Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laser welding, in particular to a track type laser welding vehicle lamp device. Background Art
[0002] Track laser welding, also known as sequential axis welding, is a common laser welding method. This welding method involves the relative movement of the weldment and the laser beam along a predetermined route to complete the welding. The advantages of track laser welding are its low processing cost and reduced process damage. During the welding process, as the laser beam moves, the welding material will melt and then cool and solidify, forming a strong weld. In addition, the movement of the laser beam can be completed by a robot, further improving production efficiency and precision. In recent years, with the continuous advancement of laser technology, laser welding has gradually become an important process in the manufacture of automotive lights, especially suitable for the welding of automotive lights.
[0003] When performing track laser welding on existing headlights, in order to prevent displacement during welding, they are limited and fixed by clamps. However, due to the complex shape of automobile headlights and the fact that the welding position is located at the outermost periphery of the headlights, it is necessary to ensure that the headlight body and lampshade are clamped tightly during the welding process, and that the clamp does not block the laser from irradiating the welding position. Usually, a fixed tool is clamped against the edge. However, this type of clamping has a poor clamping effect due to the small contact area, so it needs to be improved. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] like Figure 1-5As shown, the utility model provides a technical solution: a track-type laser welding vehicle lamp device, comprising a welding table 1, a welding assembly is arranged on the top surface of the welding table 1, a track assembly is arranged on the top surface of the welding table 1, a fixing assembly is arranged on the top surface of the welding table 1, a placing assembly is arranged on the top surface of the welding table 1, and a gas purification assembly is arranged on the top surface of the welding table 1;
[0028] The placement assembly includes a jig 6 and a rubber strip 12 . The jig 6 is fixedly installed at the middle end of the top surface of the welding table 1 . A placement groove is opened on the top surface of the jig 6 , and a circle of rubber strip 12 is fixedly connected to the inner wall of the placement groove.
[0029] According to the overall structure of the device, after the lampshade and the shell of the headlight to be welded are spliced, they are placed in the placement groove of the fixture 6, against the rubber strip 12, and then the electromagnet 10 adsorbs the magnetic block 11 to shrink the movable rod of the telescopic rod 9, so that the clamping plate 8 can press the top surface of the headlight and squeeze the rubber strip 12 to increase the fixing effect. Then, the CCD visual component 5 is kept in the position where the weld can be observed through the mechanical arm 7 and displayed on the console 4, so that the operator can observe the welding situation. At the same time, the console 4 can keep the three-axis robot 2 moving along the weld track, so that the laser welding head 3 can move along the weld track and weld the weld. During welding, since the splint 8 is a laser transparent plate, the laser will not be lost or blocked. At the same time, when the laser welding head 3 passes through the splint 8, the emitted laser will first be deflected by the refraction plate 13, and then deflected by the splint 8, so that the laser emitted by the laser welding head 3 can maintain an angle with the weld and will not be offset by the splint 8. During welding, one end of the L-shaped tube 16 can be connected to the exhaust fan through a hose, so that the gas generated by welding can enter the L-shaped tube 16 from the nozzle 15, and be discharged after being filtered by the activated carbon filter 17. After welding is completed, the magnetic pole can be changed by the electromagnet 10 to make the magnetic block 11 rise, and the splint 8 no longer presses the car light.

The control console 4 is fixedly installed on one end of the top surface of the welding table 1.
[0031] By setting up the three-axis robot 2, laser welding head 3, robotic arm 7, CCD vision component 5 and control console 4, the CCD vision component 5 can be kept at a position where the weld can be observed through the robotic arm 7 and displayed on the control console 4, so that the operator can observe the welding situation. At the same time, the control console 4 can keep the three-axis robot 2 moving along the weld trajectory, so that the laser welding head 3 can move along the weld trajectory and weld the weld.
[0032] like Figure 3-4 As shown, the fixed component includes a telescopic rod 9 and a splint 8, the telescopic rods 9 are fixedly installed at both ends of the top surface of the welding table 1, the upper end of the arc-shaped surface of the movable rod of the telescopic rod 9 is fixedly connected with the splint 8 through a sleeve rod, the splint 8 is a laser transparent plate, the inner wall of the telescopic rod 9 is provided with a driving component, the top surface of the movable rod of the telescopic rod 9 is provided with a refractive component, the driving component includes a magnetic block 11 and an electromagnet 10, the bottom surface of the movable rod of the telescopic rod 9 is fixedly installed with a magnetic block 11, and the bottom surface of the inner wall of the telescopic rod 9 is fixedly installed with an electromagnet 10.
[0033] By setting the telescopic rod 9, the clamping plate 8, the magnetic block 11 and the electromagnet 10, when the headlight is placed in the placement groove of the fixture 6, the electromagnet 10 can adsorb the magnetic block 11 to shrink the movable rod of the telescopic rod 9 so that the clamping plate 8 can press the top surface of the headlight.
[0034] like Figure 3 As shown, the deflection assembly includes a deflection plate 13 and a connecting rod 14. The connecting rod 14 is fixedly installed on the top surface of the movable rod of the telescopic rod 9, and one end of the connecting rod 14 is fixedly connected to the deflection plate 13 through a connecting frame.
[0035] By setting the deflection plate 13 and the connecting rod 14, when the laser welding head 3 passes through the clamping plate 8, the emitted laser will first be deflected by the deflection plate 13 and then deflected by the clamping plate 8, so that the laser emitted by the laser welding head 3 can maintain an angle with the weld and will not be offset by the clamping plate 8.
[0036] like Figure 5 As shown, the gas purification component includes a suction nozzle 15, an L-shaped tube 16 and an activated carbon filter 17. The L-shaped tube 16 is fixedly installed on one end of the top surface of the welding table 1 through a bracket. The suction nozzle 15 is fixedly installed on one end of the L-shaped tube 16, and a plurality of activated carbon filters 17 are fixedly installed on the inner wall of the L-shaped tube 16.
[0037] By providing the suction nozzle 15, L-shaped tube 16 and activated carbon filter 17, during welding, one end of the L-shaped tube 16 can be connected to the exhaust fan through a hose, so that the gas generated by welding can enter the L-shaped tube 16 from the suction nozzle 15, and be discharged after being filtered by the activated carbon filter 17.

At the same time, the console 4 can keep the three-axis robot 2 moving along the weld track, so that the laser welding head 3 can move along the weld track. The trajectory moves and the weld is welded. When the laser welding head 3 passes through the clamping plate 8, the emitted laser will first be deflected by the refraction plate 13 and then deflected by the clamping plate 8, so that the laser emitted by the laser welding head 3 can maintain an angle with the weld. During welding, one end of the L-shaped tube 16 can be connected to the exhaust fan through a hose, so that the gas generated by welding can enter the L-shaped tube 16 from the suction nozzle 15, and be discharged after being filtered by the activated carbon filter 17. After welding is completed, the magnetic pole can be changed by the electromagnet 10 to make the magnetic block 11 rise, and the clamping plate 8 no longer presses the car light.
