Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] refer to Figures 1 to 3 The cell dust removal mechanism in this embodiment of the utility model may include a carrier plate 100, a dust removal module 300 and a lifting module 200. The dust removal module 300 is disposed on one side of the carrier plate 100 and the lifting module 200 is disposed on the other side of the carrier plate 100.
[0021] like Figure 2 As shown, the carrier plate 100 has a through hole 110 in the middle. When it is necessary to remove dust from the battery cell 10, the battery cell 10 can be placed and fixed on the lifting module 200 first. Then, the lifting module 200 drives the battery cell 10 to move along the arrangement direction of the dust removal module 300 and the lifting module 200, so that the battery cell 10 can pass through the through hole 110 and move to the dust removal station. That is to say, when the battery cell 10 is in the dust removal station, the battery cell 10 is located on the side of the carrier plate 100 where the dust removal module 300 is provided, so that the dust removal module 300 can remove dust from the battery cell 10.
[0022] Combination Figure 1 and Figure 3 The dust removal module 300 may include a dust removal hood 310, a negative pressure dust removal pipe 330, two sets of ion air knives 320, and two sealing plates 340. The dust removal hood 310 is connected to the carrier plate 100 for covering the battery cell 10. When dust removal is performed on the battery cell 10, the dust removal hood 310 can form a relatively closed area for the battery cell 10 so that gas can be blown onto the surface of the battery cell 10 as much as possible.
[0023] It is worth mentioning that the dust removal mechanism of the battery cell in the embodiment mainly removes dust from the large surface of the battery cell 10. Since the large surface of the battery cell 10 occupies a larger area, the debris is more likely to fall onto the large surface of the battery cell 10. Therefore, the dust removal effect can be better when the dust removal mechanism removes dust from the large surface of the battery cell 10.
[0024] Specifically, the dust removal cover 310 can include a top plate 311 and two side plates 312. The top plate 311 can be arranged parallel to the carrier plate 100 and spaced apart from the carrier plate 100. Two carrier plates 100 are respectively connected between the top plate 311 and the carrier plate 100, so that the top plate 311 and the carrier plate 100 are fixed. The two side plates 312 are oppositely arranged, and at this time, the other two sides of the top plate 311 and the carrier plate 100 can respectively form openings 313. When the battery cell 10 is located at the dust removal station, the top plate 311 is located at the top of the battery cell 10, and the large surface of the battery cell 10 is opposite to the top plate 311.
[0025] Reference Figure 1 Or Figure 4 Two groups of ion wind knives 320 are arranged on opposite sides of the dust removal cover 310. The arrangement direction of the two groups of ion wind knives 320 is parallel to the arrangement direction of the two openings 313. In addition, the ion wind knife 320 and the dust removal cover 310 have a certain spacing, so that the gas can pass through the ion wind knife 320 and then be blown into the dust removal cover 310 through the opening 313. The ion wind knife 320 helps to eliminate static electricity on the surface of the battery cell 10, thereby reducing the adsorption force of foreign matter on the surface of the battery cell 10, so that the gas is more likely to blow the foreign matter off the surface of the battery cell 10 when it is blown onto the surface of the battery cell 10.
[0026] The top plate 311 of the dust removal cover 310 is provided with a dust removal hole (not shown in the figure). The negative pressure dust removal pipeline 330 is located on the side of the top plate 311 away from the carrier plate 100, and the negative pressure dust removal pipeline 330 is in communication with the dust removal hole. The negative pressure dust removal pipeline 330 can be used to form a negative pressure at the dust removal hole, so that the gas in the dust removal cover 310 can flow to the dust removal hole and then flow out through the negative pressure dust removal pipeline 330. In this process, the gas can carry the foreign matter blown off the surface of the battery cell 10 into the negative pressure dust removal pipeline 330, thereby completing the dust removal work on the surface of the battery cell 10.
