Due to its unique operational flexibility, it has been widely used in industrial assembly, safety and explosion protection and other fields. As a complex system, the robotic arm has uncertainties such as parameter perturbation, external interference and unmodeled dynamics. Therefore, the modeling model of the robotic arm also has uncertainties. For different tasks, it is necessary to plan the motion trajectory of the robotic arm joint space.

[0003] Currently, flange bolts are often used to fix the robotic arm and base during assembly. This requires tightening multiple bolts during assembly, which is cumbersome and affects the efficiency of installation and disassembly. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a modular robotic arm that can be quickly assembled, solving the problem that the method of using flange bolts for fixed connection requires tightening multiple bolts for fixing during assembly, which is cumbersome and affects the efficiency of installation and disassembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular robotic arm that can be quickly assembled, comprising a base and a protective cover. The base has a square groove inside, and a robotic arm module is inserted and installed on the base. A fixing plate is connected inside the base, and grooves are provided on the inner walls of both sides of the base. An electric push rod is fixedly installed below the base, and a movable plate is connected to the movable end of the electric push rod.

[0006] The movable plate has guide grooves on both sides, and a hook plate is slidably connected to the movable plate through the guide grooves. A fixing block is connected to the robotic arm module, and a splicing column is connected to the bottom of the robotic arm module. Limiting grooves are opened on both sides of the splicing column, and a slot is opened on the wall of the limiting groove. Multiple positioning rods are connected to the protective cover, and fastening bolts are threaded onto the protective cover.

[0007] As a further embodiment of this utility model: the fixing block is provided with a plurality of positioning holes, and threaded holes are provided on both the top and bottom of the fixing block. The positioning rod is inserted into the positioning hole, and the fastening bolt is threadedly engaged with the threaded hole.

[0008] As a further embodiment of this utility model: the base is connected to limit blocks on both sides, a sliding groove is provided below the base, the connection between the movable end of the electric push rod and the moving plate slides in the sliding groove, the moving plate slides in the square groove, and the limit blocks and the limit groove slide in cooperation.

[0009] As a further embodiment of this utility model: the fixing plate has notches on both sides, the notches and grooves are in the same position and have the same width, the hook plate is fitted into the groove, and one side of the hook plate is designed as a right triangle and fits into the slot.

[0010] As a further embodiment of this utility model: an I-shaped rod is connected below the hook plate, the middle part of the I-shaped rod slides in the guide groove, and the hook plate slides in the notch and comes into contact with the notch wall.

[0011] As a further embodiment of this utility model: the guide groove is designed to be skewed, and the two guide grooves together form a V-shaped structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This modular robotic arm, designed for rapid assembly, utilizes an electric push rod, a moving plate, a guide groove, a notch, a hook plate, and a locking slot. After the splicing column is inserted into the base, the operator activates the electric push rod to move the moving plate. As the moving plate moves, the tilted guide groove pushes the I-shaped rod, causing the hook plate to move. At this time, the groove and notch walls limit the hook plate, preventing it from rotating or tilting during movement. This allows the hook plate to move smoothly into the limiting groove, causing one end of the hook plate to engage with the splicing column, thus completing the installation of the robotic arm module. The operation is convenient and improves the efficiency of installation and disassembly.

[0014] This modular robotic arm, which can be assembled quickly, consists of a protective cover, a fixing block, a positioning rod, fastening bolts, positioning holes, and threaded holes. The operator can insert the positioning rod into the positioning hole to make one end of the protective cover fit into contact with the fixing block. Then, the operator can tighten the fastening bolts to make the fastening bolts threaded into the threaded holes, thereby fixing the protective cover and covering the clamping arm part of the robotic arm module, thus protecting the clamping arm part and reducing dust accumulation when not in use.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1-5 As shown, this utility model provides a technical solution: a modular robotic arm that can be quickly assembled, including a base 1 and a protective cover 2. A square groove 3 is provided inside the base 1. A robotic arm module 4 is inserted and installed on the base 1. A fixing plate 5 is connected inside the base 1. Grooves 6 are provided on the inner walls of both sides of the base 1. Notches 20 are provided on both sides of the fixing plate 5. The notches 20 and grooves 6 are positioned and have the same width. A hook plate 10 is fitted into the groove 6. One side of the hook plate 10 is designed as a right-angled triangle and fits into the slot 14. Through the fitting of the hook plate 10 and the groove 6, part of the hook plate 10 can slide into and be stored in the groove 6. The right-angled triangle design on one side of the hook plate 10 allows the hook plate 10 to hook onto the splicing column 12, preventing the splicing column 12 from moving up and down.

