Technical Field
[0001] This utility model relates to the field of cutting device technology, and more specifically, to a wire cutting device for circuit board molds with good stability. Background Technology
[0002] A circuit board, also known as a printed circuit board or printed circuit board, makes circuits miniaturized and more intuitive, playing an important role in the mass production of fixed circuits and the optimization of electrical appliance layout.
[0003] When operators are producing and processing circuit boards, they often need to use circuit board molds to improve the production and processing efficiency. Because the internal structure of circuit boards is very precise, the processing accuracy requirements for circuit board molds are very high. Therefore, in the existing technology, circuit board molds are often cut using wire cutting. Although existing wire cutting devices have high-precision cutting capabilities, it is difficult for current wire cutting devices on the market to stably clamp the circuit board molds during operation, resulting in unstable processing and affecting the processing effect. Therefore, it is necessary to improve them. Utility Model Content

[0007] A clamping mechanism is disposed inside the fixed block;
[0008] The clamping mechanism includes a threaded rod, the outer surface of which is movably sleeved with the interior of a fixed block. A screwing block is fixedly sleeved at the right end of the threaded rod, the outer surface of which is movably sleeved with the interior of the fixed block. A moving ring is threadedly sleeved on the outer surface of the threaded rod inside the short groove. A moving block is hinged to the outer surface of the moving ring. A connecting block is movably sleeved inside the top of the moving block. A clamping block is fixedly installed at the bottom end of the connecting block. The outer surface of the clamping block is movably connected with the interior of the fixed block. A limit block is movably connected inside the clamping block. The outer surface of the limit block is fixedly connected with the interior of the fixed block.
[0009] As a preferred technical solution of this utility model, a moving block is fixedly installed at the bottom end of the fixed block, and a long plate is movably connected to the outer surface of the moving block. Long slots are opened on both the left and right sides of the front of the long plate. A drive motor is fixedly installed on the left side of the long plate, and a lead screw is fixedly sleeved at the other end of the output shaft of the drive motor. Both ends of the lead screw are movably sleeved with the inside of the long plate, and the outer surface of the lead screw is sleeved with the internal thread of the moving block.
[0010] As a preferred technical solution of this utility model, the bottom end of the long plate is movably connected to a top plate, and the cutting device body is fixedly installed at the rear of the top end of the top plate. Sliding grooves are provided on both the left and right sides of the top end of the top plate, and sliding blocks are movably connected inside the sliding grooves. The top end of the sliding blocks is fixedly connected to the bottom end of the long plate.
[0011] As a preferred embodiment of this utility model, a fixing plate is fixedly installed at the top of the top plate, and rollers are movably installed inside the fixing plate.
[0012] As a preferred embodiment of this utility model, a base is fixedly installed at the bottom end of the top plate, and a reinforcing rod is provided on the base.
[0013] As a preferred embodiment of this utility model, a power motor is fixedly installed on the front of the top plate, and a screw is fixedly sleeved on the other end of the output shaft of the power motor. A toothed plate is threaded onto the outer surface of the screw, and the outer surface of the toothed plate is movably connected to the interior of the top of the top plate.
[0014] As a preferred embodiment of this utility model, a bevel gear is meshed with the outer surface of the toothed plate, a rotating rod is fixedly installed at the top of the bevel gear, and a fixed shaft is movably sleeved inside both the rotating rod and the bevel gear. The bottom end of the fixed shaft is fixedly connected to the top end of the top plate, and the other end of the rotating rod is movably connected to the inside of the long groove.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This type of wire cutting device for circuit board molds with good stability features a threaded rod that is threaded into the internal threads of four moving rings. When the threaded rod rotates, it drives the four moving rings to move to the right. At the same time, the four moving rings drive the four movable blocks to move. Then, the tops of the four movable blocks drive the four clamping blocks to move downward along the inside of the fixed block through the four connecting blocks. Since the limiting block is movablely connected to the inside of the clamping block, the four clamping blocks are more stable during movement and their movement stroke is limited. Subsequently, the four clamping blocks cooperate with the fixed block to fix the circuit board mold in the downward movement, thereby enabling stable clamping of the circuit board mold.
