Description

Technical Field

[0001] This invention relates to the field of mahjong machine technology, and more specifically, to a mahjong machine with a tile-arranging function. Furthermore, this invention also relates to a method of using the aforementioned mahjong machine with the tile-arranging function. Background Technology

[0002] In the realm of leisure and entertainment, mahjong, as a popular traditional board game, has always seen its automation equipment evolve as a crucial direction for enhancing user experience. Traditional automatic mahjong machines, after years of development, can now effectively perform the two basic functions of shuffling and stacking tiles. This involves using an internal rotating mechanism to randomly mix the disorganized mahjong tiles, and then using a tile-lifting mechanism to push the neatly stacked tiles onto the table, thus replacing the tedious manual shuffling step and saving players time and effort.

[0003] However, even after solving the problems of shuffling and stacking cards, existing technical solutions still have functional limitations. First, before the game begins, players must manually take the neatly stacked cards in order according to the rules and arrange them in front of them. This process of taking cards is not only energy-consuming but also prone to human error, which can lead to disordered card order or exposure of card information, affecting the fairness and smoothness of the game. Furthermore, relying entirely on manual card handling, orderly arrangement of cards, and precise card placement poses a substantial barrier to participation for people with rheumatoid arthritis, Parkinson's disease, or other conditions that limit hand function, as well as for the elderly who experience cognitive decline and are prone to operational fatigue. This limits their social rights and psychological rehabilitation opportunities.

[0004] Meanwhile, the existing mechanical structure design of automatic mahjong machines is mainly based on simple rotation and pushing, lacking support for complex path planning and precise grasping actions, and is unable to handle the tasks of picking up and arranging tiles that require multiple degrees of freedom. With the accelerating pace of modern life, players are increasingly demanding convenience in their leisure and entertainment, hoping to obtain an immersive experience with full automation from shuffling and stacking tiles to picking up and arranging tiles.

[0005] In conclusion, how to improve the immersive experience of using mahjong machines is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a mahjong machine with a tile-arranging function, which can automatically arrange the tiles, allowing players to focus more on the game itself and enhance the immersive entertainment experience.

Based on the identification results and preset tile sorting rules, the controller controls the tile sorting mechanism to rearrange all the mahjong tiles on the temporary stop board into the tile sorting track in a preset order.

[0051] After the tiles are arranged, the controller controls the table body drive to rotate the table body mounting plate to the initial position, opening the tile outlet. The controller then controls the drive to output the mahjong tiles from the tile arrangement track and the tile drawing track from the corresponding tile outlets.

[0052] The present invention provides a mahjong machine with a tile-sorting function, which has a table assembly including a base and a top plate. The top plate has several openable and closable tile-dispensing openings. A table mounting plate is installed on the base, and the table mounting plate has a mahjong tile actuation assembly, including a shuffling assembly, several sets of tile-carrying assemblies, several sets of tile-stacking assemblies, several sets of tile-feeding assemblies, and a control assembly, used to realize the shuffling and stacking functions of the mahjong tiles. A tile-sorting mechanism and a stop plate are also included. The tile-sorting mechanism is installed on the base and includes a robotic arm rotary track, a multi-stage telescopic arm installed on the robotic arm rotary track, and a tile-grabbing component. The shuffling assembly, the several sets of tile-carrying assemblies, the several sets of tile-stacking assemblies, the several sets of tile-feeding assemblies, and the tile-sorting mechanism are all electrically connected to the control assembly. At least one of the table mounting plate and the robotic arm rotary track can rotate. Installed on the table frame, the tile sorting mechanism is used to transfer mahjong tiles. Based on the central count, the mechanism picks up the corresponding tiles from the draw track and transfers them to the temporary stop board. A tile sorting camera captures images of the tiles on the temporary stop board, identifying their suits and numbers, and sends this information to the controller. The controller, according to preset sorting rules (such as sequential arrangement), controls the tile sorting mechanism to rearrange the tiles onto the sorting track. Once sorting is complete, the tile outlet opens, and the drive unit delivers the tiles from the sorting and draw tracks to the outlet for the player to retrieve. From shuffling and stacking to sorting, no manual intervention is required; it truly achieves one-button start and automatic completion. Visual recognition ensures accurate tile information and avoids errors. Players no longer need to bend over to pick up tiles or manually sort them, allowing them to focus more on the game itself and enhancing their entertainment experience.

[0107] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0108] The core of this invention is to provide a mahjong machine with a tile-arranging function, which can automatically arrange the tiles, allowing players to focus more on the game itself and enhancing the immersive entertainment experience.

[0109] Another core aspect of this invention is to provide a method of using a mahjong machine with the aforementioned tile arrangement function.

[0110] Please refer to Figure 2 To address the current shortcomings of mahjong machines lacking tile arrangement functionality, this application provides a mahjong machine with tile arrangement functionality, comprising the following components: a table assembly 1 including a base 12 and a top plate 11, the top plate 11 having several openable and closable tile outlets 111; a table mounting plate 121 mounted on the base 12, the table mounting plate 121 having a mahjong tile actuation assembly, a tile arrangement mechanism 6, and a stop plate 7; the tile arrangement mechanism 6 being mounted on the base 12, the tile arrangement mechanism 6 including a robotic arm rotary track 64, a multi-stage telescopic arm 61 mounted on the robotic arm rotary track 64, and a tile gripper 62; at least one of the table mounting plate 121 and the robotic arm rotary track 64 being rotatably mounted on the table assembly 1; and the tile arrangement mechanism 6 being used to transfer mahjong tiles.

[0111] In this embodiment, one or both of the table mounting plate 121 and the robotic arm rotary track 64 can be rotatably mounted on the base 12, thus offering multiple layout options that can be adjusted according to requirements.

[0112] The mahjong tile action assembly includes the following structure:

[0113] Shuffling assembly 2 includes a shuffling disc 202 and a shuffling drive component 201 for driving the shuffling disc 202 to rotate. Several sets of card transport assemblies 3 include a card transport drive component 301 and a card transport conveyor belt 302. Several sets of card stacking assemblies 4 include a receiving plate for receiving mahjong tiles transported by the card transport conveyor belt 302, a pushing plate for pushing the receiving plate to stack mahjong tiles, a card stacking drive component for controlling the lifting and lowering of the receiving plate, and a pushing drive component for controlling the movement of the pushing plate. Several sets of card delivery assemblies 5 are installed on the table mounting plate 121, including a card sorting track 512 and a card grabbing track 511 with the same path, and a drive component for moving mahjong tiles along the card sorting track 512 and the card grabbing track 511. The drive components and control components 8 include a controller, a card sorting camera 81, and a central disk 82. The central disk 82 is equipped with several control buttons and a display. The beginning and end of the card sorting track 512 and the card grabbing track 511 are respectively connected to the corresponding card outlet 111 and the card stacking component 4. The shuffling drive component 201, the card stacking drive component 45, the card transport drive component 301, the card sorting mechanism 6, the card sorting camera 81, and the central disk 82 are all electrically connected to the controller. The controller receives and identifies the suits of the mahjong tiles to control the card sorting mechanism 6 to transfer the mahjong tiles between the temporary stop plate 7 and the card sorting track 512 and the card grabbing track 511 according to a preset program.

[0114] It should be noted that the shuffling plate 202 in this embodiment of the invention has a conical structure and is rotatably mounted on the table assembly 1. The cards are dispersed by rotation. The shuffling plate 202 is a commonly used and mature technology. Therefore, the specific details will not be repeated. Please refer to the existing technology.

[0115] In addition, the central plate 82 has a lifting function to open or close the opening of the top plate so that the mahjong tiles can be placed into the shuffling plate for shuffling. The lifting function of the central plate 82 can be achieved by a rotary motor in conjunction with a horizontal hole. At this time, the central plate 82 has an inner rod and an outer rod that slide against each other. The movement of the inner rod is guided and limited by the outer rod. The horizontal hole is set in the inner rod, and the extension direction of the horizontal hole is perpendicular to the lifting direction of the central plate 82. Thus, the rotary motor is activated to drive the inner rod to move up and down relative to the outer rod, thereby realizing the opening or closing of the top plate opening.

[0116] In one specific embodiment, the center plate 82 can be directly fixed to the table body assembly. Specifically, the center plate 82 can be directly installed on the base 12, which helps to prevent the center plate from rotating. However, the center plate 82 can also be installed on the table body mounting plate 121, which can also rotate together. Preferably, it is fixedly installed on the base 12 to avoid the center plate 82 from rotating.

[0117] In addition, in this embodiment of the invention, the card sorting mechanism 6 can adopt a robotic arm structure. Through the cooperation of the robotic arm structure and the card sorting camera 81, the functions of precise card grabbing and sorting can be realized.

[0118] In addition, in this embodiment of the invention, there are four sets of card arrangement track 512 and four sets of card grabbing track 511, which are located in the four directions of the table body component 1. At the same time, there are also four sets of card transport component 3 and card stacking component 4, which correspond to the corresponding track positions.

[0119] In one specific embodiment, the tile sorting camera 81 is located below the temporary stop plate 7, which is made of transparent material. This improves the clarity of the mahjong tiles captured by the tile sorting camera 81, thereby enhancing the accuracy of suit recognition.

