Description

Technical Field

[0001] This invention belongs to the field of photovoltaic module manufacturing technology, and in particular relates to a device and method for bending and labeling the high-temperature cloth lead wires of photovoltaic modules. Background Technology

[0002] In the process of applying high-temperature cloth to photovoltaic module leads, the high-temperature cloth needs to be precisely applied to the leads. Specifically, when the photovoltaic modules arrive, several sets of leads are in a vertical position. After applying the high-temperature cloth to the leads, the leads need to be bent horizontally to both sides to secure the cloth. After bending the leads, the label pasted on the outermost edge of the back of the photovoltaic module needs to be removed and then pasted onto the front of the photovoltaic module. Therefore, it is urgent to design a device that can not only perform the actions of picking up and placing the high-temperature cloth and bending the leads, but also remove the label from the back of the photovoltaic module and paste it onto the front of the photovoltaic module.

[0003] In the prior art, a photovoltaic module high-temperature cloth lead wire bending and labeling integrated device disclosed in Chinese utility model patent authorization announcement number CN222776538U can achieve the above-mentioned actions, including dispensing high-temperature cloth, bending the lead wire, and taking and re-labeling the label. However, the following problems still exist: (1) The high temperature cloth feeding module includes a first motor set on the frame, a moving frame that moves in the Y direction by the first motor, and several feeding boxes installed on the moving frame for placing high temperature cloth. The feeding boxes are provided with a pair of fixed rods that extend upward and can be inserted into the clearance holes of the high temperature cloth. A stack of high temperature cloth is placed on the fixed rods. When feeding, it is necessary to manually thread the high temperature cloth one by one onto the fixed rods, and then push the feeding box into the frame to perform the feeding action of high temperature cloth. In this scheme, the feeding efficiency of high temperature cloth is low and cannot meet the production requirements. In addition, it is necessary to arrange additional employees to thread the high temperature cloth, resulting in high production costs. (2) In this scheme, after the high temperature cloth is placed on the feeding box, the picking and bending mechanism will directly take out a single piece of high temperature cloth and place it on the lead wire of the photovoltaic module. If the positioning accuracy of the high temperature cloth in the feeding box is poor, the placement accuracy of the high temperature cloth will also be poor, which will reduce the quality of the placement of the high temperature cloth.

[0004] (3) The pick-up and bending mechanism includes a first XZ drive module, a first support plate driven by the first XZ drive module to move in the XZ direction, a high-temperature cloth pick-up and placement module fixed on the first support plate for picking up and placing high-temperature cloth, and a bending execution module located behind the high-temperature cloth pick-up and placement module for bending the leads on the photovoltaic module junction box. The alignment module is located in front of the high-temperature cloth pick-up and placement module. In this scheme, the first support plate is located on one side of the fifth motor, and the high-temperature cloth pick-up and placement module and the bending execution module are also located on one side of the first support plate. That is, the fifth motor, the first support plate, the high-temperature cloth pick-up and placement module and the bending execution module are stacked on one side in sequence. This design makes the width of the entire pick-up and bending mechanism wider, which is not conducive to the layout of the equipment in the width direction. Moreover, when the high-temperature cloth pick-up and placement module adsorbs the high-temperature cloth, it uses two suction cups to adsorb the high-temperature cloth. The effective area of ​​the suction cups is small, and the point adsorption method is easy to deform the high-temperature cloth layout part, affecting the placement accuracy of the high-temperature cloth.

[0005] Therefore, it is necessary to provide a device and method for bending and labeling photovoltaic module high-temperature cloth leads to solve the above-mentioned technical problems. Summary of the Invention

