AI Technical Summary
During the production line process, the encapsulant film of photovoltaic modules is prone to bulging, which can cause the cells to get stuck together. Current technology, such as adding rollers to flatten the encapsulant film in front of the typesetting machine, still cannot completely avoid bulging, resulting in production line shutdowns and cell losses.
A correction detection device is adopted, including a through-beam detection device and a correction mechanism, to detect the flatness of the adhesive film in real time and send an alarm signal when necessary. The correction mechanism applies a correction force to the adhesive film to ensure that the adhesive film is within a reasonable range and avoids bulging.
Effective detection and correction of encapsulant film bulges can prevent photovoltaic modules from getting stuck before entering the stacking machine, reducing production line downtime and cell loss, and improving production efficiency.

Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic technology, and in particular to calibration testing devices, production lines, and photovoltaic systems. Background Technology
[0002] Photovoltaic modules typically consist of glass, encapsulant film, solar cells, back glass, and backsheet. During the assembly line process, the encapsulant film of the photovoltaic module is prone to bulging due to vibration and other factors. Therefore, if the solar cell strings are placed on the encapsulant film, bulges will form, causing the modules to become stuck in the stacking machine, leading to scrap, production line shutdown, and cell fragmentation.
[0003] Currently, a possible solution to the aforementioned technical problem is to add rollers before the glass enters the encapsulation machine, flattening the encapsulation film as the photovoltaic modules travel, thus preventing the film from bulging and causing string jamming, resulting in defective and scrapped battery strings. However, adding rollers to flatten the encapsulation film before the encapsulation machine does not guarantee that the film will not bulge after exiting the encapsulation machine; there is still a high probability that bulging will occur, leading to string jamming. Utility Model Content
[0004] Therefore, it is necessary to provide a calibration detection device, an operating line, and a photovoltaic system to address the aforementioned technical problems.
[0005] This application provides a correction detection device configured for use in a photovoltaic system's operational assembly line. The assembly line includes an assembly line frame and an assembly line track located within the assembly line frame. The correction detection device includes:
[0006] The device fixing body is provided with a fixing part and a mounting part, and the device fixing body is configured to be fixedly assembled to the assembly line frame by means of the fixing part.
[0007] A through-beam detection device is configured to be mounted on a mounting part of the fixed body of the device, wherein the detection direction of the through-beam detection device is toward the assembly line track, for acquiring structural state information of the target object passing through the assembly line track.

[0011] In one embodiment, the correction detection device includes:
[0012] A correction mechanism is configured to be mounted on the assembly line frame to apply a correction force to a target object passing through the assembly line track, the correction force being configured to correct the target object to the track transport direction of the assembly line track.
[0013] In one embodiment, the correction mechanism includes:
[0014] A first corrective telescopic device is configured to be mounted on the assembly line frame and extend or retract toward the track transport direction of the assembly line track.
[0015] A second corrective telescopic device is configured to be mounted on the assembly line frame and extend or retract toward the track transport direction of the assembly line track.
[0016] In one embodiment, the correction detection device includes:
[0017] A blocking mechanism is configured to be mounted on the assembly line frame to prevent the target object from moving along the assembly line track.
[0018] In one embodiment, the blocking mechanism includes:

[0020] The second blocking telescopic device is configured to be mounted on the assembly line frame or the assembly line track, extend or retract toward the track transport plane of the assembly line track, and apply a blocking force to a target object passing through the assembly line track.
[0021] This application provides an operating production line for a photovoltaic system, the operating production line comprising:

[0028] In the aforementioned alignment detection device, production line, and photovoltaic system, when the encapsulant film of the photovoltaic module is transported along the aforementioned production line track, the through-beam detection device can be used to detect whether the upper surface of the encapsulant film has a flatness within a reasonable or specified range. If the upper surface of the encapsulant film does not reach the flatness within a reasonable or specified range, it can be determined that the upper surface of the encapsulant film has bulged. Thus, the surface flatness of the encapsulant film of the photovoltaic module can be detected before the photovoltaic module enters the stacking machine. If the encapsulant film of the photovoltaic module bulges, an alarm signal is sent to the corresponding alarm device based on the structural state information of the target object. The alarm device will then sound an alarm to remind personnel to handle the situation in a timely manner and avoid scrapping the photovoltaic module. Attached Figure Description

[0045] See Figures 1 to 5 As shown, this application provides an operating assembly line 100 for a photovoltaic system. The operating assembly line 100 includes an assembly line frame 2000, an assembly line track 3000, and a correction and detection device 1000. The assembly line track 3000 is assembled to the assembly line frame 2000, and the correction and detection device 1000 is assembled to at least one of the assembly line frame 2000 and the assembly line track 3000. The aforementioned alignment testing device 1000 is an operational production line 100 suitable for photovoltaic systems. The alignment testing device 1000 includes a device fixing body 1100 and a through-beam testing device 1200. The device fixing body 1100 is provided with a fixing part and a mounting part. For example, the mounting part can be located at the bottom of the device fixing body 1100, and the fixing part can be located at a suitable position such as the middle or top of the device fixing body 1100. Furthermore, both the fixing part and the mounting part can be selected according to actual needs, such as threaded mechanism, snap-fit mechanism, adhesive mechanism, riveting mechanism, etc., which can be used for fixed connection or for installing other compatible components. No limitation is made here.
[0046] Therefore, the device fixing body 1100 can be configured to be fixedly assembled to the assembly line frame 2000 via a fixing part, thereby realizing the assembly of the device fixing body 1100 relative to the assembly line frame 2000. Furthermore, after the device fixing body 1100 is assembled to the assembly line frame 2000, the device fixing body 1100 can be located in the lateral direction of the assembly line track 3000. At this time, the assembly line track 3000 can be defined to form a track transport direction, and the lateral direction of the assembly line track 3000 is a direction deviating from the track transport direction, such as the left or right side of the track transport direction.
[0047] For example, the assembly line frame 2000 has a central region and side regions located on the left and right sides of the central region. The central region of the assembly line frame 2000 is used to assemble the assembly line track 3000. The device fixing body 1100 is configured to be set in one of the side regions of the assembly line frame 2000, or simultaneously set in both side regions of the assembly line frame 2000.
[0048] The device fixing body 1100 can adopt a base, bracket or other structure. The device fixing body 1100 is set on the assembly line frame 2000 instead of the assembly line track 3000. This is because the device fixing body 1100 is on the assembly line frame 2000 and can be far away from the assembly line track 3000. When it is used to fix the through-beam detection device 1200, it can minimize the shaking of the photovoltaic module during the movement of the photovoltaic module on the assembly line track 3000, which may cause the through-beam detection device 1200 to make a detection error and avoid affecting production efficiency.
[0049] The through-beam detector 1200 can be configured to be mounted on the mounting portion of the device fixing body 1100, thereby assembling the through-beam detector 1200 relative to the device fixing body 1100. The detection direction of the through-beam detector 1200 can be defined to face the assembly line track 3000, for example, perpendicular to the track transport direction of the assembly line track 3000, so that the through-beam detector 1200 can be used to acquire structural state information of target objects passing through the assembly line track 3000.
[0050] The through-beam detection device 1200 includes a transmitting device 1210 and a receiving device 1220. In one embodiment, the device fixing body 1100 may include a first fixing body 1110 and a second fixing body 1120. The first fixing body 1110 is provided with a first fixing part and a first mounting part, and the second fixing body 1120 is provided with a second fixing part and a second mounting part. The first fixing body 1110 is configured to be assembled to the assembly line frame 2000 via the first fixing part, and the second fixing body 1120 is configured to be assembled to the assembly line frame 2000 via the second fixing part. The first fixing body 1110 and the second fixing body 1120 are located on symmetrical sides of the assembly line track 3000.
[0051] At this time, the transmitting device 1210 is configured to be mounted on the first mounting portion of the first fixed body 1110, and the receiving device 1220 is configured to be mounted on the second mounting portion of the second fixed body 1120. Based on the symmetrical arrangement of the first fixed body 1110 and the second fixed body 1120 on both sides of the assembly line track 3000, the signal transmitted by the transmitting device 1210 can be received by the receiving device 1220, thereby realizing the detection function of the through-beam detection device 1200. Those skilled in the art can use various types of through-beam detection devices 1200; for example, the through-beam detection device 1200 can be a through-beam photoelectric sensor as needed, and this is not limited here.
[0052] In one embodiment of this application, the target object may be configured as the encapsulant film of a photovoltaic module, and the aforementioned structural state information may include information on whether the surface of the encapsulant film has bulges. Therefore, when the encapsulant film of the photovoltaic module is transported along the aforementioned assembly line track 3000, the through-beam detector 1200 can be used to detect whether the upper surface of the encapsulant film has a flatness within a reasonable or specified range. If the upper surface of the encapsulant film does not reach the flatness within a reasonable or specified range, it can be determined that the upper surface of the encapsulant film has bulged.
