[0038] In some embodiments, a positioning hole 311 is provided on the slide plate 31. An assembly device provided in an embodiment of the utility model further includes a positioning column 102, which is provided on the movable plate 71. After the positioning column 102 passes through the positioning hole 311, the slide plate 31 can move along the length extension direction of the positioning column 102. In the actual assembly process, when the movable plate 71 moves to the bottom of the slide plate 31 along the slide rail 61 under the drive of the displacement driving member 62, the positioning column 102 will face the corresponding positioning hole 311. In the process of the push rod 21 of the upper mold driving member 2 driving the slide plate 31 to move in the direction close to the movable plate 71, the positioning column 102 will pass through the positioning hole 311, so that the slide plate 31 can move along the length extension direction of the positioning column 102, which is conducive to improving the stability and accuracy of the assembly process.

Since the linkage block 622 is connected to the movable plate 71, the movable plate 71 will also move accordingly, so that the driving force of the displacement driver 621 can be stably transmitted to the movable plate 71, thereby driving the positioning plate 8 and the heating insert 10 to move to the specified position.

[0041] As an implementation mode, an assembly device provided by the embodiment of the utility model further includes a heating rod 103 and a thermocouple 104. The heating rod 103 is arranged inside the positioning plate 8, that is, the interior of the positioning plate 8 has a space for accommodating the heating rod 103, such as the interior of the positioning plate 8 is provided with an installation cavity penetrating the positioning plate 8, so that the heating rod 103 can be inserted into the interior of the installation cavity.

The thermocouple 104 is connected to the heating rod 103, and the heating rod 103 can heat the heating insert 10 through the control of the thermocouple 104. During the assembly process, when the positioning plate 8 drives the watch base to move to a position opposite the clamping assembly 5, the heating rod 103 starts to work, and the heating temperature and heating time of the heating rod 103 are controlled by the thermocouple 104. Under the heating of the heating rod 103, the temperature of the heating insert 10 gradually rises to a suitable working temperature.

During the assembly process, when the positioning plate 8 drives the watch base to move to a position facing the clamping assembly 5, the first heating element 10a and the second heating element 10b will move to the side of the watch base under the drive of the second elastic member 9 and heat it. Since the first positioning platform 83 is located between the first heating element 10a and the second heating element 10b, it can be ensured that the heating insert 10 uniformly heats the buckle ring and the side of the watch base during the heating process. At the same time, the provision of the second elastic member 9 will allow the heating insert 10 to have a certain degree of freedom of movement in the through groove 81, and can be adaptively adjusted according to the actual position and shape of the watch base, which is conducive to improving the assembly accuracy and efficiency, and ensuring the stability and reliability of the assembly process.
