Description

Technical Field

[0001] This invention relates to the field of electronic component cutting technology, and more specifically, to a cutting apparatus for processing electronic components. Background Technology

[0002] In the field of electronic component processing, circuit boards, as the core carrier for electrical connections of electronic components, directly determine the operational stability and service life of electronic equipment through their processing accuracy. The cutting process is a key step in the circuit board processing, which requires cutting the initially produced whole board into smaller boards of appropriate sizes according to actual application needs, laying the foundation for subsequent assembly processes. Currently, among the circuit board cutting methods commonly used in the industry, limit positioning is the core prerequisite for ensuring cutting accuracy. Usually, workers need to manually place the circuit board on the limit table of the cutting device, and the limit mechanism on the limit table clamps and fixes the circuit board to ensure that the circuit board does not shift during the cutting process, thereby ensuring that the cutting path is consistent with the preset trajectory. However, when workers manually place circuit boards, factors such as operational negligence and visual deviation can easily lead to improper placement, resulting in problems such as offset or tilt. In this case, the limiting mechanism on the limiting platform can only effectively limit the part of the circuit board that is in place, while the area that is not in place cannot be fully constrained and is in an unlimited state. This incomplete limiting state will directly affect the cutting effect. During the cutting process, the unlimited area is prone to slight displacement. Even a small displacement will cause the cutting position to deviate from the preset trajectory, resulting in defects such as cutting size deviation, edge burrs, and cracks. In severe cases, it may even damage the electronic components on the circuit board and reduce the product qualification rate. Summary of the Invention

[0003] The purpose of this invention is to provide a cutting apparatus for processing electronic components, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A cutting device for processing electronic components includes a base plate, a support frame fixedly mounted on the upper surface of the base plate, a rotating disk rotatably mounted on the upper surface of the support frame, a plurality of limiting frames placed circumferentially on the upper end of the rotating disk, each limiting frame having a limiting groove and a limiting block fixedly mounted within the limiting groove, and a disassembly assembly for limiting the plurality of limiting frames on the upper surface of the rotating disk; a rotating assembly for driving the rotating disk to rotate on the lower surface of the support frame; a mounting plate above the base plate, with opposing mounting frames bent at both ends fixedly mounted on the upper surface of the mounting plate, and a moving assembly for driving the two mounting frames to reciprocate.

[0008] Preferably, a first rack is fixedly installed on the upper side of the lower end of the mounting bracket; The moving assembly includes two bases fixedly mounted on the upper surface of the base plate, a base rod rotatably mounted between the two bases, and two first gears fixedly mounted on the outer side wall of the base rod and meshing with two first racks.

[0009] Preferably, opposing push frames are fixedly installed on the upper end face of the base plate, opposing push shafts are fixedly installed between the two push frames, a slide plate is slidably sleeved between the two push shafts, opposing slide rods that penetrate the push plate are fixedly installed on the side wall of the slide plate facing the push plate, a slide ring is fixedly installed at the penetrating end of the slide rod, and a first spring is sleeved on the slide rod located between the push plate and the push frame.

[0010] Preferably, the support frame is fixedly mounted with opposing and bent fixing frames on the side wall facing the mounting frame. Opposing fixing cylinders are fixedly mounted on the lower end face of the fixing frames. A fixing cavity is opened inside the fixing cylinder. A fixing ring is fixedly mounted at the opening of the fixing cavity. A fixing block is placed inside the fixing cavity. A fixing rod is fixedly mounted on the side wall facing the fixing ring, with its lower end passing through the fixing ring and fixedly connected to the upper end face of the lifting plate. A second spring is sleeved on the fixing rod inside the fixing cavity to push the fixing block away from the fixing ring.

[0011] Preferably, a pressing plate is fixedly installed on the side wall of the lifting plate facing the mounting frame, a pressing block is fixedly installed on the upper end face of the pressing plate, and a pressing slope is opened at the end of the pressing block facing the mounting frame; The limiting assembly includes two mounting rods fixedly installed on the lower end face of the mounting plate. A mounting block is fixedly installed on the lower end face of the mounting rods, and the side wall of the mounting block is provided with a mounting slope that matches the pressing slope.

