Abstract

PURPOSE:To obtain an automatic robot inspecting system which can perform the single-element control of information and preserves the state at an instant when an error is generated. CONSTITUTION:A built-in memory is attached to a pallet 4 for conveying a robot controller 3. An ID card 5 stores the production control data such as the kinds of robots and can accommodate the data of the results of inspections. An ID card terminal 6 is provided. A computer 8 preserves the inspecting items and the inspecting conditions for every kind of the robot and preserves the production control data, the inspecting conditions, the data of the results of the inspections and the like in one file after the end of the inspections. These parts are provided for the memory. The data of the results of the inspections in a aging mode are stored and refleshed at every relatively short constant time in a buffer memory. When an error is generated, the buffer memory is fixed, and the data of the results of the inspections at an instant when the error is generated are preserved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic robot inspection system.

[0002]

2. Description of the Related Art Conventionally, a robot is generally inspected by an operator setting inspection conditions for each inspection item. Further, when an error occurs in the operation of the robot during the inspection in the aging mode, it was not possible to know how the inspection result data changed before or at the time when the error occurred compared to the normal time. That is, it was impossible to know the situation at the moment when an error occurred in the robot.

[0003]

With such a conventional inspection method, it is difficult to centrally manage the robot model, production control data, inspection conditions, inspection result data, and the like. Also, if an error occurs in the robot operation during inspection in the aging mode, it is not possible to know how the inspection result data changed before or at the time of the error compared to the normal time, and promptly It was an obstacle to taking various measures.

The present invention solves the above-mentioned conventional problems, and provides an automatic robot inspection system capable of centrally managing information and knowing inspection result data before or at the moment when an error occurs. The purpose is to provide.

[0005]

In order to achieve the above object, an automatic robot inspection system according to the present invention is attached to a pallet carrying a robot or a robot controller to be inspected, and a built-in storage device is a robot and a robot. An ID card that stores production management data such as the controller model, machine number, and manufacturing date, and that has a space to store the inspection result data of the inspection, and an ID that reads or writes the data of the ID card. The card terminal and the inspection items and inspection conditions for each robot model are stored, and after the inspection,
It is provided with a computer for collectively storing production management data, inspection conditions, inspection result data and the like in one file.

In addition, the inspection result data in the aging mode is stored and refreshed in the buffer memory at relatively constant intervals, and when an error occurs in the operation of the robot, the contents of the buffer memory at that time are fixed.

[0007]

With the above-described structure, the automatic inspection system for robots according to the present invention allows the computer to centrally manage information, and when an error occurs in the operation of the robot, the contents of the fixed buffer memory cause an error. You can know the situation at the time of occurrence.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an automatic inspection system for a robot according to the present invention. Reference numeral 1 denotes a robot, which enters a inspection system by riding on a robot pallet 2 carried by a robot conveyor 9. Reference numeral 3 denotes a robot controller that is set with the robot 1. The robot controller 3 rides on the controller pallet 4 carried by the controller conveyor 10 and enters the inspection system in synchronization with the robot 1. An ID card 5 is fixed on the controller pallet 4, and a built-in storage device stores production management data such as the model of the robot 1 and the robot controller 3, the machine number, and the manufacturing date. It also has a space for storing the inspection result data of the inspection to be performed. The stored data is the data input through the ID card terminal in the previous process (not shown).

Reference numeral 6 denotes an ID card terminal provided in this inspection system, which reads the above-mentioned data stored in the ID card 5 and writes the inspection result data measured by this inspection system in the ID card 5. Reading or writing of data is normally performed optically without contact. Reference numeral 7 is a measuring device for measuring the inspection result, 8 is a computer for controlling the inspection system, and the inspection items and the inspection conditions to be performed according to the models of the robot 1 and the robot controller 3 stored in the ID card 5 are already stored. It is entered in the device.

Robot 1 and robot controller 3
When arrives at the inspection system, the computer 8 reads the data stored in the ID card 5 through the ID card terminal 6. The computer 8 knows the model of the robot that has arrived from this data, instructs the robot controller 3 about the inspection items and inspection conditions to be performed, operates the robot 1, and starts the inspection. After the inspection is completed, the computer 8 collectively stores the production control data, the inspection conditions, the inspection result data and the like in one file.

The flow of the inspection carried out by this inspection system is shown in FIG.
However, it can be divided into two modes (normal mode and aging mode). Normal mode is
In this mode, the inspection is performed by performing a relatively simple operation for each model of the robot 1. The aging mode is a mode in which the robot 1 that has passed the inspection in the normal mode is inspected while repeatedly performing complicated operations for a predetermined time.

Since the inspection in the aging mode usually takes a considerably long time, it is practically impossible to save all the inspection result data continuously during that time, and it has not been conventionally performed. Therefore, if an error occurs in the operation of the robot 1 during the inspection in the aging mode,
It is not possible to know how the test result data changed before or at the moment when an error occurred, compared to the normal case. In the inspection system of the present invention, the computer 8 saves and refreshes the inspection result data in the aging mode in a buffer memory (not shown) at a relatively short constant time interval, and when an error occurs, saves the buffer memory at that time. The content is fixed. As a result, it is possible to know how the inspection result data changes before or at the moment when an error occurs compared to the normal time.

[0013]

As is apparent from the above description, in the automatic robot inspection system of the present invention, the computer collectively saves production management data, inspection conditions, inspection result data, etc. Centralized management is easy. In addition, the inspection result data in the aging mode is stored and refreshed in the buffer memory at relatively constant intervals, and when an error occurs, the contents of the buffer memory at that time are fixed. This makes it possible to know the inspection result data before or at the moment when an error occurs with a small memory capacity.
