[0007] A push plate is fixedly connected to the slider. A limiting component is arranged on the support seat. The limiting component includes a limiting plate that cooperates with the push plate. The limiting plate is fixedly connected to the support seat, and the limiting plate is arranged below the outlet end of the conveyor belt;

[0008] Two guide rails are fixedly connected to the support base. A sliding seat is slidably connected to the two guide rails. A plurality of collection components are arranged on the sliding seat. Each collection component includes two support rods, two second springs, and a storage frame. Each support rod is slidably connected to the sliding seat. One end of each second spring is fixedly connected to the sliding seat, and the other ends of the two second springs are respectively fixedly connected to the corresponding support rods. The upper end of each support rod is fixedly connected to the storage frame.

[0009] As a preferred solution, one end of the sliding rod is fixedly connected with an inclined block with a right-angled triangle cross-section.

One end of the cross bar is fixedly connected with a moving block with a concave-shaped cross-section.

[0011] As a preferred solution, a groove with an isosceles trapezoid cross-section is formed on the support base. The moving block is slidably connected to the groove.

Detailed implementation manner

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Refer to Figures 1 - 6 , an ink curing and drying machine for circuit board production, including a support frame 1, a conveyor belt 2 and a fixed shell 3. A plurality of ultraviolet lamps and a first fan are arranged inside the fixed shell 3. A support seat 8 is fixedly connected to the support frame 1. A sliding rod 15 is connected to the support seat 8 through a first spring 16. One end of the first spring 16 is fixedly connected to the surface of the support seat 8, and the other end of the first spring 16 is fixedly connected to the sliding rod 15. A slider 31 is slidably connected to the support seat 8. A rotating rod 20 is hinged to the slider 31. The rotating rod 20 is hinged to the sliding rod 15. A push plate 17 is fixedly connected to the slider 31. A limiting component is arranged on the support seat 8. The limiting component includes a limiting plate 14 that cooperates with the push plate 17. The limiting plate 14 is fixedly connected to the support seat 8. The limiting plate 14 is arranged below the outlet end of the conveyor belt 2.

[0028] Two guide rails 7 are fixedly connected to the support seat 8. A sliding seat 6 is slidably connected to the two guide rails 7. A plurality of collecting components are arranged on the sliding seat 6. Each collecting component includes two support rods 5, two second springs 9 and a storage box 4. Each support rod 5 is slidably connected to the sliding seat 6. One end of each second spring 9 is fixedly connected to the sliding seat 6, and the other ends of the two second springs 9 are respectively fixedly connected to the corresponding support rods 5. The upper end of each support rod 5 is fixedly connected to the storage box 4.

[0029] One end of the sliding rod 15 is fixedly connected to an inclined block 21 with a cross-section in a right triangle shape. A servo motor is installed on one side of the support seat 8. The driving end of the servo motor is fixedly connected to a rotating shaft 22. A cam 25 is fixedly connected to the rotating shaft 22. During the rotation of the cam 25, the inclined surface of the inclined block 21 will be extruded, causing it to move, thereby driving the sliding rod 15 to slide relative to the support seat 8, and the first spring 16 deforms.

[0030] One side of the support base 8 is fixedly connected with a mounting plate 29 with a concave cross-section. A cross bar 24 is slidably connected to the mounting plate 29. A third spring 28 is sleeved on the cross bar 24. One end of the third spring 28 is fixedly connected to the cross bar 24, and the other end of the third spring 28 is fixedly connected to the mounting plate 29. One end of the cross bar 24 is fixedly connected with a moving block 30 with a concave cross-section. A groove 27 with an isosceles trapezoid cross-section is formed in the support base 8. The moving block 30 is slidably connected with the groove 27. Two symmetrically arranged bent rods 26 are slidably connected to the moving block 30. One ends of the two bent rods 26 respectively abut against the inclined surfaces of the groove 27. A fourth spring 33 is fixedly connected to each bent rod 26. The fourth spring 33 is fixedly connected to the moving block 30. A clamping plate 13 is fixedly connected to each bent rod 26.

