Description

Technical Field

[0001] This invention relates to the field of spraying equipment technology, specifically to a multi-axis linkage spraying equipment for the R-angle of a power battery. Background Technology

[0002] UV coating for power batteries is a technology that uses UV-cured coatings to coat the surface of power batteries. Compared with traditional solvent-based coatings, UV coating has advantages such as environmental friendliness, high efficiency, and low energy consumption. The coatings used in UV coating are UV-cured coatings, which can cure rapidly under UV light, thus effectively shortening the production cycle and improving production efficiency. The coating thickness of UV coating is uniform and the adhesion is strong, which can effectively protect the surface of the power battery and improve the battery's weather resistance, corrosion resistance, and insulation performance. Since the coatings used in UV coating are water-based or UV-cured coatings and do not contain organic solvents, they are environmentally friendly and can reduce environmental pollution.

[0003] To address the aforementioned issues, patent application CN118142781A discloses a one-stop new energy power battery spraying device with paint recycling. This device features an intercepting ramp on a recycling chamber within the spraying compartment, and a storage trough with an internal scraping ramp that slides and rises within the intercepting ramp to facilitate paint recycling.

[0004] However, during the spraying process, the device can only spray the flat parts of the upper surface of the power battery. It cannot spray the parts with R-shaped chamfers evenly, which reduces the spraying effect of the device and cannot meet the production requirements well. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-axis linkage spraying device for the R-angle of a power battery to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] Example: Please refer to Figures 1-9 A multi-axis linkage spraying device for the R-angle of a power battery includes: a spraying frame 2 and a conveyor line 1, wherein the conveyor line 1 is located below the spraying frame 2, and a plurality of lifting fixtures 7 for fixing the power battery are detachably installed on the conveyor seat of the conveyor line 1; a spraying mechanism 3, installed below the spraying frame 2, for spraying the R-angle of the front and rear positions of the upper end face of the power battery; a steering mechanism 6, installed on the conveyor line 1, for adjusting the direction of the power battery; and a second spraying mechanism 4, consisting of a pair, both installed below the spraying frame 2, for spraying the R-angle of the left and right end faces of the power battery.

[0028] The working principle of this invention is as follows: In specific use, the power battery is first transported to the spraying mechanism 3 via the conveyor line 1. Then, the lifting fixture 7 is positioned by the positioning mechanism 5. Subsequently, the R-corner positions on both sides of the upper end of the power battery are sprayed by the spraying mechanism 3. After the spraying is completed, the positioning mechanism 5 cancels the positioning. Then, the power battery is transported again via the conveyor line 1. When the power battery moves to the spraying mechanism 4, the power battery is rotated 90° by the steering mechanism 6. Subsequently, the R-corner positions of the power battery are sprayed from the front and rear sides by a pair of spraying mechanisms 4.

[0029] As a further embodiment, the lifting fixture 7 includes a lifting base 71 inserted into a conveyor seat, a lifting fixing seat 72 fixed on the lifting base 71, a lifting turntable 75 rotatably mounted on the lifting fixing seat 72, a hollow lifting support rod 73 fixed on the lifting turntable 75, a lifting adsorption strip 732 fixed to the upper end of the lifting support rod 73, a lifting interface valve 731 installed on the lower half of the lifting support rod 73, the lifting interface valve 731 communicating with the hollow cavity of the lifting support rod 73, the lifting support rod 73 communicating with the vacuum adsorption chamber inside the lifting adsorption strip 732, and an adsorption hole opened at the upper end of the lifting adsorption strip 732, the adsorption hole communicating with the vacuum adsorption chamber. In this embodiment, an arc-shaped limiting groove 751 is provided on the lifting turntable 75, and a pair of limiting frames 76 are installed on the left and right sides of the upper end of the lifting base 71. A limiting spring telescopic rod 761 is installed on the opposite side of the limiting frame 76, and a limiting roller 762 is rotatably installed on the telescopic end of the limiting spring telescopic rod 761. The limiting roller 762 is inserted into the limiting groove 751.

