[0002] In the manufacturing process of photovoltaic modules, defective cells with broken grids, poor soldering, or broken sections need to be reworked. This rework process requires applying flux and then soldering the grid lines. As the number of grid lines on the cells gradually increases, the operation requires frequent switching between fluxing and soldering tools, significantly reducing production efficiency and impacting the work cycle.

Utility Model Content

[0004] Therefore, it is necessary to provide a welding device to address the problem that frequent switching between coating and welding tools is required in the rework of defective battery cells, which significantly reduces production efficiency and affects the work cycle.

[0005] A welding apparatus, comprising:

[0006] A housing, the housing having a receiving cavity and an outlet communicating with the receiving cavity;

[0007] The working assembly includes a first working piece and a second working piece disposed in the receiving cavity, wherein the first working piece is used to apply flux and the second working piece is used for welding.

[0008] The telescopic mechanism includes a first telescopic mechanism and a second telescopic mechanism. Both the first telescopic mechanism and the second telescopic mechanism are connected to the housing and located within the receiving cavity. The first telescopic mechanism is driven to connect to the first working piece so that the first working piece extends out of the outlet or retracts. The second telescopic mechanism is driven to connect to the second working piece so that the second working piece extends out of the outlet or retracts.

[0009] In one embodiment, the first telescopic mechanism includes a first telescopic driver and a first guide assembly both connected to the housing and located in the receiving cavity, and the second telescopic mechanism includes a second telescopic driver and a second guide assembly both connected to the housing and located in the receiving cavity. The first telescopic driver is driven and connected to the first guide assembly, the first guide assembly is connected to the first working piece, the second telescopic driver is driven and connected to the second guide assembly, and the second guide assembly is connected to the second working piece.

[0010] In one embodiment, the first telescopic actuator includes a first electromagnetic lock, the second telescopic actuator includes a second electromagnetic lock, both the first guide component and the second guide component are magnetic, the first electromagnetic lock is located outside the first guide component, the second electromagnetic lock is located outside the second guide component, and the first electromagnetic lock and the second electromagnetic lock are configured to be energized to attract the first guide component and the second guide component respectively, or de-energized to release the first guide component and the second guide component.

[0011] In one embodiment, the first telescopic mechanism further includes a first elastic element, and the second telescopic mechanism further includes a second elastic element. The first elastic element is disposed between the first electromagnetic lock and the first guide assembly, and the second elastic element is disposed between the second electromagnetic lock and the second guide assembly. The first elastic element is used to compress when the first electromagnetic lock attracts the first guide assembly and to relax when the first electromagnetic lock releases the first guide assembly. The second elastic element is used to compress when the second electromagnetic lock attracts the second guide assembly and to relax when the second electromagnetic lock releases the second guide assembly.

[0012] In one embodiment, the welding apparatus further includes a rotating mechanism connected to the housing and located within the receiving cavity. The rotating mechanism simultaneously drives the first telescopic mechanism and the second telescopic mechanism connected to it to rotate about the axis of the housing, so that the first workpiece or the second workpiece is aligned with the outlet.

[0013] In one embodiment, the rotating mechanism includes a rotating driver and a transmission assembly. The rotating driver is connected to the housing and is driven by the transmission assembly. The transmission assembly is rotatably connected to the housing and is simultaneously driven by the first telescopic mechanism and the second telescopic mechanism.

[0014] In one embodiment, the welding apparatus further includes a limiting mechanism, which includes a first limiting structure and a second limiting structure. The first limiting structure is disposed on the inner peripheral wall of the housing, and the second limiting structure is disposed on the rotating mechanism. The second limiting structure is used to cooperate with the first limiting structure to limit the rotation of the rotating mechanism when the first workpiece or the second workpiece is aligned with the outlet.

[0015] In one embodiment, the first limiting structure includes a magnetic element, and the second limiting structure includes a magnetic induction element. The magnetic element is disposed on the inner peripheral wall of the housing, and the magnetic induction element is disposed on the rotating mechanism. The magnetic induction element is electrically connected to the rotating mechanism and is used to sense the magnetic element so as to stop the rotating mechanism from rotating when the first working piece or the second working piece is aligned with the outlet.

