Description

Technical Field

[0001] This invention relates to the field of photovoltaic production technology, specifically to a junction box assembly equipment and method. Background Technology

[0002] Junction boxes, as commonly used protective and transitional components in the field of electrical connections, typically consist of a box body and a main structure with leads. During actual assembly, the leads on the main structure must be precisely inserted into the corresponding mounting holes or wiring positions on the box body to ensure smooth subsequent welding, continuity, and other processes, thereby achieving a stable electrical connection.

[0003] In traditional assembly methods, the main body and the housing are often independent components. During production, transportation, and material handling, the main body may experience positional shifts or angular deflections, resulting in inconsistent lead wire extension directions and a lack of consistent orientation. Because the lead wires are thin and relatively weak, it is difficult to quickly align them with the connectors on the housing when their orientations are inconsistent, easily leading to problems such as incomplete insertion, bending, deformation, or even failure to insert. This not only reduces assembly efficiency and fails to meet the high-speed requirements of automated production, but also affects subsequent welding quality due to insufficient lead wire insertion precision, increasing product defect rates and hindering efficient, stable, and precise automated assembly.

[0020] Furthermore, the rational layout and collaborative operation of each mechanism, along with the coordinated efforts of the main component supply mechanism and the lead wire alignment mechanism, ensure the orderly supply of main components and precise lead wire alignment. The seamless connection between the transmission mechanism and the installation and transfer mechanism guarantees the smooth transmission and assembly of the junction box.

The installation and transfer mechanism 400 includes a transfer gantry 410, multiple transfer components 430, and multiple lead wire identification cameras 440. The transfer gantry 410 is located on one side of the discharge end of the transmission mechanism 300. The multiple transfer components 430 and the lead wire identification cameras 440 are respectively located on opposite sides of the transfer gantry 410. Each transfer component 430 includes an opening and closing claw 432 and a material-pulling claw 434. The opening and closing claw 432 can move closer to / away from the transmission platform 330 to clamp. The assembly box includes a feeding claw 434 located inside the opening claw 432 and movable relative to each other along the second direction Y; a main component supply mechanism 600 located on one side of the mounting and transfer mechanism 400; and a lead wire alignment mechanism 500 located above the main component supply mechanism 600. The main component to be assembled is moved to the working area of ​​the lead wire alignment mechanism 500 via the main component supply mechanism 600. The lead wire alignment mechanism 500 includes an alignment base frame 51. 0 and multiple guiding components 520, any one of the guiding components 520 includes a connecting plate 521, a calibration beam 524 and two guiding beams 525. The connecting plate 521 is slidably connected to the guiding base frame 510 along the first direction X. The calibration beam 524 is disposed on the connecting plate 521 and extends along the first direction X. The two guiding beams 525 are movable relative to the calibration beam 524 along the first direction X and / or the second direction Y to respectively clamp and guide two leads on the main component to be assembled.

[0027] It should be noted that, for ease of description, in this embodiment, the length direction of the junction box assembly equipment is defined as the first direction X, the width direction of the junction box assembly equipment is defined as the second direction Y, and the height direction of the junction box assembly equipment is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other, and the first direction X and the second direction Y are located in the same plane.

[0028] In this embodiment, the box supply mechanism 200 serves as the starting point for box conveying in the equipment. Its core function is to achieve the orderly storage, sorting, and output of boxes to be assembled, providing a stable and continuous supply of box materials for subsequent assembly processes. This avoids the assembly process from stalling due to interruption or disorder in box supply, ensuring the smooth operation of the entire automated assembly line. It is the basic material supply guarantee structure for the equipment to achieve batch automated assembly.

