Description

Technical Field

[0001] This application relates to the field of solar module manufacturing equipment technology, and in particular to a corner pressing device. Background Technology

[0002] In the current booming development of the solar (photovoltaic) industry, solar modules, as a core component, require crucial control over their production processes and quality. In the related technology's solar (photovoltaic) module production process, the module is mainly composed of materials such as glass, encapsulant film, solar cells, back glass, and backsheet. After lamination in a laminator, a semi-finished module is formed. At this point, encapsulant film overflows from the four edges of the module, requiring a trimming machine to remove this excess film. Next, the module proceeds to the framing process, where a silicone sealant applicator injects silicone into the aluminum frame grooves. Due to its excellent sealing, electrical insulation, and chemical corrosion resistance, the silicone not only firmly bonds and fixes to the glass edges of the semi-finished module but also effectively enhances the module's mechanical properties.

[0003] However, several problems urgently need to be addressed during the framing process. On one hand, to avoid glue overflow from the frame contaminating the equipment and causing dirt on the modules, as well as issues like insufficient glue at the corners, the industry has introduced frame corner pressing and extrusion equipment. While this equipment has successfully solved problems like insufficient glue at the corners and glue overflow contamination to some extent, it has also introduced new issues. Specifically, using this equipment results in excessively large gaps between the glass surfaces at the module corners, leading to unreliable module sealing. This problem can cause a series of serious consequences, such as moisture penetration and corrosion, which can damage the internal structure of the module and reduce its lifespan; electrical safety hazards that may cause circuit failures or even fires; deterioration of mechanical properties that make the module more susceptible to damage under external forces; increased potential-induced degradation (PID) that significantly reduces the module's power generation efficiency; contamination deposition that affects the module's light absorption performance; and system-level impacts that may lead to instability in the entire solar photovoltaic system, ultimately severely affecting product quality.

[0004] While the edge corner extrusion fixture in the relevant technology has solved the problems of uneven glue application and glue overflow pollution caused by uneven glue application in edge glue dispensing equipment, and has also reduced production costs by manually reducing the amount of glue applied by the glue dispensing equipment, the equipment achieves uniform glue application at the corners by lifting the edge and pressing down the glass surface. This operation method inevitably leads to excessive gaps at the corners of the components, resulting in a decrease in the sealing performance of the components. Utility Model Content

[0005] Based on this, a corner pressing device is provided, which can repair the gaps at the corners after pressing, effectively solving the problem of excessive gaps at the corners of solar modules and improving the quality of solar modules.

[0006] A corner-pressing device for a solar panel, the corner-pressing device comprising:

[0007] support;

[0008] The corner pressing mechanism includes a connecting plate and two corner pressing structures. The connecting plate is disposed on the bracket and is movable relative to the bracket along a first direction. The two corner pressing structures are symmetrically disposed on the connecting plate along the first direction and are movable relative to the connecting plate along a second direction. The first direction, the second direction, and the vertical direction are perpendicular to each other.

[0009] And two repair components, each of which includes a push-back drive and a push-back plate. The push-back drive is connected to the corresponding corner pressing structure, and the push-back plate is connected to the push-back drive. The push-back drive is configured to drive the push-back plate to move along the vertical direction, thereby repairing the gaps at the corners of the solar module.

[0010] In one embodiment, the corner pressing device further includes at least one first sliding member, through which the connecting plate is slidably connected to the bracket.

[0011] In one embodiment, the corner pressing structure includes a support frame, a lifting drive unit, and a corner pressing plate. The support frame is slidably connected to the connecting plate, the lifting drive unit is connected to the support frame, and the corner pressing plate is connected to the lifting drive unit. The lifting drive unit is configured to drive the corner pressing plate to move along the vertical direction.

[0012] In one embodiment, the corner pressing device further includes two limiting components connected to the corresponding corner pressing structure, and the limiting components are configured to restrict the movement of the solar panel along the vertical direction.

