The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
A first clamp and a second clamp are arranged separately from a support plate, and are flexibly placed on the support plate when in use, so that electrodes which are not on the same end face of a battery cell can be conveniently connected, and the application range is wide; the supporting plate end is connected with a fixing piece, and the fixing piece is provided with a limiting hole matched with the first clamp and the second clamp, so that the cable of the testing equipment is limited, and the phenomenon of bending of the battery cell caused by torsion of the cable can be effectively prevented.
The specific embodiment is as follows:
As an example of the present embodiment, the stopper hole 121 is provided in 7.
The clamp 2 and the support body 1 are arranged in a split mode, and the clamp is used for connecting an electrode of the battery cell 3 and a cable 4 of the testing equipment. The jig 2 includes a first jig 21 and a second jig 22. One end of the first clamp 21 is used for connecting the positive electrode 31 of the battery cell 3, and the other end is used for connecting a positive cable 41 of the testing equipment. One end of the second clamp is connected with the negative electrode 32 of the battery cell 3, and the other end of the second clamp is connected with a negative electrode cable 42 of the testing equipment. When testing the battery cell 3, the first clamp 21 and the second clamp 22 are placed on the support plate 11 after being connected with the battery cell 3, so that the flexibility is strong, and the connection of the battery cells 3 with electrodes not on the same end surface is facilitated.
In the present embodiment, the jig 2 is made of brass, which has good electrical conductivity.
In other embodiments, the difference from the above embodiments lies in the material of the clamp 2, the clamp 2 is made of aluminum or other materials with good conductivity, and other structures are not described herein again.
When the positioning assembly for testing the individual battery cells is used, the battery cell 3 is placed on the supporting plate 11, the first clamp 21 is used for clamping the positive electrode 31, the other end of the first clamp 21 is connected with the positive electrode cable 41 of the testing equipment, the second clamp 22 is used for clamping the negative electrode 32, and the other end of the second clamp 22 is connected with the negative electrode cable 42, so that the connection between the battery cell 3 and the testing equipment is realized. In order to avoid bending of the battery cell 3 caused by twisting and winding of the positive cable 41 and the negative cable 42, the positive cable 41 and the negative cable 42 are passed through the appropriate limiting hole 121, so that the distance between the positive cable 41 and the negative cable 42 is limited, the acting force on the battery cell 3 when the cable 4 is twisted is reduced, and the bending of the battery cell 3 is effectively prevented. Meanwhile, the first clamp 21 and the second clamp 22 are arranged separately from the support part 1, and when the battery pack is used, the first clamp 21 and the second clamp 22 are high in flexibility when being placed on the support plate 11, applicable to battery cells 3 with different distances between two electrodes, applicable to battery cells 3 of different types and sizes, applicable to battery cells 3 with electrodes on the same end face and different end faces, and applicable to a wider range of applications; the multipurpose device has the advantages that the occupied space is reduced, the testing environment is improved, the working efficiency of soft package single cell testing personnel is greatly improved, and the safety problem caused by external factors is reduced.
Further, the first clamp 21 includes a clamping portion and a connection plate 211. The clamping portion includes a clamping slot 212 and an adjustment clamp. The adjusting pressure plate is matched with the clamping groove 212 to clamp the anode 31.
As an example of the present embodiment, the clamping slot 212 is a horizontally-horizontal U-shaped slot structure. The adjusting pressure plate includes a pressure plate 213 and an adjusting bolt 214. The pressing plate 213 is located in the U-shaped slot and can move up and down. Adjusting bolts 214 are connected to the upper end of the pressing plate 213, and the adjusting bolts 214 penetrate through the wall of the U-shaped clamping groove at the top and are in threaded connection with the U-shaped clamping groove. The adjusting bolt 214 is rotated to adjust the up-and-down movement of the adjusting bolt 214, the adjusting bolt 214 drives the pressing plate 213 to move up and down in the U-shaped clamping groove, and when the adjusting bolt 214 drives the pressing plate 213 to move down to press the wall at the bottom of the U-shaped clamping groove, the pressing of the anode 31 placed between the pressing plate 213 and the wall at the bottom of the U-shaped clamping groove is realized.
As an example of this embodiment, the lower end of the adjusting bolt 214 is rotatably connected to the pressing plate 213, so that when the adjusting bolt 214 is rotated and the pressing plate 213 is tightly attached to the U-shaped slot, the pressing plate 213 does not rotate with the adjusting bolt any more, and the positive electrode 31 is prevented from being damaged due to the torsional force generated on the positive electrode 31.
The connection plate 211 is attached to the end of the clamping slot 212 remote from the opening. The connection plate 211 is provided with a connection hole for connecting the positive cable 41.
In other embodiments, the adjusting pressure plate is pressed by an elastic structure. For example, the adjusting pressure plate comprises a pressure plate and a spring, the spring is connected to the wall of the U-shaped clamping groove at the top, and the pressure plate is tightly attached to the wall of the bottom of the U-shaped clamping groove downwards under the action of the spring to press the anode; the adjusting pressure plate comprises a pressure plate and an elastic sheet, the elastic sheet is connected to the wall, located at the top, of the U-shaped clamping groove, the elastic sheet is located in a bending state, the pressure plate is tightly attached to the wall, located at the bottom of the U-shaped clamping groove, downwards under the action of the elastic sheet, and the pressing of the positive electrode is achieved. Other structures are not described in detail herein.
Further, the structure of the second jig 22 is identical to that of the first jig 21. And the second clamp 22 connects the negative pole 32 and the negative pole cable 42 in the same manner as the first clamp 21. First anchor clamps 21 and second anchor clamps 22 are simple with the connected mode of electrode, and convenient operation need not to punch to the electrode, has avoided the damage because of punching the electrode leads to the fact, has promoted efficiency of software testing simultaneously.
Further, the support plate 11 is provided with heat dissipation holes 111. The plurality of heat dissipation holes 111 are uniformly distributed on the support plate 11. When testing electric core 3, electric core 3 is for generating heat, and louvre 111 helps electric core 3 to dispel the heat, has reduced the influence of temperature factor to electric core 3 test result, has promoted the degree of accuracy of test result.
Furthermore, the bottom of the supporting plate 11 is also provided with two cushion blocks 13, and the two cushion blocks 13 are strip-shaped and are respectively padded at the front end and the rear end of the supporting plate 11. The cushion block 13 isolates a gap between the support plate 11 and the table-board, so that the heat dissipation of the battery cell 3 is accelerated, and the heat dissipation effect is further improved.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without the technical solutions of the present invention, or the present invention can be directly applied to other occasions without the improvements, and all are within the protection scope of the present invention.
