In a flexible manufacturing system for assembling various types of vehicle bodies, there is employed a work piece carrier on which a work piece positioning device is mounted. The work piece positioning device has a plurality of position changeable work piece holders which are grouped into a plurality of groups each having its own power input device. When the carrier comes to a type switching state together with the work piece positioning device, a power source installed in the type switching stage is brought into connection with the power input device of one of the groups thereby to change the positions of the corresponding work piece holders. Then, the power source is brought into connection with the other power input device of the other group to change the positions of the corresponding work piece holders.

In order to facilitate rapid automatic set up and adjustment of a robotic assembly arrangement in a manner which produces the required precision, pre-recorded data and expert system software are teamed together and used to set robotic support jigs and move panels into position against the body they are to be attached to. The position of the panels is determined using a laser scanning technique and feedback control used to adjust the robots and associated hardware and move the panel or panels in the case there is a deviation beyond acceptable tolerances in a manner which either reduces or eliminates the deviation.

For holding a plurality of different, in shape, workpieces, a holding unit comprises a laminated body with a number of thin identical shaped elongate plates which have one ends forming a workpiece supporting surface, a vibrator unit for moving the elongate plates so as to vary the shape of the workpiece supporting surface to create a new one, and a bias mechanism for clamping the laminated body, so the newly created shape of the workpiece supporting surface is maintained.

An apparatus for and a method of automatically assembling a body structure of an automobile body, in which side panels are downwardly conveyed into first temporary positions over a floor panel and adjacent jig means, adjusted for proper positions relative to the jig means, moved into second temporary positions, clamped by the jig means, moved from the second temporary positions into final working positions ready to be welded to the floor panel which has been conveyed into a working position thereof, and welded to the floor panel into a unitary structure. The side panels are initially held in positions horizontally close to each other and are gradually moved toward positions horizontally spaced wider from each other as the side panels are conveyed downwardly. The apparatus and method may be modified so that not only the floor panel and the side panels by a cowl-and-dash-panel subassembly and/or a parcel shelf member are assembled together.

A method and system for automatically attaching works to respective vehicle bodies carried on a slat conveyor using a robot. The method comprises the steps of (a) providing a base on which the robot is mounted and which is movable within a movement range, at least one part of which is alongside of the conveyor; (b) providing work feeders for sequentially feeding plural kinds of the works which are different according to vehicle types (sedan, hardtop, etc.) of the vehicle bodies to predetermined positions; (c) identifying the vehicle type of one of the vehicle bodies to which the required work is to be attached at a first position; (d) determining a target position according to the identified vehicle type; (e) controlling the robot so as to grasp the required work from the work feeders at the target position; (f) positioning the robot to a stand-by position along the conveyor; (g) detecting sequentially a deviation of a relative position toward a direction of travel of the conveyor between a tracking point and reference point since the vehicle body has arrived at a second position downstream of the first position; and (h) moving the base to follow the conveyor so that the deviation becomes zero and simultaneously controlling the robot so as to attach the grasped work to the vehicle body.
摘要:
A vehicle body is assembled in a number of stages each including robots which are automatically adjusted to move and secure work pieces such as panels to a basic body member or chasis. One of the stages includes a measuring arrangement which scans the assembled unit with laser beams to determine if the required tolerance have been set. In the event of deviations beyond permissible limits the appropriate correction is derived and fed back to the stage wherein the securing operation in question occured.

A method of and an apparatus for assembling a vehicle body is disclosed, which uses a laser welding equipment to join panels of a vehicle body main part. The panels are located and held by a gauge portion of a workpiece supporting jig and are welded at a held portion by means of a laser beam conducted through the workpiece supporting jig.
