[0002] Photovoltaic module processing is a crucial component of the solar photovoltaic industry chain. By encapsulating thin solar cells individually, they ensure reliable operation in harsh outdoor environments. The current mainstream photovoltaic module processing process typically utilizes EVA film encapsulation and involves multiple steps, including cell inspection, individual cell soldering, cell string soldering, module stacking, module lamination, frame and junction box installation, finished product testing, and packaging and warehousing. Because each process is closely linked, the level of craftsmanship in each directly impacts product quality and grade.

[0003] In the related art, after the photovoltaic module stacking step and before the photovoltaic module lamination step, an edge sealing device is usually required to seal the edges of the photovoltaic module, that is, edge sealing tape is used to stick and seal the long and short sides of the photovoltaic module respectively.

[0004] However, transparent tape is often used as edge-sealing tape, which can transmit light signals and easily cause detection anomalies. As a result, the sensing instrument cannot accurately and quickly detect the remaining amount of edge-sealing tape, resulting in reduced edge-sealing efficiency. Utility Model Content

[0026] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0027] See Figure 1 and Figure 2 , Figure 1 A diagram showing the working state of an edge sealing device according to an embodiment of the present application is shown. Figure 2 Shown Figure 1The structural diagram of the photovoltaic component 30 is hidden in the structure shown. An embodiment of the present application provides an edge sealing device, which includes an edge sealing tape remainder detection mechanism 10. Specifically, the edge sealing tape remainder detection mechanism 10 includes: a base 11, a movable member 12 and a distance measuring component 13. The movable member 12 is movably arranged on the base 11, and the movable member 12 is provided with an abutting portion 14 for abutting against the outer circle of the edge sealing tape 20. The distance measuring component 13 includes a distance measuring sensor 131 and a matching member 132 that mutually senses and cooperates with the distance measuring sensor 131. One of the distance measuring sensor 131 and the matching member 132 is arranged on the base 11, and the other is arranged on the movable member 12. The distance measuring sensor 131 is used to sense the distance between the distance measuring sensor 131 and the matching member 132.

[0028] When using the aforementioned edge-sealing device and edge-sealing tape remaining quantity detection mechanism 10, the position of the movable member 12 is adjusted so that the abutting portion 14 abuts the outer circumference of the edge-sealing tape 20. The distance-measuring sensor 131 senses the distance between itself and the mating member 132. Based on the distance sensed by the distance-measuring sensor 131, the remaining quantity of the edge-sealing tape 20 can be inferred. Thus, the remaining quantity of the edge-sealing tape 20 is detected by contact measurement between the abutting portion 14 and the outer circumference of the edge-sealing tape 20. This effectively avoids the defect in related art where detection failure occurs due to the transparency of the edge-sealing tape 20. The remaining quantity of the edge-sealing tape 20 is detected with high accuracy, resulting in higher edge-sealing efficiency. Furthermore, the overall structure is simple and reliable, with low maintenance costs.

[0029] It should be noted that the margin of the edge-sealing tape 20 refers to the length of the remaining material of the edge-sealing tape 20 when it is fully unfolded. The margin of the edge-sealing tape 20 gradually decreases with use.

[0030] In some embodiments, the distance measuring sensor 131 includes, but is not limited to, a laser rangefinder, an ultrasonic rangefinder, or a magnetic sensor, and can be flexibly selected and configured according to specific needs. Furthermore, the matching component 132 includes, but is not limited to, a baffle. During testing, after the distance measuring signal from the distance measuring sensor 131 is incident on the matching component 132, the matching component 132 acts as a reflector, reflecting the distance measuring signal to the distance measuring sensor 131. The distance measuring sensor 131 can sense the distance between itself and the matching component 132 based on the distance measuring signal. Furthermore, the remaining amount of the edge-sealing tape 20 can be calculated based on the distance between the distance measuring sensor 131 and the matching component 132.

[0031] For the laser rangefinder, the distance between the laser rangefinder and the matching component 132 refers to the distance between the end face of the transceiver end of the laser rangefinder and the plate surface of the matching component 132 .

