Description

Technical Field

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

[0002] Modern industrial technology is driving the rapid development of the new energy vehicle industry, and headlights are the soul of a car. Assembly is a crucial step in the lighting process, requiring precise installation of each component into the lamp housing, followed by testing and commissioning. With the continuous development of the new energy vehicle industry, a wide variety of headlights have emerged to meet the diverse needs of these vehicles. In order to ensure the lighting quality of existing headlights, a certain number of reflectors are usually designed. 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 that the normal directions are basically consistent for visual inspection, so the traditional fixed CCD camera cannot simultaneously inspect multiple reflectors with different normal directions. Due to the large number of reflectors in the existing headlight frame group, the structural design is relatively complex and it is not convenient for hot riveting welding of the reflectors, which usually leads to poor welding, overflow, loose welding, and unsightly workmanship. The headlight frame group that has passed the inspection needs to be moved to the hot riveting equipment for the next step of hot riveting. 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 becoming increasingly 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

[0004] The present invention aims to solve the problems existing in the above-mentioned prior art and provides a headlight frame group with multiple fixed points, a processing method and a processing equipment thereof, so that the headlight frame group is more solid, the lighting quality is better and the hot riveting processing of the frame group is convenient; at the same time, it has a visual inspection function and a hot riveting function that can detect multiple reflectors with different normal directions. After the headlight frame group passes the visual inspection, it moves a shorter distance and completes the hot riveting fixation.

[0005] The present invention solves its technical problem by adopting a technical solution: this multi-fixing point vehicle lamp decorative frame group includes a decorative frame body and a reflector installed on the decorative frame, the central area of the decorative frame body is concave to form a mounting cavity, and the reflector is installed in the mounting cavity; a mounting hole for mounting the reflector is provided on the inner side wall of the mounting cavity, and the mounting hole passes through the side wall and bottom wall of the mounting cavity to the back side of the mounting cavity; the reflector includes a reflective body inserted into the mounting cavity from the back side of the decorative frame body and an abutment portion arranged around the back edge of the reflective body, the abutment portion abutting around the back side of the mounting hole, the abutment portion includes a bottom limiting portion abutting against the bottom plate of the mounting cavity and a side limiting portion abutting against the side plates of the mounting cavity; a hot rivet is provided on the back side of the mounting cavity bottom plate, the hot rivet hole for the hot rivet to pass through is opened on the bottom limiting portion, the hot rivet hole is provided with a support seat protruding from the bottom limiting portion, and the support seat is provided with a support plane arranged perpendicular to the hot rivet.

[0006] The method for processing a multi-fixed-point vehicle lamp frame assembly comprises the following steps:

DETAILED DESCRIPTION

[0034] The following combination Figures 1-12 The present invention will be further described:

[0035] Combine Figure 1 、 Figure 2 and Figure 3 This embodiment discloses a headlight bezel assembly with multiple fixing points, comprising a bezel body 1. The front of the bezel body 1 is recessed to form a mounting cavity 11. The mounting cavity 11 has a square cross-section, comprising a bottom wall and four side walls, each of which is mounted with a pair of reflectors 2. Each inner sidewall of the mounting cavity 11 is provided with a pair of spaced mounting holes 12 for mounting the reflectors 2. The mounting holes 12 extend through the side and bottom walls of the mounting cavity 11 to the back of the cavity 11. Due to design requirements, the bezel body 1 is tilted at the outer edge of the mounting cavity 11, allowing the headlight bezel assembly to fit snugly onto the vehicle body.

[0036] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4The reflector 2 includes a reflective body 21 inserted into and mounted on the mounting hole 12, and an abutment portion 22 provided around the back edge of the reflective body 21. The front 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 inward toward the side away from the side wall of the mounting cavity 11. The abutment portion 22 abuts against the edge of the back of the mounting hole 12, thereby limiting the position of the reflective body 21. The abutment portion 22 includes a bottom limiting portion 221 abutting against the back of the bottom wall of the mounting cavity 11 and a side limiting portion 222 abutting against the back 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.

[0037] Combine Figure 2 、 Figure 4 and Figure 5 To securely connect the reflector 2 to the decorative frame body 1, several heat-riveted components 13 are integrally injection-molded on the backside of the bottom wall of the mounting cavity 11. In this embodiment, eight reflectors 2 are mounted within the decorative frame body 1, each connected via two heat-riveted components 13. Therefore, sixteen heat-riveted components 13 are spaced apart on the backside of the bottom wall of the mounting cavity 11. Two heat-riveted holes 223 are defined on the bottom stop 221 of each reflector 2, corresponding to the heat-riveted components 13. The heat-riveted holes 223 engage with the heat-riveted components 13. A support base 224 is provided on the bottom stop 221, corresponding to the heat-riveted holes 223. The support base 224 is provided with a support plane 225 perpendicular to the heat-riveted components 13. After the heat-riveted components 13 are heated and melted, they cover the support plane 225. After the heat-riveted components 13 cool, they tightly engage with the support plane 225, securing the reflector 2 to the decorative frame body 1. The sixteen hot rivets 13 are all fixed vertically to the back side of the bottom wall of the installation cavity 11, which is conducive to batch hot riveting of the hot rivets 13 at multiple points, thereby improving work efficiency; since the hot rivet head 711 is sleeved on the outside of the hot rivet 13 and moves linearly during hot riveting, a support plane 225 perpendicular to the hot rivet 13 is provided in the present application, so that the hot rivet head 711 can be fully contacted and limited with the support plane 225 during hot riveting, thereby preventing the hot rivet 13 from overflowing from the hot rivet head 711 after melting through the hot rivet head 711 to form overflow, thereby ensuring the hot riveting quality of the decorative frame group.

[0038] Combine Figure 2 、 Figure 4 and Figure 6 The side limiter 222 has a positioning groove 226 at one end near the front of the decorative frame body 1. The decorative frame body 1 has a positioning bump 14 at a location corresponding to the positioning groove 226. The positioning bump 14 engages with the positioning groove 226 for positioning. The bottom limiter 221 has two heat rivets 13 for positioning, and the side limiter 222 has a positioning bump 14 for positioning. This ensures that each reflector 2 is spatially positioned at three positioning points, improving the installation accuracy of the reflector 2.

[0039] Combine Figure 7 and Figure 8 This embodiment also discloses a servo-type high-frequency hot riveting device with a visual inspection function. The device comprises a frame 3, a work platform 31 fixed to the center of the frame 3, a first clamping device 4 and a second clamping device 5 mounted on the work platform 31, a visual optometry system 6 positioned in coordination with the first clamping device 4, and a high-frequency hot riveting system 7 positioned in coordination with the second clamping device 5. A light-proof cabinet 33 for mounting the visual optometry system 6 is located at the bottom of the frame 3, and the high-frequency hot riveting system 7 is mounted on the top of the frame 3. In this embodiment, the servo-type high-frequency hot riveting device has two workstations, each equipped with a set of first clamping devices 4, second clamping devices 5, visual optometry system 6, and high-frequency hot riveting system 7. The end away from the operator is the front end, and the end closer to the operator is the rear end. Specifically, the high-frequency hot riveting system 7 is located at the front end, while the visual optometry system 6 is located at the rear end. The operator first places the headlight trim assembly into the visual optometry system 6 at the rear end for inspection. If the inspection passes, the headlight trim assembly is then placed into the high-frequency hot riveting system 7 at the front end for hot riveting. The headlight frame assembly requires multiple working steps during 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.

[0040] Combine Figure 8 and Figure 9 The visual optometry system 6 includes an industrial robot 61 fixedly mounted in a dark cabinet 33 and an inspection camera 62 fixed to the movable end of the industrial robot 61. The inspection camera 62 is a CCD camera. Because the headlight bezel assembly contains four pairs of reflectors 2, and the normal orientation of the reflection area 211 of each pair of reflectors 2 is different, the fixed inspection camera 62 cannot fully cover the light reflected by the reflectors 2, and therefore cannot meet the optometry test requirements. This embodiment uses the industrial robot 61 to drive the inspection camera 62 to perform optometry testing at multiple angles, normal directions, and distances, accurately detecting good and bad (NG) conditions in both dynamic and static operation of the headlight bezel assembly.

