Description

  The present invention relates to a flat cable peeling method and a flat cable peeling apparatus, and more particularly, to a flat cable that partially peels an insulator of a flat cable to expose the conductors of the flat cable and weld the conductors together. The present invention relates to a peeling method and a flat cable peeling apparatus.

  The flat cable is configured by, for example, a plurality of conductors such as flat conductors arranged in a plane, and an outer periphery of the plurality of conductors covered with an insulator such as resin. The flat cable is flat and has a smaller space occupancy than a normal electric wire having a circular cross section, and is suitable for downsizing. For this reason, for example, it is suitably used for wiring of an electric device or the like mounted on an automobile in which a vehicle space is likely to be limited.

  When wiring a flat cable in an automobile, the wiring may be branched by connecting the flat cables. In this case, the insulator covering the conductor with the intermediate portion of the flat cable is partially peeled to expose the conductor, and then the exposed conductors are welded by resistance welding or the like to perform splicing.

  As a method of partially peeling the insulator of the flat cable, a method using a laser beam or the like is known. For example, Patent Document 1 discloses a method in which a portion where an insulator conductor made of a resin film is irradiated with a laser and the insulator in that portion is melted by the heat of the laser to expose the conductor.

JP 2002-27626 A

  However, when the conventional method of melting the entire target area of the insulator by laser irradiation is performed, there is a risk that the insulator remains undissolved depending on the laser irradiation conditions. If there is an undissolved portion of the insulator in the target area, the insulator covers the conductor surface in the target area, which may result in insufficient welding between the conductors.

  The problem to be solved by the present invention is to provide a flat cable peeling method that can reliably peel off an insulator in an intermediate portion of the flat cable. Another object of the present invention is to provide a flat cable peeling apparatus suitable for a flat cable peeling method.

  In order to solve the above problems, a flat cable peeling method according to the present invention peels off the insulation of a flat cable formed by covering the outer periphery of a plurality of conductors spaced apart from each other and arranged in parallel. Laser cutting is applied to the outer edge portion of the target region, and the blade plate and the flat cable are relatively slid in a state where the blade plate is brought into contact with and biased against the surface of the insulator. The gist is to strip off the inner insulator.

  At this time, it is preferable that a plurality of blade plates are arranged in parallel so as to correspond to the plurality of conductors, and each blade plate is biased by an independent biasing mechanism.

  In this case, the urging mechanism may be a spring or an air cylinder.

  And it is good to make the cutting angle of the said blade plate an obtuse angle.

  Furthermore, it is preferable that the blade plate is disposed on both sides of the front surface and the back surface of the flat cable and is brought into contact with both surfaces of the insulator in pairs.

  On the other hand, the flat cable peeling apparatus according to the present invention includes a holding means for holding a flat cable formed by covering an outer periphery of a plurality of conductors arranged in parallel and spaced apart from each other, and the held flat Laser irradiation means for irradiating the surface of the insulator of the cable with laser light along a pre-designed pattern, a blade plate abutting against the surface of the insulator of the held flat cable, and the blade plate The gist of the invention is to include a peeling mechanism having a biasing mechanism that biases the surface of the insulator and a sliding mechanism that slides the blade plate along the axial direction of the held flat cable.

  Alternatively, a feeding means for feeding a flat cable formed by covering an outer periphery of a plurality of conductors that are spaced apart from each other and arranged in parallel and a surface of the insulator of the sent flat cable are designed in advance. Laser irradiation means for irradiating laser light along a pattern, a blade plate in contact with the surface of the insulator of the flat cable to be sent, and a biasing mechanism for biasing the blade plate against the surface of the insulator The gist is to include a peeling means having

  In these, the laser irradiation means has a pair of laser irradiation portions on both sides of the insulator of the flat cable, and the skinning means is provided in pairs on both sides of the insulator of the flat cable. It is desirable.

  According to the flat cable peeling method according to the present invention, the blade plate and the flat cable are relatively slid in a state where the blade plate is applied to the portion where the insulator is cut by laser irradiation and the blade plate is biased. Therefore, the insulator can be peeled off so that the insulator is not left in the target region by cutting the insulator in the target region by inserting the blade plate into the cut portion of the insulator. And, for example, when a plurality of cuts are formed in the insulator along a pre-designed pattern, it is ensured that all cuts are made without positioning the positions where the blade plate is applied to the cuts. The insulator can be stripped off.

