Description

Technical Field

[0001] This invention relates to the field of packaging box production equipment technology, specifically to a production line and method for producing magnetic packaging boxes. Background Technology

[0002] Magnetic packaging boxes have become the mainstream choice for high-end packaging in the fields of gifts, electronic products, and cosmetics due to their advantages of convenient opening and closing, excellent sealing, and high-quality feel. The market demand for their production volume and quality continues to increase.

[0003] The production process of traditional magnetic packaging boxes relies heavily on segmented manual operation or single-process equipment, which has obvious drawbacks: poor coordination between processes and difficulty in unifying the production rhythm lead to low overall production efficiency; the subjectivity and uncertainty of manual operation result in poor consistency in product size and assembly accuracy; especially in the precise assembly of magnetic components, manual placement of magnetic components is prone to problems such as misalignment and omission, which not only seriously affects the magnetic opening and closing performance of the magnetic packaging box, but also damages the overall aesthetics of the packaging box due to assembly defects, failing to meet the quality requirements of the high-end packaging market.

[0004] Therefore, existing technologies need to be improved. Summary of the Invention

[0005] The technical problem to be solved by this invention is the low efficiency and low assembly accuracy of magnetic components in the production of traditional magnetic packaging boxes. The purpose is to provide a production line and method for producing magnetic packaging boxes, which adopts corresponding technical means and has the beneficial effects of high production efficiency and high assembly accuracy.

[0006] This invention is achieved through the following technical solution:

[0007] In a first aspect, the present invention provides a production line for manufacturing magnetic packaging boxes, comprising a raw material feeding unit, a feeding and assembly unit, a folding and forming unit, a quality inspection unit, a finished product sorting and unloading unit, and a central control system arranged sequentially.

[0008] The raw material feeding unit includes a raw material rack, a loading and transfer robot, and a feeding conveyor belt. The loading and transfer robot transfers the packaging box substrate to the feeding conveyor belt.

[0009] The loading and assembly unit includes a magnetic component vibratory feeder, a vision positioning module, a multi-axis robotic arm, and a pressing mechanism. The multi-axis robotic arm is equipped with an adsorption clamp at its end. Based on the coordinate information from the vision positioning module, it picks up the magnetic component from the outlet of the vibratory feeder and places it at the mounting position on the packaging box substrate.

[0010] The folding and forming unit includes a folding assembly, which controls the side panels of the packaging box substrate to automatically fold through the central control system.

[0011] Furthermore, in this invention, the side of the aforementioned feeding conveyor belt is provided with a mounting pressing platform and a first pusher plate that pushes toward the mounting pressing platform. The side of the mounting pressing platform is provided with a second pusher plate that pushes toward the feeding conveyor belt. The packaging box substrate is mounted with a magnetic suction component on the mounting pressing platform and pressed by the pressing mechanism.

[0012] Furthermore, in this invention, the aforementioned adsorption clamp includes a housing connected to the multi-axis robotic arm. An adsorption electromagnet and an electric lifting rod are disposed within the housing. The telescopic end of the electric lifting rod is fixedly connected to the adsorption electromagnet. A pressure sensor is disposed at the connection point between the telescopic end of the electric lifting rod and the adsorption electromagnet. An opening for the adsorption electromagnet to extend is provided at the lower end of the housing.

[0013] When the pressure sensor detects that the pressure increases when the adsorption electromagnet is close to the magnetic attractor with the same pole facing upward, the central control system controls the adsorption electromagnet to reverse its magnetic pole.

[0014] Furthermore, in this invention, the opening described above is provided with a horn channel for adjusting the lateral position of the magnetic attractor, the top of the horn channel is connected to an alignment channel, the attracting electromagnet is located at the center of the alignment channel, and the inner diameter of the alignment channel is adapted to the outer diameter of the magnetic attractor.

[0015] Furthermore, in this invention, the adsorption bottom surface of the aforementioned adsorption electromagnet is coated with lubricating oil.

[0016] Furthermore, in this invention, the adsorption bottom surface of the aforementioned adsorption electromagnet is provided with a plurality of ball bearings.

[0017] Furthermore, in this invention, the sidewall of the magnetic suction member is provided with a guide slope that is adapted to the sidewall of the speaker channel, and the guide slope of the magnetic suction member is symmetrical in the upper and lower parts.

