Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention makes a final pass/fail judgment of a completed vehicle, determines whether the specifications of a part vehicle are in accordance with preset specifications, and collects various inspection data. The present invention relates to a device that determines whether or not all 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 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.
Painting and mounting are carried out according to the specifications written on the card, but if a worker issues the production instruction card to the wrong party or misreads the specifications, the vehicle specifications may be set. Therefore, the inspector looks at the body number attached to the vehicle and the specification sign indicating the model number and other specifications attached to the equipment installed in the vehicle, such as the engine, and determines the actual vehicle.・We check whether the actual specifications match the set specifications.

As an inspection device for that purpose, JP-A-58-149145
The publication is equipped with a card reader that reads the specifications written on the production instruction card and a voice recognition device, and when an inspector sees the vehicle body number or specification sign and reads it out loud, the voice recognition device can read the contents. The data from the card reader is compared with the data from the voice recognition device using a determination device to determine whether the actual specifications match those written on the production instruction card. is 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 the data of various performance tests, the results of specification judgments were written on the inspection result card issued for each vehicle.
Generally, inspectors check these data and make final pass/fail judgments, but in this case, there is a possibility that checking errors may occur, which poses problems in terms of quality assurance.

The present invention automatically inspects the specifications and checks various inspection data written on the inspection result card without requiring a full-time inspector, and enables accurate and efficient pass/fail judgment of completed vehicles. The purpose is to provide a device that

(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 visual sensor, an eye reader that reads data from the visual 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.

In addition, if you insert the inspection results card into a card reader, the various inspection data written on the card will be input into the judgment device via the card reader, and it will be confirmed that all of this inspection data meets the standards and the actual specifications are set in advance. If the specifications are as set,
Pass is displayed on the display.

(Example) Referring to FIG. 1, (1) shows a robot with a visual sensor (2) attached to its tip, and when the robot (1) operates, the visual sensor (2) is attached to the identification number of the vehicle W. Move to stamping position 1 of the body number of the barrel, stamping position b of the model number of equipment installed in the vehicle such as engine and transmission, position 0 of the paint color display label, etc., and check the body number and these model numbers and display. A specification mark indicating the specifications of the vehicle W, such as a label, is visually recognized by the visual sensor (2).

Referring to Figure 2, (3) is an eye reader that reads data from the visual sensor (2), and (4) is the brake inspection and instrumentation information written on the inspection result card (5) issued for each vehicle. It shows a card reader that reads various inspection data such as inspection, and inputs the data from the eye reader (3) and the card reader (4) to the determination device (6), and the determination device! (6)
The system determines whether the specification sign visually recognized by the visual sensor (2) conforms to the specification set in advance according to the vehicle body number, that is, whether the actual specification matches the set specification, and various inspection data. determine whether or not it meets the standards,
The determination result is displayed on the display (7).

The determination of the specifications by the determination device (6) reads out the specification data of the vehicle with the vehicle body number visually recognized by the visual sensor (2) from among the specification data of each vehicle input to the mask computer (8), and This is done by comparing this specification data with the specification sign visually recognized in (2), or by reading the vehicle body number and specification data written on the production instruction card issued for each vehicle with a card reader (4). Then, the vehicle body number and specification mark visually recognized by the sensor (2) are compared with the vehicle body number and specification data read by the card reader (4).

Next, the inspection data is judged. In this case, it is first determined whether or not it matches the vehicle body number written on the inspection result card (5). If it matches, the data is written on the card (5). Determine whether or not each of the various inspection data meets the standards, and when all inspection data meets the standards and the actual specifications match the set specifications,
Display device (indicates that the sword has passed, and also displays the necessary information on the inspection result card and the number of the equipment on board the vehicle)
8).

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

In the above embodiment, the vehicle body number stamped on the vehicle body was used as the identification number of the vehicle W, but if the vehicle body W has another number that can be identified, this may be used as the identification number. Of course, it is also possible.

(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.
