[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figure 1 and Figure 2 shown, the embodiment of the present invention aims to provide a multi-station cap-taking device, which includes a frame 1, a driving mechanism 3, a plurality of transmission mechanisms 4, and a plurality of execution mechanisms 5.

[0021] Among them, an arc-shaped guide groove 2 is provided on one side of the frame 1. The driving mechanism 3 is arranged on the frame 1. A plurality of transmission mechanisms 4 are all connected to the output shaft of the driving mechanism 3; under the action of the driving mechanism 3, the transmission mechanism 4 moves in the first direction; a plurality of execution mechanisms 5 are correspondingly connected to the transmission mechanism 4, and as the transmission mechanism 4 moves, the execution mechanism 5 moves in the arc-shaped guide groove 2 to realize the rotation of the end of the execution mechanism 5 facing away from the driving mechanism 3. The end of the execution mechanism 5 facing away from the driving mechanism 3 is used to connect a clamping cylinder or the like for performing the actions of taking and placing the bottle cap.

[0022] For the multi-station cap-taking device provided by the present invention, an arc-shaped guide groove 2 is provided on one side of the frame 1, the driving mechanism 3 is arranged on the frame 1, a plurality of transmission mechanisms 4 are all connected to the output shaft of the driving mechanism 3, and under the action of the driving mechanism 3, the transmission mechanism 4 moves in the first direction; a plurality of transmission mechanisms 4 are correspondingly connected to the transmission mechanism, and as the transmission mechanism 4 moves, the execution mechanism 5 moves in the arc-shaped guide groove 2 to realize the rotation of the end of the execution mechanism 5 facing away from the driving mechanism 3, so as to realize the action of one driving mechanism 3 driving a plurality of execution mechanisms 5, avoid using a plurality of driving devices, save energy and protect the environment, and reduce energy waste.

[0023] For the multi-station cap-taking device provided by the present invention, a single driving mechanism 3 reduces the number of energy conversion times in the transmission process, avoids the additional energy consumption caused by the synchronous control error of multiple driving mechanisms 3, and improves the energy utilization rate. A plurality of execution mechanisms 5 are linked with the driving mechanism 3 through the transmission mechanism 4, and can simultaneously perform operations such as grasping, rotating, or disassembling a plurality of bottle caps. When the execution mechanism 5 moves in the arc-shaped guide groove 2, the end of it facing away from the driving mechanism 3 will rotate along a preset arc track, and the required rotation angle is controlled by the distance that the execution mechanism 5 moves in the arc-shaped guide groove 2.

[0024] As Figure 3 and Figure 4As shown, in some feasible embodiments of the present invention, the actuator 5 includes a transmission connecting plate 51, a cam follower 52, a connecting shaft, and an actuator end 53. The transmission connecting plate 51 is connected to the transmission mechanism 4; the cam follower 52 is rotatably connected to the transmission connecting plate 51; and the cam follower 52 slides along the arc-shaped guide groove 2. One end of the connecting shaft is connected to the cam follower; the actuator end 53 is fixedly connected to the end of the connecting shaft facing away from the cam follower 52, and the actuator end 53 forms a cantilever, and the actuator end 53 extends into the working area. The actuator end 53 is connected to the cam follower 52 through the connecting shaft to form a cantilever structure, which can directly extend into the working area to use a clamping cylinder or other terminals to pick and place bottle caps up and down for operation, without an additional support structure. The transmission connecting plate 51 integrates the cam follower 52, the connecting shaft, and the actuator end 53 into an independent module, which is convenient for overall installation and disassembly. For example, when it is necessary to replace the actuator end 53 of different specifications, only the connection between the transmission connecting plate 51 and the transmission mechanism 4 needs to be loosened, and the module replacement can be quickly completed, saving maintenance time. Among them, an oil injection hole can be provided at the rotational connection between the transmission connecting plate 51 and the cam follower 52 for regular lubrication.

[0025] In some feasible embodiments of the present invention, the frame 1 includes mounting side plates 11, a mounting top plate 12, a mounting bottom plate 13, and a guide groove plate 14. The mounting side plates 11 are arranged in the first direction; the mounting top plate 12 is connected to the top of the mounting side plates 11; the mounting bottom plate 13 is connected to the bottom of the mounting side plates 11, that is, the mounting top plate 12 and the mounting bottom plate 13 are arranged opposite to each other, and are respectively located at the top and bottom of the mounting side plates 11. The top end of the guide groove plate 14 is connected to the mounting top plate 12 to Figure 1 Taking the direction shown as an example, the guide groove plate 14 is located at the rear side of the entire device. The bottom end of the guide groove plate 14 is connected to the mounting bottom plate 13, and an arc-shaped guide groove 2 is provided on the guide groove plate 14. The mounting side plates 11, the mounting top plate 12, and the mounting bottom plate 13 form a stable box-shaped structure, which improves the torsional stiffness compared with the traditional open frame. The top end of the guide groove plate 14 is connected to the mounting top plate 12, and the bottom end is connected to the mounting bottom plate 13 to form a rigid support in the vertical direction. When the actuator 5 slides in the arc-shaped guide groove 2, the deformation of the guide groove plate 14 is very small, avoiding movement jamming or angular deviation caused by the deformation of the arc-shaped guide groove 2. The space between the mounting top plate 12 and the mounting bottom plate 13 can be used to arrange the transmission mechanism 4 and the driving mechanism 3.

