Abstract

The utility model relates to a circuit board suctioning and steering mechanism. An extracting and steering device is mainly formed by connecting a steering unit with a lifting unit and assembling an extracting unit under the lifting unit. The extracting unit can suck a circuit board by negative air pressure and can lift up the circuit board by the upward actuating of the lifting unit; and after the steering unit rotates the extracting unit for a certain angle horizontally, the lifting unit actuates downwards to be matched with the extracting unit so as to loosen and put down the circuit board. Different from the common extracting device which clamps the circuit board directly by a clamp and can cause damage to the surface of the circuit board due to pressure, the suctioning and steering mechanism conducts lifting-releasing or in-air rotating movements by the mode of sucking the circuit board and protects the surface of the circuit board from subjecting to any scrape, thus achieving the purpose of protecting the circuit board and further improving the defect-free rate of products.

Description

Circuit board is drawn steering mechanism

Technical field

The utility model relates to a kind of circuit board auxiliary processing device, and particularly a kind of circuit board is drawn steering mechanism.

Background technology

The progress of many industries has been brought up in the development of nanosecond science and technology, comprises that industries such as electronics, biological and material all thereby the progress of jump arranged.In electronic industry, be subjected to nanometer technology pool quilt, the various part set of datas all are able to microminiaturization.For example the compute chip size if in the past half less than size, the usefulness that can provide but surmounts more than one times; This makes that electronic product can be littler, lighter, thinner, and is but fast more, clever more, function is polynary more.

After the electronic product microminiaturization, follow and be the problem that precision improves in the manufacture process.Because each part set of data all dwindles, no matter be assembling or transport and all need more careful protection, in order to avoid part is impaired and influence the rate of pass in processing procedure.

Electronic product inside generally all is that the various parts of configuration form on circuit board, and circuit board is the lift-launch substrate of part, and its importance is ineffable.Circuit board is composite bed compacting to be cut again form, and there are irregular burr at its plate body edge, does not only cut hand and easily hurts sb.'s feelings in the edge if do not handle burr, more can cause composite bed to peel off easily, influences product yield and durability.So it is to make board edge smooth these burr polishings that one step arranged in the processing procedure of circuit board, one comes the edge can not cut hand, and two come composite bed also can not peel off easily.

Because circuit board mostly is rectangle, four limits,, all needs to be applied to and carry and turn to no matter be to carry out edging or cut.Turn in the operation in known conveying, circuit board is directly to be held by anchor clamps to get, circuit board surface is unavoidable thereby cause a little crushing or fray, therefore more inexact in the past circuit board can not influence the functional operation of its finished product, but the electronic product of a new generation is impaired with regard to not allowing circuit board surface to have now.Because the circuit board that microminiaturized electronic product is used, though the little circuit of volume is more complicated; The circuit of its close and numerous issue often as long as a trail scratch just may have and open circuit or short circuit, makes that finished product can't normal operation.

The designer satisfies and specially creates into the utility model to grind because known anchor clamps are held the sense circuit plate and caused damage easily, and the phase can rely on proposition of the present utility model, and improving existing shortcoming, the phase can be kept perfectly circuit board and not impaired in processing procedure.
