Description

Technical Field

[0001] This disclosure relates to the field of photovoltaic module manufacturing equipment technology, and in particular to a photovoltaic module clamping mechanism. Based on this, the disclosure also relates to a photovoltaic module transfer device using the photovoltaic module clamping mechanism. Background Technology

[0002] With the increasing global demand for clean energy, photovoltaic (PV) power generation, as a renewable and pollution-free energy utilization method, has received widespread attention and application. As the core component of a PV power generation system, the production quality and efficiency of PV modules directly impact the development of the entire PV industry. In the PV module production process, the automated framing station is a crucial link, and the performance and stability of its equipment are of great significance for improving production efficiency and product quality.

[0003] In photovoltaic (PV) module manufacturing, based on different module type and process requirements, PV modules can be divided into framed modules and frameless modules. Framed modules, due to their frames, achieve higher strength when multiple PV modules are interconnected. Furthermore, by using oxidation- and corrosion-resistant materials, the frame structure further enhances the strength of each frame mounting point when PV modules are installed together, thereby extending the lifespan of the PV modules. Additionally, the frame provides clamping points for handling PV modules, facilitating manual handling or transportation using machinery.

[0004] Currently, most photovoltaic (PV) module clamping mechanisms on the market use gripping clamps, which hold the PV module by clamping it to both sides. For frameless PV modules, insufficient clamping force can cause the module to fall, while excessive clamping force can damage the PV panel. For framed PV modules, especially those with short bottom edges, using clamps that hold the module to both sides can lead to unstable material handling and wobbling of the PV panel within the frame during transport, also increasing the risk of the entire module falling. This reduces transport efficiency and consequently impacts the efficiency of the PV module production line. Traditional PV module clamping devices suffer from inconvenient transport, unsafe transport processes, and high loss rates, affecting the efficiency and safety of PV module transportation.

[0005] In summary, how to provide a photovoltaic module clamping mechanism that prevents photovoltaic modules from falling off when clamping and transferring them is a technical problem that urgently needs to be solved. Utility Model Content

[0006] One of the technical problems to be solved by this disclosure is: how to provide a photovoltaic module clamping mechanism that is less likely to cause photovoltaic modules to fall off when clamping and transferring photovoltaic modules.

[0007] The first aspect of this disclosure provides a photovoltaic module clamping mechanism, which includes:

[0008] A clamping module, the clamping module including a first clamping member, the first clamping member having a first mating surface and a second mating surface that are perpendicular to each other;

[0009] The driving module includes a first driving member that is throttle connected to a first clamping member to drive the first clamping member to move closer to or further away from the photovoltaic module in a horizontal direction, and to clamp the photovoltaic module by causing a first contact surface and a second contact surface to abut against the bottom surface and side surface of the photovoltaic module, respectively.

[0010] In some embodiments, when the photovoltaic module is clamped, the first clamping member is driven to extend below the frame of the photovoltaic module, the first contact surface is in contact with the lower surface of the frame to support the frame, and the second contact surface is in contact with the side of the frame to clamp the frame.

[0011] In some embodiments, the drive module further includes a second drive member that is drively connected to the first drive member. The second drive member is disposed above the first drive member to drive the first drive member and the clamping module to move in the vertical direction.

[0012] In some embodiments, the clamping module further includes a second clamping member fixedly disposed below the first driving member, the second driving member driving the first driving member to move downward so as to drive the second clamping member to press against the top surface of the photovoltaic module.

[0013] In some embodiments, an elastic member is provided between the first driving member and the second driving member. When the second clamping member is driven to press against the photovoltaic module, the elastic member is compressed so that the second clamping member elastically presses against the photovoltaic module.

[0014] In some embodiments, the drive module further includes a proximity switch fixedly mounted on the first drive member, and the proximity switch signal is connected to the second drive member.

[0015] In some embodiments, the positions of the first and second clamping members for contacting the photovoltaic module are made of soft material to protect the photovoltaic module.

[0016] In some embodiments, the soft material is nylon.

[0017] A second aspect of this disclosure provides a photovoltaic module transfer device, which includes the photovoltaic module clamping mechanism described above.

[0018] In some embodiments, the photovoltaic module transfer device further includes a transfer mechanism capable of moving in any direction on a horizontal plane, the transfer mechanism being connected to the photovoltaic module clamping mechanism to drive the photovoltaic module clamping mechanism to transfer the photovoltaic module.

[0019] Through the above technical solution, the photovoltaic module clamping mechanism provided in this disclosure can prevent photovoltaic modules from falling during the clamping and transfer process. During the use of this photovoltaic module clamping mechanism, the clamping mechanism is moved to a position where the first clamping member is located on both sides of the photovoltaic module. Then, the first driving member drives the first clamping member to move closer to the photovoltaic module until the second contact surface on the first clamping member presses against the side of the photovoltaic module. The first contact surface is located below the bottom of the photovoltaic module. The height of the clamping mechanism is then adjusted so that the bottom of the photovoltaic module is in contact with the first contact surface. At this point, the photovoltaic module can be transferred by moving the clamping mechanism. This clamping mechanism, by setting mutually perpendicular first and second contact surfaces, forms a clamp on the side of the photovoltaic module through the first contact surface while the second contact surface supports the photovoltaic module from the bottom. This ensures that even if the friction provided by the first contact surface is insufficient to firmly clamp the photovoltaic module, the second contact surface can still provide sufficient support force to hold the photovoltaic module in the clamping device, ensuring that the photovoltaic module will not fall out.

[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0033] One of the technical problems to be solved by this disclosure is: how to provide a photovoltaic module clamping mechanism that is less likely to cause photovoltaic modules to fall off when clamping and transferring photovoltaic modules.

[0034] To address the aforementioned technical problems, the first aspect of this disclosure provides a photovoltaic module clamping mechanism, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes:

[0035] Clamping module 1, the clamping module 1 includes a first clamping member 11, the first clamping member 11 having a first contact surface 111 and a second contact surface 112 that are perpendicular to each other;

[0036] The driving module 2 includes a first driving member 21 that is pulsatorically connected to the first clamping member 11 to drive the first clamping member 11 to move closer to or further away from the photovoltaic module in the horizontal direction, and to clamp the photovoltaic module by causing the first contact surface 111 and the second contact surface 112 to abut against the bottom surface and the side surface of the photovoltaic module, respectively.

[0037] Through the above technical solution, the photovoltaic module clamping mechanism provided in this disclosure can prevent the photovoltaic module frame from falling off during the clamping and transfer of the photovoltaic module. During the use of this photovoltaic module clamping mechanism, the clamping mechanism is moved to a position where the first clamping member 11 is located on both sides of the photovoltaic module. Then, the first driving member 21 drives the first clamping member 11 to move closer to the photovoltaic module until the second contact surface 112 on the first clamping member 11 presses against the side of the photovoltaic module. The first contact surface 111 is located below the bottom of the photovoltaic module. The height of the clamping mechanism is then adjusted so that the bottom of the photovoltaic module is in contact with the first contact surface 111. At this point, the photovoltaic module can be transferred by moving the clamping mechanism. This clamping mechanism, by setting mutually perpendicular first contact surfaces 111 and second contact surfaces 112, clamps the photovoltaic module from the side using the first contact surface 111 while supporting the photovoltaic module from the bottom using the second contact surface 112. This ensures that even if the friction provided by the first contact surface 111 is insufficient to firmly clamp the photovoltaic module, the second contact surface 112 can still provide sufficient support force to hold the photovoltaic module in the clamping device, preventing it from falling out. Furthermore, the right angle formed between the mutually perpendicular first contact surface 111 and second contact surface 112 matches the right angles of the four sides of the photovoltaic module, allowing the photovoltaic module to be securely clamped by the first clamping member 11. This prevents the photovoltaic module from shaking and falling out after clamping, making this clamping mechanism safer than existing technologies.

[0038] In some embodiments, the clamping mechanism may have multiple first clamping members 11, which can clamp the photovoltaic module when clamping it. This ensures that the photovoltaic module is supported on its bottom surface by multiple first contact surfaces 111 from different positions, resulting in lower local pressure on the bottom of the photovoltaic module and making it less prone to damage during transfer. Simultaneously, the photovoltaic module is also limited by multiple second contact surfaces 112 from different positions, further reducing the shaking of the photovoltaic module when clamped and transferred by the clamping module 1, thus providing a more stable clamping process.

[0039] In some embodiments, the clamping mechanism may have a plurality of first clamping members 11 corresponding to each side of the photovoltaic module, such that each side of the photovoltaic module has a corresponding first clamping member 11, and thus each side of the photovoltaic module has a corresponding and abutting second contact surface 112. The plurality of first clamping members 11 in the above configuration ensures that each side of the photovoltaic module is limited by the first clamping members 11, thereby ensuring that even if the clamping mechanism is rotated during the transfer process, the photovoltaic module will not be thrown out of the clamping mechanism. This allows the clamping mechanism to safely rotate on a horizontal plane during the transfer process, improving the efficiency of transfer processes that require rotation of the photovoltaic module.

