Description

Technical Field

[0001] The utility model belongs to the technical field of spraying equipment, and particularly relates to a spraying device for battery box processing. Background Technique

[0002] The basic function of the battery box is to accommodate and protect the battery pack. Its structure must ensure sufficient strength while retaining the largest accommodation space. Considering space saving, a frame structure is recommended for the design of the battery box, that is, the side frame and bottom frame are welded with profiles, the material thickness is recommended to be > 3mm, and the profiles are externally soldered or double-sided welded with skins. The preferred shape of the battery box is a regular cuboid, which can be appropriately adjusted according to the layout requirements.

[0003] When spraying the battery box during processing, the battery box needs to be fixed first, and then sprayed from all directions. The existing fixing methods generally include clamping, hanging, bottom support or suction cup adsorption. For example, a spraying device for environmentally friendly aluminum profile battery box processing disclosed in Chinese Patent Publication No. CN217473920U includes "a driving motor, a circular suction cup and a first dryer. The output end of the driving motor is connected to a rotating shaft. A shock-absorbing spring is arranged on the outer wall of the rotating shaft. The end of the rotating shaft is connected to a manipulator. The number of the manipulators is set to two. A plurality of circular suction cups are arranged on the surface of the manipulator. The top of the first dryer is connected to a top plate. A second dryer is installed outside the first dryer. The first dryer and the second dryer are arranged below the manipulator". However, these fixing methods keep the supporting parts unchanged during the spraying process, which results in the inability to spray the supported parts during spraying. After spraying, workers are required to make up the spraying for these missed parts, which is not only time-consuming and laborious, but also likely to cause stratification or peeling of the paint on the painted surface due to the difference in spraying time sequence.

[0004] Therefore, we propose a spraying device for battery box processing to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem in the prior art that the supporting parts of the spraying device remain unchanged, resulting in easy omission of the supported parts during spraying. A spraying device for battery box processing is proposed.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A spraying device for battery box processing, including a frame, a paint tank and a nozzle. A hose is connected between the nozzle and the spraying pipe. The frame includes:

[0008] Mounting plate, the mounting plate is fixedly connected to the upper side of the frame, and both ends of the lower side of the mounting plate are fixedly connected with connecting rods, and the connecting rods are arranged vertically;

[0009] Support frame, the support frame is U-shaped and is used to insert into the battery box to provide support for the battery box, and the middle section of the support frame is fixedly connected to the two connecting rods;

[0010] Moving frame, the moving frame is U-shaped, the moving frame is located inside the support frame, and the nozzle is located directly below the moving frame;

[0011] Electric push rod, the electric push rod is fixedly connected to the lower side of the mounting plate, the output end of the electric push rod is fixedly connected with a driving rod, and the lower end of the driving rod is fixedly connected to the moving frame;

[0012] The electric push rod is arranged vertically, the support frame and the moving frame are arranged horizontally, the electric push rod drives the moving frame to move up and down so that the moving frame is higher or lower than the support frame, and an anti-tilting member is also sleeved on the driving rod.

[0013] Preferably, a limiting sleeve is fixedly connected to one side of the frame close to the hose, and the limiting sleeve is sleeved on the hose and is slidably connected to the hose.

[0014] Preferably, the paint can is fixedly connected to the upper side of the mounting plate.

[0015] Preferably, the anti-tilting member includes an anti-tilting rod arranged directly above the moving frame, a movable sleeve is sleeved on the driving rod, and the movable sleeve is slidably connected to the driving rod.

[0016] Preferably, two convex blocks are fixedly connected to the lower side of the anti-tilting rod.

[0017] Preferably, a limiting ring is fixedly connected between the driving rod and the moving frame and the movable sleeve.

[0018] Preferably, a support is fixedly connected to one side of the movable sleeve away from the anti-tilting rod, and the support is fixedly connected to the nozzle.

[0019] Preferably, blocks are fixedly connected to both sides of the movable sleeve, and stop strips are fixedly connected to both sides of the support frame below the two blocks, and the stop strips are L-shaped and are located on the upper side of the support frame.

