Description of the new product features(Battery stripping test section)

1）Big test platform: it can meet the installation and test of various specifications of mainstream assembly manufacturers in the current market.

2）Impact prevention device: The sample installation platform has added a special anti-impact device, which can effectively protect the impact between the sample platform and the fixture, and can intelligently sense the impact, control the operation of the equipment online, and protect the sensor.

3）carefully design the test detail components

In the industry application practice for many years, the installation and adjustment parts of the equipment test fixture and sensor have been carefully designed:

• Test fixture height adjustment to apply battery testing of different specifications;

• Adjust the horizontal Angle of the test fixture to obtain the most suitable stripping test Angle for testing, which can be closer to the force direction in the actual application of the pattern, and the data is more accurate;

• Vernier-type sensor position adjustment, the replacement of the test work when the adjustment is more convenient;

• Special mini test jaw is convenient to clamp, small spacing station is also suitable, can be more convenient to clamp short welding belt samples.

Software Function Features

1) Advanced chip integration technology, professionally designed data acquisition and amplification system, has the advantages of high integration, stability and reliable, easy to use and other advantages. The control software can automatically obtain the detection data of tensile strength, fracture strength, stripping strength, elongation rate, and the open formula editing can automatically calculate the force, stress, displacement, deformation and other data results of any specified point in the test process. The control and data processing of the test process meet the requirements of the corresponding national standards for metallic materials and non-metallic materials;

2) Load displacement curve; load and time curve; displacement and time curve; stress and strain curve;

3) Edit the corresponding test standards according to the requirements of various countries for the test films, fill in the test article data, edit the test methods, and provide them for future test selection;

4) Automatically store this test result and edit it as a report printout. There is a formula editing function to compare multiple tested curves;

5) can set the number of decimal points, each physical quantity unit and password protection, etc;

6) automatic clear zero: the computer receives the test start command, the measurement system will automatically clear zero;

7) Automatic regression: automatic identification of the maximum force, the active beam automatically returns to the original position at high speed;

8) automatic archiving: test data and test conditions automatic storage plate, to prevent the loss of data caused by the sudden power failure to forget the deposit plate;

9) test process: the test process and measurement, display, analysis are completed by the microcomputer;

10) Display mode: the data and the curve are dynamically displayed along with the test process;

11) Structure reproduction: the test results can be accessed arbitrarily, and the data curve can be reanalyzed;

12) curve traversal: after the test is completed, the mouse can use the mouse to find out the force value and deformation data of the test curve, which is convenient and practical to find the test data of various materials;

13) Comparison of results: multiple test characteristic curves can be combined, reproduced, amplified and compared with a group of samples;

14) curve selection: according to the need, stress strain, force time and intensity time can be selected for display and print;

15) Batch test: a batch of samples can be completed successively after setting the test with the same parameters;

16) Test report: standard format;

17) limit protection: with program control and mechanical two-level protection;

18) overload protection: when the load exceeds 10% of the rated automatic shutdown;

19) emergency stop: equipped with an emergency stop switch, used for the emergency state to cut off the power supply of the whole machine;

20) automatic diagnosis: the system has the function of automatic diagnosis, regularly on the measurement system, drive the system for overpressure, overcurrent, overtemperature and other inspection, abnormal situation immediately shutdown.

Introduction to the test software

The instrument software is developed for the testing of stripping force, tensile strength and other parameters of silicon material, silicon wafer, cell, battery components and other products, and can realize multi-station test display and display through various report forms. The software can automatically locate, can automatically run to the battery according to different specifications.

The main interface of the software is shown in Figure 1 below. A complete test process consists of three steps: pre-test setup, test, multi-channel graph, and test results presentation:

Figure 2, Test curve (such as stripping, stretching, compression, etc.); determine whether the peak, mean, area and effective length of qualified value can be calculated according to the arbitrary combination of four parameters: peak qualified, mean qualified, area qualified, peak + area, peak + effective length; determine whether the whole cell is qualified according to the ratio of the qualified number divided by the total interval.

Figure 3. Display of test results; can generate excel report automatically, including data and graphics; can automatically generate test data from 5BB, 6BB, 9BB, 12BB, 15BB, 18BB, 20BB, 32BB, EXCEL, PDF, print and export; all test data, and can automatically generate daily, weekly, monthly and annual reports to facilitate data statistics and analysis.
