Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a material loading and unloading structure for double-sided grinding that can be flipped. Background Technology

[0002] In today's manufacturing industry, the quality and appearance of metal products are crucial to their market competitiveness. The key process of grinding and polishing metal products has multiple significant positive impacts.

[0003] From a performance improvement perspective, grinding and polishing can precisely remove various defects on the surface of metal products, such as burrs, oxide scale, scratches, and welding slag. After removing these defects, the microstructure of the metal surface is optimized and becomes denser. This effectively prevents the intrusion of external corrosive substances, greatly improving the metal's corrosion resistance. In terms of appearance improvement, grinding and polishing makes the metal surface smoother and flatter, significantly improving the product's appearance quality.

[0004] However, traditional metal product grinding and polishing is primarily done manually. This method has many drawbacks. First, the grinding and polishing process generates a large amount of dust and pollutants, severely polluting the working environment. These pollutants not only affect the air quality in the workshop but may also harm the surrounding environment. Second, long-term exposure to such a working environment can severely damage the health of operators, leading to respiratory diseases, pneumoconiosis, and other ailments. Furthermore, manual grinding and polishing is inefficient, requiring significant manpower and time. Moreover, due to the subjectivity and instability of manual operation, it is difficult to guarantee consistent grinding and polishing quality for each product, resulting in inconsistent product quality and impacting the overall product quality and market image.

[0005] With the continuous advancement of technology, automated equipment is increasingly being applied to the grinding and polishing processes of metal products. This automation has improved production efficiency and product quality to some extent, reducing the uncertainties associated with manual operation. However, most automated equipment currently has relatively limited functionality, confined to completing only the basic tasks of grinding and polishing. During operation, it cannot handle the orderly handling and placement of products. This often results in products being piled up haphazardly on the production floor, affecting not only the cleanliness and orderliness of the production site but also easily leading to errors in product quantity counting. Once the product quantity deviates, it can disrupt production plans, affecting the company's production schedule and delivery time, causing unnecessary losses. Utility Model Content

[0006] This invention overcomes the shortcomings of the prior art and provides a flip-up double-sided grinding material handling structure. It is equipped with a central conveying component, a material handling and grinding component, and a product and mesh picking component. It realizes automatic grinding, flipping, and grinding of the second side of the product, and enables the product to be placed in layers in an orderly manner in the material tray, making use of the storage space of the material tray so that the material tray can hold more products.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A flip-up double-sided grinding material handling structure includes a central conveying component, with a material handling and grinding component and a product and mesh picking component respectively arranged on both sides of the central conveying component; a grinding component is arranged on one side of the material handling and grinding component and the product and mesh picking component. The central conveying assembly includes a conveyor belt for conveying the material trays during the production process; The mesh picking component is equipped with a rotating gripper frame, and mesh grippers and product grippers are respectively installed at both ends of the rotating gripper frame; The material handling and polishing assembly includes a product gripping component, which grips the product and moves it to the polishing assembly for polishing. After one side of the product is polished, the product gripping component hands the product over to the product gripper, which places the product in a material tray. Once the bottom layer of the tray is full of product, the mesh gripper grips a mesh sheet and places it over the product. Subsequently, the product gripper continues to place the polished product on top of the mesh sheet. During the process of placing products with the product gripper, the conveyor belt drives the tray to move back and forth so that the products can be neatly arranged row by row.

[0008] Furthermore, the product gripping component includes a gripping base, in which a rotating rod is rotatably inserted. One end of the rotating rod is connected to a clamping cylinder, which is connected to a pair of grippers. The grippers are used to grip the product. After one side of the product is polished, the rotating rod rotates 180° to flip the product over, and then the product is delivered to the product gripper.

[0009] Furthermore, a gripping rotation motor is provided at one end of the gripping base, and the gripping rotation motor drives the rotating rod to rotate through the gripping linkage synchronous belt.

[0010] Furthermore, the material handling and grinding assembly includes a first transverse motor, which is connected to a first transverse module. A first transverse slide rail is provided on one side of the first transverse module. The first transverse slide rail is slidably connected to a first lifting module. The first lifting module is connected to the drive block of the first transverse module. The product gripping component is connected to the drive block of the first lifting module.

