Description

Technical Field

[0001] This invention belongs to the field of electromechanical welding technology, and specifically relates to an automatic welding device for the installation and fixing of electromechanical facilities. Background Technology

[0002] In electromechanical engineering construction, the installation and fixing quality of electromechanical facilities directly determines the stability and safety of the overall project. Welding is the core process for installing and fixing electromechanical facilities, achieving the connection and fixation of components. In the welding of nuts for motor bases and plates, welding machines are mainly used to weld the nuts to the base material to achieve a tight connection. The welding machine adopts the principle of double-sided, double-point overcurrent welding. When welding the workpiece, the upper and lower electrodes apply pressure to the workpiece, forming a certain contact resistance under pressure. The welding current forms an instantaneous thermal fusion and circuit at the two contact resistance points, and the internal structure of the workpiece is not affected. This welding process has the advantages of high efficiency, reliability, and aesthetics.

[0003] In existing nut welding processes, to facilitate nut handling by robotic arms, the nut's protrusions are directly positioned downwards during transport, rubbing against the conveyor surface. This is particularly problematic in mass production, where the nut's transport trajectory is often long, easily leading to excessive wear, deformation, or end-face damage to the protrusions. This, in turn, affects the subsequent welding quality of the protrusions. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic welding device for installing and fixing electromechanical facilities that has a simple structure and a reasonable design in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: An automatic welding device for installing and fixing electromechanical facilities, comprising: The feeding mechanism and the conveying frame are provided. The discharge end of the feeding mechanism is connected to the inlet end of the conveying frame. The feeding mechanism is used to convey the welding nuts to be welded into the conveying groove of the conveying frame. A material turning mechanism, wherein the turning mechanism is used to turn the welding nuts being conveyed upright in the conveying trough to an inverted state; A clamping mechanism is used to move the flipped welding nut to the welding position; The welding mechanism, set on the workbench, is used to weld welding nuts onto the plates.

[0006] As a further optimization of the present invention, the welding nut includes a welding base, a welding protrusion, and a nut body. The welding base is fixedly provided at one end of the nut body, and the welding protrusion is provided at the end of the welding base away from the nut body. A threaded hole is opened at the axis of the nut body, and the threaded hole passes through the welding base. When the welding nut is in the welding position, the welding protrusion rubs against the plate. When the welding nut is in the upright position, the welding protrusion of the welding nut is arranged upward, and when the welding nut is in the inverted position, the welding protrusion of the welding nut is arranged downward.

[0007] As a further optimization of the present invention, the material turning mechanism includes a conversion frame, a pushing component, and a flipping component. The discharge end of the conveying frame is connected to the inlet end of the conversion frame. The conversion frame is provided with a conversion groove. The feeding mechanism is used to push the welding nuts in the conveying groove into the conversion groove. A conversion boss is provided on one side of the conversion groove. The side wall of the conversion boss facing the conversion groove is inclined. The welding nuts pushed into the conversion groove are inclinedly overlapped on the conversion boss. The pushing component is provided on the conversion frame and is located on the side of the conversion boss away from the conversion groove. The pushing component is used to push the welding nuts in the conversion groove forward. The flipping component is provided on the side of the conversion groove away from the conveying groove. The flipping component is used to flip the inclined welding nuts to an inverted state.

[0008] As a further optimization of the present invention, the propulsion assembly includes a propulsion drive assembly, a second rotation drive component, and a propulsion plate. The output end of the propulsion drive assembly is provided with a mounting base, and the second rotation drive component is mounted on the mounting base. The output end of the second rotation drive component is fixedly connected to the propulsion plate. The lower end of the propulsion plate has an arcuate protrusion. When the propulsion plate swings to the propulsion position under the drive of the second rotation drive component, the propulsion plate is located behind the first welding nut in the conversion groove, and the propulsion plate rubs against the side wall of the welding base of the welding nut. In this case, along the conveying direction of the welding nut in the conversion groove, the last welding nut in the conversion groove is considered as the first welding nut.

[0009] As a further optimization of the present invention, the flipping assembly includes a tray, a pressure plate, and a flipping drive assembly. The tray has an L-shaped structure and is used to receive the welding nut pushed in by the push plate. The output end of the flipping drive assembly is connected to the tray. The flipping drive assembly is used to drive the tray to swing until the welding nut abuts against the pressure plate, and the pressure plate swings from a vertical position to a horizontal position under the abutment of the welding nut. At this time, the welding nut is in an inverted state.

