Abstract

PROBLEM TO BE SOLVED: To enable mask parts so be cut with no remaining part, even if the mask parts have deviated parts by providing a pair of cutting blades to sandwich a flat-type wiring body, one on the upper side and the other on the under side, and by independently moving each blade to match with the position of the masks to be cut. SOLUTION: When a flat-type wiring body 50 having mask parts 60 to be cut is brought between an upper support base 11 and an under support base 12, the upper surface base 11 is descended and the adhesive part of the flat-type wiring body 50 is caught and cramped by pats 13. After cramped, absorption pads 23 come into contact with the mask parts 60, suck and absorb them. Then an upper absorption arm 21 and an under absorption arm 22 turn by 90 deg., and the mask parts 60 are opened and held vertically with respect to the flat-type wire 50. A cutting mechanism 30 moves back the sheet and cuts the mask parts 60. At this time, even if the mask parts 60 are shifted vertically, upper and under cutting blades 41 and 42 separately mounted on an LM guide move independently, so that the mask parts 60 can be cut with no part remained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for exposing an end conductor of a flat-type wiring body in which a conductor is laminated with an insulating member, which is used as a flat-type electric wiring body used in automobiles and the like.

[0002]

2. Description of the Related Art As a wiring body for electrical parts such as automobiles,
A conductor is sandwiched between insulating members in a sandwich shape, wiring is laminated flat to save wiring occupied space, and a flat wiring body obtained by attaching a connector to the end is used. The insulating member is made of a rigid film mainly composed of polyethylene terephthalate, and its shape is different for each vehicle type in order to improve work efficiency, assemble stability and assemble simplicity when assembling automobiles. In this case, a wiring pattern is prepared and has a complicated shape.

[0003] The flat wiring body before the connector is attached is
It is obtained by sandwiching a flat conductor in a sandwich shape between insulating members coated with an adhesive. However, in order to easily expose the end conductors in the connector mounting process, the conductors must be sandwiched in advance from above and below with a mask film to which no adhesive has been applied, and then insulated from above. The mask film and the conductor are sandwiched between the members. Accordingly, since the mask film adheres to the upper and lower insulating members instead of the conductors, the end conductors are not adhered to the upper and lower insulating members, as shown in FIG.
No. 2 is in a state of being simply sandwiched between the mask films 61. Here, the dotted line indicates a flat conductor in the insulating member.

In order to attach a connector to the end of the obtained flat wiring body, it is necessary to remove the insulating member and the mask film at the end, that is, the mask portion 60, to expose only the conductor. Therefore, in order to remove the mask portion 60 at the end of the wiring body, a portion other than the end of the wiring body is grasped by a clamp mechanism, and the mask portion 60 is attached to the bonding portion 51 by the opening mechanism as shown in FIG. Open and fix it so that it is almost perpendicular to it.

Next, as shown in FIG. 8, while keeping the mask portion 60 at the end substantially perpendicular to the bonding portion 51, the mask portion 6 is provided by the cutting blade 40 provided in the cutting mechanism.
The cutting blade 40 moves so that 0 comes into contact, and cuts from the base of the mask portion.

[0006]

When the mask portion of the flat wiring body, that is, the insulating member and the mask film are cut, depending on the supply state of the mask film, the upper and lower insulating members are opened as shown in FIG. A gap may occur. In other words, a mask film is sandwiched between the insulating member and the conductor in order to prevent the adhesive of the insulating member from adhering to the conductor at the end. Depending on the arrangement of the sandwiched mask film, the mask film is attached to the upper and lower insulating members. The position of the attached mask film is shifted vertically, and as a result, the root portion where the mask portion is bent almost vertically at the time of opening, that is, the boundary between the bonding portion 51 and the mask portion 60 is shifted by the upper and lower insulating members. May be.

With the upper and lower mask films displaced, the mask portion is bent almost vertically by the opening mechanism, and the insulating member and the mask film are cut by the cutting mechanism. The cutting blade provided in the cutting mechanism is fixed. Therefore, an uncut portion 61 as shown in FIG. 9B occurs.

[0008] The connector used for the flat wiring body is sealed to prevent water or the like from entering the inside.
However, in the step of cutting the insulating member and the mask film at the end of the wiring body, if uncut portions or the like are generated by 0.5 mm or more, the end including the exposed conductor cannot be completely accommodated in the connector, and the connector has a waterproof property. Problems may occur.

An object of the present invention is to solve this problem, and to provide an end conductor exposing apparatus which can cut a mask portion without leaving an uncut portion even when an insulating member and a mask film, that is, a mask portion is displaced. It is an object.

