Embodiment 1
As shown in figure 3, specific structure of the present invention are as follows: a kind of inclination joining method of scanning light source includes the following steps:
1., module light source determine, according to the calculating of scanning area, choose the module light source of suitable quantity and spot size；
2., light source incline, the module light source levels chosen are well placed, and the direction for keeping it vertical with scanning direction is into θ angle
Degree, θ are 10-60 degree, form it into three block scan regions, the delta-shaped region of intermediate parallel quadrilateral area and two sides；
3., light source splicing, the module light source for setting angle is spliced on scanning activity device, module light source splice when, make phase
The back side panel of two adjacent light source module mechanical covers is bonded with another front side board to be installed on scanning activity device, and makes
In the rectangular region of the same front and back trend of the delta-shaped region of two module light sources.
The product on working face 4 is scanned using above-mentioned spliced light source, two blocks of module light sources have sweeping for overlapping
Region is retouched, therefore the case where be not in gap and seam, due to energy on the individual module light source direction vertical with scanning direction
Amount distribution is successively rising-balance-decline, and the part for scanning overlapping experienced the twice sweep of adjacent block light source, therefore, two
The energy of the scanning area of block module light source overlapping can be balanced with other positions substantially, it is ensured that the effect of scanning.
Embodiment 2
A kind of inclination joining method of scanning light source as shown in Figure 4, includes the following steps:
