[0002] As a key equipment in the modern electronic manufacturing industry, the exposure machine is responsible for the important task of accurately transferring fine patterns to the substrate.

[0042] In the initial state, the flip mechanism 6 is located on the side of the housing 1 close to the feed inlet 101, and the positioning frame 710 is located above the conveyor belt 8 at the feed inlet 101, the sliding rod 613 is at the bottom of the Z-shaped groove 615, and the soft rubber suction cup 712 is facing downward. The staff places the circuit board with the exposure film on the conveyor belt 8 of the feed inlet 101, and starts the conveyor belt 8 so that the conveyor belt 8 drives the circuit board into the housing 1. When the circuit board is located below the positioning frame 710, the conveyor belt 8 is stopped, and then the second motor 601 is started. The output shaft of the second motor 601 rotates to drive the second screw rod 602 to rotate synchronously. The second screw rod 602 rotates to make the second threaded sleeve 604 rotate along the axis of the second screw rod 602. The second threaded sleeve 604 moves in the central direction close to the conveyor belt 8, the second threaded sleeve 604 moves to drive the mounting plate 606 to slide synchronously, and when the mounting plate 606 slides, it drives the sliding shell 607 and the positioning shaft 608 to move, and the sliding shell 607 moves through the L-shaped support frame 612 to drive the sliding rod 613 to slide horizontally at the bottom of the Z-shaped groove 615, and the positioning shaft 608 moves to drive the air column 701 and the T-shaped shaft 616 to move synchronously, so that the flipping mechanism 6 pushes the suction cup mechanism 7 to move forward; on the one hand, the T-shaped shaft 616 slides into the groove 801 on the side of the conveyor belt 8 to prevent it from colliding with the conveyor belt 8; on the other hand, when the air column 701 moves, it drives the first air cylinder 702 to move through the first compression spring, and the first air cylinder 702 drives the L The L-shaped rotating frame 703 moves and contacts the conveyor belt 8. At this time, the first air cylinder 702 and the L-shaped rotating frame 703 are restricted by the conveyor belt 8 and remain stationary, while the positioning frame 710 is located directly above the circuit board. The second motor 601 continues to work, so that the air column 701 continues to push the first compression spring to compress the first compression spring. At the same time, the volume of the gas in the air column 701 and the first air cylinder 702 becomes smaller, and the gas inside them enters the first hose through the first vent hole, and enters the telescopic cylinder 704 through the second vent hole. The gas pressure in the telescopic cylinder 704 increases, so that the gas in the telescopic cylinder 704 pushes the telescopic rod 705 to slide downward, and the telescopic rod 705 slides downward to drive the angular gear plate 707 to move downward, and the second air cylinder 706 moves downward synchronously with the angle toothed disc 707 under the action of its own gravity, and the second air cylinder 706 moves through the positioning frame 710 to drive the suction cup shell 711 to move downward synchronously. When the suction cup shell 711 moves downward, the soft glue suction cup 712 approaches and contacts the circuit board. When the soft glue suction cup 712 moves downward and contacts the circuit board, the telescopic rod 705 continues to slide downward to make the inclined surface of one side of the triangular tooth 7071 of the angle toothed disc 707 contact the narrow ratchet 7081, and the triangular groove 7072 contacts the wide ratchet 7082. It is worth noting that in the initial state, the bottom end inclined surface of the ratchet block 709 is located at the ratchet angle groove 7083, so that the ratchet disc 708 is limited by the ratchet block 709 and cannot rotate.The angular toothed disk 707 continues to push the narrow ratchet teeth 7081 and the wide ratchet teeth 7082 downward to move downward, thereby causing the ratchet block 709 to disengage from the ratchet angular groove 7083, and the ratchet disk 708 is no longer limited by the ratchet block 709. The ratchet disk 708 can rotate, and at the same time, the ratchet disk 708 moves downward to compress the second compression spring, and the angular toothed disk 707 continues to slide downward, and the triangular teeth 7071 and the triangular groove 7072 squeeze the narrow ratchet teeth 7081 and the wide ratchet teeth 7082 respectively. The narrow ratchet teeth 7081 and the wide ratchet teeth 7082 rotate after being squeezed, and the top inclined surface of the narrow ratchet teeth 7081 rotates along the inclined surface of one side of the triangular