Description

Technical Field

[0001] The present invention relates to the technical field of mechanical arms, in particular to a mechanical arm used for trimming and chamfering quartz crucibles. Background Art

[0002] A quartz crucible is a container formed from high-purity quartz sand through a mold and then produced at high temperatures using an electric arc method. It offers advantages such as high purity, strong heat resistance, large dimensions, high precision, excellent thermal insulation, energy conservation, and stable quality. It is a key, disposable consumable item used to hold molten silicon during the single crystal silicon ingot drawing process. During the quartz crucible production process, after the crucible blank is formed, the outer edge of the crucible must be trimmed to meet dimensional requirements. This removes any undesirable areas and ensures that the crucible height meets process requirements.

[0003] However, the supporting structure of the existing trimming mechanism is only composed of a supporting shaft and a clamping roller at its end. During the cutting process, the outer edge of the crucible is always in contact with the clamping roller. After the cutting is completed, the crucible cutting waste falls directly on the clamping roller, which is not easy to clean. In addition, the trimming and chamfering mechanism lacks the function of buffering and supporting when cutting the outer edge of the crucible. The stress variation of the contact part between the trimming and chamfering mechanism and the crucible body is large, which can easily damage the outer edge of the crucible and cause edge collapse, resulting in a reduced yield, which has a certain adverse effect on people's use process. In order to solve the shortcomings of the existing technology, we propose a robotic arm for trimming and chamfering quartz crucibles. Summary of the Invention

When clamping the two sides of the quartz crucible body, the right-angle frame will fit the side of the quartz crucible body and automatically rotate. The quartz crucible body is limited by the limiting roller, so that the clamping assembly automatically adapts to quartz crucible bodies of different diameters.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] Example 1, as Figure 1 - Figure 5 As shown, a robotic arm for trimming and chamfering a quartz crucible comprises a trimming and chamfering device 1, a working robotic arm 3 and an inner supporting robotic arm 4. A conveyor belt 2 is fixedly installed on the right side inside the trimming and chamfering device 1, the working robotic arm 3 is slidably installed on the top of the trimming and chamfering device 1, a quartz crucible body 6 is installed inside the working robotic arm 3, and the inner supporting robotic arm 4 is fixedly installed on the left side of the upper end of the trimming and chamfering device 1. The quartz crucible body 6 is transported to the interior of the trimming and chamfering device 1 through the conveyor belt 2, and the quartz crucible body 6 is loaded and unloaded by the working robotic arm 3, thereby realizing automatic loading and unloading of the quartz crucible body 6 and improving the efficiency of trimming and chamfering of the quartz crucible body 6. like Figure 3 - Figure 5As shown, the working robot arm 3 includes an electric walking wheel 31, a hydraulic lifting rod 32, a clamping frame 33 and a clamping assembly 38. The hydraulic lifting rod 32 is fixedly mounted on the top of the electric walking wheel 31, and the bottom of the hydraulic lifting rod 32 is fixedly mounted on the clamping frame 33. A driving assembly 340 is fixedly mounted on the right side of the clamping frame 33. A clamping motor 34 is fixedly mounted on one side of the clamping frame 33. A bidirectional screw 35 is fixedly mounted on the output end of the clamping motor 34. The bidirectional screw 35 is rotatably mounted on the inside of the clamping frame 33. Moving frames 36 are slidably mounted on both ends of the bottom of the clamping frame 33. The tops of the moving frames 36 at both ends are respectively threaded on the outer surfaces of the two ends of the bidirectional screw 35. The lower ends of the outer sides of the moving frames 36 at both ends are fixedly mounted with a rotating motor 37. The output end of the rotating motor 37 is fixedly mounted on the clamping assembly 38. Among them, the clamping assembly 38 includes a side frame 381 and a support shaft 383 fixedly installed on the upper and lower sides of the side frame 381 away from the rotating block 382. The outer surface of the support shaft 383 is rotatably installed with a right-angle frame 384. The right side of the side frame 381 is fixedly installed with a rotating block 382, and the rotating block 382 is connected to the output end of the rotating motor 37. Both ends of the right-angle frame 384 are rotatably installed with limiting rollers 385. The inside of the side frame 381 is fixedly installed with an internal frame 386, and the inside of the internal frame 386 is fixedly installed with an electric telescopic rod 387. One side of the electric telescopic rod 387 is fixedly installed with a first electric suction cup 388.

