Abstract
The invention relates to an encoder which is also called a speed and displacement sensor. The invention specifically relates to a novel special encoder for servo motors. A servo motor using the encoder can be automatically controlled in real time. The encoder comprises a cable, an encoder body, a movable grating, a fixed grating, a shell and a circuit board. The encoder is characterized in that the encoder further comprises a cable socket and a fifteen-core single-row terminal; the cable socket is arranged on the circuit board; the shell is provided with a socket slot matched with the cable socket; and the fifteen-core single-row terminal is arranged in the end part of a cable. The encoder of the invention is simple and reasonable in structure; by adopting a contact pin type terminal output mode, the encoder is space-saving, convenient for assembly and low in assembly cost; accidents of signal loss or abnormal work of equipment at a client use end are not caused; and the encoder has strong anti-interference capability.
Description
Technical field
The present invention relates to a kind of scrambler, claim again speed and displacement transducer, a kind of Novel servomotor encoder special, is used the servomotor of this scrambler can realize in real time control automatically specifically.
Background technology
Encoder for servo motor is mounted in a kind of sensor that is used for measuring position of magnetic pole and servomotor corner and rotating speed on servomotor, this basic function of encoded servo device is the same with conventional coders, increment of rotation scrambler is exported pulse when rotating, by counting equipment, calculate its position, when scrambler is motionless or have a power failure, rely on the memory internal of counting equipment to remember position, in addition, encoded servo device also has with the different place of conventional coders, that is exactly servomotor most is synchronous motor, in the time of synchronous motor startup, need to know the position of magnetic pole of rotor, can start servomotor by high-torque like this, need to join in addition the current location that several signals carry out detection rotor like this, such as incremental, just there are signals such as UVW.
The domestic encoded servo device manufacturer that do not produce a few years ago, multi-servomotor factory all selects external Heidenhain and Duo Mo river encoded servo device greatly, external encoded servo device is expensive, and specifications and models, volume size are single, causes that domestic servomotor cost is high, motor type is few; The domestic country that was subject in recent years supports that He Ge great research institute develops, introduction of foreign technology, present domestic encoded servo device technology maturation, price has more abroad reduced a lot, domestic Ge great servomotor manufacturer also selects domestic encoded servo device, 1 year needs sales volume hundreds of thousands platform of dimensions of market mostly.
Original old-fashioned scrambler adopts the artificial bonding wire way of output, 1., the Traditional Man bonding wire way of output there is a lot of shortcoming and defect, be in particular in:, easily occur failure welding, cause rosin joint, the undesirable element such as soldered, cause client to use for a long time lossing signal or equipment not to work.2., work efficiency is low in the circuit board by manually wire being connect one by one for original mode of connection, cost of labor is high, operator be not easy operation, often cause bad accident.3., because servomotor working environment is influential for anti-electrostatic discharging interference etc., so old-fashioned artificial welding is due to contacting with pcb board that etween the lines contact, line have, can cause for a long time anti-interference bad.
Summary of the invention
The object of the invention is to provide a kind of simple and reasonable, adopt the mode of contact pin type terminal output, save space, easy to assembly, save assembly cost, can not cause the accidents such as signal appears losing in client's use side or equipment work is undesired, the encoder special for servo motor that antijamming capability is strong.
The object of the present invention is achieved like this, this scrambler comprises cable, encoder main body, moving grating, determines grating, shell, circuit board, it is characterized in that: it also comprises a cable socket and a single terminal of 15 core, described cable socket is arranged on circuit board, on shell, with a socket slotted eye matching with cable socket, the described single terminal of 15 core is arranged on the end of cable.
The present invention has the following advantages and good effect:
1, adopt the output of contact pin type terminal to substitute original old-fashioned artificial bonding wire way of output, artificial welding is possibility failure welding first, cause rosin joint, the undesirable element such as soldered, cause client to use for a long time lossing signal or equipment not to work, and adopt contact pin type terminal soldering, and only need to terminal soldering is good, need not consider cable color, my company of the terminal other end adopts machine intelligence crimping, and client's use side there will not be and loses signal or the accident such as equipment work is undesired like this.
2, adopt the output of contact pin type terminal easy operating person to operate, minimizing is bad accident because operator causes, client's use, because the single contact pin of the contact pin type that we just have, so outlet end line look arranges successively, be easy to client and observe, and adopt contact pin type client easily plug in the middle of use procedure.
3, because servomotor working environment is influential for anti-electrostatic discharging interference etc., so old-fashioned artificial welding is due to contacting with pcb board that etween the lines contact, line have, can cause for a long time anti-interference bad, and it is anti-interference to adopt the output of contact pin type terminal to get rid of this respect, improve Liao Wo company encoded servo device strong interference immunity.
4, servomotor the application of the invention scrambler can be realized in real time and automatically controlling, and mechanical quantity is transformed into digital transfer to control system.
5, coder structure advantages of simple of the present invention, saving space, easy to assembly, greatly saves assembly cost, also facilitate and save simultaneously the assembly cost of use producer, save time and the complicacy of Installation and Debugging process, increase work efficiency, can be widely used in Industry Control.
Accompanying drawing explanation
Fig. 1 is encoder special for servo motor one-piece construction schematic diagram of the present invention.
Fig. 2 is that the single terminal of the present invention's 15 core is plugged on the structural representation on cable socket.
Embodiment
Shown in accompanying drawing 1: this scrambler comprises the single terminal 2 of cable socket 1,15 core, cable 3, encoder main body 4, moving grating 5, determines grating 6, shell 7, circuit board 8, described encoder main body 4 is arranged in shell 7, moving grating 5, determine grating 6 and circuit board 8 is arranged on encoder main body 4, on described shell 7, with a single terminal 2 of socket slotted eye 9, ten five core matching with cable socket 1, be arranged on the end of cable 3.
Described moving grating 5 is connected on main shaft encoder basement, on circuit board 8, is provided with electric elements.
Every pin in described scrambler cable socket 1 is exported a road signal, substituting original wire transmits, user side has the single terminal 2 of 15 core as matched plug, can directly be inserted on cable socket 1, by subsequent conditioning circuit, process like this, can finally obtain needed signal, can play conserve space, reduce resetting difficulty, the effect of convenient for maintaining.
