Automation

Small quantities:

Manual and semi-automatic systems:

The requirements for modern production of low to medium volume components include the following:

  • • High flexibility
  • • Short changeover times
  • • Easy handling
  • • Short "time to market"

High quantities:

Fully automated systems or production lines:

The requirements for modern production of components with high to huge quantities include the following:

  • • High availability
  • • Product-specific or product-optimized

• Low manpower requirements and service maintenance

At the beginning of a new project, it is not always clear and unambiguous which form of automation is the best possible one. Therefore, we always check different possibilities / scenarios and work out together with you the most reasonable and economical solution.

In the following we show you some examples / possibilities of welding machines with different degrees of automation.

Manual loading and unloading:

Projection Welding

 

• Manual loading of the two components (holder and pressure sensor).

• Automatic welding process (ring projection welding) including QA

• Manual unloading of the welded component

 

 

• Simple and cost-effective system

• High flexibility

• Quick changeover of electrodes or workpiece holders

 

Manual loading and automatic unloading:

 

• Manual loading of the two components (coiled bimetal and fixture)

• Automatic handling / assembly of the components

• Automatic laser welding process (two parallel welds in one pass using bifocal optics) including QA

• Automatic unloading of the welded part including reject sorting

 

 

• Simple but efficient system

• Limited flexibility

• Quick changeover of workpiece holders

Manual and automatic loading as well as manual unloading:

Laser Spot Welding

 

• Manual loading of the brush block

• Automatic loading of contact brushes from reel

• Automatic handling / assembly of the components

• Automatic laser welding process (11 respectively 15 welding points) including QA

• Manual unloading of the welded component

 

• Simple but efficient system

• Limited flexibility

• Quick changeover of workpiece holders and product-specific tools

Fully automatic machines:

Bi-Metal Winding

 

• Automatic loading of bimetals (bulk material) into circulating workpiece carriers.

• Automatic cutting and assembling of glass fiber hose

• Automatic winding, stamping and welding of resistance wires

• Automatic unloading of the finished part including reject sorting

 

• More complex and efficient system

• Limited flexibility, high availability

• Fast exchanging of workpiece carriers and product-specific tools

Bowl Feeder

 

• Automatic loading of rotationally symmetrical contact carriers (bulk material) from two bowl feeders into turntable disc

• Automatic feeding, cutting and welding of AgNi wire from reel including QA

• Automatic forming of the welded contact wire

• Automatic unloading of the finished component including reject sorting

Fully automatic production line:

CONTACTOMAT CA

 

Fully automatic contact manufacturing line with the following equipment:

• Strip de-coiler with straightening station

• Pre-punching press with punching-bending tool

• Contact brazing machine 1 with brazing material supply from reel, powder metallurgical contacts as bulk material, contact forming and QA

• Contact brazing machine 2 with brazing material supply from reel, powder-metallurgical contacts as bulk material, contact forming and QA

• Final punching press with punching-bending tool including QA and automatic reject sorting

CONTACTOMAT CH3

Fully automatic contact manufacturing line with the following equipment:

• Strip de-coiler with straightening station

• Pre-punching press with punching-bending tool

• Contact welding machine 1 with automatic feeding, cutting and welding of contact wires / tapes from reel, contact forming and QA

• Contact welding machine 2 with automatic feeding, cutting and welding of contact wires / tapes from reel, contact forming and QA

• Thread forming machine with four tapping stations including strip cleaning

• Final punching press with punching-bending tool including QA and automatic reject sorting
