Description

Technical Field

[0001] This application relates to the technical field of metal welding, and in particular to a suspended welding device and process. Background Technology

[0002] The condenser is the core heat exchange component of refrigeration equipment. It mainly consists of continuously bent copper tubes and metal strips welded to both sides of the copper tubes, forming a dense heat dissipation structure. The welding quality and efficiency of the metal strips and copper tubes directly determine the production efficiency and heat exchange performance of the condenser.

[0003] In existing technologies, the welding process between copper tubes and metal strips in condenser production generally employs horizontal welding equipment and corresponding processes. This process requires the copper tube to be placed horizontally on a special welding fixture, and the metal strips are manually laid evenly on one side of the copper tube segment by segment. After manual positioning, the fixture is transferred to the welding position of the spot welding machine, which then performs single-point welding on the connection points between the metal strips and the copper tube. After the metal strips on one side of the copper tube are welded, the copper tube needs to be rotated 180° manually or using a special fixture, and the above steps of manual strip laying, positioning, and welding are repeated to complete the welding of the metal strips on the other side of the copper tube. Due to the limitations of the horizontal structure, only one side of the copper tube can be welded, requiring two separate welding operations on both sides, resulting in poor welding consistency and low efficiency. Summary of the Invention

[0004] To enable simultaneous welding of metal strips on both sides of copper tubes and solve the problems of low efficiency and poor welding consistency in traditional horizontal welding, this application provides a suspended welding equipment and process.

[0005] The first objective of this invention is achieved through the following technical solution: A suspended welding device includes a device body, which comprises a hanger, a suspension station, a welding station, a traction assembly, a feeding mechanism, a lifting assembly, and a welding assembly. The hanger is used to suspend a workpiece; the traction assembly is used to pull the hanger to move between the suspension station and the welding station; the feeding mechanism is used to synchronously feed welding materials to both sides of the workpiece; the lifting assembly drives the hanger to move up and down at the welding station; two sets of welding assemblies are arranged correspondingly on both sides of the workpiece, each set of welding assemblies includes a welding drive and a welding head. The welding drive drives the welding head to translate to push the welding materials to both sides of the workpiece, and the welding head is used to weld and fix the welding materials to the workpiece. The translational welding action of the welding head is synchronized with the lifting and lowering movement of the hanger to achieve continuous welding of the workpiece.

[0006] By adopting the above technical solution, the workpiece is suspended on the hanger, and the traction component drives the hanger to move between the suspension station and the welding station. The feeding mechanism synchronously feeds welding materials to both sides of the workpiece, and the lifting component drives the hanger to rise and fall to realize the lifting and falling of the workpiece. The welding drive components on both sides of the workpiece drive the welding head to move horizontally and push and weld the welding materials. The horizontal welding action of the welding head and the lifting and falling action of the hanger are synchronized to achieve continuous welding. Compared with the existing technology, the feeding mechanism feeds materials synchronously from both sides of the workpiece, the welding head realizes bidirectional pushing and synchronous welding, and the welding action is linked with the lifting action of the workpiece to ensure continuous and consistent welding of welding materials on both sides of the workpiece during the lifting and falling process. This solves the problem of large welding deviation caused by the traditional workpiece needing to be flipped twice and welded in stages, and greatly improves welding efficiency.

[0007] Optionally, the suspension station is equipped with a lateral movement assembly, which includes a lateral movement drive, a front guide rail and a rear guide rail that slide with the hanger, and the lateral movement drive drives the front guide rail and the rear guide rail to move back and forth to alternately engage with the lifting assembly.

[0008] By adopting the above technical solution, the front and rear guide rails are moved back and forth by the transverse drive component, so that the front and rear guide rails can alternately dock with the lifting component. This enables the cyclic switching of the hanging fixture, reduces the waiting time for loading, further improves the continuous operation capability of the equipment, and improves the overall production efficiency.

