Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a material handling device for automotive injection molded parts, including a rotating seat 4 and a robotic arm 5 located at the lower end of the rotating seat 4, with a chuck 6 installed on the robotic arm 5.

[0024] The rotating seat 4 is mounted on the base structure of the robotic arm 5. The robotic arm 5 drives the multi-joint arm to move through its own drive device, thereby achieving precise multi-degree-of-freedom movement and moving the end gripper 6 to the target position. The gripper 6 controls the opening and closing or deformation of the gripper fingers through its own cylinder or servo motor, and works with the robotic arm 5 to realize the picking, placing and transferring of automotive injection molded parts.

[0025] The top of the rotating seat 4 is provided with a guide seat 3, which is rotatably connected to the rotating seat 4. An adjustment component for controlling the rotation of the rotating seat 4 is provided at the connection between the guide seat 3 and the rotating seat 4. The rotating seat 4 is rotatably set at the lower end of the guide seat 3. By controlling the rotation of the rotating seat 4 through the adjustment component, the orientation of the robotic arm 5 can be adjusted, further increasing the flexibility of the robotic arm 5.

[0026] A hanging rail 1 is suspended above the guide seat 3. Two self-propelled mechanisms 7 are provided on the hanging rail 1. The hanging rail 1 is placed between the two self-propelled mechanisms 7. The left and right ends of the guide seat 3 are hinged to the self-propelled mechanisms 7.

[0027] Two self-propelled mechanisms 7 are respectively set at the left and right ends of the guide seat 3. They can provide dual drive support for the moving seat by sliding cooperation with the hanging rail 1, thereby improving the load-bearing capacity of the guide seat 3. The two ends of the guide seat 3 are hinged to the self-propelled mechanism 7, which allows a certain angle of relative rotation, ensuring that the guide seat 3 can perform small-amplitude turning and other operations along the hanging rail 1, thereby improving the material picking and placing range of the robotic arm 5.

[0028] It is worth explaining in detail that a transmission shaft 41 is provided between the guide seat 3 and the rotating seat 4. The lower end of the transmission shaft 41 is fixedly connected to the rotating seat 4, and the upper end of the transmission shaft 41 is rotatably connected to the guide seat 3.

[0029] The drive shaft 41 is rotated by an adjustment component, which in turn drives the rotating seat 4 to rotate, synchronously adjusting the direction of the robotic arm 5. Specifically, the adjustment component includes a first motor 31, a first gear 32, and a second gear 33. The first motor 31 is fixedly mounted at the lower end of the guide seat 3, and its output end is fixedly connected to the first gear 32. The second gear 33 is sleeved on the outside of the drive shaft 41 and is fixedly connected to it. The first gear 32 and the second gear 33 mesh. The first motor 31 controls the rotation of the first gear 32, which meshes with the second gear 33 during rotation, driving the drive shaft 41 to rotate. The drive shaft 41, in its rotation, completes the rotation control of the rotating seat 4.

[0030] Of course, in addition to motor gear drive, other rotary adjustment mechanisms can be used as alternatives, which will not be discussed in detail here. To prevent dust from adhering to the adjustment components during material handling, a dust cover that does not affect the rotation of the rotary seat 4 can be installed between the guide seat 3 and the rotary seat 4 to protect the adjustment components.

[0031] Regarding self-propelled organization 7:

[0032] The self-propelled mechanism 7 includes a sliding seat 71, a first connecting member 72, and a second connecting member 73. The second connecting member 73 is fixedly installed at both ends of the guide seat 3. One end of the first connecting member 72 is hinged to the second connecting member 73, and the other end of the first connecting member 72 is fixedly connected to the sliding seat 71. The top of the sliding seat 71 is provided with a track clamping groove 74, and the hanging rail 1 passes through the center of the track clamping groove 74. The track clamping groove 74 is provided with a guide wheel mechanism that cooperates with the hanging rail 1.

[0033] More specifically, the guide wheel mechanism includes two track wheels 75, which are rotatably mounted inside the track groove 74. The suspension rail 1 is placed between the two track wheels 75 and slidably connected to them. A second motor 76 is mounted on the top of the sliding seat 71, and the output end of the second motor 76 is fixedly connected to one of the track wheels 75. The second motor 76 controls the rotation of the track wheel 75, which pushes the sliding seat 71 to move along the suspension rail 1. The outer wall of the track wheel 75 has an annular groove that mates with the suspension rail 1. When the track wheel 75 rolls along the suspension rail 1, the left and right sides of the suspension rail 1 will be engaged in the annular groove, ensuring that the sliding seat 71 will not separate from the suspension rail 1.

[0034] It is worth explaining in detail that the top of the suspension rail 1 is provided with several suspension rods 2, which are fixedly connected to the suspension rail 1. The connection between the suspension rods 2 and the suspension rail 1 is provided with a track stiffener 11, which is integrally formed with the suspension rail 1. This can effectively enhance the local strength of the suspension rail 1, resist the deformation of the connection between the suspension rail 1 and the suspension rods 2, and improve the overall stability of the suspension rail 1.

[0035] The bottom of the hanging rail 1 has a groove 12. Without excessively affecting the structural strength of the hanging rail 1, the groove 12 at the bottom of the hanging rail 1 can provide a matching slot for installing accessories such as light strips, keeping the appearance clean by hiding the accessories. In addition, it can also reduce the overall weight of the hanging rail 1 and reduce the structural load on the hanging rod 2.

[0036] How this application works:

[0037] The rotating seat 4 is mounted on the base structure of the robotic arm 5. The robotic arm 5, through its own drive device, moves its multi-joint arm to move the end gripper 6 to the target position, realizing the picking, placing, and transferring of automotive injection molded parts. The rotating seat 4 is controlled to rotate by an adjustment component, adjusting the orientation of the robotic arm 5 and further increasing its flexibility. Two self-propelled mechanisms 7 are respectively located at the left and right ends of the guide seat 3. These mechanisms, through sliding cooperation with the overhead rail 1, provide dual-drive support for the moving seat, enhancing the load-bearing capacity of the guide seat 3. The two ends of the guide seat 3 are hinged to the self-propelled mechanisms 7, allowing for a certain angle of relative rotation, ensuring that the guide seat 3 can perform small-amplitude turning operations along the overhead rail 1, thus increasing the picking and placing range of the robotic arm 5.
