Description
Technical Field
[0001] This invention relates to the field of mesh chain welding technology, specifically to a mesh chain welding machine. Background Technology
[0002] like Figures 1-2 As shown, existing mesh belt products typically consist of multiple parallel steel bars connected by spiral wires to form a mesh structure. L-shaped plates are installed at both ends of the steel bars, with insertion holes on the L-shaped plates. The ends of the steel bars pass through these holes and are then welded to the L-shaped plates for fixation. This type of product is widely used in conveying equipment, filtration devices, and heat treatment furnace mesh belts, and its welding quality directly affects the strength, flatness, and overall performance of the mesh belt.
[0003] Currently, the welding of most mesh chain products still relies on manual operation: workers need to manually position the steel bars and L-shaped plates and then spot weld them. This not only results in low welding efficiency, but also makes it difficult to guarantee the consistency of the welding points and the uniformity of the penetration depth due to human operation, which easily leads to quality problems such as incomplete welding and burn-through.
[0004] Therefore, a mesh chain welding machine is proposed. Summary of the Invention

[0037] Compared with the prior art, the beneficial effects of the present invention are:
[0038] By incorporating a conveying mechanism, welding robot, palletizing mechanism, pressing mechanism, correction mechanism, and material turning mechanism, rapid welding of mesh chain products is achieved, reducing manual operation and improving production efficiency and product consistency.
[0039] The first support seat of the conveying mechanism can adjust the spacing according to the specifications of the mesh chain product through the first spacing adjustment mechanism. Combined with the sliding connection design between the external spline shaft and the sprocket, the support mechanism can be adapted to mesh chain products of different sizes, improving the versatility of the equipment.
[0040] The positioning pins and tensioning pins of the support components are prevented from shifting during the conveying process by cooperating with the sliding block through the spring. Combined with the tensioning push plate driven by the first linear module, the mesh chain product can be automatically tensioned at the welding position, providing a stable foundation for welding.
[0041] The correction mechanism drives the lifting frame through an electric cylinder, and adjusts the spacing of the correction units in conjunction with the second spacing adjustment mechanism. It uses a linear module and gear rack transmission to drive the flipping plate to rotate, which can accurately adjust the tilted L-shaped plate to a vertical state, ensuring the correct posture of the workpiece during welding and avoiding welding defects caused by angular deviation.
[0042] The upper and lower clamping units of the clamping mechanism drive the clamping plates through cylinders, simultaneously clamping the mesh chain product at the welding position from both the upper and lower ends to form a rigid fixation, effectively preventing workpiece vibration or displacement during the welding process, and improving welding accuracy and finished product qualification rate.
[0043] The palletizing mechanism uses the X, Y, and Z axis drive mechanism to achieve three-dimensional spatial movement of the clamping mechanism, which can accurately grab the welded mesh chain products and stack them on the palletizing plate in an alternating forward and reverse manner to meet the requirements of orderly stacking and improve warehousing efficiency.
[0044] The material turning mechanism uses a cylinder to drive a rack and pinion transmission to achieve a 180° rotation of the support frame. In conjunction with the receiving rack and cylinder action of the transfer component, it can automatically turn the wire mesh products without manual intervention, ensuring that the products are arranged alternately in the forward and reverse directions during palletizing, and adapting to different packaging and transportation requirements.
[0045] The mesh chain auxiliary assembly mechanism at the feeding position uses a cylinder to drive the lifting seat, which enables the limiting groove of the steel bar limiting seat to accurately position the steel bar of the mesh chain product. This assists in inserting the L-shaped plate into the end of the steel bar, reducing the difficulty of manual alignment and improving feeding efficiency and assembly accuracy.

