Suction device

The invention relates to a absorbing device, in particular to a T-shaped chute in which a plurality of sliding bodies are embedded in a plate body, and the exposed segment of the T-shaped chute is covered by the flexible piece floating cover, thereby adjusting The designer of the suction cup position at the bottom edge of the slider.

According to the first figure, the conventional plate absorbing device fixes a plurality of suction cups (10) to a positioning plate (20), and a suction branch pipe (31) is connected to each suction cup (10). Then, each of the suction branch pipes (31) is partitioned (the inner and outer zones are shown) to different pumping mains (30a, 30b); thus, the conventional plate absorbing device is attracted by the suction cup (10) ) can't move, so it can only suck the plates of different sizes by pumping in the zone or the whole zone, and can't adjust the position of the sucker (10) relative to the change of the size of the plate, so it can't get better sucking effect. Furthermore, since it is necessary to connect the suction branch pipe (31) to each suction cup (10), and then connect each suction branch pipe (31) to a different pumping main pipe (30a, 30b), the exhaust pipe is caused. The road looks complicated and messy.

The main object of the present invention is to solve the problem that the position of the suction cup of the prior art cannot be moved, and the position of the suction cup can be adjusted.

Another object of the present invention is to have a simple effect of the suction line.

In order to achieve the above effects, the structural features of the present invention include: a plate body having at least one T-shaped chute that is not penetrated, and a cover is disposed at the open end of the T-shaped chute, and the cover is a cover is connected to the exhaust pipe for pumping the T-shaped chute; a plurality of sliding bodies are formed with a T-shaped slide portion with respect to the T-shaped chute of the plate body, and the T-shaped slide rail portion is formed with a vent hole axially, and A suction cup positioning portion is formed below the T-shaped rail portion, the suction cup positioning portion is axially formed with a through groove, and the suction cup is positioned at a bottom edge of the suction cup positioning portion, and an air suction is formed between the ventilation hole and the suction cup. a channel; and a flexible piece that passes through the slot of each of the sliding bodies and has two ends fixed to the bottom edge of the plate body, and the floating cover covers the T-shaped sliding that is not covered by the positioning portion of the suction cup The slot is exposed.

In addition, the two open ends of the through groove are close to the top edge of the suction cup positioning portion, and further, an airtight ring is disposed on the top edge of the suction cup positioning portion. Further, the flexible sheet is a thin plate-shaped flexible sheet. Further, a fixing screw is further provided to the plate body at the chuck positioning portion.

First, referring to the second to fourth figures, the present invention includes: a plate body (40) having at least one un-through T-shaped chute (41) formed in the T-shaped chute (41) The open end is provided with a cover (42), and the cover (42) is connected to the exhaust pipe (43) for pumping the T-shaped chute (41); a plurality of sliding bodies (50) are opposite to the plate body The T-shaped chute (41) of (40) is formed with a T-shaped slide rail portion (51), and the T-shaped slide rail portion (51) is axially formed with a vent hole (52), and the T-shaped slide rail portion ( 51) a suction cup positioning portion (53) is formed below, the suction cup positioning portion (53) is axially formed with a through groove (54), and the suction cup (60) is positioned at a bottom edge of the suction cup positioning portion (53), and An air suction passage (55) is formed between the vent hole (52) and the suction cup (60); and a flexible piece (70) is passed through the through groove (54) of each sliding body (50), and The two ends are fixed to the bottom edge of the plate body (40), and the floating cover covers the exposed portion of the T-shaped chute (41) not covered by the suction cup positioning portion (53).

In addition, the two open ends of the through slot (54) are adjacent to the top edge of the chuck positioning portion (53), so that the flexible sheet (70) is smoothly passed through the through slot (54), and further through the slot ( 54) an open end is provided with a gas tight ring (56); further, the suction cup positioning portion (53) is provided with a fixing screw (57) relative to the plate body (40); Yes, when the suction pipe (43) When the T-shaped chute (41) is evacuated, the flexible piece (70) is more closely covered by the T-shaped chute (41) due to the pressure difference, so that the T-shaped chute (41) becomes The air chamber, together with the vent hole (52) and the air suction passage (55), can cause the suction cup (60) to have a absorbing effect, so as to suck the plate member.

Based on the configuration, the plurality of sliding bodies (50) of the present invention are embedded in the T-shaped chute (41) of the plate body (40) by the T-shaped rail portion (51), and thus can be along the T shape. The chute (41) is free to move axially, and is further fixed by the fixing screw (57), that is, the suction cup (60) positioned at the bottom edge of the suction cup positioning portion (53) can be adjusted, and the suction cup position can be adjusted. Further, the suction pipe of the present invention has only the exhaust pipe (43) connected to the air suction unit, and has the pure effect of the air suction pipe.

To sum up, the technical means disclosed in the present invention have the invention patents such as "novelty", "progressiveness" and "available for industrial use", and pray for the patent to be invented by the bureau. German sense.

The drawings and the descriptions of the present invention are merely preferred embodiments of the present invention, and those skilled in the art, which are subject to the spirit of the present invention, should be included in the scope of the patent application.
