Description

Technical Field

[0001] This invention relates to the technical field of building construction, and in particular to an automatic welding machine for steel mesh. Background Technology

[0002] Reinforcing mesh is a mesh structure material made of reinforcing bars through welding or weaving. It forms a regular grid plane through the cross welding of longitudinal and transverse reinforcing bars, possessing excellent tensile and compressive strength, effectively bearing external loads and improving overall structural stability. It is widely used in road paving, bridge construction, and building construction, significantly simplifying on-site reinforcing bar binding procedures, reducing reliance on manual labor, shortening project cycles, and improving construction accuracy and material utilization. However, current welding equipment generally suffers from insufficient welding size adjustment capabilities. The equipment can only weld mesh of a single specification at a fixed spacing, unable to dynamically adjust the spacing of transverse or longitudinal reinforcing bars according to actual project needs. When producing reinforcing mesh of different sizes or grid parameters, operators must stop the machine to replace special fixtures or recalibrate the entire mechanical structure, leading to frequent production line interruptions, lengthy equipment changeover times, and a significant decrease in production efficiency. Furthermore, fixed welding machines are difficult to adapt to temporary changes on the construction site, such as mesh density adjustments or custom sizes, resulting in wasted equipment resources and increased costs, severely restricting the flexibility and large-scale application of construction production. This limitation makes existing technologies rigid in the face of diverse engineering needs, failing to meet the modern construction industry's urgent expectations for efficient and flexible manufacturing. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic welding machine for steel mesh to solve at least some of the above-mentioned problems.

[0004] This invention provides an automatic welding machine for reinforcing mesh, including a worktable, a transverse reinforcing bar arrangement mechanism, a longitudinal reinforcing bar arrangement mechanism, and a welding mechanism. The transverse reinforcing bar arrangement mechanism includes a fixed bearing component, a movable bearing component, and a first sliding adjustment component. The fixed bearing component is fixed to the worktable and has several first reinforcing bar sleeves with adjustable spacing. The movable bearing component has several second reinforcing bar sleeves with adjustable spacing. The movable bearing component is slidably connected to the worktable in the transverse direction via the first sliding adjustment component. The longitudinal reinforcing bar arrangement mechanism includes a mounting base and a second sliding adjustment component. The second sliding adjustment component is connected to the worktable. The mounting base has a reinforcing bar storage cavity for supporting longitudinal reinforcing bars. The mounting base is connected to the output end of the second sliding adjustment component for moving and spacing longitudinal reinforcing bars onto the transverse reinforcing bars in the transverse direction of the worktable. The welding mechanism includes several welding guns, which are connected to the mounting base with adjustable spacing. The first and second reinforcing bar sleeves correspond one-to-one with the welding guns. The first and second reinforcing bar sleeves are respectively connected to the two ends of the transverse reinforcing bars. The welding guns weld the connection points between the transverse and longitudinal reinforcing bars to form a reinforcing mesh.

[0005] Furthermore, the fixed bearing component has the same structure as the movable bearing component, both including a rebar mounting base and a plurality of rebar sleeve positioning components. A plurality of first rebar sleeves and second rebar sleeves slide on the corresponding rebar mounting bases, and a plurality of rebar sleeve positioning components correspond to the first rebar sleeves and second rebar sleeves respectively, for positioning them within the corresponding rebar mounting bases.

[0006] Furthermore, the first rebar sleeve and the second rebar installation sleeve have the same structure, both including an insertion hole for inserting the transverse rebar and a rebar positioning component. The rebar positioning component can be adjusted and inserted into the insertion hole to hold and position the transverse rebar.

[0007] Furthermore, the first sliding adjustment assembly includes a slide groove disposed on the longitudinal side of the worktable, a first driving member, a first driving screw, and a first threaded sleeve. The first driving member is connected to the worktable, the first threaded sleeve is fixedly connected to the movable bearing assembly, the first driving screw is connected to the output end of the first driving member, and the first threaded sleeve is sleeved on the first driving screw and slides within the slide groove.

