3 is a contact portion with a component provided on the gripping element.

After placing the component on the first reference surface, the slider 38 is driven and the contact portion 43 of the gripping element 41 is pressed against the second reference surface 37 to position it, and the slider 38 is further advanced, so that the gripping element 41 becomes the fulcrum. It rotates about a pin 40 as a center of rotation, and grips a component by a gripping portion 42 of a gripping element 41.

Problems to be Solved by the Invention In the conventional method, there are certain restrictions on the contact surface between the base, the single surface, and the component gripping element due to the regulation direction, and it is difficult to provide a non-contact surface. and the present invention is
A non-contact surface is provided for position regulation 2 and gripping of parts.

In addition, in the wire processing where both ends of the wire are twisted after winding, the component gripper is rotated 90 degrees to match the drawing direction of the wire with the center axis of the component, thereby realizing automation of wire twisting with a simple structure. This is what I did.

Means for Solving the Problems In order to solve the above problems, the component gripping tool was constructed as follows. The component gripping tool is composed of a component gripping part that regulates and grips the component, and a rotation drive part that rotates the gripping part by 90 degrees, and the component gripping part further includes a component regulating part that adjusts the position of the component, and a component holding part that adjusts the position of the component. It consists of a component fixing part that is pressed against and gripped by a surface. The component regulating section has two orthogonal reference planes (hereinafter, the horizontal reference plane will be referred to as the first reference plane and the vertical reference plane will be referred to as the second reference plane), and also has a built-in vacuum suction path. By providing a vacuum suction port on the reference surface, the parts can be attracted to the first reference surface and the position can be adjusted, and the structure can be adjusted without the mechanical parts coming into contact with the non-contactable surfaces of the parts. did. Further, the component fixing section includes a movable block that is movable in a direction approaching the component, and a clamper that rotates around a fulcrum provided on the movable block and grips the component.

For production Hereinafter, the operation of the present invention will be explained in accordance with the order of the winding process.

The component is supplied to the second reference surface while performing vacuum suction in the component regulating section. The parts supplied to the second reference surface are pressed against the first reference surface by vacuum suction and their positions are regulated. Next, the movable block of the component fixing part moves, and after the contact part of the clamper contacts the component fixing part main body, it rotates and presses the component against the second reference surface, adjusting the position of the component and gripping the component. Let's do it. Next, after winding the wire while passing it through the wire from the vertical direction, pull out both ends of the wire in the vertical direction, and twist the two wires in a straight line perpendicular to the straight line passing through the wire passing hole of the component. To enable seaming, the component gripping section is rotated by 90 degrees by the rotation drive means.
