Description

Technical Field

[0001] This utility model relates to the field of silicone soft clamp technology, specifically a silicone soft clamp for separating workpiece structures. Background Technology

[0002] This silicone soft clamp workpiece separation system consists of a pneumatic mechanical finger, a silicone soft clamp, a splash guard, a robotic arm, a workpiece bucket, and a sprue bag. During operation, the pneumatic finger removes the injection molded part from the mold and enters the splash guard together with the silicone soft clamp. The robotic arm drives the pneumatic finger to move up and down at high frequency. Utilizing the high elasticity and anti-slip design of the silicone soft clamp, the workpiece is separated from the sprue through dynamic friction. The separated workpiece falls into the workpiece bucket, while the pneumatic finger carries the sprue to the top of the bag for release. The system adopts a fully enclosed splash-proof design and, with precise PLC control of motion parameters, achieves a high efficiency of 10 separations per minute, with a workpiece damage rate of less than 0.5%, significantly improving production efficiency and yield.

[0003] In existing technologies, silicone soft clamps only perform reciprocating motion, resulting in a single mode of contact with the workpiece. During separation, uneven local force can easily lead to residual adhesion of complex-shaped workpieces, resulting in incomplete separation. Furthermore, the soft clamps experience severe local wear due to long-term unidirectional friction, affecting their service life. The anti-splash cover lacks a top airflow design, causing fine workpiece fragments and sprue particles generated during separation to splash disorderly inside the cover, easily contaminating critical components such as the soft clamps and mechanical fingers. Therefore, we need a silicone soft clamp for separating workpiece structures. Utility Model Content

[0004] The purpose of this invention is to provide a silicone soft clamp for separating workpiece structures, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A silicone soft clamp for separating workpiece structures includes a robotic arm. A first positioning post is fixedly connected to one side of the robotic arm, and a first sliding post is slidably connected to one side of the first positioning post. A mechanical finger is fixedly connected to the bottom of the first sliding post. A second positioning post is fixedly connected to one side of the robotic arm, and a second sliding post is slidably connected to one side of the second positioning post. An adjustment component is provided on one side of the second sliding post. A splash guard is provided on one side of the robotic arm, and a support frame is fixedly connected to the bottom of the splash guard. A mechanical finger is fixedly connected to one side of the support frame. The device includes an airflow assembly, a workpiece bucket at the bottom of the splash guard, and an adjustment assembly including a fixing plate fixed to one side of a second sliding column. A connecting rod is rotatably connected inside the fixing plate. One end of the connecting rod is fixedly connected to a silicone clamp, and the other end of the silicone clamp is fixedly connected to a gear. A rack is meshed with the outer wall of the gear, and a threaded sleeve is fixedly connected to one side of the rack. A threaded rod is threadedly connected to the inner wall of the threaded sleeve. One end of the threaded rod is fixedly connected to a coupling on a motor, and the other end of the threaded rod is rotatably connected to a fixing block. A support plate is fixedly connected to one side of the fixing block.

[0006] Preferably, the gear forms a rotating structure with the silicone soft clamp via a connecting rod, and one end of the connecting rod is connected to one side of the silicone soft clamp, and the outer wall of the connecting rod is connected to the inside of the gear.

[0007] Preferably, the motor forms a threaded structure through a threaded rod and a threaded sleeve, with one end of the threaded rod threaded through the threaded sleeve for connection, and the other end of the threaded rod connected to the output end of the motor.

[0008] Preferably, the threaded sleeve is linked to a gear via a rack and a gear, with one side of the rack connected to one side of the threaded sleeve and the other side of the rack meshing with the outer wall of the gear.

[0009] Preferably, the airflow assembly includes an air pump, which is fixed to one side of the support frame. An air inlet pipe is provided on the top of the air pump, and an air outlet pipe is provided on the top of the air pump. A support rod is fixedly connected to one side of the air outlet pipe, and a jet nozzle is sleeved on one end of the air outlet pipe.

[0010] Preferably, the air outlet pipe and the air nozzle form a fixed structure, and there are three air nozzles on the air outlet pipe, and all the air nozzles are located at the port of the air outlet pipe.