teeth 7071, and the top inclined surface of the wide ratchet teeth 7082 rotates along the triangular groove 7072 until the top tooth tip of the wide ratchet teeth 7082 slides into the top of the triangular groove 7072 and is limited, thereby The ratchet disc 708 is limited, and the ratchet disc 708 cannot rotate at this time. Then the angle tooth disc 707 continues to slide downward, thereby pushing the ratchet disc 708 to slide downward, so that the volume of the gas between the ratchet disc 708 and the second air cylinder 706 is reduced, and the gas in the second air cylinder 706 enters the second hose through the fourth vent hole, and enters the suction cup shell 711 through the third vent hole. The air pressure in the suction cup shell 711 increases, causing the soft glue suction cup 712 to expand. The soft glue suction cup 712 can better fit the circuit board and push out the air under the soft glue suction cup 712, so that the suction cup mechanism 7 can absorb the circuit board; at the same time, the positioning frame 710 squeezes the third compression spring to make the third compression spring absorb pressure, thereby preventing the soft glue suction cup 712 from rigidly squeezing the circuit board and causing the circuit board to break. ;

[0043] Afterwards, the second motor 601 rotates in the opposite direction, and the output shaft of the second motor 601 rotates to drive the second screw rod 602 to rotate synchronously. The second screw rod 602 rotates to make the second threaded sleeve 604 move along the axial direction of the second screw rod 602 away from the conveyor belt 8. The movement of the second threaded sleeve 604 drives the mounting plate 606 to slide synchronously. When the mounting plate 606 slides, it drives the sliding shell 607 and the positioning shaft 608 to move. The sliding shell 607 moves through the L-shaped support frame 612 to drive the sliding rod 613 to slide horizontally at the bottom of the Z-shaped groove 615. The movement of the positioning shaft 608 drives the gas column 701 and the T-shaped shaft 616 to move synchronously, so that the flipping mechanism 6 pushes the suction cup mechanism 7 to move backward; on the one hand, the T-shaped shaft 616 slides out of the groove 801 on the side of the conveyor belt 8;On the other hand, when the gas column 701 moves, the first compression spring is gradually loosened, so that the volume of the gas between the gas column 701 and the first gas cylinder 702 increases and the air pressure decreases. The first gas cylinder 702 draws gas to the first hose through the first vent hole, and the first hose draws gas to the telescopic cylinder 704 through the second vent hole. The air pressure of the gas between the telescopic cylinder 704 and the telescopic rod 705 decreases, so that the gas pulls the telescopic rod 705 to slide upward. When the telescopic rod 705 slides upward, it drives the angular toothed plate 707 to move synchronously. At this time, the second compression spring is released to drive the ratchet plate 708 to slide upward, and the ratchet plate 708 drives the narrow ratchet 7081 and the wide ratchet 7082 to move upward synchronously until the inclined surface of the narrow ratchet 7081 contacts the bottom inclined surface of the ratchet block 709, so that the ratchet plate 708 08 is limited by the ratchet block 709 and cannot move upward. At this time, the ratchet plate 708 can rotate, and then the angle tooth plate 707 continues to slide upward, and the second compression spring continues to push the ratchet plate 708 to slide upward, so that the wide ratchet tooth 7082 disengages from the triangular groove 7072. Since the ratchet plate 708 is limited by the ratchet block 709 and cannot move upward, the second compression spring pushes the ratchet plate 708 to move, so that the narrow ratchet tooth 7081 squeezes the ratchet block 709 and rotates along the inclined surface of the ratchet block 709. Finally, the second sliding groove of the ratchet plate 708 rotates to the ratchet block 709. At this time, the ratchet plate 708 can slide upward, and the second compression spring continues to release and push the ratchet plate 708 to slide upward, and the ratchet block 709 will enter the second sliding groove to limit the ratchet plate 708 At this time, the ratchet plate 708 cannot rotate. As the second compression spring continues to be released, the ratchet plate 708 slides upward, causing the narrow ratchet tooth 7081 to contact the triangular groove 7072, and the wide ratchet tooth 7082 to contact the inclined surface of one side of the triangular tooth 7071. As the ratchet plate 708 slides upward, the volume of gas in the second gas cylinder 706 increases and the air pressure decreases, causing the second gas cylinder 706 to draw air to the second hose