Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, and in particular to a photovoltaic module production line system. Background Technology

[0002] A photovoltaic (PV) panel is a device that directly converts solar energy into electrical energy. It is a core component of photovoltaic (PV) power generation systems and is widely used in residential, commercial, and industrial solar power systems. The working principle of a PV panel is based on the photovoltaic effect. When sunlight shines on the surface of a PV panel, photon energy is absorbed by the semiconductor material (usually silicon), causing electrons to jump from the valence band to the conduction band, thus generating electron-hole pairs. These electron-hole pairs separate under the influence of an electric field formed inside the semiconductor; electrons are pushed to the negative electrode region of the semiconductor, and holes are pushed to the positive electrode region, thereby generating a voltage across the PV panel. Through an external circuit connection, these free electrons can form a current to power a load.

[0003] Currently, the production and assembly of photovoltaic panels involves multiple manual operations to complete the work at different workstations and in different directions. On the one hand, the repetitive and continuous work places high demands on the operators' physical strength. On the other hand, after the overall assembly of multiple photovoltaic panels, manual operations such as flipping and unloading are still required, resulting in low reliability and low efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this application provides a photovoltaic module unloading system to solve the problems of difficult operation and low efficiency when manually unloading photovoltaic modules as a whole in the existing technology.

[0005] The above-mentioned objectives of this application are mainly achieved through the following technical solutions:

[0007] Operating platform;

[0008] The unloading work frame is set on the work platform and is used to support the assembled photovoltaic modules;

[0009] A down-line assembly is arranged on a work platform for connecting the photovoltaic module to the back surface of the photovoltaic module. The down-line assembly can reciprocate between the two sides of the down-line work frame. Before the photovoltaic module is placed on the down-line work frame, the down-line assembly can move to one side of the down-line work frame and be fixedly connected to the mounting parts on the back surface of the photovoltaic module. After the down-line assembly is fixedly connected to the photovoltaic module, the down-line assembly can drive the photovoltaic module to move out to the other side of the down-line work frame.

[0010] In an optional embodiment, a displacement member is provided between the unloading component and the working platform. The displacement member includes a first support and a first track that are movably connected. The first track is fixedly mounted on the working platform. The first support is provided with a first driving member for driving the first support to reciprocate on the first track.

[0011] In an optional embodiment, the offline assembly includes a connector for connecting the assembly, the connector having a first state of fixedly connecting the assembly and a second state of releasing the assembly.

[0012] In an optional embodiment, the connector includes two clamping portions that can move closer to or further away from each other, and a second driving member connected to each clamping portion. The second driving member drives the clamping portions to move closer to clamp the assembly, or drives the clamping portions to move away to release the assembly.

[0013] In an optional embodiment, the clamping part is provided with a stepped part, and when the clamping part is close to clamping the assembly, the stepped part is fastened to the assembly and restricts the assembly from falling out.

[0014] In an optional embodiment, the offline assembly includes a flipping member for driving the connector to rotate. The flipping member is disposed between the connector and the displacement member. When the connector is fixedly connected to the assembly, the flipping member can drive the connector and the assembly to rotate until the light-receiving surface of the photovoltaic module is arranged facing upwards.

[0015] In an optional embodiment, the flipping component includes a rotatable arc-shaped component and a base, the connecting component is fixedly mounted on the arc-shaped component, and a third driving component is provided between the arc-shaped component and the base, the third driving component being able to drive the arc-shaped component to rotate on the base.

[0016] In an optional embodiment, the arc-shaped component and the base are both arc-shaped, and the arc-shaped component is embedded in the base.

[0017] In an optional embodiment, one of the arc-shaped component and the base is provided with an arc-shaped guide strip, and the other is provided with an arc-shaped guide groove for cooperating with the arc-shaped guide strip. When the arc-shaped component is embedded in the base, the arc-shaped guide strip can reciprocate and extend into the arc-shaped guide groove.

[0018] In an optional embodiment, the unloading rack is provided with a clearance groove to allow the unloading assembly to move back and forth.

[0019] Compared with the prior art, the advantages of this application are:

[0020] The photovoltaic module unloading system described in this application includes a work platform, an unloading frame, and unloading components. The unloading frame is mounted on the work platform and supports the assembled photovoltaic modules. The unloading components are arranged on the work platform for connecting the photovoltaic modules to their back surfaces. The unloading components can reciprocate between the two sides of the unloading frame. Before the photovoltaic modules are placed on the unloading frame, the unloading components can move to one side of the unloading frame and be fixedly connected to the mounting components on the back surface of the photovoltaic modules. After the photovoltaic modules are fixedly connected to the unloading components, the unloading components can move the photovoltaic modules to the other side of the unloading frame. After the photovoltaic modules have completed the connection operation between multiple photovoltaic panels and mounting components, the photovoltaic modules are conveyed to the unloading frame on the work platform. On the assembly line, the photovoltaic modules are kept in their initial positions for the unloading operation, while a relative position is made for subsequent assembly work, maintaining operational efficiency. The unloading modules are pre-moved to one side of the assembly line, i.e., the back side of the photovoltaic module. After the photovoltaic module is on the assembly line, the assembly modules are connected to the components in the photovoltaic module. The displacement and movement of the unloading modules on the work platform move the photovoltaic module to the target position, completing the unloading operation. This replaces manual operations such as flipping and unloading. In repetitive and continuous work cycles, it reduces the intensity of manual labor, improves operational safety, protects the reliability of the light-receiving surface of the photovoltaic module, and improves the reliability and efficiency of the unloading operation.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0027] like Figure 1 As shown, Figure 1 This application provides a schematic diagram of the structure of a photovoltaic module unloading system, which includes a work platform 100, an unloading work rack 200, and unloading modules 300, wherein:

[0028] like Figure 1 As shown, the work platform 100 serves as the positioning base for the off-line system and is located at the subsequent work station of the assembly station. This facilitates the acceptance of the photovoltaic modules that have already been assembled and provides relatively stable connection accuracy for the off-line operation of the photovoltaic modules.

[0029] like Figure 1 As shown, the unloading frame 200 is installed on the work platform 100 to support the assembled photovoltaic modules. The unloading frame 200 is fixed on the work platform 100, and the height of the part of the unloading frame 200 that supports the photovoltaic modules is the same as the height and the same arrangement direction as the conveying system that transports the photovoltaic modules, so that the photovoltaic modules can be moved smoothly and reliably onto the unloading frame 200.

[0030] like Figure 1As shown, the unloading assembly 300 is arranged on the work platform 100 for connecting the photovoltaic module to the back surface of the photovoltaic module. The unloading assembly 300 can reciprocate between the two sides of the unloading work frame 200. Before the photovoltaic module is located on the unloading work frame 200, the unloading assembly 300 can move to one side of the unloading work frame 200 and be fixedly connected to the mounting part 700 on the back surface of the photovoltaic module. After the unloading assembly 300 is fixedly connected to the photovoltaic module, the unloading assembly 300 can drive the photovoltaic module to move out to the other side of the unloading work frame 200.

[0031] It should be noted that after the photovoltaic modules are assembled, a complete assembly 700 is fixedly connected to the back surface of multiple photovoltaic panels. The assembly 700 is used to assemble multiple photovoltaic panels into a whole, and this whole is used as a transportation unit for the finished product assembly and off-line operation.

[0032] After the photovoltaic module is placed on the unloading rack 200, the mounting parts 700 on the back surface of the photovoltaic module can be connected and fixed by the unloading component 300 waiting on one side of the unloading rack 200. The movement of the unloading component 300 will drive the photovoltaic module out of the unloading rack 200 until the photovoltaic module is moved to the target position for subsequent transfer operations.

[0033] In an optional embodiment, the working principle of the photovoltaic module unloading system in this application is as follows: The unloading system includes a work platform 100, an unloading work frame 200, and an unloading assembly 300. The unloading work frame 200 is disposed on the work platform 100 and is used to support the assembled photovoltaic modules. The unloading assembly 300 is arranged on the work platform 100 for connecting the photovoltaic modules from their back surfaces. The unloading assembly 300 can reciprocate between the two sides of the unloading work frame 200. Before the photovoltaic modules are placed on the unloading work frame 200, the unloading assembly 300 can move to one side of the unloading work frame 200 and be fixedly connected to the mounting parts 700 on the back surface of the photovoltaic modules. After the photovoltaic modules are fixedly connected to the unloading assembly 300, the unloading assembly 300 can move the photovoltaic modules to the other side of the unloading work frame 200. When the photovoltaic modules are completed with multiple photovoltaic panels and mounting parts 700... After the connection operation at position 0, the photovoltaic module is transported to the unloading rack 200 on the work platform 100. On the one hand, the photovoltaic module is kept in the initial position for unloading, and on the other hand, it is moved back to make room for subsequent assembly operations, thus maintaining work efficiency. The unloading component 300 is pre-moved to one side of the unloading rack 200, that is, on the back side of the photovoltaic module. After the photovoltaic module is on the unloading rack 200, the assembly parts 700 in the photovoltaic module are connected through the unloading component 300. The displacement of the unloading component 300 on the work platform 100 is used to move the photovoltaic module to the target position, completing the unloading operation of the photovoltaic module. This replaces manual operations such as flipping and unloading. In the repetitive and continuous work cycle, it reduces the intensity of manual labor, improves work safety, protects the reliability of the light-receiving surface of the photovoltaic module, and improves the reliability and efficiency of the unloading operation.

[0034] like Figure 1 , Figure 2 As shown, where Figure 2 The present application provides a structural schematic diagram of the unloading component 300. In an optional embodiment, a displacement member 401 is provided between the unloading component 300 and the work platform 100. The displacement member 401 includes a first support 402 and a first track 403 that are movably connected. The first track 403 is fixedly mounted on the work platform 100. The first support 402 is provided with a first driving member 404 for driving the first support 402 to reciprocate on the first track 403.

[0035] The displacement of the unloading component 300 on the work platform 100 is achieved by the displacement component 401. Specifically, the first track 403 provides guidance for the displacement direction and displacement distance of the unloading component 300, the first support 402 is reciprocally arranged on the first track 403, and the first drive component 404 is connected to and drives the first support 402 to drive the unloading component 300 to complete the displacement.

[0036] like Figure 1 , Figure 2 As shown, in actual arrangement, the first driving component 404 can be a drive motor and a transmission chain, which are connected to the meshing wheel on the first support 402 through the transmission chain to transmit the driving force output by the drive motor and maintain the reciprocating movement of the first support 402 on the first guide rail.

[0037] like Figure 2 , Figure 3 As shown, where Figure 3 A partially enlarged schematic diagram of the connector 501 is provided for an embodiment of this application. In an optional embodiment, the unloading assembly 300 includes a connector 501 for connecting the assembly 700. The connector 501 has a first state of being fixedly connected to the assembly 700 and a second state of releasing the assembly 700.

[0038] The connector 501 is driven to different states to complete the clamping and connection and release and separation actions of the assembly 700. In conjunction with the displacement of the unloading module 300, it can stably grab the photovoltaic module and move it to the target position to complete the unloading.

[0039] like Figure 2 , Figure 3 As shown, in an optional embodiment, the connector 501 includes two clamping portions 502 that can move closer to or further away from each other, and a second driving member 504 connected to the clamping portions 502 respectively. The second driving member 504 drives the clamping portions 502 to move closer to clamp the assembly 700, or drives the clamping portions 502 to move away to release the assembly 700.

[0040] The clamping part 502 can connect to the mounting part 700 on the photovoltaic panel on the back side of the photovoltaic panel to form an overall connection after multiple photovoltaic panels are assembled. This facilitates the overall operation and displacement after multiple photovoltaic panels are assembled, and keeps the connection position away from the main body of the photovoltaic panel to maintain the reliability of the photovoltaic panel. Specifically, when the clamping part 502 connects to the mounting part 700, the first driving member 404 drives the clamping parts 502 to move closer to each other to complete the clamping action, or drives the clamping parts 502 to move away from each other to complete the release action in the target area.

[0041] The second drive unit 504 can be actually configured as a linear drive.

[0042] like Figure 2 , Figure 3 As shown, in an optional embodiment, the clamping part 502 is provided with a stepped part 503. When the clamping part 502 approaches and clamps the assembly 700, the stepped part 503 is fastened to the assembly 700 and restricts the assembly 700 from falling out.

