[ technical field ] A method for producing a semiconductor device

The invention belongs to the field of mahjong machine manufacturing, and particularly relates to a mahjong machine, a tile feeding assembly and a tile feeding driving mechanism of the mahjong machine.

[ background of the invention ]

Along with the continuous improvement of the living standard, people pay more and more attention to leisure and entertainment life, and the convenient and labor-saving automatic mahjong machine is gradually loved by people.

The patent document with publication number CN200966910Y discloses a slope card-playing device for a full-automatic mahjong machine, which comprises a table board, wherein a card-playing port is arranged at the center of the table board, four rectangular card-playing ports in windmill shape are arranged on the table board, the card-playing ports and the side line of the table board are inclined at an angle, four arc card-storing grooves which are also arranged in windmill shape are arranged below the table board, a card-sending pushing head is arranged at the tail end of each card-storing groove, the pushing head is connected with a pushing head motor through a card-sending steel wire rope, a supporting plate door strip is arranged on each card-playing port, one end of each supporting plate door strip is hinged with the card-playing port, and the other end of each supporting plate door strip is movably connected with a lifting mechanism. The four card outlets are arranged in a windmill shape, and each card outlet is inclined at an angle with the bottom edge of the table, namely the windmill shape is inclined, so that the table top can be made smaller, and the inclination of the card strips also conforms to the habits of players; secondly, when the mahjong is played, the whole mahjong pier is not built and then is lifted on the table top, but is pushed on the table top along the slope, so that the space in the machine can be reduced, and the volume of the whole machine can be reduced. However, in the card-delivering device, the whole card storage groove is arranged in a slope shape, the resistance in the card-delivering process is large, the load of a steel wire rope motor is large, a steel wire is easy to shake and break, the card-delivering process is not stable enough, the service life of the steel wire rope is short, the arrangement of the card storage groove, the stacking and pushing machine head and the conveying device (a mechanism for picking up mahjong tiles from a large disk and conveying the mahjong tiles to the stacking and pushing machine head) is unreasonable, the conventional four-side independent stacking and pushing machine head is difficult to push the mahjong tiles to the card inlet of the card storage groove track, and the height of the main machine is high.

Patent document No. CN201783185U discloses a chain-driven slope tile discharging device for a full-automatic mahjong machine, which comprises four liftable tile lifting plates hinged with a tabletop, wherein one end of each tile lifting plate is a tile inlet, a conveying belt is arranged on the outer side of each tile lifting plate, a stacking and pushing mechanism is arranged on one side of each conveying belt, an arc-shaped tile storage groove is arranged on the outer side of each conveying belt, an annular closed chain is arranged below each groove, and vertical chain rods are arranged on each chain at set intervals. Although the mahjong tile discharging device adopts the chain to push the mahjong tiles, the problem of short service life of a steel wire rope is solved, the working noise of the machine is high, the plane size of a main machine is increased, and other defects are not improved.

Patent document CN102133480A discloses a full-automatic mahjong machine, which comprises a mahjong conveying system, a mahjong loading system, a mahjong lifting system and a mahjong shuffling large disk, wherein the mahjong loading system comprises four mahjong pushing devices, four mahjong loading rails and a chain transmission device. The height of the card sending system is basically equal to that of the card lifting system, so that although the height of the host computer is reduced, the arrangement position of the card lifting system can interfere with the large-disk shuffling and the card sending system to suck mahjong, and the card sending system is only suitable for small mahjong. Moreover, the arrangement of the mahjong outlet of the mahjong conveying system and the mahjong inlet of the mahjong loading track is unreasonable, the mahjong pushing device does not have the mahjong stacking function, mahjong tiles are automatically stacked on the mahjong bearing table surface, and therefore the mahjong tiles are not stacked neatly and are easy to move and misplace, and the mahjong tiles cannot enter the mahjong loading track, and are disordered in the mahjong loading track. In addition, after the horizontal mahjong tile feeding track is adopted, mahjong tiles close to the mahjong tile discharging port of the mahjong tile feeding track are very easy to fall out of the mahjong tile discharging port and fall back to the large shuffling tray; the chain and the mahjong-serving flag wheel are adopted, so that the noise is high.

