Description

Technical Field

[0001] This disclosure belongs to the field of laminated frame technology, specifically relating to a practical and wear-resistant laminated frame. Background Technology

[0002] In today's booming photovoltaic market, the types of solar cell modules are constantly evolving, with single-glass and double-glass modules becoming the focus of attention. Considering the economics, efficiency, and convenience of projects, an increasing number of customers are requesting double-glass modules that can capture sunlight from both sides, representing a global product development trend in the solar energy industry.

[0003] Double-glass modules are made by sequentially laying out materials such as an upper tempered glass layer, an upper encapsulating film, solar cells, a lower encapsulating film, and a lower tempered glass layer, and then laminating them into a single unit using a high-temperature laminator. Traditional single-glass modules have thin and flexible organic backsheets, while double-glass modules have thicker and more rigid backsheets; the characteristics of these two materials differ significantly. If the lamination process for single-glass modules were directly used, double-glass modules would be prone to problems such as air bubbles and broken solar cells. To ensure process quality, the industry mainstream currently uses lamination frames for auxiliary protection in the lamination process of double-glass modules.

[0004] For example, Chinese patent application number 202223073417.X discloses a photovoltaic module lamination frame and lamination tooling. The lamination frame includes a metal reinforcing core and a plastic frame; the metal reinforcing core and plastic frame are combined to form a frame that can be fitted around a double-glass module; the metal reinforcing core is located on the four sides of the frame, and the plastic frame is located at the four corners of the frame; the plastic frame is made of a high-temperature resistant material. The lamination frame adopts a new structural design and is processed using a combination of metal and plastic injection molding, replacing the traditional all-metal structure and welding process. This strengthens the module's overvoltage resistance, optimizes corner glue overflow, reduces the overall weight of the lamination frame, and improves the problem of difficult handling during production. The lamination tooling includes the aforementioned lamination frame and straps; the straps are detachably fixed to the lamination frame, replacing the traditional rivet fixing method. This eliminates the need for repeated nailing during use, improves processing efficiency, and solves the problem of protruding rivets affecting the lamination effect.

[0005] Chinese Patent Application No. 202220854921.4 discloses a double-glass module lamination frame device, comprising: a lamination frame, wherein slide rails are formed on the inner walls of both sides of the lamination frame; a support strip is integrally formed at the middle position of the slide rails; multiple limiting holes are formed on the top of both sides of the lamination frame; and adjusting frames, wherein two adjusting frames are symmetrically arranged in the slide rails, and the two sides of the adjusting frames slide and guide each other with the slide rails on both sides of the lamination frame; multiple fixing plates are fixed at intervals on both sides of the adjusting frames, and fixing holes are formed on the fixing plates; and a limiting strip is fixed along the length direction of the two adjusting frames at their opposite ends. This invention, by setting slide rails on the lamination frame, facilitates the sliding of the adjusting frames to adjust the size between the two adjusting frames to match the size of the double-glass module to be laminated, improving the practicality and compatibility of the lamination frame, while also avoiding the need to replace the lamination frame, thus improving production efficiency.

[0006] Chinese patent application number 202322315472.3 discloses a lamination frame for preventing adhesive overflow and edge curling after lamination of photovoltaic double-glass modules. The lamination frame has a main lamination frame on its outer side, which is rectangular in shape. Each of the four inner corners of the main lamination frame has a combined limiting wall. A longitudinally symmetrical and parallel limiting band is arranged in the middle of the main lamination frame. The inner sides of the combined limiting walls are also equipped with obliquely oriented limiting bands. The limiting bands are located on the upper surface of the main lamination frame, and both ends of the limiting bands are connected to the surface of the main lamination frame by rivets. The combined limiting walls are integrally connected to the main lamination frame, and the combined limiting walls are obliquely axially symmetrical rectangular protruding walls. This lamination frame solves the problem of adhesive overflow and edge curling on the glass surface of photovoltaic double-glass modules after lamination. By solving the problem of adhesive overflow and edge curling on the glass surface, it saves on the additional labor costs required for subsequent processes and reduces the module defect rate.

[0007] However, there are still many shortcomings in actual production:

[0008] 1. Existing technology has countersunk rivet-connected limiting bandages in the middle and four corners of the laminated frame. Due to the limitations of existing processing technology, the thickness of the rivet position is usually too large, which poses a risk of air bubbles at the edge of the photovoltaic module.

