The present invention relates to an improvement of a molding processing apparatus for applying a voltage between the lead wires of a deflection coil of the present invention to maintain a coil shape.

Deflection coils for use in CRTs and the like are generally shaped to have a special shape, such as a saddle shape and the like, in order to maintain their shape in the shape of a coil without a core.

In order to reduce the induction loss, winding wire rods are used, for example, in which a large number of covering wires insulated and coated around a thin ferry boat are combined. Winding is performed using an exclusive mold, and a predetermined voltage is applied to the coil after the winding operation to heat and melt the coating material of the coating wire by heat generation in accordance with the resistance of the conductor, and weld the coating wire to each other. As a result, the wire rod increases rigidity by integrating the coated wire, and the coil maintains the saddle shape without causing a change in mold even when it is removed from the mold.

Therefore, although energization after winding is performed by connecting an electrode to the lead wires of both ends of a winding, it is necessary to reliably connect an electrode to the conducting wire inside an insulation coating at this time.

For this reason, although the insulation coating was conventionally heated by a heater or a high frequency and peeled from the conductor, there existed a possibility that the peeled coating body adhered to the conductor and may cause the electricity supply failure at the time of energization.

Thus, for example, Japanese Patent Application Laid-Open No. 61-208818 proposes an apparatus in which an edge breaks a covering material so as to directly contact a wire by holding a lead wire with an electrode-compatible clamp member having an uneven surface having an edge. have.

However, in this apparatus, since the covering material itself is not removed, there is a problem that the reliability of contact between the electrode and the conductive wire is defective.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and in the winding machine of a deflection coil, a molding mechanism which reliably connects the lead wire and the electrode for heating welding at the start or end of the winding of the deflection coil, and rationally performs the molding after the winding.

According to the invention of claim 13, the crimping portion is crimped to the wire made of the coated lead, and the crimped portion is cut into the inside of the coating by applying a voltage and cut at a predetermined position so as to form an electrode in electrical contact with the coated lead. As the crimped conductive member, a portion of the hoop material is cut out at a predetermined interval from the crimp portion and a claw for preventing the wire rod from escaping to the outside of the crimp portion during crimping.

The invention of claim 1 removes the first electrode from the side of the conductive member which melts and compresses the coating of the wire rod by applying a voltage to the conductive member crimping portion of the wire rod.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 6 show a first embodiment of the present invention.

The winding machine shown in FIG. 1 is equipped with the nozzle 1 as a wire rod supply mechanism which supplies a coil winding wire rod, and the metal mold | die 2 which winds a wire rod.

The nozzle 1 is supported via the nozzle up / down crank mechanism 7 on the movable table 3 moving in three axes by the front and rear motors 4, the left and right motors 5, and the up and down motors 6, It is comprised so that the movement of the three-axis direction and the up-down direction of the front-end | tip may be performed arbitrarily.

The wire rod 8 incorporating the coating wire which is thinner from the wire rod supply mechanism which is not shown in figure is guide | induced to the nozzle 1, and this wire rod 8 is supplied from the tip of the nozzle 1 under predetermined tension.

The metal mold | die 2 is comprised from the male mold 2a and the female mold 2b which can be separated up and down. The collection mold 2a and the female mold 2b rotate integrally with the rotation of the mold motor 9 while being in close contact with each other, and the wire 8 supplied from the nozzle 1 is wound around the joint portion. The winding is shaped into a saddle shape.

Further, in order to press the conductive member 12 as shown in FIG. 5 to the wire 8 at the start of winding and the end of the winding, the crimping and energizing mechanism 13 as shown in FIG. ) Is installed on the side.

The crimp energizing mechanism 13 includes an elastic cylinder 16 for driving the upper and lower electrodes 14 and 15 and the electrode 14 facing toward the electrode 15 and the cutter 17 integrally supported with the electrode 14. ). The welding power supply 28 shown in FIG. 4 is connected to the electrodes 14 and 15 via the switch 33. As shown in FIG. These electrodes 14 and 15 constitute a first electrode.