[0012] Preferably, a rotating cylinder with its lower end penetrating the support frame is fixedly installed on the lower end face of the rotating disk, and a second gear is fixedly sleeved on the penetrating end of the rotating cylinder; The rotating assembly includes two support seats fixedly mounted on the lower end face of the support frame. A second electric push rod is fixedly mounted between the two support seats. A connecting block is fixedly mounted on the output shaft of the second electric push rod. A second rack that meshes with the second gear is fixedly mounted on the upper end face of the connecting block.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by driving the pusher plate, pusher rod and pusher block to move, ensures that one end of the circuit board is tightly abutted against the limit block in the limit frame. At the same time, the size of the limit groove is adapted to the circuit board, so that each side wall of the circuit board fits against the side wall of the limit groove. With the help of the limit component driving the lifting plate to move the rubber block to press against the circuit board, the circuit board is completely limited throughout the process, effectively avoiding the displacement of the circuit board during the cutting process, reducing cutting defects, avoiding damage to the electronic components on the circuit board, and significantly improving the product qualification rate.

[0014] 2. In this invention, a rotating disk is rotatably mounted on the upper surface of the support frame. Multiple limiting frames are placed circumferentially on the upper end of the rotating disk. Each limiting frame has a limiting groove for placing circuit boards. The rotating disk is driven to rotate at intervals by a rotating component, so that the limiting frames without circuit boards can be moved to a position away from the mounting frame in sequence, which makes it convenient for the staff to continuously put in the circuit boards to be cut. At the same time, the limiting frames with circuit boards can be moved to the bottom of the mounting plate in sequence for cutting. After cutting, the disk rotates to the material picking position, realizing a continuous cycle of material feeding, cutting and picking. There is no need to wait for a single cutting to be completed before feeding, which greatly shortens the processing interval and improves the overall processing efficiency.

[0015] 3. In this invention, when it is necessary to cut circuit boards of different sizes, the operator can release the limit frame by using the disassembly and assembly component, replace it with a limit frame that matches the size of the circuit board to be cut, and then use the disassembly and assembly component to simultaneously limit multiple limit frames, thus completing the quick replacement of the limit frame. The disassembly and assembly component drives the lifting plate and lifting rod to rise and fall through the lifting component, realizing the quick fixing and unlocking of the limit frame. The operation is convenient and requires no additional tools, enabling the device to meet the cutting needs of circuit boards of different specifications, expanding the scope of application, and improving the versatility and practicality of the device.

[0016] 4. In this invention, a rubber block is fixedly installed on the lower end face of the lifting plate, and the support rod limits the lifting plate to ensure stable lifting. When the limiting component drives the lifting plate to move down, the rubber block abuts against the circuit board. The rubber block has a certain elasticity, which can realize flexible clamping of the circuit board and avoid damage to the surface of the circuit board or electronic components caused by excessive clamping force in traditional rigid limiting mechanisms.

[0017] 5. In this invention, the first spring in the pushing component can be further compressed after the circuit board abuts against the limiting block to form a thrust balance, which can not only ensure the stable clamping of the circuit board, but also avoid damage caused by excessive compression, thus achieving dual protection for the circuit board.

[0018] 6. In this invention, a dust collector is fixedly installed on the upper surface of the base plate, and a suction pipe is fixedly installed on the side wall of the dust collector. One end of the suction pipe passes through the rotating cylinder, rotating disk, and lifting disk, and a suction block is fixedly installed at the through end. During the circuit board cutting process, the cutting component generates a large amount of dust. The dust collector can absorb the dust generated during cutting in real time through the suction pipe and suction block, and collect the dust into the dust collector, preventing the dust from spreading and polluting the processing environment. At the same time, it prevents workers from inhaling dust and harming their health, creating a clean and safe processing environment and reducing environmental cleaning costs.

[0033] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0034] The following is in conjunction with the appendix Figures 1-13 This embodiment will be described in further detail.

[0035] A cutting device for processing electronic components in this embodiment includes a base plate 10. A support frame 11 is fixedly installed on the upper end surface of the base plate 10. A rotating disk 12 is rotatably installed on the upper end surface of the support frame 11. Multiple limiting frames 13 are placed on the upper end of the rotating disk 12 along its circumference. A limiting groove for placing a circuit board is opened in the limiting frame 13. A limiting block 14 for the circuit board to abut is fixedly installed in the limiting groove. A disassembly and assembly assembly for limiting the multiple limiting frames 13 is provided on the upper end surface of the rotating disk 12. The lower end face of the support frame 11 is provided with a rotating assembly for driving the rotating disk 12 to rotate; A mounting plate 15 is provided above the base plate 10. The upper end surface of the mounting plate 15 is fixedly mounted with opposing mounting brackets 16 that are bent at both ends. The upper end surface of the base plate 10 is provided with a moving component for driving the two mounting brackets 16 to move back and forth. The lower end face of the mounting plate 15 is provided with a dividing component, and the mounting plate 15 is moved to drive the dividing component to cut the circuit board. A push plate 17 is provided above the base plate 10. A push rod 18 is fixedly installed on the upper end surface of the push plate 17. A push block 19 is fixedly installed on the bent end of the push rod 18. A push assembly for driving the push plate 17 to move is provided on the upper end surface of the base plate 10. Multiple support rods 20 are fixedly installed on the upper end face of the support frame 11. A lifting plate 21 is slidably sleeved between two support rods 20. A rubber block is fixedly installed on the lower end face of the lifting plate 21. A limiting component is provided on the upper end face of the support frame 11. The mounting plate 15 moves back and forth to drive the limiting component to limit or release the circuit board in the limiting groove.

