Description

[0002] Generally, the electroplating solution needs to deposit metal onto the surface of a conductive object by electrolysis to achieve the purpose of electroplating. Electroplating usually involves using the object to be electroplated as a cathode or anode, and then immersing it in an electrolyte containing metal ions. The metal ions are deposited on the surface of the object by applying an external voltage to form a metal coating.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Refer to the instruction manual Figure 1-9 , an electroplating device for processing a vacuum pump impeller according to an embodiment of the present invention, such as Figure 1 As shown, it comprises an electroplating mechanism 1, a limiting mechanism 2 is fixedly installed inside the electroplating mechanism 1, and a friction stirring mechanism 3 is rotatably installed on the top of the limiting mechanism 2;

[0031] Reference Figure 2-4As shown, the friction stirring mechanism 3 includes a second limiting sleeve 31 arranged on the top of the electroplating mechanism 1, and a plurality of reciprocating threaded screws 32 are rotatably installed on the outer wall of the second limiting sleeve 31, and a plurality of first guide slide rods 33 parallel to the reciprocating threaded screws 32 are fixedly connected to the outer wall of the second limiting sleeve 31, and the outer walls of the plurality of reciprocating threaded screws 32 are threadedly connected to directional sleeves 34 slidably connected to the first guide slide rods 33, and the bottom of the directional sleeve 34 is rotatably connected to a guide frame 35, and a limiting strut 36 arranged in a horizontal state is fixedly installed inside the guide frame 35, and two connecting sleeve rods 37 are slidably installed on the outer wall of the limiting strut 36, and the bottom of the two connecting sleeve rods 37 is rotatably connected to a rubber stirring rod 38, and the two connecting sleeve rods 38 are rotatably connected to the rubber stirring rod 38. A telescopic spring 39 fixedly connected to the limiting strut 36 is fixedly installed on one side of the second limiting sleeve 31, wherein a power assembly for driving the plurality of reciprocating threaded screws 32 to rotate is provided inside the second limiting sleeve 31, and at the same time, the plurality of reciprocating threaded screws 32 and the first guide slide bar 33 are arranged in a circular shape around the outer wall of the second limiting sleeve 31 in an equidistant state in sequence. In actual use, the number of the reciprocating threaded screws 32 is usually consistent with the number of common impeller blades. Under normal conditions, the two telescopic springs 39 are in an extended state on the side of the limiting strut 36 away from the guide frame 35 to press the connecting sleeve rod 37 to a side position close to the guide frame 35. At this time, the distance between the two connecting sleeve rods 37 and the corresponding two rubber stirring rods 38 is relatively close.

[0032] When in actual use, the two rubber stirring rods 38 can be respectively limited and fitted on both sides of the impeller blades. According to the thickness of the blades, the two rubber stirring rods 38 can be pressed against each other, so that the two connecting sliding sleeve rods 37 can slide synchronously on the outer wall of the limiting support rod 36, so as to be suitable for limiting the impeller blades of different thicknesses. After that, the directional sliding sleeve 34 can drive the guide frame 35 and the limiting support rod 36 to translate on the outer wall of the reciprocating threaded screw 32 by rotating the reciprocating threaded screw 32, so that the rubber stirring rod 38 can be moved on the outer wall of the blade, thereby promoting the reaction between the metal ions in the electrolyte and the impeller surface, which helps to enhance the rate and efficiency of the electroplating reaction, shorten the electroplating time, and improve production efficiency.

[0033] In a specific implementation, by driving the reciprocating threaded screw 32 to rotate, the directional sleeve 34 drives the guide frame 35 and then drives the rubber stirring rod 38 to perform translational movement as a whole. When the impeller blades are in the shape of straight sheets, the two rubber stirring rods 38 can be synchronously moved along the outer walls of both sides of the straight blades to contact the outer walls of the blades, so as to transport the metal ions in the electrolyte in the inner cavity of the electroplating mechanism 1 to the vicinity of the surface of the impeller blades, thereby increasing the concentration of metal ions on the surface of the impeller blades, promoting the diffusion and deposition of metals, thereby accelerating the electroplating process, and thus improving the quality and consistency of the electroplated products. When the impeller blades are in the shape of an arc, by combining the guide frame 35 rotating at the bottom of the directional sleeve 34, the two rubber stirring rods 38 can be synchronously moved along the outer walls of the two sides of the straight blades to contact the outer walls of the blades, so as to transport the metal ions in the electrolyte in the inner cavity of the electroplating mechanism 1 to the vicinity of the surface of the impeller blades, thereby increasing the concentration of metal ions on the surface of the impeller blades, promoting the diffusion and deposition of metals, thereby accelerating the electroplating process, and thus improving the quality and consistency of the electroplated products. The setting enables the rubber stirring rod 38 to rotate along the outer shape trajectory of the impeller blade when it moves in contact with the outer wall of the impeller blade, and as the blade curvature gradually bends, the reciprocating threaded screw 32 as a whole can drive the second limiting sleeve 31 to rotate as a whole when the rubber stirring rod 38 gradually moves away from the second limiting sleeve 31, thereby enabling the rubber stirring rod 38 to always be in contact with both sides of the impeller, and the electrolyte is evenly coated on the outer wall of the blade, thereby avoiding uneven electroplating of the blade and the problem of dead corners in the bent blade. When the device is used for electroplating, it can be used for impellers of different shapes and specifications, making it more convenient to use and more universal.

