Description

[Detailed description of the invention] (Industrial application field) The present invention, when attaching electronic components such as ICs to a printed circuit board, etc., holds the electronic components and moves them to the top of the printed circuit board. The present invention relates to a component insertion device for aligning connection leads (legs) with holes in a printed circuit board, etc., and inserting the leads into the holes by pressing when they are aligned.

(Prior Art) The above-mentioned component insertion device generally places a printed circuit board or the like as a component insertion member horizontally, lowers the electronic component from above, and inserts the lead into the hole.
Along with the electronic component being sucked and held by the vacuum suction device, the weight of the component insertion device and the pressure of the spring used to insert the lead of the electronic component into the hole act as a force that presses the electronic component toward the printed circuit board. Become.

(Problem to be solved by the invention) In the case of a component insertion device, when the leads (legs) of the held component do not match the holes in the printed circuit board, etc., the component is moved over the surface of the printed circuit board, etc. This movement will help find the hole. Therefore, as mentioned above, if the weight of the component insertion device or the pressure of the spring is applied to the component lead, the tip of the lead will rub against the surface of the printed circuit board, potentially causing damage. . The present invention has been developed in view of this point, and is designed to reduce the weight of the component insertion device by the force of the spring.

(Means for Solving the Problems) As a means for solving the above problems, the present invention has a component inserting device that includes a holding mechanism that removably holds the parts to be inserted, and a holding mechanism that holds the parts to be inserted. A positioning correction mechanism that moves on a plane of the insertion member, a support body that supports the positioning correction mechanism, and a mounting body that attaches the whole of these to a robot etc. are provided, and the support body is movable relative to the mounting body. , an elastic body is interposed between the support body and the mounting body so that the holding mechanism acts in a direction away from the component insertion member.

(Function) With this configuration, the weight of the component insertion device is offset by the spring, so unlike the conventional device, it is possible to place electronic components on the component insertion member (printed circuit board) while gripping them. The component insertion member will not be damaged when moving for positioning.

(Example) Next, an example of the present invention will be described with reference to the drawings. 1 is a component insertion device, which basically has an electronic component (IC, etc.) as a component to be inserted.
2, a holding mechanism 3 that grips and holds it by suction, and a printed circuit board 4 that is a component insertion member.
The positioning correction mechanism 5 has a positioning correction mechanism 5 that is moved on a plane (see FIG. 2), a support body 6 that supports the positioning correction mechanism 5, and a mounting body 7 that attaches the whole of these to a robot or the like. 2a is a lead of the electronic component 2, 4a is a hole provided in the printed circuit board 4 for inserting the lead 2a, 7a is a flange for attaching the mounting body 7 to the arm of the robot, and 8 is a hole for positioning and correcting the holding mechanism 3. This is a shaft supported inside the mechanism 5.

This type of component insertion measure has already been put into practical use, and an application for utility model registration has been filed (for example, in the 1980s
-040998), to give a brief description here, the positioning mechanism 5 moves the shaft 8 in the X-Y direction using two actuators installed in intersecting directions in a horizontal plane, and moves the lead 2a of the electronic component 2. The hole 4a of the printed circuit board 4 is aligned with the hole 4a of the printed circuit board 4. The holding mechanism 3 is attached to a shaft 8 that is moved in the X-Y direction by a positioning mechanism 5. Although not shown, this holding mechanism 3 has a hole for suction on its lower surface, and the electronic component 2 is suctioned by applying negative pressure from a separately provided vacuum pump to this hole.

The support body 6 that supports the positioning mechanism 5 is a mounting body 7
It is inserted into the inside of , and is supported by a bearing 9 so as to be vertically movable. Thereby, the support body 6 is supported so as to be movable relative to the mounting body 7. A stopper 10 made of a plate material having a diameter larger than that of the bearing 9 is attached to the upper end of the support body 6 with a bolt 11. A spring 12 as an elastic body is interposed between the portion 7b and the portion 7b. This spring 12 applies a force to the holding mechanism 3 in the direction away from the printed circuit board 4 .

Explain the operation. A robot or the like (not shown) moves the component insertion device 1 to the upper part of the storage area for the electronic components 2, and applies negative pressure to the holding mechanism 3.
to hold the electronic component 2 by suction. Next, the arm of the robot is operated to move the electronic component 2 above the printed circuit board 4 to which it is to be attached. In this state, if positive air pressure is applied inside the holding mechanism 3 and the lead 2a of the electronic component 2 is inserted into the hole 4a of the printed circuit board 4, the work is completed.
may not be aligned at once (see Figure 2), so the positioning mechanism 5 moves the electronic component 2 to
Move in the Y direction and search for a matching location. At this time, since the spring 12 lifts the portion below the support 6 upward, the contact force between the lead 2a and the top surface of the printed circuit board 4 is also reduced, and position correction can be performed with a small force. The leads 2a do not damage the top surface of the printed circuit board 4.

(Effect of the invention) As explained above, the present invention has an elastic body interposed between the supporting body and the mounting body, which are movable relative to each other, so that the holding mechanism acts in the direction away from the component insertion member. , when performing positioning work,
The lead of the electronic component is not caught on the component insertion member (printed circuit board, etc.), and the insertion rate can be improved.
