Description

Technical Field

[0001] This application relates to the technical field of photovoltaic module production equipment, and more specifically, to a film strip carrying device and film strip processing equipment. Background Technology

[0002] In the production process of photovoltaic modules, the installation of reflective strips plays a crucial role in improving light energy utilization. Photovoltaic modules are typically encapsulated by a backsheet, a lower encapsulating film, cell strings, an upper encapsulating film, and a glass plate. Gaps exist between adjacent cells and between adjacent strings, making it difficult for light energy reaching these gaps to be directly absorbed or utilized. To improve light energy utilization, the industry uses reflective strips attached to the backsheet at positions corresponding to the gaps between cells and strings. These strips reflect the light energy hitting these gaps onto the glass plate, and then further reflect it onto the cells, thus fully utilizing the light energy in these gaps.

[0003] One method for laying reflective film strips onto a backing plate involves first preparing the reflective film strips to be laid using a film strip processing device, and then picking up the prepared reflective film strips from the film strip processing device using a conveying device and laying them onto the backing plate. Existing film strip processing devices typically include a film-laying mechanism, a cutting mechanism, and a traction mechanism. The film-laying mechanism includes multiple film-laying heads, each for extending one film strip. The traction mechanism is used to clamp the ends of each film strip from each film-laying head and pull the film strip horizontally, allowing each film strip pulled from the film-laying head to pass through the cutting mechanism. The support platform in the film strip carrying device needs to receive each film strip pulled by the traction mechanism before cutting it. The cutting mechanism cuts the film strip after receiving it on the support platform. To prevent interference between the cutting mechanism and the traction mechanism and the support platform in the film strip carrying device, the cutting mechanism and the traction mechanism need to be located on the outer sides of both ends of the support platform when cutting the film strip. As a result, when the membrane strip is cut and received by the support platform, both ends of the strip extend beyond the edge of the platform and droop downwards due to gravity. When the handling device picks up the membrane strip from the platform, the drooping ends cannot contact the picking end of the handling device, and the ends of the strip remain drooping during handling. These drooping ends are prone to folding and wrinkling during the laying process onto the backsheet, leading to uneven installation and consequently affecting the quality and performance of the photovoltaic module. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a membrane strip carrying device and a membrane strip processing equipment, which adopt the following technical solution:

[0005] In a first aspect, examples of this application provide a membrane strip carrying device, which includes a carrying mechanism and a supporting mechanism, wherein:

[0006] The support mechanism includes n support platforms, which are used to support m membrane strips extending along a first direction, where n≥1 and m≥2;

[0007] Each support platform has a support mechanism at both ends;

[0008] The support mechanism includes a first drive assembly and a receiving assembly. The first drive assembly is driven to the receiving assembly. The first drive assembly is configured to drive the receiving assembly to a support position to support the end of the membrane strip extending from the bearing surface of the bearing platform. The first drive assembly is also configured to drive the receiving assembly to a clearance position to clearance the end of the membrane strip extending from the bearing surface of the bearing platform.

[0009] The membrane strip carrying device provided in this application includes a carrying mechanism and a supporting mechanism. A supporting mechanism is respectively set at both ends of the carrying platform. A first driving component in the supporting mechanism is drivenly connected to the receiving component. After the membrane strip is cut, the first driving component can drive the receiving component to move to the supporting position to support both ends of the membrane strip, preventing the membrane strip ends from sagging downwards due to gravity during subsequent handling. The design of the supporting mechanism effectively ensures the flatness of the membrane strip, avoids wrinkles caused by end sagging, thereby improving the accuracy of membrane strip laying and ensuring the overall quality of the photovoltaic module.

[0010] According to some examples of the first aspect of this application, the receiving component includes m first support bars; the first driving component includes m first driving members that correspond one-to-one with the first support bars;

[0011] The support position and the avoidance position are located on the same horizontal plane, and the first driving member is configured to drive the first support bar to move laterally between the support position and the avoidance position in a one-to-one correspondence.

[0012] When each of the first support bars is in the support position, the support surface of each first support bar is flush with the support surface of the support platform, and each first support bar provides corresponding support to the end of the membrane strip located at the same end of the support platform.