[0041] The first clamping device 4 includes a first platform 41 fixed to the work platform 31, a first support assembly 42 fixed to the first platform 41, and a first pressing assembly 43. A rectangular optometry aperture 411 is defined in the center of the first platform 41. A light-transmitting plate 44 is positioned below the first platform 41 and fixed to the frame 3. The decorative frame body 1 is placed face-down on the first support assembly 42. The first pressing assembly 43 cooperates with the first support assembly 42 to secure the decorative frame body 1.

[0042] The first support assembly 42 includes a first front support member 421 and a first rear support member 422, spaced apart from each other on the first platform 41. The first front support member 421 defines a first front limiting groove 4211 for supporting and limiting the front end of the decorative frame body 1, while the first rear support member 422 defines a first rear limiting groove 4221 for supporting and limiting the rear end of the decorative frame body 1. Because the front face of the decorative frame body 1 is inclined, the first front support member 421 is higher than the first rear support member 422. This allows the mounting cavity 11 to face downward vertically when the decorative frame body 1 is placed upside down on the first front support member 421 and the first rear support member 422, with the opening of the mounting cavity 11 aligned with the optometry aperture 411.

[0043] In this embodiment, two first front support members 421 are provided and are arranged in front of the optometry hole 411, and two first rear support members 422 are provided and are arranged behind the optometry hole 411; the two first front support members 421 and the two first rear support members 422 are respectively arranged at the four corners of the optometry hole 411, and the two corner limits at the front end of the decorative frame body 1 are located in the first front limit groove 4211, and the two corner limits at the rear end of the decorative frame body 1 are located in the first rear limit groove 4221.

[0044] refer to Figure 10 The first pressing assembly 43 includes two first pressing members 431 fixed on the first platform 41 at intervals, and the two first pressing members 431 are respectively fixed on the left and right sides of the optometry hole 411. The first pressing member 431 includes a first pressing cylinder 81 vertically fixed on the first platform 41, a horizontal rod 82 with one end hinged to the movable end of the first pressing cylinder 81, a connecting seat 83 fixed to the top end surface of the first pressing cylinder 81, a connecting member 84 hinged to the top of the connecting seat 83, and a buffer block 85 fixed to the end of the horizontal rod 82. The end of the connecting member 84 away from the connecting seat 83 is hinged to the horizontal rod 82, and the buffer block 85 is fixed below the end of the horizontal rod 82 away from the first pressing cylinder 81. The connecting seat 83 is spaced apart from the telescopic rod of the first pressing cylinder 81, and the end of the connecting member 84 hinged to the horizontal rod 82 is spaced apart from the telescopic rod of the first pressing cylinder 81.

[0045] Combine Figure 11 and Figure 12The high-frequency hot riveting system 7 includes a hot riveting welding device 71 and a servo drive device 72 for driving the hot riveting welding device 71 to move up and down. The hot riveting welding device 71 includes multiple hot riveting heads 711. The multiple hot riveting heads 711 can simultaneously perform hot riveting welding on multiple hot riveted parts 13, thereby improving the work efficiency of hot riveting welding. The servo drive device 72 includes a mobile platform 721 that can move up and down and is equipped with the hot riveting head 711, and a servo electric cylinder 722 for driving the mobile platform 721 to move up and down. The servo electric cylinder 722 is vertically fixed to the top of the frame 3, and the movable end of the servo electric cylinder 722 faces downward and is fixedly connected to the mobile platform 721. The servo electric cylinder 722 can accurately control the welding position of the hot riveting head 711. The hot riveting welding point adopts a high-frequency control output module to control the welding process parameters, thereby ensuring the quality of welding and work efficiency.

[0046] In order to make the up and down movement of the mobile platform 721 more stable, sliding kits 723 are installed at the four corners of the mobile platform 721. Four sliding rods 32 are vertically fixed to the four sliding kits 723 of the frame 3 corresponding to the four sliding kits 723. The sliding kits 723 are sleeved on the sliding rods 32, and the sliding kits 723 and the sliding rods 32 slide together.

