DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] This utility model provides two technical solutions:

[0027] Figure 1-Figure 5The first embodiment is shown: a multi-crucible crystal growth furnace, comprising a base 1, a furnace body mechanism 2 is provided on the top of the base 1 for heating the crucible, and a material changing mechanism 3 is provided on the right side of the furnace body mechanism 2 at the top of the base 1 for loading or unloading the crucible. The material changing mechanism 3 includes:

[0028] The replacement assembly 31 is disposed on the top of the base 1 and includes an electric push rod 311 fixedly mounted on the top of the base 1. The telescopic end of the electric push rod 311 is fixedly mounted to a fixing bracket 312. A first motor 313 is fixedly mounted to the inner top of the fixing bracket 312. The output end of the first motor 313 movably passes through the inner top of the fixing bracket 312 and extends upward. A metal replacement plate 314 is fixedly mounted on the output end of the first motor 313. The outer surface of the metal replacement plate 314 is symmetrically provided with a slot 315.

[0029] The placement component 32 is arranged on the top of the base 1 .

[0030] The top of the base 1 is fixedly installed with a mounting bracket 11 near the left side, and the top of the mounting bracket 11 is fixedly installed with an electric telescopic rod 12. The telescopic end of the electric telescopic rod 12 movably passes through the top of the mounting bracket 11 and extends to the bottom, and the upper cylinder 221 and the lower cylinder 211 are separated or closed by the electric telescopic rod 12. The placement component 32 includes a support bracket 321 fixedly installed on the top of the base 1 at the right side of the electric push rod 311, and a second motor 322 is fixedly installed on the inner top of the support bracket 321. The output shaft end of the second motor 322 movably passes through the inner top of the support bracket 321 and extends upward. A turntable 323 is fixedly installed on the output shaft end of the second motor 322. By starting the second motor 322, the turntable 323 is driven to rotate, thereby driving the outer metal circular plate 325 to rotate. The top of the turntable 323 is equidistantly fixed Eight support rods 324 are fixedly installed, and the outer surface of the support rod 324 is L-shaped and bent near the top. The L-shaped bending setting on the support rod 324 mainly prevents interference during the rotation of the metal replacement plate 314. An outer metal circular plate 325 is fixedly installed on the top of the support rod 324, and the outer metal circular plate 325 and the magnetic crucible holder 4 can be attracted to each other by magnetic force. The magnetic crucible holder 4 is placed on the top of the inner metal circular plate 218 and the outer metal circular plate 325. The magnetic crucible holder 4 is used to place the crucible, and the bottom of the magnetic crucible holder 4 is made of magnetic material, which can be adsorbed with the inner metal circular plate 218, the outer metal circular plate 325 and the metal replacement plate 314, thereby ensuring the stability of the magnetic crucible holder 4 and preventing it from falling. At the same time, the interior of the magnetic crucible holder 4 is consistent with the shape of the crucible, which is convenient for placing the crucible.

[0031] Figure 1-Figure 5The second embodiment is shown, and its main difference from the first embodiment is that the furnace body mechanism 2 includes a rotating component 21, which is arranged at the top of the base 1, and the rotating component 21 includes a lower cylinder 211 fixedly mounted on the top of the base 1, and the lower cylinder 211 is arranged between the electric push rod 311 and the mounting frame 11, a heating component 22, and the heating component 22 includes an upper cylinder 221 fixedly mounted on the telescopic end of the electric telescopic rod 12, and two groups of heating rods 222 are arranged on the inner top of the upper cylinder 221. The heating rods 222 are provided with two circles, the inner circle is surrounded by an inner circle composed of multiple inner metal circular plates 218, and the outer circle is surrounded by an outer circle of the inner metal circular plates 218. The bottom of the upper cylinder 221 contacts the top of the lower cylinder 211, and a driving motor 212 is fixedly mounted on the bottom of the lower cylinder 211. The output shaft end of the driving motor 212 movably passes through the bottom of the lower cylinder 211 and extends to the inside, and the output of the driving motor 212 A turntable 213 is fixedly installed at the end of the output shaft, and the turntable 213 is driven to rotate by starting the driving motor 212. A support ring 214 is fixedly installed on the inner wall of the lower cylinder 211, and the top surface of the support ring 214 contacts the bottom surface of the turntable 213. A gear ring 215 is fixedly installed on the inner wall of the lower cylinder 211 below the support ring 214. The teeth on the gear ring 215 are equidistantly meshed with eight gears 216. The end of the gear 216 is fixedly installed with a support shaft 217. The outer surface of the support shaft 217 movably passes through the bottom surface of the turntable 213 and extends upward, and the surface of the support shaft 217 is concavely bent near the top. The concave bending setting on the support shaft 217 mainly prevents interference during the rotation of the metal replacement plate 314. The top of the support shaft 217 is fixedly installed with an inner metal circular plate 218, and the inner metal circular plate 218 and the magnetic crucible holder 4 can be attracted to each other by magnetic force.

