Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a connector housing in which an insertion head is provided with a pair of hands on the left and right, and each of these hands supports an electric wire with a terminal to be inserted. The present invention relates to an automatic terminal insertion device into a connector which automatically inserts and covers the terminal of the electric wire with a terminal into the terminal receiving terminal of the connector.

[Prior Art] For example, in order to automatically manufacture wire harnesses for automobiles, as shown in FIG. 6, a terminal-equipped electric wire 13 with a terminal 2 attached to the tip of an electric wire 1 is inserted into an insertion head in an automatic terminal device such as a robot. The terminal 2 at the tip of the electric wire 3 with a terminal is inserted into a specific terminal accommodating chamber 6 of the connector housing 5 using the terminal insertion guide 7 as a guide. In addition, 8 is a housing support stand which supports the connector housing 5, and 9 is a housing presser shell. In this case, the insertion head is equipped with a pair of hands on the left and right sides of the head body (not shown), and each of these hands supports the electric wire with a terminal to be inserted, and one hand is inserted into the end storage chamber 6 of the connector housing 5. The terminal "lightning"
A type that automatically inserts an A3 sheet is being proposed. Such an insertion head can be used to handle electric wires 3 with terminals, which have terminals 2 attached to both ends of electric wire 1, such as wire harnesses, by grasping both terminal sides with each hand. The workability is good because it can be done easily.

[Problems to be Solved by the Invention] However, in this case, since both hands of the insertion head support the electric wires 3 with terminals, one hand performs the work of inserting the terminals 2 into the connector housing 5. When the terminal 2 supported by the other hand hits the electric wire 1 connected to the terminal 2 that has already been inserted into the connector housing 5 during the approach movement toward the connector housing 5 for insertion, the terminal insertion operation may be interrupted. There was a problem that got in the way.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic terminal insertion device into a connector in which when one hand is performing terminal insertion work, the terminals supported by the other hand do not interfere with the insertion work.

[Means for Solving the Problems] The structure of the present invention for achieving the object mentioned above will be explained with reference to FIGS. 1 to 5 corresponding to the embodiments. Head 15 has a pair of hands on the left and right 19.20
The hands 19 and 20 respectively support the terminal-equipped electric wire 3 to be inserted, and one by one automatically inserts the terminal 2 of the terminal-equipped electric wire 3 into the terminal accommodating chamber 6 of the connector housing 5. In the automatic terminal insertion device, the insertion head 15 has a pair of cylinders 17.18 supported on the left and right sides of the head body 16, and these cylinders 17.18 correspond to respective piston rods 17A.

[Function] When each cylinder 17, 18 is supported by the head body 16 in such a manner that its piston rods 17A, 18A move diagonally downward and back and forth, the hand 20 at the tip of one cylinder 18 performs the work of inserting the terminal 2. While doing so, the hand 19 at the tip of the other cylinder 17 is connected to the electric wire 3 with a terminal.
Since the hand 19 is waiting diagonally upward while holding the
Alternatively, the terminal 2 supported by this can stand by without hitting the connector housing 5 or the electric wire 1 of the terminal-attached electric wire 3 in which the terminal 2 is already inserted into the connector housing 5.

[Embodiment 1] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 5. As shown in the figure, the connector housing 5 into which the terminal 2 is to be inserted is located at each positioning portion 1 of the housing support base 8.
0, respectively, and are respectively locked by the housing presser 9, and are supported in a horizontal line at predetermined intervals (not shown). A terminal insertion guide 7 is positioned in front of a specific terminal accommodating chamber 6 into which the terminal 2 is inserted. The terminal insertion guide 7 is positioned in the XYh directions by an X-direction positioning mechanism 11 for positioning in the X-direction (horizontal direction) and a Y-direction positioning mechanism 12 for positioning in the Y-direction (vertical direction), and the positioning is completed. Then, the back and forth reciprocating mechanism 13 moves the terminal insertion guide 7 into the terminal accommodating chamber 6.
It is designed to be set close to the entrance.

