TECHNICAL FIELD The present application relates to the technical field of circuit board electroplating, and in particular to a feeding device for a circuit board and an electroplating equipment. BACKGROUND In the current printed circuit board (PCB) manufacturing process, the effect of the first layer of electroplating often fails to meet the ideal standard, resulting in the need for second layer of electroplating. The ideal electroplating effect usually requires thin-layer electroplating first, followed by thick-layer electroplating. To achieve this goal, the existing electroplating method usually uses a horizontal electroplating machine. Before the boards enter the electroplating machine, they are required to be arranged side by side and maintain a certain spacing. However, most equipment uses a roller conveyor structure, resulting in insufficient spacing control accuracy, usually only 10-15 mm. If the positioning is inaccurate, the plating thickness will cause tilt problems, which will affect the final electroplating quality and lead to low production efficiency.