[0025] By utilizing the interaction between the right-angle frame 384 and the limiting roller 385, when the clamping motor 34 controls the bidirectional screw 35 to rotate, the movable frame 36 moves toward each other, and the clamping assemblies 38 on both sides move toward each other to clamp the two sides of the quartz crucible body 6. At this time, the right-angle frame 384 will fit on the side of the quartz crucible body 6 and automatically rotate, and the quartz crucible body 6 is limited by the limiting roller 385, so that the clamping assembly 38 automatically adapts to quartz crucible bodies 6 of different diameters. Subsequently, the electric telescopic rod 387 pushes the first electric suction cup 388 to fit on both sides of the quartz crucible body 6. The quartz crucible body 6 is adsorbed by the first electric suction cup 388. The first electric suction cup 388 improves the stability of the clamping of the quartz crucible body 6 to prevent the quartz crucible body 6 from falling. The rotating motor 37 can control the clamping assemblies 38 at both ends to rotate synchronously, so that the quartz crucible body 6 is rotated to a horizontal state. The quartz crucible body 6 can be controlled to be in different states by the working robot arm 3, and the quartz crucible body 6 is trimmed and chamfered in a horizontal state to prevent cutting dust and debris from falling into the interior of the quartz crucible body 6, thereby reducing the burden of cleaning.

[0026] like Figure 2As shown, the trimming and chamfering equipment 1 includes a working body 11, a limiting track 12 is fixedly installed on the top of the working body 11, a support frame 13 is fixedly installed on the left side of the bottom of the working body 11, a fixing plate 15 is fixedly installed on the side of the inner part of the working body 11 close to the support frame 13, an electric slide rail 16 is fixedly installed on the top of the fixing plate 15, an electric slide 17 is slidably installed on the top of the electric slide rail 16, a cutting knife 18 is provided on one side of the top of the electric slide 17, and a chamfering knife 19 is provided on the other side of the top of the electric slide 17, and a limiting support device 5 is fixedly installed on the right side of the fixed plate 15.

[0027] The motor inside the electric slide 17 controls the rotation of the threaded rod inside the electric slide 17, so that the electric slide 17 moves left and right on the top of the electric slide rail 16. The cutting knife 18 and the chamfering knife 19 are respectively located on both sides of the bottom of the quartz crucible body 6. The electric slide 17 moves to the right on the top of the electric slide rail 16, and the cutting knife 18 feeds to the right to cut the corners of the quartz crucible body 6. After the cutting is completed, the electric slide 17 moves to the left on the top of the electric slide rail 16, the cutting knife 18 returns, and the chamfering knife 19 feeds to the left to chamfer the corners of the quartz crucible body 6, thereby realizing the cutting and chamfering of the quartz crucible body 6.

[0028] Among them, the electric walking wheel 31 is slidably installed inside the limiting track 12, and a waste box 14 is placed at the bottom of the working body 11, and the waste box 14 is located on the right side of the inner support robot arm 4.

[0029] The waste box 14 is on the right side of the inner support robot arm 4. When the waste cut from the quartz crucible body 6 is sleeved on the outer surface of the fixed frame 411, the unloading motor 426 is used to make the rotating cover 423 drive the fixed frame 411 to tilt, so that the waste is affected by gravity and automatically dumped into the inside of the waste box 14, so that the waste from the quartz crucible body 6 can be recycled and processed.

[0030] Example 2, as Figure 1 - Figure 8 As shown, a robotic arm for trimming and chamfering quartz crucibles, the limiting support device 5 includes a limiting support frame 51, a movable frame 53 and support rollers 54 at both ends of the top of the movable frame 53, both sides of the inside of the limiting support frame 51 are fixedly installed with limiting rods 52, the movable frame 53 is movably sleeved on the outer surface of the limiting rod 52, the movable frame 53 is movably sleeved on the upper end of the limiting support frame 51, the support rollers 54 are rotatably installed on both sides of the top of the movable frame 53, an adjusting screw 56 is rotatably installed in the middle of the limiting support frame 51, an adjusting knob 55 is fixedly installed at the bottom of the adjusting screw 56, and the movable frame 53 is threadedly installed on the outer surface of the adjusting screw 56.