As shown in FIG. 3, the conductive member 12 bends a portion of the hoop material 18 that is continuous in a belt shape at a predetermined interval to approximately the rear side. It is bent so that it may become a female cross section, and this is cut | disconnected by the cutter 17, and is used. The crimping energizing mechanism 13 is provided with a cutter 32 as shown in FIG. 6 (b) for separately cutting the wire 8. This cutter 32 is provided with a drive mechanism (not shown) independent of the electrode 14, and the wire rod 8 in the vicinity of the conductive member 12 crimped to the wire rod 8 and at a position on the mold 2 side. To cut.

The hoop material 18 is supplied from the reel 20 shown in FIG. 1 to the crimp energizing mechanism 13 via the transfer mechanism 19 shown in FIG.

The conveyance mechanism 19 is provided with the groove | channel guide 21 of the groove type which extends from the bottom of the reel 20 to the crimp energization mechanism 13, and the slider 23 provided in the middle of the guide 21. As shown in FIG. The slider 23 slides along the guide 21 by the expansion and contraction of the expansion and contraction cylinder 24 mounted between the guide 21 and the guide 21. Square cutouts 25 are formed on both sides of the hoop material 18 at predetermined intervals, and the hoop material 18 is engaged with the cutouts 25 inside the slider 23 so as to slide the hoop material 18. And a claw 22 for moving toward the crimp energizing mechanism 13 integrally therewith. The claw 22 is pressurized toward the inside of the slider 23 by the spring 26, and the wedge-shaped tip protrudes toward the inside of the slider 23 in the state seen from above. The front surface of the claw 22 is perpendicular to the moving direction of the slider 23, and the rear surface is inclined to form an acute angle with the front surface. Accordingly, when the slider 23 is moved forward, that is, slides toward the crimp current supply mechanism 13, the hoop material 18 is moved forward by the claw 22 having the tip coupled to the notch 25 of the hoop material 18. On the other hand, if the slider 23 is retracted, i.e., slides in a direction away from the crimp energizing mechanism 13, the claw 22 is retracted with respect to the spring 26 while the inclined surface is slid along the notch 25. Since the hoop material 18 moves to the outside of the cutout portion 25, the hoop material 18 remains in the position up to that time, and only the slider 23 retreats.

The chuck 27 is attached to the water receiving mold 2a as a locking means of the conductive member 12. The chuck 27 is opened and closed in accordance with the expansion and contraction of the built-in cylinder, and the conductive member 12, which is moved from the crimping and energizing mechanism 13 by the movement of the nozzle 1, is locked to the collection mold 2a. The chuck 27 is made of a conductive material and, as shown in FIG. 4, is connected to the molding power supply 29 together with the electrodes 15 of the crimping and energizing mechanism 13 as the switch 33 is opened and closed. Since the chuck 27 rotates integrally with the collection die 2a, the connection of the forming power supply 29 to the chuck 27 is performed by the non-rotating portion of the base of the collection die 2a as shown in FIG. It is performed through the brush 30 provided in (2c). In addition, the chuck 27 and the electrode 15 constitute a second electrode.

The operation is explained next.

First, the crimping step of the conductive member 12 to the wire rod 8 will be described, followed by the winding of the coil and the shaping step.

When the expansion / closing cylinder 24 of the conveyance mechanism 19 is stretched and the slider 23 is driven forward, the hoop material 18 is sent out forward by the claw 22, and the uppermost end thereof is a crimped energizing mechanism ( It is fed between the electrodes 14, 15 of 13.

Next, the nozzle 1 is moved by the operation of the motors 4, 5, 6, and the wire 8 from the nozzle 1 is guided between the electrodes 14, 15. The wire rod 8 is sandwiched between the rearward bent portion located at the uppermost end of the hoop material 18 and the non-bent portion below it.

Here, when the electrode 14 and the cutter 17 are lowered by the expansion cylinder 16, the cutter 17 cut | disconnects the best end part of the hoop material 18 by 1 span. This cut | disconnected part is the quantity which crimped | bonded to the wire rod 8 as the electroconductive member 12. FIG.

On the other hand, the cut conductive member 12 is pressed between the electrode 14 and the counter electrode 15 is pressed to the wire 8 sandwiched between. At the same time, a voltage is applied to the electrodes 14 and 15 in the welding power supply, and the coating of the coating wire constituting the wire rod 8 is melted by the heat generated by the energization. The molten coating material is pushed laterally by the pressure applied to the conductive member 12, and the conductive member 12 is directly pressed against the conductive wire inside the coating line.

Next, the winding of the coil and the forming process will be described.

