[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Embodiment 1

[0025] Reference Figure 1-Figure 4 , a gripping mechanism, comprising a top plate 1 and four clamping blocks 8:

[0026] The four corners of the top plate 1 are designed to be arc-shaped to increase its structural strength and reduce damage from accidental collisions. Mounting holes are provided at the four corners of the top plate 1 to facilitate the installation of the mechanism to the corresponding equipment or frame. A rotating ring is fixed to the bottom of the top plate 1 to facilitate the rotation of the clamping block 8. The four clamping blocks 8 are all arranged below the top plate 1 and are designed to be arc-shaped to accommodate materials of different shapes and sizes.

[0027] The rotating mechanism includes a No. 2 motor 12, a worm 13, a worm wheel 14 and a connecting plate 15. The No. 2 motor 12 is fixed to the bottom of the top plate 1 by bolts, and its output shaft is fixedly connected to one end of the worm 13, and the other end of the worm 13 is rotatably connected to one side of the connecting plate 15. The top of the connecting plate 15 is fixedly connected to the bottom of the top plate 1, and the worm 13 and the worm wheel 14 are meshed with each other. The worm wheel 14 is fixedly sleeved with a rotating column, and one end of the rotating column is rotatably connected to the inner wall of the rotating ring at the bottom of the top plate 1. In this way, when the No. 2 motor 12 is working, it will drive the worm 13 to rotate, and then drive the worm wheel 14 and the rotating column to rotate, thereby realizing the rotation operation of the clamping block 8.

[0028] The lifting mechanism includes an electric telescopic rod 5 and a bottom frame 6. The fixed end of the electric telescopic rod 5 is fixedly connected to one end of the rotating column, and the telescopic end is fixedly connected to the top of the bottom frame 6. The shape of the bottom frame 6 is designed to be U-shaped, and the four clamping blocks 8 are all arranged below the bottom frame 6. In this way, when the electric telescopic rod 5 is extended or retracted, it will drive the bottom frame 6 and the clamping blocks 8 to rise or fall together, thereby realizing the lifting operation of the material.

[0029] The clamping mechanism is the core part of the automatic feeding and grabbing mechanism, which includes a No. 1 motor 7, a bidirectional screw rod 10, two sliding rods 11 and two moving blocks 9. The No. 1 motor 7 is fixed to one side of the bottom frame 6 by bolts, and its output shaft passes through one side of the bottom frame 6 and is rotatably connected to the bottom frame 6. The output shaft of the No. 1 motor 7 is fixedly connected to one end of the bidirectional screw rod 10, and the two ends of the bidirectional screw rod 10 are rotatably connected to the inner walls of the two sides of the bottom frame 6. The two ends of the two sliding rods 11 are also fixedly connected to the inner walls of the two sides of the bottom frame 6. The two moving blocks 9 are both threadedly sleeved on the bidirectional screw rod 10 and slidably sleeved on the sliding rod 11. In this way, when the No. 1 motor 7 is working, it will drive the bidirectional screw rod 10 to rotate, thereby causing the two moving blocks 9 to move toward or away from each other along the sliding rod 11. Since the four clamping blocks 8 are respectively fixedly connected to the bottom sides of the two moving blocks 9, the movement of the moving blocks 9 will drive the clamping blocks 8 to clamp or release.

[0030] The present application can be used in the fields of transportation and manufacturing, and can also be used in other fields suitable for the present application.

[0031] Embodiment 2

[0032] refer to Figure 1-Figure 4 , based on the improvement of the first embodiment, an automatic feeding and grabbing mechanism comprises:

[0033] In order to facilitate the protection and maintenance of the electrical components inside the mechanism, a shielding box 2 is also fixed at the bottom of the top plate 1. A box door is set on the front side of the shielding box 2 for easy opening for maintenance. A heat dissipation hole is opened on one side of the shielding box 2, and a filter 3 is fixed on the inner wall of the heat dissipation hole to prevent dust from entering. A controller 4 is fixed at the bottom of the shielding box 2 for controlling and operating the entire mechanism. The fixed end of the electric telescopic rod 5 extends through the round hole opened on the shielding box 2 to realize the lifting operation.

[0034] In order to facilitate the replacement or maintenance of the clamping block 8, a mounting plate 16 is fixed to the top of the four clamping blocks 8, and the mounting plate 16 is fixedly connected to the two sides of the bottom of the moving block 9 by bolts. In this way, when the clamping block 8 needs to be replaced or repaired, the clamping block 8 can be easily disassembled and installed by simply removing the bolts.

[0035] However, as is well known to those skilled in the art, the working principles and wiring methods of motor No. 1 7, motor No. 2 12, controller 4 and electric telescopic rod 5 are commonplace, and are all conventional means or common knowledge, and will not be elaborated herein. Those skilled in the art can arbitrarily select motor No. 1 7, motor No. 2 12 and electric telescopic rod 5 according to their needs or convenience, and connect them to controller 4 through lines, and supply energy through external power supplies and lines.
