Description

Technical Field

[0001] The utility model relates to the technical field of automation, in particular to a partitioned vacuum platform. Background Art

[0002] A vacuum adsorption platform is a device that uses vacuum technology to adsorb objects and make them stick to the surface. It creates a negative pressure environment so that the object is affected by atmospheric pressure and sticks to the adsorption platform. The vacuum adsorption platform usually consists of a vacuum chamber and an adsorption plate. When the pressure in the vacuum chamber drops to a certain level, the suction cup on the adsorption plate will form negative pressure, thereby adsorbing the object. Since the vacuum adsorption platform uses negative pressure to adsorb objects, it causes less damage to the object and can be used safely and reliably in various application scenarios.

[0003] The existing vacuum platforms all have only one vacuum chamber and one vacuum source. The existing vacuum platforms are universal and compatible with products of the largest specifications. Therefore, when sucking non-large products, that is, when the large vacuum platform sucks small products, there are air leaks around, which makes the vacuum degree very low, and thus the product cannot be sucked tightly.

[0029] A vacuum adsorption platform is a device that uses vacuum technology to adsorb objects and keep them in the air. It creates a negative pressure environment so that the object is affected by atmospheric pressure and sticks to the adsorption platform. The vacuum adsorption platform usually consists of a vacuum chamber and an adsorption plate. When the pressure in the vacuum chamber drops to a certain level, the suction cup on the adsorption plate will form a negative pressure, thereby adsorbing the object. Since the vacuum adsorption platform uses negative pressure to adsorb objects, it causes less damage to the object and can be used safely and reliably in various application scenarios.

[0030] The existing vacuum platforms all have only one vacuum chamber and one vacuum source. The existing vacuum platforms are universal and compatible with products of the largest specifications. Therefore, when sucking non-large products, that is, when the large vacuum platform sucks small products, there are air leaks around, which makes the vacuum degree very low, and thus the product cannot be sucked tightly.

[0031] In view of this, the utility model provides a partitioned vacuum platform 100. Figure 1 to Figure 2 This is an embodiment provided by the utility model.

[0032] See also Figure 1 and Figure 2 , is a schematic diagram of an embodiment of the utility model, which proposes a partitioned vacuum platform 100, including a marble slide 2, an adsorption plate 1 and multiple vacuum sources, the adsorption plate 1 is provided with multiple adsorption holes 122, the adsorption plate 1 is covered on the marble slide 2, a surface of the adsorption plate 1 is provided with multiple partitions 13, the multiple partitions 13 separate the marble slide 2 and the adsorption plate 1 into multiple vacuum areas, multiple vacuum areas are provided with ventilation holes 15, multiple vacuum sources are connected to exhaust pipes 11, and the multiple exhaust pipes 11 pass through the multiple ventilation holes 15 one by one and extend to the inside of the multiple vacuum areas.

[0033] In the technical solution provided by the utility model, a plurality of vacuum areas are separated between the marble slide 2 and the adsorption plate 1 by a plurality of the partition bars 13, so that each of the vacuum areas can adsorb a small part of the product, and the entire product can be adsorbed by the joint adsorption of the plurality of vacuum areas, and the corresponding vacuum area can be selected according to the placement position of the product to achieve the selection of the vacuum area. The adsorption of the product will not be unable to be completed due to damage to one vacuum area, and the adsorption of the product can be completed by selecting suitable and as few vacuum areas as possible. At the same time, the space occupied by the vacuum area is obviously smaller than the space occupied by only one vacuum area. One end of the exhaust pipe 11 is in the vacuum area, and the other end is connected to the vacuum source. Due to the small occupied space, the energy consumed will naturally be reduced, and the adsorption of the product can be completed with less energy, thereby avoiding the situation where a large vacuum area adsorbs a smaller product, causing air leaks in the surrounding area and affecting the vacuum degree, preventing excessive adsorption, reducing unnecessary waste, and saving costs.

[0034] In one embodiment, at least part of the vent holes 15 are disposed on the marble slide 2 , and / or at least part of the vent holes 15 are disposed on the adsorption plate 1 . In order to make the multiple vacuum areas between the marble slide 2 and the adsorption plate 1 have the adsorption function, it is necessary to use multiple vacuum sources to evacuate the multiple vacuum areas respectively, so it is necessary to extend the multiple exhaust pipes 11 connected to the multiple vacuum sources to the multiple vacuum areas respectively for exhausting. At this time, it is necessary to open the vent holes 15 for the multiple exhaust pipes 11 to penetrate on the marble slide 2 or the adsorption plate 1. Of course, the marble slide 2 and the adsorption plate 1 can also open the vent holes 15 together; the multiple vent holes 15 can appear at the bottom of the marble slide 2, and can be opened at any position of the corresponding vacuum area at the bottom of the marble slide 2, and only a shorter exhaust pipe 11 is required; the multiple vent holes 15 only need to be opened on the side of the adsorption plate 1, and the arrangement is relatively simple; the multiple vent holes 15 are opened on both the marble slide 2 and the adsorption plate 1, which can be suitable for a variety of different occasions and space needs to achieve the adsorption function of multiple vacuum areas.