[0016] In one embodiment, the first limiting structure further includes a first limiting protrusion, and the second limiting structure further includes a second limiting protrusion. The first limiting protrusion protrudes radially from the inner peripheral wall of the housing, and the second limiting protrusion is disposed on the outer periphery of the rotating mechanism. The end of the second limiting protrusion along the radial direction of the housing is used to abut against the end of the first limiting protrusion along the radial direction of the housing, so as to stop the rotating mechanism from rotating when the first working piece or the second working piece is aligned with the outlet.

[0017] In one embodiment, the welding apparatus further includes a control mechanism electrically connected to the rotating mechanism, the first telescopic mechanism, and the second telescopic mechanism, such that either the first workpiece or the second workpiece extends out of the outlet while rotating to align with the outlet, or retracts relative to the outlet while rotating away from the outlet.

[0018] In operation, the aforementioned welding device first uses a first telescopic mechanism to extend the first workpiece out of the outlet, and a second telescopic mechanism to retract the second workpiece, allowing flux to be applied to the first workpiece. Then, the first telescopic mechanism retracts the first workpiece, and the second telescopic mechanism extends the second workpiece out of the outlet, allowing welding to proceed. This integrates the first and second workpieces into a single housing. The telescopic movements of the first and second mechanisms replace the manual alternation of applying and welding tools, eliminating the tedious steps of switching between them. This results in a smoother transition between flux application and welding, improving rework efficiency and accelerating production cycle time. Attached Figure Description

Detailed Implementation

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the manufacturing process of photovoltaic modules, defective cells with broken grids, poor soldering, or broken sections need to be reworked. During this rework process, flux needs to be applied before soldering the grid lines. As the number of grid lines on the cells gradually increases, frequent switching between fluxing and soldering tools is required, significantly reducing production efficiency and impacting the work cycle.

[0028] Please see Figures 1 to 3Based on the above problems, this application provides a welding device 100, including a housing 1, a working component, and a telescopic mechanism. The housing 1 has a receiving cavity 11 and an outlet 12 communicating with the receiving cavity 11; the working component includes a first working piece 21 and a second working piece 22 disposed in the receiving cavity 11, the first working piece 21 being used to apply flux, and the second working piece 22 being used for welding; the telescopic mechanism includes a first telescopic mechanism 31 and a second telescopic mechanism 32, both of which are connected to the housing 1 and located within the receiving cavity 11. The first telescopic mechanism 31 is driven to connect to the first working piece 21, causing the first working piece 21 to extend out of the outlet 12 or retract, and the second telescopic mechanism 32 is driven to connect to the second working piece 22, causing the second working piece 22 to extend out of the outlet 12 or retract. It is understood that, during use, the welding device 100 provided in this application firstly causes the first telescopic mechanism 31 to drive the first working piece 21 to extend out of the outlet 12, and then causes the second telescopic mechanism 32 to drive the second working piece 22 to retract, thereby applying flux to the first working piece 21. Then, the first telescopic mechanism 31 drives the first working part 21 to retract, and the second telescopic mechanism 32 drives the second working part 22 to extend out of the outlet 12, allowing the second working part 22 to be welded. Thus, the first working part 21 and the second working part 22 are integrated into a single housing 1. The telescopic movements of the first telescopic mechanism 31 and the second telescopic mechanism 32 replace the manual alternation of picking up and placing the fluxing tool and the welding tool, eliminating the tedious steps of switching between the two tools. This makes the fluxing and welding actions more seamless, improving rework efficiency and accelerating production cycle time.

[0029] In an optional embodiment, the first telescopic mechanism 31 and the second telescopic mechanism 32 may be a telescopic motor or a telescopic cylinder. The telescopic motor or telescopic cylinder may directly drive the first working member 21 or the second working member 22 to extend or retract relative to the outlet 12.

