Description

Technical Field

[0001] The utility model relates to the technical field of suction cups, and more specifically, to a Bernoulli suction cup with high stability. Background Technique

[0002] A Bernoulli suction cup is a vacuum generating device manufactured based on the Bernoulli principle. It does not require an additional vacuum generator and only needs to be connected to compressed air. It can be divided into industrial applications and civilian applications. In industry, the "pick up" and "put down" during the handling and relocation processes are achieved by changing the vacuum degree of the suction cup, and automation and mechanization are realized in cooperation.

[0003] At present, the Bernoulli suction cup generally has a round and dish-shaped structure with a concave center. Negative pressure is generated inside the suction cup through high-speed air flow to achieve the purpose of sucking products.

When adsorbing some products with larger sizes, it is easy to cause instability during product adsorption. When adsorbing some products made of softer materials, the periphery of the product is prone to sagging, and it is difficult to keep the product flat during handling. Content of the Utility Model

The suction positions of the side suction assembly are evenly distributed at the bottom of the bottom plate 2 to increase the suction range of the product. The auxiliary suction assembly corresponds to the side suction assembly to increase the uniformity of the product suction.

[0038] In this embodiment, the air groove channel 5 is formed between the upper cover 1 and the bottom plate 2. After the upper cover 1 and the bottom plate 2 are assembled, a complete air groove channel 5 is formed. After the bottom plate 2 and the main core body 3 are assembled, a complete annular cavity 6 is formed. Compressed gas enters the air groove channel 5 through the air inlet nozzle 4, and then enters the annular cavity 6 through the plurality of air inlets 7, and is ejected from the periphery of the main core body 3 through the plurality of diffused air outlets 8 to generate negative pressure. When the product approaches the bottom of the bottom plate 2 and the main core body 3, suction is formed to realize the suction of the product. When the compressed gas is in the air groove channel 5, part of the compressed gas enters the side suction assembly, and the side suction assembly sucks the product around the bottom of the bottom plate 2. At the same time, the auxiliary suction assembly further improves the uniformity of the product suction.

[0039] Specifically, the air groove channel 5 is set in an irregular arc shape, and the cross-section of the air groove channel 5 is circular.

There is a certain gap between the circular core 95 and the bottom of the side core 92. The gas in the side core cavity 97 diffuses at the bottom of the side core 92 through the gap and is ejected through the exhaust groove 93, thereby generating negative pressure. When the product is close to the bottom plate 2 and the bottom of the main core 3, the product is sucked through the side suction port 94, improving the uniformity and suction range during product suction.

[0043] Specifically, the auxiliary suction assembly includes a plurality of air extraction holes 101, a plurality of side suction channels 102, and a plurality of auxiliary suction holes 103. The plurality of air extraction holes 101 are all formed in the bottom end of the bottom plate 2 and correspond to the plurality of side suction ports 94 respectively. The plurality of side suction channels 102 are all formed in the top end of the bottom plate 2 and correspond to the upper cover 1, and the plurality of side suction channels 102 communicate with the plurality of air extraction holes 101 respectively. The plurality of auxiliary suction holes 103 are all formed in the bottom plate 2 and correspond to the upper cover 1, and the plurality of auxiliary suction holes 103 communicate with the plurality of side suction channels 102 respectively.

[0044] In this embodiment, when the product is sucked close to the side suction port 94, a vacuum area is formed between the product and the side suction port 94. The air extraction hole 101 is located in the vacuum area, thereby extracting the air in the side suction channel 102 and the auxiliary suction hole 103 through the air extraction hole 101, making the auxiliary suction hole 103 generate a certain suction force and further improving the uniformity during product suction.

[0047] Specifically, four positioning ports 13 are formed on the bottom plate 2, and the four positioning ports 13 are evenly distributed around the central axis of the bottom plate 2.

[0048] In this embodiment, a certain space is left around the suction cup through the four positioning ports 13, which facilitates the positioning of the product and reduces the weight of the suction cup and the production materials.

[0049] Working principle: Compressed gas enters the gas groove channel 5 through the air inlet nozzle 4, then enters the annular cavity 6 through the plurality of air inlet ports 7, and is ejected from the periphery of the main core body 3 through the plurality of diffusion air outlet ports 8 to generate negative pressure.

When the product approaches the bottom plate 2 and the bottom of the main core body 3, the product is sucked through the side suction port 94. After the product is sucked, a vacuum area is formed between the product and the side suction port 94. The air in the side suction channel 102 and the auxiliary suction holes 103 is extracted through the air extraction hole 101, so that a certain suction force is generated in the auxiliary suction holes 103 to keep the suction of the product stable.