  At this time, if a plurality of blade plates are arranged in parallel corresponding to the plurality of conductors of the flat cable, and each blade plate is urged by an independent urging mechanism, any arbitrary flat plate cable It can cope with peeling of the pattern.

  When the urging mechanism is a spring or an air cylinder, the above-described effect is surely obtained.

  At this time, if the cutting angle of the blade plate is obtuse, the blade plate is inserted into the place where the insulator is cut, and after the insulator in the target area is turned off, the blade plate is exposed on the exposed conductor. Then, when the insulator reaches the non-target region edge of the insulator and does not enter the insulator edge, the insulator is moved up, so that only the target region can be peeled off with high accuracy.

  Furthermore, when the blade plate is disposed on both sides of the front and back surfaces of the flat cable and is brought into contact with both sides of the insulator in pairs, both sides of the insulator can be peeled simultaneously.

  On the other hand, according to the flat cable peeling apparatus according to the present invention, after the laser irradiation is performed on the surface of the flat cable insulator by the laser irradiation means to make a cut, the blade plate is attached to the insulator by the urging mechanism of the peeling means. By sliding the blade plate with the slide mechanism while being pressed against the surface, the blade plate is inserted into the place where the insulation is cut, and the insulation in the target region is turned up. The insulator can be peeled off so that no insulator remains on the surface.

  For example, when the blade plate is slid along the axial direction of the flat cable and a plurality of cuts are formed along the axial direction, the position where the blade plate is applied to each cut forming position in the axial direction. Even if positioning is not performed, the insulator can be surely peeled off at all the incisions by sliding the blade plate.

  In the flat cable peeling apparatus according to the present invention, the same effect as described above can be obtained not only by the structure in which the blade plate is slid by the slide mechanism but also by the structure in which the flat cable is slid by the feeding means for feeding the flat cable.

  In these cases, the laser irradiation means has a pair of laser irradiation portions on both sides of the flat cable insulator, and the peeling means is provided in pairs on both sides of the flat cable insulator. Both sides of the flat cable can be peeled simultaneously.

  Next, an embodiment of the present invention will be described in detail.

  In the flat cable peeling method according to the present invention, as shown in FIG. 1, the outer edge portion of the target region 16 to be peeled off is cut by laser irradiation, and then the flat cable 10 is insulated. The blade plate 18 is brought into contact with the surface of the body 14 and the blade plate 18 and the flat cable 10 are relatively slid to peel off the insulator 14 in the target region 16.

  The flat cable 10 is formed by covering an outer periphery of a plurality of conductors 12 spaced apart from each other and arranged in parallel with an insulator 14. The flat cable 10 may be held in the vicinity of the laser irradiation unit that performs laser irradiation by a holding unit such as a clamp, or may be conveyed by a feeding unit such as a general cable feeding device. When transporting the flat cable 10, for example, the flat cable 10 may be transported continuously at a constant speed or intermittently.

  The laser irradiation is performed by generating a laser by laser irradiation means such as a laser oscillation device. At this time, for example, a movable mirror such as a rotating polygon mirror such as a polygon mirror or a plane mirror such as a galvanometer mirror can be arranged on the irradiation line of the laser beam, and reflected by the movable mirror to scan the laser beam.

  For example, when the flat cable 10 is fixed with a clamp or the like and irradiated with laser, the laser beam can be scanned to form a cut in a window shape at a desired position. Further, when the flat cable 10 is transported, it is preferable to scan with a laser beam in order to form a cut in the window shape.

  A pattern for peeling the flat cable 10 can be designed in advance by CAD or the like. Then, a desired pattern can be formed by reading the designed pattern into a laser oscillation device and outputting it.

  As shown in FIG. 1, the flat cable 10 has a plurality of conductors 12. The same or different cut patterns may be formed in each insulator 14 on the plurality of conductors 12. In these cases, for example, laser light may be emitted (scanned) from one light source, or a plurality of light sources (light source bundles) may be formed, and each insulator on the plurality of conductors 12 from each light source. 14 may be emitted (scanned).

Examples of the laser light source include a CO ₂ laser and YAG. As a material constituting the insulator 14 that covers the conductor 12 of the flat cable 10, PVC, PET, polyolefin, and the like are often used, and because only these resin materials can be efficiently dissolved, A CO ₂ laser is preferred. In addition, conditions necessary for laser irradiation can be determined as appropriate.

