It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0057] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0058] like Figure 1As shown, this embodiment provides a welding device 1000 for processing a coil assembly, the coil assembly includes a coil 2000 and a contact plate 3000, a welding wire 4000 is arranged between the coil 2000 to be welded and the contact plate 3000, the welding device 1000 can melt the welding wire 4000, and the welding wire 4000 to be melted solidifies, and the coil 2000 and the contact plate 3000 can be welded and fixed, thereby obtaining a coil assembly.

[0059] Combine Figure 1 The structure of the welding device 1000 is described as follows. Figure 1 As shown, the welding device 1000 includes a flipping mechanism 100, a base plate 200, a wire feeding mechanism 300, a welding mechanism 400, and an obstacle detection mechanism 600. The flipping mechanism 100, the wire feeding mechanism 300, and the welding mechanism 400 are all disposed on the base plate 200, with the flipping mechanism 100 and the wire feeding mechanism 300 located on either side of the welding mechanism 400. The flipping mechanism 100 is used to place the coil 2000 and the contact plate 3000 to be welded together, and the wire feeding mechanism 300 is used to provide welding wire 4000 between the coil 2000 and the contact plate 3000. The welding mechanism 400 includes an upper electrode 401 and a lower electrode 402 spaced apart along the Y direction. The preassembled coil 2000, welding wire 4000, and contact plate 3000 are placed between the upper electrode 401 and the lower electrode 402. The upper electrode 401 and the lower electrode 402 are energized to weld the coil 2000 and the contact plate 3000 together to form a coil assembly. The obstacle detection mechanism 600 is disposed on the base plate 200 and is used to detect whether the operator is in the tooling action area. When the obstacle detection mechanism 600 detects the operator in the tooling action area, the obstacle detection mechanism 600 can send a signal to the welding device 1000 to control the welding device 1000 to stop working, thereby playing a safety protection role and preventing the operator from operating incorrectly in the tooling action area and causing safety accidents. Specifically, the obstacle detection mechanism 600 can be a photoelectric switch, which has a long test distance and high detection accuracy.

[0060] like Figure 1As shown, the flip mechanism 100 is rotatably mounted on the base plate 200. The flip mechanism 100 can switch between a first position in which the coil 2000 and the contact plate 3000 are welded to the welding mechanism 400, and a second position in which the coil 2000 and the contact plate 3000 are positioned upward. When the flip mechanism 100 is in the first position, the welding mechanism 400 can weld the coil 2000 and the contact plate 3000 together. When the flip mechanism 100 is in the second position, the coil 2000 and the contact plate 3000 are positioned upward, making it easier for the operator to remove the welded coil 2000 and contact plate 3000 and place a new coil 2000 and contact plate 3000 to be welded on the flip mechanism 100. This facilitates visual operation for the operator, facilitates the operator's replacement and placement of the coil 2000 and contact plate 3000, improves the operator's operating comfort, and improves the processing efficiency of the coil assembly.

[0061] like Figure 1 and Figure 2 As shown, the base plate 200 includes a support assembly 201, and the support assembly 201 includes a third mounting plate 2011 and two bearing seats 2012 arranged thereon and spaced apart along the X direction. Pivot links are provided on both sides of the flipping mechanism 100, and each pivot link is pivotally connected to the corresponding bearing seat 2012, thereby realizing a smoother rotation of the flipping mechanism 100 relative to the support assembly 201, avoiding the jamming of the flipping mechanism 100 during the rotation process, and improving the efficiency of the operator in replacing the coil 2000 and the contact plate 3000.

[0062] like Figure 1 As shown, the welding device 1000 further includes a second drive assembly 700, which can drive the flip mechanism 100 to rotate relative to the support assembly 201, so that the flip mechanism 100 switches between the first position and the second position. This facilitates the operator to remove the welded coil 2000 and contact plate 3000 and place the new coil 2000 and contact plate 3000 to be welded on the flip mechanism 100, facilitates the operator's visual operation, and facilitates the operator's replacement and placement of the coil 2000 and contact plate 3000, thereby improving the operator's operating comfort and the processing efficiency of the coil assembly.

[0063] Specifically, if Figures 1 to 3As shown, the second drive assembly 700 includes a second linear drive member 701 and a motion conversion member 702. The second linear drive member 701 is arranged on the third mounting plate 2011. The motion conversion member 702 is respectively connected to the output end of the second linear drive member 701 and the flipping mechanism 100. The motion conversion member 702 can convert the linear motion along the Y direction output by the second linear drive member 701 into the rotation of the flipping mechanism 100, which can effectively reduce the size of the second drive assembly 700 in the X direction and realize a smaller size of the flipping mechanism 100 in the X direction.

[0064] Specifically, if Figure 2 and Figure 3 As shown, the motion conversion member 702 includes a second push rod 7022 and a guide protrusion 7023. One end of the second push rod 7022 is connected to the output end of the second linear drive member 701. The end of the second push rod 7022 away from the second linear drive member 701 is provided with a waist-shaped groove 70221. A guide protrusion 7023 is provided below the flip mechanism 100 and slides in the waist-shaped groove 70221. When the output end of the second linear drive member 701 extends forward in the Y direction, the second push rod 7022 is pushed forward in the Y direction, and the guide protrusion 7023 slides along the waist-shaped groove 70221. The flip mechanism 100 rotates clockwise relative to the support assembly 201, so that the side of the flip mechanism 100 where the coil 2000 and the contact plate 3000 are provided faces upward, making it easier for the operator to remove and replace the coil 2000 and the contact plate 3000.

[0065] like Figure 2 and Figure 3 As shown, the motion conversion member 702 also includes a first guide block 7021, which is arranged on the third mounting plate 2011. The first guide block 7021 is provided with a first guide hole extending along the Y direction. The second push rod 7022 is passed through the first guide hole and can slide along the first guide hole, which can avoid the second push rod 7022 from being deflected, thereby realizing precise driving of the flipping mechanism 100 to rotate.

[0066] In other embodiments, Figure 4As shown, the flip mechanism 100 includes a flip plate 1 and a second pivot shaft 5. The second pivot shaft 5 passes through the flip plate 1 and extends from both sides of the flip plate 1. The second pivot shafts 5 extending from both sides are respectively pivotally connected to corresponding bearing seats 2012. The motion conversion member 702 includes a first rack 7025 and a first gear 7024. The output end of the second linear drive member 700 is connected to the first rack 7025, which is slidably mounted on the support assembly 201. The first gear 7024 is sleeved around the outer periphery of the second pivot shaft 5 and meshes with the first rack 7025. When the output end of the first linear drive assembly 701 performs linear motion in the Y direction, the first rack 7025 drives the first gear 7024 to rotate, thereby achieving rotation of the flip plate 1 relative to the support assembly 201, thereby achieving the upward positioning of the flip plate 1 on which the coil 2000 and contact plate 3000 are located. The first rack 7025 and the first gear 7024 rotate smoothly, with high transmission accuracy, high transmission efficiency, accurate transmission ratio, large transmission torque and low noise.

[0067] Furthermore, Figure 5 As shown, the flip mechanism 100 further includes a reset mechanism 4, which is used to drive the flip mechanism 100 to reset to the first position, so that the welding wire 4000 on the wire feeding mechanism 300 is aligned with the side of the flip mechanism 100 where the coil 2000 and the contact plate 3000 are provided, ensuring that the welding wire 4000 can be inserted between the coil 2000 and the contact plate 3000, making it convenient for the welding mechanism 400 to subsequently weld the coil 2000 and the contact plate 3000. Specifically, as Figure 5 As shown, the reset mechanism 4 is a first tension spring, one end of the first tension spring is connected to the lower part of the flip mechanism 100, and the other end of the first tension spring is connected to the support assembly 201. When the output end of the second linear drive member 701 is retracted along the Y direction, the first tension spring causes the flip mechanism 100 to be turned as shown in FIG. Figure 5 The counterclockwise rotation shown enables the flip mechanism 100 to be set vertically, facilitating subsequent welding processes.

[0068] like Figure 1 As shown, the welding device 1000 also includes a driving mechanism 500, which includes a fourth driving component 501. The fourth driving component 501 can drive the flipping mechanism 100 to approach or move away from the welding mechanism 400 along the Y direction, so that the flipping mechanism 100 can be switched between the welding station and the replacement station.

[0069] Specifically, if Figure 1 and Figure 2As shown, the base plate 200 further includes a support plate 202, a third mounting plate 2011 is located above the support plate 202, the body of the fourth drive assembly 501 is disposed on the support plate 202, and the output end of the fourth drive assembly 501 is connected to the third mounting plate 2011. The output end of the fourth drive assembly 501 extends or retracts relative to the body of the fourth drive assembly 501 in the Y direction, thereby enabling the flip mechanism 100 to move in the Y direction. Specifically, the fourth drive assembly 501 of this embodiment can be a linear motor, a linear cylinder, or other mechanism capable of outputting an output to achieve motion. The linear motor and the linear cylinder can achieve precise control of the distance the flip mechanism 100 moves in the Y direction relative to the support plate 202.

