Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a grind clean subassembly and grind cleaning device to solve the current clean subassembly machining efficiency of grinding low and the unstable problem of inner structure. Which will be described below with reference to the accompanying drawings.
The grinding and cleaning assembly provided by the embodiment of the application can be applied to a grinding and cleaning device. Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of an abrasive cleaning element according to an embodiment of the present disclosure. FIG. 2 is a schematic partial cross-sectional view of an abrasive cleaning assembly according to an embodiment of the present disclosure. Figure 3 is a schematic partial cross-sectional view of an abrasive cleaning assembly according to another embodiment of the present disclosure. The abrasive cleaning assembly includes: the rotating shaft 10, the peripheral wall of the rotating shaft 10 is provided with a key groove 11; a flat key 20 including a first fitting portion mounted to the key groove 11 and a second fitting portion protruding from a notch of the key groove 11; the first sleeve 30 is sleeved on the rotating shaft 10, a sliding groove 31 extending along the axial direction is formed in the inner peripheral wall of the first sleeve 30, and the sliding groove 31 and the second matching part are in sliding fit in the axial direction and are relatively fixed in the circumferential direction; the second sleeve 40 is sleeved on the first sleeve 30; the bearing 50 is arranged between the first sleeve 30 and the second sleeve 40, the inner ring of the bearing 50 is fixedly matched with the first sleeve 30, and the outer ring of the bearing 50 is fixedly matched with the second sleeve 40; and a grinding disc 60 mounted at one end of the rotating shaft 10.
In this embodiment, specifically, the rotating shaft 10 is used to connect with a driving device of the polishing and cleaning device, the driving device is connected to an end of the rotating shaft 10 away from the polishing disk 60, and the driving device can drive the rotating shaft 10 to rotate and move axially. The shaft 10 drives the grinding disc 60 to rotate together, the grinding disc 60 rotates along the surface of the glass substrate, and under the auxiliary action of the cleaning agent, the impurities such as dust attached to the surface of the glass substrate can be removed. Since the radial dimension of the grinding disc 60 is larger than that of the rotating shaft 10, when the grinding disc 60 works, the shaft end connected with the grinding disc 60 can vibrate radially, which affects the grinding and cleaning effect of the grinding disc 60.
The second sleeve 40 is used for being fixed on a fixing frame of the grinding and cleaning device and is rotatably matched with the first sleeve 30 through the bearing 50, torque can be transmitted between the first sleeve 30 and the rotating shaft 10 through the flat key 20, that is, the rotating shaft 10 can drive the first sleeve 30 to rotate relative to the second sleeve 40, and radial vibration generated by the rotating shaft 10 can be effectively absorbed and buffered by the second sleeve 40 because the second sleeve 40 is fixed, so that vibration generated by the grinding disc 60 can be reduced, the rotating precision of the grinding disc 60 is improved, and the grinding and cleaning effect is improved.
The flat key 20 is slidably engaged with the sliding slot 31, so that the rotating shaft 10 can move axially relative to the first sleeve 30, i.e. can extend and retract relative to the first sleeve 30 and the second sleeve 40. In the polishing and cleaning device, the first sleeve 30 and the second sleeve 40 are fixed in the axial direction, and the rotating shaft 10 can drive the polishing disc 60 to extend and retract relative to the first sleeve 30 and the second sleeve 40, so that the polishing disc 60 can be close to or far away from the glass substrate in different polishing and cleaning stages to achieve polishing and cleaning work or avoid the glass substrate.
The number of the flat keys 20 can be one or more; for example, the number of the flat keys 20 may be multiple, multiple flat keys 20 are arranged at intervals along the circumferential direction of the rotating shaft 10, and the number and the positions of the key slots 11 and the sliding slots 31 correspond to those of the flat keys 20; in this way, the position of torque transmission between the rotating shaft 10 and the first sleeve 30 can be increased to improve the rotational stability of the first sleeve 30. According to the grinding and cleaning assembly provided by the embodiment of the application, the rotating shaft 10 and the first sleeve 30 are relatively fixed in the circumferential direction through the flat key 20 and can relatively slide in the axial direction, so that the rotating shaft 10 can extend and retract relative to the first sleeve 30 and the second sleeve 40, and the grinding disc 60 is close to or far away from a grinding and cleaning station as required; the torque of the rotating shaft 10 can also be transmitted to the first sleeve 30 through the flat key 20, so that the first sleeve 30 can rotate relative to the second sleeve 40; the second sleeve 40 is configured to be fixed to an external structure to fix the first sleeve 30 in the axial direction, so that the rotating shaft 10 and the first sleeve 30 are prevented from being vibrated in the radial direction to improve the rotating accuracy of the rotating shaft 10. Compared with a grinding and cleaning mechanism using a ball spline shaft, the assembly structure of the rotating shaft 10, the flat key 20 and the first sleeve 30 is simpler in the application, so that the assembly process of the grinding and cleaning assembly can be simplified, and the assembly efficiency is improved.
The flat key 20 may be square or strip, and it is not limited herein, only that the flat key 20 can be slidably fitted with the sliding groove 31. Referring to fig. 5, fig. 5 is an exploded view of an exemplary abrasive cleaning assembly according to an embodiment of the present disclosure. The flat key 20 extends along the axial direction of the rotating shaft 10, and the shape and the size of the key groove 11 are matched with those of the flat key 20; the sliding grooves 31 extend through the end walls of both ends of the first sleeve 30. The flat key 20 is long, so that the contact area with the sliding groove 31 can be increased, and the stability of torque transmission between the rotating shaft 10 and the first sleeve 30 is further improved. In addition, the relative limit displacement of the rotating shaft 10 in the axial direction can be increased; it can be understood that when the rotating shaft 10 moves axially to the limit position relative to the first sleeve 30, the flat key 20 is always partially located in the sliding slot 31.
Illustratively, the ratio of the dimension of the first mating portion in the depth direction of the key groove 11 to the dimension of the second mating portion in the depth direction of the key groove 11 is 1/4 to 1/2, and may be 1/4, 1/3, 1/2, for example. The dimension of the flat key 20 in the depth direction of the key groove 11 can be understood as the thickness of the flat key 20, and the first matching part is the part of the flat key 20 in the key groove 11, and the second matching part is the part of the flat key 20 in the sliding groove 31; the thickness ratio of the first matching part to the second matching part is set to be 1/4-1/2, so that the matching stability of the flat key 20 and the sliding groove 31 can be ensured, and the slotting depth of the sliding groove 31 can be reasonably controlled, so that the stability of the whole structure of the first sleeve 30 can be ensured.
Each side wall of the second engaging portion may abut against a groove wall of the slide groove 31, or a gap may be formed between a part of the side wall and the groove wall of the slide groove 31. Referring to fig. 4, fig. 4 is a schematic partial cross-sectional view of an abrasive cleaning assembly according to another embodiment of the present disclosure. A gap is formed between one surface of the second matching part, which is deviated from the key groove 11, and the groove bottom of the sliding groove 31, the pushing of the flat key 20 to the groove wall of the sliding groove 31 cannot be influenced by the gap, that is, the transmission of torque between the rotating shaft 10 and the first sleeve 30 cannot be influenced, and the friction area between the flat key 20 and the groove bottom of the sliding groove 31 can be reduced, so that the friction force received when the rotating shaft 10 moves axially can be reduced, and the axial movement process of the rotating shaft 10 is smoother.
The side wall of the second matching part can be a cambered surface or a plane. For example, a sliding rib (not shown) is convexly provided on a side wall of the second mating portion, a surface of the sliding rib facing the groove wall of the sliding groove 31 is a convex arc surface, and the sliding rib is slidably abutted against the groove wall of the sliding groove 31. The convex arc surface can reduce the contact area between the flat key 20 and the groove wall of the sliding groove 31, so that the sliding friction between the flat key 20 and the groove wall of the sliding groove 31 can be reduced, the resistance applied to the axial movement process of the rotating shaft 10 can be reduced, and the stability of the axial movement of the rotating shaft 10 can be further improved.
The flat key 20 may be mounted to the key groove 11 by a fixed fit, or by other fixing means. Illustratively, as shown in fig. 5 and 6, fig. 6 is an exploded cross-sectional view of an abrasive cleaning assembly according to an embodiment of the present disclosure. The flat key 20 is provided with a through hole which penetrates through the first matching part and the second matching part; the bottom of the key groove 11 is provided with a fixing hole corresponding to the via hole, and the fixing hole and the via hole are fixedly assembled through a fastener. In combination with the embodiment that the flat key 20 extends along the axial direction, the number of the fixing holes may be two, the two fixing holes are respectively opened at two ends of the flat key 20 in the length direction, and the number of the through holes corresponds to the number of the fixing holes, so that the fixing positions of the flat key 20 and the key groove 11 can be increased, and the installation stability of the flat key 20 can be improved. The flat key 20 can also be provided with a positioning hole which is arranged in the middle of the flat key 20 in the length direction; the bottom of the key groove 11 can be provided with a positioning pin, and before the fastener is installed, the positioning pin penetrates through the positioning hole, so that the flat key 20 can be positioned, and the position deviation in the fastening process is avoided.
Illustratively, as shown in fig. 2 and 3, both ends of the first sleeve 30 in the axial direction protrude from both ends of the second sleeve 40 in the axial direction. The second sleeve 40 is fixed relative to the rotating shaft 10, and the first sleeve 30 can rotate synchronously with the rotating shaft 10 and the grinding disc 60, so that even if the rotating shaft 10 rotates axially to make the grinding disc 60 abut against the first sleeve 30, the rotation of the grinding disc 60 will not be affected, and the working stability of the grinding and cleaning assembly can be improved.
The abrasive cleaning assembly typically uses water as a cleaning medium to abrasively clean the glass substrate, and thus operates in a wet environment. If moisture enters the first sleeve 30 to rust the flat key 20, the fitting accuracy of the flat key 20 and the sliding groove 31 may be affected, and thus the torque transmission process between the rotating shaft 10 and the first sleeve 30 may be affected. If the gap between the flat key 20 and the groove wall of the sliding groove 31 is too large, the first sleeve 30 cannot be completely synchronized with the rotating shaft 10 during the rotation of the rotating shaft 10, so that the first sleeve 30 shakes, and the rotation precision and the grinding effect of the grinding disc 60 are affected.
In order to solve the above problem, as shown in fig. 2, the polishing cleaning assembly provided by the embodiment of the present application further includes a first sealing ring 32, the first sealing ring 32 is installed at one end of the first sleeve 30 close to the polishing disc 60, and the first sleeve 30 is in sealing fit with the wall of the rotating shaft 10 through the first sealing ring 32.
The steam that the one end that first sleeve 30 is close to abrasive disc 60 was splashed more easily by abrasive disc 60 gets into, consequently, sets up first sealing washer 32 between the internal perisporium of first sleeve 30 and the periphery wall of pivot 10, can prevent effectively that steam from getting into corrodes flat key 20 in the first sleeve 30 to improve the sealed protection effect to flat key 20, thereby guarantee to grind the inner structure stability of clean subassembly, the life of the clean subassembly of extension grinding.
Illustratively, the first seal ring 32 is a lip seal, such as a Y-seal or a V-seal. The lip type seal ring can increase a contact area with the circumferential wall of the rotation shaft 10, thereby improving a sealing effect. In addition, the lip-shaped sealing ring can also elastically deform along with the rotation or axial movement of the rotating shaft 10, so that the influence on the rotation or axial movement process of the rotating shaft 10 can be reduced, and the sealing effect between the rotating shaft 10 and the first sleeve 30 in the movement process can be ensured.
The first sealing ring 32 may be directly clamped between the inner peripheral wall of the first sleeve 30 and the outer peripheral wall of the rotating shaft 10, or may be fixed on the first sleeve 30 by a limiting structure. For example, as shown in fig. 3, a sealing groove 33 is formed in an inner peripheral wall of the first sleeve 30, the sealing groove 33 extends along a circumferential direction of the rotating shaft 10, and the first sealing ring 32 is partially embedded in the sealing groove 33. The sealing groove 33 can fix the first sealing ring 32 and the first sleeve 30, so that when the rotating shaft 10 moves axially relative to the first sleeve 30, the first sealing ring 32 is prevented from being carried out of the first sleeve 30 by the rotating shaft 10 or from being displaced in the first sleeve 30, and the installation stability of the first sealing ring 32 can be improved.
Illustratively, as shown in fig. 3, a boss 12 is formed on a peripheral wall of the rotating shaft 10 near one end of the grinding disc 60, the boss 12 extends along a circumferential direction of the rotating shaft 10, and the grinding disc 60 is connected to a side of the boss 12 facing away from the first sleeve 30; an active area 13 is formed between the boss 12 and the flat key 20, and one end of the first sleeve 30, at which the first sealing ring 32 is installed, can move axially in the active area 13 relative to the rotating shaft 10. The rotating shaft 10 can move axially until the boss 12 abuts against the first sleeve 30 or the flat key 20 abuts against the first sealing ring 32, so that the boss 12 and the first sealing ring 32 can limit the axial displacement of the rotating shaft 10 together; thus, the limit structure of the rotating shaft 10 can be simplified.
For example, as shown in fig. 5 and 6, the grinding disc 60 is provided with a mounting hole 61, and an end of the rotating shaft 10 is fixedly matched with the mounting hole 61; the grinding and cleaning assembly further comprises a second sealing ring 62, wherein the second sealing ring 62 is installed between the grinding disc 60 and the boss 12 and is annularly arranged in the installation hole 61.
The grinding disk 60 is provided with an installation groove on one surface facing the boss 12, and the installation groove is located on the outer peripheral side of the second seal ring 62. The surface of the boss 12 facing the grinding disc 60 is provided with an assembly groove, and the position of the assembly groove corresponds to the position of the installation groove. The mounting groove and the mounting groove can be fixedly matched through a fixing pin to realize the relative fixation of the grinding disc 60 and the boss 12.
