Description

Technical Field

[0001] This invention relates to the field of wire mesh processing equipment technology, specifically a positioning and welding processing device for a multi-material wire mesh production system. Background Technology

[0002] Wire mesh is a mesh structure made of threads arranged in both longitudinal and transverse directions. Wire mesh has applications in various fields, including industry, agriculture, science and technology, and national defense.

[0003] In order to fully utilize the functional characteristics of each material, such as improving the strength or conductivity of the mesh, enriching the function of the mesh, and reducing the cost of the mesh, the existing technology uses fine wires of multiple materials to form a mesh-like mesh.

[0004] When multiple materials are combined to form a wire mesh, it is difficult to achieve a strong weld during the processing due to the differences in the surface properties of each material. This is especially true when the materials contain both metal and non-metal components, making it difficult to splice them into a mesh through direct welding.

[0005] Besides welding, existing technologies commonly employ two processing methods: textile and injection molding. In textile processing, the two different materials used result in weak bonding and insufficient rigidity of the yarns. Injection molding, on the other hand, suffers from low processing efficiency. Therefore, both of these existing processes have certain limitations.

[0006] For the production and processing of composite wire mesh made of multiple materials, a new process and production equipment need to be designed. Summary of the Invention

[0007] To address the aforementioned technical issues, the applicant designed a "sandwich-style" bonding method for welding wires of various materials into a mesh. Specifically, the mesh consists of upper and lower layers of horizontal wires, with a U-shaped longitudinal middle wire (hereinafter referred to as "middle wire") sandwiched between the two layers of horizontal wires. The lower layer of horizontal wires has a groove, and the middle wire fits perfectly into the groove, allowing the two layers of horizontal wires to adhere. The upper and lower layers of horizontal wires are made of the same or similar materials, facilitating welding and thus forming a mesh structure in which the longitudinal middle wire is welded and fixed between the upper and lower layers of horizontal wires. In addition, the upper and lower frame horizontal wires and the U-shaped middle wire form a stable mesh structure. The U-shaped structure ensures that the outermost bottom wire and other horizontal wires will not easily detach at the U-shaped bend after welding. The opposite end of the middle wire at the U-shaped bend is the protruding end of the horizontal wire. Numerous ends are connected in series or parallel and welded together on the outside of the horizontal wires, similarly preventing the longitudinal middle wire from detaching from the outermost top horizontal wire.

[0008] Based on the above-mentioned production method, the present invention provides a positioning and welding processing device in a multi-material wire mesh production system, which positions the lower horizontal wire, the U-shaped middle wire and the upper horizontal wire and then welds and fixes them into a wire mesh.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A positioning and welding processing device for a multi-material wire mesh production system includes a middle wire transfer device, a positioning mold, and a welding device. The middle wire transfer device is used to transfer the U-shaped middle wire, which was placed in the mold consisting of a mold core box and a mold core in the previous process, to the positioning mold; the positioning mold is used to provide positioning for the lower layer of horizontal wires and the U-shaped middle wire; the welding device is used to weld the upper and lower layers of horizontal wires.

[0010] The positioning mold is installed on a ring guide rail, which is connected to a ring guide rail power mechanism. The ring guide rail power mechanism drives the ring guide rail to move continuously in a cycle. The ring guide rail drives the positioning mold to circulate in the middle wire transfer station and the welding station. The upper surface of the positioning mold has multiple rows of horizontal grooves and multiple columns of vertical grooves. The horizontal grooves and vertical grooves are arranged to intersect each other. The middle wire transfer device feeds the U-shaped middle wire into the vertical groove of the positioning mold. The horizontal groove of the positioning mold is used to position the lower horizontal wire.

[0011] This invention addresses the applicant's "sandwich-style" joining method by designing a specialized positioning mold and a continuous operating structure, thereby achieving automated positioning and efficient welding operations.

