Description

Technical Field

[0001] The invention relates to the technical field of welding devices, in particular to an adjustable welding device. Background Art

[0002] Welding is a connection process that achieves atomic bonding of welded parts by applying heat, pressure, or both, with or without filler materials. Common methods include fusion welding, pressure welding, and brazing, which are widely used in manufacturing and other fields.

[0003] Traditional welding methods usually require manual hand-held welding guns to accurately control the welding position, angle and speed. The operation process is very labor-intensive and energy-consuming. With the development of industrial automation and manufacturing, continuous welding of workpieces is required in production to improve efficiency and quality. The welding device can automatically complete the welding operation based on preset programs, ensure the accuracy and stability of welding, and greatly improve production efficiency.

[0004] However, the existing welding devices have the following shortcomings: The traditional welding device places a welding ring between two workpieces, and then the high-frequency welding equipment quickly induction heats it and the surrounding area. The high temperature melts the welding ring to ensure that the liquid solder is accurately filled into the connection part of the workpiece. The specific shortcomings are as follows: 1) In order to achieve automated welding, traditional welding devices are generally complex in structure and require multiple components to work together to ensure complete functionality. However, this method greatly increases the cost and maintenance difficulty of the equipment, making the equipment purchase and subsequent operation and maintenance costs high and prone to failure. In addition, traditional welding devices are usually designed for specific workpieces. When the diameter and height of the workpiece change, the device cannot be flexibly adjusted, making it difficult to continue welding. The equipment must be replaced or significantly modified, which seriously affects production efficiency.

[0005] 2) In order to achieve automated welding, traditional equipment will be equipped with a conveying mechanism to transport the prepared workpiece to the welding area. However, traditional equipment is prone to deviation and shaking when transporting the workpiece to the welding position, which makes the connection position between the induction coil and the workpiece inaccurate during welding, and cannot ensure uniform heating, resulting in insufficient strength of the welding point and discontinuous welds. Summary of the invention

[0006] The object of the present invention is to provide an adjustable welding device, which realizes the reciprocating motion of the linkage plate through a gear rack transmission mechanism, thereby automatically transporting the clamped workpiece to the welding position, and with the help of the transmission of the threaded assembly, the welding height and the conveying distance can be flexibly adjusted to adapt to workpieces of different welding heights and diameters, so as to solve the problems raised by the above-mentioned background technology.

