Description

Technical Field

[0001] This utility model relates to the field of new energy technology, specifically to a novel photovoltaic module dip welding equipment. Background Technology

[0002] With the continuous development of society and economy, photovoltaic equipment has emerged. Its key component is the string welding machine, and the ribbon processing technology of the string welding machine is an indispensable part of modern photovoltaic module production. In the existing ribbon processing technology, the flux is placed statically in the flux bath, which is prone to sedimentation and stratification. Furthermore, the sedimentation of the flux may cause changes in the chemical composition of the flux bath, which not only affects the flux's effect on the ribbon, but also requires additional cleaning steps for the sediment in the flux bath. At the same time, it is necessary to replace the flux, which increases production costs and reduces the production efficiency of the ribbon.

[0003] For example, patent document with patent application number 202420092923.3 and publication date of August 9, 2024 discloses an automatic flux filling mechanism for battery cells, including a support assembly and a flux tank assembly. The flux tank assembly is fixedly mounted on the support assembly. The flux tank assembly includes a solder strip limiting and immersion assembly, a liquid level sensing assembly, a temperature sensing assembly, and a heating assembly. The solder strip limiting and immersion assembly includes at least one solder strip limiting and pressing mechanism and a solder strip immersion wheel mechanism. At least one of the solder strip limiting and pressing mechanisms and the solder strip immersion wheel mechanism are respectively mounted on the flux tank assembly. This discloses a string welding device for battery cells, which effectively realizes automatic flux filling through the cooperation of the solder strip limiting and immersion assembly, the liquid level sensing assembly, the temperature sensing assembly, and the heating assembly.

[0004] The above literature describes a flux tank with a filling port and a drain port. When the liquid level sensing component detects that the flux level in the flux tank body has dropped to a certain preset value, the solenoid valve on the filling port opens to add flux to the flux tank body. Only under these circumstances does the flux in the flux tank agitate. When the string welding machine is running in a static immersion tank, the immersion liquid is prone to component separation, resulting in uneven chemical composition inside the liquid, which affects the heat transfer efficiency. Summary of the Invention

[0005] This invention provides a novel photovoltaic module dip welding equipment, which has a simple structure, is safe and reliable, and has a long service life.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a novel photovoltaic module dip-soldering equipment, comprising a support and a material tank, wherein the support is provided with an immersion tank containing flux, the material tank is used to store flux, the immersion tank is provided with a circulation component, the circulation component includes a circulation outlet and a circulation inlet, the circulation outlet is located on one side of the bottom of the immersion tank, the circulation inlet is located on the outer side of the immersion tank wall, the circulation outlet is connected to the material tank, and a circulation device is provided on one side of the support, the circulation device including a circulation pump, the circulation pump being provided with a circulation pump inlet and a circulation pump outlet, the circulation pump inlet being connected to the material tank, and the circulation pump outlet being connected to the circulation inlet.

[0007] In the above setup, the immersion tank contains flux, and the solder strip comes into contact with the flux after passing through the immersion tank, thereby completing the processing of the solder strip. As the solder strip is processed, the flux in the immersion tank will decrease. Therefore, it is necessary to connect the immersion tank to the material tank so that the flux in the immersion tank can be replenished or replaced in a timely manner.

[0008] A circulation outlet is located at the bottom of the soaking tank, and a circulation inlet is located on the outer side of the tank wall. A circulation pump is installed on one side of the support, with an inlet and an outlet. The outlet is connected to the material tank, the inlet to the material tank, and the outlet to the inlet. To prevent flux sedimentation during the processing of the solder strip, a circulation assembly and device are installed. During circulation, the flux first flows back to the material tank from the outlet, and then the circulation pump operates again, ensuring that the flux flows smoothly within the material tank as it enters the pump inlet. To prevent flux from settling at the bottom of the immersion tank and to ensure its uniformity, the flux's chemical composition changes during storage, thus preventing a shortened lifespan. The flux flows back to the immersion tank from the immersion tank and then to the circulation pump. The circulation pump outlet connects to the circulation inlet, allowing the flux to flow back into the immersion tank. This process of flux flowing out and then back into the immersion tank prevents it from remaining stagnant at the bottom for extended periods, avoiding sedimentation and ensuring the flux is in optimal working condition, thereby improving the processing efficiency and quality of the solder strip.

[0009] Furthermore, the bottom of the soaking tank is also provided with a water outlet, a liquid replenishment outlet, and a first liquid discharge outlet.

[0010] The above setup includes an outlet at the bottom of the soaking tank. When cleaning the tank, flux is drained through the outlet, allowing for thorough cleaning. A replenishment port is located on one side of the bottom of the tank, connected to a material tank. After cleaning, flux is added back into the tank through this port. A first discharge port is located on the other side of the bottom of the tank, also connected to a material tank. When there is excessive flux in the tank, it is drained back into the tank through this port, maintaining the appropriate flux concentration and ensuring effective flux application during soldering.

[0011] Furthermore, a second discharge port is provided on one side of the circulation inlet.

