JP 2001-126942 A

  However, in the wiring device having the single wiring head as described above, it takes time to form the wiring pattern of the linear conductor on the base material, and the planar transformer and the planar coil are efficiently manufactured. There is a problem that it cannot be efficiently wired to a circuit board or the like.

  In order to solve such a problem, a plurality of wiring heads of the above-described wiring apparatus are arranged, and the plurality of wiring heads are simultaneously reciprocated in the vertical direction by a common vertical reciprocating means, and each wiring line is moved. It is also conceivable that the linear conductors respectively fed from the heads are sequentially applied along the wiring pattern while being intermittently brought into point contact with the surface of the base material and simultaneously arranged.

  However, in the wiring device having such a configuration, the plurality of wiring heads reciprocate at the same timing, so that the vibration generated thereby becomes stronger due to an increase in the overlapping of the waveforms. For this reason, it becomes difficult to properly wire the conductors along the wiring pattern while intermittently making point contact with the surface of the base material, making it impossible to form a highly accurate wiring pattern. Therefore, there is a problem that it is impossible to manufacture a planar transformer, a planar coil, or the like with high accuracy, or to perform electrical wiring with high accuracy on a circuit board or the like.

  The present invention solves the above-mentioned problems, and by arranging a linear conductor on the surface of a base material along a predetermined wiring pattern, a planar transformer, a planar coil, etc. can be manufactured efficiently and efficiently, a circuit board, etc. It is another object of the present invention to provide a highly productive wiring apparatus that can efficiently and efficiently perform electrical wiring.

  In order to achieve the above object, the invention described in claim 1 of the present invention is a wiring head for applying a linear conductor to a surface of a base material having an adhesive layer on the surface while intermittently making point contact with the surface.

The vertical reciprocating means for reciprocating other wiring heads is configured to reciprocate the wiring heads at different timings.

  According to a second aspect of the present invention, in the wiring device according to the first aspect, the vertical reciprocating means comprises an eccentric cam mechanism, and the eccentric cam mechanism has an eccentric cam mechanism in at least one vertical reciprocating means. However, it is configured to rotate at a different phase or frequency with respect to the eccentric cam of the eccentric cam mechanism in the other vertical reciprocating means.

  According to a third aspect of the present invention, in the wiring device according to the first aspect, the vertical reciprocating means comprises a crank mechanism, and the crank of the crank mechanism in at least one vertical reciprocating means is the other. The vertical reciprocating means is configured to rotate at different phases or frequencies with respect to the crank of the crank mechanism.

  According to the wiring device of the first aspect of the present invention, a plurality of wiring heads are arranged, and at least one wiring head is reciprocated at different timing with respect to the other wiring heads. The vibration generated by the reciprocating movement of these wiring heads is weakened by the reduction of the overlapping of the waveforms. As a result, it becomes easier to correctly wire the conductor by applying it along the wiring pattern while intermittently making point contact with the surface of the base material, and to efficiently form a highly accurate wiring pattern. it can. Therefore, a planar transformer, a planar coil, etc. can be manufactured efficiently and efficiently, or electrical wiring can be performed efficiently and efficiently on a circuit board or the like.

  According to the wiring device of the second aspect of the present invention, the vertical reciprocating means comprises an eccentric cam mechanism, and the eccentric cam of at least one eccentric cam mechanism is different from the eccentric cam of another eccentric cam mechanism. Since it is configured to rotate at different phases or frequencies, a highly accurate wiring pattern can be formed, and the structure of the apparatus is simple and not easily broken down, making it easy to handle.

  According to the wiring device of the third aspect of the present invention, the vertical reciprocating means comprises a crank mechanism, and the crank of at least one crank mechanism has a different phase or frequency relative to the cranks of the other crank mechanisms. Since it is configured to rotate, it is possible to form a highly accurate wiring pattern, and the structure of the apparatus is simple and does not break down, making it easy to handle.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing a basic configuration when the wiring device according to the present invention is applied to the production of a planar coil, and FIG. 2 is an example of a state in which the wiring head is attached to the horizontal moving means and an example of vertical reciprocating moving means. FIG. 3 is a diagram showing a state in which the wire conductor of FIG. 1 is used and the wire conductor is affixed to the surface of the base material while intermittently making point contact, and FIG. 4 is a plurality of wire heads. It is a schematic diagram which shows the arrangement | positioning state.

  In FIG. 1, 1 is a table as a holding mechanism for holding a rigid or flexible substrate A having an adhesive layer on the surface. The table (holding mechanism) 1 has a role of placing the base material A on the upper surface thereof and serving for forming a planar coil by the linear conductor B on the base material A. The table 1 may be realized as a conveyor mechanism or the like that is used for forming a planar coil while the substrate A is placed and conveyed at a constant speed.