[0120] In a specific implementation of this invention, the table assembly 1 includes a base 12 and a top plate 11. The top plate 11 has several openable and closable card-dispensing openings 111. The table assembly 1 has a square overall structure, and the number of card-dispensing openings 111 is typically four, located in the four directions of the table assembly 1. The shuffling assembly 2 includes a shuffling disc 202 and a shuffling drive component 201 that drives the shuffling disc 202 to rotate. The shuffling disc 202 is used to randomly mix the mahjong tiles, achieving the traditional shuffling function. Several sets of card-carrying assemblies 3 include a card-carrying drive component 301 and a card-carrying conveyor belt 302, that is, the card-carrying conveyor belt 302 is used to transport the mahjong tiles on the shuffling disc 202 to the next assembly. Several sets of stacking components 4 include a receiving plate for receiving mahjong tiles conveyed by the tile conveyor belt 302, a pushing plate for pushing the receiving plate to stack mahjong tiles, a stacking drive for controlling the lifting and lowering of the receiving plate, and a pushing drive for controlling the movement of the pushing plate. The stacking components 4 are used to stack mahjong tiles in pairs and push them to the end of the grabbing track 511. Several sets of tile feeding components 5 are installed on the table mounting plate 121, including a tile sorting track 512 and a grabbing track 511 with the same path, and a drive for driving the mahjong tiles to move along the tile sorting track 512 and the grabbing track 511. The control component 8 includes a controller, a tile sorting camera 81, and a central plate 8. 2. The central disk 82 is equipped with several control buttons and a display. The ends of the card sorting track 512 and the card grabbing track 511 are connected to the corresponding card dispensing ports 111 and card stacking components 4, respectively. The shuffling drive 201, card stacking drive 45, card transport drive 301, card sorting mechanism 6, and card sorting camera 81 are all electrically connected to the controller along with the central disk 82. The card sorting camera 81 is used to photograph and identify the mahjong tiles located on the temporary stop plate 7. The card sorting mechanism 6 is used to realize the transfer of mahjong tiles between the temporary stop plate 7 and the card sorting track 512 and card grabbing track 511 according to a preset program. The card sorting mechanism 6 grabs the corresponding mahjong tile from the card grabbing track 511 according to the number on the central disk 82. The cards are then transferred to the temporary stop plate 7. The card sorting camera 81 captures the cards on the temporary stop plate 7, identifies the suit and number, and feeds the information back to the controller. The controller, according to the preset card sorting rules (such as arranging in order), controls the card sorting mechanism 6 to rearrange the cards onto the card sorting track 512. After the card sorting is completed, the card outlet 111 opens, and the drive unit sends the cards on the card sorting track 512 and the card grabbing track 511 to the card outlet 111 for the player to take. From shuffling and stacking to sorting, no manual intervention is required, truly achieving one-click start and automatic completion. Visual recognition ensures accurate card information and avoids confusion. Players do not need to manually sort the cards and can focus more on the game itself, enhancing the entertainment experience.

[0121] Please refer to Figure 22In some embodiments, the table assembly 1 further includes several sets of card-dispensing opening and closing mechanisms 13, which are installed on the base 12. Each card-dispensing opening and closing mechanism 13 includes a card-dispensing cover plate 131 and a card-dispensing drive component 132. The card-dispensing drive component 132 is electrically connected to the controller and is used to control the movement of the card-dispensing cover plate 131 to control the opening and closing of the card-dispensing port 111. The card-dispensing cover plate 131 is located on the side of the card-dispensing port 111 away from the direction of playing mahjong tiles, and is hinged to the top plate via a pivot. 11. The card outlet drive component 132 is used to control the rotation of the card outlet cover plate 131. Specifically, the card outlet opening and closing mechanism also includes a card outlet connecting rod 133. One end of the card outlet connecting rod 133 is fixedly connected to the rotating shaft, and the other end of the card outlet connecting rod 133 is provided with a drive groove 134. The card outlet drive component 132 is a motor. The output end of the motor is provided with a rocker arm 139. The end of the rocker arm 139 away from the motor output end is fixed with a drive pin 135 that slides in cooperation with the drive groove 134.

[0122] That is, the card dispensing opening and closing mechanism 13 is installed on the base 12 and corresponds to each card dispensing opening 111. It includes a cover plate 131 that is hinged to the top plate 11 via a rotating shaft and can rotate around the rotating shaft. The card dispensing opening drive component 132 is a motor that is electrically connected to the controller. A card dispensing opening connecting rod 133 is fixedly connected to the rotating shaft. The other end of the card dispensing opening connecting rod 133 is provided with an elongated oval drive groove 134. A rocker arm 139 is installed at the output end of the motor. A drive pin 135 is fixed at the end of the rocker arm 139 away from the motor output end. The drive pin 135 slides in the drive groove 134. Therefore, when the controller needs to open the card dispensing opening 111, the motor is started. The motor output end drives the rocker arm 139 to rotate. The drive pin 135 on the rocker arm 139 rotates at the card dispensing opening. The lever 133 slides within the drive groove 134, pushing the connecting rod to swing around the pivot, thereby causing the pivot fixed to the connecting rod to rotate, causing the card outlet cover 131 to flip outward and open. When closing, the motor reverses to control the cover 131 to reset. The cooperation between the drive groove 134 and the drive pin 135 allows for a certain degree of motion error, ensuring smooth operation. There is no need for manual opening and closing of the card outlet 111, improving the degree of automation. The linkage mechanism converts the rotational motion of the motor into the smooth flipping of the cover 131 without impact, which helps to improve the user experience of the mahjong machine. Furthermore, the card outlet cover 131 is located on the side of the card outlet 111 away from the direction of the mahjong card being played, which can avoid interference when the mahjong card is pushed out, improving the stability of the mahjong machine during operation.

[0123] Please refer to Figure 4 In some embodiments, a circular table mounting plate 121 is rotatably mounted on the base 12, and a table driving component 122 for driving the table mounting plate 121 to rotate is mounted on the base 12. The shuffling component 2, several sets of card transport components 3, several sets of card stacking components 4, several sets of card delivery components 5, the control component 8 and the temporary stop plate 7 are all mounted on the table mounting plate 121, and the table driving component 122 is electrically connected to the controller.

[0124] In one specific embodiment, the card-dispensing port connecting rod 133 is arranged perpendicularly to the rotating shaft. That is, the bottom of the top plate 11 is provided with a fixing ring, and a bearing is provided inside the fixing ring. The rotating shaft is rotatably mounted on the bearing, which helps to reduce friction when the rotating shaft rotates, reduce noise, and improve the user experience of the mahjong machine. At the same time, the end of the rotating shaft near the cover plate 131 is fixedly connected to the cover plate 131, while the end of the rotating shaft away from the cover plate 131 extends out of the fixing ring. The end of the rotating shaft of the card-dispensing port connecting rod 133 extending out of the fixing ring is fixedly connected and arranged vertically.

[0125] In this embodiment, the drive groove 134 is formed by a strip-shaped annular structure, and its length direction is arranged perpendicular to the axis of the rotating shaft.

[0126] In this embodiment, two support plates 138 are also included. Both support plates 138 are installed on the table body assembly 1. The card dispensing drive component 132 is fixed to one of the support plates 138, while the other support plate 138 is provided with a sliding groove 137. A stabilizing rod 136 is slidably installed in the sliding groove 137. The end of the stabilizing rod 136 extending out of the sliding groove 137 is fixedly connected to the drive groove 134. The sliding groove 137 is an arc-shaped structure with the axis of the rotating shaft as the central axis, which can stabilize the rotation of the drive groove 134 and improve the stability of the cover plate 131 during the opening and closing process.

[0127] In this embodiment, please refer to Figure 25 The layout adopts a mechanical arm rotary track 64 fixed to the base 12. Specifically, the card sorting mechanism 6 includes a mechanical arm rotary track 64, a multi-stage telescopic arm 61, and a card grabbing component 62.

[0128] The robotic arm's rotary track 64 is fixedly mounted on the table assembly 1;

[0129] The root of the multi-stage telescopic arm 61 is slidably mounted to the robotic arm rotary track 64, and the multi-stage telescopic arm 61 includes a revolution drive assembly for driving the multi-stage telescopic arm 61 to move around the robotic arm rotary track 64.

[0130] The card grabber 62 is located at the free end of the multi-stage telescopic arm 61.

[0131] That is, the robotic arm rotary track 64 forms a preset track and is fixedly connected to the base 12. The revolution drive component drives the multi-stage telescopic arm 61 and the card grabber 62 to move along the guide path of the robotic arm rotary track 64, so as to realize the spatial position adjustment of the card grabber 62 and the base 12.

[0132] In some cases, four sets of multi-stage telescopic arms 61 and card-grabbing components 62 are slidably installed within the rotary track 64 of the robotic arm. The four sets of multi-stage telescopic arms 61 and card-grabbing components 62 can be independently controlled to revolve. Through algorithm control, such as calculating the step amount of the revolution drive component corresponding to each multi-stage telescopic arm 61, the position of the multi-stage telescopic arm 61 and the distance between it and the connected multi-stage telescopic arms 61 are obtained to avoid motion interference of multiple multi-stage telescopic arms 61.

[0133] In some cases, a position sensor is installed inside the base 12 corresponding to each player's position to sense the position of the multi-stage telescopic arm 61 and realize closed-loop control of the position of the multi-stage telescopic arm 61.

