Abstract

The utility model relates to a coder special for a servo motor, wherein real-time automatic control can be realized through the servo motor with the coder; the coder comprises a cable, a coder body, a movable grating, a fixed grating, a shell and a circuit board and is characterized by further comprising 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 at the end part of a cable. By adopting the contact pin type terminal output manner, the coder special for the servo motor disclosed by the utility model is simple and rational in structure, space-saving, convenient for assembly, low in assembly cost and strong in anti-interference capability; and accidents that signals are discarded at a client use end or equipment works abnormally and the like cannot be caused.

Description

A kind of encoder special for servo motor

Technical field

The utility model relates to a kind of encoder, claims again speed and displacement transducer, and a kind of Novel servomotor encoder special uses the servomotor of this encoder can realize in real time automatically control specifically.

Background technology

Encoder for servo motor is mounted in a kind of transducer that is used for measuring position of magnetic pole and servomotor corner and rotating speed on the servomotor, this basic function of encoded servo device is the same with conventional coders, the increment of rotation encoder is the output pulse when rotating, calculate its position by counting equipment, motionless or when having a power failure when encoder, rely on the memory internal of counting equipment to remember the position, in addition, the encoded servo device also has with the different place of conventional coders, that is exactly servomotor most is synchronous machine, need to know the position of magnetic pole of rotor in the time of synchronous motor startup, can start servomotor by high-torque like this, need to join in addition the current location that several signals come detection rotor like this, such as incremental the signals such as UVW just be arranged.

The domestic encoded servo device manufacturer that do not produce a few years ago, large multi-servomotor factory all selects external Heidenhain and Duo Mo river encoded servo device, 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 subjected in recent years supports to develop with each large research institute, introduction of foreign technology, present domestic encoded servo device technology maturation, price has more abroad reduced a lot, domestic each large servomotor manufacturer also selects domestic encoded servo device, 1 year needs sales volume of dimensions of market hundreds of thousands platform mostly.

Original old-fashioned encoder 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, is in particular in:, failure welding easily occurs, cause the undesirable elements such as rosin joint, weldering company, cause the client to use for a long time lossing signal or equipment not to work.2., original mode of connection is low by manually wire being connected on one by one on the wiring board operating efficiency, cost of labor is high, the operator is not easy operation, often causes bad accident.3., because the servomotor operational environment is influential for anti-electrostatic discharging interference etc., so old-fashioned artificial welding is because contacting with pcb board of having of etween the lines contact, line can cause anti-interference bad for a long time. ?

Summary of the invention

The purpose of this utility model is to provide a kind of simple and reasonable, adopt the mode of contact pin type terminal output, save the space, easy to assembly, save assembly cost, can not cause client's use side accident, the encoder special for servo motor that antijamming capability is strong such as signal or equipment work is undesired to occur losing.

The purpose of this utility model is to realize like this, this encoder comprises cable, encoder main body, moving grating, decides grating, shell, circuit board, it is characterized in that: it also comprises a cable socket and the single terminal of 15 cores, described cable socket is arranged on the circuit board, with a socket slotted eye that is complementary with cable socket, the single terminal of described 15 cores is arranged on the end of cable on the shell.

The utlity model has following advantage 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 the possibility failure welding at first, cause the undesirable elements such as rosin joint, weldering company, cause the client to use for a long time lossing signal or equipment not to work, and adopt the contact pin type terminal soldering, and only need to be good terminal soldering, need not consider the cable color, my company of the terminal other end adopts the machine intelligence crimping, and the accidents such as signal or equipment work is undesired can not appear losing in client's use side like this.

2, adopt the output of contact pin type terminal the easy operating person to operate, minimizing is bad accident because the 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 the client and observe, and adopt contact pin type client easily plug in the middle of use procedure.

3, because the servomotor operational environment is influential for anti-electrostatic discharging interference etc., so old-fashioned artificial welding is owing 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, has improved my company's encoded servo device strong interference immunity.

4, servomotor the application of the invention encoder can be realized in real time automatically control, and mechanical quantity is transformed into digital transfer to control system.

5, the utility model coder structure advantages of simple, saving space are easy to assembly, greatly save assembly cost, also make things convenient for and save simultaneously the assembly cost of use producer, save time and the complexity of Installation and Debugging process, increase work efficiency, can be widely used in Industry Control.

Description of drawings

Fig. 1 is the utility model encoder special for servo motor overall structure schematic diagram.

Fig. 2 is that the single terminal of the utility model 15 cores is plugged on the structural representation on the cable socket.

Embodiment

Shown in accompanying drawing 1: this encoder comprises cable socket 1, the single terminal 2 of 15 cores, cable 3, encoder main body 4, moving grating 5, decides grating 6, shell 7, circuit board 8, described encoder main body 4 is arranged in the shell 7, moving grating 5, decide grating 6 and circuit board 8 is arranged on the encoder main body 4, be arranged on the end of cable 3 on the described shell 7 with a single terminal 2 of socket slotted eye 9, ten five cores that is complementary with cable socket 1.

Described moving grating 5 is connected on the main shaft encoder basement, is provided with electric elements on the circuit board 8.

Every pin in the described encoder cable socket 1 is exported one road signal, substituting original wire transmits, user side has the single terminal of 15 cores 2 as matched plug, can directly be inserted on the cable socket 1, process by subsequent conditioning circuit like this, can finally obtain needed signal, can play conserve space, reduce resetting difficulty, the effect of convenient for maintaining.
