[0002] In recent years, lithium-ion batteries have been widely used in many fields due to their excellent electrochemical performance. As the demand for lithium-ion batteries increases, people's quality requirements for lithium-ion batteries are also getting higher and higher.

[0003] In the lithium-ion battery manufacturing process, the battery electrodes produced in the slicing section are typically placed manually into storage boxes. These boxes consist of a base plate fixed to a frame and positioning posts at the four corners of the electrodes, forming a storage space. However, due to different battery applications, different sizes and models of electrodes often need to be produced, requiring adjustments to the positions of the positioning posts and the size of the storage space.

[0004] However, existing technologies are prone to deviations when adjusting the positioning columns, resulting in the adjusted storage space not being a perfect match with the electrode to be stored, which can lead to damage to the electrode during placement or storage. Therefore, there is an urgent need for an electrode collection device that can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an electrode collection device that ensures that the storage space enclosed by the positioning column after adjustment matches the size and height of the electrode, thereby preventing damage during the collection or storage of the electrode.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Electrode collection device, comprising:

[0008] The placement mechanism includes a base plate and a number of positioning posts, wherein the positioning posts and the base plate are arranged to form a storage space with an open end, and the position of the positioning posts relative to the base plate is adjustable;

[0009] The positioning mechanism includes positioning components, wherein the projection of each positioning component on the base plate corresponds to the same shape and size as the projection of different sized electrodes on the base plate; the positioning mechanism can be positioned on the base plate, and a plurality of positioning posts abut against the side wall of the positioning mechanism; the positioning components and the connecting components are detachably connected.

[0010] As an alternative, the positioning component includes two positioning plates, which are respectively connected to both ends of the connecting component along a first direction, the first direction being parallel to the positioning post.

[0011] As an optional solution, one of the two positioning plates includes a lower positioning plate, which extends into the storage space and contacts the base plate. The lower surface of the lower positioning plate is provided with a positioning protrusion, and the base plate is provided with a positioning groove. The positioning protrusion and the positioning groove are interlocked.

[0012] As an alternative, the center of the positioning protrusion coincides with the center of the positioning plate, and the center of the positioning groove coincides with the center of the base plate.

[0013] As an alternative, one of the two positioning plates also includes an upper positioning plate facing the open end of the storage space, and a gripping element is connected to the upper end of the upper positioning plate.

[0014] As an alternative, the connecting assembly includes a connecting plate, and two positioning plates of the same positioning assembly are detachably connected to both ends of the connecting plate.

[0015] As an optional solution, the positioning plate and the connecting plate are interlocked; and / or

[0016] The positioning plate and the connecting plate are connected by fasteners.

[0017] As an alternative, the connecting assembly includes at least two connecting plates, which are connected by an overlap member.

[0018] As an optional solution, the placement mechanism further includes an adjustment component, through which the positioning post is mounted on the base plate, and the adjustment component is used to adjust the position of the positioning post relative to the base plate.

[0021] The beneficial effects of this utility model are:

[0022] When using the electrode collection device of this invention, a positioning component corresponding to the size of the electrode to be collected is selected and installed on the connecting component to form a positioning mechanism that can simulate the size of the electrode. The positioning mechanism is then positioned on the base plate, and the positions of each positioning post relative to the base plate are adjusted so that each positioning post abuts against the side wall of the positioning plate. This ensures that the storage space formed by the positioning posts and the base plate matches the size and height of the electrode to be collected. The positioning mechanism is then removed from the storage space for electrode collection, preventing damage during collection or storage. Furthermore, by making the positioning component detachably connected to the connecting component, the connecting component can be used as a common component for positioning mechanisms of different sizes, thereby reducing the manufacturing cost of the electrode collection device.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] This embodiment provides an electrode collection device with a storage space that is adjustable in size, thereby enabling the collection of electrodes of different sizes. The electrode collection device ensures that the height of the storage space matches the height of the electrode after each adjustment, thus preventing damage to the electrode during placement or storage.

[0033] like Figure 1As shown, the electrode collection device includes a placement mechanism 10 and a positioning mechanism 20. The placement mechanism 10 includes a base plate 11 and several positioning posts 12 disposed on the upper side of the base plate 11. A storage space with an open end is formed between the positioning posts 12 and the base plate 11, which is used to store electrode sheets. The position of the positioning posts 12 relative to the base plate 11 is adjustable, thereby adjusting the size of the storage space and allowing for the storage of electrode sheets of different sizes. The positioning mechanism 20 includes a connecting component 21 and several positioning components 22. The projection of each positioning component 22 onto the base plate 11 corresponds to the same shape and size as the projection of electrode sheets of different sizes onto the base plate 11. The positioning mechanism 20 is positioned on the base plate 11, with the positioning posts 12 abutting against the sidewalls of the positioning components 22. The positioning components 22 are detachably connected to the connecting component 21.

