Description

Technical Field

[0001] This utility model relates to the field of network transformer manufacturing technology, and in particular to a wire trimming device for network transformer manufacturing. Background Technology

[0002] In the field of core component manufacturing for network communication equipment, network transformers, as key components for achieving signal isolation, impedance matching, and electromagnetic interference suppression, directly determine the communication stability and reliability of the equipment through the precision of their manufacturing process. Among these processes, the magnetic winding process is one of the core steps in network transformer production. This process requires specialized winding equipment to wind enameled wire onto the surface of a magnetic ring according to a preset number of turns and winding rules, ultimately forming a coil structure with specific electrical properties.

[0003] From the perspective of subsequent processing and application scenarios, the wound coils are mainly divided into two major application directions: First, some coils need to be directly soldered and assembled with circuit boards to form an integrated circuit module; Second, other coils need to be encased in a shell to achieve physical protection and insulation isolation. For this type of coil, the error range of tap length control can be appropriately relaxed, and secondary adjustments can be made in combination with the shell assembly requirements.

[0004] However, in the fabrication of wire coils directly soldered to circuit boards, a pressing technological challenge exists: to ensure precise alignment between the wire coil and the circuit board pads, the taps extending from both sides of the wire coil must be trimmed, and it is strictly required that the trimmed lengths of the two taps be identical. Deviations in tap length can lead not only to problems such as incomplete or incorrect soldering, but also to uneven force on the pins, potentially reducing the reliability of the connection between the wire coil and the circuit board. This can affect the signal transmission performance of the network transformer and even cause the entire communication equipment to malfunction.

[0005] In summary, in the production scenario of directly soldering circuit boards to network transformer coils, existing equipment cannot efficiently and accurately complete the synchronous wire cutting and length consistency control of the left and right taps of multiple coils. This has become a key bottleneck restricting the improvement of network transformer production efficiency and product quality, and there is an urgent need to develop a new processing equipment or process solution that can solve the above problems. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a wire-cutting device for the production of network transformers.

[0007] A wire-cutting device for the production of network transformers designed for this purpose includes a machine base, a wire clamping module, a wire cutting module, and a moving module.

[0008] The wire clamping module includes a fixed base, and clamping components for clamping wires are provided on the left and right sides of the fixed base; the clamping components include two pneumatic grippers spaced apart on the left and right.

[0009] The wire cutting module includes a first linear drive element, a mounting base, and automatic shears mounted on the machine base; the mounting base is mounted on the moving shaft of the first linear drive element; two automatic shears are provided and spaced apart from each other on the left and right.

[0010] The first linear drive element is used to drive the mounting base and the automatic shears to move back and forth relative to the machine table, so as to drive the automatic shears to extend between the two pneumatic grippers of the same clamping assembly to cut the wire;

[0011] The moving module is used to drive the wire clamping module to move relative to the machine platform.

[0012] Preferably, the mounting base is provided with a wire clamping element.

[0013] Preferably, the clamping module further includes a second linear drive element; the moving shaft of the second linear drive element is fixedly connected to the fixed base; the second linear drive element is fixedly mounted on the moving module.

[0014] Preferably, the moving module includes a third linear drive element for driving the wire clamping module to move left and right relative to the machine platform.

[0015] Preferably, the moving module further includes a fourth linear drive element, which is used to drive the wire clamping module to move up and down relative to the machine platform.

[0016] Preferably, the mobile module employs a multi-axis robotic arm.

[0017] Compared with existing technologies, this invention achieves precise processing of network transformer coil taps through the coordinated design of a wire clamping module and a wire cutting module. The wire clamping module's mounting base has clamping components on both sides, each containing two spaced-apart pneumatic claws that stably clamp the taps on both sides of the coil, preventing tap displacement during cutting. Simultaneously, the two automatic shears of the wire cutting module are precisely matched to the pneumatic claws of the clamping components, and a first linear drive element drives the automatic shears to extend between the two pneumatic claws of the same clamping component to cut the wire. This ensures that the left and right taps are trimmed on the same cutting plane, effectively controlling the post-cut tap length error. This fully meets the stringent requirements for tap size accuracy when directly soldering the coil to a circuit board, reducing the risk of incomplete or incorrect soldering and improving the stability of the network transformer's communication performance.

