Description

Adsorption unit, method for manufacturing adsorption unit, and adsorption device

The present invention relates to an adsorption unit, a method for manufacturing an adsorption unit, and an adsorption device, and more particularly, to an adsorption unit capable of maintaining strong adsorption force even for a spherical object or an amorphous object, a method for manufacturing an adsorption unit, and an adsorption device.

The adsorption device is a device for adsorbing and holding a holding object using a negative pressure applied by a vacuum pump. In general, an adsorption device is installed and used in a transport device for transporting articles.

Depending on the size of the object to be adsorbed, a single adsorption pad or a plurality of adsorption pads are used in the adsorption device.

When a single suction pad is used, there is a problem in that suction is impossible because it is difficult to generate an absorption force in the case of an object having a hole through the area in contact with the suction pad. Of course, in order to solve this problem, a small suction pad may be used to attach to a portion avoiding the penetrating area of the object to be absorbed.

On the other hand, in order to stably adsorb an object, a soft adsorption pad is used. However, such a suction pad has a problem in that it cannot maintain a strong absorption force for a spherical object or an amorphous object.

Figure 1 is a perspective view showing an adsorption unit according to a first embodiment of the present invention, Figure 1 (a) is shown in a state looking down the adsorption unit, Figure 1 (b) is a state looking up at the adsorption unit it has been shown And, FIGS. 2 and 3 are exploded perspective views of the adsorption unit of FIG. 1 .

1 to 3 , the adsorption unit 1000 may include a flexible adsorption pad 100 and a support unit 200 .

The flexible suction pad 100 may have a plurality of suction cells 120 that are partitioned and formed by the flexible partition wall 110 . An object to be adsorbed may be in contact with the front end of the flexible adsorption pad 100 .

The support unit 200 includes a base 210 coupled to the rear end of the flexible suction pad 100 and a connection hole formed to protrude from the base 210 and inserted into each of the suction cells 120 and communicate with the suction cells 120 . It may have a socket 220 in which 221 is formed. When the negative pressure provided from the outside is transferred to the suction cell 120 through the connection hole 221 , the contacted object to be absorbed may be adsorbed to the flexible suction pad 100 . The support unit 200 may support the coupled flexible suction pad 100 .

In detail, the flexible suction pad 100 may have a plurality of suction cells 120 partitioned by the flexible partition wall 110 .

The partition wall 110 may be formed of a flexible material, and the suction cell 120 partitioned by the partition wall 110 may be formed so that both ends are open.

The front end of the flexible suction pad 100 may be in contact with the target object, and the internal negative pressure of the suction cell 120 may be controlled by the negative pressure control unit 500 so that when a suction force is generated, the suction target is the flexible suction pad (100) can be adsorbed.

The partition wall 110 may be formed of a material through which air does not pass. For example, the flexible adsorption pad 100 may be formed of a flexible polymer material. Therefore, the air sucked into one suction cell 120 cannot pass through the partition wall 110 and move to another suction cell 120.

The partition walls 110 between the suction cells 120 may all have the same thickness. In addition, the suction cell 120 may be a polygonal shape having the same shape and size of a cross-section perpendicular to the central axis direction of the suction cell 120 . The polygonal shape may be, for example, any one of a triangle, a square, and a hexagon. In the present invention, the hexagonal shape is described, and according to this, the flexible suction pad 100 may be in the form of a honeycomb. Since the suction cell 120 is partitioned by the thin barrier rib 110 , the empty space between the suction cells 120 is reduced, so that the overall absorption area can be increased, and the absorption efficiency can be increased. In particular, since the suction cell 120 is formed to have a hexagonal cross-section, when the suction cell 120 is pressed by an object to be absorbed, the shape of the suction cell 120 collapses and the suction cell 120 is clogged. This phenomenon can be effectively prevented.

And, the adsorption unit 1000 may include a flexible support (180). The flexible support 180 may be provided in the inner space of the suction cell 120 . When defining the direction perpendicular to the axial direction (A1) as the width direction with respect to the axial direction (A1) of the suction cell (120), the flexible support body (180) is more rigid than the axial direction (A1) of the suction cell (120) It can have a large width direction stiffness. Through this, even when the partition wall 110 is depressed and deformation in the width direction of the suction cell 120 occurs, the flexible support 180 provides resistance to the contraction deformation in the width direction of the suction cell 120 to the suction cell 120 . This can be prevented from being closed, and through this, it is possible to stably generate an adsorption force for an object to be adsorbed.

The flexible support 180 may be a coil spring in contact with the inner circumferential surface of the suction cell 120 . The coil spring may be wound in a circular shape, but is not necessarily limited thereto, and may be formed in a shape corresponding to the cross-sectional shape of the suction cell 120 in the width direction. That is, when the cross-section in the width direction of the suction cell 120 is hexagonal, the coil spring may also be formed in a hexagonal shape.

