Description

Technical Field

[0001] This application relates to the field of photovoltaic module assembly mechanism technology, and in particular to a photovoltaic frame adhesive application and pressing system. Background Technology

[0002] In the field of photovoltaic (PV) module assembly technology, the gluing and framing process is crucial. With the continuous development of the PV industry, the performance and quality requirements for PV modules are becoming increasingly stringent. Gluing and framing enhances the sealing and stability of PV modules, providing excellent waterproofing and dustproofing; it also improves the durability of PV modules, enabling them to withstand harsh environments such as high and low temperatures; simultaneously, it firmly bonds multiple internal components together, protecting internal parts and preventing module damage caused by loosening or cracking. These characteristics are of great significance for the long-term stable operation of PV modules in different regions, promoting the widespread application of the PV industry in more areas.

[0003] A Chinese patent with authorization announcement number CN202134566U discloses a frame fixing and pressing device for a solar panel, which includes a conveyor belt formed by two or more sets of pulleys, a fixed bracket arranged perpendicularly to the conveyor belt and located at its lower part, a slide plate on the fixed bracket that is parallel to both sides of the conveyor belt, the slide plate being connected to the fixed bracket via a longitudinal slide rail, a pressing component matching the frame being provided on the slide plate, a plurality of longitudinal drive cylinders being connected to the slide plate, a liftable positioning rod on the conveyor belt, and a positioning sensor being provided on the positioning rod. The working process is as follows: First, the solar panel is positioned by the rising positioning rod. After the positioning sensor detects the solar panel, the conveyor belt stops moving. At this time, the lifting device smoothly lowers the four corners of the solar panel on the frame fixing and pressing device onto the right-angle plate. Driven by the horizontal and vertical drive cylinders, the initially assembled frame is correctly positioned, pressed, and fixed. The fixing baffle ensures the straightness of the frame during the fixing and pressing process, and plays a role in fixing the position of the frame. After the frame is fixed, it goes through the process of the flat pressure hammer. The flat pressure hammer rotates to the working position, and the flat pressure lifting cylinder presses the frame together in the same plane to avoid misalignment and affect the processing quality. After the fixing and pressing process is completed, the frame fixing and pressing device rises by the lifting device, the positioning rod descends, and if the positioning sensor no longer detects the solar panel, it feeds back to the control device. The control device then controls the conveyor belt to start working and transport the solar panel to the next process.

[0004] The aforementioned technologies have the following drawbacks: after the pressing is completed, the adhesive has not yet cured, and the photovoltaic modules still need to be transferred to the next process for heating and curing, which is inconvenient and needs to be improved. Utility Model Content

[0005] To promote the curing of adhesive after the photovoltaic modules are pressed together and improve the curing efficiency, this application provides a photovoltaic frame adhesive application and pressing system.

[0006] A photovoltaic frame gluing and pressing system includes a photovoltaic conveying mechanism. A frame preheating chamber and a frame conveying mechanism are arranged on the side of the photovoltaic conveying mechanism. The frame conveying mechanism passes through the frame preheating chamber in the middle. A traveling track is arranged above the outlet of the frame preheating chamber. A traveling trolley is arranged on the traveling track. The traveling trolley is equipped with a clamping mechanism for transferring the frame and a gluing mechanism for gluing the frame.

[0007] By adopting the above technical solution, the frame is preheated by the frame preheating chamber, and after being glued by the glue applicator, it is pressed with the photovoltaic module, which can promote the curing of the glue after pressing and improve the curing efficiency. Furthermore, the frame is transferred by the clamping mechanism of the traveling trolley, and the glue applicator applies glue to the frame, thus realizing the glue applicator and transfer functions of the frame.

[0008] Preferably, the frame preheating chamber includes a chamber body and several heating pipes, the heating pipes are located inside the chamber body, and a section of the frame conveying mechanism located inside the chamber body is positioned above the heating pipes.

[0009] By adopting the above technical solution, the frame preheating chamber consists of a chamber body and an internal heating pipe, and the frame conveying mechanism is located inside the chamber body above the heating pipe. This allows for preheating of the frame during the conveying process, promoting the curing of the adhesive after the photovoltaic modules are pressed together, and improving the curing efficiency.

[0010] Preferably, the frame conveying mechanism includes a conveying frame, the conveying frame being rotatably equipped with at least two conveying rollers, a conveyor belt being wound around the outside of the conveying rollers, and the conveying frame being equipped with a conveying drive for driving the conveying rollers to rotate.

