In other words, a laser providing unit (not shown) can provide the laser light R1 and penetrate the optical lens group 110. The optical lens group 110 includes a focusing lens 112 and a protective lens 114. The protective lens 114 is located between the focusing lens 112 and the laminate unit 130.
噴嘴頭元件120面對工件W。層板單元130位於光學鏡組110與噴嘴頭元件120之間，詳細而言，層板單元130為一外形輪廓為圓形。層板單元130位於光學鏡組110之雷射光出口端，層板單元130內部設有一光學通道132，光學通道132為層板單元130內設置的孔洞所形成，光學通道132用以提供雷射光R1穿過，雷射光R1經由噴嘴頭元件120穿出以對工件W進行加工。 The nozzle head element 120 faces the workpiece W. The laminated plate unit 130 is located between the optical lens group 110 and the nozzle head element 120. In detail, the laminated plate unit 130 has a circular shape. The laminate unit 130 is located at the laser light exit end of the optical lens group 110. An optical channel 132 is provided inside the laminate unit 130. The optical channel 132 is formed by a hole provided in the laminate unit 130. The optical channel 132 is used to provide laser light R1. The laser light R1 passes through the nozzle head element 120 to process the workpiece W.
層板單元130的材質包含金屬層板。層板單元130設有一粉塵止擋部134，粉塵止擋部134鄰近於噴嘴頭元件120。 The material of the laminate unit 130 includes a metal laminate. The laminate unit 130 is provided with a dust stopper 134, which is adjacent to the nozzle head element 120.
在上述的配置之下，藉由在光學鏡組110與噴嘴頭元件120之間設置層板單元130，藉由層板單元130的設置而能阻擋加工過程產生的 金屬燻煙及噴渣，以保護光學鏡組110而不受汙染，進而能降低光學鏡組110被損毀的機率。 Under the above-mentioned configuration, by arranging the plate unit 130 between the optical lens group 110 and the nozzle head element 120, the metal plate fume and slag spray generated during the processing can be blocked by the arrangement of the plate unit 130, so that Protecting the optical lens group 110 from contamination, thereby reducing the probability of the optical lens group 110 being damaged.
此外，本實施例的層板單元130採用金屬所製成，除了承受較高的溫度而在高溫製程下仍能發揮阻擋的作用以外，金屬材質製成的層板單元130能重複清潔使用，藉以降低製程的成本。 In addition, the laminate unit 130 of this embodiment is made of metal. In addition to being able to withstand high temperatures and still play a blocking role under high temperature processes, the laminate unit 130 made of metal can be repeatedly cleaned and used, thereby Reduce process costs.
本實施例不限制層板單元130的型態，只要是在光學鏡組110與噴嘴頭元件120之間設置層板單元130均屬本發明的範疇。 This embodiment does not limit the type of the laminate unit 130, as long as the laminate unit 130 is provided between the optical lens group 110 and the nozzle head element 120, it is within the scope of the present invention.
詳細而言，第2A圖為第1圖中層板單元一實施例的示意圖。請參閱第1圖及第2A圖。 In detail, FIG. 2A is a schematic diagram of an embodiment of the laminate unit in FIG. 1. See Figures 1 and 2A.
光學通道132的孔徑大小能依據層板單元130之置放位置與光束錐度進行設計以達最大遮蔽率。第2A圖中的層板單元130設有一頂部131，頂部131鄰近於光學鏡組110，粉塵止擋部134之底部133遠離於光學鏡組110，該光學通道132的孔徑自頂部131至粉塵止擋部134之底部133為一漸縮孔洞，換言之，光學通道內壁132a為呈倒錐狀。 The aperture size of the optical channel 132 can be designed according to the placement position of the laminate unit 130 and the beam taper to achieve the maximum shielding rate. The laminate unit 130 in FIG. 2A is provided with a top portion 131, the top portion 131 is adjacent to the optical lens group 110, and the bottom portion 133 of the dust stop 134 is far away from the optical lens group 110. The aperture of the optical channel 132 is from the top 131 to the dust stop The bottom portion 133 of the blocking portion 134 is a tapered hole. In other words, the inner wall 132a of the optical channel has an inverted cone shape.
