Description

Technical Field

[0001] This utility model relates to the field of mechanical gripping technology, and in particular to a dual-grip drive device. Background Technology

[0002] In modern industrial automation and robotics, gripping devices are key components for tasks such as material handling, assembly, and sorting. Traditional gripping devices typically employ a single drive method, such as controlling the movement of a single gripping arm via pneumatic or electric means. However, this single drive method has some limitations, especially in applications requiring simultaneous gripping operations in different directions or with different forces.

[0003] In recent years, with technological advancements, dual-grip drive devices have gradually gained attention. These devices can control the movements of the upper and lower gripping blocks separately, enabling more flexible and precise gripping operations. Such devices have broad application prospects in various fields, such as automated production lines, logistics warehousing, and medical equipment.

[0004] While existing dual-grip drive devices have made some progress, they still have shortcomings in structural design and drive methods. For example, some devices have complex structures and high maintenance costs; others lack flexible drive methods and cannot meet diverse work requirements. In addition, traditional devices are prone to instability during the gripping process, affecting work efficiency and quality. Utility Model Content

[0005] This invention provides a simple, flexible, stable and reliable dual-grip drive device. By optimizing the internal structure design and drive method, it realizes independent drive of the upper gripping block and the lower gripping block, thereby improving the flexibility and accuracy of gripping operation.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a dual-grip drive device, including a housing, a drive motor installed in the housing, the output end of the drive motor being connected to a ⊥-shaped swing seat via an eccentric wheel, an upper gripping block and a lower gripping block being hinged to the top and bottom ends of one side of the ⊥-shaped swing seat respectively, the upper gripping block and the lower gripping block being connected to the ⊥-shaped swing seat via connecting blocks, one end of the upper gripping block and one end of the lower gripping block being rotatably connected to the housing, and the other end of the upper gripping block and the other end of the lower gripping block passing through the housing and extending to the outside of the housing.

[0007] As a further improvement of this utility model, one end of each of the two connecting blocks is hinged to the ⊥-shaped swing seat, the other end of one of the connecting blocks is hinged to the upper gripping block, and the other end of the connecting block is hinged to the lower gripping block.

[0008] As a further improvement of this utility model, both the upper gripping block and the lower gripping block are equipped with vibration motors.

[0009] As a further improvement of this utility model, a control board is installed on the top of the outer casing, and a storage battery is installed at the bottom of the inner casing.

[0010] As a further improvement of this utility model, the control board, the battery, the drive motor, and the two vibration motors are electrically connected.

[0011] The beneficial effects of this utility model are as follows: This utility model realizes the driving of the upper and lower gripping blocks through the linkage design of the drive motor and the eccentric wheel. Through the vibration motors of the upper and lower gripping blocks, gripping operations of different directions or forces can be performed simultaneously, which greatly improves the flexibility and precision of gripping operations. In application scenarios such as automated production lines, logistics warehousing and medical equipment, this flexibility can significantly improve work efficiency and quality.

[0016] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0017] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] This utility model provides the following: Figure 1-3 The dual-grip drive device shown includes a housing 1, a drive motor 2 installed inside the housing 1, and an eccentric wheel connecting the output end of the drive motor 2 to a ⊥-shaped swing seat 3. An upper gripping block 4 and a lower gripping block 5 are respectively hinged to the top and bottom ends of one side of the ⊥-shaped swing seat 3. Both the upper gripping block 4 and the lower gripping block 5 are connected to the ⊥-shaped swing seat 3 through connecting blocks 6. One end of the upper gripping block 4 and one end of the lower gripping block 5 are rotatably connected to the housing 1, and the other ends of the upper gripping block 4 and the lower gripping block 5 pass through the housing 1 and extend to the outside of the housing 1.

[0020] like Figure 1 and Figure 3 As shown, in this utility model, one end of each of the two connecting blocks 6 is hinged to the ⊥-shaped swing seat 3, the other end of one connecting block 6 is hinged to the upper gripping block 4, and the other end of the other connecting block 6 is hinged to the lower gripping block 5. Both the upper gripping block 4 and the lower gripping block 5 are equipped with vibration motors 7.

[0021] In this utility model, a control board 8 is installed on the top of the outer shell 1, and a storage battery 9 is installed at the bottom inside the outer shell 1. The control board 8, the storage battery 9, the drive motor 2, and the two vibration motors 7 are electrically connected.

[0022] Working Principle: In practical implementation, the control board 8 controls the start of the drive motor 2, and the output end of the drive motor 2 drives the eccentric wheel to rotate. The rotational motion of the eccentric wheel is converted into the swing motion of the ⊥-shaped swing seat 3. Since the upper gripping block 4 and the lower gripping block 5 are respectively hinged to the top and bottom ends of the ⊥-shaped swing seat 3 through the connecting block 6, the swing motion of the ⊥-shaped swing seat 3 will drive the upper gripping block 4 and the lower gripping block 5 to perform gripping actions respectively. At the same time, the control board 8 can also control the start of the vibration motor 7 in the upper gripping block 4 and the vibration motor 7 in the lower gripping block 5, so that the upper gripping block 4 and the lower gripping block 5 will vibrate during the gripping process, thereby enhancing the stability and accuracy of gripping. This design enables the dual-grip drive device of this invention to perform gripping operations in different directions or with different forces at the same time, greatly improving the flexibility and efficiency of gripping operations. In addition, the battery 9 provides power support for the entire device, ensuring that the device can work continuously and stably.
