conveyor belts

12 and 22 of the first and

second conveyors

10 and 20 and the conveyor belt 541 of the machine 50 rotate. A workpiece to be tested, such as an opened notebook computer 90, mounted on the base 100 is placed on the conveyor belt 12 of the first conveyor 10, and the base 100 and the notebook computer 90 move to the right along with the first conveyor 10 and are guided by the guide 14 to move to the right end of the first conveyor 10. When the fourth sensor 16 senses the notebook computer 90, the control system 51 detects whether the first sensor 555, the second sensor 556 and the third sensor 557 are triggered: if the first sensor 555, the second sensor 556 and the third sensor 557 are not triggered, the control system 51 controls the cylinder 43 to pull the stop plate 41 downward below the conveyor belt 12 and the conveyor belts 541, and if the base 100 and the notebook computer 90 move from the conveyor belt 12 to the right on the two conveyor belts 541, the control system 51 does not drive the cylinder 43 and the stop plate 41 stops the base 100 on the first conveyor 10 if the first sensor 555, the second sensor 556 or the third sensor 557 are triggered, which indicates that a workpiece is to be detected on the machine 50.

When the base 100 and the notebook computer 90 move to the right along with the conveyor 541 to the vicinity of the first sensor 555 to trigger the first sensor 555, the base 100 is located right above the supporting board 5536.

Meanwhile, the control system 51 controls the first transmission member 551 to drive the carrier 553 to move rightward, and controls the double-row belt wheel conveyor 54 to stop working.

When the carrier 553 moves to the vicinity of the second sensor 556 to trigger the second sensor 556, the control system 51 controls the air cylinder 43 to lift the stop plate 41 above the conveyor belt 12 and the conveyor belt 541, the control system 51 reads the product serial number of the notebook computer 90 through the barcode sensor 79, and the shock detection module 77 detects whether the fixing frame 73 is below a limited shock wave: if the vibration wave is not below the limited vibration wave, the laser 3D scanning camera 75 is not started, the warning lamp 200 is on, the operator can press the reset button, the bearing member 553 returns to the vicinity of the second sensor 556, the operator presses the switch button again after adjusting the fixing frame 73, and the vibration detection module 77 performs detection again; if the vibration wave is below the limit, the control system 51 starts the laser 3D scanning camera 75, the laser 3D scanning camera 75 starts to scan the keyboard of the notebook computer 90, measures the gap between the height of the key 91 and the key 91, and the supporting member 553 continues to move rightward, when the supporting member 553 moves to the vicinity of the third sensor 557 to trigger the third sensor 557, the laser 3D scanning camera 75 scans a half area of the keyboard of the notebook computer 90, the control system 51 temporarily closes the laser 3D scanning camera 75, and controls the first transmission member 551 to drive the supporting member 553 to move leftward to return to the vicinity of the second sensor 556, and simultaneously, the control system 51 controls the second transmission member 71 to drive the laser 3D scanning camera 75 to move to the other end of the second transmission member 71. When the second sensor 556 is triggered again, the control system 51 restarts the laser 3D scanning camera 75, the laser 3D scanning camera 75 starts to scan the other half of the keyboard of the notebook computer 90, and the carrier 553 continues to move rightward, when the carrier 553 moves to the vicinity of the third sensor 557 again to trigger the third sensor 557, the keyboard of the notebook computer 90 is completely scanned, the laser 3D scanning camera 75 transmits the measurement data to the control system 51, the control system 51 compares the measurement data with the tolerance data in the database, and transmits and displays the scanning comparison result on the display 80. The control system 51 temporarily turns off the laser 3D scanning camera 75 and controls the first transmission member 551 to drive the carrier 553 to move left and return to the vicinity of the first sensor 555. If the control system 51 determines that the detection result is qualified, the control system 51 controls the double-row belt wheel conveyor 54 to continue to work, and controls the cylinder 5534 to lower the bearing plate 5536 to a position below the position between the two conveyor belts 541, and the base 100 and the notebook computer 90 are supported on the two conveyor belts 541 and move to the right along with the two conveyor belts 541 on the second conveyor 20; if the control system 51 determines that the detection result is not qualified, the warning light 200 is turned on, and the operator can take out the unqualified notebook computer 90 together with the base 100. And then, detecting the next workpiece to be detected.
