[0002] At present, in the prior art, the wafer is fixed on the iron ring by the adhesive film for subsequent operation, and the iron ring also plays a protective role for the wafer. After the product with the iron ring flows through the entire process section and the operation is completed, the adhesive film needs to be removed from the iron ring, so that the iron ring can be reused. Since the current residual adhesive cleaning is manually performed by personnel, the efficiency is low, and not all personnel will perform according to the operation standard, which brings potential risks to the production operation. After the wafer is removed from the iron ring, the iron ring is transported to the adhesive removal area. Since the processes of the front and rear sections are not the same, the phenomenon of iron ring accumulation is prone to occur. Since the uncleaned iron ring adheres to the adhesive film, if the accumulation occurs, the problem of difficult disassembly will occur. The stacked iron rings also affect the subsequent cleaning effect. SUMMARY

[0015] Example 1 like Figures 1-3 As shown, a cleaning device for iron rings 4, in this embodiment, includes a receiving section 2, a de-adhesive tank 1, and a discharging section 3. The receiving section 2 is used to receive the horizontally conveyed iron rings 4 and rotate the iron rings 4 90° to place them into the de-adhesive tank 1. The discharging section 3 is used to receive the de-adhesive iron rings 4 in the de-adhesive tank 1 and rotate the iron rings 4 90° before horizontally outputting them. Because in continuous production operations, the cleaning operation of the iron rings 4 involves rotating them 90° and distributing them sideways in the de-adhesive tank 1, so as many iron rings 4 as possible can be arranged in the limited space of the de-adhesive tank 1, and two adjacent sets of iron rings 4 will not press on the glue that has not been cleaned off on the side, thus affecting the cleaning effect. The de-adhesive tank 1 is a cylindrical ultrasonic cleaning tank. A set of support rings 12 is provided on the outer ring of the bottom of the ultrasonic cleaning tank, and a support frame 13 is placed on the support rings 12 and driven by a set of central motors 14. The central motor 14 is installed on the top cover of the ultrasonic cleaning tank. The support frame 13 includes an inner column 131 located in the center and driven to rotate by the central motor 14, and multiple sets of U-shaped rotating grooves 132 fixed around the inner column 131 and evenly distributed in the circumferential direction. The outer bottom of the U-shaped rotating groove 132 is placed on the support ring 12. Each set of U-shaped rotating grooves 132 is also guided and connected to a set of U-shaped receiving grooves 133. The bottom of the U-shaped receiving groove 133 is set to be arc-shaped to cooperate with the circumferential direction of the iron ring 4. The U-shaped receiving groove 133 is also provided with conical slots 134 that limit the iron ring 4 on both sides. The iron ring 4 is placed in the U-shaped receiving groove 133 and limited by the inclined surfaces on both sides of the conical slots 134. The top cover is also provided with a channel opening corresponding to the material receiving section 2 and the material discharge section 3 for receiving the side-standing iron ring 4 for feeding or discharging. At this point, the ultrasonic cleaner 11 installed at the bottom of the ultrasonic cleaning tank is started, and the cleaning liquid in the ultrasonic cleaning tank can be used to remove the adhesive on the side surface of the iron ring 4 placed therein. When the U-shaped receiving groove 133 is rotated to the channel opening, the receiving section 2 flips the horizontally transported iron ring 4 by 90° and places it into the degreasing tank 1, and the discharging section 3 takes the degreased iron ring 4 from the degreasing tank 1 and flips it by 90° before horizontally outputting it. In the cleaning operation of the ultrasonic cleaning tank, a plurality of groups of U-shaped rotating grooves 132 arranged around the inner column 131 can realize the cleaning operation of a plurality of groups of iron rings 4, thereby meeting the continuous cleaning operation of a large number of iron rings 4 while ensuring a small overall equipment footprint.

