[0033] In order to realize the automation of screw installation, in this embodiment, the screw installation assembly 300 includes a bracket 320 arranged above the first conveyor line 100, and a mounting structure 310 connected to the bracket 320 through a driving module 500, and the mounting structure 310 and the driving module 500 drive the mounting structure 310 to move along the X-axis, Y-axis and Z-axis relative to the positioning assembly 200.

[0039] In this embodiment, a slider structure 330 is further provided on the placement plate 322 and is arranged opposite to the X-axis module 510. The slider structure 330 is flush with the X-axis module 510 and maintains a moving distance, and is connected to the end of the Y-axis module 520 away from the X-axis module 510. While ensuring the stability of the support at both ends of the Y-axis module 520, it can also make the Y-axis module 520 move more smoothly on the X-axis module 510, effectively improving the stability of the assembly.

[0040] In this embodiment, the slider structure 330 includes a guide rail 331 detachably disposed on the placement plate 322 , and a slider 332 having one side slidably connected to the guide rail 331 and the other side detachably connected to the Y-axis module 520 .

[0043] In order to realize the automation of the withstand voltage test, in this embodiment, the withstand voltage test assembly 400 includes a connection structure 410 located at the adjacent side of the first conveyor line 100 and moving relative to the positioning assembly 200, and the connection structure 410 has a first moving position and a second moving position. When the connection structure 410 is in the first moving position, the connection structure 410 is connected to the inverter 700 to automatically perform the withstand voltage test. When the connection structure 410 is in the second moving position, the connection structure 410 is separated from the inverter 700 so that the inverter 700 after the test enters the next process. Among them, the withstand voltage test can be carried out simultaneously with the screw tightening, which further improves the work efficiency while realizing the automation of the withstand voltage test.

[0044] In this embodiment, the connection structure 410 is detachably connected to the first conveyor line 100 or the screw installation assembly 300, and moves linearly toward or away from the positioning assembly 200, and the height of the connection structure 410 is adapted to the height of the positioning assembly 200.

[0045] In this embodiment, the connection structure 410 includes a connection plug 411 and a driving member 412. The output end of the driving member 412 is connected to the connection plug 411. The driving member 412 drives the connection plug 411 to move between a first moving position and a second moving position. The connection plug 411 is adapted to the height of the inverter 700, and a test connector (not shown in the figure) adapted to the plug is provided on the inverter 700. When the connection plug 411 is in the first moving position, the connection plug 411 is connected to the test connector. When the connection plug 411 is in the second moving position, the connection plug 411 is separated from the test connector. By automating the movement of the connection plug 411, the inverter 700 is ensured to be accurately connected and separated from the connection structure 410, thereby improving the test efficiency and reliability.

[0046] In this embodiment, the voltage withstand test assembly 400 also includes a connecting seat 420 and a dedicated voltage withstand tester (not shown in the figure) that forms an electrical connection with the connecting plug 411. The connecting structure 410 is detachably arranged on the outside of the support frame of the first conveyor line 100 through the connecting seat 420, and the connecting plug 411 and the driving member 412 are respectively perpendicular to the positioning assembly 200 to realize convenient installation and disassembly of the connecting plug 411 and the driving member 412.

[0047] Preferably, in this embodiment, the connection structure 410 and the connection seat 420 can be provided in two groups, which are detachably provided on both sides of the first conveyor line 100. Through the design of the double-sided connection structure 410, if any one group of the connection structures 410 fails, the other group of the connection structures 410 can take over the work, which effectively reduces the risk of the test equipment shutting down due to failure.

[0048] In the present embodiment, a plurality of second conveyor lines 600 are arranged vertically with respect to the first conveyor line 100, and detection sensors (not shown in the figure) are respectively provided at both ends of the second conveyor line 600, and the detection sensors are used to detect the storage capacity of the inverter 700 on the second conveyor line 600.
