Description

Technical Field

[0001] This invention relates to the field of electroplating technology, specifically to a fully automatic rotary electroplating machine. Background Technology

[0002] Electroplating, also known as electrochemical deposition, is a surface treatment technology that uses the principle of electrolysis to deposit a uniform, dense, and well-bonded metal or alloy coating on the surface of a metal or non-metal substrate. Electroplating machines are required when electroplating products.

[0003] In current disc-type electroplating equipment, the electroplating disc and workpiece cannot achieve automatic and stable controlled rotation during operation. The plating solution cannot form a uniformly flowing liquid film on the workpiece surface, which not only causes uneven coating thickness and a decrease in yield, but also requires extending the electroplating time to compensate for the coating thickness, resulting in a significant reduction in overall electroplating efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic rotary electroplating machine to solve the problems mentioned in the background art. In the current electroplating disc type electroplating equipment, the electroplating disc and workpiece cannot achieve automatic and stable controlled rotation during operation, and the plating solution cannot form a uniformly flowing liquid film on the surface of the workpiece. This results in uneven plating thickness, reduced yield, and a significant reduction in overall electroplating efficiency due to the need to extend the electroplating time to compensate for the plating thickness.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic rotary electroplating machine, comprising a frame and a rotating assembly. A moving assembly is mounted on the upper part of the frame, and a robotic arm is connected to the output end of the moving assembly. A loading and unloading platform is mounted in the middle of one end of the frame, and an electroplating tray is embedded in the top of the loading and unloading platform. A first station platform is rotatably connected to the middle of the frame, and a second station platform is provided on one side of the first station platform. The rotating assembly is located at the bottom of the first and second station platforms, and includes a rotary motor and a synchronous pulley assembly. A rotary motor is mounted on the lower part of the frame, and a synchronous pulley assembly is connected to the output end of the rotary motor. A drainer is mounted on the lower part of the first and second station platforms, and a conductive cup is connected to the bottom of the drainer. A liquid-holding tank is mounted on the lower part of the frame, and a liquid supply mechanism is connected to the top of the liquid-holding tank. A cover-opening assembly is provided on one side of the middle of the frame, and an anode assembly is mounted on the other side of the middle of the frame.

[0006] Furthermore, the first workstation platform and the second workstation platform have the same structure, and the first workstation platform and the second workstation platform are respectively fixedly connected to the synchronous pulleys on the corresponding synchronous pulley sets.

[0007] Furthermore, the moving component includes a guide rail frame, a running trolley, and a linear module. The guide rail frame is mounted on the upper part of the frame, and the running trolley is mounted on the upper part of the guide rail frame. The linear module is fixedly connected to the bottom of the running trolley.

[0008] Furthermore, the cover opening assembly includes a lifting cylinder, a connecting plate, a swing arm, a rotating shaft seat, and a cover plate. The upper end of the lifting cylinder is rotatably connected to the connecting plate, and the upper end of the connecting plate is rotatably connected to the swing arm. One end of the swing arm is rotatably connected to the rotating shaft seat, and the other end of the swing arm is fixedly connected to the cover plate.

[0009] Furthermore, the lifting cylinder is fixedly connected to the frame, and the frame is fixedly connected to the rotating shaft seat.

[0010] Furthermore, the anode assembly includes a rotary pressing cylinder, a pressing arm, an anode rod, and a sealing cover. The upper end of the rotary pressing cylinder is connected to the pressing arm, and an anode rod is mounted on one end of the pressing arm. A sealing cover is provided on the upper part of the anode rod.

[0011] Furthermore, the rotary pressing cylinder is fixedly connected to the frame, and two rotary pressing cylinders are provided.

[0012] Furthermore, a through hole is provided at the top center of the cover plate, and the inner diameter of the through hole at the top of the cover plate is smaller than the diameter of the sealing cover.

[0013] Furthermore, the trolley moves horizontally along the guide rail, and the linear module is used to drive the robotic arm to lift and lower, so as to grasp and transfer the electroplating tray.

[0014] Furthermore, the liquid supply mechanism is used to transport the plating solution in the liquid tank to the first station platform and the second station platform, and the liquid drainer is used to recover the plating solution after electroplating into the liquid tank, so as to realize the recycling of the plating solution.

