[0002] With the rapid development of renewable energy, flexible photovoltaics, as a new type of photovoltaic technology, has been widely applied in wearable devices, smart textiles, and building-integrated photovoltaics due to its numerous advantages such as flexibility, portability, malleability, high efficiency, and environmental friendliness. The emergence of flexible photovoltaic devices has brought breakthrough progress to traditional photovoltaic materials, especially in the power supply of mobile devices, electronic products, and low-power devices, showing broad application prospects.

[0003] Currently, the fabrication of flexible photovoltaic devices is mainly concentrated in laboratory environments, using spin coating or blade coating techniques. Traditional coating methods rely on manual or semi-automatic equipment, resulting in low production efficiency and unstable coating quality, leading to low yield and slow fabrication efficiency for high-performance, large-area modules.

[0004] By using automated production technology, high precision can be ensured while improving manufacturing efficiency and reducing errors caused by human intervention. This will help improve the overall performance and stability of flexible photovoltaic devices, while significantly reducing production costs and laying a solid foundation for the industrialization of flexible photovoltaics.

[0005] During the fabrication of flexible photovoltaic modules, the baseband gradually loosens during transmission, which in turn affects various processes in the manufacturing of flexible photovoltaic devices. Utility Model Content

The tension roller is sleeved on the outside of the first rotating shaft and is anti-rotatingly connected to the first rotating shaft. In use, the strip can be wrapped around the outside of the tension roller. When the rotary drive mechanism drives the eccentric connecting frame to rotate, due to the eccentric setting of the rotation axes of the first rotating shaft and the eccentric connecting frame, the first rotating shaft will drive the tension roller to swing, and the tension roller will tighten or loosen the strip to achieve the effect of adjusting the strip tension.

[0026] The following is combined Figure 1 This invention describes the tension adjustment device.

[0027] An embodiment of this utility model provides a tension adjustment device, including a rotary drive mechanism and an eccentric roller assembly.

[0028] The eccentric roller assembly may include an eccentric connecting frame, a first rotating shaft 110, and a tension roller 120. The eccentric connecting frame is connected to a rotary drive mechanism and is driven by the rotary drive mechanism to rotate around the rotation axis of the rotary drive mechanism. The first rotating shaft 110 is rotatably connected to the eccentric connecting frame, and its rotation axis is parallel to the rotation axis of the rotary drive mechanism and deviates from the rotation axis of the rotary drive mechanism by a certain distance. When the rotary drive mechanism drives the eccentric connecting frame to rotate, the first rotating shaft 110 connected to the eccentric connecting frame revolves around the rotation axis of the rotary drive mechanism.

[0029] The tension roller 120 is sleeved on the outside of the first rotating shaft 110 and is connected to the first rotating shaft 110 to prevent rotation, so that the tension roller 120 rotates synchronously with the first rotating shaft 110.

[0030] In use, the strip is moved around one side of the tension roller 120, and the rotary drive mechanism is started, which drives the eccentric connecting frame to rotate. The eccentric connecting frame drives the first rotating shaft 110 to rotate around the rotation axis of the rotary drive mechanism, thereby causing the tension roller 120 to tighten or loosen the strip, achieving the effect of strip tension adjustment.

[0031] In some embodiments, the eccentric connecting frame may include a first swing arm 131, which may be an elongated sheet-like structure. A connecting shaft 134 may be provided at one end of the first swing arm 131, near the side of the rotary drive mechanism. The connecting shaft 134 is perpendicular to the side of the first swing arm 131, and the end of the connecting shaft 134 away from the first swing arm 131 is connected to the rotary drive mechanism. The other end of the first swing arm 131 is provided with a first shaft hole, which is parallel to the axis of the connecting shaft 134. One end of a first rotating shaft 110 is rotatably connected to the first shaft hole, and the other end of the first rotating shaft 110 extends away from the rotary drive mechanism.

[0032] At this time, the rotation axis of the rotary drive mechanism, the rotation axis of the connecting shaft 134, and the rotation axis of the first rotating shaft 110 are parallel. When the rotary drive mechanism rotates, it drives the connecting shaft 134 to rotate, and the connecting shaft 134 drives the first swing arm 131 to rotate, so that the end of the first swing arm 131 with the first shaft hole swings around the axis, thereby driving the first rotating shaft 110 to swing around the axis, and finally achieving the effect of tension roller 120 tightening or loosening the strip.

