Description

Technical Field

[0001] The present invention relates to a solar photovoltaic component lamination structure, in particular to a solar photovoltaic component tooling-free lamination structure applied to the technical field related to laminating machines. Background Art

[0002] At present, in the production of solar cell double-glass (i.e. double-layer glass components, both sides of the components are glass) components, because the thickness of double-glass components is twice that of single-glass components, such as Figure 6 As shown in the prior art 1 in the lamination process, the silicone plate is pressed down, which generates additional pressure on the edges and corners of the component, thereby causing product defects such as lack of glue, bubbles, uneven thickness, and reverse warping of glass. There are currently two solutions: First, the Chinese patent CN221327731U specification discloses a photovoltaic lamination tooling, which uses a corner guard or a lamination tooling (a press frame is also called a frame, and the names in the industry are not uniform, but they all have the same function, and are uniformly referred to as a press frame below), such as Figure 6 As shown in the prior art 2, the lamination tool is used as an auxiliary lamination tool to ensure the lamination quality of the double-glass components. The press frame is generally made of aluminum alloy, with a width of about 3 cm. The component is framed in the middle like a photo frame to maintain the horizontality after the rubber plate is pressed down, and to ensure that the center and four corners of the component are subjected to consistent pressure. During the use of the process, the press frame needs to be placed on the feed side of the laminator, and it needs to be removed on the discharge side after the lamination is completed, and transported back to the feed side to wait for use. As a result, automated equipment such as press frame busbars were born, which are used for automatic frame removal, frame placement, and transmission. However, the press frame is a consumable item and needs to be replaced regularly. During lamination, the press frame needs to be repeatedly removed and placed. Accordingly, an automatic control mechanism for taking and placing the press frame needs to be set, and the cost investment is also high.

[0003] Second, high-precision servo alignment and high-precision transmission are used to transport the components to the designated area on the high-temperature cloth under the laminator. Advantages: The flexible or corner guard is glued to the high-temperature cloth to form a laminating tooling. This solution avoids the need to take and place the tooling every time. Disadvantages: It requires the cooperation of the servo alignment system, servo transmission system, and high-temperature cloth customization, which is costly. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the edges of photovoltaic modules are susceptible to uneven force during lamination, and the costs of the two solutions in the prior art are both high.

[0005] In order to solve the above problems, the present invention provides a non-tooling laminated structure of a solar photovoltaic module, comprising a heating plate, an upper cover plate located above the heating plate, and a pressure strip and a rubber plate located between the upper cover plate and the heating plate, the pressure strip and the upper cover plate are fixedly connected by bolts, the rubber plate is located between the pressure strip and the upper cover plate, and the rubber plate simultaneously contacts the two, the upper and lower ends of the pressure strip are inlaid with O-rings, the upper and lower O-rings contact the rubber plate and the heating plate respectively, the inner walls of the pressure strip close to each other on the left and right sides are both chiseled with installation grooves, the two installation grooves are both installed with elastic connecting strips, a pad is fixedly connected between the two elastic connecting strips, and the pad is located below the rubber plate; The pad includes a plurality of force equalizing plates fixed to each other and two force unloading plates respectively located on both sides of the plurality of force equalizing plates. One force equalizing plate corresponds to one photovoltaic module to be laminated, and the force unloading plate is dynamically connected to the adjacent force equalizing plates.

[0006] In the above-mentioned tooling-free lamination structure of solar photovoltaic components, by adding a pad, stable and uniform lamination of solar photovoltaic panels can be achieved without tooling. Compared with the existing technology, the lamination tooling can be eliminated, and then the related automation equipment set for the lamination tooling can be eliminated, thereby greatly reducing the production cost of solar photovoltaic panels.

[0007] As a further improvement of the present application, the dynamic connecting part includes a connecting plate layer fixedly connected between the force unloading plate and the adjacent force equalizing plate, and a movable inclined plate and a fixed inclined plate respectively fixedly connected to the force unloading plate and the force equalizing plate at one end close to each other. The upper end of the connecting plate layer is flush with the top of the force equalizing plate and the force unloading plate, and the lower ends of the fixed inclined plate and the movable inclined plate are respectively flush with the lower ends of the force equalizing plate and the force unloading plate.

[0008] As a further improvement of the present application, the force equalizing plate is made of a lightweight hard material, and the connecting plate layer and the force unloading plate are made of an elastic material.

[0009] As a further improvement of the present application, the ends of the fixed inclined plate and the movable inclined plate that are close to each other are both inclined surfaces, and when the force equalizing plate and the force unloading plate are both horizontal, the two inclined surfaces are not parallel to each other, and when the force unloading plate is bent by 2°, the movable inclined plate is parallel to and in conflict with the inclined surfaces of the fixed inclined plate, and the fixed inclined plate and the movable inclined plate are both hard structures.

