Independent block adsorption platform, control circuit and control method

Abstract

The invention provides an independent block adsorption platform, a control circuit and a control method. The independent block adsorption platform comprises an adsorption main platform, air hole plateand a sealing frame, the adsorption main platform is divided into M*N groove areas, each groove area is communicated with a vacuumizing device through a vent pipeline, a corresponding valve is connected between each groove area and the corresponding vent pipeline in series, and each valve can work independently; air holes are uniformly distributed in the air hole plate, the air hole plate is arranged above the adsorption main plate; the sealing frame is composed of M*N frames and is correspondingly arranged between the adsorption main plate and the air hole plate; and M and N are positive integers, and at least one of the M and the N is a positive integer greater than 1.

Description

technical field [0001] The disclosure belongs to the field of plate adsorption and cutting, and in particular relates to an independent block adsorption platform, a control circuit and a control method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Currently, the development of the liquid crystal display industry has prompted the rise of companies that produce liquid crystal display accessories. Light guide plate and diffuser plate are the most important production accessories and one of the core components of liquid crystal display. The light guide plate and diffuser plate are usually cut by a forming machine during mass production, but they are usually cut by a proofing machine during proofing and small batch test flow (this is because of the uncertain factors of the design before mass production, it may take To make design changes,...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing adsorption platform usually absorbs the entire surface. When the plate is smaller than the adsorption surface, the adsorption effect is greatly reduced because the plate does not cover the entire adsorption surface. The staff often use tape to stick the plate. It does not warp when cutting, which undoubtedly increases the workload and working consumables;

[0006] (2) The shape of the plate is not necessarily fixed (sometimes the plate needs to be processed twice, and the shape will not be the original regular rectangle). The traditional partition adsorption is actually not flexible, such as cutting " For H”-shaped plates, the traditional zoning cannot meet the requirements of the overall adsorption, and the zoning method adopted by the zoning adsorption is often realized by changing the distribution of the vacuum chamber partitions at the lower part of the adsorption platform. This method has poor sealing performance and cannot make the adsorption The force is evenly distributed, and the vacuum chamber is too large, which will also delay the adsorption, that is, when the adsorption switch is turned on, it cannot be adsorbed instantly, but can only be adsorbed after a period of time, wasting man-hours
