Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, in particular to a battery core surface cleaning mechanism and device. Background Art

[0002] Lithium-ion batteries have many advantages over traditional secondary batteries such as lead-acid batteries, nickel-cadmium batteries, and nickel-metal hydride batteries. They have been widely used and studied in recent years. Lithium-ion batteries are composed of battery cells. In the production and manufacturing process of lithium-ion batteries, the battery cells need to be assembled into battery modules. Therefore, the battery cells are the key part of the entire battery. When there is dust and foreign matter remaining on the surface of the battery cells, the dust and foreign matter will remain in the battery cells after entering the shell, which may easily lead to abnormal Hi-pot detection and scrapping of the battery cells in the subsequent process. At the same time, dust after liquid injection will affect the charging and discharging efficiency of the battery cells and reduce the service life of the battery cells. Therefore, the cleanliness of the battery cells needs to be ensured before assembly to avoid the presence of debris in the battery cells, which will affect the service life of the battery.

[0003] Before the battery cells are assembled into battery modules, they need to be cleaned to remove dirt on their surfaces. When cleaning the battery cells, some use manual processing methods, that is, manually use an air gun to clean the front and back of the battery cells, but this cleaning method requires a lot of manpower, a long cleaning time, and low efficiency. Some use automatic control methods, that is, use a cleaning device to automatically clean the battery cells, but the existing cleaning device places the battery cells on a tray and uses air blowing to clean the dust and foreign matter on the surface of the battery cells, but the tray blocks the bottom surface of the battery cells, and the unreasonable setting of the air blowing method results in low air speed in some dead corners and poor dust removal effect. Therefore, how to effectively clean the dust and foreign matter on the surface of the battery cells is a problem that needs to be solved. Utility Model Content

The positioning grooves on all the support platforms form a battery cell placement groove for positioning the battery cell, which locates and limits the position of the battery cell during the cleaning operation. The above-mentioned battery cell placement groove uses multiple support points to hold up the battery cell so that most of the bottom surface of the battery cell will not be blocked. Such an air avoidance design can ensure that the bottom surface of the battery cell can be cleaned; the protective cover can The protective cover moves up and down, and then closes with the support plate to form a closed cavity. The closed cavity can cover the battery cell. The top surface of the protective cover is provided with suction holes for connecting the suction pipe. The suction holes can connect the suction pipe and the closed cavity. The blowing pipes of the blowing assembly are distributed on the upper side of the top surface of the battery cell and the lower side of the bottom surface. The blowing holes are provided on the blowing pipe. Air is blown into the closed cavity through the blowing holes on the blowing pipe, so that the dust and foreign matter attached to the surface of the battery cell are blown away by the gas, and the suction holes on the protective cover extract the gas and dust and foreign matter in the closed cavity.

[0011] As a preferred solution of the utility model, the top surface of the support plate is provided with four support platforms, and the four support platforms form a rectangle matching the shape of the battery cell, and each support platform is located at the corner of the rectangle.

However, the more the number of support platforms, the more effectively the battery cell can be carried, and at the same time, the bottom surface of the battery cell will be blocked. Therefore, support platforms are set at the four corners of the battery cell for support, which can not only effectively carry the battery cell, but also reduce the blocking of the bottom surface of the battery cell, which is conducive to ensuring the cleaning effect of the battery cell.

[0012] As a preferred solution of the utility model, a blank area is provided at the edge of the positioning groove to reduce the obstruction of the surface of the battery cell and facilitate the cleaning of dust and foreign matter.

After experiments by the inventor, it was determined that three blow pipes are provided on the upper side of the top surface of the battery cell, and one blow pipe is provided on the lower side of the bottom surface of the battery cell. This arrangement can provide better blowing kinetic energy and pressure distribution during blowing, and achieve better cleaning effect, effectively solving the problem of unreasonable blowing mode setting in existing cleaning devices, resulting in low blowing speed and poor dust removal effect in some dead corners.

