Description

Technical Field

[0001] This invention relates to the field of photovoltaic module production equipment technology, and in particular to a photovoltaic module frame assembly process for cleaning excess adhesive. Background Technology

[0002] After the photovoltaic module is framed, the sealant silicone at the four corners of the frame will overflow, forming excess adhesive. If the excess adhesive is not thoroughly and cleanly removed, it will not only affect the flatness of the photovoltaic module's appearance, but also cause residual adhesive and water accumulation in the frame bonding gaps. Long-term use can easily lead to quality problems such as module corrosion, seal failure, and module explosion. Therefore, accurate cleaning of excess adhesive after frame assembly is an indispensable key process in the photovoltaic module production process. At present, the industry has gradually abandoned the inefficient process of manually scraping and wiping off adhesive.

[0003] Patent No. CN202511352801.9 discloses a photovoltaic module adhesive removal device and method. The adhesive removal device of the device is equipped with an upper pressing mechanism, a lower pressing mechanism, and separate side and bottom adhesive removal mechanisms. By using upper and lower pressing positioning in combination with the side and bottom separate spraying adhesive removal and blowing dehumidification, the basic cleaning operation of the photovoltaic module frame corner adhesive is realized. To a certain extent, the adhesive removal is automated, replacing the traditional manual operation and improving the basic adhesive removal efficiency. However, it has the following defects: (1) It only relies on a single high-pressure spraying and simple blowing dehumidification. Moreover, the side and bottom cleaning mechanisms are separate and independent, resulting in high driving costs and inability to handle right-angle corners. (1) The corner composite area forms an all-round collaborative cleaning, with a large cleaning blind spot and poor adhesive removal quality stability; (2) The basic shielding and sealing is achieved by using a simple waterproof cover and glue plate. Only the upper and lower pressure are set, and the side pressure sealing is not set. During the cleaning operation, the high-pressure water mist is easy to overflow and penetrate from the gaps of the component frame and the work gap; (3) The blowing water removal operation is completed by a single jet head. The single wind force blowing is either too small to completely remove the fine water mist, or too large to cause water droplets to splash and secondary pollute the component surface; (4) No visual inspection is set before and after adhesive removal. It is impossible to accurately identify the overflow position before cleaning and to accurately re-inspect the adhesive removal effect and dryness after cleaning and drying.

[0004] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a photovoltaic module frame assembly overflow cleaning equipment and method. Summary of the Invention

[0017] A method for cleaning excess adhesive after photovoltaic module frame assembly, characterized by the following steps: S1. Conveying and Pre-inspection: The photovoltaic module with the frame completed is input into the component conveyor line, and the photovoltaic module is initially positioned by the block at its end. The first vision inspection mechanism (a) on both sides sequentially collects images of the right-angled side and bottom surface of the photovoltaic module to identify the position of glue overflow. S2, Alignment and Correction: The power mechanism drives the overflow cleaning mechanism to move to the right angle of the photovoltaic module, and the alignment component on the overflow cleaning mechanism performs alignment and correction on the photovoltaic module. S3, Sealing: The lower pressure unit, upper pressure unit and elastic side pressure unit of the sealing and water blocking device are fitted and sealed from the top, bottom and side of the photovoltaic module to form a closed cleaning chamber at the opening of the protective cover to prevent cleaning water mist and residual adhesive from overflowing. S4. High-pressure water spray and roller brush cleaning: The cleaning device drives the nozzles to extend into the working area. The first nozzle faces the bottom of the photovoltaic module, and the second nozzle faces the side of the photovoltaic module. High-pressure water spray is used to rinse the excess adhesive on the right-angle sides and bottom of the photovoltaic module. At the same time, the roller brush cleaning device drives the water wheel roller brush to extend into the working area. The roller brush with V-shaped brushes is driven by the water wheel to rotate continuously, and rotates to brush the stubborn residual adhesive at the right-angle corners of the photovoltaic module. The combination of high-pressure water rinsing and roller brush cleaning achieves all-round adhesive removal from the right angles of the photovoltaic module without dead angles. S5. Two-stage drying process: After cleaning, the first air blowing mechanism inside the overflow cleaning mechanism blows away large water droplets on the surface of the component, and the second air blowing mechanism at the output end of the component conveyor line further blows away residual water mist to complete the drying operation. S6. Wastewater Recycling: Wastewater generated during the cleaning process is collected by a water circulation mechanism. A pull-out water tray collects all the wastewater, which is filtered by an internal removable filter to remove colloidal debris, dust, and impurities. The wastewater is collected in a water collection tank through a fixed plate at the bottom of the water tray. The water collection tank supplies high-pressure water to the cleaning device through a high-pressure pump and normal-pressure water to the roller brush cleaning device through a normal-pressure pump, thus realizing the filtration and recycling of wastewater. S7. Post-inspection and discharge: The dried photovoltaic modules are conveyed along the module conveyor line. The camera of the second vision inspection mechanism (b) takes pictures to detect the glue removal effect and the drying effect. If residual glue or water stains are detected, the equipment will automatically alarm and manual secondary glue removal and repair will be carried out. The photovoltaic modules that pass the inspection will continue to be conveyed and discharged.

