[0016] A method for using a second type superlattice anti-reflection fixing device comprises the following steps:

[0017] S1. Take the round block out of the alignment board, and place the chip into the circular rubber ring so that the chip contacts the round block to prevent the alignment board from bumping against the second-type superlattice surface of the chip when aligning the chip alone.

[0018] S2. The round blocks taken out are aligned and fixed in batches, which effectively improves the efficiency;

[0019] S3, adjusting the gap between the chip slot plate and the round block, and adjusting the chip slot plate in real time according to the thickness of chips in different batches;

[0020] S4. The circular rubber ring on the chip slot plate restricts the chip so that the chip does not deviate from its position in the circular rubber ring. The anti-reflection film is accurately attached to the second type superlattice surface of the chip.

[0021] S5, the square plate presses against the anti-reflection film, so that the anti-reflection film is pressed against the surface of the second type superlattice of the chip;

[0022] S6. Under the elastic force of the elastic rod, the long strip presses against the rubber roller, so that the horizontal plate remains stable during the upward movement;

[0023] S7, the heat emitted by the resistance heating rod is transferred to the vertical block, the vertical block transfers the heat to the chip slot plate, and the chip slot plate transfers the heat to the chip and the edge of the anti-reflection film;

[0025] S9. The heat-insulating chamber of the baffle blocks the heat emitted by the resistance heating rod, so that the device automatically stops heating the type II superlattice surface of the chip when the chip is enhanced in transmittance.

[0026] The present invention provides a second type of superlattice anti-reflection fixing device, which has the following beneficial effects:

[0027] (1) The present invention uses an alignment plate, an alignment column, a top plate, a round block, a sliding rod, a chip slot plate, a screw rod, a spring 1, a circular rubber ring, a pressure plate, a vertical block, a stop block, a sliding column, a square plate and a spring 2. The circular rubber ring on the chip slot plate restricts the chip, and the chip will not deviate from its position in the circular rubber ring, so that the photosensitive surface of the chip can be accurately affixed with an anti-reflection film, thereby preventing the second-class superlattice surface of the chip from shifting during the movement of the fixing device when in use, resulting in poor film affixing effect on the second-class superlattice surface of the chip. Moreover, under the elastic force of the spring 2, the square plate abuts against the anti-reflection film, allowing the anti-reflection film to be pressed against the photosensitive surface of the chip, thereby preventing the anti-reflection film from being incompletely affixed to the second-class superlattice surface of the chip when the fixing device is in use, resulting in poor pressing effect.

[0028] (2) The present invention arranges a stabilizing device so that the horizontal plate, U-shaped frame, spring rod, long plate, rubber roller, inverted U-shaped rod and concave block cooperate with the spring sheet. Under the elastic force of the spring rod, the long plate will press against the rubber roller to keep the horizontal plate stable during the upward movement. The push block is restricted by the horizontal plate, and the top plate on the push block will not shake violently during the upward movement, thereby preventing the device from shaking violently when the fixing device is in use, resulting in poor anti-reflection effect of the device. When the chip has completed anti-reflection, under the action of the elastic force of the spring sheet, the spring sheet supports the inverted U-shaped rod, the inverted U-shaped rod supports the horizontal plate, the horizontal plate supports the push block, and the push block supports the top plate, thereby preventing the top plate from hitting the alignment plate during the downward movement, thereby preventing the top plate from hitting the alignment plate when the fixing device is in use, resulting in vibration damage to the type II superlattice surface of the chip in the device.

[0029] (3) The present invention arranges the heating device so that the L-shaped plate, the strip shell, the resistance heating rod, the connecting block, the sliding bar and the baffle cooperate with the L-shaped short bar. The heat emitted by the resistance heating rod is transferred to the alignment plate, the alignment plate transfers the heat to the chip slot plate, and the chip slot plate transfers the heat to the chip and the edge of the anti-reflection film, so that when the anti-reflection film is cut, the edge of the anti-reflection film fits with the chip, preventing the edge of the anti-reflection film from not fitting with the second type superlattice surface of the chip when the fixing device is in use, resulting in poor film laminating effect. In addition, the heat-insulating chamber of the baffle blocks the heat emitted by the resistance heating rod, so that the device can automatically stop heating the chip when the chip anti-reflection is completed, preventing the device from heating the chip for a long time when the fixing device is in use, causing heat damage to the second type superlattice surface of the chip.