[0017] Compared with existing technologies, the beneficial effects of this invention—a photovoltaic module high-temperature cloth lead wire bending and labeling device and method—are as follows: This solution systematically solves the problems of low feeding efficiency, poor placement accuracy, wide equipment layout, and easy deformation of adsorption in existing technologies through highly automated disordered feeding, multi-level precise positioning, innovative lead wire alignment and bending structure, compact overall layout, and full-process visual quality inspection. It achieves efficient, high-precision, high-reliability, and intelligent production of the photovoltaic module back-end processing procedures. Specifically: 1. Significantly improves production efficiency and automation level, and reduces labor costs: The adoption of a disordered automatic feeding device (vibration material distribution + visual recognition + multi-axis material handling) realizes automatic, continuous, and batch feeding of high-temperature fabric, replacing the tedious process of manual fabric threading and feeding piece by piece in the existing technology, greatly improving feeding efficiency and meeting the needs of continuous and large-scale production; the material handling mechanism can be configured with multiple material handling modules, each of which can rotate independently, and multiple material handling modules can complete angle correction separately during the handling process; moreover, from the dispersion, identification, grasping, positioning, and transfer of high-temperature fabric to the final sleeve and bending, the entire process does not require manual intervention, reducing the dependence on dedicated material handling personnel and reducing production costs and labor burden; 2. Through multi-level precise positioning, the quality and accuracy of high-temperature cloth placement are greatly improved: A dedicated transfer positioning mechanism is set up to realize a secondary positioning mechanism for the high-temperature cloth. Before being gripped by the pick-and-place bending mechanism, the high-temperature cloth is precisely positioned by this mechanism, effectively eliminating the cumulative positioning error that may occur in the feeding process, and ensuring the positional accuracy and consistency when finally placed on the lead wire; The pick-and-place bending mechanism integrates an innovative bending module (a "trident" structure formed by the insert and the blade) and a straightening module, realizing precise control and straightening of the lead wire posture. Before the high-temperature cloth is put on, the two lead wires can be clamped and straightened on the left, right and front sides at the same time, forcibly ensuring that the lead wires are in an ideal vertical state, creating the necessary conditions for the accurate insertion of the high-temperature cloth, and fundamentally solving the problem of poor placement caused by the skewed lead wires; Adsorption blocks with multiple adsorption holes are used to replace the traditional single or double suction cups to achieve uniform surface adsorption of the high-temperature cloth, effectively avoiding deformation, wrinkles or displacement of the high-temperature cloth caused by local stress during the suction and transfer process, further ensuring placement accuracy; 3. Optimized structural layout, compact equipment and stable operation: By extending the fourth support plate of the second drive module downward to form the mounting part, and cleverly placing the pick-and-place module, bending module and straightening module on both sides and the same side of the mounting part, the structural innovation of the pick-and-place bending mechanism, this three-dimensional and compact layout, compared with the existing technology of stacking all functional modules in the horizontal direction, significantly reduces the size of the entire mechanism in the width direction, making the overall layout of the equipment more reasonable, saving the floor space, and also improving the balance and stability of the mechanism's movement.

Detailed Implementation

[0019] Please refer to Figures 1-17 This embodiment is a photovoltaic module high-temperature cloth lead bending and labeling device 100, which includes: Conveying mechanism 2, which is used to transport photovoltaic modules; The disordered automatic feeding device 1 is located on one side of the conveying mechanism 2. The disordered automatic feeding device 1 includes a feeding component 11, a vibrating material distribution component 12 connected to the output end of the feeding component 11, and a vision camera and material handling mechanism 14 located above the vibrating material distribution component 12. The pick-and-place bending mechanism 5 is disposed above the conveying mechanism 2, and the pick-and-place bending mechanism 5 is provided with at least one and connected to the movable end of the first drive mechanism 6. Transfer positioning mechanism 3 is set above the conveying mechanism 2 and located between the disordered automatic feeding device 1 and the pick-and-place bending mechanism 5; The suction and adhesive device 7 is located on one side of the conveying mechanism 2 and opposite to the disordered automatic feeding device 1. The suction and adhesive device 7 includes a second drive mechanism 71 and a suction and adhesive mechanism 73 connected to the movable end of the second drive mechanism 71.