[0010] As another improvement of the present application, the dynamic connection adopts a vertical sliding component to realize the connection between the force unloading plate and the force equalizing plate. The force unloading plate is slidingly connected to the force equalizing plate through the vertical sliding component, and the end faces of the force equalizing plate and the force unloading plate that are close to each other are in contact with each other.

[0011] As another improved supplement of the present application, the force unloading plate includes a hard translation section close to one side of the force equalizing plate and an elastic section fixedly connected to the end of the hard translation section away from the force equalizing plate, and a balance detection unit is arranged at the lower end of the hard translation section.

[0012] As another improved supplement of the present application, the balance detection unit includes two elastic convex bags fixedly embedded in the lower end of the hard translation section, an air guide straight tube fixedly embedded inside the hard translation section, and a sensing block arranged in the middle of the lower end of the hard translation section. The elastic convex bag, the air guide straight tube and the bellows on the same side are interconnected and filled with compressed air. A central groove is opened in the middle of the lower end of the hard translation section, and the sensing block is located in the central groove. The lower end of the air guide straight tube is also fixedly connected to a bellows. The lower ends of the two bellows movably pass through the hard translation section and are fixedly connected to the left and right upper ends of the sensing block, respectively.

[0013] As another improved supplement of the present application, the sensing block includes a limiting rope, a pressure sensor fixedly connected to the middle part of the lower end of the limiting rope, and two limiting ropes fixedly connected between the left and right ends of the supporting plate and the inner wall of the central groove, respectively. The limiting rope is made of elastic material, the supporting plate is made of hard material, and the distance between the supporting plate and the top of the central groove is smaller than the distance between the lower end of the pressure sensor and the mouth of the central groove.

[0014] To sum up, by adding a pad, stable and uniform lamination of solar photovoltaic panels can be achieved without tooling. Compared with the existing technology, the lamination tooling can be eliminated, and then the relevant automation equipment for the lamination tooling can be eliminated, thereby greatly reducing the production cost of solar photovoltaic panels; during lamination, the edge of the pad can move down with the rubber plate and contact with the heating plate, and then the lamination tooling can be automatically formed. On the one hand, it can effectively avoid the situation where the edge of the solar photovoltaic panel is subjected to excessive local force due to excessive deformation of the rubber plate. On the other hand, due to the setting of the pad, the rubber plate does not directly contact the solar photovoltaic component during lamination, and its upper and lower deformation amplitude is reduced, which can effectively extend its service life, reduce the frequency of rubber plate replacement, and reduce the impact on the lamination process.

DETAILED DESCRIPTION

[0017] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0018] The first implementation method: Figure 1-2 A tooling-free lamination structure of a solar photovoltaic module is shown, in which a represents a photovoltaic module to be laminated, including a heating plate 2, an upper cover plate 1 located above the heating plate 2, and a pressure strip 3 and a rubber plate 4 located between the upper cover plate 1 and the heating plate 2. The pressure strip 3 and the upper cover plate 1 are fixedly connected by bolts, the rubber plate 4 is located between the pressure strip 3 and the upper cover plate 1, and the rubber plate 4 is in contact with both of them at the same time. O-rings are inlaid at both ends of the pressure strip 3, and the upper and lower O-rings are in contact with the rubber plate 4 and the heating plate 2 respectively. The inner walls of the pressure strip 3 that are close to each other on the left and right are both provided with installation grooves 401, and elastic connecting strips 5 are installed in the two installation grooves 401, and a pad 6 is fixedly connected between the two elastic connecting strips 5.

[0019] like Figure 4The backing plate 6 is located below the rubber plate 4. The backing plate 6 includes a plurality of force-equalizing plates 61 fixed to each other and two force-releasing plates 62 respectively located on both sides of the plurality of force-equalizing plates 61. One force-equalizing plate 61 corresponds to one photovoltaic module to be laminated. The force-releasing plate 62 is dynamically connected to the adjacent force-equalizing plates 61. The force-equalizing plates 61 are made of a lightweight hard material. The connecting plate layer 63 and the force-releasing plate 62 are both made of an elastic material. Before lamination, firstly place a plurality of photovoltaic panel modules to be laminated on top of the heating plate 2, and then The upper cover plate 1 is controlled to move downward, driving the rubber plate 4 to move downward and contact the upper end of the heating plate 2, so that a lamination cavity is formed between the upper cover plate 1 and the heating plate 2, and an upper pressure cavity and a lower pressure cavity are formed under the separation of the rubber plate 4. During lamination, the lower pressure cavity is first evacuated, and then the gas is filled into the upper pressure cavity, so that the two produce a significant pressure difference change, so that the rubber plate 4 is deformed downward, thereby pushing the pad 6 to move downward. At this time, multiple force equalizing plates 61 move downward accordingly and generate extrusion force with multiple photovoltaic panel components to be laminated, such as Figure 3 and Figure 5 At the same time, the unloading plate 62 moves downward and deforms, thereby contacting the lower end of the heating plate 2. In this process, compared with Figure 6 In the prior art 1, the rubber sheet 4 is not easy to be greatly deformed at the edge of the photovoltaic panel assembly, and the rubber sheet 4 does not directly act on the photovoltaic panel assembly, thereby effectively avoiding uneven force at the corner, effectively protecting the photovoltaic panel assembly, and making its edge less likely to be damaged. Figure 6 According to the prior art 2, there is no need to set up a frame pressing tool, and a series of equipment brought by the frame pressing tool also do not need to be set up, thereby significantly reducing costs.