[0013] The above describes the first implementation of the support mechanism, which uses m first support bars to support the ends of m membrane strips one by one. This design ensures that the ends of each membrane strip are precisely supported.

[0014] According to some examples of the first aspect of this application, the receiving component includes a second support bar;

[0015] The support position and the avoidance position are located on the same horizontal plane, and the first drive component is configured to drive the second support bar to move laterally between the support position and the avoidance position along a first direction;

[0016] When the second support bar is in the support position, the support surface of the second support bar is flush with the support surface of the support platform, and the second support bar supports the ends of all membrane strips located at the same end of the support platform.

[0017] The above is the second implementation of the support mechanism, which uses a single second support bar to support the ends of all membrane strips located at the same end of the bearing platform. This design simplifies the complexity of the support mechanism and can reduce the overall maintenance cost of the equipment.

[0018] According to some examples of the first aspect of this application, the receiving component includes a third support bar; the first driving component is configured to drive the third support bar to rise to a supporting position to support the ends of all membrane strips located at the same end of the support platform; when the third support bar is in the supporting position, the supporting surface of the third support bar is flush with the supporting surface of the support platform;

[0019] The first drive component is also configured to drive the third support bar down to the avoidance position for avoidance; the support position is higher than the avoidance position.

[0020] The above is the third implementation of the support mechanism, which achieves support or avoidance of the membrane strip end by raising and lowering the third support bar. The third support bar is raised and lowered by the drive of the first drive component. When the third support bar rises to the support position, it can support the ends of all membrane strips located at the same end of the bearing platform. This design simplifies the complexity of the support mechanism and can reduce the overall maintenance cost of the equipment.

[0021] According to some examples of the first aspect of this application, the receiving component includes m fourth support bars; the first driving component includes m second driving members that correspond one-to-one with the fourth support bars;

[0022] The second driving component is configured to drive the fourth support bar to rise to the support position in a one-to-one correspondence, providing one-to-one support to the ends of the m membrane strips located at the same end of the support platform; when the fourth support bar is in the support position, the support surface of the fourth support bar is flush with the support surface of the support platform.

[0023] The second drive unit is also configured to drive the corresponding fourth support bar down to the avoidance position to avoid an obstacle; the support position is higher than the avoidance position.

[0024] The above is the fourth implementation of the support mechanism, which uses m fourth support bars to support the ends of m membrane strips one by one, so that the ends of each membrane strip are precisely supported. In addition, the m fourth support bars are controlled to rise and fall between the support position and the avoidance position by m second driving members that correspond one-to-one with the fourth support bars, realizing an automated membrane strip support process.

[0025] According to some examples of the first aspect of this application, m adsorption groups are arranged at intervals along the second direction on the bearing surface of the bearing platform, and each adsorption group is used to adsorb one membrane strip in a corresponding manner, with the second direction being perpendicular to the first direction.

[0026] Each adsorption group includes a plurality of adsorption holes spaced apart along a first direction, each adsorption hole being connected to a negative pressure gas source, or...

[0027] Each adsorption group includes multiple suction cups spaced apart along a first direction, and each suction cup is connected to a negative pressure gas source.

[0028] By using m adsorption groups spaced at intervals along the second direction to adsorb m membrane strips one-to-one, potential positional shifts and loosening of the membrane strips during support are avoided, ensuring the stability and flatness of the membrane strips on the support platform. This design not only helps improve the accuracy of membrane strip laying but also prevents a decrease in light energy reflection efficiency due to inaccurate membrane strip positioning. Furthermore, the connection design between the adsorption holes or suction cups and the negative pressure air source enables effective adsorption of the membrane strips supported by the platform.

[0029] According to some examples of the first aspect of this application, the support platform includes a support plate and m support strips spaced apart on the support plate along a second direction, each support strip being provided with an adsorption group;

[0030] Each support bar includes at least two support bar segments that extend along a first direction and are arranged adjacent to each other. In the same support bar, the support bar segments located at the beginning and / or end in the first direction are detachably mounted on the support plate, and the remaining support bar segments are fixedly mounted on the support plate.

