[0002] like Figure 1-Figure 2 As shown, existing mesh chain products typically consist of multiple parallel steel bars connected by spiral wires to form a mesh structure. L-shaped plates with sockets are placed at each end of the steel bars. The steel bars are inserted through the sockets and then welded to the L-shaped plates. These products are widely used in conveying equipment, filtration devices, and heat treatment furnace mesh belts. The quality of the welding directly affects the strength, flatness, and overall performance of the mesh chain.

[0037] Compared with the prior art, the present invention has the following beneficial effects:
[0038] Through the provision of conveying mechanism, welding robot, stacking mechanism, pressing mechanism, correction mechanism and turning mechanism, the fast welding of network chain products is achieved, manual operation is reduced, and production efficiency and product consistency are improved;
[0039] The first support base 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 adapt to mesh chain products of different sizes, improving the versatility of the equipment.
[0040] The positioning pins and tensioning pins of the support assembly cooperate with the sliding block through springs to prevent displacement during transportation. 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 the electric cylinder, and cooperates with the second spacing adjustment mechanism to adjust the spacing of the correction units. The linear module and gear rack drive drive the flip plate to rotate, which can accurately adjust the inclined L-shaped plate to a vertical state, ensuring the correct posture of the workpiece during welding and avoiding welding defects caused by angle deviation.
[0042] The upper and lower clamping units of the clamping mechanism drive the clamping plates through cylinders, simultaneously clamping the mesh chain products at the welding position from both ends to form a rigid fixation, effectively preventing vibration or displacement of the workpiece during welding, and improving welding accuracy and the qualified rate of finished products;
[0043] The palletizing mechanism uses the X, Y, and Z axis drive mechanisms to achieve three-dimensional movement of the clamping mechanism. It can accurately grab the welded mesh chain products and stack them on the palletizing board in an alternating forward and reverse manner, meeting the needs of orderly stacking and improving storage efficiency.
[0044] The turning mechanism uses a cylinder to drive the rack and pinion transmission to achieve a 180° turning of the support frame. In conjunction with the transfer component's receiving rack and cylinder action, the chain products can be automatically turned over without manual intervention, ensuring alternating positive and negative positions during palletizing to meet different packaging and transportation requirements.
[0045] The mesh chain auxiliary assembly mechanism at the loading position drives the lifting seat through a cylinder, so that the limit groove of the steel bar limit seat accurately positions the steel bars of the mesh chain product, and assists the L-shaped plate to insert the end of the steel bar, reducing the difficulty of manual alignment and improving loading efficiency and assembly accuracy.

The external spline shaft 1052 at both ends of the first support seat 102 is slidably connected to the sprocket 1054 through the internal spline, and the external spline shaft 1052 is connected to the second motor 105 through the worm gear box 1051. After the second motor 105 is started, it drives the worm in the worm gear box 1051 to rotate, and then the worm wheel rotates, driving the external spline shaft 1052 to rotate, thereby rotating the sprocket 1054. The rotation of the sprocket 1054 drives the chain, and the supporting mechanism on the chain moves accordingly. When adjusting the distance between the two first support bases 102, the lower end of the limit pin 1022 extends into the wheel groove of the pulley 1055, and the limit pin 1022 slides against the inner wall of the wheel groove of the pulley 1055. Therefore, when the first support base 102 moves, the sprocket 1054 moves with it. The supporting mechanism includes two sets of support assemblies 104. The support plate body 1041 of the support assembly 104 is fixed to the chain plate, which plays the role of supporting the mesh chain product 8.
[0103] Furthermore, a waist hole 1044 is formed on the support plate body 1041 of the support assembly 104 near one end of the tensioning pin 1043. A sliding block 1045 is slidably installed inside the waist hole 1044. The tensioning pin 1043 is fixed to the top of the sliding block 1045. Springs 1046 are 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, and a tensioning push plate 901 is fixedly installed on the slide of the first linear module 9. The first linear module 9 is arranged 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, thereby tensioning the network chain product 8.