[0034] Further, see Figure 8-9 As shown, a plurality of second support brackets 310 are fixedly mounted on the outer wall of the second limiting sleeve 31, and both sides of the plurality of second support brackets 310 are rotatably connected to third support brackets 311, and a guide rack 312 is fixedly connected inside the third support bracket 311, and one side of the guide rack 312 is meshed with a first gear ring 313 fixedly connected to the rubber stirring rod 38. The purpose of such a setting is that when the rubber stirring rod 38 is driven to move, the mutual meshing of the guide rack 312 and the first gear ring 313 can drive the rubber stirring rod 38 to rotate as a whole on the outer wall of the blade, wherein, in combination with Figure 7As shown, an auxiliary bearing tray 314 rotatably connected to the rubber stirring rod 38 is rotatably installed at the bottom of the first gear ring 313, and a second guide slide bar 315 is fixedly installed on the top of the auxiliary bearing tray 314. A rectangular slide groove 316 is provided at the bottom of the guide rack 312, and the second guide slide bar 315 is slidably installed in the inner cavity of the rectangular slide groove 316. When the rubber stirring rod 38 moves as a whole, the auxiliary bearing tray 314 can be driven to slide on the bottom of the guide rack 312 through the second guide slide bar 315, so that the first gear ring 313 always maintains a limited connection state with the guide rack 312, and then when the first gear ring 313 moves to one side of the guide rack 312, it drives the rubber stirring rod 38 to rotate synchronously, thereby exerting a friction effect on the outer wall of the impeller blade, and simultaneously stirring the electrolyte around the blade, so as to more evenly distribute the metal ions in the electrolyte, thereby increasing the coverage of the metal on the impeller surface, ensuring that the entire impeller surface can be evenly electroplated, and reducing the dead angles and gaps on the surface.

[0035] Further, see Fig. 9 As shown, a second gear plate 318 fixedly connected to the third support bracket 311 is rotatably installed at the connection between the third support bracket 311 and the third support bracket 311, and a first gear plate 317 meshing with the second gear plate 318 is fixedly installed on one side of the third support bracket 311. The purpose of this arrangement is that when used for arc-shaped blades, as the rubber stirring rod 38 drives the reciprocating threaded screw 32 to deflect as a whole, it can synchronously drive the first gear ring 313 to rotate, and then drive the guide rack 312 and the third support bracket 311 to rotate around the connection with the second support bracket 310, so that the second gear plate 318 synchronously rotates and moves on the outer wall of the first gear plate 317, so that there is a certain resistance to the overall deflection movement of the third support bracket 311 and the guide rack 312, and then keep the guide rack 312 always in contact with the outer wall of the first gear ring 313 and move synchronously with the displacement of the first gear ring 313.

[0036] Further, see Figure 8-9As shown, the power assembly includes an electric rotating plate 319 rotatably mounted inside the second limiting sleeve 31, a second gear ring 320 is fixedly mounted on the top of the electric rotating plate 319, and one end of a plurality of reciprocating threaded screws 32 extending into the inner cavity of the second limiting sleeve 31 is fixedly connected to a third gear plate 321, and a plurality of third gear plates 321 are arranged on the top of the electric rotating plate 319 and mesh with the second gear ring 320. The purpose of such a setting is that when the electric rotating plate 319 is started to rotate, the second gear ring 320 can be rotated to drive the plurality of third gear plates 321 to rotate synchronously, thereby driving the plurality of reciprocating threaded screws 32 to rotate synchronously, so that the two rubber stirring rods 38 corresponding to the bottom of the plurality of reciprocating threaded screws 32 are both fitted to the outer wall of the blade and move.

