DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to make the objects, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0018] Please refer to Figures 1-4, the present invention provides a fully automatic robotic arm shearing device, including a housing 3. A rear cover assembly is fixedly arranged on the back of the housing 3. A cylinder 1 is fixedly installed in the middle of the rear cover assembly. Two valve cores 2 are fixedly installed on one side of the cylinder 1. A cutting assembly for shearing workpieces is fixedly installed on the back of the cylinder 1. A connecting assembly is fixedly installed at the bottom of the housing 3. Block assemblies for assisting shearing are arranged on both sides of the inner wall of the housing 3.

[0019] Refer to Figure 1 , Figure 2 and Figure 4 , the rear cover assembly includes a bottom plate cover 4. Third locking pins 13 are arranged at the four corners of the bottom plate cover 4. The bottom plate cover 4 is fixedly arranged on the housing 3 through the four third locking pins 13. A first locking pin 10 is threadedly connected to the middle of the bottom plate cover 4. The cylinder 1 is fixedly arranged on the bottom plate cover 4 through the first locking pin 10. A reserved groove 11 is formed on one side of the back of the bottom plate cover 4. One end of the valve core 2 extends into the interior of the reserved groove 11;

[0020] The telescopic end of the cylinder 1 is fixedly installed on the bottom plate cover 4. The gas source device is fixedly connected to the valve core 2 through a hose. During operation, the cylinder 1 pushes the bottom plate cover 4 to move backward, drives the housing 3 to move backward through the bottom plate cover 4, and then squeezes the cutting assembly through the two block assemblies, thereby completing the shearing of the ABS label sprue.

[0021] Refer to Figure 1 , Figure 3 and Figure 4 , the cutting assembly includes a connecting bracket 8. One end of the connecting bracket 8 is fixedly arranged on the cylinder 1 through a screw. A fourth locking pin 15 is arranged at the other end of the connecting bracket 8. A diagonal cutting pliers body 9 is fixedly installed in the middle of the connecting bracket 8 through the fourth locking pin 15. Both block assemblies include bearings 6. Long locking columns 5 are arranged on the bearings 6. Two retaining sleeves 7 are rotatably connected to the surface of the long locking columns 5. The retaining sleeves 7 are arranged on both sides of the diagonal cutting pliers body 9; the connecting assembly includes a fixing plate 14. A second locking pin 12 is threadedly connected to the surface of the fixing plate 14. The fixing plate 14 is fixedly installed at the bottom of the connecting bracket 8 through the second locking pin 12;

[0022] Screw holes are reserved on the front of the fixing plate 14. During installation, the fixing plate 14 is directly locked on the shearing workbench with screws. During the entire shearing process, the positions of the connecting bracket 8, the diagonal cutting pliers body 9, and the fixing plate 14 remain unchanged. By moving the housing 3, the retaining sleeve 7 is driven to move, and the handle of the diagonal cutting pliers body 9 is squeezed through the retaining sleeve 7, thereby completing the shearing of the workpiece.

[0023] When the embodiment of the present application is in use: The robotic arm feeds the injection-molded and cooled ABS nameplate to the shearing workbench, places the nameplate sprue at the shearing end of the diagonal pliers body 9, and then the cylinder 1 extends to push the bottom plate cover 4 to move. By driving the bottom plate cover 4, the outer shell 3 moves backward. When the outer shell 3 moves, the two retaining sleeves 7 are driven to move through the long locking post 5. The retaining sleeves 7 squeeze the handle of the diagonal pliers body 9, thereby completing the shearing of the workpiece. After the shearing is completed, the cylinder 1 resets. At this time, the diagonal pliers body 9 returns to the initial state, and the next shearing work can be carried out. By using the pneumatic method for fully automatic shearing, it can not only significantly improve the shearing efficiency of the nameplate sprue, but also ensure that the cutting positions are consistent and more accurate. It has the characteristics of simple structure, safety, high efficiency, and convenient later maintenance.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
