[0046] a, control the detection driver 452 of the magnet detection mechanism 450 to drive the magnetic induction sensor 451 to approach the adapter 2 to detect whether the electromagnetic lock matched with the gun head 1 is installed in the adapter 2, and then control the detection driver 452 of the magnet detection mechanism 450 to drive the magnetic induction sensor 451 to reset. If the detection result is yes, execute step b; if the detection result is no, stop detection and alarm.

[0047] b, control the gun head driving part 220 to drive the gun head 1 to insert into the adapter 2, and determine whether the gun head 1 is inserted in place according to the pushing force of the first force sensor 411 and the stroke of the gun head driving part 220.

[0048] c, control the charging base driving part 320 to drive the charging base 3 to plug into the adapter 2; determine whether the charging base 3 is plugged in place according to the pushing force of the second force sensor 412 and the stroke of the charging base driving part 320. If the detection result is yes, execute step d; if the detection result is no, stop detection and alarm.

[0049] d, control the charging base driving part 320 to pull out the charging base 3, and determine whether the charging base 3 is locked according to the pulling force of the second force sensor 412. If the detection result is yes, control the charging base driving part 320 to drive the charging base 3 to return to the position before pulling out and execute step e; if the detection result is no, stop detection and alarm.

[0050] e, control the gun head driving part 220 to pull out the gun head 1, and determine whether the gun head 1 is locked according to the pulling force of the first force sensor 411. If the detection result is yes, control the gun head driving part 220 to drive the gun head 1 to return to the position before pulling out and execute step f; if the detection result is no, stop detection and alarm.

[0051] f, control the gun head end unlocking mechanism 500 to unlock the gun head 1, and then control the gun head driving part 220 to pull out the gun head 1 again. Determine whether the gun head 1 is abnormally locked according to the pulling force of the first force sensor 411. If the detection result is yes, stop detection and alarm; if the detection result is no, control the gun head driving part 220 to drive the gun head 1 to reset; and then execute step g.

[0052] g. Control the unlocking mechanism 600 at the charging base end to unlock the charging base 3, and control the driving part 320 of the charging base to pull the charging base 3 again. Determine whether the charging base 3 is abnormally locked according to the magnitude of the force of the second force sensor 412.

[0053] S5. Record and feedback the detection results of each sub-step in step S4. When the detection of a sub-step in step S4 is interrupted and an alarm is triggered, the operator controls the charging gun adapter function test device to reset, removes adapter 2 and places it in the unqualified area; when the detection ends and a qualified signal is fed back, the operator removes adapter 2 and places it in the qualified area.

[0054] S6. Repeat steps S1 to S5 until all adapters to be tested have been tested.

[0055] In sub-step b of this embodiment, the stroke of the gun head drive unit 220 is calculated by the rotation angle of the first servo motor 221 and the lead screw lead of the first lead screw slider module 222. Limit switches can also be used to control the maximum stroke and reset point. When the stroke of the gun head drive unit 220 does not reach the target stroke and the thrust of the first force sensor 411 exceeds the preset value, it is determined that the gun head 1 is not inserted in place. When the stroke of the gun head drive unit 220 reaches the target stroke and the thrust of the first force sensor 411 does not exceed the preset value, it is determined that the gun head 1 is inserted in place.

[0056] In sub-step c, the stroke of the charging base drive unit 320 is calculated by the rotation angle of the second servo motor 321 and the lead screw lead of the second lead screw slider module 322. Limit switches can also be used to control the maximum stroke and reset point. When the stroke of the charging base drive unit 320 does not reach the target stroke and the thrust of the second force sensor 412 exceeds the preset value, it is determined that the charging base 3 is not inserted in place. When the stroke of the charging base drive unit 320 reaches the target stroke and the thrust of the second force sensor 412 does not exceed the preset value, it is determined that the charging base 3 is inserted in place.

[0057] For example, if the minimum insertion stroke of the charging head is set to 50mm and the resistance limit during insertion is 50N, then if the insertion stroke of the charging head 1 is less than 50mm but the resistance value detected by the first force sensor 411 is greater than 50N, it indicates that the insertion of the charging head 1 into the adapter 2 is abnormal, and it is determined that the charging head 1 is not fully inserted, thus stopping the detection and triggering an alarm. If the resistance value detected by the first force sensor 411 during the insertion of the charging head 1 is always less than or equal to 50N, and the charging head 1 eventually completes the entire insertion stroke, then it indicates that the insertion process is normal and the charging head 1 is fully inserted. The detection logic for the plugging process of the charging base 3 is the same as the detection logic for the insertion process of the charging head 1.

[0058] When step b is performed, the gun head end unlocking mechanism 500 is controlled to unlock the gun head locking piece of the adapter 2, and after step b is completed and before step c is performed, the gun head end unlocking mechanism 500 is reset.

[0059] When step c is performed, the charging seat end unlocking mechanism 600 is controlled to unlock the charging seat locking piece 8 of the adapter 2, and after step c is completed and before step d is performed, the charging seat end unlocking mechanism 600 is reset.

[0060] In this way, the resistance of the gun head 1 and the charging seat 3 when connected with the adapter 2 can be eliminated, the uncertainty in the execution of steps b and c caused by the change of the resistance can be eliminated, and the detection accuracy can be improved.

[0061] It can be seen that when the adapter 2 is tested by using the charging gun adapter function test device, the operator only needs to complete the loading and unloading work of the adapter 2, the operation process is extremely labor-saving, and in the later stage, the operator work can be replaced by a mechanical grab, the detection intelligence and automation are further improved, the uncertainty of manual inspection is eliminated, and the detection efficiency and detection quality are improved.

[0062] The above embodiments only exemplarily illustrate the principles and effects of the present application and some applied embodiments, and are not used to limit the present application; it should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
