Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an apparatus for manufacturing a deflection coil, specifically, a device for manufacturing a deflection coil, which rotates a pair of winding jigs for forming a deflection coil by winding a wire into a cavity at an abutting portion. The present invention relates to a type of deflection coil manufacturing apparatus in which a wire is wound into a cavity through this rotation, and is used, for example, to manufacture a deflection coil that changes an electron beam from outside the tube.

2. Description of the Related Art This type of deflection coil manufacturing equipment revolves around a winding jig unit in which a wire rod is passed through the winding jig unit. Since then, it has been provided and used as an alternative device for those that cannot withstand the recent higher speeds of operation.

Each of the winding jigs brought into abutting state is individually supported and rotated, and is moved toward and away from the jig in order to take out the formed deflection coil and to form the next deflection coil.

Problems to be Solved by the Invention The device using the winding jig rotation method can perform winding for forming a deflection coil simply by rotating the winding jig, and can perform one part of high-speed winding production. It is easy to operate at high speeds without increasing its size. However, both of the winding jig units are supported and rotated separately, and furthermore, they are moved toward and away from each other each time the deflection coil is formed, so the structure around the winding jig becomes relatively complex and large. In particular, the method of moving the winding jigs that the present inventors have conceived is such that two winding jigs are sequentially moved cyclically between two positions, and the task of forming the deflection coil is shared between the two positions at the same time. The conventional individual support method is not suitable for cases where it is desired to improve productivity by progressing.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a pair of winding jigs for forming a deflection coil by winding wire rods around mutual butt portions by rotation. The winding jig unit is detachably connected and is held on one of the winding jig sides, and includes attachment/detachment means for attaching and detaching the winding jig on the side that is not held to the held winding jig. do.

The pair of winding jigs that form the working deflection coil are removably connected as a winding jig unit, so that they can be driven together by holding only one of the winding jigs on a cantilever. It is stably supported, and the support and rotational drive structure around the pair of winding jigs is simplified. Further, thereby, the pair of winding jigs can be moved in a state where the deflection coil can be formed without making the device particularly large or complicated. Uni 7
Since the pair of coiled winding jigs can be attached and detached as necessary by the attachment/detachment means, it is possible to form and take out the deflection coils in the same manner as in the case of individual support.

A series of operations will be explained below. The plurality of wire rods A1 supplied from the wire rod supply means 38 are brought into alignment through a guide roller 49 and a wire rod passing guide 34, and further passed through a guide rod 35 and clamped by a wire rod clamper 44 of a starting end handling means 40. (Figure 5). In this state, the entire device is started. At the upper stop position of the winding jig unit 56, the driving means 14 is first advanced by the air cylinder 15 as shown by arrow A in FIG.
The positioning pin 29 is fitted into the positioning hole 28 of the swing holder 3 like an arrowhead to position the swing holder 3 at a predetermined stop position. The drive means 14 is further advanced to connect the friction coupling part 17 to the corresponding winding jig unit 56 at the upper stop position.

Next, the operating rods 20 on both sides are advanced by the air cylinders 27 as shown by the arrow c in FIG. The winding jig 5.6 is biased by springs 8 and 11.
The lock pin 7 that is locked in the connected state is further pushed into the locked state. In addition, the other operating rod 20 is used to push the detent lever 21 to release the detent of the winding jig 5 caused by the detent lever 21.

In this state, the wire rod threading guide 34 is moved to the retracted position shown in FIG. 5 by the cylinder 32, and the winding jig unit 56 is slightly rotated in the two directions indicated by arrows in FIG. 1. Alignment of end clamper 61 and wire rod A1; The position of the first passive arm 64c of the clamper opening/closing tool 64 is adjusted so that it faces the operating lever 66.

At the same time, the head 45, which clamps the starting end of the wire A1 with the clamper 44, is moved to face the winding starting end clamper 61 on the winding jig 5, and then the air cylinder 39 moves to the direction indicated by the arrow in FIG. The starting end of the wire material AI being clamped is carried into the winding starting end clamper 61 which is opened as shown in FIG. Subsequently, the operating lever 66 is rotated in the direction of the arrow in FIG. The end clamper 61 is closed. As a result, the winding start end clamper 61 clamps the start end of the wire rod 81 carried inside.

