Description

Technical Field

[0001] This invention relates to the field of circuit board production equipment, and more particularly to a circuit board processing and feeding device. Background Technology

[0002] As one of the basic components of electronic devices, circuit boards are where most of the electronic components or other electronic devices that enable the functions of electronic devices are located and rely on circuit boards for power supply and signal transmission.

[0003] During circuit board processing, a feeding device is needed to transport the circuit boards to the processing position. For example, patent application number CN202021098256.8 discloses a precision drilling device for printed circuit boards, which includes a feeding device. The PCB boards to be drilled are neatly stacked and placed on an operating table between four positioning plates. Motor I is started, driving lead screw I to rotate. Since lead screw I is threadedly connected to the pressure plate, when lead screw I rotates, the pressure plate moves downwards. The pressing mechanism below the pressure plate contacts the PCB board and fixes it. After the PCB board is fixed, cylinder I is started, the piston rod on cylinder I extends, and the push plate moves. The push plate contacts the bottommost PCB board on the pressure plate and pushes it to move. The bottommost PCB board moves to the designated position for processing. However, when the circuit boards are stacked, pushing the bottommost circuit board to the designated position for processing causes the weight of the circuit boards above it to act on the bottommost circuit board. Pushing the circuit board under this heavy pressure can easily scratch the circuit board.

[0004] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a circuit board processing and feeding device.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses a circuit board processing feeding device, comprising a frame, a rotary motor fixed on the frame, a turntable fixed to the output end of the rotary motor, and multiple feeding modules evenly fixed on the turntable. Each feeding module includes multiple positioning angle irons fixed on the turntable. A through hole penetrating the turntable is provided on the turntable at the corresponding position of each feeding module. A feeding motor is also fixed on the frame below the turntable, and a lead screw is fixed to the output end of the feeding motor. Multiple sliding rods are also fixed on the frame. A connecting plate threadedly connected to the lead screw is provided on the lead screw. The sliding rods pass through the connecting plate and are slidably connected to the connecting plate. A push plate cooperating with the through hole is also provided above the connecting plate. The push plate is fixed to the connecting plate by a connecting rod. A conveying device is also fixed on the frame on one side of the turntable. The conveying device includes two conveying shafts set on the frame. The conveying shafts are driven to rotate by a conveying motor. Conveying wheels are fixed at both ends of the conveying shafts. The conveying wheels at corresponding positions on the two conveying shafts are connected by conveying ropes. A feeding cylinder is also fixed on the frame at the position of the conveying device. A fixing plate is fixed to the end of the piston rod of the feeding cylinder. A support rod is also fixed below the fixing plate. A support tube is also provided on the support rod and rotatably connected to the support rod. A scraper is also fixed below the support tube. A positioning block that cooperates with the scraper is also fixed on the fixing plate.Stacked circuit boards to be processed are placed on each feeding module. The circuit boards are positioned around their perimeter by positioning angle irons. After the circuit boards are placed, the rotary motor starts, driving the turntable to rotate. When one feeding module on the turntable reaches above the push plate, the feeding motor starts again, driving the lead screw to rotate. The lead screw is threadedly connected to the connecting plate. When the lead screw rotates, the connecting plate moves in the direction of the lead screw, and the push plate moves with the connecting plate. After the push plate passes through the through hole, it pushes the circuit board at the corresponding position to rise. When the uppermost circuit board reaches the designated position, the feeding cylinder starts, and the piston rod on the feeding cylinder extends, moving the fixed plate. When the fixed plate moves, because the support tube on the support rod is rotatably connected to the support rod, the scraper contacts the circuit board and pushes the support tube to rotate around the support rod. The scraper moves above the circuit board. When the scraper separates from the circuit board, the scraper returns to a vertical state due to gravity. The feeding cylinder starts again, and the piston rod on the feeding cylinder shortens, moving the scraper with the fixed plate. With a fixed positioning block, the scraper contacts the topmost circuit board and pushes it to move. The circuit board moves to the conveyor position, and after both ends of the circuit board reach the conveyor rope, it rotates with the conveyor rope to the designated position for processing. This cycle repeats, allowing each circuit board to be divided into individual pieces and conveyed to the conveyor position, and then transported to the processing position by the conveyor rope. When all the circuit boards in a feeding module are conveyed to the conveyor position, the feeding motor drives the lead screw to rotate in the opposite direction. The lead screw rotates in the opposite direction, the connecting plate descends, the push plate descends, and after the push plate descends below the turntable, the rotary motor drives the turntable to rotate. The next feeding module on the turntable reaches the push plate, and the cycle repeats. This device can divide circuit boards into individual pieces and convey them to the designated position. When pushing the circuit boards, the topmost circuit board moves to the conveyor position, which can effectively avoid the weight of multiple circuit boards stacked on top of the circuit board that needs to be moved, and prevent the circuit board from being scratched by pressure during movement.