[0018] Compared with the prior art, the beneficial effects of the present invention are: The dual-sided high-pressure water spray cleaning device, combined with the central roller brush cleaning device, can simultaneously clean the right-angle sides, bottom surface, and corner blind areas of photovoltaic modules. High-pressure water jets wash away loose adhesive, and water flow drives the roller brush to peel off stubborn adhesive residue. The dual adhesive removal method can thoroughly remove solidified adhesive residue and solve the problem of incomplete cleaning. The system is equipped with three sets of sealing units: upper pressure, lower pressure, and elastic side pressure. These units, together with the protective cover, form a closed cleaning chamber, which completely seals the working gaps and provides a better sealing effect. This effectively prevents cleaning water mist and adhesive wastewater from splashing and seeping out. The system features a two-stage differentiated air blowing mechanism. The first stage uses low-power, angled air blowing to remove large water droplets and prevent splashing. The second stage uses high-power, spliced ​​air blades to remove fine water mist, achieving deep drying and completely resolving issues such as water stains and water mist residue on the frame. This also prevents oxidation of the component frame and secondary adhesion of the adhesive, ensuring the quality of the component encapsulation. Attached Figure Description

[0037] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0038] Please see Figures 1 to 17 The embodiments of the present invention include: A photovoltaic module frame overflow cleaning device includes a frame 1, a module conveyor line 2, a power mechanism 3, an overflow cleaning mechanism 4, a drying mechanism 5, a water circulation mechanism 6, and a visual inspection mechanism 7.

[0039] The frame 1 is equipped with a module conveyor line 2 for transporting photovoltaic modules. The photovoltaic modules are transported from the previous station to this cleaning equipment. The frame 1 is also equipped with a power mechanism 3, which drives four sets of overflow cleaning mechanisms 4 to move to the four right angles of the photovoltaic modules. The overflow cleaning mechanisms 4 clean the overflowing glue at the right angles of the photovoltaic modules. A drying mechanism 5 is installed inside the overflow cleaning mechanism 4 and on the frame 1 at the output end of the module conveyor line 2. A water circulation mechanism 6 is connected to the frame 1 below the overflow cleaning mechanism 4. The water circulation mechanism 6 provides cleaning water to the overflow cleaning mechanism 4 and recovers the cleaned liquid. A visual inspection mechanism 7 is provided at the input and output ends of the module conveyor line 2.

[0040] The component conveyor line 2 uses several synchronously connected belt conveyor lines. A blocking cylinder is installed at the end of the conveyor line. The blocking cylinder can drive the blocking wheel to extend, so as to achieve the initial positioning of the photovoltaic module.

[0041] The power mechanism 3 includes a transfer frame 31, a transmission adjustment unit 32, and a power unit 33. Two sets of transfer frames 31 are slidably mounted on the frame 1 along the X direction. The frame 1 is equipped with a transmission adjustment unit 32 that drives the two sets of transfer frames 31 to move synchronously (relatively or backward). A first overflow cleaning mechanism 4a is fixedly mounted on the side of the two sets of transfer frames 31 near the output end of the component conveying line 2. A second overflow cleaning mechanism 4b is slidably mounted on the side of the two sets of transfer frames 31 near the input end of the component conveying line 2. The second overflow cleaning mechanism 4b is driven by the power unit 33 to move toward the first overflow cleaning mechanism 4a along the Y direction.