[0009] Optionally, the lifting assembly includes a mounting rail, a lifting track, and a lifting drive component. The hanger can slide along the length of the mounting rail. The mounting rail is vertically slidably mounted on the lifting track. The lifting drive component drives the mounting rail to rise and fall along the lifting track to dock with the front guide rail or the rear guide rail.

[0010] By adopting the above technical solution, the hanger can slide along the mounting guide rail, which can be raised and lowered along the lifting track under the drive of the lifting drive component. This facilitates the precise adjustment of the workpiece height during the welding process to adapt to different welding position requirements. At the same time, it ensures stable docking between the mounting guide rail and the front or rear guide rail, improving the smoothness and positioning accuracy of the workpiece when switching between the suspension station and the welding station.

[0011] Optionally, the feeding mechanism is provided in two sets along both sides of the workpiece. The feeding mechanism includes a feeding component and a rotary feeding component. The feeding component includes an inclined rod and a hopper for storing welding materials. The inclined rod is inclinedly arranged below the welding materials so that the welding materials slide down the inclined rod onto the rotary feeding component under the action of gravity.

[0012] By adopting the above technical solution, the inclined bar is set so that the welding material slides down stably under the action of gravity, which can realize the synchronous automatic feeding of welding material on both sides of the workpiece, eliminating manual intervention. The continuous feeding of welding material is synchronized with the rotating feeding action of the rotating feeding component, ensuring that the welding material is accurately conveyed to both sides of the workpiece in a constant posture.

[0013] Optionally, the rotary feeding assembly includes a first wheel, a second wheel, a transmission belt, and a rotary drive component. Both the first wheel and the second wheel have grooves for supporting welding materials. The first wheel is used to receive welding materials on the inclined rod, and the second wheel is used to receive welding materials on the first wheel. The transmission belt is sleeved around the outer periphery of the first wheel and the second wheel. The rotary drive component drives the first wheel and the second wheel to rotate synchronously so that the welding materials are continuously fed to the welding position.

[0014] By adopting the above technical solution, the groove of the first wheel body receives the welding material that slides down the inclined rod, the groove of the second wheel body receives the welding material transmitted by the first wheel body, and the transmission belt ensures that the first wheel body and the second wheel body rotate synchronously, so that the welding material can be continuously and stably transported.

[0015] Optionally, the device body is also equipped with a support plate, which is located between the second wheel and the workpiece. The support plate is used to receive and limit the welding material output by the second wheel. The welding head is translated to push the welding material to the workpiece to be welded and to make the welding material fit with the workpiece.

[0016] By adopting the above technical solution, the support plate is used to receive and limit the welding material conveyed by the second wheel, which makes it easier to accurately push the stationary welding material to the welding position when the welding head moves laterally, and avoids the problem of incomplete welding or welding deviation caused by the position of the welding material.

[0017] Optionally, a front and rear limiting assembly is installed at the welding station. The front and rear limiting assembly includes a limiting member and a limiting drive member. The limiting drive member drives the limiting member to move closer to each other along the front and rear direction of the workpiece to limit the back and forth swing of the workpiece during the welding process.

[0018] By adopting the above technical solution, the limiting component approaches the workpiece from both the front and rear sides under the action of the limiting drive component. This not only does not affect the normal lifting and lowering action of the workpiece during the welding process, but also effectively limits the back-and-forth swaying of the workpiece during the lifting and lowering process, thereby ensuring the welding accuracy of the welding material.

[0019] Optionally, the support plate is fixedly installed on the limiting member, and the support plate moves closer to or further away from the workpiece synchronously with the limiting member. There are two support plates, which are respectively distributed on the left and right sides of the workpiece to limit the left and right displacement of the workpiece during the welding process.

