Description
本發明係關於鑽孔裝置。 The present invention relates to a drilling device.
藉由鑽頭在印刷基板等的工件進行鑽孔之鑽孔裝置為眾所皆知。例如,在專利文獻1記載有一種鑽孔裝置,其具備:機台;用來保持對載置於機台的印刷基板進行加工的工具並使其可旋轉升降之主軸;當加工印刷基板時,將印刷基板按壓於機台之按壓裝置。 A drilling device for drilling a workpiece such as a printed circuit board with a drill is well known. For example, Patent Document 1 describes a drilling device that includes: a machine table; a spindle for holding a tool for processing a printed circuit board placed on the machine table and making it rotatable and liftable; when processing the printed circuit board, The pressing device that presses the printed circuit board on the machine table.
一般,鑽孔裝置是在藉由接收構件將工件從鑽頭相反側朝鑽頭側按壓的狀態下,進行鑽孔加工。接收構件是設置成可更換。接收構件是當在更換後第一次使用時,與工件一同藉由鑽頭進行鑽孔。在第一次使用時鑽出的接收構件之孔,會在第二次以後的每次的鑽孔加工時被鑽頭插通。接收構件的孔會因反覆進行鑽孔加工而被鑽頭插通,因鑽頭的微小晃動,造成孔徑逐漸擴大。 Generally, a drilling device performs drilling in a state where the workpiece is pressed from the opposite side of the drill to the side of the drill by a receiving member. The receiving member is configured to be replaceable. When the receiving member is used for the first time after replacement, it is drilled by a drill together with the workpiece. The hole of the receiving member drilled during the first use will be penetrated by the drill every time after the second drilling. The hole of the receiving member will be penetrated by the drill bit due to repeated drilling, and the hole diameter will gradually expand due to the slight shaking of the drill bit.
[專利文獻1]日本專利第5138273公報 [Patent Document 1] Japanese Patent No. 5138273
但,在前述以往的鑽孔裝置,當接收構件的孔徑擴大的話,則工件進行鑽孔時,在接收構件的孔與鑽頭之間會產生間隙。 However, in the aforementioned conventional drilling device, when the hole diameter of the receiving member is enlarged, when the workpiece is drilled, a gap is generated between the hole of the receiving member and the drill bit.
在鑽頭貫通工件時,在接收構件的孔與鑽頭之間隙,構成工件的材料之一部分被擠出。因此,在形成於工件的孔之開口緣,會產生朝接收構件側突出之毛邊。 When the drill bit penetrates the workpiece, a part of the material constituting the workpiece is extruded in the gap between the hole of the receiving member and the drill bit. Therefore, at the opening edge of the hole formed in the workpiece, burrs protruding toward the receiving member side are generated.
又,為了抑制毛邊產生,亦考量在接收構件的孔擴大成預定的大小前更換接收構件。但,當頻繁地更換接收構件的話,則在每次進行更換時必須中斷鑽孔加工,造成製造效率降低。因此,在以往的鑽孔裝置,存在有既可抑制製造效率降低又可防止毛邊產生之課題。 In addition, in order to suppress the generation of burrs, it is also considered to replace the receiving member before the hole of the receiving member is enlarged to a predetermined size. However, if the receiving member is frequently replaced, the drilling process must be interrupted every time the replacement is performed, resulting in a decrease in manufacturing efficiency. Therefore, in the conventional drilling device, there is a problem that the generation of burrs can be prevented while suppressing the decrease in manufacturing efficiency.
因此,本發明的課題係在於提供製造效率佳、且能夠抑制毛邊產生之鑽孔裝置。 Therefore, the subject of the present invention is to provide a drilling device that has high manufacturing efficiency and can suppress the generation of burrs.
本發明的鑽孔裝置,其特徵為具備有:在工件進行鑽孔之鑽頭;將前述鑽頭可旋轉地保持的鑽頭保持部;接收構件,該接收構件是與前述鑽頭保持部相對向地 配置,當前述工件進行鑽孔時,將前述工件朝前述鑽頭保持部側按壓;及薄片狀中介構件,該中介構件是當前述工件進行鑽孔時,夾於前述接收構件與前述工件之間。 The drilling device of the present invention is characterized by comprising: a drill for drilling a workpiece; a drill holding portion for rotatably holding the drill; and a receiving member facing the drill holding portion When the workpiece is drilled, the workpiece is pressed toward the bit holding portion side; and a sheet-shaped intermediate member is sandwiched between the receiving member and the workpiece when the workpiece is drilled.
