Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] See Figure 1-4 , a flip and reset mechanism for a darkroom absorbing material, comprising a main body component 1; the main body component 1 comprises a U-shaped plate 11, on the inner side of which is provided a plate body 12; an absorbing module 13, and both the plate body 12 and the top of the U-shaped plate 11 are provided with an absorbing module 13; a flip component 2 is provided on the U-shaped plate 11, and the flip component 2 comprises: a mounting plate 21, fixedly connected to the inner side of the U-shaped plate 11, and two are symmetrically provided; a rotating rod 22, rotatably connected to the opposite surfaces of the two mounting plates 21, and passing through one side of the mounting plate 21; a connecting block 23, fixedly connected to the outer side wall of the rotating rod 22; a gear 24, fixedly connected to one end of the rotating rod 22; a movable plate 25, Slidingly connected to the front surface of the U-shaped plate 11; rack 1 26, fixedly connected to the top of the movable plate 25, and meshing with the gear 1 24; a driving mechanism 27, arranged on the U-shaped plate 11; the driving mechanism 27 includes: a servo motor 271, fixedly connected to the front surface of the U-shaped plate 11; gear 2 272, fixedly connected to the output end of the servo motor 271; rack 2 273, fixedly connected to the bottom of the movable plate 25, and meshing with the gear 2 272; a baffle 4 is fixedly connected to the front surface of the U-shaped plate 11; a gravity sensor 5 is fixedly connected to the outer wall of the baffle 4, and the gravity sensor 5 is electrically connected to the servo motor 271.

[0028] When ready for use, the operator places the U-shaped plate 11 in the designated position. When a test is required, the operator drives the movable plate 25 to move in the direction close to the plate body 12 through the driving mechanism 27, so that the movable plate 25 drives the rack 1 26 to move at the same time. When the rack 1 26 moves, it drives the gear 1 24 to rotate, thereby driving the rotating rod 22 to rotate on the mounting plate 21 through the gear 1 24, so that the rotating rod 22 drives the plate body 12 to rotate through the connecting block 23, so that the plate body 12 drives the absorbing module 13 thereon to flip over, and then the movable mechanism can pass. When the test is completed, the operator controls the driving mechanism 27 to drive the plate body 12 to rotate in the opposite direction, without the need to re-lay, thereby improving the practicality of the device. The operator turns on the servo motor 271, so that the servo motor 271 drives the gear 2 272 to rotate, so that the gear 2 272 drives the rack 2 273 to move, and then the rack 2 273 drives the movable plate 25 to move. The operation is simple, which improves the convenience of the device; the baffle 4 can limit the movement range of the movable plate 25, and prevent the movable plate 25 from driving the rack 1 26 to disengage from the gear 1 24, thereby improving the stability of the device; when the movable plate 25 moves, it collides with the gravity sensor 5, and the gravity sensor 5 transmits an electrical signal to the distribution box, and the electrical signal is transmitted to the controller through the distribution box, and then the servo motor 271 is automatically turned off, and the operator does not need to manually turn off the servo motor 271, thereby improving the work efficiency of the operator.
