Description

Technical Field

[0001] This utility model relates to the field of photovoltaic device manufacturing technology, and in particular to a strip driving device and strip processing equipment. Background Technology

[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-automated 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] However, in the process of manufacturing flexible photovoltaic modules, the baseband transmission distance is too long, and it is difficult to complete the baseband transmission throughout the entire production line by relying solely on the power provided by the winding and unwinding rollers.

[0023] The strip driving device provided by this utility model includes a drive roller assembly and a clamping roller assembly. The drive roller assembly includes a first support, a rotary drive mechanism, a drive shaft, and drive rollers. Both the rotary drive mechanism and the drive shaft are connected to the first support. The drive shaft is drively connected to the rotary drive mechanism. The drive rollers are sleeved on the drive shaft and are anti-rotatingly connected to the drive shaft. The clamping roller assembly includes a second support, a linear drive mechanism, a driven shaft, and a driven roller. The fixed part of the linear drive mechanism is connected to the first support, and the moving part of the linear drive mechanism is connected to the second support.

The driven shaft is rotatably connected to the second support, and is arranged parallel to the drive shaft, located on the side of the second support closer to the drive shaft. The driven rollers are sleeved on the outside of the driven shaft and are anti-rotatingly connected to the driven shaft. In use, the strip is passed through the gap between the drive roller and the driven roller. Then, the linear drive mechanism drives the second support to move radially toward the drive shaft. The driven shaft and driven roller move synchronously with the second support, thereby clamping the strip between the drive roller and the driven roller. When the rotary drive mechanism drives the drive shaft to rotate, the drive roller drives the strip to move in the transmission direction under the action of friction, providing power for the transmission of the strip. The strip drive device provided by this utility model provides auxiliary power for long-distance strip transmission, realizing long-distance strip conveying.

[0024] The following is combined Figure 1 This invention describes a strip drive device and a strip processing equipment.

[0025] An embodiment of this utility model provides a strip driving device, including a drive roller group and a clamping roller group. The strip is clamped between the drive roller group and the clamping roller group to increase the friction between the strip and the drive roller group. When the drive roller group rotates, the strip is driven to move by the friction.

[0026] The drive roller assembly includes a first support 110, a rotary drive mechanism, a drive shaft, and a drive roller 160.

[0027] Specifically, such as Figure 1 As shown, the first bracket 110 can be a mounting plate, and the rotation drive mechanism can be a drive motor 120. The drive motor 120 can be detachably fixed to the right side of the mounting plate via the mounting column 130. The power output axis of the drive motor 120 extends to the left and is perpendicular to the right side of the mounting plate.

[0028] A bushing 140 and a mounting base 150 are provided on the mounting plate. The bushing 140 is fixed to the mounting plate by the mounting base 150. The drive shaft is rotatably connected to the mounting plate through the bushing 140. On the right side of the mounting plate, the drive shaft is connected to the power output shaft of the drive motor 120. The left side of the drive shaft extends to the left side of the mounting plate.

[0029] The drive roller 160 is sleeved on the outside of the portion of the drive shaft located on the left side of the mounting plate and is anti-rotationally connected to the drive shaft. For example, the drive roller 160 and the drive shaft can be connected by a key.

[0030] Thus, when the drive motor 120 rotates, it can drive the drive roller 160 to rotate synchronously through the drive shaft.

[0031] Of course, the drive motor 120 described above is only an example of a rotary drive mechanism. The rotary drive mechanism can also be a pneumatic rotary mechanism, etc.

[0032] The clamping roller assembly may include a second support 210, a linear drive mechanism, a driven shaft, and a driven roller 230.

[0033] For details, please refer to Figure 1 The second bracket 210 may include a mounting rod, a sliding rod, and a support rod. The mounting rod and the sliding rod may be set vertically, with one end of the sliding rod connected to one end of the mounting rod. The support rod is inclined and supported at the two ends of the mounting rod and the sliding rod that are far apart from each other. At this time, the mounting rod, the sliding rod, and the support rod form a triangular structure.

[0034] Two support arms can be installed on the side of the mounting rod away from the sliding rod. Bearings can be installed at the ends of the support arms away from the mounting rod. The two bearings are coaxial, and their axes are parallel to the extension direction of the mounting rod. The two ends of the driven shaft are connected to the two bearings respectively to achieve a rotational connection between the driven shaft and the mounting rod.

[0035] The driven roller 230 is sleeved on the outside of the driven shaft and is connected to the driven shaft to prevent rotation. For example, the driven shaft and the driven roller 230 can be connected by a key so that the driven roller 230 rotates synchronously with the driven shaft.

[0036] A slide rail assembly 240 is provided between the side of the sliding rod away from the mounting rod and the side of the mounting plate away from the drive motor 120, and the sliding direction of the slide rail assembly 240 is along the radial direction of the drive shaft.

[0037] For example, the second bracket 210 is located below the drive shaft, and the sliding direction of the slide rail assembly 240 is along the vertical direction.

[0038] The linear drive mechanism can be a linear push rod 220. The fixed part of the linear push rod 220 is fixedly connected to the mounting plate, and the moving part of the linear push rod 220 is connected to the mounting rod or sliding rod of the second bracket 210. When the linear push rod 220 extends, it drives the driven roller 230 to move radially toward the drive roller 160 along the drive shaft through the second bracket 210. When the linear push rod 220 retracts, it drives the driven roller 230 to move radially away from the drive roller 160 along the drive shaft through the second bracket 210, so as to achieve clamping or loosening of the strip.

[0039] Of course, the linear drive mechanism can also be a cylinder or other linear telescopic mechanism.

[0040] In use, the driven roller 230 is driven by a linear drive mechanism to move away from the drive roller 160, and then the strip passes through the space between the drive roller 160 and the driven roller 230. Then, the driven roller 230 is driven by the linear drive mechanism to move closer to the drive roller 160, applying a preload to the strip so that there is a certain static friction between the strip and the drive roller 160.

[0041] After installation, start the rotary drive mechanism. The rotary drive mechanism drives the drive roller 160 to rotate, and under the action of friction, it drives the strip to move in the transmission direction, providing power for the strip to move in the transmission direction.

[0042] The strip driving device provided by this utility model can provide auxiliary driving force for long-distance conveying of strips, enabling the strips to achieve the effect of long-distance conveying.

[0043] In some embodiments, the rotary drive mechanism and the drive shaft can be connected by a coupling, gear transmission mechanism, belt transmission mechanism or chain transmission mechanism.

[0044] In some embodiments, a flexible friction liner is applied to the outer side of the drive roller 160 or the driven roller 230, or both the drive roller 160 and the driven roller 230 are applied to the outer side. The flexible friction liner prevents the rigid drive roller 160 or driven roller 230 from scratching the strip during transport, and also increases the friction between the drive roller 160, driven roller 230, and the strip, preventing slippage.

[0045] For example, the flexible friction liner can be made of rubber or polyurethane.

[0046] 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 strip driving device described above, it has the same advantages as described above, which will not be repeated here.

[0047] 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. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
