Description

Technical Field

[0001] This utility model relates to the field of Go piece processing technology, specifically a Go piece placement device. Background Technology

[0002] When firing Go stones, the Go blanks need to be arranged in a regular pattern first, and then the Go stones are fired. When arranging the stones, they are usually picked up manually or by vacuum suction cups and placed on the tray. This method of arrangement is inefficient. Therefore, by using a special Go blank arranging device, the Go blanks can be arranged quickly and evenly.

[0003] When in use, traditional chess-playing devices are inconvenient to pick up and place multiple chess pieces at once, resulting in low overall work efficiency.

[0004] To overcome the aforementioned shortcomings, existing technology (Chinese patent CN214526743U, published on 2021-10-29) describes a robotic arm for stacking Go board blanks. The gripper includes a connecting plate connected to a multi-axis robotic arm. The lower part of the connecting plate is connected to a suction cup assembly via multiple sets of telescopic mechanisms. The suction cup assembly includes a mounting base with multiple equally spaced airflow channels arranged along its length. These airflow channels penetrate one end face of the mounting base, and a vacuum connector is provided at that end. The lower part of the mounting base has multiple vacuum suction cups corresponding to each airflow channel. This allows for the simultaneous suction of multiple Go board blanks for transfer, resulting in higher efficiency compared to traditional manual picking. It also solves the problem of complex piping caused by each vacuum suction cup requiring a separate suction pipe, simplifying the overall design and reducing the need for future maintenance and replacement.

[0005] The aforementioned mechanism uses a vacuum system to adsorb and stack multiple chess pieces at once. However, most chess pieces need to be polished before firing, and there will be some debris residue on the surface of the chess pieces, which causes too much dust to enter the device during vacuum adsorption. Utility Model Content

[0006] The purpose of this utility model is to provide a chess piece placement device to solve the problem mentioned in the background art that traditional placement devices are inconvenient to pick up and place multiple chess pieces at one time, resulting in low overall work efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a chess piece arrangement device, comprising a conveying assembly, wherein gripping frames are provided on both sides of the conveying assembly, and a fixing frame is provided on the left side of the top of the conveying assembly;

[0008] The output end of the gripping frame is provided with a connecting plate, and a vacuum adsorption mechanism for adsorbing and gripping chess pieces is provided below the connecting plate. The vacuum adsorption mechanism includes an air bladder, which is located at the middle position of the bottom end of the connecting plate. Pneumatic telescopic rods are provided at both the front and rear ends of the bottom end of the connecting plate, and a fixing plate is installed at the output end of the pneumatic telescopic rod. A vacuum suction cup is provided at the bottom end of the fixing plate.

[0009] A servo motor is provided at the lower right side of the fixed frame, and the output end of the servo motor extends into the interior of the fixed frame and is equipped with a dust removal mechanism for surface dust removal of the chess pieces.

[0010] Furthermore, elastic telescopic rods are installed at the four corners of the top of the fixed plate, and the top of the elastic telescopic rods are connected to the four corners of the bottom of the connecting plate.

[0011] Furthermore, the vacuum suction cups are evenly distributed at the bottom end of the fixed plate, and the vacuum suction cups are symmetrical about the vertical central axis of the fixed plate.

[0012] Furthermore, the dust removal mechanism includes a threaded rod, which is rotatably connected to the upper end of one end of the fixed frame. A movable block is threadedly connected to the outer side of the threaded rod, and a fan is installed at the bottom end of the movable block.

[0013] Furthermore, a slider is provided at the top of the movable block, and a slide rail matching the slider is provided at the middle position of the top of the fixed frame. The movable block and the fixed frame are slidably connected by the slider and the slide rail to form a sliding mechanism.

[0014] Furthermore, the fixed frame is provided with a rotating rod inside, and an anti-stacking mechanism for moving the chess pieces is provided on the outside of the rotating rod. The anti-stacking mechanism includes a mounting box, and the mounting box is distributed at equal angles on the outside of the rotating rod. A scraper is installed inside the mounting box.

