Description

Technical Field

[0001] The present invention belongs to the technical field of battery shell cleaning, and in particular relates to a device and method for cleaning an aluminum shell of a blade battery. Background Art

[0002] Blade batteries, named for their long, thin appearance, utilize a laminated structure and ceramic coating technology. This innovative design eliminates the need for a "module" during assembly, significantly improving space utilization and accommodating more cells within the same space. During production, the battery casing surface must be cleaned to ensure good insulation properties.

[0003] Currently, when cleaning the blade battery housing, impurities will remain in the middle section of the inner wall of the battery housing, thereby reducing the cleaning effect. In response to the above technical problems, the applicant has retrieved some existing technologies to achieve the cleaning of impurities remaining in the middle section of the inner wall of the battery housing. For example, patent publication number CN221133472U is a blade battery housing inner wall cleaning machine. Its main technical means is that when cleaning, the blade battery housing is in a horizontal posture. At this time, the jet cleaning head sprays water towards the end portion of the blade battery housing. The water flows into the blade battery housing and uses the high-pressure water flow to flush away impurities on the inner wall of the blade battery housing, thereby improving the cleaning effect of the inner wall of the blade battery housing. After analysis by the applicant, the disadvantage of this technical solution is that the blade battery housing is installed in the cleaning basket in the above solution, so that the blade battery housing is bound to be in contact with the surface of the cleaning basket. This results in a cleaning dead angle in the contact part between the blade battery housing and the surface of the cleaning basket, thereby reducing the cleaning effect of the blade battery housing.

[0017] A cleaning method for a blade battery aluminum shell cleaning device, the method being applied to the blade battery aluminum shell cleaning device as described above, the method comprising the following steps:

[0018] Step S1: First, pull the slide out of the hanging basket, then install the aluminum shell body between the upper and lower sets of clamping blocks 1, 2 and 3. After all the aluminum shell bodies are installed in this way, push the slide into the hanging basket, and finally place the hanging basket into the cleaning tank filled with cleaning fluid through external lifting equipment;

[0019] Step S2: starting the ultrasonic generator and the liquid pump. The cleaning liquid is affected by the ultrasonic generator to generate high-frequency vibration to clean the surface of the aluminum shell body. The liquid pump extracts the cleaning liquid, so that the cleaning liquid in the cleaning tank presents multiple groups of vortices flowing downward.

[0020] Step S3: The vortex flowing downward drives the impeller to rotate, and the impeller rotates the reciprocating screw through the transmission member. The reciprocating screw causes the slider to drive the clamping block 1 or the clamping block 2 to move back and forth along the direction of the reciprocating screw to prevent the aluminum shell from having a dead corner when being cleaned. The clamping block 1 or the clamping block 2 reciprocates to polish the end of the aluminum shell;

[0021] Step S4: The cleaning liquid presents a vortex of downward flow, so that the cleaning liquid in the vortex state flows downward from the top of the aluminum shell body to clean the inner wall of the aluminum shell body. After cleaning, the hanging basket is pulled out of the cleaning pool through external lifting equipment.

[0022] The beneficial effects of the present invention are:

[0023] 1. In the present invention, the cleaning liquid in the cleaning pool is discharged through the drain cylinder. After entering the drain cylinder, the cleaning liquid is guided by the spiral guide plate, so that the cleaning liquid slowly presents a vortex state, and the vortex state slowly extends to the liquid surface of the cleaning liquid. The cleaning liquid in the vortex state drives the driving assembly to make the clamping member move back and forth. The reciprocating clamping member puts the aluminum shell body in a dynamic clamping state, which can effectively avoid the existence of cleaning dead corners of the aluminum shell body when being cleaned, so that the aluminum shell body is fully cleaned, thereby improving the cleaning effect of the aluminum shell body;

[0024] 2. In the present invention, the vortex cleaning liquid flows from top to bottom, and part of the cleaning liquid passes through the interior of the aluminum shell body, so that the cleaning liquid can flush the inner wall of the aluminum shell body, thereby improving the cleaning effect of the inner wall of the aluminum shell body and effectively avoiding impurities remaining in the middle section of the inner wall of the aluminum shell body, thereby further improving the cleaning effect of the aluminum shell body;