[0018] An adjustable welding device comprises the following steps: Step 1: When using, first connect the signal output end of the sensor assembly to the signal receiving end inside the electrical cabinet to ensure that the signal can be transmitted accurately. Before preparing for welding, it is necessary to adjust the height of the high-frequency welding machine according to the specific position of the welding workpiece. The staff first turns the handle, and the handle drives the first adjusting screw to rotate. Since the outer wall of the first adjusting screw is threadedly connected to the inner wall of the first thread groove, rotating the first adjusting screw can make the L-shaped lifting plate move up and down in the vertical direction. The movement of the L-shaped lifting plate drives the height of the high-frequency welding machine to be adjusted until the telescopic end of the first electric push rod is down. When it is lowered to the limit position, the height of the high-frequency coil of the high-frequency welding machine can just reach the welding position of the workpiece. In addition, it is necessary to adjust the position of the first movable rod according to the diameter of the workpiece. The staff rotates the first knob to make the first knob drive the second adjusting screw to rotate. Since the outer wall of the second adjusting screw is threadedly connected with the inner wall of the second thread groove, the rotation of the second adjusting screw can drive the third slider to move horizontally inside the third slide groove. The movement of the third slider drives the first movable rod to move synchronously to ensure that after the gear rotates half a circle, the linkage plate can just drive the workpiece to the bottom of the high-frequency coil of the high-frequency welding machine. Step 2: Adjust the width of the two limit plates again according to the diameter of the workpiece to prevent the workpiece from deflecting or slipping when being transported on the top of the belt conveyor. The staff rotates the second knob, which drives the bidirectional screw to rotate. The rotation of the bidirectional screw drives the two threaded blocks to move relative to each other, and the two limit plates are adjusted accordingly through the transmission of the connecting frame to ensure that the distance between the two limit plates matches the diameter of the workpiece, maintain the stability of the workpiece transportation, and complete the precise preparation before welding; Step 3: Subsequently, the staff places the circular workpieces that have been inserted into each other on the top of the belt conveyor, and sets the welding ring sleeve on the connection part of the two cylindrical workpieces. Then, multiple assembled workpieces are placed on the belt conveyor in sequence for transportation. When the workpiece moves to the bottom of the photoelectric sensor, the photoelectric sensor will immediately detect the position signal. After receiving the signal, the control system will immediately control the belt conveyor to stop conveying. At this time, the control system starts the third electric push rod, and its telescopic end pushes the moving plate to move. Since the moving plate is connected to the two sliding wedge blocks through the two seventh sliders, and the two inclined surfaces of the moving plate fit the inclined surfaces of the sliding wedge blocks, when the moving plate moves, it will drive the two seventh sliders to slide inside the corresponding sixth slide groove, and the two seventh sliders will further drive the two sliding wedge blocks to move toward each other inside the fifth slide groove, and the two sliding wedge blocks will drive the two clamping plates to move synchronously, so as to achieve a stable clamping of the workpiece; Step 4: When the workpiece is firmly clamped, the control system immediately starts the first electric push rod, and the telescopic end of the first electric push rod drives the sliding frame and the rack to descend synchronously through the connecting plate, and the descending movement of the sliding frame drives the high-frequency welding machine to move downward. At the same time, the movement of the rack drives the gear to rotate. Since the eccentric end of the gear is provided with a first movable rod, and the outer wall movable sleeve of the first movable rod is provided with a connecting rod, the rotational movement of the gear can be converted into the reciprocating motion of the connecting rod, and the connecting rod then drives the linkage plate to reciprocate through the second movable rod. When the telescopic end of the first electric push rod reaches its limit position, the rack has driven the gear to rotate half a circle. At this time, the linkage plate just moves from the limit position on one side to the limit position on the other side, and the movement of the linkage plate also drives the clamping mechanism on its top to move synchronously, so that the welding part of the clamped workpiece accurately reaches the high-frequency coil welding position of the high-frequency welding machine, thereby completing the welding process; Step 5: After welding is completed, the control system starts the third electric push rod again, and its telescopic end pushes the movable plate to reset, causing the two clamps to separate. At this time, the welded workpiece falls naturally by its own gravity, and slides smoothly into the collection box through the guiding effect of the guide plate. Subsequently, the control system starts the third electric push rod, and its telescopic end drives the support plate and the clamping assembly to move smoothly to one side through the push block, effectively preventing the two clamps from accidentally pushing the workpiece that is re-conveyed to the extreme position by the belt conveyor during the resetting process. Subsequently, the control system starts the telescopic ends of the first electric push rod and the third electric push rod in an orderly manner to perform the resetting operation, ensuring that the welding assembly and the clamping mechanism can return to the initial position, and then performs the next round of welding processing according to the above steps. According to this pre-set automated process, the device can continuously perform welding processing for multiple workpieces of the same batch to ensure the continuity and stability of the production process.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets an adjustment mechanism, and when a motor is used to drive a high-frequency welding machine to perform welding operations, the reciprocating motion of the linkage plate is realized through a gear rack transmission mechanism, thereby automatically conveying the clamped workpiece to the welding position, and with the help of the transmission of the threaded assembly, the welding height and conveying distance can be flexibly adjusted to adapt to workpieces of different welding heights and diameters. In this way, the structure of the welding equipment is simplified, and the material is automatically delivered to the welding position during the welding process without the need for an additional power device, thereby greatly reducing the equipment cost and maintenance difficulty, and reducing the failure rate. In addition, the flexible adjustment of the welding height and conveying distance enhances the flexibility and applicability of the equipment, thereby improving production efficiency.

[0020] 2. The present invention sets a clamping mechanism and utilizes an electric push rod to drive two clamping plates to clamp the workpiece, thereby ensuring that the workpiece maintains a high degree of stability and position accuracy during the process of being transported to the welding assembly, preventing movement or offset during welding, thereby ensuring welding quality. In addition, this clamping method can firmly clamp workpieces of different diameters, thereby improving the versatility and adaptability of the equipment.

[0021] 3. The present invention sets a conveying mechanism and utilizes a threaded transmission mechanism to adjust the distance between the two limit plates, thereby ensuring that the workpiece is effectively limited when being conveyed at the top of the belt conveyor, effectively preventing the workpiece from shaking or shifting during the conveying process, thereby ensuring the stability of the conveying and the welding accuracy.

