Description
Technical Field
[0001] This application relates to the field of material storage and transportation equipment technology, and in particular to a stacking box with good storage effect for magnet production. Background Technology
[0002] During the production of neodymium iron boron magnets, the raw materials need to be made into compacts first, and then transferred to subsequent work stations for sintering processes to form a dense microstructure with high magnetic properties, while maintaining the degree of orientation obtained during the magnetic field orientation process.
[0003] In the production process of neodymium iron boron magnets, the prepared blanks are typically placed into a stacking box for storage and transfer. During the transfer of the blanks using the stacking box, the inside of the box becomes connected to the outside during the loading and unloading process, allowing air to enter the box. This causes the blanks inside the box to be oxidized by oxygen in the air, thus affecting the performance of the neodymium iron boron magnets produced in the subsequent sintering process. Utility Model Content
[0004] To prevent the pressed blanks from being oxidized during storage and transportation, this application provides a material stacking box with good storage effect for magnet production.
[0005] This application provides a storage bin for magnet production with good storage performance, which adopts the following technical solution: A storage bin for magnet production with good storage effect includes a bin body, partitions, a robotic arm, a fixing component, an adjusting component, and an exhaust component. The bin body has an inlet and an outlet connected to both ends. Both the inlet and outlet are equipped with doors, which are slidably connected to the bin body. Two partitions are provided, both fixedly installed inside the bin body, dividing the interior of the bin body into a first cavity, a second cavity, and a third cavity. A connecting groove is provided on the partition, allowing the first, second, and third cavities to communicate. The robotic arm is fixedly installed in the second cavity and is used for transporting and placing materials; two sets of fixing components are provided on the box body and correspond one-to-one with the box door, and the fixing components are used to fix the box door to the box body; two sets of adjusting components are provided on the box body and correspond one-to-one with the partition, and the adjusting components are used to adjust the communication state of the connecting groove; two sets of exhaust components are provided on the box body and correspond to the first cavity and the third cavity respectively, and the exhaust components are used to exhaust the air in the box body.
[0006] By adopting the above technical solution, when the pressed billet is placed into the box, the operator uses the adjusting component to isolate the connecting groove near the feed inlet, thereby isolating the first cavity and the second cavity. Then, the operator slides open the box door at the feed inlet, places the pressed billet into the first cavity, and then slides to close the box door at the feed inlet. The air in the first cavity is then vented using the exhaust component, and the connecting groove near the feed inlet is connected using the adjusting component, thereby connecting the first cavity and the second cavity. At this time, the robot arm is activated to clamp the pressed billet in the first cavity into the second cavity. After clamping, the connecting groove near the feed inlet is isolated again using the adjusting component, thereby isolating the first cavity and the second cavity again, completing the placement of the pressed billet.
[0007] When the blank is placed in, the adjustment component is used to isolate the first chamber and the second chamber to prevent outside air from entering the second chamber. After the blank is placed in the first chamber, the air in the first chamber is first discharged using the exhaust component, and then the adjustment component is used to connect the first chamber and the second chamber, so that the second chamber is always isolated from the outside air to prevent the blank in the second chamber from being oxidized by oxygen in the outside air.
[0008] When removing the compact from the box, the operator first activates the robotic arm to clamp the compact from the second chamber into the third chamber. After clamping, the operator uses the adjusting component to isolate the connecting groove near the discharge port, thus isolating the second and third chambers. Then, the operator slides open the box door at the discharge port to remove the compact from the third chamber, and then slides the box door at the discharge port to close it. Finally, the operator uses the exhaust component to expel the air from the third chamber, completing the removal of the compact.
[0009] When removing the compact, the manipulator first places the compact into the third cavity. Then, the adjustment component is used to isolate the second cavity from the first cavity. The door is then opened to remove the compact from the third cavity. During the removal process, the second cavity is kept isolated from the outside air to prevent the compact from being oxidized by oxygen in the outside air.
