Description

TECHNICAL FIELD

[0001] The utility model relates to production manufacturing technical field especially relates to a flat product's stacking structure and automatic stacking equipment. BACKGROUND

[0002] In the production and storage process of thin flat products such as TV backboard and refrigerator door plate, efficient and safe stacking mode is crucial. However, such products usually have a thickness of only 0.5-0.8mm, poor rigidity, and are prone to deformation. At the same time, the straightness of the bottom surface of the three sides of the product is strictly required, usually not more than 0.2mm, to ensure the subsequent assembly or use performance. In addition, the functional surface of the product is extremely sensitive to stress deformation, and the central area is also prone to collapse due to its own weight and bowl-shaped structure. These characteristics make it difficult to directly apply traditional stacking methods, and if single-piece storage is adopted, it will result in extremely low storage space utilization. Currently, the stacking of such products mainly relies on manual operation. The typical process is to place four corner support blocks as a base on a tray in advance, and then 4-5 workers lift a flat product together and carefully place it on the corner support blocks. Then, the workers place another layer of corner support blocks on the product that has been placed, and so on, stacking the next product on the previous layer of support blocks, usually up to about 50 layers.

[0003] The above-mentioned manual stacking process has many drawbacks. First, the corner support blocks not only occupy a large amount of storage and transportation space, but also are prone to being stuck together due to their large number, making them difficult to separate and inconvenient to manage. Second, the central area of large-size products is at a higher risk of collapse due to its own weight, requiring additional placement of a central support bubble block, further increasing the complexity of the operation. In addition, manual stacking requires a large number of workers, resulting in high labor costs, and the lifting and placing process is time-consuming and labor-intensive, with long production cycles and low efficiency. In addition, during the manual lifting and placing process, the edges of the product are easily damaged or deformed. SUMMARY

[0004] To address the problems identified in the background art, the present application provides a stacking structure for flat products, which improves stacking efficiency, reduces labor costs, significantly reduces product damage, and effectively improves inventory utilization by using a central support method.

[0005] To achieve the above-mentioned utility model purposes, the utility model adopts the following technical solutions:

[0006] In some embodiments of the present application, a stacking structure for flat products is provided, comprising:

[0007] at least two layers of stacked flat products;

[0008] at least one support block for supporting the adjacent two layers of flat products;

[0009] The support block is directly supported between two adjacent flat products, and is used to support the central region of the flat products; the support block has oppositely arranged upper and lower support surfaces, the upper support surface is used to support the upper flat product, and the lower support surface is used to support the lower flat product.

[0010] By using the central support, the problems of deformation, center collapse and low storage efficiency of the thin flat products during stacking are effectively solved, the stability and space utilization of the stack are improved, the operation is simplified, and the foundation for automatic stacking is laid.

[0011] In some embodiments of the present application, the support block comprises a hard support part and a soft part, and the soft part is arranged on the upper side and / or lower side of the hard support part and used to contact the flat product. By arranging the soft part on the support block, the stability and safety of the stack are further improved, the flat product is effectively protected, and the risk of damage to the product during stacking and transportation is reduced.

[0012] In some embodiments of the present application, the hard support part and the soft part are integrally formed by an injection molding process. Integrally forming the hard support part and the soft part forms a firm combination between the hard support part and the soft part; at the same time, integrally forming reduces the assembly process, simplifies the production process, improves the production efficiency, and reduces the production cost.

[0013] In some embodiments of the present application, the hard support part comprises an upper plate part, a lower plate part, and a cylindrical part connecting the upper plate part and the lower plate part; and the soft part at least partially covers the surfaces of the upper plate part and the lower plate part facing the flat product and the inner side surface of the cylindrical part. Covering the inner side surface of the cylindrical part with the soft part can integrate the soft parts on the upper and lower sides, and integrate the soft part and the hard support part.

[0014] In some embodiments of the present application, a plurality of support ribs are arranged between the upper plate part and the lower plate part, and the plurality of support ribs are uniformly distributed along the outer periphery of the cylindrical part. Arranging the support ribs effectively improves the structural strength of the support block, so that it can withstand greater pressure, thereby improving the stability and safety of the stack, and is particularly suitable for stacking heavier or larger flat products.

