An automatized mechanical opening/closing device is mounted to an oven mouth of an oven device and includes an outer door frame assembly, an inner door frame assembly, a door panel, a first driving device, and a plurality of second driving devices. The first driving device and the second driving devices are set in electric connection with a control platform is, so that the first driving device is operable to drive the inner door frame assembly to move inside the outer door frame assembly in an X-axis direction and the second driving devices is operable to drive the door panel to move inside the inner door frame assembly in a Y-axis direction. The control platform can be used to set automatized opening and closing operations of the oven mouth of the oven device to thereby save human labor and to reduce material damage due to manual operation.

A system for monitoring a closed state of a cover of an exposure machine includes a servo motor, a photoelectric encoder, and a controller. A shaft of the servo motor is coaxially fixedly connected to a shaft of the cover. The photoelectric encoder is provided on the servo motor, and is configured to detect an angle of rotation of the shaft of the servo motor. The controller is connected to the servo motor and the photoelectric encoder, and is configured to control rotation of the shaft of the servo motor and determine whether the cover is in the closed state according to the angle.

The disclosure provides a battery swap platform, a battery swap station, and a battery swap method. The battery swap platform includes a parking mechanism, an accommodating mechanism, and an opening and closing mechanism. The accommodating mechanism is arranged below a vehicle parked on the parking mechanism and has an opening, and the opening and closing mechanism is arranged on the accommodating mechanism. When the opening and closing mechanism is in an open state, the opening of the accommodating mechanism can be opened. When the opening and closing mechanism is in a closed state, the opening of the accommodating mechanism can be closed, and the opening and closing mechanism and the parking mechanism form a vehicle passage path for allowing the vehicle to enter or leave the parking mechanism. In the battery swap platform provided according to the embodiment of the disclosure, a load-bearing function of the vehicle passage path is designed to be integrated to the opening and closing mechanism, so that the difficulty in load-bearing design of other apparatuses of the battery swap platform can be reduced.

A latch mechanism includes a latch having a first latch protrusion and a second latch protrusion, and a catch having a first catch protrusion and a second catch protrusion. The first catch protrusion engages the first latch protrusion in a first catch position. The second catch protrusion engages the second latch protrusion in a second catch position following release of the first catch position.

An optoelectronic safety device for monitoring a machine movement includes a detection device and a control device. The detection device includes a transmitter unit which transmits an optical signal having a sequence of signal pulses, each of which has a different pulse intensity, and a receiver unit which receives the optical signal. The control device includes an evaluation unit which evaluates the optical signal received by the receiver unit, a pulse selection index, and a pulse selection unit which changes the pulse selection index if the pulse intensity of one of the signal pulses is outside of an optimal intensity range. The control device enables the machine movement if an intensity of a received signal is within a permissible intensity range, and outputs a trigger pulse to stop the machine movement if the intensity of the received signal is outside of the permissible intensity range.

A machine tool includes: a cover; a door; a drive mechanism; a detection unit; and an operation panel that receives an operation for the machine tool. A control device of the machine tool performs: processing to control the drive mechanism such that the door is opened, based on the operation panel receiving a first opening operation; processing to obtain an actual position from the detection unit and store the actual position as an opening position of the door, based on the operation panel receiving an operation to determine a position; and processing to control the drive mechanism such that the door is located at the opening position, based on the operation panel receiving a second opening operation. An opening speed of the door during the first opening operation is slower than an opening speed of the door during the second opening operation.

Friction hinge (21) for the pivotable connection of two components, comprising at least one first hinge sleeve (24) which is arranged in alignment with at least one further hinge sleeve (22), a shaft (11) which runs through the hinge sleeves (22, 24), and at least one friction spring for exerting a friction torque on the movable shaft (11), wherein at least two mutually aligned friction springs (10, 10′) are connected to the first hinge sleeve (24) via radial shoulders (16, 16′) and exert a friction torque on the shaft (11) mounted in the further hinge sleeve (22).

Covering device suitable for an apparatus for feeding bars to a machine tool, includes: a support frame, rotatably connectable, by first hinge elements, to a frame structure of the feeding apparatus, a cover element rotatably connected, by second hinge elements, to the support frame. The first hinge elements and the second hinge elements are arranged on respective longitudinal sides, opposite one another, of the support frame and are configured to enable the covering device to be opened, at will, both from one side and the other side of the feeding apparatus. On the cover element a slit opening is obtained that extends longitudinally, configured to enable bars to move from external auxiliary storage to a drum of the feeding apparatus.

A sliding door assembly (50) for an inductively coupled plasma torch box (40) reduces the risk of heat related injuries and facilitates the handling of the torch box. The door assembly (50) comprises a door and a guiding mechanism (6) for allowing movement of the door in a first direction along an opening (45) of the torch box (40) so as to be able to open and close the torch box, and allowing movement of the door in a second direction, substantially perpendicular to the first direction, so as to move the door or at least a part thereof towards the opening when closing the torch box. The door may comprise an inner door panel interconnected with an outer door panel, so that only the inner door panel moves in the second direction, towards the opening (45) of the torch box (40) to tightly close it, while the outer door panel can maintain a safe temperature during operation.
