At this time, the motor drives the slider 213 to move inside the slide groove 212, and the slider 213 drives the limit block 214 to move on the fixed block 211 until the limit block 214 moves to the top of the round rod 112 and stops, and then the electric telescopic rod 232 is started, and the electric telescopic rod 232 is electrically retracted. The rod 232 generates a thrust on the connecting rod 241. Because the electric telescopic rod 232 is connected to the connecting rod 241 through a rotating shaft, when the thrust reaches a certain level, the placement plate 11 is propped up by rotating the universal shaft. At this time, the placement plate 11 and the workbench 10 form a certain angle. When it reaches a suitable position, it stops. At this time, the clamping block 14 in the inclined direction moves toward the top of the workbench 10. The structure to be inspected moves on the placement plate 11 with the clamping block 14 due to the inclined surface. When the clamping block 14 reaches the limit position, it stops. At this time, the clamping block The protrusions on both sides of 14 move into the fixed grooves of the side walls of the slider three 1212, and then the slider three 1212 is driven by the motor to move in the direction of the bottom wall of the embedding groove 131 inside the slide groove three 1211, driving the clamping block 14 and the column rod 133 to squeeze the spring 132 until the clamping block 14 is completely embedded in the top of the workbench 10 and stops. At this time, the detected part moves from the top of the workbench 10 to the conveying mechanism, and then the slider three 1212 returns to its original position. At this time, the elastic force of the spring 132 is restored, and the clamping block 14 returns to its original position The placement plate 11 is also restored to its original position, and the next laptop computer structure is continued to be inspected. When the inspected part has a problem, the parts with appearance problems are uniformly transported in one direction to facilitate the recycling work. When the round rod 112 on one side of the bottom of the placement plate 11 is limited, the placement plate 11 can be lifted in four directions through the cooperation of the universal joint, the connecting rod 241 and the electric telescopic rod 232. This makes it convenient to uniformly inspect and classify the laptop computer structures, thereby speeding up the inspection efficiency of the laptop computer structures.

[0027] The working principle of the present invention is: The electrical components in the present invention are all triggered to operate by a PLC controller.

[0028] First, the notebook structure is placed in the middle of the placement plate 11 through the conveying mechanism. At this time, four conveying mechanisms are respectively provided on the four sides of the equipment, one of which is for returning the problematic parts. When there is a notebook computer structure on the placement plate 11, the slider 122 is driven by the motor to move inside the slide groove 121, and the slider 122 drives the clamping block 14 to clamp according to the size of the inspection part, and then the appearance inspection mechanism is started. The appearance inspection mechanism sends the picture of the inspected part to the PLC controller, and the PLC controller compares the pictures and then inspects them one by one. After the inspection is completed, the inspected parts are classified by the PLC controller, such as the shell, motherboard and other parts. At this time The round rod 112 at the bottom of the placement plate 11 is placed on the placement circular plate 222, and the limit block 214 on the corresponding classification side is started by detecting data through the PLC controller, and the other limit blocks 214 do not move. At this time, the slider 213 is driven by the motor to move inside the slide groove 212, and the slider 213 drives the limit block 214 to move on the fixed block 211 until the limit block 214 moves to the top of the round rod 112 and stops. Then the electric telescopic rod 232 is started, and the electric telescopic rod 232 generates a thrust on the connecting rod 241. Because the electric telescopic rod 232 is connected to the connecting rod 241 through a rotating shaft, when the thrust reaches a certain level, the placement plate 11 is propped up by rotating the universal shaft. At this time, the placement The plate 11 forms a certain angle with the workbench 10, and stops when it reaches the appropriate position. At this time, the clamping block 14 in the inclined direction moves toward the top of the workbench 10, and the inspected structural part moves on the placement plate 11 along with the clamping block 14 due to the inclined surface. When the clamping block 14 reaches the limit position, it stops. At this time, the protrusions on both sides of the clamping block 14 move into the fixed grooves on the side walls of the slider three 1212, and then the slider three 1212 is driven by the motor to move inside the slide groove three 1211 toward the bottom wall of the embedding groove 131, driving the clamping block 14 and the column rod 133 to squeeze the spring 132, until the clamping block 14 is completely embedded in the top of the workbench 10 and stops. At this time, the inspected structural part Move from the top of the workbench 10 to the conveying mechanism, and then the slider three 1212 returns to its original position. At this time, the elastic force of the spring 132 is restored, the clamping block 14 returns to its original position, and the placement plate 11 also returns to its original position, and continues to inspect the next laptop computer structure. When there is a problem with the inspected part, the parts with appearance problems are uniformly conveyed in one direction to facilitate the recycling work. When the round rod 112 on one side of the bottom of the placement plate 11 is limited, the placement plate 11 can be lifted in four directions through the cooperation of the universal joint, the connecting rod 241 and the electric telescopic rod 232. This makes it convenient to uniformly inspect and then classify the laptop computer structures, thereby speeding up the inspection efficiency of the laptop computer structures.
