Choosing a suitable injection manipulator requires comprehensive consideration of many factors. The following are the methods to choose an injection manipulator according to the processed products:

I. Product size and weight

product size

If the product size is small, you can choose a small injection manipulator, which has a relatively small working range, but is flexible and can quickly and accurately complete the picking operation. For example, for the injection molding of small products such as electronic components, the small manipulator can work efficiently in a narrow space.

For larger products, such as automobile parts, large household appliance shells, etc., it is necessary to choose a manipulator with a larger working range and bearing capacity. This kind of manipulator usually has a longer arm and stronger grasping force, and can stably carry large products.

product weight

Lighter products can choose a manipulator with less load capacity to reduce costs and energy consumption. At the same time, lighter manipulators are usually faster and can improve production efficiency.

For heavier products, it is necessary to choose a manipulator with sufficient load capacity to ensure safe and reliable handling and operation. In the selection, the maximum weight of the product and the dynamic load of the manipulator in the process of grasping and handling should be considered.

Second, the product shape and structure

Product shape complexity

For products with simple shapes, such as flat plates and cylinders, a general injection manipulator can be selected, and its grasping mechanism is relatively simple, which can meet the basic requirements for taking parts.

For products with complex shapes, such as products with grooves, protrusions, holes and other structures, it is necessary to choose a manipulator with a special grasping mechanism. For example, using articulated fingers or vacuum sucker can better meet the requirements of grasping products with complex shapes.

Product structure characteristics

If the product has a fragile part or a surface that needs special protection, the softness and stability of the grasping method should be considered when selecting the manipulator. For example, for glass products or products whose surfaces are easy to scratch, you can choose to use a grasping mechanism made of soft materials or vacuum adsorption to avoid damage to the products.

For products that need to be placed or assembled in a specific direction, choose a manipulator with corresponding rotation and turnover functions, so that the products can be accurately placed in the designated position after picking up the parts.

Third, the production process requirements

productive cycle

If the production cycle is short, the manipulator is required to have high speed and high efficiency. You can choose a fast-moving manipulator and equip it with advanced control system to reduce the time of picking and placing parts and improve production efficiency.

For the case of long production cycle, a manipulator with moderate speed and good stability can be selected to ensure long-term stable operation.

Degree of automation requirements

If a highly automated production process is needed, an injection molding manipulator with intelligent functions can be selected, such as automatically identifying products, automatically adjusting the grasping position and strength, and communicating with the injection molding machine. This kind of manipulator can realize unmanned operation and improve the automation level of production.

For the situation that the degree of automation is low, we can choose a relatively simple manipulator to complete some complex tasks through manual auxiliary operation.

Special process requirements

If the product needs secondary processing, such as spraying, assembly, etc., a manipulator with corresponding function expansion interface can be selected, so as to add auxiliary equipment later and realize integrated production.

For some products that require high cleanliness, such as medical instruments and food packaging, it is necessary to choose a manipulator made of corrosion-resistant and easy-to-clean materials and equip it with corresponding cleaning devices to ensure the hygiene and safety of the production process.

IV. Cost and Budget

Manipulator price

The prices of injection molding robots with different brands, models and functions vary greatly. When choosing, we should comprehensively consider the performance and price of the manipulator according to our own budget and actual needs. Don't just pursue low prices and ignore the quality and reliability of the manipulator.

You can choose a manipulator with high cost performance by comparing quotations from different suppliers and understanding market conditions.

running cost

In addition to the purchase cost, it is also necessary to consider the operating cost of the manipulator, including energy consumption and maintenance costs. Choosing energy-saving manipulator can reduce energy consumption and operation cost.

At the same time, attention should be paid to the maintenance requirements of the manipulator, and the manipulator with easy maintenance and low maintenance cost should be selected to ensure long-term stable operation.

To sum up, choosing the right injection manipulator according to the products processed by ourselves needs to comprehensively consider the factors such as product size and weight, shape and structure, production process requirements, cost and budget. In the selection process, you can consult professional manipulator suppliers to understand the characteristics and application scope of different types of manipulators, so as to make the best choice.
