Embodiment Construction

[0017] Such as figure 1 As shown in the laser rotary cutting drilling device, the laser is a Q-switched pulse laser with a pulse width less than 20 ns, the output end of the laser is provided with a beam expander 1, and the output end of the beam expander 1 is arranged with a 45-degree total reflection mirror 2, 45 The output end of the total reflection mirror 2 is arranged with an optical rotation system 3, the optical rotation system 3 includes a first wedge prism 31, a second wedge prism 32, a third wedge prism 33 and a fourth wedge prism 34, the first wedge prism 31 and the second wedge prism The wedge prism 32 is a wedge prism with the same wedge angle. The first wedge prism 31 or the second wedge prism 32 is connected with the up and down linear motion mechanism and can move up and down along the axis. The third wedge prism 33 and the fourth wedge prism 34 have the same wedge angle. The wedge prisms, the third wedge prism 33 or the fourth wedge prism 34 are connected wit...

Abstract

The invention relates to a laser rotary-cut drilling device. The output end of a laser is provided with a beam expander; the output end of the beam expander is provided with a 45-degree total reflection mirror; the output end of the 45-degree total reflection mirror is provided with an optical rotation system; the optical rotation system comprises a first wedge prisma, a second wedge prisma, a third wedge prisma and a fourth wedge prisma; the first wedge prisma and the second wedge prisma have the same wedge angles; the first wedge prisma or the second wedge prisma is connected with a vertical straight-line motion mechanism; the third wedge prisma and the fourth wedge prisma have the same wedge angles; the third wedge prisma or the fourth wedge prisma is connected with a rotation mechanism; the output end of the optical rotation system is provided with a focus lens; and the focus lens is just opposite to a processing platform. The device is used for performing laser rotary-cut drilling on a workpiece, and can process straight holes, variable taper holes and irregular taper holes, so a laser drilling effect of variable sizes, controllable taper and smooth edges is achieved.

Description

technical field [0001] The invention relates to a drilling processing equipment, in particular to a laser rotary cutting drilling device. Background technique [0002] The biggest disadvantage of traditional mechanical drilling is that it cannot drill micro-holes (less than 200um), and the drill bits are consumables, resulting in high drilling costs. [0003] Due to its advantages over traditional drilling techniques, laser drilling has been used in many fields. Its advantages include non-contact processing, low heat input into the material, a wide range of materials to be drilled, accuracy and consistency, the ability to drill μm-sized holes, small holes with large aspect ratios and drilling at different angles hole. Commonly used drilling techniques include fixed-point percussion drilling and rotary cutting drilling. Among them, percussion drilling refers to continuous processing with a pulsed laser beam at one position until the hole is opened. High-speed flight drill...