[0027] For the sake of description and understanding, in the following embodiments, the z direction is set as the arrangement direction of the lifting module 200 and the dust removal module 300, the x direction is set as the arrangement direction of the two groups of ion wind knives 320, and the y direction is set as the arrangement direction of the two side plates 312. The x direction, the y direction and the z direction are perpendicular to each other.
[0028] As Figure 2 And Figure 3As shown, the lifting module 200 can include a bottom plate 210 and a driving assembly (not shown in the figure), and the bottom plate 210 can be provided with a positioning module 211 on the side facing the dust removal cover 310. When the battery cell 10 is placed on the bottom plate 210, the positioning module 211 can position the battery cell 10 to ensure that the battery cell 10 remains fixed during the dust removal process.
[0029] The bottom plate 210 can move relative to the carrier plate 100 in the z direction to change the relative position between the battery cell 10 and the carrier plate 100. When the bottom plate 210 moves to the position where the battery cell 10 is in the dust removal station, as an optional embodiment, the bottom plate 210 can cover the via hole 110. That is, when the battery cell 10 is in the dust removal station, the bottom plate 210 can block the via hole 110, so that the gas below the carrier plate 100 cannot enter or exit the dust removal cover 310 through the via hole 110, thereby reducing the influence of external gas on the dust removal effect.
[0030] When the battery cell 10 completes the dust removal, the bottom plate 210 can move relative to the carrier plate 100 in the z direction to the bottom of the carrier plate 100, which can facilitate the replacement of the battery cell 10, thereby realizing continuous dust removal work.
[0031] Referring again to Figure 1 and Figure 4 , in the x direction, the two sealing plates 340 are located between the two groups of ion wind knives 320, and the two sealing plates 340 are located on the opposite sides of the negative pressure dust removal pipeline 330. The two sealing plates 340 can be provided one by one corresponding to the two groups of ion wind knives 320, and each sealing plate 340 is connected to the side of the top plate 311 of the dust removal cover 310 away from the carrier plate 100. At least a part of the sealing plate 340 can protrude from the end of the opening 313 provided on the dust removal cover 310, so that the sealing plate 340 can fill the gap between the ion wind knife 320 and the dust removal cover 310 in the x direction. Alternatively, the sealing plate 340 can be regarded as a part of the top plate 311, and the top plate 311 can extend in the x direction to contact the ion wind knife 320, so as to eliminate the gap between the ion wind knife 320 and the dust removal cover 310.
[0032] When the gas is blown into the dust removal cover 310, if there is a gap between the ion wind knife 320 and the dust removal cover 310, the gas flowing in the process may blow out of the dust removal cover 310 from the gap between the ion wind knife 320 and the dust removal cover 310. This part of the gas cannot be sucked away by the negative pressure dust removal pipeline 330, thereby affecting the dust removal effect. When the sealing plate 340 is provided, the sealing plate 340 fills the gap between the ion wind knife 320 and the dust removal cover 310, and the gas in the dust removal cover 310 can only be sucked away by the negative pressure dust removal pipeline 330, thereby ensuring the dust removal effect.
[0033] In some embodiments, when the battery cell 10 is placed on the base plate 210, the length direction of the battery cell 10 can be parallel to the x direction. When battery cells 10 of different specifications are placed on the base plate 210 for dust removal, the lengths of the battery cells 10 are different due to the different specifications of the battery cells 10. Based on this, the ion wind knife 320 in the present embodiment can move along the x direction relative to the dust removal cover 310 to adjust the spacing between the ion wind knife 320 and the dust removal cover 310, thereby changing the spacing between the ion wind knife 320 and the battery cell 10.
[0034] It can be understood that a certain spacing is required between the ion wind knife 320 and the battery cell 10, so that when the gas is blown by the ion wind knife 320 to the surface of the battery cell 10, more gas can be blown to the large surface of the battery cell 10. Therefore, by adjusting the positional relationship between the ion wind knife 320 and the dust removal cover 310, good dust removal effect can be maintained when replacing battery cells 10 of different specifications.