[0034] When using the electrode collection device of this embodiment, a positioning component 22 corresponding to the size of the electrode to be collected is selected, and the positioning component 22 is installed on the connecting component 21 to form a positioning mechanism 20 that can simulate the size of the electrode. The positioning mechanism 20 is then positioned on the base plate 11, and the positions of each positioning post 12 relative to the base plate 11 are adjusted so that each positioning post 12 abuts against the side wall of the positioning component 22. This ensures that the storage space formed by the positioning posts 12 and the base plate 11 matches the size and height of the electrode to be collected. The positioning mechanism 20 is then removed from the storage space to collect the electrode, thus preventing damage during collection or storage. Furthermore, by making the positioning component 22 detachably connected to the connecting component 21, the connecting component 21 can be used as a common component for positioning mechanisms 20 of different sizes, thereby reducing the manufacturing cost of the electrode collection device.

[0035] like Figure 1 As shown, the positioning post 12 extends along the first direction, and the base plate 11 is parallel to the first plane perpendicular to the first direction. In this embodiment, the first direction is vertical, and the first plane is parallel to the horizontal plane. The positioning component 22 includes two positioning plates 220, which are respectively connected to the two ends of the connecting component 21 along the first direction (i.e., connected to the upper and lower ends of the connecting component 21). The projection of the positioning plate 220 on the first plane and the projection of the corresponding size electrode sheet on the first plane have the same shape and the same size, so that the positioning mechanism 20 can limit the positioning post 12 at both the upper and lower ends, ensuring that the cross-section of the final storage space along the vertical direction remains consistent.

[0036] In this embodiment, the placement mechanism 10 includes four positioning posts 12 arranged in a rectangular pattern. The cross-section of each positioning post 12 is approximately L-shaped. When the electrode is placed in the storage space, the four L-shaped positioning posts 12 are positioned at the four corners of the electrode, ensuring reliable positioning of the electrode. In this embodiment, the position of each positioning post 12 relative to the base plate 11 is adjustable in both the second and third directions. Both the second and third directions are parallel to the base plate 11 and perpendicular to each other.

[0037] In order to make the position of each positioning post 12 adjustable relative to the base plate 11, the placement mechanism 10 also includes an adjustment component 13. The positioning post 12 is mounted on the base plate 11 through the adjustment component 13, and the adjustment component 13 is used to adjust the position of the positioning post 12 relative to the base plate 11.

[0038] Specifically, the adjustment assembly 13 includes two mounting brackets 131 arranged opposite each other along a second direction, with two positioning posts 12 connected to each end of each mounting bracket 131 along a third direction. A first adjustment hole 112 extending along the second direction is provided on the base plate 11, and the mounting bracket 131 can be locked at any position in the first adjustment hole 112 by a first fastener. A second adjustment hole 1311 extending along a third direction is provided on the mounting bracket 131, and the positioning posts 12 can be locked at any position in the second adjustment hole 1311 by a second fastener. When adjusting the position of the positioning post 12 along the second direction, first loosen the first fastener to allow the mounting bracket 131 to move relative to the base plate 11 along the second direction. After the position of the positioning post 12 is adjusted (i.e., after the positioning post 12 abuts against the side wall of the positioning plate 220), tighten the first fastener again. When adjusting the position of the positioning post 12 along the third direction, first loosen the second fastener so that the positioning post 12 can move relative to the mounting bracket 131 (that is, relative to the base plate 11) along the third direction. After the position of the positioning post 12 is adjusted (that is, after the positioning post 12 abuts against the side wall of the positioning plate 220), tighten the second fastener again.

[0039] In this embodiment, each mounting bracket 131 is provided with three first adjustment holes 112, which are arranged at intervals along a third direction. Three first fasteners pass through the three first adjustment holes 112 and are connected to the mounting bracket 131, thereby ensuring the secure installation of the mounting bracket 131. It is understood that in other embodiments, each mounting bracket 131 may be configured with one, two, four, or more first adjustment holes 112. In other embodiments, two mounting brackets 131 may share the first adjustment holes 112, which is not limited here. Each positioning post 12 on the mounting bracket 131 is provided with two second adjustment holes 1311. Two second fasteners pass through the two second adjustment holes 1311 and are connected to the positioning post 12, thereby ensuring the secure installation of the positioning post 12. It is understood that in other embodiments, each positioning post 12 may be configured with one, three, or more second adjustment holes 1311. In other embodiments, two positioning posts 12 on the same mounting bracket 131 may also share the second adjustment holes 1311, which is not specifically limited here.

