Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a welding equipment for processing aluminum single-panel panels. Background Technology

[0002] The field of aluminum single-panel welding technology involves the splicing, positioning, clamping, bearing, conveying and welding of aluminum sheet components such as aluminum single-panel frames, side panels and borders during the processing. Its core aspects include determining the placement benchmark of aluminum single-panel components before welding, limiting support for edges and side panels, maintaining the posture of the workpiece during welding, the relative movement between the welding torch and the welding position, and unloading and resetting after welding. It usually requires the combination of a bearing platform, stop blocks, elastic clamping components, guide rails, lifting drive components and welding execution components to complete the transfer and processing of the workpiece from the loading position to the welding position.

[0003] Chinese Patent Publication No. CN223431125U discloses a welding equipment for aluminum single-panel processing, including a welding frame and a plate positioning plate. Multiple movable supports are fixedly connected to the center of the welding frame, and these movable supports are located on both sides of the outer wall of the plate positioning plate. The plate positioning plate is located on both sides inside the welding frame, and one side of the outer wall of the plate positioning plate is rotatably connected to the center of the movable supports via a rotating shaft. A double-threaded screw is rotatably connected to the center of the outer wall of the plate positioning plate. This prior art allows the plate positioning plate to rotate around the center of the movable supports. After the plate positioning plate rotates to a specified angle, the operator can weld the joints of the aluminum single-panel, thereby precisely adjusting the welding angle between the aluminum single-panel plates. This reduces the workload of the operator, improves production efficiency, further avoids errors that occur during manual adjustment, and ensures the consistency of the welding quality of the aluminum single-panel plates.

[0004] Existing technology mainly uses the rotation of the plate positioning plate around the movable support as its working method. The key is to change the welding angle at the joint of the aluminum single panel. When the aluminum single panel frame has side plates and needs to be moved between the loading position and the welding position, the angle adjustment of the plate positioning plate is difficult to continuously constrain the edge and side plate of the frame. Especially when the workpiece is subjected to welding heat or the welding gun moves relative to it, the side plates lack the upper, lower and circumferential cooperative abutment, which can easily cause outward expansion, tilting or corner displacement, thus affecting the joint fit and increasing the need for manual support and recalibration. Summary of the Invention

[0005] The main objective of this invention is to provide a welding device for aluminum single-panel processing, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A welding device for aluminum single-panel processing includes an installation cabinet and a control cabinet installed on one side of the installation cabinet.

Straight sliding grooves are symmetrically provided on both the front and rear sides of the upper end of the positioning support platform. Side plate positioning components for supporting the side plates are symmetrically arranged on the front and rear sides of the positioning support platform and are slidably connected to the two straight sliding grooves on the same side.

[0010] Preferably, the side plate positioning assembly includes a fixed stop block two fixedly connected to the upper end of the fixed stop block one, a limit guide rail fixedly connected to the inner surface of the two straight slide grooves on the same side, a connecting block slidably connected to the inner surface of the two limit guide rails, a sliding block two fixedly connected to the upper end of the two connecting blocks and slidably connected to the upper end of the limit guide rails, and a compression spring one abutting against the front end of the connecting block fixedly connected to the inner surface of the two limit guide rails.

[0011] Preferably, the welding positioning structure includes four rectangularly distributed connecting plates, each of which is fixedly connected to a mounting plate on the same side. The four connecting plates are jointly fixedly connected to a welding guide rail. A welding robotic arm is provided at the upper end of the welding guide rail. A plasma welding torch for welding aluminum single-panel frames is fixedly installed at the rotating arm of the welding robotic arm. An auxiliary positioning support platform for positioning the aluminum single-panel frames for welding is provided at the lower end of the welding guide rail.

[0012] Preferably, the welding guide rail includes a rectangular plate fixedly connected to the connecting plate. A guide groove is provided at the upper end of the rectangular plate. An electric trolley is movably mounted on the inner surface of the guide groove. A mounting seat for mounting a welding robotic arm is fixedly connected to the upper end of the electric trolley. Cables are symmetrically fixedly connected to the lower end of the electric trolley. The cables are rectangularly distributed and pass through the inner cavity of the rectangular plate and slide within the inner cavity of the rectangular plate.

