In this case, the worker works according to different assembly instructions for each product.

However, in such a production method,
No matter how skilled the worker is, it is impossible to completely avoid work mistakes. For example, there is a risk that the assembly procedure of the parts may be incorrect or parts of different products may be assembled. Further, when inspecting whether or not the tightening torque of the assembled bolt is within a predetermined range, an operator reads the torque from a meter, and the value is a predetermined value defined in the assembly manual. Since it is determined whether or not it is within the range, a determination error may occur.

In view of the above, an apparatus for displaying an operation procedure by a video to an operator to prevent an error in an assembly procedure, and an inspection data are displayed on a display so as to facilitate an operation of confirming the data. And a device that reads a unique number of a component from a component and performs an instructed process based on the device.

However, each of the conventional devices has an independent device configuration. For example, while the operation procedure is displayed on one display device, the operation result of the operation is displayed on another display device. Since the display is performed, the operator has to check both of these displays, and the work is accordingly complicated, and there is a possibility that a work error is likely to occur.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned problems, and makes it easy to confirm the work contents and the work results, and to avoid the occurrence of work errors. It is an object to provide a work assist device.
