[0008] Preferably, the positioning component includes multiple mounting brackets, which are respectively fixedly connected to one side of multiple upper and lower insert rods. Insertion strips are slidably connected to the mounting brackets. First positioning grooves are provided on both the upper and lower insert rods.

The bottom of the second connecting pipe is fixedly connected to a suction cup. A vacuum pump is fixedly installed on the connecting frame, and the adsorption end of the vacuum pump is fixedly connected to the adsorption shell.

[0011] Preferably, the top of the placement platform is fixedly connected to multiple support rods, each of which is located below a corresponding suction cup.

[0012] Preferably, the bottom of the connecting frame is fixedly connected to multiple connecting rings, each of which is rotatably connected to a movable rod.

[0015] A method for using a fully automated robotic arm in an automotive parts production line, the method comprising the following steps: Step 1: Place the car windshield to be assembled on the top of the placement platform. During the placement process, the windshield will press down on one end of the multiple support strips at the bottom by its own weight, causing the support strips to move downwards along the clearance groove. Through the fixed connection between the support strips and the connecting shaft, the connecting shaft will rotate along the rotating connection of the circular housing, and drive the ratchet to rotate synchronously. Step 2: The connecting frame is moved by the main body of the robotic arm, so that the connecting frame moves vertically downward and close to the top surface of the windshield. The top surface of the windshield is then attracted and fixed by the adsorption component. When the connecting frame moves downward, it drives multiple upper insertion rods to move downward synchronously and insert them into the corresponding upper insertion tubes. The limiting stop bar connected to the bottom of the upper insertion rod moves along the upper insertion tube into the circular housing and locks the ratchet. Step 3: Position the upper insert rod and its corresponding upper insert tube using the positioning component. At the same time, release the positioning between the lower insert rod and the lower insert tube using the positioning component. The main body of the robotic arm drives the connecting frame to move upward, and the positioning between the upper insert rod and the upper insert tube causes the circular shell and the support strip to move synchronously, thereby moving the windshield.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention utilizes the gravity of the windshield to compress the support strips for elastic displacement. Simultaneously, the mechanical arm drives the connecting frame to adhere and fix the windshield, while a limiting stop locks the ratchet, restricting the reverse movement of the support strips. This ensures that during windshield handling, one end of each support strip remains in contact with the bottom surface of the windshield. Furthermore, when the windshield is placed, the support strips can flexibly move and conform to the curvature of the windshield, reducing the impact of the windshield's curvature on the bottom surface support and improving the stability of the windshield during handling.

[0017] 2. During the contact process of the suction cup, the bottom of the suction cup tilts along the curved surface of the windshield, and drives the second spherical shell to slide and seal inside the first spherical shell, improving the adhesion between the suction cup and the top surface of the windshield and ensuring the effect of adsorption and fixation.

[0018] 3. By squeezing, the movable rod is flipped along the rotating connection of the connecting ring, which drives the second torsion spring to twist, thereby moving the wiping cotton along the windshield surface to make room and wipe. Before the suction cup contacts and adsorbs the windshield, the wiping cotton wipes the adsorption area of ​​the windshield in advance to prevent dust and impurities from affecting the adsorption stability.

