During the downward movement, the hot riveting head 33 with high temperature heats the hot riveting piece 8 so that the hot riveting piece 8 is deformed by heat until the hot riveting head 33 contacts the supporting plane 10 on the outside of the supporting piece 9 and stops moving. At this time, the hot riveting piece 8 melts and deforms to fill the setting of the hot riveting head 33. Then, the hot riveting head 33 moves upward to the original position under the action of the driving device. At this time, the melted hot riveting piece 8 is cooled and fixed on the outside of the hot riveting hole 7.

[0037] Step 3: Take out the decorative frame 2 on the left mold cavity after the first hot riveting, install the remaining reflectors 3 in the installation channels 6 at the remaining positions 1, 3, 5, and 7, and then place the decorative frame 2 on the right mold cavity with the front end facing downward; at the same time, repeat step 1 and place a new decorative frame 2 to be processed on the left mold cavity; start the hot riveting equipment again, so that the hot riveting head 33 on the hot riveting equipment moves downward to work, perform the second hot riveting on the decorative frame 2 on the right mold cavity, and perform the first hot riveting on the decorative frame 2 on the left mold cavity;

[0038] Step 4: Take out the decorative frame assembly on the right mold cavity after two hot rivetings, and then repeat the above step 3 in sequence.

[0039] Furthermore, Figure 4 As shown, the hot riveting equipment in this embodiment includes a frame 11, a workbench 12 arranged on the frame 11, a base plate 13 detachably mounted on the workbench 12, a movable plate 14 located at the upper end of the base plate 13 and driven to move up and down by a driving device, positioning components 15 respectively mounted on the left and right sides of the base plate 13 for positioning the decorative frame 2, and a fixing member 16 mounted on the base plate 13 for fixing the decorative frame 2, and a hot riveting head 33 is mounted on the lower end surface of the movable plate 14; the movable plate 14 in this embodiment is driven to move up and down by a servo system; specifically, a servo cylinder 34 is fixedly connected to the upper end of the frame 11 in this embodiment, and the piston end of the servo cylinder 34 extends downward and is fixedly connected to the center position of the upper end of the movable plate 14, and then the servo cylinder 34 is used to drive the movable plate 14 to move up and down.

[0040] like Figure 4 and Fig. 9As shown, the hot riveting equipment in this embodiment also includes a fixed connecting member 25 detachably connected to the lower end surface of the movable plate 14, a support frame installed on the fixed connecting member 25, and a connecting rod 26 movably connected to the support frame up and down, the hot riveting head 33 is fixedly connected to the lower end of the connecting rod 26, the support frame includes a fixed plate 27 fixed to the fixed connecting member 25, support parts 28 respectively arranged at the upper and lower ends of the fixed plate 27, and a movable sleeve 29 installed on the inner side of the support part 28, the connecting rod 26 is movably connected to the inner side of the movable sleeve 29, a limiting wire part 30 fixedly connected to the outer side of the connecting rod 26 is provided between the upper and lower support parts 28, an extrusion spring 31 sleeved on the outer side of the connecting rod 26 is provided between the limiting wire part 30 and the upper end support part 28, and an anti-slip member for limiting the extreme position is provided on the outer side of the upper end of the connecting rod 26 32; During hot riveting, the hot riveting head 33 moves downward with the movable plate 14, gradually approaches the hot riveting piece 8 and is sleeved on the outside of the hot riveting piece 8 during the downward movement, and then the hot riveting head 33 moves downward and stops after contacting the support plane 10 at the lower end; in the present application, the hot riveting head 33 is fixedly connected to the connecting rod 26, and the connecting rod 26 can overcome the elastic force of the squeezing spring 31 when the hot riveting head 33 contacts the support plane 10 and moves upward relative to the fixed connecting piece 25 and the movable plate 14; and then when the hot riveting head 33 is working, the movable plate 14 continues to move downward a certain distance after the hot riveting head 33 contacts the support plane 10, thereby ensuring that there is a certain pre-pressure between the hot riveting head 33 and the support plane 10, and also eliminating the displacement error when the movable plate 14 moves downward, ensuring that the hot riveting head 33 can complete the hot riveting operation;

[0041] Among them, Figure 4 and Figure 5 As shown, the positioning assembly 15 in this embodiment includes a middle-end support member 15-1 installed on the base plate 13 and protruding upward, and a plurality of auxiliary support members 15-2 with limiting supports on the four sides of the decorative frame 2. The middle-end support member 15-1 is located in the installation cavity 1 and is arranged corresponding to the installation cavity 1. In this embodiment, the upper end of the middle-end support member 15-1 is provided with a limiting protrusion 37 arranged corresponding to the installation hole 4, and the auxiliary support member 15-2 is provided with a limiting structure with a limited position on the outside of the decorative frame 2; wherein, the limiting structure in this embodiment includes a bottom supporting surface 17 arranged on the auxiliary support member 15-2 and corresponding to the front end surface of the decorative frame 2, and a side limiting surface 18 connected to the bottom supporting surface 17 and arranged on the outside of the bottom supporting surface 17 for limiting the horizontal movement of the decorative frame 2.