若依據本發明,當在工件進行鑽孔時,由於薄片狀的中介構件被夾於接收構件與工件之間,故,可藉由中介構件覆蓋工件之接收構件側的開口緣。藉此,當鑽頭貫通工件時,構成工件的材料與中介構件接觸,能夠防止從工件的接收件側之開口緣朝接收構件的孔與鑽頭之間的間隙被擠出。因此,當進行工件的鑽孔時,即使接收構件的孔徑擴大成預定的大小,亦不需要更換接收構件,能夠抑制在工件的接收構件側的開口緣產生毛邊。並且,由於中介構件為薄片狀,所以容易進行搬送,因此能將尚未使用的中介構件導入至接收構件與工件之間。因此,比起為了抑制毛邊產生而更換接收構件之情況,能夠更容易抑制毛邊產生。因此,能夠作成為製造效率佳、且能夠抑制毛邊產生之鑽孔裝置。 According to the present invention, when the workpiece is drilled, since the sheet-like intermediate member is sandwiched between the receiving member and the workpiece, the opening edge on the receiving member side of the workpiece can be covered by the intermediate member. Thereby, when the drill bit penetrates the workpiece, the material constituting the workpiece comes into contact with the intermediate member, which can prevent the workpiece from being pushed out from the opening edge of the receiving member side of the workpiece toward the gap between the hole of the receiving member and the drill bit. Therefore, when drilling the workpiece, even if the hole diameter of the receiving member is enlarged to a predetermined size, there is no need to replace the receiving member, and it is possible to suppress the occurrence of burrs on the opening edge of the workpiece on the receiving member side. In addition, since the intermediate member is in a sheet shape, it is easy to transport, and therefore, an unused intermediate member can be introduced between the receiving member and the workpiece. Therefore, the generation of burrs can be suppressed more easily than when the receiving member is replaced in order to suppress the generation of burrs. Therefore, it can be made into a drilling device that has high manufacturing efficiency and can suppress the generation of burrs.
在前述鑽孔裝置,前述中介構件形成為帶狀為佳。 In the aforementioned drilling device, it is preferable that the aforementioned intermediate member is formed in a belt shape.
若依據本發明,由於中介構件形成為帶狀,故,能夠使中介構件在接收構件與工件之間行進。藉由使中介構件行進,能夠讓中介構件之使用完畢的部分從接收構件與工件之間朝外側移動,並且能夠將中介構件之未使用的部分導入至接收構件與工件之間而予以夾住。因此,不會中斷 鑽孔加工,能夠將中介構件之未使用的部分導入至接收構件與工件之間,可抑制製造效率降低。 According to the present invention, since the intermediate member is formed in a belt shape, the intermediate member can be moved between the receiving member and the workpiece. By moving the intermediate member, the used part of the intermediate member can be moved outward from between the receiving member and the workpiece, and the unused part of the intermediate member can be introduced between the receiving member and the workpiece to be clamped. Therefore, it will not be interrupted The drilling process can introduce the unused part of the intermediate member between the receiving member and the workpiece, and can suppress the decrease in manufacturing efficiency.
在前述鑽孔裝置,還具備中介構件保持單元,該中介構件保持單元具有:第1捲筒,該第1捲筒是可捲繞前述中介構件,並與前述中介構件的一端部連接;和 第2捲筒,該第2捲筒是可捲繞前述中介構件,並與前述中介構件的另端部連接為佳。 The aforementioned drilling device further includes an intermediate member holding unit having: a first reel that can wind the intermediate member and is connected to one end of the intermediate member; and The second reel, the second reel is capable of winding the aforementioned intermediate member, and is preferably connected to the other end of the aforementioned intermediate member.
前述中介構件係對前述接收構件可自由裝卸地被設置為佳。 The aforementioned intermediate member is preferably provided so as to be freely attachable and detachable to the aforementioned receiving member.
若依據本發明,由於鑽孔裝置具備有對接收構件可自由裝卸的中介構件保持單元,故,在捲繞於第1捲筒與第2捲筒之中介構件被使用後,可將第1捲筒和第2捲筒與中介構件保持單元總括地更換。因此,能夠縮短中斷鑽孔加工的時間,可抑制製造效率降低。 According to the present invention, since the drilling device is equipped with an intermediate member holding unit that can be freely attached to and detached from the receiving member, the first reel can be used after the intermediate member is wound on the first reel and the second reel. The drum, the second reel and the intermediate member holding unit are replaced collectively. Therefore, the time for interrupting the drilling process can be shortened, and the reduction in manufacturing efficiency can be suppressed.
