Put, coordinate Multi-point temperature-controlled, be allowed to can arrange welding temperature curve flexibly, it is ensured that welding process requirement, can effectively solve technology
Problem in background.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of Lead Free Reflow Soldering device, including
Control station and reflow welding platform, be provided with some thermal convection current fans, some infrared radiation panels and cooling fan, institute in described reflow welding platform
State and below reflow welding platform, be sequentially provided with entrance, the first preheating table, the second preheating table, the 3rd preheating table, the 4th preheating from left to right
Plate, welder, Slow cooling district, natural cooling district and pressure cooling zone and outlet.
Further, described first preheating table, the second preheating table, the 3rd preheating table, the 4th preheating table use aluminium sheet material
Further, equally spaced on described drug volatilization plate it is provided with drug volatilization hole.
The beneficial effects of the utility model:
This utility model uses infrared radiation panel heating, increases thermal convection current fan, improves the heat-insulation layer of Re-current welder drying tunnel
Design, improves the uniformity of temperature, reasonable arrangement irradiator position, coordinates Multi-point temperature-controlled, be allowed to can arrange welding temperature flexibly
Curve, it is ensured that welding process requirement, payes attention to the design of cooling zone, makes the SMB after welding have a cooling procedure more slowly, right
Reduce internal stress, to prevent from ftractureing be favourable.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram；
Being numbered in figure: 1-control station, 2-reflow welding platform, 3-thermal convection current fan, 4-infrared radiation panel, 5-cools down fan,
6-entrance, 7-the first preheating table, 8-the second preheating table, 9-the 3rd preheating table, 10-the 4th preheating table；11-welder；12-delays

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
As it is shown in figure 1, a kind of Lead Free Reflow Soldering device, including control station 1 and reflow welding platform 2, set in described reflow welding platform 2
There are some thermal convection current fans 3, some infrared radiation panels 4 and cooling fan 5, set the most successively below described reflow welding platform 2
There are entrance the 6, first preheating table the 7, second preheating table the 8, the 3rd preheating table the 9, the 4th preheating table 10, welder 11, Slow cooling
District 12, natural cooling district 13 and pressure cooling zone 14 and outlet 15.
On above-described embodiment preferably, described first preheating table the 7, second preheating table the 8, the 3rd preheating table the 9, the 4th preheating table
10 use aluminium sheet material.
Concrete, this utility model infrared radiation panel temperature distribution uniform, for larger area and more complicated workpiece
Can process very well.Its back also has heat-insulation layer, can reduce thermal losses, beneficially drying tunnel heat-insulation layer design.At each temperature control
District arranges hot air convection device, improves temperature homogeneity, and the gas of volatilization in welding is derived.
This utility model segments preheating zone, weld zone and cooling zone further according to welding process requirement, many to realize
Point temperature control.In preheating zone, help weldering effect for preventing the scaling powder in excessive thermal shock, beneficially soldering paste from playing, prevent
Pore and bead splash, and will just be easy to control with slower speed heating, the subregion that at least be divided into more than 3.For avoiding
Infringement to element, weld zone is the shortest.Form high temperature peak district in this district, be rapidly completed welding.So weld zone is not
Subdivide.Cooling zone can be divided into 3 sub regions: Slow cooling district, natural cooling district and force cooling zone.Divide according to region
Dispose board-like irradiator, determine irradiator number by drying tunnel size, by welding temperature curve determine the power of irradiator.In advance
The irradiator of hot-zone is placed in below transmission network；The irradiator of weld zone all disposes at the upper and lower of transmission network；Cooling zone is uneasy
Put irradiator, simply cooling zone structure design with scheme) compared with Duo Liaoyige Slow cooling district.It addition, on drying tunnel entrance
It is big that Fang Jiayi group radiant panel is because porch heat radiation, and the initial rate that SMB temperature from ambient begins to ramp up may select.So,
Just can solve the puzzlement when room temperature is relatively low.
Based on above-mentioned, this utility model uses infrared radiation panel heating, increases thermal convection current fan, improves Re-current welder drying tunnel
Heat-insulation layer design, improve temperature uniformity, reasonable arrangement irradiator position, coordinate Multi-point temperature-controlled, be allowed to arrange flexibly
Welding temperature curve, it is ensured that welding process requirement, pay attention to cooling zone design, make the SMB after welding have one the coldest
But process, to reducing internal stress, to prevent from ftractureing be favourable.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