[0031] The above technical solution, by configuring the carrier strip to consist of at least two segments and designing the first and / or last segments to be detachable, allows for easy replacement of only the end segments when the length of the membrane strip to be supported changes. This improves the carrier platform's compatibility with membrane strips of different lengths, reduces the need to replace the entire carrier platform, and lowers maintenance and production costs. This design allows for flexible adjustment of the length of the first and / or last segments based on changes in membrane strip length during actual production. Furthermore, when a portion of the carrier segment is damaged, only the damaged portion is replaced, rather than the entire carrier strip, which extends the service life of the carrier platform and improves the equipment's economic efficiency.

[0032] According to some examples of the first aspect of this application, the bearing mechanism includes two bearing platforms, which are arranged side by side at intervals along a first direction;

[0033] A support mechanism is provided between the two support platforms. This support mechanism, located between the two support platforms, is used to simultaneously support or allow the ends of the membrane strips extending from both support platforms to pass; or,

[0034] Two support mechanisms are provided between the two carrier platforms. The two support mechanisms are used to support or avoid the ends of the membrane strips extending from the two carrier platforms, respectively.

[0035] The above-mentioned support mechanism can be two support platforms arranged side-by-side with intervals. By setting two side-by-side support platforms with intervals, two sets of film strips can be processed simultaneously, significantly improving production efficiency. In the production process of photovoltaic modules, the processing of reflective film strips is a continuous multi-step operation. Increasing the number of support platforms can achieve parallel processing, reduce waiting time and equipment idle time, and improve the overall capacity of the production line. In addition, setting only one support mechanism between the two support platforms, using a single support mechanism to simultaneously support or avoid the film strip ends extending from the two support platforms, can effectively simplify the overall structure of the equipment and reduce the manufacturing and maintenance costs of the equipment. The design of a single support mechanism reduces the number of repetitive parts, making the equipment more concise and compact. Of course, the operating energy consumption of a single support mechanism is relatively low, which can reduce the energy consumption of the equipment during operation and improve the energy efficiency ratio of the equipment. Alternatively, two support mechanisms can be set between the two support platforms, with the two support mechanisms used to support or avoid the film strip ends extending from the two support platforms respectively. This design allows each support mechanism to precisely support or avoid the film strip ends on the corresponding support platform according to actual needs.

[0036] According to some examples of the first aspect of this application, the support mechanism further includes a second drive component that is driven to correspond one-to-one with the two support platforms, each second drive component being configured to drive the corresponding support platform to rise and / or move laterally in a first direction.

[0037] The connection between the second drive assembly and the support platform enables the support platform to move. Each second drive assembly can drive the corresponding support platform to rise and fall and / or move laterally along the first direction. This design allows the support platform to move under the membrane strip along the membrane strip pulling direction and receive the membrane strip. This flexible design is suitable for receiving membrane strips of different lengths.

[0038] In a second aspect, an example of this application provides a membrane strip processing apparatus that includes the aforementioned membrane strip carrying device.

[0039] By integrating the improved membrane strip support device into the membrane strip processing equipment, the support platform in the membrane strip support device can support m membrane strips extending along the first direction, and the receiving component in the membrane strip support device can support the end of the membrane strip extending out of the support surface of the support platform, preventing the end of the membrane strip from drooping downward due to gravity, thus ensuring the production efficiency and product quality of photovoltaic modules.

[0040] According to some examples of the second aspect of this application, the film strip processing equipment further includes n film-forming devices corresponding one-to-one with the support platform. Each film-forming device includes a film-feeding mechanism, a cutting mechanism, and a traction mechanism, wherein:

[0041] The film-laying mechanism, the cutting mechanism, and the corresponding support platform are arranged sequentially along the first direction;

[0042] The membrane release mechanism is used to release m membrane strips;

[0043] The traction mechanism is used to grip the ends of each membrane strip from the membrane dispensing mechanism and pull the membrane strips along a first direction;

[0044] The support platform is used to support the membrane strip located between the corresponding traction mechanism and the cutting mechanism;

[0045] The cutting mechanism is used to cut the film strip after it is received on the support platform, with both ends of the film strip extending out of the support platform;

[0046] The support mechanisms at both ends of the support platform are used to avoid the membrane strip when the traction mechanism clamps the membrane strip and the cutting mechanism cuts the membrane strip, and also to support the ends of the membrane strip after the traction mechanism releases the membrane strip and the cutting mechanism cuts the membrane strip.

