Description

Technical Field

[0001] This invention relates to the field of planetary wheel manufacturing technology, specifically a planetary wheel manufacturing apparatus. Background Technology

[0002] As is widely known, a planetary wheel is a fixture used in the polishing processes of various flat surfaces such as glass, lenses, silicon wafers, and hard drives. It is also known as a polishing jig or polishing pad. The manufacturing process of planetary wheels is very sophisticated. Polishing lenses, silicon wafers, and gemstones are all very delicate processes. In production, planetary wheels are mostly manufactured by stamping. After stamping, the planetary wheel needs to undergo surface polishing to meet production requirements.

[0003] For example, the patent with publication number CN219053982U, publication date May 23, 2023, entitled "A Polishing Device for Planetary Gears," discloses a polishing device for planetary gears, relating to the field of planetary gear technology. This utility model includes a worktable, with a mounting plate fixedly connected to the rear of the upper surface of the worktable. A fixing plate is fixedly connected to the side wall of the mounting plate. An electric push-pull rod is fixedly connected to the upper surface of the fixing plate. A connecting block is provided on the lower surface of the fixing plate, and a fixing strip is fixedly connected to the lower surface of the connecting block. A limiting strip is provided on the upper side wall; the polishing cloth is wrapped around the outer surface of the insert, and then the upper end of the insert with the polishing cloth is inserted into the slot. The slot fixes the polishing cloth and the insert. When the extension end of the electric push-pull rod moves downward, it causes the polishing cloth to contact the planetary wheel on the clamping bar. The clamping bar rotates, causing the planetary wheel to rotate. The planetary wheel rotates and rubs against the polishing cloth, thereby achieving the polishing effect. At the same time, the rotation of the planetary wheel allows the polishing cloth to fully contact the surface of the planetary wheel, making the polishing more uniform. No manual polishing is required, saving time and effort.

[0004] In the existing technology, when polishing a planetary wheel, it is necessary to position the planetary wheel. Since most planetary wheels have gears on their edges and are relatively thin, vacuum chucks are mostly used to position the planetary wheel. However, existing vacuum chucks are set in fixed positions and can only be used to position a single type of planetary wheel, and cannot be adapted to most types of planetary wheels.

DETAILED DESCRIPTION

[0032] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0033] In the embodiments of the present application, the orientation words "center", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "transverse", and the like indicated by the orientation or position relationship based on the orientation or position relationship shown in the drawings are for the convenience of description of the present application and simplification of the description, and are not indicative or suggestive of the devices or elements indicated having a specific orientation, being constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0034] As Figures 1 to 12 shown, the star wheel manufacturing device provided by the embodiment of the present application comprises a box 1, an automatic scanning light mechanism and a positioning unit arranged on the box 1, the positioning unit comprises a positioning plate 2, a plurality of vacuum chucks 3 are arranged on the positioning plate 2, each vacuum chuck 3 is movably connected to the positioning plate 2, and the vacuum chucks 3 are driven to be capable of being adsorbed on different parts of a star wheel.

[0035] Specifically, the automatic polishing mechanism is an apparatus capable of polishing the star wheel. After stamping, the star wheel surface will have a few flaws that need to be polished to meet the production requirements. The automatic polishing mechanism is a prior art, and the specific structure is not described in detail. When the star wheel is polished, the vacuum chuck 3 is driven to move to the appropriate adsorption position (i.e. the position without stamping perforation on the star wheel) on the positioning plate 2. The adsorption position of the star wheel is aligned with the vacuum chuck 3. The star wheel can be placed manually or by existing technology (such as a mechanical hand, a mechanical arm, etc.). The adsorption function of the vacuum chuck 3 is started (i.e. the adsorption position of the vacuum chuck 3 and the star wheel is vacuumized, which is a prior art and not described in detail). The vacuum chuck 3 can stably position the star wheel, and the adsorption positioning of the vacuum chuck 3 can effectively reduce the damage of the star wheel during positioning. The automatic polishing mechanism is started, and the star wheel is polished by the automatic polishing mechanism to obtain a polished star wheel. This is a prior art and not described in detail. During the polishing of the star wheel, the star wheel needs to be positioned. Since the edges of the star wheel mostly have gears and the thickness of the star wheel is relatively thin, the vacuum chuck 3 is mostly used for positioning the star wheel. The existing vacuum chuck 3 is set in a fixed position and can only position a single type of star wheel. It cannot adapt to most types of star wheels. In the present embodiment, the vacuum chuck 3 is driven to move to the adsorption position, and the star wheel is placed on the vacuum chuck 3. The vacuum chuck 3 adsorbs and positions the star wheel. The movement of the vacuum chuck 3 enables the vacuum chucks 3 on the positioning unit to position various types of star wheels, and positioning the star wheel by the vacuum chuck 3 can effectively reduce the probability of breaking (moving or deforming) during positioning.