[0011] By adopting the above technical solution, the conveyor drive can drive the conveyor roller to rotate, thereby driving the conveyor belt to operate and realize the conveying of the frame, which provides convenience for subsequent gluing and pressing processes.

[0012] Preferably, a section of the conveyor frame located inside the hopper is rotatably equipped with several support rollers, the diameter of which is smaller than that of the conveyor roller, and the top of the support rollers is flush with the top of the conveyor roller.

[0013] By adopting the above technical solution, several support rollers with a diameter smaller than the conveying roller and whose tops are flush with the tops of the conveying roller are set in a section of the conveying frame placed inside the chamber. This can provide additional support when conveying the frame, making the frame conveying more stable and facilitating subsequent gluing and pressing processes.

[0014] Preferably, there are two or more conveyor belts, and a heat-permeable gap is provided between adjacent conveyor belts.

[0015] By adopting the above technical solution, with two or more conveyor belts and heat-permeable gaps between them, the heat generated by the heating tubes can be better transferred to the frame, promoting frame preheating, ensuring preheating effect, and thus promoting the curing of adhesive after the subsequent photovoltaic module is pressed together, improving curing efficiency.

[0016] Preferably, an air supply mechanism is provided below both sides of the photovoltaic conveying mechanism in the conveying direction. The air supply mechanism includes a housing, which is a cylindrical structure that is vertically arranged and open at both ends. The housing has heating wires inside and a fan is provided at the bottom of the housing.

[0017] By adopting the above technical solution, a vertically open cylindrical shell air supply mechanism with heating wires and fans is set on both sides below the photovoltaic conveying mechanism in the conveying direction. Hot air can be blown to the edge of the photovoltaic panel for preheating, thereby further promoting the curing of the adhesive after the photovoltaic module is pressed together and improving the curing efficiency.

[0018] Preferably, a protective mesh cover is provided at the top opening of the housing.

[0019] By adopting the above technical solution, a protective mesh cover is installed at the top opening of the air supply mechanism housing. This can promote the curing of the adhesive after the photovoltaic modules are pressed together and improve the curing efficiency, while reducing the entry of foreign objects into the air supply mechanism, so as to ensure the normal operation of the air supply mechanism.

[0020] Preferably, there are two walking tracks, each equipped with a corresponding walking trolley. A mounting plate connects the two walking trolleys, and a sliding block is slidably connected to the mounting plate. The mounting plate is equipped with a moving mechanism for driving the sliding block to slide. The sliding block is connected to the glue dispensing mechanism through an adjustment mechanism, which is used to control the height of the glue dispensing mechanism.

[0021] By adopting the above technical solution, the slide is connected to the glue-applying mechanism through an adjustment mechanism to control the height of the glue-applying mechanism. This allows the glue-applying mechanism to adjust its height over a wider range, thereby enabling more precise glue application to the frame and improving accuracy. Furthermore, the moving mechanism allows the glue-applying mechanism to follow the clamping mechanism during frame gripping and transport. By coordinating with the moving mechanism to move the glue-applying mechanism, glue application can be performed during frame transport, completing the application before the frame reaches the designated position. This effectively utilizes the frame transport time and improves the efficiency of the glue-applying process.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The frame conveying mechanism passes through the frame preheating chamber in the middle, which can preheat the frame to promote the curing of the adhesive after the photovoltaic modules are pressed together and improve the curing efficiency;

[0024] 2. An air supply mechanism is installed below both sides of the photovoltaic conveying mechanism in the conveying direction, which can further promote the curing of the adhesive;

[0025] 3. This solves the problem that the adhesive needs to be transferred to the next process for heating and curing after the existing equipment has finished pressing, which is inconvenient and affects production efficiency. Attached Figure Description

[0038] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0039] This application mainly adopts a photovoltaic conveying mechanism combined with frame preheating and adhesive pressing, which achieves the effect of promoting adhesive curing after photovoltaic module pressing and improving curing efficiency. The following is a further detailed description of this application.

