AI Technical Summary
Existing vacuum brazing solder drying equipment suffers from uneven hot air distribution when drying plate-shaped and columnar solders, resulting in uneven drying. In particular, the bottom of plate-shaped solders is poorly dried, and columnar solders can only revolve around the sun but cannot rotate on their own axis, which affects the drying speed.
A vacuum brazing solder drying device was designed, which includes an air inlet mechanism and a rotating placement mechanism. The plate-shaped solder is suspended at the bottom by ball bearings. Combined with the revolution and rotation driven by the motor, the hot air is evenly distributed and the drying efficiency is improved.
It achieves complete drying of the bottom and sides of plate-shaped solder, improving the drying effect, while columnar solder simultaneously revolves and rotates, enhancing the drying speed and uniformity.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, specifically a vacuum brazing solder drying device. Background Technology
[0002] Vacuum brazing utilizes capillary force to wet, spread, dissolve, diffuse, and fill gaps in liquid brazing filler metal on the surface of the base material to achieve the connection between parts. Before placing the solder into the vacuum furnace, it typically needs to be dried in a drying oven. A search revealed Chinese Patent Publication No. CN220602052U, which discloses a vacuum brazing solder drying device. This utility model provides a vacuum brazing solder drying device that can fix the solder and then rotate it for heating, avoiding uneven heating. The vacuum brazing solder drying device includes a protective chamber, a sealed door, an air inlet fan, a protective mesh, and an exhaust fan. The sealed door is rotatably connected to the front of the protective chamber, the air inlet fan is connected to the top of the protective chamber, protective meshes are connected to the lower left and right sides of the protective chamber, and an exhaust fan is connected to the lower rear side of the protective chamber.
[0003] While the above-mentioned technical solutions can drive the solder to rotate and heat, thus avoiding uneven heating of the solder, when drying plate-shaped solder, the bottom of the plate-shaped solder is in contact with the upper surface of the rotating disk, and hot air cannot blow over the bottom of the plate-shaped solder, which will affect the drying of the plate-shaped solder. Furthermore, when drying columnar solder, it can only drive the columnar solder to revolve around the central axis and cannot rotate on its own axis, which will affect the drying speed.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1:
[0022] like Figure 1 and Figure 4 As shown, a vacuum brazing solder drying device includes a box 1 for drying vacuum brazing solder. A door 6 is rotatably connected to the front hinge of the box 1. An air outlet is provided at the bottom rear side of the box 1. An air inlet mechanism 2 is installed through the top of the box 1. The air inlet mechanism 2 includes a blower 21 and an electric heating box 22 that are fixedly connected to the top of the box 1 in sequence. The air outlet of the blower 21 is connected to the interior of the electric heating box 22. A T-shaped tube 23 that penetrates the top of the box 1 is fixedly connected to the air outlet of the electric heating box 22. One end of the T-shaped tube 23 is located at the inner top of the box 1, and multiple air outlet holes 24 are provided on the outer surface of the T-shaped tube 23.
[0023] When in use, the electric heating box 22 can heat the air, and the blower 21 can blow hot air out through the air outlet 24 to dry the solder. After drying, the electric heating box 22 stops working, and the blower 21 can blow cold air in to cool the solder and speed up the cooling process.
[0024] Example 2:
[0025] like Figures 1 to 3 As shown, a base plate 3 is fixedly installed at the bottom of the housing 1. A first rotating placement mechanism 4 for placing vacuum brazing solder is installed on the top of the base plate 3. The first rotating placement mechanism 4 includes a support tube 41 rotatably connected to the top of the base plate 3. An annular placement plate 42 is fixedly connected to the top of the support tube 41. Multiple ball bearings 43 are rotatably embedded in the upper surface of the annular placement plate 42. Multiple side plates 44 are fixedly connected in an annular array to the upper surface of the annular placement plate 42. A first locking knob 45 is threaded through the outer surface of the side plates 44. A first motor 46 is fixedly installed on the upper surface of the base plate 3. A first gear 47 is fixedly connected to the output shaft of the first motor 46. An external gear ring 48 that meshes with the first gear 47 is fixedly sleeved on the outer surface of the support tube 41.
[0026] When drying the plate-shaped solder, the plate-shaped solder is placed above the annular placement plate 42. Then, the first locking knobs 45 are rotated to fix the plate-shaped solder and prevent it from falling off during rotation. The rotation of the first motor 46 drives the support tube 41 and the annular placement plate 42 to rotate through the first gear 47 and the external gear ring 48, thereby driving the plate-shaped solder to rotate. With the cooperation of the ball bearings 43, the top, bottom and sides of the plate-shaped solder can be dried comprehensively, improving the drying effect and solving the problem that the existing device is inconvenient to dry the bottom of the plate-shaped solder.
[0027] Example 3:
[0028] like Figures 1 to 3 As shown, a second rotary placement mechanism 5 for placing vacuum brazing solder is installed inside the first rotary placement mechanism 4. The second rotary placement mechanism 5 includes a second motor 51 fixedly connected to the upper surface of the base plate 3. The output shaft of the second motor 51 is fixedly connected to a rotating shaft 52. A turntable 53 is fixedly connected to the top end of the rotating shaft 52. Multiple placement tubes 54 are rotatably connected to the upper surface of the turntable 53. A second gear 55 is fixedly connected to the outer surface of the placement tube 54. An internal gear ring 56 that meshes with the second gear 55 is fixedly connected to the inner wall of the annular placement plate 42. Multiple second locking knobs are threaded through the annular array on the outer surface of the placement tube 54.
[0029] When drying columnar solder, the bottom end of the columnar solder is inserted into the placement tube 54, and then the second locking knob is turned to fix the columnar solder. Then, the second motor 51 is started to drive the rotating shaft 52 and the turntable 53 to rotate. Under the action of the second gear 55 and the internal gear ring 56, the placement tube 54 and the columnar solder can be driven to revolve and rotate, so as to fully dry the columnar solder. This solves the problem that the existing device can only drive the columnar solder to revolve but cannot rotate, which affects the drying speed.
[0030] Working principle: When in use, the electric heating box 22 can heat the air, and the blower 21 can blow hot air out through the air outlet 24 to dry the solder. After drying, the electric heating box 22 stops working, and the blower 21 can blow cold air in to cool the solder and speed up the cooling process.
[0031] When drying the plate-shaped solder, the plate-shaped solder is placed above the annular placement plate 42. Then, the first locking knobs 45 are rotated to fix the plate-shaped solder and prevent it from falling off during rotation. The rotation of the first motor 46 drives the support tube 41 and the annular placement plate 42 to rotate through the first gear 47 and the external gear ring 48, thereby driving the plate-shaped solder to rotate. With the cooperation of the ball bearings 43, the top, bottom and sides of the plate-shaped solder can be dried comprehensively, improving the drying effect and solving the problem that the existing device is inconvenient to dry the bottom of the plate-shaped solder.
[0032] When drying columnar solder, the bottom end of the columnar solder is inserted into the placement tube 54, and then the second locking knob is turned to fix the columnar solder. Then, the second motor 51 is started to drive the rotating shaft 52 and the turntable 53 to rotate. Under the action of the second gear 55 and the internal gear ring 56, the placement tube 54 and the columnar solder can be driven to revolve and rotate, so as to fully dry the columnar solder. This solves the problem that the existing device can only drive the columnar solder to revolve but cannot rotate, which affects the drying speed.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