[0021] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] like Figures 1 to 7The illustrated fully automated robotic arm for an automotive parts production line includes a base 1. A robotic arm body 2 and a placement platform 3 are fixedly connected to the top of the base 1. A connecting frame 4 is fixedly connected to one end of the robotic arm body 2. An adsorption assembly is located at the bottom of the connecting frame 4. Multiple circular housings 5 ​​are arranged on the side of the placement platform 3. An upper insertion tube 6 and a lower insertion tube 7 (e.g., ...) are fixedly connected to the top and bottom of each circular housing 5. Figure 7 As shown), a plurality of lower insert rods 8 are fixedly connected to the base 1. The top ends of the plurality of lower insert rods 8 are respectively inserted into the corresponding lower insert tubes 7. A plurality of upper insert rods 9 are provided on the side of the connecting frame 4. The number of upper insert rods 9 and lower insert rods 8 is the same as the number of circular shells 5. The internal rotating connection of the circular housing 5 is a connecting shaft 10 (e.g. Figure 6 As shown), a first torsion spring 11 is fixedly installed at the rotating connection of the connecting shaft 10 (as shown). Figure 3 and Figure 7 As shown), a ratchet 12 is fixedly connected to the connecting shaft 10, and a limit stop bar 13 is fixedly connected to the bottom end of the upper insertion rod 9. A relief groove 14 is opened on the side of the circular housing 5 near the placement platform 3. A support bar 15 is fixedly connected to the connecting shaft 10. One end of the support bar 15 extends upward along the corresponding relief groove 14 to the outside of the circular housing 5. Positioning components are provided on both the upper insertion rod 9 and the lower insertion rod 8, and a flipping component is provided between the upper insertion rod 9 and the connecting frame 4; The windshield to be assembled is placed on the top of the placement platform 3. During the placement process, the windshield presses down on one end of the multiple support strips 15 at the bottom by its own weight, causing the support strips 15 to move downward along the clearance groove 14 to make room. Through the fixed connection between the support strips 15 and the connecting shaft 10, the connecting shaft 10 rotates along the rotating connection of the circular housing 5, and drives the ratchet 12 to rotate synchronously. During the rotation of the connecting shaft 10, the corresponding first torsion spring 11 is twisted, so that the first torsion spring 11 is in a tightened state. Next, the connecting frame 4 is moved by the main body 2 of the robotic arm, so that the connecting frame 4 moves vertically downward and close to the top surface of the windshield. The top surface of the windshield is then fixed by the adsorption component. When the connecting frame 4 moves downward, it drives multiple upper insertion rods 9 to move downward synchronously and insert into the corresponding upper insertion tubes 6. The upper insertion rods 9 and the corresponding upper insertion tubes 6 are positioned by the positioning component. At the same time, the positioning component releases the positioning between the lower insertion rod 8 and the lower insertion tube 7. While the upper insertion rod 9 is inserted into the upper insertion tube 6, the limiting stop bar 13 connected to the bottom end of the upper insertion rod 9 moves along the upper insertion tube 6 into the circular housing 5 and locks the ratchet 12, preventing the support bar 15 from continuing to flip downward. Then, the robotic arm body 2 drives the connecting frame 4 to move upward, and the positioning between the upper insertion rod 9 and the upper insertion tube 6 makes the circular housing 5 and the support strip 15 move synchronously. The limiting stop bar 13 locks the ratchet 12, so that one end of the support strip 15 is always attached to the bottom surface of the windshield and supports it, preventing the windshield from falling during transportation. When applying glue and assembling the windshield, the upper insertion rod 9 is flipped by the flipping component, and the circular housing 5 and the support strip 15 are flipped synchronously, so that the support strip 15 is separated from the bottom surface of the windshield, ensuring the smooth progress of glue application and assembly. This invention utilizes the gravity of the windshield to compress the support strips 15 for elastic displacement. Simultaneously, the mechanical arm body 2 drives the connecting frame 4 to adsorb and fix the windshield, while the limiting stop bar 13 locks the ratchet 12, thereby restricting the support strips 15 from moving further downward. This ensures that during the handling of the windshield, one end of each support strip 15 remains in contact with the bottom surface of the windshield. Furthermore, when the windshield is placed, the support strips 15 can flexibly move and conform to the curvature of the windshield, reducing the impact of the windshield's curvature on the bottom support and improving the stability of the windshield during handling.

