Technical Field

[0001] This utility model relates to the field of paper box assembly technology, and in particular discloses an automatic magnet attaching device for paper boxes. Background Technology

[0002] In the paper box packaging industry, automated cardboard box and magnet bonding equipment has been widely used to improve production efficiency and reduce labor costs. However, existing automated cardboard box magnet bonding equipment suffers from poor coordination and insufficient automation. The lack of effective cooperation between different devices leads to inconsistencies in the processes of cardboard box feeding, magnet supply, gluing, and bonding, resulting in low bonding efficiency and difficulty in meeting the demands of large-scale production. Furthermore, some equipment still requires manual assistance to complete key steps, increasing labor input and increasing the risk of errors due to human operation, which can affect the stability of product quality. Utility Model Content

[0003] In order to overcome the technical problems of poor connection and low efficiency in the magnet assembly process of cardboard boxes in the existing technology, the purpose of this utility model is to provide a highly automated automatic magnet attaching device for cardboard boxes, so as to solve the above-mentioned technical problems in the existing technology.

[0004] To achieve the above objectives, this utility model provides an automatic magnet mounting device for cardboard boxes, comprising a frame, a first feeding device, a second feeding device, an adhesive supply device, a mounting robot, and a mounting worktable, all mounted on the frame. The first feeding device supplies external cardboard boxes to the mounting worktable, the second feeding device supplies magnets to the mounting robot, and the adhesive supply device, in cooperation with the mounting robot, provides adhesive for mounting the magnets and cardboard boxes.

[0005] Furthermore, the first feeding device includes a first support member mounted on the frame, a first conveyor belt rotatably mounted on the first support member, a first driving member connected to the first conveyor belt, and a pitch adjustment assembly reciprocatingly mounted on the first conveyor belt; the pitch adjustment assembly includes a second support member mounted on the first support member and two baffle members slidably mounted on the second support member, the moving direction of the baffle members being perpendicular to the conveying direction of the first conveyor belt, and the two baffle members being close to or far from each other to adapt to paper boxes of different sizes.

[0006] Furthermore, the automatic magnet mounting equipment also includes a positioning device, which includes a first lead screw module disposed on the mounting worktable, a first positioning member and a second positioning member reciprocatingly disposed at the output end of the first lead screw module, wherein the moving direction of the output end of the first lead screw module intersects with the conveying direction of the first feeding device, and the moving directions of the first positioning member and the second positioning member intersect with the moving direction of the output end of the first lead screw module, respectively; the first positioning member and the second positioning member are used to limit the cardboard box on the mounting worktable.

[0007] Furthermore, the first positioning member includes a second driving member and a first abutment member disposed at the output end of the second driving member. The second positioning member includes a third driving member and a second abutment member disposed at the output end of the third driving member. The second abutment member is obliquely disposed relative to the paper box and is used to abut against the inner wall of the paper box. The moving direction of the first abutment member is parallel to the conveying direction of the first feeding device. The paper box has a receiving position for accommodating a magnet, and the first abutment member is adapted to the receiving position.

[0008] Furthermore, the adhesive supply device includes an adhesive storage box disposed on one side of the application workbench for storing adhesive and a heating component disposed inside the adhesive storage box for heating the adhesive, the adhesive storage box having an air gap for magnets to adhere the adhesive.

[0009] Furthermore, the glue supply device also includes a glue-applying roller that is rotatably disposed in the glue storage box and a glue-applying motor connected to the glue-applying roller. The material-applying robot picks up the magnet supplied by the second feeding device and causes the magnet to pass through the clearance part to contact the glue-applying roller.

[0010] Furthermore, the second feeding device includes a receiving member for accommodating a magnet, an ejector member that reciprocates relative to the receiving member, a magnet feeding member that cooperates with the receiving member, and a fourth driving member connected to the magnet feeding member for driving its reciprocating movement; the moving direction of the magnet feeding member and the moving direction of the ejector member are intersected, and the ejector member is used to transfer the magnet contained in the receiving member to the magnet feeding member.

[0011] Furthermore, the material-applying robot includes a third support member, a first lateral movement mechanism and a first lifting mechanism disposed on the third support member, a first linkage member connected between the first lateral movement mechanism and the first lifting mechanism, and a magnet pickup member disposed at the output end of the first lifting mechanism, wherein the movement directions of the first lateral movement mechanism and the first lifting mechanism intersect each other.

