Technical Field
[0001] This utility model belongs to the field of robotic gripping mechanisms, specifically a quick-assembly robotic gripping mechanism. Background Technology
[0002] The robotic gripping mechanism is the core execution component of industrial robots or automated equipment. It is responsible for the stable gripping, handling or placement of target objects. It usually consists of a robotic arm and an end effector. The robotic arm drives the end effector to perform operations such as gripping or handling objects.
[0003] In traditional robotic gripping mechanisms, installation and disassembly typically rely on screw tightening. While this method can ensure the stability of the gripping mechanism to some extent, it has significant shortcomings in actual operation. When the robotic gripping mechanism needs to be disassembled for maintenance, screw tightening is often time-consuming and inconvenient. This cumbersome disassembly process not only increases the workload of maintenance personnel but also greatly reduces the rapid disassembly capability of the robotic gripping mechanism, thereby affecting the overall maintenance efficiency and production efficiency of the equipment.
[0004] In summary, this utility model provides a quick-assembly robotic gripping mechanism to solve the above problems. Utility Model Content

Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.
[0023] Example 1
[0024] like Figure 1-5As shown, this is the first embodiment of the present invention. This embodiment provides a quick-connect robotic gripping mechanism, including a quick-connect assembly 100, comprising an upper connector 110 installed at the end of the robotic arm, and a lower connector 120 located below the upper connector 110. The upper connector 110 includes a connecting cylinder 111, an externally threaded connecting ring 112 located at the bottom of the connecting cylinder 111, through grooves 113 formed on both sides of the surface of the connecting cylinder 111, and a cam handle 114 installed in the inner cavity of the through grooves 113. One end of the cam handle 114 extends into the inner cavity of the connecting cylinder 111. The lower connector 120 includes a connecting post 121, an internally threaded connecting ring 122 sleeved on the lower end of the surface of the connecting post 121, a slot 123 opened on the upper end of the surface of the connecting post 121, and limiting grooves 124 opened on both sides of the upper end of the connecting post 121. The internally threaded connecting ring 122 is threadedly connected to the externally threaded connecting ring 112. One end of the cam handle 114 located in the inner cavity of the connecting cylinder 111 is engaged with the inner cavity of the slot 123.
[0025] like Figure 1-5 As shown, the upper connector 110 is connected to the end of the robotic arm via the connecting cylinder 111. The connecting cylinder 111 has through grooves 113 on both sides. A cam handle 114 is installed inside the through groove 113. The cam handle 114 moves in the through groove 113 via a rotating shaft. One end of the cam handle extends into the inner cavity of the connecting cylinder 111 to lock the lower connector 120. The lower connector 120 includes a connecting post 121. Its surface is provided with an internal threaded connecting ring 122, which forms a threaded engagement with the external threaded connecting ring 112 of the upper connector 110. The upper end of the connecting post 121 is provided with a slot 123 and a limiting slot 124, which are used to engage with the cam handle 114 to achieve locking and positioning.
[0026] Align the limiting groove 124 on the surface of the lower connector 120 with the cam handle 114 inside the connecting cylinder 111, and then push the lower connector 120 into the connecting cylinder 111. After the lower connector 120 enters the connecting cylinder 111, rotate the lower connector 120 to disengage the cam handle 114 from the limiting groove 124 and into the retaining groove 123. Then press down on the cam handle 114 to engage it with the retaining groove 123. At this time, rotate the internal thread connecting ring 122 upward to fully engage the external thread connecting ring 112. Extending into the internal threaded connecting ring 122, the gripping component 200 is connected to the robotic arm. During disassembly, simply separate the internal threaded connecting ring 122 from the external threaded connecting ring 112, then lift the cam handle 114 to disengage it from the slot 123, and then rotate the connecting column 121 to align the limiting slot 124 with the cam handle 114. This allows the gripping component 200 connected to the lower connector 120 to be separated from the robotic arm, thus enabling quick assembly and disassembly of the gripping component 200.
[0027] Example 2
[0028] Reference Figure 1-3This is the second embodiment of the present invention, which is based on the previous embodiment.
[0029] In this embodiment, the external threaded connecting ring 112 is fixed to the bottom of the connecting cylinder 111, the connecting cylinder 111 is fixed to the end of the robotic arm by bolts, and the cam handle 114 is movably connected to the inner cavity of the through groove 113 by a rotating shaft.
