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 rotated around the wire rod 1, thereby attaching the tip of the wire rod 1, which will become the starting end of the coil, to the winding start terminal pin 4, and then
When the bobbin 3 is rotated while the nozzle 5 is fed along the body of the bobbin 3, the wire 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 end-of-winding terminal 6 of the bobbin 3 a predetermined number of times, the wire 1 is attached to the end-of-winding 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 with a cutter 7 or the like.

"Problems to be Solved by the Invention" However, when the wire 1 is attached to the terminal pin 4 for starting winding of the bobbin 3 in the above-mentioned conventional winding method, as shown in FIG. The wire rod 1 crosses from the tip to the body of the bobbin 3,
This part of the wire is the terminal pin 4 for starting winding and the bobbin 3.
In order to float the winding start terminal pin 4 with a certain distance between it and the wall part, the wire rod 1 is attached to the winding start terminal pin 4 in the next step in order to apply solder to the winding start terminal pin 4. 4 is immersed in a solder bath, the solder rises along the wire 1 from the tip of the winding start terminal pin 4 to the body of the bobbin 3,
There is also the problem of inadvertently adhering solder to the coil wound around the body of the device. Furthermore, since the wire 1 extending from the tip 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 it is easy to cut due to unintentional load being applied. 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 lashed, the folded portion of the wire 1 crosses at the tip of the terminal pin 4 for winding start, so this portion bulges out from the other rabbeted portions. As a result, when the terminal pin 4 for starting winding is immersed in the solder bath in the solder filling process, molten solder is applied to the beginning of winding due to the bulge of the barbed wire 1 at the tip of the terminal pin 4 for starting winding. There is a problem in that the terminal pins 4 are prevented from crossing over the barbed wire rods 1 on the base end side, resulting in insufficient solder application.

When the wire rods 1 of the winding start terminal pin 4 and the winding end terminal pin 6 are tied together, as shown in FIG. 5, especially when winding the coil around the transformer,
When a wire rod 1 having a large diameter or being hard is used, a large load is applied to the winding start terminal pin 4 and the winding end terminal pin 6, causing problems such as bending.

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. To provide a method and device for winding a coil onto a bobbin with a terminal pin, which does not cause the terminal pin to bend due to a large load.

The nozzle has an insertion hole extending from the base end to the tip for inserting the wire, and a receiving hole of a predetermined depth into which the terminal pin of the bobbin fits into the tip. Align the tips of the nozzles and each other, insert the wire from the base end of the winding end nozzle into each insertion hole of the winding end nozzle and the winding start nozzle, and pull it out from the base end of the winding start nozzle. After that, remove the winding end nozzle from the winding start nozzle.
While keeping the wire passed through each insertion hole, pull it apart, then fit the receiving hole of the winding start nozzle into the winding start terminal pin of the bobbin, and start winding around the winding start terminal pin. After rotating the nozzle for winding and attaching the wire to the terminal pin for starting winding of the bobbin, remove the wire and the terminal pin for starting winding of the bobbin from the nozzle for starting winding, and further rotate the bobbin to finish winding. The wire rod fed out from the winding nozzle is wound around the body of the bobbin by a predetermined number of turns, and then the end-of-winding terminal pin of the bobbin is inserted into the receiving hole of the end-of-winding nozzle. This method is characterized by a method of winding a coil into a bobbin coil with a terminal pin, which is formed by rotating an end-of-winding nozzle and attaching a wire to the end-of-winding terminal pin.

As shown in FIG. 13, the plunger solenoid 42 is used to separate the feed rollers 38 and 39 from each other in advance against the elastic biasing force of the spring 41, thereby preventing the rotation of the bobbin 34 from affecting its body. Due to the winding force of the wire A, the wire A is unwound from the wire feed nozzle 36 and winding end nozzle 26 by a raw wire spool (not shown). After winding the body of the bobbin 34 by a predetermined number of turns, the main control mechanism 10
After moving the nozzle drive base 11 and positioning the winding end nozzle 26 above the winding end terminal pin 34b of the bobbin 34, the main control mechanism 10 controls the nozzle drive base 11 as shown in FIG.
