Abstract
Description
本發明是有關於一種複合材料工件的製造方法，特別是指一種內埋磁性元件之複合材料工件的製造方法。The present invention relates to a method of manufacturing a composite workpiece, and more particularly to a method of manufacturing a composite workpiece in which a magnetic component is embedded.
現有較具質感之包裝材、行李箱，或是最近相當流行之平板電腦的保護套，皆是使用磁扣定位的方式來將開口處固定，以保護套為例，是在保護套的套體內埋設有一第一磁性件，而由該套體延伸出一定位帶，於該定位帶上對應該第一磁性件處設置一能與該第一磁性件相吸的第二磁性件，藉此當該第二磁性件靠近該第一磁性件時，兩者就能相吸而達到將保護套內之物品定位的作用。The existing more sensitive packaging materials, suitcases, or the protective sleeves of the most popular tablet PCs are all fixed by the magnetic buckle positioning method. For example, the protective sleeve is in the sleeve of the protective sleeve. A first magnetic member is embedded, and a positioning belt is extended from the sleeve, and a second magnetic member corresponding to the first magnetic member is disposed on the positioning belt corresponding to the first magnetic member, thereby When the second magnetic member is adjacent to the first magnetic member, the two can be attracted to each other to achieve positioning of the article in the protective cover.
然而，在以複合材料(例如預浸織布層)製造該保護套的過程中，是先於該套體及定位帶內分別設置有該第一磁性件及第二磁性件，然後再配合模具直接進行熱壓合，但在熱壓合過程中的高溫會導致該第一、二磁性件消磁而失去磁性定位的功能，為了解決上述問題，有業者是採用耐高溫之磁性元件，雖然可以克服高溫所導致的消磁問題，但耐高溫之磁性元件價格相當昂貴，使得生產成本大幅提高，不易普及使用。However, in the process of manufacturing the protective cover by a composite material (for example, a prepreg layer), the first magnetic member and the second magnetic member are respectively disposed in the sleeve and the positioning belt, and then the mold is matched. Direct thermocompression bonding, but the high temperature during the thermocompression process causes the first and second magnetic members to demagnetize and lose the magnetic positioning function. In order to solve the above problems, the manufacturer adopts a high temperature resistant magnetic component, although it can be overcome. The problem of degaussing caused by high temperature, but the high temperature resistant magnetic components are quite expensive, which makes the production cost greatly increased and is not easy to use.
因此，本發明之目的，即在提供一種可以降低生產成本的內埋磁性元件之複合材料工件的製造方法。Accordingly, it is an object of the present invention to provide a method of manufacturing a composite workpiece in which a buried magnetic component can reduce production costs.
於是，本發明內埋磁性元件之複合材料工件的製造方法，包含一堆疊步驟、一熱壓步驟，及一充磁步驟。該堆疊步驟是將多層預浸織布層對齊疊合，並將至少一個感磁元件置於所述預浸織布層上，再於該感磁元件上疊合多層預浸織布層；該熱壓步驟是將進行該堆疊步驟後的所述預浸織布層與該感磁元件熱壓合，將所述預浸織布層熱壓合成一複合材料工件，以使該感磁元件被包埋於該複合材料工件內；該充磁步驟是藉由通電至一線圈，使該線圈激磁產生磁場而感應該感磁元件，使該感磁元件充磁而轉變成一磁性元件。本發明之功效在於：藉由上述步驟，只要先使用感磁元件，待該複合材料工件成型後，再利用充磁的方式使感磁元件轉變成磁性元件，就能達成磁性定位的效果，不但能克服高溫消磁的問題，同時不需再使用昂貴的耐高溫磁性元件，而能大幅降低生產成本。Therefore, the method for manufacturing a composite workpiece with a buried magnetic component of the present invention comprises a stacking step, a hot pressing step, and a magnetizing step. The stacking step is to align the layers of the prepreg woven fabric, and place at least one magnetic sensitive component on the prepreg woven fabric layer, and then laminate the multilayer prepreg woven fabric layer on the susceptor component; The hot pressing step is: thermocompression bonding the prepreg woven fabric layer after the stacking step with the magnetic sensitive component, and hot pressing the prepreg woven fabric layer into a composite material workpiece, so that the magnetic sensitive component is Embedding in the composite workpiece; the magnetization step is performed by energizing a coil, causing the coil to generate a magnetic field to induce the magnetic component, and magnetizing the magnetic component to be converted into a magnetic component. The effect of the present invention is that, by the above steps, as long as the magnetic sensitive element is used first, after the composite workpiece is formed, and then the magnetic sensitive element is converted into a magnetic element by magnetization, the magnetic positioning effect can be achieved. It can overcome the problem of high temperature degaussing, and at the same time eliminate the need to use expensive high temperature magnetic components, which can greatly reduce production costs.
