Abstract

The utility model discloses a plugboard rack, which belongs to the field of circuit board positioning devices and aims to solve the problem that during processing of circuit boards, an existing plugboard rack used for drying the circuit boards is unventilated and hard to dry edges of the circuit boards. The plugboard rack comprises a first plugboard rack body and a second plugboard rack body which are connected through horizontal adjusting rods, each of the first plugboard rack body and the second plugboard rack body comprises a bottom plate fastening slot and a plurality of vertically-arranged positioning grooves fixed on the bottom plate fastening slot, and a ventilation structure is arranged at the bottom of the positioning grooves. Holes are drilled at the bottom of the positioning grooves, so that the plugboard rack has excellent ventilation performance and avoids abandonment of defective products caused by the fact that the edges of the circuit boards are not dried.

Description

A kind of flashboard rack

Technical field

The utility model relates to wiring board registration device field, is specially a kind of flashboard rack.

Background technology

In the wiring board procedure for processing, the roller coating of internal layer wet film, silk-screen resistance weldering, silk-screen character, vertical melanism all need be used the flashboard rack drying-plate.Flashboard rack generally adopts the both sides of the mode adapter plate of groove location at present.A kind of accurate printed circuit board thin plate flashboard rack device is disclosed like Chinese patent CN201020233157.6; This flashboard rack mainly includes flashboard rack main body, horizontal anomalous movement adjust bar; The horizontal anomalous movement adjust bar is located on the flashboard rack main body, and the flashboard rack main body is provided with careen grid.Yet because the stuffy edges of boards that cause easily of detent are difficult to oven dry, and edges of boards are not dried and are caused product defects to scrap in process of production easily.

Can only take at present to extend the drying-plate time with increase the cleaning of exposure process mediella, deal with the edges of boards baking and do not do problem.

Summary of the invention

Use the flashboard rack drying-plate in the wiring board course of processing in order to overcome; Stuffy; The problem that edges of boards are difficult to dry is avoided causing out short circuit to scrap on the egative film because the printing ink exposure that edges of boards are not dried the time is bonded at, and the utility model aims to provide a kind of flashboard rack; The detent of this flashboard rack is the ventilated type detent, can guarantee that edges of boards fully dry.

To achieve these goals, the technical scheme that the utility model adopted is:

A kind of flashboard rack; Comprise the first flashboard rack main body and the second flashboard rack main body; This first flashboard rack main body links to each other through levelling lever with the second flashboard rack main body; The said first flashboard rack main body and the second flashboard rack main body include the base plate draw-in groove and are fixed on the base plate draw-in groove many vertical detents of arranging, its constructional feature is, are provided with aeration structure at the bottom land of said detent.

As a kind of preferred version, said aeration structure is out the vent window at the detent bottom land.Further, said vent window is a plurality of poroid or strips, through vent window, can guarantee that edges of boards thoroughly dry.

As another kind of preferred version, said aeration structure is inboard ventilation slot or the fin of bottom land that is arranged on detent, further; This ventilation slot is a groove; Structure can keep edges of boards and detent bottom land gapped, during baking thus; Air forms convection current in ventilation slot, guarantee the edges of boards oven dry thoroughly.

Said detent is preferably U type groove.

By said structure, flashboard rack is divided into the first flashboard rack main body and the second flashboard rack main body, and the first flashboard rack main body and the second flashboard rack main body mainly are made up of detent and bottom draw-in groove.The present invention makes the ventilated type detent through in the perforate of detent bottom land or ventilation slot is set or fin is set, and guarantees that edges of boards keep ventilation state, thereby when baking, can fully dry edges of boards.

Compared with prior art; The beneficial effect of the utility model is: the present invention is in the bottom land punching of detent; Make it have good air permeability; Solved the stuffy problem that causes edges of boards to be difficult to dry up hill and dale, avoided because the product defects that the edges of boards problem of not drying causes is in process of production scrapped.

Below in conjunction with accompanying drawing and embodiment the utility model is done further to set forth.

The specific embodiment

Embodiment 1

A kind of flashboard rack, as shown in figures 1 and 3, comprise the first flashboard rack main body 1 and the second flashboard rack main body 2; This first flashboard rack main body 1 links to each other through levelling lever 3 with the second flashboard rack main body 2; The said first flashboard rack main body 1 and the second flashboard rack main body 2 include many U type detents 4 and base plate draw-in groove 5 of vertical layout, and be as shown in Figure 2, has vent window 6 at the bottom land of said detent 4; The bottom land part hollow out of said detent 4 strengthens draft power.

Embodiment 2

A kind of flashboard rack, like Fig. 1 and shown in Figure 4, structure is similar with embodiment 1; Its difference is, and is as shown in Figure 5, has ventilation slot 7 in the bottom land inboard of said detent 4; This ventilation slot 7 is a groove, because the existence of ventilation slot 7, air forms convection current during baking; Have the gap between the bottom land of edges of boards and detent 4, can guarantee that edges of boards are fully dry.

Embodiment 3

A kind of flashboard rack, like Fig. 1 and shown in Figure 4, structure is similar with embodiment 1; Its difference is, and is as shown in Figure 6, is provided with fin 8 in the bottom land inboard of said detent 4; Because the existence of fin 8 has the gap between the bottom land of edges of boards and detent 4, can guarantee that edges of boards are fully dry.