[0023] As a further embodiment of the present invention, the flipping assembly includes multiple sliding sleeves 16, all of which are fixedly connected to the side of the connecting frame 4. A slider 17 is slidably connected inside each sliding sleeve 16. A first electric cylinder 18 is fixedly installed on the sliding sleeve 16. The transmission shaft of the first electric cylinder 18 is fixedly connected to the top of the slider 17. A U-shaped frame 19 is fixedly connected to one side of each slider 17. A rotating shaft 20 is fixedly connected to the top of each of the multiple upper insertion rods 9. The multiple rotating shafts 20 are rotatably connected to the inside of the corresponding U-shaped frame 19. A swing hydraulic cylinder 21 is fixedly installed on the U-shaped frame 19. The piston shaft of the swing hydraulic cylinder 21 is fixedly connected to one end of the corresponding rotating shaft 20. After the upper insertion rod 9 is inserted into the upper insertion tube 6 and positioned, one end of the support strip 15 is attached to the bottom surface of the windshield. When the bottom surface of the windshield is coated with adhesive and assembled, the drive shaft of the first electric cylinder 18 moves downward, thereby driving the slider 17 to move downward synchronously inside the sliding sleeve 16, causing the upper insertion rod 9 to move downward and driving one end of the support strip 15 downward away from the windshield, ensuring that there is sufficient space for the support strip 15 to flip and make room between it and the windshield. Then, the piston shaft of the swing hydraulic cylinder 21 rotates, driving the rotating shaft 20 to rotate, causing the upper insertion rod 9 to flip synchronously with the rotating shaft 20 and driving the support strip 15 to move, thereby causing the support strip 15 to detach from the bottom surface of the windshield, preventing the support strip 15 from obstructing the coating and assembly of the windshield.

[0024] As a further embodiment of the present invention, the positioning component includes multiple mounting brackets 22, which are respectively fixedly connected to one side of multiple upper insertion rods 9 and lower insertion rods 8. Insertion strips 23 are slidably connected to the mounting brackets 22. First positioning grooves 24 are provided on both the upper insertion rods 9 and lower insertion rods 8. Insertion strips 23 are arranged opposite to the corresponding first positioning grooves 24. Second electric cylinders 25 are fixedly mounted on each mounting bracket 22. The drive shafts of the second electric cylinders 25 are fixedly connected to the corresponding insertion strips 23. Second positioning grooves 26 (e.g., ...) are provided on both the upper insertion tube 6 and lower insertion tube 7. Figure 7 (as shown) When the lower insertion rod 8 is inserted into the lower insertion tube 7, the insertion strip 23 on one side of the lower insertion rod 8 is inserted into the first positioning groove 24 and the second positioning groove 26 below, thereby positioning the lower insertion rod 8 inside the corresponding lower insertion tube 7. When the upper insertion rod 9 is inserted into the upper insertion tube 6, the insertion strip 23 on one side of the upper insertion rod 9 is moved by the corresponding second electric cylinder 25 and inserted into the first positioning groove 24 and the second positioning groove 26 above, thereby positioning the upper insertion rod 9 in the corresponding upper insertion tube 6. After the upper insertion rod 9 and the upper insertion tube 6 are positioned, the insertion strip 23 on one side of the lower insertion rod 8 is moved in the opposite direction by the corresponding second electric cylinder 25, so that the insertion strip 23 on one side of the lower insertion rod 8 moves away from the corresponding first positioning groove 24 and the second positioning groove 26, and releases the positioning of the lower insertion rod 8 and the lower insertion tube 7, thereby completing the positioning transfer, so that the upper insertion rod 9 can drive the upper insertion tube 6 and the circular shell 5 to move vertically upward, and the lower insertion tube 7 moves away from the lower insertion rod 8.

[0025] As a further embodiment of the present invention, a contact roller 27 is rotatably connected to one end of the support strip 15 near the placement table 3, and the contact roller 27 is made of rubber. When the windshield moves downward and approaches the support strip 15, the contact roller 27 at one end of the support strip 15 contacts the bottom surface of the windshield. As the support strip 15 moves to make way due to the pressure of the windshield's gravity, the contact roller 27 rolls along the bottom surface of the windshield. The rolling reduces friction during the contact process, and the rubber material of the contact roller 27 reduces rigid contact, thereby reducing the wear caused to the windshield by the bottom surface limit.

