Laser line light source assembly and assembly method thereof
Technical field
The present invention relates to a kind of laser line light source assembly and assembly method thereof.
Background technology
Laser level is a kind of being used for to build the Laser emission instrument that can obtain horizontal plane, vertical plane and horizontal line, vertical line with indoor and outdoor decoration operation through laser beam, and wherein one of technology of core is exactly the laser line light source assembly of high-quality, high reliability.Except the use on laser level, the laser line light source assembly also is widely used in the cutting indication of various sheet materials such as steel, timber; The textile industry various device is walked the line position indication; Security area light curtain is kept watch on; High ferro rail linearity noncontact inspection; The tool setting of machining equipment; Numerous areas such as Medical Devices inspection area indication.
The operation principle of laser line light source assembly such as Fig. 2-3, and the laser beam of laser instrument output forms a bright line through a cylindrical lens 1 back on metope 2; Wherein, when the central axis of said laser beam and cylindrical lens was vertical, the bright line on the said metope was a straight line 3; Otherwise be camber line 4.
Like Fig. 1; Existing laser line light source assembly comprises: adopt toughness preferably aluminium through the hollow cylinder of machined moulding; In the main part 5 of hollow cylinder the laser generating assembly is set, the contiguous block 7 through a pair of radial symmetric between the main part 5 of hollow cylinder and the top ends 6 links to each other; The end face center of said top ends 6 is provided with light hole 8, and the sidewall of top ends 6 is provided with the through hole 9 that radially runs through, and said cylindrical lens 1 wears and is fixed on this in the through hole 9; The end face of said top ends 6 is provided with two pairs of screw holes 10 that are symmetrically distributed in said a pair of contiguous block 7 both sides; During assembling and setting,, finely tune the central axis of said cylindrical lens 1 and the angle of said laser generating assembly outgoing laser beam, and to make its angle be the right angle through adjusting the screw in said two pairs of screw holes 10.
The weak point of above-mentioned graticule appearance of the prior art is: special construction of (1) said hollow cylinder 5 and assembling and setting mode; Aluminium is through machined moulding (can't adopt more firmly, more crisp cast aluminium realize this structure through the mode of one-step casting moulding) preferably to make it must adopt toughness, and processing cost is higher, production efficiency is lower; (2) adopt four screws to adjust the central axis of said cylindrical lens 1 and the angle of said laser generating assembly outgoing laser beam, debugging difficulty is bigger; (3) after assembling and setting is accomplished; There is mechanical stress in contiguous block 7 places of laser beam modulation head assembly; Cause above-mentioned existing laser line light source in use, said top ends 6 is prone to take place the situation of loosening or flow of metal, and then to cause the central axis of said cylindrical lens 1 and the angle of said laser generating assembly outgoing laser beam be not the right angle; And then causing the laser rays of laser line light source output to demonstrate arc, influence is used.

The bottom surface central authorities of said fitting recess are provided with central through hole, so that the said cylindrical lens of laser beam directive of said laser generating assembly output.
The assembly method of above-mentioned laser line light source assembly comprises the steps:
A, the laser generating assembly is fixed in the main part, and makes the laser beam of laser generating assembly output be suitable for all passing said central through hole;
On B, the said a pair of inclined-plane in said fitting recess said cylindrical lens is set radially;
C, on the end face of said top ends fixing elastic spring, to compress said cylindrical lens;
D, this laser beam modulation head assembly is fixed on the debugging frame, and makes this laser beam modulation head assembly towards a metope; Debugging frame is provided with pair of screws, and this is located at the right ends of said cylindrical lens in opposite directions to screw, and is suitable for that this adjusts the left and right sides position of cylindrical lens on said a pair of inclined-plane to screw through synchronous rotation;
The power supply of E, the said laser generating assembly of connection,, and on said metope, generate a bright line; When this bright line was protruding camber line to the right, the said pair of screws of synchronous micro-adjusting also made cylindrical lens displacement to the right; Otherwise, then control the displacement to the left of said cylindrical lens; When the bright line on said metope was straight line, debugging finished.
F, unclamp the above pair of screws of debugging frame then, laser beam modulation head assembly is taken off from debugging frame, between the bottom surface of the two ends of cylindrical lens and said fitting recess, adopt glue fixing.
Technique scheme of the present invention is compared prior art and had the following advantages: (1) laser line light source assembly of the present invention is adjusted the central axis of said cylindrical lens and the angle of the laser beam that said laser generating assembly is exported through a pair of inclined-plane; Adopt the method for four screws adjustment with respect to prior art, that the present invention has is simple in structure, adjustment accuracy is higher, convenient directly perceived, the characteristics such as debugging difficulty is less of debugging, so be suitable for significantly reducing cost of labor.(2) laser line light source assembly of the present invention is simple in structure; Be suitable for adopting the cast aluminium one-step die casting; Compare with the mach mode of available technology adopting, the present invention has characteristics such as production cost is lower, production efficiency is higher, precision is higher, product quality is easy to control.(3) after cylindrical lens of the present invention adopts glue fixing, have mechanical stress hardly, so reliability of products is higher.(4) assembly method of laser line light source assembly of the present invention, step is simple, reliability is higher, labour intensity is lower and be easy to grasp, is suitable for significantly reducing labor hour.
