[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, an embodiment of this application provides a hot air welding mechanism for car logos, including a workbench 1. The workbench 1 is provided with a feeding mechanism 2, a detection mechanism 3, a hot air mechanism 4 and a riveting mechanism 5. The riveting mechanism 5 is located between the detection mechanism 3 and the hot air mechanism 4, and the feeding mechanism 2 is located on one side of the detection mechanism 3, the riveting mechanism 5 and the hot air mechanism 4.

[0023] like Figure 2 As shown, the feeding mechanism 2 includes a horizontal drive mechanism 21, a base plate 22, and a contour jig 23 for placing the airbag cover. The horizontal drive mechanism 21 is mounted on the workbench 1, and the drive end of the horizontal drive mechanism 21 is connected to the base plate 22. The base plate 22 and the bottom end of the workbench 1 are slidably engaged by a sliding component 24. The contour jig 23 is mounted on the base plate 22. The horizontal drive mechanism 21 is used to drive the base plate 22 to move the contour jig 23 to one side of the detection mechanism 3, the riveting mechanism 5, or the hot air mechanism 4.

[0024] Specifically, the logo is first assembled onto the airbag cover using plastic pins, and then placed on the conforming fixture 23 of the feeding mechanism 2. The inspection mechanism 3 takes photos to inspect the assembly position of the airbag cover and plastic pins on the conforming fixture 23. After the inspection is qualified, the horizontal drive mechanism 21 drives the base plate 22 to move the conforming fixture 23 to one side of the hot air mechanism 4. The first lifting drive mechanism 42 of the hot air mechanism 4 drives the mounting base 43 to move the hot air gun 44 and the conforming air outlet 45 downward, so that the conforming air outlet 45 positions the plastic pin. The air outlet of the hot air gun 44 blows air to heat melt the plastic pin. After the heat melting is completed, the horizontal drive mechanism 21 drives the base plate 22 to move the airbag cover to one side of the riveting mechanism 5. The second lifting drive mechanism 52 of the riveting mechanism 5 drives the riveting head 54 downward to weld the plastic pin onto the airbag cover, thus completing the welding work of the logo and the airbag cover. Finally, the horizontal drive mechanism 21 drives the base plate 22 to move the welded airbag cover to one side of the inspection mechanism 3. The inspection mechanism 3 takes pictures of the welded airbag cover for inspection. After the inspection is completed, the airbag cover is manually unloaded.

[0025] In the above structure, the feeding mechanism 2, inspection mechanism 3, hot air mechanism 4, and riveting mechanism 5 work together to realize the feeding, inspection, and welding operations of the airbag cover and the emblem. The riveting mechanism 5 is located between the hot air mechanism 4 and the inspection mechanism 3, so that the hot air mechanism 4 is located at the far side, which improves the safety of the welding equipment. This hot air welding mechanism for automobile emblems is not only simple in structure and easy to operate, but also improves welding quality and efficiency, while meeting safety requirements.

[0026] like Figure 2 and Figure 3As shown, in one embodiment, the hot air mechanism 4 of the car logo hot air welding mechanism includes a first support base 41, a first lifting drive mechanism 42, a mounting base 43, a hot air gun 44, and a contour air vent 45. The first support base 41 is mounted on the workbench 1, the first lifting drive mechanism 42 is mounted on the first support base 41, and the drive end of the first lifting drive mechanism 42 is connected to the mounting base 43. The mounting base 43 and the first support base 41 slide vertically together. The hot air gun 44 and the contour air vent 45 are mounted on the mounting base 43. The contour air vent 45 is located on one side of the air outlet pipe of the hot air gun 44. The first lifting drive mechanism 42 drives the mounting base 43 to move the hot air gun 44 and the contour air vent 45 downward. The contour air vent 45 and the hot air gun 44 perform a hot melting operation on the upper half of the plastic pin. When the feeding mechanism 2 drives the contour jig 23 to move the airbag cover below the hot air gun 44, the first lifting drive mechanism 42 drives the mounting base 43 to move the hot air gun 44 and the contour air outlet 45 downwards. The contour air outlet 45 and the hot air gun 44 work together to heat and melt the upper half of the plastic pin. A temperature sensing mechanism for detecting the temperature is provided at the air outlet of the hot air gun (44). The temperature sensing mechanism monitors the temperature of the air outlet in real time and feeds it back to the control system for adjustment to ensure the constant temperature of the hot melt. The temperature sensing mechanism is a temperature sensor, etc. This setting not only realizes the hot melt operation, but also controls the temperature, improving its applicability.

