[0001] This application belongs to the technical field of photovoltaic module production equipment, specifically relating to a positioning device and a photovoltaic module degumming device. Background Technology

[0002] The production of photovoltaic (PV) modules involves multiple processes, such as frame assembly, lamination, testing, degumming, and packaging. In each process, precise positioning of the PV modules is crucial to ensure smooth production and consistent product quality. For example, in the lamination process, inaccurate positioning can lead to uneven internal structure, affecting the module's power generation efficiency and lifespan. Similarly, in the degumming process, accurate positioning is key to ensuring effective degumming and preventing damage to the modules.

[0003] In the adhesive removal process of photovoltaic module frames, existing positioning methods have the following problems in the adhesive removal scenario: Because the distribution of the adhesive on the frame may be uneven, its viscosity and thickness may also vary, which affects the stability of positioning. For example, when using vacuum adsorption positioning, the adhesive may clog the adsorption pores, reducing the adsorption force and affecting the positioning effect. Summary of the Invention

[0009] Furthermore, the lower clamping mechanism includes a second bracket, a second drive assembly connected to the second bracket, and a lower clamping assembly; The second drive component is used to drive the lower clamping component to move along the first direction, so that the lower clamping component clamps or releases the lower surface of the frame corner.

[0010] Furthermore, the lower clamping assembly includes a second limiting part and a second sealing part, wherein the second limiting part is located on the side of the second sealing part; In the released state, the top surface of the second sealing part is higher than the top surface of the first limiting part; When compressed, the top surface of the second sealing part and the top surface of the first limiting part are at the same horizontal plane.

[0013] Furthermore, the guiding component includes a centering wheel and a fixed shaft, the fixed shaft being perpendicular to the corner of the photovoltaic module's frame, and the centering wheel being rotatable relative to the fixed shaft.

[0014] Embodiments of this application also provide a photovoltaic module adhesive removal device, including the aforementioned positioning device.

[0015] The positioning device in this embodiment uses the guide components of the positioning module to abut against the two sides of the right angle of the photovoltaic module frame, thereby positioning the photovoltaic module. At the same time, the guide components can rotate and roll when abutting the right angle of the frame, so as to adjust the angle and position of the photovoltaic module. Then, through the cooperation of the upper and lower pressing mechanisms, the upper and lower, left and right sides of the frame corner are fixed, thereby achieving the pressing and positioning of the photovoltaic module frame corner.

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0020] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0021] Reference Figures 1 to 20 This application discloses a photovoltaic module adhesive removal device, applied to the cleaning and adhesive removal of the photovoltaic module frame, to achieve automatic cleaning of excess adhesive at the four corners of the photovoltaic module frame, thereby improving adhesive removal efficiency, saving manpower and reducing costs, and ensuring the stability of adhesive removal quality at the corners of the photovoltaic module frame. The disclosed adhesive removal device includes a frame 1, a conveying device 2, and an adhesive removal device.

[0022] Reference Figures 1 to 3 The conveying device 2 is mounted on the frame 1 and is used to transport the framed photovoltaic modules from the previous station to the de-adhesive removal station, and to transport the photovoltaic modules after frame cleaning from the de-adhesive removal station to the next station. Specifically, the conveying device 2 includes a conveyor belt 21, a first motor 22, and a blocking cylinder 23. The first motor 22 is used to control the movement of the conveyor belt 21 to realize the transmission of the photovoltaic modules. The blocking cylinder 23 can extend and retract vertically to position or avoid the photovoltaic modules. When the photovoltaic modules are transported from the previous station to the de-adhesive removal station, the blocking cylinder 23 extends upward to block the photovoltaic modules from continuing to be transported, thereby positioning the photovoltaic modules. When the photovoltaic modules have completed frame cleaning at the de-adhesive removal station, the blocking cylinder 23 retracts downward to avoid the photovoltaic modules, allowing them to be transported to the next station.

