Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method and apparatus for winding a coil onto a bobbin with terminal pins.

``Prior Art'' Conventionally, when winding a coil around a bobbin equipped with a terminal pin, as shown in FIG. 4, the nozzle 5 is made to revolve around the bobbin 3, thereby attaching the tip of the wire 1, which will become the starting end of the coil, to the terminal pin 4 for starting the winding. When the bobbin 3 is rotated, the wire rod 1 is fed out from the nozzle 5 and wound around the body of the bobbin 3 by a predetermined number of turns. Thereafter, in the same manner as described above, by making the nozzle 5 go around the winding end terminal pin 6 of the bobbin 3 a predetermined number of times, the wire rod 1 is attached to the winding end terminal pin 6. The crossover wire of the wire rod 1 attached to the winding start terminal pin 4 and the winding end terminal pin 6 is cut by a cutter 7 or the like.

"Problems to be Solved by the Invention" However, in the above-mentioned conventional wire winding method, when the wire rod 1 is attached to the winding start terminal pin 4 of the bobbin 3, as shown in FIG. The wire rod 1 crosses from the tip to the body of the bobbin 3, and the wire rod in this part floats up with a certain gap between the terminal pin 4 for winding start and the wall of the bobbin 3, so that the wire rod is removed in the next step. When the terminal pin 4 for starting winding 4 is immersed in a solder bath in order to apply solder to the terminal pin 4 for starting winding to which the terminal pin 1 is attached, the body of the bobbin 3 is removed from the tip of the terminal pin 4 for starting winding. There is a problem in that the solder rises along the wire rod 1 that crosses toward the bobbin 3, and the solder also inadvertently adheres to the coil wound around the body of the bobbin 3. Furthermore, since the wire rod 1 extending from the end of the terminal pin 4 for winding start to the body of the bobbin 3 is lifted from the bobbin 3 as described above, there is also a problem that an unexpected load is applied and the wire rod 1 is easily cut. In order to prevent the wire 1 that extends from the tip of the terminal pin 4 for starting winding to the body of the bobbin 3 from floating up from the bobbin 3, the wire 1 is folded back and stacked from the tip of the terminal pin 4 for starting winding toward the base end. Even when the wire is barbed, since the folded portion of the wire 1 crosses at the tip of the terminal pin 4 for winding start, this portion bulges out from other portions when the wire is barbed.

As a result, when the terminal pin 4 for starting winding is immersed in the solder bath in the solder filling process, the bulging bulge at the tip of the terminal pin 4 for starting winding is due to the wire 1, so that the molten solder is not rolled. There is a problem in that the barring on the proximal end side of the starting terminal pin 4 is prevented from reaching the wire 1, resulting in insufficient solder application.

In addition, when attaching the wire 1 to the winding start terminal pin 4 and the winding end terminal pin 6, as shown in FIG. When winding a coil such as a transformer, especially when winding a coil such as a transformer, if a thick or hard wire material 1 is used, the terminal pin 4 for the start of winding and the terminal pin 6 for the end of winding may be used.
There were also problems such as bending due to the heavy load applied to it.

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention has been devised so that when automatically winding a wire, when attaching a wire to each terminal pin of a bobbin, the bobbin is connected from the base end of the terminal pin without having to be folded back and tied twice. The wire rod can be passed toward the body, eliminating various problems that occur in the past due to the crossover wire part lifting up from the bobbin.Also, even if the wire rod is thick or hard, it will not work properly.

The winding end nozzle 26 has a timing pulley 27 on its upper part, and a timing belt 30 is wound between the timing pulley 27 and a timing pulley 29 provided on the output shaft of a pulse motor 28. The pulse motor 28 is
It is fixedly attached to the nozzle base 23 via a metal fitting 31. The winding end nozzle 26 has an insertion hole 33 extending from the proximal end to the distal end for passing the wire through, and a predetermined depth provided at the distal end into which each terminal pin 34a to 34d of the bobbin 34 is inserted.

On the other hand, a wire feed nozzle 36 is disposed above the winding end nozzle 26 which is in an upright position.

The wire feed nozzle 36 has a nozzle hole 37 through which the wire is inserted.
The feed rollers 38 and 39 are shown facing.

The feed roller 38 is driven by the motor 4o, and this drive causes the feed roller 39 to follow and rotate, thereby feeding out the wire from the nozzle hole 37. The feed roller 39 has its rotating shaft elastically biased by a spring 41 in a direction to sandwich the wire between it and the feed roller 38. Moreover, the plunger solenoid 42 presses the rotating shaft of the feed roller 39 against the elastic bias of the spring 41, so that the wire can be released from being held between the feed roller 38 and the feed roller 38. Above wire feed nozzle 3
6 and feed rollers 3B and 39 are mounted on a movable base 43. The motor 40 and plunger solenoid 42 are also mounted within the movable base 43. The movable table 43 is moved by a rod 45 by an air cylinder 44.

It is also possible to fit the lower part of the nozzle hole 37 and the insertion hole 33 so that the nozzle hole 37 and the insertion hole 33 are well aligned. The rod 45 is supported by a support member 47 on the nozzle drive base 11 via a thrust bearing 46 so as to be vertically movable. The air cylinder 44 is attached to the nozzle drive base 11 via a metal fitting or the like. A guide roller 4 is provided between the wire feeding nozzle 36 and the winding end nozzle 26.

An air cylinder 69 attached to one of the supporting members 63 is connected to the sliding member 67, and the air cylinder 69 moves the movable base 56. In addition, the winding start nozzle 49 can be moved up and down, and this is used as a vertical movement mechanism 90. The winding start nozzle 49 has a drum 70, and a shoe 72 is pressed against the drum 70 by the elastic force of a spring 71 to prevent the winding start nozzle 49 from rotating inadvertently. A support rod 74 protruding from the rear of the shoe 72 is slidably inserted into a through hole 75 of a support 73. The support 73 is fixed to the L-shaped arm 55.