[0134] The revolution drive component is usually driven by a motor. A gear is set at the output shaft end of the motor, which meshes with a gear ring arranged coaxially with the rotary track 64 of the robotic arm, thereby realizing the drive of the multi-stage telescopic arm 61.

[0135] In this embodiment, a layout is adopted in which the robotic arm rotary track 64 is rotatably mounted on the base 12. Specifically, the card sorting mechanism 6 includes the robotic arm rotary track 64, the multi-stage telescopic arm 61, and the card gripper 62.

[0136] The robotic arm rotary track 64 is rotatably mounted on the table assembly 1. The robotic arm rotary track 64 includes a revolution drive assembly for driving the robotic arm rotary track 64 to rotate relative to the table assembly 1.

[0137] The root of the multi-stage telescopic arm 61 is fixedly connected to the robotic arm rotary track 64;

[0138] The card grabber 62 is located at the free end of the multi-stage telescopic arm 61.

[0139] The robotic arm rotary track 64 forms a preset track and is rotatably connected to the base 12. The robotic arm rotary track 64 is driven to rotate relative to the base 12 by the revolution drive component.

[0140] The multi-stage telescopic arm 61 and the card grabbing component 62 are fixedly connected to the robotic arm rotary track 64, and thus rotate synchronously with the robotic arm rotary track 64, thereby realizing the spatial position adjustment of the card grabbing component 62 and the base 12.

[0141] In this embodiment, the table mounting plate 121 is rotatably mounted on the base 12. Specifically, the base 12 has a recessed groove, and the table mounting plate 121 is circular and is located in the groove. A drive shaft is rotatably mounted in the groove and is arranged coaxially with the table mounting plate 121. The table drive component 122 is used to control the rotation of the drive shaft. The shuffling component 2, several sets of card transport components 3, several sets of card stacking components 4, several sets of card delivery components 5, the control component 8, and the temporary stop plate 7 are all mounted on the table mounting plate 121 and rotate together with the table mounting plate 121. The rotating table mounting plate 121 and the card sorting mechanism 6 fixed on the base 12 cooperate with each other to realize the precise operation of sorting and grabbing cards.

[0142] In one specific embodiment, the table drive 122 may be a motor in conjunction with a reducer, driven by gears or a synchronous belt.

[0143] In one specific embodiment, the rotating table mounting plate 121 can reduce the number of parts in the mahjong machine. Specifically, only one set of card arrangement mechanism 6 is needed. During the card drawing and arrangement stage, it rotates to the working range of the robotic arm, and during the card playing stage, it rotates to the direction of the corresponding player, reducing the number of parts and greatly reducing costs.

[0144] In this embodiment, the table mounting plate 121 and the robotic arm rotary track 64 are both rotatably mounted on the base 12. Specifically, the card sorting mechanism 6 includes the robotic arm rotary track 64, the multi-stage telescopic arm 61, and the card grabbing component 62.

[0145] The robotic arm rotary track 64 is rotatably mounted on the table assembly 1. The robotic arm rotary track 64 includes a revolution drive assembly for driving the robotic arm rotary track 64 to rotate relative to the table assembly 1.

[0146] The card grabber 62 is located at the free end of the multi-stage telescopic arm 61.

[0147] The robotic arm rotary track 64 forms a preset track and is rotatably connected to the base 12. The robotic arm rotary track 64 is driven to rotate relative to the base 12 by the revolution drive component.

[0148] The multi-stage telescopic arm 61 and the card grabbing component 62 are fixedly connected to the robotic arm rotary track 64, and thus rotate synchronously with the robotic arm rotary track 64 to realize the spatial position adjustment of the card grabbing component 62 and the base 12.

[0149] Meanwhile, the base 12 has a recessed groove, and the table mounting plate 121 is circular and is set in the groove. A drive shaft is rotatably installed in the groove. The drive shaft is arranged coaxially with the table mounting plate 121. The table drive component 122 is used to control the rotation of the drive shaft. The shuffling component 2, several sets of card transport components 3, several sets of card stacking components 4, several sets of card delivery components 5, control component 8 and temporary stop plate 7 are all installed on the table mounting plate 121 and rotate together with the table mounting plate 121. The rotating table mounting plate 121 and the card sorting mechanism 6 fixed on the base 12 cooperate with each other to realize the precise operation of sorting and grabbing cards.

[0150] In one specific embodiment, the table assembly 1 further includes a locator, which is installed on the base 12 and the table mounting plate 121. Its function is to return to its original position after the table mounting plate 121 rotates one revolution, ensuring that the position of the table mounting plate 121 is fixed before each rotation, and to place the mahjong tiles picked up by the robotic arm at each position onto the corresponding temporary stop plate after returning to its original position.

[0151] In another specific embodiment, the card sorting mechanism further includes a locator. When the robotic arm rotary track 64 is rotatably mounted on the base 12, the locator is mounted on the robotic arm rotary track 64 or the base 12. Its function is to return to its original position after the robotic arm rotary track 64 has rotated one revolution, ensuring that the position of the robotic arm rotary track 64 is fixed before each rotation, and after returning to its original position, to place the mahjong tiles grabbed by the robotic arm at each position onto the corresponding temporary stop plate.

[0152] In another specific embodiment, the tile sorting mechanism further includes at least one locator, which is installed on the tile sorting mechanism 6 or the base 12. Its function is to return to its original position after the tile sorting mechanism 6 rotates one revolution, ensuring that the position of the tile sorting mechanism 6 is fixed before each rotation, and to place the mahjong tiles grabbed by the robotic arm at each position onto the corresponding temporary stop plate after returning to its original position.

[0153] Please refer to Figure 2 In some embodiments, the shuffling disc 202 is rotatably mounted on the table mounting plate 121. The card transport assembly 3 also includes a card transport driven wheel 304 and a card transport driving wheel 303. The card transport conveyor belt 302 is wound around the card transport driven wheel 304 and the card transport driving wheel 303. The card transport driving wheel 303 is provided with several card-attracting magnets for attracting mahjong tiles on the shuffling disc 202 to the card transport conveyor belt 302. The card transport drive component 301 is used to control the rotation of the card transport driving wheel 303 to transport the attracted mahjong tiles to the receiving plate.

[0154] That is, the shuffling disc 202 is rotatably mounted on the table mounting plate 121. The driven wheel 304 and the driving wheel 303 are connected by a conveyor belt 302, forming a circular conveying path. Multiple magnets are mounted on the driving wheel 303, evenly distributed around its circumference. Ferromagnetic materials (such as iron sheets) are embedded within the mahjong tiles. When the driving wheel rotates, the magnets approach the edge of the shuffling disc 202, attracting the mahjong tiles to the conveyor belt 302. The driving unit 301 controls the driving wheel 303 to rotate, driving the conveyor belt... The conveyor belt moves to transport the mahjong tiles to the receiving plate of the stacking assembly 4. As the shuffling disc 202 rotates, the mahjong tiles continuously pass near the drive wheel. The magnets attract and fix the tiles to the conveyor belt. The rotating conveyor belt carries the tiles away from the shuffling disc 202 and onto the receiving plate. When the tiles reach the receiving plate, they automatically fall onto it due to the change in the direction of the conveyor belt. The magnetic attraction method involves no mechanical contact and will not damage the surface of the mahjong tiles. The magnets are fixed in position, and the tiles are consistently positioned on the conveyor belt, facilitating subsequent processing and providing precise positioning.

[0155] For specific details, please refer to Figure 19 The stacking component 4 includes a stacking mounting frame 41 mounted on the table body component 1, a receiving plate 42 slidably mounted on the stacking mounting frame 41 for receiving mahjong tiles conveyed by the tile conveyor belt, a pushing plate 43 slidably mounted on the stacking mounting frame 41 for pushing the mahjong tiles stacked on the receiving plate 42 to the tile delivery component 5, a stacking drive mechanism 44 for simultaneously controlling the lifting and lowering of the receiving plate 42 and the movement of the pushing plate 43, and a stacking drive component 45 mounted on the stacking mounting frame 41 for controlling the movement of the stacking drive mechanism 44 to achieve simultaneous control of the lifting and lowering of the receiving plate 42 and the movement of the pushing plate 43.

[0156] It should be noted that, in this embodiment of the invention, the table assembly 1, the card feeding assembly 5, and the card transport assembly 3 are the basic components of the mahjong machine. The table assembly 1 provides the installation base, the card transport assembly 3 transports the shuffled mahjong tiles from the shuffling plate to the stacking assembly 4, and the card feeding assembly 5 transports the stacked tiles to the card dispensing port.

[0157] In some embodiments, the stacking drive 45 may be a cylinder or a hydraulic cylinder, and the stacking and pushing of mahjong tiles can be achieved by controlling the docking plate 42 and the pushing plate 43 respectively.

