- the rotation angle 01 between the first lower link 13 and the offset link 22 is fixed, and the glass 5 is attached to the rear window frame 7a.
- the rear window frame 7a Even if the angle of the glass 5 is different, the angle fine adjustment motor 61 is driven to rotate the outer link 2 2 B relative to the inner link 2 2 A.
- the attitude of the glass 5 with respect to the rear window frame 7a can be positioned with high accuracy, and the assembly quality of the glass 5 with respect to the rear window frame 7a can be improved.
- the workpiece transfer device 1 can be configured as follows.
- the workpiece transfer apparatus 1 includes the following balancer mechanism.
- this balancer mechanism the wire 73 is suspended between the traveling carriage 40 and the awakening tool 20, and the weight of the equipment 20 and the glass 5 is supported by the traveling carriage 40 via the wire 73.
- the arm 10 when the support arm 10 moves By canceling the weight, the load applied to the upper joint 15 in the support arm 10 is reduced.
- One end of the wire 73 is connected to the cart body 41 of the traveling cart 40, and the other end is connected to the fixture 20.
- a balancer cylinder 71 is attached to the cart body 41.
- the balancer cylinder 7 1 includes a cylinder body 7 1 a, a piston 7 1 b that can expand and contract with respect to the cylinder body 7 1 a, and a pulley 7 1 c that is attached to the tip of the piston 7 l b.
- the piston 7 l b expands and contracts in a substantially horizontal direction.
- the cart body 4 1 is also equipped.
- One wire 7 2 is provided, and the wire 7 3 is wound around the pulley 7 1 c and the pulley 7 2.
- the wire 7 3 wound around the pulley 7 1 c ⁇ 7 2 expands and contracts the piston 7 1 b of the balancer cylinder 7 1, so that the length between the pulley 7 2 and the »tool 2 0 Changes.
- the support arm 10 is Effectively reduces the weight applied to the support arm 10 regardless of whether the glass 5 is in the contracted state and the glass 5 is in the upward state, or the support arm 10 is in the vertically extended state and the glass 5 is in the downward state. Cancel) Yes.
- the position force in the assembly line L direction of the winding part of the wire 73 to the pulley 72 and the connection part to the jig 20 May end up. That is, the wire 73 below the pulley 72 supports the acid tool 20 and the glass 5 in a state where the tilt angle 0a is inclined from the vertically lower side.
- the cylinder 7 1 is attached to the base 4 1 so as to be movable in the assembly line L direction ⁇ ⁇ regardless of the operating state (attitude) of the support arm 10.
- the fixture 20 is configured so that the horizontal component F sin 0 a is not applied.
- the cylinder 7 1 and the pulley 7 2 are attached to the carriage main body 41 via a sliding member constituted by a guide rail 7 4 and the like, and the wire 7 3 below the pulley 7 2 is horizontally attached to the wire 7 3.
- the cylinder 7 1 and the pulley 7 2 move in a direction that cancels the force.
- the wire 7 3 can be placed vertically by configuring the bully 7 2 to be positioned directly above the connection point of the wire 7 3 at the tool 20. It can be hung, and it is possible to prevent the horizontal force from being applied to the fixture 20 and to stably carry and control the posture of the fixture 20.
- the present invention can be applied to a workpiece assembly apparatus that transports a workpiece in a wrinkled state to a workpiece assembly position and changes the posture of the workpiece to a posture according to the workpiece assembly position.