[0020] The material handling mechanism 14 includes several material handling modules 143. Each material handling module 143 includes a lifting drive 1431, a first support plate 1432 driven by the lifting drive 1431 to perform lifting actions, a rotation drive 1433 disposed on the first support plate 1432, and a material handling assembly 1434 driven by the rotation drive 1433 to rotate around a vertical axis. The several material handling modules 143 are disposed on a second support plate 142, which is connected to the movable end of the first drive module 141. In this embodiment, the first drive module 141 is an XY axis drive module to drive the second support plate 142 to move along the XY direction. In this embodiment, three material handling modules 143 are provided, which can handle three high-temperature fabrics 200 at a time. In other embodiments, the number of material handling modules 143 can be adjusted according to actual conditions, and the number of material handling modules 143 is not limited here.

[0021] The material handling mechanism 14 is electrically connected to the vision camera. Based on the real-time posture recognition results of each piece of high-temperature fabric 200 by the vision camera, the mechanism 14 generates corresponding control commands for the movement of the second support plate 142 and the rotation of each material handling module 143, thus achieving unordered automatic material feeding. The vision camera not only identifies the posture of the high-temperature fabric 200 but also has defect detection capabilities, such as identifying damage, stains, and severe deformation of the high-temperature fabric through an image algorithm module. The image algorithm module is existing technology and can be designed using existing techniques; therefore, it will not be elaborated upon here.

[0022] The first drive module 141 includes a fifth motor 1411, a third drive shaft 1412 driven by the fifth motor 1411 to move along the Y direction, a third moving beam 1413 mounted on the third drive shaft 1412, and a sixth motor 1414 mounted on the third moving beam 1413. The second support plate 142 is driven by the sixth motor 1414 to move along the X direction. Third gears 1415 are provided at both ends of the third drive shaft 1412, and a third rack that meshes with the third gears 1415 is provided on the frame, meaning the third drive shaft 1412 can move horizontally along the Y direction on the frame.

[0023] The material handling assembly 1434 includes a material handling block 14341 disposed at the output end of the rotary drive 1433 and a second suction cup 14342 disposed at the bottom of the material handling block 14341. The material handling block 14341 has an adsorption hole communicating with the second suction cup 14342. A clearance opening 14343 is provided in the middle of the material handling block 14341. When the material handling assembly 1434 places the high-temperature cloth onto the transfer mechanism, it can avoid the positioning piece on the transfer mechanism. The transfer mechanism and positioning piece are prior art; refer to the transfer mechanism and positioning piece disclosed in Chinese Invention Patent Application Publication No. CN117985499A, which discloses a high-temperature cloth feeding device and feeding method, for details not provided here. Furthermore, the clearance opening 14343 further reduces the weight of the material handling block 14341, reducing the motion load on the rotary drive 1433, enabling it to achieve higher movement speed and acceleration.

[0024] The vibrating material distribution assembly 12 includes a first vibrating plate 121 and a first vibrating module 122 disposed at the bottom of the first vibrating plate 121. The feeding assembly 11 includes a second vibrating plate 111, a second vibrating module 112 disposed at the bottom of the second vibrating plate 111, and a discharge guide plate 113 connected to the output end of the second vibrating plate 111. The discharge guide plate 113 extends into the upper part of one side of the first vibrating plate 121. A waste collection box 123 is disposed on one side of the first vibrating plate 121. A material blocking assembly 124 is disposed at one end of the first vibrating plate 121 near the waste collection box 123. The material blocking assembly 124 includes a material blocking plate 1241 and a material blocking cylinder 1242 for driving the material blocking plate 1241 to perform lifting and lowering actions. In the initial state, the baffle plate 1241 is in a low position and the bottom of the baffle plate 1241 contacts the bottom wall of the first vibrating plate 121, preventing the high-temperature cloth in the first vibrating plate 121 from falling out. If the vision camera detects that the remaining high-temperature cloth in the first vibrating plate 121 is unqualified, the baffle cylinder 1242 drives the baffle plate 1241 to rise, and the baffle plate 1241 is in a high position. At this time, a discharge gap is formed between the bottom of the baffle plate 1241 and the bottom wall of the first vibrating plate 121, and the height of the discharge gap is consistent with the thickness of a single piece of high-temperature cloth 200. The first vibration module 122 drives the first vibrating plate 121 to vibrate, which enables the unqualified high-temperature cloth in the first vibrating plate 121 to enter the waste collection box 123.

