Reference numeral 14 is for accurately indexing the predetermined coil holder 12 of FIG. 1 into the winding device 7.

Next, the mounting means 19 will be described with reference to FIG. The mounting unit 19 is a device for inserting or mounting the coil C, which is detachably set in the buffer unit 11, at a predetermined position of the substrate 17. The motor 13a and the tool changer 14 are connected to the motor M along the X guide portion 16a.
It is possible to move in the arrow X direction by driving 1. Also,
The motor 13a, the tool changer 14, and the X guide portion 16a can be moved in the arrow Y direction by driving the motor M2 along the Y guide portion 16b.

A tool changer 14 is set on the shaft of the motor 13a. By driving this motor 13a, the tool changer 14 can be moved up and down in the arrow Z direction. In this way, the X guide portion 16a, the Y guide portion 16b, and the motor 13a constitute an XYZ unit 16 for moving the tool changer 14 in the X, Y, and Z directions orthogonal to each other.

When the board 17 is conveyed to the position corresponding to, the coil C is moved from the buffer means 11 side to the board 17 side by the insertion head 13a, and the coil C is inserted and attached at a predetermined position of the board 17. It is like this. The above-described motors M1, M2, M3, the motor 13a, etc. are designed so that drive commands are issued by the CPU 300 of the operation panel OP.

Next, an operation example in the above embodiment will be described. First, the wire rod bobbin 3 is moved by the wire rod feeding unit 99 shown in FIG.
A wire rod W, which is also called a wire, is pulled out from. This wire rod W
Passes through the peeling unit 6 with proper tension applied by the tensioner 5 in FIG. This peeling unit 6
By passing through, the insulating coating of the required soldering portion of the wire W is peeled off.

On the other hand, as illustrated in FIG. 2, the winding position WP
The winding means 24, which is also referred to as one winding jig, is indexed. Then, the slider 134 moves forward and the moving body 46 moves from the index disc 25 side to the index disc 25 side against the force of the spring 46a. For this reason, the pressing means 44 of the winding means 24, the base portion 48 and the winding shaft 42b are projected from the hole 51b of the index disc 25. Also, the couplings 52, 54
Are connected. Moreover, as shown in FIG.
The pressing means 44 is held in a state of being separated from the winding shaft 42b.

The wire W is, as shown in FIG. 8, a roller 6a.
Through the wire rod feeding portion 99 and the nozzle 86, and further between the cutter 94. The winding start end W1 of the wire W passes between the winding shaft 42b and the pressing means 44, and when the length of the winding start end W1 reaches a predetermined lead length L1, the wire W is fed by the wire feeding portion 99. The feeding stops.

When the pressing means 44 returns, the wire W is reliably sandwiched between the pressing means 44 and the winding shaft 42b. In this case, the wire W is not clamped by the clamp 90.

Next, as shown in FIGS. 8 to 9, the wire W
Roll up. That is, as shown in FIG.
180 ° in the R direction. As a result, the winding start end W1 of the wire W faces upward as shown in FIG. Subsequently, by moving the nozzle member 84 of FIG. 8 to the Y1 side in the arrow Y direction, the base member 48 is rotated in the R direction by a predetermined number of turns while moving the wire W in the Y1 direction at a predetermined winding interval. I will do it.

As a result, the normal coil C having a predetermined number of turns is formed on the winding shaft 42b. The coil C thus formed can be a closely wound coil, a coil wound at a predetermined interval, or a coil having a predetermined interval at a necessary portion.

Next, in the state shown in FIG. 10, the cutter 9
Adjust the position of 4 in the height direction. As a result, the coil C
The lead length L of the winding end end W2 is set to a predetermined length and cutting is performed. The lead length L1 of the winding start end W1 can be set in advance in the state of FIG.

Next, as shown in FIG.
8 is rotated 180 ° in the R direction from the state of FIG. As a result, as shown in FIG. 11, the winding start end W1 and the winding end end W2 face downward.

In this state, the coil has a normal coil C shape as shown in FIG. That is, the winding start end W1
The winding end end W2 is substantially parallel to the coil C with the diameter separated.

However, if necessary, it is possible to form a coil C different from the shape of the normal coil C as shown in FIGS. 15 and 16. That is, this coil C is a so-called center forming type coil,
It can be formed using the forming members 100, 100. The forming members 100, 100 are formed laterally closer to the winding start end W1 and the winding end end W2 of the coil C. After this forming, the forming members 100, 100 are separated from the coil C as shown in FIG.

After forming the ordinary coil C or the center forming type coil C in this manner, as shown in FIG. 11, the cylinder 70 is operated to release the pressing means 44 from the winding shaft 42b. The normal coil C or the center forming type coil C is set in a state in which it can be removed from the winding shaft 42b.

As shown in FIG. 12, the coil C released from the pressing means 44 and in the free state is extracted from the winding shaft 42b. The extraction member 94 is used for this extraction.
When the extraction member 94 is brought close to the coil C, the coil C is engaged with the coil C as shown in FIG. 13, and the extraction member 94 is moved in the Y1 direction of the Y direction, that is, in the axial direction of the winding shaft 42b. Pull out.

The completed normal coil C or center forming type coil C is, as shown in FIG.
The coil holder 12 of the buffer means 11 is clamped. That is, by extending the cylinder 113, the winding start end W1 and the winding end end W2 of the coil C are sandwiched between the base 118 and the clamp member 116. Then, by contracting the cylinder 113, the winding start end W1 and the winding end W2 are completely sandwiched and fixed by the force of the spring 110 between the base 118 and the clamp member 116.

