Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, and in particular to a storage and handling device for neodymium iron boron green blanks. Background Technology

[0002] After NdFeB (neodymium iron boron) is pressed into green blanks, its high reactivity means it will spontaneously combust upon exposure to air. Current standard procedures involve first evacuating the NdFeB green blanks in a nitrogen chamber, then removing them and sealing them in an oil drum before manually transferring them to the sintering process. In the sintering process, the vacuum packaging is removed in a nitrogen chamber environment, and the blanks are unsealed before sintering. This process requires three people to work together for vacuuming, oil sealing, transfer, and unsealing, resulting in low production efficiency from pressing to sintering. Furthermore, the vacuum packaging may still be exposed to air during the oil sealing process, posing a risk of spontaneous combustion and compromising production safety. Utility Model Content

Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis.

[0023] like Figures 1 to 5 As shown, a storage and handling device for neodymium iron boron blanks includes a first box 1 and a feeding and discharging mechanism 2, a moving conveying mechanism 3 and a stacking storage mechanism 4 disposed in the first box 1. The first box 1 is sealed, and an air vent valve 11 is provided on the top wall of the first box 1 and a nitrogen inlet valve 12 is provided on the bottom side wall of the first box 1. The feeding and discharging mechanism 2 is disposed on the outer side wall of the first box 1. The feeding and discharging mechanism 2 includes a second box 21 and a feeding and discharging roller assembly 22 and a door opening and closing assembly 23 disposed inside the second box 21. The second box 21 has a first feeding and discharging port 211 on the side wall away from the first box 1. The second box 21 is open on the side closer to the first box 1. The first box 1 has a second feeding and discharging port 13 on the side wall closer to the second box 21 along its own length direction. The second feeding and discharging port 13 is disposed corresponding to the open side wall of the second box 21. The door opening and closing assembly 23 is used to close and open the second feeding and discharging port 13. The mobile conveying mechanism 3 includes a mobile drive component 31 and a first conveyor belt 32. The stacked storage mechanism 4 includes multiple second conveyor belts 41 arranged at intervals along the vertical direction. The first conveyor belt 32 and the second conveyor belts 41 are both disposed inside the first housing 1. The first conveyor belt 32 and the second conveyor belts 41 are both arranged along the length direction of the first housing 1. The first conveyor belt 32 is disposed between the second conveyor belts 41 and the infeed / outfeed roller assembly 22. The mobile drive component 31 is used to drive the first conveyor belt 32 to move along the vertical direction. The feed roller assembly 22, the first conveyor belt 32 and the second conveyor belt 41 are respectively used to convey the graphite box 101 containing the neodymium iron boron blank 100.

[0024] The working principle of the storage and handling equipment for NdFeB green blanks 100 is as follows: The door assembly 23 is normally closed, meaning it only opens to transfer the graphite box 101 when the storage and handling equipment is connected to the forming press or the sintering furnace. This ensures the entire process of transferring the NdFeB green billet 100 is conducted in a nitrogen-protected environment. Since the door assembly 23 is normally closed, the second inlet / outlet 13 is also normally closed. When the second inlet / outlet 13 is closed, the first housing 1 is sealed. At this time, the air outlet valve 11 and the nitrogen inlet valve 12 are opened, and nitrogen is introduced from the bottom of the first housing 1. Simultaneously, air is discharged from the top of the first housing 1. When the oxygen content inside the first housing 1 reaches below 0.02%, meaning air is completely isolated, the air outlet valve 11 and the nitrogen inlet valve 12 are closed. The method of first introducing nitrogen ensures complete air isolation inside the first housing 1.

[0025] After nitrogen is filled into the first housing 1, the storage and handling equipment is sealed and connected to the molding press. Specifically, the first inlet / outlet 211 is the interface for connecting with the molding press of the previous process and the sintering furnace of the subsequent process. The first inlet / outlet 211 is connected to the interface of the molding press. The interface of the molding press is provided with soft rubber. When the first inlet / outlet 211 is connected to the interface of the molding press, it can be sealed by the soft rubber.