[0015] In some embodiments of the present application, the surface of the soft part has a rough surface. By arranging a rough surface on the surface of the soft part, the friction between the support block and the flat product is effectively increased, the stability of the stack is improved, and the adhesion between the two is significantly reduced, thereby avoiding the generation of vacuum adsorption, facilitating the taking and placing of products, and improving the efficiency of stacking and unstacking.

[0016] In some embodiments of the present application, an automatic stacking device is provided for realizing the stacking structure described above, comprising:

[0017] a conveying line for conveying the flat products;

[0018] a stacking station for stacking the flat products;

[0019] a support block supply device for supplying support blocks to the conveying line;

[0020] a first mechanical arm device arranged on one side of the support block supply device for grabbing support blocks from the support block supply device and placing the support blocks on the flat products on the conveying line;

[0021] a second mechanical arm device arranged on the back side of the first mechanical arm device for grabbing the flat products with the support blocks placed thereon from the conveying line and placing the flat products on the stacking station.

[0022] The use of the automatic stacking device realizes automatic stacking of the flat products, improves the stacking efficiency, reduces the labor cost, and reduces the risk of damage to the products during handling and placement.

[0023] In some embodiments of the present application, a first visual detection device is further included for detecting the positions of the flat products on the conveying line and the positions of the support blocks placed by the first mechanical arm device. By adding the first visual detection device, the accuracy and automation degree of the placement of the support blocks are improved, further improving the stability and efficiency of the stacking.

[0024] In some embodiments of the present application, a second visual detection device is further included for detecting the placement positions of the support blocks on the stacking station. By adding the second visual detection device, the accuracy and flexibility of the stacking are improved, enabling more stable stacking.

[0025] In some embodiments of the present application, the support block supply device comprises:

[0026] a feeding mechanism, the feeding mechanism comprising a box, a lifting push plate, and a driving mechanism; the box is used to accommodate the support blocks to be supplied, the lifting push plate is arranged in the box and is used to push the support blocks in the box upward, and the driving mechanism is used to drive the lifting push plate to perform lifting movement;

[0027] a conveying mechanism for carrying and conveying the aligned support blocks;

[0028] a return mechanism for conveying the support blocks in the wrong direction back into the box.

[0029] The support block feeding device realizes automatic feeding, alignment and output of the support blocks, and recycling, thereby improving the efficiency and reliability of the automatic stacking equipment.

[0030] Compared with the prior art, the support block feeding device has the advantages and positive effects that:

[0031] The stacking structure of the flat products in the above embodiment specifically realizes the following technical effects:

[0032] Effectively prevent center collapse: The center support directly acts on the center area of the flat products, providing more uniform support force, effectively preventing the center collapse of the products due to their own weight or the pressure of the upper products, especially for bowl-shaped products.

[0033] Effectively prevent edge stress and deformation: The center support avoids the flat product edges directly bearing the stacking pressure, thereby effectively preventing edge stress or extrusion, ensuring the straightness of the product side bottom surface and avoiding edge deformation.

[0034] Improve the stability of the stack: The center support makes the contact between the upper and lower flat products more stable, reducing the likelihood of sliding or tilting, thereby improving the overall stability of the stack.

[0035] Improve space utilization: Compared with the corner support, the center support occupies less space, allowing the flat products to be stacked more closely, thereby improving the space utilization of storage and transportation.

[0036] Simplify the operation: The placement operation of the center support is relatively simple, without the need for precise alignment of the four corners as with the corner support, reducing the difficulty of manual operation and making it easier to achieve automation.

[0037] The present application effectively solves the problems of deformation, center collapse and low storage efficiency during the stacking of thin flat products, improves the stability and space utilization of the stack, and simplifies the operation, laying the foundation for realizing automated stacking.

[0064] Referring to Figures 1-10 The present application provides some embodiments of a stack structure of flat panel products, and the present application describes a stack structure of flat panel products, which aims to solve the problems of easy deformation, center collapse and low storage efficiency in the stacking process of thin flat panel products. The core of the stack structure is to use support blocks to directly support the center area of adjacent two layers of flat panel products.