[0101] The two sprockets 1054 at both ends of the first support base 102 are connected by a chain drive. Eight sets of support mechanisms for supporting the mesh chain product 8 are equidistantly arranged on the chain plate. The support mechanism includes two sets of support components 104. One set of support components 104 is set on one chain, and the other set of support components 104 is set on the other chain. Both sets of support components 104 include support plates 1041. Multiple support plates 1041 are arranged linearly. The support plates 1041 are fixedly installed on the chain plate. One end of the support component 104 is fixedly connected to a positioning pin 1042, and the other end of the support component 104 is slidably provided with a tensioning pin 1043. The limiting pin hole 805 at one end of the mesh chain product 8 is sleeved on the positioning pin 1042, and the limiting pin hole 805 at the other end of the mesh chain product 8 is sleeved on the tensioning pin 1043.
[0102] In operation, the conveying mechanism 1 first transports the mesh chain product 8 from its initial position to various processing positions. In the structure of the conveying mechanism 1, the first base 101 supports the entire conveying structure. Two first support seats 102 are mounted on the first base 101 via a first spacing adjustment mechanism 103, allowing for spacing adjustment according to the different specifications of the mesh chain product 8. The external spline shafts 1052 at both ends of the first support seats 102 are slidably connected to the sprockets 1054 via internal splines, and the external spline shafts 1052 are connected to the second motor 105 via a worm gearbox 1051. After the second motor 105 starts, it drives the worm inside the worm gearbox 1051 to rotate, which in turn causes the worm wheel to rotate, driving the external spline shaft 1052 to rotate, thereby causing the sprocket 1054 to rotate. The rotation of sprocket 1054 drives the chain to move, and the support mechanism on the chain moves accordingly. When adjusting the distance between the two first support seats 102, the lower end of the limiting pin 1022 extends into the groove of the pulley 1055, and the limiting pin 1022 slides in contact with the inner wall of the groove of the pulley 1055. Therefore, when the first support seat 102 moves, it will drive the sprocket 1054 to move together. The support mechanism includes two sets of support components 104. The support plate 1041 in the support component 104 is fixed to the chain plate and plays the role of supporting the mesh chain product 8.
[0103] Furthermore, a waist hole 1044 is provided on the support plate 1041 near the tension pin 1043 of the support assembly 104. A sliding block 1045 is slidably installed inside the waist hole 1044. The tension pin 1043 is fixed to the top of the sliding block 1045. A spring 1046 is provided at both ends of the sliding block 1045. One end of the spring 1046 abuts against the inner wall of the waist hole 1044, and the other end of the spring 1046 abuts against the end of the sliding block 1045.
[0104] A first linear module 9 is fixedly installed on the first base 101. A tensioning push plate 901 is fixedly installed on the slide of the first linear module 9. The first linear module 9 is located on the side of the welding position. During welding, the first linear module 9 drives the tensioning push plate 901 to move, so that the tensioning push plate 901 pushes the lower end of the sliding block 1045 to move away from the positioning pin 1042, thus tensioning the mesh chain product 8.
[0105] During use, because the L-shaped plate 802 has limiting pin holes 805, the limiting pin hole 805 at one end of the mesh chain product 8 is fitted onto the positioning pin 1042, and the limiting pin hole 805 at the other end is fitted onto the tensioning pin 1043, thus positioning the mesh chain product 8. When the mesh chain product 8 is conveyed to the side of the welding position, the first linear module 9 drives the tensioning push plate 901 to move, pushing the sliding block 1045 to overcome the elastic force of the spring 1046 and move away from the positioning pin 1042, thus tensioning the mesh chain product 8 for subsequent welding operations.
[0106] Once the mesh chain product 8 is transported to the welding station, two welding robots 2 positioned on either side of the welding station begin operation. Following a pre-set program and path, the welding robots 2 weld the ends of the steel bars 801 in the mesh chain product 8 to the L-shaped plate 802. The welding robots 2 can precisely control the welding position, angle, and welding parameters, ensuring the stability and consistency of the welding quality.