[0070] In addition, if Figure 1 and Figure 2 As shown, the drive mechanism 500 further includes a guide assembly 502 disposed between the third mounting plate 2011 and the support plate 202. The guide assembly 502 enables the third mounting plate 2011 to move relative to the support plate 202 in the Y direction, thereby preventing the flip mechanism 100 from deflecting during movement. Specifically, the guide assembly 502 of this embodiment includes a slider and a guide rail extending in the Y direction. The slider is disposed at the bottom of the third mounting plate 2011 and is capable of sliding along the guide rail. The slider and the guide rail cooperate to provide a good guiding function for the sliding of the flip mechanism 100.

[0071] Among them, such as Figure 1 As shown, the driving mechanism 500 further includes a fifth driving assembly 503, which can drive the wire feeding mechanism 300 to move closer to or away from the welding mechanism 400 along the Y direction. Specifically, the fifth driving assembly 503 of this embodiment can be a linear motor, a linear cylinder, or other mechanism capable of outputting linear motion. The linear motor or linear cylinder can achieve precise control of the movement of the wire feeding mechanism 300 relative to the support plate 202.

[0072] Furthermore, Figure 2 As shown, the flipping mechanism 100 also includes a first installation station 2 and a second installation station 3. The first installation station 2 is used to install the coil 2000, and the second installation station 3 is used to install the contact plate 3000. The welding device 1000 also includes a first driving component 800. The first driving component 800 can drive the first installation station 2 and the second installation station 3 to move relative to each other to adjust the gap between the coil 2000 and the contact plate 3000, so that the welding wire 4000 provided by the welding mechanism 400 can be inserted into the gap between the coil 2000 and the contact plate 3000, thereby improving the welding efficiency of the welding device 1000 and improving the yield of the processed coil assembly.

[0073] Specifically, if Figure 2 and Figure 3As shown, the first installation station 2 is slidingly connected to the flip plate 1, and the first drive assembly 800 includes a first linear drive member 801, a first push rod 803 and a follower 804. The first push rod 803 is connected to the output end of the first linear drive member 801, and the follower 804 is arranged on the first installation station 2. The first linear drive member 801 drives the first push rod 803 to move so that the follower 804 moves in the vertical direction, thereby driving the first installation station 2 and the second installation station 3 to move relative to each other in the vertical direction, so that a gap is formed between the coil 2000 and the contact plate 3000 in the vertical direction. Among them, a first inclined surface 8031 is provided at one end of the first push rod 803 away from the first linear drive member 801, and the first inclined surface 8031 abuts against the follower 804. The first inclined surface 8031 is inclined from top to bottom toward the extension direction of the first linear drive member 801. When the output end of the first linear drive member 801 is extended, the follower 804 slides along the first inclined surface 8031, and the first installation station 2 moves upward, so that a gap is formed between the coil 2000 and the contact plate 3000 along the Z direction, which facilitates the wire feeding mechanism 300 to insert the welding wire 4000 between the coil 2000 and the contact plate 3000. When the welding wire 4000 has been placed between the coil 2000 and the contact plate 3000, the output end of the first linear drive member 801 is retracted, and the first installation station 2 moves downward along the Z direction, so that the coil 2000 and the contact plate 3000 can jointly clamp the welding wire 4000, facilitating the normal progress of the subsequent welding process, avoiding the situation where the coil 2000 and the contact plate 3000 are not tightened due to the large gap between the coil 2000 and the contact plate 3000, and ensuring a stable welding effect of the coil 2000 and the contact plate 3000.

[0074] In other embodiments, the second installation station 3 may be slidingly connected to the flip plate 1, and the follower 804 may be arranged on the second installation station 3. The first linear drive member 801 drives the first push rod 803 to move so that the follower 804 moves in the vertical direction, thereby driving the second installation station 3 and the first installation station 2 to move relative to each other in the vertical direction, so that a gap is formed between the coil 2000 and the contact plate 3000 in the vertical direction.