[0036] Further, six sliding grooves 4 are uniformly arranged on the top surface of the positioning plate 2 along the circumferential direction, and a sliding plate 5 is arranged in each of the six sliding grooves 4. A through slot 6 is arranged on each of the six sliding plates 5. Two adjacent through slots 6 are connected by a bent rod 7, that is, the two ends of each bent rod 7 pass through one through slot 6, and each through slot 6 is simultaneously passed through by two bent rods 7 from both sides. The two bent rods 7 in the same through slot 6 slide with each other. The outer wall of one of the sliding plates 5 is connected with the output end of the first driving member 8, and the first driving member 8 is installed on the positioning plate 2. The vacuum chuck 3 is arranged on each of the sliding plates 5.

[0037] Specifically, when the position of the vacuum chuck 3 on the positioning plate 2 needs to be adjusted (i.e. when the vacuum chuck 3 needs to be adjusted to a suitable suction position), the first driving member 8 (which can be a linear reciprocating mechanism and device, such as a pneumatic cylinder, an electric push rod, etc.) is started to drive a sliding plate 5 to slide in the sliding groove 4. The sliding plates 5 are connected by the through slot 6 and the bent rod 7 (the bent rod 7 includes two bent arms, the angle between the two bent arms is 120 degrees, and the middle angle position of the bent rod 7 is the connection position, which is used to connect the two bent arms (i.e. the two linear parts of the bent rod 7), the linear directions of the two bent arms and the corresponding sliding grooves 4 where the sliding plates 5 are installed are perpendicular to each other, and the two bent arms are arranged in an up-down staggered manner, i.e. one bent arm is located at the top of the angle position and the other bent arm is located at the bottom of the angle position). When the sliding plate 5 slides in the sliding groove 4, the sliding plate 5 connected with the first driving member 8 drives the bent rod 7 to move, and the bent rod 7 drives the other sliding plates 5 to slide synchronously in the sliding groove 4 through the through slot 6, i.e. the six bent rods 7 and the six sliding plates 5 slide synchronously, until the sliding plate 5 drives the vacuum chuck 3 to slide to the suitable suction position.

[0038] Further, each of the three sliding plates 5 spaced apart on the positioning plate 2 is provided with a supporting block 9, each of the three supporting blocks 9 is provided with a vacuum chuck 3, each of the remaining three sliding plates 5 spaced apart on the positioning plate 2 is provided with a block 10, i.e. the blocks 10 and the supporting blocks 9 are spaced apart, two blocks 10 are provided with a supporting block 9, and two supporting blocks 9 are provided with a block 10, each of the three blocks 10 is rotatably provided with an adjusting round rod 11, each of the three adjusting round rods 11 is provided at the top end with a supporting plate 12, each of the supporting plates 12 is symmetrically provided with two vacuum chucks 3, each of the three adjusting round rods 11 is provided between the block 10 and the supporting plate 12 with a driven gear 13, each of the three supporting plates 12 is provided with a driving frame 14 on the side edge of the positioning plate 2, each of the three driving frames 14 is provided with a rack 15 on the side wall, and the rack 15 and the driven gear 13 are meshed with each other.