[0013] Preferably, the welding guide rail further includes cross grooves formed at the four corners of the lower end of the rectangular plate, a cross slider is slidably connected to the inner wall of the cross groove, a damping ring sleeved on the outer surface of the cable is fixedly connected to the middle of the inner surface of the cross slider, and a clamping arm for abutting against the side plate of the welding aluminum single-panel frame is fixedly connected to the lower end of the cross slider.

[0014] Preferably, the positioning auxiliary component includes a sliding guide rail symmetrically fixedly connected to the lower end of the rectangular plate.

A connecting rod I, which is rotatably connected to the adjacent end face of the limit frame, is rotatably connected to the two hinge seats.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, through the cooperation of the guide structure and the positioning support platform, enables the aluminum single-panel frame to be loaded outside the mounting cabinet and then smoothly pushed into the welding area. The primary slide rail, sliding plate, and movable slider together restrict the pulling direction, the baffle reduces excessive outward movement of the primary slide rail, and the guide column and buffer washer provide vertical guidance and buffer support during lifting. In the lifting drive structure, the drive motor drives the screw to move the lifting platform along the sliding cavity, and the T-shaped plate supports the positioning support platform, so that the workpiece maintains good load-bearing stability and positional continuity when transitioning from the loading position to the welding positioning structure.

[0016] 2. This invention achieves edge clamping of aluminum single-panel frame components by cooperating with a fixed stop block 1 and a sliding block 1 on the positioning support platform. The fixed stop block 1 provides a backing reference, and the spring limiting rod slides within the positioning plate and pushes the sliding block 1 against the workpiece, giving the clamping process elastic compensation capability. In conjunction with anti-slip stripes, contact friction is increased, reducing the possibility of slippage of the frame components during pulling, lifting, and welding. At the same time, the side plate positioning assembly uses a fixed stop block 2 and a sliding block 2 to form double-sided support for the side plate. The connecting block moves along the limiting guide rail and compresses the spring 1, keeping the sliding block 2 in a spring-loaded position, thereby enhancing the vertical support and edge fitting stability of the side plate and reducing deformation caused by side plate outward expansion, tilting, and rigid clamping.

[0017] 3. This invention achieves supplementary positioning of aluminum single-panel frame components in the welding area through the cooperation of welding positioning structure and positioning auxiliary components. The connecting plate supports the welding guide rail, so that the workpiece remains in a restricted state when the welding robot arm moves along the guide groove with the mounting seat and electric trolley. The cable links the cross slider and clamping arm to abut the side plate. The damping ring cooperates with the cross slide groove to slow down the clamping action. The limiting frame, compression spring two, telescopic limiting rod, push block, connecting rod two, hinge seat and connecting rod one further form a flexible abutment, thereby reducing the outward movement of the side plate, the lifting of the edge corners and the positional changes during welding.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1: This example provides a welding device for aluminum single-panel processing. (See attached document.) Figure 1 and Figure 2 The system includes an installation cabinet 1 and a control cabinet 6 installed on one side of the installation cabinet 1. The installation cabinet 1 forms the main installation space and welding operation space of the equipment. The control cabinet 6 is used to control the drive components and welding components in the equipment. A cabinet door 5 is rotatably installed on the front of the inner surface of the installation cabinet 1. When the cabinet door 5 is opened, it is convenient for operators to load, unload and inspect materials. When the cabinet door 5 is closed, it can shield and isolate the welding area inside the installation cabinet 1, reducing the impact of external contact, foreign objects entering and external disturbances on the positioning status of the aluminum single panel frame. The bottom wall of the inner cavity of the installation cabinet 1 is symmetrically provided with guide structures 7. The upper ends of the two guide structures 7 are jointly provided with positioning support platforms 4 for supporting the aluminum single panel frame. The positioning support platform 4 can move back and forth relative to the mounting cabinet 1 under the action of the guide structure 7, so that the aluminum single-panel frame can be placed and initially adjusted in a relatively open position outside the mounting cabinet 1, avoiding the operator from placing the workpiece directly in the deep part of the mounting cabinet 1. The two ends of the inner cavity of the mounting cabinet 1 are symmetrically fixed with lifting drive structures 2. The two lifting drive structures 2 are provided with a welding positioning structure 3 for welding the aluminum single-panel frame at their close ends. In use, the aluminum single-panel frame is first placed on the positioning support platform 4, and then the positioning component on the positioning support platform 4 completes the initial limiting. Then, the lifting drive structure 2 drives the positioning support platform 4 to rise, so that the aluminum single-panel frame enters the welding area corresponding to the welding positioning structure 3. The welding positioning structure 3 provides auxiliary restriction to the aluminum single-panel frame before welding. This structure enables the aluminum single-panel frame to complete the sequential pulling and feeding, bearing positioning, lifting and conveying, auxiliary pressing and moving welding, reducing the position change caused by multiple workpiece handling and making the frame state more stable before welding.