[0008] Furthermore, one side of the mounting base is provided with a rebar pushing assembly, which is used to push the longitudinal rebar in the rebar storage cavity onto the transverse rebar, and the bottom of the mounting base is provided with support wheels that slide on the worktable.

[0009] Furthermore, the rebar storage cavity is arranged vertically along the mounting base. The rebar storage cavity includes a first L-shaped cavity and a second L-shaped cavity, which are inverted and connected to each other. The rebar pushing assembly is located in the connecting channel between the first L-shaped cavity and the second L-shaped cavity. The width of the first L-shaped cavity and the second L-shaped cavity is greater than the outer diameter of the longitudinal rebar but less than the outer diameter of the two longitudinal rebars, to ensure that the longitudinal rebars are stacked one layer at a time within the cavity.

[0010] Furthermore, the welding mechanism is located on one side of the mounting base. The welding mechanism includes a welding mounting base and several welding positioning components. Several welding guns slide within the welding mounting base, and the several welding positioning components correspond one-to-one with the welding guns to position the welding guns within the welding mounting base.

[0011] Furthermore, the second sliding adjustment assembly includes a support column, a second driving member, a second driving screw, and a second threaded sleeve disposed on the worktable. The second driving member is connected to the support column, the second threaded sleeve is fixedly connected to the mounting base, the second driving screw is connected to the output end of the second driving rod, and the second threaded sleeve is sleeved on the second driving screw.

[0012] Furthermore, the welding machine also includes a cutting mechanism, which includes a cutting blade, a first U-shaped frame, and cutting drive components. The first U-shaped frame is connected to the workbench and is located above the fixed support assembly. A plurality of cutting drive components are connected to the first U-shaped frame with adjustable spacing. A plurality of the cutting blades are connected to the corresponding cutting drive components for cutting the ends of the corresponding transverse reinforcing bars.

[0013] Furthermore, the welding machine also includes a lifting mechanism, which includes a lifting plate, a lifting drive component, and a second U-shaped frame. The second U-shaped frame is connected to the bottom of the workbench and is located between the fixed bearing component and the movable bearing component. The lifting drive component is connected to the second U-shaped frame, and the lifting plate is connected to the output end of the lifting drive component. This mechanism is used to provide auxiliary support for the reinforcing mesh and prevent the reinforcing mesh from deforming or shifting during the welding process.

[0014] The beneficial effects of this plan are as follows: By using adjustable-spacing rebar sleeves and welding guns, along with a slidable and adjustable load-bearing and rebar layout structure, the spacing of transverse and longitudinal rebars can be flexibly adjusted according to actual engineering needs. This allows for the production of rebar mesh with different specifications and parameters without the need to stop the machine to replace fixtures or recalibrate the entire equipment structure, reducing production line downtime. It can flexibly meet diverse production needs and has the advantages of flexibly adjusting the rebar spacing, adapting to the production of rebar mesh with different specifications, improving production efficiency, and enhancing production flexibility.

[0019] See Figure 1-6 This embodiment discloses an automatic rebar mesh welding machine, including a worktable 101, a transverse rebar 124 arranging mechanism, a longitudinal rebar 125 arranging mechanism, and a welding mechanism. Support legs 102 are provided below the worktable 101. The transverse rebar 124 arranging mechanism includes a fixed bearing component, a movable bearing component, and a first sliding adjustment component. The fixed bearing component is fixed to the worktable 101 and has several first rebar sleeves 112 with adjustable spacing. The movable bearing component has several second rebar sleeves 118 with adjustable spacing. The movable bearing component is slidably connected to the worktable 101 in the transverse direction via the first sliding adjustment component. The longitudinal rebar 125 arranging mechanism includes a mounting base 105 and a second sliding adjustment component. The second sliding adjustment component is connected to the workbench 101. The mounting base 105 is provided with a steel bar storage cavity 106 for supporting the longitudinal steel bars 125. The mounting base 105 is connected to the output end of the second sliding adjustment component for moving and spacing the longitudinal steel bars 125 onto the transverse steel bars 124 along the transverse direction of the workbench 101. The welding mechanism includes several welding guns 109, which are connected to the mounting base 105 with adjustable spacing. The first steel bar sleeve 112 and the second steel bar sleeve 118 correspond one-to-one with the welding guns 109. The first steel bar sleeve 112 and the second steel bar sleeve 118 are respectively connected to the two ends of the transverse steel bars 124. The welding guns 109 weld the connection between the transverse steel bars 124 and the longitudinal steel bars 125 to form a steel mesh.

