Abstract
The utility model discloses a reflow welding jig locating with a high accuracy, comprising a locating base, a locating plate, a locating column and a bolt, wherein a thread is arranged on the root of the locating column; at least one first through hole penetrating the upper surface and the lower surface is formed on the locating base; a bulge for supporting the locating column is arranged on the inner wall of the first through hole; the locating plate is fixed on the locating base and provided with a second through hole corresponding to the first through hole in position and as the same as the locating column in diameter; the locating column sequentially penetrates through the second through hole and the first through hole; and the locating column is fixed in the first through hole via the bolt.
Description
Technical field
The utility model relates to the wiring board production technical field, is specifically related to a kind of reflow soldering tool of hi-Fix.
Background technology
As shown in Figure 1, SMT (Surface Mount Technology has generally all been merged in the wiring board production of prior art, surface mount or surface mounting technology) and two kinds of production technologies of wiring board plug-in unit welding, SMT a kind ofly will (be called for short SMC/SMD without pin or short leg surface-assembled components and parts, Chinese title sheet components and parts) be installed in FPC(Flexible Printed Circuit, Flexible Printed Circuit) or PCB(Printed circuit board, printed circuit board) on surface or the surface of other substrate, by the Reflow Soldering method circuit load technology of welding assembly in addition, after partly finishing, SMT again the wiring board plate is carried out the plug-in unit welding, that the welding of FPC plate or pcb board plug-in unit all needs corresponding tool that product to be welded is positioned, can reflow soldering tool and Wave soldering fixture accurately locate welding product, whether sturdy and durable, whether meet environmental requirement, to efficient and the quality important of wiring board production.The reflow soldering tool of prior art comprises positioning base and the pallet that is placed on the positioning base, pallet positions by the reference column that is installed on the positioning base upper surface, the mounting means of prior art reference column is at first to determine the installation site of reference column on positioning base, at this installation site processing blind hole, by mechanical force reference column is wedged blind hole, because the thickness of positioning base is generally all more than 2cm, so processing blind hole, accurately locate very difficult to the relative position of a plurality of blind holes, and by mechanical force reference column is wedged blind hole, the physical deformation of reference column is inevitable, this also produces harmful effect to the location of pallet, so the positioning base of prior art can not carry out hi-Fix to pallet and wiring board.
The utility model content
The technical problems to be solved in the utility model provides a kind of reflow soldering tool of hi-Fix, therefore the reflow soldering tool that overcomes prior art is wedged reference column by mechanical force the blind hole of positioning base, can not carry out to pallet and wiring board the defective of hi-Fix.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
A kind of reflow soldering tool of hi-Fix, comprise positioning base, location-plate, reference column and bolt, the root of described reference column is provided with screw thread, be provided with the first through hole that at least one penetrates top and bottom on the described positioning base, the first through-hole wall is provided with the projection that supports described reference column, described location-plate is fixed on the described positioning base and is provided with the second through hole that the position is corresponding with the first lead to the hole site and diameter is identical with described reference column, described reference column passes the second through hole and the first through hole successively, and described bolt is fixed on described reference column in the first through hole.
The reflow soldering tool of described hi-Fix, wherein said location-plate is made as steel disc.
The reflow soldering tool of described hi-Fix, wherein said projection is made as protruding ring.
The beneficial effects of the utility model: the utility model has changed the pattern that the through hole of prior art by positioning base positions reference column, by the through hole on the location-plate reference column is positioned, because the processing of the through hole of location-plate is very easy to guarantee very high precision, behind the reference column location, do not need mechanical force reference column to be fixed in the blind hole of positioning base, but reference column is bolted in the through hole of positioning base, can not cause the physical deformation of reference column, can guarantee like this zero tolerance assembling, the positioning accuracy of reference column is reached below the 0.02mm, thereby guaranteed the hi-Fix to pallet and wiring board, improved the wiring board welding quality of production.
Description of drawings
The utility model comprises following accompanying drawing:
Fig. 1 is prior art wiring board production procedure schematic diagram;
Fig. 2 is the utility model schematic diagram.
Embodiment
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings:
As shown in Figure 2, the reflow soldering tool of the utility model hi-Fix comprises positioning base 11, location-plate 12, reference column 13 and bolt, the root of reference column 13 is provided with screw thread, be provided with the first through hole 111 that at least one penetrates top and bottom on the positioning base 11, the first through hole 111 inwalls are provided with the projection of supporting and location post 13, location-plate 12 is fixed on the positioning base 11 and second through hole 121 identical with reference column 13 that be provided with position and diameter corresponding with the first through hole 111 positions, reference column 13 passes the second through hole 121 and the first through hole 111 successively, and bolt is fixed on reference column 13 in the first through hole 111.Described location-plate is made as steel disc.Location-plate 12 is made as steel disc in specific embodiment of the utility model.Projection in the first through hole 11 is made as protruding ring.
Those skilled in the art do not break away from essence of the present utility model and spirit, can there be the various deformation scheme to realize the utility model, the above only is the better feasible embodiment of the utility model, be not so limit to interest field of the present utility model, the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, and all is contained within the interest field of the present utility model.
