Embodiment 1

[0028] The invention provides a shutter device, such as Figure 1-Figure 5 As shown, it includes a fixed platform 1, an adapter plate 2 and a water-cooled head module 3. The fixed platform 1 is provided with a voice coil linear motor 4, and the top of the voice coil linear motor 4 is connected with an adapter plate 2. There is a first through hole, and a second through hole is opened on the water cooling head module 3, organic rice screws are movably connected in the first through hole and the second through hole, so that the top of the adapter plate 2 passes through the organic rice screw and the water cooling head module The 3 axis holes are matched and connected so that the water cooling head module 3 can move axially relative to the adapter plate 2 but cannot move radially. The water cooling head module 3 is provided with a light hole 5; After passing through the adapter plate 2, it is connected to the bottom of the water-cooled head module 3; a grating scale 6 is installe...

Embodiment 2

[0034] like Image 6 As shown, in another embodiment, the spring 7 used in the shutter device of the present invention is replaced by a constant force magnetic spring. Constant force magnetic springs, unlike traditional mechanical springs, can provide a constant push or pull force over the entire travel range. This series of products adopts an innovative magnetic circuit design, which realizes gravity compensation and offset through a magnetic field, and has a simple structure, including only two components, the stator and the mover. The constant force magnetic spring is a completely passive device, which can achieve constant force output without any external energy supply, such as hydraulic pressure, air pressure, power supply, etc. It is the most ideal choice for applications that require high system safety factors, constant thrust or constant tension, including smooth tension and recovery, balance mechanism applications, tension load applications, gravity compensation and ...

Abstract

The invention discloses a shutter device and relates to the technical field of shutter equipment. The device comprises a fixed platform, a voice coil linear motor is arranged on the fixed platform, the top of the voice coil linear motor is connected with an adapter plate, the top of the adapter plate is connected with a water cooling head module in a matched mode through a set screw shaft hole, and a light through hole is formed in the water cooling head module; a motor rotor of the voice coil linear motor penetrates through the adapter plate and then is connected with the bottom of the watercooling head module; a grating ruler is mounted on the voice coil linear motor; the grating ruler is fixed between two guide rails at the bottom of the voice coil linear motor and is attached to the motor rotor. According to the shutter device provided by the invention, the reciprocating motion of the device is controlled through the voice coil linear motor, and the precision is improved; and hightemperature generated by light source irradiation is reduced through the water cooling head module.

Description

technical field [0001] The invention relates to the technical field of shutter equipment, in particular to a shutter device. Background technique [0002] The shutter device can block or pass through the irradiation of visible light, X-ray or laser, and control the time and window size of visible light, synchrotron radiation light source (X-ray) or laser irradiation on the imaging device (camera, etc.), so it is widely used; industrial shutter, Basically divided into mechanical control and automatic control. Among them, the mechanical control shutter is also called the manual shutter, which needs to rely on manual opening or closing of the laser shutter; the automatic control shutter is a solution that can rely on the control terminal to remotely open or close the shutter. . At present, the shutter control method used by industrial lasers is usually manual. In the actual operation and processing process, the operator needs to be located near the light source equipment and ...