[0020] The workbench 101 is provided with an adjustment groove 110, and the movable bearing component and the fixed bearing component are respectively located at both ends of the adjustment groove 110.

[0021] The automatic rebar mesh welding machine of this application achieves flexibility in adjusting the size of the transverse rebars 124 through the adjustable spacing of the first rebar sleeve 112 and the second rebar sleeve 118 of the transverse rebar arrangement mechanism, and the first sliding adjustment component of the movable bearing assembly. Simultaneously, the mounting base 105 of the longitudinal rebar arrangement mechanism can arrange the longitudinal rebars 125 at intervals through the movement of the second sliding adjustment component. Combined with the adjustable spacing of the welding gun 109 in the welding mechanism, the welding point spacing becomes variable. Therefore, this welding machine can adapt to the production needs of rebar meshes of different sizes and specifications, significantly improving the adjustment flexibility and adaptability of the production line.

[0022] In one embodiment, the fixed load-bearing component and the movable load-bearing component have the same structure, both including a rebar mounting base 105 and a plurality of rebar sleeve positioning members. A plurality of first rebar sleeves 112 slide on the first rebar mounting base 111105, and second rebar sleeves 118 slide on the second rebar mounting base 114. The plurality of rebar sleeve positioning members correspond to the first rebar sleeves 112 and the second rebar sleeves 118 respectively, and are used to position them within the corresponding rebar mounting base 105. The fixed load-bearing component and the movable load-bearing component adopt the same structural design, which not only simplifies the manufacturing and maintenance process of the components and reduces production costs, but also improves the versatility and interchangeability of the entire system.

[0023] The rebar mounting base 105 is typically designed as a long strip or frame structure, with guide grooves or rails integrated on its surface or inside to ensure that the rebar sleeves can move smoothly and accurately along a preset path when adjusting the spacing. Its material is usually a high-strength, wear-resistant metal, such as precision-machined steel or aluminum alloy, to ensure structural stability and positioning accuracy under long-term high-intensity use. The rebar sleeve positioning component is a key component for accurately fixing the rebar sleeves to the rebar mounting base 105. After the first rebar sleeve 112 and the second rebar sleeve 118 are adjusted to the required spacing of the transverse rebars 124, the rebar sleeve positioning component can reliably lock them, preventing any unnecessary displacement during welding due to mechanical vibration, thermal expansion, or external impact. There are various ways to implement the positioning of the rebar sleeve. For example, a bolt fastening mechanism can be used, which generates sufficient friction between the rebar sleeve and the rebar mounting seat 105 by tightening the bolts or achieves mechanical locking. Alternatively, a quick clamping mechanism can be used, such as eccentric wheel clamping, lever clamping, or pneumatic clamping device. These mechanisms allow operators to quickly position and unlock the rebar sleeve, thereby improving operational efficiency. In addition, a series of corresponding holes can be set on the rebar sleeve and the rebar mounting seat 105 by inserting pins into preset holes, and precise positioning and reliable fixing can be achieved by inserting pins.