[0047] The support mechanism of this application avoids interference with the film strip when the traction mechanism clamps it and the cutting mechanism cuts it, and supports the end of the film strip after the traction mechanism releases it and the cutting mechanism cuts it. This design effectively avoids interference between the support mechanism and the traction and cutting mechanisms during film strip processing, ensuring smooth operation and production efficiency. Simultaneously, the flexible avoidance and timely support of the support mechanism prevents sagging at the end of the film strip, improves the flatness of the film strip, and ultimately contributes to improving the performance and quality of the photovoltaic modules.

[0060] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0061] like Figure 1-3 As shown, the membrane strip carrying device in this embodiment includes a carrying mechanism 11 and a supporting mechanism 12, wherein:

[0062] The support mechanism 11 includes n support platforms 111, which are used to support m membrane strips extending along a first direction (e.g., the X direction), where n≥1 and m≥2.

[0063] Each support platform 111 has a support mechanism 12 at both ends;

[0064] The support mechanism 12 includes a first drive assembly 121 and a receiving assembly 122. The first drive assembly 121 is driven to the receiving assembly 122. The first drive assembly 121 is configured to drive the receiving assembly 122 to a support position to support the end of the membrane strip extending from the bearing surface of the bearing platform 111. The first drive assembly 121 is also configured to drive the receiving assembly 122 to a clearance position to clearance the end of the membrane strip extending from the bearing surface of the bearing platform 111.

[0065] Optionally, the working process of the membrane strip carrying device of this application is as follows:

[0066] The support mechanisms 12 at both ends of the support platform 111 move to the support position to support the ends of the membrane strip after the membrane strip is cut;

[0067] The support mechanisms 12 at both ends of the support platform 111 are in a clearance position before or when the membrane strip is cut, so as to avoid the end of the membrane strip extending out of the support surface of the support platform 111.

[0068] The membrane strip support device provided in this application includes a support mechanism 11 and a support mechanism 12. A support mechanism 12 is respectively set at both ends of the support platform 111. A first drive component 121 in the support mechanism 12 is driven to a receiving component 122. After the membrane strip is cut, the first drive component 121 can drive the receiving component 122 to move to the support position to support both ends of the membrane strip, preventing the ends of the membrane strip from drooping downwards due to gravity during subsequent handling. The design of the support mechanism 12 effectively ensures the flatness of the membrane strip, avoids wrinkles caused by end drooping, thereby improving the accuracy of membrane strip laying and ensuring the overall quality of the photovoltaic module.

[0069] Optionally, the first drive assembly 121 is a drive assembly for driving the receiving assembly 122 to move to a support position or a clearance position. The first drive assembly 121 includes, but is not limited to, an electric push rod, a cylinder or a linear motor.

[0070] To fully understand this application, four detailed structures of the support mechanism 12 will be presented in the following description to illustrate the technical solution proposed in this application. The four optional embodiments of the support mechanism 12 are described in detail below:

[0071] 1. A first example embodiment of the support mechanism 12:

[0072] The supporting component 122 includes m first support bars 123, for details please refer to Figure 4 , Figure 4 The receiving component 122 provided at the left end of the support platform 111 consists of m first support bars 123; the first drive component 121 includes m first drive members 1213 corresponding one-to-one with the first support bars 123.

[0073] The support position and the avoidance position are located on the same horizontal plane, and the first driving member 1213 is configured to drive the first support bar 123 to move laterally between the support position and the avoidance position in a one-to-one correspondence.

[0074] When each of the first support bars 123 is in the support position, the support surface of each of the first support bars 123 is flush with the support surface of the support platform 111, and each of the first support bars 123 provides corresponding support to the end of the membrane strip located at the same end of the support platform 111.

