Description

Technical Field

[0001] The utility model relates to the field of glue potting machine clamps, in particular to a glue potting clamp used for a photovoltaic junction box. Background Art

[0002] When the glue dispensing machine is working, the glue is first loaded into the glue storage tank of the glue dispensing machine, and the glue dispensing parameters are set through the control system. During the glue dispensing process, the control system issues a command, and the mechanical system presses out the glue through air pressure or electric means, and accurately injects the glue into the product through the robotic arm and injection head. After the glue dispensing is completed, the product enters the curing stage, and the glue solidifies under specific conditions to form the required sealing or fixing effect. When the existing glue dispensing machine is used, the photovoltaic junction box does not have a fixed position and is generally fixed in one place for glue dispensing. The glue dispensing fixture used is generally complex in structure and the positioning is not accurate enough. If it is not placed in place, it will lead to glue dispensing failure, and the work efficiency and yield rate cannot be guaranteed. Now there is an urgent need for a glue dispensing fixture for photovoltaic junction boxes that is easy to operate and has precise positioning to ensure the quality of glue dispensing, improve the work efficiency of the glue dispensing machine, and ensure the accuracy of glue dispensing and the completion of the curing rate.

[0016] In the following embodiments, it should be noted that the terms "up", "down", "left", "right", "inside", "outside", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of clearly describing the present embodiment, and do not indicate or imply that the device or element referred to must have a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0017] like Figure 1-2As shown, the specific embodiment of the present invention is: a glue filling fixture for a photovoltaic junction box 11, including a fixed base plate 1 for carrying the fixture and fixing the fixture, a rear baffle 2 is fixedly installed at one end of the fixed base plate 1 by screws, and a slightly raised cylindrical block-shaped limiting boss 3 is provided on each of the left and right sides of the fixed base plate 1, and two concave platforms 4 are provided between the limiting bosses 3 (the concave platforms are composed of two raised cylindrical blocks), a left limiting plate 5 is provided next to the limiting boss 3 on the left side of the fixed base plate 1, a right limiting plate 6 is provided next to the limiting boss 3 on the right side of the fixed base plate 1, and a middle limiting plate 7 is provided on the concave platform 4 in the middle of the fixed base plate 1; wherein the left limiting plate 5 and the right limiting plate 6 are both provided with a guide wing plate 8 on one side of the upper part, and guide wing plates 8 are provided on the left and right sides of the upper part of the middle limiting plate 7. The guide wing plates 8 can guide the insertion and installation of the photovoltaic junction box 11, and can stabilize the photovoltaic junction box 11 under the guide wing plates 8 after the insertion is completed.

[0018] In order to better limit the storage of the photovoltaic junction box, the ends of the left limit plate 5, the right limit plate 6, and the middle limit plate 7 are all in contact with the surface of the rear baffle 2, and the bottoms of the left limit plate 5, the right limit plate 6, and the middle limit plate 7 are connected to the fixed base plate 1, and the fixed base plate 1 is connected to the rear baffle 2, thus forming a stable fixed cavity that can just accommodate the photovoltaic junction box 11.

[0019] To facilitate further precise positioning during the glue pouring process, U-shaped fixing blocks 9 are also installed on the top of the left limit plate 5, right limit plate 6, and center limit plate 7. After the robot reaches the designated glue injection hole of the photovoltaic junction box during the glue pouring process, the U-shaped fixing blocks provide mechanical positioning or limiting, further improving the glue pouring accuracy.

[0020] In order to fix the clamp of the present invention to the glue filling machine, two fixing holes 10 for fixing it to the glue filling machine are respectively provided on both sides of the fixed base plate 1, and fixing holes 10 are provided at the bottom of the left limit plate 5, the right limit plate 6 and the middle limit plate 7. The clamp can be stably connected to the glue filling machine through the fixing holes 10 using screws and other connecting parts.

[0021] To facilitate the fixing of the photovoltaic junction box 11, the left limit plate 5, the right limit plate 6 and the middle limit plate 7 are configured as stepped block structures. The end of the guide wing plate 8 away from the rear baffle 2 is a trapezoidal structure, and the guide wing plate 8 forms a flared structure with the fixed base plate 1.

[0022] When in use, first fasten the fixed base plate 1 to the glue filling machine with screws, then install the left limit plate 5, right limit plate 6 and middle limit plate 7 in the appropriate position of the fixed base plate 1 according to the size of the photovoltaic junction box 11, then connect the rear baffle 2 to the fixed base plate 1 and install it, and the ends of the rear baffle 2 and the left limit plate 5, right limit plate 6 and middle limit plate 7 are all in contact with the surface of the rear baffle 2, and then fix the U-shaped fixing block 9 on the top of the left limit plate 5, right limit plate 6 and middle limit plate 7. After the glue filling fixture is installed, place the photovoltaic junction box 11 into the concave platform 4 formed between the limit plates and fix the photovoltaic junction box 11. The junction box mounting fixture is used to fix the photovoltaic junction box 11, ensuring that the photovoltaic junction box 11 will not move during the glue filling process, ensuring the accuracy and quality of the glue filling. During the glue filling process, the glue filling machine is turned on, and the glue filling fixture can accurately move the glue filling head to the position where glue filling is required for glue filling, ensuring the accuracy of the glue filling. This glue potting fixture is widely used in the glue potting process of electronic components that need to be accurately fixed and sealed.

[0023] Through the above steps and design features, the glue filling fixture for photovoltaic junction boxes of the present invention can effectively improve the quality and efficiency of the glue filling operation, ensure the stability and reliability of the junction box, and is easy to assemble and disassemble, has certain versatility and better adaptability. If you encounter junction boxes of different sizes, you only need to replace the substrate of the corresponding size, and the other parts have certain versatility; at the same time, since the glue filling process may be in a vacuum-sealed environment, and the closed environment has solvent volatilization, the glue filling fixture of this application is made of metal, preferably stainless steel, and the versatility of this application is strong, which can further reduce the cost of use.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements and improvements made to the above embodiments based on the technical essence of the present invention should be included in the scope of protection of the technical solution of the present invention.
