Description

Technical Field

[0001] This utility model relates to the field of battery basic parameter measurement technology, and in particular to a high-precision basic parameter measurement device based on PLC. Background Technology

[0002] A Programmable Logic Controller (PLC) is a digital electronic system specifically designed for industrial applications. It employs a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations. Through digital or analog inputs and outputs, it controls various types of machinery or production processes. PLCs offer advantages such as high reliability, ease of programming, flexible configuration, a complete range of input / output modules, convenient installation, and fast operation.

[0003] Before batteries enter the testing and shelf-mounting stage, photos and dimensional information of the incoming batteries need to be measured and recorded to ensure that the batteries meet the standards provided by the manufacturer. Currently, most pre-testing relies on manual labor, using mobile phones, cameras, etc. to take photos, requiring two people to complete the task. One person manually uses calipers to measure the side beam, while the other manually records the data. The testing process consumes a lot of manpower and time. Subsequent data processing and judgment are also time-consuming and labor-intensive. Furthermore, variations in the force applied during dimensional measurement lead to significant deviations in test results, affecting the accuracy of the test data. Due to the sharpness of the calipers and their metal material, the batteries can easily slip or short-circuit during measurement, posing certain safety risks and hindering quality traceability and data management during battery testing.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a high-precision basic parameter measurement device based on PLC. Utility Model Content

[0054] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0055] See Figures 1 to 6 As shown;

[0056] This embodiment discloses a high-precision basic parameter measuring device based on a PLC, the measuring device comprising:

[0057] The main body of the device has a controller section 1 on one side and a measuring platform 2 at the bottom.

[0058] Multiple ranging units integrated at different locations on the main body of the device; and

[0059] Camera 402 is integrated into the upper part of the device body;

[0060] The battery 10 is placed on the measuring platform 2 of the main body of the device, and the dimensions of the corresponding side of the battery 10 are measured from different directions by the ranging unit.

[0061] The controller section 1 integrates a PLC, and the ranging unit and camera 402 both communicate with the PLC;

[0062] The camera 402 transmits the captured photo of the battery 10 to the PLC, and the ranging unit transmits the measured size of the corresponding side of the battery 10 to the PLC and compares it with the information recorded in the PLC.

[0063] Specifically, this embodiment discloses a measuring device based on PLC and multi-component communication to automatically measure the basic dimensions of battery 10. It includes a main body, multiple ranging units and a camera 402. The multiple ranging units and the camera 402 all transmit the corresponding data information they acquire through PLC communication in the controller part 1. After the data information is transmitted to the PLC, it is compared with the information pre-stored in the PLC to determine whether the battery 10 is within the deviation range and to give certain feedback information.

[0064] Preferably, the surface of the measuring platform 2 in this embodiment has a battery holder protruding from the measuring platform;

[0065] The battery holder has at least two holding parts 3 that abut against two adjacent sides of the bottom surface of the battery 10; the holding parts 3 abut against the corresponding sides of the bottom surface of the battery 10 to position the battery 10.

[0066] First, before measuring the basic parameters of battery 10, it is necessary to position battery 10. Therefore, the measuring platform 2 in this embodiment has a protruding battery holder. Preferably, the battery holder in this embodiment consists of two L-shaped holder parts 3. That is, the two L-shaped holder parts 3 are used to position the two sides of the bottom surface of battery 10, thereby achieving the positioning of battery 10. After positioning, the basic parameters are obtained using the ranging unit and camera 402 mentioned above.

[0067] Preferably, the controller section 1 in this embodiment is configured to extend vertically; a screen 101 is integrated on the upper part of the controller section 1, and the screen 101 is connected to the PLC. For ease of operation, the device in this embodiment can input preset data through the screen 101, and the feedback after measurement and comparison can also be displayed more intuitively through the screen 101.

[0068] Preferably, in this embodiment, the measuring platform 2 has a horizontally extending structure;

[0069] The camera 402 is selected from the Barrence Ace 2 series camera 402;

[0070] The camera 402 is integrated into the upper part of the controller part 1 via the camera mounting bracket 401 and is located directly above the battery 10 placed on the measuring platform 2.

[0071] First, the camera 402 mainly takes pictures of the battery 10 and transmits the captured image information to the PLC and stores it in the PLC. The integration of the camera 402 can save the problems caused by manual hand-held camera shooting, make the shooting angle uniform, save manpower, and achieve higher accuracy.

