Description

Technical Field

[0001] This application relates to the field of flux coating technology, and more specifically, to a flux coating apparatus. Background Technology

[0002] Flux is a chemical agent used to assist in soldering. It helps remove oxide layers from metal surfaces, improves the wettability and flowability of the solder, thereby enhancing the quality and reliability of the solder joint. In the electronics industry, tin plating is often a crucial production step in the manufacturing of ribbon cables, and flux application is an indispensable step. During the tin plating process, applying flux helps improve the adhesion and uniformity of the tin layer, reduces the formation of solder balls and dross, and improves the reliability of the solder joint.

[0003] In existing technology, workers use a brush to dip into a container of flux solution and then apply the flux to the tin-plated parts of the ribbon cable. However, the amount of flux applied manually is uncontrollable; applying too much flux is wasteful and can cause the product to become dirty, affecting quality, while applying too little flux affects the soldering quality. In addition, manual flux application is inefficient and affects production efficiency. Summary of the Invention

[0038] like Figure 1-5As shown, this application provides a flux coating apparatus, including a solder pot 1, a furnace box 2, a support assembly 3, a flux coating assembly 4, a conveying assembly 5, and a controller 6. The solder pot 1 is used to heat molten solder for tin plating of the ribbon cable. The solder pot 1 is located inside the furnace box 2. An opening 21 is provided on one side of the furnace box 2, allowing the solder pot 1 to be placed into or removed from the furnace box 2. Placing the solder pot 1 inside the furnace box 2 reduces the space occupied by the equipment. A tin plating port 22 is provided on the top of the furnace box 2, through which molten solder from the solder pot 1 can be dipped. Support assembly 3 is located on the top of furnace box 2, and flux coating assembly 4 is located on support assembly 3. Flux coating assembly 4 includes a recovery tank 41, a lifting cylinder 42, a first fixed seat 43, and a second fixed seat 44. Recovery tank 41 is located on the top of furnace box 2, lifting cylinder 42 is located on support assembly 3, first fixed seat 43 is fixed to the telescopic rod of lifting cylinder 42, and second fixed seat 44 is located on recovery tank 41. First fixed seat 43 is located directly above second fixed seat 44. Lifting cylinder 42 drives first fixed seat 43 to move closer to or away from second fixed seat 44. The system has a first coating sponge 433 on top and a second coating sponge 442 on a second fixed base 44. A conveying assembly 5 is used to quantitatively deliver flux to the first coating sponge 433. A controller 6 is located on the support assembly 3 and controls the operation of the conveying assembly 5. In use, the cable is placed on the second coating sponge 442, and then the lifting cylinder 42 drives the first fixed base 43 to move downwards, thereby moving the first coating sponge 433 downwards. Simultaneously, the controller 6 controls the conveying assembly 5 to quantitatively deliver flux to the first coating sponge 433. The flux enters the first coating sponge 433, and when the first coating... When the sponge 433 is pressed against the ribbon cable, the flux of the first coating sponge 433 is applied to the ribbon cable. Then, the lifting cylinder 42 drives the first fixed seat 43 to move upward, thereby moving the first coating sponge 433 upward, taking out the ribbon cable and flipping it over to place it on the second coating sponge. The lifting cylinder 42 then drives the first fixed seat 43 to move downward, moving the first coating sponge 433 downward, completing the coating of the other side of the ribbon cable. Compared with the prior art, it can control the amount of flux applied to the ribbon cable, avoid the impact of too much or too little flux on the quality of the ribbon cable, improve flux coating efficiency, and improve the production efficiency of the ribbon cable.

[0039] like Figure 1 , Figure 2 and Figure 5As shown, the support assembly 3 includes a first support plate 31, a second support plate 32, and a mounting plate 33. The first support plate 31 and the second support plate 32 are both fixed to the top of the furnace box 2. The mounting plate 33 is installed on the first support plate 31 and the second support plate 32. Specifically, the mounting plate 33 is provided with a set of parallel mounting holes. The mounting holes are elliptical. By passing screws through the mounting holes and tightening them, the mounting plate 33 is installed on the first support plate 31 and the second support plate 32. The height of the mounting plate 33 can be adjusted according to actual needs.

[0040] like Figure 1 , Figure 2 and Figure 5 As shown, a smoke exhaust hole 311 is provided on the first support plate 31, and a smoke exhaust pipe 7 is fixed at the smoke exhaust hole 311. The smoke exhaust pipe 7 is connected to the exhaust fan. The exhaust fan draws away the toxic fumes generated during tin plating and removes them from the workshop through the smoke exhaust pipe 7, thus protecting the health of the workers.

[0041] like Figure 1 and Figure 5 As shown, a filter screen 71 is installed at the smoke inlet of the smoke exhaust pipe 7. The filter screen 71 prevents large foreign objects from entering the smoke exhaust pipe 7 and causing blockage or affecting the normal operation of the exhaust fan.

[0042] like Figure 2 As shown, the bottom of the first fixing seat 43 is provided with a lower groove 431, and the top of the first fixing seat 43 is provided with an upper groove 432. The first coating sponge 433 is disposed in the lower groove 431. Specifically, the first fixing seat 43 is provided with a plurality of fixing holes that penetrate the lower groove 431. The first coating sponge 433 is fixed in the groove by means of bolts passing through the fixing holes and the first coating sponge 433, and then by means of nuts, so as to facilitate disassembly and replacement.

The conveying pipe 51 is connected to the first fixed base 43 and extends into the first coated sponge 433. The metering control valve 52 is electrically connected to the controller 6.

[0045] like Figure 1 , Figure 2 and Figure 5As shown, a scraper 8 is provided at the tin plating port 22. After the ribbon cable is coated with flux, it is moved to the tin plating port 22 for tin plating. After tin plating, the scraper 8 is used to remove the excess tin liquid from the ribbon cable.

[0046] like Figure 2 As shown, scraper teeth 81 are symmetrically and evenly arranged on both sides of the scraper 8. The scraper teeth 81 on the scraper 8 can remove excess solder on the ribbon cable and make the solder on the ribbon cable evenly distributed.

[0047] The flux coating device also includes a dip plate (not shown in the figure), which is used to dip the molten solder onto the tin-plated part of the ribbon cable.

[0048] Working principle:

[0049] In use, connect the exhaust pipe 7 to the exhaust fan and start the exhaust fan. Then, turn on the solder pot 1 to heat the molten solder on the solder pot 1. Place the ribbon cable on the second coating sponge 442. Then, the lifting cylinder 42 drives the first fixed seat 43 to move down, thereby moving the first coating sponge 433 down. At the same time, the controller 6 controls the conveying component 5 to deliver flux to the first coating sponge 433 in a quantitative manner. The flux enters the first coating sponge 433. When the first coating sponge 433 is pressed against the ribbon cable... The flux from the first coating sponge 433 is applied to the ribbon cable. Then, the lifting cylinder 42 drives the first fixed seat 43 to move upward, which in turn moves the first coating sponge 433 upward. The ribbon cable is then removed and flipped onto the second coating sponge. The lifting cylinder 42 drives the first fixed seat 43 to move downward, which in turn moves the first coating sponge 433 downward, completing the coating on the other side of the ribbon cable. After the ribbon cable is coated with flux, it is moved to the tin plating port 22 for tin plating. After tin plating, the excess tin liquid on the ribbon cable is scraped off with the scraper 8.

[0050] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
