[0034] The present invention provides a suction cup structure.

[0035] In the embodiment of the present invention, please refer to Figures 1 to 2 The suction cup structure 10 includes a cover plate 100, a partition plate 200 and a plurality of check members 300. The cover plate 100 is provided with a plurality of vents 100a, and the vents 100a are used to extract vacuum or pass compressed gas. Figure 3 、 Figures 8 and 9 The partition 200 is located on one side of the cover plate 100, and a plurality of vacuum ports 200a are provided on the partition 200. The diameter of the vacuum port 200a is larger than the diameter of the vent 100a. The vacuum port 200a corresponds to the vent 100a one-to-one, and the vent 100a is located inside the vacuum port 200a; the check member 300 is covered on a side of the partition 200 away from the cover plate 100, so that the check member 300 corresponds to the vent 100a and partially blocks the vacuum port 200a.

[0036] For details, please refer to Figure 2 、 Figures 8 and 9 The cover plate 100 is provided with a plurality of vents 100a. The cover plate 100 can be connected to a vacuum assembly or a vacuum emitter. By drawing a vacuum or delivering compressed gas through the vents 100a, a negative pressure is created to adsorb the object. The cover plate 100 and the vacuum assembly or vacuum emitter can be connected directly or indirectly.

[0037] The multiple vents 100a can be evacuated or compressed gas can be emitted by a single vacuum pumping assembly or vacuum emitter, or the multiple vents 100a can be evacuated or compressed gas can be emitted by two vacuum pumping assemblies or vacuum emitters, with one vacuum pumping assembly or vacuum emitter corresponding to some of the vents 100a and the other vacuum pumping assembly or vacuum emitter corresponding to the remaining vents 100a. In other words, the number of vacuum pumping assemblies or vacuum emitters can be one or more.

[0038] Please refer to Figure 2 、 Figures 6 and 7 The cover plate 100 is provided with a partition 200. A vacuum port 200a is provided on the partition 200 at a position corresponding to the vent 100a. The diameter of the vacuum port 200a is larger than that of the vent 100a, so that the vent 100a is located within the vacuum port 200a. When the vacuum assembly or vacuum emitter is in operation, air near the vacuum port 200a is drawn away through the vent 100a, or compressed gas is delivered to the vacuum port 200a through the vent 100a, thereby creating a negative pressure near the vacuum port 200a and sucking objects at the vacuum port 200a.

[0039] It should be noted that the shapes of the vent 100a and the vacuum port 200a are various and can be circular, square or other regular or irregular shapes. The shapes of the vent 100a and the vacuum port 200a can be the same or different. In order to increase the adsorption area and facilitate the adsorption of objects, please refer to Figure 2 In one embodiment, the vent 100a is a round hole, and the vacuum port 200a is a square hole.

[0040] Please refer to Figure 2 、 Figures 6 and 7 The suction cup structure 10 also includes a plurality of check members 300. The check members 300 are arranged on the partition 200 corresponding to the vent 100a and cover the position of the vacuum port 200a. A gap 10a is formed between the check member 300 and the cover 100 in the vacuum port 200a, and the gap 10a is connected to the vent 100a. The air near the opening is extracted through the gap 10a or compressed gas is delivered to the vicinity of the opening, forming a negative pressure near the opening to adsorb the object, thereby reducing the flow of airflow, preventing a large amount of compressed air from leaking or preventing a large amount of gas from being extracted. In other words, the partition 200 cushions the check member 300, forming a gap 10a between the check member 300 and the cover 100 for the flow of gas, thereby preventing the check member 300 from blocking the vent 100a, preventing the gas from being unable to flow and forming a negative pressure. It can be understood that the plurality of check members 300 can be interconnected into one body to form a check plate.

[0041] Please refer to Figure 5 、 Figure 7 and Figure 9 The check piece 300 blocks the vent 100a, and a small amount of gas is drawn from the vacuum port 200a to the vent 100a, or a small amount of compressed gas is transmitted from the vent 100a to the vacuum port 200a, which reduces the gas flow and reduces energy consumption; if there is an object near the vacuum port 200a, the gap between the check piece 300 and the cover plate 100 can also allow gas to flow, forming a negative pressure near the vacuum port 200a, which does not affect the normal adsorption of the object.

[0042] The technical solution of the present invention comprises a partition 200 located on one side of a cover plate 100. The vacuum port 200a of the partition 200 corresponds one-to-one with the vent 100a of the cover plate 100. The vent 100a is located within the vacuum port 200a. A check member 300 is provided to cover the vacuum port 200a of the partition 200, shielding the vent 100a and a portion of the vacuum port 200a. By drawing a vacuum or passing compressed gas through the vent 100a, a negative pressure is generated near the vacuum port 200a, thereby allowing objects to be adsorbed. The number of vents 100a can be the same as the number of vacuum ports 200a, or can be greater than the number of vacuum ports 200a, i.e., one vacuum port 200a corresponds to multiple vents 100a.

