[0006] The cam is adapted to move the upper mold member toward the lower mold member and to move the upper mold member toward the lower mold member so as to press the upper mold member against the lower mold member. As a result, the cam is adapted to move the upper mold member toward the lower mold member and to move the upper mold member toward the lower mold member. As a result, the cam is adapted to move the upper mold member toward the lower mold member and to press the upper mold member against the lower mold member. As a result, the cam is adapted to move the upper mold member toward the lower mold member and to press the upper mold member against the lower mold member. As a result, the cam is adapted to move the upper mold member toward the lower mold member and to press the upper mold member against the lower mold member. As a result, the cam is adapted to move the upper mold member toward the lower mold member and to press the upper mold member against the lower mold member. As a result, the cam is adapted to move the upper mold member toward the lower mold member and to press the upper mold member against the lower mold member. The watch assembly device of the utility model can improve the alignment accuracy and installation efficiency of the watch base and the watch middle frame, and completes the assembly process of the watch by forming a one-time mold closing with the upper mold and the lower mold. The operation is convenient and the problem of poor assembly accuracy is improved.

[0007] Furthermore, the second groove extends vertically, and an annular placement platform protrudes from the sidewall of the second groove. The annular placement platform forms a placement position for the annular middle frame on a side facing the upper mold. The retraction drive device drives the movable block to movably penetrate the annular placement platform in the vertical direction. When the upper mold moves vertically toward the lower mold to close the mold, the middle frame to be assembled is placed on the annular placement platform. When the movable block moves downward under the pressure of the upper mold, the middle frame of the watch can be attached to the outer ring of the watch bottom case, achieving adhesive assembly and fixation of the watch bottom case and the watch middle frame. At this time, the retraction drive device drives the movable block to retract in the direction close to the base until it penetrates the second groove, separating the watch bottom case from the movable block.

[0008] Furthermore, a module mounting seat is provided on a protruding surface of the movable block facing the upper mold, and the cross-sectional area of ​​the module mounting seat is smaller than that of the movable block. The module mounting seat is used to place a watch functional module to be assembled, such as a heart rate test module. When the upper mold moves vertically toward the lower mold to form a closed mold, the movable block moves downward under the pressure of the upper mold until the middle frame of the watch fits against the outer ring of the bottom case of the watch. Since the cross-sectional area of ​​the module mounting seat is smaller than that of the movable block, the movable block and the module mounting seat continue to pass through the annular middle frame placement position. At this time, the bottom case of the watch is separated from the movable block and mounted on the middle frame placement position. The watch functional module continues to move downward until it is embedded in the bottom case of the watch. The upper mold and the lower mold are used to form a one-time closed mold to complete the two assembly processes of the watch.

[0009] Furthermore, when the movable block protrudes from the second groove and is stationary, the vertical distance between the surface of the movable block facing the upper mold and the annular middle frame placement position is no less than the height of the middle frame to be attached. The distance between the movable block and the annular placement platform is defined so that the watch bottom case to be assembled can be moved into position during downward movement. The watch bottom case to be assembled moves downward until it is blocked by the annular placement platform and disengages from the movable block, allowing the middle frame to be attached to the outer surface of the watch bottom case to be assembled.

[0010] Furthermore, the watch assembly device further includes a vertically arranged spring, one end of which is fixed to the retraction drive device, and the other end of which is fixed to the surface of the movable block facing the bottom of the first groove. One end of the spring is fixed to the bottom of the first groove, and the other end is fixed to the movable block. When the upper mold moves vertically toward the lower mold to form a closed mold, the movable block moves downward under the pressure of the upper mold. As the spring is squeezed, the upper mold and the lower mold are tightly pressed together under the action of elastic potential energy. As the upper mold is further pressed together, the movable block continues to move downward until the watch functional module located on the module mounting seat continues to move downward until it is embedded in the watch bottom case. When assembly is complete, the retraction drive device drives the movable block and the spring to retract in a direction close to the base, separating the movable block from the watch bottom case.

[0011] Furthermore, the number of the springs is several and the springs are symmetrically arranged. The several symmetrically arranged springs provide uniform elastic force, so that the movable block is subjected to uniform force.

[0012] Furthermore, a watch profiling mold is provided on one side of the upper mold facing the lower mold. The watch profiling mold is used to tightly fit the watch profiling mold with the upper surface of the middle frame, the watch bottom case and the watch functional module when the upper mold and the lower mold are closed to ensure that the watch profiling mold moves into place.

[0013] Furthermore, the upper mold driving device includes a vertical track, a vertical connecting block, and a vertical drive motor; the vertical track is disposed on the base, the vertical connecting block is movably disposed on the vertical track, and the vertical drive motor drives the vertical connecting block to move along the extension direction of the vertical track; the upper mold is fixed to the vertical connecting block. The vertical drive motor drives the vertical connecting block to move along the extension direction of the vertical track to drive the upper mold to move vertically toward the lower mold to form a closed mold.

[0014] Furthermore, a vertical positioning mechanism is provided between the upper die and the lower die, through which the upper die moves in a vertical direction and is aligned with the lower die.

[0015] Furthermore, the vertical positioning mechanism includes a vertical positioning post and a vertical positioning hole. One of the protrusions in the upper mold or the lower mold is provided with a vertical guide post, and the other of the upper mold or the lower mold is provided with a vertical positioning hole. The vertical positioning post can be inserted into the vertical positioning hole. The vertical positioning post cooperates with the vertical positioning hole to achieve alignment between the upper mold and the lower mold.
