Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment, in particular to an electroplating device for ceramic metallization. Background Art

[0002] During the metallization chemical nickel plating process of ceramics, the ceramics need to be immersed in a nickel pool through a hanger, and then nickel is plated on the ceramics through an electrochemical reaction. The electroplating hanger is the main factor affecting the quality and efficiency of ceramic chemical plating. The existing method is to put a nickel wire on the ceramic and make the nickel wire form a single-point contact with the electroplating position, but this method is inefficient. At the same time, the single-point contact between the nickel wire and the electroplating position further prolongs the electroplating efficiency, which ultimately leads to high electroplating costs for ceramics. At the same time, it cannot meet the current large-scale, high-quality electroplating of vacuum arc chamber shells.

[0003] Based on the above technical problems, in the prior art, publication number CN217997394U discloses a ceramic metallization electroplating device, including a fixture, and a rotating shaft arranged thereon, the rotating shaft is provided with a fixture and can drive the fixture to rotate; the fixture includes two clamp arms of a frame structure, one end of the two clamp arms is connected to each other, and the other end forms an open end, the two clamp arms are used to clamp the ceramic tube and electrically contact the electroplating area of ​​the ceramic tube; the clamp is driven to rotate by the rotating shaft, and electroplating is realized during the rotation process, and the plating solution is stirred at the same time, so as to realize indirect electroplating and improve the electroplating efficiency of the ceramic tube, and the clamp arms of the frame structure are adopted, while the contact area between the clamp arms and the ceramic tube is minimized, the stability of the clamping of the ceramic tube is ensured. The use of this clamp reduces the manual turning over during the electroplating process, greatly improves the production efficiency, reduces the labor intensity of the operator, and has the advantages of high efficiency, uniform coating, good reliability, etc.

[0004] In the above scheme, the output gear, secondary gear, primary gear and input gear are all installed in the fixture, and are immersed in the electroplating solution along with the ceramic tube when the fixture is extended into the nickel pool. Over time, it is very likely that irregular electroplating layers or electroplating slag will be formed between the gears, thereby affecting the transmission effect of the rotating shaft.

[0005] To this end, a ceramic metallization electroplating device is proposed, which has the advantage of preventing the transmission mechanism from being disturbed by electroplating, thereby solving the problems in the above-mentioned background technology. Utility Model Content

[0014] In the utility model, a support platform, a driving box, a motor, a transmission shell, a transmission belt, a hydraulic rod, a transmission shaft, and a clamp are adopted. By starting the motor in the driving box, the output end of the motor drives the transmission belt to rotate under the action of a pulley, and then another pulley wound with the transmission belt drives the transmission shaft to rotate, so that the two clamps fixed on the transmission shaft rotate in the electroplating liquid of the nickel pool, so as to achieve the purpose of uniform electroplating of the ceramic tube in the clamp. Compared with the existing ceramic electroplating device, the transmission belt can be hidden due to the setting of the transmission shell, so as to eliminate the interference of the electroplating liquid on the transmission structure. At the same time, by starting the hydraulic rod fixed to the side wall of the nickel pool, the hydraulic rod is prompted to lift the driving box in the extended state, so that the driving box drives the transmission shell and the transmission shaft to move upward synchronously, which provides convenience for loading and unloading of ceramic tubes.

[0015] In the utility model, a ceramic tube clamp is formed by two annular members with seating openings and three contact rods fixed on the inner sides thereof. Since two V-shaped inner recesses are arranged on the annular members of the clamp regarding the seating openings, and a plurality of limit members are welded on the inner ring of the annular members of the clamp, and handles are welded on the two annular members of the clamp, the two handles of the clamp are pulled apart to cause the inner recesses of the clamp to deform, so that the seating opening of the clamp becomes larger, so that the ceramic tube can be seated and contacted with the three contact rods on the inner side of the clamp. Under the action of the plurality of limit members, the ceramic tube is limited, so as to achieve the purpose of firmly clamping the ceramic tube. Compared with the existing ceramic tube clamping structure, the amount of one contact rod can be reduced, thereby further reducing the contact area between the clamp and the ceramic tube, which is beneficial to the full electroplating of the ceramic tube.
