[0002] Robotic arms are the most widely used automated mechanical devices in the field of robotics. They can be found in fields such as industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. Although they vary in form, they all have one thing in common: they can receive instructions and accurately position themselves at a point in three-dimensional (or two-dimensional) space to perform operations. In fields such as automated logistics production, industrial robots are often needed to complete some processes such as grasping and sorting. Robot end effectors serve as the execution tools for robots to manipulate objects. In order for robots to accurately and stably grasp objects of different materials and shapes, different gripping suction cups are usually set at the robot's input end.

[0003] In the process of developing this utility model, the inventors discovered the following problems with the existing technology: 1. Existing robot suction cups are usually installed in a fixed connection manner, which makes it impossible to quickly replace the suction cup according to the user's needs. When different types of items need to be gripped and adsorbed, different robots need to be replaced, thus failing to meet people's usage needs; 2. During the disassembly and maintenance of existing robot suction cups, various auxiliary tools are required for disassembly, which is cumbersome, time-consuming, and labor-intensive. This not only increases the labor intensity of the staff but also significantly reduces the convenience of replacing and maintaining the suction cup, thus reducing work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a maintainable modular automatic gripping device for robots, which solves the problems mentioned in the background art. Existing robot suction cups are usually installed in a fixed connection manner, which makes it impossible to quickly replace the suction cups according to the user's needs. When different types of items need to be gripped and adsorbed, different robots need to be replaced. In addition, existing robot suction cups require a variety of auxiliary tools to disassemble and maintain, which greatly reduces the convenience of replacing and maintaining the suction cups and reduces work efficiency.

Slider blocks are mounted at both ends of each push plate. A fixed seat is mounted at the top of the mounting plate, and a second cavity is formed inside the fixed seat. Limit grooves are formed on the inner walls of the second cavity. Two moving blocks are mounted inside the second cavity, with limit blocks at both ends of each moving block. A spring is positioned between the two moving blocks, and a positioning pin is mounted on the side of each moving block away from the spring. An air pipe is mounted at the bottom of the mounting plate, and a suction cup is mounted at the bottom of the air pipe.

[0005] More preferably, the housing assembly includes an electric push rod, the bottom end of which is provided with a mounting base, the bottom end of which has a mounting groove, the two inner walls of which have slots, and the two inner walls of which have sliding grooves.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0016] Please see Figures 1 to 4This utility model provides a technical solution: a maintainable modular automatic gripping device for robots, including a housing assembly 1 and a mounting plate 2. The housing assembly 1 has a first cavity 3 at its inner top. The inner top of the first cavity 3 has two guide grooves 4. The inner walls of the first cavity 3 are provided with bidirectional threaded rods 5 via bearings. Two threaded blocks 6 are provided on the outside of the bidirectional threaded rods 5. Guide blocks 7 are provided at the top of the two threaded blocks 6. Connecting plates 8 are provided at the bottom of the two threaded blocks 6. One side of the two connecting plates 8 is connected to one end of a connecting rod 9, and the other end of the two connecting rods 9... Connected to the middle of one side of the push plate 10, the two push plates 10 are provided with sliders 11 at both ends. The top of the mounting plate 2 is provided with a fixed seat 12. The fixed seat 12 has a second cavity 13 inside. The two walls of the second cavity 13 are provided with limit grooves 14. The second cavity 13 is provided with two moving blocks 15. The two ends of the two moving blocks 15 are provided with limit blocks 16. The two moving blocks 15 are provided with a spring 17. The side of the two moving blocks 15 away from the spring 17 is provided with a positioning pin 18. The bottom of the mounting plate 2 is provided with an air pipe 19. The bottom of the air pipe 19 is provided with a suction cup 20.

[0017] In this embodiment, as Figure 1 As shown, the housing assembly 1 includes an electric push rod 101. The bottom end of the electric push rod 101 is provided with a mounting base 102. The bottom end of the mounting base 102 is provided with a mounting groove 103. The two inner walls of the mounting groove 103 are provided with slots 104. The two inner walls of the two slots 104 are provided with sliding grooves 105.

