Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and in particular to a gripper conveying mechanism. Background Technology

[0002] In automated production processes, grippers are needed to hold products for movement and transfer. Typically, this is done by cyclically rotating grippers. However, in actual use, the grippers need to rotate along a fixed path, but the effective gripping process is only a small segment of the movement path. During the remaining movement, the grippers need to maintain a fixed speed. For example, if several sets of grippers are set on a synchronous belt to transport products, when one set of grippers is working, another set of grippers waits synchronously. This results in waiting time, low work efficiency, and a significant waste of time. Existing technologies have room for improvement. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings by providing a gripper conveying mechanism, comprising two opposing mounting plates and a clamping station between the two mounting plates. A plurality of first and second grippers are movably disposed between the two mounting plates, rotating cyclically and sequentially entering the clamping station. A first drive shaft and a second drive shaft are rotatably disposed between the two mounting plates. The mounting plates are respectively provided with a first power source and a second power source to drive the first and second drive shafts to rotate, thereby causing the first and second grippers to cyclically rotate around the first and second drive shafts. A first synchronization component is provided on the first drive shaft to enable synchronous movement of all first grippers, and a second synchronization component is provided on the second drive shaft to enable synchronous movement of all second grippers.

[0004] Preferably, a speed reducer is provided at one end of the first drive shaft and the second drive shaft. The two speed reducers on the first drive shaft are connected to each other and the two speed reducers on the second drive shaft through a coupling. The first power is connected and driven through the power shaft and the speed reducer on the first drive shaft, and the second power is connected and driven through the power shaft and the speed reducer on the second drive shaft.

[0005] Preferably, the first synchronization component includes a first synchronization wheel disposed on the first drive shaft and rotating with the first drive shaft, and a second synchronization wheel movably disposed on the second drive shaft. A first synchronization belt is disposed on the outer periphery of the first synchronization wheel and the second synchronization wheel located on the same plane. The two ends of the first gripper are respectively fixedly disposed on the two first synchronization belts and rotate cyclically around the first drive shaft and the second drive shaft with the first synchronization belt.

[0006] Preferably, the second synchronization component includes a first synchronization wheel disposed on the second drive shaft and rotating with the second drive shaft, and a second synchronization wheel movably disposed on the first drive shaft. A second synchronization belt is disposed on the outer periphery of the first synchronization wheel and the second synchronization wheel located on the same plane. The two ends of the second gripper are fixedly disposed on the two second synchronization belts respectively and rotate cyclically around the first drive shaft and the second drive shaft with the second synchronization belts.

[0007] Preferably, the first synchronous pulley on the first drive shaft is located between the second synchronous pulleys, and the second synchronous pulley on the second drive shaft is located between the first synchronous pulleys.

[0008] Preferably, the second synchronous pulley is rotatably mounted on the first drive shaft and the second drive shaft via bearings.

[0009] Preferably, multiple support members are fixedly disposed between the two mounting plates.

[0010] Preferably, the first power source and the second power source are fixedly mounted on the mounting plate via connecting plates.

[0011] Compared with the prior art, this utility model uses a first power and a second power to drive the first drive shaft and the second drive shaft to rotate respectively. The first synchronization component and the second synchronization component drive the first gripper and the second gripper to move synchronously. The movement speed of the first gripper and the second gripper can be increased by increasing the rotation speed of the first power and the second power during the movement path of the first gripper and the second gripper, and the gripper can move quickly to the gripping station for the next gripping. This greatly reduces the interval between two adjacent gripping operations at the gripping station and effectively improves the processing efficiency. Attached Figure Description

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0020] like Figure 1-5 As shown, a gripper conveying mechanism includes two opposing mounting plates 1 and a gripping station 2 formed between the two mounting plates 1. Multiple support members 21 are fixedly arranged between the two mounting plates 1 to further enhance the overall structural strength. A first gripper 3 and a second gripper 4 are movably arranged between the two mounting plates 1, rotating cyclically and sequentially entering the gripping station 2. Two drive shafts 7 and 8, respectively located on opposite sides of the gripping station 2, are rotatably arranged between the two mounting plates 1. A first power source 9 and a second power source 10 are respectively provided on the mounting plates 1 to drive the first drive shafts 7 and 8 to rotate, thereby causing the first gripper 3 and the second gripper 4 to circulate around the first drive shafts 7 and 8. A first synchronization component 11 is provided on the first drive shaft 7 to move all the first grippers 3 synchronously, and a second synchronization component 12 is provided on the second drive shaft 8 to move all the second grippers 4 synchronously. The first power source 9 and the second power source 10 are fixedly mounted on the mounting plates 1 via connecting plates 22, and are motors. A reducer 13 is provided at one end of the first drive shaft 7 and the second drive shaft 8. The two reducers 13 on the first drive shaft 7 and the two reducers 13 on the second drive shaft 8 are connected by a coupling 14. The first power 9 is connected to the reducers 13 on the first drive shaft 7 through a power shaft 15, and the second power 10 is connected to the reducers 13 on the second drive shaft 8 through a power shaft 15. The first power 9 and the second power 10 drive the first drive shaft 7 and the second drive shaft 8 to rotate respectively. The first synchronization component 11 and the second synchronization component 12 drive the two first grippers 3 and the second grippers 4 to move synchronously. The first gripper 3 and the second gripper 4 can increase their moving speed by increasing the rotation speed of the first power 9 and the second power 10 during the movement path, and quickly move to the gripping station 2 for the next gripping, which greatly reduces the interval between two adjacent gripping operations at the gripping station 2 and effectively improves processing efficiency.