[0013] In one embodiment, the limiting component includes two limiting members, which are respectively connected to the corner pressing structure, and the two limiting members are respectively located on both sides of the solar panel along the vertical direction.

[0014] In one embodiment, the limiting member includes a limiting drive part and a limiting plate. The limiting drive part is connected to the corner pressing structure, and the limiting plate is connected to the limiting drive part. The limiting drive part is configured to drive the limiting plate to move along the vertical direction.

[0015] In one embodiment, the limiting plates of the two limiting members are of different sizes.

[0016] In one embodiment, the corner pressing device further includes at least a blocking cylinder and a straightening cylinder, the blocking cylinder and the straightening cylinder being connected to the corner pressing structure respectively.

[0017] In one embodiment, the bottom of the bracket is provided with an adjustment foot.

[0018] In one embodiment, the support is made of square steel.

[0019] The aforementioned corner pressing device provides stable support through a bracket. The corner pressing structure within the mechanism allows for flexible corner pressing operations. The repair module corrects the gaps at the corners after pressing, effectively solving the problem of excessive gaps at the corners of solar modules and improving their quality. The push-back drive unit generates a large and stable thrust, ensuring sufficient force to tightly press the glass against the frame when repairing corner gaps. This effectively overcomes friction and other resistance, precisely reducing the gap and guaranteeing a successful repair. Attached Figure Description

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0032] In some exemplary embodiments, such as Figures 1-4 As shown, a corner-pressing device is used to solve problems such as excessive gaps at the corners of solar modules in related technologies, thereby improving the quality of solar modules. The solar module (not shown) includes glass and a frame. The corner-pressing device includes a bracket 1, a corner-pressing mechanism 2, and a repair component 3.

[0033] The support frame 1, as the main support structure of the entire device, is made of square steel, which enhances the overall structural strength of the support frame 1 and ensures greater stability of the entire device. The support frame 1 includes, for example, a support platform 11 and a support frame 12. The support frame 12 can be placed on the ground or at the target location. The support platform 11 is fixedly connected to the support frame 12, and the support platform 11 provides operating space for the corner pressing mechanism 2 and the repair component 3.

[0034] To improve the overall stability of the support frame 1, adjustable feet 13 are provided at the bottom of the support frame 1. The number of adjustable feet 13 is determined according to the actual situation, and can be four, six, or more. Each adjustable foot 13 includes, for example, a support leg 131 and an adjusting screw 132. The support leg 131 is screwed to the support frame 12 via the adjusting screw 132. When the height of the support frame 1 needs to be adjusted to match the height of the production line, simply rotate the adjusting screw 132. Additionally, to facilitate the movement of the support frame 1, the adjustable feet 13 can also be equipped with casters or other structures (not shown in the figure), which can be selected according to actual needs.

[0035] The corner pressing mechanism 2 includes a connecting plate 21 and two corner pressing structures 22. The connecting plate 21 is disposed on the bracket 1 and along the first direction (refer to...). Figure 1 The X-axis shown can move relative to the bracket 1. This movement allows the position of the two corner pressing structures 22 in the first direction to be adjusted, enabling the two corner pressing structures 22 to interact freely and improving the flexibility of operation.

[0036] For example, to achieve a sliding connection between the connecting plate 21 and the bracket 1, the corner pressing device further includes a first sliding member 4, through which the connecting plate 21 is slidably connected to the bracket 1. The first sliding member 4 may include, for example, a first slider 41 and a first slide rail 42. The first slide rail 42 is fixedly mounted on the support platform 11 of the bracket 1, the first slider 41 is fixedly connected to the connecting plate 21, and the first slider 41 is slidably connected to the first slide rail 42. It should be noted that the number of first sliding members 4 can be determined according to actual needs. One can be set and positioned in the middle of the connecting plate 21; or multiple first sliding members 4 can be set at intervals along the second direction to improve overall stability.

