Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, specifically to an automated bending machine. Background Technology

[0002] In recent years, the printed circuit board (PCB) industry has been developing rapidly and is applied in many areas. Currently, the PCB manufacturing process generally involves first producing a series of PCBs, then cutting dividing grooves into these PCBs, and finally breaking individual PCBs along these grooves. However, traditional PCB breaking operations typically use manual bending, where workers manually break the PCBs apart. This method results in low production efficiency, high production costs, low yield, and poor product consistency. Furthermore, uneven force applied manually leads to uneven break lines, resulting in burrs and poor quality. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing an automated board bending machine that can automatically feed and bend continuous circuit boards, improving production efficiency, reducing production costs, increasing yield, and improving product consistency. At the same time, the circuit boards are subjected to uniform stress, resulting in neat breaks and less burrs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automated plate bending machine includes a frame. A plate positioning assembly is provided on one side of the frame. The plate positioning assembly has a gap passage for the plate to pass through outwards along the X-axis. A plate conveying mechanism is provided on one side of the gap passage, and a plate flipping assembly is provided on the other side of the gap passage. A plate bending drive mechanism is provided on the frame to control the rotation of the plate flipping assembly relative to the plate positioning assembly. During plate bending, the plate flipping assembly presses against the portion of the plate that extends outside the gap passage, causing that portion to break off. The machine achieves this by assembling a plate positioning assembly, a plate conveying mechanism, and a plate flipping assembly on the frame. The system includes components and a folding plate drive mechanism. A gap passage is provided on the continuous plate positioning component. The continuous plate conveying mechanism and the flipping plate assembly are respectively located on both sides of the gap passage. The continuous plate conveying mechanism transports the continuous plates one by one into the gap passage. The folding plate drive mechanism controls the rotation of the flipping plate assembly. When the flipping plate assembly rotates downwards, it presses against the portion of the continuous plate extending outside the gap passage, causing that portion to break off. This achieves automated feeding and folding of the continuous plates, improving production efficiency, reducing production costs, increasing yield, and improving product consistency. Simultaneously, the continuous plates are subjected to uniform force, resulting in neat breaks with minimal burrs and high quality.

[0006] As a preferred embodiment, the connecting plate positioning assembly includes a lower support plate and an upper stop block disposed above the lower support plate, wherein the gap passage is formed between the lower support plate and the upper stop block, and the height of the gap passage is slightly greater than the thickness of the connecting plate.

[0007] As a preferred embodiment, multiple upper blocks are provided, and the multiple upper blocks are spaced apart along the Y-axis direction, with a clearance groove formed between two adjacent upper blocks.

[0008] As a preferred embodiment, the connecting plate positioning assembly further includes a plurality of pressing devices distributed along the Y-axis direction. The movable joint of the pressing device extends downward and is connected to a pressing head for pressing the connecting plate. The pressing head is located directly above the relief groove.

[0009] As a preferred embodiment, the connecting plate positioning assembly further includes at least two connecting plate positioning structures, which are arranged along the Y-axis. Each connecting plate positioning structure includes a hook, and the end of the hook away from the gap passage along the X-axis has a downwardly extending hook portion.

[0010] As a preferred embodiment, the continuous plate positioning assembly further includes a fixing frame, on which the lower support plate, upper stop block, and pressing device are all mounted.

[0011] As a preferred embodiment, the folding and turning plate assembly includes a folding and turning plate base and a plurality of pressing blocks. The two ends of the folding and turning plate base along the Y-axis direction are rotatably connected to the frame via connecting shafts. The plurality of pressing blocks are spaced apart on the folding and turning plate base along the Y-axis direction, and the plurality of pressing blocks protrude in the direction of the upward stop block.

[0012] As a preferred embodiment, the folding plate driving mechanism includes a drive shaft and a servo motor for controlling the rotation of the drive shaft. The drive shaft is rotatably mounted on the frame, and the drive shaft is connected to a connecting shaft at one end of the folding plate seat.