[0030] Please see Figure 4In other optional embodiments, in some embodiments, the first telescopic mechanism 31 includes a first telescopic actuator 311 and a first guide assembly 312, both connected to the housing 1 and located in the receiving cavity 11. The second telescopic mechanism 32 includes a second telescopic actuator 321 and a second guide assembly 322, both connected to the housing 1 and located in the receiving cavity 11. The first telescopic actuator 311 is driven to connect to the first guide assembly 312, and the first guide assembly 312 is connected to the first working member 21. The second telescopic actuator 321 is driven to connect to the second guide assembly 322, and the second guide assembly 322 is connected to the second working member 22. In other words, the first telescopic actuator 311 drives the first guide assembly 312 to cause the first working member 21 to extend out of the outlet 12 or retract. The second telescopic actuator 321 drives the second guide assembly 322 to cause the second working member 22 to extend out of the outlet 12 or retract. The first guide assembly 312 and the second guide assembly 322 are provided to make the telescopic movement of the first working piece 21 and the second working piece 22 relative to the outlet 12 more stable, and reduce the positional deviation and wear caused by the offset or shaking of the first working piece 21 and the second working piece 22 during the telescopic movement.

[0031] Please see Figure 4 In an optional embodiment, the first guide assembly 312 may include a first slide rail 3121 and a first slider 3122. The first slide rail 3121 is connected to the housing 1, the first slider 3122 is slidably connected to the first slide rail 3121, the first working piece 21 is connected to the first slider 3122, and the first telescopic actuator 311 is driven and connected to the first slider 3122, driving the first slider 3122 to slide along the first slide rail 3121 to extend or retract relative to the outlet 12. Similarly, the second guide assembly 322 may include a second slide rail 3221 and a second slider 3222. The second slide rail 3221 is connected to the housing 1, the second slider 3222 is slidably connected to the second slide rail 3221, the second working piece 22 is connected to the second slider 3222, and the second telescopic actuator 321 is driven and connected to the second slider 3222, driving the second slider 3222 to slide along the second slide rail 3221 to extend or retract relative to the outlet 12.

[0032] In other alternative embodiments, the first guide assembly 312 may include a first guide post and a first linear bearing. The first guide post is connected to the housing 1, the first linear bearing is slidably sleeved on the first guide post, the first working member 21 is connected to the first linear bearing, and the first telescopic actuator 311 is driven and connected to the first linear bearing, driving the first linear bearing to slide the first working member 21 along the first guide post to extend or retract relative to the outlet 12. Similarly, the second guide assembly 322 may include a second guide post and a second linear bearing. The second guide post is connected to the housing 1, the second linear bearing is slidably sleeved on the second guide post, the second working member 22 is connected to the second linear bearing, and the second telescopic actuator 321 is driven and connected to the second linear bearing, driving the second linear bearing to slide the second working member 22 along the second guide post to extend or retract relative to the outlet 12.

[0033] In an optional embodiment, the first telescopic actuator 311 may be a telescopic motor or a telescopic cylinder. The second telescopic actuator 321 may be a telescopic motor or a telescopic cylinder.

[0034] Please see Figure 4 In other optional embodiments, in some embodiments, the first telescopic actuator 311 includes a first electromagnetic lock 3111, the second telescopic actuator 321 includes a second electromagnetic lock 3211, and both the first guide component 312 and the second guide component 322 are magnetic. The first electromagnetic lock 3111 is located outside the first guide component 312, and the second electromagnetic lock 3211 is located outside the second guide component 322. The first electromagnetic lock 3111 and the second electromagnetic lock 3211 are configured to be energized to attract the first guide component 312 and the second guide component 322 respectively, or de-energized to release the first guide component 312 and the second guide component 322. The first electromagnetic lock 3111 and the second electromagnetic lock 3211 control the attraction and release by energizing and de-energizing, resulting in a small action switching delay and a fast response speed. This allows for rapid driving of the first guide component 312 and the second guide component 322 to complete the extension or retraction action, which helps to improve the switching efficiency of the first working piece 21 and the second working piece 22 during the rework process.

