Description

Technical Field

[0001] This invention relates to the field of photovoltaic module automation equipment technology, and in particular to a mechanism for cleaning excess adhesive from the corners of photovoltaic module frames. Background Technology

[0002] The four-sided aluminum frame of a photovoltaic panel serves to support and protect the internal solar cells and glass cover. During installation, solar fluid sealant is used to bond and seal adjacent aluminum frames. Currently, the assembly process for aluminum frames typically employs a four-sided extrusion method. Under mechanical pressure, the aluminum frame bonds to the module, and the sealant is fully filled into the assembly gaps. However, due to the high extrusion pressure, excess sealant inevitably squeezes out from the joints between adjacent aluminum frames, resulting in excess sealant.

[0003] Excessive adhesive can affect the aesthetics and overall quality of photovoltaic panels. Current methods for cleaning excess adhesive often involve manual labor: The first method involves workers using cloths, scrapers, or other cleaning tools to clean the solar fluid sealant from the gaps. This manual cleaning method is not only labor-intensive and requires cleaning tools, but also, if not cleaned in time, the excess adhesive can solidify and become difficult to remove. If workers use too much force, there is a risk of scratching the frame or the surface of the photovoltaic panel glass, leading to poor product quality. The second method is a semi-automated mechanical scraping device, which often uses a robotic arm to drive brushes, scrapers, and other cleaning tools to scrape and polish the edges. This method also has the problem of consuming cleaning tools and makes it difficult to guarantee the stability of product quality.

[0004] Therefore, the present invention provides a mechanism for cleaning excess adhesive from the corners of photovoltaic module frames, in order to solve the problems of low efficiency, unstable cleaning effect, and large amount of cleaning consumables in the prior art for manually cleaning excess adhesive from photovoltaic module frames. Summary of the Invention

[0005] The purpose of this invention is to provide a mechanism for cleaning excess adhesive from the corners of photovoltaic module frames, in order to solve the problems of low efficiency, unstable cleaning effect, and large amount of cleaning consumables in the existing technology for manually cleaning excess adhesive from photovoltaic module frames.

[0006] The technical solution of this invention is: a mechanism for cleaning excess adhesive from the corners of a photovoltaic module frame, comprising: A sealing unit includes a sealing mechanism for sealing the corner of a photovoltaic panel frame. The sealing mechanism is configured to be able to contact or detach from the corner of the photovoltaic panel frame. After the sealing mechanism is in contact with the end face of the corner of the photovoltaic panel frame, it can form a closed cleaning cavity on the outside of the photovoltaic panel frame. After the sealing mechanism is detached from the end face of the corner of the photovoltaic panel frame, the photovoltaic panel can be moved into or out of the cleaning cavity. The cleaning unit is located inside the cleaning chamber and includes two sets of high-pressure water jet rinsing mechanisms located on both sides of the adjacent frame of the photovoltaic panel. The two sets of rinsing mechanisms are configured to move towards or away from each other and spray water jets inside the cleaning chamber to rinse the colloid on the corner of the photovoltaic panel frame.

[0007] Preferably, the cleaning unit includes a fourth drive mechanism that drives the first mounting base and the second mounting base to move, and both the first mounting base and the second mounting base carry a nozzle; The two sets of rinsing mechanisms include a first rinsing mechanism and a second rinsing mechanism. The first rinsing mechanism is a combination of the first mounting base carrying the nozzle, and the second rinsing mechanism is a combination of the second mounting base carrying the nozzle. The fourth driving mechanism drives the first rinsing mechanism and the second rinsing mechanism to move synchronously towards or away from each other.

[0008] Preferably, the fourth driving mechanism includes a driving device and a conveying mechanism. The driving power source drives the conveying mechanism, and the driving device drives the conveying mechanism to drive the first rinsing mechanism and the second rinsing mechanism. The conveying mechanism includes a driving wheel, a driven wheel assembly, and a conveyor belt connected to the output end of the driving device. The first mounting base and the second mounting base are fixedly connected to the conveyor belt and are configured to drive the first mounting base and the second mounting base to move synchronously towards or away from each other along the right-angle side of the adjacent frame of the photovoltaic panel when the conveyor belt is running.

