After embroidery is completed, the whole piece of cloth is cut according to the subsequent processing needs to improve the embroidery processing efficiency. Therefore, an embroidery machine is provided below each embroidery station in the X direction, and the embroidery machine is used for supplying embroidery thread. The installation position of the core shell is provided inside the installation position. The Y direction is inserted and fixed with the core shell of the embroidery thread winding.

[0003] In the prior art, a line changing robot is used to replace the core shell of the embroidery machine in multiple stations:

The three-axis delivery unit includes a double-axis mechanical arm and a translation tray. The clamping end of the double-axis mechanical arm is three-axially connected to the translation tray to replace and deliver the core shell to the station of the embroidery machine. The device aims to improve the positioning and clamping accuracy of the mechanical claw relative to the core shell, effectively increases the core shell carrying capacity in the device, and reduces the force load on the power supply track of the overall device to solve the problems of poor positioning accuracy and low delivery efficiency of the core shell delivery device in the prior art.

[0005] For example, the second generation product of the applicant: CN2025203521485 - discloses a balance level stress embroidery machine core shell delivery device. The delivery device includes a power supply rail and a three-axis delivery unit. The three-axis delivery unit includes a Z-shaped structure of a translation plate, a double-axis mechanical arm, and a translation tray. The middle of the translation plate is integrally formed with a Y-direction extending bending part. The bending part is slidably connected to the top and side wall of the power supply rail in the X direction. The translation plate side wall above the power supply rail slidably supports the translation tray in the X direction. The double-axis mechanical arm on the side wall of the translation plate beside the power supply rail is arranged to lift and stretch the core shell on the translation tray in the Z and Y directions.