[0035] As an optional implementation, referring to Figure 1 and Figure 5 , the ion wind knife 320 can be connected to the carrier plate 100 through the mounting plate 400, the ion wind knife 320 can be relatively fixed with the mounting plate 400, and the mounting plate 400 can move along the x direction relative to the carrier plate 100 to adjust the positional relationship between the ion wind knife 320 and the dust removal cover 310.
[0036] Specifically, the ion wind knife 320 can be connected to the carrier plate 100 through two mounting plates 400, and the two mounting plates 400 are located on opposite sides of the ion wind knife 320 along the y direction. Each mounting plate 400 can include a first connecting plate 410 and a second connecting plate 420, and the first connecting plate 410 is perpendicular to the second connecting plate 420, so that the mounting plate 400 as a whole has an L-shaped structure.
[0037] The first connecting plate 410 is provided with a first waist-shaped hole 411 extending along the x direction. The carrier plate 100 is provided with a first screw hole (not shown in the figure) corresponding to the first connecting plate 410. When the first connecting plate 410 is fixedly connected with the carrier plate 100, the screw can be fixed in the first screw hole after passing through the first waist-shaped hole 411. At this time, the screw and the first waist-shaped hole 411 are fixed, thereby realizing the assembly between the first connecting plate 410 and the carrier plate 100.
[0038] Due to the provision of the first waist-shaped hole 411, when the first connecting plate 410 is fixed with the carrier plate 100, the relative position between the first waist-shaped hole 411 and the first screw hole can be adjusted, so that the screw can be fixed at any position of the first waist-shaped hole 411, thereby adjusting the relative position between the first connecting plate 410 and the carrier plate 100.
[0039] Further, the ion wind knife 320 is connected to the second connecting plate 420, and when the first connecting plate 410 adjusts the relative position with the carrier plate 100, that is, adjusts the relative position between the ion wind knife 320 and the dust cover 310.
[0040] Again referring to Figure 1 and Figure 5 , the ion wind knife 320 is provided with a rotating shaft 321 at each of the two ends in the y direction, and the rotating shaft 321 is fixedly connected with the ion wind knife 320, and the axis of the rotating shaft 321 extends in the y direction. Correspondingly, the side of the second connecting plate 420 away from the first connecting plate 410 can be provided with a mounting groove 421, and the end of the rotating shaft 321 away from the ion wind knife 320 can be mounted in the mounting groove 421, so that the ion wind knife 320 and the second connecting plate 420 are relatively fixed.
[0041] In this embodiment, the ion wind knife 320 can rotate relative to the carrier plate 100 about a first axis, which can be regarded as parallel to the axis of the rotating shaft 321. In this way, the angle between the ion wind knife 320 and the carrier plate 100 is adjusted, so as to realize the adjustment of the blowing angle of the ion wind knife 320 to the battery cell 10.
[0042] Based on this, the rotating shaft 321 can rotate relative to the mounting groove 421, thereby changing the angle between the ion wind knife 320 and the carrier plate 100. As an optional embodiment, the cross-sectional shape of the rotating shaft 321 perpendicular to its axis can be a regular polygon, that is, the rotating shaft 321 is not in the shape of a cylinder, but in the shape of a regular polygonal column. Correspondingly, the shape of the mounting groove 421 can be adapted to the cross-sectional shape of the rotating shaft 321, and when the rotating shaft 321 is mounted in the mounting groove 421, the inner walls of the mounting groove 421 can limit the rotating shaft 321, so as to ensure the relative fixation between the rotating shaft 321 and the mounting groove 421. When it is needed to change the angle between the ion wind knife 320 and the carrier plate 100, the rotating shaft 321 can be first taken out of the mounting groove 421, then rotated to the required angle, and finally fixed in the mounting groove 421 again.
[0043] It is worth noting that when the cross-sectional shape of the rotating shaft 321 is designed as a regular polygon, the angle of the rotating shaft 321 after one rotation can be (360 / n)°, where n is the number of sides of the regular polygon. In this way, after each rotation of the rotating shaft 321, the mounting groove 421 can limit the rotating shaft 321.
