What matters should be paid attention to when selecting injection manipulator in plastic pallet processing plant?

Key Points for Attention in Selection of Injection Manipulator for Plastic Pallet Processing Factory (Adapting to Large Pallet, Thick Wall, Heavy Load and Deep Cavity Mold)

1. Model selection: give priority to the bull's head manipulator, and put an end to the common cross-walking/oblique arm.

The plastic pallet has large size, high dead weight and long mold opening stroke, and the injection molding machine of 650T and above must choose tauren three-axis/five-axis manipulator;

It is forbidden to use a small transverse manipulator: the stroke is insufficient, the rigidity is poor, the large pieces are easy to shake and the products are bumped and deformed;

Choose multiple double-section extended stroke styles to match the vertical take-out stroke of the deep cavity die of the tray, so as to avoid the interference of the die.

Second, the load and rigidity (core key)

Check the full load weight: tray finished product+nozzle+total weight of fixture, and more than 30% allowance shall be reserved for the rated load of manipulator;

Fuselage structure: thick cross beam, heavy guide rail and reinforced frame, which will not deform or shake during long-term heavy-load operation;

Drive configuration: servo full drive is selected for the production of large parts, which ensures accurate positioning, eliminates low-frequency models, and prevents parts from being offset and dropped.

Third, customization and adaptation of the picking fixture

Don't use universal sucker: the tray has many hollows and special structure, so it needs to customize the combined fixture (vacuum sucker+mechanical gripper mixing);

Partition sucker layout: for Tian Zi, Chuanzi and nine-legged pallet structures, multi-point adsorption is used to prevent unilateral stress cracking and deformation;

Equipped with buffering device: the thick-walled tray has large demoulding resistance, buffering and damping, and reducing the hard drawing scar of the product.

Four, the mold and field adaptability

Confirmation of mold opening stroke: check the capacity modulus, mold thickness and safety door spacing of injection molding machine in advance to ensure that the manipulator enters and exits without interference;

Loading and unloading space: the pallet occupies a large area, so it is necessary to reserve space for falling and stacking, and the transverse travel can be extended optionally;

Adapt to rapid demoulding: the cooling cycle of the tray is fixed, the speed of the manipulator is adjustable, which matches the production rhythm and does not slow down the production capacity.

Five, durability and production conditions.

Workshop environment: the pallet factory has a lot of dust and 24-hour continuous mass production, which requires dust-proof sealing of the whole machine and wear resistance of the line;

Durability of accessories: brand motors, cylinders and vacuum generators are selected, and the consumable accessories are generally easy to purchase and maintain;

High-temperature-resistant configuration: the parts near the mold area are high-temperature-resistant, adapt to the high-temperature environment of injection molding, and prolong the service life.

VI. Function and Automation Expansion

Basic functions: anti-falling, anti-collision early warning, origin reset and fault alarm in the mold to reduce the risk of mold collision;

Expand demand: in the later stage, the integrated functions of automatic stacking, stacking and cutting nozzle can be installed to reduce labor;

Simple operation: support one-click calling formula, one-click switching parameters for trays with different specifications, and adapt to multi-category production.

Seven, after-sales and cost control

Priority is given to special manufacturers in heavy industry, and there are mature cases in pallet industry to avoid insufficient adaptation of general equipment manufacturers;

Clear after-sales: it is difficult to maintain large manipulator, which requires local after-sales, quick door-to-door and regular maintenance service;

Cost-effective ratio: Reject low allocation and reduce allocation; heavy-duty models get what they want for a penny, resulting in lower long-term operation failure rate and maintenance cost.