[0010] Optionally, the fixing component includes a first magnetic strip and a second magnetic strip; the first magnetic strip is fixedly disposed on the housing, and the second magnetic strip is fixedly disposed on the door, and there is a mutual attraction between the first magnetic strip and the second magnetic strip.
[0011] By adopting the above technical solution, the first and second magnetic strips are used to fix the two boxes at the openings of the feed inlet and discharge outlet respectively, preventing the boxes from sliding during the transfer process, thus opening the feed inlet and discharge outlet, allowing outside air to enter the box, and further preventing the pressed billet from being oxidized by oxygen in the outside air.
[0012] Optionally, the adjustment assembly includes an adjustment plate and an electric push rod; the adjustment plate is slidably connected to the partition plate, and when the adjustment plate slides to the opening of the connecting groove, the two sides of the connecting groove are isolated; the fixed end of the electric push rod is fixedly connected to the housing, and the electric push rod is used to drive the adjustment plate to slide.
[0013] By adopting the above technical solution, the adjustment plate is slidable by using an electric push rod, thereby realizing the adjustment of the connection state of the connecting groove.
[0014] Optionally, the exhaust assembly includes an exhaust pipe and a first valve; both exhaust pipes pass through the housing and are respectively connected to the first cavity and the third cavity, and an air pump is installed on the exhaust pipe; the first valve is installed on the exhaust pipe.
[0015] By adopting the above technical solution and using an air pump, the air in the first and third chambers can be discharged through the exhaust pipe.
[0016] Optionally, the housing is provided with an inflation assembly, which includes a nitrogen storage tank, a first inflation pipe, and a second inflation pipe. The nitrogen storage tank is fixedly mounted on the housing and contains pre-filled nitrogen. The first inflation pipe is connected at both ends to the nitrogen storage tank and the first cavity, respectively, and a second valve is installed on the first inflation pipe. The second inflation pipe is connected at both ends to the nitrogen storage tank and the third cavity, respectively, and a third valve is installed on the second inflation pipe. An air pump is installed on both the first inflation pipe and the second inflation pipe.
[0017] By adopting the above technical solution, the nitrogen in the nitrogen storage tank is delivered to the first cavity and the third cavity through the first inflation pipe and the second inflation pipe, respectively, by an air pump. This avoids damage to the tank due to negative pressure caused by the air being expelled from the tank. Furthermore, the tank is filled with inactive nitrogen to prevent it from reacting with the pressed blank.
[0018] Optionally, the housing is provided with a detection component, which includes a first oxygen detector and a controller. Two first oxygen detectors are provided and are fixedly installed in the first cavity and the third cavity, respectively. The first oxygen detector is used to detect the oxygen content information in the first cavity and the third cavity and convert it into an oxygen content signal, which is then input to the controller. The controller is fixedly installed on the housing and is electrically connected to the first oxygen detector. The controller is used to receive the oxygen content signal transmitted by the first oxygen detector and display it.
[0019] By adopting the above technical solution, when air is discharged from the first and third chambers, the first oxygen detector detects the oxygen content information in the first and third chambers and displays it on the controller. The operator observes the oxygen content in the first and third chambers through the controller. When the oxygen content in the first and third chambers drops to a preset value, the air in the first and third chambers is completely discharged, and the operator can proceed with subsequent steps to ensure that the air in the first and third chambers is completely discharged, thereby preventing the compact from being oxidized by oxygen in the outside air.
[0020] Optionally, a monitoring component is provided on the housing, the monitoring component including a second oxygen detector and a buzzer. The second oxygen detector is fixedly installed in the second cavity and electrically connected to the controller. The second oxygen detector is used to detect the oxygen content information in the second cavity and convert it into an oxygen content signal, which is then input to the controller. The buzzer is fixedly installed on the housing and electrically connected to the controller. The controller is also used to receive the oxygen content signal transmitted by the second oxygen detector and control the working state of the buzzer.