  The insulator 14 is cut by the laser irradiation. As shown in FIG. 2A, the blade plate 18 is brought into contact with the surface of the insulator 14 of the flat cable 10 against the cut portion of the insulator 14, and an urging mechanism 20 such as a spring or an air cylinder. The blade plate 18 is biased against the surface of the insulator 14 (here, a spring is shown). Next, the blade plate 18 and the flat cable 10 are slid relative to each other.

  At this time, the flat cable 10 may be fixed and the blade plate 18 may be slid, or the blade plate 18 may be fixed and the flat cable 10 may be slid. The flat cable 10 is arranged straight as shown in the drawing, and the blade plate 18 and the flat cable 10 may be relatively slid along the surface of the insulator 14 of the flat cable 10.

  When the blade plate 18 and the flat cable 10 are slid relative to each other, the blade edge of the urged blade plate 18 falls into the cut groove 22 of the insulator 14 as shown in FIG. If it slides as it is, as shown in FIG.2 (c), it will scoop up the insulator 14 of the object area | region 16, and will begin to cut. By continuously sliding, the insulator 14 in the target region 16 can be peeled off from the flat cable 10 as shown in FIG. Thereafter, as shown in FIG. 2 (e), the blade plate 18 travels on the exposed conductor 12 to reach the edge 14a of the non-target region of the insulator 14, and rides on the edge 14a, Slide on the insulator 14 and move to the next skinning target area.

  The force with which the urging mechanism 20 presses the blade plate 18 can fall on the insulator 14 again after the blade plate 18 falls into the cut groove 22 of the insulator 14 and peels off the insulator 14 in the target region 16. It should be adjusted to the range. If the urging mechanism 20 is a spring, the space for attaching to the blade plate 18 can be reduced. Further, when the urging mechanism 20 is an air cylinder, the force for pressing the blade plate 18 by the urging mechanism 20 can be easily finely adjusted.

  In order to make it easier to ride the blade plate 18 on the insulator 14 without stripping the blade edge of the blade plate 18 into the edge 14a of the non-target region after the insulator 14 is peeled off, the insulator of the flat cable 10 is used. It is preferable to pay attention to the cutting angle when the blade plate 18 is brought into contact with the surface 14. As shown in FIG. 3A, the cutting angle is determined by the clearance angle α formed by the surface of the insulator 14 and the clearance surface 18a of the blade plate 18, and the clearance surface 18a and the rake surface 18b of the blade plate 18. It is the sum θ with the blade angle β to be formed, and it is preferable to make the cutting angle θ an obtuse angle.

  In order to make the cutting angle θ an obtuse angle, for example, as shown in FIG. 3A, the surface processed into a tapered shape is directed in the traveling direction, and the blade plate 18 is contacted with the surface of the insulator 14 at a substantially right angle. As shown in FIG. 3B, the blade plate 18 is inclined in the traveling direction of the blade plate 18 with the surface processed into a tapered shape facing the direction opposite to the traveling direction, and the insulator 14 It is better to contact the surface. Moreover, as shown in FIG.3 (c), the thing of a double blade can be used instead of a single blade. In the case of a double-edged blade, the cutting angle θ can be made obtuse if it is brought into contact with the surface of the insulator 14 at a substantially right angle.

  As shown in FIG. 4, the single-edged blade plate 18 is usually arranged with the surface processed into a tapered shape facing the direction opposite to the traveling direction. In this case, after the insulator 14 is peeled off, the blade plate 18 may be caught on the edge 14a of the non-target region, and the insulator 14 in the non-target region is likely to be damaged. Furthermore, when the cutting angle θ is set to an acute angle, the cutting edge of the blade plate 18 easily enters the non-target region edge 14a after the insulator 14 is peeled off.

  In the step of stripping off the insulator 14, a plurality of blade plates 18 can be arranged in parallel so as to correspond to the plurality of conductors 12, respectively, as shown in FIG. In this case, each blade plate 18 is preferably urged by an independent urging mechanism 20. For example, when the blade plate 18 is urged by a spring or an air cylinder, a spring or an air cylinder may be attached to each blade plate 18. When each blade plate 18 has an independent urging mechanism 20, each blade plate 18 can independently strip the insulator 14, so that when a different cutting pattern is formed on each conductor 12. Can also respond. Accordingly, the plurality of conductors 12 can be peeled simultaneously.

  Moreover, as shown in FIG. 1, the blade board 18 can be arrange | positioned on the both surfaces of the surface and the back surface of the flat cable 10, and it can be made to contact | abut on both surfaces of the insulator 14. In order to arrange the blade plates 18 in pairs on both sides, the flat cable 10 may be arranged straight without forming a curved portion in the flat cable 10. In this case, both surfaces of the insulator 14 can be peeled simultaneously.

