Description

Technical Field

[0001] This application relates to the field of automated injection molding equipment technology, and in particular to a robotic arm for sorting injection molded parts. Background Technology

[0002] In the flashlight manufacturing industry, the mass production of the front and back shells of flashlights mainly relies on injection molding. In this process, the subsequent sorting process has long been completed by manual operation or single-function robotic arms.

[0003] Existing solutions typically use parallel dual-suction cup robotic arms, which integrate two sets of independently controllable suction cups through a parallel mechanism to simultaneously grasp the front or rear shell of a flashlight part.

[0004] However, the existing technology has a drawback: the parallel dual-suction cup robot can only effectively handle flashlight parts of the same type, limited to the front or rear shell. The insufficient ability to process multiple types of injection molded parts simultaneously results in long cycle times and low sorting efficiency. Utility Model Content

[0005] To address the aforementioned problems, this application provides a robotic arm for sorting injection molded parts.

[0006] The injection molded part sorting robot provided in this application adopts the following technical solution:

[0007] A robotic arm for sorting injection molded parts includes a robotic arm, a support frame, a first suction component, a second suction component, and a clamping component. The first suction component and the clamping component are located in the middle of the support frame. The first suction component is used to uniformly suction multiple types of injection molded parts, and the clamping component is used to clamp injection molded part waste. The second suction component is located at the end of the support frame and is used to distinguish and suction injection molded parts of the same type.

[0008] By adopting the above technical solution, the injection molded part sorting robot is used to sort the injection molded front shell and outer shell of the flashlight, and at the same time separate the waste material. The robotic arm is used to provide support and motion trajectory so that the first suction component and the clamping component can simultaneously clamp the waste material and suck up the front shell and the rear shell. The clamping component first puts the waste material into the waste box, and then the first suction component releases the front shell and the rear shell onto the sorting worktable. The sorting component then puts the front shell and the rear shell into different types of storage boxes for sorting. This enhances the ability to process multiple types of injection molded parts simultaneously, reduces cycle time, and improves sorting efficiency.

[0009] Preferably, the first suction component includes a first suction cup and a first connecting tube. There are multiple first suction cups. The first suction cups are fixed and connected to the first connecting tube. The first connecting tube is connected to an external air supply device.

[0010] By adopting the above technical solution, the first suction cup is fixed and connected to the first connecting tube. The first connecting tube is connected to an external air supply device. During operation, the air supply device generates negative pressure to form a vacuum adsorption force on the contact surface between the first suction cup and the injection molded part, thereby achieving stable gripping.

[0011] Preferably, the support frame includes a first support rod and a second support rod. The first support rod is connected to the robotic arm. Several second support rods are provided. The second support rods are fixed to the first support rods and perpendicular to each other. A connecting component is provided between the second support rods and the first connecting pipe.

[0012] By adopting the above technical solution, the vertical fixing structure of the first and second support rods provides spatial guidance and motion direction constraints for the robotic arm's picking and sorting operations, and the connecting component connects the second support rod and the first connecting pipe.

[0013] Preferably, the connecting assembly includes a fastening screw and a fastening strip. The second support rod is provided with a second limiting groove, and the fastening strip is provided with a fastening groove. The fastening strip passes through the fastening groove and the second limiting groove via the fastening screw to achieve a fixed connection between the fastening strip and the second support rod. It can be tightened and fixed by the fastening screw. The surface of the fastening strip abuts against the surface of the second support rod. The fastening strip is detachable, and the first connecting tube is fixedly connected to the fastening strip.

[0014] By adopting the above technical solution, the fastening strip is screwed into the second limiting groove and the fastening groove, allowing the fastening strip to slide up and down along the fastening groove. Since the fastening strip is also fixedly connected to the first connecting tube, and the first connecting tube is fixedly connected to the first suction cup, the fastening strip can drive the first connecting tube and the first suction cup to slide up and down along the fastening groove. The fastening strip is detachable, thus allowing it to be adjusted to fit different injection molded parts. After the fastening screw is tightened, the position of the first connecting tube and the first suction cup can be fixed. Since the fastening strip is detachable, the first connecting tube and the first suction cup are also detachable, allowing the first connecting tube and the first suction cup to be fixed in different positions according to different injection molded part sizes.