By using the threaded transmission mechanism, the L-shaped lifting plate 107 and the high-frequency welding machine 108 can be flexibly moved up and down in the vertical direction. This adjustment ensures that when the first electric push rod 117 drives the sliding frame 104 to descend to the limit position, the high-frequency coil can accurately reach the welding position of the workpiece for efficient brazing. Next, according to the diameter of the workpiece, the position of the first movable rod 125 needs to be further adjusted.

After the adjustment is completed, the workpiece is firmly clamped by the clamping mechanism 2, and then the first electric push rod 117 is started, and its telescopic end drives the sliding frame 104 and the rack 115 to move downward. Under the meshing transmission of the gear 118 and the rack 115, the connecting rod 130 drives the linkage plate 132 to approach the high-frequency welding machine 108, and after the above adjustment, the linkage plate 132 can smoothly drive the fixed workpiece to move to the bottom of the high-frequency coil, and the welding part is just located in the high-frequency welding heating area.

An L-shaped fixing rod 311 is fixedly installed on the top of the belt conveyor 301, and a photoelectric sensor 312 is fixedly installed on the top of the L-shaped fixing rod 311.

[0033] The effect achieved by the entire embodiment 3 is as follows: during use, it is first necessary to rotate the second knob 306 according to the diameter of the workpiece to be welded. The second knob 306 will drive the bidirectional screw rod 304 to start rotating, thereby driving the two threaded blocks 305 to move closer to or farther away from each other along the direction of the screw rod. The two threaded blocks 305 can synchronously push or pull the corresponding limit plates 310 to move through their respective connected connecting frames 307. Through this adjustment mechanism, the distance between the two limit plates 310 can be accurately adjusted to ensure that the workpiece can be limited when being transported at the top of the belt conveyor 301. This limiting effect can effectively prevent the workpiece from shaking or deviating during transportation, thereby ensuring that the workpiece can be stably and accurately transported to the clamping position.

[0034] The working principle of the whole mechanism is as follows: in the preparation stage before welding, first ensure that the signal output end of the photoelectric sensor 312 is connected to the signal receiving end inside the electrical cabinet 139. At the same time, the power supply and control end of all other electrical components must also be properly connected to the corresponding control module inside the electrical cabinet 139. The control module and data acquisition module integrated in the electrical cabinet 139 are all existing technologies. Next, connect the power supply of the device to the external power supply to ensure that all electrical components can be powered normally and started smoothly. Subsequently, according to the welding height of the welding workpiece, the staff needs to adjust the height of the high-frequency welding machine 108. The staff drives the first adjusting screw 110 to rotate by turning the handle 112, and then the first adjusting screw 110 and the second adjusting screw 110 are connected. The threaded fit of the first threaded groove 109 enables the L-shaped lifting plate 107 and the high-frequency welding machine 108 to achieve precise up and down movement in the vertical direction, ensuring that when the telescopic end of the first electric push rod 117 drops to its limit position, the high-frequency coil of the high-frequency welding machine 108 can just reach the welding position of the workpiece. In addition, the position of the first movable rod 125 needs to be adjusted according to the diameter of the workpiece. The staff drives the second adjusting screw 127 to rotate by rotating the first knob 128, and then the third slider 124 is horizontally moved inside the third slide groove 123 through the threaded fit of the second adjusting screw 127 and the second threaded