Before the technical solutions of the present application are introduced, it is necessary to explain the background of the invention of the present application.
It has been common in the related art that the cell 200 leveling and short circuit tests are separate stations. After the vibration leveling, the battery cell is placed on the short-circuit tester 110 for a short-circuit test, and in the process, there are two actions of picking and placing the material, that is, after the short-circuit test is performed, the battery cell 200 to be tested is removed from the test station, and then the battery cell 200 to be tested is placed on the short-circuit test station. This obviously increases the number of steps required for testing, which is time consuming and inefficient.
Based on the above-mentioned problems that the inventor is aware of, the inventor proposes that when performing the vibration leveling and short circuit test on the battery cell 200, the battery cell 200 to be tested is first placed on the carrier 130, and then the driving cylinder 120 is operated and started, and the driving cylinder 120 drives the vibration leveling test platform 150 to move, when the vibration leveling test platform 150 is driven to contact the two electrode conductive parts of the battery cell 200 to be tested, the probes 160 will contact the electrode conductive parts, which are the short circuit test station and the vibration leveling test station, at this time, the short circuit test and the vibration leveling test can be performed at the same time, thereby avoiding the problem that the operation efficiency is slow due to the need to readjust the placement position of the battery cell 200 to be tested to perform the short circuit test after the vibration leveling test in the related art, and effectively improving the test efficiency. Therefore, the invention is created.
Referring to fig. 1 and fig. 2, the present application provides a device for testing a vibration-leveling short circuit of a battery cell 200, including:
a carrier 130 for placing the electrical core 200 to be tested;
a second vibration leveling test platform 150 for performing vibration leveling by contacting conductive portions of the two electrodes of the electrical core 200 to be tested;
a driving cylinder 120, the power output rod of which is fixedly connected with at least one vibration platform so as to separate or attach the vibration platform to at least one electrode conductive part;
two probes 160 electrically connected to the short circuit tester 110, the probes 160 are used to fix the vibration-leveling testing platform 150.
It should be understood that, the probe 160 is fixedly connected to the vibration-leveling testing platform 150, so that the probe 160 can be ensured to synchronously contact the electrode conductive part when the vibration-leveling testing platform 150 contacts the electrode conductive part of the electrical core 200 to be tested, thereby facilitating the simultaneous implementation of the vibration-leveling test and the short-circuit test.
In view of the fact that the short circuit test and the vibration leveling test of the battery cell 200 have been widely applied to the conventional test of the battery cell 200, the test equipment adopted for the short circuit test and the vibration leveling test is known by those skilled in the art, and will not be described again. The vibration table described above in this application may take any form of vibration level testing known to those skilled in the art, and the short circuit tester 110 may take any form of vibration level testing known to those skilled in the art.
As an exemplary implementation of the location of the probe 160 on the vibration-leveling testing table 150, the probe 160 is convexly disposed on the central portion of the vibration-leveling testing table 150 far from the surface of the driving cylinder 120.
Therefore, through the setting of the central position, it is possible to make, as long as the central hole position of the electrical core 200 to be tested is aligned with the central position of the vibration-leveling test platform 150, when the vibration-leveling test platform 150 is driven to the conductive position of the two end electrodes clamping the electrical core 200 to be tested, the fixing force applied by the vibration-leveling test platform 150 to the electrical core 200 to be tested is just located in the central hole of the electrical core 200 to be tested, thereby avoiding the moment change of the electrical core 200 to be tested caused by the fixing force applied by the vibration-leveling test platform 150 to the electrical core 200 to be tested and the turning, which not only causes the fixing of the electrical core 200 to be tested to be damaged, but also causes the deterioration of the effect of the vibration-leveling test platform 150 to the electrical core 200, thereby affecting the accuracy of the vibration-leveling test result. Because the probe 160 is located at the central position of the vibration-leveling testing platform 150, when the vibration-leveling testing platform 150 contacts the conductive part of the two end electrodes of the electrical core 200 to be tested, the probe 160 can be just positioned in the central hole of the electrical core 200 to be tested, so as to obtain a better positioning effect, and avoid the inaccurate short-circuit test result caused by the loose contact of the probe 160 with the conductive part.
