[0028] like Figure 6-Figure 9 As shown, the driving assembly includes a driving shaft 61, a full gear 62, a rack 63 and an electric push rod 71. The driving shaft 61 is rotatably connected to the upper side of the inner part of the outer frame 4. A servo motor is bolted to the outer frame 4. The output shaft of the servo motor is fixedly connected to the driving shaft 6. A full gear 62 is coaxially connected to the middle part of the driving shaft 61. A rack 63 meshing with the full gear 62 is connected to the top of the translation plate 7. Two electric push rods 71 ​​are installed on the top of the push plate 6, and the telescopic rods of the two electric push rods 71 ​​are fixedly connected to the translation plate 7.

[0029] like Figure 4-Figure 9As shown, the transmission assembly includes a rack 2 81, a rotating shaft 82, a one-way gear 1 83, a one-way gear 2 84, a full gear 2 85 and a rack 3 86. A pair of racks 2 81 are welded to the left and right parts of the translation plate 7. The upper side of the inner part of the outer frame 4 is symmetrically connected to the rotating shaft 82 for rotation. The rear part of the rotating shaft 82 is connected to the one-way gear 1 83 through a one-way clutch, and the front part of the rotating shaft 82 is connected to the one-way gear 2 84 through a one-way clutch. The one-way gear 2 84 is meshed with the rack 2 81. When the translation plate 7 slides backward, The one-way gear 2 84 is separated from the rack 2 81, while the one-way gear 1 83 is meshed with the rack 2 81; the front and rear ends of the rotating shaft 82 are coaxially connected with the full gear 2 85, and the front and rear sides of the lifting and loading frame 5 are connected with a pair of racks 3 86 respectively meshed with the full gear 2 85; the front and rear sides of the lifting and loading frame 5 are provided with three long holes 53 for the driving shaft 61 and the rotating shaft 82 to pass through, and each row of rollers 51 is arranged in sections, which can prevent the lifting and loading frame 5 from being blocked by the driving shaft 61 and the rotating shaft 82 during the lifting process.

[0030] like Figure 7 and Fig.10 As shown, the control component includes a full gear three 91 and a toothed block 92. The full gear three 91 is coaxially connected to the front and rear sides of the rotating plate 9. The toothed block 92 is symmetrically welded to the front and rear of the upper right side of the outer frame 4. When the rotating plate 9 moves right with the push plate 6, the full gear three 91 will engage with the toothed block 92, thereby causing the rotating plate 9 to rotate and open.

[0031] Initially, the intelligent mobile vehicle 3 has moved to the left side of the workbench 1 of one of the processes of the circuit board 21, and the one-way gear 2 84 is meshed with the rack 2 81. The servo motor is first controlled to rotate the drive shaft 61 counterclockwise, and the drive shaft 61 drives the full gear 1 62 to rotate counterclockwise. Under the meshing action of the full gear 1 62 and the rack 1 63, the rack 1 63, the translation plate 7, the rack 2 81, the push plate 6, the full gear 3 91 and the rotating plate 9 move to the right together. Since the one-way gear 2 84 is meshed with the rack 2 81, the rack 2 81 that moves rightward drives the one-way gear 2 84 to rotate counterclockwise. At this time, due to the action of the one-way clutch, the counterclockwise rotation The moving one-way gear 2 84 will not cause the rotating shaft 82 to rotate, and the right-moving push plate 6 can push the uppermost circuit board 21 to move to the right through the push portion 60, and the roller 51 can rotate on itself to reduce the friction force on the circuit board 21 when it moves; when the full gear 3 91 is engaged with the toothed block 92, the full gear 3 91 and the rotating plate 9 can rotate counterclockwise under the action of the toothed block 92, and the rotating plate 9 opens without blocking the right side of the circuit board 21. When the push plate 6 and the circuit board 21 pass through the material passage hole 41, the circuit board 21 is pushed onto the two conveyor belts 2, and the circuit board 21 is transported to the right by the conveyor belts 2 for processing.