[0024] When the spacing of the transverse reinforcing bars 124 needs to be adjusted, the operator can slide the first reinforcing bar sleeve 112 and the second reinforcing bar sleeve 118 along the guide structure on the reinforcing bar mounting base 105 to the target position according to production needs, and then reliably lock them using the reinforcing bar sleeve positioning device. This mechanism not only ensures the flexibility and accuracy of the transverse reinforcing bar 124 arrangement, adapting to the production of different mesh specifications, but also simplifies the operation process, improves production efficiency and welding quality, and ensures the geometric accuracy and welding strength of the reinforcing bar mesh due to the standardized structure.

[0025] In one embodiment, the first rebar sleeve 112 and the second rebar mounting sleeve have the same structure, both including a hole for inserting the transverse rebar 124 and a rebar positioning member. The rebar positioning member can be adjusted and inserted into the hole to hold and position the transverse rebar 124.

[0026] The insertion hole is a through-hole structure formed inside the first rebar sleeve 112 and the second rebar sleeve 118. Its main function is to provide an initial insertion space and guide for the transverse rebar 124. The transverse rebar 124 is first inserted into the insertion hole, which provides an initial limiting space. Subsequently, an adjustable rebar positioning member is placed into the insertion hole, which precisely clamps and positions the transverse rebar 124 by abutting it.

[0027] When a set screw is used as a rebar positioning component, its threaded end can be inserted into the insertion hole by rotating the set screw until it contacts the transverse rebar 124 and applies a preset clamping force. When an eccentric cam is used, the eccentric part of the camshaft gradually extends into the insertion hole and abuts against the rebar by rotating the camshaft. This adjustability allows the system to adapt to transverse rebars 124 of different diameters and to fine-tune the position of the rebar within the insertion hole, ensuring that the rebar is in an ideal positioning state before welding.

[0028] In one embodiment, both the welding positioning component and the rebar sleeve positioning component include a first telescopic rod 119 and a pressure plate 120. The welding gun 109, the first rebar sleeve 112, and the second rebar sleeve 118 are all supported by the corresponding pressure plate 120. The first telescopic rod 119 is used to adjust the supporting force of the pressure plate 120 to ensure the stable fixing of the welding gun 109, the first rebar sleeve 112, and the second rebar sleeve 118, and to ensure that they can maintain a stable position during the welding process, thereby improving welding accuracy and stability.

[0029] In one embodiment, multiple scales 121 are provided on the side end face of the welding mounting base 108, the upper end face of the first rebar mounting base 111105, and the upper end face of the second rebar mounting base 114. Indicating arrows 122 are provided on the welding gun 109, the first rebar sleeve 112, and the second rebar sleeve 118, and the indicating arrows 122 point to the corresponding scales 121. The scales 121 and the indicating arrows 122 provide the operator with intuitive measurement and positioning means, which facilitates quick and accurate adjustment of the position of the welding gun 109, the first rebar sleeve 112, and the second rebar sleeve 118, thereby improving work efficiency and accuracy.

[0030] In one embodiment, the first sliding adjustment assembly includes a slide groove 113 disposed on the longitudinal side of the workbench 101, a first driving member 123, a first driving screw 117, and a first threaded sleeve 116. The first driving member 123 is connected to the workbench 101, the first threaded sleeve 116 is fixedly connected to the second steel bar mounting seat 114, the first driving screw 117 is connected to the output end of the first driving member 123, and the first threaded sleeve 116 is sleeved on the first driving screw 117 and slides in the slide groove 113.

[0031] The slide 113 provides a precise guide track for the movable load-bearing component, ensuring its stability during lateral movement. The first drive member 123 provides a reliable power source, driving the first drive screw 117 to rotate. The first threaded sleeve 116 is fixedly connected to one end of the movable second rebar mounting seat 114 and sleeved on the first drive screw 117. The other end of the second rebar mounting seat 114 is provided with a slide rod 115, which is fixed to the worktable 101. This efficiently and precisely converts the rotational motion of the drive screw into the linear movement of the movable load-bearing component. This design enables the movable load-bearing component to achieve high-precision and high-efficiency lateral position adjustment, thereby precisely controlling the spacing of the lateral rebars 124.

