Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is applicable to the final pass/fail judgment of a completed vehicle, that is, whether or not the specifications of the vehicle are in accordance with preset specifications, and the comprehensive inspection of various inspection data. The present invention relates to a device that determines whether or not standards are met.

(Prior art) Conventionally, when manufacturing vehicles such as automobiles, specification data such as the model of equipment such as the engine installed in each vehicle and paint color are stored in a master computer for each vehicle using the vehicle body number attached to the vehicle as index data. A production instruction card with this specification data printed out is issued for each vehicle, and painting and outfitting are performed according to the specifications written on the card. Sometimes the specifications of the vehicle may differ from the set specifications due to a mistake in the first part or the misreading of the specifications.
A test is performed to determine whether the actual specifications of the vehicle match the set specifications by looking at a specification sign indicating specifications such as a model number attached to equipment mounted on the vehicle such as an engine.

As an inspection device for this purpose, we developed the
According to Publication No. 149145, it is equipped with a card reader that reads the specifications written on the production instruction card and a voice recognition device, and when the inspector sees the vehicle body number or specification sign and reads it out, the voice recognition device reads the contents. A judgment device compares the data from the card reader with the data from the voice recognition device to determine whether the actual specifications match those written on the production instruction card. Things are known.

(Problems to be Solved by the Invention) In the above method, only an inspector who has registered the tone color in the voice recognition device can perform the work, which poses a problem in improving productivity.

Additionally, in the past, in addition to data from various performance tests, specification judgment results were entered on the inspection result card issued for each vehicle, and inspectors checked this data to make a final pass/fail judgment. However, due to human intervention, there is a possibility of checking errors, which poses problems in terms of quality assurance.

The present invention automatically inspects the specifications and checks the data of various inspections written on the inspection result card without requiring a full-time inspector, thereby making it possible to accurately and efficiently judge the pass/fail of completed vehicles. The purpose is to provide a device that achieves this goal.

(Means for Solving the Problems) In order to achieve the above object, the pass/fail determination device of the present invention uses a vehicle identification number such as a body number attached to a vehicle, and a vehicle identification number attached to a vehicle-mounted equipment such as an engine. A robot equipped with a vision sensor, an eye reader that reads data from the vision sensor, and a card that reads various inspection data written on the inspection result card issued for each vehicle. Input data from the reader, the eye reader, and the card reader, and determine whether the specification sign visually recognized by the visual sensor conforms to the specifications set in advance according to the identification number, and perform various inspections. It consists of a determination device that determines whether or not data meets standards, and a display that displays the determination results of the determination device.

(Operation) A visual sensor is moved to each predetermined part of a completed vehicle by the operation of a robot, and the identification number and specification mark attached to these parts are sequentially captured by the visual sensor. Data from the visual sensor is input to the determination device via the eye reader, and it is determined whether the actual specifications match the preset specifications.

Also, if you insert the inspection results card into a card reader, the various inspection data written on the card will be input to the judgment device via the card reader, and it will be confirmed that all of these inspection data meet the standards and match the actual specifications. If it meets the pre-set specifications, the display will show "Pass".

(Example) Referring to FIG. 1, reference numeral 1 denotes a robot having a visual sensor 2 attached to its tip, and when the robot 1 operates, the visual sensor 2 is placed at a position a where the vehicle body number, which is the identification number of the vehicle W, is stamped. , move to the stamping position b of the model number of the vehicle-mounted equipment such as the engine and transmission, and the pasting position c of the paint color display label, etc., and check the vehicle body number and the vehicle W such as these model numbers and display labels. The visual sensor 2 visually recognizes a specification mark representing the specifications of the vehicle.

Referring to FIG. 2, 3 is an eye reader that reads data from the visual sensor 2, and 4 reads various inspection data such as brake inspection and instrument inspection written on an inspection result card 5 issued for each vehicle. Indicates a card reader, inputs data from the eye reader 3 and card reader 4 to a determination device 6, and determines in advance the specification mark visually recognized by the visual sensor 2 by the determination device 6 according to the vehicle body number. It is determined whether the sign conforms to the specifications, that is, whether the actual specifications match the set specifications, and whether the various inspection data meet the standards, and the determination results are displayed on the display 7. It is now displayed on .

The determination device 6 determines the specifications by reading out the specification data of the vehicle with the chassis number visually recognized by the visual sensor 2 from among the specification data of each vehicle input into the master computer 8, and determining the specifications visually recognized by the sensor 2. This is done by comparing the sign with this specification data, or by reading the car body number and specification data written on the production instruction card issued for each vehicle with a card reader 4, and checking the car body visually recognized by the sensor 2. This is done by comparing the number and specification mark with the vehicle body number and specification data read by the card reader 4, respectively.

Next, the inspection data is judged. In this case, it is first determined whether the vehicle body number written on the inspection result card 5 matches the vehicle body number visually recognized by the visual sensor 2, and if it matches, It is determined whether or not each of the various inspection data entered on the card 5 satisfies the standards, and all the inspection data satisfy the standards and the actual specifications match the set specifications. At that time, the display 7 displays “Pass”.
Furthermore, the necessary items of the inspection result card and the numbers of the equipment mounted on the vehicle are inputted into the master computer 8.

Further, if the specifications are incorrect or the inspection data does not meet the standards, this fact is displayed on the display 7.

Incidentally, in the above embodiment, the vehicle body number stamped on the vehicle body was used as the identification number of the vehicle W, but when the vehicle body W has another number that can be identified,
Of course, it is also possible to use this as an identification number.

(Effects of the Invention) As described above, according to the present invention, it is possible to determine whether or not the actual specifications of the vehicle conform to the preset specifications, and to check whether the various inspection data entered on the inspection result card conforms to the standards. It is possible to automatically and accurately determine whether or not the inspection results are satisfied without requiring a dedicated inspector, and has the effect of reliably resolving the problems of the prior art described above.
