Description

A laser welding platform and welding method for an intelligent trigger magnetic eyeglass frame hinge Technical Field

[0001] This invention relates to the field of intelligent welding technology, specifically to a laser welding platform and welding method for an intelligent trigger magnetic eyeglass frame hinge. Background Technology

[0002] As precision eyewear, eyeglass frames typically consist of a frame, a temple (the L-shaped component connecting the frame and temples), and temples. The welding of the temple to the frame is a crucial step in eyeglass manufacturing, as its precision directly affects the smoothness of temple opening and closing, the overall symmetry of the frame, and wearing comfort. With the development of laser welding technology, its advantages such as concentrated energy, small heat-affected zone, and aesthetically pleasing welds have led to its gradual replacement of traditional soldering or resistance welding, becoming the mainstream process in high-end eyeglass frame manufacturing.

[0003] Because the head of the mirror has special geometric features and needs to be welded to a predetermined position on the frame at a specific angle and position, the existing technology usually uses miniature pneumatic or electric grippers to directly grip a certain part of the head for positioning. However, the positioning accuracy of the grippers is highly dependent on the initial posture of the head during the transportation process. Any slight posture deviation will cause the welding point to be misaligned.

[0004] To overcome the shortcomings of mechanical grippers, magnetic clamping can be used to assist welding. Magnetic clamps have the advantages of uniform magnetic force distribution, no mechanical damage to the surface of the parts, and the ability to adapt to part size deviations within a certain range.

[0005] However, the laser welding process generates localized high temperatures. The heat is transferred to the welding head and clamping mechanism through heat conduction. For electromagnets, the temperature rise will cause their magnetic permeability to decrease, which in turn will cause the magnetic force to weaken. When the magnetic force weakens to the point that it is insufficient to overcome the weight of the welding head or the slight vibrations generated during the welding process, the welding head will loosen or shift, resulting in the welding point shifting or even welding failure. Summary of the Invention

[0006] The purpose of this invention is to provide a laser welding platform and welding method for an intelligent trigger magnetic eyeglass frame hinge, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0009] The machine tool and the support platform set on the machine tool are provided. A multi-directional translation mechanism is provided on the support platform. A bracket is connected to the multi-directional translation mechanism. A welding head is provided on the bracket. An infrared sensor is also provided on the machine tool to monitor the welding position.

[0011] A conveying assembly is symmetrically arranged on the machine base, and a conveyor belt is connected to the conveying assembly;

[0012] A lifting assembly is mounted on the machine platform. A support plate is connected to the lifting assembly. A slot is formed on the support plate. An electromagnet is mounted on the support plate. A clearance mechanism connected to the conveying assembly is mounted on the support plate.

[0013] A magnetic locking mechanism is provided on the support plate. A first sway plate and a second sway plate are connected to the magnetic locking mechanism in a symmetrical manner. The magnetic locking mechanism can suck the material placed on the conveyor belt into the slot and perform a positioning and locking action on the material through the first sway plate and the second sway plate.

[0014] As a further aspect of the present invention: the conveying assembly includes a lifting plate disposed on the machine base, a motor disposed on the lifting plate, and symmetrically distributed conveying rollers rotatably mounted on the lifting plate, one of the conveying rollers being connected to the output shaft of the motor, and the conveyor belt being sleeved on the conveying roller.

[0015] As a further embodiment of the present invention: the lifting assembly includes guide columns disposed on the bracket and symmetrically distributed, the support plate is slidably connected to the guide columns, a receiving plate is provided at the end of the guide columns, a cylinder is provided on the receiving plate, and the telescopic end of the cylinder is fixedly connected to the support plate.

[0016] As a further embodiment of the present invention: the yielding mechanism includes fixed plates disposed on the lifting plate and symmetrically distributed thereon, a movable rod slidably mounted on the fixed plate, a pressure plate disposed at the end of the movable rod, and a first spring sleeved on the movable rod, the two ends of the first spring abutting against the pressure plate and the fixed plate respectively.

[0017] As a further embodiment of the present invention: the yielding mechanism further includes an inclined plate disposed on the movable rod, and the support plate is provided with a limiting wheel that abuts against the inclined plate.