[0065] Referring to Figures 1-7 The stack structure 100 includes at least two layers of stacked flat panel products 110 and at least one support block 120.

[0066] The flat panel product 110 can be a thin product such as a television backboard, a refrigerator door panel, etc.

[0067] The support block 120 is used to support the adjacent two layers of flat panel products 110 and provide effective support to the center area of the product.

[0068] The support block 120 has oppositely arranged upper and lower support surfaces.

[0069] The upper support surface is used to support the upper layer of flat panel products 110, and the lower support surface is used to support the lower layer of flat panel products 110.

[0070] The support block 120 is directly placed above the central area of the lower flat product 110, and the upper flat product 110 is directly placed on the upper support surface of the support block 120.

[0071] In some embodiments of the present application, the support block 120 is arranged on the side of the flat product 110 away from the appearance surface, for supporting the central area of the product. The specific number and arrangement of the support blocks 120 can be adjusted according to factors such as the size, shape, weight, and stacking height of the flat product 110. As an example, a five-point support method can be used, i.e., five support blocks 120 are arranged in the central area of the flat product 110, with four support blocks 120 arranged in an approximate quadrilateral (e.g., square, rectangular) and the fifth support block 120 located at the center of the quadrilateral.

[0072] Compared with the traditional corner support method, the center support method used in the present application has the following significant advantages:

[0073] Effectively prevents central collapse: The center support directly acts on the central area of the flat product 110, providing more uniform support force and effectively preventing the product from collapsing in the center due to its own weight or the pressure from the product above, especially for bowl-shaped products.

[0074] Effectively prevents edge stress and deformation: The center support avoids the edges of the flat product 110 directly bearing the stacking pressure, effectively preventing edge stress or extrusion and ensuring the straightness of the product's side bottom surface, avoiding edge deformation.

[0075] Improves stacking stability: The center support makes the contact between the upper and lower flat products 110 more stable, reducing the likelihood of sliding or tilting and improving the overall stability of the stack.

[0076] Improves space utilization: Compared with corner support, the center support occupies less space, allowing the flat products 110 to be stacked more closely, thereby improving the space utilization for storage and transportation.

[0077] Simplifies operation: The placement of the center support is relatively simple and does not require precise alignment of the four corners as with corner support, reducing the difficulty of manual operation and making it easier to automate.

[0078] The present application effectively solves the problems of deformation, central collapse, and low storage efficiency during the stacking of thin flat products 110, improves the stability and space utilization of the stack, and simplifies the operation, laying the foundation for automated stacking.

[0079] In some embodiments of the present application, the support block 120 includes a hard support portion 121 and a soft portion 122.

[0080] The hard support part 121 of the support block 120 mainly serves as a load-bearing function, and is usually made of materials with high strength and rigidity, such as plastic (e.g., PP, ABS), metal, etc.

[0081] The soft part 122 is arranged on the upper side and / or lower side of the hard support part 121, and is used to directly contact the flat panel product 110. The soft part 122 is usually made of elastic materials, such as rubber, silicone, TPE, etc.

[0082] The arrangement of the soft part 122 has the following advantages:

[0083] Buffering effect: The soft part 122 can buffer the impact and vibration between the upper and lower flat panel products 110, reducing the damage to the products during stacking and transportation.

[0084] Anti-slip effect: The soft part 122 has a high friction coefficient, which can increase the friction between the support block 120 and the flat panel product 110, preventing the product from slipping during stacking, and improving the stability of the stack.

[0085] Protecting the surface of the product: The soft surface of the soft part 122 can effectively protect the functional surface of the flat panel product 110, avoiding scratches or wear.

[0086] The soft part 122 can be arranged only on the upper side or lower side of the hard support part 121, or on both sides. When arranged on only one side, the side in contact with the functional surface is usually selected to arrange the soft part 122 to maximize the protection of the product. When arranged on both sides, more comprehensive buffering and anti-slip effects can be provided.