在前述鑽孔裝置,前述中介構件保持單元是與前述接收構件一體地移動為佳。 In the aforementioned drilling device, it is preferable that the aforementioned intermediate member holding unit moves integrally with the aforementioned receiving member.
若依據本發明,由於中介構件保持單元與接收構件一體地移動,故,能夠防止中介構件伴隨接收構件的移動,從第1捲筒及第2捲筒而鬆弛之情況產生。因此,例如能夠防止:在中介構件鬆弛的狀態下被夾於接收構件與工件之間,接收構件無法適當地按壓工件等的缺失產生。因此,能夠精密地進行工件之鑽孔加工。 According to the present invention, since the intermediate member holding unit and the receiving member move integrally, it is possible to prevent the intermediate member from being loosened from the first reel and the second reel following the movement of the receiving member. Therefore, for example, it is possible to prevent the occurrence of a defect in which the intermediate member is sandwiched between the receiving member and the workpiece in a slack state, and the receiving member cannot properly press the workpiece. Therefore, the workpiece can be drilled precisely.
在前述鑽孔裝置,還具備有:將前述第1捲 筒旋轉驅動,讓捲繞於前述第2捲筒的前述中介構件捲取到前述第1捲筒之驅動源;及對前述第2捲筒的旋轉賦予負荷之阻抗賦予手段。 The aforementioned drilling device is also equipped with: the aforementioned volume 1 The drum is rotationally driven to wind the intermediate member wound on the second drum to the drive source of the first drum; and impedance applying means for applying a load to the rotation of the second drum.
若依據本發明,由於藉由驅動源將第1捲筒旋轉驅動,讓捲繞於第2捲筒的中介構件捲取至第1捲筒,故,能夠自動且容易進行位於接收構件與工件之間的中介構件的行進。並且,鑽孔裝置由於具備有對第2捲筒的旋轉賦予負荷之阻抗賦予手段,故,當藉由第1捲筒的旋轉從第2捲筒拉出中介構件時,能夠防止:因慣性力使第2捲筒必要以上旋轉,造成從第2捲筒拉出的中介構件產生鬆弛之情況產生。因此,能夠可使製造效率提升,並且精密地進行工件之鑽孔加工。 According to the present invention, since the first reel is rotatably driven by the drive source, and the intermediate member wound on the second reel is wound to the first reel, it is possible to automatically and easily perform the process between the receiving member and the workpiece. The progress of intermediary components. In addition, since the drilling device is equipped with impedance applying means for applying load to the rotation of the second reel, when the intermediary member is pulled out from the second reel by the rotation of the first reel, it can prevent: Rotating the second reel more than necessary, causing slack in the intermediate member drawn from the second reel. Therefore, the manufacturing efficiency can be improved, and the workpiece can be drilled precisely.
在前述鑽孔裝置,前述第1捲筒及前述第2捲筒係隔著前述接收構件的前述鑽頭保持部側之面,配置於與前述鑽頭保持部相反側的位置為佳。 In the drilling device, it is preferable that the first reel and the second reel are on the side of the bit holding portion with the receiving member interposed therebetween, and are preferably arranged at a position opposite to the bit holding portion.
若依據本發明,因第1捲筒及第2捲筒係隔著接收構件的鑽頭保持部側之面,配置於與前述鑽頭保持部相反側的位置,所以,能夠不需考量與工件的接觸而加以設定第1捲筒及第2捲筒的配置位置。因此,例如可使第1捲筒及第2捲筒相互接近地配置,將中介構件保持單元小型化。 According to the present invention, since the first reel and the second reel are arranged on the opposite side of the drill holding portion via the surface of the receiving member on the bit holding portion side, it is possible to eliminate the need to consider contact with the workpiece Then, the arrangement positions of the first reel and the second reel are set. Therefore, for example, the first reel and the second reel can be arranged close to each other, and the intermediate member holding unit can be miniaturized.
