Abstract

An assembly apparatus is constituted to include positioning mechanisms for aligning the positions of side panels and a roof panel. For example, a front positioning mechanism includes a first base portion disposed on a first distal end arm of a front side robot, roof positioning members and side panel positioning members supported displaceably by the first base portion, a right front beam member and a left front beam member extending along a vehicle widthwise direction from the first base portion, a first left marking member and a first right marking member disposed at respective distal ends of the beam members, and a left visual sensor and a right visual sensor for detecting positions of each of the first left marking member and the first right marking member.

Claims

1. An assembly apparatus for assembling a vehicle body by attaching a roof panel to side panels, and comprising a positioning mechanism for aligning positions of the side panels and the roof panel, wherein the positioning mechanism comprises:

a robot;

a base portion attached to a distal end arm of the robot;

roof positioning members supported on the base portion on outer sides thereof in a vehicle widthwise direction for positioning the roof panel;

side panel positioning members supported on the base portion on outer sides thereof in the vehicle widthwise direction for positioning the side panels;

a first beam member and a second beam member extending along the vehicle widthwise direction from the base portion;

a right marking member disposed on a distal end of the first beam member;

a left marking member disposed on a distal end of the second beam member;

a left visual sensor configured to detect a position of the left marking member; and

a right visual sensor configured to detect a position of the right marking member;

wherein the left visual sensor and the right visual sensor are disposed respectively on left and right sides of the vehicle body.

2. The assembly apparatus according to claim 1, further comprising a moving mechanism which is capable of moving the vehicle body along a longitudinal direction of the vehicle body, together with a first groove and a second groove being formed respectively on right and left sides in the vehicle widthwise direction of the moving mechanism;

wherein the left visual sensor and the right visual sensor and the robot are installed externally of the first groove and the second groove.

3. The assembly apparatus according to claim 1, wherein the left visual sensor and the right visual sensor are cameras.

4. The assembly apparatus according to claim 1, wherein:

the left visual sensor comprises a lower left visual sensor having an optical axis which is oriented upward, and being configured to detect front and rear and left and right displacements of the left marking member, and an upper left visual sensor having an optical axis which is oriented inwardly in the vehicle widthwise direction, and being configured to detect front and rear displacements and vertical displacements of the left marking member;

the right visual sensor comprises a lower right visual sensor having an optical axis which is oriented upward, and being configured to detect front and rear and left and right displacements of the right marking member, and an upper right visual sensor having an optical axis which is oriented inwardly in the vehicle widthwise direction, and being configured to detect front and rear displacements and vertical displacements of the right marking member; and

the upper right visual sensor is supported by a first support column, and the upper left visual sensor is supported by a second support column.

5. The assembly apparatus according to claim 4, wherein the left marking member includes a lower left marking detected by the lower left visual sensor, and a left side marking detected by the upper left visual sensor, and the right marking member includes a lower right marking detected by the lower right visual sensor, and a right side marking detected by the upper right visual sensor.

6. The assembly apparatus according to claim 4, wherein the lower left visual sensor, the upper left visual sensor, the lower right visual sensor, and the upper right visual sensor are cameras.

7. The assembly apparatus according to claim 1, wherein the left marking member and the right marking member are arranged more outwardly in the vehicle widthwise direction than the roof positioning members and the side panel positioning members.

8. The assembly apparatus according to claim 1, wherein the roof positioning members are configured to be displaced along the vehicle widthwise direction and a vehicle heightwise direction, and the side panel positioning members are configured to be displaced along the vehicle widthwise direction.

9. The assembly apparatus according to claim 8, wherein the roof positioning members and the side panel positioning members are configured to be displaced by a ball screw mechanism, a rack and pinion mechanism, or an air cylinder mechanism.