In the automatic mahjong machine disclosed in patent documents with publication numbers CN201906453U and CN201949619U, the mahjong storage plate in the mahjong storage track of the mahjong machine is obliquely arranged, one end of the mahjong storage plate is butted with the mahjong bearing plate, the mahjong tiles on the mahjong bearing plate are pushed onto the mahjong storage plate by the mahjong stacking and pushing head, and after the mahjong tiles on the mahjong storage plate are arranged in a row, the mahjong stacking and pushing head pushes the whole row of mahjong tiles to the mahjong tile loading assembly; because the dodging groove is formed in the stacking card pushing head, and the push rod is arranged on the upper card pushing head, the two pushing heads can be arranged in a vertically crossed mode, and the stacking card pushing head and the upper card pushing head can be completely avoided through the dodging groove when pushing cards respectively. However, since the card holding path passes above the conveying section of the card feeding device, the height of the main machine of the mahjong machine is high (the heights of the card feeding device and the card loading device are overlapped), and the L-shaped card holding path is short, so that the universality is poor.

The automatic mahjong machine disclosed in the patent documents CN103861280A and CN104645608A also has the problems of high main machine height (height superposition of the card delivering device and the card loading device), short L-shaped card storing track, and the like. Moreover, after the horizontal mahjong tile feeding track is adopted, mahjong tiles close to the mahjong tile discharging port of the mahjong tile feeding track are very easy to fall out of the mahjong tile discharging port and fall back to the large shuffling tray; the wire rope is adopted to drive the mahjong tile pushing head to move, the wire rope and the side wall of the track are seriously rubbed, and the service life is short.

The patent document with publication number CN204699375U discloses an automatic mahjong machine with an improved structure, which comprises a mahjong conveying system, a mahjong loading system, a mahjong lifting system and a large shuffling tray, wherein the mahjong conveying system comprises four mahjong conveying mechanisms, each mahjong conveying mechanism comprises a transmission frame and a conveying belt fixed on the transmission frame, the four mahjong conveying mechanisms are sequentially connected to form a rectangular structure, and the large shuffling tray is arranged in the four mahjong conveying mechanisms. The mahjong tile feeding tracks are all of large arc structures, friction force between mahjong tiles and the mahjong tile feeding tracks is reduced, and high mahjong tile feeding speed and low mahjong tile feeding noise are guaranteed. And moreover, the arrangement positions of the card feeding system and the card delivering system are subjected to avoidance partial overlapping design, so that the height of the host is reduced. However, because the tile feeding device adopts a straight line to feed and discharge the mahjong tiles, the tile outlet of the tile feeding device and the tile inlet of the tile feeding track cannot be reasonably arranged, the tile pushing resistance of the stacking and pushing device is large, the tiles are easy to be clamped, and the size of the table top of the mahjong machine is increased due to the large arc-shaped tile feeding track.

The patent document with publication number CN105413161A discloses a tile feeding driving mechanism, a tile feeding assembly and a mahjong machine, the tile feeding driving mechanism of the mahjong machine comprises a tile feeding support, a tile storage groove, a tile feeding guide rail, a tile feeding pushing head and a steel wire rope, a rolling member is arranged at the position where the steel wire rope is close to the tile feeding guide rail and/or the tile storage groove, the rolling member is rotatably arranged on the tile feeding guide rail or the tile feeding support, and the part of the steel wire rope in the tile storage groove is in rolling contact with the rolling members and keeps a gap with the side walls of the tile feeding guide rail and/or the tile storage groove. The scheme replaces the sliding friction of the steel wire rope in the prior art with the rolling friction of the steel wire rope, so that the running friction resistance of the steel wire rope is greatly reduced, and the influence on the service life and the running stability of the steel wire rope caused by the sliding friction contact of the part of the steel wire rope in the mahjong tile storage groove and the arc-shaped bent side wall of the mahjong tile feeding guide rail and/or the mahjong tile storage groove is avoided.

Therefore, in the prior art, most of the mahjong tile feeding driving mechanisms adopt a steel wire rope driving structure or a chain driving structure. However, because the length of the card storage groove is long and the card feeding pushing head is curved in an arc shape, and the card feeding pushing head is in sliding friction contact with the card feeding guide rail, the problems that the resistance of the card feeding pushing head is large, the number of the pushed cards is limited, the load of a motor is large and the like exist in practical use.

Therefore, the mahjong tile pushing device not only realizes respective reciprocating motion and mutual matching and alternate mahjong tile pushing of the two mahjong tile feeding push rods, but also has simple and reasonable structure, utilizes the existing structural layout to the maximum extent, reduces the manufacturing cost and ensures the product reliability.