[0107] In this embodiment, the first spacing adjustment mechanism 103 includes a first motor 1031 and a first lead screw 1032. The threads at both ends of the first lead screw 1032 have opposite directions of rotation. Both ends of the first lead screw 1032 are threadedly mounted with first movable seats 1035. The first movable seats 1035 are respectively fixed to the bottom of the corresponding first support seats 102. The first lead screw 1032 is rotatably mounted on the first base 101 through a first bearing 1036. The first motor 1031 is fixed on the first base 101. A first synchronous gear 1033 is fixedly sleeved on the first lead screw 1032. A second synchronous gear is fixedly connected to the shaft of the first motor 1031. The first synchronous gear 1033 and the second synchronous gear are connected by a first synchronous toothed belt 1034. A first slide rail 1037 is fixedly connected to the first base 101. A first slider 1038 is fixedly connected to the bottom of each of the two first support seats 102. The first slider 1038 is slidably mounted on the first slide rail 1037.
[0108] In use, the first motor 1031 starts, driving the second synchronous gear to rotate. The first synchronous gear 1033 rotates through the first synchronous belt 1034, which in turn drives the first lead screw 1032 to rotate. Since the threads at both ends of the first lead screw 1032 turn in opposite directions, the first movable seats 1035, which are rotatably mounted at both ends, move closer or further apart, thereby adjusting the distance between the two first support seats 102.
[0109] In this embodiment, the pressing mechanism 4 includes an upper pressing unit 404 and a lower pressing unit 405. The lower pressing unit 405 is disposed below the support assembly 104, and the upper pressing unit 404 is disposed above the support assembly 104.

[0111] The lower clamping unit 405 includes a lower fixing frame 4051. The bottom of the lower fixing frame 4051 is fixed on the first base 101. A lower clamping cylinder 4052 is fixedly connected to the top of the lower fixing frame 4051. A lower clamping plate 4053 is fixedly installed on the top of the piston rod of the lower clamping cylinder 4052.
[0112] During the welding process, the clamping mechanism 4 clamps and positions the mesh chain product 8 at the welding position. Specifically, the upper clamping cylinder 4042 is activated, its piston rod extends, and it moves the upper clamping plate 4043 downwards, clamping the upper part of the mesh chain product 8. Simultaneously, the lower clamping cylinder 4052 is activated, its piston rod extends, and it moves the lower clamping plate 4053 upwards, clamping the lower part of the mesh chain product 8. This simultaneous clamping from both above and below ensures that the mesh chain product 8 does not shift during welding, guaranteeing welding accuracy.
[0113] In this embodiment, the correction mechanism includes a second support frame 401 and a lifting frame 403. The second support frame 401 is fixedly mounted above the welding position. An electric cylinder 402 is fixedly installed on the top of the second support frame 401. The bottom of the piston rod of the electric cylinder 402 is fixedly connected to the top of the lifting frame 403. The lifting frame 403 is movably disposed inside the second support frame 401. Correction units 407 are provided on both sides of the lower end of the lifting frame 403. Two sets of correction units 407 are installed at the lower end of the lifting frame 403 through a second spacing adjustment mechanism 406.
[0114] The second spacing adjustment mechanism 406 includes a third motor 4061 and a second lead screw 4062. The third motor 4061 is fixed on the lifting frame 403. The second lead screw 4062 is rotatably installed on the lower end of the lifting frame 403 through a second bearing seat. The threads at both ends of the second lead screw 4062 are opposite in direction. Both ends of the second lead screw 4062 are threadedly rotatably connected to a second movable seat 4063. The bottom of both second movable seats 4063 is fixedly connected to an adjustment support plate 4064. The bottom of the lifting frame 403 is fixedly connected to a third slide rail 4065. The top of the adjustment support plate 4064 is fixedly connected to a third slider 4066. The third slider 4066 is slidably installed on the third slide rail 4065.