[0040] In this embodiment, as Figure 1 As shown, the adjustment assembly 13 also includes a guide member 132 and a guide slider (not shown in the figure). The guide slider is connected to the end of the mounting bracket 131 along a third direction. The guide member 132 has a guide hole 1321 extending along a second direction. The guide slider and the guide hole 1321 on the guide member 132 cooperate to form a sliding guide structure. When adjusting the position of the mounting bracket 131 along the second direction, the guide slider will slide within the guide hole 1321, thereby realizing the adjustment and guidance of the mounting bracket 131 and ensuring that the mounting bracket 131 is accurately adjusted along the second direction. In this embodiment, each guide member 132 is provided with two guide holes 1321, and the guide sliders at the ends of the two mounting brackets 131 slide in cooperation with the two guide holes 1321 respectively. Furthermore, guide sliders are provided at both ends of the mounting bracket 131 along the second direction. The adjustment assembly 13 includes two guide members 132, which are respectively provided at both ends of the mounting bracket 131 along the third direction and slide in cooperation with the guide sliders at both ends of the mounting bracket 131 along the third direction.

[0041] like Figure 1 and Figure 2As shown, of the two positioning plates 220 of the positioning assembly 22, one is an upper positioning plate 221 and the other is a lower positioning plate 222. The upper positioning plate 221 faces the open end of the storage space, and the lower positioning plate 222 extends into the storage space and contacts the base plate 11. A positioning protrusion 223 is provided on the lower surface of the lower positioning plate 222, and a positioning groove 111 is provided on the base plate 11. The positioning protrusion 223 and the positioning groove 111 are interlocked. Through the cooperation of the positioning protrusion 223 and the positioning groove 111, the placement position of the positioning mechanism 20 on the base plate 11 is defined, so that the storage space enclosed by the positioning post 12 is located in an appropriate position on the base plate 11, thereby ensuring that the electrode sheet placed subsequently is located in an appropriate position on the base plate 11.

[0042] In this embodiment, the center of the positioning protrusion 223 coincides with the center of the positioning plate 220, and the center of the positioning groove 111 coincides with the center of the base plate 11. This ensures that the positioning protrusion is positioned in the middle of the base plate 11 after being placed on the base plate 11, thereby ensuring that the storage space enclosed by the positioning post 12 is located in the middle of the base plate 11, and further ensuring that the placed electrode is located in the middle of the base plate 11.

[0043] like Figure 1 As shown, a gripper 23 is connected to the upper end of the upper positioning plate 221. By providing the gripper 23, it is convenient to remove the positioning mechanism 20 from the storage space after adjusting the position of the positioning post 12, so that the electrode sheet can be placed into the storage space subsequently. Optionally, in this embodiment, the gripper 23 is a U-shaped part; in other embodiments, the gripper 23 can also be an L-shaped part, a ring part, etc., and no specific limitation is made here.

[0044] like Figure 1 As shown, the connecting component 21 includes a connecting plate 211. Two positioning plates 220 of the same positioning component 22 are detachably connected to both ends of the connecting plate 211. The connecting plate 211 can not only connect the two positioning plates 220, but also help reduce the weight of the entire positioning mechanism 20 and improve the convenience of using the electrode collection device.

[0045] In this embodiment, the connecting component 21 includes at least two connecting plates 211. The at least two connecting plates 211 provide more stable support for the two positioning plates 220. In this embodiment, the connecting component 21 includes two connecting plates 211; in other embodiments, the connecting component 21 may also have three or more connecting plates 211, which is not specifically limited here.

[0046] In some embodiments, at least two connecting plates 211 are connected by an overlap member (not shown in the figure). The overlap member not only improves the structural strength of the entire connecting assembly 21, but also allows the connecting assembly 21 to form a single unit, thus facilitating both placement and connection with the positioning assembly 22. It is understood that when the connecting assembly 21 has two or more connecting plates 211, it is sufficient to ensure that the upper end of at least one connecting plate 211 is connected to the upper positioning plate 221 and the lower end of at least one connecting plate 211 is connected to the lower positioning plate 222.

[0047] In some embodiments, the positioning plate 220 and the connecting plate 211 are interlocked. Specifically, of the upper end of the connecting plate 211 and the upper positioning plate 221, one has a mounting protrusion and the other has a mounting groove, with the mounting protrusion interlocking into the mounting groove. Of the lower end of the connecting plate 211 and the lower positioning plate 222, one has a mounting protrusion and the other has a mounting groove, with the mounting protrusion interlocking into the mounting groove.

[0048] In some embodiments, the positioning plate 220 and the connecting plate 211 are connected by fasteners. Specifically, for the upper positioning plate 221, the fastener passes through the upper positioning plate 221 and is threaded to the upper end of the connecting plate 211. For the lower positioning plate 222, the fastener passes through the lower positioning plate 222 and is threaded to the lower end of the connecting plate 211. It should be noted that the lower surface of the lower positioning plate 222 is provided with a countersunk groove to accommodate the end of the fastener, thereby ensuring that the lower surface of the lower positioning plate 222 is flat so as to make flat contact with the base plate 11.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. For those skilled in the art, based on the concept of this utility model, there will be changes in the specific implementation methods and application scope. The content of this specification should not be construed as a limitation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