[0032] In one embodiment, a welding mechanism is provided on one side of the mounting base 105. The welding mechanism includes a welding mounting base 108 and a plurality of welding positioning elements. A plurality of welding guns 109 slide within the welding mounting base 108. The plurality of welding positioning elements correspond one-to-one with the welding guns 109 and are used to position the welding guns 109 within the welding mounting base 108.

[0033] The welding mounting base 108 provides a uniform and stable sliding platform for the welding guns 109, allowing each welding gun 109 to flexibly adjust its spacing within the welding mounting base 108 according to the mesh size requirements of the reinforcing mesh. Once adjusted, the welding positioning component corresponding to each welding gun 109 can firmly lock it in the preset position, thereby ensuring that the welding gun 109 will not shift or vibrate during the welding process.

[0034] In one embodiment, the second sliding adjustment assembly includes a support column disposed on the worktable 101, a second driving member 104, a second driving screw 103 and a second threaded sleeve. The second driving member 104 is connected to the support column, the second threaded sleeve is fixedly connected to the mounting base 105, the second driving screw 103 is connected to the output end of the second driving rod, and the second threaded sleeve is sleeved on the second driving screw 103.

[0035] The second threaded sleeve is fixedly connected to the mounting base 105 and sleeved on the second drive screw 103, so that the second drive member 104 can precisely move the mounting base 105 in a straight line along the transverse direction of the worktable 101 through the precise rotation of the second drive screw 103. This structure has good self-locking and load-bearing capacity, so that the mounting base 105 can be stably held in the designated position after stopping movement, further improving the automation level and production efficiency of the equipment.

[0036] See further Figure 7-10 In another embodiment, a pusher assembly 107 is provided on one side of the mounting base 105. The pusher assembly 107 is used to push the longitudinal reinforcing bar 125 in the reinforcing bar storage cavity 106 onto the transverse reinforcing bar 124. The bottom of the mounting base 105 is provided with a support wheel 205 that slides on the worktable 101.

[0037] The rebar pushing assembly 107 includes a push plate 204 and two third telescopic rods 203. The push plate 204 is slidably connected to the mounting base 105 and is located at the lower end of the L-shaped rebar storage cavity 106. The push plate 204 is also fixedly connected to the corresponding third telescopic rod 203 and is located at the output end of the two third telescopic rods 203. The two third telescopic rods 203 are respectively fixedly connected to the mounting base 105 and are located at the end face of the mounting base 105. The rebar pushing assembly 107 can automatically push out the longitudinal rebars 125 stored in the L-shaped rebar storage cavity 106, which facilitates subsequent welding operations, reduces the complexity of manual operation, and improves the degree of automation.

[0038] Two support wheels 205 are provided below the mounting base 105. The worktable 101 has wheel grooves 206 on both sides, and the two support wheels 205 are located in the corresponding wheel grooves 206. The arrangement of the support wheels 205 and the wheel grooves 206 allows the mounting base 105 to move smoothly on the worktable 101, which facilitates the adjustment of the welding position. It also reduces the load of the weight of the mounting base 105 on the second first drive screw 117 and improves the service life of the equipment.

[0039] A rebar pushing assembly 107 is provided on one side of the mounting base 105, which is used to push the longitudinal rebars 125 in the rebar storage cavity 106 onto the transverse rebars 124, realizing the automation and precision of the longitudinal rebars 125 from storage to placement. This avoids the need for manual intervention, significantly improves the efficiency and accuracy of rebar placement, and reduces errors and production interruptions that may be caused by manual operation. At the same time, by providing support wheels 205 that slide on the worktable 101 at the bottom of the mounting base 105, the frictional resistance of the mounting base 105 during transverse movement is effectively reduced, making the movement of the mounting base 105 more stable, smooth, and precise. This not only improves the positioning accuracy of the longitudinal rebars 125 placement but also reduces the driving load of the second sliding adjustment assembly, extends the service life of the equipment, and ensures the consistency and reliability of the rebar mesh welding quality.