A coupling hole 130 connected to the suction cell 120 may be formed through the rear end of the flexible suction pad 100 . The coupling hole 130 may be formed smaller than the cross-sectional size of the suction cell 120 , but is not necessarily limited thereto, and may be formed to correspond to the cross-sectional size of the suction cell 120 .

In addition, a flange 140 may be provided at the rear end of the flexible suction pad 100 .

In addition, a seating groove 160 may be formed in the center of the flange 140 . The coupling hole 130 may be exposed rearwardly through the seating groove 160 .

The support 200 may have a base 210 and a socket 220 .

The base 210 may be formed to correspond to the flange 140 , and the rear surface 142 of the flange 140 may be in close contact with the front surface 211 of the base 210 .

The socket 220 may be formed to protrude from the front of the base 210 , and may be inserted into the suction cell 120 . In this embodiment, the socket 220 may be formed in a number corresponding to the number of the suction cells 120 , and may be inserted into each suction cell 120 . The socket 220 may have a connection hole 221 penetratingly formed in the central axis direction. When the socket 220 is inserted into the suction cell 120 , the connection hole 221 may be connected to the inside of the suction cell 120 .

The socket 220 may be formed to have a diameter greater than or equal to the diameter of the coupling hole 130 . Since the flexible suction pad 100 is formed of a flexible material, it can have elasticity, and therefore, even if the diameter of the socket 220 is larger than the diameter of the coupling hole 130 , the socket 220 is opened by opening the coupling hole 130 . It can be inserted, and through this, it is possible to prevent air leakage between the suction cell 120 and the socket 220 .

As the socket 220 is inserted into the suction cell 120 and the diameter of the connection hole 221 is formed smaller than the diameter of the suction cell 120, the internal space volume of the suction cell 120 can be reduced, and this Through this, it is possible to form a stronger suction force.

The support unit 200 may further include a protrusion 230 protruding from the front surface 211 of the base 210 . The protrusion 230 may be formed to correspond to the seating groove 160 of the flexible suction pad 100 . When the socket 220 is inserted into and coupled to the suction cell 120 , the protrusion 230 may also be inserted into the seating groove 160 . At this time, the front surface of the protrusion 230 may be in close contact with the bottom surface of the seating groove 160 to prevent air leakage between the seating groove 160 and the protrusion 230 .

A ring groove 240 may be formed in the rear surface 212 of the base 210 , and an airtight ring (not shown) may be inserted into the ring groove 240 . In addition, a first through hole 213 may be formed in each corner of the base 210 .

The adsorption unit 1000 may have a coupling ring 300 and a cover part 400 .

The coupling ring 300 may be formed to correspond to the flange 140 of the flexible suction pad 100 , and a through portion 310 may be formed in the center. The rear surface 301 of the coupling ring 300 may be in close contact with the front surface 141 of the flange 140 , and the flexible suction pad 100 may be positioned through the through portion 310 of the coupling ring 300 . have.

A second through hole 320 may be formed at an edge of the coupling ring 300 to correspond to the first through hole 213 . The fastening member 350 may be coupled to the first through hole 213 through the second through hole 320 , and through this, the coupling ring 300 may be coupled to the support unit 200 . The flange 140 of the flexible suction pad 100 may be compressed between the base 210 and the coupling ring 300 of the support 200, and through this, between the flexible suction pad 100 and the support 200. Air leakage can be prevented.

The cover part 400 may have an adhesion plate 410 , a hood 420 , and a through hole 430 .

The adhesion plate 410 may be formed to correspond to the base 210 of the support 200 . The front surface 411 of the adhesion plate 410 may be in close contact with the rear surface 212 of the base 210, and between the base 210 and the adhesion plate 410 by an airtight ring coupled to the ring groove 240 is may be confidential.

The hood 420 may be formed above the adhesion plate 410 and may be connected to the through hole 430 . In addition, the through hole 430 may be connected to the negative pressure control unit 500 .

The negative pressure control unit 500 may control a negative pressure of the suction cell 120 . That is, when the negative pressure control unit 500 generates a suction force, the air inside the suction cell 120 escapes through the connection hole 221 and the hood 420 of the socket 220, the suction cell 120 A suction force may be generated inside. Therefore, when the negative pressure control unit 500 generates a negative pressure in the suction cell 120 in a state in which the object to be absorbed is in contact with the front end of the flexible suction pad 100 , a suction force is generated in the suction cell 120 , and accordingly The object to be adsorbed may be adsorbed to the front end of the flexible adsorption pad 100 .

A third through hole 412 corresponding to the first through hole 213 may be formed at a corner of the contact plate 410 . The fastening member 350 may be coupled to the third through hole 412 through the second through hole 320 and the first through hole 213 , and through this, the coupling ring 300 , the flexible suction pad 100 . ), the support part 200 and the cover part 400 may be combined.

4 is an exploded cross-sectional view of the flexible adsorption pad and the support of the adsorption unit of FIG. 1 , FIG. 5 is an exemplary view schematically illustrating an assembly cross-section of the adsorption unit of FIG. 4, and FIG. 6 is the operation of the adsorption unit of FIG. It is an example diagram. 4 to 6, the flexible adsorption pad 100 and the support unit 200 are simplified and shown briefly.

