Abstract
The utility model relates to the technical field of wave solder pot, in particular to a gradual type flow equalizing board for a wave solder pot. The flow equalizing board comprises a base plate. A plurality of n-shaped baffles are arranged parallelly on the base plate along the flow direction of tin liquor. Each baffle is provided with a tin inlet which is extended to the bottom of the baffle. The area of the tin inlet on each baffle is gradually decreased along the flow direction of the tin liquor. The tin inlet of the baffle is combined to form a gradually narrowing straight passage. A tin outlet is formed on the upper side between two baffles. When the tin liquor passes through each tin inlet of one baffle, the impulsive force of the tin liquor is dispersed and cushioned because the next tin inlet is narrowed. Furthermore, the surplus tin liquor is forced to flow out from the tin outlet between two baffles. Therefore, after passing the straight passage, the tin liquor forms a directed and even tin flow which is discharged from the tin outlet. The flow equalizing board has the advantages that the flow equalizing board is simple in structure, the flowing space of the tin liquor is large, the blockage is uneasy to form, the flow equalization effect is good, the wave crest is stable, and the welding quality is good.
Description
Technical field:
The utility model relates to crest solder furnace technical field, the gradual homogenizing plate of particularly a kind of crest solder furnace.
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.
Tin liquor in the crest solder furnace is after the pressurization of tin pump, flow direction and flow are all unstable, therefore be provided with the homogenizing plate of balanced tin liquor at the inner place of high crest spout, existing homogenizing plate comprises, following two blocks of parallel plates, upper plate is provided with stannum export, on, all be provided with baffle plate on the lower plate side by side, on, baffle plate on the lower plate staggers mutually, the height of baffle plate increases successively along the tin liquor flow direction, baffle plate will be gone up, space between the lower plate is divided into the wave shaped form that narrows down gradually and advances the tin passage, tin stream advances in the tin passage to pass through in the wave shaped form that narrows down gradually, and the tin passage that advances that narrows down gradually forces tin stream to flow out toward the stannum export of upper plate gradually, thereby reaches the current-sharing effect; It is narrower that but the formed wave shaped form that narrows down gradually of this homogenizing plate is advanced the tin channel space, results in blockage easily, and the passage complications, and the current-sharing effect is bad, and crest is not steady, influences welding quality.
The utility model content:
The purpose of this utility model is to provide a kind of to the effective gradual homogenizing plate of crest solder furnace of tin liquor current-sharing at the deficiencies in the prior art.
For achieving the above object, the utility model adopts following technical scheme:
The gradual homogenizing plate of crest solder furnace, it includes base plate, base plate upper edge tin liquor flow direction has been arranged side by side polylith " n " type baffle plate, offers the tin inlet that extends to its bottom on the baffle plate, and the tin inlet area on every baffle plate successively decreases successively along the tin liquor flow direction.
Tin inlet area on the described every baffle plate is proportional successively to be reduced.
Offer bar hole on the described base plate.
The utility model beneficial effect is: the utility model includes base plate, base plate upper edge tin liquor flow direction has been arranged side by side polylith " n " type baffle plate, offer the tin inlet that extends to its bottom on the baffle plate, tin inlet area on every baffle plate successively decreases successively along the tin liquor flow direction, the tin inlet of baffle plate is combined to form the straight type passage that narrows down gradually, top between per two baffle plates forms stannum export, when tin liquor whenever flows through the tin inlet of a baffle plate, can diminish the impulse force dispersion buffering of tin liquor because of next tin inlet, and unnecessary tin liquor is forced to flow out from the stannum export between two baffle plates, tin liquor is after flowing through straight type passage like this, just form one orientation, tin stream flows out from stannum export uniformly, homogenizing plate of the present utility model is simple in structure, the tin liquor flowing space is big, is not easy to result in blockage, and current-sharing is effective, crest is steady, and welding quality is good.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 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. 1～2, the gradual homogenizing plate of crest solder furnace, it includes base plate 1, base plate 1 upper edge tin liquor flow direction has been arranged side by side polylith " n " type baffle plate 2, offer the tin inlet 3 that extends to its bottom on the baffle plate 2, tin inlet 3 areas on every baffle plate 2 successively decrease successively along the tin liquor flow direction, and the top between per two baffle plates 2 forms stannum export.Proportional successively the reducing of tin inlet 3 areas on every baffle plate 2, in the present embodiment, tin inlet 3 is a rectangle, and its long and wide all proportional successively reducing can be adjusted the tin stream flow that up flows out stannum export by tin inlet 3 area ratios on the control baffle plate 2 and the distance between the baffle plate 2.Base plate 1 is fixed on the tin stove by screw, offers bar hole 4 on the base plate 1, and screw passes bar hole 4 and is spirally connected with the tin stove, can regulate the position of homogenizing plate in the tin stove by bar hole 4.
The tin inlet 3 of baffle plate 2 is combined to form the straight type passage that narrows down gradually, when tin liquor whenever flows through the tin inlet 3 of a baffle plate 2, can diminish the impulse force dispersion buffering of tin liquor because of next tin inlet 3, and unnecessary tin liquor is forced to flow out from the stannum export between two baffle plates 2, tin liquor is after flowing through straight type passage like this, just form one orientation, uniformly tin stream flows out from stannum export, homogenizing plate of the present utility model is simple in structure, the tin liquor flowing space is big, be not easy to result in blockage, current-sharing is effective, and crest is steady, and welding quality is good.
The above only is a better 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.
