Description

Technical Field

[0001] This utility model relates to the field of pick-and-place mechanism technology, specifically to a dual-track conjugate cam pick-and-place mechanism. Background Technology

[0002] With the continuous advancement of intelligent manufacturing, the demand for automated equipment is increasing day by day. Among automated equipment, material transfer and handling structures are indispensable, so the pick-and-place mechanism is used very frequently.

[0003] Currently, most pick-and-place mechanisms use ordinary U-shaped tracks. When this type of U-shaped track mechanism is in operation, the drive motor needs to switch between forward and reverse rotation to switch the pick-and-place position. Due to the increased start-stop time of the motor's bidirectional rotation switching, the cycle time for the mechanism to complete one action is relatively long, making it unsuitable for high-speed applications. Utility Model Content

Detailed Implementation

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] like Figures 1 to 2 As shown, a dual-track conjugate cam pick-and-place mechanism includes a mounting base 4, a drive source, a cam component 3, a follower, and a guide assembly. The drive source is mounted on the mounting base 4 to provide rotational driving force. The cam component 3 is connected to the output end of the drive source and is driven to rotate by the drive source. The cam component 3 has at least two tracks. The follower has a follower part 10 adapted to the tracks and is connected to the guide assembly. The guide assembly is mounted on the mounting base 4 to guide the follower to move along a preset path. The follower or guide assembly has a clamping connector 13 for connecting to an external clamp. When the cam component 3 rotates, the follower part 10 cooperates with the tracks and is guided by the guide assembly, driving the clamping connector 13 to perform the pick-and-place action. The clamping connector 13, as a component connecting the follower or guide assembly to the external clamp, transmits the motion of the guide assembly and the follower to the external clamp, ultimately driving the clamp to complete the pick-and-place action. It is a connecting bridge between the mechanism's motion and the external clamp.

[0023] Mounting base 4 serves as the foundational load-bearing component of the entire mechanism, used to mount core components such as the drive source and guide components, providing a stable assembly benchmark for each component and ensuring the overall stability of the mechanism.

[0024] The cam component 3 is connected to the output end of the drive source and rotates under the action of the driving force. The at least two tracks set on its surface are the key guiding structures for realizing the movement of the mechanism. Through the cooperation of the tracks and the follower 10, its own rotational motion is converted into the composite motion of the follower. The cam component 3 is a conjugate cam track plate, and the tracks are two independent conjugate tracks.

[0025] In this embodiment, the follower 10 is embedded in the trajectory of the cam member 3, converting the rotational motion of the cam member 3 into its own linear or curvilinear motion. Simultaneously, the follower is connected to the guide assembly, moves along a preset path under the constraint of the guide assembly, and transmits the motion to the clamp connector 13, driving the external clamp to move. Specifically, the follower includes a first follower connecting plate 8, a second follower connecting plate 9, and a cam follower 10. The cam follower 10 is mounted on the follower connecting plate as the follower part 10, and the follower connecting plate is connected to the guide assembly.

[0026] The drive source provides continuous rotary driving force, driving the cam component 3 to rotate. Its core function is to provide power input to the mechanism through rotary motion, without the need for forward and reverse switching, reducing start-stop time to adapt to high-speed scenarios. Specifically, the drive source includes a motor 1 and a reducer 2. The motor 1 and reducer 2 are connected by a transmission. The reducer 2 is mounted on the mounting base 4. The cam component 3 is connected to the output end of the reducer 2. The motor 1 is a servo motor. The output end of the reducer 2 is equipped with a mounting flange, and the cam component 3 is fixed by the mounting flange.

[0027] In this embodiment, the guide assembly is mounted on the mounting base 4, and its main function is to provide precise guidance for the movement of the follower and constrain its movement direction. Specifically, the guide assembly includes an X-axis linear guide 6 and a Y-axis linear guide 7. The X-axis linear guide 6 is mounted on the mounting base 4, and the Y-axis linear guide 7 is connected to the X-axis linear guide 6 through a linear guide connecting plate 5. The follower is connected to the Y-axis linear guide 7. The X-axis linear guide 6, as a horizontal guiding base component, is fixedly mounted on the mounting base 4, providing a horizontal movement reference for the entire guide assembly. Through cooperation with the linear guide connecting plate 5, it constrains the Y-axis linear guide 7 and the connecting component to move linearly along the horizontal X-axis, ensuring the smoothness and accuracy of the movement in this direction and avoiding deviation or shaking. The Y-axis linear guide 7, acting as a vertical guide component, is connected to the X-axis linear guide 6 via the linear guide connecting plate 5. It is also connected to the follower (such as the connecting plate of the cam follower 10), providing vertical (Y-axis) motion guidance for the follower and subsequent connected fixture connector 13 and fixture. This constrains these components to perform linear motion in the vertical direction, ensuring the accuracy and stability of the vertical movement. The linear guide connecting plate 5, acting as a bridge between the X-axis linear guide 6 and the Y-axis linear guide 7, has the core function of achieving a rigid connection between the two guides. This allows the Y-axis linear guide 7 to move horizontally guided by the X-axis linear guide 6, while simultaneously providing vertical motion support for the follower. Through the connection of the linear guide connecting plate 5, the linear motion of the X-axis and Y-axis is combined into a composite motion, ensuring that the follower, driven by the cam component 3, can move stably along a preset horizontal + vertical composite path, ultimately driving the fixture to complete precise pick-and-place actions.

[0028] In addition, this mechanism also includes an origin positioning component, which includes an origin sensing plate 11 and an origin sensor 12. The origin sensing plate 11 is located on the cam component 3 or the rotating part of the drive source, and the origin sensor 12 is mounted on the mounting base 4 and cooperates with the origin sensing plate 11. The origin sensing plate 11, as a triggering element, is located on the rotating part of the cam component 3 (such as a conjugate cam track plate) or the rotating part of the drive source (such as a reducer 2), and rotates synchronously with these rotating parts. Through its own physical form, such as a protrusion of a specific shape or a blocking structure, it cooperates with the origin sensor 12 during rotation to provide a physical trigger signal for the detection of the origin position. The origin sensor 12, as a detection element, is fixedly mounted on the mounting base 4 (such as a mounting plate) and remains stationary. It senses the position change of the origin sensing plate 11: when the rotating origin sensing plate 11 passes the origin sensor 12, the sensor detects the presence of the sensing plate through photoelectric, electromagnetic, or other means, and then outputs an electrical signal to confirm that the mechanism is currently in the preset "origin position". The origin sensing plate 11 and the origin sensor 12 work together to realize the origin positioning function of the mechanism. By detecting the relative position of the two, the initial reference position of the cam component 3 and the drive source rotating component can be determined, providing a reference zero point for the motion control of the servo motor. This ensures that the mechanism can return to a uniform initial position every time it starts or resets, thereby guaranteeing the positional accuracy and motion consistency of the pick-and-place action and avoiding positioning deviations caused by accumulated errors.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