groove 126. The movement of the third slider 124 drives the first movable rod 125 to move synchronously to ensure that when the gear 118 rotates halfway, the first movable rod 125 can move horizontally. After the circle, the linkage plate 132 can just drive the workpiece to the bottom of the high-frequency coil of the high-frequency welding machine 108. Next, the staff needs to adjust the width of the two limit plates 310 according to the diameter of the workpiece, and by rotating the second knob 306, the second knob 306 drives the bidirectional screw rod 304 to rotate, so that the two threaded blocks 305 move in opposite directions under the drive of the bidirectional screw rod 304. The movement of the two threaded blocks 305 is transmitted through the corresponding connecting frame 307, so that the two limit plates 310 adjust the spacing accordingly to ensure that the distance between them matches the diameter of the workpiece, thereby maintaining the stability of the workpiece during the transportation process. At this time, the staff places the circular workpieces that have been inserted into each other on the top of the belt conveyor 301, and sets the welding ring sleeves on the two The connecting part of the cylindrical workpiece is then continuously placed on the belt conveyor 301 for transportation. When the workpiece moves to the bottom of the photoelectric sensor 312, the photoelectric sensor 312 will immediately detect the position signal and trigger the control system to control the belt conveyor 301 to stop conveying. At the same time, the third electric push rod 211 is started. The telescopic end of the third electric push rod 211 pushes the moving plate 210 to move. Through the sliding cooperation of the two seventh sliders 209 and the two sixth slide grooves 208, the two sliding wedge blocks 206 move toward each other inside the fifth slide groove 205, thereby driving the two clamping plates 207 to move synchronously to achieve a stable clamping of the workpiece. Subsequently, the control system starts the first electric push rod 117.Its telescopic end drives the sliding frame 104 and the rack 115 to descend synchronously through the connecting plate 116, and the descending movement of the sliding frame 104 drives the high-frequency welding machine 108 to move downward. At the same time, the movement of the rack 115 drives the gear 118 to rotate, and then the rotation of the gear 118 drives the position of the first movable rod 125 to change. The change of the first movable rod 125 is driven by the transmission effect of the connecting rod 130, so that the second movable rod 131 drives the linkage plate 132 to reciprocate. When the telescopic end of the first electric push rod 117 reaches its limit position, the rack 115 has driven the gear 118 to rotate half a circle. At this time, the linkage plate 132 just moves from the limit position on one side to the limit position on the other side, and drives the workpiece clamped on its top to reach the bottom of the high-frequency coil welding, thereby completing the welding process. After completion, the control system starts the third electric push rod 211 again, and its telescopic end pushes the moving plate 210 to reset, causing the two clamping plates 207 to separate. At this time, the welded workpiece falls naturally by its own gravity, and slides smoothly into the collection box 138 through the guiding effect of the guide plate 137. Subsequently, the control system starts the telescopic end of the third electric push rod 211, and drives the support plate 201 and the clamping assembly to move smoothly to one side through the push block 202 to prevent the two clamping plates 207 from accidentally pushing and hitting the workpiece that is re-conveyed to the extreme position by the belt conveyor 301 during the reset process. Finally, the control system starts the telescopic end of the first electric push rod 117 and the third electric push rod 211 in an orderly manner to perform the reset operation, ensuring that the welding assembly and the clamping mechanism can return to the initial position and prepare for the next round of welding operations.