[0033] In some embodiments, the eccentric connecting frame further includes a second swing arm 132, which is arranged parallel to the first swing arm 131 and is located on the side of the first swing arm 131 away from the rotary drive mechanism. The first swing arm 131 and the second swing arm 132 are a certain distance apart so that the first rotating shaft 110 can be installed between them.

[0034] The connecting shaft 134 extends towards the second swing arm 132 and eventually connects to the side of the second swing arm 132 closest to the first swing arm 131. After connection, the first swing arm 131 and the second swing arm 132 swing synchronously. The end of the second swing arm 132 away from the connecting shaft 134 is provided with a second shaft hole, and the axes of the first shaft hole and the second shaft hole are collinear.

[0035] The two ends of the first rotating shaft 110 are rotatably connected to the first shaft hole of the first swing arm 131 and the second shaft hole of the second swing arm 132, respectively. After connection, the first rotating shaft 110, the connecting shaft 134, the first swing arm 131 and the second swing arm 132 form a rectangular structure.

[0036] Thus, both ends of the first rotating shaft 110 are effectively supported. Compared with the previous embodiment, where the first rotating shaft 110 is supported only by the first swing arm 131, this embodiment provides more stable support for the first rotating shaft 110, making its operation more stable.

[0037] In some embodiments, an extension arm 133 is provided on both the first swing arm 131 and the second swing arm 132. The extension arm 133 extends radially away from the first rotating shaft 110. A third shaft hole is provided at the end of the extension arm 133 away from the first rotating shaft 110. The axes of the third shaft holes of the two extension arms 133 are collinear. A second rotating shaft 141 is rotatably inserted between the two third shaft holes. A support roller 142 is sleeved on the second rotating shaft 141, and the support roller 142 is anti-rotationally connected to the second rotating shaft 141.

[0038] At this time, the first rotating shaft 110, the second rotating shaft 141, the connecting shaft 134, the first swing arm 131, the second swing arm 132, and the extension arm 133 form a U-shaped structure. When the strip is slack, such as during strip installation, the idler roller 142 can temporarily support the slack strip to prevent the strip from coming into contact with other items and getting dusty.

[0039] In some embodiments, the connecting shaft 134 and the power output shaft of the rotary drive mechanism can be connected by a coupling 200, a gear transmission mechanism, a belt transmission mechanism, or a chain transmission mechanism, etc. (The appendix of this utility model...) Figure 1 The coupling used is 200.

[0040] In some embodiments, the rotary drive mechanism may include a frame, a drive shaft 330, a third swing arm 340, and a linear telescopic device 350.

[0041] The frame can be a mounting plate 310, which has a fourth shaft hole. A bearing assembly 320 is mounted on one side of the mounting plate 310, with the axis of the bearing assembly 320 collinear with the fourth shaft hole. A drive shaft 330 passes through the bearing assembly 320. On the side of the mounting plate 310 away from the bearing assembly 320, one end of the third swing arm 340 is anti-rotationally connected to the end of the drive shaft 330, for example, by a key connection. A linear telescopic device 350 is located on the side of the mounting plate 310 away from the bearing assembly 320. The other end of the third swing arm 340 is rotatably connected to the telescopic end of the linear telescopic device 350, with the axis of rotation parallel to the axis of the drive shaft 330. The fixing part of the linear telescopic device 350 is rotatably connected to the mounting plate 310, with the axis of rotation parallel to the axis of the drive shaft 330.

[0042] When the linear telescopic device 350 extends or retracts, it can drive the third swing arm 340 to swing, which in turn drives the drive shaft 330 to rotate, converting the linear motion of the linear telescopic device 350 into rotational motion.

[0043] The linear telescopic device 350 can be a cylinder or an electric actuator, etc.

[0044] In some embodiments, the rotary drive mechanism may also be a rotary motor, with the power output end of the rotary motor directly connected to the connecting shaft 134 for transmission.

[0045] The embodiments of this utility model also provide a strip processing equipment, such as a flexible photovoltaic base strip processing equipment. Since it is equipped with the tension adjustment device as described above, it has the same advantages as described above, which will not be repeated here.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and they should all be covered within the scope of the claims and specification of this application.