  Next, an embodiment of a flat cable peeling apparatus according to the present invention will be described in detail.

  The peeling apparatus 30 shown in FIG. 5 has various means on the base 32, has a clamp 34 that holds the flat cable 10 at the center position, and laser irradiation means that irradiates laser light on both sides of the clamp 34. 36 is arranged, and a stripping means 40 for stripping the insulator 14 of the flat cable 10 is installed downstream of the laser irradiation means 36 so as to sandwich the held flat cable 10.

  In the clamp 34 that holds the flat cable 10, a pair of holding plates 34 a that sandwich the surface of the flat cable 10 are disposed so as to face each other in the horizontal direction. In order to hold the flat cable 10 at two locations, the clamps 34 are arranged at two locations with a distance therebetween.

  The laser irradiating means 36 disposed on both sides of the clamp 34 has laser emitting portions 38 for emitting laser light, and the laser emitting portions 38 are respectively provided on both surfaces of the flat cable 10 disposed between the laser irradiating means 36. They are arranged facing each other so that laser irradiation is possible. The laser irradiation means 36 is provided with a movable mirror such as a galvanometer mirror so that the laser beam can be scanned within a certain range.

  The skin peeling means 40 installed downstream of the laser irradiation means 36 is provided with a plurality of blade plates 18 on both sides of the surface of the flat cable 10, and the blade tips 18 face each other to form a pair. is doing. A biasing mechanism 20 is attached to the blade plate 18 so as to be biased from both sides. As shown in FIG. 6, the urging mechanism 20 includes a rectangular tube-shaped accommodation member 42 that can accommodate the blade plate 18. A plurality of storage chambers 44 for storing a plurality of blade plates 18 are provided inside the storage member 42, and each blade plate 18 is stored one by one in each storage chamber 44. A small opening 46 is formed on the bottom surface of the storage chamber 44 so that the tip of the blade plate 18 protrudes, and a large opening serving as a storage port for storing the blade plate 18 is formed on the top surface of the storage chamber 46. 48 is formed. The inner peripheral surface of the opening 48 on the upper surface is threaded and is closed with a screw 50.

  In each storage chamber 44, the blade plate 18 is stored, and then the spring 52 is stored. Each of the openings 48 serving as an accommodation port is closed with a screw 50, and the spring 52 is compressed by the screw 50. The blade plate 18 is biased by the expansion / contraction force of the spring 52. When the screw 50 is turned, the accommodated spring 52 is pushed and expanded by the screw 50, whereby the urging force can be adjusted. The base end portion 18 a of the blade plate 18 is wider than the tip portion in the reciprocating direction of the blade plate 18, and serves as a stopper that prevents the blade plate 18 from jumping out from the bottom surface of the storage chamber 44. Yes. The plurality of blade plates 18 are arranged in parallel so as to correspond to the positions of the plurality of conductors 12 of the flat cable 10, and each blade plate 18 is independent by an urging mechanism 20 by an independent spring 52. Is energized.

  As shown in FIG. 7, a sliding mechanism 54 is connected to the urging mechanism 20. The slide mechanism 54 includes a slide portion 60 that is integrally formed at the tip of a rod 58 that can be reciprocated by an air cylinder 56, and the biasing mechanism 20 is integrally installed on the slide portion 60. A plurality of blade plates 18 can slide.

  In the peeling apparatus 30 of FIG. 5 having the above-described configuration, the flat cable 10 is sandwiched between the clamps 34 and disposed between the laser irradiation means 36, and then the insulator 14 is irradiated with laser by the laser irradiation means 36 and then cut into the insulator 14. Is formed. Next, in a state where the blade plate 18 of the skin peeling means 40 is abutted from both sides of the flat cable 10 by the urging mechanism 20 and is urged, the blade plate 18 is inserted into the place where the insulator 14 is cut by the slide mechanism 54. Slide. The blade edge of the urged blade plate 18 falls into the cut groove 22 of the insulator 14, and the insulator 14 in the target region 16 is scooped up and cut so that the insulator 14 does not remain in the target region 16. Then, the insulator 14 in the target region 16 is peeled off from the flat cable 10. After that, the blade plate 18 travels on the exposed conductor 12 and reaches the end edge 14a of the non-target region of the insulator 14, and rides on the end edge 14a and slides on the insulator 14 for the next peeling target. Move to the area and peel again.