[0018] As a further embodiment of the present invention: the magnetic locking mechanism includes a support sleeve disposed on the support plate, and the support sleeve is rotatably connected to the first deflector plate and the second deflector plate;

[0019] It also includes a push assembly and a driven assembly disposed on the support plate and connected to the support sleeve.

[0020] As a further embodiment of the present invention: the pushing assembly includes a push rod slidably installed in the support sleeve, the end of the push rod is provided with a connecting plate, and a second spring is sleeved on the push rod, the two ends of the second spring respectively abutting against the support sleeve and the connecting plate.

[0021] As a further embodiment of the present invention: the driven component includes a sliding groove formed on the support plate and communicating with the slot, a sliding block is slidably installed in the sliding groove, a hinge rod and a connecting rod are hinged on the sliding block, the hinge rod is hinged to the connecting plate, and the connecting rod is symmetrically distributed and respectively hinged to the first deflecting plate and the second deflecting plate.

[0022] As a further embodiment of the present invention: the multi-directional translation mechanism includes a horizontal moving component disposed on the support platform, and a vertical moving component disposed on the horizontal moving component, the vertical moving component being connected to the bracket.

[0023] A laser welding method for a smart-triggered magnetic eyeglass frame hinge includes the following steps:

[0024] Step 1: Place the material to be welded on the conveyor belt, and under the action of the conveying assembly, move the material to the clamping position;

[0025] Step 2: The lifting component moves, controlling the support plate to move towards the conveyor belt. At the same time, the electromagnet is energized to generate magnetic force, driving the magnetic locking mechanism to move, causing the first and second sway plates to give way.

[0026] Step 3: The support plate will also drive the displacement mechanism to move, so that the material is no longer restricted. Under the action of magnetic force, the material is sucked into the slot, and under the action of the magnetic locking mechanism, the material is positioned and locked by the first and second deflecting plates.

[0027] Step 4: The lifting assembly lifts the material to the welding position via the support plate, and the material is welded under the action of the welding head.

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] This invention can achieve the effect of first magnetic attraction and then mechanical positioning and locking by changing the current of the electromagnet and cooperating with the magnetic attraction and locking mechanism. In the magnetic attraction and guidance stage, the controllable magnetic force generated by the electromagnet will quickly suck the head on the conveyor belt into the slightly larger slot with an extremely short stroke. Because the suction stroke is extremely short, the initial position deviation of the head in the slot is controlled within a very small range, realizing flexible and non-destructive acquisition of parts.

[0030] During the mechanical positioning and locking stage, by reducing the electromagnetic current, the first and second deflector plates are gradually reset under the action of the second spring. They then make rigid contact to push the clamp head to make a small displacement adjustment in the slot, so that it is precisely fitted with the two adjacent side walls of the slot. At the same time, the first and second limiting rings form a vertical limit on the clamp head from above, thereby ensuring clamping accuracy and stability.

[0031] During the reset process of the magnetic locking mechanism, the first and second sway plates retract inward symmetrically. After their sides contact the two sides of the head, the applied lateral thrust can automatically correct the slight angular deviation of the head in the slot, so that its two sides are tightly fitted with the adjacent inner sidewalls of the slot. When the first and second sway plates are fully reset to the initial position perpendicular to the side of the slot, the head is precisely aligned, and its spatial posture is consistent with the geometric reference of the slot. In this way, the equipment has a high tolerance for the initial posture deviation of the head during the conveying process, avoiding the problem of subsequent welding failure due to slight deviation in the position of the head.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0046] Please refer to Figures 1-11. In this embodiment of the invention, a laser welding platform for an intelligent trigger magnetic eyeglass frame hinge includes:

[0047] The machine base 1 and the support platform 25 set on the machine base 1 are provided. The support platform 25 is provided with a multi-directional translation mechanism. The multi-directional translation mechanism is connected to a bracket 26. The bracket 26 is provided with a welding head 27. An infrared sensor is also provided on the machine base to monitor the welding position.

[0048] Also includes:

[0049] A conveying assembly is symmetrically arranged on the machine base 1, and a conveyor belt 4 is connected to the conveying assembly;

[0050] A lifting assembly is mounted on the machine base 1. A support plate 13 is connected to the lifting assembly. A slot 1301 is formed on the support plate 13. An electromagnet 15 is mounted on the support plate 13. A clearance mechanism connected to the conveying assembly is mounted on the support plate 13.

