[0019] Specifically, after the solution is injected into the box body 4 through the liquid adding hopper 5, according to the required solution concentration, the first motor 819 is started. The first motor 819 drives the bidirectional lead screw 817 to rotate, so that the movable block 820 moves on the bidirectional lead screw 817, and then the push-pull rod 821 drives the movable plate 815 to move up and down in the liquid storage tank 808, changing the volume of the solution flowing into the liquid storage tank 808 from the box body 4. The second motor 829 is started. The second motor 829 drives the semi-gear 830 to rotate, so that the toothed ring 828 meshing with the coil spring 803 rotates 180 degrees, and the accommodating cylinder 804 drives the liquid measuring column 807 to rotate to the position of the bottom flow-through groove 806 on the sealing block 801, pouring the solution in the liquid storage tank 808 into the liquid outlet pipe 10. The solution flowing out of the liquid outlet pipe 10 falls onto the liquid guiding plate 802 and enters the mixing barrel 7 under the guidance of the liquid guiding plate 802. The second motor 829 is started again. The second motor 829 drives the semi-gear 830 to rotate 180 degrees again, and the accommodating cylinder 804 drives the liquid measuring column 807 to rotate back to its original position, waiting for the next solution injection.

[0020] In a specific application scenario, the quantitative addition module 8 is mainly applicable to the quantitative addition link in the quantitative addition process. That is, the quantitative addition module 8 can use the bidirectional lead screw 817 and the movable plate 815 to quickly and conveniently control the volume of the solution injected into the mixing barrel 7 each time, so that the device can accurately and effectively control the concentration of the configured chemical solution, avoiding the situation of adding other solutions for correction due to excessive or insufficient solution injection, reducing the waste of the solution, and lowering the cost.

[0021] Refer to Figure 7 and Figure 8, in a preferred embodiment, a stabilizing frame 901 is bolted to the upper side of the bearing platform plate 6. The inner wall of the stabilizing frame 901 is slidably connected to the outside of the mixing barrel 7. The inner wall of the barrel body 1 is bolted with a mounting ring 902, and a plurality of connecting seats 904 evenly distributed at equal circumferential intervals are bolted to the upper side of the mounting ring 902; round rods 903 are slidably connected to the plurality of connecting seats 904. The sides of the round rods 903 away from the connecting seats 904 are bolted to the outside of the bearing platform plate 6, and springs two 905 are wound around the outside of the round rods 903. One ends of the springs two 905 are bolted to the outside of the connecting seats 904 on the same side, and the other ends are bolted to the outside of the bearing platform plate 6; a support frame 906 is bolted to the bottom inner wall of the barrel body 1. A hole slot is formed in the upper side of the support frame 906. A short rod is rotatably connected to the inner wall of the hole slot through a bearing. The upper side of the short rod is bolted to the bottom of a cam 907. One end of the cam 907 away from the short rod contacts the inner wall of an elliptical ring 908. The upper side of the elliptical ring 908 is bolted to the bottom of the bearing platform plate 6, and a motor three 909 is bolted to the bottom inner wall of the barrel body 1. The output end of the motor three 909 is connected to the bottom of the short rod through a coupling.

[0022] Specifically, after the solution in the mixing barrel 7 is put in place, start the motor three 909. The motor three 909 drives the cam 907 to rotate. When the cam 907 rotates to a narrower area on the elliptical ring 908, the cam 907 can push the elliptical ring 908, causing the elliptical ring 908 to drive the mixing barrel 7 on the bearing platform plate 6 to shake. Under the elastic force of the spring two 905, the mixing barrel 7 returns to its original position when the cam 907 moves to a wider area on the elliptical ring 908. Thus, as the cam 907 rotates, the mixing barrel 7 continuously shakes the solution, enabling the solution to undergo a mixing reaction.

[0023] In a specific application scenario, the non-contact stirring module 9 is mainly applicable to the non-contact stirring link in the non-contact stirring process. That is, the non-contact stirring module 9 uses the cam 907 and the elliptical ring 908 to enable the device to effectively promote the reaction of the mixed solution in the mixing barrel 7 through regular shaking without directly contacting the solution. On the premise of ensuring the sufficiency of the reaction, it avoids the situation of solution contamination caused by the contact between the stirring structure and the solution.

[0024] Working principle: When preparing the chemical treatment solution for hard disk aluminum materials, according to the required solution volume, the solution for preparation is injected into the box body 4 through the liquid adding hopper 5. After the solution is injected into the box body 4 through the liquid adding hopper 5, according to the required solution concentration, the first motor 819 is started. The first motor 819 drives the bidirectional lead screw 817 to rotate, so that the movable block 820 moves on the bidirectional lead screw 817, and then the push-pull rod 821 drives the movable plate 815 to move up and down in the liquid storage tank 808, changing the volume of the solution flowing into the liquid storage tank 808 in the box body 4. The second motor 829 is started. The second motor 829 drives the semi-gear 830 to rotate, so that the toothed ring 828 engaged with the coil spring 803 rotates 180 degrees, and the accommodating cylinder 804 drives the liquid measuring column 807 to rotate to the position of the bottom flow-through groove 806 on the sealing block 801, pouring the solution in the liquid storage tank 808 into the liquid outlet pipe 10. The solution flowing out of the liquid outlet pipe 10 falls onto the liquid guiding plate 802 and enters the mixing barrel 7 under the guidance of the liquid guiding plate 802. The second motor 829 is started again. The second motor 829 drives the semi-gear 830 to rotate 180 degrees again, and the accommodating cylinder 804 drives the liquid measuring column 807 to rotate back to its original position, waiting for the next solution delivery, so that different amounts of solution enter the mixing barrel 7. After the solution in the mixing barrel 7 is delivered, the third motor 909 is started. The third motor 909 drives the cam 907 to rotate. When the cam 907 rotates to the narrower area of the elliptical ring 908, the cam 907 can push the elliptical ring 908, so that the elliptical ring 908 drives the mixing barrel 7 on the bearing plate 6 to shake. Under the elastic force of the second spring 905, the mixing barrel 7 returns to its original position when the cam 907 moves to the wider area of the elliptical ring 908. Thus, with the rotation of the cam 907, the mixing barrel 7 continuously shakes the solution, causing the solution to mix and react, making the solution in the mixing barrel 7 fully mixed and reacted to form the required chemical treatment solution for hard disk aluminum materials. The closing door 3 is opened, and the mixing barrel 7 is taken out.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
