It is described 3) in, while by the vehicle Data Enter after identification to be arranged on delivery vehicles RF tag in.
It is described 4) in, from current vehicle body delivery vehicles RF tag obtain it is no need carry out form switching instruction.
It is described 2) in, when transport agent rolls Measuring light screen away from, using clamping device fix delivery vehicles, and transport carry
Clamping device is unclamped when body is static.
The advantage of the invention is that cancel human assistance operation link, can automatic detection recognize more target vehicles, and
Detection recognition accuracy is improved, independent vehicle body positioning states switching equipment can combine site environment factor, along transmission line body cloth
Put, vehicle information reliable delivery is realized using REID.
Brief description of the drawings
The content to every width accompanying drawing expression in description of the invention is briefly described below：
Fig. 1 is vehicle body identification positioning switching system block diagram；
Fig. 2 is clamping device structural representation；
Fig. 3 is lifting device structural representation.
Embodiment
Vehicle body is placed on transport agent, transport agent orbiting, and transport agent is by detection identification station, vehicle body
Identification positioning switching system is located at detection identification station.
The track both sides of detection identification station porch are provided with Measuring light screen, and the processing of Measuring light screen combination software program is solved
The problem of multi-vehicle-type detection identification, selected Measuring light screen possesses (the integrated 384 photosignals detection of complete machine of high-resolution characteristic
Point, the Measuring light screen of 5mm resolution ratio, such as model KR/T5-1920), it can effectively recognize that the outline form between different automobile types becomes
Change.Measuring light screen carries out detection and localization one by one by switching hair number after installing, debugging to the vehicle body conveyed in production process.
The data fed back after detection carry out logic judgment by the software program of system design, just can met pair after receiving statistics
The function of multi-vehicle-type Division identification.
It is provided with below the track of detection identification station and vehicle body is raised out the lifting device of transport agent and braked to transport
RF tag is posted on the clamping device of transmission carrier, transport agent, detection identification station is provided with reading through being parked in station transport
The radio-frequency reading-writing device of RF tag on carrier, Measuring light screen outputs signal to controller, and controller outputs control signals to folder
Tight device and lifting device, radio-frequency reading-writing device communicate with controller.
RF tag and radio-frequency reading-writing device are used for the vehicle Data Enter after identification to penetrating installed in delivery vehicles
In frequency marking label, body shell matching corresponding with vehicle information carrier can be achieved.Positioning states switching device is judging to work as afterwards
Whether front of the car is when needing carry out state switching, it is necessary to by less radio-frequency read-write equipment, from current vehicle body delivery vehicles
RF tag obtains corresponding vehicle information, is used as the execution foundation of switching action this moment.
Lifting device is implemented to lift to the target vehicle body by needing position adjustment, can use 1 set of chain type lifting device, lead to
Cross after car body conveying system control delivery vehicles are moved forward or rearward certain size distance and stop, and pass through air clamper
Realization is accurately positioned, and finally vehicle body is reapposed on delivery vehicles again by lifting device, and remains in that conveying is carried
Body and the mutual pin-and-hole positioning states of vehicle body.After entire exercise is finished, with the appropriate mobile and positioning of delivery vehicles,
Target vehicle body positioning states can be by an original hole vehicle body positioning conversion for another hole vehicle body positioning, so as to meet
The different demands that weldering, painting, total manufacturing process (production and processing and parts assembling) are proposed to vehicle body positioning states.
Memory cell is provided with controller, memory cell contains vehicle profile information.The information of memory cell passes through
Debugging is obtained using Measuring light screen, is carried out detection and localization one by one to the vehicle body conveyed in production process by switching hair number, is passed through
The production process that different automobile types are carried out with 150 times respectively is detected, obtains detection data.The data progress packet to statistics is adopted afterwards
Sample, definition different automobile types, then each vehicle of software program logic judgment by designing therefrom are distinguished using the otherness for detecting data
Information, realization possesses multi-vehicle-type identification function.Before vehicle detection work is carried out, vehicle body is moved to identification work to be detected through conveying
Position stops, and delivery vehicles are fixed by air clamper, carries out vehicle body and is accurately positioned.On this basis, system completes above-mentioned car
Type detection identification work, and feed back the vehicle information that output meets related definition.
Debugging uses less radio-frequency read-write equipment and RF tag, and with reference to software program design, the vehicle after identification is believed
Typing is ceased in the RF tag of delivery vehicles.Positioning states switching device is judging whether current vehicle body needs afterwards
During carry out state switching, by less radio-frequency read-write equipment, obtain corresponding from the RF tag on current vehicle body delivery vehicles
Vehicle information, is used as the execution foundation of switching action this moment.
Stop when vehicle body conveying is moved to vehicle body positioning states adjustment station, debugging fixes defeated using air clamper
Carrier is sent, vehicle body is carried out and is accurately positioned.RF tag on vehicle body delivery vehicles is read by less radio-frequency read-write equipment, known
Current vehicle information.Defined according to system, when vehicle information meets positioning hole adjustment demand, debugging is worked using lifting device
Vehicle body is departed from into delivery vehicles.After disengaging, air clamper is opened, and delivery vehicles control mobile and detect stopping by system
(being equally accurately positioned after stopping through air clamper).Delivery vehicles stop after positioning, and lifting device works vehicle body again
It is forwarded on delivery vehicles, pin-and-hole positioning states is kept each other.After entire exercise is finished, vehicle body positioning states, which change, to be completed,
By an original hole vehicle body positioning conversion for another hole vehicle body positioning, so as to meet weldering, the painting, (life of total manufacturing process
Production processing and parts assembling) different demands that vehicle body positioning states are proposed.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented not by aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or without changing
Enter and the design of the present invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
