Description

Technical Field

[0001] This utility model belongs to the technical field of battery production equipment, specifically, it relates to a formation cabinet channel plate assembly and a formation cabinet. Background Technology

[0002] The formation process of pouch cells usually adopts a pressure formation process, which involves creating a gap between two adjacent channel plates to place the cells. By applying pressure to the channel plates, the cells are squeezed from both sides, thereby achieving formation under pressure.

[0003] To facilitate cell placement, the channel plate itself is designed as a sliding structure. Gaps inevitably exist between the components. Even slight offsets in cell placement can lead to significant tilting of the channel plate within a single formation fixture. Furthermore, for horizontal formation cabinets, base support materials are typically added between the channel plates to secure the cells and ensure stability. However, base support materials of the same specifications cannot accommodate the formation needs of cells of different sizes. Cells may shift upwards due to insufficient base support material length, or downwards due to excessive length. This uneven stress on the channel plate during pressurization further exacerbates the tilting, resulting in inconsistent cell thickness and even damage due to uneven pressure, significantly impacting product quality and formation efficiency. While existing formation cabinets can replace base support materials of different sizes to adjust the relative position between the cells and the channel plate, these methods significantly increase the workload of formation operators and cell production costs, hindering the development of automated battery production.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] In order to at least solve one of the problems in the prior art, this utility model provides a formation cabinet channel plate assembly, which includes alternating first channel plates and second channel plates, with battery cells sandwiched between the first channel plates and second channel plates, and limiting components provided on the first channel plates and second channel plates respectively. The limiting components are connected to the first channel plates and second channel plates, forming a stable isosceles triangle support between the first channel plates and second channel plates, thereby ensuring that the first channel plates and second channel plates are always in a parallel state.

[0006] This utility model also provides a formation cabinet using the above-mentioned channel plate assembly. Since the adjacent channel plates always remain parallel, even if the cell shifts, the channel plate will not tilt due to uneven force, ensuring the smooth progress of formation and avoiding deformation and damage to the cell during the formation process.

[0007] To achieve the above objectives, the first aspect of this utility model provides a chemical formation cabinet channel plate assembly, including alternating first and second channel plates, and a limiting component connected to the first and second channel plates. The first and second channel plates have parallel circuit boards spaced apart. The limiting component is positioned to avoid the area between the two circuit boards and includes a first limiting rod and a second limiting rod. The first and second limiting rods are intersected and of equal length, connected to the first channel plate at their midpoint, and rotatably mounted relative to the first channel plate with the connection point as an axis. During rotation, the projection of the first channel plate onto the plane of the first channel plate is always parallel to the circuit board. The two ends of the first and second limiting rods are slidably connected to the adjacent second channel plates, respectively.

[0008] Furthermore, the first channel plate has a through-hole first limiting port, which is parallel to the circuit board and has a length greater than that of the first limiting rod and the second limiting rod. A rotating shaft is provided inside the first limiting port, and the first limiting rod and the second limiting rod are rotatably connected to the rotating shaft.

[0009] Furthermore, the number of first limiting ports is the same as that of the limiting components and their positions are opposite. A first partition plate is also provided inside the first limiting port. The first partition plate is parallel to the circuit board and is located inside the first limiting port to divide the first limiting port. The first limiting rod and the second limiting rod are located on both sides of the first partition plate, respectively.

[0010] Furthermore, the second channel plate has a through-hole second limiting port, which is parallel to the circuit board. The projection of the rotation axis on the first channel plate is located inside the second limiting port and shares a symmetrical axis with the second limiting port. The first limiting rod and the second limiting rod are slidably connected to the second channel plate along the length direction of the second limiting port, and the sliding areas are located on both sides of the projection of the rotation axis.

[0011] Furthermore, the second channel plate also includes a slide rail located within the second limiting port. The slide rail is provided with two slide rods that can slide along the slide rail. The ends of the first limiting rod and the second limiting rod are respectively connected to different slide rods and are rotatably arranged relative to the slide rods with the slide rods as the axis.

[0012] Alternatively, as an alternative to the above solution, the second limiting port is provided with two sets of slide rails, which are symmetrically arranged on both sides of the horizontal axis of the second limiting port. Each set of slide rails is provided with a slide rod that can be slidably arranged along the slide rail. The first limiting rod and the second limiting rod are rotatably connected to the slide rods located in different slide rails.

[0013] Furthermore, the limiting component also includes a second partition plate, which is parallel to the circuit board and is disposed in the second limiting opening to divide the second limiting opening. The second partition plate is provided with a through hole of the same length as the slide rail for the slide rod to pass through.

[0014] Alternatively, two sets of slide rails can be installed on both sides of the second partition plate, with each set of slide rails having a slide rod that can slide along the slide rail.

