Description

Technical Field

[0001] This utility model relates to the field of batteries, and in particular to a multi-dimensional measuring device for square batteries. Background Technology

[0002] Square-shaped single-cell batteries are widely used in new energy vehicles, energy storage systems, and other fields. Their polarity, size (such as thickness), and weight are important parameters related to battery safety, consistency, and energy density, and must be rigorously tested before leaving the factory.

[0003] Currently, the industry typically uses separate equipment to perform the above three tests: using a voltage and internal resistance meter to determine polarity, using a digital caliper to measure dimensions, and using an electronic balance to weigh. This decentralized testing method has significant drawbacks: the operation process is cumbersome, requiring repeated battery removal and placement, resulting in low testing efficiency; furthermore, manual reading of the scale is prone to introducing errors, affecting the accuracy and reliability of the measurement results.

[0004] In addition, existing measuring equipment (such as some dedicated size measuring instruments) has limited functionality, cannot integrate the three tests, and is difficult to adapt to batteries of different specifications and with different terminal positions, resulting in poor versatility. Utility Model Content

[0005] The purpose of this invention is to provide a multi-dimensional measuring device for square batteries, which integrates a weight testing unit, a size measuring unit, and a polarity measuring unit into one unit, and utilizes a multi-directionally adjustable test connector to achieve efficient and accurate integrated measurement of the weight, size, and polarity of square batteries.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multi-dimensional measurement device for square batteries, comprising: The weight testing unit includes a base plate for placing the battery and detecting its weight; The size measuring unit includes a bracket mounted on the base plate and a distance measuring instrument mounted on the bracket; The polarity measuring unit includes a gantry that is horizontally slidably connected to the base plate and a crossbeam that is vertically slidably connected to the gantry; both ends of the crossbeam are vertically slidably connected to the gantry; and a horizontal first groove is provided on the crossbeam.

[0007] A further solution: the distance detector is an infrared distance sensor; the infrared distance sensor is communicatively connected to the base plate.

[0008] A further solution: The support is an L-shaped cantilever beam, and the distance detector is located on the horizontal section of the L-shaped cantilever beam.

[0009] A further embodiment: the polarity measurement unit also includes a test connector for connecting a voltage internal resistance meter, the test connector being disposed on the first slide groove.

[0010] A further embodiment: the test connector passes through the first groove and is slidably connected to it.

[0011] A further solution: The base plate is provided with second sliding grooves on both sides, and the two ends of the gantry are slidably connected to the second sliding grooves.

[0012] A further embodiment: a third sliding groove is provided on two opposite sides of the gantry, and the end of the crossbeam is slidably connected to the third sliding groove; the lowest end of the third sliding groove is set higher than the plane height of the base plate.

[0013] A further solution: The base plate has a built-in weight sensor and a digital display; the weight sensor and the distance detector are both communicatively connected to the digital display.

[0014] Compared with the prior art, the beneficial effects of this utility model are: By integrating the weight testing unit, dimensional measurement unit, and polarity measurement unit into a single device, the traditional fragmented operation mode, which required separate operation of an electronic balance, calipers, and voltage and internal resistance meter, has been transformed. Operators only need to place the battery on the base plate to complete all three tests sequentially at a single workstation, greatly simplifying the operation steps, shortening the testing time, and effectively solving the problems of time-consuming, labor-intensive, and inefficient existing technologies.

[0015] In terms of measurement performance, this solution achieves non-contact, precise measurement of any point on the battery surface by introducing an infrared distance detector, overcoming the limitation of traditional calipers that can only measure a single point. Simultaneously, the polarity testing unit, through a gantry, crossbeam, and first slide groove, forms a multi-degree-of-freedom adjustment system, allowing the test connector to adapt to batteries of different sizes and terminal positions, ensuring reliable contact and accurate measurement. The built-in digital display automatically displays the data, avoiding errors from manual interpretation.

[0016] In summary, this device not only significantly improves testing efficiency through integrated design, but also enhances testing quality and versatility through precise and adaptive design. It effectively reduces labor costs and operational complexity, providing reliable equipment support for the large-scale, high-quality production and testing of prismatic batteries.

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.

Therefore, they should not be construed as limitations on this utility model.

[0020] Please see Figure 1-2 In this embodiment, a multi-dimensional measurement device for a square battery includes a weight testing unit, a size measurement unit, and a polarity measurement unit, wherein: The weight testing unit includes a base plate 2 for placing and testing the weight of battery 1; The dimension measuring unit includes a bracket 3 mounted on the base plate 2 and a distance measuring instrument 4 mounted on the bracket 3; The polarity measuring unit includes a gantry 5 that is horizontally slidably connected to the base plate 2, and a crossbeam 6 that is vertically slidably connected to the gantry 5; both ends of the crossbeam 6 are vertically slidably connected to the gantry 5; and a horizontal first groove 7 is provided on the crossbeam 6.

[0021] By integrating the weight testing unit, size measurement unit, and polarity measurement unit into one unit, and through the cooperation of the base plate 2, bracket 3, distance detector 4, gantry 5, crossbeam 6, and first slide groove 7, the integrated measurement of the three key parameters of battery 1—weight, size, and polarity—is realized, solving the problems of requiring multiple devices, cumbersome operation, and low efficiency in the existing technology.

[0022] Furthermore, the distance detector 4 is an infrared distance sensor. By using an infrared distance sensor as the distance detector 4, non-contact and accurate distance measurement of any position on the surface of the battery 1 is achieved, avoiding potential damage to the battery surface or measurement errors caused by contact measurement, and more accurately reflecting the overall size and contour of the battery 1.

[0023] Furthermore, the bracket 3 is an L-shaped cantilever beam, and the distance measuring instrument 4 is installed on the horizontal section of the L-shaped cantilever beam. By setting the bracket 3 as an L-shaped cantilever beam structure and installing the distance measuring instrument 4 on its horizontal section, a stable and wide measurement field of view is provided for the distance measuring instrument 4, ensuring that it can scan and measure any point on the top surface of the battery 1 placed on the base plate 2 without obstruction, thereby improving the flexibility and accuracy of dimensional measurement.

[0024] Furthermore, the polarity measurement unit also includes a test connector 8 for connecting a voltage internal resistance meter, the test connector 8 being disposed on the first slide groove 7. By setting the test connector 8 on the first slide groove 7, the position of the test connector 8 can be flexibly adjusted in the horizontal direction, thereby adapting to batteries 1 with different terminal spacings, ensuring that the test connector 8 can accurately and reliably contact the positive and negative terminals of the battery 1 to complete the polarity test.

[0025] Furthermore, the test connector 8 passes through and slides into the first groove 7. This sliding connection between the test connector 8 and the first groove 7 enables smooth and precise linear movement of the test connector 8 on the crossbeam 6, facilitating quick and accurate positioning of the test connector 8 directly above the terminal post of the battery 1 by the operator, thus improving operational convenience and positioning accuracy.

[0026] Furthermore, the base plate 2 is symmetrically provided with second sliding grooves 9 on both sides, and the two ends of the gantry 5 are slidably connected to the second sliding grooves 9. By sliding the second sliding grooves 9 on both sides of the base plate 2 with the gantry 5, the entire polarity measuring unit can move along the length or width of the battery 1, further expanding the adjustment range of the test connector 8, making it adaptable to batteries 1 of different sizes and specifications, and enhancing the versatility of the device.

[0027] Furthermore, a third slide groove 10 is provided on two opposite sides of the gantry 5, and the end of the crossbeam 6 is slidably connected to the third slide groove 10; the lowest point of the third slide groove 10 is set higher than the plane height of the base plate 2. Through the slidable connection between the end of the crossbeam 6 and the third slide groove 10 on the gantry 5, the vertical height adjustment of the crossbeam 6 and the test connector 8 is achieved. The design of the lowest point of the third slide groove 10 being higher than the plane of the base plate 2 effectively prevents the crossbeam 6 or the test connector 8 from colliding with the battery 1 placed on the base plate 2 during descent, thus preventing any impact on the accuracy of the weight measurement data and ensuring operational safety and the safety of the battery 1.

[0028] Furthermore, the base plate 2 has a built-in weight sensor and a digital display 11; the weight sensor and the distance detector 4 are both communicatively connected to the digital display 11. By embedding the weight sensor in the base plate 2 and connecting it together with the distance detector 4 to the digital display 11, automatic acquisition and centralized digital display of weight and size measurement data are achieved, avoiding visual errors and recording mistakes caused by manual reading of scales, and significantly improving the accuracy and reading efficiency of test results.

[0029] In use, the square single-cell battery 1 to be tested is first placed on the base plate 2 of the device. The weight of battery 1 is automatically detected by the weight sensor built into the base plate 2 and displayed on the digital display 11. Battery 1 is moved to a position directly below the distance measuring instrument 4 on the bracket 3. The orientation of battery 1 can be changed according to actual needs to measure its length, width, and height; the dimensional data will be displayed simultaneously on the digital display 11. The sliding gantry 5 is adjusted to its front-to-back position, and the sliding crossbeam 6 is adjusted to its vertical height. The test connector 8 is moved to its horizontal position on the first slide groove 7, ensuring that the two test connectors 8 accurately and vertically contact the positive and negative terminals of battery 1. The test connectors 8 are connected to an external voltage and internal resistance meter to read and record the voltage and internal resistance values ​​to determine polarity. After obtaining the weight, dimensions, and polarity data of battery 1 in one go, it is removed from the base plate 2.
