Description

Technical Field

[0001] This utility model relates to the field of Go-playing machines and equipment, and more particularly to a Go-playing robot and a Go-playing device. Background Technology

[0002] The go stone feeder is a crucial component in Go-playing robots. To enable automatic stone feeding, patent publication CN117067225A discloses a go stone feeder. This feeder uses a transmission structure to transport the go stones from the lower go stone slot (reference numeral 8 in the document) to the opening (reference numeral 5 in the document). This type of feeder continuously transports the go stones to the opening by the continuous rotation of an output gear (reference numeral 21 in the document). The rotation of the output gear is driven by a synchronous belt (reference numeral 19 in the document). However, during use, the synchronous belt gradually loosens with increasing usage time, leading to a decrease in the reliability of the entire feeder. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a feeding device that uses the cooperation of a gear set and a rack to transport chess pieces. Compared to a synchronous belt, the cooperation between the rack and the gear set is more stable, has a lower probability of loosening during use, and the overall feeding device is more stable in operation.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A feeding device includes a base, a chess box mounted on the base, a feeding port on the chess box, a gear set, a push rod, a one-way shaft, a rotor, and a motor. The gear set is mounted on the base, the push rod is slidably mounted on the base, and the push rod has a rack that meshes with the gear. The one-way shaft is rotatably mounted on the chess box, the rotor is coupled to the one-way shaft, the rotor is located inside the chess box, and the rotor has a notch. The one-way shaft is coupled to the gear set, the push rod has a receiving opening, and the motor shaft is coupled to the gear set.

[0006] The working process of this type of feeder is as follows: First, the motor shaft is coupled with the gear set, so the rotation of the motor shaft drives the gears in the gear set to rotate. The gears in the gear set mesh with the rack, so the rotation of the motor shaft can drive the push rod to move back and forth. At the same time, in this type of feeder, because the unidirectional shaft is coupled with the gear set, the gear set can only drive the unidirectional shaft to rotate in one opposite direction, and cannot make the unidirectional shaft rotate in both directions. When the unidirectional shaft rotates, it can drive the rotor to rotate within the chessboard. When the rotor rotates within the chessboard, the chess pieces placed on the chessboard can fall into the notch. When the rotor rotates to the point where its notch is above the drop port, the chess pieces in the rotor's notch will fall out of the drop port and into the receiving port of the push rod. After the chess pieces fall into the receiving port, the push rod continues to move, and the feeding stops after pushing the chess pieces to the target position.

[0007] In summary, this type of feeder uses the combination of gears and racks to transport chess pieces. Compared with synchronous belts, the combination of racks and gears is more stable, has a lower probability of loosening during use, and the overall feeder is more stable.

[0008] The push rod has two positions: the initial position and the target position. When the push rod is in the initial position, the receiving port, the notch, and the dropping port are roughly in the same position. The chess piece can fall from the notch into the receiving port through the dropping port. When the chess piece falls into the receiving port, the push rod starts to move from the initial position to the target position (the one-way shaft does not rotate during this process). When the push rod reaches the target position and the chess piece is taken out from the dropping port, the push rod moves back to the initial position. The one-way shaft rotates, driving the rotor to rotate. When the push rod returns to the initial position, the chess piece in the notch falls into the receiving port through the dropping port, and then a new round of conveying begins.

[0009] Optionally, it may also include a through-beam photoelectric sensor, which is disposed on the base.

[0010] Specifically, the through-beam photoelectric sensor detects whether there are chess pieces inside the receiving port and whether any pieces have been removed. When the push rod moves to the target position, the through-beam photoelectric sensor illuminates the receiving port to detect whether there are chess pieces inside and whether any pieces have been removed.

[0011] Optionally, it may also include a first position sensor and a second position sensor, both of which are disposed on the base.

[0012] Specifically, when a chess piece is removed from the receiving slot, the photoelectric sensor detects this information. After the photoelectric sensor detects this information, the motor drives the rack to move back to the initial position. During the movement to the initial position, it will be detected by the first position sensor. After the first position sensor detects it, it continues to control the motor to drive the push rod to move back to the initial position (during this process, the rotor is also in a state of rotation driven by the one-way shaft). When the push rod reaches the initial position, it will be detected by the second position sensor, the chess piece will fall into the receiving slot, the motor will reverse, and the push rod will move back to the target position.

[0013] Optionally, the push rod is provided with a position sensing plate.

[0014] The position sensing board is used to trigger the first position sensor and the second position sensor. Specifically, the first position sensor and the second position sensor can be selected as through-beam slot-type optocoupler photoelectric switch sensors.

[0015] Optionally, a baffle is also included, which is disposed inside the chess box and located at the material discharge port.

[0016] The baffle is designed to prevent chess pieces from falling directly into the feed inlet without passing through the rotor's notch.

[0017] Optionally, it also includes a first proximity switch and a second proximity switch, both of which are disposed on the base, and the push rod is located between the first proximity switch and the second proximity switch.

[0018] Specifically, the first proximity switch and the second proximity switch are located at the two extreme positions of the push rod movement. When the push rod touches the first proximity switch or the second proximity switch, the motor stops immediately.

[0019] Optionally, the one-way axis is perpendicular to the push rod.

[0020] A Go-playing robot, including the piece delivery device as described above.

