Problems solved by technology
However, the existence of double-sided tape will also cause damage to the surface of the object, and the guarantee of air tightness basically depends on the deformation of the double-sided tape. For objects with a large degree of roughness, the conformal ability of double-sided tape is difficult to ensure air tightness
[0007] Chinese patents similar to the above include 201710081547.2 and 201510349314.7. They can only guarantee airtightness to a certain extent, and their versatility is low. They have good adsorption and clamping effects for some specific parts, but they cannot meet the requirements of multi-variety, small Requirements for mass production lines

Embodiment 1
[0039] Below in conjunction with the accompanying drawings, the working process of vacuum suction cup adsorption and clamping of the present invention will be further elaborated:
[0040] The first hose 1 is connected to the first positive pressure source for air supply, and the second hose 9 is connected to the second positive pressure source for air supply. The air pressures of the two positive pressure sources are inconsistent, and at the same time, the air path of the first hose 1 is paralleled for vacuum generation. The air source of the vacuum generator adopts the third positive pressure source to supply air, and the vacuum generator is also connected in parallel in the air circuit of the second hose 9, and the vacuum generator in this air circuit adopts the fourth positive pressure source to supply air.
[0041] First, move the vacuum chuck over the workpiece, and then use a second positive pressure source to supply air to the inside of the film 10 during the descent, so...

The invention discloses a vacuum cup based on particulate matter moulding. The vacuum cup comprises a thin film attached to the surface of an object. The thin film is filled with a particle material,an inner connecting plate is embedded to the neck portion of the thin film, and two blind holes are formed in the upper portion of the inner connecting plate. An upper end cover achieves locating andconnecting through the two blind holes of the inner connecting plate. The lower surface of the upper end cover is connected with a fixed cover for preventing excessive deformation of the thin film, two limiting bolts are embedded to the upper surface of the upper end cover, and the limiting bolts are fixed through connection between the locating plate and the upper end cover. A hose passes throughthe center of the locating plate, the bottom of the hose is connected with the top plate, and the top plate is attached to the bottom of the thin film. The hose ascends and descends through a hose fixing part, meanwhile, the top plate is driven to form changing of the concave depth of the bottom of the thin film, and a suction cup shape with the edge being annular is formed due to the fact that the bottom of the thin film is concave, and the aims of attachment and moulding can be achieved well.
Description
technical field [0001] The invention relates to the field of pneumatic transmission, in particular to a vacuum suction cup based on particle shaping. Background technique [0002] In the pneumatic transmission system, the vacuum suction cup is a practical and effective adsorption and clamping tool. For most objects with a smooth and flat outer surface, the vacuum suction cup can achieve a good adsorption and clamping effect. However, with the development of automation in production lines in various industries, the complexity and diversity of the clamped workpieces have continuously increased the conformity requirements of the suction cup. Due to the edge shape and material of traditional vacuum chucks, it is difficult to ensure airtightness when absorbing and clamping objects with rough surfaces, and poor airtightness can easily lead to clamping failure. At the same time, the types of objects that can be adsorbed and clamped are single, which cannot meet the needs of modern...