[0036] In this embodiment, the operator places the circuit board to be cut in the limiting slot away from the mounting bracket 16, ensuring that one end of the circuit board abuts against the limiting block 14. Then, the rotating component drives the rotating disk 12 to rotate intermittently, allowing the limiting bracket 13 without circuit boards to be positioned sequentially away from the mounting bracket 16. As the limiting bracket 13 passes sequentially away from the mounting bracket 16, the operator needs to place the circuit board into the corresponding limiting slot. When the rotating component drives the rotating disk 12 to rotate continuously at intervals, the limiting bracket 13 with circuit boards will move towards the mounting bracket 16. When the limiting bracket 13 with circuit boards moves to below the mounting plate 15, the pushing component drives the pushing plate 17 to move towards the support frame 11. The movement of the pushing plate 17 is achieved by pushing... The lever 18 can drive the push block 19 to move, so that the two push blocks 19 can move the circuit board below the mounting plate 15, ensuring that one end of the circuit board abuts against the limiting block 14. Then, the moving component drives the mounting frame 16 to move towards the support frame 11. The movement of the mounting frame 16 can drive the mounting plate 15 to move towards the support frame 11. When the mounting plate 15 moves towards the support frame 11, the mounting plate 15 can drive the limiting component, so that the lifting plate 21 starts to move down. The downward movement of the lifting plate 21 will drive the rubber block to move down, so that the lower end of the rubber block passes through the limiting frame 13 and abuts against the circuit board, thereby limiting the circuit board to be cut. When the moving component drives the dividing component below the mounting plate 15 to pass through the circuit board after the limiting, the dividing component can cut the circuit board. After the cutting component completes the cutting of the circuit board, the pushing component is driven to move the pushing plate 17 away from the support frame 11, so that the pushing plate 17 can drive the pushing block 19 away from the circuit board through the pushing rod 18. Then, the moving component drives the mounting plate 15 away from the support frame 11, and the mounting frame 16 can drive the mounting plate 15 away from the support frame 11. At this time, the mounting plate 15 will drive the limiting component again, so that the limiting component will drive the lifting plate 21 to move upward. The upward movement of the lifting plate 21 will drive the rubber block to move upward, releasing the rubber block from pressing against the circuit board. After the above steps are completed, the rotating disk 12 is driven to rotate at intervals again. When the cut circuit board rotates to a position away from the mounting frame 16, the operator can take the cut circuit board out of the limiting groove and put it into the circuit board to be cut. The size of the limiting groove is adapted to the size of the circuit board. When the circuit board is placed in the limiting groove, each side wall of the circuit board fits against the side wall of the limiting groove. When one end of the circuit board is pressed against the limiting block 14, the other end of the circuit board is flush with the outer side wall of the limiting frame 13, so that the circuit board can be fully limited in the limiting groove. When it is necessary to cut circuit boards of different sizes, the limiting brackets 13 need to be released by the disassembly and assembly components, so that the workers can replace the limiting brackets 13 on the rotating disk 12 to adapt to the circuit boards of different sizes. After the limiting brackets 13 are replaced, the multiple limiting brackets 13 on the rotating disk 12 are simultaneously limited by the disassembly and assembly components, so that the limiting brackets 13 can be replaced on the rotating disk 12. Among them, the lifting plate 21 is limited by the support rod 20, so that the lifting plate 21 can only move up and down stably along the support rod 20. When the lifting plate 21 is pressed against the rubber block, it can protect the circuit board to a certain extent and avoid hard pressing, which would cause damage to the circuit board. In this device, by driving the two push blocks 19 to push one end of the circuit board against the limiting block 14, the circuit board can be placed in the limiting groove. Compared with the existing devices, this type of cutting device for electronic component processing can ensure that the circuit board is in a fully limited state throughout the entire process, effectively avoiding the impact of circuit board displacement on the cutting effect, ensuring cutting accuracy, reducing cutting defects, and improving product qualification rate. The mounting plate 15 has a fixed support 66 on its lower end face, and a second motor 67 is fixedly installed between the two supports 66. The output shaft of the second motor 67 is fixedly installed with a blade 68. The blade 68 is driven to rotate by the second motor 67. When the mounting plate 15 moves toward the support frame 11, the rotating blade 68 can cut the circuit board.

