Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component adsorber that can be used in an automatic mounting machine or the like for automatically bonding a component to a printed circuit board.

2. Description of the Related Art Conventionally, in an automatic mounting machine in which components are sucked, conveyed to a printed circuit board, and automatically inserted and mounted, as shown in FIG. Was not provided.

However, in the adsorber 11 as shown in FIG.
Even if an attempt is made to correct the suction position of the component 9 with the lever 10 that opens and closes only with the air hole 12, if the suction force is strong, it cannot be corrected correctly. If the suction force is weakened, the correction is performed correctly, but there is a problem that the component cannot be mounted correctly because the component is dropped or the suction position is shifted by a slight vibration.

SUMMARY OF THE INVENTION The present invention is intended to solve such a conventional problem, and it is possible to correct a suction position of a component with a weak force after the component is sucked, to suck a component with a strong force during moving mounting, and to perform accurate mounting. It is an object of the present invention to provide an adsorption method and an adsorbent that can be used.

Means for Solving the Problems In a component suction method and a component suction element of the present invention, a suction port for suctioning a component and a ball, roller or bearing for improving the movement of the component are used, and air for pushing down the ball, roller or bearing is used. There is an air hole to pass through.

According to the component suction method and the component suction element of the present invention as described above, the contact area between the component and the suction element can be reduced by pushing down the ball, roller or bearing after the component is suctioned, so that the suction position of the component can be reduced. Can be corrected with a weak force,
At the time of moving mounting, by removing air for pushing down a ball, a roller, or a bearing, the component and the adsorber are brought into close contact with each other, and the component is suctioned with a strong force, so that accurate mounting can be performed.

Therefore, according to the present invention, it is possible to quickly and accurately suction various large and small parts and hold the parts in a normal form,
Accurate implementation can be performed.

Embodiment Hereinafter, a component suction method and a component suction element according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front sectional view of a component sucker according to an embodiment of the present invention, FIG. 2 is a front sectional view of a state in which the sucker is lowered to suck a component, and FIG. It is a partial sectional view at the time of correcting a position of a part.

1 to 3, reference numeral 1 denotes a vertical drive cylinder, 2 denotes an adsorber, 3 denotes a guide which supports the adsorber 2 so as to be vertically movable, 4 denotes a joint, 5 and 6 denote air holes, Is ball 8
8 is a ball mounted on the tip of the air hole 5, 9 is a component, 10 is an opening / closing lever for positioning the component 9, 13 is a cylinder for opening and closing the lever 10, 14
Is a fulcrum pin of the lever 10.

In the above configuration, as shown in FIG.
As a result, the adsorber 2 descends downward, comes into contact with the component 9, removes air from the air hole 6, adsorbs the component 9, and raises the adsorber 2 by the cylinder 1. Next, compressed air is sent from the air hole 5 to push the ball 8 downward, as shown in FIG. In the state shown in FIG.
To rotate the lever 10 about the fulcrum pin 14
To perform positioning. At this time, when the air supplied to the air hole 5 is stopped, the component 9 is strongly held by the adsorber 2. Even if the lever 10 is opened by the cylinder 13 and the adsorber 11 is rotated, moved, or moved up and down in this state, the component does not drop or shift. The force at the time of position correction can be changed by changing the air pressure.

As described above, according to this configuration, the component is strongly held by the air hole 6 when the component is sucked, moved, and rotated, and when the position of the component is corrected, the ball 8 is in contact with the component, and the component can be corrected with a weak force. it can.

In addition, besides balls, even if rollers and bearings are used,
Similar functions and effects can be obtained.

Effects of the Invention As described above, according to the component suction method and the component suction element of the present invention, the component is strongly held when the component is suctioned, moved, and rotated, and the position of the component is corrected with a weak force. This makes it possible to hold the component in a normal form and to perform accurate mounting without damaging the component when supplying the component, which is very effective in improving workability.