[0075] The above describes the first embodiment of the support mechanism 12, which uses m first support bars 123 to support the ends of m membrane strips one by one. This design ensures that the ends of each membrane strip are precisely supported.

[0076] Optionally, the bearing platform 111 is provided with m first clearance grooves corresponding one-to-one with the first support bar 123 at the end near the first support bar 123. When the m first support bars 123 move to the clearance position, each first support bar 123 enters the corresponding first clearance groove. When the m first support bars 123 move to the support position, each first support bar 123 extends out of the corresponding first clearance groove.

[0077] Optionally, the first clearance groove may not be provided at the end of the support platform 111 near the first support bar 123. When the m first support bars 123 move to the clearance position, each first support bar 123 is close to the end of the support platform 111, and the support surface of the m first support bars 123 is flush with the support surface of the support platform 111.

[0078] 2. A second example embodiment of the support mechanism 12:

[0079] The receiving component 122 includes a second support bar (not shown in the figure);

[0080] The support position and the avoidance position are located on the same horizontal plane, and the first drive component 121 is configured to drive the second support bar to move laterally between the support position and the avoidance position along a first direction;

[0081] When the second support bar is in the support position, the support surface of the second support bar is flush with the support surface of the support platform 111, and the second support bar supports the ends of all membrane strips located at the same end of the support platform 111.

[0082] The above is the second embodiment of the support mechanism 12, which uses a single second support bar to support the ends of all membrane strips located at the same end of the bearing platform 111. This design simplifies the complexity of the support mechanism 12 and can reduce the overall maintenance cost of the equipment.

[0083] Optionally, the support platform 111 is provided with a second clearance groove on the side near the second support bar, which is adapted to the second support bar. When the second support bar moves to the clearance position, it enters the second clearance groove, and when the second support bar moves to the support position, it extends out of the second clearance groove.

[0084] Optionally, the end of the support platform 111 near the second support bar may not be provided with a second clearance groove. When the second support bar moves to the clearance position, the end of the second support bar near the support platform 111 is flush with the support surface of the support platform 111.

[0085] 3. A third example embodiment of the support mechanism 12:

[0086] The supporting component 122 includes a third support bar 124, for details please refer to Figure 4 , Figure 4The receiving component 122 provided at the right end of the support platform 111 is a third support bar 124; the first drive component 121 is configured to drive the third support bar 124 to rise to the support position to support the ends of all membrane strips located at the same end of the support platform 111; when the third support bar 124 is in the support position, the support surface of the third support bar 124 is flush with the support surface of the support platform 111.

[0087] The first drive component 121 is also configured to drive the third support bar 124 down to the avoidance position for avoidance; the support position is higher than the avoidance position.

[0088] The above is the third embodiment of the support mechanism 12, which supports or avoids the ends of the membrane strips by raising and lowering the third support bar 124. The third support bar 124 is raised and lowered by the drive of the first drive component 121. When the third support bar 124 rises to the support position, it can support the ends of all membrane strips located at the same end of the support platform 111. This design simplifies the complexity of the support mechanism and can reduce the overall maintenance cost of the equipment.

[0089] Optional, please refer to Figure 5 The first drive assembly 121 includes a mounting bracket 1211, a slide rail 1212, and a third drive component 1215, wherein:

[0090] The slide rail 1212 extends vertically and is mounted on the mounting bracket 1211;

[0091] The third support bar 124 is slidably mounted on the slide rail 1212. The fixed end of the third drive member 1215 is fixedly mounted on the mounting bracket 1211. The drive end of the third drive member 1215 is connected to the third support bar 124. The third drive member 1215 is configured to drive the third support bar 124 to move up and down along the slide rail 1212.

[0092] Optional, please continue reading Figure 5 The third support bar 124 is fixedly connected to a buffer 1241, which can rise and fall together with the third support bar 124;

[0093] A positioning seat 1214 is fixedly installed at a preset height on the mounting bracket 1211. The positioning seat 1214 is located on the moving path of the buffer 1241. The third support bar 124 stops moving after the buffer 1241 hits the positioning seat 1214. When the third support bar 124 stops, it is flush with the support platform 111.

