New description: c. The technical field of the new households is related to a rotary spray cleaning and blow drying device. It is applied to the solder paste printing plate 5 and circuit board of SMT electronic products manufacturing. Red plastic cleaning. More specifically, it is related to the positional design of the nozzles provided on the rotating spray bars of the rotary spray cleaning device. Spring 【关^iiu老】 10 Cleaning equipment for printed steel plates and circuit boards is divided into two categories, one is ultrasonic vibration cleaning equipment, and the other is spray cleaning equipment. Among them, the spray cleaning equipment can be divided into two types: electric and fluid-driven spray cleaning equipment. Conventional printed steel plates and circuit board cleaning equipment require the use of volatile flammable solvents, while fluid-driven spray cleaning equipment requires only a pressurized fluid source to operate all of the entire equipment without any _ power. Therefore, it is possible to eliminate the risk of detonating the solvent due to the electric spark. Therefore, it is widely welcomed by many SMT electronics manufacturers. As shown in Fig. 1, a general fluid-driven spray cleaning device 20 has a cleaning tank 1 供 for the steel plate to be placed upright, and a rotating spray bar 12 is disposed on both sides of the cleaning tank. The upper portion is provided with a plurality of nozzles 16 at an angle of about 45 degrees to the steel plate, and the rotary spray bar is introduced into the flammable volatile cleaning solvent from the volatile cleaning solvent source tube 14 and sprayed from the nozzle to the steel plate. When the solvent is sprinkled, the reaction force of 25 will cause a lateral force applied to the spray bar to cause M31043 8 m. 9.22 to correct the rotation of the spray bar. More specifically, such a conventional rotary spray bar has a configuration as shown in Figs. 2A and 2B.
參照第2A與2B圖，其中第2A圖描述一種習知 旋轉喷灑棒的分解示意圖，而第2B圖描述該習知旋轉 噴灑棒的剖視圖。如該等圖式所示，習知的旋轉噴灑棒 包含有一旋轉軸心20、一旋轉本體22與一固定板24， 其中該旋轉軸心20之一端設有清洗溶劑來源管14並在 其之另一端設有凹槽18，同時於該凹槽内設有數個與 該清洗溶劑來源管14内部相連之通孔3〇，此外在該旋 轉軸〜的凹槽18之靠近該清洗溶劑來源管一側上另設 有一凸緣28。該旋轉本體係具有一配設於該旋轉軸心 之環狀外型，且其係被夾設於固定板24與該凸緣28之 間。該固定板24係藉由數個固定件26而被固定於在該 方疋轉軸心20之該清洗溶劑來源管的另外一端上。該旋 轉本體上進一步設有數個具有中空通道之喷灑棒12, 族等中空通道係與該旋轉轴心的凹槽18相通連，且該 方疋轉喷灑棒上進-步設有數個與該中空通道相通連之 喷嘴16藉由此等結構，來自清洗溶劑來源管μ之清 洗溶劑會經過該等通孔30流至旋轉軸心20之凹槽18, 〇接者流動至噴灑棒12之中空通道再由該等喷嘴16喷灑 至待清洗的鋼板上。 、 此種噴灑方式因為該旋轉喷灑棒之力道係 由喷嘴之反作用力來驅動，所以其之噴嘴—般係以偏離 該欲被清洗之鋼板之垂直方向而設置以有效地驅動該 6 M31043 8 ^ 年 /i 旋轉噴灑棒。然而’參見第3圖，其概略描述此種習知 的旋轉嘴灑棒的贺灑乾圍。如第3圖所示，其中喷嘴 16a、16b與16c係如上所述均係以與該鋼板成大約45 度的角度而設置，因此其之噴灑平面與鋼板的接觸區域 5 Ϊ、Π與111並未通過該旋轉喷灑棒的旋轉中心。因此， 此種習知的旋轉喷灑棒將會產生會形成介於大圓B(以 接觸區域I、II與III距離旋轉軸心C最遠之點D與旋 春 轉軸心C之距離為半徑，繞旋轉轴心c為圓心所形成 之圓）與小圓A(以接觸區域I、η與in距離旋轉轴心c 10最近之點E與旋轉軸心C之距離為半徑，繞旋轉軸心c 為圓心所形成之圓）之間的喷灑範圍。由第3圖可知， 此種旋轉喷灑棒的結構設計，將會面臨無法均勻地喷灑 旋轉軸心C周圍（即小圓A内部之區域）的缺點，因此 習知的旋轉喷灑棒必須花費更長的處理時間與更多的 15清洗溶劑’以使得旋轉軸心C周圍能達到足夠的清潔效Referring to Figures 2A and 2B, wherein Figure 2A depicts an exploded view of a conventional rotary spray bar, and Figure 2B depicts a cross-sectional view of the conventional rotary spray bar. As shown in the drawings, a conventional rotary spray bar includes a rotating shaft 20, a rotating body 22 and a fixing plate 24, wherein one end of the rotating shaft 20 is provided with a cleaning solvent source tube 14 and The other end is provided with a groove 18, and a plurality of through holes 3 connected to the inside of the cleaning solvent source tube 14 are disposed in the groove, and the groove 18 of the rotating shaft is adjacent to the cleaning solvent source tube. A flange 28 is further provided on the side. The rotary system has an annular outer shape disposed on the rotational axis and is interposed between the fixed plate 24 and the flange 28. The fixing plate 24 is fixed to the other end of the cleaning solvent source tube of the square rotating shaft 20 by a plurality of fixing members 26. The rotating body is further provided with a plurality of spray bars 12 having hollow passages, the hollow passages of the family and the like are connected to the grooves 18 of the rotating shaft center, and the square-turning spray rods are provided with a plurality of steps The nozzle 16 through which the hollow passage is connected is configured by the structure, and the cleaning solvent from the cleaning solvent source tube μ flows through the through holes 30 to the groove 18 of the rotating shaft 20, and the splicer flows to the spray bar 12 