[0158] In a specific implementation of the present invention, the stacking component 4 includes a stacking mounting frame 41 installed on the table body component 1. The stacking mounting frame 41 serves as the supporting skeleton of the entire stacking component 4, bearing movable parts. A receiving plate 42 is slidably installed on the stacking mounting frame 41 to receive mahjong tiles conveyed by the tile conveyor belt. The receiving plate 42 can be raised and lowered to stack different numbers of mahjong tiles. A pushing plate 43 is slidably installed on the stacking mounting frame 41 to push the mahjong tiles stacked on the receiving plate 42 to the tile conveying component 3. The pushing plate 43 can move horizontally to achieve the lateral transfer of tiles to the delivery component 5. The stacking drive mechanism 44 is used to simultaneously control the raising and lowering action of the receiving plate 42 and the movement of the pushing plate 43. Furthermore, a stacking drive component 45 is installed on the stacking mounting frame 41 and is used to control the movement of the stacking drive mechanism 44 to simultaneously control the raising and lowering action of the receiving plate 42 and the movement of the pushing plate 43.

[0159] That is, the tile conveying component 3 transports the mahjong tiles one by one to the receiving plate 42. After leaving the tile conveying component 3, the mahjong tiles fall onto the receiving plate 42 by gravity. The receiving plate 42 gradually descends under the control of the stacking drive mechanism 44, so that the subsequent tiles can be smoothly stacked on top of the previous tile, thus realizing the stacking of mahjong tiles. When the tiles on the receiving plate 42 are stacked to a predetermined number (such as the number of tiles in a stack, for example, two tiles stacked as a stack), the stacking drive mechanism 44 drives the tile pushing plate 43 to move horizontally, moving the entire stack of tiles from the receiving plate 42. The tile plate 42 is pushed to the entrance of the tile feeding component 5, then the tile pushing plate 43 is reset, and the tile receiving plate 42 rises to the initial position to wait for the next batch of tiles to arrive. This cycle is repeated to realize the automatic stacking and pushing of mahjong tiles. A single drive unit controls the lifting and horizontal movement at the same time, reducing the number of drive units, lowering costs, and saving internal space in the mahjong machine. This facilitates the overall layout of the machine. The tile receiving and pushing actions are coordinated by the same drive mechanism, with precise timing, avoiding the risk of tile jamming, and improving the user experience of the mahjong machine.

[0160] Please refer to Figure 19 In some embodiments, the card stacking drive 45 is a motor mounted on the card stacking mounting frame 41. The card stacking drive mechanism 44 includes a card receiving drive 441, a card pushing drive 442, and a drive pin 443. The card receiving drive 441 is a strip-shaped groove perpendicular to the moving direction of the card receiving plate 42. The card receiving drive 441 is fixedly connected to the card receiving plate 42 and slidably mounted on the card stacking mounting frame 41 along the moving direction of the card receiving plate 42. The card pushing drive 442 is a combination of arc and strip structure. The card pushing drive 442 is fixedly connected to the card pushing plate 43 and slidably mounted on the card stacking mounting frame 41 along the moving direction of the card pushing plate 43. The drive pin 443 passes through the card receiving drive 441 and the card pushing drive 442 and slides in cooperation with the card receiving drive 441 and the card pushing drive 442. The card stacking drive 45 is used to control the drive pin 443 to move along a preset trajectory to control the movement of the card receiving drive 441 and the card pushing drive 442.

[0161] In the above embodiments, the card-pushing drive component 442 is a combination of arc-shaped and strip-shaped structures, specifically as follows: Figure 6 The structure shown has an upper part that is a quarter-circle arc shape and a lower part that is a strip shape, and the two structures are smoothly connected so that the pin can move smoothly within the push drive 442.

[0162] Optionally, in some embodiments, the card receiving drive 441 and the card pushing drive 442 may adopt a structure such as a strip-shaped groove or a sliding hole.

[0163] And please continue to refer to Figure 19 In some embodiments, the card stacking drive mechanism 44 further includes a card stacking rocker arm 444, which is arranged perpendicularly to the drive pin 443. One end of the card stacking rocker arm 444 is fixedly connected to the drive pin 443, and the other end is fixedly connected to the output end of the card stacking drive component 45, so that the drive pin 443 can move in a circular motion around the axis of the output end of the card stacking drive component 45.

[0164] That is, one end of the stacking rocker 444 is fixedly connected to the drive pin 443, and the other end is fixedly connected to the output end of the motor. The function of the stacking rocker 444 is to convert the rotational motion of the motor into the circular motion of the drive pin 443. The receiving drive component 441 is a strip groove (i.e., a horizontal long groove) perpendicular to the moving direction (lifting direction) of the receiving plate 42. It is fixedly connected to the receiving plate 42 and slidably installed on the stacking mounting frame 41 along the moving direction (lifting direction) of the receiving plate 42. That is, the up and down movement of the receiving drive component 441 can drive the receiving plate 42 to move up and down. The pushing drive component 442 is a combination of arc and strip structure. It is fixedly connected to the pushing plate 43 and slidably installed on the stacking mounting frame 41 along the moving direction (horizontal direction) of the pushing plate 43. The design of the combination of arc groove and strip groove allows the drive pin 443 to generate a horizontal pushing force when it slides to its limit position, thereby pushing the pushing plate 43 to move horizontally.

[0165] like Figure 20As shown, the card-pushing drive component 442 is a combination of a quarter-circular arc structure and a strip structure. In the initial position, the drive pin 443 is located at the extreme position at the top of the card-pushing drive component 442, and at the same time, it is located in the middle position of the card-pushing drive component 442. Therefore, when the motor starts, it drives the card-stacking rocker arm 444 to rotate, and the drive pin 443 makes a circular motion around the axis of the motor output end. When the drive pin 443 slides inside the card-receiving drive component 441, due to the horizontal component of its circular motion, it will generate a vertical force on the card-receiving drive component 441, pushing the card-receiving drive component 441 (and the card-receiving plate 42) to move up and down, thereby controlling the up and down movement of the card-receiving plate 42. At this time, the arc shape of the card-pushing drive component 442 can prevent the drive pin 443 from moving the card-pushing plate 43 during the movement. Shaft 443 continues to descend, causing the receiving plate 42 to continuously descend to achieve the stacking effect of mahjong tiles. At this time, drive pin 443 enters the strip position of pusher 442, so pusher 43 is controlled to move. When drive pin 443 moves to the bottom, that is, the lower limit position of pusher 442, drive pin 443 continues to rotate, which will drive pusher 442 to move, thereby causing pusher 43 to move horizontally and push the tiles. After the pusher action is completed, the motor reverses and returns to the initial position. By cleverly designing the contours of the arc groove and strip groove, the lifting and lowering of receiving plate 42 and the horizontal movement of pusher 43 can be alternated according to a preset timing, reducing the use of drive components, while precisely controlling the start time and stroke of pusher action.

[0166] Please refer to Figure 19 In some embodiments, the stacking drive mechanism 44 further includes at least one receiving guide rod 446, which is mounted on the stacking mounting frame 41 and arranged along the moving direction of the receiving drive member 441. The receiving drive member 441 and the receiving guide rod 446 are slidably engaged to ensure that the receiving drive member 441 does not wobble during the lifting and lowering process. When the drive pin 443 pushes the receiving drive member 441 to lift and lower, the receiving guide rod 446 restricts its movement direction to prevent tilting or jamming caused by uneven force.

[0167] In other embodiments, the movement and guiding function of the pusher 442 can be achieved by setting a guide rail on the stacking plate mounting bracket 41 and sliding the receiving plate drive 441 with the guide rail.

[0168] Please refer to Figure 21In some embodiments, the card stacking drive mechanism 44 further includes at least one card pusher guide rod 445, which is mounted on the card stacking mounting frame 41 and arranged along the moving direction of the card pusher drive member 442. The card pusher drive member 442 and the card pusher guide rod 445 are slidably engaged to ensure that the card pusher drive member 442 remains straight during horizontal movement. The card pusher guide rod 445 ensures the straightness of the card pusher drive member 442 during horizontal movement, so that the card pusher plate 43 can accurately push the card to the target position.

[0169] In other embodiments, the movement of the card pusher 442 can be guided by providing a guide rail on the card stacking mounting bracket 41 and slidingly engaging the card pusher 442 with the guide rail.

[0170] In one specific embodiment, a counter is also installed on the stacking tile mounting frame 41. The counter has two functions: first, to count the total number of mahjong tiles in the transport component. When the total number reaches a set value, the conveyor belt stops transporting mahjong tiles, the conveyor belt of the transport component reverses, and the mahjong tiles left on the conveyor belt are returned to the shuffling tray for use in other locations; second, after counting two stacked tiles, the pusher plate 43 is driven to push the mahjong tiles into the receiving plate, and at this time the conveyor belt of the transport component is in a stopped state.

[0171] In one specific embodiment, a baffle is also slidably installed on the stacking tile mounting frame 41. The baffle is located between the receiving tile plate 42 and the tile conveying component 3. Its lifting and lowering are controlled by an electric cylinder. A counter is provided between the receiving tile plate 42 and the tile conveying component 3 or on the receiving tile plate 42. When the counter on the receiving tile plate 42 detects that the number of mahjong tiles on it meets the preset number, the electric cylinder controls the baffle to rise, forming a block between the receiving tile plate 42 and the tile conveying component 3 to prevent the mahjong tiles from moving. After the pushing tile plate 43 pushes the stacked mahjong tiles to the preset position and the initial position, the electric cylinder controls the baffle to fall, so that the mahjong tiles can be moved to the receiving tile plate 42. This can prevent the mahjong tiles from being concentrated on the receiving tile plate 42 and ensure the normal operation of the mahjong machine.

[0172] Please refer to Figure 17 In some embodiments, the stacking card assembly 4 further includes a stacking card support frame 447, which is mounted on the stacking card mounting frame 41. The stacking card support frame 447 has a stacking card through hole 4471. The area of ​​the stacking card through hole 4471 is larger than the area of ​​the receiving plate 42 and smaller than the area of ​​the mahjong tiles, so that the receiving plate 42 can move freely within the stacking card through hole 4471. The pushing plate 43 is located above the stacking card support frame 447, that is, the receiving plate 42 can move freely up and down within the through hole, while the mahjong tiles are supported by the edge of the through hole and will not fall out as the receiving plate 42 descends. The pushing plate 43 is located above the stacking card support frame 447 and is used to push away the tiles stacked on the support frame.

[0173] In the initial state, the receiving plate 42 rises to a height higher than the stacking support frame 447, with its upper surface higher than the upper surface of the support frame. The tile conveying component 3 delivers the mahjong tiles to the receiving plate 42. Under the control of the drive mechanism, the receiving plate 42 gradually descends. When the upper surface of the receiving plate 42 is at the same height as the upper surface of the stacking support frame 447, the stacking of two tiles is completed. At this time, the drive pin 443 is located at the halfway point of the push drive component 442. The receiving plate 42 continues to descend below the through hole and finally moves to the bottom. At this time, the drive pin 44... 3 is located at the lower limit position of the pusher 442. At this time, the mahjong tiles are held by the edge of the through hole of the support frame and remain on the support frame. Therefore, the continued rotation of the drive pin 443 can realize the horizontal movement of the pusher plate 43, pushing the entire stack of tiles from the support frame to the delivery component 5. The motor reverses to return the component to the initial position. Therefore, the through hole design of the support frame in this structure ensures that the mahjong tiles are reliably supported during the stacking process and will not fall. After the receiving plate 42 is separated from the mahjong tiles, it can be raised and lowered freely without affecting the pusher plate 43 pushing the stacked mahjong tiles.

[0174] Please refer to Figure 17 In some embodiments, the stacking support frame 447 has an inclined surface on the side near the card delivery component 3 and a stacking support plate 4472 in contact with the card delivery track 51. The card delivery track 51 is placed above the stacking support plate 4472, and the rear end of the stacking support plate 4472 has a stepped surface. The stepped surface is used to limit the card delivery track 51 and eliminate the height difference between the stacking support plate 4472 and the card delivery track 51. When the pusher plate 43 pushes the entire stack of cards from the support frame to the card delivery component 5, the mahjong cards directly enter the card delivery track 51, avoiding jamming or tipping caused by the height difference.

[0175] In one embodiment, the card feeding assembly includes a card feeding track, a card arranging drive mechanism, and a card grabbing drive mechanism. The two ends of the card feeding track are connected to the card dispensing port and the card stacking assembly, respectively. A card feeding baffle is provided in the middle of the card feeding track along the track direction. The card feeding baffle divides the card feeding track into independent card arranging tracks and card grabbing tracks. The card arranging drive mechanism is used to push the mahjong tiles along the card arranging track and from the card dispensing port to the top plate surface. The card grabbing drive mechanism is used to push the mahjong tiles along the card grabbing track and from the card dispensing port to the top plate surface. The top plate is part of the mahjong machine table and has a card dispensing port on it for outputting the arranged mahjong tiles to the table for players to grab. The card stacking assembly is located below the top plate and is used to stack the shuffled mahjong tiles neatly and transport them to the card feeding track entrance. Therefore, the card stacking support plate 4472 can enable the mahjong tiles to move smoothly to the card feeding track, while ensuring the stability of the card feeding track and reducing the shaking of the card feeding track during use.

[0176] Please refer to Figure 18In some embodiments, the receiving plate 42 is provided with a stacking magnet 421, which is installed on the receiving plate 42. It is usually a permanent magnet. The mahjong tiles are embedded with ferromagnetic material (such as iron sheets). When the tiles fall on the receiving plate 42, the attraction of the magnet makes the tiles stick to the receiving plate 42 and stay steadily on the receiving plate 42, preventing the tiles from sliding or shifting during the stacking process.

[0177] Please refer to Figure 17 In some embodiments, the stacking component 4 also includes a stacking first camera 46, which is installed on the stacking mounting bracket 41 and is used to monitor the mahjong tiles at the transport component 3. When the mahjong tiles on this side meet the preset number value, if the first camera 46 detects that there are still mahjong tiles on the transport component 3 that have not been sent to the receiving plate, the transport component 3 rotates in the opposite direction to return the excess mahjong tiles to the shuffling component 2 for use in other directions.

[0178] The card stacking component 4 also includes a second card stacking camera 47, which is installed on the card stacking mounting frame 41 and is used to monitor the card delivery component 5. It is used to monitor the card delivery process, and can detect whether there are cards on the card delivery conveyor belt, whether the position of the cards is normal, etc. At the same time, it can also monitor whether the player is cheating during the card arrangement process.

[0179] In one embodiment, the second camera 47 can provide visual support for the tile arrangement mechanism 6 to transfer mahjong tiles between the temporary stop plate 7 and the tile delivery component 5. That is, the controller can determine the tile grabbing position and tile placement position of the tile arrangement mechanism 6 by receiving the image from the second camera 47, which is conducive to further improving the neatness and regularity of the mahjong tiles in the tile delivery component 5. The position of the second camera 47 can be adjusted, for example, it can be set directly above the position between the temporary stop plate 7 and the tile delivery component 5.

[0180] Please refer to Figure 13 In some embodiments, the card sorting mechanism 6 includes a multi-stage telescopic arm 61, a card grabbing component 62, and a rotating lifting base 63. The card grabbing component 62 is installed at the output end of the multi-stage telescopic arm 61. The rotating lifting base 63 includes a lifting drive component 631 and a rotating drive component 632. The base 12 is provided with a rotating lifting base mounting groove, and the rotating lifting base 63 is installed in the rotating lifting base mounting groove. The card grabbing component 62 is used to pick up and put down mahjong tiles. The lifting drive component 631 and the rotating drive component 632 are both electrically connected to the controller, and the mahjong tiles are transferred between the temporary stop plate 7 and the track through the lifting drive component 631 and the rotating drive component 632.

[0181] That is, the multi-stage telescopic arm 61 is installed at the output end of the rotating lifting base 63, and can extend and retract in the horizontal direction to achieve grasping at both near and far distances. Its end is equipped with a card-grabbing component 62 for picking up and putting down mahjong tiles. The rotating lifting base 63 includes a lifting drive component 631 and a rotating drive component 632, which are installed in the rotating lifting base mounting slot on the base 12. Therefore, the lifting drive component 631 controls the lifting of the entire robot arm, the rotating drive component 632 controls the horizontal rotation of the robot arm, and the rotating drive component 632 controls the overall orientation of the multi-stage telescopic arm 61. The lifting drive component 631 adjusts the height of the robot arm. The multi-stage telescopic arm 61 adjusts the position of the card-grabbing component 62 by extending and retracting, so that the card-grabbing component 62 can reach different positions such as the card-grabbing track 511, the temporary stop plate 7, and the card-sorting track 512 to complete the transfer of mahjong tiles. The multi-degree-of-freedom combination allows the robot arm to cover the entire internal area of ​​the table assembly 1. The height and angle can be adjusted as needed to avoid obstacles. When the telescopic arm is retracted, it occupies little space and does not affect other components.

[0182] Please refer to Figure 16 In some embodiments, the rotating lifting base 63 further includes a lifting mounting plate 634, a rotating mounting plate 635, and a support column 636. The lifting mounting plate 634 is slidably installed inside the rotating lifting base 63. The lifting drive component 631 is used to control the sliding of the lifting mounting plate 634. The rotating mounting plate 635 is rotatably installed on the lifting mounting plate 634. The support column 636 is fixed to the rotating mounting plate 635. The end of the support column 636 extending out of the rotating lifting base 63 is connected to the multi-stage telescopic arm 61. The rotating lifting base 63 also includes at least one lifting limit rod 637 and a lifting screw 633. The lifting limit rod 637 is installed inside the rotating lifting base 63. The lifting mounting plate 634 and the lifting limit rod 637 are slidably engaged. The lifting drive component 631 is a motor and is fixed inside the rotating lifting base 63. The lifting screw 633 is installed at the output end of the lifting drive component 631 and is threadedly engaged with the lifting mounting plate 634. The support column 636 is a hollow structure and is sleeved on the lifting screw 633.

[0183] That is, the rotating and lifting base 63 includes a housing, which is fixed to the base 12 of the table assembly 1. The housing has a slide rail or guide inside to guide the lifting mounting plate 634. The lifting mounting plate 634 is slidably installed inside the housing. The lifting drive component 631 is a motor, fixed inside the rotating and lifting base 63. A lifting screw 633 is installed at the motor output end, and the lifting screw 633 is threaded into the lifting mounting plate 634. When the motor rotates, it drives the lifting mounting plate 634 to rise and fall. The support column 636 is fixed to the rotating mounting plate 635, extends outside the rotating and lifting base 63, and its top end is connected to the multi-stage telescopic arm 61. 36 is a hollow structure, sleeved on the outside of the lifting screw 633. It transmits rotational motion and provides space for the screw, while ensuring the concentricity of the lifting screw 633 and the support column 636. This is beneficial for calculating the rotation angle of the multi-stage telescopic arm 61. The rotating mounting plate 635 is rotatably mounted on the lifting mounting plate 634. Therefore, when the lifting motor rotates, it drives the lifting mounting plate 634 to move up and down along the limit rod through the screw, thereby driving the entire rotating part to rise and fall. The rotating motor drives the rotating mounting plate 635 to rotate, which drives the multi-stage telescopic arm 61 to rotate through the support column 636. The lifting and rotational motions are independently controlled and do not interfere with each other. They can operate simultaneously or separately, providing high flexibility.