[0020] By adopting the above technical solution, as the limiting component approaches the workpiece from both sides, the bearing plate moves synchronously to the left and right sides of the workpiece without affecting the lifting and lowering action of the workpiece, and also provides double limiting for the left and right positions of the workpiece. After welding is completed, the bearing plate moves away from the workpiece synchronously with the limiting component, and the workpiece can be smoothly transferred between the welding station and the suspension station.

[0021] The second objective of this invention is achieved through the following technical solution: A suspended welding process, using the aforementioned welding equipment to achieve double-sided welding of a workpiece, includes the following steps: S1: The workpiece is suspended on a hanger on the front guide rail; S2: The lateral drive unit drives the front and rear guide rails to move backward synchronously, so that the front guide rail aligns with the mounting guide rail, and the pulling assembly pulls the hanger along with the workpiece from the front guide rail to the mounting guide rail; S3: The lifting drive unit drives the mounting guide rail to rise as a whole, raising the workpiece to the preset welding height; S4: The limiting drive unit is activated, driving the limiting component to smoothly approach the workpiece in the front-back direction, and the bearing plate moves synchronously with the limiting component to both sides of the workpiece, completing the left-right and front-back limiting of the workpiece; S5: The feeding mechanisms on both sides of the workpiece are activated synchronously, and the first wheel and the second wheel rotate synchronously under the coordinated action of the rotating drive unit and the transmission belt, welding... Under the influence of gravity, the welding material slides down the inclined bar onto the first wheel. The second wheel receives the welding material conveyed by the first wheel, and the support plate lifts the welding material conveyed by the second wheel, ensuring that the welding material and the workpiece are at the same horizontal level. S6: The welding drive moves the welding head horizontally and pushes the welding material onto the surface of the workpiece. Then, the welding head welds and fixes the welding material to the workpiece, so that both sides of the workpiece are welded simultaneously. The welding action and the workpiece lifting action are synchronized and coordinated to achieve continuous welding of the workpiece. S7: After welding is completed, the limiting component and the support plate are reset, the mounting rail is lowered to the same height as the rear rail, the transverse drive operates in the opposite direction, and the rear rail is connected to the mounting rail. The pulling component pulls the fixture from the mounting rail to the rear rail, removes the welded workpiece, and completes a single cycle.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The feeding mechanism feeds materials synchronously from both sides of the workpiece, and the welding head pushes and welds in both directions. The welding action is linked with the lifting action of the workpiece, ensuring continuous and consistent welding of the welding materials on both sides of the workpiece during the lifting process. This solves the problem of large welding deviation caused by the traditional workpiece needing to be flipped twice and welded in stages, and greatly improves welding efficiency. 2. By using the transverse drive component to drive the front and rear guide rails to move back and forth, the front and rear guide rails can alternately dock with the lifting components, which can realize the cyclic switching of the hanging fixture, reduce the waiting time for loading, further improve the continuous operation capability of the equipment, and improve the overall production efficiency. 3. The fixture can slide along the mounting guide rail, which can be raised and lowered along the lifting track under the drive of the lifting drive component. This facilitates precise height adjustment of the workpiece during the welding process to adapt to different welding position requirements. At the same time, it ensures stable connection between the mounting guide rail and the front or rear guide rail, improving the smoothness and positioning accuracy of the workpiece when switching between the suspension station and the welding station.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] Example 1: A suspended welding device, reference Figure 1 and Figure 2The equipment includes a main body 1, which comprises a suspension station 111, a welding station 121, a hanger 131, a traction assembly 2, a lifting assembly 3, a feeding mechanism 4, and a welding assembly 5. The hanger 131 can slide smoothly between the suspension station 111 and the welding station 121. A copper pipe 141 is suspended on the hanger 131. The traction assembly 2 is located at the suspension station 111 and can pull the hanger 131 from the suspension station 111 to the welding station 121. After the copper pipe 141 is welded, the traction assembly 2 pulls the hanger 131 back from the welding station 121 to the suspension station 111, completing the cycle. The lifting assembly 3 is located at the welding station 121. After the traction assembly 2 pulls the hanger 131 to the welding station 121, the lifting assembly 5... Component 3 is adjusted to a height that matches the copper pipe 141, achieving precise docking of the copper pipe 141. The feeding mechanism 4 is set at the welding station 121 to synchronously feed metal strips 142 to both sides of the suspended copper pipe 141. Two sets of welding components 5 are set along both sides of the copper pipe 141. Each set of welding components 5 includes a welding drive component 511 and a welding head 521. The welding drive component 511 drives the welding head 521 to move radially along the copper pipe 141 to accurately push the metal strips 142 fed by the feeding mechanism 4 to the part of the copper pipe 141 to be welded, and simultaneously perform fusion welding. During the welding process, the lifting component 3 drives the hanger 131 to lift upward. The welding action of the copper pipe 141 and the lifting action work together to achieve continuous vertical welding of the copper pipe 141.

