Abstract
Description
Technical Field

[0002] The diamond dresser is a dressing wheel on the polishing equipment. It is mainly placed on the matching polishing machine disk and performs planetary rotation. The diamond sheet on the dresser is used to grind the surface of the polishing pad so that the polishing pad meets the parameter requirements. With the development of current industrial technology, the surface of the polishing pad can be ground flat with the help of the graphical distribution of the particle matrix based on the brazing process.
[0003] In the prior art (Patent No. CN218904866U, Patent Name: Diamond Dresser for Double-Sided CMP Polishing Machine), the arrangement of a base wheel, mounting slots, tenon pins, gear ring, reinforcement plate, circular groove, diamond pellets, and tenon joints achieves enhanced overall strength within the thinner section of the dresser through the reinforcement plate. During the implementation of this technical solution, it was discovered that the prior art at least had undisclosed issues regarding dust disposal and frictional heat dissipation generated during polishing pad dressing.

The bottom of the rotating shaft 74 is fixedly connected to a driving circular gear 75. The first and second flattening toothed discs 76 and 77 are respectively meshed around the driving circular gear 75.

A connecting rod 85 is fixedly connected to the rotating sleeve 84, and the other end of the connecting rod 85 is hinged with a piston 86 that slides with the top cylinder 4.

[0056] The Y-shaped dust suction tube 87 and the large-diameter dust suction head 88 are distributed in a triangular equidistant state along the central axis of the dust cover 3, so that the Y-shaped dust suction tube 87 and the large-diameter dust suction head 88 are reasonably distributed, and the particulate dust dispersed in the dust cover 3 is comprehensively vacuumed.

In addition, the inner cavity of the placement table 107 is provided with a leakage screen 108 used in conjunction with the driving circular gear 75, the first leveling tooth disc 76 and the second leveling tooth disc 77, so that the granular dust generated on the bottom surface of the polishing pad can fall into the dust box 105 through the leakage screen 108, which is convenient for later cleaning.

