Detailed Implementation

[0033] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0034] Example: Intelligent voice-controlled card dealing machine, including base 1 and housing 2 rotatably mounted on base 1. Housing 2 consists of an outer shell and a bottom plate 74. The bottom of bottom plate 74 is provided with a plug shaft. The plug shaft is connected to a fixed gear 18 inside base 1 through a rotary bearing 69. The inner ring of rotary bearing 69 contacts the outer wall of plug shaft, and the outer ring of rotary bearing 69 contacts the inner wall of fixed gear 18. The housing 2 is provided with an operation panel 3, which includes a display screen and operation buttons. The housing 2 is provided with a main control circuit board 21. The bottom of base is provided with a detachable base cover plate 73. The bottom of base 1 is provided with multiple anti-slip pads 70.

[0035] The housing 2 contains a main component 4, which houses a first motor 5 for rotating the housing 2 around its central axis. A card compartment 6 is located at the rear of the top of the housing 2, and a card-pressing rod 7 is hinged within the card compartment 6. A counterweight 11 is located at the end of the card-pressing rod 7 furthest from the housing 2. A card-dispensing port 8, communicating with the card compartment 6, is located on the front of the housing 2. Inside the housing 2 are upper card-dispensing components 9 and lower card-dispensing components 10, respectively located on the upper and lower sides of the card-dispensing port 8. The outer shell of the housing 2 is attached to the base plate 74 with screws. For easy and quick assembly and disassembly, the main component 4 has a card-dealing reduction gearbox 12 on one side. The input end of the card-dealing reduction gearbox 12 is connected to a second motor 13, and the two output ends of the card-dealing reduction gearbox 12 are respectively connected to a card-pushing rubber roller 14 and a card-dispensing rubber roller 15. The output power of the second motor 13 is transmitted to the card-pushing rubber roller 14 and the card-dispensing rubber roller 15 through the card-dealing gearbox 12, causing them to rotate. The top of the card-pushing rubber roller 14 extends into the card compartment 6, and the top of the card-dispensing rubber roller 15 extends to the card-dealing opening. Within the card dispenser 8, friction is used to move the playing cards in the card magazine 6 onto the card dispensing roller 15 via the card dispensing roller 14. The card dispensing roller 15 then dispenses the playing cards from the card dispenser 8, achieving automatic card dealing. Photoelectric sensors 16 are installed on both the upper and lower sides of the card dispenser 8 to detect whether cards have been dealt and the number of cards dealt. A fixed gear 18 is fixedly connected to the bottom of the base 1 via multiple arc-shaped grooves 17 and screws. An over-pressure return spring 19 connects the base 1 and the fixed gear 18. The overall structure rotates clockwise or... When rotating counterclockwise, due to the gap between the gears, after the first motor 5 stops, the overall structure will wobble and overshoot along the circumference of the fixed gear 18 under the action of inertia. This will cause the fixed gear 18 to deflect slightly along the arc groove 17. At this time, the overshoot reset spring 19 will generate a pulling force in the opposite direction, thereby eliminating the wobble and overshoot of the overall structure. The first motor 5 is connected to the fixed gear 18 for transmission, so that after the first motor 5 starts, it will use the reaction force generated by the fixed gear 18 to drive the housing 2 to rotate.

[0036] The main component is equipped with a voice control assembly on its rear side. The voice control assembly includes a speaker 71 and a microphone 72 installed on the main component 4, which enables voice control operation, making it more convenient and faster.

[0037] The first motor 5 is equipped with an encoder assembly 20, which includes an encoder circuit board 75 and encoder circuit board sensing magnets 76. The number of Hall sensors on the encoder circuit board 75 is in a 1:2 ratio with the number of sensing magnets. Four magnets are evenly fixed on the circumference of the rotating structure at 90-degree intervals, forming a 360-degree periodic distribution of magnetic poles, arranged in alternating polarity (NSNS), forming complementary signal triggering logic. Based on the time difference and magnetic field strength change rate of the signals from the dual encoder circuit boards, orthogonal decoding is performed. The phase difference between the two signals is automatically identified using the MCU hardware encoder interface to determine whether the rotation direction is forward or reverse. Pulse counting mapping is used, and each detection of four magnet cycles corresponds to a 90-degree mechanical angle. An accumulator is used to achieve 360-degree closed-loop statistics. Based on the rising edge time difference of the two Hall signals, the instantaneous angular offset when the magnet passes is calculated with a resolution of ±0.5 degrees. The sinusoidal relationship curve between magnetic flux density and angle is pre-stored, and nonlinear errors are corrected by a lookup table method. This, in conjunction with the overshoot reset spring 19, achieves precise control of the 360-degree rotation angle. The photoelectric sensor 16, encoder assembly 20, second motor 13, and first motor 5 are all connected to the main control circuit board 21 via signal connection.