[0035] In one embodiment, a plurality of the partition bars 13 are vertically connected to each other to enclose a plurality of rectangular areas 14, and the partition bars 13 between the plurality of the rectangular areas 14 are provided with openings 131 to interconnect the plurality of the rectangular areas 14 in the same vacuum area. By providing a plurality of the rectangular areas 14, several of the rectangular areas 14 can be connected to form a vacuum area according to needs, and no matter whether the vacuum area is small or large, or no matter what shape the vacuum area is, the corresponding rectangular areas 14 can be connected, that is, only the openings 131 are provided on the partition bars 13 between the plurality of adjacent rectangular areas 14, so that the formation of the vacuum area can be conveniently and simply, the difficulty of forming the plurality of vacuum areas can be reduced, and the cost can be saved.

[0036] Furthermore, the plurality of vacuum areas include a first vacuum area formed by at least one rectangular area 14 at a corner of the adsorption plate 1, and the other plurality of vacuum areas extend in sequence in a direction gradually away from the first vacuum area, and the partition bars 13 between each two adjacent rectangular areas 14 in the other vacuum areas are provided with the openings 131 and form an L-shaped connecting portion. The L-shaped connecting portion enables the plurality of rectangular areas 14 to form a plurality of L-shaped vacuum areas, and the L-shaped vacuum areas can jointly adsorb the parts of the product in two directions perpendicular to each other, so that even one L-shaped vacuum area can firmly adsorb the larger product, and the product can be more firmly adsorbed by the two L-shaped vacuum areas adsorbed on both sides of the product respectively, and the effect of adsorbing a larger product area with less energy consumption can be achieved through the cooperation of one or more L-shaped vacuum areas.

[0037] In addition, a first groove is provided on the outer surface of the adsorption plate 1 close to the marble slide 2, and a plurality of communication ports 121 are provided on the side wall of the first groove, which are connected to the plurality of rectangular areas 14 in a one-to-one correspondence, and a plurality of adsorption holes 122 are evenly distributed on the bottom of the first groove. The communication ports 121 can connect the first groove with the plurality of vacuum areas to complete the air extraction of the first groove, thereby making the first groove also have an adsorption function, and a plurality of adsorption holes 122 are evenly distributed on the bottom of the first groove, which can increase the number of adsorption holes 122 on the adsorption plate 1, so that the edges around the adsorption plate 1 also have a plurality of adsorption holes 122, and the first groove and the plurality of adsorption holes 122 can further increase the adsorption capacity and adsorption range of the adsorption plate 1.

[0038] Furthermore, the first groove includes a plurality of second grooves 12 arranged at intervals in the direction in which the first groove extends, the side walls of the plurality of second grooves 12 are each provided with a communication port 121 corresponding to and connected to one of the plurality of rectangular areas 14, and the bottom of the second groove 12 is evenly distributed with a plurality of adsorption holes 122. By providing a plurality of second grooves 12 arranged at intervals in the direction in which the first groove extends, the adsorption capacity and adsorption range of the adsorption plate 1 can be increased while the mechanical strength of the adsorption plate 1 can be enhanced.

[0039] In one embodiment, the adsorption plate 1 is threadedly connected to the marble slide 2. By connecting the threaded nut and the bolt together, the adsorption plate 1 and the marble slide 2 are fixed, so that the connection between the adsorption plate 1 and the marble slide 2 is more reliable and the disassembly and assembly are more convenient.

[0040] In one embodiment, the plurality of vacuum sources include a vacuum generator. The vacuum generator is a device that generates negative pressure using a positive pressure gas source, and creates a vacuum environment by extracting air. Since the partitioned vacuum platform 100 has a plurality of vacuum areas to complete adsorption, the vacuum flow rate of each vacuum area is not large, and the vacuum generator is used as a vacuum source, so that the vibration is very small, and it is particularly suitable for precise positioning occasions.

[0041] In one embodiment, the flatness of the adsorption plate 1 is A, A≤0.05 mm. This arrangement allows the product to be placed more flat on the adsorption plate 1, and also allows the product to be adsorbed more flatly on the adsorption plate 1, and meets the need for high-precision positioning.

[0042] In one embodiment, the same L-shaped plate 3 is correspondingly attached to both sides of the adsorption plate 1 and the marble slide 2. By providing the L-shaped plate 3, the product can be completely adsorbed on the adsorption plate 1 to prevent the adsorbed product from warping.

[0043] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