[0010]

That is, in order to solve the above-mentioned problems, the present invention is to provide a conductor patterned in a predetermined shape, and sandwiching the conductor with an insulating member at an end portion thereof through a mask film. In order to expose the conductor at the end of the flat-type wiring body sandwiched between the flat-type wiring body, a clamp mechanism for gripping the flat-type wiring body, and the upper and lower mask portions made of an insulating member and a mask film are substantially perpendicular to the flat-type wiring body. It consists of an opening mechanism that opens so as to make it open, and a cutting mechanism that cuts the opened mask part from the root. The cutting blades provided in the cutting mechanism are separated into upper and lower parts so as to sandwich the flat wiring body as a pair of two blades. And the upper and lower portions can be independently moved in accordance with the position of the mask portion to be removed.

Further, the cut blade is provided with a V-shaped notch immediately before the mask portion to be removed comes into contact with the blade of the cut blade, and the entire V-shaped notch has a predetermined angle. It is characterized by doing.

[0012]

According to the end conductor exposing device of the present invention, since the upper and lower cutting blades provided in the cutting mechanism are independently movable, the cutting blade is bent almost perpendicularly to the insulating member and the mask film. Even when the boundary portion, that is, the boundary between the adhesive portion and the mask portion is vertically displaced, the uncut portion of the mask portion to be removed can be eliminated. Furthermore, by providing a V-shaped notch in the cutting blade, even when the position of the mask portion is shifted from the position of the blade of the cutting blade, the mask portion can be positioned at the end of the V-shaped notch. It is possible to cut while moving the cutting blade, which is in contact with the portion and is provided so that the upper and lower portions can be independently moved, so that the position of the mask portion matches the position of the blade of the cutting blade. Become.

FIG. 1 is a part of a side view of an end conductor exposing device according to the present invention. In FIG. 1, 10 is an upper support 1
1, a clamp mechanism 10 comprising a lower support base 12 for gripping a supplied flat wiring body 50, and a pad 13 for gripping the flat wiring body 50 is provided. Before the flat-type wiring body 50 is supplied, the upper and lower supports are fixed at predetermined intervals so that the flat-type wiring body 50 is supplied. When the flat wiring body 50 comes into contact with the pad 13, the upper support is stopped, and the flat wiring body 50 is gripped.

Here, the flat wiring body 50 includes a thin flat conductor sandwiched between upper and lower sandwiches by an insulating member, and an adhesive portion 51 attached by an adhesive member, and an adhesive member attached to the conductor for attaching a connector. Is formed by a mask portion 60 sandwiched by an insulating member via a mask film so that the adhesive portion 51 is not adhered. The adhesive portion 51 is gripped by the clamp mechanism 10.

The upper and lower supports are provided with an upper suction arm 21 and a lower suction arm 22 constituting the opening mechanism 20, and an upper blade support 31 and a lower blade support 32 constituting the cutting mechanism 30, respectively. As the upper support 11 is lowered, the upper suction arm 21 and the upper blade support 31 are also lowered.

An opening mechanism 20 includes an upper suction arm 21 and a lower suction arm 22. The portion of the tip of the upper and lower suction arms that comes into contact with the flat wiring body 50 is provided with a suction pad 23 that generates a suction force by operating a suction device (not shown) in the opening mechanism.
The mask portion 60 of the flat wiring body 50 can be suction-adsorbed. The upper and lower suction arms can be rotated by 90 degrees. After the mask portion is sucked by the suction pad 23, the mask portion 60 is opened and held so as to be perpendicular to the flat wiring body 50.

Reference numeral 30 denotes a mask portion 6 of the flat wiring body 50.
0 is a cutting mechanism 30 for cutting. The cutting mechanism 30 includes a cutting blade 40, an upper blade support 31 and a lower support 32, and the upper blade support 31 is
The lower blade support portion 32 is attached to the lower support base 12, and the upper and lower support portions support the cutting blade 40.

The upper and lower support portions and the cutting blade are connected by an LM guide so that they can move independently in one direction only in one direction, and the cutting blade is connected to the boundary between the mask portion 60 and the bonding portion 51. It is movable perpendicular to the line.

Further, before the flat-type wiring body 50 is supplied, the entire cutting mechanism is provided with the flat-type wiring body 5.
When the mask portion 60 is cut, the mask portion 60 is moved from the back side to the near side to cut the mask portion 60.

Numeral 40 designates a cutting blade 40 for cutting the mask portion 60 of the flat wiring body 50, which is composed of an upper cutting blade plate 41 and a lower cutting blade plate 42. As shown in FIG. 4, the upper and lower cutting blade plate is provided with a V-shaped notch 43 and a mask part guiding groove 44 for guiding the mask part 60 to be removed to the blade 45. The V-shaped notch 43 has a V-shaped notch formed in the cutting blade plate, and the entire V-shaped notch is provided on the upper cutting blade plate 41 with the V-shaped notch facing upward, and the lower cutting blade being cut. The V-shaped cutout provided in the plate 42 is bent outward at a predetermined angle downward.

