Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model.

[0018] like Figure 1 As shown, the robotic arm mainly consists of three parts: a slide table 1, a lifting platform 2, and a robotic arm 3.

[0019] The slide table 1 is equipped with a slide rail 4, which consists of two parallel tracks 41, providing stable guidance for the movement of the robotic arm. A motor 42 is mounted on one side of the track 41, and the front end of the motor 42 is connected to a lead screw 43. When the motor 42 starts, it drives the lead screw 43 to rotate. A slide block 44 is mounted on the track 41, which cooperates with the lead screw 43. When the lead screw 43 rotates, it drives the slide block 44 to move left and right on the track 41, thereby adjusting the horizontal position of the robotic arm.

[0020] An extension platform 2 is mounted on the slide 44 and connected to the slide 44 by a nut. This connection method is both stable and easy to adjust. When the height of the robotic arm needs to be adjusted, simply remove the nut and replace the extension platform 2 to raise or lower the robotic arm 3. The robotic arm 3 is mounted on the extension platform 2 and is also connected to the extension platform 2 by a nut, ensuring that the robotic arm 3 can be stably mounted on the extension platform 2.

[0021] The robotic arm 3 comprises four main parts: a drive unit 31, a first horizontal arm 32, a vertical telescopic arm 33, and a mechanical gripper 34. The drive unit 31 is the power source for the robotic arm, driving the first horizontal arm 32 to move in a circular motion around the drive unit 31, thereby achieving horizontal adjustment of the robotic arm. The vertical telescopic arm 33 is located at the front end of the first horizontal arm 32 and can move up and down under the control of a cylinder 35, thereby achieving vertical adjustment of the robotic arm. At the lower part of the vertical telescopic arm 33, a mechanical gripper 34 is installed. This mechanical gripper 34 is the actuator of the robotic arm, capable of gripping or releasing materials according to work needs. Furthermore, the mechanical gripper 34 can be replaced with different mechanical claws to adapt to different work tasks.

[0022] In order to further increase the working range of the mechanical arm 3, a second horizontal arm 36 is arranged at the front end of the first horizontal arm 32 in the embodiment. The second horizontal arm 36 can rotate horizontally around the front end of the first horizontal arm 32, so as to realize larger range adjustment of the mechanical arm. The vertical telescopic arm 33 is arranged at the front end of the second horizontal arm 36, so that the mechanical arm 3 is more flexible.

[0023] Specific use steps are as follows:

[0024] In use, the mechanical arm 3 can move left and right on the slide rail 4 to move along with the materials on the assembly line to carry out feeding and discharging operation, through the structural design of the slide base 1 and the slide rail 4. This design greatly improves the flexibility and efficiency of the production line. At the same time, the height of the mechanical arm 3 can be adjusted according to the height of the workpiece by arranging the adjustable height increasing table 2 on the slide base 44, so as to adapt to different height production lines and workpieces, and improve the compatibility of the mechanical arm 3 to different workpieces. In actual operation, the height of the height increasing table 2 and the mechanical arm 3 can be adjusted by simple nut connection, which is simple, stable and reliable. In addition, the multi-stage arm structure design and replaceable mechanical gripper 34 of the mechanical arm 3 also make the application adapt to more diversified work tasks and processing environments.

[0025] The above describes a feeding and discharging mechanical arm with a height-adjustable slide base in detail. The principles and implementation modes of the application are described by applying specific examples. The above embodiment is only used to help understand the method and core idea of the application. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the application without departing from the principles of the application, and these improvements and modifications also fall within the protection scope of the claims of the application.