[0010] As a further optimization of the present invention, the flipping drive assembly includes a first rotation drive component, a rotating shaft, a swing arm, and a limiting shaft. The output end of the first rotation drive component is connected to the rotating shaft, and the swing arm is fixedly connected to the rotating shaft. A support plate is provided at the end of the swing arm away from the rotating shaft. A limiting shaft is rotatably mounted at the end of the rotating shaft away from the first rotation drive component. A sleeve shaft is rotatably mounted on the limiting shaft, and a pressure plate is fixedly mounted on the sleeve shaft. A torsion spring is sleeved at the rotatable connection between the sleeve shaft and the limiting shaft.

[0011] As a further optimization of the present invention, the pallet is rotatably mounted on the swing arm via a support block, and a support seat is also fixedly provided on the swing arm. A torsion spring is sleeved at the rotatable connection between the swing arm and the support block. When the pallet is in the initial position, the support block and the support seat are spaced apart. When the welding nut is conveyed onto the pallet, the pallet swings until the support block and the support seat abut against each other. The tilt angle of the welding nut received by the pallet is greater than the tilt angle of the welding nut in the conversion groove.

[0012] As a further optimization of the present invention, an anti-slip pad is embedded on the end face of the pressure plate facing the support plate.

[0013] As a further optimization of the present invention, the welding mechanism includes an upper welding electrode, a lower welding electrode, a lifting drive assembly, a translation drive assembly, and a platform. The translation drive assembly is disposed on the worktable, and its output end is connected to a translation seat. The lifting drive assembly is disposed on the translation seat, and its output end is connected to a lifting seat. The upper welding electrode is mounted on the lifting seat. The platform is used to place the plate. The lower welding electrode is disposed on the platform, and the plate rubs against the lower welding electrode.

[0014] As a further optimization of the present invention, a limiting rod is provided at the lower end of the upper welding electrode. When the upper welding electrode is in the welding position, the limiting rod is inserted into the threaded hole of the welding nut and used to limit and fix the welding nut.

[0015] The present invention has at least the following beneficial effects: The automatic welding device for installing and fixing electromechanical facilities provided by the present invention includes a feeding mechanism, a flipping mechanism, a clamping mechanism and a welding mechanism. The welding nut to be welded is conveyed by the feeding mechanism to the conveying groove of the conveying frame. Then, the flipping mechanism flips the welding nut conveyed upright in the conveying groove to an inverted state, so that the clamping mechanism can clamp and move it to the welding position. The welding mechanism then performs welding operations on the welding nut and the plate. Throughout the conveying process, the welding protrusions of the welding nut are distributed upwards, avoiding excessive friction between the welding protrusions and the conveying groove, effectively preventing excessive wear, deformation or end face damage of the welding protrusions, thereby ensuring the quality of the welding protrusions and further ensuring the welding quality between the subsequent welding nut and the plate. Moreover, the material turning mechanism includes a conversion frame, a pushing component, and a turning component. A conversion boss is provided on one side of the conversion slot on the conversion frame. The side wall of the conversion boss facing the conversion slot is inclined. When the welding nut is pushed into the conversion slot, the welding nut loses its bearing force on the left side, causing the welding nut to tilt on one side and overlap on the conversion boss, thus achieving the initial turning of the welding nut at a certain angle. Then, with the help of the turning component, the tilted welding nut is grabbed and turned into an inverted state to achieve the step-by-step turning of the welding nut. The flipping assembly includes a first rotation drive, a rotating shaft, a swing arm, and a limiting shaft. Driven by the first rotation drive, the rotating shaft drives the swing arm to rotate. Before the welding protrusion abuts against the pressure plate, the pressure plate is in a vertical state. After the welding protrusion abuts against the pressure plate, the pressure plate rotates counterclockwise under the continued drive of the first rotation drive until the pressure plate is in a horizontal state. The pressure plate serves as a platform for placing the welding nut in the inverted state. Furthermore, the double-sided limiting of the welding base by the support plate and the pressure plate ensures that the welding nut will not further tip over and fall off the support plate during the inverted process, thus ensuring the stability of the flipping.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] In the description of the embodiments of this application, it should be understood that the terms "upper", "lower", "left", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship that the product of this application is usually placed in, or the orientation or positional relationship that is commonly understood by those skilled in the art. They are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0020] like Figure 1 , Figure 2 As shown, the present invention provides an automatic welding device for installing and fixing electromechanical facilities, comprising: The feeding mechanism 3 and the conveying frame 31 are provided. The discharge end of the feeding mechanism 3 is connected to the inlet end of the conveying frame 31. The feeding mechanism 3 is used to convey the welding nut 202 to be welded into the conveying groove 311 of the conveying frame 31. The material turning mechanism 4 is used to turn the welding nut 202 that is being conveyed upright in the conveying trough 311 to an inverted state. A clamping mechanism is used to move the flipped welding nut 202 to the welding position; Welding mechanism 2 is set on workbench 1 and is used to weld welding nut 202 onto plate 201.

