Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a material clamping assembly and stacking platform. Background Technology

[0002] The lamination process refers to the process of cutting the positive and negative electrodes into small pieces and stacking them with the separator to form a small battery cell; then stacking the small battery cells in parallel to form a large battery cell.

[0003] During the lamination process, to prevent misalignment of the electrodes and diaphragms, they need to be pressed together. In existing technologies, a pressing mechanism is generally used to press and fix the stacked electrode layers and diaphragms. The pressing mechanism includes a pressing blade and a pressing blade drive mechanism; the pressing blade drive mechanism needs to drive the pressing blade through a series of movements such as rising, pressing down, flipping, and translating. Therefore, existing technologies typically use multiple servo motors or multiple cylinders, making the structure complex. Controlling multiple pressing blade mechanisms requires corresponding control of multiple pressing blade drive mechanisms, which is difficult. Utility Model Content

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

[0052] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., 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 the embodiments of this application 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 the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0053] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0054] Please see Figures 1 to 3 In the first aspect of this application, a material clamping assembly is provided, including: a first frame 10 and a second frame 20.

[0055] The first frame 10 and the second frame 20 are slidably connected relative to each other; the first frame 10 is provided with a plurality of first pressing knives 11; the second frame 20 is provided with a plurality of second pressing knives 21; the plurality of first pressing knives 11 and the plurality of second pressing knives 21 are arranged alternately.

[0056] In this embodiment, a first pressing blade 11 and a second pressing blade 21 can form a pair of pressing blade components for pressing materials; wherein, the material can be, for example, an electrode, a separator, or a battery cell composed of both. Correspondingly, multiple staggered first pressing blades 11 and second pressing blades 21 form multiple pairs of pressing blade components.

[0057] In a pair of pressing blade components, the distance between the first pressing blade 11 and the second pressing blade 21 is the pressing blade spacing. When the first frame 10 and the second frame 20 move relative to each other, the pressing blade spacing of multiple pairs of pressing blade components can be changed simultaneously, realizing the linkage control of multiple pairs of pressing blade components.

[0058] It should be noted that the relative movement of the first frame 10 and the second frame 20 can be achieved by driving the first frame 10, driving the second frame 20, or driving both the first frame 10 and the second frame 20 simultaneously. Taking the simultaneous driving of the first frame 10 and the second frame 20 as an example, the driver that adjusts the pressure knife spacing is called the spacing adjustment driver. Multiple spacing adjustment drivers can be included, and the output terminals of these drivers are respectively connected to the first frame 10 and the second frame 20. The spacing adjustment driver adjusts the pressure knife spacing by pushing the first frame 10 and the second frame 20 to move in opposite directions.

[0059] In practical applications, the pressing process of the pressure knife component on the material can include a vertical lifting process and a horizontal spacing adjustment process; the horizontal spacing adjustment process can be as described above; the vertical lifting process can be performed by a height adjustment driver such as a lifting cylinder. Specifically, the height adjustment driver is connected to the first frame 10 and / or the second frame 20, and drives the first frame 10 and the second frame 20 to lift synchronously when started, thereby controlling the height of the pressure knife component.

[0060] As can be seen from the above, in this embodiment, during the action control of the pressing and releasing of the material by the pressing knife component, the synchronous movement of multiple pressing knife components can be achieved by controlling the position of the first frame 10 and the second frame 20. Compared with the method of setting a drive mechanism for each of the multiple pressing knife components, the control difficulty can be effectively reduced and the complexity of the drive mechanism can be simplified.

[0061] In one embodiment, at least one of the first frame 10 and the second frame 20 is provided with an embedding block 12 and at least the other is provided with an embedding groove 22; the embedding block 12 can be slidably inserted into the embedding groove 22.

[0062] In this embodiment, the first frame 10 and the second frame 20 form a nested structure; the embedding block 12 and the embedding slot 22 can guide the relative sliding between the first frame 10 and the second frame 20.

[0063] Optionally, the second frame 20 is provided with an embedding block 12, and the first frame 10 is provided with an embedding slot 22.