[0009] Preferably, the sealing mechanism includes an upper sealing assembly that seals the photovoltaic panel frame from above, a lower sealing assembly that seals the photovoltaic panel frame from below, and two sets of side sealing assemblies that seal adjacent sides of the photovoltaic panel frame.

[0010] Preferably, the upper sealing assembly includes a first driving mechanism, the output end of the first driving mechanism drives downward and is connected to an upper sealing plate, and a first flexible sealing layer is fixedly connected below the upper sealing plate; The lower sealing assembly includes a second driving mechanism, the output end of which drives upward and is connected to a lower sealing plate, and a second flexible sealing layer is fixedly connected above the lower sealing plate; The side sealing assembly includes a third driving mechanism that drives the photovoltaic panel towards the frame and is connected to a side sealing plate.

[0011] Preferably, it also includes a drying unit, which is located downstream of the cleaning unit, and is used to blow away and dry the residual water when the photovoltaic panel is removed after cleaning. The drying unit includes a side air blower mechanism located on the side of the photovoltaic panel frame and a bottom air blower mechanism located below the photovoltaic panel.

[0012] Preferably, the side air blower mechanism includes a side air blade for drying, which is fixedly mounted on a first fixed frame; the bottom air blower mechanism includes a bottom air blade for drying, which is fixedly mounted on a second fixed frame; and the air outlets of the side air blade and the bottom air blade face the side and bottom of the frame corner of the photovoltaic panel, respectively.

[0013] Preferably, it further includes a housing, in which the sealing unit, the cleaning unit and the drying unit are all housed.

[0014] Preferably, a perforation is provided at the bottom of the outer casing, through which cleaning water and colloids that have been washed away fall.

[0015] Preferably, the cleaning mechanism is configured in four groups, corresponding to the four corners of the photovoltaic panel respectively. The four groups of cleaning mechanisms are connected to a common circulating water system, which recycles and filters wastewater and provides rinsing water. The four groups of cleaning mechanisms are configured to move relative to the photovoltaic panel to achieve clamping and releasing actions on the photovoltaic panel.

[0016] Compared with the prior art, the advantages of the present invention are: (1) By setting a sealing unit consisting of the top, bottom and adjacent sides, a closed cleaning chamber is formed by sealing a single corner of the photovoltaic panel frame. The adhesive on the corner of the photovoltaic panel frame is rinsed by the cleaning unit. After cleaning, it is dried by the air drying unit, realizing fully automated cleaning work, replacing the traditional manual or semi-automated cleaning. (2) By setting up a flushing mechanism that can move synchronously in opposite directions or in opposite directions, and by spraying high-pressure water jets from the nozzle to form a "water jet" that impacts each other, the overflow glue can be flushed in an all-round and high-intensity manner, thereby ensuring the thoroughness and consistency of the cleaning effect. (3) By setting up a high-pressure water rinsing method and a circulating water system, the wastewater after rinsing can be collected and reused, while avoiding the use of cleaning consumables, which is more environmentally friendly.

[0018] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1 to 7 As shown, a mechanism for cleaning excess adhesive from the corner of a photovoltaic module frame includes a sealing unit 1, a cleaning unit 2, and a drying unit 3.

[0019] like Figure 5 As shown, the sealing unit 1 includes a sealing mechanism for sealing the corner of the frame of the photovoltaic panel 5. The sealing mechanism is configured to be able to fit into or detach from the corner of the frame of the photovoltaic panel 5. After the sealing mechanism fits into the end face of the corner of the frame of the photovoltaic panel 5, it can form a closed cleaning cavity on the outside of the frame of the photovoltaic panel 5. After the sealing mechanism detaches from the end face of the corner of the frame of the photovoltaic panel 5, the photovoltaic panel 5 can move into or out of the cleaning cavity.