[0039] Specifically, when the sliding plates 5 slide in the sliding grooves 4, (1) three of the sliding plates 5 drive the supporting blocks 9 to move, and the supporting blocks 9 drive the vacuum suction cups 3 to slide to appropriate suction positions, so that the vacuum suction cups 3 are suctioned to the star wheels; (2) the other three of the sliding plates 5 drive the square blocks 10 to move, and the square blocks 10 drive the adjusting round rods 11 to move, and the adjusting round rods 11 drive the supporting plates 12 to move. When the adjusting round rods 11 drive the driven gears 13 to move to a position where the driven gears 13 are meshed with the racks 15, the driven gears 13 are rotated under the meshing action of the racks 15, the driven gears 13 drive the adjusting round rods 11 to rotate by a certain angle, the adjusting round rods 11 drive the supporting plates 12 to rotate by a certain angle, one of the vacuum suction cups 3 on the supporting plate 12 coincides with the axis of the adjusting round rod 11, and the other of the vacuum suction cups 3 on the supporting plate 12 is arranged at the end of the adjusting round rod 11. When the supporting plate 12 rotates, the position of one of the vacuum suction cups 3 moves with the position of the adjusting round rod 11, and the position of the other of the vacuum suction cups 3 rotates with the rotation of the supporting plate 12, until the two vacuum suction cups 3 on the supporting plate 12 move to appropriate suction positions. The rotation angle of the supporting plate 12 is at most 180 degrees. As long as at least one (preferably two) of the vacuum suction cups 3 on the supporting plate 12 can move to appropriate suction positions of the star wheels in the rotation stroke of the supporting plate 12, the sliding plates 5 can stop moving. Thus, one of the vacuum suction cups 3 moves in a large range during the movement of the sliding plates 5, and realizes secondary movement in the range of primary movement, so that the vacuum suction cups 3 can be suctioned to most of the star wheels. The two vacuum suction cups 3 on the same supporting plate 12 and the vacuum suction cup 3 on the same supporting block 9 can all move to appropriate suction positions. The star wheels can be stably positioned. The star wheels are positioned by the suction of the multiple-point distributed vacuum suction cups 3, so that the risk of damage of the star wheels during machining can be effectively prevented.

[0040] In another embodiment of the present application, the vacuum chuck 3 comprises a driven sealing rod 28, the middle part of the vacuum chuck 3 is provided with an air inlet channel 29, the inner wall of the air inlet channel 29 is provided with a blocking groove 30, the driven sealing rod 28 is slidably installed in the air inlet channel 29, the driven sealing rod 28 is provided with a blocking ring 31, the blocking ring 31 is slidably installed in the blocking groove 30, the top end of the blocking ring 31 and the blocking groove 30 is tightly sealed, the bottom end of the blocking ring 31 and the bottom end of the blocking groove 30 are connected by a first elastic element 32, specifically, after the star wheel is placed on the vacuum chuck 3, the star wheel extrudes the vacuum chuck 3, so that the vacuum chuck 3 is in a flat state (that is, the top end of the vacuum chuck 3 is attached to the star wheel), the star wheel slides the driven sealing rod 28 to one end of the air inlet channel 29, because the driven sealing rod 28 is not tightly attached to the inner wall of the air inlet channel 29, only two sliding elements are symmetrically arranged on the side wall of the driven sealing rod 28, the sliding elements are slidably arranged on the inner wall of the air inlet channel 29, the sliding elements will not block the air inlet channel 29, so that the driven sealing rod 28 drives the blocking ring 31 to slide to the bottom end of the blocking groove 30, the blocking ring 31 extrudes the first elastic element 32 (the first elastic element 32 is an element that can be stretched and reset, preferably a spring), so that the first elastic element 32 is in a compressed state, so that the blocking ring 31 no longer blocks the air inlet channel 29, so that the air inlet channel 29 can flow, at this time, the suction pump is started to perform vacuumizing operation on the vacuum chuck 3, so that the vacuum chuck 3 forms a negative pressure and performs adsorption positioning operation on the star wheel, which is a common knowledge in the art and will not be described here. However, due to different models of star wheels, the vacuum chuck 3 may not be in contact with the surface of the star wheel, so that the driven sealing rod 28 will not slide into the air inlet channel 29 without the extrusion of the star wheel, so that the blocking ring 31 blocks the air inlet channel 29 under the elastic force of the first elastic element 32 (that is, the elastic force provided by the first elastic element 32 for the blocking ring 31 is greater than the adsorption force generated when the suction pump performs vacuum adsorption on the vacuum chuck 3, so that the blocking ring 31 will not open the air inlet channel 29 under the adsorption force generated when the vacuum chuck 3 performs vacuum adsorption). When the above-mentioned star wheel is placed on the vacuum chuck 3, the weight of the star wheel causes the star wheel to extrude the first elastic element 32 through the driven sealing rod 28 and the blocking ring 31, so that the blocking ring 31 opens the air inlet channel 29 and does not affect the vacuumizing operation of the suction pump on other vacuum chucks 3.