[0011] Furthermore, the polishing assembly is located at the end after the gripper extends; The polishing assembly includes a waste chip collection frame, in which a polishing motor is installed, and the polishing motor is directly connected to the polishing brush. The waste recycling box is equipped with a position adjustment linkage on its exterior.

[0012] Furthermore, the mesh picking component includes a second horizontal moving motor, which is connected to a second horizontal moving module. A second horizontal moving slide rail is provided on the side of the second horizontal moving module. The second horizontal moving slide rail is slidably connected to a second lifting module. The second lifting module is also connected to the moving block of the second horizontal moving module. The second lifting module is connected to a rotary cylinder, and the rotating gripper is connected to the rotary cylinder. When the rotating gripper rotates so that the product gripper faces upward, it is used to take out the product and the product with one side polished from the product gripping component. Then the rotating gripper rotates so that the product gripper faces downward, and the product gripper moves the product to the polishing component for the second side polishing. Then the product is placed on the material tray. When the gripper is rotated so that the mesh gripper faces downward, the mesh gripper can grab the mesh from the mesh storage component and then place the mesh on the tray.

[0013] Furthermore, the isolation mesh storage assembly includes a storage base frame, in which a lifting plate controlled by a motor and a lead screw is installed. The lifting plate is used to place a stack of mesh sheets. As the mesh sheets are gradually removed, the lifting plate gradually descends to ensure that the topmost mesh sheet is always at the same height. A limit plate is provided on the side of the lifting plate.

[0014] Furthermore, the tray is provided with an internal adjustment rod that is threadedly connected to the tray frame, and the end of the internal adjustment rod is rotatably connected to an internal adjustment position. The internal adjustment mechanism of the feed tray is used to limit the outer periphery of the product and the wire mesh.

[0015] Furthermore, two sets of trays are provided at both ends of the central conveying assembly to store the conveying assembly; One set of tray storage and conveying components is used to place empty trays onto the conveyor belt, and the other set of tray storage and conveying components is used to remove trays full of products from the conveyor belt. The material tray storage and conveying assembly includes a chain drive motor, which is connected to a linkage chain. The linkage chain is used to simultaneously drive two material tray lifting mechanisms. The material tray lifting mechanism includes a drive sprocket group, a driven sprocket group, and a lifting chain. The rotation of the drive sprocket group drives the lifting chain to move, thereby driving the driven sprocket group to rotate. At least one lifting support plate is provided on the outer periphery of the lifting chain. In this design, the drive sprocket assembly of the first material tray lifting mechanism meshes with the outer side of the linkage chain, while the drive sprocket assembly of the other material tray lifting mechanism meshes with the inner side of the linkage chain. The distance between the lifting support plates of the two material tray lifting mechanisms facing the middle is greater than the width of the conveyor belt but less than the width of the material tray.

[0016] Furthermore, the central conveying assembly, material handling and grinding assembly, grinding assembly, and product and mesh handling assembly are all located within the main frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. The system includes a central conveyor assembly, a material handling and grinding assembly, and a product and mesh sheet picking assembly. The central conveyor assembly enables automated material transport, requiring minimal manual intervention to stably and continuously transport the material tray according to a pre-set program. The product picking component automatically picks up products and moves them to the grinding assembly for grinding. After one side of the product is ground, the rotating rod automatically rotates 180° to flip the product over before handing it to the product gripper. The gripper then moves the other side of the product to the grinding assembly for grinding. When placing products, the gripper neatly arranges them on the tray according to pre-set rules and positions. Once the bottom layer of the tray is full, the mesh sheet gripper picks up a mesh sheet and places it on top of the products. Subsequently, the product gripper continues to place the ground products on the mesh sheets, repeating this cycle to achieve layered and orderly placement of products. This orderly placement method makes full use of the tray's storage space, allowing the tray to hold more products. It also facilitates subsequent product handling and storage, reducing the risk of collisions and damage during transport. The entire process requires no manual operation, significantly improving production efficiency and reducing labor costs.