It can rotate together with the shaft 78. The rotating shaft 78 is rotatably supported on a plate 80 and has a timing pulley 81 at its upper end, with a timing belt 84 between the timing pulley 81 and a timing boot 1183 provided on the output shaft of the pulse motor 82. Let's hang it around. The pulse motor 82 is fixedly attached to the plate 80 via a member 85.

For attachment, the plate 80 is fixed to the nozzle drive base 11 via a pedestal 86. The mechanism leading from the pulse motor 82 to the coupling protrusion 76 is a winding start nozzle 490 rotating mechanism 88. As for mounting, the plate 80 can be directly fixed to the movable base 56 without being fixed to the nozzle drive base 11 using the pedestal 86, as shown by the two-dot chain line in FIG. 4. In this case, the coupling member 77 may simply be fixed to the lower end of the rotating shaft 78. It goes without saying that the bobbin 34 is removably attached to a spindle 87 whose rotation is controlled as in the conventional case, and terminal pins 34a and 34c for the start of winding and terminal pins 34c for the end of winding to which the starting and ending ends of the coil are attached. There are terminal pins 34b and 34d. The number of terminal pins 34a to 34d corresponds to the number of layers to be wound around the bobbin 34.

Next, the method of winding a coil onto a bobbin with a terminal pin will be explained.
The L-shaped arm 55 is rotated via the rack 59 and pinion 58 to turn the winding start nozzle 49 into an upside-down shape with the tip facing upward, and the movable base 56 is moved by the escape mechanism 89, that is, by the air cylinder 68. is moved in the left-right direction, and the tip of the winding start nozzle 49 is brought into contact with the tip of the winding end nozzle 26, as shown in FIG.

Thereafter, the air cylinder 44 is moved back to move the wire rod feed nozzle 36 upward, thereby moving the wire rod feed nozzle 36 to the winding end nozzle 2.
Separate from the proximal end of 6. Next, as shown in FIG. 6, the winding end nozzle 26 is rotated from 45 degrees to 90 degrees
Roll over only once. That is, the nozzle base 23 is rotated by the air cylinder 22 via the rotary plate 19, and the end-of-winding nozzle 26 is turned sideways by 45 degrees to 90 degrees as described above. Reduces the resistance to engagement. Next, as shown in FIGS. 4 and 7, the escape mechanism 89 separates the winding start nozzle 49 from the winding end nozzle 26 while keeping it standing upside down. At this time, the wire A is drawn out from the insertion hole 33 of the winding end nozzle 26 due to the engagement resistance with the tip of the winding start nozzle 49, and the winding start nozzle 49 passes through the winding end nozzle 2.
Move away from 6. Then, as shown in FIG. 8, after the winding start nozzle 49 is reversed into an upright position by the reversing mechanism 65, the nozzle driving base 11 is moved back and forth and left and right by the insect bite mechanism 10, as shown in FIG. Winding start nozzle 49
is positioned above the winding start terminal pin 34a of the bobbin 34 mounted on the spindle 87. Next, as shown in FIGS. 10 and 19, the main control mechanism 10 moves the nozzle drive base 11 downward to fit the receiving hole 51 of the winding start nozzle 49 into the winding start terminal pin 34a of the bobbin 34. While the rotation mechanism 88 rotates the winding start nozzle 49 through the coupling protrusion 76 and the coupling groove 52, the main control mechanism 10 causes the winding start nozzle 49 to be tangled through the nozzle drive base 11. Move it up according to the pitch. Therefore, the winding start nozzle 49 moves up while rotating around the winding start terminal pin 34a of the bobbin 34, so that the wire A inserted into the insertion hole 50 of the traverse winding start nozzle 49 is used for winding start. It sticks to the terminal pin 34a. After a predetermined number of turns of the wire A are attached to the terminal pin 34a for winding start, as shown in FIG. Connect the hole 51 to the terminal pin 34a for starting winding.

Move it to the winding start position. Next, as shown in FIG. 14, the main control mechanism 10 moves the winding end nozzle 26 along the axial direction of the body of the bobbin 34 while rotating the bobbin 34 together with the spindle 87 a predetermined number of times. At this time, as shown in FIG. 13, the plunger solenoid 42 resists the elastic biasing force of the spring 41, and
39 are spaced apart from each other, so that the bobbin 34
Due to the winding force of the wire rod A around the body due to the rotation of the

After positioning it above the pin 34b, as shown in FIG. 16, the main control mechanism 10 moves the nozzle drive base 11 downward, and the receiving hole 35 of the end-of-winding nozzle 26 is connected to the end-of-winding terminal pin of the bobbin 34. 34b, and while the pulse motor 28 rotates the end-of-winding nozzle 26, the main control mechanism 10 raises the end-of-winding nozzle 26 according to the barbed pitch. 49, the wire rod A inserted into the insertion hole 33 of the end-of-winding nozzle 26 is barbed a predetermined number of times to the terminal pin 34b for the end of winding, and the wire rod A is inserted into the insertion hole 33 of the end-of-winding nozzle 26, and the wire rod A is barbed a predetermined number of times, and the wire rod A is inserted into the insertion hole 33 of the end-of-winding nozzle 26. Cut the line. Thereafter, the nozzle drive base 11 is moved upward by the main side '4B mechanism 10, and as shown in FIG. 17, the receiving hole 35 of the end-of-winding nozzle 26 is pulled out from the end-of-winding terminal pin 34b.