[0018] Furthermore, in this invention, the aforementioned quality inspection unit includes a magnetic attraction performance inspection module and an appearance inspection module; the magnetic attraction performance inspection module includes a magnetometer for detecting the magnetic force at the magnetic opening and closing point of the packaging box; the appearance inspection module includes a high-definition industrial camera and an image recognition system for identifying whether scratches or stains exist, and unqualified products are pushed to the waste collection area by a rejection pusher, while qualified products are transported to the finished product sorting and unloading unit.

[0019] Furthermore, in this invention, the finished product sorting and unloading unit described above includes an unloading and transfer robot; the central control system controls the unloading and transfer robot to place the packaging box into the finished product storage box.

[0020] Secondly, the present invention also provides a production method, which includes the aforementioned production line for producing magnetic packaging boxes, and further includes the following steps.

[0021] Step 1: The packaging box substrate is stored in the raw material rack of the raw material feeding unit. The loading and transfer robot grabs the packaging box substrate and transfers it to the feeding conveyor belt. The feeding conveyor belt transports the packaging box substrate to the corresponding workstation of the loading and assembly unit at a uniform speed.

[0022] Step 2: The central control system controls the magnetic component vibratory feeder to transport the magnetic components to the discharge port in an orderly manner. The vision positioning module collects the information of the installation position of the magnetic components on the packaging box substrate and feeds it back to the central control system. The central control system controls the multi-axis robotic arm to move the adsorption clamp to the discharge port of the vibratory feeder. After the adsorption clamp picks up the magnetic component, it moves to the installation position of the packaging box substrate and places it. Then, the pressing mechanism presses and fixes the connection between the magnetic component and the packaging box substrate.

[0023] Step 3: The packaging box substrate with the magnetic attachment assembled is conveyed to the folding and forming unit by the feeding conveyor belt. The central control system controls the folding component to automatically fold the side panels of the packaging box substrate to complete the folding and forming of the packaging box.

[0024] Step 4: The formed packaging box is conveyed to the quality inspection unit. The magnetic performance testing module uses a magnetometer to detect the magnetic force at the magnetic opening and closing of the packaging box. The appearance inspection module uses a high-definition industrial camera to capture images of the packaging box's appearance. The image recognition system identifies whether the packaging box has scratches or stains. The central control system determines whether the product is qualified. Unqualified products are pushed to the waste collection area by the rejection pusher, and qualified products are conveyed to the finished product sorting and unloading unit.

[0025] Step 5: The central control system controls the unloading and transfer robot of the finished product sorting and unloading unit to grab the qualified magnetic packaging boxes and place them in the finished product storage box, thus completing the production of the magnetic packaging boxes.

[0026] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0027] 1. The entire production process of magnetic packaging boxes has been automated, integrating raw material feeding, magnetic component assembly, folding and forming, quality inspection, and finished product sorting into a single production line. Each process is coordinated by a central control system, which solves the problem of poor process connection in traditional production and greatly improves overall production efficiency.

[0028] 2. The magnetic component assembly process employs a combination of visual positioning, a multi-axis robotic arm, and a specialized adsorption clamp. The visual positioning module ensures precise positioning of the installation location, while the adsorption clamp automatically centers the magnetic components through a horn channel, an alignment channel, and a guide slope. Combined with a pressure sensor and magnetic pole reversal control, this effectively avoids issues such as magnetic component misalignment and omissions, improves the assembly accuracy of the magnetic components, and ensures the magnetic performance of the packaging box.

[0029] 3. The quality inspection unit simultaneously detects magnetic performance and appearance quality, automatically rejecting unqualified products, effectively improving product consistency and overall quality, and reducing the defect rate. Attached Figure Description

[0041] Example 1

[0042] This embodiment 1 provides a production line for manufacturing magnetic packaging boxes, such as... Figures 1-7 As shown, the system includes a raw material feeding unit 1, a feeding and assembly unit 2, a folding and forming unit 3, a quality inspection unit, a finished product sorting and unloading unit, and a central control system arranged in sequence. Each unit is electrically connected to the central control system, which coordinates and controls the working rhythm and motion precision.

[0043] Combination Figure 1 As shown, the raw material feeding unit 1 includes a raw material rack 101, a loading and transfer robot 102, and a feeding conveyor belt 103. The raw material rack 101 is used to store the packaging box substrate 6 to be processed in layers. The execution end of the loading and transfer robot 102 is equipped with a vacuum suction cup clamp adapted to the packaging box substrate 6, which can grab the packaging box substrate 6 on the raw material rack 101 and transfer it smoothly to the feeding conveyor belt 103. The feeding conveyor belt 103 is a multi-segment frequency conversion speed regulation conveyor belt, which can adjust the conveying speed according to the production rhythm of subsequent processes to achieve uniform and continuous conveying of the packaging box substrate 6.

[0044] Combination Figure 1 and Figure 3As shown, a mounting and pressing table 8 is provided on the side of the feeding conveyor belt 103, and a first pusher plate 801 is provided on the side of the mounting and pressing table 8. A second pusher plate 802 is provided on the side of the mounting and pressing table 8, which is also provided on the side of the feeding conveyor belt 103. Both the first pusher plate 801 and the second pusher plate 802 are driven by servo motors. The packaging box substrate 6 can be transferred from the feeding conveyor belt 103 to the mounting and pressing table 8 under the push of the first pusher plate 801. After the mounting and pressing table 8 completes the installation and pressing of the magnetic suction component 5, it is pushed back to the feeding conveyor belt 103 by the second pusher plate 802 to enter the next process.

[0045] In this embodiment 1, combined with Figure 2 As shown, the loading and assembly unit 2 includes a magnetic component vibratory feeder 201, a vision positioning module, a multi-axis robotic arm 202, and a pressing mechanism; the magnetic component vibratory feeder 201 is made of non-magnetic materials. The discharge port of the magnetic component vibratory feeder 201 is equipped with a feeding trough, which can use vibration to organize the disordered magnetic components 5 into a uniform arrangement and transport them orderly to the picking position along the feeding trough. The multi-axis robotic arm 202 is a six-axis robotic arm. The vision positioning module includes a high-definition industrial camera and an image positioning algorithm module. The high-definition industrial camera is mounted on the multi-axis robotic arm 202, which can collect information in real time and feed the information back to the central control system. An adsorption gripper 7 is installed at the end of the multi-axis robotic arm 202, which can complete the picking and placing of the magnetic components 5 based on the image information from the vision positioning module.

[0046] It should be noted that the pressing mechanism is a pneumatic pressing machine, and its pressing head is equipped with an elastic buffer pad, which can ensure a firm pressing while avoiding damage to the packaging box substrate 6 and the magnetic suction part 5.

[0047] Furthermore, in combination Figure 2 and Figure 5 As shown, the adsorption clamp 7 includes a housing 701 connected to the multi-axis robotic arm 202. The housing 701 contains an adsorption electromagnet 703, an electric lifting rod 702, and a pressure sensor 4. The fixed end of the electric lifting rod 702 is connected to the top inner wall of the housing 701, and the telescopic end is fixedly connected to the adsorption electromagnet 703. The pressure sensor 4 is located at the connection between the telescopic end of the electric lifting rod 702 and the adsorption electromagnet 703, and can detect the pressure value when the adsorption electromagnet 703 contacts the magnetic suction component 5 in real time.

[0048] Combination Figure 5As shown, the lower end of the housing 701 has an opening for the adsorption electromagnet 703 to extend out. A horn channel 705 and an alignment channel 706 are provided at the opening. The larger diameter end of the horn channel 705 faces outwards from the housing 701, and the smaller diameter end is connected to one end of the alignment channel 706. The inner diameter of the alignment channel 706 is adapted to the outer diameter of the magnetic component 5, and the adsorption electromagnet 703 is located at the center of the alignment channel 706. The horn channel 705 can laterally position the magnetic component 5, ensuring the coaxiality of the magnetic component 5 during adsorption and placement.

[0049] In this embodiment 1, the bottom surface of the electromagnet 703 is coated with a high-temperature resistant, low-friction coefficient lubricating oil, or as shown in the image. Figure 6 As shown, several freely rolling balls 7031 are embedded in the bottom surface of the adsorption. The surface of the balls 7031 protrudes slightly from the bottom surface of the adsorption electromagnet 703, which can reduce the friction between the adsorption electromagnet 703 and the magnetic attractor 5, and facilitate the lateral movement and adjustment of the magnetic attractor 5.

[0050] Combination Figure 5 and Figure 7 As shown, the side wall of the magnetic suction component 5 is provided with a guide slope 501 that is adapted to the side wall of the speaker channel 705, and the guide slope 501 has a symmetrical structure. The magnetic suction component 5 can automatically center itself in the speaker channel 705 by abutting against the side wall of the speaker channel 705 through the guide slope 501, thereby further improving the installation accuracy of the magnetic suction component 5.

[0051] Pressure sensor 4 is electrically connected to the central control system. When pressure sensor 4 detects that the adsorption electromagnet 703 is close to the magnetic suction part 5 with the same pole facing upward, the pressure value will increase due to the magnetic pole repulsion. After receiving the pressure signal, the central control system will immediately control the adsorption electromagnet 703 to reverse the magnetic pole to achieve stable adsorption of the magnetic suction part 5 and avoid failure of the magnetic suction part 5 to grasp due to the reverse magnetic pole.