[0044] As another optional embodiment, the cross section of the rotating shaft 321 can also be circular, and a limiting structure can be further arranged in the mounting groove 421. When the rotating shaft 321 needs to rotate relative to the mounting groove 421, the limiting structure can be unlocked from the limiting state, and then the rotating shaft 321 can be rotated relative to the mounting groove 421 to a preset angle, and finally the limiting structure can be restored to the limiting state.
[0045] In some embodiments, based on the foregoing embodiments, the ion wind knife 320 can move relative to the dust cover 310 along the x direction, and the sealing plate 340 can also move relative to the dust cover 310 along the x direction, so as to adjust the size of the part of the sealing plate 340 protruding from the top plate 311.
[0046] Specifically, as shown in Figure 1 and Figure 4 , the sealing plate 340 can be provided with a second waist-shaped hole 341 extending along the x direction, and the top plate 311 is provided with a second screw hole (not shown in the figure) corresponding to the second waist-shaped hole 341. When the sealing plate 340 is connected with the top plate 311, the screw can be fixed in the second screw hole after passing through the second waist-shaped hole 341, and the screw and the second waist-shaped hole 341 are also relatively fixed, thereby realizing the relative fixation between the sealing plate 340 and the top plate 311.
[0047] It can be understood that in the embodiment, the relative position between the sealing plate 340 and the top plate 311 can be adjusted by fixing the screw at any position in the second waist-shaped hole 341. For example, when the distance between the ion wind knife 320 and the dust cover 310 increases, the size of the part of the sealing plate 340 protruding from the top plate 311 along the x direction increases, so that the sealing plate 340 can still cover the gap between the ion wind knife 320 and the dust cover 310.
[0048] In some embodiments, different specifications of the battery cell 10 are different in length as described in the foregoing embodiments, and the height of the battery cell 10 is also different. Here, the height of the battery cell 10 can be understood as the size of the battery cell 10 along the z direction when the battery cell 10 is placed on the bottom plate 210.
[0049] Based on this, the height of the ion wind knife 320 in the embodiment can also be adjusted to adapt to the dust removal work of the battery cell 10 of different heights. It should be understood that when the height of the battery cell 10 changes, the distance between the large surface of the battery cell 10 facing the top plate 311 and the carrier plate 100 increases, and if the height of the ion wind knife 320 is not adjusted, the gas blown by the ion wind knife 320 can not reach the large surface of the battery cell 10, thereby affecting the dust removal effect. When the height of the ion wind knife 320 is adaptively adjusted according to the change of the height of the battery cell 10, the dust removal effect can be better guaranteed.
[0050] Reference is made to Figure 1 andFigure 6 The carrier plate 100 can be provided with a wedge block 500 between the carrier plate 100 and the ion wind knife 320. The side of the wedge block 500 facing away from the carrier plate 100 has a slope 510, which gradually decreases in distance between the slope 510 and the carrier plate 100 in the direction in which the ion wind knife 320 points to the dust removal cover 310, that is, the height of the slope 510 is smaller when it is closer to the dust removal cover 310.
[0051] Since the ion wind knife 320 can be fixed to the mounting plate 400 through the rotating shaft 321, when the wedge block 500 is located at the bottom of the ion wind knife 320, a part of the slope 510 of the wedge block 500 can abut against the bottom of the ion wind knife 320, so that the wedge block 500 only supports the ion wind knife 320 in the z direction.
