Therefore, the transformer iron core automatic laminating apparatus is not a method of fitting the step wrap 10 to the conventional long fixed alignment pin 420, but a pair of alignment pins 420 for the step wrap 10 to be fitted and fixed. By adjusting the height of the), it is possible to prevent the damage of the step wrap 10 due to the alignment pin 420 when the transfer stacking of the step wrap 10 through the robot arm 300 Have

In addition, the transformer core core automatic stacking device operates the same operation according to the height adjustment of the pair of alignment pins 420, to facilitate the fitting of the step wrap 10 to the alignment pins 420. Can be.

3 is an operational state diagram of the alignment pins for the elliptical rotating member and the spring-type expandable alignment pin unit and the iron core automatic laminating apparatus including the same according to the present invention.

As shown in FIG. 3, the alignment pin 420 has a smaller diameter than the alignment hole (not shown), and is formed to be expandable to the size of the alignment hole (not shown).

First, an elliptical center axis 420a is formed in the alignment pin 420.

In addition, the alignment pin 420 is provided with an expansion member 420b on the outer wall of the alignment pin 420 so as to abut on both sides of the portion having a short horizontal distance of the central axis 420a.

Here, each of the expansion members 420b is connected through a spring 420d.

On the other hand, the alignment pin 420 is provided with a rotating member 420c below the central axis 420a of the oval.

The rotating member 420c rotates the central axis 420a by 90 degrees so that both side surfaces of the portion having the long horizontal distance of the central axis 420a come into contact with the expansion member 420b. ).

That is, the alignment pin 420 is formed to have a diameter smaller than that of the alignment hole (not shown) formed in the iron core before the stacking of the step wraps 10, and the stacking member 210 after the stacking of the step wraps 10 is stacked. Drive the rotating member 420c to rotate the central axis 420a of the ellipse, thereby expanding the expansion member 420b so that the alignment pin 420 corresponds to the alignment hole (not shown). It can be made to have a diameter.

In more detail, the alignment pin 420 drives the rotating member 420c to align the elliptical center axis 420a to align the alignment hole (not shown) through the expansion of the expansion member 420b. Both side surfaces of the portion having a long horizontal distance may be rotated to contact the expansion member 420b to expand the alignment pin 420.

At this time, since the alignment pins 420 are connected between the expansion members 420b through the spring 420d, expansion and contraction of the expansion member 420b is not only easy, but also the expansion member ( When the expansion and contraction of 420b) can be securely fixed accordingly.

Therefore, an elliptical rotating member and a spring-based expandable alignment pin unit and an iron core automatic laminating apparatus including the same may expand the alignment pin 420 to correspond to an alignment hole (not shown) formed in the iron core when iron cores are stacked. Therefore, it has the effect which can make alignment of the laminated iron core easy.

4 is an embodiment of an automatic elevating device including an elliptical rotating member and an expandable alignment pin unit by a spring, and the same according to the present invention.

In addition, the alignment pin 420 includes three expansion members 420b so as to correspond to the number of corners of the central axis 420a of the triangle.

The expansion member 420b is formed such that an outer wall of the alignment pin 420 is expandable through rotation of the central axis 420a of the triangle.

That is, before the alignment pin 420 is extended, the corner portion of the central axis 420a of the upper angle is positioned between the expansion members 420b, and when the alignment pin 420 is extended, the center of the triangle is extended. By rotating the shaft 420a about 60 degrees through the rotating member 420c to be described later, an outer wall of the alignment pin 420 is positioned so that the corner portion of the triangular central axis 420a is positioned as the expansion member 420b. Can be extended.

In more detail, the alignment pins 420 are formed to have a diameter smaller than that of the alignment holes (not shown) formed in the iron core before the stacking of the step wraps 10. By rotating the central axis 420a of the triangle through the rotating member 420c, the alignment pin 420 may be extended to have a size corresponding to the alignment hole (not shown).

Meanwhile, the alignment pin 420 has three expansion members 420b connected to each other through the spring 420d, so that the expansion pin 420b is securely fixed when the expansion member 420b extends and contracts through the rotation member 420c. This can be done.

Accordingly, the elliptical rotating member and the spring-type expansion alignment pin unit and the iron core automatic laminating apparatus including the same rotate the central axis 420a of the triangle to correspond to the alignment hole (not shown) formed in the iron core when the iron core is stacked. Since the alignment pin 420 may be expanded, the alignment pin 420 may be expanded and contracted by driving the rotating member 420c.

5, 6, 7, 8, and 9, the operation of the step wrap stacker 100 of the elliptical rotating member and the spring-type expandable alignment pin unit and the iron core automatic laminating apparatus including the same as follows. same.

First, the step wrap stacker 100 includes a unit iron core pedestal 110, a step wrap pedestal 120, and a unit iron core moving arm 130.

The unit iron core supplied from the outside is stored in the upper portion of the unit iron core pedestal 100.

At this time, the unit iron core may be transferred by the operation of the unit iron core moving arm 130 provided at one side of the step wrap stacker 100.

The unit iron core moving arm 130 is hinged to an upper portion of the support base 130a and the support 130a provided at one side of the step wrap stacker 100, and has an angle of about 90 degrees from the upper portion of the unit iron core pedestal 110. It is provided with a hinge coupling member (130b) coupled to the rotatable and the suction plate (130c) is coupled to one end of the hinge coupling member (130b) to suck the unit iron core.

Here, the unit iron core pedestal 100 moves the hinge coupling member 130b to the upper portion of the unit iron core through a control unit (not shown) provided separately from the outside.

Next, the magnetic force flows to the suction plate 130c provided at one end of the hinge coupling member 130b to adsorb the step wrap 10.

Subsequently, the position of the hinge coupling member 130b is moved to be perpendicular to the unit iron core pedestal 110 in a state where the step wrap 10 is adsorbed on the suction plate 130c.

In order to transfer the step wrap 10 to the step wrap pedestal 120, a controller (not shown) controls the hinge coupling member 130b to be positioned as the step wrap pedestal 120 along the support 130a.

Thereafter, the hinge coupling member 130b is moved at a right angle with respect to the support 130a, and the step wrap 10 is fitted to the fixing pin 120a of the step wrap pedestal 120.

Here, the step wrap pedestal 120 may be manufactured to be inclined at a predetermined angle so that the position of the reference hole (not shown) of the step wrap 10 can be easily aligned.
