Based on the transfer device status information, transfer device location information, transfer device attribute information, blank storage location information, and blank attribute information, determine a target material transfer device that meets the material transportation conditions from among the material transfer devices.

[0077] For an embodiment of the present invention, after determining the transfer device status information, transfer device position information, transfer device attribute information, and the blank storage location information and blank attribute information of each material transfer device, it is necessary to select a target material transfer device that meets the material conveying conditions based on the above information. Based on this, step 203 specifically includes: based on the transfer device status information, determining an idle material transfer device in an idle state in each of the material transfer devices; based on the transfer device attribute information and the blank attribute information, determining a material accommodating transfer device that can accommodate the NdFeB blank at one time in the idle material transfer device; based on the transfer device position information and the blank storage location information, calculating the material fetching distance between the material accommodating transfer device and the NdFeB blank storage location; based on the material fetching distance, determining a target material transfer device that meets the material conveying conditions in the material accommodating transfer device.

[0078] Specifically, there are multiple material transfer devices in the production site of NdFeB magnets. Each material transfer device may include a material transfer device that is in operation and a material transfer device that is in an idle state, as well as whether there are residues from the previous conveying process in the idle material transfer device. Based on this, it is necessary to select an idle material transfer device that is in an idle state and has no residues from each material transfer device according to the status information of each material transfer device, so as to avoid arbitrarily selecting a material transfer device. If a material transfer device in a working state is selected, it is necessary to reselect, which wastes time. If a material transfer device with residues is selected, the sintering quality of NdFeB magnets is affected. Therefore, the embodiment of the present invention can improve the production efficiency and production accuracy of NdFeB magnets. Furthermore, after determining the idle material transfer device, since the volumes of the various material transfer devices are different, in order to avoid multiple transportations, it is necessary to select a material transfer device that can accommodate NdFeB blanks at one time from among the idle material transfer devices, thereby avoiding the time wasted by using one transfer device for multiple material transfers, or avoiding the resources wasted by using multiple transfer devices for material transfers. Thus, the embodiment of the present invention can improve the material transfer efficiency, thereby improving the production efficiency of NdFeB magnets, and saving material transportation resources. Furthermore, after determining the material transfer device that can accommodate NdFeB blanks at one time, in order to save material retrieval time, it is necessary to select a material transfer device that is closest to the storage location of the NdFeB blanks from among the various material transfer devices, and determine the material transfer device as the target material transfer device that meets the material transportation conditions. By selecting the material transfer device that is closest to the NdFeB blanks to transport the NdFeB blanks, the production efficiency of NdFeB magnets can be further improved.

[0079] Furthermore, after selecting the target material transfer device for conveying the NdFeB blanks, in order to prevent other material transfer processes from occupying the material transfer device, that is, to avoid conflicts caused by two or more material transfer processes selecting the same transfer device, the method further includes: controlling a display device on the target material transfer device to highlight the display in a first preset color. For example, the display device can be a display light on the target material transfer device. If the target material transfer device is occupied, the display light can be set to yellow. When other material transfer processes find that the display light of the target material transfer device is yellow, they will be prohibited from selecting and scheduling the target material transfer device, thereby avoiding confusion in material transfer and ensuring the orderly progress of each material transfer process.

[0080] 204. Based on the sintering device status information, determine an idle sintering device in an idle state among the sintering devices.

[0081] Specifically, there are multiple sintering devices in the production site of NdFeB magnets. Each sintering device may include a sintering device that is in operation and a sintering device that is in an idle state, and whether there are residues from the previous sintering process left in the idle sintering device. Based on this, it is necessary to select a sintering device that is in an idle state and has no residues from each sintering device according to the status information of each sintering device, so as to avoid arbitrarily selecting a sintering device. If a sintering device in a working state is selected, it is necessary to reselect, which wastes time. If a sintering device with residues is selected, the sintering quality of NdFeB magnets is affected. Therefore, the embodiment of the present invention can improve the production efficiency and production accuracy of NdFeB magnets.

[0082] 205. Based on the sintering device attribute information, determine a desired sintering device that meets preset conditions of the sintering process from among the idle sintering devices.

[0083] The sintering device attribute information includes: current temperature information, current pressure information, current vacuum information, current sealing information, and current humidity information of each sintering device.

