DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0020] Please refer to Figures 1-5 , the present utility model provides a technical solution: a signal acquisition structure of a rotary film rack fixing device, including a base 1. A central shaft 2 is provided in the middle of the base 1. A rotary disk module 3 is rotatably installed on the central shaft 2. The rotary disk module 3 rotates in the middle of the central shaft 2. A disk mounting frame 6 is installed on the top surface of the central shaft 2. Uniform mounting holes 7 are penetrated through the surface of the disk mounting frame 6. A sensor mounting bracket 8 is installed on the mounting hole 7. A diffuse reflection sensor 9 is installed on the sensor mounting bracket 8. The diffuse reflection sensor 9 collects the bottom end through an induction groove 13. When it rotates to the position where the induction groove 13 is opened, the signal of the diffuse reflection sensor 9 is blocked and there will be no induction interference to the non-detection object. A belt pulley 10 is fixedly installed at the center of the bottom surface of the rotary disk module 3. Uniform film rack loading positions 14 are provided around the side wall of the rotary disk module 3. Uniform induction grooves 13 are penetrated through the bottom surface of the rotary disk module 3. A starting position pin 16 is installed on the inner ring of the bottom surface of the rotary disk module 3. Uniform upper and lower loading position pins 11 are installed on the outer ring of the bottom surface of the rotary disk module 3. Two identical sensor bases 15 are installed on the base 1. A slot type opposed sensor 12 is installed in the inner cavity of the sensor base 15. The slot type opposed sensors 12 are respectively located directly below the starting position pin 16 and the upper and lower loading position pins 11.
[0021] Among them, a driving motor 4 is installed on the right side of the surface of the base 1. A belt 5 is installed on the output shaft of the driving motor 4. The other end of the belt 5 is installed on the belt pulley 10. The driving motor 4 drives the rotary disk module 3 to rotate through the belt 5. The distance between the diffuse reflection sensor 9 and the top of the rotary disk module 3 is less than the blind area distance of the diffuse reflection sensor 9. The position on the rotary disk module 3 where the induction groove 13 is opened can block the signal and there will be no induction interference to the non-detection object. The induction groove 13 is located at the center position of the top surface of the film rack loading position 14. The starting position pin 16 and the upper and lower loading position pins 11 are both installed corresponding to the center position of the film rack loading position 14. The data at the center position is more accurate.
[0022] Working principle: Through the simple structure of two slot type opposed sensors 12, the loading / unloading position pins 11 and the starting position pins 16, the acquisition of the starting position pins and the loading / unloading position pins of the turntable module 3 is realized. The processing of the pin holes, the procurement and installation of the pins are extremely convenient. Moreover, the pins are sensitively sensed by the sensors with high accuracy. Through the cooperation of multiple loading / unloading position pins 11 and starting position pins 16 with the slot type opposed sensors 12, the precise position sensing function is realized, solving the fixed-length motion function that needs high-precision motors such as stepper motors and servo motors, and eliminating the position offset error brought by the transmission system, reducing the material, processing, control and maintenance costs to a certain extent. Through the combination of the diffuse reflection sensor 9 and the slot type opposed sensor 12, two signals of position and state can be collected, improving the fault tolerance rate of signal acquisition to a certain extent. Utilizing the blind area characteristic of the diffuse reflection sensor 9, that is, the distance from the diffuse reflection sensor 9 to the top of the turntable module 3 is less than the blind area height. When the turntable module 3 rotates and its top rotates, when the diffuse reflection sensor 9 is blocked at the non-induction groove 13 opening, the diffuse reflection sensor 9 does not respond, effectively eliminating the induction interference of the diffuse reflection sensor 9 to non-detected objects and also making the sensor installation space smaller.
