[0048] like Figure 1 and Figure 2 As shown, as an exemplary embodiment of the present application, a mixed liquid storage system includes:

[0049] Mixing tank 1, used for holding the mixed liquid;

[0050] A stirring device 2, used for stirring the mixed liquid, one end of the stirring device 2 extends into the mixing tank 1;

[0051] A driving device 3, for outputting rotational power, wherein the driving device 3 is located on one side of the liquid mixing tank 1;

[0052] The transmission device 4 is used to transmit the rotational power output by the driving device 3 to the stirring device 2 and drive the stirring device 2 to rotate. The transmission device 4 is connected between the stirring device 2 and the driving device 3.

[0053] With the above structure, the driving device 3 is arranged on one side of the mixing tank, which can effectively reduce the height of the mixing tank 1 in the polishing equipment, thereby providing convenience for the staff to add mixed liquid into the mixing tank 1.

[0054] Furthermore, to facilitate cleaning of the stirring device 2 by the staff, the stirring device 2 includes a rotating shaft 21 and a stirring rod 22. The rotating shaft 21 is arranged vertically on the outside of the mixing tank 1, and the stirring rod 22 is arranged along the rotation axis of the rotating shaft 21 and extends into the mixing tank 1. A connecting structure for detachable connection between the rotating shaft 21 and the stirring rod 22 is provided. When the staff needs to clean and maintain the stirring device 2, since the rotating shaft 21 is located outside the mixing tank 1 and does not come into contact with the mixed liquid, there is no need to clean it. Instead, they only need to disassemble the rotating shaft 21 and the stirring rod 22, and then remove the stirring rod 22 from the mixing tank 1 for cleaning, thereby making it easier for the staff to clean the stirring device 2.

[0055] Furthermore, the connection structure includes a protrusion 221 fixed on any one end of the rotating shaft 21 end and the stirring rod 22 end, a groove 211 opened at the other end of the rotating shaft 21 end and the stirring rod 22 end, and a connecting piece, the protrusion 221 and the groove 211 are plug-fitted, and a through hole is opened at the protrusion 221 and the groove 211, and the connecting piece passes through the through hole. The structure of the connecting piece is not limited, and it can be a pin or a bolt, and the bolt is threadedly connected to the through hole of the groove 211 through the through hole of the protrusion 221. It can be understood that as long as it can pass through the through hole of the groove 211 and extend into the through hole of the protrusion 221, so that the protrusion 221 is fixed in the groove 211, it can be used as a structure of the connecting piece.

[0056] like Figure 2 and Figure 3 As shown, further, as a preferred solution in the embodiment of the present application, in order to achieve the effect that the connecting member has good stability between the protrusion 221 and the groove 211 and is easy to disassemble; the groove 211 is opened at the end of the rotating shaft 21, the protrusion 221 is fixed to the end of the stirring rod 22, and the connecting member is preferably a rotating plunger 23.

[0057] The rotary plunger 23 comprises:

[0058] The fixing rod 231 has two ends that are interconnected, and one end of the fixing rod 231 is inserted into and fixed in the through-hole of the groove 211 where the rotating shaft 21 is located, while the other end is located outside the rotating shaft 21. The fixing method of the fixing rod 231 and the rotating shaft 21 is not limited. The fixing method can be: a threaded structure is machined on the inner wall of the through-hole of the fixing rod 231 and the rotating shaft 21, and the fixing rod 231 is connected and fixed to the rotating shaft 21 by a threaded connection; or it can be fixed by welding, gluing, interference fit, etc. The fixing rod 231 is preferably fixed to the rotating shaft 21 by a threaded connection, which has the advantages of simple and convenient installation, easy disassembly and replacement, good stability and not easy to fall off.

[0059] The movable rod 232 is located inside the fixed rod 231 and is slidably connected to the fixed rod 231 along the length direction of the fixed rod 231. One end of the movable rod 232 extends into the through hole of the protrusion 221. The movable rod 232 is fixed with a reset plate inside the fixed rod 231.

