Application number: 17/420,013

Abstract:
An inkjet coating machine is provided to prevent the components in the paint from precipitating. The inkjet coating machine includes: a robot arm having a chuck at a front end and a nozzle head unit detachably mounted on the chuck. The nozzle head unit includes a nozzle head having a nozzle for spraying the paint, a nozzle control unit for controlling driving of the nozzle, and a head-side circulation path enabling the paint to circulate within the nozzle head. The nozzle head, the nozzle control unit and the head-side circulation path are integrally configured. The coating machine further includes a standby holding unit that holds at least one nozzle head unit in standby and a head replacement unit that replaces the nozzle head unit.

Publication number: US20220209615A1
Application number: 17/625,613

Abstract:
It is provided an actuated machine having a main frame 100, a machine shaft 200 mounted on the main frame 100 by means of a bearing module 300, a gearless torque motor 400 coupled to the machine shaft 200 for driving a rotation of the machine shaft 200, a torque arm 500 coupled to the gearless torque motor 400, and a catching structure. The gearless torque motor 400 is coupled to the machine shaft 200 such that the gearless torque motor 400 is capable of following a translational movement of the machine shaft 200. The torque arm 500 is coupled to the gearless torque motor 400 for inhibiting a rotational motion of the gearless torque motor 400, relative to the main frame 100, about a central axis of the gearless torque motor. The catching structure is arranged underneath the gearless torque motor 400 for catching and holding the gearless torque motor 400 in case of a failure causing the gearless torque motor's weight to be no longer carried by the machine shaft 200.

Application number: 17/596,788

Abstract:
A method of calibrating positions of wheels in an AGV, the method including positioning a second wheel tangentially on an imaginary second circle centered with respect to a center position in which a first wheel is fixed; driving the second wheel a second distance along the second circle such that the AGV rotates about the center position; determining the second distance based on data from a second wheel sensor device of the second wheel; determining an angle of rotation about the center position based on data from a first steering sensor device of the first wheel during the rotation of the AGV; and determining relative positions between the first wheel and the second wheel based on the second distance and the angle of rotation. An AGV is also provided.
