Abstract
The invention provides an engine two-dimensional code identification error proofing method. The engine two-dimensional code identification error proofing method comprises steps that, automatic model identification is carried out, whether models are consistent is determined, if yes, measuring equipment detection data are transmitted to a PLC, whether the data are consistent is determined, if yes, identification information is transmitted to an identification controller, whether data verification is correct is determined, if yes, an identification system starts. The engine two-dimensional code identification error proofing method can be in matching with an engine production line, so recorded product quality information can be correctly marked on parts, and thereby product quality control is convenient.
Description
Technical field
The present invention relates to a kind of engine Quick Response Code mark error-preventing method.
Background technology
In recent years, international automobile manufacturing industry is especially in the production run of motor car engine, and American-European countries even specifies to require to set up special quality traceability system to motor car engine with governments and laws form with professional regulation, mandatory quality standard system respectively.In the past few years, China has become automobile production and consumption big country, becomes one of leading industry pulling China's economic to increase fast.Under the market structure of globalization, Domestic Automotive Industry has started to set up relevant quality tracing standards system, and starts in production line, adopt corresponding laser two-dimensional code mark traceability system to ensure for production quality control and consumer's use safety.
Planar bar code technology can record a large amount of data messages in the effective scope of unit, there is information capacity amount large, operation and maintenance cost is low, the advantage that error correcting capability is strong and can directly carry out on part beat carve feature, this technology has the advantage of its uniqueness in the manufacture process of engine, is the trend of future development.’
Engine body group is primarily of part compositions such as cylinder block, crankcase, cylinder jacket, cylinder head and head gaskets.At present, in the production line of automobile, each key components and parts needs unique identification mark, for the identification of the tracking traceability system of production quality control and consumer's use safety.By information such as the quality of the Part No. of Quick Response Code record part, production batch, product type code and measurement.Afterwards by the identification to Quick Response Code, the relevant information of these parts can be determined.
Summary of the invention
Goal of the invention: the mark error-preventing method that the invention provides a kind of car engine Quick Response Code.
Technical scheme: engine Quick Response Code mark error-preventing method, comprises the following steps:
Carry out model automatically to identify, judge that whether model is consistent, as inconsistent then equipment alarm;
Be transferred to PLC as consistent then measuring equipment detects data, and judge that whether data are correct, as inconsistent then equipment alarm;
As consistent then identification information is transferred to mark controller, and judge that whether data check is correct, as incorrect then equipment alarm;
As correctly then started tag system, after described tag system receives the instruction of PLC, required information is printed on part with the form of Quick Response Code.
In identification procedure, as arbitrary link failure, then according to visible code, manual input coding.
Described information of identification code comprises: product designation, product, model, supplier's area code, time, date and series number.
The Quick Response Code area of described mark is 15mm*60mm.
Beneficial effect: the present invention can carry out supporting with engine line, beats the product quality information of record accurately and is engraved on part, be convenient to production quality control.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present invention
Embodiment:
By embodiment, the present invention is further described below:
Engine body group is primarily of part compositions such as cylinder block, crankcase, cylinder jacket, cylinder head and head gaskets.These parts are from after machining production line is reached the standard grade, can along with production line automatic transmission, measurement result (point level number etc. as crankshaft hole) is sent to PLC by measuring system simultaneously, controller is according to steering logic, the model production batch of product and the result of measurement are sent to the controller of tag system by RS232 data line according to certain form, in order to the correctness of check data transmission in the process of data transmission, after receiving end receives data, data are fed back again a to transmitting terminal, whether the controller of transmitting terminal compares the data sent with accepting consistent, if consistent, provide and send successful signal, otherwise provide and send failed signal, simultaneity factor prompt messages sends mistake.
Therefore require that system works as parts through mark or identification checking station, system is first automatic is fixed on desirable position by parts, required information is printed with the fixed position of the form of Quick Response Code at part after then tag system receives the instruction of PLC.If whole process completes smoothly, then green indicating lamp is had to indicate, if identify or identify or verify the failure of arbitrary link, red led then will be had to report to the police, simultaneously operator can see this coding interface by display screen, carries out manual intervention-according to visible code, manual input coding.
The part rolled off the production line is sent to assembly line, is provided with two-dimension code recognition device at the station of reaching the standard grade of assembly line, for reading the information that part stores in Quick Response Code.Data after reading are divided into according to function: the quality information code (the axle journal classification code as the classification code of connecting rod, the classification code in cylinder crankshaft hole and bent axle) of part, the type code of part, the production batch code etc. of part, these codes, when assembly line assembles, will carry out corresponding quality control, mistake proofing false detection and product traceability control etc. according to type.These information can be delivered in information carrier by a PLC part for assembly line, and another part is delivered in server, with this engine for information about together be stored in database, so that later inquiry and reviewing.The quality informations such as the classification of part directly write in carrier, and the assembling pallet with engine flow into next station, and in follow-up assembly station, mistake proofing control is carried out in the requirement according to assembling.
Claims (4)
