The semi-automatic test frock of instrument
Technical field
The present invention relates to a kind of semi-automatic test frock of instrument, for being tested electrical measuring instrument and being conveyed.
Background technology
Electrical measuring instrument is the meter and instrument for measuring, recording and measuring various electrical quantities.Electrical measuring instrument
It is divided into ammeter, voltmeter, ohmmeter, power meter, power-factor meter, frequency meter, phase meter, synchronizing indication by measurement function
Universal meter of device, electric energy meter and multiple use etc..
These electrical measuring instruments need to carry out performance detection after the completion of production, ensure that it can be with normal work, generally
Detection method be by being manually connected to the binding post of commissioning device on instrument one by one, turned on the power again after connection and voltage
Electric current, so as to be tested with commissioning device instrument.But such test mode every time will be by manually by many wiring
Connected with instrument, complex procedures, operating efficiency is not high, while worker also has the risk got an electric shock;And detect completion also
The artificial classification for carrying out certified products and defective work is needed, manual sort often occurs the situation of misclassification, defective work occurs
It is mingled in certified products.
The content of the invention
The purpose of the present invention is to be to overcome above-mentioned deficiency, there is provided a kind of simplified process, improves operating efficiency, reduces worker
Electric shock risk, and automaticity is high, the semi-automatic test frock for the instrument that can classify automatically.

There is pusher cylinder, and conveyer belt is provided with defective work material road in the relative side with pusher cylinder, and defective work material road is with passing
Send band to be connected and set obliquely, instrument can be shifted onto during pusher cylinder operation in defective work material road and carry out defective work and return
Receive, and the end of conveyer belt is connected with finished product material road;
Simultaneously the gravity sensor in intermediate station, manipulator, rotary cylinder, sensor, pusher cylinder with PLC control system phase
Even, the Automatic Conveying carried out by PLC control system.
The invention has the advantages that:
Instrument is put into by the semi-automatic test frock of this instrument above instrument locating rack along stopper slot, promotes push rod by instrument
Shift onto in fixed plate, and the corresponding binding post in the instrument back side is propped up with thimble, such commissioning device just be able to will be believed by wire
Number it is linked into instrument, be subsequently passed corresponding Current Voltage value and accessory power supply etc. just can debug to instrument.So just can
Simplify worker's process, improve operating efficiency, reduce worker's electric shock risk;It is automatic by setting manipulator to detect the instrument completed
Grab and conveyed on conveyer belt, certified products are transferred directly in certified products Turnover Box, and defective work will be by pusher cylinder
Shift defective work material road onto, eventually enter into defective work Turnover Box.It can so be examined with being automatically performed the detection of instrument and classification
It is convenient to survey, and efficiency is higher, and the situation that classification can be avoided to malfunction.
