A PCB board cutting device with an edge and corner burr removal structure

Abstract

This utility model discloses a PCB board cutting device with an edge burr removal structure, belonging to the technical field of PCB board processing. It addresses the problem in existing technologies where uneven stress between the separated portion and the uncut, still-limited portion can lead to PCB board breakage. The device includes a worktable where the PCB board is placed on roller one and transported. An external device drives a cutting component to rotate, which contacts the PCB board and cuts it. The cut PCB board is then transported to roller two and then to roller three. With the assistance of a worker, the cut surface of the PCB board, after being transported by roller three, contacts a grinding component to remove any burrs. This method, to a certain extent, avoids the problem of uneven stress causing PCB board breakage when the uncut portion is still limited after the cut area is separated.

Description

Technical Field

[0001] This utility model belongs to the technical field of PCB board processing, and more specifically, it relates to a PCB board cutting device with a corner burr cleaning structure. Background Technology

[0002] PCB board cutting is an important step in the PCB manufacturing process. It involves cutting large copper-clad laminates into smaller pieces that meet specific size requirements, so that various circuit patterns can be fabricated and processed on these smaller pieces. This process also aims to maximize material utilization and reduce costs.

[0003] The existing announcement number is CN218593083U, which describes a PCB board production cutting machine with an edge and burr removal structure. The machine includes an operating platform horizontally placed on the ground using support legs. Longitudinal mounting brackets are fixedly installed on the front and rear sides of the upper right surface of the operating platform. A PCB board is horizontally placed on the upper surface of the operating platform. A feeding roller is rotatably mounted between the front and rear mounting brackets. A discharging roller is rotatably mounted in the middle position of the upper surface of the operating platform. A cutting blade is rotatably mounted in the middle position of the upper surface of the operating platform. This PCB board production cutting machine with an edge and burr removal structure adopts a novel structural design. After the PCB is cut, the device uses grinding discs on the front and rear sides of the guide block to grind the cut surface, thereby eliminating burrs and avoiding interference with subsequent processing operations. The burr waste is collected in a collection tank through a discharge hole under the action of a negative pressure air pump for easy subsequent processing.

[0004] The aforementioned system uses adjustable bolts to position the limiting plate, achieving precise guidance of the PCB board. A cutting blade then completes the cutting operation. After cutting, the guide block separates the cut PCB board, while grinding discs on both sides of the guide block polish the cut surface, eliminating burrs and improving edge quality. However, when processing longer PCB boards, some cut areas may be guided and separated by the guide block, while uncut areas remain confined by the limiting plate. In this situation, uneven stress can occur between the separated and uncut, confined portions. As cutting continues, this stress accumulates, potentially causing damage to the PCB board. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a PCB board cutting device with an edge and corner burr removal structure. This solves the technical problem in existing technologies where uneven force distribution between the separated portion and the uncut, still-constrained portion generates significant stress. As cutting continues, this stress accumulates, potentially leading to damage to the PCB board.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PCB board cutting device with an edge burr cleaning structure, comprising multiple sets of frames connected to a worktable, some of which are rotatably connected to multiple sets of rollers (first type), some of which are rotatably connected to columns, some of which are rotatably connected to rollers (second type), and some of which are rotatably connected to rollers (third type). Each of the rollers (first type, second type, and third type) has a set of synchronous pulleys connected to one end, and each of the rollers (first type, second type, and third type) has two sets of synchronous pulleys connected to one end. Each pair of synchronous pulleys is connected via a synchronous belt drive. A motor is installed at one end of the frame, and the output end of the motor is connected to a set of rollers. A motor is installed on the worktable, and the output end of the motor is connected to a set of rollers. A motor is installed at one end of the frame, and the output end of the motor is connected to a set of rollers. A double-threaded rod is rotatably connected to a portion of the frame, and the double-threaded rod is threaded to two sets of plates. A double-threaded rod is rotatably connected to a portion of the frame, and the double-threaded rod is threaded to two sets of plates. A grinding assembly is connected to one end of each set of plates. Two cutting assemblies are provided on the outer wall of the column.

