[0022] according to Figures 1 to 8 The utility model discloses a tweezers automatic fork splitting shaping grasping and releasing device, comprising a frame 1, a packaging discharging conveyor belt 2 fixed on the frame 1, a tweezers feeding frame 3 located at one side of the packaging discharging conveyor belt 2, a fork assembly 4, and a manipulator assembly 5.

[0023] The tweezers feeding rack 3 includes a fork frame 6, a lifting cylinder 7, a sensor 8 and a positioning cylinder 9. The fork frame 6 consists of two vertical support arms 10 and a fork frame base plate 11. The lower ends of the vertical support arms 10 are respectively fixed on both sides of the fork frame base plate 11. A tweezers groove 12 is provided on the top of the vertical support arm 10. The side shape of the tweezers groove 12 is a triangle with the top angle facing downward. The two ends of the tweezers 13 are respectively located in the tweezers grooves 12 of the two vertical support arms 10, and the two clamping arm surfaces of the tweezers 13 are against the side walls of the tweezers groove 12. The fork frame bottom plate 11 of the fork frame 6 is connected to the output end of the lifting cylinder 7, and the lifting cylinder 7 is fixed on the frame 1. The lifting cylinder 7 vertically pushes the fork frame 6 up and down to facilitate the fork frame 6 to feed and vertically position the height of the tweezers 3; the sensor 8 is arranged on one side of the vertical support arm 10 through the fixed bracket 14, and the vertical support arm 10 does not contact the fixed bracket 14 and the sensor 8. The positioning cylinder 9 is arranged on one side of the other vertical support arm 10. The output end of the positioning cylinder 9 is provided with a push plate 15, and the push plate 15 is located on one side of the tweezers groove 12, which is used to push the tweezers 13 into place laterally; the positioning cylinder 9 and the push plate 15 do not contact the fork frame 6. The direction of the tweezers 13 is controlled by the worker who discharges the materials. When discharging the materials, the materials are uniformly discharged in the required direction, and the subsequent tweezers will not change direction due to the action of the mechanical structure. In the utility model, the forceps 13 can enter the fork frame 6 by being placed manually, or by a forceps pushing device to push the forceps 13 into the fork frame 6 .

[0024] The upper end of the forked component 4 is arranged above the tweezers feeding rack 3 through the connecting crossbar 16, and the forked component 4 includes a forked cylinder 17, a forked knife 18, a shaping cylinder 19, a shaping plate 20, a forked backer 21, a forked bottom plate 22 and a connecting block 25. The upper end of the forked cylinder 17 is connected to the connecting crossbar 16; the output end of the forked cylinder 17 is connected to one end of the top surface of the forked bottom plate 22 through a folding plate 23; during the movement, the forked cylinder 17 can push the folding plate 23 laterally, and then the folding plate 23 drives the forked bottom plate 22 to move laterally, so that the forked bottom plate 22 and the components connected to the forked bottom plate 22 are pushed laterally together. The upper end of the forked knife 18 is connected to the bifurcated bottom plate 22 by screws. The forked knife 18 is fixed to one end of the bottom surface of the bifurcated bottom plate 22. The cross section of the forked knife 18 is shuttle-shaped. A positioning pin 24 is provided in the middle of the bottom surface of the forked knife 18. One shaping plate 20 is provided on each side of the bifurcated backrest 21. The bifurcated backrest 21 is fixed to the other end of the bottom surface of the bifurcated bottom plate 22. The cross section of the bifurcated backrest 21 is an isosceles trapezoid. The shorter upper bottom of the isosceles trapezoid is aligned with the forked knife 18, and the two bottom corners of the isosceles trapezoid are aligned with the two shaping plates 20 located on both sides of the bifurcated backrest 21. The two shaping plates 20 are respectively connected to the output end of the shaping cylinder 19 through the connecting block 25, and the shaping cylinder 19 is fixed to the top surface of the bifurcated bottom plate 22. The bifurcated knife 18 is located at a side close to the tail end of the tweezers 13, and the bifurcated backer 21 is located at a side close to the head end of the tweezers 13, and the head end of the tweezers 13 is the bifurcated end.

