Description

Technical Field

[0001] This application relates to the field of flux production, and in particular to a flux mixing furnace. Background Technology

[0002] Flux has a wide range of applications in the electronics industry. Flux is a mixture of rosin and other fluxes that helps remove oxides from the soldering surface, improves soldering quality, and provides insulation, anti-aging, and corrosion resistance during the soldering process.

[0003] Rosin is solid at room temperature. When using rosin to make flux, it is often necessary to melt the rosin in a boiler at high temperature. At the same time, auxiliary materials such as solvents and antioxidants need to be added to the molten rosin. All raw materials are thoroughly mixed evenly by stirring or other methods to obtain the final flux product.

[0004] After rosin is melted at high temperature and auxiliary materials are added, it needs to be stirred with a stirrer. For example, a rosin melting furnace disclosed in Chinese utility model patent CN210862205U has a stirrer on the furnace. The stirrer needs to be lifted vertically to be pulled out of the furnace and then lifted above the furnace before being inserted and placed. The removal and placement of the stirrer is quite troublesome and laborious. Utility Model Content

[0005] To increase the efficiency of the agitator, a flux mixing furnace is provided.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A flux mixing furnace includes a cabinet and a stirring mechanism. The stirring mechanism includes a tooling frame and a stirrer. A heater is provided inside the cabinet, and a heating cylinder is placed inside the heater. A connecting piece is installed on the surface of the cabinet. The connecting piece is connected to the tooling frame by a hinged connection. The tooling frame is located above the heating cylinder, and the stirrer is fixed on the tooling frame.

[0008] By adopting the above technical solution, when using a rosin high-temperature furnace, the stirrer needs to be inserted into the heating cylinder to stir the rosin. However, it is very inconvenient for operators to insert and remove the stirrer. Compared with the prior art, this application has a tooling frame, on which the stirrer is fixed. The tooling frame is hinged to the connecting piece. The insertion depth of the stirrer can be changed by changing the angle between the tooling frame and the connecting piece, which improves the ease of use.

[0009] Optionally, the number of heating cylinders may be multiple, and the number of stirrers, heaters and heating cylinders may be equal.

[0010] By adopting the above technical solution, multiple heating cylinders are provided. When one heating cylinder heats and melts rosin, another heating cylinder can mix and stir the melted rosin with other auxiliary materials to obtain flux. Each heating cylinder is equipped with a stirrer to stir different heating cylinders, thereby improving the efficiency of the stirrer and helping to meet production needs and improve the economic benefits of rosin production.

[0011] Optionally, the heating cylinder is also provided with handles on both sides, and the cabinet surface is also provided with a limiting groove for inserting the handles.

[0012] By adopting the above technical solution, the heating cylinder is not fixedly connected to the table for easy transfer, but is equipped with a handle for easy lifting and placing. Since rosin is solid, the stirring mechanism may cause unmelted solid rosin to rotate when stirring. The rotation of unmelted solid rosin will cause the heating cylinder to shake and move. A limiting groove is provided here for the handle to be inserted, which reduces the movement of the heating cylinder when the stirring mechanism is stirring.

[0013] Optionally, a handle is also installed on the end of the tooling frame away from the connecting piece.

[0014] By adopting the above technical solution, a handle is provided to facilitate the lifting and lowering of the tooling frame.

[0015] Optionally, the tooling rack includes two tooling strips, with a handle located between and connecting the two tooling strips.

[0016] By adopting the above technical solution, the stability of the tooling frame is increased. When the mixer is stirring and fixing unmelted rosin, the mixer will shake, which will cause the tooling frame to shake. The handle connects the two tooling strips, reducing the shaking of the tooling frame when the mixer is stirring.

[0017] Optionally, the tooling strip includes a horizontal connecting part and a vertical connecting part, the horizontal connecting part and the vertical connecting part forming a certain angle, and the angle is less than 180 degrees.