In this embodiment, as shown in fig. 2, the first gear 508 is disposed below, the first link 504 is disposed in the middle, the first card-handing push rod 503 is disposed above, the second gear 505 is disposed below, the second link 506 is disposed in the middle, and the second card-handing push rod 507 is disposed above. The outer ends of the first tile feeding push rod 503 and the second tile feeding push rod 507 are higher than the inner side wall of the tile storage groove 502 and higher than the height of the mahjong tiles stored in the tile storage groove 502. Therefore, the mutual interference of the gear link mechanism is avoided, the two mahjong tile feeding push rods are ensured to swing above the mahjong tiles in the tile storage groove, and the height increase of a main machine of the mahjong machine is reduced as much as possible. As shown in fig. 3 and 4, the first tile feeding pushing head 5033 is fixedly connected to or integrally formed with the outer end of the first tile feeding pushing rod 503, the rotation fulcrum 5031 of the first tile feeding pushing rod is an inner end thereof, the hinge joint 5032 of the first tile feeding pushing rod and the first connecting rod is arranged at a position close to the rotation fulcrum in the middle of the first tile feeding pushing rod, the second tile feeding pushing head 5073 is hinged to the outer end of the second tile feeding pushing rod 507 through a pin shaft, the rotation fulcrum 5071 of the second tile feeding pushing rod is an inner end thereof, and the hinge joint 5072 of the second tile feeding pushing rod and the second connecting rod is arranged at a position close to the rotation fulcrum in the middle of the second tile feeding pushing rod. As shown in fig. 1, the transmission ratio of the first gear 508 and the second gear 505 is 1, when the first card-handing push head 5033 is located outside the card inlet of the card storage slot 502, the second card-handing push head 5073 is located in the card storage slot 502, and the connection line a between the rotation fulcrum 5031 of the first card-handing push rod and the first card-handing push head 5033 and the connection line B between the rotation fulcrum 5071 of the second card-handing push rod and the second card-handing push head 5073 form an angle a of 150 ° to 200 ° (preferably 150 ° to 155 °), the swing angle of the first card-handing push rod 503 (from the outside of the card inlet of the card storage slot 502 to the vicinity of the gap where the card storage slot 502 communicates with the reversing slot 509) is 90 ° to 150 °, and the swing angle of the second card-handing push rod 507 (from the reversing slot 509 to the card outlet of the card storage slot 502) is 120 ° to 180 °. In order to avoid and ensure a large pushing force, the first card pushing rod 503 and the second card pushing rod 507 are both bent arms (or L-shaped), for example, as shown in FIG. 1, the card storage groove pushes cards clockwise, and the first card pushing rod 503 and the second card pushing rod 507 are both bent clockwise. The first connecting rod and the second connecting rod are both provided with avoidance grooves for avoiding the fixing position (rotating fulcrum) of the mahjong loading push rod.

In the above expression, the front and back of the second tile pushing head 5073 are distinguished according to the moving direction, the moving forward direction is front, and vice versa; the second pushing head 5073 is in a standing state in a free state, as shown in fig. 4, 7 and 8, i.e. in a falling and pushing state, the second pushing head 5073 can only be lifted to one side (i.e. when passing over a mahjong tile, the second pushing head 5073 is passively rotated to the back and the upper side), and the limit structure can not be lifted to the other side (used for pushing the mahjong tile). The active return of the second card pushing head 5073 to the upright state means that the second card pushing head 5073 returns to the upright state under the action of gravity or an elastic member. The above-mentioned limit structure means that one side of the second tile pushing head 5073 which is erected abuts against the second tile pushing rod 507, and the erection does not mean a vertical state, but means that the second tile pushing head is lifted up, and the second tile pushing head is dropped and erected. The shape of the above-mentioned reversing slot can be various, in this embodiment, as long as the second card-pushing head can be recovered to the vertical state from the lifted state in the reversing slot, so the reversing slot is not limited to the groove in the conventional sense, and can also be an open accommodating space. For the gap between the card storage slot and the reversing slot, the second card pushing head 5073 in the vertical state can freely enter and exit, and the mahjong tiles in the card storage slot are prevented from being embedded into the gap.

The mahjong storage groove is approximately U-shaped, can be composed of a plurality of arc-shaped bent sections and a plurality of straight sections, and can also be a large arc-shaped bent as shown in CN204699375U, but the size of the tabletop of the mahjong machine is increased. In this embodiment, the card storage slot has two arc-shaped bending sections which are respectively suitable for the rotating paths of the two card pushing heads. Sensors are arranged outside the card inlet and the card outlet of the card storage groove and used for detecting whether the card pushing head moves in place or not, and the sensors can be Hall sensors or photoelectric sensors.

In order to reduce the frictional resistance between the mahjong tiles and the bottom of the tile storage groove and simultaneously not increase the cost greatly, the bottom of the tile storage groove is provided with a tile storage groove bottom patch, and the tile storage groove bottom patch is preferably made of materials with smooth and wear-resistant surfaces, such as polyformaldehyde, polytetrafluoroethylene and the like. The bottom paster of the mahjong storage groove is used as an independent part to be installed in the mahjong storage groove of the mahjong serving support, and the mahjong serving support is made of materials with poor performance and low price, so that the use requirement can be met, and the manufacturing cost of a machine can be reduced. The storage card slot bottom patch is preferably matched and positioned with the card feeding support through a plurality of buckles and is locked and fixed through a fastener, so that the storage card slot bottom patch is convenient to mount. Similarly, in order to reduce the friction resistance between the mahjong tiles and the inner side wall and the outer side wall (especially the side wall of the arc-shaped bent section) of the mahjong tile storage groove without greatly increasing the cost, part or all of the inner side wall and/or the outer side wall of the mahjong tile storage groove is provided with a side wall patch, and the side wall patch is preferably made of materials with smooth and wear-resistant surfaces, such as polyformaldehyde, polytetrafluoroethylene and the like.

The mahjong storage groove can be made into a slope form with a relatively slow slope from the mahjong inlet to the mahjong outlet, but the mahjong pushing resistance of the mahjong pushing head can be increased. In addition, store up the tablet groove and be equipped with the slope from a certain extent, thereby can also play the extension and rise tablet layer board length in the tablet subassembly, slow down and rise the effect that tablet layer board slope degree of slope reduces the tablet resistance of going up. The mahjong tile playing slope can be formed at the bottom of the mahjong tile storage groove, but is preferably arranged on the bottom patch of the mahjong tile storage groove, namely most of the bottom patch of the mahjong tile storage groove is horizontally arranged, and the mahjong tile playing slope surface capable of lifting mahjong tiles is formed at the position, close to the mahjong tile playing opening of the mahjong tile storage groove, of the bottom patch of the mahjong tile storage groove. The bottom patch of the mahjong storage groove is provided with a mahjong inlet slope surface at the mahjong inlet of the mahjong storage groove for the mahjong to enter. In order to avoid the faults of arching, jumping and the like of mahjong tiles in the tile storage groove in the tile pushing process of the tile pushing device, a tile pressing plate for limiting the height of the tile storage groove is arranged above the tile storage groove on the tile feeding support 501, and the tile pressing plate covers part or all of the top of the tile storage groove.

In order to avoid the vertical displacement of the mahjong tiles on the table top of the mahjong machine, the horizontally moving second mahjong tile pushing head 5073 is provided with a plurality of tile pushing parts which are respectively contacted with two mahjong tiles stacked up and down in the same pier, wherein the tile pushing part contacted with the lower mahjong tile is protruded out of the tile pushing part contacted with the upper mahjong tile, so that when the second mahjong tile pushing head 5073 pushes the plurality of mahjong tiles to horizontally move, the upper mahjong tile lags behind the lower mahjong tile, and when the second mahjong tile pushing head 5073 pushes the last mahjong tile to the inclined tile lifting supporting plate, the upper mahjong tile is level with the lower mahjong tile.

As shown in fig. 9, 10 and 11, in order to avoid the first tile pushing head from colliding with the tile pushing head 401 of the tile pushing device outside the tile inlet of the tile storage slot and blocking the mahjong tiles sent by the tile sending device, the first tile pushing head 5033 and the tile pushing head 401 of the tile pushing device are in a staggered and avoiding design and are arranged on one side of the tile bearing platform 402 together with the tile pushing head 401 before the tile pushing. In order to avoid the situation that mahjong tiles pushed by the tile pushing device are easily scattered and jammed, as shown in fig. 9, the tile feeding direction of the tile inlet of the tile storage groove and the tile discharging direction of the tile outlet of the tile feeding device form an included angle of 80-100 degrees, and the tile pushing direction of the tile pushing head 401 of the tile pushing device 4 is matched with the tile feeding direction of the tile inlet of the tile storage groove to be consistent.

