Description

Technical Field

[0001] The utility model relates to the technical field of string welding equipment, and in particular to a flux smearing device. Background Art

[0002] When the flux is loaded into the conventional string soldering machine coating device, the flux water flow is strong, which will cause splashing and water splashing in the flux storage box. For example, the Chinese utility model patent, publication number: CN208772769U, is titled: A flux coating method and string soldering machine. When the flux liquid is loaded into the flux storage box, the liquid in the flux discharge port is directly sprayed into the storage box; the flux liquid will splash and contaminate the top cover or the equipment. The flux itself is highly corrosive, so it will cause equipment pollution and damage. Summary of the Invention

[0003] In order to solve the above problem that the loading flux has a great impact on the liquid storage box, which may cause the flux to splash and spill, causing corrosion to the equipment and the top cover, the utility model proposes a flux coating device; the specific solution is as follows:

[0004] The flux coating device includes a flux storage box and a flux adding mechanism; the flux adding mechanism is installed inside the flux storage box; the flux adding mechanism includes at least three shielding columns and an adding port; the shielding columns include a first shielding column, a second shielding column and a third shielding column; the first shielding column is opposite to the second shielding column, and the first shielding column and the second shielding column are respectively at the two ends of the third shielding column; the adding port is placed in the middle direction of the shielding column, and the three shielding columns and the liquid storage box form a filling groove; the filling groove is formed by adopting the shielding columns, so that the flux can only be loaded in the shielded filling groove space, avoiding the flux liquid from splashing and contaminating the top cover or the equipment. Even if splashing occurs, it is limited to the filling groove, reducing the possibility of external splashing, maintaining the safety of the equipment and ensuring the long-term operation of the equipment.

[0005] Preferably, the liquid storage box also includes an immersion roller, which is installed inside the liquid storage box, and there is a gap between the lower end of the immersion roller and the bottom of the liquid storage box; the smear is pressed down by the immersion roller into the flux liquid, such as "solder strip" and "long line", so that the smeared object is fully immersed and smeared.

[0006] Specifically, stirring devices are provided at both ends of the immersion drum for stirring the flux; the stirring devices of the immersion drum can make the flux dissolve more thoroughly and can also prevent the flux from being uneven or condensing into crystals.

[0007] In particular, a slope is formed at the bottom of the liquid storage box in the direction of the solder strip entering and exiting; the height of the slope is higher than the height of the filling groove; by designing the height of the slope to be higher than the height of the filling groove, on one hand, the slope can be used to further enclose the filling groove on one side of the filling groove, making it more difficult for the flux to splash; on the other hand, the flow rate of the flux when it is loaded through the slope will be slowed down, thereby avoiding splashing again.

[0008] Preferably, the liquid storage box also includes a liquid level sensor, the liquid level sensor includes a liquid level sensing switch, and the liquid level sensing switch is electrically connected to the addition port; by installing a liquid level sensor to sense the rise and fall of the flux liquid level, it is beneficial to control the flux filling while saving equipment costs.

[0009] Specifically, the liquid storage box also includes guide wheels, which include a first guide wheel and a second guide wheel. The guide wheels are parallel to the immersion roller and are respectively installed at the inlet and outlet ends of the liquid storage box; the guide wheels are used to import and export the solder strip, ensuring the correct coating direction of the solder strip.

[0010] Preferably, the soldering flux smearing device further comprises a box cover which is rotatably opened and closed and is arranged on the liquid storage box. Through the box cover, even if soldering flux splashes during use, the soldering flux can be confined in the liquid storage box to avoid contaminating the machine table or other equipment.

[0011] Specifically, the flux storage box cover includes a bent chimney, which is installed on the box cover. The design of the bent chimney frees up equipment space in the direction of opening the box cover, eliminating the need to reserve more space for the bent chimney to open, thereby saving equipment costs.

[0012] Preferably, a heating device is provided on the outer bottom of the flux storage box, and the heating device is installed at the bottom of the storage box; the heating device is used to heat the flux, thereby increasing the flux concentration, improving the welding quality, and ensuring the welding stability.

[0013] Specifically, the liquid storage box also includes a shock-absorbing pad, which is installed on the top of one side of the liquid storage box opening, and the top of the shock-absorbing pad is higher than the top height of the liquid storage box; by arranging the shock-absorbing pad at the opening of the liquid storage box, the box lid can be shock-absorbing and cushioned when closing the box lid, thereby avoiding the impact noise generated when the box lid is closed.

