-將每一緊固銷的一端製成镦頭,進而將刀片組 定在平板護罩上。 U 相應地,無論刀片的數量多少,將刀片組件3固定 平板護罩2上的步驟需在配置平板後蓋4之前完減。換^ 之’刀片組件3與平板後蓋4是各自獨立,分步安筆到二 板護罩2上的。因此,當枝後蓋4意外從平板^部: 2脫落時,不會引起刀片的散落。
另外’由於刀片元件3單獨固定在平板護罩2上,與 平板後蓋4相互分離,因而亦可使平板後蓋4更牢固地固' 定在平板防護組件2上。 還有,由於緊固銷16僅用來固定夾入緊固片的刀片 組件3,比通常要短,因而更為牢固,降低了刀片意外從 平板護罩2脫落的危險。 如圖2和圖5所示,當平板後蓋4固定於平板護罩2 之後,就將内腔體積8封閉,從而避免了收納其中的刀片 被觸及。 顯然,根據刀片的數目不同,平板護罩2的厚度,即 圍板7的高度需隨刀片組件3的厚度而變化。 如圖5所示,當刀片組件3被鉚緊後,镦頭54不會 從平板護罩2的内腔體積8内伸出,使得在將平板後蓋4 安裝於平板護罩2時,能夠緊貼平板護罩2的圍板7。 再如圖5所示,平板後蓋4被雷射熔接(iaser welding) 在平板護罩2上。雷射源通過一撓性雷射導向元件(f|exible laser beam guiding) 56 與雷射溶接頭(iaser welding head) 20053i66i9 Qc 55連接。雷轉接頭55固定在—操作杆(麵)π上, 該操作杆57配置在-失持裳置(dampingde_t)58上, 可沿與平板後蓋4和平板護罩2之間的介面(―) 59相垂直的方向往復滑動,如箭頭F1所示。另戚外,雷射 炼接頭55可相對於夾持裝置58纟與平板後蓋斗和平板護 罩2之間介面59完全平行的平面内作雙向滑動,因而雷射 炼接頭55可按圖6所示之預定熔接路徑(ρΓ—Μ welding path) 60即沿圍板7的輪靡移動。 在圖5所示之較佳實施例中,在組裝時平板護罩2置 於下部,而平板後蓋4置於上部。雷射光束(laserbeam) Μ來自頂部。平板後蓋4和平板護罩2須由可以聚合的材 =製成以實現雷射熔接。在本實施例中,平板後蓋4對於 雷射光束61須是透光的,反之,平板護罩2則須是吸光的 ,由於雷射波長在可視光波長範圍之外,因而可根據製造 廠商的要求對上述兩部件2、4染色,使其對雷射光束61 分別具有充分的透光度和吸光度。 此外’由平板後蓋4和平板護罩2疊合(即通過邊框 38與上表面39耦合)形成的介面59須有足夠的面積使熔 接路徑(welding path)或熔化區(meit zone) 60不致蔓延 到介面59的邊緣。雷射熔接方法在美國專利案第 就中有更詳細的描述,在此將其作為參考文獻整體引用。 如上所述,之所以使用雷射熔接方法將平板後蓋4炫 接於平板護罩2,是因為需要使二者非常牢固地連接在_ 起’以防止在修刮時二者分離而劃傷使用者的面部(或正 20053嶋 在修刮的身體其他部位). 時_易將平柘饴罢, ,问時也為防止孩童玩弄刮鬍刀 才孝工易將千板後盖4從平板護罩 細m结在一 射炫接在—起的步驟。/㈣至〉、二個手柄塑膠零件雷 件須的中-個塑膠零 吸光的。 尤釆仵以通過,而另一零件則須是 的下:個f件可能是手柄的上部,而另—零件可能是手柄 下和上下兩部分被雷射炫接在—起構成整個手柄。 可將-裝飾嵌紙(如用作廣告)夾在上下部零件之 磷,通過透明的上部零件可看清其内容。 雖然本發明已以較佳實施例揭露如上,然其 限^本發明’任何熟習此技藝者,在不脫離本發明之 =範圍内’當可作些許之更動與潤飾,因此本發明之= 靶圍當視後附之申請專利範圍所界定者為準。 【圖式簡單說明】 ^圖1繪示為本發明一較佳實施例之含有三刀片的 鬍刀頭的示意圖。 、1 一圖2繪示為圖1所示刮鬍刀頭沿不同方向觀察 示意圖。 π守的 圖3繪示為圖1和圖2所示刮鬍刀頭的分解囷 20053i66^Qc (exploded perspective view)。其視角與圖 2 相同。 圖4纟會示為圖1、圖2和圖3所示之刮鬍刀頭分部件 組裝示意圖。 圖5纟會不為如述圖不之刮鬚刀頭的剖視圖*及雷射炼 接示意圖。 圖6緣示為前述圖示之電動到鬍刀頭一平板護罩的 頂視圖。 【主要元件符號說明】 • 1 :刮鬍刀頭 2:防護部件或平板護罩 3 :刀片組件 4 :平板後蓋 5:鎖定裝置 6 :基板 7 :圍板 8:内腔體積 9 :矩形開口 10 :防護擋條 11 :圍板平直部位 12 :基板6之内表面 13 :基板6之外表面或上表面 14 :潤滑條 15 :皮膚接觸元件 16 :緊固銷 19 200536696 17 :定位銷 18 :定位銷 19 :錐形表面 20 :錐形表面 21 :矩形開口 9之一端 22 :矩形開口 9之另一端 23 :刀片之端部 24 :刀片之端部 25 :第一刀片 26 :第二刀片 27 :第三刀片 28 :第一間隔片 29 :第二間隔片 30 ··緊固片 31 :刀刃 32 ··緊固孔 33 :刀片端部之矩形切口 34 :刀片端部之矩形切口 35 :通孔 36 :平板後蓋4之矩形蓋體 37 :矩形開口 38 :矩形開口 37之扁平邊框 39 :圍板7之上表面 40 :卡扣 20 20053i66p90c 41 :卡扣 42 :壓條 43 ··壓條 44 :弧形上表面 45 :弧形上表面 46 :圓柱面 47 :圓柱面 48 :弧形缝隙 49 :弧形縫隙 50 :平板後蓋4之凸輪裝置 51 :凸輪表面 52 :凸輪表面 53 :頂點 54 :緊固銷16之镦頭 55 :雷射熔接頭 56 :撓性雷射導向元件 57 :操作杆 58 :夾緊元件 59 :平板後蓋4與平板護罩2之間的介面 60 :預定熔接路徑或熔化區 61 :雷射光束 21
