The application relates to a mask adhesion test method. The test method comprises the following steps: placing a spacer on the surface of a substrate, so that the spacer covers part of the surface of the substrate. A test mask is prepared on part of the surface of the spacer, and the test mask extends to the exposed surface of the substrate. The test mask is completely separated from the substrate by applying force to the exposed part of the spacer, and the size of the force is tested. In the test method, a spacer is arranged between the substrate and the test mask, the spacer covers part of the surface of the substrate, and part of the surface of the spacer is exposed. The test mask is completely separated from the substrate by applying force to the exposed part of the spacer, and the size of the force is tested. In this way, the adhesion between the test mask and the substrate can be reflected by the size of the force, and the adhesion between the mask and the substrate can be tested.

This invention discloses a biomimetic surface for use in micro crawling robots and its preparation method, belonging to the field of biomimetic technology. It employs MEMS photolithography to prepare a silicon-based template and uses polydimethylsiloxane to replicate the structure to obtain the biomimetic surface for micro crawling robots. Based on the structure of a tree frog's foot, this invention prepares an anisotropic, high-friction biomimetic surface. Compared to a bare surface, this biomimetic surface has a 10-fold increased coefficient of friction. When this biomimetic plane is bonded to the leg structure of a micro robot, actual testing shows that the micro robot's maximum speed without the biomimetic plane can reach 25 times its body length per second, while with the biomimetic plane, its maximum speed can reach 50 times its body length per second or even higher, representing a 100% increase in speed and a significant performance improvement.

A flush glass system for a vehicle door is provided. The system includes a movable window, a trim panel, a seal, and a below belt member. The trim panel defines a first channel extending along a channel axis. The seal is partially mounted within the first channel with the seal including an exterior sealing lip at least partially, disposed between the movable window and the trim panel with the exterior sealing lip having an exposed surface to form a flush connection between an outer surface of the movable window and an exterior surface of the trim panel. The below belt member is formed separately from the trim panel with the below belt member defining a second channel extending along the channel axis. The movable window is disposed within the second channel prior to the first channel receiving the movable window to ease installation so as to reduce time during assembly.

This invention belongs to the technical field of five-axis machining centers, specifically an insulation device and method for a five-axis machining center cradle used in arc welding additive manufacturing. The device includes a turntable base, a worktable surface mounted on the upper surface of the turntable base, and an insulation mechanism mounted on the surface of the turntable base. This insulation mechanism directly insulates and separates the turntable base from the worktable surface. A maintenance mechanism is mounted at the lower end of the turntable base. The insulation device and method for this five-axis machining center cradle uses an insulation mechanism directly mounted on the turntable base and worktable surface. Insulation and heat insulation are achieved using an insulating pad within the insulation mechanism. A cleaning block with a mesh-like surface is installed on the exposed surface of the insulating pad, and air is blown into the cleaning block through a cleaning pipe to remove metal debris adhering to its surface. Simultaneously, the insulating pad is cooled by air, thus preventing any impact on the use of the insulation mechanism.