[0042] Specifically, Figure 5 and Figure 8As shown, in order to accommodate the reflector 3 located on the decorative frame 2 during positioning support, the middle-end support member 15-1 in the positioning assembly 15 in this embodiment is provided with a receiving cavity 19 for accommodating the reflector 3 around it; because when the reflector 3 is hot-riveted, one of the hot-riveting members 8 arranged near the side of the mounting hole 4 is arranged at a position close to both the mounting hole 4 and the mounting channel 6, so that the decorative frame 2 part at the hot-riveting position lacks stable and effective support during hot-riveting, and the receiving cavity 19 corresponding to the hot-riveting position is provided with the reflector 3, so that it is impossible to provide a supporting component below the hot-riveting position; in order to solve the above problems, the middle-end support member 15-1 on the left mold cavity and the middle-end support member 15-1 on the right mold cavity have different structures in this embodiment;

[0043] Specifically, Figure 5 As shown, since the decorative frame 2 in the embodiment is first riveted through the left mold cavity and then placed on the right mold cavity for riveting, the decorative frame 2 on the left mold cavity only places the reflectors 3 at positions 2, 4, 6, and 8 during processing and only positions the reflectors 3 at these four positions for hot riveting, in this embodiment, the middle-end support member 15-1 on the left mold cavity is provided with a support stopper 24 installed in the left and right accommodating cavities 19, and the support stopper 24 is correspondingly arranged in the free installation channels 6 on the left and right sides and adjacent to the reflectors 3 in the left and right accommodating cavities 19. Specifically, in this embodiment

[0044] The support stopper 24 is horizontally protruded outward from the accommodating cavity 19, and the upper end surface of the support stopper 24 is flush with the upper end surface of the middle support member 15-1; when the decorative frame 2 is subjected to hot riveting, the decorative frame 2 is placed on the middle support member 15-1 from top to bottom, and when the decorative frame 2 moves downward, the support stopper 24 penetrates into the vacant installation channels 6 on the left and right sides of the decorative frame 2, and the upper end surface of the support stopper 24 contacts the bottom surface of the installation cavity 1 accordingly, thereby providing auxiliary support for the portion of the decorative frame 2 close to the hot riveting position, thereby avoiding pressing deformation at the hot riveting position, so as to ensure that during hot riveting, the support plane 10 and the hot riveting head 33 can fit closely, thereby ensuring the hot riveting quality of the decorative frame 2 and the reflector 3; at the same time, the support The front and rear side surfaces of the limiting member 24 are respectively limited in the installation channel 6, thereby further accurately positioning the decorative frame 2 to ensure that the rivet joint 33 can accurately correspond to the position of the hot riveted member 8 during riveting; further, in order to solve the auxiliary support problem of the hot riveting position in the above-mentioned front and rear directions, in this embodiment, a hot riveting auxiliary pressing portion 35 corresponding to the spare installation channel 6 of the decorative frame 2 is also provided on the front and rear side accommodating cavities 19 of the middle-end support member 15-1 of the left mold cavity. The hot riveting auxiliary pressing portion includes an auxiliary supporting surface 36 protruding from the accommodating cavity 19 and the upper end of which is flush with the upper end surface of the middle-end support member 15-1, and the upper end of the auxiliary supporting surface 36 is in contact with the bottom surface of the installation cavity 1 for support.

[0045] Correspondingly, such as Figure 8 As shown, in this embodiment, all reflectors 3 are arranged on the decorative frame 2 on the right mold cavity during processing, so the middle-end support member 15-1 on the right mold cavity in this embodiment only has an accommodating cavity 19, thereby avoiding interference between the reflector 3 and the middle-end support member 15-1.

[0046] Furthermore, Figure 7 As shown, before hot riveting the reflector 3, in order to avoid positional deviation of the reflector 3 and to avoid movement of the reflector 3 away from the installation position on the hot riveting side after hot riveting, a snap-fitting positioning groove 20 arranged parallel to the installation direction of the reflector 3 is provided at the front end of the side limit portion 3-4 in this embodiment, and a positioning protrusion 21 arranged corresponding to the snap-fitting positioning groove 20 is provided on the outer wall of the decorative frame 2; and then before hot riveting, the reflector 3 is first inserted into the installation channel 6 of the decorative frame 2 from back to front, and when the reflector 3 is almost completely inserted into the installation channel 6, the snap-fitting positioning groove 20 on the side limit portion 3-4 is snap-fitted correspondingly to the positioning protrusion 21 on the outer wall of the decorative frame 2, and at the same time, the hot rivet 8 passes through the hot rivet hole 7, so that the reflector 3 is accurately positioned before hot riveting.