[0023] The base 1 is connected to limit blocks 19 on both sides, and a sliding groove 22 is provided under the base 1. The movable end of the electric push rod 7 and the connection point of the moving plate 8 slide in the sliding groove 22. The moving plate 8 slides in the square groove 3. The limit blocks 19 and the limit groove 13 slide together. Through the sliding cooperation between the limit groove 13 and the limit blocks 19, the workers can quickly complete the positioning and installation of the splicing column 12, so that the hook plate 10 can be aligned with the limit groove 13.

[0024] An electric push rod 7 is fixedly installed below the base 1. The movable end of the electric push rod 7 is connected to a movable plate 8. Guide grooves 9 are opened on both sides of the movable plate 8. The guide grooves 9 are skewed and the two guide grooves 9 form a V-shaped structure. Through the two skewed guide grooves 9 that form a V-shaped structure, when the movable plate 8 moves, the guide grooves 9 can push the I-shaped rod 21 to make the two hook plates 10 move in opposite directions, thereby clamping and hooking the splicing column 12.

[0025] The movable plate 8 is slidably connected to the hook plate 10 via the guide groove 9. The hook plate 10 is connected to the lower part of the I-shaped rod 21. The middle part of the I-shaped rod 21 slides in the guide groove 9. The hook plate 10 slides in the notch 20 and is in contact with the groove wall of the notch 20. Through the I-shaped structure of the I-shaped rod 21, the I-shaped rod 21 can slide smoothly in the guide groove 9, thereby preventing the I-shaped rod 21 from detaching from the guide groove 9.

[0026] A fixing block 11 is connected to the robotic arm module 4. The fixing block 11 has multiple positioning holes 17. Threaded holes 18 are provided on both the top and bottom of the fixing block 11. Positioning rods 15 are inserted into the positioning holes 17. Fastening bolts 16 are threaded into the threaded holes 18. A splicing column 12 is connected to the bottom of the robotic arm module 4. Limiting grooves 13 are provided on both sides of the splicing column 12. Slots 14 are provided on the groove walls of the limiting grooves 13. Multiple positioning rods 15 are connected to the protective cover 2. Fastening bolts 16 are threadedly connected to the protective cover 2. By inserting the positioning rods 15 into the positioning holes 17, it is convenient for workers to position and install the protective cover 2 and prevent the protective cover 2 from tilting.

[0027] The working principle of this utility model is as follows:

[0028] Workers slide the limiting block 19 into the limiting groove 13, allowing the splicing column 12 to be inserted into the base 1. Then, by activating the electric push rod 7, the moving plate 8 is moved. As the moving plate 8 moves, the skewed guide groove 9 pushes the I-shaped rod 21, causing the hook plate 10 to move within the notch 20. At this time, both the groove 6 and the groove wall of the notch 20 limit the hook plate 10, preventing it from rotating or skewing during movement. This allows the hook plate 10 to move smoothly into the limiting groove 13, causing one end of the hook plate 10 to engage with the slot 14. The hook plate 10 then hooks the splicing column 12, completing the installation of the robotic arm module 4. When idle, workers can insert the positioning rod 15 into the positioning hole 17 and tighten the fastening bolt 16, causing the fastening bolt 16 to be threadedly connected to the threaded hole 18, thereby fixing the protective cover 2 and protecting the clamping arm.
