[0002] On automated production lines in injection molding workshops, robotic arms for picking up materials for injection molding machines are often installed next to the mold opening and closing stations of the injection molding machine. They operate precisely in coordination with the injection cycle. After the mold is completed and opened, the robotic arm quickly extends into the mold cavity and uses customized grippers to stably grab the newly formed plastic parts (such as appliance shells, automotive parts, medical device components, etc.). Then, the products are transferred to the conveyor belt, inspection table, or stacking area according to the preset trajectory. At the same time, auxiliary operations such as waste material grabbing and sprue separation can be completed simultaneously.

[0003] However, the above-mentioned device still has the following problems during implementation:

[0004] Existing technology requires that the robotic arm of an injection molding machine needs to change different models of grippers in a timely manner when producing different plastic parts. However, the grippers are all installed by connecting them to the end of the robotic arm with bolts. When changing grippers, tools such as wrenches are needed to remove or install the bolts, which takes a long time for each change. Frequent changes in production will seriously delay the production cycle. Therefore, an auxiliary material handling device for injection molding machines is proposed to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide an auxiliary material handling device for injection molding machines, which has the advantage of quick gripper replacement. It solves the problem that gripper installation methods all use bolts to connect the gripper to the end of the robotic arm, requiring tools such as wrenches to remove or install bolts when replacing grippers, resulting in long replacement times and serious disruption to production cycle when frequently changing production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary material handling device for an injection molding machine, comprising a material handling robotic arm, two connecting blocks, two U-shaped shells, and a gripping plate, wherein the top of the connecting blocks is fixedly connected to the bottom of the material handling robotic arm, the U-shaped shells are fixedly connected to the surface of the connecting blocks, and the gripping plate is movably connected to the bottom of the connecting blocks;

[0028] Example 1

[0029] Reference Figure 1-4This is the first embodiment of the present invention, which provides an auxiliary material handling device for an injection molding machine, including a material handling robotic arm 1, two connecting blocks 2, two U-shaped shells 3 and a gripping plate 4. The top of the connecting blocks 2 is fixedly connected to the bottom of the material handling robotic arm 1, the U-shaped shells 3 are fixedly connected to the surface of the connecting blocks 2, and the gripping plate 4 is movably connected to the bottom of the connecting blocks 2.

[0030] The top of the gripper plate 4 is fixedly connected to the docking shell 5, and the inner cavity of the docking shell 5 is movably connected to the positioning component 6;

[0031] Linkage component 7 is located inside the U-shaped shell 3.

[0032] Specifically, after the gripper 4 docks with the connecting block 2, the positioning component 6 can fix the position of the docking shell 5, and the linkage component 7 can easily disassemble the docking shell 5.

[0033] Furthermore, when it is necessary to connect the gripper plate 4 to the connecting block 2, the gripper plate 4 is lifted to drive the docking shell 5 to connect with the docking groove 8 at the bottom of the connecting block 2.

[0034] Example 2

[0035] The second embodiment of this utility model provides an auxiliary material handling device for an injection molding machine. The bottom of the connecting block 2 is provided with a docking groove 8 that cooperates with the docking shell 5. The docking shell 5 is inserted into the inner cavity of the docking groove 8. The bottom of the inner cavity of the docking groove 8 is provided with a chamfer 9. The positioning component 6 includes two extrusion plates 61. Springs 62 are fixedly connected to the left and right sides of the opposite side of the two extrusion plates 61. Locking rods 63 are fixedly connected to the left and right sides of the opposite side of the two extrusion plates 61. The side of the U-shaped shell 3 and the docking groove 8 near the locking rods 63 is provided with a movable hole 10 that cooperates with the locking rods 63. The locking rods 63 are inserted into the inner cavity of the movable hole 10. The side of the two extrusion plates 61 opposite to each other is provided with a stroke hole 11. A stroke rod 12 is movably connected to the inner cavity of the stroke hole 11. The side of the stroke rod 12 near the inner wall of the docking shell 5 is fixedly connected to the inner wall of the docking shell 5.