[0025] The workflow of the disordered automatic feeding device 1 is as follows: First, the high-temperature cloth 200 is poured into the second vibrating plate 111. The second vibration module 112 drives the second vibrating plate 111 to vibrate and convey the high-temperature cloth 200 out. The high-temperature cloth 200 falls from the discharge guide plate 113 into the first vibrating plate 121. After being vibrated by the first vibration module 122, the high-temperature cloth 200 in the first vibrating plate 121 is dispersed into individual high-temperature cloths 200. Then, a vision camera takes pictures of the high-temperature cloth 200 in the first vibrating plate 121 for inspection and positions the high-temperature cloth 200 that meets the material picking requirements. Then, the material picking and conveying mechanism 14 starts to work, and the first drive module 141... The system moves several material-picking modules 143 above the high-temperature cloth. These modules can work simultaneously or sequentially. The lifting drive 1431 drives the first support plate 1432 to pick up the high-temperature cloth using the material-picking assembly 1434. Simultaneously, the rotation drive 1433 rotates the high-temperature cloth according to the received control command, ensuring that the high-temperature cloths 200 are aligned. After all the high-temperature cloths have been picked up, the first drive module 141 moves the material-picking modules 143 above the transfer positioning mechanism 3. The material-picking modules 143 then place the high-temperature cloths onto the transfer positioning mechanism 3, completing the feeding action of the high-temperature cloths 200.

[0026] The conveyor mechanism 2 is a belt conveyor line. Specifically, the conveyor mechanism 2 is driven by a servo motor and has four belts arranged in parallel at intervals. Due to the large length and width dimensions of the photovoltaic modules, in order to ensure the stability of the support, several sets of support wheels 22 are provided in the middle and on the side plates of the conveyor mechanism 2. Specifically, the several sets of support wheels 22 are arranged between the belts and on the sides of the belts, and each set of support wheels 22 is arranged on the support rod 21. A straightening mechanism is arranged around the conveyor mechanism 2. The straightening mechanism includes a blocking wheel 23 to prevent the photovoltaic modules from continuing to be conveyed forward, a rear straightening wheel 24 to straighten the rear of the photovoltaic modules, a left straightening wheel 25 to straighten the left side of the photovoltaic modules, and a right straightening wheel 26 to straighten the right side of the photovoltaic modules. The blocking wheel 23 can move up and down, the rear straightening wheel 24 can move horizontally and move up and down, and the left straightening wheel 25 and the right straightening wheel 26 can move horizontally to move closer to each other or further away from each other to achieve the straightening action on both sides of the photovoltaic modules. The straightening mechanism is existing technology and the design of the existing technology can be used, so it will not be described in detail here.

[0027] The transfer positioning mechanism 3 includes a third support plate 31 disposed above the conveying mechanism 2, a linear drive 32 disposed on the third support plate 31, a transfer plate 33 driven by the linear drive 32 to move perpendicular to the conveying direction of the conveying mechanism 2, and a plurality of positioning seats 34 disposed on the transfer plate 33 in an adjustable position. The plurality of positioning seats 34 are arranged along the conveying direction of the conveying mechanism 2. The linear drive 32 can drive the plurality of positioning seats 34 to move to the side of the disordered automatic feeding device 1 to receive the high-temperature cloth 200, and can also drive the plurality of positioning seats 34 to move to the side of the pick-and-place bending mechanism 5, so that the pick-and-place bending mechanism 5 can remove the high-temperature cloth 200 from the positioning seats 34. The positioning seat 34 includes a base plate 341 that is adjustablely disposed on the third support plate 31 and a pair of support blocks 342 disposed opposite to each other on the base plate 341. The distance between the two support blocks 342 is adjustable, and a first suction cup 345 is provided on the upper surface of each support block 342. Guide blocks 343 are detachably disposed on the inner sides of the two support blocks 342. A guide member 344 extends from the middle of the upper end of each guide block 343, which is higher than the upper surface of the support block 342. The two guide members 344 can be inserted into the two clearance holes 201 of the high temperature cloth 200 to achieve secondary positioning of the high temperature cloth 200, so as to ensure the accuracy of the placement of the high temperature cloth 200.

