[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 any creative efforts shall fall within the scope of protection of the present invention.

[0025] In the existing electronic chip production process, the dry etching process using top-down micromachining technology is prone to cause secondary damage to the electronic chip.

[0026] When the present invention is in use, after the substrate is produced, it falls onto the conveyor belt 21. The substrate moves along the conveyor belt 21 to the bottom of the three clamps 665 and is clamped by the three clamps 665. The fifth electric telescopic rod 65 moves with the clamps 665 holding the substrate to the top of the ultrasonic cleaner 41 and is cleaned in the inner cavities of the three cleaning tanks 411 respectively. The inner cavities of the three cleaning tanks 411 are filled with acetone, isopropyl alcohol, and deionized water in sequence. The order of the cleaning agents ensures a gradient transition from strong polarity to weak polarity solvents to avoid solvent residue. After the substrate is cleaned in sequence, it is moved to the inner cavity of the drying box 43 for drying. Finally, the dried substrate is placed on the top of the conveyor belt 21. The substrate moves along the conveyor belt 21 and is collected by the staff.

[0027] Further, such as Figure 2 and Figure 3 As shown, two conveying rollers 2 are rotatably installed on the inner surface of the first groove 11, and the conveyor belt 21 is wound and installed on the outer surface of the two conveying rollers 2. A first motor 22 is fixedly connected to one side of one of the conveying rollers 2, and the first motor 22 is fixedly installed on one side of the support plate 1; The output shaft of the first motor 22 is fixedly connected to an incomplete gear 23, a limiting tube 25 is fixedly installed on one side of the support plate 1, a gear 26 is rotatably installed on one side of the support plate 1, a rack 24 is slidably installed on the inner surface of the limiting tube 25, the incomplete gear 23 and the gear 26 are both engaged with the rack 24, and a first spring 27 is fixedly connected to one side of the rack 24, and the first spring 27 is fixedly installed on one side of the support plate 1; Two second grooves 12 are provided on the top of the support plate 1, and a bidirectional threaded rod 261 is rotatably installed on the inner surface of the second groove 12, and an L-shaped slider 262 is slidably installed on the inner surface of the second groove 12. A clamping block 263 is fixedly connected to one side of the L-shaped slider 262, and the bidirectional threaded rod 261 is fixedly connected to one side of the gear 26.

[0028] When the present invention is in use, the output shaft of the first motor 22 first drives the conveyor roller 2 to rotate, and when the conveyor roller 2 rotates, the conveyor belt 21 is rotated to realize the conveyance of the substrate. The output shaft of the first motor 22 simultaneously drives the incomplete gear 23 to rotate. The incomplete gear 23 can drive the rack 24 to slide along the limiting tube 25. When the rack 24 slides, it will drive the gear 26 to rotate, and in the gap where the incomplete gear 23 is not engaged with the rack 24, the first spring 27 will push the rack 24 to slide. When the gear 26 rotates, it will synchronously drive the bidirectional threaded rod 261 to rotate. The bidirectional threaded rod 261 can drive the L-shaped slider 262 to slide along the inner cavity of the second groove 12. The two L-shaped sliders 262 respectively drive the two clamping blocks 263 to slide back and forth toward each other, which can squeeze the substrate on the conveyor belt 21 to the middle.

[0029] Further, such as Figure 4 As shown, a first electric telescopic rod 31 is fixedly installed on the top of the top plate 3, and the output end of the first electric telescopic rod 31 is fixedly connected to a production box 32. A first sealing plate 322 is fixedly installed on the bottom of the top plate 3. A third groove 321 is provided on the top of the production box 32. The first sealing plate 322 is slidably installed on the inner surface of the third groove 321. A vacuum pump 323 and a nitrogen pipe 324 are fixedly connected to the outer surface of the production box 32. A second electric telescopic rod 35 is fixedly installed on the outer surface of the production box 32, and the output end of the second electric telescopic rod 35 is fixedly connected to a second sealing plate 36.

[0030] When the present invention is in use, first, when producing a substrate, the production box 32 is first lifted by the first electric telescopic rod 31 so that the first sealing plate 322 can seal the third groove 321 and the first sealing plate 322, and then the inner cavity of the production box 32 is placed in a vacuum state by the vacuum pump 323, and then the raw materials are transported to the inner cavity of the production box 32 through the nitrogen pipe 324 to produce the substrate. After the production is completed, the first electric telescopic rod 31 drives the production box 32 to descend again. At this time, the output end of the second electric telescopic rod 35 slides with the second sealing plate 36, and the second sealing plate 36 moves away from the bottom of the production box 32, which can make the substrate on the second sealing plate 36 fall onto the conveyor belt 21.

[0031] Further, such as Figure 5 As shown, a detector 5 and a connecting block 51 are fixedly connected to one side of the ultrasonic cleaner 41, four third electric telescopic rods 52 are fixedly installed at the bottom of the connecting block 51, the output end of the third electric telescopic rod 52 is fixedly connected to a second spring 53, and one end of two adjacent second springs 53 is commonly fixedly connected to a baffle 54, and the top of the baffle 54 is fixedly connected to a vibrator 55.

[0032] When the present invention is in use, the substrate moves to the bottom of the detector 5 along with the conveyor belt 21, and the detector 5 detects the substrate. According to different detection results, the detector 5 can drive different third electric telescopic rods 52 to extend. Different extensions of the third electric telescopic rods 52 can cause different baffles 54 to contact the top surface of the conveyor belt 21. The baffles 54 block the substrate and the movement path of the substrate can be adjusted. When in use, the vibrator 55 can make the baffle 54 vibrate continuously, and the second spring 53 can further increase the amplitude of the baffle 54. The vibration of the baffle 54 can prevent the substrate from stopping on one side of the baffle 54.

[0033] Further, such as Figure 6 and Figure 7 As shown, a fifth groove 302 is provided on the top of the top plate 3, a threaded rod 6 is rotatably mounted on one side of the top plate 3, one end of the threaded rod 6 is fixedly connected to a second motor 61, and the second motor 61 is fixedly mounted on one side of the top plate 3, the outer surface of the threaded rod 6 is threadedly connected to a sliding block 62, one side of the sliding block 62 is fixedly connected to a fourth electric telescopic rod 63, the outer surface of the fourth electric telescopic rod 63 is fixedly connected to a limiting slider 64, the limiting slider 64 is slidably mounted on the inner surface of the fifth groove 302, and the output end of the fourth electric telescopic rod 63 is fixedly connected to the outer surface of the fifth electric telescopic rod 65; The output end of the fifth electric telescopic rod 65 is fixedly connected to a rotating block 66, the inner surface of which is rotatably connected to a connecting column 662. One side of the rotating block 66 is fixedly connected to a third motor 661, and the output shaft of the third motor 661 is fixedly connected to one side of the connecting column 662. A sliding plate 663 is slidably mounted on the outer surface of the connecting column 662, and three connecting rods 666 are rotatably mounted on the outer surface of the sliding plate 663. The bottom of the connecting column 662 is fixedly connected to a fixed plate 664, and the three clamping claws 665 are rotatably mounted on the outer surface of the fixed plate 664. One end of the connecting rod 666 is rotatably mounted on the top of the clamping claw 665. Three sixth electric telescopic rods 667 are fixedly mounted on the top of the fixed plate 664, and the output end of the sixth electric telescopic rod 667 is fixedly connected to the bottom of the sliding plate 663.

