Problems solved by technology
[0002] In the current automatic production line, the automatic return design of the fixture in the line is very common. Since the fixture reciprocates on the production line, the fixture cannot be directly connected to the air pipe to achieve the vacuum adsorption effect of the fixture on the product.

Embodiment Construction
[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the specific embodiments and the accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concepts of the present invention.
[0027] like Figure 1-5 As shown, an independent negative pressure holding fixture proposed by the present invention includes a flat plate 3, a vacuum suction cup 2 is fixedly installed on the flat plate 3, and an inner vacuum chamber 6 is fixedly installed at the bottom of the flat plate 3;
[0028] One side of the inner vacuum chamber 6 is fixedly installed with a sealing plate 1 4 and a sealing plate 2 1;
[0029] The interior of the i...

The invention relates to the technical field of clamps, and discloses an independent negative pressure maintaining clamp which comprises a flat plate, a vacuum suction cup is fixedly installed on the flat plate, and an inner vacuum bin is fixedly installed at the bottom of the flat plate; a sealing plate I and a sealing plate II are fixedly mounted on one side of the inner vacuum bin; and a two-stage vacuum booster pump is arranged in the inner vacuum bin. The independent negative pressure maintaining clamp has the advantages that mechanical positioning is not needed, and the product damage risk is reduced; the fixture compatibility range is widened; the air path layout on the mechanism is optimized, the line is prevented from directly participating in mechanism movement, the service life of the line is prolonged, and the after-sale cost is reduced.
Description
technical field [0001] The invention relates to the field of clamps, in particular to an independent negative pressure holding clamp. Background technique [0002] In the current automated production line, the automatic reflow design of the fixture in the line has been very common. Since the fixture reciprocates on the production line, the fixture cannot simply be directly connected to the air pipe to achieve the vacuum adsorption effect of the fixture on the product. At the same time, the industry pays more and more attention to the protection of products in the production process. Preventing damage to products in the production process is always a key concern of the automation industry. Therefore, it is necessary to design a fixture that can maintain vacuum adsorption on the reflow line to reduce mechanical positioning. , reduce the risk of product damage. [0003] In order to solve the above problems, the present application proposes an independent negative pressure hold...
