Description of the invention (1) The present invention relates to a coating device, which can apply liquid, such as oil, to a workpiece, that is, to cover an object. In order to improve the lubricity and anti-corrosion protection, the electrical connector in the connector can be covered with a liquid with high viscosity, which is generally called contact oil (contact oi 1). The joint oil can be applied by liquid immersion or direct spraying. One coating method is to use liquid immersion technology for processing. The processing step is to prepare dilute oil and soak the workpiece in the dilute oil, and apply the oil to the workpiece. Among them, the preparation method of the diluent oil is to incorporate an organic solvent. Diluted in oil. As shown in Figs. 1 and 2, the workpiece 21, such as an elongated gold-plated ribbon member, is transferred from a supply roller 22 to a take-up roller 23 through a continuous plating device 31. The continuous electroplating apparatus 31 includes a pretreatment section 32 that performs a pretreatment operation, an electroplating section 33 that performs a plating step, an immersion coating section 34 that performs an immersion coating step, and a dehydration section 35 that performs a dehydration step. The immersion coating portion 34 is provided with an immersion coating device 34A, which can immerse and cover the workpiece 21 with dilute oil. A liquid tank 34B is disposed in the center of the immersion coater 34A, and a liquid is contained in the liquid tank 34B. Two pairs of transfer rollers 34C are arranged at both ends of the liquid tank 34B, one of which is on the left 'and the other is on the right. There are cooling pipes 34D above each pair of transfer rollers 34C. Immersion cover 34A 552163 V. Description of the invention (2) The upper part is connected with an air duct 34E. The liquid tank is filled with diluent oil, that is, the oil is combined with an organic solvent, such as a chlorine-containing solvent, and diluted to form a solution containing a volume ratio of about 0.1 to 20%. The dewatering section 3 5 has a dryer 3 5 A 'which can dehydrate and dry the workpiece 21 as shown in Fig. 1 and Fig. 2. The workpiece 21 is conveyed from the right to the left by the transfer rollers 34C on both sides. Workpiece 21—As it passes through the liquid tank 34B, it will be immersed and coated in dilute oil. Immediately after, the dryer 35A volatilizes only the organic solvent attached to the diluent oil of the workpiece 21. The coating method is to evenly apply a thin layer of oil to the workpiece by soaking in liquid. Therefore, the coating operation can be appropriately controlled, and the oil can be applied thinly and uniformly. However, it is because of the use of chlorine or similar solvents that the ozone layer is destroyed. Another coating method is to use a direct spraying technique to spray a liquid concentrated liquid directly onto the workpiece through a two-liquid sprayer to complete the coating work. As shown in Fig. 3, the two-liquid sprayer 41 is provided with oil and compressed gas, and the input end of the oil is a pressure tank 42 which is compressed by pressure. Both oil and compressed gas are mixed into the two-liquid sprayer 41 and become a mixed liquid, which is sprayed directly onto an object or workpiece 43. Therefore, the oil is coated on the workpiece 43 °. However, the coating method using the direct spraying technology makes the mist particles The distribution of size and flow rate appears uneven, but the range of variation is large. Because of 552163 V. Description of Invention (3) Therefore, it is difficult to control the covering operation in a very small range. In addition, due to the spraying operation, a large amount of oil is wasted due to the spray result. Summary of the Invention: Therefore, it is known from the above that one object of the present invention is to provide a coating device that can evenly coat a workpiece with a very small amount of coating even without using an organic solvent. Other objects of the present invention will be presented by the following description. According to the present invention, there is provided a covering device including a main sprayer, a spray box, and an auxiliary sprayer, wherein the main sprayer can inject liquid into the original mist, and the spray box is connected to the auxiliary sprayer and provided with the original mist, A fine mist containing small particles is generated, and the auxiliary sprayer is connected to the spray box to spray the fine mist on the workpiece.

Description of a preferred specific example: Fig. 4 is an illustration of a coating device according to a specific example of the present invention. From the description, it can be clearly understood that the coating device uses a mist blowing technology, and thus can be called a mist blowing coating device. The coating device in the picture can use a sprayer to spray a small amount of high viscosity joint oil. The covering device comprises a rectangular casing 1. A rectangular spray tank 2 is provided on the lower left side of the casing 1, and a main sprayer 3 is provided on the lower right side. The main sprayer 3 is suitable for mixing the liquid oil conveyed by the liquid tank (not shown) with the compressed gas, and spraying the mixture into the spray box 2 in a mist form through an injection port 3A to generate an original mist. The spray box 2 has an inner wall portion 2A facing the injection port 3A. The inner wall portion 2A isolates a liquefied portion from the original mist and retains only a fine mist with minute particles. A full description of this item is provided below. A gas inlet 2B is provided on the right side of the spray tank 2, and the inlet 2B is located above the other, and the other bottom inner wall is connected to an oil draining pipe 4, which is located on the right side of the place. An auxiliary sprayer 5 is provided on the upper inner wall of the spray box 2. The auxiliary sprayer 5 has a suction portion 5A that extends into the spray box 2 and a blow-out portion 5B that faces the workpiece 11 (for example, a connector in a connector) placed above the auxiliary sprayer 5.