[0035] It should be noted that when the first electromagnetic lock 3111 and the second electromagnetic lock 3211 are energized, they generate an electromagnetic field, and their internal iron cores are magnetized, producing a strong magnetic force. The first guide component 312 and the second guide component 322 are magnetic, and a magnetic attraction is generated between them, thereby attracting the first guide component 312 and the second guide component 322 to the first electromagnetic lock 3111 and the second electromagnetic lock 3211. The first electromagnetic lock 3111 and the second electromagnetic lock 3211 are commercially available, and their specific structures will not be described in detail here.

[0036] Please see Figure 3 and Figure 4In an optional embodiment, the first electromagnetic lock 3111 may be disposed on the side of the first guide assembly 312 away from the outlet 12. When the first electromagnetic lock 3111 is energized, it attracts the first guide assembly 312 to move away from the outlet 12, thereby causing the first working piece 21 to retract relative to the outlet 12. When the first electromagnetic lock 3111 is de-energized, it releases the first guide assembly 312 to move towards the outlet 12, thereby causing the first working piece 21 to extend relative to the outlet 12.

[0037] Please see Figure 3 and Figure 4 In other alternative embodiments, the first electromagnetic lock 3111 may be disposed on the side of the first guide assembly 312 near the outlet 12. When the first electromagnetic lock 3111 is energized, it attracts the first guide assembly 312 to move toward the outlet 12, thereby causing the first working piece 21 to extend relative to the outlet 12. When the first electromagnetic lock 3111 is de-energized, it releases the first guide assembly 312 to move away from the outlet 12, thereby causing the first working piece 21 to retract relative to the outlet 12.

[0038] Please see Figure 3 and Figure 4 Similarly, in an optional embodiment, the second electromagnetic lock 3211 may be disposed on the side of the second guide assembly 322 away from the outlet 12. When the second electromagnetic lock 3211 is energized, it attracts the second guide assembly 322 to move away from the outlet 12, thereby causing the second working piece 22 to retract relative to the outlet 12. When the second electromagnetic lock 3211 is de-energized, it releases the second guide assembly 322 to move towards the outlet 12, thereby causing the second working piece 22 to extend relative to the outlet 12.

[0039] Please see Figure 3 and Figure 4 In other alternative embodiments, the second electromagnetic lock 3211 may be disposed on the side of the second guide assembly 322 near the outlet 12. When the second electromagnetic lock 3211 is energized, it attracts the second guide assembly 322 to move toward the outlet 12, thereby causing the second working piece 22 to extend relative to the outlet 12. When the second electromagnetic lock 3211 is de-energized, it releases the second guide assembly 322 to move away from the outlet 12, thereby causing the second working piece 22 to retract relative to the outlet 12.

[0040] Please see Figure 3 and Figure 4In optional embodiments, the first electromagnetic lock 3111 and the second electromagnetic lock 3211 may be arranged on the same side, both near or far from the outlet 12. Alternatively, the first electromagnetic lock 3111 and the second electromagnetic lock 3211 may be arranged on opposite sides, one near the outlet 12 and the other far from the outlet 12. This application does not limit the arrangement of the first electromagnetic lock 3111 and the second electromagnetic lock 3211; any position that allows the first working piece 21 and the second working piece 22 to extend or retract from the outlet 12 is within the protection scope of this application.

[0041] Please see Figure 3 and Figure 4 Preferably, the first electromagnetic lock 3111 is located on the side of the first guide assembly 312 away from the outlet 12, and the second electromagnetic lock 3211 is located on the side of the second guide assembly 322 away from the outlet 12. This avoids placing the first electromagnetic lock 3111 and the second electromagnetic lock 3211 close to the outlet 12, thereby reducing interference with the extension or retraction of the first working piece 21 and the second working piece 22.

[0042] Please see Figure 4 In some embodiments, the first telescopic mechanism 31 further includes a first elastic element 313, and the second telescopic mechanism 32 further includes a second elastic element 323. The first elastic element 313 is disposed between the first electromagnetic lock 3111 and the first guide component 312, and the second elastic element 323 is disposed between the second electromagnetic lock 3211 and the second guide component 322. The first elastic element 313 is used to compress when the first electromagnetic lock 3111 attracts the first guide component 312 and to relax when the first electromagnetic lock 3111 releases the first guide component 312. The second elastic element 323 is used to compress when the second electromagnetic lock 3211 attracts the second guide component 322 and to relax when the second electromagnetic lock 3211 releases the second guide component 322.

