Description

Technical Field

[0001] This utility model relates to the field of nitrogen blowing device technology, specifically a nitrogen blowing device with protective function. Background Technology

[0002] A nitrogen evaporator is a device that uses an external nitrogen compression tank to directionally blow nitrogen gas. Nitrogen protection is required in semiconductor eutectic bonding to prevent oxidation of the devices during the bonding process. In cleanrooms where semiconductors are used, air circulation is limited. To prevent rapid oxidation of the solder joints during bonding, the solder joints are covered with inert nitrogen gas, isolating them from direct oxygen contact and reducing oxidation.

[0003] Existing nitrogen evaporators directly blow nitrogen through tubing, making it difficult to flexibly adjust the nitrogen delivery position or the shape of the emitted nitrogen to suit different needs. With the miniaturization and diversification of semiconductor devices, solder joint locations have become more complex and varied, requiring precise nitrogen delivery to these locations. However, traditional nitrogen delivery methods are often fixed and cannot be flexibly adjusted to accommodate changes in solder joint location.

[0004] In summary, existing semiconductor welding processes have significant shortcomings in terms of oxidation prevention, operational flexibility, and equipment maintenance and storage. To improve the quality and efficiency of semiconductor welding and reduce production costs, it is essential to design a nitrogen evaporator with protective functions. This device can effectively address the problems of existing processes and provide a more reliable, flexible, and convenient protective solution for semiconductor welding. Utility Model Content

The cover assembly is located on top of the support assembly, the gas supply assembly is located on the outer ring of the adjustment mechanism, and the disassembly assembly is located on top of the cover assembly.

[0009] Preferably, the mounting assembly includes a threaded rod, which is fixedly connected to the left side of the frame plate. The outer ring of the threaded rod is threadedly connected to a threaded mounting seat, and a fixing rod is fixedly connected to the left side of the threaded mounting seat.

[0010] Preferably, the connecting assembly includes a ball valve one, which is fixedly connected to the left side of the fixed rod. The outer ring of the ball valve one is rotatably connected to a connecting sleeve one, and the bottom of the connecting sleeve one is rotatably connected to a connecting bearing.

[0011] Preferably, the support assembly includes a rocker arm, which is fixedly connected to the front side of the ball valve. A connecting collar is fixedly connected to the front side of the rocker arm. A rotating frame is rotatably connected to the inner ring of the connecting collar. A rotating block is fixedly connected to the top of the rotating frame. A rotating cylinder is rotatably connected to the outer ring of the rotating block.

[0012] Preferably, the cover assembly includes a fixed cylinder, which is fixedly connected to the top of the rotating cylinder. A sleeve frame is fixedly connected inside the fixed cylinder. An air supply cylinder is slidably connected to the inner ring of the sleeve frame. A connection port is fixedly connected to the rear side of the air supply cylinder. An air outlet head is fixedly connected to the front side of the air supply cylinder. A screen is fixedly connected to the inner ring of the air outlet head.

[0013] Preferably, the gas supply assembly includes a gas supply pipe, which is fixedly connected to the rear side of the float flow meter. The gas supply pipe is sleeved inside the frame plate, wrapped around the fixed rod and the outer ring of the rocker arm, and snapped into the outer ring of the connection port. A positioning collar is sleeved on the outer ring of the gas supply pipe, and a rotating ring is fixedly connected to the inner side of the positioning collar.

[0015] Compared with the prior art, this utility model provides a nitrogen blowing device with protective function, which has the following beneficial effects:

[0016] 1. This nitrogen blowing device with protective function has an adjustable mechanism. During use, the ball valve 1, connecting bearing, ball valve 2, and rotating block can all rotate. Ball valve 1 and ball valve 2 can rotate at all angles, while connecting bearing 2 and rotating block can rotate on a single axis. This allows the operator to adjust the position of the air supply cylinder as needed, so that the air outlet can be placed anywhere within the arm's allowable range. This improves the flexibility of the device and allows it to follow the welding torch to perform anti-oxidation treatment on the weld points.

[0017] 2. This nitrogen blowing device with protective function uses a gas delivery mechanism. The gas delivery cylinder is engaged within the frame. The operator only needs to rotate the dial to move the positioning pressure plate up and down, controlling the contact between the positioning pressure plate and the gas delivery cylinder. This allows the operator to change different sizes of gas outlet heads and different mesh screens as needed. Different gas outlet heads and screens will result in different trajectories of the sprayed nitrogen, changing the coverage area of ​​the nitrogen when blowing onto the weld joint. This provides greater flexibility in the use of the device. Compared to blowing nitrogen directly through a pipeline, it ensures that the nitrogen always covers the outside of the weld joint during welding, ensuring the isolation of the weld joint from the air and effectively preventing oxidation of the weld joint.