[0027] refer to Figure 1 and Figure 3 The hanger 131 includes a T-shaped plate 132 and a mounting plate 133. The T-shaped plate 132 is slidably fitted on the guide rail of the suspension station 111 and the guide rail of the welding station 121. A hook is installed on the T-shaped plate 132, and the copper pipe 141 is suspended on the hook. A bolt 134 is installed on the surface of the T-shaped plate 132. An L-shaped adjustment hole 135 is opened on the mounting plate 133. The bolt 134 and the L-shaped adjustment hole 135 are slidably fitted. After the copper pipe 141 is suspended in place, the mounting plate 133 can move to the right and then down along the L-shaped adjustment hole 135, so that the mounting plate 133 covers the hook. The copper pipe 141 is firmly limited between the mounting plate 133 and the T-shaped plate 132, effectively preventing the copper pipe 141 from shaking or falling off.

[0028] refer to Figure 1 and Figure 3The suspension station 111 is equipped with a transverse movement assembly 6, which includes a transverse movement drive 611, a front guide rail 612, and a rear guide rail 613. The front guide rail 612 and the rear guide rail 613 are arranged in parallel and fixedly connected. Hangers 131 are slidably installed on both the front guide rail 612 and the rear guide rail 613. The transverse movement drive 611 is fixedly installed on the equipment body 1. In this embodiment, the transverse movement drive 611 is preferably a cylinder. The transverse movement drive 611 can synchronously drive the front guide rail 612 and the rear guide rail 613 to move back and forth, so as to realize the coordinated displacement of the hangers 131 on the front guide rail 612 and the rear guide rail 613.

[0029] refer to Figure 1 and Figure 3 The traction assembly 2 has two sets, corresponding to the hangers 131 on the front guide rail 612 and the rear guide rail 613 respectively. Each traction assembly 2 includes a traction drive component (not shown in the figure), a slide rail 211, and a gripper 221. The slide rails 211 are located above the front guide rail 612 and the rear guide rail 613 respectively. The two slide rails 211 are fixedly connected by horizontal sheet metal parts, and the two slide rails 211 are fixedly connected to the front guide rail 612 and the rear guide rail 613 by vertical sheet metal parts, forming a frame that facilitates... The transverse drive 611 drives synchronous movement, and the gripper 221 slides back and forth along the slide rail 211. Driven by the traction drive, the gripper 221 located above the front guide rail 612 clamps the hanger 131 on the front guide rail 612 to complete the switching between the suspension station 111 and the welding station 121. The gripper 221 located above the rear guide rail 613 clamps the hanger 131 on the rear guide rail 613 to complete the switching between the suspension station 111 and the welding station 121. The two sets of traction components 2 work alternately.