[0075] In addition, if Figure 3 As shown, the first drive assembly 800 also includes a second guide block 802, which is arranged on the third mounting plate 2011. A second guide hole is opened on the second guide block 802, and the first push rod 803 is passed through the second guide hole. The second guide block 802 can prevent the first push rod 803 from being deflected, thereby realizing precise driving of the first installation station 2 in the vertical direction.

[0076] As a preferred solution, Figure 5As shown, the first installation station 2 further includes a second tension spring 24, one end of which is connected to the first installation station 2, and the other end of which is connected to the flip plate 1, thereby enabling the first installation station 2 to be suspended on the flip plate 1. As a preferred embodiment, the second installation station 3 further includes a third tension spring 34, one end of which is connected to the second installation station 3, and the other end of which is connected to the flip plate 1, thereby enabling the second installation station 3 to be suspended on the flip plate 1.

[0077] As a preferred solution, Figure 2 As shown, the first installation station 2 includes a first installation plate 21, a first positioning plate 22 and a first clamping cylinder 23. The first positioning plate 22 and the first clamping cylinder 23 are arranged on the first installation plate 21, and the coil 2000 is placed on the first positioning plate 22. The output end of the first clamping cylinder 23 can press the coil 2000 against the first positioning plate 22. The first positioning plate 22 and the first clamping cylinder 23 cooperate to ensure that the coil 2000 is firmly installed in the first installation station and ensure the precise positioning of the coil 2000, thereby obtaining a coil assembly with better quality.

[0078] As a preferred solution, Figure 2 As shown, the second installation station 3 includes a second installation plate 31, a second positioning plate 32, and a second pressing cylinder 33. The second positioning plate 32 and the second pressing cylinder 33 are arranged on the second installation plate 31, and the contact plate 3000 is placed on the second positioning plate 32. The output end of the second pressing cylinder 33 can press the contact plate 3000 against the second positioning plate 32. The second positioning plate 32 and the second pressing cylinder 33 cooperate to ensure that the contact plate 3000 is firmly installed in the second installation station 3 and accurately positioned, thereby obtaining a high-quality coil assembly.

[0079] As a preferred solution, Figure 2 and Figure 5 As shown, the flip mechanism 100 also includes an anti-slip structure 6, which is arranged on the flip plate 1 to limit the first installation station 2 and the second installation station 3 from escaping from the flip plate 1, ensuring the normal use of the welding device 1000 and avoiding personal injury.

[0080] Combine Figure 6 and Figure 7 The structure of the wire feeding mechanism 300 is described as follows. Figure 6 and Figure 7As shown, the wire feeding mechanism 300 includes a frame 307, a welding wire installation assembly 301, a clamping assembly 303, a feeding assembly 304 and a third driving assembly 302. The welding wire installation assembly 301 is used to place the welding wire 4000, the clamping assembly 303 is used to clamp the welding wire 4000, the clamping assembly 303 is slidably connected to the frame 307, the feeding assembly 304 is set on the frame 307 and is arranged in sequence with the clamping assembly 303 along the wire feeding direction. The third driving assembly 302 is used to drive the clamping assembly 303 to move and reset along the wire feeding direction, and is used to drive the feeding assembly 304 to transport the welding wire 4000.

[0081] The third drive assembly 302 drives the clamping assembly 303 to move toward the welding mechanism 400. The third drive assembly 302 also drives the feeding assembly 304 to deliver the welding wire 4000. The clamping assembly 303 can feed the free end of the welding wire 4000 between the coil 2000 and the contact plate 3000. Subsequently, the upper electrode 401 and the lower electrode 402 jointly clamp the coil 2000, the welding wire 4000, and the contact plate 3000. The upper electrode 401 and the lower electrode 402 are energized to weld the coil 2000 and the contact plate 3000 together.

[0082] Combine Figure 6 The structure of the feeding assembly 304 is described as follows. Figure 6 As shown, the feeding assembly 304 includes a first pivot shaft, a cam 3041, and a cam clamping plate 3042. The first pivot shaft is pivotally connected to the frame 307. The third driving assembly 302 can drive the first pivot shaft to rotate. The cam 3041 is fixed to the first pivot shaft. The cam clamping plate 3042 is disposed on the frame 307 and is spaced apart from the cam 3041 in the vertical direction. The welding wire 4000 passes through the gap between the cam 3041 and the cam clamping plate 3042. The third driving assembly 302 drives the cam 3041 to rotate so that the welding wire 4000 is fed along the wire feeding direction. The clamping stroke distance between the cam 3041 and the cam clamping plate 3042 is the wire feeding length of the welding wire 4000. The wire feeding length is adjusted by controlling the rotation angle of the cam 3041. Specifically, the third driving assembly 302 can be a cylinder slide, which has a simple structure and is easy to install.