[0037] In this embodiment, a limiting seat 22 is fixedly installed on the opposite side wall of the limiting frame 13, and a plurality of through rods 23 with their upper ends penetrating through the limiting seat 22 are fixedly installed on the upper surface of the rotating disk 12. The assembly includes a lifting plate 24 located on the upper end of the rotating plate 12. Multiple lifting rods 25 are fixedly installed on the outer wall of the lifting plate 24 and sleeved on the through end of the through rod 23. The upper end of the rotating plate 12 is provided with a lifting component for driving the lifting plate 24 to move up and down.

[0038] In this embodiment, the limiting frame 13 is placed on the upper surface of the rotating disk 12, and the limiting seat 22 is sleeved on the corresponding through rod 23 to achieve the pre-installation of the limiting frame 13 on the rotating disk 12. Then, the lifting disk 24 is driven to move down by the lifting component. The downward movement of the lifting disk 24 can drive the lifting rod 25 to move down, and the lifting rod 25 is sleeved on the through end of the through rod 23 to achieve the installation of the limiting frame 13 on the rotating disk 12. The lifting mechanism drives the lifting plate 24 to move upward, which in turn moves the lifting rod 25 upward, causing it to slide out of the through rod 23 and release the restriction on the multiple limit frames 13. At this time, the operator lifts the limit frame 13, causing the limit seat 22 to slide out from the outer wall of the through rod 23, allowing the limit frame 13 on the rotating plate 12 to be replaced.

[0039] In this embodiment, a rotating rod 26 that is opposite to and passes through the lifting plate 24 is fixedly installed on the upper end surface of the rotating plate 12, and a rotating ring 27 is fixedly installed at the through end of the rotating rod 26. The lifting component includes two threaded rods 28 rotatably mounted on the upper end face of the rotating disk 12, with the upper ends of the two threaded rods 28 threaded through the lifting disk 24.

[0040] In this embodiment, two rotating rods 26 limit the lifting plate 24, and the lower end of the threaded rod 28 is rotatably mounted in the upper end face of the rotating plate 12 through a bearing. When the two threaded rods 28 rotate synchronously, the threaded rods 28 can drive the lifting plate 24 to rise and fall along the height direction of the threaded rods 28. The upward movement of the lifting plate 24 is limited by the rotating ring 27 to prevent the lifting plate 24 from moving too high and affecting its actual use. The outer walls of the two threaded rods 28 are fixedly fitted with synchronous pulleys 29, and a synchronous belt 30 is fitted between the two synchronous pulleys 29. When the operator drives one of the threaded rods 28 to rotate, the rotating threaded rod 28 can drive the synchronous pulley 29 to rotate. The rotation of the synchronous pulley 29 can drive the synchronous pulley 29 on the other threaded rod 28 to rotate through the synchronous belt 30, that is, the other threaded rod 28 rotates, so as to realize the synchronous rotation of the two threaded rods 28. Each of the two threaded rods 28 has a handle fixedly installed at its upper end, which allows the operator to easily drive the threaded rods 28 to rotate.

[0041] In this embodiment, a first rack 31 is fixedly installed on the upper side of the lower end of the mounting bracket 16; The moving assembly includes two bases 32 fixedly mounted on the upper end face of the base plate 10, and a base rod 33 rotatably mounted between the two bases 32. Two first gears that mesh with two first racks 31 are fixedly mounted on the outer side wall of the base rod 33.

[0042] In this embodiment, the two ends of the base rod 33 are rotatably mounted in the corresponding base 32 through bearings. When the base rod 33 reciprocates, the base rod 33 can drive the two first racks 31 to reciprocate through the two first gears. The reciprocating movement of the first racks 31 can drive the two mounting brackets 16 to move, that is, the mounting plate 15 to reciprocate. Among them, a first motor 61 is fixedly installed on the side wall of one of the bases 32. The output shaft of the first motor 61 is fixedly connected to the base rod 33, so that the first motor 61 can drive the base rod 33 to reciprocate. The upper end face of the base plate 10 is fixedly installed with a corresponding snap-fit ​​plate 64, and the lower end face of the mounting bracket 16 is fixedly installed with a snap-fit ​​block 65 with a T-shaped cross section. By snapping the snap-fit ​​block 65 into the corresponding snap-fit ​​plate 64, the mounting bracket 16 is slidably installed on the upper end face of the base plate 10, that is, the mounting plate 15 is slidably installed above the base plate 10.

