Description

Technical Field

[0001] The utility model relates to the technical field of electronic paper detection, in particular to a loading and unloading arm. Background Art

[0002] Electronic paper, also called digital paper, is an ultra-thin and ultra-light display screen, that is, it can be understood as a display screen as thin, soft and erasable as paper, and its display effect is close to that of natural paper, thus effectively avoiding reading fatigue. During the production process of electronic paper, it needs to be detected. During the detection process, in order to improve work efficiency, a robotic arm is usually used for handling. For example, the Chinese utility model patent with the publication number CN218674782U discloses a device for detecting surface defects of electronic paper, which includes a loading mechanism for real-time loading processing, a positioning mechanism for obtaining the electronic paper from the loading mechanism and placing it on the adsorption plate to push the electronic paper in real time, a detection mechanism for detecting the surface defects of the electronic paper through an industrial control computer, and a unloading mechanism for transferring the electronic paper that has completed the detection. A robotic arm is also provided between the loading mechanism and the unloading mechanism for grasping the electronic paper in real time. In the above-mentioned disclosed device for detecting surface defects of electronic paper, the electronic paper is transported from the loading mechanism to the detection mechanism and then from the detection mechanism to the unloading mechanism by a single robotic arm.

At the bottom of the second mounting bracket 203, there is an electric rotary table 204. The bottom of the electric rotary table is detachably connected with a loading component 205. The electric rotary table 204 can drive the loading component 205 to move along the X-axis, Y-axis and swing the loading component 205 to correct the deviation of the loading component 205. A buffer component 211 matched with the loading component 205 is arranged on the second mounting bracket 203.

Among them, the electric rotary table 204, the loading component 205 and the buffer component 211 are all in pairs. A pair of electric rotary tables 204 are both arranged at the bottom of the second mounting bracket 203 and are mirror-image arranged.

When in use, when the position of the slider 313 needs to be adjusted, first rotate the locking handle 312 to loosen the lead screw 306 from the open flange 311, and then rotate the rotating handle 309 to adjust the position of the slider 313. When the slider 313 reaches the predetermined position, finally rotate the locking handle 312 to lock the lead screw 306 with the open flange 311 to prevent the arm from shaking during movement, resulting in the displacement of the slider 313 from the predetermined position.