[0034] When the present invention is in use, when it is necessary to clamp a substrate, the threaded rod 6 is first rotated by the output shaft of the second motor 61. When the threaded rod 6 rotates, the limiting slider 64 slides in the inner cavity of the fifth groove 302 to drive the fourth electric telescopic rod 63 to slide. After the clamping claw 665 is moved to the top of the substrate, the output end of the fifth electric telescopic rod 65 drives the connecting column 662 to move downward. After the three clamping claws 665 are at the periphery of the substrate, the output ends of the three sixth electric telescopic rods 667 are synchronously extended to drive the sliding plate 663 to move upward. The sliding plate 663 drives the three connecting rods 666 to rotate. The three connecting rods 666 respectively drive the three clamping claws 665 to clamp the substrate. Then, the fifth electric telescopic rod 65, the fourth electric telescopic rod 63 and the threaded rod 6 cooperate to move and clean the substrate. After cleaning is completed, the output shaft of the third motor 661 drives the connecting column 662 to rotate, and the connecting column 662 can move the clamped substrate to the inner cavity of the drying box 43 in one step. At this time, hot air is transported to the inner cavity of the drying box 43 through the hot air pipe 44, which can quickly dry the substrate.

[0035] A method for preparing a GaN-based optoelectronic chip based on a micro-nano array structure, the method using the device for preparing a GaN-based optoelectronic chip based on a micro-nano array structure, and the method comprising the following steps: S1: First, a substrate for manufacturing electronic chips is produced in the inner cavity of the production box 32; S2: The substrate is then placed on the conveyor belt 21 and moves along the conveyor belt 21 to the bottom of the clamp 665; S3: Then the three clamps 665 cooperate to pick up the substrate and place it in the ultrasonic cleaner 41 for cleaning. After cleaning, the substrate is placed in the inner cavity of the drying box 43 for drying. S4: Finally, the dried substrate is placed on the top of the conveyor belt 21. As the conveyor belt 21 moves to the bottom of the detector 5, the detector 5 detects the substrate; S5: The two baffles 54 fall down respectively according to different detection results, diverting the substrate so that the substrate moves in different directions.

[0036] Working principle: First, the inner cavity of the production box 32 is in a vacuum state through the vacuum pump 323, and then the substrate raw materials are input into the inner cavity of the production box 32 through the nitrogen pipe 324 to produce the substrate. After the substrate production is completed, the second electric telescopic rod 35 moves with the second sealing plate 36 to drop the substrate to the top of the conveyor belt 21. The output shaft of the first motor 22 drives the conveyor roller 2 to rotate, so that the conveyor roller 2 drives the conveyor belt 21 to rotate and thus move the substrate. When the output shaft of the first motor 22 rotates, it also drives the incomplete gear 23 to rotate. The incomplete gear 2 The rack 24 is further driven to slide along the limiting tube 25, while the rack 24 also rotates the gear 26. When the incomplete gear 23 is not engaged with the rack 24, the first spring 27 can return the rack 24 to its initial position. The rotation of the gear 26 can rotate the bidirectional threaded rod 261, which further drives the two clamping blocks 263 toward each other. With the action of the first spring 27, the two clamping blocks 263 move back and forth in a reciprocating cycle. This can adjust the substrate to the middle position of the conveyor belt 21 when the substrate passes between the two clamping blocks 263.

[0037] When the substrate moves to the bottom of the clamp 665, the threaded rod 6 is rotated by the output shaft of the second motor 61, and the horizontal position of the clamp 665 can be adjusted by extending and shortening the output end of the fourth electric telescopic rod 63. The vertical position of the clamp 665 can be adjusted by extending and shortening the fifth electric telescopic rod 65, so that the three clamps 665 are around the substrate. Then, the output end of the sixth electric telescopic rod 667 is retracted, and the sliding plate 663 is slid upward along the connecting column 662, so that the three connecting rods 666 are rotated to make the three clamps 665 approach each other and clamp the substrate. Then, the substrate is moved to the inner cavity of the cleaning tank 411, the substrate is cleaned, and finally the substrate is dried in the inner cavity of the drying box 43. Then, the substrate falls to the top of the conveyor belt 21, the substrate is detected by the detector 5, and the baffle 54 is used to classify and collect the substrate according to different detection results.