[0025] When the tweezers 13 are lifted by the manipulator assembly 5, and the split fork knife 18 is inserted between the two clamping arms of the tweezers 13, the bifurcated cylinder 17 drives the folding plate 23 and the bifurcated bottom plate 22 to move horizontally, and the bifurcated knife 18, the shaping cylinder 19, and the bifurcated backing 21 connected to the bifurcated bottom plate 22 are moved toward the tail end of the tweezers 13, wherein the bifurcated knife 18 is further inserted into the inner side of the tweezers 13, so that the bifurcated angle of the tweezers 13 becomes larger, and at the same time, the head end of the tweezers 13 also hits the shaping plate 20 to form a limit. Then the shaping cylinder 19 pushes the shaping plate 20 inward, and the inner side of the bending position of the head end of the tweezers 13 is against the outer side of the bifurcated backing 21 to achieve the limit, and the head end of the tweezers 13 is retracted inward by the shaping plate 20, completing the shaping of the head of the tweezers 13.

[0026] The manipulator assembly 5 includes a rodless cylinder 26, a lifting cylinder 27, a clamping cylinder 28 and a clamping plate 29. The rodless cylinder 26 is arranged on one side of the connecting crossbar 16. The connecting crossbar 16 and the rodless cylinder 26 cross the packaging discharge conveyor belt 2. The upper end of the lifting cylinder 27 is connected to the output end of the rodless cylinder 26, and the lower end of the lifting cylinder 27 is connected to the clamping cylinder 28. The clamping plate 29 is arranged on the output end of the clamping cylinder 28; the clamping plate 29 is located on one side of the forked knife 18. The clamping position of the clamping plate 29 is aligned with the tail end of the tweezers 13. When in operation, the clamping plate 29 clamps the tail end of the tweezers 23, and no obvious displacement occurs in the subsequent actions.

[0027] The driving control principle of each cylinder and the signal transmission of the sensor of the utility model are existing technologies in the field of numerical control equipment, and the utility model will not elaborate on them.

[0028] The working process of this utility model is as follows:

[0029] The fork frame 6 of the tweezers feeding frame 3 is used to place the tweezers 13 to be forked; the sensor 8 detects whether there are tweezers 13 in the fork frame 6. When the sensor 8 detects the presence of tweezers, the positioning cylinder 9 pushes the tweezers 13 to the left, that is, in the direction of the clamping plate 29, so that the tweezers 13 are positioned to the preparatory position, preparing for the clamping plate 29 to clamp the tail end of the tweezers 23. Then, the lifting cylinder 7 drives the fork frame 6 to be raised until the tip of the positioning needle 24 of the fork knife 18 is inserted in the middle of the tweezers 13, achieving preliminary positioning.

[0030] The lifting cylinder 27 in the manipulator assembly 5 first descends so that the position of the clamping plate 29 is just in the position to clamp the tweezers 13. The clamping cylinder 28 drives the clamping plate 29 to clamp the root, i.e., the tail end, of the tweezers 13. Then the lifting cylinder 27 is lifted upward to clamp the fork knife 18 in the middle of the tweezers 13.

[0031] The forked cylinder 17 in the forked assembly 4 drives the forked knife 18 to push toward the tail end of the tweezers 13, so that the tweezers 13 are completely forked, and the shaping cylinder 19 then drives the shaping plate 20 inward to clamp the head of the tweezers 13 on the forked backing 21, bending the head of the tweezers 13 inward for shaping, and then the shaping cylinder 19 is released.

[0032] The rodless cylinder 26 of the manipulator assembly 5 drives the entire manipulator assembly 5 to pull the tweezers 13 away from the fork assembly 4 and stop it above the packaging box 30 on the packaging discharge conveyor belt 2. Then the clamping cylinder 28 of the manipulator assembly 5 drives the clamping plate 29 to release the tweezers 13, so that the tweezers 13 fall into the packaging box 30. Finally, the rodless cylinder 26 drives the manipulator assembly 5 back to the initial position, ending the whole set of operating actions.
