Description

Technical Field

[0001] The present invention relates to the technical field of new energy automobile lamps, and in particular to a processing method and processing equipment for a lamp decorative frame group with multiple fixed points. Background Art

[0002] Modern industrial technology leads to the rapid development of the new energy vehicle industry, and car lights are the soul of the car. Assembly is an important link in the process of car lights. Each component needs to be accurately installed in the car light housing, and then tested and debugged. With the continuous development of the new energy vehicle industry, in order to meet the different needs of new energy vehicles, various types of car lights have emerged. In order to ensure the lighting quality, existing headlights usually need to design a certain number of reflectors. At the same time, in order to make the headlights beautiful, a corresponding number of reflectors need to be newly arranged and designed. When multiple reflectors are provided and the normal directions of the reflectors are different, the traditional fixed CCD camera requires the normal directions to be basically consistent for visual inspection, so the traditional fixed CCD camera cannot simultaneously inspect multiple reflectors with different normal directions. In existing headlight frame groups, due to the large number of reflectors, the structural design is relatively complex and it is not convenient for hot riveting welding of reflectors, which usually leads to factors such as poor welding, overflow, loose welding, and unsightly workmanship. The headlight frame groups that have passed the inspection need to be moved to the hot riveting equipment for the next step of hot riveting fixation. If the hot riveting equipment is too far away, the raised light guide may be displaced when the worker moves the headlight frame group, which may result in the headlight frame group passing the visual inspection but failing after hot riveting.

[0003] Therefore, the requirements for the design and processing of car lights are getting higher and higher. The current structural design and simple clip-on or screw connection cannot meet the requirements for stable assembly of car lights. There are deficiencies in the design, processing, quality inspection and other processing aspects of car lights. Summary of the invention

DETAILED DESCRIPTION

[0019] Combine the following Figure 1-Figure 12The present invention will be further described: Combination Figure 1 , Figure 2 and Figure 3 This embodiment discloses a headlight trim assembly with multiple fixing points, including a trim body 1, the front of the trim body 1 is concave to form a mounting cavity 11, the cross section of the mounting cavity 11 is square, so that the mounting cavity 11 has a bottom wall and four side walls, and a pair of reflectors 2 are mounted on each side wall. A pair of mounting holes 12 arranged at intervals for mounting the reflectors 2 are opened on each inner side wall of the mounting cavity 11, and the mounting holes 12 pass through the side walls and bottom walls of the mounting cavity 11 to the back of the mounting cavity 11. Due to design requirements, the trim body 1 at the outer edge area of ​​the mounting cavity 11 is tilted, so that the headlight trim assembly fits the vehicle body.

[0020] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 The reflector 2 includes a reflective body 21 inserted and installed on the mounting hole 12 and an abutment portion 22 arranged around the edge of the back side of the reflective body 21. The front side of the reflective body 21 inserted into the mounting cavity 11 is a reflective area 211. The side of the reflective area 211 close to the side wall of the mounting cavity 11 is inclined inwardly arranged toward the side away from the side wall of the mounting cavity 11. The abutment portion 22 abuts against the edge of the back side of the mounting hole 12, thereby limiting the reflective body 21. The abutment portion 22 includes a bottom limiting portion 221 abutting against the back side of the bottom wall of the mounting cavity 11 and a side limiting portion 222 abutting against the back side of the side wall of the mounting cavity 11. The reflective body 21, the bottom limiting portion 221 and the side limiting portion 222 are integrally injection molded.

[0021] Combination Figure 2 , Figure 4 and Figure 5In order to fix the reflector 2 to the decorative frame body 1, a plurality of heat rivets 13 are integrally injection molded on the back of the bottom wall of the installation cavity 11. In this embodiment, eight reflectors 2 are installed in the decorative frame body 1, and each reflector 2 is connected by two heat rivets 13. Therefore, there are sixteen heat rivets 13 arranged at intervals on the back of the bottom wall of the installation cavity 11. Two heat rivet holes 223 are provided at the bottom limit portion 221 of each reflector 2 corresponding to the heat rivet 13, and the heat rivet holes 223 are plugged and matched with the heat rivet 13. A support seat 224 is provided at the bottom limit portion 221 corresponding to the heat rivet hole 223, and a support plane 225 perpendicular to the heat rivet 13 is provided on the support seat 224. The heat rivet 13 is heated and melted and covered on the support plane 225. When the heat rivet 13 is cooled, the heat rivet 13 is tightly matched with the support plane 225, so that the reflector 2 is fixed on the decorative frame body 1. The sixteen hot riveted parts 13 are all vertically fixed to the back side of the bottom wall of the installation cavity 11, which is conducive to batch hot riveting of the hot riveted parts 13 at multiple points, thereby improving work efficiency; since the hot riveting head 711 is sleeved on the outside of the hot riveted parts 13 and moves linearly during hot riveting, a supporting plane 225 perpendicular to the hot riveted parts 13 is provided in the present application, so that the hot riveting head 711 can be completely contacted and limited with the supporting plane 225 during hot riveting, thereby preventing the hot riveted parts 13 from overflowing from the hot riveting head 711 after being melted by the hot riveting head 711 to form overflow, thereby ensuring the hot riveting quality of the decorative frame group.

[0022] Combination Figure 2 , Figure 4 and Figure 6 The side limiter 222 has a positioning groove 226 at one end close to the front of the decorative frame body 1, and the decorative frame body 1 has a positioning convex point 14 at the position corresponding to the positioning groove 226, and the positioning convex point 14 is inserted and positioned with the positioning groove 226. The bottom limiter 221 has two hot rivets 13 for positioning, and the side limiter 222 has a positioning convex point 14 for positioning, so that each reflector 2 is spatially positioned through three positioning points, thereby improving the installation accuracy of the reflector 2.

[0023] Combination Figure 7 and Figure 8The present embodiment also discloses a servo high-frequency hot riveting device with a visual inspection function, comprising a frame 3, a working platform 31 fixed to the middle of the frame 3, a first clamping device 4 and a second clamping device 5 arranged on the working platform 31, a visual optometry system 6 arranged in coordination with the first clamping device 4, and a high-frequency hot riveting system 7 arranged in coordination with the second clamping device 5. A dark cabinet 33 which is opaque and used for installing the visual optometry system 6 is provided at the bottom of the frame 3, and the high-frequency hot riveting system 7 is installed at the top of the frame 3. In the present embodiment, the servo high-frequency hot riveting device is provided with two workstations, each of which is provided with a set of the first clamping device 4, the second clamping device 5, the visual optometry system 6 and the high-frequency hot riveting system 7. The end away from the operator is the front end, and the end close to the operator is the rear end, that is, the high-frequency hot riveting system 7 is arranged at the front end, and the visual optometry system 6 is arranged at the rear end. The operator first puts the headlight frame group into the visual optometry system 6 at the rear end for inspection, and then puts the headlight frame group into the high-frequency hot riveting system 7 at the front end for hot riveting after passing the inspection. The headlight frame assembly requires multiple working steps in the production process. The servo high-frequency hot riveting equipment effectively solves the optometry inspection and hot riveting welding at the same workstation, thereby improving production efficiency. Since the headlight frame assembly needs to undergo optometry inspection before hot riveting welding, the servo high-frequency hot riveting equipment shortens the spatial distance between the two processes, thereby reducing the movement and dislocation of the reflector 2 when the headlight frame assembly moves from the optometry inspection process to the hot riveting welding process, thereby improving the production quality of the headlight frame assembly.
