Inserting connecting pins – when every millimeter counts

Inserting connecting pins

Pin insertion, a standard technique in precision installation, demands sensitivity and millimeter tolerances. It has resisted automation, but thanks to six-axis force/torque sensors, that is now changing.


The average automobile today consists of up to 10,000 individual parts. To turn this immense number of individual components into a complete and functional vehicle requires nearly as huge a number of installation steps. Absolute precision is a fundamental essential: If just a single part isn’t sitting exactly where it belongs or gets out of alignment during installation, that threatens not only the cost-effectiveness of the manufacturer’s production processes, but in the worst case can even endanger the end customer.


Of course, this is not only true of the automobile industry but also for most high-tech products, all of which are now highly individualized, starting from huge numbers of small parts.


Efficient fine and precision installation is therefore a central factor in manufacturing them.


Irregularities require adaptability


A good example is the insertion of pins into close-fitting openings – an important standard process in the production industry. At the same time, tolerances are often relatively narrow: soft materials, deformation due to temperature fluctuations, and even minimally irregular workpieces require a high degree of adaptability during pin insertion.


If we want to automate the process, the lack of standardization therefore represents a challenge for industrial robots, which can provide a high degree of reproducibility, but may not necessarily have the required responsiveness and intelligence.


The insertion of pins requires sensitive millimeter-scale work. The human hand can quickly find the right approach point simply by trying it out. A conventional robot arm designed for precisely positioned fixed waypoints cannot.


OptoForce made it their goal to change this situation. This Hungarian company manufactures force/torque sensors for industrial robots. Robots by Universal Robots, KUKA, and ABB can be extended with the high-precision HEX-E and HEX-H sensors to give them a fine sense of touch. This allows them to react to their surroundings: They perceive the slightest resistance and make the corresponding course corrections in real time.


For precision installation, that’s gold. The capability of using the sense of touch expands the options for automation and allows companies to automate monotonous, repetitive work, for which human resources are hard to find.


The improved productivity and product quality at simultaneously lower costs means an added value for companies of up to 100,000 EUR per year for each robot system implemented.


The cost remains astoundingly low. Not only are the sensors powerful hardware, they also include a comprehensive software package of standard industrial applications. The “Pin Insertion” application allows inserting pins into openings to be automated in just a few steps.


Privacy Policy for processing and protecting personal data

This data protection policy applies to OnRobot.

The purpose of the policy is to ensure and document that OnRobot protects personal data in accordance with the rules for processing of personal data. The policy will also contribute to OnRobot providing information about its processing and use of registered personal data.

The policy will be reviewed each year.

Record of the processing of personal data

OnRobot processes personal data about:

  • Employees

  • Customers

  • Suppliers

  • Applicants

OnRobot has prepared a record of the processing of personal data. The record provides an overview of the processing for which OnRobot is responsible.

The personal data must be provided in order for OnRobot to enter into employment, customer and supplier contracts.

Purpose and lawfulness of the processing

Personal data are processed and archived in connection with:

  • HR management, including recruitment, hiring, dismissal and payment of salary

  • Master data for customers as well as orders and sales

  • Master data for suppliers as well as requisition forms and purchases

  • Contracts

Processing is legal by the authority specified in the appended record.

OnRobot does not use the personal data for purposes other than those listed. OnRobot does not collect more personal data than necessary to meet the purpose. 

Storage and erasure

OnRobot has introduced the following overall guidelines for storage and erasure of personal data:

  • Personal data are stored in physical folders.

  • Personal data are stored in IT systems and on server drives.

  • Personal data are not stored for longer than necessary to meet the purpose of the processing.

  • Personal data for employees are erased five years after employment has ended, and personal data about applicants are erased after six months.

Data security

Based on the appended risk assessment, OnRobot has implemented security measures to protect personal data:

  • Only employees with a work-related need to access the registered personal data have access to the data, either physically or via IT systems with rights management.

  • All computers are password protected and employees may not disclose their passwords to others.

  • Computers must have firewall and antivirus software installed, which must be updated regularly.

  • Personal data are erased securely in connection with phasing-out and repair of IT equipment.

  • USB flash drives, external hard disks, etc. containing personal data must be stored in a locked drawer or cabinet.

  • Physical folders are placed in a locked office or in locked cabinets.

  • Personal data in physical folders are erased by shredding.

  • All employees must be instructed in what to do with personal data and how to protect personal data.


Website and Cookie

  • The Personal Data Regulation allows you to treat personal data only legally for the purpose for which they have been collected. If you want to use data for purposes other than the original, you must always have the consent of the registrant.

  • Upon receipt of a business card from a customer you have his consent. If you write his information you need his signature on this paper to have a formal requirement for consent if you want to use his information. Then the customer allows OnRobot to use his data for purposes other than communication, upcoming promotions, product updates or further news including upcoming promotions, product updates and further news.

  • According to the Cookie Act, OnRobot must have the user’s consent to use this software on the user’s equipment. On The company’s intranet or similar closed group, the rules in the E-data protection directive do not apply.


Personal data about employees may be disclosed to public authorities such as the Danish Customs and Tax Administration and pension companies.


OnRobot only uses processors if they are able to provide the required guarantees that they will implement appropriate technical and organisational security measures to comply with personal data law. All processors must sign a processor agreement before processing commences.


OnRobot safeguards the rights of data subjects, including the right to access, withdrawal of consent, rectification and erasure and will inform the data subjects of OnRobot’s processing of personal data. Data subjects are also entitled to appeal to the Danish Data Protection Agency.

Personal data breach

In case of personal data breach, OnRobot will report the breach to the Danish Data Protection Agency as soon as possible and within 72 hours. The manager is responsible for this reporting taking place. The report will outline the breach, the groups of persons affected and the impact the breach may have on these persons and how OnRobot has remedied or intends to remedy the breach. If the breach entails a high risk for the persons about whom OnRobot processes personal data, OnRobot will also notify these persons. OnRobot s will document any personal data breach on an access-controlled drive.

Erasure of data

The customer should assess when personal data need to be erased by asking the question:

When is it no longer necessary to store the personal data?

OnRobot follows the practice of the Danish Data Protection Agency:

Applications Are erased after 6 months in connection with job interviews. Unsolicited applications are erased immediately.
Employee data Are erased 5 years after termination of employment.
CCTV surveillance Is erased after 30 days.
Telephone conversations Are erased immediately or after up to 3 months.
Accounting records Must be stored for 5 years from the end of the financial year.
