After the saggars 6 are filled with the material, the sagger conveying device 8 sends the saggars 6 out, and at the same time, sends new saggars 6 to the sagger loading stations, and the cycle is repeated.

[0040] The automatic film placing machine further comprises a sagger taking device 9 and a sagger stacking frame 10, which are respectively installed on the frame 1. The sagger taking device 9 is provided with a sagger taking station and a sagger placing station. The sagger taking station of the sagger taking device 9 corresponds to the position of the discharging end of the sagger conveying device 8, and the sagger placing station of the sagger taking device 9 corresponds to the position of the sagger stacking frame 10. After the saggars 6 are filled with the material, the saggars 6 are conveyed to the discharging end by the sagger conveying device 8, and then the sagger taking device 9 takes the saggars 6 away at the sagger taking station and stacks the saggars 6 in the sagger stacking frame 10. The sagger taking device 9 can be an industrial robot with multiple degrees of freedom. The robot end effector at the end of the mechanical arm of the industrial robot can hold the saggars 6. The robot end effector can be a mechanical claw (for example, a finger cylinder with two clamping jaws) driven by a cylinder, which can grip and release the saggars 6 by driving the cylinder.

[0041] The first translation driving mechanism 403, the third translation driving mechanism 302, the fourth translation driving mechanism 503 and the lifting driving mechanism 502 all adopt cylinders.
