Abstract
The utility model relates to the technical field of wave solder pot, in particular to a vector regulating valve for a wave solder pot. The vector regulating valve comprises a flow baffle which is arranged on one side of a spout frame body. A drop height groove is formed between the flow baffle and the spout frame body. The lower end of the drop height groove is provided with an opening. A flow regulating device for regulating the size of the opening is arranged at the opening. The opening is regulated by the flow regulating device so that a part of tin liquor is discharged from the opening, thus the drop height of the tin and the width of the tin wave crest are regulated. The vector regulating valve can satisfy the processing of various printed circuit boards. At the same time, when a narrow wave operation is carried out, the oxygenation of the tin can be reduced by regulating the drop height of the tin, thus the welding quality is improved.
Description
Technical field:
The utility model relates to crest solder furnace technical field, particularly a kind of crest solder furnace vector flow regulating valve.
Background technology:
In the printed circuit board (PCB) production process, there is the pin element to adopt plug-in part technology to carry out the plug-in unit assembling.At first element is inserted on the corresponding position of printed circuit board (PCB), by conveying mechanism printed circuit board (PCB) is delivered to crest welder then and welds at automatic or manual on the plug-in unit production line.Crest welder adopts internal or external spraying system, be sprayed on scaling powder on the printed circuit board (PCB) equably, carry out the thermophilic preheating through pre-heating system, weld through the tin stove again, after the quick cooling in cooling zone, tin becomes solid-state by settable liquid, and component pins and printed circuit board (PCB) are welded into one firmly.For satisfying the requirement of leadless process, guarantee high-quality welding quality, crest welder generally welds under inert gas environment, and the tin stove is by the titanium alloy manufacturing.
Existing crest solder furnace is provided with flow-stopping plate in crest spout support body one side, form the drop groove between flow-stopping plate and the spout support body, tin liquor enters the drop groove after spout flows out, go out to form crest from the drop concentrated flow again, since needed tin crest width difference during the welding of different printed circuit board (PCB)s, and this drop groove can not be regulated the width of tin crest, can not satisfy the printed circuit board (PCB) processing of multiple pattern, the amount of oxidation height of tin influences welding quality.
The utility model content:
The purpose of this utility model is to provide a kind of crest solder furnace vector flow regulating valve that can regulate tin crest width at the deficiencies in the prior art.
For achieving the above object, the utility model adopts following technical scheme:
Crest solder furnace vector flow regulating valve, it comprises the flow-stopping plate that is arranged on spout support body one side, forms the drop groove between flow-stopping plate and the spout support body, and described drop groove lower end is provided with opening, and opening part is provided with the accent stream device of regulating openings of sizes.
Described accent stream device comprises the adjusting-flow board of closing any opening fully, the rotating shaft and the regulating handle that with rotating shaft be connected fixedly connected with adjusting-flow board, and rotating shaft and spout support body are rotationally connected.
Described spout support body is fixed with the adjusting holder, regulates the stopper slot that offers restriction regulating handle rotational angle on the holder, and regulating handle is a L type bar, and an end of L type bar is connected with rotating shaft, and its other end passes stopper slot.
The outside of described flow-stopping plate upper end is fixed with downward-sloping wide ripple adjustable plate.
The utility model beneficial effect is: the utility model comprises the flow-stopping plate that is arranged on spout support body one side, form the drop groove between flow-stopping plate and the spout support body, drop groove lower end is provided with opening, opening part is provided with the accent stream device of regulating openings of sizes, the utility model makes the part tin liquor release from opening by the size of transferring the stream device to regulate opening, thereby regulate the drop of tin and the width of tin crest, can satisfy the printed circuit board (PCB) processing of multiple pattern, simultaneously when narrow ripple operation, can reduce the amount of oxidation of tin by the drop of regulating tin, improve welding quality; Secondly, transfer the stream device to comprise adjusting-flow board, the rotating shaft and the regulating handle that with rotating shaft be connected fixedly connected with adjusting-flow board, rotating shaft and spout support body are rotationally connected, and by regulating handle adjusting-flow board are rotated around the axis and change the size of opening, the size of opening can be regulated arbitrarily, and is simple to operate.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation at another visual angle of the utility model;
Fig. 3 is a cutaway view of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see Fig. 1～3, crest solder furnace vector flow regulating valve, it comprises the flow-stopping plate 2 that is arranged on spout support body 1 one sides, form drop groove 3 between flow-stopping plate 2 and the spout support body 1, described drop groove 3 lower ends are provided with opening 4, and opening 4 places are provided with the accent stream device of regulating opening 4 sizes.
Transfer the stream device to comprise the adjusting-flow board 5 of closing any opening 4 fully, the rotating shaft 6 and the regulating handle 7 that with rotating shaft 6 be connected fixedly connected with adjusting-flow board 5, rotating shaft 6 and spout support body 1 are rotationally connected.Spout support body 1 is fixed with regulates holder 8, regulates the stopper slot 9 that offers restriction regulating handle 7 rotational angles on the holder 8, and regulating handle 7 is a L type bar, and an end of L type bar is connected with rotating shaft 6, and its other end passes stopper slot 9.Just can make adjusting-flow board 56 rotate the size that changes opening 4 around the shaft by regulating handle 7, the size of opening can be regulated arbitrarily, and is simple to operate.
The outside of flow-stopping plate 2 upper ends is fixed with downward-sloping wide ripple adjustable plate 10, and wide ripple adjustable plate 10 can be regulated the width of tin crest.
The utility model makes the part tin liquor release from opening 4 by the size of transferring the stream device to regulate opening 4, thereby regulate the drop of tin and the width of tin crest, can satisfy the printed circuit board (PCB) processing of multiple pattern, simultaneously when narrow ripple operation, can reduce the amount of oxidation of tin by the drop of regulating tin, improve welding quality.
The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
