Description

Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to an electrical component positioning/insertion method for positioning and inserting an electrical component such as a connector having two rows of upper and lower leads with spring properties into an end of a printed circuit board. Regarding the mounting device.

[Background of the invention]

FIG. 5 is a schematic perspective view showing a conventional device for positioning and inserting a connector onto a printed circuit board, and FIG. 6 is an enlarged cross-sectional view of a portion thereof.

In FIG. 5, reference numeral 52 denotes a moving table on which a printed circuit board 53 is set, and is movable in the X direction along a guide shaft 60. 5
5 is a magazine in which the connector is stored. As shown in FIG. 6, a slider 59 and a guide member 61 are provided at the lower end of the magazine. 56 is a motor for moving the slider 59 forward and backward in the Y direction; 57 is a guide member 61;
This is a pneumatic cylinder for moving the .

Explain the action. After moving the moving table 52 and positioning the printer board 53 at a predetermined position, the motor 56 is activated to move the slider 59 forward. The connector 62 at the bottom of the magazine 55 rests on the component receiving surface 59b of the slider 59;
It is pushed out together with the slider 59 while being engaged with the slider 9a. As the connector 62 moves forward, the leads 63 in the two upper and lower rows of the connector 62 are guided by the inclined surface of the guide member 61 and are gradually expanded vertically. The leading part of the lead 63 is the printed circuit board 53
When the guide member 61 moves forward beyond the edge of the lead 63, the motor 56 is stopped and the pneumatic cylinder 57 is operated at the same time to move the guide member 61 to a position where it does not engage with the lead 63. After that, the motor 56 is operated again,
The connector 62 is further advanced. When the printed circuit board 53 enters between the leads 63 to a predetermined depth, the motor 56 is operated in the opposite direction, and the slider 5
Move 9 back. This completes the positioning and insertion of the connector 62.

Now, when connecting a printed circuit board to a motherboard, attach a pin connector to one side and a socket connector to the other. When a plurality of such connectors are arranged side by side and attached to a board, it is necessary to strictly control the positional accuracy between the connectors in order to satisfy the fitability of the connectors.

In the conventional device described above, when the guide member 61 is retracted from the lead position, the connector 62 moves due to friction between the guide member 61 and the lead 63, and positional deviation is likely to occur. However, the configuration is such that the connectors are positioned and attached one by one. Therefore, when attempting to attach a plurality of connectors side by side, there is a problem in that errors in the attachment positions of the connectors accumulate and the positioning accuracy between the connectors decreases. This problem is becoming more and more serious as connectors and the like become smaller and the mounting density of printed circuit boards increases.

[Purpose of the invention]

An object of the present invention is to solve the above-mentioned conventional drawbacks and to provide an electrical component positioning inserter that can simultaneously position and insert a plurality of electrical components having two rows of springy leads onto a printed circuit board with high mutual positional accuracy. The purpose of this invention is to provide a mounting device.

[Summary of the invention]

The present invention accommodates and fixes electrical components such as connectors in a plurality of recesses arranged in an electrical component holding member in order to maintain mutual positional accuracy of the electrical components. The device is characterized by providing means for holding it in an expanded state.
