Description

Technical Field

[0001] This utility model relates to the field of mahjong machine manufacturing technology, and in particular to an integrated base plate gripping device for mahjong machines. Background Technology

[0002] A mahjong machine is an automated device specifically designed for mahjong games. Its core function is to replace manual labor in shuffling, arranging, and stacking the tiles, significantly improving game efficiency and convenience. It typically consists of a main unit mounted on an integrated base plate, a shuffling drum, a conveyor mechanism, a stacking device, and a lifting plate. During operation, a built-in motor and program control automatically sort and stack the shuffled mahjong tiles into standard rows. Finally, the lifting plate smoothly delivers the tiles to the table, all without manual intervention.

[0003] In the automated production process of mahjong machines, integrated base plates are often stored in multiple stacks, and subsequently transferred by a robotic arm-controlled gripping device. These integrated base plates are mostly U-shaped structures, but most current mainstream gripping devices only apply force from one direction, either the inside or the outside, to grasp them. This unilateral gripping method easily leads to an imbalance of force on the integrated base plate during the gripping process, resulting in deformation problems. Utility Model Content

[0004] To solve the above problems, this utility model provides an integrated base plate gripping device for mahjong machines.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mahjong machine integrated base plate gripping device, including a connecting frame for connecting with a robotic arm, a mounting plate is provided at the bottom of the connecting frame, four circumferentially arrayed strip holes are provided on the mounting plate, a first sliding block and a second sliding block are slidably arranged in the strip holes, the bottom of the first sliding block and the second sliding block extend downward and are respectively provided with a first support plate and a second support plate, the top of the first sliding block and the second sliding block are respectively provided with a first adjusting column and a second adjusting column, an adjusting disk is rotatably arranged in the middle of the top surface of the mounting plate, a driving component for driving the adjusting disk to rotate is provided on the connecting frame, an arc-shaped through hole is provided through the top of the adjusting disk and slidably connected to the first adjusting column, an adjusting rod is rotatably arranged on the second adjusting column, and the end of the adjusting rod away from the second adjusting column is hinged to the side of the adjusting disk.

[0006] By adopting the above technical solution, a connecting frame, mounting plate, and adjusting plate are set up. When the adjusting plate rotates under the drive of the drive component, the arc-shaped through hole on the adjusting plate moves together with the adjusting plate. Since the arc-shaped through hole is slidably connected to the first adjusting column, the movement of the arc-shaped through hole will generate an outward pushing force on the first adjusting column, thereby pushing the first sliding block to slide in the strip hole in an outward direction. The first support plate moves outward synchronously with the first sliding block. At the same time, the rotation of the adjusting plate will also drive the adjusting rod hinged to it to move. The adjusting rod will apply an inward pulling force to the second adjusting column, causing the second sliding block to slide in the strip hole in an inward direction. The second support plate moves inward synchronously with the second sliding block. This can achieve simultaneous support and lifting of the inner and outer sides of the U-shaped integrated base plate, effectively dispersing the force on the integrated base plate, avoiding deformation of the U-shaped integrated base plate due to uneven force during the gripping process, ensuring the structural integrity of the integrated base plate, and improving the stability and reliability of the gripping device for the U-shaped integrated base plate.

[0007] Furthermore, the first tray extends from the first sliding block toward the second sliding block, and the second tray extends from the second sliding block toward the first sliding block.

[0008] By adopting the above technical solution, the first support plate extends from the first sliding block to the second sliding block, and the second support plate extends from the second sliding block to the first sliding block, ensuring the stability of the integrated base plate.

[0009] Furthermore, the axis of the arc-shaped through hole is eccentrically set with respect to the axis of the adjusting disc, and the number of the arc-shaped through holes is equal to the number of the first adjusting columns, with their positions corresponding one-to-one.

[0010] By adopting the above technical solution, each first adjusting column can be driven by an independent arc-shaped through hole, ensuring the synchronicity and consistency of the movement of multiple first adjusting columns, thereby ensuring that multiple first sliding blocks and first support plates can move outward simultaneously and uniformly.

[0011] Furthermore, four hinge seats are circumferentially spaced on the outer side of the adjusting disc, and a hinge shaft is provided on each hinge seat. The end of the adjusting rod away from the second adjusting column is rotatably connected to the hinge shaft.

[0012] By adopting the above technical solution, the hinge seat and hinge shaft provide a stable and flexible rotation fulcrum for the connection between the adjusting rod and the adjusting disc, ensuring that the adjusting disc can smoothly drive the adjusting rod to move when it rotates, and reducing the wear of the connection between the adjusting rod and the adjusting disc.

[0013] Furthermore, the end of the arc-shaped through hole near the center of the adjustment disk is located between the hinge seat and the center of the adjustment disk.

[0014] By adopting the above technical solution, the setting of the arc-shaped through hole and the hinge seat position can form a more reasonable positional relationship between the movement trajectory of the first adjusting column in the arc-shaped through hole and the movement trajectory of the second adjusting column driven by the adjusting rod during the rotation of the adjusting plate, so as to ensure that the first pallet moves outward and the second pallet moves inward.

[0015] Furthermore, the connecting frame includes a connecting seat and four connecting columns arranged in a rectangular array at the bottom of the connecting seat. The mounting plate is connected to the lower ends of the four connecting columns. The driving assembly includes a fixing plate connected to the four connecting columns. A driving motor is provided on the fixing plate. The output shaft of the driving motor passes through the fixing plate and is connected to the adjusting plate.

[0016] By adopting the above technical solution, the support of the four connecting columns on the mounting plate is more even, ensuring the stability of the mounting plate during operation. The drive motor drives the adjusting disc to rotate.

[0017] Furthermore, a sliding rod is provided inside the strip-shaped hole, and the length direction of the sliding rod is consistent with the length direction of the strip-shaped hole. Sliding holes are respectively opened on the first sliding block and the second sliding block to slide and connect with the sliding rod.

[0018] By adopting the above technical solution, the slide bar can guide the sliding of the first and second sliding blocks, further ensuring the linearity and smoothness of their movement. Simultaneously, the slide bar can also provide some support for the first and second sliding blocks, enhancing their stability during the sliding process.

[0019] Furthermore, the mounting plate is generally cross-shaped.

[0020] In summary, this utility model has the following beneficial effects: In this application, a connecting frame, a mounting plate, and an adjusting plate are provided. When the adjusting plate rotates under the drive of the driving component, the arc-shaped through hole on the adjusting plate moves along with the adjusting plate. Since the arc-shaped through hole is slidably connected to the first adjusting column, the movement of the arc-shaped through hole generates an outward pushing force on the first adjusting column, thereby pushing the first sliding block to slide outward in the strip hole. The first support plate moves outward synchronously with the first sliding block. Simultaneously, the rotation of the adjusting plate also drives the adjusting rod hinged to it to move. The adjusting rod applies an inward pulling force to the second adjusting column, causing the second sliding block to slide inward in the strip hole. The second support plate moves inward synchronously with the second sliding block. This enables simultaneous support and lifting of both the inner and outer sides of the U-shaped integrated base plate, effectively dispersing the force on the integrated base plate, preventing deformation of the U-shaped integrated base plate due to uneven force during gripping, ensuring the structural integrity of the integrated base plate, and improving the stability and reliability of the gripping device in gripping the U-shaped integrated base plate.

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] like Figure 1-4As shown in the figure, this application discloses an integrated base plate gripping device for a mahjong machine, including a connecting frame 10, a mounting plate 20, and a drive assembly 60. The connecting frame 10 is used to connect with a robotic arm. The mounting plate 20 is disposed at the bottom of the connecting frame 10, and has four circumferentially arranged strip holes 21. The four strip holes 21 are generally cross-shaped. A first sliding block 30 and a second sliding block 40 are slidably disposed in the strip holes 21. The bottom of the first sliding block 30 and the second sliding block 40 extends downward and is respectively provided with a first support plate 31 and a second support plate 41. The first support plate 31 and the second support plate 41 are used to lift the integrated base plate. The top of the first sliding block 30 and the second sliding block 40 are respectively vertically provided with a first adjusting column 32 and a second adjusting column 42. An adjusting disk 50 is rotatably disposed in the middle of the top surface of the mounting plate 20. The drive assembly 60 is disposed on the connecting frame 10 and is used to drive the adjusting disk 50 to rotate. The top of the adjusting disk 50 has a through-hole 51 that is slidably connected to the first adjusting post 32. An adjusting rod 43 is rotatably mounted on the second adjusting post 42, and the end of the adjusting rod 43 away from the second adjusting post 42 is hinged to the side of the adjusting disk 50. When the adjusting disk 50 rotates under the drive of the driving assembly 60, the through-hole 51 on the adjusting disk 50 moves with the adjusting disk 50. Since the through-hole 51 is slidably connected to the first adjusting post 32, the movement of the through-hole 51 will generate an outward pushing force on the first adjusting post 32, thereby pushing the first sliding block 30 to slide outward in the strip hole 21. The first support plate 31 moves outward synchronously with the first sliding block 30. Simultaneously, the rotation of the adjusting disc 50 also drives the adjusting rod 43, which is hinged to it, to move. The adjusting rod 43 applies an inward pulling force to the second adjusting column 42, causing the second sliding block 40 to slide inward within the strip hole 21. The second support plate 41 moves inward synchronously with the second sliding block 40. This allows for simultaneous support and lifting of both the inner and outer sides of the U-shaped integrated base plate, effectively dispersing the force on the integrated base plate, preventing deformation due to uneven force during gripping, ensuring the structural integrity of the integrated base plate, and improving the stability and reliability of the gripping device in gripping the U-shaped integrated base plate.