[0015] Furthermore, the top of the mounting box is threaded with bolts at equal intervals, and the bottom end of the bolts passes through the scraper and extends to the bottom of the mounting box.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The chess pieces are conveyed by the conveying component, and then the chess pieces are adsorbed and grabbed by the cooperation of the vacuum adsorption mechanism and the connecting plate. Then, the connecting plate is used to rotate the direction of the entire vacuum adsorption mechanism, and then the chess pieces are placed.

[0018] Furthermore, by setting multiple vacuum suction cups at the bottom of the fixed plate, the working efficiency is higher when grasping the chess piece. The air bag is controlled by moving the output end of the pneumatic telescopic rod up and down. When the pneumatic telescopic rod moves downward, the overall length of the air bag increases, so that the air bag is in the suction state, which in turn makes the inner side of the vacuum suction cup under the fixed plate a vacuum state, thereby realizing the grasping of the chess piece.

[0019] Furthermore, the output end of the pneumatic telescopic rod moves upward, causing the airbag to be in a compressed state, thereby blowing out the gas inside the airbag. This causes the chess pieces adsorbed below the vacuum suction cup to lose their adsorption force and fall down and be placed. The elastic telescopic rods set at the four corners of the fixed plate can make the up-and-down movement of the fixed plate more stable and avoid the overall angle of the fixed plate from shifting.

[0020] 2. The output end of the servo motor drives the threaded rod to rotate, which in turn drives the movable block to move left and right. The movable block drives the slider below to move left and right. The slider blows air to remove dust from the surface of the chess piece, so as to prevent the chess piece from being not firmly adsorbed due to dust during the subsequent vacuum adsorption.

[0021] Furthermore, the output of the servo motor can drive the rotating rod to rotate. When the rotating rod rotates, it will drive the mounting box and scraper to move the chess pieces being conveyed, so that the stacked chess pieces during the conveying process can be pushed to a position with gaps at the back. This avoids the situation where the chess pieces cannot be adsorbed due to stacking during the vacuum adsorption process. At the same time, the anti-stacking treatment of the chess pieces also makes the subsequent dust removal of the chess pieces more comprehensive, avoiding the situation where some chess pieces are blocked and the dust is not completely removed.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0030] like Figures 1-4 The technical solution shown addresses the problem of low overall work efficiency caused by the inconvenience of traditional chess piece placement devices in handling multiple pieces at once. This chess piece placement device discloses a vacuum adsorption mechanism, including a conveying component 1. Gripping frames 2 are provided on both sides of the conveying component 1, and a fixing frame 9 is provided on the left side of the top of the conveying component 1. A connecting plate 3 is provided at the output end of the gripping frame 2, and a vacuum adsorption mechanism for adsorbing and gripping the chess pieces is provided below the connecting plate 3. The vacuum adsorption mechanism includes an airbag 4, which is located at the middle of the bottom of the connecting plate 3. Pneumatic telescopic rods 5 are provided at both the front and rear ends of the bottom of the connecting plate 3, and a fixing plate 6 is installed at the output end of the pneumatic telescopic rods 5. A vacuum suction cup 7 is provided at the bottom of the fixing plate 6, and elastic telescopic rods 8 are installed at the four corners of the top of the fixing plate 6. The tops of the elastic telescopic rods 8 are connected to the four corners of the bottom of the connecting plate 3. The vacuum suction cups 7 are evenly distributed at the bottom of the fixing plate 6, and the vacuum suction cups 7 are symmetrical about the vertical central axis of the fixing plate 6.

[0031] In this example, the chess pieces are conveyed by the conveying component 1, and then the chess pieces are adsorbed and grasped by the cooperation of the vacuum adsorption mechanism and the connecting plate 3. Then, the connecting plate 3 is used to rotate the direction of the entire vacuum adsorption mechanism, and then the chess pieces are placed.