[0032] See also Figures 1 to 3In some embodiments, the edge banding device further includes an edge banding machine 40. When edge banding the photovoltaic module 30, the edge banding machine 40 moves along the edge 31 of the photovoltaic module 30, driving the edge banding tape 20 to adhere to the edge 31 of the photovoltaic module 30. As the edge banding tape 20 is dragged, it rotates around its center and releases the edge banding tape 20 accordingly. The edge banding tape remaining amount detection mechanism 10 is mounted on the edge banding machine 40. Specifically, the base 11 is mounted and fixed to the edge banding machine 40. It can be detachably connected to the edge banding machine 40 using fasteners such as pins, rivets, and screws, or it can be non-detachably connected to the edge banding machine 40 by bonding, welding, or clamping.

[0033] See also Figures 1 to 3 Optionally, the edge banding machine 40 is provided with a rotatable support plate 41. The support plate 41 is used to support the edge banding tape 20. During use, the edge banding tape 20 is supported by the support plate 41 and can drive the support plate 41 to rotate synchronously during the unwinding process. The edge banding tape 20 is rotatably mounted on the edge banding machine 40. During rotation, the excess amount of the edge banding tape 20 decreases accordingly, and the position of the rotation center of the edge banding tape 20 on the edge banding machine 40 remains relatively unchanged.

[0034] Specifically, the example of a distance-measuring sensor 131 mounted on the base 11 and a correspondingly mounted mating member 132 on the movable member 12 will be described. In this case, the position of the distance-measuring sensor 131 on the edge banding machine 40 remains unchanged, and the distance between the distance-measuring sensor 131 and the rotational center of the edge-banding tape 20 remains unchanged. The contact position between the abutting portion 14 of the movable member 12 and the edge-banding tape 20 gradually approaches the rotational center of the edge-banding tape 20 as the remaining amount of the edge-banding tape 20 decreases, causing the distance between the mating member 132 and the distance-measuring sensor 131 to gradually increase. When the remaining amount of the edge-banding tape 20 decreases to a first predetermined value, the distance between the mating member 132 and the distance-measuring sensor 131 correspondingly increases to a second predetermined value. In other words, when it is detected that the distance between the fitting 132 and the distance measuring sensor 131 reaches the second preset value, it can be determined that the remaining amount of the edge banding tape 20 has decreased to the first preset value, and the unwinding operation is stopped in time, so that the remaining amount of the edge banding tape 20 can be controlled at the first preset value.

[0035] It should be noted that the first preset value and the second preset value can be flexibly adjusted and set according to actual needs, and are not limited here. Taking the first preset value as an example, it can be set according to the requirements for the margin size of the edge-sealing tape 20 in actual production. For example, when the margin size of the edge-sealing tape 20 is required to be less than 5cm, the first preset value is set to 5cm. In this way, when the ranging sensor determines that the first preset value of the edge-sealing tape 20 is 5cm, the alarm device issues an alarm. It is understandable that the first preset value can also be set to 6cm, 7cm or 8cm, etc. as needed. In some embodiments, the first preset value is any value between 3cm and 10cm, and the specific value of the first preset value is not limited here.

[0036] See also Figure 1 、 Figure 2 and Figure 4 In some embodiments, the abutting portion 14 includes a rolling member 141 rotatably arranged on one end of the movable member 12 close to the edge-sealing tape 20. The rolling member 141 includes but is not limited to a pressure wheel or a rolling ball, etc. The rolling member 141 is used to abut against the outer circle of the edge-sealing tape 20. Specifically, the rolling member 141 is a pressure wheel, and the wheel surface of the pressure wheel abuts against the outer circle of the edge-sealing tape 20. While abutting against the outer circle of the edge-sealing tape 20, the rolling member 141 can adaptively rotate with the use of the edge-sealing tape 20, and the obstruction to the discharge of the edge-sealing tape 20 is small. The edge-sealing tape 20 can be used normally while measuring the margin, that is, the margin detection of the edge-sealing tape 20 can be performed while the photovoltaic module 30 is edge-sealed.

[0037] See also Figure 4 In addition to the above embodiment, the contact portion 14 further includes a mounting bracket 142 mounted on the movable member 12. The rolling member 141 is rotatably mounted on the mounting bracket 142. The mounting bracket 142 includes two support arms spaced apart from each other, and the opposite ends of the rolling member 141 are rotatably connected to the two support arms.