[0020] In summary, the technical effects and advantages of the present utility model:

[0021] 1. The battery box processing spraying device has an electric push rod driving the movable frame to move up and down so as to be higher or lower than the supporting frame. When the movable frame is higher than the supporting frame, the battery box placed on the supporting frame will be hung by the movable frame and detached from the supporting frame, so that the nozzle can spray the supporting part of the supporting frame. When the movable frame is lower than the supporting frame, the contact part between the movable frame and the battery box can be sprayed, so that the battery box can be sprayed in all directions, which solves the problem that the existing spraying device easily misses the supporting part and cannot spray.

[0022] 2. The anti-roll bar arranged above the movable frame can slide up and down with the movable sleeve to limit the upper side of the outer side of the battery box. When the battery box tilts, it will conflict with the anti-roll bar, causing the anti-roll bar to deviate from the horizontal, and then the movable sleeve will deviate from the axis of the driving rod and conflict with the driving rod to increase friction, making it difficult for the movable sleeve to move up along the driving rod, so that the anti-roll bar can prevent the battery box from continuing to tilt and slipping off the movable frame, thereby ensuring the stability of the battery box during the spraying process.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] In an embodiment of the present utility model, a spraying device for battery box processing is provided, which solves the problem that the spraying device in the prior art is prone to missing the support parts and unable to spray. The electric push rod 9 drives the movable frame 8 to move up and down so as to be higher or lower than the support frame 7, and then alternately replaces the parts supporting the battery box.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0032] Refer to Figure 1 、 Figure 2 A spraying device for battery box processing includes a frame 1, a paint tank 2 and a nozzle 3. The nozzle 3 is located below the paint tank 2. The paint tank 2 is arranged on the top of the frame 1. A leather tube 4 is connected between the nozzle 3 and the spraying pipe, and the nozzle 3 can move upward. A limit sleeve 12 is fixedly connected to one side of the frame 1 close to the leather tube 4. The limit sleeve 12 is sleeved on the leather tube 4 and is slidably connected to the leather tube 4. The leather tube 4 is limited by the limit sleeve 12 to reduce the swing of the leather tube 4 during use.

[0033] Refer to Figure 1 、 Figure 3 、 Figure 4 The frame 1 includes:

[0034] A mounting plate 5, the mounting plate 5 is horizontally arranged, and the mounting plate 5 is fixedly connected to the upper side of the frame 1. Both ends of the lower side of the mounting plate 5 are fixedly connected with connecting rods 6, and the connecting rods 6 are vertically arranged.

[0035] A support frame 7, the support frame 7 is U-shaped, and is used to be inserted into the battery box and abut against the inner top surface of the battery box, so as to provide support for the battery box, so that the battery box can be hung on the support frame 7 for spraying operation. The middle section of the support frame 7 is fixedly connected with two connecting rods 6, and the connecting rods 6 fixedly connect the support frame 7 under the mounting plate 5.

[0036] A movable frame 8, the movable frame 8 is U-shaped, and the movable frame 8 can also support the battery box. The movable frame 8 is located inside the support 17, and the nozzle 3 is located directly below the movable frame 8. When the battery box is hung on the support frame 7 or the movable frame 8, the nozzle 3 can spray the inside of the battery box.

[0037] An electric push rod 9, the electric push rod 9 is fixedly connected to the lower side of the mounting plate 5, and the output end of the electric push rod 9 is fixedly connected with a driving rod 10. The electric push rod 9 drives the driving rod 10 to reciprocate. The lower end of the driving rod 10 is fixedly connected with the movable frame 8, and the movable frame 8 and the nozzle 3 are driven by the driving rod 10.

[0038] Refer to Figure 1 、 Figure 3 、 Figure 4, the electric push rod 9 is arranged vertically, so that the driving rod 10 moves up and down in the vertical direction. The support frame 7 and the movable frame 8 are arranged horizontally, and both the support frame 7 and the movable frame 8 can support the internal top surface of the battery box, and the horizontal arrangement is more suitable for the top of the rectangular battery box. The electric push rod 9 drives the movable frame 8 to move up and down so that the movable frame 8 is higher or lower than the support frame 7. When the movable frame 8 is lower than the support frame 7, the battery box is supported by the support frame 7, and when the movable frame 8 moves up to be higher than the support frame 7, the movable frame 8 provides support for the battery box and moves up with the battery box. The driving rod 10 is also provided with an anti-tilt member 11 to prevent the battery box from tilting and slipping off the movable frame 8 during the movement, causing the battery box to fall and be damaged.

