Description

Technical Field

[0002] The Rubik's Cube is an educational toy that can achieve the specified face color splicing by rotating. It is usually made of plastic material. According to the different orders, it can be divided into two-order, three-order, four-order and multi-order Rubik's Cubes. Among them, the three-order Rubik's Cube is a cube, which is divided into the top layer, the middle layer and the bottom layer in each coordinate axis direction. Each layer can be rotated freely, and the position of the small cubes on the cube can be changed by rotating the layer. The main structure of the three-order Rubik's Cube generally includes a cross center axis with six connecting arms perpendicular to each other, six center blocks rotatably connected to the six connecting arms of the cross center axis, and 12 edge blocks and 8 corner blocks that are rotatably connected to the center block. In the production process of the Rubik's Cube, it is usually necessary to combine and assemble the Rubik's Cube layer by layer, thus often involving the assembly of the top layer and the bottom layer, wherein the corner blocks and edge blocks of some Rubik's Cubes are correspondingly spliced ​​by corner seats and edge seats of the required shape and size, and the edge blocks spliced ​​by two edge seats and the corner blocks spliced ​​by three corner seats are relatively small as a whole, and the corner seats and edge seats are not standard parts with regular shapes, and they need to be assembled at a certain assembly angle to achieve accurate alignment. Therefore, at present, manual labor is mostly used for the assembly of such corner blocks and edge blocks, which has low assembly efficiency and cannot effectively guarantee assembly accuracy. In addition, when the assembled corner blocks and edge blocks are transported to the existing equipment for assembling the top layer and the bottom layer, angle adjustment and positioning integration are required again, which prolongs the assembly time and reduces production efficiency.

[0003] Therefore, there is an urgent need for a Rubik's Cube single-layer assembly machine that can realize automated operation, has a simple structure, high assembly precision and high efficiency to overcome the above problems. Summary of the invention

[0024] In order to explain the content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0025] See also Figures 1 to 3 The present invention discloses a Rubik's Cube single-layer assembly machine 100, which is suitable for assembling the top layer 200 and the bottom layer of the Rubik's Cube. In the present application, the Rubik's Cube is a three-order Rubik's Cube, and its top layer 200 and the bottom layer are both composed of a center block (not shown in the figure) and four edge blocks 300 and four corner blocks 400 located on the circumference thereof. The center block is used to connect with the Rubik's Cube cross center component, and the edge blocks 300 and the corner blocks 400 are arranged at intervals in the circumferential direction of the center block, that is, one edge block 300 is spliced ​​between each two adjacent corner blocks 400. Among them, the edge block 300 is formed by two identical prism seats 301 inserted into each other through a concave-convex matching plug-in structure. Specifically, the opposite sides of the plug-in end of each prism seat 301 are respectively provided with matching plug holes and plug rods, so that they can be plugged into the plug rods and plug holes of the plug-in end of another prism seat 301 to form an edge block 300, and the assembled edge block 300 is a cubic block with a clamping portion 300a. The corner block 400 is formed by three identical corner seats 401 plugged in pairs from three directions through a concave-convex plug-in structure. Specifically, the opposite sides of the plug-in end of each corner seat 401 are provided with matching sockets and plug-in plates, so that they can be plugged into the plug-in plates and sockets of the two corner seats 401 on both sides thereof to form a corner block 400, and the assembled corner block 400 is a cubic block with a clamping portion 400a.

[0026] See also Figures 1 to 3 The Rubik's Cube single-layer assembly machine 100 provided in the preferred embodiment of the present invention includes an assembly unit 10 and two splicing units 20 arranged on two opposite sides of the assembly unit 10, each splicing unit 20 includes an edge block assembly device 30, two corner block assembly devices 40 and a first splicing device 50 located between the edge block assembly device 30 and the two corner block assembly devices 40, and the assembly unit 10 includes two edge block assembly devices 30 and a second splicing device 60 located between the two edge block assembly devices 30. The edge block assembly device 30 is used to assemble two edge seats 301 into an edge block 300, the corner block assembly device 40 is used to assemble three corner seats 401 into a corner block 400, the first splicing device 50 is used to splice an edge block 300 between two corner blocks 400 to form a splicing piece 201, and the second splicing device 60 is used to splice two edge blocks 300 provided by the two edge block assembly devices 30 arranged on both sides thereof between two splicing pieces 201 provided by the two first splicing devices 50, thereby forming a top layer 200 or a bottom layer of the Rubik's Cube.