[0042] The transmission adjustment unit 32 includes two synchronous pulleys 321 rotatably mounted on the frame 1, a belt 322 synchronously connecting the two synchronous pulleys 321, and a motor 323 driving one of the synchronous pulleys 321 to rotate. The left and right transfer frames 31 are respectively connected to the upper and lower belt surfaces of the belt 322 through belt pressure plates. When the belt is running, the two transfer frames 31 move closer to each other or move away from each other. It is compatible with long belts and can realize long-distance bilateral synchronous displacement operation.

[0043] The power unit 33 adopts a single-axis linear module or a belt conveyor structure like the one used in the transmission adjustment unit 32, which is compatible with short-specification belts and can realize short-distance unilateral displacement operations.

[0044] The four sets of adhesive overflow cleaning mechanisms 4 are two sets of first adhesive overflow cleaning mechanisms 4a near the output end of the module conveyor line 2 and two sets of second adhesive overflow cleaning mechanisms 4b near the input end of the module conveyor line 2. Each adhesive overflow cleaning mechanism 4 includes a base plate 41, cleaning devices 42, roller brush cleaning devices 43, a protective cover 44, a straightening component 45, and a sealing and water-blocking device 46. The base plate 41 is equipped with two sets of vertically distributed cleaning devices 42 and a set of roller brush cleaning devices 43 aligned with the right angle of the photovoltaic module. The roller brush cleaning device 43 is centrally arranged between the two sets of cleaning devices 42 and can cooperate with the two sets of cleaning devices 42 to respectively realize the adhesive overflow cleaning operation on the two right-angled sides, bottom surface, and right-angled corner of the photovoltaic module, thereby realizing the cleaning of the right-angled position of the photovoltaic module. For comprehensive cleaning, a protective cover 44 is installed on the base plate 41. The cleaning areas of the cleaning device 42 and the roller brush cleaning device 43 are located inside the protective cover 44, which can effectively prevent water stains and residual adhesive debris generated during the cleaning process from splashing out and avoiding pollution of the surrounding environment. Two sets of alignment components 45 are set on the outside of the protective cover 44, pointing to the side of the photovoltaic module respectively. One side of the protective cover 44 has an operating opening adapted to the right-angle insertion of the photovoltaic module, so that the right-angle part of the photovoltaic module can be inserted into the protective cover 44 to complete the cleaning operation. A sealing water-blocking device 46 is set around the operating opening to seal and block the gap between the photovoltaic module and the operating opening, preventing the overflow of cleaning water and residual adhesive water mist, and at the same time preventing water stains from seeping into the equipment and affecting the service life of the parts.

[0045] The cleaning device 42 includes a sliding cylinder 421, a push plate 422, a nozzle holder 423, a first nozzle 424, a second nozzle 425, a first baffle 426, and a second baffle 427. The sliding cylinder 421 is mounted on a base plate 41. A push plate 422 is mounted on the sliding surface of the sliding cylinder 421. A nozzle holder 423 is mounted on the push plate 422. The nozzle holder 423 moves synchronously with the push plate 422 and extends into the working area of ​​the protective cover 44. The nozzle holder 423 has a communicating cavity inside that can be connected to an external high-pressure water source. The head of the nozzle holder 423 is equipped with a first nozzle 424 that communicates with the internal cavity. A second nozzle 425, which is also connected to the internal cavity, is mounted on the upper part of the nozzle holder 423 facing the bottom surface of the photovoltaic module. The second nozzle 425 is positioned facing the side of the photovoltaic module and can simultaneously perform high-pressure water spraying to remove adhesive from the right-angled bottom and side surfaces of the photovoltaic module. A first baffle 426 is fixedly installed inside the protective cover 44 located at the side ends of the two sets of nozzles, and a second baffle 427 is fixedly installed at the tail of the nozzle holder 423. Through the cooperation of the first baffle 426 and the second baffle 427, the high-pressure water spray range can be effectively blocked and isolated, preventing the cleaning mist and residual adhesive from splashing around, and further improving the sealing and cleanliness of the working area.

