Specifically, the feeding module 200 includes a motor carrier 210, a feeding power assembly and a feeding piece, the feeding power assembly is installed on the mounting platform 110, the feeding piece is connected to the output end of the feeding power assembly, the motor carrier 210 is arranged on the feeding piece, and the motor carrier 210 includes a motor positioning block 2103, and the motor positioning block 2103 can place the motor body 700 to be welded. Furthermore, the welding system includes a first moving mechanism and a welding electrode. The first moving mechanism is installed on the mounting table 110 and is located on one side of the feeding piece. The welding electrode is connected to the output end of the first moving mechanism. The welding motor is located above or below the motor body 700 and facing the motor body 700.

[0039] like Figure 1 、 3 As shown in Figure 4, in this embodiment, the feeding power component is a divider 230 component, the feeding component is a turntable 240, the output end of the divider 230 component is connected to the turntable 240, and the above-mentioned motor carrier 210 is arranged on the outside of the turntable 240. Specifically, the feeding module 200 also includes two groups of flip assemblies 220, and the number of motor carriers 210 is four groups. The above-mentioned welding system includes a first spot welding module 300 and a second spot welding module 400, and the first spot welding module 300 and the second spot welding module 400 both include an upper electrode 350 and a first lower electrode portion 360. Furthermore, the first spot welding module 300 and the second spot welding module 400 are both installed on the mounting table 110, and the four groups of motor carriers 210 are evenly arranged along the circumference of the turntable 240. Two motor carriers 210 are located at the first spot welding module 300 and the second spot welding module 400, respectively, and another two motor carriers 210 are located at the loading area. The two flipping assemblies 220 are both located above the divider 230 assembly, and the output ends of the two flipping assemblies 220 are directed toward the two motor carriers 210 located at the first spot welding module 300 and the second spot welding module 400, respectively. Since the structure and method of the divider 230 assembly and the turntable 240 for conveying materials are both mature existing technologies, they will not be described in detail in this embodiment.

[0040] In this embodiment, the flip assembly 220 includes a pad, a main board 2204, a flip displacement track, a flip displacement cylinder 2203, a flip mounting plate, a flip motor 2201, a planetary reducer 2202, a coupling, a top post, and a rotating shaft. Specifically, the pad is positioned on the top surface of the divider 230 assembly, and the main board 2204 is mounted on the pad. The pad and main board 2204 are spaced from the output end of the divider 230 assembly and the turntable 240. Furthermore, the flip displacement track and flip displacement cylinder 2203 are both mounted on the main board 2204, while the flip mounting plate is mounted on the flip displacement track. The output end of the flip displacement cylinder 2203 is connected to the flip mounting plate. Furthermore, the flip motor 2201, planetary reducer 2202, coupling, top column, and rotating shaft are all installed on the flip mounting plate, and the output end of the flip motor 2201, planetary reducer 2202, coupling, top column and rotating shaft are connected in sequence, and the rotating shaft is detachably connected to the motor carrier 210.

[0041] When the turntable 240 rotates to transport the motor body 700, the central rotating shaft and the end of the carrier mounting shaft 21011 are separated, so that the turntable 240 drives the motor carrier 210 to rotate and change position, thereby moving to the welding position and the loading and unloading position. When the motor bodies 700 on two sets of motor carriers 210 are welded, and when the other two sets of motor carriers 210 are manually loaded and unloaded, the flip mounting plate can be moved by the flip displacement cylinder 2203 to engage the central rotating shaft with the end of the carrier mounting shaft 21011, so that the two sets of motor carriers 210 can be flipped by the rotating shaft, so that the motor body 700 faces the upper electrode 350 or the first lower electrode portion 360, thereby performing the welding operation. In this embodiment, when the motor carrier 210 is facing upward, the side of the motor body 700 to be welded faces the upper electrode 350, so that the motor body 700 is welded through the upper electrode 350; when the motor carrier 210 is flipped over, the side of the motor body 700 to be welded faces the first lower electrode part 360, so that the motor body 700 is welded through the first lower electrode part 360.

[0042] like Figure 1 、 3As shown in Figures 5 and 6, the motor carrier 210 also includes a carrier base plate 2101, a carrier mounting shaft 21011, a bearing fixing seat 21012, a flip limiting portion 21013, a carrier mounting plate 2102 and a clamping structure, wherein the number of the bearing fixing seats 21012 is two, and the number of the flip limiting portion 21013 and the clamping structure are both two groups. Specifically, the carrier base plate 2101 is mounted on the outside of the turntable 240. Two bearing mounts 21012 are sequentially mounted on the top surface of the carrier base plate 2101 along the radial direction of the turntable 240. Two sets of flip limiters 21013 are both located on the side of the carrier base plate 2101 near the flip assembly 220. The two ends of the carrier mounting shaft 21011 are respectively mounted on the two bearing mounts 21012. The carrier mounting plate 2102 is mounted on the carrier mounting shaft 21011. The motor positioning block 2103 and the clamping structure are both located on the carrier mounting plate 2102. In this embodiment, the flip limiter 21013 includes a clamping block, and the flip assembly 220 includes a push rod. When the central rotating shaft is separated from the carrier mounting shaft 21011, the clamping block engages with the carrier mounting plate 2102, thereby locking the carrier mounting plate 2102 to prevent it from turning over. When the turning assembly 220 is driven by the turning displacement cylinder 2203 to engage the central rotating shaft with the carrier mounting shaft 21011, the push rod will abut against the turning assembly 220, causing the clamping block to separate from the carrier mounting plate 2102, thereby allowing the central rotating shaft to drive the carrier mounting plate 2102 to turn over through the carrier mounting shaft 21011 for welding. The structure of the turning limiter 21013 locking the carrier mounting plate 2102 via the clamping block is a mature existing technology and will not be described in detail in this embodiment.

The middle portion of the first locking member is threadedly connected to the first mounting hole, and the lower end of the first locking member can abut against the clamping block slide 21041. The handle 21042 is arranged at the upper end of the first locking member. The first locking member is used to lock the position of the motor clamping block 2104 on the clamping block slide 21041. This is a mature existing technology and will not be described in detail in this embodiment.

[0044] During loading and unloading, the worker can turn the handle 21042 to loosen the motor clamping block 2104. After loading, the worker can move the motor locking block along the clamping block slider and then lock it with the handle 21042 to clamp the motor body 700.

In addition, the accessory clip includes a second limit rod, which is movably disposed on the side of the accessory clip facing the accessory clip limit plate. When the accessory clip limit plate rotates to be parallel to the accessory clip slide rail, the accessory clip limit plate can abut against the accessory clip. When the accessory clip limit plate rotates to be perpendicular to the accessory clip slide rail, the second limit rod can engage with the accessory clip limit plate.

[0046] In this embodiment, the accessory clip, accessory clip rail, and accessory clip stop plate are provided in two sets, each located on either side of the rear end of the motor positioning block 2103.

The spot welding displacement cylinder 320 can also be used to drive the upper electrode 350 to move along the Z-axis. This can accommodate different motor bodies 700 to be welded, as well as different displacement requirements before, after, and during welding. Since the three-axis transfer mechanism 310 is a mature existing technology, it will not be described in detail in this embodiment.