[0018] 2. One set of the tray storage and conveying components automatically places empty trays onto the conveyor belt. A chain-driven motor drives a linked chain, which in turn drives the tray lifting mechanism, causing the lifting support plate to gradually descend. When it reaches the appropriate height, the empty tray accurately lands on the conveyor belt. The other set of tray storage and conveying components removes trays filled with products from the conveyor belt. Similarly, with the coordinated work of the chain-driven motor and the linked chain, the lifting support plate gradually rises, carrying the full tray to a higher position. This automated tray placement and retrieval method not only reduces the time and labor costs associated with manual handling but also avoids potential errors from manual operation, significantly improving production efficiency.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0022] like Figures 1 to 8 As shown, a flip-up double-sided grinding material handling structure includes a central conveying component 1, with a material handling and grinding component 3 and a product and mesh taking component 5 respectively arranged on both sides of the central conveying component 1; a grinding component 4 is arranged on one side of the material handling and grinding component 3 and the product and mesh taking component 5. The central conveying assembly 1 includes a conveyor belt 101, which is used to convey the material tray 102 during the production process. It can realize automated material transportation, reduce the time and labor costs of manual handling, and control the conveying speed and position according to the production rhythm to ensure that the material tray 102 reaches the designated position, providing a solid foundation for subsequent processes such as material picking, grinding and placement.

[0023] The mesh picking component 5 is equipped with a rotating gripper 506, and mesh grippers 5061 and product grippers 5062 are respectively provided at both ends of the rotating gripper 506. During the placement process, the product grippers 5062 can arrange the products neatly on the tray 102 according to the preset rules and positions, ensuring the orderliness and standardization of product placement.

[0024] The material handling and polishing component 3 includes a product gripping component 305, which grips the product and moves it to the polishing component 4 for polishing. After polishing one side of the product, the product gripping component 305 hands the product over to the product gripper 5062, which places the product in the material tray 102. When the bottom layer of the material tray 102 is filled with products, the mesh gripper 5061 grips a mesh sheet and covers the product. Then, the product gripper 5062 continues to lay the polished product on the mesh sheet. The above actions are repeated. Several layers of mesh sheets can be laid in a material tray 102 as needed, so that the storage space of the material tray 102 is fully utilized and the products are placed in a layered and orderly manner.

[0025] Throughout the process, as the product gripper 5062 places a product, the conveyor belt 101 moves the tray 102 back and forth according to the progress and position requirements of the product placement. This collaborative working method allows products to be neatly arranged row by row in the tray 102, avoiding the problem of messy product stacking, improving the cleanliness and management efficiency of the production site, and also facilitating subsequent handling and storage of products.

[0026] The product gripping component 305 includes a gripping base 3051. In this invention, the gripping base 3051 is made of aluminum profile. Therefore, during production, the aluminum profile can be cut as needed to adapt to different production scenarios and product requirements, greatly improving the flexibility of equipment design and manufacturing. Aluminum profiles are lightweight, reducing the overall weight of the product gripping component 305 compared to other metal materials. This not only reduces energy consumption during equipment operation but also lowers the load requirements on the support structure and drive components, extending the service life of related components. A rotating rod 3052 is rotatably inserted into the gripping base 3051. One end of the rotating rod 3052 is connected to a clamping cylinder 3053, which is connected to a pair of grippers 3054. The grippers 3054 are used to grip the product. After one side of the product is polished, the rotating rod 3052 rotates 180° to flip the product over, and then the product is handed over to the product gripper 5062. This design realizes the automatic flipping function of the product without manual intervention, which improves production efficiency, reduces labor costs, and also reduces the errors and risks that may be caused by manual operation.

[0027] A gripping rotation motor 3055 is provided at one end of the gripping base 3051. The gripping rotation motor 3055 drives the rotating rod 3052 to rotate via the gripping linkage synchronous belt 3056. The material picking and grinding assembly 3 includes a first transverse motor 301, which is connected to a first transverse module 302. A first transverse slide rail 303 is provided on one side of the first transverse module 302. The first transverse slide rail 303 is slidably connected to a first lifting module 304. The first lifting module 304 is connected to the drive block of the first transverse module 302. The product gripping component 305 is connected to the drive block of the first lifting module 304. The first transverse motor 301, the first transverse module 302, the first transverse slide rail 303, and the first lifting module 304 in the material picking and grinding assembly 3 cooperate with each other, enabling the product gripping component 305 to move flexibly in the horizontal and vertical directions. This multi-dimensional mobility allows the product gripping component 305 to accurately reach the designated position, enabling the gripping and handling of products in different locations. This improves the versatility and adaptability of the equipment, meets diverse production needs, and enhances production precision and efficiency.