[0043] When there are no objects on some of the partitions 200, that is, when there are no objects at some of the vacuum ports 200a, the check member 300 is correspondingly provided above the vent 100a and blocks some of the vacuum ports 200a, thereby reducing the consumption of compressed gas and the extraction of gas. When there are objects on some of the partitions 200, that is, when there are objects at some of the vacuum ports 200a, although the vacuum ports 200a are partially blocked by the check member 300, negative pressure is still formed near the vacuum ports 200a, thereby adsorbing the objects. In this way, the suction cup structure 10 adsorbs the objects in the areas where there are objects, and the amount of vacuum and compressed air in the areas where there are no objects is reduced, thereby reducing energy consumption and costs. Furthermore, there is no need to customize suction cup structures 10 of different sizes according to the size of the adsorbed objects, thereby improving the versatility of the suction cup structure 10.

[0044] The anti-return member 300 can be a hard member or an elastic member. Figure 2 、 Figures 4 and 5 In one embodiment, the check member 300 is made of rubber.

[0045] Rubber is a polymer material with reversible deformation. It is elastic at room temperature and can deform under the action of external force and return to its original shape after the external force is removed. Figures 7 to 9 By adopting the check piece 300 made of rubber material, when the vacuum assembly or vacuum emitter is in operation, there are no objects near some vacuum ports 200a, and vacuum flow is formed near these vacuum ports 200a, causing the check pieces 300 corresponding to the vacuum ports 200a at these positions to deform and bend. The bent check piece 300 blocks part of the vent 100a, and the check piece 300 is adsorbed, further reducing the flow of airflow, preventing a large amount of compressed air from leaking or preventing a large amount of gas from being extracted, thereby achieving the purpose of vacuum check.

[0046] Please refer to Figure 9 When an object is placed near these vacuum ports 200a, the object covers the vacuum ports 200a, and the gap 10a continues to be vacuumed or compressed gas is emitted, so that negative pressure continues to form at the gap 10a. When the pressure of the gap 10a is equal to the pressure of the vent 100a, the check member 300 deforms and bends to restore; continuing to vacuum or emit compressed gas increases the negative pressure at the gap 10a, thereby adsorbing the object. In this way, a large vacuum flow and vacuum pressure are not required, energy consumption is reduced, and the adsorption of the object is achieved. In order for the check member 300 to be adsorbed on the cover plate 100, a gap is formed between the check member 300 and the cover plate 100. The peripheral edge of the vent 100a of the cover plate 100 facing the check member 300 is roughened, and the roughened surface is uneven and can be a frosted surface.

[0047] The shape of the check member 300 is various, and can be a sheet or a block. Figure 2and Figure 5 In one embodiment, the check member 300 is in a sheet-like configuration. By configuring the check member 300 as a sheet-like structure, the check member 300 is easily deformed when subjected to negative pressure, thereby blocking the vent 100a and achieving the purpose of preventing the return.

[0048] The shape of the check member 300 can be circular, triangular, square or other regular or irregular shapes. Figure 2 and Figure 5 In one embodiment, the backstop 300 is square. It can be rectangular or square. If the backstop 300 is too thick, it will be difficult to deform. If it is too thin, it will completely block the vent 100a, making it difficult to restore. To address this issue, in one embodiment, the backstop 300 has a thickness of 0.2 mm to 0.5 mm.

[0049] There are many ways to cover the check member 300 on the partition 200 and block the vent 100a. The check member 300 can be covered on the partition 200, or one end of the check member 300 can be covered on the partition 200 and the other end can be covered on the cover 100, so that a gap 10a is formed between the check member 300 and the cover 100. Figures 4 and 5 、 Figure 7 In one embodiment, opposite ends of the check member 300 are located on the partition plate 200 . In other words, the check member 300 is mounted on the edge of the vacuum port 200 a to form a gap 10 a between the check member 300 and the cover plate 100 .

[0050] Unlike the previous embodiment, in one embodiment, one end of the check member 300 is capped on the partition 200, and the other end is capped on the partition 200. One end of the check member 300 is located on the partition 200, blocking the vent 100a, while the other end of the check member 300 extends from the vacuum port 200a and caps the partition 200, thereby forming a gap 10a between the check member 300 and the partition 200.

[0051] Please refer to Figures 7 and 8 、 Figure 10 In one embodiment, the suction cup structure 10 further includes a bottom plate 400, which is located on a side of the cover plate 100 away from the partition 200. A vacuum groove 400a is provided on the bottom plate 400, and the vacuum groove 400a is connected to the vent 100a; the bottom plate 400 is used to connect a vacuum assembly or a vacuum emitter to evacuate or pass compressed air into the vacuum groove 400a.