[0051] A magnetic locking mechanism is provided on the support plate 13. The magnetic locking mechanism is connected to a first sway plate 17 and a second sway plate 18 that are symmetrically distributed. The magnetic locking mechanism can suck the material placed on the conveyor belt 4 into the slot 1301 and perform a positioning and locking action on the material through the first sway plate 17 and the second sway plate 18.

[0052] Specifically, the component to be welded to the eyeglass frame and temple is the headstock. Since the headstock is an irregular, L-shaped rod, direct mechanical clamping can easily lead to loosening. The depth of the slot 1301 is comparable to the thickness of the headstock, and the two adjacent sides of the slot 1301 fit the outer edge of the headstock. When welding is required, the frame can be clamped and fixed using a fixture. Simultaneously, the headstock to be welded can be placed on the conveyor belt 4. The conveyor assembly operates, transporting the headstock to the clamping position via the conveyor belt 4. Then, the electromagnet 15 is energized, generating magnetic force. Under the action of this magnetic force, the magnetic locking mechanism controls the first deflector plate 17 and the second deflector plate 18 to perform a yielding deflection action. At this time, the lifting assembly operates, moving the support plate 13 towards the conveyor belt 4. The magnetic force provided by the electromagnet 15 to the headstock gradually increases. In this state, the yielding mechanism acts as a barrier, ensuring that the headstock does not shift due to the magnetic force. When displacement occurs, and the support plate 13 descends to the set height, the distance between the head and the slot 1301 reaches a controllable range. At this time, the clearance mechanism is activated and the position lock of the head is released. Under the action of magnetic attraction, the head is quickly sucked into the slot 1301. Since the head's movement stroke is short, the position deviation of the head in the slot 1301 will not be too large. Subsequently, the current flowing through the electromagnet 15 is reduced, so the magnetic force is reduced. The magnetic locking mechanism will control the first deflection plate 17 and the second deflection plate 18 to reset. Under the action of the first deflection plate 17 and the second deflection plate 18, the head is positioned and locked. After locking is completed, the lifting component controls the head to be raised to the welding position and turns off the electromagnet 15. At the same time, the welding position is measured under the action of the infrared sensor to ensure that the laser focus coincides with the weld. At this time, the multi-directional translation mechanism controls the welding head 27 to perform welding processing on the head and the frame through the bracket 26.

[0053] Please refer to Figures 1, 2, 4, 5, and 7. The conveying assembly includes a lifting plate 2 mounted on the machine base 1. A motor 3 is mounted on the lifting plate 2. Conveying rollers 301 are symmetrically distributed and rotatably mounted on the lifting plate 2. One of the conveying rollers 301 is connected to the output shaft of the motor 3. The conveyor belt 4 is sleeved on the conveying roller 301.

[0054] Please refer to Figures 1, 2, 4, 5, and 8. The lifting assembly includes guide columns 10 that are symmetrically distributed on the bracket 1. The support plate 13 is slidably connected to the guide columns 10. A receiving plate 11 is provided at the end of the guide column 10. A cylinder 12 is provided on the receiving plate 11. The telescopic end of the cylinder 12 is fixedly connected to the support plate 13.

[0055] Please refer to Figures 4 and 7. The yielding mechanism includes fixed plates 5 symmetrically distributed on the lifting plate 2. A movable rod 6 is slidably mounted on the fixed plate 5. A pressure plate 7 is provided at the end of the movable rod 6. A first spring 9 is sleeved on the movable rod 6. The two ends of the first spring 9 abut against the pressure plate 7 and the fixed plate 5, respectively. The yielding mechanism also includes an inclined plate 8 disposed on the movable rod 6. A limiting wheel 14 that abuts against the inclined plate 8 is provided on the support plate 13.

[0056] In detail, since the frame is large and the headpiece needs to be welded to both sides of the frame, it is necessary to ensure that the frame is in a rigid clamping state. Therefore, a fixture can be installed on the machine tool 1 to directly clamp the frame. However, the headpiece is small in size and irregular in shape. If it is directly grasped by the robot arm, the headpiece is prone to displacement, resulting in the welding point of the headpiece being misaligned with the frame after the robot arm grasps it. Therefore, it is necessary to use magnetic attraction to guide it before mechanical positioning.

