Description

  The present invention relates to a wiring device that arranges electric wires along a predetermined path on a wiring board, and a wiring pre-processing method that is executed before arranging the electric wires along a predetermined path on the wiring board.

  An electric connection box (that is, an electric junction block) that stores an electric circuit for branching and connecting a plurality of wire harnesses arranged in the vehicle body is mounted on a vehicle such as an automobile.

  In an electrical junction box, a bus bar formed by punching a conductive metal plate is generally used to form an electrical circuit inside the electrical connection box. However, on the wiring board, it can be easily adapted to design changes. A wire in which electric wires are arranged along a predetermined path (that is, a wired wiring board) is also used.

  As a wiring device for wiring to a wiring board, an electric wire is sent out from a head that moves on the wiring board along a wiring groove of the wiring board that defines a wiring path, and a predetermined portion of the sent electric wire (particularly, In addition, it is known that a bent portion or a terminal portion, which is easily lifted from the wiring board, is pushed into the wiring groove by using a pin member provided so as to be able to protrude and retract toward the wiring board on the head. (For example, refer to Patent Document 1).

  In this wiring apparatus, the electric wires are inclined with respect to the wiring board (more specifically, the bottom surface of the wiring groove) in order to easily determine the wiring direction of the electric wires after being sent out from the head outlet. In the state, it is sent out from the outlet of the head. According to this type of wiring device, compared to the conventional wiring device that sends out the electric wire from the head outlet in a state perpendicular to the wiring plate, the electric wire to the wiring groove at the start of wiring Easy to enter.

  In particular, this wiring device adopts a configuration in which the wire is sent out from the head in a state where the electric wire is inclined with respect to the bottom surface of the wiring groove. Therefore, before starting the wiring, the wiring plate end face (for example, a rectangular wiring board, Originally, it is desirable if it does not have a swivelable head (ie, a rotatable head) that can change the wire feeding direction in accordance with the position of the wire entrance of the wiring groove on any one of the four surfaces forming the contour. Can't demonstrate their ability.

  In addition, this type of wiring apparatus usually requires an XY stage on which a wiring board is placed and moved during wiring, but in addition to the movable mechanism such as the XY stage, a further movable mechanism such as the above-described swivel head. If it is provided, it becomes difficult to ensure mechanical accuracy, which may cause a wiring failure. In addition, it goes without saying that the cost of manufacturing the wiring device increases as the swivelable head is provided.

  By the way, in general, when the electric wire used in the wiring apparatus is, for example, a coated electric wire made of a relatively hard single wire or a relatively soft enameled wire, an electric wire protruding from the head while being inclined is used. If the tip is bent and has a wrinkle, the direction of the wire is not accurately determined simply by inclining the wire, and there is a high possibility of causing poor wiring.

  Details of the wiring apparatus 1 configured as described above will be described below.

  As shown in FIG. 1 and FIG. 2, the wiring device 1 is roughly configured by a base 2, the above-described stage 13, the above-described head 4, and an electric wire supply unit 5 that supplies electric wires 6 to the head 4. Has been.

Moves in the horizontal direction (XY axis direction) in combination with a second linear motion device 12 orthogonal to the first linear motion device 11 (the extension direction of the second linear motion device is hereinafter defined as the Y-axis direction). It is possible. The wiring board 31 (see FIG. 7) is horizontally placed on the upper surface 13a of the upper plate of the stage 13 and is held by a holding mechanism (not shown).

  As shown in FIG. 1, the head 4 is fixed to a frame 14 assembled to the base 2 and is disposed above the stage 13. An electric wire supply unit 5 that supplies the electric wires 6 to the head 4 is disposed at the upper end of the head 4.

  The electric wire supply unit 5 is provided with a plurality of pulleys 16. An electric wire 6 wound around a reel (not shown) is pulled out from the reel, suspended between a plurality of pulleys 16 to correct twisting, etc., and substantially vertically downward from the electric wire supply unit 5 toward the head 4. Sent out.

  As shown in FIG. 1 and FIG. 4, the head 4 is provided with an insertion hole 18 at the center thereof through which the electric wire 6 penetrating in the vertical direction and inserted from the electric wire supply unit 5 is inserted. The electric wire 6 sent out substantially vertically downward from the electric wire supply unit 5 is inserted into the insertion hole 18 from the upper opening of the insertion hole 18, and then vertically from the outlet 19 of the insertion hole 18 in the lower surface 4 a of the head 4. Sent out.

  Further, referring to FIG. 5, the head 4 is provided with a plurality of pin members 20 for pressing the electric wire 6 delivered from the delivery port 19 against the wiring board 31 (see FIG. 7). Each pin member 20 extends in the vertical direction inside the head 4 and is accommodated in an accommodation hole 21 that opens on the lower surface 4a of the head 4, and the base end portion 20b is pressed against the cylinder 22 via a link mechanism. As a result, the tip 20 a protrudes vertically downward from the opening of the accommodation hole 21 in the lower surface 4 a of the head 4.