552163 五、發明說明（5) 傳導接頭）。由技術中得知可用來作爲連接器內的傳導 接頭之工件。 輔助噴霧器5的加速部分5C是介於吸入部分5A與 吹出部分5B之間。加速部分5C提供有一壓縮氣體入 口 5D，該入口 5D位於該處的側邊。當啓動輔助噴霧 器5時，壓縮氣體則透過壓縮氣體入口 5D流進加速部 分5 〇 外殼1的入口 1 A及出口 1 B分別位於該處右側內壁 之上方及左側內壁之上方，皆可透過外殻1傳送工件 11。外殼1是連接至該處右側下方的集霧器。位於該 處中央部分的集油排泄管4則穿過外殼1的底部內 壁。 下列將說明將油噴塗至工件11之作業。主要噴霧 作業是利用主要噴霧器3將原始霧噴進噴霧箱2裡。 此時，當原始霧裡的大量霧粒子碰撞噴霧箱2的內壁 部分2A時，就會被液化，進而儲藏於噴霧箱2之下 方，成爲一種液化油。液化油是由集油排泄管4所集 中，以便排出至噴霧箱2及外殼1之外。因此，只有 少量的霧粒子保留於噴霧箱2內，成爲上述中的細 霧。集中的液化油可再次使用，因此即可降低因噴濺 結果而導致油的浪費。集油排泄管因此成爲液體排出 之方法。 另外’輔助噴霧作業是指輔助噴霧器5由噴霧箱2 552163 五、發明說明（6) 將細霧吸至吸入部分5A，再由吹出部分5B將細霧吹 出。由此，細霧即噴向工件11。也因此，噴霧箱2內 部則產生負壓力，以致氣體由壓縮氣體入口 5D進入到 輔助噴霧器。加速部分5C內的氣體含量則上升，以致 加速輔助噴霧作業，而且細霧被加速吹出。若於輔助 噴霧作業中提昇速度，則當細霧碰撞至工件1 1時，就 會造成強大的撞擊力。如此便會提高工件1 1接觸油的 濕潤度。因此，即使有細霧，以少量的油配合均勻且 薄的噴塗作業是可以實現的。 外殻1內存留的細霧是藉由集霧器6從外殻1排出 去。因此，集霧器6是作爲排霧之裝置。 第5圖及第6圖係針對直接噴霧技術與吹霧技術說 明實驗的條件與結果。 圖中，「直接噴霧」（1)至（3)是利用第3圖所例示 的被覆裝置，描述實驗的條件與結果。「吹霧」（1 )及 (2)是利用第4圖所例示的被覆裝置，描述實驗的條件 與結果。「氣壓」是描述由噴霧器41或主要噴霧器3 所吹出的壓縮氣體之壓力。「液體槽壓力」是描述油 流進噴霧器41或主要噴霧器3之壓力。「吹霧壓力」 是描述壓縮氣體流進輔助噴霧器5之壓力。 利用電子顯微圖，則觀察到工件的處理表面之外 觀。如果是吹霧（1)及（2)，則確定是以濃稠密度噴塗 直徑約10至20微米的微小粒子。在吹霧（1)及（2)情 552163 五、發明說明（7) 況，已確定油是均勻且少量地噴塗於工件上。與直接 噴霧（1 )至（3 )之每一種方式比較，在吹霧（1 )及（2 )情 況下，已確定油是均勻且少量地噴塗至工件。 雖然，本發明之說明與一些具體例相關聯，但是對 本業界技藝人士而言，可適當地將本發明融入於其他 各種方式。例如，有許多的主要噴霧器、許多輔助噴 霧器，以及許多噴霧箱皆可配置於殼內。再者，也可 將許多吸入部分5A以及許多吹出部分提供給一種單一 輔助噴霧器。無論是接頭油或是壓力油、切割油、潤 滑油等，均可用來作爲高黏度之液體；無論是連接器 的接頭或是各種物品，諸如條狀或蜂巢狀的連續金屬 板之產品，均可用來作爲待被覆之物體。 元件符號說明： 1…矩形外殻 1 A…入口 1B…出口 2…矩形噴霧箱 2A…內壁部分 2B…氣體入口 3…主要噴霧器 3A…注射口 4…集油排洩管 5…輔助噴霧器 552163 五、發明說明（8) 5A"· 吸入部分 5B"· 吹出部分 50·· 加速部分 5D… 壓縮氣體入口 6…集霧器 11，21，43···工件 22… 供應滾軸 23… 捲緊滾軸 31… 電鍍裝置 32… 預處理部分 33··· 電鍍部分 34"· 浸泡被覆部分 34A- …浸泡被覆器 34B· ••液體槽 34C- …傳輸滾軸 34D …冷卻管 34E· ••空氣導管 35··· 脫水部分 35A …乾燥器 41… 雙液噴霧器 42··· 壓力槽 -10-552163 V. Description of the invention (5) Conductive connector). It is known in the art that it can be used as a workpiece for a conductive joint in a connector. The acceleration portion 5C of the auxiliary sprayer 5 is interposed between the suction portion 5A and the blow-out portion 5B. The acceleration part 5C is provided with a compressed gas inlet 5D, which is located at a side edge there. When the auxiliary sprayer 5 is activated, the compressed gas flows into the acceleration part 5 through the compressed gas inlet 5D. The inlet 1 A and the outlet 1 B of the casing 1 are located above the right inner wall and above the left inner wall, respectively, and can pass through. The housing 1 conveys the workpiece 11. The housing 1 is a mist collector connected to the lower right side of the place. The oil collecting and draining pipe 4 located at the center of the place passes through the bottom inner wall of the casing 1. The operation of spraying oil to the work 11 will be described below. The main spraying operation is to spray the original mist into the spray box 2 using the main sprayer 3. At this time, when a large number of mist particles in the original mist collide with the inner wall portion 2A of the spray box 2, it will be liquefied and further stored under the spray box 2 to become a liquefied oil. The liquefied oil is collected by the oil collection drain pipe 4 so as to be discharged out of the spray tank 2 and the casing 1. Therefore, only a small amount of mist particles remain in the spray box 2 and become fine mist as described above. The concentrated liquefied oil