[0002] In order to make the products more competitive in the market, the electroplating methods of many gold-plated products have been improved from traditional liquid surface gold and jig electroplating to spot plating. During spot plating, multiple guide wheels are often required. Under the guidance of the guide wheels, the products are sent into the spot plating jig for electroplating in turn.

[0003] The existing guide wheel for spot plating comprises a wheel shaft, an upper wheel disc and a lower wheel disc. The upper wheel disc and the lower wheel disc are sleeved on the wheel shaft, and the upper wheel disc can move up and down relative to the wheel shaft.

[0004] The guide wheel needs to be adjusted before use. First, the product to be electroplated is used as a reference. Then two manufacturing personnel are required to work together to adjust it. One person fixes the product on the axle of the guide wheel, and the other tightens the bolts. This consumes a lot of man-hours. In addition, since the product material is relatively soft, it is difficult to adjust the product as a reference for height adjustment. If the adjustment is not done well, the product will not be able to enter the spot plating fixture smoothly, which will cause poor plating area or uneven film thickness, affecting the spot plating effect.