[0040] In some embodiments, such as Figure 3 As shown, when the photovoltaic module is clamped, the first clamping member 11 is driven to extend below the frame of the photovoltaic module. The first contact surface 111 is attached to the lower surface of the frame to support the frame, and the second contact surface 112 is attached to the side of the frame to clamp the frame. When clamping a photovoltaic module with a frame, the first clamping member 11 is driven to move toward the photovoltaic module until the first contact surface 111 is attached to the bottom of the frame in the photovoltaic module, and the second contact surface 112 is attached to the side of the frame in the photovoltaic module. The length of the first contact surface 111 is greater than the width of the bottom edge of the frame, so that when supporting the frame in the photovoltaic module, it has a portion that extends beyond the frame, thereby supporting the photovoltaic panel if the frame of the photovoltaic module falls. In some preferred embodiments, the first bonding surface 111 may be configured to have a groove for accommodating the frame. When it is supported to the bottom of the photovoltaic module, the frame of the photovoltaic module is bonded to the groove, and the remaining part of the first bonding surface 111 is bonded to the photovoltaic panel on the photovoltaic module. This allows the first bonding surface to support both the frame and the photovoltaic panel in the photovoltaic module at the same time, thereby supporting the photovoltaic module more stably and preventing the photovoltaic module from shaking or even falling off during the clamping process.

[0041] In some embodiments, the second contact surface 112 of the first clamping member 11 can be disposed at either end of the first clamping member 11 to clamp the photovoltaic module. The frame of the photovoltaic module is configured to include a portion for fixing the photovoltaic panel and a reinforcing structure located below the portion. A long side protruding from the frame and extending towards the center on a horizontal plane is disposed below the reinforcing structure. When the photovoltaic module is inverted, the long side located on the bottom surface of the photovoltaic module faces upward. The first clamping member 11 of this clamping mechanism can be driven to extend under the long side. By attaching the horizontal first contact surface 111 to the long side of the frame and forming a clamp, an upward support force is provided to the long side of the frame when the clamping mechanism is lifted, thereby maintaining the clamp and moving the photovoltaic module. With the first clamping member 11 configured as described above, this clamping mechanism can clamp the inverted photovoltaic module.

[0042] In some embodiments, such as Figure 1 As shown, the drive module 2 also includes a second drive component 22 that is driveably connected to the first drive component 21. The second drive component 22 is positioned above the first drive component 21 to drive the first drive component 21 and the clamping module 1 to move vertically. During the clamping process, when the clamping mechanism is driven directly above the photovoltaic module to be clamped, the first drive component 21 drives the first clamping component 11 to a position away from the photovoltaic module. The second drive component 22 then drives the first drive component 21 to descend, thereby moving the first clamping component 11 in the clamping module 1 to the clamping position. This allows the first drive component 21 to drive the first clamping component 11 to a position where the first contact surface 111 is in contact with the photovoltaic module and the second contact surface 112 is in contact with the side of the photovoltaic module. When the first clamping component 11 is fully in contact with the photovoltaic module and thus clamps the photovoltaic module, the second drive component 22 drives the first clamping component 11 to rise, thereby moving the photovoltaic module upward so that the photovoltaic module can move along with the clamping mechanism.

[0043] In some embodiments, such as Figure 1 and Figure 3 As shown, the clamping module 1 also includes a second clamping member 12 fixedly disposed below the first driving member 21. The second driving member 22 drives the first driving member 21 to move downward, thereby driving the second clamping member 12 to press against the top surface of the photovoltaic module. The second clamping member 12 is configured to have a bottom surface corresponding to the top surface of the photovoltaic module, so that when driven to move downward and press against the top surface of the photovoltaic module, it can fit against the top surface of the photovoltaic module. Thus, during the process of transferring the photovoltaic module by this clamping mechanism, by applying downward pressure on the photovoltaic module, the photovoltaic module is pressed against the first clamping member 11 to cooperate with the first clamping member 11 and prevent the photovoltaic module from shaking during the transfer process, thus preventing the photovoltaic module from shaking or even falling off. At the same time, since the first clamping member 11 and the second clamping member 12 press against the bottom surface and the top surface of the photovoltaic module respectively, the photovoltaic module is limited in the vertical direction by the clamping module 1. Therefore, this clamping mechanism can be flipped, ensuring that the photovoltaic module will not fall off during the flipping process.

[0044] In some embodiments, such as Figure 1 and Figure 2As shown, an elastic member 221 is provided between the first driving member 21 and the second driving member 22. When the second clamping member 12 is driven to press against the photovoltaic module, the elastic member 221 is compressed, so that the second clamping member 12 elastically presses against the photovoltaic module. After the second driving member 22 drives the first driving member 21 and the second clamping member 12 below the first driving member 21 presses against the photovoltaic module, the second driving member 22 then moves downward, so that the elastic member 221 is subjected to force and compressed, and the elastic member 221 can generate a continuous downward pressure on the first driving member 21, so that the second clamping member 12 can continuously press against the photovoltaic module. The elastic member 221 can absorb the energy of impact or vibration when the clamping mechanism is subjected to impact or vibration, thereby keeping the second clamping member 12 always pressing against the top surface of the photovoltaic module, reducing the collision between the second clamping member 12 and the top surface of the photovoltaic module during impact or vibration, and preventing damage to the top surface of the photovoltaic module.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the drive module 2 also includes a proximity switch 23 fixedly mounted on the first drive member 21, and the proximity switch 23 is signal-connected to the second drive member 22. The proximity switch 23 has a sensor on the same horizontal plane as the first drive member 21, so that when the first drive member 21 is driven by the second drive member 22 to the point where the bottom surface of the first drive member 21 approaches the top surface of the photovoltaic module, the proximity switch 23 can send a signal to the second drive member 22 to slow down its movement until the bottom surface of the first drive member 21 presses against the top surface of the photovoltaic module, at which point the second drive member 22 stops moving. In other embodiments, when a second clamping member 12 is mounted on the bottom of the first drive member 21, the sensor of the proximity switch 23 is on the same horizontal plane as the second clamping member 12, so that when the bottom surface of the second clamping member 12 approaches the top surface of the photovoltaic module, the proximity switch 23 sends an electrical signal to the second drive member 22, so that the second drive member 22 can stop driving the first drive member 21 further downward when the second clamping member 12 just presses against the top surface of the photovoltaic module.

[0046] In some embodiments, when the second clamping member 12 presses against the top surface of the photovoltaic module, the second driving member 22 can be configured to continue driving the first driving member 21 to move downward, so as to compress the elastic member 221 between the first driving member 21 and the second driving member 22, so that the elastic member 221 can provide a continuous downward force to the first driving member 21, and so that the elastic member 221 can still provide downward pressure to the first driving member 21 when the clamping mechanism is subjected to impact or vibration, thereby maintaining the state of the second clamping member 12 pressing against the top surface of the photovoltaic module.

[0047] In some embodiments, the positions of the first clamping member 11 and the second clamping member 12 that are in contact with the photovoltaic module are made of soft material to protect the photovoltaic module. By making the first clamping member 11 and the second clamping member 12 of soft material, all parts of the clamping module 1 that are in contact with the photovoltaic module are made of soft material, thereby avoiding excessive local pressure caused by excessive clamping force during the clamping process, and preventing the photovoltaic module from deforming or even being damaged due to excessive clamping force of each clamping member in the clamping module 1. At the same time, by using soft material to prevent damage to the photovoltaic module by each clamping member in the clamping module 1, the driving members in the driving module 2 can drive each clamping member in the clamping module 1 with stronger force, thereby improving the clamping stability of this clamping mechanism without causing damage to the module due to excessive clamping force.

[0048] In some embodiments, the aforementioned soft material is nylon. Compared to other soft materials, nylon has higher mechanical strength and toughness, better wear resistance, and a mature processing and manufacturing process. By using nylon on each clamping component in the clamping module 1, the cost of using soft materials can be reduced while protecting the photovoltaic module.

[0049] The second embodiment of this disclosure provides a photovoltaic module transfer device, which includes the photovoltaic module clamping mechanism described above.

[0050] In some embodiments, the photovoltaic module transfer device further includes a transfer mechanism capable of moving in any direction on a horizontal plane. The transfer mechanism is connected to the photovoltaic module clamping mechanism to drive the photovoltaic module clamping mechanism to transfer the photovoltaic module. By using the photovoltaic module clamping mechanism described above, when transferring, the photovoltaic module transfer device first moves the clamping mechanism to above the photovoltaic module to be transferred. In the clamping mechanism, the first driving member 21 drives the first clamping member 11 to a position away from the center of the photovoltaic module on the horizontal plane. The second driving member 22 then drives the first driving member 21 to descend until the second clamping member 21 at the bottom of the first driving member 21 presses against the top surface of the photovoltaic module. When the proximity switch 23 sends a signal to the second driving member 22, the first driving member 21 drives the first clamping member 11 to move in a direction close to the photovoltaic module until all parts of the first clamping member 11 are in contact with the photovoltaic module. Then, the second driving member 22 is set to continue to be fixed downward by a certain distance, compressing the elastic member 221 between the second driving member 22 and the first driving member 21 to provide continuous downward pressure. At this time, the clamping mechanism completes the clamping. The transfer mechanism on the photovoltaic module starts operating, transferring the clamping mechanism and the photovoltaic module held in it to a designated position. Once at the designated position, the second driving member 22 in the clamping mechanism moves upward, and the first driving member 21 drives the first clamping member 11 to move away from the photovoltaic module, thereby stopping the clamping of the photovoltaic module and releasing it. At this point, the transfer process ends. By using a photovoltaic module transfer device including the aforementioned photovoltaic module clamping mechanism, the clamping effect when holding the photovoltaic module can be improved, preventing the photovoltaic module from falling during the transfer process.
