[0002] The horizontal electroplating feeding device for PCB boards is a device used in the production process of PCB (Printed Circuit Board). It is usually used to place PCB materials in the electroplating tank for electroplating. This device can automatically transport PCB materials to the electroplating tank, thereby achieving efficient production.

A chute is provided at one end of the machine, the material transport cart is provided with rollers that match the chute, and a driving mechanism is provided under the material transport cart. The driving mechanism drives the material transport cart to move along the chute. A conveyor belt is provided at the end of the machine away from the material transport cart, and a rotating mechanism is provided at the end of the conveyor belt close to the chute. The rotating mechanism drives the PCB board from an upright state to a flat state. A telescopic cylinder is provided at the middle position of the machine near the flap.

The utility model solves the problem that the feeding device cannot clean the conveying mechanism of the feeding device when feeding the PCB material, resulting in the impurities on the conveying mechanism affecting the electroplating of the PCB material.

[0011] Preferably, two movable rods are symmetrically welded at the bottom of the fixed sleeve, and two movable holes are symmetrically opened at the bottom of the fixed frame, and the bottoms of the two movable rods pass through the two movable holes. The two movable rods limit the fixed sleeve, and when the brush head on the top of the fixed sleeve cleans the surface of the feeding belt, the friction force generated will drive the fixed sleeve to shake, and the two movable rods reduce the shaking of the fixed sleeve.

[0012] Preferably, the bottoms of the two movable rods are both provided with stoppers, and the outer diameters of the two stoppers are larger than the inner diameters of the two movable holes. The two stoppers prevent the two movable rods from sliding out of the two movable holes.
