Description

Technical Field

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

[0002] The production process of network transformers involves several key stages, including winding, casing insertion, wire cutting, welding, and testing. Among these, accurately inserting the wound coil into the casing and then cutting the lead wire is a crucial prerequisite for ensuring the accuracy of subsequent processing. Specifically, after the coil is wound, it must be precisely placed in a pre-designed slot within the casing. The wire leading from the slot must be cut to the designed length for subsequent welding to components such as pins. During this process, the relative positional stability of the wire and the slot is paramount. If the wire shifts or detaches from the slot during cutting, it will not only result in non-standard cut lengths but may also cause problems such as wire tangling and misalignment, thus affecting the smooth progress of subsequent welding processes and even leading to product scrap, severely restricting production efficiency and product qualification rates.

[0003] Currently, most existing devices for cutting wires after they are installed in the casing of network transformers only have a single wire-cutting function, that is, cutting the wires using a wire-cutting module, but lack an effective clamping and positioning mechanism for the wires. In actual operation, when the wire-cutting module contacts the wires and applies shearing force, the wires will be subjected to a reaction force along the shearing direction. Due to the lack of clamping constraints, the wires are very likely to move upwards along the wire groove under the influence of this force, or even detach from the wire groove. This displacement phenomenon is more pronounced, especially for wires with thinner diameters and softer materials.

[0004] Displacement or detachment of wires can trigger a series of chain problems: First, the length deviation of the cut wires is too large, failing to meet the dimensional requirements of subsequent welding, requiring manual secondary trimming or adjustment, increasing process costs and time; Second, wires detached from the wire trough may become entangled with other wires, leading to chaotic wiring and damaging the electrical performance of the network transformer; Third, to solve the above problems, manual monitoring and intervention are often required during production, which not only reduces the level of automated production but also makes it difficult to ensure operational consistency, further affecting the stability of product quality. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a network transformer wire-cutting device.

[0006] A network transformer wire cutting device designed for this purpose includes a machine base and fixing elements, a wire clamping module and a wire cutting module mounted on the machine base.

[0007] The fixing element is used to fix the network transformer;

[0008] The clamping module is used to clamp the two sides of the network transformer and to clamp and fix the wire of the coil.

[0009] The wire-cutting module is used to cut the wire on the outside of the wire clamping module.

[0010] Preferably, the wire-cutting module includes a moving module and a wire-cutting assembly; the moving module is connected to the wire-cutting assembly and is used to drive the wire-cutting assembly to move relative to the fixed element;

[0011] The wire-cutting assembly includes a base, a movable base, a fixed blade, a moving blade, and a first linear drive element;

[0012] Two fixed blades are provided and are spaced apart on the base;

[0013] The movable base is movable left and right relative to the base; two movable blades are provided and are spaced apart on the movable base;

[0014] The fixed blade and the moving blade on the same side are fitted together; the fixed blade has a plurality of first tangent grooves arranged in the left-right direction; the moving blade has a plurality of second tangent grooves corresponding to the first tangent grooves arranged in the left-right direction; the opposing first tangent grooves and second tangent grooves are interconnected.

[0015] The first linear drive element is used to drive the movable seat to move left and right relative to the base.

[0016] Preferably, the mobile module includes a first mobile platform that moves left and right relative to the fixed element, a second linear drive element for driving the first mobile platform to move, and a third linear drive element disposed on the first mobile platform.

[0017] The third linear drive element is fixedly connected to the base and drives the base to move up and down relative to the fixed element.

[0018] Preferably, the mobile module uses an existing multi-axis robotic arm.

[0019] Preferably, the wire clamping module includes at least a pneumatic clamping element, and the two movable ends of the pneumatic clamping element are connected to clamping plates;

[0020] The pneumatic clamping element can drive the two clamping plates to clamp the front and rear sides of the network transformer, thereby clamping and fixing the wires extending from the wire groove.

[0021] Preferably, the clamping module further includes a second moving platform that moves left and right relative to the fixed element, and a fourth linear drive element for driving the second moving platform to move.

[0022] Preferably, the wire clamping module and the wire cutting module are spaced apart on the left and right, and the fixing element is disposed between the two.

[0023] Preferably, the fixing element is a pneumatic gripper.

[0024] Compared with the prior art, this utility model, through the reasonable setting of fixing elements, wire clamping module and wire cutting module, can significantly improve the problems of wire displacement and detachment in the existing wire cutting process. The specific beneficial effects are as follows:

[0025] First, the fixing components provide stable support and positioning for the network transformer, ensuring that its overall position does not shift during wire cutting, thus providing a reliable reference for subsequent wire clamping and cutting processes. This design fundamentally reduces wire position deviation caused by transformer body sway, laying the foundation for improved processing accuracy.