[0023] Reference Figure 5The number of adhesive removal devices can be increased or decreased according to the actual usage scenario and needs. Since the photovoltaic module frame to be removed is rectangular in this embodiment, there are four sets of adhesive removal devices in this embodiment, which are respectively set at the four corners of the frame 1 to clean the excess adhesive on the four corners of the photovoltaic module frame. The frame 1 is also provided with a transverse slide rail assembly for driving the adhesive removal device to move laterally along the frame 1 and a longitudinal slide rail assembly for driving the adhesive removal device to move longitudinally along the frame 1. There are two sets of both the transverse slide rail assembly and the longitudinal slide rail assembly, which are arranged opposite to each other. Specifically, the horizontal slide rail assembly includes a first slide rail 101, a first slider 102, a second motor 103, and a first synchronous belt 104. Four sets of adhesive removal devices are disposed on the first slide rail 101. The first slider 102 is disposed at the bottom of the adhesive removal device so that the adhesive removal device is slidably connected to the first slide rail 101. The second motor 103 is used to control the movement of the first slider 102 on the first slide rail 101. By setting the first synchronous belt 104, the adhesive removal device is driven to move synchronously and relatively closer to or away from the photovoltaic module in the horizontal direction. The vertical slide rail assembly includes a second slide rail 1011, a second slider 1012, and a third motor 104. The first slide rail 101 is horizontally mounted on the second slide rail 1011, and the first and second slide rails 1011 are perpendicular to each other. The second slider 1012 is located at the bottom of the first slide rail 101, so that the horizontal slide rail assembly is slidably connected to the second slide rail 1011. The second slider 1012 is controlled to move on the second slide rail 1011 by the third motor 1013, and the second synchronous belt 1014 drives the horizontal slide rail assembly to move synchronously and relatively closer to or away from the photovoltaic module in the longitudinal direction, thereby realizing flexible adjustment of the horizontal and longitudinal positions of the adhesive removal device. In order to ensure smooth transmission of the adhesive removal device during movement, in this embodiment, there are two first slide rails 101 in each set of horizontal slide rail assemblies, and three second slide rails 1011 in each set of longitudinal slide rail assemblies.

[0024] Furthermore, when the photovoltaic module is transported from the previous station to the degumming station, the second motor 103 and the third motor 1013 drive the degumming device to move laterally and / or longitudinally along the frame 1 to avoid the photovoltaic module. After the photovoltaic module is positioned at the degumming station, the second motor 103 and the third motor 1013 drive the degumming device to move laterally and / or longitudinally along the frame 1 and adjust its position relative to the four corners of the photovoltaic module frame to ensure that the degumming device is in the working position.

[0025] Reference Figure 2 and Figure 4Optionally, the adhesive removal device includes a positioning module and an adhesive removal mechanism. Multiple positioning modules are provided, each corresponding to a corner of the photovoltaic module's frame. The number of positioning modules can be increased or decreased according to actual usage scenarios and requirements. Since the photovoltaic module frame is rectangular in this embodiment, four positioning modules are used. Specifically, the positioning module includes an upper pressing mechanism 3, a lower pressing mechanism 4, and a guide component 67. The upper pressing mechanism 3 presses the upper surface of the photovoltaic module frame corner G. The lower pressing mechanism 4 is spaced apart from the upper pressing mechanism 3 and presses the lower surface of the photovoltaic module frame corner G. The guide component 67 is located on both sides of the upper pressing mechanism 3 and the lower pressing mechanism 4 and guides and corrects the photovoltaic module frame corner, fixing it in place at the working position of the adhesive removal mechanism. The adhesive removal mechanism cleans and removes adhesive from the left, right, and bottom surfaces of the photovoltaic module frame corner G, and removes residual water droplets from the photovoltaic module frame, thus achieving automatic adhesive removal from the photovoltaic module frame and improving production efficiency.

[0026] Reference Figure 6 and Figure 7 In some embodiments, the upper pressing mechanism 3 includes a first bracket 31, a first driving assembly 32, and an upper pressing assembly 33. The first driving assembly 32 is mounted on the first bracket 31. Specifically, the first bracket 31 has a vertical plate 310, a horizontal plate 311, and a support shaft 312. The vertical plate 310 is vertically arranged along a first direction, and the horizontal plane of the horizontal plate 311 is perpendicular to the vertical plate 310. The support shaft 312 is connected to the bottom of the horizontal plate 311, so that the bottom of the horizontal plate 311 forms an open space. Further, the first driving assembly 31 is vertically connected to the vertical plate 310, and the driving end of the first driving assembly 31 is connected to the upper pressing assembly 33, for driving the upper pressing assembly 33 to move up and down along the first direction, so that the upper pressing assembly 33 presses or releases the upper surface of the photovoltaic module frame corner G. The first driving assembly 32 can be a cylinder, an electric telescopic rod, or other driving device, which is not specifically limited here.

[0027] Optionally, the upper pressing assembly 33 includes a first limiting part and a first sealing part. There are two first limiting parts, which are located on the left and right sides of the first sealing part, respectively. In the released state of the upper pressing assembly 33, the bottom surface of the first sealing part is higher than the bottom surface of the first limiting part. In the pressed state of the upper pressing assembly 33, both the first sealing part and the first limiting part are in contact with the upper surface of the photovoltaic module frame. The bottom surface of the first sealing part and the bottom surface of the first limiting part are on the same plane to achieve pressing on the upper surface of the photovoltaic module frame corner G and seal the upper surface of the frame corner G. This prevents cleaning fluid from flowing from the gaps into the photovoltaic module due to the lack of sealing in the non-clean area during the degreasing process, thus affecting the product quality of the photovoltaic module.