[0026] As a further embodiment of the present invention, the adsorption assembly includes an adsorption shell 28, which is fixedly connected to the bottom of the connecting frame 4. A plurality of first connecting pipes 29 are fixedly connected to the bottom of the adsorption shell 28. A first spherical shell 30 is fixedly connected to the bottom of each first connecting pipe 29. A second spherical shell 31 is slidably connected inside the first spherical shell 30. A second connecting pipe 32 is fixedly connected to the bottom of the second spherical shell 31. A suction cup 33 is fixedly connected to the bottom of the second connecting pipe 32. A vacuum pump 34 (e.g., ...) is fixedly mounted on the connecting frame 4. Figure 1 As shown), the adsorption end of the vacuum pump 34 is fixedly connected to the adsorption housing 28; The vacuum pump 34 creates a negative pressure inside the adsorption housing 28. When the connecting frame 4 approaches the top surface of the windshield, the bottoms of the multiple suction cups 33 contact the top surface of the windshield. Since the top surface of the windshield has a certain curvature, the bottom of the suction cups 33 tilts along the curvature of the windshield during the contact process, and drives the second spherical housing 31 to slide and seal inside the first spherical housing 30, thereby improving the adhesion between the suction cups 33 and the top surface of the windshield and ensuring the adsorption and fixation effect.

[0027] As a further embodiment of the present invention, a plurality of support rods 35 are fixedly connected to the top of the placement platform 3 (e.g., Figure 3 As shown), multiple support rods 35 are located below the corresponding suction cups 33; By setting a support rod 35 on the top of the placement platform 3, the top of the support rod 35 supports the bottom surface of the windshield. When the suction cup 33 contacts and adsorbs the top surface of the windshield, the support rod 35 and the suction cup 33 are positioned opposite each other, so that when the suction cup 33 contacts the top surface of the windshield, the corresponding position on the bottom surface of the windshield has a stable supporting force, ensuring that the suction cup 33 can successfully adsorb the windshield.

[0028] As a further embodiment of the present invention, a plurality of connecting rings 36 are fixedly connected to the bottom of the connecting frame 4, and a movable rod 37 is rotatably connected to each connecting ring 36. A second torsion spring 38 is fixedly installed at the rotatable connection between the connecting ring 36 and the movable rod 37. The movable rods 37 are all inclined. A wiping cotton 39 is fixedly connected to the bottom end of the movable rod 37. The plurality of wiping cotton 39 are respectively located below the corresponding suction cup 33. When the suction cup 33 approaches the top surface of the windshield, the wiping cotton 39 below the suction cup 33 first contacts the top surface of the windshield, and then, as the connecting frame 4 moves, it contacts and presses against the windshield. The pressing causes the movable rod 37 to flip along the rotating connection of the connecting ring 36, and drives the second torsion spring 38 to twist, thereby causing the wiping cotton 39 to move along the surface of the windshield to make room and wipe. Before the suction cup 33 contacts and adsorbs the windshield, the wiping cotton 39 wipes the adsorption position of the windshield in advance to prevent dust and impurities from affecting the adsorption stability.

[0029] As a further embodiment of the present invention, a plurality of circular cylinders 40 are fixedly connected to the side of the adsorption shell 28. An insertion hole 41 is provided on the circular cylinder 40. An arc-shaped pin 42 is fixedly connected to each of the movable rods 37. The arc-shaped pin 42 and the rotating connection of the movable rod 37 are coaxially arranged. When the movable rod 37 rotates along the rotating connection, causing the second torsion spring 38 to twist, the second torsion spring 38 reacts with the wiping cotton 39 through torque, causing the wiping cotton 39 to exert downward pressure on the top surface of the windshield, thus affecting the adsorption stability of the suction cup 33. By connecting the arc-shaped pin 42 to the movable rod 37, when the movable rod 37 rotates, the arc-shaped pin 42 moves synchronously with the movable rod 37 and slides into the corresponding insertion hole 41. When the vacuum pump 34 works to generate negative pressure inside the adsorption housing 28, the circular cylinder 40 generates negative pressure synchronously through communication with the adsorption housing 28, and adsorbs the arc-shaped pin 42 into the circular cylinder 40, thereby reducing the reaction force exerted by the wiping cotton 39 on the windshield and ensuring the stability of the suction cup 33 when adsorbing the windshield.

