Abstract
Description
Technical Field
[0001] This invention belongs to the field of photovoltaic module manufacturing technology, specifically relating to a silicone bucket and an operation method for improving silicone utilization. Background Technology
[0002] Silicone is an indispensable adhesive for bonding photovoltaic cell modules and junction boxes. The silicone is packaged in bags and placed in a container, then absorbed by a glue applicator. However, the following problems arise during use: the glue applicator typically cannot remove all the silicone from the container, leaving silicone residue at the bottom. This residual silicone cannot be used directly by the applicator, resulting in significant waste and impacting the production cost of photovoltaic modules. Summary of the Invention
[0003] This invention provides a silicone bucket and an operating method for improving silicone utilization, aiming to increase silicone utilization and reduce the production cost of photovoltaic modules.
[0004] Firstly, to achieve the above objectives, the technical solution adopted by the present invention is: to provide a silicone bucket, comprising:
[0005] The container body is used to hold silicone bags; and
[0006] The opening and closing storage mechanism includes multiple fan-shaped guide plates and corresponding opening and closing drive components for each fan-shaped guide plate; the small end of each fan-shaped guide plate is hinged to the bottom of the barrel body, and the fan-shaped guide plates are evenly distributed in the circumferential direction at the bottom of the barrel body; the opening and closing drive components are movably connected between the fan-shaped guide plates and the bottom of the barrel body to drive the fan-shaped guide plates to open or close, forming conical cylinders of different diameters.
[0007] In conjunction with the first aspect, in one feasible manner, the opening and closing drive assembly includes a linear guide rail and a connecting rod, the linear guide rail being fixed radially to the bottom of the barrel, one end of the connecting rod being hinged to the back of the fan-shaped guide plate, and the other end of the connecting rod being hinged to the slider of the linear guide rail;
[0008] When the slider moves toward the center of the barrel to the first extreme position, it causes the fan-shaped guide plates to close, so that the sides of the adjacent fan-shaped guide plates connect to form a closed cone; when the slider moves away from the center of the barrel to the second extreme position, it causes the fan-shaped guide plates to unfold at the bottom of the barrel.
[0009] In conjunction with the first aspect, in one feasible manner, when the slider moves to the first extreme position, the connecting rod is perpendicular to the linear guide rail; when the slider moves to the second extreme position, the connecting rod is parallel to the linear guide rail.
[0010] In conjunction with the first aspect, in one feasible manner, when the connecting rod is perpendicular to the linear guide rail, the included angle α between the fan-shaped guide plate and the linear guide rail is ≥45° and is an acute angle.
[0011] In conjunction with the first aspect, in one feasible manner, the fan-shaped guide plate is a flat plate or an arc-shaped plate. When the fan-shaped guide plate is a flat plate, the enclosed conical cylinder is a multi-faceted pyramid; when the fan-shaped guide plate is an arc-shaped plate, the enclosed conical cylinder is a cylindrical cone.
[0012] In conjunction with the first aspect, in one feasible manner, when the fan-shaped guide vane is in the deployed state, its large end face is in contact with the inner wall of the barrel.
[0013] In conjunction with the first aspect, in one feasible manner, a support platform is also provided at the bottom of the barrel. When the fan-shaped guide plate is unfolded at the bottom of the barrel, the support platform is located in the gap between two adjacent fan-shaped guide plates, and together with the fan-shaped guide plate, forms a support surface for supporting the silicone.
[0014] In conjunction with the first aspect, in one feasible manner, the opening and closing drive assembly includes an electric actuator, the main body of which is hinged to the bottom of the barrel, and the push rod of which is hinged to the back of the fan-shaped guide plate.
[0015] In conjunction with the first aspect, in one feasible manner, a pressure sensor is disposed on the back side of the fan-shaped guide vane.
[0016] Secondly, embodiments of the present invention also provide an operation method for improving the utilization rate of silicone, based on the aforementioned silicone bucket, the method comprising:
[0017] The opening and closing storage mechanism is installed at the bottom of the barrel, and the linear guide rail drives the fan-shaped guide plate to unfold.
[0018] Place a silicone bag containing silicone into the barrel, and simultaneously support the silicone bag on the fan-shaped guide plate.
[0019] When the weight of the silicone inside the barrel is lower than the preset weight, the opening and closing drive assembly is activated, driving the fan-shaped guide plate to close upwards, so that the fan-shaped guide plate forms a cone-shaped cylinder.
[0020] At the same time, the silicone bag is lifted upwards, keeping the lower end of the silicone bag in a conical shape under the filling of silicone, so that the silicone gathers in the conical cylinder;
[0021] As the amount of silica gel decreases and the height of the silica gel inside the barrel decreases, the fan-shaped guide plate continues to be driven to close upwards until the fan-shaped guide plate closes into a closed conical cylinder.
[0022] As the cross-sectional area of the conical tube decreases, the silicone inside the silicone bag can maintain a certain depth for the same volume, which facilitates the extraction of silicone and reduces the amount of silicone remaining.
[0023] Compared with the prior art, the silicone bucket provided by this invention has the following advantages: An opening and closing storage mechanism is set at the bottom of the bucket. Initially, when the amount of silicone in the silicone bag is large, to avoid the fan-shaped guide plate blocking the silicone bag, the fan-shaped guide plate is driven by the opening and closing drive assembly to be in a flat or nearly flat state. When the amount of silicone is small, the height of the silicone in the flat state inside the bucket gradually decreases until it can no longer be sucked up. At this point, the opening and closing drive assembly is activated to drive the fan-shaped guide plate to rotate upwards, causing the angle between the fan-shaped guide plate and the linear guide rail to gradually increase. The cross-sectional area of the conical cylinder formed by the fan-shaped guide plate gradually decreases. Therefore, for the same volume of silicone, the height increases due to the reduced cross-sectional area, resulting in a greater depth of silicone. This facilitates the suction of silicone, thus reducing the amount of remaining silicone in the silicone bag, maximizing the utilization of silicone, improving the utilization rate of silicone, reducing silicone waste, and lowering the production cost of batteries.

[0034] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0035] After lamination and trimming, photovoltaic modules are assembled using frames, and the gaps are sealed with silicone. However, due to existing adhesive application equipment, the silicone cannot be completely discharged. Based on current experience, a 270kg bucket of silicone typically yields only 6-10kg of silicone remaining, representing a loss of about 3%, which is very high. To reduce silicone loss and resource waste, this invention provides a silicone bucket that improves silicone utilization and reduces waste.
[0036] Please refer to the following: Figures 1 to 8 The silicone bucket provided by the present invention will now be described. The silicone bucket includes a bucket body 1 and an opening and closing storage mechanism 2. The bucket body 1 is used to hold silicone bags. The opening and closing storage mechanism 2 includes a plurality of fan-shaped guide plates 21 and an opening and closing drive assembly 22 corresponding to each fan-shaped guide plate 21. The small end of the fan-shaped guide plate 21 is hinged to the bottom of the bucket body 1, and the fan-shaped guide plates 21 are evenly distributed in the circumferential direction of the bottom of the bucket body 1. The opening and closing drive assembly 22 is movably connected between the fan-shaped guide plates 21 and the bottom of the bucket body 1 to drive the fan-shaped guide plates 21 to open or close, forming conical cylinders of different diameters.
[0037] The silicone bucket provided by this invention has an opening and closing storage mechanism 2 at the bottom of the bucket body 1. Initially, when the amount of silicone in the silicone bag is large, to avoid the fan-shaped guide plate 21 blocking the silicone bag, the fan-shaped guide plate 21 is driven by the opening and closing drive assembly 22 to be in a flat or basically flat state. When the amount of silicone is small, the height of the silicone in the flat state inside the bucket body 1 becomes lower and lower until it can no longer be sucked up. At this time, the opening and closing drive assembly 22 is activated to drive the fan-shaped guide plate 21 to rotate upward, so that the angle between the fan-shaped guide plate 21 and the linear guide rail 222 gradually increases. The cross-sectional area of the conical cylinder formed by the fan-shaped guide plate 21 gradually decreases, and the silicone gradually gathers into the conical cylinder. For the same volume of silicone, the height will increase due to the decrease in cross-sectional area, thereby increasing the depth of the silicone. This makes it easier to suck out the silicone, thus reducing the amount of silicone remaining in the silicone bag, thereby improving the utilization rate of silicone, reducing silicone waste, and also reducing the production cost of batteries.
[0038] The conical cylinder of this application is a cone or a frustum of polygons. For example, the volume formula for a cone is: V = 1 / 3Sh, where S is the base area, h is the height, and r is the radius of the base. Here, the base refers to the area enclosed by the great circle of the cone. According to the volume formula for a cone, when the volume of the silicone is constant, the smaller the radius of the base and the higher the height, the more favorable it is for silicone extraction.
[0039] In some embodiments, see Figures 1 to 8 As shown, the opening and closing drive assembly 22 includes a linear guide rail 222 and a connecting rod 221. The linear guide rail 222 is fixed to the bottom of the barrel 1 along the radial direction of the barrel 1. One end of the connecting rod 221 is hinged to the back of the fan-shaped guide plate 21, and the other end of the connecting rod 221 is hinged to the slider of the linear guide rail 222. When the slider moves towards the center of the barrel 1 to the first limit position, it drives the fan-shaped guide plate 21 to close, so that the sides of the adjacent fan-shaped guide plates 21 are connected to form a closed cone. When the slider moves away from the center of the barrel 1 to the second limit position, it drives the fan-shaped guide plate 21 to unfold at the bottom of the barrel 1.
[0040] A hinge support 23 is provided at the bottom of the barrel 1, and the fan-shaped guide plate 21 is rotatably connected to the hinge support 23 via a rotating shaft.
[0041] In some embodiments, see Figures 1 to 8 As shown, when the slider moves to the first extreme position, the connecting rod 221 is perpendicular to the linear guide rail 222. At this time, the fan-shaped guide plate 21 forms a closed-loop conical cylinder, which is a complete and continuous cone or frustum. When the slider moves to the second extreme position, the connecting rod 221 is parallel to the linear guide rail 222. At this time, the barrel 1 can hold the maximum amount of silicone.