[0032] By starting the drive motor 212 to drive the turntable 213 to rotate, the inner metal circular plate 218 is rotated, so that the crucible is heated evenly. When the inner metal circular plate 218 rotates around the male axis, the gear 216 and the ring gear 215 are engaged, so that the inner metal circular plate 218 simultaneously rotates around the support shaft 217 as the axis. Therefore, the crucible is heated evenly by the coordinated action of the revolution and rotation.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] When in use, the magnetic crucible holder 4 is used to place the crucible. By connecting the power supply of the heating rod 222, the crucible on the magnetic crucible holder 4 on the inner metal circular plate 218 is heated. By starting the drive motor 212 to drive the turntable 213 to rotate, the inner metal circular plate 218 is rotated, so that the crucible is heated evenly. When the inner metal circular plate 218 rotates around the male axis, the gear 216 and the gear ring 215 are engaged, so that the inner metal circular plate 218 rotates with the supporting shaft 217 as the axis. As a result, the crucible is heated evenly under the coordinated action of revolution and rotation. When the crucible needs to be taken out, The upper cylinder 221 is pulled up by the electric telescopic rod 12, and then the electric push rod 311 is started to make the height of the metal replacement plate 314 correspond to the height of the notch of the support shaft 217, and then the first motor 313 is started to rotate one of the slots 315 on the metal replacement plate 314 to a position below the inner metal circular plate 218, and the other slot 315 is located below the corresponding outer metal circular plate 325. At this time, the metal replacement plate 314 is slowly raised by the electric push rod 311, and the slot 315 on the metal replacement plate 314 passes through the inner metal circular plate 218 and the outer metal circular plate 325, and the metal replacement plate 314 moves the inner metal circular plate 218 to the outer metal circular plate 325. The magnetic crucible holder 4 on the metal circular plate 218 and the outer metal circular plate 325 is lifted up until it reaches a certain height, and then the metal replacement plate 314 is rotated 180 degrees to interchange the positions of the magnetic crucible holders 4 on both sides, and then the metal replacement plate 314 is dropped. When the magnetic crucible holder 4 contacts the inner metal circular plate 218 or the outer metal circular plate 325, since the bottom of the magnetic crucible holder 4 is made of magnetic material, it can be adsorbed on the inner metal circular plate 218 or the outer metal circular plate 325, so that the position of the crucible to be heated and the crucible to be heated can be interchanged. When one crucible is interchanged, the metal replacement plate 314 is rotated to Without affecting the revolution position of the inner metal circular plate 218 and the card slot 315, the outer metal circular plate 325 is driven to rotate by starting the second motor 322, and the magnetic crucible holder 4 on the next outer metal circular plate 325 is moved to a position convenient for the metal replacement plate 314 to grab. At the same time, the magnetic crucible holder 4 on the next inner metal circular plate 218 is also moved to a position convenient for the metal replacement plate 314 to grab. The above replacement steps are repeated, so that all crucible replacements can be completed, solving the problem of high crucible temperature and inconvenience in timely removal. At the same time, a new crucible can be placed while the crucible is taken out, thereby greatly improving work efficiency.