[0029] Furthermore, the box supply mechanism 200 includes a feeding belt 210, a transfer robotic arm 220, and a feeding detection camera 230. The transfer robotic arm 220 is disposed at the discharge end of the feeding belt 210, and the feeding detection camera 230 is disposed above the feeding belt 210. The feeding belt 210 serves as a storage and conveying carrier for the boxes to be assembled, enabling the orderly batch transport of the boxes to the discharge end, providing a stable material source for subsequent transfer processes. The transfer robotic arm 220 is located at the discharge end of the feeding belt 210, and its core function is to accurately grab the boxes to be assembled from the feeding belt 210 and transfer them to the transfer platform 330 of the transfer mechanism 300, achieving a smooth transition of the boxes from the feeding belt 210 to the transfer mechanism 300 and ensuring the continuity of material transport. The feeding detection camera 230 is located above the feeding belt 210 and is used to perform real-time detection of the boxes transported on the feeding belt 210. It can accurately identify the placement posture of the boxes, whether there are any abnormalities such as damage or missing parts, and promptly screen out unqualified boxes to prevent abnormal boxes from entering subsequent assembly processes and affecting product quality. At the same time, it provides feedback on the position information of the boxes, providing data support for the precise grabbing of the transfer robotic arm 220, ensuring the accuracy and stability of the transfer process, and further ensuring the reliable operation of the entire box supply chain.

[0030] In this embodiment, the transmission mechanism 300 is located at the discharge end of the box supply mechanism 200 and serves as an intermediate conveying carrier for the boxes from supply to the assembly station. Its core function is to achieve precise and efficient transmission of the boxes to be assembled. The mounting box 310 serves as the mounting base for the transmission mechanism 300. Multiple transmission channels extending along the first direction X within the box enable parallel transmission of the boxes through multiple channels, significantly improving transmission efficiency and matching the high-speed cycle of automated production. Multiple transmission platforms 330, each corresponding to a transmission channel, stably support the boxes to be assembled and move precisely along the transmission channels, ensuring the boxes maintain a stable posture during transmission and preventing positional deviation. This provides reliable positional assurance for the subsequent precise clamping and assembly by the installation and transfer mechanism 400, while also enabling batch synchronous transmission of the boxes, further improving overall assembly efficiency.

[0031] The mounting box 310 includes a box body 311, a supporting top plate 312, and multiple partition beams 313. The supporting top plate 312 is supported above the box body 311. The multiple partition beams 313 are arranged at intervals along the second direction Y inside the box body 311, and any partition beam 313 extends along the first direction X to divide the internal space of the box body 311 into multiple transmission channels. The partition beams 313 are provided with guide rails 3131 extending in the same direction as them, and the transmission platform 330 is slidably connected to the guide rails 3131. The supporting top plate 312 supports the box body 311 and provides upper support and protection for the overall structure, ensuring the structural strength of the installation box 310. Multiple partition beams 313 are arranged at intervals along the second direction Y inside the box body 311 and extend along the first direction X, which can evenly divide the internal space of the box body 311 into multiple independent transmission channels, realize the parallel transmission of multiple boxes, and improve the overall assembly efficiency of the equipment. The partition beams 313 are provided with guide rails 3131 extending in the same direction as them. The transmission platform 330 is slidably connected to the guide rails 3131 to guide and limit the movement of the transmission platform 330, so that the transmission platform 330 moves stably along a predetermined path, avoiding deviation and shaking during transmission, and further improving the stability and positioning accuracy of the box transmission.

[0032] Specifically, the transmission mechanism 300 further includes a drive assembly 320, which includes a transmission driver 321, a drive shaft 322, a driven shaft, and a transmission belt 324. The transmission driver 321 is mounted on the mounting box 310. The drive shaft 322 and the driven shaft are respectively mounted on both sides of the box body 311 in the first direction X and both extend along the second direction Y. The drive shaft 322 is connected to the power output end of the transmission driver 321. Both the drive shaft 322 and the driven shaft are provided with reversing gears 323. The two ends of the transmission belt 324 are respectively sleeved on the reversing gears 323 of the drive shaft 322 and the reversing gears 323 of the driven shaft. Two transmission platforms 330 are connected to any one of the transmission belts 324, and the two transmission platforms 330 move relative to each other in the first direction X via the transmission belt 324.