[0017] 2. This type of wire cutting device for circuit board molds with good stability features a screw and a toothed plate with internal threaded connection. When the screw rotates, it drives the toothed plate to move forward along the inside of the top plate. Since the toothed plate meshes with two bevel gears, the toothed plate will drive two rotating rods to rotate in opposite directions around two fixed axes through the two bevel gears. During this process, the other end of the two rotating rods will squeeze the inside of the two long grooves, thereby causing the long plate to drive the two sliders to move backward along the inside of the grooves. This allows the circuit board to be cut at different positions according to the usage requirements. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figures 1 to 8 As shown, this utility model provides a wire cutting device for circuit board molds with good stability, comprising:
[0029] Fixing block 1, with a short groove 2 at its top;
[0030] The clamping mechanism is located inside the fixed block 1;
[0031] The clamping mechanism includes a threaded rod 3, the outer surface of which is movably connected to the interior of the fixed block 1. A screwing block 4 is fixedly connected to the right end of the threaded rod 3, the outer surface of which is movably connected to the interior of the fixed block 1. A moving ring 5 is threadedly connected to the outer surface of the threaded rod 3 inside the short groove 2. A moving block 6 is hinged to the outer surface of the moving ring 5. A connecting block 7 is movably connected to the top of the moving block 6. A clamping block 8 is fixedly installed at the bottom of the connecting block 7. The outer surface of the clamping block 8 is movably connected to the interior of the fixed block 1. A limiting block 9 is movably connected to the interior of the clamping block 8. The outer surface of the limiting block 9 is fixedly connected to the interior of the fixed block 1.
[0032] When the operator turns the turning block 4, it will cause the threaded rod 3 to rotate inside the fixed block 1. Since the inside of the moving ring 5 is threadedly connected to the outer surface of the threaded rod 3, when the threaded rod 3 rotates, it will drive the moving block 6 to move through the moving ring 5. At this time, the other end of the moving block 6 will drive the clamping block 8 to move through the connecting block 7. Since the outer surface of the clamping block 8 is movably connected to the inside of the fixed block 1, and the inside of the clamping block 8 is movably connected to the outer surface of the limiting block 9, the clamping block 8 can only move up and down. At this time, the clamping block 8 will move downward under the drive of the connecting block 7. Due to the design of the limiting block 9, the movement of the clamping block 8 can be made more stable and its movement stroke can be limited. Then, the clamping block 8 will cooperate with the fixed block 1 to clamp and fix the circuit board mold during the downward movement.
[0033] Among them, a moving block 10 is fixedly installed at the bottom of the fixed block 1, and a long plate 11 is movably connected to the outer surface of the moving block 10. Long slots 12 are opened on both the left and right sides of the front of the long plate 11. A drive motor 13 is fixedly installed on the left side of the long plate 11. A lead screw 14 is fixedly sleeved at the other end of the output shaft of the drive motor 13. Both ends of the lead screw 14 are movably sleeved with the inside of the long plate 11, and the outer surface of the lead screw 14 is sleeved with the internal thread of the moving block 10.
[0034] Due to the design of the long plate 11, the movement of the moving block 10 is limited, so that the moving block 10 can only move left and right. When the drive motor 13 is running, the lead screw 14 will rotate. Since the outer surface of the lead screw 14 is connected to the internal thread of the moving block 10, when the lead screw 14 rotates, it will drive the moving block 10 to move to the right along the outer surface of the long plate 11.
[0035] The bottom end of the long plate 11 is movably connected to the top plate 15. The cutting device body 16 is fixedly installed at the rear of the top end of the top plate 15. Slide grooves 17 are provided on both the left and right sides of the top end of the top plate 15. A slider 18 is movably connected inside the slide groove 17. The top end of the slider 18 is fixedly connected to the bottom end of the long plate 11.
[0036] Due to the design of the slide 17, the movement of the entire long plate 11 will be limited by the slider 18, so that it can only move back and forth. When the cutting device body 16 is running, the cutting line on the cutting device body 16 will be able to cut the circuit board mold.
[0037] The top plate 15 is fixedly installed with a fixing plate 19, and a roller 20 is movably installed inside the fixing plate 19.
[0038] Since the roller 20 is movably installed inside the fixed plate 19, the roller 20 can rotate inside the fixed plate 19. Due to the design of the roller 20, it can provide good support for the circuit board, making the circuit board more stable when moving. Furthermore, since the roller 20 can rotate, it will not affect the movement of the circuit board.
[0039] The bottom of the top plate 15 is fixedly installed with a base 21, and a reinforcing rod 22 is provided on the base 21.
[0040] Due to the design of the base 21, it can provide good support for the top plate 15 as a whole, and due to the design of the reinforcing rod 22, it can enhance the structural strength of the base 21.
[0041] Among them, a power motor 23 is fixedly installed on the front of the top plate 15, and a screw 24 is fixedly sleeved on the other end of the output shaft of the power motor 23. A toothed plate 25 is threadedly sleeved on the outer surface of the screw 24, and the outer surface of the toothed plate 25 is movably connected to the interior of the top end of the top plate 15.
