[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] like Figures 1 to 9 As shown in this embodiment, a material positioning and flipping assembly for a stacked rack includes a receiving support rod 1, a front positioning structure 2, a rear positioning structure 3, and a flipping robot 4. The front positioning structure 2 and the rear positioning structure 3 are located at the two ends of the receiving support rod 1, respectively. The flipping robot 4 is installed between the front positioning structure 2 and the rear positioning structure 3. The flipping robot 4 flips and transfers the material between the front positioning structure 2 and the rear positioning structure 3. Signal sensors 5 are installed on both sides of the receiving support rod 1.
[0030] The material on the front material column is placed into the front positioning structure 2 for positioning. Then, the flipping robot 4, located on the edge of the front positioning structure 2, clamps the sprue frame of the positioned material and flips it into the rear positioning structure 3 for another flipping and positioning. After the material in the rear positioning structure 3 is released, the signal sensor 5 senses the signal and transmits it to the robot of the injection molding machine to grab it and put it into the injection molding machine for injection molding. Then, the material after injection molding is grabbed and returned to the rear positioning structure 3 for positioning. The flipping robot 4 comes again to grab the material in the rear positioning structure 3 and flip it back to the front positioning structure 2. The transverse structure grabs the material that has been injected in the front positioning structure 2 and stores it in the material column for unloading, waiting to be transferred to the injection molding structure of the next color.
[0031] Specifically, the front positioning structure 2 includes a first receiving base plate 6, a first receiving middle plate 7 and a first receiving top plate 8. The front end of the first receiving base plate 6 is locked with a first connecting post 9. The front end of the first receiving middle plate 7 is provided with a first angle adjustment groove 10. The first connecting post 9 passes vertically upward through the first angle adjustment groove 10 and is connected to a first connecting screw 11.
[0032] The first receiving plate 7 is equipped with first receiving connecting posts 12 around its perimeter. The upper end of the first receiving connecting posts 12 is locked onto the first receiving top plate 8. The first receiving top plate 8 is provided with a first receiving cavity 13 in the middle. A first receiving positioning ring 14 is snapped into the first receiving cavity 13. Several receiving positioning holes 15 are distributed on the first receiving positioning ring 14.
[0033] The outer side of the first receiving positioning ring 14 is integrally formed with a first receiving protrusion 16, and the first receiving cavity 13 is provided with a first receiving groove 17, and the first receiving protrusion 16 and the first receiving groove 17 are connected.
[0034] The material grabbed from the material column is placed into the first receiving chamber 13. The positioning protrusion on the material is inserted downward into the receiving positioning hole 15, so that the current position of the material is positioned in the first receiving positioning ring 14, which facilitates accurate flipping and transfer into the injection molding machine. The first receiving connecting column 12 raises the first receiving top plate 8 to provide space for the flipping structure to grab. According to the mold position in the injection molding machine, the position of the first receiving groove 17 corresponding to the first receiving protrusion 16 can be changed, thereby changing the placement angle of the material. According to the material stacking on the material column, corresponding to the positioning protrusion position of the material, the first connecting screw 11 is loosened, so that the first connecting column 9 can be offset within the first angle adjustment groove 10. After meeting the corresponding requirements, the first connecting screw 11 is tightened to lock the current position and receive the material transferred from the material column.
[0035] Specifically, the rear positioning structure 3 includes a second receiving base plate 18, a second receiving middle plate 19, and a second receiving top plate 20. The rear end of the second receiving base plate 18 is locked with a second connecting post 21, and the front end of the second receiving middle plate 19 is provided with a second angle adjustment groove 22. The second connecting post 21 passes vertically upward through the second angle adjustment groove 22 and is connected to a second connecting screw 23.
[0036] The second receiving plate 19 is equipped with second receiving connecting columns 24 around its perimeter. The upper end of the second receiving connecting column 24 is locked onto the second receiving top plate 20. The second receiving top plate 20 is provided with a second receiving cavity 25 in the middle. A second receiving positioning ring 26 is snapped into the second receiving cavity 25. Several receiving positioning protrusions are distributed on the second receiving positioning ring 26.
[0037] The outer side of the second receiving positioning ring 26 is integrally formed with a second receiving protrusion 28, and the second receiving cavity 25 is provided with a second receiving groove 29, and the second receiving protrusion 28 and the second receiving groove 29 are connected.
[0038] After the material is injected from the injection molding machine, it is picked up by the robotic arm and placed into the second receiving chamber 25. The positioning protrusion on the material faces upward, and the receiving positioning protrusion is inserted below the positioning protrusion, so that the current position of the material is positioned in the second receiving positioning ring 26, which facilitates the subsequent accurate flipping and removal into the material column. The second receiving connecting column 24 raises the second receiving top plate 20 to provide space for the flipping structure to grab. According to the previous mold position in the injection molding machine, the position of the second receiving groove 29 corresponding to the second receiving protrusion 28 can be changed, thereby changing the placement angle of the material. According to the material stacking on the material column, corresponding to the positioning protrusion position of the material, the first connecting screw 11 is loosened, so that the first connecting column 9 can be offset within the first angle adjustment groove 10. After meeting the corresponding requirements, the first connecting screw 11 is tightened to lock the current position and receive the material transferred from the material column.
[0039] Specifically, the flipping robot 4 includes a rotary cylinder 30, a flipping square tube 31, a clamping arc plate 32, and several material grippers 33. One end of the flipping square tube 31 is connected to the drive end of the rotary cylinder 30, and the other end of the flipping square tube 31 is connected to the middle of the clamping arc plate 32. Several gripper mounting grooves 34 are provided on the clamping arc plate 32. The fixed ends of the material grippers 33 pass through the gripper mounting grooves 34 and are fixedly connected to the clamping arc plate 32.
[0040] A pneumatic connector 35 is installed on the fixed end of the material gripper 33. A gripper air pipe 36 is connected to the pneumatic connector 35. An air pipe connection hole 37 is provided on the clamping arc plate 32. The gripper air pipe 36 passes through the air pipe connection hole 37.
[0041] Position the clamping arc plate 32 on one side of the positioning structure, open the material gripper 33. When the material falls onto the positioning structure for positioning, the material's sprue frame is ready to fall into the open material gripper 33. When the material gripper 33 closes, it clamps the material's sprue frame. The rotary cylinder 30, connected by the flipping square tube 31, drives the entire clamping arc plate 32 to flip to the other side of the positioning structure, so that the material is positioned within the current positioning structure. At this time, open the material gripper 33 again to release the material. External gas is delivered through the gripper air pipe 36 to control the opening and closing of the material gripper 33. When the gripper air pipe 36 passes through the air pipe connection hole 37, it ensures that the gripper air pipe 36 is not placed haphazardly.
[0042] Specifically, sensor adjustment plates 38 extend outward from both sides of the receiving support rod 1. Sensor mounting holes 39 are provided on the sensor adjustment plates 38 along the vertical direction, and the end of the signal sensor 5 is locked in the sensor mounting hole 39.
[0043] With the help of signal sensor 5, the entry and exit of materials are automatically connected and transferred automatically without human intervention.
[0044] It should be stated that the above specific embodiments are merely preferred embodiments of the present invention and the technical principles applied thereto. Within the scope of the technology disclosed in the present invention, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of the present invention.
