specific Embodiment approach 1

[0008] Specific implementation mode one: as Figure 1-10 As shown, the file automatic access manipulator with the force protection function described in this embodiment includes two fingers 1, a finger drive mechanism, a finger push-pull force sensor buffer structure, a photoelectric sensor 18, an RFID reader 19 and a tray 20. The finger driving mechanism includes a finger housing 2, a finger shaft 3, a finger clamping motor 7, an oval wheel 8, two follower wheels 9, a finger clamping spring 10, and a finger rotation motor 11; the finger push-pull force sensor buffer structure includes a buffer Spring 4, sliding sleeve guide post 5, push-pull force sensor 6, two sliding sleeves 12, finger seat 13, two guide rods 14, four linear bearings 15, outer sleeve 16 and spring plug 17; finger clamping motor 7 Drive the elliptical wheel 8 to rotate. Two follower wheels 9 are arranged on both sides of the ellipse wheel 8 and contact with the ellipse wheel 8 respectively. The centers of th...

specific Embodiment approach 2

[0009] Embodiment 2: The rotation angle of the driving finger housing 2 in this embodiment along the finger shaft 3 is -90°~+90°. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0010] Specific implementation mode three: as Figure 1-10 As shown, the tray 20 in this embodiment is provided with a tray guide post 20-1, and the tray 20 is installed on the bottom of the finger housing 2 through a constant force spring 21, so that the tray 20 is in a protruding state in a normal state. , when the protruding end face of the tray 20 touches an obstacle, it will retract into the bottom of the finger housing 2 . Other compositions and connections are the same as those in Embodiment 1 or 2.

[0011] Working principle of the present invention and the elaboration of working process:

[0012] Working process: firstly, the hand claw (the present invention) moves to the bookshelf where the file box is located, and inserts two fingers 1 into both sides of the file box 22 erected on the shelf at the same time, and then reads the information of the RFID code carrier at the spine of the file box to confirm Clamp the file box 22 after being correct and pull it out, put...

Abstract

An automatic file accessing mechanical arm with a force protection function relates to a file accessing device, belongs to the technical field of robots, and aims at achieving automatic accessing of classified or strictly confidential files. Fingers clamp an electric motor to drive an elliptic wheel to rotate; two driven wheels are arranged at two sides of the elliptic wheel and contact with the elliptic wheel respectively; centers of the two driven wheels are connected together through clamping of springs by the fingers; and the two fingers are adjusted to be close to or away from each other through change of center distance of the two driven wheels. A photoelectric sensor is used for detecting whether files exist in the two fingers, arranged between the two fingers, and mounted on a finger shell. A radio frequency identification device (RFID) reader-writer is arranged on the finger shell and used for reading RFID code carrying body information at spine positions of file boxes, and a tray is arranged under the two fingers in extensible mode and used for supporting the file boxes. The automatic file accessing mechanical arm with the force protection function is simple in structure, accurate to operate and suitable for remote manipulation, and is mainly used for automatic accessing of classified or strictly confidential files.

Description

technical field [0001] The invention relates to a file access device, belonging to the technical field of robots. Background technique [0002] Paper files are generally placed in file boxes and stored on the shelves of the file room, but confidentiality measures and strict management are generally adopted in the access process of confidential files or top-secret files. In order to keep secret, the management of confidential or top secret files needs to realize robot automatic access, which has become a development trend. However, in the prior art, there is no automatic equipment specially used for file access. Contents of the invention [0003] The purpose of the present invention is to provide a file automatic access manipulator with force protection function to realize the automatic access of confidential or top-secret files. [0004] The technical scheme that the present invention takes for solving the problems of the technologies described above is: [0005] The fi...
