[0022] During the specific test, the plug-in fixture is installed on one side of the mobile phone test equipment, and the mobile phone to be tested is installed on the installation fixture; by controlling the operation of the driving component, the installation component can be driven to move in the direction close to the mobile phone test equipment, and the installation component drives the test circuit board 2 to move synchronously, and the test circuit board 2 will be inserted into the SIM card slot of the mobile phone on the installation fixture; then the operator can judge whether the SIM card slot of the mobile phone is normal through the mobile phone test equipment. After the test is completed, the driving component is controlled to drive the installation component to move in the direction away from the mobile phone test equipment, and the installation component drives the test circuit board 2 to move synchronously, so as to pull the test circuit board 2 out of the SIM card slot of the mobile phone. Through the plug-in fixture, the test circuit board 2 can be automatically inserted into the mobile phone on the installation fixture, and can be automatically pulled out. Using machines instead of manual labor can reduce labor costs; and by controlling the driving stroke of the driving component, the insertion stroke can be accurately controlled, thereby ensuring that the force of each insertion is consistent, avoiding the problem of inaccurate testing due to inconsistent insertion force, and improving the accuracy of the test.

[0023] The driving assembly includes a driving motor 3, which is electrically connected to the controller. The driving motor 3 is fixedly mounted on the fixing seat 1, and a driving screw 4 is provided on the output end of the driving motor 3, and a driving slider 5 is sleeved on the driving screw 4, and the driving slider 5 is fixedly connected to the mounting assembly; when the test circuit board 2 needs to be plugged in and out, the driving motor 3 is controlled to work, and the driving screw 4 can be driven to rotate, and the driving screw 4 drives the driving slider 5 to slide on the driving screw 4, and the driving slider 5 drives the mounting assembly and the test circuit board 2 to move synchronously, so that the test circuit board 2 moves in a direction close to or away from the mobile phone test device, thereby inserting or pulling out the test circuit board 2 into or out of the SIM card slot of the mobile phone.

[0024] The mounting assembly includes a sliding seat 6, which is fixedly connected to the driving slider 5, a mounting seat 7 is fixedly mounted on the sliding seat 6, a limiting block 8 is arranged on the mounting seat 7, and the test circuit board 2 is fixedly mounted on the limiting block 8; during the test, the driving motor 3 drives the driving slider 5 to move, thereby driving the sliding seat 6, the mounting seat 7, the limiting block 8 and the test circuit board 2 to move synchronously, so as to realize the process of plugging and unplugging the test circuit board 2. The limiting block 8 is connected to the mounting seat 7 in a floating manner, so that the test circuit board 2 can float on the mounting seat 7; so that the test circuit board 2 can achieve soft contact during the process of plugging and unplugging the SIM card slot on the mobile phone, ensuring that the test circuit board 2 can be smoothly inserted into the SIM card slot; preventing the test circuit board 2 or the mobile phone from being damaged due to displacement of the test circuit board 2 or the mobile phone, thereby improving the processing yield rate.

[0028] A pressure sensor 13 is installed on the sliding seat 6, and the pressure sensor 13 is connected to the driving slider 5. The pressure sensor 13 is electrically connected to the controller. The pressure sensor 13 is used to detect the pressure value of the test circuit board 2 inserted into the SIM card slot, thereby improving the accuracy of the test control. When the driving motor 3 drives the test circuit board 2 to be inserted into the SIM card slot of the mobile phone, the driving slider 5 drives the sliding seat 6 to move, and the sliding seat 6 can drive the pressure sensor 13 to move synchronously. When the test circuit board 2 is inserted into the extreme position of the SIM card slot, a reaction force will be transmitted to the pressure sensor 13, so that the pressure data of the test circuit board 2 inserted into the SIM card slot is detected by the pressure sensor 13, so that the controller can realize accurate control of the test process.

[0029] In order to limit the stroke of the test circuit board 2 inserted into or removed from the SIM card slot, a sensing paddle 14 is provided on the mounting seat 7, and two stroke sensors 15 are provided on the fixing seat 1. The stroke sensors 15 are electrically connected to the controller respectively, and the sensing paddle 14 can be connected to the two stroke sensors 15 respectively. In the initial state, the sensing paddle 14 is connected to one of the stroke sensors 15; in the process of the driving motor 3 driving the test circuit board 2 to be inserted into the SIM card slot of the mobile phone, the sensing paddle 14 will be connected to the other stroke sensor 15; when the sensing paddle 14 is connected to the other stroke sensor 15, the stroke sensor 15 will feedback a signal to the controller, and the controller will immediately control the driving motor 3 to stop working, indicating that the test circuit board 2 has been inserted into the SIM card slot of the mobile phone. After the test is completed, the driving motor 3 drives the test circuit board 2 to pull out the SIM card slot of the mobile phone until the sensing paddle 14 is connected to the stroke sensor 15 in the initial state, and then feedbacks a signal to the controller, and the controller controls the driving motor 3 to stop working, indicating that the test circuit board 2 has been reset to the initial position at this time.

[0033] After the test is completed, the drive motor 3 is controlled to work, driving the drive screw 4 to rotate in the opposite direction, thereby driving the drive slider 5 to slide on the drive screw 4, and the drive slider 5 drives the sliding seat 6, the mounting seat 7, the limit block 8 and the test circuit board 2 to move together, so that the test circuit board 2 is pulled out of the SIM card slot of the mobile phone; until the induction paddle 14 is connected with the stroke sensor 15 in the initial state, the feedback signal controls the drive motor 3 to stop working, indicating that the test circuit board 2 has been pulled out of the SIM card slot of the mobile phone and reset to the initial position.