若依據本發明,當在工件進行鑽孔時,由於 薄片狀的中介構件被夾於接收構件與工件之間,故,可藉由中介構件覆蓋工件之接收構件側的開口緣。藉此,當鑽頭貫通工件時,構成工件的材料與中介構件接觸,能夠防止從工件的接收件側之開口緣朝接收構件的孔與鑽頭之間的間隙被擠出。因此,當進行工件的鑽孔時,即使接收構件的孔徑擴大成預定的大小,亦不需要更換接收構件,能夠抑制在工件的接收構件側的開口緣產生毛邊。並且,由於中介構件為薄片狀,所以容易進行搬送,因此能將尚未使用的中介構件導入至接收構件與工件之間。因此,比起為了抑制毛邊產生而更換接收構件之情況,能夠更容易抑制毛邊產生。因此,能夠作成為製造效率佳、且能夠抑制毛邊產生之鑽孔裝置。 According to the present invention, when drilling a workpiece, because The sheet-shaped intermediate member is sandwiched between the receiving member and the workpiece, so the opening edge on the receiving member side of the workpiece can be covered by the intermediate member. Thereby, when the drill bit penetrates the workpiece, the material constituting the workpiece comes into contact with the intermediate member, which can prevent the workpiece from being pushed out from the opening edge of the receiving member side of the workpiece toward the gap between the hole of the receiving member and the drill bit. Therefore, when drilling the workpiece, even if the hole diameter of the receiving member is enlarged to a predetermined size, there is no need to replace the receiving member, and it is possible to suppress the occurrence of burrs on the opening edge of the workpiece on the receiving member side. In addition, since the intermediate member is in a sheet shape, it is easy to transport, and therefore, an unused intermediate member can be introduced between the receiving member and the workpiece. Therefore, the generation of burrs can be suppressed more easily than when the receiving member is replaced in order to suppress the generation of burrs. Therefore, it can be made into a drilling device that has high manufacturing efficiency and can suppress the generation of burrs.

As shown in FIG. 5, the sheet S drawn from the
以下,說明關於本實施形態的作用。 Hereinafter, the function of this embodiment will be explained.
首先,說明關於鑽孔裝置1的動作。再者,關於以下的說明之各構成零件,請參照圖2至圖6。又,在以下的說明,作為工件W,以印刷基板為例進行說明。 First, the operation of the drilling device 1 will be described. In addition, please refer to Figs. 2 to 6 for the components of the following description. In addition, in the following description, a printed circuit board is taken as an example of the work W.
當鑽孔裝置1進行工件W的鑽孔加工時,首先,藉由未圖示的工件移動機構及架台移動機構,使鑽頭D移動至對工件W之預定位置的上方。此時,亦可使用未圖示的X射線照相機,對工件W的電路之形成圖案進行攝像,精密地測定要進行鑽孔加工的位置。 When the drilling device 1 performs drilling of the workpiece W, first, the drill D is moved to above a predetermined position of the workpiece W by a workpiece moving mechanism and a gantry moving mechanism (not shown). At this time, an X-ray camera, not shown, may be used to image the formation pattern of the circuit of the workpiece W to precisely measure the position to be drilled.