[0052] Please refer to Figure 8The vacuum tank 400a is connected to a plurality of vents 100a. When the vacuum tank 400a is evacuated or compressed gas is delivered, negative pressure is formed on the vents 100a and the vacuum ports 200a, thereby adsorbing the objects on the partition 200. Figures 8 to 10 The bottom of the vacuum tank 400a may be provided with a connection port 400b, which is used to insert the vacuum joint of the vacuum assembly or the vacuum joint 20 of the vacuum emitter to reduce the pressure in the vacuum tank 400a and form a negative pressure near the vacuum port 200a.

[0053] To prevent the stopper 300 from falling out or objects from hitting the stopper 300, causing the stopper 300 to shift, please refer to Figure 2 、 Figures 7 and 8 In one embodiment, the suction cup structure 10 further includes a suction plate 500, the suction plate 500 is located on the partition 200, the check member 300 is located between the suction plate 500 and the partition 200, an adsorption gap 600c is formed between the suction plate 500 and the check member 300, and the suction plate 500 is provided with a suction port 500a corresponding to the check member 300.

[0054] Please refer to Figure 2 The suction port 500a on the suction plate 500 is connected to the vacuum port 200a. There are multiple suction ports 500a, and the number of suction ports 500a can be the same as the number of vacuum ports 200a. An object can be placed on the suction plate 500, and a negative pressure is formed at the suction port 500a, thereby adsorbing the object. Gas can flow from the suction port 500a into the vacuum port 200a, pass through the gap 10a, reach the vacuum groove 400a from the vacuum port 200a, and then be extracted from the connecting port 400b; or vice versa, compressed air can flow from the connecting port 400b into the vacuum groove 400a, pass through the vacuum port 200a, reach the gap 10a, flow from the vacuum port 200a to the suction port 500a, form a negative pressure at the suction port 500a, and adsorb the object.

[0055] The suction port 500a may be located at the edge of the stopper 300. Figures 3 and 4 , or the suction port 500a can be located at the position of the check member 300 corresponding to the vent 10a. In order to further improve the flow of air, block the large amount of leakage of compressed air or block the extraction of a large amount of gas, please refer to Figures 8 and 9 In one embodiment, the diameter of the suction port 500a is smaller than that of the vacuum port 200a, the suction port 500a corresponds to the check member 300, and an suction gap 600c is formed between the suction plate 500 and the check member 300 to connect the suction port 500a and the vacuum port 200a.

[0056] To form the adsorption gap 600c, please refer to Figure 2 、 Figures 6 and 7 In one embodiment, the suction cup structure 10 further includes a connecting plate 600, which is positioned between the suction plate 500 and the partition plate 200. The connecting plate 600 has a receiving opening 600a corresponding to the vacuum port 200a. The receiving opening 600a has a larger diameter than the vacuum port 200a. The check member 300 is positioned within the receiving opening 600a, thereby forming the suction gap 600c between the check member 300 and the suction plate 500. It should be noted that the connecting plate 600 may be a rubber strip plate.

[0057] Please refer to Figures 6 and 7 The receiving opening 600a cooperates with the partition 200 to receive the check member 300 in the receiving opening 600a. Figures 8 and 9 The thickness of the check member 300 is smaller than that of the connecting plate 600, so when the adsorbent is placed on the partition 200 and covers the vent 100a, an adsorption gap 600c is formed above the adsorbent. The accommodating opening 600a can be adapted to the shape of the check member 300. For positioning the check member 300, please refer to Figures 6 and 7 Alternatively, when the check member 300 is located in the receiving opening 600a, the walls of the receiving opening 600a limit the opposite ends of the check member 300. A vacuum gap 600b exists between the walls of the receiving opening 600a and the other ends of the check member 300, increasing the airflow space and the suction force. Gas can flow from the suction opening 500a to the suction gap 600c, through the vacuum gap 600b and the gap 10a, to the vacuum opening 200a, and then to the vent 100a.

[0058] The present invention also provides a suction assembly comprising a suction cup structure 10 and a vacuum emitter or a vacuum pumping assembly. The vacuum emitter delivers compressed air through the vent 100a, or the vacuum pumping assembly draws a vacuum through the vent 100a. The specific structure of the suction cup structure 10 is similar to that of the aforementioned embodiments. Since this suction assembly utilizes all the technical solutions of all of the aforementioned embodiments, it possesses at least all the beneficial effects of the technical solutions of the aforementioned embodiments, and therefore will not be further detailed here.

Since this processing equipment adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.
