Description

Technical Field

[0001] This invention relates to the field of metal wire mesh welding tools, and in particular to an intelligent laser welding device for manufacturing metal wire mesh. Background Technology

[0002] Metal wire mesh is a key component in precision filtration, electronic devices, security protection, building support, and animal husbandry. The quality of its welding directly determines its performance and service life. As a new type of forming equipment to replace traditional resistance welding, metal wire mesh laser welding equipment relies on laser non-contact fusion welding to connect the wire intersections. It has the advantages of small thermal deformation, beautiful welds, and no mechanical extrusion damage. It is widely used in automated production lines for fine-diameter wire mesh and precision filter mesh. The existing metal wire mesh laser welding equipment mainly consists of a welding base, a simple wire feeding roller frame, a fixed welding frame, a laser welding head, a support platform, and a traction feeding mechanism. Its conventional operation process is as follows: the metal wires are placed on the wire feeding roller frame, and the traction device pulls the horizontal and vertical wires into the welding station. After the wires fall to the support platform, they are initially positioned by simple pressure blocks or mechanical limits. The welding frame drives the laser welding head down to weld the intersection of the horizontal and vertical wires point by point. The formed wire mesh is discharged manually or by a simple conveyor belt, completing the batch welding production. In the actual continuous production process, the simple wire feeding roller frame and passive traction feeding method of existing metal wire mesh laser welding equipment cause multiple longitudinal wires to come into close contact with each other and intersect irregularly during the conveying process, resulting in entanglement and knotting. This leads to poor wire feeding, potential downtime, and problems such as easy wire entanglement and inconsistent finished product quality in metal wire mesh laser welding equipment. To address these issues, this application designs an intelligent laser welding equipment for metal wire mesh manufacturing. Summary of the Invention

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Example 1: See Figures 1 to 14The present invention discloses an intelligent laser welding device for manufacturing metal wire mesh, comprising a laser welding base 1, a material discharge conveyor 2 placed on the side of the laser welding base 1, and a welding frame 3 slidably mounted on the laser welding base 1. A sliding conveyor 7 for lifting and pushing the metal wire mesh is slidably mounted on the material discharge conveyor 2. Multiple welding support seats 13, adapted to the spacing of the horizontal wires of the metal wire mesh, are equidistantly mounted on the laser welding base 1 at the lower end of the welding frame 3. Each welding support seat 13 has a limiting support groove 17 for supporting the horizontal wires of the metal wire mesh. Auxiliary pneumatic grippers 16 for clamping the vertical wires of the metal wire mesh are symmetrically mounted at both ends of the laser welding base 1. A material conveying mechanism for cooperating with each welding support seat 13 to convey the horizontal wires of the metal wire mesh is mounted on one side of the laser welding base 1. The laser welding base 1 has multiple welding support seats 13 on both sides of the laser welding base 1. A hydraulic adjustment seat 11 for raising and lowering the welding frame 3 is installed on the wall. Laser welding guns 15 for welding horizontal and vertical metal wire mesh are installed at intervals at the lower end of the welding frame 3. An intelligent adjustment control box is installed in the laser welding seat 1. Two support seats 18 are symmetrically installed on the side wall of the laser welding seat 1. A longitudinal feed seat 6 is installed on the support seat 18, and a feeding and conveying mechanism for the longitudinal wire mesh is installed on the longitudinal feed seat 6. The laser welding seat 1 serves as the load-bearing base of the entire machine, ensuring the stability of the welding operation. The discharge conveyor 2, in conjunction with the sliding conveyor 7, enables automatic sliding discharge of the wire mesh after welding. The welding support seat 13 and the limiting support groove 17 can accurately position and support the horizontal wire mesh, and the auxiliary pneumatic gripper 16 clamps and fixes the longitudinal wire, avoiding... During the welding-free process, wire deviation is prevented. The hydraulic adjustment seat 11 can raise and lower the welding frame 3 to adjust the welding parameters for different thicknesses of wire mesh. The laser welding gun 15 enables multi-point synchronous welding. Simultaneously, the longitudinal feed seat 6 and the unloading conveyor mechanism are mounted on the support seat 18 to achieve automatic feeding of the longitudinal wire mesh. This, combined with the horizontal guide structure, completes the precise docking of the longitudinal and horizontal wires, effectively improving the automation level and welding accuracy of wire mesh welding. The unloading conveyor mechanism includes a motor rod 20 rotatably mounted on the longitudinal feed seat 6, a wire feeding assembly mounted on one side of the longitudinal feed seat 6 on the motor rod 20, and a wire guiding conveyor assembly mounted on the other side of the longitudinal feed seat 6 on the motor rod 20. A shock-absorbing support is installed between the longitudinal feed seat 6 and the support seat 18 to support the longitudinal feed seat 6. The protective support pad 19 and the longitudinal feed seat 6 are bolted and fixed to the support support seat 18. The inner wall of the longitudinal feed seat 6 is fixedly embedded with a rotary motor for driving the motor rod 20 to rotate. The motor rod 20 is equipped with support rollers 32 for supporting and conveying the longitudinal wire mesh. Multiple transmission rollers 33 for picking up and feeding the longitudinal wire mesh are symmetrically installed on the motor rod 20. The protective support pad 19 can effectively buffer the vibration of the equipment operation and avoid the longitudinal feed seat 6 from shaking and causing the wire feeding to deviate. The rotary motor drives the motor rod 20 to rotate stably. The support rollers 32 support and convey the longitudinal wire mesh smoothly. The transmission rollers 33 cooperate with the wire feeding component and the wire sorting and transmission component to realize continuous material picking and feeding, ensuring that the longitudinal wire mesh is conveyed continuously, smoothly and without jamming.