[0012] Furthermore, the magnet pickup component employs a parallel opening and closing cylinder to drive the gripper to pick up the magnet, a vacuum suction cup assembly to drive the suction cup to attract the magnet, or an electromagnet assembly to energize and attract the magnet.

[0013] Furthermore, the automatic magnet mounting equipment also includes a discharge device and a discharge robot that is reciprocatingly mounted on the frame and used in conjunction with the discharge device. The discharge device has the same structure as the first feeding device, and the movement direction of the discharge robot intersects with the conveying direction of the discharge device. The discharge robot includes a seventh driving component, a second guide rail slider assembly connected to the seventh driving component, and a removal component located at the output end of the second guide rail slider assembly. The movement direction of the removal component is perpendicular to the conveying direction of the first conveyor belt. The seventh driving component drives the removal component to reciprocate via the second guide rail slider assembly to transfer the cardboard box with magnets mounted on the mounting worktable to the discharge device.

[0014] Furthermore, the first lateral movement mechanism includes a fifth driving member, a synchronous belt pulley assembly connected to the fifth driving member, and a first guide rail slider assembly connected to the synchronous belt pulley assembly.

[0015] The output end of the first lifting mechanism is provided with a second linkage component, and the magnetic pickup component is provided in multiple sets, with the multiple sets of magnetic pickup components slidably disposed on the second linkage component.

[0016] The output end of the second lead screw module is equipped with a proximity switch. The proximity switch is electrically connected to the fifth drive unit through the control system to prevent the magnet picked up by the magnet pickup unit driven by the fifth drive unit from being completely immersed in the glue storage box.

[0017] The technical principle of this utility model patent is as follows: First, in terms of paper box feeding, the first driving component in the first feeding device drives the first conveyor belt to rotate, transporting the paper box to the pasting worktable. The two baffles of the spacing adjustment component can slide along the second support component, adjusting the spacing according to the paper box size, thereby adapting to various paper box specifications. The positioning device controls the movement of the first positioning component and the second positioning component through the first lead screw module. The first abutting component is adapted to the paper box receiving position to remove any residue that may affect the magnetic pasting, and the second abutting component obliquely abuts against the inner wall of the paper box to achieve precise positioning of the paper box.

[0018] Inside the glue supply device, a heating component heats the adhesive in the glue storage box to ensure good adhesion. The glue application roller rotates under the drive of a glue application motor. The ejector of the second feeding device transfers the magnet from the receiving component to the magnet feeding component. A fourth drive component drives the magnet feeding component to reciprocate, supplying magnets to the bonding robot. The bonding robot picks up the magnet, passes it through the clearance section, and contacts the glue application roller, evenly adhering the adhesive. The bonding robot, relying on the first traversing mechanism and the first lifting mechanism, works in concert through the first linkage component to drive the magnet picking component to move precisely in three-dimensional space, completing magnet picking and bonding. The discharging device has the same structure as the first feeding device. The discharging robot transfers the bonded cardboard boxes to the discharging device, realizing an automated discharging process.

[0019] The beneficial effects of this invention are as follows: The adjustable spacing component of the first feeding device allows the equipment to easily handle cartons of different sizes, greatly improving its versatility and eliminating the need for cumbersome adjustments due to changes in carton specifications, thus significantly increasing production efficiency. The positioning device precisely limits the placement of the cartons, and combined with the precise motion control of the bonding robot, ensures the accuracy of the magnet placement position, improving product quality. The heating component and glue roller design of the glue supply device ensure that the adhesive maintains good adhesion and is applied evenly, which is beneficial to enhancing the bonding effect between the magnet and the cartons. The second feeding device stably and accurately supplies magnets to the bonding robot, ensuring the continuity and stability of the bonding process. Attached Figure Description

[0032] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0033] Please see Figures 1 to 10As shown, this utility model discloses an automatic magnet mounting device for cardboard boxes, comprising a frame 1, a first feeding device 2, a second feeding device 3, an adhesive supply device 4, a mounting robot 5, and a mounting worktable 6, all mounted on the frame 1. The first feeding device 2 supplies external cardboard boxes to the mounting worktable 6. The second feeding device 3 supplies magnets to the mounting robot 5. The adhesive supply device 4, in cooperation with the mounting robot 5, provides adhesive for mounting the magnets and cardboard boxes. The mounting robot 5 is reciprocatingly mounted on the frame 1. The mounting robot 5 picks up the magnets supplied by the second feeding device 3, drives the magnets to adhere to the adhesive, and then mounts them onto the cardboard boxes supported by the mounting worktable 6.