  Further, referring to FIG. 6, the head 4 is provided with a pair of blades 23 for cutting the electric wire 6 in the vicinity of the outlet 19. The pair of blades 23 are respectively housed in a pair of housing grooves 24 extending horizontally from the insertion hole 18 symmetrically with respect to the central axis of the insertion hole 18. The pair of blades 23 are configured such that the sharp end portion 23a protrudes from the receiving groove 24 into the insertion hole 18 when the base end portion 23b is pressed by a cylinder (not shown) via the link mechanism. The electric wire 6 is cut by being sandwiched between both end portions 23 a protruding into the insertion hole 18.

  As shown in FIG. 7, a predetermined plurality of wiring paths are provided on the wiring board 31 on which the electric wires 6 are wired, and side walls 32 are formed continuously or intermittently on both sides along each wiring path. It is erected. In other words, these side walls 32 provide wiring grooves that form a wiring path. That is, the electric wire 6 is inserted into a wiring groove formed between a pair of side walls 32 facing each other. The wiring board 31 is provided with a plurality of wire entrances 32a for wiring grooves that enter first when the electric wires 6 are fitted into the wiring grooves. Other examples of the wiring board include those disclosed in Japanese Patent Application Laid-Open No. 2001-320817.

  Here, not only the wiring board 31 shown in FIG. 7, but generally, most of the wiring paths in the wiring board are set parallel to the X axis or the Y axis. Therefore, in the present embodiment, the plurality of pin members 20 are arranged around the insertion hole 18 at two locations that sandwich the insertion hole 18 along the X axis and at two locations that sandwich the insertion hole 18 along the Y axis. It is installed.

  Next, with reference to FIG. 8, the wiring method of the electric wire 6 to the wiring board 31 using the wiring apparatus 1 comprised as mentioned above is demonstrated.

  The stage 13 holding the wiring board 31 moves so that the head 4 moves on the wiring board 31 along the wiring path.

  The electric wire 6 is fed vertically from the feed port 19 of the insertion hole 18 of the head 4 extending in the vertical direction to the wiring board 31 and is inserted between the side walls 32 of the wiring board 31 that defines the wiring path. The wire 4 comes into contact with the bottom plate 33 and bends, and flows along the relative movement direction A of the head 4 toward the rear side of the delivery port 19 with the relative movement of the head 4.

  Then, the pin member 20 disposed on the rear side of the delivery port 19 as viewed in the relative movement direction A of the head 4 protrudes from the head 4 toward the wiring board 31, and the pin member 20 is relative to the head 4. Along with the movement, the electric wire 6 is continuously urged to the bottom plate 33 of the wiring board 31 by the distal end portion 20a. Thereby, the electric wire 6 is wired to the wiring path of the wiring board 31 without floating from the bottom plate 33.

  Next, with reference to FIG. 9A, FIG. 9B, and FIG. 9C, the wire end folding performed before the wiring to the wiring board 31 described in FIG. 8 is started. The operation of the bending mechanism 17 will be described.

  First, in the bending preparation step shown in FIG. 9A, the stage 13 moves so that the wire tip bending mechanism 17 is positioned near the tip of the wire 6 protruding downward from the outlet 19 of the head 4. . Then, in the first bending step shown in FIG. 9B, the stage 13 further moves to the left in the figure, and the movement of the stage 13 causes the plurality of first tapered surfaces 17Aa of the first bending member 17A to move. One of them comes into contact with the tip of the electric wire 6 and bends the tip of the electric wire 6 at a gentle angle larger than a right angle. At this time, the second taper surface 17Ba of the second bending member 17B parallel to the first taper surface 17Aa also abuts on the distal end portion of the electric wire 6. This abutment also serves as a guide for bending the distal end portion of the electric wire 6. ing. In the steps shown in FIGS. 9A and 9B, the second bending member 17B is in the lower position. Then, in the second bending step shown in FIG. 9C after the first bending step, the flat surface 17Bb moves the tip of the electric wire 6 over the head 4 by moving the second bending member 17B upward. The main body 4A is pressed against the lower surface 4a and bent at a substantially right angle. Thereafter, after the second bending member 17B moves downward, the stage 13 further moves to the left side in the drawing, and the electric wire formed by bending the tip end portion of the electric wire 6 as shown in FIG. 9C. The leading end portion of the electric wire 6 is guided from the corner portion 6 so as to enter the electric wire entrance 32 a (see FIG. 7) at the end portion of the wiring board 31. The subsequent steps are as described with reference to FIG.

