Description

Furnace tool is crossed in a kind of Reflow Soldering

Technical field

This utility model is related to mechanical tool field, and furnace tool is crossed in more particularly to a kind of Reflow Soldering.

Background technology

At present during LED lamp tube attachment, it is directed to use with crossing furnace tool, the fixation that existing tool is adopted to Reflow Soldering Mode is spring pull fastening type, but this fixed form often has spring pulling buckle dynamics inequality during tool attachment Even problem, easily causes pcb board and departs from fixed position during use, the temperature fall of pcb board becomes big before and after Reflow Soldering, takes off The pcb board for falling is susceptible to deformation；And the service life of spring pulling buckle is short, the service life for causing tool shortens, and causes system Cause this raising.

And, current Reflow Soldering is crossed on furnace tool and only offers louvre, but tray body thickness itself is big, is dissipated The thermal Finite that hot hole is distributed, and louvre limited by itself size and depth, easily causes heat aggregation and not volatile.

Utility model content

This utility model crosses furnace tool there is provided a kind of Reflow Soldering, solve existing tool easily cause pcb board come off and The short problem of service life.

For achieving the above object, technical solutions of the utility model are：

Furnace tool, including pallet are crossed in a kind of Reflow Soldering, the tray upper surface be provided with multiple PCB deep gouges (PCB deep gouges Quantity is flexibly arranged according to the size of pallet and the size of pcb board, can be 1,2,3 ...), described in each Fixing device is equipped with PCB deep gouges, the fixing device is upper on two opposite side of the PCB deep gouges including being installed on Fixture and lower fixture, the lower fixture includes lid, shell fragment and pulling buckle, and the lid is fixed on the pallet, The shell fragment and the pulling buckle are installed between the lid and the tray upper surface；Stroke is offered in the middle of the lid Groove, the stroke groove both sides offer shell fragment mounting groove；The pulling buckle includes drive division and from the drive division side That the heart stretches out and perpendicular to the fixed part of the drive division, the fixed part loads in the stroke groove and can be in the row Move back and forth in journey groove, the fixed part bottom is fixed with pin in the one side away from the stroke groove；The shell fragment point is listed in The both sides of the fixed part, it includes the fixed arm being connected with each other and elastic arm, and the fixed arm is installed in the shell fragment and installs In groove, the elastic arm contact is on the drive division.

Further, the shell fragment is formed in one structure.

Further, on the stroke groove and it is equipped with radiating elongated hole on the drive division.

Further, screwed hole is offered on the lid.

Further, the pallet is provided with louvre, and the louvre is distributed in multiple PCB deep gouges surroundings.

Further, the louvre periphery is further opened with radiating groove.

Further, fixed part is provided with fixing pin and fixture louvre.

From above-mentioned to description of the present utility model, compared to the prior art, this utility model has the advantage that：

First, this utility model using cooperatively by upper fixing element and lower fixture, pcb board is fixed on pallet, its In lower fixture using the pulling buckle of spring-piece type, not only pcb board can well be fixed, and dynamics is uniform, is unlikely to deform, Long service life, extends the service life of tool, reduces production cost.

2nd, this utility model offers louvre on the surrounding of PCB deep gouges, upper fixing element and lower fixture, makes Pcb board in reflow process and after Reflow Soldering is finished can Homogeneouslly-radiating, prevent pcb board due to radiating it is uneven caused by shape Become and the problems such as LED dead lamp, increase the yields of product.

3rd, radiating groove has been added in the louvre periphery of PCB deep gouge surroundings in this utility model, has on the one hand reduced pallet Thickness, accelerate radiating；On the other hand, convection current is formed between louvre and radiating groove, accelerates the volatilization of heat.