[0026] After docking with the forming press, the opening and closing door assembly 23 opens the second inlet / outlet 13. The moving drive assembly 31 drives the first conveyor belt 32 to move up and down until its surface is on the same horizontal plane as the surface of the inlet / outlet roller assembly 22. The pressed NdFeB green blank 100 is loaded into the graphite box 101 in the forming press without vacuum packaging. Then, the graphite box 101 enters the inlet / outlet roller assembly 22 in the second housing 21 through the first inlet / outlet 211. Under the conveying of the inlet / outlet roller assembly 22, the graphite box 101 passes through the second inlet / outlet 13 and is conveyed to the first conveyor belt 32. The moving drive assembly 31 drives the first conveyor belt 32 to move up and down until its surface is on the same horizontal plane as the surface of one of the second conveyor belts 41. Then, the first conveyor belt 32 transports the graphite box 101 to the second conveyor belt 41. After the first conveyor belt 32 transports the graphite box 101 to one of the second conveyor belts 41, the moving drive assembly 31 drives the first conveyor belt 32 to move up and down until its surface is on the same horizontal plane as the surface of the feed roller assembly 22. The first conveyor belt 32 repeats the process of receiving the graphite box 101 from the feed roller assembly 22 and transferring the graphite box 101 to the stacked second conveyor belts 41 for stacking until all the second conveyor belts 41 have stacked the graphite box 101. Then, the opening and closing door assembly 23 closes the second feed port 13, and the storage and handling equipment disconnects from the interface of the forming press, transferring the neodymium iron boron green billet 100 to the next process.

[0027] Similar to the docking principle with the forming press, the first inlet / outlet 211 is docked with the docking interface of the sintering furnace. The docking interface of the sintering furnace is provided with soft rubber. When the first inlet / outlet 211 is docked with the docking interface of the sintering furnace, it can be sealed by the soft rubber.

[0028] After docking with the sintering furnace, the transfer begins. The door opening assembly 23 opens the second inlet / outlet 13. The moving drive assembly 31 drives the first conveyor belt 32 to move up and down until its surface is on the same horizontal plane as the surface of one of the second conveyor belts 41. The second conveyor belt 41 transports the graphite box 101 onto the first conveyor belt 32. The moving drive assembly 31 then drives the first conveyor belt 32 to move up and down until its surface is on the same horizontal plane as the inlet / outlet roller assembly 22. The first conveyor belt 32 transports the graphite box 101 onto the inlet / outlet roller assembly 22. Under the transport of the first conveyor belt 32, the graphite box 101 passes through the second inlet / outlet 13. The graphite box 101 enters the sintering furnace through the first inlet / outlet 211. After being transported to the sintering furnace, the moving drive assembly 31 drives the first conveyor belt 32 to move up and down until its surface is on the same horizontal plane as the surface of any of the second conveyor belts 41 that have not unloaded the graphite box 101. The first conveyor belt 32 repeats the process of receiving the graphite box 101 from the second conveyor belts 41 and transporting the graphite box 101 to the sintering furnace for unloading until all the graphite boxes 101 on the second conveyor belts 41 have been unloaded. Then, the door opening and closing assembly 23 closes the second inlet / outlet 13, and the storage and handling equipment disconnects from the interface with the sintering furnace, thus completing the transfer process. Specifically, the graphite box 101 not only serves as a transfer tool but will also be sintered together with the NdFeB green billet 100 in the sintering furnace.