[0011] Preferably, the air pump is provided with an air inlet pipe and an air outlet pipe, and the air inlet pipe can input airflow and the air outlet pipe can output airflow. The air pump is connected to the jet nozzle through the air outlet pipe, and the air outlet pipe is located on the top of the air pump. The top of the jet nozzle is connected to the other end of the air outlet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. To address the limitations of existing silicone clamps that only perform reciprocating motion and have a single contact method with the workpiece, this application employs a robotic arm-driven dual-positioning column for coordinated positioning. This ensures the silicone clamp accurately enters the splash guard, preventing operational deviations. The design of the second sliding column sliding along the positioning column allows the fixing plate to flexibly adjust the working depth to accommodate workpieces of different sizes. A motor-driven threaded rod rotates, and through a threaded sleeve and rack transmission, the silicone clamp achieves 360° rotational separation, enabling adaptability to workpieces with complex shapes. The entire process is completed within the splash guard, and the rotational motion further reduces the risk of workpiece splashing, ensuring a clean working environment and operational safety. 2. To address the issue of workpiece splashing after separation in existing technologies, this application utilizes a first sliding column that slides precisely along a first positioning column, allowing the robotic finger to flexibly adjust its gripping position and ensure stable contact with the workpiece. The reciprocating motion of the robotic finger, combined with the elastic support of the silicone soft clamp, achieves non-destructive separation of the workpiece from the injection-molded part through dynamic friction. An airflow system driven by an air pump forms a directional airflow within the anti-splash cover via a jet nozzle, causing the separated workpiece to fall into the workpiece bin. This avoids the risk of secondary contamination from manual handling and further suppresses debris splashing through airflow impact. Combined with the enclosed structure of the cover, this provides double protection, ensuring operator safety and long-term equipment stability. Attached Figure Description

A workpiece barrel 11 is provided. The adjusting assembly 7 includes a fixed plate 701, which is fixed to one side of the second sliding column 6. A connecting rod 702 is rotatably connected inside the fixed plate 701. A silicone soft clamp 703 is fixedly connected to one end of the connecting rod 702. A gear 704 is fixedly connected to the other end of the silicone soft clamp 703. A rack 705 is meshed with the outer wall of the gear 704. A threaded sleeve 706 is fixedly connected to one side of the rack 705. A threaded rod 707 is threadedly connected to the inner wall of the threaded sleeve 706. One end of the threaded rod 707 is fixedly connected to a motor 708. The coupling has a threaded rod 707 with a fixed block 709 rotatably connected to the other end. A support plate 710 is fixedly connected to one side of the fixed block 709. First, by activating the robotic arm 1, the robotic arm 1 can move the first positioning post 2, which in turn can move the second positioning post 5, positioning the first and second positioning posts 2 and 5 above the splash guard 8. By activating the second sliding post 6, the second sliding post 6 can slide along the second positioning post 5, moving inside the splash guard 8 and moving the fixed block 709. The fixed plate 701 moves, and by starting the motor 708, the motor 708 drives the threaded rod 707 to rotate, which in turn rotates inside the threaded sleeve 706, causing the threaded sleeve 706 to move. The threaded sleeve 706 then drives the rack 705 to move, which in turn drives the gear 704 to rotate, which in turn drives the connecting rod 702 to rotate. The connecting rod 702 then rotates inside the fixed plate 701, which in turn drives the silicone soft clamp 703 to rotate.

[0017] Furthermore, such as Figure 3 As shown, the gear 704 forms a rotating structure with the silicone soft clamp 703 via the connecting rod 702. One end of the connecting rod 702 is connected to one side of the silicone soft clamp 703, and the outer wall of the connecting rod 702 is connected to the inside of the gear 704. Through the gear 704, the gear 704 can drive the connecting rod 702 to rotate, thereby driving the silicone soft clamp 703 to rotate.

[0018] Furthermore, such as Figure 3As shown, the motor 708 forms a threaded structure with the threaded rod 707 and the threaded sleeve 706.

