Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically to a transfer robotic arm for SMT production lines. Background Technology

[0002] In surface mount technology (SMT) production lines, precise and efficient material transfer is crucial for ensuring production continuity and product quality. As the electronics manufacturing industry moves towards higher precision and automation, production lines are placing increasingly higher demands on the flexibility, coverage, and multi-angle operation capabilities of material transfer equipment.

[0003] Currently, traditional SMT production line transfer robotic arms mostly adopt integrated drive structures. Their rotating components and arm drive components often have mechanical linkage limitations, which severely restricts the rotation angle and the range of motion of the upper and lower arms. This structural defect often results in blind spots when the robotic arm faces multi-station, complex layout production lines, making it difficult to complete cross-area, multi-angle material grasping and transfer operations.

[0004] Meanwhile, due to the strong interrelationship of the drive components, adjustments or malfunctions of a single component can easily affect the overall operational accuracy, increasing maintenance costs and reducing the operational stability of the production line. Therefore, developing a robotic arm with a simple structure, where each drive component operates independently without angle limitations, and capable of large-scale, multi-angle material transfer, has become an important direction for solving the current material transfer challenges in SMT production lines. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a transfer robotic arm for SMT production lines. It has a simple structure, and the rotary component at the bottom and the drive components of the upper and lower arms are all independently set and have no angle limitation, which can cover material transfer operations in multiple ranges and angles.

[0006] To address the aforementioned technical problems, this utility model provides a transfer robotic arm for SMT production lines, comprising a base, a rotating frame at the center of the base, an external rotating gear inside the rotating frame, a rotating motor on the base, an internal rotating gear at the output end of the rotating motor adapted to the external rotating gear, a rotating housing connected to the outside of the external rotating gear, a large arm on the outside of the rotating housing, a small arm on the large arm, a mounting plate at the output end of the small arm, and a clamping assembly on the mounting plate.

[0007] Furthermore, a rotary motor is provided inside the rotary housing, and a first main bevel gear is provided at the output end of the rotary motor. The rotary housing and the boom are connected by a first shaft, and a first secondary bevel gear adapted to the first main bevel gear is provided on the first shaft.

[0008] Furthermore, a drive motor is provided on the inner side of the upper arm, and a second main bevel gear is provided at the output end of the drive motor. The upper arm and the forearm are connected by a second shaft, and a second driven bevel gear adapted to the second main bevel gear is provided on the second shaft.

[0009] Furthermore, auxiliary bearings and angle sensors are provided on both sides of the first shaft.

[0010] Furthermore, two removable protective shells are provided on the outer side of the upper arm.

[0011] Furthermore, a slewing bearing is provided between the slewing outer shell and the slewing frame.

[0012] The beneficial effects of this utility model are as follows: 1. High flexibility: The bottom rotary component and the drive components of the upper and lower arms are all independently set, with no angle restrictions between them. The rotary motor can drive the rotary components to achieve 360° rotation, and the drive components of the upper and lower arms can flexibly control the rotation angle, enabling the robotic arm to cover material transfer operations in multiple ranges and angles, and easily cope with complex SMT production line layouts and diverse material transfer needs.

[0013] 2. High stability: Each drive component is independent of the others. Failure or adjustment of a single component will not affect the operation of other components, which greatly improves the operational stability of the robotic arm, reduces production line downtime caused by component failure, and ensures the continuous and stable operation of the SMT production line.

[0014] 3. Easy Maintenance: The independent drive component design allows for quick location and replacement of faulty parts during maintenance and repair, reducing maintenance difficulty and cost, and improving maintenance efficiency. Attached Figure Description

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0024] Reference Figures 1 to 2 As shown, an embodiment of the present invention for a transfer robotic arm used in an SMT production line includes a base 1, a rotating frame 2 at the center of the base 1, an external rotating gear 3 on the inner side of the rotating frame 2, a rotating motor 4 on the base 1, an internal rotating gear 5 adapted to the external rotating gear 3 at the output end of the rotating motor 4, a rotating housing 6 connected to the outer side of the external rotating gear 3, a large arm 7 on the outer side of the rotating housing 6, a small arm 8 on the large arm 7, a mounting plate 9 at the output end of the small arm 8, and a clamping assembly 10 on the mounting plate 9.

[0025] Material Handling: When the SMT production line needs to transfer materials, the control system first starts the rotary motor 4, which drives the internal rotary gear 5 to rotate, thereby causing the external rotary gear 3 and the rotary housing 6 to rotate, adjusting the rotation angle of the upper arm 7 so that the upper arm 7 is aligned with the material location. Next, the drive component of the upper arm 7 is controlled to extend and rotate the upper arm 7 to a suitable angle. Then, the drive component of the lower arm 8 is controlled to adjust the angle of the lower arm 8, finally bringing the clamping component 10 mounted on the mounting plate 9 to the material handling position. Then, the clamping component 10 is controlled to move and handle the material, ensuring that the material is firmly clamped. Material transfer: After grabbing the material, the control system reverses the operation of the drive components of the upper arm 7 and the lower arm 8, causing the upper arm 7 and the lower arm 8 to retract and adjust their angles. At the same time, the rotary motor 4 is controlled to make the rotary housing 6 drive the upper arm 7 to rotate, transferring the material to the designated position. Material placement: When the material reaches the designated position, the control clamping component 10 releases the material, completing the material placement operation. Then, the control robotic arm returns to the initial position, waiting for the next material transfer task.

[0026] A drive motor 15 is provided on the inner side of the upper arm 7. A second main bevel gear 16 is provided at the output end of the drive motor 15. The upper arm 7 and the lower arm 8 are connected by a second shaft 17. A second driven bevel gear 18 that is adapted to the second main bevel gear 16 is provided on the second shaft 17. When the drive motor 15 is started, it drives the second main bevel gear 16 to rotate, which in turn drives the second driven bevel gear 18 that meshes with it to rotate, thereby driving the second shaft 17 to rotate, which in turn drives the lower arm 8 to rotate along the second shaft 17.

[0027] A rotary motor 11 is installed inside the rotary housing 6. A first main bevel gear 12 is installed at the output end of the rotary motor 11. The rotary housing 6 and the boom 7 are connected by a first shaft 13. A first driven bevel gear 14 that is adapted to the first main bevel gear 12 is installed on the first shaft 13. When the rotary motor 11 is started, it drives the first main bevel gear 12 to rotate, which in turn drives the first driven bevel gear 14 that meshes with it to rotate, thereby driving the first shaft 13 to rotate and thus driving the boom 7 to rotate along the first shaft 13.

[0028] The first shaft 13 is equipped with auxiliary bearings 19 and angle sensors 20 on both sides to monitor the rotation angle in real time; the outer side of the boom 7 is equipped with two detachable protective shells 21 to protect the boom 7 and the internal drive structure and ensure stable operation; a slewing bearing 22 is provided between the slewing shell 6 and the slewing frame 2.