[0012] A U-shaped wire is placed in two symmetrically placed mold cores, which are located in a mold core box. Only one end of the U-shape protrudes from the mold core. The wire transfer platform is responsible for pulling the U-shaped wire out of the mold core and precisely placing it in the vertical groove of the positioning mold. The wire transfer platform includes multiple rows of wire hooks. The front end of each wire hook is a pointed structure, and a stepped wire hook groove is provided behind the pointed structure. The pointed tip cuts into the gap left by the wire in the mold core box, allowing the U-shaped bottom of the wire to slide into the wire hook groove without damaging the wire. The wire hooks are connected to wire hook sliding plates, which are connected to wire hook sliding drive mechanisms. The wire hook sliding drive mechanisms drive the wire hook sliding plates to move linearly, thereby driving the wire hooks to move linearly. The number of wire hooks installed on the wire hook sliding plates is the same as the number of U-shaped wires to be pulled.

[0013] To prevent the middle wire from slipping out of the groove of the hook beak during the pulling process, the hook beak is connected to the hook beak shaft, and a hook beak pressure spring is connected to the hook beak shaft. The hook beak pressure spring maintains a slight compression between the upper hook beak and the hook beak sliding plate. Adjusting the elasticity of the pressure spring to a suitable strength allows the middle wire to easily squeeze out the gap between the upper hook beak and the hook beak sliding plate, allowing the middle wire to enter its hook groove. Under the action of the hook beak pressure spring, the upper hook beak is pressed back and closed with the hook beak sliding plate, which can prevent the hook beak from opening automatically and prevent the middle wire from slipping out of the groove.

[0014] The medium-fiber transfer device includes a comb guide positioning device located at the medium-fiber transfer station. The comb guide positioning device includes multiple rows of parallel medium-fiber comb guides. The medium-fiber comb guides are parallel to the horizontal grooves of the positioning mold. The lower part of the medium-fiber comb guides has multiple n-shaped opening groove structures, and the n-shaped opening groove structures are arranged one-to-one with the vertical grooves of the positioning mold. The n-shaped opening grooves of the medium-fiber comb guides, together with the vertical grooves, form a cavity to limit the position of the medium-fiber in the horizontal direction.

[0015] The two ends of the comb guide are respectively connected to the comb guide support device. The comb guide support device includes a comb guide support frame, on which a comb guide positioning groove is formed. A comb guide compression spring is connected in the comb guide positioning groove. The comb guide compression spring is connected to a comb guide plunger. The comb guide plunger presses down on the comb guide, thereby providing elastic pressure to the comb guide. The comb guide can be squeezed upward and automatically rebounds.

[0016] The comb guide support frame has a channel for the upper horizontal wires to pass through. The comb guide support frame is higher than the positioning mold to avoid affecting the circulation operation of the positioning mold.

[0017] The hook beak sliding plate has a sloping wedge-shaped middle wire comb guide at one end near the upper beak of the hook wire, and the top of the middle wire comb guide wedge can be inserted into the lower part of the middle wire comb guide.

[0018] The above structure is designed to facilitate the smooth completion of the wire hooking action. Specifically, as the wire hooking beak sliding plate moves from one side of the positioning mold to the side near the mold core box, it drives the middle wire comb guide wedge to move together. The top of the middle wire comb guide wedge is inserted into the lower part of the middle wire comb guide. This pushes the miniature bearings at both ends of the middle wire comb guide to roll on the inclined surface of the middle wire comb guide wedge. Constrained by the frame of the middle wire comb guide positioning groove, the middle wire comb guide can only be pushed upwards, and the middle wire comb guide compression spring is compressed by the middle wire comb guide plunger. This process separates the lower plane of the medium wire comb guide from the upper plane of the positioning mold, allowing it to pass through the hook beak sliding plate and the hook beak. The hook beak continues to move forward until it contacts the U-shaped bending part of the medium wire in the mold core box, which is fixed by the medium wire transfer tooling positioning platform. The medium wire easily squeezes open the gap between the relatively moving hook beak and the hook beak sliding plate, allowing the medium wire to enter the groove of the hook beak. Under the action of the hook beak compression spring, the hook beak is pressed back and closes with the hook beak sliding plate, completing the hook beak hooking process.