[0030] refer to Figure 1 and Figure 3 The lifting component 3 includes a mounting guide rail 311, a lifting track 321, and a lifting drive (not shown in the figure). The hanger 131 can slide along the length of the mounting guide rail 311. The mounting guide rail 311 is vertically mounted on the lifting track 321. The lifting drive drives the mounting guide rail 311 to rise and fall vertically, so that the mounting guide rail 311 can be connected with the front guide rail 612 and the rear guide rail 613, realizing the smooth transfer of the hanger 131 between the suspension station 111 and the welding station 121.

[0031] refer to Figure 2 and Figure 4Two sets of feeding mechanisms 4 are symmetrically arranged along both sides of the copper tube 141. Each set of feeding mechanisms 4 includes a feeding component 411 and a rotary feeding component 421. The feeding component 411 includes a hopper 412 and an inclined rod 413. The hopper 412 is used to store the metal strip 142. One end of the inclined rod 413 rests on the edge of the hopper 412, and the other end extends into the hopper 412. The inclined rod 413 is inclined as a whole. Under the action of gravity, the metal strip 142 slides down along the length of the inclined rod 413 onto the rotary feeding component 421. The hopper 412 is equipped with an upper support rod 414 and a lower support rod 415 to support the inclined rod 413. The upper support rod 414 is used to support the higher end of the inclined rod 413, and the lower support rod 415 is used to support the higher end of the inclined rod 413. At the lower end of the support rod 413, the equipment body 1 is also equipped with a height adjustment cylinder 416. The output end of the height adjustment cylinder 416 is fixed to the upper support rod 414. The height of the upper support rod 414 is adjusted by extending and retracting the height adjustment cylinder 416, thereby changing the tilt angle of the rod 413 and precisely controlling the sliding speed and rhythm of the metal strip 142. A limiting ring 417 is fixedly sleeved on the outer periphery of the upper support rod 414. There are two rods 413 and four limiting rings 417, which are arranged in pairs and symmetrically distributed on both sides of the rod 413. They are used to constrain the axial displacement of the rod 413 along the upper support rod 414 and ensure that the rod 413 maintains a stable posture during the tilt angle adjustment process. The lower support rod 415 is fixedly connected to the hopper 412.

[0032] refer to Figure 2 and Figure 4 The rotary feeding assembly 421 includes a first wheel 422, a second wheel 423, a transmission belt 424, and a rotary drive component (not shown in the figure), which, in combination with... Figure 1 The first wheel 422 and the second wheel 423 are rotatably mounted on the equipment body 1. The outer diameter of the first wheel 422 is larger than that of the second wheel 423. The outer circumference of the first wheel 422 and the second wheel 423 are uniformly provided with a number of grooves 425. The central angle between two adjacent grooves 425 on the first wheel 422 is equal to the central angle between two adjacent grooves 425 on the second wheel 423. Since the outer diameters of the two wheels are different, the arc length spacing between the grooves 425 is correspondingly different. The first wheel 422 and the second wheel 423 rotate synchronously through the transmission belt 424, thereby ensuring that the grooves 425 are always accurately aligned at the junction of the first wheel 422 and the second wheel 423. The first wheel 422 is located at the end of the inclined rod 413 to receive the metal strip 142 that slides down from the inclined rod 413. The second wheel 423 is located near the copper tube 141. Multiple first wheels 422 and second wheels 423 are provided. The first wheels 422 and second wheels 423 are arranged alternately. After the metal strip 142 is received by the groove 425 of the first wheel 422, the second wheel 423 receives the metal strip 142 one by one as the first wheel 422 rotates, so as to realize the continuous feeding of the metal strip 142.

[0033] refer to Figure 2 and Figure 4 Two sets of front and rear limiting components 7 are installed at welding station 121, respectively located on both sides of copper tube 141. Each set of front and rear limiting components 7 includes a limiting element 711 and a limiting drive element 721. In this embodiment, the limiting drive element 721 is preferably a cylinder. The output end of the limiting drive element 721 is fixedly connected to the limiting element 711. During the welding process, the limiting elements 711 on both sides of copper tube 141 move towards copper tube 141 synchronously under the push of the corresponding limiting drive element 721, so as to avoid large swing of copper tube 141 in the front and rear direction. During the front and rear limiting, there is still a gap between the limiting element 711 and copper tube 141 to facilitate the upward movement of copper tube 141, so that the welded part moves upward and leaves welding station 121, and the next section to be welded enters welding station 121.