[0020] In this embodiment, the sealing mechanism is divided into four groups, including an upper sealing assembly 11 that seals the frame of the photovoltaic panel 5 from above, a lower sealing assembly 12 that seals the frame of the photovoltaic panel 5 from below, and two sets of side sealing assemblies 13 that seal the adjacent sides of the frame of the photovoltaic panel 5. The four sealing mechanisms seal the corners of the frame of the photovoltaic panel 5 from above, below, and adjacent sides of the frame, respectively.

[0021] The upper sealing assembly 11 includes a first driving mechanism 111, the output end of which drives downward and is connected to an upper sealing plate 112, and a first flexible sealing layer 113 is fixedly connected below the upper sealing plate 112; the lower sealing assembly 12 includes a second driving mechanism 121, the output end of which drives upward and is connected to a lower sealing plate 122, and a second flexible sealing layer 123 is fixedly connected above the lower sealing plate 122; the side sealing assembly 13 includes a third driving mechanism 131, which drives towards the frame of the photovoltaic panel 5 and is connected to a side sealing plate 132.

[0022] The first flexible sealing layer 113 and the second flexible sealing layer 123 can be made of elastomer materials such as urethane or polyurethane to provide compression cushioning, thereby sealing tightly while protecting the photovoltaic panel 5. Similarly, a flexible sealing layer (not shown in the figure) can also be provided on the side of the side sealing plate 132 near the frame of the photovoltaic panel 5. The four drive mechanisms (first drive mechanism 111, second drive mechanism 121 and two third drive mechanisms 131) can be cylinders, hydraulic cylinders or other linear drive elements.

[0023] Once the photovoltaic panel 5 is transported to the designated workstation, the four drive mechanisms start synchronously or sequentially, driving their respective sealing plates to press against the frame of the photovoltaic panel 5 from four directions (up, down, left, and right). The flexible sealing layer undergoes elastic deformation under pressure, tightly adhering to the surface of the photovoltaic panel 5, thus collectively forming a cleaning chamber isolated from the outside environment. The four sealing plates of the four drive mechanisms are respectively pressed against the frame surface of the photovoltaic panel 5. The movement trajectory and effective range of each sealing plate are limited to its corresponding frame plane, and there is no need for extension or overlap at the corners of the photovoltaic panel 5's frame, thereby avoiding mechanical interference between adjacent sealing plates.

[0024] like Figures 3 to 4 As shown, the cleaning unit 2 is located inside the cleaning chamber and includes two sets of high-pressure water jet rinsing mechanisms located on both sides of the adjacent frame of the photovoltaic panel 5. The two sets of rinsing mechanisms are configured to move synchronously towards or away from each other and spray high-pressure water jets to rinse the colloid on the corner of the frame of the photovoltaic panel 5.

[0025] The cleaning unit 2 includes a fourth drive mechanism 21, which includes a drive device 211 and a transmission mechanism 212. A first mounting base 23 and a second mounting base 24 are fixedly connected to the transmission mechanism 212. Both the first mounting base 23 and the second mounting base 24 support a nozzle 25.

[0026] The two rinsing mechanisms include a first rinsing mechanism and a second rinsing mechanism. The first rinsing mechanism is a combination of a first mounting base 23 carrying a nozzle 25, and the second rinsing mechanism is a combination of a second mounting base 24 carrying a nozzle 25. The driving device 211 drives the conveying mechanism 212 to drive the first rinsing mechanism and the second rinsing mechanism to spray water in the cleaning chamber to rinse the colloid on the corner of the frame of the photovoltaic panel 5.