在本實施例中，層板單元130設有一中心軸X，中心軸X位於光學通道132之內部，光學通道內壁132a與層板單元130的中心軸X夾設一夾角θ1，該夾角θ1的角度範圍介於0度至45度之間。 In this embodiment, the laminated plate unit 130 is provided with a central axis X, and the central axis X is located inside the optical channel 132. The inner wall 132a of the optical channel and the central axis X of the laminated plate unit 130 include an included angle θ1. The angle range is between 0 and 45 degrees.
另外，粉塵止擋部134為一斜錐板，該斜錐板角度θ2的角度範圍介於0度至90度之間，舉例而言，該斜錐板角度θ2的角度為0度，則為一平板體(如第6圖及第7圖所示)，第2A圖中的粉塵止擋部134的外側至粉塵止檔部134的內側為一漸縮結構，如第2B圖所示，第2B圖為第1圖中層板單元一實施例的示意圖。層板單元130a中粉塵止擋部134a的外側至粉塵止檔部 134a的內側為一漸擴結構。斜錐板的斜率為正斜率(如第2A圖)或負斜率(如第2B圖)。上述層板單元的粉塵止擋部為一體成形。然，本發明不以此為限制，如第2C圖所示，第2C圖為第1圖中層板單元一實施例的示意圖。層板單元130b中的粉塵止檔部134b為由多個組件組合而成之一負斜率的負錐度架構。 In addition, the dust stopper 134 is an inclined cone plate, and the angle range of the angle θ2 of the inclined cone plate is between 0 degrees and 90 degrees. For example, if the angle of the inclined cone plate angle θ2 is 0 degrees, then A flat body (as shown in Figs. 6 and 7), the outer side of the dust stopper 134 to the inner side of the dust stopper 134 in Fig. 2A is a tapered structure, as shown in Fig. 2B. FIG. 2B is a schematic diagram of an embodiment of the laminate unit in FIG. 1. In the layer unit 130a, the outer side of the dust stopper 134a to the inner side of the dust stopper 134a is a gradually expanding structure. The slope of the oblique cone plate is either a positive slope (as shown in Figure 2A) or a negative slope (as shown in Figure 2B). The dust stop portion of the laminate unit is integrally formed. However, the present invention is not limited to this. As shown in FIG. 2C, FIG. 2C is a schematic diagram of an embodiment of the laminate unit in FIG. 1. The dust stopper 134b in the laminate unit 130b is a negative taper structure with a negative slope formed by combining a plurality of components.
第3圖為本發明的保護裝置一實施例的示意圖。請參閱第3圖。第3圖的保護裝置20與第1圖的保護裝置10相似，其中相同的元件以相同的標號表示且具有相同的功效而不再重複說明，以下僅說明差異處。 FIG. 3 is a schematic diagram of an embodiment of a protection device according to the present invention. See Figure 3. The protection device 20 in FIG. 3 is similar to the protection device 10 in FIG. 1, in which the same elements are denoted by the same reference numerals and have the same functions without repeated description. Only the differences will be described below.