[0033] The drive assembly 320 is the core power structure that provides movement power to the transmission platform 330 and ensures precise transmission of the housing. It includes a transmission driver 321, a drive shaft 322, a driven shaft, and a transmission belt 324. The transmission driver 321 is mounted on the mounting box 310 and serves as the power output source, providing power support for the entire drive assembly 320. The drive shaft 322 is connected to the power output end of the transmission driver 321 and can rotate under the drive of the transmission driver 321. The driven shaft provides auxiliary support and transmission reversal. A reversing gear 323 ensures smooth power transmission and guarantees the transmission belt 324's accurate transmission. 4. The transmission belt 324 runs stably along the first direction X. At the same time, the reversing gear 323 can effectively prevent the transmission belt 324 from slipping or deviating during the transmission process, ensuring transmission accuracy. Two transmission platforms 330 are connected to each transmission belt 324, and the two transmission platforms 330 move relative to each other along the first direction X via the transmission belt 324. This setting not only realizes the alternating operation of the two platforms in a single transmission channel, improving the transmission efficiency of the box, but also adapts to the box conveying needs of different workstations through relative movement, further ensuring that the transmission platform 330 drives the box to be assembled to move accurately to the designated position, providing reliable position guarantee for subsequent assembly processes.

[0034] Specifically, the transfer platform 330 includes a connecting frame 331 and a platform body 332. The platform body 332 is disposed on the connecting frame 331. A slider 3311 is provided on one side of the connecting frame 331, and a belt clamp 3312 is provided on the other side. The slider 3311 is slidably connected to the transfer gantry 410, and the belt clamp 3312 is clamped on the transfer belt 324 to move via the transfer belt 324. The box to be assembled is supported on the platform body 332. The platform body 332 is used to directly support and position the box to be assembled, ensuring that the box is stable in posture and accurate in position during the transfer process; the slider 3311 is slidably connected to the transfer gantry 410, and is used to provide guidance and support for the transfer platform 330, ensuring that the transfer platform 330 moves smoothly along the predetermined path, avoiding shaking or deviation, and improving the transfer accuracy; the belt clamp 3312 is clamped on the transfer belt 324, and can reliably move synchronously with the transfer belt 324, thereby transmitting power to the entire transfer platform 330, realizing the stable movement of the transfer platform 330 along the first direction X, thereby driving the box to be assembled to be transported to the assembly station in an orderly manner.

[0035] In this embodiment, the installation and transfer mechanism 400 is located on the discharge end side of the transmission mechanism 300. It is the core execution mechanism for achieving precise docking and assembly of the box and the main component lead wire. Its core function is to clamp and transfer the box to be assembled, as well as to accurately align the lead wire with the box insertion point. The transfer gantry 410 serves as the installation support foundation for the entire installation and transfer mechanism 400, providing a stable mounting carrier for the transfer assembly 430 and the lead wire recognition camera 440, while ensuring the installation position accuracy of each component and ensuring the stability of the mechanism's operation. Multiple transfer assemblies 430 and multiple lead wire recognition cameras 440 are respectively located on opposite sides of the transfer gantry 410, forming a coordinated operation. The core function of the lead wire recognition camera 440 is to accurately identify and verify the posture of the main component lead wire after it has been guided, and to provide real-time feedback on the position and posture information of the lead wire, providing data support for the precise docking of the transfer assembly 430 and avoiding docking failure due to lead wire posture deviation. The opening and closing claw 432 in the carrier component 430 can move closer to or further away from the transfer platform 330. Its core function is to accurately clamp the box to be assembled that is transported by the transfer platform 330 to the assembly station, ensuring that the box does not loosen or shift during the transfer and assembly process, and ensuring the positional stability of the box. The material-pulling claw 434 is set inside the opening and closing claw 432 and can move relative to each other in the second direction Y. Its core function is to assist in sorting the lead wire during the docking of the lead wire with the box, guiding the lead wire to accurately align with the mounting hole or wiring position of the box, while avoiding bending and deformation of the lead wire during the docking process, further improving the docking accuracy and ensuring the smooth progress of subsequent welding and conduction processes.