[0027] It should be noted that the Rubik's Cube single-layer assembly machine 100 of the present invention is mainly used for splicing the edge blocks 300 and corner blocks 400 of the top layer 200 or the bottom layer of the Rubik's Cube, while the assembly of the center blocks located at the center of the corresponding top layer 200 or bottom layer is completed in other devices. That is, after the top layer 200 or the bottom layer is assembled to the middle layer with a cross center component, the center blocks are assembled correspondingly. Of course, the Rubik's Cube single-layer assembly machine 100 of the present invention also includes a control system, which is electrically connected to the edge block assembly device 30, the corner block assembly device 40, the first splicing device 50 and the second splicing device 60, and is used to control the coordinated actions between the devices. Among them, the control system is an existing design, and its structure and control principle are well known in the art, so it will not be described in detail here.

[0028] In addition, in the present application, since there is a certain directionality in the assembly of the corresponding engaging portions 300a and 400a when the edge block 300 and the corner block 400 are spliced, in order to achieve efficient assembly, in this embodiment, the second splicing device 60 can first splice the two edge blocks 300 with the splicing member 201 on one side, and then splice the splicing member 201 on the other side to the two edge blocks 300, so that the assembly process is smoother. Of course, in other embodiments, the two splicing members 201 can also be butted simultaneously in the direction of approaching the two edge blocks 300 on both sides of the two edge blocks 300, and the assembly of the required top layer 200 or bottom layer can also be achieved. At this time, it is necessary to first position the two edge blocks 300, and the positioning of the two edge blocks 300 is relatively more complicated than the positioning of the splicing member 201.

[0029] Refer to Figure 2 and Figure 3 , in the preferred embodiment of the present invention, the edge block assembly device 30 and the two corner block assembly devices 40 on the periphery of the first splicing device 50 are arranged in a "pin" shape, the two edge block assembly devices 30 on both sides of the second splicing device 60 are arranged in a "one" shape, and the two first splicing devices 50 and one second splicing device 60 are arranged in a "Z" shape, so as to optimize the structure, facilitate the accurate docking of the edge seats 301, the corner seats 401, between one edge block 300 and two corner blocks 400, and between the two splicing members 201 and the two corner blocks 400, and make the overall structure of the machine more compact, effectively shortening the moving stroke between the devices, and thus improving the assembly efficiency.

[0030] Combined with Figure 3 and Figure 4The edge block assembly device 30 includes two edge seat vibration material plates 32 arranged in parallel and at intervals on the base 31 and two first profiling jigs 33 arranged at the discharge ports 321 of the two edge seat vibration material plates 32. The ends of the first profiling jigs 33 have a receiving groove 331 that matches the shape of the outer contour of the edge seat 301. The receiving groove 331 is provided with a vacuum suction cup for fixing the edge seat 301 (not shown in the figure due to obstruction). The two first profiling jigs 33 can make a linear reciprocating motion to move closer to or away from each other, and correspondingly push the two edge seats 301 received by the two discharge ports 321 to be close to each other for insertion, thereby forming an edge block 300. Specifically, two first profiling jigs 33 are mounted on the base 31 through a carrier 34, and the carrier 34 is provided with two linear guide rails 35 arranged in a direction perpendicular to the feeding direction of the prism seat vibrating plate 32. The two first profiling jigs 33 are correspondingly slid on the two linear guide rails 35 and are connected to two linear drivers 36 one by one. The two linear drivers 36 correspondingly drive the first profiling jigs 33 connected thereto to slide on the corresponding linear guide rails 35, so that the two first profiling jigs 33 push the two prism seats 301 received at the two discharge ports 321 toward each other to the docking station for docking, wherein the docking station is located at the center of the two discharge ports 321.