The automatic terminal insertion device 14 made of a robot or the like has an insertion head 15 at its tip, and a pair of cylinders 17 and 18 on the left and right sides of the head body 16 of the insertion head 15 directs the piston rods 17A and 18A diagonally downward. It is supported in a direction that allows it to move back and forth. Each piston rod 17A, 18
Hands 19 and 20 are supported at the tips of A, respectively. Each hand 19.20 has a pair of gripping pieces 21.
22, and a drive section 23.2/l that opens and closes these gripping pieces 21.22. The drive parts 23 and 24 each include a cylinder main body 25, a piston 26 that moves by friction within the cylinder body, a piston rod 27 driven by the piston 26, and a fulcrum 28 by the movement of the screws 1 to 27. It is composed of a pair of dogleg-shaped link arms 29 that open and close at the center, and a grip piece 21 is fixed to the tip of each link arm 29. A bar-shaped movable guide 30.31 is cantilever-supported on each hand 19.20 in a direction parallel to the cylinder 17.18, and this movable guide 30.3
Fixed guides 32 and 33 that regulate the direction of the head body 16 are fixed to the head body 16, and these guides 30.
3, the hands 19 and 20 are moved in parallel without swinging.

Such an automatic terminal insertion device 14 is configured such that each hand 19, 20 grasps the electric wire 1 near each terminal 2 of the electric wire 3 with a terminal, in which the terminal 2 is attached to each end of the electric wire 1, and inserts the electric wire 1 into the connector housing 5. A case will be described in which each terminal 2 is inserted into. The insertion work is performed first by one hand 20, and then by the other hand 19. As described above, the terminal insertion guide 7 is positioned and waiting at the entrance of the terminal accommodating chamber 6 into which the connector housing 5 is to be inserted. Automatic terminal insertion device 14 consisting of a robot, etc.
positions the terminal 2 supported by the hand 20 in the X direction (horizontal direction) and in the Y direction (vertical direction) at the standby position. When such positioning is completed, the cylinder 18 is actuated to project its piston rod 18A diagonally downward as shown in FIG. With this U'' operation, the terminal 2 on the hand 22 side is placed in a position facing the entrance of the terminal accommodating chamber 6 into which the connector housing 5 is to be inserted.

After that, the insertion head 15 is moved horizontally toward the connector housing 5 (Z direction) by the action of the automatic terminal insertion device 14.
The terminal 2 is pushed out by the guiding action of the terminal insertion guide 7.
is inserted into the connector housing 5 and locked as shown in FIG. When the hand 20 approaches the connector housing 5 to insert the terminal 2, the other hand 19 and the terminal 2 supported by it are waiting diagonally upward as shown in FIG. The hand 19 or the terminal 2 supported by the hand 19 can stand by without hitting the connector housing 5 or the electric wire 1 of the terminal-attached electric wire 3 in which the terminal 2 has already been inserted into the connector housing 5. That is, in this case, the positional relationship between one terminal 2 that is being inserted and the other terminal 2 that is waiting is such that the piston rod 18A of the cylinder 18 moves diagonally downward, and the second
As shown in the figure, in addition to the distance l1ilIzD in the Z direction, the distance in the Y direction! Since it is separated by 111YD, the standby level is different from that of the connector housing 6, and it does not get in the way. After the insertion work of the hand 20 is completed, the hand 20 is moved back diagonally upward, and the terminal 2 is inserted in the same way using the other hand 19.

[Effects of the Invention] As explained above, in the device for automatically inserting a terminal into a connector according to the present invention, although a pair of hands are supported on the insertion head via a pair of cylinders, each cylinder was supported by the head body with its piston rod pointing diagonally downward and moving back and forth, so when one hand was inserting the terminal, the other hand was tilting diagonally upward. The insertion work can be performed without the hand being held or the terminal supported by the hand hitting the connector housing or the electric wire of the terminal-equipped electric wire in which the terminal has already been inserted into the connector housing. Therefore, it is possible to perform the insertion work while avoiding failure to insert the terminal due to interference from the waiting hand.

Also, if the cylinder is installed diagonally as in the present invention,
Compared to those that try to achieve the same effect horizontally by lengthening the stroke of the piston rod and making the cylinder more popular, the cylinder can be made smaller and its inertia is smaller.
The insertion head can be easily positioned.