[0021] By adopting the above technical solution, the second oxygen detector is always in working condition during use, detecting the oxygen content in the second chamber. When the oxygen content in the second chamber exceeds the preset value, the buzzer sounds an alarm to prompt the operator to take timely action to purge the air from the chamber and prevent the pressed blank in the second chamber from being oxidized.
[0022] Optionally, the bottom of the housing is fixedly equipped with casters.
[0023] By adopting the above technical solution, casters are installed at the bottom of the container, making it easier for operators to transport the container.
[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. When placing the compact, the first chamber and the second chamber are isolated by the adjustment component to prevent outside air from entering the second chamber. After placing the compact into the first chamber, the air in the first chamber is first discharged by the exhaust component, and then the first chamber and the second chamber are connected by the adjustment component to keep the second chamber isolated from the outside air and prevent the compact in the second chamber from being oxidized by oxygen in the outside air. 2. When removing the compact, first use a robotic arm to place the compact into the third cavity, then use the adjustment component to isolate the second cavity from the first cavity, and then open the door to remove the compact from the third cavity. During the removal process, the second cavity is kept isolated from the outside air to prevent the compact from being oxidized by oxygen in the outside air. Attached Figure Description

[0034] Reference Figure 1 and Figure 2The housing 1 is equipped with two sets of exhaust assemblies 6, corresponding to the first chamber 14 and the third chamber 16 respectively. Each exhaust assembly 6 includes an exhaust pipe 61 and a first valve 62. The exhaust pipe 61 of one set of exhaust assemblies 6 passes through the housing 1, with one end connected to the first chamber 14 and the other end extending outside the housing 1. The exhaust pipe 61 of the other set of exhaust assemblies 6 also passes through the housing 1, with one end connected to the third chamber 16 and the other end extending outside the housing 1.

[0036] A detection assembly 8 is installed on the housing 1, comprising a first oxygen detector 81 and a controller 82. Two first oxygen detectors 81 are provided, located respectively in the first chamber 14 and the third chamber 16. The first oxygen detectors 81 are fixedly connected to the inner wall of the housing 1. The two first oxygen detectors 81 are used to detect the oxygen content information in the first chamber 14 and the third chamber 16, respectively, and convert this information into oxygen content signals which are then input to the controller 82. The controller 82 is fixedly installed on the outer wall of the housing 1 and is electrically connected to both first oxygen detectors 81. The controller 82 receives the oxygen content signals transmitted by the two first oxygen detectors 81 and displays them on its own display screen.
[0037] A monitoring component 9 is installed on the housing 1, comprising a second oxygen detector 91 and a buzzer 92. The second oxygen detector 91 is located inside the second cavity 15 and is fixedly connected to the inner wall of the housing 1. The second oxygen detector 91 is also electrically connected to the controller 82. The second oxygen detector 91 is used to detect the oxygen content information in the second cavity 15 and convert it into an oxygen content signal, which is then input to the controller 82. The buzzer 92 is fixedly installed on the outer wall of the housing 1 and is electrically connected to the controller 82. The controller 82 is also used to receive the oxygen content signal transmitted by the second oxygen detector 91 and control the buzzer 92 to emit an audible alarm.
[0038] The implementation principle of the storage box with good storage effect for magnet production in this application embodiment is as follows: In use, the operator first pulls and closes both the box doors 13 located at the inlet 11 and outlet 12. At this time, the first magnetic strip 41 and the second magnetic strip 42 are positioned opposite each other, attracting each other and fixing the two box doors 13 to the openings of the inlet 11 and outlet 12 respectively. Then, the operator controls the two electric push rods 52 to retract, thereby driving the two adjusting plates 51 to slide upwards, away from the connecting groove 21, so that the first cavity 14, the second cavity 15 and the third cavity 16 are connected. Then, the operator opens the two first valves 62 and starts the air pump on the exhaust pipe 61. Under the action of the air pump, the air in the box 1 is discharged through the exhaust pipe 61. Then the operator closes the two first valves 62 and opens the second valve 721 and the third valve 731. Then the air pump installed on the first inflation pipe 72 and the second inflation pipe 73 is started. Under the action of the air pump, the nitrogen stored in the nitrogen storage tank 71 enters the tank 1 through the first inflation pipe 72 and the second inflation pipe 73, so that the tank 1 is filled with nitrogen. Then the operator closes the second valve 721 and the third valve 731.
