Description

Technical Field

[0001] The utility model relates to an electroplating placement rack, in particular to an annular workpiece electroplating placement rack, and belongs to the technical field of electroplating. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation and improve the metal's wear resistance, conductivity, reflectivity, corrosion resistance and other properties;

[0003] A Chinese patent publication (publication number: CN 220034719 U) discloses a placement rack for electroplating of annular workpieces, which includes a placement plate and multiple groups of fixing fixtures, wherein the placement plate is slidably connected to a support plate on the upper part of an electroplating tank through a connecting plate, and is driven to rise and fall by a lifting structure, and multiple groups of the fixing fixtures are fixedly mounted on the mounting plate, including a support seat and multiple groups of limiting plates, an arc-shaped support plate is mounted on the upper part of the support seat, and multiple groups of the limiting plates are arranged along the circumference of the support seat. The utility model supports the bottom of the annular workpiece by the arc-shaped support plate, and supports and limits the side of the annular workpiece by multiple groups of abutment columns on the limiting plate, thereby solving the problem that the fixing fixtures on the current placement rack have poor adaptability to annular workpieces of different sizes and specifications, which greatly reduces the electroplating efficiency;

[0004] The above patent sets a fixed fixture, and the arc-shaped support plate and multiple groups of abutment columns in the fixed fixture support the bottom and sides of the annular workpiece, thereby completing the limited clamping of the annular workpiece, and the abutment columns can be moved and adapted according to the annular workpieces of different specifications, but there are still certain defects. The above patent drives the placement plate to descend through the lifting structure, and immerses the multiple groups of annular workpieces placed on the placement plate into the electroplating tank. At present, many electroplating processes use solution stirring to improve the quality of the coating and operating conditions. The role of stirring the plating solution is to continuously renew the cathode film, so that a fine coating can be obtained at a higher deposition rate. Stirring can also be used in very deep tanks to prevent the solution from stratifying and keep the solution concentration uniform from beginning to end. The existing more commonly used mechanical stirring devices stir the plating solution mostly by driving the stirring shaft to rotate by a motor to achieve stirring. The plating solution is basically stirred on one plane, and the upper and lower plating solutions cannot be fully stirred, so that the plating solution is not stirred evenly enough. The workpiece is easily offset by the impact of the electrolytic solution during the electroplating process, affecting the quality of the capacitor;

[0005] Therefore, a ring-shaped workpiece electroplating placement rack is proposed. Utility Model Content

[0030] By setting up the stirring device 2, the servo motor 201 drives the stirring rod 202 to rotate, and the driven gear 205 and the driving gear 207 are meshed and connected, so that the stirring rod 202 and the stirring barrel 3 rotate in opposite directions, thereby achieving the purpose of uniformly stirring the electroplating solution, and promoting the metal ions of the anode to move to the cathode, thereby accelerating the electroplating process.

[0031] Example 2

[0032] In one embodiment, a heating tube 209 is provided on the inner surface of the inner cavity of the mixing barrel 3, and support blocks 208 are fixedly connected on all four sides of the outer surface of the heating tube 209, and the support blocks 208 are fixedly connected to the inner surface of the mixing barrel 3, and a filter screen 210 is fixedly connected to the inner cavity of the mixing barrel 3 and located on the upper side of the heating tube 209, an L-shaped plate 5 is fixedly connected to the rear side of the top of the bottom plate 1, a multi-force cylinder 6 is fixedly connected to the top of the L-shaped plate 5, a cover plate 7 is fixedly connected to the bottom of the multi-force cylinder 6, a fixing device 8 is provided at the bottom of the cover plate 7, and the fixing device 8 includes a device box 801 and a clamp 802, a cavity 804 is opened on the inner surface of the device box 801, and tension springs 805 are fixedly connected to the front and rear sides of the inner surface of the cavity 804, and a fixing block 806 is fixedly connected to the outer side of the tension spring 805.

[0033] By setting up the heating tube 209, the plating liquid can be heated to a suitable temperature to increase the plating speed.
