LHZ High Precision Automatic Welding Manipulator with Seam Tracing Unit

Quantity:

The welding manipulator with seam tracing unit is the “high-tech” product of its type. With the optional seam tracing unit equipped, the product becomes high precision automatic welding manipulator, which can fulfil various welding mode (SAW/ CO2/TIG/MIG) with required accuracy, without much human intervention (Only setting parameters & validation at the beginning).

 

Technical Brief on LHC Welding Column and boom with Seam Tracing Unit:

   1. Purpose of seam tracing unit:

     - It tracks position of welding torch, and manipulates this position to optimum condition all along in the

       process of welding, for the target of LHZ automatic high precision welding manipulator delivering best

       welding quality of finished product;

    2. Origin of seam tracing unit:

     - It is an outsourced component of LHZ high precision automatic welding column and boom;

    3. Constitutes of seam tracing unit:

     - The welding seam tracker consists of sensor, control box and actuator (motorized slider), etc.

    4.Working Principle of seam tracing unit:

    1) Data on welding face variation is collected by sensor which touches work-piece during welding, and

       calculated by control system;

    2) Distance between welding torch and work-piece would be adjusted accordingly when it is necessary by

       actuator, assuring welding quality of the LHZ automatic high precision welding column and boom;

     5. Structure and Components of seam tracing unit:

     1) This sensor adopts imported components and advanced assembly technology from the Ministry of Aviation

         and Aerospace, with high quality, long service life;

     2) The two-dimensional probe sensor (see below picture). This probe sensor is applicable to overlap welding,

       fillet welding and butt welding. Different probes, like mushroom-type, Y-type and roller-type etc., are available

       for different work-pieces of the LHZ automatic high precision column and boom;

 Fig1--Sensor

     3) Controller (see below picture): Using the latest CPU as its core part and assembled with anti-jamming control

       procedure, this controller is highly efficient and reliable. It has user-friendly interface, light touching keys with

       100k time’s life circle and graphics LCD, all of which make it much easier to operate, set procedure and

       control. It is installed at of the boom front end of LHZ high precision automatic column and boom;

     4) Actuator (see below picture): This actuator is motorized high precision sliders, with once-through shape 

      aluminum cover and reasonable compact structure. Inside, it uses straight-line rail which runs fast and easily. It

      uses DC low voltage (DC 24V) motor as its drive element, which conforms to European, American and many 

      other countries safety standards. In the process of welding, this actuator serves as executing unit for adjusting

      welding torch position of the LHZ precise automatic welding manipulator;

    6. Model selection of seam tracing unit:

    1) There are 3 standard models of the seam tracing unit to choose from:

    2) ED-ST05 is for MIG/ TIG/ CO2 welding;

    3) ED-ST10 is for SAW;

    4) ED-ST20 is for Tandem SAW;

    5) Detailed parameters we will provide manual of the seam tracing unit as part of the technical documents of

        the LHZ precise automatic welding column and boom;

     7. Use of seam tracing unit:

     1) As mentioned above, there is operating manual of seam tracing unit, which we will hand over to customer 

        when making delivery of the LHZ welding manipulator with seam tracing unit;

     2) We give customer training and technical service on the product as part of our service terms;

     8. Complement on adoption of the seam tracing unit:

     1) The seam tracing unit is a very powerful tool for guaranteeing welding quality of the LHZ automatic high 

         precision welding manipulator;

     2) On the other hand, the performance of the whole set of equipment depends on coordination of all the units

        of the LHZ high precision automatic welding manipulator.