[0037] In this embodiment, as Figures 1-4 As shown, two corner-pressing structures 22 are symmetrically arranged on the connecting plate 21 along the first direction, and can also be arranged along the second direction (refer to...). Figure 1 The Y-axis shown can move relative to the connecting plate 21. This movement allows adjustment of the position of the corner pressing structure 22 in the second direction, ensuring that the corner pressing structure 22 corresponds to the corner of the solar module. The first direction, the second direction, and the vertical direction (refer to...) Figure 1 The Z-axis shown are perpendicular to each other.

[0038] In this embodiment, as Figures 1-4 As shown, there are two repair components 3, which are set one-to-one with the corner pressing structure 22. Their function is to assist the corner pressing structure 22 and prevent excessive gaps from appearing at the corners of the solar module.

[0039] For example, each repair component 3 includes a push-back drive unit 31 and a push-back plate 32. The push-back drive unit 31 is connected to the corresponding corner pressing structure 22, and the push-back plate 32 is connected to the push-back drive unit 31. The push-back drive unit 31 is configured to drive the push-back plate 32 to move vertically, thereby repairing the problem of excessive gaps at the corners of the solar module. The push-back drive unit 31 is, for example, a push-back cylinder, which is positioned above the solar module. The drive end of the push-back cylinder drives the push-back plate 32 to move downwards, thereby repairing the gaps at the corners of the solar module.

[0040] The push-back cylinder generates a large and stable thrust, ensuring that the push-back plate 32 has sufficient force to tightly adhere the glass to the frame when repairing gaps at the corners of the solar modules. This effectively overcomes friction and other resistance between the two, thereby precisely reducing the gap and ensuring a successful repair. The controllable stroke of the push-back cylinder allows the movement distance of the push-back plate 32 to be precisely adjusted according to the actual size of the gaps at the corners of the solar modules, avoiding over-compression or insufficient repair.

[0041] The corner pressing device provided in this embodiment provides stable support through bracket 1, enables flexible corner pressing operation through corner pressing mechanism 2, and repair component 3 repairs the corner gap after corner pressing, effectively solving the problem of excessive corner gap of solar module and improving the quality of solar module.

[0042] In some exemplary embodiments, such as Figures 1-4 As shown, the corner pressing structure 22 includes a support frame 221, a lifting drive unit 222, and a corner pressing plate 223. The support frame 221 is slidably connected to the connecting plate 21, providing support and a base for movement for the entire corner pressing structure 22. The lifting drive unit 222 is connected to the support frame 221 and is the power source for driving the corner pressing plate 223. The lifting drive unit 222 is configured to drive the corner pressing plate 223 to move vertically. The corner pressing plate 223 is connected to the lifting drive unit 222 and directly acts on the solar module to realize the corner pressing function.

[0043] The support frame 221 includes, for example, a support plate 2211 and a vertical bracket 2212. The support plate 2211 is slidably connected to the connecting plate 21. For example, the support plate 2211 is slidably connected to the connecting plate 21 via a second sliding member 2213. The second sliding member 2213 includes, for example, a second slide rail 22131 and a second slider 22132. The second slide rail 22131 is fixedly connected to the connecting plate 21, and its connection can be ensured by welding, bolting, or other methods. The second slider 22132 is fixedly connected to the support plate 2211, and can also be fixed using bolts or other connecting members. The second slide rail 22131 and the second slider 22132 are slidably connected. The second slide rail 22131 and the second slider 22132 cooperate with each other to realize the sliding of the support plate 2211 on the connecting plate 21, thereby enabling the entire corner pressing structure 22 to move along the second direction to meet the corner pressing requirements of solar modules at different positions.

[0044] The vertical bracket 2212 is vertically mounted on the support plate 2211, providing support and installation space for the corner structure 22 and the repair component 3. The shape and size of the vertical bracket 2212 can be designed according to the actual installed components and space requirements. For example, a rectangular frame structure can be used to ensure sufficient strength while facilitating the installation and layout of other components.

