Abstract: Provided is a focusing assembly including a focusing barrel and a barrel retaining ring; the focusing barrel includes a first sleeve, a second sleeve, and a third sleeve that are sequentially sleeved from inside to outside of the focusing barrel; the first sleeve is provided with a lens mounting portion for mounting a focusing lens, a first end of the second sleeve is provided with a display screen mounting portion for mounting a display screen, a second end of the second sleeve is detachably connected to the barrel retaining ring, the first end and the second end being opposite ends of the second sleeve; and the lens mounting portion and the display screen mounting portion are configured such that the relative position thereof in a focusing direction of the focusing assembly is adjustable.

Abstract: Raw materials constituting a protective colloid includes: UV epoxy-modified acrylate polymer, heat-expandable particles, plasticizer, active monomer and cationic photoinitiator. A weight percent of the UV epoxy-modified acrylate polymer is 40-65%; a weight percentage of the heat-expandable particles is 2-10%; a weight percentage of the plasticizer is 10-15%; a weight percentage of the active monomer is 10-30%; and a weight percent of the cationic photoinitiator is 1-3%. Besides, a method for using the protective colloid is also disclosed.

Abstract: A method for a robot to automatically find a bending position, including the following steps: step 1, establishing a gripper tool coordinate system (TX, TY, TZ); step 2, determining a user coordinate system (XA, YA, ZA; XB, YB, ZB) of rear blocking fingers (11, 21); step 3, a robot gripper moving horizontally, and detecting the state of sensors (12, 22); step 4, the robot gripper executing a rotational movement, detecting the state of the sensors (12, 22), and thereby obtaining a standard bending position. The robot automatically finds the bending position, the teaching difficulty is reduced, and the bending quality is increased. In the elevator industry, elevator door plate bending sizes are the same, but forming sizes are different. In the present invention, only one product process needs to be taught in order to satisfy elevator door plate processing with different specifications, thereby reducing maintenance costs and increasing production efficiency.
