Coating module and manufacturing equipment of reference electrode

The utility model provides a coating module and manufacturing equipment of a reference electrode. A containing cavity and a penetrating channel are formed in the coating module; the accommodating cavity is used for accommodating slurry; the penetrating channel is communicated with the containing cavity, the penetrating channel is used for allowing the base material to penetrate into the containing cavity so that the base material can make contact with the slurry, the containing cavity is provided with a discharging port, and the discharging port is used for allowing the base material to penetrate out of the containing cavity. The base material enters the containing cavity from the penetrating channel and then makes contact with the slurry in the containing cavity, the peripheral face of the base material is coated with the slurry along with the base material penetrating out of the containing cavity, coating is convenient, all slurry coating in the circumferential direction of the base material can be achieved
