Description
Technical field
The utility model relates to a kind of indicator, especially relates to a kind of wire harness electrical measurement indicator.
Background technology
At present, the wire harness tester applies to automotive wire bundle factory widely.For test loop and the few test board of holder, the small-sized tester that generally adopts lower LCD of price or LED to show; And, can adopt the LCD tester for loop and the more test board of holder, also can adopt higher PC control of price and the test macro that shows.But the tester for LCD shows generally has only test function, does not but have the holder deixis.To P/N and the more test macro of holder, require the operator to concentrate by energy, therefore in allegro work, can produce visual fatigue, extremely influence work efficiency.
The utility model content
The purpose of the utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists that a kind of usable range is wide, security good, efficient is high, simple in structure, maintenance and engineering change (EC) wire harness electrical measurement easily indicator.
The purpose of the utility model can realize through following technical scheme:
A kind of wire harness electrical measurement indicator; It is characterized in that; Comprise PLC, plastic anchor clamps holder, wire harness tester and touch-screen, the plastic anchor clamps are provided with LED light and switch pin, and described PLC is connected with LED light, switch pin, wire harness tester, touch-screen respectively.
The input end of described PLC is connected with the output terminal of wire harness tester through the P/N signal plate; Described P/N signal plate is provided with four relays; The output contact of these four relays is connected with the PLC input point, and described wire harness tester is connected with four relay coils.
LED light behind described switch pin and the series resistor is connected with PLC through transit plate.
Described PLC stores the holder strobe state information under the different P/N.
Compared with prior art, the utlity model has following advantage:
1, usable range is wide: can be used as the auxiliary indication unit of the global wire harness test macro of various projects, particularly for the test macro that contains bail, the inspection that can walk abreast has greatly improved test speed.
2, security is good: indicate the position of bail to be measured or loop holder automatically, it is wrong that the operative employee is difficult for dress; Dress is staggered the time, and can point out and mistake proofing.
3, efficient is high: the multi-position action worker operates in the time of can be according to the pilot lamp information of same; Can self-sustaining to adorning wrong bail, confirming that the wrong back of dress takes out bail, do not need resetting system just can continue detection.Reduce the time of testing waste again after the maloperation.
4, simple in structure: adopt PLC, practiced thrift the space, integrated circuit board quantity also reduces a lot, the total system clear in structure is understood.
5, maintenance and engineering change (EC) are convenient: the tool wiring of bail only need be received PLC input, output change-over panel, can directly check each holder switch pin and LED performance quality with touch-screen during inspection.Also there is special button can directly check the quality of all lamps on the touch-screen.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1; A kind of wire harness electrical measurement indicator; Comprise PLC5, plastic anchor clamps, wire harness tester 4 and touch-screen 1, the plastic anchor clamps are provided with LED light 3 and switch pin 2, and described PLC5 is connected with LED light 3, switch pin 2, wire harness tester 4, touch-screen 1 respectively.
The function of PLC comprises that holder reads with holder for P/N information and induces indication; Whether plastic inserts judgement and the prompting of holder; The correct insertion state of bail is collected and the prompting of mistake proofing, behind the clear plate of EOT to the self check and the results suggest of switch pin.
The input point of PLC5 is connected to four relay output contacts of P/N signal plate, the relay on the wire harness tester 4 control P/N signal plates, and relay output drives the PLC input with 8421 code combination modes, can reach 16 P/N options.
LED light 3 on the above-mentioned holder needs serial connection 5k resistance, is connected in the output of PLC5, and external 15V power supply is as the driving power of LED.
Above-mentioned holder switch pin 2 is connected to the input end of PLC5.For loop holder, whether the switch pin inserts the judgement signal of holder as plastic; For bail holder, whether the action of switch pin is as bail correctly the judgement signal of check and extinguishing or glimmer prompting operation person to make the judgement of next step action through PLC control LED.
The state exchange plate of above-mentioned holder plastic is to be connected to wire harness tester 4 to the state whether plastic inserts holder from PLC5, as 4 pairs of bails of wire harness tester and performing check and clear plate after the self check that whether resets of switch pin.
Above-mentioned touch-screen 1 and PLC program are downloaded and mouthful are connected, and each holder has the information of P/N, with the permanent holder strobe state information under the register-stored difference P/N in the PLC, fill in or show through touch-screen.After test beginning, the holder title that plastic does not insert holder or inserts all open of back can both be presented on the screen, is convenient to unordered detection and several operator operates simultaneously.
Specific operation process is following:
Touch-screen 1 is connected to the communication port of PLC, can read and show the status signal of holder switch pin 2 among the PLC, and also may command holder LED light 3 is bright/go out, can also revise each holder " the enabling " under different P/N that stores in the PLC and select; 2 lines of holder switch pin 2 are connected to PLC 5 input ends and input common port; Holder LED light 3 is connected to the output terminal of PLC 5 and the output terminal of 15V power supply; The holder status signal of PLC 5 outputs is connected on the I/O plate of tester 4.Behind scanner scanning P/N, the selection signal of tester 4 output P/N is given PLC 5, and PLC is after obtaining P/N selection signal; Extract " enabling " selection information of each holder in the register, and drive the holder LED light 3 of P/N appointment, the operator can directly insert plastic among the holder of bright lamp according to the prompting of the LED light on the holder 3; Holder switch pin 2 is depressed the back closure at plastic; This closure signal is extinguished by programmed control LED light 3 after being received by PLC, has not inserted plastic if having among the holder of bright lamp; LED light 3 on this holder can be glimmered prompting operation person's mistake; For bail holder, after the insertion bail made switch pin 2 closed action, LED lamp 3 extinguished, and the information that the switch pin is closed is kept by PLC 5, and the switch pin information of these maintenances sends to electric pilot 4 by PLC 5, and electric pilot can be accomplished disorderly, concurrently and detect; Tester 4 is clear plate behind pass; Switch pin in the PLC 5 keeps information to discharge immediately, and still closed if wire harness takes off some switch pin 2 of back, PLC 5 can issue tester 4 to the information of closure; Tester 4 can be pointed out the bundle that do not harden clearly; The last LED light of holder 3 can be bright, and plastic does not take off or the switch pin does not reset among the prompting operation person holder, and the worker that needs repairing overhauls.
