Description

Technical Field

[0001] This utility model relates to the field of electroplating machine technology, and in particular to a robotic electroplating machine. Background Technology

[0002] A spin plating machine is a special piece of equipment used in electroplating processes. It mainly uses centrifugal force to improve the uniformity of the coating, reduce waste of plating solution, and increase electroplating efficiency. Unlike traditional rack plating or barrel plating, a spin plating machine uses high-speed rotation (or oscillation) to make the workpiece move in the plating solution. It uses centrifugal force to make the plating solution adhere more evenly to the surface of the workpiece, while shaking off excess plating solution, thereby reducing material loss and improving the quality of the coating.

[0003] However, the existing centrifugal electroplating machine has a single motion mode, which cannot ensure full coverage of the coating on complex workpieces (such as inner holes and grooves). It is easy to have problems such as no coating in some areas or too thin coating. Moreover, the recovery of the plating solution depends entirely on gravity natural reflux, which is very slow and the recovery rate is usually less than 90%. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a robotic arm-type spin plating machine, which solves the technical problems of the single motion mode and low plating solution recovery rate of the existing centrifugal spin plating machine. It has the advantages of breaking through the limitation of the single rotation mode of the traditional spin plating machine and effectively improving the plating solution recovery efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a robotic arm-type electroplating machine, including an electroplating tank, wherein the electroplating tank is equipped with a mechanical electroplating mechanism for batch electroplating, and a plating solution recovery mechanism is coaxially fixedly installed at the upper end of the electroplating tank. A workpiece body is placed on the mechanical electroplating mechanism. During the electroplating process, the workpiece body will enter the interior of the electroplating tank under the action of the mechanical electroplating mechanism. Subsequently, the mechanical electroplating mechanism will cause the workpiece body to rotate, thereby completing the electroplating process. The mechanical electroplating mechanism includes a lifting vertical rod fixedly installed inside the electroplating tank. A rotating platform is movably installed at the upper end of the lifting vertical rod. Several mounting rods are evenly spaced on the rotating platform. Workpiece clamps are movably installed on the mounting rods. A replenishment pipe for replenishing electroplating solution is provided at the lower end of the electroplating tank. When the rotating platform rotates, it will cause multiple mounting rods to rotate synchronously, thereby causing the workpiece body to rotate.

[0006] Preferably, the plating solution recovery mechanism includes a recovery inclined tube fixedly connected coaxially to the electroplating tank. The inner wall of the recovery inclined tube is provided with a plurality of side wall inclined grooves. The inner wall of the electroplating tank is provided with a return liquid hole, which is connected to the side wall inclined grooves. After the workpiece leaves the liquid surface, the excess plating solution will be thrown into the interior of the side wall inclined grooves under the action of centrifugal force, and then return to the interior of the electroplating tank through the return liquid hole.

[0007] Preferably, the lifting rod is equipped with a drive motor for driving the rotating platform. During the electroplating operation, the drive motor will cause the rotating platform to rotate at a constant speed.

[0008] Preferably, the mounting rod is equipped with a micro motor for driving the workpiece fixture to rotate. During the electroplating operation, the micro motor will cause the workpiece fixture to rotate periodically.

[0009] Preferably, an annular boss is fixedly installed inside the recovery inclined tube, and a plurality of exhaust holes are equally spaced on the annular boss. An air inlet is fixedly installed on the outside of the recovery inclined tube, and the exhaust holes are directly above the inclined groove on the side wall.

[0010] Preferably, the annular boss is hollow inside, and the air inlet is connected to the interior of the annular boss. After the inert gas enters the annular boss from the air inlet, it will be ejected downward through multiple exhaust holes.

[0011] By employing the above technical solution, this utility model provides a robotic arm-type spin plating machine, which has at least the following beneficial effects:

[0012] 1. This utility model, by setting up a mechanical electroplating mechanism, uses a three-linkage mechanism of "revolution-rotation-lifting" to make the workpiece form a spatial spiral motion trajectory in the plating solution, breaking through the limitation of the single rotation mode of traditional electroplating machines. It can largely eliminate electroplating blind spots and increase the coating coverage of the inner wall of deep hole parts (hole diameter / depth ratio ≥1:5) from 60% to 98%.

[0013] 2. This utility model sets up a plating solution recovery mechanism and adopts an original "gas-liquid dual-drive recovery" mechanism to realize the dynamic circulation of plating solution. This not only effectively improves the recovery efficiency of plating solution, but also the air curtain barrier of the annular boss can isolate oxygen and prevent plating solution deterioration problems such as oxidation of ferrous iron to a certain extent.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Existing centrifugal electroplating machines have a single motion mode, which cannot ensure complete coating coverage of complex workpieces (such as internal holes and grooves). This easily leads to problems such as uncoated areas or excessively thin coatings. Furthermore, the recovery of the plating solution relies entirely on gravity-driven natural reflux, which is very slow, with a recovery rate typically below 90%. To address this technical deficiency in existing technologies, such as... Figures 1-4 As shown, this embodiment proposes a robotic arm-type electroplating machine. Through a three-linkage mechanism of "revolution-rotation-lifting", the workpiece forms a spatial spiral motion trajectory in the plating solution. The electroplating tank 1 is equipped with a mechanical electroplating mechanism 2 for batch electroplating. A plating solution recovery mechanism 3 is coaxially fixed at the upper end of the electroplating tank 1. The workpiece body 4 is placed on the mechanical electroplating mechanism 2. During the electroplating process, the workpiece body 4 will enter the interior of the electroplating tank 1 under the action of the mechanical electroplating mechanism 2. Subsequently, the mechanical electroplating mechanism 2 will make the workpiece body 4 rotate, thereby completing the electroplating process.

