This utility model relates to the field of conformal coating production technology and discloses an additive dispensing device for conformal coating production. The device includes a mixing tank with three supporting legs arranged circumferentially at the bottom. A first motor is mounted on the top of the mixing tank. This additive dispensing device uses a control device to control a second motor to drive a winding device in forward and reverse rotation. The winding device winds or releases a pull rope, which in turn causes a baffle to slide inside the feed cylinder, thereby controlling the amount of additive dispensed. Simultaneously, a flow sensor monitors the additive flow rate in real time and feeds the data back to the control device. The control device controls the second motor according to a preset dispensing amount, achieving precise dispensing, significantly reducing manual operation, improving the performance stability of the conformal coating, and reducing batch-to-batch product performance differences.