[0084] For the embodiment of the present invention, in order to improve the manufacturing accuracy of NdFeB magnets, after selecting an idle sintering device in an idle state, it is also necessary to select a desired sintering device that meets the preset conditions of the sintering process from each idle sintering device. Based on this, step 205 includes: based on the current temperature information, determining a temperature-compliant sintering device whose current temperature is within the preset temperature range in the idle sintering device; based on the current pressure information, determining a pressure-compliant sintering device whose current pressure is within the preset pressure range in the idle sintering device; based on the current vacuum degree information, determining a current vacuum-compliant sintering device whose current pressure is within the preset pressure range in the idle sintering device. A vacuum-compliant sintering device with a degree within a preset vacuum range is determined; based on the current sealing information, a sealing-compliant sintering device with a current sealing greater than a preset sealing threshold is determined in the idle sintering device; based on the current humidity information, a humidity-compliant sintering device with a current humidity less than a preset humidity threshold is determined in the idle sintering device; an overlapping sintering device is determined in each of the temperature-compliant sintering device, the pressure-compliant sintering device, the vacuum-compliant sintering device, the sealing-compliant sintering device, and the humidity-compliant sintering device, and the overlapping sintering device is determined as the desired sintering device that meets the preset conditions of the sintering process.

[0085] Among them, the preset temperature range, preset pressure range, preset vacuum range, preset sealing threshold, and preset humidity threshold are set according to actual needs. Since the temperature of the sintering device before sintering is too high or too low, the pressure is too high or too low, the vacuum is too high or too low, the sealing is too low, and the humidity is too low, it will affect the sintering quality, and then affect the production quality of NdFeB magnets. Based on this, in order to improve the sintering quality of NdFeB magnets, it is necessary to select the desired sintering device from each idle sintering device whose current temperature, current pressure, current vacuum, current sealing, and current humidity all meet the actual requirements, so as to improve the sintering quality and then improve the production quality of NdFeB magnets.

[0086] 206. Calculate a transfer distance between the desired sintering device and the NdFeB blank storage location based on the sintering device location information and the blank storage location information of the desired sintering device.

[0087] 207. Based on the transfer distance, determine a target sintering device that meets the sintering requirements among the desired sintering devices.

[0088] Specifically, after determining the desired sintering device, since the volumes of the various sintering devices are different, in order to avoid multiple sintering, it is necessary to select a sintering device that can sinter the NdFeB blanks at one time from among the desired sintering devices, thereby avoiding the time wasted by using one sintering device for multiple sintering, or avoiding the resources wasted by using multiple sintering devices for sintering. Thus, the embodiment of the present invention can improve the sintering efficiency, thereby improving the production efficiency of NdFeB magnets, and saving sintering resources. Furthermore, after determining the sintering device that can sinter the NdFeB blanks at one time, in order to save the material transfer time, it is necessary to select a sintering device that is closest to the storage location of the NdFeB blanks from among the various sintering devices, and determine the sintering device as the target sintering device that meets the sintering requirements. By selecting the sintering device closest to the NdFeB blanks to perform the sintering process of the NdFeB blanks, the production efficiency of NdFeB magnets can be further improved.

[0089] Furthermore, after selecting a target sintering device for sintering the NdFeB blank, in order to prevent other sintering processes from occupying the sintering device, that is, to avoid conflicts caused by two or more sintering processes selecting the same sintering device, the method further includes: controlling a display device on the target sintering device to highlight the display in a second preset color. For example, the display device can be a display light on the target sintering device. If the target sintering device is occupied, the display light can be set to green. When other sintering processes detect that the display light of the target sintering device is green, they will prohibit the selection and scheduling of the target sintering device, thereby avoiding sintering confusion and ensuring the orderly progress of each sintering process.

[0090] 208. Schedule the target material transfer device to transfer the NdFeB blank from the blank storage location to the target sintering device, and based on the sintering process parameter information, control the target sintering device to perform sintering heat treatment on the NdFeB blank, and manufacture NdFeB magnets based on the NdFeB blank after sintering heat treatment.

[0091] According to the embodiment of the present invention, after selecting a target material transfer device that meets the material conveying conditions and a target sintering device that meets the sintering requirements, the target material transfer device is scheduled to transfer the NdFeB blank from the blank storage position to the target sintering device, and the target sintering device is controlled to perform sintering heat treatment on the NdFeB blank according to the sintering process parameter information, thereby obtaining a sintered material. In order to produce NdFeB magnets based on the sintered material, the method further includes: obtaining the current transfer device status information, the current transfer device position information, the current transfer device status information of each current material transfer device in the current production scene corresponding to the NdFeB magnet, The method comprises the following steps: determining the target current material transfer device that meets the material taking conditions based on the current transfer device status information, the current transfer device position information, the current transfer device attribute information, the blank attribute information, and the sintering device position information of the target sintering device, and scheduling the target current material transfer device to take out the NdFeB blank after sintering heat treatment from the target sintering device; scheduling the target current material transfer device to transfer the taken out NdFeB blank after sintering heat treatment to the next manufacturing device for manufacturing NdFeB magnets.

