An overview of the entire mounting device for chip-shaped circuit components according to an embodiment of the present invention is shown in Figure 1. has been done. That is, a plurality of containers 1 containing chip-shaped circuit components in bulk are arranged. A delivery section 11, which is an escapement, is connected to this via a tube 10. has been done. Furthermore, a distributor 2 is arranged below this delivery section 11. ing.

[0008] This distributor 2 has a fixed frame fixed under the delivery section 11. The template 6 is arranged parallel to the template 23 under the template 23, and the template 6 is removably attached to the lower surface side. It has a movable frame 22 to which it is attached, and these fixed frames 23 and movable frames The beam 22 consists of four flexible columns of equal length whose four corners are connected to each other. connected. A vibrator 24 that vibrates the movable frame 22 is connected to the movable frame 22. , whereby the movable frame 22 is horizontally vibrated. Furthermore, a chip-shaped circuit component is proposed between the fixed frame 23 and the movable frame 22. Inside, flexible guide tubes 21, 21, . . . for conveyance are installed.

[0009] Below the movable frame 22 is a template placed on a template frame 65. 6 is inserted and fixed. This template 6 is a circuit of a chip-shaped circuit component. A guide case 61 is arranged on the baseboard 60 according to the mounting position on the board. It is. Then, this template 6 is inserted directly under distributor 2. When the lower end of the guide tube 21 connected to the movable frame 22 is located above each guide case 61 of the template 6.

0010 Also, at this time, the vacuum case 4 is placed under the template 6, and the The lower side of rate 6 is maintained at negative pressure. Template 6 also includes each guide case. A through hole (not shown) is provided at the bottom of the space 61. For this reason, the guide tube 21 from the back of the template 6 through the through hole opened at the bottom of the guide case 61. Air is drawn toward the surface, creating an air flow. Here, feed from the 1st side of each container. The chip-shaped circuit component a that has been dropped is dispersed due to its gravity and the air flow. It is fed through the guide tube 21 of the remodeler 2 and the guide case of the template 6. It is stored in the space 61.