[0083] As a preferred solution, Figure 5As shown, the third drive assembly 302 includes a third linear drive member 3021, a second rack 3022, and a second gear 3023. The third linear drive member 3021 is mounted on the frame 307. The second rack 3022 is fixed to the clamping assembly 303. The second rack 3022 is connected to the output end of the third linear drive member 3021. The second gear 3023 is mounted on the first pivot shaft and meshes with the second rack 3022. The third linear drive member 3021 can drive the second rack 3022 and the clamping assembly 303 to move in the Y direction. Simultaneously, the second rack 3022 drives the second gear 3023 and the cam 3041 to rotate, thereby feeding the welding wire 4000. Due to the specific structure of the third drive assembly 302 of this embodiment, only one third linear drive member 3021 is provided to simultaneously achieve the movement of the clamping assembly 303 and the feeding action of the feeding assembly 304, resulting in a simple structure, small footprint, and convenient operation.

[0084] Combine Figure 5 The specific structure of the clamping assembly 303 is described as follows. Figure 5 As shown, the clamping assembly 303 includes a mounting frame 3031, a torsion spring 3032 and a pressure plate 3033. The mounting frame 3031 is in the shape of a circular frame and is connected to the output end of the third drive assembly 302. The torsion spring 3032 is fixed in the mounting frame 3031. The pressure plate 3033 is arranged in the mounting frame 3031 and is pivotally connected to the mounting frame 3031. One end of the torsion spring 3032 abuts against the upper wall surface inside the mounting frame 3031, and the other end of the torsion spring 3032 abuts against the upper surface of the pressure plate 3033. The openings at both ends of the torsion spring 3032 face the welding mechanism 400. The clamping assembly 303 can prevent the welding wire 4000 from sliding relative to the clamping assembly 303 along the wire feeding direction, but can allow the welding wire 4000 to slip relative to the clamping assembly 303 in the opposite direction of the wire feeding direction.

[0085] Because upper electrode 401 and lower electrode 402 clamp coil 2000, welding wire 4000, and contact plate 3000, the clamping force between upper electrode 401 and lower electrode 402 is relatively large. When third drive assembly 302 drives clamping assembly 303 away from welding mechanism 400, clamping assembly 303 and feed assembly 304 slip relative to welding wire 4000, causing clamping assembly 303 and feed assembly 304 to reset. When welding mechanism 400 completes welding and the end of welding wire 4000 melts, fifth drive assembly 503 drives wire feed mechanism 300 to reset, and upper electrode 401 and lower electrode 402 reset.

[0086] Furthermore, in order to prevent the welding wire 4000 from being deflected during the feeding process and ensure that the welding wire 4000 is accurately inserted into the coil 2000 and the contact plate 3000, as shown in FIG. Figure 5As shown, the wire feeding mechanism 300 also includes a welding wire guide rail 306, which is arranged in front of the clamping assembly 303 along the wire feeding direction. A guide groove is provided on the welding wire 4000 guide rail, and the welding wire 4000 is passed through the guide groove, thereby ensuring that the welding wire 4000 has good straightness and can maintain a certain hardness, thereby ensuring that the welding wire 4000 is accurately inserted into the coil 2000 and the contact plate 3000.

[0087] like Figure 1 As shown, due to the long overall length of the welding wire 4000, the welding wire 4000 is wound on the welding wire installation assembly 301, which causes the welding wire 4000 coming out of the welding wire installation assembly 301 to have a certain curvature, making it inconvenient to subsequently insert it between the coil 2000 and the contact plate 3000. In order to solve the above problem, as Figure 1 and Figure 7 As shown, the wire feeding mechanism 300 also includes a shaping assembly 305 capable of straightening the welding wire 4000. The shaping assembly 305 is arranged at the rear end of the clamping assembly 303 along the wire feeding direction. The shaping assembly 305 includes a shaping mounting plate 3051 and a first roller group 3052 and a second roller group 3053 arranged thereon. The first roller group 3052 and the second roller group 3053 are spaced apart in the vertical direction. The welding wire 4000 is fed from the first roller group 3052 and the second roller group 3053. 3 passes through the gap in the vertical direction. The first roller group 3052 includes a plurality of first rollers 30521 arranged along the wire feeding direction. The second roller group 3053 includes a plurality of second rollers 30531 arranged along the wire feeding direction. The first roller group 3052 and the second roller group 3053 can achieve a good straightening effect on the welding wire 4000, facilitate further feeding of the welding wire 4000, and facilitate the subsequent smooth insertion of the welding wire 4000 between the coil 2000 and the contact plate 3000.