[0057] Please refer to Figure 9. The size of the slot 1301 is larger than the size of the head, and the depth of the slot 1301 is equivalent to the thickness of the head. The distance between the pressure plate 7 and the conveyor belt 4 is slightly larger than the thickness of the head. The movable rod 6 is provided with a fixing ring that abuts against the fixed plate 5.

[0058] In the initial state, under the action of cylinder 12, the support plate 13 is located at the end of the stroke on the side away from the conveyor belt 4. At this time, the limit wheel 14 and the inclined plate 8 are separated. In this state, the distance between the two pressure plates 7 is the smallest, that is, the distance between the pressure plate 7 and the fixed plate 5 is the largest. The extension of the first spring 9 in its natural state is greater than the maximum distance between the pressure plate 7 and the fixed plate 5. Therefore, the first spring 9 is in a pre-compressed state and always provides the pressure plate 7 with a thrust in the direction away from the fixed plate 5.

[0059] When clamping and welding the head is required, the head can be placed on the conveyor belt 4 with a fixed orientation. At the same time, the motor 3 works and drives the conveyor roller 301 to rotate, thereby driving the conveyor belt 4 to move smoothly. The conveyor belt 4 gradually transports the head placed on it with a fixed orientation to the clamping position, that is, the area that cooperates with the pressure plate 7. When the head moves to the bottom of the pressure plate 7, since the initial distance between the pressure plate 7 and the conveyor belt 4 is slightly greater than the thickness of the head, the head is restricted in the channel formed by the pressure plate 7 and the conveyor belt 4 and cannot be displaced in the vertical direction, thus ensuring the accurate positioning of the head in the clamping position.

[0060] Subsequently, cylinder 12 operates, pushing support plate 13 to move along the axis of guide column 10 towards the direction close to conveyor belt 4. At the same time, electromagnet 15 is energized and begins to generate magnetic force. Under the action of magnetic force, magnetic locking mechanism is activated, driving first deflector plate 17 and second deflector plate 18 to deflect outward and open, making room for the subsequent head to enter slot 1301 and avoiding interference with the head's adsorption process.

[0061] In the initial stage of the downward movement of the support plate 13, since the pressure plate 7 locks the position of the cylinder head and the distance between the electromagnet 15 and the cylinder head is large, the magnetic force generated is not enough to overcome the blocking effect of the pressure plate 7, and the cylinder head remains stationary. As the support plate 13 continues to move downward, the distance between the electromagnet 15 and the cylinder head gradually decreases, and the magnetic attraction force acting on the cylinder head gradually increases. At the same time, the limiting wheel 14 set on the support plate 13 gradually approaches and contacts the inclined surface of the inclined plate 8 set on the movable rod 6.

[0062] When the limiting wheel 14 is in contact with the inclined surface of the inclined plate 8, as the support plate 13 continues to move downward, the limiting wheel 14 slides along the inclined surface and applies a horizontal force to the inclined plate 8. This force overcomes the pre-compression force of the first spring 9 and pushes the movable rod 6 and the pressure plate 7 fixed thereto to move away from the fixed plate 5, so that the distance between the two pressure plates 7 gradually increases and the first spring 9 is compressed.

[0063] When the support plate 13 descends to the set height, that is, when the vertical distance between the slot 1301 and the head reaches the preset threshold, the pressure plate 7 just completely disengages from the head, releasing the position lock of the head. At this time, the distance between the electromagnet 15 and the head is small enough. Under the action of magnetic attraction, the head is quickly and smoothly sucked into the effective space of the slot 1301. Since the movement stroke of the head from release to suction is extremely short, its final position deviation in the slot 1301 is controlled within a very small range.

[0064] After the head is sucked into the slot 1301, the cylinder 12 begins to reverse, driving the support plate 13 to slowly rise and reset. At the same time, the current flowing through the electromagnet 15 is reduced, and the magnetic force is weakened accordingly, but a residual magnetic force is maintained that is sufficient to effectively attract the head. During the weakening of the magnetic force, the magnetic locking mechanism is activated, driving the first deflector plate 17 and the second deflector plate 18 to deflect inward and reset. After resetting, the first deflector plate 17 and the second deflector plate 18 contact the two sides of the head, pushing the head to make a slight displacement adjustment in the slot 1301, so that its two sides are tightly fitted with the two adjacent inner sidewalls of the slot 1301, thus completing the positioning and mechanical locking of the head.