[0042] In some embodiments, see Figures 1 to 8 As shown, when the connecting rod 221 is perpendicular to the linear guide rail 222, the angle α between the fan-shaped guide plate 21 and the linear guide rail 222 is ≥45° and is an acute angle. The larger the angle between the fan-shaped guide plate 21 and the linear guide rail 222, the smaller the cross-sectional area of the formed conical tube, and the higher the height of the formed conical tube. For example, α is 50°, 60°, 75°, etc.
[0043] In some embodiments, the fan-shaped guide vane 21 is a flat plate or an arc-shaped plate. When the fan-shaped guide vane 21 is a flat plate, the enclosed conical cylinder is a multi-faceted pyramid. See [reference needed]. Figure 5 As shown; when the fan-shaped guide plate 21 is an arc-shaped plate, the enclosed conical cylinder is a cylindrical cylinder, see [reference]. Figure 4 As shown.
[0044] The present invention is provided with four or more fan-shaped guide plates 21, which can be five, six, seven or eight fan-shaped guide plates 21; the more fan-shaped guide plates 21 are provided, the easier it is to adjust the silicone bag; of course, it also needs to be designed according to the diameter of the barrel 1. The more fan-shaped guide plates 21 there are, the more complicated the production is, the more troublesome the installation is, and the production cost will also increase.
[0045] In some embodiments, see Figure 4 and Figure 5 As shown, when the fan-shaped guide plate 21 is in the unfolded state, its large end face is in contact with the inner wall of the barrel 1.
[0046] In some embodiments, see Figure 4 and Figure 5 As shown, a support platform 3 is also provided at the bottom of the barrel 1. When the fan-shaped guide plates 21 are unfolded at the bottom of the barrel 1, the support platform 3 is located between two adjacent fan-shaped guide plates 21, and together with the fan-shaped guide plates 21, forms a support surface for supporting the silicone. In this unfolded state, the fan-shaped guide plates 21 can connect with the support platform 3 to form a support plane for supporting the silicone bag, or a cone with a small angle, which can prevent the silicone bag and silicone from falling between the fan-shaped guide plates 21.
[0047] The support platform 3 is triangular in shape and fills the gap between the fan-shaped guide plates 21.
[0048] In some embodiments, the opening / closing drive assembly 22 includes an electric actuator (not shown in the figure), the main body of which is hinged to the bottom of the barrel 1, and the push rod of which is hinged to the back of the fan-shaped guide plate 21. The extension and retraction of the electric actuator can also drive the fan-shaped guide plate 21 to close or open, thereby changing the cross-sectional area of the conical cylinder.
[0049] In some embodiments, a pressure sensor (not shown in the figure) is provided on the back of the fan-shaped guide plate 21 to detect the weight borne on the fan-shaped guide plate 21. Since the weight on the fan-shaped guide plate 21 is applied by the remaining silicone, it is possible to determine the weight of the remaining silicone and the height of the remaining silicone in the barrel 1, thereby determining whether to open the opening and closing drive assembly 22 and whether to drive the fan-shaped guide plate 21 to flip upward.
[0050] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.
[0051] Based on the same inventive concept, this application also provides an embodiment of the present invention that provides an operation method for improving the utilization rate of silicone, based on the silicone bucket, the method comprising:
[0052] Step 1: Install the opening and closing storage mechanism 2 at the bottom of the barrel 1, and the linear guide rail 222 drives the fan-shaped guide plate 21 to unfold.
[0053] Step 2: Place the silicone bag containing silicone into the barrel 1, while the silicone bag is supported on the fan-shaped guide plate 21.
[0054] Step 3: When the weight of the silicone in the barrel 1 is lower than the preset weight, the opening and closing drive assembly 22 is activated, driving the fan-shaped guide plate 21 to close upwards, so that the fan-shaped guide plate 21 forms a conical cylinder; here, it is also possible to determine whether to activate the drive assembly based on the height of the silicone in the barrel 1 or the pressure on the fan-shaped guide plate 21.
[0055] Step four: Simultaneously, lift the silicone bag upwards, keeping the lower end of the silicone bag in a conical shape under the filling of silicone, so that the silicone gathers in the conical cylinder;
[0056] Step 5: As the amount of silicone decreases and the height of the silicone inside the barrel 1 decreases, the fan-shaped guide plate 21 continues to be driven to close upwards until the fan-shaped guide plate 21 closes into a closed cone.
[0057] Step six: As the cross-sectional area of the conical tube decreases, the silicone in the silicone bag can maintain a certain depth within the same volume, which facilitates the extraction of silicone and reduces the amount of silicone remaining.
[0058] The mechanism for lifting the silicone bag can be a lifting mechanism, such as an electric push rod, a linear cylinder, or a lifting screw. This mechanism works in conjunction with the closing of the fan-shaped guide plate 21 to lift the silicone bag, ensuring that the lower end of the silicone bag is always within the enclosure of the fan-shaped guide plate 21.
[0059] In step three, the preset weight is set to 6-10kg.
[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