[0046] The roller brush cleaning device 43 includes a push-pull cylinder 431, a mounting base 432, a drive shaft 433, a water wheel assembly 434, and a roller brush 435. The output end of the push-pull cylinder 431 is connected to the mounting base 432, which can drive the mounting base 432 to extend into the internal cleaning area of ​​the protective cover 44. The drive shaft 433 is rotatably mounted between the two side plates of the mounting base 432. The water wheel assembly 434 is mounted on the outer side of both side plates of the mounting base 432. The water wheel assembly 434 is connected to the end of the drive shaft 433, which can drive the drive shaft 433 to rotate continuously. A roller brush 435 is fixedly mounted in the middle of the drive shaft 433 between the two sets of water turbine components 434. The roller brush 435 rotates synchronously with the drive shaft 433. The outer circumference of the roller brush 435 has a V-shaped arrangement of brushes, forming a continuous V-shaped cleaning slope. During the rotation of the roller brush 435 with the drive shaft 433, it can perform rotational brushing on the right-angle corner of the photovoltaic module. Combined with the high-pressure water spray cleaning of the cleaning devices 42 on both sides, it can thoroughly remove stubborn excess adhesive residue and achieve all-round, dead-angle-free cleaning of the right-angle position of the photovoltaic module.

[0047] The water turbine assembly 434 includes a water turbine 4341 and a water turbine housing 4342. The water turbine housing 4342 is fixedly installed on the side plate of the mounting base 432. The inner side of the water turbine housing 4342 is recessed on the side facing the side plate of the mounting base 432 to form a water turbine cavity 4340. The water turbine 4341 is installed on the drive shaft 433 and housed inside the water turbine cavity 4340. The upper part of the water turbine housing 4342 has a water inlet that communicates with the water turbine cavity 4340 and is connected to atmospheric pressure water. The lower part of the water turbine housing 4342 has a water outlet that communicates with the water turbine cavity 4340 to facilitate the timely discharge of liquid from the cavity.

[0048] The water impeller 4341 has six blades 43411 evenly distributed on its circumferential wall. The blades 43411 have a rectangular curved blade structure. The outer rotation trajectory of the blades 43411 is in close fit with the inner wall of the water impeller cavity 4340, filling the internal space of the water impeller cavity 4340. The water flow impacts the water-facing surface of the rectangular curved blades 43411, and the impact force of the water flow generates a circumferential driving thrust, which drives the water impeller 4341 to rotate continuously around the axis of the drive shaft 433. The end of the water impeller 4341 near the roller brush 435 is integrally formed with a circular water-blocking part 43412. The circular water-blocking part 43412 is integrated with the end of each blade 43411, which can prevent the water flow in the water impeller cavity 4340 from splashing towards the roller brush 435, thus playing a role in blocking water and preventing water stains from contaminating the surface of the photovoltaic module to be cleaned.

[0049] The alignment component 45 includes an alignment cylinder 451 and an alignment wheel 452 extending from the alignment cylinder 451 to align the sides of the photovoltaic module. The two sets of alignment components 45 are respectively arranged on the two right-angled sides of the photovoltaic module. During operation, the two sets of alignment cylinders 451 extend synchronously, driving the alignment wheel 452 to push the two sides of the photovoltaic module at the same time, automatically aligning the photovoltaic module entering the work station, correcting the offset and skew of the photovoltaic module, ensuring that the right-angled part of the photovoltaic module is accurately aligned with the working opening of the protective cover 44, and ensuring accurate cleaning position.

[0050] The sealing and water-blocking device 46 includes a lowering unit 461 located below the component to be cleaned, an uppering unit 462 located above the component to be cleaned, and an elastic side-pressing unit 463 located on the side of the component to be cleaned.

[0051] Both the lowering unit 461 and the uppering unit 462 include a lowering cylinder 401 fixedly disposed relative to the protective cover 44, a pressure plate 402 extended by the lowering cylinder 401, and an elastic sealing element 403 installed on the pressure plate 402. The elastic sealing element 403 is preferably made of sponge, which has good elasticity and sealing performance. During the cleaning process, the lowering cylinder 401 drives the elastic sealing element 403 to extend and closely fit the upper and lower surfaces of the component to be cleaned, forming an effective seal and preventing cleaning water from being sprayed onto other non-cleaning areas of the component to be cleaned.

