[0008] When the slider moves to the first extreme position toward the center of the barrel body, the fan-shaped guide plates are driven to close so that the side surfaces of adjacent fan-shaped guide plates are connected to form a closed conical cylinder; when the slider moves away from the center of the barrel body to the second extreme position, the fan-shaped guide plates are driven to unfold at the bottom of the barrel body.

[0009] In combination with the first aspect, in one achievable 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 combination with the first aspect, in one achievable manner, when the connecting rod is perpendicular to the linear guide rail, the angle a between the fan-shaped guide plate and the linear guide rail is ≥45° and is an acute angle.

[0011] In combination 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 polygonal cone; when the fan-shaped guide plate is an arc-shaped plate, the enclosed conical cylinder is a circular cone.

Then, for the same volume of silicone, the height will increase due to the reduction in cross-sectional area, thereby increasing the depth of the silicone, which makes it easier to suck out the silicone, thereby reducing the amount of silicone remaining in the silicone bag, achieving maximum utilization of the silicone, thereby improving the utilization rate of the silicone, reducing the phenomenon of silicone waste, and reducing the production cost of the battery.

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] After lamination and trimming, photovoltaic modules will be assembled using frames, and the gaps will be sealed with silicone. However, due to the existing glue-applying tooling, the silicone cannot be completely discharged. According to current experience, a barrel of 270kg of silicone will have about 6-10kg of silicone left, with a loss of 3%, and the material loss is very high. In order to reduce the loss of silicone and reduce resource waste, the present invention provides a silicone barrel that can improve the phenomenon of silicone waste and improve the utilization rate of silicone.

[0036] Please also read Figures 1 to 8 The silicone barrel provided by the present invention is now described. The silicone barrel comprises a barrel body 1 and an opening and closing storage mechanism 2, wherein the barrel body 1 is used to hold silicone bags; the opening and closing storage mechanism 2 comprises a plurality of fan-shaped guide plates 21 and an opening and closing driving 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 barrel body 1, and the fan-shaped guide plates 21 are evenly distributed in the circumferential direction of the bottom of the barrel body 1; the opening and closing driving assembly 22 is movably connected between the fan-shaped guide plate 21 and the bottom of the barrel body 1 to drive the fan-shaped guide plate 21 to open or close, thereby forming a conical barrel with different calibers.

[0037] The silica gel barrel provided by the present invention is provided with an opening and closing storage mechanism 2 at the bottom of the barrel body 1. Initially, the amount of silica gel in the silica gel bag is large. In order to avoid the fan-shaped guide plate 21 blocking the silica gel bag, the fan-shaped guide plate 21 is driven by the opening and closing driving component 22 to be flat or substantially flat. When the amount of silica gel is small, the height of the silica gel in the flat state in the barrel body 1 becomes lower and lower until the silica gel cannot be sucked up, the opening and closing driving component 22 is started 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 surrounded by the fan-shaped guide plate 21 gradually decreases, and the silica gel gradually gathers into the conical barrel. In addition, for the same volume of silica gel, the height will increase due to the reduction of the cross-sectional area, thereby increasing the depth of the silica gel, which is convenient for sucking out the silica gel, thereby reducing the amount of silica gel remaining in the silica gel bag, thereby improving the utilization rate of the silica gel, reducing the phenomenon of silica gel waste, and reducing the production cost of the battery.

[0038] The conical cylinder of the present application is a cone or a multi-sided pyramid. For example, the volume formula of a cone is: V = 1 / 3Sh, where S is the bottom area, h is the height, and r is the bottom radius. The bottom here refers to the area enclosed by the large circle of the cone. According to the volume formula of the cone, when the volume of the silica gel is constant, the smaller the bottom radius, the higher the height, and therefore the more conducive it is to suck out the silica gel.

[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 body 1 along the radial direction of the barrel body 1. One end of the connecting rod 221 is hinged to the back side 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 to the first extreme position toward the center of the barrel body 1, the fan-shaped guide plate 21 is driven to close so that the side surfaces of adjacent fan-shaped guide plates 21 are connected to form a closed conical cylinder. When the slider moves to the second extreme position away from the center of the barrel body 1, the fan-shaped guide plate 21 is driven to unfold at the bottom of the barrel body 1.