[0028] The grinding assembly 4 is located at the extended end of the gripper 3054. The grinding assembly 4 includes a waste chip collection frame 401, within which a grinding motor 402 is installed. The grinding motor 402 is directly connected to the grinding brush 403. The main function of the waste chip collection frame 401 is to collect the waste chips generated during the grinding process. During grinding, the waste chips are collected in the waste chip collection frame 401, preventing them from flying around and polluting the working environment. This also facilitates the unified processing of the waste chips, maintaining a clean working environment and reducing hazards to equipment and operators.

[0029] The waste collection box 401 is externally equipped with a position adjustment link 404, which can adjust the position of the grinding component 4. Through the position adjustment link 404, the operator can adjust the position of the grinding component 4 according to the product size and grinding position requirements, ensuring that the grinding brush 403 can accurately contact the product surface, improving the accuracy and adaptability of grinding, and enabling the grinding component 4 to better meet the grinding needs of different products.

[0030] The mesh-grabbing component 5 includes a second horizontal movement motor 501, which is connected to a second horizontal movement module 502. A second horizontal movement slide rail 503 is provided on the side of the second horizontal movement module 502, and the second horizontal movement slide rail 503 is slidably connected to a second lifting module 504. The second lifting module 504 is also connected to the moving block of the second horizontal movement module 502. This connection method allows the second lifting module 504 to move horizontally under the drive of the second horizontal movement module 502, while also achieving vertical lifting motion itself. The vertical lifting function of the second lifting module 504 allows the mesh-grabbing component 5 to flexibly adjust its height position according to different operational needs. For example, when grabbing a product or mesh, it can accurately approach the target object; when placing a product or mesh, it can accurately place it at a suitable height, further enhancing the flexibility and accuracy of the operation.

[0031] The second lifting module 504 is connected to the rotary cylinder 505, and the rotating gripper 506 is connected to the rotary cylinder 505. When the rotating gripper 506 rotates so that the product gripper 5062 faces upward, it is used to take out the product and the product with one side polished from the product gripping component 305. Then the rotating gripper 506 rotates so that the product gripper 5062 faces downward. The product gripper 5062 moves the product to the polishing component 4 for the second side polishing. Then the product is placed on the material tray 102. When the gripper 506 is rotated so that the mesh gripper 5061 faces downward, the mesh gripper 5061 can grab the mesh from the mesh storage component 2 and then place the mesh on the tray 102.

[0032] The isolation mesh storage assembly 2 includes a storage base frame 201, within which is a lifting plate 202 controlled by a motor and lead screw. Its main function is to hold a stack of mesh panels. As the mesh panels are gradually removed by the mesh panel gripper 5061, the lifting plate 202 descends gradually under the precise control of the motor and lead screw. This design has significant advantages, ensuring that the topmost mesh panel remains at the same height. This is crucial for the mesh panel gripper 5061 to accurately grasp the mesh panels, avoiding difficulties or errors caused by changes in mesh panel height, and greatly improving the efficiency and accuracy of mesh panel grasping.

[0033] A limiting plate 203 is provided on the side of the lifting plate 202 to limit the mesh placed on the lifting plate 202. This prevents the mesh from shifting or slipping during storage, ensuring that the mesh is neatly and orderly arranged on the lifting plate 202. The presence of the limiting plate 203 improves the stability and standardization of mesh storage, allowing the mesh gripper 5061 to grasp the mesh more conveniently and accurately, further improving production efficiency.

[0034] The tray 102 has an internal adjusting rod 1021 threadedly connected to its frame. The end of the adjusting rod 1021 is rotatably connected to an internal adjusting stop 1022. The internal adjusting stop 1022 is used to limit the outer periphery of the product and wire mesh. This adjustable design allows the tray to adapt to products and wire mesh of different sizes and shapes. This increases the tray's versatility and flexibility, eliminating the need for companies to equip multiple trays for different product and wire mesh specifications, thus reducing production costs.

[0035] Two sets of material trays are provided at both ends of the middle conveying component 1 to store the conveying component 6; One set of tray storage and conveying components 6 is used to place empty trays 102 onto conveyor belts 101, and the other set of tray storage and conveying components 6 is used to remove trays 102 filled with products from conveyor belts 101. The material tray storage and conveying assembly 6 includes a chain drive motor 601, which is connected to a linkage chain 602. The linkage chain 602 is used to drive two material tray lifting mechanisms simultaneously. The advantage of this design is that it realizes the synchronous movement of the two material tray lifting mechanisms, ensuring the coordination and consistency of material tray lifting, avoiding errors in the material tray placement or removal process that may be caused by asynchrony, and improving production efficiency and stability.