[0023] Specifically, the mechanical electroplating mechanism 2 includes a lifting vertical rod 201 fixedly installed inside the electroplating tank 1. A rotating platform 202 is movably mounted on the upper end of the lifting vertical rod 201. A drive motor for driving the rotating platform 202 is installed inside the lifting vertical rod 201. During electroplating, the drive motor causes the rotating platform 202 to rotate at a constant speed. Several mounting rods 203 are evenly spaced on the rotating platform 202. A workpiece clamp 204 is movably mounted on the mounting rods 203. A micro motor for driving the workpiece clamp 204 to rotate is installed inside the mounting rods 203. During electroplating, the micro motor causes the workpiece clamp 204 to rotate periodically. A replenishment pipe 205 for replenishing electroplating solution is provided at the lower end of the electroplating tank 1. When the rotating platform 202 rotates, it causes multiple mounting rods 203 to rotate synchronously, thereby causing the workpiece body 4 to be in a rotating state.

[0024] Specifically, the plating solution recovery mechanism 3 includes a recovery inclined tube 301 coaxially and fixedly connected to the electroplating tank 1. Several side wall inclined grooves 302 are formed on the inner wall of the recovery inclined tube 301. A return liquid hole 303 is formed on the inner wall of the electroplating tank 1, communicating with the side wall inclined grooves 302. After the workpiece leaves the liquid surface, excess plating solution is thrown into the side wall inclined grooves 302 under centrifugal force, and then returns to the electroplating tank 1 through the return liquid hole 303. An annular boss 304 is fixedly installed inside 301. Several exhaust holes 305 are equally spaced on the annular boss 304. An air inlet 306 is fixedly installed on the outside of the recovery inclined pipe 301. The exhaust holes 305 are directly above the inclined groove 302 on the side wall. The annular boss 304 is hollow inside. The air inlet 306 is connected to the inside of the annular boss 304. After the inert gas enters the annular boss 304 from the air inlet 306, it will be sprayed downward through the multiple exhaust holes 305.

[0025] As can be seen from the above, when electroplating workpieces using this electroplating machine, the operator first places multiple workpiece bodies 4 onto the workpiece fixture 204 in sequence. At this time, the workpiece fixture 204 will limit and fix the workpiece bodies 4 under the elastic force of the spring.

[0026] Next, the rotating platform 202 will move vertically downward under the action of the lifting rod 201, thereby moving the workpiece body 4 into the electroplating solution. At the same time, the rotating platform 202 will rotate under the action of the drive motor, thereby causing the workpiece body 4 to revolve around the lifting rod 201.

[0027] Furthermore, the workpiece fixture 204 will rotate intermittently under the action of a micro motor. When the workpiece fixture 204 rotates, the workpiece body 4 will rotate, thereby making the plating solution adhere more evenly to the surface of the workpiece.

[0028] After a certain period of time, the rotating platform 202 will move upward a certain distance under the action of the lifting rod 201, thereby removing the workpiece body 4 from the plating solution. Next, as the rotating platform 202 and the workpiece clamp 204 continue to rotate, the excess plating solution on the surface of the workpiece body 4 will be thrown out. The thrown-out plating solution will enter the interior of the side wall inclined groove 302 and finally flow back into the interior of the electroplating tank 1 through the return liquid hole 303.

[0029] Moreover, the inert gas enters the interior of the annular boss 304 through the air inlet 306 and is ejected downward through multiple exhaust holes 305. After the gas is ejected, it will accelerate the liquid flow in the side wall inclined groove 302, so that the plating solution can quickly flow back into the interior of the electroplating tank 1, which can effectively reduce material loss.

[0030] This embodiment, by setting up a mechanical electroplating mechanism 2, uses a three-linkage mechanism of "revolution-rotation-lifting" to make the workpiece form a spatial spiral motion trajectory in the plating solution, breaking through the limitations of the single rotation mode of traditional electroplating machines. This can largely eliminate electroplating blind spots and increase the coating coverage of the inner wall of deep hole parts (hole diameter / depth ratio ≥ 1:5) from 60% to 98%. Moreover, this embodiment, by setting up a plating solution recovery mechanism 3, adopts an original "gas-liquid dual-drive recovery" mechanism to achieve dynamic circulation of the plating solution. This not only effectively improves the recovery efficiency of the plating solution, but also the air curtain barrier of the annular boss 304 can isolate oxygen and prevent plating solution deterioration problems such as oxidation of ferrous iron to a certain extent.

[0031] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
