Technical Field

[0001] The utility model relates to the technical field of laser marking machines, in particular to a laser marking machine. Background Art

[0002] A laser marking machine uses a laser beam to permanently mark the surfaces of various materials. The marking effect is achieved by evaporating the surface material, revealing the underlying material, thereby creating exquisite designs, trademarks, and text. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines, and YAG laser marking machines. Laser marking machines are primarily used in applications requiring higher precision and precision. They are used in electronic components, integrated circuits (ICs), electrical appliances, mobile phones, hardware products, tool accessories, precision instruments, eyewear and watches, jewelry, automotive parts, plastic buttons, building materials, and PVC pipes.

[0003] Currently, existing laser marking machines generally use a fan heat dissipation mode, but this heat dissipation mode requires opening holes in the laser marking machine, which makes it easy for dust to enter the interior of the laser marking machine, thereby affecting the working efficiency and service life of the laser marking machine.

[0004] Therefore, a laser marking machine is proposed. Utility Model Content

[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] Example 1:

[0035] See also Figure 1 、 4-7, the utility model provides a technical solution: In order to achieve the above purpose, the utility model provides the following technical solutions: a laser marking machine, comprising: a base 1; a lifting frame 2 is installed on the top of the base 1, a mounting plate 3 is provided on the lifting frame 2, a laser marking machine body 4 is installed on the top of the mounting plate 3; a laser head 5 is installed at one end of the laser marking machine body 4; a heat dissipation strip 6 is provided on the top of the laser marking machine body 4, a heat dissipation channel 7 is opened inside the heat dissipation strip 6, and a water inlet pipe 8 and a water outlet pipe 9 connected to the heat dissipation channel 7 are respectively installed on the outer wall of the heat dissipation strip 6; the water inlet pipe 8 is connected to the external cold water pipe, the water outlet pipe 9 is connected to the external circulation equipment, and the bottom of the heat dissipation strip 6 is fixed with a connection Frame 19, the connecting frame 19 is arranged outside the laser marking machine body 4, and a first clamping hole 20 is opened on the outer wall of the connecting frame 19, and a second clamping hole 21 is opened on the outer wall of the laser marking machine body 4; a fixing rod 22 is clamped in the first clamping hole 20 and the second clamping hole 21, and an auxiliary plate 23 is fixed to one end of the fixing rod 22, and a spring 24 is provided on the outer wall of the fixing rod 22, one end of the spring 24 is fixed to the auxiliary plate 23, and the other end of the spring 24 is fixed to the connecting frame 19, a sealing sleeve 16 is provided on the outside of the laser head 5, and an internal thread 18 is provided on the inner wall of the sealing sleeve 16, and an external thread 17 is provided on the outer wall of the laser head 5; the sealing sleeve 16 is threadedly connected to the outside of the laser head 5 through the internal thread 18 and the external thread 17.

[0036] Specifically, since a heat dissipation strip 6 is provided on the top of the laser marking machine body 4, a heat dissipation channel 7 is opened inside the heat dissipation strip 6, and a water inlet pipe 8 and a water outlet pipe 9 connected to the heat dissipation channel 7 are respectively installed on the outer wall of the heat dissipation strip 6, the water inlet pipe 8 is connected to the external cold water pipe, and the water outlet pipe 9 is connected to the external circulation equipment, so as long as the external cold water pipe is connected, the cold water in the external cold water pipe will enter the heat dissipation channel 7 in the heat dissipation strip 6 through the water inlet pipe 8, and the cold water will cooperate with the heat dissipation strip 6 to dissipate heat for the laser marking machine body 4. Compared with the existing method, the utility model avoids opening holes on the laser marking machine body 4 by changing the heat dissipation method of the laser marking machine body 4, thereby preventing dust from entering the interior of the laser marking machine body 4, thereby improving the working efficiency and service life of the laser marking machine body 4;

[0037] By pulling the fixing rod 22 through the auxiliary plate 23, the spring 24 will stretch.

Therefore, the utility model facilitates the maintenance of the heat dissipation bar 6 and improves the heat dissipation efficiency of the heat dissipation bar 6 to the laser marking machine body 4.

[0038] Since the sealing sleeve 16 is threadedly connected to the outside of the laser head 5 through the internal thread 18 and the external thread 17, when the laser head 5 is not in use, the sealing sleeve 16 can prevent dust from being adsorbed on the outside of the laser head 5, thereby improving the working efficiency and service life of the laser head 5.

[0039] Example 2:

[0040] See also Figure 1-3 The utility model provides a technical solution: a laser marking machine, a connecting ear 10 is fixed to the outer wall of the laser marking machine body 4, a first connecting hole 11 is opened on the top of the connecting ear 10, and a second connecting hole 12 is opened on the top of the mounting plate 3; a threaded member 13 is provided in the first connecting hole 11 and the second connecting hole 12, one end of the threaded member 13 is fixed with a limiting plate 14, and the outer wall of the threaded member 13 is threadedly connected to a limiting ring 15; one end of the limiting plate 14 abuts against the connecting ear 10, and one end of the limiting ring 15 abuts against the mounting plate 3.

Therefore, the utility model is convenient for maintaining the laser marking machine body 4 and has high practicality.

[0042] Working principle:

[0043] First, since the top of the laser marking machine body 4 is provided with a heat dissipation strip 6, a heat dissipation channel 7 is opened inside the heat dissipation strip 6, and the outer wall of the heat dissipation strip 6 is respectively installed with a water inlet pipe 8 and a water outlet pipe 9 connected to the heat dissipation channel 7, the water inlet pipe 8 is connected to the external cold water pipe, and the water outlet pipe 9 is connected to the external circulation equipment, so as long as the external cold water pipe is connected, the cold water in the external cold water pipe will enter the heat dissipation channel 7 in the heat dissipation strip 6 through the water inlet pipe 8, and the cold water will cooperate with the heat dissipation strip 6 to dissipate heat for the laser marking machine body 4. Compared with the existing method, the utility model avoids opening holes on the laser marking machine body 4 by changing the heat dissipation method of the laser marking machine body 4, thereby preventing dust from entering the interior of the laser marking machine body 4, thereby improving the working efficiency and service life of the laser marking machine body 4;

[0044] By pulling the fixing rod 22 through the auxiliary plate 23, the spring 24 will stretch. After one end of the fixing rod 22 is disengaged from the second clamping hole 21, the heat dissipation bar 6 can be disassembled. Therefore, the utility model facilitates the maintenance of the heat dissipation bar 6 and improves the heat dissipation efficiency of the heat dissipation bar 6 to the laser marking machine body 4.

[0045] Since the sealing sleeve 16 is threadedly connected to the outside of the laser head 5 through the internal thread 18 and the external thread 17, when the laser head 5 is not in use, the sealing sleeve 16 can prevent dust from being adsorbed on the outside of the laser head 5, thereby improving the working efficiency and service life of the laser head 5;

[0046] Secondly, by rotating the limit ring 15 and disengaging it from the outer wall of the threaded member 13, and then taking the threaded member 13 out of the first connecting hole 11 and the second connecting hole 12, the laser marking machine body 4 can be disassembled. Therefore, the utility model is convenient for maintaining the laser marking machine body 4 and has high practicality.
