Description

Technical Field

[0001] The present application relates to the technical field of battery cell production, and in particular to an aluminum boat support rod, an aluminum boat, a wind knife device and a slicing device. Background Art

[0002] The production process of battery cells generally requires an ALD (Atomic Layer Deposition) coating process. The ALD coating process includes a double-insertion process and a single-insertion process. In order to save the cost of ALD equipment, a double-insertion process is generally used. In the double-insertion process, two battery cells need to be inserted into one insertion slot of the bottom tooth of the aluminum boat.

[0003] In the prior art, during the ALD coating process on battery cells using a double insertion process, two battery cells in the same insertion slot are easily pressed against each other, resulting in poor air flow at the position where the two battery cells are pressed against each other, which can easily lead to uneven coating thickness on the opposite sides of the two battery cells, affecting the production quality of the battery cells.

[0004] It can be seen that in the prior art, when the double insertion process is used to perform ALD coating on the battery cell, the uneven coating thickness of the battery cell is a technical problem that needs to be solved urgently. Utility Model Content

[0006] In order to solve the above problems, the present application provides an aluminum boat support rod, the aluminum boat support rod comprising:

[0007] A rod body is formed with a plurality of insertion slots, the plurality of insertion slots are distributed along the central axis of the rod body, the bottom of the insertion slot has a separation protrusion, the separation protrusion separates the bottom of the slot into a first slot and a second slot, the first slot is used to insert one of the two battery cells in the insertion slot, and the second slot is used to insert the other of the two battery cells in the insertion slot.

[0008] In some embodiments, the width of the first slot is D1, the width of the second slot is D2, the thickness of the battery cell inserted in the insertion slot is D, D1 satisfies: D<D1<2D, and D2 satisfies: D<D2<2D.

[0009] In some embodiments, the opposite side walls of the insertion slot include an inclined wall and a vertical wall, the inclined wall is distributed at one end close to the slot opening of the insertion slot, the vertical wall is distributed at one end close to the bottom of the slot, and the height of the separation protrusion is flush with the height of the vertical wall.

[0010] In some embodiments, in a direction perpendicular to the central axis of the rod body, an extension dimension of the separation protrusion is smaller than an extension dimension of the bottom surface of the insertion groove.

[0011] In some embodiments, two adjacent vertical surfaces of the separation protrusion are connected by an arc surface.

[0012] The present application also provides an aluminum boat, the aluminum boat comprising:

[0013] Frame;

[0014] Any of the aluminum boat support rods as described above is arranged at the bottom of the frame;

[0015] A push rod is arranged on the top of the frame body, and the push rod has a plurality of top tooth grooves corresponding to the insertion grooves.

[0016] The present application also provides a wind knife device for use with the above-mentioned aluminum boat, the wind knife device comprising:

[0017] The air outlet mechanism includes at least two air outlets, which are distributed on both sides of the aluminum boat support rod. The air outlets are used to blow the two battery cells in each insertion slot to the first slot and the second slot respectively by moving relative to the aluminum boat along the central axis direction of the aluminum boat support rod.

[0018] In some embodiments, the air knife device further comprises:

[0019] The lifting mechanism includes a lifting tooth plate, and a plurality of lifting tooth grooves are distributed on the lifting tooth plate along the central axis direction of the aluminum boat support rod. The lifting tooth grooves include a first guide slope and a second guide slope relative to each other, and the first guide slope and the second guide slope are inclined in opposite directions. The lifting tooth grooves are used to eject the battery cells from the first slot and the second slot.

[0020] In some embodiments, the inclination angles of the first guiding slope and the second guiding slope relative to the vertical plane are both 45 degrees.

[0021] The present application also provides a slicing device for use in a double insertion process of an ALD process, the slicing device comprising:

[0022] The aluminum boat as described above is used to load the battery cells;

[0023] Any wind knife device as described above is used to blow the two battery sheets in each of the insertion slots in the aluminum boat to the first slot and the second slot respectively.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0042] See also Figures 1 to 4 The present application provides an aluminum boat support rod 10, which can be used in an aluminum boat 100 and is arranged at the bottom of the aluminum boat 100. The aluminum boat support rod 10 includes a rod body 11, and a plurality of insertion slots 12 are formed on the rod body 11. The plurality of insertion slots 12 are distributed along the central axis of the rod body 11. The bottom of the insertion slot 12 has a partitioning protrusion 13, and the partitioning protrusion 13 divides the slot body into a first insertion slot 141 and a second insertion slot 142. The first insertion slot 141 is used to insert one of the two battery cells 300 in the insertion slot 12, and the second insertion slot 142 is used to insert the other of the two battery cells 300 in the insertion slot 12.

