[0018] Example

[0019] Please see Figures 1-2This utility model provides a front-back error prevention device for articulated arm parts with internal convex rings, suitable for loading and unloading. It includes a welding fixing frame 1, an error-prevention flipping frame 2 above the welding fixing frame 1, a detection plate 3 on one side of the error-prevention flipping frame 2, and a part 10 on the detection plate 3. A connecting groove is formed on the lower surface of the detection plate 3, which is adapted to a contact sensor 7. The detection plate 3 is connected to the error-prevention flipping frame 2 via a pushing assembly, and a front-back identification component is located on the lower side of one side of the detection plate 3.

[0020] On the other side of the error-proof flipping frame 2, a positioning component is provided. The positioning component includes a flipping positioning plate 9, on which a positioning groove 91 is provided. The positioning groove 91 facilitates the placement of part 10 and the retrieval of part 10 by the articulated arm. Several limiting posts 92 are provided on the outer edge of the positioning groove 91 to position the part 10.

[0021] The pushing assembly includes multiple linear bearings 4 mounted on the error-proof flipping frame 2. Each linear bearing 4 contains an error-proof optical shaft 5, and a spring 6 is fitted around the outside of the error-proof optical shaft 5. The top end of the spring 6 and the top end of the error-proof optical shaft 5 are connected to the lower surface of the detection disk 3, and the bottom end of the spring 6 is connected to the upper surface of the linear bearing 4. When the detection disk 3 is pressed down, the error-proof optical shaft 5 can move downward within the linear bearing 4. When the pressure above is removed, the detection disk 3 moves upward and resets due to the action of the spring 6, and the error-proof optical shaft 5 moves upward within the linear bearing 4.

[0022] The front / back recognition component includes a contact sensor 7, which is positioned below the detection plate 3 and fixed to the error-proof flipping frame 2 via a fixing plate 8. The contact sensor 7 is electrically connected to the controller, transmitting signals to it. The controller controls the articulated arm to perform different actions based on the signals. If the part 10 is face up, the controller controls the articulated arm to continue the unloading operation; if the part 10 is face down, the controller controls the articulated arm to place the part 10 on the flipping positioning plate 9, flipping and picking up the part 10 for unloading. The controller and articulated arm are mature existing technologies in the field, and their connection is also a mature electrical connection, which will not be described further here.

[0023] The error-proof flipping frame 2 has a U-shaped groove 21 on the side near the flipping positioning plate 9, which facilitates the articulated arm to perform picking operations. Rectangular grooves 22 are provided on both sides of the U-shaped groove 21, and the rectangular grooves 22 are passed through by the limiting post 92, which is used to fix the limiting post 92.

[0024] In this embodiment, part 10 has an internal convex structure. The distance from the internal convex structure to the front side of part 10 is 12.5 mm, and the distance from the internal convex structure to the back side of part 10 is 18 mm.

[0025] In practical use, the articulated arm picks up any face-up part 10 and places it on the detection plate 3, ensuring that part 10 and detection plate 3 are concentric. After placement, the articulated arm presses down according to a preset program. If part 10 is face-up, the pressing action causes the detection plate 3 to move downwards. The error-proof optical axis 5 moves downwards within the linear bearing 4 under the drive of the detection plate 3. At this time, the contact sensor 7 contacts the connecting groove on the lower surface of the detection plate 3 and outputs a signal to the controller. The controller then controls the articulated arm to unload the part. If part 10 is face-down, the pressing action causes the detection plate 3 to move downwards. However, because the concave part 10 reaches the front and back sides at different distances, the detection plate 3 cannot reach the contact distance with the contact sensor 7 when moving downwards. At this time, the controller controls the articulated arm to place part 10 on the flip positioning plate 9 and then picks up part 10 in the opposite direction for unloading.

[0026] Therefore, this utility model adopts the above-mentioned anti-mistake device for front and back sides of parts with inner convex rings suitable for loading and unloading articulated arms. By setting a pushing component, the detection plate can move under the downward pressure of the articulated arm. With the recognition function of the front and back recognition component, parts with different faces facing up can be quickly sorted. With the flipping positioning plate, the articulated arm can quickly flip and pick up the parts for unloading.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
