[0031] The clamping mechanism holds the material with multiple jaws, which need to open simultaneously to prevent the material from tilting and affecting subsequent operations.

[0032] The following is a preferred embodiment of a gripper material gripping drive mechanism provided by this utility model that can solve the above technical problems.

[0033] A preferred embodiment of this utility model provides a gripper-driven mechanism for handling material pieces. Please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8The gripper material handling drive mechanism includes a support frame 11, multiple grippers 12, multiple elastic elements 13, and a drive device 14. The support frame 11 has multiple through slots 111. Each gripper 12 includes a first arm 121 and a second arm 122 connected together. The connection between the first arm 121 and the second arm 122 is rotatably connected to the support frame 11. The second arm 122 extends downwards through the through slots 111 and to the bottom of the support frame 11, and is used to grip materials. Multiple elastic elements 13 are respectively connected to the first arm 121 of each gripper 12. The elastic elements 13 provide elastic force to rotate the first arm 121 upwards, thereby enabling the second arm 122 to grip materials. The driving device 14 includes a driving plate 141, which is horizontally arranged and vertically movably arranged above the first arm 121 of each gripper 12 and abuts against the first arm 121. When the driving plate 141 moves downward, it can drive the first arm 121 of multiple grippers 12 to rotate downward simultaneously, thereby causing the second arm 122 of multiple grippers 12 to release the material simultaneously.

[0034] In this embodiment, the drive plate 141 is horizontally arranged with the support frame 11 as a guide to facilitate the installation of the drive plate 141. Of course, as another implementation, the drive plate 141 can also be horizontally arranged with other structural components of the gripper material gripping plate drive mechanism as a guide according to structural needs.

[0035] The gripper material-grabbing drive mechanism of this invention, when it is necessary to release the material piece, the drive plate 141 moves from a high position to a low position, forcing the first arm 121 of each gripper 12 to rotate downwards simultaneously, thereby causing the second arm 122 of each gripper 12 to release the material simultaneously. At this time, multiple elastic elements 13 simultaneously store energy. When it is necessary to grip the material piece, the drive plate 141 moves from a low position to a high position, and multiple elastic elements 13 simultaneously release energy. The elastic elements 13 provide elastic force to make the first arm 121 rotate upwards, thereby enabling the second arm 122 to grip the material piece. The gripper material-grabbing drive mechanism of this invention can, through the drive plate 141, cause the second arm 122 of each gripper 12 to release the material piece simultaneously, avoiding the tilting of the material piece and affecting subsequent operations.

[0036] Please refer to Figure 5 The top of the first arm 121, away from the second arm 122, is provided with an arc-shaped first protrusion 1211, which is used to abut against the bottom surface of the drive plate 141. The abutment between the drive plate 141 and the first protrusion 1211 can reduce the friction between the drive plate 141 and the first arm 121, so that the first arm 121 can rotate smoothly.

[0037] Please refer to Figure 3 and Figure 8The support frame 11 is also provided with a first receiving groove 112, and the elastic element 13 is set as a compression spring. The elastic element 13 is disposed in the first receiving groove 112, and the top end of the elastic element 13 abuts against the first support arm 121. The elastic element 13 is located in the first receiving groove 112, which can avoid interference from external structures. The elastic element 13 is set as a compression spring for easy assembly into the first receiving groove 112.

[0038] Please refer to Figure 5 A second protrusion 1212 is provided at the bottom of the first arm 121 away from the second arm 122, and the second protrusion 1212 extends into the inner cavity of the elastic member 13. With the above structure, the first arm 121 is not easily separated from the elastic member 13, thereby making the rotation of the first arm 121 stable.

[0039] Please refer to Figure 6 and Figure 8 The support frame 11 is also provided with multiple second receiving slots 113. A rotating shaft 15 is provided at the connection between the first arm 121 and the second arm 122. The gripper 12 is rotatably connected to the support frame 11 via the rotating shaft 15. The two ends of the rotating shaft 15 are respectively rotatably disposed in the two second receiving slots 113. The first receiving slot 112, the second receiving slot 113, and the through slot 111 at the same gripper position are connected. The rotating shaft 15 at the connection between the first arm 121 and the second arm 122 allows the gripper 12 to rotate smoothly. The two ends of the rotating shaft 15 are respectively rotatably disposed in the two second receiving slots 113, which can prevent external structures from interfering with the rotating shaft 15. The connection between the first receiving slot 112, the second receiving slot 113, and the through slot 111 facilitates processing and installation.

[0040] Please refer to Figure 5 and Figure 6 A mounting hole 123 is provided at the connection between the first arm 121 and the second arm 122. The axis of the mounting hole 123 is parallel to the axis of the rotating shaft 15, and the rotating shaft 15 passes through the mounting hole 123. A notch 124 is also provided at the connection between the first arm 121 and the second arm 122, and the notch 124 communicates with the mounting hole 123. With the above structure, it is convenient to install the rotating shaft 15 into the mounting hole 123.

[0041] Please refer to Figure 8 The bottom of the second receiving groove 113 is provided with a threaded hole 114. The gripper material gripping drive mechanism also includes a screw (not shown in the figure) and a cover plate (not shown in the figure). The cover plate covers the two second receiving grooves 113 corresponding to the same gripper 12, and the screw passes through the cover plate and connects with the threaded hole 114. With the above structure, the rotating shaft 15 can be confined in the two second receiving grooves 113.

[0042] Please refer to Figure 4The drive plate 141 is provided with a plurality of protrusions 1411, which extend horizontally and abut against a plurality of first arms 121 respectively. With the above structure, the overall size of the drive plate 141 can be small and the structure compact.

[0043] Please refer to Figure 2 The support frame 11 is provided with a guide post 115 extending vertically, and the drive plate 141 is slidably connected to the guide post 115. The drive device 14 also includes a cylinder 142, which is fixed to the top of the guide post 115, and the piston rod of the cylinder 142 abuts against the drive plate 141. The guide post 115 can both stabilize the movement of the drive plate 141 and support the cylinder 142, which is beneficial for a compact structure.

[0044] Please refer to Figure 2 Multiple grippers 12 are arranged around the cylinder 142 to ensure that each gripper 12 is subjected to balanced force.

[0045] Working principle of the gripper material handling drive mechanism in the preferred embodiment of this utility model: When it is necessary to release the material, the drive plate 141 moves from a high position to a low position, forcing the first arm 121 of each gripper 12 to rotate downwards simultaneously, thereby causing the second arm 122 of each gripper 12 to release the material simultaneously. At this time, multiple elastic elements 13 store energy simultaneously. When it is necessary to clamp the material, the drive plate 141 moves from a low position to a high position, and multiple elastic elements 13 release energy simultaneously. The elastic elements 13 provide elastic force to make the first arm 121 rotate upwards, thereby enabling the second arm 122 to clamp the material.

[0046] This is the working process of the gripper material gripping drive mechanism in this preferred embodiment.

[0047] The gripper material gripping drive mechanism of this utility model can simultaneously release the material piece through the drive plate, so as to avoid the material piece tilting and affecting subsequent operations.

[0048] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the concept of the technical solution of the present invention, should be included within the scope of protection of the present invention.