[0016] The bottom of each group of U-shaped rotating grooves 132 is also provided with a group of ejection channels 135, and a group of ejection cylinders 15 is installed at the bottom of the ultrasonic cleaning tank corresponding to the channel opening. The driving end of the ejection cylinder 15 passes through the ejection channel 135 through a top rod to eject the U-shaped receiving groove 133. The top cover of the ultrasonic cleaning tank is also provided with two groups of n-shaped support frames 16 corresponding to the receiving section 2 and the discharging section 3. The receiving section 2 and the discharging section 3 each include a receiving conveying line and a flipping part installed on the n-shaped support frame 16. The flipping part is used to realize the flipping transition of the iron ring 4 between the receiving conveying line and the channel opening. The flipping part includes a clamping cylinder one 21 installed on the top of the n-shaped support frame 16 and corresponding to the channel opening above, two groups of driving cylinders 22 horizontally slidingly installed on both sides of the n-shaped support frame 16, a driving lead screw 23 for driving the driving cylinders 22 to horizontally transition between the receiving conveying line and the channel opening, a rotating cylinder 24 installed on the driving end of the corresponding driving cylinder 22, and a clamping cylinder two 25 installed on the driving end of the rotating cylinder 24. In the discharge section 3, the ejector cylinder 15 ejects the U-shaped receiving groove 133, causing the iron ring 4 inside the U-shaped receiving groove 133 to detach from the ultrasonic cleaning tank and rise to the opening end of the clamping cylinder 21. The clamping cylinder 21 then clamps the top of the iron ring 4, the ejector cylinder 15 descends, and the U-shaped receiving groove 133 also descends under gravity and is repositioned in the corresponding U-shaped rotating groove 132. Then, the clamping cylinder 25 moves towards the other side under the drive of the drive cylinder 22 to clamp both sides of the iron ring 4. The jaws of the clamping cylinder 21 then open to loosen the clamping of the iron ring 4. The rotating cylinder 24, through the clamping cylinder 25, drives the iron ring 4 to rotate 90° and flip to a horizontal position. Finally, the drive screw 23 rotates to rotate the iron ring 4 in the receiving and conveying process. The material is transferred horizontally above the channel opening. Similarly, in receiving section 2, clamping cylinder 25 drives the iron ring 4 to be sent above the channel opening. Then, under the drive of rotating cylinder 24, it rotates 90°, so that the iron ring 4 is upright on its side. The jaws of clamping cylinder 1 21 close to clamp the top of the iron ring 4, while clamping cylinder 25 moves backward and retracts under the drive of driving cylinder 22. Then, ejecting cylinder 15 ejects the U-shaped receiving groove 133, so that the iron ring 4 is stuck into the U-shaped receiving groove 133. Then, clamping cylinder 1 21 opens to release the top of the iron ring 4. Ejecting cylinder 15 descends, so that the U-shaped receiving groove 133 descends into the U-shaped rotating groove 132. At this point, the iron ring 4 enters the ultrasonic cleaning tank for cleaning. Since the rising and falling of the iron ring 4 in the ultrasonic cleaning tank is carried out within the U-shaped receiving groove 133, the iron ring 4 can be prevented from being directly detached from the U-shaped receiving groove 133 and being affected by the impact of the cleaning liquid, thereby improving the stability of the iron ring 4 during the transition.

[0017] The receiving conveyor line consists of two sets of parallel belt conveyor lines, and a centering structure 5 is set in the middle of the two sets of belt conveyor lines. The centering structure 5 is used to center the iron ring 4 before the clamping cylinder 25 of the receiving section 2 clamps the horizontally conveyed iron ring 4, so as to better align the channel opening and the U-shaped receiving groove 133 when the two sets of clamping cylinder 25 clamp the two sides of the iron ring 4 and transition to the top of the channel opening.

[0018] The centering structure 5 includes a fixed block 51 arranged at the center of the two groups of belt conveying lines and a rectangular telescopic block 52 sleeved at both ends of the fixed block 51. A group of rotating lead screws 53 are also installed in the fixed block 51. The two ends of the rotating lead screws 53 are screwed into the two groups of rectangular telescopic blocks 52. A group of lead screw motors 54 are installed on the fixed block 51. The driving end of the lead screw motor 54 is engaged with the outer gear ring at the center of the rotating lead screw 53 through a gear 55. The outer gear ring is also located at the center of the two groups of belt conveying lines. When the rotating lead screw 53 rotates, the two groups of rectangular telescopic blocks 52 move away from each other or towards each other. The end of each of the two groups of rectangular telescopic blocks 52 is also installed with a group of rollers 56 for pressing on both ends of the inner ring of the iron ring 4. Thus, when the rollers 56 press on both ends of the inner ring of the iron ring 4, the center of the iron ring 4 can be driven to the center of the two groups of belt conveying lines, and then the clamping cylinder two 25 is driven to move to the two sides of the aligned outer gear ring. At this time, the clamping cylinder can be symmetrically clamped at both ends of the iron ring 4.

The bottom end of the extension spring 17 is fixed in the corresponding U-shaped rotating groove 132. Therefore, when the ejecting cylinder 15 ejects the U-shaped receiving groove 133, the ejecting cylinder 15 retreats, and the U-shaped receiving groove 133 can be pulled into the U-shaped rotating groove 132 under the stretching force of the extension spring 17.