[0094] 4. A fourth example embodiment of the support mechanism 12:

[0095] The receiving component 122 includes m fourth support bars; the first driving component 121 includes m second driving members (not shown in the figure) that correspond one-to-one with the fourth support bars (not shown in the figure);

[0096] The second driving member is configured to drive the fourth support bar to rise to the support position in a one-to-one correspondence, and provide one-to-one support for the ends of the m membrane bars located at the same end of the support platform 111; when the fourth support bar is in the support position, the support surface of the fourth support bar is flush with the support surface of the support platform 111.

[0097] The second drive unit is also configured to drive the corresponding fourth support bar down to the avoidance position to avoid an obstacle; the support position is higher than the avoidance position.

[0098] The above describes the fourth implementation of the support mechanism 12, which uses m fourth support bars to support the ends of m membrane strips one by one, ensuring precise support for the ends of each membrane strip. Furthermore, m second drive units, each corresponding to a fourth support bar, control the raising and lowering of the m fourth support bars between the support and avoidance positions, thus achieving an automated membrane strip support process.

[0099] Although exemplary embodiments have been described above with reference to the accompanying drawings, it should be understood that the above exemplary embodiments are merely illustrative and are not intended to limit the scope of this application. Various changes and modifications can be made therein by those skilled in the art without departing from the scope and spirit of this application. All such changes and modifications are intended to be included within the scope of this application as claimed in the appended claims. Furthermore, in the claims, any of the claimed embodiments can be used in any combination.

[0100] Optionally, the support mechanisms 12 located at both ends of the support platform 111 can be selected arbitrarily from the above four example embodiments of support mechanisms 12, and the structures of the support mechanisms 12 located at both ends of the support platform 111 may be the same or different.

[0101] For example, the support mechanism 12 located at the first end of the support platform 111 can adopt the first example embodiment of the support mechanism 12 described above, and the support mechanism 12 located at the second end of the support platform 111 can adopt the third example embodiment of the support mechanism 12 described above.

[0102] For example, the support mechanism 12 located at the first and second ends of the support platform 111 can simultaneously adopt the first example embodiment of the above support mechanism 12.

[0103] Since there are many types of combinations, they will not be listed one by one here.

[0104] The above scheme allows for the optional structure of the support mechanisms 12 located at both ends of the bearing platform 111, meaning they can be the same or different. The optimal configuration can be made according to the specific production environment and membrane strip processing requirements, thereby improving the overall design rationality and operational convenience of the equipment.

[0105] Optionally, m adsorption groups 112 are arranged at intervals along the second direction (e.g., the Y direction) on the bearing surface of the bearing platform 111. Each adsorption group 112 is used to adsorb one membrane strip in a corresponding manner. The second direction is perpendicular to the first direction.

[0106] Each adsorption group 112 includes a plurality of adsorption holes spaced apart along a first direction, each adsorption hole being connected to a negative pressure gas source, or...

[0107] Each adsorption group 112 includes a plurality of suction cups spaced apart along a first direction, each suction cup being connected to a negative pressure gas source.

[0108] Optionally, the suction cup is an elastic suction cup. In its natural state, the suction cup protrudes from the bearing surface of the bearing platform 111. When the suction cup adsorbs the film strip, it deforms elastically, causing the adsorbed film strip to come close to the bearing surface of the bearing platform 111.

[0109] Optionally, the adsorption holes and / or suction cups on the adsorption group 112 may be provided only at the end of the adsorption group 112; or, adsorption holes and / or suction cups may be arranged at both the end and the middle of the adsorption group 112.

[0110] Optionally, the adsorption holes and / or suction cups near the end of the adsorption group 112 should be arranged more densely than at other locations of the adsorption group 112 to better adsorb the end of the membrane strip.

