[0002] In modern manufacturing, with the increasing demand for high-precision and high-reliability welding, traditional processes such as electric arc welding and resistance welding have limitations such as large thermal deformation and low efficiency when facing complex welding scenarios such as precision electronic components and aerospace structural parts. Laser welding has emerged to address these limitations. It is an advanced welding technology that uses a high-energy-density laser beam as a heat source and focuses the laser onto the part of the workpiece to be welded through a focusing lens, so that the local material melts rapidly and cools and solidifies, thereby achieving the connection of metal or non-metal materials. It has significant advantages such as fast welding speed, small heat-affected zone, high weld precision, and the ability to achieve automated control. It can complete micron-level precision welding and welding of refractory materials.

[0003] Existing conventional automatic laser welding equipment has some shortcomings in workpiece fixation and welding operation coordination. Some conventional equipment uses mechanical clamps to fix the workpieces to be welded. However, for workpieces with regular shapes, the adjustment of the clamps is relatively cumbersome.

[0004] Therefore, an automated laser welding device is proposed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] An automated laser welding device includes a control panel 1, a control structure 2 bolted to the right side of the top of the control panel 1, and a support structure 3 bolted to the left side of the top of the control panel 1.

[0027] The support structure 3 includes a mounting frame 31, a stabilizing platform 32, an adsorption plate 33, a connecting pipe 34, and a vacuum pump 35. The bottom of the mounting frame 31 is bolted to the left side of the top of the control panel 1, the top of the mounting frame 31 is bolted to the bottom of the stabilizing platform 32, the inner side of the stabilizing platform 32 is bolted to the outer side of the adsorption plate 33, the bottom of the adsorption plate 33 is bolted to the top of the connecting pipe 34, the bottom of the connecting pipe 34 is bolted to the top of the vacuum pump 35, and the vacuum pump 35 is located at the rear of the control panel 1.

[0028] In this embodiment: the control panel 1 serves as the basic platform for the entire automated laser welding device. The control panel 1 provides a stable mounting surface for the control structure 2 and the support structure 3. The support structure 3, including the mounting bracket 31, provides stable support for the stabilizing platform 32 and the adsorption plate 33, securely mounting the support structure 3 onto the control panel 1. The stabilizing platform 32 enhances the stability of the connection, providing a movable contact surface for the laser welding head 24 at the top, while the adsorption plate 33 is bolted to the inside to fix the welding workpiece. The adsorption plate 33 uses the negative pressure generated by the vacuum pump 35 to firmly adsorb the welding workpiece onto the stabilizing platform 32, preventing the workpiece from moving or shaking during the welding process. The connecting pipe 34 serves as a gas transmission channel between the adsorption plate 33 and the vacuum pump 35, transmitting the negative pressure generated by the vacuum pump 35 to the adsorption plate 33. The vacuum pump 35 serves as the power source for adsorption, generating negative pressure by extracting air from the connecting pipe 34 and the adsorption plate 33, providing adsorption force for the adsorption plate 33.

[0029] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, the control structure 2 includes a horizontal and vertical axis mover 21, the bottom of which is bolted to the right side of the top of the control panel 1.

[0030] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a lifting controller 22 is bolted to the top of the horizontal and vertical axis mover 21, and a connecting frame 23 is bolted to the left side of the lifting controller 22.

[0031] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a laser welding head 24 is bolted to the left side of the connecting frame 23, and the bottom of the laser welding head 24 is movably connected to the top of the stabilizing platform 32.

[0032] In this embodiment: by setting up a control structure 2, wherein the horizontal and vertical axis mover 21 realizes the horizontal and vertical movement of the laser welding head 24 through an existing precise electric drive system, the set up lifting controller 22 realizes the vertical height adjustment of the laser welding head 24 by controlling the lifting action, the set up connecting bracket 23 is used for mounting the laser welding head 24 and transmits the movement of the lifting controller 22 to the laser welding head 24, the set up laser welding head 24 is connected to the laser welding head 24 through an existing laser generator, and focuses the laser energy onto the surface of the workpiece to be welded, and achieves welding by melting the metal at high temperature.

[0033] Specifically, such as Figure 1 , Figure 4 , Figure 5As shown, a mounting plate 4 is bolted to the rear side of the control panel 1, and the top of the mounting plate 4 is bolted to the bottom of the vacuum pump 35.

[0034] Specifically, such as Figure 2 As shown, the top of the stabilizing platform 32 has a mounting hole 5, and the adsorption plate 33 passes through the mounting hole 5 and is connected to the connecting pipe 34.

[0035] In this embodiment: the mounting plate 4 provides an installation position for the vacuum pump 35, and the vacuum pump 35 is firmly fixed to one side of the control panel 1. The mounting hole 5 opened by the stabilizing platform 32 facilitates the through connection of the adsorption plate 33 to the connecting pipe 34, thus providing an installation position for the adsorption plate 33 and the connecting pipe 34.

[0036] Specifically, such as Figure 2 As shown, four plug-in rods 6 are fixedly connected to the bottom of the stabilizing platform 32, and each plug-in rod 6 is located at the bottom of the stabilizing platform 32. The bottom of the plug-in rod 6 is plugged into the top of the mounting bracket 31.

[0037] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, the bottom of the control panel 1 is fixedly connected with four support feet 7, which are respectively located at the bottom of the control panel 1.

[0038] In this embodiment: by setting the plug rod 6 fixed at the bottom of the stabilizing platform 32, the connection strength between the stabilizing platform 32 and the mounting frame 31 is further enhanced; by setting the support foot 7, the stability of the control panel 1 in contact with the ground is improved, and the pressure generated during the operation of the device is dispersed.

[0039] Working principle: When this automated laser welding device is working, the workpiece to be welded is first placed on the adsorption plate 33 of the stabilizing platform 32. The vacuum pump 35 is started, and the vacuum pump 35 draws air out of the adsorption plate 33 through the connecting pipe 34, generating negative pressure so that the adsorption plate 33 firmly adsorbs the workpiece and prevents the workpiece from moving during the welding process. The horizontal and vertical axis movers 21 in the control structure 2 rely on a precise electric drive system to drive the laser welding head 24 to move horizontally and vertically, and the welding position can be flexibly adjusted. The lifting controller 22 is responsible for controlling the vertical height adjustment of the laser welding head 24 so that the laser welding head 24 reaches the appropriate welding height. The connecting frame 23 transmits the movement of the horizontal and vertical axis movers 21 and the lifting controller 22 to the laser welding head 24. When the laser welding head 24 is adjusted to the correct position and height, the connected laser generator generates laser energy, which is focused on the surface of the workpiece by the laser welding head 24, and the metal is melted by high temperature to realize the welding work.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