[0019] Example 2: The technical solution is basically the same as that of Example 1, except that, as Figures 6 to 10 As shown, multiple picking blocks 42 are circumferentially equidistantly installed on the transmission wheel 33. The picking blocks 42 are bolted to the transmission wheel 33, and have slots on them for engaging with the wire mesh longitudinal wires for rotational transmission. The picking blocks 42 can stably engage with the wire mesh longitudinal wires through the slots, achieving fixed-point picking and quantitative feeding, avoiding wire slippage and misalignment. The bolted structure facilitates disassembly and replacement later, and can be adapted to clamping and conveying wire mesh longitudinal wires of different diameters, improving the equipment's versatility and feeding accuracy. The wire feeding assembly includes a connecting support frame 23 fixedly installed on the top of the longitudinal wire feed seat 6, a sliding... A longitudinal wire limiting frame 21 is movably installed at the lower end of the connecting support frame 23, and a combined support frame is installed between the longitudinal wire feed seat 6. A wire feeding groove for longitudinal wire mesh is formed between the longitudinal wire limiting frame 21 and the combined support frame. An adjusting electric push rod 24 is installed in the middle of the connecting support frame 23, and the other end of the adjusting electric push rod 24 is fixedly connected to the longitudinal wire limiting frame 21. Multiple guide sleeves 25 are slidably inserted between the longitudinal wire limiting frame 21 and the connecting support frame 23. A conveyor belt 43 for pushing the longitudinal wire mesh is installed on the lower end face of the longitudinal wire limiting frame 21. The transmission motor housing 22 is equipped with a drive motor box 22 for rotating the conveyor belt 43; the adjustable electric push rod 24 can drive the longitudinal wire limit frame 21 to slide vertically and adjust, precisely controlling the spacing of the wire feeding chute, adapting to the feeding of wire mesh of different thicknesses; the guide sleeve 25 ensures that the longitudinal wire limit frame slides smoothly without deviation; the transmission motor housing 22 drives the conveyor belt 43 to actively push the wire down, and works with the combined support frame to achieve limited and guided feeding, effectively preventing wire stacking, knotting, and deviation, and ensuring a stable and orderly feeding process; the combined support frame includes an adjusting mounting plate 34 fixedly installed between the longitudinal wire feed seats 6, the adjusting mounting plate Multiple limiting and fixing sleeves 35 are installed on the adjusting mounting plate 34 with spaced bolts. The first feeding guide plate 36 is snapped and fixed on the limiting and fixing sleeve 35 in the middle of the adjusting mounting plate 34, and the second feeding guide plate 37 is snapped and fixed on the limiting and fixing sleeves 35 at both ends of the adjusting mounting plate 34. The adjusting mounting plate 34 provides a stable mounting base for the guide plate structure. The limiting and fixing sleeves 35 are fixed by snap-fit ​​bolts, which facilitates quick disassembly and assembly of the first feeding guide plate 36 and the second feeding guide plate 37 and adjustment of the spacing. The guiding layout can be flexibly adjusted according to the wire mesh specifications to realize synchronous and zoned guiding feeding of multiple metal wire mesh longitudinal lines and improve the feeding regularity.