[0028] In this embodiment, three positioning seats 34 are provided to position three high-temperature cloths 200. This means that three leads 300 spaced apart on the photovoltaic module require the use of high-temperature cloths 200. The positions of the positioning seats 34 are adjustable to accommodate leads 300 with different spacing. Specifically, the position of the base plate 341 on the third support plate 31 is adjustable. The third support plate 31 has multiple sets of first mounting holes. The base plate 341 is selectively positioned into one set of first mounting holes using first fasteners, thus enabling the positioning seats 34 to be adjusted. In other embodiments, the number of positioning seats 34 can be set according to actual conditions and is not limited here. The base plate 341 is provided with a sliding groove 3412, and two bearing blocks 342 are adjustablely positioned within the sliding groove 3412. The base plate 341 is provided with multiple sets of second mounting holes, and the bearing blocks 342 are provided with oblong holes 3421. The bearing blocks 342 are selectively positioned into one set of second mounting holes by means of second fasteners, thus enabling position adjustment of the bearing blocks 342. This allows for the adaptation of high-temperature cloths with different spacing clearance holes 201, providing greater flexibility. The guide block 343 and guide member 344 are integrated, and the guide member 344 is similar in shape to the clearance holes 201 of the high-temperature cloth 200. The guide block 343 and guide member 344 are detachably mounted inside the bearing block 342. If a high-temperature cloth with a different structure is replaced, the corresponding guide block 343 and guide member 344 can be replaced, providing even greater flexibility. The first and second fasteners are bolts, pins, or screws.

[0029] To ensure the stability of the transfer plate 33's movement, a slide rail 35 is provided on the third support plate 31. The slide rail 35 is perpendicular to the conveying direction of the conveying mechanism 2, and the transfer plate 33 is slidably mounted on the slide rail 35 via a slider 36. A mounting bracket 37 is provided on the third support plate 31, and the mounting bracket 37 is connected to the frame at both ends. That is, the transfer positioning mechanism 3 is connected to the frame and located above the conveying surface of the conveying mechanism 2. When the photovoltaic module flows into the conveying mechanism 2, the third support plate 31 is located above one side of the photovoltaic module. The photovoltaic module's lead wire 300 is generally in the middle of the photovoltaic module, which does not affect the bending action of the high-temperature cloth 200 and the lead wire. The transfer positioning mechanism 3 is located above the conveying surface of the conveying mechanism 2. This arrangement can minimize the width of the entire equipment and reduce the space occupied by the equipment.

[0030] The pick-and-place bending mechanism 5 includes a second drive module 51 and a fourth support plate 52 connected to the movable end of the second drive module 51. The mounting portion 521 at the lower end of the fourth support plate 52 extends below the bottom of the second drive module 51. The mounting portion 521 is equipped with a pick-and-place module 53, a bending module 54, and a straightening module 55. The pick-and-place module 53 and the bending module 54 are located on opposite sides of the mounting portion 521, and the pick-and-place module 53 and the straightening module 55 are located on the same side of the mounting portion 521, with the pick-and-place module 53 positioned between the bending module 54 and the straightening module 55. By extending the mounting portion 521 downwards, the pick-and-place module 53, the bending module 54, and the straightening module 55 are rationally arranged on both sides of the mounting portion 521, significantly reducing the width of the entire mechanism, resulting in a compact and balanced structure, and facilitating the overall layout and stable movement of the equipment. In this embodiment, the second drive module 51 is an XZ axis drive module, which can drive the fourth support plate 52 to move in the XZ direction.

