Description
本發明是有關於一種量測裝置，特別是指一種能精確地量測液面高度的液面量測裝置及三維列印機。 The invention relates to a measuring device, in particular to a liquid level measuring device and a three-dimensional printing machine capable of accurately measuring the liquid level.
在3D列印(3D printing)的技術中，立體光固成型法(Stereolithography,SLA)為3D列印的其中一種方式。而利用SLA的3D列印機是於盛料容器內放入光敏樹脂，藉由該光敏樹脂接收相應的光波長而達固化成型。 Among the techniques of 3D printing, Stereolithography (SLA) is one of the methods of 3D printing. The 3D printer using SLA is to put a photosensitive resin into the container, and the photosensitive resin receives the corresponding wavelength of light to form a curing.
而在使用液體盛料容器時，使用者往往需隨時得知所盛裝之液體容積量(此後提到的液體意指為3D列印中的光敏樹脂)。對於該盛料容器，可使用簡易之標記方式，利用容積量與液面高度呈一線性關係或非線性關係之特性，於容器上標記液體至每個液面所表示之容積。藉此，使用者便可得知所盛裝之液體容積量。但此種測量方式較為不方便，因為使用者必須將視線水平對齊該液面，若視線稍微偏高或偏低，都會造成測量不精準，故於此類型之盛料容器，一般乃使用一液面量測裝置，利用可隨液面改變而產生角度變化之浮標，間接地測量液面高度，進而獲 得液體容積量之資訊。 When a liquid container is used, the user often needs to know the volume of the liquid contained therein (the liquid referred to hereinafter refers to the photosensitive resin in the 3D printing). For the container, a simple marking method can be used to mark the volume of the liquid to the volume indicated by each liquid level by using a linear or non-linear relationship between the volume and the liquid level. Thereby, the user can know the amount of liquid volume contained therein. However, this type of measurement is inconvenient because the user must align the line of sight horizontally to the liquid level. If the line of sight is slightly higher or lower, the measurement will be inaccurate. Therefore, a container of this type is generally used. The surface measuring device uses the buoy which can change the angle with the change of the liquid surface to indirectly measure the liquid level and obtain Get the information on the volume of liquid.
參閱圖1與圖2，現有的液面量測裝置適用於一液體儲存容器90，並包含一浮標91與一量測裝置92。該浮標91一端乃漂浮於液面，另一端則連結至該量測裝置92，且該浮標91可隨液面之變化而以樞軸93為中心轉動。該量測裝置92內包括一亦固定於該樞軸93且與該浮標91連動之支桿94。當該浮標91隨液面變化而轉動時，便帶動該支桿94於一電阻片95上往復移動。而該樞軸93與該電阻片95之一端分別連接至電性接點96與97。由於該樞軸93與該支桿94亦由導體材料所構成，故當於該電性接點96與97間施加一電壓時，便可形成如箭頭98所示之導通狀態，使電流由該電性接點96，通過該樞軸93、支桿94，及支桿94所在位置右側之電阻片95返回至該電性接點97。根據不同的液面高度導致的支桿94轉動，電阻片95在箭頭98方向上的傳導路徑長度會有所改變，因此從電性接點96至電性接點97之間的傳導路徑的電阻值會產生對應的變化。所以，使用者藉由測量電流強度，並進一步參照預先取得之電流強度與液體容積量關係，便可得知液體儲存容器90中所儲存之液體容積量。然而，當長期使用此種類型之液面量測裝置時，電阻片95往往會因支桿94之往復移動而快速磨損，故需定期更換量測裝置92中之電阻片95。 Referring to Figures 1 and 2, the conventional liquid level measuring device is suitable for a liquid storage container 90 and includes a buoy 91 and a measuring device 92. One end of the buoy 91 floats on the liquid surface, and the other end is connected to the measuring device 92, and the buoy 91 can rotate around the pivot 93 as the liquid surface changes. The measuring device 92 includes a strut 94 that is also fixed to the pivot 93 and interlocked with the buoy 91. When the buoy 91 rotates with the change of the liquid surface, the rod 94 is driven to reciprocate on a resistor sheet 95. The pivot 93 and one end of the resistor 95 are connected to the electrical contacts 96 and 97, respectively. Since the pivot 93 and the strut 94 are also made of a conductor material, when a voltage is applied between the electrical contacts 96 and 97, a conduction state as indicated by an arrow 98 can be formed, so that the current is caused by the current. The electrical contact 96 is returned to the electrical contact 97 through the pivot 93, the strut 94, and the resistive sheet 95 on the right side of the position of the strut 94. According to the rotation of the strut 94 caused by the different liquid level, the length of the conduction path of the resistor 95 in the direction of the arrow 98 is changed, so the resistance of the conduction path from the electrical contact 96 to the electrical contact 97 is changed. The value will produce a corresponding change. Therefore, the user can know the amount of liquid volume stored in the liquid storage container 90 by measuring the current intensity and further referring to the relationship between the previously obtained current intensity and the liquid volume. However, when such a type of liquid level measuring device is used for a long period of time, the resistor piece 95 tends to wear rapidly due to the reciprocating movement of the strut 94, so the resistor piece 95 in the measuring device 92 needs to be periodically replaced.