  The base material A is provided with an adhesive layer made of a thermosetting rubber-based adhesive layer, a silicone-based adhesive layer, or the like having a certain adhesive force at normal temperature on its surface, for example, a tape-like or sheet-like base based on polyester or polyimide A flexible film (so-called adhesive tape) may be used, or the above-described adhesive layer may be formed on the surface of an insulating substrate or the like. Moreover, it is also possible to use a pressure-sensitive adhesive layer that exhibits tackiness when a pressing force from the wiring head 2 described later is applied, instead of the adhesive layer having viscosity at room temperature. Furthermore, it is also possible to use a UV (ultraviolet) curable adhesive layer, form a planar coil, etc., then cure the adhesive layer by UV irradiation, and firmly embed the planar coil in the adhesive layer. It is of course possible to use a thermosetting adhesive.

  On the side of the table 1 that holds the base material A, a horizontal moving means 3 that includes an XY table that supports the wiring head 2 is provided. The wiring head 2 affixes a linear conductor B as a material for forming a planar coil along the predetermined wiring pattern on the surface of the substrate A having an adhesive layer on the surface while feeding it from the tip of the nozzle. By doing so, it plays a role of forming a planar coil. As will be described later, the wiring head 2 is formed by the vertical reciprocating means 4 so that the linear conductor fed from the nozzle tip can be intermittently brought into point contact with the surface of the base A. It is provided so as to be freely reciprocated (up and down) intermittently in the vertical direction on the surface.

  The horizontal moving means 3 supports the wiring head 2 so as to move horizontally on the surface of the substrate A along the wiring pattern of a predetermined conductor B, that is, two-dimensionally (planarly). Yes. The plane movement of the wiring head 2 by the horizontal moving means 3 is performed in advance with respect to the vertical reciprocation of the wiring head 2 under the control of the control unit 5 made of a microprocessor or the like. This is performed by moving the wiring head 2 by a predetermined distance along the pattern.

  For example, as shown in FIG. 2, the wiring head 2 includes a shaft portion 8 that is supported by a support arm 6 fixed to a horizontal moving means 3 so as to be movable in a vertical direction via a thrust bearing 7. It has a structure in which a nozzle (wiring nozzle) 9 for feeding out the conductor B is attached to the lower end of the shaft 8.

  An eccentric cam mechanism 10 that is a vertical reciprocating means 4 is provided at the upper end of the shaft portion 8. The eccentric cam mechanism 10 includes an eccentric cam 11 that is rotationally driven by a motor (not shown) at a predetermined rotational speed, and a cam follower 12 that is fitted so as to surround the cam. As shown in FIG. 2, the eccentric cam 11 is, for example, one in which a disc body rotates eccentrically. The nozzle 9 of the wiring head 2 is reciprocated through the shaft portion 8 by the reciprocating movement of the cam follower 12 accompanying the rotation of the eccentric cam 11, that is, the nozzle 9 of the wiring head 2 is moved by one rotation of the eccentric cam 11. The reciprocating movement is made between the top dead center and the bottom dead center, and the nozzle tip is configured to intermittently contact the substrate A. The width of the reciprocating movement of the nozzle 9 (wiring head 2) is set to about 1 to 2 mm when a conductor B having a diameter of 0.3 mm is wired, for example. The cycle of the reciprocating movement of the nozzle 9 (wiring head 2) is set to about 50 Hz, for example, depending on specifications such as the speed required for the wiring processing.

  When the wire conductor B is wired using this wiring device, the wiring head 2 is moved in the horizontal direction along the wiring pattern set in advance by the horizontal moving means 3, and the wiring is performed. The head 2 is intermittently reciprocated in the vertical direction (vertical direction) at predetermined intervals without being synchronized by the vertical reciprocating means 4 (eccentric cam mechanism 10), and the conductor B is wired on the surface of the substrate A. May be. Further, the wiring may be controlled while the horizontal movement of the wiring head 2 and the vertical reciprocation of the wiring head 2 are synchronized with each other. Further, according to the wiring pattern, a point contact point (laying point of the conductor B) with respect to the base material A of the wiring head 2 is programmed in advance, and the wiring head 2 according to the horizontal movement of the wiring head 2. May be reciprocated.

  Then, the wiring head 2 is moved forward (down) in the vertical direction, the linear conductor B fed from the nozzle tip is instantaneously brought into point contact with the surface of the base A, and the conductor B is brought into contact with the base A. Affixed to the surface (adhesive layer) of the pin. Thereafter, the wiring head 2 is moved backward (raised), and the conductor B affixed to the surface of the base material A is fed out from the nozzle tip by the amount of backward movement (raised) of the wiring head 2. Then, the horizontal movement means 3 is moved to the cloth along with the backward movement (upward movement) of the wiring head 2 until the wiring head 2 is moved forward (lowered) again to make point contact with the surface of the substrate A. It moves by a predetermined amount in the direction determined by the line pattern.

  After such movement, the linear conductor B drawn out from the wiring head 2 is brought into point contact with the surface of the base material A again, and the conductor B is affixed to the moving position at a pinpoint. The conductor B is continuously pasted between the position where the conductor B is pasted. That is, the surface (adhesive layer) of the base material A in which the linear conductor B drawn out from the nozzle tip of the wiring head 2 is intermittently point-contacted by two reciprocating movements accompanying the horizontal movement of the wiring head 2. The conductor B is pasted between two points. Thereafter, the conductor B is stuck at a pin point by intermittent reciprocating movement of the wiring head 2 by the vertical reciprocating means 4 and horizontal movement of the wiring head 2 according to the wiring pattern by the horizontal moving means 3. By repeatedly performing it sequentially, the linear conductors B are sequentially attached to the surface of the base material A along a predetermined wiring pattern.

  That is, as schematically shown in FIG. 3, the wiring head 2 is reciprocated in the vertical direction and, for example, the wiring head 2 is moved in the horizontal direction along the wiring pattern in synchronization with the reciprocation. Then, the wire B 2 is brought into contact with the surface of the base material A as shown by P1, P2, P3,... Are sequentially attached to the surface of the base material A along the wiring pattern in a pinpoint manner.

  The linear conductor B is supplied by being wound around a bobbin C, and is continuously supplied to the wiring head 2 via a tensioner 6a, a guide sheave 6b, and the like. The conductor B varies depending on the specifications of the planar coil, the wiring pattern, etc., but it is not only a so-called bare copper wire but also an enameled wire in which a copper wire is insulated with a synthetic resin (enamel coating having a circular or flat cross section). A copper wire), a litz wire obtained by twisting a plurality of enamel wires, or the like is used as appropriate.

  In the wiring apparatus of the present invention, at least a plurality of wiring heads 2 and vertical reciprocating means 4 are provided, and vertical reciprocating means 4 for reciprocating at least one wiring head 2 is another wiring head. The wiring head 2 is configured to reciprocate at different timings with respect to the vertical reciprocating means 4 that reciprocally moves 2.

  In the wiring apparatus according to the present embodiment, for example, as shown in FIG. 4, the eccentric head mechanisms 10A, 10B, 10C, and 10D that are the wiring heads 2A, 2B, 2C, and 2D and the vertical reciprocating means 4 are independent of each other. Are arranged in parallel to the base material A at a predetermined interval. Then, the eccentric cam 11A of the eccentric cam mechanism 10A for reciprocating the wiring head 2A is set so that the top portion (the portion farthest from the eccentric shaft center) is at the upper position. Further, the eccentric cam 11B of the eccentric cam mechanism 10B that reciprocates the wiring head 2B is set so that the top portion is in the right position by rotating 90 degrees clockwise relative to the eccentric cam 11A. Further, the eccentric cam 11C of the eccentric cam mechanism 10C for reciprocating the wiring head 2C is set so that the top portion is in the lower position by rotating 90 degrees clockwise relative to the eccentric cam 11B. Further, the eccentric cam 11D of the eccentric cam mechanism 10D for reciprocating the wiring head 2D is set so that the top is at the left position by rotating 90 degrees clockwise relative to the eccentric cam 11C.

  When the eccentric cam 11A to the eccentric cam 11D of the eccentric cam mechanism 10A to the eccentric cam mechanism 10D are individually provided or rotated in synchronism in the same direction at the same rotational speed by one common motor (not shown). The eccentric cam 11A to the eccentric cam 11D rotate at phases different by 90 degrees. Accordingly, the wiring head 2A to the wiring head 2D are reciprocated in the vertical direction at different timings (phases), and the four linear conductors B are formed on the surface of the substrate A as described above. It becomes possible to apply them sequentially along the wiring pattern and to wire them at the same time.