[0028] Specifically, the first limiting part includes a first limiting plate 331, a first mounting block 332 for mounting the first limiting plate 331, and a first adjusting bolt 333. The first adjusting bolt 333 is connected to the first mounting block 332 to adjust the height of the first limiting plate 331, ensuring that the first limiting part provides appropriate clamping force to the photovoltaic module frame. The first sealing part includes a base plate 334, a first mounting plate 335, and a first adhesive plate 336. To facilitate replacement of the first adhesive plate 336, the top surface of the first adhesive plate 336 is detachably connected to the bottom surface of the first mounting plate 335, and the top surface of the first mounting plate 335 is connected to the bottom surface of the base plate 334. The driving end of the first driving component 32 is connected to the top surface of the base plate 334 to drive the upper pressing component 33 to move up and down, thereby clamping or releasing the photovoltaic module frame corner G. Optionally, the shape of the first adhesive plate 336 can be a strip or a plate with right angles. In this embodiment, the shape of the first adhesive plate 336 is preferably a plate.

[0029] Reference Figure 8 In some embodiments, the lower clamping mechanism 4 includes a second bracket 41, a second drive assembly 42, and a lower clamping assembly 43. The second bracket 41 includes a mounting base 410, a first support plate 411, a second support plate 412, and a guide shaft 413. The mounting base 410, the first support plate 411, and the second support plate 412 are connected sequentially via the guide shaft. Specifically, the mounting base 410 and the second support plate 412 are respectively connected to the two ends of the guide shaft 413. The first support plate 411 passes through the middle of the guide shaft 413. The mounting base 410 and the second support plate 412 are slidably connected to the first support plate 411 via the guide shaft 413. Accommodation spaces are formed between the mounting base 410 and the first support plate 411, and between the first support plate 411 and the second support plate 412.

[0030] The second drive assembly 42 may include a cylinder 420 and a bellows cover 421. The bellows cover 421 is fitted onto the outer surface of the cylinder 420 to prevent water spray from splashing onto the cylinder during degreasing, thus preventing cylinder malfunction or rust and extending the cylinder's service life. The second drive assembly 42 is disposed in the receiving space between the first support plate 411 and the second support plate 412, and its drive end is connected to the bottom surface of the first support plate 411. It is used to drive the lower pressing assembly 43 to move up and down along a first direction, so that the lower pressing assembly 43 presses or releases the lower surface of the photovoltaic module frame corner G. Specifically, when the cylinder 420 extends, the mounting base 410 and the second support plate 412 move downward relative to the first support plate 411; when the cylinder 420 retracts, the mounting base 410 and the second support plate 412 move upward relative to the first support plate 411.

[0031] Optionally, the lower pressing assembly 43 includes a second limiting part and a second sealing part. There are two second limiting parts, which are located on the left and right sides of the second sealing part, respectively. In the released state of the lower pressing assembly 43, the bottom surface of the second sealing part is higher than the bottom surface of the second limiting part. In the pressed state of the lower pressing assembly 43, both the second sealing part and the second limiting part are in contact with the lower surface of the photovoltaic module frame. The bottom surface of the second sealing part and the bottom surface of the second limiting part are on the same plane to achieve pressing of the lower surface of the photovoltaic module frame corner G. At the same time, the lower pressing assembly 43 can seal the non-clean area of ​​the lower surface of the frame corner G, preventing the cleaning liquid from flowing from the gap to the photovoltaic module due to the non-sealed non-clean area during the degreasing work, thus affecting the product quality of the photovoltaic module.

[0032] Specifically, the second limiting part includes a second limiting plate 431, a second mounting block 432 for mounting the second limiting plate 431, and a second adjusting bolt 433. The second adjusting bolt 433 is connected to the second mounting block 432 to adjust the height of the second limiting plate 431, ensuring that the second limiting part provides appropriate clamping force to the photovoltaic module frame. The second sealing part includes a second mounting plate 434 and a second adhesive plate 435. To facilitate replacement of the second adhesive plate 435, the bottom surface of the second adhesive plate 435 is detachably connected to the top surface of the second mounting plate 434, and the bottom surface of the second mounting plate 434 is fixedly connected to the mounting base 410. Optionally, the shape of the second adhesive plate 435 can be a strip or a plate with right angles. In this embodiment, the shape of the second adhesive plate 435 is preferably a strip.

[0033] Reference Figure 9 The positioning device also includes a glue removal mounting plate 61, on which at least two guide components 67 are fixedly mounted. Each guide component 67 includes a centering wheel 671 and a fixed shaft 672. The centering wheel 671 is vertically mounted on the glue removal mounting plate 61 via the fixed shaft 672 and is perpendicular to the corner of the photovoltaic module frame. The centering wheel 671 can rotate relative to the fixed shaft 672 to guide and center the corner G of the frame. Specifically, after the framed photovoltaic modules are conveyed from the previous station to the degumming station via the conveying device 2, the four positioning modules move to the four corners of the photovoltaic module frame for positioning. At this time, the two guide components 67 of each positioning module abut against the two sides of the right angle of the photovoltaic module frame, positioning the photovoltaic module. At the same time, the centering wheel 671 can rotate and roll when abutting the right angle of the frame to adjust the angle and position of the photovoltaic module. Then, through the cooperation of the upper pressing mechanism 3 and the lower pressing mechanism 4, the corners of the frame are fixed both vertically and horizontally, thereby achieving the pressing and positioning of the photovoltaic module frame corners. This effectively prevents the photovoltaic module from shifting or shaking during the degumming process and ensures the stability of the positioning of the photovoltaic module frame corners during degumming.