[0115] The correction unit 407 includes a second linear module 4071 and a rotating shaft 4076. The adjusting support plate 4064 is arranged in an inverted U-shape. The rotating shaft 4076 is rotatably mounted on the inner side of the lower end of the adjusting support plate 4064 via bearings. The second linear module 4071 is fixed to the bottom of the adjusting support plate 4064. A movable seat 4074 is fixedly connected to the bottom of the slide of the second linear module 4071. A first rack 4075 is fixedly connected to the bottom of the movable seat 4074. A first gear 4 is fixedly sleeved on the rotating shaft 4076. 077, the first gear 4077 meshes with the first rack 4075, a fixed connecting block 40761 is fixedly connected to the rotating shaft 4076, a flipping plate 4078 is fixedly connected to the bottom of the fixed connecting block 40761, a first cylinder 4079 is fixedly installed at the bottom of the flipping plate 4078, a first correcting plate 40791 is fixedly connected to the piston rod end of the first cylinder 4079, and a second correcting plate 40792 is fixedly connected to the end of the cylinder body of the first cylinder 4079 away from the first correcting plate 40791.
[0116] The bottom of the adjusting support plate 4064 is fixedly connected to the fourth slide rail 4072, and the top of the movable seat 4074 is fixedly connected to the fourth slider 4073. The fourth slider 4073 is slidably mounted on the fourth slide rail 4072.
[0117] The upper fixing frame 4041 is fixed to the bottom of the lifting frame 403.
[0118] Before welding, the correction mechanism corrects the L-shaped plates 802 at both ends of the mesh chain product 8, changing them from an inclined state to a vertical state. Specifically, the third motor 4061 is controlled to rotate, which in turn drives the second lead screw 4062 to rotate. Because the threads at both ends of the second lead screw 4062 rotate in opposite directions, and both ends are threadedly mounted with second movable seats 4063, the rotating second lead screw 4062 can drive the second movable seats 4063 at both ends to move towards or away from each other, thereby adjusting the distance between the two adjusting support plates 4064. This allows the spacing between the two correction units 407 to be adjusted according to the size of the mesh chain product 8. Then, the piston rod of the electric cylinder 402 is controlled to extend, thereby moving the lifting frame 403 downwards, so that the upper end of the L-shaped plate 802 is positioned between the first correction plate 40791 and the second correction plate 40792. Then, the piston rod of the first cylinder 4079 is controlled to retract, thereby driving the first correcting plate 40791 to move towards the second correcting plate 40792, thus clamping the upper end of the L-shaped plate 802. Then, the slide of the second linear module 4071 is controlled to move, and the moving slide drives the first rack 4075 to move, thereby driving the first gear 4077 meshing with it to rotate. The rotating first gear 4077 drives the rotating shaft 4076 to rotate, and the rotating shaft 4076 drives the flipping plate 4078 fixedly connected to it to rotate, thereby driving the first correcting plate 40791 and the second correcting plate 40792 to rotate, so that the angle of the L-shaped plate 802 can be adjusted to make it vertical.
[0119] The correction unit 407 further includes a controller and an angle sensor, wherein the controller is configured as follows:
[0120] (a) Obtain the tilt angle θ of the L-shaped plate 802 using an angle sensor;
[0121] (b) Calculate the moving distance Δs of the second linear module 4071 according to the compensation equation;
[0122] (c) Control the second linear module 4071 to move Δs, and drive the flip plate 4078 to rotate to correct the L-shaped plate.
[0123] The compensation equation is expressed as follows:
[0124]
[0125] Parameter description:
[0126] Δs: The moving distance of the slide of the second linear module 4071 (unit: mm);
[0127] θ: Initial tilt angle of L-shaped plate 802 (unit: radians);
[0128] d g : Pitch circle diameter of the first gear 4077 (unit: mm);
[0129] c: Deformation compensation coefficient (unit: 1 / radian), calibrated experimentally (typical value range: 0.02–0.1).
[0130] Example:
[0131] 1. Detect tilt angle: The angle sensor measures the initial tilt angle of the L-shaped plate θ = 0.1 rad (approximately 5.7°).