[0029] This utility model provides a technical solution:

[0030] Example 1

[0031] Combination Figures 1 to 7 A nitrogen blowing device with protective function includes a base 3, a frame plate 4 fixedly connected to the top of the base 3, a float flow meter 5 fixedly connected to the front side of the frame plate 4, an adjustment knob 51 fixedly connected to the front side of the float flow meter 5, an adjustment mechanism 1 provided on the left side of the frame plate 4, and a gas delivery mechanism 2 provided in front of the adjustment mechanism 1.

[0035] Example 2

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 Furthermore, based on Embodiment 1, the gas delivery mechanism 2 includes a cover assembly 21, a gas delivery assembly 22, and a disassembly assembly 23. The cover assembly 21 is disposed on the top of the support assembly 13, the gas delivery assembly 22 is disposed on the outer ring of the adjustment mechanism 1, and the disassembly assembly 23 is disposed on the top of the cover assembly 21.

[0037] The cover assembly 21 includes a fixed cylinder 2101, which is fixedly connected to the top of the rotating cylinder 1305. A sleeve frame 2102 is fixedly connected inside the fixed cylinder 2101. An air supply cylinder 2103 is slidably connected to the inner ring of the sleeve frame 2102. A connection port 2104 is fixedly connected to the rear side of the air supply cylinder 2103. An air outlet hood 2105 is fixedly connected to the front side of the air supply cylinder 2103. A screen 2106 is fixedly connected to the inner ring of the air outlet hood 2105. The air supply assembly 22 includes an air supply pipe 2201, which is fixedly connected to the rear side of the float flowmeter 5. The air supply pipe 2201 is sleeved inside the frame plate 4 and is wound around the fixed rod 1103 and the rocker arm 1301. The outer ring of the gas supply pipe 2201 is snapped into the outer ring of the connection port 2104. The outer ring of the gas supply pipe 2201 is fitted with a positioning collar 2202. A rotating ring 2203 is fixedly connected to the inner side of the positioning collar 2202. There are two rotating rings 2203. The two rotating rings 2203 are respectively rotatably connected to the outer ring of the fixed rod 1103 and the rocker arm 1301. The disassembly and assembly assembly 23 includes a threaded rotating shaft 2301. The threaded rotating shaft 2301 is threadedly connected to the top of the fixed cylinder 2101. A torsion plate 2302 is fixedly connected to the top of the threaded rotating shaft 2301. A positioning pressure plate 2303 is fixedly connected to the bottom of the threaded rotating shaft 2301. The positioning pressure plate 2303 is slidably connected to the inside of the fixed cylinder 2101.

[0038] Furthermore: The positioning collar 2202 is rotatably connected to the fixed rod 1103 and the outer ring of the rocker arm 1301 via the rotating ring 2203. The positioning collar 2202, which is fitted onto the outer ring of the gas pipe 2201, positions the gas pipe 2201, allowing the gas pipe 2201 to swing with the rocker arm 1301. The gas pipe 2201 itself will not become tangled, making it easier for staff to replace the gas pipe 2201 later.

[0039] In actual operation, when this device is in use and it is necessary to replace the fixed rod 1103 and the rocker arm 1301, the operator first pulls the right end of the air supply pipe 2201 backward to disconnect the air supply pipe 2201 from the float flow meter 5. Then the operator rotates the threaded mounting seat 1102. The threaded mounting seat 1102 rotates to the left on the outer ring of the threaded rod 1101 and disengages from the threaded rod 1101. At this time, the disassembly of the fixed rod 1103 and the rocker arm 1301 is completed.

[0040] When it is necessary to disassemble the air supply cylinder 2103, the worker first pulls the left end of the air supply pipe 2201 backward to disconnect the air supply pipe 2201 from the connection port 2104. Then, the worker rotates the torsion plate 2302. The rotation of the torsion plate 2302 drives the threaded shaft 2301 to rotate. The threaded shaft 2301 rotates and moves upward inside the top of the fixed cylinder 2101. The upward movement of the threaded shaft 2301 drives the positioning pressure plate 2303 to move upward. The positioning pressure plate 2303 moves upward and disengages from the air supply cylinder 2103, releasing the positioning of the air supply cylinder 2103. Then, the worker can move the air supply cylinder 2103 forward to disconnect the air supply cylinder 2103 from the sleeve 2102. At this time, the disassembly of the air supply cylinder 2103 is completed.

[0041] When it is necessary to install the air supply cylinder 2103, the worker first inserts the new air supply cylinder 2103 into the sleeve frame 2102, and then rotates the torsion plate 2302 to drive the positioning pressure plate 2303 to move downward. The positioning pressure plate 2303 moves downward and contacts the top of the air supply cylinder 2103. The positioning of the air supply cylinder 2103 is completed by squeezing the top of the air supply cylinder 2103. Finally, the worker connects the left end of the air supply pipe 2201 to the outer ring of the connector 2104. At this time, the installation of the new air supply cylinder 2103 is completed.