FIG. 5 (a) shows a state in which the conductive member 12 is pressed against the tip of the wire rod coming out of the nozzle 1. From this, the nozzle 1 is moved to move the conductive member 12 to the metal mold | die 2a, and the conductive member 12 is gripped by the chuck 27 as shown in FIG. 5 (b). Then, the collection mold 2a and the female mold 2b are integrally rotated by the operation of the mold motor 9, and the wire 8 which is fed under a predetermined tension from the nozzle 1 is collected. ) Is wound around the junction of the female die 2b. At the same time, the tip of the nozzle 1 is swung up and down as shown in FIG. 5 (c) to drive the nozzle up-and-down crank mechanism 7 to prepare the winding shape. As a result, a saddle-shaped coil is formed on the outer circumference of the mold 2.

When the winding operation is finished, the wire rod guided from the mold 2 by moving the nozzle 1 beyond the electrodes 14 and 15 to the opposite side of the mold 2 as shown in FIG. 5 (d) ( 8) is sandwiched between the conductive member 12. And the new conductive member 12 is crimped | bonded to the wire rod 8 as shown to FIG. 5 (e) by the process mentioned above.

Next, as shown in FIG. 6 (a), the molding power source 29 is formed between the electrode 15 and the chuck 27 with the conductive member 12 sandwiched between the electrodes 14 and 15. A predetermined voltage is applied. Accordingly, the coating of the coating wire of the wire rod 8 constituting the coil 31 is melted by energizing the coil 31 on the mold 2 via the conductive members 12 at both ends, More sheaths weld together. As a result of welding, the winding strength of the coil 31 becomes high, and the coil 31 is molded so as to maintain a saddle shape even in the state exiting the mold 2.

After molding, the wire rod 8 is cut by the cutter 32 as shown in FIG. 6 (b). Since the cutting is performed on the mold 2 side, as a result, the conductive member 12 is crimped only to the lead wire at the start of winding, and the lead wire at the end of winding is simply cut. In this state, the coil 31 is pulled out of the mold, and the conductive member 12 is cut off and dropped. The conductive member is used only for energization in the forming process of the coil 31, and since it is unnecessary after completion of the coil, the conductive member 12 is not already crimped on one side of the lead wire of the coil 31 from the mold. The trouble of breaking (12) is also reduced.

On the other hand, on the nozzle 1 side, as shown in FIG. 6 (c), the conductive member 12 is suspended in a crimped state at the tip of the wire 8 coming out of the nozzle 1. This is the same state as the fifth (a), and the same process is repeated for the next coil by moving the nozzle 1 and holding the conductive member 12 back to the chuck 27.

Therefore, only one conductive member 12 may be crimped with respect to one coil, and no irrationality occurs in the energization process by the molding power source 29 as compared with the case where the conductive member 12 is crimped on both ends of the coil. It is possible to greatly reduce the effort and material of the crimping work.

Moreover, since the nozzle 1 provided with the moving mechanism also serves as the moving means of the conductive member 12, there is no need to provide a moving means separately. Since the nozzle 1 guides the wire rod 8 to the crimping and energizing mechanism 13 and imparts a function of being sandwiched between the conductive members 12, the nozzle 1 is used to arrange the conductive member 12 on the outer circumference of the wire rod 8. No special features will be used. Moreover, since the nozzle 1 is moved, even if the size of the mold 2 is changed, the molding operation can be performed by the same apparatus without any special change.

7 shows a second embodiment of the present invention regarding the configuration of the conductive member 12. As shown in FIG.

In the present invention, instead of the hoop material 18 which is partially cut and bent as the conductive member 12, the elongated members 51 to 54 having various cross-sectional shapes as shown in the figure can be used. In this case, the shape of the crimping means (the electrodes 14 and 15 in the first embodiment) is changed according to the shape of the conductive member 12.

For example, in the third embodiment of the present invention shown in FIG. 8 and FIG. 9, the conductive member 12 is composed of an elongate member 50, and the shape of each tip portion of the electrodes 14, 15 is defined. It forms in the concave surface as shown in FIG.

