An in vitro trans-dermal diffusion apparatus for gas exposure, including: a gas generator, an exposure chamber, an exhaust treating device, a sampling arm, a diffusion chamber, a liquid replenishment tank, and a sample bottle rack. The in vitro trans-dermal diffusion apparatus for gas exposure supports multiple diffusion chambers conducting gas exposure experiments simultaneously. The sampling port and replenishing port of the diffusion chamber are separated, enabling the rapid replenishment of fluids through a replenishment tank after sampling, which reduces the time the skin membrane is separated from the receptor fluid. The sampling arm of the in vitro trans-dermal diffusion apparatus for gas exposure, combined with a telescoping rod, allows the sampling needle to be inserted into the sampling port for sampling and can also be extended into a sample bottle to release the sample, minimizing the contact between the sample liquid and the air.

This invention discloses a fully automatic roll-to-roll metal touch exposure device, belonging to the field of metal exposure technology. It includes a feeding mechanism for feeding metal raw materials, a working mechanism for exposing the metal roll on the feeding mechanism, and a winding mechanism for rewinding the exposed metal roll. The invention integrates a dust removal mechanism within the exposure chamber, consisting of an exhaust fan, a dust removal hood, an inner fixing frame, and a dust-adhesive roller. Before the raw material enters the exposure machine, the dust-adhesive roller physically brushes the metal surface, while the brushed dust is discharged in real time through the dust removal duct and the exhaust fan. This efficiently removes electrostatically adsorbed particles remaining after the protective film is peeled off, preventing tiny impurities from forming defects during exposure and improving the integrity of the exposed pattern and production yield.

This utility model relates to a light-shielding structure for an exposure machine, including an exposure machine body. An exposure chamber is fixedly connected to the front end of the exposure machine body. A square through-plate is disposed above the exposure chamber. Two extension plates are slidably connected to the inner wall of the square through-plate. A pressing plate is fixedly connected to one end of each extension plate, and a rubber pad is fixedly connected to one side of the pressing plate. Two fixing plates are fixedly connected inside the square through-plate. Two limiting grooves are formed on both the upper and lower surfaces of the square through-plate. Limiting sliders are slidably connected to the inner walls of the limiting grooves, and the limiting sliders are fixedly connected to the corresponding extension plates. A moving mechanism is disposed inside the square through-plate. This light-shielding structure for an exposure machine can block ultraviolet light inside the exposure chamber, preventing ultraviolet light from shining onto the human body surface during use and thus avoiding harm to health. It is quite practical.