[0015] Preferably, the second suction assembly includes a second suction cup and a second connecting tube. There are several second suction cups. The second suction cups are fixed and connected to the second connecting tube. The second connecting tube is connected to an external air supply device. The end of the first support rod away from the robotic arm is vertically fixed with a limiting seat. The limiting seat is provided with a first limiting groove. The second suction cup and the second connecting tube are fixedly connected to the first limiting groove through the connecting assembly. The second suction cup, the second connecting tube, and the limiting groove are fixedly connected through the fastening strip and the fastening screw.

[0016] By adopting the above technical solution, the second suction cup assembly is used to sort various types of injection molded parts. The second suction cup, the second connecting tube, and the limiting groove are fixedly connected by fastening strips and fastening screws. The fastening strip can slide up and down along the fastening groove. Since the fastening strip is also fixedly connected to the second connecting tube, and the second connecting tube is fixedly connected to the second suction cup, the fastening strip can drive the second connecting tube and the second suction cup to slide up and down along the fastening groove. This can adapt to the gripping needs of injection molded parts of different sizes. Since the fastening strip is detachable, the second connecting tube and the second suction cup are also detachable. The second connecting tube and the second suction cup can be fixed in different positions according to different injection molded part sizes.

[0017] Preferably, the clamping component is configured as a gripper cylinder, which is located in the middle of the first bearing rod and is fixedly connected to the first bearing rod.

[0018] By adopting the above technical solution, the gripper cylinder can hold the waste material, and the waste material can be placed into the waste material frame first, thus achieving physical isolation between the waste material and the injection molded part.

[0019] Preferably, both the first suction component and the second suction component are provided with air supply pipes. One end of the air supply pipe is connected to the first connecting pipe and the second connecting pipe, and the other end of the air supply pipe is connected to an air supply device. An injection molded part sorting robot also includes a pipe, and the air supply pipes are all placed inside the pipe. The pipe is fixed to the side wall of the robot arm.

[0020] By adopting the above technical solution, the gas supply pipes are scattered around the first and second support rods, which are prone to friction and entanglement. However, by centrally storing them inside the pipe, the contact between the gas supply pipes and the first and second support rods can be reduced, thus reducing interference with the movement trajectory of the first and second support rods.

[0021] Preferably, the robotic arm is equipped with a rotary joint, and the first support rod is rotatably connected to one end of the robotic arm through the rotary joint.

[0022] By adopting the above technical solution, the rotary joint increases the rotational freedom at the connection between the robotic arm and the first support rod, allowing the first support rod to flexibly adjust its direction according to the position of the injection molded part, thus adapting to grasping and sorting tasks in complex spaces.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The injection molded part sorting robot uses a robotic arm to provide support and movement trajectory so that the first suction component on the carrier can pick up multiple types of injection molded parts, the clamping component can hold waste materials, and the second suction component can sort multiple types of injection molded parts. This enables the simultaneous processing of multiple types of injection molded parts, shortens the cycle time, and improves sorting efficiency.

[0025] 2. The clamping component uses a gripper cylinder. The gripper cylinder clamps the waste material. The waste material can be placed into the waste material box first, and the waste material and the injection molded part are physically isolated.

[0026] 3. The second suction cup assembly is used to sort various types of injection molded parts. The second suction assembly is connected to the limiting seat through the connecting assembly. The connecting assembly is detachable, so as to flexibly adapt to the sorting needs of injection molded parts of different sizes. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a robotic arm for sorting injection molded parts. (Refer to...) Figure 1 A sorting robot for injection molded parts includes a robotic arm 1, a support frame 2, a first suction component 4, a second suction component 5, and a clamping component 10. The first suction component 4 and the clamping component 10 are located in the middle of the support frame 2. The first suction component 4 is used to uniformly suction multiple types of injection molded parts, and the clamping component 10 is used to clamp injection molded part waste. The second suction component 5 is located at the end of the support frame 2 and is used to distinguish and suction injection molded parts of the same type.

[0034] This demonstrates that the injection-molded part sorting robot is used to sort the injection-molded front and outer shells of flashlights and simultaneously separate waste materials. The robotic arm 1 provides support and a movement trajectory so that the first suction component 4 and the clamping component 10 can simultaneously clamp the waste materials and suck up the front and rear shells of the flashlights. The clamping component 10 first puts the waste materials into the waste box, and then the first suction component 4 releases the front and rear shells of the flashlights onto the sorting worktable. The sorting component then puts the front and rear shells into different types of storage boxes for sorting, which enhances the ability to process multiple types of injection-molded parts simultaneously, reduces cycle time, and improves sorting efficiency.