DETAILED DESCRIPTION

[0020] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0021] The utility model proposes a flux coating device, including a flux storage box and a flux adding mechanism; the flux adding mechanism is installed inside the flux storage box; the flux adding mechanism includes at least three shielding columns and an adding port 60; the shielding columns are divided into a first shielding column 61, a second shielding column 62 and a third shielding column 63; the first shielding column 61 is opposite to the second shielding column 62, and the first shielding column 61 and the second shielding column 62 are respectively at the two ends of the third shielding column 63; the adding port 60 is placed in the middle of the shielding columns, and the three shielding columns and the liquid storage box form a filling tank S, wherein the adding port 60 includes a liquid inlet pipe 58 and a liquid inlet 59; the flux liquid is sequentially loaded into the filling tank S through the liquid inlet 59 and the liquid inlet pipe 58 of the adding port 60. Because the flux liquid has strong corrosiveness, it is avoided by adopting the shielding columns. The splashing of flux liquid thereby contaminates the top cover or the equipment, thereby avoiding contamination of the equipment; the liquid storage box includes an immersion roller 83, a guide wheel and a liquid level sensor; the immersion roller 83 is installed inside the liquid storage box, and the guide wheel includes a first guide wheel 82 and a second guide wheel 86, wherein the guide wheel is parallel to the immersion roller 83 and is respectively installed at the inlet and outlet ends of the liquid storage box; the liquid level sensor is installed on the outside of the open end of the liquid storage box; in addition, a slope 13 is formed at the bottom of the liquid storage box in the direction of the welding strip in and out; the horizontal height of the slope 13 is higher than the filling slot S; by designing the horizontal height of the slope 13 to be higher than the filling slot S, on the one hand, the slope 13 can be used to further enclose the filling slot S on one side of the filling slot S, making it more difficult for the flux to splash, and on the other hand, the flow rate of the flux will be slowed down when flowing through the slope 13 when loading, thereby avoiding splashing again.

[0022] In this embodiment, multiple soldering strips can be coated with flux at the same time. The soldering strips are introduced into the liquid storage box through the guide wheel to complete the coating process and then guided to the next workstation, thereby ensuring the normal direction of the soldering strips. In order to allow the soldering strips to be fully coated, there is a gap between the lower end of the immersion roller 83 and the bottom of the flux. When the soldering strips are coated with flux, they enter through the first guide wheel 82 at the entrance and pass through the lower end of the immersion roller 83. The immersion roller 83 presses the soldering strips into the flux liquid for full immersion. The soldering strips pass through the lower end of the immersion roller 83 and are then guided out of the liquid storage box by the second guide wheel 86.

[0023] Preferably, stirring devices are provided at both ends of the immersion drum 83, and the stirring devices include a drum and a stirring tank. When the drum rotates, the stirring tank is driven to stir the flux. The stirring device of the immersion drum 83 can make the flux dissolve more thoroughly and prevent the flux from being uneven or condensed into crystals.

[0024] In this embodiment, the liquid level sensor includes a liquid level sensing switch 85 and a connecting tube 90. The liquid level sensing switch 85 is electrically connected to the adding port 60. If the liquid level sensing switch 85 senses that the flux is higher than the middle position of the connecting tube 90, it indicates that the flux in the flux storage box has reached a certain height. In this way, the adding port 60 can be controlled to stop continuing to inject flux into the flux storage box to avoid flux overflow.

[0025] Similarly, if the flux sensing switch 85 senses that the flux liquid is lower than the middle position of the connecting tube 90, it indicates that the flux liquid in the flux storage box is reduced, and the flux liquid needs to be added through the addition port 60 to avoid uneven coating of the solder strip; by installing a liquid level sensor to sense the rise and fall of the flux liquid level, it is beneficial to timely add the flux liquid while saving equipment costs.

[0026] Among them, the flux coating device also includes a box cover 40, which is rotatably opened and closed and is set on the liquid storage box; the box cover 40 includes a bending chimney 20, which is installed on the box cover 40; the design of the bending chimney 20 frees up the equipment space in the opening direction of the box cover 40, and there is no need to reserve more space for the bending chimney 20 to open, thereby saving equipment costs.

[0027] A heating device 70 is also provided at the bottom of the flux storage box, and the heating device 70 is installed at the bottom of the liquid storage box; it is used to heat the flux, thereby increasing the flux concentration by heating the flux, increasing the welding quality of the soldering strip, and ensuring welding stability; and because the flux will volatilize and produce a large amount of waste gas when heated, a large amount of waste gas is discharged from the box through the bent chimney 20, which not only ensures the concentration of the flux liquid, but also avoids polluting the air and purifies the environment.

[0028] The liquid storage box further includes a shock-absorbing pad 84, which is installed at the top of one side of the liquid storage box opening, and the top of the shock-absorbing pad 84 is higher than the liquid storage box; by arranging the shock-absorbing pad 84 at the opening of the liquid storage box, the box cover 40 can be shock-absorbing and cushioned when closing the box cover 40, thereby avoiding the impact noise generated when the box cover 40 is closed.

[0029] In summary, in order to avoid the strong water flow when the flux liquid is added during the application of the soldering ribbon, which will cause splashing and water splashing in the flux storage box; the utility model adopts a flux adding mechanism to form a filling slot S through a shielding column and the bottom of the storage box,

[0030] By using shielding columns to form a filling slot S, the flux can only be loaded in the space enclosed by the shielding filling slot S, preventing the flux liquid from splashing and contaminating the top cover or equipment. Even if splashing occurs, it is limited to the filling slot S, reducing the possibility of external splashing, maintaining the safety of the equipment and ensuring the long-term operation of the equipment.
