Abstract

A jig apparatus is used for assembling a trunk lid including an upper panel, an extension panel, and a lower panel. The jig apparatus may include: a jig frame; a first activation jig unit configured to align and fix the upper panel and the extension panel and installed at the jig frame in front and rear directions to be tilting-rotatable; and a second activation jig unit aligning and fixing the lower panel and installed at the jig frame to be linearly movable in the front and rear directions with respect to the first activation jig unit.

First claim

What is claimed is:

1. A jig apparatus for assembling a vehicle trunk lid including an upper panel, an extension panel, and a lower panel, comprising:
a jig frame;
a first activation jig unit configured to align and fix the upper panel and the extension panel and installed at the jig frame in front and rear directions to be tilting-rotatable; and
a second activation jig unit configured to align and fix the lower panel and installed at the jig frame to be linearly movable in the front and rear directions with respect to the first activation jig unit.

2. The jig apparatus for assembling the trunk lid of claim 1 , wherein:
the first activation jig unit aligns and fixes the upper panel and the extension panel so that a lower end edge of the upper panel and a first side edge of the extension panel are mutually overlapped,
in a state in which the first activation jig unit is tilting-rotated in a direction away from the second activation jig unit, the upper panel and the extension panel are aligned and fixed.

3. The jig apparatus for assembling the trunk lid of claim 1 , wherein:
the second activation jig unit aligns and fixes the lower panel so that the lower panel faces a second side edge of the extension panel, and
in a state in which the first activation jig unit is tilting-rotated in a direction approaching the second activation jig unit,
the second activation jig unit is linearly moved a first activation jig unit side and presses the lower panel to the second side edge of the extension panel.

4. The jig apparatus for assembling the trunk lid of claim 1 , wherein:
in the first activation jig unit, primary laser brazing is performed for an overlapping part of the upper panel and the extension panel through a brazing assembly, and
secondary laser brazing is performed between the first and second activation jig units through the brazing assembly for a facing part of the lower panel and the extension panel.

5. A jig apparatus for assembling an upper panel, an extension panel, and a lower panel of a vehicle trunk lid by laser brazing, comprising:
a jig frame;
a first activation frame having a first jig base supporting the upper panel and the extension panel and installed at the jig frame in front and rear directions to be tilting-rotatable;
a second activation frame having a second jig base supporting the lower panel and installed corresponding to the first activation frame at the jig frame to be linearly movable in the front and rear directions;
a plurality of aligning units respectively installed at the first and second activation frames, aligning the upper panel and the extension panel in a predetermined position of the first jig base, and aligning the lower panel in a predetermined position of the second jig base; and
a plurality of clampers respectively installed at the first and second activation frames, fixing the upper panel and the extension panel at the first jig base, and fixing the lower panel at the second jig base.

6. The jig apparatus for assembling the trunk lid of claim 5 , wherein:
a first driving cylinder is installed at both of right and left sides of the jig frame to be connected to the first activation frame and tilting-rotating the first activation frame in the front and rear directions.

7. The jig apparatus for assembling the trunk lid of claim 6 , wherein:
the first activation frame is coupled to the jig frame through a tilting rotation axis to be tilting-rotatable, and
the first driving cylinder is connected to both ends of the tilting rotation axis through a rotation bracket and applies a forward/backward activation force in front and rear directions to a rotation bracket through an actuating rod.

8. The jig apparatus for assembling the trunk lid of claim 5 , wherein:
the second activation frame is installed in the fixing frame on the jig frame to be movable back and forth in the front and rear directions through a guide rail, and
a second driving cylinder connected to the second activation frame and applying a forward/backward activation force to the second activation frame in the front and rear directions is installed at both of right and left sides of, fixing frame.

9. The jig apparatus for assembling the trunk lid of claim 5 , further comprising:
a locking unit installed fixing frame and selectively locking the first activation frame to the fixing frame,
wherein the locking unit is hinge-coupled to a locking cylinder installed at the fixing frame and an actuating rod tip of the locking cylinder and includes a locking block installed at the fixing frame to be rotatable.

10. The jig apparatus for assembling the trunk lid of claim 9 , wherein a docking block through which locking and unlocking is selectively performed with the locking block is installed at the first activation frame.

11. The jig apparatus for assembling the trunk lid of claim 5 , wherein the aligning units include:
a first aligning unit installed at the first activation frame and aligned so that a lower end edge of the upper panel overlaps a first side edge of the extension panel; and
a second aligning unit installed at the second activation frame and aligned so that the lower panel faces a second side edge of the extension panel.

12. The jig apparatus for assembling the trunk lid of claim 11 , wherein the dampers include:
a first damper installed at the first activation frame and respectively clamping the upper panel and the extension panel; and
a second damper installed at the second activation frame and clamping the lower panel.

13. The jig apparatus for assembling the trunk lid of claim 12 , wherein the first damper includes:
a plurality of first clamping blocks installed at the first activation frame to be rotatable by a first clamp cylinder and pressing a flat part of the upper panel;
a plurality of second clamping blocks installed to be rotatable at the first activation frame by a second clamp cylinder and pressing a bent part of the upper panel; and
a plurality of third clamping blocks installed to be rotatable by a third clamp cylinder at the first activation frame and pressing an overlapping part of the bent part of the upper panel and the extension panel.

14. The jig apparatus for assembling the trunk lid of claim 13 , wherein:
the third clamping blocks form a clamping line connected in a streamlined shape along the overlapping part of the bent part of the upper panel and the extension panel.

15. The jig apparatus for assembling the trunk lid of claim 13 , wherein the first damper further includes:
at least one clamp finger installed at the first activation frame to be rotatable by a fourth clamp cylinder, rotating in the front and rear directions through the first jig base, and pressing the extension panel.

16. The jig apparatus for assembling the trunk lid of claim 15 , wherein:
the second damper includes a plurality of clamp plates installed at the second activation frame to be rotatable by a fifth clamp cylinder and pressing the upper panel in a plan view.

17. The jig apparatus for assembling the trunk lid of claim 11 , wherein the first aligning unit includes:
