Each welding device adjusts the position of the welding head for welding, and the welding is carried out by multiple independent devices. This makes the welding processing cost high and occupies a large area of the factory building, resulting in a poor processing experience and being not conducive to improving the competitiveness of the enterprise.

This embodiment is inclined, and the two groups of laser welders 3 are symmetrical to each other.

[0023] With the arrangement of two groups of laser welders 3, the two sides of the product to be welded can be welded simultaneously, further improving the processing efficiency. There is no need for two separate devices to weld the two side arc surfaces respectively. And with the arrangement of the three-dimensional driving device, the laser focus point can be adjusted according to the components at different welding positions, with higher flexibility.

[0024] The semi-automatic laser welding mechanism further includes a transfer welding platform 4. The number of processing and transporting belt assemblies 2 is two. The transfer welding platform 4 is arranged at the end of the processing and transporting belt assemblies 2. The processing and transporting belt assemblies 2 can transfer the product fixture 5 to the transfer welding platform 4. The transfer welding platform 4 can cooperate with the two groups of laser welders 3 for welding. And a transfer mechanism is arranged on the transfer welding platform 4, which can transfer the material to another group of processing and transporting belt assemblies 2 for discharging in cooperation.

[0025] The laser welding of the product can be conveniently and accurately carried out through the transfer welding platform 4.

[0026] The two processing and transporting belt assemblies 2 are arranged side by side, and the transporting directions of the two processing and transporting belt assemblies 2 are opposite. The transfer mechanism includes an X-axis pusher assembly and a Y-axis pusher assembly.

[0027] The Y-axis pusher assembly includes a Y-axis pusher cylinder 61 and a Y-axis pusher plate 62. The Y-axis pusher cylinder 61 is arranged perpendicular to the transporting direction of the processing and transporting belt assembly 2. The Y-axis pusher plate 62 is fixedly connected to the moving end of the Y-axis pusher cylinder 61.

[0028] The X-axis pusher assembly includes an X-axis pusher cylinder 71 and an X-axis pusher plate 72. The moving direction of the moving end of the X-axis pusher cylinder 71 is the same as the transporting direction of the processing and transporting belt assembly 2. The X-axis pusher plate 72 is fixedly connected to the moving end of the X-axis pusher cylinder 71.

[0029] A transfer blocking component is arranged on the Y-axis pusher plate 62, which can prevent the feeding of the processing and transporting belt assembly 2 from causing interference to the transfer position during the transfer of the Y-axis pusher assembly.

[0030] The transfer blocking component includes a transfer baffle 8 and transfer rollers. The transfer rollers are fixedly arranged on the transfer baffle 8, and the transfer rollers can reduce the wear between the transfer baffle 8 and the product fixture 5.

[0031] A position inductor 41 is arranged on the transfer welding platform 4, which is used to sense whether the processing and transporting belt assembly 2 transports the product fixture 5 to the designated position on the transfer welding platform 4.

[0032] The welding three-dimensional driving device includes an X-axis linear driving module 9, a Y-axis linear driving module 10 and a Z-axis linear driving module 11.

[0033] The semi-automatic laser welding mechanism also includes a welding positioning assembly, which includes a positioning drive device 121 and a positioning plate 122. The positioning plate 122 is fixedly connected to the moving end of the positioning drive device 121. The positioning plate 122 is provided with a positioning pin, which can be inserted into the product fixture 5 for positioning.

[0034] The working process of the semi-automatic laser welding mechanism provided in this embodiment is as follows: The embodiment of the utility model provides a method for realizing laser welding processing of parts compared with existing products, and has the advantages of high degree of integration and high processing efficiency.

[0035] First, the processing personnel load the product arc-shaped steel sheet into the product jig 5, which is provided with a plurality of parts placement positions, and the parts to be welded are placed on the parts placement positions, waiting to be welded on the arc-shaped steel sheet.

[0036] After the assembly is completed, the processing personnel put the product jigs 5 one by one into the processing and transport belt assembly 2 for loading.

[0037] The processing and transporting belt assembly 2 gradually transports the material to the transfer and welding platform 4 until the in-place sensor 41 detects that the product fixture 5 has moved to the specified position of the transfer and welding platform 4, and then the positioning drive device 121 drives the positioning plate 122 to move downward to press the upper end surface of the product fixture 5, and the positioning pin is inserted into the pin hole on the product fixture 5 to achieve positioning.

[0038] After positioning is completed, the setting angles of the two groups of laser welders 3 are locked. The two groups of laser welders 3 operate according to the pre-programmed program to weld each part one by one. Each part is welded on both sides at the same time. After welding is completed, the focus of the laser welder 3 is adjusted by the welding three-dimensional drive device to continue welding the next part.

[0039] After welding is completed, the positioning drive device 121 drives the positioning plate 122 to move upward and reset.

[0040] After the reset is completed, the Y-axis push cylinder 61 drives the Y-axis push plate 62 to move toward the X-axis push assembly.

[0041] After the material is pushed, the X-axis pushing cylinder 71 drives the X-axis pushing plate 72 to push the material onto the processing and transporting belt assembly 2 for unloading, completing the unloading action, and the processing is cyclically carried out in this way.

[0042] During the pushing process of the Y-axis pushing cylinder 61, since the processing and transporting belt assembly 2 used for loading materials is continuously running, the setting of the material transfer and blocking assembly can limit the prevention of the processing and transporting belt assembly 2 from continuing to feed materials to the material transfer and welding platform 4, thereby avoiding affecting the pushing action of the Y-axis pushing cylinder 61.

[0043] With its mechanism, it can effectively solve the problems of high welding cost and low welding processing efficiency in the welding processing method of multiple welding devices in the prior art. By using this product structure, two groups of laser welders 3 can weld both sides of the part simultaneously, and through the welding three-dimensional driving device, it can adjust the focus welding according to the positions of different parts, improving the integration of welding processing, avoiding the independent welding of traditional multiple welding devices, effectively reducing the occupied area, and effectively improving the processing efficiency, which is beneficial to enhancing the competitiveness of the enterprise.

All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