[0105] During use, since the L-shaped plate 802 defines a limit pin hole 805, the limit pin hole 805 at one end of the mesh chain 8 is inserted over the positioning pin 1042, while the limit pin hole 805 at the other end is inserted over the tensioning pin 1043, thereby positioning the mesh chain 8. When the mesh chain 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 away from the positioning pin 1042 against the elastic force of the spring 1046, thereby tensioning the mesh chain 8 for subsequent welding operations.
[0106] After the mesh chain product 8 is delivered to the welding station, two welding robots 2, positioned on either side of the 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 precisely control the weld position, angle, and parameters, ensuring consistent and stable weld quality.
[0107] In this embodiment, the first spacing adjustment mechanism 103 includes a first motor 1031 and a first screw rod 1032. The threads at both ends of the first screw rod 1032 rotate in opposite directions. Both ends of the first screw rod 1032 are threadedly rotatably installed with a first movable seat 1035. The first movable seat 1035 is respectively fixed to the bottom of the first support seat 102 corresponding thereto. The first screw rod 1032 is rotatably installed on the first base 101 through a first seat bearing 1036. The first motor 1031 is fixed on the first base 101. A first synchronous gear 1033 is fixedly sleeved on the first screw rod 1032. The second synchronous gear is fixedly connected to the rotating shaft of the first motor 1031. The first synchronous gear 1033 and the second synchronous gear are transmission-connected by a first synchronous toothed belt 1034. A first slide rail 1037 is fixedly connected to the first base 101. The bottoms of the two first support seats 102 are both fixedly connected to a first slider 1038, and the first slider 1038 is slidably installed on the first slide rail 1037.
[0108] During use, the first motor 1031 is started, driving the second synchronous gear to rotate, which in turn rotates the first synchronous gear 1033 via the first synchronous belt 1034, thereby driving the first screw rod 1032 to rotate. Since the threads at the two ends of the first screw rod 1032 rotate in opposite directions, the first movable bases 1035 rotatably mounted at the two ends of the threads move closer to or further away from each other, thereby adjusting the distance between the two first support bases 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 .

[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, the piston rod extends, and the upper clamping plate 4043 moves downward, clamping the upper portion of the mesh chain product 8. Simultaneously, the lower clamping cylinder 4052 is activated, the piston rod extends, and the lower clamping plate 4053 moves upward, clamping the lower portion of the mesh chain product 8. This simultaneous clamping prevents displacement of the mesh chain product 8 during welding, ensuring 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 mounted 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 arranged on the inner side of the second support frame 401. Correction units 407 are provided on both sides of the lower end of the lifting frame 403. Two groups of correction units 407 are mounted on 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 screw rod 4062. The third motor 4061 is fixed to the lifting frame 403. The second screw rod 4062 is rotatably mounted on the lower end of the lifting frame 403 through a second seat bearing. The threads at both ends of the second screw rod 4062 are rotated in opposite directions. Both ends of the second screw rod 4062 are threadedly rotatably connected to the second movable seat 4063. The bottoms of the two second movable seats 4063 are 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 mounted on the third slide rail 4065.