[0021] Continue to refer to Figure 2 The welding nut 202 includes a welding base 13, a welding protrusion 14, and a nut body 12. The welding base 13 is fixedly provided at one end of the nut body 12, and the welding protrusion 14 is provided at the end of the welding base 13 away from the nut body 12. A threaded hole 15 is opened at the axis of the nut body 12, and the threaded hole 15 passes through the welding base 13. When the welding nut 202 is in the welding position, the welding protrusion 14 rubs against the plate 201. When the welding nut 202 is in the upright position, the welding protrusion 14 of the welding nut 202 is arranged upward. When the welding nut 202 is in the inverted position, the welding protrusion 14 of the welding nut 202 is arranged downward.

[0022] It should be noted that in the welding of nuts on components such as machine bases and sheet metal parts of electromechanical equipment, such as... Figure 2 As shown, the welding nut 202 relies on the pre-set welding protrusion 14 at its end for centralized heating and reliable fusion. The integrity of the welding protrusion 14 directly affects the welding quality. Traditional automatic conveying devices often use open slides or ordinary vibratory feeding structures. During conveying, sorting, and pushing, the welding nuts 202 are prone to mutual collisions, squeezing, and continuous friction with the conveying track, leading to excessive wear, deformation, or end-face damage of the welding protrusion 14. Failure of the welding protrusion 14 will cause uneven current distribution and uneven heating during welding, easily resulting in problems such as incomplete welds, insufficient penetration, and nut positioning misalignment, seriously affecting the connection strength and assembly accuracy of the electromechanical installation. Existing conveying mechanisms lack targeted protective structures for the nut protrusions, making it difficult to meet the requirements of high-quality, continuous, automated welding.

[0023] Because the conveying trajectory of the welding nut 202 is long, during the conveying process, the above-mentioned technical solution uses a feeding mechanism 3 to convey the welding nut 202 to be welded upright. Figure 2 The welding nut 202 is positioned upright, with the welding protrusion 14 facing upwards. Near the unloading position, the welding nut 202 is flipped so that the flipping mechanism 4 flips the welding nut 202, which is being conveyed upright in the conveying trough 311, to an inverted position, with the welding protrusion 14 facing downwards. At this time, the inverted welding nut 202 is clamped and transferred to the corresponding welding position on the plate 201 by the clamping mechanism. The above method effectively avoids excessive friction between the welding protrusion 14 and the conveying trough 311, thereby ensuring the quality of the welding protrusion 14 and further ensuring the welding quality between the subsequent welding nut 202 and the plate 201.

[0024] It should be noted that the clamping mechanism (not shown in the figure) includes a robotic arm. The output end of the robotic arm is equipped with a gripper. The gripper laterally clamps the nut body 12 of the welding nut 202, and the welding nut 202 is spatially displaced by the rotation and displacement of the robotic arm. The specific displacement trajectory of the robotic arm can be preset according to the spatial arrangement of the device, which will not be elaborated here.

[0025] For further reference Figure 3 The welding mechanism 2 includes an upper welding electrode 21, a lower welding electrode (not shown in the figure), a lifting drive assembly 221, a translation drive assembly 231, and a platform 203. The translation drive assembly 231 is mounted on the worktable 1, and its output end is connected to a translation seat 23. The lifting drive assembly 221 is mounted on the translation seat 23, and its output end is connected to a lifting seat 22. The upper welding electrode 21 is mounted on the lifting seat 22. The platform 203 is used to place the plate 201, and the lower welding electrode is mounted on the platform 203, with the plate 201 in frictional contact with the lower welding electrode.

[0026] For example, the lifting drive assembly 221 includes a motor, a lead screw, and a slide rail. The motor drives the lead screw to rotate, and the lifting seat 22 is threadedly connected to the lead screw and slides in cooperation with the slide rail, so that the lifting seat 22 moves up and down. Similarly, the translation drive assembly 231 has the same structural configuration as the lifting drive assembly 221. It also drives the lead screw with a motor, and the translation seat 23 is threadedly connected to the lead screw and slides in cooperation with the slide rail, so that the translation seat 23 moves horizontally back and forth. This is not limited here.