[0031] The pick-and-place module 53 is used to pick up and place the high-temperature cloth 200. The pick-and-place module 53 includes a first motor 531 disposed on one side of the mounting part 521, a lifting plate 532 driven by the first motor 531 to move up and down, and an adsorption block 533 connected to the bottom of the lifting plate 532. The bottom of the adsorption block 533 is provided with a number of adsorption holes. Compared to the high-temperature cloth picking and placing module in the photovoltaic module high-temperature cloth lead wire bending and labeling integrated device disclosed in Chinese Utility Model Patent Publication No. CN222776538U, this solution uses a first motor 531 to replace the cylinder in that solution. This allows for precise control of the lifting position and speed of the adsorption block 533, making it more adaptable and eliminating the need to adjust air pressure or worry about air pressure fluctuations. In the previous solution, a pair of suction cups at the lower end of the picking and placing rod may only adsorb the high-temperature cloth at one or two points. Point adsorption may cause uneven adsorption for soft or large high-temperature cloths. The adsorption block 533 in this solution has multiple adsorption holes at the bottom, which is equivalent to surface adsorption or line adsorption. The adsorption force is evenly distributed, and the high-temperature cloth is less likely to fall off or wrinkle, thus improving the placement accuracy of the high-temperature cloth.

[0032] After the loading and unloading module 53 places the high-temperature cloth 200 onto the lead wire 300, the bending module 54 bends the lead wire 300 to secure the high-temperature cloth 200. The bending module 54 includes a mounting plate 546 connected to the bottom of the mounting part 521 and extending to the other side, a slide cylinder 541 disposed at the bottom of the mounting plate 546, a first cylinder 542 and a second cylinder 544 disposed on the slide plate of the slide cylinder 541, a pair of levers 543 driven by the first cylinder 542 to open or close, and a pin 545 driven by the second cylinder 544 to extend or retract. The mounting plate 546 and the first motor 531 are located on opposite sides of the mounting part 521. A clearance space 522 is provided between the mounting plate 546 and the bottom of the second drive module 51 to allow the mounting part 521 to move up and down, facilitating the loading and unloading of the high-temperature cloth 200. When the pin 545 extends, a pair of levers 543 open, with the pin 545 positioned between them. When the pin 545 is inserted between the two leads, the levers 543 press against both sides of the lead. The two levers 543 and the pin 545 work together to form a trident-like arrangement, clamping the two leads together. This ensures that each lead 300 has a pin 545 and a lever 543 positioned on both sides, guaranteeing the lead 300 is vertical and facilitating the placement of the high-temperature fabric 200, thus improving placement accuracy. The pin 545 and the levers 543 are at the same height and are inserted into the lead simultaneously, ensuring insertion accuracy. If the insertion end of the pin 545 is not at the same height as the working end of the pair of levers 543, the lead wire will bend to one side and cannot be guaranteed to be vertical. Therefore, in this solution, the insertion end of the pin 545 is at the same height as the working end of the pair of levers 543, which can further ensure that the lead wire is vertical and avoid bending to one side, thereby improving the accuracy of high temperature cloth placement.

[0033] The alignment module 55 can simultaneously align two leads 300. The alignment module 55 includes a movable frame 551, an alignment plate 552 connected to the bottom of the movable frame 551 and extending horizontally towards the adsorption block 533, a support shaft 554 located at the top of the movable frame 551, and a third cylinder 553 that drives the support shaft 554 to extend or retract. When the third cylinder 553 drives the support shaft 554 to extend or retract, it moves the alignment plate 552 away from or towards the pick-and-place module 53. To ensure the stability of the movable frame 551's movement, a linear bearing 555 is provided on the mounting part 521. The support shaft 554 is movably mounted within the linear bearing 555 to ensure the stability of the support shaft 554's movement, thereby ensuring the stability of the movable frame 551. Ultimately, the alignment plate 552 simultaneously abuts against the sides of both leads 300, aligning all leads 300 simultaneously to ensure the accuracy of the high-temperature cloth. The pin 545, a pair of levers 543, high-temperature cloth 200, lead wire 300, and the alignment plate 552 are all aligned on the same straight line to ensure operational accuracy. The third cylinder 553 is located on the top surface of the mounting plate 546, the slide cylinder 541 is located on the bottom surface of the mounting plate 546, and the first motor 531 is located on the mounting part 521. The first motor 531 and the third cylinder 553 are located on opposite sides of the mounting part 521. The rational layout of each driving component (cylinder or motor) makes the entire structure more compact.