[0115] The correction unit 407 includes a second linear module 4071 and a rotating shaft 4076. The adjustment support plate 4064 is set in an inverted U shape. The rotating shaft 4076 is rotatably mounted on the inner side of the lower end of the adjustment support plate 4064 through a bearing. The second linear module 4071 is fixed to the bottom of the adjustment support plate 4064. The bottom of the slide of the second linear module 4071 is fixedly connected to the movable seat 4074. The bottom of the movable seat 4074 is fixedly connected to the first rack 4075. The rotating shaft 4076 is fixedly sleeved with a first gear 4 077, the first gear 4077 is meshed with the first rack 4075, a fixed connection block 40761 is fixedly connected to the rotating shaft 4076, a flip plate 4078 is fixedly connected to the bottom of the fixed connection block 40761, a first cylinder 4079 is fixedly mounted on the bottom of the flip plate 4078, the end of the piston rod of the first cylinder 4079 is fixedly connected to the first correction plate 40791, and a second correction plate 40792 is fixedly connected to the end of the cylinder body of the first cylinder 4079 away from the first correction plate 40791;

[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 plate 802 at both ends of the mesh chain product 8, so that it changes from a tilted state to a vertical state. The specific operation is to first control the rotation of the third motor 4061, thereby driving the second screw rod 4062 to rotate. Since the threads at both ends of the second screw rod 4062 have opposite rotation directions, and both ends are threadedly installed with a second movable seat 4063, the rotating second screw rod 4062 can drive the second movable seats 4063 at both ends to move toward or away from each other, thereby adjusting the distance between the two adjustment support plates 4064, and then adjusting the spacing between the two correction units 407 according to the size of the mesh chain product 8. Then, the piston rod of the electric cylinder 402 is controlled to extend, thereby driving the lifting frame 403 to move downward, so that the upper end of the L-shaped plate 802 is located 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 correction plate 40791 to move toward the second correction plate 40792, thereby clamping the upper end of the L-shaped plate 802, and then controlling the slide of the second linear module 4071 to move. The moving slide drives the first rack 4075 to move, thereby driving the first gear 4077 engaged with it to rotate, and the rotating first gear 4077 drives the rotating shaft 4076 to rotate, and the rotating rotating shaft 4076 drives the flip plate 4078 fixedly connected to it to rotate, thereby driving the first correction plate 40791 and the second correction plate 40792 to rotate, so that the angle of the L-shaped plate 802 can be adjusted to make it in a vertical state.
[0119] The correction unit 407 further includes a controller and an angle sensor, and the controller is configured to:
[0120] (a) Obtaining the tilt angle θ of the L-shaped plate 802 through an angle sensor;
[0121] (b) Calculating 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, driving the flip plate 4078 to rotate to correct the L-shaped plate.
[0123] Among them, the compensation equation expression is:
[0124]
[0125] Parameter Description:
[0126] Δs: moving distance of the second linear module 4071 slide (unit: mm);
[0127] θ: initial tilt angle of the L-shaped plate 802 (unit: radian);
[0128] d g : pitch circle diameter of the first gear 4077 (unit: mm);
[0129] c: Deformation compensation coefficient (unit: 1 / radian), calibrated by experiments (typical value range: 0.02–0.1).
[0130] Example:
[0131] 1. Detecting the tilt angle: The angle sensor measures the initial tilt angle of the L-shaped plate, θ = 0.1 rad (about 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 = 1.005 mm, driving the flip plate 4078 to rotate and correct the angle.
[0135] The technical effect of this solution
[0136] Improved precision: Compensates for nonlinear errors caused by mechanism gaps and material elasticity. After correction, the vertical deviation of the L-shaped plate is ≤0.2°.
[0137] Efficiency optimization: avoid repeated adjustments and significantly shorten the time required for a single correction.
[0138] Enhanced reliability: prevents plate deformation or mechanism overload caused by overcorrection.
[0139] Working Principle Process
[0140] 1. Detection stage:
[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] The angle sensor measures the tilt angle θ in real time.
[0143] 2. Calculation phase:
[0144] The controller calculates Δs according to the equation, integrating the gear diameter dg and the experimentally calibrated compensation coefficient c.
[0145] 3. Execution phase:
[0146] The second linear module 4071 moves by Δs, and is driven by the first rack 4075 and the first gear 4077 to drive the flip plate 4078 to rotate.
