[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 12 As shown in this embodiment, an automatic flipping device includes a device support 1, an upper conveying track 2, a lower conveying track 3, and a flipping base plate 4. The upper conveying track 2 is located directly above the lower conveying track 3. The flipping base plate 4 is installed on the rear side of the device support 1. A lifting linear module 5 is provided on the flipping base plate 4. A carrier plate 6 is connected to the driving end of the lifting linear module 5. A clamping flipping component 7 is provided on the outer side of the carrier plate 6. A flipping fixture 8 is clamped between the two clamping flipping components 7. A pushing component 9 is provided above the flipping fixture 8.

[0033] After the circuit board is positioned on one of the fixture plates 31 of the flipping fixture, it is placed on the upper conveyor rail 2. The upper conveyor rail 2 moves the flipping fixture below the carrier plate 6. The lifting linear module 5 moves down, driving the other fixture plate 31 to move down. After the two fixture plates 31 are combined, the clamping flipping assembly flips the upper and lower fixture plates 31. The pushing assembly 9 pushes the circuit board from the upper fixture plate 31 down to the lower fixture plate 31. Then the lifting linear module 5 puts the lower fixture plate 31 back into the upper conveyor rail 2 for conveying, completing the flipping operation. After the circuit board is removed, the empty fixture plate 31 is returned from the lower conveyor rail 3 for continued use.

[0034] The specific structure is as follows:

[0035] Each clamping and flipping assembly 7 is equipped with a clamping cylinder 10 and a transverse slide rail 11. The driving end of the clamping cylinder 10 is connected to a clamping plate 12. The upper end of the clamping plate 12 moves along the transverse slide rail 11. The lower end of the clamping plate 12 is equipped with a fixture clamping protrusion 13, which is locked at the end of the flipping fixture 8.

[0036] The clamping cylinder 10 controls the clamping plate 12 to move left and right via the transverse slide rail 11. The clamping plates 12 on both sides work together to flip the flipping fixture 8 in the middle position.

[0037] A tilting cylinder 14 is installed at the outer end of one side clamping plate 12, and the driving end of the tilting cylinder 14 is connected to a tilting driven rod 15; a tilting motor 16 is installed at the upper end of the other side clamping plate 12, and a tilting shaft 17 is installed at the lower end of the other side clamping plate 12. The driving end of the tilting motor 16 and the outer end of the tilting shaft 17 are both connected to tilting synchronous pulleys 18. A tilting synchronous belt 19 is connected between the tilting synchronous pulleys 18. A tilting driving rod 20 is connected to the inner end of the tilting shaft 17; the fixture clamping protrusions 13 are distributed at both ends of the tilting driving rod 20 and both ends of the tilting driven rod 15.

[0038] The flipping cylinder 14 controls the flipping driven rod 15 to approach the flipping fixture 8, and pushes the flipping fixture 8 against the flipping active rod 20. The fixture clamping protrusion 13 is inserted into the fixture clamping hole 39 for fixation. The flipping motor 16 flips the flipping fixture 8 under the drive of the flipping synchronous pulley 18 and the flipping synchronous belt 19.

[0039] A flip sensor 21 is installed on the inner side of the clamping plate 12, and a flip sensor plate is fixed on the flip active rod 20. The flip sensor plate is connected to the flip sensor 21 for signal transmission. During the flipping process, the flip sensor 21 senses the flip sensor plate to determine whether the flipping is in place.

[0040] A fixture sensor 23 is installed on the inner side of the clamping plate 12. The fixture sensor 23 senses the flip fixture 8. Only when the fixture sensor 23 senses the flip fixture 8 will it drive the flip motor 16 to flip the surface, instead of running empty.

[0041] The flipping fixture 8 includes two fixture plates 31, which are combined along the vertical direction. A product clearance groove 32 is provided in the middle of the fixture plate 31, and a product limiting block 33 is provided on the outer side of the product clearance groove 32. A limiting adjustment groove 34 is provided on the fixture plate 31. One side of the product limiting block 33 is connected to the limiting adjustment groove 34, and a limiting step 35 or a PCB board positioning pin 36 is provided on the other side of the product limiting block 33. Fixture positioning pins 37 and fixture positioning holes 38 are provided on the side of the fixture plate 31. The positions of the fixture positioning pins 37 and the positions of the fixture positioning holes 38 are symmetrically distributed with respect to the center of the fixture plate 31. Fixture clamping holes 39 are provided at both ends of the fixture plate 31.

[0042] According to the size of the circuit board, adjust the position of the product limiting block 33 on the limiting adjustment groove 34 so that the current limiting step 35 corresponds to the outer edge of the circuit board, and the PCB board positioning pin 36 passes through the hole on the circuit board. Then lock the position of the product limiting block 33 on the limiting adjustment groove 34. With the upper and lower fixture plates 31 symmetrical, clamp the circuit board on the inner side. The fixture plate 31 is flipped by the positioning action of the fixture clamping hole 39. The fixture plate 31 that was originally in the lower position flips to the upper position. The circuit board that was originally in the lower fixture plate 31 will fall into the fixture plate 31 that is now in the lower position. When clamping the circuit board between the upper and lower fixture plates 31, the fixture positioning pin 37 is inserted into the fixture positioning hole 38 of the other fixture plate 31 to lock it.

[0043] The end of the jig plate 31 is provided with a jig stop 40, which is recessed inward. When the jig plate 31 drives the circuit board to be conveyed, the stop device on the conveying structure positions the jig stop 40 to facilitate the flipping operation.

[0044] A label card plate 41 is provided on the side of the jig plate 31. The label card plate 41 is locked to the jig plate 31 by screws. The information corresponding to the circuit board on the jig plate 31 can be obtained according to the markings on the label card plate 41.

[0045] The product limiting block 33 is provided with a nut groove 42, and a square nut 43 is placed in the nut groove 42. A bolt 44 is provided in the limiting adjustment groove 34. The bolt 44 passes through the limiting adjustment groove 34 and the product limiting block 33, and then is threadedly connected to the square nut 43. After loosening the bolt 44, the position of the product limiting block 33 on the limiting adjustment groove 34 can be adjusted, and the square nut 43 will be moved to the edge of the circuit board and then locked with the bolt 44.

[0046] The jig plate 31 is rectangular or cubic in shape. Of course, in other embodiments, the jig plate 31 can also be other symmetrical shapes to suit different product requirements.

[0047] The material pushing assembly 9 includes a material pushing fixed plate 24, which is fixedly connected to the carrier plate 6. A material pushing sleeve 25 and a material pushing cylinder 26 are installed on the material pushing fixed plate 24. The drive end of the material pushing cylinder 26 is vertically connected to a material pushing movable plate 27. A material pushing optical shaft 28 and a push rod 29 are fixed on the material pushing movable plate 27. The material pushing optical shaft 28 slides vertically on the material pushing sleeve 25. A spring 30 is connected between the push rod 29 and the material pushing movable plate 27.

[0048] In order to smoothly detach the circuit board from the original jig plate 31, the pusher cylinder 26 controls the pusher movable plate 27 to move downward, so that the pusher rod 29 pushes the circuit board from the jig plate 31 flipped up to the jig plate 31 flipped down, and makes elastic contact under the action of the spring 30, so as not to crush the circuit board.

[0049] Both the upper conveying track 2 and the lower conveying track 3 are equipped with track supports 45. An adjusting screw 46 and an adjusting optical shaft 47 are horizontally installed on the track supports 45. An adjusting handwheel 48 is installed at the end of the adjusting screw 46. A track fixing plate 49 is fixed on one side of the track supports 45, and a track movable plate 50 is provided on the other side of the track supports 45. An adjusting nut seat is installed at the lower end of the track movable plate 50. The adjusting nut seat is threadedly connected to the adjusting screw 46. The track movable plate 50 slides along the adjusting optical shaft 47.

[0050] Furthermore, a stop cylinder 51 is installed in the middle of the track support 45, with the drive end of the stop cylinder 51 pointing vertically upward. Track belts 52 and track motors 53 are installed on both the track fixed plate 49 and the track movable plate 50, with the drive end of the track motor 53 driving the rotation of the track belt 52.

[0051] When conveying the jig plate 31, the track motor 53 drives the track belt 52 to move the jig plate 31. The stop cylinder 51 controls the drive end to rise, blocking the position of the jig stop port 40. After limiting the position of the jig plate 31, the lifting plate 22 in the middle of the track support 45 lifts the jig plate 31, and it is combined with another jig plate 31 on the clamping and flipping assembly 7 above to flip it. The rotation of the adjustment handwheel 48 can be manually controlled according to the size of the jig plate 31. Under the drive of the adjustment screw 46, the track movable plate 50 changes the distance between itself and the track fixed plate 49 along the adjustment optical axis 47.

[0052] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