[0034] Specifically, a first feeding device 2, a second feeding device 3, an adhesive supply device 4, a bonding robot 5, and a bonding worktable 6 are installed on the frame 1. The first feeding device 2 delivers external cardboard boxes to the bonding worktable 6. The second feeding device 3 supplies magnets to the bonding robot 5. The adhesive supply device 4 works with the bonding robot 5 to provide adhesive. The bonding robot 5 moves back and forth on the frame 1, picking up magnets, adhering adhesive to them, and then bonding them to the cardboard boxes. The layout and function of each device are clearly defined, realizing an automated process for bonding cardboard boxes and magnets, improving production efficiency, reducing manual operation, and lowering labor costs.

[0035] Specifically, the first feeding device 2 includes a first support member 21 (including a vertical frame and a support plate on the vertical frame) mounted on the frame 1. A first conveyor belt 22 is rotatably mounted on the first support member 21, and the first conveyor belt 22 is connected to a first drive member 23 (servo motor). The first conveyor belt 22 is provided with an adjustment assembly 24, which consists of a second support member 25 mounted on the first support member 21 and two baffle members 26 slidably mounted on the second support member 25. The baffle members 26 move in a direction perpendicular to the conveying direction of the first conveyor belt 22, and the two baffle members 26 move closer or further apart to adapt to different sized cardboard boxes.

[0036] Specifically, in this embodiment, the first feeding device 2 is used in conjunction with the carton forming machine. After the carton is formed by cornering the corner of the forming machine, it is transferred to the first conveyor belt 22 of the first feeding device 2 by the conveyor belt or the robot arm and then transported to the pasting worktable for positioning, so as to achieve seamless connection between magnet pasting and forming process. In actual use, the distance adjustment function of the distance adjustment component 24 can be used to connect to carton forming machines of different sizes to improve product flexibility.

[0037] In this embodiment, two second support members 25 are provided. Each second support member 25 includes two brackets 251 arranged on both sides of the first support member 21 along a direction perpendicular to the first conveyor belt 22, a guide shaft 252 rotatably disposed between the two brackets 251, a locking block 253 movably disposed on the guide shaft 252, and a connecting plate 254 disposed on the locking block 253. The baffle member 26 is connected to the end of the connecting plate 254, and the extension direction of the connecting plate 254 is perpendicular to the extension direction of the baffle member 26. In actual use, the baffle member 26 can be electrically driven, achieving automatic adjustment through a motor and screw mechanism; alternatively, scale markings can be provided on the baffle member 26 for convenient manual and rapid adjustment. This allows the equipment to adapt to feeding various sizes of cardboard boxes, improving equipment versatility, reducing equipment adjustment time due to changes in cardboard box specifications, and increasing production efficiency.

[0038] Specifically, the positioning device 9 consists of a first lead screw module 91 mounted on the material feeding worktable 6, and a first positioning element 92 and a second positioning element 93 that reciprocate at the output end of the first lead screw module 91. The moving direction of the output end of the first lead screw module 91 intersects with the conveying direction of the first feeding device 2, and the moving directions of the first positioning element 92 and the second positioning element 93 intersect with the moving direction of the output end of the first lead screw module 91, respectively.

[0039] The first positioning member 92 includes a second driving member 921 and a first abutment member 922 disposed at its output end; the second positioning member 93 includes a third driving member 931 and a second abutment member 932 disposed at its output end. The second abutment member 932 is obliquely arranged (i.e., the extension direction of the second abutment member 932 forms a 45-degree angle with the extension direction of the side wall of the paper box) to abut against the inner wall of the paper box. The moving direction of the first abutment member 922 is parallel to the conveying direction of the first feeding device 2, and the first abutment member 922 is adapted to the receiving position of the paper box for accommodating the magnet.

