The mobile frame 41 is connected to the first driving assembly in a transmission manner. The first pull rod 42 is rotatably installed on the mobile frame 41. One end of the first pull rod 42 is connected to the second driving assembly in a transmission manner. The second pull rod 43 is installed on one end of the first pull rod 42 away from the driving assembly. The first driving assembly drives the mobile frame 41 to move along the length direction of the first pull rod 42, and the second driving assembly drives the first pull rod 42 to rotate.

[0035] The mechanical arm for transporting files 50 in the technical solution of the utility model comprises a frame 10, a driving assembly and an access assembly. The frame 10 is provided with a storage chamber 11. The driving assembly comprises a first driving assembly and a second driving assembly both mounted on the frame 10. The access assembly comprises a mobile frame 41, a first pull rod 42 and a second pull rod 43. The mobile frame 41 is mounted on the frame 10 and is located in the storage chamber 11. The mobile frame 41 is connected to the first driving assembly in a transmission manner. The first pull rod 42 is rotatably mounted on the mobile frame 41. One end of the first pull rod 42 is connected to the second driving assembly in a transmission manner. The second pull rod 43 is mounted on an end of the first pull rod 42 away from the driving assembly. The first driving assembly drives the mobile frame 41 to move along the length direction of the first pull rod 42, and the second driving assembly drives the first pull rod 42 to rotate. When the mechanical arm is used to take the files 50, the first driving assembly drives the mobile frame 41 to move along the length direction of the first pull rod 42 to push the mobile frame 41. The first driving assembly then drives the first pull rod 42 to rotate to change the direction of the second pull rod 43, so that the file 50 is sandwiched between the second pull rod 43 and the moving frame 41, and then the first driving assembly drives the moving frame 41 to move inward, thereby driving the file 50 to the accommodating chamber 11 through the second pull rod 43; when the robot arm needs to place the file 50 in the accommodating chamber 11 at a predetermined position, it only needs to push the moving frame 41 out through the first driving assembly, and then drive the first pull rod 42 to rotate through the second driving assembly to make the second pull rod 43 deviate from the file 50, and then the first driving assembly drives the moving frame 41 and the first pull rod 42 to be recovered into the accommodating chamber 11, thereby completing the transportation of the file 50; compared with the technical solution of the prior art using a suction cup and a clamping claw, the technical solution of the utility model uses the second pull rod 43 to drive the file 50 to move, thereby greatly reducing the damage to the file 50 during the transportation process.

[0036] It should be noted that the damage to the file 50 during the transportation of the file 50 can be reduced by increasing the contact area between the second pull rod 43 and the file 50, such as setting the contact surface between the second pull rod 43 and the file 50 to a plane, or setting a flat plate on the side of the second pull rod 43 facing the file 50, thereby reducing the damage to the file 50 caused by the second pull rod 43 during the process of pulling the file 50.

[0037] In this embodiment, the access components are provided in plurality, and one access component is provided corresponding to one driving component. It can be understood that by providing a plurality of access components, the robot arm can simultaneously transport a plurality of files 50, thereby improving the working efficiency of the robot arm and the practicality of the files 50. It should be noted that the plurality of access components can operate simultaneously or separately, that is, a plurality of files 50 can be taken or pushed out at a time, or a single file 50 can be taken or pushed out at a time.

[0038] Specifically, the first driving assembly includes a first motor 21, a first transmission assembly and a screw rod 23. The first motor 21 is installed on the frame 10. The first transmission assembly is in driving connection with the output shaft of the first motor 21. One end of the screw rod 23 is installed on the first transmission assembly. The screw rod 23 is threadedly connected with the moving frame 41. The moving frame 41 is slidably connected with the frame 10. The first motor 21 drives the screw rod 23 to rotate through the first transmission assembly to drive the moving frame 41 to move along the length direction of the first pull rod 42. The transmission mode of the motor and the screw rod 23 has stable and reliable performance and is cheap, thereby improving the stability of the robot arm and reducing the production cost of the robot arm. Of course, in other embodiments, the first driving assembly can also be a cylinder, the output shaft of the cylinder is fixedly connected with the moving frame 41, and the cylinder drives the moving frame 41 to move.

