Description

Technical Field

[0001] This utility model relates to the field of automatic testing of power batteries, specifically to a quick-assembly and disassembly floating battery test head and its testing device. Background Technology

[0002] A power battery is a power source that provides power to tools, primarily referring to the batteries that power electric vehicles, electric trains, electric bicycles, and golf carts. Power batteries are a core component of new energy vehicles and an important direction for future energy transition.

[0003] The manufacturing process of power batteries involves parameter testing. Power batteries include various types of external interfaces, which are located at the ends and top and bottom sides of the power battery. In the automated testing process of power batteries, test heads need to be designed as auxiliary tools to connect the power battery to the test circuit. For connector-type interfaces on the battery, multiple test probes need to be inserted into the connector to connect the battery to the test circuit. During the insertion of test probes, due to the small diameter of the strip-shaped test probes and the need to insert multiple probes at the same time, the test probes are very prone to bending deformation or breakage due to positional deviation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a battery floating test head and its testing device that uses a protective outer jacket structure for the test head to effectively protect the test probe and has a flexible pre-compression function to achieve local pre-compression and leveling of the battery surface before testing, thereby effectively improving the insertion position accuracy, insertion success rate and efficiency.

[0005] The technical solution adopted in this utility model is as follows: A quick-assembly and disassembly floating battery test head for battery testing includes an upper test support, an upper test cylinder, an upper test slide, an upper test support plate, and test pieces. The upper test support is mounted on a support plate above the battery to be tested. The upper test cylinder is mounted on the side wall of the upper test support, with its output end facing downwards. The upper test slide is connected to the output end of the upper test cylinder and is driven to move up and down by the upper test cylinder. The upper test support plate is horizontally mounted on the upper test slide. The test pieces include at least two sets, which are spaced apart on the upper test support plate and descend with the upper test support plate to connect to the battery.

[0006] Preferably, the test piece includes a test base and a test head, wherein the test base is disposed at the bottom of the upper test support plate, and the bottom of the test base is provided with a strip-shaped slide bar; the top of the test head is provided with an adjustment structure groove, and the test head is connected to the lower part of the test base by sliding into the slide bar through the groove; the test head is provided with at least two test holes, and the test holes extend through the test head vertically.

[0007] Preferably, the test piece further includes a PCB board and test probes; wherein, the PCB board is disposed on the top of the upper test support plate; the test probes include at least two probes, the tops of the at least two test probes are connected to the PCB board, and the test probes pass downward through the test base and test head, and through the test hole, so as to be inserted into the battery.

[0008] Preferably, the test seat is connected to the bottom of the upper test support plate via an inverted connecting post, with a gap between the test seat and the upper test support plate. A spring is installed in this gap, with its two ends abutting against the upper test support plate and the test seat, respectively. The test seat and the connecting post are slidably connected, and the spring provides elastic cushioning.

[0009] A testing device including a quick-release floating battery test head.

[0010] Preferably, the device further includes a test bracket and a pre-compression component. The test bracket is mounted on the test platform of the test machine, and a through mounting slot is provided in the middle of the test bracket. The pre-compression component includes at least two sets, which are hung upside down on the lower part of the top plate of the test bracket for pre-compressing the battery. The battery floating test head includes at least two sets, which are mounted on the test bracket and extend downward through the mounting slot for connecting the battery from above.

[0011] Preferably, the pre-compression component includes a connecting column, a pre-compression support, an elastic column, a flexible pre-compression block, and a pre-compression head, wherein the connecting column is connected to the test bracket; the pre-compression support is disposed at the bottom of the connecting column; the flexible pre-compression blocks are spaced apart below the pre-compression support and are flexibly connected to the pre-compression support through the elastic column; the pre-compression head includes at least two, and at least two pre-compression heads are disposed at the bottom of the flexible pre-compression block.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention addresses the shortcomings and deficiencies of existing technologies by independently developing and designing a floating battery test head and its testing device. This device features a protective outer jacket structure for the test head, effectively protecting the test probe and possessing a flexible pre-compression function. It achieves local pre-compression and leveling of the battery surface before testing, effectively improving insertion position accuracy, insertion success rate, and efficiency.

[0014] This invention aims to provide a testing process in the manufacturing process of power batteries, specifically for connecting batteries to a test circuit via multiple test probes in an automated testing process. Because the connectors on the battery require multiple test probes to be inserted into the test circuit, and due to the small probe holes and the need to simultaneously connect multiple probes, bending or breakage of the test probes is highly likely during the insertion process, leading to test circuit connection failure. To address this, the testing device of this invention uses a test support as a support frame. Multiple pre-compression components and a floating battery test head are simultaneously installed at the bottom of the top plate of the test support. The pre-compression components are used to pre-compress and flatten the battery from above before testing, ensuring the overall flatness of the battery before connecting the test probes and maintaining positional stability during testing. The floating battery test head... The test head is used to insert into the battery connector from above via a test probe. Specifically, the floating battery test head uses an upper test support as its supporting structure. The upper test support is located on the edge of the mounting slot of the test bracket, and its side wall is equipped with an upper test cylinder to provide linear power in the vertical direction to drive the upper test slide to move the upper test support plate up and down. A key feature is that the upper test support plate of this invention has a set of test pieces, with a test base as the connecting structure. The bottom of the test base has a strip-shaped sliding bar. The test head connects to the test base by interlocking with the sliding bar through a groove in the strip-shaped structure at its top. During installation, the test head slides into the sliding bar through the groove. The device allows for quick assembly and disassembly. After the test head slides into place, it can be secured to the test base with screws. The test head has multiple through-holes corresponding to the test probes. The tops of the multiple test probes are connected to the PCB board located on the upper part of the upper test support plate, and extend downwards through the test base into the test holes. The inner diameter of the test hole is larger than the outer diameter of the test probe, allowing the test probe to slide freely vertically within the test hole. During testing, this method of using test holes to cover the outside of the test probe protects it from bending, deformation, or breakage. Furthermore, the test base and the upper test support plate of this invention are connected by a flexible connection that allows vertical movement. The method utilizes a spring to provide flexible elasticity, allowing the test head located below it to have flexible movement space in the vertical direction. In its natural state, the spring force pushes the test base and test head downwards, causing the test probe to retract into the test hole. During the test, as the test support plate descends and approaches the battery, the test head first contacts the battery surface, providing local pre-compression and leveling of the battery connector position before testing, ensuring the local flatness of the test probe when it is inserted into the connector. As the battery support plate continues to descend, the bottom surface of the test head is subjected to the upward force of the battery, compressing the spring upwards, causing the test probe to gradually extend from the test hole and insert into the connector, completing the insertion action.
