[0002] Digital key is a new type of car key technology, which refers to keyless entry and starting of the car through smart terminal devices such as smartphones and wearable devices, thereby providing a safer and more convenient car experience.

[0003] The digital key is mainly composed of a base and a cover. After the base and the cover are assembled, a cavity for accommodating the circuit board is formed inside. The base and the cover are processed separately and need to be assembled and connected and fixed before the finished digital key can be obtained. At present, in the production process of digital keys, the existing technology usually requires the use of multiple devices to solder, assemble and weld the digital keys separately. Due to the need to frequently replace equipment, the transfer time is long, which seriously affects the production efficiency and increases the production cost. In addition, in order to ensure the normal function of the digital key, it needs to be ATE tested after its assembly and connection are completed. The existing technology usually has a separate ATE test equipment, which is used to test the digital key product after welding is completed, but transferring the product to the test equipment also takes a certain amount of time, which is inefficient.