[0034] Reference Figure 9 and Figure 10 In some embodiments, the adhesive removal mechanism includes a first cleaning mechanism 6 and a second cleaning mechanism 7. The first cleaning mechanism 6 is located on the side of the frame and is used to clean and remove adhesive from the left and right sides of the frame corner G. The second cleaning mechanism 7 is located below the first cleaning mechanism 6 and faces the bottom of the frame corner G, and is used to clean and remove adhesive from the bottom surface of the frame corner G, thereby achieving automatic cleaning of excess adhesive from the photovoltaic module frame. The adhesive removal mounting plate 61 is a rectangular plate with a hollow portion 610 in the middle to accommodate the lower pressing component, the first cleaning mechanism, and the second cleaning mechanism. During the adhesive removal operation, the hollow portion 610 allows the cleaning liquid to flow downwards for collection and utilization, while also preventing water accumulation from affecting the service life of the components.

[0035] The first cleaning mechanism 6 includes a first cleaning component and a first dehumidifying component. The first cleaning component and the first dehumidifying component are mounted side-by-side on the adhesive removal mounting plate 61. During adhesive removal, the first cleaning component sprays high-pressure cleaning fluid to rinse away excess adhesive on the side of the frame corner G, and the first dehumidifying component sprays airflow to blow away residual water droplets on the side of the frame corner G, thereby completing the adhesive removal from the side of the frame corner G. In the embodiments of this application, the first cleaning mechanism has two sets, located on the left and right sides of the frame corner G respectively, both facing the area to be cleaned on the frame corner G.

[0036] In some embodiments, the first cleaning mechanism 6 may include two fourth driving components 64, which are respectively installed at opposite corners of the rectangular adhesive removal mounting plate 61. These components drive the two sets of first cleaning mechanisms 6 to move parallel to each other along a straight line relative to the frame of the photovoltaic module. This allows for expansion or adjustment of the adhesive removal range of the first cleaning and dehumidifying components according to different needs, making the adhesive removal work more flexible and comprehensive. The fourth driving component 64 can be a cylinder, an electric telescopic rod, or other driving device; no specific limitation is made here.

[0037] Optionally, the first cleaning mechanism 6 may further include a mounting member 65 and a first adjusting block 66, wherein the first cleaning component and the first dehumidifying component are mounted side by side on the first adjusting block 66, and the mounting member 65 has a first mounting portion 650, a second mounting portion 651, and a groove portion 652 that is connected between the first mounting portion 650 and the second mounting portion 651 and extends downward, wherein the groove portion 652 is located within the hollow portion 610 of the adhesive removal mounting plate. The second mounting part 651 has an arc-shaped hole, and the top of the first adjusting block 66 is movably connected to the arc-shaped hole of the second mounting part 651. The angle of the first cleaning component and the first dehumidifying component in the horizontal direction can be adjusted by manually rotating the first adjusting block 66, thereby meeting different requirements for the adhesive removal position of the frame. The operation is flexible and convenient. The first mounting part 650 is connected to the driving end of the fourth driving component 64, so that the overall movement of the mounting part 65 can be achieved by driving the first mounting part 650, thereby increasing the adhesive removal range of the first cleaning component and the first dehumidifying component on the side of the frame, avoiding secondary cleaning due to incomplete adhesive removal, and effectively improving the cleaning efficiency and quality of the excess adhesive on the frame of the photovoltaic module.

[0038] Optionally, the first cleaning component may include a first spray head 621. During adhesive removal, the first spray head 621 is used to spray high-pressure cleaning fluid to quickly remove excess adhesive residue from the sides of the frame, thereby improving cleaning efficiency and reducing manual cleaning time. Optionally, the cleaning fluid may be water, detergent, cleaning agent, or other cleaning liquids with cleaning effects; no specific limitation is made here.

[0039] Optionally, the first dehumidification component may include a first jet nozzle 630. When the first spray nozzle 621 is performing cleaning work or after the first spray nozzle 621 has completed cleaning work, the first jet nozzle 630 sprays air through the nozzle to blow off water droplets on the side of the photovoltaic module frame after the first cleaning component has cleaned and removed the adhesive, so as to prevent water droplets from flowing from the gaps in the frame to the photovoltaic module and affecting the product quality of the photovoltaic module.

[0040] Reference Figures 11 to 13 In another embodiment, the first dehumidification component may include a water absorption component 631 and a third support 632. The water absorption component 631 has a water removal state and a water squeezing state. In the water removal state, the water absorption component 631 can absorb water droplets on the frame of the photovoltaic module. In the water squeezing state, the water absorption component 631 can squeeze the water from the water absorption part 6313.