[0035] Reference Figure 2 Correspondingly, the support frame 2 includes a first support rod 21 and a second support rod 22. The second support rod 22 is provided with several rods, and the second support rod 22 is fixedly connected to the first support rod 21 and perpendicular to each other.

[0036] Specifically, each component is described in detail according to the movement sequence of this embodiment. There are two second bearing rods 22. Both second bearing rods 22 are long strip-shaped structures. The two second bearing rods 22 are fixed to the first bearing rod 21 by bolts. The two first bearing rods 21 are parallel to each other and separated by a distance.

[0037] Correspondingly, the robotic arm 1 is equipped with a rotary joint 9, and the first bearing rod 21 is rotatably connected to one end of the robotic arm 1 through the rotary joint 9.

[0038] On the other hand, the first suction component 4 is correspondingly disposed on the second support rod 22, and the number of the first suction components 4 is set according to the number of injection molded parts that need to be suctioned at one time. In this embodiment, the first suction component 4 needs to suction four injection molded parts at one time, including two front shells and two rear shells of the flashlight. The number of the first suction components 4 is set to four sets, and the four sets of first suction components 4 are divided into two groups and symmetrically installed on two second support rods 22. Two sets are fixed on each second support rod 22. The two sets of first suction components 4 fixed on the same second support rod 22 are respectively disposed at both ends of the second support rod 22 with the first support rod 21 as the axis. The four sets of first suction components 4 are parallel to each other in the horizontal and vertical directions.

[0039] Correspondingly, the first suction component 4 includes a first suction cup 41 and a first connecting tube 42. The first suction cup 41 is fixedly connected to and communicates with the first connecting tube 42. The first connecting tube 42 is connected to the second bearing rod 22 through a connecting component 6. The connecting component 6 includes a fastening screw 62 and a fastening strip 61.

[0040] Specifically, the second support rod 22 is provided with a second limiting groove 221, which penetrates through the left and right side walls of the second support rod 22. The fastening strip 61 is provided with a fastening groove 611, which penetrates through the fastening strip 61. The fastening strip 61 is inserted into the fastening groove 611 and the second limiting groove 221 by a fastening screw 62, thereby achieving a fixed connection between the fastening strip 61 and the second support rod 22. It can be tightened and fixed by the fastening screw 62. The lower surface of the nut of the fastening screw 62 abuts against the upper surface of the fastening strip 61, and the lower surface of the fastening strip 61 abuts against the side surface of the second support rod 22 away from the first support rod 21. The fastening strip 61 can slide along the fastening groove 611 and is detachable. The first connecting tube 42 is fixedly connected to the fastening strip 61. Since the first suction cup 41 is fixedly connected to and communicates with the first connecting tube 42, the first suction cup 41 and the first connecting tube 42 are also detachable.

[0041] In addition, the first suction component 4 is provided with an air supply pipe 7, one end of which is fixedly connected to the other end of the first connecting pipe 42, and the other end of which is connected to the air supply equipment.

[0042] In addition, the clamping component 10 is configured as a gripper cylinder, which is located between the two second bearing rods 22 and fixed on the first bearing rod 21. While the first suction cup 41 picks up the injection molded part, the gripper cylinder picks up the waste material.

[0043] This explains that when the injection molding part sorting robot starts working, the four first suction cups 41 remove the two front shells and two rear shells of the injection molded flashlight from the injection mold. Through the external air supply equipment, the air supply equipment generates negative pressure, which makes the first suction cups 41 form a vacuum suction force with the two front shells and two rear shells of the flashlight, thus achieving stable gripping. At the same time, the gripper cylinders pick up the produced waste material. The injection molding part sorting robot first puts the waste material into the waste material box, and the waste material is physically isolated from the two front shells and two rear shells of the flashlight. Then, the two front shells and two rear shells of the flashlight are placed into the sorting worktable.

[0044] Reference Figure 3 On the other hand, the end of the first bearing rod 21 away from the robotic arm 1 is vertically fixed to the limiting seat 3. In this embodiment, the second suction component 5 is provided in two sets. The second suction component 5 is also connected and fixedly connected to the limiting seat 3 by fastening strip 61 and fastening screw 62.

