Interpretation of the method used by the toy burning tester to test the length

The invention relates to a method for detecting a length parameter related to the flammability of toys. The method is used for the safety inspection and detection of the import and export of toy products, and is used in the product quality inspection and testing of manufacturers producing toys, belonging to the technical field of detection. . The import and export of toys must undergo a series of inspections of corresponding standards, and flammability inspection is an important part of them. In the process of testing the combustion performance of toys, various standards require to test the length of the toy, the length of the beard, etc., and the length of the burned part, and require high test accuracy; various standards also have requirements for the ignition position. move and position to find the best ignition position; various standards have strict requirements on the time to complete the entire flammability test process. Therefore, in the toy flammability test process, it is required that the test length should be high in precision and the speed should be fast, and the positioning height of the flame nozzle should be accurate and fast. At present, in the toy flammability test, the test of the length of the toy, the length of the beard, etc., and the length of the burned part are almost entirely manual. Generally, the steel ruler is fixed on the mechanism of the hanging toy, which is determined by the tester. After testing the reference point, observe the length value to be tested by eye. This test method results in low test reading, slow speed, poor repeatability, low efficiency, and large workload. It is difficult to accurately measure the height of the toy and the size of the burnt part, especially when testing large toys (soft toys with a height greater than 520mm). Therefore, it is very necessary to develop a test method that can complete the test accurately, quickly, automatically and at a low cost. The technical problem to be solved by the present invention is: to provide a method for testing the length on the toy combustion tester, which is used to detect many parameters related to the length in the toy testing process, and these parameters related to the length include the length of the toy, the beard, etc For parameters such as the protruding length of the beard of the toy, the length of the burned part of the toy, and the height of the ignition position, this method should have the advantages of high detection length accuracy, fast testing speed, accurate positioning of the flame nozzle, and fast positioning speed. To this end, the present invention discloses a method for testing the length on a toy combustion tester, which includes the following steps: Step 1, use the center point of the stylus on the test object mechanism as a positioning reference point to set the test object mechanism on the test object mechanism. The set photoelectric switch is the reference point of the test object, and the photoelectric switch set on the test mechanism is the test reference point; controlled by the control system, the vertical slider device on the test object mechanism moves to the test object reference point, and the vertical slide of the test mechanism is controlled by the control system. The block mechanism moves to the test reference point; in step 2, hang the toy under test on the test object mechanism, control the vertical slider device on the test object mechanism to move, and stop the mechanism when the test bottom of the toy under test is aligned with the positioning reference point. Operation; step 3, control the vertical slider device on the testing mechanism to move, and the ruler installed on the vertical slider device of the testing mechanism moves accordingly, so that the ruler moves to the upper position where the toy to be tested is to be tested, and the control system records the test mechanism. The moving distance of the vertical slider device. Preferably, the second step further includes step A: hanging the toy under test on the test object mechanism, the flame nozzle ignites and burns at the best ignition position, so that the toy under test completes the combustion test required for the test, and then controls the test object The vertical slider mechanism on the mechanism moves. The method of the present invention, including this step, can be used to perform a burnt section length test. Preferably, the step A further includes a step B: hanging the toy to be tested on the test object mechanism, moving the vertical slider device on the test object mechanism, and cooperating with the moving ignition device, that is, moving the ignition nozzle to make the test object mechanism move. The most flammable part of the toy is in the best burning position, that is, the most flammable part is within the effective distance in front of the nozzle, ignite and burn, and when the burning is completed, the control system records the moving distance of the vertical slider device on the test object mechanism, and then repeats step one. The method of the present invention including this step can be used to complete the test of the ignition position height of the flame nozzle. The beneficial effects of the present invention compared to the prior art are as follows: the present invention is a method for testing length on a toy combustion tester, and the method can be used to detect many length-related parameters in the toy testing process, and these length-related parameters include a toy It has the characteristics of high detection length accuracy, fast test speed, accurate positioning of the flame nozzle, and fast positioning speed. In order to complete the test of the length of the burned part of the toy, step 2 also includes step A: hang the toy to be tested on the test object mechanism, and the flame nozzle ignites and burns at the best ignition position, so that the toy to be tested can complete the combustion test required for the test. ,Then control the vertical slider device on the test object mechanism to move. The method of the present invention, including this step, can be used to perform a burnt section length test.
