[0034] As shown in Figures 1 to 8 , it is a clamp assembly 100 of an embodiment of the present application.
[0035] As shown in Figure 1 and Figure 2 , the clamp assembly 100 comprises a base 10 and a hook claw unit 20 mounted on the base 10. Wherein, the base 10 is used for carrying the hook claw unit 20, and is used for connecting the mechanical hand. The hook claw unit 20 is used for positioning and grabbing the loudspeaker 200.
[0036] In the following, the clamp assembly 100 described above is further described in combination with Figures 1 to 8 .
[0037] As shown in Figure 3As shown, the base 10 is provided with a connecting shaft 11 for connecting the mechanical arm. In the present scheme, the base 10 can have various specific implementations as long as it meets the needs of bearing the hook claw units 20 and connecting the mechanical arm.
[0038] For example, as shown in Figure 1 and Figure 2 In the present embodiment, the base 10 can further include a bottom plate 12 and a top plate 13 arranged parallel to the bottom plate 12. The bottom plate 12 and the top plate 13 form a receiving layer for accommodating the hook claw units 20. The connecting shaft 11 is vertically arranged between the bottom plate 12 and the top plate 13. In operation, the bottom plate 12 can be used to abut against the horn 200, playing a limiting role. The receiving layer formed by the bottom plate 12 and the top plate 13 can protect the hook claw units 20.
[0039] As shown in Figure 3 The number of the hook claw units 20 is multiple and evenly spaced around the connecting shaft 11. For example, in the present embodiment, the number of the hook claw units 20 is three and arranged in a triangular shape. The three hook claw units 20 cooperate to perform three-point positioning on the horn 200, with high stability in grabbing. Understandably, in other embodiments, the number of the hook claw units 20 can also be two, four, five or more.
[0040] As shown in Figure 4 and Figure 5 Each hook claw unit 20 includes a swing arm 21 hinged at one end to the base 10, a driver 22 connected to the swing arm 21, a connecting rod 23 mounted at the other end of the swing arm 21, and a hook plate 24 mounted on the connecting rod 23. In combination Figure 1 and Figure 3 In the present embodiment, one end of each swing arm 21 is hinged between the bottom plate 12 and the top plate 13. As shown in Figure 6 The swing arm 21 drives the connecting rod 23 to swing under the drive of the driver 22, so as to drive the connecting rod 23 to abut against the outside of the peripheral edge of the horn 200 and the hook plate 24 to hook the bottom of the peripheral edge of the horn 200. For example, in the present embodiment, in operation, the driver 22 drives the swing arm 21 to swing counterclockwise with the respective hinge points as the centers to achieve the purpose of folding and grabbing.
[0041] In the present scheme, the specific structure of the hook claw unit 20 will be different according to the specific selection of the driver 22.
[0042] For example, as shown in Figure 4 In the present embodiment, the driver 22 includes a fixed block 221 and a telescopic cylinder 222. The fixed block 221 is mounted on the base 10. The cylinder body of the telescopic cylinder 222 is hinged to the fixed block 221, and the piston rod of the telescopic cylinder 222 is hinged to the swing arm 21. As shown in Figure 6As shown, when the telescopic qigong performs the action of extending or shortening, it pulls the swing arm 21 to swing. At the same time, as the swing arm 21 swings, the hinge point of the piston rod of the telescopic cylinder 222 and the hinge point of the cylinder body will also rotate adaptively, so that the telescopic cylinder 222 adjusts its posture to match the angle of the swing arm 21.
[0043] For example, in other embodiments, if the actuator 22 is a rotary cylinder, the actuator 22 can be mounted on the hinge end of the swing arm 21.
[0044] For example, in other embodiments, if the driver 22 is a motor, it can be used with a lead screw drive structure to drive the swing arm 21 to swing, or the driver 22 can directly drive the hinge end of the swing arm 21 to swing.
[0045] To better protect the speaker 200, in some embodiments, the outer periphery of the connecting rod 23 may be provided with an elastic sleeve (e.g., a silicone sleeve, a rubber sleeve, or a foam sleeve). When gripping the speaker 200, the elastic sleeve can act as a buffer, reducing the risk of deforming the speaker 200's frame.
[0046] To improve the stability of the gripper 200, the hook plate 24 can also be improved. For example, as... Figure 5 As shown, in this embodiment, the top surface of the hook plate 24 is provided with anti-slip texture 241. The anti-slip texture 241 can increase the coefficient of friction between the top surface of the hook plate 24 and the bottom of the periphery of the speaker 200, thereby improving the stability of gripping.
[0047] Furthermore, considering that the speaker 200 may have various shapes, such as round, rectangular, or irregular, from a versatility perspective, such as... Figure 6 As shown, in this embodiment, the hook plate 24 has a disc structure. The disc-shaped hook plate 24 can be adapted to various shapes of horns 200, making it widely applicable.
[0048] Brief description of working principle:
[0049] like Figure 7 As shown, during operation, the base 10 is connected to a robotic arm, which moves to the location of the speaker 200 to be grasped under the robotic arm's influence. Then, combined with... Figure 6 The driver 22 of the hook unit 20 drives the swing arm 21 to swing, causing the connecting rod 23 and the hook plate 24 to swing accordingly, until the connecting rod 23 is close to the outer periphery of the speaker frame 200. At this time, as Figure 8 As shown, the hook plate 24 is precisely hooked onto the bottom perimeter of the speaker 200's frame, and multiple claw units 20 work together to securely lock the speaker 200 in place. Finally, the robotic arm moves the base 10, allowing the speaker 200 to be transferred.
[0050] The clamp assembly 100 uses the hook claw unit 20 to laterally position the periphery of the basket of the loudspeaker 200 and hook the bottom, and uses the hooking mode to realize stable grabbing of the loudspeaker 200, that is, stable grabbing can be provided, the risk of deforming the loudspeaker 200 during clamping can be reduced, and the clamp can be applied to a circular loudspeaker 200.
[0051] The technical features of the above embodiments can be combined in any manner, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered as within the scope of the present disclosure.
[0052] The above embodiments only express the preferred implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
