Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel production equipment processing high-temperature cloth components, in particular to a mechanism for grabbing the high-temperature cloth. Background Art

[0002] In the production process of photovoltaic panels, high temperature cloth is used mainly for the needs of lamination process. Lamination is to encapsulate photovoltaic cells between glass and back sheet, and form a sealed structure by high temperature and pressure to protect the cells and improve the durability and efficiency of the components. The structure of high temperature cloth on photovoltaic panels is as follows: Figure 7 As shown, there is a threading hole in the middle of the photovoltaic panel for the lead wire to pass through, and then the lead wire stands up. There are two holes on the high-temperature cloth for the upright lead wire to pass through. Glue is injected into the holes of the photovoltaic panel, and the excess glue sticks the high-temperature cloth to the photovoltaic panel. The high-temperature cloth (usually made of Teflon or other high-temperature resistant materials) plays the following key roles in this process:

[0003] 1. Prevent adhesion: High temperature cloth has excellent non-stick properties, which can ensure that packaging materials such as EVA (ethylene-vinyl acetate copolymer) will not adhere to the hot pressing plate of the laminator during the lamination process, facilitating subsequent peeling operations.

[0004] 2. Provide flatness: High temperature cloth helps to keep the material flat during lamination, avoid bubbles or wrinkles, and ensure the optical and electrical properties of the components.

[0005] 3. High temperature resistance: During the high temperature lamination process, the high temperature cloth can withstand high temperatures without deformation or damage, and maintain its physical properties stable.

[0006] However, after lamination is completed, the high temperature cloth needs to be removed from the photovoltaic panel for the following reasons: completion of encapsulation, removing the high temperature cloth means the end of the lamination process, the battery module has been fully encapsulated, and no additional protection or isolation is required; aesthetics and efficiency, the high temperature cloth itself is not part of the photovoltaic module, and leaving it on the module will affect the transmittance, thereby reducing the power generation efficiency and may affect the appearance; electrical safety, residual high temperature cloth fragments or fibers may cause short circuit risks and affect the safe operation of photovoltaic modules; quality inspection and certification, in order to pass relevant product quality standards and certifications (such as IEC 61215, etc.), it is necessary to ensure that the surface of the module is clean and free of foreign matter. Therefore, removing the high temperature cloth is a necessary step to ensure the performance, safety and compliance of photovoltaic modules with industry standards.

[0007] The existing equipment for grabbing high temperature cloth has the following disadvantages:

[0008] Poor flexibility: The equipment with frame structure and motor guide rail movement and positioning may have poor adaptability and flexibility, and it is difficult to cope with complex fabric layout tasks. The structure is relatively complex and the cost is high.

[0009] High maintenance costs: The maintenance and upkeep of components such as motor rails may be cumbersome and require regular inspection and maintenance, increasing management costs and workload.

[0010] Low degree of automation: The equipment for the moving and positioning of the rack structure and motor guide rails has a low degree of automation, which may require more manpower to operate and monitor, resulting in lower production efficiency of photovoltaic panels.

[0011] Therefore, there is an urgent need to design a mechanism for grabbing the high-temperature cloth to solve the problems of poor flexibility, low degree of automation and high maintenance cost of the existing mechanism for grabbing the high-temperature cloth. Utility Model Content

[0014] Specifically, the scraper cylinder adopts a double-rod double-output shaft type cylinder, and the scraper cylinder is installed on the cylinder mounting seat by bolts.

[0016] Specifically, the vertical height of the installation groove is greater than the thickness of the scraper plate, and the scraper plate has a movable range for rotating up and down in the installation groove through the pin shaft.

[0017] Specifically, the side surface of the cylinder mounting seat is a "T"-shaped structure, and four clamping protrusions are arranged at the bottom of the cylinder mounting seat.
