The riveting assembly line 200 is an automated riveting production line for movable pieces of an iron sheet, which is provided with a sequential riveting assembly. The temporary storage station 210, the movable sheet point riveting station 220, the iron sheet loading station 230 and the combined riveting station 240 are arranged at equal intervals in sequence. The transport component 300 is close to the riveting line 200 and is located at the front or rear side of the riveting line 200. In this embodiment, the transport component 300 is located at the front side of the riveting line 200, and is used to transport the movable sheets or movable sheet iron sheet assembly finished products and semi-finished products on the four stations to the next station. The iron sheet loading station 230 is set within the transportable range of the iron sheet loading component 400, and the iron sheet loading component 400 places the iron sheet on the iron sheet loading station 230 and overlaps it with the movable sheet. The movable piece temporary storage assembly 600 is arranged between the movable piece loading assembly 500 and the transport assembly 300, and includes a rotating disk 610 and a plurality of movable piece placement jigs 620 arranged on the rotating disk 610. The movable disk placement jigs 620 are used to place the movable pieces one by one, separate the movable pieces loaded by the movable piece loading assembly 500 one by one, and temporarily store them so as to adapt to the subsequent assembly one by one on the riveting assembly line 200. The middle part of the movable piece placement jig 620 is provided with an upwardly open clamping gap 621, and the movable piece is placed from bottom to top at the opening of the clamping gap 621. The first riveting assembly 700 is arranged near the movable piece point riveting station 220 for processing the point riveting movable piece and installing the rivet on the movable piece. The second riveting assembly 800 is arranged near the combined riveting station 240 for riveting the combined iron sheet movable piece to form a fixed connection structure.

[0042] During specific implementation, the movable piece loading assembly 500 loads the movable pieces neatly in rows and places them one by one on the movable piece temporary storage assembly 600, separates the movable pieces, and loads them one by one; the transport assembly 300 takes the movable pieces from the upper side of the movable piece placement jig 620 according to the assembly line processing speed, and places them on the temporary storage station 210 for temporary storage, and then continues to transport them to the movable piece point riveting station 220, the first riveting assembly 700 installs the rivet on the movable piece of the movable piece point riveting station 220, the transport assembly 300 continues to place the movable piece with the rivet on the iron piece loading station 230, the iron piece loading assembly 400 combines and stacks the iron piece and the movable piece, and transports them to the combined riveting station 240 via the transport assembly 300, the second riveting assembly 800 rivets the iron piece and the movable piece to form a fixed product. The entire process is carried out in an automated manner, separating and loading the movable pieces one by one. Iron sheets are added during the loading process of the movable pieces for assembly and riveting, replacing the traditional manual assembly mode, greatly improving production efficiency, improving riveting quality, and reducing production costs.

[0043] In some embodiments of the present invention, reference Figure 3 and Figure 4 The transport component 300 includes a three-axis motion mechanism 310 and a movable plate 320 arranged on the three-axis motion mechanism 310. The movable plate 320 is provided with temporary storage claws 330, spot rivet claws 340, combined feeding claws 350 and assembly feeding claws 360 which are arranged in sequence and at equal intervals. The temporary storage claws 330, spot rivet claws 340, combined feeding claws 350 and assembly feeding claws 360 correspond to the temporary storage station 210, the movable piece spot riveting station 220, the iron sheet feeding station 230 and the combined riveting station 240 respectively. The interval distance between the temporary storage station 210, the movable piece spot riveting station 220, the iron sheet feeding station 230 and the combined riveting station 240 is equal to the interval distance between the temporary storage claws 330, the spot rivet claws 340, the combined feeding claws 350 and the assembly feeding claws 360, which is the distance of one movement of the movable plate 320. When the movable plate 320 moves the moving distance, all the claws move relative to each other, and the temporary storage claw 330 originally located on the temporary storage station 210 moves to the movable piece spot riveting station 220, and the spot riveting claw 340 located on the movable piece spot riveting station 220 moves to the iron sheet loading station 230. The spot riveting claw 340 and the combined loading claw 350 move the same distance similarly, and the movable piece and the movable piece and iron sheet combination on the previous station in the riveting assembly line 200 can be transported to the next station at the same time, realizing a sequential processing and assembly process, without the need for separately set manipulators or robotic arms to transport between the two stations. The design is ingenious, the structure is simple, and the assembly and riveting of the movable piece and iron sheet are carried out in an orderly manner.

[0044] Specifically, the three-axis motion mechanism 310 includes a transverse rail 311 that slides longitudinally on the base 100, a transverse plate 312 that slides on the transverse rail 311, and a lift seat 313 that slides vertically on the transverse plate 312.
