Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: an A-type backlight module lighting pressing device, comprising a workbench 1, an opening and closing mechanism is installed above the workbench 1 for lighting operation, and the opening and closing mechanism includes:

[0026] The intermittent unit 2 is installed in the inner cavity of the workbench 1. The intermittent unit 2 includes a rotating plate 21 installed in the inner cavity of the workbench 1. The side of the rotating plate 21 is fixedly connected with teeth 22 at equal intervals, and the teeth 22 are distributed on the lower half of the rotating plate 21. A gear 23 is installed above the rotating plate 21. The gear 23 is rotatably connected to the rotating plate 21 through the teeth 22, and the number of teeth of the gear 23 is equal to the number of teeth 22;

[0027] The barrier unit 3 is installed in the inner cavity of the workbench 1, and is fixedly connected with teeth 22 at equal intervals on the side of the rotating plate 21. A gear 23 is installed above the rotating plate 21. The gear 23 is rotatably connected to the rotating plate 21 through the teeth 22, so that the gear 23 rotates intermittently driven by the rotating plate 21, which solves the problem that the light remains always on when in use, and long-term observation and identification will cause visual fatigue. Visual fatigue will cause unclear identification of the eyes, increase detection time, and easily lead to misjudgment, affecting production speed, and also causing energy waste and increasing production costs. The intermittent pressing switch is realized to reduce the labor intensity of workers, and the light can be turned on and off, avoiding long-term light exposure, which is beneficial to protecting the eyes.

[0028] In this embodiment, the blocking unit 3 includes a clamping plate 31 fixedly connected to the surface of the rotating plate 21 , and the clamping plate 31 is semicircular, and a clamping block 32 is fixedly connected to the surface of the gear 23 .

[0029] In this embodiment, a fixed shaft 4 is rotatably connected to the surface of the workbench 1, one end of the fixed shaft 4 passes through the surface of the workbench 1 and extends to the inner cavity of the workbench 1, and the part of the fixed shaft 4 in the inner cavity of the workbench 1 passes through the rotating plate 21 and the clamping plate 31 and is fixedly connected to the rotating plate 21 and the clamping plate 31.

[0030] In this embodiment, the inner cavity of the workbench 1 is rotatably connected with a rotating shaft 5 , the rotating shaft 5 is fixedly connected to the gear 23 , and the rotating shaft 5 passes through the surface of the clamping block 32 and is fixedly connected to the clamping block 32 .

[0031] In this embodiment, the surface opening of the workbench 1 is slidably connected with a pressing plate 6, which is a switch. When the pressing plate is pressed, the light comes on, and when the pressing plate is lifted, the light goes out. The lighting equipment is fixedly connected to the surface of the workbench. The surface of the pressing plate 6 in the inner cavity of the workbench 1 is provided with a sliding groove 7, and one end of the rotating shaft 5 is fixedly connected with a rotating rod 8, and the rotating rod 8 slides in the sliding groove 7.

[0032] In this embodiment, two rotating wheels 9 are installed on one side of the workbench 1, and the two rotating wheels 9 are rotatably connected by a conveyor belt 10. The fixed shaft 4 is fixedly connected to the nearest rotating wheel 9, and the other rotating wheel 9 is fixedly connected to a motor 11. One end of the output shaft of the motor 11 is fixedly connected to a rotating wheel 9 through a coupling. A clamping plate 31 is installed on the surface of the rotating plate 21, and the clamping plate 31 is semicircular. A clamping block 32 is fixedly connected to the surface of the gear 23. The clamping block 32 and the clamping plate 31 are in contact with each other during use to limit the position, thereby maintaining the stability of rotation. This solves the problem that the gear 23 loses the limit when rotating, resulting in automatic rotation due to inertia or reverse rotation due to gravity, causing irregular lighting of the light during use, increasing the detection time, increasing the probability of failure, and affecting the production and use experience. At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] When working, the external power supply starts the motor 11, and one end of the output shaft of the motor 11 drives the rotating wheel 9 to rotate through the coupling, and the rotating wheel 9 drives the rotating wheel 9 on the other side to rotate through the conveyor belt 10. At this time, the product is transported through the conveyor belt 10, and the rotation of the rotating wheel 9 drives the fixed shaft 4 to rotate, and the fixed shaft 4 drives the rotating wheel 9 to rotate. When the rotating wheel 9 rotates to the point where the teeth 22 are engaged with the gear 23, it drives the gear 23 to rotate. When the rotating wheel 9 rotates to the smooth side, the surface curvature of the clamping plate 31 fits with the concave portion of the surface of the clamping block 32, so that the gear 23 no longer rotates. When the gear 23 rotates, it drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the rotating rod 8 to rotate. The rotating rod 8 rotates in the slide groove 7 and squeezes the pressing plate 6, so that the pressing plate 6 slides up and down at the opening of the workbench 1, completing the automatic lighting operation, and the lighting speed is also proportional to the transmission speed of the conveyor belt 10, which can better carry out production.
