Abstract
Description
Technical Field
[0001] This application relates to the field of trimming technology, and in particular to a trimming device. Background Technology
[0002] Photovoltaic modules consist of a backsheet, encapsulant layer, solar cells, encapsulant layer, and top panel, all laminated together. After lamination and melting, they are firmly bonded together. Following frame and junction box installation and performance testing, the finished product is ready for warehousing. In actual production, after the modules pass through the laminator, the melted encapsulant overflows and solidifies from the gaps between the modules. Therefore, a trimming device is needed to remove the excess encapsulant strips to avoid affecting subsequent frame installation. However, traditional trimming devices do not collect the removed encapsulant strips; they naturally fall below the equipment, potentially hanging on protruding parts or stuck in grooves, increasing the difficulty of cleaning and severely impacting trimming efficiency.

[0032] In traditional technology, after the trimming device removes the excess adhesive strip from the edge of the component, the strip falls off onto the base plate below the device, and then is manually cleaned after the machine is stopped. The disadvantage of this method is that the adhesive strip may get caught on protruding parts, potentially affecting equipment operation if not detected in time. Furthermore, during manual cleaning, due to the longer distance on the longer side, it is difficult for personnel to clean the adhesive strip located deep within the parts, requiring the use of hooks, which is not only inefficient but also poses safety hazards.
[0033] Based on this, this application provides a trimming device, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the trimming device includes a trimming mechanism 100 and a collecting mechanism 200.
[0034] The trimming mechanism 100 includes a shelf 110 and a trimmer, with the trimmer mounted on it. The trimmer is used to trim the edges of the parts to be processed placed on the shelf 110. The collection mechanism 200 includes a collection trough 210 and a scraper assembly 220. The collection trough 210 is arranged circumferentially along the parts to be processed. The scraper assembly 220 includes a driver 221 and a scraper 222. The driver 221 is disposed in the collection trough 210, and the scraper 222 is connected to the driver 221. The driver 221 is used to drive the scraper 222 to move along the collection trough 210 to clean the scraps in the collection trough 210.
[0035] This application provides a collection trough 210 around the device to be processed. When the trimmer processes the device, the material removed can fall into the collection trough 210 for collection. Then, the driver 221 drives the scraper 222 to move along the collection trough 210 to clean and discharge the material in the collection trough 210, thereby realizing automatic cleaning of the trimming device, effectively improving cleaning efficiency and reducing the difficulty of manual cleaning.
[0036] It is understood that the edge trimmer in this application only needs to be able to trim the edges of the device. For example, the edge trimmer may include an edge trimmer blade, which is used to trim the edges of the device according to a preset size.
[0037] In some embodiments, such as Figure 4 As shown, the collection tank 210 includes at least two first collection tanks 211 and at least two second collection tanks 212, wherein the two first collection tanks 211 are respectively arranged along the length direction of the device to be processed, and the two second collection tanks 212 are respectively arranged along the width direction of the device to be processed, and the scraper assembly 220 is at least disposed in the first collection tank 211.
[0038] Understandably, the first collection trough 211 is respectively positioned on opposite sides of the device to be processed, and the second collection trough 212 is also respectively positioned on opposite sides of the device to be processed. The first collection trough 211 and the second collection trough 212 surround the device to be processed, thereby collecting the material removed from the edges of the device. Since the first collection trough 211 is relatively long, it is difficult to clean the adhesive strip located deep within it. Therefore, a scraper assembly 220 is provided within the first collection trough 211 to effectively improve cleaning efficiency. Furthermore, if the second collection trough 212 is also relatively long, a scraper assembly 220 can also be provided within the second collection trough 212; if the second collection trough 212 is short and easy to clean manually, a scraper assembly 220 may not be required.
[0039] In some embodiments, such as Figure 4 The collection trough 210 also includes at least two discharge gates 213, which are located at the connection between the first collection trough 211 and the second collection trough 212. By placing the discharge gates 213 at the connection between the first collection trough 211 and the second collection trough 212, this application allows for simultaneous collection from both troughs during the cleaning process, and facilitates the centralized cleaning of materials removed after trimming.