[0018] In this embodiment, as Figure 3 As shown, the internal dimensions of the slide 105 are consistent with the external dimensions of the slider 11; this increases the stability of the push plate 10 during movement and prevents the push plate 10 from shifting during movement.

[0019] In this embodiment, as Figure 4 As shown, the guide groove 4 and the guide block 7 are connected by a sliding connection; this increases the stability of the threaded block 6 during movement and prevents the threaded block 6 from rotating with the rotation of the bidirectional threaded rod 5 during movement.

[0020] In this embodiment, as Figure 2 As shown, the connecting plate 8 and the connecting rod 9 are symmetrical about the vertical center line of the mounting base 102 with respect to the push plate 10. This enables the mounting plate 2 to be quickly disassembled according to the user's needs, and makes the operation of the suction cup 20 during disassembly and maintenance easier, reducing the labor intensity of the staff, thereby greatly improving the convenience of the suction cup 20 during disassembly and maintenance and increasing the work efficiency of the suction cup 20 during maintenance and disassembly.

[0021] In this embodiment, as Figure 2As shown, the moving block 15 and the positioning pin 18 are symmetrical about the vertical center line of the mounting plate 2 with respect to the limiting block 16. This enables the suction cup 20 to be quickly replaced according to different types of gripped items, greatly improving the convenience of replacing the suction cup 20. It solves the problem of needing to replace different gripping robots when the types of gripped items are different, thus meeting the requirements of a maintainable modular automatic gripping device for robots.

[0022] In this embodiment, as Figure 3 As shown, the limiting groove 14 and the limiting block 16 are connected by a sliding connection; this makes the moving block 15 move in a single direction, avoiding the moving block 15 from tilting during movement, thereby improving the stability of the moving block 15 during movement.

[0023] The method of use and advantages of this utility model: When using this maintainable robot-mounted automatic gripping device, the working process is as follows: like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when installing the suction cup 20 according to different types of items, the fixing seat 12 at the top of the mounting plate 2 is inserted into the mounting groove 103. After the positioning pins 18 on both sides of the fixing seat 12 are resisted by the inner wall of the mounting groove 103, the two positioning pins 18 drive the moving block 15 to move into the second cavity 13 under the cooperation of the limiting groove 14 and the limiting block 16. At the same time, the two moving blocks 15 compress the spring 17. When the two positioning pins 18 move to the slot 104 opened in the inner wall of the mounting groove 103, the spring 17, using its own elastic structure, drives the positioning pins 18 through the moving block 15 to engage with the slot 104 under the cooperation of the limiting groove 14 and the limiting block 16, thus forming a locking structure between the positioning pins 18 and the slot 104. This allows for quick installation of the suction cup 20 according to different types of items, greatly improving the convenience of installing the suction cup 20. When the suction cup 20 needs to be disassembled and maintained, rotate the handle to drive the bidirectional threaded rod 5 to rotate. At this time, the bidirectional threaded rod 5 drives the two threaded blocks 6 to move in opposite directions with the cooperation of the guide groove 4 and the guide block 7. At this time, the two threaded blocks 6 drive the connecting rod 9 to move in opposite directions through the connecting plate 8. At the same time, the two connecting rods 9 drive the push plate 10 to move synchronously with the cooperation of the slider 11 and the slide groove 105. This causes the two push plates 10 to push the positioning pins 18 to move synchronously until the two positioning pins 18 disengage from the inside of the slot 104, and the locking structure between the positioning pins 18 and the slot 104 is released. This allows for quick disassembly of the mounting plate 2 according to the user's needs, and makes the operation of the suction cup 20 during disassembly and maintenance easier, reducing the labor intensity of the staff. This greatly improves the convenience of disassembly and maintenance of the suction cup 20 and increases the work efficiency of the suction cup 20 during maintenance and disassembly.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