[0035] The present invention also provides a method for using the adjustable welding device, comprising the following steps: Step 1: When in use, first connect the signal output end of the sensor assembly to the signal receiving end inside the electrical cabinet 139 to ensure that the signal can be transmitted accurately. Before preparing for welding, it is necessary to adjust the height of the high-frequency welding machine 108 according to the specific position of the welding workpiece. The staff first turns the handle 112, and the handle 112 drives the first adjusting screw 110 to rotate. Since the outer wall of the first adjusting screw 110 is threadedly connected to the inner wall of the first thread groove 109, rotating the first adjusting screw 110 can make the L-shaped lifting plate 107 move up and down in the vertical direction. The movement of the L-shaped lifting plate 107 drives the height of the high-frequency welding machine 108 to be adjusted until the telescopic end of the first electric push rod 117 drops to the limit When the first movable rod 125 is in the right position, the height of the high-frequency coil of the high-frequency welding machine 108 can just reach the welding position of the workpiece. In addition, the position of the first movable rod 125 needs to be adjusted according to the diameter of the workpiece. The staff rotates the first knob 128 to make the first knob 128 drive the second adjusting screw 127 to rotate. Since the outer wall of the second adjusting screw 127 is threadedly connected with the inner wall of the second thread groove 126, the rotation of the second adjusting screw 127 can drive the third slider 124 to move horizontally inside the third slide groove 123. The movement of the third slider 124 drives the first movable rod 125 to move synchronously to ensure that after the gear 118 rotates half a circle, the linkage plate 132 can just drive the workpiece to the bottom of the high-frequency coil of the high-frequency welding machine 108. Step 2: Adjust the width of the two limit plates 310 again according to the diameter of the workpiece to prevent the workpiece from deviating or sliding when being transported on the top of the belt conveyor 301. The staff rotates the second knob 306, and the second knob 306 drives the bidirectional screw rod 304 to rotate. The rotation of the bidirectional screw rod 304 drives the two threaded blocks 305 to move relative to each other, and the two limit plates 310 are adjusted accordingly through the transmission of the connecting frame 307 to ensure that the distance between the two limit plates 310 matches the diameter of the workpiece, maintain the stability of workpiece transportation, and complete the precise preparation before welding; Step 3: Subsequently, the staff places the inserted circular workpieces on the top of the belt conveyor 301, and sets the welding ring on the connection part of the two cylindrical workpieces. Then, the multiple assembled workpieces are placed on the belt conveyor 301 in sequence for transportation. When the workpiece moves to the bottom of the photoelectric sensor 312, the photoelectric sensor 312 will immediately detect the position signal. After receiving the signal, the control system will immediately control the belt conveyor 301 to stop conveying. At this time, the control system starts the third electric push rod 211, and its telescopic end pushes the moving plate 21 0 is moved, because the moving plate 210 is connected to the two sliding wedge blocks 206 through the two seventh sliders 209, and the two inclined surfaces of the moving plate 210 are in contact with the inclined surfaces of the sliding wedge blocks 206, when the moving plate 210 moves, it will drive the two seventh sliders 209 to slide inside the corresponding sixth slide groove 208, and the two seventh sliders 209 will further drive the two sliding wedge blocks 206 to move towards each other inside the fifth slide groove 205, and the two sliding wedge blocks 206 will drive the two clamping plates 207 to move synchronously, so as to achieve a stable clamping of the workpiece; Step 4: When the workpiece is firmly clamped, the control system immediately starts the first electric push rod 117. The telescopic end of the first electric push rod 117 drives the sliding frame 104 and the rack 115 to descend synchronously through the connecting plate 116. The descending movement of the sliding frame 104 drives the high-frequency welding machine 108 to move downward. At the same time, the movement of the rack 115 drives the gear 118 to rotate. Since the first movable rod 125 is provided at the eccentric end of the gear 118, and the outer wall of the first movable rod 125 is movably sleeved with a connecting rod 130, the rotational movement of the gear 118 can be converted into a connecting rod. The connecting rod 130 reciprocates, and the connecting rod 130 further drives the linkage plate 132 to reciprocate through the second movable rod 131. When the telescopic end of the first electric push rod 117 reaches its limit position, the rack 115 has driven the gear 118 to rotate half a circle. At this time, the linkage plate 132 just moves from the limit position on one side to the limit position on the other side, and the movement of the linkage plate 132 also drives the clamping mechanism 2 on its top to move synchronously, so that the welding part of the clamped workpiece accurately reaches the high-frequency coil welding position of the high-frequency welding machine 108, thereby completing the welding process; Step 5: After welding is completed, the control system starts the third electric push rod 211 again, and its telescopic end pushes the movable plate 210 to reset, causing the two clamping plates 207 to separate. At this time, the welded workpiece falls naturally by its own gravity, and slides smoothly into the collection box 138 through the guiding effect of the guide plate 137. Subsequently, the control system starts the third electric push rod 211, and its telescopic end drives the support plate 201 and the clamping assembly to move smoothly to one side through the push block 202, effectively preventing the two clamping plates 207 from accidentally pushing the workpiece that is re-conveyed to the extreme position by the belt conveyor 301 during the resetting process. Subsequently, the control system starts the telescopic ends of the first electric push rod 117 and the third electric push rod 211 in an orderly manner to perform the resetting operation, ensuring that the welding assembly and the clamping mechanism 2 can return to the initial position, and then performs the next round of welding processing according to the above steps. According to this pre-set automated process, the device can continuously perform welding processing for multiple workpieces of the same batch to ensure the continuity and stability of the production process.

