Description

Technical Field

[0001] This utility model relates to the field of laser marking calibration technology, and in particular to a laser marking calibration mechanism. Background Technology

[0002] Laser marking is a method of making permanent marks on the surface of an object using laser technology. A laser marking calibration institution is a device specifically used to calibrate and adjust the marking accuracy and positional accuracy of a laser marking machine. Its main function is to ensure that the laser marking machine can accurately focus the laser beam at the expected position when it is working.

[0003] By adjusting the distance between the workpiece and the marking instrument, and using a calibration method, the distance between the workpiece and the marking instrument is adjusted to a suitable distance for marking, and finally the marking is performed.

[0004] Existing laser marking calibration mechanisms require manual adjustment of the distance between the marking instrument and the workpiece before marking, thus they cannot automatically adjust the distance between the workpiece and the marking instrument, and also lack the function of measuring the distance between the workpiece and the marking instrument. Therefore, a new laser marking calibration mechanism has emerged. Utility Model Content

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1

[0028] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a laser marking calibration mechanism, including a base 1, a lifting mechanism 2 on the top of the base 1, and a marking mechanism 3 adapted to the lifting mechanism 2 on the top of the base 1.

[0029] Specifically, the lifting mechanism 2 includes a hollow column 201 fixedly installed on the top of the base 1. The hollow column 201 has a hole top rod 208 inside. A bearing plate 206 is fixedly installed on the top of the hole top rod 208. Several protrusion blocks 207 are evenly distributed on the top of the bearing plate 206.

[0030] Specifically, a motor 202 is fixedly installed on the top of the base 1. A first flipping rod 204 is fixedly sleeved on the output end of the motor 202. A second flipping rod 205 is rotatably connected inside the first flipping rod 204. A limit shaft 209 is fixedly connected to the inner surface of the hollow column 201. A spring 210 is fixedly installed at the bottom of the hole top rod 208. A fixing plate 203 is provided on one side of the output end of the motor 202. There are four hollow columns 201, which are symmetrically installed on the top of the base 1. The hole top rod 208 is movably inserted into the inside of the hollow column 201. The second flipping rod 205 is rotatably connected to the center of the bottom of the bearing plate 206. The hole top rod 208 is slidably connected inside the hole top rod 208.

[0031] Furthermore, the operation of the control motor 202 causes the end of the first flipping rod 204 connected to the second flipping rod 205 to flip upward. Since one end of the second flipping rod 205 is rotatably connected to the bottom of the support plate 206, the end of the second flipping rod 205 rotatably connected to the first flipping rod 204 flips in the same direction as the first flipping rod 204, pushing the support plate 206 upward. When the support plate 206 moves upward, it drives the hole top rod 208 to move upward, thereby changing the deformation of the spring 210. Under the action of the limiting shaft 209, the moving length of the hole top rod 208 is limited, which has the function of pushing the support plate 206 to move upward smoothly. Under the action of several protrusion blocks 207, the friction between the protrusion block and the marking workpiece is increased.

[0032] Example 2

[0033] Reference Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment and includes a marking mechanism 3 for marking workpieces.

[0034] Specifically, the marking mechanism 3 includes a fixed frame 302 and a marking instrument 304. A bracket 306 is fixedly installed on one side of the fixed frame 302, and a display screen 307 is provided at the end of the bracket 306 away from the fixed frame 302. A rangefinder 305 is fixedly installed on one side of the marking instrument 304.

[0035] Specifically, the top of the mounting bracket 302 is provided with a wire harness tube 303, the top of the base 1 is provided with a control console 301, the bracket 306 has a three-fold design and is connected to the back of the display screen 307 using a mounting bracket, and the bottom of the mounting bracket 302 is fixedly installed on the top of the base 1 by bolts.

[0036] Furthermore, the base 1 is equipped with a computer host and keyboard, the structure of which is the same as that of the existing disclosed ones. The host is connected to the display screen 307 and the keyboard via a wiring harness. The mouse is not shown in the figure. The workpiece to be marked is placed on top of several protrusion blocks 207. Since the rangefinder 305 and the marking instrument 304 are both connected to the host via a wire harness, the distance between the bottom of the marking instrument 304 and the top of the workpiece to be marked is measured by the rangefinder 305. The host transmits the data to the marking instrument 304 for marking. Thus, it has the function of measuring the distance between the workpiece and the marking instrument 304.

[0037] Working principle: The workpiece to be marked is placed on top of several raised blocks 207. According to the marking parameters, the distance from the workpiece to the marking instrument 304 is measured by the rangefinder 305. When the distance needs to be adjusted, the motor 202 is controlled to operate. The motor 202 drives the first rotating rod 204 to rotate, and the first rotating rod 204 drives the second rotating rod 205 to rotate, thereby moving the support plate 206. If the end of the first rotating rod 204 away from the motor 202 rotates upward, the support plate 206 is pushed upward by the second rotating rod 205. If the end of the first rotating rod 204 away from the motor 202 rotates downward, the support plate 206 is pushed upward by the second rotating rod 205. The second flipping rod 205 pulls the support plate 206 downward. As the support plate 206 moves as needed, it drives the hole push rod 208 to move in the hollow column 201. Under the action of the limiting shaft 209, the hole push rod 208 is kept moving up and down in the hollow column 201. The distance between the workpiece and the marking instrument 304 is adjusted as needed. After the adjustment is completed, the status parameters after adjustment can be observed through the display screen 307. At this time, the operation of the marking instrument 304 is controlled by the relevant marking parameters displayed on the display screen 307, and the marking instrument 304 can mark the surface of the workpiece.

[0038] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
