[0032] A cavity 32 is provided in the lower transmission seat 25, and the cavity 32 is communicated with the rotating groove 27 in the lower transmission seat 25.

A lower support rod 37 is fixed to the lower end of the magnifying glass 19, and the lower support rod 37 can pass through the lower through groove 35 and the opening 31 to extend into the rotating sleeve 29, and an upper support rod 38 is fixed to the upper end of the magnifying glass 19, and the upper support rod 38 can pass through the upper through groove 36 and the opening 31 to extend into the rotating sleeve 29. A limiting groove 39 is provided in the upper transmission seat 26, and the limiting groove 39 is communicated with the rotation groove 27 in the upper transmission seat 26, and the upper through groove 36 is communicated with the limiting groove 39.

The width of the limiting rod 41 is smaller than the width of the upper through groove 36, and the length is greater than the width of the upper through groove 36, and the length of the limiting rod 41 is greater than the width of the communication hole between the limiting groove 39 and the rotation groove 27.

[0033] It also includes a controller and an alarm. The controller is used to control the alarm, cylinder 7, laser transmitter 17, laser receiver 18, electromagnetic plate, motor 33, screw transmission mechanism 1 12, screw transmission mechanism 2 21, and screw transmission mechanism 3 22.

[0034] Working principle: Place the laptop shell on the upper end of the support plate 3, adjust the height of the moving block 16 according to the thickness of the notebook, so that the laser emitted by the laser transmitter 17 just fits with the upper end surface of the shell, and the laser receiver 18 can successfully receive the laser signal emitted by the laser transmitter 17. Start the screw transmission mechanism 12, the screw transmission mechanism 12 drives the moving platform 11 to move, so that the laser emitted by the laser transmitter 17 sweeps across the upper end surface of the entire shell. When the upper end surface of the shell is splashed with paint liquid, the paint liquid forms a small bulge, so the laser receiver 18 cannot successfully receive the laser emitted by the laser transmitter 17, and the laser receiver 18 sends a signal to the controller, the controller commands the alarm to work, and the alarm notifies the staff.

[0035] After the detection of the upper end face of the outer shell is completed, the cylinder 7 is started. The cylinder 7 drives the ejector rod 9 and the top plate 5 to move upward. The top plate 5 passes through the through hole 4 to lift the outer shell, so that the outer shell rises above the surrounding plate 2. The initial position of the magnifying glass 19 is located in the rotating sleeve 29 in the lower transmission seat 25, and the opening 31 of the rotating sleeve 29 is offset from the position of the lower through groove 35. The electromagnetic plate in the lower transmission seat 25 is energized to fix the rotating sleeve 29 and the lower transmission seat 25, preventing the magnifying glass 19 from rotating randomly. The screw drive mechanism II 21 is started. The screw drive mechanism II 21 drives the slider II 23 and the lower transmission seat 25 to move, so that the magnifying glass 19 moves along the side of the outer shell, facilitating the staff to observe the side of the outer shell.

[0036] When the lower transmission seat 25 approaches the upper transmission seat 26, the upper support rod 38 and the limit rod 41 pass through the upper through groove 36 and the opening 31 of the rotating sleeve 29 in the upper transmission seat 26 and extend into the rotating sleeve 29 and the limit groove 39 in the upper transmission seat 26. When the lower transmission seat 25 is completely below the upper transmission seat 26, the upper support rod 38 is completely clamped into the rotating sleeve 29 in the upper transmission seat 26. Then the motor 33 is started. The motor 33 drives the fixed plate 34 and the rotating sleeve 29 in the lower transmission seat 25 to rotate 90°, so that the opening 31 of the rotating sleeve 29 in the lower transmission seat 25 coincides with the position of the lower through groove 35, that is, at this time the lower support rod 37 can move out of the lower transmission seat 25 from the opening 31 and the lower through groove 35; at the same time, the motor 33 drives the magnifying glass 19 to rotate, so that the magnifying glass 19 is parallel to the other side of the outer shell, facilitating detection. At the same time, the upper support rod 38 drives the rotating sleeve 29 and the limit rod 41 in the upper transmission seat 26 to rotate. The opening 31 of the rotating sleeve 29 in the upper transmission seat 26 is offset from the position of the upper through groove 36, so as to prevent the upper support rod 38 from falling along the upper through groove 36 from the opening 31, and the limit plate is perpendicular to the upper through groove 36 after rotation, so as to prevent the upper support rod 38 from falling under the action of gravity. Then the electromagnetic plate in the upper transmission seat 26 is energized, and the rotating sleeve 29 in the upper transmission seat 26 is fixed to the upper transmission seat 26. The screw drive mechanism III 22 is started. The screw drive mechanism III 22 drives the slider III 24 and the magnifying glass 19 to move, so that the lower support rod 37 moves out of the lower transmission seat 25 along the opening 31 and the lower through groove 35, and the magnifying glass 19 detects along the second side of the outer shell.

[0037] When the upper driving seat 26 moves to another lower driving seat 25, the lower support rod 37 enters the rotating sleeve 29 along the lower through groove 35 and the opening 31 of the lower driving seat 25. When the lower support rod 37 completely enters the rotating sleeve 29 inside the lower driving seat 25, the electromagnetic plates inside the upper driving seat 26 and the lower driving seat 25 are electrified, so that the upper driving seat 26 and the rotating sleeve 29, and the lower driving seat 25 and the rotating sleeve 29 are no longer fixed. The motor 33 inside the lower driving seat 25 at this position is started, and the motor 33 drives the rotating sleeve 29 and the lower support rod 37 inside the lower driving seat 25 to rotate, so that the opening 31 of the rotating sleeve 29 inside the lower driving seat 25 is misaligned with the lower through groove 35. At the same time, the upper support rod 38 and the limiting rod 41 rotate, so that the opening 31 of the rotating sleeve 29 inside the upper driving seat 26 coincides with the upper through groove 36, and the limiting rod 41 is placed parallel to the upper through groove 36. At this time, the magnifying glass 19 also rotates 90° and is arranged parallel to the third side. Then the electromagnetic plates inside the upper driving seat 26 and the lower driving seat 25 are electrified, and the second lead screw transmission mechanism 21 is started. The second lead screw transmission mechanism 21 drives the second slider 23 to move with the lower driving seat 25, so that the upper support rod 38 and the limiting plate pass through the opening 31 and the upper through groove 36 and move out of the upper driving seat 26. The detection principle of using the magnifying glass 19 for other sides of the shell is the same as above.

[0038] The above content is only an example and description of the structure of the present invention. Those skilled in the art of this technology make various modifications or supplements to the described specific embodiments or use similar methods for substitution. As long as they do not deviate from the structure of the present invention or exceed the scope defined by this claim book, they should all belong to the protection scope of the present invention.