[0027] like Figure 2 and Figure 3 As shown, in one embodiment, the first lifting drive mechanism 42 of the car logo hot air welding mechanism includes a second motor 421 and a second lead screw transmission mechanism 422. The second lead screw transmission mechanism 422 includes a second lead screw and a second nut seat. The second nut seat is threadedly connected to the second lead screw and is connected to the mounting base 43. The drive end of the second motor 421 is connected to the second lead screw, and the second motor 421 drives the second lead screw to rotate. The second nut seat drives the mounting base 43 to move up and down along the second lead screw. This arrangement facilitates the driving of the mounting base 43 to move the hot air gun 44 and the contour air vent 45 up and down, improving the stability during the hot melt operation.

[0028] like Figure 2 and Figure 3 As shown, in one embodiment, the first support 41 and mounting base 43 of the car logo hot air welding mechanism are provided with a plurality of fans 46 for heat dissipation. The fans 46 are mounted on both sides of the hot air gun 44 and dissipate heat from the hot air gun 44 when it is performing hot melting treatment. This arrangement not only facilitates heat dissipation from the hot air gun 44, but also facilitates heat dissipation from the unmelted parts of the product.

[0029] like Figure 2As shown, in one embodiment, the riveting mechanism 5 of the hot air welding mechanism for the car emblem includes a second support base 51, a second lifting drive mechanism 52, a fixed base 53, and a riveting head 54. The second support base 51 is mounted on the workbench 1. The drive end of the second lifting drive mechanism 52 is connected to the fixed base 53. The fixed base 53 and the second support base 51 slide vertically together. The riveting head 54 is mounted at the bottom of the fixed base 53. The second lifting drive mechanism 52 drives the fixed base 53 to move the riveting head 54 downwards, and the riveting head 54 performs a riveting operation on the plastic pin after the airbag cover has been hot-melted. The structure of the second lifting mechanism is the same as that of the first lifting drive mechanism 42, and can also be adjusted according to requirements. When the feeding mechanism 2 moves the contour jig 23 and the airbag cover below the riveting head 54, the second lifting drive mechanism 52 drives the fixed base 53 to move the riveting head 54 downwards to rivet the hot-melted plastic pin, so that the plastic pin is welded to the airbag cover, thereby welding the emblem onto the airbag cover. This design facilitates the riveting of plastic pins and improves riveting efficiency.

[0030] like Figure 2 As shown, in one embodiment, the detection mechanism 3 of the hot air welding mechanism for the car emblem includes a support frame 31 and a camera detection component 32. The camera detection component 32 is mounted on the support frame 31 and is used to detect the position of the airbag cover and plastic pin on the contour jig 23 of the feeding mechanism 2. After the airbag cover and emblem are fed onto the contour jig 23, the camera detection component 32 takes pictures to detect the assembly position of the plastic pin and the airbag cover. After the detection is qualified, the feeding mechanism 2 drives the airbag cover to perform hot melting and riveting. After the riveting is completed, the camera detection mechanism 3 performs a second detection on the welded airbag cover to ensure the welding quality. This setup realizes the detection of the airbag cover before and after welding, improves the detection accuracy, and ensures the welding quality.

[0031] like Figure 2 As shown, in one embodiment, the horizontal drive mechanism 21 of the car emblem hot air welding mechanism includes a first motor 211 and a first lead screw transmission mechanism 212. The first lead screw transmission mechanism 212 includes a first lead screw and a first nut seat. The first nut seat is threadedly connected to the first lead screw and is connected to the base plate 22. The drive end of the first motor 211 is connected to the first lead screw, and the first motor 211 drives the first lead screw to rotate. The first nut seat drives the base plate 22 and the contour jig 23 to move horizontally along the first lead screw. This horizontal drive mechanism 21 facilitates driving the base plate 22 to move the contour jig 23 to one side of the detection mechanism 3, the hot air mechanism 4, or the riveting mechanism 5, improving applicability.

[0032] like Figure 4As shown, in one embodiment, the workbench 1 of the car emblem hot air welding mechanism is equipped with a sealed housing 6. The feeding mechanism 2, the detection mechanism 3, the hot air mechanism 4, and the riveting mechanism 5 are located inside the housing 6. A window 7 for feeding is provided at one end of the housing 6 near the detection mechanism 3. The airbag cover can be manually fed onto the feeding mechanism 2 through the window 7. The housing 6 improves the safety of personnel operation and ensures personal safety.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.