[0007] As a preferred technical solution of this utility model, both sets of cutting components are penetrated by sleeves, and multiple sets of holes are opened at one end and the other end of the column. Bolts are threadedly connected to one end and the other end of both sets of sleeves, and the multiple sets of bolts are threadedly connected to the corresponding holes. Both sets of sleeves are movably penetrated by the column.

[0008] As a preferred technical solution of this utility model, each of the two sets of plates is rotatably connected to multiple sets of wheels.

[0009] As a preferred embodiment of this utility model, a rod is connected to a portion of the frame, and the rod is slidably connected to two sets of plates.

[0010] As a preferred technical solution of this utility model, each of the two sets of plate bodies is rotatably connected to a wheel body at one end.

[0011] As a preferred embodiment of this utility model, a second rod is connected to part of the frame, and the second rod is slidably connected to two sets of plates.

[0012] This utility model provides a PCB board cutting device with an edge and corner burr removal structure, which has the following beneficial effects:

[0013] 1. This new type of PCB board is placed on roller 1 by the cooperation of motor 1, motor 2 and motor 3. When motor 1, motor 2 and motor 3 are started, they drive roller 1, roller 2 and roller 3 to rotate synchronously through the cooperation of synchronous pulleys and synchronous belts, thus conveying the PCB board. The cutting component is driven to rotate by an external device. The cutting component contacts the PCB board and cuts it. The cut PCB board is then conveyed to roller 2. When it is conveyed to roller 3, with the assistance of the staff, the cut surface of the PCB board contacts the grinding component after being conveyed by roller 3. This grinds any burrs that may exist on the cut surface, thus avoiding the problem of the uncut area being restricted when the cut area is separated, which may cause the PCB board to break due to uneven force.

[0014] 2. By cooperating with the sleeve, bolts, and cutting components, the bolts are unscrewed from the hole, removing the restriction on the sleeve. The sleeve is then moved, which in turn moves the cutting components. Operators can adjust the position of the cutting components on the column according to actual production needs, thereby achieving customized cutting of PCB boards and cutting them into different sizes, which has a wide range of applicability to a certain extent.

[0023] Please see Figures 1 to 4This utility model provides a technical solution: a PCB board cutting device with an edge burr cleaning structure, including a workbench 1 with multiple sets of frames 2 connected to it, some of the frames 2 being rotatably connected to multiple sets of rollers 3, some of the frames 2 being rotatably connected to columns 4, and the columns 4 being driven to rotate by an external device, thereby driving the cutting assembly 7 to rotate and cut the PCB board, some of the frames 2 being rotatably connected to rollers 5, some of the frames 2 being rotatably connected to rollers 6, and one end of each of the rollers 3, 5, and 6 being connected to a set of synchronous pulleys 9, and some of the rollers 3 and 5 being connected to rollers 6. Two sets of synchronous pulleys 9 are connected to one end of each of the rollers 1, 2, and 3. Each pair of synchronous pulleys 9 is connected by a synchronous belt 10. The synchronous pulleys 9 are installed at one end of each of the rollers 1, 2, and 3, and are driven by the synchronous belts 10. This, in turn, drives the rollers 1, 2, and 3 through motors 1 8, 2 11, and 3 12, ensuring that the rollers 1, 2, and 3 rotate synchronously. This smoothly transports the PCB boards sequentially from roller 1 to roller 2. With the assistance of workers, the polishing assembly 20 then sequentially polishes multiple sections of the PCB boards. The cutting surfaces are in contact. A set of frame 2 has a motor 8 installed at one end; the model of motor 8 can be selected according to actual conditions. The output end of motor 8 is connected to a set of rollers 3. A second motor 11 is installed on the worktable 1; the model of motor 11 can be selected according to actual conditions. The output end of motor 11 is connected to a set of rollers 5. A third motor 12 is installed at one end of a set of frame 2; the model of motor 12 can be selected according to actual conditions. The output end of motor 12 is connected to a set of rollers 6. A double-headed threaded rod is rotatably connected to part of frame 2. 13. Two sets of plates 14 are threadedly connected to a double-headed threaded rod 13. A double-headed threaded rod 27 is rotatably connected to a portion of the frame 2. Two sets of plates 28 are threadedly connected to the double-headed threaded rod 27. A grinding component 20 is connected to one end of each set of plates 28. Two sets of cutting components 7 are provided on the outer wall of the column 4. Rotating the double-headed threaded rod 27 moves the plates 28, which in turn moves the grinding components 20. By adjusting the distance between the two sets of grinding components 20, the cut surfaces of PCBs of different sizes can be ground, making it widely applicable to a certain extent.