[0043] In the embodiments of the present application, there is no limitation on the specific shape of the insertion slot 12. For example, in some embodiments, the two opposite side walls of the insertion slot 12 may include an inclined wall 121 and a vertical wall 122. The inclined wall 121 and the vertical wall 122 are connected to each other. The inclined wall 121 is distributed at one end close to the slot opening of the insertion slot 12, and the vertical wall 122 is distributed at one end close to the slot bottom of the insertion slot 12. The two opposite inclined walls 121 of the insertion slot 12 are inclined in opposite directions, so that the insertion slot 12 forms an open slot. When the two opposite side walls of the insertion slot 12 include a cleaning wall and a vertical wall 122, in some embodiments, the height of the separation protrusion 13 can be flush with the height of the vertical wall 122, but it is not limited thereto.

[0044] The first slot 141 and the second slot 142 are used to insert the two separated battery cells 300 in the insertion slot 12, respectively. Since the insertion slot 12 is distributed along the central axis of the rod body 11, the battery cells 300 are also arranged along the central axis of the rod body 11. It can be understood that the first slot 141 and the second slot 142 are also arranged along the central axis of the rod body 11. To ensure that the two battery cells 300 in the insertion slot 12 can be respectively divided into the first slot 141 and the second slot 142, in some embodiments, the width of the first slot 141 is D1, the width of the second slot 142 is D2, and the thickness of the battery cell 300 inserted in the insertion slot 12 is D, so that D1 satisfies: D<D1<2D, and D2 satisfies: D<D2<2D. It should be noted that the width of the first slot 141 and the second slot 142 refers to the size of the first slot 141 and the second slot 142 in the direction along the central axis of the support rod, and the thickness of the battery cell 300 inserted in the insertion slot 12 refers to the thickness of each battery cell 300 in the insertion slot 12. The width of the first slot 141 and the second slot 142 are both greater than the thickness of one battery cell 300 and less than the thickness of two battery cells 300. The width of the first slot 141 and the width of the second slot 142 can be equal or different. For example, in one embodiment, the thickness of the battery cell 300 is 0.125 mm, and the width of the first slot 141 and the width of the second slot 142 can both be 0.2 mm. It should be noted that the width of the bottom of the insertion slot 12 is generally wider. After the separation protrusion 13 separates the bottom of the slot into the first slot 141 and the second slot 142, the width of the upper surface of the separation protrusion 13 is generally greater than twice the thickness of the battery cell 300.

[0045] The separation protrusion 13 is formed at the bottom of the insertion groove 12. In some embodiments, the separation protrusion 13 can be a rectangular protrusion extending from the bottom surface of the insertion groove 12 in a direction perpendicular to the central axis of the rod body 11. Figure 3 As shown, the separation protrusion 13 can extend to both ends of the insertion groove 12 at the bottom of the insertion groove 12. Figure 4As shown, in the direction perpendicular to the central axis of the rod body 11, the extension dimension of the partition protrusion 13 is smaller than the extension dimension of the bottom surface of the insertion groove 12. When the extension dimension of the partition protrusion 13 is smaller than the extension dimension of the bottom surface of the insertion groove 12, the partition protrusion 13 can be distributed in the middle section of the bottom surface of the insertion groove 12. By making the extension dimension of the partition protrusion 13 smaller than the extension dimension of the bottom surface of the insertion groove 12, the processing difficulty of the insertion groove 12 is reduced, and the processing and manufacturing of the insertion groove 12 on the rod body 11 is facilitated.

[0046] like Figure 4 As shown, in some embodiments, since the battery cell 300 is placed through the insertion slot 12, in order to prevent the battery cell 300 from being broken by the edges of the rectangular protrusion when the wind knife device 200 blows the battery cell 300, the two adjacent vertical surfaces of the separation protrusion 13 can be connected by an arc surface.

[0047] The above-mentioned embodiment of the present application provides an aluminum boat support rod 10, which, when applied to the aluminum boat 100, is used to load battery cells 300 in the double insertion process of ALD coating. Since each insertion slot 12 on the aluminum boat support rod 10 is separated into a first slot 141 and a second slot 142, before coating the battery cells 300, the two battery cells 300 in each insertion slot 12 can be respectively divided into the first slot 141 and the second slot 142, thereby effectively avoiding the close fit of two battery cells 300 in one insertion, which leads to uneven coating thickness on the surface of the battery cell 300 and produces crescent marks, thereby ensuring the production quality of the battery cell 300.

