Embodiment 1
A kind of dmd chip angle adjuster, as shown in Figure 1, including DLP circuit board 1 and chip slot 2, the DLP circuit board
1 lower part is provided with adjustment tank 4, and the opening at 4 top of adjustment tank is square hole 3, the square hole 3 and 2 shape of chip slot
Match, as shown in Fig. 2, being equipped with slide plate 6 on the outside of the long side of the square hole 3, described 6 one end of slide plate is provided with through-hole, passes through spiral shell
It follows closely the through-hole across described 6 one end of slide plate and is screwed into the threaded hole on 3 side of square hole, it can be by slide plate 6 and DLP electricity
Road plate 1 is fixed, after unscrewing the screw, slide plate 6 can be made to rotate around the axis of screw, be arranged inside the adjustment tank 4
There is telescopic rod 7, the bottom surface of the adjustment tank 4 is fixed in 7 lower end of telescopic rod, and 7 upper end of telescopic rod passes through bulb 8 and institute
The connection of chip slot 2 is stated, the upper surface of the bulb 8 is fixedly connected with the chip slot 2, and 3 two sides of square hole are provided with position
