Description

Technical Field

[0001] The present invention relates to the technical field of building block assembly, in particular to an automatic building block assembly machine. Background Art

[0002] Building blocks are typically cubes of wood or plastic that can be arranged and combined to create various houses, animal models, and other structures, helping to develop children's intelligence. Magnetic building blocks are a new type of building block, typically cubes, with magnets embedded within. Compared to traditional building blocks, magnetic building blocks offer more flexible play and are easier for young children to assemble because they connect magnetically.

[0003] Chinese invention patent publication number CN117226471B discloses a fully automatic multifunctional building block assembly machine comprising a frame, two fixed rods fixedly mounted on the top of the frame, a long plate fixedly mounted on the top of the two fixed rods, a lifting plate slidingly mounted on the two fixed rods, two second cylinders fixedly mounted on the top of the long plate, the telescopic ends of the two second cylinders being fixed to the connecting lifting plate, an assembly rod fixedly mounted on the bottom of the lifting plate, and a discharge hole formed in the top of the frame directly below the assembly rod. The machine can automatically load building blocks, load magnets, secure the building blocks, press-fit the building blocks and magnets, release the securement of the building blocks, and collect the unloaded building blocks after assembly, integrating multiple functions into one machine, achieving a high degree of automation and enabling continuous assembly of building blocks, thereby improving work efficiency.

[0004] However, the above-mentioned technical solution can only attach one magnet to a building block at a time, meaning the magnet is attached to the center of the building block. For larger building blocks, this method of assembly can make it difficult to securely attach the two building blocks together due to the large spacing between the magnets. To address this problem, embedding magnets on all six sides of the building block is often used. However, this also increases the assembly workload. Using the above-mentioned patented solution requires not only multiple assembly steps but also multiple flipping of the building blocks, which is inefficient. Summary of the Invention

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0058] See also Figure 1-15 The present invention describes the above technical solution in detail through the following embodiments:

[0059] An automatic building block assembly machine, comprising:

[0060] A building block conveying pipe 1 is used to convey building blocks. Vertical holes 2 are provided at the top and bottom of the building block conveying pipe 1.

[0061] Initial assembly mechanisms 3, two initial assembly mechanisms 3 are respectively arranged at the top and bottom of the building block conveying pipe 1, and the initial assembly mechanisms 3 are used to pass the magnets through the vertical holes 2 and embed them into the building blocks;

[0062] The secondary assembly box 4 has a transfer channel 401 and an assembly cavity 402 located above the transfer channel 401. The transfer channel 401 is connected to the building block conveying pipe 1. The box walls around the assembly cavity 402 are penetrated by transverse holes 5.

[0063] The supporting plate 6 is vertically slidably disposed in the secondary assembly box 4 and receives the building blocks conveyed from the building block conveying pipe 1 in the transfer channel 401;

[0064] A lifting mechanism 7 connected to the supporting plate 6 drives the supporting plate 6 to move up and down, so that the building blocks on the supporting plate 6 move back and forth between the transfer channel 401 and the assembly cavity 402;

[0065] Secondary assembly mechanism 8, four secondary assembly mechanisms 8 are respectively arranged on the outer walls around the assembly cavity 402, and the secondary assembly mechanism 8 is used to pass the magnet through the transverse hole 5 and embed it into the building block.

[0066] Specifically, when the building blocks transported in the building block conveying pipe 1 reach the vertical holes 2, the primary assembly mechanisms 3 at the top and bottom respectively insert two magnets through the corresponding vertical holes 2 and embed them into the two embedding holes at the top and bottom of the building blocks, thereby assembling the magnets at the top and bottom of the building blocks. Subsequently, the building blocks after the primary assembly are transported to the supporting plate 6. The lifting mechanism 7 drives the supporting plate 6 to rise, so that the building blocks on the supporting plate 6 enter the assembly cavity 402. At this time, the embedding holes around the building blocks are aligned with the transverse holes 5 around the assembly cavity 402. At this time, the secondary assembly mechanisms 8 on all sides synchronously insert four magnets through the corresponding transverse holes 5 and embed them into the corresponding embedding holes of the building blocks, thereby assembling the building blocks. After the assembly is completed, the lifting mechanism 7 drives the supporting plate 6 to reset downward to prepare for the unloading and loading of the building blocks.

