Examples
As shown in fig. 1-3, a jig for welding a small PCB comprises a fixed base 1, a heating plate 2, a pressing mechanism and a clamping mechanism, wherein the fixed base 1 is a base for all other components and is fixed on a base surface, the heating plate 2 is installed on a working surface of the fixed base 1, and preheats a workpiece 5 to reduce thermal deformation caused by welding, the pressing mechanism tightly presses the workpiece 5 with welding on the heating plate 2, so that the workpiece 5 is fully contacted with the heating plate 2, the heating effect is improved, the workpiece 5 is pressed down by a pressing wheel 33 fixed in the pressing mechanism, the wheel-shaped structure can avoid rigid contact with the workpiece 5, and therefore the workpiece 5 cannot be damaged, the clamping mechanism fixes the workpiece 5 being welded, and hidden troubles caused by handheld welding are reduced.
As shown in fig. 1, the fixing base 1 is a base for fixing with a base, the top surface plane of the fixing base 1 is a working surface for fixing the heating plate 2, the pressing mechanism and the clamping mechanism, wherein the heating plate 2 is laid on the working surface for heating the workpiece 5, so that the tendency of thermal defects caused by welding is reduced, at least two workpieces 5 can be placed in the length direction of the heating plate 2, and the specific length can be flexibly adjusted according to the actual working condition.
The pressing mechanism is close to one end of the heating plate 2 and used for fixing the workpieces 5 to be welded, as the heating plate 2 can simultaneously accommodate two or more workpieces 5, the workpieces 5 to be welded are fixed by the pressing mechanism, so that the number of the pressing mechanisms is also multiple, the pressing mechanism comprises a fixed beam 31, mounting rods 32 and pressing wheels 33, as shown in figure 2, the fixed beam 31 is parallel to the heating plate 2, the mounting rods 32 are arranged on the fixed beam 31 in parallel, the mounting rods 32 are simultaneously parallel to the heating plate 2, the bottom of the mounting rods 32 is fixed with the pressing wheels 33, as shown in figure 3, the pressing wheels 33 are consistent in height and parallel to the length direction of the heating plate 2, so that the movement of the workpieces 5 in the length direction of the heating plate 2 is not hindered, the workpieces can move to the clamping mechanism in the length direction of the heating plate 2, the pressing wheels 33 are contacted with the workpieces 5, and the workpieces 5 are tightly pressed to the heating, make the contact more abundant, work piece 5 also can obtain abundant heating consequently, pinch roller 33 surface is the rubber material comparatively soft, is not the rigidity contact with work piece 5, consequently work piece 5 also can not leave the mar at pinch roller 33 lower motion, and is littleer to work piece 5 influence.
