Abstract

The invention provides an automobile body tracing system for an automobile production workshop, comprising code carriers, read/write heads, display screens, a PLC, and a computer. One or more code carriers are installed on a production conveying mechanism, and one code carrier corresponds to one automobile body position on the production conveying mechanism. The first read/write head is installed on a start station corresponding to the production conveying mechanism, and the other read/write heads are installed on operation stations needing a read/write head. The start station and the operation stations are each equipped with one display screen, and the display screens correspond to the read/write heads on the stations in a one-to-one mode. The PLC is used as a controller. The computer pre-stores the information of all models. The PLC is connected with the computer. The PLC is connected with the read/write heads on the stations and the corresponding display screens. The read/write heads and the code carriers communicate based on radio frequency. According to the invention, the positions of automobile bodies can be known in real time, and part information needed for operation on the stations can be displayed.

Description

Automobile production workshop vehicle body traceability system

Technical field

The present invention relates to the conveyor control field of auto production line, especially a kind of automobile production workshop vehicle body traceability system adopting read/write head recognition system.

Background technology

Along with the development of market economy and perfect, the management work of enterprise is also managed by original extensive style and is improved to the management of refinement type, the sales volume of functional department's major concern enterprise product and output in the past, but along with Market competition aggravation, improving constantly of the automation level of enterprises, the continuous reinforcement cooperated between each production link, makes functional department more and more be concerned about the material supply, equipment state, logistics distribution etc. of each production link.

Vehicle body was when producing in the past, producers are according to the card carried with car, the part needing assembling is determined according to information above, experienced staff is relied on to carry out producing, dispatching in the past, ability, the energy of people are limited, be easy to cause the means of production such as device product to pile up at the scene, production scene is chaotic, has a strong impact on production efficiency.

Summary of the invention

For the deficiencies in the prior art, the invention provides a kind of automobile production workshop vehicle body traceability system, add read/write head recognition system, based on vehicle information write data carrier, utilize the read/write head be arranged in workshop to read vehicle information, the position of vehicle body can be understood in real time and show the parts information of each station manipulation needs.The technical solution used in the present invention is:

A kind of automobile production workshop vehicle body traceability system, comprising: comprise data carrier, read/write head, display screen, PLC and computer;

One or more data carrier is arranged on produces on conveying mechanism, and a data carrier corresponds to the vehicle body position produced on conveying mechanism;

First in read/write head is arranged on the initial station corresponding with producing conveying mechanism, and all the other are arranged on each needs on the operation position of read/write head;

Initial station and operation position all arrange display screen; Read/write head one_to_one corresponding on display screen and this station;

PLC, as controller, has pre-deposited each vehicle information in computer;

PLC is connected with computer; PLC connects read/write head on each station and corresponding display screen; Read/write head and data carrier pass through twireless radio-frequency communication.

Further, data carrier is for install at equal intervals.

Further, data carrier adopts RFID label tag.

Further, PLC is connected by fieldbus with read/write head.

The invention has the advantages that:

1) safe and reliable, the input read/write head recognition system of vehicle information completes automatically, avoids the error rate of artificial input vehicle information.

2) Information Monitoring amount is large: data carrier can carry the character of tens, and every character has different implications according to initial definition, and namely systematic collection can be mapped to corresponding vehicle body to this character.

3) practical flexibly: read/write head reads data carrier information, can be used alone, also can form a system with relevant identification equipment and realize robotization identification as a kind of means of identification, can also link up with other opertaing devices and realize automatic management.

Embodiment

Below in conjunction with concrete drawings and Examples, the invention will be further described.

The present invention proposes a kind of automobile production workshop vehicle body traceability system, add read/write head recognition system wherein, write by read/write head or read vehicle information, producing the collection of real time phase reinforcement to information, the particular location of vehicle body can be specified thus integrate material supply.

This automobile production workshop vehicle body traceability system comprises data carrier 1, read/write head 2, display screen 3, PLC4 and computer 5; Each data carrier 1 and read/write head 2 constitute read/write head recognition system.

As shown in Figure 1, one or more data carrier 1 is arranged on produces on conveying mechanism, and data carrier 1 is moved together along with producing conveying mechanism; Data carrier 1 is preferably installed at equal intervals, and a data carrier 1 corresponds to the vehicle body position produced on conveying mechanism; Data carrier 1 can adopt RFID label tag, can carry the character of tens; Produce conveying mechanism for carrying vehicle body;

First in read/write head 2 is arranged on the initial station corresponding with producing conveying mechanism, and all the other are arranged on each operation position needing read/write head 2; Workman can carry out part installation to carrying the vehicle body of coming on operation position; In Fig. 1, a read/write head 2 on the left side is positioned at initial station, and that read/write head 2 on the right is positioned at an operation position; Read/write head 2 in this example comes from Pepperl & Fuchs Inc.;

Initial station and operation position all arrange display screen 3; Display screen 3 can adopt touching display screen; Display screen 3 and read/write head 2 one_to_one corresponding on this station;

The installation site of PLC4 and computer 5 does not have particular requirement, and the position suitable in automobile production workshop carries out installing.PLC4 is controller, has then pre-deposited each vehicle information, and can communicate with PLC4 in computer 5.

As shown in Figure 2, PLC4 is connected with computer 5 electric principle of the present invention; PLC4 connects read/write head on each station 2 and corresponding display screen 3; Read/write head 2 and data carrier 1 pass through twireless radio-frequency communication; Wherein, PLC4 is connected by fieldbus with read/write head 2;

Principle of work of the present invention is as described below:

1) read/write head 2 on initial station is when vehicle body passes through, in comprised vehicle information write data carrier 1, when vehicle body is by next station, the read/write head 2 on next station reads vehicle information, and direct labor determines the part installed according to the display of vehicle information; The quantity of these parts judged by the computer 5 be simultaneously connected with PLC4, the supply condition providing often kind of part according to the change of quantity that can be real-time.

2) in process of production, although vehicle body is flowing, but the vehicle information of each vehicle body is unique, the vehicle information read-out by read/write head recognition system passes to PLC, and PLC can track which position of vehicle body at workshop according to received vehicle information.
