The battery tab clamping device according to the embodiment of the present application includes: a clamp 10 for releasably clamping a battery tab; and a support 11 supporting the jig; wherein: the clamp is rotatably mounted to the support.

The clamp 10 is used to releasably clamp a battery tab to facilitate electrical connection of the tab to other electrical devices. The support 11 is intended to support the clamp in a height position convenient for handling.

Compared with the conventional tab clamping device, the technical scheme of the application is characterized in that the rotatable connection relationship between the support 11 and the clamp 10 is realized. Therefore, according to different working conditions, the tab to be clamped can be allowed to approach the clamp 10 in different directions and be clamped by the clamp 10.

The rotatable pair between the support 11 and the clamp 10 can be realized in various forms. For example, the two can be realized by a ball joint, or by a joint shaft. The axial direction of the hinge shaft can be selected according to specific working conditions, and preferably, the axial direction of the hinge shaft is a vertical direction. Thus, in the embodiment shown in fig. 2 and 3, the clamp 10 can be selectively rotated in a horizontal plane with respect to the support 11.

Preferably, the clamp 10 is provided with a releasable lock in front of the support 11. After the clamp 10 is adjusted to a certain orientation as required, the clamp 10 can be locked on the support 11 by using the locking member, so that the clamp 10 is prevented from moving and the clamping of the tab is prevented from being influenced. When it is desired to adjust the orientation of the clamp 10, the locking member may be released, allowing the clamp 10 to be rotated to the appropriate position relative to the support 11, and then locking the clamp 10. The locking member may take a variety of forms, such as a pin, a snap, etc.

The clip 10 may have a variety of configurations, for example, it may be a dovetail clip-like configuration. Preferably, as shown in fig. 2 and 3, the jig 10 includes: a frame 101, wherein the frame 101 comprises a bottom frame 1011 and a top frame 1012 fixedly connected with the bottom frame 1011 and arranged at a distance from each other, and the bottom frame 1011 is rotatably supported by the support 11; a movable chuck 102, wherein the movable chuck 102 is mounted on the top frame 1012 in a manner of moving up and down, and a first conductor 1021 is insulated from the bottom end of the movable chuck 102; a fixed chuck 103, the fixed chuck 103 is fixedly disposed on the top of the bottom frame 1011, and a second conductor 1031 is disposed on the top end of the fixed chuck 103 in an insulating manner, wherein: the movable clamp 102 has a clamping position for clamping the first conductor member 1021 and the second conductor member 1031, and a release position for separating the first conductor member 1021 and the second conductor member 1031.

The frame 101 constitutes a main body portion of the jig 10. The base frame 1011 is rotatably supported by the support 11, thereby enabling the jig as a whole to have a degree of freedom of rotation with respect to the support 11. The top frame 1012 and the bottom frame 1011 are spaced apart from each other so that the moving head 102, which is movable through the top frame 1012, can approach or move away from the bottom frame 1011. The fixed jaw 103 is provided at the top of the bottom frame 1012 (i.e., a portion facing the top frame 1012) to be engaged with the moving jaw 102.

The bottom frame 1011 and the top frame 1012 may be fixedly attached to each other in a variety of ways, such as being integrally formed, or a single rod may be used to fixedly attach the bottom frame 1011 and the top frame 1012. Preferably, as shown in fig. 2 and 3, the frame 101 includes a pair of side frames 1013 and 1014 fixedly connected between the bottom frame 1011 and the top frame 1012 at a distance from each other. Accordingly, the frame 101 forms a relatively stable integral structure and forms a clamping space between the bottom frame, the top frame and the pair of side frames.

The moving jaw 102 preferably includes a moving rod 1022, the moving rod 1022 movably passing through the through-hole of the top frame 1012 to allow the moving jaw 102 to move relative to the top frame 1012. The moving bar 1022 is preferably releasably locked to the top frame 1012, such as by a locking pin or the like, to hold the moving bar 1022 in position relative to the top frame 1012 and thus the moving 102 and fixed 103 jaws in position relative to each other. As shown in fig. 2, it is preferable that a handle 1023 is provided at the tip of the moving bar 1022 for easy operation. When the clamping operation is performed by the clamp 10, the movable clamp 102 can be moved up and down by the handle 1023.

As shown in fig. 3, a first conductor 1021 is provided in an insulated manner at the bottom end of the movable chuck 102. For example, the moving jaw 102 may be made of an insulating material, such as plastic, except for the first conductor member 1021; or may be made of a metal material with insulation protection provided between the first conductor member 1021. Preferably, as shown in fig. 3, the first conductor 1021 is detachably mounted to the bottom end of the moving rod 1022 through a first insulating material. The first conductor 1021 may be a first conductor plate made of a conductor material, the first conductor plate having a first plate face facing the second conductor; and/or the first insulating material is formed as a first insulating plate 1024, and the first conductor plate is detachably mounted to the bottom end of the moving bar 1022 through the first insulating plate 1024. In the embodiments of the present application, the first conductor and the insulation manner thereof are not limited to the specific structural form shown in fig. 3, and may have other structural forms that can achieve the functional purpose thereof.

