[0068] In general, compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects:
[0069] 1. The wafer cleaning equipment and the cleaning method of the present invention, through the arranged driving member, after the staff inserts the driving shaft into the external shaft seat, the driving member and the feeding member can form a detachable whole, and by turning on the switch of the second driving motor to rotate the driving shaft, the feeding member can be driven to rotate, so that the feeding member can drive multiple groups of wafers to perform cleaning operations in the cleaning box, and at the same time, the first bevel gear and the second bevel gear can be driven to rotate, so as to drive the cam to rotate. In this process, the counterweight rod sleeve can be arranged to make the extension rod counterweighted when rotating;
[0070] 2. The wafer cleaning equipment and the cleaning method thereof of the present invention, through the arrangement of the first follower shaking component, when the cam rotates, when the raised end of the cam touches the follower roller, it can drive the follower rod to move downward, and at the same time, the stabilizing rod moves downward, and the second spring is compressed, and after the follower rod moves downward, it can drive the follower shaking plate to move downward, so that the follower shaking plate and the tail plate can shake the mixture of the reaction liquid and water along the up and down directions to accelerate the mixing speed between the reaction liquid and the water, when the smooth disk end of the cam contacts the follower roller, it can drive the follower roller back to the initial position when the second spring retracts, and in the process of the follower shaking plate moving downward, it can also drive the tooth plate to move downward, so that the tooth plate drives the first follower gear to rotate, thereby driving the second follower gear to rotate, and at the same time driving multiple groups of cross stirring blades to further accelerate the reaction liquid and The mixing speed between the reaction liquid and the water is improved by driving the second follower gear at the upper and lower ends to rotate when the second follower gear rotates, so as to drive the cross stirring blades at the upper and lower ends to rotate, so as to accelerate the mixing speed between the reaction liquid and the water in multiple directions. By accelerating the mixing speed between the reaction liquid and the water, the reaction speed between the impurities on the wafer and the mixed liquid can be further promoted. As the follower shaking plate moves downward, the resistance encountered is gradually increased. Therefore, by gradually increasing the number of teeth of the tooth plate from bottom to top, the meshing time between the tooth plate and the first follower gear is increased from bottom to top, which can further extend the rotation time of the second follower gear to accelerate the mixing between the reaction liquid and the water. In addition, in the process of the follower shaking plate moving upward, the cross stirring blade can be driven to reverse to promote the mixing operation of the mixed liquid and the water.
[0071] 3. The wafer cleaning equipment and the cleaning method of the present invention can extract the reaction liquid in the liquid replenishing box into the liquid replenishing pipe by opening the switch of the suction pump through the arranged liquid replenishing member, and the reaction liquid flows out through the liquid outlet end of the liquid replenishing pipe and falls through the liquid outlet bucket. In the process of the feeding pushing member stretching the driving member to move upward, the liquid replenishing member can be synchronously driven to move upward. At this time, the second vertical plate can be extended and retracted up and down in the first vertical plate to cooperate with the feeding pushing member to stretch and move the driving member upward;
[0072] 4. The wafer cleaning equipment and the cleaning method of the present invention, through the arranged linkage stirring components, when the staff makes the toothed disc penetrate until it conflicts with the multiple groups of meshing wheels, when the toothed disc meshes with the meshing wheels, it can drive the four groups of stirring shafts to rotate, so as to drive the four groups of dragon blades to rotate, so as to drive the horizontal axis and the inclined blades to rotate, so that the dragon blades and the inclined blades can stir the reaction liquid and water to accelerate the reaction between the mixed liquid and water, and when the reaction liquid and water are fully mixed, the reaction between the mixed liquid and the impurities on the wafer can be further accelerated to accelerate the cleaning operation of the wafer;
[0073] 5. The wafer cleaning device and the cleaning method of the present invention, through the arranged linkage blocking components, after the staff drives the driving shaft to rotate, since the driving shaft is connected with the collar, the collar can be driven to rotate and the sleeve can be driven to rotate. As the rotation speed of the driving component increases, the centrifugal force on the linkage block is increased, and the linkage block can be moved outward along the direction of the frame notch. After the two groups of linkage blocks move outward, the collar can be driven to move downward as a whole, and after the collar moves downward , and can drive the side rod and the sealing plate to move downward. After the sealing plate moves downward, the through hole can be replaced so that the small through hole is replaced by a through hole with an increased aperture, which can further accelerate the outflow speed of the reaction liquid in the liquid replenishing tube, so as to accelerate the speed of the reaction liquid flowing into the cleaning box. When the concentration of the reaction liquid in the cleaning box is improved, the reaction speed of the impurities on the wafer can be further accelerated. After the rotation speed of the driving shaft is increased, the rotation speed of the feeding part can be further accelerated, so as to accelerate the rotation speed of the wafer, so as to promote the cleaning speed of the wafer in the cleaning box;
[0074] 6. The wafer cleaning device and the cleaning method of the present invention can drive the bonding disk to rotate by rotating the driving shaft through the arranged second follower shaking member. When the first permanent magnetic ring rotates to correspond to the permanent magnetic plate, due to the principle of magnetic repulsion, the permanent magnetic plate can be driven to move backward. On the one hand, the permanent magnetic plate can drive the pressing wheel to vibrate the inner wall of the cleaning box to prevent impurities from staying on the inner wall of the cleaning box. On the other hand, when the permanent magnetic plate moves backward, the mixed liquid of the reaction liquid and water can be further shaken in the front-to-back direction. The liquid can be shaken in the up-down and front-to-back directions in cooperation with the first follower shaking member at the same time to further accelerate the mixing between the reaction liquid and water. When the non-magnetic ring moves to correspond to the permanent magnetic plate, the fourth spring can retract when it loses compression to push the permanent magnetic plate back to its initial position.
[0075] 7. The wafer cleaning equipment and the cleaning method of the present invention, through the arranged heating components, when the staff turns on the switch of the heating tube, on the one hand, the cleaning box can be annularly heated by the heating frame. By heating the mixture of the reaction liquid and water in the cleaning box, the thermal motion between the liquid molecules can be accelerated and the collision frequency between the molecules can be increased. The increase in the collision frequency is conducive to the uniform distribution and mixing between different liquid components. On the other hand, after being heated by the heating tube, the airbag can be expanded by heat to push the lower pressure plate and the upper pressure plate to move up. When the upper pressure plate moves up, it can push the liquid supply bag to release the reaction liquid into the cleaning box through the nozzle. By replenishing the liquid in the cleaning box, it can be prevented that the reaction liquid reacts with the impurities on the wafer, resulting in a decrease in the concentration of the reaction liquid and a decrease in the cleaning efficiency of the wafer. By increasing the rotation speed of the drive shaft, the cleaning efficiency of the wafer can be accelerated synchronously. On the other hand, it can promote the up and down shaking frequency of the first follow-up shaking component, on the other hand, it can promote the front and back shaking frequency of the second follow-up shaking component, and finally on the other hand, it can synchronously increase the feeding speed of the liquid replenishing component.

[0097] The present invention is based on an overall idea that, through the arrangement of the driving member 4, after the staff inserts the driving shaft 43 into the external shaft seat 373, the driving member 4 and the feed member 37 can form a detachable whole, and by turning on the switch of the second driving motor 41, the driving shaft 43 can be rotated, which can drive the feed member 37 to rotate, so that the feed member 37 can drive multiple groups of wafers to perform cleaning operations in the cleaning box 11.