[0031] One end of the cross bar 24 away from the moving block 30 is fixedly connected with a first magnet 23. A second magnet is fixedly connected to one side surface of the cam 25. The magnetic poles of the second magnet and the first magnet 23 facing each other are the same. During the rotation of the cam 25 together with the rotating shaft 22, when the second magnet faces the first magnet 23, there is a repulsive force between the first magnet 23 and the second magnet. Under the action of the repulsive force, the first magnet 23 and the cross bar 24 move away from the cam 25 at the same time, and the third spring 28 deforms. During the movement of the moving block 30, one ends of the two bent rods 26 will respectively abut against the two inclined inner walls of the groove 27 and move, and the fourth spring 33 deforms, and the distance between the two clamping plates 13 will decrease.

[0032] A limiting block 18 is fixedly connected to one side surface of each storage box 4. A baffle 19 is fixedly connected to one side of the support base 8. The surface of one of the limiting blocks 18 is attached to the surface of the baffle 19. A plurality of second fans 11 are arranged on the support base 8. An electric push rod 12 is installed on the support base 8. The driving end of the electric push rod 12 is fixedly connected with a pulling block 10. A plurality of slots 32 for connecting the limiting blocks 18 are formed in the pulling block 10. After the circuit board falls into the corresponding storage box 4, under the action of the gravity of the circuit board, the storage box 4 will move downward, and the two support rods 5 will slide relative to the sliding seat 6 at the same time, and the second spring 9 deforms.

[0033] After the storage box 4 moves downward, the limiting block 18 will move into the corresponding slot 32 on the pulling block 10. At this time, the electric push rod 12 operates, driving the pulling block 10 to move towards the direction close to the electric push rod 12 until the limiting block 18 on the next storage box 4 contacts the baffle 19. At this time, the electric push rod 12 stops operating, and the circuit board moves to the front side of the corresponding second fan 11, and the second fan 11 starts, which is beneficial to the heat dissipation of the circuit board.

[0034] In the present invention, during use, a circuit board (not shown) is conveyed on a conveyor belt 2. When the circuit board flows under a fixed housing 3, multiple ultraviolet lamps inside the fixed housing 3 can cure and dry the ink on the surface of the circuit board. Then, under the conveying action of the conveyor belt 2, the circuit board will continue to move. When the circuit board moves to one end of the conveyor belt 2, the circuit board will gradually separate from the conveyor belt 2. The circuit board will first move in a state of inclining downward. At the same time, a servo motor operates and drives a rotating shaft 22 to rotate. The rotating shaft 22 drives a cam 25 to rotate together. During the rotation of the cam 25, it will squeeze the inclined surface of an inclined block 21, causing it to move, thereby driving a sliding rod 15 and a support seat 8 to slide relative to each other. Since one end of a first spring 16 is fixedly connected to the sliding rod 15 and the other end of the first spring 16 is fixedly connected to the surface of the support seat 8, the first spring 16 is deformed.

[0035] During the movement of the sliding rod 15, the inclination angle of a rotating rod 20 also changes simultaneously, and a slider 31 will also slide relative to the support seat 8, thereby driving a push plate 17 to move together. When the push plate 17 moves in a direction close to a limiting plate 14, the push plate 17 will contact one side surface of the circuit board and push and straighten the circuit board until the other side surface of the circuit board fits against the surface of the limiting plate 14. Under the combined limiting action of the push plate 17 and the limiting plate 14, the circuit board can be in a vertical state. Then, after the cam 25 and the inclined block 21 are separated, under the elastic force of the first spring 16, the sliding rod 15 will return to its initial position. After the push plate 17 moves and separates from the surface of the circuit board, the circuit board moves downward under the action of gravity.