[0008] Preferably, the feeding module further includes multiple positioning rods fixed on the turntable, and the feeding module also includes a tray. The positioning rods pass through the tray at corresponding positions and are slidably connected to the tray. When placing the circuit board, the circuit board is placed on the tray, and a pusher plate pushes the tray upward, avoiding direct force exerted on the circuit board by the pusher plate, which could cause the circuit board to deform under stress.

[0009] Preferably, the support rod is further provided with a torsion spring, one end of which is fixed to the support rod and the other end of which is fixed to the support tube.

[0010] Preferably, a feeding cylinder is also fixed on the frame at the location of the conveying device. A feeding plate is fixed to the end of the piston rod of the feeding cylinder, and a support plate is also fixed to the feeding plate. When the scraper pushes the circuit board to move, the circuit board first moves to the support plate and slides from the support plate to the position of the conveyor rope. When the turntable needs to rotate, the feeding cylinder is activated, the piston rod on the feeding cylinder shortens, and the support plate moves away from the turntable, avoiding collision between the support plate and the positioning angle iron, and ensuring that the circuit board moves smoothly to the position of the conveyor rope.

[0011] Compared with existing technologies, the present invention has the following advantages:

[0012] This device can divide circuit boards into individual components and transport them to designated locations. When pushing circuit boards, the topmost circuit board moves to the conveyor position, which can effectively avoid the weight of multiple circuit boards stacked on the circuit board that needs to be moved, and prevent the circuit board from being scratched by pressure. Furthermore, by setting multiple feeding modules, continuous feeding of circuit boards can be achieved. Attached Figure Description

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0019] Example 1:

[0020] like Figures 1 to 3As shown, this embodiment discloses a circuit board processing feeding device, including a frame 1, a rotary motor 2 fixed on the frame 1, a turntable 3 fixed at the output end of the rotary motor 2, a plurality of feeding modules 4 evenly fixed on the turntable 3, each feeding module 4 including a plurality of positioning angle irons 5 fixed on the turntable 3, and through holes 6 provided on the turntable 3 at corresponding positions of the feeding modules 4. A feeding motor 9 is also fixed on the frame 1 below the turntable 3, a lead screw 11 is fixed at the output end of the feeding motor 9, and a plurality of sliding rods 10 are also fixed on the frame 1. A connecting plate 12 threadedly connected to the lead screw 11 is provided on the lead screw 11, and the sliding rods 10 pass through the connecting plate 12 and are slidably connected to the connecting plate 12. A push plate 14 cooperating with the through holes 6 is also provided above the connecting plate 12. 4. The connecting rod 13 is fixed to the connecting plate 12. A conveying device is also fixed on the frame 1 on one side of the turntable 3. The conveying device includes two conveying shafts 22 set on the frame 1. The conveying shafts 22 are driven to rotate by the conveying motor 23. Conveying wheels 24 are fixed at both ends of the conveying shafts 22. The conveying wheels 24 at corresponding positions on the two conveying shafts 22 are connected by conveying ropes 25. A feeding cylinder 15 is also fixed on the frame 1 at the position of the conveying device. A fixing plate 16 is fixed at the end of the piston rod of the feeding cylinder 15. A support rod 17 is also fixed below the fixing plate 16. A support tube 19 is also provided on the support rod 17 and rotatably connected to the support rod 17. A scraper 18 is also fixed below the support tube 19. A positioning block 21 that cooperates with the scraper 18 is also fixed on the fixing plate 16.Stacked circuit boards to be processed are placed on each feeding module 4. The circuit boards are positioned around their perimeter by positioning angle irons 5. After the circuit boards are placed, the rotary motor 2 is started, driving the turntable 3 to rotate. When one of the feeding modules 4 on the turntable 3 reaches above the push plate 14, the feeding motor 9 is started, driving the lead screw 11 to rotate. The lead screw 11 is threadedly connected to the connecting plate 12. When the lead screw 11 rotates, the connecting plate 12 moves in the direction of the lead screw 11, and the push plate 14 moves with the connecting plate 12. After passing through the through hole 6, the push plate 14 pushes the circuit board at the corresponding position. As the circuit board rises and reaches its designated position, the feeding cylinder 15 is activated, extending its piston rod and causing the fixed plate 16 to move. During this movement, the support tube 19 on the support rod 17 is rotatably connected to the support rod 17. The scraper 18 then contacts the circuit board, pushing the support tube 19 to rotate around the support rod 17, causing the scraper 18 to move above the circuit board. Once the scraper 18 separates from the circuit board, it returns to a vertical position due to gravity. The feeding cylinder 15 is then activated again, shortening its piston rod and causing the scraper 18 to move along with the fixed plate 16. The movement is achieved by fixing a positioning block 21 on the fixed plate 16 on one side of the scraper 18. Due to the obstruction of the positioning block 21, the scraper 18 contacts the uppermost circuit board, pushing it to move. The circuit board moves to the conveyor position, and after both ends reach the conveyor rope 25, it rotates with the conveyor rope 25 to the designated position for processing. This cyclical operation can separate the circuit boards into individual pieces and transport them to the conveyor position, where they are then conveyed to the processing position by the conveyor rope 25. When all the circuit boards in one loading module 4 have been transported to the conveyor position, the loading motor 9 drives... When the lead screw 11 rotates in the reverse direction, the connecting plate 12 descends, and the push plate 14 descends. After the push plate 14 descends below the turntable 3, the rotary motor 2 drives the turntable 3 to rotate. The next feeding module 4 on the turntable 3 reaches the top of the push plate 14, and the cycle continues. This device can divide the circuit board into individual components and transport them to the designated position. When the circuit board is pushed to move, the topmost circuit board moves to the position of the conveying device, which can effectively avoid the weight of multiple circuit boards stacked on top of the circuit board that needs to be moved, and prevent the circuit board from being scratched by pressure.

[0021] The feeding module 4 also includes multiple positioning rods 7 fixed on the turntable 3, and a tray 8. The positioning rods 7 pass through the tray 8 at corresponding positions and are slidably connected to the tray 8. When placing the circuit board, the circuit board is placed on the tray 8, and the tray 8 is pushed up by the push plate 14, which avoids the push plate 14 directly acting on the circuit board and causing the circuit board to deform due to force.

[0022] The support rod 17 is also equipped with a torsion spring 20. One end of the torsion spring 20 is fixed to the support rod 17, and the other end of the torsion spring 20 is fixed to the support tube 19.

[0023] Example 2:

[0024] This embodiment discloses a circuit board processing feeding device. Based on the structure and principle of Embodiment 1, this embodiment further includes a feeding cylinder 26 fixed on the frame 1 at the conveying device position. A feeding plate 27 is fixed to the end of the piston rod of the feeding cylinder 26, and a support plate 28 is fixed on the feeding plate 27. When the scraper 18 pushes the circuit board to move, the circuit board first moves to the support plate 28 and slides from the support plate 28 to the position of the conveying rope 25. When the turntable 3 needs to rotate, the feeding cylinder 26 is activated, the piston rod of the feeding cylinder 26 shortens, and the support plate 28 moves away from the turntable 3, avoiding collision between the support plate 28 and the positioning angle iron 5, and ensuring that the circuit board moves smoothly to the position of the conveying rope 25.

[0025] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention. These changes, modifications, substitutions and variations should also be considered within the scope of protection of the present invention.