[0032] By setting multiple vacuum suction cups 7 at the bottom of the fixed plate 6, the working efficiency is higher when grasping the chess piece. The air bag 4 is controlled by moving up and down through the output end of the pneumatic telescopic rod 5. When the pneumatic telescopic rod 5 moves downward, the overall length of the air bag 4 increases, so that the air bag 4 is in the suction state, which in turn makes the inner side of the vacuum suction cup 7 under the fixed plate 6 a vacuum state, thereby realizing the grasping of the chess piece.

[0033] When the output end of the pneumatic telescopic rod 5 moves upward, the airbag 4 is compressed, which blows out the gas inside the airbag 4. This causes the chess piece adsorbed below the vacuum suction cup 7 to lose its adsorption force and fall down and be placed. The elastic telescopic rods 8 set at the four corners of the fixed plate 6 make the up-and-down movement of the fixed plate 6 more stable and avoid the overall angle of the fixed plate 6 from shifting. Example 2:

[0034] like Figure 1 , Figure 2 and Figure 5 The technical solution shown addresses the problem of dust residue on the surface of chess pieces while they are waiting to be stacked, leading to unstable vacuum adsorption. The chess piece arrangement device discloses a dust removal mechanism. A servo motor 10 is installed at the lower right side of the outer side of the fixed frame 9, and the output end of the servo motor 10 extends into the interior of the fixed frame 9, where a dust removal mechanism is installed for surface dust removal of the chess pieces. The dust removal mechanism includes a threaded rod 11, which is rotatably connected to the upper end of one end inside the fixed frame 9. A movable block 12 is threadedly connected to the outer side of the threaded rod 11, and a fan 13 is installed at the bottom end of the movable block 12. A slider 14 is installed at the top end of the movable block 12, and a slide rail 15 matching the slider 14 is provided at the middle position of the top end inside the fixed frame 9. The movable block 12 and the fixed frame 9 are slidably connected by the slider 14 and the slide rail 15 to form a sliding mechanism.

[0035] In this example, since the chess pieces need to be polished during the processing, there will be some dust residue on the surface of the chess pieces. The output end of the servo motor 10 drives the threaded rod 11 to rotate, so that the threaded rod 11 can drive the movable block 12 to move left and right. The movable block 12 drives the slider 14 below to move left and right. The slider 14 blows air to remove the dust on the surface of the chess pieces, so as to avoid the situation that the chess pieces are not firmly adsorbed due to dust when vacuum adsorption is performed later.

[0036] The slider 14 and slide rail 15 above the movable block 12 work together to make the movable block 12 move more smoothly, effectively preventing the movable block 12 from shifting at an angle when it is driven by the threaded rod 11, and increasing the smoothness of the whole operation. Example 3:

[0037] like Figure 1 , Figure 2 , Figure 5 and Figure 6The technical solution shown addresses the problem of chess pieces stacking during transport: the chess piece swaying device discloses an anti-stacking mechanism. A rotating rod 16 is installed inside the fixed frame 9, and an anti-stacking mechanism for moving the chess pieces is installed on the outside of the rotating rod 16. The anti-stacking mechanism includes a mounting box 17, which is distributed at equal angles on the outside of the rotating rod 16. A scraper 18 is installed inside the mounting box 17, and bolts 19 are threaded at equal intervals on the top of the mounting box 17. The bottom end of the bolts 19 passes through the scraper 18 and extends to the bottom of the mounting box 17.

[0038] In this example, the output of the servo motor 10 drives the rotating rod 16 to rotate. When the rotating rod 16 rotates, it drives the mounting box 17 and the scraper 18 to move the chess pieces being conveyed. This allows the stacked chess pieces during the conveying process to be pushed to a position with gaps at the back, avoiding the situation where the chess pieces cannot be adsorbed due to stacking during the vacuum adsorption process. At the same time, the anti-stacking treatment of the chess pieces also makes the subsequent dust removal of the chess pieces more comprehensive, avoiding the situation where some chess pieces are blocked and the dust is not completely removed.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
