Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically a spraying device for a protective layer on the outer shell of a new energy vehicle battery. Background Technology

[0002] Battery casing protective layer spraying refers to coating a special material onto the surface of the battery casing to enhance the battery's durability, safety, and performance stability. This protective layer is usually applied to the battery casing by spraying. Different spraying technologies and materials can be used to meet the battery's needs in different working environments. According to a search, Chinese patent publication number CN222358672U discloses a new energy vehicle battery casing protective layer spraying device, which includes a spraying frame, a rotating door, and a storage tank. The storage tank is connected to the upper side of the spraying frame, and the rotating door is rotatably connected to the front left side of the spraying frame.

[0003] While the above technical solution can support and fix the inner side of the battery casing, preventing the battery casing clamping part from being missed and improving the overall effect of the protective layer coating, the spraying frame is fixedly installed at the bottom of the slider during use. The fixed structure of the spraying frame cannot be adjusted according to the different sizes of new energy vehicle battery casings. Excessive distance will affect the coating effect. Moreover, the spraying frame can only move in the horizontal direction, and the new energy vehicle battery casing cannot be adjusted, which will result in the problem that the left and right sides cannot be coated, thus affecting the practicality.

[0024] When in use, the operation of cylinder 3 can drive the protective cover 2 to rise and fall, making it convenient to pick up and put down the battery casing of new energy vehicles.

[0025] like Figure 1 and Figure 3As shown, a fixing mechanism for fixing the battery casing of a new energy vehicle is installed on the top of the base plate 1. The fixing mechanism includes a first motor 6 fixedly installed on the upper surface of the base plate 1. The output shaft of the first motor 6 is fixedly connected to a first frame 7. Two support rods 8 are symmetrically slidably connected inside the first frame 7. A top block 9 is fixedly connected to one side of each support rod 8. A second motor 10 is fixedly installed on one side of the outer surface of the first frame 7. The output shaft of the second motor 10 is fixedly connected to a bidirectional lead screw. The two support rods 8 are symmetrically threaded to the two ends of the bidirectional lead screw.

[0026] When fixing the battery casing of a new energy vehicle, the battery casing is placed on top of two support rods 8. Then, the second motor 10 rotates to drive the bidirectional lead screw to rotate. The screw can drive the support rods 8 on both sides to move relative to each other. With the help of the top block 9, it can be fixed from the inside of the battery casing. During the spraying process, the first motor 6 rotates to drive the battery casing to rotate, which facilitates the spraying of the other two sides of the battery casing and improves its practicality.

[0027] like Figure 1 and Figure 4 As shown, a spraying mechanism is installed inside the protective cover 2. The spraying mechanism includes a third motor 11 fixedly installed on one side of the outer surface of the protective cover 2. The output shaft of the third motor 11 is fixedly connected to a first one-way lead screw 12. The outer surface of the first one-way lead screw 12 is threadedly connected to a second frame 13 that is slidably connected to the top of the inner part of the protective cover 2. Both ends of the second frame 13 are fixedly connected to vertically arranged third frames 14. The interiors of the second frame 13 and the third frame 14 are slidably connected to second sliders 15. An electric push rod 16 is fixedly installed on one side of the second slider 15. One end of the electric push rod 16 is fixedly connected to a spray nozzle 17. A fourth motor 18 is fixedly installed on one side of the outer surface of the second frame 13 and the third frame 14. The output shaft of the fourth motor 18 is fixedly connected to a second one-way lead screw 19 that is threadedly connected to the second slider 15. A storage tank 20 and a delivery pump 21 are fixedly installed on the top of the protective cover 2. The input end of the delivery pump 21 is fixedly connected to the inside of the storage tank 20, and multiple hoses 22 are fixedly connected to the output end of the delivery pump 21. One end of each delivery hose 22 is fixedly connected to a corresponding spray nozzle 17. A control valve is fixedly installed inside the delivery hose 22.

[0028] When spraying the outer casing of a new energy vehicle battery, the third motor 11 and the corresponding fourth motor 18 rotate, which can drive the corresponding spray nozzle 17 to move horizontally and vertically, so that the outer casing of the new energy vehicle battery can be sprayed comprehensively. Furthermore, the distance between the spray nozzle 17 and the outer casing of the new energy vehicle battery can be adjusted by the electric push rod 16, which can improve the spraying effect.

[0029] It should be noted that, as Figure 1 and Figure 2 As shown, an operating platform 5 is fixedly installed on one side of the upper surface of the base plate 1. The operating platform 5 can be used to control the electrical appliances (such as motors) in various mechanisms. Control via the operating platform 5 is common knowledge known to those skilled in the art, and therefore is not described in detail.

[0030] Working principle: During use, the cylinder 3 operates, which drives the protective cover 2 to rise and fall, facilitating the handling and placement of the new energy vehicle battery casing. When fixing the new energy vehicle battery casing, it is placed on top of the two support rods 8. Then, the second motor 10 rotates, driving the bidirectional lead screw to rotate. Through the thread, the support rods 8 on both sides can move relative to each other. With the help of the top block 9, it can be fixed from the inside of the new energy vehicle battery casing. During the spraying process, the first motor 6 rotates, which drives the new energy vehicle battery casing to rotate, thus facilitating the spraying of the other two sides of the new energy vehicle battery casing and improving practicality. When spraying the new energy vehicle battery casing, the third motor 11 and the corresponding fourth motor 18 rotate, which can drive the corresponding spray nozzle 17 to move horizontally and vertically, allowing for comprehensive spraying of the new energy vehicle battery casing. Furthermore, the distance between the spray nozzle 17 and the new energy vehicle battery casing can be adjusted by the electric push rod 16, which can improve the spraying effect.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