[0024] Both sets of cutting components 7 are penetrated by sleeves 22. Multiple sets of holes 23 are opened at one end and the other end of the column 4. Bolts 24 are threaded to one end and the other end of the two sets of sleeves 22. The multiple sets of bolts 24 are threaded to the corresponding holes 23. Both sets of sleeves 22 are movable through the column 4. By unscrewing the bolts 24 out of the holes 23, the restriction on the sleeves 22 is removed. The cutting components 7 can be moved through the sleeves 22, and the position of the cutting components 7 can be adjusted according to actual needs to cut the PCB board into different sizes. It has a wide range of applicability to a certain extent.

[0025] Each of the two sets of plates 14 is rotatably connected to multiple sets of wheels 15 at one end. Rotating the double-headed threaded rod 13 drives the plates 14 to move, and the plates 14 drive the wheels 15 to move. By adjusting the distance between the multiple sets of wheels 15, PCBs of different sizes can be guided and limited.

[0026] Among them, a section of frame 2 is connected to a rod 16, which is slidably connected to two sets of plates 14, and the rod 16 guides the plates 14.

[0027] Both sets of two plates 18 are rotatably connected to wheels 19 at one end. The plates 18 drive the wheels 19 to move, guiding and limiting PCBs of different sizes, so that their contact with the polishing assembly 20 is more stable.

[0028] Among them, a section of frame 2 is connected to a second rod 21, which is slidably connected to two sets of plates 18, and the second rod 21 guides the plates 18.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In use, the PCB board is first placed on roller 3. Rotating the double-threaded rod 13 moves plate 14, which in turn moves wheel 15. By adjusting the spacing between multiple sets of wheel 15, PCB boards of different sizes can be guided and limited. Motors 8, 11, and 12 are then activated. Motor 8 drives roller 3 to rotate, motor 11 drives roller 5 to rotate, and motor 12 causes roller 6 to rotate. Synchronous pulleys 9, connected to one end of rollers 3, 5, and 6, rotate synchronously with the transmission of the synchronous belt 10. This synchronous rotation ensures smooth transport of the PCB board, allowing it to pass through various working areas sequentially. During PCB board transport, an external device drives column 4 to rotate, which in turn drives cutting assembly 7 to cut the PCB board. The cutting assembly 7 is mounted on the column 4 via the sleeve 22. When the cutting position needs to be adjusted, the bolt 24 is unscrewed to release the restriction on the sleeve 22, allowing the sleeve 22 to move and thus move the cutting assembly 7 on the column 4. Operators can flexibly adjust the position of the cutting assembly 7 according to actual production needs to cut the PCB board to the required size, making it quite versatile. The cut PCB board is then conveyed to roller 2 5, and then to roller 3 6. Rotating the double-headed threaded rod 2 17 moves the plate 2 18, adjusting the distance between the two sets of wheels 2 19 and the two sets of grinding assemblies 20. Wheel 2 19 guides and restricts PCB boards of different sizes, making their contact with the grinding assembly 20 more stable. When the PCB board is conveyed to roller 3 6, with the assistance of the operator, the grinding assembly 20 contacts the cutting surfaces of multiple PCB boards in sequence, removing any burrs that may exist on the cutting surfaces, thus improving the edge quality of the PCB board to a certain extent.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