[0040] The specific process for positioning incoming cardboard boxes is as follows:

[0041] Paper box conveying: The first conveyor belt 22 of the first feeding device 2 transfers the paper box to the pasting worktable 6.

[0042] Positioning device activated:

[0043] The first lead screw module 91 drives the positioning component to move: the first lead screw module 91 moves in a direction that intersects with the feeding direction, such as perpendicular to the conveying direction, thereby driving the first positioning component 92 and the second positioning component 93 to move closer to the paper box simultaneously.

[0044] The first positioning element 92 operates as follows: The second driving element 921 (cylinder) drives the first abutment 922 to move parallel to the feeding direction, inserting it into the magnet receiving position of the cardboard box (or abutting the side wall of the cardboard box), removing any residual paper scraps or glue residue, and ensuring the surface of the receiving position is clean. The first abutment 922 is wrapped with an elastic material such as silicone to avoid scratching the cardboard box.

[0045] The second positioning component 93 operates as follows: The third driving component 931 drives the second abutting component 932 to move at a 45° angle, abutting the inner wall of the paper box, applying lateral pressure through the inclined contact surface, correcting the offset angle of the paper box, and making it strictly aligned with the reference surface of the pasting worktable 6.

[0046] Double limiting: The first contact 922 is adapted to the receiving position to ensure the accurate placement of the magnet; the oblique pushing force of the second contact 932 makes the cardboard box fit tightly against the positioning reference of the worktable, eliminating displacement errors caused by conveying vibration.

[0047] Positioning completion signal: After the carton position is calibrated, the control system receives feedback signals from position sensors (such as photoelectric switches) and triggers the placement robot 5 to start the placement process.

[0048] In actual use, the first contact 922 and the second contact 932 can be made of elastic material. The first contact 922 can enter the receiving position with the help of the thrust of the first cylinder to remove any debris that may exist in the receiving position (such as the residual material of the paper box cut in the previous station) so as to better adapt to different paper box surface conditions; the driving component can also be selected from different types of electric push rods.

[0049] Specifically, in another embodiment, the applying robot 5 can attach the picked-up magnet to the side wall of the cardboard box after it has been positioned by the positioning device 9, using the first lifting mechanism 53, the first traversing mechanism 52, and the magnet picking member. In actual use, the first contact member 922 and the second contact member 932 are used to clamp and hold one side wall of the cardboard box for fixation. Then, the applying robot 5 picks up the magnet, picks up the adhesive from the glue supply device, and attaches it to the inner or outer wall of the side wall of the cardboard box. At this time, the magnets in the receiving chamber 31 are arranged vertically rather than stacked horizontally to cooperate with the applying robot 5's attaching action.

[0050] Specifically, the glue supply device 4 has a glue storage box 41 on one side of the plating workbench 6 to store the adhesive. The glue storage box 41 is equipped with a heating component to heat the adhesive. The glue storage box 41 has heat insulation plates 411 on both sides. The glue storage box 41 has a clearance for the magnet to adhere the adhesive. A glue application roller 42 is rotatably installed in the glue storage box 41 and connected to a glue application motor 43 (a combination of a servo motor and a synchronous pulley). After the plating robot 5 picks up the magnet, it makes it pass through the clearance to contact the glue application roller 42, thereby achieving magnetic glue application.

[0051] In practical use, the heating component can adopt different heating methods, such as electromagnetic heating and infrared heating; the shape of the glue storage box 41 can be optimized according to actual needs. The design of the glue application roller 42 allows the glue to be evenly applied to the magnet surface without dripping due to excessive adhesion, enhancing the bonding effect between the magnet and the cardboard box, and improving product quality and reliability.

[0052] Specifically, the second feeding device 3 includes a receiving member 31 for accommodating magnets, an ejector 32 that reciprocates relative to the receiving member 31, a magnet feeding member 33 that cooperates with the receiving member 31, and a fourth driving member 34 that connects to the magnet feeding member 33 and drives it to reciprocate. The magnet feeding member 33 and the ejector 32 move in opposite directions, and the ejector 32 transfers the magnets in the receiving member 31 to the magnet feeding member 33.

