Description

Technical Field

[0001] The present invention relates to the technical field of crystal rod transportation, and in particular to a multifunctional self-adaptive crystal rod taking attachment for a crystal rod transportation AGV. Background Art

[0002] A crystal rod is a common solid substance, usually in the shape of a rod, made of a single crystal material, and has a highly ordered crystal structure. A crystal rod can be made of a variety of different materials, such as crystalline silicon, cadmium selenide, titanium crystal rods, etc. These materials undergo precise furnace melting, crystal growth and processing to form a rod-shaped object with a single crystal structure. The maximum weight of a crystal rod is 1000kg, the diameter of the crystal rod is 250mm to 310mm, and the longest length of the crystal rod is 6000mm. The single crystal silicon generated after high-temperature melting and cooling in the furnace body is pulled out from the furnace body discharge port in the form of a crystal rod and needs to be transported to a pallet truck.

[0003] When the existing crystal rod transfer attachment clamps the crystal rod, its clamping position is fixed, resulting in poor stability when clamping a longer crystal rod. When the crystal rod is pulled out of the furnace body, the crystal rod will shake, making it difficult to control its falling position, affecting the transfer of the crystal rod.

[0004] In view of the above problems, the present invention provides a multifunctional adaptive crystal rod retrieval attachment for a crystal rod transfer AGV to solve the above problems. Summary of the invention

[0039] Reference Figure 1-Figure 4 The present invention provides a technical solution: a multifunctional adaptive crystal rod taking attachment for crystal rod transport AGV, comprising:

[0040] AGV body 1;

[0041] A lifting device 2, fixed on the AGV body 1;

[0042] A rotating device 3 is fixed at the output end of the lifting device 2, and a rotating motor is fixed inside the rotating device 3;

[0043] The fixture lifting device 4 is rotatably arranged on the rotating device 3 using a rotating plate 41 and is driven to rotate by the rotating motor;

[0044] A lifting plate 5 is fixed to the bottom of the fixture lifting device 4;

[0045] A clamping assembly 6, fixed to the output end of the clamp lifting device 4;

[0046] A shearing device 7 is fixed on the upper end surface of the clamping assembly 6;

[0047] The clamping assembly 6 comprises a sliding member 61 , an adjusting motor 62 is fixed to the bottom of the sliding member 61 , a threaded rod 63 is fixed to the output end of the adjusting motor 62 , two sliding blocks 66 are symmetrically arranged on the threaded rod 63 , and a correction assembly 67 is fixed to the sliding block 66 .

[0048] It should be noted that when picking up the crystal rod, the adjustment motor 62 controls the movement speed of the correction component 67 to be the same as the speed at which the crystal rod is pulled out of the furnace body, thereby continuously correcting the crystal rod without hindering the pulling out of the crystal rod, thereby improving the stability of crystal rod picking.

[0049] In this embodiment, a partition seat 64 is fixed in the middle position of the sliding member 61, the threaded rod 63 is rotatably arranged in the partition seat 64, and the threaded rod 63 is separated by the partition seat 64, and the threaded rods 63 on both sides of the partition seat 64 have opposite rotation directions.

[0050] That is to say, the movement directions of the two correcting components 67 are opposite. When the correcting component 67 located at the upper side completes the correction, the correcting component 67 located at the lower side takes over to perform continuous correction.

[0051] As a preferred embodiment, the two sliding blocks 66 are respectively located on the threaded rods 63 with opposite rotation directions, and the two sliding blocks 66 are both guided and limited by guide columns 65, and clamping motors are fixed in the two sliding blocks 66.

[0052] As a preferred embodiment, the deviation correction component 67 includes:

[0053] A fixing frame 671, fixed on the sliding block 66;

[0054] The limiting posts 673 are configured as four and symmetrically fixed on the fixing frame 671;

[0055] The clamping frame 672 is configured as two, symmetrically and slidably disposed on the limiting column 673;

[0056] The rack 674 is fixed on one side of the two clamping frames 672 close to each other;

[0057] A gear 675 is fixed on the output shaft of the clamping motor and meshes with the two racks 674;

[0058] A sliding column 677, fixed at the middle position of the fixing frame 671;

[0059] The lifting assembly 676 is configured as two, symmetrically and slidably arranged on the sliding column 677 and the limiting column 673.

