[0020] In the embodiment of the present disclosure, the physical parameter test assembly comprises an industrial camera and a communication electronic balance; the electrical performance parameter test assembly comprises a multimeter, an ohmmeter and an insulation meter; the tool seat is provided with a foolproof assembly.

[0021] In the embodiment of the present disclosure, the model of the program-controlled direct current power supply is UDP6720; the model of the multimeter is VICTOR 8265; the model of the insulation meter is TH2683A; the model of the milliohm meter is Agilent 34460A; the model of the relay is KBCA132S; the model of the serial server is ZLAN5843A; the model of the industrial camera is ME2L-505-36U3M / C(-L); the parameter of the communication electronic balance is 600g / 0.01; the model of the laser marking module is KEWEIDUN4.5W.

[0022] When testing, the laser marking module is used to mark a unique code for the drive module. After starting the test, the pins of the drive module are placed in the tool seat and locked, and the drive module is first subjected to the marking process. The industrial computer controls the laser marking module to move to a fixed position above the drive module, and according to the production batch and serial number combination, the drive module is subjected to the marking operation, and the test data of the drive module and the marked unique code have a unique corresponding relationship.

[0023] The weight and size of the drive module are tested by the physical parameter test assembly. After the marking is completed, the communication electronic balance obtains the transmitted weight value, subtracts the basic weight value, and the weight of the drive module is obtained, which is recorded in the physical property test data. The industrial camera can calculate the length, width and height of the drive module by adjusting the front view and side view, and record them in the physical property test data.