[0025] 3. In the present invention, the cleaning liquid in the vortex state flows from top to bottom, so that the cleaned oil and impurities will move downward with the vortex and be discharged through the drain tube, avoiding the presence of cleaned oil and impurities in the cleaning liquid in the cleaning pool. This can ensure the cleaning effect of the cleaning liquid on the one hand, and on the other hand, avoid the cleaned oil and impurities from causing secondary pollution to the aluminum shell body, thereby further improving the cleaning effect of the aluminum shell body;

[0026] 4. In the present invention, the first, second and third clamping blocks can grind the ends of the aluminum shell body through the grinding sheet when moving, and grind the burrs on the ends of the aluminum shell body smooth, thereby further improving the cleaning effect of the aluminum shell body. At the same time, this can also save the process of deburring the ends of the aluminum shell body, thereby improving the processing efficiency of the aluminum shell body;

[0027] 5. In the present invention, after the cleaning liquid enters the drain tube, the cleaning liquid is in a vortex state, so the oil and impurities cleaned are attached to the inner wall of the drain tube due to the action of centrifugal force, and due to the gravity of the oil and impurities, the oil and impurities slowly sink to the tapered portion. With the obstruction of the filter screen, since the density of the cleaning liquid is less than the density of the oil and impurities, the cleaning liquid will enter the drain pipe and return to the cleaning tank again through the suction pipe and the liquid inlet pipe, so that the cleaning liquid circulates. At the same time, the oil and impurities in the cleaning liquid can be filtered out, which reduces the loss of the cleaning liquid on the one hand and ensures the cleaning effect of the cleaning liquid on the other hand.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] like Figures 1-9 As shown, a blade battery aluminum shell cleaning device includes a cleaning tank 2, an ultrasonic generator 21 and a hanging basket 3, and the device also includes:

[0041] The slide plate 4 is provided with several sets of slide rails 31 at the top and bottom of the inner side of the hanging basket 3. The slide plate 4 includes two sets of U-shaped frames 41. One side of the two sets of U-shaped frames 41 is fixed by a connecting plate 42. The two sets of U-shaped frames 41 are slidably mounted on the two sets of slide rails 31. The slide plate 4 is installed in a pull-out manner with the hanging basket 3.

[0042] Clamping parts 5: Several groups of clamping parts 5 are movably installed on the top and bottom of the inner side of the U-shaped frame 41, and the aluminum shell body 1 is clamped between two groups of clamping parts 5 corresponding to the upper and lower positions;

[0043] Drive assembly 7, a plurality of drive assemblies 7 are installed on the slide 4, and the drive assembly 7 drives the clamping member 5 to move back and forth;

[0044] Drain tubes 8 , a plurality of drain tubes 8 are installed at the bottom of the cleaning tank 2 , and spiral guide plates 82 are provided in the drain tubes 8 , and the spiral guide plates 82 are close to the top ends of the drain tubes 8 .

[0045] In one case of this embodiment, the drain cylinders 8 are located directly below the aluminum shell body 1 , and the number of the drain cylinders 8 is the same as the number of the aluminum shell bodies 1 that can be placed in the hanging basket 3 .

[0046] In actual application of this embodiment, the cleaning liquid in the cleaning pool 2 is discharged through the drain cylinder 8. After entering the drain cylinder 8, the cleaning liquid is guided by the spiral guide plate 82, so that the cleaning liquid slowly presents a vortex state, and the vortex state slowly extends to the liquid surface of the cleaning liquid. The cleaning liquid in the vortex state drives the driving assembly 7 to make the clamping member 5 move back and forth. The reciprocating clamping member 5 puts the aluminum shell body 1 in a dynamic clamping state, so that the aluminum shell body 1 can be effectively avoided from having a cleaning dead angle when being cleaned, so that the aluminum shell body 1 is fully cleaned, thereby improving the cleaning effect of the aluminum shell body 1;

[0047] Since the cleaning liquid is in a vortex state and the vortex coincides with the aluminum shell body 1, the vortex will collide with the aluminum shell body 1, causing the aluminum shell body 1 to be in a shaking state when being cleaned, thereby making it easier to clean the oil or impurities attached to the aluminum shell body 1, further improving the cleaning effect of the aluminum shell body 1;

[0048] The vortex cleaning liquid flows from top to bottom, and part of the cleaning liquid passes through the interior of the aluminum shell body 1, so that the cleaning liquid can flush the inner wall of the aluminum shell body 1, thereby improving the cleaning effect of the inner wall of the aluminum shell body 1 and effectively avoiding impurities remaining in the middle section of the inner wall of the aluminum shell body 1, thereby further improving the cleaning effect of the aluminum shell body 1;

[0049] The cleaning liquid in the vortex state flows from top to bottom, so that the cleaned oil and impurities will move downward with the vortex and be discharged through the drain tube 8, avoiding the presence of cleaned oil and impurities in the cleaning liquid in the cleaning tank 2. On the one hand, this can ensure the cleaning effect of the cleaning liquid, and on the other hand, it can avoid the cleaned oil and impurities from causing secondary pollution to the aluminum shell body 1, thereby further improving the cleaning effect of the aluminum shell body 1.

