Description

[Detailed description of the invention] (Industrial application field) The present invention is designed to automatically remove coil bobbins from one process to the next in the process of winding coil bobbins. The present invention relates to a bobbin attitude changing structure capable of changing the attitude of a coil bobbin during movement when the direction of the coil bobbin needs to be changed as the processing location moves.

(Prior Art) In the coil bobbin processing process, for example, if the shape of the coil bobbin is as shown in 1 in Fig. 2, taping is performed on the coil layer of the coil bobbin after winding, and then the coil terminal is When performing taping, such as when moving on to soldering, it is most efficient to wrap the tape while rotating the bobbin with the bobbin axis horizontal and the coil terminal pins outward.

On the other hand, when soldering terminal pins, both flux dipping and soldering processes require the terminals to be directed toward a flux liquid bath or molten solder bath, and the coil terminal pins must be directed downward.

Therefore, in the conventional case, after completing the taping process, a worker or a robot discharges the coil bobbin from the taping device and supplies it to the soldering device.

(Problem to be solved by the invention) As mentioned above, in the conventional method, when it is necessary to change the posture of the coil bobbin during the transition from one process to the next in the winding process, it is necessary to change the position of the coil bobbin each time. Since the direction of the bobbin is changed and delivered by a worker or a robot, there is a problem in that it takes too much time to move the bobbin between processes.

The purpose of this invention is to solve these problems and
Drives the winding jig that supports the coil bobbin,
To provide a bobbin attitude changing structure capable of automatically changing the attitude of a coil bobbin while the bobbin moves along a linear course.

They are shown superimposed on the same drawing.

As shown in the lower right corner of the figure, the coil terminal pin 1a of the coil bobbin 1 was initially oriented horizontally.
While the head 21 moves along the inclination of the bobbin attitude changing bar 11, it gradually turns downward, and at the end of the inclination, the coil terminal pin 1a points straight down.

In this way, the orientation of the bobbin can be changed 90 degrees from horizontal outward to straight down.

Next, an example of use of this embodiment will be described.

FIG. 6 is a simplified plan view of an example in which the embodiment of the present invention is used for winding finishing.

The upper part 6 of the movable table in the center of the figure is located in the left and right direction of the arrow X in the figure, and
It can move in the direction of arrow Y, and is driven by a motor built into the lower part of the moving table. Attached to the left and right sides of the upper part of the movable body are swing arms 7a and 7b that can rotate 180 degrees about shafts 7c and 7c and can change the positions of their tips.

Each operation is automatically performed for the coil bobbin that has been moved previously.

All of the operations of these winding finishing devices, the upper part 6 of the moving table, and the winding arms 7a, 7b are controlled by an electronic control device (not shown) containing a built-in computer. .

Among these series of winding finishing devices, the taping device 42 is designed to connect the axis of the coil bobbin to the horizontal coil terminal pin 1a in order to increase its work efficiency.
It is desirable to wind the exterior tape while rotating the bobbin with the bobbin facing outward. On the other hand, for the flux dipping mechanism 44 for soldering, the flux tank of the soldering device 45, and the molten solder tank, it is necessary to keep the bobbin 1 facing downward so that the coil terminal pin 1a protrudes lower than the other parts. be.

Therefore, in order to change the posture by turning bobbin 1 90 degrees,
The bobbin attitude changing structure shown in FIG. 1 is inserted between the taping device 42 and the flux dipping mechanism 44.

Further, the bobbin 1 that has completed the work of the continuity test or resistance test device 46 remains facing downward, but the bobbin 1 that has been moved from the guide rail 5a onto the guide rail 5b by the winding arm 7b is moved to the winding arm 7b.
Since the bobbin is turned 180 degrees, the bobbin is facing upward.

However, the following defective product discharge mechanism 48 and
