Description

Technical Field

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

[0002] When processing circuit boards, a feeding device is needed to separate the stacked circuit boards into individual pieces and supply them to the machine for processing.

[0003] Patent application number CN202322244506.4 discloses a circuit board loading device, including a table fixed to a machine frame. Four angle irons are fixed on the table, and a sliding groove penetrating the table is also provided. A push plate is also provided on the table at the location of the sliding groove, and a slider is provided below the table. Circuit boards to be processed are stacked between the angle irons, with the bottom layer of circuit boards on the table. After the push plate contacts the circuit boards, it pushes the bottom layer of circuit boards to move and supply them to the machine. However, this type of device, by stacking the circuit boards between the angle irons, cannot accommodate a large number of circuit boards due to the height limitation of the angle irons. This results in workers needing to replenish the circuit boards between the angle irons in a short period of time.

[0004] This invention was developed to address 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 feeding device for circuit board processing.

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

[0007] This invention discloses a feeding device for circuit board processing, comprising a frame, a table fixed on the frame, a turntable rotatably connected to the table, the turntable being driven to rotate by a rotary motor, and multiple positioning devices evenly fixed on the turntable, each positioning device comprising multiple positioning rods fixed to the turntable. A vertical plate is fixed on the table, and multiple cylinders are fixed on the vertical plate. A push plate is also provided on one side of the vertical plate, and the piston rod ends of each cylinder are fixed to the push plate. The frame on one side of the table is also fixed with... Angle iron is provided, and a limit plate is fixed on the frame at each angle iron position. A rotating shaft is provided on the frame between the limit plate and the corresponding angle iron position. The rotating shaft is driven by a limit motor. A limit roller is fixed on each rotating shaft. A notch is provided on one side of each limit roller. A support plate is fixed on the rotating shaft below the notch. Conveyor shafts are provided on both sides of the frame. Pulleys are fixed at corresponding positions on the two conveyor shafts. The two pulleys at opposite positions are connected by a conveyor belt. One of the conveyor shafts is fixed to the output end of the conveyor motor.The circuit boards to be processed are stacked between the various positioning devices on the turntable. The circuit boards are positioned and fixed by positioning rods at both ends. The turntable is driven to rotate by a rotary motor. When a positioning device on the turntable reaches its designated position, a cylinder is activated, extending the piston rod and moving a push plate. After the push plate contacts the circuit board at the positioning device, it pushes the circuit board to the angle iron position. The angle iron positions the circuit board, and then the cylinder is activated again, returning the push plate to its initial position. The bottom layer of circuit boards at the angle iron position is blocked on both sides by cam-shaped support plates. The circuit boards are stacked on top of the support plates. A limit motor drives the rotating shaft to rotate. As the rotating shaft rotates, the limit rollers rotate with it. The rubber limit rollers contact the circuit boards at the angle iron positions, squeezing and fixing them. The bottom end of the limit roller contacts the second-to-last circuit board. The rotating shaft continues to rotate, separating the support plate from the bottom layer of circuit boards. The bottom layer of circuit boards falls onto the conveyor belt. A conveyor motor drives the conveyor belt to rotate, moving the bottom layer of circuit boards to a designated position for use by the machine. When further supply is needed... When feeding the circuit board, the limit motor drives the rotating shaft to rotate a certain angle again, and the limit roller rotates with the rotating shaft again. When the notch on the limit roller reaches the position of the circuit board, the circuit board separates from the limit roller, the circuit board at the angle iron position descends, and the bottom layer of circuit boards at the angle iron position is blocked by the support plate again. The cycle continues. After all the circuit boards at the angle iron position have been conveyed to the machine by the conveyor belt, the rotating motor drives the turntable to rotate a certain angle again, pushing the circuit board at the position of the positioning device to the angle iron position again. The cycle continues. This device can divide the circuit board into individual pieces and supply them to the machine. Multiple positioning devices are set on the turntable, and multiple stacked circuit boards are placed on each positioning device. By sequentially conveying the circuit boards at each positioning device position to the angle iron position, they are divided into individual pieces and supplied to the machine. Multiple stacked circuit boards can support the machine for a long period of time. When there are no circuit boards on the turntable, stacked circuit boards are placed at each positioning device position. This device can hold a large number of circuit boards at once, eliminating the need for workers to add circuit boards in a short time.

[0008] Preferably, a gear ring is fixed on the turntable, and a gear is fixed at the output end of the rotary motor, the gear meshing with the gear ring.

[0009] Preferably, air nozzles connected to the air pump are fixed on both sides of the frame of the rotating shaft. When the bottommost circuit board at the angle iron position separates from the support plate, the air pump sprays compressed gas through the air nozzles, and the airflow enters between the two bottommost circuit boards to prevent the bottommost circuit board from adhering to the upper circuit board and failing to fall onto the conveyor belt.

[0010] Compared with existing technologies, the present invention has the following advantages:

[0011] This device can divide circuit boards into individual components and supply them to the machine. Multiple positioning devices are set on the turntable, and multiple stacked circuit boards are placed on each positioning device. By sequentially conveying the circuit boards from each positioning device to the angle iron position, they are divided into individual components and supplied to the machine. Multiple stacked circuit boards can support the machine for a long period of time. When there are no circuit boards on the turntable, stacked circuit boards are placed at each positioning device position. This device can hold a large number of circuit boards at once, eliminating the need for workers to add circuit boards in a short period of time. Attached Figure Description

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0018] Example 1:

[0019] like Figures 1 to 3As shown, this embodiment discloses a feeding device for circuit board processing, including a frame 22. A table 1 is fixed on the frame 22. A turntable 2 is rotatably connected to the table 1 above the table 1. The turntable 2 is driven to rotate by a rotary motor 3. Multiple positioning devices are evenly fixed on the turntable 2. Each positioning device includes multiple positioning rods 5 fixed on the turntable 2. A vertical plate 6 is fixed on the table 1. Multiple cylinders 7 are fixed on the vertical plate 6. A push plate 8 is also provided on one side of the vertical plate 6. The piston rod ends of the cylinders 7 are all fixed to the push plate 8. Angle irons 9 are also fixed on both sides of the frame 22 on one side of the table 1. The frame 22 at the position of the angle irons 9... Each of the two frame 22 has a limit plate 10 fixed on it. The frame 22 between the limit plate 10 and the corresponding angle iron 9 is equipped with a rotating shaft 12. The rotating shaft 12 is driven to rotate by the limit motor 11. The rotating shaft 12 is fixed with a limit roller 13. The limit roller 13 has a notch 14 on one side. The rotating shaft 12 below the notch 14 is fixed with a support plate 15. The frame 22 is equipped with conveyor shafts 16 on both sides. The two conveyor shafts 16 are fixed with pulleys 17 at corresponding positions. The two pulleys 17 at opposite positions are connected by a conveyor belt 19. One of the conveyor shafts 16 is fixed to the output end of the conveyor motor 18.The circuit boards 21 to be processed are stacked between the various positioning devices on the turntable 2. The two ends of the circuit boards 21 are blocked and fixed by the positioning rods 5. The turntable 2 is driven to rotate by the rotary motor 3. When a positioning device on the turntable 2 reaches the designated position, the cylinder 7 is activated, the piston rod on the cylinder 7 is extended, and the push plate 8 moves. After the push plate 8 contacts the circuit board 21 at the positioning device position, it pushes the circuit board 21 to the angle iron 9 position. After the circuit board 21 is positioned by the angle iron 9, the cylinder 7 is activated, and the push plate 8 returns to the initial position. The bottom sides of the bottom of the circuit board 21 at the angle iron 9 position are blocked by the cam-shaped support plates 15. Circuit boards 21 are stacked on top of support plate 15. A limit motor 11 drives a rotating shaft 12 to rotate. As the rotating shaft 12 rotates, a limit roller 13 rotates with it. The rubber limit roller 13 contacts the circuit board 21 at the angle iron 9 position, squeezing and fixing it in place. The bottom end of the limit roller 13 contacts the second-to-last circuit board 21. The rotating shaft 12 continues to rotate, separating the support plate 15 from the bottommost circuit board 21. The bottommost circuit board 21 falls onto the conveyor belt 19. A conveyor motor 18 drives the conveyor belt 19 to rotate, moving the bottommost circuit board 21 to a designated position for supply to the machine. When it is necessary to continue supplying circuit board 21, the limit motor 11 drives the rotating shaft 12 to rotate by a certain angle again. The limit roller 13 rotates with the rotating shaft 12 again. When the notch 14 on the limit roller 13 reaches the position of the circuit board 21, the circuit board 21 separates from the limit roller 13, and the circuit board 21 at the angle iron 9 position descends. The bottom circuit board 21 at the angle iron 9 position is blocked by the support plate 15 again. The cycle continues. After all the circuit boards 21 at the angle iron 9 position have been conveyed to the machine for use by the conveyor belt 19, the rotary motor 3 drives the turntable 2 to rotate by a certain angle again, pushing the circuit board 21 at the position of the positioning device to the angle iron 9 again. This device, operating in a cyclical manner, can divide circuit boards 21 into individual units and supply them to the machine. Multiple positioning devices are installed on the turntable 2, each holding stacked circuit boards 21. The circuit boards 21 at each positioning device are sequentially transported to the angle iron 9 and then divided into individual units for the machine. The stacked circuit boards 21 can support the machine for a considerable period. When there are no circuit boards 21 on the turntable 2, stacked circuit boards 21 are placed at the positioning devices. This device can hold a large number of circuit boards 21 at once, eliminating the need for workers to add circuit boards 21 in a short time.

[0020] Among them, a gear ring is fixed on the turntable 2, and a gear 4 is fixed at the output end of the rotary motor 3, and the gear 4 meshes with the gear ring.

[0021] Example 2:

[0022] This embodiment discloses a feeding device for circuit board processing. Based on the structure and principle of Embodiment 1, this embodiment has air nozzles 20 connected to an air pump fixed on both sides of the frame 22 of the rotating shaft 12. When the bottom circuit board 21 at the angle iron 9 position separates from the support plate 15, the air pump sprays compressed gas through the air nozzles 20, and the airflow enters between the two bottom circuit boards 21, preventing the bottom circuit board 21 from adhering to the upper circuit board 21 and thus preventing it from falling onto the conveyor belt 19.

[0023] 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.
