Description of the Invention: [Technical Field] The present invention relates to a method for manufacturing a golf club head and a striking panel, and in particular to a The striking panel has a golf club head having a low modulus of elasticity and a method of manufacturing the striking panel. [Prior Art] Today's social movements are popular, and golf has long been one of the favorite sports of the public, and the number of people participating in golf has also increased rapidly. Among them, the golf club can be divided into many different types of clubs, such as wooden clubs, iron clubs and putters, depending on the terrain and use of the venue. For wood rods, the golf club head is usually made of metal or carbon fiber (carb 〇nfiber) to create a head body, and then the head body. A striking plate is attached to serve as a hitting ball. Because golf • club heads have certain specifications and restrictions in terms of size and weight, they can play the expected ball control and hitting effect when hitting. Therefore, in order to meet different usage requirements, in designing a golf club head, it is usually necessary to achieve an optimized design by changing the basic structure of the head body and the striking panel or a combination of the two. The homogeneous and uniform thickness of the panel is usually located in the center of the striking panel, and as the distance from the center, the counter-reaction coefficient of the striking panel will gradually decrease. In the case of 5 200821019^3 (^ 19914twf.doc/n, the coefficient of restitution (COR) of the striking panel, the area of the high reversal coefficient of the striking panel of the golf club head is as large as possible, so The hitting panel of the golf club head is designed to reduce the thickness of the panel to improve the impact resistance of the hitting ball. However, this method sacrifices the durability of the striking panel, and the striking panel is caused by the reduction of the thickness. The problem of easy breakage, how to improve the ability of hitting the ball easily and effectively without reducing the durability of the hitting panel, becomes a problem that is urgently needed to be dealt with in the design of the ball head. [The present invention] A golf club head is provided, which has a large area of high reversal coefficient of the striking panel.