[0087] The embodiment further improves the stability and safety of the stack by arranging the soft part 122 on the support block 120, effectively protects the flat panel product 110, and reduces the risk of damage to the product during stacking and transportation.

[0088] In some embodiments of the present application, the hard support part 121 and the soft part 122 are integrally formed by injection molding.

[0089] The integral molding forms a firm bond between the hard support part 121 and the soft part 122, avoiding the situation of falling off or loosening during subsequent use, improving the reliability and service life of the support block 120; at the same time, the integral molding reduces the assembly process, simplifies the production process, improves the production efficiency, and reduces the production cost; in addition, the injection molding process can accurately control the size and shape of the product, ensuring the consistency of each support block 120, thereby improving the stability and consistency of the stack.

[0090] Specifically, the integrally formed hard support part 121 and soft part 122 can be achieved by using a two-color injection molding or overmolding process. Two-color injection molding refers to using two different plastic materials on the same injection molding machine, through two or more injection molding, one-time molding of the hard support part 121 and the soft part 122. Overmolding is to first injection mold the hard support part 121, then put the hard support part 121 into another mold, and then injection mold the soft part 122 to cover the hard support part 121.

[0091] In some embodiments of the present application, as shown in Figure 6 The hard support part 121 includes an upper plate part 1211, a lower plate part 1212, and a cylindrical part 1213 connecting the upper plate part 1211 and the lower plate part 1212. The soft part 122 at least partially covers the surfaces of the upper plate part 1211 and the lower plate part 1212 facing the flat panel product 110, and the inner side surface of the cylindrical part 1213.

[0092] The upper plate part 1211 and the lower plate part 1212 are the main force-bearing parts of the support block 120, and their shape and size need to be designed according to the size and weight of the flat panel product 110.

[0093] The cylindrical part 1213 connects the upper plate part 1211 and the lower plate part 1212 to form a hollow structure, which not only reduces the weight of the support block 120, but also improves its compressive strength. The cylindrical part 1213 can be circular, square or other suitable shapes.

[0094] The soft part 122 at least partially covers the surfaces of the upper plate part 1211 and the lower plate part 1212 facing the flat panel product 110, and the inner side surface of the cylindrical part 1213. Covering the surfaces of the upper plate part 1211 and the lower plate part 1212 can directly contact the flat panel product 110, which can protect the surface of the product; covering the inner side surface of the cylindrical part 1213 can integrate the soft parts 122 on both sides, and make the soft part 122 and the hard support part 121 tightly integrated.

[0095] The soft part 122 can completely cover the surfaces of the upper plate part 1211 and the lower plate part 1212, or only cover part of the area, such as only cover the edge area or the center area. The covering method can be designed according to specific needs.

[0096] In some embodiments of the present application, a support rib 1214 is arranged between the upper plate part 1211 and the lower plate part 1212.

[0097] To further improve the structural strength of the support block 120, especially to prevent the cylindrical portion 1213 from deforming or collapsing when bearing a larger pressure, several support ribs 1214 are arranged between the upper plate portion 1211 and the lower plate portion 1212 in this embodiment. The support ribs 1214 are uniformly distributed along the outer periphery of the cylindrical portion 1213, which can effectively disperse the pressure and improve the radial strength of the cylindrical portion 1213.

[0098] The number, shape and size of the support ribs 1214 can be designed according to specific requirements. For example, 3, 4 or more support ribs 1214 can be provided. The cross section of the support ribs 1214 can be rectangular, triangular, trapezoidal or other suitable shapes. The thickness and height of the support ribs 1214 also need to be reasonably designed according to the size of the support block 120 and the pressure it bears.

[0099] The support ribs 1214 can be integrally formed with the upper plate portion 1211 and the lower plate portion 1212, or connected by welding, bonding or other methods. Integrally forming can improve the connection strength and production efficiency.

[0100] This embodiment effectively improves the structural strength of the support block 120 by arranging the support ribs 1214, so that it can bear a larger pressure, thereby improving the stability and safety of the stack, especially suitable for stacking heavier or larger flat-shaped products 110.