[0045] The lifting drive unit 222 is connected to the vertical bracket 2212 of the support frame 221, and its function is to drive the corner plate 223 to move vertically. The lifting drive unit 222 can adopt various types of drive devices, such as cylinders, electric push rods, etc. Taking a cylinder as an example, the cylinder body is fixedly installed on the vertical bracket 2212, and the piston rod of the cylinder is connected to the corner plate 223. When compressed air is introduced into the cylinder, the piston rod will extend or retract under the action of air pressure, thereby driving the corner plate 223 to move up and down in the vertical direction. By controlling the air intake and exhaust volume of the cylinder, the movement speed and stroke of the corner plate 223 can be precisely adjusted to meet the corner requirements of solar modules of different specifications.

[0046] The corner plate 223 is made of polyester board, giving it good wear resistance and elasticity, effectively protecting the frame of the solar module and preventing scratches during corner pressing. The corner plate 223 is fixedly connected to the lifting drive unit 222 using a screw connection. Specifically, threaded holes are pre-machined at the connection point between the corner plate 223 and the lifting drive unit 222, and then bolts are used to tightly connect the two together. This connection method facilitates the disassembly and replacement of the corner plate 223. When the corner plate 223 becomes worn or damaged, it can be quickly replaced, ensuring the normal operation of the corner pressing process.

[0047] During long-term use, the screws on the corner plate 223 may loosen. If the corner plate 223 falls off, it may cause serious consequences such as scratches or even breakage of the solar modules during the cornering process. Therefore, the corner plate 223 needs to be inspected regularly to check the tightness of the screws. If any loose screws are found, they should be tightened in time to ensure that the corner plate 223 is firmly connected to the lifting drive unit 222.

[0048] The corner plate 223 is located below the solar module. Driven by the lifting drive unit 222, the corner plate 223 moves upward, contacts the frame of the solar module and applies a certain pressure, thereby supporting and pressing the solar module, ensuring that the corners of the solar module fit tightly, and improving the quality and stability of the module.

[0049] The corner pressing structure 22 provided in this embodiment, through the coordinated action of the support frame 221, the lifting drive part 222 and the corner pressing plate 223, can flexibly and accurately perform corner pressing operations on solar modules. At the same time, its reasonable structure and connection method also ensure the reliability and maintainability of the device.

[0050] In some exemplary embodiments, such as Figures 1-4As shown, the corner pressing device also includes two limiting components 5, which can effectively restrict the movement of the solar module in the vertical direction, ensure the stability and accuracy of the corner pressing process, and thus improve the quality of the solar module. The limiting components 5 correspond one-to-one with the corner pressing structure 22, and are connected to the vertical support 2212 of the corner pressing structure 22. The limiting components 5 are configured to restrict the movement of the solar module in the vertical direction.

[0051] The corner pressing structure 22 is used to press the solar module at the corner, while the limiting component 5 works in conjunction with the corner pressing structure 22 to limit the solar module in the vertical direction and prevent it from moving unnecessarily during the corner pressing process.

[0052] In this embodiment, as Figures 1-4 As shown, the limiting component 5 includes two limiting members 51, which are respectively connected to the corner pressing structure 22. In terms of spatial layout, the two limiting members 51 are positioned on both sides of the solar module along the vertical direction, forming a vertically coordinated limiting mode. Specifically, one limiting member 51 is located below the solar module, serving as support and initial limiting; the other limiting member 51 is located above the solar module, serving as pressing and further limiting. Through this vertically coordinated limiting method, the vertical displacement of the solar module can be controlled in all directions, providing a stable workpiece state for the corner pressing operation.

[0053] In this embodiment, as Figures 1-4 As shown, the limiting member 51 includes a limiting drive unit 511 and a limiting plate 512. The limiting drive unit 511 uses a cylinder as a power source. The cylinder has the advantages of simple structure, stable power output and fast response speed.

