[0020] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below with reference to specific illustrations.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by terms such as "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end portion", "length", "outer end", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0022] Combined with the attached Figures 1 to 6 As shown, this embodiment discloses a detection and rejection device for female bending pipe fittings, including a rejection device 1, a vision detection device 2, and a chain plate conveyor 5. The vision detection device 2 and the rejection device 1 are sequentially arranged on the chain plate conveyor 5, and the vision detection device 2 is installed in front of the rejection device 1.

[0023] The rejection device 1 includes a servo motor 11, a transmission shaft 14, a rejection piece 14, a pillow block bearing 110, a motor mounting seat 12, an induction piece 18, a motor position sensor 17, a main body frame 15, and a rejection funnel 19. The main body frame 15 is arranged above the chain plate conveyor 5. The transmission shaft 14 and the rejection piece 16 are arranged inside the main body frame 15. The output end of the servo motor 11 is connected to one end of the transmission shaft 14 through a coupling 13. The other end of the transmission shaft 14 is connected to the pillow block bearing 110, and the pillow block bearing 110 is arranged on the main body frame 15. The rejection piece 16 is fixed on the transmission shaft 14. The servo motor 11 is fixed on the motor mounting seat 12, and the motor mounting seat 12 is installed and fixed on the main body frame 15. The motor mounting seat 12 is provided with a bearing assembly, and the bearing assembly is connected to the motor output shaft.

[0024] An induction piece 18 is fixed on the transmission shaft 14, and the motor position sensor 17 is fixed on the main body frame 15. The induction piece 18 is connected to the motor position sensor 17. When the servo motor 11 operates to drive the induction piece 18 on the transmission shaft to rotate, the motor position sensor 17 can sense the rotation position of the servo motor 11 through the induction piece 18 to ensure the correct start and stop of the servo motor 11.

[0025] A feed sensor 111 is arranged at the feed inlet of the main body frame 15, which can sense whether the female bending pipe fitting product 3 enters the rejection device 1.

[0026] Rejection funnels 19 are arranged on both sides of the main body frame 15, and a turnover box 4 is arranged below the rejection funnels 19. The unmarked female bending pipe fitting products 3 are rejected by the rejection piece 16 into the rejection funnels 19 and finally fall into the turnover box 4.

[0027] The chain plate conveyor line 5 is driven to rotate by a conveyor line motor 51. One end of the output shaft of the conveyor line motor 51 is provided with an encoder 52 for measuring the traveling distance of the chain plate conveyor line 5. The servo motor 11, the camera 21, the motor position sensor 17, the feeding sensor 111, and the encoder 52 are all connected to the PLC controller. The camera 21 transmits the product marking status to the PLC controller. At the same time, the encoder 52 starts to transmit the traveling distance of the chain plate conveyor line 5 to the PLC controller. When the traveling distance of the chain plate conveyor line 5 reaches the set value, the unmarked products are within the range that can be removed by the removal piece 16. The PLC controller then controls the start and stop of the servo motor 11 so that the removal device 1 can accurately remove the unmarked products.

[0028] The visual inspection device 2 includes a camera 21, a lifting adjustment mechanism 22, a protective cover 24, and a frame 23. The camera 21 is located above the chain plate conveyor line 5 and is aligned with the product marking or labeling position on the chain plate conveyor line 5. The camera 21 is fixed on the lifting adjustment mechanism 22. The lifting adjustment mechanism 22 is arranged on the frame 23. The protective cover 24 is arranged on the frame 23, and the camera 21 is located inside the protective cover 24.

[0029] The lifting adjustment mechanism 22 includes an adjustment handwheel, a lead screw, a lifting slider, and a guide rail. The adjustment handwheel is connected to the upper end of the lead screw. The lifting slider is arranged on the guide rail. The lead screw is threadedly connected to the lifting slider. The guide rail is fixed on the frame, and the camera 21 is fixed on the lifting slider. Rotating the adjustment handwheel can drive the lead screw to rotate. The rotation of the lead screw drives the lifting slider to move up and down along the guide rail. Rotating the adjustment handwheel can adjust the distance between the camera 21 and the sprocket conveyor belt 5.

[0030] During the production and use process, the chain plate conveyor line 5 conveys the female elbow pipe products 3. When passing through the visual inspection device 2 at this station, the visual inspection device 2 judges whether there is any missing marking or labeling at the product marking or labeling position. If it is found that there is a missing one, when the product passes through the subsequent removal device, the servo motor 11 operates, driving the transmission shaft 14 to rotate, and the missing marked products are removed by the removal piece 16. The products fall into the turnover box 4 below through the removal funnel 19. On the contrary, if the visual inspection device judges that the product has no missing marking or labeling, when the product passes through the removal device 1, the removal device 1 does not act, and the product passes through normally.

[0031] The utility model detects whether the female elbow pipe products are missing markings through the visual inspection device 2, and removes the unmarked products through the removal device 1, improving the production automation degree, reducing the labor cost, and improving the production efficiency.

[0032] The above are only the preferred embodiments of the present utility model, and do not impose any formal restrictions on the utility model. Any simple modifications, equivalent changes or decorations made to the above embodiments based on the technical principles of the present utility model still fall within the scope of the technical solutions of the present utility model.
