Moreover, the electric wire pulled out from the head part is pressed by the pressing pin at an appropriate timing, and is pushed into the wiring board side to be wired.

JP-A-10-224951

  However, the wiring device is configured to push the electric wire drawn from the head portion into the back by a pressing pin at an appropriate position while being guided by a guide roller.

  For this reason, it is necessary to rotate the whole head part suitably according to the bending condition of a wiring line so that a guide roller and a press pin may be located in the back side with respect to the wiring direction of an electric wire. Therefore, a mechanism for rotating the entire head portion is required, which leads to an increase in the size of the wiring device.

  Accordingly, an object of the present invention is to reduce the size of the wiring device.

  In order to solve the above-described problem, the present invention provides a wiring device for wiring an electric wire with respect to a workpiece to be wired, the head portion guiding the electric wire toward the workpiece, and the workpiece Moving means for moving at least one of the workpiece and the head portion so that the head portion relatively moves, and the electric wire can be pushed out toward the wiring surface of the workpiece on the head portion. An electric wire pushing means is provided.

  In this case, the wire pushing means pushes out the wire with a push amount corresponding to the relative movement amount of the work and the head portion so that the wire is pressed against the wiring surface of the work. It is preferable to enable operation in the operation mode.

  The wire pushing means may be switched to a second operation mode in which the wire pushing means pushes out the wire with a pushing amount smaller than a relative movement amount between the work and the head portion.

  Further, the wire pushing means includes a pair of push rollers that sandwich the wire on the base end side of the head portion, and a rotation drive means that pushes the wire by rotating at least one of the pair of push rollers. A pinching force adjusting means that adjustably applies a force for pinching the electric wire to the pair of extrusion rollers, and the pinching force of the electric wire by the pinching force adjusting means is the first pinching force. It may be smaller in the second operation mode than in the operation mode.

  Moreover, it is good to be able to operate | move also in the 3rd operation mode in which the said head part moves relatively so that the wiring path | route with respect to the said workpiece | work may be turned back, extruding the said electric wire from the said head part.

  According to the wiring apparatus of the present invention, the wiring device includes a head unit that guides the electric wire toward the work, and a moving unit that relatively moves the head unit and the work, and the electric wire is arranged on the wiring surface of the work on the head unit. Since the electric wire push-out means that can be pushed toward the wire is provided, the wire can be wired while being pushed out from the head portion toward the wiring surface of the workpiece. Therefore, unlike the prior art, a guide roller for guiding the drawn electric wire and a pressing pin for pushing the electric wire become unnecessary, and the wiring device can be downsized.

  Also, by operating in the first operation mode for extruding the electric wire with an extruding amount corresponding to the relative movement amount of the work and the head portion so that the electric wire is pressed against the wiring surface of the work. Thus, the wiring can be performed in a state where the electric wire is in contact with the wiring surface more reliably.

  Furthermore, at an appropriate timing, by operating in the second operation mode for extruding the electric wire with an extrusion amount smaller than the relative movement amount between the workpiece and the head portion, tension is applied to the electric wire, It is possible to prevent curling habits.

  Further, when the pinching force of the electric wire by the pinching force adjusting means is made smaller in the second operation mode than in the first operation mode, the electric wire is moved between the pair of rollers in the second operation mode. Can slip out moderately. Therefore, an appropriate tension can be applied to the electric wire.

  Furthermore, while pushing out the electric wire from the head portion, the electric wire is pressed against the workpiece more reliably by operating in the third operation mode in which the head portion moves relative to return the wiring path to the workpiece. be able to.

  As shown in FIGS. 1 and 4, the head unit 20 includes a nozzle unit 22 for inserting and guiding the electric wire 110. In addition, the head unit 20 has a configuration in which a wire pushing mechanism 30 is provided as a wire pushing means for pushing the wire 110 toward the wiring surface 101 of the workpiece 100.

  In the present embodiment, two support pieces 16 and 17 are extended and fixed to a fixed piece 15 fixed to the support column portion 14 side, and a nozzle portion 22 is attached and fixed to the support piece 16 on one side thereof. Yes. The nozzle portion 22 has an electric wire guide hole 22h through which the electric wire 110 can be inserted. The axial direction of the electric wire guide hole 22h is kept substantially perpendicular to the wiring surface 101 of the workpiece 100, and the electric wire guide hole 22h. The wire lead-out side (lower side) of the wire is fixed to the fixing piece 15 in such a posture that the opening faces the wiring surface 101. In addition, the base end side guide nozzle part 22B which guides the electric wire 110 is also provided above the pair of extrusion rollers 32a and 32b described later.