[0038] See also Figure 2 and Figure 4 In one embodiment, the edge-sealing tape remainder detection mechanism 10 further includes an elastic member 15. The elastic member 15 is connected between the movable member 12 and the base 11, and is used to elastically press the contact portion 14 against the outer circumference of the edge-sealing tape 20. In this way, as the remainder of the edge-sealing tape 20 gradually decreases, the elastic force provided by the elastic member 15 can enable the contact portion 14 to always elastically press against the outer circumference of the edge-sealing tape 20, thereby enabling the photovoltaic module 30 to be edge-sealed while the remainder of the edge-sealing tape 20 can be detected simultaneously. This results in a high accuracy rate in detecting the remainder of the edge-sealing tape 20 and a high efficiency in edge sealing.

[0039] In one embodiment, a movable hole 111 is provided on the base 11, and the movable member 12 is movably inserted into the movable hole 111 along its length direction. The elastic member 15 includes a spring sleeved on the movable member 12, and the opposite ends of the elastic member 15 are respectively in contact with the matching member 132 and the base 11. Among them, the elastic member 15 is specifically a compression spring. Under the elastic force of the elastic member 15, the abutting portion 14 of the movable member 12 elastically presses on the outer circle of the edge-sealing tape 20. When the edge-sealing tape 20 rotates around its central axis to discharge the material, the rolling member 141 can rotate together with the edge-sealing tape 20. As the edge-sealing tape 20 is used, the excess of the edge-sealing tape 20 gradually decreases, and the outer diameter of the edge-sealing tape 20 also gradually decreases. At this time, the matching member 132 gradually moves away from the laser rangefinder under the elastic force of the elastic member 15.

[0040] In some embodiments, the moving member 12 includes but is not limited to a moving rod, a moving shaft, a moving column, or the like.

[0041] In one embodiment, there are at least two movable members 12, at least two movable holes 111, and at least two elastic members 15. Each movable member 12 is correspondingly inserted into each movable hole 111, and each elastic member 15 is correspondingly sleeved on each movable member 12. In addition, there is one fitting member 132, which is connected to each movable member 12, so that the fitting member 132 is stably mounted on the movable member 12.

[0042] Of course, as some optional solutions, the number of elastic parts 15 can also be less than the number of moving parts 12, for example, set to one, so that the elastic part 15 can be installed on at least one moving part 12, and there is no need to install the elastic part 15 on each moving part 12.

[0043] In one embodiment, an anti-slip portion 121 is provided on one end of the moving member 12 away from the fitting 132. Thus, the anti-slip portion 121 acts as a limiter to prevent the end of the moving member 12 away from the fitting 132 from passing through the movable hole 111 and escaping from the base 11.

[0044] In one embodiment, the edge tape remaining amount detection mechanism 10 further includes a controller and an alarm. Both the distance sensor 131 and the alarm are electrically connected to the controller. When the controller determines that the remaining amount of edge tape 20 is less than or equal to a first preset value, the controller controls the alarm to activate an alarm, thereby promptly replacing the edge tape 20. The alarm's alarm action may include, but is not limited to, voice, light, vibration, or display, as long as it provides a warning effect.

[0045] In the related art, when photovoltaic modules are sealed with edge-sealing tape, the edge-sealing tape position is prone to deviation defects, resulting in loose edge sealing, which in turn leads to serious glue overflow after lamination of photovoltaic modules, thus causing abnormal quality problems of photovoltaic modules. Abnormal edge sealing will cause the following types of problems: (1) Serious glue overflow during module lamination: Due to serious glue overflow after lamination, the modules are contaminated and need to be cleaned manually. (2) Split photovoltaic modules: Due to the inability to effectively seal after the film melts during lamination, the melted film is lost, causing bubbles and hollows on the edge of the photovoltaic module, further leading to splitting of the cell after lamination. (3) Reduced peel strength: Due to the loss of edge glue, the peel strength of the edge of the photovoltaic module is reduced. (4) Impact on frame assembly: During frame assembly, due to the residual glue on the surface of the photovoltaic module after glue overflow, the frame will be stuck, blocked, etc., which may seriously cause the frame to be squeezed and deformed. (5) Increased frequency of cleaning of the high-temperature cloth of the laminator: Due to the overflow of glue during the lamination process, the high-temperature cloth of the laminator is contaminated. In order to prevent residual colloid from affecting other components, the frequency of cleaning the laminator's high-temperature cloth needs to be increased.