[0054] The limit drive unit 511 is connected to the vertical bracket 2212 of the corner pressing structure 22. The limit drive unit 511 can be fixedly installed on the vertical bracket 2212 of the corner pressing structure 22 by bolt connection.

[0055] The limiting plate 512 is connected to the limiting drive unit 511, which is configured to drive the limiting plate 512 to move vertically. The limiting plate 512 is in direct contact with the solar module, and its shape and size can be customized according to the appearance and size of the solar module. For example, the limiting plate 512 can be a triangular plate that fits against the corner of the solar module.

[0056] The limiting plates 512 of the two limiting members 51 are of different sizes. For example, the limiting plates 512 of the two limiting members 51 are different in size. The limiting plate 512 of the upper limiting member 51 has a larger area, which can provide a stable pressing surface for the solar module. Its material can be polyester board, which has good wear resistance and elasticity, and can effectively protect the frame of the solar module during the limiting process and avoid scratches. The surface of the limiting member 51 is finely processed to ensure flatness and good fit with the bottom of the solar module. The limiting plate 512 of the lower limiting member 51 is relatively smaller, but it needs to be precisely designed according to the area on the lower surface of the solar module that needs to be supported, so as to effectively support the solar module.

[0057] The limiting plate 512 is connected to the piston rod of the limiting drive unit 511 by bolts. During connection, it is necessary to ensure that the installation position of the limiting plate 512 is accurate and perpendicular to the axis of the piston rod, so as to ensure that the limiting plate 512 can move smoothly in the vertical direction when the piston rod moves, without any tilting or shaking.

[0058] When the solar panel is placed into the corner clamping device, it first rests on the limiting plate 512 of the lower limiting member 51. At this time, the cylinder of the limiting drive unit 511 is in its initial state, and the piston rod extends, positioning the limiting plate 512 at a suitable height to provide stable support for the solar panel. The lower limiting plate 512 prevents the solar panel from moving excessively downwards or tilting under its own weight, and also serves as a positioning reference to help the operator accurately place the solar panel in the predetermined position.

[0059] After the solar module is initially positioned on the lower limiting member 51, the limiting drive part 511 of the upper limiting member 51 is activated. The piston rod of the cylinder extends, driving the limiting plate 512 downward until the limiting plate 512 is in close contact with the upper surface of the solar module. At this time, the upper limiting plate 512 applies a downward pressure to the solar module, which balances the supporting force of the lower limiting member 51, firmly restricting the solar module to a specific position in the vertical direction. When the cornering structure 22 performs the cornering operation on the solar module, the pressing action of the upper limiting member 51 can effectively prevent the solar module from tilting upward or shifting due to the pressure of the cornering plate 223, ensuring the accuracy and consistency of the cornering operation.

[0060] In this embodiment, the limiting component 5 uses two limiting plates 512 of different sizes to cooperate with the limiting members 51, and the limiting drive part 511 drives the limiting plate 512 to move, thereby realizing the effective limiting of the solar module in the vertical direction, which provides an important guarantee for the high-quality production of the corner pressing device.

[0061] In some exemplary embodiments, such as Figures 1-4As shown, the corner-pressing device also includes at least a blocking cylinder (not shown) and a straightening cylinder (not shown), which are connected to the corner-pressing structure 22. In terms of spatial layout, they are rationally arranged according to the transport path of the solar modules and the position of the corner-pressing operation. The blocking cylinder is positioned at a critical location before the solar modules are transported to the corner-pressing station to intercept them; the straightening cylinder is positioned near the corner-pressing station to fine-tune the position of the solar modules that have already reached the corner-pressing station.

[0062] In this embodiment, the corner pressing device, by setting up a blocking cylinder and a straightening cylinder, and working in conjunction with the corner pressing structure 22, achieves precise limitation of the movement of the solar module and accurate position correction, providing a strong guarantee for high-quality corner pressing operation and improving the production efficiency and product quality of the solar module.

