Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laser processing, in particular to a laser processing real-time magnification observation device. Background Art
[0002] In the existing laser processing device, the laser emitted by the laser 1' passes through the galvanometer 2' and the field lens 3' and then irradiates on the workpiece for processing. However, the existing laser processing device only has a single laser 1' without an observation device, and it can only observe the processing situation of the workpiece with the naked eye or wearing protective glasses during processing. At the same time, the products processed by laser are relatively delicate. After processing, the workpiece needs to be taken off and placed under the two-dimensional for observing the processing situation. Taking it off and putting it on for observation seriously affects the efficiency on the one hand. On the other hand, when the workpiece is processed again, repeated clamping will affect the processing accuracy, resulting in problems in workpiece processing. Summary of the Utility Model
[0003] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a laser processing real-time magnification observation device, which can directly observe the workpiece during workpiece processing.
[0004] To achieve the above purpose and other related purposes, the present utility model provides a laser processing real-time magnification observation device, including a connection box connected to the laser and the galvanometer on both sides respectively, and an observation module communicated with the connection box. An incident light port connected to the laser, an outgoing light port connected to the galvanometer are arranged on the connection box, and an optical channel is arranged between the incident light port and the outgoing light port. An observation port is also opened on the surface of the connection box, and the observation port is communicated with the observation module.
[0005] Further, the observation module includes a magnifying objective lens connected to the observation port, a focusing objective lens connected to the magnifying objective lens, and a CCD camera connected to the focusing objective lens, and also includes a display electrically connected to the CCD camera.
[0006] Further, a beam combining mirror is arranged in the optical channel.
[0007] Further, a beam combining mirror bracket with a through hole is arranged in the optical channel, and the beam combining mirror is fixedly installed on the beam combining mirror bracket.
[0008] Further, the connection box is fixedly connected to the laser and the galvanometer respectively through screws.
[0009] Further, the magnifying objective lens is fixedly connected to the observation port through an objective lens clamp.
[0010] As described above, the laser processing real-time magnification observation device of the present utility model has the following beneficial effects:
[0011] The utility model solves the problem that the naked eye observation during processing stimulates the eyes and protects the eyes. At the same time, through the observation module, the processing condition of the workpiece can be directly observed, without the need for frequent picking and placing of the workpiece, which may lead to a reduction in the processing accuracy of the workpiece and finally result in processing errors and processing mistakes.

[0019] The utility model provides a laser processing real-time magnification observation device, which includes a connection box 8 connected to a laser 1 and a galvanometer 2 on both sides respectively, and an observation module communicated with the connection box 8. An incident light port connected to the laser 1 and an outgoing light port connected to the galvanometer 2 are arranged on the connection box 8, and an optical channel is arranged between the incident light port and the outgoing light port. When processing a workpiece, the laser emitted by the laser 1 enters the optical channel from the incident light port and then exits through the light outlet, enters the galvanometer 2, then enters the field lens 3 and finally reaches the surface of the workpiece 9, so as to process the workpiece 9.
[0020] Meanwhile, an observation port is also opened on the surface of the connection box 8, and the observation port is also communicated with the optical channel and is communicated with the observation module.
[0021] The observation module includes a magnifying objective lens 7 connected to the observation port, a focusing objective lens 6 connected to the magnifying objective lens 7, and a CCD camera 5 connected to the focusing objective lens 6. It also includes a display 4 electrically connected to the CCD camera 5. The display 4 can be set at any convenient observation position. In this embodiment, for the convenience of description, the display 4 is set on the upper surface of the laser 1.
[0022] Meanwhile, a beam combining mirror 12 is arranged in the optical channel. The beam combining mirror 12 can penetrate invisible light but cannot penetrate visible light. Therefore, the laser belongs to invisible light and can penetrate the beam combining mirror 12, while the light emitted by the workpiece 9 cannot pass through the beam combining mirror 12 and can only be reflected. And the position of the beam combining mirror 12 is set so that the reflection direction of the light transmitted by the workpiece faces the observation port.
[0023] Specifically, a beam combining mirror bracket 11 with a through hole is arranged in the optical channel, and the beam combining mirror 12 is fixedly installed on the beam combining mirror bracket 11.
[0024] Meanwhile, the connection box 8 is fixedly connected to the laser 1 and the galvanometer 2 respectively through screws.
[0025] The magnifying objective lens 7 is fixedly connected to the observation port through an objective lens clamp 10. The objective lens clamp 10 is fixedly arranged on the connection box 8 by means of bolts, and a through hole is arranged in the objective lens clamp 10 to conduct the reflected light.
[0026] During specific use, the laser 13 emitted by the laser 1 is transmitted to the galvanometer 2 through the optical channel, and then reaches the workpiece 9 through the field lens 3, so as to process the workpiece 9. Meanwhile, when the workpiece 9 is processed, the light emitted by the workpiece 9 is reflected in turn through the field lens 3, the galvanometer 2, the beam combining mirror 12, magnified by the magnifying objective lens 7, and then reaches the CCD camera 5 through the focusing objective lens 6, and the state of the workpiece 9 can be observed through the display 4.
[0027] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