[0040] In some embodiments, such as Figure 1 and Figure 2 As shown, a guide plate 214 is inclinedly arranged on the side of the collection tank 210 near the shelf 110. The guide plate 214 is arranged along the length of the collection tank 210, and the inclined direction of the guide plate 214 faces one side of the shelf 110. Optionally, a smooth layer is provided on the surface of the guide plate 214 to reduce the probability of the removed material sticking to the guide plate 214. By providing an inclined guide plate 214 on the side of the collection tank 210 near the device to be processed, the material to be trimmed can slide directly into the collection tank 210 along the guide plate 214, further avoiding problems such as material sticking to the wall. Moreover, the guiding effect of the guide plate 214 improves the concentration of the trimmed material, thereby improving the cleaning efficiency.
[0041] In some embodiments, such as Figure 3 and Figure 5As shown, the drive unit 221 includes a first drive member 2211, a conveyor belt 2212, and a connector 2213. The conveyor belt 2212 is arranged along the length of the collection trough 210. The first drive member 2211 is connected to the conveyor belt 2212 and is used to drive the conveyor belt 2212 to move. One end of the connector 2213 is fixedly disposed on the conveyor belt 2212, and the other end is connected to the scraper 222. Optionally, the inner side of the conveyor belt 2212 is provided with meshing teeth, and the first drive member 2211 engages with the meshing teeth to avoid slippage of the conveyor belt 2212. In this application, the scraper 222 is fixed to the conveyor belt 2212 by the connector 2213, ensuring the stability of the scraper 222 during the cleaning process.
[0042] Understandably, during the collection process, the conveyor belt 2212 moves forward, thereby driving the scraper 222 to clean the material in the collection trough 210. After cleaning, the conveyor belt moves in the reverse direction, thereby driving the scraper 222 back to its initial position. This reciprocating movement achieves the cleaning and resetting of the scraper 222.
[0043] In some embodiments, the first drive element 2211 may be a motor.
[0044] In some embodiments, the driver 221 further includes a slide rail 2214 arranged along the length of the collection trough 210, and a slider 2215 is provided on the connector 2213, the slider 2215 being slidably disposed within the slide rail 2214. In this application, during the movement of the scraper 222 driven by the conveyor belt 2212, the slide rail 2214 provides guidance for the movement of the scraper 222, further preventing the scraper 222 from deviating during movement and reducing the risk of the scraper 222 scraping against the inner wall of the collection trough 210. Furthermore, by providing the slider 2215 on the connector 2213 and connecting the slider 2215 to the slide rail 2214, the connector 2213 can be supported by the slide rail 2214, thereby improving the structural strength of the connector 2213 and further ensuring the stability of the scraper 222 during operation.
[0045] In some embodiments, the driver 221 further includes a second driving member (not shown in the figure), which is disposed on the slide rail 2214. The second driving member is used to drive the slide rail 2214 to move, thereby adjusting the distance between the scraper 222 and the bottom of the collection trough 210. This application adjusts the distance between the scraper 222 and the bottom of the collection trough 210 by using the second driving member. When the scraper 222 deviates or material becomes stuck between the scraper 222 and the collection trough 210 and cannot move, the second driving member raises the slide rail 2214, thereby raising the scraper 222 and eliminating the state where the scraper 222 is stuck and cannot move.
[0046] Understandably, after adjustment of the second drive component, the scraper 222 can be reset and cleaning can be performed again; alternatively, the machine can be stopped for maintenance.
[0047] Optionally, the second drive component includes multiple telescopic devices disposed on the slide rail 2214, such as cylinders or hydraulic cylinders.
[0048] In some embodiments, such as Figure 5 As shown, a fixing member is provided on the side of the connector 2213 that connects to the conveyor belt 2212. The fixing member includes two opposing clamping plates 2216, which clamp the conveyor belt 2212 and fix the connector 2213. This application uses the clamping plates 2216 to fix the connector 2213 to the conveyor belt 2212, increasing the contact area between the connector 2213 and the conveyor belt 2212, ensuring connection stability, and preventing the scraper 222 from shaking during movement.