[0043] The first elastic element 313 and the second elastic element 323 enable automatic reset. When the first electromagnetic lock 3111 is de-energized and releases the first guide assembly 312, the compressed first elastic element 313 relaxes, pushing the first guide assembly 312 to reset the first working piece 21. Similarly, the second elastic element 323 can also push the second guide assembly 322 to reset the first working piece 21.

[0044] For example, when both the first electromagnetic lock 3111 and the second electromagnetic lock 3211 are located on the side of the first guide assembly 312 and the second guide assembly 322 away from the outlet 12: When the first electromagnetic lock 3111 is energized, it magnetically attracts the first guide assembly 312, causing the first working piece 21 to retract and the first elastic member 313 to be compressed; when the first electromagnetic lock 3111 is de-energized, it releases the first guide assembly 312, and the first elastic member 313 relaxes, pushing the first working piece 21 out of the outlet 12. When the second electromagnetic lock 3211 is energized, it magnetically attracts the second guide assembly 322, causing the second working piece 22 to retract and the second elastic member 323 to be compressed; when the second electromagnetic lock 3211 is de-energized, it releases the second guide assembly 322, and the second elastic member 323 relaxes, pushing the second working piece 22 out of the outlet 12.

[0045] Furthermore, the elastic deformation of the first elastic element 313 and the second elastic element 323 during compression can buffer the impact force generated at the moment of adsorption of the first electromagnetic lock 3111 and the second electromagnetic lock 3211, reducing rigid collisions between the first guide assembly 312 and the second guide assembly 322 and the first electromagnetic lock 3111 and the second electromagnetic lock 3211. This reduces component wear, extends the service life of the telescopic mechanism, and prevents positional displacement of the first guide assembly 312 and the second guide assembly 322 due to impact. Moreover, the first elastic element 313 and the second elastic element 323 can provide continuous and stable force during compression and expansion, making the telescopic movements of the first working member 21 and the second working member 22 smoother and reducing jamming or vibration.

[0046] The working process of the telescopic mechanism will be described below with a specific embodiment, taking the example where both the first electromagnetic lock 3111 and the second electromagnetic lock 3211 are located on the side of the first guide assembly 312 and the second guide assembly 322 away from the outlet 12. During rework using the welding device 100, the second electromagnetic lock 3211 is energized, causing it to attract the second slider 3222 of the second guide assembly 322. The second slider 3222 drives the second working piece 22 to retract relative to the outlet 12. The second slider 3222 and the second electromagnetic lock 3211 together compress the second elastic member 323. Simultaneously, the first electromagnetic lock 3111 is de-energized, causing it to release the first slider 3122 of the first guide assembly 312. The first elastic member 313 expands, pushing the first slider 3122 to extend the first working piece 21 out of the outlet 12. After the first working piece 21 extends out of the outlet 12, flux can be applied. Next, the second electromagnetic lock 3211 is de-energized, causing it to release the second slider 3222 of the second guide assembly 322. The second elastic element 323 expands, pushing the second slider 3222 to extend the second working piece 22 out of the outlet 12. After the second working piece 22 extends out of the outlet 12, welding can be performed. At the same time, the first electromagnetic lock 3111 is energized, causing it to attract the first slider 3122 of the first guide assembly 312. The first slider 3122 causes the first working piece 21 to retract relative to the outlet 12. The first slider 3122 and the first electromagnetic lock 3111 together compress the first elastic element 313.

