[0008] Further improvement lies in that a cylinder protection cover is sleeved outside the telescopic cylinder, and one end of the cylinder protection cover is connected to the telescopic end of the telescopic cylinder.

[0009] Further improvement lies in that the cleaning mechanism includes an upper rack, a lower rack, a gear and a movable frame. There are two sets of upper racks, lower racks and gears correspondingly. The gear is rotatably installed on one side of the anti-spray baffle. The upper rack and the lower rack slide through the anti-spray baffle. The upper rack and the lower rack are respectively meshed with the upper and lower sides of the gear. The two sets of upper racks are respectively fixedly connected to the two sides of the upper end of the lens protection cover. The two ends of the movable frame are respectively arranged on the two sets of lower racks. A cleaning cloth is detachably installed on the movable frame.

[0010] Further improvement lies in that a spring telescopic rod is installed at the end of the lower rack. The movable frame is installed on the lower rack through the spring telescopic rod.

[0011] Further improvement lies in that sliding grooves are formed on both sides of the lens protection cover. Guide plates are fixedly connected to both sides of the lens protection cover. One end of the guide plate extends into the sliding groove. The guide plate divides the inside of the sliding groove to make the sliding groove into a C-shaped structure.

[0012] Further improvement lies in that one end of the guide plate close to the opening of the sliding groove is inclined downward.

[0023] Such as Figure 1As shown in the figure, a protective device for a laser coding lens includes a frame 1, on which a laser coding device 2 is installed. On one side of the lower end of the frame 1, a protective mechanism is provided, which is used to protect the laser coding device 2. The protective mechanism includes a telescopic cylinder 4 and a lens protective cover 5. The telescopic cylinder 4 is fixedly installed on the frame 1, and the lens protective cover 5 is installed on the telescopic end of the telescopic cylinder 4. The telescopic cylinder 4 drives the lens protective cover 5 to move. During coding, the lens protective cover 5 is moved out from under the laser coding lens, so that the laser coding lens is exposed for coding. When not coding, the lens protective cover 5 is moved to the lower side of the laser coding lens for shielding protection, reducing the contact between the laser coding lens and welding fumes during the welding process, and also preventing the laser from being accidentally emitted, causing unnecessary safety accidents, and improving the safety of laser coding.

[0024] A cylinder protective cover 6 is sleeved outside the telescopic cylinder 4, and one end of the cylinder protective cover 6 is connected to the telescopic end of the telescopic cylinder 4. The cylinder protective cover 6 moves along with the output end of the telescopic cylinder 4, protecting the output end of the telescopic cylinder 4 and improving the service effect of the telescopic cylinder 4.

[0025] Figure 4 、 5 As shown in the figure, a splash-proof baffle 3 is fixedly installed on the other side of the lower end of the frame 1. The splash-proof baffle 3 shields the laser coding lens from the side, and a cleaning mechanism is provided on the splash-proof baffle 3, which is used to clean the laser coding device 2. The cleaning mechanism includes an upper rack 7, a lower rack 8, a gear 9 and a movable frame 10. There are two sets of the upper rack 7, the lower rack 8 and the gear 9 respectively. The gear 9 is rotatably installed on one side of the splash-proof baffle 3. The upper rack 7 and the lower rack 8 slide through the splash-proof baffle 3. The upper rack 7 and the lower rack 8 are respectively meshed with the upper and lower sides of the gear 9. The two sets of upper racks 7 are respectively fixedly connected to the two sides of the upper end of the lens protective cover 5. The two ends of the movable frame 10 are respectively arranged on the two sets of lower racks 8, and a cleaning cloth 11 is detachably installed on the movable frame 10. By driving the lens protective cover 5 to move through the telescopic cylinder 4, the upper rack 7 moves along with it. Through the meshing action of the upper rack 7, the lower rack 8 and the gear 9, the lower rack 8 moves in the opposite direction as the upper rack 7 moves. The movement of the lower rack 8 drives the movable frame 10 to gradually approach the laser coding lens, and the cleaning cloth 11 cleans the laser coding lens, reducing the adhesion of soot on the laser coding lens.

[0026] As Figure 4 shown in the figure, a spring telescopic rod 12 is installed at the end of the lower rack 8. The movable frame 10 is installed on the lower rack 8 through the spring telescopic rod 12, and the spring telescopic rod 12 expands and contracts through the up and down movement of the movable frame 10.

