Description

Technical Field

[0001] This application relates to the field of photovoltaic module manufacturing technology, and in particular to a handling fixture. Background Technology

[0002] During the production of photovoltaic modules, factors such as instability of production equipment and defective incoming materials may lead to defects such as cracked cells, paralleled cells, parallel strings, microcracks, broken cells, poor soldering, over-soldering, and foreign objects. These defective products are usually handled by rework. During rework, the stacked photovoltaic modules are disassembled, and the defective cells or strings are treated according to their defects. Then, the repaired strings are rearranged.

[0003] During the repair process, photovoltaic modules are handled manually. However, this process can lead to glass bending and issues with broken or fragmented EL (electroluminescence) cells in the cell strings. Utility Model Content

[0004] Therefore, it is necessary to provide a handling fixture to prevent the glass from bending and to avoid problems such as broken or fragmented EL grids in the battery string.

[0006] Supporting components, the supporting components being used to support photovoltaic modules; and

[0007] An anti-displacement component is disposed on the support component and is used to act on the cell string of the photovoltaic module to prevent the cell string from displaced.

[0022] 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.

[0023] See Figure 1 This application provides a handling fixture in one embodiment for handling photovoltaic modules 30. For example, during the production process of photovoltaic modules 30, operators can use the handling fixture to handle photovoltaic stacked modules. Here, a photovoltaic stacked module refers to a photovoltaic module 30 that has been stacked, which is then disassembled. Based on the defects of the photovoltaic module 30, defective cells or strings are addressed accordingly, and the repaired strings are then rearranged.

[0024] See Figure 1 The handling fixture includes a support component 10 and an anti-displacement component 20. The support component 10 is used to support the photovoltaic module 30. The anti-displacement component 20 is disposed on the support component 10 and is used to act on the battery string to prevent the battery string from shifting.

[0025] During the production of photovoltaic module 30, the photovoltaic module 30 is placed on the supporting component 10, which supports the photovoltaic module 30 and prevents the glass in the photovoltaic module 30 from bending during handling. During handling, the anti-displacement component 20 acts on the cell string, which can reduce problems such as electroluminescence (EL) grid breakage or cell breakage caused by cell string movement.

[0026] In one embodiment, see Figure 1 The supporting component 10 includes a lifting frame 11 and a bracket 12. The bracket 12 is disposed on the lifting frame 11 and is used to support the photovoltaic module 30. Optionally, the bracket 12 is hook-shaped. During transportation, the photovoltaic module 30 is placed on the bracket 12, and the bracket 12 supports the photovoltaic module 30. Then, the operator holds the lifting frame 11 and moves the lifting frame 11 to realize the transfer of the photovoltaic module 30.

[0027] In one embodiment, see Figure 1 The lifting frame 11 includes a first member 111 and a second member 112. Both the first member 111 and the second member 112 extend along a first direction, and are spaced apart along a second direction. The first and second directions intersect. Optionally, the first and second directions are perpendicular. X represents the first direction, and Y represents the second direction.

[0028] Further, see Figure 1 Both the first rod 111 and the second rod 112 are provided with brackets 12. In this way, the brackets 12 on the first rod 111 and the second rod 112 can support the opposite sides of the photovoltaic module 30 and prevent the glass in the photovoltaic module 30 from bending.

[0029] In one embodiment, see Figure 1 The first member 111 is provided with multiple brackets 12, which are spaced apart along the length of the first member 111; and / or, the second member 112 is provided with multiple brackets 12, which are spaced apart along the length of the second member 112. In this way, the multiple brackets 12 can distribute the load, preventing damage to the brackets 12 due to stress concentration. Simultaneously, the multiple brackets 12 can support the photovoltaic module 30, preventing the glass in the photovoltaic module 30 from bending during transportation.

[0030] In one embodiment, see Figure 1 The lifting frame 11 also includes a third member 113 and a fourth member 114. Both the third member 113 and the fourth member 114 are located between the first member 111 and the second member 112, extending along a second direction and spaced apart along a first direction. One end of the third member 113 is connected to the first member 111, and the other end is connected to the second member 112. One end of the fourth member 114 is connected to the first member 111, and the other end is connected to the second member 112. This arrangement improves the structural strength of the lifting frame 11, making it less prone to deformation under external forces. Simultaneously, it evenly distributes the weight of the photovoltaic module 30 among the first member 111, the second member 112, the third member 113, and the fourth member 114, preventing localized overload.

[0031] It is understandable that the first member 111, the second member 112, the third member 113 and the fourth member 114 are connected to form a frame structure.

[0032] Optionally, at least one of the third member 113 and the fourth member 114 may be provided with a bracket 12. This allows for better support of the photovoltaic module 30. Of course, in other embodiments, the third member 113 and the fourth member 114 may not be provided with a bracket 12.

[0033] In one embodiment, see Figure 1 The first rod 111 and the second rod 112 are provided with gripping parts 1111. Alternatively, the third rod 113 and the fourth rod 114 are provided with gripping parts 1111. In this way, the gripping parts 1111 can provide a gripping position for the operator, making it convenient for the operator to lift the lifting frame 11.

[0034] Of course, in other embodiments, the support assembly 10 also includes a handhold rod that extends in a first direction and is connected to the third rod 113 and the fourth rod 114; or, the handhold rod extends in a second direction and is connected to the first rod 111 and the second rod 112. Thus, the handhold rod provides a gripping position for the operator, facilitating the lifting of the frame 11.

[0035] In one embodiment, see Figure 2 The supporting component 10 also includes a positioning element 13, which is disposed on the bracket 12 and is used to position and cooperate with the photovoltaic glass. During transportation, the photovoltaic module 30 is placed on the bracket 12, and the positioning element 13 can position the photovoltaic glass, thereby fixing the photovoltaic glass, preventing it from shaking during transportation, and improving the stability of the photovoltaic glass.

[0036] In one embodiment, the positioning element 13 includes a suction cup for adsorbing the photovoltaic glass. Optionally, the suction cup is a vacuum suction cup, employing a negative pressure of -20 kPa to -30 kPa to adsorb the photovoltaic glass. After the photovoltaic module 30 is placed on the bracket 12, the suction cup adheres to the photovoltaic glass to position it, preventing it from shaking during handling and improving its stability.

[0037] Optionally, multiple suction cups are provided, and multiple suction cup arrays are arranged. The diameter of the vacuum suction cup is 15mm, and the distance between two adjacent vacuum suction cups is 30mm.

[0038] Furthermore, the surface of the suction cup is coated with a low-friction coefficient film. When the suction cup adsorbs the photovoltaic glass, the film comes into contact with the film layer of the photovoltaic module 30. Due to the low coefficient of friction of the film layer, the friction between the suction cup and the photovoltaic glass is reduced, thereby reducing the scratch rate of the photovoltaic glass.

[0039] Specifically, the coefficient of friction of the film layer is less than 0.1. Optionally, the film layer is a silicone layer or a resin layer.

[0040] In another embodiment, the support assembly 10 further includes a cushioning pad disposed on the bracket 12. During handling, the photovoltaic module 30 is placed on the cushioning pad, which absorbs and disperses impact forces, protecting the photovoltaic module 30 from the effects of collisions and vibrations.

[0041] Optionally, the buffer pad is an air cushion, which provides upward support. The internal pressure deviation of each air cushion is controlled to be less than or equal to 5%, ensuring that the flatness fluctuation of the photovoltaic glass is less than or equal to 0.3 mm / m.

[0042] In one embodiment, see Figure 1 The anti-displacement component 20 includes a magnetic chuck 21. The magnetic chuck 21 is mounted on the lifting frame 11 and is used to magnetically engage with the solder strips of the battery string. Optionally, the magnetic chuck 21 is an electromagnet module with a magnetic field strength of 50mT to 80mT. This prevents the battery string from shifting, thereby avoiding problems such as broken or fragmented EL cells.

[0043] Specifically, at least one of the first rod 111 and the second rod 112 is provided with a magnetic attracting element 21. This arrangement allows the magnetic attracting element 21 on the first rod 111 to magnetically engage with the solder ribbon on the battery cell near the first rod 111, and the magnetic attracting element 21 on the second rod 112 to magnetically engage with the solder ribbon on the battery cell near the second rod 112. This prevents the battery string near the first rod 111 and the second rod 112 from shifting, thereby avoiding problems such as broken or fragmented electroluminescence (EL) cells caused by battery string shifting.

[0044] In one embodiment, see Figure 1 The anti-displacement assembly 20 also includes a detection element 22. The detection element 22 is disposed on the lifting frame 11 and is used to detect the position of the solder strips on the battery string. Specifically, at least one of the third member 113 and the fourth member 114 is provided with the detection element 22. Thus, the magnetic field strength can be adjusted according to the position of the solder strips, for example, by increasing or decreasing the number of magnetic attractors 21.

[0045] Optionally, the detection element 22 is a Hall sensor. In the photovoltaic module 30, the solder ribbon generates a magnetic field when current passes through it. By setting a Hall sensor, the Hall sensor can detect the change in the magnetic field generated by the solder ribbon current, thereby determining the position of the solder ribbon.

[0046] Of course, in other embodiments, the detection element 22 may be an image acquisition element that acquires images of the battery string to determine the position of the solder strip.

[0047] In one embodiment, the anti-displacement component 20 further includes a transmitter. The transmitter is located on the support frame 11 and is capable of emitting a collimated beam along a first direction for calibrating the photovoltaic module. Specifically, at least one of the third member 113 and the fourth member 114 is equipped with a transmitter. Thus, operators can adjust the placement angle of the photovoltaic module 30 according to the collimated beam, ensuring that the support component 10 accurately supports the photovoltaic module 30 and avoiding insufficient support for the photovoltaic module 30 due to tilting.

[0048] Optionally, the transmitter is a laser. Lasers emit long, narrow beams of light, enabling precise positioning. Furthermore, the laser beam is stable, unaffected by environmental factors, and maintains consistent performance over long periods.

[0049] Of course, in other embodiments, the transmitter may also be an LED light source.

[0050] In one embodiment, multiple transmitters are provided, spaced apart along a second direction. The spacing between two adjacent transmitters is equal to the length of the battery string in the second direction, so that a laser corresponds between two adjacent battery strings. This arrangement allows operators to adjust the placement angle of the photovoltaic module 30 based on multiple reference lines, improving the accuracy of photovoltaic module 30 placement.

[0051] In one embodiment, the anti-offset component 20 further includes a measuring element and an alarm. The measuring element measures the offset of the solder strip. The alarm is communicatively connected to the measuring element and is activated when the offset is greater than or equal to a predetermined value. Optionally, the predetermined value is 0.5 mm. This alerts operators to adjust the placement angle of the photovoltaic module 30 in a timely manner.

[0055] 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.
