Description
Technical field
The utility model relates to laser welding apparatus, belong to field of laser processing.Applied to automobile industry copper electrode, instrument
The laser welding of the components such as instrument, connector, busbar connector promotes welding quality and weldquality.The utility model provides one
Focal length of the kind for laser welding is servo-actuated testing agency, is mainly sensed by detection pressure head, tracking measurement plate, servo-actuated slide unit, ranging
The composition such as device detects in due course and carries out laser welding after compensation welding focal length automatically.
Background technique
Electronic apparatus, copper electrode, instrument and meter, connector, busbar connector are play an important role in the automotive industry, especially
New-energy automobile industry is grown rapidly in recent years, and new-energy automobile steps into common people family, a large amount of core component battery,
Efficient laser welding has been all made of in copper electrode and the production of automobile busbar connector and process.
Laser welding is a kind of novel welding technique.Feature is that welded part deformation is small, and depth-to-width ratio is high, heat affected area
It is small, therefore welding quality is higher than traditional welding method: i.e. speed is fast, and depth is big, and deformation is small, and internal sensitive member can be effectively protected
The injury that part and integrated circuit, microcircuit are not heated is particularly suitable for the welding of 3mm or less thin-wall metal, the achievable 0.2mm of minimum
Thin walled welds, while be suitable for dissimilar material between splicing weldering, penetrate welding processing.Early stage method for laser welding is generally
Welding focal length is fixed, and the part welding of different-thickness will do process test, and process is complicated, and focal length parameter is adjusted after need to being gone out with dipstick metering
Whole, the solder joint that a workpiece has multiple height different can't once weld completion, and working efficiency is low, unstable product quality.
With the continuous improvement of product quality and output demand, domestic enterprise constantly improve technological equipment, especially to electricity
Pole weldquality requires to further increase, it is desirable that the dimensional discrepancy of the adaptive workpiece to be welded of laser welding apparatus.Due to different
Focal position will make the laser power density variation of effect on the surface of the material very greatly, so that the influence to weldquality is very big.It is logical
The variation for crossing research discovery welding focal position will all have a great impact to weld penetration, molten wide and section of weld joint are long-pending,
So simultaneously adjust automatically just has urgent demand to the servo-actuated detection of focusing, welding focometry is carried out to each solder joint, is protected
Demonstrate,prove the consistency of each solder joint welding quality.
In order to study focal length follow-up method, according to the design feature at laser welding position, our company fills before laser welding
Folder, welding procedure are deeply practiced.By improve twice with it is perfect, measuring device in conjunction with hold-down mechanism, measurement result is real-time
It is transferred to control system, control system does corresponding amendment to laser welding.Meet the requirement of laser welding focal length consistency.
The focal length of laser welding is servo-actuated testing agency and has the following characteristics that 1) wide adaptability, can be adapted for the weldering of various plane types
Stitch focal length detection；2) structure novel will test by tracking measurement plate and be a little transformed into measurement plate using transition measurement method,
Small space is avoided to measure inaccurate problem, measurement accuracy reaches 0.003mm；3) flexible for installation, which both can be with
It is installed on vertical straight-line displacement slide unit, the 6th axis of robot can also be installed on.
Utility model content
The purpose of this utility model is to provide a kind of focal lengths for laser welding to be servo-actuated testing agency, is applied to automobile
The laser welding of electric appliance carries out welding focometry to each solder joint in laser beam welding and compensates, guarantees each solder joint
The consistency of focal length.The utility model discloses a kind of focal lengths for laser welding to be servo-actuated testing agency, it is characterised in that:
(1) focal length is servo-actuated testing agency and is made of integrated support plate, detection pressure head, tracking measurement plate, servo-actuated slide unit, distance measuring sensor,
Distance measuring sensor is installed on integrated support plate upper right side, and servo-actuated slide unit is installed on integrated support plate lower left, and tracking measurement plate is visited
Pressure-measuring head is installed on servo-actuated slide unit and with slide unit synchronizing moving；(2) detection pressure head acts on weldment bond pad locations, ranging sensing
Device measures tracking measurement Board position offset；(3) distance measuring sensor uses non-contacting Laser Displacement sensor, high-acruracy survey
And weldment bond pad locations are fed back, it measures in due course and focal length is welded in compensation automatically.The focal length of laser welding is servo-actuated testing agency's peace
Dress flexibly, can cooperate welding laser head to combine with multi-axis robot, industrial mould group；Below with reference to the mechanism in " laser welding
The utility model is described in further detail for application in equipment ".
Detailed description of the invention
Fig. 1 is that the focal length of the utility model laser welding is servo-actuated testing agency's assembling schematic diagram, is mainly formed: detection pressure