[0027] A preferred embodiment is as follows: Each set of rinsing nozzles 25 can be arranged in two groups, one vertically and one vertically, on the photovoltaic panel 5. Each nozzle is deflected at a certain angle towards the photovoltaic panel 5 to ensure that the high-pressure water jets form mutually impacting "water jets" that circulate back and forth. This allows the high-pressure water jets from both sides to converge and impact at the corners of the photovoltaic panel 5's frame, creating a more effective cleaning force and thoroughly rinsing the excess adhesive from the corners of the photovoltaic panel 5's frame. It should be noted that the number, layout, and angle of the nozzles 25 can be adjusted according to the actual cleaning effect.

[0028] The conveying mechanism 212 includes a drive wheel 221, a driven wheel group, and a conveyor belt 226 connected to the output end of the drive device 211. The first mounting base 23 and the second mounting base 24 are fixedly connected to the conveyor belt 226 and are configured to drive the first mounting base 23 and the second mounting base 24 to move synchronously towards or away from each other along the right-angle side of the adjacent frame of the photovoltaic panel 5 when the conveyor belt 226 is running.

[0029] In this embodiment, the drive device 211 is a motor. The driven wheel assembly and the drive wheel 221 are arranged in the same horizontal plane, and the driven wheel assembly includes four driven wheels: a first transmission wheel 222, a second transmission wheel 223, a third transmission wheel 224, and a fourth transmission wheel 225. A closed-loop conveyor belt 226 surrounds the drive wheel 221 and all the driven wheels. The positional relationship between the drive wheel 221 and all the driven wheels defines the running path of the conveyor belt 226: the second transmission wheel 223 and the fourth transmission wheel 225 are located at the ends of the rinsing mechanism's moving direction, the first transmission wheel 222 is located at the turning point between the drive wheel 221 and the second transmission wheel 223, and the third transmission wheel 224 is located at the turning point between the second transmission wheel 223 and the fourth transmission wheel 225. The conveyor belt 226 forms a vertical conveyor line between the drive wheel 221 and the fourth conveyor wheel 225. Through the turning and positioning of the first conveyor wheel 222 and the third conveyor wheel 224, the conveyor belt 226 forms a horizontal conveyor line perpendicular to the vertical conveyor line in the direction of the second conveyor wheel 223.

[0030] The first mounting base 23 and the second mounting base 24 are located on the vertical and horizontal conveyor lines, respectively. When one mounting base is located between the first conveyor wheel 222 and the second conveyor wheel 223, the other mounting base is located between the third conveyor wheel 224 and the fourth conveyor wheel 225; when one mounting base is located between the second conveyor wheel 223 and the third conveyor wheel 224, the other mounting base is located between the fourth conveyor wheel 225 and the drive wheel 221. Furthermore, the horizontal straight-line distance of the first mounting base 23 relative to the turning point (e.g., the third conveyor wheel 224) is equal to the vertical straight-line distance of the second mounting base 24 relative to the turning point. This ensures that when the conveyor belt 226 rotates in one direction, the two mounting bases move synchronously towards each other (closer to the corner); when the conveyor belt 226 rotates in the opposite direction, the two mounting bases move synchronously away from each other (away from the corner), thus achieving synchronous rinsing of the excess adhesive from the corners of the photovoltaic panel 5 frame.

[0031] It should be noted that the path implemented using a four-wheel structure in this embodiment is only a preferred solution. In other embodiments, six wheels, eight wheels, or even more guide wheels can be used to construct a more complex transmission path, or other linear transmission mechanisms such as gear racks and pinions or lead screw modules can be used. As long as the synchronous opposite and opposite movements of the two sets of rinsing mechanisms can be achieved, they should all be considered equivalent substitutions of the present invention.

[0032] like Figure 6 As shown, the drying unit 3 is located downstream of the cleaning unit 2. It is used to blow away and dry the residual water when the photovoltaic panel 5 is removed after cleaning, so as to avoid water stains affecting the subsequent operation of the photovoltaic panel 5.

