Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a flux supply trough structure. Background Art

[0002] Flux is a commonly used auxiliary material in the welding process. It is used to remove oxides on the surface of solder joints, improve the wettability and fluidity of solder, and thus ensure welding quality and reliability. During the welding process, a flux supply tank is usually used to store and supply flux. The filtered flux is heated in the supply tank and then discharged through the liquid outlet to assist the welding operation. When the injection volume of the liquid inlet is greater than the discharge volume of the liquid outlet, the liquid outlet cannot discharge the flux in time, and the flux will accumulate in the supply tank. Excessive accumulation of flux until it overflows is not conducive to safe production, and the flux needs to be discharged in time.

[0003] In view of the above problems, a flux supply trough structure is now developed. Utility Model Content

[0004] In order to overcome the disadvantage that when the injection volume of the liquid inlet is greater than the discharge volume of the liquid outlet, the liquid outlet cannot discharge the flux in time, the flux will accumulate in the supply tank, and the excessive accumulation of flux until it overflows outward is not conducive to safe production, and the flux needs to be discharged in time, the utility model provides a flux supply tank structure.

[0005] The technical implementation scheme of the present utility model is: a flux supply trough structure, including a supply trough, a liquid inlet is provided on the left side of the supply trough, a liquid outlet is provided on the right side of the supply trough, overflow outlets are provided at the front and rear parts of the supply trough, reflux plates are provided at the front and rear interiors of the supply trough, the reflux plates are located between the adjacent overflow outlets and the supply trough, a heating plate is installed at the lower part of the supply trough, a top plate is clamped at the upper part of the supply trough, filter elements are slidably connected to the left and right sides of the supply trough, a reflux pipe is connected between the front and rear sides of the lower right part of the supply trough, and the reflux pipe facilitates the discharge of flux on the reflux plate.

[0006] More preferably, the reflow plates are all inclined structures to facilitate the overflowing soldering flux to flow to the right.

[0007] More preferably, the lower sides of the front and rear parts of the top plate are both inclined structures that fit the return plate.

[0008] More preferably, the filter elements are all detachable connection structures.

[0009] More preferably, a limit block is provided on the upper portion of each filter element.

[0010] More preferably, a hollow rubber block is further included, and the filter element is provided with the hollow rubber block.

[0011] By adopting the above technical solution, compared with the prior art, the utility model has the following advantages:

[0012] The utility model is provided with an overflow port and a return flow plate. When the depth of the flux accumulation is higher than the height of the overflow port, the flux flows from the overflow port to both sides onto the return flow plate. The right-inclined inclined surface structure of the return flow plate can accelerate the flow speed of the flux, making it easier for the flux to quickly flow into the return pipe, thereby discharging the overflowed flux in time. This discharge method can be used as a backup path to ensure that the flux can be discharged smoothly to the outside, avoiding the liquid discharge limitations caused by a single channel.

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] A flux supply tank structure, such as Figure 1-Figure 4As shown, it includes a supply trough 1, a liquid inlet 2 is provided on the left side of the supply trough 1, a liquid outlet 3 is provided on the right side of the supply trough 1, an overflow port 4 is provided at the front and rear parts of the supply trough 1, a return plate 5 is provided at the front and rear interiors of the supply trough 1, the return plates 5 are located between adjacent overflow ports 4 and the supply trough 1, and the return plates 5 are all inclined structures that facilitate the overflow of the flux to flow to the right, a heating plate 6 is installed at the lower part of the supply trough 1, a top plate 7 is clamped at the upper part of the supply trough 1, and the lower sides of the front and rear parts of the top plate 7 are both inclined structures that fit the return plate 5, and the left and right sides of the supply trough 1 are both slidably connected with filter elements 8, and the filter elements 8 are detachable connection structures. The upper part of the filter element 8 is provided with a limit block, and the filter element 8 is provided with a hollow rubber block 9. A return pipe 10 is connected between the front and rear sides of the lower right part of the supply trough 1, and the return pipe 10 facilitates the discharge of the flux on the return plate 5.

[0020] It should be noted that flux is a commonly used auxiliary material in the welding process, which is used to remove oxides on the surface of the solder joint, improve the wettability and fluidity of the solder, and thus ensure the quality and reliability of welding. During the welding process, a flux supply tank 1 is usually used to store and supply flux, and the flux is transported to the supply tank 1 through the liquid inlet 2. The filter element 8 can filter out impurities in the flux. The heating plate 6 heats the flux in the supply tank 1 to ensure that the flux temperature is uniform. The flux is discharged from the liquid outlet 3 to assist the welding operation. When the injection amount of the liquid inlet 2 is greater than the discharge amount of the liquid outlet 3, the liquid outlet 3 cannot discharge the flux in time, and the flux will accumulate in the supply tank 1. Excessive accumulation of flux until it overflows is not conducive to safe production, and the flux needs to be discharged in time. When the depth of flux accumulation is higher than the height of the overflow port 4, the flux will flow from the overflow port 4 to both sides onto the return plate 5. The right-inclined inclined surface structure of the return plate 5 can speed up the flow of the flux, making it easier for the flux to quickly flow into the return pipe 10, thereby discharging the overflowed flux in time. This discharge method can be used as a backup path to ensure that the flux can be discharged smoothly to the outside, avoiding the liquid discharge limitations caused by a single channel. Since the filter element 8 is a consumable item and needs to be replaced regularly, the sliding connection method makes it more convenient to replace the filter element 8. The hollow rubber block 9 forms a closed space between the filter element 8 and the supply tank 1 to prevent flux leakage. The card-connected connection method of the top plate 7 makes it more convenient to disassemble and assemble the top plate 7, and is also conducive to quickly cleaning the inside of the supply tank 1.

[0021] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