[0020] Example 3: The technical solution is basically the same as that of Example 1, except that, as Figures 7 to 14As shown, multiple first guide rollers 38 for conveying the longitudinal wire mesh are rotatably mounted at intervals on the first feeding guide plate 36. Sliding plates 39 are slidably mounted on both sides of the second feeding guide plate 37. Multiple spring telescopic rods 41 are symmetrically mounted laterally at both ends of each sliding plate 39. Multiple second guide rollers 40 are equidistantly mounted on the sliding plate 39, rotating at an angle. The second guide rollers 40 on the two sliding plates 39 are symmetrically distributed in a figure-eight shape. The first guide rollers 38 provide straight and stable conveying of the central longitudinal wire, while the figure-eight-shaped second guide rollers 40 can adaptively straighten the wire and, through sliding... Plate 39 and spring telescopic rod 41 slide slightly to adapt to each other, avoiding excessive stress and stretching of the wire mesh longitudinal lines, which would cause deformation of the wire mesh longitudinal lines; the wire conveying assembly includes a fixed mounting base 29 installed between the longitudinal line feed seats 6 and four mounting connecting plates 26 installed at both ends of the longitudinal line feed seats 6. Multiple support plates 30 for supporting the wire mesh longitudinal lines are installed at equal intervals and at an angle on the fixed mounting base 29. A grid plate 27 is installed between the two sets of mounting connecting plates 26. The lower end of the grid plate 27 is connected to a guide limiting plate 46 that cooperates with the support plates 30 to limit the wire mesh longitudinal lines; the support plates 30 support multiple wire The longitudinal wires are supported in sections. The grid plate 27 and the guide limiting plate 46 cooperate to form a layered limiting channel, which can initially separate and limit the longitudinal wires during conveying, preventing multiple wires from tangling and overlapping, and ensuring the orderly progress of subsequent combing and welding processes. An installation adjustment block 31 is installed at the end of the mounting plate 26. A wire management channel is separated between the grid plate 27 and the installation adjustment block 31. An electric telescopic partition 44 for increasing the wire management channel is installed on the installation adjustment block 31. A linear motor sliding seat 28 is slidably installed on one side of the grid plate 27. The linear motor sliding seat 28 has spaced protrusions for matching metal. A combing separator 45 with varying wire mesh thickness extends through the gaps in the grid plate 27. An electrically operated telescopic separator 44 automatically adjusts the width of the wire routing channel according to the wire specifications and separates the wire mesh longitudinals on both sides, preventing a large number of wire mesh longitudinals from crowding and affecting the normal operation of the wire routing. It is adaptable to wire mesh longitudinals of different thicknesses. A linear motor sliding seat 28 drives the combing separator 45 to slide back and forth, dynamically separating and combing multiple longitudinals at equal intervals, eliminating wire crossing and overlapping problems, and ensuring that the spacing between each wire mesh longitudinal is uniform and the posture is regular, providing a prerequisite for high-precision laser welding.

[0021] Example 4: The technical solution is basically the same as that of Example 1, except that, as Figures 1 to 5As shown, the conveying and guiding mechanism includes a horizontal wire guide frame 4 for guiding and separating the horizontal wire mesh, symmetrically mounted limiting and conveying adjustment plates 5 on both sides of the laser welding base 1, fixed rollers 8 rotatably mounted between the two limiting and conveying adjustment plates 5, and two movable rollers 9 slidably mounted on the limiting and conveying adjustment plates 5. An adjusting knob 10 for adjusting the sliding height of the movable rollers 9 is rotatably mounted on the limiting and conveying adjustment plates 5. The end of the adjusting knob 10 is rotatably engaged with a limiting support sleeve for fitting the movable rollers 9, and the limiting support sleeve is slidably engaged with the limiting and conveying adjustment plates 5. The horizontal wire guide frame 4 can guide and separate the horizontal wire mesh. The fixed rollers 8 and the movable rollers 9 cooperate to achieve horizontal wire clamping and conveying. The adjusting knob 10 can adjust the height of the movable rollers 9 through the limiting support sleeve, flexibly adapting to the conveying of horizontal wire mesh of different thicknesses and specifications, ensuring... The horizontal wire conveyor is designed to ensure uniform tension and smooth transport, preventing slackness and arching that could affect the accuracy of welding points. Two mounting rails 12 are installed at intervals on the laser welding seat 1 on one side of the welding support 13. Multiple abutment limiting plates 14, located between the welding support 13, are bolted to the two mounting rails 12. One end of the abutment limiting plate 14 is inclined at the welding point, forming a limiting angle with the supporting end face of the welding support 13 to limit the contact with the longitudinal wire of the metal mesh. The mounting rails 12 facilitate flexible disassembly and fine-tuning of the abutment limiting plates 14. The abutment limiting plates 14 and the welding support 13 cooperate to form a limiting angle, allowing for precise contact and limiting of the longitudinal wire at the welding point. This effectively restricts deviation and warping during welding, ensuring tight fit at the intersection points of the horizontal and vertical wires, significantly improving the quality of laser welding and the overall flatness of the wire mesh.