[0052] In this embodiment, combined with Figure 4 As shown, the folding forming unit 3 includes a folding assembly 301, which consists of a folding cylinder 303, a folding push plate, and a positioning block 302. The folding cylinder 303 is connected to the positioning block 302 to fix the packaging box substrate 6, and then the folding push plates (not shown in the figure) around the perimeter fold the sides of the packaging box substrate 6 in sequence. After folding, the adhesive reserved on the sides of the packaging box substrate 6 is automatically adhered.

[0053] The quality inspection unit includes a magnetic attraction performance inspection module and an appearance inspection module, both electrically connected to the central control system. The magnetic attraction performance inspection module includes a magnetometer and an inspection bracket. The magnetometer is mounted on the inspection bracket and accurately detects the magnetic force of the magnetic component 5 as the packaging box passes by, determining whether the magnetic force meets the preset standard. The appearance inspection module includes several high-definition industrial cameras and an image recognition system. The high-definition industrial cameras are arranged around the inspection station to capture images of the packaging box's appearance from different angles. The image recognition system uses a preset image comparison algorithm to identify defects on the packaging box surface, such as scratches, stains, folded edges, warping, and exposed magnetic components 5.

[0054] The quality inspection unit is also equipped with a rejection pusher and a waste collection area. The rejection pusher is driven by a cylinder. When the central control system determines that the product is unqualified based on the detection results of the magnetic attraction performance detection module and the appearance inspection module, it will control the rejection pusher to push the unqualified product from the conveyor line to the waste collection area.

[0055] The finished product sorting and unloading unit includes an unloading and transfer robot and a finished product storage box. The unloading and transfer robot is a four-axis robotic arm with a vacuum suction cup gripper at its end. Under the control of the central control system, it can accurately grab the magnetically sealed packaging boxes that have passed quality inspection and place them in the finished product storage box in an orderly manner according to the preset placement rules. The placement position of the finished product storage box is equipped with a photoelectric sensor. When the central control system detects that the storage box is full, it will issue an alarm prompt to remind the staff to replace the storage box.

[0056] It should be noted that the central control system is a PLC control system, equipped with a touch screen and a data storage module. The touch screen can set production parameters, display production status in real time, and issue operation commands. The data storage module can record various data in the production process, including production output, pass rate, and working parameters of each process, which facilitates production statistics and process optimization by the staff.

[0057] Example 2

[0058] This embodiment provides a production line for manufacturing magnetic packaging boxes, and also includes a method for manufacturing magnetic packaging boxes. The production line for manufacturing magnetic packaging boxes includes the following steps:

[0059] Step 1: Place the packaging box substrate 6 to be processed in layers on the raw material rack 101 of the raw material feeding unit 1. Set parameters such as the conveying speed of the feeding conveyor belt 103 and the gripping interval of the loading and transfer robot 102 through the central control system. The central control system controls the loading and transfer robot 102 to grab the packaging box substrate 6 from the raw material rack 101 through the vacuum suction cup clamp and smoothly transfer it to the feeding conveyor belt 103. The feeding conveyor belt 103 conveys the packaging box substrate 6 at a uniform speed to the mounting and pressing table 8 corresponding to the loading and assembly unit 2. At this time, the first pusher plate 801 moves to push the packaging box substrate 6 from the feeding conveyor belt 103 to the preset positioning position of the mounting and pressing table 8.

[0060] Step 2: The central control system starts the magnetic component vibratory feeder 201. The vibratory feeder organizes the disordered magnetic components 5 into a uniform arrangement and transports them orderly to the material collection position at the discharge port along the feeding trough. At the same time, the high-definition industrial camera of the vision positioning module collects the installation position coordinate information of the magnetic components 5 on the packaging box substrate 6 on the installation pressing table 8 and feeds the information back to the central control system. According to the coordinate information, the central control system controls the multi-axis robotic arm 202 to move the adsorption clamp 7 to the material collection position at the discharge port of the magnetic component vibratory feeder 201, and controls the electric lifting rod 702 to extend, driving the adsorption electromagnet 703 to approach the magnetic component 5.

