In other embodiments, the first conveyor line 100 can also adopt a power-and-free conveyor chain, which is not particularly limited.

[0029] according to Figure 3 、 Figure 5 and Figure 7 As shown, the hanger tracking and correction device 200 includes a support frame 201, a movable base 203, a driving mechanism 204, and a clamping mechanism 205. The movable base 203 is movably arranged on the support frame 201 between a first position and a second position, and a support portion 202 is provided on the movable base 203.

The clamping mechanism 205 is arranged on the movable base 203. The clamping mechanism 205 is configured to: clamp the lower end of the hanger 101 on the support portion 202 when the hanger 101 moves to the first position, and release the hanger 101 when the hanger 101 leaves the second position.

[0030] By setting a correction station on the conveying path of the first conveyor line 100, the correction station has a first position and a second position arranged downstream of the first position, and the hanger tracking correction device 200 sets the movable seat 203 movably between the first position and the second position on the support frame 201, and drives the movable seat 203 through the driving mechanism 204 on the support frame 201, so that the movable seat 203 moves to the second position synchronously with the hanger 101 when the hanger 101 moves to the first position, and clamps the lower end of the hanger 101 on the support part 202 of the movable seat 203 through the clamping mechanism 205, so as to keep the position of the hanger 101 from shaking, tilting or offsetting, so as to facilitate the rotating hanging robot to grab the workpiece 102 from the hanger 101 more accurately.

[0031] Specifically, the support frame 201 is provided with a movable track 206 extending from a first position to a second position.

When the drive motor 208 is activated, it drives the movable base 203 to move in a first direction from the first position to the second position. When the drive motor 208 is reversed, it drives the movable base 203 to return from the second position to the first position.

[0032] The clamping mechanism 205 includes a clamping cylinder 213, a sliding seat 214, and a clamping member 215. The clamping cylinder 213 is mounted on the movable seat 203. The sliding seat 214 is movably disposed on the movable seat 203 along a second direction perpendicular to the first direction. The clamping cylinder 213 is in transmission connection with the sliding seat 214. The clamping member 215 is disposed on the sliding seat 214. In other embodiments, a motor may be used to drive the sliding seat to move, which is not particularly limited.

[0033] Specifically, a slide rail 216 is provided on the movable base 203 along the second direction. A pulley 217 is rotatably provided at the bottom of the sliding base 214, and the pulley 217 is supported on the slide rail 216.

When the hanger 101 moves along the transport path to the first position of the correction station, the first sensor sends a detection signal to the controller, and the controller controls the drive motor 208 and the clamping cylinder 213 to start. The drive motor 208 drives the movable seat 203 to move synchronously with the hanger 101 from the first position to the second position, and the clamping cylinder 213 drives the sliding seat 214 along the first position to the second position. Figure 6The second direction shown causes the sliding seat 214 to drive the clamping member 215 and move closer to the hanger 101, clamping the lower end of the hanger 101 on the support portion 202 of the movable seat 203. When the hanger 101 continues to move and leaves the second position, the second sensor sends a detection signal to the controller, which controls the drive motor 208 to stop and start reverse rotation to return the movable seat 203 from the second position to the first position; at the same time, the controller controls the clamping cylinder 213 to drive the sliding seat 214 to move in the opposite direction along the second direction, causing the sliding seat 214 to drive the clamping member 215 and move away from the hanger 101, releasing the lower end of the hanger 101 from the support portion 202 of the movable seat 203.