[0012] In addition to the above configuration, a second discharge port is also provided on the side of the circulation inlet. The second discharge port is connected to the material tank. When adjusting the flux concentration, the flux can be discharged into the material tank through the second discharge port.

[0013] Furthermore, the interior of the soaking tank is recessed along the direction of the water outlet.

[0014] The above design, with the immersion tank recessed along the water outlet direction, allows for faster removal of flux when the immersion tank needs cleaning.

[0015] Furthermore, a front guide wheel is installed at one end of the soaking tank, a middle guide wheel is provided in the middle of the soaking tank along its length, and a rear guide wheel is provided at the end of the soaking tank away from the front guide wheel.

[0016] With the above setup, the welding strip moves in the immersion tank under the traction of the front guide wheel, middle guide wheel and rear guide wheel, so that the welding strip comes into contact with the flux, and then the welding strip moves to the outside of the immersion tank.

[0017] Furthermore, pressure rods are provided at both ends above the front guide wheel and at both ends above the rear guide wheel.

[0018] The above settings, through the setting of the pressure rod, limit the height of the welding strip entering and exiting the soaking tank, so as to complete the soaking smoothly.

[0019] Furthermore, a detection instrument is installed between the rear guide wheel and the middle guide wheel.

[0020] The above setup includes a detector installed between the rear guide wheel and the middle guide wheel of the immersion tank. This detector can check the depth of flux in the immersion tank and add or remove flux as needed to meet the required immersion depth for the solder strip.

[0021] Furthermore, a handle is installed on one side of the soaking tank along its length.

[0022] The above features include a handle installed on one side of the soaking tank, making installation and subsequent maintenance of the soaking tank convenient. Attached Figure Description

Detailed Implementation

[0027] Example 1.

[0028] The flux tank (not shown in the figure), as described in CN 215624286 U, is used to store flux. The flux tank is equipped with connection points to the circulation outlet of the immersion tank, the replenishment port, the first discharge port, the second discharge port, and the circulation pump inlet, so that the flux can reach the flux tank through the circulation outlet, the first discharge port, and the second discharge port, and so that the flux can reach the replenishment port and the circulation pump inlet through the flux tank.

[0029] like Figure 1-3 As shown, a novel photovoltaic module dip-soldering equipment includes a support frame 2 and a material tank (not shown in the figure). The support frame 2 is equipped with an immersion tank 1 containing flux. The material tank (not shown in the figure) stores the flux. The immersion tank 1 is equipped with a circulation component, which includes a circulation outlet 12 and a circulation inlet 11. The circulation outlet 12 is located on one side of the bottom of the immersion tank 1, and the circulation inlet 11 is located on the outer side of the wall of the immersion tank 1. The circulation outlet 12 is connected to the material tank (not shown in the figure). A circulation device is provided on one side of the support frame 2. The circulation device includes... The system includes a circulating pump 21, which has a circulating pump inlet 212 and a circulating pump outlet 211. The circulating pump inlet 212 is connected to a material tank (not shown in the figure), and the circulating pump outlet 211 is connected to a circulating inlet 11. The immersion tank 1 contains flux, and the solder strip comes into contact with the flux after passing through the immersion tank 1, thereby completing the processing of the solder strip. As the solder strip is processed, the flux in the immersion tank 1 will decrease. Therefore, it is necessary to connect the immersion tank 1 to the material tank (not shown in the figure) so that the flux in the immersion tank 1 can be replenished or replaced in a timely manner.

[0030] A circulation outlet 12 is provided at the bottom of the soaking tank 1, and a circulation inlet 11 is provided on the outer side of the wall of the soaking tank 1. A circulation pump 21 is provided on one side of the support 2. The circulation pump 21 is provided with a circulation pump inlet 212 and a circulation pump outlet 211. The circulation outlet 12 is connected to the material tank (not shown in the figure), the circulation pump inlet 212 is connected to the material tank (not shown in the figure), and the circulation pump outlet 211 is connected to the circulation inlet 11. When the solder strip is processed in the soaking tank 1, in order to prevent the flux from settling in the soaking tank 1, a circulation component and circulation device are provided. When the flux is circulating, it first flows back to the material tank (not shown in the figure) through the circulation outlet 12, and then the circulation pump works to make the flux flow from the material tank (not shown in the figure) into the circulation pump inlet 212, so that... The flux flows in the container (not shown in the figure), which prevents the flux from settling at the bottom of the container (not shown in the figure). This helps to ensure the uniformity of the flux and prevents the chemical composition of the flux from changing during storage, which could shorten its service life. The flux in the immersion tank 1 flows back to the container (not shown in the figure) and then reaches the circulation pump 21. It is connected to the circulation inlet 11 through the circulation pump outlet 211, allowing the flux to flow back to the immersion tank 1. Therefore, the flux flows out of the immersion tank 1 and then back in. During this process, the flux flows in the immersion tank 1, so the flux will not stand at the bottom of the immersion tank 1 for a long time, avoiding the formation of sediment. This keeps the flux in its optimal working state, thereby improving the processing efficiency and effect of the solder strip.