[0040] Example 1

[0041] A battery cell cleaning mechanism, the cleaning mechanism comprising a support plate 1, a blowing assembly and a protective cover 2; the top surface of the support plate 1 is provided with at least two for placing battery cells 4, and the top surface of the support platform 11 is provided with a positioning groove 12 for limiting the position of the battery cell 4; the protective cover 2 can move downward to approach the support plate 1, and close with the support plate 1 to form a closed cavity, so that the support platform 11 and the blowing assembly are located in the formed closed cavity; the top surface of the protective cover 2 is provided with an air intake hole 21 for connecting an air intake pipe 22; the blowing assembly comprises a blowing pipe 3, there are at least two blowing pipes 3, the blowing pipes 3 are distributed on the upper side of the top surface of the battery cell and the lower side of the bottom surface of the battery cell, and the blowing pipe 3 is provided with a blowing hole 31 for blowing air into the closed cavity, such as Figure 1-4 As shown, the cleaning mechanism is described in detail below.

[0042] At least two support platforms 11 are provided for placing the battery cells 4. The positioning grooves 12 on all the support platforms 11 form battery cell 4 placement grooves for positioning the battery cells 4, and positioning and limiting the position of the battery cells 4 during the cleaning operation. The battery cell 4 placement grooves use multiple support points to hold up the battery cells 4, so that most of the bottom surface of the battery cells 4 will not be blocked. Figure 2 It can be seen that the height of the positioning groove 12 is higher than the support plate 1. When the battery cell 4 is placed on the positioning groove 12, a gap is left between the bottom surface of the battery cell 4 and the support plate 1, which can be used to set the blowing component to ensure that the bottom surface of the battery cell 4 can be cleaned. Specifically, in this embodiment, four support platforms 11 are set on the top surface of the support plate 1. The support platforms 11 are square, and the top edge of the support platform 11 adopts a chamfered design; the four support platforms 11 form a rectangle that matches the shape of the battery cell 4, and each support platform 11 is located at the corner of the rectangle. The support platforms 11 are set at the four corners of the battery cell 4 for support, which can not only effectively carry the battery cell 4, but also reduce the obstruction of the bottom surface of the battery cell 4, which is conducive to ensuring the cleaning effect of the battery cell.

[0043] In some embodiments, a support platform 11 is provided on each short side of the battery to form a triangular support, which can stably support the battery cell 4. Furthermore, a blank area is provided at the edge of the positioning groove 12 to reduce the obstruction of the battery cell surface and facilitate the cleaning of dust and foreign matter.

[0044] Furthermore, a chip removal groove 13 is provided at the bottom of the positioning groove 12. The chip removal groove 13 can not only reduce the obstruction of the bottom surface of the battery cell, but also the dust and foreign matter particles on the surface of the battery cell 4 can be discharged or collected through the chip removal groove 13, so as to maintain the cleanliness of the positioning groove 12 and ensure the cleaning effect of the overall cleaning mechanism. Preferably, there is at least one chip removal groove 13, and the chip removal groove 13 extends to the edge of the positioning groove 12 along the long side direction of the battery cell 4, which is conducive to the discharge of dust and foreign matter particles from both ends of the chip removal groove 13. Preferably, the cross-sectional shape of the chip removal groove 13 is rectangular. The cross-sectional shape of the chip removal groove 13 is set to a rectangular shape, so that the chip removal groove 13 has a larger cross-sectional area, which does not affect the discharge of particles such as dust and smoke.

[0045] Blowing pipes 3 are distributed on the upper side of the top surface of the battery cell 4 and the lower side of the bottom surface of the battery cell 4. The blowing pipes 3 are at a certain distance from the top surface of the battery cell 4 or the bottom surface of the battery cell 4. Figure 3 As shown, the blowing pipe 3 is a round pipe, and the pipe wall of the blowing pipe 3 is provided with blowing holes 31 of uniform size. The diameter of the blowing pipe 3 is 14-20 mm, and the diameter of the blowing hole 31 is 2-5 mm. Specifically, the diameter of the blowing pipe 3 used in this embodiment is 15 mm, and the diameter of the hole is 3 mm. There are four blowing pipes 3, of which three blowing pipes 3 are located on the upper side of the top surface of the battery cell, and one blowing pipe 3 is located on the lower side of the bottom surface of the battery cell. The setting position of the air intake hole 21 will weaken the blowing effect of the blowing pipe 3 on the upper side of the battery cell, and the blowing pipe 3 cannot be installed on the side and bottom of the battery cell due to space limitations. After the inventor's experiment, it was determined that three blowing pipes 3 were set on the upper side of the top surface of the battery cell, and one blowing pipe 3 was set on the lower side of the bottom surface of the battery cell. Through such an arrangement, better blowing kinetic energy and pressure distribution can be achieved during blowing, and the cleaning effect is better.