第3圖與第1圖的不同之處在於，保護裝置20更包括供粉料管140與送粉單元150。所述供粉料管140的數目至少為一個，供粉料管140連接於對應的噴嘴頭元件120。所述送粉單元150分別耦接於對應的供粉料管140。如第3圖所示，兩供粉料管140前端之間具有一角度，換言之，供粉料管140並非垂直於工件W，而是供粉料管140相對於工件W呈一傾斜配置，然，本實施例不對此角度加以限制，端視實際設備產品而能調整供粉料管的配置態樣。送粉單元150用以提供粉體至對應的供粉料管140內，透過供粉料管140所提供的粉體朝工件W的方向落下而形成一粉末流場R2，經雷射光R1以加熱粉末流場R2內的粉體，而被加熱後的粉體掉落至工件W或雷射光R1加熱工件W形成融池後，粉體掉落至該融池而達到熔覆效果。 The difference between FIG. 3 and FIG. 1 is that the protection device 20 further includes a powder supply pipe 140 and a powder feeding unit 150. The number of the powder supply pipes 140 is at least one, and the powder supply pipes 140 are connected to the corresponding nozzle head elements 120. The powder feeding units 150 are respectively coupled to corresponding powder supply tubes 140. As shown in FIG. 3, there is an angle between the front ends of the two powder supply tubes 140, in other words, the powder supply tube 140 is not perpendicular to the workpiece W, but the powder supply tube 140 is arranged at an angle with respect to the workpiece W, but In this embodiment, the angle is not limited, and the configuration of the powder supply pipe can be adjusted depending on the actual equipment product. The powder feeding unit 150 is used to supply powder into the corresponding powder supply pipe 140, and the powder provided by the powder supply pipe 140 falls toward the workpiece W to form a powder flow field R2, which is heated by the laser light R1 The powder in the powder flow field R2, and the heated powder falls to the workpiece W or the laser light R1 heats the workpiece W to form a melting pool, and the powder falls to the melting pool to achieve the cladding effect.
在此配置之下，於上述熔覆製程對粉體加熱過程所產生的大量噴濺的熔渣與金屬燻煙會被層板單元130所遮擋，以避免噴濺的熔渣與金屬燻煙汙染到光學鏡組110，進而能降低光學鏡組110被損毀的機率，也能降低整體熔覆製程之成本。 Under this configuration, a large amount of spattered slag and metal fume generated during the heating process of the powder by the above-mentioned cladding process will be blocked by the laminate unit 130 to avoid the spattered slag and metal fume pollution. Going to the optical lens group 110 can further reduce the probability of the optical lens group 110 being damaged, and also reduce the cost of the overall cladding process.
需說明的是，如第3圖所示的實施例中，是以熔覆製程作為舉例，然本發明的保護裝置不限制於此，本發明的保護裝置還可應用在如切割製程或焊接製程。 It should be noted that, in the embodiment shown in FIG. 3, a cladding process is taken as an example. However, the protection device of the present invention is not limited to this. The protection device of the present invention can also be applied to, for example, a cutting process or a welding process. .
第4圖為本發明的層板單元一實施例的示意圖。請參閱第4圖。第4圖的層板單元130d與第3圖的層板單元130相似，其中相同的元件以相同的標號表示且具有相同的功效而不再重複說明，以下僅說明差異處。 FIG. 4 is a schematic diagram of an embodiment of a laminate unit according to the present invention. See Figure 4. The layer unit 130d of FIG. 4 is similar to the layer unit 130 of FIG. 3, in which the same components are denoted by the same reference numerals and have the same functions without repeated description. Only the differences will be described below.
第4圖與第3圖的不同之處在於，層板單元130d更包括一吹氣通道160，吹氣通道160設於層板單元130d內，換言之，即將第1圖或第3圖中的層板單元130換成第4圖的層板單元130d，本實施例的層板單元130d亦可視實際情況而可選擇如第2A圖、第2B圖與第2C圖層板單元的配置方式。 The difference between FIG. 4 and FIG. 3 is that the layer unit 130d further includes an air blowing channel 160, and the air blowing channel 160 is provided in the layer unit 130d. In other words, the layer in FIG. 1 or FIG. The board unit 130 is replaced with the board unit 130d of FIG. 4, and the board unit 130d of this embodiment can also be selected according to the actual situation, such as the layout of the board unit of FIG. 2A, FIG. 2B, and 2C.