  The wire pushing mechanism 30 includes a pair of push rollers 32a and 32b, a roller rotation drive unit 34 as a rotation drive means for rotating the push rollers 32a and 32b, and a pair of push rollers 32a and 32b.

  The electric wire 110 is sandwiched between the pair of extruding rollers 32a and 32b at the base end side of the head portion 20, in this case, in the vicinity of the opening on the electric wire introduction side (upper side) of the electric wire guide hole 22h. The pair 34 rotates the pair of extrusion rollers 32a and 32b. Accordingly, the electric wire 110 is pushed out toward the wiring surface 101 of the workpiece 100. At this time, the force with which the pair of extrusion rollers 32 a and 32 b pinch the electric wire 110 is adjusted according to the pressing force by the pressure cylinder 36.

  More specifically, a fixed bearing bracket 16a is attached and fixed to the support piece 16 on one side, and an extrusion roller 32a on one side is rotatably supported on the fixed bearing bracket 16a.

  Further, a roller rotation driving unit 34 constituted by a rotation driving means such as a servo motor is attached to the other support piece 17.

  FIG. 5 is a block diagram showing the wiring device 10. As shown in the figure, the wiring device 10 is configured by a general microcomputer including a CPU, a ROM, a RAM, and the like, and includes a control unit 60 that controls a wiring operation described later according to a software program stored in advance. I have.

  In particular, the control unit 60 controls the operation of the XY robot 40 so that the electric wire 110 is wired according to a predetermined wiring pattern registered in advance, and relatively moves the head unit 20 and the workpiece 100. . Further, the control unit 60 controls the rotational speed of the roller rotation driving unit 34 of the wire pushing mechanism 30 so that the wire 110 is pushed out according to the movement amount of the workpiece 100 and the head unit 20. Further, the control unit 60 is connected to an electropneumatic regulator 37 a and a pressure sensor 37 b incorporated in the pressure cylinder 36. Then, the control unit 60 feedback-controls the air pressure by the electropneumatic regulator 37a based on the detection signal of the pressure sensor 37b, so that the urging force by the pressure cylinder 36, that is, the pinching of the electric wire 110 by the pair of push rollers 32a and 32b. Adjust the force. For example, as will be described later, in the second operation mode than in the first operation mode, adjustment is made so that the pinching force of the electric wire 110 is reduced, or according to the rotational speed of the roller rotation drive unit 34, etc. Then, the clamping force of the electric wire 110 is adjusted.

  The wiring operation in the wiring apparatus 10 configured as described above will be described.

  First, in the wiring apparatus 10, a wiring pattern of the electric wire 110 with respect to the target workpiece 100 is stored in advance.

  As a basic operation, the wiring apparatus 10 controls the XY robot 40 so that the relative movement trajectory of the head unit 20 with respect to the work 100 corresponds to the wiring pattern. Perform the movement.

  In the middle of the wiring operation, the operation is switched between the following first operation mode, second operation mode, and third operation mode. It should be noted that the mode to be switched in the course of the wiring operation is set in advance in association with the predetermined section of the wiring pattern. Which operation mode is preferably set for which section in the wiring pattern will be described later.

  In the first operation mode, the electric wire 110 is pushed out by the electric wire pushing mechanism 30 at an extrusion amount corresponding to the relative movement amount of the head unit 20 and the workpiece 100 so that the electric wire 110 is pressed against the wiring surface 101 of the workpiece 100. In this mode, the electric wire 110 is brought into contact with the wiring surface 101.

  The second operation mode is a mode for applying tension to the electric wire 110 by extruding the electric wire 110 with an extrusion amount smaller than the relative movement amount between the workpiece 100 and the head unit 20.

  The third operation mode is a mode in which the electric wire 110 is pushed out from the head portion 20, the head portion 20 is relatively moved so as to return the wiring path with respect to the workpiece 100, and the electric wire 110 is pushed inward.

