Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a component suction mechanism in which suction pads are attached to both sides of a suction head and the suction head is replaced when the shape of the suction component changes.

[0002]

[Prior Art]

 Next, the configuration of the component suction mechanism according to the conventional technique will be described with reference to FIG. In FIG. 3, 4 is a component such as IC, 5 is a suction head, and 6 is an adapter. A through hole 5A is formed in the suction head 5, a recess 5B having an outer diameter larger than that of the through hole 5A is formed in the through hole 5A, and a recess 5C having an outer diameter larger than that of the recess 5B is formed in the recess 5B. A suction pad 6B is attached to the attachment ring 6A of the adapter 6, an O-ring 6D is attached to the convex portion 6C of the attachment ring 6A, and a nozzle hole 6E is formed in the center of the adapter 6. The attachment ring 6A is held in the concave portion 5C of the suction head 5, and the O-ring 6D seals between the convex portion 6C and the concave portion 5B. In FIG. 3, when air is sucked from the through hole 5A, the suction pad 6B sucks the component 4.

[0003]

[Problems to be solved by the device]

 In FIG. 3, if the shape of the component 4 changes, the adapter 6 needs to be replaced. In order to replace the adapter 6, the mounting ring 6A, the suction pad 6B, and the O-ring 6D must be removed, and another adapter 6 of a different shape must be attached to the suction head 5, which requires time and effort. Further, when the O-ring 6D is inserted into or removed from the recess 5B of the suction head 5, the O-ring 6D may be damaged and the airtightness may be impaired. It is an object of the present invention to provide a component suction mechanism in which suction pads are attached to both sides of a suction head and the suction head is replaced when the suction component changes.

[0004]

[Means for Solving the Problems]

 In order to achieve this object, in the present invention, the suction block 1 in which the through hole 1A is opened and the through hole 2A are opened, and the recess 2B larger than the inner diameter of the through hole 2A is formed in the through hole 2A. The suction head 2 that is attached to the suction block 1 in such a manner as to communicate with the through hole 1A, and the suction surface of the suction pad 3A and the suction surface of the suction pad 3B are attached back to back to the connection ring 3C, and the connection ring 3C is suctioned. The head 2 is provided with an adapter 3 held in the recess 2B and provided with a nozzle hole 3D.

[0005]

[Action]

 Next, the structure of the component suction mechanism according to the present invention will be described with reference to FIG. In FIG. 1, 1 is a suction block, 2 is a suction head, and 3 is an adapter. A through hole 1A is formed in the suction block 1, a through hole 2A is formed in the suction head 2, and a recess 2B larger than the inner diameter of the through hole 2A is formed in the through hole 2A. The suction head 2 is attached to the suction block 1 so that the through hole 2A communicates with the through hole 1A.

The adapter 3 includes a suction pad 3A, a suction pad 3B, a connection ring 3C and a nozzle hole 3D, and the suction surface of the suction pad 3A and the suction surface of the suction pad 3B are mounted back to back on the connection ring 3C. To be The connection ring 3C is held in the hole 2B of the suction head 2, and a nozzle hole 3D is formed in the center of the adapter 3.

In FIG. 1, the suction head 2 is attached to the suction block 1, air is sucked from the through hole 1A, and the component 4 is sucked by the suction pad 3B. The suction pad 3A hermetically seals the connection between the suction head 2 and the suction block 1.

[0008]

【Example】

 In FIG. 1, the suction head 2 and the suction block 1 are attached with a catch clip 1B. Even if a gap is formed between the suction head 2 and the suction block 1, the suction pad 3A made of a soft material such as rubber covers the through hole 1A, so that suction air does not leak at the connection surface. According to the catch clip, the suction head 2 can be easily replaced.

Next, the perspective view of FIG. 1 will be described with reference to FIG. In FIG. 2, the suction block 1 to which the suction head 2 is attached is moved up and down by the cylinder 7. By sucking air from the suction head 2, the component 4 is sucked, and by stopping suction of air from the suction head 2, the component 4 is released from the suction head 2.

[0010]

[Effect of the device]

 According to this invention, the suction head having suction pads on both sides is attached to the suction block, the first suction pad hermetically seals the connection between the suction head and the suction block, and the second suction pad sucks components. The components can be sucked while maintaining airtightness, and if the component to be sucked changes, it can be replaced with a suction head suitable for the component.
