Description

Technical Field

[0001] This utility model relates to the field of suction cup technology, specifically, to a material transfer suction cup device. Background Technology

[0002] Suction cups are widely used tools in automation, robotics, and production lines, primarily for gripping and moving objects of various shapes and sizes. Suction cups achieve adsorption and transport by generating negative pressure. A common working principle involves using an electric pump or pneumatic device to extract air from inside the suction cup, creating a vacuum that allows the suction cup to adhere tightly to the object's surface.

[0003] Suction cups are highly flexible and can adapt to materials of various shapes, especially when gripping smooth surfaces such as glass, metal, and plastic. Depending on the application, suction cups come in different types, including rubber, silicone, and polyurethane suction cups. Choosing the right suction cup can effectively improve the efficiency and safety of material handling.

[0004] When using ordinary suction cups to grasp materials with hardened or lumpy surfaces, uneven surfaces, or low filling rates, the material package may not adhere firmly to the suction cup, leading to package loss. Utility Model Content

[0005] The purpose of this invention is to provide a material transfer suction cup device to solve the problem that existing ordinary suction cups are prone to unreliable adsorption when transferring materials, resulting in the phenomenon of package loss.

[0006] This utility model is achieved through the following technical solution: a material transfer suction cup device, comprising: A disc body for providing a negative pressure chamber, the disc body including a housing; A connecting end, mounted on the disc body, is used to connect a suction pump and a robotic arm. The connecting end includes a connecting plate and a connecting pipe. A skirt, installed on the disc body, is used to seal the gap between the material package and the disc body. The skirt includes a side skirt, a first sealing edge, a second sealing edge, a pressure plate, and bolts. The side skirt is tapered, the second sealing edge is located at the end of the side skirt, and the first sealing edge is located in the middle of the side skirt. The pressure plate is located between the first and second sealing edges and is connected to the outer shell by bolts to realize the installation of the skirt on the disc body.

[0007] To better realize this utility model, the inner diameter of the second sealing edge is further smaller than the inner diameter of the first sealing edge.

[0008] To better realize this utility model, the thickness of the second sealing edge is further greater than the thickness of the first sealing edge.

[0009] To better realize this utility model, the connecting end further includes a dispersion tube, and both the connecting tube and the connecting plate are installed on the dispersion tube, and the dispersion tube is in communication with the outer shell.

[0010] To better realize this utility model, the disc body further includes a partition for limiting the material package, and the partition is provided with multiple ventilation holes.

[0011] To better realize this utility model, a reinforcing plate is further installed on the outer shell, the reinforcing plate is located between the two holes communicating between the dispersion tube and the outer shell, and the reinforcing plate is provided with vent holes.

[0012] To better realize this utility model, the outer shell is further provided with a reserved hole, and a pressure sensor is installed in the reserved hole.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects: This invention enhances the overall sealing effect of the suction cup by setting a double-layer sealing edge, while also securing the material package to prevent it from falling out. Practical application has shown that this skirt structure is highly adaptable to materials with hardened and clumped surfaces, uneven surfaces, low filling rates, and materials weighing between 25-70KG, effectively controlling the loss rate to around 0.3%, demonstrating excellent reliability.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1: This embodiment provides a material transfer device using a suction cup, specifically as follows: Figures 1-3 , Figure 7 , Figure 8 As shown, it includes: A disc body for providing a negative pressure chamber, the disc body including a housing 102; The connecting end is installed on the disc body and is used to connect the suction pump and the robotic arm. The connecting end includes a connecting plate 103 and a connecting pipe 104. The connecting plate 103 is connected to the external robotic arm, and the connecting pipe 104 is connected to the suction pump. A skirt, installed on the disc body, is used to seal the gap between the material package 20 and the disc body. The skirt includes a side skirt 101, a first sealing edge 106, a second sealing edge 107, a pressure plate 111, and bolts 112. The skirt is made of silicone material, and the first sealing edge 106, the second sealing edge 107, and the side skirt 101 are integrally formed. The side skirt 101 is tapered, the second sealing edge 107 is located at the end of the side skirt 101, and the first sealing edge 106 is located in the middle of the side skirt 101. The pressure plate 111 is located between the first sealing edge 106 and the second sealing edge 107, and is connected to the outer shell 102 by bolts 112 to realize the installation of the skirt on the disc body.