[0022] For further details, please refer to [link / reference]. Figure 2 and Figure 3The guide structure 7 includes a primary slide rail 75 slidably connected to the bottom wall of the inner cavity of the mounting cabinet 1. A sliding plate 71 is slidably connected to the upper end of the primary slide rail 75. Several movable sliders 73 are arranged in an array at the lower end of the sliding plate 71. When the positioning support platform 4 needs to be loaded, the operator opens the cabinet door 5 and pulls the positioning support platform 4 outward from the mounting cabinet 1. The sliding plate 71 moves along the primary slide rail 75 with the positioning support platform 4. The several movable sliders 73 slide within the primary slide rail 75 and support the sliding plate 71, so that the movement direction of the sliding plate 71 is controlled by the sliding plate 71. To limit and reduce the possibility of swaying and jamming during the pulling of the positioning support platform 4, the width of the movable slider 73 on the front side is smaller than the width of the slot of the primary slide rail 75 and can slide out through the front slot of the primary slide rail 75. When the positioning support platform 4 is pulled forward to the loading position, the movable slider 73 on the front side can pass through the front slot of the primary slide rail 75, allowing the positioning support platform 4 to have a longer outward movement distance. This makes it easier for operators to place the aluminum single-panel frame on the positioning support platform 4 and to observe the fit between the edge of the frame and the positioning structure. Several guide posts 72 are fixedly connected in an array at the upper end of plate 71. Each guide post 72 has a buffer washer 721 fitted onto its lower outer surface. A baffle 74, used to block the primary slide rail 75, is slidably connected to the front of the inner cavity of the mounting cabinet 1 via a spring. The outer surfaces of the buffer washers 721 are slidably connected to the positioning support platform 4. The baffle 74, under the action of the spring, can block the movement of the primary slide rail 75, reducing the possibility of the primary slide rail 75 being excessively pulled out during the pulling process, thus ensuring that the positioning support platform 4 maintains a good limiting position when moving outwards for loading. In this state, the guide column 72 slides with the positioning support platform 4. When the positioning support platform 4 moves up and down under the drive of the lifting drive structure 2, the guide column 72 guides the vertical movement of the positioning support platform 4, reducing the lateral sway of the positioning support platform 4 during the lifting process. The buffer washer 721 can contact and buffer the positioning support platform 4 when it descends or resets, reducing the hard impact between the support platform and the structure below, reducing the possibility of the workpiece loosening due to vibration, and helping to maintain a smooth fit between the guide column 72 and the positioning support platform 4.

[0023] For further details, please refer to [link / reference]. Figure 4The lifting drive structure 2 includes a mounting plate 21 installed on the bottom wall of the inner cavity of the mounting cabinet 1. A sliding cavity 26 communicating with the inner cavity of the mounting cabinet 1 is opened on the side of the mounting plate 21 near the positioning support platform 4. A lifting platform 24 is slidably connected to the inner surface of the sliding cavity 26. A screw 23 is threadedly connected to the middle of the inner surface of the lifting platform 24. A drive motor 22, which drives the screw 23 to rotate, is fixedly connected to the upper end of the mounting plate 21. T-shaped plates 25, which are slidably connected to the sliding cavity 26, are symmetrically fixed to the end of the lifting platform 24 near the positioning support platform 4. The upper end of the horizontal portion of the T-shaped plates 25 overlaps with the lower end of the positioning support platform 4. After the aluminum single-panel frame is initially positioned, the control cabinet 6 controls the drive motor 22 to start. The drive motor 22 drives the screw 23 to rotate. The screw 23, through its threaded engagement with the lifting platform 24, drives the lifting platform 24... 4. The lifting platform 24 moves up and down along the sliding cavity 26. The sliding cavity 26 guides and limits the lifting platform 24, so that the movement direction of the lifting platform 24 is consistent with the lifting direction of the positioning support platform 4. When the lifting platform 24 moves, it supports the positioning support platform 4 through the T-shaped plate 25. The T-shaped plates 25, which are symmetrically arranged at the front and rear, overlap with the lower end of the positioning support platform 4, which can make the positioning support platform 4 more evenly stressed during lifting and reduce the tilt caused by single-point lifting. The positioning support platform 4 is also vertically guided by the guide column 72, so the aluminum single panel frame can be smoothly sent to the height of the welding positioning structure 3. The screw 23 transmission method makes the rising and falling process of the positioning support platform 4 have good continuity, which makes it easier for the workpiece to gradually approach or move away from the welding area, and also reduces the disturbance to the already positioned state when manually lifting the aluminum single panel frame.

