[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figures 1 to 3 As shown, this embodiment provides a composite riveting assembly processing center for automotive door locks. The center includes a support frame 1, a rotary table 2 mounted on the support frame 1, an assembly fixture 3 mounted on the rotary table 2, and several assembly stations arranged sequentially along the circumference of the rotary table 2: a manual assembly station 4, a detection station 5, a riveting station 6, an inspection station 7, a material unloading station 8, and a conveying station 9. The manual assembly station 4 allows operators to assemble door locks using the assembly fixture 3. The detection station 5 detects whether the assembled door lock is laid flat. The riveting station 6 rivets the door lock detected at the detection station 5. The inspection station 7 inspects the diameter of the riveted door lock. The material unloading station 8 unloads or sprays oil onto the door lock and transports it to the conveying station 9, which transports the door lock to a designated location.

[0022] The automotive door lock composite riveting assembly processing center of this invention arranges the manual assembly station 4, detection station 5, riveting station 6, inspection station 7, unloading station 8, and conveying station 9 sequentially along the circumference of the rotary table 2. With this arrangement, the operator can stand at the manual assembly station 4 and assemble the door lock using the assembly fixture 3. After assembly, the rotary table 2 rotates, moving the assembled door lock to the detection station 5. The detection station 5 then checks whether the assembled door lock is level. After detection, the rotary table 2 continues to rotate, moving the detected door lock to the riveting station 6. The riveting station 6 then rivets the door lock. After riveting, the rotary table 2 continues to rotate, moving the detected door lock to the inspection station 7. The inspection station 7 then checks the diameter of the door lock. After inspection, the unloading station 8 conveys the door lock to the conveying station 9, which finally transports the door lock to the designated location. In this design, while operators are assembling the door locks, the unloading station 8 can also spray oil or unload the door locks. This circular layout effectively solves the skipping or bridging problems that occur in previous continuous or linear layouts. Furthermore, by placing the assembly fixture 3 on the rotary table 2, the assembly fixture 3 is moved via the rotary table 2, preventing sub-assemblies from disrupting the flow. The automotive door lock composite riveting assembly processing center of this invention achieves the riveting assembly and partial testing of door lock cylinders and accessories through a centralized modular composite production line, and has a wide range of applications.

[0023] In this embodiment, there are multiple assembly fixtures 3, which are arranged at circumferential intervals on the rotary table 2. This arrangement of the assembly fixtures 3 in a cyclical manner can eliminate the problems of skipping or bridging sub-assemblies or sub-processes inserted into the flow line that occur in previous continuous or linear layouts.

[0024] Furthermore, the assembly fixture 3 includes a fixture tray 31 and multiple sub-assembly areas 32. The multiple sub-assembly areas 32 are sequentially arranged on the fixture tray 31, allowing the door lock to be assembled sequentially. The fixture tray 31 is positioned on the rotary table 2. Specifically, the multiple sub-assembly areas 32 include a first assembly riveting process, a second assembly riveting process, sub-assembly riveting, a first assembly riveting, and a second assembly riveting, all sequentially arranged on the fixture tray 31.

[0025] In some embodiments, the assembly fixture 3 further includes a pre-assembly oiling area 33. The pre-assembly oiling area 33 is disposed on the fixture tray 31 and spaced apart from multiple sub-assembly areas 32. This configuration allows for oiling of the door lock via the unloading station 8.

[0026] In this embodiment, the detection station 5 includes a detection frame 51 and a detection instrument 52. The detection frame 51 is mounted on the support frame 1 and located on the outer periphery of the rotary table 2. The detection instrument 52 is adjustablely positioned on the detection frame 51, allowing its position to be adjusted according to the position of the assembly fixture 3, thus improving detection accuracy and effectiveness. The detection instrument 52 can be used to detect whether the assembled door lock is laid flat.

[0027] Alternatively, the detection instrument 52 can also be configured as other mechanical detection.

[0028] In some embodiments, the riveting station 6 includes a riveting base 61 and a CNC riveting machine 62. The riveting base 61 is disposed on the support frame 1 and located on the outer periphery of the rotary table 2. The CNC riveting machine 62 is adjustablely positioned on the riveting base 61, so that the position of the CNC riveting machine 62 can be adjusted according to the position of the assembly fixture 3, thereby improving riveting accuracy and riveting effect. The CNC riveting machine 62 can be used to rivet door locks that have been detected at the detection station 5.

[0029] Optionally, the CNC riveting machine 62 can be configured with a PLC program or human-machine interface to set the required riveting dimensions.

[0030] In this embodiment, the inspection station 7 includes a drive assembly 71 and an inspection camera 72. The drive assembly 71 is mounted on the support frame 1 and is driven to the inspection camera 72. This allows the drive assembly 71 to move the inspection camera 72, enabling the inspection camera 72 to detect the diameter of the riveted door lock. The drive assembly 71 is either a linear module or a drive motor. The inspection camera 72 is a CCD camera.

[0031] In some embodiments, the unloading station 8 includes an unloading rack 81, a moving mechanism 82, a height detection mechanism, and an oil spray nozzle mechanism. The unloading rack 81 is disposed on the support frame 1 and located on the outer periphery of the rotary table 2. The moving mechanism 82 is disposed on the unloading rack 81, and both the height detection mechanism and the oil spray nozzle mechanism are disposed on the moving mechanism 82. The moving mechanism 82 can drive the height detection mechanism and the oil spray nozzle mechanism to move to their respective positions, and the moving mechanism 82 can also transport the door lock to the conveying station 9. The height detection mechanism can detect the height of the rivets after the door lock is riveted, and the oil spray nozzle mechanism can spray oil onto the door lock.

[0032] Furthermore, the moving mechanism 82 includes, but is not limited to, a robotic arm.

[0033] In this embodiment, the conveying station 9 includes a good product conveyor belt 91 and a defective product conveyor belt 92. Both the good product conveyor belt 91 and the defective product conveyor belt 92 are mounted on the support frame 1. The good product conveyor belt 91 is used to convey door locks that have passed inspection, and the defective product conveyor belt 92 is used to convey door locks that have failed inspection. This completes the conveying of door locks that have passed or failed inspection.

[0034] It should be noted that, as Figure 4 As shown, the automotive door lock composite riveting assembly processing center based on the present invention has the following main innovation in its assembly process: a large loop ABCDEF on a rotary table serves as the main process loop route, where A, B, C, D, E, and F can be respectively the assembly station, detection station, riveting station, inspection station, unloading station, and conveying station. The assembly station can prevent assembly tooling from being installed, and local loops can be performed within the assembly tooling (1-2-3-4, 5 can be assembled separately), effectively improving assembly efficiency. This setup can also effectively eliminate isolated areas. This main process route can be arranged and combined to produce general-purpose products, and one machine can replace six or more machines previously used. The present invention eliminates the U-shaped line insertion method used in traditional production lines through a centralized modular composite production line, and has a wide range of applications.

[0035] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