[0053] Therefore, the aforementioned correction detection device 1000 can detect the surface flatness of the photovoltaic module's encapsulant film before the photovoltaic module enters the stacking machine. If the encapsulant film of the photovoltaic module bulges, an alarm signal is sent to the corresponding alarm device based on the structural state information of the target object. The alarm device will then sound an alarm to remind personnel to handle the situation in a timely manner and avoid scrapping the photovoltaic module.
[0054] In one embodiment, the alignment detection device 1000 further includes an alignment mechanism 1300, which is configured to be mounted on the assembly line frame 2000 to apply a alignment force to the target object passing through the assembly line track 3000, thereby aligning the target object with the track transport direction of the assembly line track 3000. This ensures that the photovoltaic modules are aligned in the previous section of the assembly line 100 before entering the stacking machine, preventing the photovoltaic modules from being impacted or scrapped due to vibration and displacement, and thus avoiding the problem of battery strings being hung up due to encapsulation film issues.
[0055] The correction mechanism 1300 can employ various mechanisms capable of applying a correction force, such as a telescopic cylinder, a lead screw mechanism, or a linkage mechanism. For example, the correction mechanism 1300 includes a first correction telescopic device 1310 and a second correction telescopic device 1320. The first correction telescopic device 1310 is configured to be mounted on the assembly line frame 2000 and then telescopically extends or retracts in a direction perpendicular to the track transport direction of the assembly line track 3000. Simultaneously, the second correction telescopic device 1320 is configured to be mounted on the assembly line frame 2000 and then telescopically extends or retracts in a direction perpendicular to the track transport direction of the assembly line track 3000.
[0056] The first corrective telescopic device 1310 and the second corrective telescopic device 1320 are located on the symmetrical sides of the assembly line track 3000. The first corrective telescopic device 1310 and the second corrective telescopic device 1320 are used for relative telescopic expansion and contraction. The relative telescopic expansion and contraction of the first corrective telescopic device 1310 and the second corrective telescopic device 1320 can apply a corrective force to the left or right side of the target object passing through the assembly line track 3000 in the left or right direction of the target object.
[0057] In one embodiment, the correction detection device 1000 may further include a blocking mechanism 1400, which is configured to be mounted on the assembly line frame 2000 to block the target object from moving along the assembly line track 3000. This blocking mechanism prevents the photovoltaic module from overrunning due to delays in the operation of the assembly line 100, thus preventing the photovoltaic module from being properly corrected by the correction mechanism 1300 and avoiding collisions with glass or machine equipment.
[0058] The blocking mechanism 1400 can employ various mechanisms capable of applying a blocking force, such as a telescopic cylinder, a lead screw mechanism, or a linkage mechanism. For example, the blocking mechanism 1400 includes a first blocking telescopic device 1410 and a second blocking telescopic device 1420. The first blocking telescopic device 1410 is configured to be mounted on the assembly line frame 2000 or the assembly line track 3000. The first blocking telescopic device 1410 then extends or retracts toward a track transport plane perpendicular to the assembly line track 3000, thereby applying a blocking force to a target object passing through the assembly line track 3000. For example, it extends upwards, exceeding the height of the assembly line track 3000, thus blocking the target object. The second blocking telescopic device 1420 is configured to be mounted on the assembly line frame 2000 or the assembly line track 3000. The second blocking telescopic device 1420 is then used to extend or retract toward the track transport plane perpendicular to the assembly line track 3000, thereby applying a blocking force to the target object passing through the assembly line track 3000, for example, extending upwards from below and exceeding the height of the assembly line track 3000, thereby blocking the target object.
[0059] This application provides a photovoltaic system, which includes the aforementioned calibration and testing device 1000, or the aforementioned operating production line 100. Since the specific structure, functional principle, and technical effects of the aforementioned calibration and testing device 1000 and the aforementioned operating production line 100 have been described in detail above, they will not be repeated here. Any technical details regarding the aforementioned calibration and testing device 1000 and the aforementioned operating production line 100 can be found in the foregoing description.
[0060] 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.
[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent 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 patent application should be determined by the appended claims.