[0101] In some embodiments of the present application, the surface of the soft portion 122 has a rough surface.

[0102] The rough surface of the soft portion 122 has micro or macro concave-convex structures. These concave-convex structures can be regular textures (such as wavy, grid-like, striped) or irregular granular.

[0103] The rough surface increases the contact area between the soft portion 122 and the flat-shaped product 110, and provides more micro engagement points. When the flat-shaped product 110 is placed on the support block 120, these micro engagement points can effectively hinder the product from sliding along the support surface, improving the stability of the stack, especially when the stack is high or subjected to external vibration, which can better prevent the product from falling.

[0104] In addition, when smooth surfaces are tightly fitted, vacuum adsorption phenomenon is easily formed, causing difficulty in picking and placing, while the rough surface effectively avoids vacuum adsorption.

[0105] This embodiment effectively increases the friction between the support block 120 and the flat-shaped product 110 by arranging a rough surface on the surface of the soft portion 122, improves the stability of the stack, and significantly reduces the adhesion between the two, avoiding the generation of vacuum adsorption, thereby facilitating the picking and placing of the product, and improving the efficiency of stacking and unstacking.

[0106] In some embodiments of the present application, as shown in Figure 7 The stacking structure 100 further comprises a carrier 130 for carrying the flat products 110. The support block 120 is also placed on the carrier 130 for supporting the central region of the flat product 110.

[0107] Referring to Figures 8-11 The present application also provides some embodiments of an automated stacking device 200 for implementing the above-mentioned stacking structure 100.

[0108] The automated stacking device 200 comprises a conveying line 210, a stacking station 220, a support block supply device 230, a first robotic device 240 and a second robotic device 250.

[0109] The conveying line 210 is used to convey the flat products 110 from a production line or other station to a predetermined position.

[0110] The conveying line 210 can be a roller conveying line 210, a belt conveying line 210 or a chain conveying line 210, etc., and the appropriate type is selected according to the characteristics of the product. The conveying line 210 is provided with a positioning mechanism (such as a stop block, a sensor, etc.) to ensure that the flat products 110 can be accurately stopped at the predetermined position, facilitating subsequent robotic operations.

[0111] The stacking station 220 is the area where the stacking of the flat products 110 is performed. This station can be a fixed platform, a movable platform such as a stacking trolley, or a liftable platform.

[0112] The support block supply device 230 is responsible for providing the support blocks 120 to the conveying line 210.

[0113] The first robotic device 240 is provided on one side of the support block supply device 230, and is used to grab the support blocks 120 from the support block supply device 230 and accurately place the support blocks 120 on the central region of the flat products 110 on the conveying line 210.

[0114] The first robotic device can be a multi-joint robot, a parallel robot or a simple pneumatic / hydraulic actuator. In order to ensure the accuracy of the placement of the support blocks 120, the first robotic device can be equipped with a visual positioning system or a force sensor.

[0115] The second robotic device 250 is provided on the rear side of the first robotic device 240, and is used to grab the flat products 110 on which the support blocks 120 have been placed from the conveying line 210 and place them on the stacking station 220.

[0116] The second robot can also be a multi-joint robot, a parallel robot or a simple pneumatic / hydraulic actuator. In order to avoid damaging the product during grabbing, the robot can be equipped with special grippers, such as vacuum suction cups, pneumatic grippers or flexible grippers.

[0117] Example of the working process of the automated stacking device 200:

[0118] 1. The conveying line 210 transports the flat products 110 to the predetermined position and stops.

[0119] 2. The support block supply device 230 sequentially transports the support blocks 120 to the predetermined position.

[0120] 3. The first robot device 240 grabs the support blocks 120 and accurately places them in the center area of the flat products 110 on the conveying line 210.

[0121] 4. The second robot device 250 grabs the flat products 110 with the placed support blocks 120 and places them on the stacking station 220.

[0122] 5. Repeat the above steps until the stacking of all products is completed.

[0123] This embodiment realizes the automatic stacking of flat products 110 by using the automated stacking device 200, improves the stacking efficiency, reduces the labor cost, and reduces the risk of product damage during handling and placement.

