Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an air knife structure for preventing chip-type electronic components from carrying materials during detection. Background Art

[0002] In the production and testing process of chip electronic components, ensuring the cleanliness of the component surface is crucial to product quality. Traditional air knife structures often have problems such as low efficiency, inaccurate air flow control, or structural design that is not conducive to maintenance and adjustment when removing excess materials (carrying materials) attached to the surface of components. Especially for precision electronic components, carrying materials not only affect the electrical performance of the components, but may also cause failures during the assembly process. Therefore, the market urgently needs an air knife structure that can efficiently and accurately control the airflow and easily adjust the direction to meet the needs of modern electronic manufacturing industry for high-precision and high-efficiency testing.

[0003] Deficiencies of existing technology:

[0004] 1. Insufficient air flow control accuracy: Traditional air knives may not be able to achieve precise guidance and adjustment of the air flow, resulting in poor results in removing material from the surface of components, easily damaging the components or incomplete removal.

[0005] 2. Limited structural flexibility: Most air knives are fixed in design and lack adjustability, making it difficult to flexibly adjust the outlet direction and airflow intensity according to different production requirements and component sizes.

[0006] 3. Inconvenient maintenance and installation: Some air knives have complex structures, making them difficult to disassemble, assemble, clean and maintain, which increases production downtime and maintenance costs.

[0007] 4. Compatibility and integration issues: The connection method with the external gas source may not be convenient enough, affecting the automation integration capability of the production line.

[0008] 5. Insufficient consideration of stability and durability: In a continuous operating environment, the wear and stability of key components such as the air knife's shaft and seal are not adequately designed, affecting its service life.

[0009] Therefore, the prior art has deficiencies and needs further improvement. Utility Model Content

[0054] Combination Figure 1-Figure 6 As shown, the utility model provides an air knife structure for preventing chip-type electronic components from carrying materials during inspection, comprising:

[0055] The base 1 has an air cavity inside.

[0056] The cover plate 2 is arranged on the base 1, and a gap between the cover plate 2 and the base 1 forms an air outlet 3;

[0057] The sealing ring 4 is arranged between the base 1 and the cover plate 2, and is sealed on three sides to leave one side for air outlet;

[0058] The base 1 is provided with a first base 5 for mounting a sealing ring 4 and a cover plate 2 which are stacked together;

[0059] The first base 5 is provided with a first air groove 6 arranged along the length direction of the base 1;

[0060] The base 1 is also provided with a second air groove 7 radially arranged on the side of the first air groove 6;

[0061] One end of the base 1 is also provided with a third air groove 8 arranged along the length direction of the base 1, and the third air groove 8 is connected with the second air groove 7, and further connected with the first air groove 6;

[0062] The third gas groove 8 is used for intake of gas, and then allows the gas to reach the second gas groove 7 and the first gas groove 6;

[0063] The cover plate 2 and the base 1 seal the upper and lower sides, and the sealing ring 4 is U-shaped and used to seal the second air groove 7 and the three sides of the first air groove 6, leaving one side as the air outlet 3 to form an air knife.

[0064] One end of the base 1 where the third air groove 8 is provided is provided with an air inlet port 9;

[0065] The air inlet port 9 is cylindrical.

[0066] The air inlet port 9 is also provided with a pipeline joint 10 for connecting to an external air source.

[0067] The other end of the base 1 is also provided with a rotating shaft 11;

[0068] The rotating shaft 11 and the air inlet port 9 are located on the same axis, and are used to rotatably mount the base 1 on an external bracket.

[0069] The base 1 is also provided with an adjustment hole 12 at one end of the rotating shaft 11 , in which a pin is arranged to limit the rotation of the base 1 .

[0070] A plurality of mounting holes 13 are provided on the first base 5 of the base 1 along the edges of the first air slot 6 and the second air slot 7 away from the air outlet 3 .

[0071] The cover plate 2 and the sealing ring 4 are also provided with corresponding through holes 14 at positions corresponding to the mounting holes 13, for fixing the cover plate 2 and the sealing ring 4 on the base 1 by screws.

[0072] The side of the base 1 away from the air outlet 3 is an arc-shaped surface 15, which is used to prevent the base 1 from colliding with the external bracket when rotating to adjust the direction of the air outlet 3.

[0073] The first base 5 and the cover plate 2 are both rectangular.

[0074] The principle of this utility model is as follows:

[0075] Airflow introduction and distribution: First, the external air source is connected to the cylindrical air inlet port 9 of the air knife structure through the pipe joint 10, and the airflow enters the third air slot 8. The airflow is guided in the third air slot 8 and then enters the second air slot 7 through the air path design. This process achieves preliminary airflow distribution and acceleration. Then, the airflow continues to pass through the first air slot 6. This series of air slot layouts forms an efficient airflow channel system, ensuring uniform distribution and acceleration of the airflow.

[0076] Precise airflow output and material removal: After being accelerated by the first and second air slots, the airflow is finally ejected at high speed from the tiny gap between the base 1 and the cover 2 (i.e., the air outlet 3). In this process, the U-shaped sealing ring 4 plays a key role. While keeping the three sides of the air slot sealed, it only leaves one side as an air outlet channel, forming a highly concentrated airflow "blade". This design can accurately blow away excess materials (materials) on the surface of chip electronic components without damaging the components themselves.

[0077] Structural flexibility and operational convenience: The base 1 is mounted on the external bracket via the rotating shaft 11, and the rotation range of the base 1 can be limited by adjusting the direction adjustment hole 12 on the rotating shaft 11 and the pin shaft set inside, so that the direction of the air outlet 3 can be adjusted according to actual needs, improving the flexibility and application range of the device. At the same time, the curved side design of the base 1 avoids interference with the external bracket during rotation adjustment, protecting the device from accidental damage.

[0078] Stable installation and easy maintenance: The preset installation holes 13 on the first base 5 and the corresponding through holes 14 on the cover plate 2 and the sealing ring 4 are fixed by screws to ensure the stability and sealing of the structure. This design facilitates daily assembly, adjustment and maintenance work, reducing the difficulty and cost of maintenance.

[0079] In summary, the air knife structure can effectively remove the surface material of chip electronic components through sophisticated air path design, rotation adjustment function and easy installation and maintenance, improve the efficiency and quality of pre-processing before inspection, and ensure flexibility and convenience of use.

[0080] The above description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the protection scope of the present invention.
