Description

Technical Field

[0001] This utility model relates to the field of photovoltaic manufacturing technology, and in particular to a perovskite glass edge sealing welding device. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Existing rigid perovskite thin-film solar cells, after undergoing laser scribing and edge cleaning processes, are sealed with butyl rubber around the glass, filled with POE film inside, and then laminated with a cover plate to obtain the module.

[0004] Because perovskite materials are sensitive to water and oxygen environments, they are basically completely oxidized and decomposed after being placed in the air for about 24 hours. Traditional butyl rubber has a certain water and oxygen permeability, which increases after aging, affecting the stability of the perovskite layer interface and leading to a decrease in conversion rate. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a perovskite glass edge-sealing welding device, thereby improving the service life of components after glass edge sealing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a perovskite glass edge sealing welding device, comprising: A stage for supporting glass sheets to be welded; A rotating mechanism, the output end of which is connected to the stage; A pressing mechanism, which can be raised and lowered, is located above the platform to press the glass sheet to be welded onto the platform; A welding mechanism, located on one side of the platform, is used to weld the glass sheet to be welded; Heating mechanism, used to heat the glass sheet to be welded.

[0007] Furthermore, the heating mechanism is located on the platform to heat the glass sheet to be welded.

[0008] Furthermore, the heating mechanism is located on the pressing mechanism to heat the glass sheet to be welded.

[0009] Furthermore, the heating mechanism consists of multiple heating wires.

[0010] Furthermore, the plurality of heating wires are arranged along the plurality of welding edges of the glass to be welded and are matched with the welding trajectory.

[0011] Furthermore, silicone strips are provided on the opposite side of both the pressing mechanism and the platform.

[0012] Furthermore, it also includes a limiting mechanism, which is disposed on the platform and is used to clamp the glass sheet to be welded diagonally on the platform.

[0013] Furthermore, the pressing mechanism includes a lifting component and an upper pressure plate rotatably disposed at the output end of the lifting component. The upper pressure plate is used to be driven to rotate by the loading platform after pressing the glass sheet to be welded.

[0014] Furthermore, the pressing mechanism includes a lifting component, an upper pressure plate rotatably disposed at the output end of the lifting component, and a driving component for actively rotating the upper pressure plate. The driving component is used to drive the upper pressure plate to rotate synchronously with the stage after the upper pressure plate presses the glass sheet to be welded.

[0015] Furthermore, the pressing mechanism also includes a pressure sensor to detect the downward pressure exerted by the upper pressure plate on the glass sheet to be welded.

[0016] The beneficial effects of this utility model are reflected in: This invention places the glass sheet to be welded on a platform and presses it down on the platform using a pressing mechanism to fix it in place. Then, a welding mechanism is used to weld and seal the glass sheet. After welding one side is completed, a rotating mechanism drives the platform to rotate, adjusting the welding point of the glass sheet so that the welding mechanism can continue to weld the remaining points. Because the glass edge sealing adopts a welding edge sealing method, the service life of the component after glass edge sealing can be improved. At the same time, the heating mechanism is used during the welding process to delay the cooling time, making the molten pool more stable and eliminating some glass stress, resulting in a good welding effect.

[0019] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figure 1-3 This utility model discloses a perovskite glass edge sealing welding device, comprising: Stage 1, used to support the glass sheet to be welded; Rotation mechanism 2, the output end of which is connected to stage 1; The pressing mechanism 3 is raised and lowered above the platform 1 to press the glass sheet to be welded onto the platform 1. The welding mechanism is located on one side of the stage 1 and is used to weld the glass sheet to be welded. Heating mechanism, used to heat the glass sheet to be welded.

[0021] In this invention, the glass sheet to be welded is placed on the stage 1, and the pressing mechanism 3 presses the glass sheet to be welded onto the stage 1 to fix it. Then, the welding mechanism welds and seals the glass sheet. After one side is welded, the rotating mechanism 2 drives the stage 1 to rotate, adjusting the welding point of the glass sheet to be welded, so that the welding mechanism can continue to weld the remaining welding points. Because the glass edge sealing adopts the welding edge sealing method, the service life of the component after glass edge sealing can be improved. At the same time, because the heating mechanism is used to delay the cooling time during the welding process, the molten pool is more stable and some glass stress is eliminated, resulting in a good welding effect.

[0022] In one embodiment, the heating mechanism is disposed on the stage 1 and heats the glass sheet to be welded uniformly from below; in another embodiment, the heating mechanism is disposed on the pressing mechanism 3 and heats the glass sheet to be welded uniformly from above; in yet another embodiment, the heating mechanism is disposed on both the stage 1 and the pressing mechanism 3, and heats both the upper and lower sides of the glass sheet to be welded simultaneously. Heating by any of the above heating methods can delay the cooling time, make the molten pool more stable, and eliminate some glass stress, thereby achieving a better welding effect. Furthermore, since the heating mechanism can be adjusted according to specific processing requirements, it can also meet different processing scenarios.

[0023] Furthermore, to meet the processing requirements of glass with different shapes, the heating mechanism consists of multiple heating wires. The heating wires can be flexibly adjusted in position according to the shape of the glass, arranged along the edge of the glass to be welded and matched with the welding trajectory to ensure a stable temperature field in the welding area. Specifically, both the stage 1 and the pressing mechanism 3 are provided with mounting holes for installing the heating wires. The shape and installation position of the mounting holes are not specifically limited, as long as they meet the heating requirements of the glass sheet to be welded.

[0024] In one embodiment, silicone strips 4 are provided on opposite sides of the pressing mechanism 3 and the stage 1. The function of the silicone strips 4 is to reduce damage to the glass during the pressing process and increase the friction of the contact surface to prevent the glass from shifting during fixing. Specifically, the shape and installation position of the silicone strips 4 are not specifically limited, as long as they meet the fixing requirements of the glass sheet to be welded.

[0025] Furthermore, silicone strip 4 can be replaced with a rubber strip that has the same high-temperature resistance and elasticity.

[0026] In one embodiment, a limiting mechanism 5 is also provided on the stage 1, which clamps the glass sheet to be welded diagonally on the stage 1.

[0027] This design allows the pressing mechanism 3 to be diagonally positioned by the limiting mechanism 5 before pressing down, ensuring that the glass sheet to be welded will not shift or shake during the pressing process, thus improving the subsequent welding quality.

[0028] Specifically, the limiting mechanism 5 includes an L-shaped diagonal fixing plate disposed at one corner of the platform 1 and a pressure component that pushes the glass on the platform 1 toward the L-shaped diagonal fixing plate. The pressure component is not specifically limited, as long as it can push the glass toward the L-shaped diagonal fixing plate.

[0029] In one embodiment, the pressing mechanism 3 includes a lifting component and an upper pressure plate rotatably disposed at the output end of the lifting component. The upper pressure plate is driven to rotate by the stage 1 after pressing the glass sheet to be welded.

[0030] This design, with the upper pressure plate following the rotation of the stage 1, results in low equipment cost, simple structure, and suitability for scenarios with low welding precision requirements.

[0031] Furthermore, the height of the L-shaped diagonal fixing plate can be greater than the height of the glass sheet to be welded, so that the upper pressure plate can not only be driven to rotate by friction, but also be locked at the L-shaped diagonal fixing plate and rotated by the push of the L-shaped diagonal fixing plate, thus improving the stability when passively rotating.

[0032] In another embodiment, the pressing mechanism 3 includes a lifting component, an upper pressure plate rotatably disposed at the output end of the lifting component, and a driving component for actively rotating the upper pressure plate. The driving component is used to drive the upper pressure plate to rotate synchronously with the stage 1 after the upper pressure plate presses the glass sheet to be welded.

[0033] This design, with both the upper pressure plate and the stage 1 rotating actively, provides the system with high flexibility and operability, making it suitable for scenarios requiring high welding precision.

[0034] Specifically, the rotation direction and single rotation angle of the drive component are not specifically limited, as long as they meet the rotation adjustment requirements of the welding edge of the glass sheet to be welded.

[0035] Furthermore, the pressing mechanism 3 is also equipped with a pressure sensor to detect the downward pressure of the upper pressure plate on the glass sheet. Through the closed-loop feedback control system of the pressure sensor and the lifting component, the downward pressure can be precisely adjusted to avoid damage to the glass due to excessive pressure, while ensuring the stability of the pressing.

[0036] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0037] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0038] Additionally, "multiple" refers to two or more.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