[0067] The present invention uses two primary assembly mechanisms 3 on the building block conveying pipe 1 to assemble magnets on the top and bottom of the building block. After the primary assembly is completed, the building block arrives on the supporting plate 6, and the lifting mechanism 7 drives the supporting plate 6 to rise, so that the building block arrives in the assembly cavity 402, and uses four secondary assembly mechanisms 8 around the assembly cavity 402 to respectively install magnets on all sides of the building block. During the process, there is no need to turn the building block over. The assembly action is simple and efficient, thereby achieving efficient installation of magnets on the six sides of the building block.

[0068] Preferably, the front end of the transfer channel 401 is provided with a feed port connecting the transfer channel 401 and the building block conveying pipe 1, and the rear end of the building block conveying pipe 1 is provided with a discharge port connecting the transfer channel 401, and the feed port and the discharge port are located on the same straight line, so that the building blocks can be supplied to the supporting plate 6 while the building blocks that have been assembled and returned to the transfer channel 401 are pushed away from the supporting plate 6, or most of the building blocks are detached from the supporting plate 6. Subsequently, as the supporting plate 6 rises, the assembled building blocks that have not been completely separated from the supporting plate 6 will roll toward the discharge port.

[0069] The box walls around the assembly cavity 402 are all provided with clearance holes 9, and the box walls around the assembly cavity 402 are all provided with positioning claws 10 and limiting plates 11. The upper ends of the positioning claws 10 are hinged to the box walls of the assembly cavity 402. The limiting plates 11 are used to limit the positioning claws 10 in the initial position to a state where the lower ends are tilted inwards. The lower ends of the positioning claws 10 are located above the supporting plate 6.

[0070] When the lifting mechanism 7 drives the supporting plate 6 to rise, the supporting plate 6 pushes the lower ends of the positioning claws 10 on all sides to rotate inward synchronously, so that the building blocks on the supporting plate 6 are clamped and positioned by the positioning claws 10 on all sides, thereby ensuring that the embedding holes around the building blocks in the assembly cavity 402 can be aligned with the surrounding transverse holes 5.

[0071] In addition, the use of the positioning claws 10 on all sides to clamp and position the building blocks also avoids errors in the horizontal assembly coordination on all sides, that is, when the four secondary assembly mechanisms 8 fail to embed the magnets at the same time, it avoids the situation where the building blocks move during the magnet assembly process and the assembly cannot be completed.

[0072] Since the above embodiment cannot continue to rise after the building blocks are clamped and positioned by the positioning claws 10 on all sides, and is therefore only applicable to building blocks of a single size, the above embodiment is optimized as follows:

[0073] The size of the supporting plate 6 is adapted to the size of the assembly cavity 402. A guide cover 12 is provided on the outer walls around the assembly cavity 402. A slider 13 is provided vertically slidingly inside the guide cover 12. The upper end of the positioning claw 10 is hinged to the lower end of the slider 13, and the upper end of the limit plate 11 is connected to the slider 13. The positioning claw 10 and the limit plate 11 are both connected to the box wall of the assembly cavity 402 through the slider 13. A spring 14 for applying elastic force downward to the slider 13 is provided in the guide cover 12.

[0074] In this optimized embodiment, after the positioning claws 10 on all sides clamp and position the building blocks, the support plate 6 can push the slider 13 upward with the help of the positioning claws 10, thereby further driving the building blocks to rise, and the support plate 6 can slide up and down in the assembly cavity 402 to adapt to the assembly needs of building blocks of various sizes.

[0075] Among them, the function of the spring 14 is to prevent the positioning claw 10 from moving upward before clamping and positioning the building block. That is, the existence of the spring 14 enables the positioning claw 10 to act on the vertical transmission component between the supporting plate 6 and the slider 13 after the supporting plate 6 pushes the positioning claw 10 to clamp and position the building block, and pushes the slider 13 to move upward as the supporting plate 6 rises.

[0076] In the above-mentioned optimized embodiment, since the lower end of the positioning claw 10 needs to extend into the assembly cavity 402 when it is in the initial position, sufficient space needs to be reserved between the side of the building block and the inner side of the lower end of the positioning claw 10 on the same side. On the one hand, it is beneficial for the positioning claw 10 to exert force on the supporting plate 6. On the other hand, it is to avoid the situation where the building block input onto the supporting plate 6 is not accurately positioned, resulting in the top of the building block colliding with the positioning claw 10 during the rising process, resulting in the building block being unable to be clamped and positioned by the positioning claw 10. That is, the size of the building block that can be assembled is limited by the positioning claws 10 on all sides. Therefore, the above-mentioned optimized embodiment is further optimized as follows:

[0077] Extension plates 15 extending laterally are provided on all four sides of the support plate 6. The upper surface of the extension plate 15 is flush with the upper surface of the support plate 6. The extension plate 15 is located below the positioning claw 10, and the extension plate 15 can move along the clearance hole 9. Through the extension effect of the extension plate 15, the lower end of the positioning claw 10 can still cooperate with the support plate 6 when it is located outside the assembly cavity 402, avoiding the limitation of the size of the assembled building blocks caused by the positioning claws 10 on the four sides.