[0036] Furthermore, the installation and transfer mechanism 400 also includes multiple carriages 420. The transfer gantry 410 is provided with multiple adjusting rails 411 extending along the first direction X. The multiple carriages 420 are slidably connected to the multiple adjusting rails 411 respectively. Each carriage 420 is connected to a transfer component 430 and a lead wire recognition camera 440. The adjusting rails 411 are used to provide sliding guidance and positioning for the carriages 420 along the first direction X, so that the position of the carriages 420 can be adjusted according to the assembly specifications and workstation requirements. The carriages 420 are used to simultaneously install and fix the corresponding transfer component 430 and lead wire recognition camera 440, ensuring that the relative position between the transfer component 430 and the lead wire recognition camera 440 is stable and the positioning accuracy is consistent, thereby realizing the coordinated cooperation between the transfer action and visual recognition detection. At the same time, by independently adjusting multiple carriages 420, it can adapt to the assembly requirements of junction boxes of different specifications and different spacings, improving the versatility and adaptability of the equipment.

[0037] Specifically, the carriage 420 includes a sliding part 421, an assembly part 422, and a first lifting module 423. The sliding part 421 is slidably connected to the adjusting rail 411. One end of the assembly part 422 is connected to the sliding part 421, and the other end extends in the vertical direction Z. The first lifting module 423 is disposed on the side of the assembly part 422 facing the transmission mechanism 300 and extends in the same direction as the assembly part 422. The transfer component 430 is slidably connected to the first lifting module 423. The lead wire recognition camera 440 is connected to the side of the assembly part 422 away from the transmission mechanism 300. The sliding part 421 is slidably connected to the adjusting rail 411, used to realize the position adjustment and sliding guidance of the carriage 420 as a whole along the first direction X, to meet the adaptation requirements of different assembly stations and product specifications; the assembly part 422 is connected to the sliding part 421 at one end and extends along the vertical direction Z at the other end, used to provide a stable mounting carrier for the first lifting module 423, the transfer component 430 and the lead wire identification camera 440, to ensure that the relative positions of each component are fixed and the assembly accuracy is reliable; the first lifting module 423 is disposed on the side of the assembly part 422 facing the transmission mechanism 300 and extends in the same direction as the assembly part 422, used to drive the carriage 420 to move ... The transfer component 430 moves vertically Z-axis, allowing for height adjustment between different processes such as material handling, alignment, and insertion, ensuring precise execution of assembly actions. The transfer component 430 is slidably connected to the first lifting module 423 and can complete lifting actions under the drive of the first lifting module 423. The lead wire recognition camera 440 is connected to the side of the assembly part 422 away from the transmission mechanism 300, forming a stable spatial layout with the transfer component 430. This ensures clear recognition of the lead wire's posture while avoiding interference with assembly actions, thereby achieving collaborative work between visual recognition and transfer assembly, improving overall assembly accuracy and stability.

[0038] Furthermore, the transfer assembly 430 includes a first fine-tuning module 431, an opening / closing driver 433, and a material feeding driver 435. The first fine-tuning module 431 is disposed on the carriage 420 and extends along the second direction Y. The opening / closing driver 433 is slidably connected to the first fine-tuning module 431. The opening / closing claw 432 is connected to the power output end of the opening / closing driver 433 to open and close along the first direction X.

It is used to realize the fine position adjustment of the opening and closing driver 433 and the opening and closing claw 432 as a whole along the second direction Y, thereby improving the alignment accuracy. The opening and closing driver 433 is slidably connected to the first fine-tuning module 431, providing opening and closing power to the opening and closing claw 432, enabling the opening and closing claw 432 to open and close along the first direction X, thereby achieving stable clamping and reliable positioning of the box to be assembled.

[0039] In this embodiment, the main component supply mechanism 600 is located on one side of the installation and transfer mechanism 400. It is the core material supply structure for the main body structure with leads. Its core function is to achieve the orderly storage, transportation, and positioning of the main components to be assembled, accurately transporting them to the working area of ​​the lead wire alignment mechanism 500, providing stable material support for the lead wire alignment process. Simultaneously, in coordination with the working rhythm of the lead wire alignment mechanism 500 and the installation and transfer mechanism 400, it achieves seamless connection between the main component supply, alignment, and assembly processes, ensuring the continuity of the entire assembly process and avoiding the impact of disordered main component supply on assembly efficiency and accuracy. This invention does not impose specific limitations on the specific type and number of the main component supply mechanism 600.

