Description

Technical Field

[0001] This invention belongs to the technical field of automotive parts processing equipment, and particularly relates to an automatic loading and unloading robot for automotive parts based on vision recognition. Background Technology

[0002] The vision-based automatic loading and unloading robot for automotive parts is an automated device that integrates industrial cameras, image recognition algorithms, and multi-axis robots. Through a vision system, it collects, locates, and identifies the position, posture, and model of parts in real time. Without manual positioning or special tooling, it can automatically complete actions such as precise gripping, transfer, loading to the processing station, and unloading and returning to the original position. It features high flexibility, adaptability to a variety of parts, high positioning accuracy, and fast response. It can effectively improve the automation level and production efficiency of automotive parts production lines and reduce manual intervention.

[0003] Because the base of the robotic arm is installed with screws, the vibration generated during the operation of the robotic arm acts on the screws, causing them to loosen. This results in a relatively short effective installation time for conventional robotic arm bases.

[0004] To address these issues, we propose a vision-based robotic arm for automated loading and unloading of automotive parts. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of the short effective installation time of conventional robotic arm bases, and to propose an automatic loading and unloading robotic arm for automotive parts based on vision recognition.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A vision-based automated loading and unloading robot for automotive parts includes a robot body. A mounting base is fixedly connected to the lower end of the robot body. A base is located at the lower end of the mounting base, and the base is in movable contact with the mounting base. A constraint block is fixedly connected to the corner of the base, and a threaded block and a spring-loaded clip are fixedly connected to the side of the base. A bolt is positioned between the constraint block and the threaded block, with the bolt threaded into the threaded block. The spring-loaded clip engages with the mounting base. When the mounting base is placed on the base, the spring-loaded clip engages with the mounting base. The bolt is then tightened into the threaded block, using the bolt to lock the spring-loaded clip and the mounting base in place. During vibration, the spring-loaded clip exerts a downward-sloping force on the bolt, preventing loosening and improving the durability of the effective mounting state.

[0007] Preferably, a reinforcing frame is fixedly connected to the upper part of the constraint block and the threaded block. The reinforcing frame increases the stress strength of the upper part of the constraint block and the threaded block.

[0008] Preferably, the base includes a first body and a bottom, with the lower end of the first body fixedly connected to the upper end of the bottom. The first body and the bottom are internally perforated with mounting holes. Expansion screws are passed through the mounting holes and installed on the ground.

[0009] Preferably, the constraint block includes a first block and a guide head. The lower end of the guide head is fixedly connected to the upper end of the first block, and the lower end of the first block is fixedly connected to the bottom. The guide head guides the mounting seat into the inner side of the first block, and the first block constrains the edges of the mounting seat, thereby improving the stability of the horizontal position of the mounting seat.

[0010] Preferably, the threaded block includes a second body, the upper part of which has a threaded groove, and the bolt is threadedly connected to the threaded groove. The lower end of the second body is fixedly connected to the base. The threaded groove guides the bolt's spiral.

[0011] Preferably, the spring clip includes a spring piece and a clip block, the clip block being fixedly connected to the spring piece, the upper part of the spring piece having a groove, and the lower end of the spring piece being fixedly connected to the bottom. The spring piece's elastic force acts on the clip block, which then engages with the mounting base. The groove accommodates the bolt. When the clip block is subjected to compressive force, the spring piece swings outward, causing the groove to exert a horizontal downward force on the bolt, preventing the bolt from falling off and facilitating the spring clip's fastening to the mounting base.

[0012] Preferably, the mounting base includes a second base body, the outer periphery of which has a fastening groove. The lower end of the second base body is in movable contact with the first base body, and the lower end of the robotic arm body is fixedly connected to the second base body. The fastening block engages with the fastening groove. The fastening block and fastening groove prevent the second base body from falling upwards.

[0013] In summary, the technical effects and advantages of this invention are as follows: 1. Place the mounting base on the base, so that the spring clip engages with the mounting base, tighten the bolt into the threaded block, and use the bolt to block the spring clip, so that the spring clip and the mounting base are locked. When vibrating, the spring clip exerts a downward force on the bolt, which prevents the bolt from loosening and improves the durability of the effective installation state.

[0014] 2. Use the guide head to guide the mounting base into the inner side of the first block, and use the first block to constrain the edges of the mounting base, thereby improving the stability of the horizontal position of the mounting base.

[0015] 3. The spring force of the spring plate acts on the fastener block, which is then fastened to the mounting base. The groove accommodates the bolt. When the fastener block is subjected to pressure, the spring plate swings outward, causing the groove to exert a horizontal downward force on the bolt, preventing the bolt from falling off and facilitating the spring clip to fasten the mounting base.

The spring piece 51 acts on the clip 53, and the clip 53 is fastened to the mounting base 6. The groove 52 accommodates the bolt 7. When the clip 53 is subjected to compressive force, the spring piece 51 swings outward, and the groove 52 exerts a horizontal downward force on the bolt 7 to prevent the bolt 7 from falling off.

[0025] like Figure 1 , 2 As shown in Figures 5 and 6, the mounting base 6 includes a second base body 61. A fastening groove 62 is formed on the outer periphery of the second base body 61.
