Description

Technical Field

[0001] This utility model relates to the technical field of high-frequency electronic transformer production equipment, specifically to a lead cutting device suitable for the production of high-frequency electronic transformers. Background Technology

[0002] An electronic transformer is an electronic device that converts alternating mains voltage into direct current (DC), and then outputs a high-frequency AC voltage through semiconductor switching devices, electronic components, and high-frequency transformer windings. Its working principle is based on an AC-DC-AC inverter circuit. As a high-frequency electronic transformer, the high-frequency electronic transformer requires its leads to be cut to the required length during production. However, research on existing lead-cutting devices has revealed that current devices often use magnets to attract and fix the dragged leads during cutting. This method is ineffective at securing the leads, causing them to easily fall off and affecting cutting stability, thus limiting the device's practicality.

[0003] Chinese Patent Publication No. CN221414830U discloses a lead wire cutting device for high-frequency electronic transformer production. During operation, a cylinder is activated to push a pusher frame to the left, moving it below a support frame. This causes the second pressing block to contact the first pressing block, which in turn pushes it downwards, causing the connecting rod and locking rod to move downwards. The downward movement of the connecting rod causes the clamping plate to move downwards, fixing the lead wire between the clamping plate and the pusher frame. Simultaneously, the locking rod moves downwards and contacts the locking port. The second spring resets, pushing the locking rod into the locking port to lock the clamping plate. Then, the cylinder resets and moves to the right, moving the pusher frame and indirectly causing the lead wire to move to the right. Next, an electric telescopic rod is activated, moving downwards and causing the cutting shears to move downwards to cut the lead wire. Afterwards, the electric telescopic rod causes the cutting shears to reset. At this time, the pusher frame moves to the right, causing the unlocking rod to insert into the locking port. The second ball pushes the first ball to move to the left, causing the locking rod to move to the left and the second spring to deform. When the locking rod completely disengages from the locking port, the first spring resets, pushing the second pressing block to reset, causing the clamping plate to reset and releasing the cut lead wire. The above operation can then be repeated to cut leads in batches. Rotating the handle drives the rotating disk and screw to rotate, adjusting the position of the unlocking rod. However, after the lead wire is cut, the clamping plate in this device needs to guide the lead wire back to the clamping plate before it can be clamped again for the next lead wire cut, which results in poor continuity of the lead wire cutting device.

[0004] Therefore, the clamping device needs to be improved so that the lead wire cutting device can continuously guide the lead wire. Utility Model Content

[0005] To address the aforementioned problems, a lead cutting device suitable for the production of high-frequency electronic transformers is provided. By setting up a conveying mechanism, which includes a first conveying roller and a second conveying roller, when the first and second conveying rollers rotate, a first clamping block and a third clamping block abut against the continuous end of the clamped lead, and a second clamping block and a fourth clamping block abut against the cut end of the clamped lead. This solves the problem of poor continuity of the lead cutting device caused by the need to guide the lead back to the clamping plate after the lead is cut in order to clamp the lead again.

[0006] To address the problems of existing technologies, this utility model provides a lead cutting device suitable for the production of high-frequency electronic transformers, comprising a first platform and a cutting mechanism. A second platform is disposed on the first platform, and the cutting mechanism is disposed on the second platform. A conveying mechanism is disposed between the first platform and the second platform, the conveying mechanism comprising a first conveying roller and a second conveying roller. A first positioning rod and a second positioning rod are disposed on the first platform, the first conveying roller is sleeved on the first positioning rod, and the second conveying roller is sleeved on the second positioning rod. A first clamping rod and a second clamping rod are fixedly connected around the periphery of the first conveying roller, and a third clamping rod and a fourth clamping rod are fixedly connected around the periphery of the second conveying roller. When the first conveying roller and the second conveying roller rotate to the point where the first clamping rod and the third clamping rod abut, the second clamping rod and the fourth clamping rod are in abutting state, at which time the cutting mechanism cuts the lead located between the first clamping rod and the second clamping rod.