[0147] The L-shaped plate is precisely adjusted to a vertical state (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 the gear rack transmission of the deep coupling correction mechanism (d g ) and material deformation characteristics (c); the quadratic term θ 2 Aiming at the elastic deformation error observed in the experiment, the problem of insufficient accuracy of the linear model in the existing technology is solved; the coefficient c needs to be optimized through experiments for different network chain products to reflect customized design and significantly improve the correction accuracy and efficiency.

[0162] In this embodiment, a mesh chain auxiliary assembly mechanism 7 is provided at the loading position, and the mesh chain auxiliary assembly mechanism 7 is located between the two support components 104. The mesh chain auxiliary assembly mechanism 7 includes a fifth support frame 701, and the fifth support frame 701 is fixed on the first base 101. The bottom of the fifth support frame 701 is fixedly installed with a sixth cylinder 702, and the top of the piston rod of the sixth cylinder 702 is fixedly installed with a lifting seat 703. The tops of both sides of the lifting seat 703 are fixedly installed with steel bar limit seats 704, and the steel bar limit seats 704 are provided with a number of limit grooves 705. The steel bars 801 on the mesh chain product 8 are inserted into the limit grooves 705.
[0163] When loading at the loading position, first control the piston rod of the sixth cylinder 702 to extend, so that the height of the lifting seat 703 exceeds the support assembly 104, and then the steel bar 801 on the mesh chain product 8 is inserted into the limit groove 705 to assist in assembly and positioning, and then the L-shaped plate 802 is inserted into the end of the steel bar 801 through the socket 803. When the assembly is completed, control the piston rod of the sixth cylinder 702 to retract, so that the assembled mesh chain product 8 is seated on the support assembly 104, and then manually check whether the limit pin holes 805 at both ends of the mesh chain product 8 are sleeved on the corresponding positioning pins 1042 and tensioning pins 1043. If there is an error, it is considered that the limit pin hole 805 at one end of the mesh chain product 8 is inserted on the positioning pin 1042, and the limit pin hole 805 at the other end is inserted on the tensioning pin 1043, so that loading and assembly are more convenient.
[0164] Working principle:
[0165] In the initial stage, at the loading position, first control the piston rod of the sixth cylinder 702 to extend so that the height of the lifting seat 703 exceeds the support assembly 104. Next, insert the steel bar 801 on the mesh chain product 8 into the limit groove 705 of the steel bar limit seat 704. This step serves to assist in assembly and positioning. Subsequently, insert the L-shaped plate 802 into the end of the steel bar 801 through the socket 803. After the assembly is completed, control the piston rod of the sixth cylinder 702 to retract, so that the assembled mesh chain product 8 is seated on the support assembly 104. Finally, through manual inspection, ensure that the limit pin holes 805 at both ends of the mesh chain product 8 are accurately fitted on the corresponding positioning pins 1042 and tensioning pins 1043. If there is an error, manually adjust it to insert the limit pin hole 805 at one end of the mesh chain product 8 into the positioning pin 1042 and the other end into the tensioning pin 1043, thereby completing the preparation work for the loading position.
[0166] Next, the conveyor mechanism 1 begins operation. The second motor 105 is activated, driving the worm in the worm gearbox 1051, which in turn rotates the worm wheel, prompting the external spline shaft 1052 to rotate, which in turn drives the sprocket 1054, which in turn moves the chain and the supporting mechanism on the chain. The support plate 1041 of the supporting mechanism supports the mesh chain product 8. As the mesh chain product 8 reaches the side of the welding position, the first linear module 9 activates, driving the tensioning push plate 901 to move, pushing the sliding block 1045 to overcome the elastic force of the spring 1046, tensioning the mesh chain product 8 and preparing for the subsequent welding operation.
