Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a suction device, and more particularly, to a suction device using a multi-motor fan arranged in an industrial robot hand or the like.

[0002]

[Prior art]

 The following devices are known as conventional devices for moving a wiring board having such a wiring pattern. The wiring board is moved while being sandwiched by a plurality of claw-shaped objects and placed at a target position.

The power of the electromagnetic coil is turned on, and the wiring board is moved while attracting the wiring board with the electromagnetic force, and the power of the electromagnetic coil is turned off to release the electromagnetic force and the object is placed at the target position. The wiring board is moved while floating and adsorbed by the suction force generated by the air suction generated by the rotation of the motor fan, etc., and the rotation of the motor fan is weakened or stopped by approaching the target position to reduce the suction force. Detach the wiring board and place it at the target position.

The wiring board is placed on a conveyor such as a belt conveyor and transported, and the wiring board is lowered to a target position.

[0005]

[Problems to be solved by the device]

 In the above-mentioned conventional device for moving a wiring board having a wiring pattern, in the case of a device for sandwiching with a claw-shaped object, the wiring board is scratched when the wiring board is sandwiched with the claw-shaped object. There is a risk of damage, and there is a high risk of dropping the wiring board while it is being pinched and moved, which poses a safety problem. In the case of a device utilizing electromagnetic force, a non-magnetic wiring board such as a copper plate cannot be adsorbed and cannot be used.

Further, in the case of a device utilizing the air suction force, it is difficult to suck when the wiring board is perforated with a chemical or the like by an etching method because it is difficult to suck the wiring board. Furthermore, in the case of a device that uses a conveyor, the end of the wiring board may come into contact with the side of the conveyor, etc., causing bending or damage when loading or unloading the conveyor. Is not suitable.

Therefore, there arises a technical problem to be solved in order to safely and promptly move a precision member such as a non-magnetic thin copper plate having a wiring pattern to a target position. The invention aims to solve the problem.

[0008]

[Means for Solving the Problems]

 The present invention has been proposed to achieve the above-mentioned object, and is a suction device for moving a wiring board that is provided with a wiring pattern and has a mesh shape, and is attached to the lower part of the box. And a motor fan is disposed on the upper surface of the box, the motor fan is driven to generate a vacuum state in the box, and a cover is provided above the exhaust port of the motor fan. A suction device using a multiple motor fan configured so that the exhaust port of the motor fan can be shielded by lowering the cover by an actuator such as an air cylinder.

[0009]

[Action]

 The motor fan provided in the upper part of the box of the suction device is rotated to generate a vacuum state in the box, and the outside air is introduced into the adsorption part provided in the lower part of the box from below. The robot hand is moved while sucking the wiring board provided with the wiring pattern together with the outside air to the suction portion to bring the wiring board closer to the target position from above.

When the arm of an actuator such as an air cylinder is extended to the exhaust port of the motor fan to bring the cover into close contact and the exhaust port is shielded, the evacuation state inside the box is stopped and the wiring board is sucked. It is detached from the section and placed at the target position. Further, when the cover is moved away from the exhaust port of the motor fan, a vacuum drawing state is generated again in the box, and the metal plate can be sucked and transported by the suction portion.

【Example】

 An embodiment of the present invention will be described below in detail with reference to FIGS. FIG. 1 shows a suction device 1 and reference numeral 2 is a box. The box 2 has an open bottom surface and an intake hole 2a, 2a ... Opened on the top surface. On the upper surface of the box 2, motor fans 3, 3 ... An adsorption part 4 is disposed below the box 2, and the adsorption part 4 is joined to the box 2 by covering a mesh-shaped metal mesh plate 5 with a cloth 6 having good air permeability on the lower surface and the side surface.

A plate 8 is provided above the box 2 via guide posts 7, 7 ... And air cylinders 9, 9 are arranged on the upper surface of the plate 8. The arms 10, 10 of the air cylinders 9, 9 are loosely inserted into the holes 8a, 8a of the plate 8 and screwed to the cover 11. The cover 11 is composed of two horizontal plates, and an elastic rubber plate 13 is attached to the upper metal plate 12 from the lower part. The cover 11 is formed so as to be vertically movable by expanding and contracting the arms 10, 10 of the air cylinders 9, 9. Further, the suction device 1 is arranged in a robot hand (not shown) and can be moved.

When the suction device 1 is used, the motor fans 3, 3 ... Arranged on the upper part of the box 2 are driven to discharge air from the upper exhaust ports of the motor fans 3, 3. The inside of the box 2 is evacuated. As a result, the air in the vicinity of the lower part of the box 2 is sucked and then sucked from the suction part 4 formed of the cloth 6 and the metal mesh plate 5 provided in the lower part of the box 2.

The suction device 1 is moved to the upper part of the wiring board 14 placed on the upper surface of the work table 15 or the like by the operation of the attached robot hand, and further the robot hand is operated to operate the suction device 1 Are closer to the wiring board 14 from above. The wiring board 14 is sucked together with air by the suction device 1 and brought into close contact with the cloth 6 of the suction part 4. The robot hand is moved to the transportation destination while suctioning the wiring board 14 to the suction portion 4, and the wiring board 14 is brought close to the target position from above.

As shown in FIG. 2, the arms 10, 10 of the air cylinders 9, 9 are extended to lower the cover 11, and the rubber plate 13 of the cover 11 is pulled from above the motor fans 3, 3. Closes the air exhaust from the motor fans 3, 3 ... by making them in close contact with the exhaust port. Thus, the vacuuming state of the box 2 by the motor fans 3, 3 ... Is stopped, and the wiring board 14 adsorbed on the cloth 6 of the adsorbing part 4 loses its adsorbing force and is released from the adsorbing part 4. Separated and placed in the target position.

The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified version.

[0017]

[Effect of device]

 In this invention, as described in detail in the above-mentioned one embodiment, the suction device of the present invention generates a vacuum state by driving a motor fan, and the suction force of the suction unit covers the wiring board with cloth. Since it moves while sucking, it does not damage or bend the wiring board to be moved.

Further, since the motor fan is arranged on the upper surface of the box of the suction device without any gap, and the vacuum is generated in the box, the suction force in the suction part is strengthened, and the large area opening part is opened. The wiring board that it has can be sucked and moved. Further, since the suction device shields and opens the exhaust port of the motor fan using the cover, the suction force can be controlled without stopping the rotation of the motor fan.

Thus, since the process of sucking, moving and arranging the wiring board can be performed without stopping the rotation of the motor fan, it is possible to perform various kinds of processes such as quick and reliable transition between the respective processes. This is a device that has a practical effect.
