[0031] In the photovoltaic field, during the encapsulation process of solar cell modules, tin-plated copper materials are usually used to play a role in conducting and draining current in the solar cell modules. In order to achieve better welding effects, a large amount of flux is used during processing. The flux is generally stored in a barrel, and the flux barrel needs to be tilted when adding flux to the flux tank. The flux barrel is relatively heavy, and it is time-consuming and laborious to lift it manually. Moreover, the opening of the flux tank is relatively small, and spillage is likely to occur during the tilting process, resulting in waste; and the flux uses organic solvents as solvents, and other organic acids, halogen salts, etc. are dissolved in the solvent as active substances. When it spills on the ground or volatilizes into gas when exposed to the air, it will cause certain discomfort to the body.

[0032] Based on this, this application provides a flux storage device that can solve the above problems. The following will combine the drawings to introduce in detail the flux storage device provided by an embodiment of this application.

[0033] Refer to Figures 1 to 3As shown in the figure, a flux holding device 100 provided by an embodiment of the present application includes a holding container 110 and a cover body 120 detachably connected to the holding container 110; the holding container 110 has a cavity 111 for holding flux; the cover body 120 is used to close the cavity 111 to ensure the sealing effect of the flux in the cavity 111; an air inlet channel 121 and a liquid outlet channel 122 are provided on the cover body 120, the liquid outlet channel 122 is used to connect to a container to be refilled, the air inlet channel 121 is used to connect to a gas supply device, and the gas supply device is used to supply gas into the cavity 111 so that the pressure in the cavity 111 is greater than the pressure of the container to be refilled, so as to press the flux in the cavity 111 into the container to be refilled through the liquid outlet channel 122.

[0034] For the above flux holding device 100, by providing the air inlet channel 121 and the liquid outlet channel 122 on the cover body 120, when it is necessary to add flux to the container to be refilled, it is connected to the container to be refilled through the liquid outlet channel 122. For example, the liquid outlet channel 122 is communicated with the container to be refilled through a connecting pipe, and then the air inlet channel 121 is connected to the gas supply device, so that the pressure in the cavity 111 of the flux holding device 100 increases, and then the pressure in the cavity 111 is greater than the pressure of the container to be refilled. The pressure difference between the two enables the flux to automatically flow into the container to be refilled. It is not necessary to lift the flux holding container 110 to a certain height, and the liquid replenishment operation can be completed on the ground. The operation method is more convenient and efficient, reducing the operation difficulty and improving the replenishment efficiency at the same time. The flux is introduced into the container to be refilled through the liquid outlet channel 122, and the replenishment flow rate is relatively uniform, not easy to cause spillage, reducing the possibility of flux waste, and can avoid the discomfort caused by the spillage and volatilization to the human body, improving the safety performance of the operator.

[0035] In some embodiments, since the flux is corrosive, components such as the holding container 110 and the cover body 120 can be made of stainless steel. Stainless steel has good corrosion resistance and can better meet the requirements for holding flux. On the premise of not affecting the normal operation of the device for adding flux, in other embodiments, the holding container 110 and the cover body 120 can also be made of other corrosion-resistant materials.

[0036] In some embodiments, a liquid outlet pipe (not shown in the figure) is connected to the liquid outlet channel 122. The liquid outlet pipe is used to communicate with the container to be refilled. Through the arrangement of the liquid outlet channel 122 and the liquid outlet pipe, the flux in the cavity 111 is introduced into the container to be refilled, reducing the possibility of leakage. Further, a control valve (not shown in the figure) may be provided on the liquid outlet pipe to control the conduction and disconnection of the liquid outlet pipe. When the control valve is opened to make the liquid outlet pipe conductive, the flux can pass through the liquid outlet pipe into the container to be refilled; when the control valve is closed to make the liquid outlet pipe non-conductive, the refilling operation stops. By setting the control valve, the start and stop of the flux addition process can be better controlled, reducing the possibility of accidental spillage of the flux and further ensuring the smooth progress of the addition process.

[0037] In some embodiments, a check valve (not shown in the figure) is provided in the liquid outlet pipe. The setting of the check valve enables the flux to only flow from the storage container 110 into the container to be refilled, and will not flow in the reverse direction, ensuring the reliability of the refilling operation.

[0038] Refer to Figure 4 As shown, in one of the embodiments, an air inlet joint is connected to the cover body 120. The air inlet joint is configured with an air inlet through hole, and the air inlet through hole forms the air inlet channel 121. By providing the air inlet joint, it is convenient for the cover body 120 to be quickly connected to the air supply device, and the connection effect and sealing effect between the two can be ensured, ensuring the reliability of the air supply, and reducing the possibility of external impurities entering the cavity 111 and contaminating the flux, making the quality of the flux more reliably guaranteed. Among them, the air inlet joint can be integrally formed with the cover body 120 or welded to the cover body 120, etc.

[0039] Refer to Figure 4 As shown, in one of the embodiments, a liquid outlet joint is connected to the cover body 120. The liquid outlet joint is configured with a liquid outlet through hole, and the liquid outlet through hole forms the liquid outlet channel 122. By providing the liquid outlet joint, it is convenient for the cover body 120 to be quickly connected to the container to be refilled, and the connection effect and sealing effect between the two can be ensured, ensuring the reliability of the refilling and reducing the possibility of leakage. Among them, the liquid outlet joint can be integrally formed with the cover body 120 or welded to the cover body 120, etc.