[0060] like Figure 7 and Figure 16 As shown, during the grinding of the polishing pad, when the polishing pad is ground with a grinding disc, heat is generated due to friction, resulting in heat accumulation in the polishing pad area, which cannot be effectively cooled and evacuated. Over time, under the dual influence of the friction of the grinding disc and the condensed heat, the grinding quality of the polishing pad is affected, and even the polishing pad is deformed during grinding. A cooling component 11 is provided on all four sides of the annular frame 2, and the cooling component 11 includes a second boosting pipe 111, the second boosting pipe 111 is connected to the outer end of the boosting three-way valve 95, and the top end of the second boosting pipe 111 is connected to a four-way joint 112, and the top end of the four-way joint 112 is unidirectionally connected to a refrigerator 113, firstly, three groups of refrigerators 113 provide a cold source supply, and then the three-way boosting gas in the three groups of second boosting pipes 111 boosts and transports the cold source;
[0061] Both ends of the four-way joint 112 are connected to an elbow 114, and the end of the elbow 114 away from the four-way joint 112 is connected to an arc-shaped main pipe 115 fixedly matched with the ring frame 2. The inner cavity of the ring frame 2 is provided with air blowing ports 116 used in conjunction with the arc-shaped main pipe 115. The three-way cold source of the boosted transmission is transmitted through the three groups of elbows 114 and the three groups of air blowing ports 116 on the arc-shaped main pipe 115 to the ring frame 2 sealed by the dust cover 3, so as to cool the polishing pad in the grinding state. Processing is performed to prevent the first flattening toothed disc 76 and the second flattening toothed disc 77 from overheating during the polishing pad grinding, causing quality problems. The first flattening toothed disc 76 and the second flattening toothed disc 77 are provided with a first air guide port 117 and a second air guide port 118 for use with the air outlet 116 around them, which is beneficial to the diversion of the pressurized cold source in the first flattening toothed disc 76 and the second flattening toothed disc 77, so that the pressurized cold source is quickly and comprehensively distributed in the internal area of the annular frame 2, thereby improving the comprehensiveness and effectiveness of the cooling and heat dissipation of the polishing pad;
[0062] like Figures 18 to 21 As shown, mounting grooves 15 are provided around the top and bottom of the inner cavity of the first leveling toothed disc 76, and the inner cavity of the mounting groove 15 is respectively provided with a fixed end cover 16 and an arc-shaped polishing block 17, which is used to grind the polishing pad in an arc-shaped manner. Stud screws 18 used in conjunction with the fixed end cover 16 and the arc-shaped polishing block 17 are inserted around the mounting groove 15, and the fixed end cover 16 and the arc-shaped polishing block 17 are tightened and fixed to improve the installation stability of the fixed end cover 16 and the arc-shaped polishing block 17. The top of the stud screw 18 is threadedly connected with a nut 19, which is tightened and fixed to prevent the stud screw 18 from falling off. The bottom of the first leveling toothed disc 76 is provided with a first cleaning head 23 staggered with the arc-shaped polishing block 17 around the four sides to clean the particles and dust on the surface of the polishing pad during grinding.
[0063] The second leveling toothed disc 77 is provided with mounting holes 20 around its inner cavity, and a circular polishing block 22 is provided in its inner cavity. A single-head screw 21 threadably matched with the circular polishing block 22 is inserted into the inner cavity of the mounting hole 20 to tighten and fix the circular polishing block 22. Second cleaning heads 24 staggered with the circular polishing block 22 are provided around the bottom of the second leveling toothed disc 77 to clean the particle dust on the surface of the polishing pad during grinding, especially the stubborn particle dust adhered to the polishing pad due to grinding and crushing by the first leveling toothed disc 76 and the second leveling toothed disc 77, which provides convenience for subsequent dust suction and dust removal.
[0064] Specifically, the working principle of the diamond dresser and its flattening device based on the graphical distribution of the particle matrix of the brazing process is as follows: first, the fixed end cover 16 and the arc-shaped polishing block 17 are respectively installed on the upper and lower surfaces of the mounting groove 15 on the first flattening tooth disc 76, and then the double-headed screw 18 is screwed into the reserved screw holes in the fixed end cover 16 and the arc-shaped polishing block 17, and the nut 19 is tightened on the top of the double-headed screw 18 using a hexagonal wrench, and then the first cleaning head 23 is installed at the bottom of the first flattening tooth disc 76 to complete the fixing of the end cover 16 and the arc-shaped polishing block 17 on the first flattening tooth disc. After the installation work on the disc 76, the single-head screw 21 and the circular polishing block 22 are respectively inserted into the upper and lower surfaces of the mounting hole 20 on the second leveling toothed disc 77. The single-head screw 21 is screwed into the circular polishing block 22 using the hexagonal wrench again. The second cleaning head 24 is then installed at the bottom of the second leveling toothed disc 77. The installation work of the single-head screw 21 and the circular polishing block 22 on the second leveling toothed disc 77 is completed. The two sets of the first leveling toothed disc 76 and the second leveling toothed disc 77 are meshed between the driving circular gear 75 and the fixed gear ring 78 in an axially symmetrical staggered distribution pattern.
[0065] After the preparation work is completed, the servo motor 71 is controlled to start and drive the main synchronous wheel 72 to rotate. The main synchronous wheel 72 drives the rotating shaft 74 on the slave synchronous wheel 73 to rotate accordingly through the synchronous belt. The rotating shaft 74 drives the driving circular gear 75 to rotate accordingly. The driving circular gear 75 drives the two sets of first flattening toothed discs 76 and second flattening toothed discs 77 that are axially symmetrical and staggered to rotate along the fixed gear ring 78 on the polishing pad. The two sets of first flattening toothed discs 76 and second flattening toothed discs 77 drive the two sets of arc-shaped polishing blocks 17 and circular polishing blocks 22 that are axially symmetrical and staggered and have different shapes to rotate and grind the polishing pad.