In the card picking and conveying system, the matching arrangement relationship among the card storage groove in the card loading assembly, the card bearing platform in the card pushing device and the conveying channel in the card sending device is particularly important, and the matching arrangement relationship determines the action process of the card pushing device.

In one embodiment of the invention, as shown in fig. 12-15, the height of the card inlet of the card storage slot is lower than the height of the card outlet of the card sending device and the height difference M between the two is larger than the height of one mahjong card and smaller than the height of two mahjong cards, preferably 21-33 cm. Thus, as shown in FIG. 12, the deck 402 receives the first tile 10 at an initial position slightly below the outlet of the delivery device; then, the mahjong tile pushing head 401 pushes the stacked mahjong tiles into the tile inlet of the tile storage groove 502, as shown in fig. 15 and fig. 11. Finally, the deck 402 is raised to the home position to await the next tile as shown in FIG. 12.

In another embodiment of the present invention, as shown in figures 16 to 20, the height of the inlet of the storage chute is lower than the height of the outlet of the card delivery device and the difference M between the heights is less than the height of one mahjong piece, preferably 1 to 13 cm. Thus, as shown in FIG. 16, the deck 402 receives the first tile 10 at an initial position slightly below the outlet of the card delivery device; then, the mahjong machine descends by a certain height to receive a second mahjong tile, as shown in figures 17 and 18; then the support platform 402 is lifted to the initial position, at which time the support platform is close to the height of the card inlet of the card storage slot, as shown in fig. 19; the card pushing head 401 pushes the piled mahjong into the card inlet of the card storage slot 502, as shown in fig. 20 and fig. 11, after the card pushing head 401 retreats, the next mahjong is waited to be connected.

The two embodiments can ensure that the actions of the card bearing platform and the card pushing head in the card pushing device are simple and reasonable, and the reliability is better. Because the mahjong tile feeding push rod is required to be arranged above mahjong tiles in the tile storage groove, the height of the mahjong tile feeding assembly can be increased, when the height of the mahjong tile feeding assembly affects the overall height of a main machine of the mahjong machine, the first implementation mode can be adopted, and the height of the mahjong tile feeding assembly can be reduced. In the second embodiment, the difference between the height of the card inlet and the height of the card outlet of the card storage groove is small, and the card storage groove structure which is basically horizontal can be adopted, so that the problem of increasing the card feeding resistance is solved.

When the card storage slot in the card feeding assembly stores enough mahjong, the card feeding assembly starts to feed cards: as shown in fig. 5, the first pushing rod 503 is rotated towards the inlet of the storage slot 502, the first pushing head 5033 pushes the mahjong tiles in the storage slot to be pushed, the second pushing rod 507 is rotated towards the reversing slot 509, and the second pushing head 5073 is lifted passively to pass above the mahjong tiles in the storage slot; as shown in fig. 6, the second card-feeding pusher 5073 enters the reversing slot 509, and the second card-feeding pusher 5073 returns to the card-dropping and pushing state from the lifted state in the reversing slot 509, and at this time, the first card-feeding pusher 5033 has moved to the vicinity of the reversing slot 509; as shown in fig. 7, the first tile feeding pushing head 5033 pushes the last tile in the tile storage slot through the reversing slot 509, the second tile feeding pushing head 5073 enters the tile storage slot 502 from the reversing slot 509 to replace the first tile feeding pushing head 5033 to start pushing the tiles to be fed, and the first tile feeding pushing head 5033 moves out of the tile inlet of the tile storage slot 502; as shown in fig. 8, the second tile feeding pushing head 5073 pushes the tiles out of the tile storage slot and onto the tile lifting pallet, and then starts to move towards the direction of the direction-changing slot 509, the first tile feeding pushing head 5033 moves to one side of the tile bearing platform 402 and is arranged in a staggered manner with the tile pushing head in the tile pushing device to wait for next tile feeding, at this time, the second tile feeding pushing head 5073 stops in the tile storage slot 502, and when the tile pushing device pushes the subsequent tiles into the tile storage slot 502 and touches the second tile feeding head 5073, the second tile feeding pushing head 5073 in the falling and standing state is pushed upwards by the tiles, so that more tiles are not prevented from entering the tile storage slot 502.

One of the control methods of the mahjong machine is as follows:
