[0034] The following is in conjunction with the appendix Figures 2-3 This application will be described in further detail.

[0035] This application discloses a laser marking device with line length marking function. (Refer to...) Figure 2 The laser marking device with line length marking function includes a mounting base 1, a laser marking instrument 2 hinged to the top of the mounting base 1, the front of the laser marking instrument 2 facing the positioning wall, the laser marking instrument 2 emitting a laser spot, the operator controlling the laser spot to move to the positioning wall to measure the straightness of the object to be measured, and laser rangefinders 3 are provided on both sides of the laser marking instrument 2, the laser rangefinders 3 are activated to measure the line length of the object to be measured.

[0036] Reference Figure 2 and Figure 3 The mounting base 1 includes a support leg 11, which is placed on a standard horizontal surface. A telescopic support rod 13 is fixed to the top of the support leg 11, and a mounting base 12 is fixed to the top of the telescopic support rod 13. The telescopic support rod 13 is used to adjust the height difference between the support leg 11 and the mounting base 12, thereby initially adjusting the position of the laser marking instrument 2 on the mounting base 12.

[0037] Reference Figure 2 and Figure 3 The mounting base 12 includes a pitch adjustment assembly 121. Since the horizontal position of the pitch adjustment assembly 121 does not need to be adjusted, the pitch adjustment assembly 121 is fixed to the mounting base 12 by welding.

[0038] Reference Figure 2 and Figure 3The pitch adjustment assembly 121 includes a snap-fit ​​base 1211 for pitch adjustment of the laser marking instrument unit 2. The snap-fit ​​base 1211 is U-shaped, and the mounting groove 1212 in the middle of the snap-fit ​​base 1211 can be used for mounting the laser marking instrument unit 2. The laser marking instrument unit 2 includes a laser marking instrument 21. Positioning shafts 22 are fixed to both sides of the laser marking instrument 21. The positioning shafts 22 are rotatably connected to the snap-fit ​​base 1211. After manual adjustment, the laser marking instrument 21 can be adjusted from -30° to +60° on the pitch plane. Specifically, the pitch angle of the laser marking instrument 21 in the figure is 0°.

[0039] Reference Figure 2 and Figure 3 The mounting base 12 includes a pitch adjustment assembly 121. The mounting base 12 has a slide groove 123. The guide strip 1213 at the bottom of the pitch adjustment assembly 121 engages with the slide groove 123, thereby achieving the guiding effect between the pitch adjustment assembly 121 and the mounting base 12.

[0040] Reference Figure 2 and Figure 3 The top of the mounting base 1 is also slidably connected to a galvanometer 41, which can achieve sub-micron level positioning accuracy for the laser spot, ensuring the number of measurement samples, so that the measurement data can closely approximate the real data.

[0041] Reference Figure 2 and Figure 3 The galvanometer part 4 includes a galvanometer 41, and a galvanometer clip 42 is attached to the bottom of the galvanometer 41. The galvanometer clip 42 can fix the lateral position of the galvanometer 41, so that the distance between the galvanometer 41 and the object to be measured can be adjusted to increase the number of samples.

[0042] Reference Figure 2 and Figure 3 Laser rangefinders 3 are equidistantly placed on both sides of the laser marking unit 2. Because the laser rangefinders 3 measure the straightness of the two ends of the laser spot, the error caused by the laser spot of the laser marking unit 2 not being perpendicular to the positioning wall is avoided. The position of the adjustment module moves to enlarge or reduce the length range of the straightness measured by the two laser rangefinders 3, and measures objects of different sizes. The screws 52 provided on the mounting base 1 simultaneously adjust the distance between the laser rangefinders 3 and the laser marking unit 2 at equal distances.

[0043] Reference Figure 2 and Figure 3The distance adjustment module 5 includes two fixed bases 51 fixed on both sides. A laser rangefinder 3 is bolted to the top of the fixed base 51. A locking positioning piece 122 is bolted to the mounting base 12. A screw 52 is connected through the two fixed bases 51. The two ends of the screw 52 are hinged to the mounting base 1. The threaded end of the screw 52 includes opposite threaded sections 521. Specifically, the threaded section 521 has an arc-shaped cross-section: the pitch is 10mm and the arc radius is 2mm.

[0044] After the sliding adjustment is completed, the movable end of the locking positioning component 122 and the fixed base 51 are in a fixed connection relationship.

[0045] Optionally, the distance between the two mounting bases 1 can be 100mm, 200mm, or 200mm. For details, please refer to [reference needed]. Figure 3 The distance between the two mounting bases 1 is 200mm.

[0046] Reference Figure 2 and Figure 3 The drive end of the screw 52 is equipped with an adjustment head 522. When the adjustment head 522 rotates clockwise, the distance between the two laser rangefinders 3 decreases; when the adjustment head 522 rotates counterclockwise, the distance between the two laser rangefinders 3 increases.

[0047] The implementation principle of a laser marking device with line length marking function in this application embodiment is as follows: The support leg 11, mounting base 12, and telescopic support rod 13 are assembled; the laser marking unit 2 is installed in the mounting groove 1212 on the mounting base 12, ensuring that it can be adjusted in pitch around the hinge point. The pitch angle is adjusted to 0°, and the adjusting head 522 is rotated so that the two threaded sections 521 with opposite directions of rotation control the distance between the laser rangefinders 3 respectively; (Reference) Figure 3 Specifically, the distance between the laser rangefinders 3 was adjusted to 200mm, and finally the straightness parameters of the laser rangefinders 3 and the line length parameters of the galvanometer 41 were read as experimental data.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