[0019] After the hooking beak sliding plate, carrying the hooking beak, hooks the U-shaped center wire, the hooking beak sliding plate drive mechanism reverses its movement, pulling a row of U-shaped center wires out of the mold core. During the extraction process, the center wire comb guide wedge retracts along with the hooking beak sliding plate, and the center wire comb guide is sequentially pressed back close to the positioning mold by the center wire comb guide compression spring. Each "n"-shaped bridge hole of the center wire comb guide aligns with the "u"-shaped opening vertical groove on the positioning mold, forming an "O"-shaped hole in the middle with an additional center wire, thus successfully completing the hooking action.

[0020] To ensure that the middle wire moves to the welding station along with the upper and lower coils, a middle wire positioning block is provided to temporarily press the middle wire before welding is completed, thus restricting the middle wire's vertical freedom. Specifically, multiple rows of middle wire positioning and fixing suction blocks are fixedly connected to the positioning mold. These suction blocks are parallel to the horizontal grooves of the positioning mold and embedded within it. Multiple suction blocks and middle wire comb guides are arranged alternately, distributed in the intervals or outer spaces of the horizontal wires. The middle wire positioning and fixing suction blocks are used to connect to the middle wire positioning blocks. Each middle wire positioning block is a thin, elongated strip arranged horizontally with multiple n-shaped grooves that just avoid the cross-section of the middle wire. These blocks are attracted and connected by the suction blocks to press the middle wire.

[0021] The central wire positioning block is equipped with a corresponding central wire positioning and removal adsorption block for its rotation. The central wire positioning and removal adsorption block is fixedly connected to the central wire positioning block longitudinal moving platform, which is connected to the central wire positioning block transverse moving platform. After the upper and lower horizontal wires are welded, the central wire positioning block loses its function. After it leaves the welding station along with the central wire, the central wire positioning block longitudinal moving platform raises the central wire positioning and removal adsorption block to prevent it from bumping into the welding device during the transverse movement of the central wire positioning and removal adsorption block. The central wire positioning and removal adsorption block falls down with the central wire positioning and removal adsorption block. The electromagnetic attraction of the central wire positioning and removal adsorption block in the positioning mold is turned off, and the electromagnetic attraction of the central wire positioning and removal adsorption block is turned on. The central wire positioning block moves again with the central wire positioning and removal adsorption blocks longitudinal and transverse moving platforms to the top of the central wire transfer station to position the central wire of the next set of positioning molds.

[0022] The positioning and fixing adsorption block and the positioning and removal adsorption block for the central wire can be adsorbed using electromagnetic attraction or air suction. When using electromagnetic attraction, the positioning and fixing adsorption block and the positioning and removal adsorption block for the central wire are electromagnets, and the adsorption, positioning or removal of the central wire positioning block is achieved by energizing and de-energizing the electromagnet.

[0023] The medium wire transfer station is equipped with a fixed crossbar, which is a horizontal plate slightly higher than the tip of the hook wire beak. When the hook wire beak sliding plate moves to insert the tip of the hook wire beak into the lower part of the crossbar, the hook wire beak sliding plate drive motor stops, the medium wire positioning block longitudinal platform moves down and places the medium wire positioning block on the corresponding medium wire positioning fixed adsorption block, fixing the medium wire pulled out by the hook wire beak. The hook wire beak sliding plate drive motor restarts and continues to pull the medium wire. The crossbar presses down on the hook wire beak and presses up the inclined surface, pressing the hook wire beak compression spring, so that the hook wire beak rotates around its own hook wire beak rotation axis. The front end of the hook wire beak, the upper hook wire beak, is raised. Under the fixation of the medium wire positioning block, the medium wire cannot move up with the upper hook wire beak, forcing the U-shaped medium wire to disengage from the hook wire beak front end hook wire groove, leaving the entire row of U-shaped medium wires in the vertical groove of the set horizontal wire positioning mold.

