鑽頭排屑改良結構 Drill chip removal improved structure

本創作係有關於一種鑽頭排屑改良結構，尤指一種藉由切削刀刃至少一側凹設有沿著該排屑槽向下螺旋延伸至底部的一V型溝槽以達到輔助鑽頭更佳有效排屑，以避免鑽針斷裂，進而使鑽孔加工品之良率及品質整體提升之功效。 The present invention relates to an improved structure for chip removal of a drill bit, especially a V-shaped groove that is concave on at least one side of the cutting edge and extends spirally downward along the chip removal groove to the bottom, so as to achieve a better and more effective auxiliary drill. Chip removal to avoid drill needle breakage, thereby improving the overall yield and quality of drilled products.

按，現今電子產品的使用量提升，人們對於電子產品的依賴性也愈來愈重，而隨著生活形態的改變，這些日常隨身攜帶的電子產品也逐漸有小型化的趨勢，而為了因應現代科技的進步，電子產品製作所需的電子零件也是往小型化的方向前進，其中最為影響電子產品的莫過於印刷電路板(PCB)的量產，而印刷電路板在於體積小型化的製造過程中，一般會有應用鑽針在電路板上鑽孔的步驟，其目的是為了連接電路板內層的線路供應電子元件之接腳的插接，並形成電性連接。 According to the increasing use of electronic products nowadays, people are more and more reliant on electronic products, and with the change of lifestyle, these electronic products that are carried with you every day are also gradually miniaturized. With the advancement of science and technology, the electronic parts required for the production of electronic products are also moving in the direction of miniaturization. Among them, the most influential electronic product is the mass production of printed circuit boards (PCBs), and printed circuit boards are in the process of miniaturization. Generally, there will be a step of drilling holes on the circuit board by using a drill, the purpose of which is to connect the lines on the inner layer of the circuit board to supply the pins of the electronic components, and form electrical connections.

然而，由於印刷電路板係為各式材料(如玻璃纖維及銅箔等)經過壓合形成的覆合基板所製成，這些材料會經過高溫會熔化而形成膠渣、殘膠，該些膠渣、殘膠不僅會使鑽針容易因切削阻力過大導致鑽孔之品質與良率降低，甚至於在鑽孔的過程中，因為過多的膠渣、殘渣導致鑽針阻塞，進一步的影響鑽孔過程，鑽針可能因此而變遲緩，乃至於在鑽孔過程中產生斷裂的狀況，縱使鑽針不斷裂，其受影響的鑽孔也無法保持在良好的狀態，可能會在多處留下不平整的鑽孔，進而影響整體的印刷電路板的印刷過程，並且浪費了電路版印製的材料和金錢，以上即為有待從事於此行業者所亟欲研究改善之關鍵所在。 However, since the printed circuit board is made of a laminated substrate formed by laminating various materials (such as glass fiber and copper foil, etc.), these materials will be melted at high temperature to form scum and residual glue. Slag and residual glue will not only make the drill easy to reduce the quality and yield of drilling due to excessive cutting resistance, but even in the process of drilling, due to excessive glue and residue, the drill will be blocked, which will further affect the drilling. process, the drill may become sluggish, even after drilling Even if the drill needle does not break, the affected drill holes cannot be kept in good condition, and uneven drill holes may be left in many places, thereby affecting the printing process of the overall printed circuit board. , and wastes the materials and money of circuit board printing.

The improved structure for chip removal of a drill bit mainly includes a drill bit 1, the drill bit 1 has a shank portion 11, and an edge portion 12 extends from one side of the shank portion 11, and at least one cutting edge 13 is formed at the top of the edge portion 12. 13 extends inwardly with a helical chip flute 14, and at least one side of the cutting edge 13 is concavely provided with a helical downward spiral along the chip flute 14 to the junction of the drill bit 1 and the shank 11. A V-shaped groove 15, the width of the V-shaped groove 15 is 0.01~0.08mm, the depth of the V-shaped groove 15 is 0.01~0.1mm, and the V-shaped groove 15 is cut from the The depth of one side of the cutting edge 13 is 0.1 mm, which tapers downward to 0.01 mm and then extends to the space between the drill bit 1 and the shank 11 . At the junction, in order to assist the chip removal groove 14 for more effective chip removal, the cutting edge 13 has a drill tip 131 at the top, and a cutting edge portion 132 extends downward on both sides with the drill tip 131 as the center.

本創作之鑽頭排屑改良結構於實際鑽孔作業時，係將該切削刀刃13的鑽尖131先接觸於一預設電路板的表面上，在藉由轉動鑽頭1令該切削刀刃13之該些刃面部132鑽進該預設電路板中，令該預設電路板上形成具有上下穿透狀的一孔洞，並於鑽洞過程中，該些排屑槽14中個別凹設的該V型溝槽15能夠輔助該排屑槽14進行排屑作業，由於該V型溝槽15之頂部深度較深，能在鑽入作業時更迅速的鑽入該預設電路板中，且該V型溝槽15向下漸縮的設計能夠更加方便殘屑的排出，令該鑽頭1於排屑過程中能夠更加順利的排出殘屑，令該鑽頭1於鑽孔過程中不會被多餘的殘屑阻塞，進而避免鑽針斷裂的可能信，並提升鑽洞的品質，進而達到鑽孔加工品之良率及品質整體提升。 In the actual drilling operation, the drill tip 131 of the cutting edge 13 first contacts the surface of a predetermined circuit board, and the drill bit 1 is rotated to make the cutting edge 13 . The cutting edge surfaces 132 are drilled into the predetermined circuit board, so that a hole having an up-down penetration shape is formed on the predetermined circuit board. During the drilling process, the V grooves 14 are individually recessed. The V-shaped groove 15 can assist the chip removal groove 14 to carry out the chip removal operation. Since the top of the V-shaped groove 15 has a deep depth, it can be drilled into the preset circuit board more quickly during the drilling operation, and the V-shaped groove 15 can be drilled more quickly. The downward tapered design of the groove 15 can facilitate the discharge of debris, so that the drill bit 1 can discharge the debris more smoothly during the process of chip removal, so that the drill bit 1 will not be excessively debris during the drilling process. Chips are blocked, thereby avoiding the possibility of breakage of the drill needle, and improving the quality of the drilled hole, thereby achieving the overall improvement of the yield and quality of the drilled products.