through the fourth vent hole, and the second hose then draws air to the suction cup shell 711 through the third vent hole, reducing the air pressure in the suction cup shell 711. The gas in the suction cup shell 711 pulls the soft rubber suction cup 712 inward, increasing the space between the soft rubber suction cup 712 and the circuit board. Since the quality of the gas between the soft rubber suction cup 712 and the circuit board has not changed, The air pressure is reduced, forming a suction cavity, so that the suction cup mechanism 7 can adsorb the circuit board; when the suction cup mechanism 7 completes the adsorption of the circuit board, the angle toothed disc 707 is pulled to the top of the second air cylinder 706 by the telescopic rod 705, and as the air column 701 continues to slide and releases the first compression spring, the telescopic rod 705 drives the second air cylinder 706 to slide upward through the angle toothed disc 707, and the second air cylinder 706 drives the positioning frame 710 to slide upward, and the positioning frame 710 drives the suction cup shell 711 to move upward. When the suction cup shell 711 moves upward, the circuit board is lifted through the soft rubber suction cup 712, so that the circuit board is separated from the conveyor belt 8. When the first compression spring is completely released, the air column 701 continues to slide, and drives the first air cylinder 702 to move synchronously through the first compression spring, and then stops the second motor 601. ;

[0044] The first motor 301 is started, and the output shaft of the first motor 301 rotates to drive the first screw rod 302 to rotate. When the first screw rod 302 rotates, the sliding table 306 is driven to slide axially close to the exposure platform 9 through the first threaded sleeve 304. When the sliding table 306 slides, the flip mechanism 6 is driven to move through the first vertical plate 4 and the second vertical plate 5. The flip mechanism 6 drives the suction cup mechanism 7 to move synchronously, so as to realize the left and right horizontal movement of the suction cup mechanism 7; the horizontal movement of the suction cup mechanism 7 drives the circuit board to move synchronously, and the first motor 301 controls the suction cup mechanism 7 to move toward the exposure platform 9. When the circuit board is located at When the exposure platform 9 is above the exposure platform 9, the first motor 301 is stopped and the second motor 601 is started, so that the flip mechanism 6 performs the forward movement in the above example again, so that the T-shaped shaft 616 and the gas column 701 slide forward. On the one hand, the positioning shaft 608 pushes the T-shaped shaft 616 forward to contact and squeeze the sealing plug 902, and the sealing plug 902 squeezes the hydraulic oil and compresses the fourth compression spring, so that the hydraulic oil enters the airtight channel 903 through the hydraulic channel 901 and pushes the sealing slider 904 to slide, and the sealing slider 904 discharges the air therein through the fifth vent hole at the top of the airtight channel 903;On the other hand, the air column 701 slides to make the suction cup mechanism 7 perform the downward movement in the above example again, so that the soft rubber suction cup 712 drives the circuit board to move downward, and the circuit board contacts with the exposure platform 9 and fits the fifth vent hole opened on the exposure platform 9. At this time, the telescopic rod 705 continues to move downward, so that the angle toothed disc 707 pushes the narrow ratchet 7081 and the wide ratchet 7082 to move downward, and then pushes the ratchet disc 708 to slide downward along the ratchet block 709, and the second compression spring contracts under the force, so that the ratchet disc 708 slides downward. The second sliding groove opened by the ratchet block 709 will be disengaged from the ratchet block 709. At this time, the ratchet block 709 no longer restricts the ratchet plate 708, and the ratchet plate 708 can rotate. Subsequently, the second compression spring is released and gives an upward force to the ratchet plate 708. Since the angle toothed plate 707 is still moving downward, the second compression spring cannot push the ratchet plate 708 to move upward, and the upward force of the ratchet plate 708 will be transmitted to the narrow ratchet teeth 7081 and the wide ratchet teeth 7082, causing the narrow ratchet teeth 7081 and the wide ratchet teeth 7082 to squeeze the three The narrow ratchet 7081 and the wide ratchet 7082 rotate under the reaction force, the wide ratchet 7082 rotates along the inclined surface of the triangular tooth 7071, and the narrow ratchet 7081 rotates along the triangular groove 7072. Finally, the narrow ratchet 7081 rotates to the top of