[0024] The welding device is located at the welding station and includes a welder that welds the upper and lower horizontal wires together.

[0025] The welding station is equipped with a welding clamping device to clamp the three layers of material: the upper horizontal wire, the middle wire, and the lower horizontal wire, so that these three are aligned longitudinally and laterally within the positioning mold, especially the upper and lower horizontal wires are accurately aligned on the welding surface.

[0026] The welding clamping device includes a welding clamping power mechanism and a welding clamping frame connected thereto. The welding clamping power mechanism drives the welding clamping frame to move up and down.

[0027] The welding device is selected from one of the following: laser welding device, ultrasonic welding device, or hot plate welding device.

[0028] The beneficial effects achieved by this invention are: This invention, in conjunction with a multi-material wire mesh production system, can flexibly transfer the U-shaped middle wire located in the mold core to the positioning mold, and precisely position the three layers of materials—upper horizontal wire, middle wire, and lower horizontal wire—to complete subsequent precise welding.

[0029] In the reciprocating horizontal linear motion of the wire transfer device of this invention, the wire hook beak, through the cooperation of the compression spring and a special structure, realizes the four-step function of automatically opening and closing the wire hook beak to clamp the wire, and then opening and releasing the wire after being dragged, so as to transfer the U-shaped wire to the positioning mold and make the wire accurately positioned.

[0030] This invention features an optimized structure, ensuring quality and efficiency during processing, and enabling automated and efficient production. Attached Figure Description

[0033] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] Example: like Figure 1 , Figure 2As shown, a positioning and welding processing device for a multi-material wire mesh production system includes a middle wire transfer device, a positioning mold 5, and a welding device. The middle wire transfer device is used to pull the U-shaped middle wire 1-1 from the mold core 1-2 in the mold core box 1-3 transferred from the previous process onto the positioning mold 5; the positioning mold 5 is used to provide positioning for the lower horizontal wire 6 and the U-shaped middle wire 1-1; the welding device 17 is used to weld the upper and lower horizontal wires.

[0035] The positioning mold 5 is mounted on the annular guide rail via annular guide rail sliders 7. The annular guide rail is connected to an annular guide rail power mechanism, which is an annular guide rail drive motor 13. The annular guide rail drive motor 13 drives the annular guide rail to rotate, and the annular guide rail drives the annular guide rail sliders 7 and the positioning mold 5 to circulate between the wire transfer station and the welding station. The annular guide rail drive motor 13 moves intermittently. During the welding process of the welder 17, the annular guide rail drive motor 13 stops. After welding is completed, the annular guide rail drive motor 13 drives the synchronous belt, and the synchronous belt drives all the annular guide rail sliders 7 on the annular guide rail to move one position together. The above-mentioned annular guide rail and annular guide rail slider 7 transmission structure is a conventional structure of the prior art and will not be described in detail here.

[0036] The annular guide rail slider 7 installed on the vertical annular guide rail has the same center distance in the horizontal direction as the center distance of the lower horizontal wire. During the process of the annular guide rail slider 7 turning into linear motion, its upward movement, together with the positioning mold 5, moves the upper and lower horizontal wires forward, thereby realizing the positioning of the lower horizontal wire.

[0037] The positioning mold 5 is a mold fixed on the annular guide rail slider 7. Its upper surface has multiple rows of horizontal grooves and multiple columns of vertical grooves. The middle wire transfer device sends the U-shaped middle wire into the vertical groove of the positioning mold 5. The horizontal groove of the positioning mold 5 is used to position the lower horizontal wire.