[0009] 2. The existing photovoltaic double-glass module lamination process often uses a combination of sealing the long side of the module with adhesive tape and a lamination frame. During the lamination process, the high temperature squeezes the adhesive film to flow, and the molten adhesive will overflow along the short side and stick to the inner wall of the lamination frame. After lamination, it is not easy for employees to remove the frame. To improve this, the four sides of the lamination frame need to be wrapped with high-temperature cloth tape. However, the high-temperature cloth tape will wear out after high-frequency use, which makes the lamination frame need to be repaired frequently. Utility Model Content

[0010] The purpose of this disclosure is to provide a practical and wear-resistant laminated frame to solve the problems mentioned in the background art. The practical and wear-resistant laminated frame provided by this disclosure has the characteristics of reducing lamination bubbles in photovoltaic modules, lowering costs, and reducing subsequent maintenance costs.

[0011] To achieve the above objectives, this disclosure provides the following technical solution: a practical wear-resistant laminated frame, comprising a laminated frame body, several parallel first limiting bandages connected to the upper part of the two long sides of the laminated frame body, and second limiting bandages connected to the four corners of the laminated frame body, the ends of the first limiting bandages and the second limiting bandages being bonded to the laminated frame body by a high-temperature resistant adhesive.

[0012] Furthermore, in this disclosure, the high-temperature resistant adhesive is a fluororubber adhesive.

[0013] Furthermore, in this disclosure, both the first and second limiting bandages are made of Teflon.

[0014] Furthermore, in this disclosure, the laminate frame body is made of aluminum alloy.

[0015] To further increase the overall strength of the laminate frame body 1, reinforcing pads are connected above the four corners of the laminate frame body.

[0016] To prevent the sol from overflowing and sticking to the inner wall of the laminating frame, thus facilitating removal of the laminating frame after lamination and eliminating the need for high-temperature tape, reducing costs and overall weight, and simplifying maintenance, a high-temperature resistant anti-stick coating is applied to the surface of the laminating frame. This high-temperature resistant anti-stick coating is either a rubber coating or a Teflon coating.

[0017] To improve the sealing effect at the lead-out holes during the lamination of double-glass photovoltaic modules and reduce adhesive overflow at these locations, an auxiliary pressure block corresponding to the lead-out holes is further provided on the first limiting bandage located in the middle of the lamination frame body. The auxiliary pressure block is made of resin.

[0018] In order to meet the needs of subsequent automated production and improve the efficiency of assembly line operations, a barcode scanning slot is provided on the first limiting bandage located in the middle of the laminate frame body.

[0019] Compared with the prior art, the beneficial effects of this disclosure are:

[0020] 1. The ends of the first and second limiting bandages of this disclosure are bonded to the laminated frame body with high-temperature resistant adhesive. This can effectively reduce the thickness at the connection between the ends of the first and second limiting bandages and the laminated frame body, and can ensure the consistency of thickness as much as possible. This avoids the risk of excessive thickness in some areas due to the use of rivet connections in the prior art, which could lead to bubbles easily forming at the edges of the photovoltaic module.

[0021] 2. The present invention provides that reinforcing pads are welded above the four corners of the laminate frame body to increase the overall strength of the laminate frame body.

[0022] 3. This disclosure involves spraying a high-temperature resistant, non-stick coating onto the surface of the laminate frame body to prevent the molten adhesive from overflowing and sticking to the inner wall of the laminate frame body. This makes it easier to remove the laminate frame body after lamination, eliminating the need for high-temperature resistant tape. This not only reduces costs and lightens the overall weight of the laminate frame body, but also facilitates later maintenance, thereby reducing maintenance costs.

[0023] 4. By setting an auxiliary pressure block, this disclosure can effectively improve the sealing effect at the lead wire position during the lamination of double-glass photovoltaic modules and improve the overflow of adhesive at the lead wire position.

[0024] 5. This disclosure, through the setting of the barcode scanning slot, can meet the needs of subsequent automated production, thereby improving the efficiency of assembly line operations. Attached Figure Description

Second limiting bandages 6 are connected to the four corners of the laminated frame body 1. The first limiting bandages 2 and the second limiting bandages 6 are both made of Teflon. Since Teflon has a low surface energy, it is not easy to bond with other substances such as metals. Therefore, its surface energy can be improved by sodium naphthalene chemical treatment to improve adhesion, thereby ensuring the bonding effect between the first limiting bandages 2 and the second limiting bandages 6 and the laminated frame body 1. The ends of the first limiting bandages 2 and the second limiting bandages 6 are bonded to the laminated frame body 1 by a high-temperature resistant adhesive, which is a fluororubber adhesive.
