Embodiment 1

[0022] Such as figure 1 As shown, the laser ablation telecentric stabilization mechanism provided by the embodiment of the present invention includes a first parallelogram motion unit 1, a second parallelogram motion unit 2, a third parallelogram motion unit 3, a fourth parallelogram motion unit 4 and Central pole 5; wherein, the first parallelogram movement unit 1 and the second parallelogram movement unit 2 are in the first plane, and the third parallelogram movement unit 3 and the fourth parallelogram movement unit 4 are in the second plane. Before the movement, the first plane is perpendicular to the second plane, and the intersection of the downward extension line of the central rod 5 and the line connecting the bases of the first parallelogram movement unit 1 and the second parallelogram movement unit 2 is point O.

[0023] Further, such as figure 2 As shown, the first parallelogram motion unit 1 includes: a first spherical joint 11, a second spherical joint 12, a thir...

Embodiment 2

[0029] The difference from Embodiment 1 is that one end of the first connecting rod 19 in the laser ablation telecentric stabilization mechanism in this embodiment is fixedly connected to the frame, and the second connecting rod in the second parallelogram motion unit 2 The bar is also fixedly connected with the frame, the third one link in the third parallelogram motion unit 3 is also fixedly connected with the frame, and the fourth one link in the fourth parallelogram motion unit 4 is also fixedly connected with the frame, At this time, each motor can be installed on its corresponding horizontal connecting rod. The axis of the motor is parallel to the horizontal connecting rod, and it is connected with the connecting rod to be controlled by a ball joint coupling. For example: the first motor is installed On the first connecting rod 19, its axis is parallel to the first connecting rod, and its axis is respectively connected with the fifth connecting rod 113 and the second conn...

Embodiment 3

[0031] The difference from Embodiment 1 is that the laser ablation telecentric stabilization mechanism in this embodiment only has the first parallelogram motion unit 1, the second parallelogram motion unit 2 and the central rod 5, and other structures are similar, and no longer repeat.

[0032] In this embodiment, the two parallelogram motion units are connected through the rotating pair on the central rod 5 and are in the same plane. The connection between the two parallelogram motion units can realize the rotation of the final laser with the O point as the center of the sphere, that is The telecentricity is stable, and the introduction of two motion units can reduce the defect of high end inertia of one motion unit.

[0033] It can be seen that the structure of the laser ablation telecentric stabilization mechanism provided by the present invention is relatively simple, suitable for the field of laser ablation, and can achieve telecentric stabilization. The number of units ...

Abstract

The invention discloses a laser ablation telecentric stabilization mechanism and belongs to the technical field of laser ablation equipment. The laser ablation telecentric stabilization mechanism comprises two parallelogram motion units of the same structure, a center rod and a driving mechanism. The two parallelogram motion units are connected with the center rod through rotation pairs correspondingly and connected with other connecting rods through spherical hinges. The other connecting rods are connected with rotation pairs. The driving mechanism drives the connecting rods to rotate and swing left and right around the connecting rods at the bottom. The two connecting rods on the bottom sides of the two parallelogram motion units are kept fixed. A laser device is mounted on the center rod, and then telecentric stabilization of the point O of the laser device can be achieved. The laser ablation telecentric stabilization mechanism is relatively simple in structure. The number of the motion units can be set according to motion tasks. Telecentric stabilization can be achieved without a sensor and a servo mechanism. The tail-end inertia can be reduced through the two motion units.

Description

technical field [0001] The invention relates to the technical field of laser ablation equipment, in particular to a laser ablation telecentric stabilization mechanism. Background technique [0002] Laser ablation technology is an interdisciplinary science that integrates solid-state physics, microbeam technology, and laser chemistry. It ablates the surface of materials through femtosecond-nanosecond pulsed lasers, and has been widely used in micromachining and surgery. , laser spot welding, X-ray laser, biomolecular mass spectrometry, and art restoration / cleaning. According to the environment of the ablated material, it can be divided into gas phase ablation and liquid phase ablation. Liquid phase ablation technology and gas phase ablation technology are similar in the interaction mechanism between laser and matter, the only difference is the reaction environment in which the laser interacts with materials. In gas phase ablation technology, laser ablation technology is mai...
