The arrow direction in fig. 2 is the width direction of the support carrier 1.
The working principle of the invention comprises the following steps: the display 777 is placed on the support carrier 1, the back faces upwards, the cylinder is started, the cylinder drives the push rod to push the display 777 to move towards the angle, close to the triangular prism, of the support carrier 1, so that the triangular prism can be aligned to a counter bore plug on the side edge of the display 777, then the electric rail 10 is started, the detection camera 12 is enabled to move to conduct characteristic scanning on the counter bore plug on the back face of the display 777, then matching of a computer is conducted, whether a large hole and a small hole of the counter bore are concentric or not can be detected, namely concentricity is detected, when the counter bore characteristic scanning is conducted on the side edge of the display 777, matching is conducted on the detection camera and the triangular prism, detection light sources are enabled to emit detection light sources, the light sources are refracted through the triangular prism by 90 degrees, and accordingly the light sources are reflected on the side edge of a product, after being detected and returned through the light sources, the characteristics (namely counter bore on the side edge) of the side edge of the product can be formed in detection software, and therefore the requirement of sharing one detection camera to detect the side edge of the display screen is achieved.
When the detecting camera 12 moves, the detecting camera 12 moves together with the cleaning device, when the plurality of first meshing teeth 31 on the cleaning device are matched with the rack assembly, the plurality of first meshing teeth 31 are meshed with the second meshing teeth 103 on the rack assembly, and as the second meshing teeth 103 are propped against the blocking plate 104, the plurality of first meshing teeth 31 rotate under meshing, so that the plurality of first meshing teeth 31 rotate for 20 degrees with the rotating ring 29 and the filter screen 30, and the filter screen area where the end of the second air outlet pipe 51, which is positioned in the air inlet pipe 28, is changed;
when the detecting camera 12 moves with the cleaning device, the trapezoid block 26 on the cleaning device is abutted against the first cylindrical rod 90 of the rotating ring, then the trapezoid block 26 moves with the second connecting rod 25, the first connecting rod 24 and the piston block 323 because of the blocking of the first cylindrical rod 90, the spring 324 is extruded by the movement of the piston block 323, the space where the spring 324 is located is reduced, the air pressure is increased, the second one-way valve 34 is opened by the increased air pressure, then air is discharged from the first air outlet pipe 33, dust on the lens at the lower end of the detecting camera 12 is blown off, when the trapezoid block 26 is separated from the first cylindrical rod 90, the piston block 323, the first connecting rod 24, the second connecting rod 25 and the trapezoid block 26 are reset under the action of the spring 324, so that the space where the spring 324 is located is enlarged, the air pressure is reduced, the first one-way valve 35 is opened, and air is sucked into the air inlet pipe 28 from the outside, and then enters the space where the spring 324 is located for storage; when the detecting camera 12 moves with the cleaning device, the first inclined block 70 on the cleaning device can be abutted against the second inclined block 113, the blocking of the second inclined block 113 can enable the first inclined block 70 to move upwards with the moving plate 68, the eighth port 69 is opposite to the sixth port 65, meanwhile, the right end of the moving plate 68 can enable the first air outlet pipe 33 to be close to one end opening of the lens at the lower end of the detecting camera 12 to be plugged (so as to enable larger blowing force to blow out dust on the mirror surface of the triangular prism 5), in this state, as the detecting camera 12 moves with the cleaning device, the trapezoid block 26 can be abutted against the second cylindrical rod 110, then because the blocking of the second cylindrical rod 110 can enable the trapezoid block 26 to move with the piston block 323, the space where the spring 324 is located is reduced again, the air pressure is increased, the increased air pressure can enable the second one-way valve 34 to be opened, and air to be blown out of the eighth port 69, the sixth port 65 and the third air outlet pipe 66 from the position, so that dust on the mirror surface of the triangular prism 5 located below can be cleaned with ease, and the mirror surface can be cleaned with the aid of the detecting camera 12. (when the moving plate 68 is not pushed to move upward, the moving plate 68 will just block the sixth port 65, and the right end of the moving plate 68 will not block the end of the first air outlet pipe 33 near the lower end lens of the inspection camera 12 at this time.)
In order to make clean air better blow dust on the lens at the lower end of the detection camera 12 and dust on the mirror surface of the triangular prism 5, the filter screen 30 is arranged, but after long-term use, too much dust on the filter screen 30 affects the air suction and thus affects the operation of the cleaning device, so when air is discharged through the first air outlet pipe 33, part of air enters the second air outlet pipe 51 and then is blown onto the filter screen from the second air outlet pipe 51, dust in the area, which is opposite to the filter screen, of one end of the second air outlet pipe 51, in the air inlet pipe 28 can be blown off, dust on the filter screen can be removed by part of air while ensuring that enough airflow can blow off dust on the lens at the lower end of the detection camera 12, therefore, dust in the twenty-degree range on the filter screen can be blown off each time, then the first engaging teeth 31 are engaged with the second engaging teeth 103 on the rack assembly, the first engaging teeth 31 are rotated by 20 degrees with the rotating rings 29 and 30, and therefore, the dust in the filter screen can be blown off area, which is opposite to the filter screen can be well blown off, and the dust in the filter screen can be blown off through the filter screen can be blown off by the filter screen at the end of the filter screen at the same time, and the full-time, and the dust can be blown off well when the dust in the area can be blown off through the filter screen at the end of the end.
The embodiments of the present invention are disclosed as preferred embodiments, but not limited thereto, and those skilled in the art will readily appreciate from the foregoing description that various extensions and modifications can be made without departing from the spirit of the present invention.