[0034] refer to Figure 2 and Figure 4 A support plate 712 is fixedly installed on the limiting component 711. The support plate 712 is located between the copper tube 141 and the second wheel body 423. The surface of the support plate 712 is higher than the lowest point of the second wheel body 423. The second wheel body 423 transfers the metal strip 142 to the support plate 712. The metal strip 142 falls to the support plate 712 under the action of gravity. The support plate 712 receives the metal strip 142 and provides it with a stable support surface. At the same time, there are two support plates 712 located on the left and right sides of the copper tube 141, which provide left and right direction limiting references for the copper tube 141 during the lifting and lowering process, ensuring the accuracy of the lifting and lowering trajectory of the copper tube 141, and thus ensuring the alignment accuracy between the welding position and the metal strip 142.

[0035] refer to Figure 2 and Figure 4 The welding drive component 511 is preferably a cylinder. Multiple welding heads 521 are provided and are evenly arranged along the width direction of the copper tube 141. The number of welding heads 521 corresponds one-to-one with the number of welding points on the copper tube 141. The metal strip 142 is located on the support plate 712. The welding drive component 511 pushes the welding head 521 to move horizontally, accurately pushing the metal strip 142 to the preset welding point position on the copper tube 141. Then, the welding head 521 presses the metal strip 142 and the copper tube 141 together and applies electricity for welding. After each metal strip 142 is welded, the lifting drive component drives the installation guide rail 311 to move vertically, so that the next welding point can be accurately aligned with the welding head 521. This cycle is repeated until all welding points are completed.

[0036] refer to Figure 2 and Figure 3 After welding is completed, the limiting member 711 moves away from the copper tube 141 under the drive of the limiting drive member 721. The bearing plate 712 and the limiting member 711 retract synchronously to make room for the copper tube 141 to be removed. The welding head 521 resets and then... Figure 1 The lifting drive component moves the installation guide rail 311 down to the initial position, and the lateral drive component 611 moves the rear guide rail 613 horizontally, aligning the installation guide rail 311 with the rear guide rail 613. The pulling component 2 corresponding to the rear guide rail 613 is activated, pulling the hanger 131 on the installation guide rail 311 onto the rear guide rail 613, whereby the worker removes the welded copper pipe 141.

[0037] The implementation principle of Embodiment 1 of this application is as follows: During operation, the copper tube 141 to be welded is first suspended on the hanger 131 of the front guide rail 612. The copper tube 141 is positioned to prevent detachment through the cooperation of the mounting plate 133 and the T-shaped plate 132. The transverse drive component 611 drives the front guide rail 612 to move horizontally and connect with the mounting guide rail 311 of the lifting component 3. The traction component 2 corresponding to the front guide rail 612 smoothly pulls the hanger 131 to the welding station 121. The lifting drive component drives the mounting guide rail 311. The lifting mechanism aligns the top of the copper tube 141, where it is to be welded, with the welding head 521. The front and rear limiting components 7 drive the limiting member 711 and the support plate 712 to move synchronously closer to the copper tube 141, completing the bidirectional limiting of the copper tube 141 in both the front-back and left-right directions. Simultaneously, the two feeding mechanisms 4 operate synchronously, causing the metal strip 142 in the hopper 412 to slide down the inclined bar 413 under gravity to the first wheel 422. Supported by the grooves 425 of the first wheel 422 and the second wheel 423, and rotating synchronously, the metal strip 142 is connected... The metal strip 142 is continuously and stably conveyed to the support plate 712; the welding drive components 511 of the two sets of welding components 5 synchronously push the welding head 521, accurately pushing the metal strip 142 on the support plate 712 to the surface of the copper tube 141, and the welding head 521 performs spot welding to fix the metal strip 142 and the copper tube 141; during the welding process, the lifting component 3 drives the installation guide rail 311 to move upward, so that the hanger 131 and the copper tube 141 are continuously lifted upward, and the welding action of the welding head 521 and the lifting action of the copper tube 141 are synchronized. Maintaining coordinated operation, continuous automated welding of copper tube 141 along the vertical direction is achieved. After welding is completed, the limiting component 711 and the bearing plate 712 are reset, the installation guide rail 311 is lowered and docked with the rear guide rail 613, and the traction component 2 corresponding to the rear guide rail 613 pulls the welded copper tube 141 back to the suspension station 111 for unloading. The front guide rail 612 simultaneously loads new copper tube 141, and then moves back to dock with the installation guide rail 311. The front guide rail 612 and the rear guide rail 613 alternately cycle.

