Description

Technical Field

[0001] The utility model belongs to the technical field of electroplating, in particular to an electroplating crane mechanism. Background Art

[0002] Electroplating is a common workpiece processing technology. It uses the principle of electrolysis to coat the surface of the workpiece with a layer of metal or alloy film, thereby enhancing its corrosion resistance and aesthetics. During the electroplating process, in order to facilitate the transportation of the workpiece, a crane mechanism is usually used to transport the workpiece between the electroplating tank and other equipment.

[0003] The document with the existing announcement number CN219280087U discloses a traveling crane for electroplating, comprising a support plate and a fixed box arranged above the support plate, two fixed frames are symmetrically fixed to the surface of the support plate, a rotating motor is installed on one side of the fixed frame, and the output end of the rotating motor is fixedly connected to a lead screw, the fixed box is threadedly connected to the lead screw, the bottom of the fixed box is movably connected to a protective box, a rotating shaft is rotatably connected to the inside of the protective box, the bottom of the rotating shaft is fixedly connected to a connecting frame, the bottom of the connecting frame is fixedly connected to a material barrel, the outer surface of the material barrel is sleeved with a water-blocking sleeve, and a connecting block is fixedly connected between the water-blocking sleeve and the material barrel;

[0004] However, it still has the following disadvantages in actual use:

[0005] In the above-mentioned electroplating crane, the material barrel is mounted on a fixed box via a connecting frame, a rotating shaft, and other structures, and the fixed box is moved by a lead screw. However, during use, there is no structure to limit the material barrel, resulting in the material barrel shaking during transportation, causing the workpieces inside to collide with each other, thereby affecting the yield of the workpieces.

[0006] The above-mentioned crane used for electroplating drives the material barrel to rise and fall through a rotating shaft and a connecting frame. However, during use, it is not convenient to position the lifting of the material barrel, which affects the immersion depth of the material barrel in the electroplating tank and further affects the electroplating effect of the workpiece.

[0007] To this end, we provide a electroplating crane mechanism to solve the above problems. Utility Model Content