[0040] Refer to Figure 4 As shown, in one of the embodiments, the air inlet channel 121 and the liquid outlet channel 122 are arranged at intervals. By arranging the air inlet channel 121 and the liquid outlet channel 122 at intervals, it is convenient to connect the air inlet channel 121 to the air supply device through a connecting pipe, and to connect the liquid outlet channel 122 to the container to be refilled through a connecting pipe, reducing the possibility of interference and entanglement of the connecting pipes, and further ensuring the reliability of the refilling.

[0041] Refer to Figure 4As shown, in one embodiment, the flow cross-sectional areas of the intake channel 121 and the liquid outlet channel 122 are different. Specifically, the cross-sectional area of the intake channel 121 is larger than that of the liquid outlet channel 122. With this arrangement, on the one hand, the reliability of the pressure increase in the cavity 111 can be ensured, and on the other hand, a certain flow rate of the flux can be ensured, thereby ensuring the smoothness of the liquid replenishment operation.

[0042] Refer to Figure 4 As shown, in one embodiment, a pressure gauge 123 for detecting the pressure in the cavity 111 is installed on the cover 120. Further, a pressure regulating valve can also be provided on the cover 120. In this way, the pressure gauge 123 can display the pressure in the cavity 111, so that the pressure in the cavity 111 can be automatically or manually adjusted through the pressure regulating valve later to ensure the safety and reliability during use. The above pressure gauge 123 can use an existing vacuum pressure gauge 123, and the above pressure regulating valve can use an existing gas pressure regulating valve.

[0043] In another embodiment, an exhaust valve (not shown in the figure) and a safety valve (not shown in the figure) are also installed on the cover 120. In this way, when the exhaust valve is opened, the cavity 111 can be connected to the external atmosphere, playing a role in rapid pressure relief, so as to open the cavity 111 for pouring later; and the safety valve can automatically relieve pressure when the pressure in the cavity 111 exceeds the safe range, avoiding accidents such as explosion when the pressure in the cavity 111 exceeds the limit, thereby ensuring the use safety of the flux storage device 100.

[0044] Refer to Figure 4 As shown, in one embodiment, in order to more clearly and accurately determine the remaining amount of the flux in the storage container 110 and the addition amount added to the container to be replenished with liquid, a liquid level gauge 112 for measuring the liquid level height is provided in the cavity 111 of the storage container 110. By providing a liquid level gauge 112 for measuring the liquid level height of the flux in the cavity 111, the addition process becomes more accurate and controllable.

[0045] Refer to Figure 4 As shown, in one embodiment, a thermometer 113 for measuring the temperature of the cavity 111 is provided in the cavity 111, and the thermometer 113 can specifically be a temperature sensor, etc. Further, a temperature control unit is provided on the outer wall of the storage container 110. When the external environmental temperature is too high or too low, it will naturally affect the temperature of the flux in the storage container 110. The temperature in the cavity 111 is measured by the thermometer 113, and the temperature in the cavity 111 is adjusted through the temperature control unit to solve the problem that the flux solidifies at low temperature or deteriorates at high temperature, which affects subsequent use.

[0046] Refer to Figure 4As shown, in one embodiment, the temperature control unit includes a heating element 114 surrounding the outer wall of the storage container 110. The heating element 114 may specifically be an annular heating sheet, which surrounds the outer wall of the storage container 110, making the heating more uniform. Through the cooperation of the heating element 114 and the thermometer 113, the problem that the flux is prone to solidify due to temperature influence and is inconvenient to use is solved.

[0047] Refer to Figure 4 As shown, further, the temperature control unit includes a cooling element 115 attached to the outer wall of the storage container 110. When the external temperature is too high and the temperature of the flux in the cavity 111 rises, in order to prevent the flux from deteriorating and affecting the subsequent welding stability, it is cooled to an appropriate storage temperature through the cooling element 115, improving the reliability of the flux. The cooling element 115 may specifically be a thermoelectric cooler, etc.

[0048] Refer to Figure 4 As shown, in one embodiment, a stirring blade 116 is provided in the cavity 111. The flux in the cavity 111 is moderately stirred by the stirring blade 116, making the crystalline substances and the solution of the flux mix evenly, improving the performance of the flux and avoiding the solidification of the flux, etc.

[0049] In some embodiments, a handrail (not shown in the figure) is provided on the side of the storage container, and four walking wheels (not shown in the figure) are provided on the bottom surface of the storage container. The provision of the handrail and the walking wheels is conducive to the operator moving the flux storage device to the required position, such as a position closer to the container to be refilled, so as to be able to shorten the length of the connecting pipe between the storage container and the container to be refilled, further improving the convenience of refilling and reducing the difficulty of refilling.

[0050] Specifically, the wheels provided near the handrail are universal wheels, and the wheels provided away from the handrail are directional wheels. The universal wheels and the directional wheels are installed at different parts of the storage container, enabling the storage device to move and turn more flexibly and quickly.

[0051] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0052] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
