Description

Technical Field

[0001] The utility model relates to a multi-adaptive laser linear automatic welding device, belonging to the technical field. Background Art

[0002] In the existing laser handheld welding process, there is a widespread demand for large-scale consistent straight seam welding. However, the currently commonly used manual handheld welding method has many problems. Not only is the high repetitiveness of the process operation leading to low manual operation efficiency and fatigue, but it also causes defects such as unstable welding, which greatly affects the welding quality.

[0003] At present, there are only automatic welding devices for laser welding systems such as CN106392317B and a manual-automatic integrated laser welding machine such as CN112388161A that can solve the efficiency problem of automation. However, these devices are only suitable for welding operations on flat equipment to be welded from a top-down perspective. When encountering equipment with more complex spatial structures such as welds, welding operations cannot be performed due to the positioning angle limitations of the laser welding gun. The welding angle of the laser welding gun cannot be adjusted according to the spatial environment, resulting in poor flexibility. In addition, the space occupied by this type of equipment is too large, and it is difficult to arrange it in batches during actual production, and its applicability is relatively limited. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a multi-adaptive laser linear automatic welding device, comprising:

[0005] A feeding assembly, including a stepper motor and a linear module connected to the stepper motor;

[0006] A welding assembly, comprising a fixed seat mounted on the linear module, a lifting assembly connected to the fixed seat, and a universal adjustment mechanism mounted on the lifting assembly, wherein the universal adjustment mechanism has at least three rotating seats and is connected to a laser welding gun capable of acting on the weld;

[0007] A control box is connected to the feeding assembly and the welding assembly. The control box is integrated with a PCB board and an MCU logic controller and is equipped with an alarm device. The PCB board and the MCU logic controller allow communication with the laser of the laser welding gun, the universal adjustment mechanism, and the stepping motor to control the laser signal setting, the operating angle and feeding movement of the laser welding gun. It should be understood that the control box can also control the feeding movement of the welding assembly on the linear module and control its feeding speed.

[0008] Furthermore, the linear module includes a linear track arranged along the direction of the weld and a strong magnetic attraction configured on the linear track, and the linear module allows the welding assembly to perform linear reciprocating motion.

[0009] Furthermore, the lifting assembly includes a lifting rod fixed to the fixing seat, a connecting ring sleeved on the lifting rod, and the connecting ring is connected to the universal adjustment mechanism. The universal adjustment mechanism includes a first rotating seat, a second rotating seat, a third rotating seat, and a supporting fixed block connected to the connecting ring in sequence, and the first rotating seat, the second rotating seat, and the third rotating seat are respectively allowed to drive the supporting fixed block to rotate in three different planes. The supporting fixed block has a freely adjustable clamping claw, and the clamping claw detachably fixes the laser welding gun.

[0010] In some embodiments of the utility model, the first rotating seat allows the second rotating seat, the third rotating seat, the support fixing block and the laser welding gun to rotate within a 60-degree elevation angle in a first plane perpendicular to the horizontal plane. Further, the second rotating seat allows the third rotating seat, the support fixing block and the laser welding gun to rotate within a 45-degree swing angle in a second plane perpendicular to the first plane.

[0021] Example 1

[0022] like Figure 1-Figure 3 The utility model provides a multi-adaptive laser linear automatic welding device, comprising:

[0023] The feeding assembly 1 includes a stepping motor 11 and a linear module connected to the stepping motor 11; the linear module includes a linear track 12 arranged along the welding seam direction and a strong magnetic attraction 13 arranged on the linear track, and the linear module allows the welding assembly 2 to perform linear reciprocating motion; the linear module is also provided with a limiting device;

The lifting assembly includes a lifting rod 22 fixed to the fixed seat, a connecting ring 23 sleeved on the lifting rod 22, and the connecting ring 23 is connected to the universal adjustment mechanism. The universal adjustment mechanism includes a first rotating seat 24, a second rotating seat 25, a third rotating seat 26, and a supporting fixed block connected to the connecting ring 23 in sequence. The first rotating seat 24, the second rotating seat 25, and the third rotating seat 26 are respectively allowed to drive the supporting fixed block to rotate in three different planes. The supporting fixed block has a freely adjustable clamping jaw 27, and the clamping jaw 27 detachably fixes the laser welding gun 6;

[0025] The control box 3 is connected to the feeding assembly 1 and the welding assembly 2. The control box 3 has a start button, a speed adjustment button, a laser signal button and an emergency stop button. The control box 3 integrates a PCB board and an MCU logic controller and is equipped with an alarm device. The PCB board and the MCU logic controller allow communication with the laser of the laser welding gun 6, the universal adjustment mechanism, and the stepping motor 11, and control and give laser signals, the operating angle and feeding movement of the laser welding gun 6. The control box 3 can also control the welding assembly 2 to feed and move on the linear module and control its feeding speed.

[0026] The first rotating seat 24 allows the second rotating seat 25, the third rotating seat 26, the support fixing block and the laser welding gun 6 to rotate within a 60-degree elevation angle in a first plane perpendicular to the horizontal plane. Further, the second rotating seat 25 allows the third rotating seat 26, the support fixing block and the laser welding gun 6 to rotate within a 45-degree swing angle in a second plane perpendicular to the first plane.

[0027] The working principle of this utility model:

[0028] Step 1: placing the workpiece 4 on a designated workbench, and limiting the stroke length of the welding assembly to be fed later by a limiting device according to the length of the weld 5 to be welded in the workpiece 4;

[0029] Step 2: Control the first rotating seat 24, the second rotating seat 25, the third rotating seat 26 of the universal adjustment mechanism and the lifting rod 22 and the connecting ring 23 of the lifting assembly through the control box 3 to adjust the laser welding gun 6 to the position of the weld 5, and control the fixed seat 21 to drive the universal adjustment mechanism to slide to the initial position of the linear track 12 to prepare for welding the weld 5;