[0015] Furthermore, the first and second limiting rods located on the same side of the second channel plate are respectively connected to both sides of the second partition plate.

[0016] Furthermore, the limiting components are arranged in pairs, located on opposite sides of the first channel plate and the second channel plate, respectively, with the circuit board located between the two limiting components.

[0017] The second aspect of this utility model provides a formation cabinet, including extrusion plates that are parallel to each other, sliding columns that are perpendicular to the extrusion plates, and a channel plate assembly as described above, which is disposed between the two extrusion plates. The first channel plate and the second channel plate in the channel plate assembly are parallel to the extrusion plates and are slidably disposed along the sliding columns in cooperation with them. The extrusion plates are used to pressurize the battery cells sandwiched between the first channel plate and the second channel plate by extruding the channel plate assembly from both sides of the channel plate assembly.

[0018] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0019] 1. The first and second limiting rods are of equal length and are arranged in an intersecting manner. When the first and second channel plates are squeezed and move closer to each other, it can better ensure that the two are always in a parallel state, effectively avoiding damage to the battery cell due to the two not being parallel.

[0020] 2. The first channel plate and the second channel plate are respectively provided with a first limiting port and a second limiting port. The rotating shaft and the slide rail are respectively located in the first limiting port and the second limiting port, which has higher stability compared to the first channel plate and the second channel plate. The first limiting port and the second limiting port are provided with a first partition plate and a second partition plate. While further improving the limiting stability of the limiting component, the first limiting rod and the second limiting rod are located on both sides of the first partition plate and the second partition plate, respectively, which can avoid interference between the first limiting rod and the second limiting rod during rotation, reduce the rotation resistance of the first limiting rod and the second limiting rod, and improve the accuracy of the pressurization control of the formation cabinet.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] It should be noted first that, in order to facilitate understanding of the present invention, the following embodiments will be described using a horizontal formation cabinet as an example.

[0031] This utility model provides a chemical formation cabinet channel plate assembly, such as Figures 1 to 5As shown, the device includes alternating first channel plates 1 and second channel plates 2. The first channel plates 1 and 2 have protruding wings on both sides near their tops. Sliding holes perpendicular to the first channel plates 1 and 2 are formed on the wings, and these sliding holes are used to engage with horizontally arranged sliding posts (not shown in the figure). This allows the first channel plates 1 and 2 to slide while also limiting their relative height in the vertical direction. The first channel plates 1 and 2 have paired circuit boards 7. In one embodiment of this invention, the circuit boards 7 on the first channel plates 1 and 2 are arranged vertically... The axis of symmetry is set symmetrically, and the limiting component avoids the circuit board 7. It includes a first limiting rod 3 and a second limiting rod 4. The first limiting rod 3 and the second limiting rod 4 are intersected and of equal length. They are connected to the first channel plate 1 from the midpoint and can be rotated relative to the first channel plate 1 with the connection point as the axis. During the rotation, the projection on the plane where the first channel plate 1 is located is always parallel to the circuit board 7. The two ends of the first limiting rod 3 and the second limiting rod 4 are respectively slidably connected to the adjacent second channel plate 2. Thus, the adjacent first channel plate 1 and second channel plate 2 can always remain parallel under the action of the limiting component, avoiding the tilting of the first channel plate 1 and the second channel plate 2 due to the battery cell not being placed in the center.

[0032] A set of limiting components includes a first limiting rod 3 and a second limiting rod 4. As one embodiment of this utility model, only one set of limiting components is provided between adjacent first channel plates 1 and second channel plates 2. In this case, the first limiting rod 3 and the second limiting rod 4 are respectively provided on both sides of the first channel plate 1 and the second channel plate 2. Alternatively, two sets of limiting components can be provided. In this case, the two sets of limiting components are respectively provided on both sides of the first channel plate 1 and the second channel plate 2. This setting method can better keep the first channel plate 1 and the second channel plate 2 parallel to each other.

[0033] The present invention will now be described in further detail with reference to specific embodiments.

[0034] Example 1

[0035] As an embodiment of the present invention, this embodiment provides a chemical forming cabinet channel plate assembly. The channel plate assembly includes a plurality of first channel plates 1 and second channel plates 2 arranged alternately along the length direction of the sliding column. For ease of explanation, one of the first channel plates 1 and two second channel plates 2 located on both sides of it are used as examples. Only one set of limiting components is provided on the side of the first channel plate 1 and the second channel plate 2, wherein the first limiting rod 3 and the second limiting rod 4 are respectively provided on the opposite sides of the first channel plate 1 and the second channel plate 2.