[0038] Example 2: A suspended welding process, reference Figure 1 and Figure 3S1: During welding, the copper pipe 141 is suspended on the hanger 131 of the front guide rail 612. The mounting plate 133 moves along the L-shaped adjustment hole 135 and blocks the hook, completing the anti-detachment positioning of the copper pipe 141; S2: The transverse drive component 611 drives the front guide rail 612 and the rear guide rail 613 to move backward synchronously, so that the front guide rail 612 is connected with the mounting guide rail 311. The pulling component 2 corresponding to the front guide rail 612 pulls the hanger 131 and the copper pipe 141 from the front guide rail 612 to the mounting guide rail 311; S3: The lifting drive component drives the mounting guide rail 311 to rise along the lifting track 321, and then combined with Figure 2 S4: Subsequently, the limiting drive component 721 is activated, driving the limiting component 711 to smoothly approach the copper tube 141 in the front-back direction. The bearing plate 712 moves synchronously with the limiting component 711 to both sides of the copper tube 141, completing the left-right and front-back limiting of the copper tube 141 and preventing the copper tube 141 from shaking during the welding process. S5: The feeding mechanisms 4 on both sides of the copper tube 141 are activated synchronously. The first wheel 422 and the second wheel 423 rotate in the direction of the rotating drive component and the transmission mechanism. Under the coordinated action of the moving belt 424, the metal strip 142 slides down the inclined rod 413 onto the first wheel 422 under the action of gravity. The second wheel 423 receives the metal strip 142 conveyed by the first wheel 422, and the support plate 712 supports the metal strip 142 conveyed by the second wheel 423, ensuring that the metal strip 142 and the copper tube 141 to be welded are on the same horizontal plane; S6: The welding drive 511 drives the welding head 521 to translate and push the metal strip 142 onto the surface of the copper tube 141, and then the welding head 521... Metal strip 142 is welded and fixed to copper tube 141, so that both sides of copper tube 141 are welded simultaneously. While welding, the lifting drive component drives the installation guide rail 311 to rise slowly at a set speed. The translational welding action of welding head 521 is synchronized with the rising action of copper tube 141 to achieve continuous and uninterrupted welding of copper tube 141, ensuring uniform welding spacing and high welding consistency. After the welding of a single metal strip 142 is completed, copper tube 141 rises a certain distance to feed, push and weld the next metal strip 142. S7: After welding is completed, the limit drive 721 drives the limit component 711 and the support plate 712 to reset, releasing the limit on the copper pipe 141. The installation guide rail 311 descends to the same height as the rear guide rail 613. The transverse drive 611 operates in the opposite direction, connecting the rear guide rail 613 with the installation guide rail 311. The pulling component 2 corresponding to the rear guide rail 613 pulls the hanger 131 from the installation guide rail 311 to the rear guide rail 613, removing the welded copper pipe 141 and completing a single cycle.
