The invention relates to an automatic crimping device for crimping HPLC communication modules of an electric energy meter. According to the device, the limitations of various wire bodies are overcome,and manual work is replaced by adopting an air cylinder driven crimping device for automatic crimping; probes required by various communication modules are installed and are arranged in a staggered mode respectively, so that the purpose that the device is compatible with various communication modules is achieved; the probes are arranged in 16 groups of 4 multiplied by 4 so as to achieve the purpose of simultaneously crimping sixteen HPLC communication modules of the same electric energy meter.