[0024] During operation of this embodiment, the cooperation between the guide structure 7 and the positioning support platform 4 allows the aluminum single-panel frame to be loaded outside the mounting cabinet 1 and then smoothly pushed into the welding area. The first-level slide rail 75, the sliding plate 71, and the movable slider 73 together restrict the pulling direction. The baffle 74 reduces the excessive outward movement of the first-level slide rail 75. The guide column 72 and the buffer washer 721 provide vertical guidance and buffer support during lifting. The drive motor 22 in the lifting drive structure 2 drives the screw 23 to drive the lifting platform 24 to move along the sliding cavity 26, and the T-shaped plate 25 supports the positioning support platform 4, so that the workpiece maintains good load-bearing stability and positional continuity when transitioning from the loading position to the welding positioning structure 3.

[0025] Example 2: Based on Example 1, this example further provides a clamping structure and a side plate positioning assembly 45 on the positioning support platform 4, which are used for edge limiting, elastic clamping and side plate support of the aluminum single-panel frame. Specifically, the aluminum single-panel frame is clamped at the edge by the cooperation of the fixed stop 41 and the sliding block 42 on the positioning support platform 4. The fixed stop 41 provides a reference for the abutment, and the spring limit rod 43 slides in the positioning plate 44 and pushes the sliding block 42 to abut the workpiece, so that the clamping process has elastic compensation capability. The anti-slip strips increase the contact friction and reduce the possibility of the frame slipping during the pulling, lifting and welding process. At the same time, the side plate positioning assembly 45 uses the fixed stop 451 and the sliding block 452 to form double support for the side plate. The connecting block 453 moves along the limit guide rail 454 and compresses the compression spring 455, so that the sliding block 452 keeps rebounding and abutting, thereby enhancing the vertical support and edge fitting stability of the side plate and reducing the deformation caused by the side plate opening outward, tilting and rigid clamping.

[0026] For further details, please refer to [link / reference]. Figure 5 The positioning support platform 4 has four fixed blocks 41 fixedly connected in a rectangular arrangement on its upper end. Two fixed blocks 41 on the same side are opposite each other. The positioning support platform 4 also has four positioning plates 44 fixedly connected in a rectangular arrangement on its upper end. Spring limiting rods 43 are symmetrically slidably connected to the inner surfaces of the four positioning plates 44. Two spring limiting rods 43 installed on the same positioning plate 44 are fixedly connected to a sliding block 42 on the side away from the fixed blocks 41. Anti-slip stripes are provided on the side of each of the four fixed blocks 41 opposite to the adjacent sliding block 42. Straight sliding grooves 46 are symmetrically provided on both the front and rear sides of the upper end of the positioning support platform 4. Side plate positioning components 45 are symmetrically provided on the front and rear sides of the upper end of the positioning support platform 4 and are slidably connected to the two straight sliding grooves 46 on the same side to support the side plates. After the aluminum single-panel frame is placed on the positioning support platform 4, the four fixed blocks 41 provide abutment reference for the corresponding edges of the aluminum single-panel frame. The sliding block 42 is supported by the elastic force of the spring limiting rods 43. The aluminum panel frame moves downward towards the fixed stop 41, thereby clamping the aluminum panel frame between the fixed stop 41 and the sliding block 42. The positioning plate 44 restricts the sliding direction of the spring limit rod 43, so that the clamping action of the sliding block 42 is carried out in the set direction. The spring limit rod 43 can generate adaptive extension and contraction during clamping, so that the sliding block 42 can adapt to the small size differences and edge assembly gaps of the aluminum panel frame, reducing the local force concentration caused by rigid clamping. The anti-slip stripes on the opposite surfaces of the fixed stop 41 and the sliding block 42 can increase the friction between the clamping surface and the aluminum panel frame, so that the aluminum panel frame is not easy to slip during the pulling, lifting and subsequent welding of the positioning support platform 4. The straight slide groove 46 provides installation and sliding space for the side plate positioning assembly 45. The side plate positioning assembly 45 can support and limit the side plate of the aluminum panel frame, so that the bottom, edge and side plate of the frame are constrained, providing a basis for maintaining the shape of the frame during subsequent welding.