[0036] The material tray lifting mechanism includes a drive sprocket assembly 603, a driven sprocket assembly 604, and a lifting chain 605; the rotation of the drive sprocket assembly 603 drives the lifting chain 605 to move, thereby driving the driven sprocket assembly 604 to rotate; at least one lifting support plate 606 is provided on the outer periphery of the lifting chain 605; the lifting support plate 606 is used to pick up and put down the material tray 102.

[0037] Among them, the drive sprocket group 603 of the first material tray lifting mechanism is engaged with the outer side of the linkage chain 602, and the drive sprocket group 603 of the other material tray lifting mechanism is engaged with the inner side of the linkage chain 602. The distance between the lifting support plates 606 of the two material tray lifting mechanisms facing the middle is greater than the width of the conveyor belt 101 and less than the width of the material tray 102.

[0038] Among them, the lifting support plate 606 of the material tray storage and conveying component 6, which places the empty material tray 102 at the conveyor belt 101, gradually descends. When the lifting support plate 606 descends to a height lower than the conveyor belt 101, the empty material tray 102 on the two lifting support plates 606 falls onto the conveyor belt 101, realizing the automatic delivery of the empty material tray 102. The lifting support plate 606 of the tray storage conveying component 6, which carries the tray 102 filled with products away from the conveyor belt 101, gradually rises. When the tray 102 filled with products is brought between the two lifting support plates 606 by the conveyor belt 101, the tray 102 filled with products is carried to a higher position as the two lifting support plates 606 gradually rise, thus completing the automatic removal of the tray 102 filled with products.

[0039] The central conveyor assembly 1, the material handling and grinding assembly 3, the grinding assembly 4, and the product and mesh handling assembly 5 are all housed within the main frame 7. The main frame 7 provides a stable support structure for these components, organically integrating them and making the entire production system layout more compact and rational. It effectively reduces mutual interference between components, ensuring their normal operation, and also facilitates unified management and maintenance of the entire production system.

[0040] The material handling mechanism of this utility model includes a central conveying component 1, a material handling and grinding component 3, and a product and mesh sheet picking component 5. The central conveying component 1 achieves automated material transportation, requiring no frequent manual intervention, and can stably and continuously convey the material tray 102 according to a preset program. The product gripping component 305 can automatically grab the product and move it to the grinding component 4 for grinding. After one side of the product is ground, the rotating rod 3052 will automatically rotate 180° to flip the product over, and then deliver the product to the product gripper 5062. The product gripper 5062 can move the other side of the product to the grinding component 4 for grinding. When placing the product, the product gripper 5062 can neatly arrange the product on the material tray 102 according to preset rules and positions. When the bottom layer of the material tray 102 is filled with products, the mesh sheet gripper 5061 grabs a mesh sheet and covers the top of the products. Subsequently, the product gripper 5062 continues to lay the polished products onto the mesh, repeating this process to achieve layered and orderly placement of the products. This orderly placement method makes full use of the storage space of the material tray 102, allowing it to hold more products. It also facilitates subsequent product handling and storage, reducing the risk of collisions and damage during transport. The entire process requires no manual operation, significantly improving production efficiency and reducing labor costs.

[0041] One set of the tray storage and conveying assembly 6 automatically places empty trays 102 onto the conveyor belt 101. It uses a chain drive motor 601 to drive a linkage chain 602, which in turn drives the tray lifting mechanism, causing the lifting support plate 606 to gradually descend. When it reaches the appropriate height, the empty tray 102 accurately lands on the conveyor belt 101. The other set of tray storage and conveying assembly 6 removes trays 102 filled with products from the conveyor belt 101. Similarly, with the coordinated work of the chain drive motor 601 and the linkage chain 602, the lifting support plate 606 gradually rises, carrying the full tray 102 to a higher position. This automated tray placement and retrieval method not only reduces the time and labor costs of manual handling but also avoids errors that may occur during manual operation, greatly improving production efficiency.

[0042] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
