Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic module assembly equipment technology, and in particular to a smoothing device. Background Technology
[0002] Currently, solar photovoltaic modules are widely used. The glass surface of solar photovoltaic panels is covered with an encapsulating film, namely PO (polyolefin) film. During assembly, due to the large area of the PO film, air bubbles may be generated when it is placed on the glass. These air bubbles between the PO film and the glass can cause wrinkles during hot-press sealing, resulting in poor adhesion between the PO film and the glass. This directly affects the light transmittance and lifespan of the solar photovoltaic module.
[0003] Existing technologies employ two designs for air bubble smoothing mechanisms. The first is a roller-type design, which uses a roller-contact smoothing method when smoothing the PO film. This method can cause displacement and misalignment of the PO film due to excessively tight contact. The second design uses a scraper-type design, with a straight scraper that directly smooths the film from the center outwards. However, there is no air venting design during the smoothing process, resulting in poor smoothing effect and a risk of film cracking.

[0039] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication of two components. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.
[0040] The following describes in further detail a smoothing device provided in this embodiment with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.
[0041] Please refer to Figure 1 This application provides a smoothing device for photovoltaic modules, including: an exhaust mechanism 1 and a smoothing mechanism 2; the exhaust mechanism 1 is disposed above the middle position in the width direction of the adhesive film 0 and includes an elastic exhaust pad 11 that can be raised and lowered relative to the adhesive film 0 to contact or separate from the adhesive film 0; the smoothing mechanism 2 includes a first smoothing mechanism 21 and a second smoothing mechanism 22 respectively disposed on both sides of the exhaust mechanism in the width direction of the adhesive film 0, the first smoothing mechanism 21 and the second smoothing mechanism 22 can be raised and lowered relative to the adhesive film 0 to contact or separate from the adhesive film 0, and after descending to contact the adhesive film 0, they can move along the width direction of the adhesive film from the exhaust mechanism 1 to the edge of the adhesive film.
[0042] Specifically, such as Figure 1As shown, the venting mechanism 1 includes a sponge venting pad 11, which is used to contact the adhesive film 0 and flatten air bubbles under the adhesive film 0. The adhesive film 0 is a PO film. After the PO film is laid on the glass, the venting mechanism 1 of the smoothing device presses down on the middle of the PO film. After pressing down and contacting the PO film, the sponge venting pad 11 performs its flattening and venting function. The sponge venting pad 11 can be a high-density sponge pad, which is designed with built-in cushioning. While protecting the glass and the PO film, it can also expel air between the PO film and the glass surface. After the venting mechanism 1 presses down on the PO film to complete the venting action, the smoothing mechanism 2, through a first smoothing mechanism 21 and a second smoothing mechanism 22 respectively located on both sides of the venting mechanism 1, smooths the film from the middle to both ends. The first smoothing mechanism 21 moves towards the first side of the venting mechanism 1 and smooths the adhesive film 0 located on the first side of the venting mechanism 1, and the second smoothing mechanism 22 moves towards the second side of the venting mechanism 1 and smooths the adhesive film 0 located on the second side of the venting mechanism 1. When the leveling mechanism 2 moves to level the adhesive film 0, the venting mechanism 1 positions the adhesive film 0 to prevent it from shifting relative to the glass during the movement of the leveling mechanism 2. For example, the first side is the left side, and the second side is the right side.
[0043] The smoothing device provided in the embodiments of this application contacts the adhesive film 0 with the sponge venting pad 11 and flattens the air bubbles under the adhesive film 0. Then, the first smoothing mechanism 21 and the second smoothing mechanism 22 respectively set on both sides of the venting mechanism 1 smooth the adhesive film 0 from the middle to both sides. It has high smoothing efficiency and good venting effect, and the adhesive film 0 is not easy to shift. It solves the problem of misalignment of battery string placement and cracking caused by the current adhesive film 0 bulging phenomenon.

Multiple leveling buffer devices 202 are arranged along the length of the adhesive film 0 to provide uniform support to the scraper 201 along the length of the adhesive film 0. The leveling support device 203 connects multiple leveling buffer devices 202 to the leveling lifting device 204. The leveling support device 203 has a certain length along the length of the adhesive film 0, allowing the multiple leveling buffer devices 202 arranged along the length of the adhesive film 0 to be fixed to the leveling support device 203. The leveling lifting device 204 drives the scraper 201 to move up and down, and the translation device 205 drives the scraper 201 to move horizontally. The leveling buffer devices 202 act as buffers during the up and down movement and horizontal movement of the scraper 201, which is beneficial for the scraper 201 to level the adhesive film 0.
[0046] In the embodiments of this application, the scraper 201 is driven to move by the scraper lifting device 204 and the translation device 205. The scraper buffer device 202 buffers the scraper, making the movement of the scraper 201 more stable, the scraping effect better and less prone to displacement.

For example... Figure 4As shown, each first buffer post 2021 is vertically arranged and its bottom end is fixedly connected to the scraper 201. The first buffer fixing frame 2023 includes a vertically arranged first vertical plate and a horizontally arranged first horizontal plate. The lower end of the first vertical plate is fixedly connected to the first horizontal plate. For example, the first buffer fixing frame 2023 is "L" shaped. The first vertical plate of the first buffer fixing frame 2023 is fixedly connected to the scraping bearing device 203. The first horizontal plate of the first buffer fixing frame 2023 is provided with a first through hole.