[0036] Specifically, by setting the docking groove 8, chamfer 9, positioning component 6, movable hole 10, stroke hole 11, and stroke rod 12, the docking shell 5 can be positioned after being inserted into the docking groove 8. The chamfer 9 can easily squeeze the clamping rod 63 into the docking shell 5. The clamping rod 63 is inserted into the movable hole 10, which can also position the docking shell 5. The pressure of the spring 62 on the pressing plate 61 prevents the pressing plate 61 from driving the clamping rod 63 out of the movable hole 10. The stroke hole 11 and stroke rod 12 can control the movement position of the pressing plate 61.

[0037] Furthermore, when the docking slot 8 is inserted, the inclined surface on the locking rod 63 will press against the chamfer 9. This will cause the locking rod 63 to move and press against the pressing plate 61. The movement of the pressing plate 61 will press against the spring 62. When the docking shell 5 is fully inserted into the docking slot 8, the locking rod 63 will align with the movable hole 10. At this time, the spring 62 will undergo elastic deformation, causing the pressing plate 61 to return to its original position. The pressing plate 61 can then drive the locking rod 63 to be inserted into the movable hole 10.

[0038] Example 3

[0039] The third embodiment of this utility model provides an auxiliary material handling device for an injection molding machine. The inner cavity of the movable hole 10 is movably connected to a push rod 13 that works with a clamping rod 63. The front and rear sides of the inner cavity of the U-shaped shell 3 are movably connected to a control plate 14. The side of the push rod 13 closest to the control plate 14 is fixedly connected to the control plate 14. The linkage assembly 7 includes a linkage plate 71. The right side of the linkage plate 71 is fixedly connected to a control lever 72. The right side of the control lever 72 passes through the U-shaped shell 3 and extends to the outside of the U-shaped shell 3. The front and rear sides of the left side of the linkage plate 71 are rotatably connected to a rotating plate 73 via a rotating shaft. The left side of the rotating plate 73 is rotatably connected to the control plate 14 via a rotating shaft.

[0040] Specifically, by setting up push rod 13, control plate 14 and linkage component 7, when it is necessary to disassemble docking shell 5, push control lever 72 to drive two control plates 14 to squeeze push rod 13. The four push rods 13 can move the position of clamping rod 63, which serves to quickly disassemble clamping plate 4.

[0041] Furthermore, when it is necessary to disassemble the gripper plate 4, push the control lever 72 to move the linkage plate 71. The movement of the linkage plate 71 will cause the two rotating plates 73 to squeeze the two control plates 14 closer to each other. The movement of the control plates 14 will cause the push rod 13 to squeeze the push rod 13 in the movable hole 10. When the push rod 13 moves the locking rod 63 into the docking groove 8, the docking shell 5 can be separated from the docking groove 8.

[0042] Working principle:

[0043] When it is necessary to connect the gripper plate 4 to the connecting block 2, pick up the gripper plate 4 to drive the docking shell 5 to connect with the docking groove 8 at the bottom of the connecting block 2. When inserting into the docking groove 8, the inclined surface on the clamping rod 63 will press against the chamfer 9. At this time, the clamping rod 63 can be moved to press the pressing plate 61. The pressing plate 61 will press the spring 62. When the docking shell 5 is fully inserted into the docking groove 8, the clamping rod 63 will be aligned with the movable hole 10. At this time, the spring 62 will undergo elastic deformation to drive the pressing plate 61 back to its original position. The pressing plate 61 can then drive the clamping rod 63 to be inserted into the movable hole 10.

[0044] When it is necessary to disassemble the gripper plate 4, push the control lever 72 to move the linkage plate 71. The movement of the linkage plate 71 will cause the two rotating plates 73 to squeeze the two control plates 14 closer to each other. The movement of the control plates 14 will cause the push rod 13 to squeeze the push rod 13 in the movable hole 10. When the push rod 13 moves the locking rod 63 into the docking groove 8, the docking shell 5 can be separated from the docking groove 8.

[0045] In summary, the combination of the U-shaped shell 3, gripper plate 4, docking shell 5, positioning component 6, and linkage component 7 enables a quick gripper replacement.