[0027] For further details, please refer to [link / reference]. Figure 6The side panel positioning assembly 45 includes a fixed stop block 451 fixedly connected to the upper end of a fixed stop block 41. Limiting guide rails 454 are fixedly connected to the inner surfaces of two straight sliding grooves 46 on the same side. Connecting blocks 453 are slidably connected to the inner surfaces of the two limiting guide rails 454. Sliding blocks 452 are fixedly connected to the upper ends of the two connecting blocks 453 and are slidably connected to the upper ends of the limiting guide rails 454. Compression springs 455 abutting against the front end of the connecting blocks 453 are fixedly connected to the inner surfaces of the two limiting guide rails 454. After the side panel of the aluminum single panel frame is placed in the corresponding position, the fixed stop block 451 abuts against one side of the side panel, and the sliding block 452 elastically abuts against the other side of the side panel. When the side plate pushes the second sliding block 452, the second sliding block 452 drives the two connecting blocks 453 to move along the corresponding limiting guide rails 454. During the movement of the connecting block 453, the compression spring 455 is compressed. The compression spring 455 generates a rebound force and pushes the second sliding block 452 to keep it in contact with the side plate through the connecting block 453. The limiting guide rails 454 can restrict the movement direction of the connecting blocks 453, so that the second sliding block 452 is not easy to tilt when it abuts the side plate. The two connecting blocks 453 jointly support the second sliding block 452, so that the sliding block... The force distribution of the second 452 on the side plate is relatively uniform. After the second fixed block 451 and the second sliding block 452 cooperate, the side plate can maintain a good vertical support state on the positioning support platform 4. The elastic compensation of the compression spring 455 can adapt to the small changes in the thickness or assembly position of the side plate, reducing the deformation of the side plate after being rigidly pressed. When the positioning support platform 4 is pulled out, pushed back or raised and lowered, the side plate positioning component 45 continuously supports the side plate, which helps to reduce the possibility of the side plate opening outward, tilting or separating from the frame body.

[0028] Example 3: Based on Example 2, this example further includes a welding positioning structure 3, a welding guide rail 33, a clamping arm 339, and a positioning auxiliary component 34, which are used to move and weld the aluminum single-panel frame in the welding area and to provide supplementary positioning. Specifically, the aluminum single-panel frame is supplemented and limited in the welding area by the cooperation of the welding positioning structure 3 and the positioning auxiliary component 34. The connecting plate 31 supports the welding guide rail 33, so that the workpiece is kept in a restricted state when the welding robot arm 32 moves along the guide groove 332 with the mounting seat 333 and the electric trolley 334. The cable 335 links the cross slider 337 and the clamping arm 339 to abut against the side plate. The damping ring 338 cooperates with the cross slide 336 to ease the clamping action. The limiting frame 342, the second compression spring 347, the telescopic limiting rod 348, the push block 341, the second connecting rod 346, the hinge seat 345 and the first connecting rod 344 further form a flexible abutment, thereby reducing the outward movement of the side plate, the corner warping and the positional changes during welding.