[0037] Further, see Figure 5 and Figure 3 As shown, the limiting mechanism 2 includes a second positioning plate 21 arranged at the bottom of the second limiting sleeve 31, and the top of the second positioning plate 21 is fixedly connected to the first limiting sleeve 22 rotatably connected to the second limiting sleeve 31, and the outer wall of the first limiting sleeve 22 is provided with a plurality of limiting clamping plates 23 slidably connected to the second positioning plate 21. In actual use, the second positioning plate 21 and the first limiting sleeve 22 are kept in a fixed state as a whole, and the second limiting sleeve 31 is rotatably arranged at the top of the first limiting sleeve 22, wherein, when used in the state where the blade is in an arc shape, the rubber stirring rod can be used to 38 As the outer wall of the blade moves and drives the reciprocating threaded screw 32 to deflect as a whole, a pushing force is generated on the second limiting sleeve 31, so that the second limiting sleeve 31 rotates as a whole on the top of the first limiting sleeve 22, and the impeller is sleeved on the outer walls of multiple limiting clamps 23 and supported on the top of the second positioning plate 21. By driving the multiple limiting clamps 23 to slide on the top of the second positioning plate 21, the distance between the multiple limiting clamps 23 changes until the multiple limiting clamps 23 are all in contact with the inner wall of the impeller, thereby completing the preliminary installation and limiting work of the impeller as a whole.

[0038] Combination Figure 1-2As shown, the electroplating mechanism 1 includes a liquid storage tank 101 arranged at the bottom of the second positioning plate 21, a plurality of first positioning plates 102 are fixedly installed at the bottom of the liquid storage tank 101, a positioning block 103 is fixedly installed at the top center position of the plurality of first positioning plates 102, and a plurality of first positioning grooves 104 are opened at the top of the plurality of first positioning plates 102, a guide block 28 is fixedly installed at the bottom of the second positioning plate 21, a second positioning groove 29 that matches the positioning block 103 is opened at the bottom of the guide block 28, and a plurality of positioning rods 210 are fixedly installed at the bottom of the second positioning plate 21, and the plurality of positioning rods 210 are inserted into the inner cavity of the first positioning groove 104, and the positioning block 10 3 is inserted into the inner cavity of the second positioning groove 29. The purpose of such arrangement is that after the impeller is installed on the second positioning plate 21 and the first limiting sleeve 22, the positioning rods 210 are inserted into the inner cavity of the first positioning groove 104, and the positioning block 103 is inserted into the inner cavity of the second positioning groove 29, so as to complete the installation and limiting work of each impeller as a whole and the liquid storage tank 101, so that each impeller is kept in a limited state and placed in the inner cavity of the liquid storage tank 101 during electroplating, avoiding the problem that the impeller as a whole is tilted when the electrolyte is stirred and in contact with the blades, causing multiple impellers to be knocked down in the inner cavity of the liquid storage tank 101 at the same time, making the subsequent removal of the impeller more convenient.

[0039] Further, see Figure 5 As shown, the interior of the first limiting sleeve 22 is set in a hollow state, and the interior of the first limiting sleeve 22 rotates according to the electric screw 24. The outer wall of the electric screw 24 is threadedly connected with multiple internal threaded sleeves 25. The outer wall of the first limiting sleeve 22 is provided with multiple guide slots 26 that are set in a through shape. The inner cavities of the multiple guide slots 26 are slidably installed with at least two first support brackets 27, and each first support bracket 27 is respectively arranged with the limiting clamping plate 23 and the internal threaded sleeve 25 in a mutually hinged state. In actual use, the internal threaded sleeve 25 can be moved up and down on its outer wall by rotating the electric screw 24, and then the first support bracket 27 is driven to deflect to push and pull the limiting clamping plate 23 to slide on the top of the second positioning plate 21, so as to adjust the distance between the limiting clamping plate 23 and the outer wall of the first limiting sleeve 22, so as to be suitable for limiting the impellers with different inner diameters, so that the impellers can be kept in a relatively static state during the electroplating process.

[0040] Among them, each first support bracket 27 is set in an inclined state under normal conditions, and the two first support brackets 27 set inside each guide slot 26 are set in a symmetrical state about the horizontal center line of the guide slot 26. The purpose of such a setting is that when the electric screw 24 is started to rotate to cause the internal threaded sleeve 25 to move, the first support bracket 27 and the side connected to the internal threaded sleeve 25 can be synchronously driven to move synchronously, thereby changing the inclination angle of the first support bracket 27, so that when the inclination slope of the first support bracket 27 gradually becomes steeper, the multiple limit clamps 23 can be synchronously close to the first limit The outer wall of the sleeve 22 is suitable for limiting the impeller with a smaller inner diameter. When the slope of the first support bracket 27 is gradually reduced, the multiple limiting clamps 23 can be synchronously moved away from the outer wall of the first limiting sleeve 22, so that it is suitable for limiting the impeller with a larger inner diameter. By making the two first support brackets 27 symmetrical about the horizontal center line of the guide groove 26, the limiting clamps 23 can be subjected to uniform force as a whole, and then can be stably moved on the top of the second positioning plate 21 and the outer wall of the first limiting sleeve 22, and the inner wall of the impeller is supported more stably and the force is balanced.
