[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] An automotive lamp pin welding device includes a device body 1 and a mold 2. The device body 1 includes a base 101, a three-axis mobile platform 102, and a welding head 103. The top of the base 101 is fixedly connected to a base frame 3. A placement table 4 is provided on the top of the base frame 3. The rear end surface of the placement table 4 is fixedly connected to a limit plate 14 that abuts the mold 2 via a horizontal bar 7. The middle of the placement table 4 is integrated with two sets of positioning plates 12 and a drive assembly for driving the two sets of positioning plates 12 to move relative to each other.

[0025] The lamp and the pin are combined in the mold 2, and then the mold 2 is transferred as a whole to the placement table 4, and the outer wall of the mold 2 is abutted against the limit plate 14, and then the transmission rod 15 is rotated. The outer wall of the transmission rod 15 is screwed with the two sets of screw sleeves 16 through two sets of opposite thread grooves. The two sets of screw sleeves 16 drive the two sets of positioning plates 12 to move relative to each other, thereby realizing the centering positioning of the mold 2. Finally, the lamp and the pin are welded by the cooperation of the three-axis mobile platform 102 and the welding head 103. In this way, the convenience of disassembly and assembly of the mold 2 is ensured, and the clamping and positioning of molds 2 of different sizes can be adapted, thereby improving the applicability of the automobile lamp pin welding equipment.

[0026] It should be noted that the mold 2 here refers to the existing technology, so the specific structure of the mold 2 and the assembly process of the lamp and the pins will not be described in detail here.

[0027] Specifically, such as Figure 2 and Figure 4As shown, the base frame 3 is rotatably connected to the front side of the placement table 4 by a rotating shaft, and the base frame 3 is fixedly connected to one side of the horizontal end of the placement table 4 by a connecting part, and a collecting drawer 5 that abuts the front end surface of the base frame 3 is placed on the top of the base 101. The connecting part includes a strap 10 fixedly connected to the placement table 4, and the strap 10 is fixedly connected to the base frame 3 through a locking rod 11. The locking rod 11 is rotated to separate the base frame 3, and then the placement table 4 is lifted up with the locking rod 11 as a handle. The placement table 4 will deflect with the rotating shaft as the axis. As the placement table 4 deflects, the debris on the placement table 4 will roll down under the action of its own gravity until it falls into the collecting drawer 5, thereby preventing the debris generated during welding from contaminating the working area while ensuring the convenience of debris cleaning.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the rear end face of the collecting drawer 5 abuts against the front end face of the base frame 3, and the front end face of the collecting drawer 5 is overlapped with a bracket 13 fixedly connected to the base 101, which not only limits the position of the collecting drawer 5, but also does not affect the rapid separation of the collecting drawer 5. The rear end face of the placing table 4 is fixedly connected to a jacket 8 slidably connected to the horizontal bar 7, and the top of the jacket 8 is screwed with a positioning rod 9, and the open end of the positioning rod 9 abuts against the top of the horizontal bar 7, so that the position of the limit plate 14 can be adjusted according to needs. The driving assembly includes a liner 6 fixedly connected to the placing table 4, and the inner surface wall of the liner 6 is rotatably connected to the transmission rod 15. The outer wall of the transmission rod 15 is screwed with two groups of screw sleeves 16 through two groups of opposite thread grooves. The two groups of screw sleeves 16 are fixedly connected to the two groups of positioning plates 12 respectively. When the transmission rod 15 is rotated, the outer wall of the transmission rod 15 is screwed with the two groups of screw sleeves 16 through two groups of opposite thread grooves, and the two groups of screw sleeves 16 drive the two groups of positioning plates 12 to move relative to each other.

[0029] Working principle: Combine the lamp and the pin in the mold 2, then transfer the mold 2 as a whole to the placement table 4, and make the outer wall of the mold 2 abut against the limit plate 14, then rotate the transmission rod 15, and the outer wall of the transmission rod 15 is screwed with the two sets of screw sleeves 16 through two sets of opposite thread grooves. The two sets of screw sleeves 16 drive the two sets of positioning plates 12 to move relative to each other, thereby realizing the center positioning of the mold 2. Finally, the three-axis mobile platform 102 and the welding head 103 are used to realize the welding of the lamp and the pin, thereby ensuring the convenience of disassembly and assembly of the mold 2. At the same time, it can adapt to the clamping and positioning of molds 2 of different sizes, thereby improving the applicability of the automobile lamp pin welding equipment. The locking rod 11 is rotated to separate the base frame 3, and then the locking rod 11 is used as a handle to lift the placement table 4. The placement table 4 will deflect with the rotation axis as the axis. As the placement table 4 deflects, the debris on the placement table 4 will roll down under the action of its own gravity until it falls into the collection drawer 5, thereby preventing the debris generated during the welding process from contaminating the working area and ensuring the convenience of debris cleaning.