[0043] In this embodiment, opposing push frames 34 are fixedly installed on the upper end face of the base plate 10, opposing push shafts 35 are fixedly installed between the two push frames 34, and a sliding plate 36 is slidably sleeved between the two push shafts 35. Opposing and penetrating slide rods 37 are fixedly installed on the side wall of the slide plate 36 facing the push plate 17. A slip ring 38 is fixedly installed at the penetrating end of the slide rod 37. A first spring 39 is sleeved on the slide rod 37 located between the push plate 17 and the push frame 34. The first spring 39 is used to drive the push plate 17 to move towards the slip ring 38. The pushing assembly includes a first electric push rod 40 fixedly installed on one side wall of the push frame 34, and the output shaft of the first electric push rod 40 is fixedly connected to the slide plate 36.

[0044] In this embodiment, two push shafts 35 pass through the slide plate 36, enabling the slide plate 36 to slide on the upper surface of the base plate 10. The slide rod 37 on the slide plate 36 passes through the push plate 17, enabling the push plate 17 to slide on the base plate 10. At the same time, the slip ring 38 limits the push plate 17 to prevent the push plate 17 from sliding out of the slide rod 37. When the first electric push rod 40 drives the slide plate 36 to move towards the support frame 11, the slide plate 36 can push the push plate 17 to move through the first spring 39. The push plate 17 drives the push block 19 to move through the push rod 18, so that the push block 19 can push the circuit board to abut against the limit block 14. When the circuit board comes into contact with the limiting block 14, the first electric push rod 40 continues to output pushing force, and the first spring 39 will be further compressed. At this time, the reaction force generated by the first spring 39 is balanced with the pushing force of the electric push rod, which can ensure that the circuit board is stably clamped and avoid damage caused by excessive compression, thus playing a dual protection role.

[0045] In this embodiment, a fixed frame 41 with opposite and bent sides is fixedly installed on the side wall of the support frame 11 facing the mounting frame 16. A fixed cylinder 42 with opposite sides is fixedly installed on the lower end face of the fixed frame 41. A fixed cavity is opened in the fixed cylinder 42. A fixed ring 43 is fixedly installed at the opening of the fixed cavity. A fixed block 44 is placed in the fixed cavity. A fixed rod 45 with its lower end passing through the fixed ring 43 and fixedly connected to the upper end face of the lifting plate 21 is fixedly installed on the side wall of the fixed block 44 facing the fixed ring 43. A second spring 46 for pushing the fixed block 44 away from the fixed ring 43 is sleeved on the fixed rod 45 in the fixed cavity.

[0046] In this embodiment, the second spring 46 and the fixing block 44 in the fixing cavity are intercepted by the fixing ring 43, so that the fixing block 44 and the second spring 46 are installed in the fixing cavity. When the second spring 46 pushes the fixing block 44 away from the fixing ring 43, the fixing block 44 can drive the fixing rod 45 to move upward. The upward movement of the fixing rod 45 can drive the lifting plate 21 to move upward, so that the rubber block on the lower end of the lifting plate 21 releases its pressure on the circuit board. The fixed cylinder 42 is mounted above the support frame 11 via the fixed bracket 41; In this embodiment, a pressing plate 47 is fixedly installed on the side wall of the lifting plate 21 facing the mounting frame 16, and a pressing block 48 is fixedly installed on the upper end surface of the pressing plate 47. A pressing slope is opened at one end of the pressing block 48 facing the mounting frame 16. The limiting assembly includes two mounting rods 49 fixedly mounted on the lower end face of the mounting plate 15. A mounting block 50 is fixedly mounted on the lower end face of the mounting rods 49. The side wall of the mounting block 50 is provided with a mounting slope that cooperates with the pressing slope.

