Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a winding machine for winding a coil bobbin or the like, winding a terminal, and performing terminal treatment.

[0002]

[Prior art]

 Conventionally, in this type of winding machine, as shown in FIG. 8, for example, a Z-axis moving table 43 1 which moves up and down along guides 42 provided on the left and right side surfaces of the winding machine main body 41 is attached. A nozzle 44 for guiding and winding the winding terminal to the bobbin terminal is supported on the Z-axis moving base 43, and a peeling mechanism 45 for moving in the X-axis and Y-axis directions is attached to the main body 41. It is known that a winding cutting mechanism 47 is attached to the side where the spindle tip 46 is exposed through a cutting mechanism attaching plate, and the main body 41, the twisting mechanism 45, and the winding cutting mechanism 47 are integrated. The winding cutting mechanism 47 is a line that supports the winding end and applies tension in the X-axis direction to cut it, and then releases the cutting line by supporting the cutting end and rotating it downward around the X-axis. It is configured to support the sandwich and move in the cutting direction. Reference numeral 48 is an X-axis moving base, 49 is a Y-axis moving base, 50 is a Z-axis moving base drive motor, 51 is an X-axis moving base drive motor, and 52 is a Y-axis moving base drive motor.

Such a configuration has a problem in terms of accuracy of the machine itself. That is, if the tangling mechanism is freely movable in the three-dimensional directions of the X axis, the Y axis, and the Z axis, and the nozzle 44, which is the point of action of the tangling mechanism, must be accurately driven with the preset accuracy. However, since the Z-axis moving base 43 that serves as the Z-axis reference is provided along the guide rails 42 provided on both side surfaces of the main body 41, the dimensional accuracy of both side surfaces must be strict. However, since the main body 41 is usually formed by casting, distortion and deviation are likely to occur after the cutting process, and the Z-axis reference is distorted, resulting in an error at the tip of the nozzle 44.

Further, since the Z-axis reference surface is the both side surfaces of the main body 41, the machine tool for processing the main body 41 becomes large. Naturally, the accuracy of a large machine tool deteriorates, which eventually results in an error at the nozzle tip.

Further, the Z-axis moving base 43 is heavier and heavier than the main body 41, and the weight as a whole is increased. As a result, a large drive source must be adopted, resulting in noise and vibration accompanying the drive.

[0006]

[Problems to be solved by the device]

 In view of this point, the present invention makes it easy to machine the X-axis, Y-axis, and Z-axis moving table with a small machine tool, and reduces the weight of the entire moving table, thereby improving the weight and dimensional accuracy of the nozzle tip. Its main purpose is to improve the position accuracy, to propose a winding machine that is easy to assemble, small, and inexpensive.

[0007]

[Means for Solving the Problems]

 The present invention is equipped with an X-axis moving base that moves in the left-right direction along a guide provided on the upper surface of the winding machine body, and moves in the front-back direction along a guide provided on the upper surface of the X-axis moving base. Attach the base, and further mount the Z-axis moving base that moves up and down along the guide provided on the front side of the Y-axis moving base, guide the wire rod to the Z-axis moving base, wind the wire on the bobbin, and twist the terminals. A winding mechanism is provided to support the nozzles that perform the above operations, and the winding end is held on the tip side of the spindle that is formed to project from the side of the winding machine main body, and tension is applied in the X-axis direction to cut and support the cutting end. After rotating downward about the X axis, the cutting line is opened and the line scissors and the discharging mechanism are provided for discharging downward.

【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings. 1 is a perspective view showing an embodiment according to the present invention, and FIG. 2 is a simplified side view thereof. This embodiment is applied to a four-axis spindle type winding machine. As shown in FIG. 3, the winding machine main body 1 having a built-in spindle drive mechanism for driving the four spindle shafts 9 by a servo motor or the like is made of metal casting, and the upper surface 1a is accurately cut or cut. Is ground. The accuracy of the tangling mechanism depends on the accuracy of the upper surface 1a, but normally, when processing one flat surface, it is relatively easier to achieve accuracy than when processing two surfaces.

In FIG. 1, a guide 2 provided on the upper surface of the winding machine main body 1, for example, an X-axis moving table 3 that is movable in the left-right direction along a linear slide bearing is attached, and on the upper surface of the X-axis moving table 3. A Y-axis moving base 5 that is movable in the front-rear direction is attached along the provided guide 4, and a Z-axis moving base 7 that can move vertically along a guide 6 provided on the front side surface of the Y-axis moving base 5. Is installed. Each of the moving bases 3, 5 and 7 is driven by a known servo motor to form a winding movement mechanism for the winding material nozzle.

The drive motor 15 of the X-axis moving table 3 is not mounted on the moving table 3 but is housed inside the main body 1 to reduce the weight of the entire moving table. The drive motor 18 of the Y-axis moving base 5 is mounted in the opposite direction to the Z-axis moving base 7 and in equilibrium with the weight of the Z-axis moving base 7 as a whole. The drive motor 21 of the Z-axis moving base 7 is provided at a position opposite to the side to which the nozzle 13 is attached, and the center of gravity of the Z-axis moving base 7 approaches the center of the X-axis moving base 3.