[0030] The working principle of the lifting fixture 7 is as follows: When fixing the power battery, the power battery is placed on the lifting adsorption strip 732. Then, the lifting interface valve 731 is connected to an external air pump. The air pump is used to evacuate air, creating a negative pressure in the vacuum adsorption chamber, thereby adsorbing the power battery onto the lifting adsorption strip 732. Afterward, the lifting interface valve 731 is closed to complete the fixing work. By setting a limit spring telescopic rod 761 to push the limit roller 762 into the limit groove 751, the free rotation of the power battery can be effectively prevented, preventing the power battery from rotating during the transportation process and affecting the subsequent spraying work.

[0031] As a further embodiment, the spraying mechanism 3 includes a connecting seat 31 installed below the spraying frame 2. A lifting module 32 is installed on the connecting seat 31. A spraying box 33 is installed on the lifting end of the lifting module 32. A pair of spraying mounting seats 35 are installed at the lower end of the spraying box 33. Each spraying mounting seat 35 is equipped with a nozzle 37 via a rotating assembly. In this embodiment, the rotating assembly includes a locking bolt 36 threaded onto the spraying mounting seat 35. A spraying turntable 34 is rotatably installed on the locking bolt 36, and the nozzle 37 is installed on the corresponding spraying turntable 34.

[0032] The working principle of the spraying mechanism 3 is as follows: First, loosen the locking bolt 36 and then rotate the spraying turntable 34 to adjust the angle of the nozzle 37. After the adjustment is completed, tighten the locking bolt 36 to fix the spraying turntable 34. Then, the lifting module 32 drives the spraying box 33 to rotate, thereby adjusting the height of the nozzle 37 to better perform the spraying work. After the conveyor line 1 transports the power battery to the bottom of the spraying mechanism 3, start the nozzle 37 to spray the R-angle 413 on both sides of the front and rear of the upper end of the power battery.

[0033] As a further embodiment, the steering mechanism 6 includes a bogie 61 mounted on the conveyor line 1. A steering seat 62 is slidably mounted on the upper end of the bogie 61. A steering electric cylinder 64 is also mounted on the end of the bogie 61. The telescopic end of the steering electric cylinder 64 is fixedly connected to the steering connecting plate 63 at the lower end of the steering seat 62. A movable seat 65 is also slidably mounted on the steering seat 62. A steering rack 67 is mounted on the side of the movable seat 65 near the lifting fixture 7. A lifting gear ring 74 is also mounted on the lifting turntable 75. A movable electric cylinder 66 is also mounted on the upper end of the movable seat 65. The telescopic end of the movable electric cylinder 66 is fixedly connected to the end of the movable seat 65.

[0034] The working principle of the steering mechanism 6 is as follows: When steering, firstly, the movable electric cylinder 66 extends, pushing the movable seat 65 to move, thereby causing the steering rack 67 to approach and mesh with the corresponding lifting gear ring 74. Then, the steering electric cylinder 64 extends, pushing the steering seat 62 to move along the conveying direction of the conveyor line 1. At this time, the steering rack 67 can drive the lifting gear ring 74 to rotate, which in turn drives the lifting turntable 75 to rotate, thereby realizing the rotation of the power battery. When the telescopic end of the steering electric cylinder 64 extends to its farthest point, the power battery... The battery rotates 90°. Through the steering rack 67 and the lifting gear ring 74, the lifting fixture 7 can be limited, which can effectively prevent the power battery from rotating and improve the spraying effect. At this time, the left and right sides of the power battery are close to the corresponding spraying mechanism 2 4, which makes it convenient for the spraying mechanism 2 4 to spray the upper half R-angle of these two sides. After the spraying is completed, the steering electric cylinder 64 is reset, which drives the power battery to reset. Then the moving electric cylinder 66 retracts, which separates the steering rack 67 from the lifting gear ring 74, making it convenient for the conveyor line to transfer the lifting fixture 7 away.

