Detailed Description of the Invention (Industrial Field of Application) The present invention provides an automatic terminal insertion device for a connector for transferring an electric wire with a terminal attached to the tip of the electric wire to an automatic terminal insertion device for the connector. This invention relates to a delivery device for electric wires with terminals.

(Prior art) For example, when forming a wiring harness for an automobile, as shown in FIG. 3, a terminal-equipped electric wire 3 with a terminal 2 attached to the tip of an electric wire 1 is automatically inserted into a connector using an insertion robot or the like. The connector housing 6 is gripped by the hand 5 of the connector housing 6 and inserted into each terminal accommodating chamber 7 of the connector housing 6. In this case, each terminal 2 may have to be inserted in various orientations as shown in FIG. 4 to insert each terminal 2 into each terminal receiving chamber 7 of the connector housing 6. Therefore, when inserting the terminal 2 into the terminal housing chamber 7, the terminal 2
It is necessary to change the direction of the object to the required direction.

(Problem to be Solved by the Invention) Conventionally, such a change in the orientation of the terminal 2 was performed on the insertion head side of an automatic terminal insertion device into a connector, which is an insertion robot or the like. Therefore, the structure of the insertion head becomes complicated, the weight becomes heavy, and the inertia increases, making it difficult to position the terminal for insertion.

An object of the present invention is to provide a device for transferring electric wires with terminals to a connector for an automatic terminal insertion device, which can change the orientation of the terminal without providing a rotating means for changing the terminal orientation on the insertion head of the automatic terminal insertion device. It's about doing.

is supported by As the terminal direction changing rotation means 22, for example, an index motor, a pulse motor, a servo motor, etc. are used. The terminal orientation changing rotation means 22 receives an angle command for rotation from a rotation angle command means 24. The terminal orientation changing rotation means 22 is
The electric wire 1 is driven in the horizontal direction along the longitudinal direction of the electric wire 1 together with the second gripping tool 19 by a second horizontal reciprocating means 25 formed of a cylinder. This second horizontal reciprocating means 2
5 is similarly composed of a cylinder main body 26, a piston 27, and a piston rod 28, and a terminal orientation changing rotating means 22 is supported at the tip of the piston rod 28 via a bracket 29. 1st. The second horizontal reciprocating means 15.25 are supported on a common support frame 30. The first and second gripping tools 8 are connected to each other through the support frame 30.
．． 19, a terminal orientation changing rotation means 22, and a first. Second
The horizontal reciprocating means 15.25 is adapted to be raised and lowered by a second elevating means 31. The second elevating means 31 is
Similarly, it is composed of a cylinder main body 32, a piston 33, and a piston rod 34, and a support frame 30 is supported at the tip of the piston rod 34. The second elevating means 31 is supported by a support base 35.

The operation of transferring terminal-equipped electric wires using such a device will be explained. The part of the electric wire 3 with a terminal on the terminal 2 side beyond the part of the electric wire 1 held by the wire gripping tool 36 is vibrated vertically under tension in the previous process for straightening. A conveyor (not shown) moves intermittently in a horizontal position. Second gripping tool 8, 19
When it is brought to a predetermined position opposite to as shown in the figure,
First, the first elevating means 11 is operated to raise the first gripping tool 8, and the barrel side of the terminal 2 is inserted between the opened re-gripping pieces 9. In this state, the re-grasping piece 9 of the first gripping tool 8
grips the barrel portion of the terminal 2 from the left and right directions, and the bending of the terminal 2 and the electric wire 1 in the left and right direction is corrected. Next, the second horizontal reciprocating means 25 is activated, and the second gripping tool 19 opens its re-gripping piece 20 and rotates the terminal orientation changing rotation means 22.
At the same time, it is pushed out to the right in FIG. The re-gripping piece 20 is closed with the tip of the terminal 2 inserted between the re-gripping pieces 20, and the terminal 2 is gripped by the second gripping tool 19.

In this state, the *a gripping tool 36 opens and the second
The elevating means 31 is activated, and each device mounted on the support frame 30 is elevated to a position where it does not hit the wire gripper 36 even if the first elevating means 11 moves horizontally. Next, the re-gripping piece 9 of the first gripping tool 8 opens, and the first horizontal reciprocating means 15
is activated, the first gripping tool 8 is horizontally moved to the right in FIG. 1 together with the first lifting means 11, and the electric wire 1 is supported by the first gripping tool 8. The first horizontal reciprocating means 15 is actuated when the first gripper 8 is away from the terminal 2 and the electric wire 1 is
This is to prevent the first gripping tool 8 from getting in the way when the hand 5 of the automatic terminal insertion device 4, which is an insertion robot or the like, grabs the electric wire 111 at a position near the terminal 2. Next, the terminal direction changing rotation means 22 is activated by a command from the rotation angle command means 24, and the second gripping tool 19
is rotated, thereby rotating the terminal 2 in the desired direction. In this state, the hand 5 of the automatic terminal insertion device M4 into the connector, which is an insertion robot or the like, grasps the electric wire 1 between the first and second gripping tools 3 and 19, and then grips the second gripping tool 19 again. The piece 20 is opened, the second horizontal reciprocating means 25 is operated, and the second gripping tool 19 is moved to the terminal orientation changing rotating means 2.
2 and retreat. In this state, the hand 5 of the automatic terminal insertion device 4 carries the terminal-attached electric wire 3 and inserts it into a predetermined terminal accommodating chamber 7 of the connector housing 6.

(Effects of the Invention) As explained above, in the terminal-attached electric wire delivery device for the terminal automatic insertion device into the connector according to the present invention, the second gripping tool for gripping the terminal is rotationally driven by the terminal orientation changing rotation means. Therefore, the terminal can be set in a predetermined direction with this terminal-attached electric wire delivery device. Therefore, according to the present invention, the insertion head of the automatic terminal insertion device into the connector does not need to be provided with a rotating means for changing the direction of the terminal, the structure of the insertion head can be simplified, and the amount of hanging can be reduced. . Therefore, the inertia of the insertion head can be reduced, and the insertion head can be accurately positioned with respect to the connector housing.
