Description

Technical Field

[0001] This utility model relates to a liquid silicone horizontal multi-cavity injection molding part removal robot, and more particularly to a liquid silicone horizontal multi-cavity injection molding part removal robot with an integrated unloading device. Background Technology

[0002] Liquid silicone injection molding (LSR) is a highly efficient and precise manufacturing process specifically designed for producing high-performance elastomer parts made from liquid silicone rubber. It differs significantly from traditional thermoplastic injection molding because the LSR material is liquid before processing and is cured into an elastomer within a mold through heating (vulcanization).

[0003] The process flow is as follows: feeding → metering and mixing → injection → vulcanization (curing) → demolding.

[0004] In the liquid silicone rubber (LSR) injection molding process, the removal of the preform (usually the runner head and the part together) after demolding is a key step to ensure product integrity and production efficiency. Because the vulcanized LSR material has high elasticity, softness and slightly tacky surface (especially immediately after demolding), the removal method needs to be designed according to the product shape, size, degree of automation and cleanliness requirements.

[0005] Robotic arm part handling (the mainstream automation solution) has advantages such as high stability, integration with subsequent processes (deburring, inspection), and compliance with cleanroom requirements, and is therefore widely used in the manufacturing industry of 3C products. The part handling process involves the robotic arm being equipped with a customized end effector (suction cup, robotic gripper, etc.). After the mold is ejected, the robotic arm precisely grasps the blank and moves it to the conveyor belt or post-processing station.

[0006] However, during the process of existing robotic arms accurately grasping billets and moving them to the conveyor belt or post-processing station, the billets often stick to the end effector of the robotic arm due to their slightly sticky surface, leading to unloading failures and affecting the automated production process.

[0007] Therefore, the applicant has proposed this utility model. Summary of the Invention

[0008] The purpose of this invention is to provide a liquid silicone horizontal multi-cavity injection molding part-removing robot with an integrated feeding device to overcome the shortcomings of the prior art. The push plate in its structure can apply feeding assistance to the blank that is stuck to the gripper of the robot.

[0009] To achieve the above objectives, this utility model discloses a liquid silicone horizontal multi-cavity injection molding part-removing robot with an integrated feeding device, comprising: Parallel finger cylinder and robotic gripper, wherein the parallel fingers of the parallel finger cylinder are connected to the robotic gripper for transmission, and the material head of the blank is clamped by driving the two robotic grippers to move in parallel. The system includes a dual-axis cylinder and a push plate, with the push plate having a notch. The piston rod of the dual-axis cylinder is connected to the push plate for transmission. During the reciprocating linear motion of the push plate, the two robotic grippers always pass through the notch of the push plate, while the parts and flow channels that hold the blanks on the two robotic grippers are on the displacement path of the non-notch portion of the push plate.

[0010] In the process of the liquid silicone horizontal multi-cavity injection molding part-removing robot of the above-mentioned integrated feeding device accurately grasping the blank and moving it to the conveyor belt or post-processing station, during the blank feeding stage, the dual-axis cylinder can apply feeding assistance to the blank that is stuck to the robot's gripper by driving the push plate, thereby realizing the separation of the blank from the robot's gripper and avoiding the situation of "the blank sticking to the robot's gripper due to the slight stickiness of the surface, resulting in feeding failure" to the greatest extent.

[0011] Furthermore, the aforementioned integrated unloading device for liquid silicone horizontal multi-cavity injection molding part removal robotic arm preferably includes, in its structure: The system includes a dual-axis cylinder and a cleaning brush. The piston rod of the dual-axis cylinder is connected to the cleaning brush for transmission, and the cleaning brush is driven to move linearly to clean the liquid silicone injection molding die.

[0012] Furthermore, its structure also preferably includes: The system includes an air pipe connector, a gas flow channel plate, and an air nozzle. The air pipe connector is sealed and connected to the air inlet of the gas flow channel plate, while the air nozzle is sealed and connected to the air outlet of the gas flow channel plate. The piston rod of the dual-axis cylinder is also connected to the gas flow channel plate for transmission, and the air nozzle is driven to move linearly to achieve air knife cleaning of the liquid silicone injection molding mold.

[0013] After high-temperature molding, liquid silicone may leave trace amounts of uncured material or release agent. The air knife formed by the cleaning brush and air nozzle can promptly remove the residue on the liquid silicone injection mold (especially the cavity), avoiding contamination of subsequent molded parts, thereby protecting the mold, extending the equipment life, and ensuring the quality of the molded parts.

[0014] In addition, integrating the cleaning brush and air nozzle directly into the part-picking robot arm enables automated cleaning, reducing the frequency of manual cleaning downtime and improving production efficiency.

[0015] Furthermore, the aforementioned integrated feeding device for liquid silicone horizontal multi-cavity injection molding part-retrieving robot preferably includes, in its structure, a bracket, on which parallel finger cylinders, dual-axis cylinder one, and dual-axis cylinder two are all mounted, facilitating the part-retrieving robot to be mounted as a whole onto the robotic arm of an automated robot.