包括一杯頭本體210與一打擊面板220。桿頭本體21〇具 有一開口 212,而打擊面板22〇配置於開口 212處，用以 與桿頭本體210構成（compose)高爾夫球桿頭2〇〇。在本 實施例中，桿頭本體210可為一殼體（sheU)，其可選用 12 200821019 013(1) 19914twf.doc/n 一般之金屬材質（如不銹鋼等金屬材質），且以脫蠟鑄造 (lost-wax casting)方式一體成型地製成。 當然，在本發明其他的實施例中，桿頭本體21〇亦可 以是由金屬與高分子塑化材料或高強度纖維材料（例如碳 纖維）等複合材質所構成，其製作方式例如是預先以射出 成型（injection m〇lding)或熱壓成型（thermalc〇mpressi〇n molding)方式獨立製作一上蓋（cr〇wn)(未繪示），再 將此上蓋嵌合於其他部分的金屬殼體上。此外，亦有其他 作法疋直接在金屬殼體之鏤空處貼覆碳纖維預浸布，再搭 配模具與氣袋加熱成型，以形成桿頭本體21〇。 請參考圖2與圖3，其中圖2繪示圖1之打擊面板的 正視示意圖，而圖3繪示圖1之打擊面板的側視示意圖。 打擊面板220具有一打擊面222，打擊面板220包括一面 板本體224與至少一低彈性模數部位226 (圖1與圖2中 分別示意地繪示兩個）。面板本體224配置於開口 212處， 且面板本體224具有至少一曝露於外的凹穴224a (圖1與 圖2中分別示意地繪示兩個）與一曝露於外的第一表面 224b，其中各個凹穴224a的深度D小於面板本體224的 厚度τ。在本實施例中，這些凹穴224a通常位於面板本體 224的中心區域224c之外，且這些凹穴224可以銑削的方 式成型。 此外’這些低彈性模數部位226分別填滿這些凹穴 224a ,所以這些低彈性模數部位226的數量是與這些凹穴 224a的數量相同。各個低彈性模數部位226具有一曝露於 13 200821019轉) 19914twf.doc/n 外的第二表面226a，其中面板本體224的第一表面224b 與這些低彈性模數部位226的這些第二表面226a構成 (compose)打擊面板220的打擊面222，且各個低彈性模 數部位226的彈性模數小於面板本體224的彈性模數。 在此必須說明的是，所謂的彈性模數即是揚氏模數 (Young’s modulus)，其公制單位為帕（Pascal，簡寫為 Pa)。材料（通常為單原子金屬或合金）的彈性模數與反 發係數呈現反比關係，亦即上述材料的彈性模數越低，則 其反發係數越高。因此，本實施例之打擊面板220除了面 板本體224之中心區域224c的反發係數相對較高之外，打 擊面板220所具有的這些低彈性模數部位226的反發係數 也相對較高，因此整體而言打擊面板220的高反發係數區 域較大。 在本實施例中，面板本體224的彈性模數可大於等於 lOOGPa (即ΙΟΟχΙΟ9帕），且各個低彈性模數部位226之 彈性模數與面板本體224之彈性模數的差值的絕對值可大 於等於lOGPa。此外，在本實施例中，面板本體224之第 一表面224b在這些凹穴224a上方的延伸面可與這些低彈 性模數部位226的這些第二表面226a重合。換言之，第一 表面224b與這些第二表面224a可平滑地（sm〇〇thly)彼 此接合在一起。另外，在本實施例中，面板本體224的材 質與低彈性模數部位226的材質可不同，其中面板本體224 的材質可為鈦合金，而在另一實施例中，這些低彈性模數 部位226的材質可為沒型鈦合金，例如為鈦_15釩-3鋁-3 200821019_ 19914twf.doc/n 鉻-3錫，其組成成分的重量百分比為76%鈦、15%釩、3% 鋁、3%鉻與3%錫的鈦合金。再者，各個凹穴224a的深度 D小於等於2公釐。 在本實施例中，這些凹穴224a的外型可為規則形狀， 其例如為橢圓形。然而，這些凹穴224a的外型可依照設計 者的需求而有所改變，例如可為圓形或多邊形，甚至可為 不規則形狀。據此，本實施例是用以舉例而非限定本發明。 請再參考圖1，值得一提的是，在本實施例中，桿頭 本體210與打擊面板220可藉由嵌合與（或）焊接等方式 相接合。進言之，在放置打擊面板220之前，可預先塗覆 焊料於桿頭本體210與打擊面板220之接合面上。之後， 將打擊面板220配置於桿頭本體210的開口 212處，再進 行焊接，以使焊料熔融後冷卻形成連接桿頭本體21〇與打 擊面板220之焊結層（未繪示）。