[0026] In use, the robotic arm moves the suction cup above the material package 20 and then lowers it, causing the side skirt 101 to press against the material package 20. At this time, the suction cup pump starts, and exhaust begins from the connecting pipe 104. Because the side skirt 101 is attached to the material surface, a negative pressure is formed inside the outer shell 102. The side skirt 101 then sucks the material package 20 in place. At the same time, because a sealing edge 106 is pressed against the surface of the material package 20, the initial sealing by the side skirt 101, combined with the negative pressure, helps the surface of the material package 20 to adhere tightly to the sealing edge 106, further increasing the internal and external pressure difference and making the material package 20 even more tightly sucked. When the suction cup is lifted upward by the robotic arm... Upon lifting, the material package 20 will fall under the influence of gravity, causing the side skirt 101 to separate from the surface of the material package 20. The sealing function of the side skirt 101 will fail. At this time, the first sealing edge 106 will take over the sealing function from the side skirt 101. Due to the negative pressure, part of the material package 20 will be sucked into the outer shell 102. That is, part of the material package 20 is higher than the second sealing edge 107. When the suction cup completely lifts the material package 20, the second sealing edge 107 not only provides a sealing function to maintain the negative pressure state, but also stably holds the material package 20 in place by the friction between the material package 20, which is higher than the second sealing edge 107, and the second sealing edge 107, preventing it from falling.

[0027] By setting a double-layer sealing edge 107, the overall sealing effect of the suction cup is further enhanced, and it can also lock the material package 20 in place, preventing the material package 20 from falling out. Practical application has shown that this skirt structure is highly adaptable to materials with hardened and clumped surfaces, uneven surfaces, low filling rates, and materials weighing between 25-70KG, effectively controlling the loss rate to approximately 0.3%, demonstrating excellent reliability.

[0028] Example 2: This embodiment further extends the above embodiment, specifically as follows: Figure 6As shown, the inner diameter of the second sealing edge 107 is smaller than the inner diameter of the first sealing edge 106. By setting the inner diameter of the first sealing edge 106 to be relatively small, the material package 20 is blocked not only by the first sealing edge 106 but also by the second sealing edge 107 when it is being sucked upwards. This double blocking effect prevents the material package 20 from being excessively sucked into the outer shell 102, which would cause inconvenience in subsequent unloading.

[0029] Furthermore, the thickness of the second sealing edge 107 is greater than the thickness of the first sealing edge 106. The greater thickness of the second sealing edge 107 results in stronger overall bending resistance, allowing it to secure the material package 20 within the outer shell 102, thus making the material package 20 more stable during transport and preventing it from being swapped out.

[0030] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0031] Example 3: This embodiment further extends the above embodiment, specifically as follows: Figure 1 , Figure 4 , Figure 5 As shown, the connecting end also includes a dispersion tube 105. The connecting tube 104 and the connecting plate 103 are both installed on the dispersion tube 105, and the dispersion tube 105 is connected to the outer shell 102.

[0032] Two suction ports are provided on the dispersion tube 105, which are located at both ends of the outer shell 102, to ensure that the suction force of the suction cup is balanced.

[0033] Furthermore, the disc body also includes a partition 108 for limiting the material package 20, and the partition 108 is provided with multiple vent holes. The partition 108 is to prevent the material package 20 from being excessively sucked into the outer shell 102, which would cause inconvenience in subsequent unloading; at the same time, it also prevents the material package 20 from directly blocking the two air intake ports of the dispersion tube 105.

[0034] Furthermore, a reinforcing plate 109 is installed on the outer shell 102. The reinforcing plate 109 is located between the two holes communicating between the dispersion tube 105 and the outer shell 102, and the reinforcing plate 109 is provided with vent holes. The vent holes on the reinforcing plate 109 ensure uniform airflow distribution at the partition 108; at the same time, the reinforcing plate 109 reinforces the wall of the outer shell 102, preventing the outer shell 102 from deforming under negative pressure for a long time.

[0035] Furthermore, the outer casing 102 is provided with a reserved hole 110, on which a pressure sensor is installed. If the material package 20 is switched during transfer, the negative pressure inside the outer casing 102 will disappear. This sensor will detect this and trigger an alarm, prompting staff to take remedial action.

[0036] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
