[Conventional technology]

Conventionally, when mounting chip-shaped circuit components on a predetermined position on a circuit board, automatic This was done using a dynamic mounting device as follows. i.e. multiple containers The chip-shaped circuit components stored in bulk inside are piped to the distributor. Take out the guide tubes one by one and place them in the designated position on the template. They are each sent to a storage recess formed in and received there. This storage recess is for each It is arranged to match the position where the top-shaped circuit components are mounted on the circuit board. and, A chip-shaped component stored in the storage recess is removed by a component moving means having a suction unit. The circuit components are moved to the circuit board while retaining their relative positions when installed. It will be posted. As a result, each of the chip-shaped circuit components is placed at a predetermined position on the circuit board. will be installed. Adhesive is applied to the circuit board in advance at the locations where chip-shaped circuit components are to be mounted. Then, solder the mounted circuit components while temporarily fixing them with this adhesive. cormorant.

0003 In the template, a recess is formed to receive the chip-shaped circuit component. For this purpose, attach the guide case 61 on the baseboard 60 of the template 6, and A through hole 63 is provided at the bottom. Template 6 is the display of the multi-mounter device. When inserted directly under the tributor, there is a vacuum cage under template 6. A vacuum blower (not shown) is applied and connected through the exhaust duct 5. Due to this movement, the lower surface side of the template 6 is maintained at negative pressure. In this state, the disk Chip-shaped circuit component a falling through the guide tube 21 of the tributor 2 is received in the guide case 61. At this time, from the guide tube 21 to the guide case 6 Air is drawn to the back side of the template 6 through the through hole 63 formed at the bottom of the template 1. The chip-shaped circuit component a is sent to the guide case 61 by this air flow. After that, the template 6 moves to the suction head (suction head) and The chip-shaped circuit component a received in the guide case 61 is placed in the set slot of the suction head. It is adsorbed by the slider and mounted on the circuit board described above.

0004 The air vent hole 63 formed in the guide case 61 of the template 6 is , inspect whether the chip-shaped circuit component a is received in the guide case 61. It is also used as a light transmission hole. That is, the template 6 is On the way from directly under the tributor to under the suction head, as shown in Figure 3. The light source 15 is placed below the template 6, and the light receiver 9 is placed above it. Depending on whether or not the light from the light source 15 is received by the light receiver 9, the The presence or absence of the chip-shaped circuit component a is determined. Chip-shaped circuit components inside the guide case 61 If there is part a, the light passing through the through hole 63 is blocked by the part a, so the light receiver No light is received at 9. On the other hand, there is no chip-shaped circuit component a in the guide case 61. Since the light passing through the through hole 63 is blocked by the same component a, the light is not transmitted to the light receiver 9. Light is received.

[0005]

[Problem that the invention is trying to solve]

However, the guide case 61 detects the light transmitted through the through hole 63 as described above. The means for detecting missing items inside the guide case 61 may be obstructed by the surrounding wall of the guide case 61. Difficulty detecting light. Especially on the edge side of the template 6 where the angle of incidence on the photoreceiver 9 is large. In a certain guide case 61, the amount of light incident on the light receiver 9 is small, resulting in incorrect judgment during inspection. is likely to occur. In addition, it is difficult to distinguish between the through holes 63 of the adjacent guide case 61, and the holes are missing. When recovering items, visually search for the guide case 61 that is missing. is difficult.

[0006] Furthermore, for example, as in the guide case 61 on the left side of FIG. The chip-shaped circuit component a housed in should lie down in the ground 61. However, in reality, he stands up as shown by the solid line. Sometimes it happens. In this case, the bottom surface of the guide case 61 is formed biased towards the lower side. When the chip-shaped circuit component a is placed on the through-hole 63, the chip-shaped circuit component a is placed on the through-hole 63. Block 3. Therefore, in such a case, the chip-shaped circuit component a is stored in the guide case 61. Even if it is possible to check whether the posture is correct or not, It is not possible to detect whether or not the vehicle is stored in a prone position in the base 61. won.

[0007] If the through hole 63 is provided at the center of the bottom of the guide case 61, the chip-shaped circuit component a Not only is it stored in the guide case 61, but also whether it is stored in the guide case 61 or not. It is also possible to detect whether the device is stored in a collapsed state inside the device. but The through hole 63 is not only for inspecting missing items, but is also used as an air suction hole. Then, the chip-shaped circuit component a is received in the guide case 61, and the chip-shaped circuit component a is received in the guide case 61. For the purpose of knocking down the road part a with air flow, it is usually biased toward one end of the guide case 61. It will be established. Therefore, the purpose of this invention is to solve the problems of the conventional templates and to It is important to check not only whether the component is in place on the template, but also whether it is in place. We provide a template that can also check whether the product is stored in the correct posture. It is about providing.

[0008]

[Means to solve the problem]