[0040] In one embodiment, the rebar positioning component includes a second telescopic rod 201, the output end of which is provided with a rebar holding block 202, and the rebar holding block 202 extends into both the first rebar sleeve 112 and the second rebar sleeve 118. The rebar is further fixed and positioned by the rebar holding block 202 to ensure that the rebar will not be displaced during the welding process, thereby improving the welding quality.

[0041] In one embodiment, the rebar storage cavity 106 is arranged vertically along the mounting base 105. The rebar storage cavity 106 includes a first L-shaped cavity 210 and a second L-shaped cavity 211, which are inverted and connected to each other. The rebar pushing assembly 107 is disposed in the connecting channel 209 between the first L-shaped cavity 210 and the second L-shaped cavity 211. The width of the first L-shaped cavity 210 and the second L-shaped cavity 211 is greater than the outer diameter of the longitudinal rebar 125 but less than the outer diameter of the two longitudinal rebars 125, so as to ensure that the longitudinal rebars 125 are stacked one layer at a time in the cavity.

[0042] One end of the L-shaped rebar storage cavity 106 has an inlet end 207, and the other end of the L-shaped rebar storage cavity 106 has an outlet end 208. The outlet end 208 is provided with a first L-shaped cavity 210 and a second L-shaped cavity 211, and a connecting channel 209 is formed between the first L-shaped cavity 210 and the second L-shaped cavity 211. Through the formed connecting channel 209, the longitudinal rebar 125 pushed out from the L-shaped rebar storage cavity 106 is limited and guided to ensure that the rebar can accurately enter the welding position and further improve the welding accuracy.

[0043] The rebar storage cavity 106 is arranged along the vertical direction of the mounting base 105, that is, its main extension direction is parallel to the direction of gravity. This vertical arrangement allows the longitudinal rebars 125 to fall or stack automatically under their own weight within the rebar storage cavity 106, thereby facilitating subsequent ejection operations and reducing reliance on additional conveying mechanisms.

[0044] These two L-shaped cavities are connected in an inverted manner, forming a channel with a specific geometry. This structural design allows the longitudinal reinforcing bars 125 to be effectively guided and constrained within the cavities, preventing disordered stacking or jamming of the reinforcing bars. The reinforcing bar pushing assembly 107 is positioned on the connecting channel 209 between the first L-shaped cavity 210 and the second L-shaped cavity 211, and can directly act on the longitudinal reinforcing bars 125 located at the connecting position, thereby achieving precise pushing out of the longitudinal reinforcing bars 125. It is understood that the connecting channel 209 is a horizontal channel, with its two ends connected to staggered vertical channels. The vertical channel of the first L-shaped cavity 210 is used to store the longitudinal reinforcing bars 125, and the vertical channel of the second L-shaped cavity 211 is used to restrict the feeding position of the longitudinal reinforcing bars 125 during the feeding process, avoiding feeding failure or multiple feeding out due to positional deviation.

[0045] To further ensure the orderly supply of longitudinal reinforcing bars 125, the widths of the first L-shaped cavity 210 and the second L-shaped cavity 211 are precisely designed. This width is greater than the outer diameter of a single longitudinal reinforcing bar 125 to allow it to pass smoothly; simultaneously, this width is less than the outer diameters of two longitudinal reinforcing bars 125, thus strictly limiting the stacking method of the longitudinal reinforcing bars 125 within the cavity, ensuring that they can only exist in a single-layer, stacked manner. This dimensional limitation effectively prevents multiple layers of longitudinal reinforcing bars 125 from stacking or intersecting within the cavity, fundamentally solving the problems of reinforcing bar jamming or the simultaneous ejection of multiple reinforcing bars.