[0041] In another embodiment of the present invention, the vacuum suction cup 3 is divided into a conical portion 311 and a rod portion 312. An auxiliary annular groove 33 is provided at the top of the rod portion 312 of the vacuum suction cup 3. Multiple through holes 36 communicating with the air intake channel 29 are evenly arranged on the auxiliary annular groove 33. A sliding ring 34 is provided at the bottom of the conical portion 311 of the vacuum suction cup 3. The sliding ring 34 is slidably and sealingly installed in the auxiliary annular groove 33. Both the conical portion 311 and the sliding ring 34 of the vacuum suction cup 3 are made of flexible materials (such as rubber), while the rod portion 312 of the vacuum suction cup 3 can be made of rigid materials. The bottom end of the sliding ring 34 and the bottom end of the auxiliary annular groove 33 are connected by a second elastic member 35. Specifically... After the planetary wheel is placed on the vacuum suction cup 3, the planetary wheel compresses the vacuum suction cup 3. Since the conical part 311 of the vacuum suction cup 3 is made of flexible material, the conical part 311 of the vacuum suction cup 3 can more easily adhere to the planetary wheel, and the conical part 311 of the vacuum suction cup 3 will not damage the planetary wheel when adsorbing and positioning it. When the planetary wheel pushes the driven sealing rod 28 into the air intake channel 29, the conical part 311 of the vacuum suction cup 3 drives the sliding ring 34 to slide into one end of the auxiliary ring groove 33, so that the second elastic element 35 (the second elastic element 35 is a component that can extend and retract and reset, preferably a spring) is in a compressed state, so that the sliding ring 34 slides completely into the auxiliary ring groove 33. Inside the groove 33, the sliding ring 34 on the vacuum chuck 3 will not affect the processing of the planetary wheel (that is, the flexible part of the sliding ring 34 on the vacuum chuck 3 will not swing during the processing of the planetary wheel, thus affecting the processing of the planetary wheel), improving the stability of the vacuum chuck 3's adsorption and positioning of the planetary wheel. At this time, due to the presence of the second elastic element 35 providing elasticity to the sliding ring 34, but because the auxiliary ring groove 33 is provided with a through hole 36 between it and the air inlet channel 29, and the sliding ring 34 and the auxiliary ring groove 33 are dynamically sealed, when the suction pump performs vacuuming operation on the vacuum chuck 3, the vacuuming force acts on the sliding ring 34 through the through hole 36 and the auxiliary ring groove 33, which is the sliding rod 34. An adsorption force is provided to move towards the bottom of the auxiliary ring groove 33. This adsorption force can counteract the rebound force provided by the second elastic element 35 to the sliding ring 34, so that when the driven sealing rod 28 is subjected to the weight of the planetary wheel, the sealing ring 31 can open the air intake channel 29, allowing the vacuum suction cup 3 to perform adsorption and positioning operations on the planetary wheel. When the planetary wheel is not in contact with the driven sealing rod 28, the sealing ring 31 will not open the air intake channel 29, thus not affecting the normal operation of the suction pump and other vacuum suction cups 3. That is, when the sealing ring 31 opens the air intake channel 29, and the vacuum suction cup 3 does not adsorb the planetary wheel, the air intake channel 29 will always be in the open state, thus affecting the adsorption and positioning of other vacuum suction cups 3.

[0042] In still another embodiment of the present application, the positioning plate 2 is provided with a through groove 16 between two adjacent sliding grooves 4, the linear direction of the through groove 16 coincides with the angle bisector of the included angle between the two adjacent sliding grooves 4, a limiting round rod 17 is arranged at the bottom end of the bending angle of each of the six bending rods 7, the six limiting round rods 17 are slidably arranged in the corresponding through grooves 16, a supporting round rod 18 is arranged at the top end of the bending angle of each of the six bending rods 7, and two auxiliary rods 19 are arranged at the bottom end of each of the six limiting round rods 17.

[0043] Specifically, when the sliding plate 5 slides in the sliding groove 4, the bending rod 7 moves synchronously with the sliding plate 5, because the limiting round rod 17 is arranged at the bending angle of the bending rod 7 and the through groove 16 is arranged on the angle bisector of the included angle between the two adjacent sliding grooves 4, the limiting round rod 17 slides synchronously in the through groove 16 when the bending rod 7 moves synchronously, the supporting round rod 18 moves synchronously with the limiting round rod 17, and the supporting round rod 18 supports the wandering star wheel after the vacuum suction disc 3 on the supporting plate 12 and the vacuum suction disc 3 on the supporting block 9 adsorb and position the wandering star wheel, so that the supporting round rod 18 supports the wandering star wheel. Because the supporting force of the vacuum suction disc 3 on the wandering star wheel is unstable, the supporting round rod 18 stably supports the wandering star wheel, preventing the wandering star wheel from being damaged when the automatic polishing mechanism works on the wandering star wheel. When the bending rod 7 moves synchronously, the limiting round rod 17 slides synchronously in the through groove 16, and the vacuum suction disc 3 at the bottom end of the limiting round rod 17 can also adsorb and position another wandering star wheel on the other side, that is, theoretically, by reasonably configuring the shape, two wandering star wheels can be adsorbed and positioned at the same time, and the other wandering star wheel can be supported by the auxiliary rod 19. The automatic polishing mechanism on the same side of the auxiliary rod 19 on the box body 1 can also be arranged, and the automatic polishing mechanism can polish the wandering star wheel at the bottom end of the limiting round rod 17 after the vacuum suction disc 3 at the bottom end of the limiting round rod 17 adsorbs the wandering star wheel, thereby improving the production efficiency of the wandering star wheel. The limiting round rod 17 and the sliding plate 5 on the same positioning unit can synchronously adsorb and position the wandering star wheels on both sides of the positioning plate 2, so that the wandering star wheels adsorbed on both sides of the positioning plate 2 work synchronously, thereby effectively improving the processing efficiency of the wandering star wheel. In this embodiment, the vacuum suction disc 3 at the bottom end of the limiting round rod 17 is not provided with the driven sealing rod 28 and the sliding ring 34.

