Description

Technical Field

[0001] The invention relates to the technical field of two-dimensional galvanometer systems, and in particular to three red light-assisted two-dimensional galvanometer systems. Background Art

[0002] As is known to all, the three-red-light-assisted two-dimensional galvanometer system is a two-dimensional galvanometer equipped with three red lights, which can assist the two-dimensional galvanometer to perform laser beam focal length adjustment operations.

[0003] During the laser output process, the laser uses a two-dimensional scanning galvanometer to adjust the specific direction and position of the laser. A field lens is provided under the scanning head of the galvanometer. After the laser beam output by the laser passes through the galvanometer and the field lens, the laser beam can be focused into a focus for laser engraving text, patterns and other graphics. The general two-dimensional scanning galvanometer does not have the function of assisting in adjusting the focal length during the laser output process, so it brings certain difficulties to the adjustment of the focal length of the laser during the laser engraving process. It is necessary to manually adjust the position of the galvanometer for many times to find the position of the best focal length. At present, the common methods for adjusting the focal length are: 1. Adjust the position of the galvanometer for many times, and engrave a pattern while changing the position of the galvanometer. Determine whether the focal length is appropriate by observing the laser intensity of the laser engraving and the effect of the engraved pattern with the naked eye; 2. Engrave patterns at different positions of the same product or on different products. After finding a relatively suitable focal length through the above method for the first time, measure the distance h from the surface of the object to the field lens. Then, when moving the product or replacing the product for the second engraving, adjust the position of the galvanometer. When the distance from the field lens to the surface of the object is h, it is determined to be the same as the focal length of the previous engraving.

[0004] Although the above-mentioned prior art solutions can realize the auxiliary adjustment of the focal length of the laser beam output by the two-dimensional galvanometer, the method of determining the focal length in method 1 requires repeated adjustment of the position of the galvanometer and there is no fixed reference object, which may cause inconsistent pattern effects of the graphics engraved twice or more at different positions on the same product. At the same time, the operation is relatively cumbersome. Method 2 requires the focal length to be determined by measurement. First of all, this measurement itself has certain errors. Secondly, the surface of some objects to be laser engraved may be very small, which makes the measurement difficult to implement. Summary of the invention

[0041] The galvanometer module 1, field lens module 2, servo motor 14 and pressure resistor sensor 17 in this embodiment are all conventional devices purchased on the market and known to those skilled in the art. In the present invention, we only use them without improving their structures and functions. For those skilled in the art, their setting methods, installation methods and electrical connection methods only need to be debugged and operated according to the requirements of their instruction manuals, and will not be described in detail here.

[0042] To sum up, the working principle of the three red light-assisted two-dimensional galvanometer system is as follows: when in use, first select a laser to match the galvanometer module 1, and install an optical fiber and a signal line between the laser and the galvanometer module 1. The optical fiber forms the conduction of the laser beam, and the signal line forms the transmission of the control signal between the galvanometer module 1 and the laser. In the focusing process before the two-dimensional galvanometer operates relative to the workpiece surface, the first red light lamp group 4, the second red light lamp group 5 and the third red light lamp group 6 all emit red light. The first red light lamp group 4 emits red light to the beam combining lens 9. Under the action of the beam combining lens 9, the red light is reflected 90 degrees to the XY lens in the galvanometer module 1 and then reflected onto the workpiece surface (the debugging fixed seat 7 is synchronized with the laser), the second red light lamp group 5 and the third red light lamp group 6 also emit red light. The light paths of the three red lights are overlapped and projected onto the workpiece surface. The overlap of the three red light paths can be visually observed with the eyes to form an auxiliary adjustment operation of the laser beam focal length. The specific adjustment principle is shown in the attached figure. Fig. 9As shown, H is the relative distance between the overlapping point of the three red light paths and the incident laser, that is, the distance from the incident laser to the workpiece surface when the incident laser is in the state of focal length to the workpiece surface, so as to ensure that the laser beam is generated from the laser and is processed sequentially by the galvanometer module 1 and the field lens module 2 and finally forms a focus on the workpiece surface, so as to prepare for the workpiece surface processing. The distance between the field lens module 2 and the workpiece surface in the state of focus adjustment completed in the previous step is set as the focusing standard distance, the power supply of the spiral wire 35 is turned on, and the strength of the magnetic field generated by the electromagnet is controlled by controlling the current in the spiral wire 35, thereby achieving the first iron plate 26, the first vertical spring 27, the second iron plate 28, the second vertical spring 29, the third iron plate 30, The overall length control formed by the third vertical spring 31, the fourth iron plate 32 and the fourth vertical spring 33 makes the ball head block 46 contact with the workpiece surface without forming a large interaction force on the workpiece surface, that is, when the ball head block 46 contacts the workpiece surface and forms a relative movement, it will not cause pressure loss on the workpiece surface. Maintaining this state, during the movement of the field lens module 2 relative to the workpiece surface, the ball head block 46 will also form a synchronous movement relative to the workpiece surface. When the ball head block 46 moves relatively smoothly relative to the workpiece surface, the connecting ball 21 maintains a relatively upright state in the ball cavity hole 20 under the action of the conical tension spring 22. When the workpiece surface changes its pushing state relative to the ball head block 46 due to shape changes, it will pass The relative movement of the connecting ball 21 in the ball cavity 20 is formed through the sequential conduction of the first iron plate 26, the first vertical spring 27, the second iron plate 28, the second vertical spring 29, the third iron plate 30, the third vertical spring 31, the fourth iron plate 32, the fourth vertical spring 33 and the hanging frame 25. Due to the transmission effect of the conical tension spring 22 and the force transmission frame 23, it is finally manifested as a change in the pressure value of the pressure resistor sensor 17, and the servo motor 14 is powered on and operated. Through the meshing transmission of the driving spur gear 18 and the driven spur gear ring 19, the rotation drive of the outer cam 15 can be realized. The rotation of the outer cam 15 drives the detection contact 16 to form a multi-point detection of an annular track on the surface of the workpiece, and finally the corresponding posture and distance of the field lens module 2 relative to the surface of the workpiece are achieved. The detection and verification provides accuracy and convenience for the operation of the field lens module 2. Taking the workpiece surface as a plane as an example, when the detection contact 16 completes the detection of multiple points on a circular trajectory, if the detection value deviation of the pressure resistor sensor 17 at multiple detection points is not large, it means that the posture of the field lens module 2 relative to the workpiece surface is the correct posture in the vertical direction. When the detection contact 16 completes the detection of multiple points on a circular trajectory, if the detection value deviation of the pressure resistor sensor 17 at multiple detection points is large, it means that the posture of the field lens module 2 relative to the workpiece surface is tilted and needs to be adjusted to ensure that the laser beam has a good focusing state relative to the workpiece surface during the movement relative to the workpiece surface.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