[0042] An extrusion assembly is provided at the top of the inner part of the plurality of vertical blocks 17, and the extrusion assembly includes a plurality of slide columns 19, and the plurality of slide columns 19 are slidably installed at the top of the inner part of each vertical block 17, and a square plate 20 is fixed to the bottom surface of the plurality of slide columns 19, and a spring 21 is fixed to the top surface of the plurality of square plates 20, and one end of the plurality of springs 21 away from the plurality of square plates 20 is fixed to the top of the inner part of each vertical block 17. Under the elastic force of the spring 21, the square plate 20 presses against the anti-reflection film, so that the anti-reflection film is pressed on the surface of the second type superlattice of the chip, so as to avoid poor pressing effect caused by incomplete fitting between the anti-reflection film and the second type superlattice surface of the chip when the fixing device is in use.

[0043] When in use, the bottom block 1 supports the electric telescopic rod 2, the bottom block 1 supports the U-shaped block 3, the U-shaped block 3 supports the alignment plate 5, the staff can take the round block 10 out of the alignment plate 5, and place the chip into the circular rubber ring 15. The chip contacts the round block 10 to avoid the alignment plate 5 from bumping against the second type superlattice surface of the chip when it is aligned alone. At the same time, the taken out round blocks 10 can be aligned and fixed in batches, which effectively improves the efficiency. The circular rubber ring 15 is limited by the chip slot plate 12, and the chip slot plate 12 fixes the chip. The staff passes the screw 13 through the top of the chip slot plate 12 to rotate The screw 13 drives the chip slot plate 12 to move downward, and the chip slot plate 12 slides downward on the slide bar 11. The spring 14 on the chip slot plate 12 begins to shrink, narrowing the gap between the chip slot plate 12 and the round block 10, so that the chip slot plate 12 can be adjusted in real time according to the thickness of chips in different batches.

The heat emitted by the resistance heating rods 73 is transferred to the alignment plate 5, and the alignment plate 5 transfers the heat to the chip slot plate 12, and the chip slot plate 12 transfers the heat to the chip and the edge of the anti-reflection film, so that the edge of the anti-reflection film fits with the chip when the anti-reflection film is cut, so as to avoid the edge of the anti-reflection film not fitting with the second type superlattice surface of the chip when the fixing device is in use, resulting in poor film pasting effect.

[0048] The heating device 7 further includes four connecting blocks 74, four sliding bars 75, two baffles 76 and four L-shaped short bars 77. The four connecting blocks 74 are fixed to the bottom surfaces of the two bar shells 72, the four sliding bars 75 are fixed directly opposite the four connecting blocks 74, the two baffles 76 are slidably mounted on the outer walls of the four sliding bars 75, the two baffles 76 are located on the front of the two bar shells 72, the four L-shaped short bars 77 are respectively fixed to both sides of the bottom surfaces of the two baffles 76, and the four L-shaped short bars 77 are away from the two baffles 76. One end is fixed to the front and back of the alignment plate 5, and sliding grooves are provided on both sides of the front of the two baffles 76. The sliding grooves of the two baffles 76 are slidably connected to the outer walls of the four sliding bars 75. The interior of the two baffles 76 is provided with a heat-insulating chamber, and the heat-insulating chamber of the baffle 76 blocks the heat emitted by the resistance heating rod 73, so that the device can automatically stop heating the chip when the chip transmittance is increased, so as to avoid the device heating the second type superlattice surface of the chip for a long time when the fixing device is in use, causing heat damage to the chip.

[0049] A method for using a second type superlattice anti-reflection fixing device comprises the following steps:

[0050] S1, take out the round block 10 from the alignment plate 5, and place the chip into the circular rubber ring 15, so that the chip contacts the round block 10, so as to avoid the alignment plate 5 bumping against the second type superlattice surface of the chip when aligning alone;

[0051] S2, the round blocks 10 taken out are aligned and fixed in batches, which effectively improves the efficiency;

[0052] S3, adjusting the gap between the chip slot plate 12 and the round block 10, and adjusting the chip slot plate 12 in real time according to the thickness of chips in different batches;

[0053] S4, the circular rubber ring 15 on the chip slot plate 12 restricts the chip, the chip does not deviate from the position in the circular rubber ring 15, and the anti-reflection film is accurately attached to the second type superlattice surface of the chip;

[0054] S5, the square plate 20 presses against the anti-reflection film, so that the anti-reflection film is pressed on the surface of the second type superlattice of the chip;

[0055] S6. Under the elastic force of the elastic rod 63, the long strip 64 presses against the rubber roller 65, so that the horizontal plate 61 remains stable during the upward movement;

[0056] S7, the heat emitted by the resistance heating rod 73 is transferred to the vertical block 17, the vertical block 17 transfers the heat to the chip slot plate 12, and the chip slot plate 12 transfers the heat to the chip and the edge of the anti-reflection film;

[0057] S8, when the chip has completed the anti-reflection, under the action of the elastic force of the spring sheet 68, the spring sheet 68 supports the inverted U-shaped rod 66, so that the top plate 9 does not hit the alignment plate 5;

[0058] S9. The heat-insulating chamber of the baffle 76 blocks the heat emitted by the resistance heating rod 73, so that the device automatically stops heating the type II superlattice surface of the chip when the chip is enhanced in transmittance.