[0027] For the welding nut 202 placed in the welding position, under the drive of the translation drive component 231, the upper welding electrode 21 is translated to be directly above the welding nut 202. Under the drive of the lifting drive component 221, the upper welding electrode 21 moves down to abut against the welding nut 202, so that the upper welding electrode 21, the welding nut 202, the plate 201 and the lower welding electrode form a circuit. The current will be concentrated on the tiny contact surface between the welding protrusion 14 and the plate 201, where the contact resistance is the largest. According to Q=I 2 Rt instantly generates extremely high heat, causing the welding protrusion 14 and plate 201 to melt rapidly in a localized manner, forming a weld nugget. After the power is cut off, the weld nugget cools and solidifies, thus forming a solid weld nugget. The upper welding electrode 21 is then lifted to complete the welding process.

[0028] The upper welding electrode 21 has a limiting rod at its lower end. When the upper welding electrode 21 is in the welding position, the limiting rod is inserted into the threaded hole 15 of the welding nut 202 and used to limit and fix the welding nut 202. This prevents the welding nut 202 from shifting during the welding process, ensuring that the threaded hole 15 of the welding nut 202 corresponds to the threaded hole on the plate 201, thus guaranteeing welding accuracy.

[0029] It should be noted that further reading is required. Figure 3 Multiple limiting blocks 204 are provided on the stage 203. The limiting blocks 204 are used to limit and fix the plate 201, so that the position of the threaded hole on the plate 201 corresponds to the position of the welding electrode.

[0030] For example, see [link to relevant documentation]. Figure 4 , Figure 6 and Figure 7 The material turning mechanism 4 includes a conversion frame 32, a pushing component 41, and a turning component 42. The discharge end of the conveying frame 31 is connected to the inlet end of the conversion frame 32. The conversion frame 32 is provided with a conversion groove 321. The feeding mechanism 3 is used to push the welding nut 202 in the conveying groove 311 into the conversion groove 321. A conversion boss 322 is provided on one side of the conversion groove 321. Figure 7 As shown, the side wall of the conversion boss 322 facing the conversion groove 321 is an inclined surface. (Continue reading...) Figure 6 Since the sidewall of the conveying trough 311 is a vertical surface, when the welding nut 202 is pushed into the conversion trough 321, the welding nut 202 is affected by the left side (with... Figure 7 (Taking the orientation shown as an example) Loss of bearing capacity causes the welding nut 202 to tilt to one side and overlap onto the conversion boss 322. Furthermore, due to the polygonal structure of the nut body 12 itself, the polygonal plane of the tilted nut body 12 abuts against the inclined surface of the conversion boss 322. Even if the polygonal edges of the nut body 12 abut against the inclined surface, it will rotate due to its own gravity until the polygonal plane abuts against the inclined surface, ensuring the stable tilted placement of the nut body 12 on the conversion boss 322. The conversion boss 322 facilitates the welding of the nut 202. The initial flipping is performed at a certain angle. The propulsion component 41 is mounted on the conversion frame 32, which is mounted on the workbench 1 via the base 33. The propulsion component 41 is located on the side of the conversion boss 322 away from the conversion groove 321. The propulsion component 41 is used to push the welding nut 202 in the conversion groove 321 forward. The flipping component 42 is located on the side of the conversion groove 321 away from the conveying groove 311. The flipping component 42 is used to flip the inclined welding nut 202 to an inverted state, and further flip the welding nut 202 with the help of the flipping component 42.

[0031] It should be noted that the direction in which the welding nut 202 is pushed forward refers to the conveying direction of the welding nut 202.

[0032] For example, see [link to relevant documentation]. Figure 7 and Figure 8 The propulsion assembly 41 includes a propulsion drive assembly 413, a second rotation drive member 412, and a propulsion plate 411. The output end of the propulsion drive assembly 413 is provided with a mounting base, and the second rotation drive member 412 is mounted on the mounting base. The output end of the second rotation drive member 412 is fixedly connected to the propulsion plate 411. The lower end of the propulsion plate 411 has an arc-shaped protrusion. When the propulsion plate 411 swings to the propulsion position under the drive of the second rotation drive member 412, the propulsion plate 411 is located behind the first welding nut 202 in the conversion groove 321, and the propulsion plate 411 rubs against the side wall of the welding base 13 of the welding nut 202. In the direction of conveying the welding nut 202 in the conversion groove 321, the last welding nut 202 in the conversion groove 321 is regarded as the first welding nut 202.