[0007] Preferably, the cutting mechanism includes a first motor and a cutter; the first motor is mounted on a second platform; the output shaft of the first motor is connected to a telescopic rod, which passes through the second platform and is fixedly connected to the cutter.

[0008] Preferably, the first clamping rod, the second clamping rod, the third clamping rod, and the fourth clamping rod are provided with an elastic mechanism; the elastic mechanism includes a support base, a return spring, and an elastic clamping block; the elastic clamping block is sleeved on the support base, and the return spring is disposed between the elastic clamping block and the support base.

[0009] Preferably, the first platform is provided with guide rollers to guide the lead wire before it enters the conveying mechanism.

[0010] Preferably, a storage mechanism is provided on the first platform; the storage mechanism includes a storage slot and a storage box; the storage slot is opened on the first platform, and the storage box is placed in the storage slot for storing the cut lead wire.

[0011] Preferably, a drive mechanism is provided on the second platform; the drive mechanism includes a second motor, a first roller and a second roller, the second motor is provided on the second platform; the output shaft of the second motor is fixedly connected to the first roller; gears are provided below the first roller and the second roller, and the first roller and the second roller are meshed; the first roller drives the first conveyor roller to rotate through a transmission belt, and the second roller drives the second conveyor roller to rotate through a transmission belt.

[0012] Preferably, the first platform is provided with supporting table legs.

[0013] Preferably, the first positioning rod and the second positioning rod are provided with anti-detachment blocks to prevent the first conveying roller and the second conveying roller from detaching.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. In this utility model, by setting a second platform on the first platform and placing the cutting mechanism on the second platform, and with the setting of the conveying mechanism and the clamping rod, the conveying roller can rotate automatically during operation. With the cooperation of the clamping rod, the subsequent lead wire is automatically guided to a suitable position for the next cutting. There is no need for manual pulling of the lead wire again, which effectively ensures the continuity of the device operation and greatly improves the production efficiency.

[0016] 2. In this utility model, an elastic mechanism is provided inside the clamping rod. When the first clamping rod and the third clamping rod abut against each other to clamp the lead wire, the lead wire squeezes the elastic clamping block. The elastic clamping block is compressed by the force to return the spring, which can better fit the lead wire and achieve stable clamping of the lead wire. After the cutting operation is completed, the return spring pushes the elastic clamping block back to its original position to prepare for the next clamping operation, making the lead wire clamping more reliable and ensuring the smooth progress of the cutting process.

[0017] 3. This utility model is equipped with a storage mechanism. When the lead wire is cut by the cutting mechanism, the cut lead wire falls into the storage box placed in the storage slot under the action of gravity and other forces. This realizes the collection and storage of the cut lead wire, which is convenient for subsequent unified processing, avoids the chaos caused by the lead wire scattering, and optimizes the production environment.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-6As shown: A lead wire cutting device suitable for the production of high-frequency electronic transformers includes a first platform 1 and a cutting mechanism 4. A second platform 3 is disposed on the first platform 1, and the cutting mechanism 4 is disposed on the second platform 3. A conveying mechanism 2 is disposed between the first platform 1 and the second platform 3. The conveying mechanism 2 includes a first conveying roller 23 and a second conveying roller 24. A first positioning rod 21 and a second positioning rod 22 are disposed on the first platform 1. The first conveying roller 23 is sleeved on the first positioning rod 21, and the second conveying roller 24 is sleeved on the second positioning rod 22. A first clamping rod 231 and a second clamping rod 232 are fixedly connected around the periphery of the first conveying roller 23, and a third clamping rod 241 and a fourth clamping rod 242 are fixedly connected around the periphery of the second conveying roller 24. When the first conveying roller 23 and the second conveying roller 24 rotate to the point where the first clamping rod 231 and the third clamping rod 241 abut, the second clamping rod 232 and the fourth clamping rod 242 are in abutting state. At this time, the cutting mechanism 4 cuts the lead wire located between the first clamping rod 231 and the second clamping rod 232.

[0027] In existing technologies, after a lead wire is cut, it needs to be manually pulled back to the clamping mechanism before operation can continue, resulting in poor continuity of the device. To address this issue, in a lead wire cutting device suitable for the production of high-frequency electronic transformers, a second platform 3 is set on a first platform 1, and the cutting mechanism 4 is placed on the second platform 3. During operation, the first conveying roller 23 and the second conveying roller 24 rotate. When the first clamping rod 231 and the third clamping rod 241 abut, the second clamping rod 232 and the fourth clamping rod 242 also abut. At this time, the cutting mechanism 4 cuts the lead wire located between the first clamping rod 231 and the second clamping rod 232. Afterward, the conveying rollers can continue to rotate, and the subsequent lead wire is automatically guided to a suitable position for the next cut using the cooperation of the clamping rods, eliminating the need for manual pulling of the lead wire again, thus ensuring the continuity of the device operation.

[0028] Reference Figure 1 and Figure 5 As shown: The cutting mechanism 4 includes a first motor 41 and a cutter 42; the first motor 41 is mounted on the second platform 3; the output shaft of the first motor 41 is connected to a telescopic rod, which passes through the second platform 3 and is fixedly connected to the cutter 42.

[0029] In the lead cutting device suitable for the production of high-frequency electronic transformers, the first motor 41 in the cutting mechanism 4 is set on the second platform 3, and its output shaft is connected to the telescopic rod. The telescopic rod passes through the second platform 3 and is fixedly connected to the cutter 42. When working, the first motor 41 starts and drives the output shaft to rotate, which in turn causes the telescopic rod connected to it to perform telescopic movement. The telescopic rod drives the cutter 42 to move synchronously, thereby realizing the cutter 42 to cut the lead between the first clamping rod 231 and the second clamping rod 232.

[0030] Reference Figures 1-4 As shown: The first clamping rod 231, the second clamping rod 232, the third clamping rod 241 and the fourth clamping rod 242 are provided with an elastic mechanism 5; the elastic mechanism 5 includes a support base 51, a return spring 52 and an elastic clamping block 53; the elastic clamping block 53 is sleeved on the support base 51, and the return spring 52 is disposed between the elastic clamping block 53 and the support base 51.

[0031] When the first clamping rod 231 and the third clamping rod 241 abut against each other to clamp the lead wire, the lead wire squeezes the elastic clamping block 53. The elastic clamping block 53 is then compressed by the force to compress the return spring 52, thereby allowing the elastic clamping block 53 to better fit the lead wire and achieve stable clamping of the lead wire. After the cutting operation is completed, as the first clamping rod 231 and the third clamping rod 241 separate, the return spring 52 pushes the elastic clamping block 53 back to its original position, ready for the next clamping operation.

[0032] Reference Figure 1 As shown: The first platform 1 is provided with guide rollers 6 to guide the lead wire before it enters the conveying mechanism 2.

[0033] The guide roller 6 on the first platform 1 guides the lead wire before it enters the conveying mechanism 2. When the device is working, the lead wire contacts the guide roller 6. As the lead wire moves, the guide roller 6 changes the direction of the lead wire by rolling, allowing the lead wire to enter the conveying mechanism 2 accurately and ensuring a more precise position of the lead wire during subsequent conveying and cutting operations.

[0034] Reference Figure 6 As shown: A storage mechanism 7 is provided on the first platform 1; the storage mechanism 7 includes a storage slot 71 and a storage box 72; the storage slot 71 is opened on the first platform 1, and the storage box 72 is placed in the storage slot 71 for storing the cut lead wire.

[0035] After the lead wire is cut by the cutting mechanism 4, the cut lead wire falls under the action of gravity and falls into the storage box 72 placed in the storage slot 71, thereby realizing the collection and storage of the cut lead wire for easy subsequent unified processing.

[0036] Reference Figures 1-6 As shown: A drive mechanism 8 is provided on the second platform 3; the drive mechanism 8 includes a second motor 81, a first roller 82 and a second roller 83, the second motor 81 is provided on the second platform 3; the output shaft of the second motor 81 is fixedly connected to the first roller 82; a gear 84 is provided below the first roller 82 and the second roller 83, and the first roller 82 and the second roller 83 are meshed; the first roller 82 drives the first conveying roller 23 to rotate through a transmission belt, and the second roller 83 drives the second conveying roller 24 to rotate through a transmission belt.

[0037] The second motor 81 is mounted on the second platform 3, and its output shaft is fixedly connected to the first roller 82. When the second motor 81 starts, it drives the first roller 82 to rotate. The first roller 82 and the second roller 83 are meshed together through the gear 84 below. Thus, when the first roller 82 rotates, it drives the second roller 83 to rotate synchronously. Then, the first roller 82 drives the first conveyor roller 23 to rotate through the transmission belt, and the second roller 83 drives the second conveyor roller 24 to rotate through the transmission belt. This allows the first conveyor roller 23 and the second conveyor roller 24 to work together to cooperate with subsequent wire clamping and cutting operations.

[0038] Reference Figure 2 As shown: The first platform 1 is provided with table legs 9 for support.

[0039] The table legs 9 installed under the first platform 1 bear the weight of the entire device by contacting the ground, keeping the device in a stable position and providing a solid foundation for the normal operation of each component on the device.

[0040] Reference Figure 2 As shown: The first positioning rod 21 and the second positioning rod 22 are provided with anti-detachment blocks 10 to prevent the first conveying roller 23 and the second conveying roller 24 from detaching.

[0041] The anti-detachment blocks 10 provided on the first positioning rod 21 and the second positioning rod 22 restrict the movement of the first conveying roller 23 and the second conveying roller 24 in their axial direction, preventing the first conveying roller 23 and the second conveying roller 24 from detaching from the corresponding positioning rod due to unexpected circumstances during operation. This ensures that the conveying rollers can rotate stably on the positioning rods, guaranteeing the normal operation of the entire conveying mechanism 2 to cooperate with subsequent operations such as lead wire cutting.

[0042] In a lead cutting device suitable for the production of high-frequency electronic transformers, a second platform 3 is provided on a first platform 1, and a cutting mechanism 4 is placed on the second platform 3. Between the first platform 1 and the second platform 3, there is a conveying mechanism 2 containing a first conveying roller 23 and a second conveying roller 24, which are respectively sleeved on a first positioning rod 21 and a second positioning rod 22. The first conveying roller 23 is connected to a first clamping rod 231 and a second clamping rod 232, and the second conveying roller 24 is connected to a third clamping rod 241 and a fourth clamping rod 242. Each clamping rod contains an elastic mechanism 5 containing a support base 51, a return spring 52, and an elastic clamping block 53. During operation, the second motor 81 in the drive mechanism 8 on the second platform 3 is started, driving the first roller 82 connected to it to rotate. Through the meshing of the gear 84, the second roller 83 rotates synchronously, and then drives the first conveying roller 23 and the second conveying roller 24 to rotate through the transmission belt. When the first conveying roller 23 and the second conveying roller 24 rotate to the first clamping rod 231 and the third clamping rod 242, the first conveying roller 23 rotates. When the holding rod 241 abuts, and the second clamping rod 232 and the fourth clamping rod 242 also abut, the first motor 41 in the cutting mechanism 4 starts, and its output shaft drives the telescopic rod to extend and retract, so that the cutter 42 moves to cut the lead wire located between the first clamping rod 231 and the second clamping rod 232. During clamping, the lead wire squeezes the elastic clamping block 53, which compresses the return spring 52 to achieve stable clamping. After cutting, the return spring 52 pushes the elastic clamping block 53 to return to its original position. The guide roller 6 on the first platform 1 can guide the lead wire before entering the conveying mechanism 2 to enter accurately. After cutting, the lead wire falls into the storage box 72 in the storage groove 71 on the first platform 1 by gravity and is collected and stored. The table leg 9 support device under the first platform 1 ensures stable placement. The anti-detachment block 10 on the first positioning rod 21 and the second positioning rod 22 prevents the conveying roller from accidentally detaching and ensures the normal operation of the conveying mechanism 2 to continuously complete the conveying, clamping and cutting of the lead wire. This device does not require manual pulling of the lead wire again, ensuring the continuous operation of the device.

[0043] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
