Embodiment 1
[0077] This embodiment corresponds to the second and third principles mentioned above, that is, the situation where two reflective lenses are used to deflect light, see Figure 5 to Figure 10 , The laser marking machine of the present invention includes a cabinet 9, a reference board 7 arranged on the cabinet 9, a control unit 8 arranged on the cabinet 9, a lifting frame 6 vertically arranged on the reference board 7, a marking head 5, lifting The top of the frame 6 is provided with a rotating handle 61, the marking head 5 is arranged on the lifting frame 6, and the height of the marking head 5 can be adjusted by rotating the rotating handle 61. This is a manual adjustment method. The control unit 8 can also be used in the present invention. Automatically adjust the lifting frame 6, when the height difference of the marking object is large (beyond the laser marking focal length range), the position of the marking head 5 can be adjusted manually or automatically to make the marki...
Embodiment 2
[0086] See attached Picture 11 In this embodiment, the laser, the second visible light beam 321 emitted by the second visible light indicator 320, the reflection device (including the first mirror 332 driven and controlled by the first motor 331 and the second mirror 332 driven and controlled by the second motor 341 The mirror 342) is the same as the first embodiment. The difference is that the front housing of this embodiment is also provided with an adjusting device (a third mirror 352 driven and controlled by a third motor 351), and the first visible light indicator 310 emits The first visible light beam 311 is emitted. The first visible light beam 311 encounters the third reflector 352 during the transmission process. The first visible light beam 311 is reflected by the third reflector 352 and intersects the second visible light beam 321. The intersection point is For the optimal working point of laser marking, the additional adjustment device plays the same role as the sec...
Embodiment 3
[0088] See attached Picture 12 In this embodiment, the first principle is applied, that is, the second visible light beam 121 is reflected only once. The reflection device in this embodiment is different from the first embodiment, and the reflection device in this embodiment is driven by the first motor 131 The deflected first mirror 132.
[0089] The first visible light indicator 110 in this embodiment and the first visible light indicator 210 in the first embodiment can be installed on the front housing in the same manner. The first visible light indicator 110 in this embodiment emits the first visible light. The light beam 111 is a downward fixed light. The first reflecting mirror 132 controls the deflection of the second visible light beam 121 through the first motor 131 to achieve the effect of changing the height of the intersection; the structure of this embodiment is simple and the cost is low, and only needs to be used A reflective lens, but the requirements for install...
