Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and particularly relates to a gluing and assembling integrated structure of a photovoltaic component. Background Art

[0002] Conventional photovoltaic modules (single glass or double glass) include an upper glass cover plate, solar cells, a lower base plate, and a junction box installed on the upper glass cover plate, which are arranged in order from top to bottom. The junction box includes a coil, a box body and a connector located opposite to the coil and extending in the same direction. When assembling the junction box, glue is first applied on the upper glass cover plate, and then the box body is glued to the glue application area. However, this assembly method has the following common problems:

[0003] 1) During the gluing process, due to the inability to quickly solidify or the position deviation of gluing and assembly, the box body after gluing is prone to shifting, causing the gluing area to change, which seriously affects the gluing and assembly quality;

[0004] 2) During the assembly process, the box body is usually only clamped, which can easily cause deviation at the moment of pressing and affect the gluing accuracy;

[0005] 3) Gluing and pressing are completely independent, which not only makes the mechanism complicated, but also makes the implementation more inconvenient;

[0006] 4) Once the glue head is not in use, if it is not sealed, it is easy to cause the glue head to be blocked due to long-term exposure, which is not conducive to the implementation of the next glue application. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an improved integrated structure of gluing and assembling of photovoltaic components.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0009] A photovoltaic module integrated gluing and assembly structure, comprising a gluing component and an assembly component, in particular, the gluing component and the assembly component are located on the same truss, and the gluing component comprises a gluing head capable of relative movement along three axes XYZ, and a glue head temporary storage platform, wherein the glue head temporary storage platform is provided with a mounting hole, the gluing head can be inserted into the mounting hole and the mounting hole is filled with an oil seal capable of sealing the gluing head; the assembly component comprises a box clamp, a coil clamp and a gluing auxiliary component, wherein the gluing auxiliary component is a beam curing component or a gluing auxiliary component is a tool based on visual correction.

[0010] Preferably, the mounting hole is filled with oil, and the glue head is inserted below the liquid level of the oil to form an oil seal. The oil seal prevents the glue head from being blocked or leaking.

[0011] In some specific embodiments, the oil is silicone oil. Silicone oil is used to seal the glue head because silicone oil has the effect of dissolving and volatilizing glue, and silicone oil will not affect the subsequent glue application.

[0012] According to a specific implementation and preferred aspect of the utility model, the coil clamp and the box body clamp are synchronously adjusted on the XYZ axis. Under the same set of drives, the junction box is stably clamped.

[0013] According to another specific implementation and preferred aspect of the utility model, the coil clamp is supported inside the coil or clamped outside the coil. Whether it is supported inside or clamped outside, auxiliary clamping can be implemented.

[0014] Preferably, the coil clamp comprises two clamp arms that rotate relative to each other to close or open, and a power device that drives the two clamp arms to move, so as to facilitate the clamping operation.

[0015] Preferably, the box body clamps are relatively clamped from both sides in the length direction of the box body.

[0016] According to another specific implementation and preferred aspect of the utility model, when the glue applied is UV glue, the gluing auxiliary components include a curing lamp, a curing seat and a curing lens, wherein the curing lens disperses the light beam to the gluing area.

[0017] Preferably, the curing lens is horizontally arranged on the curing seat, and the curing lamp is located above the curing lens, so as to facilitate the concentration and diffusion of the light beam to cover the glue application area.

[0018] In addition, the curing seat can be installed on the truss to be adjusted up and down, and the optical focal length can be adjusted to meet the actual use needs.

[0019] Preferably, when the glue used for gluing is AB glue, the tool includes a visual camera and a lighting assistant, wherein the visual camera, with the assistance of light, performs glue correction of the glue head and / or assembly correction of the junction box during gluing or assembly.

[0020] Due to the implementation of the above technical solution, the utility model has the following advantages compared with the prior art:

[0021] Based on the assembly of existing photovoltaic modules, during the gluing process, the box body after gluing is prone to shifting due to the inability to quickly solidify, causing the gluing area to change, seriously affecting the quality of the gluing assembly; at the same time, during the assembly process, the box body is generally only clamped, which can easily cause offset at the moment of pressing, affecting the gluing accuracy; in addition, gluing and pressing are completely independent, which not only makes the mechanism complicated, but also makes the implementation more inconvenient. Once the gluing head is not used, if it is not sealed, it is easy to cause the glue head to be blocked due to long-term exposure, which is not conducive to the next gluing implementation, etc. The utility model cleverly solves the various deficiencies of the existing structure by overall design of the gluing and assembly integrated structure of the photovoltaic module. After adopting the integrated gluing and assembly structure of the photovoltaic module, the gluing and assembly structures are relatively combined and installed on the same truss, and a mounting hole for forming an oil seal is used to implement glue head protection in the non-gluing state. Then, according to the type of glue, corresponding gluing auxiliary components are selected, such as light beam curing or visual correction, so that the assembly efficiency and quality are improved. At the same time, the assembly is carried out in the synchronous clamping of auxiliary clamping (coil clamping) and box body clamping to avoid displacement caused by junction box assembly. Therefore, on the one hand, the utility model optimizes the gluing and assembly structure for easy operation, and at the same time, the gluing head can be kept in an oil seal in the non-gluing state without leakage and blockage due to glue head curing. On the other hand, the auxiliary clamping (coil clamping) and box body clamping are synchronized to reduce the probability of displacement of the junction box during assembly, and according to the type of glue, corresponding gluing auxiliary components are selected, such as light beam curing or visual correction, so that the assembly efficiency and quality are improved.

The glue head 10 can be inserted into the mounting hole 110 and is below the liquid surface to form an oil seal.

It is convenient for the light beam to be concentrated and diffused to cover the gluing area. In addition, the curing seat 221 can be adjusted and installed on the truss J to move up and down. Adjust the light focal length to meet the needs of actual use.

[0041] In some specific embodiments, when the glue used for gluing is AB glue, the gluing auxiliary component 22 includes a visual camera 220 and a lighting assistant 221, wherein the visual camera 220, with the assistance of light, implements glue correction of the glue head and / or assembly correction of the junction box during gluing or assembly.

[0042] The implementation process of this embodiment is as follows:

[0043] After adopting the integrated gluing and assembling structure of the photovoltaic module, a glue frame is formed in the gluing area of ​​the photovoltaic module by the XYZ three-axis movement of the gluing head 10 according to the type of glue, and then the junction box is sent to the top of the gluing area through the clamping of the box body clamp 20 and the auxiliary clamping of the coil clamp 21. At the same time, with the assistance of the gluing auxiliary component 22, the junction box is glued to the designated installation area of ​​the photovoltaic module, that is, the assembly of the junction box is completed.

[0044] In summary, after adopting the integrated gluing and assembling structure of the photovoltaic module, the gluing and assembling structures are relatively combined and installed on the same truss, and the mounting holes for forming oil seals are used to implement the protection of the glue head in the non-gluing state. Then, according to the type of glue, the corresponding gluing auxiliary components are selected, such as beam curing or visual correction, so that the assembly efficiency and quality are improved. At the same time, the assembly is carried out in the synchronous clamping of the auxiliary clamping (coil clamping) and the box body clamping to avoid the displacement caused by the assembly of the junction box. Therefore, on the one hand, the utility model optimizes the gluing and assembling structure for easy operation, and at the same time, the gluing head can be kept in an oil seal in the non-gluing state without leakage and blockage caused by the curing of the glue head; on the other hand, the auxiliary clamping (coil clamping) The assembly is synchronized with the box body clamping to reduce the probability of displacement of the junction box during assembly, and at the same time, under light beam curing, the assembly efficiency and quality of the junction box are further improved; thirdly, an oil seal is used to avoid blockage or leakage of the glue head, and silicone oil is used to seal the glue head, because silicone oil has the effect of dissolving and volatilizing glue, and silicone oil will not affect subsequent gluing; fourthly, the coil clamp and the box body clamp are adjusted synchronously on the XYZ axis, that is, under the same set of drives, so as to facilitate the stable clamping of the junction box; fifthly, both the internal support and the external clamp can implement auxiliary clamping; sixthly, the glue is UV glue, and the curing component used is conventional light beam curing. The curing lens is horizontally arranged on the curing seat, and the curing light is located above the curing lens. In order to facilitate the concentration and diffusion of the light beam to cover the gluing area, the curing seat can be moved up and down and adjusted on the truss to adjust the light focal length to meet the actual needs of use; the seventh aspect is that the glue applied is AB glue, and the curing components are visual cameras and fill-in light tools, that is, two photos are taken before and after gluing. The photo before gluing is to see whether there is any deviation in the angle of the busbar in the Z-axis direction. If there is a deviation, the gluing position of the glue head is adjusted to compensate for the deviation; the second photo is taken after gluing and installing the junction box, which mainly serves the purpose of re-inspection after installation.
