Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel glass removal, in particular to a stripping type glass removal device. Background Art

[0002] With the continuous reduction of the average photovoltaic power generation cost, the installed capacity of photovoltaic modules has increased year by year, and the domestic solar energy application has formed a clustering scale effect. As the photovoltaic modules invested in the early stage have reached the end of their service life, a large number of photovoltaic modules are facing retirement, and more and more discarded photovoltaic panels will be generated. The scrapped photovoltaic panels contain renewable raw materials such as aluminum profiles, glass, rubber, copper, and silicon, which are of great significance to the green recycling of resources. At present, the recycling and reuse of photovoltaic panels is to remove the plastic box, aluminum frame, and glass from the photovoltaic panels, and then coarsely crush, finely crush, and grind them for sorting.

[0003] Among them, photovoltaic panel deglazing is a key link, which is related to the recycling and subsequent processes of glass. Conventional methods include milling deglazing and self-extrusion deglazing. Among them, milling deglazing has a complex structure and the milling cutter is inconvenient to replace. Self-extrusion deglazing has the problem of unclean removal and the head and tail residues cannot be processed, resulting in incomplete glass removal. Therefore, this technical solution is proposed for improvement. Utility Model Content

DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0019] See also Figures 1 to 5The utility model discloses a stripping type glass removal device, which is mainly used in the glass stripping process in the production process of photovoltaic panels. It mainly includes a frame 1, which is used to fix and support the entire device. A collecting trough 5 is installed inside the frame 1 to collect the peeled glass. A conveyor belt or a drawer can be installed below the collecting trough 5 to collect the peeled glass in a centralized manner, which is convenient for subsequent processing.

[0020] A mounting frame is provided on the upper part of the frame 1, and a front conveying device 2 and a rear conveying device 3 are provided on the left and right ends of the mounting frame. The front conveying device 2 and the rear conveying device 3 are respectively located on the front and rear sides of the photovoltaic panel for stable transportation of the photovoltaic panel. The front conveying device 2 and the rear conveying device 3 both include an upper pressure roller 201 and a lower pressure roller 202, which rotate synchronously through a synchronous belt to ensure the stability of the photovoltaic panel during transportation. At the same time, the front conveying device 2 and the rear conveying device 3 are driven by a feeding motor 301 to realize automatic transportation of the photovoltaic panel. During use, the upper pressure roller 201 and the lower pressure roller 202 of the front conveying device 2 transport the photovoltaic panel to the inside. During the transportation, the glass faces downward, and the upper pressure roller 201 and the lower pressure roller 202 squeeze the glass on the photovoltaic panel to break the whole piece of glass into small pieces to reduce the adhesion of the glass. In this process, some glass will fall off from the photovoltaic panel, and the fallen glass will be transferred to the collection tank 5 for collection. The glass adhering to the photovoltaic panel will continue to be transported backwards and continue production.

[0021] A knife holder 702 is provided on the conveying path of the front conveying device 2. The length of the knife holder 702 is greater than the width of the photovoltaic panel, ensuring that the entire glass surface of the photovoltaic panel can be effectively contacted by the scraper 7 during the conveying process. A limiting channel 6 is installed on the travel path of the photovoltaic panel. When the photovoltaic panel moves to the left, both ends of the photovoltaic panel are stuck in the limiting channel 6, ensuring the continuity of production and the controllability of the direction of movement of the photovoltaic panel.

[0022] The specific structure of the knife frame 702 includes a fixed frame, a guide rail is installed horizontally on the upper part of the fixed frame, a knife disc 701 is slidably arranged on the guide rail through a slider, and a scraper 7 is arranged on the upper surface of the knife disc 701. The scraper 7 is connected to the knife disc 701 by screw connection and is equidistantly arranged. There is a gap between two adjacent scrapers 7, and the scraper 7 has a certain thickness to ensure structural strength, ensure that the scraper 7 can be evenly stressed when scraping the glass, and improve the peeling effect. In order to drive the knife disc 701 to slide on the guide rail, the knife disc 701 is connected to the driving device 704 through a connecting rod 703, and the output end of the connecting rod 703 and the driving device 704 is connected through an eccentric shaft 705. Next, the driving device 704 is a motor. When the driving device 704 is working, the eccentric shaft 705 rotates to drive the connecting rod 703 to drive the cutter disc 701 to slide back and forth on the guide rail. Since the glass on the photovoltaic panel has been broken into small pieces, the scraper 7 abuts against the glass during the movement of the photovoltaic panel. Driven by the driving device 704, the scraper 7 moves laterally along the width direction of the photovoltaic panel. Multiple scrapers 7 simultaneously perform glass movements on the photovoltaic panel to scrape the glass surface of the photovoltaic panel. Since the length of the cutter disc 701 and the scraper 7 is relatively long, the photovoltaic panel can be scraped in all directions, which greatly improves the removal effect, reduces the glass residue at the head and tail of the material, and ensures the use effect.

[0023] A steel brush 401 is rotatably arranged between the tool holder 702 and the rear conveying device 3. The steel brush 401 is in the shape of a roller. A pressure plate 4 that can be adjusted up and down is arranged above the steel brush 401. The pressure plate 4 can be adjusted up and down by bolts to adapt to photovoltaic panels of different thicknesses. After the photovoltaic panel passes through the tool holder 702 for glass stripping, it enters between the steel brush 401 and the pressure plate 4. The steel brush 401 further cleans the stripped photovoltaic panel to remove residual glass fragments and impurities, thereby improving the quality of subsequent processing.

[0024] In actual use, the photovoltaic panel is first placed on the front conveying device 2, and the feeding motor 301 is started. The photovoltaic panel is conveyed to the top of the tool holder 702 through the synchronous rotation of the front conveying device 2 and the rear conveying device 3. Then the driving device 704 is started to drive the knife disc 701 to slide back and forth on the guide rail, and the glass surface of the photovoltaic panel is scraped by the scraper 7. The peeled photovoltaic panel continues to be conveyed backward, and is cleaned by the steel brush 401 and the pressing plate 4, and finally output to the subsequent process. It has a simple structure and is easy to operate. It can realize the effective peeling and cleaning of the glass surface of the photovoltaic panel, thereby improving the production efficiency and quality of the photovoltaic panel.