[0092] Among them, the current material transfer device refers to a device such as a mobile box that can obtain and transport materials after sintering treatment in the target sintering device; the current transfer device status information refers to the working status information of each current material transfer device and whether there is residual material inside, etc., and the current working status information refers to whether each current material transfer device is in a working state or an idle state; the current transfer device position information refers to the current position coordinates of each current material transfer device, etc.; the current transfer device attribute information refers to the volume information of the material holding part of each current material transfer device, that is, the capacity, etc.; the blank attribute information of the NdFeB blank after sintering heat treatment refers to the volume information of the material after sintering treatment, etc.

[0093] Specifically, after the target sintering device performs sintering heat treatment on the NdFeB blank, in order to proceed to the next process, it is necessary to obtain the current transfer device status information, current transfer device position information, current transfer device attribute information of each current material transfer device in the current production scene corresponding to the NdFeB magnet, as well as the blank attribute information of the NdFeB blank after sintering heat treatment. Then, based on the above information, select the target current material transfer device that is in an idle state, can accommodate the sintered material at one time, and is closest to the target sintering device. Then, schedule the target current material transfer device to obtain the sintered material from the target sintering device, and transport the sintered material to the next production device for the production of NdFeB magnets. For example, the next production device can be a magnetization device, which magnetizes the sintered material and then performs trimming, testing and other steps on it to complete the production of NdFeB magnets. Therefore, the embodiment of the present invention specifies appropriate sintering process parameters, selects a material transfer device that meets the conveying requirements to convey the materials required for the production of NdFeB magnets, and selects a sintering device that meets the sintering requirements to sinter the NdFeB blanks. This can make the entire NdFeB magnet production process more orderly and accurate, thereby improving the production efficiency and production accuracy of NdFeB magnets, so that the produced NdFeB magnets can meet the needs of users.

[0094] According to another method for manufacturing NdFeB magnets provided by the present invention, compared with the current method of realizing each manufacturing process of NdFeB magnets by manual control, the present invention constructs a preset digital twin model based on the actual manufacturing scene data corresponding to the NdFeB magnets; and in response to the manufacturing signal of the NdFeB magnets, based on the preset digital twin model, obtains the transfer device status information, transfer device position information, transfer device attribute information of each material transfer device in the actual manufacturing scene corresponding to the NdFeB magnets, the sintering device status information, sintering device attribute information, sintering device position information of each sintering device, the blank storage location information and blank attribute information of the NdFeB blanks required for manufacturing NdFeB magnets, and obtains the sintering process parameters corresponding to the NdFeB magnets information; at the same time, based on the transfer device status information, the transfer device position information, the transfer device attribute information, the blank storage position information, and the blank attribute information, a target material transfer device that meets the material transportation conditions is determined in each of the material transfer devices; then, based on the sintering device status information, the sintering device attribute information, the sintering device position information, and the blank storage position information, a target sintering device that meets the sintering requirements is determined in each of the sintering devices; finally, the target material transfer device is scheduled to transfer the NdFeB blank from the blank storage position to the target sintering device, and based on the sintering process parameter information, the target sintering device is controlled to perform sintering heat treatment on the NdFeB blank, and the NdFeB magnet is manufactured based on the NdFeB blank after sintering heat treatment.Therefore, by constructing a preset digital twin model and analyzing the status information, position information, and attribute information of each material transfer device, the status information, position information, and attribute information of each sintering device, and the location information and attribute information of the NdFeB blank through the preset digital twin model, the target material transfer device that meets the material transportation conditions and the target sintering device that meets the sintering requirements are selected, and finally the target material transfer device and the target sintering device are scheduled to sinter the NdFeB blank according to the sintering process parameter information to realize the production process of NdFeB magnets. Therefore, by digitally reconstructing the actual production scene corresponding to the NdFeB magnets, a prototype mirror image of the digital NdFeB magnet production process is built, that is, the preset digital twin model. The preset digital twin model can automatically and accurately The target material transfer device and the target sintering device are determined, and the target material transfer device and the target sintering device are precisely controlled to realize the production process of NdFeB magnets, thereby improving the production efficiency and production accuracy of NdFeB magnets.