the triangular groove 7072 and is limited. At this time, the ratchet plate 708 cannot rotate. Then the angular tooth plate 707 continues to push the ratchet plate 708 to the bottom end of the second air cylinder 706, so that the second compression spring is compressed. At the same time , the volume of gas between the second gas cylinder 706 is reduced, the gas in the second gas cylinder 706 enters the second hose through the fourth vent hole, and enters the suction cup shell 711 through the third vent hole, the air pressure in the suction cup shell 711 increases, causing the soft glue suction cup 712 to expand outward, the volume of the cavity between the soft glue suction cup 712 and the circuit board is reduced, the air pressure increases, causing the soft glue suction cup 712 to release the circuit board, and the circuit board is placed, and the positioning frame 710 absorbs the pressure by squeezing the third compression spring, thereby protecting the circuit board. ;

[0045] The second motor 601 is reversed again, so that the flip mechanism 6 moves backward again, and the T-axis 616 and the air column 701 slide backward. On the one hand, the T-axis 616 slides backward to release the fourth compression spring to push the sealing plug 902, so that the volume of the hydraulic channel 901 increases, and the hydraulic channel 901 absorbs hydraulic oil into the airtight channel 903, so that the sealing slider 904 slides with the hydraulic oil, and the sealing slider 904 draws air through the fifth air vent at the top of the airtight channel 903, so as to realize the action of air suction on the exposure platform 9, and there is a circuit board above the fifth air vent, so that suction is generated in the airtight channel 903 to adsorb the circuit board; on the other hand, the air column 701 moves backward to cause the first air cylinder 702 to draw air into the first hose through the first air vent. The first hose draws gas to the telescopic cylinder 704 through the second vent hole, and the gas pressure between the telescopic cylinder 704 and the telescopic rod 705 is reduced, so that the gas pulls the telescopic rod 705 to slide upward. When the telescopic rod 705 slides upward, it drives the angle toothed plate 707 to move synchronously. During the upward movement of the angle toothed plate 707, the second compression spring is released to drive the ratchet plate 708 to slide upward until the wide ratchet teeth 7082 contact the ratchet block 709, and the ratchet block 709 limits the ratchet plate 708 so that it cannot move upward. At this time, the angle toothed plate 707 continues to slide upward, so that the narrow ratchet teeth 7081 are disengaged from the limit of the triangular groove 7072 of the angle toothed plate 707. At this time, the ratchet plate 708 can rotate, and with the release of the second compression spring, the wide ratchet teeth 7082 The ratchet block 709 rotates along the inclined surface until the bottom inclined surface of the ratchet block 709 is stuck in the ratchet angle groove 7083, so that the ratchet plate 708 and the ratchet block 709 remain relatively still, and the angle tooth plate 707 continues to slide to the top of the second air cylinder 706. At this time, the gas volume in the second air cylinder 706 increases and the air pressure decreases, so that the second air cylinder 706 draws air to the second hose through the fourth vent hole, and the second hose then draws air to the suction cup shell 711 through the third vent hole, so that the air pressure in the suction cup shell 711 is reduced, and the gas in the suction cup shell 711 pulls the soft rubber suction cup 712 to shrink, so that the gas volume between the soft rubber suction cup 712 and the circuit board increases, and the air pressure decreases, forming a suction cavity. 06 slides upward over a small distance, so that the air pressure in the suction cup housing 711 only decreases slightly, and the airtight channel 903 of the exposure platform 9 adsorbs the circuit board, resulting in that the suction force of the cavity between the soft glue suction cup 712 and the circuit board is insufficient to lift the circuit board against gravity, and the suction cup mechanism 7 cannot grab the circuit board. As the positioning shaft 608 and the air column 701 continue to move, the suction cup mechanism 7 again moves the soft glue suction cup 712 upward to complete the resetting of the suction cup mechanism 7; then the second motor 601 is stopped and the extreme purple lamp 2 is started. The extreme purple lamp 2 irradiates parallel ultraviolet light through the exposure template 10 onto the circuit board, causing the exposure film on the circuit board to undergo a chemical reaction and adhere to the circuit board, thereby completing the exposure of the circuit board.

