[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The present invention is further described in detail below in conjunction with the embodiments.

[0018] like Figure 1-4 As shown, a specific embodiment of a turnover box flexible clamping claw mechanism provided by the utility model:

[0019] A turnover box flexible clamp mechanism comprises a mounting frame 1, two guide rails 2 are fixed on the mounting frame 1, two clamping plates 3 are also arranged on the mounting frame 1, the two clamping plates 3 are slidably mounted on the two guide rails 2, and the lower end of the clamping plate 3 is provided with a flexible clamp;

[0020] The flexible clamping claw comprises a long box 4, which is fixed to the lower end of the clamping plate 3 by a plurality of bolts. A plurality of through holes are provided at the lower end of the clamping plate 3. One side of the long box 4 is open. A plurality of columnar clamping claws 6 are connected to the long box 4 by a plurality of springs 5. The columnar clamping claws 6 are arranged in a one-to-one correspondence with the through holes, and the columnar clamping claws 6 pass outward from the corresponding through holes.

[0021] A servo control system is also provided on the mounting frame 1. The servo control system is used to control the two clamping plates 3 to move toward each other on the two guide rails 2. The servo control system includes a servo motor and two sets of synchronous belt transmission mechanisms 7. The two sets of synchronous belt transmission mechanisms 7 are arranged side by side. The servo motor drives the two sets of synchronous belt transmission mechanisms 7 to work synchronously. One set of clamping plates 3 is connected to the synchronous belt above the synchronous belt transmission mechanism 7 through a first connecting member 8, and the other set of clamping plates 3 is connected to the synchronous belt below the synchronous belt transmission mechanism 7 through a second connecting member 9. Since the synchronous belt above the synchronous belt transmission mechanism 7 moves in opposite directions to the synchronous belt below, the servo control system can drive the two clamping plates 3 to move toward each other by connecting the two clamping plates 3 to the upper synchronous belt and the lower synchronous belt respectively, and the servo motor can be used as a driving synchronous belt transmission to drive the two clamping plates 3.

[0022] like Figure 5 As shown, the flexible clamping mechanism of the turnover box of this embodiment is installed on the robot arm 10 when in use. The program controls the robot arm 10 to move above the turnover box 11. Through the pre-set position, the robot arm 10 drives the flexible clamping mechanism to descend to a certain height, and then controls the operation of the servo motor through the pre-set clamping position and width, driving the two sets of synchronous belt transmission mechanisms 7 to move synchronously, so that the two clamping plates 3 move toward each other on the guide rail 2 under the drive of the synchronous belt, and then clamp the turnover box in the middle. The clamped position of the side of the turnover box has an uneven structure. After the part of the columnar clamping jaws 6 contacts the convex position, it retracts to the long box 4. The spring 5 is squeezed and compressed, while the part of the columnar clamping jaws 6 does not contact the convex position and does not retract. When the robot arm 10 drives the flexible clamping jaw mechanism to lift, the columnar clamping jaws 6 that have not retracted play a supporting role to prevent the turnover box from falling, and finally drive the turnover box to move.

[0023] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