[0025] Specifically, the mounting plate 20 is cross-shaped, which effectively reduces its overall weight and the load on the gripping device while ensuring its structural strength. It also facilitates the creation of four circumferentially arranged strip-shaped holes 21 on the mounting plate 20, providing reasonable space for the installation and sliding of the first sliding block 30 and the second sliding block 40. The connecting frame 10 includes a connecting base 11 and four connecting posts 12 arranged in a rectangular array at the bottom of the connecting base 11. The mounting plate 20 is connected to the lower ends of the four connecting posts 12. The drive assembly 60 includes a fixed plate 61 connected to the four connecting posts 12. A rotating column is rotatably mounted on the mounting plate 20, and an adjusting disk 50 is connected to the rotating column. A drive motor 62 is mounted on the fixed plate 61, and the output shaft of the drive motor 62 passes through the fixed plate 61 and connects to the adjusting disk 50. The four connecting posts 12 provide more even support for the mounting plate 20, ensuring its stability during operation. The drive motor 62 drives the adjusting disk 50 to rotate.

[0026] During setup, the axis of the arc-shaped through hole 51 is eccentrically positioned with respect to the axis of the adjusting disk 50. The number of arc-shaped through holes 51 is equal to the number of first adjusting columns 32, and their positions correspond one-to-one. This ensures that each first adjusting column 32 can be driven by an independent arc-shaped through hole 51, guaranteeing the synchronicity and consistency of the movement of multiple first adjusting columns 32. Consequently, this ensures that multiple first sliding blocks 30 and first support plates 31 can move outward simultaneously and uniformly. Four hinge seats 52 are spaced circumferentially on the outer side of the adjusting disk 50. Each hinge seat 52 has a hinge shaft 53, and the end of the adjusting rod 43 furthest from the second adjusting column 42 is rotatably connected to the hinge shaft 53. The hinge seats 52 and hinge shaft 53 provide a stable and flexible rotation fulcrum for the connection between the adjusting rod 43 and the adjusting disk 50, ensuring that the adjusting disk 50 can smoothly drive the adjusting rod 43 when rotating, reducing wear on the connection between the adjusting rod 43 and the adjusting disk 50. Meanwhile, the four circumferentially spaced hinge seats 52 ensure that the four adjusting rods 43 are evenly distributed on the outside of the adjusting disk 50, guaranteeing a uniform driving force on the four second adjusting columns 42 when the adjusting disk 50 rotates. This allows the four second sliding blocks 40 and the second support plate 41 to move inward synchronously, achieving uniform support and lifting of the inner side of the U-shaped integrated base plate, further improving the stability and reliability of gripping the integrated base plate. The end of the arc-shaped through hole 51 near the center of the adjusting disk 50 is located between the hinge seat 52 and the center of the adjusting disk 50. The positioning of the arc-shaped through hole 51 and the hinge seat 52 allows for a more reasonable positional relationship between the movement trajectory of the first adjusting column 32 within the arc-shaped through hole 51 and the movement trajectory of the second adjusting column 42 driven by the adjusting rod 43 during the rotation of the adjusting disk 50. This ensures that the first support plate 31 moves outward and the second support plate 41 moves inward, guaranteeing stable and reliable support and lifting of both the inner and outer sides of the U-shaped integrated base plate, further improving the operational stability of the gripping device.

[0027] In a specific configuration, a sliding rod 22 is installed within the strip-shaped hole 21, with the length of the sliding rod 22 aligned with the length of the strip-shaped hole 21. Sliding holes are respectively provided on the first sliding block 30 and the second sliding block 40 to slidably connect with the sliding rod 22. The sliding rod 22 provides guidance for the sliding of the first sliding block 30 and the second sliding block 40, further ensuring the linearity and smoothness of their movement. Simultaneously, the sliding rod 22 also provides some support for the first sliding block 30 and the second sliding block 40, enhancing their stability during the sliding process. The first support plate 31 extends from the first sliding block 30 towards the second sliding block 40, and the second support plate 41 extends from the second sliding block 40 towards the first sliding block 30. This extension of the first support plate 31 and the second support plate 41 ensures stable support of the integrated base plate.

[0028] The operating principle of the integrated base plate gripping device for a mahjong machine in this embodiment is as follows: The connecting seat 11 is connected to the robotic arm, which drives the integrated base plate gripping device to move above and align with the integrated base plate. Then, the drive motor 62 starts, driving the adjusting disc 50 to rotate. The adjusting disc 50, on one hand, pushes the first adjusting column 32 through the arc-shaped through hole 51, causing the first sliding block 30 and the bottom first support plate 31 to slide outward along the strip hole 21 to support the inner side of the integrated base plate. On the other hand, it pulls the second adjusting column 42 through the hinge seat 52 and the adjusting rod 43, causing the second sliding block 40 and the bottom second support plate 41 to slide inward along the strip hole 21 to support the outer side of the integrated base plate, achieving synchronous support on both the inner and outer sides. Finally, the robotic arm drives the device to transfer the integrated base plate. After completion, the drive motor 62 rotates in the opposite direction to reset all components, ready for the next gripping operation.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