[0046] After the circuit board is exposed, the second motor 601 is started again, so that the flipping mechanism 6 performs the forward movement operation again, and the T-shaped shaft 616 and the air column 701 slide forward. On the one hand, the positioning shaft 608 pushes the T-shaped shaft 616 forward again to contact and squeeze the sealing plug 902. The sealing plug 902 squeezes the hydraulic oil and compresses the fourth compression spring, so that the hydraulic oil enters the airtight channel 903 through the hydraulic channel 901 and pushes the sealing slider 904 to slide. The sliding of the sealing slider 904 reduces the gas volume of the airtight channel 903 and increases the pressure. The fifth vent hole at the top of the airtight channel 903 cannot generate suction on the circuit board; on the other hand, the suction cup mechanism 7 performs the adsorption action on the circuit board again, so that the circuit board is adsorbed on the soft rubber suction cup 712.

[0047] The second motor 601 is started again to rotate in the opposite direction, so that the flipping mechanism 6 performs the backward movement operation again, and the T-axis 616 and the air column 701 slide backward. On the one hand, the air column 701 slides backward to make the suction cup mechanism 7 perform the upward movement of the soft glue suction cup 712 again; on the other hand, the T-axis 616 slides backward to release the fourth compression spring to push the sealing plug 902, so that the volume of the hydraulic channel 901 increases, and the hydraulic channel 901 absorbs hydraulic oil into the airtight channel 903, and the sealing slider 904 slides with the hydraulic oil. The sealing slider 904 draws air through the fifth air hole at the top of the airtight channel 903, and there is a circuit board above the fifth air hole, so that suction is generated in the airtight channel 903 to adsorb the circuit board, but in the process of gradually increasing the suction force of adsorbing the circuit board, the circuit board has been adsorbed by the soft glue suction cup 712 and lifted by the suction cup mechanism 7, so that the circuit board is separated from the fifth air hole at the top of the airtight channel 903, and the outside air enters the airtight channel 903.

[0048] The second motor 601 continues to rotate in the reverse direction, so that the flip mechanism 6 continues to perform the operation of moving backward. At this time, the sliding shell 607 moves away from the exposure platform 9. When the sliding shell 607 moves, the sliding rod 613 is driven by the L-shaped support frame 612 to continue to slide along the Z-shaped groove 615. When the sliding rod 613 slides on the inclined surface of the Z-shaped groove 615, the sliding rod 613 pushes the sliding shell 607 to move upward through the L-shaped support frame 612, so that when the sliding shell 607 moves, it drives the rack 609 to slide synchronously, and when the rack 609 slides, it drives the gear 610 to mesh and rotate until the bottom of the first sliding groove of the sliding shell 607 is aligned with the fixed When the positioning shaft 608 is in contact, the gear 610 rotates and squeezes the end face of the elastic ratchet piece 611 through the columnar ratchet groove, so that the elastic ratchet piece 611 rotates with the gear 610 and drives the positioning shaft 608 to rotate synchronously. When the positioning shaft 608 rotates, it drives the suction cup mechanism 7 to rotate synchronously, so that the circuit board is rotated 180° by the suction cup mechanism 7; the second motor 601 is started again to make the flip mechanism 6 continue to perform the forward movement operation. In this process, the sliding shell 607 pushes the sliding rod 613 to move forward through the L-shaped support frame 612 until the sliding rod 613 slides into the inclined surface of the Z-shaped groove 615, and the inclined surface of the Z-shaped groove 615 squeezes The sliding rod 613 pushes the sliding shell 607 downward through the L-shaped support frame 612. When the sliding shell 607 moves, it drives the rack 609 to slide synchronously, so that when the rack 609 slides, it drives the