Description

Technical Field

[0001] The utility model relates to the technical field of roller brush component measuring machines, in particular to an optical end face radius measuring machine. Background Art

[0002] With the rapid development of society, sweeping robots are becoming more and more popular. However, the traditional brushes of sweeping robots are easy to get entangled with hair and scratch the ground. Therefore, a roller brush assembly (40) (colloid brush) has gradually emerged, wherein the roller brush assembly (40) includes a roller brush shaft and a roller brush rubber sleeve. The roller brush shaft is fixedly connected to the roller brush rubber sleeve through a sponge, and a plurality of long blades (4002) and short blades (4003) are arranged on the outer surface of the roller brush rubber sleeve at intervals. The left and right ends of the roller brush shaft on the roller brush assembly (40) usually reserve a section of shaft (end face (4001)) to adapt and assemble the roller brush assembly (40) on the sweeping robot. The sweeping robot drives the roller brush shaft to rotate through a motor to drive the roller brush assembly (40) to rotate, so as to drive the long blades (4002) and short blades (4003) on the roller brush rubber sleeve to clean the floor.

[0003] However, the reasons for measuring the long blades (4002) and the short blades (4003) are as follows: (1) If the blades on the roller brush rubber sleeve are too short, the garbage on the floor cannot be rolled up, which will cause the sweeping robot to not clean thoroughly; (2) If the blades on the roller brush rubber sleeve are too long, the blades will contact the floor over a large area, and the motor will have difficulty driving the roller brush assembly (40) to rotate, which will cause the sweeping robot to have excessive current, causing the sweeping robot to consume power quickly and generate noise, resulting in a poor user experience.

[0004] Therefore, after the roller brush assembly (40) is produced, not only the length of the end face (4001) of the roller brush assembly (40) must be measured, but also the radius of the long blade (4002) and the short blade (4003) on the roller brush rubber sleeve must be measured.

[0005] The problem of the above-mentioned prior art is: how to improve the automation level of measuring the end face length of the roller brush assembly and the radius of the long blade and the short blade on the roller brush rubber sleeve, so as to improve the measurement efficiency.