[0031] Preferably, the prism assembly device 30 further includes two blocking members 37 disposed on the carrier 34, which are arranged one by one on the sides of the two first profiling jigs 33 and can make a linear reciprocating motion close to or away from the first profiling jig 33 to prevent the prism seat 301 from accidentally falling off from the end of the first profiling jig 33, such as when the vacuum suction cup is not firmly adsorbed. Specifically, the blocking member 37 can make a linear reciprocating motion close to or away from the first profiling jig 33 under the drive of the blocking driver 38 connected thereto, so as to abut against the prism seat 301 from the outside of the first profiling jig 33 to prevent it from accidentally falling off, and can also play a certain role in alignment adjustment.

[0032] Combination Figure 3 and Figure 5The corner block assembly device 40 includes three corner seat vibration material discs 42 arranged at intervals of 120° on a base 41 and three second profiling jigs 43 arranged one by one at the outlets 421 corresponding to the three corner seat vibration material discs 42. The end of the second profiling jig 43 has a receiving groove 431 that matches the shape of the outer contour of the corner seat 401. The receiving groove 431 is provided with a vacuum suction cup for fixing the corner seat 401 (not shown in the figure due to obstruction). The three second profiling jigs 43 can make linear movements to move closer to or away from each other, and correspondingly push the three corner seats 401 received by the three outlets 421 to be close to each other for insertion, thereby forming a corner block 400. Specifically, three second profiling jigs 43 are mounted on the base 41 through a carrier 44, and the carrier 44 is provided with three linear guide rails 45 arranged in a direction perpendicular to the feeding direction of the corner seat vibrating plate 42. The three second profiling jigs 43 are slidably mounted on the three linear guide rails 45 one by one, and are connected to three linear drivers 46 one by one. The three linear drivers 46 drive the second profiling jigs 43 connected thereto to slide on the corresponding linear guide rails 45, so that the three second profiling jigs 43 push the three corner seats 401 received at the three discharge ports 421 to the docking station from three directions at the same time for docking, wherein the docking station is located at the center of the three discharge ports 421.

[0033] Preferably, the corner block assembly device 40 further includes three blocking members 47 disposed on the carrier 44, and the three second blocking members 47 are arranged one by one on the sides of the three second profiling jigs 43, and can be moved back and forth linearly close to or away from the second profiling jigs 43, so as to prevent the corner seat 401 from being separated from the three second profiling jigs 43. Specifically, the blocking member 47 can be driven by a blocking driver 48 connected thereto to move back and forth linearly close to or away from the second profiling jig 43, so as to abut against the corner seat 401 from the outside of the second profiling jig 43, so as to prevent it from accidentally falling off, and can also play a certain role in alignment adjustment.

The first conveyor belt 52 and the two second conveyor belts 53 cooperate with each other, and can splice two corner blocks 400 and an edge block 300 into one at the output ends of the three, thereby forming a splicing piece 201 in which the edge block 300 is in the center and the two corner blocks 400 are located on both sides of the edge block 300.

[0035] Specifically, the first conveyor belt 52 is connected between the base 31 and the first splicing platform 51, and the second conveyor belt 53 is connected between the base 41 and the first splicing platform 51.

Similarly, the corner block 400 assembled at the corner block assembly device 40 can be directly dropped from the docking station on the carrier 44 to the second conveyor belt 53 provided on the base 41 for transportation, or it can be moved from the docking station to the second conveyor belt 53 for transportation by a corner block robot, or it can be moved or rotated to the second conveyor belt 53 for transportation by a movable part or rotating part supported under the corner block 400.