In this way, the coils C are sequentially held by the coil holders 12 of the rotary table T shown in FIG.

An insertion head 13 is mounted on the tool changer 14 of the drive unit shown in FIG. By moving the insertion head 13 in the X direction, the Y direction and the Z direction, the normal coil C or the center forming type coil C is moved to a predetermined position on the substrate 17. Then, the insertion head 13 moves in the Z direction orthogonal to the X direction and the Y direction, that is, moves downward to mount one or a plurality of coils C on the substrate 17.

The coil mounted on the board 17 is mounted and soldered in the state as shown in FIG. That is, the coil C is fitted into the hole 17b of the board 17 and the solder 1
It is soldered by 7a. In this way, the required coil C can be mounted at a predetermined position on the board 17.

By the way, in a preferred embodiment, the winding shafts 42a, 42 of the winding means 22, 24, 26, 28 shown in FIG.
Since b, 42c, and 42d have different thicknesses, coils having different inner diameters can be wound. Further, in each winding means, the number of windings can be sequentially changed as needed based on a command from the operation panel OP of FIG.

Further, different coils can be wound by changing the diameter or type of the wire material W to be fed. Then, a specific coil can be wound in a state where any one of the winding means 22, 24, 26, 28 is indexed to the winding position WP. The wound coil can be mounted at a predetermined position on the substrate 17 by the mounting means 19 via the buffer means 11.

In addition, in FIG. 2, when indexing one of the winding means 22, 26, 28 different from the winding means 24, the slider 134 is moved backward to connect the couplings 52, 54. Needless to say, the indexing motor 29 can be driven to remove the winding means 22 from the winding position WP, for example.

Next, refer to FIG. This Figure 19
3 shows another embodiment of the winding device 7 shown in FIG. 2 of the present invention. The winding device 7 includes a plurality of winding jigs 224, 226, 22.
Have eight. These winding jigs 224, 226, 22
8 have separate bobbins 203, 204, 205, respectively.
Are provided correspondingly. And these bobbins 2
03, 204, 205 have different wire rods W3, W4, W5
Is wrapped around each.

Therefore, each winding jig 224, 226, 228
The different wire rods W3, W4 and W5 can be wound as coils. Therefore, each winding jig 224, 226,
A coil can be made at 228 with wires of different thickness. Each winding means 224, 226, 228
The thickness of the winding shaft may be the same or different.

By doing so, it becomes easy to mount different types of coils on different types of substrates. That is, in the embodiment shown in FIGS. 1 and 2, when changing the thickness of the wire W, the bobbin must be replaced with another bobbin, but this is not necessary in the embodiment of FIG. Therefore, in one coil assembling apparatus, it is easy to mount different types of coils corresponding to different types of substrates, that is, to switch the model of so-called electric equipment.

Next, reference will be made to FIG. The assembly device group shown in FIG. 20 shows an example in which a plurality or a plurality of, for example, 20 or more of the coil assembly devices 1 shown in FIG. 1 are arranged and set. In other words, this assembly device group is an inline assembly of a plurality of assembly devices 1 corresponding to the types of coils to be mounted on the board. For example 20
If you want to attach several kinds of coils to the board,
There are 0 or more types of assembling devices 1. The coil assembly device 1 can be operated by the operation panel OP.
By arranging the plurality of or a large number of coil assembling apparatuses 1 in this manner, the following merits are obtained.

In general, more than 20 types of coils are often mounted on the substrate of electric equipment such as high frequency. For this reason, it is possible to make different types of coils in the coil assembling apparatus 1 of FIG. 20 and sequentially mount, for example, 20 types of coils on each substrate.

Even if a coil having 20 or more wire diameters is mounted on a certain board, if the combination of the 20 or more wire diameters is the same on another board, the insertion order of the coil can be changed. Of course, the program on the operation panel OP may be changed according to the change of the order.

At this time, the buffer means 11 as the intermediate buffer unit can be used to improve the operating rate of this system when it is in-line. That is, the variation in the time required for the winding device 7 and the time required for the mounting means 19 in each assembling device 1 is absorbed.

The present invention is not limited to the above embodiment. For example, in FIG. 2, four winding devices 22, 2
Although 4, 26 and 28 are used, the number of winding devices is not limited to four, and two or three winding devices or five or more winding devices may be provided. In addition, in FIG. 2, four winding devices are set between the index disks 23 and 25, and one winding device is positioned at the winding position WP by rotational indexing.

However, the present invention is not limited to this, and a plurality of winding devices may be arranged linearly and one of them may be positioned at the winding position WP.

As described above, according to the first aspect of the present invention, it is possible to make separate coils in a plurality of coil winding means and position them with respect to a mounting object such as a substrate. For this reason, it is very time-saving and easy to apply when it is necessary to mount various types of coils. Further, according to the invention of claim 2, by arranging each coil winding means in a circular shape,
Space saving can be achieved. Further, according to the invention of claim 3, when winding the coil, the coil can be surely and easily wound around the winding member. According to the invention of claim 4, an appropriate coil can be wound at a predetermined timing when the wire is wound into a coil. Then, the winding end can be cut by a cutting means to form a coil. Further, according to the invention of claim 5, the gap between the winding time of the coil and the time required for mounting the coil on the object can be absorbed by the cushioning means. Therefore, the work can be easily adjusted and the coil can be efficiently formed and mounted.
