Description

Assembly jig for heart rate lens of watch Technical Field The utility model relates to the technical field of jigs, in particular to an assembly jig for a watch heart rate lens. Background 90% Of smart watches on the current market have heart rate monitoring functions, and heart rate lenses for monitoring heart rate are mostly round. Because the bottom shell and the heart rate lens of the watch are mostly round, the positioning difficulty of the bottom shell and the heart rate lens is high, and the watch can be assembled manually only by manpower, so that the efficiency is low, more users can use the watch, and the phenomenon of dislocation and uneven assembly of the heart rate lens can be caused. Disclosure of Invention The utility model aims to solve the problem of providing an assembly jig for a heart rate lens of a watch, which improves the assembly efficiency and ensures that the heart rate lens is installed in place. The assembly jig comprises an outer die holder, an inner die core, a bottom plate and an elastic piece, wherein an annular limiting part is arranged at the top of the outer die holder, a watchcase positioning molded surface is arranged on the inner side of the annular limiting part, a movable cavity is arranged at the bottom of the outer die holder, a through hole communicated with the movable cavity is formed in the top of the outer die holder in a penetrating manner, the inner die core comprises a substrate movably arranged in the movable cavity and matched with the movable cavity, a core column connected to the top of the substrate and matched with the through hole, the core column is movably arranged in the through hole, the top of the core column is provided with the lens positioning molded surface, the bottom plate is detachably connected to the bottom of the outer die holder, and the elastic piece is arranged in the movable cavity and is abutted between the substrate and the bottom plate. Preferably, the opposite sides of the annular limiting part are provided with clearance notches. Preferably, the elastic member is a spring. Preferably, the outer die holder is connected with the bottom plate through screws. The watch heart rate lens assembling jig has the beneficial effects that the watch case positioning molded surface and the lens positioning molded surface are respectively matched with the shapes of the bottom of the watch case and the bottom of the heart rate lens, when the watch is assembled, the watch case is firstly placed on the watch case positioning molded surface to position the watch case, then the heart rate lens is placed on the lens positioning molded surface to position the heart rate lens, downward pressure is applied to the heart rate lens, and the inner mold core compresses the elastic piece and moves downwards until the heart rate lens is assembled on the watch case. After the heart rate lens is released, the inner mold core is reset under the action of the elastic force of the elastic piece, and the watchcase is separated from the watchcase positioning molded surface, so that the product can be taken away from the jig. The heart rate lens assembling device is simple in structure, can effectively improve assembling efficiency, saves labor, and ensures that the heart rate lens is installed in place.