[0031] The support roller 54 is used to limit and support the bottom of the quartz crucible body 6, and the rotation of the adjusting screw 56 is used to adjust the lifting of the movable frame 53, thereby controlling the lifting of the support roller 54. The height of the support roller 54 can be adjusted according to the diameter of the quartz crucible body 6 so that the axis of the quartz crucible body 6 corresponds to the axis of the support plate 41, so that the quartz crucible body 6 can maintain stable rotation.

[0032] Example 3, as Figure 7 - Figure 11 As shown, a robotic arm for trimming and chamfering quartz crucibles, the internal support robotic arm 4 includes a positioning frame 421, a rotating cover 423 and a dust collector 428. The positioning frame 421 is fixedly installed on the left side of the top of the working body 11, and the bottom frames 422 are fixedly installed on both sides of the bottom of the positioning frame 421. The rotating cover 423 is rotatably installed between the bottom frames 422 on both sides. The two ends of the rotating cover 423 are fixedly installed with rotating rods 424, and the rotating rods 424 are rotatably installed inside the bottom frames 422. A feeding motor 426 is fixedly installed on one side of the bottom of the positioning frame 421, and a belt transmission mechanism 425 is provided at the output end of the feeding motor 426. The side of the belt transmission mechanism 425 is fixedly connected to the rotating rod 424 at one end. The bottom of the rotating cover 423 is fixedly connected with a connecting hose 427, and one end of the connecting hose 427 is fixedly connected to the dust collector 428. The dust collector 428 is fixedly installed on the top of the support frame 13.

[0033] The belt transmission mechanism 425 includes two pulleys and belts mounted on the outer surfaces of the two pulleys. The upper pulley is connected to the output end of the unloading motor 426, and the lower pulley is connected to the rotating rod 424 on one side of the rotating cover 423. The belt transmission mechanism 425 is controlled to rotate by the unloading motor 426, so that the rotating cover 423 rotates between the bottom frames 422 on both sides, and then the rotating cover 423 is controlled to rotate, so that the fixed wind cover 42 and the support plate 41 rotate and tilt to a certain angle so that the waste on the outer surface of the fixed frame 411 slides down due to gravity and falls into the interior of the waste box 14, thereby facilitating the collection of waste.

[0034] like Figure 8 As shown, the internal support robotic arm 4 also includes a support plate 41, and a fixed wind hood 42 is fixedly installed on the right side of the support plate 41. The outer surface of the fixed wind hood 42 is provided with multiple ventilation slots 43. The fixed wind hood 42 is rotatably installed inside the rotating cover 423. A circular groove is provided on the left side of the support plate 41, and press switches 414 are provided at both ends of the circular groove.

[0035] like Figure 9 As shown, a fixing frame 411 is fixedly installed on the left side of the support plate 41 , and an embedded groove 412 is provided on the outer surface of both ends of the fixing frame 411 , and a plurality of dust suction ports 413 are provided in the middle of the fixing frame 411 between the embedded grooves 412 at both ends.

[0036] When the vacuum cleaner 428 is working, negative pressure is generated inside the rotating cover 423 through the dust suction port 413 and the ventilation slot 43, so that the air drives the dust into the interior of the fixed frame 411 through the dust suction port 413, and then enters the interior of the vacuum cleaner 428 through the ventilation slot 43 and the rotating cover 423 via the connecting hose 427, thereby absorbing the dust. This improves the working environment for processing the quartz crucible body 6 by removing the dust generated during the trimming and chamfering of the quartz crucible body 6.

[0037] like Figure 7 - Figure 9 As shown, the outer surfaces of the embedded grooves 412 at both ends are fixedly sleeved with ventilation frames 49, and the ventilation frames 49 at both ends are connected to each other. The outer surfaces of the ventilation frames 49 at both ends are fixedly sleeved with air bags 410, and the air bags 410 at both ends are connected through the ventilation frames 49. The right end of the ventilation frame 49 is fixedly installed with a ventilation pipe 47, and the right side of the ventilation pipe 47 is fixedly installed with a fixed sleeve 45. The right end of the fixed sleeve 45 is fixedly installed inside the fixed wind hood 42, and the right side of the fixed wind hood 42 is fixedly installed with a pushing cylinder 44, which is electrically connected to the push switch 414. The interior of the pushing cylinder 44 is provided with a cylinder inner rod 48, which is movably sleeved inside the fixed sleeve 45, and the left side of the cylinder inner rod 48 is fixedly installed with a piston 46, which is movably sleeved inside the fixed sleeve 45.