[0021] The first synchronization component 11 includes a first synchronization wheel 16 mounted on a first drive shaft 7 and rotating with the first drive shaft 7, and a second synchronization wheel 17 movably mounted on a second drive shaft 8. A first synchronization belt 18 is disposed around the outer periphery of the first synchronization wheel 16 and the second synchronization wheel 17, which are located on the same plane. The two ends of the first gripper 3 are respectively fixedly mounted on the two first synchronization belts 18 and rotate cyclically around the first drive shaft 7 and the second drive shaft 8 with the first synchronization belts 18. Four first grippers 3 are disposed on the first synchronization belt 18. The second synchronization component 12 includes a first synchronization wheel 16 mounted on the second drive shaft 8 and rotating with the second drive shaft 8, and a second synchronization wheel 17 movably mounted on the first drive shaft 7. A second synchronization belt 19 is disposed around the outer periphery of the first synchronization wheel 16 and the second synchronization wheel 17, which are located on the same plane. The two ends of the second gripper 4 are respectively fixedly mounted on the two second synchronization belts 19 and rotate cyclically around the first drive shaft 7 and the second drive shaft 8 with the second synchronization belts 19. Four second grippers 4 are disposed on the second synchronization belt 19. The first synchronous pulley 16 on the first drive shaft 7 is located between the second synchronous pulleys 17, and the second synchronous pulley 17 on the second drive shaft 8 is located between the first synchronous pulleys 16. The second synchronous pulley 17 is rotatably mounted on the first drive shaft 7 and the second drive shaft 8 via a bearing 20. The first power 9 drives two first drive shafts 7 to rotate. The first synchronous wheel 16, which is fixed on the first drive shaft 7, drives the second synchronous wheel 17, which is located on the same plane as the first synchronous wheel 16, to rotate on the second drive shaft 8 through the first synchronous belt 18. The second synchronous wheel 17 is rotatably mounted on the second drive shaft 8 through the bearing 20. The rotation of the second drive shaft 8 does not affect the second synchronous wheel 17. The two ends of the first gripper 3 move synchronously through the two first synchronous belts 18 located on the same side of the clamping station 2. The first power 9 drives the two first drive shafts 7 to rotate synchronously through the two reducers 13 to achieve synchronous movement of all the first grippers 3. Similarly, the second power 10 drives all the second grippers 4 to move synchronously. The first grippers 3 and the second grippers 4 are driven by the first power 9 and the second power 10 respectively. When one set of grippers is working, the other set of grippers can accelerate its movement to prepare for work. It has strong adjustability and high working efficiency.

[0022] like Figure 6As shown, clamping station 2 includes four positions A, B, C, and D. In the first step, the first gripper 3 is at position A, ready to enter the working state, and the second gripper 4 is at position C, ready to exit the working state. The first power source 9 and the second power source 10 have the same speed, and the first synchronous belt 18 and the second synchronous belt 19 move at the same speed. In the second step, the first gripper 3 and the second gripper 4 move downwards. When the first gripper 3 reaches position B, it is in the working state; when the second gripper 4 reaches position D, it exits the working state. The speed of the first synchronous belt 18, controlled by the first power source 9, remains constant, while the speed of the second synchronous belt 19, controlled by the second power source 10, accelerates, causing the second gripper 4 to rotate rapidly around the first drive shaft 7 and the second drive shaft 8 before entering position A. In the third step, the first gripper 3 moves to position C, ready to exit the working state, and the second gripper 4 is accelerated by the second power source 10 to position A, ready to enter the working state. At this time, the speeds of the first power source 9 and the second power source 10 are the same, and the speeds of the first synchronous belt 18 and the second synchronous belt 19 are the same. In the fourth step, the first gripper 3 enters point D and exits the working state, while the second gripper 4 enters the working state at point B. The first synchronous belt 18 accelerates its rotation, moving the first gripper 3 from point D to point A. When the first gripper 3 and the second gripper 4 are at points A, B, C, and D within the clamping station 2, their moving speeds are the same, as are the moving speeds of the first synchronous belt 18 and the second synchronous belt 19. When it is necessary to move from point D to point A, the moving speed is increased, significantly reducing the interval time between two adjacent clamping actions within the clamping station 2.

[0023] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications to the specification derived therefrom are still within the protection scope of this utility model.
