Manual Soldering Machine

The manual soldering machine is an economic solution to solder the

connectors on heatable backlites. It is well adapted for flexible

production as well as for using as a back-up unit for automated

soldering systems. It gives excellent results and reliable soldering quality.

 

Construction

The equipment is a light-weight mobile unit with compact

construction mounted on wheels. The soldering head, with two tungsten

electrodes, is controlled pneumatically. The automatic feed of ­soldering

wire is adjustable. The workstation is a rotary table, where the glass is positioned.

 

Specifications

Total weight: 120 kg

Electric supply: 220 V, 50/60 Hz

Compressed air: 6 bar

 

The equipment is mounted on wheels, and consists of

 

  • Power source
  • Soldering head
  • as single head or with separate docking clamp
  • 2 tungsten electrodes
  • soldering wire on two coils
  • adjustable feed of the wire
  • operation controlled pneumatically
  • electric supply for soldering, cable 25 mm2
  • Switch pedal
  • Balancer
  • Workstation, adjustable aluminium frame support

 

Operating Cycle

  • Manual loading of glass on workstation
  • Manual positioning of the soldering head on the glass or docking clamp
  • Manual feed of the connector
  • Automatic soldering cycle
  • electrodes lowered
  • power on
  • soldering
  • cooling period
  • removal of electrodes
  • Removal of the soldering head
  • Manual unloading of glass

 

The soldering cycle is short : just a few seconds.

The soldering can be done immediately after tempering on a still warm glass, or later, after removing possibly oxidized surface.

All types of connectors are suitable, of copper or coated. Standard connector holder of the machine suits most connector types. Special holders are available according to customer needs.

2-head Manual Soldering Machine

2-head manual soldering machine is an economic solution for

soldering connectors of any shape to any location on the backlite.

Any pre-soldered or laminated connectors can be used.

It is well adapted for flexible production as well as for using as

a back-up unit for automated soldering systems. It gives excellent

results and reliable soldering quality.

 

Construction

The equipment is a light-weight mobile unit with compact construction. The workstation is a table, where the glass is positioned and fixed. The soldering heads, mounted on articulated arms, with two tungsten electrodes, are individually, manually controlled, which enables soldering in any position in any angle on the glass.

Semi-automatic soldering machine with positioning jig

This machine is very suitable for mixed production, equipped with a positioning jig, suitable for each

or a few different backlites models. The soldering heads are positioned in the guide indents of the

jig, thus descending at the exact, desired location, corresponding to each backlite model.

 

Composition

The positioning of the glass is assured

with 3 fixed and 1 mobile pinion, which hold the glass in place on the positioning jig during the soldering

cycle. The system comprises :

• A bridge, 2500 mm wide and 2000 mm high made of sturdy aluminium profile

• A workstation to hold the jig, located between the vertical columns of the bridge.

• An electric control cabinet, 600 x 600 x 350 mm, containing the control equipment common to

both soldering heads, and a power transformer for soldering head No. 1. On the door of the control

cabinet are mounted: power indicator, main breaker, 2 voltage indicators for adjustment of

power supply to the electrodes, and 2 knobs for adjustment of the auto-transformers for primary

power supply.

• Another electric cabinet, containing a power transformer for soldering head No. 2.

• Control panel, the location of which is chosen by the customer.

• 2 soldering heads, suspended on the bridge and manipulated with coil elevators

 

Option

Pre-heating system for the glass : hot air blower with 2 fully adjustable nozzles.

This system is located below the workstation, with 360° rotation, independent of the rotation of the

worksta- tion. The blower is movable along the arm and its position can be adjusted on 2 axes to

enable exact direc- tion of the hot air flow onto the points to be soldered.

 

Operation

The selected positioning jig is placed onto the workstation, the soldering heads are docked into their

corres- ponding guide indents on the jig.

 

The glass is placed between the fixed positioning pins and the connector guide is placed on the glass.

If included, the optional hot air nozzles are adjusted according to the glass model.

The hot air blower is started with the pushbutton and when the glass surface reaches the correct

tempera- ture the hot air blower stops.

The connectors are placed into their corresponding slots

Power is connected to the electrodes and soldering starts, with simultaneous measurement of

soldering intensity ( A ). A warning signal indicates exceeded set parameters.

 

The electrodes are retracted after a short cooling time and the soldering heads are raised.

The glass is unloaded from the workstation and visual control is made

The automatic cycle takes approx. 28” ( incl. pre-heating phase and cooling ).
