Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0025] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0026] As Figures 1-4 shown, an embodiment of the present utility model provides a PCBA board turning and feeding device, including a turning component 1. The turning component 1 includes a conveyor 11, a U-shaped frame 12, a central shaft 13, a turning motor 14, a connecting cylinder 15, a suction cylinder 16, a suction plate 17, suction nozzles 18, a connecting head 19, a suction hose 20, a suction pump 21, and a feeding component 2.

[0027] On both sides of the rear surface of the conveyor 11, a U-shaped frame 12 is fixedly connected. A central shaft 13 penetrates through the upper part of one side of the U-shaped frame 12. A turning motor 14 is fixedly connected to the outside of the U-shaped frame 12 near the central shaft 13 on one side. One end of the central shaft 13 is fixedly connected to the output end of the turning motor 14. In the middle of the outer sidewall of the central shaft 13, a connecting cylinder 15 is fixedly connected. In the middle of the outer sidewall of the connecting cylinder 15, a suction cylinder 16 is fixedly connected. One end of the suction cylinder 16 far from the connecting cylinder 15 communicates with a suction plate 17. A plurality of suction nozzles 18 are arranged at the bottom of the suction plate 17. One side of the outer sidewall of the suction cylinder 16 near the connecting cylinder 15 communicates with a suction hose 20 through a connecting head 19. One end of the suction hose 20 far from the connecting head 19 communicates with a suction pump 21. At the top of the rear surface of the U-shaped frame 12, a feeding component 2 is fixedly connected. The suction pump 21 provides negative pressure to the suction cylinder 16 through the suction hose 20 and the connecting head 19, so that a plurality of suction nozzles 18 at the bottom of the suction plate 17 generate suction force, so that the suction nozzles 18 firmly adsorb the PCBA board located in the turning area. By driving the central shaft 13 to rotate by the turning motor 14, the suction cylinder 16 on the connecting cylinder 15 is driven to rotate, and then the suction plate 17 and the PCBA board adsorbed by the suction nozzles 18 are driven to rotate for the turning action.

[0028] In one embodiment, specifically: the feeding component 2 includes side plates 22, a driving shaft 23, a driving roller 24, a driven shaft 25, a driven roller 26, a transmission belt 27, and a conveying motor 28.

[0029] On both sides of the top of the rear surface of the U-shaped frame 12, side plates 22 are fixedly connected. A driving shaft 23 penetrates through the rear part of one side of the two side plates 22. On both sides of the middle part of the outer side wall of the driving shaft 23, driving rollers 24 are fixedly connected. On the front part of the side of the two side plates 22 close to each other, driven shafts 25 are welded. On the outer side walls of the two driven shafts 25, driven rollers 26 are rotatably connected. The outer side wall of the driving roller 24 is rotatably connected to the outer side wall of the driven roller 26 through a transmission belt 27. On the rear part of the side of one side plate 22 away from the driving roller 24, a conveyor motor 28 is fixedly connected. One end of the driving shaft 23 is fixedly connected to the output end of the conveyor motor 28. By driving the driving shaft 23 to rotate through the conveyor motor 28, the two driving rollers 24 are driven to rotate, and then the two transmission belts 27 supported by the two driven rollers 26 are driven to move synchronously, and then the PCBA board flipped onto the two transmission belts 27 is driven to move.

[0030] In one embodiment, specifically: on both sides of the rear part of the inner side wall of the conveyor 11, first photoelectric sensors 29 are provided. On the rear part of one side of the conveyor 11, a controller 30 is fixedly connected. The output end of the first photoelectric sensor 29 is electrically connected to the input end of the controller 30. The input ends of the conveyor 11, the flap motor 14, and the suction pump 21 are all electrically connected to the output end of the controller 30. By the first photoelectric sensor 29, it is convenient to detect the PCBA board transmitted to the flipping area through the conveyor 11 and send a signal to the controller 30.