[0046] See also Figure 1 and Figure 2 Based on this, in this embodiment, the edge banding machine 40 is provided with a rotatable support plate 41. The support plate 41 is used to support the edge banding tape 20. Specifically, when assembling the edge banding tape 20, an edge banding tape 20 with a bottom surface dimension smaller than the supporting surface dimension of the support plate 41 is selected. This allows the edge banding tape 20 to be uniformly supported by the support plate 41 after being placed on the support plate 41. The support plate 41 effectively prevents abnormalities such as sagging of the edge banding tape 20, improves the stability of the edge banding tape 20 during unwinding, and thus ensures more precise edge banding positioning and enhanced product quality.

[0047] Optionally, the support surface of the support plate 41 includes, but is not limited to, a circular, rectangular, or other shape, and the bottom surface of the edge-sealing tape 20 includes, but is not limited to, a circular, rectangular, or other shape. For example, if the support surface of the support plate 41 is circular and the bottom surface of the edge-sealing tape 20 is circular, the diameter of the support surface of the support plate 41 is greater than the diameter of the bottom surface of the edge-sealing tape 20.

[0048] To prevent the support plate 41 from deformation and damage due to stress, the support plate 41 may optionally include, but is not limited to, a metal plate such as stainless steel, iron, aluminum, or copper, or other non-metallic plates made of hard materials. In this embodiment, the support plate 41 is specifically made of stainless steel, which is less prone to deformation and rusting under stress, and has a long service life.

[0049] In addition, the support surface of the support plate 41 is set to be flat, and the edge sealing tape 20 is placed on the support surface of the support plate 41, taking the form of flat support, which can form stable support for various parts of the edge sealing tape 20 along its radial direction.

[0050] In one embodiment, at least one photoelectric sensing hole 411 is formed on the support plate 41. The edge banding machine 40 is further provided with a tape sensor located below the support plate 41 and corresponding to the photoelectric sensing hole 411. The tape sensor is used to sense whether the edge banding tape 20 is present at the photoelectric sensing hole 411 on the support plate 41.

[0051] It should be noted that the position corresponding setting means that the support plate 41 rotates around its central axis, and the photoelectric sensing detection hole 411 can be rotated to a position relative to the upper and lower parts of the tape sensor, so that the detection signal of the tape sensor can pass through the photoelectric sensing detection hole 411 to detect the edge banding tape 20 on the support plate 41.

[0052] When the tape sensor senses that there is edge-sealing tape 20 at the photoelectric sensing detection hole 411 on the support plate 41, it means that there is sufficient remaining edge-sealing tape 20; conversely, when the tape sensor senses that there is no edge-sealing tape 20 at the photoelectric sensing detection hole 411 on the support plate 41, it means that there is insufficient remaining edge-sealing tape 20, and a warning operation is performed, so that the edge-sealing tape 20 is replaced in time.

[0053] Specifically, the tape sensor is electrically connected to the controller. Not only can the edge tape remaining amount detection mechanism 10 detect the remaining amount of the edge tape 20, but the tape sensor can also detect the remaining amount of the edge tape 20, thereby improving the accuracy of the remaining amount detection of the edge tape 20.

[0054] In some embodiments, the number of photoelectric sensing detection holes 411 is, for example, two, three, four, or more, which can be flexibly adjusted and configured according to actual needs and is not limited herein. Furthermore, the photoelectric sensing detection holes 411 include, but are not limited to, waist-shaped holes or holes of other shapes arranged circumferentially around the center of the support plate 41.

[0055] See also Figure 1 、 Figure 2 and Figure 4 In one embodiment, the edge banding machine 40 includes a support plate 42 and a fixing base 43 rotatably disposed on the support plate 42 . The support disc 41 is disposed on the fixing base 43 . The base 11 is disposed on the support plate 42 .

[0056] In some embodiments, the support plate 41 is fixedly connected to the fixing base 43 by various fasteners, including but not limited to snap-fitting, bonding, welding, or pins, rivets, screws, etc. In this embodiment, to facilitate assembly and disassembly of the support plate 41 and to facilitate replacement of a desired type of support plate 41, the support plate 41 is mounted on the fixing base 43 by snap-fitting. Specifically, the fixing base 43 is provided with at least one or more first snap-fitting portions 431, and the support plate 41 is provided with second snap-fitting portions that snap-fit ​​and securely engage with the first snap-fitting portions 431.

[0057] When the first clamping portion 431 is configured as a clamping block, the second clamping portion is configured as a clamping hole that is clamped with the clamping block; when the first clamping portion 431 is configured as a clamping hole, the second clamping portion is configured as a clamping block that is clamped with the clamping hole.
