Detailed Description
The following detailed description of embodiments of the utility model is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the utility model is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.
As shown in fig. 1 to 5, a tooling for detecting a laminated tile battery piece according to an embodiment of the utility model includes a first probe holder 1, a plurality of test probes 3 are integrally formed below the first probe holder 1, a second probe holder 2 is slidably connected to the first probe holder 1, and a support probe 4 opposite to the test probes 3 is screwed below the second probe holder 2.
The front surface of the laminated tile battery piece 5 is provided with a positive electrode 51, the back surface of the laminated tile battery piece 5 is provided with a back electrode 52 and a back electric field 53, and when the laminated tile battery piece 5 is tested, the test probe 3 positioned on the laminated tile battery piece 5 is contacted with the positive electrode 51, and the test probe 3 positioned under the laminated tile battery piece 5 is contacted with the back electrode 52. The supporting probe 4 corresponds to the testing probe 3, so that the pressure of the testing probe 3 to the laminated tile battery piece 5 can be counteracted, and the laminated tile battery piece 5 is prevented from being damaged due to the fact that shearing force is generated to the laminated tile battery piece 5.
The height of the supporting probe 4 is higher than that of the test probe 3, the supporting probe 4 comprises a first supporting probe 41 and a second supporting probe 42, a limiting hole 43 is formed in the first supporting probe 41, and a spring 44 is welded between the second supporting probe 42 and the bottom wall of the limiting hole 43.
Specifically, the output end of the moving mechanism is clamped on the probe frame, and the up-and-down movement of the probe frame can be controlled through the moving mechanism. When the test is required to be performed on the stacked battery piece 5, the test probe 3 and the support probe 4 on the probe rack are controlled to move towards the stacked battery piece 5 through the moving mechanism. Since the height of the supporting probe 4 is higher than that of the test probe 3, the second supporting probe 42 is firstly contacted with the laminated tile battery piece 5, and the impact force on the laminated tile battery piece 5 can be relieved through the spring 44, so that damage to the laminated tile battery piece 5 is avoided.
Along with the continued movement of the probe frame, the second supporting probe 42 contracts towards the limiting hole 43, namely, the testing probe 3 can be completely contacted with the positive electrode 51 and the back electrode 52, so that the current generated by the shingle cell 5 during testing can be completely led out through the back electrode 52 and the positive electrode 51, and more accurate testing data can be obtained.
The end of the second support probe 42 remote from the second probe holder 2 is bonded with a buffer pad 45. The cushion 45 is a non-conductive rubber pad, and the impact of the second support probe 42 on the shingled cell 5 can be further reduced by the cushion 45. While the support probe 4 can be further insulated from the back electric field 53 by the cushion pad 45. That is, the current generated on the back surface of the laminated cell 5 cannot be led out by the support probe 4 after being converged by the back electric field 53, so that the accuracy of testing the laminated cell 5 is improved.
It is conceivable that shear forces may still be generated to the shingled cells 5 due to the support probes 4 first coming into contact with the shingled cells 5, i.e., the support probes 4 above and below the shingled cells 5 are staggered at this time. No shear force is generated until the test probes 3 are in contact with the shingled cells 5 and the test probes 3 correspond to the support probes 4. However, the spring 44 greatly reduces the shearing force to the laminated cell 5 due to the buffering of the second supporting probe 42, that is, the spring does not cause the laminated cell 5 to be broken.
The support probe 4 is firstly contacted with the laminated tile battery piece 5, and can also play a role in fixing the laminated tile battery piece 5, so that the laminated tile battery piece 5 is prevented from shaking, and the test probe 3 cannot be accurately contacted with the positive electrode 51 and the back electrode 52.
The second support probe 42 is provided with an indication portion 46. The second probe holder 2 is provided with a fixing groove 22, an internal thread is arranged in the fixing groove 22, and an external thread is arranged at the upper end of the first supporting probe 41. Specifically, the spring 44 can be threaded into the fixed slot 22 to facilitate replacement of the support probe 4. The indicator 46 is a different color than the second support probe 42.
In the initial state of supporting the probe 4, the indication portion 46 is attached to the lower end surface of the spring 44. When the elastic force of the spring 44 decreases, the distance between the indication portion 46 and the first support probe 41 increases, facilitating observation. I.e. the situation of the spring force of the spring 44 is easily observed by the indicator 46. When the elastic force of the spring 44 decreases, the spring 44 can no longer effectively support the second support probe 42, i.e. the support probe 4 no longer has a supporting and fixing effect on the shingled cell 5.
The first probe frame 1 is welded with a plurality of slide rails 12, and the second probe frame 2 is provided with slide grooves 23 matched with the slide rails 12. The first probe frame 1 is provided with a threaded hole 13, and a fixing bolt 14 is connected in the threaded hole 13 in a threaded manner. The fixing bolt 14 can abut against the second probe holder 2, and further fix the second probe holder 2 to the first probe holder 1.
Specifically, as shown in fig. 4 and 5, when the stacked-tile battery cells 5 of different specifications are tested, the distance between the positive electrode 51 and the back electrode 52 may increase. The second probe holder 2 is adapted to different specifications of the shingled battery cells 5 by sliding on the sliding rail 12, i.e. adjusting the distance between the supporting probe 4 and the testing probe 3.
The first probe frame 1 is provided with a measuring line 11, the initial end of the measuring line 11 is aligned with the central axis of the test probe 3, the middle position of the second probe frame 2 is provided with an indicating line 21, and the indicating line 21 is aligned with the central axis of the support probe 4.
Specifically, the distance between the support probes 4 and the test probes 3 is conveniently and accurately adjusted through the measuring lines 11 and the indicating lines 21, so that the test probes 3 and the support probes 4 which are positioned above and below the laminated tile battery piece 5 are in one-to-one correspondence and are oppositely arranged, and the occurrence of dislocation to the laminated tile battery piece 5 is avoided. Meanwhile, the second probe holder 2 can also be completely slid out from the slide rail 12, namely, the second probe holder 2 is separated from the first probe holder 1, and the first probe holder 1 and the second probe holder 2 can be used as separate supporting probes and test probes at the moment.
In use, referring to fig. 1-5, when the shingled cell 5 is tested, the second support probe 42 will first contact the shingled cell 5, and as the support probe 4 moves toward the shingled cell 5, the second support probe 42 gradually contracts into the limiting aperture 43. The impact of the second support probe 42 on the stacked-tile battery cell 5 can be relieved by the spring 44, and the second support probe 42 can support and fix the stacked-tile battery cell 5 until the test probe 3 is completely in contact with the positive electrode 51 and the back electrode 52.
Compared with the prior art, the tooling for detecting the laminated tile battery piece can slow down the impact of the supporting probe on the laminated tile battery piece, is not easy to damage the laminated tile battery piece, and meanwhile, the supporting probe is higher than the testing probe in height, so that the testing probe can be fully contacted with the electrode on the laminated tile battery piece, and the testing result is not easy to influence.
