[0024] Embodiment

[0025] As Figure 1 - Figure 7As shown in the figure, a visual inspection device for production line facial masks includes a lower housing 1. Shock-absorbing legs are installed at the four corners of the bottom wall of the lower housing 1. The shock-absorbing legs include rubber pads 2. A sliding rod 3 is fixedly connected to the upper surface of the rubber pad 2. A sliding tube 4 that is slidably connected to the sliding rod 3 is sleeved on the top end of the sliding rod 3. The top end of the sliding tube 4 is fixed to the bottom wall of the lower housing 1. A spring 5 is arranged in the inner cavity of the sliding tube 4. The two ends of the spring 5 are respectively fixed to the top end of the sliding rod 3 and the inner wall of the sliding tube 4. The rubber pad 2 is provided to protect the lower housing 1 and avoid as much as possible the problem that the bottom wall of the lower housing 1 directly contacts the ground and is easily damaged when being rubbed. The sliding rod 3, the sliding tube 4 and the spring 5 together form a damper structure for buffering and shock absorption by the user;

[0026] A facial mask transmission structure is installed on the lower housing 1. The facial mask transmission structure includes two side plates 12 fixedly installed on the top of the lower housing 1. Transmission shafts 13 are rotatably connected between the two ends of the two side plates 12. A transmission belt 14 that is drivingly connected to the transmission shafts 13 is arranged on the outer surfaces of the two transmission shafts 13. A first servo motor 15 for driving the transmission shaft 13 to rotate is also installed on one of the side plates 12. A plurality of through holes are equidistantly formed in the transmission belt 14. A transparent holding film 16 is fixedly installed in the through holes. The size of the transparent holding film 16 is adapted to the size of the facial mask. When the transparent holding film 16 above the transmission belt 14 rotates to be aligned with the detection device, the transparent holding film 16 below rotates to coincide with the position of the transparent holding film 16 above at the same time. During use, the user can place the facial mask to be visually inspected on the transparent holding film 16, and then start the first servo motor 15 to drive the transmission belt 14 to rotate through the first servo motor 15, thereby driving the facial mask placed on the transparent holding film 16 to move into the lower housing 1;

[0027] A lower support plate 6 is fixedly installed in the inner cavity of the lower housing 1 along the length direction of the lower housing 1. Partition plates 7 are fixedly connected to both sides of the lower support plate 6. A waste collection cavity 8 and a tool storage cavity 9 are respectively formed between the two partition plates 7 and the inner side wall of the lower housing 1. The partition plates 7 are provided to partition the inner cavity of the lower housing 1 to form the waste collection cavity 8 and the tool storage cavity 9. The waste collection cavity 8 is used to collect the facial mask waste that fails the inspection, and the tool storage cavity 9 is used to store the maintenance tools of the whole device, which is convenient for maintenance when the whole device breaks down;

[0028] Openings are formed on the outer walls of the waste collection cavity 8 and the tool storage cavity 9. Sealing doors 10 are hinged in the openings. Handles 11 are fixedly installed outside the sealing doors 10. The sealing doors 10 are provided to seal the openings of the waste collection cavity 8 and the tool storage cavity 9 to increase the aesthetics of the whole device. The handles 11 are provided to facilitate the user to open the sealing doors 10 to take out the maintenance tools or the facial mask waste;

[0029] The top of the lower housing 1 is fixedly connected to the upper housing 17. Feeding ports 18 for accommodating the mask transmission device are provided at both ends of the upper housing 17, enabling the mask to enter the upper housing 17 through the feeding ports 18.