[0027] As Figure 2 、 3As shown, sliding grooves 13 are formed on both sides of the lens protective cover 5. Guide plates 14 are fixedly connected to both sides of the lens protective cover 5. One end of the guide plate 14 extends into the sliding groove 13. The guide plate 14 divides the inside of the sliding groove 13 to make the sliding groove 13 into a C-shaped structure. The end of the guide plate 14 close to the opening of the sliding groove 13 is inclined downward, and the lowest point of the inclination is lower than the normal position of the movable frame 10. Through the guidance of the inclined end of the guide plate 14, the movable plate moves onto the guide plate 14 and enters the sliding groove 13 to slide. The spring telescopic rod 12 extends. The movable frame 10 is attached to the surface of the laser marking lens for cleaning through the supporting action of the guide plate 14. After moving to the other end of the sliding groove 13, the movable frame 10 separates from the guide plate 14. The movable frame 10 lacks the supporting action of the guide plate 14. The movable frame 10 moves downward to reset through the contraction of the spring telescopic rod 12. The movable frame 10 moves and resets under the guide plate 14, and the spring telescopic rod 12 is further compressed by the guide plate 14 and contracts further. After sliding out of the sliding groove 13, it returns to the initial state.

[0028] An airbag 15 is installed on the side of the anti-splash baffle 3 away from the laser marking device 2. The airbag 15 is made of elastic material. A nozzle 16 is installed at one end of the airbag 15. The nozzle 16 penetrates and extends to the other side of the anti-splash baffle 3. A pressing block 17 is installed on the lower rack 8. The pressing block 17 gradually moves with the lower rack 8 and gradually contacts the airbag 15. The pressing block 17 squeezes the airbag 15, and the airbag 15 blows air through the nozzle 16, so as to perform blowing and dust removal. After the pressing block 17 moves away from the airbag 15 with the lower rack 8, the airbag 15 restores to its original state due to its own elastic action.

[0029] A storage cover 18 is hinged to the side of the anti-splash baffle 3 close to the laser marking device 2. The storage cover 18 stores the movable frame 10, reduces the contact between the soot and the cleaning cloth 11 on the movable frame 10, and improves the cleanliness of the cleaning cloth 11. The storage cover 18 is rotationally connected to the anti-splash baffle 3 through a rotating shaft. A torsion spring is sleeved on the rotating shaft. A limit block is arranged on the upper side of the anti-splash baffle 3 to limit the flipping angle of the storage cover 18 through the limit block. A pressing block is arranged on the lower rack 8. The pressing block contacts one side of the storage cover 18 and moves and resets with the lower rack 8, pushing the storage cover 18 to flip downward to protect the movable frame 10. The lower rack 8 drives the movable frame 10 to move towards the laser marking lens, and the pressing block gradually separates from the storage cover 18. The storage cover 18 rotates on the rotating shaft under the action of the torsion spring; after the movable frame 10 moves and returns with the lower rack 8, the pressing block gradually contacts the storage cover 18 and pushes the storage cover 18 to flip downward and cover the upper side of the movable frame 10. A sticking roller is rotatably installed on the anti-splash baffle 3 on one side inside the storage cover 18. After the movable frame 10 drives the cleaning cloth 11 to move and be recycled into the storage cover 18, the cleaning cloth 11 contacts the sticking roller. The sticking roller rotates as the cleaning cloth 11 moves, and performs sticking and dust removal on the cleaning cloth 11, reducing the dust residue on the cleaning cloth 11 and improving the cleaning effect of the subsequent cleaning cloth 11.

[0030] During production, the bus parts are assembled onto the welding assembly fixture for welding. Before welding, the telescopic cylinder 4 pushes the lens protection cover 5 to move downward to the side of the laser coding lens to protect the laser coding lens, preventing welding spatter and dust from contaminating the laser lens. The upper rack 7 moves together with the lens protection cover 5. The upper rack 7 drives the lower rack 8 to move in the reverse direction through the gear 9. The lower rack 8 drives the movable frame 10 to move downward to the side of the laser coding lens. The movable frame 10 enters the sliding groove 13, is guided by the guide plate 14 and moves to the upper side of the guide plate 14. The movable frame 10 drives the cleaning cloth 11 to fit on the surface of the laser coding lens for wiping. When moving to the end of the sliding groove 13, the movable frame 10 drops under the action of the spring telescopic rod 12. Subsequently, when the lens protection cover 5 leaves from the lower side of the laser coding lens, the movable frame 10 slides out from the lower side of the sliding groove 13 along with the lower rack 8. When the movable frame 10 drives the cleaning cloth 11 to clean, the pressing block 17 also moves along with the lower rack 8. During the movement of the pressing block 17, it contacts the airbag 15 and gradually aligns to squeeze it. The airbag 15 is squeezed and blows air on the laser coding lens through the nozzle 16. After wiping with the cleaning cloth 11, it is blown again through the nozzle 16, further improving the cleaning effect. After welding is completed, the robot returns to the zero position after welding. The telescopic cylinder 4 pulls the lens protection cover 5 away from the lower side of the laser coding lens, and the laser coding device 2 performs coding. After coding is completed, the telescopic cylinder 4 drives the lens protection cover 5 to move downward to the side of the laser coding lens again for protection, improving production safety.