[0019] Furthermore, such as Figure 3 As shown, the threaded sleeve 706 forms a linkage structure with the gear 704 through the rack 705, and one side of the rack 705 is connected to one side of the threaded sleeve 706, while the other side of the rack 705 meshes with the outer wall of the gear 704. Through the threaded sleeve 706, the threaded sleeve 706 can drive the rack 705 to move, and the rack 705 can drive the gear 704 to rotate.

[0020] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the airflow assembly 10 includes an air pump 1001, which is fixed to one side of the support frame 9. An air inlet pipe 1002 is provided on the top of the air pump 1001, and an air outlet pipe 1003 is also provided on the top of the air pump 1001. A support rod 1004 is fixedly connected to one side of the air outlet pipe 1003, and a jet nozzle 1005 is sleeved at one end of the air outlet pipe 1003. By activating the first sliding column 3, the first sliding column 3 can slide along the first positioning column 2, allowing the first sliding column 3 to move inside the splash guard 8, and allowing the first sliding column 3 to... The mechanical finger 4 moves and clamps the workpiece up and down repeatedly until the workpiece comes into contact with the silicone soft clamp 703, thus detaching the workpiece from the injection molded part. By activating the air pump 1001, airflow is input through the air inlet pipe 1002 and delivered through the air outlet pipe 1003. The airflow is then ejected through the jet nozzle 1005. The airflow is ejected from top to bottom inside the anti-splash cover 8 and impacts the workpiece, causing it to fall into the workpiece barrel 11, thereby preventing the workpiece from splashing.

[0021] Furthermore, such as Figure 4 As shown, the air outlet pipe 1003 and the jet nozzle 1005 form a fixed structure, and there are three jet nozzles 1005 on the air outlet pipe 1003. All jet nozzles 1005 are set at the port of the air outlet pipe 1003. Through the air outlet pipe 1003, the air outlet pipe 1003 can spray airflow through the three jet nozzles 1005.

[0022] Furthermore, such as Figure 4As shown, the air pump 1001 is provided with an air inlet pipe 1002 and an air outlet pipe 1003. The air inlet pipe 1002 can input airflow, and the air outlet pipe 1003 can output airflow. Through the air inlet pipe 1002 and the air outlet pipe 1003, the air pump 1001 can input airflow through the air inlet pipe 1002 and output airflow through the air outlet pipe 1003. The air pump 1001 and the jet nozzle 1005 form a communication structure through the air outlet pipe 1003. The air outlet pipe 1003 is located on the top of the air pump 1001, and the top of the jet nozzle 1005 is connected to the other end of the air outlet pipe 1003.

[0023] Working Principle: First, by activating the robotic arm 1, the first positioning post 2 can be moved, which in turn moves the second positioning post 5, positioning the first and second positioning posts 2 and 5 above the splash guard 8. Activating the second sliding post 6 allows it to slide along the second positioning post 5, moving within the splash guard 8 and causing the fixed plate 701 to move. Activating the motor 708 rotates the threaded rod 707, causing it to rotate within the threaded sleeve 706, moving the threaded sleeve 706. The threaded sleeve 706 then moves the rack 705, which in turn rotates the gear 704, ultimately rotating the connecting rod 702. The connecting rod 702 can rotate inside the fixed plate 701, and the connecting rod 702 can drive the silicone soft clamp 703 to rotate. By activating the first sliding column 3, the first sliding column 3 can slide along the first positioning column 2, and the first sliding column 3 can move inside the anti-splash cover 8. The first sliding column 3 can drive the mechanical finger 4 to move. By the mechanical finger 4 clamping the workpiece and moving it up and down repeatedly, the workpiece can contact the silicone soft clamp 703, thereby detaching the workpiece from the injection molded part. By activating the air pump 1001, the air pump 1001 can input airflow through the air inlet pipe 1002, and the air pump 1001 can deliver airflow through the air outlet pipe 1003. The airflow can be sprayed out through the jet nozzle 1005. The airflow is sprayed from top to bottom inside the anti-splash cover 8 to impact the workpiece, causing the workpiece to fall into the workpiece barrel 11, thereby preventing the workpiece from splashing.
