Adapting to large-scale injection production | Tianqixing Niutou injection manipulator, unlocking a new automation scheme for large-scale plastic parts

In the upgrading process of injection molding manufacturing industry, the production of large plastic parts has always been the key and difficult point of automation transformation. Large automobile parts, household appliance shells and logistics storage plastic parts generally have the characteristics of large size, high weight, deep cavity and abnormal shape. The traditional frame-type traversing manipulator is prone to problems such as spatial interference, insufficient rigidity, shaking and bumping of picking, and manual operation has pain points such as high labor intensity, high safety risk and unstable production rhythm, which restricts the release of factory capacity and quality improvement. Jiangsu Tianqixing Robot Co., Ltd. has been deeply involved in the research and development of injection automation equipment for medium and large-scale injection molding scenes, and launched a series of tauren injection manipulators. Relying on the open structure design, full servo drive system and customized adaptability, it provides stable and reliable automatic picking and in-mold operation solutions for 650 t 3200 t tonnage injection molding machines, helping injection molding enterprises to reduce costs, improve quality and increase efficiency.

The bull's head injection manipulator is different from the conventional frame manipulator, and its core feature is the open structure on three sides, the arm is integrally connected with the drawing beam, and the front and both sides of the mold are not blocked by the column structure, which completely avoids the structural interference in the process of taking and placing large workpieces, which is also the irreplaceable core advantage of this model in the field of large-scale injection molding. Tianqixing tauren manipulator adopts a high-rigidity frame body, the crossbeam and guide rail base are thickened and strengthened, and it is equipped with a double-speed arm structure, which not only has a long effective stroke, but also ensures the structural stability of the whole machine under heavy load. The rated load of the equipment covers 10‑120kg, which can calmly cope with the operation requirements of heavy load and deep cavity mold, and it is not easy to shake and deform after long-term continuous operation, effectively avoiding the bad phenomena such as scratches, bumps and deformation of large products. The transmission component is a combination of high-precision linear slide rail and servo motor, and the repeated positioning accuracy of the whole machine is excellent. The movement process adopts S-type acceleration and deceleration algorithm, and the start-stop action is soft and smooth, with little impact. Whether it is quick picking up parts, in-mold inserts or in-mold labeling operations, it can ensure the position accuracy and reduce the production loss caused by positioning deviation.

As for the control system, Tianqixing Niutou Injection Molding Manipulator is equipped with a mature and stable drive and control integrated control system, which has strong anti-interference ability and rapid signal interaction response. It can complete signal linkage with large-scale injection molding machines of mainstream brands in the market, and cooperate with the whole set of action logic of mold opening and closing, taking parts and returning, thus shortening the production cycle time of a single piece and effectively improving the productivity of injection molding machine equipment tqx-robot. The system has built-in fault self-diagnosis function, and once there is an abnormality, the touch screen intuitively displays the fault code and prompt information, which is convenient for on-site personnel to quickly check and handle; At the same time, it is equipped with multiple protection mechanisms, such as hardware limit switch, buffer anti-collision mechanism, safety door interlock, etc., with dual protection of software and hardware, so as to reduce the risk of mold collision and misoperation and protect the production safety in the workshop. The operation interface is simple and friendly, the process parameters can be edited and stored directly in the man-machine interface, and the process formulas of different products can be called with one button, which reduces the learning threshold of operators and facilitates the factory to switch production orders quickly.

Rich industry landing scenes fully verify the practical value of Tianqi Star Niutou Injection Manipulator. In the auto parts industry, bumper, middle net, instrument panel frame, door trim panel, battery shield, large air duct and other products can reach 12m in length, with heavy weight and complex cavity. With the open working space and AC servo rotating shaft, Tianqixing Niutou manipulator can flexibly adjust the posture of the workpiece, smoothly complete the removal of long shaped parts, and widely serve the plastic parts molding production line of new energy vehicles. In the field of home appliance manufacturing, large-area thin-walled plastic parts, such as air conditioning panel shell, refrigerator door side plate, washing machine shell, TV back plate and water heater shell, are prone to deformation. The manipulator can be matched with a custom-made sucker and claw combination fixture to evenly absorb at multiple points, smoothly complete the pick-up and transfer, protect the appearance integrity of plastic parts and reduce the appearance defect rate. Production scene of plastic parts in logistics storage, super-large products such as plastic trays, large sorting trash cans, turnover baskets, tubs, etc., the characteristics of large mold opening stroke and high demoulding resistance, high load and large stroke of tauren manipulator fully adapt to the working conditions, and the IML process of in-mold labeling can be expanded to meet the demand of integrated production of packaged plastic parts. In addition, products such as large-scale bathroom components, outdoor tables and chairs plastic parts, and electric vehicle shell accessories can also be automated by relying on Tianqi Star Niutou manipulator.

In addition to the standard models, Jiangsu Tianqixing robot supports the personalized customization development of tauren manipulator. According to the tonnage of injection molding machine, mold size, product weight form, workshop height and subsequent expansion process, the arm stroke, load specification and end fixture structure can be adjusted pertinently, which can connect the conveyor belt, water cutting equipment and inspection station, create a simple automatic unit from picking to post-processing, fit the real production line layout of the factory, and avoid the problem that general equipment is not acclimatized.

Relying on the perfect full-cycle service system, Tianqixing provides customers with a full set of services from early working condition survey and scheme selection, to equipment production and delivery, on-site installation and commissioning, personnel operation training, and then to later maintenance inspection and rapid fault response. Before leaving the factory, all the equipment is fully simulated for heavy-duty trial operation, and quality control is carried out at all levels to reduce the on-site failure rate; The after-sales team quickly responds to customers' demands, minimizes the downtime of the production line, and ensures the stable operation of customers' production.

As the automation transformation of manufacturing industry continues to advance, the automation demand of large-scale injection molding production will continue to grow. Jiangsu Tianqixing Robot will continue to polish the product performance of Niutou injection manipulator, iteratively optimize the structure and control system, precipitate more industrial process plans, help more injection factories solve the automation problem of large plastic parts, and empower the plastic manufacturing industry with high-quality development with intelligent equipment.