[0111] By using m adsorption groups 112 spaced apart along the second direction to adsorb m membrane strips one-to-one, potential positional shifts and loosening of the membrane strips during the bearing process are avoided, ensuring the stability and flatness of the membrane strips on the bearing platform 111. This design not only helps improve the accuracy of membrane strip laying but also prevents a decrease in light energy reflection efficiency due to inaccurate membrane strip positioning. Furthermore, the connection design between the adsorption holes or suction cups and the negative pressure air source enables effective adsorption of the membrane strips supported by the bearing platform 111.

[0112] Optionally, the support platform 111 includes a support plate 1111 and m support bars 1112 spaced apart on the support plate 1111 along the second direction, and each support bar 1112 is provided with an adsorption group 112.

[0113] Each support bar 1112 includes at least two support bar segments that extend along a first direction and are arranged adjacent to each other. In the same support bar 1112, the support bar segments located at the first end and / or the last end in the first direction are detachably mounted on the support plate 1111, and the remaining support bar segments are fixedly mounted on the support plate 1111.

[0114] In the above technical solutions, each load-bearing strip 1112 includes at least two load-bearing segments; for example, each load-bearing strip 1112 may include three load-bearing segments, then the first and last two load-bearing segments of the three load-bearing segments are detachably installed on the support plate 1111, and the middle load-bearing segment of the three load-bearing segments is fixedly installed on the support plate 1111.

[0115] By configuring the carrier bar 1112 to include at least two carrier bar segments, and designing the first and / or last carrier bar segments to be detachable, when the length of the membrane strip to be carried changes, only the last carrier bar segment needs to be replaced. This improves the compatibility of the carrier platform 111 with membrane strips of different lengths, reduces the need to replace the entire carrier platform 111, and lowers maintenance and production costs. This design allows for flexible adjustment of the length of the first and / or last carrier bar segments according to changes in membrane strip length during actual production. Furthermore, when a portion of the carrier bar segment is damaged, only the damaged portion is replaced, rather than the entire carrier bar 1112, which extends the service life of the carrier platform 111 to some extent and improves the economic efficiency of the equipment.

[0116] Optional, such as Figure 1 and Figure 2 As shown, the bearing mechanism 11 includes two bearing platforms 111, which are arranged side by side at intervals along the first direction;

[0117] A support mechanism 12 is provided between the two support platforms 111. The support mechanism 12 located between the two support platforms 111 is used to simultaneously support or avoid the ends of the membrane strips extending from the two support platforms 111; or,

[0118] Two support mechanisms 12 are provided between the two support platforms 111. The two support mechanisms 12 are used to support or avoid the ends of the membrane strips extending from the two support platforms 111 respectively.

[0119] By setting two parallel, spaced-apart support platforms 111, two sets of reflective film strips can be processed simultaneously, significantly improving production efficiency and shortening the production cycle. In the production process of photovoltaic modules, the processing of reflective film strips is a continuous, multi-step operation. Increasing the number of support platforms 111 enables parallel processing, reducing waiting time and equipment idle time, and increasing the overall capacity of the production line. Furthermore, by setting only one support mechanism 12 between the two support platforms 111, and using a single support mechanism 12 to simultaneously support or avoid the ends of the film strips extending from both support platforms 111, the overall structure of the equipment can be effectively simplified, reducing manufacturing and maintenance costs. The design of a single support mechanism 12 reduces the number of repetitive parts, making the equipment more concise and compact. Of course, the operating energy consumption of a single support mechanism 12 is relatively low, which can reduce energy consumption during equipment operation and improve the equipment's energy efficiency ratio. Alternatively, two support mechanisms 12 can be provided between the two support platforms 111. The two support mechanisms 12 are used to support or avoid the membrane strip ends extending from the two support platforms 111 respectively. This design allows each support mechanism 12 to precisely support or avoid the membrane strip ends on the corresponding support platform 111 as needed.

[0120] Optionally, the support mechanism 11 further includes a second drive assembly 113 that is driven to be connected to the two support platforms 111 in a one-to-one manner. Each second drive assembly 113 is configured to drive the corresponding support platform 111 to move up and down and / or move laterally in a first direction.