[0050] Furthermore, the clamping member 5 includes a clamping block 51 and a clamping block 52, both of which are U-shaped. The lower group of clamping blocks 51 and 52 are against the bottom of the long side of the aluminum shell body 1, and the upper group of clamping blocks 51 and 52 are against the top of the long side of the aluminum shell body 1.

[0051] In actual application, the aluminum shell body 1 is clamped by the upper and lower sets of clamping blocks 1 51 and clamping blocks 2 52, thereby improving the stability of the aluminum shell body 1 and effectively preventing the aluminum shell body 1 from escaping from the clamping blocks 1 51 and clamping blocks 2 52 during the cleaning process, thereby preventing the aluminum shell body 1 from colliding with the hanging basket 3 and being deformed and damaged.

[0052] Furthermore, a plurality of mounting grooves 411 are provided on the inner side of the C-shaped frame 41, and two reciprocating screw rods 6 are symmetrically mounted in the mounting grooves 411 for rotation. Elastic members 56 are provided at the bottom of the clamping block 1 51 and the clamping block 2 52, and a slider 55 is provided at the bottom of the elastic member 56. The sliders 55 on the clamping block 1 51 and the clamping block 2 52 on the same horizontal plane are respectively mounted on the periphery of the two reciprocating screw rods 6. The driving assembly 7 includes an impeller 71 and a transmission member 72. The impeller 71 is rotatably mounted between the two groups of C-shaped frames 41, and one end of the transmission member 72 is transmission-connected to the impeller 71. There are two groups of transmission members 72, and the other ends of the two groups of transmission members 72 are respectively transmission-connected to the two reciprocating screw rods 6 at the same position on the two groups of C-shaped frames 41. The two reciprocating screw rods 6 at the same position on the two groups of C-shaped frames 41 correspond to one group of driving assembly 7.

[0053] In one case of this embodiment, the transmission member 72 can be composed of a rotating rod and bevel gears at both ends of the rotating rod. A bevel gear is also provided on the rotating shaft of the impeller 71, and a bevel gear is also provided at one end of the reciprocating screw 6.

[0054] In actual application of this embodiment, after the impeller 71 is driven to rotate by the cleaning liquid in the vortex state, the impeller 71 is driven by the transmission member 72 to rotate the reciprocating screw 6, so that the slider 55 will reciprocate on the reciprocating screw 6, thereby causing the clamping block 1 51 or the clamping block 2 52 to reciprocate, thereby putting the aluminum shell body 1 in a dynamic clamping state, thereby effectively avoiding the existence of cleaning dead corners in the aluminum shell body 1 when being cleaned, so that the aluminum shell body 1 is fully cleaned, and the cleaning effect of the aluminum shell body 1 is improved;

[0055] After the oil stains or impurities on the aluminum shell body 1 are cleaned, the oil stains or impurities can be quickly moved downward by the rotation and guidance of the impeller 71, further preventing the presence of the cleaned oil stains and impurities in the cleaning liquid in the cleaning tank 2.

[0056] Furthermore, a connecting rod 54 is hinged on one side of the clamp block 2 52, and a clamp block 3 53 is hinged on the other end of the connecting rod 54. The clamp block 3 53 connected to the lower clamp block 2 52 rests on the bottom of the short side of the aluminum shell body 1, and the clamp block 3 53 connected to the upper clamp block 2 52 rests on the top of the short side of the aluminum shell body 1.

[0057] The structures of the clamping block 1 51 , the clamping block 2 52 and the clamping block 3 53 are the same. The surfaces of the clamping block 1 51 , the clamping block 2 52 and the clamping block 3 53 contacting the aluminum shell body 1 are all provided with grinding sheets.