[0044] In still another embodiment of the present application, the side wall of the positioning plate 2 is provided with a rotary positioning unit for driving the positioning plate 2 to rotate 180 degrees and positioning, which comprises a flat plate 20 and a rotating shaft 21, two flat plates 20 are symmetrically installed between the side walls on both sides of the box 1, two rotating shafts 21 are symmetrically installed on the side walls of the positioning plate 2, and the two rotating shafts 21 are respectively rotatably installed on the corresponding flat plates 20, one of the rotating shafts 21 penetrates through the flat plate 20 and is provided with a half-face gear 22, one face of the half-face gear 22 is a gear face, the other face of the half-face gear 22 is a semicircular face, the top end and the bottom end of the half-face gear 22 are both flat faces, a slide rail 23 is installed between the side walls on the same side of the box 1 as the half-face gear 22, a driving plate 24 is slidably installed on the slide rail 23, the two ends of the driving plate 24 are L-shaped faces, and the L-shaped faces and the flat faces of the half-face gear 22 are slidably installed with each other, a plurality of transmission round rods 25 are uniformly arranged in the middle of the driving plate 24, and the toothed portions on the plurality of transmission round rods 25 and the gear face of the half-face gear 22 are meshed with each other so that the half-face gear 22 can rotate 180 degrees under the driving of the transmission round rods 25, a transmission plate 26 is installed on the driving plate 24, and the transmission plate 26 and the side wall of the box 1 are connected through a second driving element 27.

[0045] Specifically, when the positioning plate 2 has two star wheels adsorbed on both sides, the automatic polishing mechanism is needed to polish the star wheels, and the positioning plate 2 needs to be rotated by 180 degrees so that the polished star wheels are aligned with the automatic polishing mechanism. The initial position of the driving plate 24 is that the L-shaped surface of the driving plate 24 and the bottom surface of the half-face gear 22 are parallel to each other, so that the L-shaped surface of the driving plate 24 positions the half-face gear 22 to prevent the half-face gear 22 from rotating. The second driving member 27 (which can be a linear reciprocating mechanism and device, such as a pneumatic cylinder, an electric push rod, etc.) is started to drive the transmission plate 26 to move, and the transmission plate 26 drives the driving plate 24 to slide on the slide rail 23. The L-shaped surface on one side of the transmission plate 26 slides away from the bottom surface of the half-face gear 22, so that the L-shaped surface on one side of the transmission plate 26 no longer positions the half-face gear 22. When the transmission round rod 25 on the driving plate 24 slides to the position where the gear surface on the half-face gear 22 is engaged, the driving plate 24 is continuously driven to slide on the slide rail 23, so that the transmission round rod 25 drives the half-face gear 22 to rotate by 180 degrees, until the L-shaped surface on the other side of the transmission plate 26 is parallel to and attached to the top surface of the half-face gear 22, so that the L-shaped surface on the other side of the transmission plate 26 positions the half-face gear 22 to prevent the half-face gear 22 from rotating. When the half-face gear 22 rotates by 180 degrees, the half-face gear 22 drives the rotating shaft 21 to rotate by 180 degrees, and the rotating shaft 21 drives the positioning plate 2 to rotate by 180 degrees, so that the positioning plate 2 drives the positions of the two star wheels adsorbed thereon to be exchanged, so that the star wheels are polished and polished. The rotating positioning unit can drive the two star wheels on the positioning plate 2 to rotate by 180 degrees and be positioned, which can improve the processing efficiency of the star wheels.

[0046] The foregoing merely describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present application.
