Embodiment 1
[0092] Next, various embodiments of the present invention will be described with reference to the drawings.
[0093] like figure 1 As shown in (a) to (e), in the workpiece bonding method according to Example 1 of the present invention, the adhesive 3 is sandwiched between the workpieces 1 and 2 in a rectangular shape smaller than the outer shapes of the workpieces 1 and 2 . As a plurality of light-shielding masks 4 with different light-transmitting shapes, in the first step in the main curing process, a first light-shielding mask 41 having a first light-shielding pattern 4a with a frame-shaped light-transmitting hole 4h opened is used. In the next second time, use the second light-shielding mask 42 having the second light-shielding pattern 4b opened with the rectangular light-transmitting hole 4h to divide the divided regions 3b and 3c of the adhesive 3 into two times, sequentially and respectively. Perform partial formal curing.
[0094] That is, with respect to the frame-s...
Embodiment 2
[0104] like image 3 (a)~(e) and Figure 4 As shown in (a) and (b), in the workpiece bonding method according to Example 2 of the present invention, as various kinds of light-shielding masks 4 with different light-transmitting shapes, in the first time of the main curing process, use Have the first light-shielding mask 41 of the first light-shielding pattern 4a that is opened with the X-shaped light-transmitting hole 4h along the diagonal line of the rectangular adhesive 3, in the next second time, use the first light-shielding mask 41 that has the X-shaped light-transmitting hole 4h that is opened with The second light-shielding mask 42 of the second light-shielding pattern 4b of the (4) triangular light-transmitting holes 4h sandwiched by the diagonals of the rectangular adhesive 3 divides the divided regions 3b and 3c of the adhesive 3 twice , sequentially, respectively, for partial formal solidification, this structure is the same as figure 1 and figure 2 The example 1...
Embodiment 3
[0110] like Figure 5 As shown in (a) to (e), in the workpiece bonding method according to Example 3 of the present invention, as a plurality of types of light-shielding masks 4 with different light-transmitting shapes, in the first step of the main curing process, a Have the first light-shielding mask 41 of the first light-shielding pattern 4a that is opened with the frame-shaped light-transmitting hole 4h, in the next second time, use the first light-shielding mask 41 that has the light-shielding pattern 4h that is opened with the square black-and-white checkered shape. The second light-shielding mask 42 of the second light-shielding pattern 4b, in the next third time, use the third light-shielding mask 43 of the third light-shielding pattern 4c having the light-transmitting holes 4h of the square black and white checkered pattern, The divided regions 3b, 3c, and 3d of the adhesive 3 are divided into 3 times, sequentially, and partially formally cured respectively.
