Description

Technical Field

[0001] This utility model belongs to the field of electronic adhesive technology, and specifically relates to a dispensing device for gasket adhesive used in solar cell encapsulation. Background Technology

[0002] The gasket adhesive for solar cell encapsulation is butyl rubber. Butyl rubber improves the adhesion between the solar cell backsheet and other component parts, thus providing better support and stability for the entire photovoltaic module. As an adhesive between photovoltaic cells, the high elasticity of butyl rubber can accommodate the expansion and contraction of the photovoltaic cells during temperature changes, avoiding stress and cracking. Butyl rubber has extremely low air and water permeability and a highly saturated molecular structure, which gives it good weather resistance and chemical stability. Furthermore, the tackifying components of butyl rubber contain tackifying resins and fillers, which make the gasket prone to strong adhesion upon contact, resulting in easy deformation and strong adhesion. Currently, there is no packaging device specifically designed for this gasket adhesive. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a reasonably designed, simple, space-saving and cost-saving dispensing device for solar cell encapsulation gasket adhesive, which addresses the shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dispensing device for gasket adhesive used in solar cell encapsulation is characterized by comprising a dispensing box, a sealing film used as a sealing box cover, and a cutting mold used in conjunction with the sealing film. The dispensing box has several squares for dispensing the gasket adhesive, and the top of the side walls between adjacent squares are reserved with communicating notches. At least one square contains a desiccant. The cutting mold has a cutting plate for covering the opening of the dispensing box. The cutting plate has symmetrically arranged U-shaped grooves on both sides for scissors or cutters to insert into and cut the sealing film. The U-shaped grooves have cutting inlets and outlets at both ends.

[0006] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the shearing plate is symmetrically provided on both sides with a lower edge covering the top of the packaging box, and a U-shaped groove is provided on the outer wall of the lower edge.

[0007] The technical problem to be solved by this utility model can also be achieved through the following technical solution: an acrylic pressure-sensitive adhesive layer is provided on the side of the sealing film that is in contact with the packaging box.

[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the sealing film is a transparent PET protective film, which makes it easy to see the condition of the gasket adhesive inside the square.

[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the length of the packaging box is 40cm, the width is 20cm, and the depth is 1cm.

[0010] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the sealing film is 42cm long, 22cm wide, and 30μm-80μm thick.

[0011] Compared with the prior art, this utility model sets up several squares to separate the gasket adhesive for each solar cell encapsulation, effectively avoiding deformation and adhesion of the gasket adhesive. By setting up a sealing film, notch and desiccant, it ensures that each product in the square is not damp, thus guaranteeing the quality of each product. By setting up a cutting mold, it is easy to cut the sealing film to a fixed size, so that the sealing film can be adapted to the packaging box and facilitate quick sealing.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Reference Figures 1-3 A dispensing device for gasket adhesive used in solar cell encapsulation includes a dispensing box, a sealing film used as a sealing cover, and a cutting die used in conjunction with the sealing film. The cutting die is used to cut the sealing film to match the opening of the dispensing box.

[0019] The packaging box contains several squares 1 for dispensing the gasket adhesive. The top of the side wall between adjacent squares 1 is reserved with a connecting notch 2. At least one square 1 is filled with a desiccant. Because butyl rubber is sensitive to humidity, humidity fluctuations will cause changes in the hygroscopicity of butyl rubber, resulting in dimensional instability, interface failure or material deterioration. Therefore, two squares in the packaging box are reserved for desiccant to ensure that each product in the box is not exposed to moisture.

[0020] The shearing mold is provided with a shearing plate 3 for covering the opening of the packaging box. The area of ​​the shearing plate 3 is slightly larger than the opening area of ​​the packaging box. The shearing plate 3 is provided with U-shaped grooves 4 on both sides for scissors or cutting knives to insert into and cut the sealing film. The U-shaped grooves 4 are provided with cutting inlets and outlets at both ends.

[0021] The shearing plate has symmetrical lower edges 5 covering the top edge of the packaging box. U-shaped grooves are provided on the outer side wall of the lower edge 5. This not only allows the sealing film to be directly pressed onto the top of the packaging box, but also enables the sealing film to be quickly positioned and sealed to the packaging box. The height of the lower edge should not be too high, generally 10mm-15mm. The length of the lower edge is the same as the length of the shearing plate, and the thickness of the lower edge is 5mm-10mm.

[0022] The dispensing device described in this utility model includes a dispensing mold box with dimensions of 40cm in length, 20cm in width, and 1cm in depth. It contains 50 neatly arranged 2.2*2.2cm² squares. Each square has a concave notch on all four sides at the top. Because butyl rubber is sensitive to humidity, fluctuations in humidity can cause changes in its hygroscopicity, leading to dimensional instability, interface failure, or material deterioration. Therefore, two compartments in the mold box are specifically for storing desiccants to ensure that each product inside remains dry. The mold box is made of transparent plastic.

[0023] Sealing box lid: 42cm long, 22cm wide, 30μm-80μm thick. Both sides of the PET transparent protective film are coated with acrylic pressure-sensitive adhesive. This adhesive allows for rapid bonding upon contact, exhibiting high adhesion and good ductility, enabling easy and repeated application to packaging molds and sealing of products. It also facilitates inspection; if defective products are found, simply peel off part of the PET protective film, replace the defective product, and re-apply (can be repeated several times).

[0024] Sealing box lid cutting mold: Since the PET film is sold in 20cm rolls, a matching cutting mold of the same size is provided. Pull the PET film off the roll, secure it to the mold with transparent tape, and wrap the PET film around the mold, covering the U-shaped opening. Finally, use scissors or a knife to cut the film from one end of the U-shape. The resulting PET film will be 20cm wide and 20-22cm long, completely covering the packaging mold box.

[0025] The operator places the trimmed butyl rubber gaskets into the grid, cuts a piece of sealing film from the cutting edge on the shearing plate, and then covers it with the sealing film. The packaging box is reusable, convenient to use, lightweight, low-cost, and saves a lot of manpower.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