[0042] When the power motor 23 is running, the screw 24 will rotate. Since the inside of the toothed plate 25 is threadedly connected to the outer surface of the screw 24, when the screw 24 rotates, it will drive the toothed plate 25 to move back and forth along the inside of the top of the top plate 15.
[0043] Among them, a bevel gear 26 is meshed on the outer surface of the toothed plate 25, and a rotating rod 27 is fixedly installed on the top of the bevel gear 26. A fixed shaft 28 is movably sleeved inside both the rotating rod 27 and the bevel gear 26. The bottom end of the fixed shaft 28 is fixedly connected to the top of the top plate 15, and the other end of the rotating rod 27 is movably connected to the inside of the long groove 12.
[0044] Since the toothed plate 25 is meshed with the two bevel gears 26, when the toothed plate 25 moves forward, the toothed plate 25 will drive the two bevel gears 26 to rotate in the opposite direction around the two fixed shafts 28. At the same time, the two rotating rods 27 will rotate in the opposite direction under the drive of the two bevel gears 26. At this time, the other end of the two rotating rods 27 will squeeze the inside of the long groove 12, thereby causing the long plate 11 to move backward as a whole.
[0045] Working principle and usage process of this utility model:
[0046] First, the operator places the circuit board mold inside the fixed block 1. Then, the operator turns the turning block 4, causing the threaded rod 3 to rotate inside the fixed block 1. Since the outer surface of the threaded rod 3 is threadedly engaged with the inner threads of the four moving rings 5, the rotation of the threaded rod 3 will drive the four moving rings 5 to move simultaneously. At this time, the four moving rings 5 will drive the four movable blocks 6 to move to the right. Simultaneously, the tops of the four movable blocks 6 will drive the four connecting blocks 7 to move. Then, the four connecting blocks 7 will drive the four clamping blocks 8 to move downward along the inside of the fixed block 1. At the same time, the inside of the four clamping blocks 8 will move downward along the outer surface of the four sets of limit blocks 9. Due to the design of the four sets of limit blocks 9, the vertical movement of the four clamping blocks 8 is limited, making the vertical movement of the four clamping blocks 8 more stable. Subsequently, the four clamping blocks 8 will cooperate with the inside of the fixed block 1 during the downward movement to clamp and fix the circuit board mold, thereby achieving the function of stable clamping of the circuit board mold.
[0047] When the operator needs to cut the circuit board mold, the operator first starts the cutting device body 16, and then starts the drive motor 13. At this time, the lead screw 14 will rotate. Since the outer surface of the lead screw 14 is connected to the internal thread of the moving block 10, when the lead screw 14 rotates, it will drive the moving block 10 to move. Since the outer surface of the moving block 10 is movably connected to the outer surface of the long plate 11, the movement of the moving block 10 will be limited by the long plate 11, which will cause the moving block 10 to only move left and right. At this time, the moving block 10 will move to the right along the outer surface of the long plate 11 under the drive of the lead screw 14. At the same time, the moving block 10 will drive the circuit board to move to the right as a whole through the fixed block 1. During this process, the circuit board mold will come into contact with the cutting wire on the cutting device body 16 and be cut, thereby achieving the function of automatically cutting the circuit board mold.
[0048] When the operator needs to cut different positions on the circuit board, the operator starts the power motor 23. The screw 24 then rotates. Since the outer surface of the screw 24 is threaded into the inner surface of the toothed plate 25, its rotation drives the toothed plate 25. Because the outer surface of the toothed plate 25 is movably connected to the inner surface of the top of the top plate 15, the toothed plate 25 moves forward along the inner surface of the top of the top plate 15 under the drive of the screw 24. Since the outer surface of the toothed plate 25 meshes with the outer surfaces of two bevel gears 26, its forward movement drives the two bevel gears 26 to rotate in opposite directions around the two fixed shafts 28. The two rotating rods 27 rotate in opposite directions around the two fixed shafts 28, driven by the two bevel gears 26. At this time, the other ends of the two rotating rods 27 will squeeze and push the interior of the two long grooves 12, thereby causing the long plate 11 to move as a whole. The two sliders 18 will move under the drive of the long plate 11. Due to the design of the slide groove 17, the movement of the two sliders 18 will be limited, so that they can only move back and forth. At this time, the two sliders 18 will move backward along the interior of the slide groove 17 under the drive of the long plate 11 as a whole, thereby achieving the function of cutting the circuit board at different positions according to the usage requirements.