[0065] When the support plate 13 is raised to the predetermined welding position, the cylinder 12 stops moving, and the head is stably held in the slot 1301. Its welding point is precisely aligned with the position to be welded on the frame. Subsequently, after the infrared sensor accurately measures and confirms the welding position, the multi-directional translation mechanism controls the welding head 27 to move directly above the weld seam through the bracket 26, and completes the welding process between the head and the frame.

[0066] Please refer to Figures 1, 2, 4-6, and 8-11. The magnetic locking mechanism includes a support sleeve 16 disposed on the support plate 13, which is rotatably connected to the first sway plate 17 and the second sway plate 18. It also includes a pushing assembly and a driven assembly disposed on the support plate 13 and connected to the support sleeve 16. The pushing assembly includes a push rod 19 slidably installed within the support sleeve 16, with a connecting plate 20 at its end, and a sleeved portion on the push rod 19. The second spring 21 has two ends that abut against the support sleeve 16 and the connecting plate 20, respectively. The driven component includes a sliding groove 1302 formed on the support plate 13 and communicating with the slot 1301. A sliding block 22 is slidably installed in the sliding groove 1302. A hinge rod 23 and a connecting rod 24 are hinged on the sliding block 22. The hinge rod 23 is hinged to the connecting plate 20. The connecting rod 24 is symmetrically distributed and is hinged to the first deflector plate 17 and the second deflector plate 18, respectively.

[0067] Furthermore, the connecting plate 20 is made of iron material, and the first deflecting plate 17 and the second deflecting plate 18 are respectively provided with a first limiting ring 1701 and a second limiting ring 1801, which are in contact with the end face of the support plate 13.

[0068] Please refer to Figures 6 and 9. In the initial state, the electromagnet 15 is de-energized. At this time, the distance between the connecting plate 20 and the support sleeve 16 is the largest. The extension of the second spring 21 in its natural state is greater than the maximum distance between the connecting plate 20 and the support sleeve 16. Therefore, the second spring 21 is in a pre-compressed state and always provides the connecting plate 20 with a thrust in the direction away from the support sleeve 16. Under the action of the connecting plate 20, the sliding block 22 is controlled by the hinge rod 23 to be located at the end of the stroke of the sliding groove 1302 near the support sleeve 16. The sliding block 22 will control the angle between the first deflector plate 17 and the second deflector plate 18 to be the smallest through the connecting rod 24. The first deflector plate 17 and the second deflector plate 18 are perpendicular to the two sides of the slot 1301.

[0069] When it is necessary to clamp the head, the cylinder 12 works, pushing the support plate 13 to move smoothly along the axis of the guide column 10 towards the direction of the conveyor belt 4. At the same time, the solenoid 15 is energized and begins to generate magnetic force. Since the connecting plate 20 is made of iron, the magnetic force generated by the solenoid 15 generates an axial attraction force on the connecting plate 20. This attraction force overcomes the pre-compression elastic force of the second spring 21 and pulls the connecting plate 20 towards the direction of the support plate 13.

[0070] The movement of the connecting plate 20 drives the hinge rod 23 hinged to it to move. The hinge rod 23 transmits the linear motion of the connecting plate 20 to the sliding block 22 through its hinge point with the sliding block 22, driving the sliding block 22 to slide along the slide groove 1302 on the support plate 13 and move away from the support sleeve 16. The movement of the sliding block 22 drives the two connecting rods 24 hinged to it to move synchronously. Since the connecting rods 24 are symmetrically distributed and are hinged to the first deflector plate 17 and the second deflector plate 18 respectively, the movement of the connecting rods 24 drives the first deflector plate 17 and the second deflector plate 18 to open outward around their rotational connection point with the support sleeve 16, so that the included angle between the first deflector plate 17 and the second deflector plate 18 gradually increases, forming a space above the slot 1301 that is sufficient to accommodate the head.

[0071] At the moment when the support plate 13 descends to the set height and the two pressure plates 7 move to completely separate from the head, the distance between the electromagnet 15 and the head is small enough, and the generated magnetic attraction force will quickly and smoothly pull the head into the slot 1301.

