[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A robotic arm with positioning function includes a hanger 1. An electric slide rail 2 is horizontally arranged at the middle of the bottom end of the hanger 1. A movable part 3 is movably arranged at the bottom end of the electric slide rail 2. An electric slide rail 4 is vertically arranged on the front of the movable part 3. A positioning mechanism is arranged between the electric slide rail 4 and the hanger 1. The positioning mechanism includes a shaft frame 8. The shaft frames 8 are symmetrically arranged on both sides of the upper front end of the hanger 1. A lead screw 9 is movably arranged between the two shaft frames 8 through a bearing. A crank 10 is fixedly installed through the shaft frame 8 at the right end of the lead screw 9. A movable block 11 is movably arranged outside the lead screw 9. A positioning block 12 is fixedly installed on the front of the movable block 11. The positioning mechanism also includes a pressure sensor 13. The pressure sensor 13 is arranged on the upper right side of the electric slide rail 4. The pressure sensor 13 and the positioning block 12 are on the same horizontal line. A scale 14 is also provided on the front of the hanger 1.

[0025] In this embodiment, by setting a positioning mechanism, the position of the electric slide rail 2 4 in the horizontal direction can be adjusted more accurately. The operator can rotate the crank handle 10 to drive the lead screw 9 to rotate, so that the movable block 11 and the positioning block 12 can be moved to the predetermined position. Combined with the pressure sensor 13, accurate positioning is achieved, which effectively solves the problems of insufficient positioning accuracy and cumbersome positioning adjustment in the prior art.

[0026] like Figure 2 As shown, a lifting platform 5 is movably arranged on the front of the electric slide rail 2 4. A platform 6 is horizontally arranged on the front of the bottom end of the lifting platform 5. An electric gripper 7 is horizontally arranged below the platform 6. A disassembly and assembly mechanism is arranged between the platform 6 and the electric gripper 7. The disassembly and assembly mechanism includes a gear 15. The gear 15 is movably arranged inside the front end of the platform 6. An adjustment knob 16 is arranged on the upper part of the front end of the platform 6. The output shaft of the adjustment knob 16 is fixedly connected to the gear 15. A rack 17 is meshed at both ends of the gear 15. The disassembly and assembly mechanism also includes a fixing block 18. Fixing blocks 18 are arranged on both sides of the top middle part of the electric gripper 7. A positioning groove 19 matching the rack 17 is arranged at one end of the fixing block 18.

[0027] In this embodiment, the electric gripper 7 can be installed and disassembled conveniently and quickly through the cooperation of gear 15 and rack 17, which solves the problem of inconvenient installation and disassembly of electric gripper 7 in the prior art and improves the overall working efficiency and applicability of the robot.

[0028] Working Principle: Before operation, the electric slide rail 24 is positioned horizontally. The operator turns the crank handle 10, which drives the lead screw 9 to rotate. The rotation of the lead screw 9 causes the movable block 11 to move linearly along the lead screw 9, and the positioning block 12 installed on the front of the movable block 11 also moves accordingly. The operator can confirm the moving distance of the movable block 11 according to the scale 14 set on the front of the hanger 1, thereby adjusting the positioning block 12 to the predetermined position. Then, the electric slide rail 2 is activated, and the movable part 3 moves horizontally at its bottom end, driving the electric slide rail 24 installed on the front of the movable part 3 to move horizontally. During this process, the electric slide rail 24 will gradually approach the positioning block 12. When the pressure sensor 13 touches the positioning block 12, the electric slide rail 24 stops moving. At this time, the electric slide rail 24 has reached the predetermined position in the horizontal direction, completing the positioning. Afterwards, the electric slide rail 24 works, and the lifting platform 5 moves vertically in front of it, driving the platform 6 and the electric gripper 7 to move vertically to adjust to the appropriate height. To install the electric gripper 7, turn the adjusting knob 16 to rotate the gear 15. The rack 17, which meshes with both ends of the gear 15, moves in the opposite direction, aligning the fixing block 18 of the electric gripper 7 with the rack 17. The rack 17 then inserts into the positioning groove 19 of the fixing block 18 to complete the installation. To remove the gripper 7, turn the adjusting knob 16 in the opposite direction, and the rack 17 will disengage from the positioning groove 19. When the robot reaches the appropriate position and height, the electric gripper 7 will move to grasp and release objects, completing tasks such as material handling.