[0088] Combine Figures 1 to 7 The working process of the welding device 1000 is described as follows:

[0089] First, if Figure 1 and Figure 3 As shown, the output end of the second linear drive member 701 extends out, the second push rod 7022 extends out from the first guide block 7021, and the guide protrusion 7023 can slide along the waist-shaped groove 70221, thereby realizing the flipping mechanism 100 to set the first installation station 2 and the second installation station 3 on one side facing upward, and the operator places the coil 2000 and the contact plate 3000 on the first installation station 2 and the second installation station 3 respectively, and the output end of the first clamping cylinder 23 presses the coil 2000 on the first mounting plate 21, and the output end of the second clamping cylinder 33 presses the contact plate 3000 on the second mounting plate 31.

[0090] Then, if Figures 1 to 5As shown, the operator releases his hands, the obstacle detection mechanism 600 determines that the hands are not within the tooling action area, the output end of the second linear drive member 701 is retracted, and the reset mechanism 4 sets the flip mechanism 100 to set one side of the first installation station 2 and the second installation station 3 perpendicular to the third installation plate 2011, so that the coil 2000, the contact plate 3000 and the welding mechanism 400 are aligned, making it convenient for the welding wire 4000 to be inserted between the coil 2000 and the contact plate 3000.

[0091] Then, if Figure 1 As shown, the fourth driving assembly 501 drives the flip mechanism 100 to move to the position of the upper electrode 401 and the lower electrode 402, as shown in FIG. Figure 2 As shown, the first linear drive member 801 pushes the first push rod 803 to extend toward the welding mechanism 400, and the follower 804 slides along the first inclined surface 8031, thereby realizing the upward movement of the first installation station relative to the flip plate 21 in the vertical direction, thereby realizing the formation of a gap between the coil 2000 and the contact plate 3000 in the vertical direction. The formed gap facilitates the subsequent insertion of the welding wire 4000 into the coil 2000 and the contact plate 3000.

[0092] Then, if Figure 1 and Figure 6 As shown, the output end of the fifth driving assembly 503 drives the wire feeding mechanism 300 to move toward the welding mechanism 400, and the output end of the third linear driving member 3021 pushes the clamping assembly 303 to move toward the welding mechanism 400, while driving the second gear 3023 to rotate to rotate the cam 3041, and the welding wire 4000 passes through the welding wire guide rail 306 and is fed into the gap between the coil 2000 and the contact plate 3000. Figure 3 As shown, the output end of the first driving assembly 800 is retracted, the follower 804 is reset, the gap between the welding position of the coil 2000 and the contact plate 3000 is reset, the coil 2000 and the contact plate 3000 jointly clamp the welding wire 4000, and the addition of the welding wire 4000 is completed;

[0093] Then, the upper electrode 401 and the lower electrode 402 clamp the coil 2000 and the contact plate 3000, and the upper electrode 401 and the lower electrode 402 are electrically conductive to realize the welding of the coil 2000 and the contact plate 3000. Figure 5As shown, the third linear drive member 3021 drives the second rack 3022 and the clamping assembly 303 to reset. Simultaneously, the second rack 3022 drives the second gear 3023 and the cam 3041 to rotate in the opposite direction, thereby resetting the second gear 3023 and the cam 3041. Since the clamping force between the upper electrode 401 and the lower electrode 402 is relatively large, when the third linear drive member 3021 is reset, the clamping force of the pressure plate 3033 on the welding wire 4000 is less than the clamping force between the upper electrode 401 and the lower electrode 402. At this time, the welding wire 4000 and the pressure plate 3033 are in a slipping state. The reset stroke of the third linear drive member 3021 is equal to the feed length of the welding wire 4000.

[0094] Finally, if Figure 1 and Figure 5 As shown, when the welding wire 4000 is melted, the fifth drive component 503, the welding mechanism 400 and the fourth drive component 501 are reset respectively, and the output end of the unloading cylinder 25 is provided with a push rod, and the output end of the unloading cylinder 25 drives the push rod to push out the welded coil assembly. The whole process is completed and the cycle can be executed.