[0035] As a further embodiment, the second spraying mechanism 4 includes a second connecting seat 41 installed at the lower end of the spraying frame 2. A transverse moving module 42 is installed at the lower end of the second connecting seat 41. A moving module 43 is fixed at the transverse moving end of the transverse moving module 42. A second lifting module 44 is installed at the moving end of the moving module 43. A second spraying mounting seat 45 is fixed at the lifting end of the second lifting module 44. An adjustment motor 46 is installed at the upper end of the second spraying mounting seat 45. The output end of the adjustment motor 46 passes through the second spraying mounting seat 45 and is fixed to an adjustment seat plate 47. An adjustment motor 48 is installed at the end of the adjustment seat plate 47. The output end of the adjustment motor 48 passes through the adjustment seat plate 47 and is fixed to a spraying seat 49. A second spray nozzle 40 is installed on the spraying seat 49. The adjustment seat plate 47 is L-shaped.

[0036] The working principle of the second spraying mechanism 4 is as follows: by adjusting the motor 46 to drive the adjustment base plate 47 to rotate, the spraying angle of the second nozzle 40 in the horizontal direction can be adjusted; by adjusting the motor 48 to drive the spraying base 49 to rotate, the spraying angle of the second nozzle 40 in the vertical direction can be adjusted.

[0037] During the actual spraying process, the power battery is rotated 90° by the steering mechanism 6. At this time, the left and right end faces of the power battery are close to the corresponding spraying mechanism 4 on the front and rear sides. Taking the spraying of the R-angle of the left end face as an example, the spraying angle of the nozzle 40 is adjusted by adjusting motor 46 in conjunction with adjusting motor 48 to meet the spraying requirements of R-angle 10. Then, the position of the nozzle 40 is adjusted by the horizontal moving module 42 in conjunction with the moving module 43. Then, the nozzle 40 is started. Then, the nozzle 40 is moved upward by the lifting module 44 to complete the spraying of R-angle 10 at the front position of the left end face.

[0038] Subsequently, by adjusting motor 1 46 in conjunction with adjusting motor 2 48, the spraying angle of nozzle 2 40 is adjusted to meet the spraying requirements of R angle 2 11. Then, nozzle 2 40 is started, and the horizontal movement module 42 drives nozzle 2 40 to move to the left, thus completing the spraying work of R angle 2 11.

[0039] Finally, by adjusting motor 46 in conjunction with motor 48, the spraying angle of nozzle 40 is adjusted to meet the spraying requirements of R-angle 12. Then, nozzle 40 is started, and the lifting module 44 moves nozzle 40 downward to complete the spraying of R-angle 12. At this time, the spraying of the three R-angles on the upper half of the left end face of the original power battery is completed. Similarly, the other spraying mechanism 4 can complete the spraying of the three R-angles on the upper half of the right end face of the original power battery.

[0040] By setting up spraying mechanism 3 in conjunction with spraying mechanism 4, the R-corner position of the power battery can be sprayed more effectively, improving the spraying quality and better meeting production needs.

[0041] As a further embodiment, the conveyor line 1 is also equipped with a positioning mechanism 5 for positioning the lifting fixture 7. The positioning mechanism 5 includes a positioning electric cylinder 51 hinged to the lower end of the conveyor line 1. The telescopic end of the positioning electric cylinder 51 is hinged to a positioning drive arm 52. A pair of positioning mounting seats 53 are installed on the front side of the conveyor line 1. A positioning rotating shaft 56 is rotatably mounted between the positioning mounting seats 53. The positioning rotating shaft 56 is fixedly connected to the positioning drive arm 52. A positioning swing arm 54 is also installed on the positioning rotating shaft 56. A positioning post 55 is installed at the upper end of the positioning swing arm 54. The positioning post 55 is slotted in the positioning groove on the front side of the lifting fixture 7.

[0042] The working principle of the positioning mechanism 5 is as follows: when the power battery is delivered to the designated position, the positioning electric cylinder 51 drives the positioning drive arm 52 to swing, thereby realizing the rotation of the positioning rotating shaft 56, and then inserting the positioning pin 55 on the positioning swing arm 54 into the corresponding positioning groove, thus completing the positioning of the lifting fixture 7, and thus realizing the positioning of the power battery.