[0047] In this embodiment, when the mounting plate 15 moves toward the support frame 11, the mounting plate 15 can drive the mounting rod 49 to move. At this time, the mounting block 50 at the lower end of the mounting rod 49 can squeeze the pressing slope through the mounting slope, so that the mounting block 50 can push the pressing block 48 to move down. The pressing block 48 moving down can drive the pressing plate 47 to move down. The pressing plate 47 moving down can drive the lifting plate 21 to move down. That is, the rubber block below the lifting plate 21 can squeeze the circuit board. The upper end of the base plate 10 is fixedly installed with a vertical cylinder 63, and the lower end of the pressing plate 47 is fixedly installed with a vertical rod 62 inserted into the vertical cylinder 63. The vertical cylinder 63 limits the vertical rod 62, making the lifting and lowering of the pressing plate 47 more stable.

[0048] In this embodiment, a rotating cylinder 51 with its lower end penetrating the support frame 11 is fixedly installed on the lower end face of the rotating disk 12, and a second gear 52 is fixedly sleeved on the penetrating end of the rotating cylinder 51. The rotating assembly includes two support seats 53 fixedly mounted on the lower end face of the support frame 11. A second electric push rod 54 is fixedly mounted between the two support seats 53. A connecting block 55 is fixedly mounted on the output shaft of the second electric push rod 54. A second rack 56 that meshes with the second gear 52 is fixedly mounted on the upper end face of the connecting block 55.

[0049] In this embodiment, the rotating cylinder 51 is installed in the support frame 11 through the bearing, so that the rotating disk 12 can be rotated on the upper surface of the support frame 11. When the second electric push rod 54 drives the connecting block 55 to move, the connecting block 55 can drive the second rack 56 to move. The movement of the second rack 56 can drive the second gear 52 to rotate. That is, the second gear 52 drives the rotating disk 12 to rotate through the rotating cylinder 51. When the second electric push rod 54 drives the second rack 56 to move to the maximum stroke position, the moving component needs to drive the mounting plate 15 to move away from the support frame 11. Then, the second electric push rod 54 performs a reset action on the second rack 56. During the reset process, the position of the upper limit frame 13 of the rotating disk 12 is consistent with the position of the limit frame 13 when the second rack 56 is at the maximum stroke position. After the second rack 56 completes the reset, the moving component continues to operate. Among them, a horizontal plate 57 is fixedly installed on the lower end face of the support frame 11, and a horizontal block 58 is fixedly installed on the side wall of the second rack 56 facing the horizontal plate 57. By inserting the horizontal block 58 into the horizontal plate 57, the movement of the second rack 56 is limited, so that the second rack 56 can move stably. The dust collector 59 is fixedly installed on the upper surface of the base plate 10. A suction pipe is fixedly installed on the side wall of the dust collector 59. One end of the suction pipe passes through the rotating cylinder 51, the rotating disk 12 and the lifting disk 24. A suction block 60 is fixedly installed at the through end of the suction pipe. The dust collector 59 can suck up the dust from the cut circuit board through the suction pipe and the suction block 60, so that the dust during the circuit board cutting can be absorbed into the dust collector 59 and prevent the dust from spreading everywhere. In practical use, the operator first places the circuit board to be cut into the limiting groove of the limiting frame 13 away from the mounting frame 16, so that one end of the circuit board abuts against the limiting block 14 in the limiting groove. Then, the rotating component on the lower end face of the support frame 11 drives the rotating disk 12 to rotate at intervals, so that the limiting frame 13 without circuit boards moves to a position away from the mounting frame 16 in sequence, making it easier for the operator to place the circuit boards in sequence. When the limiting frame 13 with circuit boards moves to below the mounting plate 15, the pushing component on the upper end face of the base plate 10 drives the pushing plate 17 to move towards the support frame 11. The pushing plate 17 drives the pushing block 19 to move through the pushing rod 18, ensuring that one end of the circuit board abuts tightly against the limiting block 14. Then, the moving component drives the mounting frame 16 to move towards the support frame 11. The mounting plate 15 is moved by the limiting component, which drives the lifting plate 21 to move down. The lifting plate 21 drives the rubber block through the limiting frame 13 and presses against the circuit board to achieve circuit board limiting. The mounting plate 15 continues to move, and the dividing component on its lower end cuts the circuit board after limiting. After cutting, the pushing component drives the pushing plate 17 away from the circuit board, and the moving component drives the mounting plate 15 to reset. The limiting component releases the pressure on the circuit board, and the rotating disk 12 rotates again at intervals to move the cut circuit board away from the mounting frame 16. The worker takes out the finished product and puts in a new circuit board to be cut, completing one work cycle. During the cutting process, the dust collector 59 absorbs the cutting dust through the suction pipe and the suction block 60 to prevent it from scattering.

[0050] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