The hollow passages are then sprayed by the nozzles 16 onto the steel sheet to be cleaned. Since the force of the rotating spray bar is driven by the reaction force of the nozzle, the nozzle is generally disposed to deviate from the vertical direction of the steel plate to be cleaned to effectively drive the 6 M31043 8 ^ Year /i Rotate the spray bar. However, see Fig. 3, which schematically depicts the conventional dry sprinkler of the rotating sprinkler. As shown in Fig. 3, wherein the nozzles 16a, 16b and 16c are disposed at an angle of about 45 degrees to the steel plate as described above, so that the spray plane and the contact area of the steel plate are 5 Ϊ, Π and 111. The center of rotation of the rotating spray bar is not passed. Therefore, such a conventional rotary spray bar will produce a radius between the large circle B (the distance D between the contact regions I, II and III farthest from the rotation axis C and the rotation spring axis C). a circle formed by the center of the rotation axis c and a small circle A (the distance between the point E closest to the rotation axis axis 10 by the contact area I, η and in and the rotation axis C is a radius around the rotation axis c The range of spray between the circles formed by the center of the circle. As can be seen from Fig. 3, the structural design of such a rotary spray bar will face the disadvantage that it is impossible to uniformly spray the periphery of the rotating shaft center C (i.e., the area inside the small circle A), so the conventional rotary spray bar must Spend longer processing time with more 15 cleaning solvents' to achieve adequate cleaning around the rotating shaft C

[Embodiment 3] The concept of creation of the present invention is explained in detail in the following detailed description of the specific embodiments and the equivalents thereof. It should be noted that in order to clearly express the concept of the present invention, the drawings are not drawn to scale, and the specific embodiments are merely used to illustrate the concept of the present invention, and should not be used as a limitation. The basis for creation. Referring to Figure 4, there is shown a schematic view of the spray range of the M31043 8 nozzle arrangement in accordance with the present rotating spray bar. The rotary spray bar shown in Fig. 4 is provided with six nozzles, wherein one of the two nozzles 16c closest to the center of rotation of the rotary spray bar is sprayed in a direction The steel plate to be cleaned is vertical. As shown in Fig. 5 of the figure, since the three nozzles on the other arm of the arm of the nozzle having the vertically disposed nozzle are conventionally rotated as described above, the deviation is generally Set to the vertical direction of the steel plate to be cleaned. Therefore, φ, therefore, the contact area of the spray plane with the steel plate does not pass through the center of rotation of the rotating spray bar, but will be unable to uniformly spray around the 10 axis C (ie, the area inside the small circle) )Shortcomings. However, the vertically disposed nozzle 16c provided by the present invention can effectively spray the range (ie, the area inside the small circle G) by the spray plane III through which the spray plane III is sprinkled. The culvert cover rotates around the axis c and then starts to make the center of rotation more evenly sprayed. 15 Fig. 5 is a perspective view showing a specific example of another nozzle arrangement method of the rotary spray bar according to the present invention. As shown in the figure, it is shown that there are five nozzles on the spiral arm of each rotary spray bar, and the nozzle whose t is closest to the center of the rotary spray is perpendicular to the steel plate to be cleaned. The way the direction is set. Therefore, the 20-inch and sigh mode of the nozzle of the present invention can be changed according to the desired steel plate cleaning speed, the rotational speed of the rotating spray bar, and the consumption of the cleaning solution to achieve an optimal uniform cleaning effect and save. The amount of cleaning solution used. The innovative concepts described in this application can be applied to a wide range of applications (4). Therefore, the scope of this creation should not be limited to any specific typical teachings and specific examples discussed, but should be defined by the scope of the accompanying patent application. .