[0040] A hinge support 23 is provided at the bottom of the barrel body 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, and the fan-shaped guide plate 21 forms a closed-loop conical cylinder, that is, a complete and continuous cone or prism; when the slider moves to the second extreme position, the connecting rod 221 is parallel to the linear guide rail 222, and the barrel body 1 contains the maximum amount of silica gel.

[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 a 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 cylinder, and the higher the height of the formed conical cylinder. For example, a is 50°, 60°, 75°, etc.

[0043] In some embodiments, the fan-shaped guide plate 21 is a flat plate or an arc-shaped plate. When the fan-shaped guide plate 21 is a flat plate, the conical cylinder formed is a polygonal cone. Figure 5 When the fan-shaped guide plate 21 is an arc-shaped plate, the conical cylinder formed is a conical cylinder, see Figure 4 shown.

[0044] Among them, the present invention is provided with more than four 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 silica gel bag; of course, it also needs to be designed according to the diameter of the barrel body 1. If there are a large number of fan-shaped guide plates 21, the production will be more complicated, the installation will also be troublesome, 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 surface is in contact with the inner wall of the barrel body 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 body 1. When the fan-shaped guide plates 21 are unfolded at the bottom of the barrel body 1, the support platform 3 is located between the gaps between two adjacent fan-shaped guide plates 21, and together with the fan-shaped guide plates 21, it forms a support surface for supporting silica gel. In this way, when the fan-shaped guide plates 21 are unfolded, they can be connected with the support platform 3 to form a support plane for supporting silica gel bags, or a cone with a small angle, which can prevent the silica gel bags and silica gel from falling between the fan-shaped guide plates 21.

[0047] The supporting platform 3 is triangular in shape and fills the gaps between the fan-shaped guide plates 21 .

[0048] In some embodiments, the opening and closing drive assembly 22 includes an electric push rod (not shown in the figure), the main body of the electric push rod is hinged to the bottom of the barrel body 1, and the push rod of the electric push rod is hinged to the back of the fan-shaped guide plate 21. The extension and retraction of the electric push rod can also drive the fan-shaped guide plate 21 to close or expand, thereby achieving the purpose of 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. Because the weight on the fan-shaped guide plate 21 is applied by the remaining silicone, the weight of the remaining silicone and the height of the remaining silicone in the barrel body 1 can be judged, 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 description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0051] Based on the same inventive concept, an embodiment of the present application further provides an operation method for improving the utilization rate of silica gel, based on the silica gel barrel, the method comprises:

[0052] Step 1: Install the opening and closing storage mechanism 2 at the bottom of the barrel body 1, and the linear guide rail 222 drives the fan-shaped guide plate 21 to unfold;

[0053] Step 2: placing a silica gel bag containing silica gel in the barrel body 1, and the silica gel bag is supported on the fan-shaped guide plate 21;

[0054] Step 3: When the weight of the silica gel in the barrel body 1 is lower than the preset weight, the opening and closing driving component 22 is started to drive the fan-shaped guide plate 21 to close upward, so that the fan-shaped guide plate 21 forms a conical cylinder; here, it can also be determined whether to open the driving component according to the height of the silica gel in the barrel body 1 or the pressure on the fan-shaped guide plate 21;

[0055] Step 4: At the same time, the silica gel bag is lifted upward, and the lower end of the silica gel bag is kept to fit in the conical tube in a conical shape under the filling of silica gel, so that the silica gel is gathered in the conical tube;

[0056] Step 5: As the amount of silica gel decreases and the height of silica gel in the barrel body 1 decreases, the fan-shaped guide plate 21 is continuously driven to close upward until the fan-shaped guide plate 21 is closed into a closed conical cylinder;

[0057] Step six: As the cross-sectional area of ​​the conical tube decreases, the silica gel in the silica gel bag can maintain a certain depth at the same volume, so as to facilitate the suction of the silica gel and reduce the residual amount of silica gel.

[0058] Among them, the mechanism for lifting the silicone bag can be a lifting mechanism, and the lifting mechanism can be an electric push rod, a linear cylinder, a lifting screw, etc., which can lift the silicone bag by closing the fan-shaped guide plate 21 so that the lower end of the silicone bag is always within the encirclement of the fan-shaped guide plate 21.

[0059] In step 3, 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 in the protection scope of the present invention.