[0029] The aforementioned storage and handling equipment for NdFeB green blanks 100 enables the transfer and sealed storage of NdFeB green blanks 100 from pressing to sintering. During transfer, the NdFeB green blanks 100 are sealed within the first housing 1. The first housing 1 provides a nitrogen-protected environment throughout the transfer process, eliminating the need for vacuuming, oil sealing, and unsealing, significantly improving production efficiency. Simultaneously, it effectively enhances the production safety of the NdFeB green blanks 100 transfer process, solving the technical problems of low production efficiency and poor transfer safety caused by low transfer efficiency of existing NdFeB blanks. Furthermore, by setting the moving conveyor mechanism 3 and the stacked storage mechanism 4, multi-layer stacked storage of graphite boxes 101 containing NdFeB green blanks 100 can be achieved, effectively increasing the number of NdFeB green blanks 100 transferred in the same transfer process, further improving production efficiency.

[0030] To further explain, the door opening and closing assembly 23 includes a first drive device 231, a lifting seat 232, a connecting arm 233, and a door panel 234. The first drive device 231 is fixedly installed in the second housing 21. The lifting seat 232, the connecting arm 233, and the door panel 234 are all installed inside the second housing 21. The door panel 234 is installed corresponding to the second inlet / outlet 13 and is used to close and open the second inlet / outlet 13. The output end of the first driving device 231 is fixedly connected to the lifting seat 232, the lifting seat 232 is fixedly connected to one end of the connecting arm 233, and the other end of the connecting arm 233 is fixedly connected to the door panel 234; the first driving device 231 drives the lifting seat 232 to move up and down, thereby driving the door panel 234 to move up and down to close and open the second inlet / outlet port 13.

[0031] By setting the first driving device 231, the first driving device 231 drives the lifting seat 232 to move up and down, and the lifting seat 232 drives the door panel 234 to move up and down through the connecting arm 233, so as to realize the closing and opening of the second inlet and outlet port 13 by the switch assembly.

[0032] Specifically, the first driving device 231 is a cylinder, which has high driving efficiency. The base of the first driving device 231 is fixedly installed on the outer wall of the top of the second housing 21. The piston rod of the first driving device 231 passes through the top surface of the second housing 21 and enters the interior of the second housing 21. The first driving device 231 is located at the center of the second housing 21, and the output end of the first driving device 231 is fixedly connected to the center of the lifting seat 232 to ensure the stability of the lifting seat 232 driven by the first driving device 231. Since the door panel 234 is correspondingly arranged with the second inlet / outlet 13, the door panel 234 is located on one side of the support base. The door panel 234 is connected to the lifting seat 232 through the connecting arm 233, which enables the lifting seat 232 to drive the door panel 234 to move up and down.

[0033] Preferably, the door opening and closing assembly 23 further includes a first guide rail 235 and a first slider 236. The first guide rail 235 is fixedly disposed inside the second housing 21 in the vertical direction, and the first guide rail 235 is disposed on both sides of the lifting seat 232 in the length direction. The lifting seat 232 is fixedly connected to the first slider 236 at both ends in the length direction of itself, and the first slider 236 is slidably disposed on the corresponding first guide rail 235.

[0034] By setting the first guide rail 235 and the first slider 236, when the first driving device 231 drives the lifting seat 232 to move up and down, the lifting seat 232 slides along the first guide rail 235 via the first slider 236. Since the first guide rail 235 is set in the up and down direction, the first guide rail 235 can guide the movement direction of the lifting seat 232, so that the door opening and closing assembly 23 can smoothly close and open the second inlet and outlet port 13.

[0035] To further explain, the feed roller assembly 22 includes a roller bracket 221 and at least two rollers 222. The roller bracket 221 is fixedly disposed inside the second housing 21, and the rollers 222 are rotatably disposed on the roller bracket 221. The rolling direction of the rollers 222 is the same as the conveying direction of the first conveyor belt 32. The horizontal plane where the upper end face of the rollers 222 is located is higher than the horizontal plane where the bottom end face of the second feed port 13 is located.