有關本發明之前述及其他技術內容、特點與功效，在以下配合參考圖式之一個較佳實施例的詳細說明中，將可清楚的呈現。The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.
參閱圖1，為本發明內埋磁性元件之複合材料工件的製造方法之較佳實施例，包含一堆疊步驟21、一熱壓步驟22，及一充磁步驟23。Referring to FIG. 1, a preferred embodiment of a method for fabricating a composite workpiece having a buried magnetic component according to the present invention includes a stacking step 21, a hot pressing step 22, and a magnetizing step 23.
參閱圖1與圖2，該堆疊步驟21是將多層預浸織布層3對齊疊合，並將多數個感磁元件4置於所述預浸織布層3上，再於所述感磁元件4上疊合多層預浸織布層3，於本實施例中，所述感磁元件4的材質為稀土金屬，而所述預浸織布層3是選自碳纖維織布、玻璃纖維織布、玄武岩纖維織布，或克拉纖維織布。另外，於本實施例中是使用多個感磁元件4，當然也可以視實際需求只使用一個感磁元件4，不以此為限。Referring to FIG. 1 and FIG. 2, the stacking step 21 is to vertically laminate the multi-layer prepreg layer 3, and place a plurality of magnetic sensitive elements 4 on the prepreg layer 3, and then the magnetic sensing. The multi-layer prepreg layer 3 is laminated on the element 4. In the embodiment, the material of the magnetic sensitive element 4 is rare earth metal, and the prepreg layer 3 is selected from the group consisting of carbon fiber woven fabric and glass fiber woven fabric. Cloth, basalt fiber woven fabric, or carat fiber woven fabric. In addition, in the present embodiment, a plurality of magnetic sensitive elements 4 are used. Of course, only one magnetic sensitive element 4 may be used depending on actual needs, and is not limited thereto.
該熱壓步驟22是將進行該堆疊步驟21後的所述預浸織布層3與所述感磁元件4配合模具(圖未示)進行熱壓合作業，俾將所述預浸織布層3壓合成一對應模具預設形狀之複合材料工件5，以使所述感磁元件4被包埋於該複合材料工件5內。The hot pressing step 22 is a hot pressing cooperation between the prepreg layer 3 and the magnetic component 4 (not shown) after the stacking step 21, and the prepreg is used. The layer 3 is pressed into a composite workpiece 5 corresponding to a predetermined shape of the mold such that the magnetic sensitive element 4 is embedded in the composite workpiece 5.
該充磁步驟23是藉由通電至一線圈(圖未示)，使該線圈激磁產生磁場而感應所述感磁元件4，使所述感磁元件4充磁而轉變成磁性元件6。由於該充磁過程與該線圈結構皆屬熟悉充磁技術之人士所能輕易實施，因此不再予以贅述其細節。The magnetization step 23 is performed by energizing a coil (not shown), causing the coil to generate a magnetic field to induce the magnetic sensitive element 4, and magnetizing the magnetic sensitive element 4 to be converted into the magnetic element 6. Since the magnetization process and the coil structure are easily implemented by those familiar with magnetization techniques, the details thereof will not be described again.
藉由上述步驟，只要先使用感磁元件4，待該複合材料工件5成型後，再利用充磁的方式使感磁元件4轉變成磁性元件6，就能達成磁性定位的效果，不需再使用昂貴的耐高溫磁性元件，而能大幅降低生產成本。By the above steps, as long as the magnetic sensitive element 4 is used first, after the composite material workpiece 5 is formed, and then the magnetic sensitive element 4 is converted into the magnetic element 6 by magnetization, the magnetic positioning effect can be achieved without the need for magnetic positioning. The use of expensive high temperature magnetic components can significantly reduce production costs.
綜上所述，本發明透過先進行該熱壓步驟22，再進行該充磁步驟23的方式，就能克服磁性材料在高溫後消磁的問題，同時也不需使用昂貴的特殊材料，有效降低生產成本，故確實能達成本發明之目的。In summary, the present invention overcomes the problem of demagnetization of the magnetic material after high temperature by performing the hot pressing step 22 and then performing the magnetizing step 23, and does not need to use expensive special materials, thereby effectively reducing The production cost is indeed achieved by the object of the present invention.