[0021] The beneficial effects of this utility model are: the chess pieces are transported by the cooperation of the gear set and the rack. Compared with the synchronous belt, the cooperation between the rack and the gear set is more stable, the probability of loosening during use is lower, and the working stability of the entire feeder is stronger.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0031] Example 1

[0032] As attached Figure 1 ~Appendix Figure 4As shown, a feeding device includes a base 11, a chess box on the base 11, a feeding port 101 on the chess box, a gear set 8, a push rod 4, a one-way shaft 10, a rotor 2, and a motor 9. The gear set 8 is mounted on the base 11, the push rod 4 is slidably mounted on the base 11, and the push rod 4 is provided with a rack 402 that meshes with the gear. The one-way shaft 10 is rotatably mounted on the chess box, the rotor 2 is engaged with the one-way shaft 10 and is located inside the chess box. The rotor 2 is provided with a notch 201. The one-way shaft 10 is engaged with the gear set 8, the push rod 4 is provided with a receiving port, and the shaft of the motor 9 is engaged with the gear set 8.

[0033] The working process of this type of feeder is as follows: First, the shaft of the motor 9 is engaged with the gear set 8, so the rotation of the shaft of the motor 9 drives the gears in the gear set 8 to rotate. The gears in the gear set 8 mesh with the rack 402, so the rotation of the shaft of the motor 9 can drive the push rod 4 to move back and forth. At the same time, in this type of feeder, since the one-way shaft 10 is engaged with the gear set 8, the gear set 8 can only drive the one-way shaft 10 to rotate in one opposite direction, and cannot make the one-way shaft 10 rotate in both directions. When the one-way shaft 10 rotates, it can drive the rotor 2 to rotate in the chessboard 1. When the rotor 2 rotates in the chessboard 1, it can cause the chess pieces placed in the chessboard 1 to fall into the notch 201. When the rotor 2 rotates to the point where its notch 201 is above the drop port 101, the chess pieces in the notch 201 of the rotor 2 will fall out of the drop port 101 and into the receiving port of the push rod 4. After the chess pieces fall into the receiving port, the push rod 4 continues to move. After pushing the chess pieces to the target position, the feeding stops.

[0034] In summary, this type of feeder achieves the feeding of chess pieces through the cooperation of gear set 8 and rack 402. Compared with synchronous belt, the cooperation between rack 402 and gear set 8 is more stable, the probability of loosening during use is lower, and the overall working stability of the feeder is stronger.

[0035] Specifically, push rod 4 moves to two positions: the initial position and the target position. When push rod 4 is in the initial position, the receiving port, notch 201, and discharge port 101 are roughly in the same position. The chess piece can fall from the notch 201 into the receiving port through the discharge port 101. When the chess piece falls into the receiving port, push rod 4 starts to move from the initial position to the target position (during this process, the one-way shaft 10 does not rotate). When push rod 4 reaches the target position and the chess piece is taken out from the discharge port 101, push rod 4 moves back to the initial position. The one-way shaft 10 rotates, driving the rotor 2 to rotate. When push rod 4 returns to the initial position, the chess piece in the notch 201 falls into the receiving port through the discharge port 101, and then a new round of conveying process begins.

[0036] With attachment Figure 4Taking the direction shown as an example, the initial position is located to the right of push rod 4, and the target position is located to the left of push rod 4.

[0037] As attached Figure 1 ~Appendix Figure 4 As shown, it also includes a through-beam photoelectric sensor 6, which is mounted on the base 11.

[0038] Specifically, the function of the through-beam photoelectric sensor 6 is to detect whether there are chess pieces inside the receiving port and whether the chess pieces have been removed. When the push rod 4 moves to the target position, the through-beam photoelectric sensor 6 can illuminate the receiving port to detect whether there are chess pieces inside and whether the chess pieces have been removed.

[0039] As attached Figure 1 ~Appendix Figure 4 As shown, it also includes a first position sensor 501 and a second position sensor 502, both of which are mounted on the base 11.

[0040] Specifically, when a chess piece is removed from the receiving port, the photoelectric sensor 6 will detect this information. After the photoelectric sensor 6 detects this information, the motor 9 will drive the rack 402 to move towards the initial position. During the movement towards the initial position, it will be detected by the first position sensor 501. After the first position sensor 501 detects it, it will continue to control the motor 9 to drive the push rod 4 to move towards the initial position (during this process, the rotor 2 is also in a state of being driven to rotate by the one-way shaft 10). When the push rod 4 reaches the initial position, it will be detected by the second position sensor 502, the chess piece will fall into the receiving port, the motor 9 will reverse, and the push rod 4 will move towards the target position again.

[0041] As attached Figure 1 ~Appendix Figure 4 As shown, a position sensing plate 403 is provided on the push rod 4.

[0042] The position sensing board 403 is used to trigger the sensing of the first position sensor 501 and the second position sensor 502. Specifically, the first position sensor 501 and the second position sensor 502 can be selected as through-beam slot-type optocoupler photoelectric switch sensors.

[0043] As attached Figure 1 ~Appendix Figure 4 As shown, it also includes a baffle 3, which is disposed inside the chess box and located at the material discharge port 101.

[0044] The function of the baffle 3 is to prevent the chess pieces in the chessboard 1 from falling directly to the discharge port 101 without passing through the notch 201 of the rotor 2.

[0045] As attached Figure 1 ~Appendix Figure 4As shown, it also includes a first proximity switch 701 and a second proximity switch 702. Both the first proximity switch 701 and the second proximity switch 702 are disposed on the base 11, and the push rod 4 is located between the first proximity switch 701 and the second proximity switch 702.

[0046] Specifically, the first proximity switch 701 and the second proximity switch 702 are located at the two extreme positions of the push rod 4. When the push rod 4 touches the first proximity switch 701 or the second proximity switch 702, the motor 9 stops immediately.

[0047] As attached Figure 1 ~Appendix Figure 4 As shown, the one-way shaft 10 is perpendicular to the push rod 4.
