Document Type and Number:
WIPO Patent Application WO/2023/046143
Kind Code:
A1
Abstract:
A conveying system (200) and a physical position-limiting device (100). The device (100) comprises: a first moving component (11); a guide rod (12) moving in the axial direction thereof, at least one stage of position-limiting groove (121) being formed in the outer surface of the guide rod (12), each stage of position-limiting groove (121) comprising first, second, and third sections of groove rail (121a, 121b, 121c) that are sequentially communicated, and the second section of groove rail (121b) being separately arranged at an angle with the first section of groove rail (121a) and with the third section of groove rail (121c); a safety rod (131), which has a first end inserted into the first section of groove rail (121a) and is configured to move relative to the guide rod (12) along the position-limiting groove (121); and a second moving component (14), connected to a second end of the safety rod (131) and configured to drive the safety rod (131) to rotate around the axial direction of the guide rod (12) by means of rotation, such that the first end of the safety rod (131) moves along the second section of groove rail (121b). According to the device (100), an operator can be reminded of a position-limiting critical point by means of touch, accurate information in physical positioning can be effectively fed back, and simple, efficient and accurate physical position-limiting is realized.