[0059] When the stop block 18 moves upward, the stop block 18 drives the cross plate 61 to move upward, and the cross plate 61 drives the rubber roller 65 to move upward. At the same time, the bottom block 1 supports the U-shaped frame 62, the U-shaped frame 62 supports the elastic rod 63, and the elastic rod 63 supports the long plate 64. Under the action of friction, the rubber roller 65 rolls on the long plate 64. Under the elastic force of the elastic rod 63, the long plate 64 will press against the rubber roller 65 to keep the cross plate 61 stable during the upward movement. The stop block 18 is restricted by the cross plate 61, so that the top plate 9 on the stop block 18 will not shake violently during the upward movement, thereby preventing the device from shaking during the upward movement, thereby avoiding the problem of poor transmittance enhancement effect of the device caused by violent shaking of the device when the fixing device is in use.

[0060] When the support block 18 drives the horizontal plate 61 to move upward, the horizontal plate 61 drives the inverted U-shaped rod 66 to move upward. When the chip completes the transmittance enhancement, the horizontal plate 61 drives the inverted U-shaped rod 66 to move downward. At the same time, the bottom block 1 supports the concave block 67, the concave block 67 supports the spring piece 68, and the two ends of the inverted U-shaped rod 66 contact the spring piece 68, which deforms. Under the action of the elastic force of the spring piece 68, the spring piece 68 supports the inverted U-shaped rod 66, and the inverted U-shaped rod 66 supports the horizontal plate 61. The horizontal plate 61 supports the support block 18, and the support block 18 supports the top plate 9, so that the top plate 9 will not hit the alignment plate 5 during the downward movement, thereby preventing the top plate 9 from hitting the alignment plate 5, thereby avoiding the problem of vibration damage to the second type superlattice surface of the chip in the device caused by the top plate 9 hitting the alignment plate 5 when the fixing device is in use.

[0061] While the horizontal plate 61 drives the inverted U-shaped rod 66 to move upward, the inverted U-shaped rod 66 drives the L-shaped plate 71 to move upward, the L-shaped plate 71 drives the strip shell 72 to move upward, the strip shell 72 drives the resistance heating rod 73 to move upward, the resistance heating rod 73 is started, the resistance heating rod 73 begins to heat up, the heat emitted by the resistance heating rod 73 is transferred to the alignment plate 5, the alignment plate 5 transfers the heat to the chip slot plate 12, the chip slot plate 12 transfers the heat to the chip and the edge of the anti-reflection film, so that the edge of the anti-reflection film fits the chip when the anti-reflection film is cut, to prevent the edge of the anti-reflection film from not fitting with the second type superlattice surface of the chip when the equipment is in use, thereby avoiding the problem of poor film bonding effect caused by the edge of the anti-reflection film not fitting with the second type superlattice surface of the chip when the fixing device is in use.

[0062] When the L-shaped plate 71 drives the strip shell 72 to move upward, the strip shell 72 drives the connecting block 74 to move upward, and the connecting block 74 drives the sliding bar 75 to move upward, and the sliding bar 75 slides upward in the sliding groove of the baffle 76. At the same time, the alignment plate 5 supports the L-shaped short rod 77, and the L-shaped short rod 77 supports the baffle 76. When the chip transmittance enhancement is completed, the strip shell 72 drives the connecting block 74 to move downward, and the connecting block 74 drives the sliding bar 75 to move downward, and the sliding bar 75 slides downward in the sliding groove of the baffle 76. The baffle 76 blocks the strip shell 72, so that the heat insulation chamber of the baffle 76 blocks the heat emitted by the resistance heating rod 73, so that the equipment can automatically stop heating the second type superlattice surface of the chip when the chip transmittance enhancement is completed, thereby avoiding the problem of heat damage to the chip caused by the equipment heating the second type superlattice surface of the chip for a long time when the fixing device is in use.