[0060] The plunger head 233 is located at an end of the fixed rod 231 that extends away from the movable rod 232 . An end of the movable rod 232 that is away from the protrusion 221 is fixedly connected to the plunger head 233 .

[0061] The spring 234 is located inside the fixed rod 231 and is sleeved on the outside of the piston rod. One end of the spring 234 is fixedly connected to the reset plate, and the other end of the spring 234 is connected to the plunger head 233.

[0062] With the above structure, when the rotating shaft 21 is connected to the stirring rod, the movable rod 232 is inserted into the through hole of the protrusion 221, and has good stability and is not easy to fall off. When the stirring rod needs to be disassembled, it is only necessary to pull the plunger head 233, which drives the movable rod 232 to move, and then pull the movable rod 232 out of the through hole of the protrusion 221 to achieve the disassembly between the rotating shaft 21 and the movable rod 232. At this time, the spring 234 is in a compressed state. After the plunger head 233 is released, the spring 234 drives the movable rod 232 and the plunger head 233 to return to their original position. This structure has the advantages of being more stable than a pin connection and easier to disassemble than a bolt.

[0063] like Figure 2 As shown, further, in one implementation of the embodiment of the present application, the stirring device 2 extends from the top of the mixing tank 1, and the bottom of the rotating shaft 21 is connected to the top of the stirring rod 22 through a connecting structure.

[0064] The driving device 3 includes: a motor 31 and a reducer 32. The motor 31 and the reducer 32 are distributed in the vertical direction, and the motor 31 is located directly below the reducer 32. The output shaft of the motor 31 is connected to the reducer 32. The motor 31 generates rotational power and transmits the rotational power to the reducer 32. After receiving the rotational power, the reducer 32 decelerates the rotational power and increases the torque before outputting it.

[0065] The transmission device 4 is disposed above the liquid mixing tank 1 and includes a drive wheel 41, a driven wheel 42, and a synchronous belt 43. The drive wheel 41 is located directly above the reducer 32, and the output shaft of the reducer 32 is fixedly connected to the center of the drive wheel 41. The driven wheel 42 is located directly above the rotating shaft 21, and the top end of the rotating shaft 21 is fixedly connected to the center of the driven wheel 42. The synchronous belt 43 is looped between the drive wheel 41 and the driven wheel 42. The reducer 32 transmits the rotational power to the drive wheel 41, driving the drive wheel 41 to rotate. The drive wheel 41 then drives the driven wheel 42 to rotate via the synchronous belt 43. The driven wheel 42 then drives the rotating shaft 21 to rotate, thereby providing the stirring device 2 with rotational power.

[0066] Furthermore, another implementation in the embodiment of the present application is that the transmission device 4 is arranged below the mixing tank 1, the stirring device 2 extends from the bottom of the mixing tank 1, the top of the rotating shaft 21 is connected to the bottom of the stirring rod 22 through a connecting structure, the reducer 32 is located directly below the motor 31, and the output shaft of the motor 31 is connected to the reducer 32. The reducer 32 is located directly above the driving wheel 41, and the output shaft of the reducer 32 is fixedly connected to the center of the driving wheel 41; the rotating shaft 21 is located directly above the driven wheel 42, and the bottom of the rotating shaft 21 is fixedly connected to the center of the driven wheel 42. The bottom of the stirring rod 22 passes through the bottom wall of the mixing tank 1 and is connected to the rotating shaft 21 through the above-mentioned connecting structure; it is also possible that the top of the rotating shaft 21 passes through the bottom wall of the mixing tank 1 and extends into the interior of the mixing tank 1, and is connected to the stirring rod 22 through the above-mentioned connecting structure.

[0067] In order to avoid leakage of the mixing tank 1 and to facilitate the removal and cleaning of the mixing tank 1 from the polishing equipment, the transmission device 4 is arranged above the mixing tank 1, and the stirring device 2 extends from the top of the mixing tank 1 into the mixing tank 1, which is the preferred solution in the embodiment of the present application.