[0047] The second clamping device 5 includes a second platform 51 fixed on the working platform 31, a second supporting assembly 52 and a second pressing assembly 53 fixed on the second platform 51, and the decorative frame body 1 is placed face down on the second supporting assembly 52, and the second supporting assembly 52 and the second pressing assembly 53 cooperate with each other to clamp and fix the decorative frame body 1. The second support assembly 52 includes a middle support member 521 fixed on the second platform 51, a second front support member 522 arranged in front of the middle support member 521, and a second rear support member 523 arranged behind the middle support member 521. When the decorative frame body 1 is upside down on the middle support member 521, the middle support member 521 is plugged into the installation cavity 11, and a receiving groove 5211 for accommodating the reflector 2 is provided at the side of the middle support member 521. The second front support member 522 is provided with a second front limiting groove 5221 for supporting the front end of the limiting decorative frame body 1, and the second rear support member 523 is provided with a second rear limiting groove 5231 for supporting the rear end of the limiting decorative frame body 1. In this embodiment, two second front supports 522 and two second rear supports 523 are provided. The two second front supports 522 are fixed at intervals to the front end of the middle support 521, and the two second rear supports 523 are fixed at intervals to the rear end of the middle support 521. The two corner limits at the front end of the decorative frame body 1 are located in the two second front limit grooves 5221, and the two corner limits at the rear end of the decorative frame body 1 are located in the two second rear limit grooves 5231. The second front supports 522 have a substantially identical structure to the first front supports 421, and the second rear supports 523 have a substantially identical structure to the first rear supports 422.

[0048] The second pressing assembly 53 includes two second pressing members 531 fixed at intervals on the second platform 51. The two second pressing members 531 are respectively fixed on the left and right sides of the middle support member 521. The second pressing members 531 have basically the same structure as the first pressing member 431 and are not described in detail.

[0049] In order to allow the hot riveting head 711 to perform hot riveting welding accurately and stably, a vertically arranged positioning sleeve 92 is provided at each of the four corners of the bottom surface of the movable platform 721 , and a positioning rod 91 is vertically fixed at the position of the second platform 51 corresponding to the positioning sleeve 92 .

[0050] This embodiment further discloses a method for processing a vehicle lamp frame assembly with multiple fixed points based on the above-mentioned structure and the servo high-frequency hot riveting device with a visual inspection function, including the following steps:

[0051] Step 1: Place the decorative frame body 1 with the front side facing downward, and then insert the reflector body 21 into the mounting hole 12, so that the bottom stopper 221 abuts against the back of the bottom wall of the mounting cavity 11, the side stopper 222 abuts against the back of the side wall of the mounting cavity 11, and the heat rivet hole 223 on the bottom stopper 221 is sleeved on the heat rivet 13 on the bottom plate of the mounting cavity 11, and the positioning groove 226 of the side stopper 222 is engaged with the positioning protrusion 14;

[0052] Step 2: Start the servo high-frequency hot riveting equipment with a visual inspection function, place the decorative frame body 1 with the reflector 2 installed face down, and place the four corners of the decorative frame body 1 on the first front support 421 and the first rear support 422. Start the first pressing member 431, and the piston rod of the pressing cylinder 81 extends, so that the buffer block 85 applies a downward force to the decorative frame body 1, thereby clamping the decorative frame body 1. Start the visual optometry system 6, and the inspection camera 62, under the control of the industrial robot 61, performs multi-angle, multi-normal, and multi-distance visual inspection on the reflector 2. If the inspection is qualified, proceed to the next step; if the inspection fails, replace the reflector 2 and repeat step 2.

[0053] Step 3: Activate the first pressing member 431 again, the piston rod of the pressing cylinder 81 contracts, the buffer block 85 rises, and the qualified headlight frame assembly is removed from the first front support member 421 and the first rear support member 422, while keeping the headlight frame body 1 facing downward. Then, move the headlight frame body 1 steadily onto the middle support member 521, and activate the second pressing member 531 to clamp and fix the headlight frame body 1.

[0054] Step 4: Start the high-frequency hot riveting system 7. The hot riveting head 711 of the hot riveting welding device 71 moves toward the hot riveted part 13 under the drive of the servo drive device 72. The hot riveting head 711 on the hot riveting welding device 71 moves downward and contacts the hot riveted part 13. The high-temperature hot riveting head 711 causes the hot riveted part 13 to be deformed by heat, and the hot riveting head 711 continues to move downward until the hot riveting head 711 contacts the supporting plane 225 on the support seat 224 and stops moving.
