Abstract
The utility model specially relates to an automatic testing apparatus for a wire harnesse, which belongs to a product detection field. The automatic testing apparatus mainly comprises a wire harness adapter, a PLC control unit, a switch amount input module, a switch amount output module and a real time on-line monitor unit. The real time on-line monitor unit comprises a man-machine monitor interface and an alarm. One end of a detected wire harness passes through a wire harness adapter to be connected with the switch amount output module a PLC, and the other end passes through the wire harness adapter to be connected with the switch amount input module of the PLC. The PLC control unit controls the high level signal emit by the switch amount output module to pass through the wire harness to be acquired by the switch amount input module, and the PLC control unit completes wire harness model discrimination and connection case analysis through software. According to the automatic testing apparatus for a wire harness, the structure is simple, operation is convenient, and rapid and accurate automatic detection to the wire harness is achieved.
Description
Technical field
The utility model relates to a kind of automatic testing equipment of wire harness, belongs to the product detection range.
Background technology
After wire harness referred to contact element terminal crimping that the multiple conducting wires cable forms via the copper material punching out, the outside is the assembly of a kind of connecting circuit of forming of plastic compression insulator (as plastics, rubber etc.) or added metal housing again.In current each electric field, little of small household appliances, mobile phone, instrument, in automobile, aircraft or army's industry equipment, all need to use wire harness greatly.Increase along with device upgrade makes functions of the equipments, the wire harness that uses in the equipment is day by day complicated.Safe and reliable in order to guarantee wire harness, must carry out conduction detection to wire harness.Generally, the union line of wire harness connector is many, detect relatively also more complicated, and present many wire harness connectors all is by manual detection, and detection efficiency is relatively slow, and has increased labour's cost, should not produce in enormous quantities.
The utility model content
For omission, false retrieval and the efficient that solves the manual detection existence waits problem slowly, the utility model provides a kind of automatic testing equipment of wire harness, for the inside connection situation that detects wire harness has accurately and rapidly been created condition.
The technical solution of the utility model is as follows:
Automatic testing equipment mainly is made of wire harness breakout box, PLC control module, switching input module, switching value output module and real time and on line monitoring unit.The real time and on line monitoring unit is made up of man-machine monitoring interface and alarm.
Tested wire harness one end links to each other with the switching value output module of PLC behind the wire harness breakout box, and the other end links to each other with the switching input module of PLC behind the wire harness breakout box.
By the switching input module collection, the PLC control module is finished the wire harness model by software and is differentiated and the analysis that is connected situation behind the high level signal process wire harness that PLC control module gauge tap amount output module sends.
During test, PLC gauge tap amount output module adds a high level signal successively at the wire harness input end, gathers the level signal of wire harness output terminal by switching input module; Wire harness input endpoint and corresponding wire harness exit point conducting when the signal of gathering is high level; When the signal of gathering is opened a way during for low level; If low when high during level, then loose contact.
The utility model proving installation is simple in structure, and is easy to operate, can carry out fast wire harness, accurately detect.
Description of drawings Fig. 1 is a kind of structural drawing of automatic testing equipment of wire harness;
Fig. 2 is the process flow diagram of the automatic test of wire harness.
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing to the utility model proving installation.
As signal input part, each end points is designated as I with an end of wire harness
i(i=1,2,3 ..., n); The signal output terminal of the other end, each end points is designated as O
i(i=1,2,3 ..., m), n and m may not wait.In PLC, preset the input/output relation tables of data of corresponding wire harness correspondence when qualified according to the wire harness model.
System brings into operation, and the user selects " the wire harness model of detection " or differentiates model automatically with a qualified wire harness test back by man-machine interface, after selecting to finish, and the trace routine of PLC software transfer correspondence.PLC software control output and load module are carried out data output and are gathered, and finish data analysis.
Concrete testing process: during test, PLC software control switch amount output module i end points of wire harness input end (i=1,2,3 ..., n) add a high level signal successively, gather wire harness output terminal O by switching input module
j(j=1,2,3 ..., level signal m); I input endpoint Ii of wire harness and corresponding wire harness exit point O when the signal of gathering is high level
iConducting; Open a way during for low level; If low when high during level, then loose contact.
PLC is shown to result's output on the man-machine interface after analyzing data (namely comparing with the input/output relation tables of data of presetting) after the circulation.When undesired connection occurring, system can give the alarm and show the terminal number of wrong.
The utility model proving installation can carry out fast wire harness, accurately detect.
It more than is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all belongs in the scope of utility model technical scheme any simple modification, equivalent variations and modification that above embodiment does.
