Embodiment 1

[0039] like figure 1 As shown, a vehicle body space position intelligent detection device of the present invention includes a transportation line 1 , a vehicle body detection device 2 , a PLC control cabinet and an RFID reader-writer 3 .

[0040] The RFID reader 3 is used to identify the label number of the transport trolley and the model of the painted workpiece. In this embodiment, the RFID reader-writer 3 is a Pepperl+Fuchs code reader, and the RFID reader-writer is set on one side of the transport line facing the label on the transport trolley. like figure 2 As shown, the RFID reader 3 is electrically connected to the analog input terminal of the PLC control cabinet. The RFID reader-writer 3 uses the PROFIBUS communication protocol to communicate with the PLC control cabinet. In this embodiment, the vehicle body detection station is the erection position of the door frame photoelectric scanner 21; when the transport trolley arrives at the vehicle body detection station...

Embodiment 2

[0053] On the basis of Embodiment 1, this embodiment adopts the intelligent detection device of Embodiment 1 to realize an intelligent detection method for the spatial position of the vehicle body, including the following steps:

[0054] S1. The door frame photoelectric scanner 21 scans the painted workpiece loaded on the transport trolley m times, generates a set of scan data for each scan, extracts the features of the scan data, and establishes a mathematical model according to the features;

[0055] The installation position of the painted workpiece on the transport trolley is correct or incorrect;

[0056] Wherein, the scan data includes a group of binary data; the binary data represents the conduction of n laser photoelectric switches 21-2 on the door frame photoelectric scanner 21, and "1" represents the conduction of the laser photoelectric switches 21-2, "0" represents that the laser photoelectric switch 21-2 is not turned on;

[0057] In this embodiment, the features...

Embodiment 3

[0073] This embodiment provides an application of an intelligent detection device for the spatial position of a vehicle body. The intelligent detection device for the spatial position of a vehicle body is applied in the automobile bumper painting process.

Abstract

The invention provides a vehicle body spatial position intelligent detection device and method and application thereof. Specifically, the information of each trolley is read through an RFID reader-writer, and then the information is compared with the information detected by a laser correlation photoelectric switch; if consistent, the detection is passed; and if inconsistent, the position and the mounting condition of a coating workpiece on the transport trolley along the vertical direction can be obtained through the triggering condition of the n laser correlation photoelectric switches; the position of the coating workpiece in the horizontal direction can be obtained through the triggering conditions of m proximity switches, meanwhile, an alarm is given, and a conveying chain of the section is stopped, thus facilitating confirmation by the production personnel, and preventing waste of manpower, energy and the like caused by collision, scrappage and re-spraying due to poor workpiece feeding or poor hanging tool flowing into coating; compared with a purely-used visual system, the device is simple, good in reliability, high in flexibility, low in cost and convenient to maintain; theplurality of proximity switches are arranged on the transport line, multi-point detection can be achieved, and the transverse fault-tolerant capacity is high.

Description

technical field [0001] The invention relates to the field of automobile bumper vehicle body detection, in particular to an intelligent detection device, method and application of the space position of the vehicle body. Background technique [0002] At present, before the automobile bumper is painted, the parts to be painted need to be put on the hanger, and then the painting process is completed through the painting line. However, in practical applications, misplacement of the painting hanger, misplacement of the column hole, misplacement of the product and the failure of the product to be in place have occurred from time to time, resulting in parts being dropped and The robot in the spray booth crashes and grabs. Therefore, in order to solve the above problems, the present invention provides a vehicle body space position intelligent detection device, method and application thereof, the upper part of the painting hanger is wrong, the hole position of the column is wrong, th...