[0015] This invention provides a fully automatic rotary electroplating machine, which has the following advantages: 1. This invention, through the setting of a rotating component, allows the rotating motor to drive the synchronous pulley group to rotate during the electroplating process, thereby driving the first or second station platform to rotate, which in turn controls the rotation of the electroplating tray placed above. At the same time, the current from the rectifier is stably conducted to the electroplating tray through the conductive cup. After the anode rod is inserted into the plating solution in the electroplating tray, the periodic forward and reverse rotation of the electroplating tray can drive the plating solution to form a dynamic liquid flow on the surface of the workpiece, so that the workpiece and the plating solution can fully contact each other, avoiding the difference in plating thickness caused by local plating solution concentration differences and uneven ion distribution, which greatly improves the uniformity of the plating layer and the yield. At the same time, the dynamic liquid flow can accelerate the electroplating reaction rate, eliminating the need to extend the electroplating time to compensate for the plating thickness, effectively shortening the single batch electroplating cycle, and significantly improving the efficiency of electroplating operations. 2. By setting up the cover opening component, after the electroplating tray is placed on the first or second workstation platform, the lifting cylinder can be activated, which drives the swing arm to rotate around the rotating shaft of the rotating shaft seat through the connecting plate. This causes the cover plate to form a sealed shield to protect the outside of the electroplating tray. This structure can effectively prevent the internal plating solution from splashing and spilling during the rotation of the electroplating tray, thus preventing the plating solution from contaminating the equipment and working environment and reducing plating solution loss. At the same time, when the rotating pressing cylinder drives the anode rod to be inserted from the through hole at the top of the cover plate, the sealing cover can simultaneously block and seal the top opening of the cover plate, further improving the protection effect and reducing the risk of plating solution evaporation and external impurities entering the plating solution. This reduces plating solution loss, prevents impurities from affecting the plating quality, and improves the safety of the operation process. 3. This invention, through the setting of moving components and robotic arms, can automatically transfer the electroplating trays placed on the loading and unloading platform to the first station platform, achieving precise docking between the bottom of the electroplating tray and the top interface of the first station platform. After docking, the liquid supply mechanism can stably deliver the plating solution in the liquid tank to the first station platform. After electroplating, the liquid drainer can recover the plating solution back into the liquid tank, realizing the recycling of the plating solution. Subsequently, the moving components and robotic arms can transfer the electroplating trays to the second station platform for secondary electroplating. After completion, the electroplating trays are sent back to the loading and unloading platform, realizing the fully automated operation of loading, transfer, electroplating, liquid draining, and unloading. This structure reduces manual intervention and avoids direct contact between operators and corrosive plating solutions, improving operational safety. Through the dual-station rotating platform and automatic transfer robotic arm, continuous operation of the electroplating process is achieved. The combination of rotation drive and sealing protection structure effectively improves the uniformity of the plating layer and reduces plating solution loss. The overall structure layout is reasonable, the operation is stable and reliable, and it is suitable for automated electroplating processing of various small workpieces. Attached Figure Description

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0019] like Figures 1 to 3As shown, a fully automatic rotary electroplating machine includes a frame 1 and a rotating assembly 8. A moving assembly 2 is mounted on the upper part of the frame 1, and a robot arm 3 is connected to the output end of the moving assembly 2. The moving assembly 2 includes a guide rail frame 201, a trolley 202, and a linear module 203. The guide rail frame 201 is mounted on the upper part of the frame 1, and the trolley 202 is mounted on the upper part of the guide rail frame 201. The linear module 203 is fixedly connected to the bottom of the trolley 202. The trolley 202 moves on the guide rail frame 201 to control the horizontal position of the robot arm 3, while the linear module 203... The gripping height of the robotic arm 3 can be controlled. A loading / unloading platform 4 is installed at the middle of one end of the frame 1, and an electroplating tray 5 is embedded in the top of the loading / unloading platform 4. A first station platform 6 is rotatably connected to the middle of the frame 1, and a second station platform 7 is provided on one side of the first station platform 6. The multiple stations can meet the requirements of multi-layer electroplating. A rotating assembly 8 is located at the bottom of the first station platform 6 and the second station platform 7, and the rotating assembly 8 includes a rotary motor 801 and a synchronous pulley set 802. The rotary motor 801 is installed at the lower part of the frame 1, and the output end of the rotary motor 801 is connected to… A synchronous pulley set 802 is connected to the workpiece. The first station platform 6 and the second station platform 7 have the same structure, and the first station platform 6 and the second station platform 7 are respectively fixedly connected to the synchronous pulleys on the corresponding synchronous pulley set 802. The rotary motor 801 drives the synchronous pulley set 802 to rotate, which in turn drives the first station platform 6 or the second station platform 7 to rotate, thereby controlling the rotation of the electroplating tray 5 placed above. The periodic forward and reverse rotation of the electroplating tray 5 can drive the plating solution to form a dynamic liquid flow on the surface of the workpiece, so that the workpiece and the plating solution can fully contact each other and avoid the problems caused by local concentration differences of plating solution and uneven ion distribution. The coating thickness difference is reduced, which greatly improves the coating uniformity and yield. The lower part of the first station platform 6 and the second station platform 7 is equipped with a drain device 9, and the bottom of the drain device 9 is connected to a conductive cup 10. The current of the rectifier will be stably conducted to the electroplating tray 5 through the conductive cup 10. The lower part of the frame 1 is equipped with a liquid tank 11, and the top of the liquid tank 11 is connected to a liquid supply mechanism 12. The liquid supply mechanism 12 can stably transport the plating solution in the liquid tank 11 to the first station platform 6. After the electroplating is completed, the drain device 9 can recover the plating solution into the liquid tank 11, realizing the recycling of the plating solution.