[0030] The upper end of the connecting post 121 extends into the inner cavity of the connecting cylinder 111 and is slidably connected to the inner cavity of the connecting cylinder 111. When the connecting post 121 enters the inner cavity of the connecting cylinder 111, the cam handle 114 located at one end of the inner cavity of the connecting cylinder 111 slides along the inner cavity of the limiting groove 124 to the inner cavity of the slot 123.
[0031] like Figure 1-3 As shown, the cam handle 114 extends into the inner cavity of the connecting cylinder 111 through the through groove 113 and cooperates with the slot 123 of the lower connector 120 to form a snap-locking structure. The limiting groove 124 is used to guide the cam handle 114 to slide into place to ensure a stable and reliable connection. The lower connector 120 can be inserted into the upper connector 110 and the cam handle 114 can be pressed down to complete the fixation. No tools are needed. The snap-lock can be released by lifting the cam handle 114, which can achieve quick separation and improve installation efficiency.
[0032] Example 3
[0033] Reference Figure 1 , 2 4 and 5 are the third embodiment of this utility model, which is based on the first two embodiments.
[0034] In this embodiment, a gripping component 200 for gripping objects is installed at the bottom of the lower connector 120. The gripping component 200 includes a bracket 210, a top plate 220 located at the top of the bracket 210, and a gripping component 230 and a suction cup 240 for fixing objects. Two sets of gripping components 230 are provided and are located on both sides of the upper end of the bracket 210, respectively.
[0035] The top plate 220 is fixed to the top of the bracket 210, the connecting column 121 is fixed to the top of the top plate 220, and the suction cup 240 is fixed to the bottom of the bracket 210, and several suction cups 240 are provided.
[0036] The clamping assembly 230 includes clamping plates 231 located at both ends of the bracket 210, a cylinder 232 located at the top of the bracket 210, a rotating support 233 fixed to the top of the bracket 210 by a rotating shaft, and a pull rod 234 for connecting the clamping plates 231 and the rotating support 233.
[0037] One end of cylinder 232 is movably connected to a clamping plate 231 via a movable pin, and the output end of cylinder 232 is movably connected to another clamping plate 231 via a movable pin. The clamping plate 231 is movably connected to the bracket 210 via a rotating shaft. One end of pull rod 234 is fixedly connected to the rotating support 233 via a fisheye bearing, and the other end of pull rod 234 is movably connected to the clamping plate 231 via a movable pin.
[0038] like Figure 1 , 2 As shown in Figures 4 and 5, the clamping assembly 230 drives the clamping plate 231 to clamp via the cylinder 232. The cylinder 232 is linked to the rotating support 233 via the pull rod 234 to achieve synchronous clamping action. The suction cup 240 is used to adsorb objects on smooth surfaces, forming a clamping and suction combined gripping mode. The number of suction cups 240 is adjustable and they are distributed at the bottom of the bracket 210. While the clamping plate 231 is clamping, the suction cups 240 apply suction force to prevent the object from slipping.
[0039] In use, insert the lower connector 120 into the upper connector 110, rotate the lower connector 120, and then press down the cam handle 114 to make it engage with the slot 123. Then tighten the internal threaded connecting ring 122 and the external threaded connecting ring 112 to complete the mechanical connection. This process does not require tools, thus enabling quick installation of the gripping component 200 and the robotic arm. When disassembling, simply lift the cam handle 114 to make it engage with the slot 123, and then rotate the lower connector 120 in the opposite direction to pull it out of the upper connector 110. This allows the gripping component 200 to be separated from the robotic arm, thus achieving quick installation and separation and improving installation efficiency.
[0040] The robotic arm is positioned above the target object, and the output end of the cylinder 232 retracts. The extension and retraction of the cylinder 232 drives the clamping plate 231 to move inward or outward. The pull rod 234 is connected to the rotating support 233 through a fisheye bearing, and the other end is movably connected to the clamping plate 231. The pull rod 234 and the rotating support 233 cooperate to form a linkage structure, so that the clamping plate 231 moves in a coordinated manner and the clamping force is uniform. The clamping plate 231 is connected to the bracket 210 through a rotating shaft to realize the opening and closing movement, thereby enabling the clamping operation of the object.

[0042] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention.