[0018] By adopting the above technical solution, since the horizontal and vertical connecting parts of the tooling strip are at a certain angle, when the tooling frame is lifted, the vertical connecting part of the tooling strip can be placed on the cabinet at a certain angle. Since the surface of the agitator will retain residual heat and liquid after a long period of agitation, placing the tooling strip on the surface of the cabinet and suspending the agitator can reduce contact with the operator. On the other hand, since the agitator is installed on the tooling frame, placing the vertical connecting part on the cabinet can make the center of gravity evenly fall on the cabinet, ensuring the stability of the connection between the connecting piece and the vertical connecting part after long-term use.

[0019] Optionally, the heating cylinder further includes a temperature measuring column, and an insertion tube for inserting the temperature measuring column is fixed on the inner wall of the opening of the heating cylinder.

[0020] By adopting the above technical solution, when the stirring mechanism stirs the unmelted rosin solid, it avoids the heating cylinder from moving and colliding with the temperature measuring column.

[0021] Optionally, a filter assembly may also be included, which is mounted on the inlet of the heating cylinder.

[0022] By adopting the above technical solution, the filter assembly is used to filter unmelted rosin. With the help of two heating cylinders, the filtration process can be carried out without holding the filter by hand, reducing extra operations and improving the quality and purity of the rosin.

[0023] In summary, this application has at least the following beneficial effects:

[0024] 1. In the high-temperature rosin melting furnace, the stirrer needs to be inserted into the heating cylinder to stir the rosin; after the rosin is melted, other auxiliary materials need to be added, and the stirrer is needed to stir it during the process. Therefore, the amount of stirrers used in actual production is large. In this application, the stirrer is fixed on the tooling frame, and the tooling frame is hinged to the connecting plate. The insertion depth of the stirrer can be changed by changing the angle between the tooling frame and the connecting plate, which improves the ease of use.

[0025] 2. Multiple heating cylinders are provided. When one heating cylinder heats and melts rosin, another heating cylinder can mix and stir the melted rosin with other auxiliary materials to obtain flux after uniform mixing. Each heating cylinder is equipped with a stirrer to stir different heating cylinders, thereby improving the efficiency of the mixer and helping to meet production needs and improve the economic benefits of rosin production.

Detailed Implementation

[0031] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0032] As attached Figure 1 As shown, a flux mixing furnace includes a cabinet 1, a stirring mechanism 2, and a filter assembly 3.

[0033] As attached Figure 2 As shown, a heater 11 is located inside the cabinet 1, and a heating cylinder 12 is installed inside the cabinet 1. Two cylindrical grooves 15 communicating with the heater 11 are also opened on the surface of the cabinet 1. Two heating cylinders 12 are placed inside the cylindrical grooves 15. The heating cylinder 12 is cylindrical in shape, and its bottom contacts the surface of the heater 11. The heating cylinder 12 also includes a temperature measuring column 121. An insertion tube 122 for inserting the temperature measuring column 121 is opened on the inner wall of the opening of the heating cylinder 12. A temperature measuring port 1221 is opened on the lower side of the insertion tube 122, and the lower end of the temperature measuring column 121 contacts the molten material in the heating cylinder 12 through the temperature measuring port 1221. When the stirring mechanism 2 stirs the unmelted rosin solid, it prevents the heating cylinder 12 from moving and colliding with the temperature measuring column 121.

[0034] As attached Figure 1 and attached Figure 3 As shown, multiple limiting grooves 13 are also opened on the surface of the cabinet 1. Two handles 123 are installed on the outer wall of the opening of the heating cylinder 12, and the handles 123 can be inserted into the limiting grooves 13; this facilitates the transfer of the heating cylinder 12 and can prevent the heating cylinder 12 from rotating and reduce vibration.

[0035] The filter assembly 3 includes a placement rack 31 and a filter screen 32. The placement rack 31 is installed around the opening of the filter screen 32. After the rosin in the heating cylinder 12 has completely melted, the melted rosin is poured into another heating cylinder 12. The filter screen 32 is placed at the opening of the other heating cylinder 12 to filter the unmelted rosin. The filter screen does not need to be held by hand, which reduces the extra operation.

[0036] A connecting piece 14 is also installed on the surface of the cabinet 1. The connecting piece 14 is L-shaped. One side of the connecting piece 14 is fixed to the surface of the cabinet 1 by a stud, and the other side has a first through hole 141. There are four connecting pieces 14, and the connecting pieces 14 are located on the side of the cylindrical groove 15. Here, two connecting pieces 14 are referred to as a group, and the number of groups of connecting pieces 14 is equal to the number of cylindrical grooves 15.

[0037] As attached Figure 1 and attached Figure 4 As shown, the stirring mechanism 2 includes a stirrer 21, a tooling frame 22, a rotating shaft 23, and a stirring impeller 24.

[0038] The tooling frame 22 is located above the heating cylinder 12. The tooling frame 22 includes tooling strips 221 and pins 223. There are two tooling strips 221, each including a horizontal connecting part 2211 and a vertical connecting part 2212. The connection between the horizontal connecting part 2211 and the vertical connecting part 2212 is at a certain angle, which is less than 180 degrees, preferably 90 degrees. A second through hole 2212-1 is opened at the end of the vertical connecting part 2212. The first through hole 141 and the second through hole 2212-1 are coaxially aligned, and the pin 223 is hinged to the first through hole 141 and the second through hole 2212-1.

[0039] When the tooling frame 22 is lifted, since the horizontal connecting part 2211 and the vertical connecting part 2212 are at a certain angle, the vertical connecting part 2212 of the tooling strip 221 can be placed on the cabinet 1 at a certain angle. Since the surface of the agitator 21 will retain residual heat and liquid after a long period of agitation, the tooling strip 221 is placed on the surface of the cabinet 1, and the agitator 21 is suspended, which can reduce contact with the operator. On the other hand, since the agitator 21 is installed on the tooling frame 22, placing the vertical connecting part 2212 on the cabinet 1 can make the center of gravity fall evenly on the cabinet 1, ensuring the stability of the connection between the connecting piece 14 and the vertical connecting part 2212 after a long period of use.

[0040] The tooling frame 22 also includes a handle 222, which is located at the end away from the connecting piece 14 and securely connects the two tooling strips 221; the position of the tooling frame 22 is adjusted by pulling up or lowering the handle 222.

[0041] The stirrer 21 is installed on the horizontal connecting part 2211 of the tooling strip 221. When the stirring mechanism 2 of the rosin high temperature furnace is working, the stirrer 21 is vertically facing the heating cylinder 12 and is connected to one end of the rotating shaft 23. The other end of the rotating shaft 23 is connected to the stirring impeller 24. The rotating shaft 23 and the stirring impeller 24 are vertically inserted into the heating cylinder 12.

[0042] The working process of this embodiment:

[0043] The worker adds rosin raw material into the heating cylinder 12 of a high-temperature furnace, lowers the fixture 22, and simultaneously inserts the stirrer 21 to stir the rosin while it is heating in the furnace. After the rosin is completely melted, the worker lifts the fixture 22 and places it on the cabinet 1. The worker places the filter assembly 3 on the opening of another heating cylinder 12, lifts the handles 122 on both sides of the outer wall of the heating cylinder 12, and pours the melted rosin through the filter assembly 3 into the other heating cylinder 12. After pouring, the worker puts the heating cylinder 12 of the high-temperature furnace back onto the original heater 11, adds new rosin raw material, lowers the fixture 22, inserts the stirrer 21, and continues heating and stirring.

[0044] Meanwhile, other auxiliary materials, such as solvents and antioxidants, are added to another heating cylinder 12. The tooling frame 22 is lowered, and the stirrer 21 is inserted to mix the materials evenly. After mixing, the final flux product is obtained. The staff then removes the flux from the heating cylinder 12.

[0045] In summary, the use of agitators 21 is relatively large in the actual production of rosin. In this application, agitators 21 are fixed on tooling frame 22, and tooling frame 22 is hinged to connecting piece 14. The insertion depth of agitators 21 can be changed by changing the angle between tooling frame 22 and connecting piece 14, which improves the ease of use. At the same time, multiple agitators 21 can be provided to stir the heating cylinder 12 at the same time, thereby improving the efficiency of agitator 21 and helping to meet production needs and improve the economic benefits of rosin production.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