此外，在另一實施例中， 亦可先將打擊面板220配置於桿頭本體210的開口 212 處’再將焊料塗覆於桿頭本體210與打擊面板220之接合 處的接縫上，待焊料熔融滲入接合面後，再冷卻凝固形成 焊結層（未纟會示）。 在說明過高爾夫球桿頭200之桿頭本體210的製造方 式，以及桿頭本體21〇與打擊面板220的組裝方式之後， 以下將針對打擊面板22〇的製造方法作一詳細說明。圖4A 至圖4D繪示圖1之打擊面板的製造流程示意圖，為了以 下方便說明，圖4A至圖4D作局部剖視。本實施例之打擊 面板220的製造方法包括以下步驟。首先，請參考圖4a， 15 200821019 013(1) 19914twf.doc/n f供一面板本體224，面板本體224具有多個凹穴224a與 第表面224b，其中各個凹穴224a的深度D小於面板 本體224的厚度τ。 ，著，請參考圖4β，將一低彈性模數材料M填入這 些凹穴224a。本實施例中，各個凹穴224a内的低彈性模 數材料M的體積可近似等於各個凹穴224a的容積。、 。之後，凊參考圖4C，加熱熔融這些凹穴224a内的低 彈性模數材料Μ。本實施例中，加熱熔融這些凹穴224a 内之低彈性模數材料M的方式包括照射高能雷射光束或 電子束於低彈性模數材料Μ。 然後’晴參考圖4D，退火（anneal)這些凹穴224a 内的低彈性模數材料M，以形成多個低彈性模數部位 226 ’其中各個低彈性模數部位220具有一曝露於外的第二 表面226a，而面板本體224的第一表面224b與這些低彈 性模數部位226的這些第二表面226a構成一打擊面222， 且各個低彈性模數部位226的彈性模數小於面板本體224 的彈性模數。經由上述圖4A至圖4D的步驟之後，一種打 擊面板220基本上即可完成。 在另一實施例中，在上述形成這些低彈性模數部位 226的步驟之後，打擊面板220的製造方法更包括對於打 擊面222進行表面處理（例如研磨或拋光），使得面板本 體224之第一表面224b在這些凹穴224a上方的延伸面是 與這些低彈性模數部位226的這些第二表面226a重合。換 έ之’第一表面224b與這些第二表面224a可平滑地彼此 16 200821019 013(1) 19914twf.doc/n 接合在一起。 第二實施例 圖5繪示本發明第二實施例之一種打擊面板的側視示 意圖。第二實施例之打擊面板320與第一實施例之打擊面 板220的主要不同之處在於，第二實施例之打擊面板32〇 不具有凹穴224a，而這些低彈性模數部位326可藉由滲入 的方式配置於面板本體324内，且這些低彈性模數部位326 的深度D’可小於等於2公釐。 圖6A至圖6D繪示圖5之打擊面板的製造流程示意 圖。本實施例之打擊面板320的製造方法包括包括下列步 驟。首先，請參考圖6A，提供一面板本體324，其具有一 第一表面324b。接著，請參考圖6B，將一低彈性模數材 料Μ塗覆於至少部分第一表面32415上。 之後，請參考圖6C，例如以照射高能雷射光束或電 子束於低彈性模數材料Μ的方式加熱熔融低彈性模數材 料Μ ’使得至少部分低彈性模數材料μ滲入面板本體324 内。然後，請參考圖6D，退火低彈性模數材料μ，以形 成至少一低彈性模數部位326，其中低彈性模數部位326 具有一曝露於外的第二表面326a，而第一表面324b與第 二表面326a構成一打擊面322，且低彈性模數部位326的 彈性模數小於面板本體324的彈性模數。經由上述圖6A 至圖6D的步驟之後，一種打擊面板32〇基本上即可完成。 在另一貫施例中，在上述形成這些低彈性模數部位 326的步驟之後，打擊面板32G的製造方法更包括對於打 17 200821019卿) 19914twf.doc/n 擊面322進行表面處理（例如研磨或拋光），使得面板本 體324之第一表面324b在這些低彈性模數部位326上方的 延伸面是與這些低彈性模數部位326的這些第二表面326a 重合。換言之，第一表面324b與這些第二表面326a可平 滑地彼此接合在一起。 综上所述，本發明之高爾夫球桿頭與打擊面板的製造 方法至少具有以下的優點： 一、 由於本發明之打擊面板具有這些低彈性模數部 位，且這些低彈性模數部位的反發係數相對較高，因此整 體而言本發明之打擊面板的高反發係數區域較大。 二、 由於本發明之打擊面板的製造方法可在不犧牲面 板本體之耐久性的前提下，以加熱熔融再退火低彈性模數 材料的方式於面板本體内形成低彈性模數部位，因此可擴 大打擊面板的高反發係數區域。 、 —雖然本發明已以較佳實施例揭露如上，然其並非用以 限定本發明，任何所屬技術領域中具有通常知識者，在不 ，脫離本發明之精神和範圍内，當可作些許之更動與潤飾， 因此本發明之保護範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繪不本發明第一實施例之一種高爾夫球桿頭的立 體分解示意圖。 圖2繪示圖1之打擊面板的正視示意圖。 18
