Adsorption plant
[technical field]
The utility model relates to the equipment of transmission lightweight sheet-like article, especially a kind of adsorption effect good adsorption device.
[background technology]
In process of production; some lightweight sheet materials need transmit between the different stations (for example in the lithium cell production process; when protective tapes is pasted on pole piece surface or the end of electric core paste and pay when stopping adhesive tape, need to be transferred to the stickup station after adhesive tape cutting from the tape roll is got off.), adopt the adsorption plant that is communicated with vacuum system to carry out the transmission of adhesive tape in the prior art mostly, Fig. 1 shows a kind of adsorption plant of the prior art, an end of adsorption plant is laterally cut open among Fig. 1, adsorption plant is provided with vacuum chamber 163 that is communicated with vacuum system and the pore 164 that is communicated with vacuum chamber 163, and pore 164 is opened on the adsorption plane 160 of adsorption plant; Pore 164 can hold adhesive tape when vacuum chamber 163 vacuumized, and can discharge adhesive tape when not vacuumizing.Adsorption plant utilizes vacuum that the adhesive tape that cuts is held, and adsorption plant moves to the stickup station then, and adsorption plant stops to vacuumize and adhesive tape is discharged.The area that this adsorption plant contacts with adhesive tape is bigger, is unfavorable for discharging adhesive tape, particularly when adhesive tape with sticky surface under the mode of adsorption plant and situation that adsorption plant contacts, adhesive tape will stick on the adsorption plant, more be difficult to release.
[utility model content]
Technical problem to be solved in the utility model provides a kind of adsorption effect good adsorption device.
For solving the problems of the technologies described above, the utility model provides a kind of adsorption plant, comprises adsorption plane and the pore that can be communicated with air system, and air vent openings is on adsorption plane; Adsorption plane is provided with boss, and air vent openings is in the table top of boss or be opened on the close region of boss.Like this, the contact surface of adsorption plant and absorbate is the table top of boss, and the area of contact between adsorption plant and the absorbate only is the footprint of boss, and the area of contact between adsorption plant and the absorbate significantly reduces, and helps discharging absorbate.Even absorbate is an adhesive tape, adhesive tape contacts with adsorption plant in the mode of sticky surface towards adsorption plant, adhesive tape adherence force on the adsorption plant also a little less than.
On this basis, further,
As improvement of the present utility model, boss is an annular.This makes the area of contact between adsorption plant and the absorbate further reduce.
Further improve as the utility model, the number of boss is two or more; Be provided with less boss in the bigger boss.Further, each boss forms the boss combination of arranging (small boss is arranged in big boss, arranges in turn according to size) according to big or small ring set; Air vent openings is on the adsorption plane between each boss.Being equipped with like this, stoma number neither can be very little, and the position relation between pore and the boss also relatively rationally.The number of boss combination can be two or more.
In the boss combination, the opening of pore can be set also on the adsorption plane in the endocyclic area of the boss of innermost layer.
Further improve as the utility model, a part is a gas hole for suction hole, another part in the pore.Suction hole is air-breathing during adsorbate, and gas hole is blown when putting absorbate, and such adsorption plant not only adsorbate is firm, and can successfully discharge absorbate.
The beneficial effects of the utility model are: reduce the area of contact between adsorption plant and the absorbate, helped the release of absorbate, and simple in structure, implement easily, easy to use.

[specific embodiment]
Embodiment one
Fig. 2 shows a kind of embodiment of the present utility model.
This adsorption plant can be used for the transfer of adhesive tape in the lithium cell production process.
As shown in Figure 2, this adsorption plant comprises three boss combinations 1 being located on the adsorption plane 160, each boss combination 1 is made up of circular small boss 131 and circular big boss 132, small boss 131 is in the same place with big boss 132 ring sets, be provided with suction hole 134 in the middle of the small boss 131, be provided with two gas holes 133 in the groove between small boss 131 and the big boss 132.Suction hole 134 can be communicated with vacuum system and vacuumize and hold adhesive tape, and gas hole 133 can be communicated with air compression system and outwards blow adhesive tape is discharged.
During use, the area of contact of this adsorption plant and adhesive tape is less, only is the table top of small boss 131 and big boss 132, even adhesive tape contacts with adsorption plant in the mode of sticky surface towards adsorption plane 160, adhesive tape adherence force on the adsorption plant also a little less than, be convenient to adhesive tape and discharge.When adhesive tape with sticky surface under the mode of adsorption plane 160 and situation that adsorption plant contacts, gas hole 133 outside air blowings can help adhesive tape to break away from adsorption plane 160 when discharging adhesive tape, reduce the influence of adhesive tape viscosity to the adhesive tape transfer.Boss combination 1, gas hole 133 and suction hole 134 in this adsorption plant structure can guarantee the reliability that adhesive tape shifts.
Embodiment two
Fig. 3 shows second kind of specific embodiment of the present utility model.
As shown in Figure 3, the adsorption plane 160 of this adsorption plant is provided with three big boss 132 of continuous square frame shape, adjacent two big boss 132 shared limits; In the zone of each big boss 132, adsorption plane 160 is provided with circular small boss 131, is provided with suction hole 134 in the middle of the small boss 131; Each square frame interior angle of big boss 132, adsorption plane 160 is provided with gas hole 133.
The condition of service of this adsorption plant is identical with embodiment one.
Embodiment three
Fig. 4 shows the third specific embodiment of the present utility model.
As shown in Figure 4, the adsorption plane 160 of this adsorption plant is provided with the big boss 132 of square frame shape, and in the zone of big boss 132, adsorption plane 160 is provided with three circular small boss 131, is provided with suction hole 134 in the middle of the small boss 131; Around each square frame interior angle of big boss 132 and middle that small boss 131, adsorption plane 160 is provided with gas hole 133.
The condition of service of this adsorption plant is identical with embodiment one.
In above each embodiment, each small boss 131, big boss 132 all are arranged in a row.The boss that can be as required during concrete enforcement duplicates among above each embodiment with the particular case of tape width is arranged, and adopts two or more arrangements.
Can adopt more boss combination when specifically implementing the utility model according to the length of adsorption plant; Adsorption plant also can adsorb and shifts adhesive tape more than two sections or two sections.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