[0132] 2. Parameter substitution: Take d g =20mm, c=0.05rad −1 Substitute into the equation:
[0133]
[0134] 3. Execution control: The second linear module moves Δs=1.005mm, driving the flip plate 4078 to rotate and correct the angle.
[0135] Technical effects of the solution
[0136] Improved precision: Compensates for nonlinear errors caused by mechanism gaps and material elasticity, and the vertical deviation of the L-shaped plate is ≤0.2° after correction.
[0137] Efficiency optimization: Avoid repeated adjustments and significantly reduce the time required for a single correction.
[0138] Enhanced reliability: Prevents plate deformation or mechanism overload caused by over-correction.
[0139] Working principle and process
[0140] 1. Testing phase:
[0141] The lifting frame 403 descends, and the first correction plate 40791 and the second correction plate 40792 clamp the upper end of the L-shaped plate 802.
[0142] An angle sensor measures the tilt angle θ in real time.
[0143] 2. Calculation stage:
[0144] The controller calculates Δs and the diameter d of the fusion gear based on the equation.g And the compensation coefficient c determined by the experiment.
[0145] 3. Execution Phase:
[0146] The second linear module 4071 moves by Δs, and through the transmission of the first rack 4075 and the first gear 4077, drives the flip plate 4078 to rotate.
[0147] The L-shaped plate was precisely adjusted to a vertical position (θ≈0).
[0148] 4. Welding stage:
[0149] The clamping mechanism 4 fixes the workpiece, and the welding robot 2 completes the welding.
[0150] The compensation equation is deeply coupled with the gear and rack transmission of the correction mechanism (d) g ) and material deformation properties (c); quadratic term θ 2 To address the elastic deformation error observed in experiments, this paper aims to solve the problem of insufficient accuracy of linear models in existing technologies. The coefficient c needs to be optimized through experiments for different network chain products to reflect customized design and significantly improve correction accuracy and efficiency.

[0156] After welding is completed, the palletizing mechanism 3 places the welded mesh chain products 8 on the palletizing plate 6 in an alternating forward and reverse manner.
[0157] In operation, the X-axis drive motor 3021 starts, driving the transmission rod 3022 to rotate, causing the X-axis transmission gears 3024 at both ends to rotate and mesh with the X-axis rack 3023, thus allowing the X-axis beam 302 to slide on the X-axis slide rail 3025. The Y-axis drive mechanism is mounted on the X-axis beam 302.

Through the coordinated movement of the X, Y, and Z axes, the clamping mechanism can accurately reach above the welded mesh chain product 8. The clamping motor 305 of the clamping mechanism starts, driving the connecting shaft to rotate, which in turn causes the second synchronous gear 3051 to rotate. This, in turn, drives the first gripper 3055 to slide on the second slide rail 3053 via the second synchronous toothed belt 3052, engaging with the second gripper 3056 to clamp the mesh chain product 8. Then, it is moved to the palletizing plate 6 for stacking.
[0158] In this embodiment, the material turning mechanism 5 includes a third support frame 501, which is disposed on one side of the unloading position. A material turning component 502 is disposed on the third support frame 501. The material turning component 502 includes a support column 5021 and a support frame 5022. The support column 5021 is fixed on the third support frame 501. There are two support columns 5021. Rotating rods 5023 are fixedly installed at both ends of the support frame 5022. The support frame 5022 is disposed between the two support columns 5021. The rotating rods 5023 are rotatably mounted on their corresponding support columns 5021 through a third bearing seat. A second cylinder 5024 is fixedly installed on one side of one of the support columns 5021. A second rack 5025 is fixedly installed on the top of the piston rod of the second cylinder 5024. A second gear 5026 is fixedly sleeved on one of the rotating rods 5023. The second gear 5026 meshes with the second rack 5025.
