Detailed Description of the Invention [Field of Industrial Application] The present invention provides an automatic rubber damper mounting method and device for mounting a rubber damper for vibration absorption used in an optical disk player, etc. Regarding the suction head, it is particularly effective for attaching rubber dampers that are soft and easily deformed.

[Summary of the invention]

The present invention uses a suction head to suction the first flange of the rubber damper from above and inserts it into the mounting hole of the rubber damper mounting base, and then clamps the lower end of the rubber damper that has passed through the mounting hole with a chuck. By making the inside airtight and discharging the air inside the rubber damper, the diameter of the second flange part of the rubber damper is narrowed while pulling the chuck downward, and the second flange is passed through the mounting hole. The installation method includes a first air cylinder that is attached to the base via an arm and moves the entire installation unit up and down, and a second air cylinder that is attached to the bracket that is driven by the first air cylinder and moves the suction head up and down. A third air cylinder that moves the cylinder and chuck unit bracket up and down, a fourth air cylinder that is attached to the chuck unit bracket and drives the chuck unit back and forth, and a fourth air cylinder that is attached to the chuck unit and opens and closes the chuck. A rubber damper automatic mounting device consisting of a pair of fifth air cylinders and a chuck, and a truncated conical protrusion in the center of the lower surface of the cylindrical head to attract the first flange of the hollow rubber damper from above. This is a suction head that has an annular suction groove around the lower surface of the head and an exhaust hole inside the suction groove.

[Conventional technology]

In recent years, automation has progressed in the manufacturing of electronic devices, and most parts are now assembled or attached using automatic assembly equipment, and automatic assembly equipment for parts with complex shapes is being put into practical use. As technology advances, not only electronic parts but also parts with very complex shapes such as mechanical parts are being assembled or attached using automatic assembly equipment.

[Problem to be solved by the invention]

However, even if the mechanical parts that are automated by automatic assembly equipment have very complex shapes, when assembled or installed using automatic assembly equipment, metal or resin molded parts that are not easily deformed can be used. In most cases, it is extremely difficult to assemble or attach mechanical parts that are soft and easily deformed, such as rubber dampers for vibration absorption used in optical disc players, etc., to the chassis or base using automatic assembly equipment. It was difficult and we had to rely on manual labor.

The present invention solves the above problems and provides a method for assembling or attaching soft and easily deformable mechanical parts, such as rubber dampers for vibration absorption used in optical disc players, etc., using automatic assembly equipment. The object of the present invention is to provide a method for automatically mounting a rubber damper, an automatic mounting device, and a suction head used in the automatic mounting device.

[Means to try to solve the problem]

In order to solve the above problems, the present invention uses a suction head to suction the first flange of the rubber damper from above and inserts it into the mounting hole of the base for mounting the rubber damper, and then the lower end of the rubber damper is inserted into the mounting hole. By pinching the rubber damper with a chuck to make the inside airtight and exhausting the air inside the rubber damper, the diameter of the second flange part of the rubber damper is narrowed and the chuck is pulled downward, and the second flange is inserted into the mounting hole. A first air cylinder that is attached to the base via an arm and moves the entire installation unit up and down, and a suction head that is attached to a bracket that is driven by the first air cylinder. a second air cylinder that moves the chuck unit up and down; a third air cylinder that moves the chuck unit bracket up and down; a fourth air cylinder that is attached to the chuck unit bracket and drives the chuck unit back and forth; A rubber damper automatic mounting device consisting of a pair of fifth air cylinders that are attached and open and close the chuck, and a chuck, and a cylindrical head underside for suctioning the first flange of the hollow rubber damper from above. The suction head is equipped with a truncated conical protrusion in the center, an annular suction groove around the lower surface of the head, and an exhaust hole within the suction groove.

[Function] The present invention employs the automatic rubber damper mounting method, the automatic mounting device, and the rubber damper suction head, so that the rubber damper can be soft and soft, like the vibration-absorbing rubber damper used in optical disc players. Even mechanical parts that are easily deformed can now be assembled or installed using automatic assembly equipment.