吹氣通道160貫穿於層板單元130d的內部，從層板單元130d外側邊緣開槽。 The air blowing channel 160 penetrates the inside of the layer unit 130d, and is slotted from the outer edge of the layer unit 130d.
在此配置之下，本實施例得以藉由吹氣通道160，使得吹氣通道160得以朝噴嘴頭元件120(參閱第3圖)的方向提供氣流，使飄進噴嘴頭元件120內之粉塵形成紊流，進而更容易讓粉塵附著至層板單元130d之粉塵止擋部134d，並能藉由粉塵止擋部134d之斜錐板結構，讓粉塵能自粉塵止擋部134d之邊緣落下，而不會從光學通道132中流入，以達到遮擋粉塵的目的。 With this configuration, the present embodiment is able to provide air flow in the direction of the nozzle head element 120 (see FIG. 3) by the air blowing channel 160, so that the dust floating into the nozzle head element 120 is formed. The turbulent flow makes it easier for dust to adhere to the dust stop 134d of the laminate unit 130d, and the slanted cone structure of the dust stop 134d allows the dust to fall from the edge of the dust stop 134d, and It will not flow in from the optical channel 132 to achieve the purpose of shielding dust.
第5圖為本發明的層板單元一實施例的示意圖。請參閱第5圖。第5圖的層板單元130e與第4圖的層板單元130d相似，其中相同的元件以相同的標號表示且具有相同的功效而不再重複說明，以下僅說明差異處。 FIG. 5 is a schematic diagram of an embodiment of a laminate unit according to the present invention. See Figure 5. The layer unit 130e of FIG. 5 is similar to the layer unit 130d of FIG. 4, in which the same components are denoted by the same reference numerals and have the same functions without repeated description. Only the differences will be described below.
第5圖與第4圖的不同之處在於，層板單元130e更包括一冷卻 水路元件170，冷卻水路元件170設於層板單元130e內，換言之，即將第1圖或第3圖中的層板單元130換成第5圖的層板單元130e，而第5圖中的粉塵止擋部134e與前述第4圖粉塵止擋部134d的結構與功能類似，在此不重複贅述。本實施例的層板單元130e亦可視實際情況而可選擇如第2A圖、第2B圖與第2C圖層板單元的配置方式。 The difference between FIG. 5 and FIG. 4 is that the layer unit 130e further includes a cooling water path element 170, and the cooling water path element 170 is provided in the layer unit 130e. In other words, the layer in FIG. 1 or FIG. The plate unit 130 is replaced with the laminated plate unit 130e in FIG. 5, and the dust stop portion 134e in FIG. 5 is similar in structure and function to the dust stop portion 134d in FIG. The layer unit 130e of this embodiment may also be selected according to the actual situation, such as the arrangement modes of the layer units of FIG. 2A, FIG. 2B, and 2C.
在此配置之下，除了前述吹氣通道160之功效以外，本實施例得以藉由冷卻水路元件170提供冷卻水來對層板單元130e降溫，藉以避免層板單元130e溫度過高，進而有效延長層板單元130e的使用壽命。 Under this configuration, in addition to the effect of the aforementioned air blowing channel 160, this embodiment can cool the laminate unit 130e by providing cooling water through the cooling water path element 170, thereby avoiding the excessive temperature of the laminate unit 130e, thereby effectively extending The life of the laminate unit 130e.
第6圖為本發明的層板單元一實施例的示意圖。請參閱第6圖。第6圖的層板單元130f與第5圖的層板單元130e相似，其中相同的元件以相同的標號表示且具有相同的功效而不再重複說明，以下僅說明差異處。 FIG. 6 is a schematic diagram of an embodiment of a laminate unit according to the present invention. See Figure 6. The layer unit 130f of FIG. 6 is similar to the layer unit 130e of FIG. 5, in which the same components are denoted by the same reference numerals and have the same functions without repeated description.

