Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is provided with a door transport means for holding and transporting the door so that the hinge member of the vehicle body and the hinge member of the door are engaged with each other. The present invention relates to a door assembly device for a motor vehicle, which is provided with control means for actuating the transfer means to a door receiving location and a door engaging location based on information.

[Conventional technology]

This type of automobile door assembling device automates the complicated door assembling work to save labor and improve efficiency.

When the door is moved to engage both hinge members while operating the transfer means by the control means, if the transfer means is operated based on certain stored information, the door may be moved due to positional deviation of the vehicle body at the engagement point. There is a method in which it is not possible to engage both hinge members in a predetermined manner.

In order to avoid such inconvenience, it is conceivable that a measuring means for measuring the position of the hinge member of the vehicle body is installed at the engagement point, and the stored information of the control means is corrected based on the measured information. .

[Problem to be solved by the invention]

Even if the measuring means is installed at the engagement point and the stored information of the control means is corrected based on the measured information, there is a possibility that it will be difficult to perform the predetermined engagement due to the following reasons.

The cause of this is that the information stored in the control means becomes incorrect due to mechanical distortion of the transfer means during use, and that the control accuracy of the transfer means is not sufficiently accurate due to mechanical manufacturing errors of the transfer means. The main reason can be cited as the inability to improve. In the former case, it is possible to solve the problem by optimizing the stored information by frequently performing teaching, but this results in a decrease in work efficiency. In the latter case, it is possible to solve the problem by sufficiently increasing the manufacturing precision of the transfer means, but this has the disadvantage that the overall structure becomes expensive.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to enable accurate engagement work while avoiding the disadvantages of lowering work efficiency and increasing the cost of the overall structure. It is in.

[Means to solve the problem]

A control means is provided to operate the control means at the door receiving location and the door engagement location, and its characteristic configuration is that the transfer means is provided with a measuring means for measuring the position of the hinge member of the vehicle body, and the The control means is configured to correct the stored information based on the measurement information of the measurement means.

The effects of the above characteristic configuration are as follows.

[For production]

The position of the hinge member of the vehicle body located at the engagement point is measured by the measuring means provided on the transfer means, and the stored information for operating the transfer means is corrected based on the measured information.

Since the measuring means is provided in the transport means itself, that is, the position of the hinge member of the vehicle body can be measured by the measuring means by operating the transport means at the door engagement point. Due to mechanical distortion of the means, the stored information of the control means is incorrect, or mechanical manufacturing errors of the transfer means make it impossible to sufficiently improve the control accuracy of the transfer means. Even if there is a positional shift in the transfer means operated at the door engagement point, the relative position of the transfer means with the position shift and the hinge member of the vehicle body is measured by the measuring means, and the stored information is stored based on the measured information. can be corrected to operate the transport means for engagement of both hinge members.

〔Effect of the invention〕

Therefore, as described in the above operation, even if there is a positional deviation in the transfer means operated at the door engagement point, the relative position of the transfer means with the position deviation and the hinge member of the vehicle body is measured by the measuring means, Since the stored information can be corrected based on the measurement information and the transfer means can be operated to hold both hinge members together, both hinge members can be operated regardless of the positional deviation of the actuated transfer means at the door engagement point. can be engaged appropriately.

Since these advantages can be achieved without frequent teaching and without increasing the manufacturing precision of the transfer means, accurate engagement can be achieved while avoiding the disadvantages of reduced work efficiency and an expensive overall configuration. This makes it possible to carry out joint work, and as a result, an automobile door assembling device with great practical advantages has been obtained.