[0060] As a preferred embodiment, one end of the lifting assembly 676 is located in the clamping frame 672 , and a correction spring 678 is provided between the lifting assembly 676 and the clamping frame 672 .

[0061] During correction, the lifting components 676 are moved closer to each other by the clamping motor until they contact the outer wall of the crystal rod. At this time, the correction spring 678 is in an unstressed state. When the crystal rod shakes, the correction spring 678 can flexibly buffer the crystal rod, thereby reducing the shaking amplitude of the crystal rod.

[0062] As a preferred embodiment, the lifting assembly 676 includes:

[0063] The clamping plate 6761 is slidably disposed on the sliding column 677 and the limiting column 673;

[0064] A sliding compartment 6762 is provided on the end surface of the clamping plate 6761 close to the lifting plate 5;

[0065] An auxiliary lifting plate 6763 is slidably disposed in the sliding compartment 6762;

[0066] The telescopic columns 6764 are configured as a plurality, fixed in the sliding compartment 6762 at equal intervals, and slidably connected to the auxiliary lifting plate 6763;

[0067] The pressing spring 6765 is sleeved on the telescopic column 6764.

[0068] That is to say, before the deviation is corrected, the bottom of the crystal rod is first lifted by the auxiliary lifting plate 6763, and then the two clamping plates 6761 are moved closer to each other through the clamping motor to facilitate the lifting of the crystal rod.

[0069] As a preferred embodiment, the clamping plates 6761 in the two lifting assemblies 676 are provided with arc-shaped clamping surfaces on the sides close to each other, and the initial position of the auxiliary lifting plates 6763 is to extend from the arc-shaped clamping surfaces.

[0070] Among them, when clamping the crystal rod, the auxiliary supporting plates 6763 are moved away from each other so that the crystal rod can fall, and the clamping motor is used to make the clamping plates 6761 approach each other to complete the clamping. At the same time, the auxiliary supporting plates 6763 slide and retract, and when clamping, the correction spring 678 needs to be compressed to ensure the stability of clamping, and the distance between the two correction components 67 can be controlled by adjusting the motor 62, so that the crystal rods of different lengths can be clamped at different positions, thereby improving the stability of clamping.

[0071] Specifically, first, the AGV body 1 moves to the discharge port of the furnace body, and then the clamping assembly 6 is raised by the lifting device 2 and the clamp lifting device 4, so that it is close to the discharge port of the furnace body, which is convenient for protecting and picking up the crystal rod, and then the correcting assemblies 67 are moved away from each other by adjusting the motor 62, so that the correcting assembly 67 located above is close to the discharge port of the furnace body, which is convenient for directly picking up and correcting the crystal rod, and then the bottom of the crystal rod is lifted by the auxiliary lifting plate 6763 above, and corrected by the correcting assembly 67, and then the furnace body pulls out the crystal rod while the adjusting motor 62 controls the correcting assembly 67 to move synchronously, so as to perform continuous correction and lifting, which increases the stability of picking up the crystal rod, and when the two correcting assemblies 67 are completely close, the furnace body stops pulling out the crystal rod, and the correcting assembly located above The clamping plates 6761 in 67 move away from each other, causing the auxiliary lifting plate 6763 to detach from the crystal rod, and then the furnace body continues to pull out the crystal rod, so that the correcting assembly 67 located below performs corrective lifting, and then the correcting assembly 67 located below moves toward the lifting plate 5. When the two correcting assemblies 67 are in the maximum state of being away from each other, the correcting and auxiliary lifting are completed. At this time, the auxiliary lifting plate 6763 located below also detaches from the crystal rod, and then the crystal rod is lifted by the lifting plate 5. At this time, the distance between the two correcting assemblies 67 is controlled by adjusting the motor 62, so that different positions are clamped according to different lengths of crystal rods, thereby improving the stability of clamping, completing the clamping operation, and then cutting it through the shearing device 7. Finally, the crystal rod is transported to the storage position, and the crystal rod is placed horizontally through the rotating device 3 to complete the crystal rod transfer.

[0072] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