[0036] During the process of the cam 25 rotating together with the rotating shaft 22, a second magnet rotates simultaneously. The second magnet has a larger area than a first magnet 23. When the second magnet on the surface of the cam 25 faces the first magnet 23 on the surface of a moving block 30, since the magnetic poles of the first magnet 23 and the second magnet facing each other are the same, there is a repulsive force between the first magnet 23 and the second magnet. Under the action of the repulsive force, the first magnet 23 and a cross bar 24 move away from the cam 25 at the same time. During the relative sliding of the cross bar 24 and a mounting plate 29, a third spring 28 is deformed. During the process of the cross bar 24 driving the moving block 30 to move together, one ends of two bending rods 26 respectively abut against the two inclined inner walls of a groove 27 and move. The bending rods 26 also slide relative to the moving block 30 at the same time, and a fourth spring 33 is deformed.

[0037] After the two bent rods 26 and the moving block 30 slide relative to each other, the clamping plates 13 connected to the two bent rods 26 move simultaneously, and the distance between the two clamping plates 13 decreases simultaneously. The two clamping plates 13 are located below the limiting plate 14 and the pushing plate 17. During the movement of the two clamping plates 13, they will respectively fit against the two side surfaces of the circuit board. Under the clamping and pushing action of the two clamping plates 13, the circuit board can be straightened to keep it in a vertical state, avoiding the circuit board from tilting during the falling process. After that, part of the circuit board will fall into the interior of the storage frame 4, and under the short-term clamping action of the two clamping plates 13, the speed of the bottom of the circuit board when it falls into the interior of the storage frame 4 can be reduced, thereby slowing down the impact collision between the circuit board and the storage frame 4 and preventing the circuit board from being damaged, which is beneficial to the subsequent use of the circuit board.

[0038] After the circuit board falls into the corresponding storage frame 4, under the action of the gravity of the circuit board, the storage frame 4 will move downward. The two support rods 5 slide relative to the sliding seat 6 simultaneously, and the second spring 9 deforms. One side surface of the limiting block 18 on one side of the storage frame 4 is initially in contact with the surface of the baffle 19. After the storage frame 4 moves downward, the limiting block 18 will move into the corresponding slot 32 on the pulling block 10. At this time, the electric push rod 12 operates to drive the pulling block 10 to move in the direction close to the electric push rod 12 until the limiting block 18 on the next storage frame 4 contacts the baffle 19, and then the electric push rod 12 stops operating. Repeat the above process. When the circuit board separated from the conveyor belt 2 falls into the next storage frame 4, the electric push rod 12 will drive the pulling block 10 to move again until the next empty storage frame 4 is located between the two clamping plates 13, and the circuit boards are vertically placed in each storage frame 4, which is beneficial to saving the space occupied by the circuit boards. There are relatively large gaps between the storage frames 4 to facilitate the heat dissipation of the circuit boards. The storage frames 4 can be set as hollowed-out to facilitate better heat dissipation of the circuit boards.

[0039] Under the driving action of the electric push rod 12, the storage frame 4 containing the circuit board will move to the side of the second fan 11 in sequence. When the infrared region corresponding to the second fan 11 is blocked by the circuit board, the second fan 11 operates (the working principle of the second fan 11 is similar to that of an induction faucet), thereby accelerating the heat dissipation and cooling of the circuit board. When there is no circuit board in front of part of the second fan 11, the second fan 11 does not operate, which is beneficial to saving energy and is more energy-saving and environmentally friendly to use.

[0040] When the circuit board above the sliding seat 6 is cooled, the sliding seat 6 can be taken out from the guide rail 7. The circuit boards are neatly arranged in each storage frame 4 in sequence. It is not necessary for the staff to manually sort and arrange each circuit board, and they can be directly stored. The operation is relatively convenient and fast, greatly shortening the processing time, which is beneficial to the use of the device.

[0041] As described above, it is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