In this state, the winding jig unit 56 is rotated once in the two directions indicated by arrows in FIG. At this time, the wire A1 is connected to the recess 5c of the winding jig 5 and the guide pin 6 for measuring the winding start end and forming the wire A2.
8 (Figures 9 and 13), it is dropped into cavity a in the latter half. This ensures that the wire At is wound into the cavity a in an initial state. After passing through this initial state, the wire rod threading guide 34 is advanced in the two directions indicated by the arrows in FIG. As shown, it is further rotated in the direction of arrow T by the required number of windings. As a result, only the necessary winding bones of wire Al are wound into the cavity a, and the first wire rod Al is wound into the cavity a.
0 is formed into a deflection coil configuration of the desired shape as seen in FIG. Next, the wire rod threading guide 34 is retreated in the direction of the arrow ``nu'', and the winding jig unit 56 is reversed as shown by the arrow ``l'', so that the end of the winding of the wire rod Al is connected to the winding jig 5. The hooks are aligned with the recess 5C and the guide pin 69 as shown in FIG. Next, the winding jig unit 56 is further reversed slightly as shown by arrow 2 in FIG. By being moved back greatly, the wire A1 is pulled rearward and carried into the winding end clamper 62 which is in an open state on the winding jig 5. Next, the operation lever 66 is moved to the seventh position by the operation of the air cylinder 67.
The first passive arms 6 are rotated in the two directions indicated by the arrows in the figure and are facing each other.
5c to close the winding end clamper 62 by the cam 65a of the clamper opening/closing tool 65. As a result, the winding end clamper 62 clamps the winding end 3e portion of the wire A1 carried inside as shown by the arrow mark.

At this point, as shown in FIG. 12, the winding end 45 is swung in the horizontal direction to a position facing the winding end clamper 62, and then advanced in the direction of the arrow W and clamped by the clamper 62. At the same time, the wire rod AI is held between the supply side as shown by the arrow force, and the wire rod Al is held under the pinched area by the wire rod force.
The wire is cut by the ivy 50 as shown by the arrow mark, and the head 45 returns to the original position and waits while clamping the cut wire portion that has become the starting end.

Further, the drive means 14 is moved backward in the direction of the arrow y in FIG. 17, and the connection with the winding jig unit 56 located at the upper stop position of the frictional connection portion 17 is released. This completes the winding work in the winding jig unit 56 located at the upper stop position.

After the winding work, the rotating shaft 2 is rotated 180 degrees in the direction of the arrow, and the winding jig unit 56 that has finished the winding work is moved to the lower stop position.

For the winding jig unit 56 in the lower stop position,
As shown in FIG. 13, the large hydraulic cylinder 85 extends in the direction of the arrow mark to advance the press plate 87 into the cavity a, and as shown in FIG. 14, the hydraulic cylinder 110 extends in the direction of the arrow mark. The moving board 111
is advanced and presses the press plate 113 into the cavity a, so that the deflection coil form A4 formed in the cavity a is pressed from both sides in the cavity a, and the wire rod parts 1 are brought into close contact with each other.

At the same time, as shown by arrows in FIG. 13, the current supply head 90 is moved upward by the air cylinder 89, and the lead wire A2 on the winding start end side and the lead wire on the winding end end side of the wire A1 are moved upward. Clamper 61.6 clamping 3
2, the deflection coil form A4 is energized through the clampers 61 and 62, and the Joule heat generated in the wire ^1 fuses the surface adhesive layer of the wire A1, and the wire part 1 is integrated into the first A deflection coil A as shown in FIG. 20 is formed.

