Abstract
The utility model discloses an automatic screw installation check machine which comprises a screw feeder, an electric torque screwdriver drive and a microprocessor unit, wherein the electric torque screwdriver drive is connected with the microprocessor unit through a first optoelectronic isolator and a first waveform shaper; the screw feeder is connected with the microprocessor unit through a second optoelectronic isolator and a second waveform shaper, and the microprocessor unit simultaneously receives feed signals from the screw feeder and rotation signals from the electric torque screwdriver drive to judge whether the screws are installed in place. The automatic screw installation check machine provided by the utility model can detect the poor items such as lack of driven screws, wrong driving and inadequate torque to ensure the product quality by using the microprocessor unit and utilizing the signals of the external torque screwdriver drive and the screw feeder.
Description
Technical field
The utility model relates to a kind of automatic checking device, relates in particular to the screw installation self-verifying machine that need play several screws at a station.
Background technology
Screw in the complete machine production run is concluded in the operation, adopts the artificial mode of confirming in the past always.Because the uncertainty of manual work, when particularly in a station, needing to beat several different screw, the generation that screw no marking, wrong situation of beating are difficult to avoid.After yet Bu Pin Group is upright, in inferior engineering, find bad very difficult.Therefore,, guarantee product percent of pass, be necessary to provide the screw robot scaler, guarantee product quality, conclude the automatic affirmation of operation, substitute manually-operated, improve reliability in order to realize screw for guaranteeing product quality.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of screw the self-verifying machine is installed, and can detect that screw is beaten less, wrongly beaten, moment do not conclude the bad item of operation, assurance product quality to these screws.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to provide a kind of screw installation self-verifying machine, comprise screw supply machine, wherein, described screw is installed automatic monitor and is also comprised electrokinetic moment spiral shell cutter driver and microprocessor unit, and described electrokinetic moment spiral shell cutter driver links to each other with microprocessor unit with first waveform shaper by first photoisolator; Whether described screw supply machine links to each other with microprocessor unit with second waveform shaper by second photoisolator, judge screw from the rotating signal of the supply signal of screw supply machine and electrokinetic moment spiral shell cutter driver and be in place thereby described microprocessor unit receives simultaneously.
The utility model contrast prior art has following beneficial effect: the screw that the utility model provides is installed the self-verifying machine, by using microprocessor unit, utilize outside moment spiral shell cutter and screw to supply with the signal of machine, can detect that screw is beaten less, wrong beaten, moment do not conclude the bad item of operation, assurance product quality to these screws.
Description of drawings
Fig. 1 is that screw of the present utility model is installed self-verifying machine structural representation;
Fig. 2 installs self-verifying, counter works schematic flow sheet for the utility model screw.
Among the figure:
1 electrokinetic moment spiral shell cutter driver, 2 screws are supplied with machine 3 first photoisolators
4 second photoisolators, 5 first waveform shapers, 6 second waveform shapers
7 microprocessor units, 8 charactron drivers, 9 double figures sign indicating number display tubes
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is that screw of the present utility model is installed self-verifying machine structural representation.
The screw that the utility model provides is installed the self-verifying machine, comprise screw supply machine 2, wherein, described screw is installed automatic monitor and is also comprised electrokinetic moment spiral shell cutter driver 1 and microprocessor unit 7(Micro Control Unit), described electrokinetic moment spiral shell cutter driver 1 links to each other with MCU 7 with first waveform shaper 5 by first photoisolator 3; Described screw is supplied with machine 2 and is linked to each other with MCU 7 with second waveform shaper 6 by second photoisolator 4, and described MCU 7 receives simultaneously from the supply signal of screw supply machine 2 and the rotating signal of electrokinetic moment spiral shell cutter driver 1 and judges whether screw is in place.
Above-mentioned screw is installed the self-verifying machine, and wherein, first photoisolator 3 and second photoisolator 4 are selected TLP-280 IC for use; First waveform shaper 5 and second waveform shaper 6 are selected CD40106 IC for use; Microprocessor unit 7 is selected PIC16F877 for use.
MCU 7 can link to each other with double figures sign indicating number display tube 9 by the charactron driver, shows the screw number of successfully installing, and charactron driver 8 is selected M74HC595 IC for use.
The screw that the utility model provides is installed the self-verifying machine and is detected the signal of getting screw from screw supply machine 2, detect screw from moment spiral shell cutter and conclude the signal whether the back moment that puts in place arrives, judge whether screw gets mistake, conclude moment and whether arrive by this device then, if problem reports to the police immediately, if screw number all correct then that set subtracts one automatically.Circulation and so forth is up to the whole installations of screw.Flow to next station as all not finishing parts, then report to the police at once.
Fig. 2 installs self-verifying, counter works schematic flow sheet for the utility model screw.
Please continue referring to Fig. 2, from block diagram start, portion's product that needs are concluded are positioned on the tool, and program begins to carry out, and wait for the signal of screw supply machine 2.By the time obtain the screw signal and produce, pass to second waveform shaper 6 after isolating by second photoisolator 4 and carry out wave shaping, pass to microprocessor unit 7 again and handle.Then, wait for electrokinetic moment spiral shell cutter driver 1 moment arriving signal.After torque signals produces, carry out wave shaping, pass to microprocessor unit 7 again and handle by passing to first waveform shaper 5 after 3 isolation of first photoisolator.Then, wait for that the operator on the electrokinetic moment spiral shell cutter driver 1 discharges the screwdriver switching signal among Fig. 2.After the screwdriver switch discharges, electrokinetic moment spiral shell cutter driver 1 among Fig. 2 produces signal, and pass to microprocessor unit 7 among Fig. 2 via first photoisolator 3 among Fig. 2 and first waveform shaper 5, the screw of setting is installed number and is subtracted one automatically, judges then whether the screw number is zero.If be zero, operation is finished, and comes back to block diagram start.If non-zero is then got back to wait and obtained the screw signal diagram, so move in circles, up to the end of job.Detect the spiral shell cutter reverse signal of the electrokinetic moment spiral shell cutter driver 1 among Fig. 2 as the microprocessor unit in the middle graph 27, the microprocessor unit 7 among Fig. 2 waits for that operators confirm whether to take off screw.In this way, the screw of demonstration is installed number and is added one automatically, and gets back to wait and obtain the screw signal diagram.As not, directly get back to wait and obtain the screw signal diagram.As the centre: a kind of screw has not been beaten, and just lays not obtain the moment arriving signal after a kind of screw or a screw are concluded, and just obtains next screw or operation and does not finish, and portion's product are taken from tool or the like, and this device will be reported to the police with different error codes.
Though the utility model discloses as above with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