[0040] Example

[0041] Reference Figure 1 The photovoltaic frame adhesive application and pressing system provided in this application includes a photovoltaic conveying mechanism 1, a frame preheating chamber 2, a frame conveying mechanism 3, a traveling track 4, a traveling trolley 41, a clamping mechanism 42, and an adhesive application mechanism 43. The frame preheating chamber 2 and the frame conveying mechanism 3 are located to the side of the photovoltaic conveying mechanism 1 in the conveying direction, with the middle of the frame conveying mechanism 3 passing through the frame preheating chamber 2 to preheat the frame during conveying. The traveling track 4 is located above the outlet of the frame preheating chamber 2, the traveling trolley 41 is mounted on the traveling track 4, and the clamping mechanism 42 and the adhesive application mechanism 43 are mounted on the traveling trolley 41. Preheating and applying adhesive to the frame before pressing the photovoltaic module promotes adhesive curing after pressing and improves curing efficiency. This is because preheating the frame allows the adhesive to be in a more favorable temperature environment for curing during pressing, and also allows the curing process to begin more quickly after adhesive application.

[0042] Specifically, the photovoltaic conveying mechanism 1 is used to transport photovoltaic modules, and it can be composed of a support frame and a conveyor belt 33. The support frame provides support and is usually made of metal, such as stainless steel or aluminum alloy, to ensure sufficient strength and stability. The conveyor belt 33 is mounted on the support frame to transport the photovoltaic modules. In addition to the common roller conveyor belt 33, a chain plate conveyor belt 33 can also be used, which has advantages such as high load-bearing capacity and long conveying distance.

[0043] Reference Figure 2The frame preheating chamber 2 includes a chamber body 21 and several heating tubes 22. The chamber body 21 is generally made of a material with good thermal insulation properties, such as polyurethane foam sandwich panels, to reduce heat loss. The heating tubes 22 are located inside the chamber body 21 and are used to generate heat to preheat the frame. The heating tubes 22 can be electric heating tubes 22, such as stainless steel electric heating tubes 22, which have the characteristics of high heating efficiency and long life. A temperature sensor can also be installed inside the chamber body 21 to monitor the temperature inside the chamber in real time, so as to better control the operation of the heating tubes 22 and ensure the stability of the preheating temperature. Alternatively, infrared heating or other methods can be used to replace the electric heating tubes 22. Infrared heating has the advantages of fast heating speed and good directionality.

[0044] Reference Figure 2 and Figure 3 The frame conveying mechanism 3 includes a conveyor frame 31, which is connected to the housing 21 to support the conveyor rollers 32. It is typically made of welded metal profiles. In this embodiment, two conveyor rollers 32 are rotatably mounted on the conveyor frame 31, and a conveyor belt 33 is wound around the outer sides of the two conveyor rollers 32. The conveyor frame 31 is also connected to a conveyor drive 34, which can be a motor that drives the conveyor rollers 32 to rotate via a chain, belt, or other transmission method, thereby driving the conveyor belt 33 to operate. Several support rollers 35 are also rotatably mounted inside the conveyor frame 31 and the conveyor belt 33. The diameter of the support rollers 35 is smaller than the diameter of the conveyor rollers 32, but the tops of the support rollers 35 are flush with the tops of the conveyor rollers 32. The support rollers 35 can be made of materials such as nylon, which have advantages such as good wear resistance and low noise. The function of the support rollers 35 is to support the middle of the conveyor belt 33, reducing the sagging of the conveyor belt 33 during conveying and ensuring the stability of the frame conveying. When the conveyor belt 33 is conveying the frame, the support roller 35 rotates with the conveyor belt 33, sharing part of the weight of the frame and making the force on the conveyor belt 33 more even.

[0045] Reference Figure 3 The number of conveyor belts 33 is two or more, and in this embodiment, there are three, with a heat-permeable gap 36 between adjacent conveyor belts 33. The presence of the heat-permeable gap 36 facilitates better transfer of heat generated by the heating pipe 22 to the frame, improving preheating efficiency. The size of the heat-permeable gap 36 can be adjusted according to actual conditions and designed as needed. The adjacent conveyor belts 33 run at the same speed, thereby ensuring the stability of the frame conveying.

[0046] Reference Figure 1 and Figure 4The traveling track 4 provides a running path for the traveling trolley 41. In this embodiment, the traveling track 4 can be made of I-beams or other profiles, which have good strength and rigidity. The traveling trolley 41 is mounted on the traveling track 4 and moves on the traveling track 4 via a motor, gears, or other drive devices. The traveling trolley 41 can have a steel frame structure with a powder-coated surface to improve corrosion resistance.

