Description

Technical Field

[0001] This utility model relates to the field of battery casing rust prevention technology, and in particular to a battery casing rust prevention spraying device. Background Technology

[0002] To improve the service life of battery casings, rust-preventive liquid needs to be sprayed onto the surface of the battery casing during the production process to form a uniform and dense rust-preventive coating, thereby preventing corrosive media such as oxygen and moisture from contacting the battery casing.

[0003] Traditional techniques mostly involve manually spraying rust inhibitors, which suffers from low efficiency and poses health risks to operators. Current technology, by using semi-automatic spraying equipment, can effectively improve efficiency, and operators do not need to directly contact the rust inhibitor, reducing health hazards.

[0004] For example, Chinese Patent [Publication No.: CN222306108U] discloses a surface treatment device for aluminum shells of lithium batteries, which includes a workbench, a support on the top of the workbench, a plurality of electric push rods on the top of the support, and a spray hood installed on the output end of the plurality of electric push rods. The surface of the spray hood is provided with a concave tube, and L-shaped tubes are connected to the front and rear sides of the concave tube. A connecting pipe is provided at the top of the concave tube. A plurality of atomizing nozzles are connected to the side walls of the concave tube and the L-shaped tube. The surface of the workbench is provided with a collection structure, which includes a mounting frame. The surface of the workbench is provided with a rectangular groove for mounting the mounting frame.

[0005] However, the above-mentioned device requires operators to manually flip the battery casing during use, which is quite troublesome. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a battery casing anti-rust spraying device to solve the problem that in the prior art, it is more troublesome for operators to manually flip the battery casing.

[0007] This utility model solves the above-mentioned technical problems through the following technical means:

[0008] A battery casing anti-rust spraying device includes a housing, a clamping assembly, a first driving assembly, a second driving assembly, and a peripheral spraying assembly and an end-face spraying assembly fixedly disposed within the housing. One end of the housing has a feed inlet. The clamping assembly clamps the battery casing. The first driving assembly drives the clamping assembly to move along the length of the housing. When the clamping assembly passes the battery casing through the peripheral spraying assembly, the peripheral spraying assembly sprays the periphery of the battery casing. The top of the housing has a discharge outlet. A support plate is disposed within the housing. The second driving assembly drives the support plate to move along the height of the housing. When the clamping assembly places the battery casing on the support plate, and the support plate drives the battery casing through the end-face spraying assembly, the end-face spraying assembly sprays both ends of the battery casing.

[0009] By configuring the above structure, the battery casing is placed on the clamping assembly. The first drive assembly moves the clamping assembly and the battery casing into the housing. As the battery casing passes the peripheral spraying assembly, the peripheral spraying assembly sprays rust-preventive liquid onto the periphery of the battery casing. Once the battery casing is above the support plate, the clamping assembly releases the battery casing, allowing it to fall onto the support plate. The second drive assembly then moves the support plate and the battery casing upwards until the battery casing enters the discharge port. As the battery casing passes the end spraying assembly, the end spraying assembly sprays rust-preventive liquid onto the left and right end faces of the battery casing. This eliminates the need to flip the battery casing, effectively reducing the workload for operators.

[0010] Furthermore, the clamping assembly includes a frame and a clamping head. The frame is slidably disposed inside the box along the length of the box, and the clamping head is fixedly installed at one end of the inner side of the frame. The first driving assembly is connected to the frame in a transmission manner, and the peripheral spraying assembly is located inside the frame.

[0011] By setting up the above structure, it is effectively prevented that the movement of the battery case by the clamping component will affect the normal spraying of the peripheral spraying component.

[0012] Furthermore, the peripheral spraying assembly includes a mounting frame and multiple peripheral spray nozzles. The mounting frame is detachably connected to the inner wall of the housing. The multiple peripheral spray nozzles are evenly fixedly installed on the inner side wall of the mounting frame. The frame includes two end plates and two side plates that are fixedly connected. The front and rear sides of the mounting frame are provided with through slots, and the side plates are slidably disposed in the through slots.

[0013] By setting up the above structure, the drive frame can be slidably connected along the length of the housing, and multiple peripheral nozzles can be removed together by disassembling the mounting frame, which facilitates later maintenance and repair.

