Description

Technical Field

[0001] This utility model relates to the field of mask production and screening technology, and in particular to a medical mask testing and screening device. Background Technology

[0002] Medical mask testing and screening devices are used to test and screen the quality and performance of medical masks. They typically employ machine vision technology, using a high-resolution camera to capture images of the masks, and then using image processing algorithms to analyze the images, detecting the shape, size, surface defects, etc., and identifying substandard masks. Subsequently, a lifting and rotating structure drives a suction cup device to remove the substandard masks.

[0003] A search of Chinese patent publication number CN 220532283 U reveals a medical mask testing and screening device comprising: a support frame, with first fixing blocks fixedly connected to both sides of the support frame. This medical mask testing and screening device uses a second camera at the bottom of a suction cup to track and align with a damaged mask. An air pump is then activated to generate air pressure, which, through a hose, drives the suction port below the suction cup to create suction, adsorbing the damaged mask onto the bottom of the suction cup. A second motor then drives a second gear to rotate, which in turn rotates the first gear at the top of the second fixing block, causing the fixing frame to turn. The damaged mask is then discarded into a waste bin, while finished masks continue moving on a conveyor belt and fall into a finished product bin. This structure effectively screens unqualified masks, improving testing efficiency and reducing the workload of testing personnel, thus solving the problem of low efficiency in manual testing.

[0004] In existing technologies, the suction cups are circular, while most masks are rectangular. The circular suction cups cannot completely cover all parts of the rectangular mask, which easily leads to the rectangular mask not being firmly gripped. When moving the rectangular mask, it is easy for it to fall off, causing it to fall onto the production line and affecting the screening efficiency. Therefore, a new suction structure for the detection and screening device is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a medical mask testing and screening device to solve the problem mentioned in the background art, where the suction cup is circular while most masks are rectangular. The circular suction cup cannot completely cover all parts of the rectangular mask, which easily leads to the rectangular mask not being firmly gripped and falling off when the rectangular mask is moved, causing the rectangular mask to fall onto the production line and affecting the screening efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a medical mask testing and screening device, comprising:

[0008] The detection and screening device includes a rotating lifting rod and a receiving rod, with the receiving rod bolted to the side of the rotating lifting rod.

[0041] The air pump 204 is used to generate suction, and the main air hose 205 is used to connect the first air hose 206 and the second air hose 207. The arrangement of the first air hose 206 and the second air hose 207 ensures the uniform distribution of negative pressure in the rectangular suction cup 201.

[0042] It also includes a convenient unblocking component, which includes a receiving sleeve 301, a rectangular groove 302, a rectangular block 303, and a locking block 304. The rectangular suction cup 201 is fixedly connected to the receiving sleeve 301 at all four ends. The receiving sleeve 301 has a rectangular groove 302 in it. The rectangular contact plate 202 is fixedly connected to the rectangular block 303 at all four ends. The top of the rectangular block 303 is fixedly connected to the locking block 304. The locking block 304 is movably connected in the rectangular groove 302.

[0043] The mounting sleeve 301 provides a guarantee for the opening of the rectangular slot 302, and the rectangular block 303 provides a guarantee for the installation of the locking block 304.

[0049] The sealing rubber gasket 3010 ensures the tightness of the connection between the rectangular contact plate 202 and the rectangular suction cup 201, thereby reducing gas leakage and ensuring the suction effect.

[0050] Working principle: First, the sealing rubber gasket 3010 is snapped into the second slot 209. Then, the locking block 304 on the rectangular contact plate 202 is inserted into the rectangular slot 302. At this time, the other end of the sealing rubber gasket 3010 is snapped into the first slot 308. Then, the wing screw 307 is tightened between the second threaded slot 306 and the first threaded slot 305. Then, the detection and screening process is carried out. When an unqualified rectangular mask or other shaped mask is detected, the detection and screening device rotates the lifting rod 101 to drive the rectangular contact plate 202 downward. At this time, the air pump 204 is turned on, and negative pressure is generated at the rectangular suction cup 201 through the main air hose 205, the first air hose 206, and the second air hose 207. Then, the suction cup is used to draw out the mask. The air vent 203 adsorbs the substandard masks, and then the rotating lifting rod 101 of the detection and screening device rotates and moves the substandard masks to the collection point. When it is necessary to clean the rectangular contact plate 202 and unclog the first ventilation hose 206 and the second ventilation hose 207, the wing screw 307 is removed from the second threaded groove 306 and the first threaded groove 305, thereby disassembling the rectangular contact plate 202. Then, tools are used to process the rectangular contact plate 202, the first ventilation hose 206, and the second ventilation hose 207. This step ensures the firm adsorption of substandard masks during the screening process, prevents substandard masks from falling onto the production line during movement, and ensures screening efficiency.
