The first sensor 3021 or the second sensor 3031 is In order to sense whether the carrier 31 is in the identification position 302 or the grabbing position 303, the discharge position 301 is used to put a piece to be tested 300 into the carrier 31 (in this embodiment , the test piece 300 is a mobile phone, and the mobile phone includes an area to be identified 200) with an area printed with an IMEI number, and the character recognition element 20 is set above the identification position 302, so that the image acquisition unit 21 is facing the area 200 of the piece to be tested 300 to be identified. The grabbing position 303 is used to grab the piece to be tested 300 and enter the next test unit 400. The test unit 400 is used to plug in the piece to be tested. The test piece 300 obtains the IMEI number stored in the piece to be tested 300 and determines whether the IMEI number is the same as the character information stored in the storage unit 23 . Wherein, the first sensor 3021 and the second sensor 3031 may be position sensors. During specific work, the operator loads a piece to be tested 300 into the carrier 31 at the loading position 301, and the processing unit 22 issues an actuation command of the drive motor 242, so that the piece to be tested is loaded into the carrier 31. The carrier 31 of the component 300 starts to move from the discharge position 301 until the first sensor 3021 senses that the carrier 31 moves to the identification position 302, and the processing unit 22 sends out the After the stop command of the driving motor 242, the carrier 31 stays at the identification position 302, and waits for the character recognition element 20 to complete the recognition of the character information of the to-be-recognized area 200 of the test piece 300. and stored, the processing unit 22 again An actuation instruction for the driving motor 242 is given until the second sensor 3031 senses that the carrier 31 moves to the grabbing position 303, and the processing unit 22 issues a stop instruction for the driving motor 242 again. The carrier 31 stays in the grabbing position 303, and when the test piece 300 in the carrier 31 enters the next test unit 400, the processing unit 22 sends out the signal of the drive motor 242. The actuation command causes the carrier 31 to return to the discharge position 301 . When the processing unit 22 senses that the identification bit 302 or the capture bit 303 is faulty (for example, the processing unit 22 determines that the character information on the identification bit 302 is incorrect), so The processing unit 22 gives an actuation instruction to the drive motor 242 so that the carrier 31 carrying the piece to be tested 300 returns to the discharge position 301, and the operator further confirms.
