Description

Technical Field

[0001] The present invention relates to the technical field of NdFeB magnet assembly, and in particular to a NdFeB magnet production device based on a two-dimensional code and a production process thereof. Background Art

[0002] NdFeB magnets are made of multiple magnets bonded together. This process generally requires multiple steps. Due to the small size of the magnets, they are generally placed on a jig and transferred to each process for processing. A jig generally has multiple groups of magnets placed on it, so that multiple groups of magnets can be processed in each process.

[0003] After each process is completed, the processed magnets need to be tested to confirm whether the process is qualified. For unqualified magnets, traditional magnet processing equipment generally adds an NG channel after each process. After detecting the unqualified magnets, the jig with the unqualified magnets is directly placed in the NG channel and no longer processed. However, since there are multiple groups of magnets on the jig, there are qualified magnets and unqualified magnets after processing. If the jig is directly placed in the NG channel, all the magnets on the jig will be scrapped, resulting in a waste of resources. Another treatment method is to continue to transfer the jig with unqualified magnets to the subsequent processes, so that the unqualified magnets on the jig are processed in the next process like other qualified magnets. This treatment method will also cause a waste of resources, unnecessary processing of unqualified magnets, and it is no longer meaningful to test each process.

[0093] Comparative Example

[0094] Focus on combination Figure 1 and Figure 2 As shown, taking the processing of the second magnet group 140 as an example, the difference between the comparative example and the present embodiment is that an NG material channel 16 is provided in each process. When the process is completed, the detection device 5 detects the workpiece 100. When an unqualified workpiece is detected, the circulation component 2 puts the carrier 18 carrying the unqualified workpiece into the NG material channel 16. Only when all the workpieces 100 carried by the carrier 18 are qualified in the detection, the carrier 18 will continue to be circulated to the next process for processing. The difference between the carrier 18 and the fixture 1 is that the carrier 18 is not provided with a QR code 7, and there is no corresponding code scanning device 4.

[0095] By comparison, it can be seen that in the embodiment, by setting the QR code 7 on the fixture 1, and the QR code 7 on each fixture 1 is different, when the scanning device 4 scans the QR code 7, the controller 6 can retrieve the workpiece quality information on the fixture 1, so as to control the processing device 3 to only process the workpiece 100 that is qualified after the previous process of the fixture 1. In addition, for the fixture 1 that carries both qualified and unqualified workpieces, the qualified workpieces on the fixture 1 will not be discarded as waste, thus avoiding waste of resources, and there is no need to add the NG material channel 16 after each process, thus streamlining the production line and centrally classifying the unloading. In addition, after the workpiece 100 is inspected by the detection device 5, the controller 6 can update the workpiece quality information corresponding to the QR code 7 in the database, and at the same time facilitate the tracking of other production indicators, such as the circulation time and processing time of the workpiece 100.

[0096] The above description is only a preferred embodiment of the present invention and is not a limitation on the design of this case. Any equivalent changes made based on the design key of this case shall fall within the protection scope of this case.