  As described above, according to the wiring apparatus 1, the wire tip bending mechanism 17 is provided on the stage 13, and the tip of the wire 6 protruding downward from the outlet 19 of the head 4 before starting the wiring. The stage 13 moves relative to the head 4 so that the wire tip bending mechanism 17 comes into contact with the portion, and the wire tip bending mechanism 17 presses the tip of the wire 6 against the lower surface 4a of the main body 4A of the head 4. Since the electric wire 6 used in the wiring apparatus 1 is bent, the electric wire 6 protruding from the head 4 is easily deformed plastically, such as a covered electric wire having a relatively hard core wire, a relatively soft enameled wire, or the like. Even if the leading end of the wire is bent and bent, the direction of the leading end of the electric wire 6 can be determined reliably. Therefore, according to the wiring device 1, it is easy to enter the electric wire 6 at the start of wiring into the electric wire entrance 32 a of the wiring groove that forms a predetermined wiring path of the wiring board 31. Therefore, according to the wiring apparatus 1, wiring defects can be effectively prevented. Therefore, since the yield in manufacturing the wiring board can be improved, resource saving can be achieved.

  Moreover, according to the wiring apparatus 1, since the electric wire front end bending mechanism 17 bends the front-end | tip part of the electric wire 6 at substantially right angle, the approach of the electric wire 6 at the time of the wiring start to the electric wire entrance 32a of the wiring board 31 is carried out. It can be made easier.

  Moreover, according to the wiring apparatus 1, when the electric wire front end bending mechanism 17 starts contact with the front end portion of the electric wire 6, the first bending member 17A that first bends the front end portion of the electric wire 6 at an angle larger than a right angle. And the second bending member 17B that bends the distal end portion of the electric wire 6 at a substantially right angle after the distal end portion of the electric wire 6 is bent by the first bending member 17A. Even if is attached, the direction of the tip of the electric wire 6 can be determined more reliably.

  Further, in the wiring device 1, a plurality of first tapered surfaces 17Aa are formed at the upper end of the rod-shaped main body of the first bending member 17A, and the second bending movement is vertically movable in the longitudinal direction of the main body of the first bending member 17A. A plurality of second taper surfaces 17Ba provided in parallel with the plurality of first taper surfaces 17Aa at the upper end of the frame-shaped main body of the bending member 17B, and a head continuous with the second taper surfaces 17Ba. When the second bending member 17B is in the lower position, the tip end portion of the electric wire 6 is bent at an angle larger than a right angle when the second bending member 17B is in the lower position. The first taper surface 17Aa and the second taper surface 17Ba abut against the tip of the electric wire 6, and then the second bending member 17B moves upward so that the flat surface 17Bb moves the tip of the electric wire 6 to the main body of the head 4. Lower surface 4a of 4A Pressed bent substantially at a right angle. Therefore, in the wiring device 1, depending on the direction in which the wire entrance 32a of the wiring groove of the wiring board 31 is directed, any one of the plurality of first tapered surfaces 17Aa and the corresponding surface are parallel to each other. Since the stage 13 has only to move relative to the head 4 so that the tip of the electric wire 6 is pressed on any one of the provided second taper surfaces 17Ba, the wiring device 1 can turn. There is no need to provide a simple head. Therefore, according to the wiring device 1, since it is not necessary to provide a head that can be turned, it is easy to ensure mechanical accuracy, and the cost for manufacturing the wiring device 1 can be reduced.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimension, numerical value, form, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  For example, the wiring device 1 described above has a configuration in which the head 4 is fixed and the stage 13 is moved in the horizontal direction (XY axis direction), but the stage 13 is fixed and the head 4 is moved in the horizontal direction ( It may be configured to move in the (XY axis direction). Therefore, the head 4 and the stage 13 may be configured to move relative to each other.

  Moreover, in the wiring apparatus 1 mentioned above, the electric wire front end bending mechanism 17 is the upper surface 13a of the stage 13 in which the wiring board 31 (refer FIG. 7) is mounted so that FIG. 1-3 may show clearly, for example. Although it is attached to the end of a parallel lower plate different from the upper plate of the stage 13 it has, it is not limited to this form, and is attached to the end of the upper plate or other parts of the stage 13 There may be.

  The wire tip bending mechanism 17 may be a mechanism provided separately from the stage 13. When the electric wire tip bending mechanism 17 is provided separately from the stage 13 in this way, the electric wire tip bending mechanism 17 is arranged on the base 2 in the same manner as the stage 13 in the first linear motion device 11 and the second linear motion. A form that can be moved in the horizontal direction (XY axis direction) by a combination of the devices 12 or a form that can be moved in the horizontal direction (XY axis direction) by a separate linear motion device may be adopted. Further, for example, the wire tip bending mechanism 17 may be fixed without being configured to be movable in the horizontal direction (XY axis direction) and the head 4 may be moved in the horizontal direction (XY axis direction). . Accordingly, the head 4 and the wire tip bending mechanism 17 may be configured to move relative to each other.