[0159] A third cylinder 5027 is fixedly installed at both ends of the support frame 5022. A fourth cylinder 5028 is fixedly installed at the end of the piston rod of the third cylinder 5027. A clamping rod 5029 is fixedly installed at the top of the piston rod of the fourth cylinder 5028.
[0160] A transfer assembly 503 is provided on the third support frame 501. The transfer assembly 503 includes a fourth support frame 5031, which is fixed to the third support frame 501. Fifth slide rails 5034 are fixedly installed on the top of both sides of the fourth support frame 5031. Fifth sliders 5035 are slidably installed on the fifth slide rails 5034. A transfer seat 5033 is fixedly installed on the fifth slider 5035. A fifth cylinder 5036 is fixedly installed at the bottom of the transfer seat 5033. The piston of the fifth cylinder 5036... After the top of the rod slides through the transfer seat 5033, a receiving frame 5037 is fixedly installed. A fourth motor 5032 is fixedly installed on the fourth support frame 5031.

The bottom of the transfer seat 5033 is fixedly connected to the third synchronous toothed belt 50321.
[0161] In use, when the welded mesh chain product 8 needs to be flipped, the stacking mechanism 3 first moves the welded mesh chain product 8 onto the support frame 5022, then releases it. Then, it controls the piston rod of the third cylinder 5027 to retract, thereby driving the fourth cylinder 5028 to move closer to the center of the support frame 5022. This causes the clamping rod 5029 to move above the L-shaped plate 802 at the end of the mesh chain product 8. Then, it controls the piston rod of the fourth cylinder 5028 to retract, thereby clamping... The tension rod 5029 presses against the lower end of the L-shaped plate 802 to fix the mesh chain product 8. Then, the piston rod of the second cylinder 5024 is extended, which drives the second rack 5025 to move upward. The upward movement of the second rack 5025 drives the second gear 5026 to rotate. The rotating second gear 5026 drives the support frame 5022 to rotate through the rotating rod 5023, thereby rotating the mesh chain product 8 fixed on the support frame 5022. When the mesh chain product 8 rotates 180°, the control... The shaft of the fourth motor 5032 rotates, which in turn drives the third synchronous toothed belt 50321 to rotate. The rotating third synchronous toothed belt 50321 drives the transfer seat 5033 to move towards the mesh chain product 8. When the transfer seat 5033 moves directly under the mesh chain product 8, the piston rod of the fifth cylinder 5036 is extended, causing the receiving frame 5037 to abut against the steel bar 801 of the mesh chain product 8. Then, the piston rod of the fourth cylinder 5028 is extended, causing the clamping rod 5029 to release from the L-shaped plate 8. The limit is set at 02, then the piston rod of the third cylinder 5027 is extended, causing the clamping rod 5029 to move away from the L-shaped plate 802. Then the piston rod of the fifth cylinder 5036 is retracted, causing the receiving rack 5037 to move the mesh chain product 8 downward. Then the shaft of the fourth motor 5032 is reversed, moving the mesh chain product 8 out from under the support frame 5022. Then the stacking mechanism 3 places the flipped mesh chain product 8 on the receiving rack 5037 onto the stacking plate 6.
[0162] In this embodiment, a mesh chain auxiliary assembly mechanism 7 is provided at the feeding position. The mesh chain auxiliary assembly mechanism 7 is located between two support components 104. The mesh chain auxiliary assembly mechanism 7 includes a fifth support frame 701, which is fixed on the first base 101. A sixth cylinder 702 is fixedly installed at the bottom of the fifth support frame 701. A lifting seat 703 is fixedly installed at the top of the piston rod of the sixth cylinder 702. Steel bar limiting seats 704 are fixedly installed on the top of both sides of the lifting seat 703. Several limiting grooves 705 are opened on the steel bar limiting seats 704. The steel bars 801 on the mesh chain product 8 pass through the limiting grooves 705.