[0064] Optionally, both the first frame 10 and the second frame 20 are provided with an embedding block 12, and both the first frame 10 and the second frame 20 are provided with an embedding slot 22.

[0065] In one embodiment, the first pressing knife 11 and the second pressing knife 21 have the same structure.

[0066] Please see Figure 3 Both the first pressing knife 11 and the second pressing knife 21 include: a blade 23 and a knife holder 24. The knife holder 24 is used to fix it to the first frame 10 or the second frame 20.

[0067] In one embodiment, the position of the first pressing knife 11 on the first frame 10 is adjustable, and / or the position of the second pressing knife 21 on the second frame 20 is adjustable.

[0068] Taking the adjustable position of the second pressure knife 21 on the second frame 20 as an example, please refer to [link / reference]. Figure 3The second pressure knife 21 can have a slotted hole 25 on its knife holder 24; the blade 23 is fixed to the knife holder 24 by an adjusting bolt 26 passing through the slotted hole 25. When the adjusting bolt 26 is loosened, the blade 23 can be adjusted along the length of the slotted hole 25, thereby adjusting the pressure knife spacing to adapt to materials of different sizes.

[0069] When the position of the first pressing knife 11 on the first frame 10 is adjustable, the adjustment method of the first pressing knife 11 is the same as that of the second pressing knife 21 described above, and will not be repeated here.

[0070] In another embodiment provided in this application, please refer to Figures 4 to 7 The material clamping assembly also includes: a third frame 30; the first frame 10 and / or the second frame 20 are slidably disposed on the third frame 30.

[0071] The third frame 30 serves as a support structure for the first frame 10 and / or the second frame 20, and is capable of being installed on the first frame 10 and / or the second frame 20.

[0072] Optionally, the second frame 20 is slidably disposed on the third frame 30; the first frame 10 is slidably disposed on the second frame 20, so that the first frame 10 and the second frame 20 can move relative to each other.

[0075] In one embodiment, the process of releasing the material by the first pressing knife 11 and the second pressing knife 21 may include rising and increasing the distance between the pressing knives; the process of releasing the material by the first pressing knife 11 and the second pressing knife 21 may include pressing down and decreasing the distance between the pressing knives. The rising and pressing processes of the first pressing knife 11 and the second pressing knife 21 can be achieved by controlling the lifting and lowering of the third frame 30.

[0076] In a more specific embodiment, the material clamping assembly further includes: a fourth frame 40; a plurality of telescopic columns 41 are provided on the fourth frame 40; and a third frame 30 is provided on the telescopic columns 41.

[0077] Multiple stacking platforms 70 can be provided on the fourth frame 40; multiple pressing blade components and multiple stacking platforms 70 correspond one-to-one. The stacking platforms 70 are used for placing materials; the pressing blade workpieces are set on the stacking platforms 70, and the first pressing blade 11 and the second pressing blade 21 are respectively set on both sides of the stacking platform 70.

[0078] The third frame 30 can be raised and lowered relative to the fourth frame 40 via the telescopic column 41, thereby driving the first frame 10, the second frame 20, the first pressure knife 11 and the second pressure knife 21 to rise and fall.

[0079] It should be noted that the first frame 10, the second frame 20 and the third frame 30 are all frame-shaped; the stacking platform 70 passes through the third frame 30, the first frame 10 and the second frame 20.

[0080] In one embodiment, see Figure 8 and Figure 9 The material clamping assembly also includes: a horizontal push block 50; a side push block 13 connected to the first frame 10 and the second frame 20; the horizontal push block 50 is slidably arranged in the horizontal direction; a side slope 51 is provided on the side of the horizontal push block 50; the side slope 51 abuts against the side push block 13 so that when the horizontal push block 50 slides, it drives the side push block 13 to move, thereby causing the first frame 10 and the second frame 20 to slide in opposite directions.

