Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic positioning device that can automatically position the center of a component at a predetermined position, and in particular is capable of automatic positioning regardless of the size of the component.

In general, automatic assembly equipment or automatic processing equipment that automatically attaches other parts to parts that are sent in sequence, or automatically performs predetermined processing on the parts, depends on the positioning accuracy of the parts that are sent. The precision of the finish is greatly affected.

However, since the conventional component positioning devices (jigs) installed in the above-mentioned automatic devices are designed to be fixed, they cannot follow variations in the finished dimensions of the components, and as a result, the same components cannot be placed. However, the positioning accuracy was not very satisfactory.

Furthermore, if the sizes of the supplied parts are completely different, it is necessary to replace the positioning jig each time with a positioning jig that corresponds to the size, which has the disadvantage of being very complicated. Moreover, since the automatic device must be stopped during the replacement, the advantages of the device are halved.

In view of these conventional drawbacks, the present invention provides an automatic positioning device that can automatically position the center of a rectangular component at a predetermined position regardless of its size. . The automatic positioning device according to the present invention will be explained in detail below based on the drawings. The figure shows a plan view of the device of the present invention, and numeral 1 shows a base main body for a component layer for attaching rectangular components 2 and 2', and positioning holes 3 and 3' for the main body are bored in both wings. There is.

Reference numerals 4 and 4' indicate a pair of fixed guide rollers installed upright on one end of the base body 1, and this loaf restricts the movement of the parts sent to the base body in one direction (upward in the drawing). are doing.

Further, this roller is rotatably attached to facilitate the movement of the component in the lateral direction (movement in the left and right directions in the drawings). ×1X in the center of the base body 1 for the said parts
A guide groove 5 having a predetermined width is formed in the ' direction, and a T-shaped slider part 6 is slidably attached to this guide groove as shown in the figure.
is configured to be able to slide in the direction away from the fixed guide loaves 4, 4'.

Further, the slider portion 6 is always urged toward the fixed guide rollers 4, 4' by springs 7, 7' whose one ends are fixed to the base body 1. Reference numerals 8 and 8' indicate L-shaped arm parts whose bases are rotatably attached to both ends of the head of the slider part 6 about shafts 9 and 9', respectively.

These arm parts 8, 8' extend approximately 99 degrees to the left and right with the base as the center.
It is expanded by 0 degrees, and rollers are attached to each end of the part so that it can smoothly move along the side wall of the part. 10 indicates a mobile village fixed to the slider section 6,
By moving the movable punch downward in the figure against the springs 7, 7', the distance between the fixed guide rollers 4, 4' and the L-shaped arms 8, 8' can be increased. has been done.

According to the above structure, when the part 2 is sent to the base body 1, each side wall of the part is moved by the biasing force of the springs 7, 7' to the fixed guide rollers 4, 4' and the pair of L-shaped arms. Part 8,
At this time, the component 2 is adjusted and moved in the left-right direction in the figure due to the balance of the forces at both ends of the two arm sections, and the center of the component is eventually positioned at X-X' of the base body 1. .

Therefore, even if the part to be loaded is part 2', which is significantly different in width and length from part 2, it will always be accurate and automatic due to the balanced relationship between the forces at both ends of both arms, as shown by the dashed line. It will be easy to understand that the position is

As described above, the automatic positioning device according to the present invention is a component in which a regulating member is erected on one end of the component so as to come into contact with one side wall of the component to restrict movement of the component in one direction. a base body for battle layer, a slider part attached to the base body so as to be able to slide in the direction of separation with respect to the regulation member, and a base part on the slider part at a position facing the regulation part village. The slider section or the pair of L-shaped arm sections are installed vertically in parallel to the upper surface of the base main body to freely rotate around the slider section or the upper surface of the base body. It is extremely useful for automatic assembly equipment and automatic processing equipment, as it enables accurate automatic positioning at all times even when the An advantageous automatic positioning device can be provided.

[Brief explanation of drawings]

The figure is a plan view of an automatic positioning device according to the present invention. 1 is the base body for parts counterfeiting, 2, 2r are parts, 4, 4'
5 is a fixed guide roller, 5 is a guide groove, 6 is a slider portion, 7 and 7' are springs, and 8 and 8' are arm portions.

Claims (1)

[Claims] 1. A component mounting base main body comprising a regulating member erected on one end thereof so as to come into contact with one side wall of the component to be mounted and restrict the movement of the component in one direction; a slider portion attached to the base body so as to be able to slide in the direction toward and away from the base body; and a pair of L-shaped arm sections that are erected so as to be able to freely rotate in parallel with each other, and each side wall of the component placed on the upper surface of the base main body is connected to the regulating member and the pair of L-shaped arm sections. An automatic positioning device characterized in that the core of the component can be automatically positioned at a predetermined position by clamping the component.