[0063] The corner pressing device disclosed herein includes a bracket 1, a corner pressing mechanism 2, a repair component 3, a first sliding component 4, and a limiting component 5. The bracket 1 is made of square steel, which has advantages such as high strength, good toughness, and impact resistance. Compared to aluminum materials used in related technologies, the square steel bracket 1 can withstand greater pressure and torque, providing stable support for the entire corner pressing device, effectively improving the overall strength of the bracket 1, and ensuring that the various components of the device maintain stable relative positions under long-term use and complex working conditions, reducing problems such as decreased corner pressing accuracy caused by deformation of the bracket 1.

[0064] The corner pressing mechanism 2 presses down the corners of the solar module. The corner pressing mechanism 2 includes two corner pressing structures 22, which are connected together by a connecting plate 21. The connecting plate 21 transmits power and coordinates movement, allowing the two corner pressing structures 22 to operate as a single unit. Furthermore, the two corner pressing structures 22 can move freely along a first direction, giving them the ability to interact freely and flexibly adjust their position according to the size and shape of the solar module, improving operational flexibility and thus enabling more efficient corner pressing of the solar module.

[0065] Each corner structure 22 is equipped with a lifting drive unit 222, which is connected to the connecting plate 21. The main function of the lifting drive unit 222 is to solve the problem of insufficient adhesive in the solar module frame. In actual production, the solar module frame may experience insufficient adhesive, which will affect the integrity and sealing of the frame, thereby reducing the quality and service life of the module. When the detection device detects insufficient adhesive in the solar module frame, it sends a signal to the lifting drive unit 222. The lifting drive unit 222 immediately starts and performs corresponding processing on the frame through specific mechanical actions, such as applying a certain pressure to fill the missing adhesive area with the frame material, ensuring the integrity and sealing of the frame, and preventing problems such as adhesive leakage and water ingress during subsequent use.

[0066] The function of the repair component 3 is to effectively prevent slight deformation of the frame caused by the corner pressing mechanism 2, repair the gap between the glass and the frame, and make the gap between the glass and the frame less than the industry-specified quality standard "≤0.5mm", thereby improving the sealing performance and quality of the solar module.

[0067] The limiting component 5 includes two limiting members 51, which work in conjunction with the repair component 3 and the corner pressing mechanism 2. During the repair process, when the corner pressing mechanism 2 applies pressure to the frame, it may generate a downward pushing force, causing the frame to deform. The function of the limiting member 51 is to prevent this from happening. It limits the position of the solar module, fixes the position of the solar module, and ensures the stability of the module during the repair process. Specifically, the limiting member 51 can constrain the module from multiple directions, such as vertical and horizontal, so that the solar module will not undergo unnecessary displacement and deformation when subjected to corner pressing force and repair force. This avoids a series of problems caused by excessive glass gaps, such as water vapor penetration and corrosion, electrical safety hazards, mechanical performance degradation, aggravated PID effect, pollution deposition effect, and system-level impact, effectively improving product quality.

[0068] In practical applications, to meet the production needs of solar modules of different specifications, the corner pressing mechanism 2 can be not limited to one, but can also be two. When two corner pressing mechanisms 2 are used, they are symmetrically arranged along the second direction to facilitate pressing of all four corners of the solar module. At this time, the repair component 3, the first sliding component 4, the limiting component 5, etc., will be set in correspondence with the corner pressing mechanism 2. For example, each corner pressing mechanism 2 is equipped with an independent set of repair component 3 and limiting component 5, and the number and layout of the first sliding component 4 will also be adjusted according to the position and movement requirements of the two corner pressing mechanisms 2 to ensure that the entire device can work in coordination and achieve synchronous and precise corner pressing and repair of the four corners of the solar module.

[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