[0026] In some feasible embodiments of the present invention, the actuator 5 further includes a bearing support assembly 6 for supporting the connecting shaft. The bearing support assembly 6 supports the connecting shaft through high-precision bearings, controlling the radial runout within a certain range. During the process of the actuator end 53 rotating to pick up the cap, the accuracy can ensure that the force on the bottle cap is uniform, the capping torque fluctuation is small, and the damage or poor sealing of the bottle cap caused by eccentricity is avoided.

[0027] In some feasible embodiments of the present invention, it further includes a retaining belt assembly 7. The retaining belt assembly 7 is connected to the bearing support assembly 6. The retaining belt assembly 7 is movably arranged on one of the mounting side plates 11. The retaining belt assembly 7 is used to seal the cam follower 52 in a sealed space, which can effectively prevent external dust, water vapor and corrosive media from invading. Moreover, the sealed space shields the rolling noise of the cam follower 52. The retaining belt assembly 7 covers the transmission components, making the appearance of the equipment more concise and reducing the dead corners for dust accumulation. The retaining belt assembly 7 significantly extends the service life of key components such as the cam follower 52 through sealing protection, lubrication protection, structural enhancement and safety improvement.

[0028] As Figure 2 shown, in some feasible embodiments of the present invention, the transmission mechanism 4 includes a transmission shaft 41, a first pulley 42, a second pulley 43 and a synchronous belt 44. The transmission shaft 41 is connected to the output shaft of the drive mechanism 3; the first pulley 42 is arranged on the transmission shaft 41; the second pulley 43 is arranged on the frame 1; the synchronous belt 44 is wound around the first pulley 42 and the second pulley 43; and a transmission connecting plate 51 is connected to the synchronous belt 44. The flexible meshing characteristic of the synchronous belt 44 can absorb the vibration during the transmission process, reducing the operating noise of the equipment. The synchronous belt 44 transmission occupies a small space and can reduce the lateral dimension compared with the gearbox transmission. The synchronous belt 44 is usually made of polyurethane or neoprene and does not require lubrication, avoiding grease contamination of the product or the environment. The transmission mechanism 4 realizes synchronous drive of multiple workstations, space optimization and maintenance simplification through the high efficiency, accuracy and flexibility of the synchronous belt transmission. Its low noise, long life and overload protection characteristics significantly improve the reliability and economy of the equipment, especially suitable for high-speed and high-precision automated production lines.

[0029] In some feasible embodiments of the present invention, a tensioning assembly 8 is provided at the second pulley 43. The tensioning assembly 8 can automatically compensate for the elastic deformation and wear elongation of the synchronous belt 44. The limiting structure of the tensioning assembly 8 can prevent excessive tension, reducing the risk of fatigue fracture of the synchronous belt 44. The tensioning assembly 8 ensures that the synchronous belt 44 does not skip teeth during high-speed operation or frequent start-stop. Appropriate tension can reduce the lateral vibration of the synchronous belt 44 and reduce the noise caused by vibration.

[0030] In some feasible embodiments of the present invention, it further includes an anti-collision assembly (not shown in the figure). The anti-collision assembly and the retaining belt assembly 7 are arranged on the same mounting side plate 11. The anti-collision assembly usually adopts a polyurethane leather plug. When the position is abnormal, it will hit the polyurethane leather plug, resulting in an alarm and shutdown when the torque of the drive mechanism 3 exceeds the limit.

[0031] In some feasible embodiments of the present invention, it further includes a motor connecting plate 9, and the motor connecting plate 9 is connected to the driving mechanism 3. The motor connecting plate 9 adopts a high-precision processing technology, and the high installation station precision can ensure the accurate coaxial docking of the output shaft of the driving mechanism 3 and the transmission mechanism 4. This precision can avoid the vibration and noise caused by eccentricity, reduce the bearing wear, improve the transmission efficiency, and extend the service life.

[0032] In some feasible embodiments of the present invention, the plurality of transmission shafts 41 are connected by a coupling 45. The coupling 45 can compensate for axial deviation, radial deviation and angular deviation, and avoid transmission jamming caused by multi-shaft installation errors. The axial displacement generated by the change of thermal expansion load during the operation of the equipment can be absorbed by the elastic element of the coupling, preventing abnormal wear of transmission parts such as belt pulleys.

[0033] The multi-station lid-taking device provided by the present invention forms a frame 1 through the installation side plate 11, installation top plate 12, installation bottom plate 13 and guide groove plate 14. The heights of multiple frames are fixed, and the driving mechanism 3 is driven singly to drive the first belt pulley 42 to rotate, and then drive the synchronous belt 44 to move up and down, ensuring that multiple actuating mechanisms 5 can move synchronously. At the same time, in order to adapt to the component replacement in a space-compact working condition, the whole is divided into front and rear layers. The actuating end in the actuating mechanism 5 is connected by a bearing support assembly 6 to form a short cantilever, and extends into the working area to use a clamping cylinder and other terminals to pick and place materials up and down. The actuating end 53 is connected to a cam follower 52 through a transmission connecting plate 51 and moves up and down under the drive of the synchronous belt 44. The cam follower 52 drives the actuating end 53 to rotate in the arc-shaped guide groove 2 by using the cam relationship. The required rotation angle is controlled by the up and down movement distance of the bearing support assembly 6. Therefore, the calculation constraints for the material-taking position and the material-releasing position are required, and it can be adapted in all directions from 90° to 180°.

[0034] It should be noted that the user can set the speed of the driving mechanism 3 according to the use needs, and then control the movement speed of the cam follower 52 along the arc-shaped guide groove 2, so as to control the required position of the actuating end 53 and realize the positioning of multi-angle workstations.
