Description

Technical Field

[0001] This utility model relates to the technical field of an air blowing device, specifically an air blowing device. Background Technology

[0002] An air blowing device is a common industrial piece of equipment, typically consisting of a compressor, cylinder, piping, and nozzles. The compressor compresses air into high-pressure gas, which is then delivered to the cylinder. The gas in the cylinder drives a piston, creating an airflow. This airflow passes through the piping into the nozzle and is then ejected, blowing particles away from the target location.

[0003] Currently, the air blowing device used in the feed buffer turntable of active alignment (AA) equipment is a single-hole device, which has insufficient blowing strength and does not meet the requirements. Furthermore, defects with low relative illumination (LCB) values ​​in the inspection image show a ring-shaped tendency. Single-hole blowing can meet the requirements for small products, but it cannot meet the blowing requirements for larger products. This results in more particles adhering to the sensor. LCB defective products enter the machine for processing through the storage buffer turntable. The defective products produced are non-repairable, and in severe cases, there will be a batch of scrap, which will reduce the product defect rate, cause waste, and may lead to loss of customer trust, order cancellation, and loss of market competitiveness.

[0004] To address the shortcomings of existing technologies, this utility model provides an air blowing device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses an air blowing device, comprising:

[0007] The air blowing head body has a protrusion on its surface, and a plurality of air blowing holes are provided on the protrusion. A ventilation hole that works in conjunction with the air blowing holes is also provided on one side of the air blowing head body.

[0008] As a preferred embodiment of this utility model, the air blowing hole is located in the hollow part of the protrusion, and the interior of the air blowing head body is provided with a gas channel that communicates with the air blowing head and the air vent.

[0009] As a preferred technical solution of this utility model, the air blowing head body is provided with three air blowing holes.

[0012] As a preferred embodiment of this utility model, the diameter of the air holes located on both sides of the three air holes is smaller than the diameter of the air hole located in the middle position.

[0013] As a preferred embodiment of this utility model, the diameter of the air hole at the middle position is 1.5mm.

[0014] As a preferred embodiment of this utility model, the diameter of the air holes on both sides is 1.0 mm.

[0015] As a preferred embodiment of this utility model, the side of the air blowing head body is provided with mounting holes for installation and fixing.

[0016] As a preferred embodiment of this utility model, the mounting hole is provided with a threaded groove.

[0017] The beneficial effects of this utility model are:

[0018] 1. This type of air blowing device changes the single-hole air blowing mode to multi-hole air blowing, and through research and design of experiments (DOE) verification, it has been confirmed that three holes are the most suitable. Single-hole air blowing can only clean a part of the product area and cannot blow air onto the product in all directions. The three-hole air blowing device can blow air onto the product over a larger area, achieving a more effective particle removal effect.

[0019] 2. This blowing device, by being configured with three-hole blowing, has a better blowing width ratio and better gas flow tendency compared to other multi-hole blowing devices. Furthermore, the blowing intensity of the three-hole blowing device is higher than that of the single-hole blowing device, which better meets current usage requirements.

[0020] 3. Compared with single-hole blowing, this blowing device has a higher blowing intensity and is more effective at removing particles from products; compared with other multi-hole blowing devices, it has a higher blowing width ratio, is more suitable, and has a better blowing effect.

[0021] 4. This type of air blowing device improves the overall product yield and efficiency, reduces product LCB defects and scrap, and saves costs. Attached Figure Description

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides an air blowing device, comprising:

[0030] The air blowing head body 1 has a protrusion 2 on its surface. The air blowing head body 1 has multiple air blowing holes located on the protrusion 2, and a vent hole that works in conjunction with the air blowing holes is opened on one side of the air blowing head body 1. The air blowing holes are located in the hollow part of the protrusion, and the interior of the air blowing head body 1 has a gas channel that communicates with the air blowing head 3 and the vent hole. By setting multiple air blowing holes, it can be applied to larger products, meet the air blowing requirements of larger products, and blow air on the product from all directions, avoiding more particles adhering to the sensor.

[0031] The main body 1 of the blowing head is provided with three blowing holes. By setting three blowing holes, the single-hole blowing mode is changed to multi-hole blowing. After research and DOE verification, it was confirmed that the three-hole mode is the most suitable. The blowing width ratio of the three-hole blowing mode is better than that of other multi-hole modes, and the gas flow tendency is better. The blowing intensity of the three-hole blowing mode is higher than that of the single-hole mode, which is more in line with the current usage requirements.

[0032] The air inlet is circular and is a radially arranged through hole. By setting the air inlet as a radially circular through hole, the flow rate and uniformity of the airflow are ensured.

[0033] Among the three blowing holes, the diameter of the blowing holes on both sides is smaller than that of the blowing hole in the middle position. The diameter of the blowing hole in the middle position is 1.5 mm, and the diameter of the blowing holes on both sides is 1.0 mm. By setting the diameter of the blowing holes, if the blowing holes are too small, the gas flow may be insufficient, and the gas in the sample may not be fully blown out. If the blowing holes are too large, too much external impurities may be introduced, affecting the measurement results. At the same time, the uniformity of the gas is ensured, so that the gas is evenly distributed in the sample, thereby improving the accuracy of the measurement and avoiding the problem of too much or too little gas in some areas of the sample, which would affect the repeatability of the experimental results.

[0034] The main body 1 of the air blowing head has a mounting hole 4 on its side for installation and fixing. The mounting hole 4 has a threaded groove inside, and the mounting hole 4 is provided to facilitate the installation work.

[0035] During operation, the air is compressed to a certain pressure by the compressor. The compressed air enters the gas channel inside the blower head through the vent. The collision and elastic force between air molecules cause the air molecules to form a high-speed airflow. The high-speed airflow can be blown out through the blower hole on the blower head 3.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
