A first linear movement driver 4 is provided on the workbench 1. A mobile phone holder is provided on the execution end of the first linear movement driver 4. One end of the movement path of the first linear movement driver 4 driving the mobile phone holder reaches the edge of the workbench 1, and the other end of the movement path of the first linear movement driver 4 driving the mobile phone holder is in the center of the workbench 1. A second linear movement driver 5 is provided above the first linear movement driver 4 on the workbench 1 through a bracket 2. The projection of the movement path of the second linear movement driver 5 driving an object on the workbench 1 intersects between the two ends of the projection of the movement path of the first linear movement driver 4 driving the mobile phone holder on the workbench 1. An industrial camera 3 is provided on the execution end of the second linear movement driver 5 through a lifting device. The industrial camera 3 is signal-connected to the PLC single-chip microcomputer. The PLC single-chip microcomputer is signal-connected to the first linear movement driver 4 and the second linear movement driver 5. A sensor is provided on the mobile phone holder, and the sensor is signal-connected to the PLC single-chip microcomputer.

[0025] In this embodiment, during use, the folding screen mobile phone is placed on the mobile phone holder, and then the first linear motion driver 4 moves the mobile phone holder to the center of the workbench 1. After that, the second linear motion driver 5 drives the industrial camera 3 to take a picture of the folding screen mobile phone located on the mobile phone holder directly above. Then, the information of the taken picture is transmitted to the PLC single-chip microcomputer to determine whether the product size is qualified. After that, the PLC single-chip microcomputer conveys the judged folding screen mobile phone to the edge of the workbench 1 through the first linear driver 4 and the mobile phone holder, facilitating the worker to pick it up. Preferably, it further includes a display screen, and the display screen is signal-connected to the PLC single-chip microcomputer, so that the PLC single-chip microcomputer transmits the detected result to the display screen for the worker to view. During the whole process, the worker only needs to place the folding screen mobile phone on the mobile phone holder for fixation.

[0026] As a preferred way, both the first linear motion driver 4 and the second linear motion driver 5 are linear motors. In this way, the linear driving function can be realized through the linear motor.

The product placement opening 10 is located on the side wall of the housing 9 corresponding to the edge of the workbench 1 that the first linear motion driver 4 can reach when driving the mobile phone holder to move. After setting the housing 9, dust is prevented from floating onto the workbench 1. At the same time, it can also play a safety role to prevent the worker from touching the mobile phone holder during the detection of the folding screen mobile phone.

[0029] As a preferred way, a light source 11 that cooperates with the industrial camera 3 is further provided on the slider 8 below the industrial camera 3. After such a setting, the light source 11 can provide light for the industrial camera 3 inside the housing 9.

By setting the grating 12 in this way, it is avoided that the worker's hand reaches into the housing 9 before the folding screen mobile phone is detected. In actual application, if the grating 12 recognizes that the worker reaches their hand into the housing 9, the PLC single-chip microcomputer will cause the industrial camera 3, the first linear movement driver 4, the second linear movement driver 5, and the lifting device to stop working.

[0031] As a preferred method, an indicator light 13 is provided on the outer wall of the housing 9, and the indicator light 13 is signal-connected to the PLC single-chip microcomputer.