Four nozzles 13 are attached to the nozzle fixing bar 12 for guiding the wire material and winding the bobbin 14 and bending the terminals. The fixed bar 12 is supported from both sides by nozzle support mechanisms 24 and 24 'provided on the Z-axis moving table 7.

At the lower part of the front side surface of the winding machine main body 1 where the spindle shaft 9 is formed, a winding end processing mechanism 8 for performing end processing of the winding is provided. It is formed by the line picking mechanism and the line ejecting mechanism.

FIG. 4 is an enlarged perspective view showing an example of a winding terminal processing mechanism. The wire picking mechanism is composed of a fixed shaft 28 around which a wire is wound and held, and a rod-shaped claw 27 arranged so that the fixed shaft 28 can be pressed. A flat portion is formed at a contact portion between the claw 27 and the fixed shaft 28. The pawl 27 is opened and closed by being rotated about an axis by an air cylinder 30.

The wire discharging mechanism further smoothes the downward discharging of the wire when the pressing of the cutting line by the claw 27 is released after the rotary actuator 32 rotates the whole body downward and downward about the X axis. Therefore, the sleeve 29 is configured to slide from the fixed shaft 28 by the air cylinder 31. The line picking mechanism and the discharging mechanism are further movable in the X-axis direction as a whole.

Next, the operation of bobbin winding, terminal winding, and terminal processing will be described. First, as shown in FIGS. 5 and 6, the nozzle moving mechanism and the spindle by the moving tables 3, 5 and 7 are shown. After the winding drive to the bobbin 14 and the winding of the terminals are performed by the rotation driving mechanism of the winding end mechanism, the winding end is held by the wire pinching mechanism as shown in FIG. The axial movement applies tension to break the wire. Then, after the end of the cut line is held by the line picking mechanism, the rotary actuator 32 rotates downward about the X axis, and then the air cylinder 31 opens the pawl 27 as shown in FIG. The line end 26 cut off by cutting is released, and the downward movement of the sleeve 29 causes the line end 26 'to be discharged downward, whereby a series of windings, terminals are twisted, and the operation of the end treatment is completed. Become.

Since the flat portion of the fixed shaft 28 and the claw 27 is formed, when the wire is wound around the fixed shaft and the wire is cut by driving in the X-axis direction, the wire bites into the flat portion, and thus loosens. It stays within the specified X-axis movement amount without any measures. However, if such measures are not taken, the wound wire may become loose and exceed the specified X-axis movement amount, and as a result, it cannot be cut. Sometimes. Further, since the fixed shaft 28 is provided with the flat surface portion, the wire may bite into the flat surface portion and may not be opened. However, the movement of the sleeve 29 allows forcible discharge.

[0017]

[Effect of device]

 As described above, according to the present invention, the X-axis moving base that moves in one plane is formed on the upper surface of the base of the winding machine body, and the Y-axis moving base orthogonal to the one plane is formed on the upper surface of the X-axis moving base. The Z-axis moving base is formed on the upper surface of the Y-axis moving base, and the Z-axis moving base is provided with winding material nozzles. The drive source of the X-axis moving base is housed in the main body. The drive source of the axis moving table is provided on the side opposite to the Z axis moving table, and the drive source of the Z axis moving table is provided in the direction opposite to the nozzle mounting position, and the center of gravity of the Y axis moving table and the Z axis moving table is set to X. Since it is configured to approach on the axis moving table,

In a conventional winding machine in which an X-axis moving table and a Y-axis moving table that can move orthogonally on a plane are placed on the Z-axis moving table, the Z-axis moving table is mounted on the upper and lower sides of the winding machine body base. Due to the provision of rails for operation, the weight of the X-axis and Y-axis moving bases and the weight of the Z-axis moving bases can be moved up and down at the same time when the Z-axis moving bases for vertical movement are driven. Therefore, the movement of the movable table in the Z-axis direction, which needs to be moved up and down frequently, becomes slow. However, the present invention can eliminate such a drawback.

Further, according to the present invention, a wire picking mechanism including a fixed shaft for winding and holding a wire and a bar-shaped pawl arranged so as to hold down the fixed shaft, and a horizontal shaft It consists of a wire discharge mechanism in which the sleeve slides from the fixed shaft in order to discharge the wire downwards when the pressing of the cutting wire by the claw is released after the whole is rotated downward to the center. In the winding machine with the winding terminal processing mechanism, the contact portion between the claw and the fixed shaft is formed with a flat surface, and the claw is configured to rotate around the support shaft to be opened and closed.

Since the flat surface is formed on the fixed shaft and the claws, when the wire is wound around the fixed shaft and the wire is cut by driving in the X-axis direction, the wire bites into the flat portion, so that the wire does not loosen up to a predetermined value. It has the effect of staying within the range of the X-axis movement amount of. In a winding machine that does not take such measures, the wound wire may become loose and exceed the predetermined X-axis movement amount, and it may not be possible to cut. Also, since the fixed shaft is provided with a flat surface, the wire may bite into the flat surface and may not be released. However, the movement of the sleeve allows forcible discharge and accurate wire discharge. Therefore, it is possible to provide a winding machine that is easy to assemble, small, and inexpensive.