[0013] As a preferred embodiment, the connecting plate conveying mechanism is a conveyor belt, and a pressure roller is provided above the conveyor belt. During operation, the pressure roller makes rolling contact with the upper surface of the connecting plate.

[0014] As a preferred embodiment, the continuous plate conveying mechanism is provided with a continuous plate trough on the side away from the gap passage, and the frame is provided with a material handling mechanism for transferring the continuous plate from the continuous plate trough to the continuous plate conveying mechanism.

[0015] Compared with existing technologies, this invention has significant advantages and beneficial effects. Specifically, by assembling a continuous plate positioning assembly, a continuous plate conveying mechanism, a flipping plate assembly, and a folding plate driving mechanism on a frame, and by providing a gap passage on the continuous plate positioning assembly, the continuous plate conveying mechanism and the flipping plate assembly are respectively located on both sides of the gap passage. The continuous plate conveying mechanism conveys the continuous plates one by one into the gap passage, and the folding plate driving mechanism controls the rotation of the flipping plate assembly. When the flipping plate assembly rotates downward, it presses against the portion of the continuous plate extending outside the gap passage, causing that portion to break. The separation mechanism enables automated feeding and folding of continuous plates, improving production efficiency, reducing production costs, increasing yield, and improving product consistency. Simultaneously, the continuous plates experience uniform stress, resulting in neat breaks with minimal burrs and high quality. During folding, the flipping plate assembly presses against the continuous plates in an arc-shaped motion, concentrating the force at the dividing groove, making them easier to break and improving efficiency. By setting up a continuous plate trough and a picking mechanism, continuous plates can be pre-stacked into the trough and then individually removed and transferred to the conveyor mechanism, thereby improving production efficiency.

They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] like Figure 1-9 As shown, this invention discloses an automated plate bending machine, including a frame 10. A plate positioning assembly 20 is provided on one side of the frame 10. The plate positioning assembly 20 has a gap passage 21 for the plate 40 to pass outward along the X-axis. A plate conveying mechanism 11 is provided on one side of the gap passage 21 to convey the plate 40 into the gap passage 21. A plate flipping assembly 30 is provided on the other side of the gap passage 21. A plate bending drive mechanism 33 is provided on the frame 10 to control the rotation of the plate flipping assembly 30 relative to the plate positioning assembly 20. When bending the plate, the plate flipping assembly 30 presses against the portion 41 of the plate 40 that passes out of the gap passage 21, causing the portion 41 to break apart.

[0042] The continuous plate conveying mechanism 11 is a conveyor belt, and a pressure roller 12 is provided above the conveyor belt. During operation, the pressure roller 12 rolls in contact with the upper surface of the continuous plate 40. By setting the pressure roller 12, the continuous plate 40 is kept in close contact with the conveyor belt, and the conveying is stable.

[0043] The continuous plate conveying mechanism 11 has a continuous plate material trough 13 on the side away from the gap passage 21. The frame 10 is provided with a material picking mechanism 14 for transferring the continuous plate 40 from the continuous plate material trough 13 to the continuous plate conveying mechanism 11. The material picking mechanism 14 includes a crossbeam 15 and a longitudinal drive module 16 for controlling the longitudinal movement of the crossbeam 15. The longitudinal drive module 16 consists of a belt and a motor for controlling the movement of the belt. The crossbeam 15 is connected to the belt and can move with the belt. The crossbeam 15 is provided with a lifting frame 18 and a lifting drive module for controlling the up and down movement of the lifting frame 18. 17. The driving structure of the lifting drive module 17 is similar to that of the longitudinal drive module 16. The lower end of the lifting frame 18 is provided with multiple suction cups 19. By setting up the continuous plate material groove 13 and the material picking mechanism 14, the continuous plates 40 can be pre-stacked into the continuous plate material groove 13, and then picked up one by one by the material picking mechanism 14 and transferred to the continuous plate conveying mechanism 11, thereby improving production efficiency. The flip plate seat 301 is provided with a feeding conveyor belt 36 and a guide plate 37 for guiding the finished product to the feeding conveyor belt 36. The guide plate 37 extends downward at an incline.