  This will be described more specifically with reference to FIG. FIG. 6 shows an enlarged view of the main part of the wiring pattern of the electric wire 110 on the wiring surface 101 of the workpiece 100.

  In the figure, three sets of guide convex portions 102a, 102b, and 102c are provided in a projecting manner in such a manner that they are arranged with an interval in which the electric wire 110 can be arranged therebetween. Then, after the electric wire 110 from the side of the guide convex portion 102a on one side (the left side in FIG. 6) is bent into a substantially L shape along one end portion of the guide convex portion 102a, the guide convex portion 102a. And the central guide projection 102b. Next, the electric wire 110 is bent so as to be folded back in a substantially U shape along the other end portion of the central guide convex portion 102b, and the central guide convex portion 102b and the other side (right side in FIG. 6) are bent. It is wired so as to pass between the guide convex portion 102c. The electric wire 110 is bent in a substantially L shape along one end of the guide protrusion 102c on the other side and wired so as to be led out to the side.

  In such a wiring pattern, by simply extruding the electric wire 110 from the head portion 20, a portion where the electric wire 110 can be disposed without floating from the wiring surface 101, for example, the electric wire 110 is guided by the guide protrusions 102 a, The wire 110 is laid out in the first operation mode in the section M1 (route indicated by a broken line in FIG. 6) that is laid out so as to be bent in a substantially L shape or a substantially U shape along the lines 102b and 102c. .

  That is, when the head unit 20 relatively moves in the section M1, the relative movement between the workpiece 100 and the head unit 20 is performed so that the electric wire 110 can be pressed against the wiring surface 101 as shown in FIG. The wire push-out mechanism 30 pushes out the wire 110 with a push-out amount corresponding to the amount (the amount of movement of the workpiece 100 in this embodiment). Specifically, the relative movement amount in the section M1 is calculated based on a pre-stored wiring pattern or the like. Then, while the head unit 20 relatively moves in the section M1, the rotation amount, the rotation speed, and the like of the roller rotation driving unit 34 of the wire pushing mechanism 30 are controlled so as to push the wire 110 corresponding to the relative movement amount. In practice, the rotation amount, rotation speed, and the like of the roller rotation driving unit 34 are appropriately adjusted in consideration of the slip amount between the electric wire 110 and the pair of extrusion rollers 32a and 32b.

  Thereby, the electric wire 110 can be wired in a state in which the electric wire 110 is pressed against the wiring surface 101 and is more reliably brought into contact with the wiring surface 101. Further, at this time, since the head portion 20 itself is configured to push the electric wire 110 toward the wiring surface 101, there is an advantage that the electric wire 110 is hardly rubbed against the side surfaces of the guide convex portions 102a, 102b, and 102c.

  Further, in the wiring pattern as described above, when the electric wire 110 can be pulled, for example, the electric wire 110 is bent into a substantially L shape or a substantially U shape along the guide convex portions 102a, 102b, 102c. The wire 110 is routed in the second operation mode in the section M2 (route indicated by the alternate long and short dash line in FIG. 6) in which the wires are arranged in a straight line after the wires are arranged.

  That is, when the head unit 20 relatively moves in the section M2, as shown in FIG. 8, the extrusion amount is smaller than the relative movement amount between the workpiece 100 and the head unit 20 (the movement amount of the workpiece 100 in this embodiment). Thus, the wire pushing mechanism 30 pushes the wire 110. Specifically, the relative movement amount in the section M2 is calculated based on a pre-stored wiring pattern or the like. Then, while the head unit 20 relatively moves in the section M2, the rotation amount of the roller rotation driving unit 34 of the wire pushing mechanism 30 is pushed so as to push out the wire 110 having a smaller amount (length) than the relative moving amount, Control the rotation speed.

  Thereby, the electric wire 110 can be pulled by the linear wiring portion in a state where the electric wire 110 is hooked on the guide convex portion 102a (102b, 102c) at the bent portion. Thereby, tension | tensile_strength can be assign | provided to the electric wire 110, and the bend can be corrected and straightened.