[0043] When the clamping parts 502 come close to each other and clamp the assembly 700, the step part 503 hooks onto the edge of the assembly 700 to prevent the assembly 700 from slipping out between the clamping parts 502, thereby improving the stability of clamping the assembly 700 and reducing the driving force requirement of the second drive member 504.

[0044] like Figure 2 , Figure 3 As shown, in an optional embodiment, the offline assembly 300 includes a flipping member 601 for driving the connector 501 to rotate. The flipping member 601 is disposed between the connector 501 and the displacement member 401. When the connector 501 is fixedly connected to the assembly 700, the flipping member 601 can drive the connector 501 and the assembly 700 to rotate until the light-receiving surface of the photovoltaic module is arranged facing upwards.

[0045] Driven by the flipper 601, the photovoltaic module, together with the connector 501, rotates until the photovoltaic module is rotated to a target state suitable for transportation and stacking. Then, it can be directly transferred or carried out in subsequent operations. The flipper 601 allows the photovoltaic module to be transferred without repositioning, maintaining operational consistency and reliability before and after photovoltaic panel assembly, and improving work efficiency.

[0046] After the photovoltaic modules are arranged with the light-receiving surface facing upwards, multiple photovoltaic panels are supported by the assembly 700, which reduces the shear force at the connection between the photovoltaic panels and the assembly 700 and improves the connection stability between the photovoltaic panels and the assembly 700.

[0047] After the photovoltaic module assembly is connected by connector 501, the connector 501 and the photovoltaic module assembly are rotated by flipping component 601. When the photovoltaic module is flipped so that the light-receiving surface is facing up, connector 501, which forms the back surface of the photovoltaic panel, acts as a support, keeping multiple photovoltaic panels as a whole for transfer and transport. When facing the transfer trolley in the assembly area, the flipped photovoltaic module assembly can be directly transferred without the need for other operating components or manual intervention. This allows for stable offline operation, improves efficiency, effectively avoids applying external loads to the photovoltaic panels during operation, and maintains the reliability of the photovoltaic panels.

[0048] like Figure 2 , Figure 3 As shown, in an optional embodiment, the flipping member 601 includes a rotatably disposed arc-shaped member 602 and a base 603. The connecting member 501 is fixedly disposed on the arc-shaped member 602. A third driving member 604 is provided between the arc-shaped member 602 and the base 603. The third driving member 604 can drive the arc-shaped member 602 to rotate on the base 603.

[0049] The third driving component 604 can be actually configured as a drive motor fixedly connected to the base 603, with a drive gear on the output end of the drive motor and a rack on the arc-shaped component 602 that meshes with the drive gear, so as to realize the rotation drive of the arc-shaped component 602.

[0050] In an optional embodiment, the arc-shaped component 602 and the base 603 are respectively arc-shaped, and the arc-shaped component 602 is embedded in the base 603.

[0051] Conversely, the arc-shaped component 602 rotates relative to the base 603, and the arc-shaped component 602 and the base 603 are respectively arc-shaped. By embedding the arc-shaped component 602 on the base 603, the base 603 always provides uniform support during the relative rotation of the arc-shaped component 602, thereby improving the reliability of dynamic operation.

[0052] In an optional embodiment, one of the arc-shaped component 602 and the base 603 is provided with an arc-shaped guide strip, and the other is provided with an arc-shaped guide groove for cooperating with the arc-shaped guide strip. When the arc-shaped component 602 is embedded in the base 603, the arc-shaped guide strip can reciprocate and extend into the arc-shaped guide groove.

[0053] By matching the arc-shaped guide strip and the arc-shaped guide groove, the offset or separation of the arc-shaped part 602 and the base 603 during relative rotation is avoided, thereby improving the stability of the connection during mutual operation. The arc-shaped guide strip can be arranged on either the arc-shaped part 602 or the base 603, and correspondingly, the arc-shaped guide groove is arranged on the other one of the arc-shaped part 602 and the base 603.

[0054] like Figure 1 As shown, in an optional embodiment, the unloading frame 200 is provided with a clearance groove 201 for the reciprocating movement of the unloading component 300. While keeping the photovoltaic module stably supported, the unloading component 300 is also allowed to move quickly between the two sides of the unloading frame 200 via the clearance groove 201, thus avoiding operational interference.
