Detailed description of the invention

Figure 1A, 1B and 1C illustrate respectively according to vacuum sucking device three-view diagram of the present utility model.Fig. 1 D and 1E illustrates respectively according to the exploded view and overlook exploded view looked up of the present utility model.As shown in Figure 1A-1E, vacuum sucking device 1 comprises: have the cavity 10 of suction openings 100 and have multiple through hole 111a, 111b, the dividing plate 11 of 111c, wherein through hole 111a is arranged in most peripheral, through hole 111b is arranged in the first time periphery inner relative to through hole 111a, and through hole 111c is arranged in the second time periphery inner relative to through hole 111b.The shape of cavity 10 can be cube, cylinder etc.Suction openings 100 can be positioned at one end of cavity 10, can be entered the inner space of cavity 10 by suction openings more than 100 article successively.Cavity 10 wall can be obtained by forming processs such as such as casting, machinework and parts assemblies; It needs to have certain mechanical strength, not deform when receiving above-mentioned article.Dividing plate 11 to be arranged in cavity 10 and cavity 10 to be divided into sky room 101 and the suction chamber 102 being communicated with suction openings 100.Dividing plate 11 can by such as the same being tightly connected or being fixedly connected with by the inwall of integrally casting with cavity 10 of welding, the empty room 101 that dividing plate 11 and cavity 10 cross away from the part of suction openings 100 is connected vacuum generator by gas circuit, thus can form negative pressure in empty room 101.Such as, have bleeding point 103 at the cavity wall relating to sky room 101, vacuum generator deflates from empty room 101 by bleeding point 103, and the air pressure of the room 101 that makes to have leisure is lower than the air pressure of its outside.Multiple article of arranged stacked can be received in the inner space of the suction chamber 102 that the part that dividing plate 11 and cavity 10 close on suction openings 100 crosses.In empty room 101 when negative pressure, can pick and place in the cycle at single, capture in the suction chamber that can be implemented in vacuum sucking device during pickup article and hold multiple article, the stacked stratiform of article is piled up.Once place after so just realizing repeatedly picking up in the process of carrying, reduce haulage equipment reciprocating path between pickup and placement location, thus improve pickup beat.

Best, as shown in Figure 1A-1E, suction chamber 102 inside face has the gas guide groove 104 that many stretch to sky room 101.Gas guide groove 104 can be formed at the suction chamber 102 inside face place of cavity 10 by the technique that such as integrally casting is the same.The top 104a of the protuberance of many gas guide grooves also limits the absorption guide channel leading to suction openings 100 with by the contoured fit being drawn article.Such as, if be the such article of the packed medicine of rectangle for its profile, the top 104a of the protuberance of many gas guide grooves can coordinate in a contact fashion with the contour shape of packed medicine (rectangle), it can enter the motion track of constraint article after suction chamber 102 by article in suction process, thus is limited to and leads in the absorption guide channel of suction openings 100.Alternatively, if be the such article of the biscuit of rectangle for its profile, the top 104a of the protuberance of many gas guide grooves can coordinate in a contact fashion with the contour shape of biscuit (rectangle or circle), it can enter the motion track of constraint article after suction chamber 102 by article in suction process, thus is limited to and leads in the absorption guide channel of suction openings 100.Multiple through hole 111a of dividing plate 11, form gas circuit between 111b, 111c and many gas guide grooves 104, and the part in gas circuit is positioned at outside absorption guide channel.As shown in Figure 1A-1E, guide channel covers through hole 111b, 111c, and does not cover the through hole 111a being in periphery.Alternatively, form gas circuit between first group of through hole 111a and many gas guide grooves 104 to be positioned at outside described absorption guide channel P, and second group of through hole 111b, form gas circuit between the 3rd group of through hole 111c and many articles of gas guide grooves 104 and be positioned within described absorption guide channel.Dividing plate 11 only has multiple through hole 111a being in periphery, and guide channel does not cover the through hole 111a being in periphery, and the gas circuit formed between multiple through hole 111a of dividing plate 11 and many gas guide grooves 104 is all positioned to be drawn outside guide channel.Vacuum sucking device indoor design has gas guide groove, makes the article guaranteeing the bottom during picked multi-layer articles in vacuum sucking device cavity also can be formed into enough vacuum pressure differential with the external world, article can not be dropped when haulage equipment high-speed motion.

Best, multiple through holes of dividing plate are divided at least one group, and the multiple via arrangement often organized are on the pattern concentric and similar to the plane section profile drawing guide channel.Multiple through holes of dividing plate 11 are divided into three groups, i.e. first group of through hole 111a, second group of through hole 111b, the 3rd group of through hole 111c.First group of through hole 111a, second group of through hole 111b, the 3rd group of through hole 111c is disposed on the pattern concentric and similar to the plane section profile drawing guide channel P.Multiple through holes of dividing plate 11 are divided into one group, i.e. first group of through hole 111a.First group of through hole 111a is arranged on the pattern concentric and similar to the plane section profile drawing guide channel P.Above-mentioned layout ensure that by the article drawn can uniform stressed, reduce the probability dropped.Best, the internal diameter of multiple through hole is identical; It further ensures by the article drawn can uniform stressed, reduce the probability dropped.

In order to form negative pressure in empty room 101, empty room 101 wall of cavity 10 has at least one vacuum pumping opening.Vacuum generator is communicated with vacuum pumping opening.

In order to be connected with robot, cavity 10 outside face of vacuum sucking device 1 is fixedly connected with flange.

Article lie against in travel line or plane, after starting with the vacuum system of vacuum sucking device, carrying mechanism folder for carrying from directly over successively near article, article are inhaled in fixture cavity successively.Fixture moves to the position of placement after being filled multiple article, now vacuum system stops, and article drop in the position of placement.Fig. 2 A and 2B illustrates the different conditions according to vacuum sucking device of the present utility model successively.State shown in Figure 1A draws article for preparing, and owing to forming negative pressure in empty room 101, at first group of through hole 111a, second group of through hole 111b, the 3rd group forms air-flow (shown in arrow) between through hole 111c and suction chamber 102.State shown in Fig. 2 A is absorption article M1, owing to forming negative pressure in empty room 101 and at first group of through hole 111a, second group of through hole 111b, 3rd group forms air-flow (shown in arrow) between through hole 111c and suction chamber 102, it is covered second group through hole 111b, three group through hole 111c by sticking to dividing plate 11 through drawing guide channel.State shown in Fig. 2 B draws article M1 for continuing.Because article M1 covers second group of through hole 111b, 3rd group of through hole 111c, due to form negative pressure in empty room 101 and in first group of through hole 111a and suction chamber 102 but being in draw outside guide channel P forms air-flow (shown in arrow), its through absorption guide channel P by sticking and with article M1 arranged stacked.Utilize identical principle, vacuum sucking device can draw more article M2, and M3, M4 pile up in suction chamber stackedly.

Although illustrate and describe the utility model with reference to some preferred embodiment of the present utility model, but it will be appreciated by those skilled in the art that, when not deviating from spirit and scope of the present utility model as defined in appended claims, can make a variety of changes it in the form and details.