其次,藉由未圖示的主軸移動機構使主軸部12朝工件W向下方移動,讓按壓構件13的下端部抵接至工件W的上面。又,藉由按壓單元移動機構使按壓單元20朝工件W向上方移動。此時,按壓單元20通過對鑽頭
襯套40形成在工件機台5且朝左右方向延伸之狹縫5a。按壓單元20隔著薄片S讓鑽頭襯套40的上面40a抵接於工件W的下面。如此,利用以按壓構件13及鑽頭襯套40在上下挾持工件W,能夠防止工件W的位置偏移及工件W的撓曲。
Next, the
其次,使主軸部12朝工件W進一步移動。此時,由於按壓構件13的下端部抵接於工件W,故,按壓構件13對主軸部12朝上方相對移動,且主軸部12進一步持續下降。藉此,安裝於主軸部12的下端之鑽頭D從按壓構件13的鑽頭孔13a朝下方突出,在工件W上進行鑽孔。再者,此時,使用未形成有鑽頭孔13a之新的按壓構件13之情況,藉由鑽頭D新形成鑽頭孔13a。
Next, the
貫通了工件W之鑽頭D在被夾於鑽頭襯套40與工件W之間的薄片S、及鑽頭襯套40上進行鑽孔。此時,藉由鑽孔加工所產生的工件W、薄片S及鑽頭襯套40的切削屑會被作成為負壓的鑽頭襯套支承部32所吸引,透過連通孔23a及圓管構件42送至外部。再者,在鑽頭襯套40為已經被使用之情況,鑽頭D插通於鑽頭襯套40上之既存的孔。形成在鑽頭襯套40上的孔,由於每次進行鑽孔加工則會被鑽頭D插通,故,鑽頭襯套40的孔會形成為因鑽頭D之微小的晃動而孔徑擴大之狀態。
The drill D penetrating the workpiece W drills holes in the sheet S sandwiched between the
若依據本實施形態的鑽孔裝置1,由於進行工件W的鑽孔時,薄片S被夾於鑽頭襯套40與工件W之間,故,可藉由薄片S覆蓋工件W的鑽頭襯套40側之開
口緣(以下稱為[下端開口緣])。藉此,當鑽頭D貫通工件W時,構成工件W的材料與薄片S接觸,能夠防止從工件W的下端開口緣朝鑽頭襯套40的孔與鑽頭D之間的間隙被擠出。因此,當進行工件W的鑽孔時,即使鑽頭襯套40的孔徑擴大成預定的大小,亦不需要更換鑽頭襯套40,能夠抑制在工件W的下端開口緣產生毛邊。並且,由於容易搬運薄片S,故,可容易將未使用的薄片S導入至鑽頭襯套40與工件W之間。因此,比起為了抑制毛邊產生而更換鑽頭襯套40之情況,能夠更容易抑制毛邊產生。因此,能夠作成為製造效率佳、且能夠抑制毛邊產生之鑽孔裝置1。
According to the drilling device 1 of this embodiment, since the sheet S is sandwiched between the
又,由於薄片S形成為帶狀,故,可使薄片S在鑽頭襯套40與工件W之間行進。藉由使薄片S行進,能夠讓薄片S之使用完畢的部分從鑽頭襯套40與工件W之間朝外側移動,並且能夠將薄片S之未使用的部分導入至鑽頭襯套40與工件W之間而予以夾住。因此,不會中斷鑽孔加工,能夠將薄片S之未使用的部分導入至鑽頭襯套40與工件W之間,可抑制製造效率降低。
In addition, since the sheet S is formed in a belt shape, the sheet S can be allowed to travel between the
又,鑽孔裝置1係具備對鑽頭襯套40可自由裝卸之薄片保持單元22。因此,在被捲繞於薄片收容捲架61及薄片回收捲架62(以下稱為[各捲架61、62])薄片S使用後,能夠將薄片保持單元22整個總括更換各捲架61、62。因此,能夠縮短中斷鑽孔加工的時間,可抑制製造效率降低。
In addition, the drilling device 1 is provided with a
又,由於薄片保持單元22是與鑽頭襯套40一體地移動,故,可防止薄片S伴隨鑽頭襯套40的移動,從各捲架61、62拉出而鬆弛的情況產生。因此,例如能夠防止:在薄片S鬆弛的狀態下被夾於鑽頭襯套40與工件W之間,鑽頭襯套40無法適當地按壓工件W等的缺失產生。因此,能夠精密地進行工件W之鑽孔加工。
In addition, since the
又,由於藉由驅動源30將薄片回收捲架62旋轉驅動,使薄片捲取捲架62捲取已被捲繞於薄片收容捲架61的薄片S,故,能夠自動且容易地進行位於鑽頭襯套40與工件W之間的薄片S的行進。並且,鑽孔裝置1係具備對薄片收容捲架61的旋轉賦予負荷的阻抗賦予手段66。因此,當藉由薄片回收捲架62的旋轉,將薄片S從薄片收容捲架61拉出時,能夠防止:因貫性力造成薄片收容捲架61需要以上旋轉,在自薄片收容捲架61拉出的薄片S產生鬆弛。因此,能夠可使製造效率提升,並且精密地進行工件W之鑽孔加工。
In addition, since the
又,因各捲架61、62是隔著鑽頭襯套40的上面40a而配置於主軸部12相反側,所以,可不需考量對工件的接觸,而能設定各捲架61、62之配置位置。因此,例如可使各捲架61、62相互接近地配置等,將薄片保持單元22予以小型化。
In addition, since the

例如,在前述實施形態,薄片S形成為帶狀,且在鑽頭襯套40與工件W之間行進,但,不限於此。例如,亦可使薄片形成為長條帶狀,從匣盒等適當地供給至鑽頭襯套40與工件W之間。
For example, in the foregoing embodiment, the sheet S is formed in a belt shape and travels between the
又,在前述實施形態,鑽孔裝置1係當進行工件W的鑽孔時,藉由按壓構件13按壓工件W的上面,但不限於此,鑽孔裝置亦可不具備按壓構件。