[0038] The air bags 410 at both ends are used to support the inner part of the edge of the quartz crucible body 6, so that the area between the air bags 410 at both ends is the cutting area of the quartz crucible body 6, thereby preventing the cutting knife 18 from interfering with the inner support robot arm 4 when cutting the edge of the quartz crucible body 6. At the same time, the cutting area is located on the side of the dust suction port 413, which is convenient for the vacuum cleaner 428 to vacuum the cut and chamfered areas of the quartz crucible body 6, thereby absorbing dust.

[0039] like Figure 11 As shown, the drive assembly 340 includes a side frame 341, a side frame 342 is fixedly installed at the lower end of the side frame 341, a telescopic cylinder 345 is fixedly installed on one side of the side frame 342, a hexagonal prism 346 is rotatably installed on one end of the telescopic cylinder 345, a second electric suction cup 347 is fixedly installed on one end of the hexagonal prism 346, a transmission motor 343 is fixedly installed on the top of the side frame 342, a driving pulley 344 is fixedly installed on the output end of the transmission motor 343, a transmission wheel 348 is movably sleeved on the outer surface of the hexagonal prism 346, a through groove corresponding to the hexagonal prism 346 is opened inside the transmission wheel 348, a transmission belt is sleeved on the outer surfaces of the driving pulley 344 and the transmission wheel 348, and the hexagonal prism 346 is movably sleeved on one side of the side frame 342.

[0040] The transmission wheel 348 is provided with a through groove corresponding to the hexagonal prism 346. When the telescopic cylinder 345 is extended, the hexagonal prism 346 and the second electric suction cup 347 are controlled to move, so that the second electric suction cup 347 is attached to the bottom of the quartz crucible body 6 and the bottom of the quartz crucible body 6 is adsorbed by the second electric suction cup 347. The transmission motor 343 controls the driving pulley 344 to drive the transmission wheel 348 to rotate using the transmission belt. The transmission wheel 348 limits the hexagonal prism 346, so that the transmission wheel 348 drives the hexagonal prism 346 to rotate, and then the second electric suction cup 347 drives the quartz crucible body 6 to rotate.

[0041] Among them, the side frame 341 is fixedly installed on the right side of the clamping frame 33, and the axis center of the second electric suction cup 347 corresponds to the axis center of the support plate 41. Since the axis center of the second electric suction cup 347 corresponds to the axis center of the support plate 41, the clamping assembly 38 moves toward each other to clamp the two sides of the quartz crucible body 6, and the quartz crucible body 6 is limited by the limiting roller 385 so that the axis center of the quartz crucible body 6 corresponds to the axis center of the second electric suction cup 347, and the transmission motor 343 controls the drive pulley 344 to rotate, and the transmission belt drives the hexagonal prism 346 to rotate, and then the second electric suction cup 347 drives the quartz crucible body 6 to rotate, so that the cutting knife 18 and the chamfering knife 19 can process the edge of the quartz crucible body 6.

