Description

Technical Field

[0001] This utility model relates to the field of resistance detection technology, specifically to a contact-type automated continuous resistance detection device. Background Technology

[0002] By detecting the resistance value, potential manufacturing defects can be identified and eliminated, thereby ensuring the safety and reliability of the battery and ensuring that the battery module does not have problems such as short circuits or poor connections when it leaves the factory.

[0003] In traditional battery module resistance testing methods, each individual battery module typically needs to be tested one by one. The number of start-stop cycles of the conveyor mechanism used to transport the battery modules is the same as the number of battery modules. As a result, the conveyor mechanism needs to pause and start frequently. Each start and pause consumes a certain amount of time. Frequent operation will significantly slow down the overall testing speed, thereby reducing the overall testing efficiency and increasing the failure rate of the conveyor mechanism.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This invention proposes an automated continuous contact resistance testing device capable of continuously testing the resistance of multiple battery modules 3. The basic structure of the testing device includes a conveyor frame 1, a support structure 2 on the conveyor frame 1, four battery modules 3 arranged in a grid pattern fitted onto the top of the support structure 2, a testing component 4 above the conveyor frame 1, and adjustment components 5 on both sides of the conveyor frame 1 to move the testing component 4 along three-dimensional space above the battery modules 3. In practical application, the battery modules 3 are secured to the top surface of the support structure 2, and then the conveyor frame 1 is operated to transport the support structure 2 from back to front to a specific position. The specific structure and operating principle of the conveyor frame 1 are basically the same as in existing technologies, and therefore will not be described in detail here. Then, in conjunction with the operation of the adjustment components 5, the testing component 4 is moved sequentially onto the four battery modules 3 according to a set program for resistance testing.

[0027] Specifically, the adjustment component 5 includes support frames located on both sides of the conveyor frame 1. A Y-axis electric guide rail 501 is mounted on the support frames. A lifting platform 502 is slidably sleeved on the Y-axis electric guide rail 501. An X-axis electric guide rail 503 is located at the top of the lifting platform 502. A Z-axis electric guide rail 504 is slidably sleeved on the X-axis electric guide rail 503. Sliding blocks 505 for connecting the detection component 4 are slidably sleeved on both sides of the Z-axis electric guide rail 504. During the operation of the adjustment component 5, the Y-axis electric guide rail 501 drives the various structures above it to move along the front-back axis. The X-axis electric guide rail 503 can drive the Z-axis electric guide rail 504, the sliding blocks 505, and the detection component 4 to move along the left-right axis. In conjunction with the Z-axis electric guide rail 504, the sliding blocks 505 and the detection component 4 can be controlled to move along the up-down axis. The combined application of these three components, along with the support structure 2 being moved forward by the conveyor frame 1 to the set position and the certainty of the placement of the battery module 3 on the support structure 2, enables precise control of the position of the detection component 4, ensuring accurate contact between it and each battery module 3. Furthermore, through three-dimensional displacement, the detection component 4 can adjust its position according to specific circumstances, adapting to battery modules 3 of different sizes and arrangements. This enhances the flexibility and adaptability for continuous testing of multiple battery modules 3, while simplifying the operation process and improving testing efficiency.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, the top of the battery module 3 has two conductive parts 301 arranged side by side, and a QR code bar 302 located between the two conductive parts 301. The detection component 4 includes an extension plate 401 fixedly installed on the front of the slider 505. Two hanging plates 402 are arranged side by side at the bottom of the extension plate 401, and a detection needle 403 is installed at the bottom of the hanging plate 402. A scanner is located in the middle of the bottom surface of the extension plate 401. By scanning the QR code bar 302 with the scanner, information such as the preset resistance voltage of the battery module 3 can be obtained. Then, by using the detection needle 403 to contact the two positive and negative conductive parts 301, the actual resistance voltage information of the battery module 3 can be detected. Through a processor electrically connected to the detection component 4, the detected resistance voltage can be compared with the preset resistance voltage, thus quickly determining whether the battery module 3 is qualified.

[0029] Normally, battery modules 3 come in multiple sizes, so the spacing between the two conductive parts 301 on the upper side will vary depending on the size of the battery module 3. To address this, and to improve the adaptability of the detection component 4 to various battery module sizes, such as... Figures 2-4As shown, the top of the extension plate 401 has two parallel through slots 4011. A column structure 404, extending upwards through the through slots 4011, is mounted on the hanging plate 402. Two limiting blocks 405 are mounted on the extension plate 401, and a bidirectional lead screw 406, with its end passing through the column structure 404, is inserted between the two limiting blocks 405. When the above structures are used in conjunction, rotating the bidirectional lead screw 406 controls the two column structures 404 to move along the two through slots 4011 in opposite or opposite directions, thereby adjusting the distance between them. Ultimately, this achieves the purpose of adjusting the distance between the two detection pins 403 based on the distance between the two conductive parts 301 on the battery module 3, effectively improving its adaptability to various models of battery modules 3.

[0030] Following the above, the column structure 404 includes a sliding column 4041 with a diameter consistent with the inner width of the front and rear of the through groove 4011. A limiting column 4042 with a diameter larger than that of the sliding column 4041 is installed on the top of the sliding column 4041. A groove 4043 is formed on the surface of the limiting column 4042. A fitting slide plate 4044 extending into the groove 4043 is fitted on the surface of the bidirectional lead screw 406. The height of the fitting slide plate 4044 is less than the inner height of the groove 4043. The bottom of the limiting block 405 passes through the extension plate 401. A gear column 4061 is fixedly fitted in the middle of the bidirectional lead screw 406. The top surface of the extension plate 401 is provided with a toothed groove 4012 that matches the bottom of the gear column 4061. Based on the above structural application, before rotating the bidirectional lead screw 406, an upward lifting force needs to be applied to it, causing the bottom of the gear column 4061 to disengage from the tooth groove 4012. Simultaneously, the limiting block 405 rises upward, and the engaging slide plate 4044 moves upward along the slide groove 4043. At this point, rotating the gear column 4061 drives the bidirectional lead screw 406 to rotate, effectively achieving the lateral movement of the column structure 404. Furthermore, after the distance between the two detection pins 403 is adjusted, removing the lifting force on the bidirectional lead screw 406 allows the gear column 4061 to fall back to its bottom position where the tooth tips are engaged within the tooth groove 4012. This effectively prevents the bidirectional lead screw 406 from rotating arbitrarily, thus effectively maintaining the stability of the distance between the two detection pins 403.