In the embodiment where the probe 160 is located at the center of the vibration-leveling testing table 150, the probe 160 is protruded from the surface of the vibration-leveling testing table 150 by a compression spring (not shown).
Therefore, through the arrangement of the compression spring, the compression spring can generate compression elastic force for the vibration flat test table 150, and the positioning firmness of the probe 160 and the center hole of the battery cell 200 to be tested is enhanced. In addition, the compression spring can also buffer the feeding stroke of the probe 160 relative to the battery cell 200 to be tested, so as to avoid the probe 160 from being excessively damaged when the probe 160 is fed along with the vibration-leveling test platform 150.
With respect to the probe 160, in the foregoing functional description of the probe 160, it has been implicitly indicated that the probe 160 is made of a conductive metal. In order to improve the positioning effect between the probe 160 and the battery cell 200 to be tested, a sharp portion may be disposed at an end of the probe 160, so as to facilitate the insertion positioning effect of the probe 160 in the center of gravity hole of the battery cell 200 to be tested.
The phrase "at least one of the driving cylinder 120 makes the vibration platform separate from or attach to at least one of the electrode conductive parts" indicates that the driving cylinder 120 drives the motion of one vibration platform or drives the motion of two vibration platforms.
In order to drive the shake-flat test stand 150 more quickly, the number of the driving cylinders 120 is two as shown in fig. 1, and the two shake-flat test stands 150 are fixedly connected.
It is contemplated that a chute may be provided to support the telescoping action of the driven cylinders 120 of the shake-out test station 150.
As an example of a similar structure, a guide plate 141 is fixed to the power output rod of the driving cylinder 120, the guide plate 141 is fixed to the vibration level testing table 150, and the guide plate 141 slidably penetrates through the guide post 142.
Therefore, the cooperation of the guide post 142 and the guide plate 141 can ensure that the driving force output by the driving cylinder 120 to the vibration-leveling test platform 150 is maintained in a linear reciprocating motion, so as to avoid the driving stroke from being not straight enough to cause the inclination of the positioning of the electric core 200 to be tested (i.e. the positioning of the vibration-leveling test platform 150 and the probe 160 and the electrode conductive part of the electric core 200 to be tested is not firm), and the positioning effect of the vibration-leveling test platform 150 and the probe 160 and the electrode conductive part of the electric core 200 to be tested is damaged.
As an exemplary implementation manner of the specific structure of the carrier 130, the carrier 130 includes a carrier block and a placement groove formed in the carrier block.
Here, the carrier block may be a square block, but may be in any form such as a frame.
The placing groove is beneficial to positioning the battery cell 200 to be tested.
The opening of the placing groove is made of elastic materials. Thus, the battery cell 200 to be tested is prevented from loosening in the placement groove.
In addition to the implementation of the resilient material of the opening of the placement groove here, as a similar alternative to the same effect, a resilient locking member or a bolted locking member is placed in the placement groove. Here, the elastic locker may be a telescopic spring. The bolt locks may be any bolts with fastening.
The operation of the correction of the present application will now be described with respect to a common application scenario. It should be noted that this common embodiment is not to be taken as an identification basis for understanding the essential features of the technical problem to be solved as claimed in the present application, which is merely exemplary.
Again, referring to fig. 1 and 2, the specific flow of the test is as follows:
the cell 200 to be tested is taken out and placed in the carrier of the cell 200, the central cylinder of the vibrating block is aligned with the central hole of the cell 200, the switch is pressed (started) by both hands, and the driving cylinders 120 on both sides of the vibrating test platform 150 push the cell 200 to be tested. When the driving cylinder 120 stops holding after pushing to the set length, and the driving cylinder 120 goes to the set position, a signal for starting short circuit test is given to the short circuit tester 110, and the short circuit test is finished after about 4S. Then, after the short circuit tester 110 performs the discharging operation of the battery cell 200, the two ends of the vibration-leveling test platform drive the cylinders 120 to return to the original position after about 2S. If the test is not qualified, the instrument alarms; and if the test is qualified, the lamp is turned on. And finally, taking out the battery cell 200 and carrying out the next operation. And classifying and placing the qualified and unqualified battery cores 200.
The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application.
