[0027] This utility model proposes a foolproof controller, which aims to control the power supply of the scanner by the main control board according to the test result signal of the product, and to prompt the operator through the voice playback component, so as to effectively prevent the risk of missed or unqualified products from being released, thus achieving effective foolproof and error prevention.

[0028] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the foolproof controller 10 includes:

[0029] Housing 1, wherein a receiving cavity 11 is formed inside the housing 1;

[0030] Main control board 2, which is disposed in the receiving cavity 11, and is electrically connected to the scanning gun and the electrical measuring machine;

[0031] A voice playback component 3 is installed inside the receiving cavity 11 and located on one side of the main control board 2. The main control board 2 is electrically connected to the voice playback component 3 to control the voice playback component 3 to emit prompt sounds.

[0032] In this embodiment, the foolproof controller 10 includes a housing 1, a main control board 2, and a voice playback component 3. A receiving cavity 11 is formed within the housing 1. The main control board 2 is disposed within the receiving cavity 11 and is electrically connected to the barcode scanner. The main control board 2 receives test signal results from the previous workstation. If the electrical test is successful, the main control board 2 receives an OK signal from the electrical testing machine, controls the barcode scanner to power on, and emits a prompt sound through the voice playback module 31 to remind the operator to scan the product's barcode. After scanning is complete, the voice playback module 31 emits another prompt sound to remind the operator to scan the product's barcode. Once the product's barcode is scanned, it effectively prevents the situation where the product's barcode is not scanned. At the same time, the main control board 2 also receives the signal that the barcode scanning is complete. The main control board 2 then controls the scanner to power off again. If the product fails the electrical test or has not been tested, the main control board 2 will not control the scanner to power on or control the voice playback module 31 to produce a prompt sound when it receives an NG signal or no signal from the electrical tester. This effectively intercepts products that fail the electrical test or have not been tested, avoiding the risk of untested or unqualified products being released, thus achieving effective error prevention.

[0033] In one embodiment, please refer to Figure 2 The foolproof controller 10 also includes a barcode signal transmitter 4, which is installed in the receiving cavity 11 and spaced apart from the main control board 2. The main control board 2 is electrically connected to the barcode signal transmitter 4, and the barcode signal transmitter 4 is electrically connected to the scanner.

The barcode signal transmitter 4 is installed in the receiving cavity 11 and is spaced apart from the main control board 2. The main control board 2 is electrically connected to the barcode signal transmitter 4, and the barcode signal transmitter 4 is electrically connected to the barcode scanner. After the barcode scanner completes scanning, the barcode signal transmitter 4 transmits the scanned signal to the main control board 2. The main control board 2 disconnects the barcode scanner from communication until the next time the electrical tester sends an OK signal.

[0035] It should be noted that the barcode signal transmitter 4 is a common signal transmitter, and this application does not limit it.

[0036] In one embodiment, please refer to Figure 2 The foolproof controller 10 also includes an adapter board 5, which is installed in the receiving cavity 11.

The voice prompt component 32 is located on the inner wall of the receiving cavity 11 and covers the sound outlet hole. The voice playback module 31 is electrically connected to the voice prompt component 32.

[0039] In this embodiment, the voice playback component 3 includes a voice playback module 31 and a voice prompt component 32. The voice playback module 31 is installed in the receiving cavity 11 and spaced apart from the main control board 2. The main control board 2 is electrically connected to the voice playback module 31. One side of the housing 1 has a sound outlet hole that connects to the outside and the receiving cavity 11. The voice prompt component 32 is located on the inner wall of the receiving cavity 11 and covers the sound outlet hole. Therefore, the sound generated by the voice prompt component 32 is transmitted to the outside through the sound outlet hole. The voice playback module 31 is electrically connected to the voice prompt component 32. Therefore, after receiving the test OK signal from the electrical testing machine, the main control board 2 controls the barcode scanner to be powered on and emits a prompt sound through the voice playback module 31 to prompt the operator to scan the product barcode. After scanning is completed, the voice playback module 31 emits a prompt sound again to prompt the operator that the product barcode scanning is complete, effectively avoiding the situation where the product barcode is not scanned.