[0047] Please see Figure 3 In some embodiments, the welding apparatus 100 further includes a rotating mechanism 4, which is connected to the housing 1 and located within the receiving cavity 11. The rotating mechanism 4 simultaneously drives the first telescopic mechanism 31 and the second telescopic mechanism 32, which are connected to each other, to rotate around the axis of the housing 1, so that the first working piece 21 or the second working piece 22 is aligned with the outlet 12. The rotating mechanism 4 allows the first working piece 21 and the second working piece 22 to switch positions within the housing 1, enabling them to share space on the same circumferential trajectory. The rotating mechanism 4 drives the first telescopic mechanism 31 and the second telescopic mechanism 32 to rotate 180°, achieving positional interchange of the first working piece 21 and the second working piece 22. This eliminates the need to reserve separate linear motion channels for the first working piece 21 and the second working piece 22, allowing for a more compact use of the space in the receiving cavity 11 of the housing 1, thus miniaturizing the welding apparatus 100.

[0048] Please see Figure 5In some embodiments, the rotating mechanism 4 includes a rotating driver 41 and a transmission assembly 42. The rotating driver 41 is connected to the housing 1 and is driven by the transmission assembly 42. The transmission assembly 42 is rotatably connected to the housing 1 and is simultaneously connected to the first telescopic mechanism 31 and the second telescopic mechanism 32. The transmission assembly 42 enables the rotational power of the rotating driver 41 to be transmitted more stably to the first telescopic mechanism 31 and the second telescopic mechanism 32, thereby making the switching of the positions of the first working piece 21 and the second working piece 22 more stable and reducing offset or shaking.

[0049] In an alternative embodiment, the rotary drive 41 may be a rotary motor or a rotary cylinder.

[0050] In an alternative embodiment, the transmission assembly 42 can be driven by a gear shaft or by a timing belt pulley and shaft.

[0051] Please see Figure 5 For example, the transmission assembly 42 includes a first gear 421, a second gear 422, and a rotating shaft 423, all located within the receiving cavity 11. The first gear 421 is sleeved on the output end of the rotary driver 41, and the second gear 422 is sleeved on the rotating shaft 423. The second gear 422 is meshed with the first gear 421. The rotating shaft 423 is rotatably connected to the housing 1 along the axis of the housing 1 and is connected to the first telescopic mechanism 31 and the second telescopic mechanism 32. The rotary driver 41 drives the second gear 422 to rotate via the first gear 421, which in turn causes the rotating shaft 423 to rotate, thereby causing the rotating shaft 423 to drive the first telescopic mechanism 31 and the second telescopic mechanism 32 to rotate.

[0052] Please see Figure 3 In some embodiments, the welding apparatus 100 further includes a limiting mechanism 5, which includes a first limiting structure 51 and a second limiting structure 52. The first limiting structure 51 is disposed on the inner peripheral wall of the housing 1, and the second limiting structure 52 is disposed on the rotating mechanism 4. The second limiting structure 52 is used to cooperate with the first limiting structure 51 to limit the rotation of the rotating mechanism 4 when the first working piece 21 or the second working piece 22 is aligned with the outlet 12. By setting the first limiting structure 51 and the second limiting structure 52, over-rotation of the rotating mechanism 4 can be avoided, and the first working piece 21 or the second working piece 22 can be prevented from failing to align with the outlet 12.

[0053] Please see Figure 3 and Figure 5In some embodiments, the first limiting structure 51 includes a magnetic element 511, and the second limiting structure 52 includes a magnetic induction element 521. The magnetic element 511 is disposed on the inner peripheral wall of the housing 1, and the magnetic induction element 521 is disposed on the rotating mechanism 4 and electrically connected to the rotating mechanism 4. The magnetic induction element 521 is used to sense the magnetic element 511 so that when the first working piece 21 or the second working piece 22 is aligned with the outlet 12, the rotating mechanism 4 stops rotating. The magnetic induction element 521 can sense the magnetic element 511 when it approaches itself to control the rotating mechanism 4 to stop rotating, thereby achieving limiting and preventing over-rotation.

[0054] In other alternative embodiments, the first limiting structure 51 includes a magnetic induction element 521, and the second limiting structure 52 includes a magnetic element 511. The magnetic induction element 521 is disposed on the inner peripheral wall of the housing 1, and the magnetic element 511 is disposed on the rotating mechanism 4. In other words, the embodiments of this application do not limit the placement position of the magnetic induction element 521 and the magnetic element 511.

