Description

Technical Field

[0001] This utility model belongs to the field of welding head technology, specifically, it relates to an intelligent thin plate seamless welding head. Background Technology

[0002] In traditional thin plate welding processes, problems such as concentrated welding heat input and uniform weld spot morphology can easily lead to defects such as workpiece deformation and poor weld formation. This is especially prominent in high-precision machining fields (such as electronic components and medical devices). Existing welding heads mostly adopt fixed optical path designs, and weld spot adjustment relies on external mechanical structure adjustments. The response speed is slow and the accuracy is limited, making it difficult to adapt to complex weld trajectories or dynamic process requirements.

[0003] To address the above problems, this utility model proposes an intelligent thin-plate seamless welding head. Utility Model Content

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this embodiment provides an intelligent thin-plate traceless welding head, including: a galvanometer cavity seat 1.

[0027] like Figure 1-4As shown, in this embodiment, a QBH interface 2 is provided on the top of the galvanometer cavity 1, and a focusing lens 9 is provided on one side of the bottom of the galvanometer cavity 1. Below the QBH interface 2, inside the galvanometer cavity 1, a collimation protection drawer 4 is provided. Below the collimation protection drawer 4, a collimation lens drawer 5 is provided. Below the collimation lens drawer 5, an X-axis swing motor 17 is provided. A Y-axis swing motor 3 is provided on the front of the collimation protection drawer 4 and the collimation lens drawer 5. A reflector 16 is provided on the right side of the Y-axis swing motor 3. Below the reflector 16, inside the focusing lens 9, a focusing lens drawer 11 is provided. Below the focusing lens drawer 11, a protective lens drawer 12 is provided. A coaxial air cylinder 13 is installed at the bottom of the focusing lens 9, and a copper nozzle 14 is installed at the bottom of the coaxial air cylinder 13. The collimation lens drawer 5 and the focusing lens drawer 11 contain corresponding laser lenses, while the collimation protection drawer 4 and the protective lens drawer 12 contain corresponding protective lenses to protect the corresponding laser lenses and prevent damage during operation. Splashes, dust, and debris enter the galvanometer cavity 1 to protect the internal optical components. The QBH connector 2 connects to and fixes the fiber laser. The laser is emitted from inside the fiber and received and shaped by the lens inside the collimating lens drawer 5. The laser is then directly projected onto the reflection module on the X-axis oscillating motor 17. The high-frequency oscillation of the X-axis oscillating motor 17 causes the reflecting lens to reflect the laser back to the reflection module on the Y-axis oscillating motor 3. Similarly, the Y-axis oscillating motor 3 causes the laser to be reflected a second time, reaching the reflecting mirror 16 module for a third reflection. After passing through the lens inside the focusing lens drawer 11, a focused energy focal point is formed. Finally, the laser passes downward through the coaxial air cylinder 13 and is ejected from the copper nozzle 14 to strike the welding object for welding. The oscillation frequency signals of the X-axis output motor 17 and the Y-axis output motor 3 can be used to transform the focal point from a dot into a pattern, realizing the transformation of the weld spot. It can be adjusted to transform into a circle, square, straight line, spiral, concentric circle, etc., as needed.

[0028] like Figure 1 , 2 As shown, in this embodiment, a handle 8 is provided on the top of the galvanometer cavity seat 1 on the other side of the QBH interface 2. An operation screen 10 is provided on the front of the galvanometer cavity seat 1, and a mounting plate 20 is provided on the back of the galvanometer cavity seat 1. A signal interface 15 is provided on the top of the galvanometer cavity seat 1 near the back. The handle 8 has a corresponding reset button and a self-locking switch to facilitate the installation and debugging of the welding head. The two internal swing motors are connected to the operation screen 10 through wiring and are adjusted through the operation screen 10. The entire welding head is connected to the corresponding DB25 connector through the signal interface 15 to transmit data with the outside.

[0029] like Figure 4As shown, in this embodiment, the collimation protection drawer 4 and the collimation lens drawer 5 can be pulled out from the galvanometer cavity seat 1, and the focusing lens drawer 11 and the protective lens drawer 12 can be pulled out from the focusing lens seat 9. The drawer-type installation makes it easier and more convenient to remove and place the lens, and allows for quick replacement, thus improving the maintenance efficiency of the lens.

[0030] like Figure 4 As shown, in this embodiment, a cooling water outlet 6 and a cooling water inlet 7 are provided on one side of the galvanometer cavity seat 1. A water flow cover 22 is provided at the bottom of the galvanometer cavity seat 1 corresponding to the cooling water outlet 6 and the cooling water inlet 7. Cooling water enters from the cooling water inlet 7 below and flows through the pipes inside the galvanometer cavity seat 1 through the side wall and bottom of the galvanometer cavity seat 1. It absorbs the heat generated by the operation of the electronic components inside the galvanometer cavity seat 1 and cools it down. The water flow cover 22 can be removed to directly clean the water channel, which is convenient for subsequent maintenance.

[0031] like Figure 2 As shown, a gas pipe interface 18 is provided on one side of the focusing lens mount 9 in this embodiment; wherein, the gas pipe interface 18 is connected to the auxiliary gas required for welding. The auxiliary gas protection can effectively reduce the solute spatter generated during the welding process, protect the laser head lens from damage by spatter, and protect the weld from oxidation.

[0032] like Figure 2 , 3 As shown, in this embodiment, a collimation monitoring device 19 is provided on one side of the collimation protection drawer 4 and the collimation lens drawer 5, and a focusing monitoring device 21 is provided on one side of the focusing lens drawer 11 and the protective lens drawer 12. The corresponding monitoring device can observe the light transmission of the corresponding lens in real time. When the lens is contaminated, it feeds back to the control system panel and prompts an alarm. The operator immediately replaces the corresponding lens, thereby reducing the occurrence of welding quality degradation when the lens is damaged.

[0033] Working principle: A fixed fiber laser is connected via QBH connector 2. The laser is emitted from inside the fiber and received and shaped by the lens inside the collimating lens drawer 5. The laser beam is then directed onto the reflection module on the X-axis oscillating motor 17. The high-frequency oscillation of the X-axis oscillating motor 17 causes the reflecting lens to reflect the laser beam onto the reflection module of the Y-axis oscillating motor 3. Similarly, the Y-axis oscillating motor 3 causes the laser beam to be reflected a second time, reaching the reflecting mirror 16 module for a third reflection. After passing through the lens inside the focusing lens drawer 11, a focused energy focal point is formed. Finally, the laser beam passes downward through the coaxial air cylinder 13 and is ejected from the copper nozzle 14 to strike the welding object for welding. The oscillation frequency signals of the X-axis output motor 17 and the Y-axis output motor 3 can transform the focal point from a dot into a pattern, thus realizing the transformation of the weld spot.