[0044] The connecting plate positioning assembly 20 includes a lower support plate 27 and an upper stop block 22 disposed above the lower support plate 27. The gap passage 21 is formed between the lower support plate 27 and the upper stop block 22. The height of the gap passage 21 is slightly greater than the thickness of the connecting plate 40.

[0045] Multiple upper blocks 22 are provided, and the multiple upper blocks 22 are spaced apart along the Y-axis. A clearance groove 26 is formed between two adjacent upper blocks 22. By providing the clearance groove 26, LEDs, chips or capacitors and other components on the connecting plate 40 can be inserted into the clearance groove 26 when the plate is bent, which has a clearance function and prevents damage to the components.

[0046] The connecting plate positioning assembly 20 also includes three pressing devices 28 distributed along the Y-axis. The movable joint of the pressing device 28 extends downward and is connected to a pressing head 281 for pressing the connecting plate 40. The pressing head 281 is located directly above the relief groove 26. The pressing device 28 is a pressing cylinder. When the plate is folded, the pressing head 281 presses against the upper surface of the connecting plate 40 to keep the connecting plate 40 stable.

[0047] The connecting plate positioning assembly 20 also includes at least two connecting plate positioning structures 23. The connecting plate positioning structures 23 are used to position the length of the connecting plate 40 extending out of the gap passage 21. Specifically, there are two connecting plate positioning structures 23, which are arranged along the Y-axis. Each connecting plate positioning structure 23 includes a hook 24. The end of the hook 24 away from the gap passage 21 along the X-axis has a downwardly extending hook portion 25. When folding the plate, the portion 41 of the connecting plate 40 extending out of the gap passage 21 abuts against the lower side wall of the hook portion 25, stopping the connecting plate 40 from extending outward. By setting the connecting plate positioning structure 23, the length of the connecting plate 40 extending out of the gap passage 21 can be positioned, so that the folding position remains consistent each time, improving the folding accuracy.

[0048] The other end of the hook 24 is provided with a connecting hole (not shown). The upper stop block 22 corresponding to the hook 24 is provided with a mounting hole 221 extending along the X-axis direction. The screw passes through the mounting hole 221 and engages with the connecting hole so that the hook 24 can be adjusted and installed on the upper stop block 22 along the X-axis direction. By setting the mounting hole 221 extending along the X-axis direction, the installation position of the hook 24 can be adjusted according to the width of a single plate, thereby improving the positioning accuracy of the connecting plate 40, and thus making the bending accuracy higher, the effect better, and the yield rate higher.

[0049] The connecting plate positioning assembly 20 also includes a fixing frame 201. The lower support plate 27, the upper stop block 22, and the pressing device 28 are all mounted on the fixing frame 201. The fixing frame 201 has a mounting groove 202 extending along the Y-axis. The upper stop block 22 has a connecting groove 222 corresponding to the mounting groove 202. The upper stop block 22 can be horizontally adjusted and mounted on the folding plate fixing seat by screws passing through the connecting groove 222 and cooperating with the nut in the mounting groove 202. By setting the horizontally adjustable upper stop block 22, the width of the clearance groove 26 can be adjusted according to the component size on different connecting plates 40, which has good versatility. The connecting groove 222 extends vertically. By setting the vertically extending connecting groove 222, the upper stop block 22 can also be vertically adjusted and mounted, thereby adjusting the height of the gap passage 21, improving the folding plate accuracy, and adapting to connecting plates 40 of different thicknesses.