[0014] Furthermore, the clamping head includes a mounting post arranged along the length of the frame, a sliding cylinder slidably sleeved on the mounting post along the length of the mounting post, a compression spring arranged between the sliding cylinder and the mounting post, the compression spring being used to give the sliding cylinder a tendency to slide away from the mounting post, the sliding cylinder cooperating with the inner end wall of the frame to clamp the battery case, a limit plate fixedly arranged on the sliding cylinder, when the limit plate abuts against the mounting frame, the mounting frame preventing the limit plate from moving into the box.

[0015] By setting up the above structure, when the battery case moves above the support plate, the sliding cylinder automatically disengages from the battery case, allowing the battery case to fall automatically onto the support plate.

[0016] Furthermore, a slot is provided at the end of the frame away from the clamping head. The slot is used to avoid the second drive component. Clamping blocks are fixedly provided on the side walls on both sides of the slot. The clamping blocks cooperate with the clamping head to clamp the battery case.

[0017] By setting the above structure, interference between the frame and the second drive component is avoided. During the operation of the second drive component, after the second drive component drives the battery case to detach from the clamping block, the first drive component can drive the frame to exit the box.

[0018] Furthermore, the second drive assembly includes a drive cylinder, which is fixedly installed at the bottom of the housing, and the output end of the drive cylinder is fixedly connected to the support plate.

[0019] Furthermore, the first drive assembly includes a drive motor and a transmission screw. The drive motor is fixedly mounted on the housing. A connecting plate is provided at one end of the frame near the drive motor. The transmission screw is rotatably mounted inside the housing. The connecting plate is threadedly connected to the transmission screw. The drive motor and the transmission screw are connected in a transmission connection.

[0020] Furthermore, support bars are provided on both sides of the box body, and the support bars are attached to the lower surface of the frame.

[0021] By setting up the above structure, the support bars support the side plates, making the movement of the drive frame more stable.

[0022] Furthermore, a collection box is provided at the bottom of the box body, and the bottom of the box body is connected to the top of the collection box.

[0023] By setting up the above structure, excess rust inhibitor can be collected in a collection tank for recycling.

[0024] Furthermore, an extension groove is provided at one end of the box body near the feed inlet.

[0025] By setting up the above structure, the battery case can be temporarily stored in the extension slot when it is pushed into the box, and the height between the battery case and the support plate can be easily controlled.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, by setting up a clamping assembly, a first driving assembly, a second driving assembly, a peripheral spraying assembly, an end-face spraying assembly, and a support plate, places the battery case on the clamping assembly. The first driving assembly drives the clamping assembly and the battery case into the housing. When the battery case passes through the peripheral spraying assembly, the peripheral spraying assembly sprays rust-preventive liquid onto the periphery of the battery case. When the battery case is above the support plate, the clamping assembly releases the battery case, allowing it to fall onto the support plate. Then, the second driving assembly drives the support plate and the battery case upwards until the battery case enters the discharge port. When the battery case passes through the end-face spraying assembly, the end-face spraying assembly sprays rust-preventive liquid onto the left and right end faces of the battery case. There is no need to flip the battery case, effectively reducing the workload of the operator.

[0028] 2. This utility model, by setting up a frame, mounting column, sliding cylinder, compression spring and mounting frame, allows the sliding cylinder to automatically disengage from the battery case when it moves above the support plate, so that the battery case automatically falls onto the support plate.

[0029] 3. By setting through slots and clamping blocks, this utility model avoids interference between the frame and the second drive component. During the operation of the second drive component, after the second drive component drives the battery case to detach from the clamping block, the first drive component can drive the frame to exit the box.

Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0047] like Figures 1-6 As shown, a battery casing anti-rust spraying device of this utility model includes a housing 1, a clamping assembly 2, a first driving assembly 3 and a second driving assembly 4, as well as a peripheral spraying assembly 5 and an end-face spraying assembly 6 fixedly installed inside the housing 1. One end of the housing 1 is provided with a feed port 11. The clamping assembly 2 is used to clamp the battery casing. The first driving assembly 3 is used to drive the clamping assembly 2 to move along the length direction of the housing 1. When the clamping assembly 2 places the battery casing on the support plate 7, and the clamping assembly 2 clamps the battery casing through the peripheral spraying assembly 5, the peripheral spraying assembly 5 sprays the peripheral side of the battery casing. The top of the housing 1 is provided with a discharge port 12. The support plate 7 is provided inside the housing 1. The second driving assembly 4 is used to drive the support plate 7 to move along the height direction of the housing 1. When the support plate 7 drives the battery casing through the end-face spraying assembly 6, the end-face spraying assembly 6 sprays both ends of the battery casing.

[0048] In use, the battery case is placed on the clamping assembly 2. The first drive assembly 3 drives the clamping assembly 2 and the battery case into the housing 1. When the battery case passes through the peripheral spraying assembly 5, the peripheral spraying assembly 5 sprays rust-preventive liquid onto the periphery of the battery case. When the battery case is above the support plate 7, the clamping assembly 2 releases the battery case, allowing it to fall onto the support plate 7. Then, the second drive assembly 4 drives the support plate 7 and the battery case to rise until the battery case enters the discharge port 12. When the battery case passes through the end face spraying assembly 6, the end face spraying assembly 6 sprays rust-preventive liquid onto the left and right end faces of the battery case. There is no need to flip the battery case, effectively reducing the workload of the operator.

[0049] In this embodiment, the clamping assembly 2 includes a frame 21 and a clamping head 22. The frame 21 is slidably disposed within the housing 1 along its length. The clamping head 22 is fixedly installed at one end of the inner side of the frame 21. The first drive assembly 3 is connected to the frame 21 in a transmission manner, and the peripheral spraying assembly 5 is located inside the frame 21. In some other embodiments, a motor-controlled drive head can also be provided at the open end of the housing 1. By controlling the operation of two motors, the clamping and movement of the battery case can be achieved. In this embodiment, by setting the frame 21 and the clamping head 22, the normal spraying of the peripheral spraying assembly 5 is effectively avoided during the movement of the battery case by the clamping assembly 2.

[0050] In this embodiment, the peripheral spraying assembly 5 includes a mounting frame 51 and multiple peripheral nozzles 52. The mounting frame 51 is rectangular. It is understood that the peripheral nozzles 52 are connected to a pump body via pipes, as already fully disclosed in the prior art, and therefore will not be described in detail here. The mounting frame 51 is detachably connected to the inner wall of the housing 1. The multiple peripheral nozzles 52 are evenly and fixedly installed on the inner side wall of the mounting frame 51. The frame 21 includes two end plates 211 and two side plates 212 that are fixedly connected. Through slots 511 are provided on both the front and rear sides of the mounting frame 51, and the side plates 212 are slidably disposed in the through slots 511. In some other embodiments, the peripheral nozzles 52 can also be directly fixedly connected to the housing 1. In this embodiment, by setting the mounting frame 51, the drive frame is slidably connected along the length of the housing 1, and the multiple peripheral nozzles 52 can be removed together by disassembling the mounting frame 51, which is convenient for later maintenance and repair.

[0051] In this embodiment, the clamping head 22 includes a mounting post 221 arranged along the length of the frame 21. A sliding cylinder 222 is slidably sleeved on the mounting post 221 along its length. A compression spring 223 is provided between the sliding cylinder 222 and the mounting post 221. The compression spring 223 is used to make the sliding cylinder 222 tend to slide away from the mounting post 221. That is, the compression spring 223 forces the sliding cylinder 222 to cooperate with the inner end wall of the frame 21 to clamp the battery case. A limit plate 224 is fixedly provided on the sliding cylinder 222. When the limit plate 224 abuts against the mounting frame 51, the mounting frame 51 prevents the limit plate 224 from moving into the housing 1. In some other embodiments, the clamping head 22 can also be set as an electric clamping head to achieve automatic release from the clamping of the battery case. In this embodiment, by setting up a sliding cylinder 222 and a compression spring 223, when the battery case moves above the support plate 7, the sliding cylinder 222 automatically disengages from the clamping of the battery case, so that the battery case automatically falls onto the support plate 7.

[0052] It should be noted that the height difference between the battery casing and the support plate 7 should be minimized as much as possible while meeting the spraying requirements. This is to avoid the battery casing falling on the support plate 7 and affecting the anti-rust liquid sprayed on the bottom of the battery casing if the height difference between the battery casing and the support plate 7 is too large.