[0052] The elastic side pressure unit 463 includes a fixed base 4631, two movable blocks 4632 slidably disposed on the fixed base 4631, a waterproof top cover 4633 installed on the two movable blocks 4632, a limiting rod 4634 installed at the rear end of the movable blocks 4632, and a spring 4636 sleeved on the limiting rod 4634 and abutting against a limiting block 4635 located on the fixed base 4631. The waterproof top cover 4633 is located above the protective cover 44. Under the elastic force of the spring 4636, the waterproof top cover 4633 is always pressed towards the component to be cleaned. The waterproof top cover 4633 has a right-angle opening on the side near the component to be cleaned. A side pressure block 4637 is vertically installed at the right-angle opening. During the cleaning process, the two side pressure blocks 4637 always press the side of the component to be cleaned, forming a side seal. Together with the lower pressure unit 461 and the upper pressure unit 462, they form a complete sealed space, completely preventing cleaning water from splashing to the outside.

[0053] The drying mechanism 5 includes a first air blowing mechanism 51 disposed inside the protective cover 44 and a second air blowing mechanism 52 disposed above the output end of the module conveyor line 2. The first air blowing mechanism 51 is aimed at the bottom surface of the right angle of the module frame and blows off the large cleaning water droplets located on the bottom surface of the photovoltaic module. The second air blowing mechanism 52 is aimed at the right angle of the photovoltaic module and blows air from above with strong air force to remove water mist on the photovoltaic module. The second air blowing ensures the drying effect. The two stages work together to remove large water droplets first and then remove residual water mist, ensuring that the photovoltaic module frame is thoroughly dried and meets the cleanliness requirements of subsequent processing. The air force of the second air blowing mechanism 52 is greater than that of the first air blowing mechanism 51, ensuring that water mist can be completely blown away. The reasonable combination of the two air forces can avoid water droplets splashing due to excessive air force in the first stage and ensure that the air force in the second stage is sufficient to remove water mist.

[0054] The first air blowing mechanism 51 adopts a pressure plate 402 that is driven upward by a downward pressure cylinder 401 for sealing. The pressure plate 402 adopts a right-angle structure, which is adapted to the right-angle shape of the photovoltaic module. Two ventilation cavities 510 are opened in the horizontal direction inside its right-angle side. The two ventilation cavities 510 are connected to an external inflation device at their tail ends to realize the air source access. An air outlet slope 511 is set above the right-angle side of the pressure plate 402. Multiple air blowing holes 512 are arranged on the air outlet slope 511 and are connected to the ventilation cavities 510. Relying on the slope arrangement structure, the airflow is sprayed obliquely upward from the air blowing holes, which can accurately blow towards the bottom surface of the module frame, while avoiding the airflow directly impacting the frame and causing damage to the frame. At the same time, it effectively blows off the cleaning water droplets on the bottom surface. The inflation device here is configured with general airflow, which can blow off the large water droplets on the bottom surface of the right angle of the module frame, and the wind force requirement is low.

[0055] The second air blowing mechanism 52 includes an air knife body 521, an air inlet connector 522, a connecting ring 523, a sheet metal part 524, a connecting pin 525, a connecting block 526, a set screw 527, and a mounting bracket 528. The air knife body 521 is provided with a through cavity structure 520 along its length. The cavity structure 520 has a relatively large diameter. Multiple air inlets 5210 are arranged at equal intervals on the air knife body 521. The air inlets 5210 are connected to an external air source through the air inlet connector 522. The air knife body 521 is provided with a long strip-shaped air outlet 5211.

[0056] The two sets of air knife bodies 521 have compatible end structures, allowing for end alignment and splicing to achieve free length extension and facilitating flexible assembly of air knife components of different lengths according to operating conditions. The air knife body 521 has two docking sections at both ends, each with a docking groove. Adjacent docking grooves are connected by a connecting ring 523, and adjacent air knife bodies 521 are externally fixedly connected by sheet metal parts 524.