[0032] Then, the servo motor is controlled to make the drive shaft 61 and the full gear 1 62 rotate clockwise. Similarly, the rack 1 63, the translation plate 7, the rack 2 81, the push plate 6, the full gear 3 91 and the rotating plate 9 move to the left together. The left-moving rack 2 81 drives the one-way gear 2 84 to rotate clockwise. At this time, the clockwise rotating one-way gear 2 84 will drive the rotating shaft 82 and the full gear 2 85 to rotate clockwise together. Since the full gear 2 85 is meshed with the rack 3 86, the rack 3 86 can be raised, thereby The lifting loading frame 5 and the roller 51 are raised, so that the second layer of circuit boards 21 are raised to a height aligned with the material passing hole 41 and the pushing part 60. Under the action of the toothed block 92, the full gear 91 and the rotating plate 9 that move left will rotate clockwise to reset; the servo motor is controlled again to make the drive shaft 61 rotate counterclockwise. Similarly, the pushing part 60 can push the second layer of circuit boards 21 to the right to move onto the conveyor belt 2 for loading. This reciprocating process can convey the circuit boards 21 to the processing step for processing.

[0033] When it is necessary to collect the circuit boards 21 processed in this process, the electric push rod 71 is controlled to drive the translation plate 7 to move backward, driving the rack 1 63 and the rack 2 81 to move backward, so that the one-way gear 2 84 is separated from the rack 2 81, and the one-way gear 1 83 is meshed with the rack 2 81; when the servo motor is controlled to make the drive shaft 61 and the full gear 1 62 rotate counterclockwise, the rack 1 63, the translation plate 7, the rack 2 81, the push plate 6, the full gear 3 91 and the rotating plate 9 moves to the right. Since the one-way gear 1 83 is meshed with the rack 2 81, the rack 2 81 moving to the right drives the one-way gear 1 83 to rotate counterclockwise. At this time, the one-way gear 2 84 rotating counterclockwise drives the rotating shaft 82 and the full gear 2 85 to rotate counterclockwise, thereby lowering the rack 3 86, the lifting loading frame 5 and the roller 51. Similarly, the full gear 3 91 moving to the right causes the rotating plate 9 to rotate and open, and the conveyor belt 2 can transport the circuit board 21 to the left onto the roller 51.

[0034] Then the servo motor is controlled to make the driving shaft 61 and the full gear 1 62 rotate clockwise, the rack 1 63, the translation plate 7, the rack 2 81, the push plate 6, the full gear 3 91 and the rotating plate 9 move to the left, and the left-moving rack 2 81 drives the one-way gear 1 83 to rotate clockwise. At this time, due to the action of the one-way clutch, the clockwise rotating one-way gear 1 83 will not rotate the rotating shaft 82. When the rotating plate 9 rotates clockwise to reset, the left-moving rotating plate 9 can push the circuit board 21 into the lifting loading frame 5, and the block portion 52 limits the pushed circuit board 21; this reciprocating process can collect the circuit boards 21 processed in this process.

[0035] The intelligent mobile vehicle 3 is controlled to move to the left of the workbench 1 of the next process, so that the material can be loaded in the next process. The loading and collection process of the circuit board 21 is automated, and can automatically cooperate with different processes to improve the processing efficiency of the circuit board 21.

[0036] Embodiment 2: Based on embodiment 1, Figure 1 As shown, it also includes a guide rod 10. The guide rod 10 for guiding the intelligent mobile vehicle 3 is symmetrically welded on the front and back of the left side of the workbench 1. The left section of the guide rod 10 is inclined, and the distance between the two left sections of the guide rods 10 gradually increases from right to left; when the intelligent mobile vehicle 3 moves to the left side of the workbench 1 of the next process, the two guide rods 10 can guide the intelligent mobile vehicle 3 so that the material passing hole 41 can be aligned with the conveyor belt 2 to avoid position deviation of the intelligent mobile vehicle 3.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