[0058] In actual application of this embodiment, when the second clamping block 52 moves back and forth, the second clamping block 52 will drive the connecting rod 54 to move, so that the third clamping block 53 moves along the short side of the aluminum shell body 1, and cooperates with the first clamping block 51 and the second clamping block 52 to move along the long side of the aluminum shell body 1, which can further improve the stability of the aluminum shell body 1; in addition, the first clamping block 51, the second clamping block 52 and the third clamping block 53 can grind the end of the aluminum shell body 1 through the grinding sheet when moving, and grind the burrs on the end of the aluminum shell body 1 smooth, thereby further improving the cleaning effect of the aluminum shell body 1, and at the same time, it can also save the process of deburring the end of the aluminum shell body 1, thereby improving the processing efficiency of the aluminum shell body 1.

[0059] like Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, a conical portion 81 is provided at the bottom of the drain cylinder 8, and a drain pipe 83 is installed in the drain cylinder 8. The bottom end of the drain pipe 83 faces the conical portion 81, and the other end extends out of the drain cylinder 8. A filter screen 831 is installed at one end of the drain pipe 83 close to the conical portion 81.

[0060] Furthermore, a plurality of liquid discharge pipes 83 are connected to the liquid extraction pipe 9 , and a liquid extraction pump 10 is installed at the other end of the liquid extraction pipe 9 . The liquid extraction pump 10 is also connected to a liquid inlet pipe 11 , and the liquid inlet pipe 11 extends into the cleaning tank 2 .

[0061] In actual application of this embodiment, the suction pump 10 extracts the cleaning liquid in the cleaning pool 2 through several drainage tubes 8, which makes it convenient for the cleaning liquid to be in a vortex state; after the cleaning liquid enters the drainage tube 8, since the cleaning liquid is in a vortex state, the oil and impurities cleaned are adhered to the inner wall of the drainage tube 8 due to the action of centrifugal force, and due to the gravity of the oil and impurities, the oil and impurities slowly sink to the tapered portion 81, and cooperate with the obstruction of the filter mesh 831. Since the density of the cleaning liquid is less than the density of the oil and impurities, the cleaning liquid will enter the drainage pipe 83 and return to the cleaning pool 2 again through the suction pipe 9 and the liquid inlet pipe 11, so that the cleaning liquid circulates, and at the same time, the oil and impurities in the cleaning liquid can be filtered out, which on the one hand reduces the loss of the cleaning liquid, and on the other hand ensures the cleaning effect of the cleaning liquid.

[0063] Step S1: First, pull the slide 4 out of the hanging basket 3, and then install the aluminum shell body 1 between the upper and lower sets of clamping blocks 1 51, clamping block 2 52 and clamping block 3 53. After all the aluminum shell bodies 1 are installed in this way, push the slide 4 into the hanging basket 3, and finally place the hanging basket 3 into the cleaning tank 2 filled with cleaning fluid through external lifting equipment;

[0064] Step S2: starting the ultrasonic generator 21 and the liquid extraction pump 10. The cleaning liquid is affected by the ultrasonic generator 21 to generate high-frequency vibration to clean the surface of the aluminum shell body 1. The liquid extraction pump 10 extracts the cleaning liquid, so that the cleaning liquid in the cleaning tank 2 presents multiple groups of vortices flowing downward;

[0065] Step S3: The vortex flowing downward drives the impeller 71 to rotate, and the impeller 71 rotates the reciprocating screw 6 through the transmission member 72. The reciprocating screw 6 causes the slider 55 to drive the clamping block 1 51 or the clamping block 2 52 to reciprocate along the direction of the reciprocating screw 6 to prevent the aluminum shell body 1 from having a cleaning dead corner when being cleaned. The clamping block 1 51 or the clamping block 2 52 reciprocates to polish the end of the aluminum shell body 1;

[0066] Step S4: The cleaning liquid presents a vortex of downward flow, so that the cleaning liquid in the vortex state flows downward from the top of the aluminum shell body 1 to clean the inner wall of the aluminum shell body 1. After cleaning, the hanging basket 3 is pulled out of the cleaning pool 2 by external lifting equipment.

The clamping block 1 (51) or the clamping block 2 (52) moves back and forth to polish the end of the aluminum shell body (1); Step S4: The cleaning liquid presents a vortex of downward flow, so that the cleaning liquid in the vortex state flows downward from the top of the aluminum shell body (1) to clean the inner wall of the aluminum shell body (1). After cleaning, the hanging basket (3) is pulled out of the cleaning tank (2) through the external lifting equipment.