[0020] like Figure 4 and Figure 5As shown, a cover opening assembly 13 is provided on one side of the middle of the frame 1, and an anode assembly 14 is arranged on the other side of the middle of the frame 1. The cover opening assembly 13 includes a lifting cylinder 1301, a connecting plate 1302, a swing arm 1303, a rotating shaft seat 1304, and a cover plate 1305. The upper end of the lifting cylinder 1301 is rotatably connected to the connecting plate 1302, and the upper end of the connecting plate 1302 is rotatably connected to the swing arm 1303. One end of the swing arm 1303 rotates... The swing arm 1303 is connected to a rotating shaft seat 1304, and a cover plate 1305 is fixedly connected to the other end of the swing arm 1303. A lifting cylinder 1301 is fixedly connected to the frame 1, and the frame 1 is fixedly connected to the rotating shaft seat 1304. Activating the lifting cylinder 1301 causes it to drive the swing arm 1303 to rotate around the rotating shaft of the rotating shaft seat 1304 via the connecting plate 1302. This causes the cover plate 1305 to form a sealed shield protecting the outer side of the electroplating tray 5. This structure can effectively prevent… During the rotation of the electroplating tray 5, the internal plating solution splashes and spills, preventing the plating solution from contaminating the equipment and working environment. The anode assembly 14 includes a rotating pressing cylinder 1401, a pressing arm 1402, an anode rod 1403, and a sealing cover 1404. The upper end of the rotating pressing cylinder 1401 is connected to the pressing arm 1402, and one end of the pressing arm 1402 is equipped with the anode rod 1403. The sealing cover 1404 is provided on the upper part of the anode rod 1403. The rotating pressing cylinder 1401 is fixedly connected to the frame 1, and there are two rotating pressing cylinders 1401. The rotating pressing cylinder 1401 can drive the anode rod 1403 to be inserted through the top through hole of the cover plate 1305. The top center of the cover plate 1305 is provided with a through hole, and the inner diameter of the top through hole of the cover plate 1305 is smaller than the diameter of the sealing cover 1404. The sealing cover 1404 can block and seal the top opening of the cover plate 1305, further improving the protection effect.

[0021] In summary, when using this fully automatic rotary electroplating machine, firstly, the trolley 202 moves on the guide rail frame 201, and the robot arm 3 is controlled to grab and transfer the electroplating tray 5 placed on the loading and unloading platform 4 to the first station platform 6, achieving precise docking between the bottom of the electroplating tray 5 and the top interface of the first station platform 6. After docking, the liquid supply mechanism 12 can stably deliver the plating solution in the liquid tank 11 to the first station platform 6. Then, the lifting cylinder 1301 is activated, which drives the swing arm 1303 to rotate around the axis via the connecting plate 1302. The rotating shaft of seat 1304 rotates, causing cover plate 1305 to form a sealed shield protecting the outside of electroplating tray 5. This structure effectively prevents splashing and spillage of the plating solution inside the electroplating tray 5 during rotation. Subsequently, when the rotating pressing cylinder 1401 drives the anode rod 1403 to be inserted through the top through hole of cover plate 1305, the sealing cover 1404 simultaneously blocks and seals the top opening of cover plate 1305, further enhancing the protective effect. Then, the current from the rectifier is stably conducted to the electroplating tray 5 through conductive cup 10, protecting the internal components. During electroplating, the rotary motor 801 drives the synchronous pulley group 802 to rotate, which in turn drives the first station platform 6 to rotate. This, in turn, controls the rotation of the electroplating tray 5 placed above it. Through the periodic forward and reverse rotation of the electroplating tray 5, the plating solution forms a dynamic liquid flow on the surface of the workpiece, ensuring full contact between the workpiece and the plating solution. This significantly improves the uniformity of the plating layer and the yield rate. At the same time, the dynamic liquid flow can accelerate the electroplating reaction rate. Finally, after electroplating is completed, the drain device 9 can recover the plating solution into the liquid collection tank 11, realizing the recycling of the plating solution. Simultaneously, the anode assembly 14 and the cover opening assembly 13 are opened and reset in sequence. The moving assembly 2 and the robot arm 3 then transfer the electroplating tray 5 to the second station platform 7 for secondary electroplating. After completion, the electroplating tray 5 is sent back to the loading and unloading platform 4, realizing the fully automated operation of loading, transfer, electroplating, draining and unloading. During the electroplating process, the first station platform 6 and the second station platform 7 can be independently rotated according to the process requirements to meet the processing requirements of different workpieces and different coatings, and improve the versatility and adaptability of the equipment.