[0184] In one specific embodiment, the lifting limit rod 637 is installed inside the housing and arranged parallel to the lifting screw 633. At least two lifting limit rods 637 may be used and evenly distributed around the axis of the lifting screw 633.

[0185] In one specific embodiment, a rotary drive component 632 is also provided. The rotary drive component 632 is a motor and is fixed on the lifting mounting plate 634. A bearing is installed on the lifting mounting plate 634, and a rotary mounting plate 635 is installed on the upper part of the bearing. The support column 636 is fixedly connected to the rotary mounting plate 635. Therefore, the rotary drive component 632 can control the rotation of the multi-stage telescopic arm 61 by driving the rotation of the rotary mounting plate 635 or the support column 636.

[0186] In one specific embodiment, the rotary drive 632 can be connected to the rotary mounting plate 635 via gears or belts to achieve rotation control of the rotary mounting plate 635.

[0187] Please refer to Figure 15In some embodiments, the multi-stage telescopic arm 61 includes a primary telescopic arm 611 and a secondary telescopic arm 622. The primary telescopic arm 611 includes a primary telescopic frame 6110, a primary slider 6111 slidably installed inside the primary telescopic frame 6110, and a primary drive member 6112 that drives the primary slider 6111 to slide along the primary telescopic frame 6110. The secondary telescopic arm 622 includes a secondary telescopic frame 6220, a secondary slider 6224 slidably installed inside the secondary telescopic frame 6220, and a secondary drive member 6221 that drives the secondary slider 6224 to slide along the secondary telescopic frame 6220. The primary telescopic frame 6110 is connected to the output end of the robot's rotary motor, the secondary telescopic frame 6220 is connected to the primary slider 6111, and the card-grabbing component 62 is connected to the secondary slider 6224.

[0188] That is, the primary slider 6111 is slidably installed inside the primary telescopic frame 6110, and the primary drive component 6112 drives the primary slider 6111 to slide along the primary telescopic frame 6110. The secondary slider 6224 is slidably installed inside the secondary telescopic frame 6220, and the secondary drive component 6221 drives the secondary slider 6224 to slide. Therefore, the primary drive component 6112 drives the primary slider 6111 to move, which in turn moves the entire secondary telescopic arm 622 to achieve coarse positioning. The secondary drive component 6221 drives the secondary slider 6224 to move, which in turn moves the card gripper 62 to move further to achieve precise positioning. The two-stage telescopic system works in coordination to achieve a large range of strokes. At the same time, the overall length is relatively short when retracted. The two-stage telescopic system can achieve a large range of movement within a limited installation space.

[0189] In one specific embodiment, both the primary drive unit 6112 and the secondary drive unit 6221 can be driven by a cylinder or an electric cylinder.

[0190] In one specific embodiment, both the primary telescopic frame 6110 and the secondary telescopic frame 6220 are housing mechanisms, and a sliding hole extending along its length is provided above the primary telescopic frame 6110. The telescopic frame connecting rod is slidably installed in the sliding hole, and one end of the telescopic frame connecting rod is connected to the primary slider 6111, and the other end is connected to the secondary telescopic frame 6220.

[0191] Please refer to Figure 15 In some embodiments, the primary telescopic arm 611 further includes at least one primary lead screw 6113, which is rotatably mounted inside the primary telescopic frame 6110. The primary slider 6111 is threadedly engaged with the primary lead screw 6113. The primary drive unit 6112 is a motor and is mounted inside the primary telescopic frame 6110 for controlling the rotation of the lead screw. That is, the primary drive unit 6112 is a motor and is mounted inside the primary telescopic frame 6110. Its output end is connected to the primary lead screw 6113 to drive the primary lead screw 6113 to rotate, thereby driving the primary slider 6111 to move linearly.

[0192] Please refer to Figure 15 In some embodiments, the secondary telescopic arm 622 further includes at least one secondary lead screw 6223, which is rotatably mounted inside the secondary telescopic frame 6220. The secondary slider 6224 is threadedly engaged with the secondary lead screw 6223. The secondary drive component 6221 is a motor and is mounted inside the secondary telescopic frame 6220 for controlling the rotation of the lead screw. That is, the secondary drive component 6221 is a motor and is mounted inside the secondary telescopic frame 6220 to drive the secondary lead screw 6223 to rotate, thereby moving the secondary slider 6224.

[0193] Therefore, the controller controls the rotation of the first-stage motor, which drives the first-stage slider 6111 to move via the lead screw, thus achieving the first-stage extension and retraction. At the same time, it controls the rotation of the second-stage motor, which drives the second-stage slider 6224 to move via the lead screw, thus achieving the second-stage extension and retraction. The lead screw drive has a self-locking characteristic, which can maintain the position unchanged after power failure to prevent accidental movement. In addition, the lead screw drive can achieve high-precision position control and high repeatability.

[0194] In one specific embodiment, the motor and lead screw can be integrated inside the telescopic frame, saving space.

[0195] Please refer to Figure 14 In some embodiments, the card-grabbing component 62 includes a card-grabbing component base 621, which is fixedly connected to the secondary rotating shaft 6225 via a card-grabbing component connecting rod 623. The card-grabbing component base 621 is equipped with at least one grasping electromagnet 624, that is, the card-grabbing component base 621 is fixedly connected to the secondary slider 6224, serving as the mounting base for the card-grabbing component 62. The grasping electromagnet 624 is mounted on the card-grabbing component base 621 and generates magnetic force when energized, which can attract the ferromagnetic material inside the mahjong tile. When it is necessary to grasp the mahjong tile, the controller energizes the grasping electromagnet 624, and the electromagnet generates magnetic force to attract the mahjong tile. After moving to the target position, the power is turned off and demagnetized, and the mahjong tile is released. The attraction force of the electromagnet can be adjusted by the current to adapt to tiles of different weights. The electromagnet only needs to be controlled by turning on and off, without the need for complex transmission, and makes full use of the magnetic structure inside the mahjong tile, reducing the cost of setting up additional structures.

[0196] In one specific embodiment, the card-grabbing base 621 is provided with a U-shaped card-grabbing mounting seat 625, and electromagnets are provided on both sides of the U-shaped card-grabbing mounting seat 625, which enables the card-grabbing device 62 to grab two or four mahjong tiles at a time, thereby improving card-grabbing efficiency and reducing player waiting time.

[0197] Please refer to Figure 14In some embodiments, the card-grabbing component 62 further includes a card-grabbing component 62 mounting base and a card-grabbing component drive motor 626. The card-grabbing component 62 mounting base is rotatably mounted on the card-grabbing component base 621. There are four grabbing electromagnets 624, which are evenly distributed around the rotation axis of the card-grabbing component 62 mounting base. The card-grabbing component drive motor 626 is mounted on the card-grabbing component base 621 and is used to drive the card-grabbing component 62 mounting base to rotate. That is, by using four grabbing electromagnets 624, four, two, or one mahjong tile can be grabbed as needed, thereby improving the efficiency of grabbing and arranging tiles.

[0198] In this specific implementation, a pivot is provided between the mounting base of the card grabber 62 and the base 621 of the card grabber, and the rotation of the mounting base of the card grabber 62 relative to the base 621 is achieved through the pivot.

[0199] In one specific embodiment, the card-grabbing drive motor 626 is directly fixed to the card-grabbing base 621, and its output end is fixedly connected to the card-grabbing mounting base 62, thereby realizing the control of the rotation of the card-grabbing mounting base 62.

[0200] Please refer to Figure 16 In some embodiments, the primary telescopic arm 611 further includes a primary rotating shaft 6115 and a primary rotating drive 6114. The primary rotating shaft 6115 is rotatably mounted on the primary slider 6111. The secondary telescopic frame 6220 is fixedly connected to the end of the primary rotating shaft 6115 away from the primary slider 6111. The primary rotating drive 6114 is mounted on the primary slider 6111 and is used to drive the primary rotating shaft 6115 to rotate. That is, the primary rotating drive 6114 can drive the secondary telescopic arm 622 to rotate around the primary rotating shaft 6115, so that the card-grabbing component 62 can approach the mahjong tiles at different angles and adapt to complex paths. For example, when it is necessary to grab a card from the card-grabbing track, it rotates to the card-grabbing track direction; when it is necessary to place the card into the card-sorting track, it rotates to the track direction.

