Description

Technical Field

[0001] This utility model belongs to the field of visual inspection equipment technology, and specifically relates to a visual inspection and screening device. Background Technology

[0002] Visual inspection and sorting machines are high-precision inspection devices based on machine vision, optical imaging, and automated control technologies. They simulate human eyes to perform non-contact inspection of products and combine image processing algorithms to achieve defect identification, size measurement, and sorting. They are widely used in the quality control process of manufacturing industries. When the inspection instrument inspects products, the products are generally placed on a turntable inside the instrument. However, the turntable needs to be kept clean. Even a little dust will be detected by the optical detector, causing the product to be identified as unqualified. Therefore, the cleanliness of the turntable plays an important role in the pass rate of product inspection.

[0003] Chinese patent CN221515276U discloses a visual inspection and sorting machine, comprising a visual inspection and sorting device and a turntable auxiliary assembly mounted on the right side wall of the device. The device includes a body, a turntable within its internal cavity, and multiple sets of optical detectors positioned around the turntable. The auxiliary assembly includes a dust collection box, a fan mechanism inside the dust collection box, and a first and second air guide tube connected to the exhaust end of the fan mechanism. In this invention, by installing the turntable auxiliary assembly on the side wall of the visual inspection and sorting device, a servo fan unit draws air from the inside of the two air guide tubes to create negative pressure. This negative pressure is then used to remove dust from the rotating turntable surface via the air guide tubes within the body, thus preventing debris on the turntable surface from misleading the inspection and sorting process when an industrial camera is used to inspect workpieces.

[0004] However, while the above-mentioned technical solution can achieve the purpose of absorbing dust on the turntable, its first and second air guide tubes are relatively long in actual use. This results in a longer path for the extracted gas. Consequently, when the turbine fan generates negative pressure, the suction force is transmitted to the first and second air guide tubes near the turntable. At this point, the suction force is weak and it is difficult to completely absorb the dust. Furthermore, the size of the products being tested varies each time. This causes the dust or impurities that were pressed under the previous product to be exposed when the next product is tested. At the same time, the pressed dust and impurities are more tightly connected to the turntable, making them even more difficult to absorb. This affects the testing of subsequent products and has certain limitations in use. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a visual inspection and screening device includes a visual inspection and screening machine 1. Sealed doors 2 are hinged to both sides of the top surface of the visual inspection and screening machine 1. An exhaust port 3 is located in the middle of the bottom surface of the visual inspection and screening machine 1. A cavity 4 is formed inside the visual inspection and screening machine 1.

[0027] The sealing door 2 allows staff to easily open the visual inspection and screening machine 1 and place the product to be inspected inside. The exhaust port 3 facilitates the discharge of extracted gas. The cavity 4 allows the fan 5 to be fixed inside. The first electric telescopic rod 7 allows the cleaning frame 10 to move up and down a certain distance, making it easy to adjust the height of the second electric telescopic rod 9 and to retract the cleaning frame 10 into the cavity 4 when not in use. The second electric telescopic rod 9 can move the cleaning frame 10 left and right. The third electric telescopic rod 18 facilitates the movement of the optical detector 19 up and down a certain distance, bringing it closer to the product to be inspected.

[0028] The visual inspection and sorting machine 1 has an annular groove 11 inside, and an adjusting ring 15 is rotatably mounted inside the annular groove 11. A drive motor 13 is fixedly connected to one side of the bottom wall of the cavity 4. A gear 14 is fixedly connected to the output end of the drive motor 13. A rack 16 meshes with the surface of the gear 14, and the rack 16 is fixedly connected to the inner wall of the adjusting ring 15. The annular groove 11 allows the adjusting ring 15 to rotatably mount on its inner wall. The drive motor 13 drives the gear 14 to rotate, which in turn drives the rack 16 to rotate, and finally drives the adjusting ring 15 to rotate.

[0029] The inner wall of cavity 4 is provided with a clearance groove, and the rack 16 corresponds to the position of the clearance groove. Two vertical rods are fixedly connected to the top of the adjusting ring 15, and a turntable 17 is fixedly connected to the top of the vertical rods.

[0031] Example 2:

[0032] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a positioning block 22 is fixedly connected to the center of the bottom of the visual inspection and sorting machine 1. Fixing blocks 23 are fixedly connected to the center of both sides of the positioning block 22. An adjusting cylinder 24 is fixedly connected to one side of the fixing block 23. A pulling rod 25 slides through the interior of the adjusting cylinder 24, and the surface of the pulling rod 25 slides through the interior of the fixing block 23. An air supply pipe is fixedly connected to the outlet of the fan 5. A guide sleeve 21 is fixedly connected to the bottom of the air supply pipe, and the guide sleeve 21 is fixed and passes through the interior of the visual inspection and sorting machine 1 and the exhaust port 3. The arrangement of the fan 5, the extraction pipe 6, and the air supply pipe facilitates the adsorption of dust and impurities adhering to the turntable 17. The fixing block 23 facilitates the installation and fixation of the adjusting cylinder 24. The guide sleeve 21 ensures that the gas delivered by the air supply pipe accurately enters the exhaust port 3.

[0033] A pressing block is fixedly connected to one side of the surface of the pull rod 25, and a compression spring 26 is fixedly connected to one side of the pressing block. One end of the compression spring 26 is fixedly connected to one side of the inner wall of the adjusting cylinder 24. Abutting blocks are fixedly connected to the opposite ends of the two pull rods 25. Abutting grooves are provided on both sides of the exhaust port 3, and the surface of the abutting block penetrates the interior of the abutting groove.

[0034] Pulling rod 25 to the right causes it to drive the compression block to compress spring 26, thereby causing the contact block to disengage from the contact grooves on both sides of exhaust port 3, making it easier to disassemble exhaust port 3.

The insertion groove ensures that the connection between the exhaust port 3 and the positioning block 22 remains initially stable, and the filter plate 27 facilitates the filtration of dust and impurities contained in the gas transported by the gas pipe.

[0036] The working principle of this utility model is as follows: Before the staff needs to perform product testing, the drive motor 13 and the fan 5 are controlled to work. The output end of the drive motor 13 drives the gear 14 to rotate, and then the gear 14 drives the rack 16 meshing with it to rotate, thereby causing the adjusting ring 15 to rotate. The staff controls the first electric telescopic rod 7 to start, so that the height of the connecting shell 8 and the cleaning frame 10 is consistent with that of the cleaning frame 10. At the same time, the staff controls the second electric telescopic rod 9 to start. The output end of the second electric telescopic rod 9 drives the cleaning frame 10 to move closer to the cleaning frame 10, so that the turntable 17 is located inside the cleaning frame 10, and the scraper 12 contacts the top of the turntable 17. When the turntable 17 rotates, the dust and impurities adhering to the top are scraped off by the scraper 12. At the same time, the fan 5 works through the extraction pipe 6. Inhalation transmits suction to the extraction port 20, drawing out dust and impurities scraped off by the scraper 12. This is then transported through the air supply pipe to the guide sleeve 21, where it is finally filtered by the filter plate 27 and discharged. After the top of the turntable 17 is cleaned, the operator opens the sealing door 2 and places the product to be tested on the turntable 17. The operator can then control the third electric telescopic rod 18 to descend, causing it to drive the optical detector 19 to test the product. After prolonged use, the operator pulls the pull rod 25 outward, causing the pressing block on its surface to compress the compression spring 26. Subsequently, the contact blocks on the opposite ends of the two pull rods 25 disengage from the contact groove inside the exhaust port 3. The operator can then simply pull the exhaust port 3 outward and clean the filter plate 27 for future use.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
