[0033] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments.
[0034] In battery material testing, the quality of the electrode has a certain impact on the accuracy of the battery test data. Therefore, it is necessary to eliminate the influence of these factors as much as possible during battery production to ensure the accuracy of the battery test results.
[0035] When cutting battery electrodes, due to the mechanical properties of battery materials, it is easy for material to fall off at the edge of the electrode, causing the electrode to fail to meet the requirements of use and become waste, or affecting the test results of the battery.
[0036] In addition, when testing batteries, different specifications of the battery will usually require different sizes of pole pieces, which requires the preparation of pole piece cutting tools of various specifications, increasing the testing cost and making management and use inconvenient.
[0037] Based on the current needs and problems in battery testing, in some embodiments, a button battery electrode sheet cutting tool is used. Figure 1 ,include:
[0038] The loading assembly includes two hinged force arms, which form a lever structure similar to a pliers. When a force is applied at one end, a larger force can be provided at the other end.
[0039] The cutting assembly includes two punching modules arranged opposite to each other, and the two punching modules are used for punching the pole pieces to cut the pole pieces into specific shapes and specifications;
[0040] A guide assembly is used to limit the movement direction of the punching and cutting dies so that the two punching and cutting dies can only move along the punching direction;
[0041] Among them, one punching module is connected to one end of one of the lever arms, and the other punching module is connected to one end of the other lever arm. Based on the connection method between the punching module and the lever arm, the two lever arms can drive the two punching modules to move relative to each other and apply the force required for punching to the punching modules.
[0042] In this way, during the cutting operation, the lever force provided by the force arm can be used to provide the cutting assembly with the punching force required for pole piece cutting, making the cutting operation convenient; and through the guide assembly and the connection structure adopted between the force arm and the punching module, the punching module can only move along the punching direction during the cutting process, so as to avoid the current collector wrinkles or pole piece powder falling caused by the cutting operation, thereby ensuring the cutting quality of the pole piece.
[0043] In order to facilitate the description of the button battery electrode cutting tool in this application, Figure 1 , the two force arms are respectively referred to as the first force arm 11 and the second force arm 12, Figure 1 The first force arm 11 is located above the second force arm 12; the two punching die sets are respectively referred to as the first punching die set 21 and the second punching die set 22; Figure 1 The first punching die set 21 is located above the second punching die set 22 .
[0044] like Figure 1 As shown, one end of the first lever arm 11 is connected to the second punching die set 22 , and one end of the second lever arm 12 is connected to the first punching die set 21 .
[0045] In some embodiments, as a connection structure between a punching die set and a force arm that can realize the above functions, the second punching die set 22 can be fixedly connected to the first force arm 11, and the first punching die set 21 can be set to a sliding fit connection structure with the second force arm 12. In this way, when a force is applied to the punching die set through the two force arms, under the limiting action of the guide assembly, the first punching die set and the second punching die set can move relative to each other in the punching direction, and a punching force is applied to the two punching die sets through the two force arms.
[0046] In some embodiments, as another connection structure between the punching die set and the lever arm that can achieve the above functions, the two punching die sets and the two lever arms can be set as a sliding fit connection structure, which can also achieve the above functions and actions.
[0047] In some embodiments, as a structure for realizing a sliding fit connection between the lever arm and the punching die set, such as Figure 1 and Figure 2 As shown, a sliding plate 26 is provided on the punching die set, and the sliding plate 26 and the punching die set are slidably matched, so that the sliding plate can slide on the punching die set in the horizontal direction, and the lever arm connected to the punching die set is hingedly connected to the sliding plate. Here, a structure in which the punching die set is slidably matched with one lever arm, and another punching die set is fixedly connected with another lever arm is taken as an example. Based on the cutting tool of this structure, when a clamping force is applied to the lever arm, the first lever arm and the second lever arm respectively drive the two punching die sets to move in a direction close to each other. At this time, under the limiting effect of the guide assembly, the two punching die sets move in the punching direction; at the same time, the first lever arm provides an upward force for the second punching die set, and the second lever arm provides a downward force for the first punching die set through the sliding plate, thereby completing the punching of the pole piece.
[0048] It is easy to imagine that when the two force arms and the punching module respectively adopt this sliding fit connection structure, the punching of the pole piece can also be achieved, which will not be elaborated here.
[0049] Of course, based on this sliding fit connection structure, there can be other conventional alternatives, such as sliding fit connection of one end of the lever arm with the punching module on both sides through a hinge shaft, which can also achieve the above-mentioned punching operation.
[0050] In some embodiments, Figure 2 As shown, the guide assembly may include four guide pillars 30, each of which is respectively arranged at the four corners of the punching and cutting module. One end of the guide pillar 30 is fixedly connected to the second punching and cutting module 22, and the other end of the guide pillar 30 is slidably connected to the first punching and cutting module 21, thereby limiting the first punching and cutting module and the second punching and cutting module to move only along the guide pillar, thereby playing the role of guiding and limiting the punching and cutting module.
[0051] In some embodiments, Figure 2 The first punching die set 21 includes a template 23 and a male die 24 disposed on the template, and the second punching die set 22 includes a template 23 and a female die 25 disposed on the template. Figure 2 and Figure 3The punching head is provided on the punch 24, and the punching hole matched with the punching head is provided on the die 25. During the pole piece cutting operation, the pole piece to be cut is placed on the die, and the punch on the first punching die set is driven toward the die by the force arm to punch the pole piece.
[0052] In some embodiments, the male mold 24 and the female mold 25 are detachably connected to the template. In this way, when the male mold and the female mold are worn, or when it is necessary to cut pole pieces of other specifications, it is convenient to replace the male mold and the female mold on the punching and cutting die set, so that a set of tools can meet the cutting requirements of pole pieces of different specifications.
[0053] In some embodiments, the male mold 24 and the female mold 25 are set on the template 23 to be connected in a sliding fit, so that the male mold and the female mold can move in the punching direction, and a buffer 27 is set between the male mold and the template, and between the female mold and the template; the buffer is used to provide a certain buffering force or buffering space when cutting the pole piece, so that the punching force can be gradually applied to the pole piece, avoiding excessive impact on the pole piece during the cutting operation, resulting in material falling off at the edge of the pole piece. The buffer here can usually be a spring or other similar functional parts.
[0054] In some embodiments, a storage assembly 40 for storing the electrode pieces is provided below the punching hole on the second punching module 22. The interior of the storage assembly is connected to the punching hole and is used to store the electrode pieces that fall after punching to avoid damage to the electrode pieces after punching. The storage assembly can adopt a drawer-like structure to facilitate the removal of the electrode pieces.
[0055] In some embodiments, one end of the lever arm connected to the punching module is configured as a frame structure, which can increase the structural strength of the lever arm on the one hand, and increase the stability of the connection between the lever arm and the punching module on the other hand.
[0056] In some embodiments, a reset member may be provided to move the two punching dies away from each other after the punching operation is completed, so as to separate the two punching dies and further facilitate the cutting operation of the electrode sheet. The reset member may be a torsion spring provided between the two force arms, or a spring provided between the two punching dies, or other similar structures.