[0201] Meanwhile, the secondary telescopic arm 622 also includes a secondary rotating shaft 6225 and a secondary rotating drive component 6222. The secondary rotating shaft 6225 is rotatably mounted on the secondary slider 6224, and the secondary rotating drive component 6222 is mounted on the secondary slider 6224 and is used to drive the secondary rotating shaft 6225 to rotate. The card gripper 62 also includes a card gripper 62 connecting rod, which is fixedly connected to the end of the secondary rotating shaft 6225 away from the secondary slider 6224. That is, the secondary rotating drive component 6222 can drive the card gripper 62 to rotate around the secondary rotating shaft 6225. Combined with the primary rotation, the card gripper 62 can adjust its posture in multiple planes, achieving flexibility similar to an articulated robot. For example, the pitch angle or rotation angle of the card gripper 62 can be adjusted to adapt to tracks or temporary stops of different heights. The posture of the card gripper 62 can be finely adjusted to ensure that the electromagnet is parallel to the card surface for adsorption. At the same time, the multi-stage rotation method can be flexibly adjusted in a narrow space to avoid collisions.

[0202] Please refer to Figure 7 In some embodiments, the card feeding assembly 5 further includes a card arranging drive mechanism and a card grabbing drive mechanism. Specifically, the two ends of the card feeding track 51 are connected to the card outlet 111 and the card stacking assembly 4, respectively. The middle of the card feeding track 51 is provided with a card feeding baffle arranged along the trajectory direction of the card feeding track 51. The card feeding baffle divides the card feeding track 51 into an independent card arranging track 512 and a card grabbing track 511. The card arranging drive mechanism is used to push the mahjong tiles to move along the card arranging track 512 and from the card outlet 111 to the surface of the top plate 11. The card grabbing drive mechanism is used to push the mahjong tiles to move along the card grabbing track 511 and from the card outlet 111 to the surface of the top plate 11.

[0203] It should be noted that, in this invention, the top plate 11 is a component of the mahjong machine tabletop, and it has a card outlet 111 for outputting the sorted mahjong tiles to the tabletop for players to pick up. The card stacking component 4 is located below the top plate 11 and is used to stack the shuffled mahjong tiles neatly and transport them to the entrance of the card delivery track 51.

[0204] In addition, the baffle in this invention can be a fixed baffle or an adjustable baffle, that is, the height of the baffle can be adjusted to accommodate mahjong tiles of different sizes.

[0205] In a specific implementation of this invention, the two ends of the card-feeding track 51 are connected to the card-dispensing port 111 and the card-stacking assembly 4, respectively, forming a conveying channel for mahjong tiles from the card-stacking assembly 4 to the card-dispensing port 111, so that mahjong tiles can be conveyed to the table of the mahjong machine along the card-feeding track 51. A card-feeding baffle 513 is provided in the middle of the card-feeding track 51, arranged along the trajectory direction of the track 51. The card-feeding baffle 513 divides the card-feeding track 51 into an independent card-sorting track 512 and a card-grabbing track 511. The two tracks are parallel and adjacent, and are used for conveying mahjong tiles with different functions. The card-sorting drive mechanism 52 is used to push... The mahjong tiles move along the tile arrangement track 512 and from the tile outlet 111 to the top plate surface. The tile grabbing drive mechanism 53 is used to push the mahjong tiles along the tile grabbing track 511 and from the tile outlet 111 to the top plate surface. The tile arrangement track 512 and the tile grabbing track 511 work independently and do not interfere with each other. At the same time, the two drive mechanisms can be controlled independently to realize the parallel processing of the tile arrangement and tile grabbing processes, which improves the system efficiency. The arranged mahjong tiles and the mahjong tiles available for players to grab are simultaneously sent out from the tile outlet 111 for players to pick up, which lays the foundation for saving players' tile arrangement time and greatly enhances the player's experience.

[0206] Please refer to Figure 7In some embodiments, the card delivery track 51 includes a card arranging section and a card dispensing section. The card arranging section is a straight structure, and the card dispensing section is a curved structure. The end of the card dispensing section away from the card arranging section extends to the card dispensing opening 111 and is at the same horizontal height as the upper surface of the top plate. The straight design facilitates the neat arrangement of cards and also facilitates the card arranging mechanism 6 to pick up or put cards from the track. The curved design allows the cards to smoothly turn from the horizontal conveying direction and finally emerge from the card dispensing opening 111 in the correct posture. There is a height difference of no more than 1 mm between the end of the card dispensing section and the upper surface of the top plate, that is, the end of the card dispensing section is lower than the upper surface of the top plate. The card dispensing opening of the top plate is provided with a chamfer facing the end of the card dispensing section. At the same time, the mahjong tiles themselves also have smooth edges. Therefore, this structure can ensure that the tiles can smoothly transition to the table when they are pushed out, without steps or jamming, ensuring the smooth push out of the mahjong tiles. The curved design also avoids the tiles tipping over or getting stuck due to sharp turns.

[0207] In one specific embodiment, the card-playing section has a curved structure with varying height to accommodate the height changes of the mahjong tiles as they rise from the bottom to the tabletop.

[0208] In one specific embodiment, the height of the portion of the card-feeding baffle 513 located in the card-arranging section is 1.2-1.5 times the thickness of the mahjong tiles. For example, if the thickness of the mahjong tiles is 20mm, the height of the baffle is 24mm-30mm. When the mahjong tiles are arranged in the card-arranging track 512, the baffle forms a lateral constraint on the tiles, preventing the tiles from tilting due to vibration or pushing force. The height of 1.2-1.5 times ensures that the baffle can cover most of the height of the mahjong tiles, while leaving a certain margin to avoid interference when the card-arranging mechanism 6 grabs the mahjong tiles, thus ensuring the stability of the mahjong tile grabbing.

[0209] Please refer to Figure 7 In some embodiments, the card feeding assembly 5 further includes a mounting frame 54, which is mounted on the mahjong machine. The card sorting drive mechanism 52 includes a card sorting head thread wheel 521, a card sorting end thread wheel 525, a card sorting thread groove 523, a card sorting drive line, a card sorting pusher 522, and a card sorting drive member 524. The card sorting head thread wheel 521 is rotatably mounted on the mounting frame 54 and located at the end of the card feeding track 51 near the stacking assembly 4. The card sorting end thread wheel 525 is rotatably mounted on the mounting frame 54 and located at the end of the card feeding track 51 near the stacking assembly 4. At the end of the card feeding track 51 near the card outlet 111, the card sorting groove 523 is provided on the card sorting track 512 and arranged along the track 512. The card sorting drive line is wound around the card sorting head pulley 521 and the card sorting tail pulley 525 and is located in the card sorting groove 523. The card sorting pusher 522 is slidably installed in the card sorting groove 523 and is fixedly connected to the card sorting drive line. The card sorting drive 524 is used to control the rotation of the card sorting head pulley 521 and / or the card sorting tail pulley 525.

[0210] That is, the mounting bracket 54 is fixedly installed inside the mahjong machine, serving as the supporting foundation for the entire drive mechanism. The card-sorting drive component 524 drives the drive wheel to rotate, causing the card-sorting drive line to circulate within the card-sorting groove 523. The card-sorting push component 522 moves along with the drive line. In the initial position, the card-sorting push component 522 moves to the track entrance end. At this time, the card-sorting drive component 524 drives the drive wheel to rotate, causing the card-sorting push component 522 to contact and push the mahjong tiles along the track towards the exit end, and finally eject them from the tile outlet 111. The drive wheel and drive line can achieve long-distance tile pushing. The drive wheel and drive line are inexpensive and easy to maintain. Furthermore, the position of the push component on the drive line is fixed, allowing for precise control of the tile pushing distance.

[0211] In one embodiment, the card-sorting pusher 522 is slidably installed in the card-sorting groove 523, and the card-sorting drive line is divided into two segments, which are fixedly connected to the card-sorting head end pulley 521 and the card-sorting tail end pulley 525, respectively, so that when the card-sorting head end pulley 521 and the card-sorting tail end pulley 525 rotate, they drive the ends of the card-sorting drive line to move. The two segments of the card-sorting drive line are fixedly connected to the card-sorting pusher 522, thereby realizing that when the card-sorting head end pulley 521 and the card-sorting tail end pulley 525 rotate, they drive the card-sorting pusher 522 to move.

[0212] Please refer to Figure 7 In some embodiments, the card-sorting drive mechanism 52 includes a first card-grabbing head pulley 531, a first card-grabbing tail pulley 532, a first card-grabbing groove 537, a first card-grabbing drive member 534, a first card-grabbing drive line, and a first card-grabbing push member 539. The first card-grabbing head pulley 531 is rotatably mounted on the mounting frame 54 and located at the end of the card-feeding track 51 near the stacking assembly 4. The first card-grabbing tail pulley 532 is rotatably mounted on the mounting frame 54 and located at the end of the card-feeding track 51 near the card outlet 111. At the end, the first card-grabbing groove 537 is provided on the card-grabbing track 511 and arranged along the trajectory of the card-grabbing track 511. The first card-grabbing drive line is wound around the first card-grabbing head pulley 531 and the first card-grabbing tail pulley 532 and is located in the first card-grabbing groove 537. The first card-grabbing pusher 539 is slidably installed in the first card-grabbing groove 537 and is fixedly connected to the first card-grabbing drive line. The first card-grabbing drive member 534 is used to control the rotation of the first card-grabbing head pulley 531 and / or the first card-grabbing tail pulley 532.