[0029] For further details, please refer to [link / reference]. Figure 7The welding positioning structure 3 includes four rectangularly distributed connecting plates 31, each fixedly connected to a mounting plate 21 on the same side. A welding guide rail 33 is fixedly connected to all four connecting plates 31. A welding robotic arm 32 is mounted on the upper end of the welding guide rail 33, and a plasma welding torch for welding aluminum single-panel frames is fixedly mounted on the arm of the welding robotic arm 32. A positioning auxiliary component 34 for positioning the aluminum single-panel frames is mounted on an auxiliary positioning support platform 4 at the lower end of the welding guide rail 33. The four connecting plates 31 support the welding guide rail 33 from different positions on the rectangular plates 331, allowing the welding guide rail 33 to be positioned above the positioning support platform 4. When the positioning support platform 4 rises under the drive of the lifting structure 2, the aluminum single-panel frame enters below the welding guide rail 33. In the welding area, the positioning auxiliary component 34 first cooperates with the aluminum single-panel frame and provides auxiliary positioning, so that the aluminum single-panel frame is subject to supplementary constraints from above and side before welding. The welding robot arm 32 is set on the upper end of the welding guide rail 33 and drives the plasma welding gun to approach the welding position of the aluminum single-panel frame through the rotating arm. Since the aluminum single-panel frame is supported between the positioning support platform 4 and the positioning auxiliary component 34, the welding robot arm 32 can complete the welding at the corresponding position in a relatively fixed state of the workpiece, reducing the edge misalignment caused by frequent workpiece movement. The welding positioning structure 3 also undertakes the functions of moving and installing the welding robot arm 32 and assisting in the pre-welding positioning of the workpiece, so that the welding action and the positioning action are coordinated in the installation cabinet 1, which facilitates the continuous completion of welding processing by the equipment.

[0030] For further details, please refer to [link / reference]. Figure 8 The welding guide rail 33 includes a rectangular plate 331 fixedly connected to the connecting plate 31. A guide groove 332 is provided at the upper end of the rectangular plate 331. An electric trolley 334 is movably mounted on the inner surface of the guide groove 332. A mounting seat 333 for mounting the welding robot arm 32 is fixedly connected to the upper end of the electric trolley 334. Cables 335 are symmetrically fixedly connected to the lower end of the electric trolley 334. The cables 335 are rectangularly distributed and pass through the inner cavity of the rectangular plate 331 and slide in the inner cavity of the rectangular plate 331. The rectangular plate 331 is fixed between four connecting plates 31 and is used to support the guide groove 332, the electric trolley 334 and the welding robot arm 32. When the control cabinet 6 controls the electric trolley 334 to run, the electric trolley 334 moves along the guide groove 332. The guide groove 332 limits the running path of the electric trolley 334, so that the electric trolley 334 drives the mounting seat 333 and the welding robot arm 32 to different welding positions of the aluminum single-panel frame. Mounting base 333 provides a connection base for welding robotic arm 32, enabling welding robotic arm 32 to move synchronously with electric trolley 334. During the movement of electric trolley 334, the cable 335 connected to its lower end slides in the inner cavity of rectangular plate 331. The cable 335 is arranged to pass through the inner cavity of rectangular plate 331, which can reduce the interference of exposed traction components on workpiece placement and the movement of welding robotic arm 32. The rectangularly distributed cable 335 can correspond to the clamping components at different positions below rectangular plate 331, so that when electric trolley 334 moves, it can drive the clamping structure below to produce corresponding actions. Thus, when welding robotic arm 32 moves to different welding positions, it provides matching restriction on the periphery of aluminum single plate frame, which helps to reduce the outward displacement of side plate due to force changes during welding.

[0031] For further details, please refer to [link / reference]. Figure 8 The welding guide rail 33 also includes cross grooves 336 at the four corners of the lower end of the rectangular plate 331. A cross slider 337 is slidably connected to the inner wall of the cross groove 336. A damping ring 338, fitted onto the outer surface of the cable 335, is fixedly connected to the middle of the inner surface of the cross slider 337. A clamping arm 339 for abutting against the side plate of the welding aluminum single-panel frame is fixedly connected to the lower end of the cross slider 337. When the electric trolley 334 drives the cable 335 to slide within the cavity of the rectangular plate 331, the cable 335 acts on the cross slider 337 through the damping ring 338, causing the cross slider 337 to move within the cross groove 336. The sliding fit between the cross groove 336 and the cross slider 337 guides and prevents deviation of the cross slider 337, reducing rotation of the cross slider 337 when pulled by the cable 335 or affected by the reaction force of the side plate. The damping ring 338, fitted onto the outer surface of the cable 335, can... The relative movement between the cable 335 and the cross slider 337 is damped, making the movement of the cross slider 337 and the clamping arm 339 smoother and reducing the sudden impact when the clamping arm 339 contacts the side plate of the aluminum single panel frame. After the clamping arm 339 approaches the side plate of the aluminum single panel frame with the cross slider 337, it abuts against the outside of the side plate and forms a constraint. The clamping arms 339 set at the four corners can constrain the side plate from different positions around the aluminum single panel frame. In conjunction with the fixed stop block 41, sliding block 42 and side plate positioning assembly 45 on the positioning support platform 4, as well as the positioning auxiliary assembly 34 at the lower end of the welding guide rail 33, the aluminum single panel frame can obtain multiple supports and limits in the welding area, reducing the side plate outward expansion, edge lifting and position changes during the welding process. The cooperation of the damping ring 338 and the cross slide 336 can also reduce the impact and shaking during the clamping action, making the abutment process of the clamping arm 339 against the side plate smoother.

