[0035] In addition, if the terms "first", "second" appear, these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, if the term "multiple" appears, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise specifically limited.

[0038] It should be noted that if an element is referred to as "fixed to" or "provided to" another element, it can be directly on another element or there can be a middle element. If an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element.

[0039] As described above, in the conventional film strip conveying process, the reflective film strip is prone to folding during conveying from the barrel to the film pasting position, which affects the power generation after the reflective film strip is pasted to the photovoltaic module. The inventor found through creative labor that the reason is that the reflective film strip needs to pass through a plurality of transition shafts arranged longitudinally first, and then pass through a plurality of rollers arranged transversely during conveying from the barrel to the film pasting position, and the axial direction of the transition shafts is perpendicular to the axial direction of the rollers. Therefore, when the reflective film strip enters the rollers from the transition shafts, the surface of the reflective film strip needs to be turned by 90° to cooperate with the rollers. However, since the reflective film strip is very thin, and there is a long distance between the transition shafts and the rollers, the reflective film strip may not be able to accurately turn by 90° during actual work, for example, the surface of the reflective film strip is not rotated by 90° or more than 90°, which causes the reflective film strip to fold, and the reflective film strip cannot enter the rollers in a flat posture, thereby affecting the effect of pasting the reflective film strip to the photovoltaic module.
[0040] Based on this, an embodiment of the present application provides a film tape conveying device for conveying a film tape 50 such as a reflective film tape. Understandably, the film tape conveying device can also be used to convey other belt-shaped objects such as adhesive tapes and paper tapes. Figure 1 and Figure 2 The film tape conveying device of an embodiment includes a cartridge 10, a first conveying mechanism 20, a second conveying mechanism 30, and a positioning mechanism 40. The cartridge 10 is used to output the film tape 50. The first conveying mechanism 20 is used to receive the film tape 50 output by the cartridge 10. The first conveying mechanism 20 includes at least one first transition piece 21, which has a first cylindrical surface 211 for contact with the film tape 50. The second conveying mechanism 30 is arranged apart from the first conveying mechanism 20. The second conveying mechanism 30 is used to receive the film tape 50 output by the first conveying mechanism 20. The first conveying mechanism 20 includes at least one second transition piece 31, which has a second cylindrical surface 311 for contact with the film tape 50. The axial direction of the second cylindrical surface 311 is arranged at an angle with respect to the axial direction of the first cylindrical surface 211. Figure 3 The positioning mechanism 40 includes a positioning piece 41 arranged between the first conveying mechanism 20 and the second conveying mechanism 30. The positioning piece 41 has a third cylindrical surface 411 for contact with the film tape 50. The axial direction of the third cylindrical surface 411 is parallel to the axial direction of the second cylindrical surface 311.
[0041] In the above film tape conveying device, after the film tape 50 is output from the cartridge 10, it is first conveyed by the first transition piece 21 of the first conveying mechanism 20 and then conveyed by the second transition piece 31 of the second conveying mechanism 30. Because the axial direction of the first cylindrical surface 211 of the first transition piece 21 is arranged at an angle with respect to the axial direction of the second cylindrical surface 311 of the second transition piece 31, the film tape 50 will be turned when it is transferred from the first conveying mechanism 20 to the second conveying mechanism 30. By arranging the positioning piece 41 between the first conveying mechanism 20 and the second conveying mechanism 30 and arranging the axial direction of the third cylindrical surface 411 of the positioning piece 41 parallel to the axial direction of the second cylindrical surface 311, the film tape 50 will be turned when it contacts the third cylindrical surface 411, thus shortening the turning distance of the film tape 50. The film tape 50 can be turned in advance before it enters the second conveying mechanism 30, which ensures that the film tape 50 enters the second conveying mechanism 30 in the correct posture and avoids the film tape 50 being folded in the second conveying mechanism 30.
[0042] Referring to Figure 3In an embodiment, the positioning member 41 further comprises two limiting portions 412, which are respectively protruded on two ends of the third cylindrical surface 411, and are used to limit the film strip 50 in the width direction. By limiting the film strip 50 by the two limiting portions 412, the film strip 50 is prevented from being deviated or turned again before entering the second conveying mechanism 30, and the film strip 50 is further ensured to enter the second conveying mechanism 30 in the correct posture.
[0043] Continuing to refer to Figure 3 In an embodiment, the limiting portion 412 is provided with a circular arc surface 413 near one side of the third cylindrical surface 411, which is used to guide the film strip 50 to move towards the side near the third cylindrical surface 411. Specifically, the circular arc surface 413 can be a convex arc surface or a concave arc surface. When the film strip 50 is deviated during entering the positioning member 41 from the first conveying mechanism 20, the circular arc surface 413 is used to guide the film strip 50 to move towards the side near the third cylindrical surface 411, which can effectively correct the deviation of the film strip 50 and ensure that the deviated film strip 50 returns to the third cylindrical surface 411.