[0022] Working principle: In this embodiment, the present invention also proposes a method for using an intelligent laser welding device for manufacturing metal wire mesh, including the following steps: Step 1: When this intelligent laser welding equipment for metal wire mesh manufacturing is working, the entire machine uses the laser welding base 1 as the supporting base. After the equipment is powered on and started, all mechanisms work together to complete the entire process of automatic feeding, precise alignment, limit clamping, laser welding, and automatic unloading of the horizontal and vertical wire mesh. In the early stage of operation, the horizontal wire mesh is directionally conveyed by the conveying and guiding mechanism on one side of the laser welding base 1. The horizontal wire guide frame 4 guides and separates the horizontal wire. The fixed roller 8 and the movable roller 9 between the limit transmission adjustment plates 5 cooperate to clamp and convey the horizontal wire. The operator adjusts the installation height of the movable roller 9 by adjusting the knob 10 to drive the limit support sleeve to slide, adapting to the horizontal wire mesh of different thicknesses and specifications, ensuring that the horizontal wire is conveyed with uniform tension and stable conveying, and avoiding the horizontal wire from slack and arching, which would cause the welding point to shift. After being conveyed, the horizontal wire mesh falls precisely into the limit support groove 17 of each welding support 13, completing the positioning and placement of the horizontal wire. Step two, simultaneously, the support seats 18 on both sides of the laser welding seat 1 stably support the longitudinal feed seat 6, and the protective support pad 19 between the two plays a shock absorption and buffering role, effectively offsetting the vibration of the equipment operation and preventing the longitudinal feeding mechanism from shaking and deviating; the rotating motor drive motor rod 20 inside the longitudinal feed seat 6 rotates continuously, driving the support wheel 32 and the transmission wheel 33 to operate synchronously, and the picking block 42 arranged circumferentially on the transmission wheel 33 stably engages the metal wire mesh longitudinal line through the end slot, realizing fixed-point and quantitative continuous picking and conveying. The bolt-installed picking block 42 can be adapted to wires of different diameters and has strong versatility; Step 3: During the longitudinal conveying process, the wire feeding assembly works synchronously. The electric push rod 24 drives the longitudinal limit frame 21 to slide vertically along the guide sleeve 25, precisely controlling the opening and closing distance of the wire feeding chute to adapt to the longitudinal wires of different thicknesses. The transmission motor box 22 drives the lower transmission belt 43 to actively push the wires down, and works with the combined support frame to complete the limiting and guiding feeding. The adjusting mounting plate 34 fixes the first feeding guide plate 36 and the second feeding guide plate 37 respectively through the limiting fixing sleeve 35. The first feeding transmission roller 38 on the first feeding guide plate 36 smoothly and linearly conveys the middle longitudinal wire. The sliding plate 39 on the second feeding guide plate 37, together with the spring telescopic rod 41, adaptively and finely adjusts the position. The second feeding transmission roller 40, distributed in a figure-eight shape, can flexibly straighten the wires to avoid excessive stretching and deformation of the wires and ensure the regularity of the feeding. Step four: Subsequently, after the wire is fed into the wire sorting and transmission assembly, the inclined support plate 30 on the fixed mounting base 29 supports multiple sets of longitudinal wires in sections, forming a layered limiting channel with the grid plate 27 and the guide limiting plate 46, initially preventing the wires from overlapping and stacking. During operation, the electric telescopic partition 44 on the mounting adjustment block 31 can adjust the width of the wire sorting channel according to the wire specifications to alleviate wire compression and congestion. At the same time, the linear motor sliding base 28 on one side of the grid plate 27 drives the combing partition plate 45 to slide back and forth, dynamically sorting and dividing multiple metal wire mesh longitudinal wires at equal intervals, completely eliminating the problem of wire overlap and tangling, and ensuring that each longitudinal wire is neat and uniform in posture and spacing. Step five, finally, the combed metal wire mesh longitudinal lines are conveyed to the welding station. The auxiliary pneumatic grippers 16 at both ends of the laser welding seat 1 clamp and fix the two ends of the longitudinal lines, forming a limiting angle with the abutment limiting plate 14 between the welding support seats 13, precisely limiting the longitudinal line offset and tilting, and ensuring that the intersection points of the longitudinal and transverse lines are tightly fitted. Then, the hydraulic adjustment seats 11 on both sides adjust the lifting height of the welding frame 3 to match the current wire mesh welding parameters. The multiple sets of laser welding guns 15 at the lower end of the welding frame 3 are started simultaneously to perform multi-point laser welding operations on the intersection points of the longitudinal and transverse lines. After welding is completed, the finished wire mesh falls above the discharge conveyor table 2, and is lifted and slid by the sliding conveyor table 7 to complete the automatic discharge. The whole process has a high degree of automation and the welding accuracy and production efficiency are greatly improved.
