Description

Technical Field

[0001] The utility model relates to the technical field of battery cell testing, and in particular to a square battery cell testing device. Background Art

[0002] After the square battery cells are processed on the production line, it is necessary to scan and identify the QR code marked on the square battery cells to confirm that the model of the square battery cells is correct, and then use a multimeter to measure the contact between the positive and negative electrodes of the square battery cells to measure the internal resistance, voltage and other parameters of the square battery cells. The current testing equipment cannot simultaneously measure the positive and negative electrodes and scan and identify the QR codes of square battery cells of different volumes, which leads to low production efficiency. At the same time, the measurement of the positive and negative electrodes requires the multimeter's test leads to make contact, which is cumbersome to operate. In addition, during the test operation process, the square battery cells need to be manually held to ensure that the square battery cells do not shift, which also makes it inconvenient for the staff to operate.

[0022] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0023] Reference Figure 1A square battery cell testing device 1 comprises: a slide bar group 10, a testing mechanism 20 and a fixing assembly 30, wherein the fixing assembly 30 comprises two fixing plates 31; the slide bar group 10 comprises at least two slide bars 11 which are parallel to each other and arranged along the height direction of the fixing plates 31, wherein one fixing plate 31 is simultaneously penetrated through one end of the at least two slide bars 11, and the other fixing plate 31 is simultaneously penetrated through the other end of the at least two slide bars 11, and at least one of the two fixing plates 31 is simultaneously slidably connected with the at least two slide bars 11, wherein the penetration of a single slide bar 11 through the fixing plate 31 will cause the fixing plate 31 to flip, and thus the penetration of at least two slide bars through the fixing plate 11 can prevent the fixing plate from flipping.

[0024] The testing mechanism 20 includes a testing pen group 21 and a code scanning component 22. The testing pen group 21 is slidably arranged on at least two sliding rods 11, wherein the testing pen group 21 includes a plurality of testing pens 211, each testing pen 211 includes a pen body 2111 and a testing needle 2112, and a hollow placing portion 2111B is also provided on the pen body 211, one end of the testing needle 2112 is arranged in the placing portion 2111B, and the other end is arranged at the bottom of the pen body 211. In the present embodiment, there are two testing pens 211.

[0025] Among them, the test of the square battery cell 70 requires the use of the test leads of a multimeter to contact the positive and negative electrodes of the square battery cell 70 for testing. When the test leads of the multimeter are used to contact the square battery cell 70 for testing, the connecting wires of the test leads will be entangled with the square battery cell 70, resulting in inconvenience in the test operation. Therefore, a hollow placement portion 2111B is provided on the pen body 21, so that one end of the test needle 2112 can be set in the placement portion 2111B, and the multimeter can be directly connected to the test needle 2112 through the connecting wire to prevent the connecting wires of the multimeter test leads from being too long and entangled with the square battery cell 70 to affect the measurement operation.

[0026] The code scanning component 22 is slidably connected to one of the slide bars 11, and can rotate on the slide bar 11. The code scanning component 22 includes a rotating member 221 and a scanning terminal 222. The scanning terminal 222 is fixed to the rotating member 221. The rotating member 221 is slidably connected to one of the slide bars 11, and can rotate on the slide bar 11. A ring 2111A is provided on the top of the pen body 211, and the ring 2111A is inserted on the top slide bar 11. At least two connecting holes 2111C are provided on the pen body 2111, and a slide bar 11 is inserted in each connecting hole 2111C. The code scanning component 22 can rotate on the slide bar 11 to facilitate scanning of two-dimensional codes at different positions on the square battery cell 50.

[0027] In one embodiment, the slide bar group 10 includes three slide bars 11, which are parallel to each other and arranged along the height direction of the fixed plate 31, and at least one of the two fixed plates 31 is slidably connected to the three slide bars 11 at the same time; the test pen group is slidably inserted into the three slide bars 11, and the code scanning component 22 is rotatably connected to any one of the three slide bars 11.

[0028] In this embodiment, if Figure 1 and Figure 2 As shown, one fixing plate 31 is slidably connected to the three slide bars 11 at the same time, and the other fixing plate 31 is fixedly connected to the three slide bars 11. When using the fixing plates 31 to clamp the battery cells, it is only necessary to slide one of the fixing plates 31 until it is just matched with the other fixing plate 31 to clamp the battery cells, and then the fixing plate 31 is locked and fixed on the slide bars 11 by inserting the nut 12 into the slide bars 11. Preferably, one of the fixing plates is fixedly connected to the slide bars 11, and the other fixing plate 31 can be moved, thereby simplifying the operation steps of fixing the square battery cells 70.

[0029] It should be noted that the positions of the positive and negative poles of square battery cells 70 of different volumes are different. When performing measurements, one of the fixing plates 31 is adjusted to a position with the same volume as the square battery cell 70, and it cooperates with the other fixing plate 31 to clamp the square battery cell 70. When the two fixing plates 31 can just clamp the square battery cell 70, the fixing plate 31 is fixed using the nut 12. After the square battery cell 70 is fixed, the positions of the test pen 21 and the code scanning component 22 are adjusted, and they are moved to the positive and negative poles of the square battery cell 70 for measurement and to the QR code for scanning. The positive and negative pole measurements and the scanning of the QR code can be performed simultaneously, thereby simplifying the work process and improving work efficiency.

[0030] like Figure 2 As shown, in one embodiment, a first fixing hole 40 is provided on the collar 2111A, and the hole position is directly opposite to the slide rod 11 which is inserted into the collar 2111A.

[0031] It should be noted that when measuring the positive and negative electrodes of the square battery cell 70, the test pen 21 needs to be moved to the positive and negative electrode positions of the square battery cell 70. When using the test pen 211 for testing operations, the staff will inevitably touch the test pen 211 by mistake to prevent the test pen 211 from being separated from the positive and negative electrode positions of the square battery cell 50, resulting in the inability to perform the test. Therefore, a first fixing hole 40 is set on the ring 2111A so that it is just opposite to the sliding rod 11 passing through the ring 2111A. During the test operation, the ring 2111A is fixed by a pin through the fixing hole 40 to prevent it from sliding, thereby preventing the test pen 211 from moving.

[0032] In one embodiment, at least one second fixing hole 50 is provided on the pen body 2111, and the hole position is directly opposite to the slide bar 11 that is sleeved on the pen body 2111. In this embodiment, the pen body 2111 is provided with a second fixing hole 50, wherein the second fixing hole 50 on the pen body 2111 and the first fixing hole 40 on the sleeve 2111A have the same structure and use principle, which will not be repeated here.

[0033] like Figure 1 As shown, in another embodiment, a third fixing hole 60 is provided on the rotating member 221, and its hole position is directly opposite to the slide bar 11 that is sleeved on the code scanning component 22. Among them, the third fixing hole 60 on the rotating member 221 and the first fixing hole 40 on the collar 2111A have the same structure and use principle, which will not be repeated here.

[0034] Preferably, the connecting surface between the rotating member 221 and the scanning terminal 222 is a non-vertical surface with an inclined angle, and the inclination direction of the connecting surface is inclined from the top of the scanning terminal 222 to the direction away from the sliding rod, wherein the connecting surface between the rotating member 221 and the scanning terminal 222 is set as an inclined surface, and the inclination angle is not restricted. Therefore, when scanning the square battery cell 70, it is not necessary to rotate too large an angle, which facilitates the scanning operation of the QR code on the square battery cell 70.

[0035] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