[0033] For example, the propulsion drive assembly 413 includes a motor, a lead screw, and a slide rail. The motor drives the lead screw to rotate, and the mounting seat is threaded onto the lead screw and slides in cooperation with the slide rail, causing the mounting seat to drive the second rotation drive member 412 to reciprocate, thereby realizing the reciprocating movement of the propulsion plate 411. For example, the second rotation drive member 412 is a drive motor.

[0034] In the above embodiment, for the welding nut 202 pushed into the conversion slot 321, the second rotation drive 412 drives the push plate 411 clockwise (towards) Figure 7 (Taking the orientation shown as an example) The push plate 411 is rotated so that it is inserted between the welding nut 202 in the conversion slot 321 and the welding nut 202 in the conveying slot 311. At this time, the push plate 411 rubs against the welding base 13 of the welding nut 202 in the conversion slot 321. Then, driven by the push drive assembly 413, the push plate 411 moves in the conveying direction of the conversion frame 32 to push the welding nut 202 in the conversion slot 321 forward. It should be noted that the push plate 411 pushes the welding base 13 of the welding nut 202 one diameter distance at a time. After that, the second rotation drive member 412 drives the push plate 411 to rotate counterclockwise again, and under the reverse drive of the push drive assembly 413, the push plate 411 is reset to the initial position.

[0035] For example, see [link to relevant documentation]. Figure 9 , Figure 10 , Figure 11 and Figure 12The flipping assembly 42 includes a support plate 428, a pressure plate 426, and a flipping drive assembly. The support plate 428 has an L-shaped structure and is used to receive the welding nut 202 pushed in by the push plate 411. The output end of the flipping drive assembly is connected to the support plate 428. The flipping drive assembly is used to drive the support plate 428 to swing until the welding nut 202 abuts against the pressure plate 426, and the pressure plate 426 swings from a vertical position to a horizontal position under the abutment of the welding nut 202. At this time, the welding nut 202 is in an inverted state.

[0036] The welded nut 202, pushed and squeezed out by the pusher plate 411, falls off from the conversion slot 321 and is caught by the support plate 428. Figure 9 As shown, then, driven by the flip drive assembly, the tray 428 is rotated counterclockwise (towards...). Figure 9 (Taking the orientation shown as an example) Rotate until the welding protrusion 14 on the welding base 13 abuts against the pressure plate 426, and thus, under the continued drive of the flipping drive assembly, the support plate 428 swings counterclockwise with the pressure plate 426 to a horizontal state, as shown. Figure 12 As shown, at this time, the welding nut 202 is in the material picking position. At this point, the welding nut 202 is flipped so that the welding protrusion 14 faces downward, so that the clamping mechanism can clamp and move the welding nut 202.

[0037] For example, see [link to relevant documentation]. Figure 9 , Figure 10 , Figure 11 and Figure 12 The flipping drive assembly includes a first rotation drive 421, a rotating shaft 422, a swing arm 427, and a limiting shaft 424. The output end of the first rotation drive 421 is connected to the rotating shaft 422. The swing arm 427 is fixedly connected to the rotating shaft 422. A support plate 428 is provided at the end of the swing arm 427 away from the rotating shaft 422. The limiting shaft 424 is rotatably mounted at the end of the rotating shaft 422 away from the first rotation drive 421. A sleeve shaft 423 is rotatably mounted on the limiting shaft 424. A pressure plate 426 is fixedly mounted on the sleeve shaft 423. A torsion spring is sleeved at the rotatable connection between the sleeve shaft 423 and the limiting shaft 424. The limiting shaft 424 is fixedly mounted on a bracket 425, and the bracket 425 is fixedly mounted on the worktable 1.

[0038] For example, the first rotation drive 421 is a drive motor. Under the drive of the first rotation drive 421, the rotating shaft 422 drives the swing arm 427 to rotate. Before the welding protrusion 14 abuts against the pressure plate 426, the pressure plate 426 is in a vertical state. After the welding protrusion 14 abuts against the pressure plate 426, under the continued drive of the first rotation drive 421, the pressure plate 426 rotates counterclockwise. At this time, the sleeve shaft 423 rotates around the limiting shaft 424 until the pressure plate 426 is in a horizontal state. Figure 12As shown, at this time, the pressure plate 426 serves as a platform for placing the welding nut 202 in the inverted state. Furthermore, with the help of the support plate 428 and the pressure plate 426, the welding base 13 is limited on both sides, ensuring that the welding nut 202 will not further tip over and fall off the support plate 428 during the inversion process, thus ensuring the stability of the flipping.