[0121] The connection between the second drive assembly 113 and the support platform 111 enables the support platform 111 to move. Each second drive assembly 113 can drive the corresponding support platform 111 to move up and down and / or move laterally along the first direction. This design allows the support platform 111 to move under the membrane strip along the membrane strip pulling direction and receive the membrane strip. This flexible design is suitable for receiving membrane strips of different lengths.

[0122] Optionally, the support mechanism 12 can be set independently of the support platform 111, or it can be installed on the support platform 111 and move with the support platform 111.

[0123] like Figure 6 As shown, the membrane strip processing equipment in this embodiment includes the aforementioned membrane strip carrying device 1.

[0124] By integrating the improved film strip support device 1 into the film strip processing equipment, the support platform 111 in the film strip support device 1 can support m film strips extending along the first direction, and the receiving component 122 in the film strip support device 1 can support the end of the film strip extending out of the support surface of the support platform 111, so as to prevent the end of the film strip from drooping downward due to gravity, thus ensuring the production efficiency and product quality of photovoltaic modules.

[0125] Optional, please continue reading Figure 6 The film strip processing equipment also includes n film-forming devices 2, each corresponding to a support platform 111. Each film-forming device 2 includes a film-laying mechanism 21, a cutting mechanism 22, and a traction mechanism 23, wherein:

[0126] The film-laying mechanism 21, the cutting mechanism 22, and the corresponding support platform 111 are arranged sequentially along the first direction;

[0127] Membrane dispensing mechanism 21 is used to release m membrane strips;

[0128] The traction mechanism 23 is used to clamp the ends of each film strip from the film dispensing mechanism 21 and pull the film strip along the first direction;

[0129] The support platform 111 is used to support the membrane strip located between the corresponding traction mechanism 23 and the cutting mechanism 22;

[0130] The cutting mechanism 22 is used to cut the film strip after it is received by the support table 111, with both ends of the film strip extending out of the support table 111 respectively;

[0131] The support mechanisms 12 at both ends of the support platform 111 are used to avoid the film strip when the traction mechanism 23 clamps the film strip and the cutting mechanism 22 cuts the film strip, and also to support the ends of the film strip after the traction mechanism 23 releases the film strip and the cutting mechanism 22 cuts the film strip.

[0132] Optionally, the working process of the membrane strip processing equipment of this application is as follows:

[0133] m membrane strips are released via membrane dispensing mechanism 21;

[0134] The traction mechanism 23 clamps the ends of each film strip from the film feeding mechanism 21 and moves along the first horizontal direction, so that the ends of the clamped film strips are away from the outlet end of the film feeding mechanism 21, and pulls the film strips out and through the cutting mechanism 22.

[0135] After the membrane strip is pulled out to the specified length, the support platform 111 in the membrane strip support device 1 moves to the bottom of the pulled-out membrane strip through the second drive assembly 113 to receive each membrane strip pulled out by the traction mechanism 23.

[0136] The cutting mechanism 22 cuts the film strip, thereby obtaining the cut film strip segment on the support platform 111 in the film strip carrying device 1;

[0137] After the traction mechanism 23 releases the membrane strip and the cutting mechanism 22 cuts the membrane strip, the support mechanisms 12 at both ends of the support platform 111 move to the support position to support the ends of the membrane strip.

[0138] Among them, the support mechanisms 12 at both ends of the bearing platform 111 are in a avoidance position when the traction mechanism 23 clamps the film strip and the cutting mechanism 22 cuts the film strip, so as to avoid interference with the cutting mechanism 22 and the traction mechanism 23.

[0139] The support mechanism 12 of this application avoids interference with the film strip when the traction mechanism 23 clamps the film strip and the cutting mechanism 22 cuts the film strip, and supports the end of the film strip after the traction mechanism 23 releases the film strip and the cutting mechanism 22 cuts the film strip. This design effectively avoids interference between the support mechanism 12 and the traction mechanism 23 and the cutting mechanism 22 during the film strip processing, ensuring smooth operation and production efficiency of the equipment. At the same time, the flexible avoidance and timely support of the support mechanism 12 prevents the sagging problem of the film strip end, improves the flatness of the film strip, and ultimately helps to improve the performance and quality of photovoltaic modules.
