When a capacitor is used for temporary power supply, a variable resistor can be set in series with the capacitor in the power supply detection box 3, and the resistance value of the series resistor changes from high to low, so that the external voltage of the capacitor is more stable.

[0034] A negative pressure tube 414 is fixedly installed on the inner plate 405, and a split piston 415 and a connecting disk 416 are arranged in the negative pressure tube 414.

A return spring 420 is sleeved on the push cylinder shaft 407. The return spring 420 applies an elastic thrust to the synchronous control plate 419, so that the synchronous control plate 419 has a tendency to elastically move in the direction of the spring support plate 408.

[0036] A one-way exhaust valve 421 is embedded on the inner plate 405, and the one-way exhaust valve 421 is connected to the negative pressure pipe 414. The one-way exhaust valve 421 allows the airflow to flow from the negative pressure pipe 414 to the outside in one direction. A negative pressure control pipe 422 is fixedly installed on the inner plate 405, and the negative pressure control pipe 422 is connected to the negative pressure pipe 414. An electromagnetic valve 423 is provided on the negative pressure control pipe 422.

[0037] A hopper bottom cavity 424 is provided at the bottom of the cache hopper 401. A bottom hole 425 is formed through the bottom of the cache hopper 401. The bottom hole 425 is connected to the hopper bottom cavity 424. A separation filter membrane 426 is provided in the hopper bottom cavity 424. A connecting nozzle 427 is provided on the surface of the hopper bottom cavity 424 and is connected to the lower part of the separation filter membrane 426. The connecting nozzle 427 is connected to the negative pressure control tube 422 through a pipeline. A distance sensor 428 is fixedly provided on the inner plate 405. The distance sensor 428 is used to detect the power supply detection box 3.

[0038] Support prisms 101 are fixedly provided on the belt surface of the conveyor belt 1, and the central control host 2 is supported by the support prisms 101. Through the support of the support prisms 101, the bottom raised part of the central control host 2 is located between the two groups of support prisms 101, so that the central control host 2 can be placed horizontally. A telescopic control part 501 and a detection sensor 503 are provided on the horizontal control compartment 5, and an electromagnet module 502 is fixed on the telescopic control part 501.

[0039] When the testing device of the present invention is in use, the central control host 2 is transported on the conveyor belt 1, and the position of the central control host 2 is detected by the detection sensor 503. When the central control host 2 corresponds to the positioning side wall mold 4, the conveyor belt 1 stops running. At this time, the telescopic control part 501 extends to push the central control host 2 to be stuck in the positioning side wall mold 4.

[0040] The insertion cylinder 413 extends out, pushing the power supply detection box 3 out of the push-out port 403, so that the audio output plug 6 of the power supply detection box 3 is plugged into the audio output slot 201, the audio input plug 7 is plugged into the audio input slot 202, and the power supply plug 8 is plugged into the power supply slot 203. The audio output slot 201 and the audio input slot 202 of the central control host 2 are loop-connected. The power supply detection box 3 supplies power to the central control host 2 through the power supply slot 203, so that the central control host 2 is turned on, and the engineering mode trigger push rod 9 is pressed on the engineering mode trigger button. After the central control host 2 is turned on, it directly enters the audio test of the engineering mode.

[0041] When the power supply detection box 3 is plugged into the central control host 2, the electromagnet module 502 is powered on to generate magnetic force, attracting the central control host 2, and the telescopic control part 501 retracts to pull the central control host 2 back to the initial position. The electromagnet module 502 is powered off, the telescopic control part 501 further retracts, and the conveyor belt 1 starts to transport for the next cycle.

[0042] The worker checks the central control host 2 on the conveyor belt 1 that has been turned on and tested downstream of the conveyor belt 1 , and unplugs the power supply detection box 3 ; the power supply detection box 3 is collected and reloaded into the buffer bucket 401 .

[0043] When loading the power supply detection box 3, the push cylinder 406 first controls the push cylinder shaft 407 to contract, so that the push spring 409 retracts and moves. At this time, the power supply detection box 3 is stacked at the end of the push spring 409 and located in the buffer slot 401. The push cylinder 406 extends again and squeezes the power supply detection box 3 through the push spring 409, so that the power supply detection box 3 is close to each other; at this time, the charging contact rod 410 and the charging contact sheet 411 cooperate to charge the power supply detection box 3 at the end.

[0044] During the above process, when the push cylinder 406 controls the push cylinder shaft 407 to contract, the spring support plate 408 will press on the synchronous control plate 419, so that the synchronous control plate 419 is pushed, and the synchronous control plate 419 drives the connecting plate 416 to move through the connecting shaft 418, so that the tension spring 417 is stretched, and the tension spring 417 accumulates force at this time; after the power supply detection box 3 is loaded, the distance sensor 428 detects that the distance from the newly loaded power supply detection box 3 to the distance sensor 428 is shortened, and the electromagnetic valve 423 is controlled to open for a period of time and then closed. At this time, the negative pressure pipe 414 performs negative pressure suction on the bottom cavity 424 of the trough bucket through the negative pressure control pipe 422, so that the bottom hole 425 quickly inhales air, and removes the dust adhered to the power supply detection box 3 due to the transfer, thereby improving the cleanliness of the production line; when the push cylinder 406 is extended again, under the elastic force of the reset spring 420, the synchronous control plate 419 resets and moves, so that the split piston 415 resets.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