A second conductor 1031 is provided on the tip end of the fixed collet 103 in an insulated manner. Therefore, when the moving jaw 102 may be dropped to a clamping position where the first conductor member 1021 and the second conductor member 1031 are clamped to each other, so as to be able to clamp the tab between the first conductor member 1021 and the second conductor member 1031, facilitating electrical connection with other electrical devices. When the movable clamp 102 moves upward, the first conductor member 1021 and the second conductor member 1031 may be separated from each other, so that the tab may be released. The fixed clip 103 comprises a second insulating material (e.g., a plastic material), preferably formed as a second insulating plate 1032, through which the second conductor 1031 is detachably mounted to the top of the bottom frame 1011. Similarly, as shown in fig. 3, the second conductor 1031 is a second conductor plate made of a conductor material, and the second conductor plate has a second plate surface facing the first conductor.

Through the above description of the specific structure examples of the movable chuck and the fixed chuck, the first conductor piece and the second conductor piece respectively form the first plate surface and the second plate surface facing each other, so that the first plate surface and the second plate surface can respectively clamp the tab at both sides of the battery tab. Because the contact area of the first plate surface and the second plate surface with the pole lug is relatively large, the reliable clamping force can be realized for the pole lug, and good electric connection can be provided. In addition, through the detachable design of above-mentioned insulation board, can conveniently remove the change of chuck and fixed chuck.

Various structural features of the clamp 10 are described in detail above. In the above embodiment of the jig 10, as shown in fig. 3, preferably, the hinge shaft is a threaded fastener 12, and the threaded fastener 12 is screwed into the holder 11 through the bottom frame 1011. It is further preferred that the threaded fastener 12 releasably secures the fixed jaw 103 to the base frame 1011 together, thereby acting as a releasable lock. In this embodiment, when the threaded fastener 12 is tightened, the effect of the fixed connection of the clamp 10 to the support 11 is achieved. And when the threaded fastener 12 is loosened, the clamp 10 is allowed to rotate in a horizontal plane relative to the support 11 about the threaded fastener 12 to adjust the clamping direction of the clamp 10. Thus, the threaded fastener 12 can function as both a connection and a hinge.

The battery tab clamping device provided by the present application is described in detail above. How the battery tab clamping device is utilized is described below in connection with the battery performance testing system provided herein.

As shown in fig. 4 and 5, the battery performance test system according to the present application includes: an operation panel 100 having an operation surface 1001 and a runner 1002 recessed in the operation surface 1001; and at least two battery tab clamping devices, the battery tab clamping devices are the battery tab clamping devices, and the support 11 of each battery tab clamping device is arranged in the sliding groove 1002 in a sliding manner.

The operation panel 100 is used to provide a countertop for the battery performance testing system. For placing the battery tab holding device, a recessed runner 1002 is provided on the operating surface 1001 for receiving the seat 11 of the battery tab holding device. Therefore, the battery tab clamping device can slide back and forth in the sliding groove 1002 through the support 11, and when a plurality of battery tab clamping devices are arranged, the battery tab clamping devices can be moved according to different working conditions, such as batteries with different sizes, so that the battery tab clamping devices are matched with tab positions to be clamped.

The shape of the slide slot 1002 and the shape of the support 11 are matched to each other to facilitate the sliding of the support 11 in the slide slot 1002. For example, as shown in FIG. 4, the runner 1002 is preferably a T-shaped slot to prevent the holder from backing out. In the present application, the chute 1002 may have other cross-sectional shapes, such as a triangular shape.

When the performance of the battery is tested, the battery cell to be tested may be placed on the operation surface 101. Then, one tab is respectively fastened by using two battery tab clamping devices, and the two tabs are electrically connected to a pair of wiring terminals of the tester. Therefore, a connection circuit is established between the battery and the tester by the aid of the battery tab clamping device, so as to facilitate subsequent performance tests, such as charge and discharge performance tests.

As described above, a pair of tabs of the battery (single cell) to be tested may be disposed in the same side or opposite sides (as shown in fig. 1a and 1 b). The battery tab clamping device provided by the application can be universally used for two layout modes of tabs. For example, as shown in fig. 4 and 5, when the clamps of two battery tab holding devices are oppositely arranged, the opposite side layout of the tabs shown in fig. 1b can be applied. When the same-side layout is performed, the distance between the two battery tab clamping devices (corresponding to the distance between the two tabs) can be adjusted, and the two clamps are rotated by a proper angle (such as 90 degrees) relative to the respective supports, so that the two clamps are adjacently arranged and respectively correspond to the two tabs to clamp the tabs in the same-side layout. Therefore, when the battery tab clamping device faces the tabs with different layouts, the battery tab clamping device can perform conversion in a short time, and the universality and the flexibility are good. The battery monomer to be tested is preferably a soft package battery monomer.

Although only two battery tab holding devices are illustrated in the drawings of the present application, more battery tab holding devices may be designed, and a plurality of slide grooves may be designed in the operating plate 100. According to the arrangement, large-scale battery performance test work can be carried out on the operation board at the same time, and the working efficiency is improved to a great extent. This is also achieved thanks to the rotatable design between the clamp and the support.

The directional terms described in this application, such as "upper, lower, top, bottom", etc., are used in the orientations indicated in the drawings to exemplarily indicate relative positional relationships, and do not limit the scope of the present application. For example, although in the orientation shown in FIG. 2, the support 11 is below and the clamp 10 is above, in actual practice, the orientations may be reversed, and this is within the scope of the present application.

The preferred embodiments of the present application have been described in detail above, but the present application is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present application within the technical idea of the present application, and these simple modifications all belong to the protection scope of the present application.

It should be noted that, in the foregoing embodiments, various features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various possible combinations are not described in the present application.

In addition, any combination of the various embodiments of the present application can be made, and the same should be considered as the disclosure of the present invention as long as the combination does not depart from the spirit of the present application.