[0044] Referring to Figure 2 In an embodiment, the positioning mechanism 40 further comprises a mounting bracket 42, which is mounted on the first conveying mechanism 20 or the second conveying mechanism 30 and connected with the positioning member 41. By fixing the positioning member 41 between the first conveying mechanism 20 and the second conveying mechanism 30 through the mounting bracket 42, the original structure and layout of the film strip conveying device do not need to be greatly modified, and the cost is saved.
[0045] Optionally, in an embodiment, the mounting bracket 42 comprises a first adjusting shaft 421, a second adjusting shaft 422 and a third adjusting shaft 423. The first adjusting shaft 421 is used to adjust the position of the positioning member 41 in a first direction, the second adjusting shaft 422 is connected with the first adjusting shaft 421 and is used to adjust the position of the positioning member 41 in a second direction, and the third adjusting shaft 423 is connected with the second adjusting shaft 422 and the positioning member 41 and is used to adjust the position of the positioning member 41 in a third direction. The first direction, the second direction and the third direction are perpendicular to each other. Figure 1 and Figure 2 As shown in the figures, the first direction is the direction shown by the arrow S1, the second direction is the direction shown by the arrow S2, and the third direction is the direction shown by the arrow S3. By adjusting the position of the positioning member 41 by the first adjusting shaft 421, the second adjusting shaft 422 and the third adjusting shaft 423, the installation accuracy of the positioning member 41 is ensured, and the positioning member 41 is further ensured to be accurately turned before the film strip 50 enters the second conveying mechanism 30.
[0046] Referring to Figure 1In an embodiment, the first conveying mechanism 20 comprises a plurality of first transition pieces 21, such as two, three, four or more, which are arranged in the second direction at intervals to convey the film strip 50 in the second direction. By using the plurality of first transition pieces 21 to jointly convey the film strip 50 in the second direction, the stability and tension of the film strip 50 during the conveying process are improved.
[0047] In an embodiment, the first transition piece 21 comprises a transition shaft, and the first cylindrical surface 211 is located on the circumferential surface of the transition shaft. Specifically, the transition shaft extends in the first direction, and the film strip 50 is conveyed by using the first transition shaft, so that the film strip 50 can move in the axial direction of the transition shaft during the conveying process to adapt to different positions of the film strip 50 wound on the barrel 10, thereby avoiding the film strip 50 from being pulled and broken. Exemplarily, the axial direction of the barrel 10 is parallel to the axial direction of the transition shaft (i.e., the axial direction of the first cylindrical surface 211), thereby avoiding the film strip 50 from being turned during the process of entering the first conveying mechanism 20 from the barrel 10.
[0048] Continuing to refer to Figure 1 In an embodiment, the second conveying mechanism 30 comprises a plurality of second transition pieces 31, such as two, three, four or more, which are arranged in the first direction at intervals to convey the film strip 50 in the first direction. By using the plurality of first transition pieces 21 to jointly convey the film strip 50 in the second direction, the stability of the film strip 50 during the conveying process is improved. In combination with Figure 2 Preferably, the two adjacent second transition pieces 31 have a height difference in the second direction, thereby ensuring that the film strip 50 is kept tensioned during the conveying process in the first direction.
[0049] Referring to Figure 1 Exemplarily, the positioning piece 41 is arranged at intervals with the first second transition piece 31 in the plurality of second transition pieces 31 in the second direction, and in the second direction, the side of the positioning piece 41 in contact with the film strip is flush with the side of the first second transition piece 31 in contact with the film strip, thereby ensuring that the film strip 50 can enter the first second transition piece 31 straight after coming out of the positioning piece 41, further avoiding the film strip 50 from being folded when entering the second conveying mechanism 30.
[0050] Referring to Figure 1 The second transition piece 31 comprises a roller, and the second cylindrical surface 311 is located on the wheel surface of the roller. By conveying the film strip 50 by using the roller, the frictional loss of the film strip 50 can be reduced. Preferably, in combination with Figure 2 Preferably, the two ends of the second cylindrical surface 311 are convexly provided with blocking portions 312 for limiting the film strip 50 in the width direction of the film strip 50. By limiting the film strip 50 by using the two blocking portions 312, the film strip 50 is prevented from being deviated or falling off during the conveying process.
[0051] The application also provides a film pasting device, and one embodiment of the film pasting device comprises the film tape conveying device of any one of the above embodiments. The film tape 50 can be conveyed to a film pasting position smoothly by the film tape conveying device, so that the film pasting on the photovoltaic module is facilitated, and the power generation efficiency of the photovoltaic module after the film pasting is ensured.
[0052] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the present application.
[0053] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