[0039] Furthermore, one of the mobile frame 41 and the frame 10 is provided with a slide rail 12, and the other of the two is provided with a slide groove, and the mobile frame 41 is slidably connected by the cooperation of the slide rail 12 and the slide groove. By providing the slide rail 12 and the slide groove, the stability of the mobile frame 41 when driven by the first driving component to move is further improved, and the mobile frame 41 is prevented from deviating from the predetermined track; of course, in other embodiments, a slide bar can be fixed on the mobile frame 41, and a slide hole can be provided on the frame 10, and when the mobile frame 41 moves, the slide bar can slide in the slide hole.

One end of the transmission rod 33 is mounted on the second transmission assembly, and the transmission rod 33 is slidably connected to the moving frame 41. The transmission rod 33 is in transmission connection with the first pull rod 42. The second motor 31 drives the first pull rod 42 to rotate through the second transmission assembly and the transmission rod 33. The performance of the motor is stable and reliable, and the price is cheap.

[0041] Furthermore, the outer circumferences of the transmission rod 33 and the first pull rod 42 are respectively provided with a first gear 34 and a second gear 35, the first gear 34 and the second gear 35 are meshed with each other, and the transmission rod 33 and the first pull rod 42 are rotationally connected through the first gear 34 and the second gear 35. It can be understood that the first driving assembly will drive the moving frame 41 to move along the length direction of the first pull rod 42, and the moving frame 41 will also slide on the transmission rod 33, so the first gear 34 will slide on the transmission rod 33 with the moving frame 41, but the transmission rod 33 will drive the first gear 34 to rotate, so that the transmission rod 33 can drive the first pull rod 42 to rotate through the first gear 34 and the second gear 35. The transmission accuracy through the gears is higher and the price is lower, thereby reducing the production and manufacturing cost of the robot arm.

[0042] Specifically, the cross section of the transmission rod 33 is square, and the first gear 34 is provided with a sliding hole, and the transmission rod 33 is adapted to the sliding hole, so that the transmission rod 33 is slidably connected in the sliding hole, and the first gear 34 is rotatably connected to the moving frame 41. Therefore, the transmission rod 33 and the first gear 34 can slide along the length direction of the first pull rod 42, and the transmission rod 33 can also drive the first gear 34 to rotate; of course, in other embodiments, the cross section of the transmission rod 33 can also be a polygon, a five-pointed star or other irregular shapes, as long as it is non-circular.

[0043] In this embodiment, the first transmission assembly includes a first driving wheel 221, a first transmission belt 223 and a first driven wheel 222, the first driving wheel 221 is drivingly connected to the output shaft of the first motor 21, the first transmission belt 223 is sleeved on the first driving wheel 221 and the first driven wheel 222, and one end of the screw rod 23 is fixed to the first driven wheel 222; and / or the second transmission assembly includes a second driving wheel 321, a second transmission belt 323 and a second driven wheel 322, the second driving wheel 321 is drivingly connected to the output shaft of the second motor 31, the second transmission belt 323 is sleeved on the second driving wheel 321 and the second driven wheel 322, and one end of the transmission rod 33 is fixed to the second driven wheel 322.

[0044] In this embodiment, a guiding slope 421 is provided at one end of the first pull rod 42 away from the first driving assembly, and when the first driving assembly drives the first pull rod 42 to extend out of the accommodating cavity 11, the guiding slope 421 is arranged toward the accommodating cavity 11. By providing the guiding slope 421, the interference between the first pull rod 42 and the bag of the file 50 is reduced during the movement of the moving frame 41, and the wear of the bag of the file 50 during the movement of the first pull rod 42 is reduced.

[0045] Furthermore, the mechanical arm for transporting the file 50 further includes a guide plate 13, which is mounted on the frame 10 and located at the opening of the accommodating cavity 11. By providing the guide plate 13, the file 50 can slide into the accommodating cavity 11 along the guide plate 13 during the process of the second pull rod 43 pulling the file 50, thereby reducing the wear between the file 50 and the frame 10 during the process of the file 50 entering the accommodating cavity 11.
