Description

Technical Field

[0001] This utility model relates to the field of solar panel production, and in particular to a solar panel production adhesive coating device. Background Technology

[0002] Solar panel adhesive application equipment is a key piece of equipment in photovoltaic module production. It is used to precisely apply sealant or structural adhesive to the joints between the photovoltaic panel and the frame, laminated materials, etc., to ensure the module's sealing performance, structural stability, and long-term weather resistance. This equipment typically consists of a glue gun, a three-axis linkage robotic arm, a pressure control system, and a positioning module. Through automated control of the glue amount, path, and speed, it ensures that the adhesive layer evenly covers the joint area, effectively preventing delamination caused by moisture penetration, cell displacement, and environmental stress. It is a core process equipment for improving the efficiency and lifespan of photovoltaic modules.

[0003] In the prior art, compared to the Chinese utility model disclosure CN222267713U, which discloses a solar panel coating device, this device improves the coating effect by fixing the photovoltaic panel during the coating process. However, the design logic of such devices is still based on the static working condition assumption, that is, it is assumed that the adhesive only bears constant environmental stress after the coating is completed. In practical applications, photovoltaic modules will experience alternating stress concentration due to dynamic loads such as gravity, wind load, and thermal expansion during transportation, hoisting deformation, and long-term outdoor service. After the coating is applied, the photovoltaic module's own stress is concentrated and changed due to external factors such as gravity during transportation, hoisting, and use, causing misalignment between the frame and the photovoltaic panel, and cracking of the adhesive between the frame and the photovoltaic panel. Utility Model Content

[0004] The purpose of this invention is to provide a solar panel coating device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A solar panel manufacturing adhesive coating apparatus includes a conveying mechanism for conveying photovoltaic modules and a moving mechanism for adjusting the adhesive coating position. The moving mechanism is installed on the upper side of the photovoltaic modules. The apparatus also includes a support mechanism for supporting the frame during the adhesive coating process to fill gaps and an adjusting mechanism for adjusting the pressure of the support mechanism. The support mechanism is installed on the bottom side of the adhesive coating mechanism, the adhesive coating mechanism is installed at the movable end of the moving mechanism, and the adjusting mechanism is installed in the pressure adjusting part of the support mechanism.

[0007] The glue application mechanism includes a mounting frame, a glue applicator mounted at the bottom of the mounting frame, a rotating power component connected to the outside of the glue applicator, the glue applicator being rotatably connected to the mounting frame, an expansion frame fixed to the outside of the glue applicator, and a support mechanism fixed to one end face of the expansion frame.

[0008] The support mechanism includes a fixing member, a telescopic member slidably connected in the groove formed by the fixing member, a support wheel installed on the top of the telescopic member, and a pressure cylinder provided inside the fixing member, the pressure cylinder being interconnected with the adjustment mechanism.

[0009] Preferably, the adjusting mechanism includes an oil circuit connecting cylinder, which is connected to the pressure applying cylinder via an oil pipe. A pressure regulating cylinder is provided at the top of the oil circuit connecting cylinder. A lower pressure piston is provided inside the pressure regulating cylinder near the oil circuit connecting cylinder. An upper pressure piston is provided above the lower pressure piston. A storage spring is provided between the lower pressure piston and the upper pressure piston. A pressure regulating screw is rotatably connected to the top of the upper pressure piston. The top of the pressure regulating screw passes through the pressure regulating cylinder and is threadedly connected to the pressure regulating cylinder.

[0010] Preferably, there are two support wheels, and the outer end face of the support wheel is an arc surface. The support wheel is made of hard rubber.

[0011] This configuration utilizes the support wheels to support the frame of the photovoltaic module, allowing the adhesive to be applied into the gap between the photovoltaic panel and the frame during the gluing process. This eliminates misalignment caused by stress deformation later on, thus preventing the adhesive from coming off later.

[0012] Preferably, there are two pressure cylinders, which are respectively located on both sides of the oil circuit connecting cylinder.

[0013] This configuration utilizes two pressure cylinders to ensure smooth retraction of the telescopic component.

[0014] Preferably, the oil chambers of the two pressure cylinders and the oil circuit connecting cylinder are interconnected.

[0015] With this configuration, the oil chambers between the two pressure cylinders and the oil circuit connecting cylinder are interconnected. When the oil circuit is compressed, the oil pressure on both sides can be balanced, thereby ensuring that the telescopic component and the support wheel retract smoothly during contraction.

[0016] Preferably, the fastener is installed at an angle on the expansion frame, and the angle range is 30°-60°.

[0017] Preferably, the fastener is connected to the expansion frame by bolts, and the expansion frame is formed with a sliding groove that matches the adjustment position of the fastener.