[0124] In order to improve the working efficiency, the support block supply device 230 and the first robot device 240 can be equipped with two sets, and the two sets of first robot devices 240 simultaneously grab the support blocks 120 and place them on the flat products 110.

[0125] In some embodiments of the present application, the automated stacking device 200 is also provided with a first visual detection device 260. The first visual detection device 260 is used to detect the position of the flat products 110 on the conveying line 210 and the position of the support blocks 120 placed by the first robot device 240.

[0126] The first visual detection device 260 usually includes one or more industrial cameras.

[0127] The first visual detection device 260 captures the image of the flat products 110 on the conveying line 210 through the camera and analyzes the image using image processing software to identify the edges or feature points of the flat products 110, thereby accurately determining the position and attitude of the products.

[0128] The first visual detection device 260 can also detect the position of the first mechanical arm device 240 placing the support block 120, to ensure that the support block 120 is accurately placed at a specific position of the flat panel product 110.

[0129] The present embodiment improves the accuracy and automation of the placement of the support block 120 by adding the first visual detection device 260, further improving the stability and efficiency of the stacking.

[0130] In some embodiments of the present application, the automated stacking device 200 is also provided with a second visual detection device 270.

[0131] The second visual detection device 270 is used to detect the position of the flat panel product 110 and / or the support block 120 that has been placed on the stacking station 220, which can assist the second mechanical arm device 250 in accurate placement, ensuring that the subsequently placed products can be accurately stacked on the already placed products, avoiding unstable stacking or product damage due to positional deviation.

[0132] At the same time, the stacking station 220 generally places the carrier 130 first, and places the support block 120 on the carrier 130 to lay the foundation before placing the flat panel product 110. The second visual detection device 270 can assist in detecting the laying of the foundation operation of the carrier 130.

[0133] The present embodiment improves the accuracy and flexibility of stacking by adding the second visual detection device 270, enabling more stable stacking.

[0134] In some embodiments of the present application, the support block supply device 230 includes a feeding mechanism, a conveying mechanism 232, and a return mechanism 233.

[0135] The feeding mechanism is used to accommodate the support blocks 120 to be supplied and to convey them upward. The feeding mechanism includes:

[0136] Box: The box is used to accommodate a large number of disordered stacked support blocks 120. The bottom of the box can be designed as an inclined surface to facilitate the movement of the support blocks 120 to the lifting push plate 231.

[0137] Lifting push plate 231: The lifting push plate 231 is arranged in the box and moves up and down to push the support blocks 120 at the bottom of the box upward, so that they can enter the conveying mechanism 232.

[0138] Driving mechanism: The driving mechanism is used to drive the lifting push plate 231 to move up and down. This mechanism can be a gas cylinder, a hydraulic cylinder, a motor-driven screw or a cam mechanism, etc. The driving mechanism needs to be able to accurately control the lifting height and speed of the lifting push plate 231, to ensure that the support blocks 120 can be smoothly conveyed to the conveying mechanism 232.

[0139] The conveying mechanism 232 is used to carry and transport the aligned support blocks 120. The mechanism can be:

[0140] Vibrating hopper and track: the vibrating hopper orients the support blocks 120 by vibration and into a track that guides the support blocks 120 into a single-file arrangement and transport.

[0141] Belt conveyor and guide mechanism: the belt conveyor carries the support blocks 120 and a guide mechanism (e.g. a baffle, a guide rail) guides the support blocks 120 into an arrangement.

[0142] Multi-axis robot: the robot picks and places the support blocks 120 into designated positions.

[0143] The return mechanism 233 is used to transport the support blocks 120 that are not picked or incorrectly oriented back into the bin for recycling. The return mechanism 233 can be an inclined track that uses gravity to slide the support blocks 120 back into the bin, or a small conveyor belt that transports the support blocks 120 back into the bin.

[0144] The support block supply device 230 of the embodiment realizes automatic feeding, alignment and output of the support blocks 120, and performs recycling, thereby improving the efficiency and reliability of the automated stacking device 200.