[0031] like Figure 1-2 As shown, the bottom of the soaking tank 1 is also equipped with a water outlet 13, a replenishment port 14, and a first discharge port 15. The water outlet 13 is provided at the bottom of the soaking tank 1. When it is necessary to clean the soaking tank 1, the flux is discharged through the water outlet 13, thereby cleaning the soaking tank 1. The replenishment port 14 is provided on one side of the bottom of the soaking tank 1. The replenishment port 14 is connected to the material tank (not shown in the figure). When it is necessary to inject flux into the soaking tank 1 after cleaning, the flux is injected into the soaking tank 1 through the replenishment port 14. The first discharge port 15 is provided on the other side of the bottom of the soaking tank 1. The first discharge port 15 is connected to the material tank (not shown in the figure). When there is too much flux in the soaking tank 1, the flux can be flowed back to the material tank (not shown in the figure) through the first discharge port 15, so that the flux concentration in the soaking tank 1 is maintained at the proper level, ensuring that the flux can play an effective role when the solder strip is processed in the soaking tank 1.

[0032] A second discharge port 16 is provided on one side of the circulation inlet 11. The second discharge port 16 is connected to the material tank (not shown in the figure). When adjusting the flux concentration, the flux can flow out to the material tank (not shown in the figure) through the second discharge port 16.

[0033] like Figure 2-3 As shown, the interior of the soaking tank 1 is recessed along the direction of the water outlet 13. This recess in the interior of the soaking tank 1 along the water outlet direction allows the flux to be removed more quickly when the soaking tank 1 needs to be cleaned.

[0034] A front guide wheel 3 is installed at one end of the soaking tank 1, a middle guide wheel 4 is provided in the middle of the length direction of the soaking tank 1, and a rear guide wheel 5 is provided at the end of the soaking tank 1 away from the front guide wheel 3. The welding strip moves in the soaking tank 1 under the traction of the front guide wheel 3, the middle guide wheel 4 and the rear guide wheel 5 in the soaking tank 1, so that the welding strip comes into contact with the flux, and then the welding strip moves to the outside of the soaking tank 1.

[0035] Pressure rods 31 are provided at both ends above the front guide wheel 3 and the rear guide wheel 5. The pressure rods 31 are provided at both ends above the rear guide wheel 5. By setting the pressure rods 31, the height of the welding strip entering and exiting the soaking tank 1 is limited so that the soaking can be completed smoothly.

[0036] A detector 6 is installed between the rear guide wheel 5 and the middle guide wheel 4 in the immersion tank 1. The detector 6 can check the depth of flux in the immersion tank 1 and add or remove flux in time to meet the immersion depth of the solder strip.

[0037] A handle 7 is installed on one side of the soaking tank 1 along its length, which facilitates the installation and subsequent maintenance of the soaking tank 1.

[0038] The working principle of this utility model is as follows: A circulation outlet 12 is provided at the bottom of the soaking tank 1, and a circulation inlet 11 is provided on the outer side of the wall of the soaking tank 1. A circulation pump 21 is provided on one side of the support 2. The circulation pump 21 is provided with a circulation pump inlet 212 and a circulation pump outlet 211. The circulation outlet 12 is connected to the material tank (not shown in the figure), the circulation pump inlet 212 is connected to the material tank (not shown in the figure), and the circulation pump outlet 211 is connected to the circulation inlet 11. When the welding strip is processed in the soaking tank 1, the flux can flow from the circulation outlet 12 to the material tank (not shown in the figure). Then, the circulation pump 21 works to make the flux flow from the material tank (not shown in the figure) through the circulation pump inlet 212, and then through the circulation pump outlet 211 to the circulation inlet 11, so that the flux can flow in the material tank (not shown in the figure) and the soaking tank 1 to prevent the flux from settling.

[0039] A water outlet 13 is provided at the bottom of the soaking tank 1. When it is necessary to clean the soaking tank 1, the flux is discharged through the water outlet 13 to clean the soaking tank 1. A liquid replenishment port 14 is provided on one side of the bottom of the soaking tank 1. The liquid replenishment port 14 is connected to the material tank (not shown in the figure). When it is necessary to inject flux into the soaking tank 1 after cleaning, the flux is injected into the soaking tank 1 through the liquid replenishment port 14. A first liquid discharge port 15 is provided on the other side of the bottom of the soaking tank 1. The first liquid discharge port 15 is connected to the material tank (not shown in the figure). Next, when there is too much flux inside the immersion tank 1, the flux can be flowed back to the material tank (not shown in the figure) through the first discharge port 15, so that the flux concentration in the immersion tank 1 is maintained at the proper level, ensuring that the flux can play an effective role when the solder strip is processed in the immersion tank 1. A second discharge port 16 is also provided on one side of the circulation inlet 11. The second discharge port 16 is connected to the material tank (not shown in the figure). When adjusting the flux concentration, the flux can be flowed out to the material tank (not shown in the figure) through the second discharge port 16.