[0052] The wedge block 500 can move in the x direction relative to the carrier plate 100, so as to change the distance between the wedge block 500 and the dust removal cover 310. When the ion wind knife 320 is relatively fixed with the dust removal cover 310 in the x direction, by driving the wedge block 500 to move in the x direction, the relative position between the ion wind knife 320 and the wedge block 500 can be changed. Since the ion wind knife 320 abuts against the slope 510 of the wedge block 500, when the relative position between the ion wind knife 320 and the wedge block 500 changes, the position where the ion wind knife 320 contacts the slope 510 changes. Specifically, when the ion wind knife 320 contacts the side of the slope 510 close to the dust removal cover 310, the height of the ion wind knife 320 is low, and when the ion wind knife 320 contacts the side of the slope 510 away from the dust removal cover 310, the height of the ion wind knife 320 is high.
[0053] It is worth noting that since the ion wind knife 320 is relatively fixed with the mounting plate 400 through the rotating shaft 321 mounted in the mounting groove 421, when the wedge block 500 is arranged at the bottom of the ion wind knife 320, the height of the highest part of the slope 510 should be greater than the distance between the ion wind knife 320 and the carrier plate 100 after the ion wind knife 320 is assembled with the mounting plate 400, so as to ensure that the wedge block 500 can contact the ion wind knife 320. In addition, when the ion wind knife 320 abuts against the height of the slope 510 of the wedge block 500, it is also noted that the rotating shaft 321 does not come out of the mounting groove 421, so as to avoid that the structure of the ion wind knife 320 is unstable, thereby affecting the dust removal effect.
[0054] In some embodiments, reference is made to Figure 1 and Figure 7The battery cell dust removal mechanism can further comprise a dust removal outer cover 600 connected to the carrier plate 100 and covering the dust removal cover 310 and the two groups of ion air knives 320. It can be understood that when the dust removal outer cover 600 is provided, all the structures except the negative pressure dust removal pipeline 330 can be located in the dust removal outer cover 600, so that the external gas can be prevented from affecting the dust removal effect.
[0055] In the embodiment, the negative pressure dust removal pipeline 330 is arranged in the dust removal outer cover 600, so that the negative pressure dust removal pipeline 330 can be in communication with the dust removal holes in the dust removal outer cover 600.
[0056] The dust removal outer cover 600 is further provided with an air inlet 610, and the compressed gas outside the dust removal outer cover 600 can enter the dust removal outer cover 600 through the air inlet 610. After entering the dust removal outer cover 600, the gas first flows through the ion air knives 320 and then flows to the surface of the battery cell 10 in the dust removal cover 310.
[0057] In order to guide the gas of the air inlet 610 to the ion air knives 320, the dust removal outer cover 600 can be provided with two groups of air inlets 610 corresponding to the two groups of ion air knives 320, and the two groups of air inlets 610 can be arranged at the two ends of the dust removal outer cover 600 along the x direction. Each group of air inlets 610 can comprise two air inlets 610 arranged on the two sides of the dust removal outer cover 600 along the y direction, so that more compressed gas can enter the dust removal outer cover 600 through the air inlets 610 at the same time, thereby improving the dust removal efficiency.
[0058] The battery cell dust removal mechanism in the utility model has two groups of ion air knives, which can blow gas to the surface of the battery cell from both sides of the battery cell. Since the ion air knives can help to eliminate static electricity on the surface of the battery cell, the adsorption force of foreign matters on the surface of the battery cell is reduced, and the gas is more likely to blow the foreign matters off the surface of the battery cell. The dust removal cover can limit the random flow of the gas, and the negative pressure dust removal pipeline is arranged above the battery cell. After the gas is blown to the surface of the battery cell, the negative pressure dust removal pipeline can suck the gas in the dust removal cover. In this process, since the gas has blown the foreign matters on the surface of the battery cell, the foreign matters can enter the negative pressure dust removal pipeline together with the gas, thereby completing the dust removal work of the battery cell. When the battery cell is coated in the subsequent process, the foreign matters can be prevented from adhering to the surface of the battery cell to affect the coating yield, and the quality of the battery cell can be ensured.
[0059] Obviously, those skilled in the art can make various modifications and variations to the utility model embodiments without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model belong to the scope of the utility model claims and equivalent technologies, the utility model also intends to include these modifications and variations.