[0020] The dynamic connection is achieved by the elasticity of the force unloading plate 62 so that the angle between the force unloading plate 62 and the force equalizing plate 61 can change when subjected to force.

[0021] It is worth noting that the thickness of the pad 6 can be specifically set according to the space of the lamination cavity and the thickness of the photovoltaic panel assembly, so that when the end of the force unloading plate 62 contacts the heating plate 2, its bending angle is about 2°, which is very small and not enough to affect the edge of the photovoltaic panel assembly.

[0022] In the above-mentioned solar photovoltaic component tool-free lamination structure, by adding a pad 6, stable and uniform lamination of the solar photovoltaic panels can be achieved without a tool. Compared with the prior art, the lamination tool can be eliminated, and then the relevant automation equipment for the lamination tool placement can be eliminated, thereby greatly reducing the production cost of the solar photovoltaic panels. In addition, due to the setting of the pad 6, the pulling amplitude of the rubber sheet 4 during lamination can be significantly reduced, protecting it from damage, thereby effectively increasing the lamination times of the rubber sheet 4.

[0023] The second implementation method: This implementation further improves the dynamic connection based on the first implementation, and the rest of the implementation remains the same as the first implementation.

[0024] Figure 7 As shown, the dynamic connection adopts a dynamic connector to realize the connection between the force equalizing plate 61 and the force unloading plate 62. The dynamic connector includes a connecting plate layer 63 fixedly connected between the force unloading plate 62 and the adjacent force equalizing plate 61, and a dynamic inclined plate 82 and a fixed inclined plate 81 respectively fixedly connected to the end of the force unloading plate 62 and the force equalizing plate 61 close to each other. The upper end of the connecting plate layer 63 is flush with the top of the force equalizing plate 61 and the force unloading plate 62, and the lower ends of the fixed inclined plate 81 and the dynamic inclined plate 82 are respectively flush with the lower ends of the force equalizing plate 61 and the force unloading plate 62. Figure 8 The ends of the fixed inclined plate 81 and the movable inclined plate 82 that are close to each other are both inclined surfaces, and when the force equalizing plate 61 and the force unloading plate 62 are both horizontal, the two inclined surfaces are not parallel to each other. When the force unloading plate 62 is bent by 2°, the inclined surfaces of the movable inclined plate 82 are parallel to and in conflict with the fixed inclined plate 81, and the fixed inclined plate 81 and the movable inclined plate 82 are both hard structures.

[0025] During lamination, when the unloading plate 62 is bent downward under the pressure of the rubber plate 4, the connection plate layer 63 is provided to reduce the vertical deformation amplitude when subjected to force, and its elasticity can prevent the connection between the unloading plate 62 and the equalizing plate 61 from deforming under the condition of large stress accumulation. Figure 8 Under the support of the hard inclined surfaces of the fixed inclined plate 81 and the movable inclined plate 82, the force unloading plate 62 can have a stable contact surface after bending, so that its deformation is relatively stable, and it is not easy to cause a large deformation of the lower edge of the connection between the force equalizing plate 61 and the force unloading plate 62, thereby further reducing the impact on the edge of the photovoltaic panel assembly at that location.

[0026] The third implementation method: This embodiment makes another improvement on the dynamic connection based on the first embodiment, and the rest of the embodiments are consistent with the first embodiment.