[0036] In this embodiment, as Figure 1 and Figure 2As shown, the first channel plate 1 has a rotating shaft 11 protruding horizontally. The two rotating shafts 11 are coplanar with the first channel plate 1 and symmetrically arranged on both sides of the first channel plate 1. The first limiting rod 3 and the second limiting rod 4 are both straight rods with the same length. They are respectively provided with shaft holes at the midpoint for the rotating shafts 11 to pass through, and cooperate with the rotating shafts 11 to achieve a rotating connection. At this time, the rotation planes of the first limiting rod 3 and the second limiting rod 4 are parallel to each other and are both vertical planes perpendicular to the first channel plate 1. The two ends of the first limiting rod 3 and the second limiting rod 4 are respectively connected to the second channel plate 2 and can be slidably arranged relative to the second channel plate 2 on the plane where the second channel plate 2 is located. At this time, the projections of the first limiting rod 3 and the second limiting rod 4 on any rotation plane intersect each other. The projections of the first limiting rod 3, the second limiting rod 4 and the second channel plate on any rotation plane always form an isosceles triangle with the projection of the second channel plate 2 as the base.

[0037] Specifically, the second channel plate 2 is the same size and shape as the first channel plate 1. The ends of the first limiting rod 3 and the second limiting rod 4 are slidably connected to the two sides of the second channel plate 2 in the horizontal direction. As one embodiment of this invention, the two sides of the second channel plate 2 have slide rails 5 arranged in the vertical direction. The slide rails 5 are provided with slide rods 6 that can slide in the vertical direction. One end of the slide rod 6 that extends into the slide rail 5 is provided with a pulley (not shown in the figure) that cooperates with the slide rail 5. The ends of the first limiting rod 3 and the second limiting rod 4 are connected to the part of the slide rod 6 that protrudes from the slide rail 5 and are rotatably arranged with the slide rod 6 as the axis.

[0038] Example 2

[0039] As another embodiment of the present invention, the difference between this embodiment and the first embodiment is that a set of limiting components are respectively provided on both sides of the first channel plate 1 and the second channel plate 2.

[0040] In this embodiment, as Figure 3 As shown, the two sets of limiting components are rotatably connected to the rotating shafts 11 on both sides of the first channel plate 1, that is, a first limiting rod 3 and a second limiting rod 4 are provided on both sides of the first channel plate 1, and the first limiting rod 3 and the second limiting rod 4 on both sides of the first channel plate 1 are arranged crosswise; the shape and size of the second channel plate 2 are the same as those of the first channel plate 1, and a vertically arranged slide rail 5 is provided on the side of the second channel plate 2. Two slidable slide rods 6 are provided in the slide rail 5. The ends of the first limiting rod 3 and the second limiting rod 4 are respectively connected to the two slide rods 6 and are rotatably arranged with the slide rods 6 as the axis.

[0041] Furthermore, in this embodiment, the projection of the rotation shaft 11 on the plane of the first channel plate 1 onto the plane of the second channel plate 2 coincides with the horizontal axis of symmetry of the slide rail 5, that is, the distances from both ends of the slide rail 5 to the projection of the rotation shaft 11 are the same, and thus the displacement distances of the slide rod 6 connected to the first limiting rod 3 and the second limiting rod 4 are the same during the backward movement. Furthermore, in order to avoid interference and obstruction between the two slide rods 6 in the same slide rail 5, which would affect the movement of the first channel plate 1 and the second channel plate 2, as an implementation of this embodiment, the second channel plate 2 has two symmetrically arranged slide rails 5, and the axis of symmetry of the two slide rails 5 coincides with the projection of the rotation shaft 11 onto the plane of the second channel plate 2.

[0042] Example 3

[0043] As another embodiment of the present invention, this embodiment is further improved on the basis of embodiment two as follows.

[0044] In this embodiment, as Figure 4 As shown, the circuit boards 7 on the first channel plate 1 and the second channel plate 2 are arranged close to the two horizontal edges and are spaced apart from the horizontal edges. The circuit boards 7 are cut out between the adjacent side edge and the first channel plate 1 and the second channel plate 2 to form a first limiting port 12 and a second limiting port 21, respectively. The first limiting port 12 and the second limiting port 21 are positioned opposite each other. The two sets of limiting components are respectively arranged in the areas defined by the first limiting port 12 and the second limiting port 21 on both sides of the first channel plate 1 and the second channel plate 2.