[0081] In this embodiment, the direction in which the horizontal pushing block 50 slides in the horizontal direction can be... Figure 8 The X-axis direction is in the middle; multiple first pressing knives 11 and multiple second pressing knives 21 are set along the Y-axis direction; wherein, the X-axis direction and the Y-axis direction are mutually perpendicular in the horizontal direction.

[0082] When the horizontal push block 50 slides, it can push the side push block 13 to slide, thereby pushing the first frame 10 and the second frame 20 to slide in opposite directions, thus achieving the adjustment of the pressure knife spacing.

[0083] Optionally, a transverse push driver 52 may be provided on the fourth frame 40; the output end of the transverse push driver 52 is connected to the transverse push block 50. The transverse push driver 52 can drive the transverse push block 50 to slide in the positive and negative directions of the X-axis, thereby realizing the adjustment of increasing or decreasing the pressure knife spacing.

[0084] Optionally, please refer to Figure 10 A spring 53 can be connected between the first pressing blade 11 and the second pressing blade 21. Specifically, when the horizontal pushing block 50 slides along the positive direction of the X-axis, it pushes the two side pushing blocks 13 away from each other, thereby causing the first pressing blade 11 and the second pressing blade 21 to move away from each other. When the horizontal pushing block 50 slides along the negative direction of the X-axis, the spring 53 pulls the first pressing blade 11 and the second pressing blade 21 closer together.

[0085] Optionally, please refer to Figure 11 The horizontal push block 50 is provided with a slide rail 54; the side push block 13 is provided with a rotatable side push wheel 14; the side push wheel 14 is slidably disposed within the slide rail 54, and both sides of the side push wheel 14 abut against the inner wall of the slide rail 54. When the horizontal push block 50 slides, the abutment position between the slide rail 54 and the side push wheel 14 changes, thereby driving the side push block 13. In this method, the horizontal push block 50 can increase or decrease the pressure knife spacing without the need for a spring 53.

[0086] It should be noted that in the embodiment where the spring 53 is provided above, the side push block 13 can also be provided with a rotatable side push wheel 14; the side push wheel 14 abuts against the side slope 51.

[0087] The side pusher 14 can reduce the friction between the side pusher block 13 and the horizontal pusher block 50, thereby improving the smoothness of the pressure knife spacing adjustment process.

[0089] Similarly, the longitudinal push block 60 slides horizontally in the X-axis direction. When the longitudinal push block 60 slides, it can push the lifting block 31 to rise and fall, thereby driving the third frame 30, the first frame 10, and the second frame 20 to rise and fall.

[0090] Optionally, a longitudinal pusher driver 62 may be provided on the fourth frame 40; the output end of the longitudinal pusher driver 62 is connected to the longitudinal pusher block 60.

[0091] Optionally, the lifting block 31 is provided with a rolling lifting wheel 32; the lifting wheel 32 abuts against the top inclined surface 61. The lifting wheel 32 can reduce the friction between the lifting block 31 and the longitudinal push block 60.

[0092] Optionally, multiple top inclined surfaces 61 can be provided on the longitudinal push block 60; correspondingly, multiple lifting blocks 31 can be provided on the third frame 30.

[0093] Optionally, a square groove 35 is provided on the third frame 30; the lifting block 31 is adjustablely disposed in the square groove 35; that is, the lifting block 31 can adjust its own position along the X-axis relative to the third frame 30, thereby adjusting the contact position between the lifting block 31 and the longitudinal push block 60, and realizing the adjustment of the lifting height of the third frame 30.

[0094] In one embodiment, the longitudinal push block 60 is synchronously slidably connected to the transverse push block 50.

[0095] Specifically, taking the action of the pressure knife component releasing material, including rising and increasing the pressure knife spacing, as an example; the longitudinal push block 60 and the transverse push block 50 can be configured such that when the longitudinal push block 60 slides in the positive X-axis direction, the transverse push block 50 slides in the positive X-axis direction simultaneously, and at this time the longitudinal push block 60 pushes the third frame 30 to rise, and the transverse push block 50 pushes the pressure knife spacing to increase, so as to realize the linkage between the two.
