[0002] The fan blade is used for converting the rotating mechanical energy of a motor into the flow kinetic energy of air, thereby generating a directional air flow, and finally realizing the core functions of air supply or heat dissipation. During the production and processing of the heat dissipation fan, the fan blade needs to be pressed into the fan frame and the center shaft sleeve and pin shaft and other components need to be installed, so that steps such as receiving, feeding and pressing are required. However, the existing fan blade automatic assembling device has the following problems during use. For the assembly of the fan blade, the pressing method from top to bottom is mostly used, and the feeding mechanism is used to place the accessories in the corresponding area at the center to realize automatic assembly. The existing fan blade automatic assembling device is not convenient for buffering protection and is mostly pressed hard. Due to the limitation of the production process, there are slight differences in the accuracy of the accessories. During assembly, direct hard pressing is prone to be affected by the size accuracy, which affects the quality of the finished product.

In this invention, during size adjustment, the rotation of the telescopic column can drive the buffer platform to move up and down via the guide groove and guide head. By adjusting the position of the base rod, the compression degree of the spring can be adjusted, allowing the spring to provide different buffering forces. This ensures that fan blade accessories of different specifications can receive stable support and protection during press-fitting. Through the ingenious use of the base and positioning rod, stable buffering is ensured while the positioning seat position is stable, which helps with the subsequent press-fitting positioning. There is no need to make complex adjustments to the feeding and press-fitting mechanisms. The overall device greatly improves its applicability and economic efficiency through the synchronous adjustment of size and buffering. Attached Figure Description
