Among them, the first gear structure 112 of the first robotic arm 11 is installed on the power output shaft 21, and the second gear structure 122 of the second robotic arm 12 is installed on the cylindrical shaft 22. When the driving motor drives the first gear structure 112 to rotate through the power output shaft 21, the first gear structure 112 drives the second gear structure 122 to rotate around the cylindrical shaft 22, thereby realizing the relative movement of the two robotic arms.

In this embodiment, the first clamping part 111 includes a first clamping surface 1111, the second clamping part 121 includes a second clamping surface 1211, and the magnets are respectively arranged at the corresponding positions of the first clamping surface 1111 and the second clamping surface 1211.

[0063] Embodiment 2

[0064] Combined with Figures 3 - 8 As shown in the figure, the clothing picking device 1 further includes: a base 40, the picking assembly 10 and the driving member 20 are installed on the base 40; the base 40 is provided with at least one second self-locking structure, and the second self-locking structure cooperates with the first self-locking structure to keep the state of the picking assembly 10 unchanged.

[0065] Specifically, the driving member 20 is installed in the base 40, and the power output end and the cylindrical shaft 22 of the driving member 20 pass through the surface of the base 40 and are respectively assembled with the first gear structure 112 and the second gear structure 122; when the driving member 20 drives the two robotic arms to move relative to each other through the first gear structure 112 and the second gear structure 122, as Figure 7 shown in (c), the first robotic arm 11 and the second robotic arm 12 move away from each other to loosen the clothing, as Figure 7As shown in (d), the first robotic arm 11 and the second robotic arm 12 approach each other to pick up the clothes.

[0066] In some embodiments, the first self-locking structure includes a clamping protrusion provided on the robotic arm, and the second self-locking structure includes a clamping groove 41 provided on the base 40.

[0067] When the robotic arm moves to a specific position driven by the driving member 20, the clamping protrusion snaps into the clamping groove 41 to lock the robotic arm, so that a stable and effective clamping force is maintained between the two robotic arms; and the structure is simple, easy to install, and has a low cost.

[0068] In some embodiments, a set of clamping protrusions and clamping grooves can be provided; in other embodiments, in order to further match different clothes picking thicknesses and improve the reliability of the picking function, two or more sets of clamping protrusions and clamping grooves can also be provided.

[0069] Furthermore, the first self-locking structure and the second self-locking structure are located between the first gear structure 112, the second gear structure 122 and the base 40; specifically, a first protrusion 114 is provided at the first gear structure 112, a second protrusion 124 is provided at the second gear structure 122, and a first groove 411 and a second groove 412 are respectively provided at corresponding positions on the surface of the base 40.

At this time, the first protrusion 114 moves along the first guide chute 421, and the second protrusion 124 moves along the second guide chute 422. When the first protrusion 114 is clamped into the first groove 411 and the second protrusion 124 is clamped into the second groove 412, the locking of the robotic arm is achieved, that is, the first robotic arm 11 and the second robotic arm 12 maintain a stable and reliable clamping force on the picked clothes.

[0071] Furthermore, the clamping protrusion is an elastic component; when the clamping protrusion slides in the guiding chute 42, the clamping protrusion is squeezed into a compressed state; when the clamping protrusion moves to the clamping groove 41, the clamping protrusion resets under the action of elastic force to be buckled with the clamping groove 41. In this embodiment, after the adjustment is in place, the elastic automatic reset buckling of the clamping protrusion is used for locking, which has a simple structure and is convenient to use; and the elastic clamping protrusion is more likely to be disengaged from the clamping groove 41 when the driving member 20 applies a force, reducing damage caused by rigid collision.

[0075] Embodiment 3

[0076] Combined with Figure 9 shown, the clothing picking device simultaneously has the magnetic adsorption type self-locking structure described in Embodiment 1 and the protrusion-groove type self-locking structure described in Embodiment 2.

[0077] The magnetic adsorption type self-locking structure includes magnets 30 installed on each robotic arm, and the robotic arms are adsorbed and clamped to each other under the magnetic adsorption; in this way, the robotic arms can provide a stable clamping force, and the installation structure is simple, reducing costs.

[0078] The protrusion-groove type self-locking structure includes at least one set of clamping protrusions provided on the robotic arm and a clamping groove 41 provided on the base 40; or at least one set of clamping grooves provided on the robotic arm and a clamping protrusion provided on the base.

[0079] In this embodiment, by combining the magnetic adsorption type self-locking structure in Embodiment 1 and the protrusion-groove type self-locking structure in Embodiment 2, it is ensured that the robotic arm can provide sufficient clamping force for the clothing, further improving the stable reliability of the clamping effect on the clothing.
