Abstract
The utility model relates to a laser welding head, which can realize non-contact welding by using a laser in order to reach a fine precision welding effect with high standard and high quality. The laser and a coaxial observation CCD video optical path are combined, high-performance image processing software and a laser positioning sensor are combined to process microminiature welding positions, and thus welding positions and heights can be corrected and various PCB substrates can be processed flexibly. During usage, the laser enters via a laser seat 8, goes through a collimating mirror 9, passes a reflector 10, enters a focusing lens 2, and focuses on a work surface. Visible light enters the focusing lens 2 via the work surface to be collimated, goes through 3, 4, 5 and 6, and reaches to CCD 7 for imaging.
Description
Technical field
The utility model relates to technical field of welding equipment, is a kind of laser weld head unit.
Background technology
Amount reaches 3.49 hundred million tons, become steel production and country of consumption the biggest in the world, and welded steel using amount is also broken through 1.3 hundred million tons, is equivalent to the output of steel in 1 year of the U.S., becomes unprecedented in the world maximum welded steel structure manufacturing nation.Some landmark projects of China's completion in recent years, solder technology has been brought into play important function.
Existing plumb joint is normally to the perhaps welding of simple non-closed curve weld seam of spot welding, straight bead.The utility model plumb joint can retrofit PCB circuit board, adopts optical fiber laser as light source, through custom-designed optical system, makes laser be focused to the hot spot of size about 0.2mm, can weld small paster electronic devices and components.Simultaneously in light path, be designed with coaxial CCD video image acquisition system, can be to processing welding monitoring in real time.
Summary of the invention
The problem that the utility model will solve is: with laser weld high accuracy pcb board electro-optical system.
The technical scheme of the utility model is: laser welding system it by collimating mirror, speculum, spectroscope, amasthenic lens, CCD camera lens, laser energy adjuster, electronic beam expanding lens, welding base, compositions such as mirror unit.
The optical fiber laser emitting laser passes through collimating mirror; Outgoing becomes approximate directional light; Through two speculums, a back speculum is a spectroscope again, and laser gets into amasthenic lens; Laser forms the hot spot about 0.2mm at the focal plane of amasthenic lens, and concentrated energy focuses on the workpiece pcb board to be processed.Spectroscopical effect is that the imaging light on the workpiece pcb board is passed through, and through the CCD camera lens, the parts of images of processing is imaged on the CCD, provides the video image of monitoring to supply the operator to observe.
In the optical system design, adopt aspheric surface technology or binary optical technique, to reach excellent hot spot focusing quality.Simultaneously, the employing of binary optical technique can be satisfied the consistent requirement of optical system different wave length light focusing, can increase the pilot light of Laser Processing, guides Working position.More tiny welding laser facula can satisfy the needs of the precision welding connection technology of small paster electronic devices and components.
In General layout Plan, can increase energy regulator and electronic beam expanding lens as required.Electronic beam expanding lens is used to control the size of focal beam spot, can be directed against the different surface mount elements of solder joint, in real time automatically the size of the hot spot that focuses on of adjustment laser reach 0.2mm+/-0.1mm, can also adjust operating distance.Simultaneously, another innovative point is in order to adjust the power of laser energy, in system, to select to add the laser energy adjuster, realizing that the energy of step-less adjustment Laser Processing is strong and weak.
The utility model is to utilize laser, realizes contactless welding, to reach the effect of high standard, high-quality fine accurate welding.And laser combines with coaxial-observation CCD video light path; The microminiature welding position is combined to handle through high-performance image process software and laser positioning sensor; Make welding the position, highly revise, can handle corresponding various types of PCB substrate flexibly.

The specific embodiment
As shown in Figure 1, the utility model comprises welding base 1, focus lamp 2, body element 3, right cover plate 4, upper cover plate 5, CCD camera lens 6, CCD7, laser bench 8, collimating mirror 9, speculum 10.
Wavelength is that the laser of 808nm is got into by laser bench 8, becomes approximate directional light through collimating mirror 9 outgoing, through speculum 10, gets into amasthenic lens 2 and focuses on, and focus drops on the working surface.Visible light gets into focus lamp 2 by working surface and is reached the CCD7 imaging by collimation through 3,4,5,6.
The utility model can increase energy regulator and electronic beam expanding lens as required in practical application.Electronic beam expanding lens is used to control the size of focal beam spot, can be directed against the different surface mount elements of solder joint, in real time automatically the size of the hot spot that focuses on of adjustment laser reach 0.2mm+/-0.1mm, can also adjust operating distance.Simultaneously, can be chosen in adding laser energy adjuster in the system, the power of adjustment laser energy realizes that the energy of step-less adjustment Laser Processing is strong and weak.
