Description
Technical field:
The utility model relates to a kind of being used for the solder furnace of soldering on circuit board, refers to the solder furnace structure-improved of the angle when a kind of deflector that is provided with a changeable angle in the tin stove gushes tin with adjustment especially.
Background technology:
The combination of electronic component and printed circuit board (PCB) (PCB) is to adopt the mode of scolding tin at present.Yet traditional circuit board processing mode is that part pin is passed circuit board to copper-clad surface, and scolding tin is fixed the pin and the solder joint of part again.Afterwards, in order to increase the speed of production, utilized a kind of solder furnace of automation then, only need part is placed the position of setting on the circuit board, and this circuit board places on the bearing, this bearing hollow out goes out to utilize soldering to connect part, place track to advance again, after making it via the preheating zone, pass through tin stove top again, simultaneously, in the Yu Xilu the tin liquor of fusion be filled with and contact with bearing, stick to circuit board and be stained with, after waiting to return to normal temperature, promptly finish the joint of part.
Wherein,,,, it sticks on circuit board so that being able to complete being stained with so need to adjust height when gushing tin and being filled with because the size of circuit board and electronic building brick installing are deep mixed, however for reaching the purpose of adjusting height, the essential height of adjusting molten tin bath integral body, quite inconvenient.
Moreover, be attached to adhesive force on the circuit board for strengthening tin, need in tin liquor, to add the lead of certain content, but plumbous shadow for human body is to very huge, so the use of lead is forbidden in present RoHS instruction.For meeting the regulation of RoHS,, be attached to adhesive force on the circuit board to keep tin so need to change present processing procedure.
The utility model content:
The technical problem that the utility model solved is: at above-mentioned the deficiencies in the prior art, and the solder furnace structure-improved of the angle when providing a kind of deflector that is provided with a changeable angle in the tin stove to gush tin with adjustment.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of solder furnace structure-improved, it comprises a heater, a molten tin bath and a conveyer belt, this conveyer belt clamping component rows to be welded is through above-mentioned heater and molten tin bath, be characterized in: described molten tin bath upper end is provided with the deflector of liquid level of tin liquor when gushing tin in order to change, the two sides of this deflector are respectively protruded one, and wear the bearing block on the molten tin bath two side, make this axle to rotate with respect to bearing block.
So, by the deflector that molten tin bath upper end is provided with, the liquid level of the tin liquor when gushing tin in order to change, and each axle that protrudes of the two sides of deflector can rotate with respect to bearing block, can change the angle of inclination of deflector; The gear train that axle is provided with is able to adjust by this gear train easily the angle of deflector to drive this axle; In response to the regulation of RoHS and keep original adhesive force, and be provided with the scaling powder smear zone in front end, improve by this unleaded and cause adhere to hypodynamic problem; Because scaling powder also can produce escaping gas, so, before and after this district, be provided with air door, make outflow in order to stop the gas in this district, and be provided with an exhaust equipment in this district for avoiding this gas diffusion, this gas is discharged; Again, this air door comprises more than one air inlet and more than one air outlet, in this air inlet, be provided with the unit of bleeding, after the air suction, send by air outlet, and reach the circulation that intercepts this district and outside air, avoid this gas before discharging, to spill by import and export, avoid causing human body harm and avoid this gas to enter the preheating zone, and the too high catching fire of Yin Wendu.
For further understanding, and be that the technology personage of same industry can be implemented according to specification of the present utility model and embodiment, so it is as follows to disclose a preferred implementation, cooperates graphic, figure number, with its constitution content and the effect reached describes in detail as after:
