Description

Technical Field

[0001] The present invention belongs to the technical field of cutting processing, and particularly relates to a plate cutting device and a cutting method thereof. Background Art

[0002] The cutting or trimming of PCBs is usually carried out by mechanical cutting, which is a relatively common, fast and efficient method. First, after the production of the PCB is completed, the board is cut into the required size and shape by a cutting machine. Currently, the two commonly used board cutting methods on the market are V-knife cutting and digital cutting. V-knife cutting refers to using a V-shaped blade for cutting, which is more suitable for cutting thicker PCB boards, such as aluminum substrate, steel substrate, etc. The advantage of using V-knife cutting is that it is faster, suitable for medium and small batch production, and has a certain adaptability to general PCB boards. Digital cutting refers to using a numerically controlled cutting machine for cutting, which is widely used in fine circuit boards and high-precision PCB boards, such as rigid boards, thin film boards, etc. Since digital cutting has the advantages of high precision and high speed, it is suitable for small batch and rapid production.

[0003] For example, a Chinese patent application for invention with a publication number of CN116038818A discloses a PCB board cutting device, including a processing body; a plurality of rotating rollers are rotatably connected inside the processing body; a feeding belt is installed outside the rotating rollers; a baffle is slidably connected inside the processing body; a spring is fixedly connected between the baffle and the side wall of the processing body; the rotation of the feeding belt is driven by a servo motor; the baffle is arranged at the end position of the feeding belt; a pushing plate is slidably connected inside the processing body; through the structure design of blocking the PCB board by the baffle, then driving the electric push rod to push the pushing plate to descend, and cutting the PCB board with the cutting knife at the bottom of the pushing plate, the function of more conveniently and quickly processing the PCB board is realized, and effectively solves the problem in the prior art that only a single PCB board can be cut and processed, resulting in a low processing efficiency of the PCB board.

[0004] For another example, a Chinese invention patent application with a publication number of CN119057852A discloses a sheet cutting machine, including: a machine body; a step-by-step cutting mechanism for performing the cutting operation in segments to release the stress generated during the cutting process. The step-by-step cutting mechanism includes a lifting plate disposed above the machine body and displaced in the vertical direction. A support plate is provided below the lifting plate. Two telescopic rods are provided between the support plate and the lifting plate. The bottom end of the support plate is slidably connected to a cutting plate. A driving component is provided between the lifting plate and the support plate. By providing the step-by-step cutting mechanism, when cutting the sheet, the cutting plate first displaces downward with the lifting plate as a reference point. Subsequently, the lifting plate serving as the reference point can displace downward under the action of the ratchet block and the ratchet plate to perform step-by-step cutting on the sheet, gradually increasing the cutting depth. This allows the sheet and the cutting plate to have time to release the stress after each cut, thereby reducing the concentration of internal stress.

[0005] Existing cutting devices are difficult to cut multiple plate members at one time. Even when the device cuts multiple plate members at one time, the stress on the plate members is concentrated, which easily affects the cutting quality and the plate members are prone to cracks. Summary of the Invention

[0006] In view of the above problems in the prior art, the purpose of the present invention is to provide a plate member cutting device and its cutting method to solve the problem of avoiding stress concentration during the cutting of multiple plate members by the device.

The left push plate and the right push plate are respectively located on both sides of the side cutting wheel.

[0011] As a further technical solution, the processing table is fixedly installed on the base. A groove is formed on the processing table. Lifting cylinders are evenly installed on the base. A pushing block is installed at the top of the lifting cylinder. The pushing block is located in the groove. An L-shaped groove is correspondingly formed on the pushing block. The plate member is placed in the L-shaped groove. A loading and unloading module is also installed on the base. The loading and unloading module includes a loading end and an unloading end. The loading and unloading module runs through between two longitudinally installed lifting cylinders.

[0012] As a further technical solution, a telescopic cylinder is installed at the bottom end of the processing table. A round rod is installed on the telescopic rod of the telescopic cylinder. A top block is installed on the round rod. The top block is slidably connected to the top of the processing table. A square groove is formed on the base. The square groove is located on one side of the top block.

[0013] As a further technical solution, marks and scale indicators are provided on the processing table. The mark is located at the middle position of the processing table. The scale indicators are distributed on both sides of the mark. A sliding block is slidably connected to the processing table. An auxiliary baffle is connected to the sliding block. The auxiliary baffle is located in the groove and between the plate member and the processing table. A pressing plate is movably installed on the inner side of the auxiliary baffle.

[0014] As a further technical solution, gravity frames are symmetrically installed at the front end of the auxiliary baffle. Counterweight wheels are evenly installed on the gravity frames. Balance ropes are wound around the counterweight wheels. One end of each balance rope is wound around the sliding block.

[0015] As a further technical solution, upper rotating wheels are installed at both ends of the auxiliary baffle. Spring coils are wound around the upper rotating wheels. One of the spring coils is connected to the pressing plate. An installation frame is installed on the sliding block. A lower rotating wheel is installed on the installation frame.

The transmission wheel and the lower rotating wheel are coaxial. A motor is installed on the sliding block. A screw rod is installed on the motor. A rack is threadedly connected to the screw rod. The rack meshes with the lower rotating wheel.

[0016] As a further technical solution, the cutting module is installed on the base. A vertical groove is provided on the base. A vertical plate is installed in the vertical groove. A connecting groove is installed in the vertical plate. A vertical threaded rod is installed in the connecting groove. A vertical motor is installed at the top of the base.

A horizontal plate is installed in the cross beam. A horizontal groove is provided on the horizontal plate. A horizontal threaded rod is rotatably connected in the horizontal groove. The horizontal threaded rod is connected to the horizontal motor. A cutting seat is installed on the horizontal threaded rod.

[0017] A cutting method for a plate cutting device includes the following steps:

[0018] Step 1: The plate is conveyed from the loading end to the unloading end of the loading and unloading module. When the plate is conveyed between the pushing blocks, the pushing blocks are pushed upward by the lifting cylinder to send the plate to the groove. The telescopic cylinder pulls the pushing block inward. After the inner side of the pushing block clamps the plate, the lifting cylinder pulls the pushing block downward again to pick up the plate. The above actions are repeated in sequence to complete multiple pickups of the plate.

[0019] Step 2: The sliding block moves to the accurate position on the processing table. The motor drives the screw to rotate, causing the rack to move. At this time, the transmission wheel rotates and drives the lower runner to rotate together. When the lower runner rotates clockwise, the coil spring is wound up, and the upper runner releases the coil spring, causing the pressing plate to move downward.

[0020] Step 3: The cutting seat moves in the Z direction. The vertical motor drives the vertical threaded rod inside the vertical plate to rotate, and the cross beam moves up and down along the vertical groove, driving the up and down movement of the cutting seat. The cutting seat moves in the X direction. The horizontal motor drives the horizontal threaded rod in the horizontal plate to rotate, and the cutting seat moves linearly along the horizontal groove.

[0021] Step 4: During cutting, the side cutting wheel and the cutting wheel rotate together to cut the plate.

[0022] Step 5: When the plate cutting is completed, the lower runner releases the coil spring counterclockwise, and the upper runner winds up the coil spring, causing the pressing plate to move upward. The lifting cylinder pulls the pushing block downward, causing the plate to continue to be discharged to the unloading end through the loading and unloading module. At the same time, the loading end continues to load, realizing a reciprocating action.

[0023] The beneficial effects of the present invention are:

[0024] The loading and unloading module adopts a crawler transmission structure. The purpose of using crawler transmission is to upload multiple plates at one time, and the action is reliable.

[0025] The cutting seat is provided with a cutting wheel at a fixed position and two movable side cutting wheels. Adjusting the thickness at the cutting position can effectively reduce the cutting stress during single cutting and effectively avoid cracks at the cutting position of the plate.

[0026] A sliding block is slidably connected to the processing table, and an auxiliary material baffle is connected to the sliding block. A pressing plate is movably installed inside the auxiliary material baffle. In order to ensure reliable clamping of multiple plates, the sliding block is movably installed, so that when cutting, the plates are subjected to relatively uniform cutting forces.

[0038] As Figure 1 shown, the present invention provides a plate cutting device, which includes a processing module 2 and a cutting module 3. The processing module 2 includes a processing table 4, on which a plate is carried. The cutting module 3 includes a cutting seat 13, so that after the processing table 4 carries and fixes the plate, the plate is cut by the cutting module 3.

[0039] As Figure 1 and Figure 2 shown, the processing table 4 is fixedly installed on the base 8. A groove 11 is opened on the processing table 4. Lifting cylinders 7 are uniformly installed on the base 8. A pushing block 9 is installed at the top of the lifting cylinder 7. The pushing block 9 is located in the groove 11. An L-shaped groove 10 is correspondingly opened on the pushing block 9. The plate is placed in the L-shaped groove 10. During work, the plate is placed in the L-shaped groove 10, and the groove walls of the L-shaped grooves 10 of the 4 pushing blocks 9 cooperate to limit the plate. The lifting cylinder 7 pushes the plate up to the upper processing position for the cutting module 3 to cut. A loading and unloading module 6 is also installed on the base 8. The loading and unloading module 6 includes a loading end 5 and a discharge end 1. The loading and unloading module 6 runs through and is installed between two longitudinally installed lifting cylinders 7. Preferably, the loading and unloading module 6 adopts a track drive structure. The plate is conveyed from the loading end 5 to the discharge end 1. When the plate is conveyed between the pushing blocks 9, the lifting cylinder 7 pushes the pushing block 9 upwards. After the plate is cut, the lifting cylinder 7 pulls the pushing block 9 downwards, so that the plate continues to be discharged to the discharge end 1 through the loading and unloading module 6, and at the same time, the loading end 5 continues to load, realizing a reciprocating action. The purpose of using track conveyance is that multiple plates can be uploaded at one time, and the action is reliable.

[0040] As Figure 1 andFigure 3 As shown, the cutting module 3 is installed on the base 8. A vertical groove 16 is formed in the base 8. A vertical plate 14 is installed in the vertical groove 16. A connecting groove 20 is installed in the vertical plate 14. A vertical threaded rod is installed in the connecting groove 20. A vertical motor 15 is installed at the top of the base 8. The vertical motor 15 is connected to the vertical threaded rod. A cross beam 18 is installed on the vertical threaded rod. A horizontal motor 17 is installed on one side of the cross beam 18. A horizontal plate 19 is installed in the cross beam 18. A horizontal groove 12 is formed in the horizontal plate 19. A horizontal threaded rod is rotatably connected in the horizontal groove 12. The horizontal threaded rod is connected to the horizontal motor 17. A cutting seat 13 is installed on the horizontal threaded rod. During operation, the vertical motor 15 drives the rotation of the vertical threaded rod inside the vertical plate 14, and the cross beam 18 threadedly connected to the vertical threaded rod moves up and down along the vertical groove 16, thereby driving the up and down movement of the cutting seat 13. The horizontal motor 17 drives the rotation of the horizontal threaded rod inside the horizontal plate 19, so that the cutting seat 13 rotating with the horizontal threaded rod moves linearly along the horizontal groove 12, realizing the movement of the cutting seat 13 in the X direction and the Z direction.

[0041] Embodiment 1

[0042] As Figure 8 and Figure 9 shown, an inner cavity 40 is formed in the cutting seat 13. A whole shaft 52 is rotatably installed in the inner cavity 40. A cutting wheel 51 is installed on the whole shaft 52. The cutting wheel 51 is located above the processing table 4. Side cutting wheels 50 are symmetrically installed on both sides of the cutting wheel 51. The diameter of the side cutting wheel 50 is larger than that of the cutting wheel 51, and there is a gap between the side cutting wheel 50 and the cutting wheel 51. When the lifting cylinder 7 pushes the plate upward to the cutting and processing position, the whole shaft 52 rotates, so that the cutting wheel 51 and the side cutting wheels 50 rotate. Since the diameter of the side cutting wheel 50 is large, it contacts the plate first. After the side cutting wheel 50 cuts a certain margin of the plate first, the cutting wheel 51 then contacts the plate. At this time, the cutting stress during a single cutting can be effectively reduced, and cracks at the cutting position of the plate can be effectively avoided.

[0043] Further, in order to adjust the thickness at the cutting position, a driving part is also installed in the inner cavity 40. The driving part is located at the top end of the inner cavity 40 and is connected to the side cutting wheel 50. The entire shaft 52 includes a secondary rotating shaft 46 and a main rotating shaft 49. One end of the secondary rotating shaft 46 is fixedly connected to the inner cavity 40, and the other end is rotatably installed with a small-end rotating shaft 47. Both ends of the main rotating shaft 49 are fixedly installed with fixing parts 48, and the fixing parts 48 are clamped with the small-end rotating shaft 47. The cutting wheel 51 is sleeved on the main rotating shaft 49, and the side cutting wheel 50 is sleeved on the main rotating shaft 49 and the secondary rotating shaft 46. The operation of the side cutting wheel 50 is controlled by the driving part. That is, when the driving part makes the side cutting wheel 50 contact with the secondary rotating shaft 46 and the main rotating shaft 49, at this time, the rotation speed of the cutting wheel 51 is higher than that of the side cutting wheel 50, making the cut surface smooth. At the same time, the purpose of dispersing the cutting stress is better achieved.

[0044] As Figure 8 shown, the driving part includes a left push plate 44 and a right push plate 45. A steel plate is welded between the left push plate 44 and the right push plate 45. A vertical plate 42 is installed at the top end of the inner cavity 40. Main push cylinders 43 are installed on both sides of the vertical plate 42. The other end of the main push cylinder 43 is connected to the left push plate 44. A slide rail 41 is also installed at the top end of the inner cavity 40. The steel plate is slidably connected to the slide rail 41. The main push cylinder 43 drives the steel plate to move on the slide rail 41. The left push plate 44 and the right push plate 45 are respectively located on both sides of the side cutting wheel 50. Therefore, during the movement of the steel plate, the left push plate 44 or the right push plate 45 respectively contacts the side cutting wheel 50.

[0045] Specifically, when the thickness at the cutting position needs to be thin, the main push cylinder 43 pulls the steel plate towards the middle. At this time, the right push plate 45 contacts the side cutting wheel 50 and moves the side cutting wheel 50 onto the main rotating shaft 49. Both the side cutting wheel 50 and the cutting wheel 51 are on the main rotating shaft 49. The side cutting wheel 50 first contacts the plate member and cuts two notches at the cutting position. Then, the cutting wheel 51 cuts the plate member, reducing the stress when the cutting wheel 51 contacts the plate member. On the contrary, when there is no requirement for the thickness at the cutting position and in order to improve the flatness of the cut surface, the main push cylinder 43 pushes the steel plate towards both ends. At this time, the left push plate 44 contacts the side cutting wheel 50, making the side cutting wheel 50 respectively contact the secondary rotating shaft 46 and the main rotating shaft 49. At this time, the rotation speed of the side cutting wheel 50 is reduced, and through the cooperation of the side cutting wheel 50 and the cutting wheel 51, the cutting action is completed.

[0046] Embodiment 2

[0047] Based on the above Embodiment 1, in addition to stacking the plate members together during feeding, in order to be able to cut multiple plate members at one time, as Figure 1 , Figure 4 and Figure 5As shown in the figure, a telescopic cylinder 22 is installed at the bottom end of the processing table 4. A round rod 23 is installed on the telescopic rod of the telescopic cylinder 22. A material pushing block 24 is installed on the round rod 23. The material pushing block 24 is slidably connected to the top end of the processing table 4. A square groove 21 is formed in the base 8. The square groove 21 is located on one side of the material pushing block 24 to facilitate the movement of the material pushing block 24.

[0048] During specific operation, the loading and unloading module 6 sequentially conveys single sheet workpieces. The lifting cylinder 7 pushes up the material pushing block 9 to send the workpiece to the groove 11. The telescopic cylinder 22 pulls the material pushing block 24 inward. After the inner side of the material pushing block 24 clamps the workpiece, the lifting cylinder 7 then pulls down the material pushing block 9 to pick up the workpiece again, continues to push up the workpiece to the lower part of the first workpiece, releases the material pushing block 24. After both workpieces are located between the material pushing blocks 24, the material pushing blocks 24 clamp again. By repeating the above actions in sequence, the purpose of simultaneously cutting and processing multiple workpieces can be achieved.

[0049] Embodiment 3

[0050] On the basis of the above Embodiment 2, in order to ensure reliable clamping of multiple workpieces, as Figure 6 and Figure 7 shown in the figure, a sliding block 26 is slidably connected to the processing table 4. An auxiliary material retaining plate 30 is connected to the sliding block 26. The auxiliary material retaining plate 30 is located in the groove 11 and between the workpiece and the processing table 4. A pressing plate 28 is movably installed on the inner side of the auxiliary material retaining plate 30. The sliding block 26 is pushed to move on the processing table 4 by a cylinder (not shown). The position of the workpiece is indicated from top to bottom by the pressing plate 28. And there are marks 27 and scale indicators 25 on the processing table 4. The mark 27 is located at the middle position of the processing table 4. The scale indicators 25 are distributed on both sides of the mark 27. According to the size of the workpiece, the position of the sliding block 26, that is, the contact position between the pressing plate 28 and the workpiece, is accurately moved, so that when cutting, the workpiece receives a relatively uniform cutting force.

[0051] Furthermore, in order to ensure the stability of the auxiliary material retaining plate 30, gravity frames 32 are symmetrically installed at the front end of the auxiliary material retaining plate 30. Counterweight wheels 31 are uniformly installed on the gravity frames 32. Balance ropes 39 are wound around the counterweight wheels 31. One end of each balance rope 39 is wound on the sliding block 26, and the auxiliary material retaining plate 30 is stably installed on the sliding block 26, so that the auxiliary material retaining plate 30 moves together with the sliding block 26.

[0052] Further, in order to adjust the vertical position of the pressure plate 28, upper runners 29 are installed at both ends of the auxiliary stop plate 30. Coil springs are wound around the upper runners 29. One of the coil springs is connected to the pressure plate 28. An installation bracket 34 is installed on the sliding block 26. A lower runner 33 is installed on the installation bracket 34. One end of the other coil spring is wound around the lower runner 33. A transmission wheel 35 is also installed on the installation bracket 34. The transmission wheel 35 and the lower runner 33 are coaxial. A motor 38 is installed on the sliding block 26. A screw rod 37 is installed on the motor 38. A rack 36 is threadedly connected to the screw rod 37. The rack 36 meshes with the lower runner 33. When adjusting the position of the pressure plate 28, the motor 38 drives the screw rod 37 to rotate, causing the rack 36 to move. At this time, the transmission wheel 35 rotates and drives the lower runner 33 to rotate together. When the lower runner 33 rotates clockwise, the coil spring is wound up, and the upper runner 29 releases the coil spring, causing the pressure plate 28 to move downward. Conversely, when the lower runner 33 rotates counterclockwise, the coil spring is released, and the upper runner 29 winds up the coil spring, causing the pressure plate 28 to move upward, so as to fix the plate member with the pressure plate 28 and prevent the instability of multiple plate members during cutting.

[0053] The working principle of the present invention: The plate member is conveyed from the loading end 5 of the loading and unloading module 6 to the unloading end 1. When the plate member is conveyed between the pushing blocks 9, the pushing blocks 9 are pushed upward by the lifting cylinder 7, and the plate member is sent to the groove 11. The telescopic cylinder 22 pulls the ejector block 24 inward. After the inner side of the ejector block 24 clamps the plate member, the lifting cylinder 7 pulls the pushing blocks 9 downward again to pick up the plate member. The above actions are repeated in sequence to complete multiple pick-ups of the plate member. The sliding block 26 moves to the accurate position on the processing table 4. The motor 38 drives the screw rod 37 to rotate, causing the rack 36 to move. At this time, the transmission wheel 35 rotates and drives the lower runner 33 to rotate together. When the lower runner 33 rotates clockwise, the coil spring is wound up, and the upper runner 29 releases the coil spring, causing the pressure plate 28 to move downward. The cutting seat 13 moves in the Z direction. The vertical motor 15 drives the vertical threaded rod inside the vertical plate 14 to rotate, and the cross beam 18 moves up and down along the vertical groove 16, driving the up and down movement of the cutting seat 13. The cutting seat 13 moves in the X direction. The horizontal motor 17 drives the horizontal threaded rod in the horizontal plate 19 to rotate, and the cutting seat 13 moves linearly along the horizontal groove 12. During cutting, the side cutting wheel 50 and the cutting wheel 51 rotate together to cut the plate member. After the plate member is cut, when the lower runner 33 rotates counterclockwise, the coil spring is released, and the upper runner 29 winds up the coil spring, causing the pressure plate 28 to move upward. The lifting cylinder 7 pulls the pushing blocks 9 downward, causing the plate member to continue to discharge through the loading and unloading module 6 to the unloading end 1. At the same time, the loading end 5 continues to load, realizing the reciprocating action.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