[0026] Secondly, the wire clamping module effectively constrains and fixes the wire by clamping it on both sides of the network transformer. This clamping method directly counteracts the reaction force generated during wire cutting, preventing the wire from moving upwards along the wire groove or detaching from it, fundamentally solving the wire displacement problem caused by the lack of wire clamping function in existing devices. Furthermore, the clamping force and range of the wire clamping module can be flexibly adjusted for different specifications of network transformers, demonstrating good adaptability.

[0027] Finally, the wire-cutting module cuts the wire outside the clamping module. Since the wire is already stably fixed, the stability and accuracy of the cutting process are significantly improved. This not only ensures that the cut length meets design standards, reducing the need for manual secondary trimming and lowering process costs and time, but also avoids problems such as wire tangling and misalignment, ensuring the smooth progress of subsequent welding processes and improving product qualification rate and quality stability. Furthermore, the collaborative work of all modules in the device enables automated wire-cutting operations, reducing manual intervention, improving production efficiency, and meeting the needs of large-scale, high-quality production of network transformers.

[0041] See Figures 1-5 A network transformer wire cutting device includes a machine base 50 and a fixing element 10, a wire clamping module 20, and a wire cutting module 30 disposed on the machine base 50; the fixing element 10 is used to fix the network transformer 100; the wire clamping module 20 is used to clamp the two sides of the network transformer 100 and clamp and fix the wire of the coil; the wire cutting module 30 is used to cut the wire outside the wire clamping module 20.

[0042] The working principle of this network transformer wire-cutting device is as follows:

[0043] First, the robotic arm transfers the wound coil to the machine 50 and precisely places it into the fixing element 10. The fixing element 10 then activates to firmly fix the network transformer 100, ensuring that it will not shift its position during subsequent processing and providing a stable operating basis for the wire clamping and cutting processes.

[0044] Subsequently, the wire clamping module 20 begins to operate, moving to both sides of the network transformer 100 and precisely aligning with the wire leading out from the coil. The clamping structure then clamps and secures the wire from both sides. At this point, the wire is firmly restrained, effectively preventing displacement or detachment from the wire channel due to force during wire cutting.

[0045] Finally, the wire cutting module 30 is activated after the wire clamping module 20 completes its clamping action. It moves to the outside of the wire clamping module 20, that is, the outside of the part of the wire that is clamped, aligns with the position of the wire to be cut, and cuts the wire through the closing action of the wire cutting blade. Since the wire is stably fixed by the wire clamping module 20, the wire cutting process can be completed accurately and stably, ensuring that the cut length meets the process requirements.

[0046] In this utility model, the clamping module 20 can clamp and fix the wire by cooperating with the fixing element 10, or the clamping module 20 can be directly clamped to the side wall of the network transformer 100 to fix the wire.

[0047] See Figures 2 to 4 The wire-cutting module 30 includes a movable module 300 and a wire-cutting assembly 40; the movable module 300 is connected to the wire-cutting assembly 40 and is used to drive the wire-cutting assembly 40 to move relative to the fixed element 10; the wire-cutting assembly 40 includes a base 410, a movable base 430, a fixed blade 420, a movable blade 440, and a first linear drive element 450; the fixed blade 420 is provided with two blades and is arranged at a distance from front to back on the base 410; the movable base 430 is arranged to move left and right relative to the base 410; the movable blade 440 is provided with... Two blades are placed on the movable base 430, spaced apart front to back; a fixed blade 420 and a movable blade 440 on the same side are fitted together front to back; the fixed blade 420 has a plurality of first tangent grooves 421 arranged in the left-right direction; the movable blade 440 has a plurality of second tangent grooves 441 arranged in the left-right direction corresponding to the first tangent grooves 421; the opposing first tangent grooves 421 and second tangent grooves 441 are interconnected; the first linear drive element 450 is used to drive the movable base 430 to move left and right relative to the base 410.

[0048] The working principle of the wire cutting module 30 is as follows:

[0049] After the wire clamping module 20 completes the clamping and fixing of the wire, the wire cutting module 30 begins to work. At this time, the wire feeding clamp (i.e., wire clamp) of the coil entering the shell plays a role. As a component that holds the two wire bundles at the front and back of the coil when it enters the shell, it continues to hold these two wire bundles during the wire cutting stage and straightens them to prepare for subsequent wire cutting.

[0050] Next, the moving module 300 starts, first moving the wire cutting assembly 40 laterally relative to the fixed element 10, so that it accurately reaches above the fixed element 10. Subsequently, the moving module 300 continues to move the wire cutting assembly 40 downward. During this process, the wire straightened by the wire feed clamp smoothly enters the first cutting groove 421 on the fixed blade 420 and the second cutting groove 441 on the moving blade 440 in the wire cutting assembly 40 (since the lower ends of the first cutting groove 421 and the second cutting groove 441 are open, it is convenient for the wire to enter). The first cutting groove 421 and the second cutting groove 441 are interconnected, ensuring that the wire is stably placed in the two cutting grooves.