  In the second operation mode, the electropneumatic force of the pressure cylinder 36 is set so that the pinching force of the electric wire 110 by the pair of push rollers 32a and 32b is smaller than the pinching force in the first operation mode. The regulator 37a is controlled. As a result, the electric wire 110 can be appropriately slid out from between the pair of extrusion rollers 32a and 32b, and accordingly, an appropriate tension can be applied to the electric wire 110 to extend the curl.

  Incidentally, FIG. 9 is a diagram showing a wiring mode in which the second operation mode is not performed in the section M2. In this case, if the curled wrinkle is generated in the electric wire 110 itself, the electric wire 110 that has left the curled wrinkle is wired in the straight section M2. For this reason, the electric wire 110 may wave and float from the wiring surface 101 in the section M2.

  On the other hand, as shown in FIG. 8, the electric wire 110 is wired in the second operation mode and tension is applied to the electric wire 110, so that the electric wire 110 can be extended and wired. is there.

  Furthermore, in the wiring pattern as described above, in the section M3 (a route indicated by a two-dot chain line in FIG. 6) that is a linear wiring pattern portion and in particular the electric wire 110 is likely to float from the wiring surface 101, The electric wire 110 is wired in the third operation mode. The part where the electric wire 110 is likely to float can be experimentally specified by actually arranging the electric wire 110 with respect to the workpiece 100.

  That is, as shown in FIG. 10, a portion where the electric wire 110 is likely to float from the wiring surface 101 may occur in the straight wiring path portion regardless of whether or not the electric wire 110 is bent. In this case, as shown in FIG. 11, after the head portion 20 passes through the linear wiring path portion while pushing the electric wire 110 for a predetermined distance, the head portion 20 pushes the electric wire 110 while passing the wiring route. Move relative to turn back. Then, when the head unit 20 is turned back by a predetermined distance, the head unit 20 moves again along the forward direction of the wiring path. Thereby, the electric wire 110 drawn out excessively from the head part 20 will be pressed against the wiring surface 101 while bending, and the electric wire 110 will be more reliably pressed against the wiring surface 101.

  According to the wiring apparatus configured as described above, the head unit 20 that guides the electric wire 110 toward the workpiece 100 and the XY robot 40 that relatively moves the workpiece 100 are provided. Since the wire pushing mechanism 30 that can push the wire 110 toward the wiring surface 101 of the workpiece 100 is provided, the wire 110 can be wired while being pushed from the head portion 20 toward the wiring surface 101 of the workpiece 100. it can. Therefore, as in the prior art, there is a mechanism for rotating the head portion 20 so that the guide roller for guiding the drawn-out electric wire 110 and the pressing pin for pushing the electric wire are located on the rear side with respect to the wiring direction of the electric wire. The wiring device can be reduced in size and cost can be reduced.

  More specifically, in the first operation mode, the electric wire 110 is pushed with an extrusion amount corresponding to the relative movement amount of the work 100 and the head unit 20 so that the electric wire 110 is pressed against the wiring surface 101 of the work 100. Since it has extruded, it can wire more reliably in the state which made the electric wire 110 contact the wiring surface 101. FIG.

  In addition, since the head portion 20 itself is configured to route the electric wire 110 by pushing the electric wire 110, the electric wire 110 and the side surfaces of the guide convex portions 102, 102a, 102b, and 102c rub against each other. Can be prevented as much as possible. Further, there is no need to incorporate a conventional guide roller, a pressing pin, or the like at the tip portion of the head portion 20, and it can be expected that the size is reduced, the durability is improved, and the maintenance is improved.

  Further, in the second operation mode, the electric wire 110 is extruded with an extrusion amount smaller than the relative movement amount of the workpiece 100 and the head unit 20, thereby applying tension to the electric wire 110 and eliminating the bending wrinkles. be able to.

  In this case, the pressure cylinder 36 is controlled so that the pinching force of the electric wire 110 by the pair of extrusion rollers 32a and 32b in the second operation mode is smaller than the pinching force in the first operation mode. Thus, the electric wire 110 can be appropriately slid out from between the pair of extrusion rollers 32a and 32b, and an appropriate tension can be applied to the electric wire 110.

  Further, in the third operation mode, while the electric wire 110 is pushed out from the head portion 20, the head portion 20 moves relatively so as to return the wiring path with respect to the workpiece 100, thereby pushing the electric wire 110 to the workpiece 100 more reliably. Can be attached.