[0053] Please see the appendix Figure 6 As shown, attached Figure 6 The receiving space of the receiving member 31 is designed to be cylindrical, i.e., to accommodate cylindrical magnets. In actual use, a rectangular hole can be provided through the middle of the receiving member 31 to accommodate square magnets. Similarly, the gripper 552 of the magnet picking member 55 can be designed with a curved surface or a flat surface to accommodate round or square magnets. The surface of the gripper 552 is covered with a removable silicone anti-slip part to enhance friction and ensure the gripping stability of square or round magnets.

[0054] In this embodiment, the second feeding device 3 is connected to the output end of the first lead screw module 91 via the third linkage 90 and works in conjunction with the positioning device 9. Both the second feeding device 3 and the positioning device 9 are provided in two sets. Similarly, the magnet picking component 55 at the end of the mounting robot is also provided in two sets. This dual-station setup further improves the magnet mounting efficiency.

[0055] In this embodiment, the ejector 32 is driven by a linear motor 320. The receiving member 31 is formed by splicing two plates with grooves to form a receiving space 311 for accommodating magnets. In actual use, multiple bar magnets can be placed in the receiving space 311 first, and the ejector 32 is driven by the linear motor 320 to eject the magnets out of the receiving space 311 one by one. The magnet feeder 33 is a non-magnetic block with a receiving groove 331 for accommodating magnets in the middle. In the non-working state, the magnet feeder 33 is located below the receiving member 31, and the receiving groove 331 corresponds to the receiving space 311.

[0056] In specific operation, the linear motor 320 drives the ejector 32 to eject the magnet in the accommodating space 311 into the accommodating groove 331 of the magnet feeder 33. The fourth drive 34 (in this embodiment, a cylinder) pushes the magnet feeder 33 to reciprocate to cooperate with the picking and feeding action. The magnet feeder 33 is also provided with two grooves that communicate with the accommodating groove 331 to facilitate the picking action of the magnet picker 55.

[0057] This design ensures a stable and accurate supply of magnets, guaranteeing that the placement robot 5 can acquire magnets in a timely manner and maintain the continuity of the placement process.

[0058] Specifically, the material-applying robot 5 consists of a third support member 51, a first lateral movement mechanism 52 and a first lifting mechanism 53 disposed on the third support member 51, a first linkage member 54 connecting the two, and a magnet pickup member 55 disposed at the output end of the first lifting mechanism 53. The first lateral movement mechanism 52 and the first lifting mechanism 53 move in opposite directions.

[0059] The first lateral movement mechanism 52 includes a fifth driving member 521, a synchronous belt pulley assembly 522 connected to the fifth driving member 521, and a first guide rail slider assembly 523 connected to the synchronous belt pulley assembly 522. A first linkage member 54 is connected between the toothed belt of the synchronous belt pulley assembly 522 and the slider of the first guide rail slider assembly 523. The first lifting mechanism 53 includes a second lead screw module 531 disposed on the first linkage member 54 and a sixth driving member 532 connected to the input end of the second lead screw module 531. A magnetic pickup member 55 is connected to the output end of the second lead screw module 531. The output end of the first lifting mechanism 53 is provided with a second linkage member 533. Multiple sets of magnetic pickup members 55 are slidably disposed on the second linkage member 533. The output end of the second lead screw module 531 is provided with a proximity switch 534. The mounting equipment of this utility model has a control system that is electrically coordinated with each device. The proximity switch 534 is electrically coordinated with the fifth driving member 521 through the control system to prevent the magnet from being completely immersed in the glue storage box 41.

[0060] Specifically, the magnet pickup component 55 can use a parallel opening and closing cylinder 551 to drive two grippers 552 to pick up magnets. In actual use, the magnet pickup component 55 can use a vacuum suction cup assembly to drive the suction cup to pick up the magnet, or use an electromagnet assembly to energize and attract the magnet. Multiple pickup methods can also be combined and automatically switched according to the different characteristics of the magnet and production needs. The grippers 552, suction cup, and other components are optimized to improve pickup stability. This utility model provides multiple magnet pickup methods to meet the pickup needs of different types of magnets, improving the applicability and flexibility of the equipment.

