Description

Automatic lottery device

Technical field

Prize drawing device is the utility model is related to, specially a kind of automatic lottery device.

Background technology

Existing prize drawing device is broadly divided into two classes, and one kind is manual identified winning results；Such device turns by prize drawing Disk rotates, and mostly structure is relatively easy, but due to being eye recognition winning results, lacks presence during use.It is another kind of It is that there is prize-winning voice, the automatic lottery device of video image prompting, such prize drawing apparatus structure is more complicated, use reliability phase To poor.

The content of the invention

The problem of the utility model solves existing automatic lottery apparatus structure complexity, and use reliability is relatively poor, A kind of automatic lottery device is provided, more rationally, simply, use is more reliable for automatic lottery apparatus structure design.

The utility model adopts the following technical scheme that realization：Automatic lottery device, including base, support, awards disk, Pointer, motor, U-shaped photoelectric sensor, encoder and the control circuit in base, support are supported on base, awards Disk is fixed on support front portion, and the center of awards disk is provided with circular hole, and pointer includes the rotating shaft that rear end is provided with axis hole, and rotating shaft front portion is set There is the pointer vertical with rotating shaft, rotating shaft rear portion is provided with triggering pin coordinate with U-shaped photoelectric sensor and vertical with rotating shaft, rotating shaft Phase of the anterior pointer with the triggering pin at rear portion on shaft circumference is identical（To ensure the clearing position of awards disk and U-shaped light Electric transducer trigger position is consistent）；Motor is fixed on support rear portion, and the rotating shaft of pointer passes through the circular hole of awards disk center and led to The shaft hole sleeve crossed thereon is fixed in the rotating shaft of motor, while after pointer is located at before awards disk, triggering pin and be located at awards disk Face, U-shaped photoelectric sensor are fixed on support and are engaged with triggering pin, and encoder is arranged in the rotating shaft of motor；Control electricity Road includes controller, and the input of controller is connected with the key switch being placed on base panel, U-shaped photoelectric sensor and coding The output end of device is connected with the input of controller, and the output end of controller is connected with motor, and the output end of controller is also connected with There are loudspeaker and display screen, display screen is placed on base, and controller is also associated with being stored with voice corresponding with awards, regarded The memory of frequency evidence.

During work, the key switch on base panel is pressed, controller receives key switch and presses signal, in corresponding software Under support, controller controlled motor rotates, and then drives the encoder on pointer and machine shaft to rotate simultaneously, encoder meeting To controller, the pulse signal that controller inputs to encoder counts continuous output pulse signal, touching on pointer Hairpin often triggers a U-shaped photoelectric sensor, and U-shaped photoelectric sensor sends signal to controller, and controller receives U-shaped photoelectricity The signal that sensor is sent, the pulse signal of encoder input is carried out counting clearing and started counting up again；Button is unclamped to open Close, after controller receives key switch release signal, the stalling of controller controlled motor；Turned around and exported by encoder rotation Pulse sum be fixed, the umber of pulse on awards disk shared by each awards area is fixed, encoder received by controller Pulse signal quantity combination awards disk on number of pulses shared by each awards area, controller just calculates pointer meaning Awards, then controller read memory in voice corresponding with prize-winning awards, video data, and give respectively loudspeaker and Display screen, e.g., loudspeaker play " first prize television set ", and display screen shows the video content about the television set.To be further Use reliability is improved, pointer rear portion is fixed with magnet, and the Hall sensor triggered by magnet, hall sensing are fixed with support The output end of device is connected with the input of controller, and fixed position of the Hall sensor on support ensures triggering pin triggering U-shaped While photoelectric sensor, magnet just triggers Hall sensor.So, by dual trigger, dual fail-safe is realized, is made so as to reach With reliable purpose.

The utility model, which employs pointer and turned dynamic rather than awards disk, is turned dynamic mechanical structure, simplifies production Product structure.Control circuit has selected suitable sensor, makes the rational in infrastructure, simple of control circuit；Employ double-sensing simultaneously The dual trigger control structure of device, improve the use reliability of product.The utility model design more rationally, it is simple, using more may be used Lean on.
