[0002] Since electroplating liquids are highly corrosive, the materials of the stirring device must be able to withstand the corrosion of electroplating solutions. Common materials include plastics, special alloys, or metals with corrosion-resistant coatings. The solutions in the electroplating tank need to be evenly mixed to ensure the uniformity and quality of the plating layer.

However, the existing electroplating stirring equipment has poor stirring effect, a single stirring direction, and requires a long time of stirring to achieve high quality. The mixing efficiency is low. If the mixing is not sufficient, it will cause the precipitation of solution dregs, and for workpieces with complex shapes, stripes, spots, and other defects are likely to appear.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0043] As Figures 1-3 shown, an electroplating tank stirring device includes: an electroplating tank 1, a control motor 2, a main driving wheel 3, a transmission belt 4, a lifting mechanism 5, a mounting member 6, a connecting frame 7, a stirring motor 8, a transmission rod 9, a fixed housing 10, a socket housing 11, a deflecting rod 12, a first rotating blade 13, and a second rotating blade 14. The electroplating tank 1 is erected on the ground. The control motor 2 is installed on one side edge of the electroplating tank 1. This layout helps to ensure the stability of the electroplating tank 1, and at the same time, the position of the control motor 2 is beneficial to driving the movement of the electroplating tank 1. The control motor 2 is erected on one side edge of the electroplating tank 1, the main driving wheel 3 is installed at the output end of the control motor 2, and the transmission belt 4 is sleeved on the main driving wheel 3. This design can effectively transmit power to realize the lifting or lowering of the mounting member 6, and thus facilitate the lifting of the stirring device. There are two groups of lifting mechanisms 5, and the two groups of lifting mechanisms 5 are respectively installed on the two side edges at the top of the electroplating tank 1.

[0044] At least two mounting members 6 are respectively installed on the top of the lifting mechanism 5. Both ends of the connecting frame 7 are connected to the two mounting members 6. The output end of the stirring motor 8 longitudinally penetrates through the connecting frame 7. The transmission rod 9 is installed at the output end of the stirring motor 8. The fixed housing 10 is installed on the bottom surface of the connecting frame 7. The top of the socket housing 11 is connected to the bottom of the fixed housing 10. The top end of the deflecting rod 12 is movably installed at the bottom of the socket housing 11, and the bottom end of the transmission rod 9 penetrates through the socket housing 11. The first rotating blade 13 is arranged at the bottom of the transmission rod 9. The first rotating blade 13 is located above the second rotating blade 14. The second rotating blade 14 is arranged at the bottom of the deflecting rod 12.

[0045] In this embodiment, as Figures 1-2As shown in the figure, the lifting mechanism 5 further includes: a screw rod 51 is installed on the edge of the top of the electroplating tank 1, a driving roller 52 is sleeved on one end of the screw rod 51, one end of a transmission belt 4 is sleeved on the driving roller 52, a sliding rod 53 is installed inside the mounting member 6, one end of a first support rod 54 is movably connected to the screw rod 51, the other end of the first support rod 54 is movably connected to the sliding rod 53, one end of a second support rod 55 is movably installed at one end of the electroplating tank 1, and the other end of the second support rod 55 is movably connected to the rod body of the sliding rod 53. The driving roller 52 drives the screw rod 51 to rotate axially. Here, taking the downward movement as an example, when the screw rod 51 rotates axially, the connecting end of the first support rod 54 and the screw rod 51 moves axially towards the direction of the belt, the inclination angle of the first support rod 54 decreases, and at the same time, the sliding rod 53 at the top of the first support rod 54 is gradually pulled down. Due to the downward movement of the sliding rod 53, the socket joint of the second support rod 55 and the sliding rod 53 slides axially on the sliding rod 53, and the inclination angle of the second support rod 55 decreases correspondingly to that of the first support rod 54. The sliding rod 53 drives the mounting member 6, and the mounting member 6 drives the connecting frame 7 to descend. Finally, the connecting frame 7 drives the stirring mechanism to descend until it is immersed in the solution. The lifting mechanism 5 enables the mounting member 6 to drive the stirring device to move up and down. This design can stably control the height adjustment of the stirring device, so that the device can adapt to the depths of different electroplating solutions and the heights of the workpieces in the tank.

[0046] Preferably, in order to achieve the coaxial reverse rotation effect of the first rotating blade 13 and the second rotating blade 14, a driving gear 15 is sleeved on the rod body of the transmission rod 9. The top of the transmission rod 9 is located inside the fixed housing 10. The top of the reversing rod 12 is located inside the socket housing 11. A reversing gear 16 is longitudinally installed on the inner wall of the socket housing 11. The reversing gear 16 meshes with the driving gear 15. A driven gear 17 is installed on the top of the reversing rod 12. The driven gear 17 meshes with the reversing gear 16. The coaxial reverse rotation component realizes forward and reverse rotation through the cooperation of the driving gear 15 and the reversing gear 16. When the stirring motor 8 is started, the driving gear 15 drives the reversing gear 16, and the reversing gear 16 rotates the driven gear 17 in the opposite direction. This design will ultimately drive the two stirring blades to rotate in opposite directions, forming two opposite air vortices and shear forces, thereby achieving a more effective stirring effect. The coaxial reverse rotation simplifies the mechanical design, reduces the required space, and improves the overall efficiency of the system. In addition, it helps to reduce wear, because the movement of the stirring blades in opposite directions can balance each other's stresses and extend the service life of the device.

[0047] It should be noted that the present utility model is an electroplating tank stirring device. When in use, the control motor 2 is started. The output end of the motor rotates to drive the transmission belt 4. The transmission belt 4 rotates to drive two sets of lifting mechanisms 5. The transmission roller 52 rotates to drive the screw rod 51. The axial rotation of the screw rod 51 causes one end of the first support rod 54 to axially move. The axial movement of one end of the first support rod 54 drives the other end to push or pull the inner sliding rod 53 of the mounting member 6. Furthermore, the mounting member 6 is driven to rise or fall through the inner sliding rod 53. The top of the second support rod 55 will axially slide on the sliding rod 53 driven by the first support rod 54, and the second support rod 55 will pivot at its bottom as the center to play a supporting role for the lifting of the mounting member 6. When the first rotating blade 13 and the second rotating blade 14 are immersed in the solution, the stirring motor 8 is started. The output end of the stirring motor 8 rotates to drive the transmission rod 9. The transmission rod 9 rotates to drive the driving gear 15 on the rod body to rotate. The driving gear 15 drives the reversing gear 16 to rotate. The reversing gear 16 rotates the driven gear 17. The driven gear 17 will be rotated by the reversing gear 16 in the opposite direction. The transmission rod 9 rotates to drive the first rotating blade 13 at the bottom to start stirring. The rotation of the driven gear 17 will drive the reversing rod 12. The rotation of the reversing rod 12 will drive the second rotating blade 14 at the bottom. The second rotating blade 14 will rotate in the opposite direction to the first rotating blade 13, forming two opposite air vortices and shear forces, making the electroplating solution stirred more evenly.

[0048] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