[0036] By configuring the roller bracket 221 and the roller 222, the roller 222 can rotate on the roller bracket 221. When the graphite box 101 enters the second housing 21 from the forming press, the graphite box 101 is placed on the roller 222 and enters the first conveyor belt 32 along the rolling direction of the roller 222. Under the conveying action of the first conveyor belt 32, it enters the interior of the first housing 1. The horizontal plane of the upper end face of the roller 222 is higher than the horizontal plane of the bottom end face of the second inlet / outlet 13, so that the graphite box 101 can pass smoothly through the second inlet / outlet 13.

[0037] Preferably, two rollers 222 are provided, and the two rollers 222 are spaced apart along the conveying direction of the first conveyor belt 32. The feed roller assembly 22 further includes guide seats 223 spaced apart along the length direction of the rollers 222. The guide seat 223 includes a fixing plate 2231 and a guide plate 2232. The fixing plate 2231 is vertically fixed to the roller bracket 221 and is disposed between the two rollers 222. The guide plate 2232 is horizontally disposed on the top surface of the fixing plate 2231. The guide plate 2232 is located above the rollers 222, and the extending direction of the guide plate 2232 is the same as the conveying direction of the first conveyor belt 32.

[0038] By setting the guide seat 223, a channel for the graphite box 101 to pass through is formed between two spaced-apart guide seats 223. The guide plate 2232 can play a guiding role. The graphite box 101 passing through the channel is restricted between the two guide plates 2232 and is conveyed along the extension direction of the guide plate 2232 (that is, the conveying direction of the first conveyor belt 32). This can prevent the graphite box 101 from shifting position when conveyed on the inlet and outlet roller assembly 22, so that the graphite box 101 can be neatly arranged on the first conveyor belt 32 and the second conveyor belt 41.

[0039] To further explain, the mobile drive assembly 31 includes a second drive device 311, a drive gear 312, a driven gear 313, a belt 314, a lead screw 315, and a lead screw nut 316. The second drive device 311 is fixedly mounted on the top surface of the first housing 1. The output shaft of the second drive device 311 is fixedly connected to the drive gear 312. The drive gear 312 and the driven gear 313 are fitted with the belt 314 for linkage. The driven gear 313 is fixedly connected to the end of the lead screw 315. The lead screw nut 316 is threadedly connected to the lead screw 315 and fixedly connected to the first conveyor belt 32. The lead screw 315 is arranged in the vertical direction.

[0040] Specifically, the second driving device 311 is a motor. The second driving device 311 drives the drive gear 312 to rotate. The rotation of the drive gear 312 drives the driven gear 313 to rotate. The rotation of the driven gear 313 drives the lead screw 315 to rotate, so that the lead screw nut 316 moves in the up and down direction, thereby driving the first conveyor belt 32 to move up and down, so as to realize that the moving drive assembly 31 drives the first conveyor belt 32 to move up and down.

[0041] Specifically, two driven gears 313, two lead screws 315, and two lead screw nuts 316 are provided, and each of these components is arranged in a one-to-one correspondence. The lead screws 315 are located on both sides of the first conveyor belt 32 along its conveying direction and are rotatably connected to the first housing 1. The lead screw nuts 316 are fixedly connected to the two side walls of the first conveyor belt 32 along its conveying direction, ensuring good stability when the second drive device 311 drives the first conveyor belt 32 to move up and down. Preferably, sliders can also be fixedly installed on the two side walls of the first conveyor belt 32 along its conveying direction, and slide rails can be fixedly installed inside the second housing 21 along its vertical direction. The combination of slide rails and sliders guides the movement of the first conveyor belt 32.

[0042] To further explain, the first housing 1 includes a support frame 14 and an outer shell 15, the outer shell 15 is fixedly disposed on the outer surface of the support frame 14, and the second conveyor belt 41 is fixedly disposed on the support frame 14.

[0043] By setting up the support frame 14 and the outer shell 15, the outer shell 15 can cover the support frame 14 to form a sealed internal space, and the support frame 14 can support the installation of the second conveyor belt 41. Specifically, the second conveyor belt 41 is arranged in two rows along the conveying direction, and the first conveyor belt 32 is also arranged in two rows along the conveying direction, thereby enabling the conveying of two rows of graphite boxes 101 at the same time, improving production efficiency.

