Brief introduction of installing injection manipulator in injection workshop of household appliances

Real scene of injection molding machine with injection molding manipulator

Matching the injection servo manipulator in the molding workshop of plastic parts of household appliances (air conditioning panel, refrigerator liner, washing machine shell, small household appliance shell, remote controller accessories, etc.) is a standardized automation transformation scheme of household appliances injection molding, which is mainly matched with three-axis/five-axis traverse servo models, suitable for injection molding machines of 50T-2000T tonnage, and equipped with vacuum sucker and soft rubber gripper custom fixture to grab plastic parts, so as to realize full-automatic in-mold taking, water cutting, turning over, stacking and so on.

First, the core role and advantages

Improve productivity and machine utilization.

Manipulator's action rhythm is stable, 24-hour continuous production is uninterrupted, and it is not affected by manual fatigue and shift change, so the speed of taking parts is faster, the waiting time for molding is shortened, and the overall productivity is increased by 20%-30%; The conveyor belt can be linked to realize seamless connection from injection molding to post-processing assembly line, which is suitable for mass production of household appliances.

Stabilize the appearance quality and reduce the defective rate.

The appearance requirements of household appliance shells and decorative parts are strict, and manual picking is easy to scratch, bump and squeeze. The grasping strength and position of the manipulator are unified in the whole process, and the soft sucker/cushion fixture will not scratch the plastic parts, effectively reducing the defects of top white, strain and depression, and greatly improving the product consistency; It can also be automatically embedded with copper nut inserts and labeled in the mold to reduce poor assembly.

Reduce labor costs and ease the recruitment problem.

One manipulator can control 1- more injection molding machines, replacing repetitive high-temperature picking positions, and few people can be on duty at night shift; Front-line operators can transfer jobs, adjust machines and conduct quality inspection, so as to reduce low-end manpower dependence and save labor expenses for a long time.

Improve the safe production environment in the workshop

The temperature of the injection mold for home appliances is high, and there is a risk of pinching hands when the machine opens and closes the mold, so it is easy to burn and crush by manually reaching out for the parts; The manipulator is equipped with safety door interlocking and abnormal alarm to realize unmanned operation in the mold and prevent work-related injuries; At the same time, it avoids manual misoperation and damages the expensive household appliance mold, and prolongs the service life of the mold.

Facilitate standardized management of workshop

The production beat and picking-up process are unified and controllable, and the output and bad data can be linked with the statistics of the equipment system, which is convenient for the digital and standardized management of the factory.

Second, the adaptation of common models in home appliance workshops

Three-axis servo manipulator: cost-effective, suitable for small household appliances shells, buttons, small pieces, only to complete picking and simple stacking, is the standard for workshop popularization;

Five-axis servo manipulator: it can rotate and pitch, adapt to refrigerator door liner, air conditioner shell and other large pieces, and can automatically turn over and multi-process linkage. Complex deep cavity and two-color mold are preferred;

Bull's-head heavy manipulator: matched with a large injection molding machine, it can grab 5-30kg heavy plastic parts such as washing machine inner barrel and refrigerator door panel, and the suction cups are uniformly stressed at multiple points to prevent large pieces from being deformed.

Iii. Key points of supporting installation of foundation

When installing, it is connected with the communication signal of injection molding machine, and a safety fence is added; Customize the sucker/gripper fixture according to the curved surface and size of household appliance plastic parts; Supporting nozzle shearing table and finished product conveying line to form a complete automatic forming unit; The equipment regularly maintains the guide rail and servo motor to ensure long-term stable operation.