因此，由上述可知：習知液面量測裝置的結構不僅操作複雜，且長期使用該量測裝置易造成零件的磨損 ，進一步縮短產品的壽命。故現有的液面量測裝置仍有進一步改善的空間。 Therefore, it can be known from the above that the structure of the conventional liquid level measuring device is not only complicated to operate, but also the wear of the parts is easily caused by long-term use of the measuring device. , further shorten the life of the product. Therefore, there is still room for further improvement of the existing liquid level measuring device.

參閱圖9、圖12與圖13，特別要說明的是：在本實施例中，該光固化性液體100為光固化樹脂，當然也可為其他種類的成型液，並不以本實施例揭露為限。而該盛料容器3是先加入隔離液200於底層，再加入光固化性液體100於該隔離液200上，且該隔離液200是不會被消耗的，其目的是為了防止該光固化性液體100與該底壁31接觸，以避免雷射光束照射於該光固化性液體100而使其固化成型於該底壁31上。 Referring to FIG. 9 , FIG. 12 and FIG. 13 , in particular, in the embodiment, the photocurable liquid 100 is a photocurable resin, and of course, other types of molding liquids may be used, and the present embodiment is not disclosed in the embodiment. Limited. The material container 3 is first added with the spacer liquid 200 to the bottom layer, and then the photo-curable liquid 100 is added to the spacer liquid 200, and the spacer liquid 200 is not consumed, and the purpose thereof is to prevent the photocurability. The liquid 100 is in contact with the bottom wall 31 to prevent the laser beam from being irradiated onto the photocurable liquid 100 to be solidified on the bottom wall 31.
以下說明該三維列印機之量測液面高度的運作方式。 The operation of the measured liquid level of the three-dimensional printer will be described below.
首先，於該盛料容器3內加入隔離液200，此時該浮標435浮於該隔離液200之表面，並連動該量測臂43及該旋轉盤42轉動，使該感測器44感測該對應之刻度值，直到加入該隔離液200至一起始刻度值即可接著加入該光固化性液體100。而浮標435接著浮於該光固化性液體100之表面，漸漸加入該光固化性液體100至一最高刻度值或介於該最高刻度值與一最低刻度值之間，此時，該光固化性液體100之容量由使用者所需之成型需求來決定。然後即可進入3D列印，待該光固化性液體100之容量消耗至該最低刻度值時，即通知使用者應補充該光固化性液體100。 First, the spacer liquid 200 is added to the container 3, and the buoy 435 floats on the surface of the spacer liquid 200, and the measuring arm 43 and the rotating disk 42 are linked to rotate, so that the sensor 44 senses. The corresponding scale value is added to the photocurable liquid 100 until the spacer 200 is added to a starting scale value. The buoy 435 is then floated on the surface of the photocurable liquid 100, and the photocurable liquid 100 is gradually added to a maximum scale value or between the highest scale value and a lowest scale value. At this time, the photocurability The capacity of the liquid 100 is determined by the molding requirements desired by the user. Then, the 3D printing can be entered. When the capacity of the photocurable liquid 100 is consumed to the lowest scale value, the user is notified that the photocurable liquid 100 should be replenished.
由上述的該量測機構4及該連動機構5相配合，就構成一種液面量測裝置。 The above-described measuring mechanism 4 and the interlocking mechanism 5 cooperate to form a liquid level measuring device.
綜上所述，透過該浮標435形成於該第二臂段432之端部，且能浮於液體100之表面並隨液面10之高度作升降，並連動該量測臂43帶動該旋轉盤42旋轉，使該感測器44能感測該對應之刻度，以精準地量測液面10之高度，進而得知液體100之容積量，且運用不易磨損的零件與簡單的操作方式，搭配光學原理做準確的測量，不僅能夠增加零件的使用壽命，亦同時降低操作上的複雜度，故確實能達成本發明之目的。 In summary, the buoy 435 is formed at the end of the second arm segment 432, and can float on the surface of the liquid 100 and rise and fall with the height of the liquid surface 10, and the measuring arm 43 is linked to drive the rotating disc. The rotation of 42 enables the sensor 44 to sense the corresponding scale to accurately measure the height of the liquid surface 10, thereby knowing the volume of the liquid 100, and using the parts that are not easy to wear and the simple operation mode, The optical principle makes accurate measurements, which not only increases the service life of the parts, but also reduces the operational complexity, so that the object of the present invention can be achieved.
惟以上所述者，僅為本發明之較佳實施例而已 ，當不能以此限定本發明實施之範圍，即大凡依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。 However, the above is only the preferred embodiment of the present invention.