[0040] In this embodiment, the lead wire alignment mechanism 500 is located above the main component supply mechanism 600. It is the core structure for solving the problem of messy lead wire posture in traditional assembly. Its core function is to accurately clamp and align the two leads on the main component, ensuring that the lead wires extend in a uniform direction and have a stable posture, thus laying the foundation for accurate insertion into the box. The guide frame 510 serves as the main support for the lead wire guiding mechanism 500, providing a stable installation platform for each guiding component 520 and ensuring the operational accuracy of the guiding components 520. Multiple guiding components 520 can simultaneously guide the leads of multiple main components, improving guiding efficiency and adapting to the needs of batch automated production. The connecting plate 521 in a single guiding component 520 can be slidably connected to the guide frame 510 along the first direction X. Its function is to drive the entire guiding component 520 to move along the first direction X, achieving precise alignment between the guiding component 520 and the main component conveyed by the main component supply mechanism 600, ensuring that the lead wire can accurately enter the guiding area. The calibration beam 524 is set on the connecting plate 521. Extending upwards along the first direction X, its function is to provide a positioning reference for the two guide beams 525, ensuring that the movement direction and clamping position of the two guide beams 525 are precisely controllable, and ensuring the consistency of the lead wire alignment; the two guide beams 525 can move relative to the calibration beam 524 along the first direction X and / or the second direction Y. Their core function is to clamp the two lead wires on the main component to be assembled, respectively. By precisely adjusting the movement position, the messy posture of the lead wires is corrected, so that the two lead wires maintain a uniform extension direction and spacing, which completely solves the problem of difficult insertion caused by messy lead wire direction and insufficient rigidity in traditional assembly, and provides a reliable guarantee for the precise docking and insertion process of the subsequent installation and transfer mechanism 400.

[0041] Furthermore, the guide frame 510 includes a fixed beam 511, a second lifting module 512, and a lifting connecting frame 513. The fixed beam 511 is disposed above the main component supply mechanism 600. The second lifting module 512 is disposed on the fixed beam 511 and extends in the vertical direction Z. The lifting connecting frame 513 is slidably connected to the second lifting module 512. A plurality of guide components 520 are respectively connected to the lifting connecting frame 513. The fixed beam 511 is mounted above the main component supply mechanism 600, providing a stable installation foundation and support positioning for the entire lead wire straightening mechanism 500, ensuring the overall structure is firm and reliable. The second lifting module 512 is set on the fixed beam 511 and extends along the vertical direction Z, providing vertical lifting drive and guidance for the lifting connecting frame 513 in the vertical direction Z, realizing precise adjustment of the height position of the straightening component 520 to adapt to the needs of main components and lead wire straightening stations of different height specifications. The lifting connecting frame 513 is slidably connected to the second lifting module 512, used to uniformly install and support multiple straightening components 520, so that multiple straightening components 520 can be lifted and lowered synchronously under the drive of the second lifting module 512, ensuring that the actions of each straightening component 520 are consistent and the positions are synchronized, thereby realizing the synchronous straightening operation of multiple main component leads, improving lead wire straightening efficiency and the automated assembly cycle of the overall equipment.

[0042] Specifically, the end of the lifting connecting frame 513 is provided with a second fine-tuning module 514, which extends along the second direction Y. The guiding component 520 is slidably connected to the second fine-tuning module 514. The second fine-tuning module 514 is used to finely adjust the position of the guiding component 520 in the second direction Y, so that the guiding component 520 can be accurately aligned with the main component and the lead wire, effectively compensating for positional deviations generated during assembly and transmission, further improving the accuracy and consistency of lead wire guidance, and ensuring stable and reliable guiding action.