[0045] Specifically, the rotating shaft 11 is located within the first limiting port 12. The first limiting rod 3 and the second limiting rod 4 in the same limiting assembly are located within the same first limiting port 12 and are rotatably connected to the rotating shaft 11. To improve the rotational flexibility of the first limiting rod 3 and the second limiting rod 4, the length of the first limiting port 12 is greater than the length of the first limiting rod 3 and the second limiting rod 4. The projection of the rotating shaft 11 in the first limiting port 12 onto the plane of the second channel plate 2 is located within the second limiting port 21 and coincides with the horizontal axis of symmetry of the second limiting port 21. The slide rail 5 is located within the second limiting port 21, and the slide rod 6 is slidably disposed within the second limiting port 21. The ends of the first limiting rod 3 and the second limiting rod 4 extend into the second limiting port 21 and are rotatably connected to the slide rod 6. Furthermore, to avoid interference between the first limiting rod 3 and the second limiting rod 4, an isolation unit is also provided on the rotating shaft 11. The isolation unit is sleeved on the rotating shaft 11 and located within the first limiting rod 3. The isolation unit covers the surface of the rotating shaft 11 along its length direction. It prevents the first limiting rod 3, the second limiting rod 4, and the inner wall of the first limiting opening 12 from colliding with each other, thus avoiding impact on the limiting effect on the first channel plate 1 and the second channel plate 2. It also prevents the first limiting rod 3 and the second limiting rod 4 from shaking. In this embodiment, the isolation unit is a smooth metal gasket. In other embodiments, the isolation unit can be a glass or polymer material (e.g., polytetrafluoroethylene), or other existing devices commonly used in the art to reduce friction. Furthermore, the isolation unit can also be a coating attached to the first limiting rod 3, the second limiting rod 4, and the inner wall of the first limiting opening 12.

[0046] Example 4

[0047] As another embodiment of the present invention, this embodiment is further improved on the basis of embodiment three as follows.

[0048] In this embodiment, as Figure 5 As shown, a first partition plate 13 is also provided in the first limiting port 12. The first partition plate 13 is parallel to the circuit board 7 set on the first channel plate 1, that is, the first partition plate 13 is vertically set in the first limiting port 12, dividing the first limiting port 12 into two parts. The rotating shaft 11 passes through the first partition plate 13 and is set in the first limiting port 12. The first limiting rod 3 and the second limiting rod 4 are respectively set on both sides of the first partition plate 13. This arrangement avoids interference between the first limiting rod 3 and the second limiting rod 4 while supporting the rotating shaft 11, preventing the rotating shaft 11 from bending and deforming, and improving the service life of the limiting assembly.

[0049] Furthermore, in this embodiment, the second limiting port 21 is also provided with a second partition plate 22. The second partition plate 22 is also arranged parallel to the circuit board 7 on the second channel plate 2, dividing the second limiting port 21 into two parts. Slide rails 5 and slide rods 6 that cooperate with slide rails 5 are respectively provided on both sides of the second partition plate 22. The ends of the first limiting rod 3 and the second limiting rod 4 are respectively rotatably connected to the slide rods 6 located on different sides of the second partition plate 22. More specifically, as an implementation of this embodiment, the second limiting rod 4 is provided with a through hole of the same length as the slide rail 5 and opposite in position. The slide rod 6 passes through the slide rail 5. The first limiting rod 3 and the second limiting rod 4 are respectively rotatably connected to the part of the slide rod 6 located on one side of the second partition plate 22. The part of the slide rod 6 not covered by the first limiting rod 3 and the second limiting rod 4 is also provided with an isolation unit. Preferably, the isolation unit is symmetrically arranged on both sides of the first limiting rod 3 and the second limiting rod 4, so that the first limiting rod 3 and the second limiting rod 4 are respectively centrally located in the part of the second limiting port 21 separated by the second partition plate 22.

[0050] In other embodiments, two slide rails 5 can be symmetrically arranged on both sides of the second partition plate 22. The first limiting rod 3 and the second limiting rod 4 cooperate with the slide rail 5 located above one side of the second partition plate 22 and the slide rail 5 located below the other side of the second partition plate 22, respectively. Alternatively, the first limiting rod 3 and the second limiting rod 4 can cooperate with two slide rails 5 located on the same side of the second partition plate 22, respectively, and the other side cooperates with another set of limiting components. In this case, a part of the second limiting port 21 located on one side of the second partition plate 22 is aligned with the first limiting port 12, and the other side is aligned with the first limiting port 12 on another first channel plate 1. The two adjacent sets of limiting components are staggered.

[0051] This utility model also provides a formation cabinet having the above-mentioned channel plate assembly, as detailed below.

[0052] Example 5

[0053] As another embodiment of the present invention, this embodiment provides a formation cabinet having the channel plate assembly as described in Embodiment 4.

[0054] The formation cabinet includes two vertically arranged extrusion plates (not shown in the figure) and a sliding column (not shown in the figure) arranged perpendicular to the two extrusion plates. The channel plate assembly is located between the two extrusion plates. The first channel plate 1 and the second channel plate 2 are arranged alternately along the length of the sliding column. The two extrusion plates extrude the first channel plate assembly from both ends to achieve pressure formation of the cell.

[0055] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
