[0027] Example

[0028] See Figures 1 to 10 As shown in the figure, a fixture system for testing PCBA is proposed according to an embodiment of the present invention. The fixture system includes: a load voltage detection module, a static current detection module, a charging current detection module, a buzzer drive module, an air pump drive module, a digital four-digit display module, and an MCU control unit. The load voltage detection module, the static current detection module, and the charging current detection module are all connected to the MCU control unit, and the buzzer drive module, the air pump drive module, and the digital four-digit display module are all connected to the MCU control unit.

[0029] In one embodiment, the digital driving four-digit display module includes a driver chip, which is an AiP650 series chip and includes an SCL pin and an SDA pin. The SCL pin is connected to the first end of diode D7, and the second end of diode D7 is connected to a first resistor R13 and the CLK pin of the driver chip. The first resistor R13 is also connected to the DC power input terminal DCIN. The SDA pin is connected to the first end of diode D8, and the second end of diode D8 is connected to a second resistor R31 and the DAT pin of the driver chip. The second resistor R31 is also connected to the DC power input terminal DCIN.

[0030] In one embodiment, the driver chip is an AiP650E0 chip, which includes four DIG chip pins. Each of the four DIG chip pins is connected to an independent display bit pin group of the digital display tube, including DIG1 digital pin, DIG2 digital pin, DIG3 digital pin, and DIG4 digital pin. The segment selection control pin group of the digital display tube is connected to multiple chip pins of the driver chip.

[0031] In one embodiment, the segment selection control pin group of the digital display tube includes seven DS digital pins and one DS-DP digital pin. The seven DS digital pins are respectively connected to the seven KI chip pins of the driver chip, and the DS-DP digital pin is connected to the KP chip pin of the driver chip.

[0032] In one embodiment, the fixture system further includes a Type-C module and an LDO module, wherein the Type-C module is connected to the driver chip via the LDO module; the load voltage detection module, the static current detection module, and the charging current detection module are all connected to the Type-C module; and the buzzer driver module, the air pump driver module, and the digital driver four-digit display module are all connected to the Type-C module.

[0033] Secondly, this application proposes an electronic cigarette testing system, which includes an electronic cigarette simulated air pump and a fixture system for testing PCBA as described in the first aspect, wherein the air pump drive module of the fixture system is connected to the electronic cigarette simulated air pump.

[0034] This application addresses many shortcomings of traditional fixtures. Its working principle is as follows: First, a single digital tube on the display interface sequentially displays current and voltage parameters. Software collects the current and voltage parameters on the PCBA under test and compares them with preset values ​​to automatically determine whether they are qualified. If qualified, the corresponding qualified parameters are displayed; otherwise, an "Er" error is displayed, and a buzzer continuously sounds as a reminder, greatly saving costs, avoiding the possibility of misjudgment, and improving efficiency. Second, it automatically recognizes when the PCBA under test is pressed down (the operation interface is omitted). After recognition, testing can begin. Through relay switching on the test board, each process automatically switches according to the flow, testing and outputting a qualification / failure conclusion. Third, it can test multiple PCBAs simultaneously, significantly improving efficiency, saving manpower, and reducing mistesting.

[0035] In summary, the PCBA (Printed Circuit Board Assembly) testing of e-cigarettes is necessary in laboratory simulation testing. This testing provides quantifiable and repeatable experimental support for the product's reliability, consistency, and compliance. PCBA testing ensures that the R&D and production of e-cigarettes meet relevant standards and improves the consumer experience. However, existing PCBA testing solutions have the following shortcomings: First, each ammeter or voltmeter can only display one parameter, and parameter qualification is prone to misjudgment; second, the test interface is cumbersome, and manual operation is prone to errors; third, PCBAs can only be tested one at a time, resulting in low overall efficiency.