The conductive member 12 pressed between the electrodes 14 and 15 deforms the wire 8 to be fitted at both sides. By further applying pressure while applying a voltage between the electrodes 14 and 15, the coating of the coating wire constituting the wire rod 8 melts as in the first embodiment, and is pressed laterally by a press. The electroconductive member 12 is crimped | bonded by the conducting wire inside a coating line. As such, the conductive member 12 may be formed in various shapes. 9 shows the shape of the conductive member 12 after pressing. In addition, in the case of forming the conductive member 12 into a complicated shape as in this embodiment, the electrodes 14 and 15 are separately provided with a mechanism such as a pressure rod, which will be described later, and the conductive member 12 is formed prior to energization. May be crimped.

10 (a) and 10 (b) show a fourth embodiment of the present invention.

In the first embodiment, the wire 8 guided by the mold 2 is fitted to the conductive member 12 by the movement of the nozzle 1, but here the robot arm 34 having a moving mechanism is provided. The wire 8 is gripped and fitted to the conductive member 12. The robot arm 34 is provided with a pair of arm members provided with the opening-closing mechanism for holding the wire 8. FIG. 11 shows a fifth embodiment of the present invention in which the robot arm 34 of the fourth embodiment is used for supplying the conductive member 12. As shown in FIG.

Here, the crimp electricity supply mechanism 13 and the transfer mechanism 19 are arrange | positioned in the position separated, and the robot arm 34 conveys the electroconductive member 12 to the crimp electricity supply mechanism 13.

Further, in the embodiment of FIG. 11, the robot arm 34 transfers the cutting mechanism after cutting the conductive member 12 made up of the hoop material 52 shown in FIG. In (19), the pressure transfer mechanism (13) is moved.

12 (a) and 12 (b) show a sixth embodiment of the present invention using the robot arm 34 as a means for moving the conductive member 12 pressed against the wire rod 8 to the chuck 27. Illustrated.

Here, as shown in FIG. 12 (a), the robot arm 34 first moves to the crimp energizing mechanism 13 to grasp the conductive member 12 that is pressed onto the wire 8, whereby the twelfth ( As shown in the diagram b), the wire rod 8 is released even when the chuck 27 grips the wire rod 8 by moving to the chuck 27.

In this way, by providing the robot arm 34, the moving mechanism of the nozzle 1 can be omitted.

13 (a) and 13 (b) show a seventh embodiment of the present invention.

This embodiment includes a moving mechanism for integrally moving the crimping energizing mechanism 13 and the conveying mechanism 19, and mounting of the conductive member 12 to the wire rod 8 is performed by such movement.

In FIG. 13 (a), the edge part unwound from the nozzle 1 is wound around the metal mold | die which is not shown in figure. In this state, the wire crimping mechanism 31 and the transfer mechanism 19 are moved, and the wire rod 8 is inserted into the conductive member 12 at the tip of the transfer mechanism 19 as shown in FIG. 13 (b). In the same manner as in the first embodiment, the crimping and energizing mechanism 13 cuts and cuts the conductive member 12 by the cutter 17, presses the scattered material 8, and conducts electricity through the electrodes 14 and 15. After the wire rod crimping mechanism 13 and the transport mechanism 19 are moved to the original position. Since the nozzle 1 does not move, the conductive member 12 compressed to the wire rod 8 stops at that position.

By providing the movement mechanism in the crimped energizing mechanism 13 as described above, the conductive member squeezed to the wire 8 as in the eighth embodiment of the present invention shown in FIGS. 14 (a) to 14 (c) ( 12 can be moved to the chuck 27 by the crimp energizing mechanism (13). In this case, as shown in FIGS. 14 (a) and 14 (b), the crimp current carrying mechanism 13 holding the conductive member 12 crimped to the wire rod 8 is mounted on the mold 2a. 27) The conductive member 12 is pushed forward by the transfer mechanism 19 while the electrode 14 and 15 are moved away from each other as shown in FIG. 14 (c). It is good to grip with (27).

In this case, the wire rod from the nozzle 1 to the mold 2 passes between the electrodes 14 and 15 of the crimping and energizing mechanism 13 and does not move the wire rod 8 in particular. 8) the conductive member 12 can be crimped. The conductive member pressed onto the wire 8 is conveyed to the chuck 27 by moving the nozzle 1 in a direction orthogonal to the central axis of the mold 2 as in the ninth embodiment.

In this manner, even when the nozzle 1 is provided with a moving mechanism, the moving direction can be limited, and accordingly, the moving mechanism can be simplified.