[0057] The air knife assembly, composed of multiple air knife bodies 521, has connecting pins 525 installed at both ends. The connecting pins 525 are fixed to the ends of the air knife assembly with bolts. A connecting block 526 is rotatably fitted on the outside of the connecting pin 525. The connecting block 526 has a through hole that matches the connecting pin 525. The connecting pin 525 can rotate freely in the through hole, thereby driving the air knife assembly to adjust the installation angle. This ensures that the air outlet 5211 of the air knife body 521 can be accurately aligned with the right angle of the assembly frame. A set screw 527 is threaded on one side of the connecting block 526. One end of the set screw 527 passes through the connecting block 526 and abuts against the outer wall of the connecting pin 525. After the installation angle of the air knife assembly is adjusted, the set screw 527 is manually tightened. The friction between the set screw 527 and the connecting pin 525 fixes the connecting pin 525, thereby fixing the installation angle of the air knife assembly and preventing angle deviation during operation from affecting the drying effect.

[0058] The connecting block 526 is fixed to the mounting bracket 528 by bolts. The mounting bracket 528 adopts an L-shaped structure, and its vertical part is provided with a waist-shaped hole 5280 for adjusting the installation height, thereby adjusting the height of the air knife assembly, adapting to the component frame of different thicknesses, ensuring that the distance between the air outlet 5211 and the component frame is reasonable, and improving the drying effect.

[0059] The water circulation mechanism 6 includes a water receiving tray 61, a filter 62, a fixed plate 63, and a water collection tank 64. The water receiving tray 61 is located below and synchronized with the overflow adhesive cleaning mechanism 4. The water receiving tray 61 adopts a pull-out structure and is installed below the overflow adhesive cleaning mechanism 4. The water receiving tray 61 has a built-in filter 62 for filtering impurities (such as dust, colloidal debris, etc.) in the cleaning wastewater. The filter 62 adopts a detachable filter screen structure, and the filter screen pore size is adapted to the size of impurities in the cleaning wastewater, taking into account both filtration effect and drainage efficiency, and is integrated with the water receiving tray. The tray 61 is compatible and can be pulled out together with the water receiving tray 61 for easy cleaning and replacement. A fixing plate 63 is installed on the frame 1 below the water receiving tray 61. The size design of the fixing plate 63 ensures that the entire movement stroke of the water receiving tray 61 is within its water receiving coverage area to avoid wastewater leakage. The filtered cleaning liquid collected by the fixing plate 63 is connected to the water collection tank 64 through a pipe. The water collection tank 64 pumps high-pressure water into the cleaning device 42 through a high-pressure pump. The water collection tank 64 also pumps normal-pressure water into the roller brush cleaning device 43 through a normal-pressure pump.

[0060] The water receiving tray 61 has several water outlets 610 at its bottom, and a handle 611 is installed on one outer side of the water receiving tray 61 for easy pushing and pulling by the operator. Mounting rails 612 are fixedly installed on both sides of the water receiving tray 61. The water receiving tray 61 is placed on the horizontal support portion of the two mounting rails 612 and can be slid along the horizontal support portion for easy pulling. When the filter 62 becomes saturated and its filtration efficiency decreases after a period of use, the operator does not need to disassemble the entire sealed water-blocking structure or other components. They only need to lift the handle 611 and manually pull out the water receiving tray 61 to quickly remove the filter 62 for cleaning or replacement, significantly reducing downtime for maintenance. The horizontal support portion of the mounting rails 612 has upward-bent limiting portions 613 at both ends. These limiting portions 613 can initially limit the water receiving tray 61 in the horizontal direction, preventing it from accidentally slipping off due to vibration or tilting during the movement of the treatment device. At the same time, it does not hinder the conscious removal of the tray during maintenance, thus balancing operational reliability and maintenance convenience.

[0061] A water collection tank 630 is provided on one side of the fixed plate 63. The water collection tank 630 is used to collect filtered wastewater. An opening is provided at the water collection tank 630, which is connected to the water collection tank 64 through a pipe, so as to realize the transportation of cleaning liquid from the fixed plate 63 to the water collection tank 64.

