[0017] Advantages of the above one or more technical solutions:

[0018] (1) First, drive the first pressing plate to move along the guide post by the first air cylinder, and use the copper block fixed below the first pressing plate to indirectly heat the hot riveting point of the lamp housing in a non-contact manner, baking and melting the hot riveting post of the lamp housing.

Detailed Embodiments

[0025] The following will describe the specific implementation manners of this embodiment with reference to the attached drawings Figures 1-3 .

[0026] The embodiment of the present application provides a segmented lamp hot riveting tooling. Referring to Figure 1 , a segmented lamp hot riveting tooling includes an upper bottom plate 1 and a lower bottom plate 2. Both the upper bottom plate 1 and the lower bottom plate 2 are made of rectangular steel plates, and the area of the upper bottom plate 1 is slightly smaller than that of the lower bottom plate 2. The upper bottom plate 1 and the lower bottom plate 2 are fixedly connected by four support columns 3, and the four support columns 3 are respectively located at the four corners of the upper bottom plate 1. A guide post 4 is further arranged between the upper bottom plate 1 and the lower bottom plate 2. Specifically, four guide posts 4 are arranged between the two side support columns 3, which are the first guide post 4-1, the second guide post 4-2, the third guide post 4-3 and the fourth guide post 4-4 respectively. The positions of the guide posts 4 on both sides correspond to each other, and limit blocks 6 are arranged on the guide posts 4 to limit the moving distance of the first pressing plate 9 and the second pressing plate 10

[0027] A first cylinder 7 and a second cylinder 8 are fixed on the upper bottom plate 1. There are two first cylinders 7 and two second cylinders 8 respectively. The straight lines where the two first cylinders 7 are located are parallel to the straight lines where the two second cylinders 8 are located; the first cylinder 7 adopts a SE50*180LB type cylinder; the second cylinder 8 adopts a SE50*260FA type cylinder. The strokes of the above two cylinders are convenient for operators to operate, and the provided pressure is suitable for lamp hot riveting. The output shaft of the first cylinder 7 is fixedly connected to the first pressing plate 9, and both ends of the first pressing plate 9 are sleeved on the first guide post 4-1 and the second guide post 4-2 through guide sleeves 5. A plurality of copper blocks 11 are further fixed below the first pressing plate 9. A heating rod (not shown in the attached drawings) is arranged inside the copper blocks 11, and the copper blocks 11 are quickly and evenly heated by the heating rod to reduce problems such as the deformation of the lamp housing caused by uneven heating of the copper blocks during the hot riveting process. Temperature sensing wires 12 are evenly arranged on the first pressing plate 9, and the temperature sensing wires 12 are used to detect the hot riveting temperature, so as to ensure that the temperature of the copper blocks 11 is always in the best state. In this embodiment, an insulating and heat insulating plate 13 is further arranged below each copper block. During the non-contact indirect heating process of the lamp housing 19, on the one hand, the insulating and heat insulating plate 13 can pre-press the melted hot riveting posts of the lamp housing 19, and on the other hand, it can prevent the other parts of the lamp housing 19 that do not need to be heated from being deformed by heat during the heating process, thereby improving the yield rate of the lamp housing 19 during the production process

[0028] The output shaft of the second cylinder 8 is connected to the second pressing plate 10; both ends of the second pressing plate 10 are sleeved on the third guide post 4-3 and the fourth guide post 4-4 through guide sleeves 5; a copper block 11 is also fixed below the second pressing plate 10, a heating rod is arranged inside the copper block 11, and temperature sensing wires 12 are evenly placed on the second pressing plate 10. The copper block is quickly and evenly heated through the temperature sensing wires 12 and the heating rod, and the heat riveting posts of the lamp housing 19 after being heated and fused by the copper block 11 passing through the first pressing plate 9 are directly pressed, so as to realize the heat riveting and fixing of the metal circuit board.

[0029] Furthermore, the first pressing plate 9 is also provided with a first limiting rod 14, and the first limiting rod 14 can cooperate with the second limiting rod 15 on the positioning plate 18 to further prevent the first pressing plate 9 from directly contacting the lamp housing 19 during the heating process.

[0030] In this embodiment, a slide rail 16 is also fixed on the lower bottom plate 2, the slide rail 6 is fixed to the lower bottom plate 2 by bolts, the slide rail 16 adopts a linear slide rail of model LSH35F2L1X400SOCN-M6, and the slide rail is driven to move by a servo motor 17. The servo motor 17 is also fixed to the lower bottom plate 2 by bolts. A positioning plate 18 is arranged above the slide rail 16, the lamp housing 19 is fixed on the positioning plate 18, and the lamp housing 19 is driven to move towards the first pressing plate 9 or the second pressing plate 10 by the movement of the slide rail 16. Furthermore, a second limiting rod 15 is also arranged on the positioning plate 18. On the one hand, the second limiting rod 15 can limit the first pressing plate 9, and on the other hand, it can realize the positioning of the lamp housing 19 and drive the lamp housing 19 to move through the linear slide rail.

[0031] The working principle of the segmented heat riveting tooling provided in this embodiment is as follows:

[0032] The lamp housing 19 is placed on the positioning plate 18, and the lamp housing is positioned by using the second limiting rod 15. The servo motor 17 drives the linear slide rail 16 to move downward below the first pressing plate 9. When it moves to the specified position, the first cylinder 7 drives the first pressing plate 9 to move downward. The position of the first pressing plate 9 is limited by the first limiting rod 14 on the first pressing plate 9, the second limiting rod 15 on the positioning plate 18, and the limiting block 6 on the guide post 4, so that the copper block 11 on the first pressing plate 9 and the lamp housing 19 on the positioning plate 18 are indirectly heated in a non-contact manner with a distance of 0.5 mm. When the heat riveting posts of the lamp housing 19 are heated and melted, the first cylinder 7 resets, and the linear slide rail 16 pushes the positioning plate 18 with the lamp housing fixed below to below the second cylinder 8. The second cylinder 8 drives the second pressing plate 10 to press the heat riveting posts that have been melted by roasting, so as to realize the heat riveting and fixing of the metal circuit board. Furthermore, by adopting segmented heat riveting in the lamp housing processing, problems such as material wire drawing in the integral heat riveting process of the lamp housing can be effectively solved.

[0033] Although the specific implementation manners of the present utility model have been described above in conjunction with the accompanying drawings, they are not limitations on the protection scope of the present utility model. Those skilled in the art should understand that various modifications or deformations that can be made without creative efforts on the basis of the technical solutions of the present utility model are still within the protection scope of the present utility model.