[0072] After the cylinder head is sucked into the slot 1301, the cylinder 12 begins to reverse its action, causing the support plate 13 to slowly rise and reset. At the same time, the current flowing through the electromagnet 15 is reduced, and the magnetic force is weakened accordingly. As the magnetic force decreases, the second spring 21 begins to release its stored elastic potential energy, pushing the connecting plate 20 and the connected hinge rod 23, sliding block 22, connecting rod 24, first deflector plate 17 and second deflector plate 18 to gradually reset.

[0073] During the reset process, the first deflector plate 17 and the second deflector plate 18 retract inward, and their side ends gradually come into contact with the two sides of the head inside the suction slot 1301. As the first deflector plate 17 and the second deflector plate 18 continue to reset, they apply a lateral thrust to the head, pushing the head to make a slight displacement adjustment within the slot 1301, so that its two sides gradually fit tightly against the two adjacent inner sidewalls of the slot 1301. When the first deflector plate 17 and the second deflector plate 18 are completely reset to their initial positions, that is, when they are perpendicular to the two sides of the slot 1301, the head is completely straightened and its position is precisely aligned with the slot 1301. At this time, the side ends of the first deflector plate 17 and the second deflector plate 18 fit tightly against the two sides of the head, forming a horizontal positioning lock for the head.

[0074] Since the depth of the slot 1301 is similar to the thickness of the head, when the head is completely placed into the bottom of the slot 1301, its upper and lower surfaces are flush with the surface of the support plate 13. The first limiting ring 1701 and the second limiting ring 1801 set on the first deflecting plate 17 and the second deflecting plate 18 are located just above the head, and work together with the end face of the support plate 13 to limit and lock the upper and lower sides of the head, preventing it from moving vertically during subsequent lifting and welding.

[0075] Please refer to Figure 9. At this time, the controllable electromagnet 15 is completely de-energized. Since the first deflector plate 17 and the second deflector plate 18 are tightly attached to the welding head in a vertical state, when the welding head is subjected to any external force, the force direction of the first deflector plate 17 and the second deflector plate 18 is perpendicular to its rotation axis. Therefore, no torque will be generated to cause it to deflect, ensuring the stable and reliable clamping of the welding head during the welding process. At the same time, since the electromagnet 15 is de-energized, the problem of magnetic force attenuation or disappearance caused by high welding temperature is completely avoided, eliminating the safety hazards that may exist if clamping is done solely by magnetic force, and ensuring the stability and reliability of the welding process.

[0076] Please refer to Figures 1-3. The multi-directional translation mechanism includes a horizontal moving component disposed on the support platform 25, and a vertical moving component disposed on the horizontal moving component. The vertical moving component is connected to the bracket 26.

[0077] Furthermore, the horizontal moving assembly includes a transverse lead screw, a transverse guide rail, and a transverse threaded sleeve mounted on the bearing platform 25, and a horizontal support platform set on the transverse threaded sleeve. A longitudinal lead screw, a longitudinal guide rail, and a longitudinal threaded sleeve are mounted on the horizontal support platform. The longitudinal threaded sleeve is connected to the vertical moving assembly. The vertical moving assembly includes a vertical support platform mounted on the longitudinal threaded sleeve. A vertical lead screw, a slide rail, and a vertical threaded sleeve are mounted on the vertical support platform. The vertical threaded sleeve is fixedly connected to the bracket 26.

[0078] A laser welding method for a smart-triggered magnetic eyeglass frame hinge includes the following steps:

[0079] Step 1: Place the material to be welded on the conveyor belt 4, and under the action of the conveying assembly, move the material to the clamping position;

[0080] Step 2: The lifting component moves, controlling the support plate 13 to move towards the conveyor belt 4. At the same time, the electromagnet 15 is energized to generate magnetic force, driving the magnetic locking mechanism to move, so that the first sway plate 17 and the second sway plate 18 give way.

[0081] Step 3: The support plate 13 will also drive the displacement mechanism to move, so that the material is no longer restricted. Under the action of magnetic force, the material is sucked into the slot 1301, and under the action of the magnetic locking mechanism, the material is positioned and locked by the first deflecting plate 17 and the second deflecting plate 18.

[0082] Step 4: The lifting assembly lifts the material to the welding position via the support plate 13, and the material is welded under the action of the welding head 27.
