Assisted robotic arm is currently a popular tool in the industrial market, which can save manpower and material resources, and quickly complete manual operations, making work more efficient. The positive suction cup is an essential equipment during this operation. The commonly used vacuum suction cups include flat suction cups, corrugated suction cups, elliptical suction cups, and special suction cups. Different vacuum suction cups can be selected according to the different shapes and actual needs of the items. So what are the characteristics of these vacuum suction cups?

1、The performance of flat suction cups: high positioning accuracy, compact design, and small internal volume can minimize gripping time, achieve high lateral force, and have good sealing characteristics on flat workpiece surfaces with wide sealing lips. When grabbing workpieces, it has good stability, and the embedded structure of large-diameter suction cups can achieve high suction force (such as disc-shaped suction cups), bottom support, large and effective suction cup diameter, and a variety of suction cup materials. Typical application areas of variable frequency suction cups: handling flat or slightly disc-shaped workpieces with flat or slightly rough surfaces, such as metal plates, cardboard boxes, glass plates, plastic parts, and wooden boards.

2、Characteristics of corrugated suction cups: 1.5 fold, 2.5 fold, and 3.5 fold corrugated. Has good adaptability to uneven surfaces, has a lifting effect when grasping workpieces, compensates for different heights, gently grasps vulnerable workpieces, and has soft bottom ripples. The handle and upper ripple of the suction cup have high hardness, soft and adaptable conical sealing lips, bottom support, and a variety of suction cup materials. The typical application areas of corrugated suction cups are handling uneven disc-shaped workpieces, such as automotive metal plates, cardboard boxes, plastic parts, aluminum foil/thermoplastic packaging products, and electronic components.

3、The performance of elliptical suction cups: optimal utilization of suction surfaces, suitable for long convex workpieces. The vacuum suction cup with enhanced hardness has a small size and high suction force, and is as versatile as flat and corrugated suction cups. It is made of a variety of suction cup materials and has a high gripping force with an embedded structure (disc-shaped suction cup). Typical application areas of elliptical suction cups: handling narrow and small workpieces with gripping surfaces, such as pipe fittings, geometric workpieces, wooden strips, window frames, cardboard boxes, tin foil/thermoplastic packaging products.

4、Special suction cup: Like ordinary suction cups, it has universality, and the special material and shape of the suction cup make it suitable for specific application areas/enterprises; The typical application area of special suction cups is for handling workpieces with special properties, such as fragile, porous, and easily deformable surface structures.
