Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electronic component supply and positioning device, which is used to clamp uneven components at the same time as properly positioning them in electronic component insertion work that requires high precision. It will be done.

Structure and problems of conventional examples When inserting electronic components, for example, DIP type ICs are molded as shown in FIG. As shown, some parts differ from the parts shown in FIG. 5 in dimensions a and a' from the end surface of the part body to the part terminal 22.

As shown in FIG. 7, the conventional component positioning device uses a stopper 19 and a plate 20 to control the end surface of the component body for positioning. However, parts with burrs 18 appearing on the end face of the part body as described above (Fig. 5), or parts with variations in dimensions a and a' from the end face of the part body to the component terminal (Figs. 5 and 5) When attempting to clamp the component (parts shown in Figure 6) by regulating their positions with the end faces of the component body, the dimensions from the end face of the component body to the component terminals are not constant, so the chuck claws are closed as shown in Figure 8 The position of the groove 21 and the terminal 22 of the component differs by δ ₁ or δ ₂ , which poses a problem in that the component terminal cannot be accurately held.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems, and uses a simple mechanism to accurately position component terminals, and also enables checking of terminals at the extreme ends of components.

Structure of the Invention The present invention includes a guide block that supports a component body and regulates opposing component terminals, and a pin and a compression spring provided through the guide block so as to be slidable in the vertical direction. , and a stopper that contacts the component terminal to regulate its position; a plate that moves from the opposite direction of the stopper and the component and regulates the other end of the terminal or the component body; and a plate provided above the stopper that can be raised and lowered. The chuck pawl is arranged so that it can push down the stopper by descending and chuck the end of the component terminal. With this configuration, positioning can be performed using the component terminals, and components with different numbers of terminals can be handled by replacing the guide block.

DESCRIPTION OF THE EMBODIMENTS The following describes an embodiment of the apparatus of the present invention with reference to the drawings. 1 is a carrier holder, 2 is a carrier that stores parts, 3 is a chute part, 4 is a shutter for parts, 5 is a guide block that supports the parts body, and a pin 7 with a compression spring 6 wound around it is installed at the tip. has been done. Reference numeral 8 denotes a positioning stopper that penetrates through the pin 7, and is formed in a U-shape in plan, and restricts the rotational direction by sandwiching the guide block 5 (FIG. 3). Reference numeral 9 denotes a plate screwed to the component supply section, which contacts the side surface of the component main body on the guide block 5. 10 is a chuck claw. Guide block 5, pin 7, positioning stopper 8, roller 11
A parts supply section consisting of a cylinder 12 is movable by a cylinder 12. Reference numeral 13 denotes a cam floor surface on which the roller 11 moves when the supply section is drawn by the cylinder 12. 14 is a fulcrum pin of a lever 15 for opening and closing the shutter 4. Note that 16 is a bolt that fixes the guide block 5 to the parts supply section.

Next, the operation will be explained.

The parts stored in the carrier 2 naturally fall through the chute section 3 and reach the shutter 4. Next, when the cylinder 12 pulls the parts supply section, the roller 11
moves along the cam floor surface 13, and the guide block 5 is in the state shown by the two-dot chain line. In this state, the lever 15 is pushed up by the roller 11 using the pin 14 as a fulcrum, and the shutter 4 is pushed up, the part is transferred to the guide block 5, and by operating the cylinder 12 again, the plate 9 comes into contact with the side surface of the part body. and a stopper 8 in contact with the component terminal,
Return to original position. When the chuck claw descends and the stopper 8 is moved downward against the compression spring 6 against the component whose position is regulated by the main body and the component terminal, the fourth
As shown in the figure, terminals at the ends of the parts can also be clamped. After the component is clamped, when the chuck claw is raised, the stopper 8 is also returned to its original position as shown in FIG. 2 by the force of the spring.

In the device with the above configuration, by providing a stopper for positioning using the component terminal, appropriate positioning can be achieved even when there is a burr on the end surface of the component body or when the dimension from the end surface of the component body to the component terminal is different. It is also possible to hold component terminals. Furthermore, since the guide block 5 is detachable using the bolt 16, it can be easily replaced.

Effects of the Invention Since the present invention has the above-described configuration, even if there is a burr on the end surface of the component body or the dimension from the end surface of the component body to the component terminal is different, the component terminal can be used properly. The position can be regulated and the ends of component terminals can also be held. Furthermore, since the dedicated guide block is removable, it can be replaced to accommodate parts with different numbers of terminals, which has great effects.