[0051] Subsequently, the first linear drive element 450 drives the movable seat 430 to move left and right relative to the base 410. Because the moving blade 440 is mounted on the movable seat 430 and the fixed blade 420 is mounted on the base 410, with the fixed blade 420 and moving blade 440 on the same side being fitted together (there are two fixed blades 420 spaced apart on the base 410, and two moving blades 440 spaced apart on the movable seat 430), the moving blade 440 moves left and right relative to the fixed blade 420 along with the movable seat 430. When the moving blade 440 moves relative to the fixed blade 420, the first tangent groove 421 and the second tangent groove 422 move relative to each other, thereby cutting the wire within the two tangent grooves.

[0052] After the wire cutting is completed, the first linear drive element 450 drives the movable seat 430 to reset, and the moving blade 440 also returns to its initial position. The moving module 300 first drives the wire cutting assembly 40 to move upward, away from the wire area, and then drives it to move laterally back to its initial position, waiting for the next wire cutting command.

[0053] Throughout the process, the moving module 300 precisely controls the horizontal and downward movement of the wire cutting assembly 40, ensuring the accuracy of the wire cutting position; the wire feeding clamp straightens the wire, providing a reliable guarantee for the wire to smoothly enter the cutting groove; and the cooperation between the fixed blade 420 and the moving blade 440, as well as the drive of the first linear drive element 450, achieves efficient and precise cutting of the wire.

[0054] In this invention, other existing wire-cutting structures can also be used in conjunction with the wire clamping module 20.

[0055] In this invention, the first tangent groove 421 and the second tangent groove 441 can be configured with an upper opening. When the wire is being cut, the base 410 moves from bottom to top, allowing the wire to enter the tangent groove.

[0056] In this invention, the first tangent groove 421 and the second tangent groove 441 are correspondingly provided with the wire groove 101 of the network transformer 100 so that the corresponding wires enter the corresponding tangent grooves to achieve individual cutting.

[0057] See Figure 2 The moving module 300 includes a first moving platform 310 that moves left and right relative to the fixed element 10, a second linear drive element 320 for driving the first moving platform 310 to move, and a third linear drive element 330 disposed on the first moving platform 310. The third linear drive element 330 is fixedly connected to the base 410 and drives the base 410 to move up and down relative to the fixed element 10. The function of the moving module 300 is to precisely control the position of the wire cutting assembly 40: the second linear drive element 320 drives the first moving platform 310 to move left and right, driving the wire cutting assembly 40 to move laterally, so that the first cutting groove 421 of the fixed blade 420 and the second cutting groove 441 of the moving blade 440 precisely correspond to the wire; the third linear drive element 330 drives the base 410 to move up and down. When moving down, the wire enters the cutting groove. After the wire is cut, it moves up to reset, providing a guarantee for the smooth execution of the cutting action and the connection of subsequent processes.

[0058] In this invention, the mobile module 300 adopts an existing multi-axis robotic arm.

[0059] See Figure 3 and Figure 5 The wire clamping module 20 includes at least a pneumatic clamping element 210, with clamping plates 211 connected to its two movable ends. The pneumatic clamping element 210 drives the two clamping plates 211 to clamp the front and rear sides of the network transformer 100, thereby clamping and fixing the wire extending from the wire groove 101. The function of the wire clamping module 20 is to drive the two clamping plates 211 through the pneumatic clamping element 210, clamping them to the front and rear sides of the network transformer 100, thus firmly clamping and fixing the wire extending from the wire groove 101, preventing the wire from shifting or detaching during the wire cutting process. The pneumatic clamping element 210 can be an existing pneumatic gripper, such as a parallel pneumatic gripper, whose two movable ends can stably drive the clamping plates 211 to open and close, ensuring reliable clamping of the wire.

[0060] See Figure 1 and Figure 2The wire clamping module 20 further includes a second moving platform 220 that moves left and right relative to the fixed element 10, and a fourth linear drive element 230 for driving the second moving platform 220 to move. The fourth linear drive element 230 drives the second moving platform 220 to move left and right relative to the fixed element 10, thereby moving the pneumatic clamping element 210 and the clamping plate 211. After the wire coil is inserted into the shell, the fourth linear drive element 230 drives the second moving platform 220 to move to a preset position. Then, the pneumatic clamping element 210 drives the two clamping plates 211 to clamp the front and rear sides of the network transformer 100, firmly fixing the wire extending from the wire groove 101 and preventing the wire from shifting or coming off during the wire cutting process.

[0061] In this invention, the wire clamping module 20 and the wire cutting module 30 are spaced apart on the left and right, with the fixing element 10 positioned between them. This arrangement allows the wire clamping module 20 to clamp and fix the wires of the network transformer on the fixing element 10, while the wire cutting module 30 can precisely align the wires from the side, reducing interference between their movements, ensuring efficient coordination between the wire clamping and cutting processes, and improving the overall stability and accuracy of the wire cutting operation.

[0062] In this invention, the fixing element 10 is a pneumatic gripper.

[0063] In this invention, the first linear drive element 450, the second linear drive element 320, the third linear drive element 330, and the fourth linear drive element 230 are cylinders.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
