Abstract
Description
Technical Field
[0001] This utility model belongs to the field of new energy battery testing technology, specifically relating to a battery electrode tensioning device. Background Technology
[0002] In the new energy battery electrode packaging industry, push-pull force testing is an important step in evaluating the welding quality of battery electrodes. Currently, when using push-pull force testing equipment to test battery electrodes, clamping devices are mainly used to fix the battery electrodes.
[0003] Existing battery electrode clamping devices mostly use two clamping plates on both sides of the battery electrode. By manually rotating the bolt, one clamping plate is moved. After placing one end of the battery electrode between the two clamping plates, the bolt is reversed, and the two clamping plates move relative to each other to clamp the battery electrode. The other end of the battery electrode is clamped in the same way. This clamping device is too cumbersome to operate.
[0004] Therefore, a battery electrode tensioning device is designed to solve the technical problem of cumbersome operation when clamping and fixing battery electrodes in the existing technology.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0026] Research has found that existing battery electrode clamping devices mostly use two clamping plates on both sides of the battery electrode. By manually rotating a bolt, one clamping plate is moved. After placing one end of the battery electrode between the two clamping plates, the bolt is reversed, and the two clamping plates move relative to each other to clamp the battery electrode. The other end of the battery electrode is clamped in the same way. This clamping device is too cumbersome to operate.
[0027] Based on the above research, this disclosure provides a battery electrode tensioning device. By providing a clamping seat and two clamping members inside the clamping seat, when performing a tensile test on the battery electrode, the operator only needs to manually rotate the handle to push the two clamping members to clamp the end of the battery electrode. Compared with the prior art, which manually rotates the screw to control the clamping blocks to move up and down to clamp the end of the battery electrode, this is more convenient to operate.
[0028] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.
[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0030] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0031] In some embodiments, such as Figure 1 As shown, when the battery electrode 4 is tensioned, the operator inserts both ends of the battery electrode 4 vertically into the battery electrode placement positions 300 opened on the two clamping seats 30, manually rotates the drive handle 32 on the two clamping seats 30, and uses the drive handle 32 to push the two clamping members 31 in each clamping seat 30 to clamp the ends of the battery electrode 4. Then the driver 1 is started, and its output end drives the lead screw 10 to rotate. Since the lead screw 10 is threadedly connected to the moving plate 20, and the guide rod 11 passes through the moving plate 20 and is slidably connected to the moving plate 20, at this time, as the lead screw 10 rotates, the moving plate 20 is driven to move away from the fixed plate 21 along the axis of the guide rod 11, thereby realizing the tensioning of the battery electrode 4.
[0032] In some embodiments, such as Figure 2 and Figure 3As shown, after one end of the battery electrode 4 is inserted into the corresponding battery electrode placement position 300, the operator turns the drive handle 32, which drives the connected sector gear 320 to rotate around the bearing connection between the sector gear 320 and the clamping seat 30. At this time, the sector gear 320 meshes with the gear teeth provided on the sliding part 312a of the push bar 312 below it. When the sector gear 320 rotates, it drives the sliding part 312a to move in the sliding cavity 301. The push part 312b is located in the push position 310 opened on the two clamping members 31. As the sliding part moves, the sliding part moves in the direction of rotation. The movement of 312a causes the pushing part 312b to push the two clamping parts 31 to slide within the battery electrode placement position 300. The battery electrode placement position 300 is conical. The two clamping parts 31 slide along the inclined surface of the battery electrode placement position 300 to close to the corresponding ends of the battery electrode 4. There is a certain damping between the sliding part 312a and the sliding cavity 301 to prevent the drive handle 32 from deflecting randomly after losing manual driving. Compared with the prior art, which uses manual rotation of the screw to drive the clamping parts to move up and down to clamp the battery electrode, this operation is simpler and more convenient.
[0033] In the description of the embodiments of this utility model, 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 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; 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 this utility model based on the specific circumstances.
[0034] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0035] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0036] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0037] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