[0038] like Figure 3 As shown, the U-shaped center wire 1-1 is placed in two symmetrically placed mold cores 1-2. The mold cores 1-2 are placed in the mold core box 1-3 for circulation, with only the U-shaped bent end protruding from the mold core 1-2. Multiple sets of mold cores 1-2 are located in the same mold core box 1-3. The center wire transfer tooling positioning platform 2 positions the center wire transfer tooling 1 on one side of the center wire transfer device. The center wire transfer device is responsible for pulling out a horizontal row of U-shaped center wires from the mold cores 1-2 and accurately placing them in the vertical groove of the positioning mold 5. Specifically, it will be as follows: Figure 3The mold core box 1-3, which carries multiple rows of U-shaped middle wires 1-1, is sent to the middle wire transfer fixture positioning platform 2 for positioning. The opening of the mold core box 1-3 faces away from the middle wire pulling fixture. After the middle wire transfer fixture positioning platform 2 fixes the mold core box 1-2 through the mold core box clamping cylinder 3, the position of the mold core box 1-3 is adjusted so that the hook beak 8-1 in the middle wire pulling fixture is directly facing the bending part of a row of middle wires in the U-shaped middle wires 1-1, so that the hook beak 8 can hook and pull out the U-shaped middle wires 1-1.

[0039] like Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, the wire transfer device includes multiple rows of wire hooks 8. The front end of the wire hook 8 is a pointed upper wire hook 8-1. A stepped wire hook groove 8-2 is provided behind the pointed structure. The pointed tip cuts into the gap left in the mold core box for the wire 1-1. Without damaging the wire 1-1, the U-shaped bottom of the wire 1-1 can be slid into the wire hook groove 8-2 of the wire hook 8. The hook beak 8 is connected to the hook beak sliding plate 10. The square wave structure of the hook beak sliding plate 10 directly faces the hook beak upper beak 8-1. The width of the raised square wave is consistent with that of the hook upper beak, so that this part can enter the reserved groove space in the middle wire box. The hook beak sliding plate 10 is connected to the hook beak sliding drive mechanism, which is a hook beak sliding plate drive motor 24. The hook beak sliding plate drive motor 24 drives the hook beak sliding plate 10 to move linearly through a lead screw and nut transmission mechanism, thereby driving the hook beak 8 to move linearly. The number of hook beaks 8 installed on the hook beak sliding plate 10 is the same as the number of U-shaped middle wires 1-1 that need to be pulled.

[0040] To prevent the middle wire 1-1 from sliding out of the groove of the hook beak 8 during the pulling process, the hook beak 8 is connected to the hook beak shaft 8-3, and a hook beak compression spring 8-6 is connected to the hook beak shaft 8-3. The hook beak compression spring 8-6 maintains a slight compression between the upper hook beak 8-1 and the hook beak sliding plate 10. Adjusting the elasticity of the spring to a suitable strength allows the middle wire 1-1 to easily squeeze open the gap between the upper hook beak 8-1 and the hook beak sliding plate 10, allowing the middle wire 1-1 to enter its hook groove 8-2. Under the action of the hook beak compression spring 8-6, the upper hook beak 8-1 is pressed back and closed with the hook beak sliding plate 10, which can prevent the upper hook beak 8-1 from opening automatically and prevent the middle wire 1-1 from sliding out of the hook groove 8-2.

[0041] The medium-fiber transfer device includes a comb guide positioning device located at the medium-fiber transfer station. The comb guide positioning device includes multiple rows of parallel medium-fiber comb guides 22. The medium-fiber comb guides 22 are parallel to the horizontal grooves of the positioning mold 5. The lower part of the medium-fiber comb guides 22 has multiple n-shaped opening groove structures, which are multi-hole bridge structures. The n-shaped opening groove structures are arranged one-to-one with the vertical grooves of the positioning mold 5.