[0055] Please see Figure 5 Furthermore, the rotating mechanism 4 is provided with two opposing magnetic induction elements 521 spaced apart along its own radial direction, and a magnetic element 511 is provided on the inner peripheral wall of the housing 1. Alternatively, the rotating mechanism 4 is provided with two opposing magnetic elements 511 spaced apart along its own radial direction, and a magnetic induction element 521 is provided on the inner peripheral wall of the housing 1.

[0056] Please see Figure 3 and Figure 5 Taking the example of a rotating mechanism 4 equipped with two magnetic induction elements 521 and a magnetic element 511 installed on the inner peripheral wall of the housing 1, when the rotating mechanism 4 drives the first working piece 21 to align with the outlet 12, one magnetic induction element 521 on the rotating mechanism 4 senses the magnetic element 511. The magnetic induction element 521 controls the rotating mechanism 4 to stop and limit its rotation, keeping the first working piece 21 at the outlet 12 position, where welding flux is applied. Next, the rotating mechanism 4 drives the second working piece 22 to rotate 180°, aligning the second working piece 22 with the outlet 12. The other magnetic induction element 521 on the rotating mechanism 4 rotates until it senses the magnetic element 511. The other magnetic induction element 521 controls the rotating mechanism 4 to stop and limit its rotation, keeping the second working piece 22 at the outlet 12 position, where welding is performed on the second working piece 22.

[0057] In optional embodiments, the magnetic sensing element 521 may be a Hall sensor, an anisotropic magnetoresistive sensor, a tunneling magnetoresistive sensor, etc. Preferably, the magnetic sensing element 521 is a Hall sensor. Hall sensors can achieve fast response and accurately realize position and velocity sensing.

[0058] In optional embodiments, the magnetic component 511 may be a cylindrical magnet, a disc magnet, a cube magnet, a tile magnet, etc.

[0059] In some embodiments, the first limiting structure 51 further includes a first limiting protrusion, and the second limiting structure 52 further includes a second limiting protrusion. The first limiting protrusion protrudes radially from the inner peripheral wall of the housing 1, and the second limiting protrusion is located on the outer periphery of the rotating mechanism 4. The radial end of the second limiting protrusion abuts against the radial end of the first limiting protrusion, so as to stop the rotating mechanism 4 from rotating when the first working piece 21 or the second working piece 22 is aligned with the outlet 12. In other words, when the rotating mechanism 4 drives the first working piece 21 or the second working piece 22 to align with the outlet 12, the end of the second limiting protrusion on the rotating mechanism 4 abuts against the end of the first limiting protrusion. The frictional restraint between the second limiting protrusion and the first limiting protrusion further prevents the rotating mechanism 4 from over-rotating.

[0060] In an optional embodiment, the first limiting protrusion is aligned with the magnetic element 511 on the inner wall of the housing 1 along the axial direction of the housing 1, and the second limiting protrusion is aligned with the magnetic induction element 521 on the rotating mechanism 4 along the axial direction of the rotating mechanism 4. Thus, the cooperation of the first limiting protrusion and the second limiting protrusion can be synchronized with the induction of the magnetic induction element 521 and the magnetic element 511, thereby synchronously limiting the rotation of the rotating mechanism 4.

[0061] In an optional embodiment, the second limiting protrusion and the magnetic induction element 521 are both provided on the rotating shaft 423 of the transmission assembly 42 of the rotating mechanism 4.

[0062] Please see Figure 1 and Figure 2 In some embodiments, the welding apparatus 100 further includes a control mechanism 6, which is electrically connected to the rotating mechanism 4, the first telescopic mechanism 31, and the second telescopic mechanism 32, so that either the first working piece 21 or the second working piece 22 extends out of the outlet 12 while rotating to align with it, or retracts relative to the outlet 12 while rotating away from it. In other words, the control mechanism 6 can drive the first telescopic mechanism 31, the second telescopic mechanism 32, and the rotating mechanism 4 to work simultaneously, thereby realizing the automated switching of the first working piece 21 and the second working piece 22 by the welding apparatus 100 and improving the switching efficiency.