[0032] For further details, please refer to [link / reference]. Figure 9 and Figure 10The positioning auxiliary component 34 includes a sliding guide rail 343 symmetrically fixed to the lower end of a rectangular plate 331. A limit frame 342 is slidably connected to the inner surface of the sliding guide rail 343. A compression spring 347, which is fixedly connected to the lower end of the rectangular plate 331, is fixedly connected to the upper end of the limit frame 342. A telescopic limit rod 348 is slidably connected to the inner surface of the limit frame 342. Push blocks 341 are fixedly connected to the piston rods on the left and right sides of the telescopic limit rod 348, respectively. A connecting rod 346 is symmetrically rotatably connected to the end of each push block 341 near the limit frame 342. The two connecting rods 346 on the same side are rotatably connected to a hinge seat 345. Each hinge seat 345 is rotatably connected to a connecting rod 344 rotatably connected to the adjacent end face of the limit frame 342. When the positioning support platform 4 drives the aluminum single-panel frame to rise to the welding area, the aluminum single-panel frame contacts the positioning auxiliary component 34, and the limit frame 342 moves along the sliding guide rail 343 under the action of the workpiece. Compression spring 347 is compressed and provides elastic support to limit frame 342, so that limit frame 342 and workpiece form flexible contact, reducing the excessive pressure of the upper positioning component on the side plate. After push block 341 is acted on by the side or adjacent structure of aluminum single panel frame, it drives the piston rod of telescopic limit rod 348 to extend and retract, and at the same time drives connecting rod 346 to rotate. Connecting rod 346 drives connecting rod 344 to swing through hinge seat 345, so that push blocks 341 on the left and right sides form linkage support. Telescopic limit rod 348 is used to adapt to the distance change in the left and right directions. Connecting rod 344, hinge seat 345 and connecting rod 346 are used to convert the force on push block 341 into swing and telescopic action, so that push block 341 can abut according to the actual position of aluminum single panel frame after entering the welding area. Compression spring 347 ensures that limit frame 342 can be reset after being compressed. Sliding guide rail 343 ensures that the movement direction of limit frame 342 is constrained. Thus, the positioning auxiliary component 34 can provide auxiliary restriction from above and left and right directions before welding the aluminum single-panel frame, and together with the positioning support platform 4, the fixed stop block 41, the sliding block 42, the side plate positioning component 45, and the clamping arm 339, it forms a multi-level limiting structure, so that the aluminum single-panel frame has support below, clamping at the edges, support on the side plates, and auxiliary abutment above, reducing the risk of displacement and deformation caused by heat, vibration, or movement of the robotic arm 32 during welding. After welding, the drive motor 22 drives the screw 23 to rotate in the opposite direction, and the lifting platform 24 drives the positioning support platform 4 to descend through the T-shaped mounting plate 25. The aluminum single-panel frame gradually separates from the positioning auxiliary component 34, and the limiting frame 342 is under the action of the compression spring 347. Upon resetting, push block 341, telescopic limit rod 348, connecting rod 2 346, hinge seat 345, and connecting rod 1 344 return to their positioning state. Clamping arm 339 releases its contact with the side plate as the cable 335 and cross slider 337 move. After the operator opens cabinet door 5, the positioning support platform 4 is pulled out along guide structure 7, and the welded aluminum single-panel frame can be removed for the next loading process. The entire operation process ensures that the aluminum single-panel frame undergoes basic clamping, side plate support, lifting and alignment, upper auxiliary limit, and circumferential clamping before entering the welding area. The movement connection between each structure is relatively clear, which can reduce the need for repeated manual correction and temporary support, making the equipment more suitable for continuous processing scenarios.