[0039] Furthermore, an anti-slip pad is embedded on the end face of the pressure plate 426 facing the support plate 428. The anti-slip pad is made of soft material, which makes the welding protrusion 14 fit against the anti-slip pad, increasing the shaking resistance of the welding nut 202 during the flipping process.

[0040] It should be noted that further reading is required. Figure 9 , Figure 11 and Figure 12 The pallet 428 is rotatably mounted on the swing arm 427 via the support block 420. A support seat 429 is also fixedly mounted on the swing arm 427. A torsion spring is sleeved at the rotatable connection between the swing arm 427 and the support block 420. When the pallet 428 is in its initial position, as... Figure 11 As shown, under the action of the torsion spring, the support block 420 and the support seat 429 are spaced apart. At this time, the inclination angle of the bearing surface of the tray 428 is the same as the inclination angle of the inclination surface of the conversion boss 322, which facilitates the smooth pushing of the welding nut 202 in the conversion groove 321 onto the tray 428. When the welding nut 202 is conveyed onto the tray 428, as... Figure 9 As shown, under the weight of the welding nut 202, the support plate 428 rotates until it swings to the point where the support block 420 and the support seat 429 abut. At this time, the tilt angle of the welding nut 202 supported by the support plate 428 is greater than the tilt angle of the welding nut 202 in the conversion groove 321. That is, compared with the tilt state on the conversion boss 322, the welding nut 202 is further rotated by a certain angle to ensure the stable overlap of the welding nut 202 on the support plate 428.

[0041] It should be noted that, in use, the automatic welding device for installing and fixing the electromechanical facilities involves the welding nuts 202 to be welded being transported in an orderly manner to the conveying groove 311 of the conveying frame 31. The discharge end of the conveying groove 311 is connected to the inlet end of the conversion groove 321 of the conversion frame 32. Under the pressure of the subsequent welding nuts 202, the welding nuts 202 are pushed into the conversion groove 321. Under the constraint of the conversion boss 322, the welding nuts 202 are tilted and overlapped on the conversion boss 322. The initial rotation of the welding nuts 202 at a certain angle is achieved through the conversion boss 322. For the welding nut 202 that falls on the conversion boss 322, the push plate 411 in the initial position is driven by the second rotation drive member 412 to swing down to the rear of the first welding nut 202 in the conversion groove 321. Under the drive of the push drive assembly 413, the push plate 411 pushes the welding nut 202 in the conversion groove 321 forward, so that the welding nut 202 located at the foremost point in the push direction is pushed down the conversion groove 321 and falls on the support plate 428. Under the downward pressure of the welding nut 202, the support block 420 rotates and abuts against the support seat 429. At this time, the tilt angle of the welding nut 202 supported by the support plate 428 is greater than the tilt angle of the welding nut 202 in the conversion groove 321. That is, compared with the tilt state on the conversion boss 322, the welding nut 202 is further rotated by a certain angle to ensure the stable overlap of the welding nut 202 on the support plate 428. Then, the first rotation drive 421 is activated, causing the swing arm 427 to drive the support plate 428 to rotate counterclockwise. Since the pressure plate 426 is initially in a vertical position, the swinging support plate 428 drives the welding nut 202 to swing counterclockwise until the welding protrusion 14 rubs against the pressure plate 426. With the continued swinging of the swing arm 427, the pressure plate 426 rotates counterclockwise synchronously with the support plate 428 until the pressure plate 426 is in a horizontal position. Figure 12 As shown, the welding nut 202 is flipped upside down, and then the inverted welding nut 202 can be clamped and transferred to the welding position on the plate 201 by means of the clamping mechanism. Finally, driven by the translation drive assembly 231, the upper welding electrode 21 is translated to be directly above the welding nut 202. Then, driven by the lifting drive assembly 221, the upper welding electrode 21 moves down to abut against the welding nut 202, forming a circuit between the upper welding electrode 21, the welding nut 202, the plate 201, and the lower welding electrode. The current concentrates on the tiny contact surface between the welding protrusion 14 and the plate 201, where the contact resistance is highest. According to Q=I... 2 Rt instantly generates extremely high heat, causing the welding protrusion 14 and plate 201 to melt rapidly in a localized manner, forming a weld nugget. After the power is cut off, the weld nugget cools and solidifies, thus forming a solid weld nugget. The upper welding electrode 21 is then lifted to complete the welding process.