[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, and the piston rod extends, driving the upper clamping plate 4043 downward to compress the upper portion of the mesh chain product 8. Simultaneously, the lower clamping cylinder 4052 of the lower clamping unit 405 is activated, and the piston rod extends, driving the lower clamping plate 4053 upward to compress the lower portion of the mesh chain product 8. This simultaneous clamping prevents displacement of the mesh chain product 8 during welding, ensuring 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 screw rod 4062 to rotate. Since the threads at both ends of the second screw rod 4062 rotate in opposite directions, the distance between the two adjustment support plates 4064 can be adjusted, and then the spacing between the two correction units 407 can be adjusted 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 located between the first correction plate 40791 and the second correction plate 40792. Then, the piston rod of the first air cylinder 4079 is controlled to retract, driving the first correction plate 40791 to move toward the second correction plate 40792, clamping the upper end of the L-shaped plate 802. Afterwards, the slide of the second linear module 4071 is controlled to move, driving the first rack 4075 to move, thereby rotating the first gear 4077 engaged therewith, driving the rotating shaft 4076 to rotate, and finally driving the flip plate 4078 to rotate, thereby adjusting the angle of the L-shaped plate 802 to make it in a vertical state.
[0169] Then, welding robots 2 begin their work. Positioned on either side of the welding station, they weld the ends of steel bars 801 and L-shaped plates 802 in the mesh chain product 8 according to a pre-set program and path. Welding robots 2 precisely control the weld position, angle, and parameters, ensuring consistent and stable welding quality.
[0170] After welding is completed, the stacking mechanism 3 stacks the welded mesh chain products 8 on the stacking plate 6 in an alternating forward and reverse pattern. The X-axis drive motor 3021 is activated, 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 is activated, driving the Y-axis transmission gear to mesh with the Y-axis rack 3032, and the Y-axis support base 303 to slide on the Y-axis slide rail 3033. The Z-axis drive motor 3041 is activated, 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 is started, driving the connecting shaft to rotate, causing the second synchronous gear 3051 to rotate, and driving the first clamping jaw 3055 to slide on the second slide rail 3053 through the second synchronous toothed belt 3052, cooperating with the second clamping jaw 3056 to clamp the network chain product 8 and move it to the stacking plate 6 for stacking.
[0171] When the welded mesh chain product 8 needs to be flipped and placed, 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. Subsequently, the piston rod of the third cylinder 5027 is controlled to retract, driving the fourth cylinder 5028 toward the center of the support frame 5022, causing the clamping rod 5029 to move above the L-shaped plate 802 at the end of the mesh chain product 8. Next, the piston rod of the fourth cylinder 5028 is controlled to retract, causing the clamping rod 5029 to press against the lower end of the L-shaped plate 802, securing the mesh chain product 8. Next, the piston rod of the second cylinder 5024 is controlled to extend, driving the second rack 5025 upward, causing the second gear 5026 to rotate. This, via the rotating rod 5023, causes the support frame 5022 to flip, flipping the mesh chain product 8 180°. At this point, the shaft of the fourth motor 5032 is controlled to rotate, driving the third synchronous toothed belt 50321 to rotate, causing the transfer base 5033 to move toward the mesh product 8. When the transfer base 5033 moves directly below the mesh product 8, the piston rod of the fifth cylinder 5036 is controlled to extend, causing the receiving rack 5037 to rest against the steel bars 801 of the mesh product 8. Next, the piston rod of the fourth cylinder 5028 is controlled to extend, releasing the clamping rod 5029 from the L-shaped plate 802. The piston rod of the third cylinder 5027 is then controlled to extend, moving the clamping rod 5029 away from the L-shaped plate 802. Finally, the piston rod of the fifth cylinder 5036 is controlled to retract, causing the receiving rack 5037 to move the mesh product 8 downward. The shaft of the fourth motor 5032 is controlled to reverse, removing the mesh product 8 from beneath the support frame 5022. The palletizing mechanism 3 then stacks the flipped mesh product 8 onto the palletizing plate 6. At this point, the complete operation process of the mesh chain welding machine has been completed, including loading, welding, correction, stacking and flipping of mesh chain products when necessary.