[0042] The two ends of the comb guide 22 are respectively connected to the comb guide support device. The comb guide support device includes a comb guide support frame. The comb guide support frame 21 has a comb guide positioning groove 21-1. A comb guide compression spring 21-2 is connected in the comb guide positioning groove 21-1. One end of the comb guide compression spring 21-2 is fixed to the comb guide support frame 21 by a compression spring fixing bolt. The other end of the comb guide compression spring 21-2 is connected to the comb guide plunger 21-3. The comb guide plunger 21-3 presses down on the comb guide 22, thereby providing elastic support for the comb guide 22. The lower surface of the comb guide 22 is close to the upper surface of the positioning mold 5 under the action of the comb guide compression spring 21-2. Each "n"-shaped bridge hole of the comb guide 22 aligns with the "u"-shaped opening on the positioning mold 5, forming an "O"-shaped through hole in the middle.

[0043] The comb guide support frame 21 has an upper horizontal wire through hole, which is used to guide the upper horizontal wire. The comb guide support frame is higher than the positioning mold to avoid affecting the circulation operation of the positioning mold.

[0044] The hook-beak sliding plate 10 is connected to the middle comb guide wedge 10-1. The middle comb guide wedge 10-1 has a sloping structure at the front end, and the top of the middle comb guide wedge 10-1 can be inserted into the lower part of the middle comb guide 22. The two ends of the middle comb guide 22 are set with "T"-shaped end faces, and a miniature bearing is provided below the "T"-shaped end faces to facilitate the passage of the middle comb guide wedge 10-1 through the lower part of the middle comb guide 22.

[0045] The above structure is designed to facilitate the smooth completion of the wire hooking action. Specifically, as the wire hooking beak sliding plate 10 moves from one side of the positioning mold 5 to the side near the mold core box, it drives the middle wire comb guide wedge 10-1 to move together. The top of the middle wire comb guide wedge 10-1 is inserted below the middle wire comb guide 22. This pushes the miniature bearings at both ends of the middle wire comb guide 22 to roll on the inclined surface of the middle wire comb guide wedge 10-1. Constrained by the frame of the middle wire comb guide positioning groove, the middle wire comb guide 22 can only be lifted upwards, and the middle wire comb guide compression spring 21-2 is compressed by the middle wire comb guide plunger 21-3. This process separates the lower surface of the middle wire comb guide 22 from the upper surface of the positioning mold 5, through which the wire hooking beak sliding plate 10 and the wire hook 8 pass. After the hooking beak slide plate 10, with the hooking beak 8, hooks the U-shaped middle wire, the hooking beak slide plate drive motor 24 reverses its movement, pulling a row of U-shaped middle wires 1-1 out of the mold core. During the extraction process, the middle wire comb guide wedge 10-1 moves backward along with the hooking beak slide plate 10, and the middle wire comb guide 22 is pressed back to be close to the positioning mold 5 by the middle wire comb guide pressure spring 21-2. Each "n"-shaped bridge hole of the middle wire comb guide 22 aligns with the "u"-shaped opening vertical groove on the positioning mold 5, forming an "O"-shaped hole in the middle with an additional middle wire, thus achieving the smooth completion of the hooking action.

[0046] The middle wire transfer station is equipped with a fixed crossbar 9, which is a horizontal plate slightly higher than the tip 8-5 of the hook wire beak. When the hook wire beak sliding plate 10 moves, the tip 8-5 of the hook wire beak is inserted below the crossbar 9. The crossbar 9 presses down on the hook wire beak and raises the inclined surface 8-4, which in turn presses the hook wire beak compression spring 8-6, causing the hook wire beak to rotate around its own hook wire beak rotation axis 8-3. The front end of the hook wire beak, the upper hook wire beak 8-1, is raised. The middle wire 1-1 cannot move up with the upper hook wire beak 8-1 under the fixation of the middle wire positioning block 20, which forces the U-shaped middle wire 1-1 to detach from the hook wire groove 8-2 at the front end of the hook wire beak, leaving the entire row of U-shaped middle wires 1-1 in the vertical groove of the set horizontal wire positioning mold 5.