[0034] The mobile frame 551 is equipped with a first camera and a second camera. The first camera is tilted to the horizontal plane and aligned with the bottom of the adsorption block 533, while the second camera is aligned with the bending station, specifically with the lead wire. Both the first and second cameras are connected to an image recognition module, which is used to identify and determine the quality of the photos taken by the first and second cameras. The image recognition module is existing technology and its design is sufficient, so it will not be elaborated further here. The first camera is used to photograph and detect the high-temperature cloth 200 at the bottom of the adsorption block 533, checking for any abnormalities in the posture of the high-temperature cloth 200, specifically checking for wrinkles, curling, or bending. If any abnormality is detected, an alarm is triggered. The second camera is used to photograph and detect the posture of the lead wire 300, checking for any abnormalities in the posture of the lead wire 300, specifically checking for bending, breakage, or other abnormalities. If any abnormality is detected, an alarm is triggered.

[0035] The working process of the pick-and-place bending mechanism 5 is as follows: the second drive module 51 drives the fourth support plate 52 to move the pick-and-place module 53 to pick up the high-temperature cloth. A piece of high-temperature cloth 200 is adsorbed at the bottom of the adsorption block 533. After the high-temperature cloth is picked up, the second drive module 51 drives the fourth support plate 52 to move and moves the pick-and-place module 53 to directly above the lead wire 300. The first cylinder 542 of the bending module 54 drives a pair of levers 543 to open. Then the second cylinder 544 drives the insert pin 545 to extend forward into the middle of the pair of open levers 543. The pair of levers 543 and the insert pin 545 form a trident shape, and the slide cylinder 541 drives the pair of levers 543 and the insert pin to move together. At the same time, pin 545 extends into the two leads 300. At this time, pin 545 is inserted between the two leads, and a pair of levers 543 press against the left and right sides of the leads respectively. That is, each lead 300 has pin 545 and lever 543 positioned on both sides, so that the lead 300 is opened and kept in a vertical state, so that the high-temperature cloth 200 can be accurately fitted onto the lead 300. The high-temperature cloth 200 is provided with a clearance hole 201 for the lead 300 to pass through. At the same time, the third cylinder 553 drives the straightening plate 552 to move to one side of the lead, blocking the front side of the lead 300 to straighten the front side of the lead 300. That is, the left and right and front positions of the lead are straightened at the same time. To ensure the lead wire is vertical, after alignment, the third cylinder 553 drives the alignment plate 552 to extend forward and reset. The first motor 531 of the pick-and-place module 53 drives the adsorption block 533 to move downward, thus allowing the high-temperature cloth 200 to be fitted onto the upper end of the lead wire 300. The slide cylinder 541 drives a pair of levers 543 and pins 545 to retract backward simultaneously. The first motor 531 of the pick-and-place module 53 drives the adsorption block 533 to continue moving downward, thus fully fitting the high-temperature cloth 200 into place. The second cylinder 544 drives the pins 545 to retract backward. At the same time, the slide cylinder 541 drives the first cylinder 542 to extend forward, and the first cylinder 542 drives a... The pair of blades 543 move towards the center and are simultaneously inserted between the two leads 300. After being inserted between the two leads 300, the first cylinder 542 drives the pair of blades 543 to open to the left and right to bend the leads 300. The second cylinder 544 drives the pin 545 to extend forward and be positioned between the two leads 300. The second drive module 51 drives the fourth support plate 52 to move downward, so that the pair of blades 543 and the pin 545 act on the leads 300, thereby changing the leads 300 from a vertical state to a horizontal state. At the same time, the horizontal leads 300 fix the high-temperature cloth 200, completing the bending action of the high-temperature cloth 200 and the leads 300.