[0163] When loading materials at the loading position, first control the piston rod of the sixth cylinder 702 to extend, thereby making the height of the lifting seat 703 exceed the support component 104. Then, the steel strip 801 on the mesh chain product 8 is inserted into the limiting groove 705 to assist in assembly and positioning. Then, the L-shaped plate 802 is inserted into the end of the steel strip 801 through the insertion hole 803. After assembly, control the piston rod of the sixth cylinder 702 to retract, thereby making the assembled mesh chain product 8 sit on the support component 104. Then, manually check whether the limiting pin holes 805 at both ends of the mesh chain product 8 are fitted onto the corresponding positioning pins 1042 and tensioning pins 1043. If there is an error, it is assumed that the limiting pin hole 805 at one end of the mesh chain product 8 is inserted into the positioning pin 1042 and the limiting pin hole 805 at the other end is inserted into the tensioning pin 1043, making loading and assembly more convenient.
[0164] Working principle:
[0165] In the initial stage, at the loading position, the piston rod of the sixth cylinder 702 is first extended to make the height of the lifting seat 703 exceed that of the support assembly 104. Next, the steel bars 801 on the mesh chain product 8 are threaded into the limiting grooves 705 of the steel bar limiting seat 704; this step assists in assembly and positioning. Then, the L-shaped plate 802 is inserted into the end of the steel bar 801 through the insertion hole 803. After assembly is complete, the piston rod of the sixth cylinder 702 is retracted, allowing the assembled mesh chain product 8 to sit on the support assembly 104. Finally, through manual inspection, it is ensured that the limiting pin holes 805 at both ends of the mesh chain product 8 are accurately fitted onto the corresponding positioning pins 1042 and tensioning pins 1043. If there is an error, manual adjustment is performed, inserting one end of the limiting pin hole 805 into the positioning pin 1042 and the other end into the tensioning pin 1043, thus completing the preparation work for the loading position.
[0166] Next, the conveying mechanism 1 begins operation. The second motor 105 is started, driving the worm gear inside the worm gearbox 1051 to rotate, which in turn causes the worm wheel to rotate, causing the external spline shaft 1052 to rotate, which in turn drives the sprocket 1054 to rotate. The chain moves accordingly, and the support mechanism on the chain also moves. The support plate 1041 of the support mechanism supports the mesh chain product 8. As the conveying progresses, when the mesh chain product 8 is conveyed to the side of the welding position, the first linear module 9 is activated, driving the tensioning push plate 901 to move. This pushes the sliding block 1045 to overcome the elastic force of the spring 1046, tensioning the mesh chain product 8, preparing it for subsequent welding operations.
[0167] The clamping mechanism 4 clamps and positions the mesh chain product 8 at the welding position. The upper clamping cylinder 4042 of the upper clamping unit 404 is activated, extending the piston rod and causing the upper clamping plate 4043 to move downwards, clamping the upper part of the mesh chain product 8. Simultaneously, the lower clamping cylinder 4052 of the lower clamping unit 405 is activated, extending the piston rod and causing the lower clamping plate 4053 to move upwards, clamping the lower part of the mesh chain product 8. This simultaneous clamping from both above and below ensures that the mesh chain product 8 will not shift during welding, guaranteeing welding accuracy.
[0168] Before welding, the correction mechanism corrects the L-shaped plates 802 at both ends of the mesh chain product 8. First, the third motor 4061 is controlled to rotate, driving the second lead screw 4062 to rotate. Since the threads at both ends of the second lead screw 4062 rotate in opposite directions, the distance between the two adjusting support plates 4064 can be adjusted, thereby adjusting the spacing between the two correction units 407 according to the size of the mesh chain product 8. Next, the piston rod of the electric cylinder 402 is controlled to extend, driving the lifting frame 403 to move downward, so that the upper end of the L-shaped plate 802 is positioned between the first correction plate 40791 and the second correction plate 40792. Then, the piston rod of the first cylinder 4079 is controlled to retract, driving the first correction plate 40791 to move towards the second correction plate 40792, clamping the upper end of the L-shaped plate 802. Then, the slide of the second linear module 4071 is moved, which drives the first rack 4075 to move, thereby causing the first gear 4077 meshing with it to rotate, which drives the rotating shaft 4076 to rotate, and finally drives the flip plate 4078 to rotate, thereby adjusting the angle of the L-shaped plate 802 to make it vertical.
