for ease of understanding, the frequency converters detected in the first detection state and the second detection state are not defined as the first frequency converter 12 and the second frequency converter 13, respectively.
Referring to fig. 3, 7 and 8, when the first transducer 12 is detected, the conveyor belt 31 transports the first transducer 12 to move to the detection position, i.e. the connection terminals of the first transducer 12 correspond to the first input test pin set 72 and the output test pin set 71;
the telescopic device 10 pushes the mounting frame 4, thereby pushing the first support 5, driving the first input test pin group 72 and the output test pin group 71 to move to one side of the first frequency converter 12 and be connected with the connection terminal on the first frequency converter 12, and the limiting member 55 abuts against the lower side of the first frequency converter 12, and pushing the first frequency converter 12, so that the other side of the first frequency converter 12 is in contact with the positioning member 114, and the positioning member 114 is pushed to compress the elastic member 112, until the positioning member 114 is in contact with the outer cylinder 111, and can not contract; at the moment, the first frequency converter 12 is stably limited;
and powering on to perform detection debugging operation.
Wherein, the undetected first frequency converter 12 waits for feeding from the conveying device 14 positioned at the lower side of the conveying belt 31; and the detected first frequency converter 12 is conveyed to the upper conveyer 14 by the conveyer belt 31 for blanking.
Referring to fig. 6 and fig. 9 to fig. 10, when detecting the second frequency converter 13: the conveying device 14 positioned on the upper side of the conveying belt 31 is changed into a feeding conveying belt, the conveying belt 31 positioned on the lower side is changed into a blanking conveying belt, and the second frequency converter 13 is fed by the conveying device 14 positioned on the upper side of the conveying belt 31;
the retractable device 10 retracts the mounting frame 4, so that the first input test needle group 72 and the output test needle group 71 return to the original positions and then are separated from the first frequency converter 12 after detection is completed, at the moment, the retractable device 10 retracts by a section, the gear 94 is meshed with the toothed plate 95, and the square block 96 is inserted into the reducing pipe port 82.
The conveyor belt 31 now conveys the last detected frequency converter one 12 in the opposite direction to the conveyor 14 on the lower side.
During the process that the conveyor belt 31 conveys the last detected frequency converter I12 to the conveying device 14, the supporting roller 32 drives the external thread pipe 83 and the gear 94 to rotate, so as to complete the movement of the second input test needle group 73 to one side of the detection platform 3 and the movement of the output test needle group 71 to the middle part of the detection platform 3;
the telescopic device 10 then pushes the mounting frame 4 to the starting position, disengaging the toothed plate 95 from the gear 94 and moving the block 96 out of the nozzle 82 into the interior of the externally threaded tube 83.
Referring to fig. 3 and fig. 11, the second frequency converter 13 to be detected is loaded onto the conveyor belt 31 from the conveyor 14 located at the upper side;
the conveying belt 31 drives the second frequency converter 13 to move to a detection position, namely, a wiring terminal of the second frequency converter 13 corresponds to the second input test needle group 73 and the second output test needle group 71;
at this time, the telescopic device 10 pushes the mounting frame 4, so that the output test pin group 71 and the second input test pin group 73 are respectively and correspondingly connected with the wiring terminals of the second frequency converter 13, and at this time, the positioning member 114 is in contact with the outer cylinder 111, and the elastic member 112 is in a compressed state;
after the detection is finished, the telescopic device 10 is pulled back, the elastic element 112 is stretched, and the positioning element 114 pushes the second frequency converter 13, so that the second input test needle group 73 can be separated from the input end of the second frequency converter 13, and the conveyor belt 31 can convey the detected second frequency converter 13 conveniently;
when the first frequency converter 12 is detected again, the adjusting gear 94 of the expansion device 10 is meshed with the toothed plate 95 again in the same manner, and then the conveying belt 31 conveys the last detected second frequency converter 13 reversely again, and the conveying directions of the two conveying devices 14 are arranged reversely.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