進一步地，層板單元的粉塵止檔部設計成一斜錐板，使得粉塵能自粉塵止擋部之邊緣落下，而不會從光學通道中流入，以提升遮擋粉塵的目的。 Further, the dust stop portion of the laminate unit is designed as an oblique cone plate, so that the dust can fall from the edge of the dust stop portion without flowing from the optical channel, so as to enhance the purpose of shielding the dust.
此外，本實施例的層板單元採用金屬所製成，除了承受較高的溫度而在高溫製程下仍能發揮阻擋的作用以外，金屬材質製成的層板單元能重複清潔使用，藉以降低製程的成本。 In addition, the laminate unit of this embodiment is made of metal.

進一步地，本實施例的層板單元內更可配置吹氣通道，使得吹氣通道得以朝噴嘴頭元件的方向提供氣流，使飄進噴嘴頭元件內之粉塵形成紊流，進而更容易讓粉塵附著至層板單元之粉塵止擋部，而不會從光學通道中流入，以達到遮擋粉塵的目的。 Further, the laminate unit in this embodiment may further be provided with an air blowing channel, so that the air blowing channel can provide airflow in the direction of the nozzle head element, so that the dust floating into the nozzle head element forms a turbulent flow, and it is easier to let the dust The dust stopper attached to the laminate unit does not flow from the optical channel to achieve the purpose of shielding dust.
進一步地，本實施例的層板單元內更可配置冷卻水路元件，藉由冷卻水路元件提供冷卻水來對層板單元降溫，藉以避免層板單元溫度過高，進而有效延長層板單元的使用壽命。 Further, the laminate unit in this embodiment may further be provided with a cooling water circuit element, and the cooling water circuit element provides cooling water to cool the laminate unit, thereby avoiding the excessive temperature of the laminate unit, thereby effectively extending the use of the laminate unit. life.
進一步地，由於粉體為金屬粉粒，本實施例的層板單元內更可配置磁性元件，藉由磁性元件的吸附而使得金屬粉粒容易附著在層板單元上，而不會讓金屬粉粒流入至雷射光路通道，進而能降低汙染光學鏡組的機率。 Further, since the powder is metal powder particles, a magnetic element can be further arranged in the layer unit of this embodiment, and the metal powder particles can be easily attached to the layer unit by the adsorption of the magnetic element without letting the metal powder The particles flow into the laser light path, which can reduce the probability of contaminating the optical lens group.
於一應用例中，可將保護裝置中的光學鏡組與層板單元分別配置於殼體內，噴嘴頭元件位於殼體外，供粉料管連接於噴嘴頭元件。如此一來，送粉單元提供粉體至對應的供粉料管內，透過供粉料管所提供的粉體朝工件的方向落下，並經雷射光加熱以達到熔覆效果。於上述熔覆製 程中層板單元能遮擋對粉體加熱過程所產生的大量噴濺的熔渣與金屬燻煙，以避免噴濺的熔渣與金屬燻煙汙染到光學鏡組，進而能降低光學鏡組被損毀的機率，也能降低整體熔覆製程之成本。此外，於此應用例中，更可配置氣體通道來提供保護氣體以保護光學鏡組，或者更可配置冷卻水路系統來降低整體裝置溫度。 In an application example, the optical lens group and the lamination unit in the protection device may be respectively arranged in a housing, the nozzle head element is located outside the housing, and the powder supply pipe is connected to the nozzle head element. In this way, the powder feeding unit provides powder to the corresponding powder supply tube, and the powder provided through the powder supply tube falls in the direction of the workpiece and is heated by laser light to achieve the cladding effect. During the cladding process, the lamination unit can shield a large amount of slag and metal fume generated during the heating process of the powder, so as to prevent the slag and metal fume from being sprayed from contaminating the optical lens group, thereby reducing the optical quality. The chance of the lens group being damaged can also reduce the cost of the overall cladding process. In addition, in this application example, a gas channel can be configured to provide a protective gas to protect the optical lens group, or a cooling water system can be configured to reduce the overall device temperature.