[0063] Furthermore, the control mechanism 6 is electrically connected to the first electromagnetic lock 3111 of the first telescopic mechanism 31 and the second electromagnetic lock 3211 of the second telescopic mechanism 32. The control mechanism 6 is electrically connected to the rotary driver 41 of the rotary mechanism 4. The control mechanism 6 is electrically connected to the magnetic induction element 521, which senses the magnetic induction element and transmits the sense signal to the control mechanism 6, thereby controlling the rotary driver 41 to stop rotating.

[0064] It should be noted that the first working piece 21 is provided with a accommodating cavity for storing flux, and the first working piece 21 is provided with a solenoid valve, which is connected to the outlet 12 of the accommodating cavity and electrically connected to the control mechanism 6. When the first working piece 21 rotates to align with and extend from the outlet 12, the control mechanism 6 controls the solenoid valve to open, and the flux in the accommodating cavity flows out from the first working piece 21, thereby achieving the application of flux.

[0065] The second working piece 22 is equipped with a heating element, such as a semiconductor heating element, a resistance wire heating element, or a ceramic heating element, which is electrically connected to the control mechanism 6. When the second working piece 22 rotates to align with and extends out of the outlet 12, the control mechanism 6 controls the heating element to turn on, causing the temperature of the second working piece 22 to rise, thereby achieving welding. Please refer to [link to relevant documentation]. Figure 2 In an optional embodiment, the second working member 22 is provided with a wire for electric heating, the wire extending outside the housing 1. In order to avoid the wire, the end of the housing 1 opposite to the outlet 12 is provided with a relief groove 13, the relief groove 13 allowing the wire of the second working member 22 to pass through.

[0066] The working principles of the first telescopic mechanism 31, the second telescopic mechanism 32, the rotating mechanism 4, the limiting mechanism 5, and the control mechanism 6 of the welding device 100 provided in this application embodiment will be described in detail below with specific embodiments:

[0067] Please see Figures 1 to 5 When the welding device 100 is not in use, the control mechanism 6 energizes the first electromagnetic lock 3111 and the second electromagnetic lock 3211, causing the first electromagnetic lock 3111 and the second electromagnetic lock 3211 to attract the first guide component 312 and the second guide component 322 respectively, thereby causing the first working piece 21 and the second working piece 22 to retract relative to the outlet 12.

[0068] When the welding device 100 is in use, the first step is the flux application: the control mechanism 6 controls the rotation driver 41 of the rotation mechanism 4 to rotate, so that the first working piece 21 is aligned with the outlet 12. A magnetic induction element 521 on the rotation mechanism 4 senses the magnetic element 511 on the inner peripheral wall of the housing 1. The control mechanism 6 controls the rotation driver 41 to stop rotating, and the second limiting protrusion on the rotation mechanism 4 abuts against the first limiting protrusion on the inner peripheral wall of the housing 1. At the same time, the control mechanism 6 controls the first electromagnetic lock 3111 to de-energize. Under the action of the first elastic element 313, the first guide assembly 312 is pushed to drive the first working piece 21 out of the outlet 12. Then, the control mechanism 6 controls the first working piece 21 to release flux to complete the flux application.

[0069] Next comes the welding action: Control mechanism 6 controls the rotary driver 41 of rotary mechanism 4 to rotate 180°, so that the second working piece 22 is aligned with outlet 12. Another magnetic induction element 521 on rotary mechanism 4 senses the magnetic element 511 on the inner peripheral wall of housing 1. Control mechanism 6 controls rotary driver 41 to stop rotating, and the second limiting protrusion on rotary mechanism 4 abuts against the first limiting protrusion on the inner peripheral wall of housing 1. At the same time, control mechanism 6 controls the second electromagnetic lock 3211 to be de-energized. Under the action of the second elastic element 323, the second guide assembly 322 is pushed to drive the second working piece 22 out of outlet 12. Then, control mechanism 6 controls the heating element of the second working piece 22 to heat up to achieve welding.

[0070] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0071] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0072] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0073] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0074] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
