The vary of manipulation duties that robots can perform is rising, in accordance with FAULHABER. It consists of all the pieces from greedy and holding to clamping and screwing, in addition to foaming and welding, stated the German firm.

In terms of standardized mass manufacturing, specialised robots can carry out the identical duties day and evening. However many processes require flexibility, akin to in relation to batch measurement 1. That is additionally necessary to save lots of on funding prices. The larger the vary of duties {that a} robotic can perform, the higher, FAULHABER stated in a weblog put up.

Clever Peripherals for Robots (IPR) goals to resolve these drawback with its TKX device changer. Mounted to the top of a robotic arm, it may well take away quite a lot of instruments from a rack, in accordance with IPR.

For instance, TKX allows the robotic to first grip and place a workpiece, then course of it with instruments, and eventually test and doc the standard with a contour sensor or a digital camera. For this, the adapter wants appropriate feed-throughs for the corresponding device capabilities.

The TKX sequence gives choices, in addition to a number of lateral screw-on surfaces for added modules. Nevertheless, the principle activity of the device changer is to securely lock the device when it’s picked up and to rapidly and constantly launch the lock once more when it’s set down after use.

Purposes decide selected of pneumatic or electrical

Historically, many industrial purposes use pneumatic energy transmissions, stated FAULHABER. Compressed-air know-how has confirmed itself over many years, and it’s appropriate for dealing with very heavy objects, the firm famous. However a pneumatic system requires compressors, strains, and its personal management system with quite a few mechanical parts – a substantial funding in new methods.

In industries with elevated calls for on cleanliness and hygiene, akin to microelectronics or meals, pneumatics are out of the query due to the unavoidable emission of compressed air. And pneumatics are an absolute no-go in clear rooms. Eppingen, Germany-based IPR stated it has seen a big development in the direction of using electrical drives as a substitute of pneumatic ones.

“Along with the hygienic security, electrical motors are way more versatile in use,” stated the corporate. “Not like compressed air connections, energy sockets can be found virtually wherever.”

“In newly constructed industrial vegetation, pneumatic methods are typically now not put in,” IPR added. “For cobots and smaller robots in addition to for decentralized areas, the electrical model is sort of all the time the higher resolution.”

The truth that the electrical drive is an actual different to pneumatics at the moment additionally has one thing to do with motor know-how, defined Roman Batz, growth engineer at IPR.

“Nice strides have been made lately,” he stated. “For our purposes, we mainly want numerous energy with very small dimensions. FAULHABER gives motors that may simply maintain their very own in comparison with pneumatic drives.”

FAULHABER motors to open, shut, and maintain

Holding up can also be meant fairly actually right here. At present, essentially the most highly effective electrical mannequin within the TKX sequence, the TKE 300, is appropriate for dealing with objects weighing as much as 300 kg (661.3 lb.), stated IPR.

In metallic processing, robots can deal with heavy masses akin to forged blocks or massive cast elements. The pulling drive of their total mass then acts upon the locking ring within the TKX changer.

The torque equipped by the motor in standby mode can be sufficient for secure holding. However to make sure notably dependable fixation, IPR has additionally put in self-retaining kinematics, which had been developed in-house.

“A brushless motor from the FAULHABER BXT household gives the driving drive for opening, closing, and holding,” FAULHABER stated. “With its exterior rotor know-how, it achieves a ratio of torque to weight and quantity that’s unmatched in the marketplace. This energy density is without doubt one of the conditions for the distinctive promoting level of the brand new product household from IPR.”

“The TKX sequence are the primary device changers in the marketplace which can be out there on the identical platform with each pneumatic and electrical drives – we even have a handbook model within the product vary,” Batz stated. “Which means the complete vary of equipment can be utilized with all drive sorts with out retooling. And switching to electrical operation can also be fairly simple. This opens up new potentialities for robotic automation.”

Parts designed to be dependable, simple to mix

The TKE changers can be out there in seven sizes for dealing with workpieces from 3 to 300 kg (6.6 to 661.3 lb.), in accordance with IPR. The electrical variant of the product household thus covers a variety of purposes, from light-weight robots to stationary purposes. The scale of the BXT motors used are tailored to the applying.

“The vary of sizes and the massive choice of appropriate gears for the optimum discount in every case was an necessary criterion for us,” Batz stated. “Robots ought to have the ability to obtain seven-digit cycle numbers with out upkeep. So solely a brushless motor with the best doable processing high quality can be utilized. It needs to be simple to regulate and handle with out further management – the built-in pace controller takes care of that. Final however not least, the parts have to have the ability to face up to temperatures of as much as +80°C.”

IPR procures all of its micromotors from FAULHABER. “We began working collectively a few years in the past, lengthy earlier than my time,” Batz stated. Along with the distinctive high quality of the merchandise, different features play an necessary position for him.

“It begins with the quite simple design of motor-gear combos on the FAULHABER web site,” stated Batz. “It takes just some clicks to get a complete overview. The technical particulars are very nicely documented, and in relation to exactly calculating the finer factors – effectivity, energy consumption, temperature growth over time, and many others. — I all the time get the assist I would like.”