[0061] When the pressure sensor 4 detects that the adsorption electromagnet 703 is close to the magnetic chuck 5 and the pressure value increases, it determines that the magnetic chuck 5 is facing upwards with the same pole. The central control system immediately controls the adsorption electromagnet 703 to reverse the magnetic pole. The adsorption electromagnet 703 generates a reverse magnetic force to stably adsorb the magnetic chuck 5. During the adsorption process, the guide slope 501 of the magnetic chuck 5 cooperates with the side wall of the horn channel 705 to achieve automatic centering. Then it enters the alignment channel 706 and fits against the inner wall of the alignment channel 706 to ensure the lateral positioning accuracy of the magnetic chuck 5.

[0062] The multi-axis robotic arm 202 moves the adsorption clamp 7 with the magnetic 5 attached to it to the installation position of the magnetic 5 on the packaging box substrate 6. The central control system controls the electric lifting rod 702 to retract, accurately placing the magnetic 5 in the installation position. Then, the pressing head of the pressing mechanism moves down to press and fix the connection between the magnetic 5 and the packaging box substrate 6. After pressing, the pressing head resets, and the second pusher plate 802 moves to push the packaging box substrate 6 with the magnetic 5 assembled back to the feeding conveyor belt 103.

[0063] Step 3: The packaging box substrate 6, after the magnetic suction component 5 is assembled, is conveyed at a constant speed by the feeding conveyor belt 103 to the processing station of the folding and forming unit 3. The central control system controls the folding cylinders of the folding assembly 301 to extend and retract in a preset sequence and stroke according to the preset size parameters of the packaging box, thereby driving the folding push plate to fold the side plates of the packaging box substrate 6 in a preset direction, thus completing the folding and forming operation of the packaging box. The formed packaging box is then conveyed to the quality inspection unit by the feeding conveyor belt 103.

[0064] Step 4: After the packaging box is formed, it enters the inspection station of the quality inspection unit. The central control system first controls the magnetometer of the magnetic performance detection module to detect the magnetic force of the magnetic component 5 and feeds the detection data back to the central control system. The central control system compares the detection data with the preset magnetic force standard value to determine whether the magnetic performance is qualified.

[0065] Meanwhile, the high-definition industrial camera of the appearance inspection module captures images of the packaging box from different angles. The image recognition system compares the captured images with preset standard appearance images to identify whether there are appearance defects such as scratches, stains, folded edges, warping, or exposed magnetic parts on the surface of the packaging box, and feeds the recognition results back to the central control system.

[0066] If the central control system determines that the product's magnetic attraction performance is unqualified or that it has appearance defects, it controls the rejection pusher to push the unqualified product to the waste collection area; if the product is qualified, it controls the feeding conveyor belt 103 to transport the qualified product to the finished product sorting and unloading unit.

[0067] Step 5: After the qualified magnetic packaging boxes are transported to the unloading station of the finished product sorting and unloading unit, the central control system controls the unloading and transfer robot to accurately grab the packaging boxes with the vacuum suction cup clamps and place them in the finished product storage box in an orderly manner according to the preset placement rules. When the photoelectric sensor of the finished product storage box detects that the storage box is full, the central control system issues an alarm prompt, and the staff replaces the finished product storage box with an empty one. The unloading and transfer robot continues to perform the unloading operation to complete the overall production of the magnetic packaging boxes.

[0068] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

The central control system controls the multi-axis robotic arm (202) to move the adsorption clamp (7) to the discharge port of the vibratory feeder (201). After the adsorption clamp (7) picks up the magnetic suction part (5), it moves to the installation position of the packaging box substrate (6) and places it. Then the pressing mechanism presses and fixes the connection between the magnetic suction part (5) and the packaging box substrate (6). Step 3: The packaging box substrate (6) with the magnetic attachment assembled is conveyed to the folding and forming unit (3) by the feeding conveyor belt (103). The central control system controls the folding component (301) to automatically fold the side plate of the packaging box substrate (6) to complete the folding and forming of the packaging box. Step 4: The formed packaging box is conveyed to the quality inspection unit. The magnetic performance testing module uses a magnetometer to detect the magnetic force at the magnetic opening and closing of the packaging box. The appearance inspection module uses a high-definition industrial camera to capture images of the packaging box's appearance. The image recognition system identifies whether the packaging box has scratches or stains. The central control system determines whether the product is qualified. Unqualified products are pushed to the waste collection area by the rejection pusher, and qualified products are conveyed to the finished product sorting and unloading unit. Step 5: The central control system controls the unloading and transfer robot of the finished product sorting and unloading unit to grab the qualified magnetic packaging boxes and place them in the finished product storage box, thus completing the production of the magnetic packaging boxes.