[0062] The visual inspection mechanism 7 is provided in four sets: a first visual inspection mechanism 7a set on both sides of the input end of the module conveyor line 2 and a second visual inspection mechanism 7b set on both sides of the output end of the module conveyor line 2. The first visual inspection mechanism 7a is used for pre-cleaning inspection, taking pictures of the right-angle side and bottom surface of the photovoltaic module to identify whether there is excess glue and the location that needs to be cleaned. The second visual inspection mechanism 7b is used for post-cleaning and drying inspection, taking pictures of the glue removal effect and the drying effect. If the glue removal is not thorough, the equipment alarms and manual secondary glue removal is required.

[0063] The visual inspection mechanism 7 includes an adjustment plate 71, an adjustment transfer frame 72, locking bolts 73, a camera 74, a camera bracket 75, a light source 76, a light source bracket 77, and a limiting post 78. The two adjustment plates 71 are mounted on the frame 1. The adjustment transfer frame 72 is slidably mounted on the adjustment plate 71 via a linear slide rail, allowing the adjustment transfer frame 72 to slide linearly along the length of the adjustment plate 71. The adjustment plate 71 has several adjustment holes 710 evenly spaced along the sliding direction. The adjustment transfer frame 72 is correspondingly equipped with locking bolts 73, which can be selectively screwed into the corresponding adjustment holes 710 to achieve adjustment. The sliding position of the transfer frame 72 is locked to adapt to the detection position requirements of photovoltaic modules of different specifications. Two sets of camera brackets 75 are fixedly installed on the horizontal extension end of the transfer frame 72. Cameras 74 pointing to the right-angle side and bottom of the photovoltaic module are installed on the camera brackets 75. A light source 76 is correspondingly installed at the lower end of each camera bracket 75. The light source 76 is fixed and angle adjustable through the light source bracket 77. Limiting posts 78 are installed on the adjustment plates 71 on both sides of the linear slide rail to limit the sliding stroke of the transfer frame 72, prevent it from sliding out of the slide rail, and ensure the safety and stability of the equipment operation.

[0064] The top plate of the camera bracket 75 has a central hole 751 for adjusting the camera mounting angle and an arc-shaped hole 752 with the central hole 751 as the center of rotation. The camera bracket 75 is assembled on the adjustment and transfer frame 72 by fasteners in conjunction with the central hole and the arc-shaped hole, which can realize the fine adjustment and positioning and locking of the camera mounting angle. After the two cameras 74 are assembled, they are arranged perpendicular to each other at right angles, which can simultaneously collect the appearance image information of the side and bottom of the photovoltaic module, and realize multi-angle visual inspection operation.

[0065] The light source bracket 77 is integrally equipped with a mounting part for supporting and installing the light source 76 and an angle adjustment part for fine-tuning the illumination angle of the light source. The two sets of angle adjustment parts are arranged perpendicular to the light source mounting part to ensure the stability and regularity of the angle adjustment. The angle adjustment part has a positioning hole 771 and an arc-shaped adjustment hole 772 with the positioning hole 771 as the center of rotation. Correspondingly, the two vertical mounting plates at the bottom of the camera bracket 75 have mounting holes that match the positioning hole 771 and the arc-shaped adjustment hole 772. During assembly and adjustment, the fastening screws pass through the positioning hole 771 and the arc-shaped adjustment hole 772 respectively and are locked in the mounting holes of the camera bracket 75. With the positioning hole 771 as the rotation fulcrum, and in conjunction with the arc-shaped adjustment hole 772, small-angle rotational fine-tuning of the light source bracket 77 and the light source 76 can be achieved. After the illumination angle of the light source is adjusted to the preset detection position, tightening the screws will complete the locking, ensuring the stability of the illumination angle of the light source, providing a uniform and suitable lighting environment for camera imaging, and effectively improving the accuracy and stability of the visual inspection of photovoltaic modules.

