Technical field

The utility model is specifically related to a kind of processing unit that immerses that ultra-thin plate is carried out the chemical process processing.

Background technology

The plate processing procedure that printed circuit board (PCB) or other are laid with circuit must pass through multiple tracks chemical treatment program.Therefore early stage plate all adopts horizontal conveyer to carry in the chemical treatment processing procedure because thickness is bigger.Along with the continuous evolution of industrial technology and the requirement of electronic product slimming and light and handyization; the thickness of some printed circuit board (PCB)s or relevant plate is thin (about 25 μ m～150 μ m) more and more; to such an extent as to plate has become ultra-thin soft board; therefore, if adopt traditional horizontal conveyer to carry soft board, sheet material will cause the plate distortion because of flexibility and the action of gravity of self; cause clamp at course of conveying easily; plate is damage therefore, even causes shutdown, and the product fraction defective is quite high.

The utility model content

The purpose of this utility model is to propose a kind of sheet immersing processing unit; thereby when solving ultra-thin soft board and adopting the horizontal feed mode to carry out the chemical treatment processing procedure, cause clamp at course of conveying easily, the plate damage; even cause shutdown, the problem that the product fraction defective is high.

For achieving the above object, the utility model has adopted following technical scheme:

A kind of sheet immersing processing unit comprises:

One immersion tank, having inner width is the district of immersing of 1～2cm, the both sides, top of this immersion tank are provided with the swash plate of symmetry and constitute horn mouth;

At least one pair of waterfall stream feeding unit is located at swash plate top, bell-mouthed relative both sides, provides waterfall flow liquid body to flow downstream into described immersion tank;

At least one pair of feeding unit that shoves is located at both sides relatively, this immersion tank top, provides the liquid that shoves to flow into immersion tank;

One mechanism of releasing is with described immersion tank winding, in order to the liquid in the immersion tank is discharged.

A kind of preferable selection, the angle between the horn mouth both sides swash plate of the immersion tank top of the utility model is 40 °～60 °, can make thin plate obtain the best effect that enters immersion tank in this angular range.

A kind of preferable selection, the utility model can be in the immersion tank setting mechanism of releasing, thin plate is carried out chemical treatment and when entering thin plate in the immersion tank, start this mechanism of releasing, allow the interior liquid of immersion tank discharge immersion tank, allow immersion tank produce down suitable suction, cooperate the drive of aforesaid waterfall flow liquid body and the liquid that shoves, enter immersion tank with further help sheet.

A kind of preferable selection, the utility model can utilize two groups of pipelines to be communicated to the riser top, relative both sides and bell-mouthed relative both sides swash plate top of immersion tank respectively, drive liquid by pumping and flow down formation waterfall flow liquid body from the horn mouth top, and form the liquid that shoves from the outflow of immersion tank both sides riser top.

The utility model utilizes the lifting plate fetching machine to cooperate clamper with thin plate clamping and conveying, and thin plate is vertically entered in the immersion tank of splendid attire chemical liquid with upright state, and maintains in the immersion tank and moved by horizontal feed; Thin plate is when vertically entering immersion tank, provide liquid to flow at the inner surface of immersion tank, utilize liquid to contact with internal face avoiding as the spacer medium of thin plate and immersion tank internal face, and utilize the both sides flowing liquid to provide suitable supporting role to thin plate, allow thin plate be entered in the immersion tank smoothly, avoid ultra-thin soft board when touching liquid level,, and then significantly promote the product yield because of the reaction force deflection of liquid resistance causes clamp.