[0018] Compared with existing technologies, the beneficial effects are as follows:

[0019] The frame of the photovoltaic module is supported by a support mechanism. This is to address the issue that the photovoltaic module is laid flat during the adhesive application process, but during transportation, hoisting, and use, the stress of the photovoltaic module itself is concentrated and changed by external factors such as gravity, which can cause misalignment between the frame and the photovoltaic panel. The mechanism provides reverse stress in advance to apply adhesive to the internal gaps and prevent cracking problems later. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1-6 As shown, a solar panel production adhesive coating device includes a conveying mechanism 1 for conveying a photovoltaic module 2 and a moving mechanism 3 for adjusting the adhesive coating position. The moving mechanism 3 is installed on the upper side of the photovoltaic module 2. It also includes a support mechanism 5 for supporting the frame during the adhesive coating process to fill gaps and an adjusting mechanism 6 for adjusting the pressure of the support mechanism 5. The support mechanism 5 is installed on the bottom side of the adhesive coating mechanism 4. The adhesive coating mechanism 4 is installed on the movable end of the moving mechanism 3. The adjusting mechanism 6 is installed on the pressure adjusting part of the support mechanism 5.

[0032] The glue application mechanism 4 includes a mounting frame 41, a glue applicator 43 is mounted on the bottom of the mounting frame 41, a rotating power component 45 is externally connected to the glue applicator 43, the glue applicator 43 is rotatably connected to the mounting frame 41, an expansion frame 42 is fixedly connected to the outside of the glue applicator 43, and a support mechanism 5 is fixedly connected to one end face of the expansion frame 42.

[0033] The support mechanism 5 includes a fixing member 51, a telescopic member 52 which is slidably connected in the groove formed by the fixing member 51, a support wheel 53 is installed on the top of the telescopic member 52, and a pressure cylinder 54 is provided inside the fixing member 51. The pressure cylinder 54 is interconnected with the adjustment mechanism 6.

[0034] In this embodiment, the adjusting mechanism 6 includes an oil circuit connecting cylinder 61, which is connected to a pressure applying cylinder 54 via an oil pipe. A pressure regulating cylinder 62 is provided at the top of the oil circuit connecting cylinder 61. A lower pressure piston 64 is provided inside the pressure regulating cylinder 62 near the side of the oil circuit connecting cylinder 61. An upper pressure piston 65 is provided on the upper side of the lower pressure piston 64. A storage spring 66 is provided between the lower pressure piston 64 and the upper pressure piston 65. A pressure regulating screw 63 is rotatably connected to the top of the upper pressure piston 65. The top of the pressure regulating screw 63 passes through the pressure regulating cylinder 62 and is threadedly connected to the pressure regulating cylinder 62.

[0035] In this embodiment, two support wheels 53 are provided, and the outer circular end face is arc surface. The support wheels 53 are made of hard rubber. The support wheels 53 are used to support the frame of the photovoltaic module 2, so that the glue is applied into the gap between the photovoltaic panel and the frame during glue application, eliminating the misalignment caused by stress deformation in the later stage, thereby avoiding the situation of glue delamination in the later stage.

[0036] In this embodiment, two pressure cylinders 54 are provided, and they are respectively located on both sides of the oil circuit connecting cylinder 61. The two pressure cylinders 54 are used to ensure that the telescopic member 52 can be retracted smoothly.

[0037] In this embodiment, the oil chambers between the two pressure cylinders 54 and the oil circuit connecting cylinder 61 are interconnected. When the oil circuit is compressed, the oil pressure on both sides can be balanced, thereby ensuring that the telescopic member 52 and the support wheel 53 retract smoothly during contraction.

[0038] In this embodiment, the fastener 51 is installed at an angle on the expansion frame 42, and the angle range is 30°-60°.

[0039] In this embodiment, the fixing member 51 is connected to the expansion frame 42 by bolts, and the expansion frame 42 is formed with a sliding groove that matches the fixing member 51 to adjust the position.

[0040] Working principle: Before use, adjust the position of the glue applicator 43 spray group and the angle and height of the support wheel 53 according to the size and height of the frame, so that the glue spraying position and the support position are matched. In addition, it is necessary to select an appropriate stress deformation range according to the frame material, and then adjust the position of the pressure adjusting screw 63 to provide initial pressure to the storage spring 66.

[0041] After the equipment is started, the moving mechanism 3 drives the glue application mechanism 4 and the support mechanism 5 to move. At this time, the support wheel 53 will first contact the side of the frame. Figure 3 As shown, the frame will be subjected to pressure deformation, causing the gap between the photovoltaic panel and the frame to widen. At this time, the glue applicator 43 sprays glue to fill the gap between the frame and the photovoltaic panel, and can fill the enlarged gap. The moving mechanism 3 continues to move, and after the movement, the frame loses pressure, the frame resets, and the gap is compacted by the reset frame.

[0042] During the pressure application process of the support wheel 53, the support wheel 53 and the telescopic component 52 will be subjected to reverse pressure to lock the inside of the fixing component 51. Then the pressure cylinder 54 is compressed, and the oil is forced into the oil circuit connecting cylinder 61. The downward pressure piston 64 in the pressure regulating cylinder 62 is supported by the storage spring 66 and provides downward pressure, which makes the support wheel 53 supported. Because the oil has damping, the change process is relatively stable and there will be no large shaking, thus avoiding large shaking of the frame and affecting the glue application efficiency.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