Therefore, the position of the mask portion 60 opened so as to be perpendicular to the flat-type wiring body 50 and the position of the blade 45 are shifted in the horizontal direction when the flat-type wiring body 50 is supplied. Even when the mask portion 60 abuts on the end of the V-shaped notch portion and the cutting blade plate moves in the direction in which the mask portion exists, the blade located at the base of the V-shaped notch portion is moved. The mask part 60 can be guided to the position of 45.

In addition, the V-shaped cutout portion is provided to be opened to the outside in the vertical direction caused by the warp or the like of the flat wiring body 50, so that the mask portion shifted in the vertical direction is V-shaped. The mask portion 60 can be guided to the position of the blade 45 by contacting the end of the mold notch.

Since the cutting blade plate is attached to the horizontally movable LM guide, the cutting blade plate can follow the position of the mask unit 60 without applying excessive force to the mask unit 60. In addition, since the LM guide is provided independently of the upper and lower cutting blade plates, even if the vertically opened mask portion 60 is vertically displaced, it can independently follow the displacement.

The mask portion guiding groove 44 is for guiding the mask portion 60 positioned at the position of the blade 45 by the V-shaped notch 43 to the blade 45 finally.

Next, the process of removing the mask portion will be described. First, as shown in FIG. 1, a flat-type wiring body 50 having a mask portion 60 to be removed at the tip is supplied between an upper support 11 and a lower support 12 maintained at a predetermined interval.
At this time, the cutting mechanism 30 that cuts the mask unit 60 is located at the back of the drawing. Flat type wiring body 5
When 0 is supplied, the upper support 11 descends as shown in FIG. 2, and the bonding portion 51 of the flat-type wiring body 50 is sandwiched by the pads 13 provided on the support, and the flat-type wiring 5
0 is clamped.

After the clamping, the suction pad 23 attached to the suction arm is in contact with the mask portion 60,
The mask unit 60 is sucked and sucked by a suction force from a suction machine (not shown).

After sucking the mask portion, the upper suction arm 21
The lower suction arm 22 rotates 90 degrees, and the mask unit 60
3 is opened and held perpendicular to the bonding portion 51 as shown in FIG. Next, in order to cut the mask part 60,
The cutting mechanism 30 located at the back of the paper moves to the front of the paper, and
The notch 43 abuts and the mask 60 is guided to the blade 45 as shown in FIG.
Is cut by At this time, even if the mask part 60 is vertically displaced, the upper and lower cutting blade plates independently attached to the LM guide move separately, so that the mask part 6
Cutting can be performed without generating uncut portions such as 0.

The embodiment of the present invention has been described above.
The present invention is not limited to this, and various changes can be made. In the present invention, the angle at which the mask portion is opened is set to 90 degrees, but any opening holding angle can be taken by devising the shape of the cutting blade. As means for moving the cutting blade plate in the horizontal direction with respect to the flat wiring body,
Although the LM guide is used as an example, the member is not particularly limited as long as it is a member that can move in one direction. Further, the size of the V-shaped notch provided on the cutting blade plate is set so that the mask can be brought into contact with the end of the V-shaped notch when the mask is supplied and the cutting mechanism moves. It may be provided over the entire cutting blade plate. The angle of the entire V-shaped notch may be set so that the V-shaped notch does not come into contact with the support at the time of clamping. . In addition, although the V-shaped notch portion is used to position the mask portion and the blade, a control device for positioning the position may be separately provided. In the embodiment, the cutting blade moves as a moving means for cutting the mask portion, but it goes without saying that the support table side may move.

[0030]

As described above, in the state where the cutting blade is fixed, when the upper and lower mask portions are displaced, the conventional mask film removing device cannot cope with the dislocation and uncut portions are generated. In comparison to the above, the cutting blade plate is made up and down independently movable, so even if the mask part is displaced up and down, the cutting blade plate moves up and down separately, and the upper and lower cutting blade plates contact the upper and lower mask parts and cut. Is performed, there is no uncut portion, and the mask portion can be removed cleanly.

Further, since the V-shaped notch is provided in the cut blade plate and the V-shaped notch is provided to be opened outward by the upper and lower cut blade plates, the mask for removing the flat-type wiring body is required. Even if the part is displaced from the position of the blade at the time of feeding, the cutting blade plate moves by the mask part abutting on the end of the V-shaped notch,
Cutting can be performed while the mask portion and the blade are positioned. Therefore, at the time of supply, it is not necessary to perform accurate positioning of the flat wiring body.