[0036] Preferably, the first conveyor belt 52 and the second conveyor belt 53 are provided with a limit plate 54 along their respective conveying directions, and a limit plate 54 is provided on each of the two opposite sides of the first conveyor belt 52, so that the conveying direction of the edge block 300 is limited by the two limit plates 54 to prevent it from deviating, so as to improve the accuracy of subsequent splicing. Correspondingly, the two limit plates 54 provided on the two opposite sides of the second conveyor belt 53 are used to limit the conveying direction of the corner block 400, so that it can maintain the required splicing angle as much as possible during the conveying process.

The two second guide grooves 56 can receive the corresponding corner blocks 400 conveyed by the two second conveyor belts 53 from two parallel directions. The first guide groove 55 is used to receive the edge blocks 300 conveyed by the first conveyor belt 52. The splicing drive member 57 at the first guide groove 55 is used to accurately align and push the edge blocks 300 to the first splicing position 50a. The two splicing drive members 57 at the two second guide grooves 56 are used to accurately align and push the two corner blocks 400 to the first splicing position 50a, thereby splicing the three into a splicing piece 201.

[0047] After the equipment is started, under the instruction of the control system, the two corner block assembly devices 40 of each splicing unit 20 respectively assemble the three corner seats 401 into a corner block 400, and at the same time, the edge block assembly device 30 of each splicing unit 20 correspondingly assembles the two edge seats 301 into an edge block 300, and then the first splicing device 50 on the corresponding side splices an edge block 300 between the two corner blocks 400 to form a spliced ​​piece 201; then, the third conveyor belt 62 and the fourth conveyor belt 63 of the second splicing device 60 correspondingly convey the two spliced ​​pieces 201 spliced ​​at the two first splicing devices 50 toward the second splicing station 61, and at the same time, the two edge block assembly devices 30 in the assembly unit 10 respectively assemble the two edge seats 301 into an edge block 300, and the two edge blocks of the second splicing device 60 are connected to the second splicing station 61. The fifth conveyor belt 64 then conveys the two edge blocks 300 in the direction of the second splicing station 61; wherein, a splicing piece 201 on the third conveyor belt 62 is first conveyed to the second splicing position 60a, and the two edge blocks 300 on the two fifth conveyor belts 64 are then conveyed to the second splicing position 60a in opposite directions, thereby being pushed to be spliced ​​on the splicing piece 201; thereafter, another splicing piece 201 on the fourth conveyor belt 63 is pushed to the two edge blocks 300 spliced ​​at the second splicing position 60a, thereby forming the top layer 200 or bottom layer of the magic cube; finally, the third conveyor belt 62 conveys the spliced ​​top layer 200 or bottom layer of the magic cube to the sixth conveyor belt 71, and then the transfer mechanism 72 moves the top layer 200 or bottom layer of the magic cube conveyed by the sixth conveyor belt 71 out of the machine for unloading;

[0048] By repeating the above operations continuously, the automated assembly line operation of assembling the top layer 200 or the bottom layer of the Rubik's Cube can be realized.

[0049] Compared with the prior art, the Rubik's Cube single-layer assembly machine 100 of the present invention includes an assembly unit 10 and two splicing units 20 arranged on two opposite sides thereof. The two corner block assembly devices 40 of the splicing unit 20 each assemble three corner seats 401 into a corner block 400, and the edge block assembly device 30 of the splicing unit 20 can simultaneously assemble two edge seats 301 into an edge block 300, and then the first splicing device 50 splices the edge block 300 between the two corner blocks 400 to form a splicing piece 201; the two edge block assembly devices 30 in the assembly unit 10 each assemble two edge seats 301 into an edge block 300, and also splices the two edge blocks 300 provided by the two edge block assembly devices 30 arranged on both sides thereof between the two splicing pieces 201 provided by the two first splicing devices 50 through the second splicing device 60, thereby forming the top layer 200 or bottom layer of the Rubik's Cube. The Rubik's Cube single-layer assembly machine 100 of the present invention has a simple structure, a reasonable and compact layout, and can realize the automated assembly line operation of the top layer 200 and the bottom layer of the Rubik's Cube, thereby effectively improving the assembly efficiency and assembly accuracy.