[0048] like Figure 5 As shown, in other embodiments, the present application also provides an aluminum boat 100, which includes a frame 20, the aluminum boat support rod 10 in the above embodiment, and a top rod 30. The aluminum boat support rod 10 is arranged at the bottom of the frame 20, and the insertion groove 12 on the aluminum boat support rod 10 forms the bottom tooth groove of the aluminum boat 100. The top rod 30 is arranged at the top of the frame 20, and the top rod 30 has a top tooth groove corresponding to the insertion groove 12 on the aluminum boat support rod 10, and the upper and lower ends of the battery cell 300 are arranged in the aluminum boat 100 by cooperating with the top tooth groove and the bottom tooth groove.

[0049] The aluminum boat 100 provided in the present application adopts all technical solutions of all the embodiments of the above-mentioned aluminum boat support rod 10, and therefore has at least all the beneficial effects brought by the technical solutions of the embodiments of the above-mentioned aluminum boat support rod 10, which will not be described one by one here.

[0050] like Figure 6-8 As shown, in other embodiments, the present application also provides a wind knife device 200, which is used in conjunction with the above-mentioned aluminum boat 100 to blow the two battery cells 300 in each insertion slot 12 in the aluminum boat 100 to the first slot 141 and the second slot 142 respectively.

[0051] like Figure 6 As shown, the wind knife device 200 includes an air outlet mechanism 40, and the air outlet mechanism 40 includes at least two air outlets 43, and the two air outlets 43 are distributed on both sides of the aluminum boat support rod 10. The air outlet 43 is used to blow the two battery cells 300 in each insertion slot 12 to the first slot 141 and the second slot 142 respectively by moving relative to the aluminum boat 100 along the central axis direction of the aluminum boat support rod 10. The air outlet 43 on the air outlet mechanism 40 moves relative to the aluminum boat 100 along the central axis direction of the aluminum boat support rod 10, and the gas blown out of the air outlet 43 sweeps across each battery cell 300, and the gas will be blown between the two battery cells 300 in the same insertion slot 12. As the air outlet mechanism 40 moves, the two battery cells 300 will be brought to the corresponding slots under the action of wind pressure. It should be noted that since the battery cell 300 has been subjected to a texturing treatment before entering the ALD process, the surface of the battery cell 300 has a certain degree of roughness. Even if the two battery cells 300 in the same insertion slot 12 are close together, the probability of the two battery cells 300 being completely close together to form a vacuum state is extremely small. Therefore, when the driving mechanism 50 drives the air outlet mechanism 40 to sweep across the end faces of each battery cell 300, the gas blown out by the air outlet mechanism 40 can separate the two battery cells 300 that are close together.

[0052] When the wind knife device 200 slices the battery cells 300 in the aluminum boat 100, the air outlet mechanism 40 needs to move relative to the aluminum boat 100 along the central axis direction of the aluminum boat support rod 10. The driving mechanism 50 may drive the aluminum boat 100 to move, or the driving mechanism 50 may drive the air outlet mechanism 40 to move. In the embodiment of the present application, the driving mechanism 50 driving the air outlet mechanism 40 to move is used as an example for explanation.

[0053] In some embodiments, the wind knife device 200 also includes a driving mechanism 50. The driving mechanism 50 is used to drive the air outlet mechanism 40 to move along the central axis direction of the support rod. It can be understood that the driving mechanism 50 includes a moving component 51 for realizing linear movement, wherein the moving component 51 can be a cylinder component, a linear guide rail component or a screw slider component, but is not limited to this. In the embodiment of the present application, the moving component 51 is described as a linear guide rail component as an example. The moving component 51 includes a guide rail and a slider sliding along the guide rail, and the air outlet mechanism 40 can be arranged on the slider. It can be understood that the guide rail in the moving component 51 is arranged along the central axis of the support rod. In some embodiments, the driving mechanism 50 can also include a first lifting component 52, and the first lifting component 52 is used to drive the air outlet mechanism 40 to move closer to the aluminum boat 100 or away from the aluminum boat 100. It can be understood that the first lifting component 52 is also a linear moving component 51. The first lifting component 52 can also be a cylinder component, a linear guide rail component or a screw slider component, but is not limited to this. In the implementation of the present application, the first lifting component 52 is taken as a cylinder component for example for explanation. The cylinder body of the cylinder can be set on the slider of the moving component 51, and the air outlet mechanism 40 is set on the slider of the cylinder.

