More Information
Summary:The invention provides a film-coating device for a resistive film of a potentiometer. The device is used for sending a first control instruction to a movement drive module and sending a second control instruction to a spraying control module; the movement drive module is used for controlling the running of a motor according to the received first control instruction, so as to drive a potentiometer base body to run; and the spraying control module is used for controlling the spraying of a spray gun according to the received second control instruction, thus realizing the aim that the spray gun is automatically controlled to spray the potentiometer base body. Due to the high accuracy of automatically-controlled spraying, the spraying effect on the resistive film is improved, and then the linearity of the potentiometer is improved and the quality of the potentiometer is ensured.
