The invention also provides a method for testing the shell 200 by using the testing device 100, which comprises the following steps:

s1, carrying out polarity test on the magnet by adopting the polarity test component, and judging whether the polarity of the magnet is correct or not according to a polarity test result;

s2, if the polarity of the magnet is correct, performing tension test on the magnet by using a tension test assembly, and judging whether the magnet is fixed on the shell or not according to the tension test result of the magnet;

s3, if the magnet is fixed on the shell, performing tension test on the iron sheet by using a tension test assembly, and judging whether the iron sheet is fixed on the shell or not according to the tension test result of the iron sheet; and if the iron sheet is fixed on the shell, the test is passed.

Specifically, step S0 is further included before step S1: an operator places the casing 200 to be tested on the first fixing block 221, and the photoelectric switch 24 detects that the casing 200 is placed on the first fixing block 221, so that the first driving cylinder 224 is controlled to drive the second stopper 225 to press the fixing casing 200, and the suction cup 226 sucks the fixing casing 200. After ensuring that the housing 200 is fixed and the optical grating 5 is detected without any problem, the operator presses the two start switches 71 at the same time, and the scanning module 8 binds the housing 200 to the information code on the housing 200.

Specifically, step S1 includes: the two second driving cylinders 231 simultaneously drive the teslameter 232 connected with the two second driving cylinders to move upwards along the Z-axis direction to be close to the magnet 201 on the shell 200, the teslameter 232 performs polarity test on the magnet 201, and whether the polarity of the magnet 201 is installed correctly is judged according to the polarity test result. After the test, the second driving cylinder 231 drives the teslameter 232 away from the housing 200 to reset. If the polarity of the magnet 201 is not installed correctly, directly judging that the magnet is unqualified, and ending the test; if the polarities of both magnets 201 are correctly installed, the test is passed and step S2 is performed.

Specifically, step S2 includes: the first driving assembly 21, the second driving assembly 32 and the third driving assembly 33 are matched to drive the left second tension meter 343 to move to the position right above the right magnet 201, the left third driving cylinder 344 drives the left second tension meter 343 to descend along the Z axis, the second permanent magnet 3433 is fixed with the right magnet 201 in a magnetic attraction manner, and the second driving assembly 32 indirectly applies a gradually increasing force to the left second tension meter 343 to separate the second permanent magnet 3433 from the right magnet 201 for tension test. If the second permanent magnet 3433 is not separated from the right magnet 201 and the right magnet 201 is separated from the housing 200, the test is directly determined to be unqualified and the test is finished; if the right magnet 201 is not yet detached from the housing 200 when the second permanent magnet 3433 is detached from the right magnet 201, it is determined that the right magnet 201 is fixed. After the test is completed, the left third driving cylinder 344 is reset. Similarly, the testing of the left magnet 201 by the right second tension meter 343 is similar to the above steps, and will not be repeated herein, and if the second permanent magnet 3433 is not yet separated from the left magnet 201 and the left magnet 201 is separated from the housing 200, it is determined as being defective and the testing is finished; if the left magnet 201 is not yet detached from the housing 200 when the second permanent magnet 3433 is detached from the left magnet 201, it is determined that the left magnet 201 is fixed and both magnets pass the test, and then step S3 is performed.

Specifically, step S3 includes: the first permanent magnet 3423 on the first tension meter 342 is moved to be fixed with the iron sheet 202 by the cooperation of the first driving assembly 21, the second driving assembly 32 and the third driving assembly 33; the first driving assembly 21 indirectly applies a gradually increasing force to the iron plate 202 through the fixing assembly 22 to separate the first permanent magnet 3423 and the iron plate 202, and performs a tension test. If the first permanent magnet 3423 has not been separated from the iron piece 202 and the iron piece 202 is separated from the case 200, it is determined that the test is failed to be completed, and if the iron piece 202 has not been separated from the case 200 when the first permanent magnet 3423 is separated from the iron piece 202, it is determined that the iron piece 202 is fixed. Through all the tests, the detection result of the housing 200 is determined to be qualified.

In other embodiments, a preset value may be set, a preset force is applied to the tensile testing assembly 34, and if the magnet 201 and the iron sheet 202 are not separated from the housing 200, it is determined that the magnet 201 and the iron sheet 202 are fixed to the housing 200; if the magnet 201 and the iron piece 202 are not separated from the housing 200 yet to reach the preset value, it is determined that the magnet 201 and the iron piece 202 are not fixed to the housing 200.

Further, the test result of each step is output to the control module 9 in real time for the operator to monitor in real time.