[0029] See Figures 1-3 A wire-cutting device for network transformer production includes a machine base 10, a wire clamping module 20, a wire-cutting module 30, and a moving module 40. The wire clamping module 20 includes a fixed base 220, and clamping components 230 for clamping wire are provided on the left and right sides of the fixed base 220. The clamping components 230 include two air grippers 231 spaced apart from each other. The wire-cutting module 30 includes a first linear drive element 310, a mounting base 320, and automatic scissors 330 mounted on the machine base 10. The mounting base 320 is mounted on the moving shaft of the first linear drive element 310. Two automatic scissors 330 are provided and spaced apart from each other. The first linear drive element 310 is used to drive the mounting base 320 and the automatic scissors 330 to move back and forth relative to the machine base 10, so as to drive the automatic scissors 330 to extend between the two air grippers 231 of the same clamping component 230 to cut the wire. The moving module 40 is used to drive the wire clamping module 20 to move relative to the machine base 10.

[0030] This wire-cutting device for network transformer production achieves automated and efficient wire cutting of network transformer coil taps through precise coordination of the wire clamping module, the wire cutting module, and the moving module. Its specific working principle is as follows:

[0031] First, after the device is started, it enters the feeding stage. The moving module 40 first drives the wire clamping module 20 to move precisely relative to the machine base 10 to the preset feeding position. At this time, the two sets of clamping components 230 on the left and right sides of the fixed base 220 of the wire clamping module 20 are simultaneously in the clamping state. The two air claws 231 in each set of clamping components 230, which are set apart on the left and right, remain open. After the coil (the coil with the wire wound) is in place, the two sets of clamping components 230 move synchronously, and the air claws 231 close and clamp and fix the taps on the left and right sides of the coil respectively. Through the stable clamping of the air claws 231, the displacement of the taps during the subsequent trimming process can be directly avoided, providing a basic guarantee for the wire trimming accuracy. Thus, the clamping and fixing of the coil taps and the feeding positioning are completed.

[0032] Next, the position switching stage begins. Driven by the moving module 40, the wire clamping module 20, with the tap already clamped and fixed, moves precisely from the "feeding position" to the preset "wire cutting position". Because the moving module 40 has high-precision displacement control capabilities, it ensures that when the wire clamping module 20 reaches the wire cutting position, the positions of its left and right clamping components 230 are completely aligned with the position of the automatic scissors 330 of the wire cutting module 30, providing positional assurance for the subsequent precise wire cutting action of the wire cutting module 30.

[0033] Subsequently, the wire cutting action is performed. After the wire clamping module 20 is stably stopped at the wire cutting position, the wire cutting module 30 receives the working signal and starts: the first linear drive element 310 set on the machine base 10 drives its moving shaft, which drives the mounting base 320 and the two left-right spaced automatic scissors 330 mounted on the mounting base 320 to move relative to the machine base 10 in the front-back direction. Because the moving module 40 has achieved precise alignment between the wire clamping module and the wire cutting module, the automatic scissors 330 can smoothly extend into the space between the two pneumatic grippers 231 of each clamping component 230 (i.e., the gap where the tap is clamped); when the automatic scissors 330 reach the preset wire cutting height, they quickly close and cut the tap fixed by the clamping component 230, and the two automatic scissors 330 move synchronously to ensure that the cut length of the taps on the left and right sides of the coil is consistent.

[0034] In this invention, the mounting base 320 is provided with a coil clamping element 50, which can be an existing pneumatic gripper. The coil clamping element 50 is mounted on the mounting base 320 and positioned between the two clamping components 230 of the coil clamping module 20. Its core function is to assist in positioning from the coil body (magnetic ring) level, improving the stability and accuracy of the wire cutting process: before the wire cutting action begins, the coil clamping element 50 closes first, stably clamping the coil magnetic ring located between the two clamping components 230, thus fixing the coil body; at the same time, the pneumatic grippers 231 of the two clamping components 230 simultaneously clamp the coil tap, forming a double fixing structure of "body + tap"—the coil clamping element 50 fixing the magnetic ring can prevent the coil from shifting as a whole, and the pneumatic grippers 231 fixing the tap can prevent the tap from shifting. This double protection ensures that the coil position remains accurate and unchanged during the wire cutting process.

[0035] After the wire cutting module 30 completes the tap cutting action, when the first linear drive element 310 drives the mounting base 320 to reset and move, the coil clamping element 50 still maintains the clamping state of the coil magnetic ring, and synchronously drives the coil that has completed the wire cutting to move with the mounting base 320 until the coil is accurately transferred to the preset unloading position; finally, the coil clamping element 50 opens and releases the coil, so that the coil can be smoothly unloaded without the need for additional mechanism to assist in the transfer. This not only enhances the positioning stability during wire cutting, but also further improves the automation level and efficiency of the unloading process of the device.

