[0002] Car headlights, also known as automotive headlights or automotive LED daytime running lights, are the eyes of a car. They not only affect the appearance of a car owner, but are also closely related to safe driving at night or in bad weather conditions. The welding process is also essential when manufacturing automotive lights. Therefore, a non-contact welding device for automotive lights is needed.

Maintaining a certain distance between the material and the lower and upper heating components ensures uniform heating of the material and avoids insufficient heat fusion leading to substandard welding quality, thus improving welding efficiency. This device has simple components, is easy to operate, facilitates later maintenance, and avoids welding overflow and welding bubbles affecting welding quality, thereby improving product quality. In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1.

The operation process is cumbersome, time-consuming, and labor-intensive, thus greatly reducing the convenience of using the non-contact welding device; 2. Some non-contact welding devices cannot fix the angle of the fixed lamp after rotating it, which makes the lamp prone to displacement or rotation during the welding process, thus greatly reducing the welding accuracy and causing the welding quality of the lamp to fail to meet the standards.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a non-contact welding device for automotive lamps, including a drive assembly 1, a mounting base 2 at the top center of the drive assembly 1, an electric motor 3 embedded inside the mounting base 2, a connecting shaft 4 at the top of the mounting base 2 via a bearing, a U-shaped operating platform 5 at the top of the connecting shaft 4, several slots 6 on the bottom exterior of the U-shaped operating platform 5, annular limiting blocks 7 on the inner wall of the U-shaped operating platform 5, annular limiting grooves 8 on the exterior of the mounting base 2, support plates 9 on both sides of the top of the U-shaped operating platform 5, and electric push rods 10 on one side of each of the two support plates 9. The extended end of 0 is provided with a clamping plate 11. A fixed seat 12 is provided on one side of the top center of the drive assembly 1. An installation groove 13 is opened in the top center of the fixed seat 12. Guide grooves 14 are opened on the four walls of the top of the installation groove 13. A positioning block 15 is provided between the two walls of the bottom of the installation groove 13. A lead screw 16 is provided on the top of the positioning block 15 through a bearing. A secondary bevel gear 17 is provided on the bottom of the lead screw 16. A threaded sleeve 18 is provided on the outside of the lead screw 16. Guide blocks 19 are provided on the four sides of the outside of the threaded sleeve 18. A connecting rod 20 is provided on one side of the fixed seat 12 through a bearing. A main bevel gear 21 is provided on one end of the connecting rod 20.
[0021] In this embodiment, as Figure 1 As shown, the drive assembly 1 includes a base 101, with support columns 102 at each of the four corners of the top of the base 101. A transverse drive mechanism body 103 is provided at the top of the four support columns 102, and a longitudinal drive mechanism body 104 is provided at the bottom of the transverse drive mechanism body 103. A telescopic rod 105 is provided at the bottom of the longitudinal drive mechanism body 104, and a non-contact welding head body 106 is provided at the extended end of the telescopic rod 105.
[0022] In this embodiment, as Figure 2 As shown, the central axis of the U-shaped operating table 5 is aligned with the central axis of the motor 3; this allows for the rotational adjustment of the direction angle of the automotive lamps according to the user's needs, greatly improving the convenience of adjusting the direction angle of the automotive lamps, thus meeting the requirements of non-contact welding devices for automotive lamps.
[0023] In this embodiment, as Figure 1As shown, the support plate 9 and the electric push rod 10 are symmetrical about the central axis of the mounting base 2 with respect to the clamping plate 11; this enables the fixing of automotive lamps of different sizes, thereby improving the stability of the lamps during fixing.
[0024] In this embodiment, as Figure 2 As shown, the internal dimensions of the annular limiting groove 8 and the external dimensions of the annular limiting block 7 are consistent; this ensures that the U-shaped operating table 5 moves in a single direction, preventing the U-shaped operating table 5 from shifting or tilting during rotation, thereby increasing the stability of the U-shaped operating table 5 during movement.
[0025] In this embodiment, as Figure 4 As shown, the guide groove 14 and the guide block 19 are provided with a sliding connection; this increases the stability of the threaded ferrule 18 during movement, thereby preventing the threaded ferrule 18 from rotating with the rotation of the lead screw 16 during movement.
[0026] In this embodiment, as Figure 3 As shown, the main bevel gear 21 and the secondary bevel gear 17 are meshed together; this enables the U-shaped operating table 5 to be quickly fixed after the direction angle is adjusted, solving the problem that automotive lamps are prone to displacement or rotation during welding, thereby greatly improving welding accuracy.
[0027] The method of use and advantages of this utility model: The working process of this non-contact welding device for automotive lamps is as follows:
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the base 101 is placed in the designated position, then the automotive lamp to be welded is placed on top of the U-shaped operating platform 5. Next, the controller activates two electric push rods 10, which in turn drive the clamping plate 11 to hold and fix the automotive lamp. Then, the controller activates the telescopic rod 105, causing the non-contact welding head body 106 to move downwards synchronously, enabling the non-contact welding head body 106 to perform welding on the automotive lamp. The lateral drive mechanism 103 adjusts the lateral movement of the non-contact welding head body 106, while the longitudinal drive mechanism 104 adjusts its longitudinal movement. This dual adjustment significantly improves the practicality of the welding device during use. When the direction and angle of the automotive lamp need to be adjusted, the controller activates the motor 3 to rotate. The motor 3 then drives the U-shaped operating platform 5 via the connecting shaft 4. The worktable 5 rotates in cooperation with the annular limiting block 7 and the annular limiting groove 8. At the same time, the U-shaped worktable 5 drives the automotive lamp to rotate synchronously, realizing the rotation adjustment of the direction angle of the automotive lamp according to the user's needs, greatly improving the convenience of adjusting the direction angle of the automotive lamp. Then, the connecting rod 20 is rotated by the knob. At this time, the connecting rod 20 drives the main bevel gear 21 to rotate. The main bevel gear 21 meshes and drives the secondary bevel gear 17 to rotate. The secondary bevel gear 17 drives the lead screw 16 to rotate. At this time, the lead screw 16 drives the threaded sleeve 18 to move upward with the cooperation of the guide groove 14 and the guide block 19 until the threaded sleeve 18 moves into the inside of the slot 6, so that the threaded sleeve 18 and the slot 6 form a snap-fit structure, realizing the quick fixation of the U-shaped worktable 5 after the direction angle is adjusted. This solves the problem that the automotive lamp is prone to displacement or rotation during welding, thereby greatly improving the welding accuracy and meeting the requirements of non-contact welding device for automotive lamps.