[0036] The first drive mechanism 6 includes a second motor 61, a first transmission shaft 62 driven by the second motor 61 to move along the Y direction, a first moving beam 63 mounted on the first transmission shaft 62, and several pick-and-place bending mechanisms 5 movably mounted on the first moving beam 63. The two ends of the first transmission shaft 62 are provided with first gears 64, and the frame is provided with a first rack that cooperates with the first gears 64, that is, the first transmission shaft 62 can move horizontally along the Y direction on the frame.

[0037] The suction and adhesive device 7 is used to remove the label pasted on the outermost edge of the back of the photovoltaic module and then paste it onto the front edge of the photovoltaic module. The second drive mechanism 71 includes a third motor, a second drive shaft 712 driven by the third motor to move in the Y direction, and a second moving beam 713 disposed on the second drive shaft 712. The suction and adhesive device 73 is movably disposed on the second moving beam 713. The two ends of the second drive shaft 712 are provided with second gears 714, and the frame is provided with a second rack that cooperates with the second gears 714, that is, the second drive shaft 712 can move horizontally in the Y direction on the frame.

[0038] The label-collecting and pasting mechanism 73 includes a third drive module 731 mounted on a second moving beam 713, a fifth support plate 732 driven by the third drive module 731 to move along the XZ direction, a fourth motor 733 fixed on the fifth support plate 732, a sixth support plate 734 driven by the fourth motor 733 to rotate around the Z-axis, a fourth cylinder 735 fixed on the sixth support plate 734, a suction rod 736 driven by the fourth cylinder 735 to rotate around a horizontal axis and used for collecting and pasting labels, a pressing assembly 737 fixed on the sixth support plate 734 and located above and behind the suction rod 736, and a camera module 738 mounted above and to one side of the suction rod 736 and used for detecting the label position. The third drive module 731 is an XZ-axis drive module to drive the fifth support plate 732 to move along the XZ direction. The fourth motor 733 drives the sixth support plate 734 to rotate the suction rod 736 around the Z-axis, allowing adjustment of the label application direction to accommodate labels in different orientations and improve versatility. The structure and working principle of the suction and pasting mechanism 73 can be found in the "Integrated Device for Bending and Labeling High-Temperature Cloth Lead Wires of Photovoltaic Modules" disclosed in Chinese Utility Model Patent Publication No. CN222776538U, and will not be elaborated upon here.

[0039] This embodiment also provides a method for bending and labeling the high-temperature discharge cloth leads of photovoltaic modules, which is based on the above-mentioned photovoltaic module high-temperature discharge cloth lead bending and labeling equipment 100, and includes the following steps: Step S1: The photovoltaic module flows into the conveying mechanism 2, and at the same time, a stack of high-temperature cloth 200 is placed into the feeding component 11. The feeding component 11 conveys the high-temperature cloth 200 to the vibrating material distribution component 12. The vibrating material distribution component 12 disperses the stacked high-temperature cloth 200 into individual pieces of high-temperature cloth 200. Step S2: The vision camera takes pictures of the high-temperature cloth 200 dispersed into individual pieces for inspection, and the material handling mechanism 14 transports the qualified high-temperature cloth 200 to the transfer positioning mechanism 3 to achieve secondary positioning of the high-temperature cloth 200. Step S3: The first driving mechanism 6 drives the pick-and-place bending mechanism 5 to move to the transfer positioning mechanism 3, and the pick-and-place bending mechanism 5 adsorbs the high-temperature cloth 200 on the transfer positioning mechanism 3; Step S4: The first driving mechanism 6 drives the picking and placing bending mechanism 5 to move to the lead wire 300 of the photovoltaic module. The picking and placing bending mechanism 5 passes the high temperature cloth 200 onto the lead wire 300 and bends the lead wire 300 from a vertical state to a horizontal state. Step S5: While performing steps S3 to S4, the suction and pasting device 7 moves to the side of the photovoltaic module, and the suction and pasting mechanism 73 removes the label from the outermost edge of the back of the photovoltaic module and pastes the label to the front of the photovoltaic module.

[0040] After steps S3 to S5 are completed, the photovoltaic module flows out of the conveying mechanism 2 and continues to perform the actions of high-temperature cloth, lead wire bending, and labeling on the next photovoltaic module.