[0030] A control panel 23 is installed on the upper housing 17. An upper support plate 19 arranged in alignment with the lower support plate 6 is fixedly installed in the inner cavity of the upper housing 17. Detection devices for visually inspecting the mask are symmetrically installed in the inner cavities of the lower housing 1 and the upper housing 17. The detection device includes two detection cameras 20 symmetrically installed on the lower support plate 6 and the upper support plate 19. The detection ends of the two detection cameras 20 are both arranged in alignment with the center of the transparent holding film 16. The detection cameras 20 are connected to the control panel 23, and the control program can be set through the control panel 23. When the mask is conveyed to be in alignment with the detection cameras 20, the detection cameras 20 can capture the mask image and transmit it into the control panel 23, and the captured photo is visually inspected by the AL algorithm through the control panel 23.

[0031] Lamp holders 21 are fixedly installed on the lower support plate 6 and the upper support plate 19 on both sides of the detection cameras 20. Supplementary light lamps 22 are installed on the lamp holders 21. A condenser plate with an arc-shaped structure is installed on the inner wall of the lamp holder 21. The lamp holders 21 are arranged on both sides of the detection cameras 20 to install the supplementary light lamps 22 for supplementary lighting, trying to avoid the dim light inside the device affecting the detection result. The condenser plate is provided for the condensing effect, enabling the light to be reflected and concentrated on the detection position through the condenser plate, improving the supplementary lighting effect.

[0032] A gas collecting hood 24 is fixedly installed on the inner wall of one end of the lower housing 1. A second servo motor 25 is fixedly installed inside the gas collecting hood 24. A fan blade 26 is fixedly connected to the output end of the second servo motor 25. An air suction hole 27 communicating with the inner cavity of the gas collecting hood 24 is provided at one end of the lower housing 1 close to the gas collecting hood 24. An air blowing pipe 28 is installed on one side wall of the gas collecting hood 24. The end of the air blowing pipe 28 far from the gas collecting hood 24 extends upward to the upper side of one side of the mask transmission structure and is fixed to the mask transmission structure. The second servo motor 25 is electrically connected to the control panel 23. When the mask with unqualified detection result moves to the position of the air blowing pipe 28 along the conveyor belt 14, the control panel 23 will immediately control the second servo motor 25 to start, driving the fan blade 26 to rotate at high speed, sucking the air in the external environment into the gas collecting hood 24, and discharging the high-speed flowing air along the air blowing pipe 28, acting on the mask from the side, and blowing the mask with unqualified detection result into the waste collection cavity 8 from the side, realizing the sorting of unqualified masks, which is not only convenient to use but also greatly improves the detection efficiency.

[0033] It should be noted that for the visual inspection device for facial masks on a production line, when in use, the first servo motor 15 is started to drive the conveyor belt 14 to rotate. Then, the facial masks to be inspected are successively placed on the transparent holding film 16 installed on the conveyor belt 14. When the first servo motor 15 drives the conveyor belt 14 to rotate and convey the facial mask to the inspection station of the inspection camera 20, the transparent holding films 16 on the upper and lower sides of the conveyor belt 14 coincide. At this time, the two inspection cameras 20 can capture the facial mask images from the upper and lower sides and transmit them to the control panel 23. The control panel 23 uses the AL algorithm to perform visual inspection on the facial masks and determine whether the facial masks meet the requirements. After the inspection is completed, the facial masks continue to move with the conveyor belt 14. When the facial masks with unqualified inspection results move to the position of the air blowing pipe 28 with the conveyor belt 14, the control panel 23 will immediately control the second servo motor 25 to start, driving the fan blades 26 to rotate at high speed, sucking the air in the external environment into the air collecting hood 24, and discharging the high-speed flowing air along the air blowing pipe 28, acting on the facial masks from the side, and blowing the facial masks with unqualified inspection results into the waste collection chamber 8 from the side. When the facial masks with qualified inspection results pass through the position of the air blowing pipe 28, the second servo motor 25 does not start, enabling the facial masks to be conveyed to the end of the conveyor belt 14 for subsequent processing, thereby realizing the automatic sorting of facial masks, which is not only convenient to use but also greatly improves the inspection efficiency.

[0034] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