  Since the blade plate 18 is automatically dropped into the cut groove 22 by the urging force of the urging mechanism 20 when the sliding blade plate 18 comes into the cut groove 22, the insulator 14 is peeled off. On the other hand, it is not necessary to position the blade plate 18 against the blade plate 18.

  The pattern for stripping the flat cable 10 is read out by a laser irradiation means 36 that has been designed in advance by CAD or the like, thereby forming a desired pattern. The insulator 14 is formed with a plurality of cuts along a desired pattern, but each blade plate 18 urged by each independent urging mechanism 20 can be independently expanded and contracted. It is possible to handle peeling of an arbitrary pattern on the entire cable 10. And the insulator 14 can be reliably stripped off about all the cut places, without positioning especially the position which contacts the blade board 18 with respect to the cut place. Therefore, it is possible to easily cope with various complicated patterns.

  Next, a peeling apparatus according to another embodiment will be described. The skinning device 30 shown in FIG. 8 includes a feeding means 62 that feeds one side of the flat cable 10 and a guide roll 66 that supports the other side of the flat cable 10 at the center position on the base 32. Are respectively provided with laser irradiation means 36 for irradiating laser light, and a peeling means 40 for peeling the insulator 14 of the flat cable 10 is provided downstream of the laser irradiation means 36 so as to sandwich the held flat cable 10. Has been.

  The feed means 62 includes a pair of transport rolls 64 that support one side of the flat cable 10, and the transport roll 64 feeds the flat cable 10 while sandwiching it. The other end of the flat cable 10 is supported by the guide roll 66, and the flat cable 10 can be sent in accordance with the conveyance by the conveyance roll 64.

  The laser irradiation means 36 arranged on both sides of the guide roll 66 has a laser emission section 38 for emitting laser light, and the laser emission sections 38 are provided on both sides of the flat cable 10 arranged between the laser irradiation means 36. They are arranged so as to face each other so that laser irradiation is possible. The laser irradiation means 36 is provided with a movable mirror such as a galvanometer mirror so that the laser beam can be scanned within a certain range.

  The skin peeling means 40 installed downstream of the laser irradiation means 36 is provided with a plurality of blade plates 18 on both sides of the surface of the flat cable 10, and the blade tips 18 face each other to form a pair. is doing. A biasing mechanism 20 is attached to the blade plate 18 so as to be biased from both sides. The urging mechanism 20 has the same configuration as the urging mechanism 20 shown in FIG.

  In the peeling apparatus 30 of FIG. 8 having the above configuration, the flat cable 10 is sandwiched and disposed between the laser irradiation means 36 at two locations of the conveyance roll 64 and the guide roll 66 of the feeding means 62, and then the laser irradiation means 36. The insulator 14 of the flat cable 10 is irradiated with laser to form a notch in the insulator 14. Next, when the flat cable 10 is sent to the downstream side by the transport roll 64 in a state in which the blade plate 18 of the skin peeling means 40 is abutted from both sides of the flat cable 10 by the urging mechanism 20 and urged, the flat cable 10 Along with the movement, the blade plate 18 is slid to the place where the cut of the insulator 14 is made. The blade edge of the urged blade plate 18 falls into the cut groove 22 of the insulator 14, and the insulator 14 in the target region 16 is scooped up and cut so that the insulator 14 does not remain in the target region 16. Then, the insulator 14 in the target region 16 is peeled off from the flat cable 10. Thereafter, the blade plate 18 travels on the exposed conductor 12 to reach the edge 14a of the non-target region of the insulator 14, rides on the edge 14a, slides on the insulator 14, and then peels off the next skin. Move to target area and peel again.

  Therefore, as in the case of FIG. 5, the skinning device 30 of FIG. 8 can surely strip the insulator 14 from various complicated patterns without special positioning.

  Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.

  For example, although the urging mechanism 20 uses a spring 52, the same effect can be obtained even when an air cylinder using an air drive system is used. If the urging mechanism 20 is a spring, the space for attaching to the blade plate 18 can be reduced. Further, when the urging mechanism 20 is an air cylinder, the force for pressing the blade plate 18 by the urging mechanism 20 can be easily finely adjusted. The slide mechanism 54 may be motor driven.

  The flat cable skinning method and flat cable skinning apparatus according to the present invention are suitably used for skinning flat cables used for, for example, vehicle parts, electrical / electronic equipment parts, and the like.
