[0044] To better understand the technical content of the present invention, the present invention will be further introduced and described below in conjunction with the accompanying drawings and specific embodiments.

The automatic welding machine 6 is equipped with a first conveying mechanism 61, with both ends of the first conveying mechanism 61 protruding from the automatic welding machine 6, serving as a pre-stacking worktable 62 and an output worktable 63, respectively. The automatic riveting machine 7 is equipped with a second conveying mechanism 71, with both ends of the second conveying mechanism 71 protruding from the automatic riveting machine 7, serving as a riveting feed table 72 and a riveting output table 73, respectively. The specific arrangement of each mechanism is as follows: Figure 1 As shown: The horizontally arranged automatic fusion machine 6 serves as the distribution centerline of the entire device. The core board alignment machine 5 and PP alignment machine 3 are respectively located on both sides of the pre-stack worktable 62. The core board feeding machine 4 is located on the side of the core board alignment machine 5 away from the pre-stack worktable 62. The first PP feeding machine 1 is located on the side of the PP alignment machine 3 away from the pre-stack worktable 62. The vertically arranged automatic riveting machine 7 is located on the side of the discharge worktable 63 away from the first PP feeding machine 1, so that the automatic riveting machine 7 and the core board feeding machine 4 are arranged parallel to each other. The discharge machine 20 is located on the side of the automatic riveting machine 7 away from the discharge worktable 63. The second PP feeding machine 2 is located on the side of the discharge machine 20 away from the automatic riveting machine 7. This distribution arrangement facilitates automated production and has a relatively small overall size.

[0047] Among them, the first PP feeding machine 1 is connected to the AGV trolley for external PP transportation, and is used to transport PP with rivet holes one by one to the PP alignment machine 3.

[0048] After receiving the PP from the first PP feeder 1, the PP alignment machine 3 identifies the rivet holes on the PP and adjusts the position of the PP.

[0049] The core board loading machine 4 docks with the AGV trolley for transporting core boards externally, and is used to transport the core boards with rivet holes one by one to the core board alignment machine 5.

[0050] The core plate alignment machine 5 receives the core plate delivered by the core plate feeding machine 4, identifies the rivet holes on the core plate, and adjusts the position of the core plate, so that the rivet holes on the core plate and the PP are corresponded when the core plate and the PP are stacked.

[0063] In an embodiment, the core plate aligning machine 5 includes a core plate aligning position 51 and a CCD 30 arranged above the core plate aligning position 51, when the core plate is conveyed to the core plate aligning position 51, simultaneously uses the CCD 30 to identify the rivet hole on the core plate, to adjust the position of the core plate moved to the core plate aligning position.

[0064] In an embodiment, the second PP feeding machine 2 comprises an entry position 21 for docking with an AGV vehicle transporting PP, a first PP temporary storage position 22 and a second PP temporary storage position 23 for storing PPs of the same or different models, and a fourth moving mechanism 24 for transporting PPs on the first PP temporary storage position 22 and the second PP temporary storage position 23 to the discharging machine 20. The two temporary storage positions can simultaneously store two PPs, solving the problem of low PP conveying efficiency at the same station during continuous pre-arrangement.

[0065] Preferably, the PP entry position 11 and the entry position 21 are recessed positions for AGV vehicles to enter.