The first interval P1 between the centers of the suction cell 120 may be shorter than the second interval P2 between the centers of the socket 220 (see FIG. 4A ). Therefore, in order to insert the socket 220 into the suction cell 120, a tensile force is applied to the rear end of the flexible suction pad 100 so that the rear end of the flexible suction pad 100 is elongated (F), so that the first interval (P1) It can be made equal to this second interval P2 (refer to FIG. 4(b)). And, the socket 220 may be inserted into the suction cell 120 in a state in which the rear end of the flexible suction pad 100 is extended in this way. When the tensile force is removed after the socket 220 is inserted into the suction cell 120, the suction cell 120 and the socket 220 are in close contact and firmly fixed to each other by the elastic restoring force of the flexible suction pad 100. .

On the other hand, when the socket 220 is inserted into the suction cell 120 in a state in which the rear end of the flexible suction pad 100 is extended, the flexible suction pad 100 is deformed in shape so that the cross-sectional area becomes smaller toward the front end 121 . can be provided. And, the front end 121 of the flexible suction pad 100 may be provided in a concave shape (see FIG. 5 ), and through this, the flexible suction pad 100 may have the effect of a suction cup.

Specifically, as shown in (a) of Figure 6, when the adsorption target object 10 is formed to be round, such as an oval or a circle, the adsorption target object 10 is the front end 121 of the flexible suction pad 100. When in contact with, the gap (G) between the front end 121 of the flexible suction pad 100 and the target object 10 may be small. That is, as the front end 121 of the flexible suction pad 100 is concavely formed, the central suction cell 120a may be easily in close contact with the absorption target object 10 . And, although the suction cell 120b at the edge is not in close contact with the object 10 to be absorbed, the distance G therebetween may be reduced.

Accordingly, when a suction force is generated inside the suction cell 120, the suction cell 120b at the edge can be wrapped around the suction target object 10 while being more easily adhered to (see FIG. 6(b)). ). That is, the surface area of the suction cell for adsorbing the object to be adsorbed 10 may be increased, and thus, the object to be adsorbed 10 may be more strongly adsorbed. When the suction cell 120 is pressed by the suction target object 10, the flexible support 180 may also be deformed in shape, but the flexible support 180 has resistance to the widthwise shrinkage deformation of the suction cell 120. By providing it, it is possible to prevent the suction cell 120 from being closed, and the absorption force can be stably applied to the object 10 to be absorbed.

The flexible support 180 may be inserted into the suction cell 120 after the coupling of the flexible suction pad 100 and the support 200 is completed. Alternatively, the flexible support 180 is first inserted into the suction cell 120, and then, the flexible suction pad 100 and the support 200 may be coupled.

As shown in FIG. 7 , only the socket 220a provided at the edge of the support 200 and having the connection hole 221a may be disposed. In addition, only the connection hole 221b may be formed in a portion other than this without a socket.

Even in this case, the flexible suction pad coupled to the socket 220a provided at the edge may be fixed in an extended state, and the time required for the coupling process of the socket and the suction cell may be reduced.

In addition, a socket 220b provided in the central portion of the support 200 and having a connection hole 221c may be further disposed. The number of sockets 220b provided in the central portion is not particularly limited, and the number may be appropriately selected according to the size of the support 200 and the flexible suction pad 100 .

11, when a negative pressure is provided through the connection line 600 and a suction force is generated in the suction cell, the air SA is sucked by the suction force, and the ball 705 moves in the direction of the stopper 706. will be pushed to Then, the elastic member 707 is compressed, the through-hole 704 is opened, and when the suction force is continuously provided, the object 10 to be adsorbed may be continuously adsorbed to the corresponding suction cell. Then, when the suction target object 10 completely seals the suction cell, there is no air flow to be sucked in, and the line becomes a vacuum state, and the ball 705 is formed through the through hole 704 by the elastic restoring force of the elastic member 707 . ) will be blocked.

On the other hand, when the air flow rate sucked into each suction cell in the state where the target object 10 is not adsorbed to the flexible suction pad 100 is the first flow rate, as described above, the suction cell on which the target object is adsorbed. Since the ball 705 blocks the through hole 704 so that no air flow occurs, a second flow rate with a large first flow rate is generated in the suction cell in which the object to be adsorbed is not adsorbed. Then, as shown in FIG. 12 , the elastic member 707 is further compressed and the ball 705 can seal the stopper 706 .

The second flow rate may be preset as a suction flow rate for closing the check valve 700, and thus, when a suction flow rate exceeding the preset suction flow rate occurs, the check valve 700 may be closed. . Through this, the check valve provided in the connection line connected to the suction cell to which the object to be adsorbed is not adsorbed among the check valves may be closed by the suction force of the suction cell. When the suction of air is not made in all suction cells formed on the flexible suction pad 100 , the target object 10 may be more strongly adsorbed to the suction cell that is adsorbed.
