Abstract

PURPOSE:To allow a cassette to be smoothly replaced and an underside contour of the cassette top part to be freely designed by causing the cassette to be loaded and unloaded in a vertical direction relative to both a supply section and a replenish section with loading means and thus avoiding any loading in a sliding position. CONSTITUTION:A cassette 3 at a pickup position P is transferred to a point immediately below a first loading robot 7 by causing a transfer stand 5 of a supply section to move in an X-axis direction. Then, a chucking part 9 of the robot 7 lowers (in a Z-axis direction) to chuck the cassette. In a replacement station 6 a chucking position T of a predetermined cassette is determined at a point immediately below a second loading robot 8. Then, the chucking part 9 of the loading robot 7 moves from the supply section to the replacement station 6, while the chucking part 9 of the loading robot 8 moves from the replacement station 6 to the supply section (both in a Y-axis direction). During the time in which each chucking part 9 is lifted and moved in the Y-axis direction, a box 10 is moved by one pitch (p) in the X-axis direction on the replacement position 13.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a supply section that stocks cassettes of taped components supplied to a component mounting section, a supply section that stocks cassettes that are supplied to this supply section, and a supply section that stores cassettes of taped components supplied to a component mounting section. The present invention relates to a component mounting apparatus including a transfer means for transferring a cassette between the parts.

2. Description of the Related Art A conventional mounting device, as disclosed in, for example, Japanese Patent Laid-Open No. 62-83964, has a structure in which a cassette is slid and transferred between a supply section and a replenishment section using a transfer means. ing. The supply section and the replenishment section are each provided with a guide groove for guiding the slide of the cassette.

Problems to be Solved by the Invention However, in the conventional example described above, tape debris and dust tend to accumulate on the sliding surface of the guide groove, which hinders smooth cassette replacement and tends to result in inaccurate cassette positioning itself. There is a problem.

Furthermore, the tip of the cassette is equipped with an arc-shaped guide section that guides the used tape after the parts have been taken out, but since the entire bottom surface of the cassette is a sliding surface, the guide section cannot be extended to the bottom surface. There is also a problem in that the shape of the lower part of the cassette is restricted. For example, when increasing the diameter of a large-diameter X-Y table to correspond to the size of a board on which components are mounted, a slide-type cassette cannot have a guide section extending on its lower surface. It is impossible to avoid increasing the size of the mount head by inserting the Y table into the lower surface of the supply section.

In view of the above-mentioned problems, the present invention aims to provide a component mounting device that allows smooth exchange of cassettes and allows the shape of the lower surface of the tip of the cassette to be designed more freely than in the conventional example. purpose.

Means for Solving the Problems In order to achieve the above object, the present invention has a cassette that can be attached to and removed from the supply section and the replenishment section in the vertical direction, and the transfer means that allows the cassette to be attached to and removed from the supply section and the replenishment section. It is characterized in that it is held so that it can be moved up and down.

Effects According to the above configuration, the cassette can be attached to and detached from the supply section and the replenishment section in the vertical direction by the transfer means,
This allows you to avoid transferring slides between the two parties.
It is possible to eliminate all the problems caused by the conventional slide grooves, such as inaccurate positioning and problems with smooth replacement.

In addition, the cassette is attached to and removed from the supply section and the replenishment section in the vertical direction by the transfer means, and is transferred between the two by the transfer means, so the shape of the lower surface of the tip of the cassette can be changed more freely than in the conventional example. As a result, it is possible to avoid increasing the size of the mount head by, for example, allowing the X-Y table to sneak under the supply section.
