DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Embodiment 1

[0018] As Figures 1-3 shown, a multi-station bottle clamping mechanism proposed in this embodiment includes a clamping frame 2, a sliding rod 16 and a driving component. A chassis 3 is arranged at the bottom of the clamping frame 2. Two fixing frames a 10 and multiple fixing frames b 11 are slidably arranged on the clamping frame 2 and the chassis 3. A robotic arm 1 is rotatably connected to the clamping frame 2. The two fixing frames a 10 are respectively located on both sides of the multiple fixing frames b 11. Connecting pipes 14, middle suction discs 13 and multiple side suction discs 12 are communicated on both the two fixing frames a 10 and the multiple fixing frames b 11. The multiple connecting pipes 14 are all communicated with the suction component. A sliding pipe 17 is abutted between adjacent fixing frames a 10 and fixing frames b 11 or between adjacent two fixing frames b 11. A spring a 15 is arranged on the fixing frame a 10, and a spring b 18 is arranged inside the fixing frame b 11. The spring a 15 and the spring b 18 are in a compressed state for a long time. When the driving component releases and no longer abuts against the fixing frame a 10, the spring a 15 and the spring b 18 will push the fixing frame b 11 away from other fixing frames b 11 or the fixing frame a 10.

[0019] The sliding rod 16 is slidably arranged on the sliding tube 17, the fixing frame a10 and the fixing frame b11. The fixing frame a10, the sliding rod 16, the sliding tube 17, multiple groups of intermediate connecting components, the sliding tube 17, the sliding rod 16 and the fixing frame a10 are sequentially slidably connected. The intermediate connecting components include the sliding rod 16, the fixing frame b11 and the sliding rod 16 which are sequentially slidably connected. The sliding rod 16 is always in contact with the spring a15 or the spring b18; the driving component is arranged on the clamping frame 2 and the bottom frame 3, and the driving component is drivingly connected with the fixing frame a10 and the fixing frame b11.

[0020] The adsorption component includes a communicating block 4 arranged on the clamping frame 2. The top end of the communicating block 4 is communicated with an air pump 5, and the bottom plate of the communicating block 4 is communicated with a plurality of elastic hoses, and the plurality of elastic hoses are respectively communicated with a plurality of communicating pipes 14 in one-to-one correspondence.

[0021] When this embodiment is in use, the robotic arm 1 drives the clamping frame 2 and the bottom frame 3 to move to the position where the medicine bottles are located. The conveying component arranges the medicine bottles in a row. According to the diameter of the medicine bottles and the distance between adjacent medicine bottles, the worker controls the driving component to adjust the distance between two adjacent fixing frames b11 or between the fixing frame a10 and the fixing frame b11. Then, the intermediate adsorption disc 13 on the fixing frame a10 abuts against the bottle surface. During the process of abutting against the bottle surface, the side adsorption disc 12 rotates to a suitable angle. Then, the air pump 5 extracts the air between the intermediate adsorption disc 13, the side adsorption disc 12 and the bottle surface, so that the intermediate adsorption disc 13 and the side adsorption disc 12 fix the medicine bottle under the action of air pressure, so as to clamp medicine bottles with different diameters.

[0022] Embodiment Two

[0023] As Figure 2 and Figure 3 shown, a multi-station bottle clamping mechanism proposed in this embodiment, compared with Embodiment One, in this embodiment, a plurality of reset springs are arranged on both the fixing frame a10 and the fixing frame b11. The plurality of reset springs are respectively located at a plurality of side adsorption discs 12. The reset springs are located at the rotation axes of the side adsorption discs 12 rotating on the fixing frame a10 and the fixing frame b11. The reset springs are in contact with the side adsorption discs 12 and the fixing frame a10 or the fixing frame b11. Both the side adsorption disc 12 and the intermediate adsorption disc 13 are made of rubber material.

[0024] When this embodiment is in use, the air pump 5 blows a certain amount of gas into the side adsorption disc 12, so that the medicine bottle falls off onto the new conveying component. Then, the reset spring pushes the side adsorption disc 12 to reset, so that the side adsorption disc 12 can quickly clamp the next batch of medicine bottles, thus ensuring the clamping stability of the clamping mechanism.

[0025] Embodiment Three

[0026] AsFigures 1-3 As shown, a multi-station bottle clamping mechanism proposed in this embodiment. Compared with the first embodiment, in this embodiment, a multi-station bottle clamping mechanism is proposed. In this embodiment, the driving assembly includes a clamping frame 2 and a motor 6 on the bottom frame 3, a driving rod 7 rotatably arranged on the clamping frame 2 and the bottom frame 3, two rollers 8 arranged side by side on the clamping frame 2 and the bottom frame 3, a bolt 9 threadedly connected to each of the two rollers 8 and sliding relatively thereon, and two transmission belts arranged on the driving rod 7 and the two rollers 8. The driving rod 7 has a driving rod portion 71 and two actively distributed pulley portions 72 arranged side by side. The two transmission belts correspond to the two actively distributed pulley portions 72 and the two rollers 8 respectively.

[0027] In this embodiment, the motor 6 drives the driving rod 7 to rotate, the driving rod 7 drives the two rollers 8 to rotate, the rollers 8 drive the two bolts 9 to rotate relatively or away from each other. At the same time, the two fixing frames a10 are respectively abutted against the two bolts 9, and the distance between the two bolts 9 is stably increased or decreased, so as to automatically adjust the distance between the adjacent fixing frames a10 and the fixing frame b11, thereby improving the versatility of the mechanism.
