Vacuum adsorption platform

Abstract

The invention discloses a vacuum adsorption platform which comprises a base, a table piece and multiple regulation pieces; the table piece is provided with a core body; a plurality of through-hole-shaped cells are formed in the core body in a penetrating manner; a plurality of first connecting channels are arranged on the walls of the cells respectively so as to enable adjacent cells to be communicated with each other; a face plate is attached to one side, away from the base, of the core body and closes orifices at one ends of the cells; and a back plate is attached to one side, facing the base, of the core body and closes orifices at the other ends of the cells; a plurality of air holes are formed in the face plate respectively and are communicated with the cells respectively; and the regulation pieces are arranged between the table piece and the base so as to change distances between different portions of the table piece and the base. For the vacuum adsorption platform provided by the invention, a plurality of cells of the honeycomb core body are provided with connecting channels for enabling the cells to be communicated with one another in a radial direction, so that air can flow in each cell, and the phenomenon that when local air flow paths are blocked, the possibility that outward flowing of the air in local cells is influenced is avoided.

Description

technical field [0001] The invention relates to a working platform, in particular to a vacuum adsorption platform. Background technique [0002] see figure 1 As shown, the existing vacuum adsorption platform 1 is to sandwich the honeycomb core 2 between the honeycomb panel 3 and the honeycomb backboard 4, and make the air holes 3a, 4a on the honeycomb panel 3 and the honeycomb backboard 4 correspond to each other one by one, so as to Each cell hole 2a of the honeycomb core 2 constitutes an independent chamber, and then connects multiple independent chambers through the space provided by the partition frame 5, so that the suction can be concentrated, whereby the existing vacuum adsorption platform 1 can The air in the partition frame 5 space is extracted through the external air extraction device, and then the air in each independent chamber is extracted synchronously, so as to form a negative pressure area on the honeycomb panel 3 to absorb the processed The working object...

AI Technical Summary

Problems solved by technology

[0003] In the above-mentioned known technology, it is necessary to ensure that the air holes 3a, 4a correspond to the two ends of the same cell 2a during assembly, which will only increase the inconvenience in workmanship. At the same time, if the air holes 4a on the honeycomb back plate 4 are accidentally blocked during assembly , will cause the air in the corresponding independent chamber to be unable to be extracted, which will affect the adsorption effect of the existing vacuum adsorption platform
