Description

Technical Field

[0001] The present invention belongs to the field of automobile manufacturing, and particularly relates to a hemming island for the front and rear covers of an automobile. Background Art

[0002] With the rapid development of the automobile industry, the shape of the automobile hood has become increasingly complex and sharp, such as a large flanging angle of the outer panel. The traditional pressing process can no longer meet the manufacturing process requirements, and instead, the robot hemming process, that is, the robot hemming island, is widely used. Currently, the robot hemming process is often used to hem the hood, that is, the robot hemming program is used to control the robot to achieve different hemming trajectories, which has high flexibility and can realize mixed-line production of multiple vehicle models. It has been widely applied to the door and hood line in the welding workshop of automobile factories.

[0003] The robot hemming island usually consists of a hemming robot, hemming equipment, a gluing system, a vision system, a control system, and safety facilities, etc. All the equipment works together according to the set steps to complete the hood hemming work. For a specific vehicle model or a production mode with a low beat, the die change of the robot hemming island generally adopts forms such as a linear slide guide rail form, a single-station turntable form, a double-station turntable, etc. The existing robot hemming island can import 6 vehicle models. It adopts a "square" layout scheme. Each time the vehicle model is switched, the six vehicle model dies rotate in a cycle according to the set steps. Each time the motor transports one vehicle model die, and the other vehicle model dies wait, resulting in a long vehicle model switching time. In addition, the vehicle model die change steps of the existing robot hemming island are cumbersome, the PLC (Programmable Logic Controller) program logic for vehicle model switching is complex, and the operation failure rate is high.

[0066] Specifically, the first robot 81 is optional but not limited to the "upper / lower part robot for the front and rear cover assembly".

[0073] Specifically, the fourth station 88 is used for installing the upper part of the inner panel of the front / rear cover.

[0074] The working principle of the front and rear cover flanging island of the vehicle is as follows:

[0075] By simplifying the switching route of the vehicle model die 7, the switching efficiency is improved. At the same time, the PLC program is also simplified, and the operation failure rate is reduced.

[0076] Among them, multiple storage positions 4 are respectively arranged on both sides of the chassis 11 according to requirements. Then, the conveying structure 3 is successively installed on the conveying position 1, the pushing structure 6 is installed on the storage position 4, and the vehicle model die 7 is installed on the pushing structure 6. After the installation is completed, according to the preset processing sequence, the conveying structure 3 slides to the pushing structure 6 where the vehicle model die 7 needs to be switched. At the same time, the limit connecting part 5 is connected to the limit rolling part 2 according to the preset induction condition, so that the pushing guide plate 411 is flush with the conveying guide plate 34. Then, the second driving source 62 is used to drive the second gear 63 to rotate. The second gear 63 meshes with the second rack 42 to drive the vehicle model die 7 to slide towards the conveying structure 3. During the sliding process, the vehicle model die 7 slides from the pushing guide plate 411 to the conveying guide plate 34. After completely sliding onto the conveying guide plate 34, the driving ends of the first positioning 351 and the second positioning 352 both limit the vehicle model die 7. At this time, the limit connecting part 5 is separated from the limit rolling part 2 according to the preset induction condition. The first driving source 32 drives the first gear 33 to rotate. The first gear 33 meshes with the first rack 12 to drive the vehicle model die 7 to slide towards the processing equipment 8. After sliding to the processing equipment 8, the first positioning 351 and the second positioning 352 terminate the limit according to the preset conditions, and then the processing equipment 8 processes the vehicle model die 7 according to the preset conditions.

[0077] After the processing is completed, the driving ends of the first positioning 351 and the second positioning 352 limit the vehicle type membrane 7 again, and the first driving source 32 drives the conveying frame 31 to return to the position of switching the vehicle type membrane 7. While returning to the position, the limiting connector 5 is connected to the limiting roller 2 according to the preset sensing conditions, and the switching groove 71 on the vehicle type membrane 7 also frames the switching wheel 611 on the support plate 61. When the second driving source 62 drives the pushing structure 6 to slide in the opposite direction, the switching wheel 611 transmits the pulling force to the vehicle type membrane 7, so that the vehicle type membrane 7 slides from the conveying guide plate 34 to the pushing guide plate 411 until it returns to the original storage position 4, thereby completing the hemming process of a single vehicle type membrane 7. By analogy, the hemming process of the remaining vehicle type membranes 7 is completed.

[0078] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
