Description

Technical Field

[0001] This application relates to a card pushing method, apparatus, device, and computer-readable storage medium, belonging to the field of card sorting machine technology. Background Technology

[0002] The improvement of living standards has led to an increasing demand for leisure and entertainment. More and more people are choosing automatic tile sorting machines over manual ones for entertainment. Taking a mahjong machine as an example, the following explains the role of the tile-pushing head. The tile-pushing head is responsible for pushing the mahjong tiles out of the shuffling tank and neatly stacking them on the table. Initially, the tile-pushing head is at the outer tile-pushing opening, ready to push tiles onto the tile-receiving plate. The tile-receiving plate first receives the first mahjong tile at its highest point, then lowers to its lowest point to receive the second tile, and then rises back to its highest point, where the stacking tile pusher pushes the two tiles to their designated positions. During this process, the rising and falling motion of the tile-receiving plate needs to be coordinated with the movement of the tile-pushing head to ensure that the mahjong tiles are pushed out accurately and stably. When a certain number of mahjong tiles, such as 13, are pushed, the control system issues a command, causing the tile-pushing head to move to the inner tile-pushing opening and begin pushing the tiles. During this process, the speed, force, and direction of the tile-pushing head's movement need to be precisely controlled to ensure that the mahjong tiles are pushed out neatly and stably. In the process of pushing mahjong tiles, the stacking motor plays a crucial role. It drives the pusher head to move up and down, pushing and stacking the tiles. Simultaneously, the stacking motor needs to work in conjunction with the control system, adjusting the pushing speed and force based on real-time feedback to adapt to different game scenarios and needs. In existing tile pusher implementations, the tiles have already been identified and flipped; the pusher head pushes tiles face down and back up. That is, flipping and pushing are two independent and continuous actions. This method is slow. Currently, there is no method or device that can combine pushing and flipping to improve tile arrangement speed. Summary of the Invention

Detailed Implementation

[0024] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0025] Example 1, Reference Figures 1-3 This embodiment describes a card-pushing method, which includes the following steps: Step 1: When the card game 1 moves to the pushing position or during the process, identify the front and back information of the card game 1. The method is as follows: Step 1: Set up an identification device 2 at the position where the card game 1 moves to or along the path of the card game 1; when the card game 1 passes the identification device 2, the identification device 2 collects the passing signal of the card game 1 and transmits the collected signal to the control module. The chessboard 1 can be a magnetic chessboard, a non-magnetic chessboard, a chessboard with an excitation material adhered to the grooves in the lettering on the front or the back of the chessboard, a chessboard with an excitation material mixed with a non-metallic medium coating and adhered to the grooves in the lettering on the front or the back of the chessboard, or a chessboard with a sensor marker inside. A magnetic chessboard refers to a chessboard with a magnet inside; a non-magnetic chessboard refers to a chessboard without a magnet inside. A chessboard with a sensor marker inside.

[0026] A board game with a sensor marker inside refers to a board game where an identification groove is made on the edge of the board game, and a sensor marker is placed in the identification groove; the sensor marker is a magnet or a metal body.

[0027] The identification groove is vertically located in the middle of the board game 1, or horizontally located in the middle of the board game 1; or located diagonally on the board game 1.

[0028] A sensor marker is placed in the recognition groove in the middle of the chess and card game board.

[0029] A sensor marker is placed in the horizontal recognition groove in the middle of the card game board.

[0030] A sensor marker is placed in the recognition groove at the diagonal position of the card game board.

[0031] The excited material is a fluorescent material coating, a phosphorescent material coating, a luminescent material coating, or a cold light material coating.

[0032] Non-metallic media materials include organic material coatings and inorganic non-metallic material coatings; The organic material coating is a hydrogel coating, an organic adhesive coating, a synthetic resin coating, or a synthetic rubber coating; Inorganic non-metallic material coatings are made of silicate adhesives, phosphate adhesives, or oxide adhesives.

[0033] The identification device 2 is a color sensor, a photosensor, a contact identification device, or a non-contact identification device 2.

[0034] The non-contact identification device is a linear variable differential transformer, a laser rangefinder, an ultrasonic detector, a photoelectric sensor, or a machine vision system.

[0035] The contact identification device is a coordinate measuring machine, an articulated arm measuring machine, an inductive sensor, a capacitive sensor, a potentiometer sensor, or a linear displacement sensor.

[0036] Step 1 and 2: Identification device 2 collects data on the front or back of the chess piece 1; In this embodiment, only one type of identification device 2 is described; other devices with similar principles will not be described in detail. Specifically, when the identification device 2 is an ultrasonic detector, the ultrasonic detector includes an ultrasonic generator and an ultrasonic receiver. The ultrasonic transmitter emits ultrasonic waves to the card 1, and the ultrasonic receiver receives the echo of the ultrasonic waves. If the echo detection is a plane, then the back of the card 1 will be detected. If the echo body is a plane but there is noise, then the detection surface is the front of the card 1. The noise is the echo of the pit on the front of the card 1. In this way, the front and back of the card 1 can be detected, and then the front and back signals can be transmitted to the control module.

[0037] Specifically, when the card game 1 has excitation material adhering to the groove of the lettering on the front or the back of the card game, and the identification device 2 is a photosensitive device, the card game with excitation material is excited by the excitation device, enabling the excitation material to be identified by the photosensitive device. When the card game 1 has excitation material adhering to the groove of the lettering on the front, when the card game 1 passes by the photosensitive device, the photosensitive device will generate two signals: a photosensitive signal and a non-photosensitive signal. When the photosensitive device senses the excitation material, the detection surface is the front of the card game 1, and the photosensitive signal is transmitted to the control module. When the photosensitive device does not sense the excitation material, the detection surface is the back of the card game 1, and the control module does not receive a signal.

