[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0025] This utility model provides a rotary gripping mechanism for automated nut feeding, such as... Figure 6 As shown, the nut 100 includes a nut sleeve 120 with a hollow channel 110. One end of the nut sleeve 120 is provided with an annular cap 130, and the annular cap is provided with a plurality of bent inserts 140.

[0026] like Figures 1 to 5 As shown, it includes a rotating base body 1 with rotational displacement, and the rotating base body 1 has several nut picking mechanisms 2 evenly spaced along the rotation direction.

[0027] The nut picking mechanism 2 includes a clamping part 3 for clamping the outer peripheral wall of the annular cap and a telescopic positioning part 4 for positioning relative to the nut sleeve. The telescopic positioning part 4 has a positioning pin end 40 that is linearly displaced toward the clamping part and is used to cooperate with the hollow channel.

[0028] Detailed implementation process and principle explanation: Nuts 100 are fed by a front-end aligning feeding device, while the rotary gripping mechanism in this case is used to position, pick up, and transfer the supplied nuts 100 one by one.

[0029] The rotating gripping mechanism is mounted on a robotic arm or a rotating base with both circumferential and rotational displacements. The transfer mechanisms of the robotic arm and the rotating base are existing technologies, and their displacement and drive will not be described in detail.

[0030] When the rotary gripping mechanism picks up the nut 100, it first aligns the nut picking mechanism 2 with the nut 100. The telescopic positioning part 4 is linearly displaced so that the positioning pin end 40 passes into the hollow channel 110, thereby satisfying the axial positioning of the nut 100. While the positioning pin end 40 is in the positioning state, the clamping part 3 clamps and locks the annular cap edge 130.

[0031] After one nut-picking mechanism 2 picks up a nut, the main body 1 of the turnover base rotates to switch the position of the next nut-picking mechanism 2, thus meeting the requirement of accurately aligning and picking up multiple nuts at one time.

[0032] In one specific embodiment, the nut picking mechanism 2 includes a picking carrier plate 20, on which a clamping base 21 for mounting a clamping part is provided. The telescopic positioning part 4 includes a telescopic drive source 41 disposed on the picking carrier plate. A guide pin 42 that passes through the clamping base is connected to the telescopic drive source. The positioning pin end is disposed on the free end of the guide pin.

[0033] Specifically, the pickup plate 20 meets the mounting requirements of the clamping part 3 and the telescopic positioning part 4. The design of the clamping part base 21 can guide the guide pin 42, ensuring accurate relative position with the clamping part 3, and also meeting the requirements for reliable and stable linear displacement accuracy.

[0034] In one specific embodiment, the free end of the guide pin 42 is provided with a cylindrical boss 420, and the positioning pin end is provided on the end face of the cylindrical boss. The diameter of the cylindrical boss is smaller than the outer diameter of the annular cap.

[0035] Specifically, the locating pin end is used to cooperate with the hollow channel 110 for positioning. After the nut is transferred to the position, the clamping part 3 releases the nut. After the nut is placed in the installation position, the guide pin 42 is pushed forward, and the cylindrical boss can release pressure on the cap edge to meet the requirements of pre-embedded assembly.

[0036] In one specific embodiment, the pickup carrier 20 is detachably mounted on the turnover base body.

[0037] This satisfies the changeover requirements of the nut picking mechanism 2 and allows for flexible assembly to adapt to various nut specifications.

[0038] In one specific embodiment, the clamping part 3 includes two clamping blocks 31 with relative linkage opening and closing displacement, and the clamping end face of any clamping block is provided with an arc-shaped groove 32 that cooperates with the outer peripheral wall of the annular cap.

[0039] By opening and closing the two clamping blocks 31 relative to each other, the clamping, locking and releasing operations of the arc-shaped groove 32 are satisfied, thus ensuring the stability of the clamping and locking of the cap brim.

[0040] In one specific embodiment, the clamping part includes a clamping pneumatic seat, and any clamping block is slidably disposed on the clamping pneumatic seat.

[0041] The clamping part uses a pneumatic finger actuator to meet the requirements of high-precision linkage clamping control. The actuator of the pneumatic finger is existing technology and will not be described in detail here. Any mechanism that only needs to drive the clamping block 31 is within the protection scope of this case.

[0042] In one specific embodiment, the main body 1 of the turnover base includes a horizontal carrier plate 10, and a mating flange 11 is provided at the geometric center of the horizontal carrier plate 10. The horizontal carrier plate includes a plurality of extended carrier arms 12 that are evenly spaced around the mating flange, and a nut picking mechanism is detachably provided on any of the extended carrier arms 12.

[0043] Specifically, the combination of the horizontal carrier plate 10, the mating flange 11, and the extension carrier arm 12 satisfies the flexible mounting requirements of the nut picking mechanism, and the structural strength is reliable and stable, meeting the requirements for rapid mating and cooperation with the robotic arm.

[0044] As can be seen from the above description, this utility model meets the needs of automated picking and turnover of specific nuts. It possesses high positioning and guiding accuracy and gripping stability, and utilizes rotational displacement to grip multiple nuts, significantly improving material turnover efficiency. Picking is precise and reliable, with improved fault tolerance, and the mechanism is convenient, quick to assemble, and simple to control.

[0045] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus / device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent in such process, method, article, or apparatus / device.

[0046] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