[0054] The air outlet mechanism 40 is used to blow the two battery cells 300 in each insertion slot 12 into the first slot 141 and the second slot 142 respectively. In some implementations, the air outlet mechanism 40 can be distributed below the aluminum boat 100, that is, the air outlet mechanism 40 blows air to each battery cell 300 from the bottom of the battery cell 300. Of course, in some embodiments, the air outlet mechanism 40 is distributed above the aluminum boat 100 in addition to being distributed below the aluminum boat 100, that is, the air outlet mechanism 40 in the wind knife device 200 blows air to the battery cell 300 from both above and below the battery cell 300 to ensure the separation effect of the two battery cells 300 in the insertion slot 12. It should be noted that when the air outlet mechanism 40 is distributed below and above the aluminum boat 100 at the same time, the moving direction of the air outlet mechanism 40 when moving along the aluminum boat support rod 10 should be synchronized. Of course, in some embodiments, the moving direction and moving speed of the air outlet mechanism 40 above and below the aluminum boat 100 can also be synchronized.

[0055] In the embodiments of the present application, the specific structure of the gas outlet mechanism 40 is not limited. For example, in some embodiments, the gas outlet mechanism 40 may include a connection block 41 and a gas outlet pipe 42. One end of the gas outlet pipe 42 forms a gas outlet 43 to blow air to the battery cell 300, and the other end is connected to the connection block 41. The connection block 41 is also connected to the air pump, so that the gas provided by the air pump can enter the gas outlet pipe 42 through the connection block 41, and then blow to the battery cell 300 from the gas outlet 43 of the gas outlet pipe 42. It should be noted that each gas outlet pipe 42 may form one gas outlet 43 or multiple gas outlets 43. In the embodiments of the present application, each gas outlet pipe 42 forms one gas outlet 43 as an example for description. In the embodiment of the present application, each air outlet mechanism 40 includes at least two air outlets 43, and the two air outlets 43 are distributed on both sides of the support rod. In this way, the battery cells 300 at both ends of each insertion slot 12 can be subjected to wind pressure, and the battery cells 300 are evenly stressed, so that the battery cells 300 can be blown into the corresponding slots more easily, and the even stress on the battery cells 300 can reduce the risk of battery cells 300 breaking. Figure 6 As shown, in some embodiments, the air outlet mechanism 40 may include four air outlets 43. When the air outlet mechanism 40 includes four air outlets 43, the four air outlets 43 are symmetrically distributed with the central axis of the support rod as the symmetry axis, ensuring that the battery cells 300 at both ends of the insertion slot 12 are evenly stressed. Of course, in order to prevent a battery cell 300 from being affected by the wind pressure of two air outlets 43 at the same time along the central axis of the support rod, the two air outlets 43 on each side of the support rod are arranged at intervals.

[0056] like Figure 7 and Figure 8As shown, in some embodiments, the wind knife device 200 also includes a lifting mechanism 60. The lifting mechanism 60 includes a lifting tooth plate 61, and a plurality of lifting tooth grooves 62 are distributed on the lifting tooth plate 61 along the central axis direction of the support rod. The lifting tooth groove 62 includes a first guide bevel 621 and a second guide bevel 622, and the first guide bevel 621 and the second guide bevel 622 are inclined in opposite directions. The lifting tooth groove 62 is used to eject the battery cell 300 from the first slot 141 and the second slot 142. It should be noted that in order to ensure that the first guide bevel 621 and the second guide bevel 622 can guide the battery cell 300 when the lifting tooth groove 62 lifts the battery cell 300, it can be understood that the first guide bevel 621 and the second guide bevel 622 are inclined in a direction away from each other from the bottom of the lifting tooth groove 62 to the opening of the lifting tooth groove 62. For example, in some embodiments, the first guide slope 621 and the second guide slope 622 are both inclined at an angle of 45 degrees relative to the vertical plane. When another batch of battery cells 300 to be coated is needed after the battery cells 300 are coated, the two battery cells 300 separated into the first slot 141 and the second slot 142 generally need to be closed. The lifting tooth plate 61 in the lifting mechanism 60 rises and can push the battery cell 300 out of the first slot 141 and the second slot 142 through the lifting tooth groove 62. Since the first guide slope 621 and the second guide slope 622 are both inclined, when the lifting tooth groove 62 lifts the battery cell 300 upward, the first guide slope 621 and the second guide slope 622 can drive the battery cell 300 to move in the horizontal direction while driving the battery cell 300 to move upward, thereby avoiding the problem of the battery cell 300 being broken due to the misalignment between the insertion slot 12 below the aluminum boat 100 and the top tooth groove structure above along the central axis of the support rod, thereby ensuring the production yield of the battery cell 300.