[0068] In the embodiment of the present application, a beam arm shell 10 is provided on the outside of the transmission device 4 to protect the transmission device 4; a top cover 8 is provided on the top of the mixing tank 1 to protect the mixed liquid in the mixing tank 1 so that impurities are not easily dropped into the mixing tank 1; a avoidance opening 81 is provided below the beam arm shell 10 of the top cover 8 to facilitate the staff to remove the top cover 8 from the mixing tank 1 so that the beam arm shell 10 and the transmission device 4 can pass through the avoidance opening 81 without affecting the removal of the top cover 8; the size of the beam arm shell 10 is just matched with the size of the avoidance opening 81, so that the beam arm shell 10 can block the avoidance opening 81 to prevent impurities from easily falling into the mixing tank 1 from the avoidance opening 81.

[0069] Furthermore, in order to facilitate the staff to add mixed liquid into the mixing tank 1, the mixed liquid storage system also includes a sliding base 6 and a fixed base 7. The mixing tank 1 is placed above the sliding base 6, and the fixed base 7 is located below the sliding base 6. The fixed base 7 is fixedly connected to the bottom plate in the polishing equipment. A sliding rail 71 is installed between the inner side wall of the sliding base 6 and the outer side wall of the fixed base 7 for sliding connection between the sliding base 6 and the fixed base 7. Of course, the sliding mode of the sliding base 6 and the fixed base 7 is not restrictive, and the lower surface of the sliding base 6 can also be slidably connected to the upper surface of the fixed base 7. It can be understood that as long as the sliding base 6 can slide out from above the fixed base 7 in the horizontal direction, it is acceptable. When the staff needs to add mixed liquid into the mixing tank 1, the sliding base 6 can be slid out and the mixing tank 1 can be moved to the outside of the polishing equipment so that there is no obstruction above the mixing tank 1, which further provides convenience for the staff to add mixed liquid into the mixing tank 1.

[0070] like Figure 4 As shown, a positioning member 61 is provided above the sliding base 6. The structure of the positioning member 61 is not limited. The positioning member 61 can be a positioning block fixedly connected to the upper surface of the sliding base 6. The fixing method is also not limited and can be connected and fixed by gluing, welding, clamping, etc. The positioning member 61 can also be a bolt fixedly connected to the upper surface of the sliding base 6 by a threaded connection. Any method can be used as long as it can limit the horizontal movement of the mixing tank 1 on the upper surface of the sliding base 6.

[0071] It should be noted that there are at least four positioning members 61, and of course, a greater number may be provided. At least four positioning members 61 abut against the bottom sidewalls of the mixing tank 1, restricting the mixing tank 1 from moving horizontally in any direction, thereby providing good horizontal stability for the mixing tank 1. To remove the mixing tank 1 from the sliding base 6, simply lift it upward, allowing the bottom of the mixing tank 1 to pass over the positioning members. This structure makes it convenient for personnel to remove the mixing tank 1.

[0072] Furthermore, to improve the stability of the rotating shaft 21 during rotation, a sleeve seat 9 is provided between the top cover 8 and the beam arm housing 10. The sleeve seat 9 is fixedly connected to the lower surface of the beam arm housing 10. An oil-free sleeve is installed inside the sleeve seat 9, and the rotating shaft 21 passes through the oil-free sleeve and is rotatably connected to the oil-free sleeve. Through the above structure, the oil-free sleeve replaces the ordinary deep groove ball bearing in the traditional structure. Ordinary deep groove ball bearings require the addition of lubricating oil. The lubricating oil and metal debris that may be generated during operation will fall into the mixing tank 1, causing contamination of the mixed liquid and even scratching the wafers. The oil-free sleeve effectively avoids the above-mentioned problems.

[0073] Those skilled in the art will readily appreciate other embodiments of the present invention after considering the specification and practicing the embodiments of the present invention. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art that are not covered by this application.