[0038] Specifically, when the recognition device 2 is a color sensor, it can identify the front and back of the mahjong tile by utilizing the color difference between the front and back, or by utilizing the difference between the long blank area on the front of the tile, the long colored area on the back, the colored area or white area on the long side, or the colored area or white area on the wide side. This is because the color of the front and back of the tile is different, and the back of the tile has a colored layer with a thickness of 2mm. The colored layer appears as a colored block close to the back on the side of the tile. The color sensor can identify the front and back of the mahjong tile by distinguishing the position of the colored block on the side, or it can directly identify the front and back of the tile by utilizing the color difference between the front and back.

[0039] Step 13: Determine the front or back of the card game 1 based on the collected front or back data; Based on the received signal, the control module can determine the front and back information of the chess piece 1. The specific determination method is the same as the recognition process of the recognition device 2 in steps one and two.

[0040] Step Two: When Card 1 moves to the pushing position, perform the pushing or 180-degree flipping action based on the front / back information of Card 1. The method is as follows: Step 2: The control module receives the front and back signals of the chess piece 1 transmitted by the identification device 2; Step 22: The control module receives the arrival signal of chess piece 1; Steps 2 and 3: The control module controls the execution mechanism 6 to perform the action of pushing the card or flipping the card 1 according to the front and back information of the card 1. The method is as follows: when the control module receives the information that the card 1 is face down, it controls the execution mechanism 6 to perform the action of pushing the card; when the control module receives the information that the card 1 is face up, it controls the execution mechanism 6 to perform the action of flipping the card. After the card flipping action is completed, it controls the execution mechanism 6 to perform the action of pushing the card.

[0041] When the control module controls the actuator 6 to perform the action of pushing the card or flipping the card 1 according to the front and back information of the card 1, the card is placed on a flat surface with friction or in a groove that can accommodate the card, which helps the card to complete the pushing action. Specifically, the actuator 6 consists of a motor 61 driving two actions. The actuator 6 includes: a motor 61, a first drive wheel 62, a second drive wheel 63, a first drive block 64, a card pushing mechanism 65, and a card flipping mechanism 66. The motor 61 is connected to the first drive wheel 62, and the first drive wheel 62 is connected to the second drive wheel 63. The second drive wheel 63 is coaxially connected to the first drive block 64. The first drive block 64 is connected to the card pushing mechanism 65; The second drive wheel 63 is connected to the card-flipping mechanism 66; The motor 61 drives the first drive wheel 62 to rotate forward and in reverse; When the motor 61 drives the first drive wheel 62 to rotate in the forward direction, the first drive wheel 62 drives the second drive wheel 63 to rotate in the forward direction, the second drive wheel 63 drives the first drive block 64 and the second drive block to rotate in the forward direction, and the first drive block 64 drives the card flipping mechanism 66 of the actuator 6 to perform the card flipping action. When the motor 61 drives the first drive wheel 62 to rotate in the opposite direction, the first drive wheel 62 drives the second drive wheel 63 to rotate in the opposite direction, the second drive wheel 63 drives the first drive block 64 to rotate in the opposite direction, and the first drive block 64 drives the card pushing mechanism 65 of the actuator 6 to perform the card pushing action.

[0042] Example 2, Reference Figures 4-5 This embodiment differs from Embodiment 1 in that the actuator 6 includes a first motor, a second motor, a rotating mechanism, and a card-pushing part; the first motor drives the rotating mechanism to rotate 180 degrees; the second motor drives the card-pushing part to perform a card-pushing action. The rotating mechanism is provided with a groove for accommodating the playing cards, which helps the playing cards to push the cards; The rotating mechanism has a platform for holding the chess pieces, and the surface of the platform has friction, which helps the chess pieces to push the cards.

[0043] Example 3, Reference Figures 6-11 This embodiment describes a card-pushing device, comprising: an identification device 2, a first positioning module 3, a second positioning module 4, a third positioning module 5, an actuator 6, and a control module; The output terminals of the first positioning module 3, the second positioning module 4, the third positioning module 5, and the identification module are connected to the input terminal of the control module; the output terminal of the control module is connected to the input terminal of the actuator 6. The first positioning module 3 is used to obtain the positioning signal of the chess piece 1; The second positioning module 4 is used to acquire the card-pushing signal from the actuator 6. The third positioning module 5 is used to obtain the signal that the actuator 6 has flipped the card into place.

[0044] During the movement of the card game 1, the identification device 2 identifies the front and back signals of the card game 1 and transmits the collected signals to the control module. When the card game 1 moves to the first positioning module 3, the first positioning module 3 transmits the collected positioning signal of the card game 1 to the control module. The control module controls the actuator 6 to perform actions according to the signals transmitted by the identification device 2. When the identification signal received by the control module is the front of the card game 1, the control module controls the actuator 6 to perform a card pushing action. The second positioning module 4 collects the positioning signal of the actuator 6 and transmits it to the control module. The control module controls the actuator 6 to stop its action. At this time, the actuator 6 has completed the card pushing action. When the identification signal received by the control module is the back of the card game 1, the control module controls the actuator 6 to perform a card flipping action. The third positioning module 5 collects the positioning signal of the actuator 6 and transmits it to the control module. The control module controls the actuator 6 to stop its action. At this time, the actuator 6 has completed the card flipping action.

[0045] In practical applications, the first positioning module 3, the second positioning module 4, and the third positioning module 5 can be set at the corresponding positions according to actual needs.
