. The servo motor is electrically connected with a servo driving device by a data line. The servo driving device is provided with a position control card, is integrated with an interface of a PROFIBUS bus and is connected to a programmable controller device by the bus. The programmable controller device comprises a high-speed counter template and an analog quantity output template and is integrated with a PROFIBUS/CAN interface. The programmable controller device acquires an electric signal of the encoder by the data line and transmits the acquired and processed electric signal to an upper computer.
Description
Technical field
The utility model relates to the checkout equipment field, especially a kind of digital encoder (magneto-electric, photo-electric, PROFIBUS/CAN bus type) on-line measuring device.
Background technology
As everyone knows, along with manufacturing development, many technical matterss to be solved have appearred in development of technology.Wherein scrambler manufacturing firm how effectively just be faced with, key parameters such as the signal quality of complete detection scrambler and stability, the validity of checking procedure and method is just concerning the stability of scrambler product.
Along with development of technology, continually developing of novel coding device, and the present detection means of scrambler does not obtain corresponding raising, after particularly the scrambler of absolute value, PROFIBUS/CAN bus mode emerges, traditional detection means can't be checked, perhaps simply test, hand-kept, caused the stability of scrambler generally not high.
Existing detecting instrument adopts common electric machine to be rotated mostly, the umber of pulse of counting circuit capturing and coding device feedback, cardinal principle measuring means as just low line number encoder device, can't test to high line number, bus type, absolute value formula scrambler, and the data of gathering only are rotating speed and feedback quantity, and are just powerless for angle, voltage and data recording.The servomotor of employing is also arranged as calibration instrument, but at different scramblers, checking equipment just need be made change, it is standby to make several covers, cumbersome, and simultaneously, data recording adopts manual mode or no record.Lack comprehensive, comprehensively a detection platform and a recording means for the performance of scrambler, stability, therefore be difficult to guarantee the stability that manufactures a product.
Summary of the invention
In order to overcome the deficiency of existing digital encoder (magneto-electric, photo-electric, PROFIBUS/CAN bus type) detection means, the utility model provides a kind of on-line detecting device for digital encoder, this device is not only simple in structure, and detects the encoder type wide ranges; Not only can detect the feedback signal of digital encoder, and can accurately detect the anglec of rotation, and rotating speed requirement accurately is provided, can also detect the also detection signal situation of in it allows several rate ranges of voltage range, power respectively for the scrambler of low voltage power supply (+5V direct current).
The technical scheme that its technical matters that solves the utility model adopts is: a kind of on-line detecting device for digital encoder, be provided with support, servomotor and scrambler are fixed by support, servomotor is undertaken being connected at 1: 1 by flexible coupling and scrambler, servomotor is electrically connected with servo drive through data line, servo drive has position control card and integrated PROFIBUS bus interface, and be connected to the Programmable Logic Controller device by bus, the Programmable Logic Controller device should comprise the high-speed counter template, the analog quantity output template, integrated PROFIBUS/CAN interface, the Programmable Logic Controller device is through data line capturing and coding device electric signal, and the electric signal after the Programmable Logic Controller device will be gathered and handle flows to host computer.
The beneficial effects of the utility model are, this device is not only simple in structure, and modular combination, install the module that all need, and just can detect and need not change hardware multiple digital encoder.Carry out hardware connection and software selection according to different detection needs, install back start detection program, follow-up step has just realized robotization and information system management.