[0044] Specifically, both the first conveyor belt 32 and the second conveyor belt 41 are powered roller conveyor belts, the roller 222 of the infeed and discharge roller assembly 22 is a non-powered roller, the length of the graphite box 101 is greater than the width of the second box 21, when the graphite box 101 is conveyed into the storage and handling equipment, one end of it first passes through the roller 222 to reach the first conveyor belt 32, and under the conveying power of the first conveyor belt 32, it moves further on the roller 222 to the first conveyor belt 32.

[0045] Preferably, the support frame 14 is rectangular in shape, specifically composed of horizontally arranged frame strips and vertically arranged frame strips forming the rectangular support frame 14. Figure 3 Only the vertically positioned frame is shown in the image.

[0046] Preferably, the side wall of the outer casing 15 is provided with a plurality of observation plates 151, which are respectively provided for the second conveyor belt 41, the upper part of the mobile conveying mechanism 3 and the lower part of the mobile conveying mechanism 3.

[0047] By setting the observation plate 151, it is convenient to observe the situation inside the first box 1. Specifically, the observation plate 151 can be made of transparent acrylic sheet. By setting multiple observation plates 151, it is possible to observe the situation of the second conveyor belt 41 storing NdFeB green blanks 100, the situation of the first conveyor belt 32 conveying, and the situation of the bottom of the first box 1.

[0048] Preferably, the side wall of the outer casing 15 is provided with a cleaning port 152 and a second inlet / outlet 13, the cleaning port 152 is correspondingly provided with a cleaning door 153, and the cleaning port 152 is located below the second inlet / outlet 13.

[0049] Since the neodymium iron boron blank 100 is made of powder metallurgy, dust may fall on the bottom of the first box 1 during transportation and storage. When the storage and handling equipment has been used for a long time, the dust on the bottom of the first box 1 can be cleaned by opening the cleaning door 153 and cleaning the cleaning port 152.

[0050] It should be noted that the cleaning door 153 is equipped with a door lock. When the storage and handling equipment is in operation, the cleaning door 153 is normally closed to ensure that the interior of the first box 1 is sealed.

[0051] To further explain, the bottom of the outer casing 15 is provided with a foot cup 154 ​​and casters, and the foot cup 154 ​​and the casters are respectively located at the four corners of the outer casing 15.

[0052] By providing the foot cup 154 ​​and the casters at the bottom of the housing 15, when it is necessary to fix the position of the storage and handling equipment for docking with the forming press or sintering furnace, the foot cup 154 ​​is adjusted to contact and press against the ground, and the casters are locked, so that the storage and handling equipment is locked in a fixed position. When it is necessary to move the storage and handling equipment for transfer (such as transferring the storage and handling equipment from the forming press to the sintering furnace), the foot cup 154 ​​and the casters are adjusted so that the foot cup 154 ​​is lifted off the ground and the casters are unlocked, and the storage and handling equipment can be moved to the required position under the action of the casters.

[0053] Preferably, an oxygen content tester is installed on the inner wall of the first housing 1. The oxygen content tester is used to monitor the oxygen content inside the first housing 1. During the receiving (loading), transfer, stacking, storage, and subsequent unloading and removal of the graphite box 101 by the storage and handling equipment, if the oxygen content inside the first housing 1 is below 0.02% and the nitrogen content is above 99.98%, the storage and handling equipment will sound an alarm when the oxygen content tester detects an oxygen content above 0.02% to remind personnel to refill with nitrogen. Specifically, during the transfer of the graphite box 101 by the storage and handling equipment, there will be a fixed nitrogen filling pipeline interface in the workshop. When the oxygen content inside the first housing 1 is too high, nitrogen can be replenished midway.

[0054] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