[0016] Compared with the prior art, the liquid silicone horizontal multi-cavity injection molding part-removing robot with integrated feeding device obtained by this utility model has the following technical effects: This utility model relates to an integrated feeding device for liquid silicone horizontal multi-cavity injection molding parts removal robots that precisely grasp blanks and move them to a conveyor belt or post-processing station. During the blank feeding stage, a dual-axis cylinder drives a push plate to apply feeding assistance to the blanks that are stuck to the robot's grippers, thereby achieving the separation of the blanks from the robot's grippers. This minimizes the possibility of feeding failures caused by the blanks sticking to the robot's grippers due to their slightly sticky surface, thus improving the efficiency of automated production.

[0017] After high-temperature molding, liquid silicone may have trace amounts of uncured adhesive or release agent remaining. This utility model is a liquid silicone horizontal multi-cavity injection molding part removal robot with an integrated unloading device. The cleaning brush and air knife formed at the air nozzle can promptly remove residues on the liquid silicone injection molding mold (especially the cavity), avoiding contamination of subsequent molded parts, thereby protecting the mold, extending the equipment life, and ensuring the molding quality of the parts.

[0018] Finally, the liquid silicone horizontal multi-cavity injection molding part-retrieving robot with integrated feeding device of this utility model has strong overall structure and is easy to install on the robotic arm of an automated robot. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, in one embodiment of this utility model, the liquid silicone horizontal multi-cavity injection molding part-retrieving robot with integrated feeding device provided in this embodiment includes: Four sets of parallel finger cylinders 1 and robotic grippers 2. The parallel fingers 1-1 of each set of parallel finger cylinders 1 are connected to the robotic grippers 2 through transmission, and the material head 100-1 of the blank 100 is clamped by driving the two robotic grippers 2 to move in parallel. A set of dual-axis cylinder 3 and push plate 4, the push plate 4 having four notches 4-1; the piston rod of the dual-axis cylinder 3 is connected to the push plate 4 for transmission, and during the reciprocating linear motion of the push plate 4, the two robotic grippers 2 of different sets always pass through the corresponding notches 4-1 of the push plate 4, while the parts and flow channels 100-2 of the blank 100 held on the two robotic grippers 2 are on the displacement path of the non-notch section 4-2 of the push plate 4.

[0023] And, bracket 5; All parallel finger cylinders 1 are arranged in a row and installed on the bottom surface of the bracket 5, with sufficient clearance between each pair to avoid positional conflicts between the parts of the blank 100 held by the grippers 2 of different groups of robotic arms and the flow channel 100-2; the dual-axis cylinder 3 is installed on one side of the bracket 5, so that the part-retrieving robotic arm can be installed as a whole on the robotic arm 200 of the automated robot, such as... Figure 5 As shown.

[0024] During the process of the liquid silicone horizontal multi-cavity injection molding part-removing robot of the aforementioned integrated unloading device precisely grasping the blank 100 and moving it to the conveyor belt or post-processing station, in the unloading stage of the blank 100, the dual-axis cylinder 3 can apply unloading assistance to the blank 100 that is adhered to the robot's gripper 2 by driving the push plate 4, such as... Figure 2 and Figure 3 As shown, when the pusher plate 4 moves downward, the non-notch portion 4-2 of the pusher plate 4 will abut against the parts and flow channel portion 100-2 of the blank 100 that are stuck to the robotic gripper 2. At this time, the robotic gripper 2 is in the open state and does not hold the material head 100-1 of the blank 100. Furthermore, under the driving force of the downward force of the pusher plate 4, the blank 100 is further pushed to peel off from the robotic gripper 2, thereby avoiding the situation of "the blank 100 sticking to the robotic gripper 2 due to the slight stickiness of the surface, causing the material feeding failure" to the greatest extent.

[0025] As a second embodiment of this utility model, the liquid silicone horizontal multi-cavity injection molding part-retrieving robot with integrated feeding device provided in this embodiment has a generally consistent structure with the aforementioned first embodiment, such as... Figure 6 As shown, however, the liquid silicone horizontal multi-cavity injection molding part-retrieving robot with integrated feeding device described in this embodiment also includes the following in its structure: A set of dual-axis cylinder 6 and cleaning brush 7, wherein the piston rod of the dual-axis cylinder 6 is connected to the cleaning brush 7 for transmission, and the cleaning brush 7 is driven to move linearly to clean the liquid silicone injection molding mold.

[0026] A set of air pipe connectors 8, gas flow channel plates 9, and air nozzles 10 are provided; wherein, the air pipe connectors 8 are sealed and connected to the air inlet of the gas flow channel plates 9; and the air nozzles 10 are sealed and connected to the air outlet of the gas flow channel plates 9; the piston rod of the dual-axis cylinder 6 is also connected to the gas flow channel plates 9 for transmission, and the air nozzles 10 are driven to move linearly to achieve air knife cleaning of liquid silicone injection molding molds.

[0027] The second dual-shaft cylinder 6 is installed on the other side of the bracket 5.

[0028] After high-temperature molding, liquid silicone may have trace amounts of uncured adhesive or release agent remaining. In this embodiment, the air knife formed by the cleaning brush 7 and the air nozzle 10 can promptly remove the residue on the liquid silicone injection molding mold (especially the cavity), avoid contaminating subsequent molded parts, thereby protecting the mold, extending the equipment life, and ensuring the molding quality of the parts.

[0029] In addition, integrating the cleaning brush 7 and air nozzle 10 directly into the picking robot arm enables automated cleaning, reduces the frequency of manual cleaning during downtime, and improves production efficiency.

[0030] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