[0049] Optionally, the clamping plate 2216 is provided with a bolt assembly, and a through hole is opened in the conveyor belt 2212. The bolt passes through the conveyor belt 2212 to screw and fix the clamping plate 2216 and the conveyor belt 2212. The clamping plate 2216 is fixed in the above manner, which can further prevent slippage between the clamping plate 2216 and the conveyor belt 2212.
[0050] It is understandable that a friction layer can be provided on the side of the clamping plate 2216 near the conveyor belt 2212 to increase the friction between the clamping plate 2216 and the conveyor belt 2212, thereby improving the connection stability.
[0051] In some embodiments, an extension 2217 is provided on the side of the connector 2213 connected to the scraper 222. The extension 2217 is provided along the length direction of the collection groove 210 and extends away from the shelf 110. The scraper 222 is disposed on the extension 2217. By providing the extension 2217, this application enables the scraper 222 to be located outside the material drop collection area of the device to be processed in the reset state, thus preventing the trimmed material from falling onto the scraper 222 and affecting the cleaning effect.
[0052] In some embodiments, a brush is provided on the edge of the scraper 222. The brush provided on the edge of the scraper 222 can clean the debris in the collection tank 210, keep the inside of the collection tank 210 clean, and reduce the jamming between the scraper 222 and the collection tank 210 caused by debris accumulation.
[0053] In some embodiments, the trimming mechanism 100 further includes a blowing element disposed on the trimmer, which is used to blow away debris from the surface of the device to be processed. This application improves the cleanliness of the device surface by using a blowing element disposed on the trimmer to remove debris from the surface of the device to be processed.
[0054] In some embodiments, the trimmer includes a first trimmer and a second trimmer. The first trimmer is used to trim the length of the device to be processed, and the second trimmer is used to trim the width of the device to be processed. This application provides a first trimmer and a second trimmer to process the length and width of the device to be processed, effectively ensuring trimming accuracy.
[0055] In some embodiments, the scraper 222 has the same shape as the cross-sectional shape of the collection tank 210, and the scraper 222 is at a certain distance from the bottom surface and sidewall of the collection tank 210.
[0056] Exemplarily, a method for cleaning excess adhesive at the edges of a photovoltaic module after lamination using the aforementioned trimming device is provided, comprising the following steps:
[0057] S1. Transfer the photovoltaic module to the trimmer and use the trimmer to remove the excess adhesive on the long and wide sides of the photovoltaic module. The removed adhesive strip slides down the guide plate 214 into the collection tank 210.
[0058] S2. Start the first drive unit 2211 to drive the conveyor belt 2212 to rotate in the forward direction, so that the scraper 222 moves along the collection trough 210 and pushes the rubber strip in the collection trough 210 to the discharge gate 213 for cleaning. After cleaning is completed, the first drive unit 2211 drives the conveyor belt 2212 to rotate in the reverse direction, so that the scraper 222 is reset and ready for the next cleaning operation.
[0059] S3. When the scraper 222 gets stuck and cannot move during the cleaning process, the second drive unit is activated to lift the slide rail 2214, thereby raising the scraper 222. Then, the first drive unit 2211 is used to reset the scraper 222, or the machine is stopped for repair.
[0060] It is understandable that during the cleaning process, some of the removed adhesive strips may fall onto the scraper 222, affecting the cleaning effect. Therefore, trimming should not be performed during the cleaning process. Alternatively, the trimming mechanism 100 can be stopped during the cleaning process, or the adhesive strips in the collection tank 210 can be cleaned during the intervals when replacing photovoltaic modules, thereby effectively improving processing efficiency.
[0061] In summary, this application provides a collection trough 210 around the device to be processed. When the trimmer processes the device, the material removed can fall into the collection trough 210 for collection. Then, the driver 221 drives the scraper 222 to move along the collection trough 210 to clean and discharge the material in the collection trough 210, thereby realizing automatic cleaning of the trimming device, effectively improving cleaning efficiency and reducing the difficulty of manual cleaning.
[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0063] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