[0169] Then, welding robot 2 begins its work. Two welding robots 2, positioned on either side of the welding station, weld the ends of the steel bars 801 in the mesh chain product 8 to the L-shaped plate 802 according to a preset program and path. Welding robots 2 can precisely control the welding position, angle, and welding parameters, ensuring the stability and consistency of the welding quality.
[0170] After welding, the stacking mechanism 3 places the welded mesh chain products 8 onto the stacking plate 6 in alternating forward and reverse positions. The X-axis drive motor 3021 starts, driving the transmission rod 3022 to rotate, causing the X-axis transmission gear 3024 to mesh with the X-axis rack 3023, and the X-axis crossbeam 302 to slide on the X-axis slide rail 3025. The Y-axis drive motor 3031 starts, driving the Y-axis transmission gear to mesh with the Y-axis rack 3032, and the Y-axis support 303 to slide on the Y-axis slide rail 3033. The Z-axis drive motor 3041 starts, driving the Z-axis transmission gear to mesh with the Z-axis rack 3042, and the Z-axis support rod 304 to slide on the Z-axis slide rail 3044. Through the coordinated movement of the X, Y, and Z axes, the clamping mechanism reaches above the welded mesh chain products 8. The clamping motor 305 starts, driving the connecting shaft to rotate, causing the second synchronous gear 3051 to rotate. Through the second synchronous toothed belt 3052, the first gripper 3055 slides on the second slide rail 3053, cooperating with the second gripper 3056 to clamp the wire mesh product 8 and move it to the palletizing plate 6 for stacking.
[0171] When the welded mesh chain product 8 needs to be flipped, the stacking mechanism 3 first moves the welded mesh chain product 8 onto the support frame 5022 of the flipping mechanism 5 and releases it. Then, the piston rod of the third cylinder 5027 retracts, causing the fourth cylinder 5028 to move towards the center of the support frame 5022, so that the clamping rod 5029 moves above the L-shaped plate 802 at the end of the mesh chain product 8. Next, the piston rod of the fourth cylinder 5028 retracts, pressing the clamping rod 5029 against the lower end of the L-shaped plate 802, fixing the mesh chain product 8. Afterwards, the piston rod of the second cylinder 5024 extends, causing the second rack 5025 to move upward, rotating the second gear 5026, which in turn rotates the support frame 5022 via the rotating rod 5023, flipping the mesh chain product 8 180°. At this time, the shaft of the fourth motor 5032 is rotated, driving the third synchronous toothed belt 50321 to rotate, causing the transfer seat 5033 to move towards the mesh chain product 8. When the transfer seat 5033 moves directly under the mesh chain product 8, the piston rod of the fifth cylinder 5036 is extended, causing the receiving rack 5037 to abut against the steel strip 801 of the mesh chain product 8. Then, the piston rod of the fourth cylinder 5028 is extended, releasing the clamping rod 5029 from limiting the L-shaped plate 802. Then, the piston rod of the third cylinder 5027 is extended, causing the clamping rod 5029 to move away from the L-shaped plate 802. Finally, the piston rod of the fifth cylinder 5036 is retracted, the receiving rack 5037 moves the mesh chain product 8 downward, the shaft of the fourth motor 5032 is reversed, and the mesh chain product 8 is moved out from under the support frame 5022. Then, the stacking mechanism 3 places the flipped mesh chain product 8 onto the stacking plate 6. This completes the entire operation process of the mesh chain welding machine, from feeding the mesh chain products, welding, correcting, stacking, and flipping the materials when necessary.