[0042] It should be noted that the present invention is a mechanical arm for trimming and chamfering quartz crucibles. When in use, the conveyor belt 2 transports the quartz crucible body 6 to the side of the working mechanical arm 3. At this time, the electric walking wheel 31 moves inside the limiting track 12, so that the clamping frame 33 moves to the top of the quartz crucible body 6. At this time, the hydraulic lifting rod 32 controls the clamping frame 33 to descend, so that the clamping assembly 38 moves to both sides of the quartz crucible body 6. The clamping motor 34 controls the bidirectional screw 35 to rotate, so that the moving frame 36 moves toward each other. The clamping assemblies 38 on both sides move toward each other to clamp the two sides of the quartz crucible body 6. At this time, the right-angle frame 384 rotates and limits the quartz crucible body 6 through the limiting roller 385, so that the clamping assembly 38 automatically adapts to quartz crucible bodies 6 of different diameters. Subsequently, the electric telescopic rod 387 pushes the first electric suction cup 388 to fit on both sides of the quartz crucible body 6, and the first electric suction cup 388 adsorbs the quartz crucible body 6 to achieve clamping of the quartz crucible body 6; The hydraulic lifting rod 32 contracts, causing the movable frame 36 to drive the quartz crucible body 6 to rise. Subsequently, the rotary motors 37 at both ends synchronously control the rotation of the clamping assembly 38, so that the quartz crucible body 6 inside the clamping assembly 38 rotates to a horizontal state. Subsequently, the telescopic cylinder 345 extends to control the movement of the hexagonal prism 346 and the second electric suction cup 347, so that the second electric suction cup 347 fits the bottom of the quartz crucible body 6 and adsorbs the bottom of the quartz crucible body 6 through the second electric suction cup 347. The electric walking wheel 31 controls the quartz crucible body 6 to move to the side of the inner support robot arm 4. The hydraulic lifting rod 32 extends to control the quartz crucible body 6 inside the clamping assembly 38 to descend, so that the quartz crucible body 6 contacts the support roller 54, then, the electric walking wheel 31 continues to drive the quartz crucible body 6 to move to the side of the support plate 41, so that the edge of the quartz crucible body 6 fits into the annular groove on the side of the support plate 41. At this time, the edge of the quartz crucible body 6 presses the side of the press switch 414, so that the cylinder rod 48 inside the push cylinder 44 is extended, and the piston 46 moves to the left inside the fixed sleeve 45. The gas inside the fixed sleeve 45 passes through the vent pipe 47 and the vent frame 49 and enters the interior of the air bag 410. At this time, the air bags 410 at both ends expand, and the air bags 410 at both ends support the interior of the edge of the quartz crucible body 6, so that the area between the air bags 410 at both ends is the cutting area of the quartz crucible body 6. During processing, the first electric suction cup 388 stops adsorbing both sides of the quartz crucible body 6, and the electric telescopic rod 387 controls the first electric suction cup 388 to retract. At this time, the transmission motor 343 controls the driving pulley 344 to rotate, and through transmission, the transmission wheel 348 drives the hexagonal prism 346 to rotate, and the second electric suction cup 347 drives the quartz crucible body 6 to rotate on the top of the supporting roller 54 and inside the limiting roller 385. At this time, the fixing frame 411 and the fixed wind cover 42 rotate inside the rotating cover 423, and the electric slide 17 moves to the right on the top of the electric slide rail 16, and the cutting knife 18 feeds to the right to cut the corners of the quartz crucible body 6. After the cutting is completed, the electric slide 17 moves to the left on the top of the electric slide rail 16, the cutting knife 18 returns, and the chamfering knife 19 feeds to the left to chamfer the corners of the quartz crucible body 6, thereby achieving edge cutting and chamfering of the quartz crucible body 6; During the trimming and chamfering of the quartz crucible body 6, when the vacuum cleaner 428 is in operation, negative pressure is generated inside the rotating cover 423, causing air to carry dust into the interior of the fixed frame 411 through the dust suction port 413, and then into the interior of the vacuum cleaner 428 through the ventilation slot 43 and the rotating cover 423 via the connecting hose 427, thereby absorbing the dust. After the chamfering is completed, the cylinder 44 is pushed to control the cylinder rod 48 to contract, causing the piston 46 to move to the right, and the gas inside the airbag 410 flows back to the inside of the fixed sleeve 45. At this time, the cut waste is sleeved on the outer surface of the fixed frame 411, and the airbag 410 stops supporting the quartz crucible body 6. The electric walking wheel 31 drives the quartz crucible body 6 to move to the top of the conveyor belt 2, and controls the clamping assembly 38 to rotate through the rotating motor 37, so that the quartz crucible body 6 is in a vertical state. The working robot arm 3 places the quartz crucible body 6 on the top of the conveyor belt 2 to realize the unloading of the quartz crucible body 6; During the process of loading and unloading the quartz crucible body 6 by the working robot arm 3, the unloading motor 426 controls the rotation of the rotating cover 423 through the belt transmission mechanism 425, so that the rotating cover 423 is in an inclined state, so that the waste on the outer surface of the fixed frame 411 falls into the interior of the waste box 14 under the action of gravity for recycling and cleaning.