[0041] The water-absorbing component 631 is connected to the adhesive removal mounting plate 61 via the third bracket 632 and is positioned opposite to the frame corner G of the photovoltaic module. Specifically, the third bracket 632 has an upper support plate 6321, a lower support plate 6322, and a second guide shaft 6323. There are at least two second guide shafts 6323, which are located on both sides of the upper support plate 6321 and pass through the upper support plate 6321, and are slidably connected to the upper support plate 6321. The bottom of the second guide shaft 6323 is fixedly connected to the lower support plate 6322, and the top of the second guide shaft 6323 is fixedly connected via a connecting block 6324, so that the third bracket is stably connected to the adhesive removal mounting plate 61.

[0042] Optionally, the water-absorbing assembly 631 may include a fifth drive assembly 6310, a sixth drive assembly 6311, a first linkage mechanism 6312, and a water-absorbing part 6313. The first linkage mechanism 6312 and the water-absorbing part 6313 are in two sets, located on opposite sides of the upper support plate 6321. The fifth drive assembly 6310 is disposed between the upper support plate 6321 and the lower support plate 6322, and is used to drive the water-absorbing part 6313 connected to the upper support plate 6321 to move along a first direction, so that the water-absorbing part 6313 rises or falls. The sixth drive assembly 6310... The drive end of component 11 is connected to the bottom of the upper support plate 6321 and is used to drive the water-absorbing part 6313 to move in the second direction, so that the water-absorbing part 6313 extends or retracts. The first linkage mechanism 6312 is connected between the sixth drive component 6311 and the water-absorbing part 6313 to convert the vertical movement of the sixth drive component 6311 into the lateral movement of the water-absorbing part 6313, thereby realizing the water removal state and the water squeezing state of the water-absorbing component 631. This arrangement reduces the lateral space occupied and makes full use of the longitudinal space, making the structure of the water-absorbing component 631 more compact. Optionally, the water-absorbing part 6313 can be made of a material with water absorption and dehydration properties after squeezing, such as a sponge.

[0043] It should be noted that the first direction and the second direction are perpendicular to each other. For example, the first direction can be up and down, and the second direction can be left and right. The fifth drive assembly 6310 and the sixth drive assembly 6311 can be drive devices such as cylinders or electric telescopic rods, and are not specifically limited here.

[0044] Optionally, the water-absorbing assembly 631 may further include a carrier 6314, a third mounting block 6318, a fourth mounting block 6319, and a connecting shaft 6320, wherein the third mounting block 6318 is fixedly mounted on the upper support plate 6321; the fourth mounting block 6319 is slidably connected to the third mounting block 6318 via the connecting shaft 6320, so that the fourth mounting block 6319 and the third mounting block 6318 are close to or far apart, and the water-absorbing part 6313 is detachably connected to the fourth mounting block 6319.

[0045] Furthermore, the support member 6314 is sleeved on the second guide shaft 6323 and slidably connected to the second guide shaft 6323. The support member 6314 has a first slide groove 6316 on both sides for connecting the input end of the first linkage mechanism 6312. The side of the fourth mounting block 6319 is connected to a second slide groove 6317 for connecting the output end of the first linkage mechanism 6312. The input end of the first linkage mechanism 6312 is connected to a first cam slider 6325, and the output end of the first linkage mechanism 6312 is connected to a second cam slider 6326. The smooth operation of the first linkage mechanism 6312 is achieved through the sliding cooperation of the cam slider in the slide groove.

[0046] Furthermore, the sixth drive assembly 6311 is fixedly connected to the carrier 6314 and its drive end is connected to the upper support plate 6321, so that by driving the sixth drive assembly 6311, the carrier 6314 moves relative to the upper support plate 6321 in the first direction, thereby driving the first linkage mechanism 6312 to move, so that the water absorption part 6313 extends or retracts relative to the frame in the second direction.

[0047] Based on the above settings, in the embodiments of this application, in order to achieve a better dehumidification effect, the initial state of the water absorption component 631 is the water squeezing state. Specifically, the fifth drive component 6310 drives the two sets of water absorption parts 6313 to rise along the first direction to a preset distance, and the sixth drive component 6311 drives the carrier 6314 to continue to rise along the first direction. At this time, the first cam slider 6325 slides outward along the first slide groove 6316, and the second cam slider 6326 slides downward along the second slide groove 6317 to drive the fourth mounting block 6319 to extend along the second direction, so that the two sets of water absorption parts 6313 are squeezed against the inner wall of the waterproof cover 82, thereby realizing the compression and squeezing of the water absorption parts 6313.

[0048] In the dewatering state, the sixth drive assembly 6311 drives the carrier 6314 to descend along the first direction. At this time, the first cam slider 6325 slides inward along the first slide groove 6316, and the second cam slider 6326 slides upward along the second slide groove 6317, so as to drive the fourth mounting block 6319 to retract along the second direction, so as to restore the water-absorbing part 6313 from the water-squeezing state to the natural state. Then, the fifth drive assembly 6310 drives the two sets of water-absorbing parts 6313 to descend along the first direction to a preset distance, and the sixth drive assembly 6311 drives the carrier 6314 to rise along the first direction. Through the movement of the first linkage mechanism 6312, the water-absorbing part 6313 is driven to extend along the second direction, so that the two sets of water-absorbing parts 6313 abut against the two sides of the photovoltaic module frame, realizing the removal of water droplets on the frame. The operation is simple, the dehumidification efficiency is high, and the working efficiency of removing glue from the frame is effectively improved.

[0049] Reference Figure 14The second cleaning mechanism 7 may include a second cleaning component and a second dehumidification component. The second cleaning component and the second dehumidification component are mounted on the bottom of the mounting base 410 via a second connecting plate 76, so that the second cleaning component and the second dehumidification component are located on the bottom surface of the frame corner G.

[0050] Optionally, the second cleaning component may include a second spray head 710. During adhesive removal, the second spray head 710 is used to spray high-pressure cleaning fluid to quickly remove excess adhesive residue from the bottom surface of the frame, thereby improving cleaning efficiency and reducing manual cleaning time. Optionally, the cleaning fluid may be water, detergent, cleaning agent, or other cleaning liquids with cleaning properties; no specific limitation is made here.

[0051] Optionally, the second dehumidification component may include a second jet nozzle 720. When the second spray nozzle 710 is performing cleaning work or after the second spray nozzle 710 has completed cleaning work, the second jet nozzle 720 sprays air through the nozzle to blow off water droplets on the bottom surface of the photovoltaic module frame after the second cleaning component has cleaned and removed the adhesive, so as to prevent water droplets from flowing from the gaps in the frame to the photovoltaic module and affecting the product quality of the photovoltaic module.

[0052] Optionally, the second cleaning mechanism 7 may further include a seventh drive assembly 73, a second linkage mechanism 74, and a second adjusting block 75. The second cleaning assembly and the second dehumidification assembly are connected to the second adjusting block 75. The seventh drive assembly 73 is rotatably vertically connected to the second connecting plate 76 via a rotating shaft 77. The drive end of the seventh drive assembly 73 is connected to the input end of the second linkage mechanism 74, and the output end of the second linkage mechanism 74 passes through the second connecting plate 76 and is connected to the second adjusting block 75, so that the seventh drive assembly 73 drives the second linkage mechanism 74 to rotate the second adjusting block 75.

[0053] Based on this configuration, the working direction of the second cleaning component and the second dehumidification component can be flexibly adjusted, increasing the removal range of the second cleaning component and the second dehumidification component on the bottom surface of the frame. This avoids secondary cleaning due to incomplete removal of adhesive and effectively improves the cleaning efficiency and quality of excess adhesive on the photovoltaic module frame. In addition, due to limited installation space, the cooperation between the vertically arranged seventh drive component 73 and the second linkage mechanism 74 can not only realize the directional adjustment of the second cleaning component and the second dehumidification component, but also effectively save installation space.

[0054] Reference Figure 16 and Figure 17 In some embodiments, the adhesive removal device may further include a sealing assembly 8, which may include an eighth drive assembly 81 and a waterproof cover 82. The eighth drive assembly 81 is mounted on the adhesive removal mounting plate 61, as shown in the figure. Figure 17In the direction of the arrow, the eighth drive assembly 81 is used to drive the waterproof cover 82 to move horizontally parallel to the adhesive removal mounting plate 61. The waterproof cover 82 is set in the hollow part 610 of the adhesive removal mounting plate to cover the adhesive removal mechanism, preventing the cylinder, motor and other parts from rusting or causing other malfunctions due to water spray during adhesive removal, thereby improving the service life of the adhesive removal mechanism parts. In addition, the waterproof cover 82 is also used to seal the non-clean areas on the side of the frame, preventing the cleaning fluid from flowing from the gaps into the photovoltaic module during adhesive removal due to the non-clean areas on the side of the frame not being sealed, thus affecting the product quality of the photovoltaic module.

[0055] Specifically, the waterproof cover 82 is an "L"-shaped cover with three sealed sides and an opening at the bottom. For easy installation, the outer right-angle portion L1 of the waterproof cover 82 has an assembly part 820, which is connected to the drive end of the eighth drive component 81. The inner right-angle portion L2 of the waterproof cover 82 matches the frame corner G of the photovoltaic module, so that when the waterproof cover 82 moves closer to the frame corner G, the inner right-angle portion L2 can come into contact with the frame corner G, thereby sealing the non-clean area of ​​the frame corner G. A right-angle groove L3 is provided at the bottom of the inner right-angle portion L2 to expose the area to be cleaned at the frame corner G. The bottom of the waterproof cover 82 is suspended in the groove 652 of the mounting part 65 and has a certain amount of room to move, so that the waterproof cover 82 can move flexibly under the drive of the eighth drive component 81.