[0036] See Figure 2 The clamping module 20 further includes a second linear drive element 210; the moving shaft of the second linear drive element 210 is fixedly connected to the fixed base 220; the second linear drive element 210 is fixedly mounted on the moving module 40. The second linear drive element 210 is the core component of the wire clamping module 20, enabling flexible position adjustment. One end of it is fixedly mounted on the moving module 40, and the other end's moving shaft is fixedly connected to the fixed base 220 of the wire clamping module 20. Its core function is to drive the fixed base 220 to move the two clamping components 230 in the front-back direction, thereby flexibly changing the position of the wire coil. During the feeding stage, the relative position of the clamping components 230 and the wire coil to be fed can be adjusted by moving them back and forth, making it easy for the pneumatic gripper 231 to accurately align and clamp the wire coil tap. During the wire cutting stage, it can work with the displacement of the moving module 40 to further fine-tune the relative distance between the wire coil and the wire cutting module 30, ensuring that the automatic scissors 330 of the wire cutting module 30 can accurately extend between the pneumatic grippers 231 to complete the wire cutting, thus ensuring the convenience of feeding and clamping and the accuracy of the wire cutting displacement.

[0037] In this invention, the moving module 40 includes a third linear drive element for driving the wire clamping module 20 to move left and right relative to the machine base 10. The third linear drive element is the core component of the moving module 40 to realize the left and right displacement of the wire clamping module. Its core function is to drive the wire clamping module 20 to move precisely in the left and right direction relative to the machine base 10: during the feeding stage, it can drive the wire clamping module 20 to a position aligned with the wire coil feeding point, so that the clamping assembly 230 can quickly align with the wire coil being fed; during the wire cutting stage, it can accurately move the wire clamping module 20 from its initial position to the wire cutting station that is compatible with the wire cutting module 30, ensuring that the wire cutting action is carried out smoothly.

[0038] In this invention, based on the embodiment of the third linear drive element, the moving module 40 further includes a fourth linear drive element, which drives the wire clamping module 20 to move up and down relative to the machine base 10. As an important component of the moving module 40, the fourth linear drive element works in conjunction with the third linear drive element (left-right displacement). Its core function is to drive the wire clamping module 20 to move precisely up and down relative to the machine base 10. On one hand, the height of the wire clamping module 20 can be flexibly adjusted according to the height specifications of the coil to be processed, enabling the clamping assembly 230 to accurately align with coil taps of different heights, improving the adaptability of the feeding clamp. On the other hand, during the wire cutting stage, it can work in conjunction with the left-right displacement of the third linear drive element to further fine-tune the vertical alignment accuracy between the wire clamping module 20 and the wire cutting module 30 (automatic scissors 330), ensuring that the automatic scissors 330 can accurately extend into the preset wire cutting height between the pneumatic grippers 231.

[0039] In this invention, the mobile module 40 employs a multi-axis robotic arm.

[0040] In this invention, the first linear drive element 310 and the second linear drive element 210 are cylinders or other existing linear drive elements.

[0041] In this invention, the third linear drive element can be a cylinder as the driving component. For example, a common standard cylinder uses compressed air to drive a piston to move linearly within the cylinder, thereby causing the load to shift left and right. In similar automated equipment, cylinders, with their advantages of simple structure, rapid action, and low cost, can efficiently adjust the horizontal position of components. In this device, using a cylinder as the third linear drive element, the wire clamping module 20 can be quickly moved left and right on the machine base 10, achieving coarse adjustment of the coil position to adapt to different workflow requirements.

[0042] For the fourth linear drive element, an electric linear actuator can be used. The electric linear actuator internally consists of a motor, a lead screw and nut assembly, etc. The rotation of the motor drives the lead screw to rotate, thereby causing the nut and the connected linear actuator to move linearly, achieving precise vertical displacement control. In many precision machining equipment, electric linear actuators are widely used due to their high positioning accuracy, stable output force, and precise stroke control. In this wire trimming device, an electric linear actuator is selected as the fourth linear drive element, which can precisely drive the wire clamping module 20 to move up and down relative to the machine base 10. Whether in the feeding and clamping stage for coils of different heights, or in the vertical alignment adjustment of the wire clamping module 20 and the wire trimming module 30 during wire trimming, its high precision characteristics ensure the accurate execution of each process of the device.

[0043] In this invention, the automatic scissors 330 are existing pneumatic scissors or other types of scissors.
