Abstract
The utility model relates to a kind of soldering iron bit, comprise solder horn body, the head side of the being rod-like structure of described solder horn body, the tip of head is with square sloped surface, square sloped surface is coated with suction tin coating, with α angle between the perpendicular of square sloped surface and head, the scope of α angle is 30 °-60 °.Structure of the present utility model is simple, reasonable in design; By the solder horn head design side of one-tenth rod-like structure, and square sloped surface is set, allow part preferentially can touch tin liquor, the perspective plane of tin liquor is increased simultaneously, part larger for two position deviations touches by the large contact surface of solder horn simultaneously simultaneously, utilize the surface tension of tin liquor ensure each part can by while tin liquor parcel firm welding, reduce dry joint or sealing-off probability.
Description
Technical field
The utility model relates to the processing technique field of PCB, particularly a kind of solder horn for PCB welding.
Background technology
At present, the solder horn overwhelming majority that three-dimensional welding robot uses is all the solder horn continuing to use traditional-handwork welding electric iron.Traditional solder horn is relatively effective for the pin welding on wiring board, but to the direction of welding and positioning requirements higher.General is all PCB be fixed on horizontal plane tool, have a fixing position and between two weld parts positions error requirements very little, pad also must be could welding of horizontal plane.As run into the bar product needed welding of some horizontal positioned, pad be upright state, the position simultaneously between two weldments also with certain randomness, i.e. the solder joint of error between 0.5 millimeter to 2 millimeters, and traditional solder horn is difficult to be competent at.The main cause that traditional solder horn lost efficacy is that the position of tining on solder horn cannot accurately be located because of the inconsistency of every solder horn.Scolding tin on solder horn is not the head front end hanging over solder horn, but above its head front end point, during welding, solder horn tip contacts has arrived part often, but tin liquor is also above solder horn tip, tin liquor is caused not reach the position of part needs welding; Even if tin liquor touches welding position, because tin liquor is in a liquid state half drops, horizontal projected area is very little, be difficult to two weldments all be touched simultaneously, can only take into account one, only having on a part after causing welding has scolding tin, thus cannot weld between two parts, finally weld unsuccessfully, form dry joint or sealing-off.Therefore need the angle adjusting flatiron in time, but needed again a large amount of debugging efforts when solder horn loses efficacy and more renews solder horn, quite waste time and energy, and cause the waste of a large amount of debugging scrap.
Utility model content
The above-mentioned shortcoming that the applicant exists when the three-dimensional weld parts face that weld horizontal is placed for traditional soldering iron head, carry out studying and improving, a kind of soldering iron bit is provided, improve effective welding of three-dimensional part and ensure success rate, particularly on automatic welding equipment, improve welding efficiency, reduce scrap and produce.
In order to solve the problem, the utility model adopts following scheme:
A kind of soldering iron bit, comprises solder horn body, the head side of the being rod-like structure of described solder horn body, the tip of head is with square sloped surface, square sloped surface is coated with suction tin coating, with α angle between the perpendicular of square sloped surface and head, the scope of α angle is 30 °-60 °.
Further improvement as technique scheme:
Described α angle is 30 °.
Technique effect of the present utility model is:
Structure of the present utility model is simple, reasonable in design; By the solder horn head design side of one-tenth rod-like structure, and square sloped surface is set, allow part preferentially can touch tin liquor, the perspective plane of tin liquor is increased simultaneously, part larger for two position deviations touches by the large contact surface of solder horn simultaneously simultaneously, utilize the surface tension of tin liquor ensure each part can by while tin liquor parcel firm welding, reduce dry joint or sealing-off probability.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1, the soldering iron bit of the present embodiment, comprise solder horn body, head 10 side of the being rod-like structure of solder horn body 1, the tip of head 10, with square sloped surface 2, square sloped surface 2 is coated with and inhales tin coating 3, with α angle between the perpendicular of square sloped surface 2 and head 10, the scope of α angle is 30 °-60 °, and α angle is 30 °.
The present invention has made the tip of common solder horn or water chestnut face into square sloped surface 2, and apply to inhale tin coating 3 in square sloped surface 2, and other position is all that plating solder resist material is as nickel, it can ensure that scolding tin dissolves the rear head utilizing its surface tension all to concentrate on solder horn body 1, allow it can preferentially touch weld parts position, pad can have tin.When common solder horn welds down, head is circular, projection is in the horizontal plane exactly the area of its circle, the area of tin soldering liquid and the circular area of projection etc. are large, and the utility model is by after head 10 side of making into rod-like structure, when the square sloped surface 2 at its tip is welded down, its perspective plane and square sloped surface 2 etc. are large, the length of side of square sloped surface 2 is compared with the circle of same diameter, its area is greater than circular area, thus the contact surface of its welding is larger, large for part the relative position error, can better touch, ensure the success rate of welding, substantially be interposed between part between 2 millimeters and can be effectively welded to.Practice shows, when square sloped surface 2 is arranged to 30 °, is more conducive to welding operation, and its welding efficiency is also higher.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range is see claim, and when without prejudice to spirit of the present utility model, the utility model can do any type of amendment.
Claims (2)
