Description

Technical Field

[0001] This utility model relates to the field of optical component manufacturing technology, and in particular to a device for removing residual EVA waste after edge trimming of photovoltaic modules. Background Technology

[0002] In the production process of photovoltaic modules, encapsulating films are usually used, such as EVA waste, POE film, and EPE film, to arrange and laminate glass, solar cells, backsheet or back glass in sequence. In order to avoid air bubbles after lamination due to insufficient film, the film size is usually larger than the glass. After lamination, there will be residual film at the edge of the module. It is usually trimmed by an edge trimming machine. After trimming, the module is then assembled into a frame and other further processing steps.

[0003] The existing edge trimming machine has two cylinder tail material clamps inside, which are activated by photoelectric signals to remove tail material during the module operation. However, in order to avoid interference with the module, the single cylinder tail material clamp is usually kept at a certain distance from the module, which results in EVA waste at the four corners of the module not being completely removed. If it is not removed, there will be poor glue overflow at the corners after framing. Therefore, the operator needs to remove it manually, which slows down the cycle of photovoltaic modules. Utility Model Content

[0004] The purpose of this invention is to provide a device for removing residual EVA waste after edge trimming of photovoltaic modules, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a device for removing residual EVA waste after edge trimming of photovoltaic modules, including a support base, on which two rotary motors are symmetrically arranged, the two rotary motors being arranged at a 90° angle, and a telescopic cylinder is provided at the output end of the rotary motor, the output end of the telescopic cylinder being connected to a scraper.

[0006] Preferably, four removal devices are provided, which are located inside the edge trimming machine and distributed around the photovoltaic module.

[0007] Preferably, the scraper is connected to the output end of the telescopic cylinder via a universal joint.

[0008] Preferably, a lifting cylinder is provided at the bottom of the support base.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The present invention provides a device for removing residual EVA waste after edge trimming of photovoltaic modules. The device has four parts distributed around the photovoltaic module. When it is necessary to remove EVA waste from the edge of the photovoltaic module, two rotary motors rotate synchronously, driving the scraper to move along the edge of the photovoltaic module, thereby scraping off the EVA waste. During the scraping process, the telescopic cylinder drives the scraper to retract, so that the scraper always keeps in contact with the edge of the photovoltaic module. At the same time, the scraper uses a universal joint to rotate adaptively, thereby more effectively scraping off the EVA waste. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Figure 1 This is a schematic diagram of a device for removing residual EVA waste after edge trimming of photovoltaic modules, provided as an embodiment of the present invention. Figure 1 As shown, the embodiment of this utility model provides a device for removing residual EVA waste after edge trimming of photovoltaic modules. The device for removing residual EVA waste after edge trimming of photovoltaic modules may include a support base 1, on which two rotary motors 2 are symmetrically arranged, the two rotary motors 2 are arranged at a 90° angle, and the output end of the rotary motor 2 is provided with a telescopic cylinder 3, and the output end of the telescopic cylinder 3 is connected to a scraper 4.

[0015] With the above technical solution, when it is necessary to remove EVA waste from the edge of the photovoltaic module, two rotary motors 2 rotate synchronously, driving the scraper 4 to move along the edge of the photovoltaic module. The two scrapers 4 meet at the corner, thereby scraping off the EVA waste. This eliminates the need for manual removal by operators, improving production efficiency. During the scraping process, the telescopic cylinder 3 drives the scraper 4 to retract, ensuring that the scraper 4 always remains in contact with the edge of the photovoltaic module, thus scraping off the EVA waste more thoroughly.

[0016] In one embodiment of this invention, four devices are provided for removing residual EVA waste after edge trimming of the photovoltaic module. These four devices are located inside the edge trimming machine and distributed around the photovoltaic module. The four devices operate simultaneously, scraping away the residual EVA waste from all four edges of the photovoltaic module, thereby completely removing the residual EVA waste from the photovoltaic module.

[0017] In one embodiment of this invention, the scraper 4 is connected to the output end of the telescopic cylinder 3 via a universal joint. During the scraping process, the scraper 4 utilizes the adaptive rotation of the universal joint to more closely adhere to the edge of the photovoltaic module, thereby more effectively scraping away EVA waste.

[0018] In one embodiment of this utility model, a lifting cylinder is provided at the bottom of the support base 1. The lifting cylinder allows the support base 1 to move up and down, ensuring that the scraper 4 is vertically aligned with the edge of the photovoltaic module.

[0019] In practical applications, the working principle of the device for removing residual EVA waste after edge trimming of photovoltaic modules provided by this utility model is as follows:

[0020] During operation, the device for removing residual EVA waste after edge trimming of the photovoltaic module is equipped with four units distributed around the photovoltaic module. When it is necessary to remove EVA waste from the edge of the photovoltaic module, the support base 1 is moved up and down by the lifting cylinder, so that the scraper 4 is vertically facing the edge of the photovoltaic module. The two rotary motors 2 rotate synchronously, driving the scraper 4 to move along the edge of the photovoltaic module. At the corner, the two scrapers 4 meet, thereby scraping off the EVA waste. No manual removal by the operator is required, improving production efficiency. During the scraping process, the telescopic cylinder 3 drives the scraper 4 to retract, so that the scraper 4 always keeps in contact with the edge of the photovoltaic module. At the same time, the scraper 4 uses the universal joint to adapt to the rotation, so that it can fit more closely to the edge of the photovoltaic module, thereby more effectively scraping off the EVA waste.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