  Note that the eccentric cams of any one or two eccentric cam mechanisms are different from the eccentric cams of the other three or two eccentric cam mechanisms instead of all of the eccentric cam mechanisms 10A to 10D. You may make it rotate at a phase and to reciprocate any one or two wiring heads in the perpendicular direction at a different timing (phase) with respect to the other three or two wiring heads. Further, instead of setting the eccentric cams 11A to 11D of the eccentric cam mechanisms 10A to 10D to be the same, the eccentric cams of at least one eccentric cam mechanism are used as the eccentric cams of other eccentric cam mechanisms. On the other hand, by rotating in the same direction so that the phases are different, at least one wiring head may be reciprocated at different timings (phases) with respect to other wiring heads. Further, the eccentric cam of at least one eccentric cam mechanism has the same phase in the same direction as the eccentric cam of the other eccentric cam mechanism, but is rotated at different rotational speeds, and at least one wiring head is replaced with another one. You may make it make it reciprocate with a different timing (frequency) with respect to this wiring head. Furthermore, the eccentric cam 11A to the eccentric cam 11D may be provided coaxially with an outer peripheral contour having an irregular shape (non-circular shape). The horizontal moving means 3 may be arranged in a plurality (four in the illustrated example) together with the wiring head 2 and the vertical reciprocating moving means 4, but in the case where a plurality of the same wiring patterns are formed simultaneously. Alternatively, one common horizontal moving means 3 may be provided. The bobbin C, the tensioner 6a, the guide sheave 6b and the like for supplying the linear conductor B are preferably provided for each of the plurality of wiring heads 2A, 2B, 2C, and 2D.

  According to the wiring device of the present invention, a plurality of wiring heads 2A, 2B, 2C, and 2D are arranged, and at least one wiring head is set at a different timing (phase or frequency) with respect to other wiring heads. Since the reciprocating movement is performed, the vibration generated by the reciprocating movement of the wiring heads 2A, 2B, 2C, and 2D is weakened due to a decrease in the overlapping of the waveforms. As a result, the linear conductor B is sequentially affixed along the wiring pattern while intermittently making point contact with the surface of the base material A, and it becomes easy to correctly perform wiring, and a highly accurate wiring pattern is efficiently formed. be able to. Therefore, a planar transformer, a planar coil, etc. can be manufactured efficiently and efficiently, or electrical wiring can be performed efficiently and efficiently on a circuit board or the like.

  The vertical reciprocating means 4 comprises an eccentric cam mechanism 10A to an eccentric cam mechanism 10D, and the eccentric cam of at least one eccentric cam mechanism has a different phase or frequency with respect to the eccentric cams of the other eccentric cam mechanisms. It is preferable to be configured to rotate, because a highly accurate wiring pattern can be formed, and the structure of the apparatus is simple and does not easily break down, and is easy to handle.

  FIG. 5 is a schematic view showing a crank mechanism 13 which is a modification of the vertical reciprocating means 4. The crank mechanism 13 is provided at the upper end of the shaft portion 8 of the wiring head 2. The crank mechanism 13 includes a crank 14 that is rotationally driven by a motor (not shown) at a predetermined rotational speed, a slider 15 that is rotatably supported at the tip of the crank 14, and a shaft portion 8 that is disposed above the shaft portion 8. And a guide frame 16 having a groove fixed in a vertical direction with respect to the slider 15 and slidably fitted to the slider 15. Then, by rotating the crank 14 at a predetermined rotational speed, the slider 15 is reciprocated in the horizontal direction (perpendicular to the shaft portion 8) along the guide frame 16 so that the crank 14 rotates. The reciprocating movement of the slider 15 causes the nozzle 9 of the wiring head 2 to reciprocate in the vertical direction via the guide frame 16 and the shaft portion 8, that is, the rotation of the crank 14 causes the nozzle 9 of the wiring head 2 to move. The reciprocating movement is made between the top dead center and the bottom dead center, and the nozzle tip is configured to intermittently contact the substrate A. Therefore, the crank 14 in the crank mechanism 13 has the same function as the eccentric cam 11 in the eccentric cam mechanism 10. Therefore, as the vertical reciprocating means 4, for example, a description of the case where four crank mechanisms 13 are used instead of the four eccentric cam mechanisms 10A to 10D is omitted.

  The vertical reciprocating means 4 comprises a crank mechanism 13, and the crank 14 of at least one crank mechanism 13 is configured to rotate at a different phase or frequency with respect to the cranks 14 of the other crank mechanisms 13. In addition to being able to form a highly accurate wiring pattern, it is preferable because the structure of the apparatus is simple and does not break down easily and is easy to handle.

  In the above embodiment, the wiring head 2 is moved in the horizontal direction along the wiring pattern of the conductor B on the surface of the base material A, but it is configured to move horizontally on the base material A side. Is also possible. In this case, the base material A may be held on the horizontal moving means 3. Moreover, although the wiring head 2 is reciprocated in the direction perpendicular to the surface of the substrate A, it is needless to say that the substrate A side may be reciprocated.
