Description
本發明係有關於一種磁力輪,尤指一種能夠保護磁鐵環不受到腐蝕性化學物質侵蝕的抗蝕磁力輪。The invention relates to a magnetic wheel, in particular to a corrosion-resistant magnetic wheel capable of protecting a magnet ring from corrosive chemical substances.
齒輪乃係各類製造工業中相當常見的傳動件,然而在長時間的接觸作用下仍會產生磨損的問題,進而產生有微粒(particle),使得在電路板或是晶圓等製程中嚴重影響良率。因此,衍生出了磁力輪(Magnetic Gear)來代替齒輪作動,磁力輪不具有傳統齒輪的嚙齒,而是利用磁耦合力的相吸及相斥來達到傳動的目的。Gears are very common transmission parts in various manufacturing industries. However, under long-term contact, there will still be wear problems, and then particles will be generated, which will seriously affect the process of circuit boards or wafers. yield. Therefore, a Magnetic Gear is derived to replace the gear. The Magnetic Gear does not have the teeth of the traditional gear, but uses the attraction and repulsion of the magnetic coupling force to achieve the purpose of transmission.
一般的磁力輪通常是在金屬軸座裝上磁鐵環。然而,在一些具有酸鹼液體、酸鹼霧氣或是化學蒸氣的濕式製程中容易會造成金屬產生鏽蝕,或是在有酸洗或是化學清潔製程中的電路板和晶圓等產線,長期暴露於工作環境中的磁鐵環容易受到酸鹼物質或是腐蝕性化學物質的侵蝕,從而導致無法正常運作而需更換,故如何讓磁力輪能夠有效防蝕並永久運作不需更換乃亟待改善之缺弊。The general magnetic wheel is usually equipped with a magnet ring on a metal shaft seat. However, in some wet processes with acid-base liquids, acid-base mist or chemical vapors, it is easy to cause metal corrosion, or in production lines such as circuit boards and wafers in pickling or chemical cleaning processes, The magnet ring exposed to the working environment for a long time is easily corroded by acid and alkali substances or corrosive chemicals, which will cause it to malfunction and need to be replaced. Therefore, how to make the magnetic wheel effectively anti-corrosion and operate permanently without replacement is an urgent need to improve Shortcomings.

於本實施例中,軸座10為塑膠件,但本發明不以此為限,例如軸座10也可以為耐腐蝕的金屬件或其他耐腐蝕的材料所製成。軸座10包括一基座11及一軸桿12,軸桿12係自基座11的一側面縱向延伸而出。具體而言,基座11和軸桿12皆呈圓柱狀並具有相同的軸心,且軸桿12的直徑係小於基座11的直徑。軸座10具有一軸孔13,軸孔13係縱向貫穿基座11和軸桿12,以供軸座10可套接於一轉動軸(圖未示出)上。又,基座11還設有一定位孔14,定位孔14係自基座11的外緣貫穿至軸孔13,並且用以供一定位件(圖未示出)穿入以迫緊轉動軸而固定於軸座10上。於本實施例中,定位孔14為螺孔且定位件為螺栓,但本發明不以此為限,例如定位件也可以為插銷。另外,軸孔13也可以為非圓形孔,使得軸座10不需藉由定位件和定位孔14便可以和轉動軸形成緊密配合而不會打滑。In this embodiment, the
磁鐵環20為一環形的磁鐵,且本發明不對於磁鐵的磁性作限制,設計者可自行因應不同需求來作調整。磁鐵環20係套設於軸桿12上。磁鐵環20具有一外環面21及相對的二側平面22,且外環面21係連接在二側平面22之間。The
防蝕膜30係披覆在外環面21並且遮蔽各側平面22的至少一部份。於本實施例中,防蝕膜30可以為透過有機塗層、無機塗層、金屬塗層、表面硬化處理、陰極處理或陽極處理等所形成的保護層,但本發明不對此作限制,只要能夠有效防止腐蝕性化學物質的侵蝕即可,設計者亦可對應不同工作環境的需求來調整防蝕膜30的成分及厚度等。The
各密封環40係套設在軸桿12上並分別位於磁鐵環20的左右兩側,且各密封環40分別抵接各側平面22上的防蝕膜30。於本實施例中,密封環40為O型環,但本發明不以此為限。Each
側蓋環50係鎖接在軸桿12,並且朝著基座11縱向迫緊各密封環40及磁鐵環20,使得各密封環40緊密夾設在各側平面22的防蝕膜30上。於本實施例中,側蓋環50為塑膠件,但本發明不以此為限,例如側蓋環50也可以為耐腐蝕的金屬件或其他耐腐蝕的材料所製成,且側蓋環50較佳地和軸座10對應為相同材質以方便生產製造及組裝配置。側蓋環50的內緣設有一內螺紋51,軸桿12的末端設有一外螺紋15,內螺紋51係螺接外螺紋15而將側蓋環50鎖固在軸桿12上。較佳地,在內螺紋51及外螺紋15的表面上皆塗布有一螺紋密封劑A,使得內螺紋51和外螺紋15在螺接後透過固化的螺紋密封劑A完全密封,從而避免腐蝕性化學物質自螺紋處滲入。又,基座11及側蓋環50的外緣上分別設有相對的二夾持平面16、52,使得在將側蓋環50鎖固於軸桿12上時,能夠透過工具(如:鉗子)夾固在各夾持平面16、52上以方便施力鎖緊。The
進一步說明,基座11於軸桿12所延伸出的側面凹設有一環形槽17,側蓋環50朝向基座11的側面凹設有相對的另一環形槽53。各密封環40係分別容置於各環形槽17、53內,使得各密封環40不會直接裸露在外而受到腐蝕性化學物質的侵蝕。To further illustrate, the
值得注意的是,磁鐵環20具有一厚度t,每一密封環40具有一直徑D,每一環形槽17、53具有一寬度w及一深度d。於本實施例中,寬度w係大於直徑D,且直徑D係大於深度d,藉此各密封環40會凸出在各環形槽17、53外,使得側蓋環50在鎖固時磁鐵環20能夠接觸各密封環40以縱向迫緊,從而讓各密封環40產生彈性變形。又,防蝕膜30具有遮蔽側平面22的一遮蔽長度l。遮蔽長度l和1/2寬度w的總和係大於厚度t,藉此能夠確保各密封環40係抵接在防蝕膜30上而起到密封的效果,從而避免腐蝕性化學物質自防蝕膜30和密封環40之間滲入而腐蝕磁鐵環20。於本實施例中,遮蔽長度l係和磁鐵環20的厚度t等長,但本發明不以此為限。It should be noted that the
