The invention discloses a production process of an intelligent door lock, which comprises the following specific steps: mounting an internal driving mechanism, mounting a bottom plate assembly, pasting an ESD (Electro-Static Discharge) gasket, mounting a button ring, mounting a pin column, applying lubricating oil and mounting a button, so that the assembly work of the intelligent door lock is completed, and the whole set of assembly process is completed through full-automatic intelligent door lock assembly equipment. According to the pin column mounting device, the working efficiency is greatly improved, the supply requirement of the market is met, a traditional manual assembly production mode is changed, the automation degree is high, the size of the needed pin column can be tested through the depth testing mechanism, then the needed pin column is blanked and finally mounted through the pin column selecting and mounting mechanism, the automation degree is high, and the production efficiency is improved. The button assembling device is simple in structure and high in yield, the technical problem that the traditional defective product rate is high due to assembling errors is solved, the rotary positioning device can adjust the button to be assembled to the needed accurate position, and therefore the clamping requirement of follow-up assembling is met.