[0027] Fig. 9 As shown, the dynamic connection adopts a vertical sliding component to realize the connection between the force unloading plate 62 and the force equalizing plate 61. The force unloading plate 62 is slidably connected to the force equalizing plate 61 through the vertical sliding component, and the end surfaces of the force equalizing plate 61 and the force unloading plate 62 that are close to each other contact each other. The force unloading plate 62 includes a hard translation segment 622 close to one side of the force equalizing plate 61 and an elastic segment 621 fixedly connected to the hard translation segment 622 at the end away from the force equalizing plate 61. During lamination, since the hard translation segment 622 is vertically slidably connected to the force equalizing plate 61, due to the downward extrusion force of the rubber sheet 4, it moves vertically along the end of the force equalizing plate 61 until it conflicts with the heating plate 2. At this time, it can spontaneously form a similar elastic structure at the edge of the photovoltaic panel assembly. Figure 6The pressing frame tooling of the prior art 2 is different from the pressing frame tooling of the prior art 2, but here, it is integrated with the pad 6, and its movement is controlled by the rubber plate 4. There is no need to set up corresponding equipment to control the placement of the pressing frame tooling, so it can still achieve the effect of reducing costs.

[0028] like Figure 10-11 A balance detection unit is provided at the lower end of the hard translation section 622, and the balance detection unit includes two elastic convex bags 71 respectively fixedly embedded in the lower ends of the hard translation section 622, an air guide straight pipe 72 fixedly embedded in the inside of the hard translation section 622, and a sensing block arranged in the middle of the lower end of the hard translation section 622. The elastic convex bag 71, the air guide straight pipe 72 and the bellows 73 on the same side are interconnected and filled with compressed air. A central groove 601 is opened in the middle of the lower end of the hard translation section 622, and the sensing block is located in the central groove 601. The lower end of the air guide straight pipe 72 is also fixedly connected to the bellows 73, and the lower ends of the two bellows 73 movably penetrate the hard translation section 622 and are respectively fixedly connected to the left and right upper ends of the sensing block.

[0029] The sensing block includes a limiting rope 92, a pressure sensor 93 fixedly connected to the middle part of the lower end of the limiting rope 92, and two limiting ropes 92 respectively fixedly connected between the left and right ends of the supporting plate 91 and the inner wall of the central groove 601. The limiting rope 92 is made of elastic material, the supporting plate 91 is made of hard material, and the distance between the supporting plate 91 and the top of the central groove 601 is smaller than the distance between the lower end of the pressure sensor 93 and the mouth of the central groove 601.

[0030] When the hard translation section 622 is pressed downward by the rubber plate 4, the two downwardly convex elastic convex capsules 71 will first contact the heating plate 2. Fig.13 When the hard translation section 622 moves downward steadily, the two elastic convex capsules 71 contact the heating plate 2 at the same time. At this time, the compressed gas on both sides will synchronously push the bearing plate 91 to make it move downward steadily, thereby causing the pressure sensor 93 to generate force data, such as Fig.12 When the hard translation section 622 is unbalanced, the support plate 91 will be subjected to unilateral force, causing the support plate 91 to tilt on one side, thereby causing the pressure sensor 93 to tilt and fail to generate force data. Based on this, the situation of the force unloading plate 62 can be effectively monitored during lamination, and it can be effectively ensured that it is in balanced contact with the heating plate 2 to form a stable limit at the edge of the photovoltaic panel assembly before the lamination is terminated, so that the photovoltaic panel assembly is effectively restricted during lamination, thereby effectively ensuring the lamination effect, so that the two glass plates in the photovoltaic panel assembly are not prone to relative displacement during lamination. At the same time, the data can also assist in monitoring the rubber plate 4. When the rubber plate 4 is damaged, it is difficult to deform as expected, resulting in the pressure sensor 93 being unable to generate data, or the generated data is significantly different from the expected data, which is convenient for the staff to replace the rubber plate 4 in time to ensure the lamination effect.

[0031] It is worth noting that Fig.12 When one side of the supporting plate 91 contacts the inner wall of the central groove 601 , as the supporting plate 91 continues to be subjected to unilateral force, the pressure sensor 93 never contacts the inner wall of the central groove 601 .

[0032] In summary, by adding a pad 6, stable and uniform lamination of solar photovoltaic panels can be achieved without a tool. Compared with the prior art, the lamination tool can be eliminated, and the relevant automation equipment set for the lamination tool can be eliminated, thereby greatly reducing the production cost of solar photovoltaic panels; during lamination, the edge of the pad 6 can move down with the rubber sheet 4 and contact with the heating plate 2, and then the lamination tool can be automatically formed. On the one hand, it can effectively avoid the situation where the edge of the solar photovoltaic panel is subjected to excessive local force due to excessive deformation of the rubber sheet 4. On the other hand, due to the setting of the pad 6, the rubber sheet 4 does not directly contact the solar photovoltaic component during lamination, and its upper and lower deformation amplitude is reduced, thereby effectively extending its service life, reducing the frequency of rubber sheet replacement, and reducing the impact on the lamination process.

[0033] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