[0047] The clamping mechanism 42 and the glue-applying mechanism 43 are mounted on the traveling trolley 41. The clamping mechanism 42 is used to transfer the frame and can be composed of grippers 421, cylinders 422, etc. The grippers 421 are made of high-strength alloy steel and have sufficient clamping force. The cylinders 422 are used to drive the opening and closing of the grippers 421. In other embodiments, the clamping mechanism 42 can also be replaced by electric grippers 421, which has the advantages of high control precision and fast response speed.

[0048] The glue application mechanism 43 is used to apply glue to the frame. It can consist of a glue tank 431, a glue pump (not shown in the figure), and a spray gun 432. The glue tank 431 stores the glue, and the glue pump delivers the glue from the glue tank 431 to the spray gun 432, which then sprays the glue evenly onto the frame. The spray gun 432 of the glue application mechanism 43 can be an automatic spray gun, with the spraying amount and speed controlled by a program to ensure the quality of the glue application.

[0049] Reference Figure 5 In this embodiment, there are two walking tracks 4, each equipped with a corresponding walking trolley 41. A mounting plate 44 is connected between the two walking trolleys 41. A slide block 45 is slidably connected to the bottom of the mounting plate 44. In addition, the mounting plate 44 is also equipped with a moving mechanism 46 for driving the slide block 45 to slide. The moving mechanism 46 can be a screw and nut mechanism, driven by a motor to rotate the screw, thereby driving the nut and the slide block 45 to slide on the mounting plate 44.

[0050] The slide 45 is connected to the glue applicator 43 via the adjustment mechanism 47. The adjustment mechanism 47 can be an electric push rod. The height of the glue applicator 43 can be adjusted by controlling the extension and retraction of the electric push rod, so as to adjust the height as needed during the glue application, transfer or pressing of the frame.

[0051] Reference Figure 6An air supply mechanism 5 is installed below both sides of the photovoltaic conveying mechanism 1 along the conveying direction. The air supply mechanism 5 includes a housing 51, a heating wire 52, and a fan 53. The housing 51 is a vertically arranged cylindrical structure with openings at both ends, generally made of metal, such as galvanized steel plate, which has good strength and corrosion resistance. The housing 51 contains a heating wire 52, which can be a nickel-chromium alloy heating wire, characterized by high temperature resistance and high heating efficiency. The fan 53 is located at the bottom of the housing 51 and is used to draw air into the housing 51 from bottom to top. After being heated by the heating wire 52, it forms hot air, which is then blown upwards towards the pressing area between the photovoltaic module and the frame. The fan 53 can be a centrifugal fan, which has the advantages of large air volume and high air pressure. In addition, a protective mesh cover 54 is installed at the top opening of the housing 51. The protective mesh cover 54 can be made of stainless steel wire mesh to reduce the entry of debris into the housing 51 while ensuring that the hot air can be blown out smoothly. In other embodiments, an axial flow fan 53 or similar device can be used instead of a centrifugal fan 53. The axial flow fan 53 has advantages such as simple structure and low noise.

[0052] The implementation principle of this embodiment is as follows: The system combines the frame preheating chamber 2 with the frame conveying mechanism 3, the traveling track 4, and the clamping mechanism 42 and glue application mechanism 43 on the traveling trolley 41 to achieve the preheating and glue application operations of the frame. During the photovoltaic module transportation process, the frame enters the frame preheating chamber 2 for preheating under the drive of the frame conveying mechanism 3. After preheating, the frame is transferred to the photovoltaic module by the clamping mechanism 42 on the traveling trolley 41. At the same time, the glue application mechanism 43 applies glue to the frame, and then a pressing operation is performed. The support roller 35 can reduce the sagging of the conveyor belt 33 and ensure the smooth transportation of the frame; the heat transmission gap 36 is conducive to heat transfer and improves the preheating efficiency of the frame; the air supply mechanism 5 blows hot air to the pressing part to further promote the curing of the glue; the two traveling trolleys 41 and related structures increase the movement flexibility and adjustment range of the glue application mechanism 43. Because the frame is preheated and there are various measures to promote curing, the adhesive can cure faster after pressing. This avoids the inconvenience of transferring the photovoltaic module to the next process for heating and curing after pressing, which is a traditional method. This improves production efficiency and reduces production costs, and is an effective improvement on existing technology.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