[0045] The second suction assembly 5 includes a second suction cup 51 and a second connecting tube 52. The second suction cup 51 is fixed and connected to one end of the second connecting tube 52. The limiting seat 3 is provided with a first limiting groove 31. The fastening strip 61 is inserted into the fastening groove 611 and the first limiting groove 31 through the fastening screw 62, so as to realize the fixed connection between the fastening strip 61 and the limiting seat 3. It can be tightened and fixed by the fastening screw 62. The lower surface of the nut of the fastening screw 62 abuts against the upper surface of the fastening strip 61. The lower surface of the fastening strip 61 abuts against the side surface of the limiting seat 3 away from the first bearing rod 21. The second connecting tube 52 is fixedly connected to the fastening strip 61. Since the fastening strip 61 is detachable, the second connecting tube 52 and the second suction cup 51 are also detachable.

[0046] In addition, the second suction assembly 5 is also provided with an air supply pipe 7. One end of the air supply pipe 7 is fixedly connected to the other end of the second connecting pipe 52, and the other end of the air supply pipe 7 is connected to the air supply equipment.

[0047] This illustrates that when the first suction component 4 physically isolates the waste from the two front and two rear shells of the flashlight and places the two front and two rear shells of the flashlight into the sorting workbench, the second suction component 5 sorts the two front and two rear shells of the flashlight separately. One second suction cup 51 first picks up the front shell of one flashlight, and the other second suction cup 51 picks up the front shell of the other flashlight. Then, the two front shells of the flashlight are placed into the storage box, and the two rear shells of the flashlight are placed into another storage box using the same method, thus realizing the sorting of the two front and two rear shells of the flashlight.

[0048] Reference Figure 4 On the other hand, the injection molding part sorting robot also includes a pipe 8. The air supply pipe 7 of the first suction component 4 and the air supply pipe 7 of the second suction component 5 are both placed inside the pipe 8. The pipe 8 is fixed on the side wall of the robot arm 1. The air supply pipes 7 are scattered around the first support rod 21 and the second support rod 22, which are prone to friction and entanglement. Concentrating them in the pipe 8 can reduce the contact between the air supply pipes 7 and the first support rod 21 and the second support rod 22, and reduce the interference with the movement trajectory of the first support rod 21 and the second support rod 22.

[0049] The implementation principle of a sorting robot for injection molded parts according to an embodiment of this application is as follows:

The fastening strip is fixed in the second limiting groove of the second support rod by fastening screws. The fastening strip can slide up and down along the fastening groove and is detachable. The first connecting tube is fixedly connected to the fastening strip. Since the first suction cup is fixedly connected to and connected to the first connecting tube, the first suction cup and the first connecting tube are also detachable.

[0053] A limiting seat is provided at the end of the first support rod away from the robotic arm. The second suction component is also fixedly connected to the limiting seat through a connecting component. The second suction component includes a second suction cup and a second connecting tube. The limiting seat is provided with a first limiting groove. The fastening strip is inserted into the fastening groove and fixed in the first limiting groove of the limiting seat by fastening screws. The fastening strip can slide up and down along the fastening groove and is detachable. The second connecting tube is fixedly connected to the fastening strip. Since the second suction cup is fixedly connected to and communicates with the second connecting tube, the second suction cup and the second connecting tube are also detachable.

[0054] The injection molded parts sorting robot begins its work. The first suction cups of the four first suction components pick up the two front shells and two rear shells of the flashlight from the injection mold at once. At the same time, the gripper cylinders pick up the waste material and transport it to the top of the waste material box. The gripper cylinders release the waste material first to ensure that the waste material is physically separated from the injection molded parts. The first suction cups release the front shells and rear shells of the flashlight to the sorting worktable. The second suction cups of the two second suction components pick up the two front shells and two rear shells in turn and put the front shells and rear shells into the corresponding storage boxes, realizing the precise sorting of multiple types of injection molded parts.

[0055] In addition, both the first and second connecting pipes are externally connected to air supply equipment. The first and second connecting pipes are connected to the air supply equipment through air supply pipes. The injection molding part sorting robot also includes pipes, and the air supply pipes are placed inside the pipes. The pipes are fixed to the side wall of the robot arm.