[0057] The lifting tooth plate 61 can be arranged between the two supporting rods corresponding to the battery cell 300. To ensure that the lifting tooth plate 61 stably lifts the battery cell 300, the lifting tooth plate 61 can be distributed with two rows of lifting tooth grooves 62 arranged along the central axis of the supporting rod. To achieve the lifting and lowering of the lifting tooth plate 61, it can be understood that the lifting mechanism 60 also includes a second lifting assembly 63, which can also be a cylinder assembly, a linear guide assembly or a screw slider assembly, but is not limited thereto.

[0058] like Fig. 9As shown, in some embodiments, the present application also provides a slicing device 1000, which is used in the double insertion process of the ALD (Atomic Layer Deposition) process. In the ALD process, before coating the battery cells 300 on the aluminum boat 100, the two battery cells 300 in an insertion slot 12 are separated by the slicing device 1000 to avoid close fitting of the two battery cells 300 in the same insertion slot 12.

[0059] The slicing device 1000 includes the aluminum boat 100 in the above embodiment and the wind knife device 200 in the above embodiment. The aluminum boat 100 is used to load the battery cells 300, and the wind knife device 200 is used to blow the two battery cells 300 in each insertion slot 12 in the aluminum boat 100 into the first slot 141 and the second slot 142 respectively.

[0060] like Figure 2 and Fig. 9As shown, the slicing device 1000 provided in the present application, when slicing the battery cell 300, first, the battery cell 300 needs to be placed in the aluminum boat 100, and two battery cells 300 are inserted in each insertion slot 12. It should be noted that in the ALD process, the two battery cells 300 placed in each insertion slot 12 may be close together. After being placed, the two battery cells 300 may both fall on the upper surface of the partition protrusion 13, or one of them may fall on the upper surface of the partition protrusion 13, and the other may fall in the first slot 141 or the second slot 142. Of course, it is also possible that the two battery cells 300 fall in the first slot 141 and the second slot 142 respectively. In practice, the two battery cells 300 in each insertion slot 12 generally fall on the upper surface of the partition protrusion 13. Then, the air outlet mechanism 40 is controlled to blow air, and at the same time, the driving mechanism 50 is controlled to drive the air outlet mechanism 40 to move in the first direction E along the central axis of the support rod, so as to blow the battery cell 300 near the first slot 141 in the insertion slot 12 into the first slot 141; and then the driving mechanism 50 is controlled to drive the air outlet mechanism 40 to move in the second direction F along the central axis of the support rod, so as to blow the battery cell 300 near the second slot 142 in the insertion slot 12 into the second slot 142, wherein the first direction E is opposite to the second direction F. Taking the air outlet mechanism 40 disposed below the aluminum boat 100 as an example, when the driving mechanism 50 drives the air outlet mechanism 40 to move in the first direction E or the second direction F along the central axis of the aluminum boat support rod 10, the air outlet 43 of the air outlet mechanism 40 sweeps the battery cells 300 in each insertion slot 12 from the bottom of the battery cell 300. The first slot 141 and the second slot 142 in each insertion slot 12 are distributed along the central axis of the rod body 11. In the direction along the central axis of the rod body 11, the direction from the second slot 142 to the first slot 141 is the first direction E, and the direction from the first slot 141 to the second slot 142 is the second direction F. The air outlet mechanism 40 moves in the first direction E to blow the battery cell 300 near the first slot 141 in the insertion slot 12 into the first slot 141, and the air outlet mechanism 40 moves in the second direction F to blow the battery cell 300 near the second slot 142 in the insertion slot 12 into the second slot 142. In the embodiment of the present application, the air outlet mechanism 40 moves in the first direction E to blow the battery cell 300 near the first slot 141 in the insertion slot 12 into the first slot 141 as an example for description.During the movement of the air outlet mechanism 40 in the first direction E, the gas is first blown into between the two battery cells 300 that are close to each other to separate the two battery cells 300. As the air outlet mechanism 40 moves in the first direction E, the gas will push the battery cell 300 close to the first slot 141 to move toward the first slot 141, so that the battery cell 300 close to the first slot 141 can be blown into the first slot 141. At the same time, as the air outlet mechanism 40 moves in the first direction E, there will be a certain amount of airflow between the battery cell 300 close to the first slot 141 and the side wall of the first slot 141 in the insertion slot 12. According to Bernoulli's principle, the battery cell 300 close to the first slot 141 will also move toward the first slot 141 under the action of negative pressure, effectively ensuring that the battery cell 300 close to the first slot 141 can be blown into the first slot 141.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