[0213] That is, the first card-grabbing drive 534 drives the pulley to rotate, which in turn drives the first card-grabbing drive line to move, causing the first card-grabbing pusher 539 to move along the card-grabbing track 511, pushing the mahjong tiles from the track entrance to the card-grabbing position near the exit. The first card-grabbing drive 534 is activated when the player's tiles at this position have not been grabbed by the card-sorting mechanism 6. At this time, the end of the mahjong tiles near the first card-grabbing pusher 539 consists of two layers of mahjong tiles, hence the strip structure of the first card-grabbing pusher 539.

[0214] Meanwhile, the card-handling drive mechanism 52 includes a second card-grabbing head pulley 533, a second card-grabbing tail pulley 536, a second card-grabbing groove 538, a second card-grabbing drive component 535, a second card-grabbing drive line, and a second card-grabbing push component 530. The second card-grabbing head pulley 533 is rotatably mounted on the mounting frame 54 and located at the end of the card-feeding track 51 near the stacking assembly 4. The second card-grabbing tail pulley 536 is rotatably mounted on the mounting frame 54 and located at the end of the card-feeding track 51 near the card outlet 111. The second card-grabbing groove 538 is located on the card-grabbing track 511 and is arranged along the track 511. The second card-grabbing drive line is wound around the second card-grabbing head pulley 533 and the second card-grabbing tail pulley 536 and is located in the second card-grabbing groove 538. The second card-grabbing pusher 530 is slidably installed in the second card-grabbing groove 538 and is fixedly connected to the second card-grabbing drive line. The second card-grabbing drive member 535 is used to control the rotation of the second card-grabbing head pulley 533 and / or the second card-grabbing tail pulley 536.

[0215] In one embodiment, two card-grabbing pushers are slidably installed in corresponding card-grabbing grooves, and their corresponding card-grabbing drive lines are each in two segments, which are fixedly connected to the corresponding card-grabbing head pulley and card-grabbing tail pulley, respectively, so that when the card-grabbing head pulley and card-grabbing tail pulley rotate, they drive the ends of the corresponding card-grabbing drive lines to move. The other ends of the two card-grabbing drive lines are fixedly connected to the card-grabbing pushers, thereby realizing that when the card-grabbing head pulley and card-grabbing tail pulley rotate, they drive the card-grabbing pushers to move.

[0216] And please refer to Figure 10 The second card-grabbing pusher 530 has an L-shaped structure, specifically comprising an upper part 5301 and a lower part 5302. The upper and lower parts 5301 are arranged vertically to make the second card-grabbing pusher 530 L-shaped. The length of the upper part 5301 is the same as the width of the mahjong tile. This means the second card-grabbing drive 535 drives the pulley to rotate, causing the second card-grabbing drive line to move, making the L-shaped pusher move along the track. The upper part 5301 contacts the side of the mahjong tile, pushing it forward. Because the length of the upper part 5301 matches the tile width, the tile is pushed smoothly without tilting or jamming.

[0217] This situation is used when the second driving component 535 for grabbing tiles is grabbed by the tile arranging mechanism 6 at the player's position. Specifically, after each player takes their last tile, there will be a gap in one side's tile set. That is, for tile sets stacked one on top of the other, after the tile set is grabbed by the tile arranging mechanism 6, there will be one tile left at the bottom of the set, with no tile above it. At this time, the L-shaped second driving component 530 for grabbing tiles can stop the movement of the last tile of the upper tile set and the last tile below it, thus ensuring that the upper tile set does not slip during the uphill process. At the same time, it ensures that the tile set remains in the state after being jumped after being transported to the table. At the start of the game, the first player to draw a tile can easily and clearly locate the tile drawing position.

[0218] Please refer to Figure 8 In some embodiments, the card delivery track 51 is provided with a shield. The shield is located at the card dispensing part of the card delivery track 51. The shield 55 is installed above or on the side of the card dispensing part of the card delivery track 51, covering the track exit area. The shield can be made of transparent or opaque material. Its function is to prevent the cards from being accidentally exposed before reaching the card dispensing opening 111, or from being interfered with by external foreign objects, so as to ensure the stability of the mahjong cards during the pushing process.

[0219] A method of use for a mahjong machine with a tile-arranging function includes the following steps:

[0220] S1. Preparation and Shuffling Stage: The controller controls the table body drive 122 to drive the table body mounting plate 121 to rotate to the preset working position, closes all card outlets 111, places the mahjong tiles into the shuffling tray 202, and starts the shuffling drive 201 to drive the shuffling tray 202 to rotate for shuffling. The player starts the mahjong machine through the control button on the central plate 82. The controller first controls the table body drive 122 to drive the table body mounting plate 121 to rotate to the preset working position (such as the shuffling position) and confirms that all card outlets 111 are closed. The player puts the mahjong tiles into the shuffling tray 202 through the opening on the top plate 11. The controller starts the shuffling drive 201, and the shuffling tray 202 starts to rotate, thoroughly shuffling the mahjong tiles.

[0221] S2, Card Delivery Stage: After shuffling, the controller controls the card transport drive 301 to drive the card transport conveyor belt 302 to transport the mahjong tiles to the stacking assembly 4. The drive unit drives the mahjong tiles to move along the grabbing track 511 to the predetermined position. The controller controls the card transport drive 301 to start. The card attraction magnet on the card transport drive wheel 303 attracts the mahjong tiles on the shuffling tray 202 to the card transport conveyor belt 302. The conveyor belt transports the tiles to the receiving plate of the stacking assembly 4. The stacking drive controls the receiving plate to gradually descend to stack the mahjong tiles. The push drive controls the push plate to push the stacked mahjong tiles along the grabbing track 511 to the predetermined position, waiting to be grabbed. At the same time, the sorting track 512 remains unloaded, ready to receive the sorted tiles.

[0222] S3. Determine the starting point for drawing cards: The player clicks the control button to make the controller determine the starting point for drawing cards. The controller controls the table body drive component 122 to drive the table body mounting plate 121 to rotate to the position corresponding to the player in the preset program. The player rolls the dice by controlling the button on the central plate 82 and determines the position for drawing cards (such as the dealer) according to the dice roll. The controller controls the table body drive component 122 to drive the table body mounting plate 121 to rotate according to the selection, so that the starting end of the corresponding card drawing track 511 is aligned with the player's position.

[0223] S4. The controller controls the tile sorting mechanism 6 to grab the mahjong tile from the corresponding position of the tile grabbing track 511 and transfer it to the temporary stop plate 7. The rotation drive 632 moves the multi-stage telescopic arm 61 toward the end of the tile grabbing track 511. The lifting drive 631 is adjusted to a suitable height. The multi-stage telescopic arm 61 extends so that the tile grabbing component 62 reaches directly above the mahjong tile. The tile grabbing component 62 grabs the corresponding mahjong tile. Then the telescopic arm retracts. The rotation drive 632 rotates again to transfer the mahjong tile to the top of the temporary stop plate 7. The tile grabbing component 62 releases the mahjong tile, and the tile is placed stably on the temporary stop plate 7.

[0224] S5, Tiles Arranging Stage: The tiles arranging camera 81 captures images of the mahjong tiles on the temporary stop plate 7, identifies the suit and number of the mahjong tiles, and sends the identification results to the controller. Based on the identification results and preset tiles arranging rules, the controller controls the tiles arranging mechanism 6 to rearrange all the mahjong tiles on the temporary stop plate 7 into the tiles arranging track 512 in a preset order. The controller determines the corresponding position of the tile in the tiles arranging track 512 according to the preset tiles arranging rules (such as according to player order, suit, number, etc.), and then controls the tiles arranging mechanism 6 to act again, grab the tile from the temporary stop plate 7, and accurately place the tile into the corresponding position in the tiles arranging track 512 through rotation, lifting, and extension movements according to the target position. S4-S5 are repeated until all tiles are identified and arranged in the tiles arranging track 512, thus achieving automatic tiles arranging.

[0225] S6. Playing Stage: After the tiles are arranged, the tile outlet 111 is opened. The controller controls the drive unit to output the mahjong tiles on the tile arranging track 512 and the mahjong tiles on the tile grabbing track 511 from the corresponding tile outlet 111 for the player to grab. The controller controls the tile outlet drive unit 132 to start, and opens the corresponding tile outlet cover plate 131 through the linkage mechanism. At the same time, the drive unit starts to output the mahjong tiles on the tile arranging track 512 and the remaining mahjong tiles on the tile grabbing track 511 from the corresponding tile outlet 111. The player can directly take the arranged tiles. After playing the tiles, the tile outlet cover plate 131 is closed, completing one work cycle.

[0226] In one specific embodiment, the controller can support multiple card arrangement modes, such as sorting by suit, sorting by number, or sorting by player-defined order. Players can select these modes via the central disk 82, which can be achieved by pre-implanting various programs into the controller.

[0227] Therefore, the high-speed movement of the robotic arm and the parallel processing of visual recognition make the time for arranging the entire deck of cards much shorter than that of manual operation. Visual recognition ensures accurate card information, the robotic arm has high positioning accuracy, and the card arranging order completely conforms to the preset rules. Players only need to start with one button and select the starting point to directly retrieve the arranged cards after the game ends. This enhances the user experience of the automatic intelligent entertainment terminal for mahjong machines, allowing players to truly enjoy a relaxed and efficient entertainment experience. It has extremely high market value and industrial prospects.