[0078] The secondary assembly mechanism 8 includes a transverse pneumatic component 801, a transverse push rod 802, and a feed pipe 803. The transverse pneumatic component 801 and the feed pipe 803 are both arranged on the outer wall of the guide cover 12 opposite to the transverse hole 5. One end of the transverse push rod 802 is connected to the transverse pneumatic component 801.

[0079] The guide cover 12 is provided with a first through hole 16 and a feed hole 17, both of which are connected to the interior thereof. The first through hole 16 is located above the feed hole 17. The transverse push rod 802 is aligned with the first through hole 16 and the transverse hole 5. The size of the transverse push rod 802 is adapted to the size of the first through hole 16 and the transverse hole 5.

[0080] One end of the feeding tube 803 is connected to the feeding hole 17, and the other end of the feeding tube 803 is bent upward so that the magnets in the feeding tube 803 are transported by gravity;

[0081] The top of the slider 13 is provided with a receiving groove 18 for receiving and limiting the magnets. The magnets output by the feeding tube 803 are transported to the top receiving groove 18 of the slider 13 at the initial position through the feeding hole 17;

[0082] After the positioning claw 10 clamps the building block into position, the slider 13 is pushed upward as the supporting plate 6 continues to rise until the magnet in the receiving groove 18 is aligned with the transverse hole 5. At this time, the transverse hole 5 is also aligned with the embedding hole on the same side of the building block. Subsequently, the transverse pneumatic component 801 drives the transverse push rod 802 to pass through the receiving groove 18 and the transverse hole 5. As the transverse push rod 802 moves further into the assembly cavity 402, the transverse push rod 802 pushes the magnet in the receiving groove 18 to embed into the embedding hole on the corresponding side of the building block.

[0083] The embodiment of the secondary assembly mechanism 8 provided by the present invention not only realizes the automatic supply of magnets, but also adopts the slider 13 to perform a secondary pushing of the magnets to push the magnets between the transverse push rod 802 and the transverse hole 5, thereby avoiding the situation where the supplied magnets directly reach between the transverse hole 5 and the transverse push rod 802 and the magnets automatically enter the assembly cavity 402 before the top of the building block rises above the transverse hole 5 due to mechanical vibration, which causes the magnets to be unable to be assembled on the building blocks. That is, the coordination of the supply of building blocks and the supply of magnets into the assembly cavity 402 is realized.

[0084] It should be noted that when the length and width of the building block are too smaller than the length and width of the assembly cavity 402, in order to prevent the magnet from falling when it is pushed into the assembly cavity 402, the problem can be solved by installing a catheter of an appropriate length in the transverse hole 5, or by installing an armature or magnet for adsorbing the magnet to be embedded at the end of the transverse push rod 802, or by installing a magnet positioning component that can be elastically extended at the end of the transverse push rod 802. The above technical problems can be solved by those skilled in the art using a variety of conventional technical means such as the above, and will not be elaborated here.

[0085] It is additionally noted that the vertical position of the guide cover 12 can be adjusted by disassembling it from the outer wall of the assembly cavity 402 to accommodate the assembly needs of building blocks of various sizes.

[0086] Among them, the initial assembly mechanism 3 includes a hole seat 301, a vertical push rod 302 and a vertical pneumatic component 303. The top and bottom of the hole seat 301 are provided with a second through hole 19 aligned with the vertical hole 2 and adapted to the size. The vertical push rod 302 is aligned with the vertical hole 2 and the second through hole 19, and one end is connected to the corresponding vertical pneumatic component 303 set on the hole seat 301. One end of the hole seat 301 is provided with a tail warp channel 20 connected to the second through hole 19, and the end of the tail warp channel 20 away from the second through hole 19 is bent upward.