gear 610 to mesh and rotate until the top of the first sliding groove of the sliding shell 607 contacts the positioning shaft 608. When the gear 610 rotates, the gear 610 squeezes the side of the elastic ratchet piece 611 through the columnar ratchet groove, so that the columnar ratchet groove of the gear 610 rotates around the elastic ratchet piece 611, so that the suction cup mechanism 7 does not rotate, and the sliding shell 607 continues to approach the exposure platform 9. The sliding shell 607 pushes The dynamic air column 701 moves synchronously, and the movement of the air column 701 pushes the first air cylinder 702 to move through the first compression spring. When the first air cylinder 702 moves, it pushes the L-shaped rotating frame 703 to contact the exposure platform 9. When the L-shaped rotating frame 703 contacts the exposure platform 9, the second motor 601 stops working, the air column 701 stops moving, the first compression spring is not squeezed, the T-shaped shaft 616 contacts but does not squeeze the sealing plug 902, and the circuit board is located directly below the extreme purple lamp 2. At this time, the extreme purple lamp 2 is started, and the extreme purple lamp 2 irradiates parallel ultraviolet light to cause a chemical reaction in the exposure film, which adheres to the circuit board, thereby realizing the flipping exposure of the circuit board.

[0049] Then, the second motor 601 is started again, so that the flipping mechanism 6 executes the operation of moving backward again and rotating the circuit board again, so that the circuit board rotates 180° and resets, and the first motor 301 is started again. The first motor 301 controls the suction cup mechanism 7 to move away from the exposure platform 9 and moves the suction cup mechanism 7 toward the discharge port 102. When the suction cup mechanism 7 is located on the conveyor belt 8 of the discharge port 102, the first motor 301 stops working; ... The second forward movement is performed to move the positioning frame 710 to the top of the conveyor belt 8, and the T-shaped shaft 616 slides into the groove 801 of the conveyor belt 8 to prevent the T-shaped shaft 616 from colliding, and the positioning shaft 608 slides forward to make the L-shaped rotating frame 703 contact the conveyor belt 8, and then the suction cup mechanism 7 performs the action of moving the soft rubber suction cup 712 downward again to place the circuit board on the conveyor belt 8, and then the positioning shaft 608 continues to slide forward so that the suction cup mechanism 7 no longer absorbs the circuit board, thereby completing the circuit board placement action; the second movement is started again. The second motor 601 rotates in the opposite direction, causing the flip mechanism 6 to move backward again, so that the T-axis 616 and the air column 701 move backward. On the one hand, the T-axis 616 moves backward to slide out of the groove 801 of the conveyor belt 8. On the other hand, the positioning shaft 608 moves backward to cause the suction cup mechanism 7 to move the soft glue suction cup 712 upward again. At this time, the suction force of the cavity between the soft glue suction cup 712 and the circuit board is not enough to lift the circuit board against gravity, and the suction cup mechanism 7 completes the height reset; start the conveyor belt at the discharge port 102 8 causes the circuit board to be transported out of the shell 1, and the first motor 301 is started to reverse. The output shaft of the first motor 301 rotates to drive the first screw rod 302 to rotate. When the first screw rod 302 rotates, the sliding table 306 is driven to slide axially through the first threaded sleeve 304 to approach the conveyor belt 8 at the feed inlet 101. The movement of the sliding table 306 drives the first vertical plate 4 and the second vertical plate 5 to move synchronously, so that the first vertical plate 4 and the second vertical plate 5 drive the flipping mechanism 6 to move, and the movement of the flipping mechanism 6 causes the suction cup mechanism 7 to move synchronously, thereby completing the reset.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
