It can be understood that when a plurality of manipulators 40 are provided, each manipulator 40 corresponds to one detection unit 31, so that the detection work can be simultaneously performed by the plurality of detection units 31, and the detection efficiency can be improved.

In this embodiment, a plurality of sub-conveying rails 111 are arranged at intervals, each sub-conveying rail 111 is provided with a material loading tray 12, the material loading tray 12 reciprocates on the sub-conveying rail 111, the material loading tray 12 is used for loading mobile phone PCB boards qualified for detection and is conveyed to a position close to the next sub-conveying rail 111 on the sub-conveying rail 111, then the manipulator 40 on the next sub-conveying rail 111 captures the mobile phone PCB boards on the material loading tray 12 and puts the mobile phone PCB boards to the detection unit 31 corresponding to the manipulator 40 for detection, after the detection is completed, the manipulator 40 captures the qualified mobile phone PCB boards into the material loading tray 12 on the sub-conveying rail 111 and conveys the mobile phone PCB boards to a position close to the next sub-conveying rail 111 on the sub-conveying rail 111, and the steps are repeated until all the detections are completed. Therefore, the material loading discs 12 can be repeatedly used on the sub-conveying tracks 111, the number of the material loading discs 12 can be reduced, the structure of the mobile phone PCB automatic testing equipment is simplified, and the cost is reduced.

In this embodiment, the base 10 is provided with a temporary storage location 70 near the sub-conveying track 111, and the temporary storage location 70 is used for placing an unqualified mobile phone PCB to be detected. It can be understood that, when the mobile phone PCB is detected in the detection unit 31, the mobile phone PCB which is detected to be unqualified does not need to be placed on the material loading tray 12 to be transmitted to the next detection unit 31 for detection. In the unqualified mobile phone PCB, a detection error may exist, that is, the qualified mobile phone PCB is detected as an unqualified mobile phone PCB, so that the mobile phone PCB needs to be detected for many times to reduce the detection error, wherein the temporary storage position 70 may be disposed at one end of the sub-conveying track 111 or at one side of the sub-conveying track 111. In this embodiment, by setting the cache position on the base 10, the mobile phone PCB that is unqualified to be detected can be grabbed by the manipulator 40 and placed in the cache position, and after the unqualified mobile phone PCBs in the cache position accumulate a certain number, the manipulator 40 grabs the unqualified mobile phone PCBs of the part to be detected again.

Specifically, one end of the defective discharge device 80 is close to the temporary storage position 70, the other end is located between two adjacent detection units 31, and the conveying direction of the defective discharge device 80 is a direction away from the temporary storage position 70. It can be understood that the mobile phone PCB which is unqualified after being detected for many times is determined to have defects, the detection through the subsequent detection unit 31 is not needed, and the defective mobile phone PCB can be sent out by arranging the defective product discharging device 80. Therefore, automation can be realized, and the detection efficiency is improved. The defective product discharging device 80 can be used for sending out the mobile phone PCB which is detected to be unqualified for the first time, sending out the mobile phone PCB which is detected to be unqualified for the second time, and the like.

Specifically, the vacuum chuck 432 on the first supporting rod grabs the mobile phone PCB to be detected, the mechanical arm 42 drives the suction head assembly 43 to move into the detection unit 31, the second mounting plate arm grabs the mobile phone PCB after detection, and then the support 431 is rotated to place the mobile phone PCB to be detected on the first supporting rod into the detection unit 31 for detection.

If unqualified mobile phone PCBs exist in the mobile phone PCBs detected on the second support rod, the suction head assembly is moved to a temporary storage area, the unqualified mobile phone PCBs are placed in the temporary storage area, and then the qualified mobile phone PCBs are placed in the material carrying tray 12 on the sub-conveying track 111. When the unqualified mobile phone PCB in the temporary storage area is fully loaded, the suction head assembly 43 is used for grabbing the mobile phone PCB for detection again. The mobile phone PCB which is detected for a plurality of times and is unqualified is put to a defective product discharging device 80 by the manipulator 40 and is sent out. After the material loading tray 12 on the sub-conveying track 111 is filled with qualified mobile phone PCBs, the material loading tray 12 is conveyed on the sub-conveying track 111 toward the next sub-conveying track 111, and the manipulator 40 of the next sub-conveying track 111 grips the mobile phone PCBs on the material loading tray 12 for detection, and the detection processes on each sub-conveying track 111 are the same, which is not described herein again. And (3) until the mobile phone PCB is detected on the last sub-conveying track 111 and is conveyed to the discharging device 90, and then the qualified PCB is manually taken out from the discharging device 90, so that the detection is completed.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