[0087] The magnet in the tail tilt channel 20 moves toward the second through hole 19 under the action of gravity. When the magnet reaches the second through hole 19, the vertical pneumatic component 303 drives the vertical push rod 302 to push the magnet in the second through hole 19 toward the vertical hole 2 until the magnet is embedded in the building block in the building block conveying pipe 1, thereby completing the assembly of the magnets at the top and bottom of the building block.

[0088] Among them, the lifting mechanism 7 is arranged below or at the bottom of the secondary assembly box 4, and the lifting mechanism 7, the horizontal driving component, and the vertical pneumatic component 303 are any driving components or driving devices with linear driving functions, such as cylinders, oil cylinders, electric push rods, etc.

[0089] Preferably, the building block conveying pipeline 1 includes a supply pipe 101 and a push pipe 102, one end of the push pipe 102 is connected to the feed port, and the feed port and the discharge port are arranged along the length direction of the push pipe 102;

[0090] One end of the supply pipe 101 is connected to the side wall of the push pipe 102 and is perpendicular to the push pipe 102. The side wall of the push pipe 102 is provided with a transfer hole 21. The building blocks transported by the supply pipe 101 enter the push pipe 102 through the transfer hole 21.

[0091] A pushing cylinder 22 and a pushing plate 29 connected to the pushing cylinder 22 are provided in the pushing tube 102 . The pushing cylinder 22 pushes the building blocks in the pushing tube 102 entering through the transfer hole 21 onto the supporting plate 6 with the help of the pushing plate 29 .

[0092] Compared to directly transporting the building blocks into the transfer channel 401, using the push cylinder 22 of the push tube 102 to push the building blocks fed from the supply tube 101 into the transfer channel 401 one by one is more conducive to precise control of the building block push position. In addition, it helps to ensure that the building blocks can still be accurately moved into the transfer channel 401 even if the automatic building block supply device fails.

[0093] Preferably, the initial assembly mechanism 3 is provided on the supply tube 101. The advantage is that after the building blocks in the supply tube 101 have completed the assembly of magnets on the top and bottom and are conveyed to the push tube 102, the next building block conveyed can be immediately assembled with magnets on the top and bottom, that is, two building blocks with magnets on the top and bottom can exist in the building block conveying pipeline 1 at the same time, which is conducive to improving production efficiency.

[0094] A further improvement on the above embodiment is that the length of the transfer hole 21 in the longitudinal direction of the push tube 102 is greater than the length of the supply tube 101, and the end of the transfer hole 21 close to the secondary assembly box 4 is aligned with the supply tube 101. A positioning hole 30 is provided on the side of the supply tube 101 away from the secondary assembly box 4, and a positioning rod 23 is slidably inserted into the positioning hole 30;

[0095] A back plate 24 is provided on the back of the push plate 29 away from the secondary assembly box 4, and one side of the back plate 24 extends into the transfer hole 21;

[0096] The back surface of the back plate 24 away from the push plate 29 is connected to a linkage rod 26 via an elastic component 25. One end of the linkage rod 26 extending toward the supply pipe 101 is connected to the positioning rod 23.

[0097] A guide hole 27 parallel to the positioning hole 30 is provided at one end of the transfer hole 21 away from the secondary assembly box 4 , and a guide rod 28 connected to the linkage rod 26 is slidably inserted into the guide hole 27 .

[0098] Specifically, when the pushing cylinder 22 drives the pushing plate 29 to push the building blocks in the pushing tube 102 toward the upper plate, the back plate 24 on the back of the pushing plate 29 is located in the transfer hole 21 on one side. When the building blocks located in the pushing tube 102 on one side of the transfer hole 21 are pushed away, the back plate 24 is located on the side of the supply tube 101. At this time, the building blocks at the end of the supply tube 101 are clamped and positioned in both directions by the back plate 24 and the subsequently transported building blocks. At the same time, the back plate 24 pulls the linkage rod 26 with the help of elastic forces such as tension springs or ribs, so that the linkage rod 26 pushes the positioning rod 23 to move into the supply tube 101, so that the building blocks at the end of the supply tube 101 are clamped and positioned in the front-to-back direction by the positioning rod 23 and the inner wall of the supply tube 101, so that the top and bottom embedding holes of the building blocks at the end of the supply tube 101 are aligned with the vertical hole 2, so that the subsequent initial assembly mechanism 3 can accurately embed the magnets into the embedding holes at the top and bottom of the building blocks.

[0099] It is understood from common technical knowledge that the present application may be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are merely illustrative in all respects and are not intended to be exclusive. All modifications that come within the scope of this application or are equivalent to the scope of this application are intended to be included in this application.