[0050] The folding and turning plate assembly 30 includes a folding and turning plate base 301 and a plurality of pressing blocks 31. The two ends of the folding and turning plate base 301 along the Y-axis direction are rotatably connected to the frame 10 through a connecting shaft 32. The plurality of pressing blocks 31 are spaced along the Y-axis direction on the folding and turning plate base 301, and the plurality of pressing blocks 31 protrude toward the upper stop block 22. Specifically, the plurality of pressing blocks 31 correspond one-to-one with the upper stop block 22. The pressing block 31 opposite to the hook 24 is provided with a clearance notch (not shown). The clearance notch penetrates the upper and lower surfaces and side surfaces of the pressing block 31. The clearance notch allows the hook 24 to move up and down. When the pressing block 31 is flipped, the hook 24 can move within the clearance notch, thereby avoiding interference and collision between the hook 24 and the pressing block 31. By setting a plurality of pressing blocks 31 arranged along the Y-axis direction, the connecting plate 40 is subjected to uniform force and the folding effect is good.

[0051] The center line of the connecting shaft 32 is aligned with the side edge of the pressing block 31 facing the upper stop block 22. By setting the center line of the connecting shaft 32 to be aligned with the side edge of the pressing block 31 facing the upper stop block 22, the pressing block 31 can break the connecting plate 40 with the smallest rotation radius, which is highly efficient and makes the structure more compact and occupies less space.

[0052] It should be noted that the pressing block 31 can also be adjusted and installed on the flip plate seat 301 along the Y-axis direction, and its installation method is the same as that of the upper stop block 22.

[0053] The folding plate drive mechanism 33 includes a drive shaft 34 and a servo motor 35 for controlling the rotation of the drive shaft 34. The drive shaft 34 is rotatably mounted on the frame 10, and the drive shaft 34 is connected to the connecting shaft 32 at one end of the flipping folding plate seat 301.

[0054] It should also be noted that the present invention is applicable to bending circuit boards, as well as to bending wooden boards or other plate-like structures, and is not limited to the field of circuit boards.

[0055] The working principle of this invention is as follows: The continuous plates 40 are stacked sequentially in the continuous plate material trough 13. The material taking mechanism 14 takes out the continuous plates 40 from the continuous plate material trough 13 and places them on the conveyor belt. The conveyor belt transports the continuous plates 40 to the gap passage 21. The continuous plates 40 continue to move in the gap passage 21. When the part 41 of the continuous plates 40 extending out of the gap passage 21 abuts against the lower end side wall of the hook part 25, the movement stops. The pressing device 28 controls the pressing head 281 to move downward and press the upper surface of the continuous plates 40. The servo motor 35 controls the transmission shaft 34 to drive the flip plate seat 301 to flip downward. The lower surface of the pressing block 31 presses against the part 41 of the continuous plates 40 extending out of the gap passage 21 and causes the part 41 to break apart and finally fall to the unloading conveyor belt 36.

[0056] In summary, this invention automates the feeding of continuous plates by assembling a plate positioning assembly, a plate conveying mechanism, a tilting plate assembly, and a folding plate driving mechanism on a frame. The plate positioning assembly has a gap passage. The plate conveying mechanism and the tilting plate assembly are respectively located on both sides of the gap passage. The plate conveying mechanism transports the continuous plates one by one into the gap passage. The folding plate driving mechanism controls the tilting plate assembly to rotate. When the tilting plate assembly rotates downwards, it presses against the portion of the continuous plate extending outside the gap passage, causing that portion to separate. Folding plates improve production efficiency, reduce production costs, increase yield, and improve product consistency. Simultaneously, the continuous plates experience uniform stress, resulting in neat breaks with minimal burrs and high quality. By incorporating a flipping plate assembly, the assembly presses against the continuous plates in an arc-shaped motion during folding, concentrating the force on the plates at the dividing grooves, making them easier to break and improving efficiency. Furthermore, by setting up a continuous plate trough and a material handling mechanism, continuous plates can be pre-stacked into the trough and then individually removed and transferred to the conveyor mechanism, thereby improving production efficiency.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technology of the present invention shall still fall within the scope of the technical solution of the present invention.
