[0026] Please see Figure 1-5 The present invention provides a technical solution: a nut conveying device, comprising: a base 1; an auxiliary seat 2 and a nut vibrating plate 3 are fixedly connected to the top of the base 1 respectively, and a material feeding groove 14 is provided on the top of the auxiliary seat 2;

A support arm 5 is fixedly fixed to the top of the auxiliary seat 2. A mounting plate 6 is fixedly connected to one end of the support arm 5. A detection mechanism is provided on the outer wall of the mounting plate 6. A servo electric cylinder 8 is fixedly connected to the outer wall of the mounting plate 6, and a protective cover 9 is fixedly connected to one end of the telescopic shaft of the servo electric cylinder 8. A through hole is opened at the bottom of the protective cover 9, and a dustproof mechanism is provided around the through hole.

[0028] The testing mechanism includes a socket 7 fixedly connected to the outer wall of the mounting plate 6, and an industrial area scan camera 21 plugged into one end of the socket 7;

[0029] The dustproof mechanism includes a magnetic ring 10 fixedly connected to the outer wall of the protective cover 9, an iron ring 11 magnetically connected to one end of the magnetic ring 10, a transparent plate 12 fixedly connected to the inner wall of the iron ring 11, and a lever plate 13 fixedly connected to the outer wall of the iron ring 11.

[0030] The nuts are arranged in an orderly manner by a vibratory feeder and then conveyed to the feed chute 14 of the auxiliary seat 2 through the conveying square tube 4. The first cylinder 15 drives the push rod 17 to push the nuts along the feed chute 14. The second cylinder 16 drives the stop rod 19 to assist in controlling the feeding and distinguishing between qualified and unqualified nuts. The servo electric cylinder 8 installed on the support arm 5 can drive the protective cover 9 to move horizontally, which can provide a closed space for image detection and can also be moved horizontally to assist personnel in quick inspection and maintenance. The dustproof mechanism at the bottom of the protective cover further provides a closed and transparent protection function, effectively realizing the directional conveying, rhythm control and online visual inspection of nuts.

[0031] In a further preferred embodiment, the top of the auxiliary seat 2 is provided with a limiting groove 18 that communicates with the material feeding trough 14, and the stop rod 19 is slidably disposed between the limiting groove 18 and the material feeding trough 14. The outer wall of the stop rod 19 is provided with a material opening that fits the size of the material feeding trough 14.

[0032] The top of the auxiliary seat 2 is provided with a limiting groove 18 that communicates with the material feeding chute 14, so that the stop rod 19 can slide between the limiting groove 18 and the material feeding chute 14 to control the entry and exit of qualified and unqualified materials. The stop rod 19 has a material outlet with a size that matches the material feeding chute 14 to ensure material discharge.

[0033] More preferably, the push rod 17 is slidably disposed in the feed chute 14, and the stop rod 19 and the push rod 17 are arranged at 90 degrees to each other;

[0034] The push rod 17 pushes the nut forward in a straight line within the feed chute 14, while the stop rod 19 is arranged at a 90-degree angle to the push rod 17, achieving axial advancement and lateral obstruction respectively. The two work together to accurately push a single qualified nut to the picking point.

[0035] More preferably, an image processor 22 that is electrically connected to the industrial area scan camera 21 is fixedly connected to the outer wall of the mounting plate 6, and the shooting end of the industrial area scan camera 21 is vertically downward and facing the bottom through hole of the protective cover 9.

[0036] The industrial area array camera 21 is electrically connected to the image processor 22. The image processor 22 processes the visual image in real time and determines the state of the nut. The camera's shooting end is facing down and aligned with the through hole of the protective cover 9 for easy shooting.

[0037] More preferably, a conveying square tube 4 is fixedly connected between the material feeding trough 14 of the auxiliary seat 2 and the discharge end of the nut vibrating plate 3, and the end of the material feeding trough 14 of the auxiliary seat 2 is open and a collection frame 20 is provided at the opening.

[0038] The discharge end of the nut vibratory plate 3 is connected to the feed chute 14 of the auxiliary seat 2 through the conveying square tube 4. The square tube fits the size of the nut and guides the orientation to ensure that the nut is conveyed smoothly. The end of the feed chute 14 is open and a collection frame 20 is set below to collect unqualified nuts for centralized transfer.

[0039] Preferably, the bottom through hole of the protective cover 9 is vertically downward and faces the intersection of the conveying square tube 4 and the material feeding chute 14;

[0040] The bottom through hole of the protective cover 9 is vertically oriented towards the intersection of the conveying square tube 4 and the material feeding chute 14, providing a precise window for visual recognition and ensuring that the camera's field of view is consistent with the nut's running trajectory.

[0041] A specific application of this embodiment is as follows: Nuts are vibrated and aligned by the nut vibrating plate 3 and conveyed along the conveying square tube 4 to the material feeding chute 14 on the auxiliary seat 2, entering the inspection preparation area. The industrial area array camera 21 takes pictures of the nuts located at the feeding position of the material feeding chute 14 through the through hole of the protective cover 9. The image is transmitted to the image processor 22 for analysis and inspection to determine whether the nuts are qualified. After being determined to be qualified, the stop rod 19 slides in the limiting groove 18 and the material feeding chute 14 under the drive of the second cylinder 16, so that the material inlet of the stop rod 19 and the material feeding chute 14 are misaligned. The first cylinder 15 is started, and the push rod 17 pushes forward to push the qualified nuts to the position blocked by the stop rod 19, so that the robot or manual can pick them up. For unqualified nuts, the second cylinder 16 controls the material inlet of the stop rod 19 to fit with the material feeding chute 14, and the first cylinder 15 controls the push rod 17 to push forward to push the unqualified nuts out from the material inlet and the end of the material feeding chute 14 and send them into the collection frame 20 for collection, so as to facilitate subsequent transfer and centralized processing.

[0042] During the inspection process, the industrial area scan camera 21 forms a closed inspection space through the protective cover 9 to prevent interference from external light and dust impurities. The bottom of the protective cover 9 is magnetically attracted to the iron ring 11 by the magnetic ring 10, so that the transparent plate 12 can just close the through hole. This prevents dust from entering and causing pollution without affecting the shooting. In addition, the servo cylinder 8 can directly control the protective cover 9 against the camera to slide open, so that personnel can quickly and conveniently install and remove the industrial area scan camera 21 on the socket 7 for inspection and maintenance.