can be reused, thus reducing oil wastage due to splash results. The oil drain pipe is therefore the method of liquid discharge. In addition, the “assisted spraying operation” means that the auxiliary sprayer 5 is sprayed by the spray box 2 552163 V. Description of the invention (6) The fine mist is sucked into the suction part 5A, and the fine mist is blown out by the blowing part 5B. As a result, a fine mist is sprayed onto the workpiece 11. Therefore, a negative pressure is generated inside the spray box 2, so that the gas enters the auxiliary sprayer from the compressed gas inlet 5D. The gas content in the acceleration portion 5C rises, so that the auxiliary spraying operation is accelerated, and the fine mist is accelerated out. If the speed is increased during the auxiliary spraying operation, when the fine mist hits the workpiece 11, a strong impact force will be caused. This will increase the wetness of the workpiece 1 1 in contact with the oil. Therefore, even with fine mist, a uniform and thin spraying operation with a small amount of oil can be achieved. The fine mist stored in the casing 1 is discharged from the casing 1 by the mist collector 6. Therefore, the mist collector 6 is a device for removing mist. Figures 5 and 6 illustrate the experimental conditions and results for the direct spray technology and the blowing technology. In the figure, "direct spray" (1) to (3) describe the experimental conditions and results using the coating device illustrated in Figure 3. "Blowing fog" (1) and (2) use the coating device illustrated in Figure 4 to describe the conditions and results of the experiment. "Air pressure" describes the pressure of the compressed gas blown out by the atomizer 41 or the main atomizer 3. "Liquid tank pressure" describes the pressure at which oil flows into the atomizer 41 or the main atomizer 3. "Blowing pressure" describes the pressure at which the compressed gas flows into the auxiliary sprayer 5. Using electron micrographs, the appearance of the treated surface of the workpiece was observed. In the case of mist blowing (1) and (2), it is determined that fine particles having a diameter of about 10 to 20 microns are sprayed in a dense density. In the case of blowing the mist (1) and (2) 552163 V. Description of the invention (7), it has been determined that the oil is uniformly and slightly sprayed on the workpiece. Compared with each of the methods of direct spraying (1) to (3), in the case of spraying the mists (1) and (2), it has been determined that the oil is uniformly and slightly sprayed to the workpiece. Although the description of the present invention is related to some specific examples, those skilled in the art can appropriately incorporate the present invention in various other ways. For example, there are many main sprayers, many auxiliary sprayers, and many spray tanks that can be placed in the housing. Furthermore, a plurality of suction portions 5A and a plurality of blowing portions may be provided to a single auxiliary sprayer. Whether it is joint oil or pressure oil, cutting oil, lubricating oil, etc., it can be used as a high-viscosity liquid; whether it is a connector joint or various items, such as strip or honeycomb continuous metal plates, Can be used as an object to be covered.