[0031] In one embodiment, specifically: on the upper part close to the transmission belt 27 on the front part of the side of the two side plates 22 close to each other, second photoelectric sensors 31 are provided. The output end of the second photoelectric sensor 31 is electrically connected to the input end of the controller 30. The input end of the conveyor motor 28 is electrically connected to the output end of the controller 30. By the second photoelectric sensor 31, it is convenient to detect the PCBA board flipped onto the transmission belt 27 and transmit a signal to the controller 30.

[0032] In one embodiment, specifically: on the middle part of the side of the two side plates 22 close to each other, a plurality of support shafts 32 are welded. On the outer side walls of the support shafts 32, support rollers 33 are rotatably connected. The inner side wall of the transmission belt 27 is rotatably connected to the outer side wall of the support roller 33. Through the support of the transmission belt 27 by the support rollers 33 rotating on the support shafts 32, the stability of the transmission of the transmission belt 27 is increased.

[0033] In one embodiment, specifically: annular limiting grooves 34 are opened in the middle parts of the outer side walls of the driving roller 24, the driven roller 26, and the support roller 33. A limiting strip 35 is fixedly connected to the middle part of the inner side wall of the transmission belt 27. The outer side wall of the limiting strip 35 is rotatably connected to the inner side wall of the annular limiting groove 34. By the limiting strip 35 on the transmission belt 27 rotating inside the annular limiting groove 34, the limiting strip 35 is limited, and then the stability of the rotation of the transmission belt 27 is increased.

[0034] In one embodiment, specifically: a touch screen 36 is provided on a side of the controller 30 away from the conveyor 11, and a man-machine interaction interface is provided through the touch screen 36 on the controller 30, so that an operator can monitor the operating state of the device, adjust parameters or perform fault diagnosis through the touch screen 36.

[0035] In one embodiment, specifically: support frames 37 are fixedly connected to the front part of the lower surface of the conveyor 11 and the rear parts of the lower surfaces of the two side plates 22. By supporting the conveyor 11 and the side plates 22 through the support frames 37, the stability of the entire device is improved.

[0036] When the present utility model is working: when the first optoelectronic sensor 29 detects that the PCBA board on the conveyor 11 is transmitted to the flipping area, and sends a signal to the controller 30 as an initial signal for triggering the flipping action. After receiving the signal from the first optoelectronic sensor 29, the controller 30 will immediately start the flipping motor 14 and the suction pump 21. The flipping motor 14 drives the connecting cylinder 15 and the suction cylinder 16 to rotate forward to a predetermined flipping position through the central shaft 13, so that the suction nozzles 18 are attached to the PCBA board on the conveyor 11 to prepare for the flipping action. At the same time, the suction pump 21 provides negative pressure to the suction cylinder 16 through the suction hose 20 and the connector 19, so that a plurality of suction nozzles 18 at the bottom of the suction disc 17 generate suction force, and the suction nozzles 18 firmly adsorb the PCBA board located in the flipping area. After the PCBA board is stably adsorbed, the flipping motor 14 drives the central shaft 13 to rotate reversely by 180°, thereby driving the PCBA board adsorbed by the suction cylinder 16 and the suction nozzles 18 on the suction disc 17 to rotate reversely by 180° for a flipping action, so as to flip the PCBA board from the conveyor 11 to the conveyor belt 27 on the board feeding assembly 2. At this time, the second optoelectronic sensor 31 detects the PCBA board on the conveyor belt 27 and sends a signal to the controller 30. The controller 30 automatically stops the operation of the suction pump 21, and the suction nozzles 18 release the PCBA board. The flipping motor 14 continues to drive the central shaft 13 to rotate, and drives the suction cylinder 16 and the suction disc 17 to continue to rotate reversely by 30°, so that the suction nozzles 18 are separated from the PCBA board on the conveyor belt 27. At the same time, the conveyor motor 28 is started to drive the driving shaft 23 to rotate, and the driving roller 24 is driven to rotate through the driving shaft 23, thereby driving the conveyor belt 27 to move. As the conveyor belt 27 moves, the PCBA board on the conveyor belt 27 is sent to the next process.

[0037] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