[0043] Furthermore, the guiding assembly 520 also includes a telescopic actuator 522, a telescopic plate 523, and a guiding actuator 526. The telescopic actuator 522 is connected to the connecting plate 521, the telescopic plate 523 is connected to the power output end of the telescopic actuator 522 to move along the first direction X, the calibration beam 524 is disposed on the telescopic plate 523, the guiding actuator 526 is connected to the bottom surface of the telescopic plate 523, and the two guiding beams 525 are respectively connected to the two power output ends of the guiding actuator 526 to open and close relative to each other along the second direction Y. The telescopic actuator 522 can drive the telescopic plate 523 to move along the first direction X, thereby causing the calibration beam 524 and the guide beam 525 to move closer to or further away from the lead wire to be guided, realizing precise feeding and avoidance at the guiding station; the calibration beam 524 is set on the telescopic plate 523, providing a unified reference positioning for the two guide beams 525, ensuring the consistency and stability of lead wire guidance; the guiding actuator 526 is connected to the bottom surface of the telescopic plate 523, and the two guide beams 525 are respectively connected to the two power output ends of the guiding actuator 526, and can move relative to each other along the second direction Y under the drive of the guiding actuator 526, thereby clamping, returning and correcting the attitude of the lead wire, so that the messy lead wire is regulated into a uniform attitude, providing a reliable guarantee for subsequent precise insertion.

[0044] In this embodiment, the guide beam 525 includes a beam body 5251 and a straightening protrusion 5252. The beam body 5251 extends along the first direction X, with one end connected to the guide driver 526 and the other end connected to the straightening protrusion 5252. The straightening protrusion 5252 extends from the beam body 5251 toward the calibration beam 524 along the second direction Y. The beam body 5251 provides structural support and power transmission for the entire guide beam 525, ensuring stable movement of the guide beam 525. The straightening protrusion 5252, formed by the beam body 5251, directly contacts the lead wire during the straightening process. It clamps, straightens, and returns the lead wire to its correct position using the limiting space formed between the lead wire and the calibration beam 524, thus constraining the originally messy and skewed lead wire to a uniform and orderly posture. This prevents the lead wire from bending or shifting during the straightening and insertion process, further improving the lead wire straightening accuracy and assembly reliability.

[0045] In addition, the junction box assembly equipment in this embodiment also includes a base 100, which is equipped with an electrical control mechanism 700. The box supply mechanism 200, the transmission mechanism 300, the installation and transfer mechanism 400, the lead wire straightening mechanism 500, and the main component supply mechanism 600 are all disposed on the base 100 and are respectively connected to the electrical control mechanism 700. The base 100 serves as the installation foundation and support platform for the entire equipment, providing a stable and flat installation surface for the junction box supply mechanism 200, transmission mechanism 300, installation and transfer mechanism 400, lead wire alignment mechanism 500, and main component supply mechanism 600, ensuring accurate relative positions of each mechanism and stable and reliable operation. The electrical control mechanism 700 inside the base 100 is used to centrally control and coordinate the actions of each mechanism, realizing automated linkage and timing coordination of processes such as material supply, transmission, visual recognition, lead wire alignment, transfer and assembly, thereby improving the continuity, accuracy and automation of equipment operation, and ensuring that the entire assembly process of the junction box and lead wires is carried out efficiently, stably and orderly.

[0046] Example 2: This example provides a junction box assembly method, which uses the junction box assembly equipment described in Example 1 to assemble the junction box body and leads, and includes: Step S1: The box to be assembled is supplied to the conveying mechanism 300 through the box supply mechanism 200, and the main component to be assembled is supplied through the main component supply mechanism 600. This step ensures that the box and the main component arrive at the corresponding processing station synchronously, avoiding the interruption of the assembly process due to the delay in the supply of a single material, and ensuring the continuity of the entire assembly process. At the same time, the orderly supply of materials can prevent the box and the main component from being misaligned or damaged during the supply process, and provides qualified material guarantee for subsequent processes such as lead wire alignment and precise insertion. This is a prerequisite for realizing batch automated assembly.

[0047] Step S2: The lead wire identification camera 440 identifies the position of the lead wire of the main component within its identification range. When the identified lead wire position is in an unadjustable state, the main component supply mechanism 600 performs NG unloading and recycling. When the identified lead wire position is in an adjustable state, the lead wire guiding mechanism 500 adjusts the lead wire on the main component to a vertical state. First, the lead wire recognition camera 440 identifies the position of the lead wires on the main component within its recognition range, accurately acquiring the current posture and position information of the lead wires. This provides data support for subsequent alignment and guidance, preventing assembly failures caused by abnormal lead wire postures from the outset. Second, the recognition results determine whether the lead wire position is adjustable, enabling early screening of defective main components. When the lead wire position is not adjustable, the main component supply mechanism 600 performs unloading and recycling, preventing defective main components from entering subsequent processes, reducing ineffective assembly, and lowering product defect rates and material waste. When the lead wire position is adjustable, the lead wire alignment mechanism 500 adjusts the lead wires on the main component to a vertical position, completely solving the pain points of messy lead wire postures and inconsistent extension directions in traditional assembly. This provides a unified posture benchmark for the subsequent precise insertion of the lead wires into the housing, ensuring a smooth insertion process.