[0056] Optionally, the sealing assembly 8 may also include a third mounting plate 83 and a third adhesive plate 84. There are two third mounting plates 83 and two third adhesive plates 84. The two third mounting plates 83 are respectively disposed above the right-angle groove L3 of the inner right-angle portion L2. In order to facilitate the replacement of the third adhesive plates 84, the two third adhesive plates 84 are detachably connected to the third mounting plate 83, and the two third adhesive plates 84 intersect at the inner right-angle portion L2 to ensure the sealing of the non-clean area of ​​the frame corner G.

[0057] It should be noted that the sealing sheet described in this application can be made of foamed silicone or other elastic, compressible, but non-absorbent materials. The detachable connection method can be adhesive bonding, screw connection, or other detachable connection methods. In the embodiments of this application, it is preferable to connect the mounting plate and the sealing sheet simultaneously with adhesive and bolts to ensure the sealing sheet's firmness and stability during operation.

[0058] Furthermore, the eighth drive component 81 can be a cylinder. When the waterproof cover 82 is in the first position driven by the eighth drive component 81, that is, when the cylinder retracts, the waterproof cover 82 moves away from the left and right sides of the photovoltaic module frame corner G. When the waterproof cover 82 is in the second position driven by the eighth drive component 81, that is, when the cylinder extends, the third adhesive plate 84 of the waterproof cover 82 abuts against the left and right sides of the photovoltaic module frame corner G to seal the non-clean area of ​​the frame corner G.

[0059] Optionally, the sealing assembly 8 may also include an observation window 85, a handle 86, and a second slide rail assembly 87. The observation window 85 is installed on the top of the waterproof cover 82 to allow the operator to view the working status of the adhesive removal mechanism. The handle 86 is installed on the observation window 85 to allow the operator to open the observation window to handle internal malfunctions or other situations of the adhesive removal mechanism. The second slide rail assembly 87 has three sets, including slide rails and sliders. Two sets of the second slide rail assembly 87 are set on the first bracket 31 and connected to both sides of the waterproof cover 82, respectively. The other set of the second slide rail assembly 87 is set on the adhesive removal mounting plate 61 and connected to the assembly part 820. Based on this, the cooperation of the slide rails and sliders can ensure the uniformity and smoothness of the movement speed of the waterproof cover 82, which is conducive to the smooth contact and release of the waterproof cover 82 with the frame corner G, so as to ensure the effective sealing of the non-clean area of ​​the frame corner G.

[0060] Reference Figure 15 In some embodiments, the adhesive removal device may further include an air blowing assembly 44 disposed on the lower pressing mechanism 4. The air blowing assembly 44 has an air blowing port 440. Specifically, the right-angle portion of the second adhesive plate 435 is provided with a groove. The air blowing assembly 44 is disposed between the mounting base 410 and the second adhesive plate 435, and the air blowing port 440 is exposed through the groove of the second adhesive plate 435, so as to form an air curtain to blow away water mist when the adhesive removal mechanism is working, and prevent water mist from adhering to the photovoltaic module and affecting the product quality of the photovoltaic module.

[0061] Furthermore, the air blowing assembly 44 has an air inlet 441, which can be controlled by a solenoid valve to allow gas to enter the gas channel inside the air blowing assembly 44, thereby controlling the gas output of the air outlet 440. When the adhesive removal mechanism starts working, the air blowing assembly 44 can start simultaneously to continuously disperse the water mist until the adhesive removal work is completed.

[0062] In existing technologies, excessive adhesive application during photovoltaic module frame installation can easily lead to severe adhesive overflow. Therefore, in some cases, to prevent this overflow from complicating the removal process and to save costs, operators may reduce the amount of adhesive applied to the frame. However, this can result in the sealant not completely covering the four corners of the frame, significantly reducing its sealing performance and accelerating the oxidation and aging process of the internal materials of the module. Therefore, a pressure-applying mechanism is needed to evenly cover the four corners of the frame with sealant, ensuring complete coverage of all four corners.

[0063] Reference Figure 18 and Figure 19In some embodiments, the adhesive removal device may further include an adhesive pressing mechanism 5 mounted on the lower pressing mechanism 4. The adhesive pressing mechanism 5 includes an adhesive pressing component 51, a third driving component 52, and a first connecting plate 53. The adhesive pressing component 51 and the third driving component 52 are connected via the first connecting plate 53. The third driving component 52 drives the adhesive pressing component 51 to move along a first direction, thereby raising the photovoltaic module relative to the frame. The third driving component 52 may be a motor or other forms, which are not specifically limited here.

[0064] Optionally, the pressing assembly 51 may include a pressure plate 510 and a pressure sensor 511. Specifically, the mounting base 410 has a through hole 4101, and the pressing assembly 51 can move along a first direction in the through hole 4101 driven by the third driving assembly 52. ​​The pressure sensor 511 can be electrically connected to the third driving assembly 52 to control the movement of the third driving assembly 52 by detecting the pressure value. Preferably, in the embodiment of this application, the preset pressure value is 150N. When the pressing assembly 51 is lifted under the drive of the third driving assembly 52, the pressure plate 510 contacts the bottom of the photovoltaic module, so that the photovoltaic module is lifted relative to the frame to a preset distance, thereby allowing the sealing silicone around the frame to flow to completely cover the four corners of the frame, ensuring the sealing performance of the frame after installation.

[0065] Reference Figure 2 and Figure 20 In some embodiments, the adhesive removal device may further include a water collection tank 9, a water tank 10, a filter 11, and a high-pressure water pump 12 connected in sequence by water pipes. Specifically, the water collection tank 9 is used to collect the cleaning liquid flowing down after the adhesive removal mechanism has worked; the water tank 10 is used to store the cleaning liquid and supply the cleaning liquid to the adhesive removal mechanism, and the water tank 10 may be equipped with a liquid level sensor to monitor the water level inside the water tank 10 to prevent overflow or drying out; the filter 11 is used to filter the cleaning liquid supplied to the adhesive removal mechanism to ensure the cleanliness of the cleaning liquid and guarantee the adhesive removal quality; the high-pressure water pump 12 is connected to the adhesive removal mechanism and is used to deliver the cleaning liquid to the adhesive removal mechanism.

[0066] Optionally, the water collection tank 9 is installed on the frame 1 and located at the bottom of the adhesive removal mechanism. The water collection tank 9 may include a tank body 91 and a filter screen mounting plate 92. The bottom surface of the tank body 91 is inclined, and an outlet 910 is provided on the lower side. This arrangement can, on the one hand, buffer the falling water flow through the slope at the bottom of the tank body 91 during the recycling process, reduce water splashing, and keep the equipment and the ground clean. On the other hand, the inclined arrangement allows the water flow to flow directly into the outlet 910 along the slope, and use gravity to accelerate the discharge of the collected cleaning liquid into the water tank 10, avoiding the risks of water accumulation and poor drainage.

[0067] The filter screen mounting plate 92 is used to lay filter materials such as filter paper and filter cloth. It is mounted above the water tank body 91 and has a handle 920 on one side. This allows the filter screen mounting plate 92 to be pulled out via the handle 920 for easy replacement of filter materials or cleaning of the bottom of the water tank body 91. The filter screen mounting plate 92 effectively filters impurities such as glue residue flowing down after the glue removal mechanism has worked, thus enabling the recycling of the cleaning liquid. To ensure rapid and effective recovery of the cleaning liquid, the filter screen mounting plate is preferably a large mesh.

[0068] The working steps of the photovoltaic module adhesive removal equipment in this application embodiment are as follows: S1. The photovoltaic modules are transported to the degumming station using the conveying device 2 to position the photovoltaic modules. S2. Adjust the position of the adhesive removal device relative to the photovoltaic module to ensure that the adhesive removal device is in the working position; S3. Use an adhesive removal mechanism to clean the excess adhesive in the corner G area of ​​the photovoltaic module frame and remove residual water droplets; S4. The adhesive removal device is reset, and the cleaned photovoltaic modules are transported to the next workstation via the conveyor device 2.

[0069] Based on the above steps, the excess adhesive at the four corners of the photovoltaic module frame can be automatically cleaned and removed, thereby overcoming the problems caused by manual adhesive removal, improving production efficiency and quality, and reducing costs.

[0070] In this embodiment of the application, the specific steps for removing adhesive from the four corners of the photovoltaic module frame are as follows: The photovoltaic module is transported to the degumming station by the conveying device 2, and the photovoltaic module is blocked by the blocking cylinder 23 to position the photovoltaic module. The four adhesive removal devices are positioned relative to the four corners of the photovoltaic module frame. The guide component 67 abuts against the two right angles of the photovoltaic module frame to press and position the photovoltaic module, ensuring that the adhesive removal device is in the working position. The upper pressing mechanism 3 is used to press the upper surface of the photovoltaic module frame corner G, the lower pressing mechanism 4 is used to press the lower surface of the photovoltaic module frame corner G, and the sealing component 8 is used to abut against the side of the photovoltaic module frame corner G, so as to isolate and distinguish the area to be cleaned and the non-clean area of ​​the frame corner G, ensure that the non-clean area is sealed, and avoid water seepage in the non-clean area. The first cleaning component and the second cleaning component are used to clean the excess adhesive on the two sides and the bottom of the photovoltaic module frame corner G. The first dehumidification component and the second dehumidification component are used to remove the residual water droplets on the two sides and the bottom of the photovoltaic module frame corner G. The excess adhesive cleaning and water droplet removal can be carried out simultaneously or separately. The adhesive removal process is now complete. The adhesive removal device is reset, and the cleaned photovoltaic modules are transported to the next workstation via conveyor 2.