[0033] The air drying unit 3 includes a side air blowing mechanism 31 located on the side of the frame of the photovoltaic panel 5, and a bottom air blowing mechanism 32 located below the photovoltaic panel 5.

[0034] The side-blowing mechanism 31 includes a side air blade 311 for drying, which is fixedly mounted on a first mounting bracket 312. The bottom-blowing mechanism 32 includes a bottom air blade 321 for drying, which is fixedly mounted on a second mounting bracket 322. The first mounting bracket 312 and the second mounting bracket 322 are fixedly assembled in this mechanism. The air outlets of the side air blade 311 and the bottom air blade 321 face the side and bottom corners of the frame of the photovoltaic panel 5, respectively.

[0035] After the high-pressure rinsing of the excess adhesive at the corners of the photovoltaic panel 5 frame is completed, the drying unit 3 is activated. High-pressure airflow is ejected through the side air knife 311 and the bottom air knife 321, forming an "air curtain" that powerfully blows away the corners of the photovoltaic panel 5 frame from the side and bottom, thereby peeling off and removing the attached water droplets, so that the photovoltaic panel 5 leaves the cleaning mechanism in a dry state.

[0036] like Figure 7As shown, in addition, a photovoltaic module frame corner adhesive overflow cleaning mechanism also includes a housing 4, in which the sealing unit 1, the cleaning unit 2 and the drying unit 3 are all housed.

[0037] A through-hole 41 is provided at the bottom of the outer casing 4. The cleaning water and the colloid that falls off during cleaning fall through the through-hole 41 and are discharged from the through-hole 41 into the subsequent circulating water treatment system.

[0038] In a preferred embodiment, a sliding track for the first mounting base 23 and the second mounting base 24 can be fixedly provided inside the outer casing 4. The first mounting base 23 and the second mounting base 24 are provided with matching sliders or grooves, so that the first mounting base 23 and the second mounting base 24 slide more smoothly and stably when sliding horizontally.

[0039] The photovoltaic module frame corner overflow cleaning mechanism of the present invention is configured as four groups, corresponding to the four corners of a photovoltaic panel 5 respectively. The four cleaning mechanisms are connected to a common circulating water system. The circulating water system recycles and filters wastewater and provides rinsing water source. The four cleaning mechanisms are configured to be movable relative to the photovoltaic panel 5 to realize clamping and releasing actions on the photovoltaic panel 5.

[0040] Working principle: First, the photovoltaic panel 5 is transported to the cleaning station, and the cleaning mechanism is driven to align the sealing unit 1 with the corner of the photovoltaic panel 5 frame. The sealing unit 1 is activated, and the drive mechanisms of the upper, lower, and side sealing components extend, causing the flexible sealing layer to tightly adhere to the surface of the photovoltaic panel 5, forming a closed cleaning chamber.

[0041] Next, the cleaning unit 2 is started, and the fourth drive mechanism 21 is operated. Through the drive transmission mechanism 212, the two sets of nozzles 25 move synchronously towards each other along the adjacent frame of the photovoltaic panel 5. After approaching the corner, they move synchronously away from each other. This cycle is repeated to spray high-pressure water jets at the corner of the photovoltaic panel 5 frame to remove excess adhesive. The rinsing process lasts for a preset time to ensure that the excess adhesive is completely removed. The wastewater and adhesive debris generated during rinsing are discharged through the through holes 41 of their respective outer shells 4.

[0042] Finally, the sealing assembly of sealing unit 1 retracts, the cleaning mechanism is driven back to its initial position, and simultaneously the drying unit 3 is activated, with the side air blades 311 and the bottom air blades 321 spraying high-speed airflow to dry the corners of the photovoltaic panel 5 frame. Then, the photovoltaic panel 5 is conveyed out of the cleaning station along the conveyor line.

[0043] The above embodiments are merely illustrative of the technical concept and features of the present invention, intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and should not be construed as limiting the scope of protection of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of the present invention is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of the equivalents of the claims are intended to be included within the present invention.