[0072] Preferably, the main body of the device in this embodiment integrates three sets of ranging units, and the three sets of ranging units are used to measure the length, height and thickness of the battery 10, respectively; the ranging units are slidably connected to the main body of the device through a sliding component.

[0073] In this embodiment, the ranging unit uses a laser ranging sensor, specifically the Keyence 1L-100. This type of laser ranging sensor supports RS-485, EtherNet / IP, or Modbus TCP, making it easy to integrate with a PLC.

[0074] The three laser rangefinders in this embodiment are the first laser rangefinder 501, the second laser rangefinder 502, and the third laser rangefinder 503.

[0075] Based on the above selection of laser ranging sensor, the first laser ranging sensor 501 in this embodiment is slidably connected to the upper part of the controller part 1 through a sliding component, and the first laser ranging sensor 501 can slide along the width direction of the controller part 1. The first laser ranging sensor 501 is used to measure the height of the battery 10.

[0076] First, in this embodiment, the first laser ranging sensor 501 is slidably connected to the upper part of the controller part 1, and it can slide left and right through the sliding component. After the battery 10 is positioned by the battery holder, the first laser ranging sensor 501 is located directly above the battery 10. When the laser emitted by the first laser ranging sensor 501 is positioned at the upper end of the battery 10, a data is measured. As the first laser ranging sensor 501 moves, the laser moves away from the battery 10 and hits the surface of the measuring platform 2, and another data is measured. Thus, the height data of the battery 10 can be obtained by the difference between the two measuring points, and the height data is transmitted to the PLC for storage and comparison.

[0077] Secondly, in this embodiment, the second laser rangefinder 502 is slidably connected to one side of the long side of the measuring platform 2 via a sliding assembly, and the second laser rangefinder 502 slides along the long side of the measuring platform 2 via the sliding assembly to measure the length of the battery 10.

[0078] Similar to the principle of the first laser rangefinder 501, the second laser rangefinder 502 in this embodiment is slidably connected to one side of the long side of the measuring platform 2. As the second laser rangefinder 502 moves, one end of it moves to the other end along the length direction of the battery 10, thereby obtaining data from two points. The length data of the battery 10 can be obtained from these two points, and the length data is transmitted to the PLC for storage and comparison.

[0079] Finally, in this embodiment, the third laser rangefinder 503 is slidably connected to one side of the short side of the measuring platform 2 via a sliding assembly, and the third laser rangefinder 503 slides along the short side of the measuring platform 2 via the sliding assembly to measure the thickness of the battery 10.

[0080] Similar to the first laser rangefinder 501 and the second laser rangefinder 502, the third laser rangefinder 503 in this embodiment moves along the width direction of the measuring platform 2 to measure the thickness of the battery 10.

[0081] Before testing, the standard dimensions and deviation information of battery 10 are entered into the host computer interface, and the position of each laser rangefinder is adjusted. Then, the battery barcode is entered into the host computer interface, and the start button is clicked. After measurement, the dimension data and the captured photos are transmitted to the PLC, which is used to determine whether they are within the deviation range and finally provides feedback.

[0082] As a preferred embodiment of the sliding component, the sliding component includes a guide rail 601 integrated into the corresponding position of the device body; and a slider 602 that slides with the guide rail 601; the laser rangefinder is connected to the corresponding slider 602 through a sensor mounting rod.

[0083] In this embodiment, the guide rail 601 is selected from the SGR10E series; the slider 602 is selected from the SGB10 series.

[0084] Preferably, the PLC used in this embodiment is a Siemens S7-1200 model PLC.

[0085] In the above technical solution, the high-precision basic parameter measuring device based on PLC provided by this utility model has the following beneficial effects:

[0086] The purpose of this utility model is to free up the hands of testing personnel by using PLC and high-precision sensors. It can input the design standards and deviations of the same batch of batteries 10, automatically record the test information, judge and save the backup, and output the results in commonly used Excel or Word formats, which facilitates data processing, saves manpower and time, improves work efficiency, and enhances the user experience.

[0087] The device of this invention is free from external interference such as external force during testing, reducing the influence of force on the size of battery 10 during the measurement process to zero, thereby making the test data more accurate and more consistent.

[0088] The device of this invention effectively eliminates interference from human factors, realizes non-contact measurement, improves measurement safety, and ensures the reliability of the device.

[0089] The foregoing description only illustrates certain exemplary embodiments of the present invention.
