Technical Field

The utility model belongs to cable detection device especially relates to a robot encoder detection device that breaks for the rapid judgement NACHI robot encoder cable breakpoint position.

Background

The NACHI robot is a famous brand of a famous japanese robot company. At present, the NACHI robot in a punching workshop is used for carrying punching plates among various projects, wherein 8 robot encoder cables are arranged among each project, each cable is composed of 10 thin signal wires and has a complex trend, and the cables are too long and are more in plug connectors. It is very difficult to find when the breakpoint appears in the encoder cable, because the cable overlength, and the bayonet joint is the pencil and connects, can't use the universal meter to measure the break-make. The encoder cable needs to pass through the tank chain, so that time is wasted when the elimination method is used for judging faults, even a whole set of cable and the tank chain need to be replaced to solve the faults, the required time is 4-6 hours, the production line stop time is prolonged, and the production efficiency is seriously influenced.

The technical scheme includes that the device comprises a power supply, a USB charging interface, a switch with an indicator light, a double-display voltage ammeter, an encoder cable plug connector, an indicator light with a button switch, a first wire harness plug, a second wire harness plug, a third wire harness plug and a short-circuit unit main body frame, wherein the power supply is respectively connected with the switch with the indicator light and the double-display voltage ammeter, the USB charging interface is connected with the power supply in parallel, a pin + of the 9 indicator light with the button switch is respectively connected with the encoder cable plug connector in parallel, a pin-line of the 9 indicator light with the button switch is respectively connected with the double-display voltage ammeter in parallel, a pin-line of the 9 indicator light with the button switch is also respectively connected with a pin-line of the switch with the indicator light in parallel, the pin + of the switch with the indicator light is connected with the encoder cable plug connector, the first wire harness plug, the second wire harness plug and the third wire harness plug are respectively fixedly connected with the short-circuit unit main body frame, the back of the interface of each wire harness plug is connected with the encoder plug pins of the encoder.

The power supply of the utility model is a chargeable nickel-hydrogen battery pack.

Encoder cable connector is embedded, has 12 sockets, wherein has two to be empty.

Take button switch's pilot lamp is from the recovery.

The utility model has the advantages that the structure is novel, can find out which specific line has the breakpoint in NACHI robot encoder cable fast, judge the fault location fast, reduce the intensity of labour who seeks the fault point, reduce the equipment maintenance time, when the production task is nervous, can use the method of external signal line to correspond production temporarily even, under the condition of having accomplished not changed the cable is whole, also can correspond production in the very first time, the production line stop time that has greatly reduced, the loss because of the production line stops to bring is reduced; adopt the pilot lamp of taking button switch, have self-checking function, can judge whether to be the device body problem through pressing the pilot lamp to reduce the misjudgement.
