[0049] The present invention provides an automobile production line 1000, which is mainly used for producing the front body of an automobile, and can also be used for producing other parts of an automobile.

[0050] Reference Figures 1 to 4 The production line of the present invention includes a manufacturing system 200, a transportation system 100 and a master control system. The manufacturing system 200 includes an assembly island 210 and a repair welding island 220, and the assembly island 210 and the repair welding island 220 are arranged at intervals; the transportation system 100 includes a conveying track 10 and an AGV conveying mechanism 30, and the conveying track 10 passes through the assembly island 210 and the repair welding island 220 in sequence. The AGV conveying mechanism 30 includes an AGV trolley 31 and a support assembly 32. The AGV trolley 31 moves through the conveying track 10, and the support assembly 32 is movably connected to the AGV trolley 31 and can move along the first direction and the third direction; the support assembly 32 is used to support first parts 300 of different models; the AGV trolley 31 conveys first parts 300 of different models to the assembly island 210 and / or the repair welding island 220; the manufacturing system 200 and the transportation system 100 are both electrically connected to the master control system, and the master control system is used to control the operation of the manufacturing system 200 and the transportation system 100.

[0051] In some embodiments of the present invention, the manufacturing system 200 is used to weld and assemble the front body of the automobile, the transportation system 100 is used to transport the first part 300 to be assembled to the manufacturing system 200, and the master control system is used to control the operation of the manufacturing system 200 and the transportation system 100 to improve the working efficiency of the production line 1000 of the automobile of the present invention.

[0052] It can be known that in the relevant technology, the automobile production line 1000 is usually set to be linear, that is, multiple workstations are connected in sequence. If the production line needs to produce two or more models at the same time, it is necessary to stop at each workstation, which will increase the production time and reduce the production efficiency. For this reason, in the production line of the present invention, a transportation system 100 is set, and the conveying track 10 of the transportation system 100 is passed through the assembly island 210 and the repair welding island 220 to connect the assembly island 210 and the repair welding island 220. The AGV conveying mechanism 30 of the transportation system 100 transports the first part 300 to the assembly island 210 and the repair welding island 220 through the conveying track 10, so that the front body of multiple models of automobiles can be produced at the same time to improve the production efficiency of the production line of the present invention.

[0053] Through the above arrangement, the AGV trolley 31 of the AGV conveying mechanism 30 can serve as the transport body for transporting the first part 300, and the support assembly 32 can support and position the first part 300, thereby maintaining the structural stability of the first part 300 when moving between different working islands. At the same time, the support assembly 32 and the AGV trolley 31 are configured as a movable connection, so that the support assembly 32 can adapt to first parts 300 of different models (i.e., different sizes), thereby improving the usability of the AGV conveying mechanism 30. The first part 300 mentioned above can be the floor of the front vehicle body, of course, it can also be other structures of the front vehicle body, which is not limited here.

[0054] Further, refer to Figure 1 and Figure 2 In one embodiment of the present invention, there are multiple assembly islands 210 and multiple welding repair islands 220. Multiple assembly islands 210 are arranged at intervals along the first direction, and multiple welding repair islands 220 are arranged at intervals along the first direction; one assembly island 210 matches at least one welding repair island 220.

[0055] In this embodiment, the number of assembly islands 210 and repair welding islands 220 is set to be multiple, and the multiple assembly islands 210 are arranged at intervals along the first direction. The assembly islands 210 for assembling different models are arranged separately, which can reduce the mutual influence in the production process; the capabilities of different working islands are different. The overall structure of the repair welding island 220 is simpler than that of the assembly island 210, and its working speed is faster. Generally, one assembly island 210 is matched with one repair welding island 220. Of course, according to the different numbers of welding points of different models, one assembly island 210 can also be matched with multiple repair welding islands 220.

[0056] It can be seen that the number of repair welding islands 220 can be increased or decreased according to the number of welding points of different models, so as to save costs to the greatest extent; and the assembly island 210 and the repair welding island 220 can be set adjacent to each other to achieve the shortest conveying route of the AGV conveying mechanism 30, thereby further improving the production efficiency of the production line.

[0057] Further, refer to Figure 1 and Figure 2 In one embodiment of the present invention, the assembly island 210 includes a plurality of placement devices 215, a gripping device 213, a first visual positioning device and a first welding device 211. The plurality of placement devices 215 are respectively used to place different types of automotive parts 400; the gripping device 213 is spaced apart from the placement devices 215, and the first visual positioning device is disposed on the gripping device 213. The first visual positioning device is used to locate the position of the placement device 215, and the gripping device 213 is used to grip the automotive part 400; the first welding device 211 is spaced apart from the gripping device 213, and the first welding device 211 is used to weld the first part 300 and the automotive part 400.

[0058] In this embodiment, each storage device 215 is used to store different types of auto parts 400. Specifically, each storage device 215 stores one type of auto part 400. For example, if one storage device 215 stores the right front panel, then the storage device 215 corresponding to it along the second direction stores the left front panel. Other storage devices 215 can store the left front wheel housing, the right front wheel housing, the front frame, or the front panel. When different models of automobiles are produced, the storage devices 215 store the auto parts 400 corresponding to the model. The storage devices 215 can be three-dimensional storage cabinets, material racks, or other devices with storage functions, without limitation.