[0046] The blowing assembly also includes a rotating motor and a support frame. The support frame is arranged on the support plate 1. A through hole is arranged on the support frame. The blowing pipe 3 passes through the through hole and is fixedly connected to the output end of the rotating motor. Through the above structure, by controlling the forward and reverse rotation, the blowing pipe 3 can be turned 360°. By controlling the blowing direction of the blowing pipe 3, the gas blown out of the blowing pipe 3 can be distributed to the entire closed cavity, so that the gas can effectively blow the battery cell 4 to ensure the cleaning effect.

[0047] In some embodiments, a sealing strip is provided on the edge where the protective cover 2 contacts the support plate 1. The protective cover 2 can form a closed cavity with the support plate 1, and the sealing strip can ensure the sealing effect and improve the cleaning effect.

[0048] like Figure 4 As shown, for the above-mentioned battery cell cleaning mechanism, the present embodiment adopts a high-pressure blowing method to clean the battery cell 4, the blowing pipe 3 is connected to the high-pressure air pipe, and the air intake hole 21 is connected to the air intake pipe 22. When the battery cell 4 is not placed on the support platform 11, the protective cover 2 is away from the support platform 11. When the battery cell 4 is placed on the support platform 11, the protective cover 2 moves downward to reach a closed cavity that can be closed with the support plate 1, and the high-pressure air pipe passes high-pressure gas, which can come out from the blowing hole 31 on the blowing pipe 33 to blow the battery cell 4 placed on the support platform 11. The dust and foreign matter attached to the surface of the battery cell 4 are blown away by the high-pressure gas, thereby achieving the cleaning of the battery cell 4. In order to ensure the cleanliness of the closed cavity, the high-pressure gas and the dust and foreign matter are discharged from the air intake hole 21 in time to avoid contaminating the closed cavity.

[0049] Example 2

The support plate 1 is made of a plate-like material with a certain thickness. For example, the support plate 1 can be made of a metal or non-metal material. In this embodiment, the support plate 1 is a rectangular plate with a certain thickness. A first motor 6 is connected to the top surface of the protective cover 2 to control the upward and downward movement of the protective cover 2. When the battery cell 4 is placed on the support platform 11, the protective cover 2 can close with the support plate 1 to form a closed cavity when moving downward, so that the battery cell 4 is located in the closed cavity.

[0052] In some embodiments, the cleaning device further includes a gripper disposed on the support plate 1, which can be driven to pick up the battery cell 4 and move it to the support platform 11 for cleaning, and can also be driven to pick up and place the battery cell 4 after the cleaning operation. Specifically, the gripper can be driven by a cylinder to contract to pick up the battery cell 4 or to open to release the battery cell 4. Specifically, when the battery cell 4 is not placed on the support platform 11, the protective cover 2 is away from the support platform 11, and the battery cell 4 is transported to the vicinity of the support plate 1 manually or automatically, the gripper is driven to grip the battery cell 4 and drive the battery cell 4 to move onto the support platform 11, and the protective cover 2 is driven by the first motor 6 to move downward to reach a closed cavity that can be closed with the support plate 1 to form a closed cavity, and the battery cell 4 is placed in the closed cavity, and then the blowing holes 31 on the blowing pipe 3 of the blowing assembly are started to blow air into the closed cavity to blow away dust and foreign matter on the battery cell 4; the air intake port on the protective cover 2 draws out the gas in the enclosed space, and at the same time draws away dust and foreign matter, so as to achieve rapid cleaning of the battery cell 4 and effectively improve work efficiency.

[0053] Therefore, with the help of the battery cell cleaning device in this embodiment, it is possible to automatically clean the dust and foreign matter on the surface of the battery cell, which can not only clean the battery cell in a large range, but also ensure the cleaning effect.