10. A method for using an adjustable welding device, using the adjustable welding device according to claim 9, comprising the following steps: S1: When in use, first connect the signal output end of the sensor assembly to the signal receiving end inside the electrical cabinet (139) to ensure that the signal can be transmitted accurately. Before preparing for welding, it is necessary to adjust the height of the high-frequency welding machine (108) according to the specific position of the welding workpiece. The staff first rotates the handle (112), and the handle (112) drives the first adjusting screw (110) to rotate. Since the outer wall of the first adjusting screw (110) is threadedly connected to the inner wall of the first thread groove (109), rotating the first adjusting screw (110) can make the L-shaped lifting plate (107) move up and down in the vertical direction. The movement of the L-shaped lifting plate (107) drives the height of the high-frequency welding machine (108) to be adjusted until the telescopic end of the first electric push rod (117) drops to the limit position. The height of the high-frequency coil of the high-frequency welding machine (108) can just reach the welding position of the workpiece. In addition, the position of the first movable rod (125) needs to be adjusted according to the diameter of the workpiece. The staff rotates the first knob (128) to make the first knob (128) drive the second adjusting screw (127) to rotate. Since the outer wall of the second adjusting screw (127) is threadedly connected to the inner wall of the second thread groove (126), the rotation of the second adjusting screw (127) can drive the third slider (124) to move horizontally inside the third slide groove (123). The movement of the third slider (124) in turn drives the first movable rod (125) to move synchronously, so as to ensure that after the gear (118) rotates half a circle, the linkage plate (132) can just drive the workpiece to the bottom of the high-frequency coil of the high-frequency welding machine (108); S2: The width of the two limit plates (310) is adjusted again according to the diameter of the workpiece to prevent the workpiece from deviating or sliding when being transported on the top of the belt conveyor (301). The staff rotates the second knob (306), and the second knob (306) drives the bidirectional screw rod (304) to rotate. The rotation of the bidirectional screw rod (304) drives the two threaded blocks (305) to move toward each other, and the two limit plates (310) are adjusted accordingly through the transmission of the connecting frame (307), ensuring that the distance between the two limit plates (310) matches the diameter of the workpiece, maintaining the stability of workpiece transportation, and completing the precise preparation before welding; S3: Subsequently, the staff places the circular workpieces that have been inserted into each other on the top of the belt conveyor (301), and sets the welding ring on the connection part of the two cylindrical workpieces. Then, a plurality of assembled workpieces are placed on the belt conveyor (301) in sequence for transportation. When the workpiece moves to the bottom of the photoelectric sensor (312), the photoelectric sensor (312) will immediately detect the position signal. After receiving the signal, the control system will immediately control the belt conveyor (301) to stop transportation. At this time, the control system starts the third electric push rod (211), and its telescopic end pushes the moving plate (210) to move. Since the movable plate (210) is connected to the two sliding wedge blocks (206) through the two seventh sliding blocks (209), and the two inclined surfaces of the movable plate (210) fit the inclined surfaces of the sliding wedge blocks (206), when the movable plate (210) moves, the two seventh sliding blocks (209) are driven to slide inside the corresponding sixth sliding groove (208), and the two seventh sliding blocks (209) further drive the two sliding wedge blocks (206) to move toward each other inside the fifth sliding groove (205), and the two sliding wedge blocks (206) drive the two clamping plates (207) to move synchronously, so as to achieve a stable clamping of the workpiece; S4: When the workpiece is firmly clamped, the control system immediately starts the first electric push rod (117). The telescopic end of the first electric push rod (117) drives the sliding frame (104) and the rack (115) to descend synchronously through the connecting plate (116). The descending movement of the sliding frame (104) drives the high-frequency welding machine (108) to move downward. At the same time, the movement of the rack (115) drives the gear (118) to rotate. Since the first movable rod (125) is provided at the eccentric end of the gear (118), and the outer wall of the first movable rod (125) is movably sleeved with a connecting rod (130), the rotational movement of the gear (118) can be converted into The connecting rod (130) reciprocates, and the connecting rod (130) drives the linkage plate (132) to reciprocate through the second movable rod (131). When the telescopic end of the first electric push rod (117) reaches its limit position, the rack (115) has driven the gear (118) to rotate half a circle. At this time, the linkage plate (132) just moves from the limit position on one side to the limit position on the other side. In addition, the movement of the linkage plate (132) also drives the clamping mechanism (2) on its top to move synchronously, so that the welding position of the clamped workpiece accurately reaches the high-frequency coil welding position of the high-frequency welding machine (108), thereby completing the welding process; S5: After the welding is completed, the control system starts the third electric push rod (211) again, and its telescopic end pushes the movable plate (210) to reset, causing the two clamping plates (207) to separate. At this time, the welded workpiece falls naturally by its own gravity, and slides smoothly into the collection box (138) through the guiding effect of the guide plate (137). Subsequently, the control system starts the third electric push rod (211), and its telescopic end drives the support plate (201) and the clamping assembly to move smoothly to one side through the push block (202), effectively preventing the two clamping plates (207) from accidentally pushing and hitting the workpiece that is re-conveyed to the extreme position by the belt conveyor (301) during the reset process. Subsequently, the control system starts the telescopic ends of the first electric push rod (117) and the third electric push rod (211) in an orderly manner to perform the reset operation, ensuring that the welding assembly and the clamping mechanism (2) can return to the initial position, and then performs the next round of welding processing according to the above steps.