[0046] When using the automatic rebar mesh welding machine of this embodiment, the rebar holding block 202 further fixes and positions the rebar, ensuring that the rebar will not shift during welding, thereby improving welding quality. The rebar pushing assembly 107 can automatically push out the longitudinal rebar 125 stored in the L-shaped rebar storage cavity 106, facilitating subsequent welding operations, reducing the complexity of manual operation, and improving the degree of automation. The setting of the support wheel 205 and the wheel groove 206 allows the mounting seat 105 to move smoothly on the worktable 101, facilitating the adjustment of the welding position, and also reducing the load of the weight of the mounting seat 105 on the second first drive screw 117, improving the service life of the equipment. The formed connecting channel 209 limits and guides the longitudinal rebar 125 pushed out from the L-shaped rebar storage cavity 106, ensuring that the rebar can accurately enter the welding position, further improving welding accuracy.

[0047] See Figure 11 In another embodiment, the welding machine further includes a cutting mechanism, which includes a cutting blade 301, a first U-shaped frame, and a cutting drive 302. The first U-shaped frame is connected to the workbench 101 and is located above the fixed support assembly. A plurality of cutting drive 302s are connected to the first U-shaped frame with adjustable spacing. A plurality of cutting blades 301 are connected to the corresponding cutting drive 302 for cutting the ends of the corresponding transverse reinforcing bars 124.

[0048] Driven by the cutting drive unit 302, the cutting blade 301 performs fixed-length processing on the transverse reinforcing bars 124, thereby avoiding material waste caused by mismatched lengths of the transverse reinforcing bars 124. At the same time, integrating the cutting function into the automatic welding process reduces manual intervention and subsequent processing steps, significantly improving the automation level and overall production efficiency of steel mesh production, reducing production costs, and ensuring the dimensional accuracy of the finished product.

[0049] In one embodiment, the welding machine further includes a lifting mechanism, which includes a lifting plate 304, a lifting drive 305, and a second U-shaped frame 306. The second U-shaped frame 306 is connected to the workbench 101 and is located between the fixed bearing component and the movable bearing component. The lifting drive 305 is connected to the second U-shaped frame 306, and the lifting plate 304 is connected to the output end of the lifting drive 305 to provide auxiliary support for the steel mesh and prevent the steel mesh from deforming or displacing during the welding process.

[0050] The lifting plate 304 is the component in the lifting mechanism that directly contacts the reinforcing mesh. It is typically designed as a plate-like structure with sufficient rigidity and flatness to evenly bear the weight of the reinforcing mesh. The lifting plate 304 can be made of high-strength steel or composite materials, and its surface can be treated with an anti-stick coating or have an anti-slip texture to prevent the reinforcing mesh from slipping during lifting. Its size and shape should match the size of the reinforcing mesh to be welded, or be designed to be adjustable to accommodate different mesh sizes.

[0051] When using the automatic rebar mesh welding machine of this embodiment, the cutting drive 302 drives the cutting blade 301, realizing automated cutting of the rebar mesh. This reduces the need for manual cutting and improves production efficiency. The first U-shaped frame 303 is fixedly connected to the worktable 101, without occupying additional workspace, making the entire welding machine structure more compact. The lifting drive 305 drives the lifting plate 304 to provide stable support for the rebar mesh, preventing deformation or displacement of the rebar mesh during welding and improving welding quality. At the same time, the height of the lifting mechanism can be flexibly adjusted by adjusting the output stroke of the lifting drive 305, enhancing the adaptability of the welding machine.

[0052] In this invention, the welding gun 109 is a prior art technology. Its automatic welding parameter adjustment system can dynamically adjust the welding current, voltage and speed according to the material, diameter and welding requirements of the steel bar to ensure the welding quality, thereby realizing the rapid welding of steel mesh and greatly improving production efficiency. At the same time, during the welding process, the welding quality can be monitored in real time by integrated sensors and data can be recorded to ensure the consistency and reliability of the weld quality.

[0053] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