[0061] This utility model features a material-attaching robot 5 composed of a third support member 51, a first lateral movement mechanism 52, a first lifting mechanism 53, a first linkage member 54, and a magnet-picking member 55. This robot performs cross-movements in the lateral and lifting directions, enabling flexible and precise magnet picking and attaching operations. The synchronous pulley assembly 522, in conjunction with the guide rail slider assembly, achieves smooth and rapid lateral movement. The second lead screw module 531, in conjunction with the sixth drive member 532, performs lifting actions, ensuring the accuracy of the picking and attaching positions.

[0062] Multiple sets of magnet pickup components 55 are slidably mounted on the second linkage component 533, which can simultaneously pick up or attach multiple magnets, improving work efficiency. The proximity switch 534 can detect the position of the output end of the second lead screw module 531 in real time, and through the control system and electrical cooperation with the fifth drive component 521, it effectively prevents the magnet driven by the magnet pickup component 55 from being completely immersed in the glue storage box 41, avoiding excessive glue on the magnet and affecting the mounting quality, thereby greatly improving the operational stability and product yield of the equipment, and enhancing the overall automation level and reliability of use.

[0063] Specifically, this invention adds a discharge device 7 and a discharge robot 8 to the automatic magnet attaching equipment. The structure of the discharge device 7 is the same as that of the first feeding device 2, receiving cartons by longitudinal conveying. The discharge robot 8 is mounted on the frame 1, and its movement direction intersects with the conveying direction of the discharge device 7. It drives the second guide rail slider assembly 82 to achieve linear reciprocating motion through the seventh drive component 81 (servo motor). The transfer component 83 connected to the slider assembly moves in a direction perpendicular to the first conveyor belt 22, accurately transferring the cartons with magnets attached on the attaching worktable 6 from the worktable to the discharge device 7, facilitating subsequent packaging or circulation. The entire discharge process is automated, the movement is smooth, and the cartons are accurately positioned and reliably transferred.

[0064] This solution, by setting up a discharging robot 8 in conjunction with a discharging device 7, not only achieves automatic transfer of cardboard boxes, reducing manual intervention and improving the overall production cycle, but also, because the moving direction of the discharging component 83 is perpendicular to the direction of the conveyor belt, and the moving direction of the discharging device 7 intersects with the moving direction of the robot, the overall layout of the equipment is compact and reasonable, occupying little space and effectively improving the utilization rate of the production line. At the same time, the cooperation between the second guide rail slider assembly 82 and the seventh drive component 81 ensures high precision and high stability of the transfer action, avoiding product scratches or drops caused by poor transfer, thereby further improving the yield of magnet-mounted finished products and the reliability of equipment operation.

[0065] The following summarizes the workflow of the automatic magnet mounting equipment of this utility model, based on the specific embodiments described above:

[0066] The automatic magnet attaching equipment for cardboard boxes provided by this utility model uses a frame 1 as the basic platform, on which a first feeding device 2, a second feeding device 3, an adhesive feeding device 4, a attaching robot 5, an attaching worktable 6, an output device 7, and a matching output robot 8 are installed in sequence. The layout of each part is compact and reasonable, and the functions are clear. The overall workflow is as follows: The first feeding device 2 delivers the outer cardboard boxes to the pasting worktable 6 in an orderly manner via the first conveyor belt 22. The positioning device 9, driven by the first lead screw module 91, precisely positions the cardboard boxes using the first positioning component 92 and the second positioning component 93. Simultaneously, the second feeding device 3 supplies magnets to the magnet feeding component 33 in an orderly manner. The magnet picking component 55 then picks up the magnets using the cross-cooperation of the traversing and lifting mechanisms of the pasting robot 5. After being coated with glue by the glue storage box 41 and the glue application roller 42 of the glue supply device 4, the magnets are precisely pasted onto the designated positions on the cardboard boxes. After pasting, the cardboard boxes are transferred from the pasting worktable 6 to the unloading device 7 by the unloading robot 8 via the cooperation of the second guide rail slider assembly 82 and the removal component 83. From there, the unloading device 7 transfers the boxes to subsequent processes or performs centralized processing. The entire process is fully automated from cardboard box supply and magnet pasting to finished product transfer through the control system coordinating various driving components, sensors, and detection devices, significantly improving production cycle time and operational continuity.