[0047] like Figure 4 , Figure 5 , Figure 7 As shown, to ensure that the middle wire 1-1 moves to the welding station along with the upper and lower horizontal wires 6, a middle wire positioning block 20 is provided to temporarily press the middle wire 1-1 before welding is completed, so that the middle wire 1-1 also loses its freedom in the vertical direction on the upper surface of the positioning mold. Specifically, multiple rows of middle wire positioning and fixing suction blocks 23 are fixedly connected to the positioning mold 5. The middle wire positioning and fixing suction blocks 23 are parallel to the horizontal groove of the positioning mold 5 and multiple blocks are provided. The middle wire positioning and fixing suction blocks 23 are used to connect the middle wire positioning blocks 20. The middle wire positioning blocks 20 are thin and long strips with multiple n-shaped grooves that just avoid the cross section of the middle wire. The middle wire positioning and fixing suction blocks 23 are made of electromagnets. The middle wire positioning blocks 20 are positioning blocks made of thin-walled magnetic material. Their structure allows each middle wire to be accurately positioned and close to the lower horizontal wire, and embedded in the space left by the lower horizontal wire, the welding pressing device, and the comb guide support frame of the positioning and pushing middle wire comb guide 22.

[0048] The center wire positioning block 20 is correspondingly provided with a center wire positioning and removal adsorption block 19 for its rotation. The center wire positioning and removal adsorption block 19 is fixedly connected to the center wire positioning block longitudinal moving platform 18, which is connected to the center wire positioning block transverse moving platform 16. Both the center wire positioning block longitudinal moving platform 18 and the center wire positioning block transverse moving platform 16 adopt conventional linear screw and slide rail moving mechanisms. After the upper and lower horizontal wires are welded, the center wire positioning block 20 will lose its function. After it leaves the welding position along with the center wire, the center wire positioning block longitudinal moving platform 18 raises the center wire positioning and removal adsorption block 19 to prevent it from hitting the welding device when the center wire positioning and removal adsorption block 19 is brought directly above the center wire positioning block at the welding position by the center wire positioning block transverse moving platform 16. The longitudinal moving platform 18 of the middle wire positioning block, carrying the middle wire positioning and transfer adsorption block 19, falls down. The electromagnetic attraction of the middle wire positioning and fixing adsorption block 23 in the positioning mold is turned off, and the electromagnetic attraction of the middle wire positioning and transfer adsorption block 19 is turned on. The middle wire positioning block 20 moves again to the top of the middle wire transfer station along with the longitudinal moving platform 18 and the transverse moving platform 16 of the middle wire positioning block to position the middle wire of the next set of positioning molds.

[0049] like Figure 1 , Figure 2 As shown, the welding device is located at the welding station and includes a welder 17. The welder 17 welds the upper horizontal wire 4 and the lower horizontal wire 6. Generally, the upper and lower horizontal wires are made of similar materials to facilitate welding, so as to weld and fix the middle wire 1-1 in the upper and lower materials. The welder 17 is selected from existing welding equipment such as laser welder, ultrasonic welder, or hot plate welder.

[0050] The welding station is equipped with a welding clamping device, which includes a welding clamping power mechanism and a welding clamping frame 12 connected thereto. The welding clamping power mechanism drives the welding clamping frame 12 to move up and down. The welding clamping power mechanism is a welding clamping cylinder 11. The welding clamping device is used to clamp the three layers of material: the upper horizontal wire 6, the middle wire 1-1, and the lower horizontal wire 4, so that these three are aligned longitudinally and laterally within the positioning mold 5. In particular, the upper horizontal wire 4 and the lower horizontal wire 6 are accurately aligned on the welding surface. After clamping, the welding machine 17 welds them together, and the three layers of material are combined into one in the welding area. After the welding clamping device is released, the material can continue to move forward with the annular guide rail slider.

[0051] The welding device 17, finished coil 15, upper horizontal wire 4 coil, lower horizontal wire 6 coil and other structures are all supported by the frame 14.

[0052] In this invention, the operation of each power component is basically controlled by the control system, thus achieving automation.