[0053] In this embodiment, a slot 213 is provided at the end of the frame 21 away from the clamping head 22. The slot 213 is used to avoid the second drive assembly 4. Clamping blocks 214 are fixedly provided on the side walls on both sides of the slot 213. The clamping blocks 214 cooperate with the clamping head 22 to clamp the battery case. In some other embodiments, the through slot 511 may not be provided, but the frame 21 can only exit the housing 1 after the second drive assembly 4 has completed its lifting and lowering actions. In this embodiment, by providing the slot 213 and the clamping blocks 214, interference between the frame 21 and the second drive assembly 4 is avoided. During the operation of the second drive assembly 4, after the second drive assembly 4 drives the battery case to disengage from the clamping blocks 214, the first drive assembly 3 can drive the frame 21 to exit the housing 1.

[0054] In this embodiment, the second drive assembly 4 includes a drive cylinder 41, which is fixedly installed at the bottom of the housing 1, and the output end of the drive cylinder 41 is fixedly connected to the support plate 7.

[0055] In this embodiment, the first drive assembly 3 includes a drive motor 31 and a transmission screw 32. The drive motor 31 is fixedly mounted on the housing 1. A connecting plate 23 is provided at one end of the frame 21 near the drive motor 31. The transmission screw 32 is rotatably mounted inside the housing 1. The connecting plate 23 is threadedly connected to the transmission screw 32. The drive motor 31 is drive-connected to the transmission screw 32. In this embodiment, the transmission screw 32 is located on one side inside the housing 1, and a limiting rod for smooth movement of the connecting plate 23 is provided on the opposite side. In other embodiments, two transmission screws 32 and two connecting plates 23 can be provided. The two connecting plates 23 are respectively located on both sides of the end of the frame 21. The two transmission screws 32 are drive-connected to the two connecting plates 23 respectively. A synchronous belt is provided between the two transmission screws 32. The output shaft of the drive motor 31 is drive-connected to one of the two transmission screws 32.

[0056] In this embodiment, support bars 13 are provided on both sides inside the housing 1. The support bars 13 are attached to the lower surface of the frame 21 and support the side plate 212, making the movement of the drive frame more stable.

[0057] In this embodiment, a collection box 8 is provided at the bottom of the box 1. The bottom of the box 1 is connected to the top of the collection box 8. Excess rust inhibitor can be collected through the collection box 8 for recycling.

[0058] In this embodiment, an extension groove 14 is provided at one end of the housing 1 near the feed port 11. When the battery case is pushed into the housing 1, it can be temporarily stored in the extension groove 14 to provide support for the battery case and facilitate the control of the height between the battery case and the support plate 7.

[0059] The working principle of this utility model is as follows:

[0060] First, move the sliding cylinder 222 away from the housing 1 to further compress the compression spring 223 and place the battery case in the extension slot 14. Then release the sliding cylinder 222, and the compression spring 223 pushes the sliding cylinder 222 to move towards the battery case until the sliding cylinder 222 cooperates with the clamping block 214 to clamp the battery case.

[0061] Subsequently, the drive motor 31 is controlled to work, and the drive motor 31 drives the transmission screw 32 to rotate. The transmission screw 32 drives the frame 21 and the battery case to move into the box 1 through the connecting plate 23.

[0062] As the battery case passes through the peripheral spraying assembly 5, the peripheral spraying assembly 5 is controlled to spray rust-preventive liquid onto the periphery of the battery case. After the battery case is positioned above the support plate 7, the limiting plate 224 abuts against the mounting frame 51. The mounting frame 51 prevents the limiting plate 224 from moving into the housing 1 and further compresses the compression spring 223. The frame 21 continues to move into the housing 1, causing the sliding cylinder 222 to disengage from the clamping of the battery case, thereby allowing the battery case to fall onto the support plate 7.

[0063] Finally, the drive cylinder 41 is controlled to work, and the drive cylinder 41 pushes the support plate 7 to move upward. When the battery case passes through the end face spraying assembly 6, the end face spraying assembly 6 sprays anti-rust liquid on the left and right end faces of the battery case until the battery case enters the discharge port 12. The operator can then take out the battery case from the discharge port 12.

[0064] During the operation of the drive cylinder 41, after the second drive assembly 4 drives the battery case to disengage from the clamping block 214, it controls the drive motor 31 to work. The drive motor 31 drives the transmission screw 32 to rotate, and the transmission screw 32 drives the frame 21 to move out of the box 1 through the connecting plate 23.

[0065] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
