Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of assembling a motor with a terminal board, and more particularly to a method of assembling a motor with a terminal board using a rigid circuit board having terminals for winding the ends of the coil.

Figures 1 and 2 are diagrams explaining the method of assembling a conventional small cylindrical brushless motor, which is the starting point of the present invention, and Figure 1 shows a perspective view of a bobbin having a rotating shaft. , @2 is an exploded perspective view of the end of the motor.

In FIGS. 1 and 2, a cylindrical bobbin 10 has a pair of hoses 16 at both ends and six ribs 12 on the side surface (substantially parallel to the rotation axis 18). Both ends of the rib 12 are connected to the bobbin 10
stands out from The hobbin lO is further located at a position extending from the midpoint of the adjacent ribs 12 toward the rotation Ik1118 side.
It has a plurality of ends j' and pins 14 for binding. Note that a Mizuhisa magnet (1δ) is added to the rotating shaft 18. First, a conductive wire is wound using any adjacent rib 12 as a winding frame to form a coil 20 (see FIG. 2), and then the terminal of the coil is tied to the terminal pin 14. This operation is repeated to form six coils. The hobbin lO around which the coil 20 is wound is placed in a cylindrical case 22, as shown in FIG.
After passing the terminal pin 14 through the hole 26 of the cover (side plate) 24, the wire is unwound from the pin 14 and its end 28 is soldered to the conductive foil 3o.

By the way, in the conventional example mentioned above, as a structural problem,
(d) Since the surface of the winding around the rib 12 and the mJ of winding the end of the coil around the ☆1ζr-bin 14 are about 90°W, the winding device requires a special 1-layer (7, the device is complicated). (b) In small vari motors, the terminal pins 14 are extremely thin (for example, 1 m in diameter) and are expensive.
m) IF, the terminal pin 14 may break during the process of twisting or untying the coil end; (c) the terminal pin 14 may be damaged;
Since the spacing between the terminal pin 16 and the terminal pin 16 is narrow (for example, 0.95 mm), it is easy to get rid of the ends of the coil.
It is a special group or spirit that covers the body. On the other hand, the problem with the above-mentioned conventional example is that (a) the terminal pin 14 with the end of the coil wound must be manually unraveled after passing through the terminal pin 14 through the side &24.
(b) Since the area of 4' @ foil 3o is narrow and close together, it is extremely difficult to solder, especially for small motors, and (C) It is necessary to newly connect the motor circuit and external circuit. There is a problem in that the conductive foil 30 must be soldered.

An object of the present invention is to use a rigid circuit board provided with a barbed terminal, eliminate the need for a terminal pin for the barbed wire that was attached to a conventional bobbin, and solve the above-mentioned problems. An object of the present invention is to provide a method 7) 4 for assembling a motor with a removed circuit board.

Another object of the present invention is to provide a method of assembling a motor with a circuit board similar to the object described in item 1 above, using a rigid circuit board having external circuit connections as well as barbed terminals.

Summary of the Invention The present invention relates to a method of assembling a motor by winding a core wire around a plurality of ribs provided on the side surface of a hobbin. A rigid circuit board having a plurality of terminals for winding the coil end and a motor circuit is prepared, (a) an extension of the shaft of the hobbin marked H - and the above circuit board is placed at a distance from the hobbin marked L. (b) Using a winding device, wind a conductive wire around the adjacent ribs of the hobbin No. 42 to form a coil; (C) Next, connect the winding device No. 1 with the bobbin No. L and the circuit board. Change the relative position j position and turn the end of the coil into 1-end r-;
(d) f: Repeat steps (b) and (C) to complete the winding of the conductor around the ribs and terminals, and (e
1) A method for assembling a terminal holder, characterized in that the circuit board L is fixed to the end of the hobbin.

As described in detail, the present invention has the following effects.

(1) Since the collar terminal has approximately one square angle with respect to the rotation axis of the motor, the plane of rotation for winding the conductor around the bobbin and for winding the end of the coil around the collar terminal is the same. Therefore, simply by changing the relative positions of the flyer for winding the conductor, the bobbin, and the circuit board, the coil can be wound and the ends of the coil can be tied off, thereby improving one work efficiency.

(2) Since a conductive pattern is provided on the circuit board, the connection of the motor circuit is completed by twisting and soldering the end of the coil to the hook terminal. Compared to the conventional example, the number of motor assembly steps is reduced and the work is easier.

(3) Connection to an external circuit can be made by simply soldering the end of the coil to the Karage terminal, so the number of motors produced can be reduced by one half.

(4) Since the terminal pins conventionally provided at the ends of the bobbin can be omitted, the coil winding work becomes easier and the bobbin assembly is advantageous. Furthermore, the manufacturing cost of the bobbin can be reduced.

Although the present invention has been described in detail, it is clear that various modifications and changes can be made based on the embodiments described above. For example, in the explanation of FIGS. 4 and 5, the slide base 58 is moved, but the flyer 60 may be moved with the slide base 58 fixed. Furthermore, it goes without saying that the shape of the conductive pattern (motor circuit) on the rigid circuit board is not limited to the embodiment. Furthermore, the number of terminals on the circuit board may be changed depending on the type of motor/coil connection.