[0030] As a further embodiment of the present invention, a sealing ring gasket 43 is fixedly connected to the arc-shaped pin 42, and one end of the sealing ring gasket 43 is provided with an arc that fits the surface of the circular cylinder 40. When a negative pressure is generated inside the cylindrical cylinder 40 and the arc-shaped pin 42 is adsorbed, one end of the sealing ring gasket 43 contacts and adheres to the surface of the cylindrical cylinder 40 and seals the insertion hole 41 to prevent gas leakage between the insertion hole 41 and the arc-shaped pin 42 from affecting the adsorption of the suction cup 33.

[0031] A method for using a fully automated robotic arm in an automotive parts production line, the method comprising the following steps: Step 1: Place the car windshield to be assembled on the top of the placement platform 3. During the placement process, the windshield presses down on one end of the multiple support strips 15 at the bottom by its own weight, causing the support strips 15 to move downward along the relief groove 14 to make room. Through the fixed connection between the support strips 15 and the connecting shaft 10, the connecting shaft 10 rotates along the rotating connection of the circular housing 5, and drives the ratchet 12 to rotate synchronously. Step 2: The connecting frame 4 is moved by the main body 2 of the robotic arm, so that the connecting frame 4 moves vertically downward and close to the top surface of the windshield. The top surface of the windshield is then fixed by the adsorption component. When the connecting frame 4 moves downward, it drives multiple upper insertion rods 9 to move downward synchronously and insert into the corresponding upper insertion tubes 6. The limiting stop bar 13 connected to the bottom end of the upper insertion rod 9 moves along the upper insertion tube 6 into the circular housing 5 and locks the ratchet 12. Step 3: Position the upper insertion rod 9 and the corresponding upper insertion tube 6 using the positioning component. At the same time, release the positioning between the lower insertion rod 8 and the lower insertion tube 7 using the positioning component. Move the connecting frame 4 upward by the main body 2 of the robotic arm, and move the circular shell 5 and the support strip 15 synchronously by positioning the upper insertion rod 9 and the upper insertion tube 6, thereby moving the windshield.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.

10. A method of using a fully automated robotic arm for an automotive parts production line, applicable to the fully automated robotic arm for an automotive parts production line as described in any one of claims 1-9, characterized in that, The method includes the following steps: Step 1: Place the car windshield to be assembled on the top of the placement platform. During the placement process, the windshield will press down on one end of the multiple support strips at the bottom by its own weight, causing the support strips to move downwards along the clearance groove. Through the fixed connection between the support strips and the connecting shaft, the connecting shaft will rotate along the rotating connection of the circular housing, and drive the ratchet to rotate synchronously. Step 2: The connecting frame is moved by the main body of the robotic arm, so that the connecting frame moves vertically downward and close to the top surface of the windshield. The top surface of the windshield is then attracted and fixed by the adsorption component. When the connecting frame moves downward, it drives multiple upper insertion rods to move downward synchronously and insert them into the corresponding upper insertion tubes. The limiting stop bar connected to the bottom of the upper insertion rod moves along the upper insertion tube into the circular housing and locks the ratchet. Step 3: Position the upper insert rod and its corresponding upper insert tube using the positioning component. At the same time, release the positioning between the lower insert rod and the lower insert tube using the positioning component. The main body of the robotic arm drives the connecting frame to move upward, and the positioning between the upper insert rod and the upper insert tube causes the circular shell and the support strip to move synchronously, thereby moving the windshield.