[0039] Reference Figure 3 , Figure 4 , Figure 5 The anti-roll member 11 includes an anti-roll bar 13 arranged just above the movable frame 8, and the anti-roll bar 13 is arranged horizontally. A movable sleeve 14 is sleeved on the driving rod 10, and the movable sleeve 14 is slidably connected to the driving rod 10, and the driving rod 10 can move parallel to the movable frame 8 with the movable sleeve 14. When the anti-roll bar 13 moves with the movable sleeve 14 to fit with the top of the battery box, the top of the battery box can be limited. When the battery box tilts, the top of the battery box will tilt against the anti-roll bar 13 and drive the anti-roll bar 13 to tilt, and the anti-roll bar 13 will drive the movable sleeve 14 to tilt and deviate from the axis of the driving rod 10. The inner side of the movable sleeve 14 hits the outer periphery of the driving rod 10 to increase the friction between the movable sleeve 14 and the driving rod 10, thereby making it difficult for the anti-roll bar 13 to move along the direction of the driving rod 10 and will not continue to tilt, thereby achieving the effect of blocking the top of the battery box and preventing the battery box from continuing to tilt and falling off the movable frame 8.

[0040] Two protrusions 15 are fixedly connected to the lower side of the anti-roll bar 13. The protrusions 15 change the contact between the anti-roll bar 13 and the top of the battery box from line contact to point contact, reducing the contact area between the anti-roll bar 13 and the top of the battery box, thereby reducing the scratch area when the anti-roll bar 13 is in action. The driving rod 10 is located between the movable frame 8 and the movable sleeve 14 and is fixedly connected to a limiting ring 16. The distance between the limiting ring 16 and the movable frame 8 is greater than the distance between the movable sleeve 14 and the movable frame 8 when the protrusion 15 contacts the top of the battery box, so that when the movable frame 8 supports the battery box, the limiting ring 16 can limit the movable sleeve 14, so that the anti-roll bar 13 is higher than the top of the battery box by a certain distance, and there is an interval between the protrusion 15 and the battery box instead of fitting, thereby preventing the protrusion 15 from contacting the top of the battery box and affecting the spraying effect of the top of the battery box.

[0041] Reference Figure 1 , Figure 3 , Figure 4, on both sides of the movable sleeve 14, there are fixed connection stoppers 18. Below the two stoppers 18, the support frame 7 is fixedly connected with a stop bar 19. The stop bar 19 is L-shaped and is located above the support frame 7. The stop bar 19 consists of a vertical section and a horizontal section. The vertical section is fixedly connected with the support frame 7, and the stop bar 19 is located above the support frame 7. The distance between the horizontal section of the stop bar 19 and the support frame 7 is greater than the distance between the limiting ring 16 and the movable frame 8. When the battery box is hung on the support frame 7 and the driving rod 10 drives the movable frame 8 to move down to a certain position, the stop bar 19 will block the downward movement of the stopper 18, thereby preventing the anti-tilting rod 13 from moving down and contacting the top of the battery box, and avoiding scratching off the coating on the surface of the battery box by the anti-tilting rod 13.

[0042] Refer to Figure 1 , Figure 3 , Figure 5 , on the side of the movable sleeve 14 away from the anti-tilting rod 13, there is a fixed connection with a bracket 17. The bracket 17 is fixedly connected with the nozzle 3. By connecting the nozzle 3 and the driving rod 10 through the bracket 17, when the driving rod 10 drives the movable sleeve 14 to move up, it can drive the nozzle 3 to move up. At the same time, the bracket 17 and the anti-tilting rod 13 are arranged on opposite sides, which is beneficial to maintaining the balance on both sides of the movable sleeve 14.

[0043] Working principle: When in use, the movable frame 8 is driven by the electric push rod 9 to be lower than the support frame 7, and then the support frame 7 is inserted into the battery box and supports the top of the battery box, so that the whole battery box is hung on the support frame 7. The outer periphery of the battery box is sprayed, and at the same time, the nozzle 3 sprays the inside of the battery box. Then, the movable frame 8 driven by the electric push rod 9 moves up, so that the movable frame 8 replaces the support frame 7 to provide support and drives the battery box to move up. At this time, the part of the support frame 7 that provides support for the battery box is exposed and is sprayed by the nozzle 3, so that all positions inside the battery box can be sprayed with paint, without omission and without the need for secondary supplementary spraying.

[0044] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