[0066] The dust cover 3 seals and dust-proofs the annular frame 2. While the polishing pad is being polished, the rotating shaft 74 also drives the driving bevel gear 81 to rotate. The driving bevel gear 81 drives the concave rod frames 83 on the three sets of driven bevel gears 82 to rotate synchronously. The three sets of concave rod frames 83 drive the pistons 86 on the three sets of connecting rods 85 through the three sets of rotating sleeves 84 to perform reciprocating work in the three sets of top cylinders 4. When the three sets of pistons 86 perform a return suction state in the three sets of top cylinders 4, the suction valves on the three sets of Y-shaped dust suction pipes 87 are opened, and the exhaust valves on the three sets of dust exhaust pipes 91 are closed. Then, the negative pressure suction force generated by the three sets of pistons 86 in the three sets of top cylinders 4 is sucked away by the large-caliber dust suction heads 88 on the three sets of Y-shaped dust suction pipes 87.
[0067] When the three groups of pistons 86 are in the exhaust state of the process in the three groups of top cylinders 4, the suction valves on the three groups of Y-shaped dust suction pipes 87 are closed, and the exhaust valves on the three groups of dust discharge pipes 91 are opened. Then, the three groups of pistons 86 will suck the particulate dust in the three groups of top cylinders 4 through the three groups of dust discharge pipes 91 and discharge them into the dust collecting cylinder 92 with pressure. Then, the three groups of upper filter racks 93 and lower filter racks 94 perform double filtration on the pressurized particulate dust. The pressure of the filtered pressurized gas is pressurized again by the three groups of boosting three-way valves 95 and detected by the three groups of pressure gauges 96. Then, it is supplied to the three groups of four-way joints 112 through the three groups of second boosting pipes 111, and the three groups of refrigerators 113 are controlled to open in advance and the cold source is supplied to the three groups of four-way joints 112 to merge with the filtered and pressurized boosted gas. Then, the three-way boosting cold source The arc-shaped main pipe 115 on the three sets of curved pipes 114 supplies air to the enclosed space formed by the annular frame 2 and the dust cover 3 through the blowing port 116. With the cooperation of the first air guide port 117 and the second air guide port 118 on the two sets of first leveling toothed discs 76 and second leveling toothed discs 77, the three-way pressurized cold source is quickly distributed in the annular frame 2 and the dust cover 3, thereby cooling the heat generated during the grinding of the polishing pad and blowing away the particulate dust generated during the grinding of the polishing pad. The first cleaning head 23 and the second cleaning head 24 under the two rotating sets of first leveling toothed discs 76 and second leveling toothed discs 77 clean and lift the particulate dust attached to the polishing pad, thereby facilitating the dust collection work of the three sets of large-caliber dust suction heads 88.
[0068] After the polishing pad completes the grinding, dust collection, dust removal and cooling work, the pressure relief valves on the three sets of pressure relief pipes 98 are controlled to open, and the boosted pressure in the three sets of bottom cylinders 6 is discharged by the three sets of pressure relief pipes 98. Then, the three sets of slides 102 that have lost the pressure force are quickly driven by the elastic reset pull of the three sets of return springs 103 to move down and reset to the lowest state on the three sets of lifting rods 104. After the placement table 107 moves down to its full position, it separates the polishing pad that has been ground from the two sets of first leveling tooth discs 76 and second leveling tooth discs 77 to the initial state through the mesh plate 108. After that, the worker removes the polishing pad that has been ground from the mesh plate 108. If it is necessary to grind the other side of the polishing pad, it can be directly turned downward with the ground side facing down and the other side of the polishing pad that has not been ground facing up for grinding. The pressure relief valves on the three sets of pressure relief pipes 98 are controlled to close.
[0069] If a new polishing pad needs to be replaced, similarly, the pressurized gas in the three groups of pressurized three-way valves 95 is supplied to the three groups of bottom cylinders 6 on the base 5 through the three groups of first pressurized pipes 97. As the three-way pressurized gas is continuously supplied and a pressurized pressure force is formed at the bottom of the inner cavity of the three groups of bottom cylinders 6, under the action of the pressurized pressure force, the three groups of vertical grooves 101 and the sliders 106 provide sliding limit compensation for the placement table 107. Then, the pressurized pressure force in the three groups of bottom cylinders 6 forces the three groups of slides 102 to drive the dust collection box 105 and the placement table 107 on the three groups of lifting rods 104 to slide upward in the three groups of bottom cylinders 6, and drives the three complex rods 106 to move upward. The positioning spring 103 is stretched upward until the convex block 13 on the annular frame 2 is clamped with the concave groove 14 in the placement table 107, and the newly replaced polishing pad is re-fitted with the arc-shaped polishing block 17 and the circular polishing block 22 on the two sets of first leveling toothed discs 76 and second leveling toothed discs 77. Similarly, the polishing pads are subjected to batch grinding operations, and the granular dust generated below during the grinding of the polishing pads falls into the dust collecting box 105 through the mesh plate 108, and then the three sets of pull-out boxes 12 are regularly pulled out of the dust collecting box 105 to clean the granular dust accumulated in the dust collecting box 105.