[0048] Furthermore, in step S2 of this embodiment, adjusting the lead wire on the main component to a vertical state via the lead wire straightening mechanism 500 specifically includes: Step S21: Drive the calibration beam 524 and the two guide beams 525 in the guide assembly 520 so that the lead wire to be guided is located between the two guide beams 525 and the calibration beam 524 respectively. Thus, by driving the calibration beam 524 and the two guide beams 525 in the guide assembly 520, the lead wire to be guided enters the preset guidance area between the two guide beams 525 and the calibration beam 524 respectively, realizing the initial limit and attitude centering of the lead wire, and providing a reliable spatial positioning basis for subsequent multi-directional precise guidance.

[0049] Step S22: Drive the two guide beams 525 toward the calibration beam 524 to guide the lead wire in the second direction Y. By driving the two guide beams 525 toward the calibration beam 524, the lead wire is clamped, straightened and constrained in the second direction Y, eliminating the lead wire's skewing, shaking and positional deviation in the second direction Y, so that the lead wire maintains a uniform and regular posture in the second direction Y.

[0050] Step S23: Drive the two guide beams 525 to move along the first direction X, so as to guide the lead wire in the first direction X through the straightening protrusions 5252 at the ends of the guide beams 525. By driving the two guide beams 525 to move along the first direction X, the straightening protrusions 5252 at the ends of the guide beams 525 are used to correct and position the lead wire in the first direction X, so that the lead wire also reaches the preset vertical posture in the first direction X. Thus, under the dual guiding action of the first direction X and the second direction Y, the lead wire is completely adjusted to a stable and uniform vertical state, providing a solid guarantee for the accurate insertion of the lead wire and the box body.

[0051] Step S3: The box to be assembled is moved by the opening and closing claws 432 in the transfer component 430 until the aligned lead wire is inserted into the box. At this time, the material-pulling claws 434 in the transfer component 430 are located between the two lead wires. This achieves precise alignment and preliminary insertion between the box and the aligned lead wire, laying the positional foundation for final assembly. This step moves the box to be assembled by the opening and closing claws 432 in the transfer component 430. The stable clamping capability of the opening and closing claws 432 ensures that the box is stable and accurately positioned during movement, avoiding box offset that would cause the lead wire to misalign with the insertion position. By precisely moving the box, the aligned vertical lead wire is inserted into the box, completing the preliminary fit between the lead wire and the box. At the same time, the material-pulling claws 434 are located between the two lead wires, laying the positional foundation for subsequent fixed assembly by bending the lead wire. This ensures the accuracy of the insertion and avoids bending and deformation of the lead wire during the preliminary fit.

[0052] Step S4: The material-pulling claw 434 in the drive transfer assembly 430 moves relatively away to complete the assembly process between the box and the main component by bending the lead wires. This step involves moving the material-pulling claw 434 in the drive transfer assembly 430 relatively away, using the force of the claw 434 to bend the two lead wires passing through the box. This bending creates a limiting structure on the lead wires, firmly connecting the main component to the box and completing the assembly process. This method of assembly by bending the lead wires eliminates the need for additional welding or fasteners, simplifying the assembly process and improving efficiency. Simultaneously, the bent lead wires form a stable connection structure, ensuring the electrical connection reliability of the junction box and preventing problems such as loose lead wires and poor contact during subsequent use, further improving product assembly quality and service life.

[0053] In summary, compared with current conventional assembly technologies, this application effectively solves the technical pain points of messy main lead wire posture and difficult plug-in alignment in traditional assembly methods, significantly improves the automation, accuracy and efficiency of junction box assembly, reduces product defect rate, and provides a reliable guarantee for efficient and stable automated mass production.

It is neither necessary nor possible to exhaustively list all possible implementations here.