[0066] A method for cleaning excess adhesive after photovoltaic module frame assembly includes the following steps: S1. Conveying and Pre-inspection: The photovoltaic modules that have been assembled into frames are input by the module conveyor line 2. The blocking cylinder at the end of the module conveyor line 2 drives the blocking wheel to extend and perform initial positioning of the photovoltaic modules. The first vision inspection mechanism 7a on both sides sequentially collects images of the four right-angled sides and bottom surface of the photovoltaic modules to identify the location of glue overflow. S2, Alignment and Correction: The transmission adjustment unit 32 of the power mechanism 3 drives the two sets of transfer frames 31 to move relative to each other along the X-axis, and the power unit 33 drives the second overflow cleaning mechanism 4b to move towards the photovoltaic module along the Y-axis, so that the two sets of first overflow cleaning mechanisms 4a and the two sets of second overflow cleaning mechanisms 4b are precisely aligned with the four right-angle positions of the photovoltaic module; the correction components 45 of the four sets of overflow cleaning mechanisms 4 extend synchronously, and the correction and alignment of the photovoltaic module is completed through the correction wheel 452; S3. Sealing: The lower pressure unit 461, upper pressure unit 462 and elastic side pressure unit 463 of the sealing and water blocking device 46 are fitted and sealed from the upper, lower and side directions of the photovoltaic module, forming a closed cleaning chamber at the working opening of the protective cover 44 to prevent cleaning water mist and residual adhesive from overflowing. S4. High-pressure water spray and roller brush cleaning: The cleaning device 42 drives the nozzle to extend into the working area through the sliding cylinder 421. The first nozzle 424 faces the bottom of the photovoltaic module and the second nozzle 425 faces the side of the photovoltaic module. High-pressure water spray is used to wash the excess glue on the right-angle sides and bottom of the photovoltaic module. At the same time, the roller brush cleaning device 43 drives the roller brush 435 to extend into the working area. The atmospheric pressure water flow enters the water wheel assembly 434. The water flow impacts the curved blades 43411 of the water wheel 4341, driving the water wheel 4341 to rotate. This drives the transmission shaft 433 and the roller brush 435 with V-shaped brushes to rotate continuously, rotating and brushing the stubborn residual glue at the right-angle corners of the photovoltaic module. The combination of high-pressure water spraying and roller brushing achieves all-round glue removal from the right angles of the photovoltaic module without dead angles. S5. Two-stage drying process: After cleaning, the first air blowing mechanism 51 inside the overflow cleaning mechanism 4 dries the photovoltaic module once by relying on the pressure plate 402. The airflow is sprayed upward at an angle through the air blowing hole 512 on the air outlet slope 511 to blow away large residual water droplets on the bottom surface of the photovoltaic module with low wind force. The photovoltaic module is output with the module conveyor line 2. The second air blowing mechanism 52 above the output end works. The through-type cavity structure 520, together with the long strip-shaped air outlet 5211, outputs a large wind force and uniform airflow to blow the right-angle area of ​​the photovoltaic module in sequence, thoroughly removing residual fine water mist. The combination of two-stage air force, namely the front stage weak wind to prevent splashing and the rear stage strong wind to thoroughly dry, ensures that the photovoltaic module is dry and clean. S6. Wastewater Recycling: Wastewater generated during the cleaning process is collected by the water circulation mechanism 6. The pull-out water receiving tray 61 collects all the wastewater. The wastewater is filtered by the internal detachable filter 62 to remove colloidal debris, dust and impurities. The wastewater is collected through the water outlet 610 at the bottom of the water receiving tray 61 to the water collection tank 630 of the fixed plate 63 below, and finally introduced into the water collection tank 64. The water collection tank 64 supplies high-pressure water to the cleaning device 42 through a high-pressure pump and supplies normal-pressure water to the roller brush cleaning device 43 through a normal-pressure pump, realizing the filtration and recycling of wastewater. S7. Post-inspection and unloading: The dried photovoltaic modules are conveyed along the module conveyor line 2. The camera of the second vision inspection mechanism 7b accurately captures images of the right-angle side and bottom of the photovoltaic modules to detect the glue removal and drying effects. If residual glue or water stains are detected, the equipment will automatically alarm and manual secondary glue removal and repair will be performed. The qualified photovoltaic modules will be continuously conveyed and unloaded, completing the entire process of glue overflow cleaning after a single frame assembly.

[0067] This invention discloses a photovoltaic module frame assembly overflow cleaning device and method, which can thoroughly remove floating glue and stubborn residual glue from all right angles of the photovoltaic module; it is completely sealed to effectively prevent sewage splashing; the two-stage gradient air blowing drying structure can remove water in layers and dry thoroughly; and the front and rear dual-station visual inspection can realize precise cleaning of overflow glue and automatic re-inspection of cleaning quality.