Note that the pressing operation of the deflection coil form 4 can also be performed more effectively by small-scale expansion and contraction of the small hydraulic cylinder 86. The small hydraulic cylinder 86 serves for adjusting the clamping coverage point during the clamping of the deflection coil configuration A4 by the two presses 87,113. - Next, with the movable board 111 in the forward position, the operating rod 118 of the attachment/detachment means 84 is advanced by the air cylinder 119 in the direction of arrow N in FIG. Move the operating section 10a in the clamp release direction (
Push in the direction indicated by the arrow in Figure 3). As a result, the bell crank 10 moves the lock pin 7 in the direction of the arrow in FIG. 2 against the spring 11 acting on itself and the spring 8 acting on the lock pin 7, and 6a through the horizontal hole 6b.

At the same time, the current supply head 90 is lowered in the direction indicated by the arrow mark in FIG. 17, and the upper and lower jig holding parts 114 are rotated in the direction indicated by the arrow mark in FIG. 17, in which the outer peripheral portion is engaged with the engagement groove 6c, and the winding jig 6 is placed between the upper and lower jig holding parts 114. It will be in a state where it will be held.

Next, the operating rod 101 between the energizing means 82 is moved upward in the direction of the arrow in FIG. ,
The clamping of the winding start end lead wire section 2 and the winding end end lead wire section 3 by the clampers 61 and 62 is released.

In this state, the movable substrate 111 is moved backward in the direction of arrow O in FIG. 19 while holding the winding jig 6, separating the winding jig 6 from the winding jig 5 and opening the cavity a.

With the cavity a opened, the press plate 87 is advanced in the direction of the arrow in FIG. 20 by the small hydraulic cylinder 86, and pushes down the deflection coil A remaining on the winding jig 5 side.

The fallen deflection coil A falls onto the discharge conveyor 200 through the opening 81 of the machine base L, and can be re-driven in forward and reverse directions to be distributed to the left or right depending on which side of the two winding jig units 56 it was formed on. The conveyor 201 divides the distribution into left and right. Although not shown, this deflection coil discharge section is also provided with means for removing defective products due to disconnection or short circuits.

After removing the deflection coil A from the winding jig 5, the moving board 1
11 is moved forward again as shown by the arrow in FIG. 21, and the winding jig 6 is assembled to the winding jig 5 in a butt state. Thereafter, the jig holding part 114 is rotated as shown by the arrow mark M in FIG. Excision part 114
a are facing each other, and the holding on the winding jig 6 between the upper and lower jig holding parts 114 is released.

Next, the moving board 111 is retreated as shown by the arrow mark and returns to the original position. At this time, the bell crank 10 is released from the push by the Fukasaku rod 11B and becomes free, and the spring 11 exerted on itself and the spring 8 acting on the lock pin 7
Due to the bias, the lock pin 7 fits into the horizontal hole 6b of the protrusion 6a of the winding jig 6 inserted into the winding jig 5, and the winding jig 5.6 is brought into the connected state only by the spring pressure. In this locked state, the winding jig unit 56 at the lower stop position completes the work of forming and taking out the deflection coil 56, and is moved from the lower stop position to the upper stop position by the rotation of the rotating holder 3. Next, it is subjected to a winding operation for forming a deflection coil form.

Thereafter, by repeating the above operations, the winding jig unit 56 at the upper stop position forms a deflection coil form by winding, and the winding jig unit 56 at the lower stop position forms a deflection coil formed by winding. The operations of forming the deflection coil by integrating the wire into the coil form are performed successively in parallel.

``The present invention is not limited to the embodiments described above, and can be implemented in various ways. For example, the heating and integration of the wire rod does not require energization of the wire rod, but can be heated by a member in contact with the deflection coil form. You may.

Effects of the Invention According to the present invention, a pair of winding jigs forming a deflection coil are held cantilevered by only one of the winding jig sides as a removably connected winding jig unit, Since it is stably supported so that it can be integrally driven, the support and rotational drive structure around the pair of winding jigs can be simplified. In addition, it is possible to move the winding jig and share the work of forming the deflection coil at different positions simultaneously without making the device particularly large or complicated. Furthermore, since the pair of unitized winding jigs can be attached and detached as necessary by the attachment and detachment means,
The formation and removal of the deflection coils can be carried out in the same manner as in the case of individual support.