[0059] The first visual positioning device can be used to position the frame of the storage device 215, so that the grasping device 213 can reduce the possibility of hitting the frame of the storage device 215 during the process of grasping the automobile part 400, thereby improving the grasping accuracy of the grasping device 213; when the AGV car 31 transports the first part 300 to the assembly island 210, the grasping device 213 places the grasped automobile part 400 on the first part 300. Generally, an angle will be formed between the two. At this time, the first visual positioning device is used to take a picture of the connection between the two, and the photographed image is transmitted back to the main control system. The main control system issues instructions to the first welding device 211, and the first welding device 211 welds the connection between the two, thereby completing the partial installation of the front body.

[0060] As can be seen, the assembly island 210 also includes a lifting device 217, which is used to position the support assembly 32 and move the support assembly 32 along the third direction into the working range of the first welding device 211. The lifting device 217 is used to separate the support assembly 32 from the AGV 31 and lift the support assembly 32 and the first part 300 it supports along the third direction into the working range of the gluing device and the first welding device 211, thereby improving the working efficiency of the assembly island 210.

[0061] Specifically, the lifting device 217 can be a multi-column lift, a scissor-arm lift mechanism, a hydraulic cylinder lift, or other types of lifting devices 217, which are not limited here.

[0062] It can be known that the assembly island 210 also includes a gluing device and a second visual positioning device, and the second visual positioning device is arranged on the gluing device; the gluing device, the gripping device 213 and the first welding device 211 are arranged in sequence at intervals, the second visual positioning device is used to locate the welding point between the first part 300 and the automobile part 400, and the gluing device is used to bond the connection between the first part 300 and the automobile part 400.

[0063] The gluing device, gripping device 213, and first welding device 211 are spaced apart to minimize interference between them during operation due to their proximity. Gluing is performed before welding. Specifically, the gluing process ensures that the temperatures of the first part 300 and the automotive part 400 are within a set range to minimize glue shedding after application. The gluing nozzle in the gluing device then applies spot welding structural adhesive to the coated surfaces of the welded overlaps of the first part 300 and the automotive part 400. After gluing is complete, the first welding device 211 is used to weld the two components. Gluing ensures a stronger and more reliable bond between the welded components, improving the overall quality of the front vehicle body.

[0064] It can be known that the grasping device 213 can be a clamping robot or a robotic arm equipped with a suction cup, which can reduce its loss during the clamping process by adsorbing the first part 300 through the suction cup; each visual positioning device or visual positioning structure 325 in the present invention can be an industrial camera, each welding device can be a welding robot or a robotic arm, and the gluing device can be a gluing robot or a robotic arm.

[0065] During the welding process on assembly island 210, two welded parts may have quality issues, such as incomplete welds, cracks, or pores. In this case, repair welding island 220 is needed to repair the welds between the two parts so that they can meet the predetermined quality standards. After welding is completed on assembly island 210, the first visual positioning device can take a picture of the welds between the two parts. After comparing the pictures with the preset pictures within the system, the master control system determines whether to enter repair welding island 220. If not, the next assembly island 210 can be entered for the next assembly step. If necessary, the repair welding island 220 is entered for repair welding.

[0066] refer to Figure 1 and Figure 2 In one embodiment of the present invention, the repair welding island 220 includes a second welding device 221 and a third visual positioning device, and the third visual positioning device is arranged on the second welding device 221; the third visual positioning device is used to determine the stop position of the AGV trolley 31, and the second welding device 221 is used to repair the connection between the first part 300 and the automobile part 400.

[0067] In this embodiment, the third vision positioning device interacts with the vision positioning structure 325 of the AGV conveyor mechanism 30, allowing the second welding device 221 to know the exact location of each AGV stop, enabling the second welding device 221 to perform accurate welding. Furthermore, the third vision positioning device can photograph the welds between the first part 300 and the automotive part 400 to determine the areas that the second welding device 221 needs to weld. The second welding device 221 adjusts its trajectory based on the deviations transmitted by the third vision positioning device to achieve accurate welding.

[0068] refer to Figures 3 to 5 In one embodiment of the present invention, the support assembly 32 includes a mobile module 321, a support module 322 and a drive module 323. The mobile module 321 is slidably connected to the AGV cart 31; the support module 322 is arranged on the side of the mobile module 321 away from the AGV cart 31, and the mobile module 321 moves to drive the support module 322 to move along the first direction and / or the third direction; the drive module 323 is transmission-connected to the mobile module 321 to drive the movement.

[0071] It can be known that the motion guide rail 321a is used to determine the movement direction of the sliding member 321b, and the connecting member 321c is used to connect the two sliding members 321b arranged opposite to each other so as to synchronize their movement, that is, to synchronize the movement of the support module 322 to improve the adjustment efficiency. The motion guide rail 321a can be extended along the first direction or along the second direction, which is not limited here. The sliding member 321b can be a sliding block, the connecting member 321c can be a connecting plate, and the driving module 323 can include a first driving member 323a and a second driving member 323b. The first driving member 323a is transmission-connected to the connecting member 321c to drive the connecting member 321c to move in the first direction or the second direction.

[0072] Specifically, the support module 322 may include at least one group of first support members 322a, at least one group of second support members 322b and at least two groups of clamping members 322c arranged at intervals, wherein one group of first support members 322a is arranged on the connecting member 321c, and one group of second support members 322b is arranged on the moving guide rail 321a; one group of first support members 322a approaches or moves away from a group of second support members 322b as the connecting member 321c moves; one group of clamping members 322c is arranged at a group of first support members 322a, and another group of clamping members 322c is arranged at another group of second support members 322b, and the clamping members 322c are used to clamp and position the first part 300.

[0073] As can be seen, a set of first support members 322a is disposed on the connecting member 321c. The first support members 322a can move along with the connecting member 321c. A sliding plate 322d can be disposed between the two first support members 322a. The sliding plate 322d is slidably connected to the two first support members 322a.