[0039] When the compact is placed in, the operator extends the electric push rod 52 near the feed inlet 11, thereby driving the adjusting plate 51 near the feed inlet 11 to slide down to the slot of the connecting groove 21 near the feed inlet 11, thereby isolating the first cavity 14 and the second cavity 15. Then the operator slides open the box door 13 at the feed inlet 11, puts the compact into the first cavity 14, and then slides to close the box door 13 at the feed inlet 11. Since the first cavity 14 is connected to the outside when the box door 13 is open, outside air enters the first cavity 14. The operator opens the first valve 62 on the exhaust pipe 61 corresponding to the first cavity 14 and starts the air pump on the exhaust pipe 61. Under the action of the air pump, the air in the first cavity 14 is discharged. Then the operator closes the air pump on the exhaust pipe 61 and the first valve 62, starts the second valve 721 and starts the air pump installed on the first inflation pipe 72 to deliver nitrogen from the nitrogen storage tank 71 to the first cavity 14. Then the operator controls the electric push rod 52 near the feed port 11 to retract, thereby driving the adjusting plate 51 near the feed port 11 to slide upward, so that the first cavity 14 and the second cavity 15 are connected. Then the robot arm 3 is activated to clamp the pressed blank in the first cavity 14 into the second cavity 15. After clamping, the electric push rod 52 near the feed port 11 extends, thereby driving the adjusting plate 51 near the feed port 11 to slide downward, so that the first cavity 14 and the second cavity 15 are isolated, completing the placement of the pressed blank.
[0040] Then the operator can push the box 1 and use the casters 17 to transfer the box 1 to the designated position.
[0041] When removing the pressed billet, the operator controls the robotic arm 3 to start, clamping the pressed billet from the second chamber 15 into the third chamber 16. After clamping, the electric push rod 52 near the discharge port 12 extends, thereby causing the adjusting plate 51 near the discharge port 12 to slide downward, isolating the second chamber 15 and the third chamber 16. Then, the operator slides open the box door 13 at the discharge port 12, removes the pressed billet, and then slides to close the box door 13 at the discharge port 12. Because the third chamber 16 is connected to the outside when the box door 13 is open, outside air enters the third chamber 16. The operator opens the first valve 62 on the exhaust pipe 61 corresponding to the third chamber 16 and starts the air pump on the exhaust pipe 61. Under the action of the air pump, the air in the third chamber 16 is discharged. Then the operator closes the air pump and the first valve 62 on the exhaust pipe 61, starts the third valve 731 and starts the air pump installed on the second inflation pipe 73 to deliver nitrogen in the nitrogen storage tank 71 into the third chamber 16, completing the removal of the pressed blank.
[0042] When the air in the first chamber 14 and the third chamber 16 is being expelled, the first oxygen detector 81 is in working condition. The first oxygen detector 81 detects the oxygen content information in the first chamber 14 and the third chamber 16. The operator observes the oxygen content in the first chamber 14 and the third chamber 16 through the controller 82. When the oxygen content in the first chamber 14 and the third chamber 16 drops to a preset value, the air in the first chamber 14 and the third chamber 16 is completely expelled, and the operator can proceed with the subsequent steps.
[0043] During use, the second oxygen detector 91 is in working condition, detecting the oxygen content in the second chamber 15. If the oxygen content in the second chamber 15 is greater than the preset value, the buzzer 92 is controlled by the controller 82 to sound an alarm, prompting the operator to check and promptly vent the air in the chamber 1 to prevent the pressed blank in the second chamber 15 from being oxidized.
[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
